Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a liquid supply device according to an embodiment of the application. The embodiment of the present application provides a liquid supply apparatus 100, where the liquid supply apparatus 100 may include at least one of a water dispenser, an atomizer, and a humidifier, and the embodiment of the present application is not limited thereto.

The liquid supply device 100 may be applied to a refrigerator, may be applied to other devices, or may be independently used, which is not limited in the embodiment of the present application.

With continued reference to fig. 2 to 4, fig. 2 is a front view of the liquid supply apparatus shown in fig. 1, fig. 3 is a cross-sectional view of the liquid supply apparatus shown in fig. 2 taken along the direction A-A, and fig. 4 is a partially enlarged view at X in fig. 3. The liquid supply apparatus 100 may further include a mounting base 12, a first sealing member 14, a liquid container 13, and a second sealing member 15. The liquid container 13 has a first accommodation chamber 1311 and a first water outlet 1312 communicating with the first accommodation chamber 1311. The first sealing member 14 is provided to the liquid container 13, and the first sealing member 14 is used to close or open the first water outlet 1312. The mounting base 12 is detachably connected to the liquid container 13. The mounting base 12 is provided with a liquid outlet channel 121, and the liquid outlet channel 121 is communicated with a first water outlet 1312. The second sealing member 15 is at least partially disposed in the liquid outlet channel 121. The second sealing member is used for sealing the gap between the liquid outlet channel 121 and the first water outlet 1312.

In the embodiment of the present application, on the one hand, when the liquid container 13 is detached, the first water outlet 1312 of the liquid container 13 may be sealed by the first sealing member 14, so that the liquid in the first accommodating chamber 1311 is prevented from leaking out after the liquid container 13 is removed. On the other hand, after the liquid container 13 is mounted, the first water outlet 1312 may be opened by the first sealing member 14, and a gap between the liquid outlet passage 121 and the first water outlet 1312 may be sealed by the second sealing member 15 to prevent leakage of liquid during the supply of liquid from the liquid container 13. Therefore, the liquid supply device 100 according to the embodiment of the application is not easy to leak on the basis of being detachable, so that the user is not required to clean the leaked liquid, and the liquid supply device 100 according to the embodiment of the application has the advantages of easy maintenance and disassembly.

In some embodiments, the second sealing member 15 may be snapped into at least two different positions of the mounting base 12. It will be appreciated that since the liquid container 13 is removable, the second sealing member 15 is easily displaced or removed during repeated removal of the liquid container 13. In the embodiment of the present application, the second sealing member 15 is clamped to at least two different positions of the mounting base 12, and the second sealing member 15 is clamped to the mounting base 12 more firmly, so as to improve the reliability of the seal between the mounting base 12 and the liquid container 13.

In some embodiments, the mounting base 12 may include a first annular portion 122, the first annular portion 122 being disposed around the first water outlet 1312 to enclose at least a portion of the liquid outlet passage 121, the second sealing member 15 being mounted to the first annular portion 122.

With continued reference to fig. 4 and 5, fig. 5 is a schematic structural view of the second sealing member shown in fig. 4. The second sealing member 15 may include a first ring-shaped body 151. The first ring body 151 is fixedly disposed inside the first ring portion 122. The first annular body 151 is compressively disposed between the first annular portion 122 and the liquid container 13 to seal the first annular portion 122 and the first water outlet 1312.

For example, the liquid container 13 may include a third annular portion 1313. The third annular portion 1313 is disposed around the first outlet 1312 and at least partially inboard of the first annular portion 122. At this time, at least one third flange 152 is protruded on the inner side of the first ring body 151. The third flange 152 is disposed obliquely in a direction away from the opening of the first annular portion 122, and the third flange 152 abuts against the third annular portion 1313 to seal a gap between the first annular portion 122 and the third annular portion 1313.

