[0056] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Various examples are provided by way of explanation and not by way of limitation. In fact, those skilled in the art will recognize that modifications and variations can be made to the present application without departing from the scope or spirit thereof. For example, a feature shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment.

Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0058] The accompanying drawings illustrate one or more examples of this application. The detailed description uses numerical and alphabetic designations to refer to features in the drawings. Similar or analogous designations in the drawings and description have been used to refer to similar or analogous parts of this application. As used herein, the terms “first,” “second,” and “third,” etc., are used interchangeably to distinguish one component from another and are not intended to indicate the location or importance of individual components.

[0059] like Figures 1 to 3 As shown, according to an embodiment of this application, a beverage dispenser 10 is provided, which includes a housing 100, a housing 100 and an adapter assembly 501. A circuit board 401 and a pump 302 are disposed within the housing 100. A control circuit is arranged on the circuit board 401, and the pump 302 is electrically connected to the circuit board 401. In some embodiments, the circuit board 401 can be powered by an external power adapter, which directly powers the circuit board 401; alternatively, a battery 403 can be built into the dispenser, which is electrically connected to and powers the circuit board 401.

[0060] The adapter component 501 is frustum-shaped, taking a frustum of a cylinder as an example. The adapter component 501 has silicone sidewalls. Silicone is elastic, allowing for good sealing performance when the adapter component 501 is mated with the opening 601 of the container 60. Other elastic materials can also be used for the sidewalls of the adapter component 501; no specific limitations are imposed here. The radius of the first end of the adapter component 501 is smaller than the radius of the second end, making the axial section of the adapter component 501 trapezoidal. When the adapter component 501 is mated with the opening 601 of the container 60, the first end of the adapter component 501 is inserted into the opening 601 of the container 60. Because the adapter component 501 is frustum-shaped and the radius of the second end is larger than the radius of the first end, it is easier to insert the adapter component into the opening 601 of the container 60. Moreover, during the insertion process, the outer surface of the adapter component 501 gradually tightens until the sidewall of the adapter component 501 is tightly fitted with the inner wall of the opening 601. At this time, the opening 601 of container 60 is blocked by the adapter assembly 501 to seal container 60.

[0061] like Figure 5 and Figure 6 As shown, in some embodiments, the sidewall of the adapter 501 extends in a stepped manner from a first end to a second end, forming a plurality of annular structures, with the radius of the annular structures increasing sequentially from the first end to the second end. Each annular structure has a first end and a second end in an axial direction, wherein the first end of the annular structure faces the first end of the adapter 501, and the second end of the annular structure faces the second end of the adapter 501. The radius of the first end of the annular structure is equal to or less than the radius of the second end, and the radius of the second end of the annular structure is less than the radius of the first end of the annular structure adjacent to the second end. Figure 8 As shown, taking an adjacent first ring structure 501a and second ring structure 501b among several ring structures as an example, the radius of the second end of the first ring structure 501a is smaller than the radius of the first end of the second ring structure 501b. The radius of the first end of the first ring structure 501a is slightly smaller than the radius of the second end, and the radius of the first end of the second ring structure 501b is also slightly smaller than the radius of the second end. The stepped structure in this embodiment serves to... Figure 8 For the non-stepped sidewalls formed by the auxiliary line L1, the inclination angle of each annular structure's sidewall is relatively small or 0° (the inclination angle is 0° when the radius of the first end of the annular structure is equal to the radius of the second end), resulting in a relatively even fit between the sidewall of the annular structure and the inner wall of the container 60's snap-fit. This achieves a better sealing effect and prevents the adapter component 501 from becoming loose due to uneven stress on the sidewalls.

[0062] like Figure 8As shown, in some embodiments, a connecting ring 501c is provided between two adjacent annular structures, and the two ends of the connecting ring 501c share corresponding ends with the annular structures on both sides. The purpose is to guide the opening 601 of the container 60 to transition from one annular structure to another, and relatively reduce the resistance encountered during the transition.

