Detailed Description

In the related art, a base is generally included in a cleaning base station, and a water tank are provided on the base, and cleaning water is stored in the water tank and supplied to the water tank through a pipe or the like. In order to ensure the cleaning requirement for a certain number of times, the volume of the water tank cannot be made too small, which leads to a large cleaning base station, and therefore, the water tank cannot be suitable for a working environment with high space requirements.

In view of this, the embodiments of the present invention utilize the tank assembly in the cleaning device to provide the cleaning liquid to the cleaning tank, so that the cleaning base station does not need to be provided with a water tank, and thus the volume of the cleaning base station can be reduced.

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Example 1

The present embodiment provides a cleaning base station 100, and the cleaning base station 100 can be used for automatically cleaning a cleaning member 215 in a cleaning apparatus 200. It should be noted that the cleaning device 200 may include, but is not limited to, a common cleaning apparatus such as a dust collector, a floor cleaning machine, a floor cleaning robot, and a household appliance. In this embodiment, the cleaning device 200 is exemplified as a dust collector.

Fig. 1 is a schematic structural diagram of a cleaning base station according to an embodiment of the present application, fig. 2 is a schematic structural diagram of a cleaning base station according to an embodiment of the present application and a cleaning device used together, and fig. 3 is an exploded structural diagram of a cleaning base station according to an embodiment of the present application.

Referring to fig. 1, 2 and 3, the cleaning base station 100 of the present application includes a body 110, a cleaning tank 120 and a cleaning assembly 130. The body 110 serves as a base of the entire cleaning base station, and supports the cleaning apparatus 200. The cleaning tank 120 is configured to receive a cleaning liquid therein for immersion of the cleaning member 215. The cleaning assembly 130 may automatically clean the cleaning members 215 immersed in the cleaning tank 120.

Wherein the cleaning groove 120 may be provided on the body 110. In addition, in the present application, the cleaning liquid refers to a liquid for cleaning the cleaning member 215, and may be water, a mixed liquid of water and a cleaning liquid, or another type of liquid that can perform a cleaning function.

It is understood that the cleaning tank 120 may be formed separately from the body 110 or may be formed integrally with the body 110.

In the case where the cleaning groove 120 is formed separately from the body 110, referring to fig. 3, the body 110 may be exemplarily formed in a structure having a hollow inside, i.e., a hollow cavity 111 (refer to fig. 7 described below) is provided in the body 110, and the top of the hollow cavity 111 has an opening 112. And the cleaning groove 120 may be provided to cover the opening 112, in which case the groove body portion of the cleaning groove 120 may be entered into the hollow cavity 111, and the notch portion is located outside the hollow cavity 111. It will be appreciated that the slot edge of the cleaning tank 120 may be sealingly connected to the opening 112 to prevent cleaning liquid from entering the hollow cavity 111. Here, the notch edge of the cleaning tank 120 has an everted edge portion 113 that can overlap and cover just above the edge of the opening 112, sealing the opening 112.

In the case where the cleaning groove 120 is integrally formed with the body 110, the shape, configuration, etc. of the cleaning groove 120 are similar to those of the above-described separate formation, except that the cleaning groove 120 and the body 110 are integrally formed during production, for example, may be integrally formed by injection molding.

In some embodiments, to facilitate immersion of the cleaning member 215 into the cleaning tank 120, the cleaning tank 120 may be disposed on top of the body 110, such as on an upper surface of the body 110. In addition, the notch of the cleaning tank 120 may be located at the top surface of the cleaning tank 120. It is understood that the arrangement position of the cleaning tank 120 includes, but is not limited to, other positions, such as on the side of the body 110, etc.

In the embodiment of the present application, the cleaning assembly 130 includes an ultrasonic generator 140, the ultrasonic generator 140 is disposed on the cleaning tank 120, and the ultrasonic wave emitted by the ultrasonic generator 140 is used to act on the cleaning liquid to clean the cleaning assembly.

