[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] After long-term research, the inventors found that cleaning devices such as vacuum cleaners or sweeping robots rely on negative pressure to absorb debris, garbage, dust, etc., and use the filter screen of the dust box to filter the airflow formed in the cleaning device, leaving debris, garbage, dust and other objects in the accommodating cavity. After long-term use of the cleaning device, a large amount of dust and debris will be attached to the filter screen, affecting the filtering performance of the filter screen and hindering the flow of airflow. Generally, the filter screen needs to be removed from the cleaning device and then cleaned, which makes the cleaning of the filter screen too cumbersome. Moreover, repeatedly removing and installing the filter screen on the cleaning device will also affect the performance of the cleaning device, such as the sealing of the cleaning device, resulting in a decrease in the service life of the cleaning device. In order to improve the above technical problems, the inventors of this application have proposed the following embodiments after long-term research and development and testing.

[0032] See also Figure 1 and Figure 2 The dust box self-cleaning system 1 described in the embodiment of the dust box self-cleaning system of the present application may include: a dust box assembly and multiple fans 21. The dust box assembly at least includes a dust box 10 and multiple filters 15. In this embodiment, the multiple fans 21 refer to at least two fans 21, that is, two or more fans 21.

[0033] See also Figure 2 , Figure 3 and Figure 4 The dust box 10 can be used to accommodate the objects to be processed that are sucked, wherein the objects to be processed can be garbage objects such as debris, paper scraps, dust, and hair. The dust box 10 can have a accommodating chamber 100, multiple air outlets 120, a channel chamber 130, and multiple connecting ports 140. The accommodating chamber 100 can accommodate garbage objects such as debris, paper scraps, dust, and hair that are sucked. The dust box 10 can also have a dust suction port 110 connected to the accommodating chamber 100. The dust suction port 110 is used to guide the external objects to be processed into the accommodating chamber 100. In this embodiment, the multiple air outlets 120 refer to at least two air outlets 120, that is, two or more air outlets 120.

[0034] like Figure 3 As shown, the channel cavity 130 can be spaced apart from the accommodating cavity 100. The channel cavity 130 can have a plurality of channel sub-cavities 1310 that are independent of each other. A plurality of communication ports 140 can be spaced apart, and each communication port 140 can be connected to a corresponding channel sub-cavity 1310 and the accommodating cavity 100. Figure 3 and Figure 4As shown, the channel sub-cavity 1310 and the connecting port 140 can correspond one to one, that is, each channel sub-cavity 1310 can be connected to a connecting port 140, and the connecting ports 140 connected to different channel sub-cavities 1310 are different. Each air outlet 120 corresponds to a channel sub-cavity 1310. Different air outlets 120 can correspond to different channel sub-cavities 1310. In this way, under the action of the fan 21, the dust suction port 110, the accommodating chamber 100, the connecting port 140, the channel sub-cavity 1310 and the air outlet 120 become channels through which the airflow flows. Compared with the accommodating chamber 100, the multiple channel sub-cavities 1310 are located downstream of the airflow, that is, under the suction action of the fan 21, the airflow enters the accommodating chamber 100 from the dust suction port 110, and then is diverted from the accommodating chamber 100 to each channel sub-cavity 1310, and finally flows out through the air outlet 120 corresponding to the channel sub-cavity 1310. In this embodiment, the multiple channel sub-cavities 1310 refer to at least two channel sub-cavities 1310, that is, two or more channel sub-cavities 1310, and the multiple connecting ports 140 refer to at least two channel sub-cavities 1310, that is, two or more channel sub-cavities 1310.

[0035] A plurality of fans 21 are provided corresponding to a plurality of air outlets 120, each fan 21 corresponds to an air outlet 120, and at least one fan 21 is provided for each air outlet 120. Different fans 21 may correspond to different air outlets 120. For example, at least two fans 21 correspond to at least two air outlets 120, respectively. The fans 21 and the air outlets 120 may correspond one to one. The fan 21 is mainly used to extract air through the air outlet 120, and form an airflow through the dust suction port 110, the accommodating chamber 100, the connecting port 140, the channel sub-chamber 1310 and the air outlet 120, so as to absorb the objects to be processed into the accommodating chamber 100. The objects to be processed may be the above-mentioned debris, paper scraps, dust, hair and other garbage objects. The positions, specific structures, etc. of the fans 21 and the air outlets 120 are not limited to the contents mentioned in this embodiment and Figure 1 and Figure 2 Examples presented by etc.

[0036] By providing multiple fans 21 and multiple air outlets 120, and multiple fans 21 are provided corresponding to multiple air outlets 120, multiple airflow channels can be formed. When multiple fans 21 are working, multiple airflows can work together to remove the air in the accommodating chamber 100 more quickly, so that the suction port 110 can generate greater suction to suck in garbage objects. Compared with the design of a single fan 21 and a single air duct, this embodiment can absorb garbage objects with larger volume and heavier mass, and can effectively improve the cleaning effect.

[0037] A plurality of filter elements 15 may be provided corresponding to a plurality of communication ports 140, and at least one filter element 15 is provided for each communication port 140. The filter element 15 is used to filter the airflow passing through the communication port 140, and to leave garbage objects in the accommodating chamber 100. The filter element 15 is, for example, a filter net, a filter box, an activated carbon adsorption net, an activated carbon adsorption box, etc. In this embodiment, the plurality of filter elements 15 refers to at least two filter elements 15, that is, two or more filter elements 15.

[0038] When some of the fans 21 are working and the rest of the fans 21 are not working, the air outlets 120, the channel sub-cavities 1310 and the connecting openings 140 corresponding to the rest of the fans 21 that are not working further form a channel through which air flows with the accommodating chamber 100 and the connecting openings 140, the channel sub-cavities 1310 and the air outlets 120 corresponding to some of the fans 21. Some of the fans 21 extract air through the corresponding air outlets 120, which can form a forward airflow that flows through the corresponding connecting openings 140, the channel sub-cavities 1310 and the air outlets 120 in sequence, and can also form a reverse airflow in the air outlets 120, the channel sub-cavities 1310, the connecting openings 140 and the accommodating chamber 100 corresponding to the rest of the fans 21 that are not working.

