[0046] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted in this application.

[0047] An embodiment of this application provides a cleaning mechanism disposed in a dust cup 10 of a cleaning device. A filtering component 4 is disposed in the dust cup 10.

[0048] As Figures 1 to 6 shown, the cleaning mechanism includes a bracket assembly 1, a cleaning assembly 2, and a cleaning rod assembly 3. The bracket assembly 1 is disposed in the dust cup 10 and sleeved on the filtering component 4. The bracket assembly 1 can move in the dust cup 10. The cleaning assembly 2 is disposed on the bracket assembly 1 and can move with the bracket assembly 1 to clean the inner wall of the dust cup 10 and the filtering component 4 during the movement. Specifically, the cleaning assembly 2 includes a first cleaning member 21, a second cleaning member 22, and a third cleaning member 23 (or at least one of them). The first cleaning member 21 cooperates with the inner wall of the dust cup 10 to remove the dirt attached to the inner wall of the dust cup 10. The second cleaning member 22 cooperates with a primary filter 41 of the filtering component 4 to remove the dirt attached to the primary filter 41. The third cleaning member 23 cooperates with a secondary filter 42 located in the primary filter 41 of the filtering component 4 to remove the dirt attached to the secondary filter 42. The cleaning rod assembly 3 is connected to the bracket assembly 1, and drives the bracket assembly 1 and the cleaning assembly 2 to move axially in the dust cup 10 along the axial direction of the dust cup 10 to clean the inner wall of the dust cup 10 and the filtering component 4.

[0049] The cleaning mechanism of the embodiment of this application can clean both the inner wall of the dust cup 10 and the filtering component 4 after the garbage is poured out, and clean off the attached dust or residual dirt (collectively referred to as dirt), avoiding the problem of manually taking out the filtering component 4 from the dust cup 10 for cleaning, making the cleaning easy and labor-saving, and enabling the cleaning device (such as a vacuum cleaner) applying this cleaning mechanism to always maintain the best dust suction performance; moreover, since there is no need to disassemble the dust cup 10 to take out the filtering component 4, it also avoids the problems of possible secondary dust emission and environmental secondary pollution.

[0050] In some embodiments, as Figures 1 to 3 as well as Figure 5 and Figure 6 shown, the cleaning rod assembly 3 includes a manual handle 33. The manual handle 33 is exposed outside the bottom of the dust cup 10. By pushing and pulling the manual handle 33, the bracket assembly 1 and the cleaning assembly 2 can be driven to move, realizing the cleaning of the inner wall of the dust cup 10 and the filtering component 4. The cleaning operation is convenient, the structure is simple, no power is required, and the cost is low.

[0051] In some embodiments, as Figure 2As shown, the bracket assembly 1 includes a first bracket body 11 and a second bracket body 12. The first bracket body 11 is cylindrical and sleeved outside the primary filter 41. An annular first cleaning member 21 is provided on the outer peripheral surface of the first bracket body 11, and an annular second cleaning member 22 is provided on the inner peripheral surface of the first bracket body 11. The second bracket body 12 is fixed to the cleaning rod assembly 3 and is annular. An annular third cleaning member 23 is provided on the inner peripheral surface of the second bracket body 12. The bracket assembly 1 has a reasonable structure, facilitating the arrangement of the three cleaning members and enabling the three cleaning members to respectively correspond to the inner wall of the dust cup 10 and the two filters.

[0052] It can be understood that the three cleaning members are preferably arranged in one circle respectively to achieve comprehensive cleaning. In addition, the outer wall shape of the first bracket body 11 is adapted to the inner wall shape of the dust cup 10, the inner wall shape of the first bracket body 11 is adapted to the outer wall shape of the primary filter 41, the inner wall shape of the second bracket body 12 is adapted to the outer wall shape of the secondary filter 42, and the three cleaning members respectively protrude from the peripheral surface of their respective bracket bodies, so that the three cleaning members can all be in contact with the components to be cleaned to achieve cleaning.

[0053] The specific structural forms and materials of the three cleaning members are not limited. For example, they can all be cleaning brushes. The first cleaning member 21 can be made of relatively hard nylon brushes to facilitate cleaning the dirt attached to the inner wall of the dust cup 10. The second cleaning member 22 and the third cleaning member 23 can be made of relatively soft fluff brushes to avoid damaging the filter assembly 4 during the cleaning process. The three cleaning members can be fixed to the first bracket body 11 and the second bracket body 12 respectively by means of, for example, bonding.