Thus, when the liquid container 13 is mounted to the mounting base 12, the third annular portion 1313 is inserted into the first annular portion 122, and the first annular body 151 is compressed between the inner wall of the first annular portion 122 and the outer wall of the third annular portion 1313 to achieve sealing. Meanwhile, since the third flange 152 may be simply understood as being inclined inwardly, the third annular portion 1313 may be more conveniently inserted into the first annular portion 122 with less effort.

It will be appreciated that the number of third flanges 152 may be one or more, such as two, three, four, depending on the actual sealing requirements, and the embodiment of the present application is not limited thereto.

In some embodiments, the second sealing member 15 may further include a first flange 153. The first flange 153 is protruding from a side of the first annular body 151 facing away from the opening of the first annular portion 122. The first flange 153 is clamped to the inner wall of the first annular portion 122. Thereby realizing the clamping and fixing of the second sealing component 15 and the mounting base 12.

It will also be appreciated that during actual removal of the liquid container 13, it will be appreciated that the third annular portion 1313 of the liquid container 13 needs to be pulled out of the first annular body 151. At this time, by clamping the first flange 153 to the inner wall of the first annular portion 122, there is a possibility that the second sealing member 15 is pulled out following the third annular portion 1313 during the disassembly, so that the seal between the mounting base 12 and the liquid container 13 is more reliable.

In some embodiments, the outer wall of the first annular portion 122 is convex with a circumferential ring of the second annular portion 123. The second sealing member 15 further includes a second flange 154. The second flange 154 is convexly arranged on one side of the first annular main body 151, which is close to the opening of the first annular part 122, and the second annular part 123 is clamped in the second flange 154, so that the clamping and fixing of the second sealing part 15 and the mounting base 12 are realized.

It will also be appreciated that during installation and removal of the liquid container 13, it will be appreciated that the third annular portion 1313 of the liquid container 13 needs to be inserted into the first annular body 151. At this time, by clamping the second flange 154 to the outer wall of the first annular portion 122, the second sealing member 15 is pressed into the first annular portion 122 too much in the installation process, so that the liquid container 13 cannot be installed normally, or the liquid container 13 is installed erroneously to affect the sealing effect, so that the user experience of the embodiment of the application can be reduced.

For example, the second flange 154 can include a first section, a second section, and a third section connected in series. The second section is spaced from the outer wall of the first annular body 151, and the first section is connected to the second section and the first annular body 151, respectively. The third section is provided at a side of the second section facing the outer wall of the first ring body 151. Further, the outer wall, the first section, the second section and the third section of the first annular body 151 form an L-shaped slot, and the second annular portion 123 is embedded in the L-shaped slot.

With continued reference to fig. 4 and 6, fig. 6 is a schematic structural view of the abutment shown in fig. 4. In some embodiments, the mounting base 12 is further provided with an abutment 16, the abutment 16 comprising a mounting portion 161 and a push rod 162. The mounting portion 161 is fixedly provided on the inner wall of the liquid outlet channel 121. The push rod 162 is connected to the mounting portion 161, and the push rod 162 is used to abut against the first sealing member 14 to open the first water outlet 1312.

Thus, after the liquid container 13 is inserted into the mounting base 12 to be mounted, the first water outlet 1312 of the liquid container 13 can be automatically pushed up by the push rod 162, so that the liquid in the liquid container 13 can be discharged through the first water outlet 1312, the liquid outlet channel 121 and the valve body assembly 11. It can be appreciated that the liquid supply apparatus 100 according to the embodiment of the present application has the advantage of more convenient use because the first water outlet 1312 does not need to be opened manually after the liquid container 13 is inserted into the mounting base 12.

In some embodiments, the outer peripheral side of the mounting portion 161 is provided with a step 1611, and a first engagement groove is formed around the inner wall of the liquid outlet channel 121, and the second sealing member 15 is engaged with the first engagement groove.

