Description

Technical Field

[0001] The utility model relates to the technical field of intelligent cleaning equipment, and in particular to a spiral roller brush, a sweeping robot and a base station. Background Art

[0002] A robot vacuum, also known as an automatic sweeper, smart vacuum, or robot vacuum, is a type of smart home appliance that uses artificial intelligence to automatically clean floors. It typically uses a brushing and vacuuming method to collect debris into its own trash collection bin, completing the cleaning process. Generally speaking, any robot that performs sweeping, vacuuming, and mopping is also categorized as a robot vacuum.

[0003] In the prior art, the roller brush rods of sweeping machines mostly adopt a complete cylindrical structure. During the sweeping process, hair is easily entangled on the roller brush rod. After each cleaning, the user needs to manually clean the hair on the roller brush, which is unhygienic and affects the user experience.

[0004] In this regard, the Chinese utility model patent with authorization announcement number CN216932986U discloses a roller brush rod, which is equipped with two independently set roller brush rods on the left and right, and the roller brush rods adopt a spiral structure. When the roller brush rods rotate, the garbage attached to the roller brush rods can be transferred from both sides to the middle gap, thereby solving the problem of hair being entangled on the roller brush rods. The left and right roller brush rods can confine the hair in the middle, ensuring that the hair is sucked into the dust box, avoiding the need for users to manually clean the roller brush rods, and improving the user experience.

[0005] However, in this solution, two motors are required to drive the left and right roller brush rods separately, resulting in poor synchronization. In addition, the motors are wired, making it difficult to remove the roller brush rods from the sweeping robot, and the service life is not long enough, which urgently needs to be improved.

[0048] The present invention will be described in further detail below with reference to the accompanying drawings.

[0049] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0050] This embodiment relates to a spiral roller brush, referring to Figure 1-Figure 3 The robot vacuum cleaner comprises a first roller brush 100 and a second roller brush 200, each of which has a spiral structure. A gap exists between the first and second roller brushes 100 and 200. As the first and second roller brushes 100 and 200 rotate, hair and other debris adhering to the first and second roller brushes 100 and 200 are transferred from the sides to the gap in the middle, significantly reducing the chance of hair becoming entangled. In the robot vacuum cleaner, hair is drawn into the dust bin through the gap between the first and second roller brushes 100 and 200.

[0051] To ensure synchronous rotation of the first roller brush 100 and the second roller brush 200, as shown in the figure, the spiral roller brush also includes a telescopic device. The telescopic device is built into the first roller brush 100, with the telescopic end facing the second roller brush 200. The telescopic end of the telescopic device can move in a straight line along the axial direction. After the telescopic device is placed in the second roller brush 200, the first roller brush 100 can drive the second roller brush 200 to rotate together, ensuring the synchronous rotation of the two roller brushes. After the telescopic device is separated from the second roller brush 200, the gap is exposed. In the sweeping robot, hair passes through the disconnection between the first roller brush 100 and the second roller brush 200 and is sucked into the dust box.

[0052] In order to facilitate the removal of the spiral roller brush and to increase the service life of the product, refer to Figure 1-Figure 3 The spiral roller brush also includes a wireless power receiving coil 300. The wireless power receiving coil 300 is positioned outside the first roller brush 100 and is electrically connected to the telescopic mechanism via a wire. The wireless power receiving coil 300 allows for wireless power to be directly supplied to the telescopic mechanism without requiring contact with an external power source, making the spiral roller brush easier to remove and place, and extending its service life. Specifically, in this embodiment, the first roller brush 100 has a hole through which a wire is passed to electrically connect the wireless power receiving coil 300 to the telescopic mechanism.

[0053] In this embodiment, the first roller brush 100 is externally connected to a drive motor (not shown). After the telescopic device is placed within the second roller brush 200, the drive motor rotates the first roller brush 100, which in turn drives the second roller brush 200. In other embodiments, the drive motor can also be used to drive the second roller brush 200. In this embodiment, the drive motor is the mid-sweep motor in the robot vacuum.

[0054] Reference Figure 1-Figure 5 The telescopic device includes a drive mechanism and a telescopic mechanism 400. The drive mechanism is built into the first roller brush 100, with its output end facing the second roller brush 200. The telescopic mechanism 400 is built into the first roller brush 100 and assembled at the output end of the drive mechanism. It moves linearly along the axial direction under the drive mechanism.

