Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a dust box, a dust suction device, a cleaning device and a cleaning system. Background Art

[0002] The working principle of vacuuming by a sweeping machine includes using an electric motor to drive the blades to rotate at high speed, generating negative air pressure in a sealed dust box, sucking dust from surfaces such as carpets and floors, and the dust is sucked into the filter assembly along with the air. The dust is filtered by the filter element in the filter assembly and collected by the dust box, and the clean air after filtration is discharged out of the sweeping machine.

[0003] After the filter has been working for a period of time, a large amount of dust will be adsorbed on the surface of the filter on the dust entry side. The large amount of dust attached to the filter surface will clog the tiny filter sieve holes on the filter surface, thereby affecting the filtering capacity of the filter. When the filter is clogged, either the filter must be disassembled and cleaned, or a new filter must be replaced after disassembly. Either method will take a lot of cleaning time, and the latter will directly lead to the replacement cost of consumables. Summary of the invention

[0004] The present invention provides a dust box, a dust suction device, a cleaning device and a cleaning system to realize the self-cleaning function of a filter component and improve the technical problems of long manual cleaning time and high replacement cost.

[0005] To achieve the above-mentioned purpose and other related purposes, the first aspect of the present invention provides a dust box, which is installed on a cleaning device, including a box body and a filter assembly; the filter assembly is installed in the box body, dividing the inner cavity of the box body into a first chamber and a second chamber, and the first chamber and the second chamber are connected through the pores of the filter assembly; the wall of the first chamber is provided with an openable and closable dust suction port and an openable and closable dust exhaust port, and the wall of the second chamber is provided with an openable and closable air blowing port and an openable and closable air exhaust port; in response to the opening of the air blowing port and the dust exhaust port, the filter assembly is cleaned.

[0006] In the above technical solution, the box body 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 air exhaust port. In response to the opening of the air exhaust port and the dust suction port, the dust suction port, the first chamber, the second chamber and the air exhaust port can form a dust suction channel. The airflow can be used to suck dust from the dust suction port, and the dust is retained in the first chamber through the filter assembly. At the same time, after being filtered by the filter assembly, the clean air enters the second chamber through the pores and is discharged from the air 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 exhaust port. In response to the opening of the air blowing port and the dust exhaust port, the air blowing port, the second chamber, the first chamber and the dust exhaust port form a dust exhaust channel. When the airflow is blown into the second chamber from the air outlet and then enters the first chamber through the pores of the filter assembly, the dust attached to the pores and the side of the filter assembly facing the first chamber can be blown into the first chamber and then discharged through the dust outlet provided in the first chamber. This arrangement realizes the self-cleaning function of the filter assembly, reduces the number of cleaning times, and also reduces the replacement cost of the filter assembly.

[0007] In one embodiment of the dust box of the present invention, the air blowing port is sealed and connected with an air inlet channel, and the air inlet channel connects the air blowing port and the outside of the cleaning device; in response to the opening of the air blowing port and the dust exhaust port, an air flow channel is formed between the air inlet channel and the dust exhaust port, and the air flow channel guides the air flow from the outside of the cleaning device from the air blowing port to the filter component.

[0008] In the above technical solution, the setting of the air inlet channel can realize the connection between the air outlet on the dust box and the outside of the cleaning device. When the air outlet and the dust outlet are opened, an air flow channel is formed between the air inlet channel and the dust outlet. This setting facilitates guiding the air flow from the outside of the cleaning device into the dust box to reduce the impact on other components in the cleaning device.

[0009] In one embodiment of the dust box of the present invention, an openable and closable wind shield 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 shield is arranged in the air inlet channel, which has a relatively sufficient installation space, and a more diverse structure can be selected to drive the wind shield to open and close, thereby reducing the processing difficulty and production cost.

[0011] In one embodiment of the dust box of the present invention, a driving mechanism is provided on the outer side of the air inlet channel, and the driving mechanism drives the wind shield to open or close to control the opening and closing of the air outlet.

[0012] In the above technical solution, the driving mechanism is arranged outside the air inlet channel, so that the driving mechanism can be installed inside the cleaning device, fully utilizing the internal space of the cleaning device and improving the appearance of the cleaning device.

