Description

Technical Field

[0001] The invention relates to the technical field of electrical appliances, and in particular to an intelligent speed-regulating integrated and efficient floor brush reduction motor. Background Art

[0002] In the field of cleaning equipment, floor brush motors are key components, and their performance directly affects cleaning efficiency and user experience. Traditional floor brush motor designs often use fixed-structure brush heads with fixed bristle density and hardness, which makes it difficult to adapt to the cleaning needs of floors of different materials. For example, using a hard-bristle brush on a soft carpet may damage the carpet fibers; while on a smooth tile floor, a fine-bristle brush may not be able to effectively remove stubborn stains. This single brush head design limits the adaptability and cleaning effect of cleaning equipment in different environments.

[0003] In order to overcome this defect, some floor brush motors with adjustable brush head structures have appeared on the market, but most designs still have certain limitations. These designs often manually adjust the height or angle of the brush head to adapt to different floors, which is cumbersome and not intelligent enough. In addition, some designs are prone to jamming or loosening during the adjustment process, affecting cleaning efficiency and stability. Summary of the invention

[0034] By adopting the above technical solution, when in use, the main body 1 drives the adjustment plate 222 to rotate through the connector 221, and the snap ring 2212 rotates accordingly and engages with the second clamping tooth 2235, thereby driving the mounting plate 223 to rotate clockwise. During the rotation process, the electromagnet 2234 is energized to generate a magnetic field, which attracts the metal block 22422 in the brush 2242 to be close to the electromagnet 2234 to prevent displacement caused by centrifugal force. At the same time, the connecting arm 213 drives the rotating ring 214 to rotate, and the rotating ring 214 squeezes the limiting opening 2122 through the clamping block 1 2141, so that the connecting ring 1 212 rotates (lagging behind the rotating ring 214). During this process, the clamping tooth 1 215 rotates and disengages from the snap ring 1 211 under the action of the limiting hole 2142, and remains separated from the snap ring 1 211. When adjusting the density of the brushes, first turn off the power to the electromagnet 2234, and then the main body 1 rotates the connector 221 in the reverse direction. The adjustment plate 222 squeezes the connecting bolt 2244 through the adjustment slot 2221, and moves the brush three 2243 to adjust the brush spacing, and simultaneously squeezes the spring to keep the spacing consistent. After completion, turn on the power to the electromagnet 2234 to fix the brush position. When rotating in the reverse direction, the rotating ring 214 re-engages the tooth one 215 with the retaining ring one 211 through the limit bolt 216, limiting the mounting plate 223 to rotate only clockwise. When cleaning dust, turn off the power to the electromagnet 2234, and then the main body 1 rotates the connector 221 in a circular manner. The brush two 2242 hits other brushes due to the centrifugal force, generating vibration to remove dust.

[0035] The stopping mechanism 21 includes a snap ring 211 fixedly mounted on the outer wall of the main body 1, the snap ring 211 is rotatably connected to a connecting ring 212 on the outside, a mounting groove 2121 is provided inside the connecting ring 212, a rotating ring 214 is rotatably connected to the inside of the mounting groove 2121, a clamping block 2141 is provided on the outer wall of the rotating ring 214, a limiting opening 2122 is provided on the outer wall of the connecting ring 212 corresponding to the position of the clamping block 2141, the clamping block 2141 is slidably connected to the inner wall of the limiting opening 2122, a limiting hole 2142 is provided on the outer wall of the clamping block 2141, a clamping tooth 215 is hingedly connected to the position of the clamping tooth 215 near the clamping block 2141 inside the connecting ring 212, one end of the clamping tooth 215 extends to the inside of the rotating ring 214, and the outer wall of one end located inside the rotating ring 214 is provided with a A limiting bolt 216 is provided, and the limiting bolt 216 extends to the inside of the limiting hole 2142. A connecting arm 213 is provided on the circumferential outer surface of the rotating ring 214. The connecting arm 213 penetrates the connecting ring 1 212 and extends to its outside, and is fixedly connected to the mounting plate 223. The brush assembly 224 includes a brush 1 2241 fixedly connected to the inner wall of the slide groove 2231, one side of the brush 1 2241 is connected to the brush 2 2242 through a spring 2245, and the side of the brush 2 2242 away from the brush 1 2241 is connected to the brush 3 2243 through a spring 2245, and the end of the brush 2 2242 located inside the slide groove 2231 is fixedly connected with a connecting bolt 2244, and one end of the connecting bolt 2244 extends to the inner wall of the adjusting groove 2221 and is slidably connected to the inner wall of the adjusting groove 2221.

