Description

Technical Field

[0001] The present disclosure relates to the technical field of household appliances, and in particular to a roller brush, a floor brush and a cleaning device. Background Art

[0002] With the development of science and technology, cleaning equipment is widely used in daily life to replace manual cleaning. The main principle of cleaning equipment is to spray clean water onto the roller brush, and through the rotation of the roller brush, the dirt on the target surface is adsorbed onto the roller brush, and then the roller brush is squeezed to squeeze out the sewage on the roller brush and sucked into the sewage bucket, thereby cleaning the target surface.

[0003] Since there is no heat dissipation device in the roller brush in the prior art, heat dissipation is usually increased by reducing the working power of the cleaning device or using materials with better heat dissipation. This still results in the heat generated inside the roller brush being unable to dissipate after the cleaning device has been working for a long time. The heat accumulated in the roller brush will affect the working temperature of the roller brush and will be transferred to other parts, such as the scrubbing layer on the outer surface of the roller brush housing, resulting in a relatively short service life of the roller brush and its parts.

[0048] The present disclosure provides a roller brush. Figure 1 is a schematic diagram of the structure of a roller brush 100 according to an exemplary embodiment; Figure 1 As shown, the roller brush 100 includes:

[0049] The roller brush housing 1 has an air inlet 11 and an air outlet 12;

[0050] A driving assembly 2, located in the roller brush housing 1, and used for driving the roller brush housing 1 to rotate;

[0051] The rotating assembly 3 is located in the roller brush housing 1 and connected to the driving assembly 2 , and is used for rotating under the drive of the driving assembly 2 to introduce air from the air inlet 11 into the roller brush housing 1 and discharge it from the air outlet 12 .

[0052] In the embodiment of the present disclosure, the roller brush 100 can be applied to an electronic device, and the electronic device can be any device used for cleaning. The roller brush 100 is a module in the electronic device that can rotate and clean the target surface.

[0053] Exemplarily, the electronic device may be, but is not limited to, a floor scrubber, a sweeping robot, a mopping robot, a cleaning vehicle, or a glass cleaning machine.

[0054] Exemplarily, the target surface may be, but is not limited to, a floor, a wall, a ceiling, glass, a tabletop, a car body, or a surface of other objects and parts.

[0055] In the disclosed embodiment, the specifications of the roller brush 100 are usually measured in terms of diameter and length. The diameter of the roller brush 100 is usually 10 to 15 cm; while the length varies depending on the purpose, such as 10 inches, 9 inches, 8 inches, 6 inches, and 4 inches. Large roller brushes are usually used to clean large surfaces, such as carpets; while small roller brushes are suitable for cleaning small surfaces, such as desktops. The roller brush 100 can be selected with appropriate specifications and materials according to specific purposes and scenarios.

[0056] In the disclosed embodiment, the roller brush housing 1 is a protective housing of the roller brush 100, which can protect the functional components inside the roller brush 100. The roller brush housing 1 can be made of plastic material, fiber, wool fabric or any other suitable material.

[0057] Exemplarily, plastic materials include but are not limited to ABS plastic (Aerylonitrile Butadiene Styrene). ABS plastic is a material with high strength, good toughness and easy processing, and has good insulation properties. It is almost unaffected by temperature, temperature and frequency and can be used in most environments.

[0058] In the disclosed embodiment, the roller brush housing 1 is generally cylindrical in shape.

[0059] In other embodiments, the roller brush housing 1 may be in any other shape without affecting the rotation of the roller brush housing 1.

[0060] In the embodiment of the present disclosure, the manufacturing process of the roller brush housing 1 includes but is not limited to an injection molding process, an extrusion process, a hollow blow molding process, a rotational molding process or a die-casting process.

[0061] In the disclosed embodiment, the roller brush housing 1 includes an air inlet for air to flow in and an air outlet for air to flow out.

[0062] In the embodiment of the present disclosure, the driving assembly 2 is used to provide power to drive the rotating assembly 2 connected thereto to generate motion. The type of motion may be telescopic motion, linear motion or rotational motion.

