Description

  The present invention relates to a vacuum cleaner that significantly reduces odor contained in exhaust gas, and more particularly to a vacuum cleaner using a dust bag.

  In recent years, as the demand for comfort in living environments is increasing, the need for improving the clean function is increasing year by year in vacuum cleaners. In particular, the user is particularly interested in reducing and removing bad odors derived from dust contained in the exhaust. Dust, food residue, hair, sebum and the like sucked into the dust bag are stored in the dust bag for a long period of time, so that oxidation and rot caused by microorganisms progress, resulting in generation of malodorous substances. For this reason, when the vacuum cleaner is operated, a bad odor is contained in the exhaust and released into the room, so that the user feels uncomfortable or receives an unsanitary impression.

As a countermeasure against odors contained in the exhaust of a conventional vacuum cleaner, there has been proposed one in which a deodorizing fragrance is installed in a dust collection indoor space (see, for example, Patent Document 1).
Japanese Patent No. 2810090

  However, in the conventional configuration, a deodorizing fragrance is installed in the dust collection room space where the dust collection bag of the vacuum cleaner is installed, and the deodorizing components are scattered in the dust collection room so that the dust in the dust collection bag Deodorize and relieve exhaust odor during operation, but deodorant fragrance mixes odor with dust odor separately to mitigate exhaust odor, so it does not lead to the removal of the fundamental odor, Furthermore, depending on the type of dust that has been sucked in, there has been a problem that it may be exhausted from the vacuum cleaner as an unpleasant odor.

  Further, in the conventional configuration, in the dust bag vacuum cleaner that can suck a large amount of dust and hold it for a long time, almost all of the suction airflow passes through the dust, so odor is generated as the amount of dust absorption increases. In the state where the amount increases and the dust bag is close to the permissible amount, the generation of odor is greatly increased. Therefore, the deodorizing effect of the deodorant fragrance has a problem that a sufficient effect cannot be obtained.

  The present invention solves the above-mentioned conventional problems, and greatly reduces the odor derived from dust contained in the exhaust when using a vacuum cleaner, and in particular, a dust collection bag type vacuum cleaner that increases the amount of stored dust. Therefore, an object of the present invention is to provide a vacuum cleaner that can obtain a sufficient deodorizing effect regardless of the amount of dust in the dust bag and the storage period, and at the same time, does not generate a strange odor due to the deodorizing action.

  In order to solve the above-described conventional problems, the vacuum cleaner of the present invention includes a deodorizing powder in a dust bag for sucking and storing dust, and an air flow generated in the dust bag when the dust is sucked. As a result, the deodorized powder adheres to the dust.

  As a result, the fine deodorized powder adheres not only to the dust surface but also to the inside of the dust, and prevents the generation of odor from the dust over a long period of time. Moreover, since the deodorized powder can be continuously removed from the odor in the gas phase, no bad odor leaks out of the dust bag.

  The vacuum cleaner of the present invention has a dust collection bag system in which a large amount of dust is stored and a suction airflow passes through the dust. The deodorizing effect can be maintained for a long time until the amount of dust reaches an allowable amount.

  A first aspect of the present invention is a vacuum cleaner that includes a dust collection bag in a dust collection chamber and sucks and stores dust in the dust collection bag by suction air generated by an electric blower. The deodorized powder is attached to the dust in the dust bag by mixing action such as air flow or vibration, thereby removing the odor derived from the dust, thereby continuously storing the dust stored in the dust bag. The deodorizing treatment can be performed and the bad odor contained in the exhaust gas can be greatly reduced.

  In the second invention, in particular, the dust collection bag of the first invention is composed of a plurality of layers of bags, and the deodorized powder is collapsed on the innermost surface side of the plurality of layers of bags through an adhesive means. Because it is fixed in place, part of the deodorized powder collapses and mixes in the dust due to the suction airflow generated by the electric blower and the impact when the sucked dust collides with the dust bag. The deodorized powder diffuses into the dust due to the influence of the airflow, and when the suction airflow passes, it passes through the bag to which the deodorized powder is adhered, so that the odor generation of the dust is suppressed and the generated odor is filtered. Deodorization performance is improved by the removal effect.