[0039] When the fan 21 draws air to make the accommodating chamber 100 absorb garbage objects, dust and other garbage objects are easy to adhere to the side of the filter 15 adjacent to the accommodating chamber 100. In this embodiment, the reverse airflow is formed to drive the garbage objects attached to the filter 15 corresponding to the other fans 21 that are not working, so that the garbage objects fall off from the filter 15 corresponding to the other fans 21 that are not working and are accommodated in the accommodating chamber 100, and the filter 15 corresponding to the other fans 21 that are not working is self-cleaned. In this way, the filter 15 can be automatically self-cleaned by the cleaning device through repeated use of the forward airflow and the reverse airflow without disassembling the filter 15, reducing the cleaning process and process, improving the efficiency of cleaning the filter 15, reducing the number of times the cleaning device is disassembled, and thus improving the service life of the cleaning device.

[0040] After the filters 15 corresponding to the remaining fans 21 that are not working are cleaned, the working states of some fans 21 and the remaining fans 21 are switched (that is, the remaining fans 21 are working, and some fans 21 are not working), so that the filters 15 corresponding to some fans 21 can be cleaned. In this way, it is possible to clean the filters 15 corresponding to the remaining fans 21 and the filters 15 corresponding to some fans 21, thereby achieving the effect of self-cleaning all the filters 15 in the dust box self-cleaning system 1.

[0041] like Figure 2As shown, the passage cavity 130 and the accommodating cavity 100 may be disposed adjacent to each other in the thickness direction of the dust box 10. The dimension of the passage cavity 130 in the thickness direction of the dust box 10 may be smaller than the dimension of the accommodating cavity 100 in the thickness direction of the dust box 10.

[0042] Since the dimension of the channel cavity 130 in the thickness direction of the dust box 10 is smaller than the dimension of the accommodating cavity 100 in the thickness direction of the dust box 10 , the cross-sectional area through which the airflow flows in the channel cavity 130 is smaller than the cross-sectional area through which the airflow flows in the accommodating cavity 100 . The cross-sectional area through which the airflow in the channel cavity 130 flows is the sum of the cross-sectional areas through which the airflow in each channel sub-cavity 1310 flows. Further, under the suction action of the fan 21, the velocity of the airflow flowing through each channel sub-cavity 1310 is faster than the velocity of the airflow flowing through the accommodating cavity 100. In this way, a low pressure relative to the accommodating cavity 100 can be effectively and quickly formed in the channel sub-cavity 1310, so as to increase the force of the connecting port 140 on sucking the air in the accommodating cavity 100, and press the garbage objects entering the accommodating cavity 100 through the dust suction port 110 into the area of ​​the accommodating cavity 100 near the connecting port 140, thereby preventing the garbage objects entering the accommodating cavity 100 through the dust suction port 110 from accumulating near the dust suction port 110, thereby affecting the garbage objects passing through the dust suction port 110, thereby affecting the suction of the garbage objects by the dust suction port 110.

[0043] like Figures 1 to 3 As shown, in order to better cooperate with the fan 21 and the air outlet 120, facilitate the connection between the two and adapt to the structure of the dust box 10, etc., the dust box self-cleaning system 1 may also include a connector 22. The fan 21 can be connected to the connector 22, and can be connected to the air outlet 120 through the connector 22. The fan 21 is connected to the air outlet 120 through the connector 22, that is, the air in the accommodating chamber 100 can be extracted from the air outlet 120 through the connector 22. A connector 22 and a fan 21 can be used as a group of dust collection components 20. The dust box self-cleaning system 1 of this embodiment can be provided with multiple air outlets 120, and multiple groups of dust collection components 20 are correspondingly provided. By providing a connector 22 to cooperate with the fan 21 to connect the air outlet 120, it is possible to facilitate the installation of the fan 21 and the structural arrangement and design of the entire component, and the connection 22 can extend the air duct, which can speed up the air flow speed and further enhance the suction force and cleaning effect of the dust suction port 110.

[0044] By setting the dust box 10 to form a plurality of communication ports 140 arranged at intervals, each communication port 140 corresponds to a channel sub-cavity 1310 and the accommodating chamber 100, and the airflow flowing from the accommodating chamber 100 to the channel cavity 130 is diverted to each channel sub-cavity 1310, so that the airflow flowing from the accommodating chamber 100 to the channel cavity 130 is divided into multiple paths, so that each communication port 140 has airflow inflow, and the coordinated work of multiple airflows can effectively enhance the suction force in the accommodating chamber 100, and effectively absorb the objects to be processed. Moreover, the objects to be processed enter the accommodating chamber 100 through the dust suction port 110, and can be distributed to the vicinity of each communication port 140 under the drive of the airflow, so as to avoid accumulation near only one communication port 140, reduce the probability of blockage of the communication port, and improve the space utilization rate of the accommodating chamber 100.

[0045] like Figure 2 and Figure 3 As shown, the plurality of air outlets 120 may be spaced apart from the dust suction port 110 and surround the thickness direction of the dust box 10, and may be arranged on the peripheral side of the dust box 10. For example, the plurality of air outlets 120 may be formed on two opposite sides of the dust box 10, and the two opposite sides of the dust box 10 surround the thickness direction of the dust box 10. The dust suction port 110 may be located on different sides from the air outlet 120, and the side where the dust suction port 110 is located and the two opposite sides where the plurality of air outlets 120 are located are also arranged around the thickness direction of the dust box 10.