[0063] In the embodiment of the present disclosure, the driving component 2 may include a motor or a micro magnetic module, etc.

[0064] In some embodiments, there is a first gap between the driving assembly 2 and the inner surface of the roller brush housing 1; the distance of the first gap is a first distance. For example, the first distance may be 1 to 5 mm, which facilitates air flow through the first gap for better heat dissipation; on the other hand, it facilitates the disassembly and subsequent cleaning of the roller brush housing 1.

[0065] In the disclosed embodiment, the rotating component 3 is used to move under the drive of the driving component 2 to generate an airflow toward the driving component 2 .

[0066] In the embodiment of the present disclosure, the rotating assembly 3 may include a turbine or an impeller, etc. For example, the turbine may be a self-driven turbine, and for example, the impeller may be a suction impeller.

[0067] In some embodiments, there is a second gap between the rotating assembly 3 and the inner surface of the roller brush housing 1; the distance of the second gap is a second distance. Exemplarily, the second distance can be 3 to 8 mm, so as to avoid collision between the rotating assembly 3 and the inner surface of the roller brush housing 1, thereby reducing damage to the rotating assembly 3 and / or the roller brush housing 1, ensuring the operating performance of the rotating assembly 3 while reducing noise.

[0068] As mentioned above, in the related art, in order to achieve a better cleaning effect, the working power of the driving component 2 used in the roller brush shell 1 is getting larger and larger, which causes the temperature of the driving component 2 to rise after working for a long time and cannot effectively dissipate heat; and the heat is concentrated on the surface of the driving component and transferred to other components, resulting in a reduction in the service life of the roller brush and its components.

[0069] In contrast, in the disclosed embodiment, on the one hand, the roller brush in the disclosed embodiment drives the rotating assembly to rotate through the driving assembly, which can drive air to flow from the air inlet into the roller brush housing, flow through the driving assembly and be discharged from the air outlet; thereby, the air in the roller brush housing circulates, taking away the heat generated by the driving assembly during operation, and allowing the cleaning device to operate at a higher power while reducing the operating temperature of the driving assembly. On the other hand, it can also reduce the heat generated by the driving assembly from being transferred to other components, thereby extending the service life of the roller brush and its components, and reducing the cost of replacing the roller brush or its components.

[0070] In some embodiments, Figure 1 As shown, the air inlet 11 and the air outlet 12 are respectively located at opposite ends of the roller brush housing 1 ; the air entering through the air inlet 11 passes through the rotating assembly 3 and the driving assembly 2 in sequence and is discharged from the air outlet 12 .

[0071] In other embodiments, the air inlet 11 and / or the air outlet 12 are respectively located on the cylindrical circumference of the roller brush housing 1. It should be noted that in order to prevent liquid from entering the roller brush housing 1 when the roller brush moves, a sponge can be provided at the air inlet 11 and / or the air outlet 12.

[0072] In the disclosed embodiment, the air outlet 12 may be a through hole located at one end of the roller brush housing 1 for air outlet.

[0073] In some embodiments, the roller brush 100 may include an air outlet component;

[0074] The air outlet assembly is fixed between the air outlet 12 in the roller brush housing 1 and the driving assembly 2 .

[0075] In some embodiments, the air outlet assembly may be provided with a filter, and the filter is used to filter the air from the external environment entering the roller brush housing 1 when the driving assembly 2 is in a stationary state.

[0076] For example, Figure 1 The horizontal arrow in the figure indicates the flow direction of air, and the rotating arrow indicates the rotation direction of the roller brush housing 1. When the roller brush housing 1 rotates in the direction of the rotating arrow, air enters from the air inlet 11, passes through the rotating assembly 3 and the driving assembly 2 in sequence, and is discharged from the air outlet 12.

[0077] In the disclosed embodiment, on the one hand, by arranging the air inlet and the air outlet at opposite ends of the roller brush housing, the possibility of liquid entering the roller brush housing when the roller brush is in motion and damaging the parts in the roller brush housing can be reduced; on the other hand, the air flows through the rotating assembly and the driving assembly in sequence, realizing air circulation in the roller brush housing, and taking away the heat generated by the rotating assembly and the driving assembly. In addition, if the air inlet is a through hole at one end of the roller brush housing, there is no need to arrange an additional air outlet assembly, the structure is relatively simple, and the cost is saved.

