Description

Technical Field

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

[0002] In the field of cleaning equipment, the floor brush motor, as a key component, directly affects the cleaning efficiency and user experience. Traditional floor brush motor designs often use a fixed-structure brush head, with the bristle density and hardness remaining unchanged, making it difficult to meet the cleaning requirements of different floor materials. For example, using a hard brush on a soft carpet may damage the carpet fibers; while on a smooth tile floor, a fine 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] To overcome this defect, some floor brush motors with adjustable brush head structures have emerged 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 the cleaning efficiency and stability. Summary of the Invention

[0004] An intelligent speed-regulating integrated high-efficiency floor brush reduction motor of the present invention is provided to solve the problem that the brush head structure of the existing floor brush motor is fixed, the bristle density and hardness are non-adjustable, and it is difficult to meet the cleaning requirements of different floor materials as described in the above background art.

[0005] To solve the above technical problems, a technical solution adopted by the present invention is: to provide an intelligent speed-regulating integrated high-efficiency floor brush reduction motor, including a main body and a cleaning head. The cleaning head includes a stop mechanism and a brush plate mechanism. The brush plate mechanism includes a connection head fixedly connected to the output end of the main body. An adjustment plate is fixedly connected to the outer wall of the connection head. An installation plate is arranged on the side of the adjustment plate away from the main body. The adjustment plate is slidably connected to the installation plate. An adjustment groove is opened on the side of the adjustment plate close to the installation plate. A sliding groove is penetrated through the outer wall of the installation plate. An interface is opened at the position of the installation plate close to the connection head. One end of the connection head extends into the interface. An installation groove two is opened on the circumferential outer surface of the end of the connection head located inside the interface. A snap ring two is fixedly connected inside the installation groove two. A snap tooth two is hinged inside the interface. The snap tooth two is slidably connected to the outer wall of the snap ring two. A spring one connected to the inner wall of the interface is arranged on the side of the snap tooth two away from the snap ring two. A brush component is arranged in the sliding groove on the side of the installation plate away from the adjustment plate.

[0006] The present invention is further configured such that the stopping mechanism includes a first clamping ring fixedly installed on the outer wall of the main body. A first connecting ring is rotatably connected to the outside of the first clamping ring. An installation groove is formed inside the first connecting ring. A rotating ring is rotatably connected inside the installation groove. A first clamping block is provided on the outer wall of the rotating ring. A limiting opening is formed in the outer wall of the first connecting ring corresponding to the position of the first clamping block. The first clamping block is slidably connected to the inner wall of the limiting opening. A limiting hole is formed through the outer wall of the first clamping block. A first clamping tooth is hinged inside the first connecting ring near the first clamping block. One end of the first clamping tooth extends into the rotating ring, and a limiting bolt is provided on the outer wall of the end located inside the rotating ring. The limiting bolt extends into the limiting hole.

[0007] The present invention is further configured such that a connecting arm is provided on the circumferential outer surface of the rotating ring. The connecting arm penetrates through the first connecting ring and extends to its outside, and is fixedly connected to the mounting plate.

[0008] The present invention is further configured such that the brush assembly includes a first brush fixedly connected to the inner wall of the sliding groove. A second brush is connected to one side of the first brush through a second spring. A third brush is connected to the side of the second brush away from the first brush through a second spring. A connecting bolt is fixedly connected to the end of the third brush located inside the sliding groove. One end of the connecting bolt extends into the inner wall of the adjusting groove and is slidably connected to the inner wall of the adjusting groove.

[0009] The present invention is further configured such that an installation opening is formed on one side inside the sliding groove. An electromagnet is provided inside the installation opening. When the electromagnet is energized, it can generate a magnetic field to control the stability of the brush. An installation groove is formed inside the second brush near the electromagnet. A metal block is slidably connected inside the installation groove. The metal block is closely attached to the electromagnet under the action of the magnetic field generated by the electromagnet.

