Abstract
Description
[0001] This application is a divisional application of the invention application entitled "Storage Box, Cleaning Equipment and Control Method", with parent application number "202210852541.1" and parent application date of July 19, 2022. Technical Field
[0002] This application relates to the field of cleaning equipment technology, and more specifically to a cleaning system. Background Technology
[0003] Cleaning equipment such as floor scrubbers and cleaning machines with cleaning functions facilitates cleaning work for users and brings many conveniences, thus gaining widespread use. Cleaning equipment typically has a self-cleaning function to clean its cleaning brush heads. However, currently available portable cleaning equipment, such as fabric cleaning machines, can only clean the internal pipes and cannot perform a comprehensive and thorough cleaning of the cleaning brush heads, both inside and out. Summary of the Invention
[0004] This application provides a cleaning system that facilitates comprehensive and thorough cleaning of accessory brushes and reduces the risk of residual cleaning fluid leakage.
[0005] This application provides a cleaning system, including: A portable cleaning device includes an accessory brush and a pipe connecting the portable cleaning device and the accessory brush. The accessory brush includes a handle for a user to hold, which moves the accessory brush across the surface to be cleaned. A self-cleaning button is provided on the handle. A storage box has a storage cavity and an opening communicating with the storage cavity. The bottom of the storage cavity and the opening are positioned opposite each other. An accessory brush can be inserted into the storage cavity through the opening and facing the bottom. When the accessory brush is stored in the storage cavity, the self-cleaning button is positioned upwards. When the accessory brush is stored in the storage cavity, the portable cleaning device is configured to trigger a self-cleaning function via a self-cleaning button, the accessory brush outputs cleaning fluid to the storage cavity, and the cleaning fluid in the storage cavity is recycled back to the portable cleaning device.
[0006] In one embodiment of this application, the opening is located above the bottom, and the accessory brush is inserted into the storage cavity through the opening and facing downwards.
[0007] In one embodiment of this application, the portable cleaning device further includes: A sensor is provided on the accessory brush and is used to detect whether the accessory brush has reached a set position in the storage box, so that when the accessory brush reaches the set position, the user can trigger the self-cleaning function of the portable cleaning device through the self-cleaning button.
[0008] In one embodiment of this application, when the self-cleaning function is triggered, the accessory brush outputs cleaning fluid into the storage cavity, so that the accessory brush is immersed in the cleaning fluid in the storage cavity for cleaning.
[0009] In one embodiment of this application, after the accessory brush has finished cleaning by immersing itself in the cleaning fluid in the storage cavity, the accessory brush returns the dirty cleaning fluid to the portable cleaning device.
[0010] In one embodiment of this application, the accessory brush further includes a main body and a connecting part. The main body is connected to the handle part through the connecting part, and when the accessory brush is stored in the storage cavity, at least a portion of the main body is embedded in the storage cavity; the self-cleaning button is located at the end of the handle part away from the connecting part.
[0011] In one embodiment of this application, the storage box is further provided with a support surface; the support surface includes a first support surface located at the bottom and a second support surface located at the opening; When the accessory brush is stored in the storage cavity, the main body is supported on the first support surface, and the connecting part is supported on the second support surface.
[0012] In one embodiment of this application, the front end of the main body has a first abutting surface, and the surface of the connecting part that contacts the second supporting surface is a second abutting surface; when the accessory brush is stored in the storage cavity, the first abutting surface and the first supporting surface are completely fitted together, and the shape of the second abutting surface is adapted to the shape of the second supporting surface.
[0013] In one embodiment of this application, the self-cleaning key has an operating surface for user operation; The portable cleaning device also includes a display screen, which is located at the connecting part and the display surface of the display screen faces away from the main body. The plane where the operation surface is located forms an angle with the plane where the display surface is located, and the angle is between 45° and 135°.
[0014] In one embodiment of this application, the display surface faces the front of the portable cleaning device, and the self-cleaning button is positioned upwards.
[0015] In one embodiment of this application, the main body has a brush head, and when the accessory brush is stored in the storage cavity, the brush head is stored in the storage box; the brush head is provided with a suction nozzle, which is used to absorb cleaning liquid in the storage cavity.
[0016] In one embodiment of this application, the portable cleaning device further includes a brush head release button, which is located on the side of the main body facing the handle, and is used to selectively release the brush head on the main body.
