[0017] The present invention has the following beneficial effects:

[0018] The present invention is provided with a cleaning mechanism. First, the suction device is started to extract air from the inner wall of the base through the negative pressure tube, so that negative pressure is generated inside the liquid storage tank. At the same time, the suction tube is placed in the oral cavity of the patient. The sputum in the patient's body is sucked into the liquid storage tank through the negative pressure inside the liquid storage tank. It needs to be filtered through the coarse filter plate and the fine filter plate. When too much sputum is collected on the surface of the coarse filter plate and the fine filter plate, it needs to be cleaned. At this time, the motor is started to drive the rotating shaft to rotate. When the rotating shaft rotates, it drives the rotating ring to rotate, thereby driving the rotating plate to rotate at the same time through the rotating ring. At this time, the cleaning plate will rotate with the end of the rotating plate. When the cleaning plate rotates, it drives the cleaning brush to rotate. During the rotation of the brush, the inner wall of the liquid storage tank will be cleaned, thereby removing impurities on the inner wall of the liquid storage tank. When the cleaning plate rotates, the curved plate and the scraper will be driven to rotate. When the scraper rotates, it will scrape the inner wall of the liquid storage tank, thereby scraping off impurities on the inner wall of the liquid storage tank. The scraped impurities will enter the inner wall of the guide groove through the thrust of the rotation of the scraper, and then flow downward along the guide groove. Finally, the impurities will be guided to the surface of the coarse filter plate and the fine filter plate through the drainage pipe. The inner wall of the liquid storage tank is effectively cleaned by the cleaning brush, and the inner wall of the liquid storage tank is scraped by the scraper to scrape off the remaining impurities, thereby saving the labor of the staff and improving the cleaning efficiency.

[0019] The present invention is provided with a cleaning mechanism. When the cleaning brush and the scraper clean the inner wall of the liquid storage tank, the water pump is started to extract the cleaning liquid on the inner wall of the water storage tank through the water suction pipe, and then the cleaning liquid is sent into the inside of the annular pipe through the water inlet pipe. After entering the annular pipe, the cleaning liquid is sprayed on the inner wall of the liquid storage tank through the spray pipe, thereby flushing the inner wall of the liquid storage tank, thereby achieving the effect of cleaning again and making the inner wall of the liquid storage tank cleaner. When the cleaning plate rotates, it drives the driven rotating rod to rotate. When the driven rotating rod rotates, it drives the focusing plate to rotate, thereby cleaning the surface of the coarse filter disc and the fine filter disc, concentrating the impurities on the surfaces of the coarse filter disc and the fine filter disc, and concentrating the impurities scraped off by the scraper together, and effectively spraying the cleaning liquid evenly on the inner wall of the liquid storage tank through the spray pipe, so that the inner wall of the liquid storage tank is cleaner, and then the impurities scraped off the inner wall of the liquid storage tank and the impurities on the surfaces of the coarse filter disc and the fine filter disc are concentrated.

[0020] The present invention provides a collecting mechanism, and when the rotating shaft rotates, the slider and the passive rod rotate at the same time. When the rotating plate and the cleaning plate rotate, the lower push rod, the lower slider and the collecting rod rotate at the same time. When the driven rotating rod rotates, the collecting cylinder 1 and the collecting cylinder 2 rotate at the same time on the inner walls of the coarse filter disc and the fine filter disc, and the pushing plate is also driven to rotate. When the rotating plate rotates, the centrifugal force of the rotation speed causes the slide plate to slide on the inner wall of the groove toward each other. When the slide plate slides, the passive rod moves in the direction away from each other. At the same time, the passive rod pulls the slider to slide upward on the inner wall of the slide groove. When the slide slides, it pushes the lower push rod downward. At this time, the lower push rod pushes the lower slider to slide downward on the inner wall of the slide groove. The movable collecting rod moves in the direction of approaching each other, and pushes the pushing plate to move in the direction of approaching each other. When the pushing plate moves, it pushes the impurities concentrated on the collecting plate in the direction of approaching each other. In the process of pushing the impurities, the impurities will contact the surface of the sealing door. At this time, the sealing door will open in the direction of approaching each other when it is pushed, thereby pushing the impurities to the inner walls of the collecting barrel 1 and the collecting barrel 2. When the impurities enter the inner wall of the collecting barrel 1, they will fall into the interior of the collecting barrel 2 through the guide pipe, and then the impurities will fall into the inner wall of the focusing funnel through the discharge pipe, and finally the impurities will be discharged through the drain pipe, effectively cleaning and storing the impurities on the inner wall of the liquid storage tank and the surface of the coarse filter plate and the fine filter plate, and finally the impurities will be discharged, thereby improving the cleaning efficiency.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the rotating plate 13 and the cleaning plate 14 rotate, they will drive the lower push rod 54 and the lower push rod 56 to rotate. The block 55 and the collecting rod 56 rotate at the same time.

When the rotating plate 13 rotates, the centrifugal force of the rotation speed causes the slide plate 53 to slide on the inner wall of the groove in the direction of approaching each other. When the slide plate 53 slides, it pulls the passive rod 52 to move in the direction of moving away from each other. At the same time, the passive rod 52 pulls the slider 51 to slide upward on the inner wall of the chute. When the slide plate 53 slides, it pushes the lower push rod 54 to move downward. At this time, the lower push rod 54 pushes the lower slider 55 to slide downward on the inner wall of the chute. When the lower slider 55 slides, it pushes the collecting rod 56 to move in the direction of approaching each other.The push plate 57 is pushed toward each other. When the push plate 57 moves, it pushes the impurities collected by the collecting plate 38 toward each other. In the process of pushing the impurities, the impurities will come into contact with the surface of the sealing door 59. At this time, the sealing door 59 will open in the direction of approaching each other when it is pushed, thereby pushing the impurities to the inner walls of the collecting tube 1 58 and the collecting tube 2 61. When the impurities enter the inner wall of the collecting tube 1 58, they will fall into the interior of the collecting tube 2 61 through the guide pipe 60.
