Description

Technical Field

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

[0002] As people's living standards improve, more and more families are keeping pets. While pets bring companionship and joy, they also bring some cleaning problems, among which pet hair residue on bed sheets is a major concern for many pet owners. Currently, the pet cleaning market is expanding rapidly, and various cleaning devices are emerging one after another. However, existing devices have revealed many shortcomings when dealing with pet hair on bed sheets.

[0003] For example, vacuum cleaners are common cleaning devices that perform reasonably well when cleaning large areas of dust and debris, but they struggle to handle pet hair on bed sheets. Many vacuum cleaners have limited cleaning power and cannot completely remove hair tightly entangled in the sheet fibers. Especially for fine and soft hair, even increasing the suction power is futile, and a considerable amount of hair will still stubbornly remain on the sheets. Utility Model Content

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0078] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0082] Combination Figures 4 to 8 As shown, a roller brush 100 according to some embodiments of this application includes a roller member 1, at least one comb body portion 21, at least one protrusion portion 22, and at least one electrostatic adsorption member 3, wherein the comb body portion 21, the protrusion portion 22, and the electrostatic adsorption member 3 are all disposed on the roller member 1. Combined with Figures 1 to 3 As shown, the roller brush 100 can be applied to the cleaning equipment 200. The roller component 1 is adapted to be connected to the drive mechanism of the cleaning equipment 200 for transmission. Under the driving action of the drive mechanism, the roller component 1 rotates around its own central axis, thereby achieving the effect that the drive mechanism of the cleaning equipment 200 drives the roller brush 100 mounted on the cleaning equipment 200 to rotate. That is, during the rotation of the roller brush 100, the roller brush 100 rotates around its own central axis.

[0083] See Figures 4 to 8 As shown, the comb body 21 includes a plurality of comb teeth 211, which are arranged sequentially along the axial direction of the roller member 1. That is, the comb body 21 extends along the axial direction of the roller member 1, and adjacent comb teeth 211 are spaced apart in the extending direction of the comb body 21. The protrusion 22 is constructed as an elongated strip, and extends along the axial direction of the roller member 1. Adjacent comb bodies 21 and protrusions 22 are spaced apart in the circumferential direction of the brush 100.

[0084] For example, in combination Figures 4 to 8As shown, in one embodiment of this application, the roller brush 100 is provided with six comb sections 21 and six protrusions 22. Every three comb sections 21 and every three protrusions 22 are divided into a group of combined structures, and the six comb sections 21 and six protrusions 22 are divided into two groups of combined structures. Along the axial direction of the roller 1, the two groups of combined structures are respectively arranged on both sides of the roller 1, and an electrostatic adsorption member 3 is provided between the two groups of combined structures. In each group of combined structures, a protrusion 22 is provided between two adjacent comb sections 21, or it can be understood that a comb section 21 is provided between two adjacent protrusions 22.

[0085] Combination Figures 1 to 8 As shown, during the cleaning process of the cleaning device 200, the roller brush 100 is in a rotating state, and the protrusions 22 continuously "beat" the bed sheet, causing objects (such as dust, hair, fleas, etc.) attached to the bed sheet to separate from it. Because the roller brush 100 is continuously rotating, the elongated, sheet-like protrusions 22 act as "fan blades," blowing the detached objects towards the suction inlet of the upstream channel section 2013a of the cleaning device 200. Simultaneously, the negative pressure channel 2013 of the cleaning device 200 is in a negative pressure state, attracting objects to the negative pressure channel 2013 and transporting them to the dirt chamber 2020 of the cleaning device 200.

[0086] It is important to understand that, see Figures 1 to 3As shown, in some embodiments of this application, a negative pressure channel 2013 is provided within the housing 201 of the cleaning device 200. The cleaning device 200 also includes a negative pressure generator 203, which drives airflow along the negative pressure channel 2013 to transport the adsorbed material to the waste chamber 2020. The negative pressure channel 2013 includes an upstream channel section 2013a and a downstream channel section 2013b. The upstream channel section 2013a connects the roller brush chamber 20120 and the waste chamber 2020, while the downstream channel section 2013b connects the waste chamber 2020 and the negative pressure generator 203. Thus, when the negative pressure generator 203 is in operation, the driving gas first flows into the brush chamber 20120 from the outside, and then sequentially flows along the upstream channel section 2013a, the waste chamber 2020, and the downstream channel section 2013b. When the particulate matter flowing with the airflow passes through the waste chamber 2020, the waste storage member 202 can intercept the particulate matter in the waste chamber 2020, and only allow gas to flow from the waste chamber 2020 into the downstream channel section 2013b. Furthermore, along the extension direction of the upstream channel section 2013a, the suction port of the upstream channel section 2013a is positioned opposite to the electrostatic adsorption member 3 in the direction of fluid flow, thus more effectively utilizing the negative pressure airflow to absorb the material gathered on the electrostatic adsorption member 3, thereby improving the cleaning ability of the cleaning equipment 200.

[0087] Since the comb body 21 includes multiple comb teeth 211, and adjacent comb teeth 211 are spaced apart, when the roller brush 100 is rotating and comes into contact with soft, fine materials such as hair, the comb body 21 wraps around the soft, fine materials such as hair, causing them to adhere to the roller brush 100. Furthermore, since the comb body 21 and protrusions 22 are spaced apart along the circumference of the roller brush 100, the protrusions 22 provide support for the soft, fine materials such as hair adhering to the roller brush 100 in the radial direction of the roller brush 100, thereby preventing the soft, fine materials such as hair from sticking to the root of the comb body 21. Thus, when cleaning the soft, fine materials such as hair wrapped around the roller brush 100, the user can easily remove the soft, fine materials such as hair from the roller brush 100 by inserting their fingers into the space formed between the comb body 21 and the protrusions 22. Alternatively, users can use tools such as scissors to cut soft, fine materials such as hair through the space formed between the comb body 21 and the protrusion 22, thus easily cleaning away soft, fine materials such as hair entangled in the roller brush 100. It is also worth noting that as the roller brush 100 rotates, the comb body 21 extends deep into the bed sheet, effectively scraping away soft, fine materials such as hair attached to the bed sheet.

