DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 8 , the present invention provides the following technical solutions: Embodiment 1: The solution disclosed in this embodiment is to solve the problems existing in the prior art, and the solution is as follows Figure 1-Figure 2As shown, it includes a trainer body 1 and an exhalation tube 2 and a return air tube 3 connected to the trainer body 1, and also includes a valve 8 connected to each functional space inside the trainer body 1. The airflow in the output end of the above pipeline is unidirectional, and the head end is collected and connected to the breathing mask, and the output end of the exhalation tube 2 and the input end of the return air tube 3 are respectively connected to the exhalation space and the return air space in the trainer body 1, wherein the return air space is used to transport a specified airflow toward the mask, and the upper and lower parts of the exhalation space inside the trainer body 1 are respectively a movable plate 5 and a fixed horizontal plate 4, wherein the movable plate 5 is vertically elastically slidably installed in the trainer body 1 through an elastic member, and the exhalation drives the movable plate 5 to elastically slide to perform lung function training, and the trainer body 1 also includes a dehumidification mechanism, which removes water vapor and water droplets gathered in the exhalation space by moving the movable plate 5, and the dehumidification mechanism includes a transmission vertical rod 7 for generating power, wherein the transmission vertical rod 7 is rotatably installed on the movable plate 5. The bottom of the movable plate 5 slides through the center of the fixed horizontal plate 4, wherein the bottom end of the transmission vertical rod 7 is connected to the valve plate 6, and the return air space below the valve plate 6 is connected to the input end of the return air pipe 3, and the space above the valve plate 6 is a buffer space, which is connected to the input end of the one-way nozzle 9, and the top of the one-way nozzle 9 is distributed toward the inner wall of the exhalation space, wherein the input end of the exhalation tube 2 is connected to a mask or other respiratory equipment. During the patient's postoperative pulmonary function rehabilitation exhalation training, the gas is exhaled into the exhalation space through the exhalation tube 2. At this time, the movable plate 5 will be forced to move upward and compress the elastic part in the non-enclosed space above it, thereby generating exhalation resistance and thus achieving the training effect. In the process of the movable plate 5 moving upward, the transmission vertical rod 7 below it will drive the valve plate 6 to move synchronously, so the buffer space above it will be compressed accordingly, and in this process, the nozzle 9 blows airflow toward the inside of the trainer body 1, thereby reducing the generation of water droplets on the inner wall in this way.

[0022] Embodiment 2: The solution disclosed in this embodiment discloses another solution for preventing a large amount of water stains from forming on the inner wall of the training device body 1. Different from the single cleaning method in Embodiment 1, the content in this embodiment is as follows: Figure 3-6As shown, the dehumidification mechanism includes a cleaning rod 10 located in the breathing space, and the cleaning rod 10 is connected to the bottom end of another transmission vertical rod 7 through a hollow cross bar 12, and the bottom end of the transmission vertical rod 7 connected to the cleaning rod 10 is rotated and penetrated on the movable plate 5, and the top of the transmission vertical rod 7 above the movable plate 5 is also fixedly connected to a twisted rod, and the twisted rod threadedly passes through the inside of the trainer body 1, and an opening 11 is opened on the surface of the cleaning rod 10, and the opening 11 is connected to the connecting mechanism, wherein the outer end of the connecting mechanism is connected to a negative pressure or positive pressure device, and negative pressure is sucked out or high pressure is blown to clean water droplets on the inner wall of the trainer body 1 through the opening 11, and the opening 11 is connected to the internal space of the ring body 13 through the cleaning rod 10 and the internal cavity of the transmission vertical rod 7 above the movable plate 5, and the ring body 13 is rotatably installed on the surface of the transmission vertical rod 7 above the movable plate 5, and the ring body 13 is connected to the connecting pipe 14, wherein the ring body 13 and the connecting pipe 14 are connected by And the internal spaces of the transmission vertical rod 7 and the like together constitute a connecting mechanism. When the movable plate 5 is in the moving state, the twisted rod above it will synchronously move in the internal threaded mounting structure of the training device body 1. Therefore, under the action of the threaded transmission, the transmission vertical rod 7 itself will be in a rotating state. Therefore, the cleaning rod 10 connected to the middle section by the cross bar 12 will rotate synchronously to produce a scraping and cleaning effect. However, a single scraping will not fully process the water vapor. Therefore, the following content is also involved in this scheme. The internal designated section of the transmission vertical rod 7 is set as a hollow structure, and the ring body 13 rotatably mounted at its upper end can be used as a negative pressure or high pressure regulating component, and the specific regulating device is a pressure regulating device connected to the outside through the connecting pipe 14. In this way, under the conduction of the connecting pipe 14, the ring body 13, the internal space of the transmission vertical rod 7, the internal space of the cleaning rod 10 and the opening 11, the water vapor residue that may be generated in the exhalation space can be relatively thoroughly cleaned.

[0023] Embodiment 3: As a third implementation scheme, this scheme can be independently configured or used simultaneously with the above embodiment. Figure 7-Figure 8 In the scheme shown in the figure, the upper and lower sections of the transmission vertical rod 7 are integrated, and the lower half of the transmission vertical rod 7 is movably arranged on the fixed horizontal plate 4 and the valve plate 6. The surface of the transmission vertical rod 7 in the exhalation space is provided with a plurality of metal wires 15 distributed at equal angles. At the same time, the bottom end of the metal wire 15 passes through the interior of the transmission vertical rod 7 and diffuses and extends into the return air space, wherein the metal wire 15 is also used to conduct the heat in the exhalation space to the return air space. The rotation of the transmission vertical rod 7 is also used as the power source. The metal wire 15 located in the exhalation space adheres to and scrapes the inner wall of the exhalation space during the rotation process, thereby achieving the effect of auxiliary cleaning. As another effect, the metal wire 15 can be used as a heat conduction scheme to guide the heat generated by the exhalation and act on the return air space. In this way, when the patient uses the trainer to inhale, the inhaled air can be pre-heated, thereby avoiding throat discomfort caused by the directly inhaled air being too dry and cold.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
