Description

Technical Field

[0001] This invention relates to the field of cleaning appliance technology, and more particularly to a floor brush assembly and cleaning equipment. Background Technology

[0002] With the development of technology, more and more families are adopting smart cleaning equipment to assist with cleaning. These devices can automatically sweep, vacuum, mop, and wash floors, bringing great convenience and freeing people from heavy housework. In particular, cleaning products, such as floor scrubbers, are increasingly favored by users.

[0003] Floor scrubbers have rollers on their brush assembly that face the ground. A motor drives the rollers to rotate and clean the floor. During operation, the rollers often encounter resistance, such as friction from contact with the floor and resistance from interaction with the squeegee assembly. This increases the motor's power and internal current, resulting in increased heat generation and higher temperatures for the motor itself and surrounding components. In particular, when the motor is built into the roller, the heat accumulates and cannot dissipate. When the temperature reaches a certain limit, it reduces the motor's lifespan. Furthermore, high temperatures can cause plastic parts to deform, leading to machine malfunction.

[0004] In view of this, it is indeed necessary to provide a floor brush assembly and cleaning equipment to solve the above problems. Summary of the Invention

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0029] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0030] This invention provides a cleaning device (not shown), which includes a device body and a floor brush assembly 100. This cleaning device can be a vacuum and mop combo, a mopping robot, a floor scrubbing robot, a handheld cleaning device, or other cleaning devices well-known to those skilled in the art. For clarity, a handheld floor scrubber will be used as an example for detailed explanation below. However, this should not be considered a limitation.

[0031] The handheld floor scrubber includes a main body (not shown) and a floor brush assembly 100 disposed below the main body. The floor brush assembly 100 and the main body can be detachably connected or fixedly connected. A handle for user operation is provided on top of the main body, and a control unit can be located on the handle to control the start / stop and operating mode of the handheld floor scrubber. The main body may also include a power supply (e.g., a power source) for providing power to the handheld floor scrubber, a clean water tank for storing clean water, a wastewater tank for collecting wastewater, and a waste bin for collecting garbage. Specific structures and components may vary depending on the structure and function of the cleaning equipment, and are not limited herein.

[0032] The floor brush assembly 100 is used to clean a surface to be cleaned, such as a floor or wall. In some embodiments, the floor brush assembly 100 includes a floor brush housing 1, a cleaning component 2, a drive device 3, and a heat dissipation assembly 4 disposed on the floor brush housing 1. The cleaning component 2 rotates relative to the floor brush housing 1 to clean the surface to be cleaned. The drive device 3 is configured to drive the cleaning component 2 to provide rotational power for the cleaning component 2. The heat dissipation assembly 4 is configured to actively dissipate heat from the drive device 3 to prevent overheating and reduced service life, thus avoiding malfunctions. The drive device and the cleaning component 2 can be connected by means of snap-fit, gear connection, or other transmission connections well known to those skilled in the art, and will not be described in detail here.

[0033] Please see Figures 1 to 9 The image shows a preferred embodiment of the floor brush assembly 100 of the present invention. The floor brush assembly 100 includes a floor brush housing 1, a cleaning component 2, a driving device 3, and a heat dissipation component 4.

[0034] The floor brush housing 1 is detachably connected to the bottom of the device body. The floor brush housing 1 has a water channel (not shown) connected to the clean water tank inside the device body, and a suction channel 5 connected to the wastewater tank inside the device body. The water channel guides liquid from the clean water tank to the cleaning component 2, wetting it before cleaning the surface. A suction channel 6 is formed between the cleaning component 2 and the floor brush housing 1, and the suction channel 6 communicates with the suction channel 5. The cleaning component 2 transports solid and liquid debris from the ground through the suction channel 6 to the suction channel 5, and then through the suction channel 5 to the wastewater tank, thus completing the cleaning of the surface. Several casters (not shown) are provided on the side of the floor brush housing 1 facing the surface to be cleaned for easy movement and cleaning.

[0035] The floor brush housing 1 includes a main body 11 and a protrusion 12 extending from one side of the main body 11 away from the main body 11, the protrusion 12 for mounting a cleaning component 2. A mounting portion 121 for mounting the cleaning component 2 is provided on the protrusion 12, extending away from the protrusion 12. The cleaning component 2 is connected to the mounting portion 121. In this embodiment, the cleaning component 2 is detachably connected to the mounting portion 121 to facilitate cleaning of the cleaning component 2. In other embodiments, the cleaning component 2 may also be fixedly connected to the mounting portion 121, and this invention is not limited thereto.

[0036] The brush housing 1 also includes a brush cover 13, which is detachably connected to the main body 11 for easy removal and separate cleaning. The brush cover 13 is positioned above the cleaning component 2 and partially surrounds it, providing protection. The brush cover 13 and the main body 11 together form an installation space for the cleaning component. When the cleaning component 2 needs to be replaced, the brush cover 13 can be removed from the brush housing 1, replaced, and then reattached to the brush housing 1.

