Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to an intelligent induction vacuum cleaner brush structure. Background Art

[0002] A vacuum cleaner is an electrical appliance used for floor cleaning. Common vacuum cleaners can be divided into vertical, horizontal and portable types. The basic structure of a vacuum cleaner can be divided into five parts, including the power part, the filtration system, the functional part, the protection measures and several accessories. The fan impeller of the vacuum cleaner is driven at high speed by the motor to discharge the air in the impeller out of the fan at high speed, while the air in the dust collection part is continuously and quickly replenished into the fan, thereby forming a high pressure difference with the outside world, and sucking the external dust and impurities into the body for collection.

[0003] In order to improve the cleaning effect of the vacuum cleaner on the ground, a rotatable cleaning brush is usually arranged on the bottom surface of the vacuum cleaner. When the vacuum cleaner is working, the cleaning brush rotates under the drive of the driving device and cleans the ground more thoroughly.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the speed of the cleaning brush is usually a fixed value when the cleaning brush is used to clean the floor. However, for floors of different materials, using a cleaning brush with a uniform speed to clean the floor may cause wear on the floor and reduce the service life of the floor. In addition, for floors with certain slight protrusions, a high-speed rotating cleaning brush may also cause excessive cleaning of the protruding floor, which may easily damage the floor coating. Summary of the invention

[0005] In order to improve the cleaning quality of the floor and make the cleaning brush suitable for floors in different conditions, the present application provides an intelligent induction vacuum cleaner brush structure.

[0006] The present application provides an intelligent inductive vacuum cleaner brush structure that adopts the following technical solution: A smart induction vacuum cleaner brush structure comprises a body and a cleaning brush rotatably arranged on the bottom surface thereof, and also comprises a transmission assembly, wherein the transmission assembly comprises a driving source, a flywheel, a transmission pressure plate and a rotating shaft, wherein the driving source is arranged on the body, the flywheel is transmission-connected to the driving source, one end of the rotating shaft is coaxially rotationally connected to a side of the flywheel away from the driving source, and the other end is rotationally connected to the body, the cleaning brush comprises a rubber roller and a brush layer arranged on its surface, the rubber roller is provided with a central cavity along the central axis, the rubber roller is connected to the rotating shaft through the central cavity, the transmission pressure plate is slidably sleeved on the rotating shaft, a linkage key is arranged on the rotating shaft, a transmission key groove slidably matched with the linkage key is arranged on the inner ring wall of the transmission pressure plate, and a driving member for driving the transmission pressure plate to slide along the direction close to or away from the flywheel is arranged on the transmission shaft.

[0007] By adopting the above technical solution, the driving source drives the flywheel to rotate. Under normal circumstances, the transmission pressure plate is pressed against one side of the flywheel, and the two rotate synchronously, and the rotating shaft rotates with the transmission pressure plate. When there is a protrusion on the ground, the driving member causes the transmission pressure plate to slide slightly in the direction away from the flywheel, and the friction between the two is reduced, so that the rotation speed of the rotating shaft is lower than the speed of the flywheel, thereby achieving deceleration of the rotating shaft. Through the mutual cooperation of the machine body, the cleaning brush and the transmission assembly, the rotation speed of the cleaning brush is adjusted, which has the effect of improving the cleaning quality of the ground and making the cleaning brush suitable for ground in different conditions.

[0008] Optionally, the driving member includes an extrusion air chamber, a mounting spring sheet, a mounting ring, a sliding ring and a first cylinder, a gap is left between the central cavity and the rotating shaft, a plurality of the extrusion air chambers are arranged in the gap between the central cavity and the rotating shaft, the extrusion air chamber includes a fixed box body connected to the rotating shaft and a sliding top cover slidably arranged at an open end of the fixed box body, the sliding top cover is arranged on a side of the fixed box body close to the inner wall of the central cavity, the first cylinder is arranged on the rotating shaft, a connecting manifold is arranged between the first cylinder and the extrusion air chamber, and the sliding ring slides The sliding ring is arranged on the rotating shaft, the sliding ring is arranged between the first cylinder and the transmission pressure plate, the first cylinder is connected to the sliding ring in transmission connection, the mounting spring sheet comprises a spring ring and a plurality of spring plates obliquely arranged on the inner side thereof, the mounting spring sheet is sleeved on the rotating shaft, the spring ring is connected to the transmission pressure plate, the spring plate extends toward the sliding ring and abuts against it, and in a natural state, the transmission pressure plate is pressed against the flywheel under the action of the mounting spring sheet, the mounting ring is arranged on the rotating shaft, and the mounting ring is arranged between the linkage key and the spring plate.