[0010] The present invention is further configured such that the side of the electromagnet away from the installation opening is a rough surface. An elastic plate is provided between the metal blocks inside the installation groove to provide a restoring force for the metal blocks under the action of the magnetic field; the side of the metal block away from the installation groove is a rough surface to enhance the adsorption force with the electromagnet.

[0011] The beneficial effects of an intelligent speed-regulating integrated high-efficiency floor brush reduction motor of the present invention:

[0012] 1. Through the unique design of the stopping mechanism and the brush plate mechanism, the adaptive adjustment of the brush head structure is realized. The sliding connection between the adjusting plate and the mounting plate in the brush plate mechanism, as well as the elastic connection design of the brush assembly, enable the density and hardness of the brush to be flexibly adjusted according to the ground material, avoiding the problem of inadaptability of the traditional fixed brush head design to different grounds.

[0013] 2. The cooperation between the first locking tooth and the first snap ring in the stopping mechanism, as well as the interaction between the second locking tooth and the second snap ring, ensure the stable locking of the brush head during clockwise rotation and the flexible unlocking during counterclockwise rotation. This design not only improves the stability during the cleaning process but also simplifies the operation process of brush head adjustment, realizing intelligent brush head management.

[0014] 3. The ingenious application of the electromagnet, by generating a magnetic field to attract the metal block, effectively prevents the displacement of the second brush due to centrifugal force during rotation, ensuring the stability of the brush assembly and the cleaning effect. At the same time, the power-off and power-on control of the electromagnet also realizes the self-cleaning function of the brush, cleaning the accumulated dust through the impact and vibration between the brushes.

[0015] 3. The design of the floor brush reduction motor of the present invention enables the brush assembly to achieve self-cleaning through cyclic rotation in the power-off state without manual disassembly and cleaning, greatly reducing the maintenance cost and operation difficulty. In addition, the precise cooperation and reliable connection between various components also ensure the stability and durability during long-term use. Brief Description of the Drawings

[0033] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and 5 、 Figure 6 、 Figure 7 、 Figure 8, an intelligent speed-regulating integrated high-efficiency floor brush reduction motor, comprising a main body 1 and a cleaning head 2. The cleaning head 2 includes a stop mechanism 21 and a brush plate mechanism 22; the brush plate mechanism 22 includes a connection head 221 fixedly connected to the output end of the main body 1. An adjusting plate 222 is fixedly connected to the outer wall of the connection head 221. On the side of the adjusting plate 222 away from the main body 1, there is an installation plate 223. The adjusting plate 222 is slidably connected to the installation plate 223. On the side of the adjusting plate 222 close to the installation plate 223, there is an adjusting groove 2221. A sliding groove 2231 is penetrated through the outer wall of the installation plate 223. At the position of the installation plate 223 close to the connection head 221, there is a docking port 2233. One end of the connection head 221 extends into the docking port 2233. On the outer circumferential surface of the end of the connection head 221 located inside the docking port 2233, there is a second installation groove 2211. A second snap ring 2212 is fixedly connected inside the second installation groove 2211. A second locking tooth 2235 is hinged inside the docking port 2233. The second locking tooth 2235 is slidably connected to the outer wall of the second snap ring 2212. On the side of the second locking tooth 2235 away from the second snap ring 2212, there is a first spring 2236 connected to the inner wall of the docking port 2233. Inside the sliding groove 2231 on the side of the installation plate 223 away from the adjusting plate 222, there is a brush assembly 224.