The ultrasonic cleaning process includes dispersing, emulsifying and stripping the dirt layer to obtain the cleaning effect. Specifically, ultrasonic waves generate acoustic cavitation when propagating in the cleaning liquid. The shock waves emitted when cavitation bubbles are suddenly closed can create thousands of atmospheres around them, impacting directly and repeatedly on the dirt layer, on the one hand destroying the adsorption of dirt onto the surface of the cleaning member 215, and on the other hand also causing the destruction of the dirt layer to detach from the surface of the cleaning member 215 and disperse them into the cleaning liquid. And the bubbles can also "dig into" the crack to vibrate, so that the deeper dirt can be removed.

As described above, since the ultrasonic generator 140 is provided on the cleaning tank 120, the ultrasonic wave emitted therefrom can generate cavitation of the cleaning liquid and generate a large amount of bubbles which continuously impact the cleaning member 215 immersed in the cleaning liquid, not only is the cleaning efficiency high, but also the cleaning effect is excellent as compared with the manual cleaning in the related art. In the present application, the ultrasonic generator 140 may be an ultrasonic vibrator.

In the embodiment of the present application, the ultrasonic generator 140 may be disposed on the side groove wall 121 of the cleaning groove 120, specifically, the ultrasonic generator 140 may be disposed only on the inner side surface of the side groove wall 121; or the ultrasonic generator 140 may be provided only on the outer side surface of the side tank wall 121; alternatively, the ultrasonic generator 140 is provided on both the inner and outer surfaces of the side groove wall 121. In view of the convenience of cleaning, the present application will be described by taking the case where the ultrasonic generator 140 is disposed on the outer side surface of the side groove wall 121 as an example, and the description thereof will be omitted herein for the case where the ultrasonic generator 140 is disposed at other positions. It should be noted that the ultrasonic generator 140 is disposed on the outer side surface of the side groove wall 121, specifically, the ultrasonic generator 140 is attached to the wall surface of the cleaning groove 120 facing the inside of the hollow cavity 111. The ultrasonic generator 140 may be adhered to the wall surface of the cleaning tank 120 facing the inside of the hollow cavity 111 by an adhesive such as glue.

It will be appreciated that the ultrasonic generator 140 can be located closer to the notch of the cleaning tank 120 than it is located elsewhere when located on the side tank wall 121, since the cleaning liquid bubbles in the vicinity of the ultrasonic wave generating source are more numerous and more powerful in number and energy, so that more cleaning liquid bubbles accumulate in the vicinity of the side tank wall 121, i.e., in the vicinity of the cleaning member 215, to enhance the cleaning effect on the cleaning member 215.

Fig. 4a is a longitudinal sectional view of a structure for cleaning a cleaning tank in a base station according to an embodiment of the present application. With reference to fig. 3 and 4a, it may be understood that the cleaning groove 120 may include side groove walls 121 and bottom groove walls 122, each side groove wall 121 is surrounded by the bottom groove walls 122, and bottom ends of each side groove wall 121 are connected with each edge of the bottom groove walls 122, so that each side groove wall 121 and the bottom groove wall 122 together form the cleaning groove 120. The ultrasonic generator 140 is disposed on the outer side surface of the side groove wall 121, and it is understood that at this time, the ultrasonic generator 140 is disposed in the hollow cavity 111, and the cleaning groove 120 covers the opening 112 of the hollow cavity 111, and the ultrasonic generator 140 is disposed in a relatively closed space, which is not easily contaminated by external water stains, dirt, etc.

In addition, referring to fig. 4b, in some embodiments, the cleaning tank 120a may include side tank walls 121a, where each side tank wall 121a is connected end to end and encloses a tank body of the cleaning tank 120a, and the ultrasonic generator 140 is located on an outer surface of the side tank wall 121 a.