[0088] The electrostatic adsorption element 3 is disposed on the roller element 1. Therefore, when the roller brush 100 is rotating, the electrostatic adsorption element 3 continuously moves in a circular motion. The moving electrostatic adsorption element 3 rubs against the hair attached to the bed sheet to generate static electricity, so that the roller brush 100 generates electrostatic attraction to the hair, further prompting the roller brush 100 to clean the hair attached to the bed sheet. Exemplarily, in one embodiment of this application, see [reference needed]. Figure 2 As shown, the electrostatic adsorption component 3 is located in front of the suction port of the upstream channel section 2013a. After the electrostatic adsorption component 3 adsorbs the hair, the negative pressure channel 2013 under negative pressure will suck up the hair attached to the electrostatic adsorption component 3, thereby sucking the hair into the negative pressure channel 2013 and then conveying the hair to the dirt chamber 2020 of the cleaning device 200 through the negative pressure channel 2013.

[0089] Therefore, the roller brush 100 according to this application is provided with a comb body 21, a protrusion 22 and an electrostatic adsorption member 3, so that the cleaning device 200 equipped with the roller brush 100 of this application can effectively clean the bed sheet, improve the cleaning ability of the cleaning device 200, and thus improve the user experience.

[0090] See Figure 4 As shown, in some embodiments of this application, the radial dimension of the end of the comb body 21 away from the roller member 1 is D1, the radial dimension of the end of the protrusion 22 away from the roller member 1 is D2, and the radial dimension of the end of the electrostatic adsorption member 3 away from the roller member 1 is D3, satisfying the relationship: D3 < D1 < D2.

[0091] For example, in one embodiment of this application, D2 = 33 mm, D1 = 31 mm, and D3 = 29 mm. Since D2 > D1 > D3, during the rotation of the roller brush 100, the part of the roller brush 100 that first contacts the bed sheet is the protrusion 22, thereby "beating" the bed sheet through the protrusion 22 to promote the separation of objects attached to the bed sheet (such as dust, hair, fleas, etc.) from the bed sheet. Along the radial direction of the roller brush 100, the end of the protrusion 22 away from the roller 1 can deform. This reduces the resistance to the rotation of the roller brush 100 while ensuring that the protrusion 22 effectively beats the bed sheet, so that the roller brush 100 has a higher rotation speed. During the rotation of the roller brush 100, the protrusion 22 generates a large blowing force, which is beneficial for the protrusion 22 to blow the objects detached from the bed sheet toward the negative pressure channel 2013 of the cleaning device 200. Furthermore, since the end of the protrusion 22 away from the roller 1 can deform, the radial dimension of the protrusion 22 in the deformed state is smaller than the radial dimension of the comb body 21, so that the comb body 21 can extend into the deep layer of the bed sheet, thereby enabling the comb body 21 to effectively scrape away soft and fine materials such as hair attached to the bed sheet.

[0092] In addition, along the radial direction of the roller brush 100, the end of the comb body 21 away from the roller member 1 can deform. This not only avoids hard contact between the comb body 21 and the deep area of ​​the bed sheet, thereby reducing the resistance during the rotation of the roller brush 100, but also reduces the distance between the electrostatic adsorption member 3 and the hair attached to it. This is conducive to the generation of static electricity between the electrostatic adsorption member 3 and the hair, so that the electrostatic adsorption member 3 can adsorb the hair.

[0093] Therefore, according to the roller brush 100 of this application, since D2 > D1 > D3, the protrusion 22 contacts the bed sheet first, followed by the comb body 21, and then the electrostatic adsorption member 3. This facilitates the effective and thorough cleaning of the bed sheet by the roller brush 100, so that the cleaning device 200 equipped with the roller brush 100 of this application has a high cleaning ability, thereby improving the user experience.

[0094] In some of the above embodiments, the relationship D2 > D1 > D3 is used as an example for illustration, but this application is not limited thereto. For example, in other embodiments of this application, the relationship D1 > D2 > D3 is satisfied. For example, in one embodiment of this application, D1 = 35 mm, D2 = 33 mm, and D3 = 29 mm. Since D1 > D2 > D3, during the rotation of the roller brush 100, the part of the roller brush 100 that first contacts the bed sheet is the comb body 21. During the contact with the bed sheet, the comb body 21 can not only "beat" the bed sheet to promote the separation of objects (such as dust, hair, fleas, etc.) attached to the bed sheet from the bed sheet, but also better "grab" fine filamentous objects such as hair on the bed sheet.

[0095] It should also be noted that in some embodiments of this application, the dimensional relationship between the comb body 21, the protrusion 22, and the electrostatic adsorption member 3 satisfies the following formula: D3 < D1 < D2, and also satisfies the following formula: 8 mm ≤ D2 - D3 ≤ 12 mm. That is, in the radial direction of the roller brush 100, the distance between the radial dimension of the end of the protrusion 22 away from the roller 1 and the radial dimension of the end of the electrostatic adsorption member 3 away from the roller 1 is controlled within the range of 8 mm to 12 mm. Of course, it can also be understood that the distance between the radial dimension of the end of the electrostatic adsorption member 3 away from the roller 1 and the outer contour of the roller brush 100 in the radial direction is controlled within the range of 8 mm to 12 mm. This ensures that the electrostatic adsorption member 3 remains in contact with the surface to be cleaned (e.g., a bed sheet), thereby facilitating effective electrostatic adsorption by the electrostatic adsorption member 3. For example, the difference between D2 and D3 can be 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, 10.5 mm, 11 mm, 11.5 mm, 12 mm, or 12.5 mm.

