DETAILED DESCRIPTION

[0141] In order to better understand the above technical solution, the technical solution of the embodiment of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiment of the present application and the specific features in the embodiment are detailed descriptions of the technical solution of the embodiment of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiment of the present application and the technical features in the embodiment can be combined with each other.

[0142] Example 1

[0143] As shown in Figure 1, according to the first aspect of an embodiment of the present application, a box body 100 is proposed, and a accommodating space is formed inside the box body 100, and the accommodating space is used to accommodate cleaning liquid. The box body 100 is provided with a liquid outlet 131 for the cleaning liquid to flow out; the box body 100 includes: a delivery pipe 110, which is arranged in the accommodating space, one end of which is connected to the liquid outlet 131, and the other end is adjacent to the bottom wall of the box body 100, and the cleaning liquid is delivered to the liquid outlet 131 through the delivery pipe 110 under the drive of an external driving member; an adapter bracket 120, which is used to connect the delivery pipe 110 and the liquid outlet 131.

[0144] It can be understood that the box body 100 provided in the embodiment of the present application is provided with a delivery pipe 110 and a fixing member 180. Among them, a holding space is formed inside the box body 100, and the cleaning liquid can be stored through the holding space. And the box body 100 is provided with a liquid outlet 131 for the cleaning liquid in the holding space to flow out. The delivery pipe 110 is arranged in the holding space, and one end of the delivery pipe 110 is connected to the liquid outlet 131, and the other end is arranged at the inner bottom wall of the box body 100. Outside the box body 100, a driving member can be provided to act on the delivery pipe 110. Under the drive of the external driving member, the cleaning liquid in the holding space can be discharged to the outside of the box body 100 along the delivery pipe 110 through the liquid outlet 131. And the delivery pipe 110 is arranged so as to facilitate the delivery of all the cleaning liquid in the holding space to the outside of the box body 100. The adapter bracket 120 is arranged in the accommodating space, and the adapter bracket 120 is connected to the delivery pipe 110 and the liquid outlet 131. On the one hand, the adapter bracket 120 can transfer the cleaning liquid in the delivery pipe 110 to the liquid outlet 131, which is convenient for the spatial layout in the accommodating space; on the other hand, it can support and fix the delivery pipe 110. When the cleaning liquid in the delivery pipe 110 swells and causes the volume to increase, the fixing force applied by the adapter bracket 120 to the delivery pipe 110 can offset the expansion force applied by the cleaning liquid with increased volume on the delivery pipe 110, thereby ensuring that the delivery pipe 110 is firmly connected, avoiding falling off, and ensuring that the cleaning liquid in the accommodating space is continuously and stably delivered to the outside of the box body 100.

[0145] It should be noted that the box body 100 is placed vertically, the liquid outlet 131 is located at the upper end of the box body 100, and the liquid inlet end of the delivery pipe 110 is arranged near the bottom wall inside the box body 100, and the other end is connected to the liquid outlet 131. When there is no need to deliver the cleaning liquid to the outside of the box body 100, the cleaning liquid will not flow out of the liquid outlet 131. When it is necessary to deliver the cleaning liquid to the outside of the box body 100, a negative pressure environment can be created in the delivery pipe 110 by the driving member to pump the cleaning liquid in the storage space near the bottom wall of the box body 100 to the outside of the box body 100.

[0146] Exemplarily, the external driving member can be a pump body, which can be connected to the liquid outlet 131 through a pipeline. The cleaning liquid in the accommodating space is pumped along the delivery pipe 110 to the liquid outlet 131 through the pump body, and flows out from the liquid outlet 131 along the pipeline to the outside of the box body 100, so that the cleaning liquid can be used.

[0147] In some examples, as shown in Figure 1, the above-mentioned box body 100 also includes: a box body 130, the interior of the above-mentioned box body 130 is formed with the above-mentioned accommodating space, and the top of the above-mentioned box body 130 is formed with an opening; a cover body 140, which is arranged to cover the above-mentioned opening; wherein, a placement groove 133 is formed at one end of the inside of the above-mentioned box body 130 away from the above-mentioned opening; the liquid inlet end of the above-mentioned delivery pipe 110 is inserted into the above-mentioned placement groove 133.

[0148] As will be appreciated, the box body 100 is further provided with a main body 130 and a cover 140. The top of the main body 130 may be opened, and a storage space may be formed inside the main body 130. Cleaning liquid can be poured into the storage space through the opening to store the cleaning liquid. The cover 140 can be placed over the opening to seal the storage space, preventing foreign matter from entering the storage space and contaminating the cleaning liquid, thereby ensuring the cleanliness of the cleaning liquid. Furthermore, the installation of the cover 140 prevents the cleaning liquid in the box body 100 from spilling out of the opening when the box body 100 is moved, thereby improving stability. The liquid outlet 131 may be located on the side of the main body 130 closest to the opening, and a placement groove 133 may be formed on the end of the main body 130 away from the opening. The liquid inlet end of the delivery pipe 110 can be inserted into the placement groove 133, with sufficient space between the bottom wall of the placement groove 133 and the bottom wall of the placement groove 133 to facilitate the suction of cleaning liquid from the storage space into the delivery pipe 110.

[0149] It is understandable that by providing the placement groove 133, the side of the delivery pipe 110 close to the bottom end of the box body 100 can be fixed, and the side of the delivery pipe 110 close to the liquid outlet 131 can be fixed by the adapter bracket 120. When the cleaning liquid in the delivery pipe 110 swells and causes the volume to increase, the fixing force applied to the delivery pipe 110 by the adapter bracket 120 and the placement groove 133 at the same time can offset the expansion force applied to the delivery pipe 110 by the cleaning liquid with increased volume, thereby ensuring that the delivery pipe 110 is firmly connected and prevented from falling off, and ensuring that the cleaning liquid in the accommodating space is continuously and stably delivered to the outside of the box body 100. Furthermore, the box body 100 can also be provided with a fixing member 180, which is sleeved on the delivery pipe 110, and the bottom of the fixing member 180 is connected to the notch of the placement groove 133 to increase the fixing area of ​​the delivery pipe 110 and improve the fixing effect of the delivery pipe 110.

[0150] For example, the box body 130 may be provided with a buckle position, and the side of the cover 140 facing the opening of the box body 130 may be provided with a buckle plate, and the cover 140 is connected to the box body 130 by buckling the buckle plate in the buckle position.

[0151] In some examples, as shown in FIG. 1 , the adapter bracket 120 includes a connecting portion 121 connected to the end of the cover 140 facing the opening; and a fixing portion 122 for connecting the liquid outlet 131 and the delivery pipe 110 .

[0152] It can be understood that the adapter bracket 120 is provided with a connecting portion 121 and a fixing portion 122. Among them, the connecting portion 121 is connected to the end of the cover body 140 facing the opening, and the fixing portion 122 is connected to the connecting portion 121, and the adapter bracket 120 is fixed to the cover body 140 as a whole through the connecting portion 121. And the fixing portion 122 can be connected to the liquid outlet 131 and the delivery pipe 110 respectively, so that the cleaning liquid in the delivery pipe 110 can be delivered from the fixing portion 122 to the liquid outlet 131. The delivery direction of the cleaning liquid can be adjusted by the fixing portion 122, which is beneficial to the spatial planning of the accommodation space. The fixing portion 122 is connected to the connecting portion 121. Since the connecting portion 121 is fixed to the cover body 140, the position of the fixing portion 122 relative to the cover body 140 can be fixed, thereby providing a fixing force to the delivery pipe 110 connected to the fixing portion 122 to offset the expansion force exerted on the delivery pipe 110 by the cleaning liquid whose volume increases due to swelling.

[0153] For example, the connecting portion 121 and the fixing portion 122 can be made by an integral molding process to ensure

[0154] In some examples, as shown in FIG. 1 , the connection portion 121 is provided with a groove 1211 , and a protrusion 141 is formed on one end of the cover 140 facing the opening, and the protrusion 141 is inserted into the groove 1211 .

