Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and particularly to a roller brush mechanism and a cleaning device. Background Art

[0002] A mite removal vacuum cleaner, also known as a mite removal device, is a cleaning device used to clean allergens such as dust and mites on textile items such as beds, sofas, carpets, and clothes. A mite removal cleaning device generally includes a cleaning main body and a holding handle. The cleaning main body is generally composed of components such as a roller brush, a dust suction port, a dust cup, and a motor. When using the mite removal vacuum cleaner for cleaning, the dust mites slapped up by the roller brush are sucked into the dust cup through the dust suction port to achieve the purpose of cleaning.

[0003] However, when the roller brush is running, dust and dirt such as hair in the cleaning area will wrap around the surface of the roller brush. As the roller brush rotates, the hair will become tighter and more accumulated, resulting in the inability to suck up the hair and making it difficult to clean the roller brush. There is also a possibility that the hair accumulates on the bearing, causing the roller brush to stop rotating. Summary of the Invention

In this way, the air flow generated by the blowing component on the surface of the roller brush body can serve as a gas separation layer on the circumferential surface of the roller brush body, separating dust and dirt such as hair from the roller brush body or promoting the separation of dust and dirt such as hair from the roller brush body, reducing the probability of the roller brush body being wrapped. During use, the hair on the roller brush mechanism is easily sucked up and cleaned, and it is not easy to stop rotating, which helps to improve the user experience.

[0041] See also Figure 1 An embodiment of the present application provides a roller brush mechanism 100, comprising a roller brush body 10 and a blowing assembly 30 (eg Figure 5 As shown), the air blowing assembly 30 is configured to generate airflow on the circumferential surface of the roller brush body 10.

[0042] The roller brush mechanism 100 can be used in a mite removal device 200, wherein the roller brush body 10 is installed at the bottom of the host 210 of the mite removal device 200. The bottom shell 211 of the host 210 is formed with a mounting groove, and the roller brush body 10 is installed in the mounting groove. The two ends are rotatably connected to the bottom shell 211 through bearings. In order to realize its normal operation, the roller brush mechanism 100 also includes a roller brush motor 50 (such as Figure 5 As shown in FIG, the roller brush motor 50 is disposed inside the main unit 210 and is connected to the roller brush body 10 via a transmission mechanism. The roller brush motor 50 is used to drive the roller brush body 10 to rotate for cleaning.

[0043] Understandably, the roller brush body 10 can also be used in other cleaning devices that use a roller brush for cleaning, such as a floor sweeper, a floor washer, etc., and specific limitations are not made here.

[0044] The circumferential surface of the roller brush body 10 is the circumferential surface of the roller brush body 10 surrounding the axial direction. The air blowing assembly 30 can generate an air flow on its circumferential surface when the roller brush body 10 rotates and works. Among them, the circumferential surface of the roller brush body 10 surrounding the axial direction is the surface used to contact the surface of the cleaning object for cleaning work. The air flow generated by the air blowing assembly 30 can cover a partial area of the circumferential surface of the roller brush body 10, or can fully cover the entire circumferential surface. The air blowing assembly 30 generating an air flow on the circumferential surface of the roller brush body 10 can include the air flow generated by blowing air along the circumferential surface of the roller brush body 10 and / or blowing air towards the circumferential surface of the roller brush body 10, and can also include the air flow generated by blowing air from inside the roller brush body 10 through the roller brush body 10 to the outside of the roller brush body 10.

[0045] For the above-mentioned roller brush mechanism 100, an air flow is generated on the surface of the roller brush body 10 by the air blowing assembly 30. This air flow can form an air film on the roller brush body 10, which can reduce the adhesion force between the surface of the roller brush body 10 and dust and dirt such as hair, or generate a desorption force on the hair and other dust and dirt on the roller brush body 10, promoting its separation from the roller brush body 10. In this way, the air flow generated by the air blowing assembly 30 on the circumferential surface of the roller brush body 10 can serve as a gas separation layer on the circumferential surface of the roller brush body 10, separating dust and dirt such as hair from the roller brush body 10 or promoting the separation of dust and dirt such as hair from the roller brush body 10, reducing the probability of the roller brush body 10 being entangled. During use, the hair on the roller brush mechanism 100 is easy to suck up, easy to clean, and not prone to stalling, which helps to improve the user experience.

