Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle technical field, concretely relates to a dust box, dust collection device, cleaning equipment and cleaning system. BACKGROUND

[0002] The working principle of the dust collection of the sweeper includes that the high-speed rotation of the blade driven by the motor generates air negative pressure in the sealed dust box, the surface of the object such as carpet and floor with dust is sucked, the dust is sucked into the filter assembly together with the air, the dust is filtered by the filter element in the filter assembly and is collected by the dust box, and the clean air after filtration is discharged outside the sweeper body.

[0003] After the filter element works for a period of time, a large amount of dust is adsorbed on the surface of the filter element at the side where the dust enters, and a large amount of dust adhered to the surface of the filter element will block the small filter screen holes on the surface of the filter element, thereby affecting the filtering capacity of the filter element. After the filter element is blocked, the filter element is cleaned after disassembly or a new filter element is replaced after disassembly, and no matter which way is used, a large amount of cleaning time will be spent, and the latter will directly lead to the replacement cost of consumables. UTILITARY MODEL CONTENT

[0004] The utility model provides a dust box, dust collection device, cleaning equipment and cleaning system to realize the self-cleaning function of the filter assembly, and improve the technical problems of long manual cleaning time and high replacement cost.

[0005] To achieve the above object and other related objects, the utility model provides a dust box in the first aspect, the dust box is installed in the cleaning equipment, and the dust box comprises a box body and a filter assembly; the filter assembly is installed in the box body, the inner cavity of the box body is divided into a first chamber and a second chamber, the first chamber and the second chamber are communicated through the aperture of the filter assembly; the wall body of the first chamber is provided with an openable dust suction port and an openable dust discharge port, the wall body of the second chamber is provided with an openable air blowing port and an openable air suction port; in response to the opening of the air blowing port and the dust discharge port, the filter assembly is cleaned.

[0006] In the above technical solution, the housing is divided into a first chamber and a second chamber by a filter assembly. The wall of the first chamber is provided with an openable and closable dust suction port, and the wall of the second chamber is provided with an openable and closable exhaust port. When the exhaust port and the dust suction port are opened, the dust suction port, the first chamber, the second chamber, and the exhaust port form a dust suction channel. This allows airflow to draw dust and debris into the dust suction port and retain it in the first chamber through the filter assembly. Simultaneously, after being filtered by the filter assembly, clean air enters the second chamber through the pores and exits through the exhaust port. Furthermore, the wall of the second chamber is provided with an openable and closable air blowing port, and the wall of the first chamber is provided with an openable and closable dust discharge port. When the air blowing port and the dust discharge port are opened, the air blowing port, the second chamber, the first chamber, and the dust discharge port form a dust discharge channel. Airflow is blown into the second chamber through the air outlet, and then through the pores of the filter assembly into the first chamber. This blows dust and debris adhering to the pores and the side of the filter assembly facing the first chamber into the first chamber, where it is then discharged through the dust outlet located in the first chamber. This design achieves a self-cleaning function for the filter assembly, reducing the frequency of cleaning and lowering the replacement cost of the filter assembly.

[0007] In one embodiment of the dust box of this utility model, the air outlet is sealed with an air inlet channel, which connects the air outlet and the outside of the cleaning device; in response to the opening of the air outlet and the dust outlet, an airflow channel is formed between the air inlet channel and the dust outlet, and the airflow channel guides the airflow from the outside of the cleaning device to the filter component from the air outlet.

[0008] In the above technical solution, the air inlet channel allows for communication between the air outlet on the dust box and the outside of the cleaning equipment. When the air outlet and dust outlet are open, an airflow channel is formed between the air inlet channel and the dust outlet. This arrangement facilitates guiding airflow from outside the cleaning equipment into the dust box, thereby reducing the impact on other components inside the cleaning equipment.

[0009] In one embodiment of the dust box of this utility model, an openable and closable baffle is provided in the air inlet channel to control the opening and closing of the air outlet.

