Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cleaning equipment, in particular to a sealing element, a plug-in connection structure, a cleaning base station and a cleaning equipment. Background Art
[0002] At present, the tray of the cleaning base station can be used to clean the rag of the sweeping robot. After cleaning, sewage will remain in the tray. The cleaning base station will drain the sewage and pump water from the tray through the sewage pipe. The tray is inserted into the sealing ring in the sewage pipe through a tube to achieve sealing. After the sewage is pumped out, when the user takes out the tray for cleaning, the tube is separated from the sealing ring. Since there are still water droplets on the inner wall of the sewage pipe, the water droplets will flow downward under the action of gravity, and since the inner wall of the sealing ring is relatively smooth, the water droplets will easily flow along the inner wall of the sealing ring. The remaining water droplets will flow out of the sealing ring and drip onto the base to contaminate the base, thereby affecting the user experience. Utility Model Content

[0042] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0043] Reference Figure 4 As shown, the plug connection structure 1000 provided by the embodiment of the utility model comprises a plug tube 100, a connector 200 and a first sealing member 300. The connector 200 is provided with a channel 210, and at least part of the structure of the first sealing member 300 is located in the channel 210. The entire structure of the first sealing member 300 may be located in the channel 210, or part of the structure of the first sealing member 300 may be located in the channel 210. The outer peripheral wall of the first sealing member 300 is tightly fitted with the inner peripheral wall of the channel 210, thereby achieving sealing. Figures 1 to 3 As shown, the first sealing member 300 includes a main body 310 and a water retaining portion 320. The first sealing member 300 can be understood as a sealing ring structure. The main body 310 can be constructed as an annular structure, specifically a circular ring structure. The main body 310 is also provided with a first through hole 311. The axis of the first through hole 311 is the same as the axis of the main body 310. Figure 3 The axis L in the figure can also be understood as the axis of the first sealing member 300 .
[0044] Reference Figure 3As shown, the main body 310 and the water retaining part 320 can be connected as an integral structure, the water retaining part 320 is located in the first through hole 311, the water retaining part 320 is connected to the inner wall of the first through hole 311, the water retaining part 320 has a water retaining function, the water retaining part 320 can be constructed as an annular structure, the water retaining part 320 is arranged around the axis L, and the water retaining part 320 extends around the axis L for one circle, so as to ensure that the water retaining part 320 can effectively block the flow of water droplets. The water retaining part 320 can be understood as a petal-shaped structure, the water retaining part 320 has a folded state and an expanded state, the first sealing member 300 can produce a local deformation, so that the water retaining part 320 can switch between the folded state and the expanded state, it can also be understood that the connection between the main body 310 and the water retaining part 320 can produce a deformation, or it can also be understood that the water retaining part 320 can produce a deformation. Specifically, the first seal 300 can be made of rubber or other soft materials, so that the first seal 300 has a certain elastic force, so that the first seal 300 can produce a certain deformation, and the first seal 300 can be restored to its original state after deformation, so that the water retaining part 320 can automatically restore from the retracted state to the expanded state.
[0045] It should be noted that the plug connection structure 1000 has a plugged state and a separated state. In the plugged state, the cannula 100 is plugged into the first through hole 311 and the first sealing member 300 is stretched to the expanded state. The cannula 100 can keep the first sealing member 300 in the expanded state. At this time, the inner wall of the first through hole 311 is tightly fitted with the outer wall of the cannula 100, thereby achieving a sealed fit. Figure 4 As shown, the cannula 100 can be Figure 4 The plugging direction shown in the figure is inserted into the first through hole 311. In actual scenarios, the plugging direction can be horizontal or vertical. The plugging direction is the same as the direction of the axis L of the first through hole 311. When the plugging direction is vertical, the plugging tube 100 is inserted into the first through hole 311 from bottom to top, and the plugging tube 100 pushes the water retaining part 320 of the first sealing member 300 upward. In the separated state, the plugging tube 100 is separated from the first sealing member 300, and the plugging tube 100 no longer supports the water retaining part 320, and the water retaining part 320 can be restored from the expanded state to the retracted state.
