Description

Technical Field

[0001] The embodiments of the utility model relate to the technical field of cleaning equipment, and in particular, to a dust hood, a dust box assembly having the dust hood, a cleaning equipment having the dust box assembly, and a cleaning system having the cleaning equipment. Background Art

[0002] With the development of science and technology, the types of cleaning equipment are becoming more and more complete, including floor scrubbers, sweeping robots, window cleaning robots, etc., to replace users to complete the cleaning work of floors, doors and windows. Among them, the representative self-propelled cleaning robots are becoming more and more popular among young people.

[0003] The self-propelled cleaning robot is provided with a fan, an air duct assembly, a roller brush assembly and a dust box. The air duct assembly is connected between the vent of the roller brush assembly and the air inlet of the dust box. The roller brush assembly includes a rotatable roller brush, which contacts the surface to be cleaned and rotates to lift up dust and garbage on the surface to be cleaned. In this process, the suction negative pressure generated by the fan sucks the dust and garbage into the dust box through the air duct assembly, thereby collecting the garbage on the surface to be cleaned.

[0004] Self-mobile cleaning robots are usually also equipped with a cleaning base station. After the self-mobile cleaning robot has worked for a period of time or completed cleaning the predetermined area, it will automatically return to the cleaning base station to charge and clean the dust and garbage in the dust box. This process is called dust collection. The cleaning base station is usually equipped with an automatic dust collection component, which can transfer the dust and garbage temporarily stored in the dust box of the self-mobile cleaning robot to the cleaning base station for storage. However, the dust boxes currently on the market will accumulate dirt after long-term use. This dirt cannot be automatically removed by the cleaning base station, and the dust box needs to be removed for manual maintenance and cleaning, which reduces the user experience. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, an embodiment of the utility model provides a dust box assembly. The dust box assembly includes: a dust box seat, the dust box seat includes a dust removal channel; and a dust collecting hood, the dust collecting hood is made of a rigid material, a dust collecting cavity is formed in the dust collecting hood, the dust collecting hood is detachably mounted on the dust box seat, the dust collecting hood has a dust collecting air inlet, a dust collecting air outlet and a dust removal port, and the dust collecting air inlet, the dust collecting air outlet and the dust removal port are all connected to the dust collecting cavity. When the dust collecting hood is assembled to the dust box seat, the dust removal port is connected to the entrance of the dust removal channel.

[0006] Another aspect of the utility model also provides a cleaning device, including a fan; and the above-mentioned dust box assembly, the fan is connected to the dust collection outlet, and is used to form a negative pressure in the dust collection chamber; wherein the cleaning device includes at least one of the following: a self-moving cleaning robot, a handheld vacuum cleaner.

[0007] Another aspect of the utility model also provides a cleaning system, including: a cleaning base station, in which a dust storage component and a dust removal fan are arranged, and the air inlet of the dust removal fan is connected to the dust storage component to form a negative pressure in the dust storage component; and the above-mentioned cleaning equipment, which can be selectively docked with the cleaning base station, and when the cleaning equipment is docked with the cleaning base station, the inlet of the dust storage component is fluidly connected with the outlet of the dust removal channel.

[0008] In the above technical solution, since the dust hood is a component that can be removed from the dust box seat and replaced, even after long-term use, when there is a lot of dirt accumulated in the dust hood, the user can choose to directly discard the dust hood and replace it with a new one, thereby reducing the difficulty of maintaining the dust box assembly for the user. Furthermore, the wall thickness of the dust hood can be relatively thin, and the dust box seat cooperates with the dust hood to provide support for the dust hood, thereby ensuring its structural strength. Optionally, for example, a handheld part, a part that limits and aligns with the main body of the cleaning robot, a dust box filter that filters the airflow output from the dust outlet (as will be mentioned below), and a dust removal channel that is not so easy to be contaminated by garbage can be set on the dust box seat, which can simplify the structure of the dust hood, thereby further reducing costs. In some embodiments, the dust hood can be made by processes such as blow molding and injection molding, so as to be produced in large quantities at low cost. Since it is a consumable material itself, it only needs to ensure its basic service life, so recycled plastic can be used as a raw material, thereby taking into account both environmental protection and use costs.

[0009] A series of simplified concepts are introduced in the utility model content, which will be further described in detail in the detailed implementation section. The utility model content section does not mean to attempt to define the key features and essential technical features of the technical solution claimed for protection, nor does it mean to attempt to determine the scope of protection of the technical solution claimed for protection.

DETAILED DESCRIPTION

[0032] In the following description, a large number of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0033] According to an embodiment of the present invention, a dust box assembly is provided, which can be applied to any suitable cleaning device, such as a vacuum cleaner, a self-propelled cleaning robot (such as a sweeping robot), a window cleaning robot, etc. These cleaning devices can be equipped with a cleaning base station. Fig.14A and Fig. 14B As shown, Fig.14A The cleaning device 100 is a sweeping robot. Fig. 14B The cleaning device 100 in the figure is a vacuum cleaner. The cleaning device 100 has a dust box assembly 10. When the dust box assembly 10 is installed in place on the cleaning device 100, the inner cavity of the dust box assembly 10 will dock with the cleaning device docking interface 1011 of the cleaning device 100, but when the cleaning device 100 performs a cleaning task, the inner cavity of the dust box assembly 10 is not fluidly connected with the cleaning device docking interface 1011. After the cleaning device 100 works for a predetermined time or completes the cleaning of a predetermined area, it can return to the cleaning base station 200, and the cleaning device docking interface 1011 of the cleaning device 100 docks with the base station docking interface 2031 of the cleaning base station 200. Under the action of the dust removal fan 202 of the cleaning base station 200, the inner cavity of the dust box assembly 10 is fluidly connected with the cleaning device docking interface 1011, and the garbage collected in the inner cavity of the dust box assembly 10 passes through the suction channel 203 of the cleaning base station 200 and is transferred to the dust storage assembly 201 of the cleaning base station 200. The dust storage assembly 201 may include a dust storage bag 2011, which has a large volume. Some cleaning base stations also have a dust and garbage compression function, so the user can process the dust and garbage transferred from the cleaning device 100 after the cleaning base station 200 receives the dust and garbage multiple times, such as directly discarding the dust storage bag 2011, thereby reducing the user's maintenance frequency.

[0034] However, the inventors have found through creative work that although the cleaning device 100 currently on the market can transfer the garbage in the dust box of the cleaning device 100 to the dust storage component 201 of the cleaning base station 200 for storage after docking with the cleaning base station 200. However, in the process of the cleaning device 100 cleaning the surface to be cleaned, the dust and garbage will hit and adhere to the inner wall of the dust box when being sucked into the dust box of the cleaning device 100. When the air humidity is high or garbage with high humidity enters, the inner wall of the dust box will become wet, and the dust and other fine garbage attached to its surface will adhere firmly to the dirt after drying and become difficult to clean. Over time, the dirt accumulates more and more. These dirt cannot be automatically removed by the cleaning base station 200, and the dust box needs to be removed for manual maintenance and cleaning, which reduces the user experience.

[0035] Therefore, in order to solve the above technical problems, the present application provides a dust box assembly, which can reduce the maintenance difficulty of the dust box assembly. The dust box assembly, dust storage cover, cleaning device and cleaning system provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0036] Figure 1A An exploded view of a cleaning device 100 according to an embodiment of the present application is shown. Figure 1B FIG. 1 is a cross-sectional view of a cleaning device 100 according to an embodiment of the present application. Figure 1A-1B As shown, the cleaning device 100 may include a dust box assembly 10, a device body 20 and a cover body 30. The device body 20 may have a storage bin 21. The storage bin 21 has a dust inlet 22. The dust box assembly 10 may be detachably mounted in the storage bin 21. After the dust box assembly 10 is mounted in the storage bin 21, the dust collection air inlet of the dust box assembly 10 is connected to the dust inlet 22 of the storage bin 21. In addition, the device body 20 may also have a communication port 231, and a cleaning member may be provided near the communication port 231. The communication port 231 is connected to the dust inlet 22. The dust inlet 22 is used to communicate with the dust box assembly 10. The cleaning member may include one or more of a roller brush 40 and a side brush. When the cleaning member includes the roller brush 40, a mounting bin 23 with an opening facing downward may be provided at the bottom of the device body 20, and the roller brush 40 may be rotatably mounted in the mounting bin 23 around a horizontal rotation axis. Typically, a brush is provided on the outer peripheral side of the roller brush 40. The tip of the brush can extend out of the opening of the installation bin 23 to clean the garbage on the surface to be cleaned. Optionally, a rubber brush is also provided on the outer peripheral side of the roller brush 40, and the rubber brush and the brush are spirally arranged along the peripheral side of the roller brush 40. The spirally arranged rubber brush and brush have the function of guiding the hair to move toward the dust collection port 231. The connecting port 231 can be provided on the side wall of the installation bin 23 to connect the receiving bin 21 and the installation bin 23. In this way, an airflow channel ( Figure 1B The thick dashed line in the middle is the airflow path. A negative pressure device such as a fan can be connected to the end of the airflow channel. When the negative pressure device is working, negative pressure can be formed in the installation bin 23, so that the dust and garbage swept by the roller brush 40 flow along the airflow channel together with the air. When the dust and garbage pass through the dust box assembly 10, they are filtered by the filter structure of the dust box assembly 10 and collected in the dust box assembly 10. The clean air can be discharged into the environment after passing through the negative pressure device.