[0155] It is understood that a groove 1211 may be provided at the end of the connection portion 121 facing the open portion, and a protrusion 141 may be formed at a corresponding position on the end of the cover 140 facing the open portion. The protrusion 141 is inserted into the groove 1211 to secure the connection portion 121 to the cover 140. Furthermore, the protrusion 141 and the groove 1211 may form an interference fit to ensure a secure connection between the connection portion 121 and the cover 140, thereby ensuring that the fixing portion 122 provides sufficient fixing force on the delivery pipe 110 to offset the expansion force exerted on the delivery pipe 110 by the cleaning liquid due to swelling.

[0156] In some examples, as shown in Figure 1, the above-mentioned fixed portion 122 includes: a first tube body 1221, connected to the liquid outlet end of the above-mentioned delivery pipe 110; a second tube body 1222, one end of the above-mentioned second tube body 1222 is connected to the above-mentioned first tube body 1221, and the other end is connected to the above-mentioned liquid outlet 131; wherein, the axis of the above-mentioned first tube body 1221 and the axis of the above-mentioned second tube body 1222 intersect.

[0157] It is understood that the adapter bracket 120 is provided with a first tube body 1221 and a second tube body 1222. The first tube body 1221 is connected to the liquid outlet end of the delivery pipe 110, one end of the second tube body 1222 is connected to the first tube body 1221, and the other end of the second tube body 1222 is connected to the liquid outlet 131. Both the first tube body 1221 and the second tube body 1222 are hollow tubes, with a first cavity formed inside the first tube body 1221 and a second cavity formed inside the second tube body 1222. The first and second cavities are interconnected, and the liquid outlet end of the delivery pipe 110 can be inserted into the first cavity, while the second cavity is connected to the liquid outlet 131. Moreover, the central axis of the first tube body 1221 and the central axis of the second tube body 1222 intersect, that is, the first tube body 1221 and the second tube body 1222 are set in different directions, so that the cleaning liquid is transported to the adapter bracket 120 through the delivery pipe 110, and then transported to the liquid outlet 131 after changing the delivery direction, which is beneficial to the spatial layout inside the box body 100.

[0158] Exemplarily, the first tube body 1221 and the second tube body 1222 can be manufactured by an integrated molding process to improve the overall structural strength of the adapter bracket 120, prevent the cleaning liquid from leaking from the connection between the first tube body 1221 and the second tube body 1222, and improve the fixing force of the adapter bracket 120 on the conveying pipe 110.

[0159] In some examples, the axis of the first tube 1221 and the axis of the second tube 1222 are perpendicular to each other.

[0160] It can be understood that the delivery pipe 110 can be vertically arranged in the accommodation space to ensure that the area of ​​the accommodation space occupied by the delivery pipe 110 is minimized, and it is convenient to place the groove 133 to fix the delivery pipe 110. And the liquid outlet 131 can be opened on the side of the side wall of the box body 100 close to the opening. The axis of the first tube body 1221 and the axis of the second tube body 1222 can be perpendicular to each other, that is, the central axis of the delivery pipe 110 and the central axis of the liquid outlet 131 are perpendicular to each other. Such an arrangement allows, under the action of an external driving member, the cleaning liquid in the accommodation space to be vertically transported upward along the delivery pipe 110 to the adapter bracket 120, and after being turned by the adapter bracket 120, it is horizontally transported along the second tube body 1222 to the liquid outlet 131, and then flows out from the liquid outlet 131 to the outside of the box body 100. This ensures that the cleaning liquid is transported smoothly and will not be affected by the tilt angle.

[0161] In some examples, as shown in FIG. 1 , the liquid outlet 131 is formed on a side of the inner wall of the box body 130 close to the cover 140 , and a valve body 132 is provided inside the liquid outlet 131 .

[0162] It is understandable that the liquid outlet 131 can be formed on the inner wall of the box body 130 near the side of the cover body 140. Since the liquid inlet end of the delivery pipe 110 is located at the bottom wall of the box body 130, with this arrangement, when there is no need to transport the cleaning liquid to the outside of the box body 100, the cleaning liquid will not flow out from the liquid outlet 131. When it is necessary to transport the cleaning liquid to the outside of the box body 100, a negative pressure environment can be formed in the delivery pipe 110 by the driving member to pump the cleaning liquid in the storage space adjacent to the bottom wall of the box body 100 to the outside of the box body 100. Furthermore, a valve body 132 can be provided inside the liquid outlet 131. When there is no need to transport the cleaning liquid to the outside of the box body 100, the valve body 132 is in a closed state, and the liquid outlet 131 ends at the valve body 132, thereby preventing the liquid in the storage space from flowing out from the liquid outlet 131. When it is necessary to transport the cleaning liquid outside the box body 100, the valve body 132 can be opened to connect the liquid outlet 131 to the outside of the box body 100 to ensure smooth outflow of the cleaning liquid.

[0163] In some examples, as shown in FIG. 1 , the box body 100 further includes a sealing ring 150 , which is clamped at the connection between the adapter bracket 120 and the delivery pipe 110 and / or the connection between the adapter bracket 120 and the liquid outlet 131 .

[0164] It is understandable that the box body 100 is also provided with a sealing ring 150. Specifically, the sealing ring 150 can be clamped at the connection between the adapter bracket 120 and the delivery pipe 110 to seal the connection between the adapter bracket 120 and the delivery pipe 110, ensuring that the cleaning liquid in the storage space will not leak during the process of being transported to the adapter bracket 120 along the delivery pipe 110. At the same time, the sealing ring 150 can also be clamped at the connection between the adapter bracket 120 and the liquid outlet 131 to seal the connection between the adapter bracket 120 and the liquid outlet 131, ensuring that the cleaning liquid in the storage space will not leak during the process of being transported to the liquid outlet 131 along the adapter bracket 120. In addition, when the external driving member forms a negative pressure environment in the cavity between the liquid outlet 131 and the liquid inlet end of the delivery pipe 110 to pump the cleaning liquid, it is ensured that the negative pressure environment will not be destroyed, thereby improving the stability of the cleaning liquid delivery.

[0165] In some examples, as shown in FIG1 , the sealing ring 150 is clamped at the connection between the first tube 1221 and the liquid outlet end of the delivery pipe 110 ; and / or is clamped at the connection between the second tube 1222 and the valve body 132 .

[0166] It is understood that the sealing ring 150 can be sandwiched between the first tube 1221 and the liquid outlet end of the delivery pipe 110. Specifically, the inner wall of the first tube 1221 can be provided with a groove, and the sealing ring 150 can be disposed within the groove. When the liquid outlet end of the delivery pipe 110 is inserted into the first cavity, the sealing ring 150 can be sleeved onto the outer wall of the delivery pipe 110 to seal the gap between the delivery pipe 110 and the inner wall of the first tube 1221. Simultaneously, the sealing ring 150 can also be sandwiched between the connection between the second tube 1222 and the valve body 132. Specifically, the inner wall of the second tube body 1222 may be provided with a ring groove, and the sealing ring 150 may be arranged in the ring groove, and when the valve body 132 is inserted into the second cavity, the sealing ring 150 may be sleeved on the outer wall of the valve body 132 to seal the gap between the valve body 132 and the inner wall of the second tube body 1222. Through the provision of the sealing ring 150, it can be ensured that the cleaning liquid in the accommodating space will not leak during the process of being transported to the liquid outlet 131 along the adapter bracket 120. At the same time, when the external driving component forms a negative pressure environment in the cavity between the liquid outlet 131 and the liquid inlet end of the delivery pipe 110 to pump the cleaning liquid, it is ensured that the negative pressure environment will not be destroyed, thereby improving the stability of the cleaning liquid delivery.