[0046] It should also be noted that the plane perpendicular to the axis L of the first through hole 311 is defined as the reference plane. When the water retaining portion 320 is in the retracted state, the projected area of the water retaining portion 320 on the reference plane is the first area. When the water retaining portion 320 is in the expanded state, the projected area of the water retaining portion 320 on the reference plane is the second area, and the second area is smaller than the first area. It should be noted that the size of the projected area of the water retaining portion 320 on the reference plane is associated with the water retaining effect it produces. The larger the projected area, that is, the larger the area that hinders the flow of water droplets, the stronger the water retaining effect, and the smaller the projected area, which can facilitate the flow of water through the water retaining portion 320. In the retracted state, the projected area of the water retaining portion 320 is large, which can ensure a good water retaining effect. In the expanded state, the projected area of the water retaining portion 320 is small, which is conducive to the flow of water through the water retaining portion 320 and ensures normal water flow. When the water retaining portion 320 switches from the folded state to the expanded state, the projected area of the water retaining portion 320 on the reference plane gradually decreases, and when the water retaining portion 320 returns from the expanded state to the folded state, the projected area of the water retaining portion 320 on the reference plane gradually increases.
[0047] In this embodiment, the structure of the first sealing member 300 is improved, and a water retaining portion 320 is provided in the first through hole 311. Since the first sealing member 300 can be deformed, the water retaining portion 320 can switch between a retracted state and an expanded state. When the cannula 100 and the connector 200 need to be connected together, the cannula 100 can be inserted into the first through hole 311 of the first sealing member 300, and the cannula 100 can be allowed to open the first sealing member 300, and the first sealing member 300 can be changed from a retracted state to an expanded state, which can ensure that the cannula 100 and the channel 210 are normally connected, and ensure that the water flow can flow well between the cannula 100 and the channel 210. At this time, the flow direction of the water flow is the same as the plug-in direction of the cannula 100, and the water flow flows from the cannula 100 to the connector 200. When it is necessary to separate the cannula 100 and the connector 200, the cannula 100 can be directly pulled out, and the water retaining portion 320 can be restored from the expanded state to the retracted state. The water retaining portion 320 can block the water droplets remaining on the inner wall of the channel 210 from flowing along the inner wall of the first through hole 311, thereby playing a water retaining role and preventing the remaining water droplets from leaking out of the first sealing component 300.
[0048] It is understandable that the plug-in connection structure 1000 of this embodiment can be used in a cleaning base station. Figure 5 and Figure 6As shown, the cleaning base station 2000 provided by the embodiment of the utility model comprises the plug connection structure 1000, the pumping device 2100, the base and the tray 2200 of the above embodiment. The tray 2200 is installed in the base, and the tray 2200 and the base are connected and matched through the plug connection structure 1000. Specifically, the connector 200 of the plug connection structure 1000 is arranged in the base, and the cannula 100 of the plug connection structure 1000 is arranged in the tray 2200. The cannula 100 is passed through the tray 2200. The cannula 100 can be sealed with the tray 2200 through the second sealing member 2220. The second sealing member 2220 can be understood as a sealing ring. The second sealing member 2220 is sleeved on the outer periphery of the cannula 100, and the second sealing member 2220 is located between the cannula 100 and the tray 2200.
[0049] Reference Figure 5 and Figure 6 As shown, the pumping device 2100 is located above the tray 2200 and the base, and the pumping device 2100 includes a sewage tank 2110, a connecting pipe 2120 and a water pump 2130. The sewage tank 2110 is connected to the channel 210 of the connecting piece 200 through the connecting pipe 2120. The connecting pipe 2120 can be understood as a sewage hose. The tray 2200 is provided with a water storage tank 2210, and the intubation tube 100 is connected to the water storage tank 2210. The tray 2200 has a cleaning function. The water storage tank 2210 is used to store clean water. The clean water in the water storage tank 2210 can be used to clean the roller brush or rag of the sweeping robot 3000. The cleaning base station 2000 can include a clean water tank, which can clean the water storage tank in the tray 2200. 2210 provides clean water. After cleaning the roller brush or rag, the clean water in the water tank 2210 becomes sewage. The insert tube 100 can be understood as a sewage suction nozzle. When the tray 2200 is connected to the base, the insert tube 100 is inserted into the first sealing member 300. The water retaining portion 320 of the first sealing member 300 is stretched from a retracted state to an expanded state by the insert tube 100, so that the insert tube 100 connects the water tank 2210 with the sewage tank 2110. The water pump 2130 generates suction to suck the sewage in the water tank 2210 into the sewage tank 2110. The sewage tank 2110 can temporarily store a certain volume of sewage. The user does not need to frequently remove the tray 2200 to pour out the sewage in the water tank 2210, thereby improving the user experience. When the user removes the tray 2200 for cleaning, the insert tube 100 of the tray 2200 is separated from the first seal 300, and the water retaining portion 320 of the first seal 300 is restored from the expanded state to the retracted state. The water retaining portion 320 in the retracted state can play a water retaining role, preventing the water droplets remaining on the inner wall of the connecting tube 2120 from flowing out of the first seal 300, making it difficult for the residual water droplets to drip onto the base, thereby avoiding contamination of the base. In addition, since the residual water droplets are small in size, the residual water droplets will dry naturally after waiting for a period of time, and will not accumulate on the inner wall of the connecting tube 2120 for a long time.
