[0037] See also Figures 1 to 5 The embodiment of the present application provides a window cleaning base station 100, which can cooperate with a window cleaning machine 130 to clean the glass curtain wall of a building.

[0038] See also Figures 1 to 3 The window cleaning base station 100 includes: a base station housing 110 , a power cord and a suction cup assembly 200 .

[0039] See also Figure 1 The base station housing 110 is provided with a receiving cavity 101; when the base station housing 110 is vertically arranged, the receiving cavity 101 is opened on the side surface of the base station housing 110, and the base station housing 110 also has a receiving cavity, and the receiving cavity can be used for arranging other structural parts and electronic components.

[0040] The two ends of the power cord are respectively connected to the window cleaning machine 130 and the base station housing 110. The power cord is made of flexible material and can transmit the electrical energy of the power supply in the base station housing 110 to the window cleaning machine 130. The flexibility of the power cord enables the power cord to be wound, and when necessary, the power supply can be unfolded to adapt to the cleaning operation of the window cleaning machine 130.

[0041] See also Figures 1 to 3 , the window cleaning machine 130 can be accommodated in the accommodation cavity 101 and the power cord is collected in the base station housing 110, at this time, the base station housing 110 can be lifted up and the window cleaning machine 130 can be taken away together. Or the window cleaning machine 130 is taken out of the accommodation cavity 101 and the power cord is released from the base station housing 110 to cooperate with the window cleaning operation of the window cleaning machine 130.

[0042] The suction cup assembly 200 is connected to the base station housing 110. It can be understood that the suction cup assembly 200 can produce a vacuum adsorption effect, thereby being adsorbed onto a corresponding structural member, and at the same time, the vacuum adsorption effect is contacted by passing air, which is convenient to use.

[0043] See also Figures 1 to 3 It can be understood that when the base station housing 110 is located on the support, the suction cup assembly 200 can vacuum absorb the support. The support can be the floor of a building, and the floor has a certain degree of flatness. When the base station housing 110 is set on the floor, the suction cup assembly 200 is adsorbed on the floor through the vacuum adsorption effect, thereby strengthening the connection between the base station housing 110 and the floor, and improving the stability of the window cleaning base station 100. After the window cleaning machine 130 completes the operation, air is introduced between the suction cup assembly 200 and the floor, thereby releasing the vacuum adsorption effect, so that the base station housing 110 can be easily lifted, and the convenience of using the window cleaning base station 100 is improved.

[0044] See also Figures 2 to 4 In some embodiments, two suction cup assemblies 200 are arranged at intervals, and both of the two suction cup assemblies 200 are connected to the bottom surface of the base station housing 110 .

[0045] See also Figures 2 to 4 Optionally, the setting of the double suction cup assembly 200 can prevent the window cleaning machine 130 from falling off during use. After the window cleaning machine 130 is connected to the window cleaning base station 100, unexpected situations may occur during operation, especially potential risks of falling. In order to ensure the safety of personnel, two suction cup assemblies 200 are set on the window cleaning base station 100. The two suction cup assemblies 200 can firmly fix the base station housing 110 on the ground, thereby effectively preventing the window cleaning machine 130 from accidentally falling.

[0046] See also Figures 2 to 4 In some embodiments, the suction cup assembly 200 includes a suction cup 201 disposed at the bottom of the base station housing 110 and a vacuum generator 202 located in the base station housing 110. When the suction cup 201 abuts against the ground, the vacuum generator 202 extracts the air between the suction cup 201 and the ground so that the suction cup 201 is vacuum-adsorbed to the ground.

[0047] The suction cup 201 is in the shape of an inverted bowl, and negative pressure is generated between the suction cup 201 and the ground, thereby forming a strong adsorption force between the base station housing 110 and the ground, ensuring that the window cleaning base station 100 is firmly fixed on the ground during operation.

[0048] When the window cleaning machine 130 encounters an emergency during operation, such as unexpected loss of control or failure, the window cleaning base station 100 can still remain firmly on the ground to prevent the window cleaning machine 130 robot from falling, thereby minimizing the potential risk of personal injury.

[0049] See also Figures 2 to 4 Optionally, when it is necessary to lift the window cleaning base station 100 from the ground, the vacuum generator 202 connects the suction cup 201 and the external space so that external air can enter between the suction cup 201 and the ground, thereby releasing the vacuum adsorption effect. At this time, the base station housing 110 can be easily lifted, and the operation process is simple and convenient.

[0050] In some embodiments, the suction cup assembly 200 also includes a suction cup bracket 203, the suction cup 201 is made of a flexible material and is connected to the suction cup bracket 203, and the suction cup bracket 203 is connected to the base station housing 110. It can be understood that the suction cup bracket 203 can be detachably connected to the base station housing 110 by screws.

[0051] See also Figures 2 to 4 Optionally, the material of the suction cup 201 can be a silicone material. The suction cup 201 made of silicone material can generate a vacuum adsorption force on a smooth surface to achieve the purpose of fixing or adsorption, and has the following characteristics:

[0052] High adsorption force: The suction cup 201 made of silicone material has good adsorption performance and can generate strong vacuum adsorption force when it contacts the surface, ensuring that the adsorbent is firmly fixed on the surface.

