Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
In order to solve the technical problems that a dust collector in the prior art is inconvenient for users to clean the filter elements and the cleaning efficiency of the filter elements is low, an embodiment of the invention provides a dust collector. The dust collector includes a dirt cup and a separation assembly movable relative to the dirt cup, the separation assembly including a filter element. The dust collector also includes a wiping assembly that abuts the filter element. The dust collector further comprises a transmission mechanism, the dust cup, the separating component and the wiping component are in transmission connection through the transmission mechanism, and the transmission mechanism is used for driving the wiping component to synchronously move relative to the dust cup when the separating component moves relative to the dust cup, and the moving stroke of the wiping component relative to the filtering component is larger than that of the separating component relative to the dust cup. As described in detail below.
Referring to fig. 1 and 2, fig. 1 is an exploded view of an embodiment of a dust collector of the present invention, and fig. 2 is a view illustrating an assembled state of the dust collector shown in fig. 1.
In one embodiment, the dust collector 10 can be applied to a cleaning device such as a handheld vacuum cleaner, a vertical vacuum cleaner, a sweeping robot, etc., and plays a role in collecting dust, sundries, etc., and is convenient for a user to clean by dumping at one time.
Specifically, the dust collector 10 includes a dirt cup 11 and a separating assembly 12, the separating assembly 12 being movable relative to the dirt cup 11. The cleaning device using the dust collector 10 of this embodiment further includes a fan assembly 13, and the fan assembly 13 works to enable the cleaning device to perform cleaning work, generate dust-carrying airflow (carrying the garbage collected by the cleaning device) in the dust collector 10, and further perform garbage separation.
The separation module 12 includes a filter element 121, as shown in fig. 1-3. The filtering member 121 serves as a filtering element between the dust cup 11 and the separating assembly 12, wherein the dust cup 11 serves as a primary garbage separating medium, the dust-laden airflow (carrying the garbage collected by the cleaning device) in the dust cup 11 passes through the filtering member 121 and then enters the separating assembly 12 to be subjected to secondary separation by the separating assembly 12, and the filtering member 121 is used for filtering large-particle garbage and only small-particle garbage enters the separating assembly 12 to be subjected to secondary separation.
The filter elements 121 may be arranged circumferentially around the separation module 12. Also, the filtering member 121 is preferably a porous structure with a small pore size, and is used for filtering large-particle garbage, and only small-particle garbage smaller than the pore size enters the separation module 12.
Preferably, the separation assembly 12 may be a cyclone separator or the like, which is a device for separating a gas-solid system or a liquid-solid system, and the specific working principle is that solid particles or liquid drops with larger inertial centrifugal force are thrown to the outer wall surface to be separated by virtue of the rotating motion caused by the tangential introduction of the gas flow. The separation assembly 12 of the present embodiment is mainly applied to the separation of a gas-solid system, i.e. the separation of solid particle garbage. Also, the separating assembly 12 of the present embodiment may be specifically a multi-cone cyclone type, a single-cone cyclone type, or the like.
Of course, in other embodiments of the present invention, the separating component 12 may also be a porous Filter screen or the like, such as a Filter screen meeting the HEPA (High efficiency particulate air Filter) standard; or the separating element 12 may be a simple separating type design, which is not limited herein.
FIG. 3 illustrates the case where the separating assembly 12 is a cyclonic separator of the multi-cyclone type, which is required for purposes of discussion only and is not intended to be limiting.
Please continue to refer to fig. 1 and 2. Due to the porous design of the filter member 121, hair is easy to be entangled, especially in the specific application environment of pet cleaning, and the filter member 121 is often entangled with too much garbage such as hair, so that the filter member 121 needs to be additionally cleaned each time the dust cup 11 falls down, which is very inconvenient for users to use. Further, it is difficult to achieve a good cleaning effect of the garbage such as hair wound around the filter member 121 by a general cleaning means.