[0034] By adopting the above technical solution, during use, the main body 1 drives the adjusting plate 222 to rotate through the connection head 221. At the same time, the second snap ring 2212 rotates accordingly and engages with the second locking tooth 2235, thereby driving the installation plate 223 to rotate clockwise. During the rotation process, the electromagnet 2234 is energized to generate a magnetic field, attracting the metal block 22422 in the second brush 2242 to closely adhere 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. The rotating ring 214 squeezes the limiting port 2122 through the first engaging block 2141, causing the first connecting ring 212 to rotate (lagging behind the rotating ring 214). During this process, the first locking tooth 215 rotates under the action of the limiting hole 2142 and disengages from the first snap ring 211, maintaining a separated state from the first snap ring 211. When adjusting the density of the brushes, first cut off the power supply of the electromagnet 2234, and the main body 1 rotates the connection head 221 in the reverse direction. The adjusting plate 222 squeezes the connecting bolt 2244 through the adjusting groove 2221 to move the third brush 2243 to adjust the brush spacing, and simultaneously squeezes the spring to keep the spacing consistent. After completion, energize the electromagnet 2234 to fix the position of the brushes. When rotating in the reverse direction, the rotating ring 214 causes the first locking tooth 215 to engage with the first snap ring 211 again through the limiting bolt 216, restricting the installation plate 223 to rotate only clockwise. When cleaning dust, cut off the power supply of the electromagnet 2234, and the main body 1 rotates the connection head 221 in a cycle. The second brush 2242 impacts other brushes due to centrifugal force, generating vibrations to remove dust.

[0035] The stop mechanism 21 includes a first clamping ring 211 fixedly installed on the outer wall of the main body 1. A first connecting ring 212 is rotatably connected to the outside of the first clamping ring 211. An installation groove 2121 is formed inside the first connecting ring 212. A rotating ring 214 is rotatably connected inside the installation groove 2121. A first clamping block 2141 is arranged on the outer wall of the rotating ring 214. A limiting port 2122 is formed at the position corresponding to the first clamping block 2141 on the outer wall of the first connecting ring 212. The first clamping block 2141 is slidably connected to the inner wall of the limiting port 2122. A limiting hole 2142 is formed through the outer wall of the first clamping block 2141. A first clamping tooth 215 is hinged inside the first connecting ring 212 near the first clamping block 2141. One end of the first clamping tooth 215 extends into the rotating ring 214, and a limiting bolt 216 is arranged on the outer wall of the end located inside the rotating ring 214. The limiting bolt 216 extends into the limiting hole 2142. A connecting arm 213 is arranged on the circumferential outer surface of the rotating ring 214. The connecting arm 213 penetrates through the first connecting ring 212 and extends to its outside, and is fixedly connected to the mounting plate 223. The brush assembly 224 includes a first brush 2241 fixedly connected to the inner wall of the sliding groove 2231. A second brush 2242 is connected to one side of the first brush 2241 through a second spring 2245. A third brush 2243 is connected to the side of the second brush 2242 away from the first brush 2241 through a second spring 2245. A connecting bolt 2244 is fixedly connected to the end of the third brush 2243 located inside the sliding groove 2231. One end of the connecting bolt 2244 extends into 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. When the rotating ring 214 rotates to a certain angle, the first clamping block 2141 squeezes the limiting port 2122, driving the first connecting ring 212 to rotate (the latter rotates with a delay). During this process, the first clamping tooth 215 rotates and disengages from the first clamping ring 211 under the action of the limiting hole 2142. When the mounting plate 223 rotates reversely, the rotating ring 214 rotates again, and the first clamping tooth 215 rotates reversely and returns to its position through the limiting bolt 216, re-engaging with the first clamping ring 211, restricting the mounting plate 223 to rotate only clockwise, while the adjusting plate 222 can rotate freely.

[0037] On one side inside the sliding groove 2231, there is an installation opening 2232. An electromagnet 2234 is arranged inside the installation opening 2232. When the electromagnet 2234 is energized, it can generate a magnetic field to control the stability of the brush. A third installation groove 22421 is provided at a position inside the sliding groove 2231 close to the electromagnet 2234 for the second brush 2242. A metal block 22422 is slidably connected inside the third installation groove 22421. The metal block 22422 is closely attached to 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 third installation groove 22421 to provide a restoring force for the metal block 22422 under the action of the magnetic field. The side of the metal block 22422 away from the third installation groove 22421 is a rough surface to enhance the adsorption force with the electromagnet 2234.

