Description

Technical Field

[0001] The present invention belongs to the technical field of mask products, and particularly relates to a wettable emergency water-filled mask capable of preventing smoke and a certain degree of poisonous gas. Background Art

[0002] In many fire scenes or cases of smoke and poisonous gas leakage, the protective devices commonly used are activated carbon masks. However, activated carbon masks are costly and not conducive to popularization. Many families or public places do not prepare a large number of activated carbon masks. In the event of the above-mentioned emergencies, many people will inevitably be unable to use activated carbon masks and suffer injuries. Moreover, even when using this type of mask, the existing masks are difficult to effectively block smoke.

[0003] As for professional smoke and poison gas masks, their popularity is insufficient, and it is difficult to prepare and wear them in daily life. In addition, the current masks have a single function and do not have a lighting function. In smoke, people's vision is usually blocked, which is not conducive to quick escape. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a convenient-to-use emergency water-filled mask.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] An emergency water-filled mask includes a mask body. Ear straps are provided on the mask body. The mask body has a skin-friendly layer and an outer surface layer. A water storage cavity is provided between the skin-friendly layer and the outer surface layer. The water storage cavity is filled with a liquid. The middle part of the water storage cavity is a hollow area. One side surface of the water storage cavity is fixedly connected to the surface of the skin-friendly layer, and the other side surface is fixedly connected to the surface of the outer surface layer. An assembly cavity is formed among the skin-friendly layer, the water storage cavity and the outer surface layer. An outlet valve body assembly is provided in the assembly cavity. The outlet valve body assembly is connected to the water storage cavity. Pressing the outlet valve body assembly from the outer surface layer of the mask body causes the water in the water storage cavity to flow into the outlet valve body assembly and then penetrate and wet the outer surface layer and the skin-friendly layer.

[0007] The outlet valve body assembly includes a valve seat, a valve core, and a pressing member. A receiving hole is provided in the valve seat. The lower part of the pressing member is inserted into the receiving hole in the valve seat and is in a tight fit. A water inlet channel is installed on the side wall of the valve seat. One end of the water inlet channel is connected and communicated with the water storage cavity, and the other end of the water inlet channel is communicated with the receiving hole. The upper end of the pressing member extends out of the outer surface layer and is exposed outside the outer surface layer. When the pressing member is not pressed down, the valve core seals the water inlet channel so that the water in the water storage cavity does not flow into the receiving hole of the valve seat. After pressing down the pressing member, the valve core no longer completely blocks the water inlet channel, allowing the water in the water storage cavity to flow into the receiving hole.

[0008] The valve core is a stepped shaft with a lower sealing part and an upper connecting rod. The lower sealing part is installed in the accommodating hole and forms a sealed state with the accommodating hole. The pressing part is connected to the upper connecting rod, and the diameter of the upper connecting rod is smaller than that of the lower sealing part.

[0009] A sealing ring is provided on the side of the lower sealing part of the valve core, and the sealing ring contacts and seals the inner wall of the accommodating hole of the valve seat.

[0010] Several water outlet channels are provided on the upper end surface of the valve seat.

[0011] The pressing part is a thimble, which is inserted into the upper connecting rod of the valve core and connected and fixed. The upper end of the thimble is exposed outside the outer layer.

[0012] The valve seat is installed on the cap, and the cap is fitted and connected to the skin-friendly layer of the mask body.

[0013] The water inlet channel is integrally formed on the valve seat.

[0014] The water storage cavity is an annular water storage bag.

[0015] A power contact switch is installed at the bottom of the accommodating hole of the valve seat. The power contact switch is connected to the battery. An LED lamp is provided on the outer layer of the mask body. The LED lamp is connected to the battery and the power contact switch through a circuit. When the pressing part is pressed down, it will press against the power contact switch, causing the power contact switch, the battery, and the LED lamp to form a closed conduction circuit, making the LED lamp light up.

