Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning module and a cleaning device having the cleaning module. Background Technology

[0002] In cleaning equipment such as robot vacuums and sweepers, roller assemblies are typically used to clean floors.

[0003] In the relevant solutions, the rotation axis of the roller in the roller assembly is set in the horizontal direction, and a cloth can be installed on the circumferential surface of the roller, so that the floor can be cleaned by driving the roller to rotate through the cloth on the roller surface.

[0004] However, it was found that when cleaning the floor, the roller assembly mentioned above either sprays water onto the roller cloth to clean dry, sticky dirt, or wipes the water off the roller cloth to clean wet, liquid dirt. In other words, the existing cleaning equipment's roller assembly can usually only select one of the floor mopping or washing modes, and cannot do both at the same time, which leads to inconvenience in use.

[0026] Among them, a plurality of the second spray nozzles are arranged on the spray plate along the first direction.

[0027] This application embodiment also provides a cleaning device, which includes the cleaning module described above.

[0028] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0029] This application provides a cleaning module and a cleaning device having the cleaning module. The cleaning module includes a support unit and a roller unit rotatably mounted on the support unit. The roller unit includes a roller and a cleaning component attached to the cylindrical surface of the roller. The support unit is equipped with a drive unit for driving the roller to rotate unidirectionally. Along the rotation direction of the roller, the support unit of this embodiment has a first spray port preceding the first spray port and a second spray port following the first spray port. The two spray ports are used to spray liquids such as clean water onto the cleaning component of the roller. Then, this embodiment provides a squeegee between the two spray ports for scraping off the liquid absorbed by the cleaning component. Furthermore, this embodiment configures the opening and closing of the two spray ports to be independently controlled. Thus, the cleaning module disclosed in this embodiment can switch between different cleaning modes according to the independent opening and closing of the two spray ports, thereby solving the technical problem that existing roller assemblies cannot accommodate different cleaning modes, and is convenient to use.

[0030] For example, when the floor mopping mode is needed, the cleaning module of this embodiment can open the first spray nozzle and close the second spray nozzle. At this time, during the rotation of the roller, the first spray nozzle located before the squeegee will spray clean water onto the cleaning part of the roller. Then, the cleaning part is scraped off the excess clean water by the squeegee. In this way, the slightly dry cleaning part can clean the slightly wet liquid dirt on the floor.

[0031] When the floor washing mode is needed, the cleaning module of this embodiment can open the second spray nozzle. At this time, as the roller rotates, the second spray nozzle located after the squeegee will spray clean water onto the cleaning component of the roller. In this way, the slightly wet cleaning component can clean the slightly dry, adhered dirt on the floor.

[0032] In the floor washing mode, the first spray nozzle in this embodiment can be opened or closed. When the first spray nozzle is opened, it can spray clean water onto the cleaning component after cleaning the floor. Combined with the squeegee component, the cleaning component is squeegeed to remove water, thus cleaning the cleaning component and further diluting the dirt on it, achieving a deep floor washing effect.

[0050] To better understand the above technical solutions, exemplary embodiments of this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0051] Figure 1 This is a schematic diagram of the exploded structure of the cleaning module. Figure 2 This is a cross-sectional structural diagram of the cleaning module. Please refer to it. Figure 1 , Figure 2 A cleaning module includes a support unit 10, a roller unit 20, and a drive unit 30. The roller unit 20 is rotatably mounted on the support unit 10 and includes a roller 212 extending along a first direction X. A cleaning element 22 is attached to the cylindrical surface of the roller 21. The drive unit 30 is fixedly mounted on the support unit 10 and is used to drive the roller 21 to rotate unidirectionally. Along the rotation direction of the roller 21, the support unit 10 is provided with a first spray nozzle 40 and a second spray nozzle 50 located behind the first spray nozzle 40. The openings of the first spray nozzle 40 and the second spray nozzle 50 face the roller 21 and are used to spray liquid onto the cleaning component 22; the support unit 10 is provided with an abutting squeegee 60 at a position between the first spray nozzle 40 and the second spray nozzle 50. The abutting squeegee 60 extends along the first direction X and is configured to abut against the cleaning component 22 and to scrape off the liquid absorbed by the cleaning component 22; and the opening and closing configurations of the first spray nozzle 40 and the second spray nozzle 50 are independently controlled so that the cleaning module switches the cleaning mode according to the independent opening and closing of the first spray nozzle 40 and the second spray nozzle 50.

