Description

Exhalation device with separation effect

The invention relates to an exhalation device, in particular to an exhalation device with a separation effect.

General cup-shaped masks, if they can be in close contact with the face, and there is a lot of exhaled exhaust gas in the cup, there will be uncomfortable feeling that the hot and humid air in the cup covers the face, and the content of fresh air inhaled will be diluted, resulting in inability to absorb oxygen. Sultry feeling.

Referring to FIG. 1, a surface body 1 with a barrier layer disclosed in the Patent No. M258752 of the Republic of China mainly includes a breathable body 11, and a body 11 disposed on the inner surface of the body 11 and abutting on the face. One partition 12. The partition plate 12 and the main body 11 and the face define a top inner space 121 opposite to the nose and a lower inner space 122 opposite to the mouth. This provides two separate breathing spaces for the nose and mouth. However, although the partition 12 improves the disadvantages of the aforementioned general cup-shaped mask, it still has the following disadvantages:

1. Since the space in the main body 11 is divided into two halves by the partition plate 12, only the breathing area of the nose or mouth will reduce the breathable area by half, which will cause the respiratory resistance to increase and make breathing difficult.

2. In addition, it is important that the partition plate 12 will affect the adhesion effect to the face due to the instability of the combination with the body 11, and the partition plate 12 fixedly connected to the body 11 cannot be used for different face shapes. Users, and affect the effect of close and isolation.

In addition, a one-way valve for improving the sweltering feeling of a mask, such as the filter mask disclosed in Chinese Patent No. CN102695549, which includes a one-way valve, mainly uses a one-way valve to exhaust only one way. Allows air to be expelled quickly and extensively from the inside of the filter mask, reducing exhalation resistance.

However, because the one-way valve only allows gas to flow out and not to flow in, the area occupied by the one-way valve on the filter mask is the ventilation area reduced by the filter mask, so the suction resistance will still increase. Especially when the aforementioned one-way valve is installed in a mask with a partition, no matter where it is installed, the filtering area has been reduced by half, so that the degree of increase in the suction resistance becomes more serious.

Therefore, an object of the present invention is to provide an exhalation device capable of improving space efficiency and the amount of intake air during inhalation, and reducing the respiratory resistance and the feeling of sweltering, and having a separation effect.

Therefore, the exhalation device with the separation effect of the present invention is suitable for being installed in a breathing protector, the breathing protector includes a face, the face having an outer surface and an inner surface opposite to each other, and penetrating the outer surface With a hole in the inner surface, the exhalation device includes: an exhalation valve, and a partition unit.

The exhalation valve is connected to the surface body with respect to the hole of the surface body, and controls the air flow from the inside of the surface body to the outside in one direction, and has an inner plate surface facing the inside of the surface body.

The baffle unit is connected to the inner plate surface of the exhalation valve, and defines an upper air chamber which is separated from the upper body and lower body and is suitable for the nose of the opposite face and the lower air for the mouth of the opposite face. And the control air flow from the lower air chamber to the upper air chamber in one direction.

The effect of the present invention is that the special design of the diaphragm unit combined with the exhalation valve can simplify the assembly elements and the convenience of combining with the surface body, and improve the space efficiency, and the diaphragm unit can make the air flow The function of flowing from the lower air chamber to the upper air chamber, combined with the exhalation valve's function of quickly and massively venting outwards, can also increase the amount of intake air during inhalation, and reduce breathing resistance and sweltering feeling.

And a second positioning portion 43 extending from the top wall relative to the first positioning portion 34. The cavity 40 communicates with the interior of the surface body 21 and the valve port 33 of the valve seat 3. The surrounding wall 41 has a plurality of exhaust ports 411 communicating with the cavity 40 and the outside, facing downward, and two left and right sides. The left and right ends of the second positioning portion 43 and the surrounding wall 41 define two gaps 44.