[0046] Furthermore, the air blowing assembly 30 is configured to generate an air flow flowing along the circumferential surface of the roller brush body 10 on the circumferential surface of the roller brush body 10.

[0047] The air flow flowing along the circumferential surface of the roller brush body 10 can be generated by the air blowing assembly 30 blowing air along the circumferential surface of the roller brush body 10. In addition, the air blowing assembly 30 can include a flow guiding structure 31 to guide the flow direction of the generated air flow. The flow along the circumferential surface of the roller brush body 10 can be either flowing along its axial direction (corresponding to the direction perpendicular to the paper surface in Figure 3 and the left-right direction in Figure 8 ) on the circumferential surface of the roller brush body 10, or flowing along the circumferential direction surrounding its axial direction on the circumferential surface of the roller brush body 10, and the flow direction can be opposite to the rotation direction of the roller brush body 10. Understandably, the flow direction of the air flow refers to the direction when it is generated. During its flow process, affected by external interference, the final flow direction of the air flow is not necessarily the same as the direction when it is generated.

[0048] When the air flow flows along the circumferential surface of the roller brush body 10, an air film can be more efficiently formed on the circumferential surface of the roller brush body 10 to reduce the probability of the roller brush body 10 being entangled. In addition, the air film formed by the air flow flowing along the circumferential surface of the roller brush body 10 separates the surface of the roller brush body 10 from dust and dirt such as hair, reducing the adhesion force between the surface of the roller brush body 10 and dust and dirt such as hair, and at the same time, it helps to control the air flow within a smaller range by controlling the thickness of the air film.

[0049] Furthermore, the air blowing assembly 30 is configured to generate an air flow flowing along the axial direction on the circumferential surface of the roller brush body 10.

[0050] The air flow flowing along the axial direction on the circumferential surface of the roller brush body 10 can either flow from one end to the other end of the roller brush body 10 in the axial direction, or flow from both ends of the roller brush body 10 in the axial direction to a position between the two ends.

[0051] Flowing along the axial direction of the roller brush body 10, on the one hand, it is easier to fully cover the entire circumferential surface for cleaning, and on the other hand, the flow along the axial direction of the roller brush body 10 is a straight-line flow, which is easier to achieve and has a lower dependence on the flow guiding structure 31.

[0052] In addition, cleaning devices such as the mite remover 200 usually have a whole-machine air duct 212, and a dust suction port I is formed at the connection between the end of the whole-machine air duct 212 and the bottom shell 211. Considering the suction requirement, the dust suction port I often does not cover the entire roller brush body 10, but is located between the two ends of the roller brush body 10 in the axial direction. In this way, the air flow flowing along the axial direction of the roller brush body 10 can blow the dust and dirt located at the ends of the roller brush body 10 towards the middle, so that they are sucked into the dust suction port I after approaching the dust suction port I, to promote the collection of dust and dirt.

[0053] Please refer to Figures 2 to 4 , in some embodiments, the air blowing assembly 30 forms a blowing port O facing the other end outside at least one end of the two ends of the roller brush body 10 in the axial direction. In the axial direction of the roller brush body 10, at least part of the projection of the blowing port O is outside the projection range of the roller brush body 10.

[0054] It can be understood that each blowing port O is located outside one end of the roller brush body 10 in the axial direction and faces the other end along the axial direction of the roller brush body 10. The blowing air flow flows from one end of the roller brush body 10 towards the other end, that is, the blowing port O generates an air flow flowing along the axial direction on the circumferential surface of the roller brush body 10. At least part of the projection of the blowing port O is outside the projection range of the roller brush body 10. In other words, on the neck of the roller brush body 10, the blowing port O is at least partially higher than the circumferential surface of the roller brush body 10.

[0055] In the radial direction of the roller brush body 10, the projection of the dust suction port I of the whole machine air duct 212 is located between the two axial ends of the roller brush body 10. In other words, projecting the dust suction port I onto the roller brush body 10 along the radial direction of the roller brush body 10, the projection of the dust suction port I is located between the two ends of the roller brush body 10. Preferably, the blowing assembly 30 forms blowing ports O facing the other end at both axial ends of the roller brush body 10.