In view of this, the dust collector 10 of the present embodiment further includes a wiping member 14 and a transmission mechanism 15. The wiping component 14 abuts the filter element 121. The dust cup 11, the separating assembly 12 and the wiping assembly 14 are in transmission connection through a transmission mechanism 15, and the transmission mechanism 15 is used for driving the wiping assembly 14 to move synchronously relative to the dust cup 11 when the separating assembly 12 moves relative to the dust cup 11, so that the wiping assembly 14 moves relative to the filter element 121 on the separating assembly 12, and the filter element 121 is wiped and cleaned.
Specifically, when the user needs to pour dust from the dust cup 11, the user drives the separating assembly 12 to move relative to the dust cup 11 (specifically, the separating assembly 12 may be fixed, and the user pulls the dust cup 11 to move the separating assembly 12 relative to the dust cup 11), so that the wiping assembly 14 is driven by the transmission mechanism 15 to move synchronously relative to the dust cup 11, so that the wiping assembly 14 moves relative to the filter 121 on the separating assembly 12 to wipe and clean the filter 121. Therefore, during the dust dumping process, the user can clean the filter element 121 by wiping the wiping component 14 along the belt, without additionally cleaning the filter element 121, which is convenient for the user to use and can improve the convenience for the user to clean the filter element 121.
Moreover, the travel of the wiping component 14 moving relative to the filtering component 121 is greater than the travel of the separating component 12 moving relative to the dust cup 11, which means that the user makes the separating component 12 move relatively to the dust cup 11 by a small travel, i.e. the wiping component 14 moves relatively to the filtering component 121 by a large travel, so that the use burden of the user can be effectively reduced, the convenience of the user for cleaning the filtering component 121 is further improved, meanwhile, the cleaning efficiency of the filtering component 121 is also significantly improved, and the user can be ensured to clean the filtering component 121 quickly and effectively.
In one embodiment, during the process of moving the separating element 12 relative to the dust cup 11, the separating element 12 and the wiping element 14 respectively move in opposite directions relative to the dust cup 11, so that the distance traveled by the wiping element 14 relative to the filter element 121 is greater than the distance traveled by the separating element 12 relative to the dust cup 11, thereby improving the convenience of the user in cleaning the filter element 121 and improving the cleaning efficiency of the filter element 121.
The following description is directed to a design that achieves movement of the separator assembly 12 and the wiper assembly 14, respectively, in opposition to each other relative to the dirt cup 11 during movement of the separator assembly 12 relative to the dirt cup 11.
Please continue to refer to fig. 1 and 2. In one embodiment, the transmission mechanism 15 includes a gear assembly 151, a first rack 152, and a second rack 153. The gear assembly 151 is disposed on the dust cup 11, the first rack 152 is disposed on the separating assembly 12, the second rack 153 is disposed on the wiping assembly 14, and the gear assembly 151 is respectively engaged with the first rack 152 and the second rack 153, so as to drive the wiping assembly 14 to synchronously move relative to the dust cup 11 when the separating assembly 12 moves relative to the dust cup 11.
Further, the gear assembly 151 is disposed on the inner wall of the dust cup 11, a gap 154 is formed between the gear assembly 151 and the inner wall of the dust cup 11 where the gear assembly is located, and the second rack 153 penetrates through the gap 154 and is engaged with the gear assembly 151.
Further, the present embodiment is designed with a plurality of sets of gear assemblies 151, a first rack 152 and a second rack 153, wherein the gear assemblies 151, the first rack 152 and the second rack 153 are engaged with each other in a one-to-one correspondence. Specifically, a plurality of sets of gear assemblies 151 are disposed on the dust cup 11 and spaced from each other along the circumferential direction of the dust cup 11, a plurality of first racks 152 are disposed on the separating assembly 12 and spaced from each other along the circumferential direction of the separating assembly 12, a plurality of second racks 153 are disposed on the wiping assembly 14 and spaced from each other along the circumferential direction of the wiping assembly 14, and the gear assemblies 151, the first racks 152 and the second racks 153 are engaged with each other in a one-to-one correspondence manner, so as to facilitate the matching transmission among the dust cup 11, the separating assembly 12 and the wiping assembly 14, as shown in fig. 1 and 4.