[0096] Alternatively, in some embodiments of this application, the dimensional relationship between the comb body 21, the protrusion 22, and the electrostatic adsorption member 3 satisfies the following formula: D3 < D2 < D1, and also satisfies the following formula: 8 mm ≤ D1 - D3 ≤ 12 mm. That is, in the radial direction of the roller brush 100, the distance between the radial dimension of the end of the comb body 21 away from the roller member 1 and the radial dimension of the end of the electrostatic adsorption member 3 away from the roller member 1 is controlled within the range of 8 mm to 12 mm. Of course, it can also be understood that the distance between the radial dimension of the end of the electrostatic adsorption member 3 away from the roller member 1 and the outer contour of the roller brush 100 in the radial direction is controlled within the range of 8 mm to 12 mm. This ensures that the electrostatic adsorption member 3 remains in contact with the surface to be cleaned (e.g., a bed sheet), thereby facilitating effective electrostatic adsorption by the electrostatic adsorption member 3. For example, the difference between D2 and D3 can be 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, 10.5 mm, 11 mm, 11.5 mm, 12 mm, or 12.5 mm.

[0097] Furthermore, it should be noted that the radial dimension (D3) of the end of the electrostatic adsorption component 3 furthest from the roller component 1 is greater than or equal to the maximum outer contour of the roller component 1 in the radial direction. That is, in the radial direction of the roller brush 100, the outer peripheral surface of the electrostatic adsorption component 3 is flush with the outermost outer peripheral surface of the roller component 1, or the outer peripheral surface of the electrostatic adsorption component 3 protrudes beyond the outermost outer peripheral surface of the roller component 1. This avoids the situation where the roller component 1 prevents the electrostatic adsorption component 3 from maintaining contact with the surface to be cleaned (e.g., a bed sheet), thus facilitating effective electrostatic adsorption by the electrostatic adsorption component 3.

[0098] For example, see Figure 5 As shown in the figure, in one embodiment of this application, the electrostatic adsorption member 3 is disposed in the mounting space 132a defined by the two first limiting edges 132d in the roller member 1. See also... Figure 6 As shown, when the electrostatic adsorption component 3 is assembled on the roller component 1, the radial dimension of the end of the electrostatic adsorption component 3 furthest from the roller component 1 in the radial direction is D3, and the radial dimension of the first limiting stop 132d furthest from the end of the roller component 1 is D4, satisfying the relationship: D3 ≥ D4. This can also be understood as: when D3 = D4, the outer circumferential surface of the electrostatic adsorption component 3 is flush with the outer circumferential surface of the first limiting stop 132d in the radial direction; when D3 > D4, the outer circumferential surface of the electrostatic adsorption component 3 protrudes beyond the outer circumferential surface of the first limiting stop 132d in the radial direction. Thus, in the radial direction of the roller brush 100, since the radial dimension of the end of the electrostatic adsorption component 3 furthest from the roller component 1 is greater than or equal to the radial dimension of the end of the first limiting stop 132d furthest from the roller component 1, the electrostatic adsorption component 3 remains in contact with the surface to be cleaned (e.g., a bed sheet), thereby facilitating effective electrostatic adsorption by the electrostatic adsorption component 3.

[0099] In some embodiments of this application, the comb body 21, the protrusion 22, and the electrostatic adsorption member 3 can all be made of relatively soft materials, such as nylon 6 (also known as polyamide 6) or nylon-66 (also known as polyadiohexylenediamine).

[0100] The specific structures of the protrusions 22 and the electrostatic adsorption element 3 can be soft bristles, fabric, felt, fine hair, or pile. The softness can be determined based on the pliability of the bristles or pile used. The shape and size of the bristles and / or pile can be selected based on the desired application. In one embodiment, the density of the bristles and / or pile in the electrostatic adsorption element 3 is greater than the density of the bristles and / or pile in the protrusions 22, and the density of the bristles and / or pile in the protrusions 22 is greater than the density of the comb teeth 211 in the comb body 21. Furthermore, the diameter of the bristles and / or pile in the electrostatic adsorption element 3 is smaller than the density of the bristles and / or pile in the protrusions 22, and the diameter of the bristles and / or pile in the electrostatic adsorption element 3 is smaller than the diameter of the comb teeth 211.

[0101] More specifically, for example, in some embodiments, the length of the bristles or down in the electrostatic adsorption element 3 may be between 0.5 mm and 10 mm (e.g., 2 mm to 5 mm), and the diameter may be between 0.01 mm and 0.04 mm (e.g., 0.01 mm to 0.03 mm). According to some embodiments, the bristles and / or down may have a length of 3 mm and a diameter of 0.02 mm. The bristles and / or down may have any shape. For example, the bristles and / or down may be straight, curved, and / or may have a composite shape.

[0102] According to one embodiment, the bristles and / or down may have a generally U-shaped and / or Y-shaped shape. The U-shaped and / or Y-shaped bristles and / or down increase the number of contact points with the surface to be cleaned (e.g., a bed sheet), thus enhancing the friction between the electrostatic adsorption element 3 and the surface to be cleaned, thereby generating static electricity. Of course, the bristles and / or down can also be made of other materials.

[0103] It should be further noted that, in one of the above embodiments, the density of the bristles and / or down in the electrostatic adsorption member 3 is greater than the density of the bristles and / or down in the protrusion 22, and the density of the bristles and / or down in the protrusion 22 is greater than the density of the comb teeth 211 in the comb body 21. Furthermore, the diameter of the bristles and / or down in the electrostatic adsorption member 3 is smaller than the density of the bristles and / or down in the protrusion 22, and the diameter of the bristles and / or down in the electrostatic adsorption member 3 is smaller than the diameter of the comb teeth 211. This design facilitates the concentration of static electricity in the electrostatic adsorption member 3.

[0104] See Figure 5 and Figure 6 As shown, in some embodiments of this application, the roller brush 100 includes a cleaning member 2, which includes a sleeve portion 23, at least one comb portion 21, and at least one protrusion 22. The outer peripheral surface of the sleeve portion 23 is provided with both the comb portion 21 and the protrusion 22, and the sleeve portion 23 is adapted to fit the roller member 1.

[0105] For example, see Figure 5 and Figure 6 As shown, in some embodiments of this application, the roller brush 100 is provided with two cleaning components 2, each of which includes a sleeve portion 23, three comb portions 21, and three protrusions 22. The three comb portions 21 and three protrusions 22 are all fixedly disposed on the outer peripheral surface of the sleeve portion 23. Since the sleeve portion 23 is a hollow cylindrical structure and is suitable for fitting onto the roller component 1, the cleaning component 2 can be fitted and assembled onto the roller component 1. By providing the sleeve portion 23, and with both the comb portions 21 and the protrusions 22 disposed on the sleeve portion 23, when the comb portions 21 and / or the protrusions 22 are damaged, replacing the cleaning component 2 will achieve the effect of replacing the damaged comb portions 21 and / or the protrusions 22.

