Of course, this is merely a specific example of the water tank 202.

It is understood that the waterway delivery pipes 206/206a are not limited to the specific form in the above examples, and may be provided in various forms as long as they can be connected to the adapter pipe 213 of the adapter 211.

Referring to fig. 6 and 7a, the adapter 211 includes:

a housing 212;

the first end 214 of the adapting pipe 213 is connected to the housing 212, the second end 215 of the adapting pipe 213 extends out of the housing 212, and the second end 215 of the adapting pipe 213 is used for detachably connecting with the waterway delivery pipe 206/206a of the water tank 202.

It is understood that "the first end 214 of the transit tube 213 is connected to the housing 212" means that the first end 214 of the transit tube 213 is at least partially connected to the housing 212, and for example, the first end 214 of the transit tube 213 does not extend out of the housing 212, and the first end 214 of the transit tube 213 partially extends out of the housing 212, which is not particularly limited in this application. In addition, the adapting pipe 213 may be in a straight pipe shape or a non-straight pipe shape, which is not limited in this application, and in a specific example, the first end 214 of the adapting pipe 213 may be in an L shape and may partially protrude outside the housing 212.

It is understood that the "adapting pipe 213" may include only a single water pipe, or may be formed by connecting at least two water pipes, which is not limited in this application as long as it can function as the waterway transmission pipe 206/206a for connecting the external waterway with the water tank 202.

In some embodiments, the second end 215 of the transit tube 213 is configured to mate with the waterway delivery tube 206/206a of the water tank 202.

The embodiment of the application utilizes the switching pipeline 213 of the adapter 211 to be directly plugged with the waterway delivery pipeline 206/206a of the water tank 202, so that the adapter 211 can be separated from the water tank 202 by pulling out the adapter 211 from the water tank 202, and then the water tank 202 can be detached, thereby being beneficial to the quick taking out of the water tank 202.

Moreover, the switching pipeline 213 of the adapter 211 is directly inserted into the waterway delivery pipeline 206/206a of the water tank 202, so that auxiliary tools for dismounting are not needed, the problems of storage and easy loss of the auxiliary tools for dismounting are avoided, and the use of users is facilitated.

Specifically, in this embodiment, the second end 215 of the transfer line 213 is adapted to be inserted into the waterway delivery line 206/206a of the water tank 202. Of course, in other embodiments, the second end 215 of the transit tube 213 may also be used for the insertion of the waterway delivery tube 206/206a, and the application is not limited thereto.

In this embodiment, the transit tube 213 coupled to the housing 212 may include two.

Specifically, one of the adapting pipes 213 may be used to deliver external clean water to the water tank 202, and the other adapting pipe 213 may be used to deliver sewage discharged from the water tank 202 to the outside. Thus, the switching function of automatic water supply and automatic water discharge can be realized by using one adapter 211.

Of course, adapter 211 includes no number of adapter tubes 213 limited to two in the above-described embodiments. Illustratively, adapter 211 may include only one adapter conduit 213. The transit pipe 213 may be used for transporting fresh water or sewage, although it is not excluded that the same transit pipe 213 may be selectively connected to different waterway transport pipes 206/206a for transporting fresh water or sewage. When the base station includes both the waterway transmission pipe 11 for automatic water supply and the waterway transmission pipe 12 for automatic water discharge, different adapter pipes 213 of the adapter 211 may be respectively connected thereto.

Referring to fig. 5, in this embodiment, the housing 212 may have a first limiting structure 216 therein for limiting the adapting pipe 213, and the adapting pipe 213 is inserted into the first limiting structure 216 and is in clearance fit with the first limiting structure 216 in the cross-sectional direction of the adapting pipe 213.

It should be noted that the gap is not a process gap, but a gap reserved during manufacturing, so as to avoid that the adapter pipe 213 cannot be assembled or is difficult to assemble due to process errors, thereby effectively improving the assembly efficiency.

