Description

Technical Field

[0001] The present application relates to the technical field of fire masks, and in particular to a fire mask with a rescue function. Background Art

[0002] According to statistics, up to 80% of people who died in fires died of suffocation due to inhalation of toxic smoke. By wearing a fire mask, toxic smoke can be filtered out, thereby increasing people's survival rate when escaping from a fire.

[0003] When escaping from a fire, people who are not familiar with the escape route are very likely to be trapped indoors. Traditional fire masks have relatively simple functions and can often only filter out smoke and dust. Blind calls for help (shouting) by people often fail to achieve the desired effect, which not only wastes physical energy but also easily delays precious rescue time. In order to reasonably improve this problem, this application proposes a fire mask with a help-calling function. Summary of the Invention

[0004] The purpose of this application is to solve the technical problem that when escaping from a fire, people who are not familiar with the escape route are easily trapped indoors. The functions of traditional fire masks are relatively simple and can only filter smoke and dust. People blindly call for help, which often fails to achieve the purpose of calling for help, not only wasting physical energy but also easily delaying precious rescue time. This application provides a fire mask with a call for help function.

[0005] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0006] A fire mask with a rescue function, comprising:

[0007] A mask portion, used to cover the mouth and nose, with fixing portions provided at both ends of the mask portion, through which the mask portion is worn;

[0008] Two ventilation holes are symmetrically arranged on the mask portion and are equipped with filters for covering the ventilation holes;

[0009] The sound-generating mechanism is arranged on the mask portion, and a distress signal can be sent out through the sound-generating mechanism.

[0010] Furthermore, the sound-generating mechanism includes an air outlet pipe installed on the mask part, the air inlet end of the air outlet pipe passes through the inner side of the mask part and is connected to the mouthpiece, a fixing plate that cuts off the cavity diameter of the air outlet pipe is connected to the air outlet pipe, a whistle device is fixedly connected to the fixing plate, and the air inlet end and the air outlet end of the whistle device are respectively located on the back sides of the fixing plate.

[0011] Furthermore, a fixed block is connected to the outside of the mask part, a sound amplification groove is opened on the fixed block, and a breathable cover is equipped for covering the sound amplification groove. The sound amplification groove is connected to the outlet end of the exhaust pipe, and the inner diameter of the sound amplification groove gradually decreases from the fixed block toward the mask part.

[0012] Furthermore, the outer side of the oral mouthpiece is constructed with an arc-shaped plate.

[0013] Furthermore, a one-way air valve is installed in the oral mouthpiece.

[0014] Furthermore, the mask portion includes a silicone inner layer and a rubber outer layer that are connected to each other, and the mouthpiece is tough and in close contact with the silicone inner layer.

[0015] Furthermore, the fixing portion includes ear clips installed at both ends of the rubber outer layer, and the rubber outer layer is equipped with an overlapping portion that contacts and overlaps with the user's lower jaw.

[0016] Furthermore, the filter includes a mounting shell connected to the mask portion, a strip hole is opened on the outside of the mounting shell, an activated carbon layer is arranged inside the mounting shell, a smoke filter membrane is arranged inside the activated carbon layer, and the air vents are covered.

[0017] The beneficial effects of this application are as follows:

[0018] This application cleverly combines the filter, the sound-generating mechanism and the mask part together. When the user is trapped, the sound-generating mechanism can send a distress signal, which not only enables rescuers to quickly find the user, but also saves the user's physical strength, making it easier to escape from the fire scene later. It is very practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0025] like Figures 1-4 As shown, an embodiment of the present application provides a fire mask with a rescue function, comprising:

[0026] The mask portion 1 is not breathable and is used to cover the mouth and nose. Both ends of the mask portion 1 are provided with fixing portions 2. The mask portion 1 is worn through the fixing portions 2. When the mask portion 1 fits the user's face, it can be fixed by the fixing portions 2 and cover the user's mouth and nose.

[0027] Two air holes 3, both in strip shape, are symmetrically arranged on the mask portion 1, through which air can flow. A filter 4 is provided to cover the air holes 3. The filter 4 can filter out toxic fumes in the air, so that pure filtered air can be obtained every time you inhale.

[0028] The sound-generating mechanism 5 is provided on the mask portion 1 and can emit a distress signal through the sound-generating mechanism 5. The distress signal is more easily received by rescuers than the user's shouting.

[0029] This application cleverly combines the filter 4, the sound-generating mechanism 5 and the mask part 1 together. When the user is trapped, the sound-generating mechanism 5 can send a distress signal, which not only enables rescue personnel to quickly find the user, but also saves the user's physical strength, making it easier to escape from the fire scene later, and is very practical.

