Description

Technical Field

[0001] This invention relates to the field of window cleaning drone technology, specifically to a portable window cleaning robot with an adsorption-type self-propelled roller brush. Background Technology

[0002] With the acceleration of urbanization and the popularization of high-rise buildings, window cleaning robots, as an important branch of smart cleaning appliances, have seen increasing market demand year by year. Currently, window cleaning robot products on the market are mainly based on vacuum adsorption or fan adsorption principles to climb walls and complete cleaning operations by rotating a cloth or moving on a track.

[0003] Existing suction-type self-propelled window cleaning robots still have some problems. In order to accommodate large-capacity batteries, negative pressure fans and water tanks, the thickness of existing window cleaning robots is usually greater than 50mm and the weight is generally more than 1.5kg. This bulky design makes it impossible for users to hold it with one hand for a long time, and it is difficult to put it into ordinary backpacks or handbags. It cannot meet the portability needs of business travel, renting a house or moving in a vehicle. Therefore, those skilled in the art have provided suction-type self-propelled roller brush portable window cleaning robots to solve the problems mentioned in the background art. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a portable window cleaning robot with an adsorption-type self-propelled roller brush. This solves the problem that existing window cleaning robots, in order to accommodate large-capacity batteries, negative pressure fans, and water tanks, typically have a body thickness greater than 50mm and a weight generally exceeding 1.5kg. This bulky design makes it impossible for users to hold the robot with one hand for extended periods, and it is difficult to put it into ordinary backpacks or handbags, thus failing to meet the portability needs of travel, rented accommodation, or mobile vehicle scenarios.

[0005] (II) Technical Solution To achieve the above objectives, the present invention is implemented through the following technical solution: a portable window cleaning robot with an adsorption-type self-propelled roller brush, comprising a shell, a driving structure provided on both side walls of the shell, a cleaning structure provided on both the front and rear end faces of the shell, a water spraying structure provided on the upper end face of the shell, and an adsorption structure fixedly connected to the lower part of the interior of the shell. Taking the cleaning structure at the front as an example, the cleaning structure includes two arc-shaped frames. The two arc-shaped frames are rotatably connected to the lower sides of the front end face of the outer shell. The front end face of each of the two arc-shaped frames is fixedly connected to a mounting bracket. A cleaning brush is rotatably connected between the two mounting brackets. Flexible magnets are fixedly connected to the front end face of the outer shell at the upper end of the two arc-shaped frames. The water spraying structure includes a storage tank, and a lifting cover is slidably connected to the upper part of the storage tank. Grooves are provided on the lower part of the outer side wall of the lifting cover and the lower part of the inner side wall of the storage tank. Rubber connecting rings are provided inside the two grooves, and the two ends of the rubber connecting rings are respectively fixedly connected to the lower part of the inner side wall of the inner groove and the upper part of the inner side wall of the outer groove.

[0006] Preferably, a miniature water pump is fixedly connected to the center of the lower inner wall of the storage box. The output end of the miniature water pump passes through the front inner wall of the storage box and extends to the front end of the storage box, and a water pipe is fixedly connected to the end of the water pipe. A spray pipe is fixedly connected to the output end of the water pipe. Multiple spray holes are arranged horizontally on the lower end face of the spray pipe. A metal shaping tube is fixedly connected to the outer wall of the water pipe. The miniature water pump draws water from the bottom of the storage box, delivers it to the spray pipe through the water pipe, and sprays it out through the spray holes. The metal shaping tube wraps around the water pipe, and the user can adjust the spray angle and position of the spray pipe arbitrarily by bending the metal shaping tube. The setting of the metal shaping tube makes the spray angle freely adjustable, which can target and wet stubborn stains in a specific spot, while avoiding the disadvantage of traditional rigid water pipes that cannot be changed direction, thus improving the flexibility and coverage of cleaning.

[0007] Preferably, a water inlet is fixedly connected to the center of the upper end face of the lifting cover, and a threaded cap is threadedly fitted on the upper part of the outer side wall of the water inlet. A drain valve is fixedly connected to the lower part of one side of the rear end face of the storage tank. The cleaning fluid is injected into the storage tank through the water inlet, and the threaded cap is tightened to achieve a seal. When the equipment is idle or the cleaning fluid needs to be replaced, the drain valve is opened, and the residual liquid in the tank is discharged by gravity. The addition of a drain valve solves the problem of residual water inside the equipment deteriorating or freezing when the equipment is stored, effectively prevents bacterial growth, extends the service life of the micro water pump, and improves the hygiene standard of the equipment.

