[0037] The realization, functional features and advantages of the objectives of the present invention will be further described in conjunction with the embodiments and with reference to the accompanying drawings. Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without any creative efforts shall fall within the protection scope of the present invention.

[0039] It should be noted that all directional indications (such as up, down, left, right, front, back,...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0040] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0041] In addition, in the embodiments of the present invention, the descriptions involving "first", "second", etc. are only for descriptive purposes, and cannot be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0042] In addition, in the embodiments of the present invention, the term "dust" generally refers to cat hair, dust, etc. mixed in the cat litter after being used by a pet cat.

[0043] An existing cleaning system includes a sweeping robot and a dust collection device. The dust collection device only provides two functions: on the one hand, it recovers dust, hair, etc. in the dust box inside the sweeping robot, and on the other hand, it charges the sweeping robot. Specifically, the sweeping robot automatically travels on the ground, sucks dust, hair, etc. on the ground into the dust box inside the sweeping robot. After the dust box is full, the sweeping robot can automatically navigate back to the dust collection device and discharge the dust in the dust box into the dust collection device. Moreover, when the sweeping robot needs to charge its internal battery, it will also automatically navigate back to the dust collection device and be charged by the dust collection device.

[0044] In view of this, the present invention provides a dust collection device and a cleaning system. The cleaning system includes a dust collection device. Through the cooperation among a first container, a first channel, an air flow driving mechanism, and a disinfection mechanism provided, the dust collection device can automatically transfer the cat litter used by a pet cat and containing dust from the cat litter basket to the first container, separate the dust from the cat litter, sterilize, disinfect, and deodorize it, and then automatically transfer the cat litter after dust separation, sterilization, disinfection, and deodorization back to the cat litter basket, realizing the reuse of the cat litter, reducing the household cost, and also realizing the expansion of the functions of the dust collection device, which is more conducive to market promotion and sales.

[0045] Such as Figure 1 , Figure 2 , Figure 3As shown in the figure, a dust collection device 100 provided by an embodiment of the present invention includes a main body 10, a first container 11, a first channel 15, an air flow driving mechanism 13, and a disinfection mechanism 14. The first container 11 is provided in the main body 10 and is used to contain cat litter 200. The first channel 15 is provided in the main body 10 and has a first end 151 and a second end 152. The first end 151 is used to communicate with the first container 11. The air flow driving mechanism 13 is provided in the main body 10 and is used to generate an air flow, and the air flow can be used to drive the cat litter 200 to enter the first channel 15 through the second end 152 and be transferred to the first container 11. The disinfection mechanism 14 is provided in the main body 10 and is used to sterilize, disinfect, and deodorize the cat litter 200.

[0046] Understandably, by using the dust collection device 100, the cat litter 200 in the cat litter basket 400 can be automatically transferred to the first container 11 of the dust collection device 100, then the dust 300 is separated from it, and it is sterilized, disinfected, and deodorized, and then it can be automatically transferred back to the cat litter basket 400 for the pet cat to use again, realizing the recycling of the cat litter 200, which is beneficial to reducing the cost of raising pets and can also expand the functions of the dust collection device 100.

[0047] Specifically, when it is necessary to transfer the cat litter 200 in the cat litter basket 400 to the first container 11, if the cat litter basket 400 is provided with a cat litter transfer port (not shown), only need to place the cat litter basket 400 on the dust collection device 100, dock the cat litter transfer port of the cat litter basket 400 with the second end 152 of the first channel 15, and then start the air flow driving mechanism 13. The air flow driving mechanism 13 will generate an air flow, and the cat litter 200 in the cat litter basket 400 will enter the first channel 15 through the second end 152 and be transferred to the first container 11. If the cat litter basket 400 has no such cat litter transfer port, one end of a hose 500 can be docked with the second end 152 of the first channel 15, and the other end of the hose 500 can be placed in the cat litter basket 400. When the air flow driving mechanism 13 is started, the cat litter 200 in the cat litter basket 400 will also be driven by the air flow and be transferred to the first container 11 through the hose 500 and the first channel 15. When the treatment of the cat litter 200 is completed, that is, the dust 300 is separated from it and it is sterilized, disinfected, and deodorized, then the treated cat litter 200 can be transferred back to the cat litter basket 400. It eliminates the trouble of manually taking out the cat litter 200 in the cat litter basket 400 and then pouring it into the first container 11. In addition, through the dust collection device 100, the dust 300 is separated from the cat litter 200, and it is sterilized, disinfected, and deodorized, realizing the reuse of the cat litter 200. Figure 2 、 Figure 3It is shown that one end of the hose 500 is connected to the second end 152 of the first channel 15, and then the other end of the hose 500 is placed in the cat litter basket 400. Among them, Figure 2 Specifically, it is a situation where the cat litter 200 in the cat litter basket 400 is automatically transferred to the first container 11 by using the air flow; Figure 3 Specifically, it is to automatically transfer the cat litter 200 back to the cat litter basket 400 by using the gravity of the cat litter 200.