[0013] In one embodiment of the dust box of the present invention, the upper end of the box body has an opening, the opening is connected to a closable box cover, and the first chamber is located below the second chamber.

[0014] In the above technical solution, an opening is arranged at the upper end of the box body, and an openable and closable box cover is connected to the opening. This arrangement enables the box cover to be opened and the filter element to be taken out for cleaning or replacement without taking out the dust box. In addition, the first chamber is arranged below the second chamber, and dust can automatically fall into the first chamber serving as a dust storage space under the action of its own weight without the need for external force, while also reducing the amount of dust attached to the filter assembly. The second chamber is arranged above the first chamber, so that the airflow coming in from the air outlet blows away the dust attached to the filter assembly, and the dust can automatically fall into the first chamber to avoid being reattached to the filter assembly.

[0015] In one embodiment of the dust box of the present invention, the wall of the first chamber includes an inclined wall that gradually inclines from top to bottom toward the first chamber, the dust suction port is arranged on the inclined wall, and a first baffle that can be opened and closed is installed on the inner side of the inclined wall, and the first baffle covers the dust suction port.

[0016] In the above technical solution, the wall of the first chamber includes an inclined wall, the dust suction port is opened on the inclined wall, and a first baffle that can be opened and closed is arranged on the inner side of the inclined wall. When the first baffle is used for dust suction without external force, it can be closed only by its own weight to prevent dust from flowing out of the dust suction port. At the same time, the open state can be achieved by external suction force to resist gravity and perform dust suction operation. The structure is simple in design, low in cost, and occupies little space.

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

[0018] In the above technical solution, the setting of the locking member can realize the fixation of the box body inside the cleaning device, and the cooperation between 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 the present invention, at least one limiting portion is provided on the periphery of the box body, and the limiting portion includes a groove sunken toward the inside of the box body, and the groove cooperates with the outside to limit the position of the box body.

[0020] In the above technical solution, the setting of the limit part can realize the limitation of the position of the dust box. On the one hand, it is convenient to guide the installation and improve the installation efficiency; on the other hand, the limit part in the form of a groove can cooperate with the external structural part to realize the limitation of multiple degrees of freedom of the dust box and improve the firmness and reliability of the dust box in the cleaning device.

[0021] A second aspect of the present invention further provides a dust suction device, which includes a suction generator and any one of the dust boxes described above, wherein the suction generator is connected to the air outlet.

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

[0023] The third aspect of the present invention further provides a cleaning device, which includes a base body and the above-mentioned dust suction device, wherein the base body has a mounting position, and the dust suction device is detachably mounted on the mounting position.

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

[0025] In one embodiment of the cleaning device of the present invention, the base also includes a first vent, a second vent and a third vent arranged 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 connected to the air blowing port on the outer surface of the cleaning device, the airflow is introduced into the dust box to spray and clean the filter assembly. By providing a second vent connected to the dust exhaust port on the outer surface of the cleaning device, the dust temporarily stored in the first chamber is collected outside the cleaning device to self-clean the dust box. By providing a third vent connected to the dust suction port at the bottom of the cleaning device, the surface in contact with the bottom of the cleaning device is cleaned.

[0027] A fourth aspect of the present invention further provides a cleaning system, which includes the above-mentioned cleaning device and a base station compatible with the cleaning device.

[0028] In the above technical solution, the cleaning system including the cleaning device realizes the self-cleaning function of the filter component, reduces the cleaning times, and also reduces the replacement cost of the filter component.

[0029] In an embodiment of the cleaning system of the present invention, the base station comprises an air blowing generator, and the air blowing generator comprises an air outlet capable of communicating with the first ventilation port.

[0030] In the above technical solution, by arranging a blowing generator at the base station, air can be blown into the dust box through the first vent and the air inlet. On the one hand, the dust attached to the filter assembly can be blown into the first chamber to achieve self-cleaning of the filter assembly. On the other hand, the dust in the first chamber can be blown into the external dust collection device to achieve self-cleaning of the dust box.