[0054] In some embodiments, as Figure 1 and Figure 2 shown, the cleaning rod assembly 3 further includes a rod body 31 and a connecting member 32 provided at the first end of the rod body 31. A manual handle 33 is provided at the second end of the rod body 31. The connecting member 32 is fixed to the outer peripheral wall of the first bracket body 11. The second bracket body 12 is fixed to the side of the connecting member 32 and extends into the annular cavity 111 of the first bracket body 11. The manual handle 33 is located outside the bottom of the dust cup 10. By pushing and pulling the manual handle 33, the bracket assembly 1 and the cleaning assembly 2 can be driven to move. Through the ingenious connection and cooperation between the cleaning rod assembly 3 and the bracket assembly 1, the structure of the bracket assembly 1 facilitates the three cleaning members provided thereon to be respectively adapted to the dust cup 10 or the filter assembly 4 to be cleaned. Moreover, the structure of the cleaning rod assembly 3 is simple and reasonable, facilitating user operation.

[0055] In some embodiments, as Figure 4As shown, the filtering assembly 4 includes a filtering bracket 43, a primary filter 41, and a secondary filter 42. The filtering bracket 43 has a generally cylindrical structure. The secondary filter 42 is columnar (which is the main part for realizing filtration) and is disposed inside the filtering bracket 43. The primary filter 41 is a cylindrical shape with both ends open. The primary filter 41 is disposed on the filtering bracket 43 and, together with the filtering bracket 43, is sleeved outside the secondary filter 42. The filtering bracket 43 is used to support the primary filter 41. An annular gap 44 is formed between the primary filter 41 and the secondary filter 42. The garbage and / or dust inhaled into the dust cup 10 first pass through the primary filter 41. The primary filter 41 is responsible for filtering and recovering larger garbage and / or dust particles. The garbage and / or dust filtered by the primary filter 41 then pass through the secondary filter 42. The secondary filter 42 is responsible for filtering and cleaning and recovering fine garbage and / or dust particles.

[0056] Exemplarily, the primary filter 41 can adopt a filtering steel mesh, and the secondary filter 42 can adopt a HEPA filter.

[0057] In some embodiments, as Figure 3 shown, the dust cup 10 is generally cylindrical. As Figure 1 and Figure 2 shown, the outer peripheral surface of the first frame body 11 has an approximately cylindrical surface adapted to the inner wall of the dust cup 10.

[0058] During use, the dust cup 10 is generally vertically disposed as Figure 5 and Figure 6 shown. The cleaning mechanism is disposed inside the dust cup 10 and can move up and down inside the dust cup 10. The cleaning mechanism has two extreme positions during the up and down movement. The two extreme positions are respectively the initial position at the high position and the cleaned position at the low position. When the dust cup 10 is used for cleaning operations on the cleaning device, the cleaning mechanism is in the initial position. The first frame body 11, the second frame body 12, and the three cleaning members of the cleaning mechanism are all at positions near the top end of the dust cup 10 (see Figure 5 ), and it does not perform the dust collection operation of the dust cup 10 (the dust collection operation belongs to the prior art and is not specifically introduced in this application). The rod body 31 of the cleaning rod assembly 3 is completely disposed inside the dust cup 10 and is close to the inner wall of the dust cup 10. The manual handle 33 protrudes from the bottom of the dust cup 10. When the dust collection operation is completed, or when the dust cup 10 is filled with garbage and dust, after pouring out the garbage and dust in the dust cup 10, pull down the manual handle 33. The manual handle 33 drives the bracket assembly 1 and the cleaning assembly 2 disposed on the bracket assembly 1 to move downward together through the rod body 31 until the three cleaning members all move to the bottom end of the filtering assembly 4, that is, the cleaning mechanism reaches the cleaned position (see Figure 6) During the downward movement of the cleaning mechanism, the three cleaning members of the cleaning assembly 2 respectively perform a comprehensive cleaning on the inner wall of the dust cup 10 and the two filters to remove attached dirt such as dust.

[0059] As Figures 1 to 3 shown, an annular dust seal plate 5 is provided on the cleaning rod assembly 3, and the dust seal plate 5 can move with the cleaning rod assembly 3 to close or open the lower port of the annular gap 44 between the primary filter 41 and the secondary filter 42.

[0060] In the prior art, a seal is fixed at the bottom of the filter assembly 4 to form a seal for its primary filtration (removal of large particles) and secondary filtration (removal of fine dust particles), and the primary and secondary filters are separated and filtered respectively. If the filter assembly 4 needs to be self-cleaned, the seal can only be opened by suction or thrust to clean the dust adsorbed in its primary and secondary filters, which is very inconvenient. In the present application, the dust seal plate fixed on the cleaning mechanism seals and isolates the primary filter 41 and the secondary filter 42. When the cleaning device works to clean the ground, etc., the cleaning mechanism is in the initial position, and the dust seal plate 5 closes the lower port of the annular gap 44 (see Figure 5 ), the filter assembly 4 is in a sealed state, and the filter assembly 4 is used to filter the cleaned garbage and / or dust when the cleaning device performs the dust suction work; when the dust suction is completed and the garbage and / or dust in the dust cup 10 are poured out (the garbage and / or dust in the dust cup 10 can also directly fall into the dust collection chamber when the cleaning device returns to the dust collection station), when the dust cup 10 and the filter assembly 4 are self-cleaned, the dust seal plate will move downward together with the cleaning mechanism. At this time, the bottom of the filter assembly 4 is in an open state (see Figure 6 ), and the cleaning mechanism performs up-and-down self-cleaning on the primary filter 41 and the secondary filter 42, and the cleaned dust can directly fall to the bottom of the dust cup 10 (if the cleaning device includes a dust collection station, the dust will directly enter the dust collection chamber of the dust collection station through the bottom of the dust cup 10 for collection), without falling dust by opening the seal.

