The detection unit 200 for detecting the level of the cleaning consumables is assembled in the positioning portion, and the inductive switch (not shown) is disposed in the assembly chamber 400 and matched with the detection unit 200.
The inductive switch of the present invention is a hall switch, which is magnetically connected to the detection unit 200. The inductive switch of the present invention may also be an electromagnetic inductive switch, a photoelectric inductive switch, a microwave inductive switch, etc., and when the inductive switch is switched, the detection unit 200 is a detection unit 200 capable of generating an induction with the switches. The inductive switch of the embodiment is a Hall switch which is a conventional inductive switch easy to obtain, and the production cost can be reduced.
It should be noted that the assembly chamber 400 of the present invention is not communicated with the accommodating chamber 110, and the inductive switch is assembled in the assembly chamber 400, so that the inductive switch does not contact with the cleaning consumables of the accommodating chamber 110. The novel matching of this implementation means that when the detection unit 200 reaches and corresponds to the displacement of the inductive switch, the detection unit 200 generates a magnetic field to the inductive switch, thereby triggering the inductive switch to be turned on or turned off. The magnetic connection between the hall switch and the detection unit 200 means that the magnetic field generated by the detection unit 200 can trigger the connection relationship between the induction switch and the induction switch.
Utility model's automation is put in device and is used like this: the user adds the cleaning consumables to the inside of the accommodating chamber 110. Because the positioning part 300 is communicated with the accommodating chamber 110, the liquid level heights of the positioning part 300 and the cleaning consumables of the accommodating chamber 110 are the same, the detection unit 200 moves along with the liquid level height of the cleaning consumables, when the cleaning consumables in the accommodating chamber 110 are less than the alarm liquid level, the detection unit 200 moves to the horizontal height corresponding to the position of the induction switch, the detection unit 200 generates a magnetic field to the induction switch, the induction switch is triggered to be turned on or turned off, and therefore the induction switch sends out a warning signal and prompts a user.

It should be noted that the sensing end and the routing of the sensing switch of the utility model are completely assembled inside the assembly cavity 400, the cleaning consumable feeding device is simple, and the fixing buckle 430 is used for buckling the sensing end after the sensing end of the sensing switch is embedded in the assembly cavity 400, so as to prevent the sensing end of the sensing switch from being separated, thereby ensuring the reliability of the liquid level detection structure. According to the utility model, the inductive switch and the cleaning consumables can be completely isolated through the assembly cavity 400, the cleaning consumables are prevented from leaking and damaging the inductive switch, and meanwhile, the inductive switch is ensured to be magnetically connected with the detection unit 200, so that the use reliability is improved.
It should be noted that the position correspondence in the present invention refers to a position where the magnetic field generated by the detection unit 200 can trigger the on or off of the inductive switch when the detection unit 200 moves to the position of the inductive switch along with the detection of the liquid level of the cleaning consumables, which is called position correspondence.
Because the tongue tube only is provided with live wire and zero line two routes, the tongue tube is the glass structure and needs all to soak in the washing consumptive material moreover, washs the inside of consumptive material infiltration tongue tube easily and damages the inner structure of tongue tube. Hall switch is provided with live wire, zero line and three routes of ground wire, and Hall switch establishes and washs the consumptive material and be isolated completely moreover, washs the consumptive material and can not damage Hall switch and establish the structure. The experimental result proves that compared with the reed switch in the prior art, the Hall switch has high reliability and long service life.