[0167] In some examples, as shown in FIG. 1 , the box body 100 further includes a filter 160 disposed in the placement groove 133 and covering the liquid inlet end of the delivery pipe 110 .

[0168] It is understood that the box body 100 may also be provided with a filter 160. Specifically, the filter 160 may be placed in the placement groove 133 and covered at the liquid inlet end of the delivery pipe 110. This filter 160 can filter out impurities such as particulate matter from the cleaning liquid entering the delivery pipe 110, ensuring the cleanliness of the cleaning liquid flowing out of the liquid outlet 131 of the box body 100 and improving reliability.

[0169] In some examples, as shown in FIG. 1 , the box body 100 further includes: a liquid level sensor 170 , which is disposed at an end of the box body 130 away from the opening, and is used to sense liquid level information in the accommodating space.

[0170] It is understandable that the box body 100 is also provided with a liquid level sensor 170. Specifically, the liquid level sensor 170 can be provided at the end of the interior of the box body 130 away from the opening. The liquid level sensor 170 can sense the liquid level information in the storage space to determine the current storage amount of the cleaning liquid in the storage space. And a prompter can be provided, which is connected to the liquid level sensor 170. When the liquid level sensor 170 senses that the storage amount of the cleaning liquid in the storage space is lower than the preset minimum storage amount, the prompter can issue a prompt to the user that the cleaning liquid is too low, so as to remind the user to add cleaning liquid as soon as possible. The prompter can emit an audible and visual alarm, or can send a reminder message to add cleaning liquid to the user's mobile terminal.

[0171] For example, the liquid level sensor 170 may be provided with a float that can float on the surface of the cleaning liquid. Changes in the liquid level of the cleaning liquid will cause changes in the height position of the float. When the height of the float is lower than the minimum preset height, it can be said that the level of the cleaning liquid in the storage space is too low and cleaning liquid needs to be added as soon as possible. Alternatively, the liquid level sensor 170 can emit a laser into the cleaning liquid and observe the liquid level of the cleaning liquid by receiving the reflected laser. When the liquid level of the cleaning liquid changes, the angle of the reflected laser changes. When the angle of the reflected laser changes to the reflection angle when the liquid level of the cleaning liquid reaches the minimum level, a signal prompting the addition of cleaning liquid can be issued.

[0172] In some examples, the delivery pipe 110 is a polypropylene pipe.

[0173] It is understandable that the conveying pipe 110 can be made of polypropylene. Polypropylene has a wide operating temperature range and can resist corrosion from acids, alkalis, saline solutions and various organic solvents when the operating environment temperature is below 80 degrees Celsius. Since the cleaning liquid is an organic solvent, the use of a polypropylene pipe can prevent the conveying pipe 110 from being corroded, improve reliability, and extend the service life of the conveying pipe 110. In addition, the polypropylene material has high-strength mechanical properties. The conveying pipe 110 made of polypropylene has good structural strength, which prevents the conveying pipe 110 from being deformed when the organic solvent swells and the volume increases, exerting an expansion force on the inner wall of the conveying pipe 110. The fact that the conveying pipe 110 is not easily deformed ensures the connection stability between the conveying pipe 110 and the placement groove 133, as well as the connection stability between the conveying pipe 110 and the adapter bracket 120.

[0174] According to the second aspect of an embodiment of the present application, a cleaning device is proposed, comprising: a box body 100 as described in any one of the above technical solutions; a driving member, connected to the above liquid outlet 131, for transporting the cleaning liquid in the above box body 100 along the above delivery pipe 110 through the above liquid outlet 131 to the outside of the above box body 100.

[0175] It is understood that the cleaning device is provided with a box body 100 according to any of the above technical solutions, and therefore has all the beneficial effects of the box body 100, which will not be described in detail here. The cleaning device is also provided with a driving member, which can be connected to the liquid outlet 131 via a pipeline. The driving member can transport the cleaning liquid in the storage space along the delivery pipe 110 to the liquid outlet 131, and then flow out of the box body 100 through the pipeline.

[0176] For example, the driving member can use a first pump body. The cleaning device can also be provided with a clean water tank, a junction pipe and a second pump body. When using cleaning liquid, the cleaning liquid in the box body 100 can be pumped to the junction pipe by the first pump body, and at the same time, the clean water in the clean water tank can be pumped to the junction pipe by the second pump body. The cleaning liquid and clean water are mixed at the junction pipe, and the cleaning liquid is diluted with clean water to reach the use concentration. The clean water and the cleaning liquid are stored separately. When only clean water is needed, the second pump body can be opened and the first pump body and the valve body 132 can be closed. When only cleaning liquid is needed, the first pump body and the valve body 132 can be opened and the second pump body can be closed, making the cleaning method more applicable.

[0177] For example, the cleaning device may be a cleaning robot, which can use a driving member to deliver the cleaning liquid in the box body 100 to the wet cleaning parts of the cleaning robot, so that the wet cleaning parts are soaked with the cleaning liquid to improve the cleaning strength of the wet cleaning parts. The cleaning device may also use a cleaning base station, which can serve the cleaning robot and clean the wet cleaning parts of the cleaning robot. During cleaning, the switching of the first pump body and the second pump body can be controlled according to the required cleaning liquid concentration to control the ratio of cleaning liquid and clean water delivered to the confluence pipe, thereby preparing the cleaning liquid of the appropriate concentration. After the cleaning liquid cleans the wet cleaning parts, the first pump body and valve body 132 can be closed and the second pump body can be opened to clean the wet cleaning parts using only clean water.

[0178] Example 2

[0179] Taking into account that cleaning equipment needs to store liquid through a liquid storage mechanism, such as storing clean water or sewage through a liquid storage mechanism, users need to inject clean water into the liquid storage mechanism, pour liquid or clean the liquid storage mechanism. The cover of the water tank in traditional technology is easy to shake, or even accidentally rotate and buckle on the water tank during the user's water filling process, which brings inconvenience to the user and low user experience.

[0180] As shown in Figures 2 to 7, according to the third aspect of an embodiment of the present application, a liquid storage mechanism is proposed, including: a box assembly 110; a cover assembly 120, the cover assembly 120 includes a cover plate 121, the cover plate 121 can be rotated relative to the box assembly 110 to cover or expose the inner cavity of the box assembly 110; a suspension member 130, the suspension member 130 is connected to the cover plate 121 or the box assembly 110, and the suspension member 130 is used to keep the cover plate 121 in a suspended state when it is rotated to a certain angle relative to the box assembly 110.

[0181] The liquid storage mechanism provided in the embodiment of the present application includes a box assembly 110, a cover assembly 120 and a suspension member 130. The cover assembly 120 includes a cover plate 121. Based on this, during use, the box assembly 110 can store cleaning liquid or clean water for cleaning, and can also be used to store sewage. During normal use, the cover plate 121 can seal the box assembly 110 to prevent the evaporation of the cleaning liquid or clean water, so as to reduce the spread of sewage odor. When the user needs to inject clean water, pour liquid or clean the box assembly 110, the cover 121 can be opened to rotate the cover 121 to a certain angle relative to the box assembly 110, and then the cover 121 is suspended by the suspension member 130, that is, the cover 121 can be fixed in the open position by the suspension member 130, and the cover 121 will not shake or close unexpectedly. In this case, the user can directly inject water, pour liquid or clean the box assembly 110, and the user does not need to hold the cover 121, which can free the user's hands and improve the user experience.

[0182] It can be understood that the rotation of the cover 121 to a certain angle relative to the box assembly 110 means that the cover 121 is rotated relative to the box assembly 110 to open the inner cavity of the box assembly 110, so as to facilitate the user to inject liquid into the box assembly, facilitate the user to pour liquid, and facilitate the user to clean the inner cavity of the box assembly 110. For example, the rotation angle can be 50°, 60°, 73°, 90°, 135°, etc., and the specific rotation angle is not limited in this application.

