[0001] This application relates to the field of cleaning technology, and more particularly, to a cleaning device. Background Art

[0002] Rotating brushes are used in cleaning machines such as floor sweeping robots, floor washing machines, and carpet cleaning machines. The rotating brushes used in existing competing products are all in the form of parallel contact with the ground. The rotating brushes in the parallel contact with the ground form have a large contact area with the ground and a large frictional resistance. Limited by the current of the motor driving the rotation of the rotating brush, the pressure applied by the rotating brush per unit area on the surface to be cleaned is limited, which limits the cleaning power of the rotating brush. Secondly, when the cleaning machine needs to clean the mop on the rotating brush, it needs to return to the base station for cleaning, and the cleaning operation of the mop cannot be completed during the cleaning process, which reduces the cleaning efficiency of the rotating brush and the cleaning effect on the surface to be cleaned.

[0003] It can be seen that the rotating brush on the existing cleaning machine has insufficient cleaning power and cannot complete the cleaning operation of the mop during the cleaning process, making it difficult to clean stubborn stains. Utility Model Content

[0038] Aiming at the problems that the cleaning power of the rotary brush on the existing cleaning machine is insufficient and the mop cannot be cleaned during the cleaning process, the first embodiment of the present utility model provides a cleaning device. Please refer to Figures 1 to 5, the cleaning device includes a main body 10, a cleaning mechanism, and a cleaning tray 40. Among them, the cleaning mechanism includes a driving component 20 and a cleaning component 30. The driving component 20 is arranged inside the main body 10, and the cleaning component 30 is connected to the driving component 20. The cleaning component 30 is inclined to the surface to be cleaned. The driving component 20 drives the cleaning component 30 to rotate, so that the cleaning component 30 can complete the cleaning work on the surface to be cleaned during the rotation process. Since the cleaning component 30 during the rotary cleaning work will be inclined to the surface to be cleaned, the ground area of the cleaning component 30 can be reduced, the cleaning strength on the surface to be cleaned can be improved, and the cleaning component 30 can efficiently remove stubborn stains. The cleaning tray 40 is connected to the main body 10, and a cleaning chamber is formed by surrounding between the cleaning tray 40 and the main body 10. The assembly between the cleaning tray 40 and the main body 10 is efficient and convenient. After the cleaning chamber is formed between the cleaning tray 40 and the main body 10, at least part of the cleaning component 30 is located in the cleaning chamber, and the cleaning component 30 can be cleaned through the cleaning tray 40. Therefore, the cleaning device can achieve self-cleaning through the cleaning tray 40 during the cleaning work of the cleaning component 30 without reciprocating back to the base station, improving the cleaning efficiency of the cleaning component 30 and the cleaning effect on the surface to be cleaned (such as the ground, table, wall, etc.).

[0039] It can be seen that the cleaning mechanism of the cleaning device provided in this embodiment includes a driving component 20 and a cleaning component 30. The driving component 20 is arranged inside the main body 10 of the cleaning device, the cleaning component 30 is connected to the driving component 20, the cleaning component 30 is inclined to the surface to be cleaned, and the driving component 20 drives the cleaning component 30 to rotate to clean the surface to be cleaned. During the cleaning process, since the cleaning component 30 is inclined to the surface to be cleaned (such as the ground, tabletop, wall surface, etc.), the ground area of the cleaning component 30 can be reduced to increase the pressure exerted by the cleaning component 30 per unit area on the surface to be cleaned, greatly improving the cleaning strength of the cleaning component 30 and achieving the smooth removal of stubborn stains. Secondly, a cleaning tray 40 is connected to the main body 10 of the cleaning device, and a cleaning chamber is formed by surrounding between the cleaning tray 40 and the main body 10. During the process of the cleaning component 30 rotating to perform the cleaning work, each part of the cleaning component 30 will continuously rotate into the cleaning chamber for self-cleaning. Therefore, the cleaning device can complete the cleaning operation of the cleaning component 30 during the cleaning process without returning to the base station, improving the cleaning efficiency of the cleaning component 30 and the cleaning effect and cleaning ability on the surface to be cleaned, making the surface to be cleaned cleaner and tidier.

