Description

Technical Field

[0001] The utility model relates to the technical field of teapots, in particular to an efficient extraction cold-brew teapot. Background Art

[0002] Tea drinking is one of the traditional eating habits of people. The traditional tea brewing method generally uses high-temperature hot water above 80°C to brew tea leaves, and makes catechins and amino acids in the tea leaves quickly released to have an aromatic taste. However, if the high-temperature tea brewing method is soaked for too long, a large amount of theophylline in the tea leaves will be released, making the tea water have a bitter taste, which easily causes the problem of failed tea brewing; in addition, in summer, people like to drink cold beverages, and the high-temperature tea water does not meet people's needs in hot weather.

[0003] In view of this, another type of cold-brew tea has been developed at present. This cold-brew tea does not need to use high-temperature hot water and can provide cold tea beverages. The existing manufacturing method of cold-brew tea mainly places tea leaves and cold water in a container for several hours (about 10 hours), so that catechins and amino acids in the tea leaves can be slowly dissolved and released. After soaking for a long time and pouring out, the cold tea beverage can be drunk without cooling, and the release of theophylline in the tea leaves can be reduced, and the bitter taste of the tea water can be reduced.

[0004] However, for tea merchants, cold-brew tea must soak cold water and tea leaves for a long time to release the aromatic catechins in the tea leaves to produce a better-tasting cold-brew tea, resulting in slow manufacturing efficiency and a longer brewing time. Therefore, the traditional cold-brew tea manufacturing method is difficult to meet the sales needs of tea merchants. Content of the Utility Model

[0005] The purpose of the utility model is to provide an efficient extraction cold-brew teapot to solve the technical problem that the cold-brew tea in the prior art uses a cold water brewing process, resulting in a longer brewing time.

The oxygen injection pump of the oxygen injection mechanism injects gas into the tea water inside the teapot body through the oxygen injection pipe and the oxygen injection nozzle. A large number of tiny bubbles are formed in the tea water.

[0034] The present utility model provides an efficient extraction cold brew tea pot that reduces the brewing time and improves the brewing effect.

[0035] The following combines Figures 1 to 6 to elaborate more details on the technical solutions provided by the present utility model.

[0036] The utility model provides an efficient extraction cold-brewing teapot, which comprises a teapot body 10, and a stirring mechanism 11 and an oxygen injection mechanism 14 are arranged on the teapot body 10;

[0037] The oxygen injection mechanism 14 includes an oxygen injection pump 15, an oxygen injection trachea 16 and an oxygen injection nozzle 17. The oxygen injection nozzle 17 is arranged at the bottom of the teapot body 10, and the oxygen injection pump 15 is connected with the oxygen injection nozzle 17 through the oxygen injection trachea 16;

[0038] The stirring mechanism 11 is used for stirring the tea water in the teapot body 10 after the oxygen injection pump 15 injects gas into the tea water in the teapot body 10.

[0039] For the efficient extraction cold-brewing teapot provided by the utility model, the teapot body 10 is provided with a stirring mechanism 11 and an oxygen injection mechanism 14. The oxygen injection pump 15 of the oxygen injection mechanism 14 injects gas into the tea water in the teapot body 10 through the oxygen injection trachea 16 and the oxygen injection nozzle 17. A large number of tiny bubbles are formed in the tea water. When the tiny bubbles burst, energy transfer will occur. The kinetic energy of water molecules increases, and the water molecules accelerate to penetrate into the interior of the tea leaves, extracting substances such as catechins and tea polyphenols inside the tea leaves, thereby reducing the brewing time and improving the brewing effect.

[0040] Secondly, a stirring mechanism 11 is further arranged on the teapot body 10. The stirring mechanism 11 is used for stirring the tea water in the teapot body 10 after the oxygen injection pump 15 injects gas into the tea water in the teapot body 10, increasing the mixing effect of the tea leaves and water molecules, extracting substances such as catechins and tea polyphenols inside the tea leaves, thereby reducing the brewing time and improving the brewing effect.

[0041] In addition, since the tiny bubbles adhere to the tea leaves, the stirring of the stirring mechanism 11 can disturb the water in the teapot body 10 to create a vortex, accelerating the bursting of the small bubbles adhering to the tea leaves. When the small bubbles burst, energy transfer will occur. The kinetic energy of water molecules increases, and the water molecules accelerate to penetrate into the interior of the tea leaves, extracting substances such as catechins and tea polyphenols inside the tea leaves, thereby reducing the brewing time and improving the brewing effect.

[0042] It should be noted that the oxygen injection mechanism 14 is used for injecting gas into the tea water in the teapot body 10. The energy transfer at the moment when the bubbles burst can increase the mixing effect of the tea leaves and water, thereby reducing the brewing time; the stirring of the stirring mechanism 11 can also increase the mixing effect of the tea leaves and water, thereby reducing the brewing time. The oxygen injection mechanism 14 and the stirring mechanism 11 can work independently or cooperate with each other to reduce the brewing time and improve the brewing effect.

