An antibacterial mask capable of long-term continuous charge regeneration

Abstract

The present invention discloses an antibacterial mask capable of long-term continuous charge regeneration, comprising a mask body, ear straps, and a battery. The mask body adopts a multi-layer structure, which is sequentially a barrier layer, a sterilization layer, a filter layer, and a skin-friendly layer. The sterilization layer adopts a nano-silver layer to improve the antibacterial ability of the mask. The filter layer adopts a "semiconductor layer-insulating layer-semiconductor layer" structural design, and the two semiconductor layers are respectively connected to the positive and negative electrodes of an external battery.

The present invention uses a battery to continuously supplement the charge to maintain a stable ability to filter out pathogens. The antibacterial mask capable of charge regeneration of the present invention prevents dust particles, viruses, etc. from invading the human body through two methods: electrostatic capture and physical barrier, so that the mask maintains a high filtering capacity for a long time, saves a large amount of materials and resources, and has the characteristics of green environmental protection.

Description

Technical Field

[0001] The present invention relates to the field of epidemic prevention and protection equipment, and in particular to an antibacterial mask capable of long-term continuous charge regeneration. Background Art

[0002] When a person is infected with a virus, hundreds of millions of new virus particles are constantly produced in the body, especially in the patient's saliva and secretions from the throat and other respiratory tracts. When the patient spreads the virus-containing saliva and droplets into the air through coughing, sneezing, etc., it is very easy to infect the surrounding people who are not properly protected. Therefore, wearing a mask is the most effective way to prevent the virus from invading the human body.

[0003] However, the existing masks circulating on the market have the following defects: 1. Most ordinary masks can only be used for a few hours and have poor filtering effects. In addition, the lost charge cannot be replenished, which will also reduce the filtering efficiency of particles. 2. The mask is tightly sealed, and the breathed air can only be exchanged in the narrow space inside the mask, which can easily cause hypoxia, and the heat is not easy to discharge, which can also cause breathing difficulties for the wearer. 3. The current masks with breathing valves do not have the ability to filter nano-scale particles, so viruses may invade the human body along the valve body. Summary of the invention

[0004] In view of the shortcomings of the prior art, the object of the present invention is to provide an antibacterial mask that can continuously regenerate charge for a long time, has a compact design, is easy to wear and has a good filtering effect.

[0005] An antibacterial mask capable of long-term continuous charge regeneration comprises a mask body, an external battery and ear straps connected to both sides of the mask body. The mask body is provided with a battery slot and a resistor. The mask body is a multi-layer structure, which comprises an isolation layer, a sterilization layer, a filtration layer and a skin-friendly layer from the outside to the inside.

[0006] The present invention provides an antibacterial mask capable of long-term continuous charge regeneration, wherein the battery slots are distributed at the left and right edges of the middle protrusion of the outer mask body, and the two battery slots are connected in parallel and connected in series with a resistor through a wire to prevent breath droplets from connecting two charged layers at the same time, causing a short circuit in the electrical circuit, burning the battery, and thus terminating the function of the mask. The protrusion structure has the function of keeping the mask at an appropriate distance from the face and supporting the structure of the mask body.

[0007] The present invention discloses an antibacterial mask capable of long-term continuous charge regeneration. The isolation layer is made of non-woven fabric, and high-speed hot air is used to draw the polypropylene melt fine stream extruded from the die spinneret hole, thereby forming ultra-fine fibers, which are gathered on a drum and formed into non-woven fabric by self-bonding, thereby preventing droplets, small droplets, etc. from directly entering the mouth and nose, and preventing dust and other large particles from accumulating in the filter layer. The sterilization layer is designed with a double-layer structure of a nano-silver layer and non-woven fabric, thereby improving the sterilization performance of the mask.

[0008] The filter layer adopts a semiconductor layer-insulating layer-semiconductor layer structure, wherein the semiconductor layer is made of molybdenum disulfide material, and the insulating layer is made of non-woven fabric made by polypropylene melt-blown process. One pole of the battery is connected to the semiconductor layer through a wire, and the other pole of the battery is connected to another semiconductor layer.

[0009] The semiconductor layer of molybdenum disulfide is arranged in a sulfur-molybdenum-sulfur structure and has an energy band gap to eliminate the conductive function. Therefore, when connected to a battery, the surface of the semiconductor layer connected to the positive electrode accumulates an appropriate amount of positive charge to form positive static electricity. The surface of the other semiconductor layer connected to the negative electrode accumulates an equal amount of negative charge to form negative static electricity. The two semiconductor layers are separated by an insulating layer.

