Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a drive device, a tapping mechanism, and cleaning equipment. Background Technology

[0002] Cleaning devices such as mite removers are small household appliances that can remove mites, vacuum, and sterilize. They can clean dust from furniture such as beds and sofas. The core working principle of a mite remover is "beating, vacuuming, and sterilization." Mite removers include a roller brush, which has a beating function. The roller brush has advantages such as strong beating force and high frequency. However, when the roller brush rotates at high speed, it causes problems such as loud noise, hair entanglement, and curling up blankets. Reducing the speed of the roller brush can solve these problems to some extent, but it will also reduce the beating effect.

[0003] 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. The device also includes a drive unit that simultaneously drives the roller brush and the beating device. The drive unit includes a motor, a splined shaft, a first synchronous pulley, a second synchronous pulley, a synchronous belt, and an eccentric shaft. The power output end of the motor is connected to the splined shaft to output power. The splined shaft has a first spline and a second spline. The first spline is connected to the first synchronous pulley via a synchronous belt, and the second spline is connected to the second synchronous pulley via a synchronous belt. The first synchronous pulley drives the roller brush to rotate, and the second synchronous pulley drives the eccentric shaft to rotate. The beating device passes through the housing and is connected to the eccentric shaft. The rotation of the eccentric shaft causes the beating device to reciprocate relative to the housing.

[0004] The aforementioned technologies can drive both the roller brush and the beating device simultaneously with a single motor. However, the roller brush rotates at a high speed, resulting in loud noise, easy entanglement of hair, and tangling of blankets. If it is necessary to reduce the speed of the roller brush, the diameter of the gear connecting the roller brush needs to be increased, which increases the internal space occupied by the machine and leads to an increase in the overall size of the machine. Utility Model Content

[0005] In view of this, the present invention provides a driving device, a tapping mechanism and a cleaning device to solve the problem of high roller speed.

[0006] In a first aspect, this utility model provides a driving device, comprising:

[0007] The drive motor has a first pulley on its output shaft;

[0008] The second and third pulleys are mounted on the connecting shaft. The outer diameter of the second pulley is larger than the outer diameter of the third pulley. The second pulley is connected to the first pulley via a first conveyor belt.

[0009] A roller brush drive rod is adapted to connect to a roller brush assembly. The roller brush drive rod is provided with a fourth pulley. The outer diameter of the fourth pulley is larger than the outer diameter of the third pulley. The fourth pulley and the third pulley are connected by a second conveyor belt.

[0010] A transmission assembly, connected to the connecting shaft and adapted to be connected to the striking plate, is capable of converting the rotation of the connecting shaft into the movement of the striking plate.

[0011] Beneficial effects: When the drive motor is working, it drives the first pulley to rotate. The first pulley drives the second pulley to rotate via the first transmission belt. The second pulley drives the third pulley and the connecting shaft to rotate synchronously. The connecting shaft drives the beating plate to move via the transmission assembly to achieve beating. The third pulley drives the fourth pulley to rotate via the second transmission belt, which in turn drives the roller brush drive rod to rotate synchronously. The roller brush drive rod drives the roller brush assembly to rotate. A single drive motor can simultaneously drive the beating plate and the roller brush assembly to rotate. By making the outer diameter of the fourth pulley larger than that of the third pulley, and the speed of the fourth pulley lower than that of the third pulley, the second transmission belt can reduce the speed of the roller brush drive rod, resulting in low-speed rotation of the roller brush assembly. This avoids problems such as hair entanglement, blanket rolling, and excessive noise. Because the speed of the third pulley is higher than that of the fourth pulley, the connecting shaft can rotate at high speed, thereby achieving high-frequency beating of the beating plate. Furthermore, since the outer diameter of the second pulley is larger than that of the third pulley, and the outer diameter of the third pulley is smaller, the outer diameter of the fourth pulley does not need to be very large. Compared with related technologies, there is no need to increase the diameter of the gears connected to the roller brush assembly. Therefore, it is possible to reduce the speed of the roller brush assembly without increasing the space occupied.

