Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of respiratory training equipment, in particular to a lock air valve with double limiting structure, a modular air nozzle and a use method. BACKGROUND

[0002] In the activities of respiratory rehabilitation, sports training, etc., the air nozzle is the key interface connecting people and equipment. The existing air nozzle products generally have poor sealing performance and are prone to leakage under high pressure. The operating parts are easily damaged due to excessive pressing, resulting in shortened service life. During use, only the lip force is relied on for fixation, which is easy to fatigue and slip, and the experience is not good. Moreover, when multiple people share the use, there is a significant cross-infection health risk, and it is costly to equip each person with a complete set of equipment. Therefore, it is of great significance to provide a modular air nozzle with precise structure, strong durability, comfortable use and economic solution to the health problem of multiple people. SUMMARY

[0003] The purpose of the present application is to provide a lock air valve with double limiting structure, a modular air nozzle and a use method, which solves the above-mentioned problems existing in the existing air nozzle.

[0004] To achieve the above-mentioned purpose, the present application adopts the following technical solutions: On the one hand, the present application provides a lock air valve with double limiting structure, which comprises: a valve body shell, which is a hollow channel, and a valve core that is axially reciprocally movable and is sleeved inside the valve body shell; Wherein, the valve core comprises: a gas release rod part extending out of the top opening of the valve body shell, a fixed rod part arranged opposite to the gas release rod part, and a valve head connected between the gas release rod part and the fixed rod part and having an outer diameter larger than that of the two parts; a second sealing member arranged on the outer periphery of the valve head, and a bottom sealing cover that is detachably closed at the bottom of the valve body shell, the bottom sealing cover being provided with a central guide hole through which the fixed rod part passes.

[0005] The bottom sealing cover is used as a first limiting structure to block the valve head and limit the inward movement of the valve core.

[0006] On the other hand, the present application provides a modular air nozzle, which comprises: a blowpipe with a hollow channel, the inner wall of the blowpipe being integrally provided with at least one integral limiting rib extending radially inward, and the center of the integral limiting rib forming a through hole.

[0007] Preferably, the lock air valve is placed in the hollow channel of the blowpipe, and the gas release rod part passes through the through hole.

[0008] a pressing cap is installed at the end of the deflation rod, wherein the outer diameter of the pressing cap is larger than the diameter of the through hole of the integral limiting rib, so that the pressing cap and the integral limiting rib together constitute a second limiting structure for preventing the air lock valve body from being pulled out of the blow pipe.

[0009] Preferably, a first sealing member is further included, which is annularly arranged between the outer peripheral wall of the valve body shell of the air lock valve and the inner wall of the blow pipe.

[0010] Preferably, the pressing cap is made of elastic material. Further, the color of the pressing cap is different from the color of the blow pipe.

[0011] Preferably, a detachable oral interface is further included, which comprises a hollow sleeve portion and a pair of wings extending from the sleeve portion.

[0012] The blowing end of the blow pipe is inserted into and accommodated in the hollow cavity of the sleeve portion, forming a fit.

[0013] Preferably, the wings are adapted to be bitten by the teeth of the user, and the upper and lower surfaces of the wings are provided with anti-slip textures.

[0014] Further, at least one modular reinforcing ring is further included, which is detachably sleeved on the non-blowing end of the blow pipe, for changing the outer diameter size of the port to adapt to different caliber loads.

[0015] In another aspect, the present application also provides a method for using the modular air nozzle, which comprises the following steps: a. assigning each user in the scene with an identifiable, personally-owned oral interface; b. when a specific user needs to use, taking the air nozzle body without the oral interface as a common component, wherein the air nozzle body comprises the blow pipe and the built-in air lock valve; c. installing the personally-owned oral interface of the user to the blowing end of the blow pipe of the air nozzle body; d. after use, taking off the personally-owned oral interface from the air nozzle body for subsequent personal storage or cleaning by the user.

[0016] Compared with the prior art, the present application has the following beneficial effects: In this invention, the bottom sealing cap of the airlock valve serves as the first limiting structure, restricting excessive inward movement of the valve core. Furthermore, the pressing cap and integrated limiting rib serve as the second limiting structure, preventing the airlock valve from dislodging. This dual limiting structure enhances the assembly stability and reliability of the airlock valve, preventing sealing failure due to displacement. The invention also ensures the coaxiality of the valve core's movement by having its fixing rod pass through the central guide hole, preventing uneven sealing and abnormal wear caused by lateral wobbling, thus ensuring long-term stability of the airlock function. Additionally, the detachable oral cavity connector, using tooth-biting flaps, transfers the fixing force from the lips to the teeth, completely solving the problems of lip fatigue and accidental slippage.
