[0029] In order to make the object, technical solutions and advantages of the application clearer, the application will be described in detail below with reference to the drawings and specific embodiments.

[0030] Here, it should be noted that, in order to avoid obscuring the application due to unnecessary details, only structures and / or processing steps closely related to the solution of the application are shown in the drawings, and other details not closely related to the application are omitted.

[0031] It is also to be noted that the terms "comprising", "comprises" or any other variant thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0032] Referring to Figures 1 to 7 As shown in the figure, the brush assembly 100 of a preferred embodiment of the present application comprises a housing 1, a driving structure 2, a cleaning element (not shown) and a heat-conducting structure 3. The housing 1 has a receiving cavity 13 with an opening 14, the driving structure 2 is arranged in the receiving cavity 13 and configured to drive the cleaning element of the brush assembly 100 to move for cleaning a surface to be cleaned. The surface to be cleaned refers to a surface that needs to be cleaned, such as a floor surface, a table surface, etc. The heat-conducting structure 3 is arranged between the driving structure 2 and the housing 1, at least partially in direct contact with the driving structure 2 and at least partially exposed to the housing 1 through the opening 14, so as to contact and dissipate heat from the driving structure 2 through the heat-conducting structure 3, i.e. the heat on the driving structure 2 is conducted to the outside of the housing 1 through the direct contact between the heat-conducting structure 3 and the driving structure 2, so as to actively dissipate the heat on the driving structure 2 to the outside of the housing 1, prolong the service life of the driving structure 2, and avoid the problem of high temperature in the housing 1 and scalding of a person.

[0033] Further, the housing 1 comprises a bottom wall 11 facing the surface to be cleaned and a side wall 12 extending from the bottom wall 11 away from the bottom wall 11, and the bottom wall 11 and the side wall 12 jointly define the receiving cavity 13. A plurality of partitions are arranged in the receiving cavity 13, and the plurality of partitions divide the receiving cavity 13 into different chambers for respectively mounting the driving structure 2, an air duct assembly 4 and other components.

[0034] In some embodiments, the opening 14 includes a first opening 141 disposed on the bottom wall 11, and a first plane 331 of the heat-conducting structure 3 is exposed to the shell 1 through the first opening 141 and contacts the surface to be cleaned (e.g., the floor). Moreover, the heat-conducting structure 3 semi-surrounds the driving structure 2 and directly contacts the driving structure 2 to transfer the heat on the driving structure 2 to the surface to be cleaned through the first plane 331 of the heat-conducting structure 3 via the first opening 141. That is, the heat-conducting structure 3 transfers the heat on the driving structure 2 to the surface to be cleaned through the first plane 331 of the heat-conducting structure 3 via the first opening 141 in a way of directly contacting and conducting the heat. In this way, the driving structure 2 can be actively cooled, and the heat transferred to the surface to be cleaned can help to quickly dry the surface to be cleaned, prevent water stains on the surface to be cleaned, and improve the heat utilization rate.

[0035] In some embodiments, the opening 14 is disposed on the bottom wall 11 and the side wall 12. For example, in the present embodiment, the bottom wall 11 and the side wall 12 of the shell 1 are both provided with the opening 14. The opening 14 includes a first opening 141 disposed on the bottom wall 11 and a second opening 142 disposed on the side wall 12. The first opening 141 is configured such that the first plane 331 of the heat-conducting structure 3 is exposed to the shell 1 through the first opening 141 to transfer the heat on the driving structure 2 to the surface to be cleaned through the first plane 331 of the heat-conducting structure 3 via the first opening 141. In this way, the driving structure 2 can be actively cooled, and the heat transferred to the surface to be cleaned can help to quickly dry the surface to be cleaned, prevent water stains on the surface to be cleaned, and improve the heat utilization rate. The second opening 142 is configured such that the second plane 332 of the heat-conducting structure 3 is exposed to the shell 1 through the second opening 142 to transfer the heat on the driving structure 2 away through the second plane 332 of the heat-conducting structure 3 via the second opening 142, thereby actively cooling the driving structure 2 and improving the service life thereof. By providing the first opening 141 and the second opening 142, the driving structure 2 can be actively cooled through two different heat transfer paths, and the cooling efficiency is high. It should be noted that, in other embodiments, the opening 14 can be provided only on the bottom wall 11 or only on the side wall 12, and the present application does not limit this.

