The air source connector 31 and the sand pot part 33 are fixed on the outside of the upper shell 5 , and the air circuit solenoid valve group 32 is fixed on one side of the upper shell 5 .

[0039] The water circuit heater 25 includes a heating shell 251, a heating element 257, a temperature sensor 255, a temperature fuse 256, a water inlet 253 and a water outlet 254; the heating shell 251 is installed in the lower shell 6, the heating element 257, the temperature sensor 255 and the temperature fuse 256 are all installed inside the heating shell 251, and are respectively connected to the main control board 7 through wires, the water inlet 253 is connected to the water pump in parallel with the water circuit solenoid valve 27, and the water outlet 254 is installed on the side of the temperature sensor 255 close to the water inlet 253.

[0040] The water supply assembly 2 also includes a water circuit solenoid valve 4 30 and a sandblasting handle 4. The water circuit solenoid valve 4 30 is installed between the water pump 1 22 and the water bottle 21. The sandblasting handle 4 is connected to the water circuit solenoid valve 2 28 through a pipeline, and is connected to the sand tank component 33 through a pipeline.

[0041] In this embodiment, the touch screen 10, the main control board 7, the power supply 8 and the foot pedal interface 9 are connected to the water circuit solenoid valve 1 27, the water circuit solenoid valve 2 28, the water circuit solenoid valve 3 29, the water circuit solenoid valve 4 30, and the air circuit solenoid valve group 32 through wires to control the opening and stopping of the water circuit and air circuit of the entire sandblasting and cleaning system.

[0042] After the high-pressure gas is connected from the gas source connector 31, it enters the gas circuit solenoid valve group 32, and then connects to the sand pot part 33. The high-pressure gas drives the sand powder particles in the sand pot part 33, connects with the sandblasting handle 4 through the pipeline, and finally sprays out from the sandblasting handle 4.

[0043] The heating element 257 can provide a heat source, the temperature sensor 255 can control the water temperature, and the temperature fuse 256 can provide insurance for the entire heater to prevent other risks caused by excessive temperature. The water inlet 1 253 is connected to the water pump 1 22 and connected in parallel with the water circuit solenoid valve 1 27, and the external water source of the sandblasting and cleaning system enters the water circuit heater 25 through the water inlet 1 253.

[0044] After the touch screen 10 is set to turn on the zero cold water function, there are two situations: water supply from the water bottle 21 and water supply from the external water source 24.

[0045] Case 1: When the water bottle 21 is set to supply water from the touch screen 10: the water circuit solenoid valve 1 27 and the water circuit solenoid valve 2 28 are closed, the water circuit solenoid valve 3 29, the water circuit solenoid valve 4 30, and the water pump 1 22 are opened, and the water in the water circuit heater 25 or the water bottle 21 will flow under the action of the water pump 1 22 and pass through the water outlet 254 of the water circuit heater 25, the water circuit solenoid valve 3 29, the water flow sensor 26, the water pump 1 22 and the water inlet 1 253 in sequence to return to the inside of the water circuit heater 25 to form a loop.

When the instrument pedal is stepped on, the water circuit solenoid valve 2 28, the water circuit solenoid valve 4 30 and the water pump 1 22 are opened by controlling the internal circuit, and the water circuit solenoid valve 1 27 and the water circuit solenoid valve 3 29 are closed. Hot water will flow out directly from the sandblasting handle 4, achieving zero cold water output, solving the problem that existing equipment easily causes discomfort to customers due to too low water temperature when cleaning teeth. At this time, the heating element 257 is still turned on to ensure that the cold water entering the water circuit heater 25 can continue to heat up. The touch screen 10 can be set to turn off the zero cold water function or turn off the power supply 8, thereby turning off the heating element 257 and stopping heating. Schematic diagram reference Figure 5 .

[0046] Case 2: When the touch screen 10 is provided with an external water source 24 for water supply: the water circuit solenoid valve 4 30, the water circuit solenoid valve 2 28, and the water pump 1 22 are closed, the water circuit solenoid valve 1 27, and the water circuit solenoid valve 3 29 are opened, and the water supply from the external water source 24 will enter the water circuit heater 25 under the action of the external high water pressure, flow and sequentially pass through the water outlet 254 of the water circuit heater 25, the water circuit solenoid valve 3 29, the water flow sensor 26, the water pump 1 22, and the water inlet 1 253 and return to the inside of the water circuit heater 25, forming a loop. When the water flow sensor 26 detects that water is passing through, it will trigger the water circuit solenoid valve 1 27 to close, and at the same time trigger the water pump 1 22 and the heating element 257 to open, and the water in the water circuit will quickly heat up to a comfortable temperature for the human body. When the instrument pedal is stepped on, the water circuit solenoid valve 1 27 and water circuit solenoid valve 2 28 are opened by controlling the internal circuit, and the water circuit solenoid valve 3 29, water circuit solenoid valve 4 30 and water pump 1 22 are closed. Hot water will flow out directly from the sandblasting handle 4, and zero cold water can be discharged, solving the problem that the existing equipment is prone to cause discomfort to customers due to too low water temperature when cleaning teeth. At this time, the heating element 257 is still turned on to ensure that the cold water entering the water circuit heater 25 can continue to heat up.

[0070] In this embodiment, the touch screen 10, the main control board 7, the power supply 8 and the foot pedal interface 9 are connected to the water circuit solenoid valve 1 27, the water circuit solenoid valve 2 28, the water circuit solenoid valve 3 29, the water circuit solenoid valve 4 30, and the air circuit solenoid valve group 32 through wires to control the opening and stopping of the water circuit and air circuit of the entire sandblasting and cleaning system.