[0052] Overall, combined Figure 2Along the rotation direction S of the roller, this embodiment sequentially sets a first spray nozzle, an abutting squeegee, and a second spray nozzle, and configures the opening and closing of the two spray nozzles to be independently controlled. Thus, the cleaning module of this embodiment can switch between different cleaning modes by adjusting the opening and closing of the two spray nozzles respectively.

[0053] Specifically, the cleaning module in this embodiment includes a support unit, a roller unit, and a drive unit.

[0054] The support unit serves as the frame for the cleaning module, providing a mounting base for the roller unit and drive unit.

[0055] The roller unit includes a roller, which is cylindrical for example, and extends in a first horizontal direction. The cylindrical surface of the roller is covered with a cleaning component. The roller is rotatably mounted on the support unit. It is understood that the cleaning component mentioned here in this embodiment should be made of a material that is easy to absorb water and convenient for cleaning the floor, such as a cleaning cloth.

[0056] The drive unit is fixedly mounted on the support unit, and is used to drive the roller unit to rotate in one direction. Please refer to... Figure 2 , Figure 2 The direction of rotation S of the roller is shown.

[0057] Then, the support unit of this embodiment is further provided with a first spray nozzle, a second spray nozzle with openings facing the roller, and a squeegee that abuts against the roller cloth.

[0058] When the drive unit drives the roller to rotate in one direction, the first spray nozzle and the second spray nozzle are used to spray liquid, such as clean water, onto the roller cloth. The abutting squeegee is used to scrape off the liquid absorbed by the roller cloth by abutting against it.

[0059] Furthermore, please combine Figure 2 Along the rotation direction S of the roller, the roller cloth will pass through the first spray nozzle, the abutting squeegee, and the second spray nozzle in sequence after passing the ground; that is, the second spray nozzle is in the rear position relative to the first spray nozzle, and the abutting squeegee is in the position between the two spray nozzles.

[0060] Based on the above structure, this embodiment configures the opening and closing of the two spray nozzles to be independently controlled. In this way, the cleaning mode can be switched by independently opening and closing the two spray nozzles. It can be understood that the independent control here means that the opening and closing of the two spray nozzles are separate and independently controlled. For example, the first spray nozzle can be open while the second spray nozzle is closed, or the first spray nozzle can be closed while the second spray nozzle is open, or both spray nozzles can be open.

[0061] It is understood that the cleaning module in this embodiment can switch cleaning modes by means of the independently controlled opening and closing of two spray nozzles.

[0062] For example, when the floor mopping mode is needed, the cleaning module of this embodiment can open the first spray nozzle and close the second spray nozzle. At this time, during the rotation of the roller, the first spray nozzle located before the squeegee will spray clean water onto the roller cloth. Then, the roller cloth is scraped off the excess clean water by the squeegee. In this way, the slightly dry roller cloth can clean the slightly wet liquid dirt on the floor.

[0063] When the floor washing mode is needed, the cleaning module of this embodiment can open the second spray nozzle. At this time, as the roller rotates, the second spray nozzle located after the squeegee will spray clean water onto the roller cloth. In this way, the slightly wet roller cloth can clean the slightly dry adhesive dirt on the floor.

[0064] In the floor cleaning mode, the first spray nozzle in this embodiment can be opened or closed. When the first spray nozzle is opened, it can spray clean water onto the roller cloth after cleaning the floor. Combined with the squeegee, the roller cloth can be cleaned and the dirt on the roller cloth can be further diluted, achieving a deep floor cleaning effect.

[0065] In one possible implementation, the first spray nozzle 40 is located above the first section 70, which is horizontal and passes through the axis of rotation of the roller 21; and the first spray nozzle 40 is located on the side of the roller 21 that is divided into upward rotation by the second section 80, which is vertical and passes through the axis of rotation of the roller 21.

[0066] The first cross-section and the second cross-section mentioned in this embodiment should be referred to in conjunction with... Figure 2 The first section 70 is horizontally arranged and passes through the rotating shaft of the roller. The first section 70 divides the roller into upper and lower parts. The first spray nozzle should be located above the first section relative to the first section. The second section 80 is vertically arranged and passes through the rotating shaft of the roller. The second section 80 divides the roller into left and right parts that rotate upward and downward. The first spray nozzle should be located on the side of the roller that rotates upward relative to the second section.

[0067] Thus, it can be understood that the water sprayed from the first spray nozzle moves downwards, while the roller absorbs the water and drives it upwards, which is beneficial for the roller to absorb the water.

