Description

Technical Field

[0001] This utility model relates to the field of autonomous cleaning robot technology, specifically an autonomous cleaning robot with quick-release cleaning components. Background Technology

[0002] Autonomous cleaning robots are intelligent devices that integrate artificial intelligence, sensor technology, navigation algorithms, and mechanical structures. They can automatically complete cleaning tasks without human intervention. Their core advantage lies in their ability to achieve efficient cleaning by autonomously planning paths, avoiding obstacles, and identifying cleaning areas, thus replacing manual labor.

[0003] Taking a duct cleaning robot as an example, it is an intelligent device specifically designed for cleaning the inside of ventilation ducts. Through a preset cleaning program, the robot autonomously travels along the duct. During the journey, it scrapes away stubborn dust from the inner wall of the duct using rotating cleaning components. When the cleaning components (such as nylon brushes) are worn due to long-term use, entangled with fibrous debris, or stuck by hard objects, the robot needs to be stopped and replaced. Generally, the cleaning components and the rotating shaft are fixedly connected by screws, and disassembly requires special tools. The replacement process is relatively complicated and reduces cleaning efficiency. Therefore, an autonomous cleaning robot with quick-release cleaning components is needed. Utility Model Content

[0004] The purpose of this invention is to provide an autonomous cleaning robot with quick-release cleaning components to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an autonomous cleaning robot with quick-release cleaning components, comprising a robot body, a main cleaning brush, a rotating shaft, and a secondary cleaning brush. A fixed cylinder is mounted on one end of the top of the robot body via a rotating seat, and a lifting sleeve is installed inside the fixed cylinder. A drive box is mounted on one end of the lifting sleeve, and the main cleaning brush and secondary cleaning brush are respectively mounted on one end and both sides of the drive box via the rotating shaft. An mounting sleeve is mounted on the end of each of the main and secondary cleaning brushes near the rotating shaft, and the end of each rotating shaft near the mounting sleeve is connected to the mounting sleeve via an insert block. An adsorption head is mounted on one end of each insert block, and a permanent magnet is installed inside each adsorption head. An adsorption layer is provided on the inner wall of each mounting sleeve, and buckles are mounted on both sides of the inner side of the mounting sleeve via spring posts.

[0006] Preferably, a cylinder is installed inside the top surface of the robot body via a rotating frame, and the output end of the cylinder is rotatably connected to the fixed cylinder via a telescopic rod.

[0007] Preferably, a lead screw is provided at the center of the inside of the fixed cylinder, and the lifting sleeve is threadedly connected to the lead screw.

[0008] Preferably, a micro motor is fixed at one end inside the fixed cylinder, and the output end of the micro motor is connected to the lead screw.

[0009] Preferably, a first bevel gear is provided at the center of the drive box, a drive motor is fixed on one side of the lifting sleeve, and the output end of the drive motor is connected to the first bevel gear through a drive shaft.

[0010] Preferably, the first bevel gear is meshed with a second bevel gear on both sides, and both the first bevel gear and the second bevel gear are connected to the rotating shaft.

[0011] Preferably, each of the buckles has a hook at one end near the insertion block, and each of the insertion blocks has a hook groove at one end near the hook that matches the hook.

[0012] Preferably, each of the buckles is provided with a guide wheel on one side, and the guide wheel slides along a pre-set guide groove inside the mounting sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This autonomous cleaning robot with quick-release cleaning components consists of a robot body, a fixed cylinder, a lifting sleeve, a drive box, a drive motor, a rotating shaft, a main cleaning brush, a secondary cleaning brush, a mounting sleeve, a plug, a suction head, a permanent magnet, a suction layer, buckles, and spring posts. One end of both the main and secondary cleaning brushes is connected to the plug on the rotating shaft via the mounting sleeve. The plug is inserted into the mounting sleeve and applies pressure to the buckles on both sides, causing them to squeeze the spring post on one side to create clearance space until the suction head at one end of the plug is engaged. The attachment head magnetically engages with the adsorption layer. At this point, the buckle moves to one side of the insertion block under the reset action of the spring column. The hook of the buckle engages with the pre-set hook groove on the insertion block. During installation, simply align the insertion block with the mounting sleeve and insert it. The inclined surface of the insertion block pushes the buckle to compress the spring column until the adsorption head engages with the adsorption layer. The buckle automatically engages with the hook groove, eliminating the need for screwdrivers, wrenches, or other tools. This improves efficiency compared to traditional screw fixing and meets the need for quick on-site replacement. By replacing the main cleaning brush or auxiliary cleaning brush of different specifications, the robot body can adapt to duct cleaning in different environments. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 The present invention provides an embodiment of an autonomous cleaning robot with quick-release cleaning components, comprising a robot body 1, a main cleaning brush 7, a rotating shaft 13 and a secondary cleaning brush 23. A fixed cylinder 3 is provided at one end of the top of the robot body 1 via a rotating seat 2, and a lifting sleeve 5 is provided inside the fixed cylinder 3. A drive box 6 is provided at one end of the lifting sleeve 5, and the main cleaning brush 7 and the secondary cleaning brush 23 are respectively provided at one end and both sides of the drive box 6 via the rotating shaft 13.