[0106] Additionally, it should be noted that the cleaning component 2 can be a one-piece molded part or a two-piece molded part. For example, in some embodiments of this application, the comb body 21 and the protrusion 22 need to meet the requirement of deformability. Therefore, in the process of manufacturing the cleaning component 2, the sleeve part 23 can be molded in one piece using a material with high plasticity, and then the comb body 21 and the protrusion 22 can be molded in a second time on the outer peripheral surface of the sleeve part 23 using a material with deformability (such as elastic plastic, for example, polyester material).

[0107] In some other embodiments of this application, the comb body 21 and the protrusion 22 can be directly formed on the outer peripheral surface of the roller 1. It can also be understood that the root of the comb body 21 and the root of the protrusion 22 are directly connected to the outer peripheral surface of the roller 1. For example, the comb body 21 and the protrusion 22 can be formed on the outer surface of the manufactured roller 1 using an injection molding process.

[0108] See Figure 7 and Figure 9 As shown, in some embodiments of this application, the roller component 1 includes a first connecting member 11, a second connecting member 12, and a shaft body component 13. The first connecting member 11 and the second connecting member 12 are respectively assembled at both ends of the shaft body component 13. The first connecting member 11 and the second connecting member 12 are configured to be connected to the drive mechanism of the cleaning device 200 for transmission, so that under the driving action of the drive mechanism of the cleaning device 200, the roller component 1 rotates around its own central axis, thereby achieving the effect that the drive mechanism of the cleaning device 200 drives the roller brush 100 assembled on the cleaning device 200 to rotate.

[0109] For example, in one embodiment, the drive mechanism of the cleaning device 200 includes two drive shafts, both of which are driveably connected to the first connector 11 and the second connector 12, so that the two drive shafts jointly drive the roller brush 100 to rotate. Alternatively, the drive mechanism of the cleaning device 200 includes a drive shaft and a driven shaft, wherein the drive shaft is driveably connected to one of the first connector 11 and the second connector 12, and the driven shaft is driveably connected to the other of the first connector 11 and the second connector 12. The drive shaft and the driven shaft are used to jointly connect the roller 1, so that the roller 1 rotates about its own central axis during the rotation driven by the drive shaft.

[0110] See Figure 5 and Figure 7 As shown, in some embodiments of this application, the shaft body 13 includes at least two first shafts 131 and at least one second shaft 132, with each second shaft 132 disposed between every two first shafts 131. The comb portion 21 and the protrusion 22 are both disposed on the first shafts 131. For example, see [reference needed]. Figure 7 and Figure 9 As shown, in some embodiments of this application, a shaft body 13 includes two first shafts 131 and a second shaft 132, with the two first shafts 131 respectively connected to the two ends of the second shaft 132 to form the shaft body 13.

[0111] Additionally, please combine Figure 4 and Figure 5 As shown, the second shaft 132 is provided with an installation space 132a, and the electrostatic adsorption component 3 is assembled in the installation space 132a, thereby achieving the effect of assembling the electrostatic adsorption component 3 onto the shaft body 13, that is, achieving the effect of assembling the electrostatic adsorption component 3 onto the roller component 1. Additionally, two cleaning components 2 are respectively sleeved on the two first shafts 131, thereby positioning the electrostatic adsorption component 3 between two sets of combined structures (each set of combined structures includes at least one comb body portion 21 and at least one protrusion portion 22).

[0112] For example, in some embodiments of this application, the first connector 11 is integrally formed with the connected first shaft 131 and / or the second connector 12 is integrally formed with the connected first shaft 131. For instance, in one embodiment of this application, the first connector 11 is integrally formed with the connected first shaft 131, and the second connector 12 is integrally formed with the connected first shaft 131. This improves the connection reliability between the first connector 11 and the connected first shaft 131, and also improves the connection reliability between the second connector 12 and the connected first shaft 131. It should be understood that the first connector 11 and the second connector 12 are used for transmission connection to the drive mechanism of the cleaning device 200, thereby achieving the effect of the roller brush 100 rotating. With the improved connection reliability between the first connector 11 and the connected first shaft 131, and with the improved connection reliability between the second connector 12 and the connected first shaft 131, the roller brush 100 has higher reliability during long-term use, which is beneficial for extending the service life of the roller brush 100.

[0113] See Figure 9 As shown, in some embodiments of this application, the peripheral wall of the first shaft 131 is provided with a fixing groove 1310, and part of the structure of the sleeve portion 23 of the cleaning component 2 is adapted to extend into the fixing groove 1310, so as to improve the assembly stability of the cleaning component 2 and the first shaft 131 and reduce the risk of the cleaning component 2 moving relative to the first shaft 131 (e.g., rotating, moving).

[0114] It should be further noted that in the above embodiments, the first shaft 131 and the cleaning component 2 are two independent parts, which are assembled into one unit through a subsequent assembly process. However, this application is not limited to this. For example, in some other embodiments of this application, the cleaning component 2 can be formed on the pre-made first shaft 131 by injection molding. During the injection molding process, the flowing plastic material is better injected into the fixing groove 1310, so that the cleaning component 2 and the first shaft 131 have a stronger adhesive force, and the connection between the cleaning component 2 and the first shaft 131 is more reliable.

[0115] Combination Figure 5 As shown, the flange 132b of the second shaft 132 is provided with at least one receiving notch 132c, which is used to receive the protrusion 22 so that at least a portion of the protrusion 22 near the second shaft 132 is located in the receiving notch 132c in the axial direction of the brush 100.

