Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, specifically to a dust box assembly, a dust collection device, a cleaning equipment, and a cleaning system. Background Technology

[0002] The working principle of a sweeper vacuuming machine involves using an electric motor to drive the blades to rotate at high speed, creating negative pressure in a sealed dust box, which sucks up dusty surfaces such as carpets and floors. The dust and debris are sucked into the filter along with the air, filtered by the filter elements in the filter and collected in the dust box, while the filtered clean air is expelled from the sweeper.

[0003] After a period of operation, a large amount of dust accumulates on the surface of the filter on the dust inlet side. This excessive dust buildup can clog the tiny pores of the filter, thus affecting its filtration capacity. Since some of the dust is not dry, bacteria and mold can easily grow on the filter in humid environments, producing unpleasant odors. If not cleaned and dried promptly, these bacteria, mold, and odors will pollute the air during subsequent use. Utility Model Content

[0004] This disclosure provides a dust box assembly, a dust collection device, a cleaning equipment, and a cleaning system to achieve self-cleaning and self-drying functions for filters, thereby improving the technical problem of bacteria and mold growth on filters.

[0005] To achieve the above and other related objectives, the first aspect of this disclosure provides a dust box assembly installed in a cleaning device, including a dust box, a filter, and a cleaning and drying air duct; the dust box is provided with an air inlet, an air suction port, and an air blowing port; the filter is installed inside the dust box, dividing the inner cavity of the dust box into a first chamber and a second chamber, the air inlet is located on the wall of the first chamber, and the air blowing port and air suction port are located on the wall of the second chamber; one end of the cleaning and drying air duct is connected to the second chamber through the air blowing port, and the other end is connected to the outside of the cleaning device, and the cleaning and drying air duct or the air blowing port is provided with an openable and closable baffle; in response to the opening of the baffle, the cleaning and drying air duct guides hot air into the second chamber to dry the filter.

[0006] In the above technical solution, a filter is installed in the dust box, dividing the dust box into a first chamber and a second chamber. The air inlet is located on the wall of the first chamber, while the blowing and suction ports are located on the wall of the second chamber. The filter is positioned between the air inlet and the suction port. When air is drawn in through the suction port, airflow draws in dust particles from the inlet, which are then trapped on the side of the filter closest to the inlet. The filtered clean air is then discharged through the suction port, completing the dust collection operation. By connecting a cleaning and drying duct to the outside of the dust box, airflow can be directed into the inner cavity of the dust box. Since the cleaning and drying duct connects to the second chamber through the blowing port, and the blowing port is located on the wall of the second chamber, the air entering through the blowing port can be blown from the cleaner side of the filter to the side with dust particles, effectively removing dust particles clogging the tiny filter pores and cleaning the filter.

[0007] In addition, the hot air guided into the second chamber by the cleaning and drying duct can dry the filter and dust box, thus also serving a certain function of cleaning the filter. This self-cleaning and self-drying process can be performed immediately after vacuuming, reducing the growth of bacteria and mold. It can also be timed or scheduled at regular intervals. Both the self-cleaning and self-drying processes effectively reduce the generation of bacteria, mold, and odors, minimizing environmental pollution. Furthermore, the self-cleaning and self-drying processes eliminate the need for manual filter cleaning or drying. This technology also extends the filter's lifespan, reduces the frequency of filter replacement, and lowers consumable replacement costs.

[0008] In one embodiment of the dust box assembly disclosed herein, an openable dust collection port is further provided on the wall of the first chamber. In response to the closing of the dust collection port and the opening of the baffle plate, a first airflow channel is formed between the cleaning and drying air duct and the dust collection port. The cleaning and drying air duct guides hot air from the outer self-blowing air outlet of the cleaning equipment through the first airflow channel to the filter to dry the filter.

[0009] In the above technical solution, the dust collection port is used to collect the dust temporarily stored in the dust box, and then discharge the dust from the dust box through the dust collection port. When the baffle plate is opened, a first airflow channel is formed between the cleaning and drying air duct and the dust collection port. The hot air entering through the air outlet dries the filter as it passes through this first airflow channel, and also cleans the filter. During this process, the dust collection port closes. This design allows the hot air to be concentrated inside the dust box, ensuring sufficient combination between the filter and the hot air, thereby improving drying efficiency.

[0010] In one embodiment of the dust box assembly disclosed herein, the wall of the first chamber is further provided with an openable dust collection port. In response to the opening of the dust collection port and the baffle plate, a second airflow channel is formed between the cleaning and drying air duct and the dust collection port. The cleaning and drying air duct guides the airflow from the outside of the cleaning equipment through the air blower to the filter via the second airflow channel, and then discharges through the dust collection port and the suction port.

