[0002] Beverage machines include milk tea machines, juice machines, beverage machines, etc., which are used in the food field. Beverage machines usually include a beverage container part and a beverage discharge part. Water outlet valves need to be set at the container and the discharge position to realize the discharge of beverages. In actual application, since beverages contain a lot of sugar, due to food safety requirements, the parts in the beverage machine that come into contact with the beverages need to be cleaned frequently.

[0003] In actual application, the existing water outlet valve, such as patent CN201827456U, a barrel-type manual water gun self-locking one-way water outlet valve, includes a valve body, a valve core and a top column. A through hole is arranged on the valve core and a spring is installed at the end to resist against the valve body. The flow and sealing between the through hole and the valve body are realized by the thrust of the top column on the valve core and the reaction force of the spring. The top column of the water outlet valve is popped out by the reaction force of the spring. If the reaction force of the spring is large or the valve body is not long enough, the top column may fall off easily. In addition, the inside and outside of the valve core of the device need to be in contact with the internal liquid. If the water outlet valve is applied to edible machinery such as milk tea machines, there are many blind spots in the valve core for cleaning, and complete cleaning cannot be achieved. Therefore, it cannot be applied. Utility Model Content

[0034] Example 1

[0035] Reference Figures 1 to 3, this embodiment provides a water outlet device for a beverage machine, including a container 1, a valve body 2 and a joint 3. The container 1 is filled with beverage liquid, the valve body 2 is installed at the lower part of the container 1, and the joint 3 is connected to the valve body 2. When the valve body 2 is opened, the liquid in the container 1 flows from the valve body 2 to the joint 3, wherein: a connecting sleeve 11 is installed at the connection position between the container 1 and the valve body 2, the connecting sleeve 11 is a through-hole structure, and the connecting sleeve 11 provides an installation position for the joint 3. In the water outlet valve, the valve body 2 includes a valve core 21, the valve core 21 is installed in the connecting sleeve 11 and has a length greater than the length of the connecting sleeve 11, and the top area of ​​the valve core 21 is greater than the through-hole aperture of the connecting sleeve 11 to ensure that the valve The core 21 can seal the through hole of the connecting sleeve 11. The joint 3 is put on the outside of the connecting sleeve 11. A through pipe for liquid circulation is arranged inside the joint 3. When the joint 3 is installed, the through pipe abuts against the valve core 21 to ensure that the liquid flowing out of the valve core 21 can completely enter the through pipe. A sealing connection structure is arranged at the connection position of the connecting sleeve 11, the valve core 21 and the joint 3. The sealing connection structure includes a sealing strip 4 and a retaining structure. The sealing strip 4 is arranged on the outer wall of the connecting sleeve 11 for fixing the joint 3 and the connecting sleeve 11. The retaining structure is arranged on the valve core 21 for ensuring that when the valve core 21 is opened, the valve core 21 will not fall off from the drain valve.

[0036] Furthermore, referring to Figure 1 The valve core 21 is divided into two parts: a top sealing structure and a bottom cylindrical structure. The cross-section of the top sealing structure is larger than that of the bottom cylindrical structure. The top sealing structure is used to seal the container. The side wall of the bottom cylindrical structure is provided with a plurality of concave surfaces, which extend from the upper end to the end of the bottom cylindrical structure. When the container 1 is connected to the joint 3, the through pipe in the joint 3 abuts against the valve core 21 to push the valve core 21 out, or when the valve core 21 is opened by other means, the valve core 21 moves up, and the concave surface on the bottom cylindrical structure is exposed. The concave surface and the inner wall of the connecting sleeve 11 form a channel for the liquid in the container 1 to flow out.