Specifically, the housing 212 may include a housing 217 and a joint 218, the joint 218 being connected to one side of the housing 217. The adapter 218 is disposed over the adapter tube 213, and the first end 214 of the adapter tube 213 partially extends beyond the adapter 218. The other side of the housing 217 remote from the fitting 218 forms a side wall 219, the side wall 219 projecting beyond the first stop 216 in the direction of the fitting 218, the first end 214 of the transfer conduit 213 being partially inserted into the first stop 216. By means of the clearance fit between the adapting pipe 213 and the first limiting structure 216 in the cross-sectional direction of the adapting pipe 213, the assembling of the shell 217 and the adapting pipe 213 is facilitated, and the situation that the adapting pipe 213 and the shell 217 cannot be assembled or are difficult to assemble due to process errors is avoided.

The housing 217 includes a first housing 220 and a second housing 221 detachably connected, and the first housing 220 and the second housing 221 may be connected by a fastener such as a snap connection or a screw.

Further, the first limiting structure 216 may include a plurality of limiting pieces 222 disposed around the adapting pipe 213, wherein the adapting pipe 213 is in clearance fit with the limiting pieces 222 at both sides thereof in the cross-sectional direction of the adapting pipe 213.

The joint 218 may be formed with a through hole 223 formed on the adaptor pipe 213, and the cross-sectional size of the through hole 223 is gradually reduced from a side close to the housing 217 to a side far from the housing 217. The cross-sectional dimension of at least a portion of the outer wall of the transit tube 213 tapers from the first end 214 of the transit tube 213 to the second end 215 of the transit tube 213. The housing 212 and the adapter tube 213 may be formed separately during manufacture and then assembled to form the adapter 211. In the assembly direction of the adapter tube 213 to the housing 212, the second end 215 of the adapter tube 213 may first be inserted into the joint 218 from the end of the through hole 223 with the larger cross-sectional dimension until the tapered outer wall portion of the adapter tube 213 is retained in the through hole 223 and the first end 214 of the adapter tube 213 partially extends beyond the joint 218. Along the assembly direction of the adapting pipe 213 to the housing 212, the size of the cross section at the inlet of the through hole 223 is slightly larger, so that the adapting pipe 213 can be inserted easily, and the size of the outlet is slightly smaller, so that the adapting pipe 213 can be aligned with the joint 218 reliably, and the adapting pipe 213 can be firmly limited at the joint 218.

Referring to fig. 6 and 7b, in this embodiment, a first radial sealing ring 224 may be disposed between the second end 215 of the adapting pipe 213 and the waterway delivery pipes 206/206a, so as to ensure the sealing performance between the adapting pipe 213 and the waterway delivery pipes 206/206a when the adapting pipe 213 is inserted into the waterway delivery pipes 206/206a. In some embodiments, the first radial sealing ring 224 may be sleeved on an outer side wall of the adapter tube 213, and more specifically, an outer annular groove 225 may be provided on the outer side wall of the adapter tube 213, and the first radial sealing ring 224 may be snapped into the outer annular groove 225. In other embodiments, the first radial sealing ring 224 may be disposed on an inner sidewall of the waterway delivery conduit 206/206a, and more particularly, the inner sidewall of the waterway delivery conduit 206/206a may be provided with an inner annular groove into which the first radial sealing ring 224 may snap.

For example, the first radial sealing rings 224 may include two, and two first radial sealing rings 224 may be spaced apart along the axial direction of the waterway delivery conduit 206/206a. Of course, in other embodiments, the number of first radial seal rings 224 may be other.

When the transit pipe 213 is inserted into the transit pipe 206/206a, the radial sealing ring O is compressed between the transit pipe 206/206a and the transit pipe 213, so that sealability between the transit pipe 213 and the transit pipe 206/206a can be ensured.

Referring to fig. 2, fig. 6 and fig. 7a to fig. 7b, in this embodiment, the adapting pipe 213 includes a first water pipe 226 and a second water pipe 227, and the first water pipe 226 and the second water pipe 227 can be sleeved with each other. In other embodiments, the first and

second water pipes

226 and 227 are not limited to being sleeved. The number of water pipes of the connection pipe 213 is not limited as long as the connection between the external water path and the water path delivery pipe 206/206a can be achieved.