[0183] As shown in Figures 3 and 7, in a feasible embodiment, the suspension member 130 includes: a suspension arm 131, the suspension arm 131 is connected to the cover plate 121, the suspension arm 131 is made of elastic material, and when the cover plate 121 rotates to a certain angle relative to the box assembly 110, the suspension arm 131 is used to abut against the box assembly 110 to keep the cover plate 121 in a suspended state.

[0184] In this technical solution, the structural composition of the suspension member 130 is further provided. The suspension member 130 may include a suspension arm 131. When the cover 121 rotates to a certain angle relative to the box assembly 110, the cover 121 is in an open state. One end of the suspension arm 131 can abut against the box assembly 110. The gravity of the cover 121 is applied to the box assembly 110 through the suspension arm 131. The suspension arm 131 can maintain the cover 121 in an open state. In this case, the user can inject liquid into the box assembly 110, clean the box assembly 110, or pour water. The cover 121 will not be accidentally closed, which can improve the user experience.

[0185] In this technical solution, after the user completes the injection of liquid or the cleaning of the box assembly 110, the user can provide external force to the cover 121 by pressing the cover 121. Since the suspension arm 131 is made of elastic material, the external force can cause the suspension arm 131 to deform, thereby losing the contact with the box assembly 110, and the cover 121 can be smoothly covered on the box assembly 110. Based on this, the cover 121 can be suspended by the suspension arm 131, and the covering of the cover 121 is facilitated. The suspension arm 131 is a mechanical structure. On the one hand, the failure rate is low, which can ensure the stability of the suspension and covering of the cover 121; on the other hand, it makes the structure of the liquid storage mechanism simpler, more convenient for the production and processing of the liquid storage mechanism, and can reduce the cost of the liquid storage mechanism.

[0186] As shown in FIG. 2 , FIG. 3 , FIG. 6 and FIG. 7 , in a feasible embodiment, one end of the suspension arm 131 is connected to the cover plate 121 , and the other end is a free end.

[0187] In this technical solution, the style of the hovering arm 131 is further improved. The hovering arm 131 can be arc-shaped. Such a setting enables the shape of the hovering arm 131 to adapt to the movement trajectory of the cover 121 when it is opened or closed. The arc-shaped design can reduce the probability of interference between the hovering arm 131 and other components, and at the same time can reduce the size of the hovering part 130 as much as possible, which is convenient for production and processing and more beautiful.

[0188] In this technical solution, one end of the suspension arm 131 is connected to the cover 121, and the other end is a free end. Based on this, the connection between the suspension arm 131 and the cover 121 can be more reliable. When the cover 121 is opened, the suspension arm 131 can be abutted against the box assembly 110 through the free end. The gravity of the cover 121 is borne by the suspension arm 131 and the box assembly 110, and the cover 121 can be maintained in an open state. In this case, the user can inject liquid into the box assembly 110 or clean the box assembly 110. The cover will not be accidentally closed, which can improve the user experience.

[0189] In a feasible embodiment, the suspension arm 131 is arc-shaped, and the arc of the suspension arm 131 is 3° to 90°.

[0190] In this technical solution, the curvature of the hovering arm 131 is further provided. By selecting the curvature of the hovering arm 131 from 3° to 90°, when the cover 121 is in the open state and the hovering arm 131 is hovering, the cover 121 can have a sufficient opening angle to facilitate the user to inject liquid into the box assembly 110 or clean the inside of the box assembly 110; at the same time, the opening stroke of the cover 121 is controlled within a reasonable range to avoid the user from swinging the cover 121 significantly, increasing the amount of operation, and further improving the user experience.

[0191] It is understandable that if the curvature of the hovering arm 131 is less than 3°, then when the cover 121 is in the open state and is hovering by the hovering arm 131, the opening angle of the cover 121 may be small, and it is inconvenient for the user to fill water; if the curvature of the hovering arm 131 is greater than 90°, then during the opening process of the cover 121, it may be necessary to swing the cover 121 at a large angle, the user will over-operate, the movement amplitude is large, and the user experience is low.

[0192] As shown in Figures 3 and 7, in a feasible embodiment, the free end of the suspension arm 131 away from the cover plate 121 is inclined toward the wall of the box assembly 110 to form an abutment portion 132, which is used to abut against the box assembly 110.

[0193] In this technical solution, a style of a suspension arm 131 is further provided, and the free end of the suspension arm 131 can be tilted toward the direction of the wall of the box assembly 110, that is, the free end of the suspension arm 131 is tilted outward to form an abutment portion 132. Based on this, when the cover 121 is in the open state, the abutment portion 132 can abut on the box assembly 110, and the cover 121 can be fixed in the open position by the suspension arm 131. The cover 121 will not shake or close unexpectedly. In this case, the user can directly fill water into the box assembly 110 or clean the box assembly 110. The user does not need to hold the cover 121, which can free the user's hands and improve the user experience.

[0194] As shown in FIG. 2 and FIG. 6 , in a feasible embodiment, the box assembly 110 includes: a shell 111 ; a bracket 112 , the bracket 112 is connected to the shell 111 , the cover 121 is hinged to the bracket 112 , and the suspension arm 131 is used to abut against the bracket 112 .

[0195] In this technical solution, the structural composition of the box assembly 110 is further provided. The box assembly 110 may include a shell 111 and a bracket 112. A storage space may be formed inside the shell 111 to store cleaning liquid, clean water or sewage, and a bracket 112 may be provided on the shell 111. The bracket 112 is further connected to the cover 121, and the suspension arm 131 is also used to abut against the bracket 112. With such an arrangement, when assembling the liquid storage mechanism, the cover 121, the suspension arm 131 and the bracket 112 may be assembled first, and then the bracket 112 may be arranged on the shell 111. With such an arrangement, the cover 121, the suspension arm 131 and the bracket 112 may be assembled modularly first, and then assembled onto the shell 111, which facilitates the assembly of the liquid storage mechanism.

[0196] In a feasible embodiment, the suspension arm 131 and the cover plate 121 are an integrated structure.

[0197] In this technical solution, the suspension arm 131 and the cover plate 121 are an integrated structure. On the one hand, the overall mechanical strength of the cover plate 121 and the suspension member 130 is increased, which can improve the service life of the liquid storage mechanism; on the other hand, the cover plate 121 and the suspension arm 131 can be produced and processed simultaneously through one process, which has lower production costs. For example, the cover plate 121 and the suspension arm 131 can be formed through an injection molding process.

[0198] In a feasible embodiment, the suspension arm 131 is made of a resin material. This configuration allows the suspension arm 131 to have a certain degree of elasticity and strong mechanical strength, thereby increasing the service life of the liquid storage mechanism.

[0199] As shown in FIG7 , in a feasible embodiment, the liquid storage mechanism further includes: a guide groove 140 formed on the box assembly 110 to guide the hovering arm 131 when the cover 121 is subjected to external force, so that the cover 121 is out of the hovering state.

[0200] In this technical solution, the liquid storage mechanism may further include a guide groove 140, which is formed on the box assembly 110. When the cover 121 is in the open state, the suspension arm 131 abuts against the guide groove 140. When the cover 121 is not subjected to external force, the cover 121 can be in a suspended state. When the cover 121 is subjected to external force, such as when the user presses the cover 121, the guide groove 140 can guide the suspension arm 131, and the suspension arm 131 will shrink and deform in a direction away from the box assembly 110. The cover 121 can be covered on the box assembly 110. Based on this, the design of the guide groove 140 makes the closing of the cover 121 smoother.

[0201] It is understandable that when the box assembly 110 of the liquid storage mechanism includes a bracket 112 , the guide groove 140 can be formed on the bracket 112 .

[0202] As shown in FIG7 , in a feasible embodiment, the cover assembly 120 further includes: a fixing plate 122 , which is connected to the box assembly 110 and covers a partial area of ​​the box assembly 110 ; wherein the cover plate 121 is hinged to the fixing plate 122 .