[0056] Since the ends of the roller brush body 10 are farther away from the dust suction port I and are less affected by the suction force of the dust suction port I, and since during the rotation of the roller brush body 10, dust and dirt such as hair are prone to directional movement and aggregation, therefore, the two ends of the roller brush body 10 are particularly prone to entanglement. A blowing port O is formed at at least one end in the axial direction of the roller brush body 10, and at least part of the blowing port O is higher than the peripheral surface of the roller brush body 10. The airflow blown out by the blowing port O flows on the peripheral surface of the roller brush body 10 from one end of the roller brush body 10 towards the other end. During the flow of the airflow, the dust and dirt such as hair at the end can also be carried towards the middle of the roller brush body 10, getting closer and closer to the dust suction port I until being sucked in by the dust suction port I.

[0057] Furthermore, the blowing port O is an annular shape coaxially arranged with the roller brush body 10, and the outer diameter of the blowing port O is larger than the diameter of the roller brush body 10.

[0058] The inner diameter of the blowing port O can be between 90% and 110% of the diameter of the roller brush body 10, and specifically can be equal to the diameter of the roller brush body 10.

[0059] The airflow blown out by the annular blowing port O can fully cover the roller brush body 10 in the circumferential direction around the axial direction of the roller brush body 10, purging the peripheral surface of the roller brush body 10 to form an air film.

[0060] Please refer to Figures 5 to 7 In some embodiments, the roller brush body 10 includes a first roller brush 11 and a second roller brush 13. The first roller brush 11 and the second roller brush 13 are coaxial and spaced apart in the axial direction. The blowing assembly 30 forms blowing ports O respectively outside the two axially opposite ends of the first roller brush 11 and the second roller brush 13. The spaced position between the first roller brush 11 and the second roller brush 13 is correspondingly arranged with the dust suction port I of the main machine 210.

[0061] The roller brush body 10 further includes a rotating shaft 15. The first roller brush 11 and the second roller brush 13 can be respectively rotatably connected to the bottom shell 211 in a cantilever form through a rotating shaft 15. In some other embodiments, the first roller brush 11 and the second roller brush 13 can also share the same rotating shaft 15 and be spaced apart on the rotating shaft 15.

[0062] The blowing assembly 30 forms two blowing ports O in total. One of the blowing ports O is located outside one end of the first roller brush 11 facing away from the second roller brush 13 and axially faces the other end of the first roller brush 11. The other blowing port O is located outside one end of the second roller brush 13 facing away from the first roller brush 11 and axially faces the other end of the second roller brush 13.

[0063] The airflow blown out from the blowing ports O formed by the blowing assembly 30 at the two opposite ends of the first roller brush 11 and the second roller brush 13 can each flow along the circumferential surface from one end of the first roller brush 11 and the second roller brush 13, and can promote the movement of dust and dirt such as hair on the circumferential surface. When moving to the other ends of the first roller brush 11 and the second roller brush 13, it detaches from the first roller brush 11 and the second roller brush 13, completely relieving the entanglement of the roller brush body 10. In addition, the main body 210 can promote the detachment of dust and dirt such as hair from the first roller brush 11 and the second roller brush 13 through the suction port I, and suck and collect the dust and dirt such as hair that have detached from the first roller brush 11 and the second roller brush 13.

[0064] Please refer to Figure 8 and Figure 9 In some embodiments, the blowing assembly 30 includes a diversion structure 31 and an airflow generating device 33. A blowing cavity Q is formed in the diversion structure 31, and an air inlet J and the blowing port O communicating with the blowing cavity Q are formed. The airflow generating device 33 communicates with the air inlet J of the diversion structure 31 and is configured to blow air outwards through the air inlet J through the blowing cavity Q to the blowing port O.

[0065] The airflow generating device 33 can be, but is not limited to, a blowing motor, a blower, a high-pressure air source, etc., and can be arranged in the main body 210. The airflow generated by the airflow generating device 33 reaches the blowing port O located outside the end of the roller brush body 10 under the guidance of the diversion structure 31.