Specifically, the mounting portion 161 may be provided on the inner wall of the first annular portion 122, so that the first flange 153 of the second sealing member 15 is engaged with the inner wall of the first annular portion 122 by the mounting portion 161, or the second sealing member 15 is engaged with the first engagement groove located on the inner wall of the first annular portion 122.

In addition, the second sealing component 15 and the mounting portion 161 can be mutually limited, so that the abutting piece 16 and the second sealing component 15 are more stable and reliable in the process of disassembly and assembly, and the experience of a user is improved.

In some embodiments, the mounting portion 161 includes a second annular body 1612 and a first connecting rib 1613. The second annular body 1612 abuts against an inner wall of the liquid outlet channel 121 such as an inner wall of the first annular portion 122. One end of the first connecting rib 1613 is connected with the second annular body 1612, and the other end of the first connecting rib 1613 is connected with the ejector rod 162. So that a channel for liquid to flow through is formed between the two connecting ribs.

Wherein the number of the push rods 162 may be at least one.

For example, the number of the jack 162 may be plural, such as two, three, four, or even five. It will be appreciated that the volume of the first sealing member 14 is fixed, and that the more the ejector rods 162 are used to abut against the first sealing member 14 means that the volume of each ejector rod 162 is smaller, and that the more space is provided between the whole body formed by the plurality of ejector rods 162 for the liquid to flow therethrough, so that the liquid supply efficiency can be improved.

With continued reference to fig. 4 and 7, fig. 7 is a schematic structural view of the first sealing member shown in fig. 4. In some embodiments, the first sealing member 14 may include a second piston 141, a second support rod 142, and a second elastic member 143. The second piston 141 is at least partially disposed within the first receiving chamber 1311. The second support rod 142 is disposed through the first water outlet 1312, and the second support rod 142 is fixedly connected with the second piston 141. The second elastic member 143 is disposed outside the first accommodating cavity 1311, and is used for pushing the second supporting rod 142 to move outside the first accommodating cavity 1311, so that the second piston 141 closes the first water outlet 1312.

Therefore, after the liquid container 13 is removed from the mounting base 12, the second support rod 142 and the second piston 141 can automatically close the first water outlet 1312 of the liquid container 13 under the driving of the second elastic member 143, so as to avoid liquid leakage in the process of removing the liquid container 13.

Continuing to provide the abutment member 16 in conjunction with the above-mentioned mounting base 12, the push rod 162 may abut against the second support rod 142 after the liquid container 13 is mounted on the mounting base 12, so that the second support rod 142 moves toward the inside of the first receiving cavity 1311, thereby compressing the second elastic member 143, and the second piston 141 opens the first water outlet 1312.

Continuing to join the liquid container 13 further comprises a third annular portion 1313, the third annular portion 1313 being disposed around the first water outlet 1312, for example, the first sealing member 14 may further comprise a third annular body 144 and a second connecting rib 145. Third annular body 144 is slidably mounted to an inner wall of third annular portion 1313. One end of the second connecting rib 145 is connected with the third annular main body 144, the other end of the second connecting rib 145 is connected with the second supporting rod 142, and the second elastic piece 143 is abutted between the outer wall of the first accommodating cavity 1311 and the second connecting rib 145. Thereby achieving an automatic sealing of the first sealing member 14 to the first water outlet 1312.

In some embodiments, the outer surface of the second piston 141 may include a first chamfer 1411. The first inclined surface 1411 is located on a side of the second piston 141 facing the first water outlet 1312. Wherein, along the direction of the first water outlet 1312 towards the outside of the first accommodating cavity 1311, the first inclined surface 1411 is inclined towards the direction close to the axial line of the first water outlet 1312. Further, when the second support rod 142 moves toward the outside of the first receiving cavity 1311, the second piston 141 may be wedge-fastened at the first water outlet 1312 by the first inclined surface 1411, so that the sealing of the second piston 141 is more stable and reliable.

