Description

Technical Field

[0001] The invention relates to a face mask, in particular to an antibacterial eye protection face mask. Background Art

[0002] Most masks on the market now have improved sealing in order to better protect against cold and warmth and prevent dust and bacteria, but this not only reduces the ventilation performance of the mask, but also increases the breathing resistance. Moreover, these masks have only one cavity, which causes the exhaled gas and the inhaled gas to mix, which greatly reduces the amount of oxygen inhaled by the wearer each time he breathes, which not only reduces the comfort but also affects the health. If the wearer suffers from certain bacterial or viral respiratory diseases, he needs treatment. If he wears a mask, he may even be repeatedly infected and affect his recovery. Therefore, doctors believe that special groups such as patients with respiratory diseases, people with respiratory sensitivity, heart disease patients, hypertensive patients, pregnant women, etc. are not suitable for wearing masks. Even ordinary healthy people are not suitable for wearing masks when exercising. Some people have also invented some masks with breathing valves. Although they reduce the exhaust resistance compared to ordinary masks, they do not fundamentally improve the mixing of exhaled and inhaled gases, and are inconvenient to clean and not suitable for repeated use.

[0003] A convenient breathing mask is disclosed in a patent document with application number 201510586552.X in China and publication date 2015.12.9. The convenient breathing mask includes a mask body, a left ear rope sleeve and a right ear rope sleeve are fixed on both sides of the mask body, an inner cup is arranged on the inner side of the mask body, filter cotton is installed in the inner cup, the filter cotton is connected to an exhaust pipe, a fixing nut is arranged on the exhaust pipe, the fixing nut is fixed at the center of the mask body, the exhaust pipe extends out of the mask body, and an exhaust pipe is arranged at the outer end of the exhaust pipe.

[0004] The inner cup has one end of the air intake pipe fixed to one side of the inner cup, the air intake valve is installed in the bottom of the air intake pipe, the outer end of the air intake pipe extends out of the outer side of the mask body, and the outer end of the air intake pipe has activated carbon built in. The air intake valve uses a one-way valve that can only enter but not exit, and the exhaust valve uses a one-way valve that can only exit but not enter.

[0005] However, when the convenient breathing mask is exhausted, the gas must first pass through the filter cotton and the exhaust pipe before reaching the exhaust valve for exhaust, and the distance between the exhaust valve and the inner cup is long; the exhausted gas stays in the exhaust pipe for a long time, which easily causes the exhausted gas to be stored in the exhaust pipe; at the same time, the air inlet pipe of the mask is connected to the exhaust pipe, which will cause the gas that stays in the exhaust pipe and is not discharged in time to be inhaled into the human body during inhalation, and the dust in the air directly enters the air inlet filter sheet, shortening the service life of the filter cotton; carbon dioxide is inhaled when inhaling, which will result in less oxygen inhaled during inhalation, and further causing discomfort to the human body; at the same time, the mask is only provided with one air inlet pipe, so the oxygen inhaled during inhalation is effective; thus, the use scenarios of the mask are limited, and wearing the mask for physical labor will cause breathing problems.

[0006] In addition, the exhaust ports of existing masks are basically straight-exhaust type, so that droplets produced by human exhalation can easily enter the air. For diseases that can be transmitted through the conjunctiva, ordinary masks cannot protect the conjunctiva well, and there is a risk of infection. Summary of the invention

[0007] The present invention provides an antibacterial eye protection mask. By utilizing the structure of the present invention, the path and length of the air outlet are changed, and the gas coming out of the one-way valve is buffered through the air outlet buffer cavity, and then discharged into the air after being filtered by the air outlet filter device, and the eyes are protected by the goggles to prevent viruses or bacteria from entering the eyes.

An air inlet channel 25 is provided on the mounting member 21 outside the air outlet channel. In this embodiment, the air inlet channel 25 is provided with a There are three, a second mounting column 28a is provided in the middle of the air inlet channel 25, a second rib plate 28 is provided on the air inlet channel 25 extending from the second mounting column to the edge of the air inlet channel 25, the second rib plate 28 is connected to the mounting member 21, and an air inlet check valve 281 is provided on the second mounting column 28a behind the second rib plate 28; a reinforcing rib 26 is provided on the mounting member 21 between adjacent air inlet channels 25; a convex ring 22 extends from the mounting plate at the edge of the air outlet channel 24 toward the housing 1, and the convex ring 22 extends into the air outlet buffer chamber 181; the stop flange 23 first extends from the mounting member 21 away from the mask 3 and then extends outward, and the mounting groove 29 is recessed along the inner side of the stop flange 23 toward the mounting member 21. When the fixing device 2 is installed, the mounting member 21 passes through the mask installation window 311, and the stop flange 23 is stopped by the stop portion 3112. The air intake filter 4 is sleeved on the convex ring 22 , and the air intake filter 4 is located in the installation groove 29 .