[0203] In this technical solution, a style of the cover assembly 120 is further provided. The cover assembly 120 may include a cover plate 121 and a fixing plate 122. The fixing plate 122 may shield a partial area of ​​the box assembly 110. Based on this, when the cover plate 121 is opened, the moving stroke of the cover plate 121 is shorter, and the user operation is more convenient.

[0204] In a feasible embodiment, the suspension member 130 includes a damping member, the cover plate 121 is hinged to the fixing plate 122 via a rotating shaft, and the damping member is disposed on the rotating shaft.

[0205] In this technical solution, another style of the suspension member 130 is provided. The suspension member 130 may include a damping member, which is arranged on the rotating shaft connected to the cover 121. Based on this, when the cover 121 is opened at a certain position, the damping member will provide friction for the rotating shaft, thereby locking the rotating shaft, so that the cover 121 is suspended. When the cover 121 needs to be closed, the cover 121 will overcome the friction force under the external force, and the cover 121 can drive the rotating shaft to rotate. The cover is arranged on the box assembly 110, such as the cover 121 drives the rotating shaft to rotate 65 degrees, and When the external force on the cover 121 is removed, the damping member will lock the cover 121. When the cover 121 is pressed, the cover 121 overcomes the friction of the damping member, and the cover 121 is closed on the box assembly 110. In this way, the cover 121 can be fixed in the open position by the suspension member 130, and the cover 121 will not shake or close unexpectedly. In this case, the user can directly fill water into the box assembly 110 or clean the box assembly 110. The user does not need to hold the cover 121, which can free the user's hands and improve the user experience.

[0206] As shown in FIG. 2 , FIG. 4 and FIG. 6 , in a feasible embodiment, there are two or more suspension members 130 .

[0207] In this technical solution, the number of the suspension members 130 is further provided. There are two or more suspension members 130 . Such a configuration makes the suspension of the cover 121 more reliable.

[0208] In some examples, there may be two suspension members 130 , and the two suspension members 130 are symmetrically arranged along the central axis of the cover plate 121 . Such an arrangement can make the suspension force of the cover plate 121 more balanced and the suspension effect better.

[0209] In a possible embodiment, the arc of the hovering arm is 70° to 75°.

[0210] In this technical solution, the curvature of the hovering arm is further provided. By selecting the curvature of the hovering arm 131 to be 70° to 75°, when the cover 121 is in the open state and the hovering arm 131 is hovering, the cover 121 can have a sufficient opening angle to facilitate the user to inject liquid into the box assembly 110 or clean the inside of the box assembly 110; at the same time, the opening stroke of the cover 121 is controlled within a reasonable range to avoid the user from swinging the cover 121 significantly, increasing the amount of operation, and further improving the user experience.

[0211] It is understandable that if the curvature of the hovering arm 131 is less than 70°, then when the cover 121 is in the open state and is hovering by the hovering arm 131, the opening angle of the cover 121 may be small, and it is inconvenient for the user to fill water; if the curvature of the hovering arm 131 is greater than 75°, then during the opening process of the cover 121, it may be necessary to swing the cover 121 at a large angle, the user will over-operate, the movement amplitude is large, and the user experience is low.

[0212] As shown in FIG. 2 to FIG. 7 , according to a fourth aspect of an embodiment of the present application, a cleaning device is proposed, comprising: a liquid storage mechanism as in any of the above technical solutions.

[0213] The cleaning device provided in the embodiment of the present application includes a liquid storage mechanism as in any of the above technical solutions, and therefore the cleaning device has all the beneficial effects of the liquid storage mechanism of the above technical solutions.

[0214] The liquid storage mechanism of the cleaning device provided in the embodiment of the present application includes a box assembly 110, a cover 121 and a suspension member 130. Based on this, during use, the box assembly 110 can store cleaning liquid or clean water for cleaning, and can also be used to store sewage. During normal use, the cover 121 can cover the box assembly 110 to prevent the evaporation of the cleaning liquid or clean water, so as to reduce the spread of the odor of the sewage. When the user needs to inject clean water into the box assembly 110, pour liquid or clean the box assembly 110, the cover 121 can be opened. The cover 121 is suspended by the suspension member 130, that is, the cover 121 can be fixed in the open position by the suspension member 130, and the cover 121 will not shake or close unexpectedly. In this case, the user can directly inject water into the box assembly 110 or clean the box assembly 110 without holding the cover 121, which can free the user's hands and improve the user experience.

[0215] In some examples, the cleaning device may include a base station and a cleaning robot. The liquid storage mechanism is used to be arranged on the base station to store cleaning water or sewage, and the cleaning robot can clean the cleaning parts with clean water.

[0216] Example 3

[0217] Considering that existing heaters usually need to have a larger volume to ensure heating efficiency to ensure sufficient contact and heat exchange between the heating media, a larger installation space is required, which is not conducive to achieving a miniaturized design of the entire equipment.

[0218] In a fifth aspect, this embodiment provides a heater. Figure 8 is a schematic diagram of the structure of a heater provided by this embodiment. Figure 9 is a diagram of a heater in use provided by this embodiment.

[0219] As shown in Figures 8 and 9, the heater 1 of this embodiment includes a water inlet 2 and a water outlet 4. When the heater 1 is in use, the water inlet 2 is higher than the water outlet 4.

[0220] In some examples, referring to Figures 8 and 9 , a heater 1 includes a housing, with a water inlet 2 and a water outlet 4 disposed thereon. Multiple heating tubes are disposed within the housing. After the heated medium enters the heater housing through the water inlet 2 and flows autonomously toward the water outlet 4, it fully contacts and exchanges heat with the multiple heating tubes, achieving a higher temperature. The use of multiple heating tubes in the heater 1 of this embodiment facilitates further reducing the external dimensions of the heat exchanger 1.

[0221] For example, referring to Figure 8, the electric heating tube uses an aluminum die-cast electric heating tube. The aluminum die-cast electric heating tube has better structural strength and corrosion resistance, and has good thermal conductivity. In addition, the aluminum die-cast electric heating tube is lighter, which helps to reduce the overall weight of the heater.

[0222] For example, referring to FIG8 , a guide plate may be provided in the shell of the heater 1 to further slow down the flow rate of the medium to be heated and extend the flow path of the medium to be heated, thereby improving the heat exchange efficiency between the medium to be heated and the electric heating tube.

[0223] In some examples, referring to Figures 8 and 9, the heater 1 is box-shaped, including a bottom surface, a top surface, and side surfaces. The bottom surface and the top surface are parallel to each other, and the side surfaces are connected between the top surface and the bottom surface, forming a box shape. This arrangement makes the appearance of the heater 1 more regular and convenient for installation and arrangement. However, it should be noted that in other embodiments, the heater 1 may also adopt other regular shapes, or may also adopt an irregular shape. The specific shape can be designed according to the installation space and usage requirements, and this embodiment does not impose too many restrictions on this.

[0224] The heater 1 provided in this embodiment includes a water inlet 2 and a water outlet 4. When the heater 1 is in use, the water inlet 2 is higher than the water outlet 4. Since the water inlet 1 is higher than the water outlet 4, the medium to be heated can flow toward the water outlet 4 autonomously under the action of its own gravity after entering the heater 1 from the water inlet 2, without the need for external force. Moreover, during the autonomous flow of the medium to be heated, it can fully contact the heating components in the heater 1 to ensure the heat exchange effect, which is conducive to improving the heating efficiency. Therefore, the heater 1 provided in this application can reduce the external dimensions while achieving better heating efficiency, thereby facilitating the miniaturization design of the equipment.

[0225] In some embodiments, as shown in Figures 8 and 9, the water inlet 2 is provided with a water inlet joint 3. The water outlet 4 is provided with a water outlet joint 5. The direction of water flow in the water inlet joint 3 is parallel to the direction of water flow in the water outlet joint 5.