[0011] In the above technical solution, the dust collection port and the baffle plate are opened at the same time, forming a second airflow channel between the cleaning and drying air duct and the dust collection port. The airflow entering through the air outlet cleans the filter as it passes through the second airflow channel. At the same time, because the dust collection port is open, the airflow in the second airflow channel can discharge the dust temporarily stored in the dust box through the dust collection port, thus realizing the two functions of self-cleaning filter and dust collection.

[0012] In one embodiment of the dust box assembly disclosed herein, the cleaning and drying air duct is detachably connected to the cleaning equipment via a first plug-in structure and is in sealed communication with the dust box.

[0013] In the above technical solution, the cleaning and drying air duct adopts the first plug-in structure for installation, which can achieve the effect of quick assembly and disassembly, and has the advantages of compact structure and reliable connection.

[0014] In one embodiment of the dust box assembly disclosed herein, a second plug-in structure for detachably plugging into a cleaning device is further provided on the outer wall of the cleaning and drying air duct. The second plug-in structure is spaced apart from the first plug-in structure along the extension direction of the cleaning and drying air duct and is consistent with the disassembly and assembly direction of the first plug-in structure.

[0015] In the above technical solution, a second plug-in structure is added on the basis of the first plug-in structure connection, and the second plug-in structure has a gap with the first plug-in structure, which can realize multiple connection positions between the cleaning and drying air duct and the cleaning equipment, thereby improving the reliability of the cleaning and drying air duct installation.

[0016] In one embodiment of the dust box assembly disclosed herein, a fixed connection structure for fixing to the cleaning equipment is further provided on the outer wall of the cleaning and drying air duct.

[0017] In the above technical solution, a fixed connection structure is used for further connection and fixation. Since hot air flows through the cleaning and drying duct, this causes temperature changes within the duct, and frequent thermal expansion and contraction can easily lead to loosening of the connections. By setting up a fixed connection structure, the problem of loosening caused by thermal expansion and contraction can be effectively alleviated.

[0018] In one embodiment of the dust box assembly disclosed herein, a flow guiding structure is provided on the connecting channel between the cleaning and drying air duct and the air outlet.

[0019] In the above technical solution, the flow-guiding structure guides the airflow to be distributed according to its shape, ensuring uniform distribution of hot air onto the filter. Furthermore, the cross-sectional area through which the airflow passes decreases as it passes the flow-guiding structure; according to the continuity equation, a smaller cross-sectional area results in an increased airflow velocity. In summary, the flow-guiding structure guides the airflow to be evenly distributed and increases its velocity, thereby improving the efficiency and quality of self-cleaning and drying.

[0020] A second aspect of this disclosure also provides a vacuuming device including a suction generator and a dust box assembly of any of the above, the suction generator being connected to an air intake.

[0021] In the above technical solution, the dust collection device including the dust box assembly realizes the self-cleaning function of the filter, reduces the number of cleaning times, and also reduces the replacement cost of the filter.

[0022] A third aspect of this disclosure also provides a cleaning device comprising a substrate and the aforementioned dust collection device, the substrate having a mounting position, the dust collection device being detachably mounted in the mounting position, and a cleaning and drying air duct being mounted in the substrate.

[0023] The above technical solution includes a cleaning device that enables self-cleaning and self-drying of the filter. These processes can be performed immediately after vacuuming, reducing the growth of bacteria and mold. Alternatively, cleaning and drying can be performed at set intervals. Both self-cleaning and self-drying processes effectively reduce the generation of bacteria, mold, and odors, thus minimizing environmental pollution. They also reduce the frequency of filter cleaning and lower filter replacement costs.

[0024] In one embodiment of the cleaning device disclosed herein, the substrate further includes a first vent, a second vent, and a third vent disposed on the outer surface of the substrate. The first vent is connected to an air blower, the second vent is connected to a dust collection port, and the third vent is connected to an air inlet.

[0025] In the above technical solution, by setting a first vent on the outer surface of the cleaning equipment and communicating with the air outlet, airflow is introduced into the dust box to clean the filter. By setting a second vent on the outer surface of the cleaning equipment and communicating with the dust collection port, the dust temporarily stored in the first chamber is collected outside the cleaning equipment, thus self-cleaning the dust box. By setting a third vent at the bottom of the cleaning equipment and communicating with the air inlet, the surface in contact with the bottom of the cleaning equipment is cleaned.