[0031] The dust box of the present invention 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 air exhaust port. In response to the opening of the air exhaust port and the dust suction port, the dust suction port, the first chamber, the second chamber and the air exhaust port can form a dust suction channel. The airflow can be used to suck dust from the dust suction port, and the dust is left in the first chamber through the filter assembly. At the same time, after being filtered by the filter assembly, the clean air enters the second chamber through the pores and is discharged from the air 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 exhaust port. In response to the opening of the air blowing port and the dust exhaust port, the air blowing port, the second chamber, the first chamber and the dust exhaust port form a dust exhaust channel. When the airflow is blown into the second chamber from the air outlet and then enters the first chamber through the pores of the filter assembly, the dust attached to the pores and the side of the filter assembly facing the first chamber can be blown into the first chamber and then discharged through the dust outlet provided in the first chamber. This arrangement realizes the self-cleaning function of the filter assembly, reduces the number of cleaning times, and also reduces the replacement cost of the filter assembly.

[0050] See also Figures 1 to 12 The present invention provides a dust box 100, a dust collecting device 10, a cleaning device 1 and a cleaning system. The box body 110 of the dust box 100 is divided into a first chamber 130 and a second chamber 140 by a filter assembly 120. An openable and closable air blowing port 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 blowing port 141 and the dust exhaust port 132, the air blowing port 141, the second chamber 140, the first chamber 130 and the dust exhaust port 132 form a dust exhaust channel. When the air flow is blown toward the second chamber 140 through the air outlet 141 and then enters the first chamber 130 through the pores of the filter component 120, the dust attached to the pores and the side of the filter component 120 facing the first chamber 130 can be blown into the first chamber 130, thereby realizing the self-cleaning function of the filter component 120, reducing the number of cleaning times, and reducing the replacement cost of the filter component 120.

[0051] See also Figure 8 and Fig.10 The dust box 100 involved in the present invention is installed on the cleaning device 1. The cleaning device 1 involved in the present invention can be a floor scrubber, a floor sweeper, a cleaning robot, etc., but is not limited thereto. Taking the cleaning robot as an example, in order to exert its cleaning function, the cleaning device 1 at least includes a dust suction device 10 for collecting and removing dust on the ground. Specifically, the dust suction 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 high-speed rotation to suck dust into the dust box 100. In order to improve the dust suction efficiency, the dust is concentrated in advance. In some embodiments, the dust suction device 10 is also equipped with a cleaning member such as a roller brush.

[0052] In some embodiments, the cleaning device 1 also has a wet cleaning device for realizing the wet cleaning function, and the wet cleaning device includes a cleaning head, a liquid storage tank, a pump body and a pipeline assembly, etc. In some other embodiments, the cleaning device 1 also includes an intelligent control system, and the intelligent control system can integrate multiple functions according to actual needs. It can include but is not limited to the autonomous travel planning function based on sensors such as accelerometers, gyroscopes, odometers, etc., the obstacle recognition and anti-collision function based on devices such as distance sensors and image recognition devices, the autonomous walking function based on mechanical mechanisms such as driving wheels, driven wheels and drivers, the human-computer interaction function based on devices such as physical buttons, virtual cases, display screens and indicator lights, the energy supply function based on rechargeable batteries, etc., and the intelligent control function based on control circuits or control chips, etc., which will not be described one by one.

[0053] See also Figure 1 and Figure 2 In an example of the dust box 100 involved in the present invention, the dust box 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, round, polygonal or other irregular shapes. The box body 110 in this embodiment is roughly in the shape of a horizontally placed polygonal body. This arrangement can be reasonably arranged with other components in the cleaning device 1, and a higher utilization rate can be achieved in a limited space.

[0054] See also Figure 1 and Figure 2 , the filter assembly 120 is installed in the box body 110, and the inner cavity of the box body 110 is divided into a first chamber 130 and a second chamber 140, and 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 a certain angle to the horizontal direction. When the filter assembly 120 is placed horizontally, the first chamber 130 and the second chamber 140 are arranged up and down; when the filter assembly 120 is placed vertically, the first chamber 130 and the second chamber 140 are arranged front and back; when the filter assembly 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 many ways to install the filter assembly 120, including but not limited to threaded connection, card connection or plug-in connection, as long as the first chamber 130 and the second chamber 140 can be isolated, fixed in the box body 110, and the connection with the box body 110 can be sealed.