[0040] As Figure 4 shown, the cleaning component 30 in this embodiment includes a support plate 31 and a flexible cleaning member 32. The support plate 31 is connected to the driving component 20 to rotate under the drive of the driving component 20. The side of the support plate 31 away from the main body 10 forms a first included angle with the surface to be cleaned (the first included angle is Figure 4The angle indicated by the symbol α), the flexible cleaning member 32 is laid on the side of the support plate 31 away from the main body 10, and the flexible cleaning member 32 can be inclined with respect to the surface to be cleaned under the support of the support plate 31. During the process of the support plate 31 driving the flexible cleaning member 32 to rotate and clean, the support plate 31 can apply a relatively large cleaning force to the surface to be cleaned through the flexible cleaning member 32, thereby improving the cleaning effect on the surface to be cleaned. Among them, the flexible cleaning member 32 has a cleaning portion 321 away from the support plate 31. Along the direction parallel to the support plate 31, the cross-section of the cleaning portion 321 gradually decreases in the direction away from the support plate 31. Thus, while the support plate 31 applies a relatively large cleaning force to the surface to be cleaned through the flexible cleaning member 32, due to the gradual decrease in the cross-section of the cleaning portion 321, at least a part of the surface of the cleaning portion 321 away from the support plate 31 can contact the surface to be cleaned, increasing the cleaning area of the cleaning portion 321 on the surface to be cleaned, and further improving the cleaning efficiency of the inclined cleaning assembly 30.

[0041] It can be seen that this embodiment can achieve cleaning the surface to be cleaned through a relatively large cleaning area and cleaning force, making the cleaning efficiency and cleaning effect of the inclined cleaning assembly 30 both higher, and the cleaning efficiency is not lower than that of a flat rotary brush in contact with the ground. Along the direction away from the support plate 31, the cleaning portion 321 of the flexible cleaning member 32 has a certain thickness, so that when the cross-section of the cleaning portion 321 gradually decreases in the direction away from the support plate 31, the contact area between the surface of the cleaning portion 321 and the surface to be cleaned can be increased, realizing efficient cleaning of the surface to be cleaned. The flexible cleaning member 32 in this embodiment can be a mop, a rubber brush, a sponge brush, etc. When the flexible cleaning member 32 is a mop, the cleaning portion 321 is the part of the mop away from the support plate 31, so as to contact the surface to be cleaned through the cleaning portion 321 of the mop, improving the cleaning efficiency of the cleaning device provided in this embodiment.

[0042] Along the direction parallel to the support plate 31, the cross-section of the cleaning portion 321 is circular. Thus, during the process of the support plate 31 driving the flexible cleaning member 32 to rotate, the frictional resistance between the cleaning portion 321 and the surface to be cleaned can be reduced, enabling the cleaning portion 321 of the flexible cleaning member 32 to rotate quickly to achieve efficient cleaning of the surface to be cleaned. As Figure 3 and Figure 5 shown, along the direction perpendicular to the support plate 31, the cross-section of the cleaning portion 321 is an isosceles trapezoid. That is to say, the cleaning portion 321 is an overall cylindrical structure with a gradually decreasing cross-section. Since the cross-section of the cleaning portion 321 is an isosceles trapezoid, during the process of the cleaning portion 321 rotating with the flexible cleaning member 32, there is a relatively large contact area between each part of the outer peripheral surface of the cleaning portion 321 and the surface to be cleaned, and the contact areas are all the same, resulting in higher cleaning efficiency.

[0043] When the cleaning assembly 30 in this embodiment is tilted, the first angle between the support plate 31 of the cleaning assembly 30 and the ground is greater than 0° and less than 45°, so as to ensure that a relatively large cleaning force can be applied to the flexible cleaning member 32 in the tilted state. The first angle may specifically include one of 3°, 4°, 5°, 8°, 13°, 15°, 20°, 24°, 26°, 28°, 30°, 32°, 35°, 37°, 38°, 40°, 41°, 43°, 45°, etc. Considering the spatial layout and cleaning effect of the cleaning device body 10 comprehensively, the preferred angle of the first angle in this embodiment is 5°. That is to say, when the first angle is 5°, it can not only ensure that the cleaning assembly 30 has a relatively large cleaning force and good cleaning effect, but also does not increase the volume of the body 10, reducing the processing difficulty and cost of the cleaning device body 10.