[0048] Please further refer to Figure 4 、 Figure 5 and Figure 6 , in some embodiments, a waterproof and breathable first filter element 111 is provided at the bottom of the first container 11, forming a downward slope from the middle to the edge. Under the action of the air flow, the first filter element 111 forms an upward slope from the middle to the edge. A first valve 1110 is provided on the first filter element 111, and the first valve 1110 is connected to the first end 151 of the first channel 15. When the first valve 1110 is opened, the cat litter 200 can pass through.

[0049] Specifically, the bottom of the first container 11 is fully open, the first filter element 111 can be a flexible waterproof and breathable membrane, and the overall size is larger than the bottom size of the first container 11. The first valve 1110 is provided at the middle position of the first filter element 111. By fixedly installing the four peripheral edges of the first filter element 111 on the four peripheral edges of the bottom of the first container 11. Under the gravity of the first filter element 111 and the first valve 1110, the first filter element 111 forms a downward slope from the edge of the first valve 1110 to the edge of the bottom of the first container 11, having a first downward slope angle α1 and a second downward slope angle α2, and the first downward slope angle α1 and the second downward slope angle α2 can be the same or different. In some embodiments, the first downward slope angle α1 and the second downward slope angle α2 are the same and are between 30° and 45°.

[0050] The first valve 1110 can be circular, rectangular or square, and there is no limitation here. At least in some embodiments, the first valve 1110 is circular. A circular cutout matching the shape and size of the first valve 1110 can be opened at the middle position of the first filter element 111, and then the first valve 1110 can be fixedly installed on the first filter element 111. The first valve 1110 has a structure similar to a door hinge, including a connecting shaft 1112, two identical rotating blades 1111 and an elastic member (not shown). The two rotating blades 1111 can rotate around the connecting shaft 1112, and the elastic member connects the two rotating blades 1111. Without external force, the two rotating blades 1111 are kept open and symmetric under the action of the elastic member, so that the first valve 1110 is in a closed state. A small amount of the cat litter 200 is carried on any one of the rotating blades 1111, and this rotating blade 1111 rotates downward and opens under the gravity of the small amount of the cat litter 200. The quantity of the cat litter 200 can be determined according to specific needs, such as 10 or 15 pieces of the cat litter 200, and then a suitable elastic member can be selected. The smaller the quantity, the more sensitive the first valve 1110 is, and there is no limitation here. Under the action of the air flow, both of the rotating blades 1111 can rotate upward and open. Under the action of the air flow, the two rotating blades 1111 of the first valve 1110 open upward, and at the same time, the first filter element 111 forms an upward slope from the edge of the first valve 1110 to the edge of the bottom of the first container 11, having a first upward slope angle β1 and a second upward slope angle β2. The first upward slope angle β1 and the second upward slope angle β2 can be the same or different. In some embodiments, the first upward slope angle β1 and the second upward slope angle β2 are the same and are between 30° and 45°.

