SUMMARY

[0004] Therefore, the utility model aims at providing a liner assembly and a drinking water equipment, which can improve the sealing performance of the installation of the water outlet valve and reduce the probability of water leakage at the water outlet valve.

[0005] The first aspect embodiment of the utility model provides a liner assembly, which comprises: a liner, a water outlet is arranged on the bottom wall of the liner; a water outlet valve is arranged at the water outlet and can communicate with the inner cavity of the liner, a connecting thread is arranged on the outer side wall of the water outlet valve, and a limiting table is arranged above the connecting thread and protrudes outward in the circumferential direction, the outer diameter of the limiting table is greater than the inner diameter of the water outlet; and a connecting nut is screwed on the connecting thread to clamp the wall surface around the water outlet between the connecting nut and the limiting table.

[0006] The liner assembly provided in the embodiment sets the water outlet on the bottom wall of the liner and the water outlet valve at the water outlet, which facilitates water outlet from the bottom of the liner. When installing the water outlet valve, the water outlet valve can be inserted into the water outlet from top to bottom, and the connecting nut can be sleeved around the water outlet valve from below and be threadedly connected with the connecting thread around the water outlet valve, so as to clamp the wall surface around the water outlet between the connecting nut and the limiting table of the valve body, the connecting nut has good fastening performance, can improve the sealing performance between the water outlet valve and the water outlet, and can maintain the locking force even in a high-temperature environment, so as to reduce the probability of water leakage at the water outlet valve and solve the problem of water leakage at the water outlet valve caused by the deformation of the positioning ring in the related art.

[0007] ​Further, in some embodiments, the water outlet valve comprises: a valve body, which is of an integrated structure, the connecting thread and the limiting platform are both arranged on the outer sidewall of the valve body; a valve core, which is movably arranged in the valve body; and a valve sealing element, which is arranged in the interior of the valve body and below the valve core, the valve core can be pressed against the valve sealing element to close the water outlet valve, and the valve core can also be lifted away from the valve sealing element to open the water outlet valve.

[0008] In these embodiments, the valve body is of an integrated structure, and the connecting thread and the limiting platform are both arranged on the outer sidewall of the valve body, thereby reducing the number of components and saving costs. The valve core and the valve sealing element are both arranged in the interior of the valve body, thereby having a compact structure. When the inner container assembly is not placed in the machine body, the valve core can be pressed against the valve sealing element by its own gravity, which can effectively prevent the liquid in the inner container from leaking out through the water outlet valve. When the inner container assembly is placed in the machine body, the valve core can be lifted, thereby opening the water outlet valve and facilitating water outlet.

[0009] Further, in some embodiments, the connecting nut is a metal nut, and the valve body is a metal valve body.

[0010] The positioning ring and the valve body in the related art are usually plastic parts, which are soaked in boiling water for a long time and have the risk of aging and water leakage. In the present embodiments, the connecting nut and the valve body are both made of metal, thereby strengthening the stability of the overall structure. The connecting threads on the connecting nut and the valve body will not deform in a high-temperature environment, which can effectively ensure the sealing of the connection between the two and avoid water leakage. Moreover, metal materials are more hygienic and have a longer service life, which can effectively ensure the hygiene during use. In addition, metal materials have high strength and good toughness, and are not easy to be damaged even after long-term and frequent use, which can significantly prolong the service life of the product and reduce the frequency and cost of product replacement for users.

[0011] Further, in some embodiments, the inner container assembly further comprises: a gasket, which is arranged around the outer periphery of the water outlet valve and clamped between the wall surface around the water outlet and the connecting nut. In this way, the connecting nut can be prevented from rubbing against the wall surface around the water outlet during the process of screwing the connecting nut, and the wall surface around the water outlet can be prevented from being worn.

[0012] Further, in some embodiments, the inner container assembly further comprises: a sealing element, which is arranged around the outer periphery of the water outlet valve and clamped between the limiting platform and the surface around the water outlet. In this way, the water in the inner container can be prevented from leaking out through the gap between the water outlet and the valve body, thereby improving the sealing between the two. Moreover, the sealing element is usually an elastic element, which, in cooperation with the connecting nut, can press the wall surface around the water outlet against the limiting platform, and can also cause the sealing element to be deformed under pressure, thereby causing the sealing element to tightly fit the limiting platform and the wall surface around the water outlet, and further improving the sealing effect.