[0009] By adopting the above technical solution, when there is a protrusion on the ground, relative movement occurs between the rotating shaft and the cleaning brush, and the inner ring wall of the central cavity squeezes the extrusion air chamber. The gas in the extrusion air chamber enters the cylinder body of the first cylinder through the connecting manifold. The output shaft of the first cylinder extends and pushes the slip ring toward the direction close to the installation spring sheet. The spring ring is tilted up under the drive of the slip ring and the limiting action of the installation ring, driving the transmission pressure plate to move slightly in the direction away from the flywheel, and the friction between the two is reduced, so that the speed of the rotating shaft is reduced.

[0010] Optionally, a plurality of plug-in rods are connected to the rotating shaft along its radial direction, and a plurality of plug-in holes corresponding one-to-one to and plug-matching with the plug-in rods are opened on the inner annular wall of the central cavity, the inner cavity of the plug-in holes is larger than the plug-in rods, and a plurality of supporting springs are connected between the inner annular wall of the central cavity and the rotating shaft.

[0011] By adopting the above technical solution, the arrangement of the plug rod and the plug hole realizes the driving of the cleaning brush by the rotating shaft, and also allows a slight displacement between the two, so as to squeeze and drive the extrusion air chamber. The support spring is arranged between the rotating shaft and the inner ring wall of the central cavity, which, on the one hand, enables the rotating shaft to maintain coaxiality with the cleaning brush, and on the other hand, reduces the possibility of the cleaning brush squeezing the extrusion air chamber under the action of its own weight.

[0012] Optionally, a plurality of friction blocks are provided on a side of the transmission pressure plate close to the flywheel, and the friction blocks are detachably connected to the transmission pressure plate.

[0013] By adopting the above technical solution, the friction block increases the friction between the transmission pressure plate and the flywheel. Since the friction block is detachably connected to the transmission pressure plate, when the friction block becomes thinner due to friction, it can be removed and replaced.

[0014] Optionally, a friction assembly is provided on the machine body, and the friction assembly includes an air supply hose, a second cylinder, a friction inclined plate and a connecting shaft. The air supply hose is connected to the connecting manifold, and the other end of the air supply hose is connected to the second cylinder. The second cylinder is connected to the machine body, and the output shaft of the second cylinder extends vertically upward. The connecting shaft is connected to one of the opposite sides of the friction inclined plate, and the connecting shaft is rotatably connected to the machine body. The friction inclined plate is arranged above the second cylinder, and in a natural state, the friction inclined plate and the cleaning brush are spaced apart.

[0015] By adopting the above technical solution, when one of the extrusion air chambers is squeezed, the gas enters the cylinder body of the second cylinder, the output shaft of the second cylinder extends and lifts one end of the friction ramp plate, and the other end of the friction ramp plate rotates downward and abuts against the cleaning brush to generate friction, thereby achieving further deceleration of the cleaning brush.

[0016] Optionally, a return torsion spring is provided on the connecting shaft, one end of the return torsion spring is connected to the machine body, and the other end is connected to the friction inclined plate. In a natural state, the friction inclined plate abuts against the output shaft of the second cylinder under the action of the return torsion spring, and the friction inclined plate and the cleaning brush are spaced apart.

[0017] By adopting the above technical solution, when the ground is flat, the output shaft of the second cylinder is shortened, and the friction ramp plate rotates in the opposite direction to reset under the action of the reset torsion spring, so that the friction ramp plate is separated from the cleaning brush again.