[0061] Continuing to combine Figure 2 , the first end of the rod body 31 is fixed to the first side of the connecting member 32. The second side of the connecting member 32 opposite to the first side is connected to a downward-extending connecting arm 51. The connecting arm 51 is parallel to the rod body 31. The lower end of the connecting arm 51 is connected to the outer periphery of the upper end surface of the dust seal plate 5. When the connecting member 32 is fixed to the first frame body 11, the first side of the connecting member 32 is farther away from the third cleaning member 23 than its second side. The second frame body 12 is arranged on the second side of the connecting member 32. This structural layout is reasonable and is conducive to the arrangement of the dust seal plate 5.

[0062] Due to the presence of the first cleaning member 21, there is a certain gap between the outer peripheral surface of the first frame body 11 and the inner wall of the dust cup 10, that is, there is a virtual position, which will cause the cleaning mechanism to shift during the up and down movement, and cause a large friction with the inner wall of the dust cup 10, increasing the resistance of the cleaning mechanism to move and resulting in a decline in the cleaning effect. In order to prevent the cleaning mechanism from shifting and increasing friction during the up and down movement, in this embodiment, a pulley guiding mechanism 6 is provided on the outer peripheral wall of the first frame body 11, and the first frame body 11 is in rolling contact with the inner wall of the dust cup 10 through the pulley guiding mechanism 6. Refer to Figure 5 and Figure 7 . By providing the pulley guiding mechanism 6 on the first frame body 11, the virtual position of the first frame body 11 with respect to the inner wall of the dust cup 10 can be reduced, thereby reducing the friction between the cleaning mechanism and the inner wall of the dust cup 10 during the up and down movement, and making the movement of the cleaning mechanism smooth and stable.

[0063] In some embodiments, as Figure 8 shown, the pulley guiding mechanism 6 includes a fixed cover 61 and two pulleys 62 provided on the fixed cover 61. The two pulleys 62 are arranged vertically on the fixed cover 61 and can rotate relative to the fixed cover 61. As Figure 2 shown, a plurality of assembly grooves 112 are provided around the circumference of the first frame body 11. The cleaning mechanism includes a plurality of pulley guiding mechanisms 6, and the plurality of pulley guiding mechanisms 6 are respectively provided on the plurality of assembly grooves 112, and the fixed cover 61 covers the notch of the assembly groove 112. A part of the pulley 62 is located in the assembly groove 112, and the other part passes through the fixed cover 61 and is exposed outside the assembly groove 112 and contacts the inner wall of the dust cup 10. Refer to Figure 1 . By providing the pulley guiding mechanism 6, the amount of friction between the first frame body 11 and the inner wall of the dust cup 10 can be reduced, avoiding abrasions and scratches on the inner wall of the dust cup 10, and at the same time reducing the gap between the first frame body 11 and the inner wall of the dust cup 10, so that the cleaning mechanism can maintain a certain level during the cleaning process and move up and down smoothly during the cleaning process.

[0064] The fixed cover 61 can be fixed to the assembly groove 112 by means of cooperation between a clamping groove and a clamping buckle. Specifically, clamping buckles can be provided on the peripheral side of the fixed cover 61, and corresponding clamping grooves are provided on the groove wall of the assembly groove 112. When the fixed cover 61 covers the assembly groove 112, the clamping buckles are clamped in the clamping grooves.

[0065] In addition to driving the entire cleaning mechanism to move up and down to clean the dust cup 10 and the filter assembly 4 by manually pushing and pulling the manual handle 33, the cleaning mechanism of the present application can also be driven to move up and down in an electric manner. By adopting the electric driving method, the participation of manual labor can be reduced, the degree of automation is high, and the labor intensity is reduced.

