A partition plate 106 is fixedly installed on the top of the L-shaped support plate 101 to facilitate the cooperation with the pushing mechanism 200 to ensure the normal operation of the device. It also includes a pushing mechanism 200, an air flow regulating mechanism 300 and a collecting mechanism 400. The pushing mechanism 200 is arranged above the L-shaped support plate 101, and is used to adjust the exhalation pressure during vital capacity training, and can adjust the total amount of exhalation. The air flow regulating mechanism 300 is arranged on the outside of the airway 103, and is used to train the exhalation volume per unit time. The collecting mechanism 400 is arranged at the lower end of the L-shaped support plate 101, and is used to collect saliva carried in the exhaled volume during training, so as to facilitate subsequent cleaning operations.

[0029] Among them Figure 2-Figure 4 As shown, the pushing mechanism 200 includes a sphere 201 movably arranged inside the vertical cylinder 102. The sphere 201 is made of a light material, which is easy to blow up, interesting, and increases the viewing effect. A push plate 202 is arranged above the sphere 201. The user blows air into the vertical cylinder 102 through the breathing mask 104 and the air guide tube 103. The exhaled gas drives the sphere 201 to move upward, thereby pushing the push plate 202 to move upward, thereby driving the push rod 203 and the slide plate 204 to move. The scale data of the slide plate 204 at the limit column 206 can be used to know the training result of this time.

When the first vertical cylinder 102 is filled with exhaled gas, the exhalation training operation of the second, third, etc. vertical cylinders 102 is opened by the switch assembly, so as to achieve a progressive training effect.

[0030] Among them Figure 2-Figure 4As shown, the switch assembly includes a contact 208 fixedly mounted on the upper surface of the slide plate 204, a control switch 209 is arranged on the lower surface of the top plate 207, the contact 208 and the control switch 209 are arranged opposite to each other, the number of the contacts 208 is consistent with the number of the control valves 210, a plurality of control valves 210 are fixedly mounted on the shunt pipe 105, and the control valves 210 are electrically connected to the corresponding control switches 209. When the contact 208 contacts the control switch 209, a signal is transmitted to the corresponding control valve 210, i.e., the first control valve 210 on the right side of the contact 208, through the control switch 209. At this time, the control valve 210 is in an open state, which is convenient for transmitting the exhaled gas to the inside of the corresponding vertical cylinder 102, so as to realize the adjustment operation of the total exhaled gas volume for training.

[0031] Among them Figure 5-Figure 9 As shown, the air flow regulating mechanism 300 includes a fixed block 301 fixedly arranged on the outside of the air guide tube 103, a slide groove 302 is arranged inside the fixed block 301, a valve block 303 is slidably connected inside the slide groove 302, a screw rod 304 is arranged on the internal thread of the valve block 303, one end of the screw rod 304 extends to the outside of the fixed block 301 and is fixedly installed with a turning handle, and the user can drive the screw rod 304 to rotate by turning the turning handle, so that the valve block 303 will move up and down along the direction of the slide groove 302, thereby adjusting the distance between the valve block 303 and the bottom wall of the air guide tube 103, thereby adjusting the air guide tube 103. The amount of air that can pass through the interior is convenient for training the breathing volume per unit time. The screw 304 is rotatably connected to the fixed block 301. A wind sensor 305 is fixedly provided on the inner wall of the air duct 103 on the side close to the L-shaped support plate 101. A timer 306 is fixedly installed on the L-shaped support plate 101. The wind sensor 305 is electrically connected to the timer 306. When the wind sensor 305 detects wind or the wind stops flowing, the wind sensor 305 transmits a signal to the timer 306, so that the timer 306 performs a timing switch operation, and there is no need for the user to manually time, thereby improving the accuracy of training.

[0032] Among them Figure 2-Figure 6As shown, the collecting mechanism 400 includes a plurality of liquid outlet pipes 401 arranged inside the L-shaped support plate 101. When the user is training his vital capacity, he will train for many times and then clean the device. During this process, a large amount of saliva will be contained inside the vertical cylinder 102, which is easy to breed bacteria and is not convenient for moving the ball 201. An annular groove 402 is provided at the bottom of the vertical cylinder 102, and the inner wall of the annular groove 402 fits with the vertical cylinder 102, so that after multiple trainings, the saliva can flow through the inner wall of the vertical cylinder 102 to the inside of the annular groove 402, and then flow to the inside of the liquid outlet pipe 401 through the inclined surface, which is convenient for discharge. The upper end of the liquid outlet pipe 401 is connected to the annular groove 402, and the liquid outlet pipe The lower end of 401 extends to the outside of the L-shaped support plate 101 and is threadedly connected to the collecting bottle 403, which is convenient for disassembling the collecting bottle 403 for cleaning and avoiding the growth of more bacteria inside it. A bottom plate 404 is arranged below the L-shaped support plate 101 to play a supporting role. The bottom plate 404 is fixedly connected to the L-shaped support plate 101 through a connecting block. A plurality of grooves for placing the collecting bottle 403 are evenly distributed on the surface of the bottom plate 404. The collecting bottle 403 is in contact with the grooves but not fixed. The grooves play a supporting role. A first valve body 405 is fixedly arranged on the liquid outlet pipe 401 to facilitate controlling the opening and closing state of the liquid outlet pipe 401 to avoid affecting the training operation of the breathing gas.