[0036] The brush assembly 100 further includes an air duct assembly 4, a dirt suction opening 5, and a dirt suction channel 6 communicating the air duct assembly 4 and the dirt suction opening 5.

[0037] The air duct assembly 4 is disposed in the receiving cavity 13 of the shell 1, and an air outlet thereof communicates with the dirt suction opening 5 through the dirt suction channel 6. Preferably, the air duct assembly 4 is disposed opposite the dirt suction opening 5 to reduce wind loss and improve the dirt suction efficiency.

[0038] The suction port 5 is arranged at the side of the shell 1, especially at the longer side, so as to increase the area of the suction port 5 as much as possible, thereby facilitating the suction of larger garbage into the garbage can through the suction port 5.

[0039] Further, the suction channel 6 is in the shape of a trumpet mouth and has oppositely arranged inclined side walls 61. The inclined side walls 61 are formed by the side wall 12 of the shell 1. The opening 14 includes a second opening 142 arranged on the inclined side wall 61, and the heat conduction structure 3 is at least partially exposed in the suction channel 6 through the second opening 142. In this way, the heat on the driving structure 2 can be transmitted to the suction channel 6 through the heat conduction structure 3, so that the garbage on the surface to be cleaned is heated, thereby facilitating the suction of the garbage into the suction channel 6. Moreover, the heat can be guided into the suction channel 6 through the second opening 142 on the inclined side wall 61, so that the heat can be quickly taken away by the air flow of the air duct assembly 4 or the water stain on the surface to be cleaned when the cleaning device is working, so as to achieve the purpose of rapid heat dissipation. In addition, the air flow generated by the air duct assembly 4 can also help the heat conduction structure 3 to dissipate heat, thereby accelerating the heat dissipation efficiency. That is, when the second opening is arranged on the inclined side wall 61 of the suction channel 6, the second plane 332 of the heat conduction structure 3 is exposed in the suction channel 6, at this time, the heat on the driving structure 2 can be transmitted to the suction channel 6 through the contact heat dissipation and convection heat dissipation.

[0040] The driving structure 2 is fixed in the mounting cavity of the shell 1 to drive the cleaning member of the brush assembly 100 to move to clean the surface to be cleaned. In the embodiment, the driving structure 2 is arranged at the side of the air duct assembly 4 and is located in a different cavity from the air duct assembly 4, so as to avoid mutual interference. The driving structure 2 is a motor, and the brush assembly 100 includes a first cleaning member (not shown) and a second cleaning member (not shown), and the motor is fixedly arranged between the first cleaning member and the second cleaning member to simultaneously drive the first cleaning member and the second cleaning member to rotate circumferentially to clean the surface to be cleaned. In other embodiments, the brush assembly 100 can include only one cleaning member, or the driving structure 2 drives one of the first cleaning member and the second cleaning member to rotate, and the other one rotates in an auxiliary manner, which is not limited in the present application.

[0041] The heat conduction structure 3 is fixed on the shell 1 and arranged below the driving structure 2 between the driving structure 2 and the shell 1. The heat conduction structure 3 can be fixed on the shell 1 by commonly used fixing methods such as screws and adhesives, which are not limited in the present application.