[0037] The side brush is usually arranged on the front side of the device body 20 and located on the outside of the installation bin 23, and is used to clean the dust and garbage toward the opening of the installation bin 23. In the above embodiment, the dust and garbage on the surface to be cleaned are collected into the dust box assembly 10 under the action of the airflow. Therefore, in addition to the dust collection air inlet, the dust box assembly 10 also needs to be provided with a dust collection air outlet for discharging clean air. The dust collection air outlet can be connected to the negative pressure device. The cover body 30 is detachably buckled on the device body 20, or the cover body 30 is hinged to the device body 20, so that the cover body 30 can be flipped to the device body 20. The cover body 30 is removed from the device body 20 or flipped relative to the device body 20 to expose the storage bin 21, so that the dust box assembly 10 can be maintained and disassembled.

[0038] Figures 2A to 4 A dust box assembly 10 according to an exemplary embodiment of the present application is shown. Fig.11A A schematic structural diagram of a cleaning system provided for an exemplary embodiment of the present application. Fig. 11B This is a schematic diagram of the structure of a cleaning system provided by another exemplary embodiment of the present application. Figures 2A to 4 , and combined with Fig.11A or Fig. 11B The dust box assembly 10 may include a dust box seat 110 and a dust hood 120. The dust box seat 110 and the dust hood 120 may be made of any suitable rigid material. Exemplarily, both the dust box seat 110 and the dust hood 120 may be made of plastic, but may be made of the same plastic or different plastics. As will be mentioned later, the dust hood 120 is a consumable and will be replaced regularly, while the dust box seat 110 is a basic frame to ensure the overall mechanical strength of the dust box assembly 10. Therefore, the dust hood 120 may be made of a thinner material or a slightly inferior material than the dust box seat 110 to reduce costs.

[0039] The dust box seat 110 may include a dust removal channel 112. When the dust box assembly 10 is mounted on the cleaning device 100, the outlet 112b of the dust removal channel 112 docks with the cleaning device docking port 1011. After the cleaning device 100 docks with the cleaning base station 200, the outlet 112b of the dust removal channel 112 may be fluidly connected to the dust storage assembly 201 (for example, including a dust storage bag 2011 and a dust storage bag storage bin 2012) on the cleaning base station 200.

[0040] The dust collecting hood 120 is detachably mounted on the dust box seat 110. A dust collecting chamber 121 is formed in the dust collecting hood 120. The dust collecting hood 120 has a dust collecting air inlet 124, a dust collecting air outlet 125 and a dust removal port 126, and the dust collecting air inlet 124, the dust collecting air outlet 125 and the dust removal port 126 are all connected to the dust collecting chamber 121. The dust collecting chamber 121 is used to collect garbage during the operation of the cleaning device 100. In the embodiment of the present application, this process can be referred to as "dust collection". During the dust collection process, the airflow carries the garbage from the dust collecting air inlet 124 into the dust collecting chamber 121, the garbage is retained in the dust collecting chamber 121, and the air leaves from the dust collecting air outlet 125. In the assembled state where the dust collecting hood 120 is mounted to the dust box seat 110, the dust removal port 126 can be connected to the inlet 112a of the dust removal channel 112. Exemplarily, the dust removal port 126 can be connected to the inlet 112a of the dust removal channel 112 by docking. In other embodiments, the dust removal port 126 can be directly or indirectly connected to the inlet 112a of the dust removal channel 112 by other means. Thus, when the cleaning device 100 is docked with the cleaning base station 200, the airflow can enter the dust collection chamber 121 from the dust collection air inlet 124, and pass through the dust collection channel 112 and the dust storage assembly 201 on the cleaning base station 200 in turn, so that the garbage in the dust collection chamber 121 is transferred to the dust storage assembly 201 of the cleaning base station 200. In the embodiment of the present application, this process can be referred to as "dust removal". After a period of use, when the interior of the dust hood 120 is stuck with dirt that is not easy to clean or is full of garbage, it can be discarded and a new dust hood 120 can be replaced with the dust box seat 110.

[0041] Generally, the dust collecting chamber 121 has a substantially long shape. For the convenience of subsequent description, the longitudinal direction X1-X2, the transverse direction Y1-Y2 and the vertical direction Z1-Z2 are defined, wherein the dust collecting chamber 121 has a larger dimension along the longitudinal direction X1-X2 relative to other directions, so this direction can be considered as the length direction of the dust collecting chamber 121. Figure 1A-1BFor the cleaning device 100 (self-propelled cleaning robot) shown, the longitudinal direction X1-X2 and the transverse direction Y1-Y2 are located in the horizontal plane when the self-propelled cleaning robot is in normal use; and the transverse direction Y1-Y2 is perpendicular to the longitudinal direction X1-X2 on the horizontal plane; the vertical direction Z1-Z2 is a vertical direction, wherein the vertical upward direction is the Z1 direction, and the vertical downward direction is the Z2 direction. For other types of cleaning equipment, such as a window cleaning machine or a swimming pool robot capable of climbing a wall, the surface to be cleaned may include a wall. The plane determined by the longitudinal direction X1-X2 and the transverse direction Y1-Y2 will be parallel to the wall, and the vertical direction Z1-Z2 will be perpendicular to the wall. In short, the plane determined by the longitudinal direction X1-X2 and the transverse direction Y1-Y2 is parallel to the surface to be cleaned, while the vertical direction Z1-Z2 is perpendicular to the surface to be cleaned. Regardless of the placement state of the cleaning device 100 using the dust box assembly 10 in the working state, when it returns to the cleaning base station 200, the plane defined by the longitudinal direction X1-X2 and the transverse direction Y1-Y2 is parallel to the ground. The following description will be described with reference to the placement state returned to the cleaning base station 200.

[0042] exist Figure 4In the illustrated embodiment, the dust collecting chamber 121 has a dust collecting end 122 and a dust removing end 123 which are arranged opposite to each other along the longitudinal direction X1-X2. The dust collecting air inlet 124 and the dust removing port 126 are respectively located on the dust collecting end 122 and the dust removing end 123. In the illustrated embodiment, the dust collecting air inlet 124 is located at the side portion of the dust collecting end 122, and the dust removing port 126 is located at the end portion of the dust removing end 123. The dust collecting air outlet 125 is closer to the dust removing port 126 and is arranged on the side portion of the dust collecting cover 120. Usually, the dust collecting air inlet 124 and the dust collecting air outlet 125 are located on the same side to adapt to the layout on the cleaning device 100. Moreover, the dust collecting air inlet 124 and the dust collecting air outlet 125 are arranged in sequence along the longitudinal direction X1-X2, so that the dust collecting chamber 121 can store more garbage. Taking all factors into consideration, the dust collecting chamber 121 is arranged to have a longitudinally long structure. Of course, optionally, if the layout in the cleaning device 100 allows, the dust collection air inlet 124 can also be set on the end portion of the dust collection end 122. The "side portion" described here refers to the portion of the dust hood 120 that surrounds the dust collection chamber 121 along the lateral direction Y1-Y2 and the vertical direction Z1-Z2; and the end portion refers to the portion of the dust hood 120 that is opposite to the longitudinal direction X1-X2. Exemplarily, the inner surface of the dust collection chamber 121 does not have a relatively clear or sharp corner or protrusion. If the inner surface of the dust collection chamber 121 needs to have a corner due to the shape or processing technology of the dust box seat 110 and / or the mounting bin 23, the corner is preferably a rounded corner. In this way, in the process of transferring dust and garbage from the dust collection chamber 121 of the cleaning device 100 to the cleaning base station 200, it is convenient for the airflow to take away all the garbage in the dust collection chamber 121, and it is not easy to accumulate dust in the corner. Moreover, the design with no corners or rounded corners can further reduce the difficulty of cleaning when the user cleans the dust box assembly 10, and no sanitary dead corners will be generated.

