Description

Technical Field

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

[0002] Most fabric cleaning machines currently available have two water tanks: one for clean water and the other for wastewater. However, during the wastewater recycling process, the wastewater contains many impurities that easily adhere to the brush bristles and the inner walls of the wastewater pipes. As a result, after long-term use, the brush bristles and the inside of the wastewater pipes will accumulate a large amount of dirt, hair, or residual cleaning solution, leading to blockages or bacterial growth.

[0003] In related technologies, fabric cleaning machines are typically equipped with various brush heads of different sizes to adapt to different cleaning scenarios (e.g., wide brush heads for large-area cleaning, narrow brush heads for crevices cleaning), and are also equipped with self-cleaning devices. However, the self-cleaning devices require the brush heads to be removed during use, which is inconvenient, and they can only self-clean the suction pipe, not the bristles on brush heads of different sizes. Therefore, the existing technology has considerable room for improvement. Utility Model Content

[0031] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0032] The following is for reference. Figures 1-7 The self-cleaning component 100 according to an embodiment of the present utility model can be adapted to accessories 200 of different sizes and shapes. Users only need to replace the corresponding cleaning cover 10 to complete the cleaning, thereby avoiding the problem of incomplete cleaning caused by different accessories 200.

[0033] Combination Figures 1-7 As shown, the self-cleaning assembly 100 according to the first aspect of the present invention includes a plurality of cleaning covers 10. The cleaning cover 10 can be adapted to the accessory 200, and clean water can be used to directly rinse the accessory 200 inside the cleaning cover 10, thereby achieving the rinsing and self-cleaning operation of the accessory 200 without removing it.

[0034] Specifically, multiple cleaning covers 10 are connected together, and each cleaning cover 10 has an open accessory docking cavity 11 for docking with an accessory 200 to clean the accessory 200. The multiple accessory docking cavities 11 have different sizes and / or shapes to accommodate accessories 200 of different sizes and / or shapes. For example, the accessory 200 can be a brush head of different sizes and / or shapes.

[0035] Specifically, multiple cleaning covers 10 can be connected to each other as a whole, which can improve storage efficiency and ease of use; the open accessory docking cavity 11 is conducive to docking with the brush head, and the accessory docking cavity 11 forms a certain internal space, which can provide a rinsing environment for the bristles on the brush head, thereby achieving the rinsing and cleaning effect of the brush head.

[0036] Furthermore, since cleaning equipment is typically equipped with a variety of brush heads of different sizes and / or shapes to adapt to different cleaning scenarios (such as wide brush heads for large-area cleaning and narrow brush heads for crevices cleaning), the embodiments in this case adapt to a variety of brush heads of different sizes and / or shapes by providing multiple accessory docking cavities 11 of different sizes and / or shapes. This enables the self-cleaning component 100 to adapt to a variety of brush heads, avoiding the problem of incomplete cleaning caused by different brush head sizes and / or shapes, thereby improving the versatility and practicality of the self-cleaning component 100 and thus improving the user experience.

[0037] Clean water can be sprayed from the nozzle of the cleaning device into the accessory docking chamber 11. The accessory docking chamber 11 provides a relatively enclosed rinsing environment for the brush bristles. After rinsing the bristles, the water in the accessory docking chamber 11 is drawn into the suction pipe through the suction port on the brush head, continuing to rinse the suction pipe. This arrangement allows for rinsing of both the brush head and the suction pipe without removing the brush head, achieving a complete cleaning process. This effectively reduces the probability of bacterial growth, pipe blockage, and odor generation, avoiding the burden of manual disassembly and cleaning for users. Furthermore, the structure is simple and easy to operate.

[0038] Therefore, by setting up this self-cleaning component 100, it can be adapted to accessories 200 of different sizes and shapes. Users only need to replace the corresponding cleaning cover 10 to complete the cleaning, thereby avoiding the problem of incomplete cleaning caused by different accessories 200. Moreover, the structure is simple and the operation is convenient.

[0039] Alternatively, combined Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, multiple cleaning covers 10 are rotatably connected to each other. This allows the multiple cleaning covers 10 to be connected as a whole, and also makes it convenient for users to switch between cleaning covers 10 of corresponding size and / or shape by rotating the cleaning covers 10 according to the required accessories 200, thereby improving the ease of operation and storage effect.

[0040] Alternatively, multiple cleaning covers 10 can be detachably connected to each other. This arrangement allows for flexible assembly and disassembly of the multiple cleaning covers 10, thereby improving storage and usage efficiency. It also enables individual maintenance and replacement, thus improving ease of assembly and disassembly and cost-effectiveness.

