A spout structure for hot and cold beverage dispensers

Abstract

This utility model belongs to the technical field of drinking water equipment, and provides a water outlet structure for a hot and cold beverage machine, including a sealed cylinder, a connecting pipe, and a water outlet pipe. The sealed cylinder is located at the top of the connecting pipe. The connecting pipe has a feed inlet and an air inlet on its side wall, with the air inlet located below the feed inlet and gradually sloping upwards from the inside to the outside. The top of the water outlet pipe is coaxially connected to the bottom of the connecting pipe. With this water outlet structure, after water flow stops, the air inlet on the side wall of the connecting pipe allows air to enter, breaking the siphon effect or vacuum state inside the pipe. After air enters, the liquid remaining on the inner wall of the water outlet is no longer subject to suction and will automatically drip downwards into the water receiving container due to gravity. This effectively reduces dirt and related hygiene problems caused by dripping from the water outlet, ensuring the food hygiene and safety of the hot and cold beverage machine. The gradually upward sloping air inlet from the inside to the outside prevents liquid from entering and remaining inside the air inlet, ensuring the unobstructed flow of air.

[0049] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0050] This embodiment provides a water outlet structure for a hot and cold beverage machine, including a sealed cylinder 1, a connecting pipe 2, and a water outlet pipe 3.

[0051] The closed cylinder 1 is set at the top of the connecting pipe 2, and the diameter of the closed cylinder 1 is larger than the outer diameter of the connecting pipe 2;

[0052] For example, see Figure 1-2 The closed cylinder 1 is coaxial with the connecting pipe 2. The large-diameter end of the frustum 6 is coaxially fixed with the bottom end of the closed cylinder 1, and the small-diameter end of the frustum 6 is coaxially fixed with the top end of the connecting pipe 2, so that the top end of the connecting pipe 2 is closed.

[0053] The side wall of the connecting pipe 2 is provided with a feed inlet 4 and an air inlet 5. The air inlet 5 is located below the feed inlet 4 and gradually slopes upward from the inside to the outside.

[0054] For example, see Figure 1-2 The connecting pipe 2 has two inlets 4 at the top of its side wall, which are used to allow beverages to enter the connecting pipe 2. The connecting pipe 2 also has an air inlet 5 at the bottom of its side wall, which is used to allow gas to enter.

[0055] The top end of the water outlet pipe 3 is coaxially connected to the bottom end of the connecting pipe 2, and the outer diameter of the water outlet pipe 3 is smaller than the outer diameter of the connecting pipe 2.

[0056] For example, see Figure 1-2 The inner diameter of the outlet pipe 3 is the same as that of the connecting pipe 2, and the outlet pipe 3 and the connecting pipe 2 together form a continuous channel. The outer diameter of the outlet pipe 3 is smaller than that of the connecting pipe 2, together forming a stepped pipe.

[0057] Based on the above, the water outlet structure provided in this embodiment allows air to enter the interior through the air inlet 5 on the side wall of the connecting pipe 2 after water flow stops, breaking the siphon effect or vacuum state inside the pipe. After air enters, the liquid remaining on the inner walls of the connecting pipe 2 and the water outlet pipe 3 is no longer subject to suction and will automatically drip downwards into the water container due to gravity. This effectively reduces dirt and related hygiene problems caused by dripping from the water outlet, ensuring the food hygiene and safety of the hot and cold beverage machine. Furthermore, the air inlet 5 gradually slopes upwards from the inside out, preventing liquid from entering and remaining inside the air inlet 5, thus ensuring the unobstructed flow of the air inlet 5.

[0058] Based on the above technical solution, in the technical solution provided in this embodiment, the inner diameter of the air inlet 5 gradually increases from the inside to the outside. This facilitates the entry of gas and also facilitates cleaning of the air inlet 5 from the outside, such as rinsing with water or cleaning with a brush.

[0059] The water outlet structure provided in this embodiment also includes a material bucket 7 and a guide tube 8. The bottom end of the material bucket 7 is provided with a water outlet 9, and the top end of the guide tube 8 is aligned and connected with the water outlet 9.

[0060] The closed cylinder 1 is located inside the material barrel 7, and the connecting pipe 2 is slidably sleeved inside the guide pipe 8. The connection pipe 2 and the guide pipe 8 are sealed.

[0061] For example, see Figure 3-5 A water outlet 9 is provided on the bottom plate on the left side of the material bucket 7. A guide tube 8 is fixedly provided at the bottom of the material bucket 7. The guide tube 8 is arranged vertically, and the top of the guide tube 8 is aligned and connected with the water outlet 9. The closed cylinder 1 is located inside the material bucket 7. The connecting pipe 2 is adapted to the guide tube 8. The connecting pipe 2 can slide up and down inside the guide tube 8, and the connecting pipe 2 passes through the guide tube 8.