Please continue with fig. 2. In one embodiment, the gear assembly 151 includes a single level gear 1511. Opposite sides of the single-layer gear 1511 are engaged with the first rack 152 and the second rack 153, respectively. In this manner, the separating assembly 12 and the wiping assembly 14 move in opposite directions relative to the dirt cup 11 during movement of the separating assembly 12 relative to the dirt cup 11, wherein the wiping assembly 14 must move a greater distance relative to the filter element 121 than the separating assembly 12 does relative to the dirt cup 11.
It should be noted that the stroke of the wiping component 14 moving relative to the filter element 121 in this embodiment is two times the stroke of the separating component 12 moving relative to the dirt cup 11, which means that the wiping component 14 will move relative to the filter element 121 by two times the stroke of the separating component 12 moving relative to the dirt cup 11, so as to improve the convenience of the user in cleaning the filter element 121 and improve the cleaning efficiency of the filter element 121.
As shown in fig. 5, fig. 5 shows the dust dumping process of the dust collector of the present embodiment. Specifically, the separating assembly 12 is relatively stationary and the user pulls on the dirt cup 11 such that the dirt cup 11 moves a distance H relative to the separating assembly 12. In the process, the wiping member 14 moves a distance of 2H relative to the separating member 12 in the moving direction of the dirt cup 11. Wherein the direction of movement of the dirt cup 11 and wiper assembly 14 is shown by arrow X in figure 5. Of course, in other embodiments of the present invention, the dirt cup 11 may be fixed relatively, and the user may pour the dirt by pulling the separating assembly 12, which is not limited herein.
Please continue to refer to fig. 2 and 4. Specifically, two installation blocks 111 spaced from each other are disposed on the inner wall of the dust cup 11 at the position of the single-layer gear 1511, the single-layer gear 1511 is disposed on a rotating shaft 112 in a penetrating manner, and two ends of the rotating shaft 112 are disposed in the two installation blocks 111 spaced from each other in a penetrating manner respectively. A gap 154 is arranged between the single-layer gear 1511 and the inner wall of the dust cup 11 at the position of the single-layer gear 1511, and the second rack 153 is arranged in the gap 154 in a penetrating way and is meshed with the single-layer gear 1511.
Referring to fig. 2 and 6, fig. 6 is a schematic structural view of a gear assembly according to a first embodiment of the present invention. Fig. 2 shows the gear assembly 151 as a single-level gear 1511. It is understood that the present embodiment has the first gear 1512 and the second gear 1513 coaxially disposed to directly replace the single-layer gear 1511 shown in the figures.
In an alternative embodiment, the gear assembly 151 includes a first gear 1512 and a second gear 1513 that are coaxially disposed. Specifically, the first gear 1512 and the second gear 1513 are fixed relative to each other, so that the first gear 1512 and the second gear 1513 rotate synchronously, and therefore the rotation angles of the first gear 1512 and the second gear 1513 are the same. The first gear 1512 is engaged with the first rack 152, and the second gear 1513 is engaged with the second rack 153.
In this manner, the separating assembly 12 and the wiping assembly 14 move in opposite directions relative to the dirt cup 11 during movement of the separating assembly 12 relative to the dirt cup 11, wherein the wiping assembly 14 must move a greater distance relative to the filter element 121 than the separating assembly 12 does relative to the dirt cup 11.
It should be noted that the difference between the travel of the wiping unit 14 relative to the filter element 121 and the travel of the separating unit 12 relative to the dirt cup 11 can be adjusted by adjusting the size (diameter or radius) of the first gear 1512 and the second gear 1513.
