[0004] The present application relates to the technical field of cleaning equipment, in particular a cleaning device. STATE OF THE ART

[0005] With improving material living standards, people have increasingly higher expectations for their home environment. Vacuum cleaners are becoming increasingly common due to their ease of use and operation. Vacuum cleaners rely on a fan to create negative pressure within the vacuuming channel, drawing in dust, dirt, and air. The dust and dirt are collected by a filter system, and the air is then expelled by the fan.

[0006] In conventional vacuum cleaners, a significant amount of dust and dirt accumulates on the filter of the separating structure during use. If it is not cleaned for an extended period, the filter screen can easily become clogged, reducing suction power and making it difficult to remove the dirt. It is necessary to disassemble the dust container lid and remove the filter. Frequent disassembly can compromise the seal between the parts, negatively impacting the vacuum cleaner's lifespan and dust removal efficiency. CONTENT OF THE PRESENT APPLICATION

DETAILED DESCRIPTION

[0054] Embodiments of the present application are described in more detail below, and examples of such embodiments are illustrated in the accompanying drawings, where the same or similar reference numerals everywhere denote the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to serve to clarify the present application and should not be construed as limiting the present application.

[0055] Combined with Fig. 1 to Fig. According to the embodiments of the present application, the cleaning device 100 comprises a main body 10, a dust cup 11, an air inlet tube 18, and a dust scraper. The main body 10 includes a first filter 12, the dust cup 11 comprises a cup body 111 and a cup cover 112, and the cup body 111 is connected to the main body 10. In particular, the first filter 12 can separate the dust-containing gas in the cleaning device 100 into dust and gas. The dust cup 11 is enclosed on the outside of the first filter 12 to collect the dust collected by the first filter 12. One end of the cup body 111 is provided with a dust discharge opening, the cup cover 112 covers the dust discharge opening and can be opened, the dust in the cup body 111 can be discharged through the dust discharge opening, and the dust in the cup body 111 can be cleaned.In particular, the air inlet pipe 18 and the cup body 111 are arranged side by side and extend in the same direction, which can be advantageous for the spatial arrangement and improve the compactness of the device structure. At least part of the dust scraper is encased on the outside of the first filter 12 and is suitable for moving along an axial direction of the first filter 12, thereby scraping the dust off the outside of the first filter 12 to prevent clogging, achieve a cleaning effect, improve the performance of the first filter 12, and facilitate dust collection.In particular, the directions of extension of the cup body 111, the first filter 12, the dust scraper and the air inlet tube 18 are the same, which is advantageous on the one hand for reducing the size of the cleaning device 100 and for facilitating the spatial arrangement, and on the other hand the air inlet tube 18 can be arranged on the outer circumferential wall of the cup body 111 and extend along the axial direction of the cup body 111, so that the airflow after entering the cup body 111 can flow out of the air inlet tube 18 in a spiral, which is advantageous for improving the separation effect, and the dust scraper can scrape the separated dust from the first filter 12, thereby improving the cleaning effect and facilitating dust collection and cleaning.

[0056] According to the cleaning device 100 of the embodiment of the present application, the provision of the dust scraper makes it possible to facilitate the cleaning of the filter, improve the cleaning effect of the first filter 12 and offer convenience to the user.

[0057] During actual use, dust and dirt constantly accumulate on the first filter 12 of the cleaning device 100 during the cleaning process. If the dust and dirt are not removed for an extended period, the filter can become easily clogged, reducing the filter's effectiveness or the suction power. Therefore, during use, the dust scraper can be driven into motion, allowing it to move along the outside of the first filter 12 to scrape the dust and dirt from the filter's outer surface. The scraped-off dust and dirt can then be collected directly in the collection cup 111. The dust scraper can be driven manually, automatically, or electrically. For example, the user can move the dust scraper manually to remove the dust or press a button to activate the automatic operation.It is also possible that a detection device is arranged in the dust cup. If there is a lot of dust on the first filter 12, the dust scraper is automatically started or the user is prompted to clean the first filter 12, etc. The present application is not limited to this.

[0058] For example, the user can feel that if a lot of dust accumulates on the outside of the first filter 12, the dust scraper will encounter resistance when moving. As the cleaning progresses, the dust on the outside of the first filter 12 is cleaned, and the dust scraper's movement gradually becomes smoother. The user can confirm the cleaning effect by feeling the changes in the hand during the cleaning process.

[0059] Combined with Fig. 2 and Fig. In some embodiments of the present application, the cleaning device 100 further comprises a dust scraping section 20 and an operating section 30. In particular, the dust scraping section 20 is enclosed on the outer circumferential surface of the first filter 12 and is capable of moving back and forth along the axial direction of the first filter 12 to scrape off dust from the outside of the first filter 12. This improves the dust scraping effect and requires less space, thus promoting efficient room design. The operating section 30 is connected to the dust scraping section 20 by means of a transmission and is used to drive the dust scraping section 20 for movement. The operating section 30 is also configured to drive the cup cover 112 for opening.In other words, the operating section 30 can both drive the dust scraper to move in order to clean the first filter 12, and can also be designed to open the cup cover 112. The user does not need to open the cover manually, which can prevent dust and secondary contamination and offer the user convenience.

[0060] In the prior art, the user must hold the cleaning device with one hand and open the cover with the other, which easily generates dust and is inconvenient to operate. According to the cleaning device 100 of the embodiment of the present application, a significant amount of dust accumulates in the cup body 111 after prolonged use. When cleaning is required, the cup cover 112 can be driven to open by controlling the operating section 30, which facilitates the cleaning of the dust from the cup body 111. Therefore, during cleaning, the user can operate the device with one hand to drive the operating section 30 to open automatically, providing convenience. When cleaning the cup body 111, the dust discharge opening can be pre-aligned with a dust collection device or a dust bag.When the operating section 30 drives the cup cover 112 to open, the dust in the cup body 111 can go directly into the dust collection device or the garbage bag to avoid dust overflow.

[0061] Combined with Fig. 5 The dust scraping section 20 comprises in particular a holder and a ring section, the holder and the ring section are connected in the axial direction, the ring section is connected to the inside of the holder and the ring section gradually shrinks radially inwards to facilitate contact with the outside of the first filter 12 and to improve the dust scraping effect.

[0062] Further in connection with Fig. 3 and Fig. In some embodiments of the present application, the cleaning device 100 further comprises a connecting rod 50, and the two ends of the connecting rod 50 are each connected to the dust scraping section 20 and the operating section 30, such that the operating section 30 is connected to the dust scraping section by transmission. In other words, the connecting rod 50 can transmit the force of the operating section 30 to the guide rod 21, thereby driving the dust scraping section 20 into motion. By adjusting the connecting rod 50, the position of the operating section 30 can be flexibly arranged, which is user-friendly and convenient for spatial arrangement. Optionally, the connecting rod 50 can also be connected to the support section 23, and the operating section 30 is connected to the support section 23 by transmission. The movement of the support section 23 can drive the movement of the dust scraping section 20.In particular, the connecting rod can comprise a first rod section and a second rod section, one end of the first rod section being connected to the guide rod 21 and extending in the same direction as the guide rod 21, the other end of the first rod section being connected to one end of the second rod section and the other end of the second rod section being connected to the operating section 30, wherein the first rod section and the second rod section have an angle between the rods at the connection or an angle between the lines of extension in their directions of extension, thereby allowing the setting position of the operating section 30 to be arranged flexibly.

[0063] Further in connection with Fig. 3 and Fig. 5 In some embodiments of the present application, the dust scraper further comprises a guide rod 21 and a support section 23. The support section 23 is connected to the dust scraper section 20 via the guide rod 21 and can support the dust scraper section 20 in the axial direction to prevent shaking of the dust scraper section 20 during movement, thereby improving the structural and operational stability of the dust scraper section 20. In this way, if large dirt adheres to the outside of the first filter 12, the dust scraper section 20 can also scrape it off, which is advantageous for improving the cleaning effect and durability. The guide rod 21 extends in the axial direction and is connected to the dust scraper section 20 at one end. The support section 23 is connected to the other end of the guide rod 21 and is movably mounted on the main body 10.The guide rod 21 extends in the axial direction and can guide the dust scraper section 20 in axial movement. The guide rod 21 can also act as a support roller between the support section 23 and the dust scraper section 20, which is advantageous for distributing the force.

[0064] Combined with Fig. 2 and Fig. 3 In some embodiments of the present application, the main body 10 further comprises a motor housing 16, a space for receiving the motor 40 is formed in the motor housing 16, the motor housing 16 and the first filter 12 are arranged axially, and the support section 23 is enclosed on the outside of the motor housing 16. In particular, the support section 23 can be arranged between the motor housing 16 and the outer shell of the cleaning device 100, which is suitable for receiving the support section 23, and the support section 23 can move axially along the motor housing 16. When the support section 23 moves, the dust scraper section 20 can also move axially outside the first filter 12.

[0065] Combined with Fig. 3 In some embodiments of the present application, the main body 10 further comprises a guide section 60, which is arranged between the support section 23 and the dust scraper section 20. The guide section 60 is provided with a guide hole for the passage of the guide rod 21 and guides the guide rod 21 for axial movement, so that the dust scraper section can extend axially along the main body 10, which can save space and improve the compactness of the device. In addition, the guide section 60 can limit the guide rod 21 in the radial direction to prevent the dust scraper from shaking during use.