  According to a third aspect of the invention, in particular, the dust collection bag of the first aspect of the invention is composed of a plurality of layers of bags, and deodorization is carried out between the outer side of the innermost side bag and the other bags among the plurality of layers of bags. When airflow or vibration is applied to the dust collection bag by enclosing the powder, an appropriate amount of deodorized powder flows out from the innermost bag and adheres to the dust in the dust collection bag, generating odor Can be prevented. At that time, among the multi-layered bags, the inner diameter of the innermost bag is larger than the deodorized powder, and the other bags are smaller in air diameter than the deodorized powder. Even if there is dust absorption by the electric blower, the deodorized powder does not flow out of the dust bag and remains in the dust bag to prevent the generation of odor.

  According to a fourth aspect of the invention, in particular, the dust collection bag of the first invention is provided with a breathable bag in which the deodorized powder is enclosed in the dust collection bag, so that the deodorized powder is contained in the dust collection bag. If the air bag or vibration is applied to the dust bag, an appropriate amount is discharged from the breathable bag and adheres to the dust in the dust bag, preventing the generation of odor. Can do.

  In the fifth invention, in particular, the breathable bag enclosing the deodorized powder of the fourth invention is installed near the top surface or front upper part of the dust bag, and the deodorized powder is removed from the breathable bag. When exhausted partially due to airflow or vibration, it is possible to make the deodorized powder evenly adhere to the dust bag by discharging it from the top or front top of the dust bag. Odor can be efficiently deodorized.

  In the sixth aspect of the invention, in particular, the breathable bag of the fourth aspect or the fifth aspect of the invention has a water-repellent finish, so the humidity of the surrounding atmosphere increases or dust containing moisture is sucked. Even when the inside of the dust bag becomes highly humid, the breathable bag repels moisture by water repellent treatment, so the deodorized powder inside does not absorb moisture and is left indoors for a long time. Even in such a case, the deodorizing performance can always be maintained.

  In the seventh invention, in particular, since the dust collecting bag according to any one of the first to sixth inventions is provided with the vibration applying means for applying vibration, the vibration collecting means applies vibration to the dust collecting bag. Thus, the deodorized powder can be reliably attached to the dust in the dust bag, and the bad odor derived from the dust can be stably removed.

  In the eighth invention, in particular, the vibration means of the seventh invention is operated for a predetermined time after the operation of the electric blower is stopped. Therefore, the deodorized powder is attached to the newly sucked dust in the dust bag. In other words, since the deodorizing process is always performed on the dust at the end of the cleaning operation, no bad odor is generated from the exhaust even when the electric blower is operated at the next cleaning operation.

  In particular, the ninth invention includes a dust detection means and a control means electrically connected to the vibration means in the seventh invention, the dust detection means detects dust being sucked, and the detected signal Based on the above, by operating the vibration means for a predetermined time by the control means, the deodorized powder adheres to the sucked dust unit, and the deodorization performance of malodor against dust can be further enhanced.

  In the tenth invention, the deodorized powder of the first to ninth inventions in particular is a hydrophobic zeolite deodorized powder having a component ratio of 100 parts by weight or more of silica with respect to 1 part by weight of alumina, and has been used for a long time. Even if the deodorized powder is left in the dust bag, the deodorized powder is hydrophobic and difficult to adsorb moisture. It can be demonstrated.

  In the eleventh aspect of the invention, an antibacterial material is blended in the deodorized powder of the first to tenth aspects of the invention. The antibacterial material suppresses the propagation of germs adhering to dust, and moisture is mixed. Occurrence of bad odor due to sudden increase of bacteria in the case can be prevented, and overall deodorization performance against bad odor of dust can be improved.

  In the twelfth aspect of the invention, the blending amount of the antibacterial material with respect to the deodorized powder of the first to eleventh inventions is 1 to 3 parts by weight with respect to 100 parts by weight of the deodorizing powder. By making it appropriate, deodorizing performance and antibacterial performance can be kept in a good balance, which is advantageous in terms of cost.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a schematic cross-sectional view of a dust collection bag used in the electric vacuum cleaner according to the first embodiment of the present invention. FIG. 2 is a schematic cross-sectional view of the electric vacuum cleaner according to the embodiment.

  In FIG. 1, a dust collection bag 1 is composed of an outer bag 2, an inner bag 3 and a wick 4. Usually, a plurality of non-woven fabrics are overlapped and formed into a bag shape. The wick 4 having a circular opening serving as a suction port is bonded and produced.