[0017] In one embodiment of this application, the bottom of the receiving cavity and the opening are disposed opposite to each other along a first direction; The portable cleaning device also includes a main mode button and a sub-mode button. The main mode button is located on the side of the handle that is away from the main body, and the sub-mode button is located on the side of the handle that faces the main body. The center of the main mode key and the center of the sub-mode key are on the same plane, and the plane is parallel to the first direction and the relative direction of the main body and the handle. The center of the main mode key is farther away from the connecting part relative to the center of the sub-mode key.
[0018] In one embodiment of this application, the receiving cavity includes a first sub-cavity and a second sub-cavity that are connected to each other; The portion of the accessory brush embedded in the storage cavity is located within the first sub-cavity; When the accessory brush is stored in the storage cavity, the inner wall of the second sub-cavity is away from the accessory brush.
[0019] The beneficial effects of this application are as follows: When the portable cleaning device has a self-cleaning function, the storage cavity, as a container, can hold the accessory brush and the cleaning fluid output by the accessory brush, allowing the accessory brush to be immersed in the cleaning fluid in the storage cavity, which is conducive to a comprehensive and thorough cleaning of the inside and outside of the accessory brush. Afterwards, the accessory brush will collect the dirty cleaning fluid back into the portable cleaning device. When the portable cleaning device has residual cleaning fluid after completing the cleaning work, the residual cleaning fluid flows out from the accessory brush and collects at the bottom of the storage cavity, without leaking to the outside, which can effectively reduce the risk of residual cleaning fluid leakage.
[0020] The self-cleaning button is located on the handle of the attachment brush, at the end furthest from the connector. This design ensures that when the user holds the attachment brush, the button is away from their hand, reducing the risk of accidental activation. Furthermore, since the handle furthest from the connector faces upwards when the attachment brush is stored in the case, the self-cleaning button is also positioned upwards, making it easy for the user to see and operate.

Detailed Implementation
[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to up, down, left, and right in the actual use or working state of the device, specifically the drawing directions in the accompanying drawings.
[0025] This application provides a portable cleaning device and its accessories, including a brush, a storage box, a cleaning system, and a control method, which are described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.
[0026] In existing technologies, cleaning equipment such as traditional floor scrubbers and fabric cleaning machines can be equipped with self-cleaning functions. For traditional floor scrubbers, the self-cleaning function relies on a tray for storage. Specifically, the user places the scrubber on the tray, and the scrubber and tray work together to create a space for water. The scrubber outputs water to clean the brush heads, and the wastewater is then recycled back into the scrubber. However, the trays of traditional floor scrubbers lack convenience, preventing users from carrying the tray while using the machine. For fabric cleaning machines, they can only clean the internal pipes connecting the brush heads, and cannot thoroughly clean the brush heads themselves. Furthermore, the brush heads in fabric cleaning machines usually need to be stored vertically to prevent residual water from leaking out.
[0027] In view of this, embodiments of this application provide a storage box, a cleaning device, and a control method, which can solve the technical problems in the prior art of not being able to thoroughly clean the inside and outside of the cleaning brush head and the easy leakage of residual water in the cleaning brush head to the outside. These are described in detail below.
[0028] Please see Figure 1 , Figure 1 This is an exploded structural diagram of an embodiment of the cleaning system of this application.
[0029] In one embodiment, the cleaning system includes a portable cleaning device 10, which may be a cleaning device such as a fabric cleaning machine. The portable cleaning device 10 has an accessory brush 20, and the user can carry the portable cleaning device 10 and use the accessory brush 20 to clean the surfaces of fabric products and woven materials such as sofas, carpets, and blankets.
[0030] The cleaning system also includes a storage box 30 for storing the accessory brush 20. Specifically, after the user finishes using the accessory brush 20, the accessory brush 20 can be stored in the storage box 30.
[0031] Furthermore, the portable cleaning device 10 also has a connecting structure 16 for connecting the storage box 30, so that the storage box 30 can be carried by the user along with the portable cleaning device 10. Optionally, the connection structure 16 and the storage box 30 can be detachable in the form of slot engagement, snap engagement, magnetic engagement, etc. Of course, the connection structure 16 and the storage box 30 can also be directly fixed together. Figure 1 The example illustrates the slotted engagement between the connecting structure 16 and the storage box 30, for illustrative purposes only and not intended to be limiting.
[0032] Furthermore, the portable cleaning device 10 also includes a charging tray 17. The charging tray 17 is connected to an external power source, or the charging tray 17 itself is equipped with a power source. The portable cleaning device 10 is placed on the charging tray 17 for charging. Of course, in other embodiments of this application, the portable cleaning device 10 may also be equipped with a charging cable, and the portable cleaning device 10 is connected to an external power source for charging via the charging cable.