As shown in fig. 2, a second radial sealing ring 228 may be further disposed between the first water pipe 226 and the second water pipe 227, and by disposing the second radial sealing ring 228, the sealing performance between the first water pipe 226 and the second water pipe 227 may be improved, and the risk of water flowing to the outside from the gap between the first water pipe 226 and the second water pipe 227 may be reduced.

second water pipes

226 and 227 is not limited to the snap 229 connection. For example, the first water pipe 226 and the second water pipe 227 may be ultrasonically welded together; it is not excluded that the snap 229 connection and the ultrasonic welding are simultaneously performed between the first water pipe 226 and the second water pipe 227.

In addition, a check valve 237 may be disposed between the first and

second water pipes

226 and 227, and the check valve 237 is used to block or open a waterway channel formed by the first and

second water pipes

226 and 227. Further, when the transit pipe 213 is not connected to the corresponding waterway transmission pipe 11, the check valve 237 is in the first state to block the waterway channel, when the transit pipe 213 is connected to the waterway transmission pipe 11, the check valve 237 is in the second state to open the waterway channel, and when the transit pipe 213 is disconnected from the waterway transmission pipe 11, the check valve 237 may restore the first state to block the waterway channel again; in the case where the transit pipe 213 is used to convey fresh water, when the transit pipe 213 is separated from the waterway conveying pipe 11, it is possible to prevent the fresh water from being directly sprayed from the transit pipe 213. Illustratively, the check valve 237 may be a spring-type check valve, and when the adaptor pipe 213 is connected to the waterway delivery pipe 11, the check valve 237 may be pushed to be converted from the first state to the second state, and when the adaptor pipe 213 is disconnected from the waterway delivery pipe 11, the check valve 237 may be automatically reset to the first state.

More specifically, the transit passage 213 may include two, the check valve 237 is disposed in one of the transit passages 213, the check valve 237 includes a spool 238 and an elastic member 239, and the inner wall of the first water pipe 226 is formed with a first step 240; the spool 238 is disposed in the second water pipe 227, and the elastic member 239 abuts between the first land 240 and the spool 238. When the adapting pipe 213 is inserted into the waterway transmission pipe 11, the elastic member 239 is compressed, the check valve 237 is in an open state, and when the adapting pipe 213 is removed from the waterway transmission pipe 11, the elastic member 239 is deformed again, so that the check valve 237 is in a closed state. Specifically, when the switching pipe 213 is inserted into the waterway transmission pipe 11, the valve core 238 is at the first position to block the waterway channel, and the elastic member 239 is in a release state; in a state where the transit pipe 213 is inserted into the waterway transmission pipe 11, the valve core 238 is pushed to a second position to open the waterway passage, and the elastic member 239 is in a compressed state; when the transit pipe 213 is disconnected from the waterway delivery pipe 11, the valve core 238 is reset to the first position by the elastic member 239 when the elastic member 239 is released from the compressed state. Further, in order to reliably push the valve body 238 when the adapter pipe 213 is inserted into the water

channel delivery pipes

206 and 206a, the pushing portion 241 is provided in the corresponding water channel delivery pipe 11.

A first step 240 is formed due to the inner wall of the first water tube 226; the valve core 238 is disposed in the second water pipe 227, and the elastic member 239 abuts between the first step 240 and the valve core 238, so that the corresponding second water pipe 227 does not need to be processed with a step for abutting the elastic member 239, and moreover, since the one-way valve 237 does not need to be installed on the other of the switching pipes 213, no step is naturally processed, thereby facilitating the processing of the second water pipes 227 of the two switching pipes 213 by using the same mold.