[0044] Specifically, as Figure 2 shown, a cleaning groove 41 is provided on one side of the cleaning tray 40 close to the body 10, and a cleaning chamber is formed by surrounding between the cleaning groove 41 and the body 10. It can be seen that in this embodiment, by connecting the cleaning tray 40 to the body 10, a cleaning chamber for cleaning the cleaning assembly 30 can be obtained, and the assembly is efficient and convenient. And an opening 42 for the cleaning assembly 30 to pass through is provided on one side of the cleaning groove 41 close to the cleaning assembly 30. During the process of the driving assembly 20 driving the cleaning assembly 30 to rotate, the cleaning assembly 30 can pass through the opening 42 into the cleaning chamber for cleaning, and the part of the cleaning assembly 30 located outside the cleaning chamber is responsible for cleaning the surface to be cleaned, realizing the purpose of cleaning the flexible cleaning member 32 while cleaning the surface to be cleaned. Compared with the existing method of cleaning the flexible cleaning member 32 at the base station and then returning to clean the surface to be cleaned, the cleaning efficiency is higher. Since the flexible cleaning member 32 always remains in a relatively clean state during the cleaning process, the cleaning effect of the flexible cleaning member 32 on the surface to be cleaned is also better.

[0045] In some embodiments of the present utility model, as Figure 1 shown, the body 10 may include a main body portion 11, a mounting portion 12, and a holding portion 13. The main body portion 11 is connected to the holding portion 13 through the mounting portion 12, and a mounting cavity is provided inside the main body portion 11. The driving assembly 20 may include a driving portion and a rotating shaft 23. The driving portion is arranged in the mounting cavity, one end of the rotating shaft 23 is connected to the driving portion, and the other end extends out of the end of the main body portion 11 away from the holding portion 13 to be connected to the cleaning assembly 30. The driving portion drives the rotating shaft 23 to drive the cleaning assembly 30 to rotate. When the rotating shaft 23 is connected to the support plate 31 of the cleaning assembly 30, it is perpendicular to the support plate 31 to drive the support plate 31 to rotate. Among them, the end surface of the main body portion 11 away from the holding portion 13 and the cleaning groove 41 of the cleaning tray 40 can surround and form a cleaning chamber, so that the cleaning assembly 30 can continuously enter the cleaning chamber for cleaning during the rotation process, improving the cleanliness of the cleaning assembly 30 during the cleaning process, and further improving the cleaning effect on the surface to be cleaned.

[0046] As mentioned in the foregoing of this embodiment, considering the overall spatial layout and cleaning effect of the cleaning device body 10, the preferred angle of the first included angle in this embodiment is 5°. When the angle of the first included angle is relatively large, such as one of 20°, 24°, 26°, 28°, 30°, 32°, 35°, 37°, 38°, 40°, 41°, 43°, 45°, etc. Since the driving part is mainly composed of the motor 21 and the gearbox 22, and the motor 21 and the gearbox 22 are relatively large in volume. If the driving part is installed obliquely in the body 10 to ensure that the cleaning component 30 can be tilted at a large angle, it will occupy a large installation cavity space, bringing certain difficulties to the design and installation of both the body 10 and the driving part. In this regard, in this embodiment, a transmission component can be arranged between the driving part and the cleaning component 30 to save the layout space occupied by the driving component 20 in the main body part 11. At this time, the rotating shaft 23 in this embodiment includes a first shaft section and a second shaft section. The first shaft section is located in the body 10 and is connected to the driving part. Specifically, the first shaft section is located in the installation cavity of the main body part 11 to be connected to the driving part. One end of the second shaft section located in the body 10 is in transmission connection with the first shaft section through a transmission component, and the first shaft section and the second shaft section form a second included angle. The other end of the second shaft section is located in the cleaning chamber and is connected to the support plate 31. The driving part drives the first shaft section to drive the second shaft section to rotate. Thus, in this embodiment, by splitting the relatively small-volume rotating shaft 23 into a first shaft section and a second shaft section, when the first shaft section and the second shaft section are in transmission connection through a transmission component and the first shaft section and the second shaft section form a second included angle, at this time, the installation angle of the driving component 20 in the main body part 11 can be kept at a relatively small angle, so as to enable the cleaning component 30 to be tilted at a large angle through the set second included angle. This avoids the additional production cost brought to the main body part 11 of the body 10 due to the over-large installation angle of the driving part, or the cost and inconvenience brought by redesigning the driving part to adapt to the space size of the installation cavity of the main body part 11. For example, when it is required that the first included angle of the cleaning component 30 is 24°, the driving part can still be kept at an installation angle of 5° or even less than 5° in the installation cavity, and the second included angle can be set as one of 19°, 20°, 21°, etc.

