Technical Field
[0001] This disclosure relates to the field of cleaning equipment technology, and in particular to a cleaning device. Background Technology
[0002] With the development of technology and the improvement of people's living standards, cleaning equipment is increasingly being used in various fields. For example, cleaning equipment (robot vacuum cleaners, floor scrubbers, etc.) frees people from tedious cleaning work, keeps the home and office environment clean, and allows people to enjoy more free time, which is why they are favored by people.
[0003] In related technologies, cleaning equipment can improve cleaning effectiveness by spraying foam onto the surface to be cleaned. However, when spraying foam, it is crucial to ensure uniformity and proper coverage to avoid uneven foam distribution that could reduce cleaning efficiency. Utility Model Content
[0004] In view of this, the present disclosure provides a cleaning device that, when in operation, can spray evenly distributed foam onto the surface to be cleaned, and the foam can better cover the surface to be cleaned, which is beneficial to improving the cleaning effect of the cleaning device.
[0005] Specifically, this disclosure is achieved through the following technical solution:
[0006] According to a first aspect of the present disclosure, a cleaning device is provided, comprising a foam generator, a delivery pipe, and an output component. The delivery pipe is connected to the foam generator. The output component includes a connecting portion, and the output component is connected to the delivery pipe via the connecting portion. The output component has an output port, which communicates with the delivery pipe to output foam through the output port. The projected length of the output port on the cross-section of the connecting portion is less than or equal to the inner diameter of the delivery pipe.

[0008] During the assembly of the cleaning equipment, the foam generator is connected to the delivery pipe, which in turn is connected to the output component via a connector. This allows the foam generator to be connected to the output component through the delivery pipe. When the cleaning equipment is operating, the foam generator produces foam and delivers it through the delivery pipe to the output component. Finally, the foam is output from the outlet to the surface to be cleaned, enabling the cleaning equipment to use the foam for cleaning. By designing the projected length of the outlet on the cross-section of the connector to be less than or equal to the inner diameter of the delivery pipe, not only is the amount of cleaning agent used reduced, but when the outlet outputs foam to the surface, it also sprays evenly distributed foam, allowing for better coverage and thus improving the cleaning effect of the equipment.

[0011] In one embodiment, the output member has a receiving cavity communicating with the conveying pipe, and the output member includes an output section connected to the connecting portion, the output section being hemispherical. An output port is disposed on the output section and communicates with the receiving cavity.
[0012] In one embodiment, the opening angle of the output port is 30° to 130°.
[0013] In one embodiment, the projection center of the output port on the cross-section of the connector coincides with the center of the hemispherical output port.
[0014] In one embodiment, the output section and the connection section are integrally formed.
[0015] In one embodiment, the output component includes an inner wall and an outer wall disposed opposite to the inner wall, and the output opening gradually narrows along the direction from the outer wall to the inner wall.
[0016] In one embodiment, the output port includes a first opening located on the inner wall and a second opening located on the outer wall. The height of the first opening is 0.2 mm to 0.4 mm, and / or the height of the second opening is 0.3 mm to 0.7 mm.

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this application. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this application.
[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.
[0039] With the development of technology and the improvement of people's living standards, cleaning equipment is increasingly being used in various fields. For example, cleaning equipment (robot vacuum cleaners, floor scrubbers, etc.) frees people from tedious cleaning work, keeps the home and office environment clean, and allows people to enjoy more free time, which is why they are favored by people.
[0040] In related technologies, cleaning equipment can improve cleaning effectiveness by spraying foam onto the surface to be cleaned. However, when spraying foam, it is crucial to ensure uniformity and proper coverage to avoid uneven foam distribution that could reduce cleaning efficiency.
[0041] Based on this, the present disclosure provides a cleaning device that, when in operation, can spray a small amount of cleaning liquid onto the surface to be cleaned to produce evenly distributed foam, and the foam can better cover the surface to be cleaned, which is beneficial to improving the cleaning effect of the cleaning device.
[0042] like Figure 1 as well as Figure 2 As shown, in some embodiments, a cleaning device 10 is provided. The cleaning device 10 includes a cleaning brush device 100, a main body device 200, and a control device (not shown). The main body device 200 is connected to the cleaning brush device 100. The control device can be used to control, coordinate, and manage the operation of the various devices on the cleaning device 10, ensuring that the cleaning device 10 can complete the cleaning task efficiently and accurately. Specifically, the cleaning device 10 can be a sweeping robot, a mopping robot, or a floor scrubber, etc.