[0043] like Figure 2A and Figure 2B As shown, the dust box assembly 10 may have a flat box-shaped structure. Figure 2A When the dust collecting air inlet 124 is horizontally mounted on the main body 20 of the cleaning device 100, the opening of the dust collecting air inlet 124 faces the side, and a hand-held portion 111 for lifting the dust box assembly 10 is provided on the top. Figure 1A ) The hand-held portion 111 may be disposed on the dust box seat 110. By disposing components such as the hand-held portion 111 on the dust box seat 110, it is possible to avoid affecting the shape of the dust collecting chamber 121 in the dust collecting hood 120, such as causing the dust collecting chamber 121 to have obvious corners and / or protrusions, etc., and the structure of the dust collecting hood 120 may be simplified, thereby reducing the difficulty and cost of processing the dust collecting hood 120.

[0044] When the cleaning device 100 is working, with the help of cleaning parts (such as roller brushes and side brushes), dust and garbage are collected into the dust collection chamber 121 of the dust collection cover 120 through the dust collection air inlet 124. When the cleaning device 100 returns to the cleaning base station 200, the cleaning base station 200 can transfer the dust and garbage temporarily stored in the dust collection chamber 121 to the cleaning base station 200 by blowing air into the dust collection chamber 121 and / or sucking air from the dust collection chamber 121. In some embodiments, the cleaning base station 200 may include a dust storage assembly 201 and a dust removal fan 202. After the cleaning device 100 is docked to the cleaning base station 200, the air inlet of the dust removal fan 202 can be connected to the dust storage assembly 201 on the cleaning base station 200 to form a negative pressure in the dust storage assembly 201. The dust storage assembly 201 is also in communication with the dust removal channel 112 of the dust box assembly 10, and the dust collection air inlet 124 of the dust box assembly 10 is still in communication with the atmosphere. When the dust removal fan 202 is started, negative pressure is formed in the dust storage assembly 201, and air is replenished into the dust collection chamber 121 from the dust collection air inlet 124, which can help bring dust and garbage into the dust storage assembly 201. At the same time, since the power of the dust removal fan 202 is usually large, in this process, under the action of the dust removal airflow, the hair garbage and the like remaining on the roller brush 40 can be sucked into the dust collection chamber 121, and then further brought into the dust storage assembly 201 of the cleaning base station 200. In some other embodiments, the cleaning base station 200 may include a blower (not shown in the figure) and a dust storage assembly 201, and the air outlet of the blower can be connected to the dust collection air inlet 124 of the dust box assembly 10, and the cleaning device 100 docks with the cleaning base station 200, and the blower blows air into the dust box assembly 10, and the air brings the dust and garbage in the dust collection chamber 121 into the dust storage assembly 201 of the cleaning base station 200. Of course, the cleaning base station 200 can also be provided with a blowing device, a dust removal fan and a dust storage component at the same time.

[0045] As the cleaning device 100 is cleaning the surface to be cleaned, dust and garbage will stay in the dust collecting chamber 121 for a long time. Only when the cleaning device 100 returns to the cleaning base station 200, the dust and garbage will leave the dust collecting chamber 121 from the dust removal channel 112. Analyzed from another perspective, since the garbage and dust are in motion in the dust removal channel 112, and the time for the transfer of garbage and dust from the dust removal channel 112 to the cleaning base station 200 is relatively short. In contrast, most of the dust and garbage in the dust collecting chamber 121 are in a static state, and the dust collecting chamber 121 will be in a negative pressure state for a long time during the cleaning task of the cleaning device 100, resulting in the accumulation of garbage dust at the dust collection outlet 125, which is more likely to adhere to the inner wall of the dust collecting chamber 121. Moreover, when the airflow carries dust and garbage from the dust collecting air inlet 124 into the dust collecting chamber 121, the flow direction will change, but the dust and garbage will hit and stick to the inner surface of the dust collecting chamber 121 opposite to the dust collecting air inlet 124, especially wet dust and garbage, which may stick to the inner surface and cannot be carried away by the airflow. Therefore, after long-term use, the inner wall of the dust collecting chamber 121 accumulates a lot of dust and garbage, which is difficult to remove, and there may be a large number of bacteria, resulting in a poor user experience. Therefore, the dust box assembly 10 provided in the embodiment of the present application can discard the dust collecting chamber 121 as a whole, which can prevent users from contacting dirt and improve user experience. For the dust removal channel 112 that will also come into contact with dust and garbage, on the one hand, the length of the dust removal channel 112 is relatively short and the inner surface of the dust removal channel 112 is relatively flat and regular, so even if the user needs to clean it, it is relatively easier.

[0046] When the cleaning device 100 is working, the dust collecting chamber 121 may be subjected to vibration, impact of airflow carrying garbage, and sharing of air pressure applied to the dust hood 120. Therefore, the dust hood 120 needs to have a certain structural strength. Taking common plastic materials as an example, if the shell of the dust hood 120 is thicker, it needs to be made of more plastic. Although the structural strength is guaranteed, it also leads to an increase in its cost. While wasting materials, it will also cause more serious white pollution when it is discarded. Therefore, in comparison, the wall thickness of the dust hood 120 can be relatively thin, and the dust box seat 110 cooperates with the dust hood 120 to provide support for the dust hood 120, thereby ensuring its structural strength. Optionally, components such as the handheld portion 111, the parts that limit and align with the device body 20 of the cleaning device 100, the dust box filter 115 (as mentioned below) that filters the airflow output from the dust collection outlet 125, and the dust removal channel 112 that are not so easy to be contaminated can be arranged on the dust box seat 110, so that the structure of the dust hood 120 can be simplified, thereby further reducing costs. In some embodiments, the dust hood 120 can be made by processes such as blow molding and injection molding, so as to be produced in large quantities at low cost. Since it is a consumable material itself, it only needs to ensure its basic service life, so recycled plastic can be used as a raw material, thereby taking into account environmental protection and use costs. Optionally, the dust box filter 115 can also be arranged on the dust hood 120, and when the dust hood 120 is replaced, it is replaced together with the dust box filter 115.

[0047] In some embodiments, the position limiting and alignment between the dust box assembly 10 and the device body 20 can be achieved by the dust box seat 110. In this case, the requirements for the processing accuracy and mechanical strength of the dust hood 120 can be reduced. The dust hood 120, as a component that can be removed and replaced from the dust box seat 110, can reduce the processing cost of the dust hood 120. In other embodiments, the position limiting and alignment between the dust box assembly 10 and the device body 20 can be achieved by the dust hood 120. In still other embodiments, the position limiting and alignment between the dust box assembly 10 and the device body 20 can be achieved by the dust box seat 110 and the dust hood 120.

[0048] For example, Figure 3 , Fig. 7A and Figure 7BAs shown, the dust box seat 110 may include a mounting cavity 118 capable of accommodating a dust hood 120, the inlet 112a of the dust removal channel 112 is connected to the mounting cavity 118, and the dust hood 120 is detachably mounted in the mounting cavity 118. It is desirable that the dust hood 120 where the dust collection cavity 121 is located can be simply removed from the dust box seat 110, so as to facilitate the user's own handling. For example, the dust hood 120 can be installed to the dust box seat 110 by any suitable means such as snap-on, plug-in or magnetic attraction. During the disassembly process, the user can avoid contacting the dirt in the dust collection cavity 121 by contacting the dust hood 120 away from the dust collection air inlet 124, the dust collection air outlet 125 and the dust removal port 126 (such as the handle described below). In some examples, when the dust hood 120 is not seriously contaminated, the user may not discard the dust hood 120, but clean the removed dust hood 120 without cleaning the dust box assembly 10 as a whole.

[0049] exist Figure 3 , Fig. 7A and Figure 7B In the illustrated embodiment, the dust box seat 110 may include an installation cavity 118 capable of accommodating the dust hood 120, so that the dust hood 120 can be installed with the dust box seat 110 by directly inserting it into the installation cavity 118, making the installation easier and improving the convenience of operation.