[0066] The first roller brush 11 and the second roller brush 13 can share a diversion structure 31 and an airflow generating device 33. The diversion structure 31 extends to the outside of the ends of the first roller brush 11 and the second roller brush 13 respectively, and forms two blowing ports O. The airflow generated by the airflow generating device 33 enters the air inlet J and reaches the two blowing ports O respectively under the guidance of the diversion structure 31. In some other embodiments, the airflow generating device 33 can be arranged corresponding to the two ends of the roller brush body 10. There are two airflow generating devices 33 respectively arranged outside the two ends of the roller brush body 10 and directly form the blowing ports O, that is, one airflow generating device 33 is arranged outside each of the two opposite ends of the first roller brush 11 and the second roller brush 13, and no specific limitation is made here.

[0067] The air guiding structure 31 can guide the airflow generated by the airflow generating device 33 through the air blowing cavity Q therein, and form an air blowing port O at the end of the brush roller body 10. In addition, the air guiding structure 31 can also make the installation position of the airflow generating device 33 more flexible.

[0068] Furthermore, a part of the air guiding structure 31 is arranged on the circumferential side of the brush roller body 10 around its axial direction, and an overflow gap G is formed at a radial interval from the brush roller body 10. Axially of the brush roller body 10, at least a part of the projection of the air blowing port O is within the projection range of the overflow gap G.

[0069] It can be understood that to ensure that a part of the peripheral surface of the brush roller body 10 can normally contact the surface of the cleaning object, the air guiding structure 31 surrounds a part of the circumferential side of the brush roller body 10. The cross-section of the overflow gap G in the axial direction is a part of an annulus. The outer diameter of the air blowing port O may not be greater than the outer diameter of the overflow gap G, the inner diameter of the air blowing port O may not be less than the inner diameter of the overflow gap G, and the air blowing port O partially faces the overflow gap G.

[0070] The overflow gap G is formed between the air guiding structure 31 and the brush roller body 10, that is, on the circumferential surface of the brush roller body 10. The airflow blown out from the part of the air blowing port O facing the overflow gap G can flow along the axial direction of the brush roller body 10 on the circumferential surface of the brush roller body 10 under the guidance of the outer surface of the air guiding structure 31.

[0071] Furthermore, the air guiding structure 31 includes a circumferential shell 311 and end shells 313. The circumferential shell 311 is arranged on the circumferential side of the brush roller body 10 around its axial direction, and the end shells 313 are arranged at both axial ends of the brush roller body 10. The circumferential shell 311 includes a circumferential outer shell 3111 and a circumferential inner shell 3113, and the circumferential outer shell 3111 and the circumferential inner shell 3113 form a part of the air blowing cavity Q at a radial interval. The end shell 313 includes an end outer shell 3131 and an end inner shell 3133, and the end outer shell 3131 and the end inner shell 3133 form another part of the air blowing cavity Q at an axial interval. The air inlet J is formed on the circumferential outer shell 3111, and the air blowing port O is formed on the end inner shell 3133.

[0072] It can be understood that the one of the circumferential shell 311 close to the brush roller body 10 is the circumferential inner shell 3113, and the one far from the brush roller body 10 is the circumferential outer shell 3111. Similarly, the one of the end shells 313 close to the brush roller body 10 is the end inner shell 3133, and the one far from the brush roller body 10 is the end outer shell 3131. The circumferential inner shell 3113 and the brush roller body 10 form the overflow gap G at a radial interval.

[0073] Both ends of the circumferential shell 311 communicate with the end shell 313. The outer circumferential shell 3111, the inner circumferential shell 3113, the outer end shell 3131, and the inner end shell 3133 jointly enclose to form a blowing cavity Q. Among them, the inner end shell 3133 can be integrally connected to the inner circumferential shell 3113. The inner circumferential shell 3113 and the outer circumferential shell 3111 are integrally connected through a transition part. The outer end shell 3131 is installed at both ends in an assembled form. The air flow generated by the air flow generating device 33 enters the blowing cavity Q through the air inlet J on the outer circumferential shell 3111, flows in the blowing cavity Q to both ends of the circumferential shell 311 and enters the end shell 313, and finally is blown outwards through the blowing ports O of the inner end shells 3133 at both ends.