[0055] Specifically in this embodiment, refer to Figure 1-Figure 5, the driving mechanism is a motor 500. The telescopic mechanism 400 includes: a screw 410, a transmission nut 420 and a transmission pin 430. The screw 410 is arranged at the output end of the motor 500, the transmission nut 420 is movably assembled on the screw 410, and the transmission pin 430 is arranged on the screw 410. The motor 500 drives the screw 410 to rotate, and then the transmission nut 420 drives the transmission pin 430 to move linearly along the screw 410. When the spiral roller brush needs to clean the floor, the transmission pin 430 is placed in the second roller brush 200, so that the first roller brush 100 can drive the second roller brush 200 to rotate synchronously; when hair and other garbage need to be sucked into the dust box through the gap between the first roller brush 100 and the second roller brush 200, the transmission pin 430 retreats into the first roller brush 100, exposing the gap in the middle.

[0056] In order to better drive the second roller brush 200 to rotate synchronously, refer to Figure 4-Figure 6 , the cross-section of the transmission pin 430 is polygonal, and the end of the first roller brush 100 in which the transmission pin 430 is built-in has a corresponding first polygonal inner cavity 111, and the end of the second roller brush 200 close to the transmission pin 430 has a corresponding second polygonal inner cavity 211. Specifically in this embodiment, the cross-section of the transmission pin 430 is a regular hexagon, and the first polygonal inner cavity 111 and the second polygonal inner cavity 211 are also regular hexagons. When the first roller brush 100 rotates, with the cooperation of the polygonal transmission pin 430 and the first polygonal inner cavity 111, the transmission pin 430 follows the rotation; with the cooperation of the polygonal transmission pin 430 and the second polygonal inner cavity 211, the second roller brush 200 also follows the rotation. In some embodiments, the cross-section of the transmission pin 430 can also be a regular triangle, a regular quadrilateral, a regular pentagon, etc., or it can be an irregular polygon.

[0057] To better drive the synchronous rotation of the second roller brush, the following embodiment (not shown) can also be used: the outer circumference of the transmission pin is provided with a ridge parallel to the first roller brush; the end of the first roller brush in which the transmission pin is embedded has a corresponding first groove, and the end of the second roller brush closest to the transmission pin has a corresponding second groove. When the first roller brush rotates, the transmission pin rotates with the ridge in conjunction with the first groove; and the second roller brush also rotates with the ridge in conjunction with the second groove.

[0058] To better drive the second roller brush to rotate synchronously, the following embodiment (not shown) can also be used: a groove parallel to the first roller brush is formed on the outer circumference of the transmission pin; the end of the first roller brush housing the transmission pin has a corresponding first ridge, and the end of the second roller brush closest to the transmission pin has a corresponding second ridge. When the first roller brush rotates, the first ridge and the groove cooperate to cause the transmission pin to rotate accordingly; and the second ridge and the groove cooperate to cause the second roller brush to rotate accordingly.

[0059] In one embodiment, referring to Figure 4-Figure 6A retaining ring 212 is provided inside the second roller brush 200 and near one end of the first roller brush 100. A movable cavity is formed between the retaining ring 212 and the second roller brush 200. This movable cavity is also the second polygonal inner cavity 211 mentioned above. The spiral roller brush also includes a spring pin 440 and a spring 450. The spring pin 440 is movably inserted into the movable cavity. The spring pin 440 includes an end portion 441 located in the movable cavity and having a diameter greater than the inner diameter of the retaining ring 212; a head portion 442 located inside the second roller brush 200 and on the other side of the retaining ring 212 and having a diameter greater than the inner diameter of the retaining ring 212; and an insertion portion 443 connecting the head portion 442 and the end portion 441 and having a diameter smaller than the inner diameter of the retaining ring 212. The spring 450 is movably inserted into the movable cavity and sleeved on the insertion portion 443. The diameter of the spring 450 is greater than the inner diameter of the retaining ring 212 but smaller than the diameter of the end portion 441. Due to the provision of the retaining ring 212 , the spring pin 440 will not separate from the second roller brush 200 , thereby ensuring the overall stability of the second roller brush 200 .