In some embodiments, the outer surface of the second piston 141 may include a second chamfer 1412. The second sloped surface 1412 is located on a side of the piston facing away from the first water outlet 1312. The second inclined surface 1412 is inclined in a direction approaching to the axis of the first water outlet 1312 along the direction of the first water outlet 1312 facing the inside of the first accommodating cavity 1311. Further, the liquid in the liquid container 13 can more reasonably apply the water pressure to the second piston 141 by the second slope 1412, so that the second piston 141 can more firmly seal the first water outlet 1312.

Specifically, the outer surface of the second piston 141 may be provided with only the first inclined surface 1411, only the second inclined surface 1412, or both the first inclined surface 1411 and the second inclined surface 1412, which is not limited in the embodiment of the present application.

With continued reference to fig. 8, fig. 8 is an exploded view of the liquid supply apparatus shown in fig. 1. In some embodiments, the mounting base 12 may include two storage boxes 124 spaced apart along the first direction. The liquid container 13 is clamped between the two storage boxes 124.

It will be appreciated that embodiments of the present application may also be used to multiplex two cartridges 124 on the mounting base 12 to the clamping fluid container 13, thereby making the structure on the mounting base 12 more compact.

In some embodiments, the outer wall of the storage box 124 may be provided with a first stop rib 1241, so that the liquid container 13 is stopped by the first stop rib 1241.

In some embodiments, the mounting base 12 further includes a support portion 125 connected between the two storage boxes 124, the support portion 125 being provided with a first limit protrusion 1251.

With continued reference to fig. 9, fig. 9 is an exploded view of the liquid container in fig. 8. The liquid container 13 further includes a base 1314 and a second stop rib 1315, where the base 1314 and the second stop rib 1315 are disposed on the same side of the outer wall of the first receiving chamber 1311.

Alternatively, the third annular portion 1313 is also located at the bottom of the liquid container 13. And, the height of the third ring-shaped portion 1313 protruding with respect to the outer wall of the first receiving chamber 1311 is smaller than the height of the lower base 1314 protruding with respect to the outer wall of the first receiving chamber 1311. So that the liquid container 13 can be smoothly placed on a supporting plane such as a table surface by the lower base 1314 after the liquid container 13 is removed so that the liquid container 13 can be used alone.

In some embodiments, the liquid container 13 further includes a third card slot 1316.

With continued reference to fig. 10, fig. 10 is a schematic diagram illustrating a structure of a valve body assembly in the liquid supply apparatus of fig. 3. In some embodiments, the liquid supply apparatus 100 further comprises a valve body assembly 11. The valve body assembly 11 may include a first pipe 111, a second pipe 112, a third pipe 113, and a spool 114.

The first tube 111 is provided to the mounting base 12 and connected to the liquid outlet passage 121. The second pipe 112 is spaced apart from the first pipe 111. The third pipe body 113 is made of deformable material, one end of the third pipe body 113 is connected with the first pipe body 111, and the other end of the third pipe body 113 is connected with the second pipe body 112, so that the first pipe body 111, the third pipe body 113 and the second pipe body 112 are sequentially communicated. The poppet 114 is at least partially disposed within the second body 112. Wherein the second tube 112 is movable in a direction approaching or separating from the first tube 111 to deform the second tube 112 and to open or close the valve body 114 to the first tube 111.

Then, since the first tube 111 and the second tube 112 are connected through the deformable second tube 112, a nested design is not required between the first tube 111 and the second tube 112, or the second tube 112 is not required to be sleeved on the outer peripheral side of the first tube 111 and form sliding connection, so that residual liquid in a long and narrow gap formed between the outer side wall of the first tube 111 and the inner wall of the second tube 112 can be avoided, and further the liquid which flows through the valve body assembly 11 later is prevented from being smelly easily and polluting, thereby improving the experience of users.

The first tube 111 may be integrally formed with the mounting base 12. The first tube 111 and the mounting base 12 may also be formed separately, such as the first tube 111 and the mounting base 12 may be detachably connected, which is not limited in the embodiment of the present application.

