[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] refer to Figures 1 to 9 As shown, a tea extractor includes a body 1 and a tea extractor 2. The body 1 has a side-opening tea receiving chamber 101, in which a tea cup 13 can be movably placed and removed. A drain outlet 102 is located at the top of the tea receiving chamber 101 corresponding to the position of the tea cup 13. The tea extractor 2 is detachably mounted on the upper side of the body 1. A teapot cavity 201 communicating with the drain outlet 102 is defined within the tea extractor 2. A water inlet check valve assembly 3 communicating with the teapot cavity 201 and a drain outlet are located at the bottom of the tea extractor 2. The check valve assembly 4 includes an inlet pipe 5 on the top surface of the body 1 that can open the water inlet check valve assembly 3, and a drain connector 6 that connects to the drain check valve assembly 4. The body 1 contains a water pump 7, the pumping end of which is connected to an external water source W, and the draining end of which is connected to the inlet pipe 5. The drain connector 6 is connected to the drain outlet 102 via a water pipe. The body 1 also contains a solenoid valve 8, the movable part of which is connected to a push rod 9 that can open the drain check valve assembly 4.

[0029] This tea brewer can automatically brew tea leaves with heated hot water without manual operation. The system X controls the water pump 7 and solenoid valve 8 to automatically add water to the teapot and automatically pour the brewed tea into the teacup. It is fully automatic, safe and convenient, saving time and improving the user experience by eliminating the need for manual water addition and tea pouring.

[0030] Furthermore, the inlet water check valve assembly 3 and the outlet water check valve assembly 4 can smoothly connect or disconnect the inlet and outlet water passages during the teapot 2 being picked up or put down. When the teapot 2 is lifted, it can prevent water leakage from the inlet and outlet water passages. The operation is simple and convenient.

[0031] The bottom of the teapot 2 is connected to an upper coupler 10, and the drain check valve assembly 4 is tightly connected to the center of the upper coupler 10; the top surface of the body 1 is provided with a lower coupler 11 that is electrically coupled to the upper coupler 10, and the water inlet pipe 5 is elastically connected to the center of the lower coupler 11.

[0032] The cooperation of the upper coupler 10 and the lower coupler 11 enables the connection of high voltage and low voltage between the body 1 and the teapot 2. The upper coupler 10 and the lower coupler 11 are five-ring couplers. Five-ring coupler technology is mature and has low operating cost.

[0033] The top wall of the tea-receiving cavity 101 is equipped with several downward-illuminating LED beads 12, which surround the tea-receiving cup 13. The tea-receiving cup 13 is a glass tea-receiving cup. By illuminating the tea-receiving cavity 101 with the LED beads 12, when used with the glass tea-receiving cup, the glass tea-receiving cup and the tea can refract or scatter the light within the tea-receiving cavity 101, thus creating a beautiful ambient lighting effect. In addition to illuminating the tea-receiving cup 13, it can also enhance the aesthetics of the tea brewing device.

[0034] In this embodiment, the water inlet check valve assembly 3 includes an inlet sleeve 31, which defines an inlet channel 301. An elastic leak-proof cap 32, a first spring 33, a first steel ball 34, and an elastic leak-proof sleeve 35 are sequentially arranged from top to bottom within the inlet channel 301. A spring support 36 is provided at the upper part of the inlet sleeve 31. The elastic leak-proof cap 32 is connected to the spring support 36. The first spring 33 abuts against the spring support 36 and the first steel ball 34. The elastic leak-proof sleeve 35 is fastened to the bottom port of the inlet sleeve 31. The opening and closing of the inlet channel 301 is achieved through the cooperation of the first steel ball 34 and the elastic leak-proof sleeve 35.

[0035] When the water inlet check valve assembly 3 corresponds to the above structure, the top end of the water inlet pipe 5 extends to a water inlet nozzle 51 that is inserted into the elastic leak-proof cap 32, and the top end of the water inlet nozzle 51 extends to a pin 52 that pushes up the first steel ball 34 after insertion; after the teapot 2 is placed in the body 1, the pin 52 pushes up the first steel ball 34 and leaves the elastic leak-proof sleeve 35, opening the first switch of the water inlet channel 301. After the pressurized water flow enters the water inlet channel 30, the water flow pushes open the elastic leak-proof cap 32 again, thereby fully opening the water inlet channel 30, and finally the water flow enters the pot cavity to realize automatic water filling;

[0036] After the teapot 2 is lifted, the water inlet pipe 5 leaves the water inlet check valve assembly 3, and the first steel ball 34 and the elastic leak-proof cap 32 return to their initial positions, thereby closing the water inlet channel 301 and preventing water leakage from the water inlet channel 301.

[0037] In this embodiment, the drain check valve assembly 4 includes a drain sleeve 41, which defines a drain channel 401. The drain channel 401 includes an elastic sealing ring 42, a second spring 43, a second steel ball 44, and a leak-proof washer 45 arranged sequentially from top to bottom. The elastic sealing ring 42 is sleeved on the top of the drain channel 401 and also seals the gap between the drain sleeve 41 and the heating plate 23. The second spring 43 abuts against the elastic sealing ring 42 and the second steel ball 44. A support ring 46 extends from the bottom of the drain channel 401, and the leak-proof washer 45 is sleeved on the outside of the support ring 46. The opening and closing of the drain channel 401 is achieved through the cooperation of the second steel ball 44 and the leak-proof washer 45.

