The roller brush and the beating device are mounted on the housing, and the device also includes a drive mechanism that simultaneously drives the roller brush and the beating device. The drive mechanism can simultaneously drive the roller brush and the beating device to perform beating, but in actual operation, the beating device is prone to shaking. Utility Model Content

[0004] In view of this, the present invention provides a cleaning device to solve the problem of easy shaking of the tapping device.

[0005] This utility model provides a cleaning device, including:

[0006] Bottom shell;

[0007] The striking plate is movable up and down relative to the bottom shell, and the striking plate and the bottom shell are connected by a guide structure, which is used to guide the moving direction of the striking plate.

[0008] A roller brush assembly is rotatably mounted on the bottom shell;

[0009] The driving device drives the tapping plate to move up and down while simultaneously driving the roller brush assembly to rotate.

[0010] Beneficial effects: The drive unit moves the tapping plate up and down while simultaneously rotating the roller brush assembly, allowing the tapping plate and roller brush to tap simultaneously, improving cleaning efficiency. The tapping plate and the base shell cooperate through a guide structure, which guides the movement direction of the tapping plate. By setting the guide structure, the tapping plate can move smoothly in the up and down direction, preventing it from wobbling.

[0011] In one alternative implementation, the guide structure includes:

[0012] A guide post is provided in one of the bottom shell and the striking plate;

[0013] A guide hole is provided in one of the bottom shell and the beater plate, and the guide post is slidably engaged with the guide hole.

[0014] Beneficial effects: The guide post and guide hole work together to allow the beater plate to move smoothly in the up and down direction, preventing the beater plate from shaking.

[0015] In one optional embodiment, the bottom shell is provided with a striking plate chamber, which is movably disposed within the striking plate chamber.

[0016] Beneficial effects: By setting up a striking plate chamber, the striking plate is completely located inside the striking plate chamber when striking is not required, which can protect the striking plate. In addition, the striking plate chamber can limit and guide the up and down movement of the striking plate.

[0017] In one alternative embodiment, the circumferential surface of the striking plate is provided with a sealing strip, which seals against the circumferential wall of the striking plate chamber.

[0018] Beneficial effects: The sealing strip prevents dust from the cleaning surface from entering the beater chamber through the perimeter of the beater.

[0019] In one optional embodiment, the driving device includes:

[0020] A dual-axis output motor includes a first output shaft and a second output shaft. The first output shaft is connected to a first pulley. The striking plate is connected to the second output shaft through a transmission assembly, which can convert the rotation of the second output shaft into the movement of the striking plate.

[0021] A roller brush drive rod is connected to the roller brush assembly. The roller brush drive rod is connected to a second pulley, which is connected to the first pulley via a transmission belt.

[0022] Beneficial effects: When the dual-axis output motor is working, the first and second output shafts rotate synchronously. The rotation of the first output shaft drives the first pulley to rotate synchronously, which in turn drives the second pulley to rotate via a transmission belt. The second pulley drives the roller brush drive rod to rotate synchronously. The roller brush drive rod is connected to the roller brush assembly, thus driving the roller brush assembly to rotate within the roller brush mounting cavity. The transmission assembly converts the rotation of the second output shaft into the up-and-down movement of the striking plate within the striking plate cavity. Therefore, a single dual-axis output motor can simultaneously drive the striking plate and the rotation of the roller brush assembly. Furthermore, this drive device includes only one transmission belt, occupying less space.

[0023] In one alternative embodiment, the transmission assembly includes an eccentric wheel and a connecting rod. The eccentric wheel is fixed to the end of the second output shaft. A first end of the connecting rod is hinged to the eccentric wheel, and a second end of the connecting rod is hinged to the striking plate. The hinge axis between the connecting rod and the eccentric wheel is offset from the axis of the eccentric wheel.

[0024] Beneficial effects: The transmission assembly includes an eccentric wheel and a connecting rod. The eccentric wheel is fixed to the end of the second output shaft. Therefore, when the second output shaft rotates, it drives the eccentric wheel to rotate synchronously. Since the first end of the connecting rod is hinged to the eccentric wheel and the second end of the connecting rod is hinged to the striking plate, the hinge axis between the connecting rod and the eccentric wheel is offset from the rotation center of the eccentric wheel. Therefore, when the connecting rod rotates, it will move in the up and down direction, driving the striking plate to move up and down to achieve striking.

[0025] In one optional embodiment, the distance between the center of the hinge shaft and the axis of the eccentric wheel is X, where 1mm ≤ X ≤ 6mm.

[0026] In one optional embodiment, the first end of the connecting rod is provided with a first connecting hole, the first connecting hole is provided with a first bearing, the hinge shaft is provided on the eccentric wheel, and the inner ring of the first bearing is sleeved on the hinge shaft.

