Description

Technical Field

[0001] This application relates to the field of vacuum cleaner technology, and more particularly to a cleaning device. Background Technology

[0002] As residents' living standards improve, cleaning devices such as vacuum cleaners are increasingly widely used in homes and industries. In particular, vacuum cleaners equipped with self-cleaning functions have an internal module that can automatically clean the filter. This allows the filter to be cleaned using high-pressure or negative-pressure airflow generated by the motor without the need for manual removal, thus maintaining continuous and stable suction power and cleaning efficiency.

[0003] However, some existing automatic self-cleaning vacuum cleaners typically require multiple drive units or complex drive mechanisms to control valves or baffles in different parts of the air duct during vacuuming and self-cleaning modes, thus switching the air duct to achieve different functions. However, multiple drive units or complex drive mechanisms not only increase manufacturing costs but also make assembly and maintenance more complicated, potentially leading to higher failure rates.

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0048] It should be understood that, unless otherwise expressly specified and limited, in the description of this application, the terms "inner," "outer," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0049] See Figure 1 and Figure 2This embodiment provides a cleaning device 100, including a head assembly and a dust bin. The head assembly is connected above the dust bin and is used to provide a power structure, a filter section, and a control structure, etc. The dust bin is mainly used to collect dust, and the head assembly is detachably installed on the dust bin.

[0050] See Figures 1 to 13 The cleaning device 100 includes a housing 1, a motor 2, and a filter 3. The housing 1 includes the outer shell of the head assembly and a dust bin. The housing 1 has an air inlet 11, an air outlet 12, and a replenishment air inlet 13.

[0051] The motor 2 is housed within the housing 1. The motor 2 has an air inlet 21 and an air outlet 22, which are used to generate negative pressure to form an airflow channel. The airflow channel referred to here refers to the channel formed by the entire path of airflow within the housing 1 under the action of the motor 2, including the channel inside the motor 2 and the channel outside the motor 2.

[0052] The filter 3 is disposed inside the housing 1 and located in the airflow channel, and is used to filter dirt in the airflow.

[0053] In this embodiment, the air inlet 11 is located in the dust bin, and the air outlet 12 is located in the outer shell of the head assembly.

[0054] The cleaning device 100 also includes a self-cleaning valve 4, an air supply valve 5, and a baffle 6.

[0055] The self-cleaning valve 4 is used to open the exhaust passage and close the self-cleaning passage, or close the exhaust passage and open the self-cleaning passage. The exhaust passage is the passage from the motor outlet 22 to the outlet 12, and the self-cleaning passage is the passage from the motor outlet 22 to the filter 3.

[0056] The air supply valve 5 is used to open or close the air supply channel, which is the channel from the air supply port 13 to the motor air inlet 21.

[0057] The baffle 6 is used to open or close the filter channel, which is the channel from the filter 3 to the motor air inlet 21.

[0058] The cleaning device 100 has a first state and a second state, and can switch between the first state and the second state.

[0059] In the first state, the cleaning device 100 performs a vacuuming operation; in the second state, the cleaning device 100 performs a self-cleaning operation on the filter 3.

[0060] See Figure 8 , Figure 10 and Figure 12 In the first state, baffle 6 opens the filter channel, self-cleaning valve 4 opens the exhaust channel and closes the self-cleaning channel, and air supply valve 5 closes the air supply channel.

[0061] Thus, under the action of motor 2, the airflow carrying dust enters the dust bin through the air inlet 11, the dust falls into the dust bin, the airflow passes through filter 3, then enters the motor air inlet 21 through the filter channel, and then exits the cleaning device 100 through the exhaust channel from the motor air outlet 22, thereby achieving the dust suction effect.

[0062] See Figure 9 , Figure 11 and Figure 13 In the second state, baffle 6 closes the filter channel, self-cleaning valve 4 opens the self-cleaning channel and closes the exhaust channel, and air supply valve 5 opens the air supply channel.

