Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a roller brush, a roller brush assembly and a cleaning system. Background Art

[0002] Current cleaning equipment, such as sweepers and sweep-and-mop machines, usually use a roller brush close to the ground to clean dust, particles, hair, etc. on the ground. However, when the roller brush rotates to clean, hair and other filaments are easily rolled up by the roller brush and entangled on the roller brush. For cantilever roller brushes, since the end usually needs to extend the blades axially, the root of the roller brush is often entangled with hair, and even entangled on the roller brush drive shaft, which increases the wear of the roller brush drive component, reduces the service life of the cleaning equipment, and affects the user experience.

[0056] In the detailed disclosure below, these embodiments are fully described with reference to the accompanying drawings. In order to make the technical solutions of the present invention more clear and specific to those skilled in the art, the implementation methods described below are not limited to these. The present invention is further described in detail below in combination with the embodiments and the accompanying drawings.

[0057] In this utility model, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "plurality" refers to two or more, unless expressly limited otherwise. Terms such as "installed," "connected," "connected," and "fixed" should be interpreted broadly. For example, "connected" can mean fixed, removable, or integral; "connected" can mean directly or indirectly through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0058] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by terms such as "up", "down", "left", "right", "front" and "back" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or unit referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0059] The common roller brush 100 in the prior art is usually connected to the driving device in the cabin 3 through a rotating shaft. When the roller brush 100 interferes with linear objects such as hair, due to the long length and soft material of linear objects such as hair, the long and soft hair will spontaneously form many different configurations in the natural state. After being interfered with by the roller brush 100, it is more inclined to self-entangle and easily entangled on the roller brush 100 and the rotating shaft of the roller brush 100. After long-term use, too much hair entangled on the roller brush 100 will cause the roller brush 100 to deform, and will also increase the loss of the roller brush 100 driving parts, thereby reducing the service life of the cleaning equipment. The hair entangled on the rotating shaft is not easily sucked into the air duct, affecting the cleaning efficiency, so it is necessary to manually clean the roller brush 100 and the hair on the rotating shaft regularly, which is time-consuming and labor-intensive. After the hair enters the cabin 3, it will pollute the cabin environment and even cause damage to parts in the cabin, affecting the service life of the equipment.

[0060] The first aspect of the present utility model is as follows Figures 1-12 As shown, a roller brush 100 is provided, which is used for cleaning equipment. The roller brush 100 includes a roller brush body 1 and a blocking member 2. The roller brush body 1 includes a shaft 11 and blades 12. The blades 12 are arranged on the outer peripheral side of the shaft 11; the blocking member 2 is arranged at the end of the roller brush body 1, and a part of the blade 12 is inclined toward the axial direction of the shaft 11 and inserted into the blocking member 2.

[0061] The roller brush 100 provided by the present invention is provided with an annular blocking member 2 at one end of the roller brush 100 close to the cabin body 3, and a part of the blade 12 is inclined toward the axial direction of the shaft 11 and inserted into the blocking member 2. Multiple blades 12 are provided on the shaft 11, and hair is wrapped around the multiple blades 12 to form a nearly circular hair circle. The outer diameter of the blocking member 2 is larger than the outer diameter of the multiple blades 12 connected to the blocking member 2. When the hair on the blade 12 moves toward the end in the axial direction of the roller brush body 1, the hair is blocked by the blocking member 2 and cannot be wrapped around the shaft connected to the roller brush 100, and the hair is restricted to the blades 12 with a larger outer diameter. The hair is difficult to form a ball, can be better sucked into the air duct, improve the cleaning effect, prevent the hair from escaping from the blades 12 and wrapping around the shaft, reduce the possibility of the roller brush 100 being entangled and deformed by the hair, and reduce the loss of the driving member. At the same time, the blocking member 2 is provided at one end of the roller brush 100 close to the cabin body, which can prevent the hair from entering the cabin body 3, thereby extending the service life of the device and improving the user experience.

