Description

Mask with disinfection function

Technical Field

The invention belongs to the technical field of medical care, and particularly relates to a mask with a disinfection function.

Background

Infectious diseases are a group of diseases caused by various pathogens that can be transmitted from person to person, animal to animal or human to animal. Typically, the disease is transmitted by direct contact with infected individuals, infected individuals' body fluids and excretions, contaminated objects from infected individuals, and the transmission channels include airborne transmission, water source transmission, food transmission, contact transmission, soil transmission, vertical transmission, and the like. Therefore, according to the intensity of the infectious disease and the transmission path thereof, corresponding isolation measures are adopted, and the method is an effective method for blocking the transmission of pathogens. But many group activities, such as meetings, shopping, etc., are inevitable due to the needs of work and life. However, many infectious diseases, such as new coronavirus pneumonia, have a latency as long as fourteen days, so experts recommend that people keep more than one meter of distance between people in crowded places by paying attention to wearing a mask, washing hands frequently, opening windows and ventilating. In fact, among the three previous actions, wearing a mask is the most effective way to block the virus transmission path. However, the masks on the market are all of a filtering type, the protection principle is to block viruses outside the masks, and because the viruses stuck outside the masks are not killed, the infections can still be caused by the contact of fingers of a wearer, so that the masks are generally disposable, and great waste is caused. Therefore, the mask with the disinfection function can kill viruses and can be used permanently, and has very important significance for preventing the spread and the spread of infectious diseases.

Disclosure of Invention

The invention aims to provide a mask with a disinfection function, which consists of an airtight mask body, an air outlet valve, an inner air inlet pipe, a disinfection liquid tank, an outer air inlet pipe and an air inlet valve. The air-tight mask is made of air-tight materials according to human engineering so as to ensure the tightness of the edge after wearing. One side of the non-breathable mask is provided with an air outlet valve, and the left and right symmetrical lines are provided with an inner air inlet pipe; the air outlet valve and the inner air inlet pipe are hermetically bonded with the cover body. The lower end of the inner air inlet pipe is inserted into the spherical disinfectant tank, the port is positioned at the center of the sphere, and the disinfectant tank is hermetically connected with the inner air inlet pipe. The outer air inlet pipe is a U-shaped pipe, one end of the outer air inlet pipe is hermetically connected with the disinfectant tank, the other end of the outer air inlet pipe is provided with an air inlet valve, and the air inlet valve is fixed on the cover body. The disinfectant is injected into the disinfectant tank.

When the device is worn, the U-shaped pipe of the outer air inlet pipe is opened upwards. When a wearer inhales air, the air outlet valve is closed, the air inlet valve is opened, air enters from the air inlet valve, viruses are adsorbed and killed by disinfectant when passing through the disinfectant in the disinfectant tank, and the disinfected air enters a human body through the inner air inlet pipe; when the wearer exhales, the inlet valve closes, the outlet valve opens, and the exhaled air is exhausted from the outlet valve.

The invention has the beneficial effects that:

1. has the function of disinfection;

2. the disinfectant can be replaced or added;

3. because the liquid level of the disinfectant is lower than the center of the spherical disinfectant tank, no matter how the position of the mask with the disinfection function changes, the liquid in the disinfectant tank cannot flow out of the inner air inlet pipe and the outer air inlet pipe.

4. Because the outer air inlet pipe 5 is a hose, the lower end of the outer air inlet pipe can be ensured not to be exposed out of the liquid level when the head of a wearer inclines.

Detailed Description

As shown in fig. 1, the mask with the disinfection function is composed of a mask body 1, an air outlet valve 2, an inner air inlet pipe 3, a disinfection liquid tank 4, an outer air inlet pipe 5 and an air inlet valve 6. The cover body 1 is made of air-proof material according to human engineering to ensure the tightness of the edge after wearing. One side of the cover body 1 is provided with an air outlet valve 2, and an inner air inlet pipe 3 is arranged on the left-right symmetrical line; the air outlet valve 2 and the inner air inlet pipe 3 are hermetically bonded with the cover body 1. The lower end of the inner air inlet pipe 3 is inserted into the spherical disinfectant tank 4, the port is positioned at the center of the sphere, and the disinfectant tank 4 is hermetically connected with the inner air inlet pipe 3. The outer air inlet pipe 5 is a U-shaped hose, one end of the outer air inlet pipe is hermetically connected with the disinfectant tank 4, the other end of the outer air inlet pipe is provided with an air inlet valve 6, and the air inlet valve 6 is fixed on the cover body 1.

The disinfection solution is injected into the disinfection solution tank 4, the liquid level of the disinfection solution is lower than the center of the spherical disinfection solution tank 4, so that no matter how the position of the mask with the disinfection function changes, the liquid in the disinfection solution tank 4 can not flow out from the inner air inlet pipe 3 and the outer air inlet pipe 5.

The U-shaped tube of the outer air inlet tube 5 opens upward when worn. When a wearer inhales air, the air outlet valve 2 is closed, the air inlet valve 6 is opened, air enters from the air inlet valve 6, viruses are adsorbed and killed by disinfectant when passing through the disinfectant in the disinfectant tank 4, and the disinfected air enters a human body through the inner air inlet pipe 3; when the wearer exhales, the inlet valve 6 closes, the outlet valve 2 opens, and the exhaled air is exhausted from the outlet valve 2.