[0066] Combined with Fig. 3 In some embodiments of the present application, the dust scraper further comprises a spring 24 which is enclosed on the guide rod 21, and the two ends of the spring 24 bear against the guide section 60 and the support section 23, respectively. The spring 24 is designed to exert a force to move the dust scraper in one direction away from the cup cover 112 in order to provide a restoring force for the dust scraper section 20, so that the dust scraper section 20 is automatically resettable, which is convenient for the user. In use, the operating section 30 can drive the dust scraper to move in one direction near the cup cover 112 to scrape the dust through the outside of the first filter 12. Meanwhile, the support section 23 also moves in one direction near the cup cover 112 or the guide section 60, and the spring 24 bears against and is compressed between the support section 23 and the guide section 60.When the driving force disappears, the restoring force of the spring 24 can drive the support section 23 and the dust scraper section 20 to return to their original position, in order to simplify operation.

[0067] Combined with Fig. 2 and Fig. In some embodiments of the present application, the operating section 30 is configured to actuate the cup cover 112 for opening. The dust cup 11 further comprises a locking section 14, one side of the cup cover 112 is hinged to the cup body 111, and the other side of the cup cover 112 is locked to the cup body 111 by the locking section 14. The operating section 30 comprises a connecting section 31, and the connecting section 31 is designed to engage with the locking section 14 to open the cup cover 112, thus enabling automatic opening of the cover and avoiding manual operation.In particular, the locking section 14 can lock the cup cover 112 when the cup cover 112 closes the dust pouring opening; and when the cover needs to be opened, the operating section 30 rests against the locking section 14 to enable the unlocking of the locking section 14, and the locking section 14 can release the cup cover 112, thereby connecting one side of the cup cover 112 to the cup body 111 and separating the other side of the cup cover 112 from the cup body 111, so that the dust pouring opening can be open.

[0068] Combined with Fig. In some embodiments of the present application, the locking section 14 is rotatably connected to the dust cup 11. The locking section 14 has a trigger end 141 and a locking hook 142. The locking hook 142 is hooked onto the cup cover 112. The attachment section 31 is designed to bear against the trigger end 141 to enable the locking hook 142 to unlock the cup cover 112. In particular, the locking hook 142 has a locked state and an unlocked state. The locking hook 142 can be configured to lock the cup cover 112 in the locked state.The trigger end 141 is connected to the locking hook 142 by transmission, so that the trigger end 141 can control the state of the locking hook 142, and the locking hook 142 can be adjusted from the locked state to the unlocked state, so that the locking hook 142 triggers the cup cover 112.

[0069] Combined with Fig. 1 and Fig. 3 In some embodiments of the present application, the dust scraper has a first position, a second position, and a third position in the axial direction. The distance from the dust scraper to the cup cover 112 gradually decreases in the first, second, and third positions, and in the third position, the dust scraper drives the cup cover 112 to open. That is, the operating section 30 can drive the dust scraper to move from the first position to the third position, thereby achieving the effects of dust scraping and opening the cover.Since, for example, the first filter 12 is arranged in the cup body 111 and the cup cover 112 is arranged at the end of the cup body 111, when the operating section 30 controls the dust scraper to move between the first position and the second position, the dust scraper passes through the outside of the first filter 12 and performs a dust scraping action; when the operating section 30 controls the dust scraper to gradually move into the third position, it gradually approaches the cup cover 112 so that the operating section 30 can abut the locking section 14.Furthermore, by setting the third position, where the third position is closer to the cup cover 112 than the second position, the system section 31 and the locking section 14 are located at a certain distance during the dust scraping process, which can prevent the operating section 30 from being accidentally touched by the user during the dust scraping process and the cup cover 112 from being opened, thus improving operational safety.

[0070] Furthermore, the dust scraper is designed such that the damping from the first position to the second position is less than the damping from the second position to the third position, allowing the user to easily scrape off the dust and easily identify the control state of the operating section 30. Specifically, the dust scraper exhibits low damping when moving between the first and second positions, enabling the user to control the operating section 30 with minimal force. Conversely, the dust scraper exhibits high damping when moving from the second to the third position, requiring a certain amount of force to control the operating section 30 during manual operation to open the cup cover 112. This prevents accidental contact and opening of the cover.And due to the different damping levels, the user can also be given a prompt, and the user can determine the position and condition of the dust scraper according to different hand sensitivities.

[0071] Naturally, a limiting structure can be provided between the second and third positions, and the operating section 30 must pass over the limiting structure to engage the locking section 14. This allows for operational feedback to be provided to the user and improves the usability.

[0072] In some embodiments of the present application, the cleaning device 100 further comprises a damping structure configured to provide damping for the movement of the operating section 30 from the second position to the third position. That is, no damping effect occurs when the operating section 30 moves between the first position and the second position, so that the user can more easily drive the duster to move between the first and second positions; when the operating section 30 moves from the second position to the third position, the damping force must be overcome.When the operating section 30 reaches the third position, the system section 31 can trigger the locking section 14 to open the cup cover 112, which can prevent the cup cover 112 from being opened due to operator error, and can also provide a tactile feedback that can differentiate the operating state of the operating section 30, making it convenient for the user to determine the working state of the dust scraper.

[0073] The first position and the second position are arranged at opposite ends of the axial direction of the first filter 12, so that the dust scraper can scrape the dust off the outside of the first filter 12 as it moves between the first position and the second position.

[0074] Combined with Fig. 1 In some embodiments of the present application, the main body 10 comprises a shell, the dust scraping section 20 is arranged in the shell, the shell is provided with a slide rail 102, the slide rail 102 extends axially, the operating section 30 cooperates in an axially slidable manner with the slide rail 102 and the operating section 30 can slide in the slide rail 102 to limit the sliding area of ​​the operating section 30, which is advantageous for improving operational stability.

[0075] Combined with Fig. 1 In some embodiments of the present application, the operating section 30 is U-shaped and encased around the air inlet pipe 18, so that the operating section 30 can surround part of the air inlet pipe 18, which contributes to improving the stability of the interaction. Both ends of the operating section 30 are connected to the shell and can slid together, which improves the stability of the connection between the operating section 30 and the shell and simultaneously contributes to improving the stability of the operating section 30 during sliding.

[0076] Combined with Fig. In some embodiments of the present application, the main body 10 further comprises a handle 71, a support element 72, and a power supply assembly 73. The power supply assembly 73 extends axially, the support element 72 and the handle 71 are arranged axially opposite and spaced apart, the support element 72 is connected to the air inlet tube 18 and the power supply assembly 73 respectively, and the handle 71 is connected to the shell and the power supply assembly 73 respectively, which can improve structural stability. In particular, the power supply assembly 73 can be used to support the main body 10, and when the cleaning device 100 is placed, the power supply assembly 73 is stored on a table for easy storage.The handle 71 is connected between the power supply assembly 73 and the main body 10, which not only provides support but also allows the user to place their hand in the space between the power supply assembly 73 and the main body 10. This makes it easy to hold the cleaning device 100 and perform a smooth cleaning motion. Furthermore, when using the dust scraper, the user can directly pull forward the operating section 30, which is connected to the air inlet tube 18, with their finger, allowing for one-handed operation and thus providing convenience.

[0077] Combined with Fig. 2. A battery is also provided in the power supply assembly 73 to provide a housing for the battery, so that when the power supply is switched off, the user can use the battery energy to power the cleaning device 100. Placing the battery in the power supply assembly 73 is also advantageous for improving the stability of the power supply assembly 73, as it lowers the center of gravity of the cleaning device 100, thus promoting stable placement.

[0078] Combined with Fig. In some embodiments of the present application, the inlet 108 of the air inlet tube 18 and the dust collection opening of the cup body 111 point in the same direction, which is advantageous for improving the cleaning effect of the cleaning device 100. Generally, when used by the user, the inlet 108 is aligned with the surface to be cleaned, so that the surface to be cleaned rests against the inlet 108 to improve the cleaning effect. When this side of the cleaning device 100 touches the surface to be cleaned, a better fit between the cleaning device 100 and the surface to be cleaned can be achieved, and it is also easier for the user to move, which is convenient for the user and advantageous for improving the dust collection effect.

[0079] Combined with Fig. 3 In some embodiments of the present application, the main body 10 further comprises a second filter 13. The second filter 13 extends axially, and one end of the second filter 13 is provided with a handle 131. The handle 131 is located at an end facing away from the cup cover 112 and is designed to pass through the cup cover 112. It is detachably sealed to the cup cover 112. In this way, the user can pull the second filter 13 out axially through the handle 131 and clean the second filter 13 without opening the cup cover 112 of the dust cup 11. This is convenient for cleaning and installing the second filter 13 and offers user comfort. In particular, the second filter 13 is located in the front part of the motor 40 on an airflow path.During operation, the airflow first passes through the second filter 13 for filtration and then flows to the motor 40, which is advantageous for improving the cleaning effect and protecting the motor 40. Therefore, to improve the filtration effect and make it easier for the user to quickly remove and clean the second filter 13, a handle 131 can be provided on the second filter 13, which interacts with the dust cup 11 to improve assembly efficiency. During operation, the second filter 13 can be inserted into the main body 10, and the main body 10 is provided with a clamping section, which improves the stability of the installation of the second filter 13. A sealing ring is provided between the second filter 13, the main body 10, and the cup cover 112 for sealing.Alternatively, after inserting the second filter 13, the second filter 13 can be rotated to find a docking section, and the filter 13 will be against the docking section or clamped to the docking section.