[0027] And / or, the second end of the connecting rod is provided with a second connecting hole, the second connecting hole is provided with a second bearing, the striking plate is provided with a hinge seat, and the fixing pin passes through the hinge seat and is fixed to the inner side of the inner ring of the second bearing.

[0028] Beneficial effects: The first connecting hole houses a first bearing, and the hinge shaft is located on the eccentric wheel. The inner ring of the first bearing is fitted onto the hinge shaft, ensuring smooth rotation of the first end of the connecting rod relative to the hinge shaft. The second connecting hole houses a second bearing, and the striking plate has a hinge seat. A fixing pin passes through the hinge seat and is fixed to the inner side of the inner ring of the second bearing, ensuring smooth rotation of the second end of the connecting rod relative to the hinge seat.

[0029] In one alternative embodiment, the drive device further includes a bracket, on which the motor is mounted, and the first output shaft and the roller brush drive rod are rotatably mounted on the bracket.

[0030] Beneficial effects: By setting up a bracket, the motor is mounted on the bracket, and the first output shaft and the roller brush drive rod can be rotatably mounted on the bracket. Therefore, the entire drive device can be assembled into a whole. Then, the whole is placed in the bottom shell, and the bracket is fixed to the bottom shell, thereby realizing the assembly of the entire drive device.

[0031] In one optional embodiment, the bracket includes a first limiting plate and a second limiting plate disposed opposite to each other, and a first end plate and a second end plate connecting the two ends of the first limiting plate and the second limiting plate. The first output shaft is rotatably disposed on the first end plate, and the motor is mounted on the second end plate and the second output shaft passes through the second end plate.

[0032] Beneficial effects: The first end plate provides limiting support for the first output shaft, while the second end plate serves both to fix the dual-shaft output motor and to provide limiting support for the second output shaft. Furthermore, the dual-shaft output motor is located between the first and second limiting plates, which provide protection and limit its movement.

[0033] In one alternative embodiment, the first end plate is fixed with a third bearing, which is sleeved outside the first output shaft.

[0034] Beneficial effects: The third bearing is sleeved outside the first output shaft and fixed to the first end plate, which can support and limit the first output shaft and ensure that the first output shaft rotates smoothly. Attached Figure Description

[0056] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0057] Cleaning equipment, such as mite removers, is a small household appliance with functions such as mite removal, vacuuming, and sterilization. It can clean dust off furniture such as beds and sofas. The core working principle of mite removers is "beating, vacuuming, and sterilization".

[0058] The related technology discloses a mite removal device, including a housing, a roller brush, and a beating device. The roller brush and the beating device are mounted on the housing, and the device also includes a drive mechanism that simultaneously drives the roller brush and the beating device. The drive mechanism can simultaneously drive the roller brush and the beating device to perform beating, but in actual operation, the beating device is prone to shaking.

[0059] The following is combined with Figures 1 to 14 The following describes embodiments of the present invention.

[0060] According to an embodiment of the present invention, a cleaning device is provided, comprising: a base shell 16, a tapping plate 7, a roller brush assembly 4, and a driving device.

[0061] The slapping plate 7 can be moved up and down relative to the bottom shell 16, and the slapping plate 7 and the bottom shell 16 are connected by a guide structure, which is used to guide the movement direction of the slapping plate 7; the roller brush assembly 4 is rotatably mounted on the bottom shell 16; the driving device drives the slapping plate 7 to move up and down while driving the roller brush assembly 4 to rotate.

[0062] In this embodiment, the driving device drives the tapping plate 7 to move up and down while simultaneously driving the roller brush assembly 4 to rotate. Therefore, the tapping plate 7 and the roller brush can tap simultaneously, improving cleaning efficiency. The tapping plate 7 and the bottom shell 16 cooperate through a guide structure, which guides the movement direction of the tapping plate 7. By setting the guide structure, the tapping plate 7 can move smoothly in the up and down direction, preventing the tapping plate 7 from shaking.

[0063] Specifically, during operation, the roller brush assembly 4 is located at the front of the machine. The roller brush rotates and taps the surface being cleaned, which can knock out dust mites from the surface and deep within the surface and then remove them.

[0064] In one embodiment, the cleaning device is a mite remover, which also includes an ultraviolet lamp assembly, an air duct assembly, a vacuum motor assembly, and a dust cup assembly.

[0065] Specifically in one embodiment, such as Figure 5 and Figure 10 As shown, the lower surface of the patting plate 7 is wavy, which can increase the patting effect.

[0066] In one embodiment, the guide structure includes a guide post 703 and a guide hole 1604. The guide post 703 is disposed in one of the bottom shell 16 and the beater plate 7; the guide hole 1604 is disposed in the other of the bottom shell 16 and the beater plate 7, and the guide post 703 and the guide hole 1604 are slidably engaged.