[0023] Both the main cleaning brush 7 and the auxiliary cleaning brush 23 are provided with a mounting sleeve 11 at one end near the rotating shaft 13, and the end of the rotating shaft 13 near the mounting sleeve 11 is connected to the mounting sleeve 11 through the insert block 12.

[0024] Each of the insert blocks 12 is provided with an adsorption head 14 at one end, and the two sides inside the mounting sleeve 11 are provided with buckles 17 through spring posts 18.

[0025] Align the mounting sleeve 11 on the main cleaning brush 7 or the auxiliary cleaning brush 23 with the insert block 12 on the rotating shaft 13 and insert it. The inclined surface of the insert block 12 presses against the buckles 17 on both sides inside the mounting sleeve 11, so that the buckles 17 compress the spring column 18 to form a clearance space. Then the spring column 18 resets and pushes the buckles 17, and the hook part 16 of the buckles 17 engages with the hook groove of the insert block 12 to complete the mechanical locking.

[0026] The interior of each adsorption head 14 is provided with a permanent magnet 20, and the inner wall of each mounting sleeve 11 is provided with an adsorption layer 15. When the adsorption head 14 at the end of the insertion block 12 approaches the adsorption layer 15, the permanent magnet 20 inside the adsorption head 14 and the adsorption layer 15 magnetically attract each other to achieve a tight adsorption.

[0027] When installing the main cleaning brush 7 and the auxiliary cleaning brush 23, simply align the insert 12 with the mounting sleeve 11 and insert it. The inclined surface of the insert 12 pushes the buckle 17 to compress the spring column 18 until the suction head 14 and the suction layer 15 are attracted together. The buckle 17 automatically snaps into the hook groove, without the need for screwdrivers, wrenches or other tools.

[0028] Each side of the buckle 17 is provided with a guide wheel 19, and the guide wheel 19 slides along the pre-set guide groove in the mounting sleeve 11, so that the buckle 17 maintains a straight movement trajectory when it is pressed or reset, and avoids failure of engagement due to deviation.

[0029] A cylinder 4 is installed inside the top surface of the robot body 1 via a rotating frame, and the output end of the cylinder 4 is rotatably connected to the fixed cylinder 3 via a telescopic rod.

[0030] The fixed cylinder 3 can be flexibly adjusted to multiple angles under the drive of the cylinder 4, and can quickly adapt to different duct environments with different tilt angles and bending shapes;

[0031] A lead screw 9 is provided at the center of the inside of the fixed cylinder 3, and the lifting sleeve 5 is threadedly connected to the lead screw 9;

[0032] A micro motor 8 is fixed at one end inside the fixed cylinder 3, and the output end of the micro motor 8 is connected to the lead screw 9;

[0033] By utilizing the helical transmission characteristics of the lead screw 9, the lifting sleeve 5 can achieve stable and precise up and down displacement. When the robot body 1 enters air ducts of different diameters, the height of the drive box 6, the main cleaning brush 7, and the auxiliary cleaning brush 23 can be adjusted as needed to avoid collision with the pipe wall or affecting the cleaning effect due to excessive distance.

[0034] A first bevel gear 21 is provided in the center of the drive box 6, and a drive motor 10 is fixed on one side of the lifting sleeve 5. The output end of the drive motor 10 is connected to the first bevel gear 21 through the drive shaft.