[0062] In one possible implementation, Figure 1-Figure 4 As shown, the blade 12 includes a blade body 122 and an extension portion 121. The extension portion 121 is arranged at the end of the blade body 122. A portion of the extension portion 121 is inserted into the blocking member 2. In the radial direction of the roller brush body 1, the extension portion 121 is located on the inner side of the outer edge of the blade body 122. The extension portion 121 is located on the inner side of the outer edge of the blocking member 2.

[0063] The outer diameter of the blocking member 2 is larger than the outer diameter of the extension portion 121. When the hair on the blade 12 moves axially along the roller brush body 1, the hair moves to the position of the extension portion 121 and is slightly tightened until it contacts the blocking member 2. The hair is stopped by the blocking member 2 and cannot continue to move toward the end, which can limit the hair to the position of the extension portion 121. The diameter of the hair loop wrapped at the extension portion 121 is slightly smaller than the diameter of the hair loop wrapped on the blade body 122. The hair loop wrapped at the extension portion 121 still has a larger diameter, so that the hair cannot be entangled by itself, which greatly reduces the situation where the hair is tightly entangled on the roller brush 100, reduces the situation where the roller brush 100 is deformed due to the hair being tightly entangled on the roller brush 100, reduces the frequency of manual cleaning of the hair on the roller brush 100, and improves user satisfaction.

[0064] The radial height of at least a portion of the extending portion 121 is lower than the radial height of the blocking member 2 .

[0065] In one possible implementation, Figure 1-Figure 4 As shown, there are multiple blades 12 , which are arranged along the circumference of the shaft 11 , and the radial distance between the extension 121 and the shaft 11 is smaller than the radial distance between the outer edge of the blade body 122 and the shaft 11 .

[0066] It can be understood that the plurality of blades 12 are provided on the outer peripheral side of the shaft 11 and arranged along the circumference of the shaft 11 , and the driving device drives the shaft 11 and the blades 12 to rotate through the rotating shaft to achieve cleaning of the surface to be cleaned.

[0067] Specifically, the blades 12 may be arranged along the axial direction of the shaft 11 , or may extend in a spiral shape along the axial direction of the shaft 11 .

[0068] In one possible implementation, Figure 1-Figure 4 As shown, at least a portion of the outer edge of the extension portion 121 is a guide segment, and the guide segment is arranged between the blocking member 2 and the blade body 122 .

[0069] It can be understood that the portion of the extension 121 inserted into the blocking member 2 is smoothly connected to the blade body 122 through the guide section, that is, there is no obvious gap or break in the portion of the blade 12 between the portion of the extension 121 inserted into the blocking member 2 and the blade body 122, and the two have a smooth transition, ensuring that the hair can move stably along the blade 12 until it is stopped by the blocking member 2.

[0070] The guide segment includes an oblique line segment and / or an arc line segment.

[0071] In one possible implementation, this embodiment takes the guide section as an oblique line segment as an example, at least part of the oblique line segment is located between the blocking member 2 and the blade body 122, the oblique line segment extends from one end of the blade body 122 toward the blocking member 2 and is inserted into the blocking member 2, and the oblique line segment is inclined in the direction close to the shaft 11, so that the hair can contact the blocking member 2 when it moves from the blade body 122 to the oblique line segment position, and the hair at the oblique line segment position of the blocking member 2 moves axially along the shaft 11 to form a stop.

[0072] In one possible implementation, this embodiment takes the guide section as an arc section as an example, at least part of the arc section is located between the blocking member 2 and the blade body 122, the arc section extends from one end of the blade body 122 toward the blocking member 2 and is inserted into the blocking member 2, and the arc section is inclined toward the direction close to the shaft 11, so that the hair can contact the blocking member 2 when it moves from the blade body 122 to the arc section position, and the hair at the blocking member 2 at the arc section position moves axially along the shaft 11 to form a stop.