[0010] The skin-friendly layer is made of high-quality non-woven fabric, which can absorb moisture and also serves as the last barrier to block viruses from entering the respiratory tract.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The invention discloses an antibacterial mask capable of long-term continuous charge regeneration, wherein the mask body is a multi-layer structure, which is composed of a waterproof outer layer, a nanosilver layer, an insulating layer, a negative charge layer, an insulating layer, a positive charge layer, an insulating layer, and a skin-friendly layer from the outside to the inside. Virus particles are prevented from invading the human body by physical isolation and electrostatic capture. The non-woven fabric is skin-friendly, environmentally friendly, and pollution-free, and the non-woven fabric lining has the function of perspiration and moisture absorption, making the wearer feel comfortable.

[0013] The invention discloses an antibacterial mask capable of long-term continuous charge regeneration. The filter layer adopts a "semiconductor layer-insulating layer-semiconductor layer" structural design. The battery replenishes the charge, and an appropriate amount of charge accumulates on the surface of the semiconductor layer to produce an electrostatic adsorption effect. The double electrostatic layer arrangement further enhances the electrostatic capture capability of micro-nano particles such as pathogens.

[0014] The invention discloses an antibacterial mask capable of long-term continuous charge regeneration, wherein a battery is connected to the outer mask body. When the charge is lost during use, the charge can be replenished at any time by the battery, i.e., the charge can be regenerated stably and instantly. The filtering effect of the mask will not be weakened by static electricity loss caused by breathing and contact, so the mask can be reused, which can reduce the waste of materials, has the technical characteristics of green environmental protection, and meets the standards of sustainable development.

[0015] The invention discloses an antibacterial mask capable of long-term continuous charge regeneration, wherein the bactericidal layer contains nano-silver and has a good bactericidal effect.

[0016] The invention discloses an antibacterial mask capable of long-term continuous charge regeneration. The upper edge of the mask body is provided with metal strips to enhance the sealing performance on both sides of the nose wings, so that the mask and the face have a good fit and particles such as viruses are prevented from invading the body through the gaps.

[0017] The antibacterial mask of the present invention can be charged and regenerated for a long time. The battery continuously replenishes the charge, so that the semiconductor layer carries a stable amount of static electricity. The fine particles carrying bacteria and viruses such as droplets and aerosols in the air flow can be electrostatically adsorbed on the filter layer, and the filtration efficiency is not less than 95%. At the same time, the air permeability of the mask is good. Under the condition of an air flow rate of 85L / min during normal breathing of ordinary people, the inhalation resistance is about 80-130Pa, and the exhalation resistance is about 75-125Pa, so that the gas exhaled by the human body can be exchanged with the external gas more smoothly.

[0018] The antibacterial mask capable of long-term continuous charge regeneration adopts a multi-layer non-woven fabric design, which can reduce air flow resistance, reduce heat and moisture accumulation, and improve comfort when worn. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Please refer to the attached Figure 1 , Figure 2 and Figure 3 , Figure 1It is a half structure of a mask, symmetrically arranged on the left and right sides to form a whole. An antibacterial mask capable of long-term continuous charge regeneration in this embodiment comprises a mask body, a battery, and ear straps connected to both sides of the mask body. Two battery slots and a resistor are arranged on the mask body. The battery slots are distributed at the left and right edges of the middle protrusion of the outer mask body, connected in parallel, and connected in series with the resistor through a wire. The mask body of the present invention adopts a multi-layer structure design, which comprises an isolation layer, a sterilization layer, a filtration layer, and a skin-friendly layer from the outside to the inside.

[0025] Two connecting blocks are arranged on both sides of the mask body, and the connecting blocks are respectively connected to the left ear band and the right ear band. A sealing strip is arranged on the upper end of the mask body to prevent airflow from entering from the gaps on both sides of the nose.

[0026] The batteries are connected in parallel and in series with the resistors, such as Figure 3 As shown. In this embodiment, the battery voltage is 10V and the resistance is 1K. If the internal contact is damaged due to long-term use and other reasons to form a loop, the current will not exceed 10mA, ensuring that it is harmless to the human body. The two batteries are arranged in parallel so that when one side of the battery cannot work normally due to insufficient power or poor contact, the other battery can continue to work to ensure continuous electrostatic adsorption capacity. When the power of both batteries is close to exhaustion, the batteries can be easily replaced and continued to be used. When cleaning and disinfecting the mask, the battery must be removed in advance. After cleaning and drying or drying, the battery can be installed and continued to be used.

A large amount of charge accumulates on the surface of the semiconductor layer. When in use, the charge can be continuously replenished on the surface of the semiconductor layer, so that the ability to capture micro-nano particles such as pathogens can be maintained for a long time. The semiconductor layer is molybdenum disulfide, which has an energy band gap and weakens its conductivity; in addition, the molybdenum disulfide semiconductor layer is ultra-thin and soft. The insulating layer is a melt-blown non-woven fabric. In addition to mechanical filtration of particles, the fiber can absorb even smaller particles through molecular attraction.