[0035] Both sides of the first bevel gear 21 are meshed with the second bevel gear 22, and both the first bevel gear 21 and the second bevel gear 22 are connected to the rotating shaft 13.

[0036] The drive motor 10 drives the first bevel gear 21 in the drive box 6 to rotate through the drive shaft. The first bevel gear 21 meshes with the second bevel gears 22 on both sides, thereby causing the rotating shaft 13 to rotate and drive the main cleaning brush 7 and the auxiliary cleaning brush 23 to rotate at high speed.

[0037] It can simultaneously drive the main cleaning brush 7 and the auxiliary cleaning brush 23 to rotate in opposite directions at the same speed, forming a highly efficient cleaning force, which greatly improves cleaning efficiency compared to single cleaning brush operation.

[0038] Then, the robot body 1 travels along the air duct that needs to be cleaned through a preset cleaning program. During the travel, the rotating main cleaning brush 7 and the auxiliary cleaning brush 23 scrape away the stubborn dust on the inner wall of the duct. The dust is sucked away in real time by the built-in high-pressure vacuum fan of the robot body 1 through the hose connected to the external dust collection box, thus avoiding secondary pollution (this is the existing technology).

[0039] When the cleaning parts need to be disassembled, the mounting sleeve 11 is pulled to one side, the buckle 17 overcomes the elastic force of the spring column 18, and the hook part 16 of the buckle 17 is disengaged from the hook groove of the insert block 12, so that the main cleaning brush 7 and the auxiliary cleaning brush 23 can be manually pulled out. At the same time, the magnetic attraction is released, which improves efficiency compared with traditional screw fixing and meets the needs of quick on-site replacement.

[0040] The specific models and specifications of the drive motor 10, the micro motor 8, and the cylinder 4 need to be determined by selection calculation based on the specifications and parameters of the device. The selection calculation method is existing technology, so it will not be described in detail here.

[0041] Working principle: In this embodiment, when in use, the mounting sleeve 11 on the main cleaning brush 7 or the auxiliary cleaning brush 23 is aligned with the insert block 12 on the rotating shaft 13 and inserted. The inclined surface of the insert block 12 presses against the buckles 17 on both sides of the mounting sleeve 11, causing the buckles 17 to compress the spring column 18 to form a clearance space. When the suction head 14 at the end of the insert block 12 approaches the suction layer 15, the permanent magnet 20 inside the suction head 14 magnetically attracts the suction layer 15 to achieve a tight attraction. Subsequently, the spring column 18 resets and pushes the buckles 17, and the hook 16 of the buckles 17 engages with the hook groove of the insert block 12 to complete the mechanical locking. After the robot body 1 starts, the cylinder 4 in the rotating frame on the top surface pushes the fixed cylinder 3 to adjust the angle around the rotating seat 2 through the telescopic rod. At the same time, the micro motor 8 in the fixed cylinder 3 drives the lead screw 9 to rotate, causing the lifting sleeve 5 threaded with it to move up and down, thereby adjusting the drive box 6 to a suitable cleaning height. The drive motor 10 on one side of the lifting sleeve 5... The drive shaft drives the first bevel gear 21 inside the drive box 6 to rotate. The first bevel gear 21 meshes with the second bevel gears 22 on both sides, which in turn causes the rotating shaft 13 to rotate, driving the main cleaning brush 7 and the auxiliary cleaning brush 23 to rotate at high speed. The robot body 1 travels along the air duct that needs to be cleaned according to the preset cleaning program. During the travel, the rotating main cleaning brush 7 and the auxiliary cleaning brush 23 scrape away the stubborn dust accumulated on the inner wall of the duct. The dust is sucked away in real time by the high-pressure vacuum fan built into the robot body 1 through the hose connected to the external dust collection box, avoiding secondary pollution (this is the existing technology). When it is necessary to disassemble the cleaning parts, the mounting sleeve 11 is pulled to one side, and the buckle 17 overcomes the elasticity of the spring column 18, so that the hook part 16 of the buckle 17 disengages from the hook groove of the insert block 12, and the main cleaning brush 7 and the auxiliary cleaning brush 23 can be manually pulled out. At the same time, the magnetic attraction is released. Compared with the traditional screw fixing, the efficiency is improved, which meets the needs of quick replacement on site.