[0073] In one possible implementation, this embodiment takes the guide section including an arc segment and an oblique line segment as an example, at least part of the oblique line segment or at least part of the oblique line segment is located between the blocking member 2 and the blade body 122, at least one of the arc segment and the oblique line segment extends from one end of the blade body 122 toward the blocking member 2 and is inserted into the blocking member 2, at least one of the arc segment and the oblique line segment is inclined in a direction close to the shaft 11, so that the hair can contact the blocking member 2 when it moves from the blade body 122 to at least one position among the arc segment and the oblique line segment, and the hair at at least one position among the arc segment and the oblique line segment of the blocking member 2 moves axially along the shaft 11 to form a stopper.

[0074] The arc segment may be a concave arc, that is, an inwardly concave arc.

[0075] Among them, the arc segment can also be a convex arc, that is, an outward-convex arc. When the arc segment is a convex arc, the arc segment can be completely located between the blocking member 2 and the blade body 122. A transition segment can also be set between the arc segment and the blocking member 2. The transition segment can be a straight line segment, an oblique line segment, an arc segment, etc., to prevent hair from being entangled in the gap between the convex arc and the blocking member 2.

[0076] In one possible implementation, Figure 1-Figure 4 As shown, the ratio of the minimum radial distance between the guide section and the shaft 11 to the radial distance between the outer edge of the blade body 122 and the shaft 11 is 0.5 to 0.9.

[0077] 121 and is stopped by the blocking member 2.

[0078] In one possible implementation, Figure 3 and Figure 4 As shown, an end plate 13 is provided on the shaft 11 , and a plurality of blades 12 are embedded in the end plate 13 , and the blades 12 extend out of a side of the end plate 13 away from the blade body 122 , and the blocking member 2 is located on a side of the end plate 13 away from the blade body 122 .

[0079] Among them, an annular end plate 13 is provided on the shaft 11, and the end plate 13 is sleeved on the shaft 11. The end plate 13 is connected to a plurality of blade bodies 122. The root of the blade 12 is narrowed to form an extension portion 121. The extension portion 121 protrudes from the end surface of the end plate 13 and is inserted into the blocking member 2. The end of the extension portion 121 can be located in the blocking member 2 or pass through the blocking member 2.

[0080] In one possible implementation, Figure 3 and Figure 4 As shown, the shaft 11 includes a shaft body 111 and an annular flange 112 . The annular flange 112 is provided at the end of the shaft body 111 , and the blocking member 2 is sleeved on the annular flange 112 .

[0081] The shaft body 111 may be a cylindrical structure and arranged along a straight line.

[0082] Among them, the annular flange 112 is set at the end of the shaft body 111, and the blocking member 2 is sleeved on the annular flange 112. The annular flange 112 and the shaft body 111 can be an integral structure or a split structure, and the end plate 13 can be located on one side of the annular flange 112.

[0083] The blocking member 2 and the shaft 11 can be connected by means of gluing, sleeve connection, screws, snap connection, mortise and tenon joint, magnetism, etc., so that the blocking member 2 can rotate with the shaft 11.

[0084] In one possible implementation, Figure 5 As shown, the blocking member 2 includes bristle bundles 22 arranged circumferentially along the shaft 11 , and the extension portion 121 is inserted into the gaps between the bristle bundles 22 .

[0085] The hair on the blade 12 is stopped by the blocking member 2 composed of a plurality of hair bundles 22 , and small gaps are formed between the hair bundles 22 , and the extension portion 121 can be inserted into the gaps between the hair bundles 22 .

[0086] One end of the hair bundle 22 is finally connected to the shaft 11, and the other end of the hair bundle 22 contacts the inner wall of the cabin, forming a stop for the hair moving toward the interior of the cabin.

[0087] Further, if Figure 5 As shown, the blocking member 2 may further include an annular member 21 , which is sleeved on the shaft 11 , and the hair bundle 22 includes a fixed end and a free end, the fixed end is connected to the annular member 21 , and the free end extends in a direction away from the shaft 11 .

[0088] When not deformed by external force, the hair bundle 22 extends in a straight line, the fixed end of the hair bundle 22 is connected to the annular member 21, the annular member 21 is connected to the shaft 11, and the free end of the hair bundle 22 extends radially away from the shaft 11, making it difficult for hair to be entangled on the hair bundle 22.

