[0002] As people's living standards improve, their requirements for the quality and taste of tea drinks are also getting higher and higher. Traditional tea drinks use high-temperature extraction methods, which destroy the active ingredients in the tea leaves during extraction. Ultrasonic extraction technology, as a new extraction method, extracts at a lower temperature, while restoring the active ingredients of the tea leaves. It has the advantages of fast extraction speed, high efficiency, and better preservation of tea flavor and nutrients. However, in existing ultrasonic tea extraction devices, the direct contact between the tea leaves and the ultrasonic generator causes the tea leaves to be damaged and produce fragments and residues. Impurities such as tea fragments and residues are present in the extracted tea soup, making the tea soup turbid and difficult to filter, affecting the quality of the tea soup. Utility Model Content

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] like Figure 1-Figure 2As shown, a first embodiment of an ultrasonic tea extraction device of the present invention includes an ultrasonic generator 1, an extraction container 2, and a filter 4. The extraction container 2 contains an extract 5 and an extract 3. The extract 5 can be tea leaves or other edible plants. The filter 4 is placed in the chamber of the extraction container 2. The filter 4 is placed vertically into the chamber of the extraction container 2. The filter 4 is plate-shaped and has the same diameter as the extraction container 2. To facilitate the placement of the filter 4 in the extraction container 2, a distance equal to or less than the diameter of the filter holes is reserved between the edges of the filter 4 and the inner wall of the extraction container 2. The filter 4 has filter holes with adjustable apertures. The material of the filter 4 is preferably glass or stainless steel that has little effect on ultrasonic propagation. The filter 4 is placed vertically into the extraction container 2 through the upper opening of the extraction container 2. The filter 4 divides the chamber of the extraction container 2 into two, namely, an upper and lower chamber. The extract 5 is placed in the lower chamber, and the ultrasonic generator 1 is placed in the upper chamber. During use, an appropriate amount of extract 5 is placed in the extraction container 2, and the filter 4 is placed in the extraction container 2. Due to the weight of the filter 4, the extract 5 is pressed down. Then, the low-temperature extract 3 is added. The extract 3 and the extract 5 are mixed in a certain proportion. The height of the low-temperature extract 3 in the extraction container 2 is higher than the filter 4, allowing the extract 3 to completely immerse the filter 4. The ultrasonic transmission part of the ultrasonic generator 1 is placed in the upper chamber space and in contact with the extract. In addition, in the above operation, the extract 5 and the extract 3 can be poured into the extraction container 2 according to the ratio of the mixture, and the filter 4 is placed vertically in the extraction container 2. Due to the weight of the filter 4, the extract 5 is pressed down. The pore size of the filter 4 can only allow the extract 3 to pass through, but not the extract 5. The filter 4 intercepts the extract 5, allowing the extract 5 to remain in the lower chamber space. The ultrasonic transmission part of the ultrasonic generator 1 contacts the extract 3, and the ultrasonic wave passes through the pores of the filter 4 and propagates to the extract, performing an ultrasonic operation on the extract, so that the effective ingredients of the extract are quickly dissolved in the extract 3. The time of the ultrasonic operation is controlled according to the needs of making the beverage. After the ultrasonic operation is completed, the extract 3 is poured out of the extraction container 2, and the extract 5 is still retained in the extraction container 2 due to the isolation effect of the filter 4. After the ultrasonic extraction operation is completed, the tea drink can be directly poured into a teacup for drinking without secondary or multiple filtration.

[0016] like Figure 3-Figure 4As shown, a second embodiment of an ultrasonic tea extraction device of the present invention, compared with the first embodiment, a filter screen 4 is placed longitudinally in the extraction container 2, and the filter screen 4 can be movably supported by a support frame 41 in the space of the extraction container 2, so that the chamber space of the extraction container 2 is divided into upper and lower chamber spaces, and the extract 5 mixed with the extract liquid prepared in advance according to the ratio is poured into the extraction container 2, and the extract 5 cannot pass through the holes of the filter screen 4. The filter screen 4 isolates the extract liquid 3 mixed with the extract 5, so that the extract 5 is placed on the upper end surface of the filter screen 4, and the ultrasonic transmission part of the ultrasonic generator 1 performs ultrasonic work on the outer wall surface of the bottom of the extraction container 2 to extract the extract 5. After the extraction operation is completed, the filter screen 4 is taken out vertically upwards, and the extract 5 can be taken out of the extraction container 2.

[0017] like Figure 5 As shown, the third embodiment of the ultrasonic tea extraction device of the present invention, compared to the second embodiment, has a filter 4 placed longitudinally within the extraction container 2. The filter 4 is movably fixed within the extraction container 2 by a hanging rod 42. The hook of the hanging rod 42 is hooked to the upper end of the wall of the extraction container 2. After the extraction process is completed, the extract 5 in the extraction container 2 is removed by lifting the hook 42.

[0018] Based on the three aforementioned embodiments, the ultrasonic generator 1 extracts the extract 5 contained in the extraction container 2 while maintaining a certain distance from the extract 5. This prevents damage to the extract 5 and preserves the integrity of the extract 5. Furthermore, after the extraction is complete, the extract can be directly separated from the extraction liquid by utilizing the isolation function of the filter 4.

[0019] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