[0026] A fourth aspect of this disclosure also provides a cleaning system comprising the cleaning equipment described above and a base station adapted to the cleaning equipment.

[0027] The aforementioned technical solution includes a cleaning system that enables self-cleaning and self-drying of the filter, reducing the frequency of cleaning and lowering filter replacement costs. It effectively reduces the generation of bacteria, mold, and odors, thus minimizing environmental pollution.

[0028] In one embodiment of the cleaning system disclosed herein, the base station includes a blower generator and a drying device, the drying device being used to heat the gas generated by the blower generator, the blower generator including an air outlet capable of communicating with a first vent.

[0029] In the above technical solution, by installing a blower generator at the base station, air can be blown into the dust box through the first vent and air inlet. This serves two purposes: firstly, it blows the dust adhering to the filter into the first chamber, achieving self-cleaning of the filter; secondly, it blows the dust from the first chamber into an external dust collection device, achieving self-cleaning of the dust box. By installing a drying device at the base station, the air generated by the blower generator can be heated to dry the filter. The self-cleaning and self-drying processes can be performed promptly after dust collection, reducing the growth of bacteria and mold. Alternatively, cleaning and drying can be performed periodically or at set intervals. Both self-cleaning and self-drying processes effectively reduce the generation of bacteria, mold, and odors, reducing environmental pollution. They also reduce the frequency of filter cleaning and lower filter replacement costs.

[0030] The dustbin assembly disclosed herein includes a filter that divides the dustbin into a first chamber and a second chamber. An air inlet is located on the wall of the first chamber, while an air outlet and a suction inlet are located on the wall of the second chamber. The filter is positioned between the air inlet and the suction inlet. When air is drawn in through the suction inlet, airflow draws in dust particles, which are then trapped on the side of the filter closest to the air inlet. The filtered, clean air is then discharged through the suction inlet, completing the dust collection process. A cleaning and drying duct is connected to the outside of the dustbin, allowing airflow to be directed into the inner cavity of the dustbin. Since the cleaning and drying duct connects to the second chamber via the air outlet, which is located on the wall of the second chamber, air entering through the air outlet can be blown from the cleaner side of the filter towards the side containing dust particles. This effectively removes dust particles clogging the tiny filter pores, cleaning the filter.

[0031] In addition, the hot air guided into the second chamber by the cleaning and drying duct can dry the filter and dust box, thus also serving a certain function of cleaning the filter. This self-cleaning and self-drying process can be performed immediately after vacuuming, reducing the growth of bacteria and mold. It can also be timed or scheduled at regular intervals. Both the self-cleaning and self-drying processes effectively reduce the generation of bacteria, mold, and odors, minimizing environmental pollution. Furthermore, the self-cleaning and self-drying processes eliminate the need for manual filter cleaning or drying. This technology also extends the filter's lifespan, reduces the frequency of filter replacement, and lowers consumable replacement costs. Attached Figure Description

[0048] Please see Figures 1 to 10 This disclosure provides a dustbin assembly 100, a vacuuming device 10, a cleaning device 1, and a cleaning system. The dustbin assembly 100 includes a dustbin 110, a filter 120, and a cleaning and drying air duct 150. The dustbin 110 is divided into a first chamber 130 and a second chamber 140 by the filter 120. One end of the cleaning and drying air duct 150 is connected to the second chamber 140 through an air outlet 141, and the other end is connected to the outside of the cleaning device 1. The cleaning and drying air duct 150 can introduce hot air into the second chamber 140 of the dustbin 110 through the air outlet 141. Therefore, the air entering from the air outlet 141 can blow from the cleaner side of the filter 120 to the side with dust, which can remove the dust clogging the tiny filter pores of the filter 120 and clean the filter 120. In addition, the hot air guided into the second chamber 140 by the cleaning and drying air duct 150 can dry the filter 120 and the dustbin 110, and also has a certain function of cleaning the filter 120. The self-cleaning and self-drying process can be performed immediately after vacuuming, at set times, or at regular intervals, thereby effectively reducing the generation of bacteria, mold, and odors and minimizing environmental pollution.

[0049] Please see Figure 7 and Figure 10 The dustbin assembly 100 disclosed herein is installed in the cleaning device 1. The cleaning device 1 may be a cleaning robot, including floor scrubbers, sweepers, and other cleaning robots, but is not limited to these. Taking a cleaning robot as an example, to perform its cleaning function, the cleaning device 1 at least includes a vacuuming device 10 for collecting and removing dust from the ground. The vacuuming device 10 includes the dustbin assembly 100 and a suction generator 200 connected to the dustbin assembly 100. The suction generator 200 generates negative pressure through high-speed rotation, sucking dust into the dustbin assembly 100. To improve vacuuming efficiency and pre-collect dust, in some embodiments, the vacuuming device 10 is also equipped with cleaning components such as a roller brush.