[0050] In some embodiments, the dust box seat 110 and the dust hood 120 can play a certain limiting role on the dust hood 120 only through the greater friction between the walls of the two. The friction limiting role ensures that the dust box assembly 10 is installed before the storage bin 21 of the device body 20, and the relative positions of the two are fixed. After the dust box assembly 10 is installed in the storage bin 21, the dust hood 120 can be further limited by the device body 20 and / or the cover 30. The above installation method can reduce the use of various connection mechanisms such as buckles and magnetic suction, so that the structure of the dust hood 120 and the dust box seat 110 can be made simpler, thereby reducing costs.

[0051] In some other embodiments, a snap-fit ​​structure (not shown in the figure) may be provided between the dust box seat 110 and the dust hood 120. For example, a corresponding protrusion is provided on the dust hood 120, and a corresponding groove is provided on the dust box seat 110; or, a corresponding groove is provided on the dust hood 120, and a corresponding protrusion is provided on the dust box seat 110. When the dust hood 120 is installed to the dust box seat 110, the dust hood 120 may be slightly deformed, so that the protrusion is engaged with the groove. The direction in which the protrusion protrudes and extends into the groove is at an angle to the installation direction in which the dust hood 120 is installed in the dust box seat 110, so that the protrusion can prevent the dust hood 120 from being separated from the dust box seat 110 to a certain extent after the protrusion and the groove are matched. Exemplarily, the direction in which the protrusion protrudes is perpendicular to the installation direction in which the dust hood 120 is installed in the dust box seat 110. Since the buckle structure can make the dust hood 120 and the dust box seat 110 relatively fixed, the interference between the dust box seat 110 and the dust hood 120 can be smaller, so that the friction between the dust box seat 110 and the dust hood 120 can be slightly smaller. In this way, when the user installs the dust hood 120 to the dust box seat 110, or removes the dust hood 120 from the dust box seat 110, the friction resistance between the dust hood 120 and the dust box seat 110 that needs to be overcome is smaller, so that the disassembly and assembly is more labor-saving.

[0052] In addition, the dust box seat 110 surrounding the outside of the dust hood 120 can also structurally strengthen the dust hood 120, thereby allowing the wall thickness of the dust hood 120 to be thinner, thereby reducing the cost of the dust hood 120 and further reducing the replacement cost for users.

[0053] In the illustrated embodiment, the mounting cavity 118 can basically completely accommodate the dust hood 120. In some other embodiments, the mounting cavity 118 can accommodate most or less of the dust hood 120, as long as the dust hood 120 can be fixed to the dust box seat 110. In other embodiments not shown, the mounting cavity 118 may not be provided on the dust box seat 110, but the installation of the two can be achieved by any suitable connecting mechanism. Exemplarily, the connecting mechanism includes but is not limited to one or more of elastic buckles, fasteners, Velcro, etc. Of course, if not contradictory, a combination of the mounting cavity 118 and the above-mentioned connecting mechanism can also be used.

[0054] For example, FIG. 2A to FIG. 2B as well as Figure 3 As shown, the edge of the dust inlet 124 is provided with a flange 1241 bent toward the outside of the dust cover 120. The flange 1241 is spaced apart from the outer surface of the dust cover 120 to form a limiting groove C. A limiting opening 113 is provided on the dust box seat 110, and in the assembled state, the edge of the limiting opening 113 is inserted into the limiting groove C.

[0055] Combined with reference Figure 4 and FIG. 6A to FIG. 6B When the dust box assembly 10 is installed in the storage bin 21 of the device body 20, the dust collection air inlet 124 of the dust box assembly 10 and the air inlet pipe 132 of the cleaning device 100 (see Figure 1B , Figure 6A-6B ) fluid connected. Figure 1B , Figure 6A-6B The installation bin 23 and the air inlet pipe 132 on the device body 20 of the cleaning device 100 are shown. As mentioned above, the installation bin 23 is used to install a cleaning member such as a roller brush 40. In this embodiment, the air inlet pipe 132 is connected to the installation bin 23. Specifically, the first end 132a of the air inlet pipe 132 is connected to the connecting port 231 on the installation bin 23. The second end 132b of the air inlet pipe 132 can be connected to the dust inlet port 22 (see FIG. 1 ) of the storage bin 21 for accommodating the dust box assembly 10. Figure 1A and Figure 1B ). When the dust box assembly 10 is installed in place in the storage bin 21, the dust collecting air inlet 124 of the dust box assembly 10 can be close to the second end 132b of the air inlet pipe 132, so that the dust collecting air inlet 124 of the dust box assembly 10 is sealed and docked with the dust inlet 22, and the fluid is connected. The air inlet pipe 132 can be made of a soft material such as silicone, rubber, etc., so as to ensure the sealing between the second end 132b of the air inlet pipe 132 and the dust collecting air inlet 124. Exemplarily, a surrounding flange 133 is provided on the outer side surface of the second end 132b. The flange 133 can extend into the storage bin 21 and rest on the inner surface of the storage bin 21. The flange 133 can be integrated with other parts of the air inlet pipe 132, all of which are made of soft materials. When the dust box assembly 10 is installed in the receiving bin 21 , the dust box assembly 10 and the inner surface of the receiving bin 21 jointly apply a certain pressure to the flange 133 , thereby forming a reliable seal around the dust collecting air inlet 124 .

[0056] In order to provide the above-mentioned pressure to the flange 133, it is desirable to accurately limit the position of the dust box assembly 10 in the receiving bin 21 along a direction perpendicular to the dust collecting air inlet 124 (e.g., the transverse direction Y1-Y2 shown in the figure). The inner surface of the receiving bin 21 is preferably able to exert a force on the dust box assembly 10 toward the dust inlet 22 of the receiving bin 21 in the transverse direction Y1-Y2, so that the edge of the dust collecting air inlet 124 (e.g., the flange 1241) can be tightly attached to the flange 133, and the flange 133 can form a reliable seal between the edge of the dust collecting air inlet 124 and the inner surface of the receiving bin 21. Based on this, after the dust hood 120 is installed on the dust box seat 110, it is also expected that the position between the two can be reliably maintained along the transverse direction Y1-Y2. A flange 1241 bent toward the outside of the dust hood 120 is provided at the edge of the dust inlet 124, and the limiting groove C formed by the flange 1241 cooperates with the limiting opening 113 of the dust box seat 110, so that the dust hood 120 can be limited along the transverse direction Y1-Y2. Moreover, in the process of installing the dust hood 120 to the dust box seat 110, the flange 1241 can play a guiding role. On the other hand, the flange 1241 can block the dust box seat 110, thereby preventing dust and garbage from contaminating the dust box seat 110, which is not a consumable, during the operation of the cleaning device 100, increasing the cleaning difficulty for the user.

[0057] Exemplarily, the dust collecting cover 120 is detachably installed in the installation cavity 118 along the first installation direction, see Figure 3 , the first installation direction is, for example, the Z1 direction. The angle between the outer surface of the dust hood 120 where the dust inlet 124 is formed and the first installation direction can be relatively small, for example, in the range of 0 to 45 degrees. Preferably, the angle can be less than or equal to 30 degrees; further, less than or equal to 20 degrees. In the illustrated embodiment, the outer surface of the dust hood 120 at the dust inlet 124 is generally defined by the flange 1241. However, in other embodiments not shown, along the lateral direction Y1-Y2, if the position of the dust box seat 110 can be limited without relying on the limit groove C, for example, by providing a slide bar and a slide groove extending along the vertical direction Z1-Z2 on the inner surface of the mounting cavity 118 and the outer surface of the dust hood 120 to limit the relative position of the dust box seat 110 and the dust hood 120, then the flange 1241 can be omitted. That is to say, no matter what the situation is, it is expected that there is a small angle between the first installation direction and the outer surface of the dust hood 120 at the dust inlet 124. In this way, the integrity of the two side walls of the installation cavity 118 that are opposite to each other along the transverse direction Y1-Y2 can be guaranteed. Specifically, when the angle between the first installation direction and the outer surface of the dust hood 120 at the dust inlet 124 is zero, the integrity of the "two side walls" is most likely to be guaranteed. In this case, Figure 3As a reference, for example, the dust hood 120 can be inserted into the dust box seat 110 from the top, bottom, left or right, so there is no need to destroy the "two side walls". When the first installation direction is perpendicular to the outer surface of the dust hood 120 at the dust inlet 124, it is likely that the dust hood 120 will be installed in the installation cavity 118 from the front side (the direction shown in Y1). The benefit of ensuring the integrity of the "two side walls" is that along the lateral direction Y1-Y2, the dust hood 120 can be kept in the installation cavity 118 by relying on a fastened physical structure. As mentioned above, when the dust box assembly 10 is installed in place in the receiving bin 21, the outer surface of the dust hood 120 at the dust inlet 124 is also required to squeeze the flange 133 along the Y2 direction to form a reliable seal. By maintaining the dust hood 120 in the installation cavity 118 through a solid physical structure, the reaction force along the Y1 direction exerted by the flange 133 on the dust hood 120 can be prevented from squeezing the dust hood 120 out of the dust box seat 110 and hindering the dust box assembly 10 from being installed in the storage bin 21; even if the dust hood 120 is not squeezed out, it may cause the dust hood 120 to be displaced along the Y1 direction relative to the dust box seat 110, thereby causing the edge of the dust inlet 124 of the dust hood 120 to fail to tightly rest against the flange 133.