It is understood that the first tube 111, the second tube 112 and the third tube 113 may be integrally formed. The first tube 111, the second tube 112, and the third tube 113 may be formed separately; for example, at least one of the first tube 111 and the second tube 112 is connected and fixed with the third tube 113 in a non-detachable way by welding, fusing or the like; or, at least one of the first pipe body 111 and the second pipe body 112 is detachably connected and fixed with the third pipe body 113 through a third clamping groove connection, a clamp locking, a threaded connection and the like, which is not limited in the embodiment of the present application.

In the following, the technical solution of the embodiment of the present application is exemplified by detachable connection of at least one of the first tube 111 and the second tube 112 to the third tube 113.

With continued reference to fig. 11, fig. 11 is a schematic view of a first tube of the valve assembly shown in fig. 10. In some embodiments, a first clamping groove 1111 is formed at an end of the first tube 111 near the third tube 113. One end of the third pipe body 113 is clamped in the first clamping groove 1111, so that detachable connection between the first pipe body 111 and the third pipe body 113 is achieved.

It can be appreciated that, because the first tube 111 and the third tube 113 are detachably connected, the first tube 111 and the third tube 113 can be detached after a period of use, so that the inner walls of the first tube 111, the second tube 112 and the third tube 113 can be conveniently cleaned, and scale and the like on the inner walls of the first tube 111, the second tube 112 and the third tube 113 can be avoided from affecting the use experience of users. In addition, since the first pipe body 111 and the third pipe body 113 are detachably connected, after the components such as the valve core 114, the first pipe body 111, the second pipe body 112, the third pipe body 113 and the like are damaged, the disassembly and the replacement can be more conveniently performed.

In some embodiments, the first card slot 1111 is an annular slot. The first clamping groove 1111 is circumferentially arranged on the outer side wall of the first pipe body 111. The third tube 113 is made of elastic material, and the third tube 113 is clamped into the first clamping groove 1111 near the whole circumference of one side edge of the first tube 111 to form a seal.

Then, based on the elasticity of the third pipe body 113, the third pipe body 113 can realize the relative movement between the first pipe body 111 and the second pipe body 112 through elastic expansion and contraction, and can realize the sealing of the joint of the first pipe body 111 and the third pipe body 113, so that the whole structure of the valve body assembly is simpler, and the manufacturing cost and the disassembly and assembly difficulty of the valve body are reduced.

Referring to fig. 11 and 12, fig. 12 is a schematic structural view of a third tube of the valve body assembly shown in fig. 10. Specifically, two annular first protruding portions may be formed at one end of the first pipe body 111 near the third pipe body 113, and a first clamping groove 1111 may be formed between the two first protruding portions and an outer side wall of the first pipe body 111. Correspondingly, one end of the third pipe body 113, which is close to the first pipe body 111, is provided with a first folded edge 1131 protruding towards the axial line direction of the first pipe body 111, and the first folded edge 1131 is clamped in the first clamping groove 1111, so that clamping and fixing are achieved.

In some embodiments, the valve body assembly 11 may further include a first fastener. The first fastening member is sleeved at one end of the third pipe body 113 close to the first pipe body 111, so as to fasten the third pipe body 113 to the outer wall of the first pipe body 111 in a pressing manner, thereby improving the connection stability of the first pipe body 111 and the third pipe body 113 and improving the sealing effect between the first pipe body 111 and the third pipe body 113.

For example, the first fastener may be a clip, a folding strap, a binder, or the like, to which embodiments of the present application are not limited.

With continued reference to fig. 13, fig. 13 is a schematic diagram of a second tube and a valve core of the valve body assembly shown in fig. 10. In some embodiments, a second clamping groove 1121 is formed at an end of the second tube 112 near the third tube 113. One end of the third pipe body 113 is clamped in the second clamping groove 1121, so that detachable connection between the second pipe body 112 and the third pipe body 113 is realized.