[0051] When it is necessary to transfer the cat litter 200 in the cat litter basket 400 to the first container 11, dock the cat litter transfer opening of the cat litter basket 400 with the second end 152 of the first channel 15, and start the air flow driving mechanism 13. The cat litter 200 in the cat litter basket 400 will be driven by the air flow and enter the first container 11 through the first channel 15 and the first valve 1110. At the same time, under the action of the air flow, the first filter element 111 forms the first upward slope angle β1 and the second upward slope angle β2. When the cat litter 200 entering the first container 11 falls, it will tend to accumulate at the four peripheral edges of the first container 11. When the separation, disinfection, and deodorization of the dust 300 in the cat litter 200 are completed, stop the air flow driving mechanism 13. The first valve 1110 is opened under the gravity of a small amount of the cat litter 200. At the same time, the first filter element 111 forms the first downward slope angle α1 and the second downward slope angle α2. The cat litter 200 will be transferred back to the cat litter basket 400 through the first channel 15 under its own gravity until the first valve 1110 closes, completing the automatic transfer of the cat litter 200 back to the cat litter basket 400. Since the first valve 1110 only needs a small amount of the cat litter 200 to open, almost all of the cat litter 200 in the first container 11 can be automatically transferred back to the cat litter basket 400 under its own gravity, eliminating the need for manual handling of the cat litter 200, which is very convenient.

[0052] In some other embodiments, the first valve 1110 is an electronically controlled open valve, which is in a closed state under normal conditions and is automatically opened through the dust collection device 100. For example, when it is necessary to transfer the cat litter 200 in the cat litter basket 400 to the first container 11, the first valve 1110 can be operated to open upward. When it is necessary to transfer the cat litter 200 from the first container 11 to the cat litter basket 400, the first valve 1110 can be operated to open upward.

[0053] In addition, the first filter element 111 is waterproof and can prevent the moisture in the cat litter 200 (mainly the moisture contained in the excrement of pet cats) from leaking to the main body 10, avoiding damage to the dust collection device 100.

[0054] Please refer to again Figure 1 、 Figure 4 、 Figure 5 and Figure 6, in some embodiments, the first channel 15 includes a telescopic section 150, which is disposed near the first end 151. The first end 151 is connected to the first valve 1110. The outer peripheral portion of the telescopic section 150 is provided with ventilation holes (not shown) through which only the airflow can pass. Specifically, the telescopic section 150 can be a flexible film with ventilation holes on the outer periphery that only allow the airflow to pass, and is disposed near the first end 151. The telescopic section 150 forms at least one fold 1500 in the radial direction, which helps the first filter element 111 to form the first downward slope angle α1 and the second downward slope angle α2. When the first filter element 111 forms the first upward slope angle β1 and the second upward slope angle β2 under the action of the airflow, at least one of the folds 1500 unfolds. In some other embodiments, the telescopic section 150 has a structure similar to a telescopic antenna rod. When the first filter element 111 forms the first downward slope angle α1 and the second downward slope angle α2, a part of the telescopic section 150 extends into other parts. Similarly, when the first filter element 111 forms the first upward slope angle β1 and the second upward slope angle β2, the extended part of the telescopic section 150 is pulled out. By connecting the first end 151 to the first valve 1110 and the telescopic section 150, it is possible to prevent the cat litter 200 from entering other parts of the main body 10 except the first container 11 during the transfer process. Among them, Figure 4 shows at least one of the folds 1500 in some embodiments, Figure 5 shows the situation where at least one of the folds 1500 is fully unfolded in some embodiments, Figure 6 shows the situation where the telescopic section 150 adopts a structure similar to a telescopic antenna rod in some embodiments.

[0055] Please refer to again Figure 2 、 Figure 4 、 Figure 5 and Figure 6 , in some embodiments, the dust collection device 100 further includes a second container 12 disposed on the main body 10. The second container 12 is provided with a first inlet 121, and the first container 11 is provided with a first outlet 112 communicating with the first inlet 121. The first outlet 112 or / and the first inlet 121 allows the dust 300 to pass through and blocks the cat litter 200 from passing through. During the process of transferring the cat litter 200 from the cat litter basket 400 to the first container 11, most of the dust 300 will enter the first container 11 under the action of the airflow.

[0056] The currently commonly used cat litter 200300 has a particle diameter size of 1 - 5 mm, the diameter of cat hair is generally 0.02 mm - 0.06 mm, and the diameter size of dust is less than 0.5 mm.

[0057] Specifically, on one side of the first container 11, long holes 1121 with a certain size of spacing (such as 0.8 - 4.8 mm) are directly processed in one or multiple directions to form the first outlet 112, so that only dust 300 can pass through and cat litter 200 cannot pass through. An incision is made on one side of the second container 12 to form the first inlet 121, and the first inlet 121 communicates with the first outlet 112.

