Example 1

Referring to fig. 1 to 4, the present embodiment provides a cleaning mechanism applied to a cleaning apparatus, including a cleaning head assembly 3 and an electromagnetic assembly 5.

The cleaning device comprises a machine body 1, a cleaning mechanism is suitable for being arranged on the machine body 1, and the cleaning device is used for mopping and sweeping the cleaning surface through the cleaning mechanism. Wherein the cleaning surface is generally referred to as the floor. In a specific implementation scenario, the cleaning device may be a cleaning robot, such as a floor mopping robot, or a conventional floor mopping machine, such as a handheld floor mopping machine, a hand-push floor mopping machine, or may be a riding floor mopping machine, which is not limited herein.

Referring to fig. 1 and 2, in the present embodiment, the cleaning device is a cleaning robot, and is capable of autonomously performing a cleaning task on the ground of the working area. For convenience of explanation, the cleaning robot in this embodiment is defined as "up" in the upper part and "down" in the lower part of the cleaning robot shown in fig. 2, and the cleaning mechanism is provided below the main body 1, with reference to the case where the cleaning robot performs cleaning on a horizontal floor surface. The above directional definitions are for illustrative purposes only and are not to be construed as limiting the present application. In this embodiment, the number of the cleaning mechanisms is two, and the two cleaning mechanisms are arranged side by side, but the number of the cleaning mechanisms may be 1 or 3 or more.

Wherein, the electromagnetic component 5 is suitable for being arranged on the body 1 of the cleaning device, and the electromagnetic component 5 can generate an electromagnetic field when being connected with a power supply. Specifically, the electromagnetic assembly 5 comprises an electromagnet and a conductive coil wound on the electromagnet, the conductive coil is connected with a power supply of the cleaning equipment, and when the conductive coil is connected with the power supply, an electromagnetic field is generated around the electromagnet, so that the magnetic material can be adsorbed. More specifically, the electromagnetic assembly 5 is connected to a power source of the cleaning device and is powered by the own power source of the cleaning device.

The cleaning head assembly 3 is used for mopping the ground and comprises cleaning cloth discs (31, 32) and a connecting structure for connecting the cleaning cloth discs (31, 32) with the body 1 of the cleaning device in a vertically floating manner. In a specific implementation scene, the cleaning cloth discs (31, 32) are connected with cleaning cloth which is used for cleaning the ground, and through the connecting structure, the cleaning cloth discs (31, 32) and the cleaning cloth can move in the up-and-down direction together, so that the cleaning cloth and the cleaning cloth discs (31, 32) can be located at a lifting position which is higher than the ground or a cleaning position which is contacted with the ground. In particular, the attachment structure comprises a biasing member 35 for pushing down on the wipe disc (31, 32) so as to urge the wipe disc (31, 32) so that it has a tendency to move towards the wiping position.

Based on the technical scheme, the cleaning mechanism controls the generation and the extinction of the electromagnetic field by switching on and off the electromagnetic assembly 5, so that the magnetic attraction is generated on the magnetic attraction component 33 to realize the lifting of the cleaning cloth discs (31, 32), when the electromagnetic assembly 5 is powered off, the electromagnetic field disappears, and the cleaning cloth discs are downwards abutted and pushed to the wiping position through the biasing component 35, so that the lifting control of the cleaning cloth discs is realized. The electromagnetic assembly is adopted to control the lifting of the cleaning cloth disc in an electromagnetic attraction mode, the cleaning cloth disc can be lifted or lowered according to actual requirements, and the control is more flexible.
