Referring to fig. 1, an embodiment of the present application provides a rolling brush mechanism 100, which includes a rolling brush body 10 and an air blowing assembly 30 (as shown in fig. 5), wherein the air blowing assembly 30 is configured to generate an air flow on a circumferential surface of the rolling brush body 10.

The rolling brush mechanism 100 can be used for an acarid killing device 200, wherein a rolling brush body 10 is installed at the bottom of a main machine 210 of the acarid killing device 200, a bottom shell 211 of the main machine 210 is formed with a mounting groove, the rolling brush body 10 is installed in the mounting groove, and two ends of the rolling brush body are rotatably connected with the bottom shell 211 through bearings. To achieve its normal operation, the rolling brush mechanism 100 further includes a rolling brush motor 50 (as shown in fig. 5), where the rolling brush motor 50 is disposed inside the host 210 and is in transmission connection with the rolling brush body 10 through a transmission mechanism. The roll brush motor 50 is used to drive the roll brush body 10 to rotate for cleaning.

It will be appreciated that the roll brush body 10 may also be used in other cleaning devices that perform cleaning by a roll brush, such as: the sweeper, scrubber, etc., are not particularly limited herein.

The circumferential surface of the rolling brush body 10 is the circumferential surface of the rolling brush body 10 surrounding the axial direction, and the air blowing component 30 can generate air flow on the circumferential surface of the rolling brush body 10 when the rolling brush body 10 rotates to work. The circumferential surface of the rolling brush body 10 around the axial direction is a surface for contacting the surface of the cleaning object to perform cleaning work. The air flow generated by the air blowing assembly 30 may cover a partial area of the circumferential surface of the roll brush body 10, or may cover the entire circumferential surface sufficiently. The air blowing assembly 30 generates an air flow at the circumferential surface of the roll brush body 10, which may include an air flow generated by blowing air along the circumferential surface of the roll brush body 10 and/or toward the circumferential surface of the roll brush body 10, and may also include an air flow generated by blowing air from the inside of the roll brush body 10 through the roll brush body 10 to the outside of the roll brush body 10.

In the above-mentioned rolling brush mechanism 100, the air blowing assembly 30 generates an air flow on the surface of the rolling brush body 10, and the air flow can form a layer of air film on the rolling brush body 10, so that the adhesion between the surface of the rolling brush body 10 and dust such as hair can be reduced, or the desorption force is generated on the dust such as hair on the rolling brush body 10, so as to promote the separation of the rolling brush body 10. In this way, the air blowing assembly 30 generates air flow on the circumferential surface of the rolling brush body 10, and can be used as a layer of air separation layer on the circumferential surface of the rolling brush body 10 to separate dust such as hair from the rolling brush body 10 or promote the dust such as hair to be separated from the rolling brush body 10, so that the probability of winding the rolling brush body 10 is reduced. In the use process, the hair on the rolling brush mechanism 100 is easy to suck and remove, easy to clean and difficult to stall, and the use experience of a user is improved.

Further, the air blowing assembly 30 is configured to generate an air flow flowing along the circumferential surface of the roll brush body 10 at the circumferential surface of the roll brush body 10.

The air flow along the circumferential surface of the roll brush body 10 may be generated by blowing air along the circumferential surface of the roll brush body 10 by the air blowing assembly 30. In addition, the air blowing assembly 30 may include a flow guiding structure 31 for guiding the flow direction of the air flow generated therefrom. The flow along the circumferential surface of the roll brush body 10 may be either in the axial direction thereof (corresponding to the direction perpendicular to the paper surface in fig. 3 and the left-right direction in fig. 8) or in the circumferential surface of the roll brush body 10 around the axial direction thereof, and the flow direction may be opposite to the rotation direction of the roll brush body 10. It will be understood that the direction of flow of the air flow refers to the direction in which it is generated, and during its flow, the resultant direction of flow of the air flow is not necessarily the same as the direction in which it is generated, subject to external disturbances.

The air flow flowing along the circumferential surface of the rolling brush body 10 can more efficiently form an air film on the circumferential surface of the rolling brush body 10 to exert the effect of reducing the probability that the rolling brush body 10 is wound. In addition, the air film formed by the air flow flowing along the circumferential surface of the rolling brush body 10 separates the surface of the rolling brush body 10 from dust such as hair, and helps to control the air flow within a small range by controlling the thickness of the air film while reducing the adhesion between the surface of the rolling brush body 10 and the dust such as hair.

Still further, the air blowing assembly 30 is configured to generate an air flow flowing in the axial direction thereof at the circumferential surface of the roll brush body 10.

The air flow flowing along the axial direction of the circumferential surface of the roll brush body 10 may be either air flow flowing from one end to the other end in the axial direction of the roll brush body 10 or air flow flowing from both ends to a position between both ends in the axial direction of the roll brush body 10.