[0226] In some examples, referring to FIG8 and FIG9 , the water inlet connector 3 and the water outlet connector 5 can be any one of an external threaded end connector, a ferrule connector, and a self-fixing connector, and this embodiment does not impose too many restrictions on this.

[0227] It should be noted that the water inlet connector 3 and the water outlet connector 5 may be the same or different.

[0228] The water flow direction in the water inlet joint 3 of this embodiment is parallel to the water flow direction in the water outlet joint 5 , which is beneficial for making the water flow inside the heater 1 smoother and more stable, thereby improving the heating efficiency of the heater 1 .

[0229] In some embodiments, as shown in FIG. 8 and FIG. 9 , the water inlet 2 and the water outlet 4 are located on the same side of the heater 1 .

[0230] In some examples, as shown in Figures 8 and 9 , a deflector is provided within heater 1, located between water inlet 2 and water outlet 4. After cold water enters heat exchanger 1 through water inlet 2, it is guided by the deflector toward the side away from water inlet 2. There, it bypasses the deflector and flows back toward water outlet 4. This arrangement extends the cold water's flow path, further ensuring that the cold water is adequately heated.

[0231] In some examples, as shown in Figures 8 and 9 , the water inlet 2 and the water outlet 4 can be located on the front, rear, left, or right side of the heater 1. This embodiment does not impose any additional limitations on this. Preferably, as shown in Figures 8 and 9 , the water inlet 2 and the water outlet 4 are located on the front side of the heater 1. This arrangement facilitates the layout of the inlet and outlet pipes.

[0232] In this embodiment, the water inlet 2 and the water outlet 4 are located on the same side of the heater 1 , which reduces the difficulty of arranging the water inlet and outlet pipes and facilitates the overall installation and layout of the heater 1 .

[0233] In some embodiments, as shown in FIG. 8 and FIG. 9 , the water inlet 2 and the water outlet 4 are arranged alternately.

[0234] It is understood that the staggered arrangement of the water inlet 2 and the water outlet 4 means that when the heater 1 is in use, the water inlet 2 and the water outlet 4 do not correspond to each other in the vertical direction, that is, the water inlet 2 and the water outlet 4 are close to the left and right sides of the heater 1 respectively.

[0235] In some examples, as shown in Figures 8 and 9, the water inlet 2 is located near the right side of the heater 1, and the water outlet 4 is located near the left side of the heater 1. There is a certain distance between the two. This arrangement allows the cold water entering the heater 1 through the water inlet 2 to be fully heated.

[0236] It is understandable that, in other embodiments, the water inlet 2 may be arranged at a position close to the left side of the heater, and the water outlet 4 may be arranged at a position close to the right side of the heater 1 .

[0237] In this embodiment, the water inlet 2 and the water outlet 4 are arranged alternately and the water inlet 2 is higher than the water outlet 4, which can extend the flow path of the medium to be heated and thereby improve the heat exchange efficiency between the medium to be heated and the electric heating tube.

[0238] In some embodiments, as shown in FIG8 and FIG9 , the water inlet 2 is close to the top surface of the heater 1 , and the water outlet 4 is close to the bottom surface of the heater 1 .

[0239] The water inlet 2 of this embodiment is close to the top surface of the heater 1, and the water outlet 4 is close to the bottom surface of the heater 1, so that the water inlet 2 and the water outlet 4 have a large drop in the vertical direction, which can enable the medium to be heated to flow toward the water outlet 4 independently under the action of its own gravity, and is conducive to extending the flow path of the medium to be heated, further improving the heat exchange efficiency between the medium to be heated and the electric heating tube.

[0240] In some embodiments, as shown in FIG8 , the heater 1 further includes a thermostat 6 connected to the heater 1 . The thermostat 6 is used to control the heating temperature of the heater 1 .

[0241] In some examples, referring to FIG8 , the thermostat 6 can be a snap-action thermostat, a hydraulic expansion thermostat, a pressure thermostat, an electronic thermostat, a digital thermostat, etc. This embodiment does not impose too many restrictions on this.

[0242] In some examples, referring to FIG8 , the thermostat 6 further includes a temperature probe or thermocouple. The thermostat 6 converts the electrical signal fed back by the temperature probe or thermocouple into a temperature value, and controls the heater 1 to be turned on and off according to the set temperature value to achieve the purpose of controlling the temperature range.

[0243] This embodiment provides protection for heater 1 by providing a thermostat 6 with a recoverable temperature. When the temperature of heater 1 reaches the upper temperature limit of thermostat 6, thermostat 6 disconnects the power supply to heater 1, preventing further heating. This prevents overheating and damage to heater 1 while also saving energy. When the temperature of heater 1 falls below the lower temperature limit of thermostat 6, thermostat 6 reconnects the power supply to heater 1, preventing the water temperature in heater 1 from falling too low.

[0244] In some embodiments, as shown in FIG8 , the heater 1 further includes a fuse 7 . The fuse 7 is connected in series with the heater 1 . The fuse 7 is used to prevent the heater 1 from overheating.

[0245] In some examples, referring to FIG8 , the fuse 7 can be a flat-head tubular fuse, a pointed-head tubular fuse, a guillotine fuse, a spiral fuse, a blade fuse, a flat-plate fuse, a wrap-around fuse, a chip fuse, etc. This embodiment does not impose too many restrictions on this.

[0246] The heater 1 of this embodiment also includes a fuse 7, which provides a second layer of protection for the heater 1. If the thermostat 6 fails, the heating temperature of the heater 1 will continue to rise. When the heating temperature of the heater 1 reaches the melting point of the fuse 7, the fuse 7 will automatically open, cutting off the heating power supply to the heater 1 and protecting the heater 1 from overheating and safety risks.

[0247] In some embodiments, referring to FIG8 and FIG9 , the heater 1 is a resistance wire heater.

[0248] In some examples, as shown in Figures 8 and 9 , heater 1 is internally provided with an electric heating tube, and a resistance wire is disposed within the heating tube. Furthermore, to prevent electrical conduction, an insulating layer is provided between the resistance wire and the tube wall. This arrangement allows the resistance wire to generate heat when energized, and this heat energy is transferred to the tube wall of the heating tube, thereby heating the water in heater 1.

[0249] For example, the inner wall surface of the electric heating tube is plated with an insulating layer and / or the resistance wire is wrapped with an insulating layer.

[0250] In some examples, as shown in Figures 8 and 9 , a water channel is provided within heater 1, connecting between water inlet 2 and water outlet 4. A resistance wire is positioned along the water channel. This arrangement allows the heat generated by the resistance wire upon energization to heat the water in the water channel along its path. It will be appreciated that to ensure efficient heating, the water channel is arranged in a circuitous pattern within the heater.

[0251] The heater 1 of this embodiment adopts a resistance wire heater, which is conducive to precise control of the heating temperature, and has a uniform heating effect, high thermal efficiency, and a wide range of applications.

[0252] In a sixth aspect, this embodiment provides a water heater. Referring to FIG. 8 , the water heater includes the heater 1 in the above embodiment.

[0253] In some examples, the water heater also includes an inner tank, a preheater, a temperature control valve, and a thermostatic valve. The preheater is used to heat the water in the inner tank to a higher temperature. The temperature control valve is used to extract an appropriate amount of high-temperature water from the inner tank according to the user's set usage temperature, mix it with cold water, and then send it to heater 1. After being instantly heated by heater 1, it flows to the thermostatic valve. The thermostatic valve mixes the hot water output from heater 1 with cold water to the set temperature and outputs it to the user end to achieve a constant temperature effect.

[0254] In some examples, referring to FIG8 , the water heater may include multiple heaters 1. Each heater 1 has a different heating temperature. This arrangement enables the water heater to instantly switch to water of different temperatures according to the user's selection.

[0255] The water heater provided in this embodiment includes the above-mentioned heater 1, so it can have a smaller volume while ensuring heating efficiency, reducing the demand for installation space, and can be applied to more application scenarios.