[0010] In the above technical solution, the wind deflector is set in the air inlet channel, which has sufficient installation space and allows for a wider variety of structural forms for driving the wind deflector to open and close, reducing processing difficulty and production costs.

[0011] In one embodiment of the dust box of this utility model, a drive mechanism is provided on the outside of the air inlet channel. The drive mechanism drives the baffle to open or close, so as to control the opening and closing of the air outlet.

[0012] In the above technical solution, the drive mechanism is set outside the air inlet channel, which can realize the installation of the drive mechanism inside the cleaning equipment, make full use of the internal space of the cleaning equipment, and improve the appearance of the cleaning equipment.

[0013] In one embodiment of the dust box of this utility model, the upper end of the box body has an opening, and an openable and closable box cover is connected to the opening. The first chamber is located below the second chamber.

[0014] In the above technical solution, the opening is located at the top of the housing, and an openable lid is connected to the opening. This design allows the lid to be opened and the filter removed for cleaning or replacement without removing the dust box. Furthermore, by placing the first chamber below the second chamber, dust particles can automatically fall into the first chamber (which serves as a dust storage space) under their own weight, without external force, and also reduces the amount of dust adhering to the filter assembly. Placing the second chamber above the first chamber ensures that airflow from the air outlet blows dust particles adhering to the filter assembly into the first chamber, preventing them from re-adhering to the filter assembly.

[0015] In one embodiment of the dust box of this utility model, the wall of the first chamber includes an inclined wall that gradually slopes from top to bottom into the first chamber, the dust suction port is disposed on the inclined wall, and an openable first baffle is installed on the inner side of the inclined wall, the first baffle covering the dust suction port.

[0016] In the above technical solution, the wall of the first chamber includes an inclined wall, on which the suction port is located, and an openable and closable first baffle is provided on the inner side of the inclined wall. This allows the first baffle to close under its own weight when no external suction is required, preventing dust from flowing out of the suction port. Simultaneously, it can be opened by using external suction force to counteract gravity, allowing for suction operations. This structural design is simple, low-cost, and occupies little space.

[0017] In one embodiment of the dust box of this utility model, at least one locking member is provided on the outer periphery of the box body. The locking member includes a connecting arm and a protrusion provided on the connecting arm. Under the action of external force, the connecting arm drives the protrusion to move closer to the box body, and under its own elasticity, it drives the protrusion away from the box body, so as to be used for external locking.

[0018] In the above technical solution, the locking component can fix the box inside the cleaning equipment. The combination of the connecting arm and the protrusion has the effects of ingenious structure, simple operation and reliable locking.

[0019] In one embodiment of the dust box of this utility model, at least one limiting part is provided on the outer periphery of the box body. The limiting part includes a groove that is recessed into the inside of the box body. The groove cooperates with the outside to limit the position of the box body.

[0020] In the above technical solution, the limiting part can limit the position of the dust box. On the one hand, it facilitates installation guidance and improves installation efficiency; on the other hand, the groove-shaped limiting part can cooperate with external structural components to restrict multiple degrees of freedom of the dust box, improving the firmness and reliability of the dust box installation in the cleaning equipment.

[0021] A second aspect of this utility model also provides a vacuuming device, which includes a suction generator and a dust box as described above, wherein the suction generator is connected to an exhaust port.

[0022] In the above technical solution, the dust collection device including the dust box realizes the self-cleaning function of the filter component, reduces the number of cleaning times, and also reduces the replacement cost of the filter component.

[0023] A third aspect of this utility model also provides a cleaning device, which includes a base and the aforementioned vacuuming device, the base having a mounting position, and the vacuuming device being detachably mounted in the mounting position.

[0024] In the above technical solution, the cleaning equipment including the vacuuming device realizes the self-cleaning function of the filter component, reduces the number of cleaning times, and also reduces the replacement cost of the filter component.

[0025] In one embodiment of the cleaning device of this utility model, the base further includes a first vent, a second vent, and a third vent disposed on the outer surface and at the bottom of the base. The first vent is connected to the air blowing port, the second vent is connected to the dust exhaust port, and the third vent is connected to the dust suction port.