[0047] Among them, the transmission component may include a first bevel gear and a second bevel gear. The first bevel gear is connected to the end of the first shaft section far from the driving part, and the second bevel gear is connected to the end of the second shaft section far from the cleaning component 30 and meshes with the first bevel gear. In this embodiment, while realizing the transmission connection between the first shaft section and the second shaft section through the first bevel gear and the second bevel gear, by using the meshing relationship between the first bevel gear and the second bevel gear, the first shaft section and the second shaft section form a second included angle, which not only saves the space size of the installation cavity in the main body part 11, but also ensures that the cleaning component 30 has a large tilting angle driven by the second shaft section.

[0048] Please refer toFigures 6 to 8 , in this embodiment, a cleaning channel 43 is provided at the bottom of the cleaning chamber away from the main body 10. At least one of clear water, cleaning liquid, etc. can be introduced into the cleaning channel 43 to wet and clean the flexible cleaning member 32, so that the flexible cleaning member 32 always maintains good cleanliness, and the sewage and stains washed off are discharged through the cleaning channel 43. Along the width direction of the cleaning channel 43, the flexible cleaning member 32 is in interference fit with one side of the cleaning channel 43. Thus, during the rotation of the flexible cleaning member 32, the sewage, garbage impurities, etc. on the flexible cleaning member 32 can be scraped off and carried away by the cleaning channel 43, realizing self-cleaning of the cleaning assembly 30. Specifically, a water scraping part 430 can be provided on one side of the cleaning channel 43 to scrape the sewage, garbage impurities, etc. on the flexible cleaning member 32 into the cleaning channel 43 and wash them away through interference fit between the water scraping part 430 and the flexible cleaning member 32.

[0049] As Figure 6 shown, a first opening 44 and a second opening 45 are further provided on the cleaning tray 40. One end of the cleaning channel 43 is communicated with the first opening 44, and the other end is communicated with the second opening 45. The flexible cleaning member 32 is in interference fit with one side of the cleaning channel 43 close to the second opening 45. In this embodiment, clear water, cleaning liquid, etc. can be introduced into the cleaning channel 43 through the first opening 44, and the second opening 45 is used as a sewage extraction port to discharge the sewage, garbage impurities, etc. washed off from the flexible cleaning member 32 from the cleaning channel 43. Since the flexible cleaning member 32 is in interference fit with one side of the cleaning channel 43 close to the second opening 45, it can ensure that the sewage and stains are discharged from the second opening 45 in time, reduce the stains accumulated in the cleaning channel 43, and improve the cleaning effect on the cleaning assembly 30. For stubborn stains such as carbonized oil stains, the flexible cleaning member 32 can be cleaned by introducing hot water or cleaning liquid into the first opening 44, improving the cleaning effect on the flexible cleaning member 32.