[0043] like Figure 1 as well as Figure 2 As shown, in some embodiments, the cleaning brush device 100 includes a housing assembly 300 and a floor brush member 400. The floor brush member 400 is mounted on the housing assembly 300. Thus, when the cleaning device 10 is in operation, the cleaning device 10 can use the floor brush member 400 to clean the surface to be cleaned.
[0044] In some embodiments, the floor brush 400 is rotatably connected to the housing assembly 300. Thus, the surface to be cleaned is achieved by the rolling of the floor brush 400.
[0045] Of course, in other embodiments, the floor brush 400 may be fixedly connected to the housing assembly 300.
[0046] like Figures 3 to 6 As shown, in some embodiments, the cleaning brush device 100 includes a foam generator 500, a delivery pipe 600, and an output component 700. The delivery pipe 600 is connected to the foam generator 500. The output component 700 includes a connecting portion 710, through which the output component 700 is connected to the delivery pipe 600. The output component 700 has an output port 720, which communicates with the delivery pipe 600 to output foam. The projected length of the output port 720 on the cross-section of the connecting portion 710 is less than or equal to the inner diameter of the delivery pipe 600.
[0047] Thus, during the assembly of the cleaning equipment 10, the foam generator 500 is connected to the delivery pipe 600, and the delivery pipe 600 is connected to the output component 700 via the connecting part 710, allowing the foam generator 500 to be connected to the output component 700 through the delivery pipe 600. When the cleaning equipment 10 is operating, the foam generator 500 generates foam and delivers it to the output component 700 via the delivery pipe 600, finally outputting it to the surface to be cleaned through the output port 720, enabling the cleaning equipment 10 to use the foam for cleaning. By designing the projected length of the output port 720 on the cross-section of the connecting part 710 to be less than or equal to the inner diameter of the delivery pipe 600, when the output port 720 outputs foam to the surface to be cleaned, it can spray evenly distributed foam onto the surface, allowing the foam to better cover the surface and improving the cleaning effect of the cleaning equipment 10.
[0048] It should be noted that, as Figure 8 The figure shows the projection of the output port 720 onto the cross-section of the connecting portion 710, where a is the projection length of the output port 720 onto the cross-section of the connecting portion 710.
[0049] It should be noted that the inner diameter of the conveying pipe 600 is the inner diameter of the conveying pipe 600.
[0050] like Figure 7 as well as Figure 8 As shown, in some embodiments, the ratio of the projected length of the output port 720 on the cross-section of the connecting portion 710 to the inner diameter of the conveying pipe 600 is 2:5 to 4:5. Thus, by designing the ratio of the projected length of the output port 720 on the cross-section of the connecting portion 710 to the inner diameter of the conveying pipe 600 within the range of 2:5 to 4:5, the structure of the output component 700 is optimized, effectively improving the foam spraying effect. This allows the cleaning device 10 to spray evenly distributed foam, which better covers the surface to be cleaned, thereby improving the cleaning effect of the cleaning device 10 and reducing foam waste.
[0051] It should be noted that the ratio of the projected length of the output port 720 on the cross-section of the connecting part 710 to the inner diameter of the conveying pipe 600 to be 2:5 to 4:5 can be implemented in various ways, including 2:5, 2.5:5, 3:5, 3.5:5 and 4:5, etc.
[0052] In one example, the ratio of the projected length of the output port 720 on the cross-section of the connection 710 to the inner diameter of the delivery pipe 600 is 2:5.
[0053] In another example, the ratio of the projected length of the output port 720 on the cross-section of the connection 710 to the inner diameter of the delivery pipe 600 is 4:5.
[0054] like Figures 7 to 10 As shown, in some embodiments, the output component 700 is provided with a receiving cavity 730 communicating with the conveying pipe 600. The output component 700 includes an output portion 740 connected to the connecting portion 710, and the output portion 740 is hemispherical. An output port 720 is provided in the output portion 740 and communicates with the receiving cavity 730. Thus, by providing the receiving cavity 730 communicating with the conveying pipe 600 in the output component 700, and the receiving cavity 730 communicating with the output port 720, the foam generated by the foam generator 500 can be conveyed to the receiving cavity 730 through the conveying pipe 600, and finally output to the surface to be cleaned through the output port 720. By designing the output portion 740 as hemispherical and providing the output port 720 in the hemispherical output portion 740, it is beneficial for the foam output through the output port 720 to better cover the surface to be cleaned, achieving a fan-shaped diffusion spray of the foam.