[0026] In the above technical solution, by providing a first vent on the outer surface of the cleaning equipment that communicates with the air outlet, airflow is introduced into the dust box to clean the filter components. By providing a second vent on the outer surface of the cleaning equipment that communicates with the dust exhaust port, dust temporarily stored in the first chamber is collected and discharged outside the cleaning equipment, thus self-cleaning the dust box. By providing a third vent at the bottom of the cleaning equipment that communicates with the suction port, the surface in contact with the bottom of the cleaning equipment is cleaned.

[0027] A fourth aspect of this utility model also provides a cleaning system, which includes the above-described cleaning equipment and a base station adapted to the cleaning equipment.

[0028] The cleaning system included in the above technical solution enables the self-cleaning function of the filter components, reduces the number of cleaning cycles, and also lowers the replacement cost of the filter components.

[0029] In one embodiment of the cleaning system of this utility model, the base station includes a blower generator, and the blower generator includes an air outlet that can communicate with a first vent.

[0030] In the above technical solution, by installing a blower generator in the base station, air can be blown into the dust box through the first vent and air inlet. On the one hand, this can blow the dust adhering to the filter assembly into the first chamber, thereby achieving self-cleaning of the filter assembly. On the other hand, it can blow the dust in the first chamber into an external dust collection device, thereby achieving self-cleaning of the dust box.

[0031] This invention relates to a dustbin that divides its body into a first chamber and a second chamber via a filter assembly. The first chamber has an openable / closable suction port on its wall, and the second chamber has an openable / closable exhaust port on its wall. When the suction port and exhaust port are opened, the suction port, the first chamber, the second chamber, and the exhaust port form a suction channel. This allows airflow to draw dust into the suction port and retain it in the first chamber via the filter assembly. Simultaneously, clean air, filtered by the filter assembly, enters the second chamber through the pores and exits through the exhaust port. Furthermore, the second chamber has an openable / closable blowing port on its wall, and the first chamber has an openable / closable dust discharge port on its wall. When the blowing port and dust discharge port are opened, the blowing port, the second chamber, the first chamber, and the dust discharge port form a dust discharge channel. Airflow is blown into the second chamber through the air outlet, and then through the pores of the filter assembly into the first chamber. This blows dust and debris adhering to the pores and the side of the filter assembly facing the first chamber into the first chamber, where it is then discharged through the dust outlet located in the first chamber. This design achieves a self-cleaning function for the filter assembly, reducing the frequency of cleaning and lowering the replacement cost of the filter assembly. Attached Figure Description

[0050] Please see Figures 1 to 12 This utility model provides a dust box 100, a dust collection device 10, a cleaning device 1, and a cleaning system. The dust box 100 has a body 110 divided into a first chamber 130 and a second chamber 140 by a filter assembly 120. An openable and closable air outlet 141 is provided on the wall of the second chamber 140, and an openable and closable dust exhaust port 132 is provided on the wall of the first chamber 130. In response to the opening of the air outlet 141 and the dust exhaust port 132, the air outlet 141, the second chamber 140, the first chamber 130, and the dust exhaust port 132 form a dust exhaust channel. When the airflow is blown into the second chamber 140 through the air outlet 141 and then enters the first chamber 130 through the pores of the filter assembly 120, it can blow the dust and debris attached to the pores and the side of the filter assembly 120 facing the first chamber 130 into the first chamber 130, thereby realizing the self-cleaning function of the filter assembly 120, reducing the number of cleaning times, and also reducing the replacement cost of the filter assembly 120.

[0051] Please see Figure 8 and Figure 10The dust box 100 involved in this utility model is installed on the cleaning device 1. The cleaning device 1 involved in this utility model can be a floor scrubber, a sweeper, a cleaning robot, etc., but is not limited to these. Taking a cleaning robot as an example, in order to perform its cleaning function, the cleaning device 1 at least includes a vacuuming device 10 for collecting and removing dust from the ground. Specifically, the vacuuming device 10 includes a dust box 100 and a suction generator 200 connected to the dust box 100. The suction generator 200 generates negative pressure by rotating at high speed, sucking the dust into the dust box 100. In order to improve the vacuuming efficiency, the dust is pre-collected. In some embodiments, the vacuuming device 10 is also equipped with cleaning components such as a roller brush.