  Further, deodorized powder 5 is bonded and fixed to the surface of the inner bag 3 through a binder. As a method for bonding and fixing the deodorized powder, a slurry is prepared by dispersing 20 parts by weight of the deodorized powder 5 and 2 parts by weight of a binder in 100 parts by weight of distilled water. As the deodorized powder 5, deodorized powder such as activated carbon, a transition metal catalyst, and zeolite can be used. In the present embodiment, zeolite is used. As the binder, an organic binder or an inorganic binder can be used, but an inorganic binder is preferable from the viewpoint of little influence on thermal stability and performance deterioration of the deodorized powder, and a silica-based inorganic binder was used.

  After immersing the raw material nonwoven fabric of the inner bag 3 in the slurry in which the material is dispersed, drying at 80 ° C. for 8 hours, raising the temperature to 180 ° C., and then holding for 2 hours to complete the adhesive fixing, This nonwoven fabric was used as the inner bag 3 of the dust bag 1.

  In addition, the deodorizing powder 5 can be fixed in a layered manner on the surface of the inner bag 3 nonwoven fabric and the amount of adhesive fixing to the inner bag 3 can be increased by repeating the immersion and drying in the slurry a plurality of times. In the present embodiment, the bonding and fixing operation is performed three times, and the inner bag 3 in which 5 g of deodorized powder 5 is bonded and fixed per dust bag is used.

  Further, the deodorized powder 5 fixed to the nonwoven fabric of the inner bag 3 by the above-described method can be used when a predetermined impact or the like is applied to the deodorized powder 5 from the outside, or when the vacuum cleaner is operated or changed in airflow when stopped. When the dust bag is deformed, or when air pulsation in the dust bag occurs, the binder collapses due to these impacts, and the deodorized powder 5 is easily detached from the inner bag 3, The original powder state can be restored, and the deodorized powder 5 adheres to the dust.

  In the schematic cross-sectional view of the electric vacuum cleaner of FIG. 2, a dust collection chamber 7 and an electric blower 8 are disposed in the electric vacuum cleaner body 6, and a dust collection filter 9 is provided in the ventilation path before and after the electric blower 8. Is arranged. Further, a suction port 10 is opened at the front of the vacuum cleaner main body 6 so as to communicate with the dust collecting chamber 7, and a suction pipe 11 for sucking and introducing dust from the floor surface or the like is connected thereto. .

  Further, an openable / closable lid 12 is incorporated on the upper surface of the vacuum cleaner main body 6 on the dust collection chamber 7 side. The lid 12 is opened, and the dust collection bag 1 with the deodorized powder 5 is attached to the mouthpiece 4. By fitting in a fixed guide (not shown) provided in the dust collection chamber 7, the opening of the wick 4 and the suction port 10 are in communication with each other.

  Further, in the present embodiment, as a means for causing the deodorized powder 5 to collapse and adhere to dust, a vibration means 13 that electrically vibrates the dust bag 1 is incorporated in the dust collection chamber 7. As the vibration means 13, as shown in FIG. 2, a configuration in which a vibration generator 14 such as a solenoid and a vibration transmission plate 15 are combined is preferable in that vibration can be applied over a wide range of the dust collection bag 1. In addition, although the position which applies a vibration is a rear part of the dust bag 1 in FIG. 2, if an appropriate vibration can be applied to the dust bag 1, it will not be limited to this.

  The vibration means 13 is not limited to electrical means, and vibration generated when moving the vacuum cleaner body 6 manually or as long as an amplitude operation can be applied to the dust bag 1. May be used.

  With the above configuration, when the suction fan 11 is generated by the operation of the electric blower 8 and the dust is sucked through the suction pipe 11, the sucked dust is stored in the dust bag 1 and is collected in the dust bag 1. The filtered suction airflow is exhausted to the outside of the electric vacuum cleaner body 6 through the dust collection filter 9. After the cleaning work is finished and the electric blower 8 is stopped, the vibration generator 14 is operated for a predetermined time to apply vibration to the dust bag 1 to collapse a part of the deodorized powder 5 on the inner bag 3. Therefore, the deodorized powder 5 is always adhered to the dust in the dust bag 1.