[0080] Furthermore, the main body 10 also includes a third filter 15, which is located in the airflow path downstream of the motor 40. During operation, the airflow leads to the motor 40 and is then discharged through the third filter 15, which is advantageous for improving the purity of the specified gas and preventing secondary contamination.

[0081] A cleaning device according to a specific embodiment of the present application is described below with reference to the attached drawings.

[0082] Combined with Fig. 1 to Fig. According to the embodiments of the present application, the cleaning device 100 comprises a main body 10, a dust cup 11 connected to the main body 10, a handle 71, a motor 40, a power supply assembly 73, an air inlet tube 18, a first filter 12, a second filter 13, and a third filter 15 connected to the motor 40. In this embodiment, the cleaning device 100 has a lateral air inlet, such that the inlet 108 is located on one side of the dust cup 11. The second filter 13 and the third filter 15 are located upstream and downstream of the motor 40, respectively, along the airflow path for filtering the airflow, and the third filter 15 may overlap with the motor 40 depending on the prevailing conditions in the room.The dust cup 11, the motor 40, and the third filter 15 are arranged sequentially along the longitudinal axis of the dust cup 11, and the second filter 13 is located inside the dust cup 11. The power supply assembly 73 is located at the bottom of the cleaning device 100 and can support the entire device. The handle 71 is located between the motor 40 and the power supply assembly 73. The axis of the handle 71 does not pass through the motor 40. The motor 40 is positioned further back relative to the axis of the handle 71, and the center of gravity is also located further back to prevent the user's wrist from exerting additional force during use, thus improving ergonomics. The cleaning device 100 has a distal end and a proximal end, which are arranged opposite each other. The inlet 108 is located at the distal end, and the third filter 15 is located at the proximal end.Combined with . Fig. 2. The distal end can be the anterior end and the proximal end the posterior end.

[0083] The dust cup 11 comprises a cup body 111 and a cup cover 112 for pouring dust. The first filter 12 is arranged in the cup body 111, and the first filter 12 can be a filter mesh covering with multiple through-holes on its surface for filtering dust with larger particle sizes. A multi-cone cyclone can also be provided in the dust cup 11. The multi-cone cyclone comprises several small cones arranged circumferentially in the dust cup 11 and downstream of the first filter 12 to perform further filtration and improve the filtering effect. The dust cup 11 is further provided with a locking section 14 for locking and unlocking the cup cover 112.

[0084] Combined with Fig. 3 The cleaning device 100 further comprises a dust scraper, which includes an operating section 30, a connecting rod 50 connected to the operating section 30, a support section 23 fixed in the main body 10, and a dust scraper section 20 connected to the support section 23. The dust scraper section 20 rests against the outer wall of the first filter 12 and is located in its initial position at an end of the first filter 12 facing the motor 40.

[0085] In particular, three guide rods 21 are arranged at intervals between the support section 23 and the dust scraper section 20 to transmit the movement of the operating section 30. One end of the connecting rod 50 is connected to the operating section 30, and the other end of the connecting rod 50 is connected to at least one of the guide rods 21 to drive the dust scraper section 20 to move when the connecting rod 50 moves. The support section 23 is arranged around the periphery of the engine hood 16 and can move along the engine hood 16 when the operating section 30 is pushed. Since the dust scraper section 20 is connected to the support section 23 via the guide rod 21, the dust scraper section 20 moves in the same direction as the support section 23 moves along the engine hood 16, scraping the dust from the periphery of the first filter 12.

[0086] Furthermore, a spring 24 is encased on the guide rod 21. When dust is scraped off, the movement of the support section 23 causes the spring 24 to compress. After dust scraping is complete, the dust scraper section 20 automatically returns to its original position due to the restoring force of the spring 24. The operating section 30 is located below the dust cup 11. This position makes pushing and pulling more convenient for the user, resulting in smoother operation.

[0087] According to the cleaning device 100 of the embodiment of the present application, the dust cup 11 does not move during the dust scraping process, and only the dust scraping section 20 moves within the dust cup 11. The principle of dust scraping is as follows: During the dust scraping process, the user pushes the operating section 30, and the operating section 30 drives the connecting rod 50 into motion. The movement of the connecting rod 50 drives the support section 23 to move along the periphery of the hood 16, and the movement of the support section 23 drives the dust scraping section 20 to contact the periphery of the first filter 12 in order to scrape off dust. At this point, the spring 24 is compressed, and the push-and-pull action of the dust scraping can be repeated several times. By repeatedly moving the dust scraping section 20, the dust on the outside of the first filter 12 can be scraped off more thoroughly.At the end of the dust scraping process, the operating section 30 returns to its starting position under the action of the elastic restoring force of the spring 24, and then drives the dust scraper section 20 to move into its starting position. By adjusting the dust scraper, the dust and dirt accumulated on the first filter 12 can be scraped off each time the dust is poured, and regular cleaning is carried out to prevent the filter mesh from clogging and affecting the suction power of the cleaning device 100. There is no need to disassemble the dust cup 11. Operation is simple and convenient, and the dust removal effect is good.

[0088] Furthermore, the dust scraper has no connection or interaction with the outer or inner wall of the dust cup 11, and the inner wall of the entire dust cup 11 is a complete annular wall. This arrangement ensures the continuity of the airflow within the dust cup 11 and prevents disturbances in the airflow.

[0089] Furthermore, the operating section 30 also includes a system section 31 located at the end of the connecting rod 50 opposite the operating section 30. When the dust scraper section 20 moves to or near the end of its stroke (third position), the system section 31 presses the locking section 14 of the dust cup 11 to unlock it, causing the cup cover 112 to open. After or during the dust scraping process, the cup cover 112 opens to allow for scraping and dust pouring. At this point, the user will be working facing the waste container. Because the dust cup 11 is positioned horizontally in the structural form of the present application, the waste is poured directly from the front end of the dust cup 11 into the waste container, preventing dust from overflowing or falling back onto the clean floor.At the same time, the user only needs to push the operating section 30 and not touch the area around the cup cover 112, thus avoiding contact with dust and improving the user experience.

[0090] The airflow path of the entire device during actual use is as follows: The airflow enters the air inlet pipe 18 from the inlet 108. Dust and air enter the dust cup 11 from the side of the dust cup 11, and the dust, after being filtered through the first filter 12, falls into a first dust collection chamber. The airflow, containing a small amount of dust, then enters the multi-cone cyclone for further filtration, and the filtered fine dust falls into a second dust collection chamber. The airflow then enters the second filter 13 for further filtration and flows towards the motor 40, finally passing through the third filter 15 and being discharged from the outlet 109.

[0091] Specifically, dust and air enter the cleaning device tangentially through an intake opening and travel along the air duct. Under the influence of centrifugal force, the dust and debris rotate along the wall of the dust cup 11 towards the first dust collection chamber of the dust cup 11. A crimp at a certain angle to the horizontal direction is positioned beneath the filter mesh cover. This crimp prevents dust, which enters the base due to centrifugal force, from re-entering the multi-cone cyclone, thus effectively reducing the total amount of dust entering the multi-cone cyclone. Some of the dust passes through the filter mesh cover and enters the multi-cone cyclone. Similarly, under the influence of centrifugal force, the dust rotates along the wall of the multi-cone cyclone towards the second dust collection chamber at the base.At the dust-gas separation opening, the gas passes through the porous air passage into the second filter 13 and then into the motor 40, where it is subsequently filtered through the third filter 15 and discharged. In this case, by using two cyclone filters and a multi-cone cyclone mechanism for secondary filtration, the separation efficiency of dust and air can be significantly increased, the number of times the filter needs to be cleaned reduced, and the filter's service life extended.

[0092] The second filter 13 is located inside the first filter 12. A handle 131 is provided at the end of the second filter 13, which is used to remove the second filter 13 along the longitudinal axis of the dust cup 11. The handle 131 of the second filter 13 is located near the cup cover 112, and the second filter 13 is removed in a direction away from the cup cover 112. The third filter 15 can be removed backwards, and this arrangement facilitates cleaning of the second filter 13 and the third filter 15. The second filter 13 is arranged coaxially with the first filter 12. The second filter 13 comprises filter cotton and a filter holder. After filtering through the filter cotton, the airflow passes through a multitude of through-holes in the filter holder into the interior and flows from the inner duct to the motor 40.As mentioned above, the second filter 13 is located in the center of the dust cup 11 and connected to the fan assembly via a sealing ring at the top, allowing for quick disassembly and cleaning. After dust and gas separation, the gas enters the second filter 13 through the porous air passage, enters the motor 40, and is then discharged. A small amount of fine ash typically adheres to the outer wall of the second filter 13. When the second filter 13 needs cleaning, the handle 131 of the second filter 13 can be grasped by hand at the hole at the bottom of the dust cup 11 and pulled outwards. After cleaning, reassembly can be carried out in the same way. In this way, the second filter 13 can be quickly cleaned or replaced without disassembling other components, significantly improving user convenience and satisfaction.

[0093] A power switch is provided above the handle 71, located on the shell or at the screen location. The cleaning device 100 is further equipped with a rear end cover, and a rear-facing display screen is provided on the rear end cover. During disassembly, the rear end cover is removed first, followed by the third filter 15 for cleaning.

[0094] In combination with Fig. 1 to Fig. According to the embodiment of the present application, the cleaning device 100 comprises a main body 10 and a dust cup 11. The main body 10 has a first filter 12. The first filter 12 can separate the dust-containing gas in the cleaning device 100 into dust and gas. The dust cup 11 is connected to the main body 10. The dust cup 11 is enclosed on the outside of the first filter 12, so that the dust cup 11 can be used to collect dust generated after filtering through the first filter 12.