[0012] In one alternative embodiment, the outer diameter of the second pulley is larger than the outer diameter of the first pulley.

[0013] Beneficial effects: Since the outer diameter of the second pulley is larger than that of the first pulley, the speed of the second pulley will be lower than that of the first pulley, and the speed of the connecting shaft will be lower than that of the motor, thus avoiding excessive noise caused by the excessive speed of the striking parts.

[0014] In one alternative embodiment, the second pulley and the third pulley are an integral structure.

[0015] Beneficial effects: The second and third pulleys are integrated into one structure, which reduces the number of parts and facilitates installation with the connecting shaft.

[0016] In one optional embodiment, the first pulley and the second pulley are gears, and the first pulley and the second pulley mesh with the first conveyor belt;

[0017] And / or, the third pulley and the fourth pulley are gears, and the third pulley and the fourth pulley mesh with the second conveyor belt.

[0018] Beneficial effects: The first and second pulleys are gears, meshing with the first conveyor belt to ensure no slippage between them and the conveyor belt, thus ensuring transmission efficiency. The third and fourth pulleys are also gears, meshing with the second conveyor belt to ensure no slippage between them and the second conveyor belt, thus ensuring transmission efficiency.

[0019] In one alternative embodiment, the drive device further includes a bracket adapted to be fixedly installed inside the housing of the cleaning equipment, the drive motor is mounted on the bracket, and the connecting shaft and the roller brush drive rod are rotatably mounted on the bracket.

[0020] Beneficial effects: By setting up a bracket, the drive motor is mounted on the bracket, and the connecting shaft and the roller brush drive rod can be rotatably set on the bracket. Therefore, the entire drive device can be assembled into a whole component. Then, the whole component is placed in the housing, and the bracket is fixed to the housing, thereby realizing the assembly of the entire drive device.

[0021] In one optional embodiment, the bracket includes a first limiting plate and a second limiting plate disposed opposite to each other, and two end plates connecting the first limiting plate and the second limiting plate. The end plates are provided with limiting holes, and the connecting shaft is disposed between the first limiting plate and the second limiting plate and is rotatably disposed in the limiting holes.

[0022] Beneficial effects: The connecting shaft is located between the first limiting plate and the second limiting plate, and is rotatably located in the limiting hole. The two limiting holes can support and limit the connecting shaft, ensuring that the connecting shaft can rotate smoothly.

[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 connecting 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 rotation center 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 connecting shaft. Therefore, when the connecting 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 eccentric wheel is provided with a non-circular connecting hole, and the end of the connecting shaft away from the second pulley is provided with a plug-in portion, the shape of which is consistent with the connecting hole, and the plug-in portion is plugged into the connecting hole.

[0026] Beneficial effects: By setting a non-circular connecting hole on the eccentric wheel, and providing an insertion part at the end of the connecting shaft away from the second pulley, the shape of the insertion part is consistent with the connecting hole. The insertion part is inserted into the connecting hole, which facilitates the quick connection between the eccentric wheel and the connecting shaft and ensures that the connecting shaft drives the eccentric wheel to rotate.

[0027] In one alternative embodiment, the striking plate is provided with a hinge seat, and the second end of the connecting rod is adapted to be hinged to the hinge seat by a fixing pin.

[0028] Beneficial effects: The fixing pin can connect the second end of the connecting rod to the hinge seat, and the connecting rod can rotate relative to the hinge seat.

[0029] Secondly, this utility model also provides a slapping mechanism, including: the aforementioned driving device, as well as a roller brush assembly and a slapping plate, wherein the roller brush driving rod is connected to the roller brush assembly, and the transmission assembly is connected to the slapping plate.

