[0005] The technical solution adopted by the utility model is as follows:

[0006] According to the first aspect disclosed by the utility model, a valve assembly is provided, which includes a valve body, a valve core and an elastic member. The valve body has a valve cavity, an inlet end and an outlet end, and the inlet end and the outlet end are respectively communicated with the valve cavity. The valve core includes a diversion part and a sealing part. The diversion part is slidably arranged in the valve cavity and a diversion channel is provided between the diversion part and the valve body. The sealing part is fixedly arranged on the diversion part and presses against or separates from the inlet end of the valve body to control the on-off of the diversion channel.

The sealing portion of the valve core extends into the liquid storage cavity. When the sealing portion presses against the liquid outlet hole, the liquid storage cavity is cut off from the diversion channel. When the sealing portion is separated from the liquid outlet hole, the liquid storage cavity is communicated with the diversion channel. The liquid storage device of the present utility model enables the liquid flowing out through the liquid outlet hole not to pass through the elastic member inside the valve assembly, so as to prevent the elastic member from being eroded by the liquid and at the same time prevent the elastic member from contaminating the liquid.

Detailed implementation manner

[0029] The technical solutions in the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the present utility model. It should be understood that the accompanying drawings of the present utility model are only for illustrative purposes, and it is understandable for those skilled in the art to omit some well-known structures and their descriptions in the drawings. At the same time, in the description of the present utility model, if there are descriptions of terms such as "upper", "lower", "left", "right", etc. indicating orientation or position relationship, it is only based on the orientation or position relationship shown in the drawings, and is for the convenience of describing the present utility model and is a simplified description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Correspondingly, the description of the present utility model involves similar descriptions such as "first" and "second", and this description is only used to distinguish different components, and cannot be understood as indicating or implying their relative importance, any order or implicitly indicating the quantity of the indicated technical features.

[0030] A valve is a device used to control the flow of fluids. Depending on the type of fluid, valves can include gas valves or water valves, etc. Among them, gas valves are used to control and regulate the air flow and are commonly used in gas transmission systems, air compression systems, ventilation systems, etc. Water valves are used to control and regulate the water flow and are commonly used in water supply systems, drainage systems, heating systems, etc. In addition, according to the different functions of the valves, there are various types of valves such as globe valves, valve assemblies, and regulating valves. Users can select valves with different functions according to their usage requirements.

[0031] In the related art, a valve generally includes a valve body, a valve core, and a spring. A flow passage for the fluid to flow through is provided between the valve core and the valve body. The spring is sleeved on the outer wall of the valve core to connect between the valve body and the valve core. However, in the related art, the spring is usually directly exposed in the flow passage of the valve. When fluids such as liquids or gases flow through the flow passage, the spring is in contact with the fluids such as liquids or gases for a long time, resulting in the spring being easily eroded, thus reducing the service life of the spring and requiring frequent replacement, which is costly. Moreover, when the valve is used in a water supply system, the fluid flowing through the flow passage of the valve is drinking water. The spring is immersed in the drinking water for a long time and is also likely to contaminate the drinking water, affecting the drinking hygiene and drinking safety.

[0032] Therefore, the present utility model provides a valve assembly 11, which can separate the spring in the valve assembly 11 from the flow passage of the valve assembly 11, so that the fluid avoids the spring when passing through the flow passage of the valve assembly 11, thereby preventing the spring from being eroded by the fluid. At the same time, when the valve assembly 11 of the present utility model is installed in a water supply pipeline, it can also prevent the spring from contaminating the liquid in the flow passage. The valve assembly 11 provided by the present utility model can be used in fluid pipelines such as gases or liquids. At the same time, the valve assembly 11 provided by the present utility model can also be used in liquid storage devices 10 such as water buckets, kettles, oil drums, or water dispensers, and the present utility model does not make any restrictions.

[0033] See Figures 1 to 4, the valve assembly 11 provided by the present utility model will be described below. The present utility model provides a valve assembly 11, which includes a valve body 111, a valve core 112, and an elastic member 113. The valve body 111 has a valve cavity 111a, an inlet end 1111, and an outlet end 1112. The inlet end 1111 and the outlet end 1112 are respectively communicated with the valve cavity 111a. The valve core 112 includes a flow guiding portion 1121 and a sealing portion 1122. The flow guiding portion 1121 is slidably disposed in the valve cavity 111a, and a flow guiding channel 11a is provided between the flow guiding portion 1121 and the valve body 111. The sealing portion 1122 is fixedly provided on the flow guiding portion 1121 and presses against or separates from the inlet end 1111 of the valve body 111 to control the on-off of the flow guiding channel 11a. The elastic member 113 is connected between the valve core 112 and the valve body 111. Among them, an installation portion 114 is provided on the inner wall of the valve body 111, and an installation cooperation portion 115 cooperating with the installation portion 114 is provided on the flow guiding portion 1121. The installation portion 114 can slide relative to the installation cooperation portion 115 to form an installation cavity 11b isolated from the flow guiding channel 11a between the flow guiding portion 1121 and the valve body 111, and the elastic member 113 is disposed in the installation cavity 11b.

[0034] See Figure 1 and Figure 2 , it should be noted that the valve body 111 is used to support the valve core 112 and the elastic member 113. The valve cavity 111a of the valve body 111 has an inlet end 1111 and an outlet end 1112 communicating with the external space, so as to facilitate the external fluid to flow through the flow guiding channel 11a of the valve assembly 11. The valve core 112 can slide relative to the valve body 111, so that the valve core 112 can press against or separate from one of the inlet end 1111 and the outlet end 1112 of the valve body 111, and further control the conduction or isolation of the flow guiding channel 11a from the external space. Taking the valve core 112 pressing against or separating from the inlet end 1111 of the valve body 111 as an example, when the elastic member 113 is in the initial state, the valve core 112 presses against the inlet end 1111, so that the flow guiding channel 11a is not communicated with the external space to form the closed state of the valve core 112. When the elastic member 113 is compressed, the valve core 112 separates from the inlet end 1111, so that the flow guiding channel 11a is communicated with the external space to form the open state of the valve core 112.

[0035] Among them, the diversion channel 11a can be formed between the outer wall of the valve core 112 and the inner wall of the valve body 111. As an example, the valve core 112 may have a diversion portion 1121 and a sealing portion 1122 arranged oppositely. The diversion portion 1121 is slidably arranged in the valve body 111, and there is a gap between the outer wall of the diversion portion 1121 and the inner wall of the valve body 111 to form the diversion channel 11a. The sealing portion 1122 is fixedly arranged on the diversion portion 1121 and extends out from the inlet end 1111 of the valve body 111 to be separated from or pressed against the inlet end 1111. The outer diameter of the sealing portion 1122 may be larger than the inner diameter of the inlet end 1111 to facilitate the sealing portion 1122 to cover the inlet end 1111. In this way, during the sliding process of the valve core 112, when the sealing portion 1122 of the valve core 112 is pressed against and sealed with the inlet end 1111, the diversion channel 11a between the diversion portion 1121 and the inner wall of the valve body 111 is separated from the external space to form the closed state of the valve core 112. At this time, the external liquid cannot flow through the diversion channel 11a. When the sealing portion 1122 of the valve core 112 is lifted to be separated from the inlet end 1111, the diversion channel 11a between the diversion portion 1121 and the inner wall of the valve body 111 is communicated with the external space to form the open state of the valve core 112. At this time, the external liquid can flow through the diversion channel 11a.