[0116] For example, see Figure 5As shown in some embodiments of this application, each cleaning component 2 is provided with three protrusions 22, and the flange 132b of the second shaft 132 can be provided with three receiving notches 132c. When the cleaning component 2 is assembled to the first shaft 131, the three protrusions 22 correspond one-to-one with the three receiving notches 132c. In the radial direction of the roller brush 100, the sleeve portion 23 is located inside the flange 132b. By providing receiving notches 132c for receiving the protrusions 22 in the flange 132b, a portion of the structure of the protrusions 22 overlaps with the flange 132b along the circumference of the roller brush 100. With this design, soft and fine materials such as hair are prevented from getting caught in the inner side of the flange 132b during the rotation of the roller brush 100. For example, soft and fine materials such as hair are prevented from getting caught in the gap between the flange 132b and the sleeve portion 23, so that soft and fine materials such as hair can be wrapped around the outer side of the flange 132b and / or the upper end of the protrusion 22, so that the user can clean up soft and fine materials such as hair.

[0117] Furthermore, since the flange 132b is provided with a receiving notch 132c for accommodating the protrusion 22, a portion of the protrusion 22 overlaps with the second shaft 132 in the axial direction of the roller brush 100. This can also be understood as a portion of the protrusion 22 being embedded within the second shaft 132 in the axial direction of the roller brush 100. This facilitates the gathering of soft, fine materials such as hair towards the second shaft 132 during the rotation of the roller brush 100 to clean the surface. It should be understood that... (Refer to...) Figure 2 As shown, in some embodiments of this application, when the roller brush 100 is applied to the cleaning device 200, the second shaft 132 is positioned opposite to the upstream channel segment 2013a of the negative pressure channel 2013. Since the roller brush 100 according to this application is advantageous in gathering soft and slender materials such as hair at the second shaft 132, this is beneficial for the negative pressure channel 2013 to absorb soft and slender materials such as hair, thereby improving the cleaning ability of the cleaning device 200.

[0118] Combination Figure 4 As shown, in some embodiments of this application, the width of the receiving notch 132c along the circumferential direction of the second shaft 132 (i.e., the circumferential direction of the roller brush 100) is greater than the thickness of the protrusion 22. This design allows the protrusion 22 to have a certain swing angle during the rotation of the roller brush 100, which helps to change the radial dimension of the protrusion 22 and avoids wear caused by excessive swinging of the protrusion 22. In other words, the receiving notch 132c can effectively control the swing amplitude of the protrusion 22, improving the durability of the protrusion 22.

[0119] See Figure 5 , Figure 7 and Figure 11As shown, in some embodiments of this application, the outer peripheral surface of the second shaft 132 is provided with two first limiting flanges 132d, which are spaced apart along the axial direction of the second shaft 132 to form an installation space 132a. When the electrostatic adsorption component 3 is assembled in the installation space 132a, the two first limiting flanges 132d can abut and limit the two sides of the electrostatic adsorption component 3 along the axial direction of the roller component 1. Since the roller brush 100 needs to rotate at high speed during the operation of the cleaning equipment 200, the two first limiting flanges 132d together restrict the installation space 132a, which has a groove structure. When the electrostatic adsorption component 3 is assembled in the installation space 132a, the first limiting flanges 132d effectively limit the electrostatic adsorption component 3 to prevent the electrostatic adsorption component 3 from moving along the axial direction of the roller component 1, thus ensuring the assembly stability of the electrostatic adsorption component 3.

[0120] See Figure 4 , Figure 5 , Figure 7 and Figure 11 As shown, in some embodiments of this application, the second shaft 132 is further provided with a guide 132e, which connects the flange 132b and the first limiting stop 132d, and is located between two adjacent receiving notches 132c along the circumference of the second shaft 132. It should be further noted that, referring to... Figure 4 As shown, the notch 132c is used to accommodate the protrusion 22, thus creating a wavy space above the flange 132b. This reduces the adhesion of soft, slender materials such as hair, preventing them from wrapping around the second shaft 132. Under the negative pressure of the negative pressure channel 2013, the soft, slender materials enter the dirt chamber 2020 of the cleaning device 200. It is worth noting that in one embodiment of this application, taking the guide 132e as a triangular plate, the inclined side of the guide 132e guides the soft, slender materials such as hair, causing them to slide radially inwards towards the second shaft 132, which helps reduce the adhesion of the soft, slender materials.

[0121] Combination Figures 9 to 12 As shown, in some embodiments of this application, the second shaft 132 includes an assembly wheel 1321 and an annular mounting body 1322, with the annular mounting body 1322 sleeved on the assembly wheel 1321. Along the axial direction of the assembly wheel 1321, both ends of the assembly wheel 1321 are connected to the first shaft 131, and the annular mounting body 1322 is provided with an installation space 132a and a receiving notch 132c.

[0122] For example, in some embodiments of this application, see [reference]. Figure 9As shown, the assembly wheel body 1321 and the two first shaft bodies 131 are integrally formed parts, meaning the two first shaft bodies 131 are permanently fixedly connected to both ends of the assembly wheel body 1321. Figure 9 and Figure 10 As shown, the annular mounting body 1322 includes a first mounting body 13221 and a second mounting body 13222. The main structure of the first mounting body 13221 and the second mounting body 13222 is arc-shaped. The first mounting body 13221 and the second mounting body 13222 are both fixedly assembled to the assembly wheel body 1321, so that the first mounting body 13221 and the second mounting body 13222 are combined to form an annular mounting body 1322, which is sleeved on the assembly wheel body 1321.

[0123] For example, when the roller brush 100 rotates to clean hair on the bed sheet, the hair can move through the protrusion 22 to the annular mounting body 1322, be transferred by the guide 132e, and then be attracted by the electrostatic adsorption member 3.

[0124] See Figure 11 As shown, the outer peripheral surface of the annular mounting body 1322 is provided with two first limiting flanges 132d with annular structure. Along the axial direction of the annular mounting body 1322, the two annular mounting bodies 1322 are spaced apart to form an installation space 132a. The installation space 132a is used to assemble the electrostatic adsorption component 3, that is, the electrostatic adsorption component 3 is suitable for assembly on the annular mounting body 1322, thereby realizing the effect of assembling the annular mounting body 1322 on the roller component 1.

