[0057] Hereinafter, embodiments of the technical solutions of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0058] Embodiment:

[0059] Such as Figure 1 , 2, as shown in FIGS. 5, the present invention provides a portable pulmonary function rehabilitation trainer, which includes a housing. The housing includes a first housing 101 and a second housing 201. A breathing port 103 is provided on the first housing 101. A breathing mask 104 is provided on the first housing 101. The breathing mask 104 is communicated with the first housing 101 through the breathing port 103. A protective ring 105 is provided at an opening on one side of the breathing mask 104. An adjusting assembly for controlling the size of the breathing airflow is provided on the second housing 201.

[0060] This trainer is small and light, and patients can carry it with them for training. When using it, cover the breathing mask 104 over the mouth to breathe. The adjusting assembly includes a fixed cylinder 202 provided on the second housing 201. A plurality of groups of first ventilation grooves 203 are provided at one end of the fixed cylinder 202. A shielding cylinder 701 is rotatably provided in the fixed cylinder 202 along its axis. The shielding cylinder 701 contacts one end of the fixed cylinder 202. A plurality of groups of second ventilation grooves 703 are provided at one end of the shielding cylinder 701. A knob 702 is provided at one end of the shielding cylinder 701. The knob 702 is rotatably connected to the second housing 201.

[0061] During the breathing process, the gas flows in the first ventilation grooves 203, the second ventilation grooves 703 and the breathing port 103. By rotating the knob 702, the shielding cylinder 701 can be driven to rotate. The shielding of the first ventilation grooves 203 by the shielding cylinder 701 is used to control the flow rate of the gas flow, thereby generating a certain resistance to the patient's breathing and achieving the purpose of assisting the patient's pulmonary function rehabilitation exercise.

[0062] As Figure 1 、 4 shown, in this embodiment, a winding shaft 301 is rotatably provided in the housing along its axis. A water absorption belt 302 is wound on the winding shaft 301. The water absorption belt 302 shields the breathing port 103, and the water absorption belt 302 passes through a first through groove 102 on one side of the first housing 101. When the patient is performing breathing training, the water absorption belt 302 can also absorb saliva and gas generated during the breathing process, preventing saliva from entering the trainer and breeding bacteria.

[0063] As Figure 2 、 4 、6 to Figure 8 shown, in this embodiment, a driving mechanism is provided on the housing. The driving mechanism includes a transmission cylinder 502 that is rotatable along its axis. A shielding cover 106 is provided on the first housing 101. An installation cylinder 604 is provided on the shielding cover 106. The transmission cylinder 502 is rotatably provided in the installation cylinder 604 along its axis.

[0064] A transmission component for controlling the intermittent rotation of the transmission cylinder 502 is further provided on the housing. The transmission component includes a button 601. A positioning groove 605 extending along its axis is formed in the mounting cylinder 604. A positioning block 603 is provided on the periphery of the button 601, and the positioning block 603 is slidably clamped in the positioning groove 605. A transmission column 602 is provided on the button 601. A conduction groove 503 is formed in the transmission cylinder 502, and the transmission column 602 is slidably clamped in the conduction groove 503. Pressing the button 601 can control the one-way intermittent rotation of the transmission cylinder 502 through the conduction groove 503. An elastic member 606 is provided in the button 601 to control the reset of the button 601.

[0065] Press the button 601. The button 601 can slide up and down under the cooperation of the positioning groove 605 and the positioning block 603, thereby driving the transmission column 602 to slide up and down. The upper and lower surfaces of the conduction groove 503 are both annular serrated surfaces, and the upper and lower serrated surfaces are in a staggered state. In the initial state, the transmission column 602 is located at the M position on the upper inclined surface in the conduction groove 503. During the process of pressing the button 601, the transmission column 602 moves downward. After the transmission column 602 moves downward and contacts the lower inclined surface of the conduction groove 503, it slides along the lower inclined surface in the conduction groove 503 to control the rotation of the transmission cylinder 502. When the button 601 is pressed to the limit position, the transmission column 602 is located at the N position in the conduction groove 503. Then release the button 601. Under the action of the elastic member 606, the button 601 is controlled to reset, so that the transmission column 602 moves upward and contacts the upper inclined surface of the conduction groove 503, and drives the transmission cylinder 502 to rotate slightly through the upper inclined surface of the conduction groove 503. When the button 601 resets, the transmission column 602 is located at the O position in the conduction groove 503. Furthermore, the intermittent rotation of the transmission cylinder 502 by a certain angle can be controlled by pressing the button 601 once.