[0050] 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 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 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.

[0051] Please see Figures 1 to 2 In one example of the dustbin assembly 100 disclosed herein, the dustbin assembly 100 is installed in a cleaning device 1 and includes a dustbin 110, a filter 120, and a cleaning and drying air duct 150. The shape of the dustbin 110 is not limited; for example, it can be square, circular, polygonal, or other irregular shapes. In this embodiment, the dustbin 110 is approximately a horizontally placed polygonal shape. This arrangement allows for reasonable arrangement with other components in the cleaning device 1, achieving high utilization within a limited space.

[0052] Please see Figures 1 to 2 The filter 120 is installed inside the dust box 110, dividing the inner cavity of the dust box 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 120. The installation position of the filter 120 is not limited; for example, it can be placed horizontally, vertically, or at a certain angle to the horizontal direction. When the filter 120 is placed horizontally, the first chamber 130 and the second chamber 140 are arranged vertically; when the filter 120 is placed vertically, the first chamber 130 and the second chamber 140 are arranged front to back; when the filter 120 is placed at a certain angle to the horizontal direction, the first chamber 130 and the second chamber 140 are arranged at a certain angle. There are various installation methods for the filter 120, including but not limited to threaded connection, snap-fit, or plug-in connection, as long as it can isolate the first chamber 130 and the second chamber 140, fix them inside the dust box 110, and seal the connection with the dust box 110.

[0053] Please see Figures 1 to 2In this embodiment, the filter 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 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 dust box 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.

[0054] Please see Figures 1 to 3 The dust box 110 is equipped with an air inlet 131, an air intake 142, and an air outlet 142. The air inlet 131 is located on the wall of the first chamber 130, while the air outlet 141 and air intake 142 are located on the wall of the second chamber 140. The locations of the air inlet 131, air intake 141, and air intake 142 are not limited; for example, the air inlet 131 can be located on the side wall or bottom wall of the first chamber 130, and the air outlet 141 and air intake 142 can be located on the side wall or bottom wall of the second chamber 140. It should be noted that the air inlet 131, air intake 141, and air intake 142 are all openable and closable, and different working tasks can be achieved by controlling their opening and closing. In some embodiments, the openability of the air inlet 131, the blowing port 141, and the suction 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 air inlet 131, the blowing port 141, and the suction port 142, or at other locations where opening and closing can be controlled. For example, an openable and closable first baffle 133 can be provided on the inner side of the wall at the opening of the air inlet 131; an openable and closable baffle can be provided on the wall at the opening of the suction port 142. The opening of the opening and closing structures on the air inlet 131, the blowing port 141, and the suction port 142 can be achieved by the action of high-pressure airflow provided by an external fan, electrical control, or mechanical control. The closing of the opening and closing structures on the air inlet 131, the blowing port 141, and the suction port 142 can be achieved by gravity, spring return, electrical control, or mechanical control, and is not limited thereto.

[0055] Please see Figure 2The suction generator 200 draws air from the suction port 142, which in turn draws dust and debris from the air inlet 131. At this time, the air inlet 131, the first chamber 130, the second chamber 140, and the suction port 142 form a dust collection channel. Dust and debris enter the first chamber 130 from the air inlet 131, and the filter 120 retains the dust and debris in the first chamber 130. At the same time, the clean air filtered by the filter 120 enters the second chamber 140 through the pores and is discharged from the suction port 142, thus realizing the dust collection work.

[0056] Please see Figures 1 to 2 The dust box assembly 100 also includes a cleaning and drying air duct 150. One end of the cleaning and drying air duct 150 is connected to the second chamber 140 via an air outlet 141, and the other end is connected to the outside of the cleaning device 1. The installation position of the cleaning and drying air duct 150 is not limited; it can be directly connected to the dust box 110 or connected to other components, as long as it enables one end of the cleaning and drying air duct 150 to connect to the second chamber 140 via the air outlet 141. An openable and closable baffle 151 is provided on the cleaning and drying air duct 150 or the air outlet 141. The installation position of the baffle 151 is not limited; for example, it can be installed inside the cleaning and drying air duct 150 or on the air outlet 141. The material of the baffle 151 is not limited and can be plastic, metal, or soft rubber, etc. In this embodiment, the baffle 151 is made of soft rubber, such as silicone or rubber, because soft rubber is elastic and can better fit the mating surface to form a good sealing effect. This helps maintain the airtightness of the dust box 110, resulting in a high negative pressure in the dust box 110 to achieve a high-efficiency dust collection effect. Soft rubber also has high heat resistance and anti-aging properties, allowing it to be used for a long time in high-temperature environments without easily aging or becoming brittle, thus improving the service life of the baffle 151. The opening of the baffle 151 can be achieved by the high-pressure airflow provided by an external fan, electrical control, or mechanical control. The closing of the baffle 151 can be achieved by its own weight, spring return, electrical control, or mechanical control, etc., and is not limited in this respect.

