Description

Technical Field

[0001] This utility model relates to the field of unmanned sweeping machine technology, and in particular to a detachable sweeping device for unmanned sweeping machines. Background Technology

[0002] Unmanned sweeping robots, also known as automatic sweeping robots, are intelligent devices that can autonomously clean floors. They are used in small offices, shops, cafes, etc., for daily floor cleaning and maintenance, keeping the business environment clean and hygienic, and improving the overall image of the place. They generally use plastic or metal shells to protect the internal components and also form the main appearance of the sweeping robot. The design takes into account aesthetics and ergonomics, making it easy to operate and place.

[0003] The cleaning mechanism of most unmanned sweeping machines on the market is in close contact with the ground. Therefore, when disassembling the cleaning mechanism, the entire device needs to be lifted or tilted to remove it. The disassembly process is time-consuming and labor-intensive, and it is easy to damage the surface of the device, reducing its practicality. Utility Model Content

[0004] In view of this, the present invention provides a detachable cleaning device for unmanned sweeping machines. The main technical problem to be solved is that the process of disassembling the cleaning mechanism is time-consuming and labor-intensive, and it is also easy to damage the surface of the device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a detachable cleaning device for an unmanned sweeping machine, including a protective mechanism. The protective mechanism includes a housing, and a lifting mechanism is installed on the inner wall of the housing. The lifting mechanism includes a cylinder, the main body of which is fixedly connected to the inner wall of the housing. A connecting plate is fixedly connected to the telescopic end of the cylinder. A second rotating shaft is movably connected inside the connecting plate. A cleaning mechanism is installed on the inner wall of the second rotating shaft. The cleaning mechanism includes a third rotating shaft, the surface of which is in contact with the inner wall of the second rotating shaft. A fourth groove is formed on the surface of the third rotating shaft, and a locking block is fixedly connected to the inner wall of the fourth groove. The locking block is located inside the second rotating shaft, and a rotating brush is fixedly connected to the bottom of the third rotating shaft.

[0006] By adopting the above technical solution, the cylinder retracts and drives the second rotating shaft to rise, applying pressure to the locking block inside the second rotating shaft so that it is pressed down, thereby disengaging the locking block from the second rotating shaft and easily disassembling the cleaning mechanism.

[0007] As a further description of the above technical solution:

[0008] The inner wall of the second rotating shaft is provided with a third groove, and a guide block is fixedly connected to the surface of the third rotating shaft. The guide block is located inside the third groove, and a baffle is fixedly connected to the surface of the second rotating shaft.

[0009] By adopting the above technical solution, the cooperation between the guide block and the third groove makes it easier to align the third rotating shaft during installation.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the outer casing is equipped with a rotating mechanism, which includes a connecting rod. One end of the connecting rod is fixedly connected to the inner wall of the outer casing, and the other end of the connecting rod is fixedly connected to a rotating ring. A first gear is movably connected to the lower surface of the rotating ring.

[0012] By adopting the above technical solution, the height of the first gear is fixed. When the protrusion rises to the set height, the second shaft will no longer rotate. At this time, when the cleaning mechanism is replaced, there is no need to worry about the device failing to shut off in time.

[0013] As a further description of the above technical solution:

[0014] The surface of the second rotating shaft is fixedly connected to a protrusion, which is slidably connected to the inner wall of the first gear and is located above the baffle.

[0015] The second shaft can rotate by adopting the above technical solution because the protrusion fixed on the surface of the second shaft is inserted into the square groove on the inner wall of the first gear.

[0016] As a further description of the above technical solution:

[0017] The upper surface of the outer casing has a first groove and a second groove, with the first groove located to the left of the second groove.

[0018] By adopting the above technical solution, a cleaning box is installed inside the first groove for collecting garbage, and a battery is installed inside the second groove to facilitate the operation of the device.

[0019] As a further description of the above technical solution:

[0020] The inner wall of the housing is equipped with a power mechanism, which includes a motor. The main body of the motor is fixedly connected to the inner wall of the housing. The output end of the motor is fixedly connected to a fourth rotating shaft. A second gear is fixedly connected to the surface of the fourth rotating shaft. The surface of the second gear meshes with the surface of the first gear.

