[0019] Preferred embodiments of the present application will be described below with reference to the drawings, and it should be understood that the preferred embodiments described herein are for illustrative and interpretive purposes only and do not limit the present application.

[0020] In a first embodiment, this embodiment provides a roller brush bracket. Figure 1 is a schematic diagram of the structure of the roller brush bracket provided in this embodiment. Figure 2 is a schematic diagram of the structure of the housing provided in this embodiment. Figure 3 is a schematic diagram of the structure of the housing and nozzle provided in this embodiment.

[0021] As shown in FIGS. 1 to 3, the roller brush bracket of this embodiment includes a housing 1, a nozzle 2, and a cover plate 3. The housing 1 includes a cavity and an air passage 11. The cavity is used to accommodate the roller brush, and the air passage 11 includes an air outlet 12 and a relief port 13. The nozzle 2 is disposed at the air outlet 12. The cover plate 3 is disposed at the relief port 13 and closes the relief port 13. The housing 1, the nozzle 2, and the cover plate 3 are of an integral structure.

[0022] In some examples, as shown in FIGS. 1 to 3, the cavity and the air passage 11 communicate integrally and are used to accommodate the roller brush. To facilitate demolding, the relief port 13 is close to the air outlet 12.

[0023] In some examples, as shown in FIGS. 1 to 3, the shape of the relief port 13 is square. By arranging it in this way, the processing and manufacturing become easy. In addition, in other embodiments, the shape of the relief port 13 may also be circular, elliptical, or other polygons as long as it can facilitate the demolding of the nozzle 2 from the air outlet 12 and prevent interference between the air passage 11 on the housing 1 and the demolding of the nozzle 2, and there is no particular limitation in this embodiment.

[0024] In some examples, as shown in FIGS. 1 to 3, in the length direction of the air passage 11, the width of the relief port 13 is larger than the width of the air outlet 12. By arranging it in this way, the demolding of the nozzle 2 is facilitated.

[0025] In some examples, referring to FIG. 1, the material of the nozzle 2 is flexible plastic. Flexible plastic, also called soft rubber, is formed by injection molding of plastic, has a relatively soft touch at room temperature, does not require vulcanization treatment, and has excellent heat resistance and mechanical properties.

[0026] In some examples, as shown in FIG. 1, the integral structure of the housing 1, the nozzle 2, and the cover plate 3 is formed by three injection moldings.

[0027] Specifically, the housing 1 of the roller brush bracket is formed by the first injection molding, and as shown in Figure 2, the formed housing 1 is equipped with an air passage 11, which has an air outlet 12 and a relief opening 13. The relief opening 13 is used to release the inner slide core of the nozzle 2 in the second injection molding, and the nozzle 2 is formed at the air outlet 12 by the second in-mold injection molding, and as shown in Figure 3, when the inner slide core of the nozzle 2 is released during the second injection molding, the slide core is pulled out from the relief opening 13, and the cover plate 3 is formed at the relief opening 13 by the third in-mold injection molding, thereby completing the overall injection molding of the roller brush bracket, and as shown in Figure 1, the housing 1, nozzle 2, and cover plate 3 form an integrated structure.

[0028] The roller brush bracket provided in this embodiment comprises a housing 1, a nozzle 2, and a cover plate 3. Since the housing 1, nozzle 2, and cover plate 3 are integrally structured, the air passage 11 forms a complete sealing structure, avoiding sealing failures and air leaks, improving the cleaning performance of the cleaning equipment, and preventing dust from accumulating due to the absence of gaps.

[0029] In some embodiments, referring to Figure 1, the materials of the housing 1 and the cover plate 3 are the same.

[0030] In some examples, referring to Figure 1, the material of the housing 1 and cover plate 3 is ABS material.

[0031] Specifically, ABS material refers to acrylonitrile-butadiene-styrene copolymer, a thermoplastic polymer structural material that is strong, tough, and easy to process and mold. By using ABS material for both housing 1 and cover plate 3, a good connection between cover plate 3 and housing 1 is possible, and the amount of deformation can be kept within a controllable range of approximately 0.2 mm.