[0074] In this way, the brush roller mechanism 100 can form a blowing port O at the end of the brush roller body 10 through the flow guiding structure 31. The air flow generating device 33 located between both ends of the brush roller body 10 generates an air flow blown out from the end of the brush roller body 10 through the flow guiding structure 31. In addition, an air flow can be transmitted from one brush roller body 10 to both ends through the blowing cavity Q and blown out from the blowing ports O at both ends.

[0075] In some embodiments, the blowing assembly 30 further includes a shock pad 35 and a blowing air duct 37. The air outlet end of the air flow generating device 33 communicates with the shock pad 35 and communicates with the blowing air duct 37 through the shock pad 35, and the blowing air duct 37 communicates with the air inlet J.

[0076] The air flow generating device 33 is arranged in the main machine 210 and communicates with the air inlet J on the flow guiding structure 31 installed in the installation groove below the bottom shell 211 through the blowing air duct 37 passing through the bottom shell 211.

[0077] The shock pad 35 can reduce the influence of the vibration generated by the air flow generating device 33 during operation on the stability of air flow transmission. The blowing air duct 37 can rectify the air flow to a certain extent and transmit it through the bottom shell 211 into the flow guiding structure 31.

[0078] For the above-mentioned roller brush mechanism 100, the air flow generating device 33 generates an air flow, which successively passes through the shock-absorbing pad 35 and the air blowing air duct 37 and enters the air blowing cavity Q from the air inlet J on the circumferential outer shell 3111 of the diversion structure 31. Then, it flows in the air blowing cavity Q and enters the end shells 313 at both ends of the circumferential shell 311. Finally, it blows from the air blowing ports O of the inner end shell 3133 from both ends of the roller brush body 10 towards the middle of the roller brush body 10. The air flows blown out from the two air blowing ports O can respectively form an air film on the circumferential surfaces of the first roller brush 11 and the second roller brush 13, which can reduce the adhesion force between the surface of the roller brush body 10 and sundries such as hair. At the same time, it can also blow sundries such as hair towards one end away from the air blowing port O until they are separated from the first roller brush 11 and the second roller brush 13 and are sucked into the dust suction port I. In this way, the air flow generated by the air blowing assembly 30 on the circumferential surface of the roller brush body 10 can serve as a gas separation layer on the circumferential surface of the roller brush body 10, separating sundries such as hair from the roller brush body 10 or promoting the separation of sundries such as hair from the roller brush body 10, reducing the probability of the roller brush body 10 being entangled, and at the same time promoting sundries such as hair to move towards the middle and approach the dust suction port I until they are separated from the roller brush body 10 and are sucked into the dust suction port I. During use, the hair on the roller brush mechanism 100 is easy to be sucked and cleaned, and it is not easy to stop rotating, which helps to improve the user experience.

[0079] This application also provides a cleaning device, including the above-mentioned roller brush mechanism 100.

[0080] Further, the cleaning device further includes a main body 210, and the main body 210 forms an overall air duct 212. In the radial direction of the roller brush body 10, the projection center of the dust suction port I of the overall air duct 212 is located within the interval range between the first roller brush 11 and the second roller brush 13.

[0081] In other words, when the dust suction port I is projected onto the roller brush body 10 along the radial direction of the roller brush body 10, the center of its projection is located in the interval area between the first roller brush 11 and the second roller brush 13.

[0082] When sundries such as hair are blown by the air flow on the surface of the roller brush body 10 to the end where the first roller brush 11 and the second roller brush 13 are close to each other, on the one hand, since there is an interval between the first roller brush 11 and the second roller brush 13, sundries such as hair can be separated from the first roller brush 11 and the second roller brush 13 here. On the other hand, the dust suction port I is close to the interval area between the first roller brush 11 and the second roller brush 13, and the suction force generated can promote sundries such as hair to be separated from the first roller brush 11 and the second roller brush 13 and can directly suck the separated sundries such as hair.

[0083] Further, the cleaning device is a mite remover 200.

[0084] The mite remover 200 is used for vacuuming and mite removing on textiles and the like. Understandably, in some other embodiments, the cleaning device can also be a floor sweeper, a floor washer, etc., which are not specifically limited herein.

[0085] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0086] The above-described embodiments only represent several implementation manners of the present application, and the description thereof is relatively specific and detailed, but it should not be understood as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
