Referring to fig. 1-3, an embodiment of the present invention provides a cleaning apparatus, which includes a frame, a cleaning module, and a pressing mechanism 200, wherein the pressing mechanism 200 includes a pushing member 210 and a first elastic member 220, one end of the pushing member 210 is mounted on the frame, the length of the pushing member 210 is adjustable, the pressing mechanism 200 has an elastic pressing state, when the pressing mechanism 200 is in the elastic pressing state, the other end of the pushing member 210 is connected with a first end of the first elastic member 220, a second end of the first elastic member 220 is connected with the cleaning module, and the pushing member 210 is used for pushing the first elastic member 220 and pressing the cleaning module through the first elastic member 220.
In this embodiment, by providing the pressurizing mechanism 200, the pressurizing mechanism 200 pushes the cleaning module through the length change of the pushing member 210, so as to increase the friction between the cleaning module and the ground, thereby making the cleaning effect better. Meanwhile, since the pressurizing mechanism 200 has an elastic pressurizing state, when the pressurizing mechanism 200 is in the elastic pressurizing state, the pushing member 210 pressurizes the cleaning module through the first elastic member 220, and the cleaning module can be self-adapted to the floating of the ground due to the elastic action of the first elastic member 220 itself.
Specifically, the pushing member 210 may be an electric push rod 240 or a pneumatic push rod 240.
In some embodiments, the pressing mechanism 200 further includes a pressing member 230, the second end of the first elastic member 220 is connected to the cleaning module through the pressing member 230, the pressing mechanism 200 further has a rigid pressing state, and when the length of the pushing member 210 is adjusted such that the other end of the pushing member 210 abuts against the pressing member 230, the pressing mechanism 200 is switched to the rigid pressing state, and at this time, the pushing member 210 is used to directly press the cleaning module.
In the present embodiment, by providing the pressing member 230, the second end of the first elastic member 220 is connected to the cleaning module through the pressing member 230. When the pressing mechanism 200 is in the elastic pressing state, the length adjustable end of the pushing member 210 pushes the first elastic member 220, and the first elastic member 220 acts on the cleaning module through the pressing member 230, so that the cleaning module adapts to the floating of the ground. When the pressurizing mechanism 200 is in the rigid pressurizing state, the length adjustable end of the pushing member 210 is extended to directly contact with the pressurizing member 230, so that the cleaning module is in rigid contact with the ground for pressurizing, and the elastic force of the first elastic member 220 cannot play a role, so that the cleaning mechanism is applicable to some floors with high cleaning difficulty and need repeated scrubbing.
Further, the pressing member 230 has a connecting portion 232, the pressing member 230 is provided with a limiting groove 231 along a first direction along a length direction, the connecting portion 232 is located at one side of the limiting groove 231 away from the cleaning module, the first direction is a length direction of the pushing member 210, the pressing mechanism 200 includes a push rod 240, the push rod 240 passes through the limiting groove 231 to connect a first end of the first elastic member 220 with another end of the pushing member 210, and a second end of the first elastic member 220 is connected with the connecting portion 232.

When the pressurizing mechanism 200 is in the rigid pressurizing state, the pushing member 210 pushes the pushing rod 240 to move to the lowest end of the limiting groove 231, that is, the pushing rod 240 abuts against the inner wall of the lowest end of the limiting groove 231, that is, the pushing member 210 directly abuts against the pressurizing member 230 through the pushing rod 240, and when the length adjustable end of the pushing member 210 continues to extend, the pushing member 210 can directly push the pressurizing member 230 to further push the cleaning module, so that the friction force between the cleaning module and the ground is increased, and the cleaning mechanism is used for cleaning the ground with great difficulty.