[0256] In a seventh aspect, this embodiment provides a base station. Figure 10 is a schematic structural diagram of a base station provided by this embodiment.

[0257] Referring to Figures 8-10 , the base station includes a cleaning water tank and the heater 1 described in the above embodiment. The cleaning water tank is used to store cleaning water. The water inlet 2 of the heater 1 is in fluid communication with the cleaning water tank. The heater 1 is used to instantly heat the cleaning water output from the cleaning water tank and output it through the water outlet 4.

[0258] In some examples, see Figures 8-10 . The water outlet of the cleaning water tank is connected to the water inlet of a heater, and the water outlet of the heater is connected to the cleaning chamber of a base station sweeper. The cleaning water from the cleaning water tank is immediately heated by the heater and then delivered to the base station sweeper cleaning chamber for cleaning the sweeper's mop. Using hot water to clean the sweeper's mop improves cleaning efficiency and effectiveness.

[0259] In some examples, referring to Figures 8-10 , the base station also includes a damping sensor. When the damping sensor detects that the resistance to the mop's rotation exceeds a preset value, indicating that the mop is stuck with debris that is difficult to clean, the damping sensor transmits a signal to the controller. Upon receiving the signal, the controller activates heater 1 to heat the cleaning water. After the mop is cleaned with the hot cleaning water, the damping of the mop's rotation decreases. The controller then deactivates heater 1 and rinses the mop with room temperature water until the mop is thoroughly clean.

[0260] In some examples, referring to Figures 8 to 10, the water outlet of the heater 1 may be further provided with a dosing device for mixing detergent into the cleaning water to further improve the cleaning effect of the mop of the sweeper.

[0261] The base station provided in this embodiment includes the aforementioned heater 1, which is used to heat the cleaning water output from the cleaning water tank in the base station, thereby improving the cleaning efficiency of the sweeper. Furthermore, because the base station in this embodiment utilizes the aforementioned heater 1, it has a smaller size, reduces its footprint, and can be placed in a smaller space.

[0262] Example 4

[0263] Considering that, in recent years, with the development of science and technology, various cleaning products have emerged one after another, which have reduced the burden of people's cleaning and sweeping work, met people's needs, and provided great convenience to people's lives. Among them, automatic cleaning equipment is loved by people for its highly intelligent characteristics.

[0264] The self-cleaning maintenance station can automatically provide clean water to clean the mop and then suck the cleaned sewage into the sewage bucket. However, the water supply pipeline is either improperly positioned, affecting the layout of other components, or too complicated to be stored, resulting in an unreasonable overall design of the self-cleaning maintenance station.

[0265] According to the eighth aspect of the embodiment of the present application, a self-cleaning maintenance station is proposed, including a maintenance station body, a clean water tank and a sewage tank, wherein the clean water tank and the sewage tank are assembled in the maintenance station body, wherein the maintenance station body includes: a clean water pipe assembly, connected to the clean water tank, configured to inject clean water into the clean water tank; a sewage pipe assembly, connected to the sewage tank, configured to drain the sewage from the sewage tank; a water pipe trough, arranged at one end of the maintenance station body near the bottom, configured to accommodate at least a portion of the clean water pipe assembly and / or at least a portion of the sewage pipe assembly.

[0266] At least a portion of the clean water pipe assembly and / or at least a portion of the sewage pipe assembly of the self-cleaning maintenance station provided in the embodiment of the present application is arranged in the water pipe groove at one end of the maintenance station body near the bottom, so that the layout of the clean water pipe assembly and the sewage pipe assembly is more reasonable, and the space at the bottom of the self-cleaning maintenance station is fully utilized, while avoiding occupying the spatial position of components such as heating components and water pump components, so that the arrangement of various components in the self-cleaning maintenance station is more reasonable and the appearance is neater.

[0267] Optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0268] As shown in FIG11 , an embodiment of the present disclosure provides a self-cleaning maintenance station. As an example, FIG11 is a schematic diagram of the overall structure of a self-cleaning maintenance station according to some embodiments of the present disclosure.

[0269] In order to more clearly describe the behavior of the self-cleaning maintenance station, the following directions are defined: the self-cleaning maintenance station can be calibrated by defining the following three mutually perpendicular axes: the transverse axis Y, the front-to-back axis X, and the central vertical axis Z. The direction opposite to the arrow along the front-to-back axis X, that is, the direction in which the automatic cleaning device enters the self-cleaning maintenance station, is marked as "rearward", and the direction along the arrow along the front-to-back axis X, that is, the direction in which the automatic cleaning device leaves the self-cleaning maintenance station, is marked as "forward". The transverse axis Y is essentially along the width of the self-cleaning maintenance station body. The direction of the arrow along the transverse axis Y is the "left side" of the self-cleaning maintenance station, and the direction opposite to the arrow along the transverse axis Y is the "right side" of the self-cleaning maintenance station. The vertical axis Z is the direction extending upward along the bottom surface of the self-cleaning maintenance station. The direction of the arrow along the vertical axis Z is the "upper side" of the self-cleaning maintenance station, and the direction opposite to the arrow along the vertical axis Z is the "lower side" of the self-cleaning maintenance station.

[0270] As shown in Figures 11 and 12, the self-cleaning maintenance station provided in this embodiment includes a self-cleaning maintenance station base plate 1000 and a self-cleaning maintenance station body 2000. The self-cleaning maintenance station base plate 1000 and the self-cleaning maintenance station body 2000 are detachably or non-detachably connected. The detachable connection facilitates the transportation and maintenance of the self-cleaning maintenance station base plate 1000 and the self-cleaning maintenance station body 2000. The self-cleaning maintenance station also includes a clean water tank 3000 and a sewage tank 4000. The clean water tank 3000 and the sewage tank 4000 are assembled in the maintenance station body 2000. The clean water tank 3000 is used to supply clean water to the cleaning tank of the self-cleaning maintenance station to clean the mop or roller brush on the cleaning equipment; the cleaned sewage enters the sewage tank for storage and is discharged from the self-cleaning maintenance station when the sewage tank is full.

[0271] As shown in Figures 11 and 12, the maintenance station body 2000 includes a clean water pipe assembly 2100, a sewage pipe assembly 2200, and a water pipe trough 2300. The clean water pipe assembly 2100 is connected to the clean water tank 3000 and is configured to inject clean water into the clean water tank 3000; the sewage pipe assembly 2200 is connected to the sewage tank 4000 and is configured to guide the sewage from the sewage tank 4000; the water pipe trough 2300 is provided at one end of the maintenance station body 2000 near the bottom, and the water pipe trough 2300 is provided at the bottom end of the maintenance station body 2000. The water pipe trough 2300 extends generally in the left-right direction of the maintenance station body 2000 and is configured to accommodate at least a portion of the clean water pipe assembly 2100 and / or at least a portion of the sewage pipe assembly 2200. The water pipe trough 2300 can accommodate at least a portion of the clean water pipe assembly 2100 or at least a portion of the sewage pipe assembly 2200. When widened, the water pipe trough 2300 can accommodate both the clean water pipe assembly 2100 and at least a portion of the sewage pipe assembly 2200. At least a portion of the clean water pipe assembly 2100 and / or at least a portion of the sewage pipe assembly 2200 is located behind the water pipe trough 2300. The horizontal projections of the clean water pipe assembly 2100 and the sewage pipe assembly 2200 do not extend beyond the horizontal projections of the maintenance station body 2000. This allows the clean water pipe assembly 2100 and / or the sewage pipe assembly 2200 to be completely concealed within the water pipe trough 2300, enhancing the appearance of the self-cleaning maintenance station.

