Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Referring to Figure 1 , Figure 4 and Figure 6 , an auxiliary breathing exercise device for lung cancer patients provided by an embodiment of the present invention includes a face mask 1. A filter cartridge 5 is arranged at the bottom of the face mask 1. An operating mechanism 2 is arranged inside the filter cartridge 5. The operating mechanism 2 is used to control the breathing intensity. A disassembly and assembly mechanism 3 is arranged at the top of the filter cartridge 5. The disassembly and assembly mechanism 3 is used to replace and maintain the device. A positioning mechanism 4 is arranged at the rear side of the face mask 1. The positioning mechanism 4 is used for the user to wear the device;

[0032] The operating mechanism 2 includes a hollow block 21 which is connected to the left top of the face mask 1. A gear 22 is rotatably connected to the inner side of the hollow block 21. A piston 24 is fixedly connected to the top inner side of the face mask 1. A first threaded cover 211 is rotatably connected to the bottom of the piston 24. A toothed ring 23 is fixedly connected to the outer side of the first threaded cover 211. Rotating the toothed ring 23 will drive the first threaded cover 211 to rotate. The toothed ring 23 is meshed with the gear 22. Rotating the toothed ring 23 can drive the gear 22 to rotate. The middle part of the top end of the piston 24 is communicated with a one-way valve 25 which can allow air flow during inhalation and prevent air from passing through the piston 24 during exhalation. A threaded ring 26 is threadedly connected to the inner side of the first threaded cover 211. A lifting disc 210 is fixedly connected to the bottom of the threaded ring 26. Rotating the first threaded cover 211 can push the threaded ring 26 and the lifting disc 210 to move. The lifting disc 210 is slidably connected to the filter cartridge 5. A plurality of spring rods 27 are fixedly connected to the bottom inner side of the filter cartridge 5. The spring rods 27 are fixedly connected to the lifting disc 210. The elastic potential energy provided by the spring rods 27 can provide resistance for breathing for exercise. A guiding component 28 is arranged at the bottom of the piston 24. An indicating component 29 is arranged on the left side of the filter cartridge 5;

[0033] Specifically, when the user wears the face mask 1 and starts breathing, the one-way valve 25 opens during inhalation to inhale oxygen to prevent asphyxiation. The one-way valve 25 closes during exhalation. The piston 24 moves with breathing, and the spring rods 27 expand and contract accordingly. Their elastic force forms a breathing resistance to prompt the user to breathe forcefully to achieve the exercise effect. At the same time, the user rotates the gear 22 to drive the toothed ring 23 and the first threaded cover 211 to rotate, thereby moving the threaded ring 26 and the lifting disc 210 up and down, so as to adjust the tightening degree of the spring rods 27 and realize the intuitive and accurate adjustment of the breathing resistance.

[0034] Referring to Figure 4 、 Figure 5 and Figure 7 ,the disassembly and assembly mechanism 3 includes an installation ring 31 which is fixedly connected to the top of the filter cartridge 5. The filter cartridge 5 is fixedly connected to the face mask 1 through the installation ring 31. A spring telescopic tube 32 is slidably connected to the inner side of the installation ring 31. U-shaped clamping plates 33 are fixedly connected to the front and rear sides of the outside of the spring telescopic tube 32. The telescopic movement of the spring telescopic tube 32 can drive the U-shaped clamping plates 33 to move simultaneously. Limiting plates 34 are fixedly connected to the left and right sides of the top of the filter cartridge 5. The limiting plates 34 are engaged with the U-shaped clamping plates 33. A first filter disc 35 is fixedly connected to the top of the installation ring 31. A second filter disc 36 is rotatably connected to the outside of the first filter disc 35. Separating the engagement between the limiting plate 34 and the U-shaped clamping plate 33 can simultaneously separate the connection between the face mask 1 and the filter cartridge 5. A sealing component 37 is arranged at the bottom of the filter cartridge 5;

[0035] Specifically, press the spring telescopic tubes 32 on the front and rear sides of the mounting ring 31 to simultaneously expand and contract the U-shaped clamping plates 33 connected to both sides thereof until the two ends of the U-shaped clamping plates 33 are joined together to release the clamping of the limiting plate 34. In this way, the filter cartridge 5 at the bottom of the mounting ring 31 can be removed from the face mask 1 for replacement. Before installing the mounting ring 31, rotate the second filter disc 36 to rotate it along the first filter disc 35. By adjusting the size of the gap formed by the intersection and stagger of the holes in the two filter discs, the air flow permeability can be controlled, and the breathing force required by the user can be further adjusted.