[0067] In this embodiment, the guide post 703 and the guide hole 1604 cooperate to allow the tapping plate 7 to move smoothly in the vertical direction, thus preventing the tapping plate 7 from shaking.

[0068] Specifically in one embodiment, such as Figures 10 to 12 The guide post 703 is located on the beater plate 7, and the guide hole 1604 is located on the bottom shell 16.

[0069] Specifically in one embodiment, such as Figure 9 , Figures 11 to 13 The bottom shell 16 is also provided with a roller brush chamber 1602, and the roller brush assembly 4 is located in the roller brush chamber 1602.

[0070] In one embodiment, the bottom shell 16 is provided with a striking plate chamber 1601, which is movably disposed in the striking plate chamber 1601.

[0071] In this embodiment, by providing a striking plate chamber 1601, the striking plate 7 is completely located within the striking plate chamber 1601 when striking is not required, which can protect the striking plate 7. Furthermore, the striking plate chamber 1601 can limit and guide the vertical movement of the striking plate 7.

[0072] In one specific embodiment, the striking plate chamber 1601 is provided with a through hole 1603 for the connecting rod 9 to pass through and move.

[0073] In one embodiment, the slapping plate 7 is provided with a sealing strip 15 in the circumferential direction, and the sealing strip 15 seals the circumferential wall of the slapping plate cavity 1601.

[0074] In this embodiment, the sealing strip 15 is provided to prevent dust from the cleaning surface from entering the tapping plate chamber 1601 through the periphery of the tapping plate 7.

[0075] The sealing strip 15 can be made of rubber, silicone, foamed rubber, felt, etc. It is preferred to use felt, which has the advantage of low frictional resistance and will not hinder the up and down movement of the beater 7.

[0076] In one embodiment, the circumference of the slapping plate 7 is provided with a mounting groove 702, and the sealing strip 15 is installed in the mounting groove 702.

[0077] In this embodiment, such as Figure 5 As shown, the installation groove 702 provided on the periphery of the tapping plate 7 facilitates the installation of the sealing strip 15.

[0078] In one embodiment, such as Figure 1 , Figures 4 to 8 The driving device includes a dual-axis output motor 1 and a roller brush drive rod 3. The dual-axis output motor 1 includes a first output shaft 101 and a second output shaft 102. The first output shaft 101 is connected to a first pulley 2. The striking plate 7 is connected to the second output shaft 102 through a transmission assembly, which can convert the rotation of the second output shaft 102 into the movement of the striking plate 7. The roller brush drive rod 3 is connected to a roller brush assembly 4 and is connected to a second pulley 5. The second pulley 5 is connected to the first pulley 2 through a transmission belt 6.

[0079] In this embodiment, when the dual-axis output motor 1 is working, the first output shaft 101 and the second output shaft 102 rotate synchronously. The rotation of the first output shaft 101 drives the first pulley 2 to rotate synchronously, which in turn drives the second pulley 5 to rotate via the transmission belt 6. The second pulley 5 drives the roller brush drive rod 3 to rotate synchronously. The roller brush drive rod 3 is connected to the roller brush assembly 4, thus driving the roller brush assembly 4 to rotate in the roller brush mounting cavity. The transmission assembly converts the rotation of the second output shaft 102 into the up-and-down movement of the striking plate 7 in the striking plate cavity 1601. Therefore, a single dual-axis output motor 1 can simultaneously drive the striking plate 7 to strike and the roller brush assembly 4 to rotate. Furthermore, this drive device only includes one transmission belt 6, thus occupying less space.

[0080] In one embodiment, the first pulley 2 is interference-fitted with the first output shaft 101.

[0081] In one embodiment, the first pulley 2 and the second pulley 5 are both gears, and both the first pulley 2 and the second pulley 5 mesh with the transmission belt 6.

[0082] In one embodiment, the outer diameter of the second pulley 5 is larger than the outer diameter of the first pulley 2. Since the outer diameter of the second pulley 5 is larger than the outer diameter of the first pulley 2, the rotation speed of the second pulley 5 will be lower than the rotation speed of the first pulley 2. Therefore, the rotation speed of the roller brush assembly 4 will be lower than the rotation speed of the first output shaft 101, thus avoiding the problems of hair entanglement, blanket rolling, and loud noise caused by the excessive rotation speed of the roller brush assembly 4.