[0038] After the teapot 2 is placed in the body 1, the drain connector 6 is sleeved on the bottom end of the drain sleeve 41. Then the system starts the solenoid valve 8. The moving part of the solenoid valve 8 drives the push rod 9 to move upward and lift the second steel ball 44. The second steel ball 44 leaves the anti-leakage washer 45 and opens the drain channel 401. The tea water in the pot cavity 201 will flow through the drain channel 401, drain connector 6, water pipe, and drain outlet 102 in sequence, and finally flow into the water cup 13 for collection, realizing automatic water dispensing.

[0039] After the teapot 2 is lifted, the push rod 9 leaves the drain check valve assembly 4, and the second steel ball 44 returns to its initial position under the elastic potential energy of the second spring 43, thereby closing the drain channel 401. Even if the teapot 2 is suddenly lifted during the water discharge process, the drain channel 401 can still be quickly cut off to prevent further drainage.

[0040] The teapot 2 includes a body 21, a bottom shell 22, a heating plate 23, and a lid 24. The heating plate 23 is connected to the bottom opening of the body 21, and the lid 24 is fitted onto the mouth of the body 21. The bottom shell 22 is connected to the bottom of the body 21. The water inlet check valve assembly 3, the drain check valve assembly 4, and the upper coupler 10 are fixed between the heating plate 23 and the bottom shell 22. The heating plate 23 has a drain hole 231 corresponding to the drain check valve assembly 4. The water inlet of the water inlet check valve assembly 3 passes through the heating plate 23 and extends into the pot cavity 201.

[0041] The teapot 2 also includes an energy-concentrating cover 25, a hot water conduit 26, and a filter cup 27. The energy-concentrating cover 25 covers the upper side of the heating plate 23 and defines an energy-concentrating cavity 202 between the cover and the heating plate 23. The energy-concentrating cavity 202 is connected to the pot cavity 201. The hot water conduit 26 is connected to the energy-concentrating cover 25. The filter cup 27 is placed at the mouth of the pot. The upper part of the hot water conduit 26 is inserted into the filter cup 27 and connects the energy-concentrating cavity 202 with the inner cavity of the filter cup 27.

[0042] In the above-mentioned teapot 2 structure, the heating plate 23 heats the water in the energy-concentrating cavity 202. The energy-concentrating cavity 202 can improve the effect of heating the water to boiling. The heated hot water enters the hot water pipe 26 under pressure and then flows into the filter cup 27 to brew the tea in the filter cup 27. The extracted tea water is then filtered and flows back into the pot cavity 201. This structure isolates the tea leaves from the water to prevent the tea leaves from being steeped for too long. Moreover, the high temperature water can improve the taste of the tea.

[0043] The top surface of the body 1 is provided with a teapot placement cavity 103. The lower coupler 11 is located in the center of the teapot placement cavity 103, and the drain connector 6 is located on the side of the lower coupler 11. When the bottom of the teapot 2 is embedded in the teapot placement cavity 103, the upper coupler 10 is coupled with the lower coupler 11. The teapot placement cavity 103 enables the top surface of the body 1 to stably place the teapot 2, making it less likely for the teapot 2 to be knocked over.

[0044] The cavity wall of the pot body placement cavity 103 is provided with a foolproof step 104, and the bottom of the tea brewing pot 2 is provided with a foolproof concave corner 28. When the tea brewing pot 2 is inserted into the pot body placement cavity 103, the drain check valve assembly 4 is connected to the drain connector 6 through the cooperation of the foolproof step 104 and the foolproof concave corner 28.

[0045] Since the drain connector 6 is located on the side of the lower coupler 11, the teapot 2 and the pot body placement cavity 103 have only one matching angle. Therefore, through the foolproof step 104 and the foolproof concave angle 28, it can be ensured that the user can rotate the teapot 2 to the indicated matching angle before the teapot 2 can be completely placed in the pot body placement cavity 103.

[0046] The body 1 is equipped with a heat preservation structure corresponding to the tea cavity 101;

[0047] In this embodiment, the body 1 forms a tea cup support platform 106 at the bottom of the tea cavity 101. In this embodiment, the heat preservation structure is set on the tea cup support platform 106 and is used to heat the tea cup 13 to achieve the heat preservation function. The heat preservation structure is a heating element 14, which includes a heating film, heating wire, heating tube, or heating plate, etc.

[0048] The water pump 7 has an inlet hose 71 connected to the drain end of the water pump 7 and the inlet pipe 5. A support spring 72 is provided inside the inlet hose 71 along its length. The support spring 72 can support the inlet hose 71 and prevent the inlet hose 71 from being bent or flattened, which would reduce the flow cross-sectional area of ​​the inlet hose 71 or cause it to be completely blocked, which would easily damage the water pump 7.

[0049] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