[0095] Furthermore, the dust generated by the filtration of the first filter 12 is distributed into the space formed between the first filter 12 and the dust cup 11. Since the first filter 12 can filter out somewhat lighter dust, the dust is distributed in clumps between the dust cup 11 and the first filter 12. This means that the dust not only easily clogs the first filter 12 and impairs the vacuuming effect, but also adheres to the wall of the dust cup 11 during cleaning and cannot be emptied; or, if emptied by the user, creates a dust cloud and causes secondary contamination. Therefore, the cleaning device 100 is further equipped with a dust scraper, which serves to push the dust between the first filter 12 and the dust cup 11 to facilitate dust collection.In particular, the dust scraper has a dust scraper section 20, which is arranged between the dust cup 11 and the first filter 12, and a dust compression chamber 101 is formed between the dust scraper section 20 and a bottom wall of the dust cup 11. The dust scraper section 20 covers one end of the dust compression chamber 101 and is movable along the axis of the first filter 12. That is, the dust scraper section 20 can move within the dust compression chamber 101. During the movement of the dust scraper section 20, the scattered, flaky dust in the dust compression chamber 101 can be collected at one end of the dust compression chamber 101. In this way, it can be prevented that the flaky or lighter dust affects the operation of the first filter 12.After the dust is compressed by the dust scraper section 20, the dust scattered in the dust compaction chamber 101 is compressed, which reduces the space occupied by dust in the dust compaction chamber 101 and contributes to increasing the dust collection capacity of the dust cup 11. In this way, the user does not have to empty the dust in the dust cup 11 frequently, which can shorten cleaning time and offer the user convenience. In addition, the dust scraper can also improve the cleanliness in the dust cup 11 during the collection and compression of the dust and prevent the occurrence of dust clouds or dust spraying when cleaning or opening the dust cup 11 by the user.

[0096] According to the cleaning device 100 of the embodiment of the present application, by placing the dust scraper between the first filter 12 and the dust cup 11, the dust in the dust cup 11 can be collected and compressed, which is advantageous to improve the cleaning effect of the dust cup 11 and to avoid the problem of dust spraying or dust cloud when opening the dust cup 11, thereby avoiding secondary contamination and facilitating user use.

[0097] Combined with Fig. 3 and Fig. In some embodiments of the present application, the dust scraping section 20 is enclosed on the outside of the first filter 12, and the dust scraping section 20 has a squeezing element 25 extending towards and adjacent to the inner wall of the dust cup 11, which is capable of moving along the axial direction of the first filter 12 to compress the dust in the dust compression chamber 101. In other words, the squeezing element 25 can extend from the outside of the first filter 12 into a position adjacent to the inner wall of the dust cup 11, which promotes the enlargement of the dust compression chamber 101, facilitates the compression of more dust, and improves the dust collection and compression effect.In particular, if the distance between the compression element 25 and the inner wall of the dust cup 11 is reduced, the cleaning effect of the compression element 25 on the dust located near the inner wall of the dust cup 11 and on the dust adhering to the inner wall of the dust cup 11 can be improved, and the dust cup 11 can be cleaned during dust compression, thereby reducing the work required to clean the dust cup 11 by the user. Naturally, the size of the compression element 25 can also be adjusted according to the current situation based on the size of the first filter 12 or the dust cup 11, or the current application scenario, etc., and the present application is not limited to this.

[0098] Combined with Fig. 5 In some embodiments of the present application, the crushing element 25 has a first side wall and a second side wall arranged opposite each other in the radial direction. The first side wall and the outer surface of the first filter 12 are arranged opposite each other in the radial direction of the first filter 12, and the second side wall and the inner wall of the dust cup 11 are arranged opposite each other in the radial direction of the first filter 12. In particular, the crushing element 25 can have a shape with a certain thickness in the axial direction of the first filter 12, so that the structural and operational stability of the crushing element 25 is improved, the crushing effect of the crushing element 25 on the dust is improved, and the dust can be compacted.In addition, the contact area where the squeezing element 25 interacts with the first filter 12 or the inner wall of the dust cup 11 can also be enlarged to improve the cleaning effect.

[0099] Combined with Fig. 3 to Fig. 6, in some embodiments of the present application, a dust scraper element 22 is connected to the first side wall. The dust scraper element 22 extends along the axial direction of the first filter 12 and is suitable for clearance fitting with the outside of the first filter 12.

[0100] In particular, the dust scraper element 22 is encased on the outer circumferential surface of the first filter 12 and is designed to move back and forth along the axial direction of the first filter 12 to scrape dust. It serves to scrape dust from the outside of the first filter 12, which can improve the cleaning effect of the first filter 12. The dust scraper element 22 is integrated into the dust scraper, which takes up less space and is advantageous for spatial arrangement. In other words, the dust scraper section 20 can clean the outer surface of the first filter 12 to prevent dust from adhering to the outside of the first filter 12 and affecting the filtering effect or the cleaning effect of the cleaning device 100. Simultaneously, the dust scraper section 20 can also collect dust in the dust compaction chamber 101.In particular, when the dust scraper section 20 is working, after the dust scraper element 22 has scraped the dust off the outside of the first filter 12, the dust falls into the dust compression chamber 101 and can be collected and compressed directly by the squeezing element 25, which further improves the cleaning effect and enhances the functionality of the dust scraper.

[0101] In some embodiments of the present application, the first side wall is in a clearance fit with the outer surface of the first filter 12; that is, a clearance fit (including a minimum clearance of zero) can exist between the first side wall and the outer surface of the first filter 12. The clearance between the first side wall and the outer surface of the first filter 12 can improve the movement flexibility of the squeezing element 25 and facilitate its use.

[0102] Combined with Fig. 6. If the clearance between the first side wall and the first filter 12 is small or zero, the fit between the first side wall or the dust scraper element 22 on the first side wall and the first filter 12 can be improved, which is conducive to cleaning the first filter 12. The dust scraper element 22 can be integrated into the first side wall, or the dust scraper element 22 and the first side wall can be formed as one piece, etc., and the present application is not limited to this.

[0103] In some embodiments of the present application, the second side wall and the inner wall of the dust cup 11 are in clearance fit, i.e., a clearance fit (including a minimum clearance of zero) can exist between the second side wall and the inner wall of the dust cup 11. If there is clearance between the second side wall and the inner wall of the dust cup 11, the movement flexibility of the squeezing element 25 can be improved, which is convenient for the user. If the clearance between the second side wall and the inner wall of the dust cup 11 is small or zero, the fit between the second side wall and the inner wall of the dust cup 11 can be improved, and the inner wall of the dust cup 11 can be cleaned during dust pressing and squeezing.

[0104] In some embodiments of the present application, the dust scraper section 20 is a flexible structure and / or has bristles (not shown), which protects the components in the cleaning device 100, improves flexibility during movement or use, and also enhances the cleaning effect. The bristles can be arranged towards the inner wall of the dust cup 11 to clean the inner wall of the dust cup 11 during movement of the dust scraper section 20, thereby improving the cleaning effect of the dust cup 11. For example, the dust scraper section 20 can be a soft rubber band or an annular soft rubber band to reduce the weight and flexibility of the dust scraper section 20.In actual use, since the dust scraper section 20 is in contact with dust for a long time and is easily contaminated, the soft rubber band is easy to replace and buy, and the user can also replace the rubber band after use for a period of time to improve the cleanliness of the device.

[0105] The dust scraper section 20 can also have bristles that may be arranged on one side facing the inner wall of the dust cup 11, so that when the dust scraper section 20 is moved, the inner wall of the dust cup 11 is cleaned and the dust adhering to the inner wall of the dust cup 11 can be removed. The dust is then squeezed by the squeezing element 25 to improve the cleaning effect of the dust in the dust cup 11 and enhance the automatic cleaning action of the dust cup 11. Therefore, when the user cleans the dust cup 11, the dust in the dust cup 11 is squeezed into blocks that can be poured out directly, and the squeezed dust is not lifted up during pouring to prevent secondary contamination. At the same time, the dust scraper section 20 also cleans the inner wall of the dust cup 11, which makes cleaning the dust cup 11 easier for the user.

[0106] In combination with Fig. 2 and Fig. 5 In some embodiments of the present application, the dust scraper comprises an operating section 30 which is connected to the dust scraper section 20 by transmission and serves to drive the dust scraper section 20 to movement.

[0107] And at least part of the operating section 30 is located outside the dust cup 11 for manual operation.

[0108] Combined with Fig. 4 and Fig. In some embodiments of the present application, the cleaning device 100 further comprises a connecting rod 50, and the two ends of the connecting rod 50 are each connected to the dust scraping section 20 and the operating section 30, such that the operating section 30 is connected to the dust scraping section 20 by transmission. In other words, the connecting rod 50 can transmit the force of the operating section 30 to the guide rod 21, thereby driving the dust scraping section 20 to movement. By adjusting the connecting rod 50, the position of the operating section 30 can be flexibly arranged, which is user-friendly and convenient for spatial arrangement. Optionally, the connecting rod 50 can also be connected to the support section 23, and the operating section 30 is connected to the support section 23 by transmission. The movement of the support section 23 can drive the dust scraping section 20 to movement.In particular, the connecting rod 50 can comprise a first rod section and a second rod section, wherein one end of the first rod section is connected to the guide rod 21 and extends in the same direction as the guide rod 21, the other end of the first rod section is connected to one end of the second rod section, and the other end of the second rod section is connected to the operating section 30, wherein the first rod section and the second rod section have an angle between the rods at the connection or an angle between the lines of extension in their directions of extension, thereby allowing the setting position of the operating section 30 to be arranged flexibly.

