Those skilled in the art will understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit differences. It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way. In the embodiments of the present application, "at least one" refers to one or more, and "more" refers to two or more.

[0052] It should be noted that the "at..." in the embodiments of the present application can mean the instant a certain situation occurs, or a period of time after the situation occurs, and the embodiments of the present application do not specifically limit this. In addition, the window wiping tool provided in the embodiments of the present application is only an example, and the window wiping tool may also include more or less content.

[0053] The technical solutions of the embodiments of the present application are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0054] In order to clearly understand the technical solutions of the embodiments of the present application, the solutions of the prior art are first introduced in detail. Glass and mesh windows are prone to dust and foreign matter, etc. If they are not wiped in time, the light transmittance and aesthetics of the windows will be affected. Common window opening methods for windows in high-rise buildings include sliding windows, casement windows, hanging windows and rotating windows; however, when the horizontal and / or vertical dimensions of the windows are larger than the length of the cleaning staff's arms, the outer surfaces of sliding windows, outward-opening casement windows and hanging windows need to be wiped with special wiping tools.

[0055] Existing cleaning tools include magnetic window cleaners and telescopic window cleaners. However, magnetic window cleaners are primarily suitable for large, flat glass windows of moderate thickness, limiting their application scenarios. They cannot clean screen windows, thin, thick, or unevenly thick flat glass windows, or slightly curved glass windows. Telescopic window cleaners require more arm space and cannot fully clean certain areas of the window, such as the overlapping area between two windows or the edge areas away from the window opening, resulting in poor cleaning results. Furthermore, telescopic window cleaners have limited functionality: some can only wipe glass, some can only scrape water, and some have fixed, non-adjustable brush rods, requiring only one type of telescopic window cleaner to be used. Furthermore, telescopic window cleaners require cleaners to stand at a higher position and / or extend their body to operate, making them difficult to operate and prone to accidents.

[0056] Based on this, an embodiment of the present application provides a window wiping tool that can be used in the field of cleaning technology, aiming to solve the above-mentioned problems existing in existing wiping tools.

[0057] The following introduces the application scenarios of the window wiping tool provided in the embodiments of the present application. Figure 1 This is an application scenario of the window wiping tool provided in the embodiment of the present application. Figure 1 As shown, the application scenario includes: a window wiping tool and a window 400; wherein, the window wiping tool includes: a guide system 100, a brush rod system 200 and a brush head system 300.

[0058] When wiping the window 400, the guide system 100 is clamped on the side frame of the window 400 to keep itself stationary relative to the window 400 and guide the brush rod system 200; the cleaning staff pushes and pulls the brush rod system 200, driving the brush head system 300 installed on the brush rod system 200 to wipe the surface of one side of the window 400.

[0059] The type of window 400 can be a glass window or a mesh window; in this application scenario,

[0060] If the window 400 is opened as a sliding window, the guide system 100 can be clamped on the vertical frame of the window 400 on the side away from the adjacent window. The guide system 100 can provide horizontal guidance for the brush rod system 200, and the cleaning staff can push and pull the brush rod system 200 in the horizontal direction; the brush head system 300 can wipe the outer surface of the window 400. When the position of the inner surface of the window 400 is limited (for example, the window 400 is arranged in the stairwell), the brush head system 300 can also wipe the inner surface of the window 400.

[0061] In other application scenarios, the window 400 can also be opened as a casement window, in which case the guide system 100 can be clamped on the vertical frame of the window 400 on the side away from the window rotation axis, and the guide system 100 can provide horizontal guidance for the brush rod system 200, and the cleaning staff can push and pull the brush rod system 200 in the horizontal direction; the window 400 can also be opened as a hanging window, in which case the guide system 100 can be clamped on the horizontal frame of the window 400 on the side away from the window rotation axis, and the guide system 100 can provide vertical guidance for the brush rod system 200, and the cleaning staff can push and pull the brush rod system 200 in the vertical direction.

[0062] The following combination Figure 1 The application scenarios and the accompanying drawings of the specification introduce the embodiments of the present application.

[0063] Figure 2 This is a schematic diagram of the structure of the window cleaning tool provided in the embodiment of the present application. Figure 2 As shown, in this embodiment, the window wiping tool includes: a guide system 100, a brush rod system 200 and a brush head system 300;

[0064] The guiding system 100 includes a clamping device 110 and a guiding device 120;

[0065] The clamping device 110 is used to clamp a side frame of the window 400 to ensure relative stillness between the clamping device 110 and the window 400 .