Referring to FIG. 5 and FIG. 2 and FIG. 7, the first valve flap 5 is an elastic diaphragm, and the arc-shaped recess 352 of the sealing wall 35 covers the sealing wall 35 in an arc, and includes being forced against the sealing wall 35. A fixed portion 51 between the first positioning portion 34 of the valve seat 3 and the second positioning portion 43 of the valve cover 4 and two movable portions 52 and 53 formed at the upper and lower ends. The movable parts 52 and 53 contact the sealing wall 35 and generate a bending moment corresponding to the arc-shaped recessed part 352, and close the upper half 331 and the lower half 332 of the valve port 33, and can be blown by the air flow, and Disengage the sealing wall 35 and open the valve port 33. And in accordance with the maximum length H1 of the upper half 331 of the valve port 33 and the maximum length H2 of the lower half 332 of the valve port 33, the length of the movable portion 52 in the vertical direction is not less than that of the movable portion 53 in the vertical direction. Length while forming a longer arm.

In this embodiment, the partition plate 6 extends in the front-rear direction from a position transversely between the valve ports 33, and is suitable for being disposed on the inner surface 212 of the surface body 21, and defining the upper surface and the surface body 21, An upper air chamber 601 that is separated downward and is suitable for the face of the nose and the upper half 331 of the valve port 33 and a lower air chamber 602 that is suitable for the face of the face and the lower half 332 of the valve port 33, It also includes two abutment edges 60 that abut against the inner surface 212 of the surface body 21, an abutment edge 61 that is connected to one end of the abutment edges 60 and is used for contact with the face, and is connected to the abutment edges The other end of 60 abuts against abutment edge 62 of rail groove 38 of valve seat 3, a contact portion 63 formed on the abutment edge 62, an upper plate surface 64 facing upward, and a downward facing Lower plate surface 65, two air ports 66 penetrating the upper plate surface 64 and the lower plate surface 65 at a distance from the left and right, and a set of fixed portions 67 formed on the upper plate surface 64 and located between the air ports 66 . In this embodiment, the connecting portion 63 is a protruding block, and is detachably engaged with the receiving portion 38 of the valve seat 3.

Referring to FIGS. 8 and 2 and 5, the second valve flap 7 is an elastic diaphragm and covers the upper plate surface 64 of the partition plate 6 relative to the gas ports 66 and has a positioning defining a perforation 70. The portion 71 and two swinging portions 72 extending from the positioning portion 71 to the left and right sides. The perforation 70 is used for the sleeve fixing portion 67 to pass through the sleeve, so that the positioning portion 71 is positioned on the sleeve fixing portion 67. The swinging portions 72 contact the upper plate surface 64 of the partition plate 6 to close the air ports 66, and can be blown by the air flow, and detach from the upper plate surface 64 and open the air ports 66.

Referring to FIG. 7 and FIG. 5, when a person inhales through the mouth or nose, the outside air will pass through the surface body 21 and be separated by the partition plate 6 to form two branches.

One of the shunts enters the lower air chamber 602 from the surface body 21, in addition to providing the person's mouth for inhalation, and with the inhalation action of the nose, or the upper air chamber 602 because of the inhalation The generated negative pressure pushes the two swinging portions 72 of the second valve flap 7 so that the two swinging portions 72 of the second valve flap 7 are away from the upper plate surface 64 of the partition plate 6 and are opposite to the lower air chamber. 602 direction, and the ports 66 should be opened. Thereby, a part of the air flow in the lower air chamber 602 is caused to flow toward the air ports 66 of the partition plate 6, and the gas is allowed to enter the upper air chamber 601 in one direction.

The other shunt is directly entering the upper air chamber 601 from the surface body 21, and is merged with the air flow entering the upper air chamber 601 from the lower air chamber 602 to increase the air intake of the upper air chamber 601. Provides human nasal inhalation. Thereby, for the nasal inhalation action, a sufficient amount of air can still be obtained, and it will not be because the filtering area of the upper air chamber 601 is small, or because the area of the surface body 21 is exhaled by the breath. The valve occupies and an inhalation impedance is created.

