DETAILED DESCRIPTION OF THE DISCLOSURE

(5) Drawings and detailed embodiments are combined hereinafter to elaborate the technical solutions of the present disclosure.

(6) The beverage brewing device of the present disclosure comprises a kettle body 1, a heating disc 2, and a tea-leaf basket 3, wherein the heating disc 2 and the tea-leaf basket 3 are located in the kettle body 1. An air cylinder mechanism 4 is fixed in the kettle body 1, a moving piston 5 is arranged in the inner cavity of the air cylinder mechanism 4, and the piston 5 is connected to the tea-leaf basket 3. The air cylinder mechanism 4 is connected to an air pump 12, and the air pump 12 is used for conveying a driving gas to the air cylinder mechanism 4. The piston 5 is driven by the driving gas, thereby driving the tea-leaf basket 3 to move in the kettle body 1. The beverage brewing device of the present disclosure can automatically drive the tea-leaf basket 3 to move up and down, has a simple structure and is cost-effective.

(7) In the first embodiment of the present disclosure, as shown in FIG. 1, the output end of the air pump 12 is connected to an electronic pressure relief valve 6, and the output end of the electronic pressure relief valve 6 is connected to a first air pipe 8 and a second air pipe 9 in parallel, wherein the first air pipe 8 and the second air pipe 9 are respectively connected to the first end and the second end of the air cylinder mechanism 4. When tea-leaves need to be replaced or added into the tea-leaf basket 3, the tea-leaf basket 3 needs to be lifted to the upper end of the kettle body 1. At this point, the air pump 12 is initiated to convey a driving gas, the electronic pressure relief valve 6 allows the second end of the air cylinder mechanism 4 to be communicated with the output end of the air pump 12, and allows the first end of the air cylinder mechanism 4 to be communicated with the pressure relief end of the electronic pressure relief valve 6. In this way, the driving gas enters the second end of the air cylinder mechanism 4 from the second air pipe 9, and the gas at the first end of the air cylinder mechanism 4 is discharged from the pressure relief end, enabling the piston 5 to move upward in the air cylinder mechanism 4. Thus, the tea-leaf basket 3 is driven by the piston 5 to move upward, allowing tea-leaves to be replaced or added into the tea-leaf basket 3 by a user. When tea-leaves need to be soaked, the tea-leaf basket 3 is required to be lowered into the interior of the kettle body 1. At this point, the air pump 12 is initiated to convey the driving gas, the electronic pressure relief valve 6 allows the first end of the air cylinder mechanism 4 to be communicated with the output end of the air pump 12, and allows the second end of the air cylinder mechanism 4 to be communicated with the pressure relief end of the electronic pressure relief valve 6. In this way, the driving gas enters the first end of the air cylinder mechanism 4 from the first air pipe 8, and the gas at the second end of the air cylinder mechanism 4 is discharged from the pressure relief end, thereby enabling the piston 5 to move downward in the air cylinder mechanism 4. Thus, the tea-leaf basket 3 is driven by the piston 5 to move downward, making the tea-leaf basket 3 stay in the kettle body 1 so that the tea-leaves are soaked in water inside the kettle body 1.

(8) In the second embodiment of the present disclosure, as shown in FIG. 2, the output end of the air pump 12 is connected to a pressure relief valve 7, and the output end of the pressure relief valve 7 is connected to the first end of the air cylinder mechanism 4 through the first air pipe 8. The second end of the air cylinder mechanism 4 is provided with an exhaust port, and the piston 5 is connected to a return spring 10. When tea-leaves need to be replaced or added to the tea-leaf basket 3, the tea-leaf basket 3 is required to be lifted to the upper end of the kettle body 1. At this point, the air pump 12 does not operate and the pressure relief valve 7 is turned on. In this way, the piston 5 moves upward under the action of the return spring 10. Meanwhile, the gas at the first end of the air cylinder mechanism 4 is discharged from the first air pipe 8 and the pressure relief valve 7, while the exhaust port 13 connected to the second end of the air cylinder mechanism 4 receives a gas, thereby balancing the air pressure at the two ends of the piston 5. In this way, the air pressure resistance of the return spring 10 that drives the piston 5 to move is eliminated, and the tea-leaf basket 3 can be driven by the piston 5 to move upward, allowing tea-leaves to be replaced or added into the tea-leaf basket 3 by the user. When tea-leaves need to be soaked, the tea-leaf basket 3 is required to be lowered into the interior of the kettle body 1. At this point, the air pump 12 is initiated to convey the driving gas, and the pressure relief valve 7 allows the first end of the air cylinder mechanism 4 to be communicated with the output end of the air pump 12. Thus, the driving gas enters the first end of the air cylinder mechanism 4 from the first air pipe 8, and the gas at the second end of the air cylinder mechanism 4 is discharged from the exhaust port 13. At this point, the air pressure at the first end of the air cylinder mechanism 4 overcomes the elastic force of the return spring 10, thereby enabling the piston 5 to move downward in the air cylinder mechanism 4. Under such circumstances, the tea-leaf basket 3 moves downward when being driven by the piston 5, and the tea-leaf basket 3 stays in the kettle body 1, enabling tea-leaves to be soaked in water inside the kettle body 1.

