Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

Please refer to the attached drawings. It should be understood that the structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any structure modification, ratio relationship change or size adjustment should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the function that the present invention can produce and the purpose that the present invention can achieve.

As shown in fig. 1-2, the utility model provides a desk-top towards tooth ware of anhydrous shut-down formula, including main fuselage 1, be equipped with water tank 2 and motor 3 on the main fuselage 1, splendid attire washing liquid 4 in the water tank 2 is equipped with floater 5 in the water tank 2, and floater 5 includes the magnetic part, still is equipped with proximity switch 6 on the main fuselage 1, and proximity switch 6 is connected with motor 3.

The utility model discloses in the use, floater 5 can be along with the liquid level decline of washing liquid 4, and when washing liquid 4 used up, floater 5 can descend to the bottom of water tank 2, and the magnetic part changes proximity switch 6's magnetic flux for proximity switch 6 operating condition changes, thereby realizes under the condition of no washing liquid 4, automatic shutdown motor 3. Adopt the utility model discloses can avoid motor 3 to take place the idle running under the condition of no washing liquid 4, promote the life of whole system, reduce the potential safety hazard that brings because of the 3 temperature risees of motor.

As a preferred embodiment, the proximity switch 6 in the present embodiment includes a reed switch and a hall switch. As shown in fig. 2, when the float ball 5 descends along with the liquid level of the cleaning liquid 4, the magnetic member will approach the reed switch, the magnetic field applied to the reed switch changes, and when the float ball 5 descends to the bottom of the water tank 2, the reed switch is disconnected under the action of the magnetic field, so that the motor 3 is shut down. The working process when the Hall switch is adopted is similar, and the description is omitted.

As a preferred embodiment, as shown in fig. 1, the magnetic member in this embodiment includes a ring magnet 510, and the floating ball 5 further includes a foaming layer 520 or a plastic layer coated on the ring magnet 510. The ring magnet 510 may provide a stable magnetic field, and the density of the foam layer 520 or the plastic layer is less than that of the cleaning solution 4, so that the ring magnet 510 can float on the surface of the cleaning solution 4 and descend along with the surface of the cleaning solution 4.
