[0001] Floor Brush Structure and Cleaning Appliance

[0002] Technical Field

[0003] The present application relates to the technical field of cleaning equipment, and in particular, to a floor brush structure and a cleaning appliance.

[0004] Background of the Invention

[0005] As technology advances and living standards improve, household cleaning appliances such as vacuums and floor washers are becoming increasingly popular, with their functionalities expanding.

[0006] In the relevant art, a cleaning appliance can comprise a host and a floor brush assembly connected with the host, wherein the floor brush assembly is provided with an electric motor for driving the floor brush assembly to clean a surface to be cleaned (such as a floor). As brushed motors have advantages of low cost and stable operation, a brushed motor is generally used as the electric motor of the floor brush assembly. However, when working, brushed motors generate a relatively large amount of heat. A heat dissipating element can be provided inside the floor brush assembly to dissipate heat from the brushed motor.

[0007] However, as the heat dissipating element is arranged inside the floor brush assembly, it is not easy to transfer heat out, resulting in poor heat dissipation effect.

[0008] Summary of the Invention

[0009] Therefore, the present application provides a floor brush assembly and a cleaning appliance so as to solve the shortcomings in the relevant art.

[0010] In a first aspect, the present application provides a floor brush structure comprising a floor brush base, a heat conducting plate and at least one floor brush driving element, the floor brush base comprising a support and a side plate arranged on a side of the support, the floor brush driving element being arranged at the side plate, wherein the floor brush driving element and the support are on a same side of the side plate, while the heat conducting plate is arranged on a surface of the side plate on another side of the side plate which is opposite to said same side where the floor brush driving element and the support are.

[0011] Hence, with the floor brush driving element and the support on a same side of the side plate, that is, with the floor brush driving element arranged inside the floor brush structure, the floor brush structure can be driven by the floor brush driving element to accomplish floor cleaning; by arranging both the floor brush driving element and the heat conducting plate at the side plate, heat from the floor brush driving element is transferred to the heat conducting plate via the side plate, and yet with the heating conducting plate arranged on the surface of the side plate opposite to the support, that is, with the heat conducting plate arranged outside the floor brush base, a heat dissipating face of the heat conducting plate is on an outer side of the floor brush base, so that the heat conducting plate can transfer heat from the floor brush driving element to the outer side of the floor brush base to dissipate heat. Thus, heat dissipation effect is improved.

[0012] In a possible mode of realization, the floor brush structure provided by the present application comprises a brushroll and the floor brush driving element is used to drive the brushroll to roll to clean floor. This particularly relates to an application scenario of floor washers.

[0013] In a possible mode of realization, the floor brush structure provided by the present application further comprises a decorative element covering a surface of the heat conducting plate opposite to the side plate.

[0014] Thus, by covering the surface of the heat conducting plate with the decorative element, the aesthetic appearance of the floor brush structure can be enhanced.

[0015] In a possible mode of realization, in the floor brush structure provided by the present application, the side plate is provided with an insertion connection part, and the floor brush driving element is arranged to be inserted onto or into the insertion connection part.

[0016] Thus, not only does the insertion connection part provide a mounting position for the floor brush driving element, but also the insertion is convenient and facilitates the mounting of the floor brush driving element to the side plate.

[0017] In a possible mode of realization, in the floor brush structure provided by the present application, the insertion connection part is a through hole realized in the side plate, preferably an inner side wall of the through hole is provided with at least two position limiting parts configured to, when the floor brush driving element is inserted into the through hole, abut against the floor brush driving element.

[0018] Thus, by providing the insertion connection part as a through hole, the floor brush driving element arranged to be inserted into the through hole can make direct contact with the heat conducting plate, so that the floor brush driving element can quickly transfer heat it generates to the heat conducting plate. By providing the position limiting parts to limit the mounting position of the floor brush driving element, the mounting of the floor brush driving element to the side plate is facilitated, further improving the mounting efficiency of the floor brush driving element.

[0019] In a possible mode of realization, the floor brush structure provided by the present application further comprises at least two connection elements used to connect the heat conducting plate to the floor brush driving element. Preferably, the connection elements are screws, the heat conducting plate has corresponding connection holes for the screws to pass through, and the floor brush driving element is provided with screw holes or screw studs for threaded connection with the screws.