[0066] Specifically, the frame of the clamping window 400 is in the shape of a rectangle. To clamp the frame on one side of the clamping window 400, the clamping device 110 may be a flat clamp, a V-shaped clamp, a chuck or a non-standardized clamp.

[0067] When the clamping device 110 is clamped at the first position of the vertical frame on one side of the clamping window 400, the brush head system 300 wipes the first area of ​​the clamping window 400 (the first position refers to the first area of ​​the vertical frame). Figure 1 The first area refers to the area that can be wiped by the brush head system 300 in the first position. After wiping the first area, the clamping device 110 needs to be clamped to the second position of the frame to wipe the second area of ​​the clamped window 400 (the second position refers to a position a certain distance directly below the first position, and the second area refers to the area that can be wiped by the brush head system 300 in the second position). The movement of the clamping device 110 from the first position to the second position can be achieved by repositioning and clamping the clamping device 110, or by selecting an adjustable clamp as the clamping device 110.

[0068] The guide device 120 is mounted on the clamping device 110 . A cylindrical through hole 121 is formed on the guide device 120 . The brush rod system 200 is in guiding cooperation with the cylindrical through hole 121 .

[0069] Specifically, the guide device 120 is mounted on the clamping device 110, wherein the guide device 120 can be fixedly mounted on the clamping device 110 and remain stationary relative to the clamping device 110. The guide device 120 can also be rotatably mounted on the clamping device 110 and rotate relative to the clamping device 110, so that the brush head system 300 can wipe the clamped window 400 in a horizontal direction or in an inclined direction. At the same time, when cleaning the brush head of the brush head system 300, the guide device 120 is rotated until the brush head system 300 is separated from the area where the window 400 is located, without having to remove the clamping device 110 from the frame. The guide device 120 can also be mounted on the clamping device 110. The guide device 120 can translate relative to the guide system 100, thereby adjusting the distance between the brush rod system 200 and the window surface. When the distance is increased, the brush head system 300 can be cleaned more easily, while when the distance is shortened, the brush head system 300 can be kept in close contact with the window surface. The guide device 120 can also be mounted on the clamping device 110 with multiple degrees of freedom. The guide device 120 can perform compound motion relative to the clamping device 110, that is, simultaneous rotational motion and translational motion. This embodiment will not be further described.

[0070] The cylindrical through-hole 121 defined in the guide device 120 can be guided by a smooth surface, a sliding bearing, a linear guide, a guide sleeve, or an elastic element. The guide can be removable or non-removable. To facilitate storage and organization of the window cleaning tool, the brush rod system 200 and the cylindrical through-hole 121 can be engaged by a smooth surface or a sliding bearing with a clearance fit. Furthermore, the brush rod system 200 can consist not only of a single, integral brush rod, but also of multiple segmented brush rods of the same diameter. For storage and organization, these segmented brush rods only need to be disassembled.

[0071] The brush head system 300 includes: a pressing device 310 and a brush head device 320;

[0072] One side of the pressing device 310 is mounted on one end of the brush rod system 200;

[0073] The brush head device 320 is installed on the other side of the pressing device 310 . When the pressing device 310 is in the pressing state, the pressing device 310 is used to press the brush head device 320 against one side surface of the window 400 through the brush rod system 200 .

[0074] Specifically, the pressing device 310 presses the brush head device 320 against the surface of one side of the clamping window 400. The type of the pressing device 310 can be a spring pressing mechanism, an oil medium pressing mechanism or a pneumatic pressing mechanism.

[0075] The pressing device 310 can only be in the pressing state, and the pressing and releasing of the brush head device 320 are controlled by the translation of the guide device 120 relative to the clamping device 110. The pressing device 310 can also freely enter or exit the pressing state. When the pressing device 310 exits the pressing state, the brush head device 320 is released by rotating the guide device 120 relative to the clamping device 110. The pressing device 310 can enter or exit the pressing state manually, by wire control, or by motor control.

[0076] The pressing stroke of the pressing device 310 can be fixed or adjustable. When the stroke is fixed, the brush head device 320 can wipe flat glass windows of uniform thickness and screen windows; when the stroke is adjustable, the brush head device 320 can also wipe flat glass windows of uneven thickness and slightly curved glass windows.

