Description

Technical Field

[0001] This application relates to the field of window cleaning equipment, and in particular to a novel window cleaning device. Background Technology

[0002] As people's living standards improve, more and more families are starting to use various cleaning devices, such as robot vacuums and window cleaning robots, to reduce labor intensity and improve their quality of life. Taking window cleaning robots as an example, a cleaning cloth is attached to the underside of the robot. The robot uses negative pressure generated by a fan to adhere to the glass. The pressure generated by the negative pressure acts on the cleaning cloth and the glass, and then the movement of the machine moves the cleaning cloth, thus wiping the glass.

[0003] However, existing window cleaning robots only effectively wipe the glass once during each pass, resulting in a low wiping frequency and often leaving the glass unclean. Summary of the Invention

[0004] In order to increase the frequency of wiping and make the wiped glass cleaner, this application provides a new type of window cleaning device.

[0005] The novel window cleaning device provided in this application adopts the following technical solution: A novel window cleaning device includes a wiping housing, a wiping mechanism, and a control mechanism. The wiping mechanism includes a wiping component, a traveling component, and a negative pressure component. The wiping component includes at least two wiping wheels and at least two wiping plates. Each wiping wheel is disposed on the wiping housing and located at the bottom of the wiping housing. Each wiping wheel includes a rotating part and a locking part. The rotating part is rotatably connected to the wiping housing, and the locking part is locked and fixed to the rotating part so that the wiping cloth is fixed to the wiping wheel. Each wiping plate is disposed on the bottom of the wiping housing and is used for wiping. Each wiping wheel is located between at least two oppositely disposed wiping plates. The traveling component is disposed on the wiping housing and is used for the automatic traveling of the wiping housing. The negative pressure component is disposed on the wiping housing and is used to make the wiping housing adhere to the window. The control mechanism is disposed on the wiping housing and is used to control the wiping mechanism.

[0006] Optionally, the wiping mechanism further includes at least two sets of driving components, each set of driving components driving each wiping wheel. Each driving component includes a driving gear, a driving gear ring, and a driving motor. The driving gear is rotatably mounted on the wiping housing, the driving gear ring is coaxially fixed with the rotating part, the driving gear ring meshes with the driving gear, and the driving motor is fixedly mounted on the wiping housing and used to drive the driving gear to rotate.

[0007] Optionally, the drive assembly further includes a drive worm gear and a drive worm, wherein the drive worm gear is coaxially fixed with the drive gear, and the drive worm is coaxially fixed with the output shaft of the drive motor, and the drive worm gear and the drive worm mesh.

[0008] Optionally, the walking assembly includes at least one walking wheel, each of which is rotatably connected to the bottom of the wiping housing, such that when each of the walking wheels rotates, it drives the wiping housing to move.

[0009] Optionally, the walking assembly further includes at least one set of walking components, each set of walking components being used to drive the rotation of each of the walking wheels. Each walking component includes a walking gear and a walking gear ring. The walking gear is coaxially fixed to the walking wheel, and the walking gear ring is coaxially fixed to the rotating part. The walking gear and the walking gear ring mesh.

[0010] Optionally, the negative pressure assembly includes a negative pressure motor. The inside of the wiping housing is provided with a negative pressure chamber, an adsorption duct, and an air outlet duct. The negative pressure motor is located in the negative pressure chamber. The adsorption duct is connected to the negative pressure chamber. Air outside the wiping housing is drawn into the negative pressure chamber through the adsorption duct. The air outlet duct is connected to the negative pressure chamber. Air in the negative pressure chamber flows out to the outside of the wiping housing through the air outlet duct.

[0011] Optionally, the wiping housing has multiple through-holes, each of which is connected to an air duct, and each wiping wheel is arranged around the outside of each air outlet.

[0012] Optionally, the negative pressure assembly further includes at least one set of sensing components, which include a sensing rod, a sensing spring, a sensing block, and a sensing module. The sensing rod is slidably fitted onto the wiping housing and is used to abut against the window. One end of the sensing spring abuts against the wiping housing, and the other end of the sensing spring abuts against the wiping rod. The sensing block is fixedly mounted on the sensing rod, and the sensing module is fixedly mounted on the wiping housing and is used to sense the position of the sensing block. When the sensing block is outside the sensing range of the sensing module, the rotation speed of the negative pressure motor increases, thereby increasing the suction force of the wiping housing on the window.