[0057] Please see Figure 2In one embodiment, in response to the opening of the baffle plate 151, the air outlet 141 opens, forming a cleaning channel with the air outlet 141, the second chamber 140, and the first chamber 130. Airflow enters from the air outlet 141 on the side of the filter 120 facing the second chamber 140. When the airflow passes through the pores of the filter 120 and enters the first chamber 130, it blows dust adhering to the pores and the side of the filter 120 facing the first chamber 130 into the first chamber 130, thus completing the self-cleaning filter 120's operation. Furthermore, the airflow cleaning the filter 120 blows from the back of the filter 120 to the front, i.e., from the cleaner side of the filter 120 to the side with dust, achieving the best cleaning effect. It should be noted that the back and front of the filter 120 are defined as follows: during cleaning, dust is drawn into the dust box 110 through the air inlet 131, and the filter 120 filters it. At this time, the filtering surface of the filter 120 is the front, and the opposite side is the back. In addition, the airflow entering from the air outlet 141 can be provided by connecting the air outlet 141 to a blower generator, or it can be provided by connecting a suction device to the wall of the first chamber 130, and there is no limitation on this.

[0058] Please see Figures 1 to 2 A device capable of heating the airflow is installed inside or outside the cleaning equipment 1 to heat the airflow entering the cleaning channel into hot air. The cleaning and drying air duct 150 guides the hot air into the second chamber 140, and then through the pores of the filter 120 into the first chamber 130. This process can dry the filter 120 itself, dry the dust box 110, and also have a certain function of cleaning the filter 120.

[0059] Considering that dust particles in a non-dry state will adhere to the filter 120 after vacuuming, if it is accumulated after several vacuuming sessions before cleaning and drying, instead of being cleaned and dried promptly, bacteria and mold can easily grow on the filter 120 in a humid environment, producing odors. Manual cleaning and drying immediately after each vacuuming session would increase the workload. In one embodiment, the self-cleaning and self-drying process can be performed immediately after vacuuming. Timely cleaning and drying reduces the growth of bacteria and mold, replacing manual cleaning and drying and reducing workload. In other embodiments, cleaning and drying can also be performed at set times, such as at a certain time each day. In other embodiments, it can be set to occur at regular intervals, which can be the interval between cleaning and drying and vacuuming operations, or the interval between multiple cleaning and drying operations. All of the above self-cleaning and self-drying processes can effectively reduce the generation of bacteria, mold, and odors, reducing environmental pollution. Moreover, the self-cleaning and self-drying process eliminates the need for disassembly and manual cleaning or drying of the filter 120. This technical solution can also improve the service life of filter 120, reduce the frequency of replacing filter 120, and reduce the replacement cost of consumables.

[0060] Please see Figures 1 to 2 In one embodiment of the dust box assembly 100 disclosed herein, an openable dust collection port 132 is further provided on the wall of the first chamber 130. The dust collection port 132 is provided to collect dust temporarily stored in the dust box 110, that is, to discharge the dust from the dust box 110 through the dust collection port 132. The dust collection port 132 is also openable and closable, and an openable and closable second baffle 134 is provided on the outer side of the wall at the opening of the dust collection port 132. The opening of the second baffle 134 can be achieved by the action of high-pressure airflow provided by an external fan, electrical control, or mechanical control, etc., and the closing of the second baffle 134 can be achieved by its own weight, spring return, electrical control, or mechanical control, etc., without limitation. In response to the closure of the dust collection port 132 and the opening of the baffle plate 151, a first airflow channel is formed between the cleaning and drying air duct 150 and the dust collection port 132. The cleaning and drying air duct 150 guides hot air from the outer air outlet 141 of the cleaning device 1 through the first airflow channel to the filter 120 to dry the filter 120. During this process, the dust collection port 132 is closed. This arrangement can concentrate the hot air in the dust box 110, so that the filter 120 is fully combined with the hot air, thereby improving the drying efficiency.