[0013] Furthermore, in some embodiments, the inner tank assembly also includes a filter screen, disposed at the water outlet and located at the top of the water outlet valve. This design ensures that the liquid in the inner tank is filtered through the filter screen before entering the water outlet valve, preventing impurities in the inner tank from entering the water outlet valve, or even entering components such as the water pump through the water outlet valve, thus avoiding blockages and damage to components.

[0014] Furthermore, in some embodiments, the outlet valve further includes an elastic element disposed inside the valve body, used to press the valve core against the valve seal to close the outlet valve. This design helps to improve the closing effect of the outlet valve and prevent liquid leakage.

[0015] Furthermore, in some embodiments, the outlet valve further includes a positioning element disposed at the bottom of the filter screen, with the top end of the elastic element fixed to the positioning element and the bottom end of the elastic element pressing against the valve core. The positioning element design limits the top end of the elastic element, allowing it to extend and deform within a set range, preventing the elastic element from shifting and affecting the accurate actuation of the valve core, thereby preventing leakage due to incomplete closure of the outlet valve. Moreover, installing the positioning element on the filter screen, compared to installing it on the valve body, eliminates the need to modify the valve body structure, facilitating valve body processing and assembly.

[0016] Furthermore, in some embodiments, the bottom wall of the inner liner is recessed in the middle to form a platform, and the outlet is located on the platform. The upper surface of the filter screen is lower than or flush with the upper surface of the bottom wall of the inner liner at the edge. This design facilitates better flow of liquid in the inner liner to the lower-positioned filter screen and out through the outlet. Moreover, the filter screen does not protrude abruptly, making it convenient for users to clean the inner liner without easily scratching the filter screen.

[0017] Furthermore, in some embodiments, a filter screen is disposed on the top of the valve body. The filter screen includes a top wall and a side wall. The top wall is provided with a plurality of first filter holes, which are connected to the inner cavity of the valve body through the top opening of the valve body. The side wall is provided with a plurality of second filter holes. The top of the outer side wall of the valve body is provided with a plurality of through holes, and each second filter hole is connected to the inner cavity of the valve body through a through hole.

[0018] In these embodiments, the mesh sidewall has a second filter hole, so that the liquid in the inner tank can enter the water outlet valve not only through the first filter hole on the top wall of the mesh, but also through the second filter hole on the side and the through hole of the valve body. This facilitates water intake from multiple directions and avoids a large amount of liquid residue in the inner tank.

[0019] A second aspect of this utility model provides a drinking water device, which includes an inner tank assembly as described in any of the above embodiments.

[0020] The water drinking equipment provided by the embodiments of the present application has the inner container assembly of any of the above embodiments, and thus has the beneficial effects of any of the above embodiments, which will not be repeated here.

[0021] Further, in some embodiments, the bottom of the inner container is further provided with a heating element and an upper coupler electrically connected with the heating element, and the water drinking equipment further comprises: a body, an outer side of the body being provided with a water outlet nozzle, an inner part of the body having a containing cavity, the inner container assembly being detachably placed in the containing cavity; a lower coupler provided on a cavity bottom wall of the containing cavity and used for cooperating with the upper coupler; a valve core lifting element provided in a middle part of the lower coupler and used for lifting a valve core of the water outlet valve when the inner container assembly is placed in the containing cavity; and a water outlet pipe, one end of the water outlet pipe extending into the middle part of the lower coupler and used for communicating with the water outlet valve, and the other end of the water outlet pipe communicating with the water outlet nozzle.

[0022] In these embodiments, the inner container assembly is detachably placed in the containing cavity, so that the inner container assembly can be taken out alone for water filling, cleaning and other operations. Moreover, after the inner container assembly is placed in the containing cavity, the valve core of the water outlet valve can be lifted by the valve core lifting element at the bottom of the containing cavity, so that the water outlet valve is opened, the water drinking equipment is facilitated to draw liquid from the inner container to the water outlet nozzle, and the user is facilitated to get water at the water outlet nozzle.