[0050] A first boss 46 is further provided at the bottom of the cleaning chamber away from the main body 10 (i.e., the bottom of the cleaning tank 41). The first opening 44 and the second opening 45 are respectively located on opposite sides of the first boss 46. The length of the cleaning channel 43 extends from the first opening 44 to the second opening 45 along the outer periphery of the first boss 46. The flexible cleaning member 32 is in interference fit with one side of the cleaning channel 43 close to the first boss 46, so as to scrape the stains and sewage into the flow channel of the cleaning channel 43 close to the second opening 45 in time. Specifically, as Figure 6 shown, when the water scraping part 430 is located on at least one side of the cleaning channel 43 close to the second opening 45, the water scraping part 430 can be specifically arranged on the side of the first boss 46 close to the cleaning channel 43, which is convenient for scraping the stains and sewage into the cleaning channel 43 and discharging them from the second opening 45 in time.

[0051] As Figure 6As shown, a second boss 47 is further provided at the bottom of the cleaning chamber away from the main body 10. The second boss 47 protrudes from the surface of the first boss 46 and is located on one side of the first boss 46 where it is misaligned with the cleaning channel 43. The first opening 44 and the second opening 45 are spaced apart on the second boss 47, reducing the processing difficulty of the cleaning tray 40. Specifically, the cleaning tray 40 can be connected to the installation part 12 of the cleaning device through the second boss 47. At this time, a liquid inlet channel communicating with the first opening 44 and a sewage extraction channel communicating with the second opening 45 are provided in the installation part 12. During installation, the first opening 44 and the second opening 45 on the second boss 47 are respectively arranged corresponding to the liquid inlet channel and the sewage extraction channel. Clear water and cleaning liquid can be transmitted along the liquid inlet channel in the installation part 12 to the first opening 44 and enter the cleaning channel 43, and stains and sewage can be extracted along the sewage extraction channel from the second opening 45 through the sewage extraction channel.

[0052] The cleaning channel 43 in this embodiment includes a first channel section 431 and a second channel section 432. The second channel section 432 is closer to the second opening 45 than the first channel section 431 and communicates with the second opening 45. Along the rotation direction of the cleaning assembly 30, the width of the second channel section 432 is greater than the width of the first channel section 431, so that stains and sewage can quickly pass through the second opening 45 from the second channel section 432, preventing stains from accumulating in the first channel section 431 or the second channel section 432. The water scraping part 430 is specifically arranged on one side of the first boss 46 close to the second channel section 432, so as to scrape stains and sewage into the second channel section 432 and discharge them from the second opening 45 in time, preventing stains from accumulating in the cleaning channel 43.

[0053] The width of the second channel section 432 along the rotation direction of the cleaning assembly 30 gradually increases in the direction close to the second opening 45, so that stains can be quickly washed to the second channel section 432 and discharged from the second opening 45 along the second channel section 432. There is a first distance between the bottom of the first channel section 431 and the vertex of the first boss 46, and a second distance between the bottom of the second channel section 432 and the vertex of the first boss 46. The first distance is less than the second distance. That is, the highest water level of the cleaning channel 43 is in the first channel section 431, and the lowest water level is in the second channel section 432, so as to ensure that clear water, cleaning liquid, etc. can flow from the first channel section 431 with the highest water level to the second channel section 432, realizing the efficient cleaning of the cleaning assembly 30 while ensuring that stains and sewage are discharged from the second channel section 432.

[0054] The cleaning tray 40 provided in this embodiment can specifically be Figure 6 the structure with only one second opening 45 as shown, and the cleaning tray 40 can also be Figure 7 、 Figure 8The structure with two second openings 45 as shown. When there are two second openings 45 in the cleaning tray 40, the sewage pumping work can be carried out simultaneously through the two second openings 45, improving the sewage pumping efficiency and further enhancing the cleaning effect of the cleaning tray 40 on the cleaning component 30. Among them, the first opening 44 and the two second openings 45 are both arranged on the second boss 47, and the first opening 44 is located between the two second openings 45. The first flow channel section 431 is arranged on the first boss 46 and communicates with the first opening 44. The second flow channel section 432 extends along the outer periphery of the first boss 46 from one second opening 45 to the other second opening 45. The positions of both ends of the second flow channel section 432 close to the second opening 45 are the lowest water levels of the cleaning flow channel 43, and the highest water level is located in the first flow channel section 431. The distance from the bottom of the first flow channel section 431 to the vertex of the first boss 46 can gradually increase in the direction away from the first opening 44, so that clear water, cleaning liquid, etc. can better flow into the second flow channel section 432. The water scraping part 430 can be arranged on one side of the second flow channel section 432 away from the first boss 46 and close to one of the second openings 45 (as Figure 7 shown), and the cleaning component 30 first rotates to the end of the second flow channel section 432 where the water scraping part 430 is not arranged and then rotates to the end of the second flow channel section 432 where the water scraping part 430 is arranged for water scraping, facilitating scraping the sewage and stains into the second flow channel section 432.