[0058] When a flange 1241 is formed at the dust collecting air inlet 124 of the dust collecting cover 120 , the angle between the first installation direction and the plane where the flange 1241 is located may be in a range of 0 to 45 degrees.

[0059] Of course, optionally, the position of the dust hood 120 relative to the dust box seat 110 along the lateral direction Y1-Y2 can also be maintained by structures such as snaps, or by relying on the combination of the snaps and the above-mentioned "solid physical structure".

[0060] Fig.11A A schematic diagram of the installation process of installing the dust collecting cover 120 in the dust box assembly provided in the embodiment of the present application to the dust box seat 110; Fig. 11B A schematic diagram of the installation process of the dust box assembly provided in the embodiment of the present application being installed into the receiving bin of the device body;

[0061] Fig. 11C This is a schematic diagram of the dust box assembly provided in the embodiment of the present application being installed in the receiving bin of the device body. Fig.11A -Attached Fig. 11C The dust box assembly 10 is configured to be mountable to the cleaning device 100 along a second mounting direction opposite to the first mounting direction.

[0062] Since the inner surface of the receiving bin 21 forms a certain clamping force on the dust box assembly 10 along the transverse direction Y1-Y2, that is, it is hoped that the dust box assembly 10 can be tightly pressed against the flange 133. Therefore, whether the dust box assembly 10 is inserted into the receiving bin 21 along the longitudinal direction X1-X2 or the vertical direction Z1-Z2, a certain friction force needs to be overcome, and the friction force is formed between the flange 1241 and the flange 133. Since the flange 1241 of the dust box assembly 10 is in frictional contact with the above-mentioned flange 133 during the process of installing the dust box assembly 10 to the receiving bin 21, based on this, if the direction in which the dust box assembly 10 is installed to the receiving bin 21 of the cleaning device 100 is the same as the direction in which the dust hood 120 is installed to the dust box seat 110, then during the installation process, the friction force applied by the flange 133 to the flange 1241 of the dust hood 120 will cause the dust hood 120 to have a tendency to fall off the dust box seat 110 in a direction opposite to the first installation direction, thereby causing the dust hood 120 to easily fall off the dust box seat 110. Therefore, in the embodiment of the present application, if the installation direction of the dust box assembly 10 to the cleaning device 100 is called the second installation direction, it is expected that the second installation direction is opposite to the first installation direction, so that in the process of installing the entire dust box assembly 10 to the storage bin 21, when overcoming the above-mentioned friction force, not only will the dust hood 120 not be separated from the dust box seat 110, but also the dust hood 120 can be more reliably installed in the desired position in the dust box seat 110, avoiding the situation that the dust collection air inlet 124 is not aligned with the dust inlet 22 due to the incomplete installation. In addition, for the illustrated embodiment, the second installation direction is generally downward, and the first installation direction is upward, so that the opening on the dust box seat 110 for installing the dust hood 120 is located at the bottom of the dust box seat 110, and when the dust box assembly 10 is installed in the storage bin 21 of the device body 20, the opening of the dust box seat 110 is not visible, thereby ensuring the integrity of the top surface of the dust box seat 110 and avoiding affecting its appearance.

[0063] For example, Figure 3As shown, when the angle between the first installation direction (Z1 direction) and the plane where the flange 1241 is located is within the range of 0 to 45 degrees, along the first installation direction, the plane where the flange 1241 is located is inclined toward the outside of the dust hood 120. For the illustrated embodiment, along the lateral direction Y1-Y2, at the dust inlet 124, the dust box assembly 10 is formed into a shape that is wide at the top and narrow at the bottom, so that it can also play a guiding role in the process of installing the dust box assembly 10 into the storage bin 21. On the other hand, since the plane where the flange 1241 is located is inclined toward the outside of the dust hood 120, the width of the limiting groove C in the lateral direction Y1-Y2 can also be gradually increased, and the limiting groove C that is wide at the top and narrow at the bottom is formed between the flange 1241 and the outer surface of the dust hood 120. In this way, the edge of the limiting opening 113 can also play a guiding role when it is inserted into the limiting groove C from top to bottom, so that the dust hood 120 can be more smoothly and conveniently installed in the installation cavity 118 of the dust box seat 110.

[0064] Exemplarily, the dust collection air inlet 124 can be located on the side of the dust hood 120. The "side of the dust hood 120" described here, and the "side of the dust box seat 110" to be mentioned below, and their "top surface", "bottom surface", "upper" and "lower" are all relative to the dust box assembly 10 installed on the cleaning device 100, and the orientation of the cleaning device 100 in a normal use state. In order to clearly describe the structure of the dust hood 120, the side of the dust hood 120 is generally connected between the top surface and the bottom surface, and surrounds the dust collection chamber 121. In addition, it should be noted that the side, top surface and bottom surface of the dust hood 120 are not necessarily flat. In the case where part of the structure of the dust hood 120 is in direct contact with the receiving bin 21, the shape of the part of the dust hood 120 in contact with the receiving bin 21 can be designed according to the shape of the receiving bin 21, and the part of the dust hood 120 in contact with the dust box seat 110 can be designed to fit the shape of the dust box seat 110. The top surface, the bottom surface and the side surfaces of the dust collecting cover 120 together surround and form a dust collecting chamber 121 .

[0065] It should be noted that the description of the first installation direction and the second installation direction above are all relative to the embodiment in which the dust collection air inlet 124 is located on the side of the dust collection cover 120. Optionally, the dust collection air inlet 124 may also be located on the top surface and the bottom surface of the dust collection cover 120. In this case, the first installation direction and the second installation direction may be substantially parallel to the transverse direction Y1-Y2 or the longitudinal direction X1-X2.

[0066] In the case where the dust collection air inlet 124 is located on the side of the dust collection cover 120, the limiting opening 113 can be located on the side of the dust box seat 110. Figure 8The dust collection air inlet 124 can be arranged on the first side surface (facing the Y2 direction) of the dust collection end 122. The dust collection cover 120 is detachably installed from the bottom of the dust box seat 110 to the installation cavity 118, which can ensure the integrity of the top surface of the dust box seat 110 and avoid affecting its appearance; and, as mentioned above, in conjunction with the second installation direction of the existing dust box assembly 10 installed on the cleaning device 100, the dust collection cover 120 can be reliably positioned in the dust box seat 110.

[0067] In addition, if Figure 2A , Figure 3 as well as Fig. 7A As shown, the dust box assembly 10 may be provided with a handheld portion 111 for the user to remove the dust box assembly 10 from the storage bin 21 of the cleaning device 100. The dust collecting cover 120 is installed from the bottom of the dust box seat 110, and the upper surface of the dust box assembly 10 may be entirely a dust box seat 110 with high strength. The handheld portion 111 may be arranged on the upper surface of the dust box seat 110, and may be located in the middle position of the longitudinal direction X1-X2 of the dust box seat 110. Setting the handheld portion 111 in the middle position may include setting the handheld portion 111 at the geometric center of the upper surface of the dust box seat 110, or may include setting the handheld portion 111 at any position on the center line extending along the transverse direction Y1-Y2 of the upper surface of the dust box seat 110. In the process of the user removing the dust box assembly 10, the force of the dust box assembly 10 can be evenly dispersed, thereby preventing the dust box assembly 10 from tilting in one direction during the disassembly process and getting stuck in the storage bin 21. In addition, the dust hood 120 is disposed below the dust box seat 110 to prevent the user from accidentally removing only the dust hood 120 when removing the dust box assembly 10 from the cleaning device 100 .

