[0038] Reference Figure 1 and Figure 2 , an embodiment of the present invention provides a hand-washing machine capable of automatically adjusting the sensing height, comprising:

[0039] A containing portion 110, wherein the containing portion 110 is used to contain a liquid, and the liquid may be a disinfectant or a hand soap, etc.;

[0040] Nozzle 210;

[0041] A pump 500, the pump 500 is used to pump the liquid in the container 110 to the nozzle 210;

[0042] A controller 600, wherein the controller 600 is connected to the pump 500;

[0043] A distance sensor 400, which is connected to the controller 600;

[0044] A partially exposed first triggering unit 310, wherein the first triggering unit 310 is connected to the controller 600;

[0045] A partially exposed second triggering unit 320, wherein the second triggering unit 320 is connected to the controller 600;

[0046] Wherein, the controller 600 is configured as follows:

[0047] Receiving a first signal continuously sent by the first triggering unit 310 in a continuously triggered state, and receiving a second signal sent by the second triggering unit 320 being instantaneously triggered, and recording the distance value currently sent by the distance sensor 400 as the pump starting distance;

[0048] The distance value received from the distance sensor 400 is equal to the pump start distance, and a working signal is sent to the pump 500.

[0049] In this embodiment, non-contact triggering is achieved through the distance sensor 400. The triggering structure is composed of circuit electronic components. Compared with the press-type mechanical structure, it can achieve a simpler structure and is more conducive to the miniaturization of the hand washer. The non-contact triggering can better reduce the risk of cross-infection of bacteria and viruses. It has intelligent characteristics and is more convenient to use. Different pump starting distances can be set to achieve different sensing heights to trigger the hand washer to spray liquid, so that the hand washer can meet the height requirements of different scenarios.

[0050] Further, the first trigger unit 310 is a power charging interface; specifically, the first trigger unit 310 is a USB interface.

[0051] Furthermore, the hand washer with automatic adjustment of sensing height also includes a battery and a power connection circuit, and the power charging interface is connected to the battery through the power connection circuit.

[0052] Furthermore, the second triggering unit 320 is a touch button.

[0053] It should be noted that the battery can be charged through the power charging interface, and the battery provides power energy for the hand washer when the hand washer is in working state. In the charging state, the hand washer does not work.

[0054] Then, the first signal continuously sent by the first trigger unit 310 in a continuously triggered state is received, and the second signal sent by the second trigger unit 320 when instantaneously triggered is received, and the distance value currently sent by the distance sensor 400 is recorded as the pump starting distance. Specifically, in the charging state, the power charging interface continuously sends a first signal to the controller 600; at this time, if the touch button is pressed, the touch button instantaneously sends a second signal to the controller 600, and the controller 600 records the distance value currently sent by the distance sensor 400 as the pump starting distance.

[0055] The distance value received from the distance sensor 400 is equal to the pump starting distance, and a working signal is sent to the pump 500. Specifically, in the non-charging state, the controller 600 is powered by the battery and does not receive the first signal at this time; if the controller 600 receives the distance value sent by the distance sensor 400 and the distance value is equal to the recorded pump starting distance, the controller 600 sends a working signal to the pump 500; the pump 500 works to pump the liquid in the container 110 to the nozzle 210, and the nozzle 210 sprays and atomizes the liquid.

[0056] It should be noted that in the non-charging state, even if the touch button is pressed, the pump start distance setting state will not be entered. This can prevent people from accidentally touching the touch button and setting the pump start distance incorrectly.

[0057] Reference Figure 5 Further, the accommodating portion 110 is a tank body, and the tank body is provided with an insertion port 111; the pump 500 is provided with a first delivery pipe 510, and the first delivery pipe 510 passes through the insertion port 111 and is inserted into the tank body and extends to the bottom of the tank body.

[0058] Furthermore, the first delivery pipe 510 is tightly matched with the insertion port 111, and the tank body is provided with a vent hole 112. The vent hole 112 connects the inside and outside of the tank body to maintain a constant pressure inside and outside the tank body.

[0059] Reference Figure 5 and Figure 6 Furthermore, a liquid-leakage-proof part 113 is interference-connected in the vent hole 112, and the liquid-leakage-proof part 113 is provided with an air passage, and the air passage has a first elongated and narrow end 114 at one end facing the tank body, and the first end 114 is rectangular and inserted into the tank body. The air passage has a second end at one end away from the tank body, and the second end is located outside the tank body, and the second end has a larger cross-section than the first end 114. Since the first end 114 is elongated and narrow, even if the hand washer turns over, it is difficult for the liquid in the tank body to pour out from the first end 114. The liquid-leakage-proof part 113 can not only achieve a constant pressure inside and outside the tank body, but also achieve a leak-proof function.

[0060] Reference Figure 2 , Figure 3 and Figure 4 Furthermore, the nozzle 210 includes a nozzle body 213, a first spray element 211 and a second spray element 212. A nozzle channel 214 and a mouth 215 are provided in the nozzle body 213. The mouth 215 is connected to the nozzle channel 214. The first spray element 211 and the second spray element 212 are located in the mouth 215. When the liquid passes through the first spray element 211 and the second spray element 212, it rotates in the second spray element 212 and then is sprayed out from the atomizing spray hole 223 of the second spray element 212.

[0061] Reference Figure 3 and Figure 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 a plurality of first spray channels are formed between the inner walls of the cavities of the first spray member 211 and the second spray member 212, a conical atomizing hole 223 is provided at the center of the bottom surface of the cavity, a plurality of second spray channels 222 extend from the atomizing hole 223 to the surrounding areas, the plurality of second spray channels 222 are connected with the plurality of first spray channels in a one-to-one correspondence, and a convex member 221 extending outward is provided at one end of the first spray member 211 away from the second spray member 212, and there are two convex members 221, which are respectively located on both sides.

[0062] Specifically, the main body of the first spray member 211 is cylindrical, and the radius of the main body of the first spray member 211 is smaller than the radius of the nozzle channel 214 near the outlet of the first spray member 211, so a gap for liquid to pass through is formed between the first spray member 211 and the nozzle channel 214. 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 is accelerated. Then the liquid enters the second spray channel 222 from the first spray channel. Since the plurality of second spray channels 222 intersect at the atomizing spray hole 223 and form a spiral windmill shape with the atomizing spray hole 223, the liquid rotates at the bottom of the cavity of the second spray member 212, and then gathers at the atomizing spray hole 223, sprays out and atomizes.

[0063] Specifically, the distance sensor 400 is an infrared sensor.

[0064] In addition, the automatic adjustment inductive height sensor is provided with a housing 700, and the housing 700 is threadedly connected to the top of the accommodating portion 110. The nozzle 210, the pump 500, the battery and the controller 600 are located in the housing 700. The atomizing nozzle 223 of the nozzle 210 leaks out and faces downward. The distance sensor 400 is located on one side of the nozzle 210, and the direction of emitting infrared rays is downward. The touch button is located on the upper surface of the housing 700. The power charging interface is located on the side of the housing 700, and the power charging interface can be plugged with waterproof glue to prevent water from entering.

[0065] The above is only a preferred embodiment of the present invention. The present invention is not limited to the above implementation mode. As long as the technical effect of the present invention is achieved by the same means, it should belong to the protection scope of the present invention.