[0109] In combination with Fig. 4 and Fig. 5. In some embodiments of the present application, the dust scraper further comprises: a guide rod 21 and a support section 23. The support section 23 is connected to the dust scraper element 22 via the guide rod 21 and can axially support the dust scraper element 22 to prevent shaking of the dust scraper element 22 during movement, thereby improving the structural and operational stability of the dust scraper element 22. In this way, even larger dirt adhering to the outside of the first filter 12 can be scraped off by the dust scraper element 22, which is advantageous for improving the cleaning effect and durability.

[0110] Furthermore, the guide rod 21 extends along the axial direction of the first filter 12, and one end of the guide rod 21 is connected to the dust scraper section 20. The support section 23 is connected to the other end of the guide rod 21 and is movably mounted on the main body 10, with the support section 23 being connected to the operating section 30 by transmission. The guide rod 21 extends along the axial direction, can guide the dust scraper element 22 for movement along the axial direction, and can also act as a support roller between the support section 23 and the dust scraper element 22, which is conducive to force distribution.

[0111] In combination with Fig. 3. According to some embodiments of the present application, the main body 10 further comprises a motor hood 16, a space for receiving the motor 40 is formed in the motor hood 16, the motor hood 16 and the first filter 12 are arranged axially, and the support section 23 is enclosed on the outside of the motor hood 16. In particular, the support section 23 can be arranged between the motor hood 16 and the outer shell of the cleaning device 100, which is conducive to receiving the support section 23, and the support section 23 can move axially along the motor hood 16, and when the support section 23 moves, the dust scraper element 22 can also move axially outside the first filter 12.

[0112] Combined with Fig. 3 In some embodiments of the present application, the main body 10 further comprises a guide section 60, which is arranged between the support section 23 and the dust scraper section 20. The guide section 60 is provided with a guide hole for the passage of the guide rod 21 and guides the guide rod 21 for axial movement, so that the dust scraper can extend axially along the main body 10, which can save space and contribute to improving the compactness of the device. In addition, the guide section 60 can limit the guide rod 21 in the radial direction to prevent the dust scraper from shaking during use.

[0113] Combined with Fig. 3 In some embodiments of the present application, the dust scraper further comprises a spring 24 which is enclosed on the guide rod 21. The two ends of the spring 24 bear against the guide section 60 and the support section 23, respectively, and the spring 24 is designed to provide a force to drive the dust scraper section 20 to retract, thus providing a restoring force for the dust scraper element 22, which automatically resets the dust scraper element 22, making it more convenient for the user. In use, the operating section 30 can drive the dust scraper to move towards the vicinity of the cup cover 112 in order to scrape the dust through the outside of the first filter 12.At this point, the support section 23 also moves towards the vicinity of the cup cover 112 or the guide section 60, and the spring 24 rests between the support section 23 and the guide section 60 and is compressed. When the driving force disappears, the restoring force of the spring 24 can drive the support section 23 and the dust scraper element 22 back into their original position, thus simplifying operation.

[0114] Combined with Fig. 1 and Fig. 2 In some embodiments of the present application, the cleaning device 100 comprises an air inlet pipe 18. The air inlet pipe 18 and the dust cup 11 are arranged side by side. The dust scraper and the air inlet pipe 18 have the same directions of extension, and the dust scraper is located outside the air inlet pipe 18. In particular, the air inlet pipe 18 and the dust cup 11 are arranged side by side and extend in the same direction, which can be advantageous for the spatial arrangement and improve the compactness of the device structure. The dust scraper is located outside the air inlet pipe 18, and the dust cup 11, the first filter 12, the dust scraper, and the air inlet pipe have the same directions of extension. On the one hand, it is advantageous to reduce the size of the cleaning device 100 and to simplify the spatial arrangement.Alternatively, the air inlet pipe can be arranged on the outer circumferential wall of the dust cup 11 and extend along the axial direction of the dust cup 11. In this way, the airflow can flow spirally out of the air inlet pipe 18 after entering the dust cup 11, which is advantageous for improving the separation effect. The dust scraper can collect and compress the dust in the dust compression chamber 101, thereby improving the cleaning effect and facilitating the collection and cleaning of dust.

[0115] Combined with Fig. 2 In some embodiments of the present application, the cleaning device comprises a filter 13 (i.e., the second filter 13) arranged upstream of the motor, which is at least partially located in the dust cup 11, which can improve the filtering effect. The dust scraping section 20 moves along the axial direction of the filter 13 arranged upstream of the motor, which is advantageous for the spatial arrangement and facilitates assembly.

[0116] A cleaning device 100 according to a specific embodiment of the present application is described below with reference to the attached drawings.

[0117] In combination with Fig. 1 to Fig. 6. According to the embodiment of the present application, the cleaning device 100 comprises a main body 10, a dust cup 11 connected to the main body 10, a handle 71, a motor 40, a power supply assembly 73, an air inlet tube 18, a second filter 13, and a third filter 15. In the present application, the cleaning device 100 adopts a lateral air inlet, such that the inlet 108 is located on one side of the dust cup 11. The second filter 13 and the third filter 15 are located upstream and downstream of the motor 40, respectively, along the airflow path for filtering the airflow, and the third filter 15 may overlap with the motor 40 depending on the prevailing conditions in the room. The dust cup 11, the motor 40, and the third filter 15 are arranged sequentially along the longitudinal axis of the dust cup 11, and the second filter 13 is located inside the dust cup 11.The power supply assembly 73 supports the entire cleaning device 100. The handle 71 is located between the motor 40 and the power supply assembly 73. The axis of the handle 71 does not pass through the motor 40, and the motor 40 is positioned further back relative to the axis of the handle 71. The handheld vacuum cleaner (i.e., the cleaning device 100) has a distal end and a proximal end, which are arranged opposite each other. The inlet 108 is located at the distal end, and the third filter 15 is located at the proximal end.

[0118] Furthermore, the dust cup comprises 11 in combination with Fig. 2. A cup body 111 and a cup cover 112 for pouring dust, and a first filter 12 and a fourth filter 19 are provided in the cup body 111. The first filter 12 is a filter mesh cover and has several through-holes on its surface for filtering dust with larger particle sizes. The fourth filter 19 is a multi-cone cyclone, and the fourth filter 19 comprises several small cones that are arranged circumferentially in the dust cup 11 and are located downstream of the first filter 12.

[0119] Combined with Fig. The cleaning device 100 further comprises a dust scraper, which includes a dust scraper section 20. The dust scraper section 20 is configured to move towards the cup cover 112 in order to squeeze the dust. The dust scraper section 20 includes a squeezing element 25 extending towards and adjacent to the inner wall of the dust cup 11, extending towards the dust cup 11 perpendicular to the axis of the dust cup 11. In such an arrangement, the squeezing element 25 compresses the dust, and the volume of the already collected dust can be compressed, thereby freeing up more space for dust separation or collection. This prevents excessive dust accumulation without discharge and avoids settling due to excessive attraction or separation efficiency.And after crushing dust, the user does not need to frequently empty the dust in the dust cup 11, which can shorten the cleaning process time, reduce the customer's workload, and improve the user experience.

[0120] Combined with Fig. 7 In one embodiment, an extension end of the squeezing element 25 can rest against the inner wall of the dust cup 11 to scrape off the dust from the inner wall of the dust cup 11, and the edge of the squeezing element 25 resting against the inner wall of the dust cup 11 can be a soft rubber strip structure or a bristle structure. Alternatively, by cleaning the inner wall of the dust cup 11, the dust cup 11 can be kept clean, and dust can be prevented from remaining on the inner wall.

[0121] In one embodiment, the dust scraping section 20 further comprises a dust scraping element 22 arranged near the first filter 12. The dust scraping element 22 can extend along the axial direction of the first filter 12 or obliquely in a direction close to the first filter 12 to cooperate with the outer surface of the first filter 12 and enhance the dust scraping effect. As the dust scraping element 22 pushes and scrapes the dust toward the cup cover 112, the dust adhering to the surface of the first filter 12 can be cleaned simultaneously. The dust scraping element 22 can be located at a certain distance from the first filter 12, but close enough. In such an arrangement, the dust adhering to the surface of the first filter 12 can be cleaned to prevent it from adhering to the first filter 12 and affecting the airflow efficiency.

[0122] The dust scraper comprises an operating section 30 for controlling the movement of the dust scraper section 20, a connecting rod 50, and a support section 23 fixed in the main body 10. The dust scraper section 20 is located in the starting position at an end of the first filter 12 facing the motor 40.

[0123] Combined with Fig. In one embodiment, three guide rods 21 are arranged for connecting and transmitting the movement of the operating section 30 between the support section 23 and the dust scraper section 20. One end of the connecting rod 50 is connected to the operating section 30, and the other end of the connecting rod 50 is connected to at least one of the guide rods 21 to drive the movement of the dust scraper section 20 when the connecting rod 50 is moved.

[0124] Combined with Fig. In one embodiment, the support section 23 is arranged around the periphery of the engine hood 16 and can move along the engine hood 16 when the operating section 30 is pushed. Since the crushing element 25 is connected to the support section 23 via the guide rod 21, the dust scraper section 20 moves in the same direction as the support section 23 moves along the engine hood 16, scraping the dust off the periphery of the first filter 12 and collecting and compressing the dust in the dust compression chamber 101.