[0077] For the brush bar system 200, the pressing device 310 compresses the brush head device 320 under the action of the brush bar system 200, which requires the brush bar system 200 to have a certain degree of rigidity. Considering that the cylindrical through-hole 121 not only limits the movement direction of the brush bar system 200 but also provides support for the brush bar system 200, the length of the cylindrical through-hole 121 can be increased to improve the rigidity of the brush bar system 200. At the same time, considering that the window wiping tool is supported by the clamping device 110 rather than the cleaning person, the wall thickness and material strength of the brush bar system 200 can be increased to improve the rigidity of the brush bar system 200.

[0078] The brush head assembly 320 mounted on the clamping device 310 can have a fixed or adjustable angle relative to the clamping device 310 or the brush bar system 200. When the angle is adjustable, the brush head assembly 320 can better conform to the surface of the clamped window 400, enhancing the cleaning effect of the clamped window 400. Furthermore, when cleaning the brush head, the brush head assembly 320 can be rotated to a position that is convenient for the cleaning staff, thereby improving the cleaning efficiency of the brush head. To further enhance cleaning efficiency and functionality, the brush head of the brush head assembly 320 is removable and replaceable.

[0079] The embodiment of the present application provides a window cleaning tool, which includes a guide system, a brush rod system, and a brush head system. The guide system includes a clamping device for clamping a side frame of a window, and a guide device installed on the clamping device. The guide device is provided with a cylindrical through-hole, and the brush rod system and the cylindrical through-hole are guided and matched. The brush head system includes a clamping device installed at one end of the brush rod system, and a brush head device installed at the other side of the clamping device. When the clamping device is in a clamping state, the clamping device is used to press the brush head device against the side surface of the window through the brush rod system. The following technical effects are achieved: when the clamping device is in a clamping state, the clamping device is used to press the brush head device against the side surface of the clamped window through the brush rod system, and the tool is suitable for a variety of application scenarios. The cleaning staff only needs to push and pull the brush rod system and move the clamping device, which requires less arm space and can wipe the entire area of ​​the window, with a strong cleaning effect. The cylindrical through-hole supports the brush rod system, improves the rigidity of the brush rod system, and further improves the fit between the brush head device and the clamped window.

[0080] Figure 3 A schematic diagram of the structure of the guide system provided in the embodiment of the present application. Taking into account the different frame thicknesses of different windows, for example, the frame thickness of mesh windows is usually thinner, the frame thickness of single-layer glass windows is usually moderate, and the frame thickness of multi-layer insulating glass is usually thicker, in order to improve the applicability of the clamping device, it is necessary to select a clamp with adjustable thickness; at the same time, considering that the repositioning and clamping operations are more complicated when the clamping position of the clamping device is changed, in order to reduce the difficulty of operating the clamping device, it is necessary to select a clamp with adjustable clamping position. Based on the above concept, as Figure 3 As shown, this embodiment provides a guidance system, which is in the present application Figure 2 The embodiment provides a further refinement of the guide system of the window wiping tool.

[0081] The clamping device 110 includes: an adjustable thickness clamping member 111, a first push-pull handle 112, a plurality of first rolling members 113, and a plurality of second rolling members 114;

[0082] A plurality of first rolling members 113 and a plurality of second rolling members 114 are mounted on the inner surface of the adjustable thickness clamping member 111. The adjustable thickness clamping member 111 is used to clamp a side frame of the window 400 through the plurality of first rolling members 113 and prevent the cylindrical through-hole 121 from tilting through the plurality of second rolling members 114.

[0083] The first push-pull handle 112 is installed on the outer surface of the thickness-adjustable clamping component 111 . The thickness-adjustable clamping component 111 is also used to slide on one side frame of the window 400 through the first push-pull handle 112 and the plurality of first rolling components 113 .

[0084] Specifically, the adjustable-thickness clamping member 111 adjusts its thickness according to the thickness of the frame of the window 400 to clamp one side of the frame of the window 400. The adjustable-thickness clamping member 111 can be a flat clamp using a clamping plate and bolts to achieve clamping, a V-shaped clamp with a customized V-groove size, a chuck with adjustable jaw opening, or a dedicated non-standard clamp.