[0036] Meanwhile, the installation cavity 11b can also be formed between the outer wall of the valve core 112 and the inner wall of the valve body 111. As an example, the installation part 114 and the installation mating part 115 are slidably fitted to form the installation cavity 11b. At this time, the installation part 114 and the installation mating part 115 can be U-shaped structures respectively, so that the installation part 114 and the installation mating part 115 are respectively provided with grooves. In this way, the installation part 114 and the installation mating part 115 can be inserted into each other, and the side wall of the installation part 114 is slidably connected to the side wall of the installation mating part 115, so that the grooves of the installation part 114 and the grooves of the installation mating part 115 can be respectively communicated to form a closed installation cavity 11b. Among them, the depth directions of the grooves of the installation part 114 and the installation mating part 115 can be respectively arranged along the length direction of the valve body 111, and the opening directions of the two grooves are opposite. In this way, during the process of the sealing part 1122 of the valve core 112 pressing against or separating from the inlet end 1111 of the valve core 112, the depth of the installation cavity 11b formed by the two grooves can change in the length direction of the valve body 111, so that the elastic member 113 in the installation cavity 11b is compressed or stretched. Of course, in other embodiments, two cavities separated left and right can also be formed between the inner wall of the valve body 111 and the outer wall of the valve core 112, one of which is used as the diversion channel 11a and the other is used as the installation cavity 11b. As an example, the valve body 111 and the valve core 112 form two cavities separated left and right, the diversion channel 11a is formed between the left inner wall of the valve body 111 and the left outer wall of the valve core 112, and the installation cavity 11b is formed between the right inner wall of the valve body 111 and the right outer wall of the valve core 112. At this time, the elastic member 113 is connected between the right inner wall of the valve body 111 and the right outer wall of the valve core 112, so that the valve core 112 can move left and right relative to the valve body 111. In the closed state of the valve core 112, the valve core 112 presses against the left inner wall of the valve body 111, so that the diversion channel 11a is closed. In the open state of the valve core 112, the valve core 112 moves towards the right inner wall of the valve body 111, so that the diversion channel 11a is opened. In addition, there are various ways to form the installation cavity 11b and the diversion channel 11a, as long as the installation cavity 11b and the diversion channel 11a are isolated from each other, so that the external fluid can avoid the elastic member 113 when flowing through the diversion channel 11a, and the present utility model does not make any restrictions.

[0037] Therefore, when the valve assembly 11 provided by the present utility model is in use, the valve body 111 can be installed in an external pipeline (such as a fluid pipeline like a gas pipeline or a liquid pipeline) or an external container (such as a liquid storage device like a kettle, a bucket, or an oil barrel). The valve core 112 is slidably arranged in the valve body 111, and a double-chamber structure in which the diversion channel 11a and the installation cavity 11b are separated is formed between the valve body 111 and the valve core 112. In the open state of the valve core 112, when the external fluid flows through the diversion channel 11a of the valve assembly 11, the external fluid can flow around the elastic member 113 in the installation cavity 11b. Through the protection of the installation cavity 11b for the elastic member 113, the elastic member 113 is prevented from being eroded by the external fluid, so as to extend the service life of the elastic member 113.

[0038] Compared with the technical solution in the related art where the elastic member 113 is directly exposed in the diversion channel 11a, the valve assembly 11 provided by the present utility model forms a double-chamber structure in which the diversion channel 11a and the installation cavity 11b are separated between the valve body 111 and the valve core 112, so that the external fluid can flow around the elastic member 113 to prevent the elastic member 113 from being eroded by the external fluid and extend the service life of the elastic member 113. At the same time, when the external fluid is drinking water, oil products or other liquids with quality requirements, the installation cavity 11b can also prevent the elastic member 113 from contacting the external liquid and polluting the external liquid, thereby ensuring the hygiene of drinking water, the quality of oil products and the use quality of other external liquids flowing through the diversion channel 11a.

[0039] See Figures 2 to 4 , in some embodiments, for the convenience of processing the valve body 111, the valve body 111 can be set as a hollow cylinder, and the opposite ends of the hollow cylinder respectively form the inlet end 1111 and the outlet end 1112 of the valve body 111. At this time, the valve cavity 111a of the valve body 111 is cylindrical, that is, the inner diameters of all parts of the valve body 111 are the same. The valve core 112 can be set as a stepped cylinder, that is, the outer diameter of the diversion part 1121 of the valve core 112 is smaller than the outer diameter of the sealing part 1122. At the same time, the outer diameter of the diversion part 1121 is smaller than the inner diameter of the valve body 111 to facilitate the sliding of the valve core 112 in the valve body 111. The outer diameter of the sealing part 1122 is larger than the inner diameter of the valve body 111 to facilitate the sealing part 1122 to seal the inlet end 1111 of the valve body 111 to close the diversion channel 11a. Of course, in other embodiments, if the inner diameter of the valve body 111 changes, such as the inner diameter of the valve body 111 gradually increases along the direction from the inlet end 1111 to the outlet end 1112, the outer diameter of the diversion part 1121 can also be set to be larger than the outer diameter of the sealing part 1122. Therefore, the outer diameter of the valve core 112 can be adjusted according to the inner diameter of the valve body 111 to form different-shaped valve cores 112 in cooperation with different-shaped valve bodies 111, and the present utility model does not limit this.

[0040] In some embodiments, to facilitate the sliding of the valve core 112 relative to the valve body 111, the valve core 112 can be slid relative to the valve body 111 by the impact of external fluid. Alternatively, the valve core 112 can also be connected to external driving mechanisms such as a pressing handle or a connecting rod structure, as well as other electronic control components, and the valve core 112 is pushed to slide relative to the valve body 111 by the external driving mechanism. The present utility model does not limit the sliding manner of the valve core 112 relative to the valve body 111.

[0041] See you later Figure 1 and Figure 2 , as an example, when the valve core 112 is driven by external fluid, the sealing portion 1122 of the valve core 112 extends out of the valve body 111 and presses against the inlet end 1111 of the valve body 111. At this time, the valve assembly 11 restricts the flow direction of the external liquid.

[0042] Specifically, when the valve core 112 slides driven by external fluid, the external fluid is only allowed to flow in the diversion channel 11a in the direction from the outlet end 1112 of the valve body 111 to the inlet end 1111 of the valve body 111. As an example, in the case where the valve core 112 extends out of the inlet end 1111 of the valve body 111 and presses against the inlet end 1111, when the external fluid flows in the direction from the outlet end 1112 of the valve body 111 to the inlet end 1111, the external fluid applies an external force to the valve core 112 in the direction from the outlet end 1112 of the valve body 111 to the inlet end 1111, and the valve core 112 slides from the outlet end 1112 of the valve body 111 towards the inlet end 1111. At this time, the spring in the installation cavity 11b is compressed, and the valve core 112 is separated from the inlet end 1111 of the valve body 111, so that the diversion channel 11a is communicated with the external space. In this way, the external fluid can flow through the diversion channel 11a. When the external fluid flows in the direction from the inlet end 1111 of the valve body 111 to the outlet end 1112, the external fluid applies an external force to the valve core 112 in the direction from the inlet end 1111 of the valve body 111 to the outlet end 1112. Since the valve core 112 presses against the inlet end 1111 of the valve body 111 in the acting direction of the external fluid, the elastic member 113 between the valve core 112 and the valve body 111 does not change, the valve core 112 is fixed relative to the valve body 111, and the diversion channel 11a cannot be communicated with the external space. At this time, the external liquid cannot flow through the diversion channel 11a. Thus, the valve assembly 11 can restrict the flow direction of the external fluid and prevent the external fluid from flowing backward.