[0061] Please see Figures 1 to 2In one embodiment of the dust box assembly 100 of this disclosure, in response to the opening of the dust collection port 132 and the baffle plate 151, a second airflow channel is formed between the cleaning and drying air duct 150 and the dust collection port 132. The cleaning and drying air duct 150 guides airflow from the outside of the cleaning device 1 through the air blower 141 to the filter 120 via the second airflow channel, and then discharges through the dust collection port 132 and the suction port 142. The airflow entering through the air blower 141 cleans the filter 120 as it passes through the second airflow channel. At the same time, since the dust collection port 132 is open, the airflow in the second airflow channel can discharge the dust temporarily stored in the dust box 110 through the dust collection port 132, thus realizing both the self-cleaning filter 120 and the dust collection function. Additionally, with the dust collection port 132 and the baffle plate 151 open, airflow flows outward through the dust collection port 132 and the suction port 142. Simultaneously, the airflow flows through the cleaning and drying air duct 150, the blowing port 141, and the baffle plate 151 towards the dust box 110, creating a push-pull trend, which helps improve the efficiency of the self-cleaning filter 120 and the dust collection efficiency. It should be noted that the airflow through the second airflow channel can be provided by a blower generator connected to the blowing port 141. It can also be provided by a suction device connected to the dust collection port 132. Natural wind can also be used. The blower generator and the suction device can operate simultaneously, individually, or neither can operate, relying solely on natural wind; there are no limitations on this.

[0062] Please see Figures 4 to 6 In one embodiment of the dust box assembly 100 disclosed herein, the cleaning and drying air duct 150 is detachably connected to the cleaning device 1 via a first plug-in structure 152 and is in sealed communication with the dust box 110. Connecting the cleaning and drying air duct 150 to the cleaning device 1 facilitates the removal of the dust box 110 from the cleaning device 1 compared to connecting it directly to the dust box 110. In this embodiment, the cleaning device 1 includes a dust box receiving cavity 250 for placing the dust box 110, and the first plug-in structure 152 is connected to the wall of the dust box receiving cavity 250. The first plug-in structure 152 can be of various types and is not limited thereto. For example, it can be a snap-fit ​​type, tenon and mortise type, dovetail type, T-type type, or slide rail type. In this embodiment, a slide rail type is used. The first plug-in structure 152 includes two first grooves 1521 oppositely disposed on the wall of the dust box receiving cavity 250 and two first protrusions 1522 respectively oppositely disposed on both sides of the cleaning and drying air duct 150. The first protrusions 1522 and the first grooves 1521 are adapted to each other. The cleaning and drying air duct 150 is installed using the first plug-in structure 152, which can achieve the effect of quick assembly and disassembly, and has the advantages of compact structure and reliable connection. In this embodiment, the two first protrusions 1522 are respectively disposed on both sides of the cleaning and drying air duct 150 near the air outlet 141. This arrangement can facilitate the design of sealing rings or sealing strips between the cleaning and drying air duct 150 and the air outlet 141 to achieve good waterproof and sealing effects.

[0063] Please see Figures 4 to 6 In one embodiment of the dust box assembly 100 disclosed herein, a second insertion structure 153 for detachable insertion with the cleaning equipment 1 is further provided on the outer wall of the cleaning and drying air duct 150. The second insertion structure 153 can be of various types and is not limited thereto; for example, it can be a snap-fit ​​type, tenon and mortise type, dovetail type, T-type type, or slide rail type. The second insertion structure 153 and the first insertion structure 152 are spaced apart along the extension direction of the cleaning and drying air duct 150. This arrangement allows for multiple connection points between the cleaning and drying air duct 150 and the cleaning equipment 1, thereby improving the reliability of the installation of the cleaning and drying air duct 150. Furthermore, the second insertion structure 153 and the first insertion structure 152 are installed and removed in the same direction, which facilitates the synchronous installation of the second insertion structure 153 and the first insertion structure 152. In this embodiment, the second insertion structure 153 includes a second protrusion 1532 disposed on the cleaning device 1 and a second groove 1531 disposed on the cleaning and drying duct. The first protrusion 1522 of the first insertion structure 152 and the second groove 1531 of the second insertion structure 153 are disposed on the cleaning and drying duct 150. The arrangement of one protrusion and one groove can compensate for the influence of the sudden temperature changes in the cleaning and drying duct 150 on the first insertion structure 152 and the second insertion structure 153, and has a better anti-loosening effect.