[0125] In addition, combined Figures 9 to 12 As shown, the assembly wheel body 1321 is provided with a screw hole 13210, and the annular mounting body 1322 is provided with a corresponding countersunk hole 13220, which is located within the mounting space 132a. The second shaft body 132 also includes a screw 13223, which is adapted to pass through the countersunk hole 13220 to be screwed into the screw hole 13210. Thus, the annular mounting body 1322 is fixedly assembled to the assembly wheel body 1321 by the screw 13223. It is worth noting that by setting the position of the screw hole 13210 within the mounting space 132a, when the electrostatic adsorption component 3 is assembled within the mounting space 132a, the electrostatic adsorption component 3 covers the screw 13223, which not only improves the aesthetics but also avoids the accumulation of dust and debris at the countersunk hole 13220.

[0126] See Figure 11As shown, in some embodiments of this application, along the axial direction of the annular mounting body 1322, both sides of the annular mounting body 1322 are provided with a flange 132b with a circular structure. The axial direction of the flange 132b extends along the axial direction of the annular mounting body 1322, and three sequentially arranged receiving notches 132c are also provided in the circumferential direction of each flange 132b. The receiving notches 132c are used to receive the protrusion 22.

[0127] See Figure 12 As shown, in some embodiments of this application, the first mounting body 13221 is provided with one of the positioning groove 151 and the positioning protrusion 152, and the second mounting body 13222 is provided with the other of the positioning groove 151 and the positioning protrusion 152.

[0128] For example, see Figure 12 As shown, along the extension direction of the first mounting body 13221, which is constructed in an arc shape, positioning protrusions 152 are provided at both ends of the first mounting body 13221. Additionally, along the extension direction of the second mounting body 13222, which is also constructed in an arc shape, positioning grooves 151 are provided at both ends of the second mounting body 13222. When the first mounting body 13221 and the second mounting body 13222 are assembled to form an annular mounting body 1322, the positioning protrusions 152 are adapted to extend into the positioning grooves 151. The positioning protrusions 152 and the positioning grooves 151 achieve the positioning and assembly effect of the first mounting body 13221 and the second mounting body 13222, thereby improving the assembly accuracy of the first mounting body 13221 and the second mounting body 13222.

[0129] For example, both the first mounting body 13221 and the second mounting body 13222 are fixedly assembled to the assembly wheel body 1321 by bolts. During the assembly of the annular mounting body 1322 to the assembly wheel body 1321, the operator can first assemble and fix the first mounting body 13221 to the assembly wheel body 1321. Then, during the assembly of the second mounting body 13222 to the assembly wheel body 1321 and its engagement with the first mounting body 13221, the positioning protrusion 152 and the positioning groove 151 provide a positioning fit, thereby limiting the relative positional relationship between the first mounting body 13221 and the second mounting body 13222. This allows for quick positioning of the mounting holes in the second mounting body 13222 and the assembly wheel body 1321, facilitating the bolt assembly and fixing of the second mounting body 13222 to the assembly wheel body 1321.

[0130] In addition, combined Figures 9 to 12As shown, the first mounting body 13221 and the second mounting body 13222 are fixedly connected to the assembly wheel body 1321 by screw connection, which not only simplifies the structural design of the assembly wheel body 1321 and the annular mounting body 1322 (i.e., the first mounting body 13221 and the second mounting body 13222), but also facilitates the molding of the first mounting body 13221 and the second mounting body 13222.

[0131] Combination Figures 10 to 12 As shown, in some embodiments of this application, the inner wall of the first mounting body 13221 and / or the inner wall of the second mounting body 13222 is provided with one of the axial limiting groove 141 and the axial limiting protrusion 142, and the assembly wheel body 1321 is provided with the other of the axial limiting groove 141 and the axial limiting protrusion 142. The axial limiting protrusion 142 is adapted to be assembled in the axial limiting groove 141.

[0132] For example, see Figures 10 to 12 As shown, in one embodiment of this application, both the inner wall of the first mounting body 13221 and the inner wall of the second mounting body 13222 are provided with axial limiting grooves 141. The axial limiting grooves 141 of the first mounting body 13221 extend in the extending direction, and the axial limiting grooves 141 of the second mounting body 13222 also extend in the extending direction. Additionally, the outer circumferential surface of the assembly wheel 1321 is provided with an annular axial limiting protrusion 142, which extends circumferentially along the assembly wheel 1321.

[0133] When the first mounting body 13221 is assembled onto the assembly wheel body 1321, the axial limiting protrusion 142 provided on the assembly wheel body 1321 is adapted to extend into the axial limiting groove 141 provided on the first mounting body 13221, and in the axial direction of the assembly wheel body 1321, the groove wall of the axial limiting groove 141 is adapted to abut against and limit the axial limiting protrusion 142, thereby achieving the effect of axial upper limit engagement between the first mounting body 13221 and the assembly wheel body 1321 on the second shaft body 132. Similarly, by providing the axial limiting groove 141 on the second mounting body 13222, the second mounting body 13222 and the assembly wheel body 1321 achieve the effect of axial upper limit engagement between the second mounting body 13222 and the assembly wheel body 1321 on the second shaft body 132 when the second mounting body 13222 is assembled onto the assembly wheel body 1321. Since both the first mounting body 13221 and the second mounting body 13222 are provided with axial limiting grooves 141, the assembly stability of the assembly wheel body 1321 and the annular mounting body 1322 is further improved.

[0134] Combination Figures 9 to 12As shown, in some embodiments of this application, the inner walls of the first mounting body 13221 and the second mounting body 13222 are provided with a second limiting stop 1411 and a third limiting stop 1412. Along the axial direction of the annular mounting body 1322, the second limiting stop 1411 and the third limiting stop 1412 form an axial limiting groove 141 at intervals. It can also be understood that the second limiting stop 1411 and the third limiting stop 1412 are respectively constructed as the two side walls of the axial limiting groove 141.

