[0002] A breathing trainer is a medical or fitness device that regulates or strengthens respiratory function through specific methods. Its core function is to improve breathing efficiency and enhance respiratory muscle strength through scientific training, and to assist in the treatment or prevention of respiratory problems. If the gas provided by the breathing trainer is too dry (especially during prolonged use or at high flow rates), it may cause dryness, irritation, or even damage to the mucous membranes of the throat or airways; or it may irritate sensitive airways due to the inhalation of cold air. Therefore, a gas processing device needs to be installed in the breathing trainer to treat the gas and avoid some adverse effects caused by the gas during breathing training.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figures 1 to 5 This utility model provides a modular gas processing device for a breathing trainer, including a mouthpiece 1, a switching valve 2, a first housing 3, and a second housing 4. The switching valve 2 includes a valve body 21 and a switching disc 22. The valve body 21 has an outlet chamber 211, a first inlet chamber 212, and a second inlet chamber 213. The mouthpiece 1 is connected to the outlet chamber 211. The first housing 3 is connected to the first inlet chamber 212. The second housing 4 is connected to the second inlet chamber 213. The switching disc 22 has an outlet hole 221 and an inlet hole 222. The outlet hole 221 is connected to the outlet chamber 211. The switching disc 22 is rotatably connected to the valve body 21. The inlet hole 222 selectively connects to the first inlet chamber 212, the second inlet chamber 213, or simultaneously connects to both the first inlet chamber 212 and the second inlet chamber 213.

[0020] Therefore, in practical applications, a heating module 5 can be added to the first housing 3, and a humidifying module 6 can be added to the second housing 4. By rotating the switching disk 22, the gas that finally enters the mouthpiece 1 can be heated gas, humidified gas, or a mixture of gases. It can be understood that when only heated gas is needed, rotating the switching disk 22 will connect the air inlet 222 only to the first air inlet chamber 212, and the second air inlet chamber 213 will be closed by the switching disk 22. When inhaling, the gas flows from the outside through the heating module 5 into the first air inlet chamber 212, flows out from the air inlet 222, and then flows into the air outlet chamber 211 from the air outlet 221. The gas in the air outlet chamber 211 enters the human body through the mouthpiece 1. When a mixed gas needs to be inhaled, the switching disc 22 is rotated so that the air inlet 222 can simultaneously connect with both the second air inlet chamber 213 and the first air inlet chamber 212. During inhalation, gas flows from the outside through the heating module 5 into the first air inlet chamber 212, and gas also flows from the outside through the humidification module 6 into the second air inlet chamber 213. Both types of gas simultaneously flow out from the air inlet 222 to form a mixed gas. The mixed gas then flows from the air outlet 221 into the air outlet chamber 211, and the gas in the air outlet chamber 211 enters the body through the mouthpiece 1. In addition, by rotating the switching disc 22, the area ratio of the air inlet 222 when connected to the second air inlet chamber 213 and the first air inlet chamber 212 can be switched, thereby adjusting the ratio of temperature and humidity in the mixed gas.

[0021] It is worth noting that the diameter of the air outlet 221 needs to be larger than the diameter of the air inlet 222 to ensure that the air outlet 221 is always connected to the air outlet 211, whether the air inlet 222 is connected to the first air inlet chamber 212, the second air inlet chamber 213, or both air inlets.

[0022] According to some embodiments of the present invention, the first housing 3 is detachably connected to the valve body 21 so that the first housing 3 communicates with the first air intake chamber 212, and the second housing 4 is detachably connected to the valve body 21 so that the two housings communicate with the second air intake chamber 213. In this embodiment, the first housing 3 and the second housing 4 are detachable, which facilitates the replacement of each housing.

[0023] For example, both the first housing 3 and the second housing 4 are threadedly connected to the valve body 21.

[0024] According to some embodiments of this utility model, the first housing 3 includes a first outer shell 31 and a first rotating cover 32. The first outer shell 31 is detachably connected to the valve body 21. The first rotating cover 32 has a first through hole 321, and the first outer shell 31 has a second through hole 311 at the end away from the valve body 21. The first rotating cover 32 is rotatably disposed on the end of the first outer shell 31 away from the valve body 21 to change the overlapping area of ​​the first through hole 321 and the second through hole 311. Since the first rotating cover 32 is rotatably connected to the first outer shell 31, rotating the first rotating cover 32 can increase the resistance to inhalation, forcing the respiratory muscles (such as the diaphragm and intercostal muscles) to contract more forcefully, thereby enhancing muscle strength and endurance, and thus achieving a training effect.

[0025] According to some embodiments of this utility model, a first sealing ring 33 is provided at the connection between the first outer shell 31 and the valve body 21. In this embodiment, the first sealing ring 33 ensures airtightness between the first outer shell 31 and the valve body 21, thereby ensuring the desired training effect is achieved.

[0026] The structures of the first shell 3 and the second shell 4 are similar, and will not be described in detail here.

[0027] According to some embodiments of this utility model, the switching valve 2 further includes a knob 23 and a rotating shaft 24. One end of the rotating shaft 24 is connected to the switching disc 22, and the other end passes through the upper part of the valve body 21 and is connected to the knob 23. Twisting the knob 23 and the rotating shaft 24 drives the switching disc 22 to rotate. The knob 23 has a simple design and is easy to operate. Of course, those skilled in the art can drive the valve disc to rotate electrically, and the specific configuration can be adjusted according to the actual application.

[0028] According to some embodiments of this utility model, the knob 23 is provided with anti-slip stripes 231. The aforementioned anti-slip stripes 231 can increase the friction when the hand makes adjustments.

[0029] According to some embodiments of this utility model, a second sealing ring 241 is provided between the rotating shaft 24 and the valve body 21. In this embodiment, the second sealing ring 241 can improve the airtightness between the rotating shaft 24 and the valve body 21 and prevent gas leakage.

[0030] According to some embodiments of this utility model, the mouthpiece 1 includes a wrapping portion 11 and a transverse portion 12. The transverse portion 12 protrudes from the inner peripheral wall of the wrapping portion 11. The wrapping portion 11 is used to abut against the mouth, and the transverse portion 12 is for teeth to bite. When the user uses the mouthpiece 1, the wrapping portion 11 is close to the mouth, and the upper and lower teeth bite into the transverse portion 12, effectively preventing the mouthpiece 1 from falling off during training. Furthermore, the transverse portion 12 has a protruding longitudinal portion 13, which, together with the wrapping portion 11, forms a space that can accommodate teeth. In this embodiment, the longitudinal portion 13 abuts against the inner side of the teeth during exhalation, thereby improving stability during breathing training.