[0052] In some embodiments, the cleaning device 1 further includes a wet cleaning apparatus for achieving wet cleaning, which includes a cleaning head, a liquid storage tank, a pump body, and piping components. In other embodiments, the cleaning device 1 also includes an intelligent control system, which can integrate various functions according to actual needs. These functions may include, but are not limited to, autonomous travel planning based on sensors such as accelerometers, gyroscopes, and odometers; obstacle recognition and collision avoidance based on devices such as distance sensors and image recognition devices; autonomous walking based on mechanical mechanisms such as drive wheel sets, driven wheel sets, and drivers; human-computer interaction based on devices such as physical buttons, virtual buttons, displays, and indicator lights; energy supply based on rechargeable batteries; and intelligent control based on control circuits or control chips, etc., which will not be elaborated on in detail.

[0053] Please see Figure 1 and Figure 2 In one example of the dustbin 100 involved in this utility model, the dustbin 100 includes a box body 110 and a filter assembly 120; the shape of the box body 110 is not limited, for example, it can be square, circular, polygonal or other irregular shapes. In this embodiment, the shape of the box body 110 is roughly a horizontally placed polygonal shape, which can be reasonably arranged with other components in the cleaning equipment 1 to achieve a high utilization rate in a limited space.

[0054] Please see Figure 1 and Figure 2The filter assembly 120 is installed inside the housing 110, dividing the inner cavity of the housing 110 into a first chamber 130 and a second chamber 140. The first chamber 130 and the second chamber 140 are connected through the pores of the filter assembly 120. The installation position of the filter assembly 120 is not limited; for example, it can be placed horizontally, vertically, or at an angle to the horizontal. When the filter assembly 120 is placed horizontally, the first chamber 130 and the second chamber 140 are arranged vertically; when the filter assembly 120 is placed vertically, the first chamber 130 and the second chamber 140 are arranged front-to-back; when the filter assembly 120 is placed at an angle to the horizontal, the first chamber 130 and the second chamber 140 are arranged at an angle. The filter assembly 120 can be installed in various ways, including but not limited to threaded connections, snap-fit ​​connections, or plug-in connections, as long as they can isolate the first chamber 130 and the second chamber 140, be fixed inside the housing 110, and provide a seal at the connection point with the housing 110.

[0055] Please see Figure 1 and Figure 2 In this embodiment, the filter assembly 120 includes a filter element 121 and a filter element mounting base 122, with the filter element 121 detachably mounted on the filter element mounting base 122. Making the filter element 121 detachable facilitates cleaning and replacement, especially when replacement is required; only the filter element 121 needs to be replaced, without replacing the entire filter assembly 120. Furthermore, this design allows for adaptable design of the filter element mounting base 122, reducing design and manufacturing complexity to accommodate the space within the housing 110 and the shape of the filter element 121. The filter element 121 can be made of various materials, including but not limited to HEPA (High Efficiency Particulate Air) filters, activated carbon filters, polyester fiber filters, or nylon fiber filters. A surrounding mounting plate 123 is connected to the inner wall of the first chamber 130 and / or the inner wall of the second chamber 140, and the filter element mounting base 122 is sealed to the mounting plate 123. The mounting plate 123 facilitates the fixation of the filter element mounting base 122. The sealed connection between the filter element mounting base 122 and the mounting plate 123 reduces the possibility of dust entering the second chamber 140 from the installation gap, which helps to improve the filtration efficiency of the filter assembly 120.