[0071] After the high-pressure gas is connected from the gas source connector 31, it enters the gas circuit solenoid valve group 32, and then connects to the sand pot part 33. The high-pressure gas drives the sand powder particles in the sand pot part 33, connects with the sandblasting handle 4 through the pipeline, and finally sprays out from the sandblasting handle 4.

[0072] The heating element 257 can provide a heat source, the temperature sensor 255 can control the water temperature, and the temperature fuse 256 can provide insurance for the entire heater to prevent other risks caused by excessive temperature. The water inlet 1 253 is connected to the water pump 1 22 and connected in parallel with the water circuit solenoid valve 1 27, and the external water source of the sandblasting and cleaning system enters the water circuit heater 25 through the water inlet 1 253.

[0073] The sandblasting handle 4 has a handle tail seat 42, and there are two situations for the rear end water circuit: first, a blind hole handle 41 matching the handle tail seat 42 is installed, the water outlet 421 is communicated with the water inlet 422, and the water inlet 422 is connected to the water pipe 122 in the tail line assembly 12, and the water pipe 122 is then connected to the water circuit solenoid valve three 29, and the water passes through the water circuit solenoid valve three 29, and then is connected to the water flow sensor 26, and then passes through the water pump two 22, and finally connected to the water inlet one 253 of the water circuit heater 25 to enter the water circuit heater 25, so as to realize the water circuit loop;

[0074] Secondly, install a through-hole handle 43 that matches the handle tail seat 42, and install a sealable silicone plug 44 at the water inlet hole 422 of the handle tail seat 42, which can seal and separate the water outlet hole 421 from the water inlet hole 422. At this time, after water comes out of the water outlet hole 421, it finally flows out through the through-hole handle 43.

[0075] After installing the blind hole handle 41 matching the handle tail seat 42 and turning on the zero cold water function from the touch screen 10 , there are two situations at this time: water supply from the water bottle 21 and water supply from the external water source 24 .

[0076] In case 1, when the water bottle 21 is set to supply water from the touch screen 10: the water circuit solenoid valve 1 27 is closed, the water circuit solenoid valve 2 28, the water circuit solenoid valve 3 29, the water circuit solenoid valve 4 30, and the water pump 2 22 are opened, and the water in the water circuit heater 25 or the water bottle 21 will flow under the action of the water pump 22 and pass through the water outlet 254 of the water circuit heater 25, the water circuit solenoid valve 2 28, the water pipe 121, the handle tail seat 42, the blind hole handle 41, the handle tail seat 42, the water pipe 122, the water circuit solenoid valve 3 29, the water flow sensor 26, the water pump 2 22 and the water inlet 1 253 to return to the inside of the water circuit heater 25, forming a loop. When the water flow sensor 26 detects that water is passing through, it will trigger the water circuit solenoid valve 4 30 to close, and at the same time trigger the heating element 257 to open, and the water in the water circuit will quickly heat up to a comfortable temperature for the human body. When the sandblasting function is needed, a sealable silicone plug 44 is installed at the water inlet hole 422 of the handle tail seat 42, and the blind hole handle 41 is replaced with a through hole handle 43. When the instrument pedal is stepped on, the water circuit solenoid valve 28, the water circuit solenoid valve 430 and the water pump 22 are opened by controlling the internal circuit, and the water circuit solenoid valve 1 27 and the water circuit solenoid valve 3 29 are closed. Hot water will directly enter the through hole handle 43 from the water outlet hole 421 of the handle tail seat 42 and flow out, which can achieve zero cold water outlet, solving the problem that the existing equipment is prone to cause discomfort to customers due to too low water temperature when cleaning teeth. At this time, the heating element 257 is still on to ensure that the cold water entering the water circuit heater 25 can continue to heat up. The touch screen 10 can be set to turn off the zero cold water function or turn off the power supply 8, thereby turning off the heating element 257 and stopping heating.

[0077] In case 2, when the touch screen 10 is provided with an external water source 24 for water supply: the water circuit solenoid valve 4 30 and the water pump 2 22 are closed, the water circuit solenoid valve 1 27, the water circuit solenoid valve 2 28 and the water circuit solenoid valve 3 29 are opened, and the water supply from the external water source 24 enters the water circuit heater 25 under the action of the external high water pressure, flows and passes through the water outlet 254 of the water circuit heater 25, the water circuit solenoid valve 2 28, the water pipe 121, the handle tail seat 42, the blind hole handle 41, the handle tail seat 42, the water pipe 122, the water circuit solenoid valve 3 29, the water flow sensor 26, the water pump 2 22 and the water inlet 1 253 to return to the inside of the water circuit heater 25, forming a loop. When the water flow sensor 26 detects that water is passing through, it will trigger the water circuit solenoid valve 1 27 to close, and at the same time trigger the water pump 2 22 and the heating element 257 to open, and the water in the water circuit will quickly heat up to a comfortable temperature for the human body. When the sandblasting function is needed, a sealable silicone plug 44 is installed at the water inlet hole 422 of the handle tail seat 42, and the blind hole handle 41 is replaced with a through hole handle 43. When the instrument pedal is stepped on, the water circuit solenoid valve 1 27 and the water circuit solenoid valve 2 28 are opened by controlling the internal circuit, and the water circuit solenoid valve 3 29, the water circuit solenoid valve 4 30 and the water pump 2 22 are closed. Hot water will directly enter the through hole handle 43 from the water outlet hole 421 of the handle tail seat 42 and flow out, which can achieve zero cold water outlet, solving the problem that the existing equipment is prone to cause discomfort to customers due to too low water temperature when cleaning teeth. At this time, the heating element 257 is still on to ensure that the cold water entering the water circuit heater 25 can continue to heat up. The touch screen 10 can be set to turn off the zero cold water function or turn off the power supply 8, thereby turning off the heating element 257 and stopping heating.