[0046] Specifically, when the number of the air outlets 120 is two, the two air outlets 120 can be formed on two opposite sides of the dust box 10. For example, the arrangement direction of the two air outlets 120 is perpendicular to the thickness direction of the dust box 10, which can be roughly consistent with the length direction of the dust suction port 110. The dust suction port 110 is arranged at intervals from the two air outlets 120, and the dust suction port 110 is located between the two air outlets 120 and is not located on the same side as the two air outlets 120. The dust suction port 110 and the two air outlets 120 are respectively formed on the sides of the dust box 10 around its thickness direction, that is, the line connecting the dust suction port 110 and the two air outlets 120 in sequence is around the thickness direction of the dust box 10.

[0047] By arranging two air outlets 120 on opposite sides of the dust box 10 and locating the dust suction port 110 between the two air outlets 120, the air duct formed inside the dust box 10 can be made more balanced, ensuring effective synergy between the two fans 21 and reducing the noise generated by the airflow.

[0048] See also Figure 4 This embodiment can further describe an exemplary structure of the dust box 10, which is specifically described as follows:

[0049] The dust box 10 may include a first shell 11, a second shell 12, and a cover 13. One side of the second shell 12 may be covered on the first shell 11 to form a receiving chamber 100. A groove 1211 may be formed on the other side of the second shell 12. The cover 13 may be covered on the other side of the second shell 12 to cover the groove 1211 to form a channel chamber 130. A plurality of communication ports 140 may be spaced apart and opened in the second shell 12. The second shell 12 may be provided with a plurality of communication ports 140. Figure 2 , Figure 3 and Figure 4 The spacer 123 shown in the figure is used to separate the multiple communication ports 140 from each other, so that when the cover 13 covers the other side of the second shell 12, the spacer 123 separates the channel cavity 130 into multiple channel sub-cavities 1310 independent of each other. For example, the spacer 123 is protrudingly arranged on the other side of the second shell 12 or the side of the cover 13 facing the second shell 12, and corresponds to the multiple communication ports 140. When the cover 13 covers the other side of the second shell 12, the spacer 123 can be connected between the cover 13 and the second shell 12 to separate the channel cavity 130 into multiple channel sub-cavities 1310 independent of each other. Each communication port 140 passes through one side of the second shell 12 to the other side of the second shell 12, so as to connect a channel sub-cavity 1310 and the accommodating cavity 100. The thickness direction of the dust box 10 can be the direction from the first shell 11 to the cover 13 and the opposite direction. The accommodation chamber 100 and the passage chamber 130 may be separated by the second housing 12 so as to be spaced apart.

[0050] like Figure 5 As shown, in order to make the partition plate 123 better partition the channel cavity 130 into a plurality of channel sub-cavities 1310 and make the structure more stable, correspondingly, the cover body 13 may be provided with a corresponding engaging groove 1000 on the side facing the second shell 12 or the other side of the second shell 12, that is, if the partition plate 123 is protrudingly disposed on the other side of the second shell 12, the engaging groove 1000 is provided on the side facing the second shell 12 of the cover body 13, and if the partition plate 123 is protrudingly disposed on the side facing the second shell 12 of the cover body 13, the engaging groove 1000 is provided on the other side of the second shell 12. The partition plate 123 can be embedded in the engaging groove 1000, so that when the cover body 13 covers the other side of the second shell 12, the partition plate 123 is embedded in the engaging groove 1000, thereby partitioning the channel cavity 130 into a plurality of channel sub-cavities 1310 that are independent of each other.

[0051] like Figure 4As shown, the first shell 11 can be, for example, arranged in a groove shape, for example, it can include a bottom wall 111 and a side wall 112 arranged around the bottom wall 111, and the bottom wall 111 and the side wall 112 constitute a groove structure. When the second shell 12 is covered on the first shell 11, the groove structure is covered to form a accommodating cavity 100. The dust suction port 110 can be opened on the side wall 112 of the first shell 11. The dust box 10 can also include a dust suction part 14, which is connected to the dust suction port 110 of the first shell 11, and the side of the dust suction part 14 facing away from the dust suction port 110 is inclined. For example, the angle between the plane where the side of the dust suction part 14 facing away from the dust suction port 110 is located and the plane where the dust suction port 110 is located is greater than 0° and less than 90°, for example, 45°. Of course, the dust suction port 110 may also be opened in the second shell 12 , or a portion of the dust suction port 110 may be opened in each of the first shell 11 and the second shell 12 , so as to jointly form the dust suction port 110 when they are covered with each other.

[0052] like Figure 4 As shown, the second shell 12 includes, for example, a top wall 121 and an extension 122. The extension 122 is connected to the edge area of ​​the top wall 121, and can, for example, extend in the direction of the top wall 121 toward the side of the first shell 11. Optionally, the second shell 12 can include two extensions 122, which are arranged opposite to each other. When the second shell 12 is covered on the first shell 11 for assembly, the top wall 121 is covered on the side wall 112 of the first shell 11, the extension 122 is arranged opposite to the side wall 112 of the first shell 11, and a part of the side wall 112 of the first shell 11 is sandwiched between the two extensions 122.

[0053] Specifically, one side of the top wall 121 can be covered on the side wall 112 of the first shell 11, so that the second shell 12 and the first shell 11 cooperate to form the accommodating cavity 100. Figure 4 As shown, a groove 1211 is formed on the other side of the top wall 121. Each extension 122 has a space connected to the groove 1211, and the side of the extension 122 away from the top wall 121 can form an air outlet 120, and the air outlet 120 is connected to the space. The cover 13 is covered on the other side of the top wall 121, so that the cover 13 and the second shell 12 cooperate to form a channel cavity 130, and the air outlet 120 is connected to the channel cavity 130. A plurality of communication ports 140 are spaced apart from each other on the top wall 121. The partition plate 123 can be protruded from the other side of the top wall 121 and is disposed between the plurality of communication ports 140 to separate the plurality of communication ports 140 from each other.