[0043] Refer to Figure 1 and Figure 2, when the valve core 112 is driven by an external driving mechanism, if the external driving mechanism is connected to the side of the valve core 112 close to the outlet end 1112 of the valve body 111, and the inlet end 1111 of the valve body 111 is connected to the liquid storage device 10, then when the external driving mechanism pushes the valve core 112 to move along the direction from the outlet end 1112 to the inlet end 1111 of the valve body 111, the liquid in the liquid storage device 10 can flow out along the direction from the inlet end 1111 to the outlet end 1112 of the valve body 111. When the external driving mechanism does not push the valve core 112 to move, the liquid in the liquid storage device 10 cannot flow out from the diversion channel 11a, so as to prevent the liquid in the liquid storage device 10 from leaking.

[0044] It should be noted that a slot 120 can be provided on the side of the valve core 112 close to the outlet end 1112 of the valve body 111 to facilitate the connection of the external driving mechanism. At the same time, the end of the valve core 112 extending from the inlet end 1111 of the valve body 111 into the liquid storage device 10 has a sealing surface 1122a and a diversion surface 1122b. The sealing surface 1122a is used to press against or separate from the inlet end 1111 of the valve body 111 to open or close the diversion channel 11a. In the direction from the outlet end 1112 to the inlet end 1111 of the valve body 111, the diversion surface 1122b protrudes from the sealing surface 1122a to facilitate introducing the liquid in the liquid storage device 10 into the diversion channel 11a.

[0045] In some embodiments, the elastic member 113 can be an elastic body such as a spring or a rubber ring that can undergo elastic deformation. In this way, the elastic force of the elastic member 113 can make the valve core 112 fit tightly with the valve body 111, thereby improving the sealing performance of the diversion channel 11a in the closed state of the valve core 112 and preventing fluid leakage. At the same time, when the valve core 112 is reset from the open state to the closed state, the elastic member 113 can also drive the valve core 112 to quickly press against the valve body 111 to cut off the connection between the diversion channel 11a and the external space, so as to facilitate switching between the open state and the closed state of the valve core 112. In addition, the elastic member 113 can also absorb the sudden change of the force acting on the valve core 112 by the fluid or the external driving mechanism to buffer the impact force of the valve core 112 on the valve body 111, thereby protecting related equipment such as the pipeline system or the liquid storage device 10 and avoiding vibration or damage caused by pressure shock.

[0046] See Figure 3 and Figure 4 , in some embodiments, to facilitate separating the diversion channel 11a from the installation cavity 11b, the diversion channel 11a can also be formed inside the valve core 112. Specifically, the diversion portion 1121 has a cavity 1121b, an inflow hole 1121a, and an outflow hole 1121c. The inflow hole 1121a and the outflow hole 1121c are respectively communicated with the cavity 1121b to form a diversion channel 11a inside the diversion portion 1121.

[0047] In this way, a diversion channel 11a is formed inside the valve core 112, and an installation cavity 11b is formed between the outer wall of the valve core 112 and the inner wall of the valve body 111. When the external fluid flows through the diversion channel 11a, the external fluid flows inside the valve core 112, while the elastic member 113 changes between the outer wall of the valve core 112 and the inner wall of the valve body 111, and can further separate the diversion channel 11a from the installation cavity 11b to prevent the external liquid from flowing through the installation cavity 11b, thereby protecting the elastic member 113.

[0048] It should be noted that the inflow hole 1121a of the valve core 112 can be arranged on the outer side wall of the diversion portion 1121, so that the outer side wall of the valve core 112 abuts against the inner wall of the valve body 111, causing the inflow hole 1121a to close, and then closing the diversion channel 11a. The outflow hole 1121c of the valve core 112 can be arranged on the bottom wall of the valve core 112 facing the outlet end 1112 of the valve body 111, that is, the outflow hole 1121c of the valve core 112 is always in an open state. In this way, when the valve core 112 slides relative to the valve body 111, as long as the inflow hole 1121a of the valve core 112 extends out of the valve body 111, causing the inflow hole 1121a to be separated from the inner wall of the valve body 111, the diversion channel 11a can be communicated with the external space, so that the external fluid can avoid the elastic member 113 when flowing through the diversion channel 11a.

[0049] Reference Figure 1 and Figure 2 In some embodiments, for the convenience of forming the installation cavity 11b between the outer wall of the valve core 112 and the inner wall of the valve body 111, one end of the installation portion 114 away from the valve body 111 is slidably connected to the outer wall of the valve core 112, and one end of the installation fitting portion 115 away from the valve core 112 is slidably connected to the inner wall of the valve body 111. With this arrangement, a part of the inner wall of the valve body 111, the installation portion 114, a part of the outer wall of the valve core 112, and the installation fitting portion 115 jointly enclose to form the installation cavity 11b. When the valve core 112 slides relative to the valve body 111, the depth of the installation cavity 11b can change with the sliding of the valve core 112, so as to adapt to the elastic deformation of the elastic member 113.

[0050] It should be noted that the installation portion 114 can be an annular structure extending along the circumferential direction of the valve body 111, the installation fitting portion 115 can be an annular structure extending along the circumferential direction of the valve core 112, and the installation portion 114 and the installation fitting portion 115 coincide axially along the valve body 111 to cooperate with the valve core 112 and the valve body 111 to form the installation cavity 11b isolated from the diversion channel 11a. In this way, the structures of the installation portion 114 and the installation fitting portion 115 are simple, convenient to process, and convenient to assemble the valve core 112 and the valve body 111 to form the installation cavity 11b.

[0051] Meanwhile, in the direction from the inlet end 1111 of the valve body 111 towards the outlet end 1112 of the valve body 111, the installation part 114 is arranged between the installation cooperation part 115 and the inlet end 1111. With such an arrangement, when the valve core 112 slides relative to the valve body 111, in the direction from the inlet end 1111 of the valve body 111 towards the outlet end 1112, the valve core 112 can be pressed and limited by the inlet end 1111 of the valve core 112 and the valve body 111. In the direction from the outlet end 1112 of the valve body 111 towards the inlet end 1111, the cooperation between the installation part 114 and the installation cooperation part 115 can be used for limiting. Thus, the sliding distance of the valve core 112 relative to the valve body 111 is restricted, and the valve core 112 can be prevented from slipping out of the valve body 111. In addition, by restricting the sliding distance of the valve core 112 relative to the valve body 111, during the sliding process of the valve core 112, the inflow hole 1121a of the valve core 112 can also be prevented from moving into the installation cavity 11b, thereby preventing external fluid from entering the installation cavity 11b.

[0052] Reference Figure 1 and Figure 2 , in some embodiments, to prevent external fluid from entering the installation cavity 11b, the installation part 114 includes a connecting part 114a and a folding part 114b. One end of the connecting part 114a is fixedly arranged on the inner wall of the valve body 111, the other end of the connecting part 114a is connected to the folding part 114b, and the folding part 114b is arranged at an interval from the inner wall of the valve body 111 and is slidably connected to the outer wall of the valve core 112. Among them, the connecting part 114a is arranged between the inlet end 1111 of the valve body 111 and the installation cooperation part 115. In the direction from the inlet end 1111 of the valve body 111 towards the outlet end 1112 of the valve body 111, the folding part 114b protrudes from the connecting part 114a, and the end of the folding part 114b far from the connecting part 114a is arranged between the inflow hole 1121a and the installation cooperation part 115. The elastic member 113 is connected between the connecting part 114a and the installation cooperation part 115.