[0036] By adopting the above technical solution, when the mounting plate 223 rotates, the rotating ring 214 is driven to rotate through the connecting arm 213. The rotating ring 214 rotates to a certain angle, and the limiting opening 2122 is squeezed by the clamping block 1 2141, driving the connecting ring 1 212 to rotate (the latter rotates lagging). In this process, the clamping tooth 1 215 rotates and disengages from the clamping ring 1 211 under the action of the limiting hole 2142. When the mounting plate 223 rotates in the reverse direction, the rotating ring 214 rotates again, and the clamping tooth 1 215 is reversely rotated back to its original position through the limiting bolt 216, and re-engages with the clamping ring 1 211, limiting the mounting plate 223 to rotate only clockwise, while the adjusting plate 222 can rotate freely.

[0037] An installation opening 2232 is provided on one side of the slide groove 2231, and an electromagnet 2234 is arranged inside the installation opening 2232. When the electromagnet 2234 is energized, a magnetic field can be generated to control the stability of the brush. A third installation slot 22421 is provided on the position of the brush 2242 located inside the slide groove 2231 near the electromagnet 2234. A metal block 22422 is slidably connected inside the third installation slot 22421. The metal block 22422 fits tightly with the electromagnet 2234 under the action of the magnetic field generated by the electromagnet 2234. The side of the electromagnet 2234 away from the installation opening 2232 is a rough surface. An elastic plate 22423 is arranged between the metal blocks 22422 inside the installation slot 3 22421 to provide a reset force for the metal block 22422 under the action of the magnetic field. The side of the metal block 22422 away from the installation slot 3 22421 is a rough surface to enhance the adsorption force with the electromagnet 2234.

[0038] By adopting the above technical scheme, when adjusting the density between the brushes of the cleaning head 2, the electromagnet 2234 is first powered off, and then the main body 1 drives the adjustment plate 222 and the second retaining ring 2212 to rotate in the opposite direction through the connecting head 221. When the adjustment is completed, the electromagnet 2234 is energized again to generate a magnetic field, thereby pulling the rough surface of the metal block 22422 in the second brush 2242 to be tightly attached to the rough surface of the electromagnet 2234, preventing the second brush 2242 from being displaced under the centrifugal force of rotation. When cleaning with the brush, the electromagnet 2234 is first powered off. Because the electromagnet 2234 does not restrict the second brush 2242, the second brush 2242 will continuously collide with the first brush 2241 and the third brush 2243 due to the centrifugal force, and the dust is cleaned by vibration generated by the collision.

[0039] When the present invention is in use, the floor brush reduction motor includes a main body 1 and a cleaning head 2, and the cleaning head 2 includes a stop mechanism 21 and a brush plate mechanism 22;

The limiting bolt 216 extends to the inside of the limiting hole 2142. The height of the limiting hole 2142 is greater than the diameter of the limiting bolt 216. A connecting arm 213 is arranged on the circumferential outer surface of the rotating ring 214. The connecting arm 213 passes through the connecting ring 212 and extends to the outside thereof.

[0041] The brush assembly 224 includes a mounting plate 223 fixedly connected to the inner wall of the connecting arm 213, a slide groove 2231 is provided on the outer wall of the mounting plate 223, a mounting opening 2232 is provided inside the slide groove 2231 near one side, an electromagnet 2234 is provided inside the mounting opening 2232, and the side of the electromagnet 2234 away from the mounting opening 2232 is a rough surface, the brush assembly 224 also includes a connector 221 fixedly connected to the output end of the main body 1, an adjustment plate 222 is fixedly connected to the outer wall of the connector 221, the adjustment plate 222 is slidably connected to the outer wall of the mounting plate 223, an adjustment groove 2221 is provided on the side of the adjustment plate 222 close to the mounting plate 223, and the mounting plate 223 is close to the mounting plate 223. A docking port 2233 is provided at the position of the connecting head 221, one end of the connecting head 221 extends into the interior of the docking port 2233, and a mounting groove 2211 is provided on the circumferential outer surface of one end of the connecting head 221 located inside the docking port 2233, a retaining ring 2212 is fixedly connected inside the mounting groove 2211, a tooth 2235 is hinged inside the docking port 2233, the tooth 2235 is slidably connected to the outer wall of the retaining ring 2212, a spring 2236 connected to the inner wall of the docking port 2233 is provided on the side of the tooth 2235 away from the retaining ring 2212, and a brush assembly 224 is provided in the sliding groove 2231 on the side of the mounting plate 223 away from the adjusting plate 222.

[0042] The brush assembly 224 includes a brush 1 2241 fixedly connected to the inner wall of the slide groove 2231, one side of the brush 1 2241 is connected to a brush 2 2242 via a spring 2245, and the side of the brush 2 2242 away from the brush 1 2241 is connected to a brush 3 2243 via a spring 2245, one end of the brush 2 2242 and the brush 3 2243 extends into the slide groove 2231 and is slidably connected, and the end of the brush 3 2243 located in the slide groove 2231 is fixedly connected to a connecting bolt 2244, and the connecting bolt 2244 is fixedly connected to the end of the brush 3 2243 located in the slide groove 2231. One end of the connecting bolt 2244 extends to the inner wall of the adjusting groove 2221 and is slidably connected to the inner wall of the adjusting groove 2221. The brush 2242 is located inside the slide groove 2231 near the electromagnet 2234 and is provided with an installation groove 3 22421. A metal block 22422 is slidably connected inside the installation groove 3 22421. An elastic plate 22423 is provided inside the installation groove 3 22421 between the metal blocks 22422. The side of the metal block 22422 away from the installation groove 3 22421 is a rough surface.