[0054] like Figure 5As shown, the cover body 13 may be provided with a corresponding engaging groove 1000 that matches the partition plate 123 on one side facing the second shell 12, and the partition plate 123 may be embedded in the engaging groove 1000, so that when the cover body 13 is covered on the other side of the top wall 121, the partition plate 123 is embedded in the engaging groove 1000 and then abuts between the cover body 13 and the top wall 121, thereby partitioning the channel cavity 130 into a plurality of independent channel sub-cavities 1310. Of course, the top wall 121 may be provided with the engaging groove 1000, and the cover body 13 may be provided with the partition plate 123 accordingly, or both the top wall 121 and the cover body 13 may be provided with the engaging groove 1000, and the partition plate 123 may be embedded in the engaging groove 1000 of the top wall 121 and the engaging groove 1000 of the cover body 13.

[0055] like Figure 5 As shown, a buffer pad 1001 can be provided in the interlocking groove 1000. For example, the buffer pad 1001 can be laid in the interlocking groove 1000 and extend out of the interlocking groove 1000, so that when the partition plate 123 is inserted into the interlocking groove 1000, the buffer pad 1001 abuts between the partition plate 123 and the side wall of the interlocking groove 1000.

[0056] Each communication port 140 corresponds to a channel sub-cavity 1310 and a accommodating cavity 100. Each channel sub-cavity 1310 can correspond to a communication port 140 and an air outlet 120. Of course, the air outlet 120 can also be opened on the first shell 11, or opened on the first shell 11 and the second shell 12 at the same time. In other embodiments, the air outlet 120 can also be opened on the cover body 13. Optionally, the first shell 11 and the second shell 12 can be connected in a chimeric manner, for example, a chimeric groove (not marked) is provided on the periphery of one side of the top wall 121, and a chimeric edge (not marked) is provided on the periphery of the side wall 112 of the first shell 11. When the first shell 11 and the second shell 12 are covered, the chimeric edge is embedded in the chimeric groove for connection, so that the connection between the two can be made tighter and can also play a sealing role. Of course, a sealing member can be further provided in the chimeric groove to further enhance the sealing effect. In this embodiment, the second shell 12 and the cover body 13 may also be connected by a fitting manner, for example, by the cooperation of a fitting groove and a fitting edge.

[0057] like Figure 4As shown, the filter element 15 is used to filter the airflow passing through the filter element 15 so as to leave the object to be processed in the accommodating chamber 100. The filter element 15 may include a first filter screen 151 and a second filter screen 152. The filtering accuracy of the second filter screen 152 is less than that of the first filter screen 151. In other words, the second filter screen 152 can be used as a coarse filter screen (primary filter screen), and the first filter screen 151 can be used as a fine filter screen (high-efficiency filter screen). For example, for the first filter screen 151 and the second filter screen 152 both being mesh-shaped, the mesh size of the second filter screen 152 can be larger than the mesh size of the first filter screen 151. For example, the second filter screen 152 can have 4 meshes, and the first filter screen 151 can have 100 meshes. The overall size of the second filter screen 152 and the overall size of the first filter screen 151 are both comparable to the size of the connecting port 140, so that the mesh size of the second filter screen 152 is larger than the mesh size of the first filter screen 151. Of course, the first filter screen 151 can be as follows Figure 2 and Figure 3 The foldable filter shown in the figure, the filter element of the first filter 151 is, for example, Figure 2 and Figure 3 The continuous Z-fold shape shown.

[0058] The second filter screen 152 and the first filter screen 151 can be disposed in the second housing 12 and cover the communication port 140 in sequence. Specifically, the second housing 12 can be provided with a "cross" bracket (such as Figure 4 As shown, not marked), of course, it can also be other shapes, and the bracket can be used to carry the second filter 152 and the first filter 151, so that both are more stably placed on the second shell 12. Under the suction action of the fan 21, garbage, debris and other objects enter the accommodating chamber 100 from the dust suction port 110 with the airflow. Due to the dual filtering effect of the second filter 152 and the first filter 151, the airflow is filtered by the second filter 152 and the first filter 151 in turn, and the objects to be processed are left in the accommodating chamber 100, and the filtered air enters the channel sub-chamber 1310 and is extracted through the air outlet 120.

[0059] By providing a combined design of the first shell 11, the second shell 12 and the cover 13, the dust box 10 can have a better structural stability and be easy to disassemble and assemble, which is beneficial to the cleaning of garbage objects and the maintenance of the dust box 10. Moreover, the combined structure of the dust box 10 facilitates the first shell 11 and the second shell 12 to cooperate to form the accommodating chamber 100, and the second shell 12, the cover 13 and the partition plate 123 to cooperate to form at least two channel sub-cavities 1310, so that different fans 21 can work in time-sharing mode, so that the fans 21 can reversely clean the corresponding filter elements 15, so as to achieve automatic cleaning of the filter elements 15 of the dust box 10, thereby maintaining a better cleaning effect of the dust box 10, so that the accommodating chamber 100 can better accommodate objects such as sundries and garbage, and at the same time, the multiple channel sub-cavities 1310 can discharge the air in the accommodating chamber 100 more quickly, thereby accelerating the flow speed of the airflow.

[0060] Furthermore, a multi-stage filtering system is provided, and the second filter screen 152 and the first filter screen 151 can perform multiple filtering on the airflow, ensuring that debris, dust and other garbage objects can be effectively filtered and stored in the accommodating chamber 100, achieving a good cleaning effect. Of course, the number of the communication port 140 can also be multiple, and an example will be given later in this embodiment.