[0037] In this embodiment, the locking structure is a magnetic attraction device, which is specifically represented as follows: Figure 1, a magnet 5 is installed in the top sealing structure of the valve core 21, and a magnet 5 is also arranged at the bottom of the connection between the connecting sleeve 11 and the container 1 and at the top of the joint 3 where the magnet 5 on the top of the valve core 21 matches, and the installation position of the magnet 5 is close to the outer wall of the device. When the beverage machine is sealed, the valve core 21 is inserted into the connecting sleeve 11, and the top sealing structure of the valve core 21 contacts the inner wall of the bottom surface of the container 1, so the magnet 5 in the top sealing structure and the magnet 5 at the bottom of the container 1 attract each other to ensure the sealing of the container 1; when the beverage machine is used, the joint 3 is sleeved on the connecting sleeve 11, and the container 1 filled with liquid is pressed down by its own gravity. When the container 1 falls, the position of the joint 3 rises relative to the container 1, Since the length of the valve core 21 is greater than the connecting sleeve 11, the through pipe in the joint 3 supports the valve core 21. As the position of the joint 3 rises, the position of the valve core 21 also gradually rises, that is, the water inlet valve is opened, exposing the concave surface on the bottom cylindrical structure, so that the liquid flows from the container 1 into the through pipe of the joint 3. When the joint 3 rises to the bottom surface of the container 1, the top of the joint 3 is connected with the magnet 5 at the bottom of the container 1, which improves the stability of the connection of the joint 3 on the one hand, and increases the number of magnets 5 under the valve core 21 on the other hand, thereby improving the attraction of the magnets 5 below. Therefore, when the position of the valve core 21 moves up, the joint 3 and the magnets 5 at the bottom of the container 1 jointly attract the magnet 5 on the valve core 21 to prevent the valve core 21 from detaching.

[0038] It should be noted that the magnetic force between the magnets 5 is smaller than the dead weight of the container 1 and the valve body 2. The valve body 2 is installed on the container 1. When the container 1 is connected to the joint 3, the magnets 5 installed on the joint 3 and the container 1 attract each other. The magnetic force between the magnets 5 is smaller than the dead weight of the container 1 and the valve body 2. On the one hand, when the container 1 is connected to the joint 3, it is convenient to manually adjust the position, and the mass of the container 1 can be used to press down to reduce costs. In addition, it is also convenient to disassemble the joint 3.

[0039] Furthermore, a boss is provided on the inner wall of the through tube in the connector 3, and the boss is used to abut the end of the valve core 21. When the connector 3 is connected to the connecting sleeve 11, the boss abuts the valve core 21 to move upward. When the top of the connector 3 reaches the bottom of the container 1, the boss abuts the valve core 21 to the bottom surface of the connecting sleeve 11, so that the boss is communicated with the connecting sleeve 11. The boss structure is arranged around the inner wall of the through tube, and a through hole is formed in the middle. Therefore, the through hole in the connecting sleeve 11 can be communicated with the through hole in the middle of the boss. In order to ensure that the liquid flows down smoothly, the radius of the through hole in the middle of the boss needs to be larger than the distance between the most concave point of the concave surface on the cylindrical structure at the bottom of the valve core 21 and the center line of the valve core 21.

[0040] It should be noted that a circle of raised structure is provided on the bottom surface where the connecting sleeve 11 is connected to the container 1, which is used to wrap the magnet 5. The outer ring wrapping the magnet 5 on the valve core 21, the bottom surface of the container 1 and the top of the joint 3 can be made of edible flexible material, which can increase the sealing when closed. In addition, it can also be made of the same food-grade metal material as the mounting structure to ensure the integrity of the device.

[0041] Furthermore, the three magnets 5 are installed around the columnar structure at the bottom of the valve core 21, which can ensure the mutual contact surfaces between the magnets 5 and enhance the attraction.

[0042] In this embodiment, the connecting portion between the connecting sleeve 11 and the inner wall of the container 1 is a curved surface structure extending outward, which enlarges the connecting port between the connecting sleeve 11 and the inner wall of the container 1 and facilitates the downward flow of the liquid in the container 1.

[0043] In this embodiment, a sealing strip is provided at the connection position between the top sealing structure and the bottom cylindrical structure in the valve core 21, that is, above the concave surface of the bottom cylindrical structure, to ensure the sealing between the container 1 and the channel 11 when the valve core 21 is closed.

[0044] It should be noted that the sealing strip can be set in two forms. Form one is to directly mold silicone on the valve core 21 to form the two into one, without gaps, which is easy to clean; form two is that the sealing strip is a separate part, which is put on the valve core 21, and the sealing strip can be replaced regularly.