[0064] Please see Figures 4 to 6 In one embodiment of the dust box assembly 100 disclosed herein, a fixing connection structure 154 for fixing to the cleaning equipment 1 is further provided on the outer wall of the cleaning and drying air duct 150. The type of fixing structure can be various and is not limited thereto; for example, it can be a threaded connection, riveted connection, adhesive connection, or interference fit. In this embodiment, the first plug-in structure 152 can also serve as a pre-connection between the cleaning and drying air duct 150 and the cleaning equipment 1, assisting or replacing manual handling to facilitate the subsequent installation of the fixing connection structure 154, improving installation efficiency and quality. The cleaning and drying air duct 150 and the cleaning equipment 1 are further connected and fixed using the fixing connection structure 154. Since hot air flows through the cleaning and drying air duct 150, this causes temperature changes in the duct, and frequent thermal expansion and contraction can easily lead to loosening of the connection. By providing the fixing connection structure 154, the problem of loosening caused by thermal expansion and contraction can be effectively alleviated.

[0065] Please see Figures 5 to 6In one embodiment of the dust box assembly 100 of this disclosure, a flow guiding structure 160 is provided on the connecting channel between the cleaning and drying air duct 150 and the air outlet 141. The installation position of the flow guiding structure 160 is not limited; it can be installed on the cleaning and drying air duct 150, the air outlet 141, or the cleaning device 1. In this embodiment, the flow guiding structure 160 between the dust box 110 and the cleaning and drying air duct 150 is installed on the wall of the dust box receiving cavity 250. The shape of the flow guiding structure 160 is not limited; for example, it can be multiple parallel strip holes, a honeycomb structure, or other structures that can achieve uniform flow guidance. In this embodiment, the flow guiding structure 160 is multiple parallel strip holes. The arrangement of the flow guiding structure 160 can guide the airflow to be distributed according to the shape of the flow guiding structure 160, so that the hot air is evenly distributed on the filter 120. Furthermore, when the airflow passes through the flow guiding structure 160, the cross-sectional area through which the airflow passes decreases. According to the continuity equation, a decrease in cross-sectional area leads to an increase in the airflow velocity through the cross-section. In summary, the airflow guiding structure 160 can guide the airflow to be evenly distributed and increase the airflow speed, thereby improving the efficiency and quality of self-cleaning and drying.

[0066] Please see Figure 2 In one embodiment of the dustbin assembly 100 of this disclosure, a drive mechanism is connected to the baffle 151, which controls the opening and closing of the baffle 151. The drive mechanism can take many forms, such as motor drive, synchronous belt drive, gear drive, or electromagnetic drive, and is not limited thereto. The drive mechanism is located outside the air inlet channel, allowing it 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. In this embodiment, a motor (not shown in the figure) is used for drive, and the motor can be connected to an intelligent control system to achieve automated control of the opening and closing of the baffle 151 by the intelligent control system.

[0067] Please see Figures 4 to 6 In one embodiment of the dustbin assembly 100 of this disclosure, the cross-sectional area of ​​the cleaning and drying duct 150 gradually decreases and then gradually increases along the direction of airflow within the cleaning and drying duct 150. The gradual decrease in cross-sectional area of ​​the cleaning and drying duct 150 allows for a gradual increase in the airflow velocity along the duct, while reducing the airflow pressure. The subsequent gradual increase in cross-sectional area allows for a rebound in airflow pressure, at which point the airflow velocity is further increased by the guide structure 160. Through this process, the airflow velocity within the cleaning and drying duct 150 can be increased with minimal airflow pressure loss, thereby further improving the efficiency and quality of cleaning and drying.

[0068] Please see Figures 4 to 6In one embodiment of the dust box assembly 100 disclosed herein, a heat insulation layer is provided on the wall of the cleaning and drying air duct 150. The heat insulation layer can be disposed on the inner wall, outer wall, or within a sandwich structure of the cleaning and drying air duct 150, and is not limited thereto. The material of the heat insulation layer can be ceramic fiber or aerogel, etc. The heat insulation layer reduces heat loss and energy consumption. Furthermore, it mitigates the thermal impact of heat on other adjacent components.

[0069] Please see Figures 4 to 6 In one embodiment of the dustbin assembly 100 disclosed herein, the inner wall of the cleaning and drying air duct 150 has a smooth transition. The smooth inner wall of the cleaning and drying air duct 150, i.e., the rounded corners, reduces air resistance and improves cleaning and drying efficiency.