Referring to fig. 2, further, a second step 243 is formed at a connection portion of the third pipe portion 234 and the fourth pipe portion 235; the second step 243 is formed with an inner chamfer 244 toward one side of the fourth pipe portion 235; the valve core 238 is sleeved with a sealing ring 245, and when the valve core 238 is in a position which enables the one-way valve 237 to be in a closed state, the sealing ring 245 is abutted against the inner chamfer 244. By the cooperation of the sealing ring 245 and the inner chamfer 244 on the second step 243, a better sealing effect can be achieved. In addition, since the second water pipes 227 of the two adapter conduits 213 form the second step 243 and the inner chamfer 244, it is convenient to machine the second water pipes 227 of the two adapter conduits 213 by using the same set of mold. Specifically, the second step 243 includes a fitting portion 246 protruding into the fourth pipe portion 235, and an inner chamfer 244 is formed on a side of the fitting portion 246 facing the fourth pipe portion 235; in a particular example, the water inlet end of the duckbill valve 242 within the transit tube 213 for transporting sewage is sleeved with a mounting portion 246.

Furthermore, the valve core 238 comprises a main body 247 and a plug 248, wherein the main body 247 is slidably disposed in the third tube 234, and the plug 248 is connected to one end of the main body 247 and is used to abut against the second step 243; the seal 245 is located in the body portion 247 of the spool 238 adjacent the plug portion 248. By the technical means, the valve core 238 can be moved reliably, and the cut-off effect of the valve core 238 can be ensured.

In some embodiments, one of the two transfer conduits 213, which is provided with the one-way valve 237, is used for conveying fresh water, and the other transfer conduit 213 is used for conveying sewage. Illustratively, a duckbill valve 242 may be disposed in the adapting pipe 213 for delivering sewage, when the adapting pipe 213 is connected to the corresponding waterway delivery pipe 206/206a, the duckbill valve 242 is in a closed or slightly opened state under no or low water pressure, which can prevent the sewage from flowing out, and when the water pressure exceeds a certain level, the duckbill valve 242 may be opened under the water pressure to allow the sewage to flow out.

The number of the duckbill valves 242 may be at least two, and in one embodiment, as shown in fig. 6 and 7b, an installation auxiliary sleeve 242a for installing the duckbill valves 242 may be provided in the transit tube 213, wherein one duckbill valve 242 (e.g., the duckbill valve 242 on the left side in fig. 6 and 7 b) may extend into the inside of the installation auxiliary sleeve 242a, and the other duckbill valve 242 may be sleeved outside of the installation auxiliary sleeve 242 a.

In some embodiments, the second water tubes 227 in the two adapter pipes 213 may have the same structural shape. Since the step in one of the adapter conduits 213, against which the elastic member 239 of the check valve 237 abuts, is provided in the first water pipe 226, and the other adapter conduit 213 does not need to be provided with the check valve 237, it is advantageous to process the second water pipes 227 of the two adapter conduits 213 to have the same structural shape.

Referring to fig. 7a to 7b, more specifically, the first water pipe 226 is L-shaped, and includes a horizontal pipe portion 249 and a vertical pipe portion 250, wherein the horizontal pipe portion 249 is connected to the second water pipe 227, the vertical pipe portion 250 is used for connecting an external waterway, and the vertical pipe portion 250 may partially protrude outside the housing 212. Of course, this is only a specific example of the first water pipe 226, and the first water pipe 226 is not limited thereto.

Referring to fig. 2 and 3, in this embodiment, the water tank 202 is provided with a second limiting structure 251 for limiting the waterway delivery pipe 206/206a, and the second limiting structure 251 is in clearance fit with the waterway delivery pipe 206/206a in the cross-sectional direction of the waterway delivery pipe 206/206a. The waterway delivery tube 206/206a may be connected to the water tank 202 through a hose 252 (e.g., a silicone hose), so that the waterway delivery tube 206/206a may have a certain swing space due to the presence of the hose 252. And the second limit structure 251 is in clearance fit with the waterway delivery pipe 206/206a, so that when the adapter pipe 213 is plugged with the waterway delivery pipe 206/206a, the waterway delivery pipe 206/206a can swing transversely within a small range in the second limit structure 251, thereby facilitating the rapid assembly of the adapter pipe 213 to the waterway delivery pipe 206/206a.

It should be noted that the gap is not a process gap, but a gap reserved in manufacturing, in order to avoid that the adapter pipe 213 cannot be assembled due to process errors.

