Description

Technical Field

[0001] This utility model belongs to the technical field of window cleaning equipment, and in particular relates to a base station adsorption mechanism for a window cleaning device. Background Technology

[0002] Window cleaning systems used for cleaning windows in high-rise buildings typically consist of a base station and a cleaning assembly. The base station is placed on the ground and connected to the cleaning assembly via a safety rope to prevent the assembly from accidentally falling and posing a risk of damage. The base station is typically connected to the ground using its own weight, bolts, or vacuum suction. The first two methods have been phased out due to insufficient reliability or cumbersome operation. Vacuum suction is currently the mainstream fixing method.

[0003] Chinese utility model patent CN222622843 discloses a vacuum adsorption structure and a base station device, including a suction cup assembly and a vacuum generating assembly. The vacuum generating assembly includes an air pump and a vent valve connected to the air pump. The air pump removes air between the suction cup and the ground, causing the base station to adhere to the ground. When the base station leaves the ground, the vent valve is opened to engage in vacuum adsorption. Although this patent has a relatively reliable adsorption structure, the air pump makes the structure complex. Venting requires simultaneously pulling the edge of the suction cup and lifting the base station, which is inconvenient. Furthermore, the mechanical structure of the vent valve contributes to the overall complexity, high manufacturing cost, high failure rate, high power consumption, and numerous inconveniences in practical use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a window cleaning device that eliminates the vacuum pump component and relies on a flexible tube to enhance adsorption. It has a simple structure, low power consumption, and low failure rate.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a window cleaning device, including a base station and a window cleaning component, wherein the base station and the window cleaning component are connected by a safety rope, the base station has a vacuum adsorption mechanism, the vacuum adsorption mechanism includes a suction cup and a flexible tube, and the flexible tube communicates with the cavity inside the suction cup.

[0006] The hose is made of silicone, rubber, or PU. The diameter of the hose is no greater than 50mm. The length of the hose is 5mm-600mm.

[0007] The beneficial effects achieved by this utility model are as follows: This novel window cleaning device, by setting up a flexible hose connecting the cavity of the suction cup to the environment, ensures reliable adsorption when the base station moves due to the inertial force of the window cleaning component detaching, causing the cavity inside the suction cup to suddenly expand. This is achieved by closing the hose due to the pressure difference between the inside and outside, thus ensuring a reliable adsorption effect and eliminating the risk of the window cleaning component falling from a height. When it is necessary to move the base station, it can be done simply by moving the base station slowly. The entire device's base station vacuum adsorption mechanism has a simple structure, consumes no additional power, and significantly reduces the failure rate. Attached Figure Description

[0014] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0015] To further and thoroughly understand the contents of this utility model, detailed steps will be set forth in the following description to illustrate the utility model. Obviously, the implementation of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, it should be understood that this utility model can be implemented in different forms and should not be construed as limited to the embodiments set forth herein. When the terms "comprising" and / or "including" are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0016] See Figures 1-3 One embodiment of the window cleaning device of this utility model includes a base station 1 and a window cleaning component 2, which are connected by a safety rope 3. When the window cleaning component 2 accidentally falls off, the safety rope 3 connected to the base station can prevent the window cleaning component from falling.

[0017] In this embodiment, the base station has a vacuum adsorption assembly, which includes a suction cup 4 and a flexible tube 5. The suction cup 4 is similar to those in the prior art and is made of a flexible material. In its free state, the suction cup 4 is roughly disc-shaped with a cavity. One end of the flexible tube communicates with the cavity of the suction cup, and the other end communicates with the environment. In the working state, the base station expels the air from the suction cup under its own weight, and the suction cup can be placed on the ground, at which point it has no adsorption effect. When it is necessary to move the base station, it can be moved by slowly lifting it.

[0018] To achieve reliable operation, the hose is made of silicone, rubber, PU, ​​etc., with a diameter not exceeding 50mm and a length extending 5mm-600mm beyond the suction cup. In certain situations, if the window cleaning assembly detaches due to an accident, the safety rope, under inertial force, will cause a slight movement of the base station, causing the suction cup to momentarily detach from the ground. The cavity area within the suction cup suddenly increases, and under the pressure difference between the inside and outside of the cavity, one end of the hose is instantly sucked shut, passively and firmly adhering the base station to the ground, preventing the window cleaning assembly from falling. Figure 4 , Figure 5 As shown, hoses of different lengths create different closure effects. When it is necessary to release the adsorption, the base station can be slowly moved to detach from the adsorption.

[0019] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