[0135] Additionally, the second limiting stop 1411 and / or the third limiting stop 1412 are provided with circumferential limiting protrusions 161, and the mounting wheel body 1321 is provided with circumferential limiting grooves 162. The circumferential limiting protrusions 161 are adapted to be fitted into the circumferential limiting grooves 162. For example, see [reference needed]. Figure 5 and Figure 7 As shown, in one embodiment of this application, the second limiting stop 1411 is provided with a circumferential limiting protrusion 161. The circumferential limiting protrusion 161 extends radially along the annular mounting body 1322. In this way, when the annular mounting body 1322 and the mounting wheel body 1321 are assembled and engaged, since the circumferential limiting protrusion 161 is located in the circumferential limiting groove 162, the circumferential limiting protrusion 161 and the circumferential limiting groove 162 abut and limit the engagement, thereby achieving the effect of circumferential limiting engagement between the annular mounting body 1322 and the mounting wheel body 1321 on the second shaft body 132.

[0136] Combination Figures 9 to 12 As shown, in some embodiments of this application, along the circumference of the annular mounting body 1322, correspondingly provided second limiting flanges 1411 form clamping spaces 172 at intervals, and along the axial direction of the annular mounting body 1322, third limiting flanges 1412 are provided outside the second limiting flanges 1411. The assembly wheel body 1321 is provided with circumferential baffles 171, which extend along the axial direction of the assembly wheel body 1321 to connect between two adjacent axial limiting protrusions 142, and the circumferential baffles 171 are disposed within the clamping spaces 172.

[0137] For example, in combination Figures 9 to 12As shown, in one embodiment of this application, along the circumferential direction of the annular mounting body 1322, the second limiting stop 1411 disposed on the first mounting body 13221 and the second limiting stop 1411 disposed on the second mounting body 13222 are correspondingly adjacent, and in the circumferential direction of the annular mounting body 1322, the two adjacent second limiting stop 1411 are spaced apart, so that the two adjacent second limiting stop 1411 form a clamping space 172. Furthermore, in the assembly wheel body 1321, the assembly wheel body 1321 is provided with a circumferential baffle 171, the circumferential baffle 171 is constructed as a strip, and the circumferential baffle 171 extends along the axial direction of the assembly wheel body 1321. In this assembled state, with the annular mounting body 1322 and the assembly wheel body 1321 in place, the circumferential stop 171 is located within the clamping space 172. Since the circumferential stop 171 is sandwiched between two adjacent second limiting edges 1411 in the circumferential direction of the annular mounting body 1322, the two second limiting edges 1411 abut against the circumferential stop 171, thereby achieving the effect of upper-limiting engagement between the annular mounting body 1322 and the assembly wheel body 1321 in the circumferential direction of the second shaft body 132. Furthermore, along the axial direction of the annular mounting body 1322, a third limiting edge 1412 is disposed outside the second limiting edges 1411 to prevent interference between the third limiting edge 1412 and the circumferential stop 171.

[0138] See Figure 13 As shown, in some embodiments of this application, the second shaft 132 is a one-piece molded part, and the second shaft 132 is provided with an installation space 132a and a flange 132b, and a receiving notch 132c is provided in the flange 132b. See also... Figure 13 As shown, the first shaft 131 and the second shaft 132 can be separate components, and the first shaft 131 and the second shaft 132 can be assembled by a plug-in connection. However, this application is not limited to this; for example, see [reference needed]. Figure 9 As shown, the first shaft 131 and the second shaft 132 are integral parts.

[0139] See Figures 1 to 3As shown, the cleaning device 200 according to this application includes a housing 201, a waste storage unit 202, a negative pressure generator 203, and a roller brush 100. The housing 201 includes a main body 2011 and a brush part 2012, wherein the waste storage unit 202 and the negative pressure generator 203 are both disposed in the main body 2011, and the brush part 2012 is provided with a roller brush cavity 20120 and an anti-rolling member 20121, the anti-rolling member 20121 being disposed at the suction port of the roller brush cavity 20120. A negative pressure channel 2013 is provided inside the main body 2011, the negative pressure channel 2013 connecting the roller brush cavity 20120 and the waste cavity 2020 of the waste storage unit 202, and the negative pressure generator 203 is configured to drive fluid to flow along the negative pressure channel 2013 from the roller brush cavity 20120 to the waste cavity 2020. The roller brush 100 is assembled in the roller brush cavity 20120. The roller brush 100 includes a roller component 1 and an electrostatic adsorption component 3. The electrostatic adsorption component 3 is disposed on the roller component 1 and along the axial direction of the roller brush 100. The electrostatic adsorption component 3 is located between two adjacent anti-rolling components 20121.

[0140] For example, see Figures 1 to 4 As shown, in some embodiments of this application, when the cleaning device 200 is in operation, the roller brush 100 rotates in a self-rotating manner within the roller brush cavity 20120. For example, the roller brush 100 can be rotated using the negative pressure airflow generated by the negative pressure generator 203 (when the negative pressure generator 203 is working, the airflow flows from the outside of the roller brush cavity 20120 into the roller brush cavity 20120 and flows along the negative pressure channel 2013 to the dirt cavity 2020). Alternatively, the cleaning device 200 may also include a drive mechanism, which is connected to the roller 1 of the roller brush 100 in a driving manner, so that the roller brush 100 rotates in a self-rotating manner within the roller brush cavity 20120 under the driving action of the drive mechanism.

[0141] Because the electrostatic adsorption element 3 is located on the roller 1, the roller brush 100, in its rotating state, causes the electrostatic adsorption element 3 to continuously move in a circular motion. The moving electrostatic adsorption element 3 generates static electricity through friction with the surface to be cleaned (e.g., a bed sheet), causing fine particles (e.g., dust, hair) on the surface to be cleaned to be adsorbed onto the electrostatic adsorption element 3 due to electrostatic adsorption force. Simultaneously, when the cleaning equipment 200 is in operation, the negative pressure generator 203 generates negative pressure, causing gas to flow from the outside of the roller brush cavity 20120 into the roller brush cavity 20120, and then flow along the negative pressure channel 2013 towards the dirt chamber 2020. Therefore, the fine particles adsorbed by the electrostatic adsorption element 3 due to electrostatic adsorption force eventually flow into the dirt chamber 2020 along with the gas flowing due to the negative pressure.