It will be appreciated that for better cleaning, the number of ultrasonic generators 140 may be more, and the side walls 121 may include a first side wall 123 and a second side Fang Caobi on opposite sides, for example, referring to fig. 3, a portion of the ultrasonic generators 140 may be attached to the first side wall 123, and another portion of the ultrasonic generators 140 may be attached to the second side wall 124 opposite to the first side wall 123. Thus, the ultrasonic generators 140 are disposed on both sides of the cleaning member 215, and cooperate with each other to further enhance the cleaning effect. Of course, fig. 3 shows an example in which the ultrasonic generators 140 are provided on the first side groove wall 123 and the second side groove wall 124, but may be provided on the other pair of opposite side groove walls, as long as the ultrasonic generators 140 are provided on the side walls on the opposite sides, respectively.

It should be noted that the placement of the ultrasonic generator 140 includes, but is not limited to, the opposite side groove walls 121, such as the cleaning groove 120 shown in fig. 3, and the ultrasonic generator 140 may be disposed on each of the four side groove walls 121 in fig. 3. Or the ultrasonic generator 140 is arranged on each of the three side groove walls 121, or the ultrasonic generator 140 is arranged on only one side groove wall 121, and all the changes fall into the protection scope of the application.

In this embodiment, the longitudinal section shape of the cleaning groove 120 may be set as required, and the interval between the two side groove walls 121 of the cleaning groove 120 along the length direction L gradually increases from the groove bottom to the groove opening. For example, as shown in fig. 4a and 4b, the distance between two opposite side groove walls 121 is gradually increased from the groove bottom to the groove opening, and the distance between two opposite side groove walls 121a is gradually increased from the groove bottom to the groove opening. Since the cleaning members 215 enter the cleaning tank 120 from the notch, they are located approximately at the middle upper portion of the cleaning tank 120. This arrangement can allow more cleaning liquid to contact the cleaning member 215 with a constant amount of cleaning liquid, thereby improving the cleaning effect of the cleaning member 215.

Alternatively, the side groove walls of the cleaning groove may extend in the depth direction of the cleaning groove, and for example, the cleaning groove shown in fig. 4c and 4d may be formed substantially as a square groove. In contrast, in fig. 4c, the depth direction D and width direction H of the cleaning tank 120b are substantially the same, and the ultrasonic generator 140 may be disposed on a set of opposite side tank walls 121 b. In fig. 4D, the width direction H dimension of the cleaning groove 120c is significantly larger than the depth direction D dimension of the cleaning groove 120c, resulting in a shallower cleaning groove 120c, at which time the ultrasonic generator 140 may be disposed on the outer surface of the bottom groove wall 122 c.

Fig. 5 is a schematic structural diagram of a cleaning tank in a cleaning base station according to an embodiment of the present application, fig. 6 is a longitudinal sectional view of a cleaning tank in a cleaning base station according to an embodiment of the present application, fig. 7 is a schematic structural diagram of a cleaning base station and a cleaning device according to an embodiment of the present application, and fig. 8 is a partial enlarged view of a portion a in fig. 7.

Referring to fig. 3 and 5-8, in order to further enhance the cleaning effect of the cleaning assembly, in the embodiment of the present application, the cleaning assembly 130 may be further modified on the basis of the above-mentioned arrangement of the ultrasonic generator, and the cleaning assembly 130 further includes a wiper strip 150. The wiper strip 150 may be disposed in the cleaning slot 120, and the wiper strip 150 is configured to abut against a surface of the cleaning member 215 of the cleaning device 200 to clean the surface of the cleaning member 215.

The cleaning member 215 of the cleaning device 200 may be provided as needed, and in this application, the cleaning member 215 is exemplified as the roll brush 210. Those skilled in the art will appreciate that the cleaning members 215 may also be of other types and forms, such as tracked cleaning belts and the like.

