Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically to a dust and gas separation device, a cleaning device, and a cleaning method. Background Technology

[0002] Cleaning devices such as mite removers and vacuum cleaners typically use a vacuum pump to generate suction force, sucking up dust and other dirt from the surface to be cleaned. Then, a dust-air separation device separates the airflow carrying dust and other dirt, filtering and collecting the dust. Finally, the relatively clean airflow is released into the environment, thus achieving a cleaning effect.

[0003] Existing dust-air separation devices have at least the following problems: when cleaning dust and other dirt in the dust cup, sometimes it is impossible to empty the dust cup completely, and some dirt will remain on the cup wall, resulting in poor dust removal effect and low dust removal efficiency. After long-term use, it will also lead to internal contamination of the dust cup, affecting subsequent user use, and may even breed bacteria; after dust is sucked up, some dust will adhere to the surface of the filter screen, which can easily cause filter screen blockage and affect use. Summary of the Invention

[0004] In view of this, the present invention provides a dust-gas separation device, a cleaning device, and a cleaning method to solve the problems of poor dust removal effect, low dust removal efficiency, easy internal contamination, and easy clogging of the filter screen in existing dust-gas separation devices.

[0005] In a first aspect, the present invention provides a dust-gas separation device, comprising:

[0006] The dust cup has a dust collection chamber and a cyclone chamber arranged side by side and connected to each other inside the dust cup, and a separator assembly is arranged inside the cyclone chamber;

[0007] The cup lid is detachably connected to the dust cup.

[0008] A dust cup scraper assembly is connected to the cup lid. One end of the dust cup scraper assembly away from the cup lid is placed in the dust collection chamber, and the outer edge of this end slides against the inner wall of the dust collection chamber. The dust cup scraper assembly can move with the cup lid in the dust collection chamber.

[0009] A dust scraper is disposed inside the cyclone chamber. The dust scraper is movable relative to the separator assembly to scrape off the dust on the outer wall of the filter screen on the separator assembly.

[0010] Beneficial effects: By installing a dust cup scraper assembly connected to the cup lid inside the dust collection chamber of the dust cup, and allowing the dust cup scraper assembly to move along the dust collection chamber with the cup lid, when cleaning dust and other dirt on the inner wall of the dust cup, the cup lid is pulled outward in the direction away from the dust collection chamber. The cup lid causes the dust cup scraper assembly to move relative to the inner wall of the dust collection chamber, thereby scraping away the dust in the dust collection chamber, improving the dust removal efficiency and effect, and avoiding internal contamination and bacterial growth in the dust cup. By installing a filter scraper component inside the cyclone chamber, this filter scraper component can move relative to the separator assembly installed in the cyclone chamber, thereby scraping away the dust on the outer wall of the filter screen of the separator assembly, preventing filter screen clogging and facilitating use.

[0011] In one alternative embodiment, the end face of the dust cup scraper assembly facing the bottom surface of the dust cup is in contact with the bottom surface of the dust cup.

[0012] Beneficial effects: It allows the dust cup scraper assembly to move to its maximum range within the dust cup collection chamber, increasing the cleaning area. During cleaning, pulling the dust cup scraper assembly can scrape away dust from the entire inner wall of the collection chamber, improving the scraping efficiency and effect of the dust cup scraper assembly.

[0013] In one alternative embodiment, the dust cup scraper assembly includes a scraper blade placed inside the dust collection chamber, with the outer edge of the scraper blade slidingly abutting against the inner wall of the dust collection chamber.

[0014] Beneficial effects: The outer edge of the scraper slides and abuts against the inner wall of the dust collection chamber, making the scraper in relatively close contact with the inner wall of the dust collection chamber, thus improving the dust removal effect.

[0015] In one alternative embodiment, the scraper is arranged perpendicular to the axial direction of the dust collection chamber.

[0016] Beneficial effects: The vertical axial arrangement of the scraper in the dust collection chamber increases the contact area between the scraper and the inner wall of the dust collection chamber, further improving the dust removal effect.

[0017] In one alternative embodiment, the dust cup scraper assembly further includes a connecting rod, through which the scraper is connected to the cup lid.