[0058] In some embodiments, the first outlet 112 allows the cat litter 200 to pass through. On one side of the second container 1212, the long holes 1121 with a certain size of spacing (such as 0.8 - 4.8 mm) are directly processed in one or multiple directions to form the first inlet 121, so that only dust 300 can pass through and cat litter 200 cannot pass through. There is no limitation here.

[0059] In some embodiments, a second filter member 1120 is provided at the first outlet 112 of the second container 12, and the second filter member 1120 is used for allowing the dust 300 to pass through and blocking the cat litter 200 from passing through.

[0060] Specifically, the first outlet 112 can be formed by starting on one side of the first container 11, and the cross-section of the first outlet 112 is circular. In other embodiments, the cross-section of the first outlet 112 can be square or rectangular (not shown), and there is no limitation here. Then, a second filter member 1120 that matches the shape of the first outlet 112 is detachably installed. The second filter member 1120 is provided with the long holes 1121 with a certain size of spacing (such as 0.8 - 4.8 mm) in one or multiple directions, so as to achieve that only the dust 300 can pass through and the cat litter 200 is blocked. Therefore, the corresponding second filter member 1120 can be matched according to the actual use of the cat litter 200. For example, if the diameter of the selected cat litter 200 is 3 mm, the second filter member 1120 with the spacing of the long holes 1121 less than 3 mm can be selected, and other sizes can be analogized. In the case of using the second filter member 1120, only the second filter member 1120 may need to be replaced when changing different cat litters 200. Therefore, the method of using the second filter member 1120 is better in terms of use cost and convenience. The second filter member 1120 can be detachably installed at the first outlet 112 by means of snap fasteners, mounting grooves, Velcro, etc., and there is no limitation here. Due to space limitations, only the case where the long holes 1121 are arranged in one direction is shown here. Figure 4 、 Figure 5 、 Figure 6 Only the case where the long holes 1121 are arranged in one direction is shown.

[0061] Please refer toFigure 2 During the process of transferring the cat litter 200 in the cat litter basket 400 to the first container 11, under the action of the air flow, both the cat litter 200 and the dust 300 will move towards the first outlet 112. Since only the dust 300 can pass through the first outlet 112, the cat litter 200 will collide with the long strip holes 1121 at the first outlet 112 and then fall to the bottom of the first container 11. The agglomerated cat litter 200 will be broken up and fall to the bottom of the first container 11. The dust 300 will then pass through the first outlet 112 and the first inlet 121 in sequence to enter the second container 12 and be collected in the second container 12, thereby realizing the separation of the dust 300 and breaking up the agglomerated cat litter 200.

[0062] When the air flow driving mechanism 13 is working, the disinfection mechanism 14 can be started to sterilize, disinfect and deodorize the cat litter 200 transferred into the first container 11. While transferring the cat litter 200 from the cat litter basket 400 to the first container 11, the cat litter 200 already accommodated in the first container 11 can be sterilized, disinfected and deodorized at the same time.

[0063] In some embodiments, after the transfer of the cat litter 200 from the cat litter basket 400 to the first container 11 is completed, the first valve 1110 can be controlled to close, and the air flow driving mechanism 13 can be turned off or still kept working, and at the same time the disinfection mechanism 14 is started to sterilize, disinfect and deodorize the cat litter 200. There is no limitation here.

[0064] Please refer to Figure 2 、 Figure 7 In some embodiments, a dust bag 123 is detachably installed at the first inlet 121. The dust bag 123 is a bag-like structure with an opening at one end. The dust bag 123 can collect the dust 300 (i.e., not allowing the dust 300 to pass through) and allow the air flow to pass through. The material can be cotton cloth, non-woven fabric, microfiber material, HEPA material, etc., and there is no limitation here. When the dust bag 123 is full of the dust 300, the dust bag 123 can be detached therefrom, and then a new dust bag 123 can be installed at the first inlet 121, or the garbage in the dust bag 123 can be poured out and then reinstalled at the first inlet 121. It can be understood that the dust bag 123 is a consumable, which can be purchased separately. It is folded when not in use and occupies little space. It will expand under the action of the air flow during use and collect the dust 300. After being full of dust, it can be taken out from the second container 12 and thrown into the trash can, which is hygienic and convenient.