[0045] The working principle of the water outlet valve of the beverage machine in this embodiment is as follows: before the beverage machine is used, the valve core 21 is inserted into the connecting sleeve 11, and the top sealing structure of the valve core 21 covers the connecting sleeve 11 to achieve closure. The valve core 21 and the magnet at the bottom of the container 1 attract each other to achieve the fixation of the valve core 21, and a sealing strip is provided at the connection position between the top sealing structure of the valve core 21 and the bottom cylindrical structure to further improve the sealing performance; when the beverage machine starts to be used, the joint 3 is put on the connecting sleeve 11 from the bottom of the container 1, and the container 1 is pressed down by the weight of the container 1 and the liquid inside or manually, so that the top of the joint 3 is pressed against the bottom of the container 1, so that the joint 3 is completely covered As for the connecting sleeve 11, a sealing strip is installed at the bottom of the connecting sleeve 11, which further ensures the stability of the connection between the joint 3 and the connecting sleeve 11. When the container 1 falls, the boss in the through pipe in the joint 3 presses against the valve core 21 and moves upward, so that the valve core 21 and the container 1 are opened. When the joint 3 reaches the bottom of the container 1, the boss fits with the bottom of the connecting sleeve 11. In addition, since a concave surface is provided on the cylindrical structure at the bottom of the valve core 21, and the most concave part of the concave surface is lower than the edge of the boss, the through hole in the boss can be connected with the connecting sleeve 11, so that the liquid in the container 1 flows into the joint through pipe from the channel between the connecting sleeve 11 and the concave surface of the valve core.

[0046] Example 2

[0047] In this embodiment, the difference from the embodiment 1 is that the locking structure in the sealed connection structure is different. Figure 4 The positioning structure is a conical structure, wherein the bottom of the conical structure cooperates with the concave surface on the side wall of the bottom cylindrical structure of the valve core 21 to set a through hole, the conical structure is arranged at the tail end of the bottom cylindrical structure of the valve core 21, and the upper and lower surface diameters of the conical structure are both larger than the diameter of the bottom cylindrical structure of the valve core 21, and the valve core 21 and the conical structure are both set to flexible materials, the flexible material has greater elasticity, and the elastic characteristics of the flexible material can be used to ensure the sealing between the valve core 21 and the connecting sleeve 11.

[0048] In this embodiment, the connecting sleeve 11 is evenly divided into two sections, the diameter of the upper section matches the valve core 21, the diameter of the lower section matches the diameter of the larger surface of the conical structure, and the sealing strip 4 on the outer wall of the connecting sleeve 11 is arranged on the lower section with a larger diameter.

[0049] When in use, since the valve core 21 and the tapered structure are both made of flexible materials, when the valve core 21 is extended into the connecting sleeve 11, the elastic deformation of the flexible material completes the positioning and sealing of the valve core 21; when the liquid in the container 1 needs to be discharged, the connector 3 is put on the connecting sleeve 11, and the connecting sleeve 11 is pressed down by the gravity of the container 1 and the internal solution or the pressure applied manually, as in Example 1. Since the valve core 21 is longer than the connecting sleeve 11, the through pipe of the connector 3 can resist the tapered structure and push the valve core 21 upward. When the joint 3 is pushed upward, the joint 3 is sleeved on the connecting sleeve 11, and the inner wall of the joint 3 is connected with the outer wall of the connecting sleeve 11. The sealing strip on the outer wall of the connecting sleeve 11 can realize the sealing of the joint 3 and the connecting sleeve 11. At the same time, the upper part of the valve core 21 is opened, and the liquid flows into the channel between the concave surface of the valve core 21 and the connecting sleeve 11. Since the bottom of the conical structure is connected with the concave surface, the liquid can flow from the bottom of the conical structure into the through pipe in the joint 3, so as to realize the discharge of the liquid in the container 1.

[0050] It should be noted that, refer to Figure 5 The conical structure of the head of the valve core 21 can also be a claw type.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