[0056] To enable the dust collection function of filter assembly 120, please refer to... Figure 1 , Figure 2 and Figure 9The first chamber 130 has an openable and closable dust suction port 131 and an openable and closable dust exhaust port 132 on its wall, and the second chamber 140 has an openable and closable air blowing port 141 and an openable and closable air extraction port 142 on its wall. The location of the dust suction port 131, dust exhaust port 132, air blowing port 141 and air extraction port 142 is not limited. For example, the dust suction port 131 and dust exhaust port 132 can be located on the side wall or bottom wall of the first chamber 130, and the air blowing port 141 and air extraction port 142 can be located on the side wall or bottom wall of the second chamber 140. It should be noted that in some embodiments, the openability of the suction port 131, the exhaust port 132, the blowing port 141, and the exhaust port 142 is controlled by an openable and closable structure. This structure can be located on the inner or outer side of the wall at the opening of the suction port 131, the exhaust port 132, the blowing port 141, and the exhaust port 142, as well as other locations where opening and closing can be controlled. For example, an openable and closable first baffle 134 is provided on the inner side of the wall at the opening of the suction port 131; an openable and closable second baffle 135 is provided on the outer side of the wall at the opening of the exhaust port 132; an air inlet channel 150 is provided between the blowing port 141 and the outer surface of the cleaning device 1, and an openable and closable baffle 151 is provided within the air inlet channel 150; an openable and closable baffle is provided on the wall at the opening of the exhaust port 142, and other opening and closing structures are provided in the suction generator 200 connected thereto (not shown in the figures). The opening and closing of the opening and closing structures provided on the suction port 131, dust discharge port 132, air blowing port 141 and exhaust port 142 can be achieved by the action of high-pressure airflow provided by an external fan, electrical control or mechanical control, etc. The closing of the opening and closing structures provided on the suction port 131, dust discharge port 132, air blowing port 141 and exhaust port 142 can be achieved by gravity, spring return, electrical control or mechanical control, etc., and there is no limitation on this.

[0057] Please see Figure 1 , Figure 2 and Figure 9 The suction generator 200 draws air from the exhaust port 142, enabling dust to be sucked in from the suction port 131. At this time, the suction port 131, the first chamber 130, the second chamber 140, and the exhaust port 142 form a suction channel. Dust enters the first chamber 130 from the suction port 131, where the filter assembly 120 retains it. Simultaneously, clean air filtered by the filter assembly 120 enters the second chamber 140 through its pores and is discharged from the exhaust port 142, thus completing the suction operation. When the intelligent control system detects that the cleaning device 1 is performing suction, it controls the exhaust port 132 and the blower port 141 to close, which helps maintain the airtightness of the dust box 100, creating a high negative pressure within the dust box 100 to achieve efficient suction.

[0058] Please see Figure 1 , Figure 2 and Figure 9In one embodiment, the intelligent control system detects that the cleaning device 1 has stopped vacuuming and responds by opening the air outlet 141 and the dust outlet 132. At this time, the air outlet 141, the second chamber 140, the first chamber 130, and the dust outlet 132 form a dust removal channel. Specifically, when the air outlet 141 is opened, air is blown from the side of the air outlet 141 facing the filter assembly 120 towards the second chamber 140. When the airflow enters the first chamber 130 through the pores of the filter assembly 120, it blows the dust adhering to the pores and the side of the filter assembly 120 facing the first chamber 130 into the first chamber 130, thus cleaning the filter assembly 120. It should be noted that the airflow blown in from the air outlet 141 can be provided by connecting the air outlet 141 to a blower generator or by connecting the dust outlet 132 to a suction device; there is no limitation on this. The dust blown into the first chamber 130 is then discharged through the dust outlet 132 located in the first chamber 130. This design enables a self-cleaning function for the filter assembly 120, reducing the frequency of cleaning and lowering the replacement cost of the filter assembly 120. Furthermore, the airflow for cleaning the filter assembly 120 is directed from the back to the front of the filter assembly 120 for optimal cleaning results. It should be noted that the back and front of the filter assembly 120 are defined as follows: during cleaning, dust particles are drawn into the dust box 100 through the dust inlet, and the filter assembly 120 filters them. In this case, the filtering surface of the filter assembly 120 is the front, and the opposite surface is the back.

