[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 A filtering intelligent breathing mask in this embodiment includes a mask body 1, and a disassembly and assembly filtering mechanism is arranged on the front of the mask body 1.

[0023] The disassembly and assembly filtering mechanism comprises a filter tank 2 which is threadedly connected to the front face of the mask body 1, a fine filter plate 3 is fixedly installed inside the filter tank 2, two installation boxes 4 are fixedly installed on one side of the mask body 1, a return spring 5 is fixedly installed inside the installation box 4, a moving plate 6 is fixedly installed on one side of the return spring 5, and limit blocks 7 which are slidably connected to the inner wall of the installation box 4 are fixedly installed on both sides of the moving plate 6, and limit grooves are provided on both sides of the inner walls of the installation box 4, and the limit blocks 7 are slidably connected to the installation box 4 through the limit grooves, which helps to limit the limit blocks 7;

[0024] A limit pin 8 plugged into the filter tank 2 is fixedly installed on one side of the movable plate 6. A slot is provided on the outer side of the filter tank 2. The limit pin 8 is plugged into the filter tank 2 through the slot, which helps the limit pin 8 to limit and fix the filter tank 2 and remove and loosen it. A pull rod 9 extending to the outside of the installation box 4 is fixedly installed on the side of the movable plate 6 away from the limit pin 8. A flow pipe 10 is fixedly installed on one side of the filter tank 2. A filter assembly is provided on one side of the flow pipe 10. The filter assembly includes a branch pipe 11 fixedly installed on the left and right sides of the flow pipe 10, and the other end of the branch pipe 11 is movably connected with a filter tip 12 The internal threads of the filter tip 12 and the branch pipe 11 are provided with fixing bolts 13, and threaded grooves are provided inside the branch pipe 11 and the filter tip 12. The fixing bolts 13 are threadedly connected with the branch pipe 11 and the filter tip 12 through the threaded grooves, which facilitates the use of the fixing bolts 13 for disassembly and installation. A coarse filter plate 14 is fixedly installed inside the filter tip 12, and the filter hole size of the fine filter plate 3 is smaller than the filter hole size of the coarse filter plate 14, which facilitates multi-stage filtration. An observation window 15 is fixedly installed on the front of the mask body 1, and the observation window 15 is transparent glass, which facilitates visual observation.

[0025] It should be noted that the filtering intelligent breathing mask, through the disassembly and assembly filtering mechanism, uses the pull rod 9, the movable plate 6 and the reset spring 5 to drive the limit pin 8 to disengage and no longer plug and fix the filter tank 2, or can automatically reset the reset spring 5 and drive the movable plate 6 and the limit pin 8 to reset and move, so that the limit pin 8 is inserted into the interior of the filter tank 2 again for fixed installation, and the filter mouth 12 can also be disassembled and installed from the branch pipe 11 by using the fixing bolt 13, which greatly improves the flexibility of the device and the disassembly and assembly functions, facilitates the rapid assembly and disassembly and cleaning of the device in different situations, and improves practicality and flexibility.

[0026] The working principle of the above embodiment is:

[0027] When using the filtering intelligent breathing mask, the pull rod 9 is first pulled, and the pull rod 9 drives the movable plate 6 to move. The movable plate 6 moves smoothly under the limit of the limit block 7. The movable plate 6 moves inside the installation box 4 to drive the limit pin 8 to move. At the same time, the movement of the movable plate 6 compresses the reset spring 5 until the limit pin 8 is driven out of the slot on the outside of the filter tank 2, so that the limit pin 8 no longer plugs and fixes the filter tank 2. Then the filter tank 2 can be rotated until the filter tank 2 is removed from the front of the mask body 1, which is convenient for installation. The fine filter plate 3 inside the filter tank 2 is cleaned. Similarly, after the filter tank 2 is turned into the inner side of the mask body 1, the pull rod 9 is loosened, the reset spring 5 is automatically reset, and drives the movable plate 6 and the limit pin 8 to reset and move, so that the limit pin 8 is inserted into the interior of the filter tank 2 again for fixed installation. At the same time, the coarse filter plate 14 inside the filter tip 12 can be cleaned. The filter tip 12 can also be disassembled and installed from the branch pipe 11 using the fixing bolt 13, which greatly improves the flexibility of the device and the disassembly and assembly functions.