[0142] For example, see Figure 1As shown, in one embodiment of this application, the brush portion 2012 has four anti-rolling members 20121 disposed on the inlet side of the roller brush cavity 20120. The anti-rolling members 20121 can be constructed as baffles. When the negative pressure generator 203 generates negative pressure airflow, the anti-rolling members 20121 can effectively prevent objects such as bed sheets from being sucked into the roller brush cavity 20120, thereby preventing bed sheets and other objects from rolling around on the roller brush 100. In addition, combined with Figures 1 to 3 As shown, when the roller brush 100 is assembled inside the roller brush cavity 20120, the electrostatic adsorption component 3 is located between two adjacent anti-rolling components 20121 in the axial direction of the roller brush 100, thus reducing the influence of the anti-rolling component 20121 on the electrostatic effect. It should be understood that, since the outer diameter of the electrostatic adsorption component 3 is non-deformable and relatively large, if the electrostatic adsorption component 3 and the anti-rolling component 20121 overlap in the axial direction, large particles can easily get stuck between the two (i.e., the electrostatic adsorption component 3 and the anti-rolling component 20121).

[0143] In summary, the cleaning device 200 according to this application includes a housing 201, a waste storage unit 202, a negative pressure generator 203, and a roller brush 100. The brush portion 2012 of the housing 201 is provided with a roller brush cavity 20120 and an anti-rolling member 20121 located at its suction inlet. The roller brush 100 is assembled within the roller brush cavity 20120, and the electrostatic adsorption member 3 on its roller 1 is axially positioned between two adjacent anti-rolling members 20121. During operation, the rotation of the roller brush 100 causes the electrostatic adsorption member 3 to generate static electricity through friction, adsorbing fine particles; the negative pressure generator 203 drives airflow along the negative pressure channel 2013 to transport the adsorbed material to the waste storage cavity 2020. The anti-rolling member 20121 prevents objects from being sucked into the roller brush cavity 20120, and the electrostatic adsorption member 3 and the anti-rolling member 20121 are offset axially to avoid large particles getting stuck. Therefore, the cleaning equipment 200 according to this application not only has better cleaning capabilities, but also ensures the reliability of the cleaning equipment 200 in use, thereby improving the user experience.

[0144] See Figures 1 to 3As shown, in some embodiments of this application, the negative pressure channel 2013 includes an upstream channel section 2013a and a downstream channel section 2013b. The upstream channel section 2013a connects the brush chamber 20120 and the waste chamber 2020, while the downstream channel section 2013b connects the waste chamber 2020 and the negative pressure generator 203. Thus, when the negative pressure generator 203 is in operation, the driving gas first flows into the brush chamber 20120 from the outside, and then sequentially flows along the upstream channel section 2013a, the waste chamber 2020, and the downstream channel section 2013b. When the particulate matter flowing with the airflow passes through the waste chamber 2020, the waste storage device 202 can intercept the particulate matter in the waste chamber 2020 and only allow gas to flow from the waste chamber 2020 into the downstream channel section 2013b. Furthermore, along the extension direction of the upstream channel section 2013a, the suction port of the upstream channel section 2013a is positioned opposite to the electrostatic adsorption component 3 in the direction of fluid flow. This allows for more effective use of negative pressure airflow to draw in the substances gathered on the electrostatic adsorption component 3, thereby enhancing the cleaning capability of the cleaning equipment 200.

[0145] See Figure 1 As shown, in some embodiments of this application, the cleaning device 200 may further include a lamp assembly 204 disposed at the bottom of the housing 201. The lamp assembly 204 includes at least an ultraviolet (UV) lamp core configured to emit UV light for disinfection. For example, the UV lamp core emits UV light to disinfect and sterilize bed sheets, and can also disinfect mites in the bed sheets. Additionally, the lamp assembly 204 may also include an LED lighting core configured for illumination.

[0146] See Figure 3 As shown, in some embodiments of this application, the lower boundary of the electrostatic adsorption member 3 is located below the anti-rolling member 20121 in the height direction of the housing 201. In other words, the electrostatic adsorption member 3 protrudes outward from the anti-rolling member 20121 in the height direction of the housing 201. This ensures that the electrostatic adsorption member 3 is in contact with the surface to be cleaned (such as a bed sheet) when the cleaning device 200 is placed on it. That is, the electrostatic adsorption member 3 provides support for the housing 201 in the height direction. Thus, during the movement of the cleaning device 200, the electrostatic adsorption member 3 acts as a wheel, thereby reducing the driving force required for the user to move the cleaning device 200.

[0147] See Figure 3 As shown, in some embodiments of this application, the main body 2011 is provided with a handle 20110. This allows the user to grip the cleaning device 200 via the handle 20110. This facilitates picking up the cleaning device 200 and allows the user to move the cleaning device 200 across the surface to be cleaned.

[0148] See Figure 3 As shown, in some embodiments of this application, in the moving direction of the cleaning device 200, the distance between the midpoint of the handle 20110 and the electrostatic adsorption member 3 is L1, and the length of the handle 20110 is L2, satisfying the relationship: L1 < 2L2. For example, see [reference needed]. Figure 3 As shown, the cleaning device 200 moves along the length of the housing 201. Thus, it can also be understood that in the length of the housing 201, the distance between the midpoint of the handle 20110 and the electrostatic adsorption component 3 is L1, and the length of the handle 20110 is L2, satisfying the relationship: L1 < 2L2.

[0149] For details, please refer to Figure 3 As shown, the handle 20110 is equivalent to the lever arm through which the user applies operating force, and the electrostatic adsorption component 3 is the fulcrum where the device contacts the ground. The distance L1 between the midpoint of the handle 20110 and the electrostatic adsorption component 3 in the direction of movement of the cleaning device 200 is equivalent to the lever arm length from the fulcrum (i.e., the electrostatic adsorption component 3) to the point of force application (i.e., the handle 20110). By setting L1 < 2L2, the lever arm length is effectively controlled. According to the lever principle (torque equals the product of force and lever arm), under the same pushing / pulling force, the shorter the lever arm (i.e., the distance L1 between the midpoint of the handle 20110 and the electrostatic adsorption component 3 in the direction of movement of the cleaning device 200), the smaller the torque the user needs to overcome. Thus, it requires less effort from the user when holding the handle 20110 to drive the cleaning device 200.