[0030] Beneficial effects: When the drive motor is working, it drives the first pulley to rotate. The first pulley drives the second pulley to rotate via the first transmission belt. The second pulley drives the third pulley and the connecting shaft to rotate synchronously. The connecting shaft drives the beating plate to move via the transmission assembly to achieve beating. The third pulley drives the fourth pulley to rotate via the second transmission belt, which in turn drives the roller brush drive rod to rotate synchronously. The roller brush drive rod drives the roller brush assembly to rotate. A single drive motor can simultaneously drive the beating plate and the roller brush assembly to rotate. By making the outer diameter of the fourth pulley larger than that of the third pulley, and the speed of the fourth pulley lower than that of the third pulley, the second transmission belt can reduce the speed of the roller brush drive rod, resulting in low-speed rotation of the roller brush assembly. This avoids problems such as hair entanglement, blanket rolling, and excessive noise. Because the speed of the third pulley is higher than that of the fourth pulley, the connecting shaft can rotate at high speed, thereby achieving high-frequency beating of the beating plate. Furthermore, since the outer diameter of the second pulley is larger than that of the third pulley, and the outer diameter of the third pulley is smaller, the outer diameter of the fourth pulley does not need to be very large. Compared with related technologies, there is no need to increase the diameter of the gears connected to the roller brush assembly. Therefore, it is possible to reduce the speed of the roller brush assembly without increasing the space occupied.

[0031] Thirdly, this utility model also provides a cleaning device, comprising:

[0032] The housing has a mounting groove at its bottom and a roller brush mounting cavity, in which the roller brush assembly is located;

[0033] The striking mechanism is located inside the housing, and the striking plate is movably disposed above and below the mounting groove, and is adapted to extend out of the housing under the drive of the transmission assembly.

[0034] Beneficial effects: When the drive motor is working, it drives the first pulley to rotate. The first pulley drives the second pulley to rotate via the first transmission belt. The second pulley drives the third pulley and the connecting shaft to rotate synchronously. The connecting shaft drives the striking plate to move up and down in the mounting slot through the transmission assembly to achieve striking. The third pulley drives the fourth pulley to rotate via the second transmission belt, which in turn drives the roller brush drive rod to rotate synchronously. The roller brush drive rod drives the roller brush assembly to rotate in the roller brush mounting cavity. A single drive motor can simultaneously drive the striking plate to strike and the roller brush assembly to rotate. By making the outer diameter of the fourth pulley larger than that of the third pulley, and the speed of the fourth pulley lower than that of the third pulley, the second transmission belt reduces the speed of the roller brush drive rod, resulting in low-speed rotation of the roller brush assembly. This avoids problems such as hair entanglement, blanket rolling, and excessive noise. Because the speed of the third pulley is higher than that of the fourth pulley, the connecting shaft can rotate at high speed, thereby achieving high-frequency striking of the striking plate. Furthermore, since the outer diameter of the second pulley is larger than that of the third pulley, and the outer diameter of the third pulley is smaller, the outer diameter of the fourth pulley does not need to be very large. Compared with related technologies, there is no need to increase the diameter of the gears connecting the roller brush. Therefore, it is possible to reduce the speed of the roller brush assembly without increasing the space occupied. Thus, this cleaning device can reduce the speed of the roller brush assembly without increasing its size. Attached Figure Description

Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0049] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0050] 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.

[0051] 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. The device also includes a drive unit that simultaneously drives the roller brush and the beating device. The drive unit includes a motor, a splined shaft, a first synchronous pulley, a second synchronous pulley, a synchronous belt, and an eccentric shaft. The power output end of the motor is connected to the splined shaft to output power. The splined shaft has a first spline and a second spline. The first spline is connected to the first synchronous pulley via a synchronous belt, and the second spline is connected to the second synchronous pulley via a synchronous belt. The first synchronous pulley drives the roller brush to rotate, and the second synchronous pulley drives the eccentric shaft to rotate. The beating device passes through the housing and is connected to the eccentric shaft. The rotation of the eccentric shaft causes the beating device to reciprocate relative to the housing.

[0052] The aforementioned technologies can drive both the roller brush and the beating device simultaneously with a single motor. However, the roller brush rotates at a high speed, resulting in loud noise, easy entanglement of hair, and tangling of blankets. If it is necessary to reduce the speed of the roller brush, the diameter of the gear connecting the roller brush needs to be increased, which increases the internal space occupied by the machine and leads to an increase in the overall size of the machine.