[0033] Please refer to the following: Figure 2 and Figure 3 , Figure 2 This is a cross-sectional structural diagram of an embodiment of the storage box of this application. Figure 3 This is a schematic diagram of the structure of an embodiment of the storage box of this application. The storage box 30 of this application embodiment will be described below.
[0034] In one embodiment, the storage box 30 has a storage cavity 31 and an opening 32. The opening 32 communicates with the storage cavity 31, and the bottom 311 of the storage cavity 31 and the opening 32 are disposed opposite to each other. When the accessory brush 20 is stored in the storage box 30, the accessory brush 20 is inserted into the storage cavity 31 through the opening 32 and toward the bottom 311 of the storage cavity 31.
[0035] Furthermore, when the storage box 30 is assembled with the portable cleaning device 10 and stores the accessory brush 20, the vertical opening 32 is positioned above the bottom 311 of the storage cavity 31. The accessory brush 20 is inserted into the storage cavity 31 through the opening 32 and vertically downwards, at which point the accessory brush 20 is stored downwards in the storage box 30. In this way, when the accessory brush 20 is stored in the storage cavity 31, the cleaning fluid flows out from the accessory brush 20 under the influence of gravity and collects at the bottom 311 of the storage cavity 31. When the portable cleaning device 10 has a self-cleaning function, the accessory brush 20 outputs cleaning fluid to the storage cavity 31. The cleaning fluid also flows out of the accessory brush 20 under the action of gravity, so that the accessory brush 20 is immersed in the cleaning fluid in the storage cavity 31 for cleaning. Afterwards, the accessory brush 20 collects the dirty cleaning fluid back into the portable cleaning device 10. As for the case where there is residual cleaning fluid in the accessory brush 20 and the pipe connected to the accessory brush 20 after the portable cleaning device 10 has completed the cleaning work, the residual cleaning fluid will at least flow out of the accessory brush 20 under the action of gravity.
[0036] In the above manner, when the portable cleaning device 10 has a self-cleaning function, the storage cavity 31, as a container, can hold the accessory brush 20 and the cleaning fluid output by the accessory brush 20, so that the accessory brush 20 is immersed in the cleaning fluid in the storage cavity 31, which is conducive to a comprehensive and thorough cleaning of the inside and outside of the accessory brush 20; and when the portable cleaning device 10 has residual cleaning fluid after completing the cleaning work, the residual cleaning fluid flows out from the accessory brush 20 and collects at the bottom 311 of the storage cavity 31, without leaking to the outside, which can effectively reduce the risk of residual cleaning fluid leakage.
[0037] Furthermore, in existing fabric cleaning machines, the cleaning brush head 241 is stored vertically upwards, and the residual cleaning liquid in the brush head 241 is not drained. When the user removes the cleaning brush head 241, there is still a risk of leakage of the residual cleaning liquid. However, in this embodiment, the accessory brush 20 is placed downwards in the storage box 30, and the residual cleaning liquid is drained from the accessory brush 20 under the influence of gravity. Therefore, when the user removes the accessory brush 20 from the storage box 30, the risk of cleaning liquid leakage from the accessory brush 20 is greatly reduced.
[0038] It should be noted that the vertical opening 32 can be located directly above or diagonally above the bottom 311 of the storage cavity 31. The accessory brush 20 can be inserted into the storage cavity 31 with its orientation strictly vertically downwards, or it can be inserted into the storage cavity 31 with its orientation approximately vertically downwards. The direction of movement of the accessory brush 20 into the storage cavity 31 can be at a certain angle to the vertical direction. Residual cleaning fluid flowing from the accessory brush 20 into the storage box 30 can be recovered during the self-cleaning process of the accessory brush 20, or the user can remove the storage box 30 for cleaning; this is not limited. Furthermore, the cleaning fluid can be water, detergent, or a mixture of water and detergent; this is not limited.
[0039] Please refer to the following: Figures 4a-4b and Figure 5 , Figures 4a-4b This is a structural schematic diagram of one embodiment of the brush in the appendix to this application. Figure 5 This is a structural diagram of an embodiment of a brush stored in a storage box, as shown in the appendix of this application.
[0040] In one embodiment, the storage box 30 is further provided with a support surface 33. When the accessory brush 20 is stored in the storage cavity 31, the accessory brush 20 is supported on the support surface 33 at least under the action of gravity, so that the accessory brush 20 is reliably and stably stored in the storage box 30, and the accessory brush 20 is prevented from shaking in the storage box 30 as much as possible.
