The present disclosure provides a cleaning apparatus, which may be a cleaning apparatus known to those skilled in the art, such as a sweeping robot, a floor washing robot, a hand-held floor washing machine, and the like, and which includes a body provided with a driving device and a cleaning device for cleaning a working surface. The driving device is in transmission connection with the cleaning device, and the cleaning device is configured to rotate relative to the machine body under the driving of the driving device.

Specifically, an inner cavity is arranged in the cleaning device, one end of the driving device is fixedly connected to the machine body, and the other end of the driving device extends into the inner cavity of the cleaning device and is in transmission connection with the cleaning device, so that the cleaning device is driven to rotate.

In addition, a waterway channel is arranged on the cleaning device, and the waterway channel is constructed to be flowed through by water. The water in the waterway channel exchanges heat with the temperature difference between the driving device so as to realize the heat dissipation of the driving device in the process of flowing the water.

The waterway channel is used for supplying water to the cleaning device so as to attach water to the working surface for cleaning. For example, in one embodiment of the present disclosure, the cleaning device is a cleaning roller 3 rotatably connected to the machine body. When the cleaning device works, water is supplied to the cleaning roller 3 through the waterway channel so as to wet cleaning pieces such as rags and flocks on the cleaning roller 3, and therefore the cleaning roller 3 can clean a working surface in the rotating process. The waterway channel of the present disclosure extends to the position corresponding to the driving device on the cleaning device, which enables the driving device in the cleaning device to be cooled down while supplying water to the cleaning device.

For better understanding, the specific structure and the working principle of the cleaning device of the present disclosure are described in detail below by taking a handheld cleaning device as an example, in conjunction with fig. 1 to 7 of the drawings.

Example one

Referring to fig. 1, the cleaning apparatus of the present disclosure is a hand-held cleaning apparatus including a body, a floor brush assembly. The body is used for carrying various components of the cleaning device, such as a battery, a dust box, a sewage box, a clean water box and the like, which are well known to those skilled in the art, and the specific structure and components are determined according to the structure and function of the cleaning device, and the disclosure is not limited thereto.

The floor brush assembly is used for cleaning a work surface, and in some embodiments of the present disclosure, referring to fig. 2, the floor brush assembly includes a body 1, a driving device, and a cleaning device. The driving device is configured to be in transmission fit with the cleaning device so as to drive the cleaning device to rotate relative to the machine body 1. The driving device and the cleaning device may be engaged and engaged in a manner known to those skilled in the art, such as a bevel gear connection, and will not be described herein in detail.

In some embodiments of the present disclosure, referring to fig. 4, the cleaning device has a hollow lumen 31 extending through opposite ends of the cleaning device, which are respectively identified as a first end 33 and a second end 34. Specifically, one end of the driving device is connected to the machine body 1, and the other end of the driving device extends into the inner cavity 31 of the cleaning device from the first end 33 of the cleaning device and is in transmission fit with the cleaning device.

The cleaning device of the present disclosure may employ a structure having a cleaning function, such as a wiper structure, which is well known to those skilled in the art, and the axis of rotation of which is perpendicular to the cleaning surface, so that the cleaning surface, such as the floor, can be cleaned while rotating along its own axis. Of course, the cleaning device may take other configurations than a wiper structure, as would be apparent to those skilled in the art. In some embodiments of the disclosure, cleaning cotton, bristles, rags, or other cleaning elements are disposed on the outer surface of the cleaning device. In one embodiment of the present disclosure, the cleaning device may be a cleaning cylinder 3 having a cylindrical shape, and the rotation axis of the cleaning cylinder 3 is parallel to the working surface and configured to rotate relative to the machine body 1, thereby cleaning the surface to be cleaned.

The driving device can be a motor component 2, and the motor component 2 can comprise a motor shell and a motor cover sleeved outside the motor shell. Of course, it is obvious to those skilled in the art that the motor assembly 2 further includes a stator and a rotor disposed in the motor housing, and detailed description thereof is omitted here.

In one embodiment of the present disclosure, a water channel 32 is disposed on the cleaning drum 3, and the water channel 32 is configured to allow water to flow therethrough to dissipate heat of the motor assembly 2 in the inner cavity 31 of the cleaning drum 3. Referring to fig. 6, the waterway channel 32 is configured to extend on the side wall of the cleaning drum 3, and is configured to extend to an area overlapping with at least a part of the motor assembly 2. This is because motor element 2 is at the during operation, and the heat that it gived off can concentrate on cleaning roller 3 with the region that motor element 2 corresponds, consequently makes liquid flow to the position that corresponds with motor element 2 along waterway 32, can cool down to the corresponding region on cleaning roller 3 to reach the radiating effect of motor element 2.

