Description

Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a cleaning device. Background Technology

[0002] Currently, electronic cleaning equipment is widely used, such as cleaning devices with vacuuming functions. In these devices, whether upright or push-stick, the cleaning components used to clean the surface can move. Because this movement is rotational, hair can become entangled in the cleaning components, such as roller brushes. In existing technologies, the problem of hair entanglement is solved by scraping, resulting in excessive noise from the cleaning equipment. Utility Model Content

[0003] This application provides a cleaning device to solve the technical problem that excessive noise is caused by interference between the comb teeth and the roller brush during the operation of existing cleaning devices.

[0004] To solve the above-mentioned technical problems, this application provides a cleaning device, which includes a body, a roller brush assembly and a flexible friction element. The body forms a cleaning cavity with an opening. The roller brush assembly is connected to the body and is at least partially disposed in the cleaning cavity. A first end of the flexible friction element is connected to the cavity wall of the cleaning cavity, and a second end of the flexible friction element facing away from the cavity wall is in contact with the cleaning element of the roller brush assembly.

[0005] In one embodiment, the roller brush assembly includes: a roller brush body; a plurality of first cleaning elements spaced apart circumferentially on the outer periphery of the roller brush body; wherein the friction diameter of the end of the flexible friction element away from the cavity wall in the radial direction of the roller brush assembly is smaller than the first cleaning diameter of the first cleaning element in the radial direction.

[0006] In one embodiment, the roller brush assembly further includes: a plurality of second cleaning members, which are spaced apart along the circumferential direction of the roller brush body on the outer periphery of the roller brush body and spaced apart from the first cleaning members; wherein the radial dimension of the second cleaning members is greater than or less than the radial dimension of the first cleaning members, and the second cleaning diameter of the second cleaning members in the radial direction is greater than the friction diameter.

[0007] In one embodiment, the second cleaning member has a smaller radial dimension than the first cleaning member, and the distance between the second cleaning diameter and the friction diameter is 0.5 mm to 1.5 mm.

[0008] In one embodiment, the flexible friction element includes a flexible woven friction element or a soft rubber friction element.

[0009] In one embodiment, the flexible woven friction element includes soft fleece or strips of cloth.

[0010] In one embodiment, the flexible friction element is detachably connected to the cavity wall.

[0011] In one embodiment, a first end of the flexible friction element extends axially along the roller brush assembly, and a second end of the flexible friction element extends radially along the roller brush assembly.

[0012] In one embodiment, the cleaning device further includes: comb teeth, the first end of which is connected to the cavity wall, the comb teeth being located on one side of the flexible friction member in the circumferential direction of the roller brush assembly and spaced apart from the flexible friction member, and the second end of which is away from the cavity wall and is in contact with the cleaning member.

[0013] In one embodiment, in the radial direction of the roller brush assembly, the distance between the end of the second end of the comb teeth and the central axis of the roller brush assembly is greater than the distance between the end of the second end of the flexible friction member and the central axis.

[0014] The beneficial effects of this application are as follows: The cleaning device of this application includes a body, a roller brush assembly, and a flexible friction element. The body forms a cleaning cavity with an opening. The roller brush assembly is connected to the body and is at least partially disposed within the cleaning cavity. The first end of the flexible friction element is connected to the cavity wall of the cleaning cavity, and the second end of the flexible friction element, facing away from the cavity wall, is in contact with the cleaning element of the roller brush assembly. Wherein, the second end of the flexible friction element is in contact with the cleaning element. When the cleaning element rotates, the second end of the flexible friction element rubs against the cleaning element, causing slight deformation of the flexible friction element. This disperses the force acting on the flexible friction element, thereby reducing the high-frequency vibration of the cleaning element caused by contact with the flexible friction element, and thus reducing the noise between the flexible friction element and the cleaning element. Furthermore, when the cleaning element is entangled with foreign objects such as hair, the friction between the flexible friction element and the cleaning element can scrape off the hair entangled on the cleaning element, thereby ensuring the anti-entanglement effect of the flexible friction element.