[0053] The following is combined Figures 1 to 9 The following describes embodiments of the present invention.

[0054] According to an embodiment of the present invention, in a first aspect, a driving device is provided, comprising: a drive motor 1, a first pulley 2, a second pulley 3 and a third pulley 4, a roller brush drive rod 6 and a transmission assembly.

[0055] The drive motor 1 has a first pulley 2 on its output shaft; a second pulley 3 and a third pulley 4 are mounted on a connecting shaft 8, the outer diameter of the second pulley 3 is larger than the outer diameter of the third pulley 4, and the second pulley 3 is connected to the first pulley 2 via a first conveyor belt 9; a roller brush drive rod 6 is adapted to connect to a roller brush assembly 18, and the roller brush drive rod 6 has a fourth pulley 5, the outer diameter of the fourth pulley 5 is larger than the outer diameter of the third pulley 4, and the fourth pulley 5 is connected to the third pulley 4 via a second conveyor belt 10; a transmission assembly is connected to the connecting shaft 8 and adapted to connect to a striking plate 7, and the transmission assembly can convert the rotation of the connecting shaft 8 into the movement of the striking plate 7.

[0056] In this embodiment, when the drive motor 1 is working, it drives the first pulley 2 to rotate. The first pulley 2 drives the second pulley 3 to rotate via the first transmission belt. The second pulley 3 drives the third pulley 4 and the connecting shaft 8 to rotate synchronously. The connecting shaft 8 drives the patting plate 7 to move via the transmission assembly to achieve patting. The third pulley 4 drives the fourth pulley 5 to rotate via the second transmission belt, which in turn drives the roller brush drive rod 6 to rotate synchronously. The roller brush drive rod 6 drives the roller brush assembly 18 to rotate. One drive motor 1 can simultaneously drive the patting plate 7 to pat and the roller brush assembly 18 to rotate. By making the outer diameter of the fourth pulley 5 larger than that of the third pulley 4, the rotation speed of the fourth pulley 5 is lower than that of the third pulley 4. The second transmission belt 10 reduces the rotation speed, which can reduce the speed of the roller brush drive rod 6 and make the roller brush assembly 18 rotate at a low speed, thus avoiding problems such as hair entanglement, blanket rolling, and excessive noise. Since the rotation speed of the third pulley 4 is higher than that of the fourth pulley 5, the connecting shaft 8 can rotate at high speed, thereby achieving high-frequency patting of the patting plate 7. Furthermore, since the outer diameter of the second pulley 3 is larger than that of the third pulley 4, and the outer diameter of the third pulley 4 is smaller, the outer diameter of the fourth pulley 5 does not need to be very large. Compared with related technologies, there is no need to increase the diameter of the gear connected to the roller brush assembly 18. Therefore, it is possible to reduce the speed of the roller brush assembly 18 without increasing the space occupied.

[0057] Specifically in one embodiment, such as Figure 3 As shown, the lower surface of the patting plate 7 is wavy, which can increase the patting effect.

[0058] In one embodiment, the outer diameter of the second pulley 3 is larger than the outer diameter of the first pulley 2.

[0059] In this embodiment, since the outer diameter of the second pulley 3 is larger than that of the first pulley 2, the rotational speed of the second pulley 3 will be lower than that of the first pulley 2, and the rotational speed of the connecting shaft 8 will be lower than that of the motor, so as to avoid excessive noise caused by excessively high speed of the striking parts.

[0060] In one embodiment, the second pulley 3 and the third pulley 4 are an integral structure.

[0061] In this embodiment, the second pulley 3 and the third pulley 4 are an integral structure, which can reduce the number of parts and facilitate installation with the connecting shaft 8.