[0037] In some embodiments, the cleaning component 2 is detachably connected to the floor brush housing 1 and configured to rotate relative to the floor brush housing 1 to clean the surface to be cleaned. It should be understood that the cleaning component 2 of the present invention can employ a structure with cleaning function well known to those skilled in the art, such as a mop structure, where the rotation axis of the mop structure is perpendicular to the cleaning surface, allowing it to clean the surface, such as the floor, when rotating along its own axis. Of course, besides the mop structure, other structures can be used by those skilled in the art for the cleaning component 2. In some specific embodiments of the present invention, cleaning cotton, bristles, tufts, a cloth, or other cleaning components are provided on the outer surface of the cleaning component 2. In a preferred embodiment of the present invention (see...), Figures 1 to 7As shown, the cleaning component 2 can be a cylindrical cleaning roller 22. The rotation axis of the cleaning roller 22 is parallel to the surface to be cleaned and is configured to rotate relative to the floor brush housing 1, thereby cleaning the surface to be cleaned.

[0038] In this embodiment, the cleaning component 2 includes a connecting portion 21 connecting to the main body 11. The connecting portion 21 has a first latching portion 211, and the main body 11 has a corresponding second latching portion 111 on the side away from the protrusion 12. The cleaning component 2 is detachably connected to the floor brush housing 1 via the first latching portion 211 and the second latching portion 111. Preferably, one of the first latching portion 211 and the second latching portion 111 is a bayonet, and the other is a hook. In other embodiments, other detachable connection structures may also be used. Two parallel cleaning rollers 22 are provided on the connecting portion 21. The cleaning rollers 22 are configured to be driven by the driving device 3 to rotate relative to the surface to be cleaned, with their rotation axes parallel to the surface to be cleaned.

[0039] In some embodiments, the drive device 3 is provided, and two cleaning rollers 22 include a main roller and a driven roller. The main roller is driven by the drive device 3, and the driven roller has a transmission structure with the main roller, so that the driven roller can be driven by the main roller to rotate relative to the surface to be cleaned. In other embodiments, there may be two drive devices 3, which drive the two cleaning rollers 22 to rotate respectively. The rotation directions of the two cleaning rollers 22 may be the same or different, and the present invention is not limited thereto. In addition, it should be noted that in other embodiments, the number of cleaning rollers 22 is not limited to two; it may be one or more.

[0040] In some embodiments, the cleaning assembly 2 has an inner cavity 221. That is, the cleaning roller 22, which is driven by the drive device 3, has a hollow inner cavity 221 extending through its opposite ends. The inner cavity 221 is used to house the drive device 3, thereby saving installation space of the floor brush assembly 100, reducing the volume of the floor brush assembly 100, and promoting the miniaturization of the cleaning equipment.

[0041] The drive device 3 is located at least partially within the inner cavity 221 and is in drive engagement with the cleaning component 2 to provide power to the cleaning component 2.

[0042] The drive unit 3 includes a drive motor 31, which comprises a first end and a second section disposed opposite to each other. The first end is provided with a drive connector 32, which is used to drive the cleaning roller 22 to rotate. The second section is provided with a mounting member 33, which is used to connect the drive unit 3 to the floor brush housing 1. The drive motor 31 is arranged parallel to the cleaning roller 22 and extends along the axis of the cleaning roller 22. The first end extends into the inner cavity 221 of the cleaning roller 22 for drive connection. The mounting member 33 is at least partially exposed outside the inner cavity 221 of the cleaning roller 22 for connection with the floor brush housing 1.

[0043] Since the drive motor 31 is built into the inner cavity 221 of the cleaning roller 22, the drive motor 31 will generate heat when rotating at high speed. Overheating will damage the drive motor 31 or the cleaning roller 22. The heat generated by the drive motor 31 will accumulate between the outer shell of the drive motor 31 and the cleaning roller 22, that is, it will accumulate in the inner cavity 221 of the cleaning assembly 2. Therefore, a heat dissipation assembly 4 needs to be provided at the drive device 3 to actively dissipate heat from the drive device 3.