[0066] As Figure 9As shown in the figure, a power drive mechanism for driving the cleaning rod assembly 3 is provided on the cleaning device or the dust cup 10. Exemplarily, the power drive mechanism includes a motor 71, a gear 72, a rack 73, and an electromagnet 74. The gear 72 is provided on the output shaft of the motor 71 and rotates when the motor 71 is started. The rack 73 is vertically provided on the cleaning device outside the dust cup 10. The bottom end of the rack 73 bends towards the dust cup 10 and extends below the bottom of the dust cup 10. The gear 72 meshes with the rack 73. An induction element 76 is provided on the cleaning device, and the induction element 76 is located above the rack 73. The electromagnet 74 is fixed to the part of the rack 73 at the bottom of the dust cup 10. A iron sheet 75 is provided at the bottom end of the rod body 31 of the cleaning rod assembly 3, and the iron sheet 75 is arranged opposite to the electromagnet 74.

[0067] Power drive is adopted, which is especially suitable for the situation where the cleaning device returns to the dust collection station to recycle garbage and / or dust after cleaning. Because the bottom of the dust cup 10 will be connected to the head of the dust collection station, it is not convenient to operate the manual handle 33. When the cleaning device returns to the dust collection station to recycle garbage and / or dust, the power drive mechanism can be provided on the head of the dust collection station. When the dust cup 10 is connected to the head of the dust collection station, the iron sheet 75 is located above and close to the electromagnet 74.

[0068] When the cleaning device returns to the dust collection station, the dust collection station first automatically recycles the garbage and / or dust in the dust cup 10 (i.e., the garbage in the dust cup 10 enters the dust collection chamber of the dust collection station). After the automatic recycling is completed, the electromagnet 74 is energized and attracts the iron sheet 75 (see Figure 9 ). The motor 71 is started and begins to drive the gear 72 to reverse. The gear 72 meshes with the rack 73, driving the rack 73 to move downward. The cleaning mechanism also moves downward for cleaning through the attraction between the iron sheet 75 and the electromagnet 74. The pulley guiding mechanism 6 slides downward through the friction between the pulley 62 and the inner wall of the dust cup 10. When the motor 71 drives the gear 72 to rotate to a set angle, at this time the cleaning mechanism is in the post-cleaning position, and all three cleaning parts are located at the bottom end of the filter assembly 4. The motor 71 starts to rotate forward, the gear 72 drives the rack 73 to move upward, and at the same time the cleaning mechanism starts to move upward for cleaning. The pulley guiding mechanism 6 slides upward through the friction between the pulley 62 and the inner wall of the dust cup 10. When the rack 73 moves upward to its top end and triggers the induction element 76, the induction element 76 changes from open to closed, and the motor 71 stops rotating forward. The electromagnet 74 is de-energized and loses the coupling effect with the iron sheet 75, and the cleaning mechanism returns to the initial position, and the self-cleaning work is completed once. According to needs, the above reciprocating cycle can be carried out multiple times to achieve multiple cleanings.

[0069] The first frame body 11 can be used as a recycling air duct. The garbage and / or dust recycled during the operation of the cleaning device enters the filter assembly 4 through the recycling air duct.

[0070] The embodiment of the present application further provides a cleaning device. As Figures 10 to 12 shown, the cleaning device includes a handle assembly 20, a dust cup assembly 30, and a floor brush assembly 40. The floor brush assembly 40 is connected to the handle assembly 20. Specifically, the floor brush assembly 40 can be connected to the handle assembly 20 through an extension tube assembly 50. The dust cup assembly 30 is disposed on the handle assembly 20 and is in communication with the floor brush assembly 40. The dust cup assembly 30 includes a dust cup 10, a filter assembly 4 disposed in the dust cup 10, and the cleaning mechanism in any of the above embodiments. The cleaning mechanism is used to clean the inner wall of the dust cup 10 and the filter assembly 4. Since the cleaning device of this embodiment has a cleaning mechanism, it can clean the dust cup 10 from which garbage and / or dust have been poured out and the filter assembly 4 inside the dust cup 10 without removing the filter assembly 4 for cleaning, thus avoiding the problems of environmental pollution and dust generation caused by removing the filter assembly 4.

[0071] When the cleaning device works, the suction motor and the floor brush drive motor (not shown in the figure) on the handle assembly 20 are started simultaneously. The floor brush assembly 40 sweeps the dust and garbage on the ground to the recovery port of the extension tube assembly 50. The suction motor on the handle assembly 20 transmits the dust and garbage from the recovery channel of the extension tube assembly 50 to the dust cup assembly 30 through suction, Figure 11 and the arrow direction in the figure indicates the flow direction of the recycled garbage. After the cleaning of the ground is completed, when the cleaning device is placed back in the dust collection station, the suction motor of the dust collection station starts to operate, and the negative pressure generated by suction sucks the dust and garbage inside its dust cup 10 into the dust collection chamber together, so as to achieve the dust collection function of its dust cup 10.

[0072] The above description is intended to be illustrative rather than restrictive. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more of their solutions) can be used in combination with each other, and considering these embodiments, they can be combined with each other in various combinations or arrangements.