[0021] By adopting the above technical solution, the motor drives the second gear to rotate, and because the second gear meshes with the first gear, it can drive the first gear to rotate.

[0022] As a further description of the above technical solution:

[0023] A moving mechanism is installed on the lower surface of the housing. The moving mechanism includes a support rod. The upper surface of the support rod is fixedly connected to the bottom of the housing. A first rotating shaft is fixedly connected to the surface of the support rod. A first wheel is movably connected to the surface of the first rotating shaft. A second wheel is movably connected to the bottom of the housing.

[0024] By adopting the above technical solution, the first wheel is used to support the front half of the device, and the second wheel is equipped with a motor, enabling it to move forward autonomously.

[0025] By employing the above technical solution, the detachable sweeping device for the unmanned sweeping machine of this utility model has at least the following beneficial effects:

[0026] 1. Compared with existing technologies, this unmanned sweeping robot's detachable cleaning device, through a cylinder, a second rotating shaft, and a locking block, allows for easy disassembly of the cleaning mechanism for replacement or cleaning of hair entangled on its surface. The cylinder retracts, causing the connecting plate to rise. The second rotating shaft is movably connected inside the connecting plate. This connection between the cylinder and the second rotating shaft not only facilitates convenient control of the second rotating shaft's lifting and lowering but also prevents the cylinder's operation from being affected by the rotation of the second rotating shaft. When the second rotating shaft rises, the cleaning mechanism installed inside it... As the height increases, pressure is applied to the locking block inside the second rotating shaft to force it downwards, allowing the locking block to disengage from the second rotating shaft and easily detach the cleaning mechanism. Compared to conventional devices where the cleaning mechanism is in contact with the ground, requiring the entire device to be lifted or tilted to disassemble, which is time-consuming, labor-intensive, and prone to damaging the device's surface, reducing its practicality, this device allows for easy disassembly of the cleaning mechanism, improving its usability.

[0027] 2. Compared with existing technologies, this unmanned sweeping robot's detachable cleaning device, through a second rotating shaft and a protrusion, allows the second rotating shaft to rise during disassembly, i.e., the protrusion fixed to the surface of the second rotating shaft rises. The second rotating shaft can rotate because the protrusion fixed to the surface of the second rotating shaft is inserted into the square groove on the inner wall of the first gear. The height of the first gear in this device is fixed. When the protrusion rises to the set height, the second rotating shaft will no longer rotate. At this time, when replacing the cleaning mechanism, there is no need to worry about the first gear continuing to rotate due to the device not closing in time, causing the second rotating shaft to continue rotating and resulting in injury from the cleaning mechanism during the replacement process, thus improving the safety of the device.

[0035] Reference Figure 1-5The present invention provides a detachable cleaning device for an unmanned sweeping machine, comprising a protective mechanism 1, a housing 101, a lifting mechanism 3 mounted on the inner wall of the housing 101, a cylinder 301, the main body of the cylinder 301 being fixedly connected to the inner wall of the housing 101, a connecting plate 302 being fixedly connected to the telescopic end of the cylinder 301, a second rotating shaft 303 being movably connected inside the connecting plate 302, a cleaning mechanism 4 mounted on the inner wall of the second rotating shaft 303, and a third rotating shaft 401. The surface of the third shaft 401 is in contact with the inner wall of the second shaft 303. A fourth groove 402 is provided on the surface of the third shaft 401. A locking block 403 is fixedly connected to the inner wall of the fourth groove 402. The locking block 403 is located inside the second shaft 303. A rotating brush 405 is fixedly connected to the bottom of the third shaft 401. When the cylinder 301 retracts, it drives the second shaft 303 to rise. Pressure is applied to the locking block 403, which is locked inside the second shaft 303, so that it is pressed down. This allows the locking block 403 to disengage from the second shaft 303, and the cleaning mechanism 4 can be easily disassembled.