[0125] In one embodiment, a spring 24 is enclosed on the guide rod 21. When pushing and scraping dust, the movement of the support section 23 drives the spring 24 to compress. After the dust scraping is complete, the dust scraping section 20 automatically resets due to the restoring force of the spring 24.

[0126] Combined with Fig. In one embodiment, the operating section 30 is located below the dust cup 11. This position can make it more convenient for users to perform the pushing and pulling, thus making the pushing and pulling action smoother.

[0127] In particular, the user can compress the dust several times during the cleaning process to free up more dust collection space without having to empty the dust cup 11 several times.

[0128] In actual operation, the airflow path of the entire cleaning device is 100 in combination with Fig. 1 and Fig. 2 as follows: The airflow enters the air inlet pipe 18 from the inlet 108, dust and air enter the dust cup 11 from the side of the dust cup 11, and the dust falls into the first dust collection chamber after filtration through the first filter 12. The airflow, containing a small amount of dust, then enters the fourth filter 19 for filtration, and the filtered fine dust falls into the second dust collection chamber. The airflow then enters the second filter 13 for filtration and flows towards the motor 40, finally passing through the third filter 15 and being discharged from the outlet.

[0129] In particular, dust and air enter the device from the inlet 108 and travel tangentially along the air duct into the dust cup 11. Under the influence of centrifugal force, the dust and debris rotate along the wall of the dust cup 11 towards the first dust collection chamber of the dust cup 11. Some of the dust passes through the first filter 12 and enters the fourth filter 19. Similarly, under the influence of centrifugal force, the dust rotates along the inner wall of the fourth filter 19 towards the second dust collection chamber at the bottom, and at the dust-gas separation opening, the gas passes through the porous air passage into the second filter 13 and into the motor 40, and is then filtered through the third filter 15 and discharged.By setting up two cyclone filtrations and using a multi-cone cyclone mechanism through the fourth filter 19, the separation efficiency of dust and air can be significantly increased, the number of times to clean the filter can be reduced, and the service life of the filter can be extended.

[0130] Combined with Fig. 2 The second filter 13 is located inside the first filter 12. The vacuum cleaner is equipped with the second filter 13. The filter 13, located in front of the motor, is provided with a handle 131. The handle 131 is used to remove the filter 13 located in front of the motor along the longitudinal axis of the dust cup 11. The handle 131 is located near the cup cover 112. The filter 13 located in front of the motor can be removed in one direction away from the cup cover 112. The third filter 15 can be removed by pulling it backwards. This arrangement facilitates the cleaning of the second filter 13 and the third filter 15. The second filter 13 is arranged coaxially with the first filter 12, and the dust scraper section 20 moves along the longitudinal axis of the second filter 13. More precisely, the second filter 13 comprises a filter cotton and a filter holder.After being filtered through the filter cotton, the airflow passes through a multitude of through-holes on the filter holder into the interior and flows in the inner channel to the motor 40.

[0131] As mentioned above, the second filter 13 is located in the center of the dust cup 11 and is connected to the fan assembly at the top via a sealing ring to allow quick disassembly and cleaning of the second filter 13, as shown in Fig. Figure 2 shows that after dust and gas separation, the gas passes through the porous air passage into the filter 13 located in front of the motor and then enters the motor 40 and is discharged. A small amount of fine ash typically adheres to the outer wall of the second filter 13. When the filter 13 located in front of the motor needs cleaning, the handle 131 can be grasped by hand at the hole position on the bottom of the dust cup 11 and pulled outwards. After cleaning, it can be reassembled in the same way. In this way, the second filter 13 can be quickly cleaned or replaced without disassembling other components, thus significantly improving user convenience and satisfaction.

[0132] As in Fig. 8 to Fig. As shown in Figure 15, the cleaning device 100 according to the embodiment of the present application can be used for vacuuming dust to clean the environment. The cleaning device 100 can comprise a main body 10, a drive assembly, a rear cover 80, and a display assembly 90.

[0133] The main body 10 has an airflow channel 110, and at least part of the drive assembly is arranged in the airflow channel 110 to drive the airflow. The rear cover 80 releasably covers the outlet of the airflow channel 110. The display assembly 90 is mounted on the drive assembly and separate from the rear cover 80. The display assembly 90 is designed to display information to the outside of the rear cover 80. In other words, the display assembly 90 can be used to display operating information or other information about the cleaning device 100. This arrangement can improve the operational stability of the display assembly 90 and prevent damage to it.

[0134] In particular, the display assembly 90 is installed on the drive assembly, and the drive assembly is located in the airflow duct 110. When the rear cover 80 is connected to the main body 10, it can cover the outlet of the airflow duct 110, thus encapsulating the drive assembly and the display assembly 90 on the main body 10. The rear cover 80 protects the structural components in the cleaning device 100, ensuring a stable connection between the drive assembly and the main body 10. Simultaneously, the display assembly 90 can project information outwards through the rear cover 80, and the rear cover 80 facilitates the display assembly 90's external projection. For example, at least part of the rear cover 80 can be designed with an opening 81, allowing the display assembly 90 to project information outwards through this opening 81.For example, at least part of the rear cover 80 can be designed as a transparent structure, and the display assembly 90 can show information through this transparent structure to the outside, thus improving user comfort. When the third filter 15 needs cleaning, the rear cover 80 can be removed from the main body 10. At this point, the display assembly 90, which is installed on the drive assembly, can be separated from the rear cover 80 to prevent it from falling and being damaged during removal. Furthermore, the display assembly 90, which is installed on the drive assembly, allows the circuits between the display assembly 90 and the drive assembly to be arranged and concealed, thereby ensuring the operational stability of the display assembly 90.

[0135] Furthermore, at least part of the drive assembly is arranged in the airflow channel 110, so that the cleaning device 100 has a more compact design and a smaller volume.

[0136] Therefore, according to the cleaning device 100 of the embodiment of the present application, the operational stability of the display assembly 90 can be improved and damage to the display assembly 90 can be avoided.

[0137] As in Fig. As shown in Figure 2, in some embodiments of the present application, the rear cover 80 can be configured such that it is independently detachable from the main body 10 relative to the display assembly 90; that is, the rear cover 80 can be detached independently from the main body 10, and the display assembly 90 does not need to be detached from the main body 10 when the rear cover 80 is detached from the main body 10. This arrangement can improve the operational stability of the display assembly 90, prevent damage to the display assembly 90, and facilitate the cleaning of the third filter 15.

[0138] In particular, after the cleaning device 100 has been used for a period of time, dust and other debris carried by the airflow will accumulate on the third filter 15. The user can remove the rear cover 80 from the main body 10 separately from the display assembly 90 to repair and maintain the interior of the cleaning device 100. At the same time, the display assembly 90 can remain securely mounted on the drive assembly to prevent it from falling and being damaged when the rear cover is removed. The electrical connection between the display assembly 90 and the main body 10 can also be maintained to ensure the normal operation of the display assembly 90.

[0139] In some embodiments of the present application, the drive assembly can comprise a motor 40, and the display assembly 90 can be installed on the air outlet side of the motor 40. It is understood that in the cleaning device 100, the motor 40 can be installed in the airflow duct 110, the air inlet side of the motor 40 can correspond to the inlet 108 of the airflow duct 110, the air outlet side of the motor 40 can correspond to the outlet 109 of the airflow duct 110, and the rear cover 80 can cover the outlet 109 of the airflow duct 110. Therefore, the display assembly 90 can be mounted on the air outlet side of the motor 40 so that the display assembly 90 can display information to the outside of the rear cover 80, thus making it convenient for users to obtain the operating information of the device.

[0140] Furthermore, the display assembly 90 can be installed at the end of the motor 40 near the outlet 109. In other words, the display assembly 90 can be located close to the outlet 109 of the airflow duct 110, so that the display assembly 90 can display information to the outside of the rear cover 80.

[0141] Alternatively, a mounting bracket 151 can be provided on the air outlet side of the motor 40, and the display assembly 90 can be mounted on the bracket 151. This arrangement prevents the display assembly 90 from blocking the air outlet side of the motor 40, thus allowing the motor 40 to easily drive the airflow through the airflow duct 110, while the display assembly 90 shows information to the outside of the rear cover 80.

[0142] In some embodiments of the present application, the drive assembly may further comprise a third filter 15.

[0143] The third filter 15 can be arranged on the air outlet side of the motor 40 and be located at the outlet 109 of the airflow duct 110, and the display assembly 90 can be mounted on the third filter 15 to realize the dust removal function of the cleaning device 100.

[0144] In particular, during operation of the cleaning device 100, the motor 40 can drive the airflow sequentially through the inlet 108 of the airflow duct 110, the airflow duct 110 and the outlet 109 of the airflow duct 110, and the airflow is filtered by the third filter 15 at the outlet 109, so that dust and other debris carried in the airflow can be filtered out by the third filter 15, thereby realizing the cleaning function of the cleaning device 100.

[0145] In some embodiments of the present application, at least a portion of the third filter 15 can extend from the outlet 109, and the rear cover 80 is enclosed on the outside of the third filter 15. It is understood that the display assembly 90 is installed on the outside of the third filter 15 and can be located on the air outlet side of the motor 40. In other words, the display assembly 90 can face the outlet 109 of the airflow duct 110. In this case, at least a portion of the third filter 15 can extend from the outlet 109, allowing the display assembly 90 to better project information outwards from the rear cover 80, thereby improving user comfort.