[0041] In one embodiment, the support surface 33 includes a first support surface 331. The first support surface 331 is located at the bottom 311 of the receiving cavity 31. When the accessory brush 20 is received in the receiving cavity 31, the accessory brush 20 is supported on the first support surface 331. Specifically, the front end of the accessory brush 20 has a first abutment surface 21. When the accessory brush 20 is received in the receiving cavity 31, the first abutment surface 21 of the accessory brush 20 contacts the first support surface 331, thereby supporting the accessory brush 20 on the first support surface 331.
[0042] Furthermore, when the accessory brush 20 is stored in the storage cavity 31, the first contact surface 21 and the first support surface 331 are completely in contact, so that the first support surface 331 can reliably and stably support the accessory brush 20, which further facilitates the reliable and stable storage of the accessory brush 20 in the storage box 30.
[0043] Furthermore, the front end of the accessory brush 20 also has a suction nozzle 22, which is used to absorb the cleaning fluid in the storage cavity 31. Specifically, if the portable cleaning device 10 has a self-cleaning function, the accessory brush 20 outputs cleaning fluid into the storage cavity 31, allowing the accessory brush 20 to be immersed in the cleaning fluid in the storage cavity 31 for cleaning. Afterwards, the accessory brush 20 collects the dirty cleaning fluid back into the portable cleaning device 10 through the suction nozzle 22. If there is residual cleaning fluid after the portable cleaning device 10 has completed the cleaning work, the residual cleaning fluid will flow out of the accessory brush 20 at least under the action of gravity. Afterwards, the accessory brush 20 collects the cleaning fluid in the storage cavity 31 back into the portable cleaning device 10 through the suction nozzle 22.
[0044] The first contact surface 21 of the accessory brush 20 has a first edge 211 and a second edge 212 that are disposed opposite to each other, with the first edge 211 being farther away from the nozzle opening 22 relative to the second edge 212. Figures 4a-4b As shown. When the accessory brush 20 is stored in the storage cavity 31, the first edge 211 and the second edge 212 are arranged sequentially from the opening 32 toward the bottom 311 of the storage cavity 31, that is, at this time, the first edge 211 is closer to the opening 32 of the storage box 30 relative to the second edge 212. The first support surface 331 has a third edge 3311 and a fourth edge 3312 arranged opposite to each other, the third edge 3311 and the fourth edge 3312 are arranged sequentially from the opening 32 toward the bottom 311 of the storage cavity 31, that is, the third edge 3311 is closer to the opening 32 of the storage box 30 relative to the fourth edge 3312, as shown. Figure 2 and Figure 3 As shown.
[0045] When the accessory brush 20 is stored in the storage cavity 31, the first abutting surface 21 contacts the first supporting surface 331, and the first edge 211 abuts the third edge 3311, and the second edge 212 abuts the fourth edge 3312. At this time, the first abutting surface 21 and the first supporting surface 331 can be completely fitted together, or the first abutting surface 21 and part of the surface of the first supporting surface 331 can be fitted together. Since the cleaning fluid flowing out of the accessory brush 20 gathers at the bottom 311 of the storage cavity 31, the suction port 22 of the accessory brush 20 in this embodiment is set close to the bottom 311 of the storage cavity 31, which is beneficial for the accessory brush 20 to fully recover the cleaning fluid at the bottom 311 of the storage cavity 31 through the suction port 22.
[0046] Furthermore, the fourth edge 3312 of the first support surface 331 is located further away from the opening 32 than other positions in the storage cavity 31. In other words, the fourth edge 3312 of the first support surface 331 is located at the lowest position in the storage cavity 31. When the accessory brush 20 is stored in the storage cavity 31, the second edge 212 at the front end of the accessory brush 20 is at the lowest position in the storage cavity 31. At this time, the suction nozzle 22 of the accessory brush 20 is as close as possible to this lowest position in the storage cavity 31, which further facilitates the accessory brush 20 to fully recover the cleaning fluid at the bottom 311 of the storage cavity 31 through the suction nozzle 22.
[0047] Please refer to the following: Figure 6 , Figure 6 This is a schematic diagram of an embodiment of the relative positional relationship between the roller brush and the first support surface of this application.
[0048] In one embodiment, the accessory brush 20 has a roller brush 23. The roller brush 23 is rotatable about a predetermined rotation axis O. When the user operates the accessory brush 20 to perform cleaning work, the roller brush 23 rotates about the predetermined rotation axis O to clean the surface to be cleaned.