[0053] With such an arrangement, the installation part 114 forms a bent structure through the connection between the connecting part 114a and the folding part 114b. On the one hand, the contact area between the installation part 114 and the outer wall of the valve core 112 can be increased through the folding part 114b to increase the sliding stability of the valve core 112 relative to the valve body 111. At the same time, the end of the folding part 114b far from the connecting part 114a is arranged between the inflow hole 1121a and the installation cooperation part 115. In this way, when external fluid enters the valve body 111, the external fluid will first enter the diversion channel 11a through the inflow hole 1121a of the valve core 112 and be discharged, thereby preventing external fluid from entering the installation cavity 11b.

[0054] On the other hand, the connecting portion 114a is disposed between the inlet end 1111 of the valve body 111 and the installation and mating portion 115. The cooperation between the connecting portion 114a and the folding portion 114b forms a receiving groove. The formed receiving groove can increase the storage space for the elastic member 113, facilitating the elastic deformation of the elastic member 113 in the extending direction of the diversion channel 11a, so that the valve core 112 can slide relative to the valve body 111 to open or close the diversion channel 11a. At the same time, the receiving groove can also limit the elastic member 113 to prevent the elastic member 113 from tilting or shifting during the deformation process. In addition, the receiving groove can better protect the elastic member 113 from being eroded by external fluids.

[0055] In some embodiments, the side wall of the installation and mating portion 115 facing the installation cavity 11b may be provided with a stepped surface 115a. On the one hand, the stepped surface 115a can be used to position the elastic member 113 sleeved on the outer wall of the valve core 112 to prevent the elastic member 113 from tilting or shifting during the deformation process. On the other hand, the stepped surface 115a can also be used to increase the accommodation space 41d in the installation cavity 11b, facilitating the elastic deformation of the elastic member 113 in the extending direction of the diversion channel 11a, so that the valve core 112 can slide relative to the valve body 111 to open or close the diversion channel 11a.

[0056] See Figures 1 to 3 , in some embodiments, to prevent external fluids from entering the installation cavity 11b, the valve assembly 11 includes a first seal 116. The first seal 116 is disposed between the diversion channel 11a and the installation cavity 11b to seal the installation cavity 11b. It should be noted that the first seal 116 can further prevent external fluids from entering the installation cavity 11b. The first seal 116 can be arranged in a ring shape to uniformly seal the gap between the diversion channel 11a and the installation cavity 11b. Among them, the first seal 116 can be a rubber ring or a metal ring, and the present invention does not make any restrictions.

[0057] As an example, the first seal 116 can be disposed between the folding portion 114b and the outer wall of the valve core 112, and the distance from the first seal 116 to the inlet end 1111 of the valve body 111 is less than the distance from the inflow hole 1121a on the valve core 112 to the inlet end 1111 of the valve body 111. In this way, when the inflow hole 1121a of the valve core 112 extends out of the valve body 111 and communicates with the external space, the installation cavity 11b is in a sealed state to prevent external fluid from entering the installation cavity 11b. In addition, to facilitate fixing the first seal 116, at least one of the outer wall of the valve core 112 and the outer wall of the folding portion 114b is provided with a first installation groove 118, and the first seal 116 can be embedded in the first installation groove 118. In this way, the first installation groove 118 can increase the contact area between the first seal 116 and the valve core 112 and the installation portion 114, thereby improving the connection firmness of the first seal 116 and preventing the first seal 116 from falling off during the sliding process, so as to further improve the sealing performance of the installation cavity 11b.

[0058] In some embodiments, to improve the sealing performance of the diversion channel 11a when the valve core 112 is in the closed state, the valve assembly 11 includes a second seal 117, and the second seal 117 is disposed between the valve core 112 and the inlet end 1111 of the valve body 111 to cooperate with the valve core 112 to switch between the open state and the closed state of the valve core 112.

[0059] It should be noted that the second seal 117 can be set in a ring shape to evenly seal the gap between the valve core 112 and the valve body 111. At the same time, the second seal 117 can be sleeved on the outer wall of the valve core 112 to move synchronously with the valve core 112. When the valve core 112 abuts against the inlet end 1111, the second seal 117 is clamped between the valve core 112 and the inlet end 1111, and the diversion channel 11a is closed. When the valve core 112 is separated from the inlet end 1111, a gap appears between the second seal 117 and the inlet end 1111, and the diversion channel 11a communicates with the external space.

[0060] In addition, to facilitate fixing the valve core 112 and the second seal 117, the outer wall of the valve core 112 can be provided with a second installation groove 119, and the second seal 117 can be embedded in the second installation groove 119. In this way, the second installation groove 119 can increase the contact area between the second seal 117 and the valve core 112, thereby improving the connection firmness between the valve core 112 and the second seal 117 and preventing the second seal 117 from falling off the valve core 112.

[0061] Of course, the second seal 117 may not be fixed to the valve core 112, but fixed to the inlet end 1111 of the valve body 111. In this way, by sliding the valve core 112 relative to the inlet end 1111, the second seal 117 can also be squeezed to open or close the diversion channel 11a. The present utility model does not limit the fixing method of the second seal 117.

[0062] In addition to the above valve assembly 11, the present utility model also provides a liquid storage device 10 with the above valve assembly 11. The liquid storage device 10 will be further described below.

[0063] See Figures 5 to 7 , the liquid storage device 10 of the present utility model includes a liquid storage container 12 and the above valve assembly 11. The valve assembly 11. The liquid storage container 12 has a liquid storage cavity 1211 and a liquid outlet hole 1212 communicating with the liquid storage cavity 1211. The valve body 111 is connected to the liquid outlet hole 1212. The sealing portion 1122 of the valve core 112 extends into the liquid storage cavity 1211. When the sealing portion 1122 presses against the liquid outlet hole 1212, the liquid storage cavity 1211 is cut off from the diversion channel 11a. When the sealing portion 1122 is separated from the liquid outlet hole 1212, the liquid storage cavity 1211 communicates with the diversion channel 11a. It should be noted that the liquid storage container 12 can be a water kettle, a water bucket, an oil barrel, etc., and the present utility model does not make any restrictions.

[0064] See Figure 6 , as an example, the liquid storage container 12 provided by the present utility model includes a housing 121 and a cover 122. The housing 121 is provided with a liquid storage cavity 1211 and a liquid outlet hole 1212. The top end of the housing 121 can be set as an open end 1213, and the cover 122 can be installed on the open end 1213 in an openable and closable manner. Among them, the user can fill the liquid storage cavity 1211 with liquid through the open end 1213 of the housing 121, or pour out the liquid in the liquid storage cavity 1211 from the open end 1213 of the housing 121. Of course, when adding liquid to the liquid storage cavity 1211 of the liquid storage container 12, a cover hole can also be provided on the cover 122 to add water through the cover hole, or to connect other liquid delivery pipes through the cover hole to automatically add water to the liquid storage container 12.

