[0003] In related technologies, fabric cleaning machines can only self-clean the suction pipes, and the self-cleaning process is incomplete, making it impossible to self-clean the cleaning brushes. This results in incomplete cleaning of the cleaning brushes, leading to bacterial growth and odor. Utility Model Content

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a cleaning device that can self-clean the cleaning process, thereby making the self-cleaning of the cleaning device more comprehensive and reducing bacterial growth and odor generation.

[0005] The cleaning device according to this utility model includes: a cleaning brush, a suction pipe, and a cleaning cover. The cleaning brush is provided with a spray nozzle and a first air inlet. The suction pipe is connected to the cleaning brush and communicates with the first air inlet. The cleaning cover is detachably installed on the cleaning brush. The cleaning cover and / or the cleaning brush are provided with a second air inlet, which is adapted to communicate with the external environment. When the cleaning cover is installed on the cleaning brush, in the airflow direction, the spray nozzle is located between the first air inlet and the second air inlet, so that the airflow at the second air inlet carries the liquid sprayed from the spray nozzle to the first air inlet.

[0006] Therefore, by placing the spray nozzle between the first and second air inlets, with the second air inlet connected to the outside, the airflow can carry the liquid sprayed from the nozzle through the second air inlet to the first air inlet. This allows the liquid to flow along a smoother path and reduces the flow resistance, enabling the liquid to achieve a higher flow rate with lower energy consumption. Consequently, the self-cleaning of the cleaning equipment can be more comprehensive, and bacterial growth and odor generation can be reduced.

[0007] In some examples of this utility model, the cleaning cover includes: a first cover body and a connecting tube, the first cover body forming a first inner cavity, one end of the connecting tube being connected to the cover body and communicating with the first inner cavity, and the other end of the connecting tube and / or the cleaning brush being provided with a second air inlet; wherein, when the cleaning cover is installed on the cleaning brush, the first inner cavity and the first air inlet are arranged opposite to each other.

[0008] In some examples of this utility model, the cleaning brush includes: a brush head and a brush handle. The brush head is provided with a first air inlet. When the cleaning cover is installed on the cleaning brush, the first inner cavity is disposed opposite to the brush head, and the brush handle is connected to the brush head. The brush head is provided with a spray nozzle, which is disposed opposite to the first inner cavity; or the brush handle is provided with a spray nozzle, which is disposed opposite to the other end of the connecting tube.

[0009] In some examples of this utility model, the other end of the connecting pipe is provided with a guide portion protruding to one side, and the guide portion and the brush handle form a second air inlet.

[0010] In some examples of this utility model, the brush handle is provided with the spray nozzle, and there are two guide portions, which are located on opposite sides of the other end of the connecting tube; wherein, when the cleaning cover is installed on the cleaning brush, the spray nozzle is located between the two guide portions.

[0011] In some examples of this utility model, the cleaning cover further includes a clamping part connected to the other end of the connecting tube, the clamping part forming a clamping groove with an opening, the clamping groove clamping the brush handle when the cleaning cover is installed to the cleaning brush.

[0012] In some examples of this utility model, the cleaning cover further includes: a second cover body, the second cover body being movably connected to the first cover body, the second cover body being selectively disposed inside and outside the first inner cavity, the second cover body forming a second inner cavity, and the first cover body and the second cover body having different sizes and / or shapes.

[0013] In some examples of this utility model, a first inlet communicating with one end of the connecting tube is provided on one side of the outer periphery of the first cover, a second inlet is provided on one side of the outer periphery of the second cover, and the other side of the outer periphery of the second cover is rotatably connected to the other side of the outer periphery of the first cover; wherein, when the second cover is disposed in the first inner cavity, the second inlet is disposed opposite to the first inlet.

[0016] Compared with related technologies, this utility model adopts a method of setting the spray nozzle between the first air inlet and the second air inlet, with the second air inlet connected to the outside. This allows the airflow to carry the liquid sprayed from the spray nozzle through the second air inlet to the first air inlet, thereby allowing the liquid to flow along a smoother path and reducing the flow resistance of the liquid. This enables the liquid to achieve a higher flow rate with lower energy consumption, thus making the self-cleaning of the cleaning equipment more comprehensive and reducing bacterial growth and odor generation.

[0020] 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.