[0068] In one possible implementation, the second spray nozzle 50 is located on the side of the roller 21 that is divided into upward rotation by the second section 80, which is perpendicular to the axis of rotation of the roller 21.

[0069] In this embodiment, relative to the second cross-section mentioned above, the second spray nozzle should be located on the side where the roller is divided into upward rotation sections; and, as mentioned above, along the rotation direction of the roller, the second spray nozzle should also be located behind the first spray nozzle; thus, it can be understood that the clean water sprayed from the second spray nozzle is sprayed onto the roller cloth before the roller cloth reaches its highest point, and then the roller cloth continues to rotate towards the highest point, which is conducive to the clean water penetrating into the roller cloth and is not easily thrown out.

[0070] In one possible implementation, the support unit 10 is provided with a wastewater tank 133; wherein the wastewater tank 133 extends along a first direction X and is configured to hold liquid scraped off by the self-cleaning component 22.

[0071] That is, for the sewage and other wastewater scraped off by the roller cloth by the abutting squeegee, the support unit of this embodiment can also be provided with a sewage tank to hold the sewage and other wastewater. The sewage tank should extend in the first direction to match the extension of the roller and the abutting squeegee in the first direction.

[0072] In one possible implementation, the roller 21 is hollow, and the drive unit 30 is installed inside the hollow part of the roller 21. By using the hollow part of the roller to install the drive unit, space can be saved, which is conducive to the miniaturization of the cleaning module.

[0073] Regarding the specific structure of the support unit 10 mentioned above, in one possible embodiment, the support unit 10 includes a main body 11, which is located above the roller 21. On one side of the roller 21 in the radial direction, the main body 11 extends downward to a side plate 12. The main body 11 and the side plate 12 extend along a first direction X. The first spray nozzle 40 is located on the inner side of the side plate 12 facing the roller 21, and the second spray nozzle 50 is located on the lower side of the main body 11 facing the roller 21.

[0074] That is, referring to the positions of the first spray nozzle and the second spray nozzle relative to the roller mentioned above, the support unit of this embodiment may specifically include a main body and a side plate. The main body is located vertically above the roller, and the main body extends downward to one side of the roller with a side plate. Thus, the first spray nozzle may be specifically located on the inside of the side plate facing the roller, and the second spray nozzle may be specifically located below the main body.

[0075] In one specific embodiment, a wastewater box 13 is provided on the inner side of the side plate portion 12 facing the roller 21, and the wastewater box 13 extends along the first direction X; along the radial direction of the roller 21, the wastewater box 13 includes a first side wall 131 close to the roller 21 and a second side wall 132 away from the roller 21, the first side wall 131 and the second side wall 132 extend along the first direction X, and a wastewater trough 133 is formed between the first side wall 131 and the second side wall 132, the wastewater trough 133 is used to collect the liquid scraped off by the self-cleaning component 22; wherein, a plurality of first spray nozzles 40 are arranged along the first direction X on the first side wall 131, and the second side wall 132 is used for fixed installation with the side plate portion 12.

[0076] In this embodiment, a sewage box can be installed between the side plate and the roller. The sewage box is specifically installed on the side plate via a second side wall near the side plate. Then, the first spray nozzle mentioned above can be specifically set on the first side wall of the sewage box near the roller. That is, a plurality of first spray nozzles are arranged in a straight line along the first direction on the first side wall. In this way, the setting of the first spray nozzle can be completed by means of the side wall of the sewage box, and the structure is simple.

[0077] In one specific embodiment, the wastewater box 13 includes a cover plate 134 extending along a first direction X, the cover plate 134 for sealing the wastewater tank 133; wherein, along the radial direction of the roller 21, the end of the cover plate 134 facing the roller 21 forms an abutment scraper 60.

[0078] In this embodiment, the abutting wiper can be set on the cover of the sewage box, or the abutting wiper can be integrated with the cover of the sewage box. This reduces the number of parts and simplifies the structure.

[0079] In one specific embodiment, the main body 11 carries a spray plate 14, which extends along a first direction X; wherein, a plurality of second spray nozzles 50 are arranged on the spray plate 14 along the first direction X.

[0080] In this embodiment, the main body is hollow for example, and the main body can carry a spray plate extending along the first direction. Then it is covered with the top cover 15. A plurality of second spray nozzles can be arranged on the spray plate along the first direction, thus completing the setting of the second spray nozzles.