[0083] In an alternative embodiment, such as Figure 14 As shown, the driving device may include a drive motor 1a, a third pulley 2a, a fourth pulley 3a, a fifth pulley 4a, and a roller brush drive rod 3. The output shaft of the drive motor 1a is equipped with the third pulley 2a; the fourth pulley 3a and the fifth pulley 4a are mounted on a connecting shaft 8a, and the fourth pulley 3a is connected to the third pulley 2a via a first conveyor belt; the roller brush drive rod 3 is adapted to connect to a roller brush, and the roller brush drive rod 3 is equipped with a sixth pulley 5a, which is connected to the fifth pulley 4a via a second conveyor belt 7a; the striking plate 7 is connected to the connecting shaft 8a via a transmission assembly, which can convert the rotation of the connecting shaft 8a into the movement of the striking plate 7. When the drive motor 1a is working, it drives the third pulley 2a to rotate. The third pulley 2a drives the fourth pulley 3a to rotate through the first transmission belt 6a. The fourth pulley 3a drives the fifth pulley 4a and the connecting shaft 8a to rotate synchronously. The connecting shaft 8a drives the beater 7 to move through the transmission assembly to achieve beating. The fifth pulley 4a drives the sixth pulley 5a to rotate through the second transmission belt 6, which in turn drives the roller brush drive rod 3 to rotate synchronously. The roller brush drive rod 3 drives the roller brush to rotate.

[0084] In one embodiment, the transmission assembly includes an eccentric wheel 8 and a connecting rod 9. The eccentric wheel 8 is fixed to the end of the second output shaft 102. The first end of the connecting rod 9 is hinged to the eccentric wheel 8, and the second end of the connecting rod 9 is hinged to the beater plate 7. The hinge axis 801 between the connecting rod 9 and the eccentric wheel 8 is offset from the axis 802 of the eccentric wheel 8.

[0085] In this embodiment, the transmission assembly includes an eccentric wheel 8 and a connecting rod 9. The eccentric wheel 8 is fixed to the end of the second output shaft 102. Therefore, when the second output shaft 102 rotates, it drives the eccentric wheel 8 to rotate synchronously. Since the first end of the connecting rod 9 is hinged to the eccentric wheel 8 and the second end of the connecting rod 9 is hinged to the striking plate 7, and the hinge axis 801 between the connecting rod 9 and the eccentric wheel 8 is offset from the rotation center of the eccentric wheel 8, the connecting rod 9 will move in the up and down direction while rotating, thereby driving the striking plate 7 to move up and down to achieve striking.

[0086] In one embodiment not shown in the figure, the transmission component may include a gear and rack, for example, a gear is connected to the end of the second output shaft 102, the gear meshes with the rack, the rack is connected to the striking plate 7, the rotation of the second output shaft 102 drives the gear to rotate, thereby driving the rack to move up and down, and the rack drives the striking plate 7 to move up and down to achieve striking.

The striking plate 7 is provided with a hinge seat 701, and the fixing pin 12 passes through the hinge seat 701 and is fixed to the inner side of the inner ring of the second bearing 11.

[0091] In this embodiment, a first bearing 10 is housed in the first connecting hole 901, and a hinge shaft 801 is mounted on the eccentric wheel 8. The inner ring of the first bearing 10 is fitted onto the hinge shaft 801, ensuring that the first end of the connecting rod 9 rotates smoothly relative to the hinge shaft 801. A second bearing 11 is housed in the second connecting hole 902, and a hinge seat 701 is provided on the striking plate 7. A fixing pin 12 passes through the hinge seat 701 and is fixed to the inner side of the inner ring of the second bearing 11, ensuring that the second end of the connecting rod 9 rotates smoothly relative to the hinge seat 701.

[0092] In a preferred embodiment, a first bearing 10 is provided between the first connecting hole 901 and the hinge shaft 801, and a second bearing 11 is provided between the second connecting hole 902 and the fixing pin 12.

[0093] In one embodiment not shown in the figure, the first bearing 10 and the second bearing 11 may not be provided.

[0096] In one embodiment, the drive device further includes a bracket 13, on which a motor is mounted, and on which both the first output shaft 101 and the brush drive rod 3 are rotatably mounted.

[0097] In this embodiment, by setting a bracket 13, the motor is mounted on the bracket 13, and the first output shaft 101 and the roller brush drive rod 3 are rotatably mounted on the bracket 13. Therefore, the entire drive device can be assembled into a whole, and then the whole is placed in the bottom shell 16, and the bracket 13 is fixed to the bottom shell 16, thereby realizing the assembly of the entire drive device.

[0098] In one embodiment, the bracket 13 includes a first limiting plate 1301 and a second limiting plate 1302 disposed opposite to each other, and a first end plate 1303 and a second end plate 1304 connecting the two ends of the first limiting plate 1301 and the second limiting plate 1302.

[0099] In this embodiment, the first end plate 1303 provides limiting support for the first output shaft 101, and the second end plate 1304 serves both to fix and support the dual-axis output motor 1 and to limit the second output shaft 102. The dual-axis output motor 1 is located between the first limiting plate 1301 and the second limiting plate 1302, which provide protection and limit the movement of the dual-axis output motor 1.