[0042] The heat-conducting structure 3 comprises an arc surface 311 facing one side of the driving structure 2 and a flat surface 33 facing one side of the shell 1. The heat-conducting structure 3 is at least partially surrounded by the driving structure 2 through the arc surface 311 and at least partially exposed to the shell 1 through the flat surface 33. The driving structure 2 is wrapped by the arc surface 311 so that the heat-conducting structure 3 can have a larger contact area with the driving structure 2, thereby making the heat-conducting structure 3 have a larger heat dissipation area, facilitating heat dissipation of the driving structure 2. At the same time, wrapping the driving structure 2 by the arc surface 311 can also make the driving structure 2 more firmly fixed and can play a shock-absorbing effect on the driving structure 2. The flat surface 33 is exposed to the shell 1 so that the shell 1 as a whole is relatively flat, improving the aesthetic appearance.

[0043] Further, the flat surface 33 of the heat-conducting structure 3 exposed to the shell 1 comprises a first flat surface 331 facing the bottom wall 11 and a second flat surface 332 facing the side wall 12, the first flat surface 331 is exposed to the shell 1 through the first opening 141, and the second flat surface 332 is exposed to the shell 1 through the second opening 142. Actively dissipating heat from the driving structure 2 through the first flat surface 331 and the second flat surface 332 can improve the heat dissipation efficiency of the heat-conducting structure 3 and achieve the purpose of rapid heat dissipation.

[0044] Further, the flat surface 33 is flush with the flat surface 33 of the opening 14. Since the first opening 141 is arranged on the bottom wall 11 of the shell 1, if the first flat surface 331 of the heat-conducting structure 3 exposed to the first opening 141 is not flush with the flat surface 33 of the opening 14, the first flat surface 331 of the heat-conducting structure 3 will protrude out of the first opening 141 and be exposed to the outside of the shell 1, affecting the aesthetic appearance and smooth movement of the brush assembly 100. The second opening 142 is arranged on the inclined side wall 61 of the dirt suction channel 6, and if the second flat surface 332 is not flush with the flat surface 33 of the second opening 142, it will affect the blocking of garbage from entering the garbage can through the dirt suction channel 6, causing the garbage to fall on the surface to be cleaned, thereby affecting the cleaning effect of the cleaning device.

[0045] In the embodiment, the heat-conducting structure 3 comprises a first heat-conducting member 31 and a second heat-conducting member 32, the first heat-conducting member 31 and the second heat-conducting member 32 are arranged separately and stacked, and the first heat-conducting member 31 is arranged closer to the driving structure 2 than the second heat-conducting member 32. In other embodiments, the heat-conducting structure 3 can also be arranged integrally, or the heat-conducting structure 3 is one heat-conducting member. The present application does not limit this.

[0046] Further, the first heat-conducting member 31 is an insulating elastic heat-conducting member, and the second heat-conducting member 32 is a metal heat-conducting member. Preferably, the first heat-conducting member 31 is a heat-conducting silica gel, and the second heat-conducting member 32 is a heat-dissipating aluminum block. By setting the first heat-conducting member 31 as an insulating elastic heat-conducting member, the safety of the brush assembly 100 can be improved, and meanwhile, the elastic first heat-conducting member 31 can also play a damping effect on the driving structure 2, thereby prolonging the service life of the driving structure 2. By setting the second heat-conducting member 32 as a metal heat-conducting member, the heat dissipation efficiency can be improved, and the heat generated by the driving structure 2 can be transferred out more quickly.

[0047] Further, the second heat-conducting member 32 comprises a receiving portion 321 for receiving the first heat-conducting member 31, a first protruding portion 322 extending from the receiving portion 321 to the bottom wall 11 of the shell 1, and / or a second protruding portion 323 extending from the receiving portion 321 to the side wall 12 of the shell 1. The first protruding portion 322 is exposed to the bottom wall 11 of the shell 1 through a first opening 141 on the shell 1, and the second protruding portion 323 is exposed to the side wall 12 of the shell 1 through a second opening 142 on the shell 1.

[0048] In the embodiment, the receiving portion 321 comprises a top surface facing the first heat-conducting member 31 and a bottom surface facing away from the first heat-conducting member 31. The top surface is arc-shaped, and the shape thereof matches the shape of the first heat-conducting member 31, so as to increase the contact area and thereby increase the heat dissipation area. In addition, the arc-shaped receiving portion 321 can better wrap the first heat-conducting member 31, thereby playing a role of fixing and limiting the first heat-conducting member 31. The top surface and the bottom surface have a gap therebetween, so as to increase air convection and thereby increase the heat dissipation rate.

