Description

Cleaning equipment and cleaning system

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on September 26, 2023, with application number 202322626628.X and application name “A Cleaning Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of smart home, and in particular to a cleaning device and a cleaning system. Background Art

[0003] With the development of technology, household cleaning equipment has emerged. Among them, cleaning equipment that has the ability to absorb both dust and water has been favored by a large number of consumers.

[0004] During the cleaning process, the roller brush rotates at high speed, and most of the water droplets and dirt particles adhered to the fluff enter the sewage bucket through the sewage suction pipe. A small part will follow the roller brush into the next cycle, and a small part of the water droplets and dirt particles will be thrown out in the tangential direction of the roller brush under the high-speed rotation of the roller brush. The cover plate above the brush intercepts the thrown water droplets and dirt particles.

[0005] In order to automatically clean the dirt on the cover, the cover needs to be controlled to descend a certain distance so that the cover can be cleaned with a roller brush. However, the roller brush will wear out to a certain extent over time, resulting in reduced contact between the roller brush and the cover, which affects the cleaning effect of the cover.

DETAILED DESCRIPTION

[0032] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present application. However, it will be apparent to those skilled in the art that the present application can be implemented without one or more of these details. In other examples, some technical features well known in the art are not described in order to avoid confusion with the present application.

[0033] It should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, wholes, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0034] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of this application thorough and complete and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0035] As shown in Figure 1, an embodiment of the present application provides a cleaning device, including a floor brush module; the floor brush module includes a shell 3, a cleaning member 1, a cover plate 2 and a drive assembly 5, the cleaning member 1 and the drive assembly 5 are both arranged on the shell 3, the cover plate 2 is located above the cleaning member 1, and the cover plate 2 is connected to the drive assembly 5; the drive assembly 5 can drive the cover plate 2 to move toward or away from the cleaning member 1.

[0036] In addition to the above-mentioned components, the cleaning equipment may also include a driving motor for driving the cleaning element 1 to rotate, a liquid spraying assembly, a sewage suction port, and a sewage suction channel located inside the cleaning equipment and connected to the sewage suction port. The cleaning equipment can drive the cleaning element 1 to clean the dirty liquid and dirt on the ground through the driving motor, and absorb the dirty liquid and dirt on the ground through the sewage suction port. The absorbed dirty liquid and dirt enter the sewage suction channel through the sewage suction port.

[0037] The cover plate 2 is arranged above the cleaning member 1. When the cleaning equipment performs a cleaning operation, a small amount of dirty liquid and dirt on the cleaning member 1 is thrown out in the tangential direction of the cleaning member 1 under the high-speed rotation of the cleaning member 1. The cover plate 2 can intercept the dirty liquid and dirt thrown out by the cleaning member 1.

[0038] After the cleaning device completes its cleaning operation, or when a certain amount of dirty liquid and dirt accumulate on the cover plate 2, the cleaning member 1 is used to clean the dirty liquid and dirt on the cover plate 2. Specifically, the driving assembly 5 drives the cover plate 2 toward the roller brush 1 to increase the pressure of the cover plate 2 on the roller brush 1. In this way, regardless of how the size of the roller brush 1 changes, that is, even if the diameter of the roller brush 1 decreases due to long-term wear, the pressure applied by the cover plate 2 on the roller brush 1 can be maintained constant, thereby ensuring sufficient contact between the cover plate 2 and the roller brush 1, thereby improving the cleaning effect of the roller brush 1 on the cover plate 2.

[0039] Furthermore, the cleaning member 1 may be a roller brush, which interferes with the surface to be cleaned to achieve a cleaning operation on the surface to be cleaned. It is understandable that the cleaning member 1 may also be other cleaning elements.

[0040] Furthermore, a pressure detection portion 4 is provided on the housing 3 near the cover plate 2 .

[0041] Furthermore, the pressure detection unit 4 is configured to detect the pressure value applied by the cover plate 2 to the cleaning member 1 when cleaning the cover plate 2; the driving component 5 is configured to drive the cover plate 2 to move toward or away from the roller brush 1 based on the comparison result of the pressure value and the first pressure threshold.

[0042] In this embodiment, the pressure value applied by the cover plate 2 to the cleaning member 1 is detected by the pressure detection unit 4, and then the pressure value is compared with the first pressure threshold. If the pressure value is greater than the first pressure threshold, the cover plate 2 is driven by the driving component 5 to move in the direction away from the cleaning member 1 to reduce the pressure of the cover plate 2 on the cleaning member 1. If the pressure value is less than the first pressure threshold, the cover plate 2 is driven by the driving component 5 to move in the direction close to the cleaning member 1 to increase the pressure of the cover plate 2 on the cleaning member 1. In this way, no matter how the size of the cleaning member 1 changes, that is, even if the diameter of the cleaning member 1 is reduced due to long-term wear, the pressure applied by the cover plate 2 on the cleaning member 1 can be kept constant, thereby ensuring sufficient contact between the cover plate 2 and the cleaning member 1, and thereby improving the cleaning effect of the cleaning member 1 on the cover plate 2.

