[0019] Through the above arrangement, the cleaning device only needs one dust collection cover plate to form the dust collection duct, compared with the scheme of two cover plates in the prior art, the number of structures required for the dust collection duct can be reduced, and the cost can be reduced. In addition, in the prior art, two cover plates first need to be connected to form a duct, and then the connected structure is mounted on the base, which needs multiple positioning and multiple connection. The dust collection duct provided by the embodiment of the present application only needs one positioning and one connection to form the dust collection duct, which can reduce the assembly process and thereby improve the assembly efficiency.

[0020] In the cleaning device, optionally, the base is made of the same material as the dust collecting cover plate.

[0021] By using the same material, the consistency of the base and the dust collecting cover plate in the processing technology can be ensured, which helps to improve the production efficiency and reduce the production cost.

[0022] Secondly, by using the same material, the base and the dust collecting cover plate can have the same physical properties, such as strength, rigidity and impact resistance. In this way, it helps to improve the overall structural stability and durability of the cleaning device, and ensures the stable operation of the cleaning device.

[0023] In addition, the same material has the same thermal expansion coefficient, which can avoid the inconsistent size change between the base and the dust collecting cover plate due to temperature change, thereby reducing the assembly problems caused by thermal expansion or contraction, and improving the reliability and service life of the cleaning device.

[0024] In the cleaning device, optionally, the dust box has a receiving cavity, and a dust inlet, an air inlet and a dust outlet communicating with the receiving cavity, the dust inlet is used for the dirt to enter the dust box for storage;

[0025] The input end of the air suction duct is connected to the air inlet, and the input end of the dust collecting duct is connected to the dust outlet.

[0026] Through the above arrangement, the dirt can enter the dust box through the dust inlet, the airflow in the dust box can move out through the air inlet, and the dirt in the dust box can move out through the dust outlet, thereby realizing the collection and transfer of the dirt in the dust box.

[0027] In the cleaning device, optionally, in the height direction of the cleaning device, the air inlet is higher than the dust outlet and the dust inlet;

[0028] And / or,

[0029] The air inlet and the dust outlet are arranged on the same side of the dust box, and the dust inlet and the dust outlet are arranged on different sides of the dust box.

[0030] Through the above arrangement, the higher position of the air inlet can make the airflow flow smoothly downward in the dust box, which can reduce the resistance and energy loss of the airflow in the transmission process and improve the transmission efficiency of the airflow.

[0031] In the cleaning device, optionally, further comprising an air suction fan, the air suction fan is located between the air suction duct and the air outlet duct;

[0032] The length of the air outlet duct is greater than the length of the air suction duct.

[0059] The technical solutions in the embodiments of the present application will be described clearly and completely in the description of the embodiments of the present application, obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0060] In the first aspect, the embodiments of the present application provide a cleaning system (not shown in the figure), which comprises a base station (not shown in the figure) and a cleaning device 10.

[0061] It can be understood that after the cleaning device 10 completes the cleaning of the cleaning surface, it can be placed on the base station for positioning, charging or self-cleaning. The base station is provided with a placing position of the cleaning device 10, so that the positioning of the cleaning device 10 can be realized. The base station is provided with a charging interface, so that the charging of the cleaning device 10 can be realized.

[0062] It should be noted that the base station generally needs to be placed on the ground to support the operation of the cleaning device 10.

[0063] It can be understood that the cleaning device 10 can be different types of devices, for example, the cleaning device 10 can be a sweeping robot, a sweeping and mopping integrated robot, or a dust collector, etc. Different types of cleaning devices 10 have corresponding base stations.

[0064] The following will be described taking the cleaning device 10 as a sweeping robot as an example.

[0065] Referring to Figure 1In a second aspect, the embodiments of the present application further provide a cleaning device 10, comprising a housing 100 and a dust box 200, the housing 100 comprising a base 110, and the dust box 200 being mounted on the base 110, and the dust box 200 being used for collecting dirt.

[0066] With reference to Figure 2 In some embodiments, the base 110 has a mounting cavity 111 for placing the dust box 200, and the dust box 200 can be located in the mounting cavity 111. It can be understood that the base 110 also has a dirt suction port communicating with the mounting cavity 111, and the dirt suction port is used for sucking dirt so that the dirt enters the dust box 200 to complete the cleaning work. That is, the dirt enters the dust box 200 located in the mounting cavity 111 through the dirt suction port.