[0061] like Figure 4 As shown, the cover 13 is used to cover the second shell 12 and cooperate with the second shell 12 to form a channel cavity 130. In this embodiment, the cover 13 and the second shell 12 can be sealed by a first sealing member 16 whose shape is adapted to the appearance of the two. Figure 4 As shown, the cover body 13 may include a cover body main body 131 and a filter screen upper cover 132. A mounting hole 1311 is formed at a position of the cover body main body 131 corresponding to the first filter screen 151, and the mounting hole 1311 is connected to the channel cavity 130. When the cover body main body 131 is covered on the side wall 112 on the first shell 11, the first filter screen 151 and the second filter screen 152 can be exposed. Optionally, the filter screen upper cover 132 is rotatably connected to the cover body main body 131. For example, one side edge of the filter screen upper cover 132 is rotatably arranged on the inner wall of the mounting hole 1311 surrounded by the cover body main body 131 through a rotating shaft. The filter screen upper cover 132 can cover the mounting hole 1311 by rotating, or open the mounting hole 1311 to expose the first filter screen 151 and the second filter screen 152.

[0062] Furthermore, the filter cover 132 can cooperate with the mounting hole 1311 through a second sealing member 17 adapted to the shape of the mounting hole 1311 to improve the sealing effect of the dust box 10 and ensure the suction force of the dust suction port 110 and the effective flow of airflow inside the dust box 10.

[0063] On the basis of realizing automatic cleaning of the corresponding filter elements 15 by utilizing the fans 21 working at different times, by providing a rotatable filter upper cover 132 to cooperate with the mounting hole 1311, the second filter 152 and the first filter 151 can be disassembled regularly or irregularly for further or thorough cleaning. In addition, the provision of the mounting hole 1311 can also facilitate observation of the internal condition of the dust box 10, thereby facilitating inspection and repair.

[0064] For the exemplary structure of the dust box 10, the dust box 10 may be further provided with a buckle assembly 30 to facilitate the buckle connection between the dust box 10 and other devices. An example of the buckle assembly 30 of the dust box self-cleaning system 1 may be described in detail below.

[0065] like Figure 4 As shown, the buckle assembly 30 can be used to buckle with other devices, so that the dust box self-cleaning system 1 and other devices can be assembled and used. The other device is, for example, the device body of the cleaning device.

[0066] Specifically, the buckle assembly 30 may include a pressing portion 31, an elastic portion 33, and a buckle rod 32. The pressing portion 31 is connected to the buckle rod 32. For example, the buckle rod 32 may be an integral body, and the pressing portion 31 is connected to the middle area between the two ends of the buckle rod 32. The two ends of the buckle rod 32 are respectively protruded with buckle portions 321. Of course, if Figure 4 As shown, there can be two buckle rods 32, which are respectively connected to the two opposite sides of the pressing portion 31, one end of each buckle rod 32 is connected to the pressing portion 31, and the other end extends away from the pressing portion 31 and is provided with a buckle portion 321. When the dust box self-cleaning system 1 of this embodiment is buckled with other devices, for example, a buckle groove is correspondingly provided on the other device, and the buckle portion 321 is buckled and connected with the corresponding buckle groove.

[0067] The elastic portion 33 can be used to elastically support the pressing portion 31. The pressing portion 31 is elastically supported on the dust box 10 by the elastic portion 33. Figure 4As shown, the first housing 11 has a first placement groove 1110, the first placement groove 1110 corresponds to the notch 1213 of the second housing 12, the first placement groove 1110 and the side wall 112 of the first housing 11 extend in the same direction, the first placement groove 1110 can use part of the side wall 112 as its groove wall, that is, the opening direction of the first placement groove 1110 faces the cover body 13. The pressing portion 31 has a second placement groove 310, the extension direction of the second placement groove 310 is opposite or substantially opposite to the protruding direction of the buckle portion 321, and the elastic portion 33 can be a spring, one end of which extends into the first placement groove 1110 so as to be supported in the first placement groove 1110, and the other end can be exposed outside the first placement groove 1110. The other end of the elastic portion 33 is supported in the second placement groove 310. The size of the second placement groove 310 can be configured to accommodate the pressing portion 31, so that when the pressing portion 31 is pressed, it can be partially accommodated in the second placement groove 310.

[0068] like Figure 4 As shown, the other side of the second housing 12 may further be formed with a rod receiving groove 1212, which is spaced apart from the groove 1211. The buckle rod 32 may be received in the rod receiving groove 1212. When the buckle rod 32 is received in the rod receiving groove 1212, the position of the second housing 12 corresponding to the pressing portion 31 is a notch 1213. When the buckle rod 32 is received in the rod receiving groove 1212, the buckle portion 321 extends toward the cover body 13.

[0069] In this embodiment, when the second shell 12 and the cover body 13 are covered, the rod-containing groove 1212 and the channel cavity 130 can be isolated from each other and not connected to each other, so as to ensure that the suction force of the dust suction port 110 enables it to better absorb garbage objects. A buckle hole (not marked) is provided on the cover body 131 at the position corresponding to the buckle part 321. When the pressing part 31 is not pressed, the elastic part 33 is elastically supported between the first placement groove 1110 and the second placement groove 310, the buckle rod 32 is pushed against the top, and the buckle part 321 can protrude from the buckle hole so that it can be buckled and connected when assembled with other devices. When the pressing part 31 is pressed, the elastic part 33 is further elastically compressed, and the pressing part 31 can move toward the bottom wall 111, for example, it can move into the first placement groove 1110, and the buckle rod 32 moves away from the cover body 13 so that the buckle part 321 does not protrude from the buckle hole of the cover body 13 so that it can be disengaged. The buckle rod 32 can be limited by the rod receiving groove 1212, thereby limiting the pressing portion 31 from being pressed and continuing to move.

[0070] Of course, positioning posts (not shown) may be provided in both the first placement groove 1110 and the second placement groove 310 to position and fix the elastic portion 33 , for example, both ends of the spring are respectively sleeved on the positioning posts.

