Description
Technical Field
The invention relates to the technical field of mask treatment, in particular to a mask treatment device.
Background
A typical protective mask is composed of three layers of material:
1. the surface layer is made of hydrophobically modified PP and PET materials, and has the main function of preventing water drops with large particle size from passing through and attaching the water drops.
2. The inner layer, namely the filter layer, is made of electrostatic electret fiber materials, and an electrostatic electret modified material (mainly PP material) is subjected to melting, hot air auxiliary spraying and high-voltage electrostatic electret to form a filament material with the diameter of 2-5 um, and is piled into a non-woven fabric, and then the filament material is subjected to secondary electrostatic electret to form a filter material with an inter-filament structure and containing an electrostatic field, and when particles pass through, the filter material is adsorbed on the surface under the action of electrostatic force and is further trapped.
3. The attaching layer is made of hydrophilic spun-bonded non-woven fabrics, is soft and non-irritating, and is used for comfortable facial attachment.
The main function of the mask filter efficiency is an inner layer, namely a filter layer.
The factors for reducing the filtering performance of the mask mainly include external factors such as particles, microorganisms and the like which are trapped and attached to reduce the filtering efficiency, internal factors such as vapor contained in exhaled air, droplets generated by coughing and sneezing which are attached to a filtering layer to reduce the electrostatic field intensity, reduce the filtering efficiency and increase the resistance.
When the layers of the mask are enriched with infectious bacterial viruses, particularly, the resistance caused by the increase of the water content of the inner layer increases, the breathing depth increases, and the probability of the filterable infection or the contact infection increases. Therefore, it is suggested that the mask should not be reused many times, which is also a major cause of the shortage of the mask.
The method adopts disinfectant, surface active soaking and washing to remove enriched particulate matters, but simultaneously eliminates the fiber electret charge of the inner layer, loses the filtering effect, and adopts modes of steaming, hot water boiling, oven drying and the like to eliminate the electrostatic electret characteristic and greatly reduce the filtering performance.
If the mask can be rapidly dehydrated, disinfected, deodorized and regenerated in efficiency, the mask efficacy is maintained under the conditions of ensuring the safety and wearing comfort of the mask, so that the mask can be regenerated for use, the shortage situation of the existing mask is greatly slowed down, and the use requirements of the following application scenes are met:
1. Home, wearing for a short time, going out for shopping, entertainment and the like;
2. After meeting, short time contact, periodic regeneration of concentrated office;
3. Service, supermarket cashing, restaurant service, entertainment place service, periodic regeneration;
4. medical treatment, regular regeneration in general occasions;
5. hotels-dining, temporary reception, outgoing, etc.
However, in the prior art, there is still no device capable of rapidly dehydrating, sterilizing, deodorizing and efficiently regenerating the mask, so that it is difficult to safely regenerate the mask.
The ultraviolet rays in the UVC wave band have the capability of killing microorganisms, and the capability and irradiation dose of killing microorganisms such as different viruses and bacteria have been verified by experiments, and the mask is of a multi-layer fiber stacking structure, so that the ultraviolet rays with strong penetrating power are required for rapidly killing deep microorganisms. The pulse xenon lamp which is reasonably designed and provided with a suitable driving circuit can emit strong ultraviolet light with instantaneous power of several kilowatts, has strong penetrability, and is suitable for killing deep microorganisms in a short time.
The infrared absorption peak value of the water and polypropylene material is concentrated at 2-4 um wavelength, an electric heating device which has the wave band emission capability and can be started quickly is adopted, and the water and the PP material can be heated quickly by matching with a heat radiation back reflection and convergence guiding structure, so that moisture contained in the surface is evaporated, and the air and the metal enclosure components in a treatment area are heated less. The quartz halogen heating tube and the carbon fiber heating tube have this characteristic.
Ozone and negative ions have the capability of eliminating odor and killing microorganisms, and fabrics treated by a small amount of ozone have the visual sense of fresh odor.
The electrostatic electret process is a process of ordering dipoles in a high polymer material and is completed with the aid of an external electric field. After the PP fiber material is heated, an external electric field is applied, the electrostatic field lost by the surface of the electret is more easily recovered, and after cooling, the surface electrostatic electret field strength is recovered, so that the trapping capacity of fine particles is recovered.
The exhaust structure formed by the exhaust fan and the filter can form a negative pressure chamber structure of a treatment area, which is similar to a negative pressure isolation cabin of a medical environment, so that water vapor, peculiar smell, trace ozone, fiber falling objects and even microorganisms generated in the treatment process are collected and treated in a concentrated manner, and secondary pollution is avoided.
The components are matched with a proper driving control circuit, a maintenance structure and safety measures, so that the mask in use can be rapidly dehydrated, disinfected, deodorized and efficiently regenerated, and the mask is suitable for effective and comfortable use in non-specific environments. However, there is no such device in the prior art.