[0013] Optionally, the wiping mechanism further includes multiple water tank modules, each of which is disposed in the wiping housing. Each water tank module is capable of containing wiping agent and spraying the wiping agent onto the window being wiped.

[0014] Optionally, the top of the wiping housing is slidably fitted with a belt buckle, and the top of the wiping housing is provided with a wiping belt that is easy for the window cleaning equipment to pick up. One end of the wiping belt is fixedly connected to the wiping housing, and the other end of the wiping belt is fixedly connected to the belt buckle.

[0015] In summary, this application includes at least one of the following beneficial technical effects: When the window cleaning device needs to clean a window, the locking part is disengaged from the locking mechanism of the rotating part, allowing the cleaning cloth to be placed between the rotating part and the locking part. The locking part and rotating part are then re-locked in place, completing the installation of the cleaning cloth. The bottom of the window cleaning device is then placed against the window to be cleaned, allowing the device to adhere to the window via a negative pressure component. The traveling component then drives the window cleaning device, enabling it to move and clean the window. As the device moves, it moves the wiping plates, simulating a human hand wiping the window vertically or horizontally. During wiping, at least one wiping plate is positioned in the direction of travel of the window cleaning device. First, the window is wiped. Then, each wiping wheel rotates, driving the cloth to wipe the window. Next, at least one wiping plate wipes the window. This ensures that the window undergoes at least three wiping processes in one pass of the window cleaning equipment: wiping with the wiping plate, wiping with the wiping wheels and the cloth, and wiping with the wiping plate. This results in a higher wiping frequency for the window during one pass, making the glass cleaner. This improves upon existing window cleaning robots, which only perform one effective wipe per pass, resulting in a low wiping frequency and often leaving the glass uncleaned.

[0018] The following is in conjunction with the appendix Figures 1a to 10 This application will be described in further detail.

[0019] This application discloses a novel window cleaning device. (Refer to...) Figure 1a , Figure 1b as well as Figure 2 A novel window cleaning device includes a wiping housing 1, a wiping mechanism 2, and a control mechanism 3. The wiping mechanism 2 is disposed in the wiping housing 1 and is used to wipe the window, and the control mechanism 3 is disposed in the wiping housing 1 and is used to control the wiping mechanism 2.

[0020] Reference Figure 1a and Figure 1b In this embodiment, the bottom of the wiping housing 1 is square, and elastic anti-collision rings 11 are fixedly provided at the four corners of the bottom of the wiping housing 1 to reduce the damage to the window cleaning equipment when it collides with objects such as windows. The top of the wiping housing 1 is slidably fitted with a belt buckle 12, and the top of the wiping housing 1 is provided with a wiping belt 13 for easy handling by the window cleaning equipment. One end of the wiping belt 13 is fixedly connected to the wiping housing 1, and the other end of the wiping belt 13 is fixedly connected to the belt buckle 12. The top of the wiping housing 1 can be provided with a belt groove 14 for easy lifting of the wiping belt 13, and the belt groove 14 is located at the bottom of the wiping belt 13.

[0021] Reference Figures 3 to 6In this embodiment, the wiping mechanism 2 includes a wiping assembly 21, which includes two wiping wheels 211 and two wiping plates 212. Both wiping wheels 211 have a hollow annular shape and are disposed on the wiping housing 1 at its bottom. Each wiping wheel 211 includes a rotating part 2111 and a locking part 2112. The rotating part 2111 is rotatably connected to the wiping housing 1, and the locking part 2112 is locked and fixed to the rotating part 2111, thus fixing the cloth to the wiping wheel 211. The two wiping plates 212 are fixedly disposed at the bottom of the wiping housing 1 and used for wiping. 2 can also slide and fit on the bottom of the wiping housing 1 for wiping. This application embodiment does not limit this. The two wiping plates 212 are located on opposite sides of the bottom of the wiping housing 1. In this application embodiment, the direction in which the two wiping plates 212 face each other is set as the wiping direction, so that the two wiping plates 212 are set facing each other. The two wiping wheels 211 are located between the two wiping plates 212, so that when the window cleaning device wipes along the wiping direction, the window cleaning process of the window cleaning device is one wiping plate 212 wiping, the wiping wheel 211 driving the cloth to wipe, and the other wiping plate 212 wiping, so that the window cleaning device wipes the window more cleanly.

