Description

Technical Field

[0001] This invention relates to the field of vacuum cleaner technology, and more specifically, to a dust removal mechanism, a dust collection station having the dust removal mechanism, and a vacuum cleaner having the dust collection station. Background Technology

[0002] After using a handheld vacuum cleaner, the dust cup or dust bag needs to be removed to clean the dust inside. During cleaning, the dust will be scattered into the air, causing secondary pollution. Direct contact with dust also reduces the user experience. Dust collection stations can realize the function of automatically cleaning dust, reducing the frequency of dust cleaning and improving the hygiene environment and user experience.

[0003] In related technologies, dust collection stations typically employ a cam-push-rod mechanism for dust removal, driven by a motor and a gear set. The cam then drives the push rod up and down. However, during the movement of this cam-push-rod mechanism, the force generated by the push rod varies over time, resulting in low driving force. Furthermore, the mechanism exhibits poor stability, with significant vertical deformation of the push rod during movement, leading to high noise levels. Additionally, this mechanism limits the opening angle of the dust cup cover during dust removal, resulting in limited cleaning capacity. Moreover, the mechanism occupies a large amount of space.

Detailed Implementation

[0030] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The cleaning mechanism 10 according to a first aspect of the present invention will now be described with reference to the accompanying drawings.

[0032] like Figures 1-5 As shown, the dust removal mechanism 10 according to an embodiment of the present invention includes: a frame 100, a transmission assembly and a push plate 400.

[0033] Specifically, the transmission assembly is rotatably mounted on the frame 100 and has multiple meshing teeth 11. The push plate 400 is movable between a rising position and a falling position, and the push plate 400 has a rack 401. The multiple meshing teeth 11 mesh with the rack 401 to achieve the upward movement of the push plate 400. The distribution circle of the multiple meshing teeth 11 has a notch 12 to achieve the instantaneous jumping action of the push plate 400. That is, the multiple meshing teeth 11 of the transmission assembly are distributed on the same circumference, but the multiple meshing teeth 11 are not distributed around the entire circumference. A certain interval is defined between the first and last meshing teeth 11 in the circumferential direction to form a notch 12. When the transmission assembly rotates to the point where the notch 12 is opposite to the rack 401, the instantaneous jumping action of the push plate 400 is achieved.

[0034] Therefore, the dust removal mechanism 10 according to the embodiment of the present invention solves the problem of time-varying driving force through the meshing transmission mechanism, thereby generating a stable and large thrust; and it can reduce the structural load, reduce the deformation of the motion mechanism, and reduce noise; the tooth meshing drive makes the motion process smooth and the stroke large, which increases the opening angle of the cup lid 20 and improves the dust removal capability; in addition, the structure is compact and can reduce the structural volume.

[0035] The cleaning mechanism 10 according to some specific embodiments of the present invention is described below with reference to the accompanying drawings.

[0036] like Figures 1-5 As shown, the transmission assembly includes a first transmission assembly 200 and a second transmission assembly 300. That is, the dust removal mechanism 10 according to the embodiment of the present invention includes: a frame 100, a first transmission assembly 200, a second transmission assembly 300, and a push plate 400.

[0037] Specifically, the first transmission assembly 200 and the second transmission assembly 300 are rotatably mounted on the frame 100, and the first transmission assembly 200 and the second transmission assembly 300 mesh with each other. The push plate 400 is movable between a rising position and a falling position, and the push plate 400 is provided with a rack 401. The first transmission assembly 200 and the second transmission assembly 300 are each provided with a plurality of meshing teeth 11. The plurality of meshing teeth 11 of the first transmission assembly 200 and the plurality of meshing teeth 11 of the second transmission assembly 300 mesh with the rack 401 to realize the upward movement of the push plate 400. Among them, the distribution circle of the plurality of meshing teeth 11 is provided with a notch 12 to realize the instantaneous jumping action of the push plate 400. In other words, the multiple meshing teeth 11 of the first transmission component 200 are distributed on the same circumference, and the multiple meshing teeth 11 are not distributed on the entire circumference. A certain interval is defined between the first and last meshing teeth 11 in the circumferential direction to form a notch 12. The multiple meshing teeth 11 of the second transmission component 300 are distributed on the same circumference, and the multiple meshing teeth 11 are not distributed on the entire circumference. A certain interval is defined between the first and last meshing teeth 11 in the circumferential direction to form a notch 12. When the first transmission component 200 and the second transmission component 300 rotate to the point where the notch 12 is opposite to the rack 401, the instantaneous jump action of the push plate 400 is realized.

