[0040] The embodiment of the present invention provides a cleaning robot that integrates floor, wall and ceiling cleaning functions, has a wide range of uses, and meets users' needs for whole-house cleaning.

[0041] The following combination Figure 1-Figure 4 The technical solution provided by the present invention is described in more detail.

[0042] See also Figure 1-Figure 4 As shown, the cleaning robot provided by the present invention integrates floor, wall and ceiling cleaning, including a floor cleaning body 1, a lifting push rod 2 and a rotating cleaning brush head assembly, wherein: the floor cleaning body 1 is movably arranged, the lifting push rod 2 is detachably fixed to the floor cleaning body 1, the rotating cleaning brush head assembly is rotatably connected to the upper part of the lifting push rod 2, and the lifting push rod 2 is used to lift the rotating cleaning brush head assembly to different heights; more than two cleaning heads are provided on the rotating cleaning brush head assembly, and the cleaning heads are used to handle stains in different forms; the rotating cleaning brush head assembly is rotatably arranged, so that different cleaning heads can be rotated to the part to be cleaned.

[0043] For details, see Figure 1-Figure 4 As shown, the rotary cleaning brush head assembly of this embodiment includes any one or more of a cleaning nozzle 3, a dust collecting head 4 and a wiping cleaning part 5; the cleaning nozzle 3 is connected to the water tank through a steam pipeline, and the dust collecting head 4 is connected to the negative pressure device through an air pipe, and the water tank and the negative pressure device are located inside or outside the floor cleaning body 1; the rotary cleaning brush head assembly is rotatably arranged to rotate the cleaning nozzle 3 or the dust collecting head 4 or the wiping cleaning part 5 to the part to be cleaned.

[0044] Among them, the floor cleaning body 1 can be a floor cleaning robot in the existing technology. As an existing mature technology, the floor cleaning body 1 is equipped with a variety of sensors such as three-dimensional sensors, AI visual cameras, infrared sensors, optical sensors, etc. to achieve comprehensive perception of the surrounding environment and data collection. Combining the environmental data obtained by the three-dimensional sensor and the AI vision algorithm, the path planning algorithm and obstacle avoidance algorithm are used to realize the robot's autonomous navigation and automatic obstacle avoidance. The navigation and obstacle avoidance algorithm can dynamically adjust the robot's driving path according to real-time environmental data to ensure that the cleaning task is completed safely and efficiently. A high-energy-density lithium battery is used as the power source, in conjunction with the motor and the walking wheel 11, to realize the movement of the robot and the drive of the cleaning mechanism. The walking wheel 11 adopts an anti-slip design to ensure that the robot can travel stably on different ground materials. I will not go into details here.

[0045] The floor cleaning body 1 is cylindrical, which is convenient for flexible movement in a narrow space.

[0046] The water tank can be located inside or outside the housing of the floor cleaning body 1. It is connected to the cleaning nozzle 3 via a steam line. A heater is provided inside the water tank to heat the water therein. The heater can be a heating rod or other conventional structure. Steam ejected from the cleaning nozzle 3 can enhance the cleaning effect. Alternatively, alcohol solvents or other cleaning agents can be added to the water tank to enhance the cleaning effect.

[0047] The steam pipeline can be provided with a retractable pipeline such as a bellows, which does not affect the retraction of the lifting push rod 2.

[0048] Similarly, the air pipe connecting the dust collecting head 4 and the negative pressure device can also be a telescopic tube such as a bellows, which does not affect the telescopic movement of the lifting push rod 2. The negative pressure device can be the original negative pressure device in the floor cleaning body 1.

[0049] The cleaning robot of this embodiment adopts negative pressure adsorption in conjunction with the lifting push rod 2. The robot uses its own vacuum pump to form a negative pressure environment when it is close to the wall or ceiling, generating a strong adsorption force to ensure that the body is stably attached to the vertical surface.

[0050] This embodiment of the cleaning robot integrates floor, wall, and ceiling cleaning. The floor cleaning body 1 moves to clean the floor. When the lifting push rod 2 retracts, the rotating cleaning brush head assembly can rotate to move the cleaning nozzle 3, the dust collection head 4, or the wiping cleaning part 5 to the area to be cleaned on the wall. Cleaning is performed by spraying high-temperature steam, vacuuming, or wiping, thereby improving the cleaning effect. When the ceiling needs to be cleaned, the floor cleaning body 1 moves below the ceiling to be cleaned, the lifting push rod 2 extends, and the rotating cleaning brush head assembly cleans the area to be cleaned on the ceiling. This cleaning robot integrates wall, ceiling, and floor cleaning functions and has a wide range of uses, meeting users' needs for whole-house cleaning.