[0036] The inner wall of the second rotating shaft 303 has a third groove 305. A guide block 404 is fixedly connected to the surface of the third rotating shaft 401. The guide block 404 is located inside the third groove 305. A baffle 306 is fixedly connected to the surface of the second rotating shaft 303. The cooperation between the guide block 404 and the third groove 305 makes it easier to align the third rotating shaft 401 during installation. A rotating mechanism 5 is installed on the inner wall of the outer casing 101. The rotating mechanism 5 includes a connecting rod 503. One end of the connecting rod 503 is fixedly connected to the inner wall of the outer casing 101, and the other end of the connecting rod 503 is fixedly connected to a rotating ring 502. The lower surface of 502 is movably connected to the first gear 501, which has a fixed height. When the protrusion 304 rises to the set height, the second rotating shaft 303 will no longer rotate. Therefore, when replacing the cleaning mechanism 4, there is no need to worry about the device failing to close in time. The surface of the second rotating shaft 303 is fixedly connected to the protrusion 304, which slides on the inner wall of the first gear 501. The protrusion 304 is located above the baffle 306. The second rotating shaft 303 can rotate because the protrusion 304 fixed on its surface is inserted into the square groove on the inner wall of the first gear 501. The outer casing 101... A first groove 102 is formed on the upper surface of the outer casing 101, and a second groove 103 is formed on the upper surface of the outer casing 101. A cleaning box is installed inside the first groove 102 for collecting garbage, and a battery is installed inside the second groove 103 for convenient operation of the device. The first groove 102 is located to the left of the second groove 103. A power mechanism 6 is installed on the inner wall of the outer casing 101. The power mechanism 6 includes a motor 603. The main body end of the motor 603 is fixedly connected to the inner wall of the outer casing 101. A fourth rotating shaft 602 is fixedly connected to the output end of the motor 603. A second gear 601 is fixedly connected to the surface of the fourth rotating shaft 602. The surface of gear 601 meshes with the surface of the first gear 501. Motor 603 drives the second gear 601 to rotate. Since the second gear 601 meshes with the first gear 501, it can drive the first gear 501 to rotate. A moving mechanism 2 is installed on the lower surface of the outer casing 101. The moving mechanism 2 includes a support rod 201. The upper surface of the support rod 201 is fixedly connected to the bottom of the outer casing 101. A first rotating shaft 202 is fixedly connected to the surface of the support rod 201. A first wheel 203 is movably connected to the surface of the first rotating shaft 202. A second wheel 204 is movably connected to the bottom of the outer casing 101.

[0037] Working principle: When the cleaning mechanism 4 needs to be disassembled for replacement or to clean the hair tangled on its surface, cylinder 301 can be activated. Cylinder 301 retracts, causing connecting plate 302 to rise. A second rotating shaft 303 is movably connected inside connecting plate 302. Using connecting plate 302 to connect cylinder 301 and the second rotating shaft 303 not only allows for convenient control of the raising and lowering of the second rotating shaft 303, but also prevents the rotation of the second rotating shaft 303 from affecting the operation of cylinder 301. When the second rotating shaft 303 rises, the cleaning mechanism 4 installed inside the second rotating shaft 303 rises in height. At this time, simply applying pressure to the locking block 403 engaged inside the second rotating shaft 303 to force it downwards will allow the locking block 403 to move from the second rotating shaft 303. The cleaning mechanism 4 can be easily disassembled by detaching it from the device. During disassembly, the second rotating shaft 303 rises, that is, the protrusion 304 fixed on the surface of the second rotating shaft 303 rises. The second rotating shaft 303 can rotate because the protrusion 304 fixed on the surface of the second rotating shaft 303 is inserted into the square groove on the inner wall of the first gear 501. The height of the first gear 501 in this device is fixed. When the protrusion 304 rises to the set height, the second rotating shaft 303 will no longer rotate. At this time, when replacing the cleaning mechanism 4, there is no need to worry that the device may not close in time, causing the first gear 501 to continue rotating and driving the second rotating shaft 303 to continue rotating, which could cause injury to the cleaning mechanism 4 during the replacement process. This improves the safety of the device.