[0063] like Figures 6 to 7 As shown, in some embodiments, the adapter assembly 501 includes an adapter 5011, with a rubber sleeve 5013 fitted onto the outer side of the adapter 5011. The rubber sleeve 5013 is made of silicone, but other elastic materials can also be used; no specific limitation is made here. The purpose of this design is that different rubber sleeves 5013 can be selected for the same adapter 5011 according to different needs, so that the adapter assembly 501 has better adaptability. The rubber sleeve 5013 can be directly molded onto the outer side of the adapter 5011; or the rubber sleeve 5013 can be fitted onto the outer side of the adapter 5011 and fixed to each other; or the rubber sleeve 5013 can be detachably fitted onto the outer side of the adapter 5011; no specific limitation is made here. Of course, in some embodiments, the sidewall of the silicone sleeve 5013 has the stepped structure described in the above embodiments.

[0064] like Figures 2 to 4 , Figure 10 , Figure 14As shown, in some embodiments, the second end of the adapter component 501 is installed at the bottom of the housing 100 of the distributor 10. The adapter component 501 is provided with a first interface 502 and a second interface 503. Both the first interface 502 and the second interface 503 are provided with channels penetrating the first end and the second end of the adapter component 501. The first interface 502 and the second interface 503 are both in the same direction as the adapter component 501. The second end of the first interface 502 is connected to the inlet of the pump 302 through a first pipe 301. The housing 100 is provided with an outlet pipe 202, which is connected to the outlet 2021 of the pump 302 through a second pipe 303. The housing 100 is provided with a one-way air inlet valve 305, which is connected to the second end of the second interface 503 through a third pipe 304. The first end of the first interface 502 is connected to a fourth pipe 504, which extends to the bottom of the container 60. In use, the pump 302 can be selectively activated via the control circuit on the circuit board 401, allowing the liquid in the container 60 to flow out from the outlet 2021 of the outlet pipe 202 along the fourth pipe 504, the first interface 502, the first pipe 301, the pump 302, and the second pipe 303. Simultaneously, the one-way air inlet valve 305 is open, allowing air to enter the container 60 along the third pipe 304 and the second interface 503 to regulate the pressure difference between the inside and outside of the container 60. Furthermore, when the one-way air inlet valve 305 is open, it prevents a vacuum from forming inside the container 60 due to the removal of the beverage, thus avoiding deformation, tilting, or tipping of the container 60. When the one-way air inlet valve 305 is closed, it prevents air from entering the container 60 through the third pipe, further extending the shelf life of the beverage.

[0065] In the above embodiments, the one-way air intake valve 305 can be a one-way valve with a physical structure; or an electronic one-way valve with an electronic structure. The electronic one-way valve is electrically connected to the circuit board 401, and the working state of the electronic one-way valve is synchronized with that of the pump 302.

[0066] For some deformable containers, in some embodiments, the adapter component 501 may remove the second interface 503, retaining only the first interface 502. When the pump 302 draws out the beverage, the deformable container deforms as the amount of beverage inside decreases to balance the pressure difference between the inside and outside of the container. Examples include some soft or stretchable containers.

[0067] like Figure 4 , Figure 7 and Figure 10As shown, in some embodiments, the housing 100 includes an upper housing 101 and a lower housing 102, which can be selectively fastened together. The bottom of the lower housing 102 has a mounting opening 201, the shape of which is the same as and compatible with the cross-sectional shape of the adapter assembly 501. The adapter 5011 has a first end and a second end in the same direction as the adapter assembly 501. The second end of the adapter 5011 has a first protruding edge 5012 extending radially outward. The rubber sleeve 5013 has a first end and a second end in the same direction as the adapter assembly 501. The second end of the rubber sleeve 5013 has a second protruding edge 5014 extending radially outward. The inner diameter of the mounting opening 201 is larger than the outer diameter of the second end of the adapter assembly 501 but smaller than the outer diameters of the first protruding edge 5012 and the second protruding edge 5014. After the adapter assembly 501 is assembled with the lower housing 102, the second protruding edge 5014 of the rubber sleeve 5013 is sandwiched between the peripheral wall of the assembly port 201 and the first protruding edge 5012. This serves to secure the rubber sleeve 5013 to the housing 100, and the rubber sleeve 5013 also forms a sealing ring around the assembly port 201 to prevent liquid from entering the housing 100. In some embodiments, the outer side of the first protruding edge 5012 of the adapter 5011 is provided with a plurality of lugs 5018, each lug having a through hole. A screw-like connector can be inserted into the through hole to secure the adapter 5011 to the lower housing 102.