[0038] The stroke of the push plate 400 is related to the diameter of the circle where the notch 12 is located. For example, the stroke of the push plate 400 is the circumference of the distribution circle of the multiple meshing teeth 11.

[0039] Therefore, the dust removal mechanism 10 according to the embodiment of the present invention solves the problem of time-varying driving force through the meshing transmission mechanism, thereby generating a stable and large thrust; and it can reduce structural load, reduce deformation of the motion mechanism, and reduce noise; the dual meshing drive makes the motion process smooth and the stroke large, which increases the opening angle of the cup lid 20 and improves the dust removal capability; in addition, the structure is compact and can reduce the structural volume.

[0040] In some embodiments of the present invention, such as Figure 2 As shown, racks 401 are respectively provided on opposite sides of the push plate 400, and multiple meshing teeth 11 of the first transmission component 200 and multiple meshing teeth 11 of the second transmission component 300 are respectively located on opposite sides of the push plate 400. In this way, the center line of the push plate 400 is located between the first transmission component 200 and the second transmission component 300, resulting in smoother transmission, less deformation, and lower noise.

[0041] In some specific embodiments of the present invention, such as Figure 1As shown, the push plate 400 is provided with a limiting structure 402, which cooperates with at least one of the first transmission assembly 200 and the second transmission assembly 300 to limit the push plate 400 when it falls. For example, there are two limiting structures 402, which cooperate with the first transmission assembly 200 and the second transmission assembly 300 respectively. In this way, after the push plate 400 jumps, its lowest position can be limited. The limiting structure 402 can be a downward-opening arc-shaped groove.

[0042] According to some embodiments of the present invention, the dust removal mechanism 10 further includes an elastic element connected to the push plate 400. The elastic element drives the push plate 400 to a normally falling position; that is, the elastic element has a force that pushes the push plate 400 to the normally falling position, thereby increasing the falling speed of the push plate 400 and increasing the stability of the structure. For example, the elastic element can be a spring, thus resulting in a simple structure and good elasticity. According to some embodiments of the present invention, such as... Figure 1 and Figure 2 As shown, the transmission center line of the first transmission component 200 is parallel to the transmission center line of the second transmission component 300, thus ensuring smooth transmission and a compact structure.

[0043] According to some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the dust removal mechanism 10 further includes a drive assembly 500, which is disposed on the frame 100 and is drive-connected to one of the first transmission assembly 200 and the second transmission assembly 300, thereby driving the motion mechanism. For example, the drive assembly 500 is drive-connected to the first transmission assembly 200, and the first transmission assembly 200 drives the second transmission assembly 300 to rotate through engagement with the second transmission assembly 300.

[0044] In some specific embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the drive assembly 500 includes a drive device 510 and a drive gear set 520. The input end of the drive gear set 520 is connected to the drive device 510, and the output end of the drive gear set 520 is connected to one of the first transmission assembly 200 and the second transmission assembly 300. For example, the drive device 510 is a motor, and the drive gear set 520 includes a first drive gear 521, a transition gear 522, and a second drive gear 523. The first drive gear 521 is connected to the motor, and the first drive gear 521 meshes with the transition gear 522 to drive the second drive gear 523 to rotate. The second drive gear 523 meshes with the first transmission assembly 200 to drive the first drive assembly 500 to rotate.

[0045] According to some embodiments of the present invention, such as Figures 1-5As shown, the transmission assembly includes a transmission shaft, a transmission gear, and a follower gear. The transmission shaft is rotatably mounted on the frame 100. The transmission gear is sleeved on the transmission shaft. The follower gear is sleeved on the transmission shaft and has multiple meshing teeth 11. The follower gear is constructed in a chamfered shape. The follower gear can be a rubber chamfered wheel, and its surface is textured to increase friction. The mating surface of the rack 401 can also be textured. Furthermore, the opening angle of the follower gear is related to the stroke and dimensions of the push plate 400, and the size of the chamfer 12 can be adjusted according to the stroke and dimensions of the push plate 400.