[0067] With reference to Figure 2 Specifically, the housing 100 further comprises an air suction duct 120, an air outlet duct 130 and a dust collection duct 140, the air suction duct 120 and the dust collection duct 140 both communicating with the dust box 200, the air suction duct 120 communicating with the air outlet duct 130, and the air outlet duct 130 and the dust collection duct 140 both being used for communicating with the external environment.

[0068] It can be understood that the air suction duct 120 circulates a suction airflow, and under the action of the suction airflow, a negative pressure is formed inside the dust box 200, so that the dirt can enter the dust box 200 through the dirt suction port, and then the cleaning work is completed. With reference to Figure 1 and Figure 3 The a path is the path of the suction airflow, the b path is the path of the dirt entering the base station from the dust box 200, and the c path is the path of the dirt entering the dust box 200 from the surface to be cleaned. It can be understood that the a path and the c path occur at the same time, that is, the c path is realized by the airflow generated by the a path to suck the dirt. The b path occurs independently.

[0069] The base station has a collection channel corresponding to the dust collection duct 140; when the cleaning device 10 is docked with the base station, the input end of the collection channel communicates with the output end of the dust collection duct 140. Correspondingly, the base station is also provided with a dust bag communicating with the collection channel, and the base station can collect the dirt collected by the cleaning device 10 during cleaning into the dust bag through the collection channel.

[0070] It can be understood that the dust bag usually has a large capacity and can collect the dirt obtained by the cleaning device 10 multiple times. When the dirt collected by the dust bag reaches the maximum capacity, the cleaning system can prompt the user to clean the dust bag. The way of prompting the user includes but is not limited to a prompt sound, a prompt light, etc.

[0071] It should be noted that in order to complete the collection of dirt, the base station is further provided with a collection fan, the collection fan is communicated with the collection channel (in essence, a dust collection air duct in the base station), and the collection fan can provide suction. When the base station is docked with the cleaning device 10, the input end of the collection channel is communicated with the output end of the dust collection air duct 140, and the output end of the collection channel is communicated with the dust bag. The collection fan works and provides suction to suck the dirt, so that the dirt can be separated from the dust collection air duct 140 of the cleaning device 10 and enter the collection channel, and then enter the dust bag through the collection channel to complete the collection of dirt.

[0072] It should be noted that in order to avoid the dirt in the dust box 200 being discharged from the dust box 200 along the air suction duct 120, the dust box 200 can be further provided with a filtering structure, which can filter the dirt to stay in the dust box 200 and not affect the air suction fan 300.

[0073] Referring to Figure 2 In some embodiments, the cleaning device 10 further comprises an air suction fan 300, which is located between the air suction duct 120 and the air outlet duct 130, that is, the air suction fan 300 is respectively communicated with the left side of the air suction duct 120 and the right side of the air outlet duct 130. The air suction fan 300 can provide the aforementioned suction airflow to generate negative pressure in the dust box 200, so as to suck the dirt through the dirt suction port, that is Figures 2-3 The c path in FIG. 13, and the air is circulated to the outside of the cleaning device 10 through the air outlet duct 130, that is Figures 1-3 The a path in FIG. 13.

[0074] According to the foregoing, the dust collection air duct 140 is used to transfer the dirt of the cleaning device 10 to the base station. That is, the input end of the dust collection air duct 140 is communicated with the dust box 200. When the cleaning device 10 is docked with the base station, the collection fan works and provides suction to suck the dirt, that is Figures 2-3 The c path in FIG. 13, so that the dirt can enter the dust collection air duct 140 from the dust box 200, that is Figures 1-3 The b path in FIG. 13, and then enter the collection channel through the dust collection air duct 140, and enter the dust bag through the collection channel to complete the collection of dirt.

[0075] It can be understood that the air suction fan 300 can be installed on the base 110 through the mounting frame 400. The two ends of the mounting frame 400 can be respectively communicated with the air inlet channel and the air outlet channel.