[0058] The following will combine Figures 5 to 14 This invention introduces the inner tank assembly and drinking water device provided by embodiments of the present invention.

[0059] like Figures 5 to 10 As shown, a first aspect of this utility model provides an inner liner assembly, which includes: an inner liner 100, with an outlet 111 provided on the bottom wall of the inner liner 100; an outlet valve 200, which is provided at the outlet 111 and can communicate with the inner cavity of the inner liner 100, with a connecting thread 211 and a limiting platform 212 located above the connecting thread 211 and protruding outward in a circumferential direction on the outer wall of the outlet valve 200, the outer diameter of the limiting platform 212 being larger than the inner diameter of the outlet 111; and a connecting nut 300, which can be screwed onto the connecting thread 211 to clamp the walls around the outlet 111 between the connecting nut 300 and the limiting platform 212.

[0060] The inner container assembly provided by the embodiment is provided with the water outlet 111 and the water outlet valve 200 located at the water outlet 111 on the bottom wall of the inner container 100, facilitating water outlet from the bottom of the inner container 100. When the water outlet valve 200 is installed, the water outlet valve 200 can be inserted into the water outlet 111 from top to bottom, so that the limiting table 212 is arranged on the wall surface around the water outlet 111, then the connecting nut 300 is sleeved on the outer periphery of the water outlet valve 200 from below and is threadedly connected with the connecting thread 211 on the outer periphery of the water outlet valve 200, so as to clamp the wall surface around the water outlet 111 between the connecting nut 300 and the limiting table 212 of the valve body 210. The connecting nut 300 has good fastening property, can improve the sealing property between the water outlet valve 200 and the water outlet 111, and can maintain the locking force even in a high-temperature environment for a long time, so as to reduce the probability of water leakage at the water outlet valve 200, solve the quality problem of water leakage at the water outlet valve 200 caused by the deformation of the positioning ring in the related art, improve the use safety and service life of the product, and improve the user experience when the product is used.

[0061] Moreover, compared with the connection of the positioning ring and the valve body 210 through the three clamping claws in the related art, the connecting nut 300 is connected with the valve body 210 in the circumferential direction, the locking force of the connecting nut 300 on the valve body 210 is distributed more uniformly in the circumferential direction, and the sealing property is better. In addition, the threaded connection greatly improves the convenience of installation. In the production line installation link, workers do not need complex operation skills and tools to quickly complete the installation process of the water outlet valve 200, which greatly shortens the assembly time of a single product, can effectively improve the production efficiency, reduce the cost of the whole machine, and improve the production capacity.

[0062] For the specific structure of the water outlet valve 200, further, in some embodiments, as shown in Figure 6 the water outlet valve 200 includes: a valve body 210, which is of an integrated structure, the connecting thread 211 and the limiting table 212 are arranged on the outer side wall of the valve body 210; a valve core 220, which is movably arranged in the valve body 210; a valve sealing member 230, which is arranged in the interior of the valve body 210 and below the valve core 220, the valve core 220 can be pressed against the valve sealing member 230 to close the water outlet valve 200, and the valve core 220 can be lifted away from the valve sealing member 230 to open the water outlet valve 200.

[0063] In these embodiments, the valve body 210 is a one-piece structure, with the connecting thread 211 and the limiting platform 212 both located on the outer wall of the valve body 210, reducing the number of parts and saving costs. The valve core 220 and the valve seal 230 are both located inside the valve body 210, resulting in a compact structure. When the inner tank assembly is not placed in the machine body 800, the valve core 220 can be pressed against the valve seal 230 by its own weight, effectively preventing liquid in the inner tank 100 from leaking out through the water outlet valve 200. When the inner tank assembly is placed in the machine body 800, the valve core 220 can be lifted, thereby opening the water outlet valve 200 for convenient water dispensing.

[0064] As an example, such as Figure 6 As shown, the valve seal 230 is a valve sealing ring fixed inside the valve body 210 and distributed circumferentially along the inner sidewall of the valve body 210. It does not affect the flow of liquid and can form a sealing fit with the valve core 220.