[0065] In some embodiments, to facilitate the placement of the liquid storage container 12, the bottom of the housing 121 is provided with a support surface 1215 and a mounting surface 1216 that is inclined relative to the support surface 1215. Among them, the support surface 1215 is used to cooperate with other placement surfaces (such as the base 30 inside the cabinet door 40) to support the housing 121, and the mounting surface 1216 is used to provide the liquid outlet hole 1212. With this arrangement, when the housing 121 is placed on a placement surface such as a tabletop or the ground through the support surface 1215, there is an inclination angle between the mounting surface 1216 and the support surface 1215, so that the liquid outlet hole 1212 does not contact the placement surface such as the tabletop or the ground, so as to avoid contaminating the liquid outlet hole 1212.

[0066] See Figure 7 In some embodiments, when the valve assembly 11 is installed in the liquid storage container 12, the valve core 112 of the valve assembly 11 can extend from the inlet end 1111 of the valve body 111 into the liquid storage cavity 1211 of the liquid storage container 12 to press against or separate from the liquid outlet hole 1212 of the liquid storage container 12, so as to control the opening and closing of the liquid outlet hole 1212, enabling the liquid in the liquid storage container 12 to flow out from the diversion channel 11a or be stored in the liquid storage container 12.

[0067] Among them, when the liquid outlet hole 1212 of the liquid storage container 12 protrudes from the housing 121 of the liquid storage container 12, the side wall of the liquid outlet hole 1212 of the liquid storage container 12 can be used to replace the valve body 111. The valve body 111 and the liquid outlet hole 1212 of the liquid storage container 12 can also be integrally formed to simplify the assembly.

[0068] Specifically, when the liquid storage device 10 is in use, the liquid storage cavity 1211 of the liquid storage container 12 is filled with liquid. Relying on the gravity of the liquid in the liquid storage cavity 1211, the valve core 112 can be pressed against the liquid outlet hole 1212, thereby closing the diversion channel 11a and storing the liquid in the liquid storage container 12 in the liquid storage cavity 1211. When the liquid storage device 10 is placed on other external devices (such as a water dispenser body, a refrigerator door body 41, or a humidifier body, etc.), the external device can be provided with a socket that cooperates with the valve core 112, so that the socket jacks up the valve core 112 to separate the valve core 112 from the liquid outlet hole 1212. At this time, the liquid storage cavity 1211 of the liquid storage container 12 is communicated with the diversion channel 11a, enabling the liquid in the liquid storage container 12 to flow out from the diversion channel 11a.

[0069] Thus, when the liquid storage device 10 is in use, the liquid in the liquid storage container 12 does not pass through the elastic member 113 when flowing out. Such a setting can, on the one hand, prevent the elastic member 113 from being soaked in the liquid for a long time to avoid erosion of the elastic member 113 and extend the service life of the elastic member 113. On the other hand, it can also avoid contamination of the liquid by the elastic member 113 to ensure liquid hygiene.

[0070] The liquid storage device 10 provided by the present utility model can be used in devices such as water dispensers, refrigerators 1, or humidifiers, and the present utility model does not make any restrictions. Taking the refrigerator 1 as an example, the present utility model provides a refrigerator door 40 having the above liquid storage device 10. Through the cooperation of the liquid storage device 10 and the liquid outlet component 20 on the door 40, the refrigerator 1 has the function of a water dispenser to meet the user's need to access ice water.

[0071] Next, the present utility model will further describe the refrigerator door 40 of the refrigerator 1.

[0072] See Figure 8 and Figure 9, the door 40 of the present utility model includes a door body 41, a liquid discharging component 20, and the above-mentioned liquid storage device 10. The door body 41 has an inner door side 41a, an outer door side 41b, and a door hole 41c communicating the inner door side 41a and the outer door side 41b. The liquid discharging component 20 is installed in the door hole 41c, and the liquid discharging component 20 has a liquid discharging channel 20a. The liquid storage device 10 is installed on the inner door side 41a, and the liquid discharging hole 1212 of the liquid storage device 10 is connected to the liquid discharging component 20, so that the diversion channel 11a communicates with the liquid discharging channel 20a. When the sealing portion 1122 of the valve core 112 is separated from the liquid discharging hole 1212, the liquid in the liquid storage cavity 1211 flows through the diversion channel 11a and is discharged from the liquid discharging channel 20a.

[0073] It should be noted that the door 40 can be installed on the refrigerator 1 for use, and is used to open and close storage compartments such as the freezer 52 or the refrigerator compartment 51 of the refrigerator 1. Among them, the inner door side 41a of the door 40 faces the refrigerator compartment 51, and the outer door side 41b of the door 40 faces away from the refrigerator compartment 51. The liquid storage device 10 is installed on the inner door side 41a of the door 40 to cool the liquid in the liquid storage device 10 by using the refrigeration function of the refrigerator 1 to meet the user's need for taking cold drinks. At the same time, the liquid discharging component 20 is arranged in the door hole 41c of the door 40, and the liquid in the liquid storage device 10 can be led out to the outside of the door 40 through the liquid discharging channel 20a of the liquid discharging component 20, so that the user can take cold drinks outside the door 40 without repeatedly opening and closing the door 40. This can not only simplify the water-taking steps, but also avoid repeatedly opening and closing the door 40, reducing the cold leakage of the refrigerator 1.

[0074] At the same time, during the use of the door 40 of the present utility model, when the user takes water, the valve core 112 is in an open state, and the liquid in the liquid storage device 10 can flow through the diversion channel 11a into the liquid discharging channel 20a of the liquid discharging component 20 for the user to take. Since the liquid in the liquid storage device 10 does not pass through the elastic member 113 in the installation cavity 11b when flowing out, it can avoid the pollution of the drinking water by the elastic member 113, ensure the cleanliness and hygiene of the water-taking waterway of the user, and thus ensure the water-taking hygiene and drinking water safety of the user.

[0075] In some related technologies, a liquid discharging nozzle is usually used to take water from a water kettle in the refrigerator 1. Since when the water kettle is installed on the door 40, the valve core 112 in the water outlet of the water kettle is usually directly pushed up, and at this time the water outlet of the water kettle is opened, some liquid leakage will occur. Therefore, this kind of liquid discharging nozzle usually has a water storage area to collect the liquid flowing out during the installation of the water kettle. When the user takes water, the user opens the liquid discharging nozzle, and the liquid in the water kettle passes through the water storage area again and is discharged from the liquid discharging nozzle for the user to drink. However, the liquid in the water storage area of this kind of liquid discharging nozzle remains for a long time, and the liquid is prone to breed bacteria or decay in the water storage area, so that the liquid taken out by the user is polluted.

[0076] Therefore, the present utility model provides a liquid outlet component 20, see Figures 10 to 12 , the liquid outlet component 20 includes a liquid outlet housing 21 and a liquid outlet conduit 22. The liquid outlet housing 21 is installed in the door hole 41c, and the liquid outlet housing 21 has a receiving cavity 211. The liquid outlet conduit 22 is slidably connected to the inside of the liquid outlet housing 21, and the liquid outlet conduit 22 has a liquid outlet channel 20a. Among them, the liquid outlet hole 1212 of the liquid storage device 10 is connected to one end of the liquid outlet housing 21 close to the inner side 41a of the door, and the liquid outlet conduit 22 is connected to the valve core 112 to drive the valve core 112 to slide relative to the valve body 111, thereby switching the open state and the closed state of the valve core 112.