[0066] Such as Figure 4 、 6, as shown in FIGS. 7, in this embodiment, a conveying assembly is disposed inside the housing. The conveying assembly includes two sets of parallel drive shafts 304 spaced apart from each other. The drive shafts 304 are rotatably disposed inside the housing along their axes. A gap for the water absorption belt 302 to pass through is formed between the two sets of drive shafts 304. An acceleration assembly is disposed on the housing to increase the rotation speed of the drive cylinder 502 and transmit it to one of the drive shafts 304 to control its rotation for conveying the water absorption belt 302. The acceleration assembly includes a first transmission gear 306 fixedly disposed on one of the drive shafts 304 and coaxial with it. A coaxial second transmission gear 501 is disposed at the bottom of the drive cylinder 502. The second transmission gear 501 is rotatably connected to the first transmission gear 306. A rotatable first acceleration gear 401 is disposed on the housing. The first acceleration gear 401 meshes with the first transmission gear 306. A second acceleration gear 402 is fixedly disposed on the first acceleration gear 401. The second acceleration gear 402 meshes with the second transmission gear 501. The number of teeth of the second transmission gear 501 and the first acceleration gear 401 are respectively greater than the number of teeth of the second acceleration gear 402 and the first transmission gear 306.

[0067] During the process of pressing the button 601 to control the intermittent rotation of the drive cylinder 502, the second transmission gear 501 is driven to rotate, thereby driving the first acceleration gear 401 and the second acceleration gear 402 to rotate at an accelerated speed. And through the meshing of the first acceleration gear 401 and the first transmission gear 306, one of the drive shafts 304 is controlled to rotate at an accelerated speed. Since drive gears 305 are disposed at one ends of the two sets of drive shafts 304 and the two drive gears 305 mesh with each other, one of the drive shafts 304 can drive the other drive shaft 304 to rotate in the opposite direction simultaneously during the rotation process, so as to quickly convey the water absorption belt 302 through the frictional force of the two drive shafts 304, and the water absorption belt 302 adsorbed with saliva is moved out of the first through groove 102.

[0068] As Figure 1 , 2 , as shown in FIGS. 9, in this embodiment, a shearing mechanism for shearing the water absorption belt 302 is disposed inside the first housing 101. The shearing machine includes a shearing frame 803. The shearing frame 803 is slidably connected to the first housing 101 through a positioning post 805. A shearing knife 804 is disposed on the shearing frame 803. A shearing frame 806 communicating with the first through groove 102 is disposed inside the first housing 101. A second through groove 807 is formed on the shearing frame 806. A control assembly connected to the button 601 is disposed inside the first housing 101. The control assembly includes a connecting frame 801 which is disposed on the first housing 101 in a liftable manner. One end of the connecting frame 801 is fixedly connected to the button 601, and a control post 802 is disposed at the other end. An inclined groove 808 is formed on the shearing frame 803. The control post 802 is slidably clamped in the inclined groove 808 along the extending direction of the inclined groove 808.

[0069] While pressing the button 601, the connecting frame 801 is driven to move downward, thereby driving the control column 802 to move downward. One end of the positioning column 805 is fixedly connected to the first housing 101 to position the movement of the shearing frame 803. During the movement of the control column 802, the shearing knife 804 is driven to slide along the axis of the positioning column 805 into the second through groove 807 by cooperating with the inclined groove 808. And when the button 601 moves to the limit position, the water absorption belt 302 is cut off by the shearing knife 804, which is convenient for processing the used water absorption belt 302 extending out of the first through groove 102. It is not necessary for the patient to manually tear the used water absorption belt 302, nor is it necessary to use other shearing tools, which improves the convenience of the trainer during use.