[0018] Beneficial effect: By setting a connecting rod, when the cup lid is removed, it is easy to move the scraper along with the cup lid to scrape away the dust in the dust collection chamber.

[0019] In one optional embodiment, a limiting structure is provided at one end of the dust collection chamber near the cup lid to restrict the dust cup scraper assembly from detaching.

[0020] Beneficial effects: By setting a limiting structure at the opening of the dust collection chamber, the dust cup scraper assembly can be prevented from being pulled out of the dust collection chamber during use. At the same time, by continuing to pull the dust cup scraper assembly, the dust cup can be removed. This cleans the dust in the dust collection chamber and the dust on the outer wall of the filter screen at the same time, making the operation convenient and further improving the cleaning efficiency.

[0021] In one optional embodiment, the dust cup scraper assembly and the cup lid are an integral structure.

[0022] Beneficial effects: The integrated structure reduces the number of parts required during assembly, making assembly more convenient, improving the assembly efficiency of the dust cup scraper assembly and the cup lid, and enhancing the reliability and stability of the dust cup scraper assembly.

[0023] In one optional embodiment, a cyclone duct is formed inside the cyclone cavity, a cyclone shield is provided inside the cyclone duct, the cyclone shield is fitted over the outside of the filter screen, and the filter screen dust scraping component is located at the bottom of the cyclone shield.

[0024] Beneficial effects: When cleaning the filter screen, the dust scraper component located at the bottom of the cyclone cover outside the filter screen adheres closely to the outer wall of the filter screen. When the dust cup is removed, the dust scraper component moves along the filter screen and scrapes off the dust. The filter screen can be cleaned at the same time as the dust cup is removed, thus improving the cleaning efficiency of the filter screen.

[0025] In one alternative embodiment, the filter dust scraping component includes a scraper strip arranged circumferentially around the cyclone shroud, the scraper strip abutting against the outer wall of the filter screen.

[0026] Beneficial effects: By setting a circumferential scraper around the cyclone shield, the contact area between the scraper and the outer wall of the filter screen can be increased, and the scraper and the outer wall of the filter screen can be made to be in relatively close contact, thereby further improving the cleaning effect.

[0027] In one alternative embodiment, the system further includes a motor duct, the separator assembly is mounted in the motor duct, and the dust cup is fitted outside the separator assembly and mounted in the motor duct.

[0028] Beneficial effects: The dust cup has a simple installation structure and a small size. In addition, the motor air duct is mainly located in the upper part of the main unit, saving the volume of the lower part of the main unit and reducing the size of the main unit.

[0029] In a second aspect, the present invention also provides a cleaning device, comprising: a dust-gas separation device as described in any alternative embodiment of the first aspect.

[0030] Beneficial effects: Since the cleaning device includes a dust-air separation device, it has the same effect as the dust-air separation device, which will not be elaborated here.

[0031] In one alternative implementation, the cleaning device includes at least one of a mite remover, a vacuum cleaner, a robotic vacuum cleaner, and a robotic window cleaner.

[0032] Beneficial effects: This dust-gas separation device is suitable for a variety of cleaning devices and has strong applicability.

[0033] Thirdly, the present invention also provides a cleaning method, applied to the dust-gas separation device of any optional embodiment of the first aspect or the cleaning device of any optional embodiment of the second aspect, wherein the method includes the following steps:

[0034] When the dust collection chamber needs to be cleaned, pull the cup cover outward in a direction away from the dust collection chamber. The dust cup scraper component moves with the cup cover inside the dust collection chamber to scrape off the dust on the inner wall of the dust collection chamber.

[0035] When the filter needs to be cleaned, the dust cup is removed from the motor duct, and the filter scraper moves relative to the separator assembly to scrape off the dust from the outer wall of the filter on the separator assembly.

[0036] Beneficial effects: This cleaning method can clean the dust collection chamber and the filter screen separately. The cleaning process of the dust collection chamber and the filter screen are independent of each other. Users can choose to clean the dust collection chamber or the filter screen as needed. It is highly flexible in operation, can meet different user needs, and improve the user experience.