The axial flow along the roll brush body 10 is easier to fully cover the entire circumferential surface for cleaning on the one hand, and on the other hand, the axial flow along the roll brush body 10 is a straight flow, which is easier to realize and has a lower degree of dependence on the flow guiding structure 31.

In addition, the cleaning apparatus such as the mite removal instrument 200 generally has a complete machine air duct 212, and a dust suction opening I is formed at the connection between the end of the complete machine air duct 212 and the bottom shell 211, and in consideration of the suction requirement, the dust suction opening I often does not cover the whole rolling brush body 10, but is located between two ends of the rolling brush body 10 in the axial direction. In this way, the air flow flowing along the axial direction of the rolling brush body 10 can blow the dust and dirt at the end of the rolling brush body 10 towards the middle, so that the dust and dirt is sucked by the dust suction opening I after approaching the dust suction opening I, and the dust and dirt collection is promoted.

Referring to fig. 2 to 4, in some embodiments, the air blowing assembly 30 forms an air blowing opening O toward the other end at least one of the two ends of the roller brush body 10 in the axial direction. In the axial direction of the roll brush body 10, the projection of the air blowing port O is at least partially outside the projection range of the roll brush body 10.

It will be appreciated that each of the air-blowing ports O is located outside one end of the roll brush body 10 in the axial direction and toward the other end in the axial direction of the roll brush body 10, and the air flow of the air blowing thereof flows from one end of the roll brush body 10 toward the other end, i.e., the air-blowing port O generates an air flow flowing in the axial direction thereof at the circumferential surface of the roll brush body 10. The projection of the air-blowing opening O is at least partially outside the projection range of the roll brush body 10, in other words, on the neck of the roll brush body 10, the air-blowing opening O is at least partially higher than the peripheral surface of the roll brush body 10.

In the radial direction of the rolling brush body 10, the projection of the dust collection opening I of the air duct 212 of the whole machine is located between two ends of the rolling brush body 10 in the axial direction, in other words, the projection of the dust collection opening I to the rolling brush body 10 along the radial direction of the rolling brush body 10 is located between two ends of the rolling brush body 10. Preferably, the air blowing assembly 30 forms an air blowing port O toward the other end at both ends of the roll brush body 10 in the axial direction.

Because the end of the rolling brush body 10 is far away from the dust collection port I, the influence of the suction force of the dust collection port I is smaller, and because dust such as hair is easy to move and gather in a directional manner in the rotating process of the rolling brush body 10, the two ends of the rolling brush body 10 are particularly easy to wind. An air blowing port O is formed at least one end in the axial direction of the roll brush body 10, and the air blowing port O is at least partially higher than the peripheral surface of the roll brush body 10, and an air flow blown out from the air blowing port O flows from one end toward the other end of the roll brush body 10 on the peripheral surface of the roll brush body 10. During the air flow, dust such as hair at the end can be carried toward the middle of the rolling brush body 10 and continuously approaches the dust collection port I until being sucked by the dust collection port I.

Further, the air blowing port O is annular coaxially arranged with the rolling brush body 10, and the outer diameter of the air blowing port O is larger than the diameter of the rolling brush body 10.

The inner diameter of the air blowing opening O may be between 90% and 110% of the diameter of the roll brush body 10, and may be specifically equal to the diameter of the roll brush body 10.

The air flow blown out by the annular air blowing port O can fully cover the rolling brush body 10 in the circumferential direction around the axial direction of the rolling brush body 10, and the circumferential surface of the rolling brush body 10 is blown to form a layer of air film.

Referring to fig. 5 to 7, in some embodiments, the roller brush body 10 includes a first roller brush 11 and a second roller brush 13, and the first roller brush 11 and the second roller brush 13 are coaxial and are spaced apart in an axial direction. The air blowing assembly 30 forms air blowing ports O at both ends of the first and second rolling brushes 11 and 13 opposite to each other in the axial direction, respectively. The first roller brush 11 and the second roller brush 13 are arranged at intervals corresponding to the dust collection port I of the main machine 210.

The rolling brush body 10 further includes a rotating shaft 15, and the first rolling brush 11 and the second rolling brush 13 can be respectively connected with the bottom shell 211 in a cantilever manner through one rotating shaft 15 in a rotating manner. In other embodiments, the first rolling brush 11 and the second rolling brush 13 may share the same rotating shaft 15 and are disposed on the rotating shaft 15 at intervals.

The air blowing assembly 30 is formed into two air blowing openings O, one of which is located outside the end of the first roller brush 11 facing away from the second roller brush 13 and axially toward the other end of the first roller brush 11. The other air blowing port O is positioned outside one end of the second rolling brush 13 facing away from the first rolling brush 11 and axially faces the other end of the second rolling brush 13.