[0008] Preferably, buckles are fixedly connected to the upper center of both sides of the storage box, and hooks are fixedly connected to the upper sides of both sides of the lifting cover located above the two buckles. The cooperation between the buckles and the hooks ensures that the structure remains stable in the storage state and prevents the lifting cover from shaking when carried.

[0009] Preferably, taking one of the drive structures as an example, the drive structure includes multiple drive wheels arranged in a front-to-back manner and rotatably connected to the lower side wall of the outer casing. A miniature servo geared motor is fixedly connected to the side wall of the outer casing on the rearmost drive wheel. The output end of the miniature servo geared motor is fixedly connected to the rearmost drive wheel. A drive belt is sleeved on the outer side wall of the multiple drive wheels. A protective cover is fixedly connected to the side wall of the outer casing above the drive belt. The miniature servo geared motor outputs power to drive the drive wheel to rotate, and the power is synchronously transmitted to the other drive wheels through the drive belt to achieve multi-wheel synchronous drive. The protective cover covers the drive belt, isolating external dust and foreign objects, increasing the contact area and friction with the glass surface, and improving obstacle crossing ability and climbing stability.

[0010] Preferably, the adsorption structure includes a mounting plate, a frame fixedly sleeved on the outer wall of the mounting plate, a storage groove at the center of the lower end face of the frame, a rubber seat fixedly connected inside the storage groove, two negative pressure grooves concentrically formed near the edge of the lower end face of the rubber seat, negative pressure components are provided on the upper end face of the two negative pressure grooves and the mounting plate, four rigid magnets are fixedly connected in a rectangular arrangement on the lower end face of the mounting plate, and rubber pads are fixedly connected on the lower end face of the four rigid magnets. The three negative pressure components are responsible for drawing out the air inside the two negative pressure grooves and the rubber seat to form a negative pressure, increasing the adsorption force, and the multi-layer arrangement reduces the risk of air leakage and falling.

[0011] Preferably, taking one of the negative pressure components as an example, the negative pressure component includes a miniature air pump, the input end of which is fixedly connected to a pressure holding valve, and the input end of which is fixedly connected to a connecting pipe. When the miniature air pump draws air, the airflow pushes open the pressure holding valve to form a passage. When the equipment is powered off or the air pump stops working, the pressure holding valve automatically closes under its own weight and external atmospheric pressure, cutting off the passage between the outside world and the negative pressure tank. The pressure holding valve realizes the power failure self-locking function. In the event of an accidental power failure or equipment failure that causes a shutdown, it can instantly lock the negative pressure to prevent the equipment from falling due to loss of power, greatly ensuring the safety of high-altitude operations.

[0012] Preferably, a partition is fixedly connected to the center of the interior of the housing, and a battery module is fixedly connected to the upper surface of the partition. An integrated control chip is fixedly connected to the center of the upper surface of the battery module. The integrated control chip serves as the core processing unit, receiving sensor signals and controlling the power distribution of the battery module, coordinating the start-stop and speed of the micro servo geared motor, micro air pump, and micro water pump. Integrating the battery module and the integrated control chip on the partition optimizes the internal spatial layout of the body, achieves a high degree of centralization and modularization of electrical components, which helps to lower the center of gravity of the body and improve walking stability.

[0013] (III) Beneficial Effects This invention provides a portable window cleaning robot with an adsorption-type self-propelled roller brush. It has the following beneficial effects: 1. In this invention, when storing, the four arc-shaped frames are rotated to separate them from the flexible magnets. The frames are rotated to the bottom of the mounting plate, where they are attracted by the four hard magnets. The rubber pads reduce the impact of impacts. The remaining water inside the storage box is drained through the drain valve. The lifting cover is pressed down and locked by hanging the rods on the two buckles on the two hooks. After storage, the volume is reduced, making it easy to carry.

[0014] 2. In this invention, the micro air pump works by drawing air out of the two negative pressure grooves on the lower end face of the rubber seat through the connecting pipe and the pressure holding valve to form a negative pressure, so that the device is adsorbed onto the glass surface through the rubber seat. When the power is off, the pressure holding valve automatically closes to maintain the negative pressure and prevent it from falling. Moreover, the multi-layer design reduces the risk of air leakage and falling.

[0015] 3. In this invention, during the movement, the cleaning brush of the front cleaning structure rotates between the two mounting brackets to scrub the stains on the glass surface. The front soft brush and the rear silicone squeegee brush simultaneously squeegee the cleaned glass surface, making it easier to clean more thoroughly. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: like Figures 1-7 As shown, this embodiment of the invention provides a portable window cleaning robot with an adsorption-type self-propelled roller brush, including a shell 1, a drive structure 4 on both sides of the shell 1, a cleaning structure 3 on both the front and rear ends of the shell 1, a water spraying structure 2 on the upper end of the shell 1, and an adsorption structure 5 fixedly connected to the lower part of the interior of the shell 1.