[0032] In some other examples, referring to Figure 1, the material of the housing 1 and cover plate 3 is polyolefin.

[0033] Specifically, polyolefins typically refer to a type of thermoplastic resin obtained by polymerizing or copolymerizing α-olefins such as ethylene, propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, and 4-methyl-1-pentene, as well as some cyclic olefins, either individually or copolymerically. They have the advantages of being readily available and inexpensive, and being easy to process and mold.

[0034] In several other examples, referring to Figure 1, the material of the housing 1 and cover plate 3 is polyacetal.

[0035] Specifically, polyacetal, also known as acetal resin, is a thermoplastic crystalline polymer that possesses advantages such as high fatigue strength, excellent wear resistance, low water absorption, high surface hardness, good rigidity, excellent size stability, high product size accuracy, and excellent lubricity.

[0036] In some other examples, referring to Figure 1, the material of the housing 1 and cover plate 3 is polycarbonate.

[0037] Specifically, polycarbonate is a tough thermoplastic resin with high strength, high modulus of elasticity, high impact strength, excellent fatigue resistance, good size stability, low creep (hardly changes even under high temperature conditions), high transparency, and easy dyeing.

[0038] Since the housing 1 and cover plate 3 in this embodiment use the same material, they have the same performance, good connections are easily achieved in the injection molding process, and the sealing performance of the air passage is effectively improved.

[0039] In some embodiments, referring to Figure 1, the materials of the housing 1 and the cover plate 3 are different.

[0040] In some examples, referring to Figure 1, the material of the housing 1 is ABS material. The cover plate 3 has a composite structure and comprises an ABS material layer and a glass fiber layer.

[0041] As an example, the arrangement of the ABS material layer and the glass fiber layer of the cover plate 3 includes, but is not limited to, a stacked arrangement, a reciprocating cross arrangement, and a mixed arrangement.

[0042] For example, the ratio of ABS material to glass fiber in cover plate 3 differs, with a difference of 5% to 30%.

[0043] Specifically, the cover plate 3 contains ABS material and glass fiber, has good compatibility with the housing 1 made of ABS material, and has a low shrinkage rate.

[0044] In some other examples, referring to Figure 1, the material of the housing 1 is ABS material. The cover plate 3 is a composite structure comprising an ABS material layer, a glass fiber layer, and a polycarbonate layer.

[0045] As an example, the arrangement of the ABS material layer, glass fiber layer, and polycarbonate layer of the cover plate 3 includes, but is not limited to, a stacked arrangement, a reciprocating cross arrangement, and a mixed arrangement.

[0046] For example, the content ratios of ABS material, glass fiber, and polycarbonate in cover plate 3 differ, ranging from 5% to 30%.

[0047] Specifically, the cover plate 3 comprises ABS material, glass fiber, and polycarbonate. That is, it has good compatibility with the housing 1 made of ABS material and has a relatively small shrinkage rate, which is advantageous for forming a good connection between the cover plate 3 and the housing 1.

[0048] In some other examples, referring to Figure 1, the material of housing 1 is ABS material. Cover plate 3 has a composite structure and comprises a glass fiber layer and a polycarbonate layer.

[0049] As an example, the arrangement of the glass fiber layer and polycarbonate layer of the cover plate 3 includes, but is not limited to, a stacked arrangement, a reciprocating cross arrangement, and a mixed arrangement.

[0050] For example, the ratio of glass fiber to polycarbonate in cover plate 3 differs, with a difference of 5% to 30%.

[0051] Specifically, the cover plate 3 contains glass fiber and polycarbonate. Glass fiber has excellent insulation, high heat resistance, excellent corrosion resistance, and high mechanical strength. Polycarbonate has high strength, a high modulus of elasticity, high impact strength, excellent fatigue resistance, good size stability, and low creep, compensating for the shortcomings of glass fiber, such as its brittleness and low wear resistance. The material of the cover plate 3, which contains glass fiber and polycarbonate, not only has good compatibility with the ABS material housing 1 but also has a relatively small shrinkage rate.

[0052] In some other examples, referring to Figure 1, the material of the housing 1 is ABS material. The cover plate 3 has a composite structure and comprises a polyamide layer and a glass fiber layer.