The air flow blown by the air blowing ports O formed at the opposite ends of the first and second rolling brushes 11 and 13 of the air blowing assembly 30 can flow along the circumferential surfaces from one ends of the first and second rolling brushes 11 and 13, and can promote the movement of dust such as hair on the circumferential surfaces, and when moving to the other ends of the first and second rolling brushes 11 and 13, the air flow is separated from the first and second rolling brushes 11 and 13, thereby thoroughly releasing the winding of the rolling brush body 10. The main unit 210 can promote dirt such as hair to be separated from the first and second roller brushes 11 and 13 through the dust collection port I, and suck and collect dirt such as hair separated from the first and second roller brushes 11 and 13.

Referring to fig. 8 and 9, in some embodiments, the air blowing assembly 30 includes a guide structure 31 and an air flow generating device 33, wherein an air blowing cavity Q is formed in the guide structure 31, and an air inlet J and an air blowing port O are formed in communication with the air blowing cavity Q, and the air flow generating device 33 is in communication with the air inlet J of the guide structure 31 and configured to blow air from the air blowing port O to the outside through the air inlet J via the air blowing cavity Q.

The air flow generating device 33 may be, but not limited to, an air blowing motor, a fan, a high-pressure air source, etc., and may be disposed in the main unit 210, and the air flow generated by the air flow generating device 33 reaches the air blowing port O located outside the end of the roll brush body 10 under the guidance of the flow guiding structure 31.

The first rolling brush 11 and the second rolling brush 13 may share a guiding structure 31 and an airflow generating device 33, where the guiding structure 31 extends to the outer sides of the ends of the first rolling brush 11 and the second rolling brush 13, respectively, and forms two air blowing ports O. The air flow generated by the air flow generating device 33 enters the air inlet J and reaches the two air outlets O under the guidance of the flow guiding structure 31. In other embodiments, the air flow generating device 33 may be disposed corresponding to two ends of the rolling brush body 10, and two air flow generating devices 33 are disposed on two outer sides of the rolling brush body 10 respectively, and directly form the air blowing port O, that is, two outer sides of opposite ends of the first rolling brush 11 and the second rolling brush 13 are respectively provided with one air flow generating device 33, which is not limited herein.

The flow guiding structure 31 can guide the air flow generated by the air flow generating device 33 to flow through the air blowing cavity Q therein, and form an air blowing port O at the end of the roll brush body 10. Furthermore, the flow guiding structure 31 enables a more flexible mounting position of the airflow generating device 33.

Further, the flow guiding structure 31 is partially disposed on the circumferential side of the rolling brush body 10 around the axial direction, and forms an overflow gap G with the rolling brush body 10 in the radial direction thereof. In the axial direction of the roll brush body 10, the projection of the air blowing opening O is at least partially within the projection range of the overcurrent gap G.

It will be appreciated that, in order to ensure that part of the peripheral surface of the roller brush body 10 is normally in contact with the surface of the cleaning object, the flow guide structure 31 surrounds part of the peripheral side of the roller brush body 10. The cross section of the over-flow gap G in the axial direction is a part of a ring shape, the outer diameter of the air blowing port O may be not larger than the outer diameter of the over-flow gap G, the inner diameter of the air blowing port O may be not smaller than the inner diameter of the over-flow gap G, and the air blowing port O is directed toward the over-flow gap G.

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

Further, the flow guiding structure 31 includes Zhou Ke a 311 and end shells 313, zhou Ke a 311 disposed on the circumferential side of the rolling brush body 10 around the axial direction, and the end shells 313 are disposed at two ends of the rolling brush body 10 in the axial direction. The peripheral case 311 includes peripheral cases 3111 and Zhou Nake 3113, and the peripheral cases 3111 and Zhou Nake 3113 are spaced apart in the radial direction of the roll brush body 10 to form a part of the blowing chamber Q. The end housing 313 includes an end outer housing 3131 and an end inner housing 3133, the end outer housing 3131 and the end inner housing 3133 being axially spaced apart to form another portion of the blow cavity Q. The intake port J is formed in the peripheral outer housing 3111, and the blow port O is formed in the end inner housing 3133.

It can be understood that one of Zhou Ke, which is closer to the roller brush body 10, is Zhou Nake, 3113, which is farther from the roller brush body 10, is a peripheral outer housing 3111, and one of the end housings 313, which is closer to the roller brush body 10, is an end inner housing 3133, and the other is an end outer housing 3131, which is farther from the roller brush body 10. Zhou Nake 3113 forms an overcurrent gap G with the roll brush body 10 at a radial interval.