It is worth noting that during the process of inhaling by the mouth or nose, the two movable parts 52 and 53 of the first flap 5 of the exhalation valve will be blocked due to the negative pressure generated by the inhalation action. In the case of the sealing wall 35 of the valve seat 5, the upper half 331 and the lower half 332 of the valve wall 33 that are close to the sealing wall 35 and closed, so that external air cannot enter the cover through the exhalation valve. 21 inside.

Referring to FIG. 9 and FIG. 5, when a person exhales exhaust gas through the nose, the exhaled gas will be blocked by the partition plate 6 and the second valve flap 7 so that the airflow cannot flow into the lower air chamber 602 and is limited to the Inside the upper air chamber 601.

At this time, in addition to the air flowing out of the outside through the surface body 21, the upper air chamber 601 also pushes the movable part 52 of the first valve flap 5 due to the positive pressure generated by exhalation, so that the movable part 52 Move in the cavity 40 in a direction opposite to the valve port 33 and open the upper half 331 of the valve port 33. As a result, the exhaust gas in the upper air chamber 601 passes through the upper half 331 of the valve port 33 and enters the cavity 40 in one direction, and then the valve cover 4 faces the exhaust ports on the lower side and the left and right sides. The 411 exhausts the air and reduces the exhaust pressure.

It is worth noting that, because the length of the movable portion 52 of the first valve flap 5 is longer, a longer arm can be formed. Therefore, even if the pressure of the gas exhaled from the nose is small, it can be easily pushed. Active section 52. And when the movable part 52 of the first valve flap 5 opens the upper half of the valve port 33, the airflow entering the cavity 40 from the upper air chamber 601 through the upper half 331 of the valve port 33 will be directed toward the valve The cover 4 flows in the direction, and after being blocked by the top wall 42 of the valve cover 4, the exhaust ports 411 below and on the left and right sides are exhausted to the outside, and the gaps 44 facilitate the airflow downward. flow. Due to the airflow blocked by the top wall 42, compared with the movable portion 53 of the first valve flap 5, it is blocked by the partition ribs 37, and the movable portion 53 is close to the sealing wall 35, mainly Because of the design of the aforementioned arc-shaped recessed portion 352, the gas discharged from the upper air chamber 601 will not lift the movable portion 53 of the first valve flap 5, and will not allow external air to enter the lower air chamber 602 through the movable portion 53. .

When a person exhales exhaust gas through the mouth, the exhaled gas will enter the lower air chamber 602, except that it will be discharged to the outside through the surface body 21, and will be separated by the partition plate 6 to form a two-way shunt.

One of the shunts pushes the two swinging portions 72 of the second valve flap 7 so that the two swinging portions 72 of the second valve flap 7 are away from the upper plate surface 64 of the partition plate 6 and are opposite to the lower air chamber. 602 direction, and the ports 66 should be opened. As a result, part of the airflow in the lower air chamber 602 is caused to flow toward the air ports 66 of the partition plate 6, and the gas is allowed to enter the upper air chamber 601 in one direction, and then discharged to the outside as described in paragraph [0027].

Another shunt in the lower air chamber 602 will directly push the movable part 53 of the first valve flap 5 due to the positive pressure generated when exhaling, so that the movable part 53 faces the valve opening in the opposite direction. The direction of 33 moves in the cavity 40, and the lower half 332 of the valve port 33 is opened. As a result, the exhaust gas in the lower air chamber 602 passes through the lower half 332 of the valve port 33 and enters the cavity 40 in one direction, and the valve cover 4 directly faces the exhaust gas on the lower side and the left and right sides. The port 411 exhausts air to reduce exhaust pressure.

