Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning, and in particular relates to a cleaning structure and a window cleaning machine. Background Art

[0002] A window cleaning robot is a new type of smart home appliance, also known as an automatic window cleaning machine, a glass cleaning robot or an intelligent window cleaning device. It has a vacuum pump or fan device at the bottom, which can adhere tightly to the glass surface through a strong adsorption effect. The window cleaning robot can not only automatically detect the corner distance of the window, but also intelligently plan the best window cleaning path to achieve fully automatic window cleaning.

[0003] Typically, the cleaning cloth of the window cleaning robot is attached to its bottom so as to clean a plane parallel to the bottom surface of the robot. In order to improve the cleaning effect, sealing foam is usually used to increase the elastic support of the cleaning cloth so that the cleaning cloth can better fit the surface of the curtain wall.

[0004] However, the main function of the sealing foam is to prevent air leakage, and its elastic force is not enough to support the cleaning cloth against the curtain wall. In particular, the sealing foam is prone to elastic fatigue after repeated use. When a thinner cleaning cloth is used to wipe the window, the resilience of the sealing foam is not enough to support the cleaning cloth against the curtain wall, resulting in unsatisfactory window cleaning effect.

[0030] See also Figures 1 to 3 The embodiment of the present application provides a cleaning structure and a window cleaning machine 200 having the same. The window cleaning machine 200 can effectively clean the curtain wall of a building, and is particularly suitable for glass curtain walls. Glass curtain walls are generally composed of large glass panels, aluminum or steel structural frames, and sealing materials. It is understandable that the window cleaning machine 200 can be used in various environments and situations in addition to cleaning glass curtain walls. The specific application objects can be selected according to needs, and are not limited here.

[0031] See also Figures 1 to 3The cleaning structure includes: an elastic component 30, a main body shell 10, and a cleaning plate group 20 arranged relative to the main body shell 10. It is understandable that the main body shell 10 can be adsorbed on the curtain wall by vacuum adsorption, and walk on the curtain wall through its own running structure 40. The cleaning plate group 20 is located between the glass curtain wall and the main body shell 10. The main body shell 10 cleans the glass curtain wall through the cleaning plate group 20 during the walking process. The elastic component 30 includes a guide anti-slip part 32 and an elastic part 31 with elastic restoring force. It is understandable that when the elastic part 31 is compressed and deformed, it can apply a pushing force to the outside through a reaction force. The elastic member 31 is connected to the surface of the main housing 10 facing the cleaning plate group 20, and the guide anti-slip member 32 is located on the plate surface of the cleaning plate group 20 facing the main housing 10. The main housing 10 is provided with a guide accommodating hole 121. The guide anti-slip member 32 is slidably inserted into the guide accommodating hole 121 to guide the cleaning plate group 20 to slide toward or away from the main housing 10. When the cleaning plate group 20 slides toward the main housing 10, the guide anti-slip member 32 compresses the elastic member 31; wherein, a plurality of elastic components 30 are arranged, and each of the elastic components 30 is arranged at circumferential intervals around the cleaning plate group 20.

[0032] See also Figures 1 to 3 It can also be understood that when the cleaning plate group 20 slides relative to the main body shell 10, the guide anti-slipping member 32 cooperates with the guide accommodating hole 121 to guide the relative sliding of the cleaning plate group 20 and the main body shell 10, and the sliding direction is perpendicular to the glass curtain wall. In. The multiple elastic members 31 arranged at intervals all push the cleaning plate group 20 toward the glass curtain wall through the reaction force, so that the cleaning plate group 20 elastically clings to the glass curtain wall, so that the cleaning plate group 20 adaptively fits the glass curtain wall, that is, the cleaning plate group 20 is always in close contact with the glass curtain wall during the movement of the main body shell 10, thereby improving the cleaning efficiency of the glass curtain wall, and the cooperation of the multiple guide accommodating holes 121 and the guide anti-slipping members 32 can guide the cleaning plate group 20 to slide smoothly, avoid the cleaning plate group 20 from shaking in the direction parallel to the glass curtain wall, thereby improving the cleaning effect of the glass curtain wall.

[0037] Strong corrosion resistance: Stainless steel has good corrosion resistance and can remain stable under harsh conditions such as humid, dusty, and chemical environments. It is not easy to rust, so it is suitable for use in outdoor environments and clean occasions that come into contact with water and chemicals.

[0038] High Strength: Stainless steel tube springs have high fatigue resistance and can withstand repeated external forces and pressures without deformation or mechanical fatigue.

[0039] Long life: Due to the corrosion resistance and high strength of stainless steel, tube springs made of stainless steel usually have a long service life, can maintain stable performance in long-term use, and reduce replacement and maintenance costs.

[0040] Optionally, the tube spring can be sleeved on the guide anti-slip component 32, with one end of the tube spring abutting against the main body housing 10, and the other end of the tube spring abutting against the cleaning plate assembly 20, so that when the guide anti-slip component 32 is slidably inserted into the guide accommodating hole 121, the tube spring can undergo compression deformation.

The shape of the hole wall of the guide accommodating hole 121 is adapted to the side surface of the corresponding position on the guide rod 321, so that the guide rod 321 cooperates with the guide accommodating hole 121 to guide the cleaning plate group 20 to slide back and forth, and the side surface shape of the elastic buckle foot 323 can also be adapted to the shape of the hole wall of the guide accommodating hole 121, which is not limited here and can be selected according to actual conditions.

[0047] See also Figures 4 to 6 It can be understood that the elastic buckle foot 323 has a certain elasticity and can be tilted toward the center of the guide accommodating hole 121, so as to facilitate the buckle anti-detachment portion 322 on the elastic buckle foot 323 to bypass the limiting portion 123 and enter the guide accommodating hole 121. The material of the elastic buckle foot 323 and the guide rod 321 can be plastic, so that a certain elastic deformation can occur.