[0077] With such a setting, when an external force acts on the liquid outlet conduit 22, the liquid outlet conduit 22 can move axially along the door hole 41c relative to the liquid outlet housing 21, thereby pushing the valve core 112 in the liquid storage device 10 to slide, so that the valve core 112 abuts against or separates from the liquid outlet hole 1212 to switch the open state and the closed state of the valve core 112. As an example, when no external force acts on the liquid outlet conduit 22, the elastic member 113 in the valve body 111 causes the valve core 112 to abut against the liquid outlet hole 1212, isolating the liquid storage cavity 1211 of the liquid storage device 10 from the diversion channel 11a, and the liquid in the liquid storage cavity 1211 cannot flow out, and the cabinet door 40 is in a state of not taking water. When the user takes water from the liquid storage device 10, the liquid outlet conduit 22 moves in the direction from the outlet end 1112 of the valve body 111 to the inlet end 1111 under force, the elastic member 113 is squeezed, and the valve core 112 is separated from the liquid outlet hole 1212, so that the liquid in the liquid storage device 10 flows through the diversion channel 11a and flows out from the liquid outlet channel 20a.

[0078] Compared with the related art, during the water-taking process of the cabinet door 40 provided by the present utility model, the user only needs to push the liquid outlet conduit 22 to take water from the liquid storage device 10, and the water-taking is simple and convenient. Moreover, the liquid taken out by the user can directly flow through the diversion channel 11a and the liquid outlet channel 20a and be discharged, avoiding the taken liquid from accumulating in the diversion channel 11a or the liquid outlet channel 20a for a long time, thereby preventing the taken liquid from spoiling and ensuring the water-taking hygiene and drinking water safety of the user.

[0079] See Figure 11 , in some embodiments, to facilitate pushing the liquid outlet conduit 22, the door body 41 of the cabinet door 40 has a distribution component 42. The distribution component 42 includes a distribution housing 421 and a force-receiving part 422. The distribution housing 421 is installed on the outer side 41b of the door body 41. The force-receiving part 422 is rotatably connected to the distribution housing 421, and the force-receiving part 422 is connected to the liquid outlet conduit 22.

[0080] As an example, the force-receiving part 422 is set as a tongue depressor. The top end of the tongue depressor is rotatably connected to the dispensing housing 421, and the bottom end of the tongue depressor is set as a free end. A torsion spring is provided between the dispensing housing 421 and the tongue depressor. When the user takes water, the user presses the free end of the tongue depressor, the torsion spring deforms, and the tongue depressor can rotate around the top end of the tongue depressor to push the liquid outlet conduit 22 to slide relative to the liquid outlet housing 21 in the direction pointing from the liquid outlet end of the valve body 111 to the inlet end 1111. Furthermore, the liquid outlet conduit 22 is used to lift the valve core 112, so that the elastic member 113 in the valve assembly 11 is compressed to separate the valve core 112 from the liquid outlet hole 1212. At this time, the liquid storage chamber 1211 of the liquid storage device 10 is communicated with the diversion channel 11a, and the liquid in the liquid storage device 10 can flow out from the liquid outlet channel 20a through the diversion channel 11a to meet the water-taking needs of the user.

[0081] When the user cancels the pressing on the tongue depressor, the torsion spring restores its deformation to reset the tongue depressor from the pressing position to the idle position. And the tongue depressor drives the liquid outlet conduit 22 to separate from the valve core 112, and the elastic member 113 in the valve assembly 11 restores its deformation so that the valve core 112 presses against the liquid outlet hole 1212 of the liquid storage device 10. At this time, the liquid storage chamber 1211 of the liquid storage device 10 is separated from the diversion channel 11a, and the liquid in the liquid storage device 10 cannot flow out from the liquid outlet channel 20a through the diversion channel 11a to stop water taking.

[0082] Among them, the door body 41 of the door 40 includes a door outer shell and a door inner liner. Refer to Figure 8 and Figure 9 , the door outer shell forms the outer side 41b of the door body 41, and the door inner liner forms the inner side 41a of the door body 41. To facilitate the installation of the dispensing component 42 on the door body 41, a part of the outer side 41b of the door body 41 is recessed towards the inner side 41a to form an accommodation space 41d, and the door hole 41c of the door body 41 is communicated with the accommodation space 41d. The dispensing housing 421 of the dispensing component 42 can be installed in the accommodation space 41d to achieve a neat and beautiful appearance of the door 40.

[0083] Refer to Figures 11 to 13 , in some embodiments, to ensure that the liquid outlet conduit 22 can smoothly lift the valve core 112, a first limiting portion 221 is provided on the outer wall of the liquid outlet conduit 22, and the first limiting portion 221 is slidably connected to the inner wall of the liquid outlet housing 21 to limit the distance between the outer wall of the liquid outlet conduit 22 and the inner wall of the liquid outlet housing 21.

[0084] It should be noted that, since the first limiting portion 221 is provided on the outer wall of the liquid outlet conduit 22, during the sliding process of the liquid outlet conduit 22, the distance between the outer wall of the liquid outlet conduit 22 and the inner wall of the liquid outlet housing 21 always remains the same, so that the liquid outlet conduit 22 can align with the valve core 112 in the valve body 111 and smoothly lift the valve core 112 to conduct the liquid storage chamber 1211 of the liquid storage device 10 and the diversion channel 11a.

[0085] As an example, when the liquid outlet conduit 22 and the liquid outlet housing 21 are respectively arranged as cylinders, the first limiting portion 221 can be arranged as a ring along the circumferential direction of the liquid outlet conduit 22, so that the liquid outlet conduit 22 and the liquid outlet housing 21 are coaxially arranged, and further the liquid outlet conduit 22 and the valve core 112 are coaxially arranged, so as to facilitate the liquid outlet conduit 22 to lift the valve core 112.

[0086] See Figure 13 , in some embodiments, to improve the sliding stability between the liquid outlet conduit 22 and the liquid outlet housing 21, the first limiting portion 221 can also be provided with a flange 221a, and the flange 221a is in sliding contact with the inner wall of the liquid outlet housing 21. In this way, the contact area between the liquid outlet housing 21 and the liquid storage conduit can be increased through the flange 221a, further preventing the liquid outlet conduit 22 from shaking or tilting relative to the liquid outlet housing 21, and the structural strength of the first limiting portion 221 can also be increased through the flange 221a. Thus, the sliding stability between the liquid outlet conduit 22 and the liquid outlet housing 21 is improved.

[0087] In some embodiments, to limit the distance that the liquid outlet conduit 22 lifts the valve core 112, a limiting and mating portion 222 is provided on the inner wall of the liquid outlet housing 21. The first limiting portion 221 and the limiting and mating portion 222 are arranged at intervals along the length direction of the liquid outlet conduit 22, and the limiting and mating portion 222 is arranged between the first limiting portion 221 and the valve core 112, so as to limit the moving distance of the liquid outlet conduit 22 towards the valve core 112 through the cooperation between the first limiting portion 221 and the limiting and mating portion 222.