[0065] Please refer here to Figure 2, in some embodiments, the air flow driving mechanism 13 is a negative pressure fan. A second outlet 122 is provided at the bottom of the second container 12, and the air inlet end (not shown) of the negative pressure fan is provided at the second outlet 122.

[0066] Specifically, the second end 152 of the first channel 15 can be used for allowing external air to enter, for docking with the cat litter basket 400, for docking with the hose 500, etc. The negative pressure fan can be disposed close to the second outlet 122. The second outlet 122 is used for allowing the air flow to pass through and blocking the dust 300 from passing through. During operation, the negative pressure fan sucks away the air near the second outlet 122 and generates a negative pressure inside the second container 12. External air will enter from the second end 152 of the first channel 15, and then successively pass through the first end 151 of the first channel 15, the first valve 1110 and the first filter element 111, the inside of the first container 11, the first outlet 112, the first inlet 121, and the first outlet 112 to form the air flow. Thus, when the cat litter basket 400 is in communication with the second end 152 of the first channel 15 (directly docked and communicated or communicated through the hose 500), the air flow will drive the cat litter 200 to enter the first container 11 from the cat litter basket 400 through the first channel 15 and the first valve 1110, thereby separating the dust 300 from the cat litter 200 and driving the dust 300 into the dust bag 123.

[0067] At least in some embodiments, the second outlet 122 is formed by the inward concavity of the second container 12. The air inlet end of the negative pressure fan correspondingly extends into the second container 12, which is more conducive to forming a negative pressure inside the second container 12, thereby improving the effect of separating the dust 300.

[0068] The second outlet 122 can be a series of ventilation holes for only allowing the air flow to pass through, so as to allow the air flow to pass through and block the dust 300. It can also be realized by opening an opening in the bottom of the second container 12 that matches the shape of the air inlet end of the negative pressure fan, and then installing a filter net that only allows the air flow to pass through at the second outlet 122 to allow the air flow to pass through and block the dust 300. It can also be realized by detachably installing a HEPA at the second outlet 122. Here, HEPA is the abbreviation of High Efficiency Particulate Air Filter, which is a high-efficiency air filter. Its fibers are very fine and interweave into a complex network structure, which can filter very fine particles of the dust 300 and allow the air to pass through, thereby preventing fine particles from entering the negative pressure fan. There is no limitation here.

[0069] Please participate Figure 1 and Figure 7 、 Figure 8 In some embodiments, the main body 10 further includes a cover 16. The first container 11 and the second container 12 are respectively provided with a first opening end 110 and a second opening end 120. When the cover 16 is closed, the first opening end 110 and the second opening end 120 are covered. The disinfection mechanism 14 includes at least one UV lamp 140 provided on the cover 16. When the cover 16 is closed, the at least one UV lamp 140 is close to or located at the first opening end 110. The full name of UV is Ultraviolet, that is, ultraviolet light, which can be used for sterilization, disinfection and deodorization. The at least one UV lamp 140 is a lamp that can emit ultraviolet light for sterilization, disinfection and deodorization.

[0070] Specifically, the cover 16 is provided with two rotating parts 161 and is rotatably mounted on the main body 10 through the two rotating parts 161. The cover 16 can be rotatably closed on one end of the main body 10, which is convenient for the cover 16 to be opened and closed. The first opening end 110 and the second opening end 120 are respectively opposite to the one filter element 111 and the second outlet 122. When the cover 16 is closed, the first opening end 110 and the second opening end 120 can be covered. The first opening end 110 and the second opening end 120 can be respectively the top part opening or full opening of the first container 11 and the second container 12, and there is no limitation here. At least in some embodiments, the second opening end 120 is a full opening, which is more conducive to the installation and disassembly of the dust bag 123.

[0071] Specifically, at least one UV lamp 140 is installed on the cover 16, and at least one UV lamp 140 is close to or located at the first opening end 110. During operation, ultraviolet light is emitted downward into the first container 11 to sterilize, disinfect and deodorize the cat litter 200 contained in the first container 11. The at least one UV lamp 140 and the air flow driving mechanism 13 work simultaneously, that is, separating the dust 300 and sterilizing, disinfecting and deodorizing the cat litter 200 at the same time, or after the air flow driving mechanism 13 finishes working, that is, after separating the dust 300 from the cat litter 200, then controlling the at least one UV lamp 140 to work to sterilize, disinfect and deodorize the cat litter 200. The sterilization, disinfection and deodorization effect can be improved by uniformly or non-uniformly arranging multiple groups of the UV lamps 140 at the part of the cover 16 corresponding to the first opening end 110. In addition, at least one UV lamp 140 is arranged on the cover 16, which is convenient for maintenance and installation.

