DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the utility model more clearly understood, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and do not limit the utility model.

[0024] As Figures 1 to 5 shown, the breathing training device of the embodiment comprises a main air pipe 1, a breathing nozzle 2, a pressure regulating mechanism and a filter 6. The main air pipe 1 comprises a first end and a second end, and the breathing nozzle 2 is installed on the first end of the main air pipe 1. The pressure regulating mechanism is installed on the second end of the main air pipe 1. When breathing, the gas exhaled from the breathing nozzle 2 is discharged from one end of the pressure regulating mechanism. In addition, in order to facilitate inhalation, a sub air pipe 4 is connected to the side of the middle part of the main air pipe 1, the sub air pipe 4 is communicated with the main air pipe 1, and a one-way valve 12 is installed in the sub air pipe 4. The sub air pipe 4 serves as a handle so as to be held by the trainer. When inhaling, the external air enters the main air pipe 1 through the one-way valve 12 and then enters the breathing nozzle 2. A certain resistance is formed through the pressure regulating mechanism, so as to achieve the purpose of breathing training of the respiratory system of the patient.

[0025] Specifically, the pressure regulating mechanism comprises a sealing plate 7, a spring 11, a connecting rod 10 and a cap 3. The cap 3 is threadedly connected to the second end of the main air pipe 1. The main air pipe 1 is provided with a closed section 8 and an opening section 9. The diameter of the sealing plate 7 is equal to the inner diameter of the closed section 8, and the diameter of the sealing plate 7 is smaller than the inner diameter of the opening section 9. The sealing plate 7 is slidable on the closed section 8 and the opening section 9. One end of the connecting rod 10 is fixedly connected with the cap 3. The spring 11 is sleeved on the connecting rod 10. The two ends of the spring 11 are connected with the sealing plate 7 and the cap 3 respectively. The cap 3 is provided with a penetrating exhaust hole 5. By adjusting the position of the cap 3, the elasticity of the spring 11 can be adjusted, so as to change the size of the resistance.

[0026] In the process of patient breathing, saliva inevitably enters the main air pipe 1, polluting the inside of the main air pipe 1. For this reason, the filter 6 is installed on the end of the breathing nozzle 2 connected to the main air pipe 1. The filter 6 comprises a fixed seat, and a first filter cotton 64 and a second filter cotton 65 are arranged in the fixed seat. A first air passage 641 is arranged on the first filter cotton 64, and a second air passage 651 is arranged on the second filter cotton 65. The first air passage 641 and the second air passage 651 are staggered. The first air passage 641 and the second air passage 651 are both multiple waist-shaped holes and are arranged on the first filter cotton 64 and the second filter cotton 65 in a divergent manner. Specifically, the fixed seat comprises a first seat body 61 and a second seat body 62. The first seat body 61 and the second seat body 62 are both through at both ends. The first filter cotton 64 is installed in the first seat body 61, and the second filter cotton 65 is installed in the second seat body 62. One end of the second seat body 62 is connected to one end of the first seat body 61.

[0027] The first seat body 61 and the second seat body 62 are both provided with a spoke 66 for supporting the first filter cotton 64 and the second filter cotton 65. The end of the second seat body 62 is pressed against the outer edge of the first filter cotton 64. One end of the second seat body 62 is connected to a fastening ring 63, and the fastening ring 63 is pressed against the outer edge of the second filter cotton 65.

[0028] When the first filter cotton 64 and the second filter cotton 65 are installed, in order to avoid the first air passage 641 and the second air passage 651 from overlapping, the installation angle of the first filter cotton 64 and the second filter cotton 65 needs to be positioned. Therefore, a positioning column 67 is arranged in the middle of the spoke 66. The cross section of the positioning column 67 is polygonal. A polygonal positioning hole 68 is arranged in the middle of the first filter cotton 64 and the second filter cotton 65 and matches the positioning column 67. For example, the cross sections of the positioning column 67 and the positioning hole 68 are both rectangular in the embodiment. The first air passage 641 is T-shaped. The first air passage 641 and the first air passage 641 lower end cooperate. After they are connected, the first air passage 641 and the second air passage 651 have a certain direction, which ensures that they are staggered. Therefore, the first filter cotton 64 and the second filter cotton 65 can be fixed, and the anti-fool function is also achieved.

[0029] In order to avoid gas leakage between the breathing nozzle 2 and the filter 6, the first seat body 61 is sleeved on the end of the breathing nozzle 2. A sealing ring 13 is arranged between the first seat body 61 and the breathing nozzle 2.

[0030] When the trainer uses the breathing training device to train, the trainer exhales air to the breathing nozzle 2, saliva carried in the exhaled air is blocked by the filter 6, specifically, most of the saliva is blocked by the first filter cotton 64, a small part of the saliva passes through the first air passage hole 641, and is blocked when reaching the second filter cotton 65, and the airflow passes through the first air passage hole 641 and the second air passage hole 651, thereby reaching the sealing plate 7, pushing the sealing plate 7 to move to the opening section 9, and finally being discharged from the exhaust hole 5 of the cap 3, when inhaling, the sealing plate 7 is reset to the closed section 8 under the action of the spring 11, the air enters from the one-way valve 12 of the auxiliary air pipe 4, and finally flows to the breathing nozzle 2. In the embodiment, the first filter cotton 64 and the second filter cotton 65 are used for filtering, the blocking effect of the saliva is better, and the first air passage hole 641 and the second air passage hole 651 arranged to be staggered are beneficial to the passing of the airflow.

[0031] Although the embodiments of the utility model have been shown and described above, it can be understood that the above-mentioned embodiments are exemplary and cannot be understood as the limitation of the utility model, and the ordinary skilled in the art can change, modify, replace and transform the above-mentioned embodiments within the scope of the utility model.