Both ends of Zhou Ke are communicated with end shell 313, peripheral outer shells 3111, zhou Nake 3113, end outer shell 3131 and end inner shell 3133 are jointly surrounded to form a blowing chamber Q, wherein end inner shell 3133 can be integrally connected with Zhou Nake 3113, peripheral inner shell 3113 is integrally connected with peripheral outer shell 3111 through a transition portion, and end outer shell 3131 is mounted at both ends in an assembled form. The air flow generated by the air flow generating device 33 enters the air blowing chamber Q through the air inlet J on the peripheral outer casing 3111, flows to both ends of the peripheral outer casing 311 in the air blowing chamber Q, enters the end casing 313, and finally is blown out through the air blowing openings O of the end inner casings 3133 at both ends.

In this way, the rolling brush mechanism 100 may form the air blowing port O at the end of the rolling brush body 10 through the flow guiding structure 31, and the air flow generating device 33 located between the two ends of the rolling brush body 10 generates the air flow blown out from the end of the rolling brush body 10 through the flow guiding structure 31. In addition, one roll brush body 10 may transmit air flow to both ends through the air blowing chamber Q and blow out from the air blowing ports O at both ends.

In some embodiments, the air blowing assembly 30 further includes a shock pad 35 and an air blowing duct 37, the air outlet end of the air flow generating device 33 is communicated with the shock pad 35, and is communicated with the air blowing duct 37 through the shock pad 35, and the air blowing duct 37 is communicated with the air inlet J.

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

The shock pad 35 can reduce the influence of vibration generated by the airflow generating device 33 during operation on the stability of airflow transmission, and the air blowing duct 37 can generate a certain rectifying effect on airflow and transmit the airflow into the diversion structure 31 through the bottom shell 211.

In the above-mentioned rolling brush mechanism 100, the air flow generating device 33 generates air flow, which sequentially passes through the shock pad 35 and the air blowing duct 37, and enters the air blowing chamber Q through the air inlet J on the peripheral outer casing 3111 of the air guiding structure 31, and flows into the end casings 313 located at both ends of the peripheral outer casing 311 in the air blowing chamber Q, and finally, the air blowing openings O of the end inner casing 3133 blow from both ends of the rolling brush body 10 to the middle of the rolling brush body 10. The air flow blown out from the air blowing ports O at the two ends can form a layer of air film on the peripheral surfaces of the first rolling brush 11 and the second rolling brush 13 respectively, can reduce the adhesion force between the surface of the rolling brush body 10 and the hair and other miscellaneous dirt, and can also blow the hair and other dust and dirt to move towards one end far away from the air blowing ports O until the dust and dirt are separated from the first rolling brush 11 and the second rolling brush 13 and sucked by the dust suction ports I. In this way, the air blowing assembly 30 generates an air flow on the circumferential surface of the rolling brush body 10, and can be used as a gas separation layer on the circumferential surface of the rolling brush body 10 to separate dust such as hair from the rolling brush body 10 or promote the dust such as hair to be separated from the rolling brush body 10, so that the probability of winding the rolling brush body 10 is reduced, and meanwhile, the dust such as hair is promoted to move towards the middle to be close to the dust collection opening I until the dust is separated from the rolling brush body 10 and sucked by the dust collection opening I. In the use process, the hair on the rolling brush mechanism 100 is easy to suck and remove, easy to clean and difficult to stall, and the use experience of a user is improved.

The application also provides cleaning equipment comprising the rolling brush mechanism 100.

Further, the cleaning apparatus further includes a main unit 210, and the main unit 210 is formed with a complete machine air duct 212. In the radial direction of the roller brush body 10, the projection center of the dust collection opening I of the air duct 212 of the whole machine is located in the interval range between the first roller brush 11 and the second roller brush 13.

In other words, the dust collection port I is projected toward the brush body 10 in the radial direction of the brush body 10, and the center of the projection is located in the interval region between the first and second brushes 11 and 13.

When dust such as hair is blown to one end of the first and second rolling brushes 11 and 13 which are close to each other by the air flow on the surface of the rolling brush body 10, on the one hand, the dust such as hair can be separated from the first and second rolling brushes 11 and 13 at the space between the first and second rolling brushes 11 and 13, and on the other hand, the suction force generated by the dust suction opening I near the space region between the first and second rolling brushes 11 and 13 can promote the dust such as hair to be separated from the first and second rolling brushes 11 and 13 and can directly suck the separated dust such as hair.

Further, the cleaning device is an acarid eliminator 200.

The mite removing instrument 200 is used for dust collection and mite removal of textiles and the like. It will be appreciated that in other embodiments, the cleaning apparatus may also be a sweeper, scrubber, or the like, and is not specifically limited herein.