[0020] Thus, with the connection elements arranged to be inserted into the heat conducting plate and connecting the heat conducting plate to the floor brush driving element via the through hole, not only is the mounting of the heat conducting plate facilitated, but also the mounting of the floor brush driving element is achieved at the same time, thus improving the mounting efficiency of the heat conducting plate and the floor brush driving element. At the same time, by connecting the heat conducting plate to the floor brush driving element by means of the connection elements, the heat conducting plate and the floor brush driving element are in direct contact, thereby preventing any gap between the heat conducting plate and the floor brush driving element and facilitating the floor brush driving element to transfer heat it generates to the heat conducting plate.

[0021] In a possible mode of realization, in the floor brush structure provided by the present application, a mounting groove is provided on the surface of the side plate on which the heat conducting plate is arranged, and the heat conducting plate is embedded into the mounting groove. Preferably, in case in which a through hole is realized in the side plate as the insertion connection part and the floor brush driving element is inserted into the through hole, the through hole is located in the mounting groove.

[0022] Thus, with the through hole located in the mounting groove and the floor brush driving element inserted into the through hole, the floor brush driving element is also located in the mounting groove, and yet with the heat conducting plate embedded into the mounting groove, not only is a mounting position provided for the heat conducting plate, thereby facilitating the mounting of the heat conducting plate, but also the mounting position of the floor brush driving element is made to correspond to the location of the heat conducting plate so as to facilitate the connecting of the floor brush driving element to the heat conducting plate.

[0023] In a possible mode of realization, in the floor brush structure provided by the present application, the heat conducting plate is provided with at least two notches used to correspondingly avoid the position limiting parts. Thus, by providing the notches on the heat conducting plate to avoid the position limiting parts on the side plate, it is ensured that the heat conducting plate can be fully embedded into the mounting groove.

[0024] In a possible mode of realization, in the floor brush structure provided by the present application, the heat conducting plate is an aluminum plate.

[0025] Thus, as the aluminum plate has high thermal conduction efficiency and good thermal conduction effect, the floor brush driving element transfers heat to the aluminum plate and the aluminum plate quickly transfers heat out, thereby improving the heat dissipation efficiency of the floor brush driving element.

[0026] In a possible mode of realization, in the floor brush structure provided by the present application, the decorative element is a decorative sticker that is bonded to the heat conducting plate and the side plate.

[0027] Thus, with the side plate provided with the mounting groove and with the heat conducting plate embedded into the mounting groove of the side plate, there is a distance between an edge of the heat conducting plate and a corresponding edge of the side plate. Therefore, the decorative sticker can be bonded to the edge of the side plate and on the surface of the heat conducting plate opposite to the side plate, thereby enhancing the aesthetic appearance of the floor brush structure.

[0028] In a second aspect, the present application provides a cleaning appliance comprising a host and any floor brush structure disposed at the host and provided by the abovedescribed first aspect.

[0029] In addition to the technical problems solved by the embodiments of the present application, the technical features that constitute the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions that have been described above, other technical problems that can be solved by the floor brush structure and cleaning appliance provided by the present application, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the Detailed Description of the Invention.

[0044] First, those skilled in the art should understand that these modes of realization are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. Those skilled in the art can make adjustments to them as needed, so as to adapt to specific application scenarios.

For example, it can be a fixed connection, or it can be an indirect connection through an intermediary, or it can be internal communication between two elements or an interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific context.

[0046] Also, it should be noted that, in the description of the present application, the terms indicating orientation or position relationships, such as “upper,” “lower,” “front,” “back,” “vertical,” “horizontal,” “top,” “bottom,” “inside,” and “outside,” are based on the orientation or position relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0047] In addition, the terms “first” and “second” are used for the purpose of describing only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features referred to. Thus, a feature defined as “first” or“second” can explicitly or implicitly include one or more of the feature. In the description of the present application, unless otherwise indicated, “a plurality of’ means two or more.

[0048] As illustrated in the Background of the Invention, in the prior art, a cleaning appliance can comprise a host and a floor brush assembly connected to the host, and an electric motor is provided at the floor brush assembly to drive the floor brush assembly to clean a surface to be cleaned (such as a floor). As brushed motors have advantages of low cost and stable operation, a brushed motor is generally used as the electric motor of the floor brush assembly. But when working, the brushed motor generates a relatively large amount of heat. A heat dissipating element can be provided inside the floor brush assembly to dissipate heat from the brushed motor.

[0049] However, as the heat dissipating element is arranged inside the floor brush assembly, it is not easy for heat to be transferred outside, resulting in poor heat dissipation effect.