[0033] Among them Figure 1-Figure 3 As shown, a handle 107 is fixedly mounted on one side of the L-shaped support plate 101, so that the user can move the device to other locations, making it easy to carry and increasing the overall practicality.

[0034] Among them Figure 1-Figure 3 As shown, the vertical cylinder 102 is set to a transparent material, and a scale bar is set on the surface of the vertical cylinder 102, so that the user can intuitively observe the up and down movement distance of the ball 201, and then compare it with the previous or subsequent training data, which is convenient for recording data and increasing the user's enthusiasm. The device can also be used for inhalation training. Just turn the device upside down so that the top plate 207 is at the bottom. Due to the influence of gravity, the switch component is in an open state and the shunt tube 105 is in an open state. When the user inhales, due to the pressure, the ball 201 moves toward the side of the shunt tube 105. By observing the relative position between the ball 201 and the scale bar, the training effect of inhalation can be known.

[0035] Among them Figure 8 and Fig. 9 As shown, the lower end of the valve block 303 is set to be arc-shaped, and the arc size of the valve block 303 is adapted to the arc size of the inner wall of the airway tube 103. The valve block 303 can adjust the amount of air that can pass through the airway tube 103, thereby achieving the need to adjust the exhalation flow per unit time during exhalation training.

[0036] Among them Figure 6As shown, the annular groove 402 is inclined toward one side of the liquid outlet pipe 401, and the inner wall of the annular groove 402 fits with the vertical cylinder 102, so that after multiple trainings, saliva can flow through the inner wall of the vertical cylinder 102 to the inside of the annular groove 402, and then flow through the inclined surface to the inside of the liquid outlet pipe 401 for easy discharge. Example 2

[0037] The difference from Example 1 is that Figure 1-Figure 3 As shown, a disinfectant tank 108 is provided above the handle 107, and the disinfectant tank 108 is fixedly mounted on the bracket, and a liquid infusion tube 109 is fixedly connected to the lower end of the disinfectant tank 108, and the other end of the liquid infusion tube 109 extends to the inside of the partition 106 and is connected to a plurality of liquid inlet tubes, and the other end of the liquid inlet tube extends to the inside of the vertical cylinder 102 and is fixedly connected to the push plate 202, and a second valve body 110 is provided on the liquid inlet tube. When the training is completed, the second valve body 110 is opened and the first valve body 405 is closed, so that the disinfectant in the disinfectant tank 108 can flow to the inside of the liquid inlet tube through the liquid infusion tube 109, and then be injected into the vertical cylinder 102, and the disinfectant flows on the inner walls of the vertical cylinder 102, the shunt tube 105, and the air guide tube 103, and then the water injection operation is performed to achieve the cleaning effect of the device.

[0038] When in use, the user first adjusts the pushing mechanism 200 and the air flow regulating mechanism 300 according to his own training needs. When the air flow needs to be adjusted, the user turns the handle to drive the screw 304 to rotate, so that the valve block 303 moves downward along the direction of the slide slot 302, and then adjusts the distance between the valve block 303 and the bottom wall of the air guide tube 103 to achieve the air flow regulation effect. When the exhalation pressure needs to be increased, a number of counterweights are placed in the placement slot 205 to increase the resistance of the ball 201 when pushing the push plate 202 to move upward, so as to achieve the regulation of the exhalation pressure. After the adjustment operation is completed, the breathing mask 10 Blow air into the airway 103, and the exhaled gas first reaches the first vertical cylinder 102, and then blows the ball 201 to move in the direction of the push plate 202. The ball 201 pushes the push plate 202 to move upward, and then drives the slide plate 204 to move on the limit column 206, so that the user can intuitively observe the training degree. When the exhaled volume in the first vertical cylinder 102 reaches the maximum value, the contact 208 contacts the control switch 209, and then the control switch 209 transmits a signal to the corresponding control valve 210, so that the exhaled gas enters the next vertical cylinder 102 through the shunt pipe 105, so as to realize the progressive training operation.

[0039] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