[0068] For example, Figure 4 , Figure 5B and Figure 7B As shown, the inlet 112a of the dust removal channel 112 of the dust box seat 110 can be located on the side of the installation cavity 118. The dust removal channel 112 can be bent downward in the direction from the end where the inlet 112a is located to the end where the outlet 112b is located. In this way, when the cleaning device 100 is placed on the cleaning base station 200 and performs the dust removal operation, after the dust and garbage in the dust box assembly 10 enters the dust removal channel 112 from the inlet 112a of the dust removal channel 112, the dust and garbage can use their own gravity to smoothly leave the dust collection cavity 121.

[0069] Please refer to the attached Fig.13A and Fig. 13BFor the self-moving cleaning robot, it can rely on its own driving force to move on the surface to be cleaned, and rely on its own driving force to move into the cleaning base station 200. Usually, the movement direction of the self-moving cleaning robot to the cleaning base station 200 is set, for example, the direction opposite to the movement direction of the self-moving cleaning robot when it normally cleans the surface to be cleaned. Exemplarily, the direction in which the self-moving cleaning robot enters the cleaning base station 200 is the backward direction. The two ends of the suction channel 203 on the cleaning base station 200 are respectively connected to the base station docking interface 2031 and the dust storage component 201.

[0070] Generally speaking, in order to facilitate the cleaning device 100 to enter the cleaning base station 200, the cleaning base station 200 will be set with a certain slope, so that the cleaning device 100 can climb to the cleaning base station 200, which can be called a "slope pad" in this application, and the base station docking interface 2031 is usually set at the slope pad. Fig.13A and Fig. 13B By comparison, if the base station docking interface 2031 is arranged closer to the outside of the cleaning base station 200, the height dimension of the lower horizontal channel of the suction channel 203 on the cleaning base station 200 will be smaller, which makes it easier to cause garbage blockage ( Fig. 13B The thick black dot in the middle indicates the state of garbage blocking). Therefore, it is desirable that the position of the base station docking interface 2031 be designed to be closer to the inner side of the cleaning base station 200 to ensure the height dimension of the suction channel 203. Once the position of the base station docking interface 2031 of the cleaning base station 200 is determined, the position of the cleaning device docking interface 1011 on the cleaning device 100 that docks with the base station docking interface 2031 is also determined. Therefore, it is necessary to design the cleaning device docking interface 1011 to be closer to the inner side of the cleaning base station 200 (for example, in the state of garbage blocking). Fig.13A On the premise of the position of the cleaning device docking interface 1011 and the position of the cleaning device docking interface 1011, the outlet 112b of the dust removal channel 112 of the dust box assembly 10 is accurately docked with the cleaning device docking interface 1011.

[0071] In some embodiments, Figure 4 As shown, combined with Figure 1B The dust box assembly 10 is provided with a dust box filter 115 at the dust collecting air outlet 125, and the dust box filter 115 is connected to the fan, and the dust and garbage are sucked into the dust collecting chamber 121 under the suction force of the fan. In order to ensure that the dust box assembly 10 has a sufficient volume, the fan is usually arranged at the rear of the dust box assembly 10 ( Figure 2B In order to ensure that the dust box assembly 10 has a sufficient filtering effect, the dust box filter 115 is folded so that the overall thickness F is relatively thick. Figure 4 and 5A, thus, the thickness dimension of the dust box filter 115 occupies more of the dimension in the transverse direction Y1-Y2 of the entire dust box assembly 10. For example, the thickness dimension of the dust box filter 115 occupies 1 / 4 of the dimension in the transverse direction Y1-Y2 of the entire dust box assembly 10, so that the dust removal port 126 of the dust collecting cover 120 and the inlet 112a of the dust removal channel 112 of the dust box seat 110 in the embodiment of the present application can only be relatively closer to the front of the dust box assembly 10. As described in the above paragraph, since the outlet 112b of the dust removal channel 112 of the dust box assembly 10 needs to be precisely docked with the cleaning device docking interface 1011, the outlet 112b of the dust removal channel 112 is closer to the rear of the dust box assembly 10. Therefore, along the front-to-back direction of the cleaning device 100, the outlet 112b of the dust removal channel 112 is closer to the rear of the cleaning device 100 than the inlet 112a of the dust removal channel 112. For the dust box assembly 10, the inlet 112a of the dust removal channel 112 and the outlet 112b of the dust removal channel 112 are offset in the transverse direction Y1-Y2. Specifically, the direction from the inlet 112a to the outlet 112b of the dust removal channel 112 can be bent backwards.

[0072] It should be noted that in the embodiment of the present application, the "front" and "rear" refer to the forward direction of the cleaning device 100 when it is working normally on the surface to be cleaned, and the backward direction. In other words, for the cleaning device 100 with a mopping member, the mopping member is usually arranged at the rear of the cleaning device 100, and the dust box assembly 10 is arranged in front of the mopping member. When the cleaning device 100 enters the cleaning base station 200 in the backward direction, the dust removal channel 112 can be bent along the rear.

[0073] Based on the fact that the dust removal passage 112 is bent backward from the end where the inlet 112a is located to the end where the outlet 112b is located, it may be necessary for the bottom of the dust removal passage 112 (i.e., the portion where the outlet 112b is located) to protrude from the mounting cavity 118 of the dust collecting cover 120. Figure 2B and Figure 3 As shown. The inlet 112a of the dust removal channel 112 is located at the end of the dust collection end 122 in the length direction of the dust collecting hood 120, and a one-way valve 116 can be provided at the inlet 112a of the dust removal channel 112. The one-way valve 116 is configured to remain in a closed state during the above-mentioned "dust collection" process, and to remain in an open state toward the dust removal channel 112 under the action of the dust removal airflow during the above-mentioned "dust removal" process. Since the one-way valve 116 needs to be rotated to open in the dust removal channel 112, it is necessary to ensure that there is at least space for the one-way valve 116 to open in the dust removal channel 112. In the embodiment of the present application, the bottom of the dust removal channel 112 (i.e., the part where the outlet 112b is located) protrudes from the mounting cavity 118 of the dust collecting hood 120, so that the opening of the one-way valve 116 is not hindered.

[0074] The following is combined with Figure 5A , explaining the specific reason why the bottom of the dust removal channel 112 (i.e., the part where the outlet 112b is located) needs to protrude from the mounting cavity 118 of the dust hood 120: As mentioned above, in order to ensure docking with the cleaning equipment docking interface 1011 and the base station docking interface 2031, due to the reasons mentioned above, the position of the base station docking interface 2031 is restricted, and then the position of the cleaning equipment docking interface 1011 is also restricted. Therefore, the position of the outlet 112b of the dust removal channel 112 in the front-to-back direction of the cleaning equipment 100 cannot be changed. In the case where the position of the outlet 112b of the dust removal channel 112 in the front-to-back direction of the cleaning device 100 cannot be changed, if the outlet 112b of the dust removal channel 112 does not protrude from the mounting cavity 118, the outlet 112b of the dust removal channel 112 will be located at the thick dashed line portion in the dashed line M2 in the figure (the thick dashed line portion in the dashed line M2 is the position of the outlet 112b when the outlet 112b is assumed to be flush with the bottom of the mounting cavity 118), and in order to ensure that dust passes more smoothly in the dust removal channel 112, the transition between the side walls is usually a rounded transition. Based on the above, if the outlet 112b is located at the thick dashed line position in the dashed line M2 in the figure, the upper side wall N2 of the dust removal channel 112 will be further offset to the right as shown in the figure, thereby occupying more of the upper space of the dust removal channel 112, thereby affecting the opening of the one-way valve 116. In the embodiment of the present application, the outlet 112 b of the dust removal channel 112 protrudes from the installation cavity 118 , thereby preventing the upper side wall of the dust removal channel 112 from affecting the opening of the one-way valve 116 .