[0062] Specifically, such as Figure 4 As shown, the second pulley 3 has a first mounting hole 301 at its center. The first mounting hole 301 is interference-fitted with the connecting shaft 8 to fix the second pulley 3 and the third pulley 4 at one end of the connecting shaft 8.

[0063] In one embodiment, the first pulley 2 and the second pulley 3 are gears, and the first pulley 2 and the second pulley 3 mesh with the first conveyor belt 9; and / or, the third pulley 4 and the fourth pulley 5 are gears, and the third pulley 4 and the fourth pulley 5 mesh with the second conveyor belt 10.

[0064] In this embodiment, the first pulley 2 and the second pulley 3 are gears, and they mesh with the first conveyor belt 9 to ensure no slippage between them and the first conveyor belt 9, thus ensuring transmission efficiency. The third pulley 4 and the fourth pulley 5 are gears, and they mesh with the second conveyor belt 10 to ensure no slippage between them and the second conveyor belt 10, thus ensuring transmission efficiency.

[0065] In one specific embodiment, the first pulley 2, the second pulley 3, the third pulley 4, and the fourth pulley 5 are all gears.

[0066] In one embodiment not shown in the figure, the first pulley 2, the second pulley 3, the third pulley 4, and the fourth pulley 5 are all friction wheels.

[0067] In one embodiment, the drive device further includes a bracket 11, which is adapted to be fixedly installed inside the housing 17 of the cleaning equipment. The drive motor 1 is mounted on the bracket 11, and the connecting shaft 8 and the roller brush drive rod 6 are rotatably mounted on the bracket 11.

[0068] In this embodiment, by setting a bracket 11, the drive motor 1 is mounted on the bracket 11, and the connecting shaft 8 and the roller brush drive rod 6 are rotatably set on the bracket 11. Therefore, the entire drive device can be assembled into an integral component. Then, the integral component is placed in the housing 17, and the bracket 11 is fixed to the housing 17, thereby realizing the assembly of the entire drive device.

[0069] In one embodiment, the bracket 11 includes a first limiting plate 1101 and a second limiting plate 1102 disposed opposite to each other, and two end plates 1103 connecting the first limiting plate 1101 and the second limiting plate 1102. The end plates 1103 are provided with limiting holes, and the connecting shaft 8 is disposed between the first limiting plate 1101 and the second limiting plate 1102 and is rotatably disposed in the limiting holes.

[0070] In this embodiment, the connecting shaft 8 is located between the first limiting plate 1101 and the second limiting plate 1102, and is rotatably located in the limiting hole. The two limiting holes can support and limit the connecting shaft 8, ensuring that the connecting shaft 8 can rotate smoothly.

[0071] In a preferred embodiment, a bearing 12 is provided between the connecting shaft 8 and the limiting hole, and the bearing 12 can make the connecting shaft 8 rotate smoothly relative to the bracket 11.

[0072] In one embodiment, such as Figure 2 As shown, the bracket 11 also includes a first mounting part 1104 located on one side of the first limiting plate 1101 and a second mounting part 1105 located on one side of the second limiting plate 1102. The first mounting part 1104 is flush with one of the end plates 1103, and the second mounting part 1105 protrudes from the end plate 1103. The first mounting part 1104 is used to mount the drive motor 1, and the second mounting part 1105 is used to mount the roller brush drive rod 6.

[0073] In one embodiment, the transmission assembly includes an eccentric wheel 13 and a connecting rod 14. The eccentric wheel 13 is fixed to the end of the connecting shaft 8. The first end of the connecting rod 14 is hinged to the eccentric wheel 13, and the second end of the connecting rod 14 is hinged to the striking plate 7. The hinge axis between the connecting rod 14 and the eccentric wheel 13 is offset from the center of the eccentric wheel 13.