[0021] The following is for reference. Figures 1-6 The present invention describes a cleaning device 100 according to an embodiment of the present invention. For example, the cleaning device 100 may be a fabric cleaning machine, a vacuum cleaner, a steam cleaner, and a carpet cleaning machine, etc.

[0022] like Figures 1-6 As shown, the cleaning device 100 according to this utility model includes: a cleaning brush 10, a suction pipe, and a cleaning cover 20. The cleaning brush 10 is provided with a spray nozzle 11 and a first air inlet 12. The suction pipe is connected to the cleaning brush 10 and communicates with the first air inlet 12. The cleaning cover 20 is detachably installed on the cleaning brush 10. The cleaning cover 20 or the cleaning brush 10 is provided with a second air inlet 21, which is suitable for communicating with the external environment. When the cleaning cover 20 is installed on the cleaning brush 10, in the airflow direction, the spray nozzle 11 is located between the first air inlet 12 and the second air inlet 21, so that the airflow at the second air inlet 21 carries the liquid sprayed from the spray nozzle 11 to the first air inlet 12.

[0023] It is understandable that the cleaning brush 10 is equipped with a spray nozzle 11 and a first air inlet 12. The spray nozzle 11 is located in the middle of the cleaning brush 10, so that the liquid sprayed from the spray nozzle 11 can flow through a certain space and erode the target area. The suction pipe is set in the cleaning brush 10, and the first air inlet 12 is connected to the suction pipe. After the liquid cleans a part of the cleaning brush 10, it enters the suction pipe through the first air inlet 12. The cleaning cover 20 can be installed or removed from the cleaning brush 10. When the cleaning brush 10 needs to self-clean, the cleaning cover 20 is installed on the cleaning brush 10. When the cleaning brush 10 does not need to self-clean, the cleaning cover 20 is removed from the cleaning brush 10, thereby ensuring the normal use of the cleaning brush 10 and its self-cleaning function.

[0024] The cleaning cover 20 is provided with a second air inlet 21, which is located close to the spray nozzle 11 and is connected to the external environment. This allows outside air to flow into the cleaning cover 20 through the second air inlet 21 when the spray nozzle 11 sprays liquid, and pushes away the liquid flowing out of the spray nozzle 11, so that the cleaning cover 20 can clean the cleaning brush 10 more thoroughly.

[0025] Specifically, when the cleaning brush 10 needs to self-clean, the cleaning cover 20 is installed on the cleaning brush 10. At this time, the spray nozzle 11 is located between the first air inlet 12 and the second air inlet 21. When the spray nozzle 11 sprays liquid, the outside air flows into the cleaning cover 20 through the second air inlet 21. The airflow at the second air inlet 21 carries the liquid sprayed from the spray nozzle 11 to clean part of the cleaning brush 10, and then flows to the first air inlet 12. Finally, the used liquid flows out through the suction pipe. This simplifies the self-cleaning process of the cleaning brush 10 and avoids the tedious manual rinsing of the cleaning brush 10, thereby ensuring the thorough self-cleaning of the cleaning brush 10 and reducing bacterial growth and odor.

[0026] Therefore, by placing the spray nozzle 11 between the first air inlet 12 and the second air inlet 21, with the second air inlet 21 connected to the outside, the airflow can carry the liquid sprayed from the spray nozzle 11 through the second air inlet 21 to the first air inlet 12. This allows the liquid to flow along a smoother path and reduces the flow resistance of the liquid, enabling the liquid to achieve a higher flow rate with lower energy consumption. Consequently, the self-cleaning of the cleaning device 100 can be more comprehensive, and the growth of bacteria and the generation of odors can be reduced.

[0027] In addition, such as Figure 1 , Figure 2 and Figure 5 As shown, the cleaning cover 20 includes: a first cover body 22 and a connecting tube 23. The first cover body 22 forms a first inner cavity 221. One end of the connecting tube 23 is connected to the first cover body 22 and communicates with the first inner cavity 221. The other end of the connecting tube 23 or the cleaning brush 10 is provided with a second air inlet 21. When the cleaning cover 20 is installed on the cleaning brush 10, the first inner cavity 221 and the first air inlet 12 are arranged opposite to each other.