[0075] Based on this, Fig. 12A and Figure 2B As shown, a protruding handle 128 is provided at the bottom of the dust hood 120. The bottom of the handle 128 is flush with the bottom of the dust removal channel 112. In this way, when installed in an existing storage bin 21 with a flat bottom, the bottom of the storage bin 21 can limit the dust hood 120 through the handle 128 to prevent it from leaving the desired position. Of course, optionally, as Fig. 12B As shown, the dust hood 120 can also be extended downward to increase the depth of the dust hood 120 so that the bottom of the dust hood 120 is flush with the bottom of the dust removal channel 112, which plays a role in limiting the dust hood 120 when installed in the storage bin 21 with a flat bottom surface. However, as analyzed above, the dust removal channel 112 is bent downward in the direction from the end where the inlet 112a is located to the end where the outlet 112b is located, and the bottom is convex. Fig. 12BIn that case, increasing the depth of the dust hood 120 to make up for the height difference formed by the bend of the dust removal channel 112 may cause the bottom surface of the dust collection chamber 121 in the dust hood 120 to be lower than the entrance 112a of the dust removal channel 112. In this way, when performing the dust removal operation, the dust and garbage at the bottom of the dust collection chamber 121 will not be cleaned up along the dust removal channel 112, resulting in a sanitary dead corner. The handle 128 is used at the bottom of the dust hood 120 to make up for the height difference formed by the bend of the dust removal channel 112, which not only solves the problem of sanitary dead corners, but also facilitates the installation and removal of the dust hood 120 relative to the dust box seat 110.

[0076] Since the dust removal channel 112 is curved as described above, and its inlet 112a and outlet 112b face different directions respectively, the dust removal channel 112 needs to occupy a certain dimension of the dust box assembly 10 along the length direction (i.e., the longitudinal direction X1-X2) of the dust box assembly 10. The dimension of the dust collecting cavity 121 along the length direction of the dust box assembly 10 is greater than half of the length of the dust box assembly 10. In this way, it can be ensured that the dust collecting cavity 121 has a sufficiently large space.

[0077] The dust hood 120 can be made by injection molding, thereby ensuring its structural strength and matching accuracy while taking into account the cost. The handle 128 protrudes from the surface of the dust hood 120, which can ensure the flatness of the inner surface of the dust collecting cavity 121 in the dust hood 120, which can not only greatly reduce the difficulty of demolding the dust hood 120, so that fewer molds can be used, thereby reducing the mold opening cost; but also avoid the residual garbage and dust in the dust collecting cavity 121.

[0078] For example, see Figures 8 to 10 The limiting groove C between the flange 1241 and the outer surface of the dust collecting hood 120 may include a first limiting groove section 1242 and a second limiting groove section 1243, the first limiting groove section 1242 and the second limiting groove section 1243 extend along a first installation direction in which the dust collecting hood 120 is installed in the installation cavity 118, and the first limiting groove section 1242 and the second limiting groove section 1243 are respectively located on opposite sides of the dust collecting air inlet 124.

[0079] As described above, during the process of installing the dust box assembly 10 into the receiving bin 21, since the flange 133 on the air inlet pipe 132 will generate pressure on the flange 1241 of the dust hood 120, the limiting grooves C are preferably symmetrically arranged, that is, the first limiting groove section 1242 is arranged on one side of the dust inlet 124, and the second limiting groove section 1243 is correspondingly arranged on the other side of the dust inlet 124. In this way, when the dust hood 120 is installed on the dust box seat 110, the two side edges of the limiting opening 113 can be inserted into the limiting grooves C, respectively supporting the flange 1241 of the first limiting groove section 1242 on one side of the dust inlet 124 and the flange 1241 of the second limiting groove section 1243 on the other side of the dust inlet 124, so as to prevent a large turning moment from being formed on one side of the flange 1241, causing the flange 1241 to break. Exemplarily, along the first installation direction, the widths of the first limiting groove section 1242 and the second limiting groove section 1243 gradually decrease. Optionally, in the process of gradually installing the dust hood 120 to the dust box seat 110, the resistance formed by the first limiting groove section 1242 and the second limiting groove section 1243 on both sides to the edge of the limiting opening 113 can be gradually increased until it cannot be pushed. In this way, the resistance gradually increases during the installation process, so the user can be prompted to avoid over-installation and damage to the relatively fragile dust hood 120. The widths of the first limiting groove section 1242 and the second limiting groove section 1243 gradually decrease, so that in the process of the edge of the limiting opening 113 being stuck in the first limiting groove section 1242 and the second limiting groove section 1243, it can also guide the edge of the limiting opening 113, thereby simplifying the installation; and avoiding the skewness of the dust hood 120 during installation.

[0080] Exemplarily, the limiting groove C may further include a third limiting groove section 1244, which is connected between the ends of the first limiting groove section 1242 and the second limiting groove section 1243 along the first installation direction, so that the three side edges of the limiting opening 113 are inserted into the limiting groove C. As described above, the ends of the first limiting groove section 1242 and the second limiting groove section 1243 ( Figure 8 The lower end of the limit slot 1240 is gradually reduced. When the two side edges of the limit opening 113 are respectively the first limit slot section 1242 and the second limit slot section 1243, if the user is not prompted to stop in time, the user continues to apply insertion force to the dust cover 120, which may cause the flange 1241 forming the first limit slot section 1242 and the second limit slot section 1243 to be damaged. Therefore, the first limit slot section 1242, the second limit slot section 1243 and the third limit slot section 1244 can correspond to the first side edge 113A, the second side edge 113B and the third side edge 113C of the limit opening 113 (see Fig. 7A) A total of three side edges cooperate to prevent the other two edges of the limiting opening 113 from being inserted into the first limiting groove section 1242 and the second limiting groove section 1243 to a greater depth, resulting in the flange 1241 being broken. In addition, the third limiting groove section 1244 can also play a limiting role along the first installation direction. When the dust collecting cover 120 is inverted and installed relative to the dust box seat 110, the third side edge 113C of the limiting opening 113 is inserted to the bottom of the third limiting groove section 1244.

[0081] For example, return reference Figures 2A to 4 The dust box seat 110 may be provided with a dust box outlet, the dust box outlet is connected to the dust collecting outlet 125, and a dust box filter 115 is provided at the dust box outlet. As mentioned above, when the cleaning device 100 uses a negative pressure device to collect dust and garbage into the dust collecting chamber 121, the dust collecting outlet 125 can be connected to a negative pressure device such as a fan through the dust box outlet provided on the dust box seat 110. The dust box outlet may be covered with a dust box filter 115. The dust box filter 115 can ensure that only clean air leaves the dust collecting chamber 121 and enters the negative pressure device, thereby preventing dust and garbage from damaging the negative pressure device.

[0082] Exemplarily, a one-way valve 116 is disposed on the dust box seat 110 and at the inlet 112a of the dust removal passage 112, and the one-way valve 116 can be opened along the direction from the inlet 112a to the outlet 112b of the dust removal passage 112. Figure 4 and FIG. 5A to FIG. 5B , a one-way valve 116 can be arranged in the dust removal channel 112. The one-way valve 116 can be opened unidirectionally under the action of the airflow from the dust collecting chamber 121 to the dust removal channel 112, so that the dust collecting chamber 121 is fluidically connected to the cleaning device docking interface 1011 on the cleaning device 100, so that the garbage in the dust collecting chamber 121 can be transferred to the dust storage assembly 201 of the cleaning base station 200. When the one-way valve 116 is closed, the dust removal channel 112 is isolated from the dust collecting chamber 121. The one-way valve 116 can be opened in the direction of the dust removal channel 112. When the cleaning device 100 performs cleaning work, the negative pressure device forms a negative pressure in the dust collecting chamber 121, and the negative pressure can reliably close the one-way valve 116 to prevent dust and garbage from falling from the dust removal channel 112.

[0083] For example, Figure 4As shown, the dust outlet 125 may be covered with a filter 1251. The filter 1251 may include a mesh structure made of non-woven fabric, plastic, etc. In some exemplary embodiments, the filter 1251 may be pasted on the dust outlet 125 and discarded as a consumable with the dust cover 120. In a preferred embodiment, the filter 1251 may be installed on the inner side of the dust outlet 125 by hot pressing, bonding, etc., that is, installed in the dust collecting chamber 121, so as to prevent it from being squeezed and falling by dust and garbage. The filter 1251 preliminarily blocks the dust and garbage in the dust collecting chamber 121. The dust box filter 115 may include a HEPA filter, which can filter fine dust and garbage that the filter 1251 cannot filter. The filter 1251 is provided, which can greatly extend the service life of the dust box filter 115 with relatively high cost, and the filter 1251 has relatively low cost and can be replaced or cleaned frequently. The provision of the filter screen 1251 and the dust box filter 115 can effectively reduce the user's usage cost while ensuring the filtering effect.

[0084] For example, the area of ​​the dust box filter 115 is smaller than the area of ​​the dust collection outlet 125, and further larger than the area of ​​the filter 1251. In this way, the filter 1251 has greater permeability, and the air resistance of the dust box filter 115 is greater under the same area. Therefore, increasing the area of ​​the dust box filter 115 can make the ventilation flow of the dust box filter 115 and the filter 1251 match.