  The vibration generator 14 may be operated at an arbitrary timing such as before cleaning or during cleaning so that the deodorized powder 5 is attached to the dust, and vibration is generated even when strong odorous dust is sucked. The deodorizing effect can be further enhanced by increasing the number of operations of the generator 14.

  In addition, a series of operations in which the vibrating means 13 is electrically operated at an arbitrary timing to cause the dust bag 1 to vibrate to cause the deodorized powder 5 to collapse and adhere to the dust is performed by a control means (not shown). It is controlled and operated.

  Using the vacuum cleaner of Embodiment 1 configured as described above, the effect of the present invention was verified by experiments.

(Experimental example 1)
Using the above vacuum cleaner, the actual room was cleaned for 15 minutes. After the cleaning was completed, the electric blower 8 was stopped, the vibration means 13 was operated for 5 seconds, and the dust bag 1 was vibrated. As a control experiment, the actual room was cleaned for 15 minutes using an electric vacuum cleaner equipped with an ordinary dust bag without the deodorized powder 5 in the inner bag 3, and this actual room cleaning was continued every day for two months. It was.

  As a result of continuing the cleaning work while sensuously conscious of the exhaust odor, the vacuum cleaner in the control experiment recognized the dusty odor in the exhaust immediately after the start of operation about 3 days after the start of the experiment. First, after that, the intensity of exhaust odor increased over time, and when two months passed, a strong dust odor was always recognized even during operation.

  On the other hand, the vacuum cleaner of this embodiment did not bother the exhaust odor from the start of the experiment to the end of the test, both at the start of operation and during operation.

  The amount of dust collected in this embodiment and the control experiment after two months was almost the same, and about 350 g was sucked.

Next, the vacuum cleaner after two months passed was set in a 1 m ³ sealed chamber and operated for 60 seconds. The air in the chamber was subjected to scent sniffing sensory evaluation by 6 men and women mixed sensory evaluation panelists, and 6-level odor intensity was evaluated from 0 to 5. As a result, the average odor intensity of the present embodiment was 1.2, whereas the average odor intensity of the control experiment was 3.6. Was confirmed to be high.

  Further, as a result of dismantling the dust collection bag 1 of the present embodiment after the experiment was completed, it was observed that almost all of the deodorized powder 5 in the inner bag 3 was detached and adhered to the dust. .

  From the above results, the vacuum cleaner according to the present embodiment reduces the odor generated by the dust even in the case of the dust collection bag system that stores a large amount of dust and holds it for a long period of time. Can be maintained.

  Here, in this embodiment, the extremely high odor reduction effect is obtained for the following reason. That is, the deodorized powder 5 that has fallen from the inner bag 3 becomes an infinite number and adheres around each individual dust, and the contact area with the dust becomes extremely large, so that a high deodorizing performance can be obtained. This is because when viewed as a whole, the deodorized powder 5 is mixed and remains in the dust, and the deodorized powder 5 in the state of being retained continues to deodorize the odor of the dust. In other words, in the present invention, the diameter of the deodorized powder 5 that falls from the inner bag 3 (the diameter of the powder before being hardened with a binder) is the inner bag 3 or the outer bag 2 of the dust bag 1, that is, the entire dust bag 1. Is set in advance so as to be larger than the dust collection bag ventilation diameter, and even if there is dust suction by the electric blower, it remains in the dust collection bag 1 without flowing out of the dust collection bag 1. This is very important. This also applies to each of the embodiments and experimental examples described below.

(Experimental example 2)
As a deodorizing powder according to the present embodiment, a dust collection bag 1 in which a hydrophobic zeolite having a higher silica component ratio than an alumina component ratio in a zeolite is bonded and fixed to the inner bag 3 is used. Went. In this experimental example, the dust bag 1 was stored in a constant temperature and humidity chamber at 35 ° C. and 85% until the next day after the cleaning work was completed, and this was continued until two months after the end of the experiment. As a control experiment, the same experiment was conducted on the dust bag 1 using the normal zeolite of Experimental Example 1.

The vacuum cleaner after 2 months passed was set in a 1 m ³ sealed chamber and operated for 60 seconds, and sensory evaluation was performed in the same manner as in Experimental Example 1. As a result, the specification of the dust collection bag 1 of the hydrophobic zeolite has an average odor intensity of 1.2, whereas the specification of the dust collection bag 1 of the normal zeolite which is a control experiment has an average odor intensity of 1. 1.8.