[0072] Please refer to Figure 9, an embodiment of the present invention further provides a cleaning system 1000, including the above-mentioned dust collection device 100 and a floor sweeper 600. The floor sweeper 600 includes a dust box 610, a charging terminal 620, and a dust discharge port 630. When the floor sweeper 600 docks with the dust collection device 100, the dust collection device 100 can charge the floor sweeper 600 through the charging terminal 620 and / or transfer the garbage in the dust box 610 to the dust collection device 100 through the discharge port.

[0073] Understandably, the floor sweeper 600 relies on the battery inside itself to travel and work on the ground, sucking garbage such as waste paper scraps, hair, and dust on the ground into the dust box 610. When the battery power is insufficient during the working process or the dust box 610 is full (i.e., filled with garbage), it will automatically navigate back to the dust collection device 100 and dock with the dust collection device 100. If the battery of the floor sweeper 600 is insufficient and needs to be charged, the dust collection device 100 will charge the battery of the floor sweeper 600 by using the household municipal electricity through the charging terminal 620. If the dust box 610 of the floor sweeper 600 is full, the dust collection device 100 controls the air flow driving mechanism 13 to generate an air flow. The garbage in the dust box 610 will be discharged to the dust collection device 100 through the dust discharge port 630 under the action of the air flow.

[0074] Next, in combination with Figures 1 to 9 Some embodiments provided by the present invention are used to elaborate on the principle of the dust collection device 100 recycling the garbage in the dust box 610 of the floor sweeper 600, and the principle of the dust collection device 100 charging the floor sweeper 600.

[0075] First, place the dust collection device 100 against the wall on the floor of the living room or bedroom, connect the dust collection device 100 to the socket of the household municipal electricity, and take out and store the first container 11. When used for the first time, the floor sweeper 600 can be connected through the mobile phone APP. Then manually place the floor sweeper 600 on the dust collection device 100 and dock it with the dust collection device 100, or operate and control the floor sweeper 600 to dock with the dust collection device 100 through the mobile phone APP. The floor sweeper 600 will take the position where the dust collection device 100 is located as the initial position of the floor sweeper 600.

[0076] Then, the sweeper 600 can be controlled by a mobile phone APP to work automatically at a fixed time. When working, the sweeper 600 will walk on the ground in a preset manner and suck various kinds of garbage such as shredded paper, hair, and dust on the ground into the dust box 610. When the sweeper 600 detects that the dust box 610 is full, the sweeper 600 will automatically navigate back to the position where the dust collection device 100 is placed and dock with the dust collection device 100. The discharge port of the sweeper 600 will be docked with the second end 152 of the first channel 15 of the dust collection device 100. The negative pressure fan of the dust collection device 100 works to generate negative pressure in the second container 12, thereby generating the air flow. The garbage in the dust box 610 will be discharged from the sweeper 600 through the dust discharge port 630, and then will be collected in the dust bag 123 successively through the first channel 15 and the first inlet 121 along with the air flow. Generally, the capacity of the dust bag 123 is several times or even dozens of times that of the dust box 610. By recycling the garbage in the dust box 610 of the sweeper 600 through the dust collection device 100, the trouble of frequently taking out the dust box 610 from the sweeper 600 and then pouring the garbage into the trash can is eliminated.

[0077] When the sweeper 600 detects insufficient power or power lower than a certain level (such as 15% of the battery capacity, which can also be set to other values according to needs) during operation, the sweeper 600 will automatically navigate back to the dust collection device 100 and dock with the dust collection device 100. Then, the dust collection device 100 will charge the battery of the sweeper 600 using household municipal electricity through the charging terminal 620. When the battery of the sweeper 600 is fully charged, the dust collection device 100 automatically controls to stop charging the sweeper 600. The sweeper 600 can return to the position where it last cleaned and continue cleaning, or start cleaning again, or continue to dock with the dust collection device 100 without cleaning. The sweeper 600 will also automatically return to dock with the dust collection device 100 after each operation.

[0078] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