[0020] Currently, electronic cleaning equipment is widely used, such as cleaning devices with vacuuming functions. In these devices, whether upright or push-stick, the cleaning components used to clean the surface can move. Because this movement is rotational, hair can become entangled in the cleaning components, such as roller brushes. Existing technologies address this hair entanglement problem by scraping, for example, by adding comb teeth to scrape the hair tangled on the roller brush. However, this scraping action during operation results in excessive noise.

[0021] To address the aforementioned technical problems, this application provides a cleaning device, see reference. Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of an embodiment of the cleaning equipment provided in this application. Figure 2 This is a schematic diagram of the structure of an embodiment of the flexible friction element provided in this application. Figure 3 yes Figure 1 The embodiment shows a partially enlarged schematic diagram of the flexible friction element and the roller brush assembly. The cleaning device 10 includes a body 110, a roller brush assembly 120, and a flexible friction element 130. The body 110 forms a cleaning cavity 112 with an opening. The roller brush assembly 120 is connected to the body 110 and is at least partially disposed within the cleaning cavity 112, wherein the roller brush assembly 120 is disposed within the cleaning cavity 112 through the opening. A first end of the flexible friction element 130 is connected to the cavity wall of the cleaning cavity 112, and a second end of the flexible friction element 130 facing away from the cavity wall is in contact with the cleaning element of the roller brush assembly 120.

[0022] In this design, the first end of the flexible friction element 130 is connected to the cavity wall, and the second end of the flexible friction element 130 can interfere with the cleaning element of the roller brush assembly 120 during rotation, thereby enabling the second end of the flexible friction element 130 to scrape away foreign objects such as hair entangled on the cleaning element. The flexible friction element 130 can be a flexible friction element 130 whose entire structure is made of a material with a stiffness lower than that of existing comb teeth, such as a rubber friction element or a flexible woven fabric friction element; or the flexible friction element 130 can be a flexible friction element 130 whose contact part with the cleaning element of the roller brush assembly 120 is made of a material with a stiffness lower than that of existing comb teeth, while the remaining parts can be made of a material with a stiffness greater than or equal to that of existing comb teeth, without limitation.

[0023] The roller brush assembly 120 includes a roller brush body 121 and a cleaning element, wherein the cleaning element is arranged circumferentially around the roller brush body 121 and connected to the roller brush body 121. The number of cleaning elements can be one or more, without limitation. When there are multiple cleaning elements, they are spaced apart circumferentially along the roller brush body 121 or the roller brush assembly 120; when there is only one cleaning element, it can be fitted around the outer periphery of the roller brush body 121, or it can cover part of the outer periphery of the roller brush body 121, without limitation. The roller brush body 121 can rotate around its axis under the drive of the drive assembly of the cleaning device 10, and the rotation of the roller brush body 121 drives the cleaning element to rotate.

[0024] Understandably, the second end of the flexible friction element 130 is arranged in contact with the cleaning element. When the cleaning element rotates, the second end of the flexible friction element 130 rubs against the cleaning element, and the flexible friction element 130 undergoes slight deformation, which disperses the force on the flexible friction element 130. This reduces the high-frequency vibration of the cleaning element caused by contact with the flexible friction element 130, thereby reducing the noise between the flexible friction element 130 and the cleaning element. In addition, when the cleaning element is entangled with foreign objects such as hair, the friction between the flexible friction element 130 and the cleaning element can scrape off the hair entangled on the cleaning element, thereby ensuring the anti-entanglement effect of the flexible friction element 130.

[0025] In one embodiment, the flexible friction element 130 can be a soft rubber friction element, such as a silicone friction element. Alternatively, the flexible friction element 130 can be a flexible woven friction element made of a flexible woven material, such as flexible fleece, cloth strips, or nylon woven fabric. The flexible friction element 130 made of the above materials can reduce the noise generated when the flexible friction element 130 interferes with the cleaning element. Furthermore, the materials are common and inexpensive, which can reduce the development cost of the flexible friction element 130.