[0089] The annular member 21 can be connected to the annular flange 112 , and the free end of the hair bundle 22 contacts the inner wall of the cabin 3 , filling the gap between the shaft 11 and the cabin 3 , so that hair cannot enter the cabin 3 .

[0090] The hair bundle 22 is elastic and can be deformed when in contact with the inner wall of the cabin 3 , so that the free end of the hair bundle 22 always fits with the inner wall of the cabin 3 .

[0091] The hair bundle 22 may be made of at least one of rubber material, plastic fiber material, inorganic fiber material, plant fiber material, and animal fiber material.

[0092] The surface of the hair bundle 22 is smooth and burr-free, which reduces the friction between the hair and the blocking member 2, allowing the hair to slide relative to the blocking member 2 and preventing the hair from being entangled on the hair bundle 22.

[0093] In one possible implementation, Figure 6 As shown, the blocking member 2 includes an annular member 21 , which is sleeved on the shaft 11 , and a groove 23 is formed on the annular member 21 for the extension portion 121 to be inserted into.

[0094] Among them, the blocking member 2 can be an annular member 21, and the extension part 121 is inserted into the groove 23 opened on the annular member 21. The groove 23 can be an open groove with one end open, or a through groove with both ends open. The groove 23 and the extension part 121 are fitted with a small gap or interference fit to prevent hair from entering the interior of the cabin 3 through the groove 23.

[0095] The inner wall of the annular member 21 is finally connected to the shaft 11 , and the outer wall of the annular member 21 extends in a direction away from the shaft 11 , forming a stop for the hair moving toward the interior of the cabin.

[0096] The annular member 21 can be connected to the annular flange 112 , and the outer wall of the annular member 21 contacts the inner wall of the cabin, filling the gap between the shaft 11 and the cabin 3 so that hair cannot enter the cabin 3 .

[0097] The annular member 21 is elastic, or the outer wall of the annular member 21 is elastic, and the annular member 21 can be deformed during contact with the inner wall of the cabin 3, so that the outer wall of the annular member 21 always fits with the inner wall of the cabin 3.

[0098] The blocking member 2 is made of felt material, which is mostly made of animal hair or fiber, and has good elasticity, sealing and wear resistance, and can also achieve a vibration reduction effect.

[0099] In one embodiment, the blocking member 2 and the shaft rod 11 may be integrally formed or may be a separate structure.

[0100] In one embodiment, the blocking member 2 and the shaft rod 11 are in a detachable structure or a fixed connection structure.

[0101] In one possible implementation, Figure 7-11 As shown, the cleaning device includes a cabin 3 for accommodating a roller brush 100 , and a blocking member 2 is located between the shaft 11 and the cabin 3 and fills the gap between the shaft 11 and the cabin 3 to form a stop for hair moving toward the gap.

[0102] In one possible implementation, Figures 8-11 As shown, there is no contact between the blade 12 and the cabin body 3 , and interference occurs between the blocking member 2 and the cabin body 3 .

[0103] It can be understood that there is a small gap fit between the extension part 121 and the cabin body 3, and an interference fit between the blocking member 2 and the inner wall of the cabin body 3, so that the blocking member 2 always fits with the inner wall of the cabin body 3 during the rotation of the roller brush body 1, thereby ensuring the sealing effect.

[0104] In one possible implementation, Figure 11As shown, at least a portion of the blocking member 2 is elastic, and during the relative movement between the blocking member 2 and the cabin body 3 , the blocking member 2 always fits with the cabin body 3 .

[0105] The second aspect of the present invention is as follows Figure 7-12 As shown, a roller brush assembly 200 is provided, comprising any roller brush 100 in the first aspect, wherein the roller brush 100 is used to be connected to a driving device so that the driving device drives the roller brush 100 to rotate.

[0106] Among them, the roller brush assembly 200 includes a cabin 3, the roller brush 100 is arranged in the cabin 3, and the driving device can be arranged in the cabin 3. The driving device is connected to the roller brush 100 through a rotating shaft, driving the roller brush 100 to rotate and interfere with the surface to be cleaned.