[0050] It is understandable that, referring to Figure 4 and Figure 7 As shown, in some embodiments, the channel 210 includes a vertical section 211 and a horizontal section 212 that are connected to each other. The vertical section 211 extends in the up-down direction, and the horizontal section 212 extends in the horizontal direction. One end of the horizontal section 212 is connected to the lower end of the vertical section 211, and the connecting pipe 2120 is connected to the upper end of the vertical section 211. The first seal 300 is installed at the other end of the horizontal section 212. The axis of the first through hole 311 of the first seal 300 is arranged in the horizontal direction. The cannula 100 can be inserted into or detached from the first through hole 311 of the first seal 300 in the horizontal direction, that is, the tray 2200 can be disassembled and assembled to the base in the horizontal direction, which is convenient to operate. In addition, the residual water droplets in the channel 210 are generally accumulated at the bottom position of the horizontal section 212 due to the action of gravity. Since the water retaining portion 320 blocks the flow of water droplets, the water droplets can be prevented from flowing out of the first seal 300.
[0051] Reference Figure 5 As shown, it is a cleaning device 4000 provided by an embodiment of the utility model. The cleaning device 4000 includes the cleaning base station 2000 and the sweeping robot 3000 of the above embodiment. The cleaning base station 2000 can perform cleaning operations on the sweeping robot 3000. The sweeping robot 3000 is connected to the tray 2200. It can also be understood that the sweeping robot 3000 is placed on the tray 2200, so that the roller brush or rag of the sweeping robot 3000 contacts the clean water in the water tank 2210 of the tray 2200. Since the first sealing member 300 of the above embodiment is adopted in this embodiment, when the tray 2200 is removed for cleaning, the first sealing member 300 can play a water blocking role to prevent residual water droplets from dripping onto the base and contaminating the base, which can improve the user experience.
[0052] It should be noted that it is understandable that in some other embodiments, the plug-in connection structure 1000 can also be used to connect the sweeping robot 3000 and the cleaning base station 2000. For example, the cleaning base station 2000 includes a clean water tank, which is used to replenish clean water for the sweeping robot 3000. The sweeping robot 3000 is connected to the clean water tank through the plug-in connection structure 1000, and the intubation tube 100 is arranged on the water tank in the sweeping robot 3000. The channel 210 of the connecting member 200 is connected to the clean water tank. When water replenishment is needed, the intubation tube 100 is inserted into the water tank. Insert the first sealing member 300 in the connector 200, and the plug 100 opens the water retaining part 320 to the expanded state, so that the plug 100 connects the water tank in the sweeping robot 3000 with the clean water tank. At this time, the water in the clean water tank can be input into the water tank through the water pump 2130, so as to achieve water replenishment. After the water is replenished, the plug 100 is pulled out, and the water retaining part 320 of the first sealing member 300 can automatically return to the retracted state. The water retaining part 320 can prevent the residual water drops from flowing out of the first sealing member 300 along the inner wall of the first through hole 311 to avoid water leakage. Not limited to this, the plug connection structure 1000 of this embodiment can also be used to connect other different types of devices together. As long as the device is connected and matched by plugging the plug 100, the plug connection structure 1000 of this embodiment can be used, so as to achieve the effect of preventing water leakage.
[0053] It should also be noted that, in some embodiments, any structure that uses plug-in connection to achieve connection can be applied to the first sealing member 300 of the above embodiment.
[0054] It is understandable that, referring to Figure 1 As shown, in some embodiments, the water retaining portion 320 includes a plurality of retaining pieces 321, which are arranged at intervals along the circumference of the first through hole 311, and the retaining pieces 321 have a first end and a second end that are separated from each other, and the first end of the retaining piece 321 is connected to the inner wall of the first through hole 311, and the retaining piece 321 is connected to the main body 310 as an integral structure, and the second end of the retaining piece 321 is away from the inner wall of the first through hole 311. Specifically, there is a spacing between two adjacent retaining pieces 321, so that the connection between the retaining piece 321 and the inner wall of the first through hole 311 can produce a large deformation, which is conducive to the cannula 100 to open the retaining piece 321. The spacing between two adjacent retaining pieces 321 can be set to be smaller, and because water droplets have a certain surface tension, the water droplets will adhere to the surface of the retaining piece 321, which can ensure that the water droplets will not pass through the spacing between the two retaining pieces 321 and flow out of the first sealing member 300. When the number of the blocking pieces 321 is two, the blocking pieces 321 may be semicircular; when the number of the blocking pieces 321 is three or more, the blocking pieces 321 may be fan-shaped.