[0088] It should be noted that the moving distance of the liquid outlet conduit 22 towards the valve core 112 can be limited through the mutual cooperation between the first limiting portion 221 and the limiting and mating portion 222, so as to avoid the liquid outlet conduit 22 lifting the valve core 112 excessively and damaging the valve assembly 11. As an example, the limiting and mating portion 222 can be a boss provided on the inner wall of the liquid outlet housing 21, and the limiting and mating portion 222 is arranged between the first limiting portion 221 and the valve core 112. In this way, when the liquid outlet conduit 22 moves towards the valve core 112, the first limiting portion 221 can be pressed against the limiting and mating portion 222 to limit the liquid outlet conduit 22 from continuing to move towards the valve core 112, so as to ensure that the liquid outlet conduit 22 lifts the valve core 112 by an appropriate distance.

[0089] In some embodiments, to limit the distance that the liquid outlet conduit 22 moves away from the valve core 112, a second limiting portion 223 is provided on the outer wall of the liquid outlet conduit 22. The second limiting portion 223 and the first limiting portion 221 are arranged at intervals along the length direction of the liquid outlet conduit 22, and the second limiting portion 223 is arranged between the limiting and mating portion 222 and the valve core 112, so as to limit the moving distance of the liquid outlet conduit 22 away from the valve core 112 through the cooperation between the second limiting portion 223 and the limiting and mating portion 222.

[0090] As an example, the second limiting portion 223 may be a flange provided on the outer wall of the liquid outlet conduit 22. When the liquid outlet conduit 22 moves away from the valve core 112, the second limiting portion 223 can be pressed against the limiting and mating portion 222 to limit the distance of the liquid outlet conduit 22 from the valve core 112 and prevent the liquid outlet conduit 22 from slipping out of the liquid outlet housing 21. Optionally, the second limiting portion 223 may also be a groove on the outer wall of the liquid outlet conduit 22. At this time, the limiting and mating portion 222 is an elastic body with elasticity. During the sliding process of the liquid outlet conduit 22, the limiting and mating portion 222 can be inserted into the second limiting portion 223 to limit the sliding of the liquid outlet conduit 22 relative to the liquid outlet housing 21.

[0091] See Figure 11 and Figure 12 , in some embodiments, to facilitate the liquid outlet conduit 22 to lift the valve core 112, one of the liquid outlet conduit 22 and the valve core 112 is provided with a plugging portion 224, and the other of the liquid outlet conduit 22 and the valve core 112 is provided with a slot 120. The plugging portion 224 is plugged into the slot 120. With this setting, through the cooperation of the slot 120 and the plugging portion 224, the liquid outlet conduit 22 and the valve core 112 can be coaxially arranged, avoiding the liquid outlet conduit 22 from shifting during the sliding process and being unable to lift the valve core 112. Optionally, a slot 120 is provided at one end of the valve core 112 facing the liquid outlet conduit 22, and the plugging portion 224 is formed on the side wall of the end of the liquid outlet conduit 22 facing the valve core 112.

[0092] In addition, when the external fluid flows out through the diversion channel 11a, through the plugging fit formed by the plugging portion 224 and the slot 120 between the liquid outlet conduit 22 and the valve core 112, the external fluid can also be prevented from entering the installation cavity 11b from the outlet end 1112 of the diversion channel 11a.

[0093] See Figure 12 , in some embodiments, to avoid the valve core 112 being lifted in advance when the liquid storage device 10 is placed on the box door 40, resulting in the leakage of the liquid in the liquid storage device 10, a safety gap 226 is provided between the plugging portion 224 and the slot 120 along the moving direction of the liquid outlet conduit 22.

[0094] It should be noted that when the liquid storage device 10 is installed on the box door 40, although the valve core 112 and the liquid outlet conduit 22 are plugged into each other. However, at this time, the liquid outlet conduit 22 does not lift the valve core 112. Only when the user takes water, the liquid outlet conduit 22 will lift the valve core 112 to conduct the liquid storage device 10 and the diversion channel 11a.

[0095] After the door body 41 is processed, in order to improve the heat insulation performance of the door body 41, the door body 41 needs to be foamed. Through the safety gap 226 between the insertion part 224 and the slot 120, the installation error caused by foaming can be avoided, and it can be prevented that during the installation process of the liquid storage device 10, the liquid outlet conduit 22 prematurely pushes up the valve core 112, resulting in the leakage of the liquid in the liquid storage device 10 and abnormal water discharge. Optionally, the safety gap 226 can be set to corresponding dimensions such as 1 mm, 2 mm, 3 mm or 4 mm, etc., and the present utility model does not make any restrictions.

[0096] In some embodiments, in order to facilitate the liquid outlet conduit 22 to push the valve core 112 to move, a pushing part 225 is further provided on the outer wall of the liquid outlet conduit 22. The pushing part 225 can be in contact with or separated from the valve core 112 to push the valve core 112 to slide relative to the valve body 111. At the same time, in order to prevent the valve assembly 11 from discharging water abnormally, a safety gap 226 is also provided between the pushing part 225 and the valve core 112. Optionally, a flange can be provided on the outer wall of the liquid outlet conduit 22 to form the pushing part 225.

[0097] See Figure 13 , in some embodiments, in order to facilitate the processing of the liquid outlet conduit 22, the liquid outlet conduit 22 includes a first conduit 22a and a second conduit 22b. The first conduit 22a is connected to the valve core 112 and is slidably connected to the inner wall of the liquid outlet housing 21. The second conduit 22b is communicated with the first conduit 22a, and the second conduit 22b extends out from one end of the liquid outlet housing 21 close to the outer side 41b of the door. By setting the liquid outlet conduit 22 as a split structure in this way, the first conduit 22a and the second conduit 22b can be processed and assembled separately to improve the processing efficiency. The first conduit 22a and the second conduit 22b can be fixed by various connection methods such as threaded connection, welding or insertion. At the same time, the first limiting part 221 can be provided on the second conduit 22b, and the second limiting part 223 can be provided on the first conduit 22a.

[0098] In some embodiments, in order to facilitate smooth water intake, in the direction from the inner side 41a of the door to the outer side 41b of the door, the valve core 112, the first conduit 22a and the second conduit 22b are coaxially arranged in sequence. With this arrangement, the liquid outlet channel 20a and the diversion channel 11a extend along the same straight line, which can shorten the liquid flow path and save the water intake time. In addition, the liquid outlet channel 20a, the diversion channel 11a and the door hole 41c can also be coaxially arranged to improve the structural compactness of the door 40. Of course, in other embodiments, when the water intake water path needs to be set as a curved water path, the first conduit 22a and the second conduit 22b can also be set as bent pipes, and the present utility model does not make any restrictions.

[0099] In some embodiments, to prevent liquid from leaking outside the liquid outlet channel during water intake, along the direction of liquid flow in the liquid storage cavity 1211, the outlet size of the diversion channel 11a is smaller than the inner diameter of the inlet end of the first conduit 22a, and the inner diameter of the outlet end of the first conduit 22a is smaller than the inner diameter of the inlet end of the second conduit 22b.

[0100] With such a setting, when the liquid storage device 10 is installed with the liquid outlet component 20, the liquid outlet hole 1212 of the liquid storage device 10 is inserted into the interior of the first conduit 22a, and the first conduit 22a is inserted into the interior of the second conduit 22b, such that the inner diameter of the flow channel through which the liquid flows out of the liquid storage device 10 gradually expands layer by layer, which can ensure that during water intake, the liquid does not overflow from the side wall of the flow channel. Moreover, during water intake, the inner diameter of the liquid flow channel gradually expands layer by layer, which can also increase the water intake amount to improve the water intake efficiency.