[0059] Please see Figures 7 to 9 In one embodiment of the dust box 100 of this utility model, the air inlet 141 is sealed to an air inlet channel 150, which connects the air inlet 141 and the outside of the cleaning device 1. The shape of the air inlet channel 150 is not limited, as long as it can achieve the connection between the air inlet 141 and the outside of the cleaning device 1. The sealed connection between the air inlet channel 150 and the air inlet 141 can be achieved by setting a silicone rubber sealing ring or a foam sealing ring, etc., around the connection between the air inlet channel 150 and the air inlet 141. In response to the opening of the air inlet 141 and the dust outlet 132, an airflow channel is formed between the air inlet channel 150 and the dust outlet 132. The airflow channel guides the airflow from the outside of the cleaning device 1 from the air inlet 141 to the filter assembly 120. Specifically, the airflow enters from the air inlet channel 150, then passes through the air inlet 141, the second chamber 140, the filter assembly 120 and the first chamber 130, and finally exits from the dust outlet 132. Airflow can blow dust and debris adhering to the pores and the side of the filter assembly 120 facing the first chamber 130 into the first chamber 130, thus cleaning the filter assembly 120. The air inlet channel 150 is designed to guide airflow from outside the cleaning device 1 into the dust box 100, facilitating airflow entry while minimizing impact on other components within the cleaning device 1.

[0060] Please see Figures 7 to 9 In one embodiment of the dust box 100 of this utility model, an openable and closable baffle 151 is provided inside the air inlet channel 150 to control the opening and closing of the air outlet 141. The shape of the baffle 151 is adapted to the inner wall of the air inlet channel 150 to achieve a better wind-blocking effect when the baffle 151 is closed. Depending on the different shapes of the air inlet channel 150, the baffle 151 can be opened by rotation, folding, or insertion, and there is no limitation thereto. In this embodiment, the baffle 151 and the air inlet channel 150 are rotatably connected by a rotating shaft. The baffle 151 is closed by rotating it to a position perpendicular to the air inlet channel 150, and opened by rotating it to a position parallel to the air inlet channel 150. There are various ways to drive the opening and closing of the baffle 151, which can be achieved by motor control or by setting elastic elements on the baffle 151 and the air inlet channel 150. It should be noted that in one embodiment where the baffle 151 is controlled by the elastic element, the baffle 151 can be in a normally closed state under the action of the elastic element. When the cleaning of the filter assembly 120 begins, the airflow acting on the baffle 151 can overcome the elastic force of the elastic element, causing the baffle 151 to open. When the cleaning of the filter assembly 120 ends, the baffle 151 returns to its closed state under the action of the elastic element. In order to achieve the baffle 151 closing during the dust collection process and opening during the cleaning of the filter assembly 120, the airflow of the suction generator 200 needs to be less than the resistance of the elastic element, while the airflow of the cleaning filter assembly 120 needs to be greater than the resistance of the elastic element. Setting the baffle 151 within the air inlet channel 150 provides ample installation space for the baffle 151, reducing the limitations imposed by the installation space on the structure driving the opening and closing of the baffle 151, increasing the selection space for the structural forms driving the opening and closing of the baffle 151, and thus reducing processing difficulty and production costs.

[0061] Please see Figures 7 to 8 In one embodiment of the dust box 100 of this utility model, a drive mechanism 152 is provided on the outer side of the air inlet channel 150. The drive mechanism 152 drives the baffle 151 to open or close, thereby controlling the opening and closing of the air outlet 141. The drive mechanism 152 can take many forms, such as motor drive, synchronous belt drive, gear drive, or electromagnetic drive, etc., and is not limited thereto. The drive mechanism 152 is located on the outer side of the air inlet channel 150, which allows the drive mechanism 152 to be installed inside the cleaning equipment 1, making full use of the internal space of the cleaning equipment 1, and also providing protection for the drive mechanism 152. In this embodiment, a motor drive is used, and the motor can be connected to an intelligent control system to realize the automated control of the opening or closing of the baffle 151 by the intelligent control system.