[0065] As an example, such as Figure 6 As shown, valve core 220 is a spherical valve core, such as a steel ball. The spherical valve core can fit tightly with the valve sealing ring in the circumferential direction, ensuring good closure when the outlet valve 200 is in the closed state. Of course, valve core 220 can also be in the form of a block or plate, etc., which will not be listed here.

[0066] Furthermore, in some embodiments, such as Figure 6 As shown, the outlet valve 200 also includes an elastic element 240, disposed inside the valve body 210, used to press the valve core 220 against the valve seal 230 to close the outlet valve 200. This design helps to improve the closing effect of the outlet valve 200 and prevent liquid leakage.

[0067] As an example, such as Figure 6 As shown, the elastic element 240 is a spring. It has good elasticity and restoring force, and it does not affect the flow of liquid.

[0068] Furthermore, in some embodiments, such as Figure 6 As shown, the inner tank assembly also includes a filter screen 600, which is located at the water outlet 111 and on top of the water outlet valve 200. This design ensures that the liquid in the inner tank 100 is filtered through the filter screen 600 before entering the water outlet valve 200, preventing impurities in the inner tank 100 from entering the water outlet valve 200, or even entering components such as the water pump through the water outlet valve 200, thus avoiding blockages and damage to components.

[0069] In this case, when the outlet valve 200 includes an elastic element 240, the elastic element 240 can be supported between the filter screen 600 and the valve core 220.

[0070] Of course, such as Figure 6As shown, the water outlet valve 200 can further comprise a positioning member 250, which is arranged at the bottom of the filter screen 600, the top end of the elastic member 240 is fixed on the positioning member 250, and the bottom end of the elastic member 240 is pressed against the valve core 220. The positioning member 250 limits the top end of the elastic member 240, which is conducive to the elastic member 240 to stretch and deform within a certain range, avoids the elastic member 240 from deviating and affecting the accurate pushing of the valve core 220, thereby avoiding the water leakage of the water outlet valve 200 due to the poor closing. Moreover, compared with installing the positioning member 250 on the valve body 210, installing the positioning member 250 on the filter screen 600 does not need to change the structure of the valve body 210, which is convenient for the machining of the valve body 210 and the assembly.

[0071] As an example, as shown in Figure 6 The positioning member 250 is a positioning block, the top end of the positioning block has a protruding part, the middle part of the filter screen 600 has a mounting hole, the protruding part is inserted into the mounting hole to realize the positioning of the positioning member 250. The positioning member 250 is convenient to assemble. Moreover, the filter screen 600 can be distributed with filter holes around the mounting hole, which is convenient for the liquid in the inner container 100 to flow into the water outlet valve 200 through the filter screen 600 from multiple directions, and the positioning member 250 does not interfere with the outflow of the liquid too much, ensuring the smooth outflow of the liquid in the inner container 100.

[0072] As an example, as shown in Figure 6 The elastic member 240 is a conical spring, the top end of the conical spring is sleeved on the outer periphery of the positioning member 250, and the bottom end of the conical spring is sleeved on the outer periphery of the valve core 220. Here, the elastic member 240 is a conical spring with a small top end and a large bottom end, so that the positioning member 250 has a relatively small volume, which can reduce the blocking degree of the positioning member 250 to the water flow, ensure the smooth outflow of the liquid in the inner container 100, and does not affect the limiting of the elastic member 240. Moreover, the bottom end of the elastic member 240 is sleeved on the outer periphery of the valve core 220, if the valve core 220 is lifted and moves upward, it can uniformly extrude the elastic member 240 in the circumferential direction, avoiding the deviation and compression of the elastic member 240. Similarly, the elastic member 240 can also uniformly press the valve core 220 in the circumferential direction, so that it is tightly attached to the valve sealing member 230, ensuring the sealing performance of the water outlet valve 200 when it is closed.

[0073] Of course, in other examples, the top end of the elastic member 240 can not be sleeved on the outer periphery of the positioning member 250, and the bottom end of the elastic member 240 can not be sleeved on the outer periphery of the valve core 220, for example, the top end of the elastic member 240 is pressed against the lower end face of the positioning member 250, and the bottom end of the elastic member 240 is pressed against the upper end face of the valve core 220, and the like, which are not listed here.

