[0058] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, however, the present application can also be implemented in other different manners from those described herein, and therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0059] Some embodiments provided by the present application will be described below with reference to Figures 1 to 2 to provide a cold brewing machine 100.

[0060] Embodiment one:

[0061] As shown in Figure 1 and Figure 2 , the embodiment of the first aspect of the present application provides a cold brewing machine 100, the cold brewing machine 100 comprising: a housing 110, the housing 110 being provided with a containing cavity; a container 120, the container 120 being detachably arranged in the containing cavity, the container 120 being provided with a first cavity 121 and a second cavity 122; an ultrasonic wave generating device 130, the ultrasonic wave generating device 130 being arranged in the second cavity 122, part of the ultrasonic wave generating device 130 extending into the first cavity 121; a refrigeration assembly 140, the refrigeration assembly 140 being arranged in the housing 110, the refrigeration assembly 140 being used for heat exchange with the first cavity 121.

[0062] The cold brewing machine 100 provided by the embodiment of the present application comprises the housing 110, the container 120, the ultrasonic wave generating device 130 and the refrigeration assembly 140, specifically, the housing 110 is provided with the containing cavity, and the container 120 is detachably arranged in the containing cavity, that is, when the container 120 is arranged in the containing cavity, food materials to be extracted, such as tea leaves, are placed in the container 120, the tea leaves are mixed with water in the container 120, and the preparation of cold brewed tea is realized. After the preparation of cold brewed tea is completed, the container 120 can be taken out of the housing 110 to pour out the prepared cold brewed tea for the user to drink. By detachably arranging the container 120 in the containing cavity, after the preparation of cold brewed tea is completed, the container 120 and the like can be easily cleaned, the cleaning difficulty is reduced, and thus the cleaning effect of the cold brewing machine 100 is improved, bacteria can be prevented from breeding in the container 120 or the tea outlet during the long-term use of the cold brewing machine 100, the cleaning effect is improved, and the user's use experience is improved.

[0063] The container 120 is provided with a first cavity 121 and a second cavity 122, that is, the container 120 is divided into the first cavity 121 and the second cavity 122 which are not communicated with each other, the ultrasonic wave generating device 130 is arranged in the second cavity 122, and part of the ultrasonic wave generating device 130 extends into the first cavity 121. It can be understood that the first cavity 121 is used for extraction of the food material to be extracted, by extending part of the ultrasonic wave generating device 130 into the first cavity 121, the ultrasonic wave generated by the ultrasonic wave generating device 130 can act on the cold water or ice water and the food material to be extracted in the first cavity 121, so that the cold water or ice water and the food material to be extracted in the first cavity 121 are oscillated, so that the beneficial ingredients in the food material to be extracted can be quickly extracted, and the taste of the tea product is improved. And by disturbing the cold water or ice water and the food material to be extracted in the first cavity 121 by the ultrasonic wave generating device 130, the extraction speed of the food material to be extracted can be accelerated, the extraction time is shortened, and the extraction effect is improved.

[0064] By arranging the ultrasonic wave generating device 130 in the second cavity 122 and extending part of the ultrasonic wave generating device 130 into the first cavity 121 to disturb the mixture in the first cavity 121, that is, the electrically connected part and the oscillation part of the ultrasonic wave generating device 130 are arranged in two cavities, that is, the electrically connected part and the oscillation part of the ultrasonic wave generating device 130 are separated. Since the food material to be extracted in the first cavity 121 is mostly a solid-liquid mixture, such as tea leaves and water, if the circuit part of the ultrasonic wave generating device 130 contacts water or other liquids, it is easy to cause short circuit, and thus the cold brewing machine 100 fails, reducing the service life of the cold brewing machine 100. By arranging the electrically connected part and the oscillation part of the ultrasonic wave generating device 130 in two cavities, the extraction of the food material to be extracted can be accelerated, and at the same time, the water or other liquids are prevented from contacting the circuit board part of the ultrasonic wave generating device 130, improving the use safety of the cold brewing machine 100 and effectively prolonging the service life of the cold brewing machine 100.

[0065] The refrigeration assembly 140 can exchange heat with the first cavity 121, that is, the refrigeration assembly 140 can cool the food material to be extracted in the first cavity 121 through the first cavity 121, so that the food material to be extracted can be cooled while being extracted, thereby realizing the preparation of cold-brewed tea and the like, without the need for a refrigerator or the like to cool the food material to be extracted, facilitating the preparation of cold-brewed tea, so that the cold-brewing machine 100 has the function of independently preparing cold-brewed tea, increases the application scenarios of the cold-brewing machine 100, and improves the practicality of the cold-brewing machine 100.