In some embodiments of the present disclosure, referring to fig. 6, the cleaning drum 3 includes an inner drum 35 and an outer drum 36 sleeved outside the inner drum 35, the waterway channel 32 includes a flow channel 321 extending along the axial direction of the cleaning device, and the flow channel 321 is disposed between the inner drum 35 and the outer drum 36.

In another embodiment of the present disclosure, with continued reference to fig. 6, grooves are provided on the inner wall of the cleaning drum 3. The plurality of grooves disposed at different angles cooperate to form a flow passage 321 for water to flow through. Specifically, the flow path 321 includes a groove provided on the outer wall of the inner drum 35, and the inner wall of the outer drum 36 and the groove of the inner drum 35 enclose the flow path 321.

In another embodiment of the present disclosure, the flow path 321 includes a groove provided on an inner wall of the outer drum 36, and the outer wall of the inner drum 35 and the groove of the outer drum 36 enclose the flow path 321.

In some embodiments of the present disclosure, the waterway channel 32 is configured to extend on an outer wall of the inner drum 35 of the cleaning drum 3, and is configured to extend to an area overlapping with at least a portion of the motor assembly 2. Referring to fig. 4, when there is an overlapping region between the water path channel 32 and the motor assembly 2, water in the water path channel 32 may flow to a region where the motor assembly 2 is located, and at this time, a heat dissipation effect of performing heat exchange based on a temperature difference between the two is the best.

In addition, by adjusting the overlapping area of the waterway channel 32 and the motor assembly 2, the time for the liquid to flow through the area corresponding to the motor assembly 2 can be prolonged, thereby controlling the temperature of the inner cavity of the cleaning roller 3 by controlling the time of heat exchange.

In some embodiments of the present disclosure, the waterway channel 32 further includes a water outlet 322 communicating with the flow channel 321 and radially penetrating to the outside of the cleaning drum 3. In actual use, the water in the flow channel 321 is configured to be discharged through the water outlet 322, and the discharged water is used for wetting the outer surface of the cleaning drum 3. In practical application, cleaning pieces such as cleaning cloth, brush hairs and flocking hairs which are used for being in contact with the working surface are further arranged outside the cleaning roller 3, and the cleaning pieces can be soaked by water discharged from the water outlet 322 so as to be cleaned by attaching water to the working surface. In addition, the water in the water flowing through the water passage 32 can be continuously cooled for the driving motor 2.

In some embodiments of the present disclosure, with continued reference to fig. 6, the outer drum 36 of the cleaning drum 3 is provided with a plurality of water outlets 322. Specifically, the water outlets 322 are configured to be uniformly distributed in sequence along the axial direction of the cleaning drum 3, so that the moisture in the water path channel 32 can uniformly wet the outer surface of the cleaning drum 3. In a specific embodiment of the present disclosure, referring to fig. 6, eight water outlets 322 are provided on the outer wall of the cleaning roller 3, and the eight water outlets 322 are sequentially arranged along the axial direction of the cleaning roller 3.

In some embodiments of the present disclosure, referring to fig. 6, the waterway channel 32 further has an inlet end 323, and the inlet end 323 is configured to introduce water from the outside into the waterway channel 32.

It should be noted that, when the cleaning roller 3 is provided with a plurality of water outlets 322, the flow distance between the inlet 323 and each water outlet 322 is equal. The moisture thus flowing from the inlet port 323 to the waterway channel 32 can flow to the outlet port 322 at a close timing and flow rate. So that the water outlet amount at each water outlet can be averaged, and the outer wall of the cleaning roller 3 can be uniformly wetted.

In some embodiments of the present disclosure, referring to fig. 6, the flow passage 321 includes a straight flow passage 321a, a return flow passage 321b, and a dispersion passage 321c, which are sequentially communicated.

Specifically, the straight flow passage 321a is configured to extend to a position adjacent to the first end 33 of the cleaning roller 3 at the inlet end 323 on the cleaning roller 3, thus achieving the maximum increase in the overlapping area between the two in the axial direction of the cleaning roller 3.

The return passage 321b is configured to extend from a position corresponding to the straight passage 321a to a middle position of the cleaning drum 3. The area of the overlapping area between the water channel 32 and the motor assembly 2 is increased by arranging the return channel 321b, so that the time for the heat exchange between the flow channel 321 and the inner cavity 31 of the cleaning roller 3 is prolonged, and the cooling effect is enhanced.