[0050] In view of the above-described problem, the present application provides a floor brush structure and a cleaning appliance. By providing the floor brush structure with the floor brush base, the heat conducting plate and at least one floor brush driving element, and by arranging the floor brush driving element and the support on a same side of the side plate, that is, arranging the floor brush driving element inside the floor brush structure, the floor brush structure can be driven by the floor brush driving element to accomplish floor cleaning; and by arranging both the floor brush driving element and the heat conducting plate at the side plate, heat from the floor brush driving element is transferred to the heat conducting plate via the side plate, and yet with the heat conducting plate located on a surface of the side plate opposite to the support, that is, with the heat conducting plate arranged outside the floor brush base, a heat dissipating face of the heat conducting plate is located on an outer side of the floor brush base, thus enabling the heat conducting plate to transfer heat from the floor brush driving element to the outer side of the floor brush base so as to dissipate heat. Thus, heat dissipation effect is improved.

[0051] The structures and various possible modes of realization of the floor brush structure and cleaning appliance provided by the present application are described in detail below in conjunction with specific modes of realization.

[0052] It should be noted that the floor brush structure provided by the present application can be adapted to different types of floor brush such as a brushroll and can be used in various different cleaning appliances. The following will take the floor brush structure comprising a brushroll as an example to describe the present application.

[0053] In reference to Figures 1 to 3, a floor brush structure provided by the present application comprises a floor brush base 100, a heat conducting plate 200 and at least one floor brush driving element 300 which is brushroll driving element 300 according to an embodiment of the present application. The floor brush base 100 comprises a support 110 and a side plate 120 disposed on a side of the support 110. The brushroll driving element 300 is arranged at the side plate 120, and the brushroll driving element 300 and the support 110 are located on a same side of the side plate 120. The heat conducting plate 200 is arranged on a surface of the side plate 120 opposite to the support 110.

[0054] It can be understood that, the side plate 120 is arranged along the Y direction as shown by an arrow in Figure 3, and the brushroll driving element 300 and the support 110 are located on a same side of the side plate 120, that is, the brushroll driving element 300 and the support 110 are both arranged in the X direction of the side plate 120 as shown by an arrow in Figure 3. In other words, the brushroll driving element 300 is disposed inside the floor brush structure, and thereby the floor brush structure can be driven by the brushroll driving element 300 to accomplish floor cleaning.

[0055] As an example, the brushroll driving element 300 can be a brushed motor. The present application does not limit the brushroll driving element 300 so long as it can drive the floor brush structure to work.

[0056] As an example, the brushroll driving element 300 can be provided as one or more. The present application does not limit the number of the brushroll driving element 300.

[0057] As an example, two brushroll driving elements 300 can be provided, with one brushroll driving element 300 provided on each side of the support 100. In other words, the brushroll driving elements 300 are arranged in succession along the Y direction as shown by an arrow in Figure 3, which can not only increase the driving force of the floor brush structure, but also ensure a balance of force on both sides of the support 110, thereby preventing cleaning efficiency from being affected by the different pressures on both sides of the floor brush structure during use.

[0058] Further, the brushroll driving element 300 and the heat conducting plate 200 are both disposed at the side plate 120, so that heat of the brushroll driving element 300 is transferred to the heat conducting plate 200 via the side plate 120.

[0059] Further, the heating conducting plate 200 is located on a surface of the side plate 120 opposite to the support 110, that is, the heat conducting plate 200 is arranged in a direction of the side plate 120 which is opposite to the X direction as shown by an arrow in Figure 3. In other words, the heat conducting plate 200 is arranged outside the floor brush structure, so that a heat dissipating face of the heat conducting plate 200 is located on an outer side of the floor brush base 100, thereby allowing the heat conducting plate 200 to transfer heat from the brushroll driving element 300 to the outer side of the floor brush base 100 to dissipate heat. Thus, heat dissipation effect is improved.

[0060] It can be understood that, by comparison, in the prior art, a heat dissipating element is arranged inside a floor brush assembly and it is not easy for heat to be transferred out thus resulting in relatively poor heat dissipation. In the floor brush structure and the cleaning appliance provided by the present application, by providing the floor brush structure with the floor brush base 100, the heat conducting plate 200 and at least one brushroll driving element 300, and by arranging the brushroll driving element 300 and the support 110 on a same side of the side plate 120, i.e., disposing the brushroll driving element 300 inside the floor brush structure, the floor brush structure can be driven by the brushroll driving element 300 to accomplish floor cleaning; by disposing both the brushroll driving element 300 and the heat conducting plate 200 at the side plate 120, heat of the brushroll driving element 300 is transferred to the heat conducting plate 200 via the side plate 120, and with the heat conducting plate 200 located on a surface of the side plate 120 opposite to the support 110, that is, with the heat conducting plate 200 arranged outside the floor brush base 100, the heat dissipating face of the heat conducting plate 200 is thus located on the outer side of the floor brush base 100, thus enabling the heat conducting plate 200 to transfer heat from the brushroll driving element 300 to the outer side of the floor brush base 100 to dissipate heat. Thus, heat dissipation effect is improved.