  From the above results, it was confirmed that by using hydrophobic zeolite as a deodorizing powder, a high deodorizing performance can be realized even in the rainy season or in a high humidity period such as summer.

(Embodiment 2)
FIG. 3 is a schematic cross-sectional view of the dust bag of the electric vacuum cleaner according to the second embodiment of the present invention. FIG. 4 is a schematic structural sectional view of the electric vacuum cleaner according to the embodiment.

  In addition, about the structure same as Embodiment 1, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

  In FIG. 3, reference numeral 16 denotes a breathable bag obtained by processing fibers of a resin material into a bag shape. The deodorized powder 5 is placed in the breathable bag and the open end is sealed. By setting the air gap of the breathable bag within a range of 50 to 100 μm, the deodorized powder hardly comes out of the bag in a static state, and an appropriate amount is discharged when vibration is applied from the outside. be able to. The material of the breathable bag is not limited to the resin material, and may be pulp-based or metal-based.

  The dust bag 1 provided with the deodorized powder 5 can be easily obtained by sticking the breathable bag 16 enclosing the deodorized powder 5 to the inner bag 3 and molding the dust bag 1 when the dust bag 1 is manufactured. . In the present embodiment, 10 g of the deodorized powder 5 is sealed in the breathable bag 16.

  The surface of the resin material of the breathable bag 16 is coated with a silicon polymer so that water repellency against moisture from the outside can be obtained, and the deodorized powder 5 powder in the breathable bag 16 is obtained. Since it becomes possible to maintain a state and deodorizing performance over a long period of time, even if the vacuum cleaner is not used for a long period of time, the deodorizing performance does not deteriorate.

  Moreover, the deodorizing powder 5 can be uniformly attached to the dust in the dust bag 1 by installing the breathable bag 16 in the dust bag 1 on the top surface or the front upper part.

  In FIG. 4, reference numeral 17 denotes dust detection means, which is installed on the upstream side of the intake air flow from the suction port 10. The dust detection means 17 is electrically connected to the vibration generator 14 via the control means 18, and when dust passes through the suction pipe 11, the dust detection means 17 sends a signal to the control means 18. By operating the vibration generator 14 for an arbitrary period of time, vibration is applied to the dust bag 1, and as a result, the deodorized powder 5 is partially discharged from the breathable bag 16, and the dust in the dust bag 1 It will be attached to.

  It should be noted that the operation time of the vibration generator 14 after detecting dust can be adjusted arbitrarily by the user, such as homes where pets are bred, such as homes where pets are strong, etc. Then, the deodorizing effect can be freely set, for example, by increasing the amount of the deodorized powder 5 to be adhered to the dust during one cleaning.

  The effect of the present invention was examined using the electric vacuum cleaner according to Embodiment 2 configured as described above.

(Experimental example 1)
Using the above vacuum cleaner, the actual room was cleaned for 15 minutes. The operation time of the vibration generator 14 at the time of dust detection was 1 second, the deodorized powder 5 was discharged from the breathable bag 16, and the deodorized powder 5 was attached to the sucked dust. As a control experiment, an electric vacuum cleaner equipped with an ordinary dust bag without the deodorized powder 5 was similarly cleaned for 15 minutes. This actual room cleaning was continued every day for two months.

The vacuum cleaner after two months passed was set in a 1 m ³ sealed chamber and operated for 60 seconds to perform sensory evaluation. As a result, the specification of the dust bag 1 of the present embodiment has an average odor intensity of 0.6, while the control experiment has an average odor intensity of 3.6.

  From the above results, this embodiment has been able to deodorize to a level that does not feel the odor derived from dust during the exhaust of the vacuum cleaner, and a higher deodorizing effect is obtained compared to the first embodiment, It was confirmed that a very high deodorizing effect can be realized in the dust bag system that stores a large amount of dust for a long period of time.

(Experimental example 2)
The cleaning work similar to Experimental Example 2 was performed in a pet breeding home. Pets were targeted at homes where dogs were kept indoors. The operating time of the vibration generator 14 when detecting dust according to the present embodiment is set to two levels of 1 second and 3 seconds, and a normal dust collection bag without the deodorized powder 5 is attached as a control experiment. The vacuum cleaner performed the same cleaning work. This actual room cleaning was continued daily for one month each.