[0076] In some embodiments, the air outlet duct 130 and the dust collection air duct 140 are located on the same side of the dust box 200. The aforementioned same side includes but is not limited to the left side, the right side, the front side or the rear side of the dust box 200. In the embodiments of the present application, referring to Figures 1-3 , the air outlet duct 130 and the dust collection air duct 140 are located on the left side of the dust box 200.

[0077] It can be understood that the air outlet air duct 130 and the dust collection air duct 140 are both used for air exhaust and both used for communication with the external environment. The layout of the two channels described above in the prior art is arranged on the left and right sides of the cleaning device 10, which can cause problems such as too long pipe and too many bends. By arranging the air outlet air duct 130 and the dust collection air duct 140 on the same side of the cleaning device 10, the layout of the air flow channel and the air flow transmission path inside the cleaning device 10 can be optimized, the air path structure is relatively compact, which is conducive to reducing the size of the cleaning device 10 and meeting the user's demand for product miniaturization.

[0078] With reference to Figure 2 As an optional embodiment, the output end of the air outlet air duct 130 is arranged adjacent to the output end of the dust collection air duct 140.

[0079] With reference to the accompanying Figure 2 It can be seen that the output end of the air outlet air duct 130 and the output end of the dust collection air duct 140 are both located on the left side of the cleaning device 10, and the distance between the output end of the air outlet air duct 130 and the output end of the dust collection air duct 140 is small, forming an adjacent arrangement.

[0080] With reference to the accompanying drawings, it can be seen that the output end of the air outlet air duct 130 and the output end of the dust collection air duct 140 are both located on the left side of the dust box 200.

[0081] Through the above arrangement, the cleaning device 10 can be arranged with other structures in a limited space, thereby improving the space utilization of the cleaning device 10 and facilitating the miniaturization design of the cleaning device 10 to meet the user's demand.

[0082] With reference to Figure 2 As an optional embodiment, the input end of the air outlet air duct 130 is arranged spaced apart from the input end of the dust collection air duct 140, and both are located on the same side of the dust box 200.

[0083] With reference to the accompanying drawings, it can be seen that the input end of the air outlet air duct 130 and the input end of the dust collection air duct 140 are both located on the left side of the dust box 200, and the distance between the input end of the air outlet air duct 130 and the input end of the dust collection air duct 140 is large, forming a spaced apart arrangement. In addition, according to the drawings, it can be seen that the output end of the air outlet air duct 130 and the output end of the dust collection air duct 140 are both located on the left side of the dust box 200.

[0084] It can be understood that the above-mentioned spacing can be used to place the air suction fan 300, which can improve the space utilization and facilitate the miniaturization of the cleaning device 10 to meet the user's demand.

[0085] With reference to Figure 2As an optional embodiment, the length of the air outlet duct 130 is greater than the length of the air inlet duct 120. That is, the air outlet duct 130 occupies a longer path, and the air inlet duct 120 is relatively shorter.

[0086] It can be understood that the longer air outlet duct 130 can reduce the air flow speed and reduce the noise generated by the air flow when being discharged, so as to reduce noise pollution and improve the use comfort of the cleaning device 10.

[0087] It should be noted that in the embodiment of the present application, the distance between the air inlet fan 300 and the dust box 200 is short, that is, the air inlet end of the air inlet fan 300 directly communicates with the dust box 200. The above-mentioned short distance can form the air inlet duct 120 as described above, so that the length of the air inlet duct 120 is short,

[0088] It should be noted that in the attached Figure 1 , the attached Figure 2 and the attached Figure 3 , the structure of other areas on the base 110 is not shown in addition to the dust box 200, the dust collection cover plate 500, the air inlet fan 300 and the mounting frame 400 shown.

[0089] Referring to the attached Figure 4 , Figure 5 As an optional embodiment, the shell 100 further comprises a dust collection cover plate 500, and the dust collection cover plate 500 and part of the base 110 form a dust collection duct 140. Specifically, the dust collection cover plate 500 can be located above the base 110 in the height direction H, and the dust collection duct 140 is formed between the dust collection cover plate 500 and the base 110.

[0090] It should be noted that the height direction H referred to in the embodiment of the present application is only used to illustrate the relative position relationship between different structures in the attached Figure 4 - the attached Figure 6 , and is not equivalent to the actual application. For example, in the actual application, the dust collection cover plate 500 is located below the base 110 in the direction of gravity. The height direction H will not be described below.

