At the same time, if the window cleaning machine crashes, the stable setting of the base station can enable the safety rope to hold the window cleaning machine to prevent it from falling to the ground. After the window cleaning operation is completed, the base station needs to be able to immediately disconnect itself from the ground for sorting and storage, thereby improving the convenience of use.

[0031] See also Figure 1 to Figure 2 The embodiment of the present application provides a vacuum adsorption structure 100 and a window cleaning base station having the same. The window cleaning base station is used in conjunction with a window cleaning machine and includes a base station housing 110 having a accommodating cavity 111. The vacuum adsorption structure 100 is installed on the base station housing 110, so that the base station housing 110 can be adsorbed on the ground.

[0032] See also Figure 3 and Figure 4 The vacuum adsorption structure 100 includes a suction cup assembly 200 and a vacuum generating assembly 202 .

[0033] See also Figure 3 and Figure 4The suction cup assembly 200 is used to vacuum-adsorb the base station housing 110 to the ground. Two suction cup assemblies 200 are arranged at intervals, and the two suction cup assemblies 200 are connected to the same surface of the base station housing 110. In this embodiment, when the base station housing 110 is arranged in a vertical direction, the two suction cup assemblies 200 are arranged on the lower surface of the base station housing 110, so that when the base station housing 110 is placed on the ground, the suction cup assembly 200 can abut the ground.

[0034] The vacuum generating assembly 202 is located in the accommodating chamber 111, and the vacuum generating assembly 202 includes an air pump 2022 and an air release valve 2021 connected to the air pump 2022;

[0035] See also Figure 3 and Figure 4 , wherein two vacuum generating assemblies 202 are provided, and the two vacuum generating assemblies 202 respectively control the two suction cup assemblies 200; when the suction cup assembly 200 abuts against the ground, the two air release valves 2021 are closed, and the two air pumps 2022 respectively extract the air between the two suction cup assemblies 200 and the ground, so that the base station housing 110 is vacuum-adsorbed on the ground; when the suction cup assembly 200 is detached from the ground, the two air release valves 2021 are opened, and air passes through the air release valves 2021 to release the vacuum adsorption between the two suction cup assemblies 200 and the ground

[0036] See also Figure 3 and Figure 4 In this embodiment, when the base station housing 110 is set on the ground in the vertical direction, the two air pumps 2022 respectively evacuate the two suction cup assemblies 200 at the same time, so that the base station housing 110 is adsorbed on the ground through the vacuum adsorption effect. The two suction cup assemblies 200 can be set to strengthen the connection between the base station housing 110 and the ground, and the two air pumps 2022 work at the same time, which can achieve the rapid adsorption connection of the base station housing 110, improve the stability of the window cleaning base station, and improve the efficiency of the connection. After the window cleaning machine completes the operation, air is introduced into the two suction cup assemblies 200 through the two air release valves 2021, so that the vacuum adsorption effect can be quickly released, so that the base station housing 110 can be easily lifted, which improves the convenience of using the window cleaning base station.

[0037] See also Figure 3 and Figure 4It can be understood that in the embodiment of the present application, two adsorption components are arranged on the base station housing 110, and the double air pump 2022 and the double air release valve 2021 are used to respectively control the vacuum adsorption of the two suction cup components 200, or the release of the vacuum adsorption, thereby improving the stability of the base station housing 110 adsorbed on the ground, and the speed of adsorption and air release. The double air pump 2022 can ensure the vacuuming speed of the suction cup component 200 during vacuuming. At the same time, the double suction cup component 200 makes the base station housing 110 adsorbed more firmly. After pressing the button arranged on the base station housing 110, the double air release valve 2021 can respectively control the ventilation of the two suction cup components 200, so that the vacuum adsorption of the suction cup component 200 can be quickly removed.

[0038] See also Figure 3 and Figure 4 In some embodiments, the vacuum pump 2022 may be a vacuum pump. In this embodiment, the vacuum pump is a small vacuum pump. A small vacuum pump 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:

[0039] 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.

[0040] 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.

[0041] 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.

[0042] See also Figure 3 and Figure 4 Optionally, the vacuum pump can be connected to the suction cup assembly 200 through the air pipe 21, and the normal state of the air release valve 2021 is an open state. The air pipe 21 is a three-way air pipe 21, and two vacuum generating assemblies 202 are respectively provided with two or three-way air pipes 21. Among them, one branch of the three-way air pipe 21 is connected to the suction cup assembly 200, and the other two branch pipes of the three-way air pipe 21 are respectively connected to the vacuum pump and the air release valve 2021.

[0043] When the window cleaning machine starts working, the air release valve 2021 is closed, the vacuum pump starts working, and the suction cup assembly 200 begins to be evacuated, thereby generating negative pressure to ensure that the window cleaning base station can be firmly adsorbed on the ground.