[0051] As an alternative embodiment, see Figure 1-Figure 3 As shown, the rotary cleaning brush head assembly also includes a bracket 6 and a rotary drive device 7. The cleaning nozzle 3, the dust collection head 4 and the wiping cleaning part 5 are arranged at intervals around the axis of the bracket 6; the bracket 6 is rotatably connected to the upper end of the lifting push rod 2, and the rotary drive device 7 is driven and connected to the bracket 6 to drive the bracket 6 to rotate 360°.

[0052] The rotating drive device 7 can be a motor, etc. The rotating drive device 7 drives the bracket 6 to rotate 360°, which is convenient for quickly rotating the cleaning nozzle 3, the dust collection head 4 or the wiping cleaning part 5 to the part to be cleaned. According to the situation of the part to be cleaned, the cleaning nozzle 3, the dust collection head 4 or the wiping cleaning part 5 can be selectively used for cleaning, thereby improving the cleaning effect.

[0053] As an optional embodiment, the cleaning robot also includes an identification unit, an angle sensor and a controller, wherein: the identification unit is used to identify stains at the area to be cleaned; the angle sensor is used to detect the angle of the rotating cleaning brush head assembly; the controller is electrically connected to the identification unit, the angle sensor, and the rotation drive device, and is used to control the rotation angle of the rotating cleaning brush head assembly according to the type of stains, so that the corresponding cleaning head rotates to the area to be cleaned.

[0054] Specifically, the recognition unit can be a camera, etc., which can control the corresponding cleaning head to rotate to the part to be cleaned by identifying the stains and the form of the stains on the part to be cleaned. For example, when the recognition unit recognizes dust on the wall, the controller determines the position of the corresponding cleaning part 5 based on the information from the angle sensor, and can rotate the wiping cleaning part 5 to the part to be cleaned on the wall to wipe off the dust. When the recognition unit recognizes oil stains on the wall, the controller can similarly rotate the cleaning nozzle 3 to the part to be cleaned, and use the high-temperature steam or water with detergent sprayed from the cleaning nozzle 3 to spray and flush the oil stains, further improving the cleaning effect.

[0055] As an alternative embodiment, see Figure 1 As shown, the cleaning nozzle 3 includes a base 31, a conical portion 32 and a nozzle 33, wherein: the conical portion 32 is fixed on the base 31, the conical portion 32 is connected to the water tank through a steam pipeline, the inner diameter of the conical portion 32 gradually decreases in the direction away from the base 31, and the nozzle 33 is connected to the narrow end of the conical portion 32.

[0056] When the water in the water tank enters the conical portion 32 through the steam pipeline, the inner diameter of the conical portion 32 gradually decreases in the direction away from the seat body 31, and the fluid is gradually added. High-speed fluid is ejected from the nozzle 33 to impact the area to be cleaned. The use of high-pressure airflow or water flow can improve the cleaning effect.

[0057] As an alternative embodiment, see Figure 1 As shown, the cleaning nozzle 3 further includes a scraper 34 and a connecting rod 35, wherein the scraper 34 is fixed to the side of the nozzle 33 away from the base 31 through the connecting rod 35, and the scraper 34 is arranged opposite to the nozzle 33 with a distance between them.

[0058] Specifically, the number of connecting rods 35 is two or more, and the connecting rods 35 are arc-shaped rods. The two arc-shaped connecting rods 35 are symmetrically arranged about the central axis of the cone 32. The horizontal distance between the two connecting rods 35 gradually increases in the direction approaching the scraper 34, which can improve the fixing effect of the scraper 34. The distance between the scraper 34 and the nozzle 33 makes way for the cone 32 and the nozzle 33 to prevent affecting the spraying of air or water.

[0059] The scraper 34 can be a silicone plate, a rubber plate, etc., which is driven to rotate by the rotary drive device 7 and the ground cleaning body 1 moves back and forth a small distance, so that the scraper 34 can continuously scrape the position to be cleaned back and forth, thereby improving the cleaning effect.