It can be appreciated that, because the second pipe 112 and the third pipe 113 are detachably connected, the second pipe 112 and the third pipe 113 can be detached after a certain period of use, so that the inner walls of the first pipe 111, the second pipe 112 and the third pipe 113 are cleaned, and scale and the like on the inner walls of the first pipe 111, the second pipe 112 and the third pipe 113 are avoided from affecting the use of users. In addition, since the first pipe body 111 and the third pipe body 113 are detachably connected, after the components such as the valve core 114, the first pipe body 111, the second pipe body 112 and the third pipe body 113 are damaged, the disassembly and the replacement can be more conveniently performed.

In some embodiments, the second card slot 1121 is an annular slot. The second clamping groove 1121 is disposed around the outer sidewall of the second tube 112. The third tube 113 is made of elastic material, and the whole circumference of the end edge of the third tube 113, which is close to the second tube 112, is clamped into the second clamping groove 1121 to form a seal.

Then, based on the elasticity of the third pipe body 113, the third pipe body 113 can realize the relative movement between the first pipe body 111 and the second pipe body 112 through elastic expansion and contraction, and can realize the sealing of the joint of the second pipe body 112 and the third pipe body 113, so that the whole structure of the valve body is simpler, and the manufacturing cost and the disassembly difficulty of the valve body are reduced.

Specifically, two annular second protruding portions may be formed at one end of the second pipe body 112 near the third pipe body 113, and a second clamping groove 1121 may be formed between the two second protruding portions and an outer side wall of the second pipe body 112. Correspondingly, one end of the third pipe body 113, which is close to the second pipe body 112, is provided with a second flange 1132 protruding towards the axial line direction of the second pipe body 112, and the second flange 1132 is clamped in the second clamping groove 1121, so that clamping and fixing are realized.

In some embodiments, the valve body assembly 11 may also include a second fastener. The second fastening member is sleeved at one end of the third pipe body 113 close to the second pipe body 112, so as to fasten the third pipe body 113 to the outer wall of the second pipe body 112 in a pressing manner, thereby improving the connection stability of the second pipe body 112 and the third pipe body 113 and improving the sealing effect between the second pipe body 112 and the third pipe body 113.

For example, the second fastener may be a clip, a folding strap, a binder, or the like, to which embodiments of the present application are not limited.

It will also be appreciated that a chamfer may be provided between the inner wall and the side end of the second tube 112 facing the first tube 111 to reduce the accumulation of water on the side end of the second tube 112 facing the first tube 111.

The above are some examples of the detachable connection structure of the third tube 113 in the embodiment of the present application. It should be understood that, in actual use, only the third pipe body 113 may be detachably connected to the first pipe body 111, only the second pipe body 112 and the third pipe body 113, or both the first pipe body 111 and the second pipe body 112 may be detachably connected to the third pipe body 113, which is not limited in this embodiment of the present application.

Next, some other structure of the third pipe 113 will be described.

In some embodiments, the third tube 113 may be made of rubber or silica gel, so that the third tube 113 has good elasticity or deformability, and may also have a good sealing effect. Of course, in some other embodiments, the third tube 113 may be made of other types of elastic materials, which is not limited in this embodiment of the present application.

In some embodiments, at least a portion of the region of the third tube 113 in the axial direction is convex in a direction away from the axis of the third tube 113. So that the third tube 113 can be pushed to start compression deformation from the convex portion by a smaller force, so that the second tube 112 can be conveniently driven to move relative to the first tube 111 in a labor-saving manner, and the valve body can be opened or closed.

In some embodiments, at least a portion of the region of the third tube 113 in the axial direction is concave toward a direction closer to the axis of the third tube 113. Therefore, the third pipe body 113 can be pushed to be compressively deformed by a smaller force, so that the second pipe body 112 can be conveniently driven to move relative to the first pipe body 111 in a labor-saving manner, and the valve body can be opened or closed.

