Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and relates to a mask, and more particularly to a mask with replaceable filter material. Background Technology

[0002] Ordinary face masks are a single unit, filtering through multiple layers of meltblown fabric and other materials. Their protective effect decreases over time, and they usually need to be discarded and replaced entirely. In contrast, masks with replaceable filters (such as some protective masks) use a "mask + filter" design. The mask body is reusable; only the internal filter needs to be replaced periodically. This design typically offers better sealing, a higher level of protection, and is more economical and environmentally friendly.

[0003] Conventional protective masks have multiple holes on the main body for storing the filter. Usually, the unused filter material is replaced before use. Due to the structure, it is difficult to replace it directly in the usage scenario, resulting in low protective efficiency when used for a long time. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a replaceable filter material mask that is easy to assemble and disassemble and offers multi-layer protection.

[0005] The objective of this utility model can be achieved through the following technical solution: A replaceable filter material mask, characterized in that it includes a mask body and a filter assembly. The mask body has several through holes, the filter assembly is placed on the through holes, the filter assembly has a through-hole canister, the bottom of the canister has a locking bolt, and the top of the canister has a detachable filter box. The bottom of the locking bolt has a spiral rubber plug, the top of the filter box has a protruding control part, the top of the control part has a silicone end cap, the canister has a horizontally arranged support bracket, the support bracket has an axial support rod at its center, a suction cup is located at the bottom of the support rod, the spiral rubber plug has an integrated sealing block at its center, the suction cup abuts against the sealing block, and filter material is located between the support bracket and the silicone end cap.

[0006] In the aforementioned replaceable filter material mask, the control part has a plurality of friction protrusions on its side wall, friction grooves are provided on the friction protrusions, and a connecting chain is provided between the friction protrusions and the silicone end cap.

[0007] In the aforementioned replaceable filter mask, both the inner and outer walls of the can are provided with connecting threads, and the locking bolts and filter box are fixed to the can via the connecting threads.

[0008] Compared with existing technologies, this replaceable filter mask achieves detachable and replaceable filter material through a split design. The support rod suction cup can control the opening and closing of the spiral rubber stopper, reducing the entry of unfiltered external gas and making replacement more convenient and safer. Multiple filter structures allow the mask to be used alternately and replaced, making it adaptable to different usage scenarios, including multiple openings for movement, single openings for waiting for rescue, etc. The replacement method reduces the items the user needs to carry.

Detailed Implementation

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 , 2As shown in Figures 3 and 4, this filter material 6 is a replaceable mask, characterized by comprising a mask body 17 and a filter assembly 16. The mask body 17 has several through holes 18, the filter assembly 16 is placed on the through holes 18, and the filter assembly 16 has a through canister 3. The bottom of the canister 3 has a locking bolt 9, and the top of the canister 3 has a detachable filter box 1. The bottom of the locking bolt 9 has a spiral rubber plug 12. The top of the filter box 1 has a protruding control part 4, and the top of the control part 4 has a silicone end cap 5. The canister 3 has a horizontally arranged support bracket 13, and the support bracket 13 has an axial support rod 8 at its center. Before use, the canister 3 is connected to the locking bolt 9 and fixed to the through holes 18, and then installed... The filter box 1 is installed and the silicone end cap 5 is snapped onto the top of the filter box 1. When in use, simply open the silicone end cap 5 to begin use. When wearing the filter, replace the filter box 1 after the filter material 6 has reached its expiration date. When removing the filter box 1, the bottom suction cup 10 moves the spiral rubber upwards. With the elasticity of the spiral rubber, the spiral rubber plug 12 forms a circular rubber plug, preventing harmful gases from directly entering the mask body 17. The remaining filter boxes 1 provide continuous filtration and air supply. When reinstalling the filter box 1, the filter box 1 is first connected to the canister 3 to achieve a seal. As it is reinstalled, the suction cup 10 pushes out the sealing block 11, deforming the spiral rubber plug 12 to provide a passage. Then, open the silicone end cap 5 to allow air circulation and reduce the entry of harmful gases when replacing the filter material 6.

[0016] Preferably, the control unit 4 has a plurality of friction protrusions 15 on its side wall, and friction grooves 14 are provided on the friction protrusions 15. A connecting chain 2 is provided between the friction protrusions 15 and the silicone end cap 5. The friction protrusions 15 and the friction grooves 14 facilitate the user's control of the disassembly of the filter canister. The connecting chain 2 ensures that the silicone end cap 5 is always integrated with the filter box 1 when it is disassembled, which facilitates subsequent recycling and reuse. After the suction cup 10 comes into contact with the sealing block 11, the suction cup 10 rotates with the filter box 1, which causes the spiral rubber stopper 12 to deform.

[0017] Preferably, the tank body 3 has connecting threads 7 on both the inner and outer walls. The locking bolts 9 and the filter box 1 are fixed to the tank body 3 through the connecting threads 7. The threads have self-closing properties. At the same time, the filter box 1 is installed through the threads, which enables the suction cup 10 to move relatively stably in the axial direction, reducing the left and right shaking that causes the spiral rubber plug 12 to not close properly.

[0018] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0019] Although this document frequently uses terms such as filter box 1, connecting chain 2, tank body 3, control unit 4, silicone end cap 5, filter media 6, connecting thread 7, support rod 8, locking bolt 9, suction cup 10, sealing block 11, spiral rubber plug 12, support bracket 13, friction groove 14, friction protrusion 15, filter assembly 16, mask body 17, and through hole 18, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