[0091] Specifically, the base 110 can include a bottom plate 113, a first plate 114 and a second plate 115, the first plate 114 and the second plate 115 are arranged on the bottom plate 113, and the first plate 114 and the second plate 115 can be arranged in a spaced manner. As shown in the attached Figure 4 , the attached Figure 5 It can be seen that the first plate 114 and the second plate 115 are arranged vertically with the bottom plate 113. The first plate 114, the second plate 115 and part of the bottom plate 113 between the first plate 114 and the second plate 115 form a lower half of the dust collection duct 140.

[0092] It can be understood that, in order to improve the structural strength of the dust collection air duct 140, the first plate 114, the second plate 115 and the bottom plate 113 can be an integral piece, that is, the bottom plate 113, the first plate 114 and the second plate 115 can be integrally formed, such as by casting.

[0093] The dust collection cover plate 500 includes a cover plate body 510 and two side plates 520 connected to both sides of the cover plate body 510, and the cover plate body 510 and the two side plates 520 can be circumferentially formed to form the upper half of the dust collection air duct 140.

[0094] It can be understood that, when the two side plates 520 of the dust collection cover plate 500 are connected to the first plate 114 and the second plate 115 respectively, the dust collection cover plate 500 and the base 110 can be circumferentially formed to form the dust collection air duct 140.

[0095] Through the above arrangement, the cleaning device 10 only needs one dust collection cover plate 500 to form the dust collection air duct 140, compared with the prior art scheme of forming the air duct by two cover plates, the number of structures required for the dust collection air duct 140 can be reduced, and the cost can be reduced. In addition, in the prior art, two cover plates need to be connected to form an air duct first, and then the connected structure needs to be installed on the base 110, which needs multiple positioning and multiple connection. The dust collection air duct 140 provided in the embodiment of the application only needs one positioning and one connection to form the dust collection air duct 140, which can reduce the assembly process and thus improve the assembly efficiency.

[0096] As an optional embodiment, the base 110 is made of the same material as the dust collection cover plate 500.

[0097] Specifically, the base 110 can be made of plastic, for example, the base 110 can be made of one or more of ABS (Acrylonitrile-butadiene-styrene), PC (Polycarbonate), PP (Polypropylene), PVC (Polyvinyl Chloride), PS (Polystyrene) and PA (Polyamide).

[0098] The dust collection cover plate 500 is made of the same material as the base 110, which will not be repeated here. The base 110 and the dust collection cover plate 500 are not limited to the above examples in terms of specific materials.

[0099] Hereinafter, the base 110 and the dust collection cover plate 500 are taken as examples to be made of ABS material.

[0100] By using the same material for preparation, the base 110 and the dust collecting cover plate 500 can be ensured to be consistent in the processing technology, which helps to improve the production efficiency and thus reduce the production cost.

[0101] Secondly, by using the same material, the base 110 and the dust collecting cover plate 500 can have the same physical properties such as strength, rigidity and impact resistance. In this way, it helps to improve the overall structural stability and durability of the cleaning device 10, and ensures that the cleaning device 10 can operate stably.

[0102] In addition, the same material has the same coefficient of thermal expansion, which can avoid the inconsistent size change between the base 110 and the dust collecting cover plate 500 due to temperature change, thereby reducing the assembly problems caused by thermal expansion or contraction, and improving the reliability and service life of the cleaning device 10.

[0103] Referring to Figure 6 , as an optional embodiment, the dust box 200 has a containing cavity 201. The containing cavity 201 is used to store the dirt collected during the cleaning process. The dust box 200 also has a dust inlet 202, an air inlet 203 and a dust outlet 204 communicating with the containing cavity 201, and the dust inlet 202 is used for the dirt to enter the dust box 200 for storage.

[0104] It can be understood that the dust inlet 202 enables the dirt to smoothly enter the containing cavity 201 of the dust box 200, which can improve the collection efficiency of the dirt. The input end of the air suction duct is connected to the air inlet 203, and the input end of the dust collecting duct 140 is connected to the dust outlet 204, that is, the air suction duct can be in communication with the dust box 200 through the air inlet 203, and the dust collecting duct 140 can be in communication with the dust box 200 through the dust outlet 204.