[0036] Referring to Figure 2 , Figure 3 and Figure 8 , the positioning mechanism 4 includes a hollow cover 41. The hollow cover 41 is arranged at the rear side of the face mask 1. A threaded column 42 is fixedly connected to the middle part of the inner side of the hollow cover 41. A rotating disc 43 is threadedly connected to the outer side of the threaded column 42. The rotating disc 43 can rotate along the threaded column 42. Positioning blocks 44 are fixedly connected to the outer periphery of the rotating disc 43. A restraint strap 45 is fixedly connected to the outer side of the positioning block 44. When the rotating disc 43 and the positioning blocks 44 thereon rotate, the restraint strap 45 can be wound into the hollow cover 41. The other end of the restraint strap 45 is fixedly connected to the face mask 1. The restraint strap 45 and the hollow cover 41 facilitate the wearing of the face mask 1. A fixing component 46 is arranged on the outer side of the rotating disc 43, and an auxiliary component 47 is arranged on the front side of the hollow cover 41;

[0037] Specifically, the user pushes the rotating disc 43 along the threaded column 42 and rotates it. After the rotating disc 43 stops rotating, precise positioning can be achieved by means of the cooperation with the threaded column 42. As the rotating disc 43 rotates, the positioning blocks 44 arranged thereon will also rotate synchronously. During the rotation process, the positioning blocks 44 will wind the restraint strap 45 into the hollow cover 41, thereby completing the tightening action of the restraint strap 45. When the user wears the face mask 1 on the head with the help of the restraint strap 45 and the hollow cover 41, the wearing tightness of the face mask 1 can be flexibly adjusted by tightening or loosening the restraint strap 45 according to the characteristics of their own head shape.

[0038] Referring to Figure 2 , Figure 4 and Figure 5, the guiding component 28 includes guide rods 281. A plurality of guide rods 281 are respectively fixedly connected to the periphery of the bottom of the piston 24. The outer sides of the guide rods 281 are slidably connected to the lifting disc 210. A limiting block 282 is fixedly connected to the bottom of the guide rods 281. The guide rods 281 can improve the stability of the lifting disc 210 during movement and limit its moving distance at the same time; the indicating component 29 includes an indicating disc 291. The indicating disc 291 is rotatably connected to the top of the hollow block 21. The bottom of the hollow block 21 penetrates through the hollow block 21 and is fixedly connected to the gear 22. A pointer 292 is fixedly connected to the top left of the filter cartridge 5. When the indicating disc 291 rotates with the gear 22, by observing the position indicated by the pointer 292, the rotation angle of the current gear 22 can be judged;

[0039] Specifically, through the sliding of the guide rods 281 with the lifting disc 210, the stability of the lifting disc 210 during up and down movement can be improved, and at the same time, the moving distance of the lifting disc 210 is limited by the limiting block 282. When the gear 22 rotates, it will drive the indicating disc 291 to rotate accordingly. At this time, by observing the position indicated by the pointer 292, the rotation angle of the current gear 22 and the position of the lifting disc 210 can be judged.