[0078] In some embodiments, Figure 1 As shown, the roller brush 100 includes:

[0079] The air inlet assembly 4 is fixed between the air inlet 11 and the rotating assembly 3 in the roller brush housing 1; the air inlet assembly 4 is provided with a filter, and the air entering through the air inlet 11 is filtered by the filter and then passes through the rotating assembly 3 and the driving assembly 2 and is discharged from the air outlet 12.

[0080] In the disclosed embodiment, the air inlet assembly 4 is used to introduce external air into the roller brush housing 1. The air inlet assembly 4 can be made of metal material, plastic material, composite material or any other suitable material.

[0081] For example, the metal material may be stainless steel, galvanized sheet, etc.; the plastic material may be polyvinyl chloride (PVC), polypropylene (PP), etc.; the composite material may be fiberglass, polyurethane, etc.

[0082] In some embodiments, the air inlet assembly 4 is integrally formed with the roller brush housing 1, and the air inlet assembly 4 is not removable.

[0083] Exemplarily, the air inlet assembly 4 is welded to the roller brush housing 1 .

[0084] In some embodiments, the air inlet assembly 4 is detachably disposed in the roller brush housing 1 .

[0085] In the disclosed embodiment, by arranging the air inlet assembly between the air inlet and the rotating assembly, compared with only arranging the through hole as the air inlet, the air inlet area can be increased, thereby increasing the amount of air entering the roller brush housing, thereby improving the heat dissipation efficiency. In addition, by arranging a filter in the air inlet assembly, impurities and other large particles in the air entering the roller brush housing can be filtered out, reducing the occurrence of poor heat dissipation caused by dust accumulation in the roller brush housing, and also reducing the impact of impurities on the work of the components in the roller brush housing, thereby extending the service life of the roller brush and its components.

[0086] In some embodiments, Figure 2 As shown, the air inlet assembly 4 includes:

[0087] The cylindrical shell body 21 has openings at both ends, and the openings face the air inlet;

[0088] The axial core 22 is located in the cylindrical shell body 21 and is arranged along the opening direction of the cylindrical shell body 21;

[0089] A plurality of blades 23 are fixed to the cylindrical shell body 21 through the shaft core 22 in the cylindrical shell body 21, and there is a gap between two adjacent blades 23;

[0090] The filter is located in the cylindrical shell body 21 and is arranged between the air inlet 11 and the blades 23 .

[0091] In the embodiment of the present disclosure, the number of blades can be any suitable number. Figure 2 As shown, the number of blades is 8.

[0092] In some embodiments, the filter is located inside the cylindrical shell body 21 and can be arranged between the blades 23 and the rotating member 3 .

[0093] In some embodiments, the filter is located in the cylindrical shell body 21 and can be set in the gap between two adjacent blades 23; the filter is set in the gap between two adjacent blades 23 at one end close to the air inlet 11.

[0094] In the disclosed embodiment, the filter screen may be made of materials such as a cellulose filter screen, a polypropylene filter screen, a polyester filter screen, and a glass fiber filter screen.

[0095] In the disclosed embodiment, by arranging a plurality of blades in the air inlet assembly and supporting and fixing them through the axial part, the interior of the air inlet assembly can be made more stable, and the air (air) is taken in through a wheel-like structure, which helps the rotating assembly to better inhale the air and discharge the air from the air outlet. In addition, by arranging the filter between the blades and the air inlet, it is convenient to remove the filter for cleaning.

[0096] In some embodiments, Figure 2 and Figure 3 As shown, the outer surface of the cylindrical shell body 21 has a first protrusion 211 , the inner surface of the roller brush housing 1 has a groove 111 , and the air inlet assembly 4 and the roller brush housing 1 are fixed by the first protrusion 211 and the groove 111 .

[0097] In the disclosed embodiment, the air inlet assembly and the roller brush housing are fixed by clamping the first protrusion and the groove. The fixing method is simple and convenient, which facilitates the subsequent disassembly and cleaning of the air inlet assembly.