[0018] Optionally, a plurality of connecting strips are provided on the inner side of the brush layer along the length direction of the cleaning brush, and a plurality of connecting grooves corresponding to the connecting strips are opened on the outer wall of the rubber roller along its length direction, and the connecting strips are embedded in the connecting grooves.

[0019] By adopting the above technical solution, the connecting strip is embedded in the corresponding connecting groove, thereby realizing the detachable connection between the brush layer and the rubber roller, and the user can replace different brush layers according to different floor materials.

[0020] Optionally, a material detection sensor is provided on the machine body, and the material detection sensor is electrically connected to the driving source.

[0021] By adopting the above technical solution, when cleaning the ground, the material detection sensor detects the ground material and transmits the data to the driving source, and the driving source outputs a suitable rotation speed to avoid damaging the ground due to too high a rotation speed or failing to clean due to too low a rotation speed.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the machine body, the cleaning brush and the transmission assembly, the speed of the cleaning brush can be adjusted, which has the effect of improving the cleaning quality of the ground and making the cleaning brush suitable for the ground in different conditions; 2.

[0033] Reference Figure 2The inner diameter of the central cavity 31 is larger than the diameter of the rotating shaft 4.

[0036] Reference Figure 3 and Figure 4The friction assembly 5 is arranged on the machine body 1, and the friction assembly 5 includes an air hose 51, a second cylinder 52, a support block 53, a friction inclined plate 54, a connecting shaft 55 and a reset torsion spring 56. The second cylinder 52 is vertically arranged on the machine body 1, and the output shaft of the second cylinder 52 extends vertically upward and is connected to the support block 53. The two ends of the air hose 51 are connected to the cylinder body of the second cylinder 52 and the connecting manifold 208 respectively. The friction inclined plate 54 is arranged above the cleaning brush 3 along the length direction of the rotating shaft 4, and a connecting shaft 55 is fixedly arranged at both ends of the friction inclined plate 54 in the length direction. The two connecting shafts 55 are arranged in a colinear manner and parallel to the rotating shaft 4. One end of the connecting shaft 55 away from the friction inclined plate 54 is rotatably connected to the machine body 1. A reset torsion spring 56 is sleeved on each connecting shaft 55, and one end of the reset torsion spring 56 is connected to the friction inclined plate 54, and the other end is connected to the machine body 1. In a natural state, the bottom surface of the friction inclined plate 54 abuts against the supporting block 53 , and the friction inclined plate 54 and the cleaning brush 3 are spaced apart.

[0037] Reference Figure 1 and Figure 2 The cleaning brush 3 includes a rubber roller 33 and a brush layer 34 disposed outside the rubber roller 33, and the brush layer 34 can be unfolded into a plane. A plurality of connecting strips 35 are disposed parallel to the length direction of the cleaning brush 3 on the side of the brush layer 34 close to the rubber roller 33, and a plurality of connecting grooves 36 are disposed parallel to the length direction of the cleaning brush 3 on the outer ring wall of the rubber roller 33. The plurality of connecting grooves 36 are disposed one by one correspondingly to the plurality of connecting strips 35, and the connecting strips 35 are embedded in the corresponding connecting grooves 36. A material detection sensor 8 is disposed on the bottom surface of the body 1, and the material detection sensor 8 is electrically connected to the transmission motor 201.