[0055] See also Figure 1 and Figure 2In this embodiment, the filter assembly 120 includes a filter element 121 and a filter element mounting seat 122, and the filter element 121 is detachably mounted on the filter element mounting seat 122. The filter element 121 is arranged to be detachable, which is convenient for cleaning and replacing the filter element 121. In particular, when replacement is required, only the filter element 121 needs to be replaced, and the entire filter assembly 120 does not need to be replaced. In addition, this arrangement facilitates the adaptive design of the filter element mounting seat 122, reduces the difficulty of design and processing, and adapts to the space in the box body 110 and the shape of the filter element 121. There are many choices of materials for the filter element 121, including but not limited to HEPA (High Efficiency Particulate Air) filter, activated carbon filter, polyester fiber filter or nylon fiber filter. The inner wall of the first chamber 130 and / or the inner wall of the second chamber 140 are connected with a surrounding mounting plate 123, and the filter element mounting seat 122 is sealed and connected to the mounting plate 123. The arrangement of the mounting plate 123 facilitates the fixing of the filter element mounting seat 122. The sealed connection between the filter element mounting seat 122 and the mounting plate 123 reduces the possibility of dust entering the second chamber 140 through the mounting gap, which is beneficial to improving the filtering efficiency of the filter assembly 120.

[0056] To achieve the dust collection function of the filter assembly 120, please refer to Figure 1 , Figure 2 and Fig. 9The wall of the first chamber 130 is provided with an openable and closable dust suction port 131 and an openable and closable dust exhaust port 132, and the wall of the second chamber 140 is provided with an openable and closable air blowing port 141 and an openable and closable air exhaust port 142. The positions of the dust suction port 131, the dust exhaust port 132, the air blowing port 141 and the air exhaust port 142 are not limited. For example, the dust suction port 131 and the dust exhaust port 132 can be provided on the side wall or the bottom wall of the first chamber 130, and the air blowing port 141 and the air exhaust port 142 can start from the side wall or the bottom wall of the second chamber 140. It should be noted that, in some embodiments, the openability of the dust suction port 131, the dust discharge port 132, the blowing port 141 and the exhaust port 142 is controlled by an openable and closable opening and closing structure, and the opening and closing structure can be arranged on the inner side or outer side of the wall body at the opening of the dust suction port 131, the dust discharge port 132, the blowing port 141 and the exhaust port 142, as well as other positions capable of controlling the opening and closing. For example, an openable and closable first baffle 134 is arranged on the inner side of the wall body at the opening of the dust suction port 131; an openable and closable second baffle 135 is arranged on the outer side of the wall body at the opening of the dust discharge port 132; an air inlet channel 150 is arranged between the blowing port 141 and the outer surface of the cleaning device 1, and an openable and closable windshield 151 is arranged in the air inlet channel 150; an openable and closable baffle is arranged on the wall body at the opening of the exhaust port 142, and other opening and closing structures are arranged in the suction generator 200 connected thereto, etc. (not shown in the figure). The opening and closing structures provided on the dust suction port 131, the dust exhaust port 132, the air blowing port 141 and the air exhaust port 142 can be opened by the high-pressure airflow provided by an external fan, electrical control or mechanical control, and the closing of the opening and closing structures provided on the dust suction port 131, the dust exhaust port 132, the air blowing port 141 and the air exhaust port 142 can be achieved by self-weight, spring reset, electrical control or mechanical control, and there is no limitation on this.

[0057] See also Figure 1 , Figure 2 and Fig. 9 , the suction generator 200 draws air at the air outlet 142 to suck dust from the dust suction port 131. At this time, the dust suction port 131, the first chamber 130, the second chamber 140 and the air outlet 142 form a dust suction channel. Dust enters the first chamber 130 from the dust suction port 131, and the filter component 120 leaves the dust in the first chamber 130. At the same time, the clean air filtered by the filter component 120 enters the second chamber 140 through the pores and is discharged from the air outlet 142 to achieve dust collection. When the intelligent control system detects that the cleaning device 1 is performing dust collection, it controls the dust outlet 132 and the air outlet 141 to close, which is conducive to maintaining the airtightness of the dust box 100, so that there is a higher negative pressure in the dust box 100 to achieve an efficient dust collection effect.