[0098] In some embodiments, Figure 4 and Figure 5 As shown, the driving assembly 2 includes a rotating shaft motor 21, and the roller brush 100 also includes:

[0099] The connecting member 5 is located inside the roller brush housing 1 and is connected to the rotating shaft of the rotating shaft motor 21 in the direction in which the rotating shaft of the rotating shaft motor 21 extends along the air inlet 11;

[0100] The connecting member 5 is provided with a second protrusion 51 , and the inner surface of the roller brush housing 1 is provided with a limiting groove 52 . The shaft motor 21 and the roller brush housing 1 are fixed via the second protrusion 51 and the limiting groove 52 .

[0101] In the embodiment of the present disclosure, the shaft motor 21 may include but is not limited to a DC motor, an AC motor or a stepping motor.

[0102] In the disclosed embodiment, the rotating shaft is connected to the transmission device through a coupling; the rotating shaft is used to transmit the rotational motion of the rotating shaft motor 21 to the transmission device, thereby driving the load. The rotating shaft can be made of steel, alloy or other materials with sufficient strength and rigidity.

[0103] In the embodiment of the present disclosure, the rotary shaft motor 21 generally includes a stator and a rotor. The rotor is coaxially arranged with the stator, and the rotor can rotate relative to the stator.

[0104] For example, one end of the rotating shaft can be fixed to the rotor of the rotating shaft motor 21 by interference fit or bonding. In this way, when the rotating shaft motor 21 is working, the rotor rotates relative to the stator, driving the rotating shaft to rotate together.

[0105] In the disclosed embodiment, the connecting member 5 is located between the shaft motor 21 and the rotating assembly 3 .

[0106] In the embodiment of the present disclosure, by providing a connecting member between the driving assembly and the rotating assembly, on the one hand, the driving assembly and the rotating assembly can be connected, so that when the driving assembly is working, the rotating assembly can be driven to rotate together through the connecting member, thereby eliminating the need to provide additional power to rotate the rotating assembly, thereby saving resource consumption; on the other hand, the second protrusion provided on the connecting member can be fixed to the limiting groove on the inner surface of the roller brush shell, so that the roller brush shell can be disassembled, which is convenient for subsequent cleaning or replacement of the roller brush shell.

[0107] In some embodiments, Figure 5 As shown, the connecting member 5 circumferentially covers the rotating shaft of the rotating shaft motor 21 , the outer circumferential surface of the connecting member 5 is provided with a plurality of second protrusions 51 , and the inner surface of the roller brush housing 1 is provided with a plurality of limiting grooves 52 matching the plurality of second protrusions 51 .

[0108] In the embodiment of the present disclosure, the second protrusions 51 may be of any appropriate number.

[0109] For example, Figure 5 As shown, the number of the second protrusions 51 is four, and the number of the limiting grooves 52 cooperating with the second protrusions 51 is also four.

[0110] In the embodiment of the present disclosure, by providing a plurality of second protrusions on the outer circumferential surface of the connecting member, the driving assembly and the rotating assembly connected to the connecting member can be better fixed, and the stability of the driving assembly and the rotating assembly arranged in the roller brush housing can be improved, and the accuracy of the driving assembly and the rotating assembly operating in the correct position can be improved. In addition, the possibility of accidental movement of the driving assembly and the rotating assembly is reduced, and the safety of the roller brush is improved.

[0111] In some embodiments, Figure 6 As shown, the rotating assembly 3 includes a base 31 and a plurality of blades 32;

[0112] The base 31 is fixed to one end of the connecting member 5 close to the air inlet 11;

[0113] The plurality of fan blades 32 are disposed on the base 31 and are spaced apart around the base 31 along the radial direction of the base 31 .

[0114] In the disclosed embodiment, the rotating component 3 may be any structure having rotatable blades 32, such as a self-driven turbine or an impeller.

[0115] In the disclosed embodiment, the rotating assembly 3 can be screwed and fixed to the connecting member 5 by a nut located at the inner center of the connecting member 5 .