[0063] Thus, under the action of motor 2, outside air enters motor air inlet 21 from air inlet 13 through air inlet channel, and then flows to filter 33 from motor air outlet 22 through self-cleaning channel. After self-cleaning filter 3, it is discharged from cleaning device 100 through air inlet 11 on dust bin.

[0064] See Figures 2 to 4 as well as Figure 6 The cleaning device 100 also includes a drive mechanism 7.

[0065] See Figure 3 The drive mechanism 7 includes a moving part 72 driven by a single power source. The baffle 6, the self-cleaning valve 4, and the air supply valve 5 are directly or indirectly connected to the moving part 72 to be driven to perform opening and closing actions.

[0066] In the first state, the baffle 6 is driven to open the filter channel, the self-cleaning valve 4 is driven to open the exhaust channel and close the self-cleaning channel, and the air replenishment valve 5 is driven to close the air replenishment channel.

[0067] In the second state, the baffle 6 is driven to close the filter channel, the self-cleaning valve 4 is driven to close the exhaust channel and open the self-cleaning channel, and the air replenishment valve 5 is driven to open the air replenishment channel.

[0068] The cleaning device 100 of this application, driven by a single power source, simultaneously drives the baffle 6, the self-cleaning valve 4, and the air supply valve 5 to coordinate and control the opening and closing of the baffle 6, the self-cleaning valve 4, and the air supply valve 5. This enables the opening and closing control and switching of the filter channel, the exhaust channel, the self-cleaning channel, and the air supply channel, thereby allowing the cleaning device 100 to switch between a first state and a second state for vacuuming or self-cleaning as needed. Furthermore, it simplifies the control and transmission structure, improves the reliability of control, significantly reduces the manufacturing cost of the cleaning device 100, and facilitates assembly and maintenance. This makes the cleaning process of the filter 3 more efficient and more automated, greatly reducing the failure rate.

[0069] In this embodiment, the power source is an electromagnetic drive 71, the moving part 72 is a guide rod 721, the electromagnetic drive 71 is connected to the guide rod 721 and drives the guide rod 721 to move, and the self-cleaning valve 4 and the air supply valve 5 are respectively connected to the guide rod 721 and move synchronously with the guide rod 721.

[0070] Electromagnetic drive has the advantages of reliable operation and rapid switching. By using electromagnetic drive component 71 as a power source, the driven components of the cleaning device 100 can react quickly and promptly when switching between the first and second states, thereby improving self-cleaning efficiency and dust collection efficiency in practical applications.

[0071] The electromagnetic drive unit 71 drives the guide rod 721 to move, and the self-cleaning valve 4 and the air replenishment valve 5 are respectively connected to the guide rod 721 and move synchronously with it. This linkage design allows the electromagnetic drive unit 71 to drive the guide rod 721 to move when switching to the first state and activating the dust collection mode. This movement causes the baffle 6 to move to open the filter channel, the self-cleaning valve 4 to move to open the exhaust channel and close the self-cleaning channel, and the air replenishment valve 5 to move to close the air replenishment channel. When switching to the second state and activating the self-cleaning mode, the electromagnetic drive unit 71 drives the guide rod 721 to move, causing the baffle 6 to move to close the filter channel, the self-cleaning valve 4 to move to close the exhaust channel and open the self-cleaning channel, and the air replenishment valve 5 to move to open the air replenishment channel. This allows for rapid switching between the two states and the opening and closing of the airflow path, while reducing manufacturing and assembly costs and improving the efficiency and reliability of the baffle 6 and valve control.

[0072] The housing 1 has a filter chamber for accommodating the filter 3, and the filter channel has a filter outlet 31. The filter 3 is connected to the motor 2 through the filter outlet 31. Specifically, in this embodiment, the filter outlet 31 is located on the wall of the filter chamber.

[0073] See Figure 5 The filter outlet 31 and the baffle 6 are located on the first side of the filter chamber, and the air inlet 13 and the air inlet valve 5 are located on the second side of the filter chamber. The first side and the second side are adjacent to each other.

[0074] In this embodiment, see Figure 7 , Figure 11 and Figure 12 The filter 3 and the motor 2 are arranged side by side with a gap, and the baffle 6 is located between the filter 3 and the motor 2. This is conducive to the airflow passing through the filter 3 being sent into the motor 2 as soon as possible in the first state.