Specifically, referring to fig. 5 and 8, the wiper strip 150 may be suspended, i.e., the wiper strip 150 is suspended in the notch region of the cleaning tank 120. Because the length direction of the rolling brush 210 is approximately consistent with the length direction L of the cleaning groove 120 when the rolling brush 210 is immersed in the cleaning groove 120, if the scraping strip 150 extends along the length direction L of the cleaning groove 120 and the scraping strip 150 is suspended, the scraping strip 150 can just abut against the surface of the rolling brush 210, and at this time, the rolling brush 210 rotates, and the scraping strip 150 can play a role in scraping dirt on the surface of the rolling brush 210.

Specifically, the scraping strip 150 is transversely arranged in the cleaning groove 120, so that after the ultrasonic generator 140 starts to operate, the outer surface of the rolling brush 210 rotates at a certain speed, and then moves relative to the scraping strip 150. The relative movement of the scraper bar 150 and the pile layer on the outer surface of the roller brush 210 causes the dirt on the pile layer to be peeled off from the body of the pile layer, and the peeled dirt can be sucked into a waste liquid tank 230 (see fig. 10 described below). In addition, the scraping strip 150 also plays a role in guiding ultrasonic wave propagation in the cleaning liquid medium, so that energy can be distributed in the cleaning liquid more uniformly.

It is understood that in the case where the wiper strip 150 is suspended in the cleaning tank 120, both end portions of the wiper strip 150 may be connected to the side tank walls 121c, 121c at both ends of the cleaning tank 120 in the length direction, respectively. In this way, it is convenient to set the length of the wiper strip 150 longer. In addition, in the present embodiment, the scraping strip 150 may have an elongated shape, for example, a cylindrical shape or a sheet shape.

In one possible embodiment, the height of the wiper strip 150 disposed within the cleaning tank 120 cannot be too low, for example, the height of the cleaning tank 120 may be set below the working water line of the cleaning tank 120. This allows the cleaning member 215 to abut the wiper strip 150 when immersed below the working water line.

Further, the number of the scraping bars 150 may be set as required, and for the cleaning member 215 shown in fig. 7, a plurality of scraping bars 150 may be provided, and the respective scraping bars 150 are arranged in parallel and at a spacing, and for example, two scraping bars 150 may be provided. Referring to fig. 6 and 7, considering that the cleaning member 215 is positioned substantially right of the cleaning tank 120 (right side in the drawing of fig. 7) when immersed in the cleaning tank 120, both of the wiper strips 150 may be disposed to the right.

In addition, in order to detect the level of the cleaning liquid in the cleaning tank 120, it is also conceivable to provide a liquid level sensor in the cleaning tank 120.

In this embodiment, in order to make the cleaning device 200 be supported on the body 110 more firmly, some structures for assisting positioning may be provided. Referring to fig. 1 and 2, an exemplary embodiment of the present invention includes a positioning groove 114 on the top of the body 110, and a groove wall of the positioning groove 114, particularly, a groove body surrounded by a side groove wall, is shaped to match with an external shape of the cleaning device 200, so that when the cleaning device 200 is placed in the positioning groove 114, an external contour of the cleaning device 200 can be fitted with the groove wall of the positioning groove 114, so that positioning of the cleaning device 200 is more stable.

The positioning groove 114 has a positioning portion 115 at a groove bottom, and the positioning portion 115 is configured to be in contact with a traveling mechanism of the cleaning device 200. The running mechanism of the cleaning device 200 may be, for example, a roller 211, so that the positioning portion 115 is used to position the roller 211.

For example, the positioning portion 115 may be plural, the plural positioning portions 115 may include the roller groove 116 and the stopper protrusion 117, or the positioning portion 115 may include only the roller groove 116, or the positioning portion 115 may include only the stopper protrusion 117. Referring to fig. 1, the roller groove 116 may be opened at the bottom of the positioning groove 114. The stop projection 117 may protrude upward from the bottom of the detent 114. Referring to fig. 2, in the case that the positioning groove 114 is provided with both the roller 211 116 and the stop protrusion 117, the bottom of the roller 211 may be positioned in the roller groove 116, and the middle of the wheel surface of the roller 211 may abut against the stop protrusion 117, so that the roller 211 may be well positioned.