[0038] Reference Figure 1 , Figure 2 and Figure 4When the vacuum cleaner is in use, the material detection sensor 8 detects the material of the ground and transmits the information to the transmission motor 201, which outputs a suitable speed. The transmission motor 201 drives the flywheel 202 to rotate. Since the flywheel 202 is pressed against the friction blocks 7 on the transmission pressure plate 203 in a natural state, the flywheel 202 can drive the transmission pressure plate 203 to rotate synchronously. The transmission pressure plate 203 is connected to the rotating shaft 4 through the linkage key 6 and the transmission key slot 2031, and the rotating shaft 4 rotates synchronously with the transmission pressure plate 203. The cleaning brush 3 rotates under the drive of the plug-in rods 10 arranged on the rotating shaft 4. Several support springs 11 simultaneously support the cleaning brush 3 internally, so that the cleaning brush 3 is kept coaxial with the rotating shaft 4 as much as possible. In addition, the influence of the deadweight of the cleaning brush 3 on the extrusion air chamber 210 is also reduced. When there is a bulge on the ground below the cleaning brush 3, the cleaning brush 3 moves relative to the rotating shaft 4. The inner wall of the central cavity 31 squeezes one of the extrusion air chambers 210 , and the gas enters the first cylinder 207 through the connecting branch pipe 209 , the connecting ring pipe 211 and the connecting header 208 .

[0039] Reference Figure 2 and Figure 4 , the output shaft of the first cylinder 207 is extended, the slip ring 206 is slightly displaced in the direction close to the transmission pressure plate 203, the slip ring 206 squeezes the spring plate 2042, and the spring plate 2042 moves in the direction away from the flywheel 202 under the limit of the mounting ring 205 and the squeezing action of the slip ring 206. The transmission pressure plate 203 is displaced along with the elastic ring, and the friction between the friction block 7 and the flywheel 202 is reduced, resulting in a reduction in the rotation speed of the cleaning brush 3, reducing the possibility of the raised ground being damaged under the cleaning of the cleaning brush 3 at a higher rotation speed. When the ground below the cleaning brush 3 is flat, the spring sheet 204 is installed to reset, and the friction block 7 on the transmission pressure plate 203 is again fitted with the flywheel 202 to achieve constant speed and stable transmission. Under the action of the installation spring sheet 204, the slip ring 206 slides in the opposite direction to achieve reset, and the gas in the first cylinder 207 flows back to the extrusion air chamber 210. Since the friction block 7 is connected to the transmission pressure plate 203 via the limiting frame 9, when the friction block 7 becomes thinner after long-term use, the limiting frame 9 can be removed and the friction block 7 can be replaced.

[0040] Reference Figure 3 and Figure 4When the rubber roller 33 squeezes the extrusion air chamber 210, the gas enters the second cylinder 52 through the gas hose 51, and the output shaft of the second cylinder 52 extends upward. The support block 53 pushes one side of the friction ramp 54 upward, and the friction ramp 54 rotates. The other side of the friction ramp 54 rotates downward and abuts against the cleaning brush 3 to generate relative friction, which helps to further reduce the rotation speed of the cleaning brush 3. When the ground is flat, the friction ramp 54 rotates in the opposite direction under the action of the reset torsion spring 56 to reset and separate from the cleaning brush 3 again.

[0041] Reference Figure 2 The brush layer 34 is detachably connected to the outside of the rubber roller 33 through a plurality of connecting strips 35. When in use, the brush layer 34 made of different materials can be installed on the outside of the rubber roller 33 according to the material of the ground.

[0042] The implementation principle of the brush structure of an intelligent induction vacuum cleaner in the embodiment of the present application is as follows: when the vacuum cleaner is used, the material detection sensor 8 detects the ground, and the transmission motor 201 outputs a suitable rotation speed. The transmission motor 201 drives the flywheel 202 and the transmission pressure plate 203 to rotate synchronously. When there is a bulge on the ground below the cleaning brush 3, the inner wall of the central cavity 31 squeezes the extrusion air chamber 210, and the gas enters the first cylinder 207.

[0043] The output shaft of the first cylinder 207 extends, the sliding ring 206 moves toward the direction close to the transmission pressure plate 203, the transmission pressure plate 203 moves along with the elastic ring, the friction between the friction block 7 and the flywheel 202 is reduced, resulting in a reduction in the rotation speed of the cleaning brush 3. At the same time, the gas enters the second cylinder 52, the second cylinder 52 pushes one side of the friction ramp 54 upward, and the other side of the friction ramp 54 rotates downward and abuts against the cleaning brush 3 to generate relative friction, which helps to further reduce the rotation speed of the cleaning brush 3.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