[0020] Taking the front cleaning structure 3 as an example, the cleaning structure 3 includes two arc-shaped frames 301. The two arc-shaped frames 301 are rotatably connected to the lower sides of the front end face of the outer shell 1. The front end face of the two arc-shaped frames 301 is fixedly connected to the mounting bracket 302. The two mounting brackets 302 are rotatably connected to each other. Flexible magnets 304 are fixedly connected to the front end face of the outer shell 1 at the upper end of the two arc-shaped frames 301.

[0021] like Figure 1 , 2 As shown in Figures 3, 4, and 6, the sprinkler structure 2 includes a storage tank 201. A lifting cover 202 is slidably connected to the upper part of the storage tank 201. Grooves 213 are provided on the lower part of the outer side wall of the lifting cover 202 and the lower part of the inner side wall of the storage tank 201. Rubber connecting rings 214 are provided inside the two grooves 213. The two ends of the rubber connecting rings 214 are fixedly connected to the lower part of the inner side wall of the inner groove 213 and the upper part of the inner side wall of the outer groove 213, respectively.

[0022] A miniature water pump 211 is fixedly connected to the center of the lower inner wall of the storage tank 201. The output end of the miniature water pump 211 passes through the front inner wall of the storage tank 201 and extends to the front end of the storage tank 201. A water pipe 212 is fixedly connected to the end of the water pipe 212. A spray pipe 204 is fixedly connected to the output end of the water pipe 212. Multiple spray holes 208 are arranged horizontally on the lower end face of the spray pipe 204. A metal shaping tube 203 is fixedly connected to the outer wall of the water pipe 212. The miniature water pump 211 draws water from the bottom of the storage tank 201. Water is delivered to the spray nozzle 204 via the water pipe 212 and atomized and sprayed out through the spray holes 208. The metal shaping tube 203 wraps around the water pipe 212. Users can adjust the spray angle and position of the spray nozzle 204 by bending the metal shaping tube 203. The setting of the metal shaping tube 203 makes the spray angle freely adjustable, which can specifically wet stubborn stains. At the same time, it avoids the disadvantage of traditional rigid water pipes 212 that cannot be changed direction, thus improving the flexibility and coverage of cleaning.

[0023] A water inlet 209 is fixedly connected to the center of the upper end face of the lifting cover 202. A threaded cap 210 is threaded on the upper part of the outer wall of the water inlet 209. A drain valve 205 is fixedly connected to the lower part of one side of the rear end face of the storage tank 201. The cleaning fluid is injected into the storage tank 201 through the water inlet 209. The threaded cap 210 is tightened to achieve a seal. When the equipment is idle or the cleaning fluid needs to be replaced, the drain valve 205 is opened, and the residual liquid in the tank is discharged by gravity. The addition of the drain valve 205 solves the problem of residual water inside the equipment deteriorating or freezing when the equipment is stored, effectively prevents bacterial growth, extends the service life of the micro water pump 211, and improves the hygiene standard of the equipment.

[0024] The storage box 201 has buckles 206 fixedly connected to the upper center of both sides of the storage box 201. Hooks 207 are fixedly connected to the upper center of both sides of the lifting cover 202 located above the two buckles 206. The cooperation between the buckles 206 and the hooks 207 ensures that the structure is stable when stored and prevents the lifting cover 202 from shaking when carried.

[0025] like Figure 1 , 2As shown in Figures 3 and 5, taking one of the drive structures 4 as an example, the drive structure 4 includes multiple drive wheels 401. The multiple drive wheels 401 are arranged in a front-to-back arrangement and rotatably connected to the lower side wall of one side of the outer shell 1. A micro servo geared motor 404 is fixedly connected to the side wall of the outer shell 1 on the side of the rear drive wheel 401. The output end of the micro servo geared motor 404 is fixedly connected to the rear drive wheel 401. A drive belt 402 is sleeved on the outer wall of the multiple drive wheels 401. A protective cover 403 is fixedly connected to the side wall of the outer shell 1 above the drive belt 402. The micro servo geared motor 404 outputs power to drive the drive wheel 401 to rotate. The power is synchronously transmitted to the other drive wheels 401 through the drive belt 402 to achieve multi-wheel synchronous drive. The protective cover 403 covers the drive belt 402, isolating external dust and foreign objects, increasing the contact area and friction with the glass surface, and improving obstacle crossing ability and climbing stability.