[0055] It is understood that in some embodiments, when the water retaining portion 320 is in the retracted state, the distance between two adjacent retaining pieces 321 ranges from 0.5 mm to 0.8 mm. The distance between the two retaining pieces 321 is ensured to be small, so that water droplets are not easy to pass through the gap between the two retaining pieces 321, and the relative movement of the two retaining pieces 321 is not hindered, which is conducive to the cannula 100 to open the retaining pieces 321. Specifically, the distance between the two retaining pieces 321 can be 0.5 mm, 0.6 mm, 0.7 mm or 0.8 mm.
[0056] It is understandable that, referring to Figure 3 As shown, in some embodiments, when the water retaining portion 320 is in the retracted state, the baffle 321 is inclined toward the inner wall of the first through hole 311, and the distance between the baffle 321 and the inner wall of the first through hole 311 gradually decreases from the second end of the baffle 321 to the first end of the baffle 321. When the cannula 100 is inserted into the first through hole 311, the cannula 100 is inserted into the first through hole 311 from the first end of the baffle 321 to the second end of the baffle 321, and the cannula 100 stretches the baffle 321 toward the inner wall of the first through hole 311. When the water retaining portion 320 is in the expanded state, the inclination of the baffle 321 is less than the inclination of the baffle 321 when the water retaining portion 320 is in the retracted state. It can also be understood that when the water retaining portion 320 is in the expanded state, the angle between the baffle 321 and the inner wall of the first through hole 311 is less than the angle between the baffle 321 and the inner wall of the first through hole 311 when the water retaining portion 320 is in the retracted state. In addition, when the axis of the first through hole 311 is set along the up and down direction, since the baffle 321 is set at an angle, the second end of the baffle 321 is located above the first end of the baffle 321. When the remaining water droplets flow from top to bottom along the inner wall of the first through hole 311, the water droplets will be blocked between the baffle 321 and the inner wall of the first through hole 311, making it difficult for the water droplets to pass over the second end of the baffle 321, thereby achieving a better water blocking effect.
[0057] It should also be noted that in the above embodiment, the baffle 321 is inclined along the pumping direction of the pumping device 2100, that is, the inclination direction of the baffle 321 is along the flow direction of the water flow, which can also be understood as the baffle 321 is inclined toward the flow direction of the water flow, so that the water flow can flow along the surface of the baffle 321, thereby reducing the water flow resistance and facilitating the flow of water. Figure 4 The plug-in direction is the same as in .
[0058] It is understandable that, referring to Figure 4As shown, in some embodiments, a guide surface 110 is provided at one end of the cannula 100, and the guide surface 110 is an inclined surface. When the cannula 100 is inserted into the first sealing member 300, the guide surface 110 abuts against the baffle 321. Since the guide surface 110 is an inclined surface, when the cannula 100 opens the baffle 321, the baffle 321 will gradually tilt toward the inner wall of the first through hole 311, so that the contact area between the baffle 321 and the guide surface 110 is larger, which can play a guiding role. When setting the slope of the guide surface 110, when the water retaining part 320 is in the unfolded state, the slope of the guide surface 110 can be made exactly the same as the slope of the baffle 321, thereby increasing the contact area between the guide surface 110 and the baffle 321 and providing a better support effect on the baffle 321.
[0059] It is understandable that, referring to Figure 1 As shown, in some embodiments, when the water retaining portion 320 is in the retracted state, a water outlet 322 is defined between the second ends of the plurality of baffles 321. The water outlet 322 is used to conduct the cannula 100 and the channel 210, which is conducive to the flow of water. The water outlet 322 can be circular, square or other shapes. The water outlet 322 is located in the middle of the water retaining portion 320. When the axis of the first sealing member 300 is horizontally arranged, the residual water droplets accumulate at the bottom of the first through hole 311 and are not easy to flow to the position of the water outlet 322. Therefore, the residual water droplets are not easy to pass through the water outlet 322. When the axis of the first sealing member 300 is vertically arranged, the baffle 321 of the water retaining part 320 can be tilted with reference to the above embodiment, so that the second end of the baffle 321 is higher than the first end of the baffle 321. At this time, the remaining water droplets are accumulated between the baffle 321 and the inner wall of the first through hole 311 due to the gravity, and the remaining water droplets are difficult to pass over the second end of the baffle 321. Therefore, the remaining water droplets are not easy to pass through the water outlet 322. When the water retaining part 320 is in the unfolded state, the water retaining part 320 is stretched open by the cannula 100, so that the water outlet 322 of the water retaining part 320 in the unfolded state is larger than the water outlet 322 of the water retaining part 320 in the retracted state, which can facilitate the water flow through the water outlet 322 and improve the fluidity of the water flow.