[0044] See also Figure 3 and Figure 4When the window cleaning machine completes its operation, the air relief valve 2021 opens, and the air relief valve 2021 connects the suction cup assembly 200 to the external space through the three-way air pipe 21. The external gas enters the area between the suction cup assembly 200 and the ground, so that the air pressure between the suction cup assembly 200 and the ground is restored to normal pressure, thereby releasing the vacuum adsorption effect and making it convenient for the user to lift the base station housing 110.

[0045] See also Figure 3 and Figure 4 In some embodiments, the vacuum adsorption structure 100 further includes a mounting bracket 300 located in the accommodating cavity 111 , wherein the mounting bracket 300 is connected to the bottom of the accommodating cavity 111 and is used to support the two vacuum generating components 202 .

[0046] See also Figure 3 and Figure 4 Optionally, the mounting bracket 300 can improve the stability of the air pump 2022, so that the air pump 2022 can operate stably during operation. The mounting bracket 300 can be detachably connected to the accommodating cavity 111 by screws, and the screw connection improves the convenience of disassembly and installation of the mounting bracket 300.

[0047] See also Figure 5 and Figure 6 In some embodiments, a mounting hole 303 is provided on the mounting bracket 300 , and two mounting holes 303 are provided at intervals. The two air pumps 2022 are respectively disposed in the two mounting holes 303 , and the two air relief valves 2021 are both connected to the mounting bracket 300 .

[0048] See also Figure 5 and Figure 6 Optionally, a support baffle 3011 is provided in the mounting hole 303, and support baffles 3011 are provided on both sides of the vacuum pump 2022 respectively. The support baffles 3011 can improve the structural strength of the mounting bracket 300, and can also support the vacuum pump 2022, thereby improving the working stability of the vacuum pump 2022.

[0049] See also Figure 3 and Figure 4 In some embodiments, the two mounting holes 303 are arranged in a direction perpendicular to the bottom of the accommodating cavity 111, so that the two vacuum pumps 2022 are stacked in the vertical direction, which can save the space in the accommodating cavity 111 along the horizontal direction, and is conducive to the compactness of the structure of the base station shell 110.

[0050] See also Figure 5 and Figure 6In some embodiments, the two mounting holes 303 are arranged in a direction parallel to the bottom of the accommodating cavity 111, so that the two vacuum pumps 2022 are arranged in parallel in the horizontal direction, which can save the space in the accommodating cavity 111 along the vertical direction, and is conducive to the compactness of the structure of the base station shell 110.

[0051] Optionally, the air release valve 2021 may be fixed to the mounting bracket 300 via an air release valve upper cover 2023 .

[0052] See also Figure 3 and Figure 6 In some embodiments, the mounting bracket 300 includes a bracket bottom cover 302 and a bracket upper cover 301 connected to the bracket bottom cover 302, the two air release valves 2021 are connected to the bracket upper cover 301, a portion of the mounting hole 303 is located at the bracket bottom cover 302, and another portion of the mounting hole 303 is located at the bracket upper cover 301.

[0053] Optionally, the bracket bottom cover 302 can be detachably connected to the bottom of the accommodating cavity 111 by means of threads, and the support bottom cover and the bracket upper cover 301 can also be detachably connected by means of screws, which is beneficial to improving the convenience of installation and maintenance of the vacuum pump 2022.

[0055] It is understandable that the air nozzle 204 connects the area between the suction cup 201 and the ground, so that the air pump 2022 can extract the air from the area through the air nozzle 204, or the air release valve 2021 can introduce air into the area through the air nozzle 204.

[0056] Optionally, 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 base station housing 110 is firmly fixed on the ground during operation.

[0057] When the window cleaning machine encounters an emergency during operation, such as unexpected loss of control or failure, the window cleaning base station can still remain firmly on the ground to prevent the window cleaning robot from falling, thereby minimizing the potential risk of personal injury.

[0058] See also Figure 5 and Figure 6Optionally, the suction cup 201 is made of a flexible material, so that the suction cup 201 can adapt to different shapes of the ground and fit the ground as much as possible through its own elastic deformation. 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:

[0059] 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.

[0060] 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.

[0061] 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.

[0062] See also Figure 5 and Figure 6 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 .

[0065] Optionally, the disc body 2031 may be made of hardware material or hard plastic, thereby improving the structural strength of the suction cup 201 .

[0066] See also Figure 5 and Figure 6 Optionally, the covering portion 2012 and the disk body 2031 are connected together by a sleeve beer process, and a threaded hole is opened 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.

[0068] See also Figure 5 and Figure 6 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.
