The working principle of the handle boot 300 of the present embodiment in use is exemplified as follows:

if ultrasonic cleaning is required, after the tail water pipe 380, the tail air pipe 390 and the lead 370 are communicated with the host, electric energy at the host end is led into the handle tail sleeve 300 by the two leads 370 to be connected with the two pins 360 inserted on the fixed block 320, the pins 360 are inserted into the socket 170 to be correspondingly connected with the welding pins 160 at the bottom of the transducer 120, so that the electric energy is transmitted to the transducer 120, the transducer 120 converts the electric energy into mechanical kinetic energy, and the cleaning tip is pushed by ultrasonic waves; the water enters the water pipe joint 350 from the tail water pipe 380, is guided to the water inlet 3310 of the diversion valve 330 by the water pipe joint 350, flows into the socket 170, the water inlet joint 140, the water hose 150 and the central hole of the transducer 120 from the water outlet 3320 in sequence after passing through the water flow channel 334 formed between the through hole 333 of the diversion valve 330 and the air pipe joint 340, and is then conducted to the cleaning tip. Along with the vibration of the cleaning work tip, the water is atomized, and the vibrating cleaning work tip stretches into the oral cavity, so that the ultrasonic cleaning effect is realized.

If sand blasting is required, after the tail water pipe 380, the tail air pipe 390 and the lead 370 are communicated with the host, compressed air is pumped into the air pipe joint 340 from the tail air pipe 390, and is transported to the pipe core of the spray head 220 through the air outlet 221 of the spray head 220 after passing through the butt joint pipe 260 and the spray head air pipe 230, and then sprayed; the water liquid enters the water pipe joint 350 from the tail water pipe 380, is guided to the water inlet 3310 of the flow guiding valve 330 by the water pipe joint 350, flows into the shunt pipe 280, the water pipe 270, the sand blasting handle rear end 250 and the nozzle connecting piece 240 from the water outlet 3320 after passing through the flow guiding valve 330, flows into the second water outlet 223 after flowing through the first water outlet 222 of the nozzle 220, is converged with the sand-carrying air source outside the nozzle 220 and acts on the tooth surface of a patient, and achieves the effect of sand blasting cleaning.

In summary, the present embodiment discloses a handle boot 300 and an ultrasonic sand blasting apparatus, wherein the handle boot 300 includes a boot housing 310, a fixing block 320, a diverter valve 330, a water pipe connector 350, an air pipe connector 340 and a pin 360. The fixed block 320 is provided with a mounting hole 321 in the tail sleeve shell 310, the guide valve 330 is fixedly arranged in the mounting hole 321 in a penetrating manner and extends towards one end of the tail sleeve shell 310, the guide valve 330 is provided with a through hole 333, a water inlet 3310 and a water outlet 3320, the water inlet 3310 is close to the second end 312, the water outlet 3320 is close to the first end 311, the water pipe connector 350 is inserted into the water inlet 3310, the air pipe connector 340 is fixedly arranged in the through hole 333 in a penetrating manner, a water flow channel 334 is formed between the outer peripheral wall of the air pipe connector 340 and the inner peripheral wall of the through hole 333, and the water inlet 3310 and the water outlet 3320 are both communicated with the water flow channel 334; the pin 360 is inserted into the fixing block 320 toward the first end 311.

Thus, when the ultrasonic handle 100 or the blast handle 200 is inserted into the diverter valve 330, the water flowing through the water inlet 3310 flows out of the water outlet 3320 through the water flow channel 334 to be input into the ultrasonic handle 100 or the blast handle 200, thereby supplying water to both types of handles of the blast handle 200 and the ultrasonic handle 100 through one handle tail cover 300. Because the pin 360 is disposed on the side of the fixing block 320 facing the first end 311, when the ultrasonic handle 100 is connected with the handle tail shell, the pin 360 can be connected with the welding pin 160 at the bottom of the transducer 120 on the ultrasonic handle 100, so as to supply power to the transducer 120, so that the electric energy is converted into mechanical kinetic energy through the transducer 120, and the cleaning tip is pushed by ultrasonic waves to perform the tooth cleaning effect. Because the air pipe joint 340 is fixedly arranged in the through hole 333 in a penetrating way, the air pipe joint 340 is connected with the sand conveying pipeline of the sand blasting handle 200, thereby realizing sand powder conveying, cleaning teeth through sand blasting, realizing that the ultrasonic handle 100 and the sand blasting handle 200 share the same handle tail sleeve 300, and only needing to replace the corresponding handle to be connected with the handle tail sleeve 300 when ultrasonic or sand blasting cleaning is needed, the use is more convenient, the parts in a host can be reduced, the occupied space of the host is reduced, the manufacturing cost is reduced, and meanwhile, the ultrasonic sand blasting equipment is integrally miniaturized, and the space utilization rate is improved.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
