[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Embodiment 1

[0033] See also Figures 1 to 3 As shown, the utility model is a spiral sealing device for a tea brewing discharge port of a tea drinking machine, comprising a temporary storage tube 1 and a blocking mechanism located in the temporary storage tube 1. The lower end of the temporary storage tube 1 is a constricted structure and has a discharge port 101, so that the temporary storage tube 1 is funnel-shaped as a whole. The outer wall of the temporary storage tube 1 can be connected to a support portion with a cylindrical structure for installing a box body for storing tea leaves.

[0034] like Figure 4 As shown, the blocking mechanism includes an outer cylinder 2, a movable cylinder 3 sleeved in the outer cylinder 2, and a motor 4 fixedly connected to the outer cylinder 2. Among them, four BOSS columns 102 are fixedly connected in the temporary storage cylinder 1, and the outer wall of the outer cylinder 2 is provided with connecting ears 202 corresponding to the BOSS columns 102, which are used to connect the connecting ears 202 with the BOSS columns 102 by screws to achieve connection and fixation to the outer cylinder 2.

[0035] like Figures 5 to 8 As shown, the inner wall of the outer cylinder body 2 is provided with two or more axially arranged slide grooves 201, the outer wall of the movable cylinder 3 is provided with a directional strip 301 matched with the slide groove 201, and the inner wall of the movable cylinder 3 is provided with an internal thread 302. The output shaft of the motor 4 is connected with a driving column 401, and the driving column 401 is provided with an external thread, and the thread is matched with the internal thread 302 on the inner wall of the movable cylinder 3, so as to drive the driving column 401 to rotate through the motor 4, so as to realize the axial movement of the movable cylinder 3.

[0036] When it is necessary to brew tea, the motor 4 drives the driving column 401 to rotate, and the threaded connection is used to make the movable cylinder 3 move axially upward. When the lower end of the movable cylinder 3 is located above the discharge port 101, the discharge port 101 is opened, and the tea leaves in the temporary storage cylinder 1 automatically fall into the teacup for brewing tea. Among them, the lower end of the directional strip 301 is fixedly connected to the limiting protrusion 304, and the lower end surface of the outer cylinder 2 is provided with a notch 204 that cooperates with the limiting protrusion 304. When the movable cylinder 3 rises to the limiting protrusion 304 and is stuck in the notch 204, the movable cylinder 3 cannot rise any further, so that the upward movement position of the movable cylinder 3 is limited by the limiting protrusion 304.

[0037] After the tea leaves are put in, the motor 4 drives the driving column 401 to rotate in the opposite direction, so that the movable cylinder 3 moves axially downward, and the lower end of the movable cylinder 3 is inserted into the discharge port 101, and the lower end of the movable cylinder 3 is used to seal the discharge port 101, thereby preventing water vapor from entering the temporary storage cylinder 1.

[0038] Among them, an annular groove is opened on the outer wall of the lower end of the movable cylinder 3, and a sealing ring 303 is sleeved thereon. When the discharge port 101 is sealed through the lower end of the movable cylinder 3, the sealing ring 303 cooperates with the inner wall of the discharge port 101 to achieve sealing. Adding the sealing ring 303 is beneficial to improving the sealing performance and ensuring the reliability of the sealing, thereby effectively meeting and adapting to the moisture-proof requirements of the tea drinking machine in commercial scenarios.

[0039] Embodiment 2

[0040] like Figure 8 and 9 As shown, on the basis of embodiment 1, an inner cylinder 203 is arranged in the outer cylinder 2, and the upper end of the inner cylinder 203 is open, and the lower end has a bottom wall structure, the outer cylinder 2 and the inner cylinder 203 are an integrated structure, and the bottom wall of the inner cylinder 203 is provided with a connecting hole and a through hole, the motor 4 is installed in the inner cylinder 203, and the motor 4 is connected and fixed by passing screws through the connecting hole, and the output shaft of the motor 4 passes through the bottom wall of the inner cylinder 203 through the through hole, so that the output shaft of the motor 4 is connected to the driving column 401, and the motor 4 is installed in the inner cylinder 203 in the outer cylinder 2, so that the overall structure is more compact, which is conducive to reducing the overall volume.

[0041] Embodiment 3

[0042] like Figure 1 , 3 As shown in FIG. 4 , four partitions 103 are radially arranged inside the temporary storage tube 1, and the four partitions 103 are evenly distributed along the circumference of the discharge port 101, and are used to divide the interior of the temporary storage tube 1 into four fan-shaped chambers 104 through the four partitions 103. The fan-shaped chambers 104 correspond to the storage cavities of tea leaves one by one to avoid the mixing of different types of tea leaves.

[0043] At the same time, the partition 103 is integrally formed with the BOSS column 102. The partition 103 and the BOSS column 102 installed on the outer cylinder 2 are set as an integrated structure, which not only improves the overall structural strength, but also avoids the BOSS column 102 being located in the fan-shaped chamber 104. The BOSS column 102 is easily blocked and causes the tea leaves to be retained in the fan-shaped chamber 104, thereby helping to improve the overall reliability of use.