[0055] like Figures 7 to 10 As shown, in some embodiments, the output portion 740 is hemispherical, so that a portion of the receiving cavity 730 is hemispherical. Thus, by designing the output as hemispherical, a portion of the receiving cavity 730 is a hemispherical cavity. When the cleaning device 10 is operating, the foam generator 500 generates foam and delivers it to the receiving cavity 730 via the delivery pipe 600, and finally outputs it to the surface to be cleaned through the output port 720. The hemispherical shape of the receiving cavity 730 facilitates foam filling of the hemispherical cavity, and during the process of outputting the foam from the hemispherical cavity to the surface to be cleaned through the output port 720, the resistance between the foam and the output portion 700 is reduced, allowing the foam to be delivered more smoothly through the hemispherical cavity to the output port 720.
[0056] like Figure 11 As shown, in some embodiments, the opening angle of the output port 720 is 30° to 130°. Thus, the output port 720 is disposed on the hemispherical output portion 740, and the output port 720 is positioned along the hemispherical surface of the output portion 740, giving the output port 720 a certain curvature. By designing the opening angle (i.e., curvature) of the output port 720 to be 30° to 130°, it is beneficial for the foam to be sprayed in a fan-shaped pattern when output from the cleaning device 10, so that the foam can cover the lateral range of the brush member 400, thereby improving the cleaning effect of the cleaning device 10.
[0057] It should be noted that there are various ways to implement the opening angle of the output port 720 from 30° to 130°, including opening angles of 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 105°, 110°, 115°, 120°, 125°, and 130°, etc.
[0058] In one example, the opening angle of output port 720 is 100°.
[0059] In another example, the opening angle of output port 720 is 110°.
[0060] In another example, the opening angle of output port 720 is 120°.
[0061] It should be noted that, as Figure 3 The angle b shown is the opening angle of the output port 720.
[0062] like Figure 7 as well as Figure 8 As shown, in some embodiments, the projection center of the output port 720 on the cross-section of the connecting portion 710 coincides with the center of the hemispherical output portion 740. Thus, by designing the projection center of the output port 720 on the cross-section of the connecting portion 710 to coincide with the center of the hemispherical output portion 740, the output port 720 is located at the center of the output portion 740. This facilitates better coverage of the surface to be cleaned and better coverage of the lateral range of the brush member 400 when the cleaning device 10 sprays foam through the output port 720, thereby improving the cleaning effect of the cleaning device 10.
[0063] like Figure 7 as well as Figure 9 As shown, in some embodiments, the output portion 740 and the connecting portion 710 are integrally formed. In this way, the assembly steps of the cleaning device 10 can be reduced, and the assembly efficiency of the cleaning device 10 can be improved.
[0064] In other embodiments, the output portion 740 and the connecting portion 710 are manufactured separately and then assembled. In this way, by manufacturing the output portion 740 and the connecting portion 710 separately and then assembling them, the output portion 740 and the connecting portion 710 can be repaired and replaced separately when the cleaning equipment 10 is maintained, which helps to reduce the maintenance and replacement costs of the cleaning equipment 10.
[0065] like Figure 9 as well as Figure 10 As shown, in some embodiments, the output member 700 includes an inner wall 750 and an outer wall 760 disposed opposite to the inner wall 750, and the output port 720 gradually narrows along the direction from the outer wall 760 to the inner wall 750. Thus, by designing the output port 720 to gradually narrow along the direction from the outer wall 760 to the inner wall 750 of the output member 700, it also gradually widens along the direction from the inner wall 750 to the outer wall 760. When the cleaning device 10 outputs foam through the output port 720, the foam is sprayed along the direction from the inner wall 750 to the outer wall 760, meaning the foam passes through the gradually widening output port 720. This facilitates the output port 720 to spray foam with a larger coverage area and more uniform distribution, thereby improving the cleaning effect of the cleaning device 10.
[0066] like Figure 9 as well as Figure 10 As shown, in some embodiments, the output port 720 includes a first opening 721 located on the inner wall 750 and a second opening 722 located on the outer wall 760. The height of the first opening 721 is 0.2mm to 0.4mm. Thus, by designing the height of the first opening 721 located on the inner wall 750 to be 0.2mm to 0.4mm, within this range, the output port 720 gradually narrows in the direction from the outer wall 760 to the inner wall 750, thereby better meeting the user's needs for the coverage and uniformity of the foam output by the cleaning device 10.
[0067] like Figure 9 as well as Figure 10 As shown, in some embodiments, the height of the second opening 722 is 0.3mm to 0.7mm. Thus, by designing the height of the second opening 722 located on the outer wall 760 to be 0.3mm to 0.7mm, and by utilizing the gradual narrowing of the output port 720 along the direction from the outer wall 760 to the inner wall 750, the coverage range and uniformity of the foam output by the cleaning device 10 can better meet the user's needs.