Specifically, the third tube 113 may have only at least a partial region in the axial direction protruding in a direction away from the axis of the third tube 113, the third tube 113 may have only at least a partial region in the axial direction recessed in a direction closer to the axis of the third tube 113, and the third tube 113 may have a partial region in the axial direction recessed in a direction closer to the axis of the third tube 113, and a partial region in the axial direction recessed in a direction closer to the axis of the third tube 113.

For example, in some embodiments, the portion of the third tube 113 between the first tube 111 and the second tube 112 is convex only in a direction away from the axis of the third tube 113.

Further, on the one hand, the whole third pipe body 113 is deformed outwards in the process of being compressed, so that the third pipe body 113 is prevented from being deformed inwards in the process of being compressed to be closed by the third pipe body 113 or interfering with the valve core 114 caused by the inner wall of the third pipe body 113. On the other hand, the side wall of the third pipe body 113 has only one convex structure, so that the excessive concave-convex structure of the third pipe body 113 can be avoided, and the strength and reliability of the third pipe body 113 are low, so that the reliability of the whole valve body assembly 11 is improved.

The third pipe 113 in the embodiment of the present application is illustrated above, and the valve core 114 in the embodiment of the present application is further illustrated and described below.

For example, the poppet 114 may include a first support rod 1141 and a first piston 1142. The first support rod 1141 is at least partially disposed in the second tube 112. The first piston 1142 is mounted and secured to the first support rod 1141. The second pipe 112 can move towards the direction approaching the first pipe 111, so as to drive the first support rod 1141 to move, thereby driving the first piston 1142 to open the first pipe 111.

In some embodiments, to allow the first piston 1142 to more accurately open or close the first tube 111. At least one of the inner wall of the first pipe body 111 and the inner wall of the second pipe body 112 is slidably fitted with the first support rod 1141. So that the sliding track of the first support rod 1141 is more accurate and reliable.

It will be further appreciated that, since the third tube 113 connecting the first tube 111 and the second tube 112 is made of a deformable material, the first support rod 1141 may make the connection between the first tube 111 and the second tube 112 more reliable when the first tube 111 and the second tube 112 are simultaneously slidably connected to the first support rod 1141. For example, after the first pipe body 111 is fixed, the second pipe body 112 will not sag due to deformation of the third pipe body 113, so that coaxiality of the first pipe body 111 and the second pipe body 112 is well ensured.

Illustratively, the inner wall of the first tube 111 is provided with a first sliding groove 1112, and the outer peripheral side of the first supporting rod 1141 is provided with a sliding portion 11411, and the sliding portion 11411 is slidably engaged with the first sliding groove 1112.

Specifically, the first sliding groove 1112 and the sliding portion 11411 may each be disposed along an axial direction of the first tube 111.

In some embodiments, the inner wall of the second pipe body 112 is provided with a second chute 1122, and the outer peripheral side of the first support rod 1141 is provided with a sliding portion 11411, and the sliding portion 11411 is slidably engaged with the second chute 1122.

Specifically, the second chute 1122 and the sliding portion 11411 may each be disposed along an axial direction of the first tube 111.

It is further understood that only the inner wall of the first tube 111 may be provided with the first sliding groove 1112, only the inner wall of the second tube 112 may be provided with the second sliding groove 1122, or the inner wall of the first tube 111 may be provided with the first sliding groove 1112 and the inner wall of the second tube 112 may be provided with the second sliding groove 1122.

That is, the sliding portion 11411 may be partially slidably mounted on the first sliding groove 1112 and partially slidably mounted on the second sliding groove 1122.

At this time, the first support bar may be simultaneously penetrated through the first, second and third pipes 111, 112 and 113.

