[0026] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the disclosure of this invention and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of this invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0027] In the description of the present invention, terms such as "up", "down", "left", "right", "front", and "back" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0028] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0029] This embodiment provides a water outlet control mechanism for a tea maker, referring to Figures 2 to 6As shown, it includes a driver 20, a lever 30 and a sealing plug assembly 10, wherein the sealing plug assembly 10 is disposed in the water outlet 40 of the tea maker 1 and blocks the water outlet 40 of the tea maker 1. Figure 3 As shown. The first force arm 31 of the lever 30 corresponds to the driver 20, and the second force arm 32 of the lever 30 corresponds to the sealing plug assembly 10. The driver 20 drives the sealing plug assembly 10 to move through the lever 30, thereby opening the water outlet 40; that is, the driving end of the driver 20 acts on the first force arm 31 of the lever 30, and drives the first force arm 31 to swing in a first direction (downward in this embodiment), so that the second force arm 32 of the lever 30 approaches the sealing plug assembly 10 in a second direction away from the first direction (upward in this embodiment), and drives the sealing plug assembly 10 to move, and finally the sealing plug assembly 10 releases the blockage of the water outlet 40, and the water outlet 40 can now discharge water normally, as shown in FIG. Figure 4 When the water outlet is completed, the sealing plug assembly 10 loses the force of the lever 30 and resets to re-block the water outlet 40.

[0030] Through the solution provided by this application, the water spout 40 of the tea maker 1 is sealed by a sealing plug assembly 10 disposed therein. A driver 20 disposed outside the water spout 40 actuates the sealing plug assembly 10, thereby opening the water spout 40 and controlling water flow from the spout 40. No electrical components are required within the spout 40, thus preventing damage caused by water vapor penetration. The solution provides stable water flow control and a long service life, and the structural requirements for the spout 40 are also reduced accordingly.

[0031] Furthermore, in this embodiment, the sealing plug assembly 10 can be vertically raised and lowered in the water outlet 40, and moves downward by its own gravity to block the water outlet 40; the driver 20 lifts the sealing plug assembly 10 through the lever 30 to open the water outlet 40; when the water is discharged, the driver 20 removes the driving force, the sealing plug assembly 10 loses the support of the lever 30, and falls under its own gravity until it blocks the water outlet 40.

[0032] In this way, the sealing plug assembly 10 does not need to be reset with the help of other external forces (such as reset by the elastic force of a spring, etc.), which can effectively avoid reset abnormalities caused by damage or fatigue of external components (such as when the elastic force of a spring is used for reset, the spring will produce elastic fatigue); its own gravity is not easily affected by other external factors, thereby making the sealing stability of the sealing plug assembly 10 better.

[0033] Furthermore, the sealing plug assembly 10 includes a guide rod 11 and a sealing member 12 and a counterweight 13 assembled on the guide rod 11. The guide rod 11 is guided and assembled in the water outlet 40 and extends out of the water outlet 40; the sealing member 12 is used to seal the water outlet 40; the second force arm 32 of the lever 30 corresponds to the lower end of the guide rod 11 extending out of the water outlet 40; and the counterweight 13 increases the weight of the sealing plug assembly 10 so that the sealing plug assembly 10 can move downward by its own gravity and seal the water outlet 40.

[0034] Further, such as Figure 6 As shown, the guide rod 11 is composed of a first section 111 and a second section 112 with a diameter larger than the first section 111. A limiting step 113 is formed at the connection between the first section 111 and the second section 112. The sealing plug assembly 10 also includes a gasket 14 and a fastening nut 15; the first section 111 is sequentially sleeved with the gasket 14, the sealing member 12, the counterweight 13 and the fastening nut 15 from bottom to top; the gasket 14 abuts on the limiting step 113, the sealing member 12 abuts on the gasket 14, and the counterweight 13 abuts on the sealing member 12. The fastening nut 15 is threadedly fitted on the first section 111 to fix the sealing member 12 and the counterweight 13, thereby realizing stable assembly of the sealing plug assembly 10.

[0035] Specifically, the sealing plug assembly 10 adopts the above-mentioned assembly structure, which achieves stable assembly and facilitates disassembly and assembly of the various components, and is one of the more preferred solutions. Of course, in other embodiments, the structure of the sealing plug assembly 10 is not limited to this. For example, when the weight of the guide rod 11 and the blocking member 12 is sufficient to automatically move downward to block the water outlet 40, the additional counterweight 13 structure can also be omitted; alternatively, the guide rod 11, the blocking member 12, and the counterweight 13 can be fixed together by means of a snap connection, etc.