[0058] See also Figure 1 , Figure 2 and Fig. 9In one embodiment, when the intelligent control system detects that the cleaning device 1 stops the dust collection work, in response to the opening of the air outlet 141 and the dust outlet 132, the air outlet 141, the second chamber 140, the first chamber 130 and the dust outlet 132 form a dust discharge channel. Specifically, when the air outlet 141 is opened, air can be blown from the air outlet 141 toward the side of the filter assembly 120 facing the second chamber 140. When the airflow passes through the pores of the filter assembly 120 and enters the first chamber 130, the dust attached to the pores and the side of the filter assembly 120 facing the first chamber 130 can be blown into the first chamber 130 to complete the work of 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 the air blowing generator, or by connecting the dust outlet 132 to the suction device, which is not limited to this. The dust blown into the first chamber 130 is then discharged through the dust outlet 132 set in the first chamber 130. This setting realizes the self-cleaning function of the filter assembly 120, reduces the number of cleaning times, and also reduces the replacement cost of the filter assembly 120. In addition, the airflow for cleaning the filter assembly 120 is blown from the back of the filter assembly 120 to the front of the filter assembly 120 to achieve the best cleaning effect. It should be noted that the definition of the back and front of the filter assembly 120 is: during cleaning, dust is sucked into the dust box 100 through the dust inlet of the dust box 100, and the filter assembly 120 is filtered. At this time, the filtering surface of the filter assembly 120 is the front, and the opposite surface is the back.

[0059] See also Figures 7 to 9 In one embodiment of the dust box 100 involved in the present invention, the blowing port 141 is sealed and connected with an air inlet channel 150, and the air inlet channel 150 connects the blowing port 141 and the outside of the cleaning device 1. The shape of the air inlet channel 150 is not limited, as long as the blowing port 141 and the outside of the cleaning device 1 can be connected. The sealed connection between the air inlet channel 150 and the blowing port 141 can be achieved by arranging a silicone rubber sealing ring or a foam sealing ring in the circumferential direction of the connection between the air inlet channel 150 and the blowing port 141. In response to the opening of the blowing port 141 and the dust outlet 132, an air flow channel is formed between the air inlet channel 150 and the dust outlet 132, and the air flow channel guides the air flow from the outside of the cleaning device 1 to the filter assembly 120 from the blowing port 141. Specifically, the air flow enters from the air inlet channel 150, passes through the blowing port 141, the second chamber 140, the filter assembly 120 and the first chamber 130, and finally is discharged from the dust outlet 132. The airflow can blow the dust and garbage dust attached to the pores and the side of the filter assembly 120 facing the first chamber 130 into the first chamber 130, completing the work of cleaning the filter assembly 120. The provision of the air inlet channel 150 facilitates the guidance of the airflow from the outside of the cleaning device 1 into the dust box 100, facilitates the entry of the airflow, and reduces the impact on other components in the cleaning device 1.

[0060] See also Figures 7 to 9 In one embodiment of the dust box 100 involved in the present invention, an openable and closable windshield 151 is provided in the air inlet channel 150 to control the opening and closing of the air outlet 141. The shape of the windshield 151 is adapted to the inner wall of the air inlet channel 150 to achieve a better windshield effect when the windshield 151 is closed. According to the different shapes of the air inlet channel 150, the opening of the windshield 151 can be rotation, folding or insertion, which is not limited. In this embodiment, the windshield 151 and the air inlet channel 150 are rotatably connected by a rotating shaft, and the windshield 151 is closed by rotating it to a position perpendicular to the air inlet channel 150, and is opened by rotating it to a position parallel to the air inlet channel 150. There are many ways to drive the windshield 151 to open and close, which can be achieved by motor control or by setting elastic members on the windshield 151 and the air inlet channel 150. It should be noted that in an embodiment in which the elastic member controls the opening and closing of the windshield 151, the windshield 151 can be in a normally closed state under the action of the elastic member. When the cleaning of the filter assembly 120 begins, the airflow acting on the windshield 151 can overcome the elastic force of the elastic member to open the windshield 151. When the cleaning of the filter assembly 120 ends, the windshield 151 resumes closing under the action of the elastic member. In order to achieve the closure of the windshield 151 during the dust collection process and the opening of the filter assembly 120 during the cleaning process, it is necessary to set the wind force of the suction generator 200 to be less than the resistance of the elastic member, and the wind force of the filter assembly 120 to be greater than the resistance of the elastic member. The windshield 151 is arranged in the air inlet channel 150, so that the windshield 151 has a relatively sufficient installation space, which can reduce the limitation of the installation space on the structure of driving the windshield 151 to open and close, increase the selection space of the types of structural forms driving the windshield 151 to open and close, and thus reduce the processing difficulty and production cost.