[0041] Specifically, in combination Figures 1-6 As shown, the plurality of cleaning covers 10 include at least a first cleaning cover 12 and a second cleaning cover 13. The first cleaning cover 12 is provided with a first accessory docking cavity 121. The second cleaning cover 13 is movably connected to the first cleaning cover 12. The second cleaning cover 13 can be selectively disposed inside or outside the first accessory docking cavity 121.

[0042] Understandably, the second cleaning cover 13 is movably connected to the first cleaning cover 12. When the user needs to adapt to a larger brush head, the second cleaning cover 13 can be moved to the outside of the first accessory docking cavity 121. This facilitates docking of the first accessory docking cavity 121 with the corresponding brush head, avoiding structural interference caused by the second cleaning cover 13. When the user needs to adapt to a smaller brush head, the first cleaning cover 12 can be moved to the inside of the first accessory docking cavity 121. This allows the accessory docking cavity 11 of the second cleaning cover 13 to dock with the corresponding brush head, while also providing a certain degree of structural reinforcement to the second cleaning cover 13, thereby improving the stability of the self-cleaning operation.

[0043] Furthermore, combined Figures 4-7As shown, the first cleaning cover 12 includes a first cover body 122 and a connecting tube 123. The first cover body 122 is provided with a first accessory docking cavity 121. A first inlet 1221 is provided on one side of the outer periphery of the first cover body 122. One end of the connecting tube 123 is connected to one side of the outer periphery of the first cover body 122, and one end of the connecting tube 123 is connected to the first inlet 1221. The other end of the connecting tube 123 is used for liquid inlet.

[0044] In other words, the first cover 122 mainly serves as the main load-bearing structural component of the outer contour of the first cleaning cover 12. The first cover 122 has a first accessory docking cavity 121 inside. This allows the first accessory docking cavity 121 to form a relatively closed rinsing and cleaning environment when docking with the corresponding accessory 200, thereby preventing water leakage and ensuring the self-cleaning effect of the accessory 200. The connecting pipe 123 and the first cover 122 are connected as a solid whole. The outer circumference of the first cover 122 has a first inlet 1221 that allows external fluids (such as clean water or external air) to enter. One end of the connecting pipe 123 is connected to the first inlet 1221, and the other end of the connecting pipe 123 can be used for liquid inlet. In this way, external liquids can be smoothly guided into the first accessory docking cavity 121 through the connecting pipe 123, which is conducive to achieving the effect of rinsing the accessory 200.

[0045] Specifically, in combination Figure 4 and Figure 5 As shown, a second inlet 131 is provided on one side of the outer periphery of the second cleaning cover 13, and the other side of the outer periphery of the second cleaning cover 13 is rotatably connected to the other side of the outer periphery of the first cover body 122; wherein, when the second cleaning cover 13 is disposed in the first accessory docking cavity 121, the second inlet 131 is disposed opposite to the first inlet 1221.

[0046] It is understood that the outer side of the second cleaning cover 13 is provided with a second inlet 131 that allows external fluids (such as clean water or outside air) to enter. When the user needs to adapt to a smaller brush head, the second cleaning cover 13 is rotated into the first accessory docking cavity 121. The second inlet 131 of the second cleaning cover 13 is opposite to and connected to the first inlet 1221 of the first cleaning cover 12. This facilitates the smooth flow of water through the flow path of the connecting pipe 123-first inlet 1221-second inlet 131 into the accessory docking cavity 11 corresponding to the second cover, thereby helping to achieve a self-cleaning effect on the accessory 200 that is adapted to the second cleaning cover 13.

[0047] Furthermore, combined Figure 5 and Figure 7As shown, a snap-fit ​​plate 132 is provided on one side of the outer periphery of the second cleaning cover 13. When the second cleaning cover 13 is placed in the first accessory docking cavity 121, the snap-fit ​​plate 132 engages with the wall of one end of the connecting pipe 123.

[0048] As described above, the second cleaning cover 13 and the connecting pipe 123 are connected into a strong and stable whole through the snap-fit ​​plate 132 and the wall of one end of the connecting pipe 123. Compared with other connection methods (such as screw connection, adhesive connection, etc.), the snap-fit ​​connection does not require additional parts to connect the second cleaning cover 13 and the connecting pipe 123 into a whole, avoiding unnecessary material consumption. It can also provide sufficient holding force to ensure that the two will not loosen or fall off during use. Moreover, the snap-fit ​​connection structure is simple, reliable, and has quick and convenient disassembly and installation functions (that is, it can realize the quick connection and separation of the second cleaning cover 13 and the connecting pipe 123), which can effectively reduce the time and cost required for maintenance, replacement and switching of use status.

[0049] The snap-fit ​​connection can also effectively ensure the accuracy of the relative position between the second cleaning cover 13 and the connecting tube 123, that is, ensure that the liquid in the connecting tube 123 can flow precisely into the accessory docking cavity 11 corresponding to the second cleaning cover 13, thereby ensuring the reliability and stability of the self-cleaning operation.