[0049] A first perpendicular segment L1 exists between the third edge 3311 of the first support surface 331 and the set rotation axis O, and a second perpendicular segment L2 exists between the third edge 3311 and the fourth edge 3312. The first perpendicular segment L1 is perpendicular to the second perpendicular segment L2, and the distance between the third edge 3311 and the set rotation axis O is less than the distance between other positions on the first support surface 331 and the set rotation axis O. When the first abutting surface 21 is fully in contact with the first support surface 331, the perpendicular segment between the first edge 211 of the first abutting surface 21 and the set rotation axis O is also perpendicular to the perpendicular segment between the first edge 211 and the second edge 212, and the distance between the first edge 211 and the set rotation axis O is less than the distance between other positions on the first abutting surface 21 and the set rotation axis O.
[0050] In this embodiment, the surface morphology of the first support surface 331 is similar to the surface morphology of the first contact surface 21 at the front end of the accessory brush 20, so that the first contact surface 21 and the first support surface 331 can fit well together, thereby making the accessory brush 20 reliably and stably stored in the storage box 30, and preventing the accessory brush 20 from shaking in the storage box 30.
[0051] In one embodiment, the accessory brush 20 includes a main body 24, a handle 25, and a connecting portion 26. The main body 24 is connected to the handle 25 via the connecting portion 26. A cleaning component (e.g., a roller brush 23) for cleaning the surface to be cleaned is located on the main body 24, and the handle 25 is for the user to hold. During cleaning using the accessory brush 20, the user holds the handle 25, causing the main body 24 to move across the surface to be cleaned. When the accessory brush 20 is stored in the storage cavity 31, at least a portion of the main body 24 is embedded in the storage cavity 31.
[0052] The support surface 33 also includes a second support surface 332, which is located at the opening 32 of the storage box 30. Specifically, the second support surface 332 is located on the outer periphery of the opening 32 and extends circumferentially along the opening 32. When the accessory brush 20 is stored in the storage cavity 31, the connecting part 26 is supported by the second support surface 332, so that the accessory brush 20 is reliably and stably stored in the storage box 30, minimizing the possibility of the accessory brush 20 shaking in the storage box 30.
[0053] Furthermore, the surface of the connecting portion 26 that contacts the second support surface 332 is the second abutment surface 261, and the shape of the second abutment surface 261 matches the shape of the second support surface 332. In other words, in this embodiment, the surface morphology of the second support surface 332 imitates the surface morphology of the second abutment surface 261, so that the second abutment surface 261 and the second support surface 332 can fit well together, thereby allowing the accessory brush 20 to be reliably and stably stored in the storage box 30, and preventing the accessory brush 20 from shaking in the storage box 30. Figure 4a and Figure 5 The example demonstrates a case where the second abutment surface 261 is an arc surface and the second support surface 332 is an arc surface that is adapted to it, and the second abutment surface 261 and the second support surface 332 can fit well together.
[0054] It should be noted that the storage box 30 in this embodiment of the application has a first support surface 331 and a second support surface 332. The first support surface 331 and the second support surface 332 cooperate to support the accessory brush 20, so that the accessory brush 20 is reliably and stably stored in the storage box 30, and the accessory brush 20 is prevented from shaking in the storage box 30 as much as possible.
[0055] Please see Figure 2 , Figure 3 and Figure 7 , Figure 7 This is a structural diagram of another embodiment of the brush being stored in a storage box, as shown in the appendix to this application.
[0056] In one embodiment, the receiving cavity 31 includes a first sub-cavity 312 and a second sub-cavity 313 that are interconnected. The first sub-cavity 312 is used to receive the accessory brush 20, specifically, the portion of the accessory brush 20 embedded in the receiving cavity 31 is located in the first sub-cavity 312. When the accessory brush 20 is received in the receiving cavity 31, the inner wall surface of the second sub-cavity 313 is away from the accessory brush 20, meaning that at least a portion of the second sub-cavity 313 is an empty cavity. This embodiment increases the volume of the receiving cavity 31 by providing the second sub-cavity 313, which helps to lower the liquid level in the receiving cavity 31 and avoids the problem of excessive areas of the accessory brush 20 being submerged in the cleaning fluid due to an excessively high liquid level during the self-cleaning process, thereby minimizing the contamination of the accessory brush 20 by dirty cleaning fluid.