[0070] Please see Figure 7 A second aspect of this disclosure also provides a vacuuming device 10, which includes a suction generator 200 and a dustbin assembly 100 as described above. The suction generator 200 is connected to the air intake 142. It should be noted that the suction generator 200 can be installed in various locations, such as in the dustbin 110 or other locations on the cleaning device 1, as long as it can communicate with the air intake 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 dustbin assembly 100, achieves a self-cleaning function for the filter 120, reducing the frequency of cleaning and lowering the replacement cost of the filter 120.

In this embodiment, the base 20 has a mounting position 240, to which the vacuuming device 10 is detachably installed. The mounting position 240 may be a recessed structure adapted to accommodate the vacuuming device 10. The cleaning device 1, including the vacuuming device 10, achieves self-cleaning and self-drying functions for the filter 120. The self-cleaning and self-drying processes can be performed promptly after vacuuming, reducing bacterial and mold growth. Cleaning and drying can also be performed periodically or at set intervals. Both self-cleaning and self-drying processes effectively reduce the generation of bacteria, mold, and odors, thus reducing environmental pollution. It can also reduce the number of times filter 120 needs to be cleaned, and reduce the replacement cost of filter 120.

[0072] Please see Figures 8 to 10 In one embodiment of the cleaning device 1 disclosed herein, the base 20 further includes a first vent 210, a second vent 220 disposed on its outer surface, and a third vent 230 disposed at the bottom of the base 20. The first vent 210 is connected to the air blower 141, the second vent 220 is connected to the dust collection port 132, and the third vent 230 is connected to the air inlet 131. The position 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 connect with the air blower 141. By providing the first vent 210 connected to the air blower 141 on the outer surface of the cleaning device 1, airflow is introduced into the dust box 110 for cleaning the filter 120 by blowing air through it. In addition, the hot air guided into the second chamber 140 by the cleaning and drying air duct 150 can dry the filter 120 and the dust box 110, and also has a certain function of cleaning the filter 120. The location of the second vent 220 is not limited; it can be located on either the end wall or the bottom wall of the cleaning device 1, as long as it allows communication between the second vent 220 and the dust collection port 132. By providing the second vent 220, which communicates with the dust collection port 132, on the outer surface of the cleaning device 1, the dust temporarily stored in the first chamber 130 is collected and moved to the outside of the cleaning device 1, thus enabling self-cleaning and self-drying of the dust box 110. The third vent 230 is located at the bottom of the base 20 and communicates with the air inlet 131, thus cleaning the contact surface with the bottom of the cleaning device 1.

[0073] A fourth aspect of this disclosure also provides a cleaning system (not shown in the figures) comprising the cleaning device 1 described above and a base station (not shown in the figures) adapted to the cleaning device 1. The cleaning system including the cleaning device 1 achieves self-cleaning and self-drying functions for the filter 120, reducing the frequency of cleaning and lowering the replacement cost of the filter 120. It can also effectively reduce the generation of bacteria, mold, and odors, thus reducing environmental pollution.

[0074] In one embodiment of the cleaning system disclosed herein, the base station includes a blower generator and a drying device. The drying device is used to heat the gas generated by the blower generator. The blower generator includes an air outlet that can communicate with the first vent 210. 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. By setting the blower generator in the base station, air can be blown into the dust box 110 through the first vent 210 and the air inlet 131. On the one hand, it can blow the dust attached to the filter 120 into the first chamber 130 to achieve self-cleaning of the filter 120. On the other hand, it can blow the dust in the first chamber 130 into an external dust collection device to achieve self-cleaning of the dust box 110. The drying device can be a device capable of heating air, such as resistance wire heating, infrared heating, or hot air circulation. By setting the drying device in the base station, the gas generated by the blower generator can be heated to achieve the drying function of the filter 120. The self-cleaning and self-drying processes can be performed immediately after vacuuming, reducing the growth of bacteria and mold. Alternatively, cleaning and drying can be performed on a schedule or at set intervals. Both processes effectively reduce the generation of bacteria, mold, and odors, minimizing environmental pollution. They also reduce the frequency of filter 120 cleaning, lowering replacement costs.

[0075] The dustbin assembly disclosed herein includes a filter that divides the dustbin into a first chamber and a second chamber. The air inlet is located on the wall of the first chamber, while the air outlet and suction outlet are located on the wall of the second chamber. By connecting a cleaning and drying air duct to the outside of the dustbin, hot air can be introduced into the inner cavity of the dustbin to remove dust particles clogging the tiny filter pores, thus cleaning the filter. Simultaneously, the heat from the hot air dries the filter. This self-cleaning and self-drying process can be performed immediately after dust collection, at set times, or at regular intervals, effectively reducing the generation of bacteria, mold, and odors, and minimizing environmental pollution.