[0053] As an example, the arrangement of the polyamide layer and glass fiber layer of the cover plate 3 includes, but is not limited to, a stacked arrangement, a reciprocating cross arrangement, and a mixed arrangement.

[0054] For example, the ratio of polyamide to glass fiber in cover plate 3 varies, with a difference of 5% to 30%.

[0055] Specifically, the cover plate 3 contains polyamide and glass fiber. Polyamide, commonly known as nylon, has advantages such as toughness, wear resistance, self-lubrication, and a wide operating temperature range, and is also low in cost, thus compensating for the disadvantages of glass fiber, such as its brittleness and low wear resistance. The material of the cover plate 3, containing polyamide and glass fiber, not only has relatively good compatibility with the ABS material housing 1, but also reduces the rate of shrinkage.

[0056] In this embodiment, the materials of the housing 1 and the cover plate 3 are different, which reduces the restrictions on the material of the cover plate 3.

[0057] In some embodiments, as shown in Figures 1-3, the air passage 11 comprises a first passage 111 and a second passage 112 arranged adjacent to each other. The air outlet 12 communicates with the first passage 111. The relief opening 13 extends from the side of the first passage 111 closest to the air outlet 12 to the side of the second passage 112 furthest from the air outlet 12.

[0058] In some examples, as shown in Figures 1-3, the first passage 111 and the second passage 112 are each used to house one roller brush and are in communication with each other. This arrangement makes the structure more rational and is advantageous for the airflow within the air passage 11.

[0059] In this embodiment, the escape port 13 extends from the side of the first passage 111 closest to the air outlet 12 to the side of the second passage 112 furthest from the air outlet 12, providing sufficient space for the release of the nozzle 2 and avoiding interference.

[0060] In a second embodiment, this embodiment also provides a cleaning device. The cleaning device of this embodiment comprises a device body, at least one of the roller brush brackets, and at least one roller brush. The roller brush bracket is positioned on the device body. If there are multiple roller brushes, the multiple roller brushes may be positioned on the roller brush bracket simultaneously.

[0061] As can be understood, the cleaning equipment in this embodiment may be a robotic vacuum cleaner, a wet / dry vacuum cleaner, or any other cleaning equipment that meets the requirements.

[0062] In some examples, a roller brush comprises a support component and a cleaning component positioned outside the support component. The support component can be made from a high-strength support material such as metal pipe or rigid plastic, while the cleaning component can be made from a material with superior cleaning effect, such as foamed rubber, foam, nonwoven fabric, cotton cloth, or fleece. This arrangement not only improves the overall structural strength of the roller brush but also provides excellent cleaning capabilities.

[0063] In some examples, the cleaning equipment further comprises a fan unit and a dustbin, the fan unit being connected to a nozzle on a roller brush bracket, each pair of roller brushes being positioned on one roller brush bracket and having some interference with the ground, the roller brushes sweeping up debris from the ground and drawing it into the airflow path, which is then sucked into the dustbin by a suction-force gas generated by the fan unit and passing through the dustbin unit, thereby collecting the debris in the dustbin unit.

[0064] As can be understood, the cleaning device may further include a drive system, a sensing system, a control module, an energy system, and a human-machine interaction system. Through the cooperation of these systems, the cleaning device can move autonomously and perform its cleaning function. The functional elements constituting each of these systems in the cleaning device are integrated and arranged within the device body.

[0065] The cleaning device provided in this embodiment, having the roller brush bracket of the above embodiment, has superior cleaning performance, is less prone to dust accumulation, and facilitates daily maintenance and cleaning.

[0066] As those skilled in the art will understand, the above advantageous methods can be freely combined or superimposed, as long as they do not contradict each other.

[0067] The foregoing are merely preferred embodiments of the present application and do not limit it. Any modifications, equivalent substitutions, and improvements made without departing from the spirit and principles of the present application should all be included in the claims. The foregoing are merely preferred embodiments of the present application, and it should be noted that a person skilled in the art could make several further improvements and modifications without departing from the technical principles of the present application, and these improvements and modifications should also be considered within the scope of the claims.