[0026] In one embodiment, the roller brush assembly 120 includes a plurality of first cleaning elements 122 and a plurality of second cleaning elements 123. The plurality of first cleaning elements 122 are spaced apart circumferentially around the outer periphery of the roller brush body 121, and the plurality of second cleaning elements 123 are spaced apart circumferentially around the outer periphery of the roller brush body 121 and spaced apart from the first cleaning elements 122. The radial dimension of the first cleaning element 122 on the roller brush body 121 is greater than or less than the radial dimension of the second cleaning element 123 on the roller brush body 121. Therefore, the diameter of the first cleaning surface formed by the first cleaning element 122 on the radial direction of the roller brush body 121 is a first cleaning diameter, and the diameter of the second cleaning surface formed by the second cleaning element 123 on the radial direction of the roller brush body 121 is a second cleaning diameter, wherein the first cleaning diameter is greater than or less than the second cleaning diameter. In this embodiment, in order to enhance the reliability of the flexible friction element 130 in preventing entanglement, the friction diameter formed by the end of the second end of the flexible friction element 130 in the radial direction of the roller brush body 121 is smaller than the first cleaning diameter or the second cleaning diameter.

[0027] When the roller brush body 121 rotates one revolution, the end of the second end of the flexible friction member 130 scrapes against the friction surface formed by the cleaning member on the outer periphery of the roller brush body 121. The diameter of the friction surface is the friction diameter. Understandably, in order to ensure that the flexible friction member 130 can scrape off the foreign matter wrapped around the first cleaning member 122 and the second cleaning member 123, the end of the second end of the flexible friction member 130 needs to rub against the cleaning member with the smallest radial dimension, i.e., the friction diameter is smaller than the smaller of the first and second cleaning diameters. If the radial dimension of the first cleaning member 122 in the roller brush body 121 is larger than that of the second cleaning member 123 in the roller brush body 121, the first cleaning diameter is larger than the second cleaning diameter; in this case, the friction diameter is smaller than the second cleaning diameter. If the radial dimension of the first cleaning member 122 in the roller brush body 121 is smaller than that of the second cleaning member 123 in the roller brush body 121, the first cleaning diameter is smaller than the second cleaning diameter; in this case, the friction diameter is smaller than the first cleaning diameter.

[0028] In one embodiment, the first cleaning member 122 has a larger radial dimension than the second cleaning member 123 in the same direction as the brush body 121. The distance between the second cleaning diameter and the friction diameter is 0.5 mm to 1.5 mm. This distance allows the flexible friction member 130 to simultaneously scrape against both the first and second cleaning members 122 and 123, ensuring the reliability of the flexible friction member 130's anti-entanglement function and guaranteeing the operational reliability of both the second and first cleaning members 122.

[0029] In one embodiment, to facilitate subsequent maintenance such as replacement, upkeep, and cleaning of the flexible friction element 130, the flexible friction element 130 is detachably connected to the cavity wall. Specifically, the flexible friction element 130 can be inserted into the cavity wall, or it can be snapped onto the cavity wall; there are no limitations on this.

[0030] In one embodiment, the flexible friction element 130 is arranged in a "T" shape, with the first end of the flexible friction element 130 being the horizontal part of the "T," which enhances the connection reliability between the flexible friction element 130 and the cavity wall when it is snapped or inserted. The first end of the flexible friction element 130 is the vertical part of the "T," used for scraping the cleaning components of the roller brush assembly 120.

[0031] In one embodiment, in order to enhance the connection stability between the flexible friction element 130 and the cavity wall, the flexible friction element 130 is fixedly connected to the cavity wall. For example, the flexible friction element 130 is pasted to the cavity wall, or the flexible friction element 130 is integrally formed with the cavity wall. This is not limited.