[0068] In some embodiments, the peripheral wall of the assembly port 201 is provided with a first convex ring 2011 extending into the inner side of the lower housing 102, and the second convex edge 5014 of the rubber sleeve 5013 is provided with a first annular groove 5015 on the side facing the first end of the rubber sleeve 5013. The first annular groove 5015 and the first convex ring 2011 are adapted to each other to improve the sealing effect of the assembly port 201. In a further embodiment, a second convex ring 2012 with the same center is provided inside the lower housing 102 and outside the first convex ring 2011. The first convex ring 2011 and the second convex ring 2012 form a second annular groove 2013. The outer wall of the second convex edge 5014 and the inner wall of the first annular groove 5015 form a third convex ring 5016. The third convex ring 5016 and the second annular groove 2013 are adapted to each other to further improve the sealing effect of the assembly port 201.

[0069] like Figure 6 and Figure 7 As shown, in some embodiments, the first end of the sleeve 5013 has an inwardly extending inner folded edge 5017, so that the first end of the sleeve 5013 can cover at least a portion of the end face of the first end of the adapter 5011. In another embodiment, the inner folded edge 5017 extends inward to form a surface. However, this surface does not affect the function and role of the first interface 502 and the second interface 503.

[0070] In some embodiments, the housing 100 is further provided with a power switch, and a first switch 404 is electrically connected to the circuit board 401. The first switch 404 is used to control the power-on state of the circuit in the distributor 10. The type and location of the first switch 404 are not specifically limited here.

[0071] In some embodiments, the housing 100 is further provided with a power interface 405, which is electrically connected to the circuit board 401. An external power adapter can be plugged into the power interface 405 to charge the battery 403 in the distributor 10. The type and location of the power interface 405 are not specifically limited here.

[0072] like Figure 12 and Figure 13 As shown, in some embodiments, the housing 100 is also provided with a second switch, which is electrically connected to the circuit board 401. The second switch is used to control the start and stop of the pump 302. Here, the second switch is exemplified by a toggle switch 402, which has a lever 4021 that triggers the switching of the circuit. Correspondingly, the housing 100 is provided with a flip-up push plate 204, which is rotatably connected to the housing 100 via a rotating shaft 2041. The first end of the push plate 204 extends into the housing 100, and the second end remains outside the housing 100. The rotating shaft 2041 is positioned between the first and second ends. Flipping the second end of the push plate 204 causes the first end to rotate in the same direction, so that the first end touches the lever 4021, thereby changing the on / off state of the circuit. The outlet 2021 of the water outlet pipe 202 is located on the same side of the push plate 204. For example, as in 12, the lever 4021 is in the unfolded state, at which time the circuit is in the open state. Figure 13 In the middle, flipping the second end of the push plate 204 causes its first end to touch and push the lever 4021, thus completing the circuit and starting the pump 302. During use, as... Figures 15-16 As shown, the cup 70 can be used to apply force to the push plate 204. After the push plate 204 touches the lever 4021, the pump 302 starts to work, and the liquid in the container 60 can flow directly into the cup 70 from the outlet 2021 of the outlet pipe 202.

[0073] In some embodiments, a spring 203 is installed inside the housing 100. One end of the spring 203 acts on the housing 100, and the other end of the spring 203 acts on the first end of the push plate 204. When the push plate 204 is flipped under the action of an external force, and the circuit changes from an open circuit to a closed circuit, the shape of the spring 203 is changed. When the external force on the push plate 204 is removed, the deformation force of the spring 203 acts on the first end of the push plate 204, causing the push plate 204 to flip in the opposite direction. At the same time, the circuit changes from a closed circuit to an open circuit.

[0074] In some embodiments, the first end of the push plate 204 is provided with a groove 2042. Flipping the push plate 204 can cause the outlet 2021 of the water pipe 202 to be inserted into the groove 2042 and locked together to prevent the outlet 2021 from being contaminated.

[0075] The above descriptions are merely examples of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