[0028] In other words, the first cover 22 and the connecting pipe 23 constitute the main structure of the cleaning cover 20. The first cover 22 mainly serves as the main load-bearing structural component of the outer contour of the cleaning cover 20. The first cover 22 has a first inner cavity 221 inside, which is conducive to forming a relatively closed rinsing and cleaning environment when the first cover 22 and the cleaning brush 10 are connected, thereby preventing liquid leakage and ensuring the self-cleaning effect of the cleaning brush 10. The connecting pipe 23 is located downstream of the first cover 22. The end of the connecting pipe 23 away from the first cover 22 is provided with a second air inlet 21. The second air inlet 21 is adjacent to the liquid spray port 11, so that outside air can pass through the second air inlet 21, thereby affecting the flow direction and flow rate of the liquid.

[0029] The cleaning cover 20 is installed behind the cleaning brush 10. The first inner cavity 221 is positioned opposite to the first air inlet 12. When the spray nozzle 11 sprays liquid, outside air flows into the connecting pipe 23 through the second air inlet 21. The airflow at the second air inlet 21 carries the liquid sprayed from the spray nozzle 11 to clean part of the cleaning brush 10 in the first inner cavity 221, and then flows to the first air inlet 12. Finally, the used liquid flows out through the suction pipe. This simplifies the self-cleaning process of the cleaning brush 10 and ensures the rinsing effect of the cleaning brush 10. It also avoids the tediousness of manually rinsing the cleaning brush 10, thus ensuring the thorough self-cleaning of the cleaning brush 10 and reducing bacterial growth and odor.

[0030] For example, the connecting pipe 23 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.

[0031] In addition, such as Figures 1-4 As shown, the cleaning brush 10 includes a brush head 13 and a brush handle 14. The brush head 13 is provided with a first air inlet 12. When the cleaning cover 20 is installed on the cleaning brush 10, the first inner cavity 221 is disposed opposite to the brush head 13, and the brush handle 14 is connected to the brush head 13. The brush head 13 is provided with a spray nozzle 11, which is disposed opposite to the first inner cavity 221; or the brush handle 14 is provided with a spray nozzle 11, which is disposed opposite to the other end of the connecting pipe 23.

[0032] It is understandable that the brush head 13 and the brush handle 14 constitute the main structure of the cleaning brush 10. The brush head 13 is located upstream of the brush handle 14, which facilitates the brush head 13 in cleaning the target area. The first air inlet 12 is located on the brush head 13, so that after the liquid cleans the brush head 13, the used liquid flows through the first air inlet 12 to the suction pipe. Moreover, the cleaning cover 20 is installed after the cleaning brush 10, and the first inner cavity 221 is installed opposite to the brush head 13. This creates a certain space between the cleaning cover 20 and the brush head 13, and the liquid cleans the brush head 13 in this space, thereby ensuring the cleanliness of the brush head 13 and the flow away of the used liquid, thus improving the self-cleaning convenience of the cleaning equipment 100.

[0033] Optionally, the spray nozzle 11 can be located on the brush head 13 or the brush handle 14. The spray nozzle 11 can be positioned between the first air inlet 12 and the second air inlet 21. If the spray nozzle 11 is located on the brush head 13, both the spray nozzle 11 and the first air inlet 12 correspond to the first inner cavity 221. This allows outside air to flow into the connecting pipe 23 through the second air inlet 21 when the spray nozzle 11 sprays liquid. The airflow at the second air inlet 21 passes through the spray nozzle 11, and the airflow carries the liquid sprayed from the spray nozzle 11 to clean a portion of the cleaning brush 10 in the first cavity before flowing to the first air inlet 12. Finally, the used liquid flows out through the suction pipe. If the spray nozzle 11 is located in the middle of the brush handle 14, and the spray nozzle 11 is positioned between the first air inlet 12 and the second air inlet 21, the spray nozzle 11 can be positioned between the first air inlet 12 and the second air inlet 21. The liquid outlet 11 is arranged opposite to the downstream of the connecting pipe 23, so that the liquid outlet 11 is adjacent to the second air inlet 21. When the liquid outlet 11 sprays liquid, the outside air flows into the connecting pipe 23 through the second air inlet 21 and then passes through the liquid outlet 11. The airflow carries the liquid sprayed from the liquid outlet 11 to clean part of the cleaning brush 10 in the first cavity, and then flows to the first air inlet 12. Finally, the used liquid flows out through the suction pipe. This simplifies the self-cleaning process of the cleaning brush 10 and ensures the rinsing effect of the cleaning brush 10. It also avoids the tediousness of manually rinsing the cleaning brush 10, thereby ensuring the thorough self-cleaning of the cleaning brush 10 and reducing bacterial growth and odor.