[0022] Reference Figure 7 In this embodiment, the wiping mechanism 2 further includes two sets of driving components 22, both of which are disposed inside the wiping housing 1. The two sets of driving components 22 drive the two wiping wheels 211 respectively. Each driving component 22 includes a driving gear 221, a driving gear ring 222, a driving motor 223, a driving worm gear 224, and a driving worm 225. The driving gear 221 is rotatably mounted on the wiping housing 1. The driving gear ring 222 is coaxially fixed with the rotating part 2111, and the driving gear ring 222 meshes with the driving gear 221. The driving motor 223 is fixedly mounted on the wiping housing 1. The driving worm gear 224 meshes with the driving gear. 221 is coaxially fixed, and the drive worm 225 is coaxially fixed with the output shaft of the drive motor 223. The drive worm wheel 224 meshes with the drive worm 225 so that when the wiping wheel 211 drives the wiping cloth to rotate and wipe, the drive motor 223 drives the output shaft of the drive motor 223 to rotate, the drive worm 225 drives the drive worm wheel 224 to rotate, the drive worm wheel 224 drives the drive gear 221 to rotate, the drive gear 221 drives the drive gear ring 222 to rotate, and the drive gear ring 222 drives the rotating part 2111 to rotate, thereby completing the drive of the wiping wheel 211 to rotate and wipe.

[0023] Reference Figure 6 and Figure 7In this embodiment of the application, the wiping mechanism 2 further includes a walking component 23, which includes two walking wheels 231. Both walking wheels 231 are rotatably connected to the bottom of the wiping housing 1, and the rotation axes of the two walking wheels 231 are located on the same straight line, so that when the two walking wheels 231 rotate, the two walking wheels 231 drive the wiping housing 1 to move.

[0024] Reference Figure 6 and Figure 7 In a further embodiment, the walking assembly 23 further includes two sets of walking components 232. The two sets of walking components 232 are used to drive each walking wheel 231 to rotate. The walking component 232 includes a walking gear 2321 and a walking gear ring 2322. The walking gear 2321 is coaxially fixed to the walking wheel 231, and the walking gear ring 2322 is coaxially fixed to the rotating part 2111. The walking gear 2321 and the walking gear ring 2322 mesh so that when the driving assembly 22 drives the wiping wheel 211 to rotate, the wiping wheel 211 rotates, which drives the walking gear ring 2322 to rotate, the walking gear ring 2322 rotates, which drives the walking gear 2321 to rotate, and the walking gear 2321 rotates, which drives the walking wheel 231 to rotate, thereby completing the driving of the walking wheel 231 to rotate.

[0025] Reference Figure 3 and Figure 8 In this embodiment, the wiping mechanism 2 further includes a negative pressure component 24, which includes a negative pressure motor 241. The wiping housing 1 has a negative pressure chamber 101, an adsorption duct 102, and an air outlet duct 103 inside. The negative pressure motor 241 is disposed in the negative pressure chamber 101. The adsorption duct 102 is connected to the negative pressure chamber 101. Air outside the wiping housing 1 is drawn into the negative pressure chamber 101 through the adsorption duct 102. The air outlet duct 103 is connected to the negative pressure chamber 101. Air in the negative pressure chamber 101 flows out to the outside of the wiping housing 1 through the air outlet duct 103. In a further embodiment, the wiping housing 1 has a plurality of through-hole air outlets 104. Each air outlet 104 is connected to the air outlet duct 103. Each wiping wheel 211 is respectively surrounded outside each air outlet 104, thereby assisting the wiping wheel 211 in wiping the window.