[0060] When the transmission pin 430 is not inserted into the second roller brush 200, the end 441 of the spring pin 440 closes one end of the movable cavity, effectively protecting the internal structure of the second roller brush 200 and effectively preventing dust, hair, etc. from entering the second roller brush 200. When the transmission pin 430 moves toward the second roller brush 200, the transmission pin 430 pushes the spring pin 440 to move away from the first roller brush 100, and the spring 450 is in a compressed state; when the transmission pin 430 moves toward the first roller brush 100 (that is, when the transmission pin 430 retracts), the spring 450 resets and the end 441 of the spring pin 440 closes one end of the movable cavity again.

[0061] In one embodiment, referring to Figure 1-Figure 5 The end of the transmission pin 430 near the second roller brush 200 is a closed structure, so that the transmission pin 430 can better push the spring pin 440, better protect the internal structure of the first roller brush 100, and effectively prevent dust, hair, etc. from entering the first roller brush 100. More specifically, the end of the transmission pin 430 near the second roller brush 200 is set to a pointed end, so as to better push the spring pin 440 and better prevent hair from being entangled.

[0062] Reference Figure 1 and Figure 7The spiral roller brush also includes: a first bracket 600 and a second bracket 700. The first bracket 600 includes: a first inner cylinder 610 that is movably placed in the first roller brush 100 and located at one end away from the second roller brush 200; and a first support arm 620 that is connected to the first inner cylinder 610 and extends outward. The second bracket 700 includes: a second inner cylinder 710 that is movably placed in the second roller brush 200 and located at one end away from the first roller brush 100; and a second support arm 720 that is connected to the second inner cylinder 710 and extends outward. The first support arm 620 and the second support arm 720 are used to support the spiral roller brush in the air in the sweeper, so that the first roller brush 100 and the second roller brush 200 can rotate freely to clean the floor.

[0063] In one embodiment, referring to Figure 1-Figure 3 The first roller brush 100 includes: a first roller 110; a first soft rubber 120 with a spiral structure surrounding it, which is mounted on the first roller 110; and first bristles 130 with a spiral structure surrounding the first soft rubber 120. The second roller brush 200 includes: a second roller 210; a second soft rubber 220 with a spiral structure surrounding it, which is mounted on the second roller 210; and second bristles 230 with a spiral structure surrounding the second soft rubber 220. Both the first and second roller brushes 100 and 200 have a double-helix structure, which is more effective in guiding hairs toward the center than a single-helix structure.

[0064] In one embodiment, a sweeping robot (not shown) is provided, comprising: a sweeping robot body; and the aforementioned spiral roller brush disposed within the sweeping robot body. A wireless power supply coil corresponding to the wireless power receiving coil 300 is disposed within the sweeping robot body. The wireless power supply coil supplies power to the wireless power receiving coil 300 through coil induction, thereby driving the retractable device to be placed within the second roller brush 200. A motor is disposed within the sweeping robot body for driving the first roller brush 100 or the second roller brush 200 to rotate.

[0065] In one embodiment, a base station (not shown) is further provided, comprising: a base station body and a sweeping robot as described above, which is removable within the base station. The wireless power supply coil reversely supplies power to the wireless power receiving coil 300 through coil induction, thereby driving the retractable device to retract into the first roller brush 100.

[0066] The operating principle of this spiral roller brush is roughly as follows: the wireless power supply coil within the robot vacuum cleaner supplies power to the wireless power receiving coil 300 through coil induction, which in turn provides power to the motor 500. The motor 500 then drives the screw 410 to rotate, and the drive nut 420 on the screw 410 drives the drive pin 430 to move linearly along the screw 410. The drive pin 430 is inserted into the second roller brush 200, allowing the first roller brush 100 to drive the second roller brush 200 to rotate synchronously. Finally, the robot vacuum cleaner's mid-sweep motor 500 is activated, driving the first and second roller brushes 100 and 200 to rotate. After the robot vacuum cleaner enters the base station, the wireless power supply coil within the base station reversely supplies power to the wireless power receiving coil 300 through coil induction, which in turn drives the drive pin 430 to retract into the first roller brush 100. Hair passes through the gap and is sucked away by the fan.

[0067] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