[0061] In some embodiments, in reference to Figure 3, a decorative element 400 is further comprised. The decorative element 400 covers the surface of the heat conducting plate 200 opposite to the side plate 120.

[0062] It can be understood that, by covering the surface of the heat conducting plate 200 with the decorative element 400, aesthetics of the floor brush structure can be improved.

[0063] It should be noted that, the decorative element 400 needs to be made of a material having a good breathability in order to avoid affecting the heat dissipation properties of the heat conducting plate 200.

[0064] Further, the decorative element 400 with various colors, patterns and designs can be used.

[0065] In some embodiments, in reference to Figure 3, the side plate 120 has an insertion connection part 121 , and the brushroll driving element 300 is arranged at the insertion connection part 121 by insertion.

[0066] It should be noted that, by providing the insertion connection part 121 , not only is a mounting position provided for the brushroll driving element 300, but also the insertion arrangement is convenient, so as to facilitate the mounting of the brushroll driving element 300 to the side plate 120, thereby improving the mounting efficiency of the brushroll driving element 300.

[0067] In some embodiments, in reference to Figures 4 to 8, the insertion connection part 121 is a through hole realized in the side plate 120. An inner side wall of the through hole is provided with at least two position limiting parts 122 configured to, when the brushroll driving element 300 is inserted into the through hole, abut against the brushroll driving element 300.

[0068] As an example, two or more position limiting parts 122 can be provided. The present application does not limit the number of the position limiting parts 122.

[0069] As an example, when two position limiting parts are provided, the two position limiting parts 122 can be a first position limiting section 1221 and a second position limiting section 1222. The first position limiting section 1221 can be trapezoidal or rectangular in shape, and the second position limiting section 1222 can be curved in shape. The present application does not limit the shape and size of the first position limiting section 1221 and the second position limiting section 1222. It can be understood that, by providing the insertion connection part 121 as a through hole, the brushroll driving element 300 arranged to be inserted into the through hole can make direct contact with the heat conducting plate 200, so that the brushroll driving element 300 can quickly transfer heat it generates to the heat conducting plate 200.

[0070] Further, by providing the position limiting part 122 to limit the mounting position of the brushroll driving element 300, the mounting of the brushroll driving element 300 to the side plate 120 is facilitated, thereby improving the efficiency of mounting the brushroll driving element 300.

[0071] It should also be noted that, the size of the through hole can be set based on the size of the brushroll driving element 300. The present application does not limit the size of the through hole so long as the brushroll driving element 300 can be inserted into the through hole.

[0072] In some embodiments, in reference to Figures 3 and 9, at least two connection elements 500 are further comprised. The connection elements 500 are provided to be inserted into the heat conducting plate 200 and are connected to the brushroll driving element 300 via the through hole.

[0073] As an example, the connection elements 500 can be screws, and the heat conducting plate 200 has corresponding connection holes 220 for the screws to pass through; the brushroll driving element 300 is provided with screw holes or screw studs for threaded connection with the screws. The present application does not limit the type of the connection elements 500 so long as they can connect the heat conducting plate 200 to the brushroll driving element 300.

[0074] As an example, two or more connection elements 500 can be provided. The present application does not limit the number of the connection elements 500.

[0075] It can be understood that, by providing the connection elements 500 inserted into the heat conducting plate 200 and connecting the heat conducting plate 200 to the brushroll driving element 300 via the through hole, not only is mounting of the heat conducting plate 200 facilitated, but also the mounting of the brushroll driving element 300 is achieved at the same time, thereby improving the mounting efficiency of the heat conducting plate 200 and the brushroll driving element 300.

[0076] Further, by connecting the heat conducting plate 200 and the brushroll driving element 300 by means of the connection elements 500, the heat conducting plate 200 and the brushroll driving element 300 are in direct contact, thereby avoiding any gap between the heat conducting plate 200 and the brushroll driving element 300 and facilitating the brushroll driving element 300 to transfer the heat it generates to the heat conducting plate 200.

[0077] In some embodiments, in reference to Figures 3 and 9, there is a mounting groove 123 on the surface of the side plate 120 opposite to the support 110. The through hole is within the mounting groove 123. The heat conducting plate 200 is embedded into the mounting groove 123.