[0026] like Figure 3 , 4 As shown in Figure 7, the adsorption structure 5 includes a mounting plate 501. A frame 503 is fixedly sleeved on the outer wall of the mounting plate 501. A storage groove 504 is opened at the center of the lower end face of the frame 503. A rubber seat 505 is fixedly connected inside the storage groove 504. Two negative pressure grooves 506 are concentrically opened near the edge of the lower end face of the rubber seat 505. Negative pressure components 502 are provided on the upper end face of the two negative pressure grooves 506 and the mounting plate 501. Four hard magnets 305 are fixedly connected in a rectangular arrangement on the lower end face of the mounting plate 501. Rubber pads 306 are fixedly connected on the lower end face of the four hard magnets 305. The three negative pressure components 502 are responsible for drawing out the air inside the two negative pressure grooves 506 and the rubber seat 505 to form a negative pressure, increasing the adsorption force. The multi-layer arrangement reduces the risk of air leakage and falling.

[0027] Taking one of the negative pressure components 502 as an example, the negative pressure component 502 includes a miniature air pump 5021. The input end of the miniature air pump 5021 is fixedly connected to a pressure holding valve 5022. The input end of the pressure holding valve 5022 is fixedly connected to a connecting pipe 5023. When the miniature air pump 5021 draws air, the airflow pushes open the pressure holding valve 5022 to form a passage. When the equipment is powered off or the air pump stops working, the pressure holding valve 5022 automatically closes under its own weight and external atmospheric pressure, cutting off the passage between the outside world and the negative pressure tank 506. The pressure holding valve 5022 realizes the power failure self-locking function. In the event of an accidental power failure or equipment failure that causes a shutdown, it can instantly lock the negative pressure to prevent the equipment from falling due to loss of power, which greatly ensures the safety of high-altitude operations.

[0028] A partition 7 is fixedly connected to the center of the inner shell 1. A battery module 8 is fixedly connected to the upper surface of the partition 7. An integrated control chip 6 is fixedly connected to the center of the upper surface of the battery module 8. The integrated control chip 6 serves as the core processing unit, receiving sensor signals and controlling the power distribution of the battery module 8. It also coordinates the start, stop, and speed of the micro servo geared motor 404, the micro air pump 5021, and the micro water pump 211. By integrating the battery module 8 and the integrated control chip 6 onto the partition 7, the internal space layout of the machine body is optimized, and the electrical components are highly centralized and modularized. This helps to lower the center of gravity of the machine body and improve walking stability.

[0029] Example 2: The difference between this embodiment and Embodiment 1 is that the adsorption structure 5 and the cleaning structure 3 have been improved in this embodiment as follows: In addition to the double negative pressure grooves 506, the biomimetic micro-adsorption unit also has several truncated cone-shaped micro-suction cups arranged in an array on the lower end face of the rubber seat 505. The height of the truncated cone-shaped micro-suction cups is 0.2mm higher than the bottom surface of the rubber seat 505.

[0030] An inertial pendulum mechanism is provided above the partition 7, with an inertial pendulum 9 added. The pendulum is hinged inside the outer casing 1 by a torsion spring.

[0031] A piezoelectric film layer is provided in the gap between the storage box 201 and the partition 7. The film is electrically connected to the battery module 8.

[0032] When the device starts adsorption, the micro air pump 5021 draws air, which not only creates an annular negative pressure, but also draws out the air in the truncated cone-shaped micro suction cup, producing a strong local adsorption effect. When the robot walks to the window frame or an area with old glue marks that causes the main seal to leak, the micro suction cup 507 can provide micro-grabbing force like a gecko's foot to prevent it from falling instantly.

[0033] During the robot's movement, the vibrations generated by the body cause the inertial pendulum to swing back and forth, impacting and pressing the piezoelectric film below, converting mechanical energy into electrical energy and storing it in the battery module 8, thus realizing micro-energy recovery during the movement.

[0034] When the equipment experiences a sudden power outage, in addition to the pressure holding valve 5022 closing, the battery module 8 uses the recovered electrical energy to drive the micro air pump 5021 to intermittently replenish air and maintain the pressure balance in the negative pressure tank 506.