[0034] In addition, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the other end of the connecting pipe 23 is provided with a guide portion 231 protruding to one side, and a second air inlet 21 is formed between the guide portion 231 and the brush handle 14.

[0035] In other words, the connecting pipe 23 has a guide section 231 protruding outward along its width at the other end away from the first cover 22. The gap between the guide section 231 and the brush handle 14 forms a second air inlet 21. The guide section 231 can be used to guide external air in, so that the guide section 231 can work with related structures (such as a suction device) to form a suction force on the liquid and air, thereby increasing the flushing force of the liquid on the brush head 13 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 the liquid and air, preventing the liquid flushing the brush head 13 and the suction pipe from flowing out to the outside through the guide section 231, avoiding further cleaning burden on the user.

[0036] In particular, such as Figure 1 -and Figure 6 As shown, the brush handle 14 is provided with a spray nozzle 11 and two guide parts 231, which are located on opposite sides of the other end of the connecting tube 23; wherein, when the cleaning cover 20 is installed on the cleaning brush 10, the spray nozzle 11 is located between the two guide parts 231.

[0037] Understandably, the two guide sections 231 are located on both sides of the connecting pipe 23, and the two guide sections 231 protrude relatively far apart. When the cleaning cover 20 is installed on the cleaning brush 10, the airflow passes through the two guide sections 231 and the spray nozzle 11. This allows the airflow to carry the liquid more stably, thereby ensuring the stability of the liquid flow, increasing the flushing force of the liquid on the brush head 13 and the suction pipe, and effectively reducing the blockage of the suction pipe, bacterial growth and odor generation.

[0038] In addition, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the cleaning cover 20 also includes a clamping part 24, which is connected to the other end of the connecting tube 23. The clamping part 24 has a clamping groove 241 with an opening. When the cleaning cover 20 is installed on the cleaning brush 10, the clamping groove 241 clamps the brush handle 14.

[0039] In other words, the other end of the connecting tube 23 away from the first cover 22 is connected to the clamping part 24. The clamping part 24 is formed with an open clamping groove 241, which makes it easy for the clamping part 24 to clamp on the brush handle 14, thereby ensuring the reliability of the connection between the cleaning cover 20 and the cleaning brush 10. It also allows the cleaning cover 20 and the cleaning brush 10 to remain relatively stable when the cleaning cover 20 cleans the cleaning brush 10, thereby ensuring the normal operation of the self-cleaning work of the cleaning equipment 100.

[0040] In addition, such as Figure 2 and Figure 6As shown, the cleaning cover 20 also includes a second cover 25, which is movably connected to the first cover 22. The second cover 25 can be selectively disposed inside or outside the first inner cavity 221. The second cover 25 forms a second inner cavity 251. The first cover 22 and the second cover 25 have different sizes or shapes.

[0041] Understandably, the second cover 25 can be movably connected to the first cover 22, where the first cover 22 is larger than the second cover 25. When the user needs to adapt to a larger brush head 13, the second cover 25 can move to the side of the first cover 22 away from the first inner cavity 221, or move into the first inner cavity 221. This ensures that the liquid cleans the larger brush head 13. The second cover 25 has a second inner cavity 251. When the user needs to adapt to a smaller brush head 13, the second cover 25 moves to the side of the brush head 13, with the second inner cavity 251 opposite to the brush head 13, and the first cover 22 away from the brush head 13. This ensures that the liquid cleans the smaller brush head 13. The second cover 25 not only strengthens the structure of the first cover 22, but also allows different sizes or shapes of second covers 25 to adapt to different brush heads 13, thereby improving the efficiency and stability of the self-cleaning operation of the cleaning device 100.

[0042] Among them, such as Figure 5 and Figure 6 As shown, the outer periphery of the first cover 22 is provided with a first inlet 222 communicating with one end of the connecting pipe 23, and the outer periphery of the second cover 25 is provided with a second inlet 252. The other side of the outer periphery of the second cover 25 is rotatably connected to the other side of the outer periphery of the first cover 22. When the second cover 25 is disposed in the first inner cavity 221, the second inlet 252 is disposed opposite to the first inlet 222.