[0085] As described above, the dust hood 120 can be formed by injection molding or blow molding. For the dust hood 120, since there are multiple openings on it, when using the blow molding process, a closed embryo of the dust hood 120 with only one air inlet can be first made, and then the material at the opening can be cut off to achieve one-piece molding. In contrast, the dust hood 120 with an opening can be directly molded by the injection molding process. However, since the dust hood 120 includes a dust collection cavity 121 that is larger than the opening on its surface, it is difficult to make it by one-piece molding considering the demolding factor.

[0086] Exemplarily, the dust hood 120 may include a plurality of hood parts, and the plurality of hood parts are enclosed to form a dust collecting chamber 121. As described above, it is very difficult to form the dust hood 120 by one-time demolding, and there are also high requirements for the design and precision of the mold. In contrast, the dust hood 120 can be split into a plurality of separate hood parts, each hood part is molded by injection molding, and finally assembled to form a complete dust hood 120, which can greatly simplify the process and reduce the mold cost. The split position of the dust hood 120 (i.e., the interface between the plurality of hood parts) should consider both its demolding situation and the structural strength after assembly. Injection molding can be used for each hood part. Of course, the present application does not exclude embodiments in which one or more hood parts of the dust hood 120 are molded by a blow molding process and other hood parts are molded by an injection molding process.

[0087] Exemplarily, each cover part can be integrally formed with a buckle 127, and multiple cover parts are interconnected by the buckle 127. Compared with connecting multiple cover parts by heating bonding or adhesive, the connection using the buckle 127 can be completed with a simple operation, without the need for a heating component, nor consumables and workstations such as adhesives or dispensing machines, and even multiple cover parts do not need to be assembled, and can be sold directly as final products. Not only does it greatly reduce the production and assembly costs, but the use of the buckle 127 for fixing is more environmentally friendly than adhesives, and it is less likely to produce defective products, and the structure is relatively firm. In addition, the buckle 127 can realize a detachable connection between multiple cover parts. If the user needs, the multiple cover parts can also be disassembled to thoroughly clean the inside of the dust hood 120.

[0088] Exemplarily, the plurality of cover parts may include a first cover part 120A and a second cover part 120B, and the interface between the first cover part 120A and the second cover part 120B is located at the top surface, the bottom surface, the first side surface and the second side surface of the dust collecting cover 120. The first side surface is the side surface provided with the dust collecting air inlet 124, and the second side surface is arranged opposite to the first side surface along the width direction of the dust collecting cover 120 (for example, the transverse direction Y1-Y2 shown in the figure). Figure 8, in the placement orientation shown in the figure, the first side is the side facing the outside of the paper, and the second side is the side facing the inside of the paper. It is easy to understand that disassembling the dust hood 120 into two hood parts can simplify the structure of each hood part, and the corresponding mold is also simpler. But at the same time, the number of required molds also increases accordingly. Therefore, compared with simplifying the structure of the mold, reducing the number of molds can usually reduce costs more effectively. Taking into account the number of molds and the difficulty of processing the molds, the dust collecting chamber 121 is formed by enclosing two hood parts, so that both hood parts can be formed by relatively simple molds. In contrast, the difficulty and cost of one-piece molding using one mold are much higher than using two molds. Using more molds will also increase costs and make assembly difficult. Of course, in other embodiments not shown, there may be more hood parts.

[0089] Exemplarily, the interface between the first cover portion 120A and the second cover portion 120B can be arranged horizontally (e.g., perpendicular to the vertical direction Z1-Z2), or vertically (e.g., perpendicular to the longitudinal direction X1-X2, or perpendicular to the transverse direction Y1-Y2). As mentioned above, the dust hood 120 has a longitudinally long structure. The interface between the first cover portion 120A and the second cover portion 120B is designed to be perpendicular to the longitudinal direction X1-X2, which can shorten the circumference of the interface between the two, thereby enhancing the mechanical strength and reducing the requirements for sealing at the interface between the two.

[0090] Exemplarily, at least at the interface located at the bottom surface of the dust hood 120, the entire edge of the first cover part 120A and the entire edge of the second cover part 120B are provided with a continuously extended inverted structure, so that the first cover part 120A and the second cover part 120B are plugged into each other through the inverted structure. The inverted structure includes a first part 1291 and a second part 1292, and the first part 1291 can be arranged on the first cover part 120A, and the second part 1292 can also be arranged on the second cover part 120B accordingly. The inverted structure allows one of the first part 1291 and the second part 1292 to be inserted into the other, thereby achieving a good sealing effect. Therefore, it is expected that the inverted structure can be arranged at the entire bottom edge of the first cover part 120A and the second cover part 120B at the interface, so that even if there is liquid in the dust hood 120, it will not leak.

[0091] Exemplarily, the dust collecting air inlet 124 can be formed by the first cover part 120A and the second cover part 120B. As described above, the first limiting groove section 1242 and the second limiting groove section 1243 are respectively provided on both sides of the dust collecting air inlet 124. After the limiting opening 113 cooperates with the first limiting groove section 1242 and the second limiting groove section 1243, the first cover part 120A and the second cover part 120B can also be limited in the longitudinal direction X1-X2, so that the buckle 127 connecting the two cover parts will not be subjected to a large force, thereby ensuring the service life of the buckle 127 and avoiding the problem of the buckle 127 breaking and garbage falling when the user disassembles the dust collecting cover 120. Fig.10 As shown, under normal circumstances, a dust shield 130 may be provided on the dust collecting air inlet 124. The dust shield 130 may be made of a soft material. When the airflow enters the dust collecting chamber 121 through the dust collecting air inlet 124, the dust shield 130 swings toward the dust collecting chamber 121, and basically no wind resistance is generated. When the airflow stops, the dust shield 130 falls under the action of gravity to prevent dust and garbage from escaping the dust collecting chamber 121. The dust collecting air inlet 124 is formed by the first cover part 120A and the second cover part 120B, and the installation of the dust shield 130 can also be facilitated. Exemplarily, hanging parts 1245 are respectively provided in the first cover part 120A and the second cover part 120B. Both sides of the top of the dust shield 130 can be hung on the hanging parts 1245.

[0092] According to another aspect of the present invention, a dust collecting hood is provided. The dust collecting hood has the structure of any one of the above embodiments, which will not be described in further detail herein for the sake of brevity.

[0093] According to another aspect of the present invention, there is provided a cleaning device 100 comprising any one of the above-mentioned dust box assemblies 10. The cleaning device 100 comprises at least one of the following: a self-propelled cleaning robot, a handheld vacuum cleaner.

[0094] For example, the cleaning device 100 may further include a dust collecting fan, and the air inlet of the dust collecting fan may be connected to the dust collecting outlet. The roller brush assembly may include a rotatable roller brush 40, which contacts the surface to be cleaned and rotates to lift up dust and garbage on the surface to be cleaned. In this process, the suction negative pressure generated by the dust collecting fan may suck the dust and garbage into the dust box assembly 10, thereby realizing the collection of dry garbage on the surface to be cleaned.

[0095] According to another aspect of the present invention, a cleaning system is provided. Fig.14A and Fig. 14BAs shown, the cleaning system may include a cleaning base station 200 and any of the cleaning devices 100 described above. A dust storage assembly 201 and a dust removal fan 202 may be provided in the cleaning base station 200. The air inlet of the dust removal fan 202 is communicated with the dust storage assembly 201, and is used to form a negative pressure in the dust storage assembly 201. The cleaning device 100 may be selectively docked with the cleaning base station 200. The cleaning base station 200 can charge the cleaning device 100, and when the cleaning device 100 is docked with the cleaning base station 200, the inlet of the dust storage assembly 201 may be communicated with the outlet 112b of the dust removal channel 112 of the dust box assembly 10 of the cleaning device 100. Those skilled in the art may configure the functions of the cleaning base station 200 according to user needs. After the dust removal fan 202 is started, a negative pressure may be formed in the dust storage assembly 201, so that the dust and garbage in the dust collection chamber 121 is transferred to the dust storage assembly 201 through the suction channel 203 and the dust removal channel 112. The cleaning system adopts all the technical solutions of all the above-mentioned dust box components 10 and cleaning device 100 embodiments, and therefore has at least all the beneficial effects brought by the technical solutions of the above-mentioned dust box components 10 and cleaning device 100 embodiments, which will not be described one by one here.