[0035] By incorporating a truncated cone-shaped micro-suction cup 507, the risk of the ultra-thin robot falling due to instantaneous air leakage from the main sealing ring when crossing window frames or uneven surfaces is resolved. This achieves a double guarantee of macroscopic sealing failure and microscopic adsorption as a backup. Utilizing a kinetic energy recovery system composed of an inertial pendulum and a piezoelectric film, the robot's endurance during high-altitude operations is effectively extended without increasing battery volume. It is particularly suitable for cleaning large areas of glass. The micro-suction cup array increases the peeling force between the robot body and the glass, effectively suppressing warping and deformation of the robot body edges when facing strong side winds at high altitudes.

[0036] Working principle: In use, by rotating the arc-shaped frames 301 at both ends outward, the arc-shaped frames 301 drive the two cleaning brushes 303 to rotate. The four arc-shaped frames 301 detach from the adsorption of the four hard magnets 305. After rotating 180 degrees, the four arc-shaped frames 301 are adsorbed by the four flexible magnets 304, unfolding the device. Then, by removing the hanging rods on the two buckles 206 from the two hooks 207, the lifting cover 202 is pulled upward. The lifting cover 202 drives the rubber connecting ring 214 to move upward. Then, the threaded cover 210 is rotated in the opposite direction to remove it. Water is added to the storage tank 201 and the lifting cover 202 through the water inlet 209. After adding water, the threaded cover 210 is threaded onto the water inlet 209.

[0037] The device is started by the integrated control chip 6, and the battery module 8 supplies power to all electrical components. The micro air pump 5021 works to extract air from the two negative pressure grooves 506 on the lower end face of the rubber seat 505 through the connecting pipe 5023 and the pressure holding valve 5022 to create negative pressure, allowing the device to adhere to the glass surface through the rubber seat 505. When the power is off, the pressure holding valve 5022 automatically closes to maintain negative pressure and prevent it from falling. The micro servo geared motor 404 starts and drives the rear drive wheel 401 to rotate. The drive belt 402 drives multiple drive wheels 401 to rotate synchronously. The protective cover 403 protects the internal components of the drive structure 4, enabling the entire device to move on the glass surface. During the movement, the cleaning brush 303 of the front cleaning structure 3 moves along the two... The mounting bracket 302 rotates to scrub the stains on the glass surface. At the same time, the micro water pump 211 pumps the cleaning liquid in the storage tank 201 into the spray pipe 204 through the water pipe 212. The liquid is then sprayed onto the glass surface through multiple spray holes 208. The metal shaping tube 203 can adjust the spray angle of the spray pipe 204. The drain valve 205 is used to drain the remaining liquid. The front soft brush 303 and the rear silicone squeegee brush 303 simultaneously scrape the cleaned glass surface dry. A multi-port pipe is set at the input end of the micro water pump 211. The input ends of this multi-port pipe are distributed in various positions on the lower inner wall of the storage tank 201 to ensure that the storage tank 201 can draw in cleaning water at different angles and even when the water level is not full.

[0038] The integrated control chip 6 controls the micro servo geared motor 404 to drive the drive wheel 401 and drive belt 402 to move along a preset path. Infrared edge sensors located at the four corners of the outer casing 1 monitor the distance between the machine body and the glass boundary in real time. When the sensor detects a sudden change in distance exceeding a threshold and determines that the glass edge has been reached, the integrated control chip 6 immediately controls the micro servo geared motors 404 on both sides to output reverse torque, causing the drive wheel 401 and drive belt 402 to reverse differentially, automatically changing the direction of the machine body and adjusting its trajectory to continue cleaning. When the integrated control chip 6 moves according to the preset path... Once the cleaning area or time is determined and cleaning is completed, the micro air pump 5021 stops working. At the same time, the pressure holding valve 5022 automatically closes under the residual negative pressure in the negative pressure tank 506 to form a physical lock, maintaining the negative pressure state in the negative pressure tank 506 at a level not lower than 80% of the initial value. The micro servo reduction motor 404 is de-energized and stops driving. The drive wheel 401 and drive belt 402 are locked, the cleaning brush 303 stops rotating, and the equipment remains stably on the glass surface by the adsorption force of the rubber seat 505, the hard magnet 305, and the rubber pad 306, waiting for the user to manually remove it.

[0039] When storing, rotate the four arc-shaped brackets 301 to separate them from the flexible magnets 304. Rotate them to the bottom of the mounting plate 501, where the four arc-shaped brackets 301 are attracted by the four rigid magnets 305. The rubber pads 306 reduce the impact of impacts. Then, drain the remaining water inside the storage box 201 through the drain valve 205. Press down on the lifting cover 202 and lock it by hanging the hanging rods on the two buckles 206 onto the two hooks 207. After storage, the volume is reduced, making it easy to carry.