On the other hand, since the third pipe 113 is made of deformable material, the sliding portion 11411 is slidably mounted on the first sliding groove 1112 and the second sliding groove 1122, so that one end of the third pipe 113 is prevented from being twisted relative to the other end, and thus the operational reliability of the valve body assembly 11 can be ensured.

On the other hand, in the assembling process, the sliding portion 11411 is slidably mounted in the first sliding groove 1112 and the second sliding groove 1122, so as to have a good foolproof effect on the second pipe 112, so as to prevent an error in the angle of the second pipe 112 along the circumferential direction thereof, thereby ensuring that the form and position tolerance in the assembling process of the valve body assembly 11 is more controllable.

For example, the outlet of the end of the second tube 112 remote from the third tube 113 may be downward for the user to receive water. Then, by slidably mounting the sliding portion 11411 to the first sliding groove 1112 and the second sliding groove 1122, respectively, it is avoided that the outlet of the second pipe 112 is inclined downward or in other directions after completion.

For example, in the actual assembly process, the first support rod 1141 may be first mounted to the first pipe body 111; then, the third pipe body 113 and the second pipe body 112 are sequentially sleeved on the first support rod 1141, so that the outlet of the second pipe body 112 is vertically downward; then, the second pipe 112 is respectively clamped to the first pipe 111 and the second pipe 112, so as to complete the assembly of the valve body assembly 11.

In some embodiments, the inner wall of the first tube 111 is provided with a circumferential third protrusion 1113. The first piston 1142 is at least partially located on a side of the third lobe 1113 remote from the slide 11411.

The valve element 114 further includes a first elastic member 1143, where the first elastic member 1143 abuts between the sliding portion 11411 and the third protruding portion 1113, so as to push the first piston 1142 to abut against the third protruding portion 1113, thereby closing the first tube 111.

Specifically, the first elastic member 1143 may be a coil compression spring, or may be another elastic member, which is not limited in this embodiment of the present application.

Then, during actual operation, the second pipe 112 is driven by other force to approach the first pipe 111, the second pipe 112 pushes the first support rod 1141 to move during the approach of the second pipe 111, so that the first piston 1142 is separated from the third boss 1113, and the first elastic member 1143 and the third pipe 113 are compressed, thereby opening the first pipe 111. After the acting force is removed, the first elastic member 1143 is restored, the third tube 113 is relaxed, and the first support rod 1141 is pushed to return, so that the first piston 1142 is abutted against the third boss 1113 again, and the second tube 112 is far away from the first tube 111, so that the first tube 111 is closed again.

It should be further appreciated that, in some other embodiments, the first support rod 1141 may be clamped to the inner wall of the second pipe 112, or the first support rod 1141 is integrally formed to the inner wall of the second pipe 112, which is not limited in the embodiment of the present application.

For example, referring to fig. 15 and 16, fig. 15 is a schematic view of a structure of a door of the refrigerator shown in fig. 14, and fig. 16 is a sectional view of the door of fig. 15 taken along the direction B-B. The outside of the cabinet door 300 may be provided with a water taking groove 31. The mounting base 12 is provided inside the door 300. The mounting base 12 and the valve body assembly 11 are disposed through the box door 300, so that the outlet of the second pipe 112 is located in the water intake groove 31. So that the user can directly take water without opening the door.

With continued reference to fig. 17, fig. 17 is a schematic diagram illustrating the cooperation between the compression bar and the valve assembly in the refrigerator shown in fig. 14. The liquid supply 100 may further include a pressing lever 17. The compression bar 17 is at least partially located within the water extraction channel 31. The pressing lever 17 is rotatably connected to the door 300 for pushing the second tube 112 to move in a direction approaching the first tube 111.

For example, an outer wall of an end of the second tube 112 remote from the first tube 111 is provided with a pushing portion 1123. The middle part of the pressing rod 17 abuts against one side of the pushing part 1123 facing away from the first pipe body 111, so that the pressing rod 17 can push the second pipe body 112 through the pushing part 1123.
