Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lung capacity training technology, and in particular relates to a lung capacity training device. Background Technology
[0002] Vital capacity represents the maximum functional capacity of the lungs in a single breath and is one of the important functional indicators reflecting the level of human growth and development. Vital capacity training essentially increases lung volume by strengthening respiratory muscle strength and control, thereby improving inhalation and exhalation capacity. Vital capacity measurement is one of the routine tests in respiratory medicine physical examinations. Because a decrease in vital capacity can easily lead to various lung diseases, patients in respiratory medicine need to perform vital capacity exercises regularly. Through the process of vital capacity training, the oxygen utilization rate of the heart and lungs can be improved, blood circulation can be improved, cardiopulmonary function can be enhanced, and the risk of cardiovascular disease can be reduced.
[0003] Currently, most lung capacity training devices in existing technologies use the elastic deformation characteristics of springs for lung capacity training. The elastic reaction force generated by the spring deformation acts as resistance to blowing air, thereby achieving the purpose of lung capacity training. However, in actual use, it has been found that the resistance generated by the spring deformation gradually increases with the increase of the spring deformation, making it impossible to achieve a fixed intensity of training. It is also difficult to control. Furthermore, after repeated use, the spring will experience elastic fatigue, which can easily lead to a decrease in the accuracy of the set training intensity, thus affecting the training effect of lung capacity. Utility Model Content
[0004] The purpose of this invention is to provide a lung capacity training device with a simple structure and accurate control of training intensity.
[0005] The lung capacity training device includes a connecting tube, a vertical tube communicating with the right end of the connecting tube, a housing communicating with the connecting tube at the left end of the connecting tube, a blocking component for blocking saliva inside the housing, a secondary tube communicating with the housing at the left side of the housing, a connecting component for connecting a disposable air nozzle at the left end of the secondary tube, a hollow ball that moves up and down along the length of the vertical tube inside the vertical tube, and an adjustment component for adjusting the training intensity at the upper end of the vertical tube.
[0006] Furthermore, the adjustment component includes a top plate, which is horizontally fixed at the opening of the vertical pipe. The top plate has several ventilation holes that are connected vertically, and all ventilation holes are located on the same side of the radius of the top plate. A freely rotating cover plate is fitted at the opening of the vertical pipe, and a through groove that is connected vertically is provided on the top of the rotating cover plate. The through groove has a semi-circular structure.
[0007] Furthermore, the blocking assembly includes at least three rotating plates, with a freely rotating shaft horizontally inserted in the front and back of the housing. The rotating plates are all fixed on the rotating shaft. A base plate is detachably installed at the bottom of the housing, and absorbent cotton is horizontally fixed on the top of the base plate.
[0008] Furthermore, a magnetic block is embedded in the bottom of the housing, and the base plate is made of a metal material that can be attracted by the magnetic block.
[0009] Furthermore, the connecting assembly includes a threaded sleeve, which is fitted onto the left end of the secondary tube and threaded therewith. The left end of the secondary tube has a slot with an annular structure. An insert block with a wedge-shaped fit is independently installed in the slot and fixed to the threaded sleeve.

[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] In this invention, the connecting component facilitates the disassembly and assembly of disposable air nozzles. When the user blows air into the secondary tube, the air enters the housing. The blocking component traps saliva in the air within the housing, preventing saliva from contaminating the connecting tube. The air then enters the vertical tube through the connecting tube. The airflow moves upward, pushing the hollow ball upward. As the hollow ball moves, it expels air from above the hollow ball into the vertical tube. The adjusting component adjusts the ease with which the air exits the vertical tube, thereby accurately regulating the intensity of lung capacity training. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
[0019] Example 1
[0020] The lung capacity training device described in this embodiment, such as Figures 1 to 3 As shown, it includes a connecting pipe 3, and a vertical pipe 7 that communicates with the connecting pipe 3 is vertically inserted through the right end of the connecting pipe 3. The connecting pipe 3 has a through hole that communicates with the inside and outside. The lower end of the vertical pipe 7 is inserted into the through hole, and the gas in the connecting pipe 3 enters the vertical pipe 7.
