[0030] Reference Figure 3-Figure 5 A water outlet control mechanism for a tea maker is provided inside the tea maker, comprising a water storage tank 1, a valve stem assembly, a drive assembly 500 and a control unit, wherein:

[0031] A water storage tank 1 is arranged inside the tea maker, a water inlet of the water storage tank 1 is connected to a water outlet of an instant heating module in the tea maker, a water inlet of the instant heating module is connected to a water outlet of a cold water tank or an external water source, cold water can be heated by the instant heating module, and the heated water can be stored in the water storage tank 1;

[0032] The valve stem assembly includes an elastic pressing assembly 2 and a leak-proof valve stem 3. The elastic pressing assembly 2 is mounted on the water storage tank 1. The leak-proof valve stem 3 is mounted on the bottom of the elastic pressing assembly 2. The leak-proof valve stem 3 is movably arranged inside the water storage tank 1. More specifically, the leak-proof valve stem 3 is movably inserted into the water storage tank 1 and can be moved in the up and down directions.

[0033] One end of the stop-leak valve stem 3 is used to seal the water outlet 4 of the water storage tank 1, and the elastic pressing component 2 is connected to the stop-leak valve stem 3, and the elastic pressing component 2 always has a tendency to drive the stop-leak valve stem 3 away from the water outlet 4;

[0034] The driving assembly 500 includes a motor 5 and a cam 6 connected to the output shaft of the motor 5. The cam 6 is located on the upper side of the elastic pressing assembly 2. The motor 5 is electrically connected to the control unit, and the operation of the motor 5 can be intelligently controlled by the control unit. Regarding the structure of the cam 6, as shown in FIG. Figure 6 As shown, the cam 6 specifically includes a rotating wheel 601 and a convex portion 602, wherein the convex portion 602 is disposed on the outer peripheral side of the rotating wheel 601, and the convex portion 602 can contact the top of the elastic pressing component 2;

[0035] When the water outlet 4 needs to be closed, the motor 5 drives the cam 6 to rotate when in operation, and the rotating cam 6 can exert downward force on the elastic pressing component 2, thereby realizing that the driving component 500 is used to drive the elastic pressing component 2 to move, and drive the leak-proof valve stem 3 to move downward, so that the leak-proof valve stem 3 closes the water outlet 4. At this time, hot water can be stored in the water storage tank 1 for subsequent use in making tea;

[0036] When the water outlet 4 needs to be opened, the motor 5 drives the cam 6 to rotate. Since the elastic pressing component 2 always has a tendency to drive the leak-proof valve stem 3 to move away from the bottom of the water storage tank 1, the leak-proof valve stem 3 gradually moves up along the top of the water outlet 4 during the process of the cam 6 disengaging from the top of the elastic pressing component 2, so that the water outlet 4 is opened to drain water.

[0037] As shown above, under normal conditions, the convex portion 602 of the cam 6 presses the elastic pressing component 2 downward, driving the leak-stopping valve stem 3 to close the water outlet 4, and the instant heating module passes hot water into the water tank 1, and a preset capacity of hot water is injected into the water tank 1. When the hot water in the water tank 1 is needed to make tea, the control unit controls the motor 5 to rotate, and the rotating motor 5 drives the cam 6 to rotate. The convex portion 602 of the cam 6 gradually disengages from the top of the elastic pressing component 2, causing the leak-stopping valve stem 3 to gradually move up along the top of the water outlet 4, so that the water outlet 4 achieves the purpose of opening and draining water; and, through the mutual cooperation of the elastic pressing component 2, the leak-stopping valve stem 3, the motor 5 and the cam 6, the overall structure is simple, and the water outlet 4 can be opened or closed by controlling the rotation of the motor 5. The overall structure is stable, not easy to be damaged, and has a long service life, which improves the user experience.

[0038] In one possible implementation, Figure 4 As shown, the elastic pressing assembly 2 includes a sliding seat 201 and an elastic member 202;

[0039] The sliding seat 201 is disposed on the water storage tank 1, and the sliding seat 201 can be slidably installed on the water storage tank 1 along the up and down directions; the elastic member 202 is disposed at the bottom of the sliding seat 201;

[0040] A mounting seat 203 is provided on the top of the water tank 1, and a sliding seat 201 is slidably mounted inside the mounting seat 203. More specifically, a sliding block 7 is provided on the sliding seat 201, and at least a portion of the sliding block 7 protrudes from the outer peripheral side of the sliding seat 201. Figure 3 The number of sliding blocks 7 shown in the figure is two, and the two sliding blocks 7 are symmetrically arranged on the outer side of the sliding seat 201. A sliding groove 8 is provided on the wall of the mounting seat body 203, and the sliding blocks 7 are slidably connected to the sliding groove 8. Through the mutual cooperation between the sliding blocks 7 and the sliding groove 8, the sliding seat 201 can slide on the seat body 203 in the up and down direction;

[0041] The top of the stop-leak valve stem 3 is connected to the bottom of the sliding seat 201, so that the sliding seat 201 that slides up and down can drive the stop-leak valve stem 3 to move up and down to open or close the water outlet 4 at the bottom of the stop-leak valve stem 3;

[0042] In order to ensure that the sliding seat 201 always has the tendency to drive the stop-leak valve stem 3 to move away from the bottom of the water tank 1, the elastic member 202 is a compression spring, and the elastic member 202 is located between the mounting seat body 203 and the sliding seat 201. Specifically, a boss 10 is provided on the bottom of the mounting seat body 203, and the elastic member 202 is sleeved to the outside of the boss 10. A through hole is opened on the top of the boss 10, and the bottom of the sliding seat 201 is connected to the stop-leak valve stem 3 inside the water tank 1 through the through hole.

[0044] Specifically, when hot water is stored in the water tank 1, the water vapor in the water tank 1 is discharged to the outside of the water tank 1 through the connecting port 302, thereby realizing the pressure relief function. When the hot water in the water tank 1 enters abnormally and the amount of hot water in the water tank 1 is too large, the hot water can overflow along the connecting port 302 to the outside of the water tank 1.

[0045] In one possible implementation, Figure 3 or Figure 4 As shown, in order to facilitate monitoring and controlling the operation of the motor 5, so as to achieve the purpose of intelligently controlling the water outlet 4, a sensor 9 is provided on one side of the elastic pressing component 2, and the sensor 9 is a photoelectric sensor or a proximity switch, and the sensor 9 is provided on one side of one of the sliding blocks 7;

[0046] Specifically, the motor 5 drives the cam 6 to push the sliding seat 201 downward, so that the leak-proof valve stem 3 moves downward, and the leak-proof valve stem 3 closes the water outlet 4; when the water outlet 4 is opened, the motor 5 drives the convex part of the cam 6 to disengage along the top of the sliding seat 201, and the leak-proof valve stem 3, the sliding seat 201 and the sliding block 7 move upward as a whole under the action of the elastic member 202, and the upward sliding block 7 touches the sensor 9, and the control unit controls the motor 5 to stop rotating. When the hot water in the water tank 1 is discharged along the water outlet 4, the control unit controls the motor 5 to drive the convex part of the cam 6 to rotate and reset, and the motor 5 drives the cam 6 to push the sliding seat 201 downward, so that the leak-proof valve stem 3 moves downward, and the leak-proof valve stem 3 closes the water outlet 4.