It is worth noting that since most of the exhaust gas exhaled from the mouth can be quickly and in large quantities discharged from the lower air chamber 602 through the lower half 332 of the valve port 33, a small amount of exhaust gas will also pass through the first Two valve flaps 7 are discharged from the upper air chamber 601 through the upper half 331 of the valve port 33. As a result, for the upper air chamber 601, only a small part of the exhaust gas exhaled by the mouth is entered, and it will also be discharged to the outside. Therefore, the aversion component and mouth foam of the exhaust gas entering the upper air chamber 601 can be greatly reduced.

12, FIG. 10, and FIG. 11, a second embodiment of the present invention is substantially the same as the first embodiment, except that:

The valve seat 3 has a first positioning portion 34 'and a receiving portion 38' formed on the outer plate surface 32 and the inner plate surface 31 and below the valve port 33.

The partition plate 6 of the partition unit extends from the position below the valve port 33 in the front-rear direction, and defines an upper and lower separation from the surface body 21, and is suitable for the nose portion facing the face and the upper air of the valve port 33. The chamber 601 and the lower air chamber 602 adapted to the mouth portion facing the face.

The first valve flap 5 extends in the up-down direction, and has a fixing portion 54 formed at one end portion and fixed relative to the first positioning portion 34 ′ of the valve seat 3, and the other end portion is formed and can be pushed and opened by the air flow. A movable portion 55 of the valve port 33.

When a person inhales through the mouth or nose, it is similar to the description in paragraphs [0022] to [0025], and will not be repeated here.

When a person exhales exhaust gas through the nose, in addition to exhaling the gas through the surface body 21, it will also be blocked by the partition plate 6 and the second valve flap 7, so that the airflow cannot flow into the lower air chamber. 602, and is limited to the upper air chamber 601.

At this time, in addition to the exhaust gas in the upper air chamber 601 being discharged to the outside through the surface body 21, the movable part 55 of the first valve flap 5 is pushed due to the positive pressure generated by the exhalation, so that the The movable portion 55 moves in the cavity 40 in a direction opposite to the valve port 33 and opens the valve port 3. Thereby, the exhaust gas in the upper air chamber 601 passes through the valve port 33 and enters the cavity 40 in one direction, and then the valve cover 4 faces the exhaust ports 411 downward and on the left and right sides to exhaust outward. And the gaps 44 facilitate the downward flow of the airflow.

When a person exhales exhaust gas through the mouth, the exhaled gas will enter the lower air chamber 602, in addition to being discharged to the outside through the surface body 21, and will push the two swinging portions 72 of the second valve flap 7, so that The two swinging portions 72 of the second valve flap 7 move away from the upper plate surface 64 of the partition plate 6 in a direction opposite to the lower air chamber 602, and the air ports 66 are opened. As a result, part of the airflow in the lower air chamber 602 flows toward the air ports 66 of the partition plate 6, and the gas is allowed to enter the upper air chamber 601 in one direction, and then is discharged to the outside as described in paragraph [0039], and It can also reduce exhaust pressure.

Referring to FIG. 14 and FIG. 15, a third embodiment of the present invention is substantially the same as the second embodiment, except that:

The valve seat 3 further includes two support portions 30 extending from the left and right sides in accordance with the inner surface 211 of the planar body 21. Each support portion 30 has two clamping walls 302 spaced apart from each other and defining a guide rail 301, and two ribs 303 that abut against the inner surface 211 of the surface body 21 and extend upward and downward from the guide rail 301.

The abutment edge 62 of the partition plate 6 abuts the inner surface 212 of the surface body 21 and the guide rail 301 of the valve seat 3.

Thereby, the support body 30 is used to support the surface body 21 while maintaining the relative position of the partition plate 6 with the surface body 21 and the face. The ribs 303 are further used to improve the isolation effect and avoid the second valve flap. The swinging portion 72 of 7 is interfered by the surface body 21 when swinging, and the wearing comfort is improved. Since those with ordinary knowledge in the art can infer the extended details based on the above description, they will not be described further.