[0016] By setting the water storage bag and the LED lamp in the present invention, when the water outlet valve body assembly is pressed, the water in the water storage cavity overflows to wet the outer layer and the skin-friendly layer, which can effectively block the smoke and poisonous gas outside, prevent the smoke and poisonous gas from entering the nose and mouth, and at the same time make the LED lamp light up, increasing the visibility of the user in the smoke. The light can also serve as a warning to the rescue personnel, winning time for the user to escape. It is convenient to use and has a low cost. Brief Description of the Drawings

Detailed implementation manners

[0022] To further understand the features, technical means, specific purposes, and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0023] As shown in the attached Figures 1-4 figure, the present invention provides an emergency water - filling mask, which includes a mask body. An ear strap 1 is provided on the mask body. The mask body has a skin - contacting layer 21 and an outer surface layer 22. A water storage cavity 13 is provided between the skin - contacting layer 21 and the outer surface layer 22. The water storage cavity 13 is filled with a liquid. The middle part of the water storage cavity 13 is a hollow area 14. One side surface of the water storage cavity 13 is in fitting connection with the surface of the skin - contacting layer 21, and the other side surface is in fitting connection with the outer surface. An assembly cavity is formed among the skin - contacting layer, the water storage cavity, and the outer surface layer. A water outlet valve body assembly 15 is provided in the assembly cavity. The water outlet valve body assembly 15 is connected to the water storage cavity 13. Pressing the water outlet valve body assembly from the outer surface layer of the mask body enables the liquid in the water storage cavity to flow into the water outlet valve body assembly and then penetrate and wet the outer surface layer and the skin - contacting layer. The water storage cavity is an annular water storage bag made of waterproof material. The liquid filled inside can be clear water or other liquids that can prevent poison and do not cause harm to the human body. The entire water storage cavity is sealed to ensure that the internal liquid will not overflow when not punctured externally. The middle hollow area does not affect normal breathing.

[0024] The water outlet valve body assembly includes a valve seat 7, a valve core 10, and a pressing member 11. A receiving hole 8 is provided in the valve seat 7. The lower part of the pressing member 11 is inserted into the receiving hole 8 in the valve seat 7 and is in tight fit. A water inlet channel 9 is connected to the side wall of the valve seat 7. One end of the water inlet channel 9 is connected and communicated with the water storage cavity 13, and the other end of the water inlet channel 9 is communicated with the receiving hole 8. The upper end of the pressing member 11 extends out of the outer surface layer 22 and is exposed outside the outer surface layer 22. The connection part of the pressing member 11 and the outer surface layer 22 has a sealing treatment. Since the overall mask is relatively thin, only a small force is required to press down the pressing member. The pressing member drives the valve core to move along the receiving hole of the valve seat. When the pressing member is not pressed down, the valve core seals the water inlet channel so that the water in the water storage cavity does not flow into the receiving hole of the valve seat. After pressing down the pressing member, the valve core no longer completely blocks the water inlet channel, enabling the water in the water storage cavity to flow into the receiving hole. The water inlet channel and the water storage bag are in a normally - open state, and the flow of water in the water inlet channel into the receiving hole of the valve seat is controlled by the valve core.

[0025] The spool 10 is in the shape of a stepped shaft with a lower sealing portion 101 and an upper connecting rod 102. The lower sealing portion 101 is installed in the receiving hole 8 and forms a sealed state with the receiving hole 8. The pressing member 11 is connected to the upper connecting rod 102, and the diameter of the upper connecting rod 102 is smaller than that of the lower sealing portion 101. A sealing ring is provided on the side surface of the lower sealing portion 101 of the spool 10, and the sealing ring contacts and seals the inner side wall of the receiving hole of the valve seat. By setting the spool in the shape of a stepped shaft, there is a gap between the upper connecting rod portion and the receiving hole of the spool, while the lower sealing portion forms a sealed state with the receiving hole, so that the side wall of the lower sealing portion blocks the port of the water inlet passage on the side wall of the valve seat, preventing the water in the water inlet passage from flowing into the receiving hole. By applying pressure to the pressing member, the lower sealing portion is driven to move and change its position, so that it no longer completely blocks the port of the water inlet passage, and the liquid can flow into the receiving hole through the water inlet passage.