[0038] By adopting the above technical solution, when adjusting the density between the brushes of the cleaning head 2, first, the electromagnet 2234 is powered off. Then, the main body 1 drives the adjusting plate 222 and the second snap ring 2212 to rotate reversely 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 closely adhere to the rough surface of the electromagnet 2234, preventing the second brush 2242 from generating displacement under the centrifugal force during rotation. During brush cleaning, first, the electromagnet 2234 is powered off. Since the electromagnet 2234 does not restrict the second brush 2242, the second brush 2242 will continuously hit the first brush 2241 and the third brush 2243 due to centrifugal force, and generate vibrations through the impacts to clean the dust.

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

[0040] The stop mechanism 21 includes a first snap ring 211 fixedly installed on the outer wall of the main body 1. A first connecting ring 212 is rotatably connected to the outside of the first snap ring 211. An installation groove 2121 is provided inside the first connecting ring 212. A rotating ring 214 is rotatably connected inside the installation groove 2121. A first clamping block 2141 is provided on the outer wall of the rotating ring 214. A limiting port 2122 is provided on the outer wall of the first connecting ring 212 corresponding to the position of the first clamping block 2141. The first clamping block 2141 is slidably connected to the inner wall of the limiting port 2122. A limiting hole 2142 is provided through the outer wall of the first clamping block 2141. A first clamping tooth 215 is hinged inside the first connecting ring 212 near the first clamping block 2141. One end of the first clamping tooth 215 extends into the rotating ring 214, and a limiting bolt 216 is provided on the outer wall of the end located inside the rotating ring 214. The limiting bolt 216 extends into 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 provided on the circumferential outer surface of the rotating ring 214. The connecting arm 213 penetrates through the first connecting ring 212 and extends to its outside.

[0041] The brush assembly 224 includes a mounting plate 223 fixedly connected to the inner wall of the connecting arm 213. A sliding groove 2231 is provided through the outer wall of the mounting plate 223. An installation port 2232 is provided near one side inside the sliding groove 2231. An electromagnet 2234 is provided inside the installation port 2232. The side of the electromagnet 2234 away from the installation port 2232 is a rough surface. The brush assembly 224 also includes a connecting head 221 fixedly connected to the output end of the main body 1. An adjusting plate 222 is fixedly connected to the outer wall of the connecting head 221. The adjusting plate 222 is slidably connected to the outer wall of the mounting plate 223. An adjusting groove 2221 is provided on the side of the adjusting plate 222 close to the mounting plate 223. A docking port 2233 is provided on the mounting plate 223 near the connecting head 221. One end of the connecting head 221 extends into the docking port 2233, and an installation groove 2211 is provided on the circumferential outer surface of the end of the connecting head 221 located inside the docking port 2233. A second snap ring 2212 is fixedly connected inside the installation groove 2211. A second clamping tooth 2235 is hinged inside the docking port 2233. The second clamping tooth 2235 is slidably connected to the outer wall of the second snap ring 2212. A first spring 2236 connected to the inner wall of the docking port 2233 is provided on the side of the second clamping tooth 2235 away from the second snap ring 2212. A brush assembly 224 is provided inside 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 first brush 2241 fixedly connected to the inner wall of the chute 2231. One side of the first brush 2241 is connected to a second brush 2242 through a second spring 2245. One side of the second brush 2242 away from the first brush 2241 is connected to a third brush 2243 through a second spring 2245. One ends of the second brush 2242 and the third brush 2243 extend into the chute 2231 and are slidably connected. The end of the third brush 2243 located inside the chute 2231 is fixedly connected to a connecting bolt 2244. One end of the connecting bolt 2244 extends to the inner wall of the adjustment groove 2221 and is slidably connected to the inner wall of the adjustment groove 2221. An installation groove three 22421 is opened at a position of the second brush 2242 close to the electromagnet 2234 inside the chute 2231. A metal block 22422 is slidably connected inside the installation groove three 22421. An elastic plate 22423 is arranged between the metal blocks 22422 inside the installation groove three 22421. The side of the metal block 22422 away from the installation groove three 22421 is a rough surface.

