[0008] Among them, the disinfection mechanism includes a mounting frame installed on the top of the dental chair body, and a mounting plate is arranged inside the top of the mounting frame, and an electric telescopic rod is installed on one side of the bottom end of the mounting plate, and a toothed plate is installed on the output end of the electric telescopic rod, and the bottom end of the mounting plate is symmetrically rotatably connected with a gear, and the bottom end of the mounting plate is symmetrically rotatably connected with a half-toothed disc, and the toothed plate, the gear and the half-toothed disc are meshingly connected, and one end of the half-toothed disc is fixedly connected with a hollow box, and the bottom end of the hollow box is fixedly connected with a first atomizing nozzle, and a first hose is installed inside one side of the hollow box, and a water box is installed on the top of the mounting frame, and the top end of the first hose passes through the mounting frame and is fixedly connected with the water box.

[0009] Preferably, a transmission pipe is installed at one end of the mounting frame, and the top end of the transmission pipe is fixedly connected to the water box, and a fixed pipe is installed at the bottom end of the transmission pipe, and the bottom end of the fixed pipe is fixedly connected to a second hose, and a blocking block is snap-connected inside the bottom end of the fixed pipe, and sliding grooves are symmetrically provided on both sides of the interior of the fixed pipe, and a moving rod is fixedly connected to the top end of the blocking block, and both ends of the moving rod are slidably connected to the sliding groove, and telescopic springs are symmetrically provided between the two ends of the moving rod and the sliding groove.

[0010] Preferably, the moving assembly includes a first sliding box installed on one side of the dental chair body, and the first sliding box is rotatably connected to a screw rod inside, and the outer side of the screw rod is threadedly connected to a first moving block, and a forward and reverse motor is installed at one end of the screw rod, and a second sliding box is installed on the side of the dental chair body away from the first sliding box, and a support rod is installed inside the second sliding box, and the outer side of the support rod is slidably connected to a second moving block, and the two ends of the bottom of the mounting frame are fixedly connected to the first moving block and the second moving block.

[0013] Preferably, one side of the forward and reverse motor is fixedly connected to the first sliding box.

[0014] Preferably, the top end of the tooth plate is slidably connected to the mounting plate.

[0015] Compared with the prior art, the beneficial effect of the utility model is as follows: the air disinfection type dental chair with unidirectional drainage is specifically designed as follows: through the cooperation between the tooth plate, the gear and the semi-tooth plate, the two groups of hollow boxes are driven to perform intermittent arc trajectory reciprocating operation, thereby driving multiple groups of first atomizing nozzles to spray disinfectant water on the surface of the dental chair body in a large range and evenly. The disinfectant water diffuses in the form of atomization, which can not only cover and disinfect the surface of the dental chair body, but also disinfect the air on the top of the dental chair body to a certain extent during the falling process, thereby improving the subsequent disinfection efficiency of the dental chair body. The first moving block is driven to slide inside the first sliding box through the rotation of the screw, and then the second moving block at the bottom end of the mounting frame slides inside the second sliding box. At this time, the second moving block slides on the support rod, thereby achieving the effect of adjusting the position of the mounting frame, thereby enabling the position of the disinfection mechanism to be adjusted, thereby greatly increasing the spraying range of the disinfection mechanism, thereby further improving the surface disinfection effect of the dental chair body.

[0016] 1. The tooth plate is driven to move back and forth on the mounting plate by starting the retracting rod, and the gear is driven to rotate through the tooth plate. The rotation of the gear drives the half tooth plate to rotate back and forth, thereby driving the two sets of hollow boxes to perform intermittent arc trajectory reciprocating operation, thereby driving multiple sets of first atomizing nozzles to spray disinfectant water evenly over a large area on the surface of the dental chair body. The disinfectant water diffuses in the form of atomization, which can not only cover and disinfect the surface of the dental chair body, but also disinfect the air on the top of the dental chair body to a certain extent during the falling process, thereby improving the subsequent disinfection efficiency of the dental chair body, thereby bringing convenience to the staff when using it. Through the design of the second atomizing nozzle, the dental chair body can be close to the backrest. The surface of one side can also be uniformly disinfected. When the disinfectant water is transmitted inside the transmission pipe, the disinfectant water squeezes the block, and then the block drives the moving rod to slide inside the slide groove, thereby squeezing the telescopic spring. When the disinfectant water does not flow inside the transmission pipe, the resetting property of the telescopic spring allows the block to re-engage with the internal seal of the bottom end of the fixed pipe, thereby effectively preventing the disinfectant water from flowing back inside the transmission pipe. The one-way channel anti-backflow structure can effectively prevent the disinfectant water from flowing back and contaminating the disinfectant in the disinfection box, causing it to lose its original disinfection effect or even become a pollution source, thereby ensuring the normal operation and effective disinfection of the device, and bringing convenience to the staff when using it;

[0017] 2. By starting the forward and reverse motors to drive the rotation of the screw, the rotation of the screw drives the first moving block to slide inside the first sliding box. At this time, the first moving block drives the movement of the mounting frame, thereby causing the second moving block at the bottom of the mounting frame to slide inside the second sliding box. At this time, the second moving block slides on the support rod, thereby achieving the effect of adjusting the position of the mounting frame, thereby enabling the position of the disinfection mechanism to be adjusted, thereby greatly increasing the spraying range of the disinfection mechanism, thereby further improving the disinfection effect on the surface of the dental chair body, and bringing convenience to the staff when using it.

[0032] Working principle: Before using this one-way drainage air disinfection dental chair, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 8 As shown, by starting the electric telescopic rod 203, the tooth plate 204 is driven to move back and forth on the mounting plate 202, and then the tooth plate 204 drives the rotation of the gear 205, and the rotation of the gear 205 drives the reciprocating rotation of the semi-toothed disc 206, thereby driving the two groups of hollow boxes 207 to perform intermittent arc trajectory reciprocating operation, thereby driving multiple groups of first atomizing nozzles 208 to spray disinfectant water on the surface of the dental chair body 101 in a large range and uniformly. The disinfectant water diffuses in the form of atomization, which can not only cover and disinfect the surface of the dental chair body 101, but also disinfect the air on the top of the dental chair body 101 to a certain extent during the falling process, thereby improving the subsequent disinfection efficiency of the dental chair body 101, thereby bringing convenience to the staff when using it.

When the disinfectant water does not flow in the transmission pipe 2111, the resetting property of the telescopic spring 217 allows the block 214 to be re-sealed with the bottom of the fixed pipe 212, thereby effectively preventing the disinfectant water from flowing back in the transmission pipe 2111. The one-way channel anti-backflow structure can effectively prevent the disinfectant water from flowing back and contaminating the disinfectant in the disinfection box 103, causing it to lose its original disinfection effect or even become a pollution source, so as to ensure the normal operation and effective disinfection of the device, and bring convenience to the staff when using it;

[0033] By starting the forward and reverse motor 304 to drive the screw 302 to rotate, the rotation of the screw 302 drives the first moving block 303 to slide inside the first sliding box 301. At this time, the first moving block 303 drives the movement of the mounting frame 201, thereby making the second moving block 306 at the bottom of the mounting frame 201 slide inside the second sliding box 3051. At this time, the second moving block 306 slides on the support rod 305, so that the position of the mounting frame 201 can be adjusted, so that the position of the disinfection mechanism 2 can be adjusted, thereby greatly increasing the spraying range of the disinfection mechanism 2, thereby further improving the surface disinfection effect of the dental chair body 101, and bringing convenience to the staff when using it.