[0021] The left end of the connecting pipe 3 is provided with a housing 1 that communicates with the connecting pipe 3. The housing 1 is a hollow rectangular structure. The right side wall of the housing 1 has a through hole that communicates with the inside and outside. The left end of the connecting pipe 3 is horizontally inserted into the through hole, and the gas in the housing 1 enters the connecting pipe 3.
[0022] A freely rotating shaft is horizontally inserted front and back inside the housing 1. At least three rotating plates 2 are fixed on the shaft. When gas enters the housing 1 through the secondary pipe 15, the gas flows to the right and impacts the rotating plates 2, thereby pushing the rotating plates 2 to rotate. When the gas collides with the rotating plates 2, the saliva in the gas remains on the rotating plates 2. When the rotating plates 2 rotate to the bottom of the shaft, the saliva flows downward to the absorbent cotton 13. A bottom plate 14 is detachably installed at the bottom of the housing 1. The absorbent cotton 13 is horizontally fixed on the top of the bottom plate 14. The absorbent cotton 13 is existing technology and is mainly made of polymer materials such as polyester, polyurethane, polyamide, and polypropylene. It has strong water absorption properties and can quickly absorb and lock in water. To reduce backflow, absorbent cotton, commonly used in feminine hygiene products, is used in this section. This section as a whole constitutes a saliva-blocking component. When the user blows air into the secondary tube 15 and into the housing 1, it pushes the rotating plate 2 to rotate. When the air contacts the rotating plate 2, the saliva in the air remains on the rotating plate 2. When the rotating plate 2 rotates below the shaft, the saliva flows downwards onto the absorbent cotton 13, where it is absorbed, preventing saliva from entering and contaminating the connecting tube 3. Of course, in the blocking component, the rotating plate 2 is made of plastic, and several protrusions are provided on its surface, making it uneven and improving the saliva retention effect.
[0023] A secondary pipe 15, which communicates with the housing 1, is horizontally inserted on the left side of the housing 1. A through hole is opened at the left end of the housing 1, and the right end of the secondary pipe 15 is horizontally inserted into the through hole. The gas in the secondary pipe 15 enters the housing 1.
[0024] A threaded sleeve 16 is fitted onto the left end of the secondary tube 15, and an external thread is provided on the outer wall of the left end of the secondary tube 15. The threaded sleeve 16 is fitted onto the left end of the secondary tube 15, forming a threaded engagement. A slot with a ring structure is provided on the left end of the secondary tube 15. An insert block 17 with a wedge-shaped engagement is independently installed in the slot. The insert block 17 is fixed to the threaded sleeve 16. When the threaded sleeve 16 rotates, it drives the insert block 17 to move within the slot, fixing the nozzle of the disposable air nozzle within the slot. This paragraph as a whole constitutes a connector for connecting disposable air nozzles. When using the connecting assembly, pass the nozzle of the disposable air nozzle through the threaded sleeve 16, insert the nozzle into the slot of the secondary tube 15, tighten the threaded sleeve 16 on the left end of the secondary tube 15, and when the threaded sleeve 16 moves to the right, it will drive the insert block 17 to move to the right as well. The right end of the insert block 17 will be inserted into the slot, and the nozzle of the disposable air nozzle will be pressed into the slot by the insert block 17, thus connecting the disposable air nozzle to the left end of the secondary tube 15. Of course, the insert block 17 in the connecting assembly can also be replaced with a ring structure. The ring structure insert block 17 fits into the ring structure slot, improving the fixing effect of the disposable air nozzle.
[0025] A hollow ball 6 is installed inside the vertical tube 7, which moves up and down along the length of the vertical tube 7. The diameter of the hollow ball 6 is the same as the inner diameter of the vertical tube 7. The hollow ball 6 moves up and down along the length of the vertical tube 7 under the push of air.