[0085] The clamping position of the adjustable-thickness clamping member 111 can be adjusted through the friction of the multiple first rolling members 113. One of the front and back surfaces of the side frame of the window 400 can be in smooth contact with the adjustable-thickness clamping member 111, while the other surface is in rolling contact with the adjustable-thickness clamping member 111 via the multiple first rolling members 113. Alternatively, both the front and back surfaces of the side frame of the window 400 are in rolling contact with the adjustable-thickness clamping member 111 via the multiple first rolling members 113. Taking the latter as an example, when the weight of the window cleaning tool is equal to the static friction of the multiple first rolling members 113, the adjustable-thickness clamping member 111 remains stationary relative to the window 400. When the external force applied to the adjustable-thickness clamping member 111 is greater than the combined force of the weight and the rolling friction of the multiple first rolling members 113, the adjustable-thickness clamping member 111 slides relative to the window 400.

[0086] The external force on the adjustable thickness clamping member 111 is applied by the first push-pull handle 112. Specifically, when the cleaning staff pushes the first push-pull handle 112 upward, the first push-pull handle 112 applies an upward push force to the adjustable thickness clamping member 111; when the cleaning staff pulls the first push-pull handle 112 downward, the first push-pull handle 112 applies a downward pull to the adjustable thickness clamping member 111. However, the direction of the push-pull force may be at a certain angle relative to the direction of gravity. This causes the adjustable thickness clamping member 111 to not only translate relative to the window 400 but also rotate relative to the window 400 when sliding. This in turn tilts the guide device 120 mounted on the adjustable thickness clamping member 111, thereby tilting the cylindrical through-hole 121 provided in the guide device 120. To this end, the side surface of the side frame of the window 400 is in rolling contact with the adjustable thickness clamping member 111 via a plurality of second rolling members 114 to prevent the cylindrical through-hole 121 from tilting.

[0087] The technical effect of this embodiment is: the thickness of the clamping device is adjusted by the adjustable thickness clamping component, and the sliding of the adjustable thickness clamping component relative to the window is achieved through the first push-pull handle, multiple first rolling components and multiple second rolling components, thereby achieving the clamping position adjustment of the clamping device.

[0088] In other embodiments, the adjustable thickness clamping component can also adjust the clamping position through a suction cup structure; when the window frame is made of metal, the adjustable thickness clamping component can also adjust the clamping position through an electromagnet structure.

[0089] In one possible design, the adjustable thickness clamping component 111 is a flat clamp that is clamped by a clamping plate and a bolt. To achieve an adjustable clamping position of the adjustable thickness clamping component 111, the adjustable thickness clamping component 111 includes: a clamping base 1111, a clamping plate 1112, a tightening bolt 1113, and a tightening handle 1114.

[0090] The shape of the clamping base 1111 is a groove;

[0091] The clamping plate 1112 is mounted on the inner first surface of the clamping base 1111 via a tightening bolt 1113 , and the tightening handle 1114 is used to adjust the stroke of the clamping plate 1112 to adjust the thickness of the adjustable thickness clamping member 111 ;

[0092] A portion of the first rolling component 113 is installed on the clamping plate 1112, another portion of the first rolling component 113 is installed on the inner second surface of the clamping base 1111, and multiple second rolling components 114 are installed on the inner third surface of the clamping base 1111; wherein the inner second surface is parallel to the inner first surface, and the inner third surface is perpendicular to the inner first surface.

[0093] Specifically, the clamping plate 1112 divides the cavity of the clamping base 1111 into two areas (the clamping plate 1112 and the tightening bolt 1113 are located in the Figure 3 In the partial cross-section of the figure, one side frame of the window 400 is installed in one area, and the other area is installed with a tightening bolt 1113. The cleaning staff rotates the tightening handle 1114 to change the stroke of the clamping plate 1112 through the tightening bolt 1113, thereby changing the thickness of the area, that is, the thickness of the adjustable thickness clamping component 111, thereby achieving clamping of one side edge of the window 400.

[0094] The front and back surfaces of the side frame of the window 400 are in rolling contact with the clamping base 1111 and the clamping plate 1112 through a plurality of first rolling components 113. In order to improve the stability of the clamping force and the smoothness of the sliding, a portion of the first rolling components 113 is mounted on the clamping plate 1112, and another portion of the first rolling components 113 is mounted on the inner second surface of the clamping base 1111 (the inner second surface is the inner surface of the clamping base 1111 that is in rolling contact with one of the front and back surfaces of the side frame of the window 400; correspondingly, the inner first surface is the inner surface of the clamping base 1111 that is in rolling contact with the other of the front and back surfaces of the side frame of the window 400; the inner third surface is the inner surface of the clamping base 1111 that is in rolling contact with the side surface of the side frame of the window 400), and all the second rolling components 114 are mounted on the inner third surface of the clamping base 1111. The number distribution of the first rolling components 113 may be the same on both sides, or may be more on one side and less on the other side.

