Description

Technical Field

[0001] This utility model relates to the field of filter masks, specifically a dual-filter waterproof and dustproof mask device. Background Technology

[0002] Dual-filter masks are advanced personal protective equipment primarily used to protect wearers from harmful gases, particulate matter, liquids, and other contaminants. Compared to single-filter masks, dual-filter systems offer a higher level of protection and are suitable for various working environments and applications. Through their dual-filtration design, dual-filter masks provide a higher level of protection, effectively reducing health risks. They are an indispensable tool in industrial safety, public health, and personal protection. Proper maintenance is essential to ensure their effectiveness and lifespan.

[0003] During the use and storage of dual-filter mask devices, special attention needs to be paid to moisture prevention. This is because the filter material inside the dual filter is very prone to deterioration in a humid environment, which directly affects the filtration effect of the mask. The performance of the filter material is closely related to its physical state. A humid environment will cause the filter material to absorb water and soften, thereby reducing its ability to capture fine particles and harmful gases. Once the filter material loses its effectiveness, it will not only expose the wearer to potentially harmful substances, but may also lead to health risks. For this reason, we have proposed a dual-filter waterproof and dustproof mask device. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a dual-filtration waterproof and dustproof mask device, which has the following beneficial effects:

[0015] 1. This dual-filter waterproof and dustproof mask device adds a second waterproof structure at the point where the dual filter of the mask's inhalation valve connects to the outside environment, and increases the air intake folding distance between the air intake channels to filter water vapor, reduce water vapor entering the dual filter, and extend the service life of the dual filter. This not only maintains the good performance of the filter and ensures the safety of the wearer, but also reduces the economic burden caused by frequent filter replacement and improves the overall efficiency of use.

[0016] 2. This dual-filter waterproof and dustproof mask device adds a first waterproof structure at the point where the dual filters at the mask's air inlet come into contact with the face. When a person breathes, water vapor is produced. A large amount of water vapor will be discharged from the mask's exhalation valve, but a small amount will enter the dual filters, causing them to become damp. The second waterproof structure can effectively prevent the water vapor exhaled by the human body from contacting the dual filters. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 A dual-filtration waterproof and dustproof mask device includes a mask 1, a transparent frame 2, a headband 3, an exhalation component 4, and an air intake component. The mask 1 is provided with a transparent frame 2, and the headband 3 is fixedly connected to both sides of the mask 1. The mask 1 is provided with an exhalation component 4, which is located below the transparent frame 2. Two air intake components are provided on the mask 1 and on both sides of the exhalation component 4, symmetrical about the exhalation component 4.

[0026] Furthermore, two symmetrical connecting tubes 10 are fixedly connected through the mask 1. The two connecting tubes 10 are symmetrical about the exhalation component 4. A threaded groove 11 is opened on the end of the connecting tube 10 away from the mask 1. The connecting tube 10 is used to connect the mask 1 and the air intake component. The threaded groove 11 is used to connect with the air intake component by thread.

[0027] Furthermore, the air intake assembly includes a first waterproof structure, a dual filter 8, and a second waterproof structure. The first waterproof structure is threadedly connected to the connecting pipe 10 on the mask 1. The first waterproof structure has a dual filter 8 inside at the end facing away from the mask 1. The end of the first waterproof structure with the dual filter 8 is fixedly connected to the second waterproof structure. The first waterproof structure and the second waterproof structure provide moisture protection for the dual filter 8 in two directions.

[0028] Furthermore, the first waterproof structure includes an externally threaded connecting pipe 7, a second connecting pipe 17, a tubular support 6, and a water-absorbing resin box 9. One end of the second connecting pipe 17 is fixedly connected to the externally threaded connecting pipe 7, and the externally threaded connecting pipe 7 is coaxially threadedly connected to the threaded groove 11 on the first connecting pipe 10. One end of the tubular support 6 has a second round hole 18, which corresponds to the outer cylindrical surface of the second connecting pipe 17. The second round hole 18 is coaxially fixedly connected to the end of the second connecting pipe 17 facing away from the externally threaded connecting pipe 7. The water-absorbing resin box 9 is fixedly snapped into the inner part of the second connecting pipe 17. The externally threaded connecting pipe 7 is threadedly connected to the threaded groove 11, which facilitates the disassembly and replacement of the air intake component. The tubular support 6 is used to house the dual filter 8. The water-absorbing resin box 9 has a mesh structure and contains a highly absorbent material that is not highly volatile and non-toxic.

[0029] Furthermore, the inner wall of the tubular support 6 is coaxially fixed to the end away from the connecting pipe 17, with the arc-shaped cover 12 protruding away from the connecting pipe 17. A gas separation membrane 13 is connected through the center of the arc-shaped cover 12. A double filter 8 is provided between the tubular support 6 and the arc-shaped cover 12. A circular hole 16 is provided through the end of the tubular support 6 away from the circular hole 18. The arc-shaped cover 12 and the circular hole 16 are used to place the double filter 8. The arc-shaped cover 12 increases the contact area with water vapor and accelerates water vapor condensation. The gas separation membrane 13 is a selective membrane with a large permeation flux, which can filter air and block water.

[0030] Furthermore, the second waterproof structure includes a dustproof cloth 14, protrusions 15, and a cover plate 5. The dustproof cloth 14 is fixedly connected to the round hole 16 on the tubular support member 6. A group of evenly distributed protrusions 15 arranged in a circular pattern are fixedly connected to the outer surface of the round hole 16 on the tubular support member 6. The other side of the protrusions 15 is fixedly connected to the inner plane of the cover plate 5. One end of the cover plate 5 faces the tubular support member 6. The dustproof cloth 14 is used to block dust, and the protrusions 15 are used to increase the contact area with water vapor in the air and accelerate water vapor condensation.

[0031] Working principle: The mask 1 is placed on the user's face, the headband 3 is placed on the user's head, the transparent frame 2 corresponds to the user's eyes, and the exhalation component 4 corresponds to the user's nose and mouth. When the user is in a relatively humid environment, air enters the cover 5 through the gap between the opening end of the cover 5 and the tubular support 6. The air first passes through the protrusion 15 between the cover 5 and the tubular support 6. Some of the water vapor in the air will condense between the protrusions 15. The air continues to pass through the dustproof cloth 14 to block dust. At this time, a small amount of water vapor enters the tubular support 6 and passes through the gas separation membrane 13. The remaining water vapor adheres to the arc cover 12. The water vapor will not enter the double filter 8 inside the arc cover 12 and the tubular support 6. At the same time, the water vapor generated by the user's breathing is absorbed by the water-absorbing resin box 9 and will not come into contact with the water-absorbing resin box 9.