[0026] A top plate 10 is horizontally fixed at the opening of the vertical pipe 7, sealing the upper end of the vertical pipe 7. Several ventilation holes 11, interconnected vertically, are provided on the top plate 10, all located on the same side of the radius of the top plate 10. Figure 3 As shown, the ventilation holes 11 are located on the same side of the radius of the top plate 10, which facilitates subsequent adjustment of training intensity. A freely rotating cover plate 8 is fitted at the opening of the vertical pipe 7, covering the upper end of the vertical pipe 7. The rotation of the cover plate 8 controls the number of ventilation holes 11 that are connected to the outside. The top of the cover plate 8 has a through groove 9 that is semi-circular in shape, and the structure of the through groove 9 matches the structure of the ventilation holes 11. This section constitutes an adjustment component for adjusting training intensity. When using the adjustment component, the number of overlaps between the ventilation holes 11 and the through groove 9 is adjusted by rotating the cover plate 8. The more ventilation holes 11 and through groove 9 are connected, the easier it is for air to be discharged to the outside through the ventilation holes 11, and the lower the intensity of lung capacity training. Of course, in the adjustment component, the top of the top plate 10 is close to the inner bottom of the rotating cover plate 8 to prevent air from flowing out through the gap between the top plate 10 and the rotating cover plate 8, which would affect the adjustment accuracy of the training.
[0027] In this embodiment, a disposable air nozzle is connected to the left end of the secondary tube 15 via a connecting assembly. The patient blows air into the secondary tube 15 through the air nozzle. The air in the secondary tube 15 enters the housing 1. As the air passes through the housing 1, a blocking assembly prevents saliva in the air from contaminating the connecting tube 3. The air in the housing 1 then enters the vertical tube 7 through the connecting tube 3. The air enters from the lower end of the vertical tube 7. As the air rises, it pushes the hollow ball 6 upward along the length of the vertical tube 7. When the hollow ball 6 moves upward, the air in the upper half of the hollow ball 6 is discharged from the upper end of the vertical tube 7. The ease with which the air is discharged from the vertical tube 7 is adjusted by the adjusting assembly, thereby adjusting the intensity of the lung capacity training.
[0028] Example 2
[0029] This embodiment further illustrates the technology, such as Figure 1 As shown, a magnetic block 12 is embedded in the bottom of the housing 1, and the bottom plate 14 is made of a metal material that can be attracted by the magnetic block 12. A groove is opened on the bottom of the housing 1, and the magnetic block 12 is embedded in the groove. When the bottom plate 14 is close to the bottom of the housing 1, the magnetic block 12 attracts the bottom plate 14 to the bottom of the housing 1, sealing the bottom of the housing 1, realizing the quick disassembly of the bottom plate 14, which is convenient for replacing the absorbent cotton 13 and cleaning the housing 1, and reducing bacterial growth.
[0030] Example 3
[0031] This embodiment further illustrates the technology, such as Figure 1 As shown, an air outlet pipe 4 is vertically installed on the connecting pipe 3 between the housing 1 and the vertical pipe 7. A cover plate 5 is installed on the top of the air outlet pipe 4. A through hole is opened on the top of the connecting pipe 3, and the lower end of the air outlet pipe 4 is vertically inserted into the through hole and connected to the connecting pipe 3. After training, the cover plate 5 is removed from the air outlet pipe 4 to release the gas in the vertical pipe 7. The hollow ball 6 falls back to the bottom of the vertical pipe 7 for future use. The air outlet pipe 4 also facilitates the cleaning of the connecting pipe 3.
[0032] Example 4
[0033] This embodiment further illustrates the technology, such as Figure 1 As shown, the vertical tube 7 is made of transparent material, such as transparent plastic or glass. The transparent vertical tube 7 facilitates observation of the movement of the hollow ball 6 and understanding of the training process.
[0034] The outer wall of the vertical tube 7 is provided with scale lines, which quantify the movement distance of the hollow ball 6, making it easier for users to record the training results of lung capacity.