[0050] Specifically, in combination Figures 4-6 As shown, the other end of the connecting pipe 123 is provided with a guide portion 1231 protruding toward the side of the first cover 122, and the guide portion 1231 is used to guide the gas.

[0051] Understandably, the connecting pipe 123 has a guide portion 1231 protruding outward along its width at the other end away from the first cover 122. The guide portion 1231 can be used to guide external air in, so that the guide portion 1231 can work with related structures (such as a suction device) to form a suction force on clean water and air, thereby increasing the flushing force of clean water on the brush bristles and the suction pipe, effectively reducing the probability of blockage of the suction pipe, bacterial growth and odor generation. On the other hand, it can also form a forced flow effect on clean water and air, preventing the clean water flushing the brush bristles and the suction pipe from flowing out to the outside through the guide portion 1231, thus avoiding further cleaning burden on the user.

[0052] Furthermore, combined Figures 3-7As shown, the connecting pipe 123 is constructed as an arc-shaped pipe. Compared with the design of a right-angle turn, the arc-shaped pipe can provide a smoother flow path, reduce the frictional resistance and turbulence encountered by the fluid when it passes through, thereby improving the flow efficiency. It can also prevent cavitation caused by abrupt angle changes, thereby maintaining a stable pressure distribution. Furthermore, in a limited space, especially when it is necessary to bypass obstacles, the arc-shaped pipe can provide greater flexibility to adjust its direction to adapt to complex layout requirements.

[0053] Specifically, in combination Figures 4-6 As shown, the first cleaning cover 12 also includes a clamping part 124, which is connected to the other end of the connecting tube 123. The clamping part 124 has a clamping groove 1242 with an opening 1241, which is used to clamp the accessory 200.

[0054] It is understood that the other end of the connecting tube 123 is connected to the clamping part 124, and the clamping part 124 is formed with a clamping groove 1242 with an opening 1241, so that the clamping part can be clamped on the accessory 200 (such as the handle or pipe of the brush head), thereby ensuring the reliability of the connection between the self-cleaning component 100 and the accessory 200, and thus ensuring the normal operation of the self-cleaning work of the accessory 200.

[0055] According to some optional embodiments of the present invention, the inner wall of the accessory docking cavity 11 is provided with a flow guiding structure. This arrangement allows the accessory docking cavity 11 to have a flow guiding effect on the clean water inside, thereby guiding the fluid to flow along a smoother path, reducing flow resistance, enabling the fluid to achieve a higher flow rate with lower energy consumption, and also helping to maintain the continuity and stability of the fluid, avoiding the formation of turbulence and stagnation areas, thereby enhancing the fluidity and improving the self-cleaning efficiency of the accessory 200.

[0056] The cleaning device according to the second aspect of the present invention includes a plurality of accessories 200 and the self-cleaning component 100 of the above embodiment, wherein the accessory docking cavity 11 of each cleaning cover 10 is connected to at least one accessory 200.

[0057] Specifically, the cleaning equipment includes multiple accessories 200 (such as wide brush heads for large-area cleaning and narrow brush heads for crevices cleaning), which can adapt to different cleaning scenarios, thereby improving the cleaning versatility and practicality of the cleaning equipment; and the accessory docking cavity 11 of each cleaning cover 10 can be docked with at least one accessory 200, so that the self-cleaning component 100 can be adapted to different accessories 200, thereby improving the versatility of the self-cleaning component 100 and thus improving the market competitiveness of the cleaning equipment.

[0058] The cleaning process of the self-cleaning component 100 is described in detail below:

[0059] For example, the cleaning equipment can be a fabric cleaning machine. The brush head handle or brush head has a spray nozzle. After the self-cleaning cover 10 is installed and connected to the brush head, it can completely cover the spray nozzle. The spray nozzle is located between the self-cleaning air inlet (such as the guide part 1231) and the brush head air inlet, forming a closed rinsing environment. When the self-cleaning cover 10 is installed on the brush head and the self-cleaning function is activated, the fan and water pump of the fabric cleaning machine work together: the water pump sprays the cleaning liquid from the spray nozzle and enters the interior of the self-cleaning cover 10; the fan operates, causing external air to flow in from the self-cleaning air inlet and driving the cleaning liquid to flow; the mixed airflow and cleaning liquid flow out from the brush head air inlet and enter the suction pipe; the cleaning liquid, driven by the negative pressure suction airflow, enters the suction pipe through the bristle opening on the brush head, simultaneously rinsing and cleaning the bristles and the suction pipe. In summary, the above structural design enables automatic circulating rinsing, effectively removing residual stains from the brush bristles and suction pipes, improving cleaning efficiency and hygiene, extending the service life of the fabric cleaning machine, and reducing maintenance costs.