For example, when the second gear 1513 is smaller than the first gear 1512, the wiping element 14 moves relative to the filter element 121 by a distance greater than the distance that the separating element 12 moves relative to the dirt cup 11, but the wiping element 14 moves relative to the filter element 121 by a distance less than twice the distance that the separating element 12 moves relative to the dirt cup 11; when the second gear 1513 is equal to the first gear 1512, the wiping component 14 moves twice as far relative to the filter element 121 as the separating component 12 moves relative to the dirt cup 11; and when the second gear 1513 is larger than the first gear 1512, the wiping component 14 will travel more than twice as much relative to the filter elements 121 as the separating component 12 will travel relative to the dirt cup 11.
Referring to fig. 2 and 7, fig. 7 is a schematic structural view of a gear assembly according to a second embodiment of the present invention. Fig. 2 shows the gear assembly 151 as a single-level gear 1511. It will be appreciated that the present embodiment directly replaces the single-layer gear 1511 shown in the figures with a plurality of cascaded gear-cascade geared first gear 1512 and second gear 1513.
In another alternative embodiment, the gear assembly 151 includes a first gear 1512 and a second gear 1513, and the first gear 1512 and the second gear 1513 are in cascade mesh transmission via a plurality of cascaded gears, so that the first gear 1512 and the second gear 1513 rotate at the same angle. Here, the first gear 1512 meshes with the first rack 152, the second gear 1513 meshes with the second rack 153, and the rotation directions of the first gear 1512 and the second gear 1513 are the same.
In this manner, the separating assembly 12 and the wiping assembly 14 move in opposite directions relative to the dirt cup 11 during movement of the separating assembly 12 relative to the dirt cup 11, wherein the wiping assembly 14 must move a greater distance relative to the filter element 121 than the separating assembly 12 does relative to the dirt cup 11.
It should be noted that the difference between the moving distance of the wiping unit 14 relative to the filter 121 and the moving distance of the separating unit 12 relative to the dirt cup 11 can be adjusted by adjusting the sizes (diameters or radii) of the first gear 1512 and the second gear 1513 as described in the above embodiments, and will not be described herein again.
For example, the first gear 1512 and the second gear 1513 may be in cascade mesh transmission via an odd number of cascade gears, so that the rotation directions of the first gear 1512 and the second gear 1513 are the same, which is not limited herein.
In one embodiment, the separating assembly 12 and the wiping assembly 14 move in the same direction relative to the dirt cup 11 during movement of the separating assembly 12 relative to the dirt cup 11, and the wiping assembly 14 moves relative to the dirt cup 11 by a distance greater than twice the distance that the separating assembly 12 moves relative to the dirt cup 11, such that the distance that the wiping assembly 14 moves relative to the filter element 121 is greater than the distance that the separating assembly 12 moves relative to the dirt cup 11.
The following description is directed to a design for effecting movement of the separator assembly 12 and the wiper assembly 14, respectively, in a same direction relative to the dirt cup 11 during movement of the separator assembly 12 relative to the dirt cup 11.
Referring to fig. 2 and 8, fig. 8 is a schematic structural view of a gear assembly according to a third embodiment of the present invention. Fig. 2 shows the gear assembly 151 as a single-level gear 1511. It will be appreciated that the present embodiment directly replaces the single-layer gear 1511 shown in the figures with a plurality of cascaded gear-cascade geared first gear 1512 and second gear 1513.
In one embodiment, the gear assembly 151 includes a first gear 1512 and a second gear 1513, and the first gear 1512 and the second gear 1513 are in cascade mesh transmission via a plurality of cascaded gears, so that the rotation angles of the first gear 1512 and the second gear 1513 are the same. Wherein the first gear 1512 is engaged with the first rack 152, the second gear 1513 is engaged with the second rack 153, and the rotation directions of the first gear 1512 and the second gear 1513 are opposite.