  As a result of the sensory evaluation of the vacuum cleaner one month later in the same manner as in Experimental Example 1, the control experiment showed an extremely bad exhaust odor with an average odor intensity of 4.2. When the operating time of the vibration generator 14 was 1 second, the average odor intensity was 1.5, and when the operating time was 3 seconds, the average odor intensity was 0.8.

  From the above results, in the present embodiment, the deodorizing powder 5 can be obtained by increasing the operation time of the vibration generator 14 even in the case of sucking dust with high odor intensity in the dust bag system that increases the amount of stored dust. Therefore, the same high deodorizing effect as in the case of ordinary dust can be obtained.

(Experimental example 3)
In the case of a functional material in the form of powder, it can be easily enclosed in the breathable bag 16 without special processing, and therefore, in addition to the deodorized powder 5, an antibacterial powder is blended. As the antibacterial powder, an inorganic antibacterial material carrying a silver-based oxide is used, and 100 parts by weight of the deodorized powder 5 and 3 parts by weight of the antibacterial powder 19 are mixed with 10 parts by weight. Two types of dust collection bags 1 each having a breathable bag 16 containing a part of the antibacterial powder 19 were prepared.

  As a result of daily cleaning of the actual room for one month with an electric vacuum cleaner incorporating each of the two types of dust collection bags 1, about 150 g of dust was sucked. Using a pipette, a total amount of 15 cc of distilled water was dropped into the dust collection bag in several portions and left in a 35 ° C. incubator for 24 hours. As a control experiment, the same operation was performed with a vacuum cleaner equipped with a normal dust bag without deodorized powder 5 and antibacterial powder.

  After leaving for 24 hours, each dust bag was returned to the electric vacuum cleaner, and sensory evaluation of exhaust odor was performed in the same manner as in Experimental Example 1 and Experimental Example 2. As a result, in the control experiment, the average odor intensity was as high as 4 and a rotten odor such as sulfur-based and amine-based was recognized, whereas this embodiment is independent of the mixing ratio of the antibacterial powder, The average odor intensity was as low as 0.9, and the occurrence of rot odor was suppressed.

  Further, 1 g of dust was collected from each dust bag and the number of bacteria in each dust was measured. As a result, the number of bacteria in the dust of the control experiment was increased 1000 times or more than the initial number of bacteria, whereas the present embodiment has two antibacterial powders with respect to the initial number of bacteria. In both body formulation specifications, the number of bacteria is reduced to 1/10 or less, the proliferation of the number of bacteria in the dust is greatly suppressed, and an antibacterial effect is obtained. It was also confirmed that a sufficient effect was obtained when the mixing ratio with respect to the deodorized powder 5 was 3 parts by weight.

  From the above results, the present embodiment is equipped with a breathable bag in which antibacterial powder is blended with the deodorized powder 5 in the dust bag system that increases the amount of stored dust. In the unlikely event that water is mixed into the dust collection bag 1, it is possible to prevent the growth of bacteria and to prevent the generation of bad odors derived from bacteria from the dust.

  Here, in the present embodiment, the ventilation diameter of the breathable bag 16 is set in advance so as to be larger than the powder diameter of the deodorized powder, and the ventilation diameter of the inner bag 3 is smaller than the powder diameter of the deodorized powder. Even if there is dust absorption by the electric blower, the deodorized powder does not flow out of the dust bag and remains in the dust bag to prevent the generation of odor.

  In the dust bag 1, a mesh bag (not shown) is newly provided inside the inner bag 3, and deodorized powder is sealed between the inner bag 3 and the mesh bag. It is the same as that of the above-mentioned Embodiment 2 by adopting a configuration that is set in advance so as to be larger than the powder diameter of the deodorized powder and the air diameter of the inner bag 3 and the outer bag 2 to be smaller than the powder diameter of the deodorized powder. An effect is obtained.

  As described above, the vacuum cleaner according to the present invention can greatly reduce the odor derived from the dust of the dust bag type vacuum cleaner, and not only a household vacuum cleaner but also a dust bag method. It can be widely applied to mainstream commercial vacuum cleaners and can improve air quality comfort during cleaning work.