[0026] A plurality of water outlet passages 12 are provided on the upper end surface of the valve seat 7. In this embodiment, four water outlet passages are evenly arranged on the upper end surface of the valve seat. After the liquid in the receiving hole continuously increases, it overflows outward through the water outlet passages, thereby wetting the skin-friendly layer and the outer layer.

[0027] The pressing member 11 is a thimble, which is inserted into and fixedly connected to the upper connecting rod of the spool. The upper end of the thimble is exposed outside the outer layer, and the upper end of the pressing member 11 has a pressing cap 4 for convenient operation.

[0028] The valve seat 7 is installed on the cap 5, and the cap 5 is adhesively connected to the skin-friendly layer 21 of the mask body. Corresponding mounting holes can be provided on the side wall of the valve seat. The cap has a side wall that can be snapped into the mounting holes for installation and is also convenient for disassembly.

[0029] The water inlet passage 9 is integrally formed on the valve seat 7. The water inlet passage can be flat or in the shape of a circular pipe. It is inserted into the water storage bag, and the connection position with the water storage bag is sealed, such as by applying sealant or other types of sealing treatment, to ensure that water does not overflow from the connection position.

[0030] In addition, a power contact switch 16 is installed at the bottom of the receiving hole 8 of the valve seat 7. The power contact switch 16 is connected to a battery. An LED lamp 3 is provided on the outer surface layer of the mask body. The LED lamp is connected to the battery and the power contact switch through a circuit. When the pressing member 11 is pressed down, the valve core 10 will press against the power contact switch 16, causing the power contact switch, the battery, and the LED lamp to form a closed conduction circuit, making the LED lamp emit light. The power contact switch is a well-known accessory with two contact ends. One contact end is connected to the battery, and the other contact end is connected to the LED lamp. The LED lamp is also connected to the battery. When the power contact switch is not under pressure, it remains disconnected. After the valve core is pressed down by the pressure, the valve core will press the power contact switch, causing the power contact switch to conduct, so that the LED lamp is powered on and emits light, achieving the functions of supplying water and power to the mask simultaneously. At the same time, it provides a better visual environment and a moist mask to block smoke and poison. Corresponding wire holes can be provided on the side wall of the valve seat to facilitate the connection of the circuit.

[0031] The present invention uses a conventional protective mask and makes improvements on the basis of the conventional protective mask by setting a water storage bag. The valve core completely seals and plugs the port of the water inlet channel, so that the liquid in the water storage bag will not flow into the receiving hole of the valve seat through the water inlet channel. When encountering an emergency such as a fire, take out the mask and press the thimble. The thimble presses down the valve core, causing the valve core to move and change its position. As the valve core moves, the port of the water inlet channel is gradually exposed. The lower sealing part of the valve core no longer completely plugs the port of the water inlet channel. The liquid in the water storage bag flows into the receiving hole through the water inlet channel and moves to the bottom position of the receiving hole along with the valve core. At this time, it is completely separated from the port of the water inlet channel, and the liquid in the water storage bag continuously flows into the receiving hole through the water inlet channel. As the liquid increases, the liquid overflows upward, and the liquid will overflow from the water outlet channel of the valve seat, thereby wetting the skin-attached layer and the outer surface layer. Wearing it by a person can effectively prevent smoke and poison gas. In order to make the liquid wet the skin-attached layer and the outer surface layer faster, the water storage bag can be squeezed hard to make the water flow into the receiving hole of the valve seat more quickly.

[0032] In addition, when the valve core moves to the bottom of the receiving hole, it will trigger the power contact switch, causing the LED lamp to be powered on and emit light, while providing a better visual environment and emitting an alarm display outward.

[0033] It should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
