Description

Technical Field

[0001] The invention relates to the technical field of breathing training equipment, in particular to a breathing training device. Background Art

[0002] Nowadays, it is common to use respirators for respiratory function training during rehabilitation lung function treatment and breathing training for athletes.

[0003] CN201922276778.6 discloses a breathing trainer, one end of which is connected to a mouthpiece, and the other end of the main body is connected to a graduated tube and a breathing mouthpiece in sequence. A core column is arranged inside the main body and the graduated tube, and a spring is arranged between the core column and the main body. The end of the core column is against the graduated tube, and the strength and endurance of the inspiratory muscles (diaphragm and intercostal muscles) are increased through adjustable resistance training. The unique structural design allows the trainer to have both multi-level adjustable resistance and excellent portability that can be used normally without the assistance of both hands. The two air ducts of inhalation and exhalation are creatively optimized and combined into one, reducing the volume and weight, while increasing multi-level adjustable resistance. The other hand cooperates with some combined exercises to improve the exercise effect. After a period of training, the strength and endurance of the respiratory muscles can be significantly increased. This structural design is not stepless speed regulation, has many structural components, and is complex to assemble. At the same time, a spring is used, and the elastic force of the spring will fail or the effect will be weakened after a long period of cooperation. Summary of the invention

[0004] In order to solve the above technical deficiencies, the present invention provides a breathing trainer, which is easy to use, has a simple structure and can independently adjust the inhalation and exhalation resistances.

[0005] The present invention discloses a breathing trainer, comprising a mouthpiece, a shell, an exhalation valve and an inhalation valve, wherein the mouthpiece is connected to the shell and is internally provided with mutually connected airways, the airways extending from the inside of the shell to the inside of the mouthpiece and being connected with the outside world from one end of the mouthpiece; at least two concave cavities are arranged on the outer wall of the shell, air vents are arranged on the bottom wall of the concave cavities of the shell and the air vents are connected with the airways, a valve cover is arranged on each concave cavity, the valve cover is threadedly connected to the shell at the corresponding position of the concave cavity, the valve cover is connected to the shell by rotating the thread to change the size of the area of ​​the concave cavity connected with the outside world, a one-way valve sheet is arranged on the shell corresponding to the air vent, the one-way valve sheet is used to limit the airflow direction passing through the air vent, the airflow direction of at least one air vent on the concave cavity is from the concave cavity to the airway, and the airflow direction of at least one air vent on the concave cavity is from the airway to the concave cavity. When the air flow direction of the vent is from the concave cavity to the airway, the one-way valve sheet corresponding to the vent is arranged on the shell in the airway. When the air flow direction of the vent is from the airway to the concave cavity, the one-way valve sheet corresponding to the vent is arranged on the shell in the concave cavity. Of course, the connection between the one-way valve sheet and the shell is: the one-way valve sheet at one end of the vent is connected to the shell, and the other end is not connected.

[0006] The above technical solution is to set an inner concave cavity and a valve cover on the shell, and realize the adjustment of the air inlet or air outlet area, that is, the adjustment of the air inlet opening and the air outlet opening, by rotating the thread thereof. At the same time, the reasonable design of the one-way valve plate realizes the independent control of the air inlet adjustment and the air outlet adjustment, so the individual adjustment and random combination of the exhalation resistance and the inhalation resistance in the breathing training process can be effectively changed. Thereby, the intensity and applicability of the breathing training for rehabilitation patients or athletes can be improved. Moreover, the adjustment between the air inlet resistance and the air outlet resistance will not interfere with each other, and both are adjusted by rotating the stud and the screw sleeve, which is stepless adjustment, with a large adjustment range and high adjustment accuracy. The adjustment accuracy will not be affected by long-term use, and the stability during use is high.

[0007] A stud is arranged at the center of the inner concave cavity, and a threaded sleeve is arranged at the center of the valve cover. The threaded sleeve is rotatably connected with the stud.

[0008] The outer diameter of the valve cover is larger than the inner diameter of the inner concave cavity, and an annular air inlet passage is formed between the top surface of the side wall of the inner concave cavity and the inner wall of the valve cover. The smaller the pitch of the stud, the higher the adjustment accuracy.

[0009] An annular groove is arranged on the shell outside the inner concave cavity, and an annular protrusion is arranged on the periphery of the valve cover. The annular protrusion is located in the annular groove, and there are gaps between the two side walls of the annular protrusion and the two side walls of the annular groove.

[0010] The above structural design forms a narrow air intake passage between the annular groove and the annular protrusion, thereby being able to more accurately adjust the air intake resistance and providing higher stability during use.

[0011] A knob limit post is provided on the side wall of the valve cover, and a housing limit post is provided on the housing corresponding to the knob limit post, and the housing limit post is used to limit the angle at which the knob limit post rotates following the valve cover. The design of this structure can limit the rotation range of the valve cover on the housing, thereby determining the adjustment range, and the valve cover will not fall off or be lost due to misoperation during use.

[0012] The breathing trainer obtained by the present invention can realize independent adjustment of the inhalation resistance and the exhalation resistance by utilizing reasonable structural design, so as to improve the strength and endurance of the expiratory muscles and the inspiratory muscles (diaphragm and intercostal muscles).