[0049] The first protruding portion 322 extends from the side of the receiving portion 321 facing away from the first heat-conducting member 31 to the direction of the bottom wall 11 of the shell 1. Preferably, the first protruding portion 322 has a step with the bottom of the receiving portion 321, so as to be clamped in the first opening 141. In the embodiment, the side surface of the first protruding portion 322 facing the surface to be cleaned is a first plane 331. By exposing the first protruding portion 322 to the shell 1, the driving structure 2 can be actively cooled, and meanwhile, the heat transferred to the surface to be cleaned through the first protruding portion 322 can also help to quickly dry the surface to be cleaned, thereby preventing water stains on the surface to be cleaned and improving the heat utilization rate.

[0050] The second protruding part 323 is arranged at the side of the accommodating part 321 and exposed to the dirt suction channel 6 through the second opening 142 arranged on the dirt suction channel 6. In the embodiment, the second protruding part 323 is a second plane 332 facing the side of the dirt suction channel 6. The second plane 332 is an inclined side surface matching the inclined side wall 61 of the dirt suction channel 6. That is, the second protruding part 323 is a wedge-shaped structure, the cross-sectional area of which gradually increases or decreases from one end to the other end, so that the second plane 332 exposed by the second protruding part 323 is flush with the plane 33 where the second opening 142 is located. By arranging the second protruding part 323 in the dirt suction channel 6, the heat on the driving structure 2 can be transferred into the dirt suction channel 6, so that the garbage on the surface to be cleaned can be heated through the dirt suction opening 5, thereby more conveniently sucking the fixed garbage into the dirt suction channel 6. In addition, the airflow generated by the air duct assembly 4 can also help the heat conduction structure 3 to dissipate heat, thereby accelerating the heat dissipation efficiency.

[0051] The application further provides a cleaning device (not shown) comprising the above-mentioned floor brush assembly 100. The cleaning device can be a combination of a mop and a vacuum cleaner, a floor mopping robot, and other cleaning devices with sweeping and mopping functions, and in particular, the cleaning device can be a handheld floor washing machine, and more particularly, a light-weight product such as a floor washing machine.

[0052] By arranging the heat conduction structure 3 to actively dissipate heat from the driving structure 2 of the floor washing machine, a high-power driving structure 2 can be arranged on the floor washing machine, thereby improving the working power of the floor washing machine and improving the cleaning effect. Due to the presence of the heat conduction structure 3, the driving structure 2 can be actively cooled, prolonging the service life of the driving structure 2, and improving the problem of high temperature in the floor brush shell material, which can cause burns to people, thereby meeting the user's pursuit of light use while obtaining higher performance product use experience.

[0053] In summary, the floor brush assembly 100 of the application sets the heat conduction structure 3 between the driving structure 2 and the shell 1, and the heat conduction structure 3 is at least partially in contact with the driving structure 2 and at least partially exposed to the shell 1 through the opening 14, so as to actively dissipate heat from the driving structure 2 through the heat conduction structure 3, thereby improving the service life of the floor brush assembly 100. In particular, when the opening 14 is arranged on the bottom wall 11 of the shell 1 facing the surface to be cleaned, one end of the heat conduction structure 3 is in direct contact with the driving structure 2, and the other end is exposed to the shell 1 through the opening 14 and in contact with the surface to be cleaned, so that the heat on the driving structure 2 can be transferred to the surface to be cleaned through the contact heat dissipation, not only actively dissipating heat from the driving structure 2, but also the heat transferred to the surface to be cleaned can help to quickly dry the surface to be cleaned, prevent the surface to be cleaned from having water stains, and improve the heat utilization rate.

[0054] The above examples are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced, without departing from the spirit and scope of the present application.