[0044] The heat dissipation component 4 is configured to actively dissipate heat from the drive device 3, preventing the heat generated by the drive device 3 from accumulating inside the cleaning component 2 and causing adverse effects on both the drive component and the cleaning component 2. The heat dissipation component 4 includes a first heat sink 41 and a second heat sink 42. The first heat sink 41 is disposed on the outside of the drive device 3 and in contact with its surface. The second heat sink 42 is disposed on the floor brush housing 1, located on the outside of the cleaning component 2, and is thermally connected to the first heat sink 41; the heat generated by the drive device 3 is transferred to the outside of the cleaning component 2 via the first heat sink 41 and the second heat sink 42. By placing the first heat sink 41 on the outside of the drive device 3 and in contact with its surface, and placing the second heat sink 42 on the outside of the cleaning assembly 2 and in heat transfer connection with the first heat sink 41, the heat generated by the drive device 3 can be transferred to the first heat sink 41 through direct contact. The first heat sink 41 then transfers the heat to the second heat sink 42, thereby transferring the heat generated by the drive device 3 located in the inner cavity 221 of the cleaning assembly 2 to the outside of the cleaning assembly 2. This actively dissipates heat from the drive device 3, reduces the temperature of the inner cavity 221 of the cleaning assembly 2, extends the service life of the drive device 3, and improves the performance of the drive device 3 and the floor brush assembly 100.

[0045] In some embodiments, the first heat sink 41 is a motor cover. The motor cover is made of a material that conducts heat easily, such as heat-dissipating metal. The motor cover wraps around the outside of the drive motor 31 and is in direct contact with the surface of the drive motor 31, so that the heat generated by the drive motor 31 can be transferred to the first heat sink 41.

[0046] Furthermore, the first heat sink 41 is also wrapped around the outer peripheral surface 331 of the mounting member 33, that is, the first heat sink 41 is in contact with the outer peripheral surface 331 of the mounting member 33, so that heat can be transferred from the first heat sink 41 to the mounting member 33.

[0047] A first fixing part 411 is provided on the first heat sink 41, and a second fixing part 3311 is provided on the outer peripheral surface 331 of the mounting part 33. The first heat sink 41 and the mounting part 33 are fixedly connected by the first fixing part 411 and the second fixing part 3311. In some embodiments, the first fixing part 411 and the second fixing part 3311 are fixing holes, through which fasteners such as bolts pass to fix the first heat sink 41 and the mounting part 33. At this time, the first heat sink 41 is in contact with the outer peripheral surface 331 of the mounting part 33.

[0048] The mounting component 33 also includes a mounting surface 332 facing the brush housing 1, the mounting surface 332 being connected to the brush housing 1, and a mounting portion 121 being provided on the protrusion 12 of the brush housing 1, the mounting component 33 being connected to the mounting portion 121.

[0049] The second heat sink 42 is disposed on the floor brush housing 1, located outside the cleaning assembly 2, and covers the mounting portion 121, located on the side of the mounting portion 121 facing the mounting member 33. Therefore, when the mounting member 33 is connected to the mounting portion 121, the mounting surface 332 of the mounting member 33 contacts and connects with the second heat sink 42, thereby the mounting member 33 can transfer heat to the second heat sink 42, and then to the outside of the cleaning assembly 2, realizing active heat dissipation of the drive device 3, reducing the temperature of the inner cavity 221 of the cleaning assembly 2, and extending the service life of the drive device 3 and the cleaning assembly 2.

[0050] In other words, in the above embodiments, the first heat sink 41 and the second heat sink 42 dissipate heat through contact with the mounting member 33. The heat generated by the driving device 3 is transferred to the mounting member 33 through the first heat sink 41, and then to the second heat sink 42 through the mounting member 33, so as to conduct the heat located in the inner cavity 221 of the cleaning component 2 to the outside of the cleaning component 2. In other embodiments, the first heat sink 41 may also be directly connected to the second heat sink 42. That is, the first heat sink 41 component includes the outer peripheral surface 331 of the mounting member 33, which at least covers the mounting surface 332 of the mounting member 33, thereby directly contacting the second heat sink 42. In this case, the heat generated by the driving device 3 can be directly transferred to the second heat sink 42 through the first heat sink 41. The present invention does not limit this.

[0051] Furthermore, since the outer peripheral surface 331 of the drive motor 31 and the mounting component 33 is wrapped by the first heat sink 41, and the mounting surface 332 of the mounting component 33 away from the drive motor 31 is in contact with the second heat sink 42 and sealed by the second heat sink 42, the drive motor 31 can be sealed in the inner cavity 221 of the cleaning roller 22 through the first heat sink 41 and the second heat sink 42, preventing water from entering the inner cavity 221 of the cleaning roller 22 and damaging the drive motor 31.

[0052] The second heat sink 42 includes a first portion 421 and a second portion 422 arranged at an angle. Preferably, the first portion 421 and the second portion 422 are integrally formed. The first portion 421 is disposed on the floor brush housing 1 and covers the mounting portion 121, while the second portion 422 is disposed on the outer side of the cleaning assembly 2 and extends radially along the cleaning assembly 2. This arrangement increases the area of ​​the second heat sink 42, thereby improving heat dissipation efficiency. Furthermore, since the second heat sink 42 is divided into the first portion 421 and the second portion 422 arranged at an angle, it is possible to dissipate the heat generated by the drive device 3 in different ways.