[0272] In some embodiments, as shown in Figure 11, the maintenance station body 2000 also includes a back panel 2400, which is detachably arranged on the back of the maintenance station body 2000, and the lower edge of the back panel 2400 extends to the upper edge of the water pipe trough 2300, so that the water pipe trough 2300 is exposed to the outside of the self-cleaning maintenance station, which is convenient for manual storage of at least a portion of the clean water pipe assembly 2100 and / or at least a portion of the sewage pipe assembly 2200. Optionally, the two ends of the water pipe trough 2300 have a wider size to facilitate accommodating the first clean water pipe joint 2110 and the first sewage pipe joint 2210.

[0273] In some embodiments, as shown in Figure 11, the maintenance station body 2000 also includes at least one locking member 2310, which is located at the upper edge or lower edge of the water pipe groove 2300, and is used to lock at least a portion of the clean water pipe assembly and / or at least a portion of the sewage pipe assembly, for example, to lock the first clean water pipe 2120 and / or the first sewage pipe 2220 to prevent the first clean water pipe 2120 and / or the first sewage pipe 2220 from falling off from the water pipe groove 2300.

[0274] In some embodiments, as shown in FIG12 , the clean water pipe assembly 2100 includes a first clean water pipe connector 2110 disposed at one end of the water pipe trough 2300 adjacent to the clean water tank 3000; the sewage pipe assembly 2200 includes a first sewage pipe connector 2210 disposed at one end of the water pipe trough 2300 adjacent to the sewage tank 4000. The water inlet of the first clean water pipe connector 2110 and the water outlet of the first sewage pipe connector 2210 may face the same direction or opposite directions. In some embodiments, the first clean water pipe connector 2110 and the first sewage pipe connector 2210 located at one end of the water pipe trough 2300 are rotatable in the horizontal direction. For example, the water inlet of the first joint 2110 of the clean water pipe can be set to the left or right, and the water outlet of the first joint 2210 of the sewage pipe can also be set to the left or right. Accordingly, the first clean water pipe 2120 connected to the water inlet of the first joint 2110 of the clean water pipe can be snapped into the water pipe groove 2300, or rotated to another direction and not located in the water pipe groove 2300. Similarly, the first sewage pipe 2220 connected to the water outlet of the first joint 2210 of the sewage pipe can be snapped into the water pipe groove 2300, or rotated to another direction and not located in the water pipe groove 2300. This makes it convenient to reasonably arrange the positions of the first clean water pipe 2120 and the first sewage pipe 2220 according to the water inlet and sewage discharge positions.

[0275] In some embodiments, as shown in FIG12 , the clean water pipe assembly 2100 further includes a first clean water pipe 2120 connected to the first clean water pipe connector 2110; the sewage pipe assembly 2200 further includes a first sewage pipe 2220 connected to the first sewage pipe connector 2210; and the first clean water pipe 2120 and / or the first sewage pipe 2220 are snap-fitted into the water pipe trough 2300. Specifically, only the first clean water pipe 2120 may be snap-fitted into the water pipe trough 2300, or only the first sewage pipe 2220 may be snap-fitted into the water pipe trough 2300, or both the first clean water pipe 2120 and the first sewage pipe 2220 may be snap-fitted into the water pipe trough 2300. This facilitates the proper arrangement of the first clean water pipe 2120 and the first sewage pipe 2220 according to the water inlet and sewage outlet locations. The diameter of the first sewage pipe 2220 should be larger than that of the first clean water pipe 2120 because the first sewage pipe 2220 needs to output sewage to prevent garbage in the sewage from getting stuck in the first sewage pipe 2220. Optionally, the first sewage pipe 2220 and the first clean water pipe 2120 are formed of hard materials.

[0276] In some embodiments, as shown in FIG12 , the clean water pipe assembly 2100 further includes a clean water pipe second connector.

[0277] A second clean water pipe connector 2130 is provided at the top of the maintenance station body 2000. A water inlet solenoid valve 2140 is provided between the second clean water pipe connector 2130 and the clean water tank 3000. One end of the second clean water pipe connector 2130 extends into the water inlet solenoid valve 2140 and communicates with the water inlet solenoid valve 2140. A second clean water pipe 2150 is connected between the first clean water pipe connector 2110 and the second clean water pipe connector 2130. The second clean water pipe 2150 is generally vertically disposed at an edge or corner of the maintenance station body 2000. The second clean water pipe 2150 is formed of a hard material to facilitate vertical positioning without bending.

[0278] In some embodiments, the maintenance station body 2000 further includes a stopper 2160, which is disposed on the inner sidewall of the maintenance station body 2000 housing and abuts against the outer end of the second clean water pipe connector 2130. The stopper 2160 is configured to apply an external force toward the water inlet solenoid valve 2140 to the second clean water pipe connector 2130 to prevent the second clean water pipe connector 2130 from separating from the water inlet solenoid valve 2140 due to water pressure after the water inlet solenoid valve 2140 is closed. Optionally, an assembly gap is provided between the stopper 2160 and the second clean water pipe connector 2130.

[0279] In some embodiments, as shown in Figure 14, the clean water pipe assembly 2100 also includes a third clean water pipe joint 2170, which is connected to the first clean water pipe joint 2110 and is used to change the direction of water flow, for example, changing the horizontal water flow to the vertical water flow; the clean water pipe assembly 2100 also includes a positioning member 2180, which is arranged on the outside of the third clean water pipe joint 2170, for example, fixed by at least one screw, and the positioning member 2180 is used to fix the third clean water pipe joint 2170 to prevent the third clean water pipe joint 2170 from being separated from the first clean water pipe joint 2110 under water pressure.

[0280] In some embodiments, as shown in Figures 11 and 15, the sewage pipe assembly 2200 further includes a second sewage pipe connector 2230, which is disposed at the top of the maintenance station body and communicates with the sewage tank 4000 and can serve as the outlet connector of the sewage tank 4000; a water diversion pipe 2240, which is, for example, a Y-shaped structure and has a first water inlet, a second water inlet, and a water outlet, the outlet being connected to the first sewage pipe connector 2210; and a second sewage pipe 2240, which is disposed between the first water inlet and the second sewage pipe connector 2230. The sewage pipe assembly 2200 further includes a third sewage pipe 2250, which is disposed between the second water inlet and the overflow outlet of the sewage tank 4000. Sewage from sewage tank 4000 is discharged through sewage pipe second connector 2230, second sewage pipe 2240, first sewage pipe connector 2210, and first sewage pipe 2220. Furthermore, when sewage tank 4000 is full, pumping into sewage tank 4000 may not stop due to, for example, a failure of the float valve. In this case, excess sewage can be discharged from the overflow port of sewage tank 4000. Sewage from third sewage pipe 2250 and second sewage pipe 2240 then converges in diversion pipe 2260 before being discharged through first sewage pipe 2220. This prevents sewage from overflowing into the self-cleaning maintenance station and damaging other components of the station.

[0281] In some embodiments, as shown in Figure 15, the sewage pipe assembly 2200 also includes a duckbill valve 2270, which is arranged at the overflow outlet of the sewage tank 4000 to prevent sewage from flowing back. The outlet of the duckbill valve 2270 is usually a one-way flat-mouth structure. When water flows into the inlet of the duckbill valve 2270, it will flush the flat-mouth structure of the outlet and flow out.

[0282] According to the ninth aspect of the embodiment of the present application, a maintenance system is proposed, including an automatic cleaning device and a self-cleaning maintenance station as described above. The automatic cleaning device enters the self-cleaning maintenance station to perform mop cleaning. For related content, please refer to the relevant technology and will not be repeated here.

[0283] At least a portion of the clean water pipe assembly and the sewage pipe assembly of the self-cleaning maintenance station disclosed herein are moved from a water pipe groove arranged at one end of the maintenance station body near the bottom, making the layout of the clean water pipe assembly and the sewage pipe assembly more reasonable, making full use of the space at the bottom of the self-cleaning maintenance station, and avoiding occupying the spatial position of components such as heating components and water pump components, so that the arrangement of various components in the self-cleaning maintenance station is more reasonable and the appearance is neater.