[0043] When in use, the main body 1 drives the adjustment plate 222 to rotate through the connector 221. At the same time, the connector 221 will drive the second snap ring 2212 to rotate. The second gear teeth 2235 are engaged with the second snap ring 2212. The rotation of the second snap ring 2212 will drive the mounting plate 223 to rotate clockwise through the second gear teeth 2235. At the same time, when the mounting plate 223 rotates, it will energize the electromagnet 2234. When the electromagnet 2234 is energized, it will generate a magnetic field to pull the rough surface of the metal block 22422 in the second brush 2242 to closely adhere to the rough surface of the electromagnet 2234, which can prevent the second brush 2242 from generating displacement under the centrifugal force during rotation.

[0044] When the mounting plate 223 rotates, it will drive the rotating ring 214 to rotate through the connecting arm 213. After the rotating ring 214 rotates a certain angle, it will drive the first connecting ring 212 to rotate by pressing the limiting port 2122 through the first engaging block 2141. The rotation of the first connecting ring 212 lags behind that of the rotating ring 214. Therefore, when the rotating ring 214 rotates, it will pull the first gear teeth 215 through the limiting hole 2142. When pulling the first gear teeth 215, it will rotate a certain angle with the connection point with the first connecting ring 212 as the center. This certain angle of rotation will cause the first gear teeth 215 to disengage from the first snap ring 211. After the first connecting ring 212 starts to rotate subsequently, the first gear teeth 215 still remain away from the first snap ring 211.

[0045] When adjusting the density between the brushes of the cleaning head 2, first cut off the power supply of the electromagnet 2234. Then, the main body 1 drives the adjusting plate 222 and the second snap ring 2212 to rotate reversely through the connecting head 221. When the second snap ring 2212 rotates reversely, it will not be stuck due to the inclined plane extrusion, so it cannot drive the mounting plate 223 to rotate reversely. When the adjusting plate 222 rotates reversely, it will squeeze the connecting bolt 2244 in the brush assembly 224 through the adjusting groove 2221. By squeezing the connecting bolt 2244, it drives the third brush 2243 to move along the sliding groove 2231. When moving towards the second brush 2242, it will keep the distance between the third brush 2243, the second brush 2242, and the first brush 2241 relatively synchronous by squeezing the second spring 2245. After the adjustment is completed, the electromagnet 2234 is energized again to generate a magnetic field, which pulls the rough surface of the metal block 22422 in the second brush 2242 to closely adhere to the rough surface of the electromagnet 2234, preventing the second brush 2242 from displacing under the centrifugal force during rotation. To prevent the mounting plate 223 from being driven, when the mounting plate 223 rotates reversely, it will drive the rotating ring 214 to rotate through the connecting arm 213. When the rotating ring 214 rotates, it will squeeze the limiting bolt 216 of the first engaging tooth 215 through the limiting hole 2142, so that the first engaging tooth 215 will rotate reversely by a certain angle with the connection point with the first connecting ring 212 as the center, and then the first engaging tooth 215 will be engaged with the first snap ring 211. Therefore, the mounting plate 223 can only rotate clockwise while the adjusting plate 222 can rotate arbitrarily.

[0046] When the brushes need to be cleaned after accumulating dust after a certain period of use, first cut off the power supply of the electromagnet 2234. Then, the main body 1 drives the connecting head 221 to rotate counterclockwise and clockwise in a cycle. Since the electromagnet 2234 does not restrict the second brush 2242, the second brush 2242 will continuously hit the first brush 2241 and the third brush 2243 due to the centrifugal force, and generate vibrations through the impacts to clean the dust.

[0047] Through the unique stop mechanism 21 (the first engaging tooth 215 cooperates with the first snap ring 211, and the second engaging tooth 2235 interacts with the second snap ring 2212) and the brush plate mechanism 22 (the adjusting plate 222 is slidably connected to the mounting plate 223, and the brush assembly 224 is elastically connected), the adaptive adjustment of the brush head structure is realized, and the problem of inadaptability of the traditional fixed brush head is solved. The application of the electromagnet 2234 prevents the displacement of the second brush 2242 and realizes the power-off self-cleaning function at the same time. The design of the floor brush reduction motor of the present invention simplifies the maintenance operation and ensures the stability and durability of long-term use.