(9) In the third embodiment of the present disclosure, as shown in FIG. 3, the output end of the air pump 12 is connected to the lower end of the air cylinder mechanism 4 through a first air pipe 8, the piston 5 is telescopically moved via the upper end of the air cylinder mechanism 4, and a pressure relief valve 7 is connected to the first air pipe 8 in parallel. When tea-leaves need to be replaced or added into the tea-leaf basket 3, the tea-leaf basket 3 needs to be lifted to the upper end of the kettle body 1. At this point, the air pump 12 is initiated to convey a driving gas, and the pressure relief valve 7 is turned off, allowing the lower end of the air cylinder mechanism 4 to be communicated with the output end of the air pump 12. Thus, the driving gas enters the lower end of the air cylinder mechanism 4 from the first air pipe 8, and the piston 5 moves upward under the action of the air pressure. For being propelled by the piston 5, the tea-leaf basket 3 is lifted, allowing tea-leaves to be replaced or added into the tea-leaf basket 3 by the user. When tea-leaves need to be soaked, the tea-leaf basket 3 needs to be lowered to the interior of the kettle body 1. At this point, the air pump 12 does not work and the pressure relief valve 7 is turned on. In this way, the driving gas in the air cylinder mechanism 4 is discharged from the first air pipe 8 and the pressure relief valve 7. Meanwhile, under the self-weight of the piston 5 and the tea-leaf basket 3, the piston 5 moves downward in the air cylinder mechanism 4, enabling the tea-leaf basket 3 to move downward together with the piston 5. Thus, the tea-leaf basket 3 is located in the kettle body 1, and the tea-leaves are soaked in the water in the kettle body 1.

(10) In embodiment 1 or 2, the kettle body 1 is provided with a handle 11, and the first air pipe 8 is located in the inner cavity of the handle 11. Through adopting this arrangement, the air path becomes reasonable and simple.

(11) In embodiment 3, the piston 5 comprises a multi-stage telescopic piston 5, and the lifting of the tea-leaf basket 3 is achieved through the multi-stage telescopic piston 5. The tea-leaf basket 3 can be driven to move upward by a small air pressure, making the lifting of the tea-leaf basket 3 more flexible and rapid.

(12) Additionally, the air pump 12 is located at the bottom end of the kettle body 1 and is positioned underneath the heating disc, making the structural arrangement in the kettle body 1 more reasonable. Meanwhile, the air pump 12 is separated from the heating disc 2, thus being prevented from contacting with the water in the kettle body 1

(13) Further, the kettle body 1 is provided with an operation panel, wherein the operation panel is provided with a tea-leaf key used for controlling the air pump 12, and a temperature selection key used for controlling the heating disc 2 to heat at different temperatures. According to this design, the tea-brewing can be automized, achieving a simple and convenient operation.

(14) According to the beverage brewing device of the present disclosure, the air cylinder mechanism and the air pump interact to drive the tea-leaf basket to move in the kettle body. Thus, the soaking time of tea-leaves in the tea-leaf basket can be controlled by the user, and tea-leaves can be conveniently replaced or added into the tea-leaf basket. The structure driven by the air cylinder is simple and cost-effective.

(15) The above are only preferred embodiments of the present disclosure. Therefore, the equivalent changes or modifications made in accordance with the structure, features and principles described in the scope of the present disclosure should fall into the scope of the present disclosure.