[0095] In other embodiments, the adjustable thickness clamping component 111 further includes a limiting sleeve, which is mounted on the inner first surface of the clamping base 1111 , and the clamping plate 1112 slides in the limiting sleeve via the tightening bolt 1113 .

[0096] The technical effect of this embodiment is: providing a flat plate clamp with adjustable clamping position, reducing the operating difficulty for cleaning personnel and thereby reducing the occurrence of operating accidents.

[0097] In a possible design, each first rolling component 113 is a wheel-type rolling component, and each second rolling component 114 is a ball-type rolling component.

[0098] Specifically, when the adjustable thickness clamping member 111 is stationary relative to the window 400, the first rolling member 113 needs to provide a larger static friction force to ensure that the static friction force is balanced with the force of gravity; when the adjustable thickness clamping member 111 slides relative to the window 400, the first rolling member 113 needs to provide a smaller rolling friction force to ensure that the cleaning staff can push and pull the second rolling member 114 with less effort. Therefore, a wheeled rolling member is selected as the first rolling member 113. Furthermore, considering that the frame surface of the window 400 may be sprayed with an organic or inorganic coating layer, and the frame surface of the window 400 may be stained with water stains and dirt, a conventional roller may not be able to provide sufficient static friction. Therefore, the roller surface of the first rolling member 113 may adopt a special texture or material, and / or the contact area between the roller and the frame surface of the window 400 may be increased.

[0099] The second rolling component 114 is used to support the adjustable thickness clamping component 111. A large rolling friction force will affect the cleaning staff in pushing and pulling the second rolling component 114, increasing the difficulty of operation. Therefore, a ball-type rolling component is selected as the second rolling component 114.

[0100] The technical effect of this embodiment is that the clamping component is ensured to be stationary relative to the window through the cooperation of the roller and the ball.

[0101] In one possible design, the guide system 100 further includes: a rotating device 130;

[0102] One side of the rotating device 130 is mounted on the outer surface of the thickness-adjustable clamping member 111 , and the guide device 120 is mounted on the other side of the rotating device 130 ;

[0103] The rotation angle of the rotating device 130 includes a first angle and a second angle;

[0104] When the rotation angle is set to the first angle and the pressing device 310 is in the pressing state, the pressing device 310 is used to press the brush head device 320 against the side surface of the window 400 through the brush rod system 200;

[0105] When the rotation angle is set to the second angle, the brush head device 320 is out of the area where the window 400 is located.

[0106] Specifically, the type of the rotating device 130 can be a bearing, a rotary joint, a universal joint or a turntable, etc. The guide device 120 can rotate relative to the clamping device 110 through the rotating device 130.

[0107] Setting the rotation angle of the rotating device 130 to the first angle or the second angle can be achieved through smooth rotation, and the rotating device 130 has no fixed angle limit. Furthermore, when the rotation angle is set to the first angle range and does not affect the pressing device 310 pressing the brush head device 320 and wiping the glass, it is considered to be set to the first angle, wherein the first angle range is an angle range that includes the first angle; accordingly, when the rotation angle is set to the second angle range, it is considered to be set to the second angle.

[0108] The rotation angle of the rotating device 130 can be set to the first angle or the second angle, which can also be achieved through step rotation, indexing rotation, or limited rotation. The rotating device 130 has a fixed angle limit or a fixed angle range limit. Furthermore, the rotation angle can also include multiple angles in addition to the first angle and the second angle. For example, the first angle is defined as 0° and the second angle is defined as 120° (when the brush head device 320 is diagonally upward and away from the area where the window 400 is located). When the clamping device 110 is in a lower position, the rotation angle is set to the second angle, which is more convenient for cleaning the brush head. In addition, a third angle, such as 240° (when the brush head device 320 is diagonally downward and away from the area where the window 400 is located), can be included. When the clamping device 110 is in a higher position, the rotation angle is set to the third angle, which is more convenient for cleaning the brush head.

[0109] The technical effect of this embodiment is that the brush head system is separated from the area where the window is located through the first angle and the second angle without removing the clamping device from the frame.