[0074] In this embodiment, the transmission assembly includes an eccentric wheel 13 and a connecting rod 14. The eccentric wheel 13 is fixed to the end of the connecting shaft 8. Therefore, when the connecting shaft 8 rotates, it drives the eccentric wheel 13 to rotate synchronously. Since the first end of the connecting rod 14 is hinged to the eccentric wheel 13 and the second end of the connecting rod 14 is hinged to the striking plate 7, the hinge axis between the connecting rod 14 and the eccentric wheel 13 is offset from the rotation center of the eccentric wheel 13. Therefore, when the connecting rod 14 rotates, it will move in the up and down direction, driving the striking plate 7 to move up and down to achieve striking.

[0075] In a preferred embodiment, the eccentric wheel 13 is provided with a hinge shaft, the first end of the connecting rod 14 is provided with a second mounting hole, and a bearing 12 is provided between the second mounting hole and the hinge shaft.

[0076] 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 connecting shaft 8, the gear meshes with the rack, the rack is connected to the striking plate 7, the rotation of the connecting shaft 8 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.

[0077] In one embodiment, the eccentric wheel 13 is provided with a non-circular connecting hole 1301, and the end of the connecting shaft 8 away from the second pulley 3 is provided with a plug-in part. The shape of the plug-in part is consistent with the connecting hole 1301, and the plug-in part is plugged into the connecting hole 1301.

[0078] In this embodiment, by providing a non-circular connecting hole 1301 on the eccentric wheel 13, and providing an insertion part at the end of the connecting shaft 8 away from the second pulley 3, the shape of the insertion part is consistent with the connecting hole 1301. The insertion part is inserted into the connecting hole 1301, which facilitates the quick connection between the eccentric wheel 13 and the connecting shaft 8, and ensures that the connecting shaft 8 drives the eccentric wheel 13 to rotate.

[0079] In one specific embodiment, the connection hole 1301 can be various shapes such as semi-circular, rectangular, or triangular.

[0080] In one specific embodiment, the side wall of the eccentric wheel 13 is provided with a locking hole 1302, which is connected to the connecting hole 1301. When the end of the connecting shaft 8 is inserted into the connecting hole 1301, the locking member 15 is inserted through the locking hole 1302, and the locking member 15 abuts against the insertion part to lock the insertion part.

[0081] In one embodiment, the striking plate 7 is provided with a hinge seat 701, and the second end of the connecting rod 14 is adapted to be hinged to the hinge seat 701 by a fixing pin 16.

[0082] In this embodiment, the fixing pin 16 can connect the second end of the connecting rod 14 to the hinge seat 701, and the connecting rod 14 can rotate relative to the hinge seat 701.

[0083] In one specific embodiment, the second end of the connecting rod 14 is provided with a third mounting hole, and a bearing 12 is provided between the third mounting hole and the fixing pin 16.

[0084] In one specific embodiment, the hinge seat 701 is provided with a through hole, and the fixing pin 16 passes through the through hole and the third mounting hole and is fixed by a screw.

[0085] According to an embodiment of the present invention, in a second aspect, a slapping mechanism is also provided, comprising: the driving device provided in the above embodiment, a roller brush assembly 18 and a slapping plate 7, wherein a roller brush drive rod 6 is connected to the roller brush assembly 18, and a transmission assembly is connected to the slapping plate 7.

[0086] When drive motor 1 is working, it drives the first pulley 2 to rotate. The first pulley 2 drives the second pulley 3 to rotate via the first transmission belt. The second pulley 3 drives the third pulley 4 and the connecting shaft 8 to rotate synchronously. The connecting shaft 8 drives the patting plate 7 to move via the transmission assembly to achieve patting. The third pulley 4 drives the fourth pulley 5 to rotate via the second transmission belt, which in turn drives the roller brush drive rod 6 to rotate synchronously. The roller brush drive rod 6 drives the roller brush assembly 18 to rotate. One drive motor 1 can simultaneously drive the patting plate 7 to pat and the roller brush assembly 18 to rotate. By making the outer diameter of the fourth pulley 5 larger than that of the third pulley 4, the rotation speed of the fourth pulley 5 is lower than that of the third pulley 4. The second transmission belt 10 reduces the rotation speed, which can reduce the speed of the roller brush drive rod 6 and make the roller brush assembly 18 rotate at a low speed, thus avoiding problems such as hair entanglement, blanket rolling, and excessive noise. Since the rotation speed of the third pulley 4 is higher than that of the fourth pulley 5, the connecting shaft 8 can rotate at high speed, thereby achieving high-frequency patting of the patting plate 7. Furthermore, since the outer diameter of the second pulley 3 is larger than that of the third pulley 4, and the outer diameter of the third pulley 4 is smaller, the outer diameter of the fourth pulley 5 does not need to be very large. Compared with related technologies, there is no need to increase the diameter of the gear connected to the roller brush assembly 18. Therefore, it is possible to reduce the speed of the roller brush assembly 18 without increasing the space occupied.

