DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0031] like Figures 1 to 5 As shown, a vital capacity training device includes a shell 1, a constant pressure plate 2, and a control panel 4. The shell 1 is cylindrical, and the constant pressure plate 2 is slidably arranged in the shell 1. The inner cavity of the shell 1 is divided into a breathing cavity 101 at the lower end and a control cavity 102 at the upper end by the constant pressure plate. The breathing cavity 101 is provided with a closed space for exhalation training. The closed space can be achieved by directly sliding and sealing the constant pressure plate 2 and the shell 1, or a sealing ring can be provided on the outer edge of the constant pressure plate 2, and the sealing can be achieved by the cooperation between the sealing ring and the shell 1. The closed space can also be achieved by providing a telescopic airbag 103 between the lower end surface of the constant pressure plate 2 and the lower bottom surface of the shell 1.

[0032] The closed space is connected with a hose 3 , one end of the hose 3 is connected to the housing 1 through a threaded sleeve 301 , and the other end of the hose 3 is provided with a replaceable breathing nozzle 302 , through which exhalation is performed.

[0033] A control plate 4 is slidably arranged in the control chamber 102, a compression spring 201 is arranged between the control plate 4 and the constant pressure plate 2, a tension spring 203 is arranged between the constant pressure plate 2 and the upper end of the shell 1, the tension spring 203 and the compression spring 201 have the same elastic coefficient, the deformation of the compression spring 201 is greater than the deformation of the tension spring 203, when the initial deformation of the compression spring 201 and the tension spring 203 is determined, the difference in force applied by the compression spring 201 and the tension spring 203 to the constant pressure plate 2 is constant, which can ensure that the pressure in the closed space is constant during training.

[0034] In order to adjust the difference between the force applied by the compression spring 201 and the tension spring 203 to the constant pressure plate 2 to suit different training intensities, a position adjustment mechanism 5 is provided between the control plate 4 and the upper end of the housing 1. The position of the control plate 4 in the control chamber 102 is changed by the adjustment mechanism 5, thereby changing the distance between the control plate 4 and the constant pressure plate 2. The position adjustment mechanism 5 includes a screw rod 501 threadedly connected to the housing 1, the lower end of the screw rod 501 extends into the control chamber 102 and is rotatably connected to the control plate 4. By rotating the screw rod 501, the control plate 4 is driven to move up and down. A fastening nut 502 is provided on the screw rod 501. When adjusted to a suitable position, the fastening nut 502 is tightened to achieve locking.

[0035] In order to ensure that the constant pressure plate 2 does not deflect during movement, a guide device 202 is provided between the control plate 4 and the constant pressure plate 2. The guide device 202 includes a telescopic rod, one end of which is fixedly connected to the constant pressure plate 2, and the other end of the telescopic rod is fixedly connected to the control plate 4, so that the constant pressure plate 2 can only move along the axis of the telescopic rod.

[0036] In order to control the total air volume of a single exhalation, a vent hole is provided on the constant pressure plate 2, in which a vent pin 204 is slidably inserted, and there is a large friction between the vent pin 204 and the vent hole. A vertical hole 205 with an upper end opening is provided in the vent pin 204, and a transverse hole 206 connected with the vertical hole 205 is provided at the lower end of the side wall of the vent pin 204. The vent pin 204 is sealed and connected to the constant pressure plate 2. When the vent pin 204 is in the upper working position, the transverse hole 206 is in the vent hole and sealed with the side wall of the vent hole; when the vent pin 204 is in the lower working position, the closed space is connected with the control chamber 102 through the transverse hole 206 and the vertical hole 205. Since the control chamber 102 is connected with the outside, the constant pressure plate 2 returns downward under the action of the spring.

[0037] The control chamber 102 is provided with a deflation control rod 207 that cooperates with the deflation pin 204. The height of the deflation control rod 207 can be adjusted. The deflation control rod 207 can be a threaded rod threadedly connected to the shell; the lower end of the breathing chamber 101 is provided with a return control rod 208 that cooperates with the deflation pin 204.

[0038] The shell 1 is preferably made of a transparent material to facilitate penetration into the interior.

[0039] Working principle:

[0040] In the initial state, the constant pressure plate 2 is at the lower end of the breathing chamber 101 under the combined force of the compression spring 201 and the tension spring 203. At this time, the lower end of the deflation pin 204 contacts the return control rod 208, and the deflation pin 204 is in the upper working position; the user exhales through the breathing nozzle 302, and the gas enters the breathing chamber through the hose 3 and pushes the constant pressure plate 2 to move upward. When the set exhalation volume is reached, the deflation pin 204 contacts the deflation control rod 207 and moves downward relative to the constant pressure plate 2, so that the transverse hole 206 is connected to the breathing chamber 101, completing a breathing training.

[0041] The constant pressure plate 2 moves downward under the action of the spring until the deflation pin 204 contacts the return control rod 208, and the transverse hole 206 of the deflation pin 204 is closed, and the next breathing training can be carried out.

[0042] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention, and various changes should be included in the protection scope of the present invention.