[0032] In one embodiment, the first end of the flexible friction member 130 extends axially along the brush body 121, and the second end of the flexible friction member 130 extends radially along the brush body 121. In other embodiments, the second end of the flexible friction member 130 is perpendicular to the axial direction of the brush body 121 and is disposed intersecting the extending direction of the first cleaning member 122 or the second cleaning member 123.

[0033] In one embodiment, to enhance the reliability of the anti-tangling function of the cleaning device 10, the cleaning device 10 further includes comb teeth 140. The first end of the comb teeth 140 is connected to the cavity wall. The comb teeth 140 are located on any side of the flexible friction member 130 in the circumferential direction of the roller brush assembly 120 and are in contact with the cleaning member. The first end of the comb teeth 140 facing away from the roller brush assembly 120 is connected to the cavity wall and spaced apart from the flexible friction member 130. The second end of the comb teeth 140 facing away from the cavity wall is in contact with the cleaning member. The second end of the comb teeth 140 may extend radially along the roller brush assembly 120; or the second end of the comb teeth 140 may be perpendicular to the axial direction of the roller brush body 121 and intersect with the extension direction of the first cleaning member 122 or the second cleaning member 123, which is not limited here. The extension direction of the second end of the comb teeth 140 may be parallel to or intersect with the extension direction of the second end of the flexible friction member 130, which is not limited here.

[0034] In one embodiment, to enhance the reliability of the cleaning device 10 in preventing tangling, the extension direction of the second end of the comb teeth 140 intersects the extension direction of the second end of the flexible friction member 130.

[0035] In one embodiment, to further enhance the reliability of the cleaning device 10 in preventing tangling, the flexible friction element 130 is provided with comb teeth 140 on both sides of the roller brush assembly 120 in the circumferential direction.

[0036] In one embodiment, in order to reduce the noise generated when the comb teeth 140 interfere with the roller brush assembly 120, the distance between the end of the second end of the comb teeth 140 and the central axis of the roller brush assembly 120 in the radial direction is greater than the distance between the end of the second end of the flexible friction member 130 and the central axis.

[0037] In one embodiment, the second end of the comb teeth 140 that contacts the cleaning component may be covered with a flexible layer or a sound-absorbing layer with sound-absorbing function to reduce the noise generated when the comb teeth 140 rubs against the roller brush assembly 120. The flexible layer may be made of soft rubber, silicone, latex, flexible woven fabric, etc., and is not limited thereto.

[0038] In one embodiment, the body 110 includes a housing 111, which forms a receiving cavity with an opening. The body 110 also has a through groove, which communicates with the receiving cavity and surrounds the cleaning cavity 112. The housing 111 includes a viewing housing 111. Specifically, the housing 111 is a transparent housing 111, allowing the roller brush assembly 120 to be observed from the outside, facilitating real-time monitoring of the roller brush assembly 120 by the user. The housing 111 may be entirely composed of transparent housing 111, or it may be partially composed of transparent housing 111. For example, the housing 111 may include a viewing window formed by the transparent housing 111, located above the roller brush assembly 120, allowing the user to view the roller brush assembly 120 from a top-down perspective.

[0039] In one embodiment, the first cleaning element 122 and the second cleaning element 123 are made of different materials to adapt to different surfaces to be cleaned. The first cleaning element 122 can be a leather strip, and the second cleaning element 123 can be a cloth strip; or the first cleaning element 122 can be a cloth strip, and the second cleaning element 123 can be a leather strip, which is not limited here. Wherein, when the first cleaning element 122 or the second cleaning element is a cloth strip, and the flexible friction element 130 is a flexible woven friction element, the stiffness of the flexible friction element 130 is greater than the stiffness of the cloth strip. For example, the flexible woven friction element is a high-density velvet cloth, and the cleaning element is a low-density velvet cloth, etc.