[0043] The first pressure threshold may be set by the staff according to actual conditions and is not strictly limited in this embodiment.

[0044] Furthermore, as shown in Figure 1, a scraper is also provided on the cover plate 2, and the pressure detection part 4 is also used to detect the pressure value applied by the cover plate 2 to the cleaning member 1 when the cleaning equipment is cleaning or cleaning the cleaning member 1; the driving component 5 is also used to drive the cover plate 2 to move toward or away from the cleaning member 1 based on the comparison result of the pressure value and the second pressure threshold, so that the scraper moves toward or away from the cleaning member 1.

[0045] When the cleaning device is in operation, the cleaning element 1 rotates at high speed. Most of the dirty liquid and dirt adhering to the cleaning element 1 will be intercepted by the scraper and then enter the suction channel through the suction port. After the cleaning device is in operation, the cleaning element 1 will undergo a self-cleaning process. During the self-cleaning process, the cleaning element 1 is cleaned by soaking the cleaning element 1, flushing it with a large flow of water, and scraping it with the scraper.

[0046] In this embodiment, when the cleaning equipment is performing a cleaning operation or cleaning the cleaning member 1, the pressure value applied by the cover plate 2 to the cleaning member 1 is detected by the detection component, and then based on the comparison result of the pressure value with the second pressure threshold, the driving component 5 is used to drive the cover plate 2 to move toward or away from the cleaning member 1. Specifically, if the pressure value is greater than the second pressure threshold, the cover plate 2 is driven by the driving component 5 to move in the direction away from the cleaning member 1, thereby the scraper on the cover plate 2 also moves in the direction away from the cleaning member 1, thereby reducing the pressure of the scraper on the cleaning member 1; if the pressure value is less than the first pressure threshold, the cover plate 2 is driven by the driving component 5 to move in the direction close to the cleaning member 1, thereby the scraper on the cover plate 2 also moves in the direction close to the cleaning member 1, thereby increasing the pressure of the scraper on the cleaning member 1, so that no matter how the size of the cleaning member 1 changes, that is, even if the diameter of the cleaning member 1 is reduced due to long-term wear, the pressure applied by the scraper on the cleaning member 1 can be kept constant, thereby ensuring full contact between the scraper and the cleaning member 1, thereby improving the scraping effect of the scraper on the dirty liquid and dirt on the cleaning member 1 and the cleaning effect of the scraper on the cleaning member 1; and there is no need to add additional components, which simplifies the structure and reduces the cost.

[0047] The second pressure threshold is positively correlated with the first pressure threshold. In some embodiments, the second pressure threshold is proportional to the first pressure threshold. The specific proportional value can be set by the staff and is not strictly limited in this embodiment.

[0048] Furthermore, as shown in FIG1 , FIG2 and FIG3 , the pressure detection unit 4 includes a pressure sensor 41 and an elastic push rod 42 . The elastic push rod 42 is located on a side of the pressure sensor 41 close to the cover plate 2 , and the elastic push rod 42 can contact the cover plate 2 .

[0049] The elastic push rod 42 contacts the cover plate 2 so that the cover plate 2 applies pressure to the elastic push rod 42. The pressure is transmitted to the pressure sensor 41 through the elastic push rod 42, thereby measuring the pressure value, which can be regarded as the pressure value applied by the cover plate 2 to the cleaning member 1.

[0050] The elastic push rod 42 buffers the pressure on the cover plate 2 , thereby preventing the pressure sensor 41 from being damaged due to excessive pressure on the cover plate 2 .

[0051] Furthermore, as shown in Figure 4, the elastic push rod 42 includes a hollow elastic rod body 422 and a push head 421; one end of the elastic rod body 422 is connected to the push head 421, and the other end of the elastic rod body 422 is connected to the pressure sensor 41; an elastic component 423 is provided inside the elastic rod body 422, one end of the elastic component 423 abuts against the push head 421, and the other end of the elastic component 423 abuts against the pressure sensor 41.

[0052] The elastic component 423 can be made of elastic components such as elasticity. The elastic rod 422 can be made of elastic materials such as rubber.

[0053] In this embodiment, the hollow elastic rod can well limit the elastic component 423. Moreover, the elastic component 423 can buffer the pressure of the cover plate 2 and transmit the pressure, which has the advantages of simple structure, low cost and easy implementation.

[0054] Furthermore, as shown in Figures 1, 2 and 3, the driving assembly 5 includes a driving part 53, a transmission shaft 52 and at least one set of transmission connection components 51; each set of transmission connection components 51 includes a push block, a transmission gear 511 and a rack 512, the transmission gear 511 is fixed on the transmission shaft 52, the push block is arranged at a position corresponding to the transmission gear 511 on the cover plate 2, the rack 512 is installed on the push block in a direction parallel to the elastic push rod 42, and the transmission gear 511 is engaged with the rack 512; the driving part 53 is transmission-connected to the transmission shaft 52.