[0107] The cabin 3 provides good protection for the driving device and the transmission device, reduces pollution inside the cabin 3, and is beneficial to extending the service life and reliability.

[0108] In one possible implementation, Figures 8-12 As shown, the cabin body 3 includes a main brush cabin 31 and a main brush cover 32 , which together form a chamber for accommodating the roller brush 100 , and together form a matching cavity 33 for accommodating the blocking member 2 .

[0109] Specifically, the cabin body 3 may include a detachably connected main brush cabin 31 and a main brush cover 32, which is convenient for assembly, disassembly and maintenance. The brush cabin body and the main brush cover 32 can be detachably connected by at least one of screws, a snap-fit structure, a mortise and tenon structure, and a magnetic structure.

[0110] Among them, such as Figures 9-11 As shown, the cabin 3 is provided with a main brush opening 34 and a matching cavity 33 , and the blade 12 passes through the main brush opening 34 and interferes with the surface to be cleaned; the matching cavity 33 is located on the outer peripheral side of the blocking member 2 and interferes with the blocking member 2 .

[0111] The main brush compartment 31 and the main brush cover 32 enclose a chamber for accommodating the roller brush 100 . The chamber has an opening, namely a main brush opening 34 , through which a portion of the roller brush 100 passes to contact the surface to be cleaned.

[0112] Among them, the main brush cabin 31 and the main brush cover 32 are enclosed to form a matching cavity 33 for accommodating the blocking member 2. The matching cavity 33 is specifically formed by the shaft 11 and the cabin body 3. The shape of the matching cavity 33 is adapted to the shape of the blocking member 2. The shape of the matching cavity 33 is an annular cavity slightly smaller than the blocking member 2, and the outer edge of the blocking member 2 is always in contact with the matching cavity 33.

[0113] The maximum distance from the outer edge of the blade body 122 to the axis of the shaft 11 is greater than the maximum distance from the outer wall of the main brush cover 32 to the axis of the shaft 11, so that the blade body 122 can pass through the main brush opening 34 and interfere with the surface to be cleaned.

[0114] The number of the roller brushes 100 can be one, two, three, four or other numbers. The material, size and number of the roller brushes 100 can be set according to specific needs to meet different cleaning needs.

[0116] Among them, when the roller brush 100 is a double-arm roller brush 100, one end of the roller brush 100 is connected to the driving device through a rotating shaft, and the other end of the roller brush 100 is connected to the cabin 3 through another rotating shaft. When the roller brush 100 rotates and interferes with the surface to be cleaned, the hair on the blade 12 may move to either end of the roller brush 100. In view of this, a blocking member 2 can be provided at both ends of the roller brush 100 to prevent the moving hair from being wrapped around the rotating shaft in two directions.

[0117] In one embodiment, the roller brush assembly 200 includes at least one roller brush 100 , one end of the roller brush 100 is connected to a rotating shaft, and the blocking member 2 is disposed at one end of the roller brush 100 close to the driving device.

When the roller brush 100 rotates and interferes with the surface to be cleaned, the hair on the blade 12 may move to either end of the roller brush 100. When the hair on the blade 12 moves away from the rotating shaft, it may be sucked into the air duct or separated from the roller brush 100 during the movement. In view of this, a blocking member 2 can be provided at one end of the roller brush 100 close to the rotating shaft to prevent the moving hair from being entangled on the rotating shaft.

[0119] Among them, when the number of cantilever roller brushes 100 is two or more, at least two roller brushes 100 are arranged relative to each other along their own axes. At least two roller brushes 100 that rotate at differential speeds can pull the hair between the roller brushes 100, so that the hair cannot clump together and can be better sucked into the air duct, thereby improving the cleaning effect. The hair is easily thrown out or even broken under the pulling of the roller brush 100, which greatly reduces the situation where the hair is entangled on the roller brush 100, reduces the situation where the roller brush 100 is deformed due to the hair being entangled on the roller brush 100, reduces the loss of the roller brush 100 drive component, extends the service life of the cleaning equipment, reduces the frequency of manual cleaning of the hair on the roller brush 100, and improves user satisfaction.