[0045] In this embodiment, if Fig.12 As shown, when the housing 1 is installed, the flange 13 on the housing 1 is pressed onto the air inlet filter 4, forming an air inlet 161 between the housing 1 and the fixing device.

[0046] like Figure 4 , Figure 8 and Fig. 9 As shown, the mask is a nano-silicone flexible mask. With the nano-silicone flexible mask, the nano material can purify the air, and the nano-silicone flexible mask has good high temperature resistance. Therefore, the mask can be disinfected multiple times by high temperature. In this way, the mask can be reused, thereby reducing the cost, and the flexible mask fits the face more closely.

[0047] During installation, the goggles 331 are located in the goggles installation window and the edge of the goggles 331 is clamped into the installation groove 3121. The positioning column 3311 on the goggles 331 passes through the positioning hole 3122, and the positioning column extends into the hole 58. The positioning rib 3312 on the goggles 331 is located on the inner side of the edge of the installation groove. The positioning rib 3312 is used to block the edge of the goggles installation window, and the positioning column 3311 is used to position the goggles. Since the mask is flexible, the installation of the goggles is convenient and quick. After the goggles are installed, the shell 5 is installed on the mask 3, and then the fixing device 2 is pressed and installed on the mask 3. After installation, the convex ring 22 protrudes from the mask 3; then the air intake filter 4 is sleeved on the convex ring 22; finally, the shell 1 is clamped to the hook of the clamping member through the clamping hole 15 to complete the installation of the antibacterial eye mask.

[0048] When the antibacterial eye protection mask of the above structure is used, the face-fitting part is attached to the human face, and the eye protection part is attached to the human eye. The outside air enters the air inlet cavity from the air inlet, and the air in the air inlet cavity is filtered by the air inlet filter, and then enters the mask through the one-way valve of the air inlet channel. The exhaled gas of the human body enters the air outlet buffer cavity through the air outlet channel and the air outlet one-way valve, and the exhaled gas is buffered and retained by the air outlet buffer cavity, and then filtered by the air outlet filter device and enters the air under the guidance of the air outlet guide channel. With this structure, the exhaled gas does not return to the air inlet cavity after passing through the air outlet one-way valve, but is then buffered by the air outlet buffer cavity, and finally filtered by the air outlet filter device, and then the exhaled gas is redirected by the air outlet guide channel and the air outlet channel is extended. In this way, under the action of the one-way valve, not only is the exhaled gas prevented from flowing back to protect the user, but also the exhaled gas is buffered and filtered, and the path and length of the exhaled gas are changed, thereby reducing the droplets in the exhaled gas from entering the air, thereby effectively protecting other people. Therefore, the mask is healthy and safe to use, and has good protective performance.

[0049] Since a separation plate is provided, the air inlet cavity and the air outlet buffer guide channel can be effectively separated, and the air outlet channel extends into the separation plate, so that the exhaled gas and the inhaled gas can be further prevented from mixing in the air inlet cavity and the air outlet buffer guide channel, and the safety and protection performance can be further improved. Since a lower separation plate is provided, the exhaled gas can be redirected and the path can be extended through the lower separation plate. Since a flange is provided, the air inlet filter can be pressed and fixed, and at the same time, the outside air can be guaranteed to enter the air inlet cavity through the air inlet. By providing a convex ring, and the convex ring extends into the air outlet buffer cavity, the gas exhaled from the cavity enters the air outlet buffer cavity through the one-way valve, so that the exhaled gas is prevented from entering the air inlet cavity, and the unsafe and unhealthy phenomenon caused by the repeated use of the exhaled gas of the human body is avoided. The structure of the flange and the mounting groove is used to prevent the mask from being easily detached from the fixing device. Since the air inlet filter is sleeved on the convex ring, and the convex ring extends into the air outlet buffer cavity, the gas in the air inlet cavity can reliably enter the cavity through the air inlet filter. Since the air inlet groove is provided, it is convenient for air to enter the air inlet cavity. Through the matching connection of the clamping piece and the clamping hole, it is convenient to install and disassemble the shell, so it is convenient to clean the shell, the mask body, etc., and it is convenient to use the mask multiple times, and it has good safety performance after cleaning and reuse.

[0050] Since an air intake one-way valve is provided, when a person exhales, the gas will not enter the air intake filter and the air intake cavity. This can effectively avoid contaminating the air intake filter and effectively avoid the formation of water vapor on the air intake filter. On the one hand, it can keep the air intake filter clean for a longer time and increase the service life of the air intake filter. On the other hand, it can avoid the influence of air intake resistance caused by water vapor generated on the air intake filter.

[0051] Since the air inlet of the present invention is located at the side, that is, the air inlet is formed at the side of the shell or / and between the shell and the fixing device, this can prevent the incoming air from directly rushing into the shell from the front of the shell, and can effectively reduce the dust in the air directly entering the air intake filter, thereby increasing the service life of the air intake filter.