[0055] When the pressure value detected by the pressure detection part 4 is greater than the first pressure threshold or the second pressure threshold, the driving part 53 is used to drive the transmission shaft 52 to rotate in the first direction, and then the transmission shaft 52 drives the transmission gear 511 to rotate, so that the rack 512 engaged with the transmission gear 511 moves, thereby driving the push block to move in the direction close to the cleaning member 1, and then the cover plate 2 connected to the push block moves in the direction parallel to the elastic push rod 42 and away from the cleaning member 1, that is, the upward arrow direction as shown in Figure 1, and at the same time, the cover plate 2 also gradually moves away from the elastic push rod 42, so that the pressure of the cover plate 2 on the elastic push rod 42 is reduced, and then the pressure value measured by the pressure detection part 4 is reduced, that is, the pressure of the cover plate 2 and the scraper on the cover plate 2 on the cleaning member 1 is reduced. Similarly, when the pressure value detected by the pressure detection part 4 is less than the first pressure threshold or the second pressure threshold, the driving part 53 is used to drive the transmission shaft 52 to rotate in a direction opposite to the first direction, and then the transmission shaft 52 is used to drive the transmission gear 511 to rotate, so that the rack 512 engaged with the transmission gear 511 moves, thereby driving the push block to move in a direction parallel to the elastic push rod 42 and away from the cleaning member 1, that is, the downward arrow direction as shown in Figure 1, and at the same time, the cover plate 2 also gradually approaches the elastic push rod 42, so that the pressure of the cover plate 2 on the elastic push rod 42 increases, and then the pressure value measured by the pressure detection part 4 increases, that is, the pressure of the cover plate 2 and the scraper on the cover plate 2 on the cleaning member 1 increases, thereby achieving the purpose of adjusting the pressure applied by the cover plate 2 or the scraper on the cleaning member 1.

[0056] In this embodiment, transmission is achieved through the cooperation of the rack 512 and the transmission gear 511, thereby improving the transmission accuracy, thereby achieving the purpose of accurately controlling the movement of the push block, and also achieving the purpose of accurately controlling the cover plate 2.

[0057] Furthermore, as shown in FIG2 , the driving portion 53 includes a driving member 531 , a reduction gear set 532 and a driving gear 533 ; the driving gear 533 is fixed on the transmission shaft 52 , the driving member 531 is connected to the reduction gear set 532 , and the reduction gear set 532 is meshed with the driving gear 533 .

[0058] The driving member 531 may be a component capable of providing driving force, such as a motor, and this embodiment does not impose a strict limitation thereto.

[0059] The speed of the driving member 531 is adjusted by the reduction gear set 532 so that the speed of the driving gear 533 can reach a preset speed. The reduction gear set 532 has the advantages of smooth transmission, simple and reliable structure, and long service life.

[0060] Furthermore, as shown in FIG. 1 and FIG. 2 , the driving gear 533 is located in the middle of the transmission shaft 52 , thereby enabling better synchronization of the rotation of various parts of the transmission shaft 52 .

[0061] Furthermore, as shown in FIG2 , there are two groups of transmission connection assemblies 51 , wherein the transmission gear 511 of one group of transmission connection assemblies 51 is arranged at one end of the transmission shaft 52 , and the transmission gear 511 of the other group of transmission connection assemblies 51 is arranged at the other end of the transmission shaft 52 .

[0062] By providing two sets of transmission connection components 51 , the force acting on the cover plate 2 can be made more uniform, thereby improving the synchronization of the movements of various parts of the cover plate 2 .

[0063] Furthermore, the first pressure threshold changes as the cleaning mode of the cover plate 2 changes.

[0064] The cleaning modes of the cover plate 2 may include but are not limited to normal cleaning mode and strong cleaning mode. Different cleaning modes have different first pressure thresholds. For example, the first pressure threshold corresponding to the normal cleaning mode is smaller than the first pressure threshold of the strong cleaning mode.

[0065] By setting different cleaning modes for the cover plate 2, a flexible selection can be made according to the dirtiness of the cover plate 2. For example, if the dirtiness of the cover plate 2 is not very serious, the normal cleaning mode can be selected, and the first pressure threshold is relatively small, that is, the pressure applied by the cover plate 2 to the cleaning member 1 is relatively small, so that the contact degree between the cover plate 2 and the cleaning member 1 is relatively small, thereby ensuring the cleaning effect of the cover plate 2 while reducing the wear of the cleaning member 1. If the dirtiness of the cover plate 2 is more serious, the strong cleaning mode can be selected, and the first pressure threshold is relatively large, that is, the pressure applied by the cover plate 2 to the cleaning member 1 is relatively large, so that the contact degree between the cover plate 2 and the cleaning member 1 is relatively large, thereby improving the cleaning effect of the cleaning member 1 on the cover plate 2.

[0066] An embodiment of the present application further provides a cleaning system, comprising a base station and the cleaning device provided in any of the aforementioned embodiments.

[0067] The base station is used in conjunction with the cleaning device. The cleaning device can be docked on the base station, or the cleaning device can depart from the base station.

[0068] Furthermore, when the cleaning device starts working, it starts from the base station to perform the cleaning task. When the cleaning device completes the cleaning task or other situations require the cleaning task to be suspended, the self-cleaning device can return to the base station for charging, and / or water replenishment, and / or cleaning, and / or dust collection, etc.