[0146] As in Fig. 8 to Fig. As shown in Figure 12, in some embodiments of the present application, the main body 10 can extend in a forward-backward direction, and the outlet 109 of the airflow channel 110 can be arranged at the rear end of the main body 10, and the display assembly 90 is arranged on the third filter 15 and displays information to the rear of the main body 10. This arrangement can make it easier for the user to obtain the operating information of the cleaning device 100, thereby improving user comfort.

[0147] The inlet 108 of the airflow channel 110 can be located at the front end of the main body 10. In other words, the airflow enters the inlet 108 of the airflow channel 110 from the front end of the main body 10 and, after passing through the airflow channel 110, is discharged from the outlet 109 at the rear end of the main body 10; or the main body 10 has a side wall extending in a forward-backward direction, and the inlet 108 of the airflow channel 110 can be located on the side wall of the main body 10. After entering the airflow channel 110, the airflow can flow along the tangential flow direction of the side wall of the main body 10 to filter a portion of the dust for the first time through the cyclone separation, then it can be discharged from the outlet 109 and filtered a second time through the third filter 15 to achieve dust removal by the cleaning device 100.

[0148] For example, in the forward-backward direction, the inlet 108 of the airflow channel 110 is located at the front end of the main body 10 and the outlet 109 of the airflow channel 110 is located at the rear end of the main body 10. It is understood that when the user operates the cleaning device 100, the front end of the main body 10, i.e., the inlet 108 of the airflow channel 110, can be aligned with the area to be cleaned, and the airflow driving action of the motor 40 can be used to complete the cleaning of the area by the cleaning device 100.Furthermore, the outlet 109 of the airflow duct 110 can be located at the rear end of the main body 10, and the display assembly 90 can be located on the third filter 15 such that the display assembly 90 can face the user, so that when using the cleaning device 100 the user can obtain the operating parameters of the cleaning device 100 via the display assembly 90 and also control the operation of the cleaning device 100 via the display assembly 90, thereby improving the user's ease of use.

[0149] As in Fig. As shown in Figure 14, in some embodiments of the present application, a display area may be provided on the rear cover 80, wherein the display area has an opening 81, a transparent area, or a semi-transparent area. Furthermore, when the rear cover 80 is installed on the main body 10, the display area may be arranged opposite the display assembly 90 to facilitate the display of information by the display assembly 90, thereby improving user comfort.

[0150] In particular, the third filter 15 can be located on the rear of the main body 10. When the rear cover 80 is installed on the main body 10, it can be positioned on the outside of the third filter 15 to encapsulate and protect it. Furthermore, a display area is provided on the rear cover 80. When the rear cover 80 is installed on the main body 10, the display area of ​​the display assembly 90 can be located opposite the third filter 15, allowing the display assembly 90 to project information to the rear of the main body 10 through the opening 81. This enables the user to obtain the operating parameters of the cleaning device 100 when using the cleaning device 100.

[0151] As in Fig. 9 to Fig. As shown in Figure 12, in some embodiments of the present application, the display assembly 90 can be arranged on the inside of the display area; at least a part of it can be embedded in the display area or extend from the display area. It is understood that the display assembly 90 is installed on the third filter 15. If the rear cover 80 is installed at the rear end of the main body 10, the display assembly 90 can be arranged on the inside of the display area, and the display area can be a transparent or semi-transparent area, so that the user can obtain the information from the display assembly 90 via the display area; or at least a part of the display assembly 90 can be embedded in the opening 81 of the display area to position the display assembly 90 through the opening 81. And the part of the display assembly 90 embedded in the opening 81 can display information, i.e.,The opening 81 allows the display assembly 90 to show information to the outside, thus improving user comfort. The rear cover 80 can also be used indirectly to position the third filter 15. Alternatively, at least part of the display assembly 90 can extend beyond the display area to show information to the rear of the cleaning device 100, making it easier for the user to obtain operating parameters of the cleaning device 100 and thus improving user comfort.

[0152] In other embodiments of the present application, the display surface of the display assembly 90 can be flush with the rear side surface of the rear cover 80. This arrangement can make the rear structure of the cleaning device 100 flat, thereby facilitating cleaning for the user.

[0153] In some other embodiments of the present application, at least part of the display assembly 90 is embedded in the opening 81, so that the display assembly 90 can be positioned and it can be ensured that the display assembly 90 can display information stably. At the same time, the display surface of the display assembly 90 is flush with the rear side surface of the rear cover 80, so that the rear side structure of the cleaning device 100 is flat, which is convenient for the user to clean.

[0154] As in Fig. 8 to Fig. As shown in Figure 12, in some embodiments of the present application, the third filter 15 can be installed at the end of the main body 10. In other words, in combination with the embodiments mentioned above, the third filter 15 can be installed at the rear end of the main body 10 to filter the airflow passing through the outlet 109 of the airflow channel 110 in order to achieve the dust removal function of the cleaning device 100.

[0155] Furthermore, at least part of the third filter 15 can be embedded in the main body 10. This arrangement can increase the contact area between the third filter 15 and the main body 10, thereby increasing the bond strength between the third filter 15 and the main body 10 to ensure that the third filter 15 can function normally.

[0156] Furthermore, the rear cover 80 can be connected to the main body 10 and position the third filter 15. In particular, the rear cover 80 has a circumferential wall extending in a forward-backward direction and has a first end and a second end that are arranged opposite each other. The first end of the rear cover 80 is open, and the rear cover 80 can be mounted to the main body 10 through its first end and positioned on the outside of the third filter 15 to allow for the mounting of the cleaning device housing 100, in order to protect the third filter 15 and the display assembly 90.Furthermore, a closed surface is provided at the second end of the rear cover 80, and an opening 81 may be provided in this closed surface. This allows the display assembly 90 to be positioned opposite the opening 81 when the rear cover 80 is installed on the main body 10. The display assembly 90 can then display information to the rear of the main body 10, enabling the user to obtain the operating parameters of the cleaning device 100. A mounting section may also be provided on the closed surface. This mounting section may project forward. When the rear cover 80 is installed on the main body 10, the mounting section can rest against the rear of the third filter 15 to position the third filter 15 and ensure its proper functioning.

[0157] As in Fig. As shown in Figure 13, in some embodiments of the present application, the third filter 15 can be mounted on the outside of the motor 40, and the third filter 15 partially overlaps the motor 40 in the projection in a predetermined direction, the predetermined direction being perpendicular to the axis of the motor 40. It is understood that at least part of the motor 40 can be mounted on the inside of the third filter 15 in order to reduce the volume of the mounting part of the motor 40 and the third filter 15, thereby improving integration and miniaturizing the cleaning device 100.

[0158] In some embodiments of the present application, the third filter 15 is detachably mounted on the main body 10. It is understood that the third filter 15 and the main body 10 are segmented structures. Such an arrangement can facilitate the processing and manufacture of the cleaning device 100 and reduce the complexity of the manufacturing process.

[0159] Naturally, the third filter 15 and the main body 10 can be an integrated structure, thereby increasing the structural strength of the cleaning device 100.

[0160] Furthermore, in combination with the above-mentioned embodiments, the rear cover 80 and the third filter 15 are detachably mounted on the main body 10, i.e., by disassembling and assembling the third filter 15 and the main body 10, the rear cover 80 and the third filter 15 can be simultaneously disassembled and assembled on the main body 10.

[0161] As in Fig. 9 and Fig. As shown in Figure 15, the third filter 15 in some embodiments of the present application may comprise a holder 151 and a filter element 152.

[0162] The holder 151 has a hollow structure 1511, which is connected to the main body 10. The hollow structure 1511 communicates with the airflow channel 110, and the filter element 152 shields the hollow structure 1511. Therefore, the airflow in the airflow channel 110 can be filtered to enable the dust removal and display functions of the cleaning device 100.

[0163] In particular, the third filter 15 is installed on the outside of the motor 40. When the cleaning device 100 is operating, the motor 40 can drive the airflow in the airflow channel 110 to flow towards the cavity structure 1511. At this point, the filter element 152 can shield the cavity structure 1511 on the holder 151. As the airflow in the airflow channel 110 flows towards the cavity structure 1511, the filter element 152 can filter the airflow to remove the dust and other debris carried in the airflow, thus realizing the dust removal function of the cleaning device 100.

[0164] Furthermore, the holder 151 has a first end and a second end that are arranged opposite each other. The hollow structure 1511 is arranged between the first end and the second end of the holder 151, the first end of the holder 151 is connected to the main body 10, and the display assembly 90 is arranged at the second end of the holder 151 to implement the dust removal function of the cleaning device 100.

[0165] Specifically, the first and second ends are aligned along the forward-backward direction (where the forward-backward direction is the same as the direction of the axis), and the second end is positioned backward relative to the first end. At this point, the display assembly 90 can be positioned at the second end of the holder 151. In other words, the display assembly 90 is positioned on the rear side of the third filter 15 such that it can face backward to display the operating parameters of the cleaning device 100 to the user, thereby improving user comfort.

[0166] Furthermore, a recessed structure 1511 is provided between the first and second ends, extending perpendicular to the predetermined direction and communicating with the airflow channel 110, so that the airflow from the airflow channel 110 can be discharged in a predetermined direction. The display assembly 90 is installed at the second end and displays information along the axial direction of the motor 40 to the rear. Simultaneously, the airflow can be discharged in a predetermined direction through the recessed structure 1511, and the filter element 152 arranged on the recessed structure 1511 can filter the airflow. Therefore, when the information display is implemented by the display assembly 90, the holder 151 can guide, discharge, and filter the airflow.In comparison to the separate reservation of assembly space for the display assembly 90 and the filter element 152, the present application improves the space utilization rate of the cleaning device 100.