[0071] Of course, in addition to Figure 4In addition to the structure shown, the location of the communication port 140 can be adjusted by specifically designing the structures of the first shell 11, the second shell 12 and the cover 13, for example, the following situations can be considered:

[0072] like Figure 6 In the embodiment shown, the second shell 12a may include a top wall 121a and a side wall 122a, while the first shell 11a is arranged in a plate shape, and the cover 13a is covered on the first shell 11a, and the second shell 12a separates the accommodating chamber 100 and the channel chamber 130. Part of the plurality of communication ports 140 may be opened on the top wall 121a, and the other part may be opened on the side wall 122a. The partition plate 123 is arranged between the plurality of communication ports 140 to separate the plurality of communication ports 140 from each other, and the partition plate protrudes from the top wall 121a. When the cover 13a is covered on the first shell 11a, the partition plate 123 separates the channel chamber 130 into a plurality of channel sub-cavities 1310 that are independent of each other. For example, the partition plate 123 abuts against the side of the cover 13a facing the second shell 12a to separate the channel chamber 130 into a plurality of channel sub-cavities 1310 that are independent of each other. Each communication port 140 is connected to a channel sub-cavity 1310 and the accommodating cavity 100 . Of course, multiple communication ports 140 can also be opened on the side wall of the second shell 12a . The air outlet 120 can be opened on the cover 13a , and each air outlet 120 is connected to a channel sub-cavity 1310 .

[0073] like Figure 7In the embodiment shown, the first shell 11b includes a bottom wall 111b and a side wall 112b, and the second shell 12b is covered on the side wall 112b of the first shell 11b. The cover 13b is covered on the bottom wall 111b of the first shell 11b. The second shell 12b separates the accommodating chamber 100 and the channel chamber 130. At least one of the plurality of communication ports 140 is opened in the second shell 12b, and at least another one is opened in the side wall of the first shell 11b. The partition plate 123 may include a first partition plate 1231 and a second partition plate 1232. The first partition plate 1231 is arranged on the side of the cover 13b facing the second shell 12b, and the second partition plate 1232 is arranged on the side of the second shell 12b facing the cover 13b. And the second partition plate 1232 is arranged between the plurality of communication ports 140, for separating the plurality of communication ports 140. A groove (not marked) is provided on the side of the second partition 1232 facing the cover 13b. When the cover 13b is covered on the side wall 112b of the first shell 11b, the first partition 1231 is embedded in the groove of the second partition 1232 to separate the channel cavity 130 into a plurality of channel sub-cavities 1310 that are independent of each other. Of course, the groove can also be provided in the first partition 1231, and the second partition 1232 is embedded in the groove of the first partition 1231. Each communication port 140 corresponds to a communication port 1310 and a receiving cavity 100. Of course, a plurality of communication ports 140 can also be respectively provided on the opposite side walls of the first shell 11b.

[0074] The air outlet 120 may be provided on the cover 13b, and each air outlet 120 is connected to a corresponding channel sub-cavity 1310. Of course, when the second shell 12b is the second shell 12 in the exemplary structure of the dust box 10, the air outlet 120 may also be provided on the second shell 12. Optionally, a buckle hole may also be provided on the cover 13.

[0075] like Figure 8In the embodiment shown, the air outlet 120 can be arranged on the second shell 12c. Specifically, the second shell 12c includes a top wall 121c, a first side wall 122c and a second side wall 123c. Part of the first side wall 122c is arranged on the side of the second shell 12c facing the cover 13c, and another part of the first side wall 122c is arranged on the side of the second shell 12c facing the first shell 11c. The second side wall 123c is arranged on the side of the second shell 12c facing the first shell 11c. The second shell 12c is covered on the first shell 11c, and the first shell 11c, the second side wall 123c and the top wall 121c are arranged to form a receiving cavity 100. The cover 13c is covered on part of the first side wall 122c, and the top wall 121c, part of the first side wall 122c and the cover 13c are arranged to form a channel cavity 130. A plurality of communication ports 140 are arranged at intervals on the top wall 121c, and a partition plate 123 is arranged between the plurality of communication ports 140. The partition plate 123 protrudes from the top wall 121c and abuts against the cover body 13c to separate the plurality of communication ports 140 from each other, thereby separating the channel cavity 130 into a plurality of channel sub-cavities 1310 that are independent of each other. Each communication port 140 corresponds to a channel sub-cavity 1310 and the accommodating cavity 100. In addition, a portion of the second side wall 123c and the first side wall 122c form an air outlet 120. There can be a plurality of air outlets 120, and each air outlet 120 corresponds to a channel sub-cavity 1310.

[0076] like Fig. 9 In the embodiment shown, the air outlet 120 is provided on the cover 13d. For example, the first shell 11d includes a bottom wall 111d and a first side wall 112d. The first side wall 112d is located on the side of the bottom wall 111d facing the second shell 12d. The second shell 12d is covered on the first side wall 112d, and the bottom wall 111d, the first side wall 112d and the second shell 12d are arranged to form a receiving chamber 100. The cover 13d includes a top wall 131d and a second side wall 132d, and the second side wall 132d is located on the side of the top wall 131d facing the second shell 12d. The cover 13d is covered on the second shell 12d, and the second shell 12d, the second side wall 132d and the top wall 131d are arranged to form a channel chamber 130. A plurality of communication ports 140 are arranged at intervals on the second shell 12d, and a partition plate 123 is protruded from the side of the cover 13d facing the second shell 12d. The partition plate 123 abuts against the side of the second shell 12d facing the cover 13d, and the abutting part is located between the multiple communication ports 140 to separate the multiple communication ports 140 from each other, thereby separating the channel cavity 130 into multiple independent channel sub-cavities 1310, each communication port 140 correspondingly connects a channel sub-cavity 1310 and the accommodating cavity 100. Multiple air outlets 120 are provided on the second side wall 132d, and each air outlet 120 correspondingly connects to a channel sub-cavity 1310.