The water outlet 322 of the water path passage 32 is configured to communicate with the return passage 321b through the dispersion passage 321c. While increasing the overlapping area of the waterway channel 32 and the motor assembly 2, it is ensured that the water inside the waterway channel 32 can flow out of the cleaning drum 3 from the water outlet 322 to complete the water circulation in the whole waterway channel 32.

In the present embodiment, the direct current channel 321a, the return channel 321b, and the dispersing channel 321c are arranged to have more overlapping areas with the motor assembly 2, so as to prolong the heat exchange time and enhance the cooling effect.

In a specific embodiment of the present disclosure, the water flowing in the flow passage 321 may be clean water. The liquid in the flow path 321 may also be a liquid containing a cleaning agent, or a liquid formulated with other additives, which can be adjusted to different cleaning compositions to impart different cleaning functions to the cleaning roller 3.

In some embodiments of the present disclosure, referring to fig. 4 and 6, a rotation cavity 341 is provided at an end surface position of the second end 34 of the inner drum 35, i.e., an end far from the motor assembly 2. Specifically, in the present embodiment, the inlet end 323 of the waterway channel 32 is configured to extend radially inward from a position between the inner drum 35 and the outer drum 36 and to penetrate the rotating chamber 341. The body 1 is provided with a water inlet portion 11 rotatably engaged with the rotating chamber 341, and external liquid is configured to flow to the inlet end 323 through the water inlet portion 11.

In some embodiments of the present disclosure, referring to fig. 4, a sealing member is disposed between the water inlet portion 11 and the rotating chamber 341, and the sealing member is configured to dynamically seal a connection between the water inlet portion 11 and the cleaning drum 3 during the rotation of the water inlet portion 11 relative to the cleaning drum 3, so as to avoid a water leakage condition in this region.

In some embodiments of the present disclosure, referring to fig. 4 and 6, the water inlet portion 11 includes a first water inlet channel 111 extending axially, and a second water inlet channel 112 communicating with the first water inlet channel 111 and radially penetrating through a sidewall of the water inlet portion 11. The external water flows through the first water inlet passage 111 toward the second water inlet passage 112 and finally flows into the water passage 32 through the inlet end 323.

In one embodiment of the present disclosure, a plurality of water passage channels 32 are provided on the outer wall of the cleaning drum 3. The plurality of water path channels 32 are configured to be uniformly distributed along the circumferential direction of the cleaning drum 3, so that the overlapping area between the water path channels 32 and the motor assembly 2 can be maximally increased. Specifically, six waterway channels 32 are provided in the present embodiment. Each waterway channel 32 extends along the axial direction of the cleaning drum 3, and six waterway channels 32 are sequentially distributed in the circumferential direction of the cleaning drum 3, thereby providing rapid heat dissipation to the motor assembly 2.

Each of the waterway passages 32 is formed with an inlet port 323 at the rotating chamber 341, and six inlet ports 323 are sequentially distributed on the inner wall of the rotating chamber 341. In some embodiments of the present disclosure, the water inlet 11 is configured to rotate with respect to the cleaning drum 3, and sequentially communicates with the plurality of inlet ports 323 during the rotation. In actual use, when the cleaning drum 3 rotates to connect one of the inlet ends 323 with the second water inlet passage 112 of the water inlet portion 11, water is supplied to the corresponding water path passage 32 through the second water inlet passage 112. Thus, the water supplied from the water inlet 11 is uniformly supplied to the inside of each waterway channel 32 during the rotation.

Cleaning roller 3 when cleaning the working face, can adsorb the dirty absorption of working face on cleaning roller 3, see fig. 5, still has wiper blade 4 on the organism 1, and wiper blade 4 extends along cleaning roller 3's axial direction, and is constructed as the outer wall of extrusion cleaning roller 3 to scrape off the dirty on cleaning roller 3 outer wall. Referring to fig. 5 and 7, the cleaning cylinder 3 is in a rotating state during operation, and the cleaning cylinder 3 is configured to be supplied with water from the water inlet 11 through the corresponding inlet port 323 after passing through the wiper plate 4 in advance.

Typically, the cleaning roller 3 rotates about its own axis under the control of the motor assembly 2. The wiper blade 4 is usually disposed at a rear position of the cleaning cylinder 3. For example, when the cleaning roller 3 rotates counterclockwise, the cleaning roller 3 may rotate to engage with the wiper blade 4 to wipe off the dirt after passing the working surface and cleaning the working surface. At this time, the water inlet 11 supplies water to the cleaning cylinder 3 through the corresponding inlet 323 to supply water to the area of the cleaning cylinder 3 scraped by the wiper blade 4.