[0167] As in Fig. As shown in Figure 15, in some embodiments of the present application, the first end of the holder 151 can be provided with a positioning ring 1512 and the second end with an end cover 1513. The positioning ring 1512 and the end cover 1513 are connected by a connecting rib 1514 to form the recessed structure 1511 between the positioning ring 1512 and the end cover 1513. The display assembly 90 is installed on a side of the end cover 1513 facing away from the positioning ring 1512. In this way, the dust removal and display functions of the cleaning device 100 can be implemented.

[0168] In particular, the positioning ring 1512 can be mounted on the rear of the main body 10. When the airflow from the airflow channel 110 enters the holder 151, it can pass through the positioning ring 1512 into the interior of the holder 151. Guided by the end cover 1513, the airflow can flow into the cavity structure 1511 formed between the positioning ring 1512 and the end cover 1513 and be discharged through the cavity structure 1511 in a predetermined direction. During this process, the filter element 152 can cover the cavity structure 1511 to filter the airflow passing through it, thereby achieving the dust removal effect of the cleaning device 100.

[0169] Furthermore, the display assembly 90 can be mounted on a side of the end cover 1513 facing away from the positioning ring 1512, so that the display assembly 90 can display information backwards, thereby improving ease of use for the user.

[0170] Secondly, a ventilation opening 82 can be provided on the rear cover 80. When the rear cover 80 is installed on the main body 10, the ventilation opening 82 can be opposite the cavity structure 1511, so that the airflow can be discharged in a predetermined direction through the cavity structure 1511 and subsequently the ventilation opening 82 into the external environment.

[0171] As in Fig.As shown in Figure 15, in some embodiments of the present application an annular rib 15131 can be provided on the end cover 1513, and a groove 15132 is formed in the annular rib 15131 for mounting the display assembly 90. Therefore, the mounting strength of the display assembly 90 can be improved by the annular rib 15131.

[0172] In particular, an annular rib 15131 is provided on the end cover 1513, extending along the axial direction of the motor 40 to project relative to the surface of the end cover 1513, thereby forming the groove 15132. The display assembly 90 can then be installed in the groove 15132 to facilitate its mounting. Furthermore, when the rear cover 80 is mounted on the main body 10, a portion of the rear cover 80's structure can abut the end cover 1513 to position the holder 151 and improve its mounting strength.

[0173] Furthermore, an opening 81 is provided on the rear cover 80, and the annular rib 15131 is embedded in the opening 81, so that the display assembly 90 installed in the groove 15132 can display information to the rear of the cleaning device 100 via the opening 81, thereby improving the convenience of the operating information for the users.

[0174] In some specific examples of the present application, the cleaning device 100 has a holder 151, the display screen (i.e., the display assembly 90) is mounted at the end of the holder 151 and faces rearward, and the rear cover 80 is provided with a through-hole or a transparent structure in a position corresponding to the display screen, so that the content of the display screen can be observed through the rear cover. In this embodiment, the rear cover is provided with a through-hole, and of course, in other embodiments, a transparent structure can be used to view the content displayed on the screen.

[0175] In some specific examples of the present application, the filter located downstream of the motor (i.e., the third filter 15) can comprise two parts. Since the end of the holder 151 is used for mounting the display screen, space remains on both sides of the holder. Therefore, the design of the holder 151 and the two-part structural construction of the filter located downstream of the motor allow the structure of the holder 151 and its interior to be fully utilized, and the structural arrangement to be sensibly configured, resulting in a more compact overall structure of the vacuum cleaner and thus promoting miniaturization of the machine.

[0176] In some specific examples of the present application, a filter assembly may be provided in the main body 10, comprising a first filter 12, a fourth filter 19 and a filter arranged upstream of the motor (i.e. a second filter 13), wherein a first dust collection chamber is provided between the first filter 12 and the fourth filter 19 and a second dust collection chamber is provided between the fourth filter 19 and the filter arranged upstream of the motor, and the first dust collection chamber and the second dust collection chamber can be used to collect the dust and other debris filtered from the airflow.

[0177] The airflow path of the cleaning device 100 can be as follows: The airflow enters the air inlet pipe from the inlet 108. Dust and air enter the main body 10 from the side of the main body 10, and the dust, after being filtered through the first filter 12, falls into the first dust collection chamber. The airflow, containing a small amount of dust, then enters the fourth filter 19 for further filtration, and the filtered fine dust falls into the second dust collection chamber. The airflow continues to enter the filter located upstream of the motor for further filtration and flows towards the motor, finally passing through the filter located downstream of the motor (i.e., the third filter 15) and is discharged from the outlet 109.

[0178] Specifically, dust and air exit through an intake opening 108 and enter the main body 10 through the intake opening 108. Under the influence of a centrifugal force, the dust and debris rotate along the wall of the main body 10 towards the first dust collection chamber of the main body 10. A crimp is formed under the filter mesh cover (i.e., the first filter 12) at a certain angle to the horizontal direction (the horizontal direction being the same as the axial direction). The crimp under the filter mesh cover prevents the dust, which enters the bottom due to the centrifugal force, from re-entering the multi-cone cyclone (i.e., the fourth filter 19), thus effectively reducing the total amount of dust entering the multi-cone cyclone (i.e., the fourth filter 19). Some of the dust passes through the filter mesh cover (i.e., the first filter 12) and enters the multi-cone cyclone (i.e., the fourth filter 19).Similarly, under the influence of centrifugal force, the dust rotates along the wall of the multi-cone cyclone (i.e., the fourth filter 19) towards the second dust collection chamber at the bottom. At the dust-gas separation orifice, the gas passes through the porous air passage into the filter located upstream of the motor and then into the motor, where it is subsequently filtered and discharged by the filter located downstream of the motor. In this case, by implementing two cyclone filtration stages and using a multi-cone cyclone mechanism for secondary filtration, the separation efficiency of dust and air can be significantly increased, the number of times the filter needs to be cleaned reduced, and the filter's service life extended.

[0179] By installing the filter located in front of the motor and the filter located after the motor, filtration is carried out at both the motor air inlet and motor air outlet ends to improve separation efficiency.

[0180] The screen is positioned on the holder 151 and the filter, located after the motor, is installed using the structure of the holder 151, so that the space is used sensibly, the structure of the entire machine is more compact and a fall and damage to the screen is prevented.

[0181] The handheld vacuum cleaner (i.e., the cleaning device 100) comprises a main body 10, a dust cup connected to the main body 10, a handle, a motor, a battery, an air inlet, a filter arranged upstream of the motor, and a filter arranged downstream of the motor (i.e., a third filter 15). The handheld vacuum cleaner of the present application may have a side air inlet, such that the air inlet is located on the side of the dust cup. The filter arranged upstream of the motor and the filter arranged downstream of the motor are located, respectively, at the front and rear of the motor on the airflow path for filtering the airflow, and the filter arranged upstream of the motor is located in the dust cup and at least partially in the primary filter.

[0182] The filter located after the motor may overlap with the motor depending on the ambient conditions. The dust cup, the motor, and the filter located after the motor are arranged sequentially along the longitudinal axis of the dust cup. The battery powers the entire handheld vacuum cleaner, and the handle is located between the motor and the battery. The handle's axis does not pass through the motor, and the motor is positioned further back relative to the handle's axis. The handheld vacuum cleaner has a distal end and a proximal end, which are positioned opposite each other. The air inlet is located at the distal end, and the filter located after the motor is located at the proximal end.

[0183] The dust cup comprises a cup body, a cup cover for pouring dust, a first filter within the cup body, and a fourth filter 19, wherein the first filter 12 can be a filter mesh covering with multiple through-holes on its surface for filtering dust with larger particle sizes. The fourth filter 19 is a multi-cone cyclone. The fourth filter 19 comprises several small cones arranged circumferentially within the dust cup and positioned downstream of the first filter 12. The dust cup is further provided with a locking button for securing the cup cover.

[0184] The filter located upstream of the motor is situated within the first filter 12. The vacuum cleaner is equipped with a handle for removing the filter located upstream of the motor along the longitudinal axis of the dust cup. The handle of the filter located upstream of the motor is near the cup cover, and the filter is removed by pulling it away from the cup cover. The filter located downstream of the motor can be removed from the rear, allowing for easy cleaning of both the upstream and downstream filters. The filter located upstream of the motor is arranged coaxially with the first filter 12. The filter located upstream of the motor comprises a filter holder 151 and filter cotton arranged on the filter holder 151.After the airflow is filtered through the filter cotton, the airflow passes through several through holes on the filter holder 151 into the interior and flows from the inner channel towards the motor.

[0185] As mentioned previously, to allow for quick removal and cleaning of the filter located in front of the motor, it is designed with a quick-release mechanism (without having to remove the entire dust cup). The filter is located in the center of the dust cup and communicates with the fan assembly via a sealing ring on its top. After dust and gas separation, the exhaust gas enters the filter through the porous air passage, enters the motor, and is then expelled. A small amount of fine ash typically adheres to the outer wall of the filter. When the filter needs cleaning, the handle can be grasped by hand at the opening on the bottom of the dust cup and pulled outwards. Reassembly can be carried out in the same way after cleaning.In this way, the filter located in front of the engine can be quickly cleaned or replaced without having to dismantle other components, thus significantly improving user comfort and satisfaction.