[0036] The water outlet 40 of the tea maker 1 comprises a receiving cavity 41, a water passage 42, a clearance opening 43 and a water outlet 44. The receiving cavity 41, the water passage 42 and the clearance opening 43 are sequentially arranged along a straight line (in this embodiment, they are sequentially arranged from top to bottom in the vertical direction) and are connected. The diameter of the water passage 42 is smaller than that of the receiving cavity 41. The water outlet 44 is connected to the peripheral side of the water passage 42. The guide rod 11 is sequentially inserted through the receiving cavity 41, the water passage 42 and the clearance opening 43. 42 and the clearance opening 43, and extends out through the clearance opening 43; the blocking member 12 is located in the accommodating cavity 41 and abuts against the water passage 42 by sealing, thereby blocking the water outlet 40; when the sealing plug assembly 10 is lifted by the second lever arm 32 of the lever 30, the blocking member 12 disengages from the water passage 42, thereby opening the water outlet 40; after the water outlet 40 is opened, the tea passes through the accommodating cavity 41 and the water passage 42 in sequence, and finally flows out from the water outlet 44 on the side of the water passage 42. Specifically, multiple water outlets 44 can be provided, evenly distributed around the side of the water passage 42.

[0037] The accommodating chamber 41 is further equipped with a bracket 50 on the side (i.e., the upper side) away from the water passage 42. Specifically, the bracket 50 needs to be hollowed out to achieve water passage. A guide hole 51 is provided on the bracket 50, and the guide rod 11 is also passed through the guide hole 51 of the bracket 50. In this way, the upper end of the guide rod 11 is guided by the guide hole 51 of the bracket 50, while the lower end of the guide rod 11 is guided by the opening 43, thereby realizing the vertical lifting and lowering guidance of the sealing plug assembly 10. The movement of the sealing plug assembly 10 is more stable and not easy to be stuck. Of course, in other embodiments, the guide rod 11 can also form a guiding assembly with the water passage 42, and so on.

[0038] Specifically, the sealing member 12 is made of silicone (i.e., silica gel). Silicone has a certain elasticity and can achieve a good sealing effect when it abuts against the water passage 42. Silicone is also a safe material and will not release harmful substances when in contact with hot water. Of course, in other embodiments, food-grade PP (polypropylene) or rubber materials can also be used.

[0039] More specifically, the blocking member 12 has a conical abutting surface 121 facing the water passage 42. The inlet end of the water passage 42 is formed with a conical mating surface 421 that matches the conical abutting surface 121. The blocking member 12 seals against the conical mating surface 421 of the water passage 42 via the conical abutting surface 121. This arrangement allows for good contact with and sealing of the water passage 42, resulting in a better sealing effect. Of course, in other embodiments, the conical abutting surface 121 of the blocking member 12 can also be replaced with a flat abutting surface, achieving sealing by directly covering the inlet of the water passage 42, but this approach is less effective.

[0040] Furthermore, in this embodiment, the driver 20 includes a driving portion 21 and a movable rod 22. The driving portion 21 drives and connects to the movable rod 22 to drive the movable rod 22 to move toward or away from the first lever arm 31 of the lever 30. When the movable rod 22 moves toward the first lever arm 31 (i.e., moves downward), it drives the first lever arm 31 of the lever 30 to move in the first direction (i.e., downward), thereby pushing the lever 30 to move. Specifically, the driving portion 21 can use a cylinder or an electric push rod to directly drive the movable rod 22 to move, or it can use a motor to drive it. When a motor is used, the motor and the movable rod 22 can be connected through a transmission mechanism to convert the rotation of the motor into the lifting movement of the movable rod 22.

[0041] The water outlet control mechanism of the tea maker 1 described above, the sealing plug assembly 10 can also be driven to reset by means of a reset member (spring, etc.). When the reset member is used to drive the reset, the sealing plug assembly 10 does not need to be set to vertically lift, and can also be moved at an angle, as long as it can block and open the water outlet 40.

[0042] Further, continue to refer to Figures 1 to 6 As shown, this embodiment also provides a tea maker 1, wherein the water outlet of the water outlet nozzle 40 of the tea maker 1 is controlled by the water outlet control mechanism of the tea maker described above. Specifically, the tea maker 1 comprises a frame 2 and a tea cup 3 detachably mounted on the frame 2. The driver 20 is mounted on the frame 2 of the tea maker 1, and the water outlet nozzle 40 and lever 30 are both mounted on the tea cup 3 of the tea maker 1. This arrangement allows the tea cup 3 and its components (the sealing plug assembly 10, the water outlet nozzle 40, and the lever 30) to be individually removed from the module, facilitating assembly and maintenance.

[0043] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details of the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