[0043] When in use, the main body 1 drives the adjustment plate 222 to rotate through the connecting head 221, and the connecting head 221 drives the second snap ring 2212 to rotate. The second clamping tooth 2235 is engaged with the second snap ring 2212. The rotation of the second snap ring 2212 drives the mounting plate 223 to rotate clockwise through the second clamping tooth 2235. At the same time, when the mounting plate 223 rotates, the electromagnet 2234 is energized. When the electromagnet 2234 is energized, a magnetic field is generated, thereby pulling the rough surface of the metal block 22422 in the second brush 2242 to fit tightly against the rough surface of the electromagnet 2234, so as to prevent the second brush 2242 from being displaced under the centrifugal force of rotation.

[0044] When the mounting plate 223 rotates, the rotating ring 214 is driven to rotate through the connecting arm 213. After the rotating ring 214 rotates a certain angle, the limiting opening 2122 is squeezed by the clamping block 2141, thereby driving the connecting ring 212 to rotate. The rotation of the connecting ring 212 is later than that of the rotating ring 214. Therefore, when the rotating ring 214 rotates, the clamping tooth 215 is pulled through the limiting hole 2142. When the clamping tooth 215 is pulled, it will rotate a certain angle around the connection point with the connecting ring 212. The rotation at a certain angle will cause the clamping tooth 215 to disengage from the clamping ring 211. After the connecting ring 212 starts to rotate, the clamping tooth 215 still remains away from the clamping ring 211.

[0045] When adjusting the density between the brushes of the cleaning head 2, firstly, the electromagnet 2234 is powered off, and then the main body 1 drives the adjustment plate 222 and the second snap ring 2212 to rotate in the opposite direction through the connecting head 221. When the second snap ring 2212 rotates in the opposite direction, it will not get stuck due to the extrusion of the inclined surface, so it cannot drive the mounting plate 223 to rotate in the opposite direction. When the adjustment plate 222 rotates in the opposite direction, it will squeeze the connecting bolt 2244 in the brush assembly 224 through the adjusting groove 2221, and by squeezing the connecting bolt 2244, it drives the third brush 2243 to move along the slide groove 2231. For example, when moving toward the second brush 2242, the distances between the third brush 2243, the second brush 2242, and the first brush 2241 will be kept relatively synchronized by squeezing the spring 2245. When the adjustment is completed Then, the electromagnet 2234 is energized again to generate a magnetic field, thereby pulling the rough surface of the metal block 22422 in the brush 2242 to fit tightly against the rough surface of the electromagnet 2234, preventing the brush 2242 from being displaced under the centrifugal force of rotation. To prevent the mounting plate 223 from being driven, the rotating ring 214 is driven to rotate through the connecting arm 213 when the mounting plate 223 rotates in the reverse direction. When the rotating ring 214 rotates, it squeezes the limiting bolt 216 of the latch tooth 1 215 through the limiting hole 2142, so that the latch tooth 1 215 rotates in the reverse direction at a certain angle with the connection point with the connecting ring 1 212 as the center, thereby engaging the latch tooth 1 215 with the retaining ring 1 211, so that the mounting plate 223 can only rotate clockwise while the adjusting plate 222 can rotate arbitrarily.

[0046] After the brush has been used for a certain period of time, dust will accumulate and need to be cleaned. First, the electromagnet 2234 is powered off, and then the main body 1 drives the connecting head 221 to rotate counterclockwise and clockwise. Because the electromagnet 2234 does not restrict the brush 2 2242, the brush 2 2242 will continuously collide with the brush 1 2241 and the brush 3 2243 due to the centrifugal force, and the dust is cleaned by the vibration generated by the collision.

[0047] Through the unique stop mechanism 21 (grip 1 215 cooperates with snap ring 1 211, and grip 2235 interacts with snap ring 2212) and the brush plate mechanism 22 (adjustment plate 222 is slidably connected with mounting plate 223, and brush assembly 224 is elastically connected), adaptive adjustment of the brush head structure is achieved, solving the problem of the inadaptability of the traditional fixed brush head. The application of electromagnet 2234 prevents the displacement of brush 2 2242 and realizes the self-cleaning function when the power is off. The design of the floor brush reduction motor of the present invention simplifies maintenance operations and ensures stability and durability for long-term use.
