A support plate 22 is installed inside the first box body 1 and the second box body 101. The support plate 22 is threadedly fastened to the surface of the air pump 23 by screws.

[0025] Furthermore, as Figure 4 and Figure 7As shown in the figure, a convenient replacement mechanism 3 is provided on the inner wall of the first box body 1 and the surface of the filter element 105. The inside of the convenient replacement mechanism 3 includes a telescopic spring 31, a groove 32, an arc-shaped card slot 33 and an arc-shaped card member 34. Grooves 32 are formed on the inner walls of the first box body 1. An arc-shaped card member 34 is arranged inside the groove 32. The arc-shaped card member 34 is slidably matched with the inner wall of the groove 32. Arc-shaped card slots 33 are formed on the surfaces of the filter element 105. The arc-shaped card slots 33 are engaged with the surfaces of the arc-shaped card members 34. Telescopic springs 31 are installed on the surfaces of the arc-shaped card members 34. One end of the telescopic spring 31 is fixed to the inner wall of the groove 32.

[0026] During implementation, the user pulls the filter element 105 downward. At this time, the filter element 105 presses the telescopic spring 31 inside the groove 32, causing the arc-shaped card member 34 to move away from the surface of the arc-shaped card slot 33, so as to pull out the filter element 105 from the inside of the first box body 1 and replace the filter element 105. After the replacement is completed, the user puts the filter element 105 into the inside of the first box body 1 and the second box body 101. Under the elastic force of the telescopic spring 31 inside the groove 32, the arc-shaped card member 34 is driven to automatically snap into the inside of the arc-shaped card slot 33. Under the combined action of the arc-shaped card member 34 and the arc-shaped card slot 33, the filter element 105 is installed inside the first box body 1 to realize the function of the suction device for conveniently replacing the filter element 105.

[0027] Furthermore, as Figure 6 and Figure 8 shown, an anti-misinsertion mechanism 4 is provided on the surface of the suction tube 103 and the inner wall of the hose 108. The inside of the anti-misinsertion mechanism 4 includes a positioning card slot 41, a positioning block 42, a gasket 43 and a sealing gasket 44. Positioning card slots 41 are formed on the inner walls of the hose 108. A gasket 43 is wrapped around the surface of the suction tube 103. A sealing gasket 44 is adhered to the surface of the gasket 43 away from the suction tube 103. The gasket 43 and the sealing gasket 44 are made of silicone and rubber materials respectively. Positioning blocks 42 for preventing the hose 108 from coming off are installed on the surfaces of the sealing gaskets 44. The positioning blocks 42 are engaged with the positioning card slots 41.

[0028] During implementation, when the user inserts the hose 108 onto the surface of the suction tube 103, the positioning block 42 automatically snaps into the corresponding positioning card slot 41. Under the engagement of the positioning block 42 and the positioning card slot 41, the hose 108 is prevented from coming off the surface of the suction tube 103. Under the combined action of the gasket 43 and the sealing gasket 44, the sealing performance between the hose 108 and the suction tube 103 is higher, so that the sputum will not leak during suction. At the same time, since there is only one suction tube 103 on the surface of the top plate 102, the patient can accurately insert the hose 108 onto the surface of the suction tube 103 to realize the function of preventing misinsertion of the suction device.

[0029] Working principle: When in use, first place the first box body 1 at the designated position. The user installs the top plate 102 on the surfaces of the first box body 1 and the second box body 101, so that the suction tube 103 on the surface of the fixing plate 21 moves above the top plate 102. At this time, the adjustment knob 109 on the surface of the fixing plate 21 also moves above the top plate 102. The user powers on the suction device through the wiring area 26. The user inserts the hose 108 onto the surface of the suction tube 103, and the other end of the hose 108 is inserted into the patient's oral cavity. By rotating the adjustment knob 109, the power of the fixing plate 21 is adjusted to adjust the suction force. Under the action of the suction tube on the surface of the air pump 23, a negative pressure environment is generated inside the first box body 1 and the second box body 101. Air enters the inside of the filter element 105 through the inlet 106, and then is discharged from the inside of the filter element 105 after being filtered by the filter element 105. Under the action of the filter element 105, the air entering the inside of the first box body 1 and the second box body 101 is filtered, and the dust in the air is filtered out, so that the sputum in the patient's mouth enters the inside of the collection bottle 25 through the hose 108 and the suction tube 103. Under the action of the collection bottle 25, the sputum is centrally collected. The user can conveniently pick up the first box body 1 and the second box body 101 by rotating the handle 104 on the surface of the second box body 101.

[0030] Subsequently, when the user inserts the hose 108 onto the surface of the suction tube 103, the positioning block 42 is automatically installed inside the corresponding positioning slot 41. Under the clamping action of the positioning block 42 and the positioning slot 41, the hose 108 is prevented from loosening from the surface of the suction tube 103. Under the combined action of the gasket 43 and the sealing gasket 44, the sealing performance between the hose 108 and the suction tube 103 is higher, so that the sputum will not leak during suction. At the same time, since there is only one suction tube 103 on the surface of the top plate 102, the patient can accurately insert the hose 108 onto the surface of the suction tube 103 to realize the function of preventing misinsertion of the suction device, so that it is convenient for the user to insert the hose 108 onto the surface of the suction tube 103 when using the suction device, making the suction device more convenient to operate.

[0031] Subsequently, the filter element 105 needs to be disassembled and replaced after being used for a long time to avoid affecting the normal use of the sputum suction device. When the user needs to replace the filter element 105, the user pulls the filter element 105 downward. At this time, the filter element 105 squeezes the telescopic spring 31 inside the groove 32, so that the arc-shaped clamping member 34 is away from the surface of the arc-shaped clamping groove 33, thereby pulling the filter element 105 out of the first box body 1 and replacing the filter element 105. After the replacement is completed, the user puts the filter element 105 into the first box body 1 and the second box body 1 01, under the elastic force of the telescopic spring 31 inside the groove 32, the arc-shaped clamp 34 is automatically clamped into the arc-shaped clamping groove 33, and the filter element 105 is installed in the first box body 1 under the joint action of the arc-shaped clamp 34 and the arc-shaped clamping groove 33, so as to realize the function of convenient replacement of the filter element 105 of the sputum suction device, so that when the sputum suction device is used, it is convenient for the user to pull out the filter element 105 from the inside of the first box body 1, replace the filter element 105, which is more practical and finally completes the use of the sputum suction device.

[0032] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