[0057] It should be noted that, in this embodiment, the inner wall surfaces of the storage cavity 31, except for the first support surface 331, are not completely fitted with the accessory brush 20. That is, there are more or less cavities between the inner wall surfaces of the storage cavity 31, except for the first support surface 331, and the accessory brush 20. For example, the inner wall surface of the second sub-cavity 313 is far from the accessory brush 20, making at least a portion of the second sub-cavity 313 a cavity. This embodiment rationally sets the inner wall structure of the storage cavity 31 according to the amount of cleaning fluid output by the accessory brush 20 during the self-cleaning process, so as to reasonably control the maximum liquid level in the storage cavity 31 and avoid the problem of excessive areas of the accessory brush 20 being immersed in the cleaning fluid due to excessively high liquid levels during the self-cleaning process, thereby minimizing the contamination of the accessory brush 20 by dirty cleaning fluid.
[0058] In one embodiment, the bottom 311 and opening 32 of the receiving cavity 31 are along a first direction (e.g., Figure 2 (As indicated by the middle arrow X, the same applies below) relative setting. Storage box 30 also defines a second direction (such as...). Figure 3 As indicated by the middle arrow Y (the same applies below), the second direction is perpendicular to the first direction. When the storage box 30 is assembled with the portable cleaning device 10, the second direction can be perpendicular to the relative direction between the storage box 30 and the portable cleaning device 10, or the second direction can be parallel to the relative direction between the storage box 30 and the portable cleaning device 10. Figures 1 to 3 An example is shown where the second direction is perpendicular to the relative direction of the storage box 30 and the portable cleaning device 10.
[0059] The storage box 30 is also provided with a limiting block 34 located in the storage cavity 31, such as Figure 2As shown. When the accessory brush 20 is stored in the storage cavity 31, the limiting block 34 abuts against the accessory brush 20 to restrict the position of the accessory brush 20 in the second direction. In this embodiment, based on the support of the accessory brush 20 by the first support surface 331 and the second support surface 332, the limiting block 34 restricts the position of the accessory brush 20 in the storage cavity 31, which further facilitates the reliable and stable storage of the accessory brush 20 in the storage box 30, thereby minimizing the movement of the accessory brush 20 in the storage box 30. For example, the storage cavity 31 is provided with limiting blocks 34 on both sides in the second direction, so as to restrict the position of the accessory brush 20 in the second direction by the cooperation of the limiting blocks 34 on both sides.
[0060] Please refer to the following: Figure 8 , Figure 8 This is a schematic diagram of the structure of an embodiment of the cleaning system of this application.
[0061] In one embodiment, the storage box 30 is detachably disposed on the portable cleaning device 10. Further, when the storage box 30 is assembled on the portable cleaning device 10, in a first direction, the bottom of the storage box 30 is higher than the bottom of the portable cleaning device 10, specifically, the bottom of the storage box 30 and the bottom of the portable cleaning device 10 have a height difference H.
[0062] In this embodiment, by setting the bottom of the storage box 30 higher than the bottom of the portable cleaning device 10, the bottom of the storage box 30 is prevented from touching the ground before the portable cleaning device 10 when the user places it on the ground, thus preventing the storage box 30 from detaching from the portable cleaning device 10. This is especially important in cases where the storage box 30 and the portable cleaning device 10 are connected via a slot, with the storage box 30 inserted into the portable cleaning device 10 from top to bottom (specifically, into the connecting structure 16). If the bottom of the storage box 30 touches the ground before the portable cleaning device 10, the storage box 30 is likely to detach from the portable cleaning device 10.
[0063] Please see Figure 4a and Figure 9 , Figure 9 This is a schematic diagram of another embodiment of the cleaning system of this application. The attachment brush 20 of this application will be described below.
[0064] In one embodiment, the portable cleaning device 10 also includes a self-cleaning button 11. The self-cleaning button 11 is operated by the user to trigger the self-cleaning function of the portable device. The self-cleaning button 11 is located at the end of the handle portion 25 of the accessory brush 20 away from the connecting portion 26. In this way, when the user uses the accessory brush 20, they hold the handle portion 25, and the self-cleaning button 11 is away from the user's hand, reducing the risk of accidentally pressing the self-cleaning button 11 during cleaning. Furthermore, since the end of the handle portion 25 away from the connecting portion 26 is positioned upwards when the accessory brush 20 is stored in the storage box 30, the self-cleaning button 11 is also positioned upwards, making it easy for the user to observe and operate the self-cleaning button 11.
