Wherein, the controller 600 is configured to:

Receive the first signal continuously sent by the first trigger part 310 in the state of continuous triggering, and receive the second signal sent by the second trigger part 320 being triggered instantaneously, and record the current distance sent by the distance sensor 400 The value is used as the starting distance of the pump, and the starting distance of the pump is the sensing height;

After receiving the distance value sent by the distance sensor 400 equal to the starting distance of the pump, a working signal is sent to the pump 500.

Specifically, the model of the controller is FT61F022A-RB.

Further, the first trigger part 310 is a power charging interface; specifically, the first trigger part 310 is a USB interface.

Further, the second trigger part 320 is a touch button.

It should be noted that the battery can be charged through the power charging interface. When the mobile phone is in the working state, the battery provides electric energy for it. In the charging state, the washing phone does not work.

Then it receives the first signal continuously sent by the first trigger part 310 in a continuously triggered state, and receives the second signal sent by the second trigger part 320 being triggered instantaneously, and records the current sent by the distance sensor 400 The distance value is used as the starting distance of the pump, specifically: in the charging state, the power charging interface continuously sends the first signal to the controller 600; at this time, if the touch button is pressed, the touch button instantly sends the second signal to the controller 600, then The controller 600 records the distance value sent by the distance sensor 400 as the pump starting distance.

It should be noted that in the non-charging state, even if the touch button is pressed, it will not enter the setting state of the pump starting distance. This can prevent people from accidentally touching the touch button and setting the pump starting distance by mistake.

5, further, the containing portion 110 is a tank body, the tank body is provided with an insertion port 111; the pump 500 is provided with a first delivery tube 510, the first delivery tube 510 passes through the insertion port 111 is inserted into the tank body and extends to the bottom of the tank body.

Further, the first delivery pipe 510 is tightly fitted with the insertion port 111; the tank body is provided with a vent hole 112. The vent hole 112 connects the inside and outside of the tank body, and maintains a constant pressure inside and outside the tank body.

5 and 6, further, the vent hole 112 is interference-connected with an anti-leakage piece 113, the anti-leakage piece 113 is provided with an air passage, and one end of the air passage facing the tank has a flat The long and narrow first mouth end 114, the first mouth end 114 is rectangular, and the first mouth end 114 is inserted into the tank body. The end of the air passage away from the tank body has a second mouth end, the second mouth end is located outside the tank body, and the second mouth end has a larger cross-section than the first mouth end 114. Because the first mouth end 114 is long and narrow, even if the washing phone is turned sideways, the liquid in the tank is difficult to pour out from the first mouth end 114. The leak-proof member 113 can not only realize the constant flow inside and outside the tank. It can also achieve leak-proof function.

2, 3 and 4, further, the nozzle 210 includes a nozzle body 213, a first spray member 211 and a second spray member 212, the nozzle body 213 is provided with a nozzle channel 214 and a nozzle 215, so The mouth 215 is in communication with the nozzle channel 214, the first spray member 211 and the second spray member 212 are located in the mouth 215; the liquid passes through the first spray member 211 and the second spray member 212 When it rotates in the second spray member 212, it sprays from the atomizing nozzle hole 223 of the second spray member 212.

3 and 4, further, the second spray member 212 is provided with a cavity, the first spray member 211 is inserted into the cavity of the second spray member 212, and the first spray member 211 and A plurality of first spray channels are formed between the inner walls of the cavity of the second spray member 212, and the cone-shaped atomization nozzle hole 223 is provided at the center of the bottom surface of the cavity, and the atomization nozzle hole 223 is formed from the atomization nozzle hole 223. 223 extends around a plurality of second spray channels 222, the plurality of second spray channels 222 are in one-to-one correspondence with the plurality of first spray channels, and the first spray member 211 is far away from the second spray member One end of 212 is provided with a protruding piece 221 extending outward, and there are two protruding pieces 221, which are respectively located on two sides.

After the liquid passes through the nozzle channel 214, it enters the space formed between the first spray member 211 and the nozzle 215 from the gap, and then enters the first spray channel. Since the first spray channel is smaller than the space between the first spray member 211 and the nozzle 215, the hydraulic pressure increases and the liquid accelerates. The liquid then enters the second spray channel 222 from the first spray channel. Since the multiple second spray channels 222 intersect the atomizing nozzle hole 223 and the atomizing nozzle hole 223 to form a spiral pinwheel shape, the liquid rotates at the bottom of the cavity of the second spray member 212 and then gathers in the atomizing nozzle hole 223, Spray and atomize.

Specifically, the distance sensor 400 is an infrared sensor.

In addition, the self-adjusting induction height sensor is provided with a housing 700 which is threadedly connected to the upper part of the accommodating part 110.