[0087] According to an embodiment of the present invention, in a third aspect, a cleaning device is also provided, comprising: a housing 17 and a tapping mechanism provided in the above embodiment.

[0088] The bottom of the housing 17 is provided with a mounting groove 1702, the housing 17 is provided with a roller brush mounting cavity, and the roller brush assembly 18 is provided in the roller brush mounting cavity; the slapping mechanism is provided in the housing 17, and the slapping plate 7 is movably provided in the mounting groove 1702 and is adapted to extend out of the housing 17 under the drive of the transmission assembly.

[0089] In this embodiment, when the drive motor 1 is working, it drives the first pulley 2 to rotate. The first pulley 2 drives the second pulley 3 to rotate via the first transmission belt. The second pulley 3 drives the third pulley 4 and the connecting shaft 8 to rotate synchronously. The connecting shaft 8 drives the patting plate 7 to move up and down in the mounting groove 1702 via the transmission assembly to achieve patting. The third pulley 4 drives the fourth pulley 5 to rotate via the second transmission belt, which in turn drives the roller brush drive rod 6 to rotate synchronously. The roller brush drive rod 6 drives the roller brush assembly 18 to rotate in the roller brush mounting cavity. One drive motor 1 can simultaneously drive the patting plate 7 to pat and the roller brush assembly 18 to rotate. By making the outer diameter of the fourth pulley 5 larger than that of the third pulley 4, the rotation speed of the fourth pulley 5 is lower than that of the third pulley 4. The second conveyor belt 10 reduces the speed of the transmission, which can reduce the speed of the roller brush drive rod 6 and make the roller brush assembly 18 rotate at a low speed, thus avoiding problems such as hair entanglement, blanket rolling, and high noise. Since the rotation speed of the third pulley 4 is higher than that of the fourth pulley 5, the connecting shaft 8 can rotate at high speed, thereby achieving high-frequency patting of the patting plate 7. Furthermore, since the outer diameter of the second pulley 3 is larger than that of the third pulley 4, and the outer diameter of the third pulley 4 is smaller, the outer diameter of the fourth pulley 5 does not need to be very large. Compared with related technologies, there is no need to increase the diameter of the gear connected to the roller brush assembly 18. Therefore, the speed reduction of the roller brush assembly 18 can be achieved without increasing the space occupied. Thus, this cleaning device can achieve speed reduction of the roller brush assembly 18 without increasing its size.

[0090] In operation, the roller brush assembly 18 is located at the front of the machine. The roller brush assembly 18 rotates to beat the surface being cleaned, which can knock out dust mites from the surface and deep inside the surface and then remove them.

[0091] In one embodiment, the cleaning device is a mite remover, and also includes an ultraviolet lamp assembly 19, an air duct assembly 20, a vacuum motor assembly 21, and a dust cup assembly 22. The housing 17 includes a bottom housing 1701, and the drive unit is mounted on the bottom housing 1701.

[0092] In one embodiment, the striking plate 7 and the housing 17 are connected by a guide structure, which is used to guide the movement direction of the striking plate 7.

[0093] In one specific embodiment, the guide structure includes a guide post 702 and a guide hole. The guide post 702 is disposed on the beater plate 7, and the guide hole is disposed on the bottom shell 1701. The guide post 702 and the guide hole are slidably engaged.

[0094] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