[0026] Reference Figure 9 and Figure 10In a further embodiment, the negative pressure assembly 24 further includes four sets of sensing components 242. Each set of sensing components 242 is respectively disposed at the four corner positions of the wiping housing 1. The sensing component 242 includes a sensing rod 2421, a sensing spring 2422, a sensing block 2423, and a sensing module 2424. The sensing rod 2421 is slidably fitted into the wiping housing 1 and used to abut against the window. The sensing rod 2421 is coaxially arranged with the anti-collision ring 11. One end of the sensing spring 2422 abuts against the wiping housing 1, and the other end of the sensing spring 2422 abuts against the wiping rod. The sensing block 2423 is fixedly disposed at one end of the sensing rod 2421. The sensing module 2424 is fixedly disposed in the wiping housing 1 and used to sense the position of the sensing block 2423. When the sensing block 2423... When the window is outside the sensing range of the sensing module 2424, the speed of the negative pressure motor 241 increases, thereby increasing the adsorption force of the wiping housing 1 on the window. When the negative pressure assembly 24 is working, the negative pressure motor 241 rotates to generate negative pressure so that the window cleaning device adsorbs onto the window. Each sensing rod 2421 first comes into contact with the window. As the wiping housing 1 gradually approaches the window with the increase of the adsorption force generated by the negative pressure assembly 24, each sensing rod 2421 drives each sensing block 2423 to move towards the sensing module 2424 until each sensing block 2423 enters the sensing range of the sensing module 2424. Then the speed of the negative pressure motor 241 is maintained within this range, so that the adsorption force generated by the negative pressure assembly 24 is always within a suitable range, thereby improving economic efficiency.

[0027] Reference Figure 2 In this embodiment, the wiping mechanism 2 further includes two water tank modules 25. Each water tank module 25 can contain wiping agent and spray the atomized or liquid wiping agent onto the window being wiped. Both water tank modules 25 are disposed on the wiping housing 1, and the two water tank modules 25 are respectively disposed on both sides of the wiping housing 1 in the wiping direction, so that the spraying direction of the wiping agent of the water tank module 25 is consistent with the wiping direction of the window wiping device.

[0028] Reference Figure 2 In this embodiment, the control mechanism 3 includes a control motherboard 31, a button motherboard 32, and a battery module 33. The control motherboard 31 is fixedly disposed inside the wiping housing 1. The control motherboard 31 is electrically connected to the drive motor 223, the negative pressure motor 241, the induction module 2424, and the water tank module 25. The button motherboard 32 is fixedly disposed inside the wiping housing 1 and electrically connected to the control motherboard 31. The button motherboard 32 is fixedly and electrically connected to a control button 321, which is used to control the opening or closing of the window cleaning device. The battery module 33 is fixedly disposed inside the wiping housing 1 and electrically connected to the control motherboard 31.

[0029] The implementation principle of a novel window cleaning device according to an embodiment of this application is as follows: When the window cleaning device needs to clean the window, the locking part 2112 is disengaged from the locking and fixing of the rotating part 2111, thereby placing the cleaning cloth between the rotating part 2111 and the locking part 2112. Then, the locking part 2112 and the rotating part 2111 are re-locked and fixed, thereby completing the installation of the cleaning cloth. Then, the bottom of the window cleaning device is placed against the window to be cleaned, and the window cleaning device is attracted to the window by the negative pressure component 24. Then, the walking component 23 drives the window cleaning device, thereby making the window cleaning device walk and clean the window. When the window cleaning device walks, it drives each wiping plate 212 to simulate a human hand to wipe the window up and down or left and right. And when wiping, at least A wiping plate 212 located in the direction of travel of the window cleaning equipment first wipes the window. Then, each wiping wheel 211 rotates and drives the wiping cloth to rotate and wipe the window. Then, at least one wiping plate 212 wipes the window again. Thus, the window undergoes at least three wipes in one round of wiping by the window cleaning equipment: one wiping plate 212, one wiping wheel 211 driving the wiping cloth, and another wiping plate 212. This makes the window more frequently wiped during one round of wiping by the window cleaning equipment, resulting in cleaner glass. This improves upon existing window cleaning robots, which only effectively wipe the glass once during one round of wiping, resulting in a low wiping frequency and often leaving the glass unclean.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