[0062] Please see Figures 1 to 2In one embodiment of the dust box 100 of this utility model, the upper end of the box body 110 has an opening 111, and an openable and closable lid 160 is connected to the opening 111. The first chamber 130 is located below the second chamber 140. By placing the opening 111 at the upper end of the box body 110 and connecting the openable and closable lid 160 to the opening 111, the lid 160 can be opened without removing the dust box 100, allowing the filter element 121 to be removed for cleaning or replacement. In addition, by placing the first chamber 130 below the second chamber 140, dust particles can automatically fall into the first chamber 130, which serves as a dust particle storage space, under their own weight, without the need for external force, and at the same time, the amount of dust particles adhering to the filter element 120 can be reduced. The second chamber 140 is positioned above the first chamber 130, so that the airflow entering from the air outlet 141 blows away the dust and debris attached to the filter assembly 120, allowing it to automatically fall into the first chamber 130 and preventing it from re-attaching to the filter assembly 120. It should be noted that the filter assembly 120 can be placed horizontally or at an angle of less than 45° to the horizontal, as long as the first chamber 130 is located below the second chamber 140.

[0063] Please see Figures 1 to 2 In one embodiment of the novel dustbin 100 disclosed herein, the wall of the first chamber 130 includes an inclined wall 133 that gradually slopes downwards into the first chamber 130. A suction port 131 is disposed on the inclined wall 133, and an openable first baffle 134 is installed on the inner side of the inclined wall 133, covering the suction port 131. This arrangement allows the first baffle 134 to close under its own weight when there is no external suction, preventing dust from flowing out of the suction port 131. Simultaneously, it can open by using external suction force to resist gravity for suction operations. This structure is simple in design, low in cost, and occupies little space.

[0064] Please see Figures 3 to 4 In one embodiment of the dustbin 100 of this utility model, at least one locking member 180 is provided on the outer periphery of the box body 110. The locking member 180 includes a connecting arm 181 and a protrusion 182 disposed on the connecting arm 181. Under the action of external force, the connecting arm 181 drives the protrusion 182 closer to the box body 110, and under its own elasticity, drives the protrusion 182 away from the box body 110, so as to be used for external locking. The setting of the locking member 180 can realize the fixation of the box body 110 inside the cleaning equipment 1. The cooperation between the connecting arm 181 and the protrusion 182 has the effects of ingenious structure, simple operation, and reliable locking.

[0065] Please see Figures 5 to 6In one embodiment of the dustbin 100 of this utility model, at least one limiting part 170 is provided on the outer periphery of the box body 110. The limiting part 170 includes a groove 171 recessed into the box body 110, which engages externally to limit the position of the box body 110. The limiting part 170 can limit the position of the dustbin 100, which on the one hand facilitates installation guidance and improves installation efficiency; on the other hand, the limiting part 170 in the form of a groove 171 can cooperate with external structural components to restrict multiple degrees of freedom of the dustbin 100, thereby improving the firmness and reliability of the dustbin 100 in the cleaning equipment 1.

[0066] Please see Figures 8 to 9 A second aspect of this utility model also provides a vacuuming device 10, which includes a suction generator 200 and a dust box 100 as described above. The suction generator 200 is connected to an exhaust port 142. It should be noted that the suction generator 200 can be installed in various locations, such as in the dust box 100 or other locations on the cleaning device 1, as long as it can communicate with the exhaust port 142. The suction generator 200 can be any structure capable of generating negative pressure, such as a combination of an axial fan, a motor, and spiral blades, etc., which will not be elaborated further here. The vacuuming device 10, including the dust box 100, achieves a self-cleaning function for the filter assembly 120, reducing the frequency of cleaning and lowering the replacement cost of the filter assembly 120.