[0046] Specifically, such as Figure 1 and Figure 2 As shown, the first transmission assembly 200 includes a first transmission shaft 210, a first transmission gear 220, and a first follower gear 230. The first transmission shaft 210 is rotatably mounted on the frame 100. The first transmission gear 220 is sleeved on the first transmission shaft 210 and meshes with the second transmission assembly 300. The first follower gear 230 is sleeved on the first transmission shaft 210 and has multiple meshing teeth 11. The first follower gear 230 is constructed in a segmental shape.

[0047] Specifically, such as Figure 1 and Figure 2 As shown, the second transmission assembly 300 includes a second transmission shaft 310, a second transmission gear 320, and a second follower gear 330. The second transmission shaft 310 is rotatably mounted on the frame 100. The second transmission gear 320 is sleeved on the second transmission shaft 310 and meshes with the first transmission assembly 200. The second follower gear 330 is sleeved on the second transmission shaft 310 and has multiple meshing teeth 11. The second follower gear 330 is constructed in a segmental shape.

[0048] According to a specific embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the first drive gear 521 is connected to the motor drive. The first drive gear 521 meshes with the transition gear 522 to drive the second drive gear 523 to rotate. The second drive gear 523 meshes with the first transmission gear 220 to drive the first transmission shaft 210 to rotate. The first transmission shaft 210 drives the first follower gear 230 to rotate. Multiple meshing teeth 11 on the first follower gear 230 mesh with the rack 401 on one side of the push plate 400. At the same time, the first transmission gear 220 meshes with the second transmission gear 320 to drive the second transmission shaft 310 to rotate. The second transmission shaft 310 drives the second follower gear 330 to rotate. Multiple meshing teeth 11 on the second follower gear 330 mesh with the rack 401 on the other side of the push plate 400. Thus, the push plate 400 is pushed upward to the rising position from the opposite sides of the push plate 400.

[0049] The first follower gear 230 and the second follower gear 330 are respectively constructed in a general "D" shape. When the first follower gear 230 and the second follower gear 330 rotate to the notch 12, the multiple meshing teeth 11 on the first follower gear 230 and the multiple meshing teeth 11 on the second follower gear 330 rotate past the rack 401. The first follower gear 230 and the rack 401, and the second follower gear 330 and the rack 401, disengage. Thus, the push plate 400 can freely pass through the gap defined between the notch 12 of the first follower gear 230 and the notch 12 of the second follower gear 330, achieving instantaneous jump. The two limiting structures 402 respectively cooperate with the first drive shaft 210 and the second drive shaft 310 to stop the push plate 400 in the falling position.

[0050] Therefore, the gear and rack combination enables the motor to continuously output stable torque, making the dust removal process stable and reliable; the gear and rack structure increases the stroke of the push plate 400, thereby increasing the opening and closing angle of the cup lid 20 and improving the dust removal capability; the dust removal mechanism 10 is subjected to stable load during movement, has a tight structural fit, and low noise; the design of the transmission gear and follower gear reduces the axial width of the original cam structure and reduces the space occupied by the mechanism.

[0051] According to a second aspect embodiment of the present invention, a dust collection station includes: a dust removal mechanism 10 and a dust cup as described in the first aspect embodiment of the present invention. The dust cup has a dust collection port and a cup cover 20. The cup cover 20 is connected to a push plate 400. When the push plate 400 is in the rising position, the cup cover 20 closes the dust collection port, and when the push plate 400 is in the falling position, the cup cover 20 is allowed to open the dust collection port.

[0052] When the main unit of the dust collection station detects the dust cup being placed inside, it drives the dust cup to open, and the cup cover 20 opens around the pivot. At the same time, the dust removal mechanism 10, driven by the geared motor, drives the gear to rotate, causing the push plate 400 to move up and down, realizing the reciprocating motion of the cup cover 20. During operation, the upward movement of the push plate 400 is achieved through the meshing of the gear and rack. After reaching the disengagement point, the push plate 400 is instantly dropped by the action of the dust cup, realizing the ejection of dust. After reaching the engagement point, the push plate 400 resumes its upward pushing function.

[0053] According to the dust collection station of the present invention, the dust removal mechanism 10 described above has a large driving force, good structural stability, low noise, high dust removal capacity, compact structure, and small space occupation.