[0030] like Figure 2-Figure 4As shown, in some embodiments, the sound-generating mechanism 5 includes an air outlet pipe 501 mounted on the mask portion 1, the air inlet end of the air outlet pipe 501 passes through the inner side of the mask portion 1 and is connected to the oral mouthpiece 502. The air outlet pipe 501 is close to the middle of the mask portion 1. When the user holds the oral mouthpiece 502 in his mouth, the lung air can be blown out from the air outlet pipe 501. A fixing plate 503 that cuts off the cavity diameter of the air outlet pipe 501 is connected to the inside of the air outlet pipe 501, and a whistle device 504 is fixedly connected to the fixing plate 503. The whistle device 504 is an existing single-tube whistle, and the air inlet end and the air outlet end of the whistle device 504 are respectively located on the back side of the fixed plate 503, that is, the air inlet end and the air outlet end of the whistle device 504 are close to the air inlet end and the air outlet end of the outlet pipe 501, respectively. The outside air enters the mask part 1 through the filter 4 and the air vent 3 and is inhaled by the user's nose. When the user exhales, the air passes through the whistle device 504 and emits a sharp whistle, which makes it convenient for rescue personnel to quickly find the user.

[0031] like Figures 1-4 As shown, in some embodiments, a fixing block 6 is connected to the outside of the mask portion 1. The fixing block 6 is made of ABS plastic and is close to the middle of the mask portion 1. A sound amplification groove 7 is opened on the fixing block 6, and a breathable cover 8 is provided for covering the sound amplification groove 7. The breathable cover 8 is in the shape of a fence, which can prevent debris from entering the sound amplification groove 7. The sound amplification groove 7 is connected to the outlet end of the air outlet pipe 501. The inner diameter of the sound amplification groove 7 gradually decreases from the fixing block 6 toward the mask portion 1. The air outlet pipe 501 is connected to the end with the smaller diameter in the sound amplification groove 7. The structure here is similar to a loudspeaker. When sound waves pass through the sound amplification groove 7, they will be refracted at the wall of the sound amplification groove 7, thereby increasing the volume of the whistle device 504.

[0032] like Figure 2-Figure 4 As shown, in some embodiments, the outer side of the oral mouthpiece 502 is constructed with a curved plate 9. When the user holds the oral mouthpiece 502 in his mouth, the curved plate 9 can contact the inside of the user's teeth and is not easy to fall off, which greatly ensures the safety of the user and the functionality of the product.

[0033] like Figure 4 As shown, in some embodiments, a one-way air valve 10 is installed in the mouthpiece 502. The one-way air valve 10 is a silicone duckbill one-way valve. When avoiding a fire, it is often necessary to run. Some users will involuntarily breathe deeply during intense exercise. The one-way air valve 10 can prevent the user from inhaling harmful gases into the lungs.

[0034] like Figure 1 and Figure 2As shown, in some embodiments, the mask portion 1 includes a silicone inner layer 101 and a rubber outer layer 102 that are interconnected. The silicone inner layer 101 fits the user's face to reduce the entry of air. The rubber outer layer 102 is tough and can also play a certain shaping role to prevent the silicone inner layer 101 from deforming. The oral mouthpiece 502 is tough and is made of food-grade silicone and is close to the silicone inner layer 101. It should be specifically noted here that the axis of the air outlet pipe 501 is perpendicular to the axis of the sound amplification groove 7, that is, the air outlet pipe 501 is close to the silicone inner layer 101. This design makes the product foldable, and after folding, the oral mouthpiece 502 and the air outlet pipe 501 will be wrapped by the middle part of the silicone inner layer 101. Under the cooperation of the rubber outer layer 102 and the fixing block 6, the oral mouthpiece 502 and the air outlet pipe 501 are not easily squeezed, so that it can be put into a carry-on bag after folding.

[0035] like Figure 1 and Figure 2 As shown, in some embodiments, the fixing portion 2 includes ear clips 201 installed at both ends of the rubber outer layer 102, as shown in FIG. Figure 3 As shown, there is an angle between the ear clip 201 and the end of the rubber outer layer 102, and the user's ear can be stuck in the angle. The rubber outer layer 102 is cooperated with a lap portion 202, which is constructed at the bottom of the rubber outer layer 102 and overlaps with the user's lower jaw. After wearing, the ear clip 201 and the lap portion 202 are respectively fixed to the user's ear and lower jaw. By adopting the new ear clip 201 wearing method, it is easy to wear and can shorten the time wasted when escaping.

[0036] like Figure 1 and Figure 2 As shown, in some embodiments, the filter 4 includes a mounting shell 401 connected to the mask portion 1, and a strip hole 402 is opened on the outside of the mounting shell 401, and air can enter the mounting shell 401 through the strip hole 402. An activated carbon layer 403 is provided in the mounting shell 401, and the activated carbon layer 403 is composed of activated carbon powder wrapped in non-woven fabric. A smoke filter membrane 404 is provided on the inside of the activated carbon layer 403, and covers the air permeability 3, so as to filter toxic smoke in the air.

[0037] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