[0037] In an alternative embodiment, it also includes:

[0038] When the dust collection chamber and the filter screen need to be cleaned, pull the cup cover outward in a direction away from the dust collection chamber. The dust cup scraping component moves with the cup cover inside the dust collection chamber to scrape off the dust on the inner wall of the dust collection chamber. Then continue to pull the cup cover outward. When the dust cup scraping component is limited by the limiting structure, the cup cover drives the dust cup to disengage from the motor air duct. The filter screen scraping component moves relative to the separator assembly to scrape off the dust on the outer wall of the filter screen on the separator assembly.

[0039] Beneficial effects: This cleaning method can continue to clean the filter screen while cleaning the dust collection chamber, that is, to achieve a linkage cleaning process between the inner wall of the dust collection chamber and the outer wall of the filter screen. In this process, the cleaning is still in sequence, that is, first clean the inner wall of the dust collection chamber, and then continue to clean the outer wall of the filter screen. This cleaning method is more efficient, convenient and flexible to operate, meets different usage needs, and improves the user experience. Attached Figure Description

[0061] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] The following combination Figures 1 to 9 The following describes embodiments of the present invention.

[0063] According to an embodiment of the present invention, a dust-air separation device is provided, including a dust cup 1, a cup lid 2, a dust cup scraping assembly 3, and a filter screen scraping component 4. The dust cup 1 has a dust collection chamber 101 and a cyclone chamber 102 arranged side by side and communicating with each other. A separator assembly 5 is arranged in the cyclone chamber 102. The cup lid 2 is detachably connected to the dust cup 1. The dust cup scraping assembly 3 is connected to the cup lid 2. One end of the dust cup scraping assembly 3 away from the cup lid 2 is placed in the dust collection chamber 101 and the outer edge of this end slides against the inner wall of the dust collection chamber 101. The dust cup scraping assembly 3 can move with the cup lid 2 in the dust collection chamber 101. The filter screen scraping component 4 is arranged in the cyclone chamber 102 and can move relative to the separator assembly 5 arranged in the cyclone chamber 102 to scrape off the dust on the outer wall of the filter screen 502 on the separator assembly 5.

[0064] In this embodiment, the dust-air separation device can be installed on the main unit 1001 of a cleaning device such as a mite remover or a vacuum cleaner. A dust cup scraper assembly 3, connected to a cup lid 2, is installed inside the dust collection chamber 101 of the dust cup 1. This dust cup scraper assembly 3 moves with the cup lid 2 within the dust collection chamber 101. When cleaning dust and other dirt from the inner wall of the dust cup 1, the cup lid 2 is pulled outwards away from the dust collection chamber 101. The cup lid 2 causes the dust cup scraper assembly 3 to move relative to the inner wall of the dust collection chamber 101, thus scraping away the dust and improving cleaning efficiency and effect, while preventing internal contamination and bacterial growth in the dust cup 1. A filter scraper assembly 4 is installed inside the cyclone chamber 102. This filter scraper assembly 4 can move relative to the separator assembly 5 installed within the cyclone chamber 102, thereby scraping away dust from the outer wall of the filter screen 502 of the separator assembly 5, reducing clogging of the filter screen 502 and facilitating use.

[0065] like Figure 1 As shown, in one embodiment, the end face of the dust cup scraper assembly 3 facing the bottom surface of the dust cup 1 is in contact with the bottom surface of the dust cup 1.

[0066] In this embodiment, when the dust cup 1 and the cup cover 2 are in the assembled state, the dust cup scraper assembly 3 is placed entirely inside the dust collection chamber 101 of the dust cup 1. At this time, the end face of the dust cup scraper assembly 3 facing the bottom surface of the dust cup 1 is in contact with the bottom surface of the dust cup 1, which allows the dust cup scraper assembly 3 to move within the dust collection chamber 101 of the dust cup 1 to the maximum extent and to the maximum cleaning range. During cleaning, pulling the dust cup scraper assembly 3 can scrape off the dust on the entire inner wall of the dust collection chamber 101, thereby improving the dust scraping efficiency and effect of the dust cup scraper assembly 3.