[0110] Figure 4 This is a schematic diagram of the structure of the brush rod system and brush head system provided in the embodiment of the present application. In order to improve the applicability of the window wiping tool and reduce the difficulty of operation for cleaning personnel, it is proposed to realize the free entry or exit of the clamping state of the clamping device through wire control. Based on the above concept, Figure 4 As shown, this embodiment provides a window wiping tool, which is in the present application Figure 2 and Figure 3 The window wiping tool provided in the embodiment is further refined based on the embodiment.

[0111] The brush head system 300 further includes: a universal device 330 and a wire control device 340;

[0112] One side of the universal device 330 is mounted on one end of the brush rod system 200; one side of the pressing device 310 is mounted on the other side of the universal device 330;

[0113] The wire control device 340 includes a wrench component 341, a control wire 342 and a locking component 343;

[0114] The wrench component 341 is mounted on the other end of the brush rod system 200 , and the locking component 343 is mounted on the pressing device 310 ;

[0115] The control line 342 connects the wrench component 341 and the locking component 343. When the wrench component 341 is pulled, the locking component 343 is used to control the pressing device 310 to enter or exit the pressing state.

[0116] Specifically, for the universal device 330, the type of the universal device 330 can be a connecting frame and pivot shaft structure, a spherical joint and socket structure, or a rotating shaft and bearing structure, etc. The clamping device 310 realizes multi-degree-of-freedom rotation relative to the brush rod system 200 through the universal device 330, thereby realizing flexible operation, uniform force and cleaning and replacement of the brush head device 320.

[0117] Regarding the wire control device 340, the wrench component 341 is installed at the end of the brush bar system 200 closest to the cleaning staff, making it easy for the cleaning staff to operate at any time. The locking component 343 can be installed between the clamping device 310 and the universal device 330, or it can be installed at other locations on the clamping device 310. The control wire 342 can pass through the inside or outside of the brush bar system 200 and the inside or outside of the universal device 330, connecting the wrench component 341 and the locking component 343. The type of the control wire 342 can be a non-metallic soft wire, a metal hard wire, or a pull wire with a sliding sleeve.

[0118] When the cleaning staff needs the clamping device 310 to exit the clamping state, they only need to press the locking wrench of the wrench component 341. The wrench component 341 pulls the control line 342 and then pulls the locking component 343, so that the locking component 343 locks the clamping device 310; correspondingly, when the cleaning staff needs the clamping device 310 to enter the clamping state, they only need to press the reset wrench of the wrench component 341. The wrench component 341 stops pulling the control line 342, and the locking component 343 stops locking the clamping device 310.

[0119] For example, wrench component 341 includes a locking wrench, a reset wrench, and a female buckle. The locking wrench includes a rotating shaft, a sub-buckle, and a first pull rope point. The female buckle includes a limit groove and a reset plate. One end of the control line 342 is connected to the first pull rope point. When the locking wrench is pressed, the first pull rope point rotates around the rotating shaft away from the locking component 343 until the sub-buckle is locked in the limit groove, thereby pulling the control line 342. The sub-buckle is located on one side of the reset plate, and the reset wrench is located on the other side of the reset plate. When the reset wrench is pressed, the reset wrench pushes the sub-buckle out of the limit groove through the reset plate, thus stopping the pulling of the control line 342.

[0120] The locking component 343 includes a stop plate and a second pull point, to which the other end of the control line 342 is connected. The clamping device 310 is a spring-loaded mechanism, with one end of the spring fixed to the base of the clamping device 310 and the other end fixed to the stop plate. When the control line 342 is pulled, the stop plate continuously compresses the spring, causing the clamping device 310 to lose its clamping capacity and exit the clamping state. When the control line 342 is no longer pulled, the stop plate stops compressing the spring, allowing the clamping device 310 to regain its clamping capacity and enter the clamping state.

[0121] The technical effect of this embodiment is that the clamping device is remotely controlled to enter or exit the clamping state through the wire control device, further reducing the operating difficulty for cleaning personnel.

[0122] In one possible design, the brush bar system 200 includes: a plurality of segmented brush bars 210;

[0123] A plurality of segmented brush rods 210 are coaxially arranged, and two adjacent segmented brush rods 210 are threadedly connected;

[0124] The guide device 120 further defines a cable through hole 122 , through which the control wire 342 passes.