[0055] When the cleaning tray 40 is the Figure 7 and Figure 8 structure as shown, the first flow channel section 431 arranged on the first boss 46 divides the first boss 46 into a first tabletop 461 and a second tabletop 462. Both the first tabletop 461 and the second tabletop 462 are inclined towards the direction close to the bottom of the second flow channel section 432, so that the clear water, cleaning liquid, etc. overflowing from the first flow channel section 431 can enter the second flow channel section 432 along the first tabletop 461 and the second tabletop 462, clean the first tabletop 461 and the second tabletop 462, and then timely discharge the sewage washed down along the second flow channel section 432 through the corresponding two second openings 45.

[0056] The flexible cleaning member 32 is in interference fit with the cleaning chamber to seal the cleaning flow channel 43. After the cleaning flow channel 43 is sealed, the cleaning device can be used perpendicular to the surface to be cleaned. When cleaning vertical surfaces such as walls, the clear water or sewage in the cleaning flow channel 43 is not likely to overflow, which is convenient to use and provides a good user experience. When the flexible cleaning member 32 is a mop, the cleaning chamber is fitted with a mop with an appropriate interference amount to prevent the clear water or sewage in the cleaning flow channel 43 from overflowing. In this embodiment, the flexible cleaning member 32 is provided with an avoidance hole 322 to reduce the frictional resistance between the flexible cleaning member 32 and the cleaning chamber through the avoidance hole 322, ensuring that the flexible cleaning member 32 can rotate smoothly for cleaning and self-cleaning. The avoidance hole 322 can penetrate or not penetrate the flexible cleaning member 32 along the direction close to the support plate 31, as long as the frictional force between the flexible cleaning member 32 and the cleaning chamber can be reduced. In this regard, this embodiment does not make a unique limitation here.

[0057] It can be seen that in this embodiment, while making the flexible cleaning member 32 and the cleaning chamber have a large interference amount to seal the cleaning flow channel 43, the frictional force between the flexible cleaning member 32 and the cleaning tray is reduced through the avoidance hole 322, improving the self-cleaning efficiency of the flexible cleaning member 32 and the cleaning efficiency and effect of cleaning the surface to be cleaned. The avoidance hole 322 can be specifically arranged in the middle of the flexible cleaning member 32 so that at least part of the outer peripheral surface of the cleaning part 321 of the flexible cleaning member 32 can contact the surface to be cleaned, improving the cleaning efficiency.

[0058] In this embodiment, by tilting the cleaning assembly 30 (commonly known as a rotary brush) with respect to the ground, the contact area of the cleaning assembly 30 with the ground is reduced, greatly improving the cleaning force of the cleaning assembly 30. At the same time, by designing the flexible cleaning member 32 with a trapezoidal cross-sectional structure, the cleaning efficiency of the tilted cleaning assembly 30 is not lower than that of a planar rotary brush. In addition, through the provided cleaning tray 40, the self-cleaning requirement of the cleaning assembly 30 is met, enhancing the cleaning ability.

[0059] The second embodiment of the present utility model provides a base station, which includes a cleaning device. For the specific structure of the cleaning device, please refer to the content provided in the first embodiment of the present utility model, and this embodiment will not be elaborated here.

[0060] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations of the spatial relative descriptions used herein will be made accordingly.

[0061] In addition, it should be noted that the use of terms such as "first" and "second" to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present application.

[0062] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various modifications and variations can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