[0078] It should be noted that, as the through hole is within the mounting groove 123 and the brushroll driving element 300 is inserted into the through hole, the brushroll driving element 300 is also within the mounting groove 123. Yet as the heat conducting plate 200 is embedded into the mounting groove 123, not only is a mounting position provided for the heat conducting plate 200 to facilitate the mounting of the heat conducting plate 200, but also the mounting position of the brushroll driving element 300 is made to correspond to the location of the heat conducting plate 200 so as to facilitate the connection of the brushroll driving element 300 to the heat conducting plate 200.

[0079] In some embodiments, in reference to Figures 3 and 9, the heat conducting plate 200 has at least two notches 210 used to correspondingly avoid the position limiting parts 122.

[0080] As an example, two or more notches 210 can be provided. The present application does not limit the number of the notches 210 so long as it corresponds to the number of the position limiting parts 122.

[0081] As an example, when two position limiting parts 122 are provided, there are also two notches 210. The two notches 210 can be a first notch 211 and a second notch 212. The first notch 211 can be trapezoidal or rectangular in shape, and the second notch 212 can be curved in shape. The present application does not limit the shape and size of the first notch 211 and the second notch 212 so long as they correspond to the shape and size of the position limiting parts 122.

[0082] It can be understood that, the notches 210 are provided on the heat conducting plate 200 to avoid the position limiting parts 122 on the side plate 120, ensuring that the heating conducting plate 200 matches the side plate 120. This enables the heat conducting plate 200 to be fully embedded into the mounting groove 123 on the side plate 120. As a result, not only is mounting of the heat conducting plate 200 facilitated, but also the heat conducting plate 200 can make direct contact with the brushroll driving element 300.

[0083] In some embodiments, the heat conducting plate 200 is an aluminum plate. It should be noted that, aluminum has good heat dissipation properties, with a thermal conductivity (from 0°C to 100°C) of 238 W / (m K). As its thermal conduction rate is relatively fast, aluminum can quickly transfer heat out, resulting in excellent heat dissipation effect.

[0084] It can be understood that, as the aluminum plate has high thermal conduction efficiency and good thermal conduction effect, the brushroll driving element 300 transfers heat to the aluminum plate and the aluminum plate quickly transfers heat out, thereby improving the heat dissipation efficiency of the brushroll driving element 300.

[0085] It should also be noted that, as the aluminum plate itself has good water resistance, which can prevent accumulated water on the floor surface from entering the interior of the brushroll structure during floor cleaning.

[0086] In some embodiments, in reference to Figures 4 and 5, the decorative element 400 is a decorative sticker that is bonded to the heat conducting plate 200 and the side plate 120.

[0087] As an example, the decorative sticker can have inherent adhesive properties, or it can be bonded to the heat conducting plate 200 and the side plate 120 by means of a doublesided tape. The present application is not limited thereto.

[0088] It should be noted that, as the side plate 120 is provided with the mounting groove 123 and the heat conducting plate 200 is embedded into the mounting groove 123 of the side plate 120, there is a distance between the edge of the heat conducting plate 200 and the corresponding edge of the side plate 120. Therefore, the decorative sticker can be bonded to the edge of the side plate 120 and on the surface of the heat conducting plate 200 opposite to the side plate 120, so as to enhance the aesthetic appearance of the floor brush structure.

[0089] The present application further provides a cleaning appliance comprising a host and a floor brush structure disposed at the host.

[0090] In the cleaning appliance, the specific structure and operation mode of the floor brush structure have been described in detail in the above-described embodiments, which are not described in detail again here.

[0091] Those skilled in the art can understand that, in the floor brush structure and cleaning appliance provided by the present application, the floor brush structure is provided with the floor brush base 100, the heat conducting plate 200 and at least one brushroll driving element 300: by arranging the brushroll driving element 300 and the support 110 on a same side of the side plate 120, that is, arranging the brushroll driving element 300 inside the floor brush structure, the floor brush structure can be driven by the brushroll driving element 300 to accomplish floor cleaning; and by arranging both the brushroll driving element 300 and the heat conducting plate 200 at the side plate 120, heat from the brushroll driving element 300 is transferred to the heat conducting plate 200 via the side plate 120, and yet with the heat conducting plate 200 arranged on the surface of the side plate 120 opposite to the support 110, that is, with the heat conducting plate 200 arranged outside the floor brush base 100, the heat dissipating face of the heat conducting plate 200 is on the outer side of the floor brush base 100, the heat conducting plate 200 can transfer heat from the brushroll driving element 300 to the outer side of the floor brush base 100 so as to dissipate heat. Thus, heat dissipation effect is improved.