[0040] Refer to Figure 1 、 Figure 3 and Figure 5 , the sealing component 37 includes an air inlet cover 371. The air inlet cover 371 is communicated with the bottom of the filter cartridge 5. A second threaded cover 372 is threadedly connected to the outside of the air inlet cover 371. The air inlet cover 371 can facilitate the flow of air, and at the same time, by rotating and disassembling the second threaded cover 372, it can prevent external dust from entering the device when the device is not in use; a positioning frame 6 is fixedly connected to the inner side of the right end of the filter cartridge 5. An observation window 7 is fixedly connected to the inside of the positioning frame 6. Through the observation window 7 in the positioning frame 6, it is convenient to directly observe the moving position of the piston 24; a handle 8 is rotatably connected to the bottom of the hollow block 21. The top of the handle 8 penetrates through the hollow block 21 and is fixedly connected to the gear 22. When the handle 8 rotates, it can drive the gear 22 on it to rotate at the same time;

[0041] Specifically, the air inlet cover 371 can facilitate the flow of air for the user to breathe. When not in use, the air inlet cover 371 can be sealed by rotating the second threaded cover 372 to prevent dust from entering. Through the observation window 7 on the inner side of the positioning frame 6, it is convenient to directly observe the operation condition inside the device and the moving position of the piston 24. By operating the handle 8 to rotate, the gear 22 can be driven to rotate synchronously.

[0042] Refer to Figure 1 、 Figure 3 and Figure 8, the fixing component 46 includes an elastic band 461. A plurality of elastic bands 461 are respectively fixedly connected to the left and right outer sides of the binding band 45. Through the elastic band 461, the user's ears can be fixed by its own movement and contraction. A knob 462 is fixedly connected to the rear side of the rotating disc 43. By operating the knob 462, it is convenient to drive the rotating disc 43 to rotate; the auxiliary component 47 includes a cushion 471. The cushion 471 is fixedly connected to the front side of the hollow cover 41. Massage blocks 472 are fixedly connected to the outer periphery of the cushion 471;

[0043] Specifically, by moving the elastic band 461 on the outer side of the binding band 45 and through the contraction of the elastic band 461 itself, it is convenient to fix the user's ears. At the same time, by the knob 462, it is convenient to operate the rotating disc 43 to rotate. Through the cushion 471, the hollow cover 41 can fit the user's head more closely. At the same time, through the massage blocks 472 thereon, the discomfort of the user during wearing can be reduced.

[0044] Working principle: When the user wears the mask 1 and starts breathing, when inhaling, the one-way valve 25 opens to inhale oxygen to prevent asphyxiation. When exhaling, the one-way valve 25 closes and the piston 24 is pushed along with the breathing. At this time, the spring rod 27 can stretch and contract along with the movement of the piston 24. At the same time, the elastic potential energy of the spring rod 27 can provide resistance for breathing to force the user to exert force to achieve the exercise effect. Then, by rotating the gear 22, the toothed ring 23 and the threaded cover one 211 meshed with it can be driven to rotate, thereby driving the threaded ring 26 and the lifting disc 210 to move up and down to adjust the tightening degree of the spring rod 27, so as to intuitively and accurately adjust the resistance during breathing;

[0045] And by pressing the spring telescopic tubes 32 located on the front and rear sides of the mounting ring 31, so that both sides of it and the U-shaped clamping plates 33 thereon expand and contract simultaneously, the two ends of the U-shaped clamping plate 33 can be joined together to release the clamping of the limiting plate 34. At this time, the filter cartridge 5 at the bottom of the mounting ring 31 can be taken out from the mask 1, so as to facilitate the replacement of the filter cartridge 5. At the same time, before the mounting ring 31 is installed, by rotating the filter disc two 36 along the filter disc one 35, the size of the gap generated by the intersection and interlacing of the holes on the filter disc one 35 and the filter disc two 36 can be adjusted to control the air flow throughness, so as to further adjust the force required by the user during breathing;

[0046] Finally, by pushing the rotating disc 43 to rotate along the threaded column 42, it can be positioned after the rotating disc 43 stops through the threaded column 42. At this time, as the rotating disc 43 rotates, the positioning block 44 thereon will also rotate accordingly, and the binding band 45 will be wound into the hollow cover 41 for tightening during rotation. When the user wears the mask 1 to the head through the binding band 45 and the hollow cover 41, the binding band 45 can be tightened or loosened to adjust according to the user's head shape.