[0060] As an alternative embodiment, see Figure 1-Figure 3 As shown, the dust collector head 4 is in a flared shape. The flared dust collector head 4 can increase the adsorption area and improve the cleaning efficiency.

[0061] As an alternative embodiment, see Figure 1 As shown, the wiping and cleaning part 5 includes a mounting seat 51, a rag 52 and a driving device, wherein: the driving device is fixed on the bracket 6, the mounting seat 51 is rotatably connected to the bracket 6, the driving device is driven and connected to the mounting seat 51, and is used to drive the mounting seat 51 to rotate; the mounting seat 51 is trumpet-shaped, and the rag 52 is fixedly laid on the mounting seat 51.

[0062] The driving device can be a motor, which is connected to the shaft on the mounting base 51 through a coupling, thereby driving the mounting base 51 to rotate 360° around its own axis. The mounting base 51 drives the rag 52 to rotate, thereby achieving reciprocating wiping of the cleaning position and improving the cleaning effect.

[0063] As an alternative embodiment, see Figure 2 、 Figure 3 As shown, the lifting push rod 2 of this embodiment includes a multi-stage electric push rod, the bottom end of the multi-stage electric push rod is fixed on the floor cleaning body 1, the multi-stage electric push rod is vertically arranged, and its telescopic end is fixedly connected to the rotating cleaning brush head assembly.

[0064] A multi-stage electric push rod (also known as a multi-stage electric cylinder or telescopic electric push rod) is a linear actuator that achieves multi-stage synchronous extension and retraction through a motor drive. Its core advantage lies in its large travel range, high precision, and compact storage. The lifting push rod 2 of this embodiment uses a multi-stage electric push rod. By extending the multi-stage electric push rod, the rotating cleaning brush head assembly can be pushed to the ceiling position. Or, when cleaning the floor, the multi-stage electric push rod retracts to prevent interference with external obstacles.

[0065] As an optional implementation, the cleaning robot of this embodiment also includes a height sensor and a controller, wherein: the height sensor is fixed to the top end of the lifting push rod 2, and the controller is electrically connected to the height sensor and the lifting push rod 2, and is used to control the extension and retraction direction, speed and stroke of the lifting push rod 2 according to the information of the height sensor.

[0066] The cleaning robot of this embodiment detects the height of the top of the lifting push rod 2 through a height sensor, that is, detects whether the height of the rotating cleaning brush head assembly meets the target requirement. The controller controls the extension and retraction direction, speed and stroke of the lifting push rod 2 (multi-stage electric push rod) according to the information of the height sensor, thereby achieving cleaning at different height positions and being easy to use.

[0067] As an alternative embodiment, see Figure 4 As shown, a walking wheel 11, a guide wheel 12 and a cleaning brush 13 are installed at the bottom of the floor cleaning body 1, and a dust collection box is provided inside the floor cleaning body 1.

[0068] The running wheels 11 can be driven by a motor or the like, which is a prior art and will not be described in detail herein. The floor cleaning body 1 can be a floor cleaning robot in the prior art, which is used to vacuum and clean the floor.

[0069] The cleaning robot in this embodiment, which integrates floor, wall and ceiling cleaning, can perform the following tasks:

[0070] For floor cleaning (the structure and functions of existing floor cleaning robots), the robot can build a real-time map of the home environment and plan the optimal cleaning path based on the map information to ensure that stubborn stains and deep dust are thoroughly removed; it is equipped with a soft and highly absorbent microfiber mop, which can be used to wipe the floor by walking.

[0071] Wall cleaning: The robot can clean wall stains in a planned manner from top to bottom through the lifting push rod 2, and the vacuum head 4 on the robot's rotating cleaning brush head assembly can suck away wall dust.

[0072] Ceiling cleaning: The robot can be extended to the ceiling height through the lifting push rod 2, and the bottom running wheel 11 can be used to adjust the position to clean the ceiling dirt. As with the wall cleaning mode, different cleaning tools can be used for cleaning.

[0073] Bathroom glass, tiles, and kitchen wall cleaning: For smooth surfaces, soapy water, kitchen oil stains and other stains on bathroom glass can be softened by spraying high-temperature steam from the cleaning nozzle 3 and spraying cleaning liquid. The stains can then be scraped off with the scraper 34, and then the rotating rag 52 can be wiped with moderate force and a reasonable rotation speed to ensure the cleaning effect.