[0043] It can be understood that when the oxygen injection mechanism 14 and the stirring mechanism 11 work together, the preferred working process is as follows: First, add cold water and tea leaves into the teapot body 10. After setting the brewing time, start the oxygen injection pump 15. The oxygen injection pump 15 can generate a large number of tiny bubbles, and the tiny bubbles adhere to the tea leaves. After the oxygen injection pump 15 works for X seconds, the stirring mechanism 11 starts to work (at this time, the oxygen injection pump 15 and the stirring mechanism 11 work simultaneously). The stirring mechanism 11 slowly disturbs the water in the pot, creating a vortex, accelerating the rupture of the small bubbles adhering to the tea leaves. At the moment when the small bubbles rupture, energy transfer occurs, the kinetic energy of water molecules increases, and the water molecules accelerate to penetrate into the interior of the tea leaves, extracting substances such as catechins and tea polyphenols inside the tea leaves. For different brewing times, the rate of the oxygen injection pump 15 and the rotation speed of the stirring mechanism 11 are different, which can be pre-matched and set through the whole machine program.

[0044] In some embodiments of the present invention, the stirring mechanism 11 includes a stirring motor 12 and a rotating dial 13. The rotating dial 13 is arranged inside the teapot body 10, and the rotating dial 13 is connected to the stirring motor 12 to drive the rotating dial 13 to rotate.

[0045] In some embodiments of the present invention, the stirring mechanism 11 includes a stirring motor 12 and a rotating dial 13. The rotating dial 13 is arranged inside the teapot body 10, and the stirring motor 12 is used to drive the rotating dial 13 to rotate, thereby stirring the tea water in the teapot body 10, so as to achieve the purpose of stirring, reduce the brewing time and improve the brewing effect.

[0046] It can be understood that the rotating dial 13 can be directly arranged inside the teapot body 10 or outside the teapot body 10. When in need of use, it can extend into the teapot body 10 to achieve the purpose of stirring the tea water.

[0047] In some embodiments of the present invention, a plurality of protrusions 18 are arranged on the rotating dial 13, and the plurality of protrusions 18 are annularly and arrayedly distributed on the rotating dial 13.

[0048] In some of the above embodiments of the present invention, a plurality of protrusions 18 are arranged on the rotating dial 13, and the plurality of protrusions 18 are annularly and arrayedly distributed on the rotating dial 13. When the rotating dial 13 rotates, the plurality of protrusions 18 can make the tea water form a rotating effect, with a better vortex effect, accelerating the stirring effect of the tea water in the teapot body 10, promoting the water molecules to accelerate to penetrate into the interior of the tea leaves, extracting substances such as catechins and tea polyphenols inside the tea leaves, thereby reducing the brewing time and improving the brewing effect.

[0049] It can be understood that when the rotating dial 13 is arranged at the bottom of the teapot body 10, the protrusion 18 is arranged above the rotating dial 13 to stir the tea water in the teapot body 10; when the rotating dial 13 is arranged below the tea water level in the teapot body 10, the protrusion 18 is arranged below the rotating dial 13 to stir the tea water in the teapot body 10. The specific setting position of the protrusion 18 can be adjusted according to actual needs.

[0050] In some embodiments, the protrusion 18 can be arranged on the upper and lower surfaces of the rotating dial 13.

[0051] In some embodiments of the present invention, three protrusions 18 are provided, and the three protrusions 18 are annularly arrayed on the rotating dial 13.

[0052] In some of the above embodiments of the present invention, three protrusions 18 are provided, and the three protrusions 18 are annularly arrayed. When the rotating dial 13 rotates, the three protrusions 18 further cause water flow disturbance, improve the tea mixing effect and brewing effect, and reduce the brewing time.

[0053] In some embodiments of the present invention, a brewing chamber 19 and a control chamber 20 are arranged in the teapot body 10. The stirring motor 12 and the oxygen injection pump 15 are both arranged in the control chamber 20, and the rotating dial 13 and the oxygen injection nozzle 17 are both arranged in the brewing chamber 19.

[0054] In some of the above embodiments of the present invention, a brewing chamber 19 and a control chamber 20 are arranged in the teapot body 10. The brewing chamber 19 is used to store tea leaves and water. The rotating dial 13 and the oxygen injection nozzle 17 are both arranged in the brewing chamber 19. The stirring motor 12 and the oxygen injection pump 15 are both arranged in the control chamber 20. The rotating dial 13 and the oxygen injection nozzle 17 are respectively used to stir the tea water and inject gas into the tea water, so as to accelerate the rupture of small bubbles adhering to the tea leaves. When the small bubbles rupture instantaneously, energy transfer occurs, the kinetic energy of water molecules increases, and the water molecules accelerate to penetrate into the interior of the tea leaves, extracting substances such as catechins and tea polyphenols inside the tea leaves.

[0055] It can be understood that the stirring motor 12 and the rotating dial 13 are respectively arranged in the control chamber 20 and the brewing chamber 19, and the oxygen injection pump 15 and the oxygen injection nozzle 17 are respectively arranged in the control chamber 20 and the brewing chamber 19, so as to ensure that the stirring motor 12 and the oxygen injection pump 15 can be isolated from water, effectively protecting the stirring motor 12 and the oxygen injection pump 15.

[0058] In some embodiments of the present utility model, an air inlet hole 22 is provided on the teapot body 10, and the air inlet hole 22 is communicated with the control chamber 20.

[0059] In some of the above embodiments of the present utility model, an air inlet hole 22 is provided on the teapot body 10. The air inlet is communicated with the control chamber 20 and is used for the oxygen injection pump 15 to suck air.

[0060] In some embodiments of the present utility model, the oxygen injection nozzle 17 includes a nozzle body. A plurality of spray holes are provided on the nozzle body, and a one-way valve is provided inside the nozzle body.