[0053] The first part 421 includes a first region 4211 built into the mounting part 121 and a second region 4212 exposed outside the mounting part 121. The first region 4211 has several mounting holes 4213 to facilitate the connection of the mounting component 33 of the drive device 3 to the brush housing 1. The second region 4212 is located outside the mounting part 121 and within the mounting space formed by the roller brush cover and the main body 11. A gap exists between the roller brush cover and the main body 11, allowing the second region 4212 to connect with the outside air for heat exchange. The second region 4212 has through holes to facilitate the connection of the brush cover 13 to the brush housing 1.

[0054] In some embodiments, the second portion 422 is disposed on the side of the main body 11 facing the installation space and extends along the axial direction of the cleaning roller 22. The second portion 422 is in contact with the outer surface of the cleaning assembly 2. The second portion 422 has an arcuate structure, and the curvature of the second portion 422 matches the curvature of the cleaning assembly 2. That is, the arcuate second portion 422 wraps around the cleaning roller 22, thereby allowing the second portion 422 to contact the cleaning roller 22. On the one hand, the second portion 422 can scrape off the debris adhering to the cleaning roller 22; on the other hand, the moisture on the cleaning roller 22 can absorb the heat of the second portion 422, thereby improving heat dissipation efficiency.

[0055] In some embodiments, the main body 11 is provided with a suction port 51, which communicates with the suction channel 5. A suction port 61 is formed between the two cleaning rollers 22, and / or a suction port 61 is formed between the cleaning component 2 and the floor brush housing 1, and a suction channel 6 is formed between the suction port 61 and the suction port 51, with the suction channel 5 and the suction channel 6 communicating with each other. A second portion 422 extends from the end of the first portion 421 into the suction channel 6. In this embodiment, the second portion 422 extends along the axial direction of the cleaning roller 22 and is located within the suction channel 6 formed between the suction port 61 formed between the cleaning component 2 and the floor brush housing 1 and the suction port 51. The exhaust assembly (not shown) of the cleaning device generates flowing air or wind within the suction channel 5 and the suction channel 6, which can carry away heat from the second portion 422, thereby improving heat dissipation efficiency. In addition, the suction channel 6 also contains some moisture absorbed from the ground, which can also carry away heat from the second portion 422, accelerating heat dissipation efficiency.

[0056] Optionally, one side of the second part 422 is wrapped around the outer surface of the cleaning roller 22, and the other side is located in the suction channel 6. In this case, the heat on the second part 422 can be dissipated by the moisture on the cleaning roller 22, or by the air or wind in the suction channel 6, or by the moisture, thereby improving the heat dissipation efficiency.

[0057] In some embodiments, the second heat sink 42 is integrally formed with the floor brush housing 1. In other embodiments, the second heat sink 42 and the floor brush housing 1 may also be separately configured and fixedly connected by assembly. The present invention does not limit this.

[0058] In this embodiment, the heat generated by the drive motor 31 is transferred from the first heat sink 41 to the mounting part 33, and then from the mounting part 33 to the first part 421 of the second heat sink 42, especially the first area 4211 of the first part 421. Since the second area 4212 is located outside the mounting part 121, it can circulate with the outside air, thereby dissipating heat from the first area 4211. Moreover, since the second heat sink 42 is integrally formed and made of a material that facilitates heat dissipation, the heat from the first area 4211 can also be transferred to the second part 422. Thus, the heat on the second part 422 can be dissipated through the moisture on the cleaning roller 22, or through the air or wind in the suction channel 6, or through the moisture. That is, the heat dissipation assembly 4 can conduct the heat located in the inner cavity 221 of the cleaning assembly 2 to the outside of the cleaning assembly 2, thereby actively dissipating heat from the drive device 3, reducing the temperature of the inner cavity 221 of the cleaning assembly 2, extending the service life of the drive device 3, and improving the performance of the drive device 3 and the floor brush assembly 100. Figure 3 and Figure 4 The arrows shown indicate the direction of heat transfer.

[0059] In summary, the floor brush assembly 100 of the present invention, by placing the first heat sink 41 on the outside of the drive device 3 and in contact with the surface of the drive device 3, and placing the second heat sink 42 on the outside of the cleaning assembly 2 and in heat transfer connection with the first heat sink 41, allows the heat generated by the drive device 3 to be directly transferred to the first heat sink 41, and the first heat sink 41 to transfer the heat to the second heat sink 42, thereby transferring the heat generated by the drive device 3 located in the inner cavity 221 of the cleaning assembly 2 to the outside of the cleaning assembly 2, so as to actively dissipate heat from the drive device 3, reduce the temperature of the inner cavity 221 of the cleaning assembly 2, extend the service life of the drive device 3, and improve the performance of the drive device 3 and the floor brush assembly 100.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