[0070] As Figure 1 , 4 shown, in this embodiment, guiding shafts 303 that can rotate along the axis are provided at both ends of the first housing 101. A gap for the water absorption belt 302 to pass through is formed between the guiding shafts 303 and the first housing 101. The movement track of the water absorption belt 302 is guided by the guiding shafts 303, so that the water absorption belt 302 can be close to the breathing port 103, thereby better receiving saliva.

[0071] As Figure 3 shown, in this embodiment, a sealing frame 204 is provided in the second housing 201, a filter block 205 is provided in the sealing frame 204, a sealing ring 206 is provided at one end of the sealing frame 204, and the sealing ring 206 is in contact with the water absorption belt 302. Through the setting of the sealing ring 206 on one side of the sealing frame 204, the water absorption belt 302 is further made to fit the first housing 101, and at the same time, air can flow between the fixed cylinder 202 and the sealing frame 204, avoiding a large amount of external gas from entering the breathing port 103. The inhaled gas can be filtered by the filter block 205 to improve the effect of rehabilitation training.

[0072] As Figure 2 , 3 shown, one end of the second housing 201 is hinged to the first housing 101. The second housing 201 and the first housing 101 are connected by a buckle 207 in the closed state, and the gap between the second housing 201 and the first housing 101 is sealed by multiple groups of sealing strips 208. When the water absorption belt 302 is used up, the buckle 207 can be opened and the second housing 201 can be rotated and opened along its hinge point with the first housing 101 to facilitate the replacement of the winding shaft 301. The gap between the first housing 101 and the second housing 201 is sealed by the sealing strips 208 to prevent external air from entering, so as to improve the training effect.

[0073] The specific usage mode and beneficial effects of the present invention:

[0074] When the trainer is used, breathing is performed through the breathing port 103, and the saliva and gas generated during breathing are absorbed by the water absorption belt 302, so as to prevent the saliva from entering the inside of the trainer and breeding bacteria. When in use, the button 601 can be pressed, and the transmission cylinder 502 can be controlled to rotate intermittently on the first shell 101 through the cooperation of the transmission column 602 and the conduction slot 503. During the rotation of the transmission cylinder 502, one of the transmission shafts 304 is controlled to accelerate the intermittent rotation through the acceleration component, so that the two transmission shafts 304 are controlled to rotate in opposite directions at the same time through the meshing of the two driving gears 305, so as to pull the water absorption belt 302 to move in the first shell 101, so that the unused water absorption belt 302 moves to the breathing port 103, and the used water absorption belt 302 moves to the outside of the first through slot 102, so as to facilitate the treatment of the saliva generated during the breathing training process.

[0075] During the training process, the trainer uses the sealing frame 204 and the sealing ring 206 to resist one side of the water absorbent belt 302, so that the breathing port 103, the sealing frame 204 and the fixed cylinder 202 form a passage for the flow of breathing gas, and adjusts the exposed space of the first ventilation groove 203 by rotating the shielding cylinder 701 to adjust the resistance during breathing training. After long-term use, when the water absorbent belt 302 is finished, the second shell 201 can be opened to make the sealing strip 208 detach from the water absorbent belt 302 and release the fixation of the winding shaft 301, so that the winding shaft 301 can be disassembled and replaced with the winding shaft 301 with a new water absorbent belt 302 for installation, making lung function rehabilitation training more convenient and improving the practicality of the trainer.

[0076] When the button 601 is pressed, the connecting frame 801 can also be driven to move downward, thereby causing the control column 802 at the bottom of the connecting frame 801 to move downward. During the movement, the control column 802 cooperates with the inclined groove 808 to drive the shear knife 804 to slide into the second through groove 807 to cut the absorbent belt 302, thereby facilitating the disposal of the absorbent belt 302 after use. There is no need for the patient to manually tear off the absorbent belt 302 after use, nor is there any need to use other cutting tools, thereby improving the convenience of the trainer when in use.

[0077] The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