[0075] For ease of description, the arrangement direction of filter 3 and motor 2 is defined as the first direction, which is perpendicular to the axis of motor 2. The direction that is perpendicular to both the first direction and the axis of motor 2 is defined as the second direction.

[0076] In this embodiment, the first side is the side of the filter chamber along the first direction and facing the motor 2, and the second side is one of the two sides of the filter chamber along the second direction.

[0077] See Figure 3 , Figure 6 ,as well as Figures 13 to 15 The drive mechanism 7 also includes a linkage assembly 73, and the baffle 6 is connected to the air supply valve 5 through the linkage assembly 73.

[0078] Thus, by positioning the filter outlet 31 and the air inlet 13 on adjacent sides of the filter chamber, the connection between the baffle 6 and the air inlet valve 5 is facilitated. This allows the guide rod 721 to drive the air inlet valve 5 and the baffle 6 to move synchronously, resulting in a compact structure and improved space utilization of the cleaning device 100. Connecting the baffle 6 and the air inlet valve 5 via the linkage assembly 73 not only simplifies the structure and ensures reliability but also reduces costs. When the electromagnetic drive 71 drives the guide rod 721, the baffle 6 and the air inlet valve 5 move in tandem via the linkage assembly 73, achieving a smooth switch between the dust collection mode and the self-cleaning mode, improving system reliability and ease of assembly.

[0079] The linkage assembly 73 includes multiple interconnected links 731 to transmit force. The number of links 731 and the length of each link 731 can be set according to the distance and position between the baffle 6 and the air supply valve 5. Figure 3 As shown, the number of links 731 can be four, such as... Figure 12 , 13 As shown, the number of links 731 can also be two.

[0080] The drive mechanism 7 also includes a transmission component 74, which is sleeved on the guide rod 721. The air replenishment valve 5 is connected to the guide rod 721 via the transmission component 74, which is located on the side of the self-cleaning valve 4 facing the drive component. By setting the transmission component 74 between the guide rod 721 and the air replenishment valve 5, motion interference between the air replenishment valve 5, the electromagnetic drive component 71, and the self-cleaning valve 4 during the opening and closing process is avoided, the internal space layout is optimized, and the overall reliability of the cleaning device 100 is improved.

[0081] See Figure 14The transmission component 74 includes a first plate 741 and a second plate 742 that are perpendicularly connected to each other. The first plate 741 is sleeved on the guide rod 721, and the second plate 742 is connected to the air supply valve 5. The air supply valve 5 is located on the side of the first plate 741 facing the drive component, and the second plate 742 is located between the drive component and the air supply valve 5. This structural design makes the arrangement of the air supply valve 5 and the transmission component 74 more compact. The perpendicular connection of the two plates realizes the adaptation of movement in different directions and the smooth force transmission, which enhances the assembly convenience and overall reliability of the cleaning device 100.

[0082] See Figure 15 The air replenishment valve 5 includes a door plate 51, a first mating part 52, and a second mating part 53. The door plate 51 is used to open or close the air replenishment channel. The first mating part 52 mates with the second plate 742, and the second mating part 53 is connected to the connecting rod assembly 73. The second mating part 53 is located on the side of the first mating part 52 away from the driving member. Through the structural design of the air replenishment valve 5, the second mating part 53, which is connected to the connecting rod assembly 73, is located on the side of the first mating part 52 away from the driving member, thereby avoiding mechanical interference between the connecting rod assembly 73 and the electromagnetic driving member 71. Moreover, the first mating part 52 and the second mating part 53 are respectively connected to the transmission member 74 and the connecting rod assembly 73, realizing efficient force transmission and stable assembly, enhancing the reliability of the cleaning device 100 during air replenishment channel switching and the convenience of assembly and maintenance.