[0053] Soft and Elastic: Silicone material has a certain softness and elasticity, which can form a seal when it contacts the surface, thereby increasing the adsorption effect and adapting to surfaces of different shapes and curvatures.

[0054] High and low temperature resistance: Silica gel material has good high and low temperature resistance, and can maintain stable adsorption performance in a wide temperature range.

[0055] See also Figures 2 to 4 In some embodiments, the suction cup 201 includes an adsorption portion 2011 and a covering portion 2012 connected to the adsorption portion 2011 , and the covering portion 2012 covers and connects to the suction cup bracket 203 .

[0056] Optionally, the adsorption portion 2011 is used to fit the ground and generate a vacuum adsorption force between the ground and the covering portion 2012 is used to connect to the suction cup bracket 203 to improve the reliability of the connection between the adsorption portion 2011 and the suction cup bracket 203.

[0057] See also Figures 2 to 4In some embodiments, the suction cup bracket 203 includes a disc body 2031 and a connecting column 2032 connected to the disc body 2031, the disc body 2031 is wrapped in the suction cup 201, and the two ends of the connecting column 2032 are respectively connected to the disc body 2031 and the base station shell 110.

[0058] Optionally, the disc body 2031 may be made of hardware material or hard plastic, thereby improving the structural strength of the suction cup 201 .

[0059] Optionally, the covering portion 2012 and the disk body 2031 are connected together by a beer-insertion process, and a threaded hole is provided on the connecting column 2032, so that the disk body 2031 can be connected to the base station housing 110 by screws, which is simple to connect and easy to disassemble.

[0060] See also Figures 2 to 4 In some embodiments, the disk body 2031 is provided with a plurality of avoidance holes 2033 arranged at intervals.

[0061] See also Figures 2 to 4 Optionally, the disk body 2031 is made of a hard material, and the covering portion 2012 is made of a soft material. After the covering portion 2012 wraps the disk body 2031, a plurality of avoidance holes 2033 are opened to allow the soft covering portion 2012 to fit tightly against the hard disk body 2031, thereby avoiding bulging of the covering portion 2012 or loose hard glue adhesion.

[0062] In some embodiments, the vacuum generator 202 includes a vacuum pump 2022 and an air release valve 2021 connected to the vacuum pump 2022. It is understandable that the vacuum pump 2022 may also be an air extraction pump, through which the air between the suction cup 201 and the ground can be extracted.

[0063] In this embodiment, the vacuum pump 2022 is a small vacuum pump, which is a vacuum pumping device with small size, light weight and low power consumption, and is suitable for applications with small size and low power consumption such as the base station housing 110. It has the following characteristics:

[0064] Compact design: The small vacuum pump is usually small in size and can be easily carried and installed in the limited space of the base station housing 110.

[0065] Low power consumption: The small vacuum pump adopts a high-efficiency drive device and energy-saving design with low power consumption, which can save energy and reduce operating costs.

[0066] Quiet operation: Small vacuum pumps usually adopt low noise design, which makes low noise during operation and will not cause interference to the surrounding environment and personnel.

[0067] See also Figures 2 to 4Optionally, the vacuum pump 2022 can be connected to the suction cup 201 through the air pipe 21, and the air release valve 2021 is normally in an open state. The air pipe is a three-way air pipe, wherein one branch of the three-way air pipe is connected to the suction cup 201, and the other two branch pipes of the three-way air pipe are connected to the vacuum pump 2022 and the air release valve 2021 respectively.

[0068] It can be understood that the vacuum pump 2022 and the air release valve 2021 are arranged in pairs, and two pairs are arranged, two three-way air pipes are arranged, and the two vacuum pumps 2022 control the two suction cups 201 through two three-way air pipes respectively.

[0069] When the window cleaning machine 130 starts working, the air release valve 2021 is closed, the vacuum pump 2022 starts working, and starts to evacuate the suction cup 201, thereby generating negative pressure to ensure that the window cleaning base station 100 can be firmly adsorbed on the ground.

[0070] When the window cleaning machine 130 completes its operation, the air release valve 2021 opens, and the suction cup 201 is connected to the external space through the air release valve 2021. The external gas enters the suction cup 201, so that the air pressure between the suction cup 201 and the ground returns to normal pressure, thereby releasing the vacuum adsorption effect between the window cleaning base station 100 and the ground, making it convenient for the user to lift the window cleaning base station 100.

[0071] See also Figures 2 to 4 In some embodiments, the window cleaning base station 100 further includes a winding wheel 300 disposed in the base station housing 110, and the winding wheel 300 is used to wind up the power cord or unwind the power cord.

[0072] It can be understood that the winding wheel 300 can realize the winding and unwinding of the power cord, thereby improving the convenience of use.

[0073] See also Figure 5 The present invention also proposes a window cleaning system 120, which includes a window cleaning base station 100. The specific structure of the window cleaning base station 100 refers to the above embodiment. Since the window cleaning system 120 adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.