In addition, it should be noted that the above embodiments can also be used in conjunction with the airtight surface body 21. When the noodle body 21 is an airtight noodle body, a filter unit is additionally provided on the noodle body 21, but the same effect can be achieved through the exhalation device of the present invention, which can quickly and massively exhaust outward, and can also improve the inhalation time. The amount of air intake, and reduce breathing resistance and smoldering. In addition, the guide rails of the foregoing embodiments can also be provided on the surface body 21 to further improve the stability of the exhalation valve and the partition unit when combined with the surface body 21.

As shown in FIG. 16, the partition plate 6 further includes an inner extension section 68 and an upper extension section 69. The inwardly extending section 68 extends inward from the abutment edge 62, and then turns upwards to become the upper extending section 69, and then turns inwardly to become a main part of the upper plate surface 64. When the partition plate 6 abuts on the lower lip of the face, in the absence of the upper extension 69, the valve seat 3 will be installed at the upper position of the surface body 2. Therefore, the valve seat 3 can be adjusted to the center position of the surface body 2 only by changing the length of the upper extension 69 in the vertical direction. The inner extension section 68, the upper extension section 69, and the inner plate surface 31 of the valve seat 3 are surrounded to form an open upward space. The aforementioned open space allows the gas of the upper air chamber 601 to flow to the valve hole 33. The upper half portion 331 further solves the problem of blocking the upper half portion 331 of the valve hole 33. Or the angle of the upper plate surface 64 and the lower plate surface 65 relative to the abutment edge 62 can be changed, and the lift angle of the partition plate 6 relative to the valve seat 3 can be changed, thereby adjusting the abutting edge of the partition plate 6 The abutment position of 61 with respect to the face further improves the loading comfort.

Through the above description, the advantages of the foregoing embodiments can be summarized as follows:

1. With the special design of the valve seat 3 of the exhalation valve in combination with the partition plate 6 of the partition unit of the present invention, it is possible to simplify the components when assembled with the surface body 21 and the convenience when combining with the surface body 21 And improve space efficiency.

2. With the design of the partition unit, the present invention can confine the exhaust gas exhaled in the nose to the upper air chamber 601, reduce the area covered by the exhaled exhaust gas body, not only reduce the sweltering feeling, and reduce the amount of exhaled exhaust gas retention, The fresh air content is increased during inhalation, and the exhaust gas can be quickly discharged to the outside through the exhalation valve, reducing the exhalation resistance.

3. Except that the exhaust gas exhaled from the mouth will be discharged to the outside through the surface body 21, in the first embodiment, the upper air chamber 601 and the lower air chamber 602 can be quickly and separately passed through the exhalation valve. A large amount is discharged from the outside. In the second embodiment, the upper air chamber 601 is discharged from the outside through the exhalation valve to reduce the exhalation resistance and increase the willingness to use.

4. As mentioned above, in the first embodiment, most of the exhaust gas exhaled from the port can be discharged quickly and in large quantities from the lower air chamber 602 through the lower half 332 of the valve port 33. For the upper air chamber 601, since only a small part of the exhaust gas exhaled by the mouth is entered, and it will also be discharged to the outside, the aversive components and mouth foam of the exhaust gas entering the upper air chamber 601 can be greatly reduced.

5. With the detachable design of the partition plate 6 and the connection relationship with the valve seat 3, in addition to being applicable to users with different face shapes or face sizes, the support of the third embodiment can also be used. The portion 30 stretches the surface body 21 and maintains the relative positions of the partition plate 6 and the surface body 21 and the face, further improving the isolation effect and the wearing comfort.

6. Compared with the exhaust gas exhaled from the mouth, the pressure of the exhaust gas exhaled from the nose is usually smaller, and the present invention adopts the design that the length of the movable portion 52 of the first valve flap 5 is greater than the length of the movable portion 52, which can be borrowed. By the action of the force arm, the exhaust gas exhaled from the nose can easily push the movable part 52, so that the nose has a lower exhalation resistance.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, any simple equivalent changes and modifications made according to the scope of the patent application and the contents of the patent specification of the present invention are still Within the scope of the invention patent.
