Description

Head-mounted anti-virus respirator

technical field

The utility model relates to a head-mounted anti-virus respirator, which belongs to the field of cleaning appliances.

Background technique

Viruses are only about one-hundredth the size of bacteria and have no cellular structure. Some viruses are about 100 nanometers (0.1 microns) in size, but there are also very small common viruses, such as coronaviruses that are 30 nanometers (0.03 microns), and foot-and-mouth disease viruses that are as small as 7-8 nanometers. General masks have a better filtering effect on larger particles, such as 2.5 micron and 0.3 micron particles, and also have a certain effect on bacteria, but the effect on viruses that can easily pass through the bacterial filter is not ideal.

Ordinary masks use people to actively inhale, which is laborious and stuffy. It is difficult to completely seal the face and the mask, and it is prone to the risk of viruses and other microorganisms entering through the gaps. The gas exhaled by a person goes out from the gap of the mask, which often causes the glasses of the wearer to fog up. Moreover, the gas exhaled by a person will remain in the mask and will be inhaled again when inhaling next time, which is not healthy. Due to being penetrated by a large number of human exhaled high humidity and gas containing a large number of microorganisms, the service life of the mask filter material will be very short, and it is usually changed once or every day.

Some electric masks are based on the structure of ordinary masks, using motors instead of human inhalation, and using filter cloth with better filtering effect and poor air permeability. This kind of mask solves the problem of hard breathing of ordinary masks, but if the battery is insufficient or the motor fails, it will cause a greater risk of airtight suffocation. At the same time, the use of filter cloth to filter general particulate matter cannot effectively prevent viruses. Because this kind of filter cloth is relatively dense, it is impossible to communicate with the outside world after wearing a mask.

In places such as hospitals and scientific research laboratories, there may be a danger of pathogenic viruses and their attachments suspended in the air. For some people with poor physique or patients, a small amount of virus may also pose a greater threat when exposed to polluted air.

The search found that the patent number 201080041291.9, the utility model patent with the publication number CN 102781520B, describes an electric respirator, which is mainly suitable for the protection of the respiratory tract in toxic gas environments such as dust and exhaust gas, and cannot defend against fine viruses. In addition, this utility model has disadvantages such as complex structure, high cost and insufficient comfort.

To sum up, it is now necessary to develop a breathing device that can not only protect against dust and particulate matter, but also serve the purpose of anti-virus.

detailed description

Embodiment one

The head-mounted anti-virus respirator of the present embodiment has a structure as shown in Figures 1-4: it includes a breathing mask 2 and a breathing mask fixing mechanism 1; the breathing mask 2 is a structure suitable for surrounding the user's mouth, nose and chin One side of the respirator is provided with a ventilation port 2-1, and the respirator fixing mechanism 1 includes an anti-virus filter, an air duct and a clip rib matching the shape of the respirator; the respirator 2 is inserted into the Inside the clamping rib, its vent 2-1 communicates with the antivirus filter through the air duct. Air vent 2-1 accepts the clean air that air duct sends over. On the outer edge of the opposite side, there is an open air exhaust port 2-2 at a position similar to the height of the air vent 2-1 or slightly higher or slightly lower. The air outlet 2-2 area of the respirator is 2/3 of the area of the vent 2-1, which can maintain a certain slight positive pressure in the respirator and play a better protective effect.

The symmetrical setting of the air vent 2-1 and the air exhaust port 2-2 makes the internal airflow present the characteristics of a stable laminar flow from the mouth and nose, effectively avoiding the intrusion of external pollutants and viruses. The characteristic of laminar flow is that the airflow is relatively parallel, layer by layer, and moves steadily from the inlet to the outlet. It is obviously different from the scattered flow of ordinary masks or electric masks (the airflow is from the surrounding to the center, or in the opposite direction), and it is even more different from the vortex flow blown by the fan rotation or the turbulent flow with no obvious rules. Laminar flow can ensure that the rotation and collision of the airflow are minimized, and the pollutants or viruses in the exhaust outlet will not be brought to the breathing place of the mouth and nose by the partial reverse airflow.

At the same time, the open air outlet 2-2 design prevents the risk of suffocation under extreme use conditions (including battery exhaustion, fan damage, etc.), and is suitable for slow-moving elderly and children. Since the wearer's voice will come out from the exhaust vent along with the laminar air, it can play the role of talking.

The breathing mask fixing mechanism 1 is a U-shaped structure centered on the clamping ribs, both sides are bent backwards and extend to the outside of the user's neck. The shape of the respirator matches the shape of the mouth and nose of a person; its edge is bent and extended inwardly to form a circle of card slots; the respirator is inserted into the clip ribs of the respirator fixing mechanism through the card slots . The breathing mask is made of soft silicone material; it can also be taken off for cleaning or replacement when necessary, which is convenient and quick to assemble and disassemble.

One side of the breathing mask fixing mechanism 1 is provided with an air inlet 1-1; the anti-virus respirator is buckled inside the air inlet 1-1. It not only has the effect of being impermeable to viruses, but also can achieve the effect of a user replaceable filter.

The utility model also includes a centrifugal fan arranged in the air inlet 1-1 to provide stable laminar flow for the breathing mask. Therefore, the breathing mask does not need to be in close contact with the user's head and face, which is also a great convenience in use. The air enters from the air outlet of the filter, passes through the fan and the air duct after being filtered, enters the side of the front respirator, then passes through the breathing area in a laminar flow, and is discharged from the air outlet on the other side of the respirator.

The air volume of the respirator, the user can directly adjust the centrifugal fan. In order to ensure the breathing strength of users of all ages, the maximum air volume provided by the respirator should not be less than 80ml/min.

The technology does not limit the type of fan used. However, in order to cooperate with the use of the anti-virus filter and achieve the design effect, a centrifugal fan should be used. At the same time, attention should be paid to reducing noise and reducing interference to users.

The breathing mask fixing mechanism 1 is also equipped with a power supply, a controller, a display screen 4 connected with the controller signal, and two air quality sensors. The power supply, controller, display screen 4 and one of the air quality sensors are installed on the other side of the non-air duct of the respirator fixing mechanism 1, symmetrically installed with the anti-virus respirator; detect the air quality in the external environment. The setting of this side part is mainly because of maintaining balance with the weight of the other side and the limitation of space, and is not necessarily separated from the other side in principle. The primary role of the battery is to power the fan, as well as power the user interface or optional air quality sensor. For convenience, the respirator uses rechargeable batteries.

In order to monitor the air quality in the respirator, another air quality sensor can be installed in the air duct of the respirator, that is, from the back of the virus filter to the front of the respirator, to monitor in real time whether the air is purified. If the air is not cleaned, the user can be prompted to check the condition of the respirator or replace the anti-virus filter.

As shown in Figure 5: the values of the two air quality sensors and the status of the respirator itself can be displayed on the display screen of the respirator. It can also be transmitted to the mobile phone through bluetooth or wifi and other transmission methods for users or guardians to view, so as to protect and collect data at the same time.

An elastic adjustable headband 3 is installed between the two side ends of the breathing mask fixing mechanism 1 . It can also be worn in two ways by connecting the headband. The wearing method of using the headband is to fix the respirator on the top or side rear of the head with the headband. Using the neck strap, the respirator can be fastened to the neck with a snap. It can be automatically adjusted for users with different head sizes.

In addition to the above embodiments, the utility model can also have other implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the utility model.