[0060] It is understandable that in some other embodiments, when the water retaining portion 320 is in the retracted state, the second ends of the plurality of baffles 321 can be fitted together to form a gap, which can also be understood as a small spacing between two adjacent baffles 321. The gap can be in the shape of a straight line, a herringbone, a cross or a cross, depending on the number of baffles 321. When the water retaining portion 320 is in the retracted state, the baffles 321 can block the residual water droplets from passing through the baffles 321 and flowing out of the first sealing member 300 due to the small gap. When the water retaining portion 320 is in the expanded state, the cannula 100 can open the plurality of baffles 321, thereby expanding the above-mentioned gap to expand the gap into an opening, which can connect the cannula 100 with the channel 210 to ensure that the water flow can flow normally.
[0061] It is understandable that, referring to Figure 3 As shown, in some embodiments, the inner wall of the first through hole 311 includes a first peripheral wall 3111 and a second peripheral wall 3112 connected to each other, the inner diameter of the second peripheral wall 3112 is larger than the inner diameter of the first peripheral wall 3111, and the axis of the first peripheral wall 3111 and the axis of the second peripheral wall 3112 can be coaxially arranged. The water retaining part 320 is connected to the first peripheral wall 3111. When the plug-in connection structure 1000 is in the plug-in state, the cannula 100 is inserted into the first peripheral wall 3111, and the cannula 100 opens the water retaining part 320 toward the second peripheral wall 3112. Since the inner diameter of the second peripheral wall 3112 is larger, there is a certain gap between the water retaining part 320 and the second peripheral wall 3112, which can alleviate the adhesion phenomenon between the water retaining part 320 and the inner wall of the first through hole 311, and ensure that the water retaining part 320 can be normally restored from the expanded state to the retracted state. In some embodiments, the water retaining portion 320 can be connected to the junction of the first peripheral wall 3111 and the second peripheral wall 3112, so that most of the structure of the water retaining portion 320 is located inside the second peripheral wall 3112, thereby reducing the contact area between the water retaining portion 320 and the first peripheral wall 3111 and alleviating the adhesion phenomenon between the water retaining portion 320 and the first peripheral wall 3111.
[0062] It is understandable that, referring to Figure 4 and Figure 8As shown, in some embodiments, the outer wall of the main body 310 is provided with a flange 312 arranged along the circumference of the main body 310, and the flange 312 can be connected to the main body 310 in an integrated structure. The flange 312 abuts against the inner wall of the channel 210. The flange 312 can be understood as an annular structure. The outer diameter of the flange 312 is larger than the outer diameter of the main body 310. The contact area between the flange 312 and the inner wall of the channel 210 is small, which can reduce friction and facilitate the main body 310 to be installed in the channel 210. The flange 312 can also produce a certain deformation. After the main body 310 is installed in the channel 210, the flange 312 is squeezed by the inner wall of the channel 210, thereby clamping the main body 310 to ensure that the flange 312 is tightly fitted with the inner wall of the channel 210 to ensure good sealing performance. In some embodiments, there may be multiple flanges 312 , and the multiple flanges 312 are arranged at intervals along the circumference of the main body 310 . Providing multiple flanges 312 can ensure a stable connection between the main body 310 and the channel 210 .
[0063] It is understandable that during the process of inserting the cannula 100 into the first sealing member 300, the cannula 100 easily brings the first sealing member 300 into the channel 210, making it difficult to remove the first sealing member 300 from the channel 210. Figure 4 and Figure 8 As shown, in some embodiments, part of the structure of the main body 310 is located in the channel 210, and the outer peripheral wall of the main body 310 is provided with a flange 313. The flange 313 and the main body 310 can be connected as an integral structure. The flange 313 is arranged along the circumference of the main body 310. The flange 313 can be understood as an annular structure. The outer diameter of the flange 313 is larger than the outer diameter of the main body 310. The flange 313 is located at the end of the main body 310 away from the connecting piece 200, and the flange 313 is located outside the channel 210. The flange 313 abuts against the outer wall of the connecting piece 200. When the cannula 100 is inserted into the first seal 300, the flange 313 can support the first seal 300 to prevent the cannula 100 from completely bringing the first seal 300 into the channel 210, which can facilitate the subsequent removal of the first seal 300.