[0105] It should be noted that the position and shape of the dust inlet 202 can be selected according to actual needs to adapt to different cleaning scenes and types of dirt, further improving the adaptability and cleaning effect of the cleaning device 10, and the embodiments of the present application do not limit the same. The position and shape of the dust outlet 204 and the air inlet 203 can refer to the description of the dust inlet 202, which will not be repeated here.

[0106] Through the above arrangement, the dirt can enter the dust box 200 through the dust inlet 202, the airflow in the dust box 200 can move out through the air inlet 203, and the dirt in the dust box 200 can move out through the dust outlet 204, thereby realizing the collection and transfer of the dirt in the dust box 200.

[0107] Referring to Figure 6 , as an optional embodiment, the dust inlet 202 and the dust outlet 204 are arranged on different surfaces of the dust box 200, so that the dirt can smoothly enter the dust box 200 and be effectively collected.

[0108] In the embodiments of the present application, with reference to Figure 2 , Figure 3 and Figure 6 , the base 110 further has a dirty inlet 112 for the dirty to enter the installation cavity 111 so as to complete the cleaning operation in the dust box 200. It can be understood that the dust inlet 202 corresponds to the dirty inlet 112, that is, the dirty can enter the dust box 200 through the dirty inlet 112 and the dust inlet 202.

[0109] With reference to Figure 6 , further, the air inlet 203 and the dust outlet 204 are arranged on the same side of the dust box 200, that is, on the left end face of the dust box 200, so that the flow path of the airflow in the dust box 200 can be simplified, the resistance and energy loss of the airflow in the transmission process can be reduced, and the transmission efficiency of the airflow can be improved.

[0110] With reference to Figure 6 , as an optional embodiment, in the height direction H of the cleaning device 10, the air inlet 203 is higher than the dust outlet 204 and the dust inlet 202;

[0111] It can be understood that under the action of the suction fan 300, a negative pressure can be formed in the dust box 200, and under the action of the negative pressure, the airflow can drive the dirty to enter the dust box 200 through the dirty inlet 112 and the dust inlet 202.

[0112] It should be noted that according to the foregoing, the dust box 200 is provided with the filter 210, in some embodiments, the filter 210 can directly cover the input end of the suction air duct 120, that is, directly cover the air inlet 203. In this way, the filter 200 can block the dirty and only make the air flow out through the air inlet 203, so that the dirty is kept in the dust box 200;

[0113] In some other embodiments, the filter 210 is large in size and can cover part of the containing cavity 201 of the dust box 200, that is, between the air inlet 203 and the dust inlet 202 in the height direction H, so that the dirty is kept in the dust box 200.

[0114] As an optional embodiment, the positions of the dust inlet 202 and the dust outlet 204 are respectively provided with a first sealing plate 220 and a second sealing plate 230, and the first sealing plate 220 and the second sealing plate 230 are both rotationally arranged in the dust box 200.

[0115] In the first case, that is, when the cleaning device 10 is docked with the base station, the collection channel can release the suction airflow to the dust collection air duct 140, and under the action of the negative pressure, the second sealing plate 230 can be rotated to open the dust outlet 204, so that the dirty in the dust box 200 can enter the dust bag through the dust collection air duct 140 and the collection channel, that is,Figures 1-3 The b path in the text.

[0116] In the second scenario, when the cleaning equipment 10 is in the process of cleaning, the suction fan 300 can provide suction airflow, resulting in lower air pressure in the suction duct 120. Since the suction duct 120 remains connected to the air inlet 203, the dust box 200 is under negative pressure. Under this negative pressure, the first sealing plate 220 can rotate and open the dust inlet 202, allowing dirt to be sucked in. The dirt then enters the dust box 200 through the suction port 112 and the dust inlet 202. Figures 2-3 In path c, the airflow released by the suction fan 300 flows from the outlet duct 130 to the outside of the cleaning equipment 10. Figures 1-2 The cleaning operation of the cleaning equipment 10 is completed by following path a in the middle.

[0117] It should be noted that the first and second scenarios mentioned above are handled separately.