[0062] Without external force, due to the gravity of the closed cylinder 1, the connecting pipe 2 can slide downwards inside the guide pipe 8 until the bottom of the frustum 6 contacts the outlet 9. At this time, the inlet 4 is located inside the guide pipe 8, and the beverage in the container 7 cannot enter the connecting pipe 2 through the inlet 4. At the same time, the connection pipe 2 and the guide pipe 8 are sealed, so that the beverage in the container 7 cannot flow out from the gap between the connecting pipe 2 and the guide pipe 8, that is, the outlet 9 is in a closed state.

[0063] When water is needed, the spout can be raised to a certain height manually or mechanically, i.e., the connecting pipe 2 moves upward a certain distance, exposing the inlet 4 above the outlet 9. At this time, the beverage in the container 7 can enter the connecting pipe 2 through the inlet 4, then flow out through the bottom of the outlet pipe 3, and finally enter the receiving container. When the spout is released, due to the gravity of the sealed cylinder 1, the connecting pipe 2 can slide downward within the guide pipe 8 until the bottom of the frustum 6 touches the outlet 9 again, thus sealing the outlet 9. At this time, the air inlet 5 on the side wall of the connecting pipe 2 is exposed outside the guide pipe 8, and air can enter the interior of the connecting pipe 2 through the air inlet 5, breaking any possible siphon effect or vacuum state. After the air enters, the liquid remaining on the inner wall of the connecting pipe 2 and the outlet pipe 3 is no longer subject to suction and will automatically drip downward into the receiving container due to gravity.

[0064] Among them, the inner diameter of the outlet 9 gradually decreases from top to bottom;

[0065] A buffer ring 10 is fitted on the outside of the connecting pipe 2, and the buffer ring 10 is located inside the water outlet 9;

[0066] For example, see Figure 4The outlet 9 gradually narrows from top to bottom, which serves two purposes: firstly, it guides the flow; secondly, when the bottom of the truncated cone 6 comes into contact with the outlet 9, the buffer ring 10 can be clamped between the truncated cone 6 and the outlet 9, thereby improving the seal between them. Simultaneously, the buffer ring 10 also acts as a shock absorber, preventing rigid collisions between the truncated cone 6 and the outlet 9.

[0067] In the technical solution provided in this embodiment, the bottom end of the material bucket 7 is provided with a mounting frame 11, and an L-shaped switch is hinged on the mounting frame 11. The L-shaped switch includes a horizontal plate 12 and a vertical plate 13. The horizontal plate 12 is provided with a through hole 14, and the water outlet pipe 3 is inserted into the through hole 14.

[0068] For example, see Figure 3-5 A mounting bracket 11 is installed at the bottom of the material tank 7. The guide tube 8 is located inside the mounting bracket 11. The top of the vertical plate 13 is fixed to the right end of the horizontal plate 12. The right end of the horizontal plate 12 is hinged to the mounting bracket 11. A through hole 14 is opened in the middle area of ​​the horizontal plate 12. The through hole 14 is adapted to the water outlet pipe 3, so that the water outlet pipe 3 can be inserted into the through hole 14, but the connecting pipe 2 cannot pass through the through hole 14. In this way, by pressing the vertical plate 13, the vertical plate 13 and the horizontal plate 12 rotate clockwise. At this time, the horizontal plate 12 supports and lifts the connecting pipe 2, and lifts the connecting pipe 2 a certain distance, so that the beverage in the material tank 7 can be discharged.

[0069] In the technical solution provided in this embodiment, an embedded annular groove 15 is provided on the side wall of the connecting pipe 2, the air inlet 5 is located in the annular groove 15, and an adjusting ring 16 is rotatably sleeved on the outside of the annular groove 15. The adjusting ring 16 is provided with a connecting hole 17 corresponding to the air inlet 5.

[0070] For example, see Figure 6-8 An embedded annular groove 15 is coaxially formed on the side wall of the connecting pipe 2. An adjusting ring 16 is rotatably fitted around the outside of the annular groove 15. The adjusting ring 16 is adapted to the annular groove 15, and the inner wall of the adjusting ring 16 abuts against the annular groove 15. A connecting hole 17 is provided through the side wall of the adjusting ring 16. By rotating the adjusting ring 16, the air inlet 5 is blocked by the adjusting ring 16, thus closing the air inlet 5. In this way, when it is not needed (such as when the business is closed at night), the air inlet 5 can be closed by rotating the adjusting ring 16. When it is needed, the air inlet 5 can be opened by rotating the adjusting ring 16 again so that the connecting hole 17 is aligned with the air inlet 5.

[0071] Secondly, the bottom of the water outlet pipe 3 can be plugged with a stopper. By installing the stopper, the bottom of the water outlet pipe 3 can be sealed. Combined with the sealing of the air inlet 5, the water outlet can be completely sealed, preventing small insects and other debris from entering the water outlet and contaminating it.

[0072] Furthermore, multiple air inlets 5 are provided circumferentially on the side wall of the connecting pipe 2. All the air inlets 5 are located in the annular groove 15, and the inner diameter of the air inlets 5 at different positions is different.

[0073] By rotating the adjusting ring 16, the connecting hole 17 can be aligned with the air inlet 5 with different inner diameters, thus adjusting the inner diameter of the air inlet 5, which is suitable for slurries of different concentrations.