[0067] Please see Figures 10 to 12 A third aspect of this utility model also provides a cleaning device 1, which includes a base 20 and the aforementioned vacuuming device 10. The base 20 is the main structural component of the cleaning device 1. The vacuuming device 10 and other functional components are detachably installed in the base 20, thereby enabling the base 20 to drive the cleaning components to move and simultaneously introduce a medium into the cleaning components to perform cleaning operations. In this embodiment, the base 20 has a mounting position 240, and the vacuuming device 10 is detachably installed in the mounting position 240. The mounting position 240 may be a recessed structure that is adapted to accommodate the vacuuming device 10. The limiting part 170 limits the dust box 100 and also limits the vacuuming device 10, and the locking member 180 locks and fixes the dust box 100 and also locks and fixes the vacuuming device 10. The cleaning device 1, including the vacuuming device 10, achieves a self-cleaning function for the filter assembly 120, reducing the number of cleaning cycles and lowering the replacement cost of the filter assembly 120.

[0068] Please see Figures 10 to 12In one embodiment of the cleaning device 1 of this utility model, the base 20 further includes a first vent 210, a second vent 220 disposed on the outer surface, and a third vent 230 disposed at the bottom of the base 20. The location of the first vent 210 is not limited; it can be disposed on the top wall or the bottom wall of the cleaning device 1, as long as it can communicate with the air outlet 141. By providing the first vent 210 on the outer surface of the cleaning device 1 and communicating with the air outlet 141, airflow is introduced into the dust box 100 for cleaning the filter assembly 120 by blowing air through it. The location of the second vent 220 is not limited; it can be disposed on the end wall or the bottom wall of the cleaning device 1, as long as it can communicate with the dust discharge port 132. By providing a second vent 220 on the outer surface of the cleaning device 1, which communicates with the dust outlet 132, the dust temporarily stored in the first chamber 130 is collected and moved to the outside of the cleaning device 1, thereby enabling the dust box 100 to self-clean. A third vent 230 is located at the bottom of the base 20 and communicates with the suction port 131, thus cleaning the contact surface with the bottom of the cleaning device 1.

[0069] A fourth aspect of this invention also provides a cleaning system (not shown in the figure), which includes the cleaning device 1 described above and a base station (not shown in the figure) adapted to the cleaning device 1. The cleaning system including the cleaning device 1 achieves a self-cleaning function for the filter assembly 120, reduces the number of cleaning cycles, and also reduces the replacement cost of the filter assembly 120.

[0070] In one embodiment of the cleaning system of this utility model, the base station includes a blower generator, which includes an air outlet that can communicate with the first vent 210. Air is blown into the dust box 100 through the first vent 210 and the air outlet 141. This serves two purposes: firstly, it blows the dust adhering to the filter assembly 120 into the first chamber 130, thereby achieving self-cleaning of the filter assembly 120; secondly, it blows the dust in the first chamber 130 into an external dust collection device, thereby achieving self-cleaning of the dust box 100. The blower generator can be any structure capable of generating high-pressure air, such as an air compressor or a blower, which will not be described in detail here.

[0071] In one embodiment of the cleaning system of this utility model, the base station includes a dust collection device, which includes a suction component and a dust collection bag. The suction device is connected to the dust discharge port 132 and can suck the dust collected in the dust box 100 into the dust collection bag. The suction airflow provided by the suction component can enter the second chamber 140 from the air outlet 141, which can also blow the dust attached to the filter component 120 into the first chamber 130, thereby achieving self-cleaning of the filter component 120.

[0072] The dustbin of this invention divides the box body into a first chamber and a second chamber through a filter assembly. An openable air outlet is provided on the wall of the second chamber. Airflow enters the second chamber through the air outlet, passes through the pores of the filter assembly, and then enters the first chamber. This blows dust adhering to the pores and the side of the filter assembly facing the first chamber into the first chamber, where it is then discharged through a dust outlet located in the first chamber. This design achieves a self-cleaning function for the filter assembly, reducing the frequency of cleaning and lowering the replacement cost of the filter assembly. Therefore, this invention effectively overcomes practical problems and has high utilization value and practical significance.

[0073] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