[0043] In other words, the first cover 22 and the second cover 25 are respectively provided with a first inlet 222 and a second inlet 252 on the side facing the second air inlet 21 or the liquid spraying port 11. The first inlet 222 is connected to the connecting pipe 23. This allows the liquid sprayed from the liquid spraying port 11 to be driven by the gas entering through the second air inlet 21 when the first cover 22 is placed on the brush head 13, flow through the connecting pipe 23, and then enter the first inner cavity 221 through the first inlet 222, thus facilitating the cleaning of the brush head 13 by the liquid. Alternatively, after the second cover 25 is placed on the first inner cavity 221, the second inlet 252 corresponds to the first inlet 222. This allows the liquid sprayed from the liquid spraying port 11 to be driven by the gas entering through the second air inlet 21 when the second cover 25 is placed on the brush head 13, flow through the connecting pipe 23, and then enter the second inner cavity 251 through the first inlet 222 and the second inlet 252, thus facilitating the cleaning of the brush head 13 by the liquid. This ensures the thorough self-cleaning of the cleaning equipment 100, as well as the self-cleaning efficiency and improved hygiene.

[0044] Specifically, the inner wall of the first inner cavity 221 is provided with a first flow guiding structure, and the inner wall of the second inner cavity 251 is provided with a second flow guiding structure.

[0045] Understandably, the first and second flow guiding structures have the effect of guiding the liquid and optimizing the flow path of the liquid and gas. This allows the first and second flow guiding structures to guide the liquid to flow along a smoother path, reducing flow resistance and enabling the liquid to achieve a higher flow rate with lower energy consumption. It also helps to maintain the continuity and stability of the liquid, avoid the formation of turbulence and stagnation areas, thereby enhancing the fluidity of the liquid and improving the self-cleaning efficiency of the cleaning equipment 100.

[0046] In addition, such as Figure 3 and Figure 4 As shown, the cleaning brush 10 includes a brush head 13, which is provided with a first air inlet 12 and a cleaning section 15. The first air inlet 12 is located on the side of the cleaning section 15 near the spray nozzle 11, or the first air inlet 12 is located on the side of the cleaning section 15 away from the spray nozzle 11.

[0047] In other words, the first air inlet 12 and the cleaning part 15 are located on the brush head 13. The first air inlet 12 is located on the side of the cleaning part 15 that is close to or far from the spray nozzle 11. When the cleaning cover 20 is not connected to the cleaning brush 10, the user can use the cleaning part 15 to clean the target location. When the cleaning part 15 needs to be cleaned, the cleaning cover 20 is installed on the cleaning brush 10. The liquid sprayed from the spray nozzle 11 flows into the first inner cavity 221 or the second inner cavity 251 through the airflow. After cleaning the cleaning part 15, it flows into the suction pipe from the first air inlet 12, thereby enabling the cleaning device 100 to complete self-cleaning.

[0048] The cleaning process of the self-cleaning device 100 is described in detail below: For example, the cleaning equipment 100 can be a fabric cleaning machine. The handle of the brush head 13 or the brush head 13 is provided with a spray nozzle 11. After the cleaning cover 20 is installed in conjunction with the brush head 13, it can completely cover the spray nozzle 11. The spray nozzle 11 is located between the second air inlet 21 (such as the guide section 231) and the first air inlet 12, forming a closed rinsing environment.

[0049] When the cleaning cover 20 is installed on the brush head 13 and the self-cleaning function is activated, the fan and water pump of the fabric cleaning machine work together: the water pump sprays cleaning fluid from the spray nozzle 11 into the interior of the cleaning cover 20, then the fan operates, causing external air to flow in from the second air inlet 21, driving the cleaning fluid to flow. At this time, the mixed airflow and cleaning fluid enter the first inner cavity 221 or the second inner cavity 251 to clean the cleaning section 15, and then flow out from the first air inlet 12, finally entering the suction pipe; the cleaning fluid, driven by the negative pressure suction airflow, passes through the cleaning section 15 on the brush head 13 and enters the suction pipe, simultaneously flushing and cleaning the cleaning section 15 and the suction pipe. In summary, through the above structural design, automatic circulating rinsing can be achieved, effectively removing residual stains in the cleaning section 15 and the suction pipe, improving cleaning efficiency and hygiene, and also extending the service life of the fabric cleaning machine and reducing maintenance costs.