[0061] See also Figures 7 and 8 In one embodiment of the dust box 100 involved in the present invention, a driving mechanism 152 is provided on the outside of the air inlet channel 150, and the windshield 151 is driven to open or close by the driving mechanism 152 to control the opening and closing of the air outlet 141. The driving mechanism 152 can be in various forms, such as motor drive, synchronous belt drive, gear drive or electromagnetic drive, etc., which are not limited to this. The driving mechanism 152 is arranged on the outside of the air inlet channel 150, and the driving mechanism 152 can be installed inside the cleaning device 1, so as to make full use of the internal space of the cleaning device 1, and can also protect the driving mechanism 152. In this embodiment, a motor drive is adopted, and the motor can be connected to the intelligent control system for control, so as to realize the automatic control of the opening or closing of the windshield 151 by the intelligent control system.

[0062] See also Figure 1 to Figure 2In one embodiment of the dust box 100 of the present invention, the upper end of the box body 110 has an opening 111, and the opening 111 is connected to a closable box cover 160, and the first chamber 130 is located below the second chamber 140. The opening 111 is arranged at the upper end of the box body 110, and the closable box cover 160 is connected to the opening 111, so that the box cover 160 can be opened without taking out the dust box 100, and the filter element 121 can be taken out for cleaning or replacement. In addition, the first chamber 130 is arranged below the second chamber 140, and dust can automatically fall into the first chamber 130 as a dust storage space under the action of its own weight without the need for external force, and the amount of dust attached to the filter assembly 120 can also be reduced. The second chamber 140 is disposed above the first chamber 130, so that the dust attached to the filter assembly 120 can be blown off by the airflow from the air outlet 141 and automatically fall into the first chamber 130 to avoid being reattached to the filter assembly 120. It should be noted that the filter assembly 120 can be placed horizontally or at an angle less than 45° to the horizontal direction, as long as the first chamber 130 can be located below the second chamber 140.

A first baffle 134 which can be opened and closed is installed on the inner side of the inclined wall 133, and the first baffle 134 covers the dust suction port 131. This arrangement can realize that the first baffle 134 can realize the closed state only by relying on its own weight when there is no external force to suck, so as to prevent dust from flowing out of the dust suction port 131, and at the same time, the first baffle 134 can realize the open state by resisting gravity by the external force of suction, so as to perform dust suction operation. The structure is simple in design, low in cost, and small in space.

In this embodiment, the base 20 has a mounting position 240, and the dust collecting device 10 is detachably installed in the mounting position 240. The mounting position 240 can be a part of a recessed structure, which is adapted to the dust collecting device 10 to accommodate the dust collecting device 10. The dust collecting device 10 is limited by the limiting portion 170, and the dust collecting device 10 is also limited by the limiting portion 170. The dust collecting device 10 is locked and fixed by the locking member 180, and the dust collecting device 10 is also locked and fixed by the locking member 180. The cleaning device 1 including the dust collecting device 10 realizes the self-cleaning function of the filter assembly 120 , reduces the number of cleaning times, and also reduces the replacement cost of the filter assembly 120 .

[0068] See also Figures 10 to 12In one embodiment of the cleaning device 1 involved in the present invention, the base 20 also includes a first vent 210, a second vent 220, and a third vent 230 arranged on the outer surface. The position of the first vent 210 is not limited.
