The working principle is as follows: the cleaning liquid medicine is poured into the liquid medicine placing cavity 120 from the liquid adding port 13 in advance, and the stirring shaft 141 and the stirring blades 142 are driven to rotate by the operation of the stirring motor 14, so that the cleaning liquid medicine can be stirred, and the effect of subsequent cleaning is prevented from being influenced by the precipitation of the liquid medicine;

when the oral cavity is cleaned and used, the backrest angle of the backrest plate 200 can be adjusted by the extension and contraction of the electric telescopic rod 201 so as to adapt to the use requirements of patients; the mouth portion overflow prevention cover main body 16 is attached and worn on the oral cavity part of the patient through the fixed connecting band 163, the oral pipette 162 is inserted into the oral cavity of the patient, and the spray tube 151, the cleaning brush 152 and the liquid medicine ejection port 153 at the end portion of the spray cleaning head main body 15 are placed in the oral cavity of the patient through the opening of the mouth portion overflow prevention cover main body 16;

then the driving motor 8 is started to work and drive the first rotary disc 9 to rotate, the first rotary disc 9 rotates and drives the support rod 10, the second rotary disc 11 and the rotating shaft 12 to integrally rotate, the support rod 10 drives the second piston rod 103 to move left and right through the linkage matching of the second rotating ring 101 and the second linkage rod 102 when rotating, the rotating shaft 12 drives the first piston rod 123 to move left and right through the first rotating ring 121 and the first linkage rod 122 when rotating, and since the support rod 10 and the rotation shaft 12 are symmetrically arranged based on the center of the second rotation plate 11, the rotation of the support rod 10 and the rotation shaft 12 causes the first piston rod 123 and the second piston rod 103 to perform opposite side-to-side movements, that is, when the first piston rod 123 is moved to the left, the second piston rod 103 is moved to the right, so that the first piston 124 and the second piston 104 perform the opposite piston movements in the first negative pressure chamber 1230 and the second negative pressure chamber 1011, respectively;

when the first piston 124 moves to the left and the second piston 104 moves to the right, the first negative pressure chamber 1230 is in a negative pressure state, the first check valve 125 is opened, thereby causing the liquid medicine suction tube 126 to suck the liquid medicine from the liquid medicine placing chamber 120, when the first piston 124 moves rightward, the second piston 104 moves to the left, the air pressure in the first negative pressure chamber 1230 increases, the first check valve 125 closes, the second check valve 128 opens, so that the liquid medicine in the first negative pressure cavity 1230 is transported through the liquid medicine output pipe 127, the first hose 129, the spray rinsing head main body 15 and the spray rinsing pipe 151, and finally sprayed into the oral cavity of the patient from the liquid medicine nozzle 153 for spray rinsing, at the same time, the oral cavity can be cleaned by the washing brush 152, and at the same time, because the oral anti-overflow cover main body 16 is arranged, the overflow preventing case 162 prevents the overflow of the waste liquid while the waste liquid collecting funnel 161 is used to collect the waste liquid overflowing from the oral cavity;

meanwhile, the movement of the first piston 124 is opposite to that of the second piston 104, and similarly, when the first piston 124 moves to the right, the second piston 104 moves to the left, at this time, negative pressure is formed in the second negative pressure cavity 105, the third one-way valve 107 is opened, so that the oral pipette 164 inside the mouth portion anti-overflow cover main body 16 sucks waste liquid generated after cleaning in the oral cavity and waste liquid collected and overflowed through the anti-overflow shell 162 and the waste liquid collecting funnel 161 into the second negative pressure cavity 105 through the second hose 106 and the waste liquid suction pipe 108, when the first piston 124 moves to the left, the second piston 104 moves to the right, at this time, the pressure in the second negative pressure cavity 105 is increased, the third one-way valve 107 is closed to prevent the waste liquid from flowing back, the fourth one-way valve 109 is opened, so that the waste liquid sucked in the second negative pressure cavity 105 is discharged into the waste liquid collecting cavity 1011 through the waste liquid discharge pipe 1010 to be; through the reciprocating operation, can make the liquid medicine go on simultaneously to the inside spray rinsing clearance in oral cavity and the drainage operation to the waste liquid, avoided the patient to need oneself toward the trouble of exhaling the waste liquid outward, the waste liquid that has also avoided producing after washing the oral cavity causes the waste liquid excessive because unable effective drainage, pollute the problem of patient's face and operation treatment environment, also can prevent to cause further infection in patient's oral cavity because the waste liquid backward flow, thereby can effectively prevent the waste liquid overflow and prevent secondary pollution, patient and medical staff's use has been made things convenient for greatly.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