[0065] Specifically, the self-cleaning button 11 has an operating surface 111 for user operation. That is, the user operates the self-cleaning button 11 through the operating surface 111 to trigger the self-cleaning function of the portable device. For example, in the case where the user operates the self-cleaning button 11 by pressing, the user presses the self-cleaning button 11 by contacting the operating surface 111, thereby triggering the self-cleaning function of the portable device.
[0066] In one embodiment, the portable cleaning device 10 further includes a display screen 12 with a display surface 121. The display screen 12 displays relevant information about the portable cleaning device 10 through the display surface 121, allowing the user to intuitively understand the relevant information of the portable cleaning device 10. The display screen 12 is located at the connecting portion 26, and the display surface 121 of the display screen 12 faces away from the main body portion 24. When the accessory brush 20 is stored in the storage box 30, the display surface 121 of the display screen 12 faces away from the main body portion 24, making it convenient for the user to observe the display surface 121 of the display screen 12.
[0067] It should be noted that the plane where the operating surface 111 is located and the plane where the display surface 121 is located form an angle α, which is between 45° and 135°, such as 45°, 90°, 135°, etc. Figure 4a As shown. Further, the angle α formed by the plane where the operation surface 111 is located and the plane where the display surface 121 is located is preferably 90°. In this way, when the accessory brush 20 is stored in the storage box 30, the display surface 121 of the display screen 12 faces the front of the portable cleaning device 10, making it convenient for the user to observe the display screen 12 from the front of the portable cleaning device 10, and the self-cleaning button 11 is also positioned upwards, making it convenient for the user to observe and operate the self-cleaning button 11.
[0068] In one embodiment, the portable cleaning device 10 further includes a sensor. The sensor is located on the accessory brush 20 and is used to detect whether the accessory brush 20 has reached a set position in the storage box 30. When the accessory brush 20 reaches the set position, the user is allowed to trigger the self-cleaning function of the portable cleaning device 10 via the self-cleaning button 11. When the accessory brush 20 has not reached the set position, the user is not allowed to trigger the self-cleaning function of the portable cleaning device 10 via the self-cleaning button 11. In this case, even if the user operates the self-cleaning button 11, the self-cleaning button 11 cannot trigger the self-cleaning function of the portable cleaning device 10, thus preventing the user from accidentally touching the self-cleaning button 11 and accidentally triggering the self-cleaning function of the portable cleaning device 10.
[0069] It should be noted that the set position of the accessory brush 20 in the storage box 30 can be the position of the accessory brush 20 when it is supported on the first support surface 331 and the second support surface 332 described in the above embodiment. The sensor can be a Hall sensor or the like, which can determine whether the accessory brush 20 has reached the set position in the storage box 30 through distance detection, and is not limited here.
[0070] In one embodiment, the portable cleaning device 10 further includes a main mode button 13 and a sub-mode button 14. The main mode button 13 is located on the side of the handle portion 25 away from the main body portion 24, and the sub-mode button 14 is located on the side of the handle portion 25 facing the main body portion 24. The center of the main mode button 13 and the center of the sub-mode button 14 are on the same plane (e.g., ...). Figure 4a As shown in the mid-plane M (hereinafter the same), and this plane is parallel to the first direction and the relative direction of the main body 24 and the handle 25. When the user holds the handle 25, the main mode button 13 is located near the user's thumb, and the sub-mode button 14 is located near the user's index finger, making it convenient for the user to operate the main mode button 13 and the sub-mode button 14 with one hand.
[0071] Furthermore, since the user does not need to hold the sub-mode button 14 pressed for an extended period, the center of the main mode button 13 is positioned further away from the center of the sub-mode button 14 from the connecting portion 26. In other words, when the user holds the handle portion 25, the sub-mode button 14 is located in front of the user's hand, allowing the user to easily touch and press the sub-mode button 14 by extending their index finger forward. This avoids accidental touches of the sub-mode button 14 by the user's index finger and improves the comfort of the user's grip.
[0072] For example, in one exemplary embodiment, the main mode key 13 can be designed as a toggle switch, corresponding to three main modes: standby mode, carpet mode, and fabric mode. The user switches between these three main modes by toggling the main mode key 13. The sub-mode key 14 also corresponds to three sub-modes: spot mode, smart mode, and water absorption mode. The user switches between these three sub-modes by pressing the sub-mode key 14. In another exemplary embodiment, the main mode key 13 corresponds to three main modes: standby mode, smart mode, and spot mode. The user switches between these three main modes by toggling the main mode key 13. The sub-mode key 14 corresponds to the water absorption mode. The user switches the portable device to the water absorption mode by pressing the sub-mode key 14.