[0067] In one embodiment, the dust cup scraper assembly 3 includes a scraper 301, which is placed inside the dust collection chamber 101, and the outer edge of the scraper 301 slides against the inner wall of the dust collection chamber 101. The dust collection chamber 101 is a near-cylindrical cavity, and the scraper 301 is disposed inside the dust collection chamber 101. The cross-sectional area of ​​the scraper 301 is adapted to the cross-sectional area of ​​the dust collection chamber 101, and the cross-section of the dust collection chamber 101 is a surface perpendicular to the axial direction of the dust collection chamber 101.

[0068] Furthermore, the scraper 301 is arranged perpendicular to the axial direction of the dust collection chamber 101. This structure allows the outer edge of the scraper 301 to be in relatively close contact with the inner wall of the dust collection chamber 101. When the scraper 301 is pulled, the edge of the scraper 301 generates relative friction with the inner wall of the dust collection chamber 101, which causes the scraper 301 to scrape off the dust adhering to the inner wall of the dust collection chamber 101, improving the dust removal effect. Moreover, the fact that the scraper 301 is arranged perpendicular to the axial direction of the dust collection chamber 101 can increase the contact area between the scraper 301 and the inner wall of the dust collection chamber 101, further improving the dust removal effect.

[0069] like Figure 1As shown, in one embodiment, the dust cup scraper assembly 3 further includes a connecting rod 302, and the scraper 301 is connected to the cup lid 2 through the connecting rod 302.

[0070] In this embodiment, one end of the connecting rod 302 is connected to the scraper 301, and the other end is connected to the cup lid 2. The length direction of the connecting rod 302 is parallel to the axial direction of the dust collection chamber 101, which can minimize the length of the connecting rod 302. By setting the connecting rod 302, when the cup lid 2 is removed, it is easy to drive the scraper 301 to move with the cup lid 2 to scrape the dust on the inner wall of the dust collection chamber 101.

[0071] In other embodiments, the scraper 301 is arranged axially along the dust collection chamber 101, and the dust cup scraper assembly 3 further includes a mounting rod. One end of the mounting rod is connected to the connecting rod 302, and the other end is connected to the scraper 301. The length of the scraper 301 is less than or equal to the length of the dust collection chamber 101, and the outer edge of the scraper 301 is in contact with the inner wall of the dust collection chamber 101. The scraper 301 can rotate relative to the dust collection chamber 101 with the cup lid 2. When cleaning the dust collection chamber 101, the cup lid 2 is removed, and then the cup lid 2 is rotated. The cup lid 2 drives the scraper 301 to rotate circumferentially along the inner wall of the dust collection chamber 101 through the connecting rod 302 and the mounting rod to scrape off the dust on the inner wall of the dust collection chamber 101. Then, the dust in the dust collection chamber 101 is cleaned by tilting the dust cup 1.

[0072] In one embodiment, the dust cup scraper assembly 3 and the cup cover 2 are an integral structure. The integral structure reduces the number of parts required during assembly, making assembly more convenient. It can improve the assembly efficiency of the scraper 301, the connecting rod 302 and the cup cover 2, and improve the reliability and stability of the connecting rod 302 driving the scraper 301 to move in the dust collection chamber 101.

[0073] like Figure 1 and 2 As shown, in one embodiment, the dust-gas separation device further includes a motor duct 7, a separator assembly 5 is installed in the motor duct 7, and a dust cup 1 is fitted outside the separator assembly 5 and installed in the motor duct 7.

[0074] In this embodiment, the motor duct 7 is installed on the upper part of the main unit 1001. The main unit 1001 is provided with a dust outlet. The separator assembly 5 is disposed inside the cyclone chamber 102 and installed on the motor duct 7. The dust cup 1 is fitted onto the outside of the separator assembly 5 and then installed on the motor duct 7. The side wall of the dust cup 1 is provided with an air inlet and an air outlet communicating with the cyclone chamber 102. The air inlet and the dust outlet are connected. The separator assembly 5 includes a separator body 501, a filter screen 502, and a HEPA filter element 503. The filter screen 502 is made of metal and is embedded outside the separator body 501. The HEPA filter element 503 is disposed inside the separator body 501. By installing the dust cup 1 through the above installation structure, the installation of the dust cup 1 is relatively simple and the volume is small. In addition, the motor duct 7 is mainly located in the upper part of the main unit 1001, saving the volume of the lower part of the main unit 1001 and reducing the overall volume of the main unit 1001.