Specifically, the second limiting structure may include an opening 253 formed in the wall of the water tank 202, the opening 253 corresponding to the waterway transmission pipe 206/206a located in the water tank 202, the transit pipe 213 is inserted into the waterway transmission pipe 206/206a through the opening 253, and the transit pipe 213 is clearance-fitted with the opening 253 in the cross-sectional direction thereof.

In a specific example, as shown in fig. 3, the position where the socket 205 on the base station housing 203 communicates with the accommodation space 204 forms a socket 254, and the socket 254 corresponds to the waterway delivery pipe 206/206a located in the water tank 202. The transit pipe 213 is inserted into the waterway delivery pipe 206/206a through the insertion hole 254, and the transit pipe 213 is clearance-fitted into the insertion hole 254 in a cross-sectional direction thereof.

Referring to fig. 2 and 7a, in this embodiment, a pressing buckle structure 255 is disposed on a side portion of the housing 212, and the pressing buckle structure 255 includes a pressing piece 256 and a buckle 257 connected to the pressing piece 256; the latch 257 is configured to be latched to the base station main body 201 when the adapter 211 is plugged to the base station main body 201, and to be retracted so that the adapter 211 can be pulled out from the base station main body 201 when the pressing piece 256 is pressed. It should be noted that, for example, as shown in fig. 4c, the latch 257 is retracted, which means that the latch 257 moves in a direction close to the adapter tube 213 (in the embodiment of the present application, this direction may be referred to as a retraction direction) to disengage the base station housing 203, so that the adapter 211 can be pulled out from the base station main body 201. By pressing the clamping connection between the clamping structure 255 and the base station main body 201, the reliable assembly of the adapter 211 and the base station main body 201 is facilitated. It should be noted that the pressing member 256 and the snap member 257 may be an integral structure.

In a specific example, two sides of one end of the socket 205 of the base station housing 203, which is away from the accommodating space 204, are provided with a clamping groove 258, the housing 212 of the adapter 211 is partially inserted into the socket 205, the clamping piece 257 is clamped into the clamping groove 258, and the adapting pipe 213 passes through the socket 205 and then is plugged into the waterway delivery pipe 206/206a of the water tank 202.

As shown in fig. 4c, in some embodiments, the latch 257 includes a first protrusion 2571 protruding in a direction away from an insertion direction of the adapter 211 into the base station main body 201, and a blocking portion 2031 for blocking movement of the latch 257 and the first protrusion 2571 in the retraction direction is disposed on a side surface of the base station main body 201 (specifically, the base station housing 203) facing the latch 257. The base station provided by the embodiment of the application can automatically supply water and automatically discharge water, in the automatic water supply and automatic water discharge processes, water pressure exists in the adapter pipe 213, and under the action of the water pressure, the snap member 257 of the adapter 211 tends to move relative to the base station housing 203 (as shown in fig. 4c, the direction of the movement trend of the snap member 257 is substantially the same as the direction of the water pressure in the drawing). In this way, the first protrusion 2571 of the latch 257 moves to a position where it is retained by the blocking portion 2031, and in this state, even if the user presses the pressing piece 256, the adapter 211 cannot be removed from the base station body 201. Therefore, when the base station normally goes up and down with water, the user cannot pull out the adapter 211 from the base station main body 201, and the risk that the adapter 211 is pulled out or falls out from the base station main body 201 to cause liquid leakage in the normal water-up and down process of the base station is reliably avoided.

As to the specific configuration of the blocking portion 2031, in a specific example, the blocking portion 2031 may be a second protrusion formed on the base station housing 203. In another example, the surface of the base station housing 203 facing the snap member 257 is provided with a recess, a groove side wall of which forms the above-mentioned blocking portion 2031. The design can be carried out by those skilled in the art according to specific needs, and the embodiments of the present application are not particularly limited.

Various embodiments or examples and features of various embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.

The above description is only a part of the present application or a preferred embodiment, and neither the text nor the drawings should be construed as limiting the scope of the present application, and all the equivalent structural changes made by the contents of the present specification and the drawings or the related technical fields directly/indirectly by the concepts of the present application are included in the scope of the present application.