[0073] Please refer to the following: Figure 10 , Figure 10 This is a structural schematic diagram of another embodiment of the brush in the appendix to this application.
[0074] In one embodiment, the main body 24 of the accessory brush 20 also has a detachable brush head 241, through which the accessory brush 20 performs cleaning work. The portable cleaning device 10 also includes a brush head release button 15. The brush head release button 15 is located on the side of the main body 24 facing the handle 25, and is used to selectively release the brush head 241 on the main body 24 so that the user can replace and maintain the brush head 241.
[0075] When the accessory brush 20 is stored in the storage box 30, the brush head 241 of the accessory brush 20 is primarily stored in the storage box 30, with the first contact surface 21 of the brush head 241 supported within the storage box 30. Cleaning fluid flows out through the brush head 241, and the self-cleaning process of the accessory brush 20 mainly cleans the brush head 241. Specifically, the accessory brush 20 outputs cleaning fluid through the brush head 241, immersing the brush head 241 in the cleaning fluid for cleaning. Furthermore, the suction nozzle 22 of the accessory brush 20 is located on the brush head 241, and the accessory brush 20 collects the cleaning fluid from the storage cavity 31 through the suction nozzle 22 on the brush head 241.
[0076] Please see Figure 11 , Figure 11 This is a flowchart illustrating an embodiment of the control method for the cleaning system of this application.
[0077] S101: Determine whether a setting command has been received.
[0078] In this embodiment, if a setting instruction is received, step S102 is executed; if no setting instruction is received, step S101 is executed.
[0079] When the portable cleaning device 10 has a self-cleaning function, the accessory brush 20 outputs cleaning fluid into the storage cavity 31, allowing the accessory brush 20 to immerse itself in the cleaning fluid within the storage cavity 31 for cleaning. Afterwards, a setting command is generated to recycle the cleaning fluid in the storage cavity 31. If cleaning fluid remains after the portable cleaning device 10 completes its cleaning work, the residual cleaning fluid will flow out of the accessory brush 20 under gravity. Afterwards, a setting command is generated to recycle the cleaning fluid in the storage cavity 31.
[0080] S102: In response to a set command, control the accessory brush to recycle the cleaning fluid in the storage chamber.
[0081] In this embodiment, if a setting command is received, the accessory brush 20 is controlled to collect the cleaning fluid in the storage cavity 31 in response to the setting command. If the portable cleaning device 10 has a self-cleaning function, the accessory brush 20 is immersed in the cleaning fluid in the storage cavity 31 for cleaning. After cleaning is completed, the setting command is generated, and the accessory brush 20 is controlled to collect the cleaning fluid in the storage cavity 31 in response to the setting command. Alternatively, the accessory brush 20 outputs cleaning fluid for self-cleaning, and simultaneously collects the cleaning fluid in the storage cavity 31 in response to the setting command.
[0082] If residual cleaning fluid remains after the portable cleaning device 10 has completed the cleaning work, the residual cleaning fluid will flow out of the accessory brush 20 under the action of gravity. Then, the setting command is generated, and in response to the setting command, the accessory brush 20 is controlled to collect the cleaning fluid in the storage cavity 31.
[0083] In one embodiment, the portable cleaning device 10 has an accessory brush 20 and a connecting structure 16. The connecting structure 16 is used to connect to a storage box 30 to store the accessory brush 20. The storage box 30 has a storage cavity 31 and an opening 32 communicating with the storage cavity 31. The bottom 311 of the storage cavity 31 and the opening 32 are arranged opposite to each other. The accessory brush 20 can be inserted into the storage cavity 31 through the opening 32 and facing the bottom 311 of the storage cavity 31. When the accessory brush 20 is stored in the storage cavity 31, the cleaning fluid flows out from the accessory brush 20 under the action of gravity and collects at the bottom 311 of the storage cavity 31.
[0084] In the above manner, when the portable cleaning device 10 has a self-cleaning function, the storage cavity 31, as a container, can hold the accessory brush 20 and the cleaning fluid output by the accessory brush 20, so that the accessory brush 20 is immersed in the cleaning fluid in the storage cavity 31, which is conducive to a comprehensive and thorough cleaning of the inside and outside of the accessory brush 20; and when the portable cleaning device 10 has residual cleaning fluid after completing the cleaning work, the residual cleaning fluid flows out from the accessory brush 20 and collects at the bottom 311 of the storage cavity 31, without leaking to the outside, which can effectively reduce the risk of residual cleaning fluid leakage.