[0075] like Figure 1 As shown, in one embodiment, a cyclone duct 1021 is formed inside the cyclone cavity 102, and a cyclone shield 6 is provided inside the cyclone duct 1021. The cyclone shield 6 is fitted over the outside of the filter screen 502, and the filter screen dust scraping component 4 is provided at the bottom of the cyclone shield 6.

[0076] In this embodiment, the cyclone duct 1021 has a spiral structure. One end of the cyclone duct 1021 is connected to the air inlet, and the other end extends inside the cyclone cavity 102 and communicates with the dust collection cavity 101. The cyclone shield 6 is disposed inside the upper part of the cyclone duct 1021 and is connected to the cyclone duct 1021. In the assembled state, the cyclone shield 6 is positioned above the outside of the filter screen 502, and the filter screen dust scraping component 4 is in close contact with the outer wall of the filter screen 502.

[0077] When cleaning the filter 502, the dust cup 1 is removed, and the cyclone cover 6 moves along the axis of the filter 502 along with the dust cup 1. At the same time, the filter dust scraper 4 moves along the outer wall of the filter 502 to scrape off the dust on the filter 502. In other words, the filter 502 can be cleaned at the same time as the dust cup 1 is removed, which improves the cleaning efficiency of the filter 502.

[0078] In one embodiment, the filter dust scraping component 4 includes a scraper strip, which is arranged circumferentially around the cyclone shroud 6 and abuts against the outer wall of the filter screen 502. The scraper strip is made of a material with a certain degree of elasticity, such as rubber, and is integrally formed with the bottom of the cyclone shroud 6. During installation, the cyclone shroud 6 is fitted outside the separation chamber assembly, and the scraper strip is set tightly against the outer wall of the filter screen 502, which can increase the contact area between the scraper strip and the outer wall of the filter screen 502 and make the scraper strip and the outer wall of the filter screen 502 in relatively close contact, thereby improving the cleaning effect.

[0079] When the cleaning device is working, the gas containing dust from the outside enters the cyclone chamber 102 through the air inlet. The dust and air are separated by the separator assembly 5. After passing through the spiral cyclone duct 1021, the dust is thrown into the dust collection chamber 101 and collected and stored in the dust collection chamber 101. The clean air is discharged from the dust cup 1 through the air outlet.

[0080] In one embodiment, a limiting structure is provided at one end of the dust collection chamber 101 near the cup lid 2 to prevent the dust cup scraper assembly 3 from detaching. This limiting structure includes a baffle (not shown in the figure) located on the side of the dust collection chamber 101 near the cup lid 2. The baffle has a through hole for the connecting rod 302 to pass through and move along the dust collection chamber 101. The area of ​​the through hole is slightly smaller than the cross-sectional area of ​​the dust collection chamber 101, so that while preventing the scraper 301 from detaching, the emptying of the dust collection chamber 101 is not affected. By providing a limiting structure at the cup opening of the dust collection chamber 101, the scraper 301 is prevented from being pulled out of the dust collection chamber 101 during use. This allows the scraper 301 to continue pulling, enabling the scraper 301 to remove the dust cup 1 from the motor duct 7, thus achieving a coordinated cleaning process of the inner wall of the dust collection chamber 101 and the outer wall of the filter screen 502, further improving cleaning efficiency.

[0081] In this embodiment, as Figure 4 and 5 As shown, a sliding limiting mechanism is also provided between the dust cup 1 and the cup lid 2. The sliding limiting mechanism includes a slide rod 801 and a slide groove 802. One end of the slide rod 801 is connected to the cup lid 2, and the other end is a free end. The slide groove 802 is provided on the outer wall of the dust cup 1, and the slide rod 801 and the slide groove 802 are slidably connected.