[0101] In some embodiments, to facilitate removing the liquid outlet component 20 from the door hole 41c of the door 40, an anti-slip portion 212 is provided on the outer wall of the liquid outlet housing 21. Specifically, a flange protruding beyond the main body is provided on the outer wall of the liquid outlet housing 21, and this flange forms the anti-slip portion 212, so as to facilitate a user to hold the flange and apply an external force to the liquid outlet housing 21 to pull out the liquid outlet component 20 from the door hole 41c. Meanwhile, the outer wall of the flange can be set to shapes such as square, circular, oval, or polygonal, and the present utility model does not make any restrictions. In addition, a plurality of anti-slip ribs can be provided on the outer wall of the flange to increase the friction force on the flange. Optionally, the anti-slip ribs can be set to shapes such as spiral, wavy, or linear, and the present utility model does not make any restrictions.

[0102] See you later Figure 11 In some embodiments, the door 40 further includes a cold leakage seal 43. The cold leakage seal 43 is disposed in the door hole 41c to seal the installation gap between the door hole 41c and the liquid outlet component 20, thereby preventing the cold air inside the refrigerator 1 from leaking. Among them, the cold leakage seal 43 includes a sleeve 431, a pressing cap 432, and a sealing ring 433. The sleeve 431 is disposed on the inner wall of the door hole 41c, and the sealing ring 433 is disposed between the sleeve 431 and the liquid outlet housing 21. The top end of the sealing ring 433 is fixed to the sleeve 431 through the pressing cap 432 to prevent the sealing ring 433 from falling off.

[0103] In some embodiments, to facilitate disassembling the liquid storage device 10 and the liquid outlet component 20 from the door 40, the door 40 includes a base 30. The base 30 is fixedly provided on the inner side 41a of the door. One end of the liquid outlet housing 21 extends out of the door hole 41c to be detachably connected to the base 30. The liquid storage device 10 is slidably connected to the base 30 so that the valve core 112 cooperates with the liquid outlet conduit 22.

[0104] See Figure 11 and Figure 14, It should be noted that the base 30 is installed on the inner side 41a of the door body 41, and can be used to cooperate with the liquid outlet component 20 for detachable connection, and can also be used to support the liquid storage device 10. The base 30 is provided with a connection hole 31, and the connection hole 31 of the base 30 corresponds to the door hole 41c of the door body 41. The liquid outlet component 20 is installed in the door hole 41c, and the top end of the liquid outlet component 20 is used for inserting into the liquid outlet hole 1212 of the liquid storage device 10, and the bottom end of the liquid outlet component 20 extends from the door hole 41c to the outer side 41b of the door.

[0105] When the user installs the liquid storage device 10 on the door 40 of the box, since the liquid storage device 10 is usually heavy due to containing a large amount of liquid, in order to facilitate the user to install the liquid storage device 10 on the base 30, the base 30 is provided with at least one sliding guiding part, and the liquid storage device 10 is provided with at least one sliding guiding cooperation part. Each sliding guiding part is slidably connected with each sliding guiding cooperation part, so that the liquid outlet hole 1212 of the liquid storage device 10 is inserted into the liquid outlet component 20.

[0106] When the user disassembles the liquid storage device 10 from the door 40 of the box, the user only needs to lift the liquid storage device 10, so that the liquid outlet hole 1212 of the liquid storage device 10 can be pulled out from the liquid outlet component 20 to separate the liquid storage device 10 from the door 40 of the box, which is convenient for the user to directly take the liquid storage device 10 to pour out a large amount of ice water.

[0107] In some embodiments, in order to facilitate the disassembly and assembly of the liquid outlet component 20 and the base 30, the base 30 has a connection hole 31, and at least one positioning part 32 is provided on the inner wall of the connection hole 31, and at least one positioning cooperation part 227 is provided on the outer wall of the liquid outlet housing 21. The positioning part 32 includes a disassembly part 322 and a fixing part 321, and the disassembly part 322 and the fixing part 321 are misaligned and connected along the axial direction of the connection hole 31. The liquid outlet housing 21 is arranged in the connection hole 31, so that the positioning cooperation part 227 can move between the disassembly part 322 and the fixing part 321, so that the liquid outlet component 20 has a locked state fixed to the base 30 and a disassembled state separated from the base 30.

[0108] Among them, the positioning part 32 can be set as a groove, and the positioning cooperation part 227 can be set as an elastic convex block. During the installation of the liquid outlet component 20 on the base 30, the liquid outlet housing 21 is inserted into the connection hole 31, so that the convex block moves through the disassembly part 322 to the fixing part 321 to fix the liquid outlet component 20 and the base 30. During the disassembly process of the liquid outlet component 20 and the base 30, the liquid outlet housing 21 is rotated, so that the convex block moves out of the fixing part 321 to the disassembly part 322 to release the fixed cooperation between the liquid outlet component 20 and the base 30.

[0109] In this way, by utilizing the misaligned engagement between the positioning cooperation part 227 and the positioning part 32, the position of the convex block between the fixing part 321 and the disassembly part 322 can be changed through the rotation action between the liquid outlet component 20 and the base 30, thereby realizing the disassembly and locking of the liquid outlet component 20 and the base 30. It is simple, convenient, time-saving and labor-saving. Of course, the connection between the liquid outlet component 20 and the base 30 can also be in the form of plug-in connection, magnetic attraction cooperation or buckle cooperation, etc., and the present utility model does not make any restrictions.

[0110] See Figure 15 , the present utility model also provides a refrigerator 1 applying the above-mentioned door 40 to improve the user experience of using the refrigerator 1. The refrigerator 1 will be described below. The refrigerator 1 provided by the present utility model includes a box body 50 and the above-mentioned door 40. The box body 50 includes a refrigerating chamber 51, and the door body 41 is connected to the box body 50 to open and close the refrigerating chamber 51. Among them, the inner side 41a of the door faces the refrigerating chamber 51, and the outer side 41b of the door faces away from the refrigerating chamber 51. The liquid storage device 10 is arranged on the side of the door body 41 facing the refrigerating chamber 51 to cool the liquid in the liquid storage device 10 by using the refrigeration function of the refrigerator 1. The liquid outlet component 20 is arranged on the side of the door body 41 facing away from the refrigerating chamber 51, so that the user can press the pressing tongue outside the door 40 to take the ice water in the liquid storage device 10, thereby reducing the opening and closing of the door 40 and reducing the cold leakage of the refrigerator 1.

[0111] When the user takes water from the refrigerator 1, the liquid in the liquid storage device 10 flows out through the diversion channel and the liquid outlet channel in sequence. Since the liquid does not pass through the elastic member when flowing through the diversion channel, and the liquid can directly act on the valve assembly of the liquid storage device through the liquid outlet component, the liquid can directly flow out from the liquid outlet channel without accumulating for a long time, thereby ensuring the cleanliness and hygiene of the water intake waterway of the user. In addition, since the base 30 is installed on the door 40, through the detachable connection between the liquid storage device 10, the liquid outlet component 20 and the base 30, the liquid storage device 10 and the liquid outlet component 20 can be detached from the door 40 respectively for the user to clean or replace, further ensuring the water intake hygiene of the user and improving the user experience of using the refrigerator 1.

[0112] In some embodiments, the box body 50 may also have at least one of a freezing chamber 52, a variable temperature chamber and a fresh-keeping chamber, and the present utility model does not make any restrictions. Regarding other structures of the refrigerator 1, the present utility model will not be elaborated.