[0066] In practical applications, the container 120 is made of metal. On the one hand, metal has good thermal conductivity, which can improve the cooling efficiency and effect of the cooling component 140 on the extractable material in the first cavity 121. On the other hand, metal has a certain structural strength. When the ultrasonic generator 130 extends into the first cavity 121 and generates ultrasonic waves to vibrate the extractable material in the first cavity 121, the container 120 will generate a certain amount of friction with the inner wall of the cavity. By making the container 120 a metal material, the service life of the container 120 can be extended.

[0067] Example 2:

[0068] like Figure 1 As shown, based on the above embodiment, the cold extraction machine 100 further includes a separator 150 and a first through hole. The separator 150 is disposed inside the container 120 and divides the container 120 into a first cavity 121 and a second cavity 122. The first through hole is disposed in the separator 150, and part of the ultrasonic generator 130 extends into the first cavity 121 through the first through hole.

[0069] In this embodiment, the cold extraction machine 100 is further defined as including a separator 150 and a first through hole. Specifically, the separator 150 is provided inside the container 120, which divides the container 120 into a first cavity 121 and a second cavity 122. The ultrasonic generator 130 is disposed in the second cavity 122, and part of the ultrasonic generator 130 is extended into the first cavity 121 to disturb the mixture in the first cavity 121. That is, the electrical connection part and the oscillation part of the ultrasonic generator 130 are separated into two cavities, that is, the electrical connection part and the oscillation part of the ultrasonic generator 130 are separated. Since the substances to be extracted in the first cavity 121 are mostly solid-liquid mixtures, such as tea leaves and water, if the circuit part of the ultrasonic generator 130 comes into contact with water or other liquids, it is easy to cause a short circuit, which will lead to the malfunction of the cold extraction machine 100 and reduce the service life of the cold extraction machine 100. By separating the electrical connection part and the oscillation part of the ultrasonic generator 130 into two separate cavities, it is possible to accelerate the extraction of the extractant while preventing liquids such as water from contacting the circuit board part of the ultrasonic generator 130, thereby improving the safety of the cold extractor 100 and effectively extending its service life.

[0070] The separator 150 is provided with a first through hole. The part of the ultrasonic generator 130 that extends into the first cavity 121 extends into the first cavity 121 through the first through hole. The ultrasonic waves generated disturb the cold water or ice water and the extractant in the first cavity 121, promote the decomposition of beneficial components in the extractant, improve the taste of the tea, and accelerate the extraction speed, shorten the extraction time, and improve the extraction effect.

[0071] It should be noted that the separator 150 and the container 120 can be an integral structure. An integral structure has good mechanical properties, which improves the connection strength between the separator 150 and the container 120, extending the service life of the cold extraction machine 100. In addition, the integral structure facilitates processing and production, thereby reducing the production cost of the cold extraction machine 100.

[0072] In one specific embodiment, the cold extraction machine 100 further includes a first seal located in the first through hole and disposed between the separator 150 and part of the ultrasonic generator 130.

[0073] In this embodiment, the cold extraction machine 100 is further defined as including a first sealing element. Specifically, at the first through hole, a first sealing element is also provided between the separator 150 and the portion of the ultrasonic generator 130 extending into the first cavity 121 to seal between the portion of the ultrasonic generator 130 and the wall of the first through hole, so as to further seal and separate the first cavity 121 and the second cavity 122, preventing liquids such as water in the first cavity 121 from entering the second cavity 122 through the first through hole, thereby causing a short circuit or other danger in the circuit part of the ultrasonic generator 130, further improving the safety of the cold extraction machine 100 and extending the service life of the cold extraction machine 100.

[0074] In specific applications, the first sealing element can be made of an elastic material. Since the part of the ultrasonic generator 130 extending into the first cavity 121 will vibrate the cold water or ice water and the extractant in the first cavity 121 when the ultrasonic generator 130 is working, by setting the first sealing element as an elastic material, it can play a buffering role between the ultrasonic generator 130 and the separator 150, prevent wear between the ultrasonic generator 130 and the separator 150, and further extend the service life of the cold extraction machine 100.