In some embodiments of the present disclosure, referring to fig. 4, in order to facilitate the installation and removal of the cleaning roller 3, the output end of the motor assembly 2 is provided with a coupling 21, and a transmission seat 22 is provided in the inner cavity 31 of the cleaning roller 3. The coupling 21 and the transmission seat 22 can be fitted together in a plug-in manner. In the actual use process, the motor assembly 2 can drive the transmission seat 22 to rotate through the coupling 21, so as to drive the cleaning roller 3 to rotate synchronously.

In an embodiment of the present disclosure, the heat dissipation air duct 23 is disposed in the motor assembly 2, when the motor assembly 2 works, the heat dissipation air duct 23 can suck air flow from the outside by using a principle of negative pressure, so as to dissipate heat of an internal structure of the motor assembly 2, the temperature of the outside air flow rises after the heat dissipation of the motor assembly 2, and the air flow with the raised temperature flows out from an outlet of the heat dissipation air duct 23 and enters the inner cavity 31 of the cleaning roller 3. Alternatively, the external air flow enters the inner cavity 31 of the cleaning roller 3, then enters the heat dissipation air duct 23 of the motor assembly 2, and finally is dissipated from the end of the motor assembly 2, which is not specifically described in this disclosure.

Specifically, the housing of the motor assembly 2 is provided with a plurality of communication holes 24 penetrating through the outer wall of the motor assembly 2, and the communication holes 24 are configured to communicate the heat dissipation air duct 23 of the motor assembly 2 with the inner cavity 31 of the cleaning roller 3. The communication hole 24 may be provided in plural, and the plural communication holes 24 are configured to be circumferentially arrayed in the circumferential direction of the motor assembly 2.

In another embodiment of the present disclosure, with continued reference to fig. 2, the communication holes 24 are densely distributed in the main heat generating area of the motor assembly 2. In this way, during actual use, as much hot air as possible inside the motor assembly 2 can flow into the inner cavity 31 of the cleaning drum 3 through the communication hole 24, and thus can be rapidly dissipated through the air flow passage and the water path passage to reduce the internal temperature of the motor assembly 2.

In addition, through set up a plurality of intercommunicating pores 24 on the motor cover, can accelerate the circulation between the inside of motor element 2 and the external air current to motor element 2's radiating rate has been accelerated to a certain extent.

In addition, when the hot air inside the motor assembly 2 flows to the inner cavity 31 of the cleaning drum 3, there is a temperature difference between the water in the waterway channel 32 on the cleaning drum and the inner cavity 31, and the inner cavity 31 of the cleaning drum 3 can be cooled by the water flowing in the waterway channel 32 based on the heat exchange principle. The water heated by the heat exchange flows along the water path 32 to the water outlet 322 to wet the outer surface of the cleaning roller 3, and the heated water further improves the cleaning effect of the cleaning roller 3.

Therefore, through heat exchange, not only is the inner cavity 31 of the cleaning roller 3 cooled, but also the cleaning performance of the cleaning roller 3 is improved by utilizing the moisture heated after heat exchange.

Example two

Wherein, the driving device is connected to the machine body 1; a cleaning device configured to rotate relative to the machine body 1 to clean a cleaning surface; the cleaning device has an inner cavity 31, and the driving device is configured to extend into the inner cavity 31 of the cleaning device and be in transmission fit with the cleaning device; a water passage 32 is provided on the cleaning device, and the water passage 32 is configured to allow water to flow therethrough to dissipate heat from the driving device in the cleaning device cavity 31.

In the using process, heat exchange is carried out through the temperature difference between the waterway channel 32 on the cleaning device and the driving device, so that the driving device is cooled, the driving device is in a high-temperature state for a long time during operation, the driving device is damaged, and the service life of the driving device is shortened.

The structure, connection relationship, positional relationship of each component in the cleaning device, and the process of transferring and detaching the components from the driving device are the same as those described in the first embodiment, and are not described in detail herein.

In addition, the clean water tank of the cleaning device supplies water to the cleaning device through the waterway channel so as to wet the cleaning device, and thus, the working surface can be wet-mopped.

During operation of the cleaning apparatus, the driving device may emit a large amount of heat during the driving of the cleaning device to rotate. When water flows in the waterway channel, heat exchange reaction can be carried out by utilizing the temperature difference between the water and the inner cavity of the cleaning device so as to realize heat dissipation of the driving device.