[0116] In the disclosed embodiment, the fan blade 32 can be made of a hard material or a soft material. The hard material has high hardness, rigidity and wear resistance, and is not easy to deform and break; the hard material includes but is not limited to aluminum alloy, stainless steel or plastic. The soft material has good flexibility and toughness; the soft material includes but is not limited to rubber.

[0117] For example, the plastic may be polyester resin or glass fiber, etc.

[0118] In the disclosed embodiment, the fan blades 32 may be made of a material having a heat dissipation coefficient higher than a preset value, and may conduct heat while guiding the flow, so as to reduce the heat generated by the rotation of the fan blades 32 themselves.

[0119] In the embodiment of the present disclosure, radial direction is used to indicate a direction along the radius of the base 31 .

[0120] In the embodiment of the present disclosure, the number of fan blades can be any suitable number. Figure 5 As shown, the number of fan blades is 6.

[0121] In the disclosed embodiment, the fan blades 32 can be integrally formed with the base by an injection molding process; the fan blades 32 can also be detachably fixed to the base by bonding, snapping or screwing.

[0122] In the disclosed embodiment, by arranging the rotating component to rotate as the driving component is driven, an airflow can be generated from the rotating component to the driving component, thereby achieving cooling of the driving component; the rotation of the fan blades drives the flow of surrounding air to form a low-pressure area, thereby allowing the air to flow from the high-pressure area (air inlet component and external environment) to the low-pressure area (rotating component), thereby achieving gas circulation in the roller brush shell, and further better achieving heat dissipation in the roller brush shell.

[0123] In some embodiments, Figure 6 As shown, each of the blades 32 is swept back.

[0124] In the disclosed embodiment, the blade sweep is used to indicate that the blade airfoil bends backward along the rotation direction of the rotating component.

[0125] In the disclosed embodiment, the design of the swept blades can reduce the noise and vibration of the rotating assembly during operation, making the entire rotating assembly run more stably. In addition, by changing the shape of the blades, the airflow inside the roller brush housing is made more uniform and stable, improving the aerodynamic performance and thus the heat dissipation efficiency.

[0126] In some embodiments, Figure 1 As shown, the roller brush 100 further includes: a covering 6 with a cleaning effect, which is arranged on the outer surface of the roller brush housing 1 .

[0127] In the embodiment of the present disclosure, the covering 6 can be any covering with a cleaning effect, including but not limited to a brush or a mop.

[0128] For example, the brush can be a soft brush or a rubber brush. The soft brush can clean the scattered debris on the target surface; the rubber brush can clean the stubborn stains on the target surface, and has a better cleaning effect.

[0129] In some embodiments, the cover 6 can be mounted on the outer surface of the roller brush housing 1 by bonding or adhesive bonding, so that when the roller brush 100 is working, the cover 6 can clean the target surface.

[0130] Exemplarily, the cover 6 is detachably mounted on the outer surface of the roller brush housing 1, so that different covers 6 can be replaced according to different cleaning requirements.

[0131] In the disclosed embodiment, selecting a suitable cover for cleaning can meet the cleaning requirements in different cleaning scenarios and improve the applicability of the roller brush. In addition, the cover can be disassembled, which is convenient for cleaning and replacement of the cover.

[0132] The present disclosure also provides a floor brush, such as Figure 7 As shown, the floor brush 200 includes:

[0136] In some embodiments, the floor brush 200 may include a plurality of roller brushes 100, and the plurality of roller brushes 100 are arranged at intervals on the floor brush base 61. By adding the roller brushes 100, the contact between the cover 6 and the target surface to be cleaned can be increased, thereby improving the cleaning effect.

[0137] In some embodiments, the floor brush base 61 is provided with a rolling brush cavity, and the rolling brush 100 is disposed in the rolling brush cavity.

[0138] Exemplarily, the roller brush 100 may be disposed in the roller brush cavity in a detachable mounting manner, and the detachable mounting manner may facilitate replacement and cleaning of the roller brush 100 .

[0139] In some embodiments, the roller brush 100 may also be disposed in the floor brush in any other suitable manner.