[0083] See Figure 16 The baffle 6 includes a rotating shaft 61 and a plate 62 pivotally connected to the rotating shaft 61. The rotating shaft 61 is located at one end of the plate 62, and a connecting rod assembly 73 is connected to the end of the plate 62 away from the rotating shaft 61. The drive mechanism 7 drives the plate 62 to rotate around the rotating shaft 61 to open or close the filter channel. By setting the rotating shaft 61, the plate 62 can rotate around the rotating shaft 61. When the electromagnetic drive 71 drives the guide rod 721 to move, the connecting rod assembly 73 transmits the transmission action to the plate 62, realizing the smooth opening and closing of the filter channel. This not only has a simple structure but also ensures reliable cooperation of the baffle 6 in a limited space, improving the working stability of the cleaning device 100.

[0084] See Figure 3 and Figure 12 The drive mechanism 7 also includes an elastic element 75.

[0085] See Figure 13 In the second state, the drive member drives the linkage assembly 73 to act on the baffle 6, so that the baffle 6 closes the filter channel and the elastic member 75 undergoes compression deformation.

[0086] See Figure 12In the first state, the driving member drives the linkage assembly 73 to act on the baffle 6 so that the baffle 6 opens the filter channel, and the elastic member 75 drives the baffle 6 to open the filter channel under the action of its own elastic restoring force.

[0087] By setting the elastic element 75, the elastic restoring force of the elastic element 75 can assist the baffle 6 to reset in the first state, reducing the load on the electromagnetic drive element 71, realizing the stable opening and closing of the filter channel, and improving the operating efficiency and reliability of the cleaning device 100.

[0088] In this embodiment, the elastic element 75 is a spring; in other embodiments, the elastic element 75 may also be a sheet, a torsion spring, or a shape memory structure, etc.

[0089] The air supply valve 5 and the elastic element 75 are both located on the side of the baffle 6 facing the filter 3. This arrangement allows the air supply valve 5 and the elastic element 75 to be more compactly placed on the side of the filter 3 when the baffle 6 is closed or the filter channel is open, avoiding interference with other components. It also makes the overall layout of the drive mechanism 7 more reasonable, reduces the complexity of pipeline routing and installation space, and improves the ease of assembly and maintenance of the cleaning device 100.

[0090] See Figure 16 The plate body 62 includes a main body section 621 and an action section 622 connected to each other. The main body section 621 is used to open or close the filter outlet 31. The rotating shaft 61 is located at the end of the main body section 621 away from the action section 622. The elastic member 75 abuts against the action section 622 and is located on the side of the action section 622 facing the filter 3. The elastic member 75 is located between the connecting rod assembly 73 and the rotating shaft 61.

[0091] Among them, the active segment 622 gradually moves away from the filter 3 from one end connected to the main body segment 621 to the other end.

[0092] The segmented structure of the baffle 6 provides sufficient space for the installation and movement of the elastic element 75, and ensures that the baffle 6 fits the filter outlet 31 more closely when closing the filter outlet 31, thus improving the sealing performance.

[0093] The linkage assembly 73 is connected to the end of the actuating section 622 away from the main body section 621 so that the linkage assembly 73 can drive the baffle 6 to move.

[0094] The filter 3 has two filter surfaces arranged opposite each other. In the first state, airflow enters the filter 3 from one filter surface and exits the filter 3 from the other filter surface. The filter surfaces are arranged along a direction perpendicular to the axis of the motor 2.

[0095] In summary, the cleaning device 100 provided in this application, through a single power source driving the moving part 72, simultaneously drives the baffle 6, the self-cleaning valve 4, and the air replenishment valve 5 to coordinate and control the opening and closing of the baffle 6, the self-cleaning valve 4, and the air replenishment valve 5, thereby realizing the opening and closing control and switching of the filter channel, the exhaust channel, the self-cleaning channel, and the air replenishment channel. This allows the cleaning device 100 to switch between a first state and a second state, so as to perform vacuuming or self-cleaning as needed. Moreover, it simplifies the control and transmission structure, improves the reliability of control, greatly reduces the manufacturing cost of the cleaning device 100, and facilitates assembly and maintenance, making the cleaning process of the filter 3 more efficient and more automated, and greatly reducing the failure rate.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