[0082] During installation, the slide rod 801 is first inserted into the slide groove 802. Then, as the slide rod 801 slides along the slide groove 802, the cup lid 2 gradually approaches the dust cup 1 until the cup lid 2 is connected and assembled with the mouth of the dust cup 1. By setting a sliding limit mechanism, the accuracy of the assembly position of the cup lid 2 and the dust cup 1 can be improved, and the assembly efficiency can be increased.

[0083] In other embodiments, the slide bar 801 can also be provided on the dust cup 1, and correspondingly, the slide groove 802 is provided on the cup cover 2. Furthermore, the number of slide bars 801 and slide grooves 802 can be two or more.

[0084] In this embodiment, as Figure 3 and 5 As shown, the dust cup 1 and the cup lid 2 are fastened together by a locking structure. The locking structure includes an elastic locking component 901 and a locking engagement part 902, with one elastic locking component 901 and one locking engagement part 902.

[0085] A spring-loaded locking assembly 901 is disposed on one side of the cup lid 2. The spring-loaded locking assembly 901 includes an elastic element 9011 and a latch 9012. The length direction of the latch 9012 is perpendicular to the cup lid 2. The elastic element 9011 is a spring, with its two ends connected to one end of the cup lid 2 and one end of the latch 9012, respectively. The other end of the latch 9012 is provided with a hook. A locking engagement part 902 is disposed at the mouth of the dust cup 1, and engages with the hook of the latch 9012. By pressing the latch 9012, the latch 9012 compresses the spring, causing the hook of the latch 9012 to lock or unlock with the locking engagement part 902, facilitating the assembly and disassembly of the dust cup 1 and the cup lid 2 and improving assembly and disassembly efficiency.

[0086] In other embodiments, the elastic locking assembly 901 may also be disposed on the dust cup 1, the locking mating part 902 may be disposed on the cup lid 2, and the number of elastic locking assemblies 901 may also be two or three, etc.

[0087] According to an embodiment of the present invention, in another aspect, a cleaning device is also provided, such as... Figure 6 As shown, the device includes a dust-air separation device and a main unit 1001. The dust-air separation device is located on the upper part of the main unit 1001. A dust cup scraper assembly 3, connected to a cup lid 2, is installed inside the dust collection chamber 101 of the dust cup 1. The dust cup scraper assembly 3 can move along the dust collection chamber 101 with the cup lid 2. When cleaning dust and other dirt on the inner wall of the dust cup 1, the cup lid 2 is pulled outward in a direction away from the dust collection chamber 101. The cup lid 2 drives the dust cup scraper assembly 3 to move towards the opening of the dust cup 1 to scrape away the dust in the dust collection chamber 101, improving the cleaning efficiency and effect, and avoiding internal contamination and bacterial growth in the dust cup 1. A filter scraper assembly 4 is installed inside the cyclone chamber 102. This filter scraper assembly 4 can move relative to the separator assembly 5 installed inside the cyclone chamber 102, thereby scraping away the dust on the outer wall of the filter screen 502 of the separator assembly 5, preventing the filter screen 502 from clogging and facilitating use. In this embodiment, the cleaning device is a mite remover.

[0088] Of course, the mite remover in this embodiment also has other structures and components that are present in existing mite removers. Since this embodiment does not involve these structures and components, they will not be described in detail.

[0089] According to an embodiment of the present invention, in another aspect, a cleaning method is also provided, applied to the dust-gas separation device or cleaning device of the above embodiments, comprising the following steps:

[0090] When the dust collection chamber 101 needs to be cleaned, pull the cup cover 2 outward in a direction away from the dust collection chamber 101. The dust cup scraper assembly 3 moves with the cup cover 2 inside the dust collection chamber 101 to scrape off the dust on the inner wall of the dust collection chamber 101.

[0091] Specifically, such as Figure 7As shown, in this embodiment, when the dust collection chamber 101 needs to be cleaned, the cup lid 2 is removed. The cup lid 2 drives the scraper 301 to move outward along the dust collection chamber 101 via the connecting rod 302. While the scraper 301 moves, it scrapes off the dust on the inner wall of the dust collection chamber 101 and pulls it out of the dust collection chamber 101 to complete the cleaning of the dust collection chamber 101.