In this manner, the separating assembly 12 and the wiping assembly 14 move in the same direction relative to the dirt cup 11 during movement of the separating assembly 12 relative to the dirt cup 11. This requires that the wiping assembly 14 travel more than twice the distance that the separating assembly 12 travels relative to the dirt cup 11, and thus that the wiping assembly 14 travel more than the distance that the separating assembly 12 travels relative to the dirt cup 11 relative to the filter element 121.
Preferably, the difference between the travel of the wiper assembly 14 relative to the dirt cup 11 and the travel of the separator assembly 12 relative to the dirt cup 11 can be adjusted by adjusting the size (diameter or radius) of the first gear 1512 and the second gear 1513. Specifically, it is possible to adjust the second gear 1513 to be greater than twice the size of the first gear 1512, as shown in FIG. 8, so that the wiping assembly 14 moves relative to the dirt cup 11 by more than twice the travel of the separating assembly 12 relative to the dirt cup 11, and so that the wiping assembly 14 moves relative to the filter element 121 by more than the travel of the separating assembly 12 relative to the dirt cup 11.
For example, the first gear 1512 and the second gear 1513 may be in cascade mesh transmission via an even number of cascade gears, so that the rotation directions of the first gear 1512 and the second gear 1513 are opposite, and the present invention is not limited herein.
Referring to fig. 2 and 9, fig. 9 is a schematic sectional view of a wiping assembly of the dust collector shown in fig. 1. The design of the wiping component 14 is explained below.
In one embodiment, the wiper assembly 14 includes a frame 141 and a wiper 142. A second rack 153 and a wiper 142 are respectively provided on the frame 141, the wiper 142 also abutting against the outer surface of the filter element 121, so as to clean the filter element 121 by means of the wiper 142 during the movement of the wiper element 14 with respect to the separating element 12.
Specifically, the frame 141 is sleeved on the outer periphery of the separating assembly 12, and has a tapered shape with a first opening 1411 and a second opening 1412 that are oppositely disposed and communicated. The opening area of the first opening 1411 is smaller than that of the second opening 1412. In this way, the frame 141 forms a barrier in the space between the separating assembly 12 and the inner wall of the dirt cup 11, and guides the garbage cleaned up on the filter member 121 to the bottom of the dirt cup 11 as much as possible.
And, the second rack 153 is provided at the second opening 1412, further extending away from the frame 141 to engage with the gear assembly 151. The wiping member 142 is disposed around the edge of the first opening 1411, and then is sleeved on the outer periphery of the filter member 121 and abuts against the outer surface of the filter member 121, so as to wipe and clean the filter member 121 in the process that the wiping member 142 moves relative to the filter member 121.
Further, the wiper 142 is preferably a wiping soft gel or the like. Also, the wiper 142 is preferably an interference fit with the filter element 121, such that the wiper 142 abuts the surface of the filter element 121 to ensure the cleaning effect of the wiper 142.
Further, a sealing groove 143 circumferentially surrounding the frame 141 is provided on the outer surface of the frame 141 near the second opening 1412, and a sealing ring 144 is provided in the sealing groove 143, and the sealing ring 144 abuts against the inner wall of the dirt cup 11, as shown in fig. 2 and 9. In this way, the sealing ring 144 not only can seal, but also the sealing ring 144 can cling to the inner wall of the dust cup 11 and can clean the inner wall of the dust cup 11 during the movement of the wiping component 14 relative to the dust cup 11.
In summary, the transmission mechanism of the dust collector provided by the present invention is used for driving the wiping component to move synchronously relative to the dust cup when the separating component moves relative to the dust cup, so that the wiping component moves relative to the filtering component on the separating component, and further, the filtering component is wiped and cleaned. Wherein, the stroke that the subassembly removed is filtered relatively to the wiping subassembly is greater than the stroke that the relative dirt cup of separator assembly removed, means that the user makes the relative dirt cup of separator assembly remove less stroke, can make the subassembly of wiping remove great stroke relatively to filtering, can effectively alleviate user's use burden, improves the convenience that the user cleaned the filter, and the clean efficiency of filtering simultaneously has also obtained showing and has improved.