[0077] Taking a sweeping robot as an example, the sweeping robot (not shown) includes a device body (not shown) and a dust box self-cleaning system 1 of this embodiment, and the dust box self-cleaning system 1 is connected to the device body. The device body is used for cleaning, for example, cleaning the floor.

[0078] Specifically, for example, the device body includes a shell, a roller brush arranged on the shell, and a driving motor for driving the roller brush to roll. The device body can be used in conjunction with the dust box self-cleaning system 1 of this embodiment. For example, a buckle groove (not shown) is provided on the shell of the device body, which is buckled with the buckle part 321. Specifically, when pressure is applied to the pressing part 31, the elastic part 33 produces elastic deformation, and the pressing part 31 can drive the buckle part 321 to move away from the buckle groove, so that the buckle part 321 can be disengaged from the buckle groove. When pressure is not applied to the pressing part 31, the elastic restoring force of the elastic part 33 can enable the pressing part 31 to drive the buckle part 321 to move close to the buckle groove or maintain a state close to the buckle groove, so that the buckle part 321 can be buckled with the buckle groove.

[0079] This embodiment can be easily connected to the main body of the cleaning device by providing a buckle assembly 30. In some embodiments, the buckle assembly 30 includes two buckle parts 321, which can make the buckle connection between the dust box self-cleaning system 1 of this embodiment and the main body of the device tighter, enhance the fixing effect of the two structures, and the provision of the two buckle parts 321 can further limit the relative displacement of the dust box 10 and the shell of the main body of the device, ensuring the stability of the structure.

[0080] The connector 22 of the dust collection assembly 20 of this embodiment can be fixed to the housing of the device body. The good snap-on effect and limiting effect of the snap-on assembly 30 prevent the dust box 10 and the device body from shifting, thus effectively ensuring the sealing effect of the connector 22 and the air outlet 120.

[0081] In order to further enhance the speed of airflow and optimize the design of the structural space, this embodiment provides an exemplary structure of the connecting member 22 as follows:

[0082] See also Fig.10 The connector 22 of this embodiment may have an irregular shape. A first vent 221 may be formed on one side of the connector 22, and the first vent 221 is used to communicate with the air outlet 120. A second vent 222 communicated with the first vent 221 is formed on the other side of the connector 22. The shape of the first vent 221 may be adapted to the shape of the air outlet 120, or may be designed according to specific circumstances. For example Fig.10 The shape of the first vent 221 is similar to Figure 1-Figure 4 The shape of the air outlet 120 shown is adapted. Fig.10The first vent 221 shown can be Figure 1-4 The air outlet 120 shown is designed in a specific shape so that the two can adapt to each other. In this embodiment, the shapes of the connecting member 22 and the first air outlet 221 are not limited, and the same is true for the second air outlet 222.

[0083] For example, the first vent 221 opened on one side of the connecting member 22 and the second vent 222 opened on the other side of the connecting member 22 can be staggered. For example, after the connecting member 22 is assembled with the dust box 10, the projection of the first vent 221 on the plane where the air outlet 120 is located and the projection of the second vent 222 on the plane where the air outlet 120 is located can partially overlap or not overlap at all. The connecting member 22 has a space inside, which is connected to the first vent 221 and the second vent 222 respectively. In this way, the path of the airflow flowing in the connecting member 22 can be curved.

[0084] In this embodiment, the angle between the plane where the first vent 221 is located and the plane where the second vent 222 is located is greater than 0° and less than 180°. Optionally, the angle between the plane where the first vent 221 is located and the plane where the second vent 222 is located is greater than or equal to 20° and less than 100°. Optionally, the angle between the plane where the first vent 221 is located and the plane where the second vent 222 is located is greater than or equal to 30° and less than or equal to 90°. Optionally, the angle between the plane where the first vent 221 is located and the plane where the second vent 222 is located is greater than or equal to 40° and less than or equal to 60°. Optionally, the angle between the plane where the first vent 221 is located and the plane where the second vent 222 is located is 46°.

[0085] The fan 21, for example, an exhaust fan or a blower, can achieve the function of exhausting air. The fan 21 is arranged on the other side of the connecting member 22 and is connected to the second vent 222. When the fan 21 is working, the airflow passes through the dust suction port 110, the accommodating cavity 100, the channel cavity 130, the space of the extension part 122, the air outlet 120, the first vent 221 and the second vent 222 in sequence, and is extracted by the fan 21.

[0086] like Figure 2 As shown, in this embodiment, when the connector 22 is connected to the air outlet 120, it can be sealed by a sealing ring 24, and the sealing ring 24 is, for example, a sealing rubber ring. That is, the sealing ring 24 can be provided at the connection between the first vent 221 and the air outlet 120 to seal the connection.

[0087] This embodiment can optimize the air duct design of the entire dust box self-cleaning system 1 by setting the ventilation structure of the connecting member 22 and the angle between the plane where the first vent 221 is located and the plane where the second vent 222 is located, so that the airflow speed is faster. In addition, the angle between the plane where the first vent 221 is located and the plane where the second vent 222 is located can make the fan 21 have a certain inclination when installed (such as Figure 1 As shown), the installation space of the fan 21 can be effectively saved.

[0088] like Figure 2 As shown, the dust collection assembly 20 of this embodiment may further include a shock-absorbing pad 23, and a receiving groove 223 is formed on the other side of the connecting member 22 having the second vent 222, the receiving groove 223 is connected to the second vent 222, and the shape of the receiving groove 223 is adapted to the shape of the shock-absorbing pad 23, and the shock-absorbing pad 23 is received in the receiving groove and is located between the fan 21 and the connecting member 22.