[0068] It should be noted that the height of the first opening 721 is Figure 10 As shown in Figure c, the height of the second opening 722 is Figure 10 As shown in d.
[0069] It should be noted that there are several ways to implement the height of the first port 721 from 0.2mm to 0.4mm, including heights of 0.2mm, 0.25mm, 0.3mm, 0.35mm, and 0.4mm, etc.
[0070] In one example, the height of the first port 721 is 0.3 mm.
[0071] It should be noted that there are several ways to implement the height of the second port 722, which is 0.3mm to 0.7mm. These include heights of 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, 0.55mm, 0.6mm, 0.65mm, and 0.7mm, etc.
[0072] In one example, the height of the second port 722 is 0.4 mm.
[0073] like Figure 5 as well as Figure 6As shown, in some embodiments, the housing assembly 300 is provided with a mounting groove 321, through which the foam generator 500 is detachably connected to the housing assembly 300. Thus, when the cleaning equipment 10 is assembled, the foam generator 500 can be installed on the housing assembly 300 by inserting it into the mounting groove 321. The detachable connection of the foam generator 500 to the housing assembly 300 via the mounting groove 321 facilitates the disassembly and installation of the foam generator 500, and allows for easy maintenance and replacement of the foam generator 500 during cleaning equipment 10 maintenance, thereby improving the maintenance convenience of the cleaning equipment 10.
[0074] like Figure 2 as well as Figure 3 As shown, in some embodiments, the housing assembly 300 includes a housing body 310 and a cover body 320 detachably connected to the housing body 310. Thus, by designing the cover body 320 to be detachably connected to the housing body 310, when it is necessary to clean or repair the components inside the cleaning equipment 10, the cover body 320 can be directly removed for easy cleaning or repair.
[0075] like Figure 6 as well as Figure 7 As shown, in some embodiments, the output component 700 further includes a mounting portion 770, through which the output component 700 is mounted on the cover body 320.
[0076] It should be noted that there are several ways in which the output component 700 can be installed on the cover body 320 via the mounting part 770, including snap-fit fixing, screw fixing, etc.
[0077] like Figure 5 as well as Figure 6 As shown, in some embodiments, the cover body 320 is provided with a mounting groove 321, and the foam generator 500 is detachably connected to the cover body 320 through the mounting groove 321. Thus, when disassembling the cleaning device 10, the cover body 320 is first removed from the shell body 310, at which point the cover body 320 and the foam generator 500 are removed together from the cover body 320, and then the foam generator 500 is removed from the cover body 320. When assembling the cleaning device 10, the foam generator 500 is first installed onto the cover body 320 through the mounting groove 321, and then the cover body 320 is placed over the shell body 310 to complete the assembly of the cleaning device 10.
[0078] like Figure 5 as well as Figure 6As shown, in some embodiments, the output component 700 is inclinedly disposed on the cover body 320, and the output port 720 faces the surface to be cleaned. In this way, by inclinedly disposing the output component 700 on the cover body 320 so that the output port 720 faces the surface to be cleaned, it is beneficial for the cleaning device 10 to output foam to the surface to be cleaned through the output port 720, and the foam can better cover the surface to be cleaned, thereby improving the cleaning effect of the cleaning device 10.
[0079] like Figure 5 as well as Figure 6 As shown, in some embodiments, the cleaning device 10 further includes a sealing ring 800, which is fitted onto the foam generator 500 and abuts against the side wall of the mounting groove 321. Thus, when the foam generator 500 is installed in the mounting groove 321, the sealing ring 800 abutting against the side wall of the mounting groove 321 ensures the sealing of the connection between the foam generator 500 and the output component, preventing leakage during foam output and improving the reliability of the cleaning device 10.
[0080] In some embodiments, the cleaning device 10 includes a clean water tank (not shown) for storing clean water and a cleaning liquid tank (not shown) for storing cleaning liquid. The mixture of clean water and cleaning liquid is used to generate foam, or only the cleaning liquid may be used to generate foam.
[0081] It should be noted that the clean water tank can be installed in the cleaning brush device 100 or in the main body device 200. Similarly, the cleaning liquid tank can also be installed in the cleaning brush device 100 or in the main body device 200.
[0082] like Figure 1 As shown, in some embodiments, the main body 200 of the cleaning device 10 is integrated with a handle, and the user moves the cleaning device 10 to perform cleaning by using the handle.
[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0084] The above embodiments are merely illustrative of several implementation methods of this disclosure, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of this disclosure, and these modifications and improvements all fall within the protection scope of this disclosure.