[0125] Specifically, by using multiple segmented brush rods 210, the length of the brush rod system 200 can be freely adjusted according to the size of the window 400. When wiping a larger window 400, more segmented brush rods 210 are installed; when wiping a smaller window 400, fewer segmented brush rods 210 are installed. Figure 4 As shown, the brush bar system 200 is composed of six segmented brush bars 210.

[0126] However, the segmentation of the brush bar system 200 causes the length of the control wire 342 to change, and the control wire 342 passes through the interior of the brush bar system 200 to connect the wrench component 341 and the locking component 343, which makes the installation of the window wiping tool more complicated. Therefore, the control wire 342 is connected to the wrench component 341 and the locking component 343 by passing through the exterior of the brush bar system 200.

[0127] To prevent the control wire 342 from changing in length when it passes around the guide 120, thereby affecting the locking component 343's ability to lock or unlock the pressing device 310, a cable through-hole 122 is provided in the guide 120. The control wire 342 passes through the cable through-hole 122 without having to pass around the guide 120. Furthermore, the cable through-hole 122 is connected to the cylindrical through-hole 121 to ensure that the control wire 342 is flat.

[0128] The technical effect of this embodiment is: through the segmented brush rod, the length of the brush rod system can be freely adjusted, thereby improving the applicability of the window wiping tool; the flatness of the control line is ensured by the cable through-hole, thereby avoiding the control line bypassing the guide device and affecting the locking or unlocking of the clamping device by the locking component.

[0129] In one possible design, the brush bar system 200 further includes: a second push-pull handle 220;

[0130] Each segmented brush rod 210 is provided with a connection hole 211;

[0131] The second push-pull handle 220 is threadedly connected to the connecting hole 211 of the target segmented brush rod; wherein the target segmented brush rod is the last segmented brush rod 210 among the multiple segmented brush rods 210, starting from the segmented brush rod with the brush head system 300 installed.

[0132] Specifically, when the cleaning staff has more room to move their arms, they can connect the auxiliary push-pull device, that is, the second push-pull handle 220, to the target segmented brush rod. The window 400 can be wiped by pushing and pulling the second push-pull handle 220 without directly pushing and pulling the brush rod system 200, further reducing the difficulty of operation for the cleaning staff.

[0133] In other embodiments, when the brush rod system is composed of an integral brush rod, a connection hole 211 is provided at one end of the integral brush rod away from the brush head system.

[0134] In other embodiments, the wire control device 340 further includes a rope reel, and a certain point on the control line 342 is connected to the first rope pulling point, and the rope reel is used to store the untensioned control line.

[0135] In one possible design, the brush head system 300 further includes: a stroke adjustment device 350;

[0136] The stroke adjusting device 350 is installed on the pressing device 310 , and the stroke adjusting device 350 is used to adjust the stroke of the pressing device 310 .

[0137] Specifically, the cleaning staff adjusts the stroke of the pressing device 310 through the stroke adjustment device 350 to improve the application scenarios of the window wiping tool. For example, the stroke adjustment device 350 is a bolt tightening mechanism. The cleaning staff adjusts the stroke of the stroke adjustment device 350 to adjust the maximum distance between the limit plate of the locking component 343 and the base of the pressing device 310. When the distance is small, the stroke of the pressing device 310 is short, which is more suitable for scenarios where the distance between the window surface and the window frame is small. When the distance is large, the stroke of the pressing device 310 is large, which is more suitable for scenarios where the distance between the window surface and the window frame is large, as well as scenarios where the window surface and the window frame are large, and where the window is unevenly thick, flat glass windows and slightly curved glass windows are wiped.

[0138] The technical effect of this embodiment is: by adjusting the stroke of the clamping device through the stroke adjustment device, in some application scenarios, the pressure of the clamping device on the brush rod system is reduced, and the service life of the brush rod system is increased.

[0139] In a possible design, the brush head device 320 is installed with at least one of a plurality of brush heads; wherein the plurality of brush heads include: a bristle brush, a cloth brush, a roller brush and a scraper.

[0140] Specifically, the brush heads can be flexibly disassembled, replaced and combined. Cleaning staff can choose different types of brush heads according to different scenarios, which solves the problem of the relatively single function of the brush head device.

[0141] In other embodiments, the cleaning staff can select the brush head before installing the window wiping tool, or can replace the brush head when the rotation angle of the rotating device 130 is set to the second angle.

However, it is easy for those skilled in the art to understand that the scope of protection of the present application is obviously not limited to these specific embodiments.

Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solution to deviate from the scope of the technical solutions of the embodiments of the present application.