[0074] Further, in some embodiments, the connecting nut 300 is a metal nut, and the valve body 210 is a metal valve body.

[0075] The positioning ring and the valve body 210 in the related art are usually plastic parts, which are soaked in boiling water for a long time, and have the risk of aging and water leakage. In the embodiment, the connecting nut 300 and the valve body 210 are both made of metal material, which strengthens the stability of the overall structure. The connecting threads 211 on the connecting nut 300 and the valve body 210 will not be deformed in a high-temperature environment, which can effectively ensure the sealing of the connection between the two and avoid water leakage. In addition, metal materials are more hygienic and have a longer service life, which can effectively ensure the hygiene during use. In addition, metal materials have high strength and good toughness, and are not easy to be damaged after long-term frequent use, which can significantly prolong the service life of the product and reduce the frequency and cost of replacing the product for users.

[0076] For example, the valve body 210 is a stainless steel valve body, and the connecting nut 300 is a stainless steel nut.

[0077] Further, in some embodiments, as shown in Figure 6 The liner assembly further includes a gasket 400 surrounding the outer periphery of the water outlet valve 200 and clamped between the wall surface around the connecting nut 300 and the water outlet 111. In this way, the connecting nut 300 can be prevented from rubbing against the wall surface around the water outlet 111 during the process of screwing the connecting nut 300, and the wall surface around the water outlet 111 can be prevented from being worn. In addition, by providing the gasket 400, the connecting nut 300 can also be prevented from loosening.

[0078] Further, in some embodiments, as shown in Figure 6 The liner assembly further includes a gasket 400 surrounding the outer periphery of the water outlet valve 200 and clamped between the wall surface around the connecting nut 300 and the water outlet 111. In this way, the connecting nut 300 can be prevented from rubbing against the wall surface around the water outlet 111 during the process of screwing the connecting nut 300, and the wall surface around the water outlet 111 can be prevented from being worn. In addition, by providing the gasket 400, the connecting nut 300 can also be prevented from loosening.

[0079] For example, the outer periphery of the valve body 210 of the water outlet valve 200 has a mounting groove, and a part of the gasket 500 is embedded in the mounting groove and a part of the gasket 500 protrudes outward from the mounting groove. The design of the mounting groove can prevent the gasket 500 from moving around, and facilitate the gasket 500 to be quickly installed in place in the position aligned with the mounting groove.

[0080] As an example, the outer periphery of the valve body 210 of the water outlet valve 200 has a convex rib, and the sealing member 500 is a sealing ring, the inner side wall of which has a limiting groove into which the convex rib is inserted. The cooperation of the convex rib and the limiting groove can also avoid the sealing member 500 from moving around and facilitate the quick installation of the sealing member 500 to the position aligned with the convex rib.

[0081] Further, in some embodiments, as shown in Figure 6 Further, a portion of the bottom wall of the inner container 100 is concave downward to form a sunken platform 110, and the water outlet 111 is arranged on the sunken platform 110; the upper surface of the filter screen 600 is lower than or flush with the upper surface of the edge of the bottom wall of the inner container 100. Such a design facilitates the liquid in the inner container 100 to flow to the filter screen 600 at a low position and flow out through the water outlet 111. Moreover, the filter screen 600 does not protrude conspicuously, which facilitates the user to clean the inner container without being easily scratched by the filter screen 600.

[0082] Further, the filter screen 600 is arranged on the top of the valve body 210, and the filter screen 600 comprises a screen top wall 610 and a screen side wall 620, the screen top wall 610 is provided with a plurality of first filter holes 611, and the screen side wall 620 is provided with a plurality of second filter holes 621, the plurality of first filter holes 611 are communicated with the inner cavity of the valve body 210 through the opening of the top of the valve body 210, and the top of the outer side wall of the valve body 210 is provided with a plurality of through holes 213, and each second filter hole 621 is communicated with the inner cavity of the valve body 210 through one through hole 213.