[0092] In other embodiments, when the dust collection chamber 101 needs to be cleaned, the cup cover 2 is removed and then rotated. The cup cover 2 drives the scraper 301 to rotate circumferentially along the inner wall of the dust collection chamber 101 through the connecting rod 302 and the mounting rod, so as to scrape off the dust on the inner wall of the dust collection chamber 101. Then, the dust in the dust collection chamber 101 is cleaned by tilting the dust cup 1, which facilitates the dust cleaning operation.

[0093] When the filter screen 502 needs to be cleaned, the dust cup 1 is removed from the motor air duct 7, and the filter screen scraping component 4 moves relative to the separator assembly 5 to scrape off the dust on the outer wall of the filter screen 502 on the separator assembly 5.

[0094] Specifically, such as Figure 8 As shown, after cleaning, when only the filter screen 502 needs to be cleaned, the dust cup 1 is removed from the motor air duct 7, and the scraper moves along the outer wall of the filter screen 502 to scrape off the dust on the filter screen 502, thus completing the cleaning of the filter screen 502.

[0095] The above-mentioned cleaning method can be used to clean the dust collection chamber 101 and the filter screen 502 separately according to the usage. The two cleaning processes are independent of each other and can be selected as needed, which is highly flexible and has a good cleaning effect.

[0096] In one embodiment, when it is necessary to clean the dust collection chamber 101 and the filter screen 502, the cup cover 2 is pulled outward in a direction away from the dust collection chamber 101. The dust cup scraping assembly 3 moves outward along the axial direction of the dust collection chamber 101 with the cup cover 2 to scrape off the dust on the inner wall of the dust collection chamber 101. Then, the cover is pulled outward. When the dust cup scraping assembly 3 is limited by the limiting structure, the cup cover 2 drives the dust cup 1 to disengage from the motor air duct 7. The filter screen scraping component 4 moves relative to the separator assembly 5 to scrape off the dust on the outer wall of the filter screen 502 on the separator assembly 5.

[0097] Specifically, such as Figure 9As shown, when cleaning both the dust collection chamber 101 and the filter screen 502 is required, the cup lid 2 is removed. The cup lid 2, via the connecting rod 302, drives the scraper 301 to move outward along the dust collection chamber 101. As the scraper 301 moves, it scrapes away the dust from the inner wall of the dust collection chamber 101 and pulls it out of the dust collection chamber 101. When the scraper 301 is pulled to the cup opening, it is blocked by the baffle at the cup opening. Then, the cup lid 2 continues to be pulled away from the dust cup 1 until the dust cup 1 is detached from the motor air duct 7. At this time, during the process of the dust cup 1 detaching from the motor air duct 7, the scraper moves along the outer wall of the filter screen 502, scraping off the dust on the filter screen 502 to complete the cleaning of the dust collection chamber 101 and the filter screen 502.

[0098] The cleaning method described above allows for simultaneous cleaning of the filter screen 502 while cleaning the dust collection chamber 101. This achieves a coordinated cleaning process between the inner wall of the dust collection chamber 101 and the outer wall of the filter screen 502. The cleaning is sequential: first, the inner wall of the dust collection chamber 101 is cleaned, and then the outer wall of the filter screen 502 is cleaned. This cleaning method is more efficient, convenient, flexible, meets diverse usage needs, and enhances the user experience.

[0099] In other words, when both the dust collection chamber 101 and the filter screen 502 need to be cleaned, the user can choose to clean the dust collection chamber 101 and the filter screen 502 separately, or they can choose to clean the dust collection chamber 101 and the filter screen 502 together using the method of this embodiment. This provides high flexibility and multiple operation options for users to meet different usage needs.

[0100] In other embodiments, the cleaning device may also be a vacuum cleaner, a robotic vacuum cleaner, a window cleaning robot, etc. The dust-air separation device of the present invention is applicable to a variety of vacuum cleaning devices and has strong applicability.

[0101] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