[0089] In this embodiment, a receiving groove 223 is provided to accommodate the shock-absorbing pad 23. The fan 21 is arranged on the connecting member 22 through the shock-absorbing pad 23, which can effectively reduce the vibration of the fan 21 during operation, thereby effectively reducing the impact of the vibration of the fan 21 on the connecting member 22, and can effectively ensure the sealing effect of the connecting member 22 and the dust box 10, thereby ensuring the exhaust effect of the fan 21.

[0090] The dust box assembly provided in the dust box assembly embodiment of the present application can refer to the description of the dust box assembly in the above-mentioned embodiment of the dust box self-cleaning system 1 of the present application, which will not be repeated here.

[0091] The cleaning device described in the cleaning device embodiment of the present application is, for example, the aforementioned sweeping robot or vacuum cleaner, but is not limited to the sweeping robot and vacuum cleaner. Fig.11 The cleaning device 300 of this embodiment includes: a device body 2 and the dust box self-cleaning system 1 described in the above embodiment. The dust box self-cleaning system 1 is connected to the device body 2. For example, a buckle hole for buckling with the buckle part 321 can be provided on the device body 2, so that the buckle part 321 in the dust box self-cleaning system 1 is inserted into the buckle hole and buckled with the device body.

[0092] The device body 2 may include a controller 210. The controller 210 may be an MCU, or a control circuit component including an MCU. The controller 210 is coupled to the multiple fans 21 to control the working mode of the cleaning device 300, and the working mode includes a self-cleaning mode and a cleaning and dust removal mode. When the cleaning device 300 is controlled to be in the self-cleaning mode, the controller 210 controls some fans 21 to work while the remaining fans 21 are not working, so as to clean the filter elements 15 corresponding to the remaining fans 21. When the cleaning device 300 is controlled to be in the cleaning and dust removal mode, the controller 210 controls all fans 21 to work, thereby cleaning and dust removal and other operations are performed on the working surface (e.g., the ground) of the cleaning device 300.

[0093] If the cleaning device 300 is a vacuum cleaner, the device body 2 may also include a housing, a circuit board, etc., and may also include a floor brush, which is connected to the housing through an air duct. The dust box self-cleaning system 1 may be arranged in the housing of the device body 2, and is used to absorb debris, dust, etc. through the floor brush and the air duct.

[0094] If the cleaning device 300 is a sweeping robot, the device body 2 includes, for example, a housing, a roller brush, and a motor for driving the roller brush to roll. The roller brush is used to sweep garbage, debris, dust, etc., and the dust box self-cleaning system 1 is used to absorb the garbage, debris, dust, etc. swept by the roller brush.

[0095] The self-cleaning process of the cleaning device of the present application can be automatically controlled by software. The specific control method can be as follows:

[0096] like Fig.12 As shown, the dust box self-cleaning method embodiment of the present application may include the following steps:

[0097] S100: Control at least one fan to not work, and control at least another fan to work.

[0098] Among the multiple fans 21, by controlling at least one fan 21 not to work and at least another fan to work, the working fan 21 can clean the filter element 15 corresponding to the non-working fan 21, thereby achieving self-cleaning.

[0099] In order to improve the working efficiency of the cleaning device 300 and to utilize the idle time of the cleaning device 300 to achieve self-cleaning, it is possible to determine whether the cleaning device 300 is in a stopped state before S100, as follows:

[0100] S200: Determine whether the cleaning device 300 is in a stopped state including a charging state.

[0101] When the cleaning device 300 is in a charging state, it generally does not perform cleaning work. For example, the cleaning device 300 is a sweeping robot. When the power is insufficient, it can return to the charging stand for charging according to the guidance of the charging stand, and the fan 21 is generally in a non-working state. When the cleaning device 300 is not in a charging state, it may be in a working state, or a preparatory state before entering the working state, or a short sleep state, or a fault state, or an idle state. In addition to the charging state, the stop state may be a state in which the cleaning device 300 is not working or moving, for example, it may include a preparatory state, a short sleep state, a fault state or other idle states. If it is determined that the cleaning device 300 is in a stop state, S100 is executed. If it is determined that the cleaning device 300 is not in a stop state, S400 may be executed.

[0102] In order to achieve more effective self-cleaning, multiple fans may be controlled to start alternately, which may be specifically achieved through the following steps included in S100.

[0103] S300: Control multiple fans to start alternately, so as to control some fans and other fans to work alternately at intervals of preset time.

[0104] In this embodiment, alternating operation means that when some fans 21 are working, the other fans 21 are not working, and when the other fans 21 are working, some fans 21 are not working. After some fans 21 are working and the other fans 21 are not working for a preset time, the other fans 21 are working and some fans 21 are not working alternately, and after the other fans 21 are working and some fans 21 are not working for a preset time, some fans 21 can be working and the other fans 21 can be not working alternately, so that some fans 21 and the other fans 21 can be controlled to work alternately at intervals of a preset time, and the cleaning device 300 enters the self-cleaning mode. Some fans 21 refer to at least one fan 21, and the other fans 21 also include at least one fan 21.

[0105] By controlling multiple fans 21 to start alternately, it is possible to control some fans 21 and the remaining fans 21 to work alternately at intervals of preset time. The fans 21 that work in this way can form a reverse airflow in the dust box that passes through the air outlet, channel sub-cavity and connecting port corresponding to the remaining fans 21 that are not working, thereby cleaning the filter elements corresponding to the remaining fans 21 that are not working.

[0106] S400: Control multiple fans to start or shut down.

[0107] When the cleaning device 300 is not in a charging state, all fans 21 can be controlled to start, that is, all fans 21 are working, and the cleaning device 300 enters a cleaning and dust removal mode. When the cleaning device 300 is not in a charging state, all fans 21 can also be controlled to be turned off, so that the cleaning device 300 enters a suspended state or a temporarily dormant state. Of course, in other embodiments, when the cleaning device 300 is not in a charging state, the cleaning device 300 can also be set to enter a self-cleaning mode.
