Description

Technical Field

[0001] This utility model relates to the field of kettle technology, and in particular to an ultrasonic cold brew kettle. Background Technology

[0002] Tea drinks are becoming increasingly popular, and their brewing methods are mainly divided into two categories: hot brewing and cold brewing. Hot brewing uses hot water at a specific temperature to brew tea leaves, coffee powder, fruit slices, and other ingredients; cold brewing uses cold water and usually requires several hours of steeping time to ensure that the ingredients are fully moistened. Ultrasonic extraction technology can effectively shorten this process.

[0003] Existing ultrasonic extraction pots typically consist of a pot body, an ultrasonic generator, and a power supply base. In use, tea ingredients are usually placed directly into the pot. The high-frequency vibrations generated by the ultrasonic generator create tiny bubbles in the water, accelerating the dissolution of flavor compounds in the ingredients. However, this direct placement method has significant limitations: the high-frequency vibrations are mainly concentrated at the bottom of the pot. After mixing with a large amount of water, the ingredients tend to float, making it difficult for them to fully contact the core vibration area. This results in a relatively long extraction time and fails to efficiently dissolve all flavor compounds.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an ultrasonic cold extraction pot, which uses an extraction chamber that can be separated from the lid to extend downward to above the isolation plate, guides the raw material to concentrate in the core area of ​​ultrasonic vibration, allows the raw material to fully interact with the high-frequency vibration, shortens the extraction time, and improves the cold extraction efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The extraction chamber extends downward above the partition plate, and a base plate is provided at the bottom of the extraction chamber, with ultrasonic transmission filter holes formed on the base plate. The outer peripheral wall of the extraction chamber is provided with extraction filter holes.

[0008] The ultrasonic cold extraction pot, wherein the extraction chamber includes a hollow guide portion, a lid lap edge surrounding the top edge of the guide portion, and a raw material placement portion integrally formed with and communicating with the bottom of the guide portion; the bottom plate is integrally formed with the bottom of the raw material placement portion; the lower surface of the pot lid is provided with a downwardly extending boss, the upper wall of the inner cavity of the guide portion is in close contact with the outer peripheral wall of the boss, and the lid lap edge abuts against the lower surface of the pot lid; the extraction filter hole is opened on the outer peripheral wall of the raw material placement portion.

[0009] In the ultrasonic cold extraction pot, the guide part is an inverted truncated cone, and the raw material placement part is a cylinder.

[0010] The ultrasonic cold brewing pot, wherein the mounting cavity is provided with a mounting groove, the mounting groove is provided with a sealing and noise-reducing adhesive, the sealing and noise-reducing adhesive has a slot, and the edge of the isolation sheet is located in the slot.

[0016] The ultrasonic cold brew pot, wherein the upper surface of the pot lid is provided with a handle.

[0017] Beneficial effects:

[0018] This invention provides an ultrasonic cold extraction pot. Through the design of an extraction chamber, and by extending the extraction chamber, the raw materials within it are confined to the core vibration area, preventing excessive floating and dispersion. This ensures continuous and sufficient contact with the high-frequency vibration, significantly shortening the extraction time and improving the dissolution efficiency of flavor compounds. The extraction chamber also serves as a separator, allowing users to directly pour out the cold extract or remove the extraction chamber from the pot by lifting the lid. This prevents the raw materials in the extraction chamber from continuously immersing in the cold source medium within the pot, thus avoiding an increase in the concentration of the extract.

Detailed Implementation

[0025] This utility model provides an ultrasonic cold brewing pot. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0026] Please see Figures 1-3This utility model provides an ultrasonic cold extraction pot, comprising a pot body 1 with an opening at the top and an installation cavity 11 at the bottom of the inner cavity, a pot lid 2 covering the top of the pot body 1, a separable extraction chamber 3 with an opening at the top and used in conjunction with the pot lid 2, an isolation plate 4 disposed in the installation cavity 11 and used to separate the pot body 1 and the installation cavity 11, an ultrasonic generator 5 disposed at the bottom of the isolation plate 4, and a base 6 for engaging with the bottom of the pot body 1 and for electrically connecting to the ultrasonic generator 5; the extraction chamber 3 extends downward to above the isolation plate 4, and a bottom plate 34 is provided at the bottom of the extraction chamber 3, on which ultrasonic transmission filter holes 341 are opened; the outer peripheral wall of the extraction chamber 3 is provided with extraction filter holes 331.

[0027] In use, the user holds the lid 2. Since the lid 2 works in conjunction with the extraction chamber 3, when the user lifts the lid 2, the extraction chamber 3 is removed from the pot body 1 along with it. Furthermore, the extraction chamber 3 and the lid 2 are detachable, allowing the user to remove the extraction chamber 3 from the lid 2 and fill it with the raw material to be extracted from the top. Cold water or other cold liquid is then poured into the pot body 1. After reassembling the extraction chamber 3 with the lid 2, the lid 2 is then placed back onto the pot body 1. The pot body 1 is then placed on the base 6, ensuring that the base 6 is electrically connected to the ultrasonic generator 5 at the bottom of the pot body 1. The base 6 supplies power to the ultrasonic generator 5, which then begins to operate, transmitting high-frequency vibrations to the liquid inside the pot body 1 through the insulating plate 4. This utilizes the cavitation effect to accelerate the extraction of flavor compounds from the raw material. Because the extraction chamber 3 extends downwards and is located directly above the separator 4, and the raw material is confined within the extraction chamber 3, with the area directly above the separator 4 being the core vibration region, the raw material remains in the area of ​​strongest vibration. High-frequency vibration is transmitted through the ultrasonic transmission filter 341 and extraction filter 331, rapidly penetrating the raw material within the extraction chamber 3, thus significantly shortening the extraction time. Furthermore, the extraction chamber 3 can also be used for sediment separation; after extraction, the cold extract can be directly poured out without additional filtration. Moreover, after extraction, opening the lid 2 along with the extraction chamber 3 prevents the raw material in the extraction chamber 3 from becoming increasingly concentrated due to continuous immersion in the liquid in the pot body 1, which would negatively impact the taste of the extract.

[0028] Please see Figure 2 , Figure 4 and Figure 5In some embodiments, the extraction chamber 3 includes a hollow guide portion 32, an integrally formed lid-fitting edge 31 surrounding the top edge of the guide portion 32, and a raw material placement portion 33 integrally formed and interconnected with the bottom of the guide portion 32; the base plate 34 is integrally formed with the bottom of the raw material placement portion 33; the lower surface of the lid 2 is provided with a downwardly extending boss 21, the upper wall of the inner cavity of the guide portion 32 is in close contact with the outer peripheral wall of the boss 21, and the lid-fitting edge 31 abuts against the lower surface of the lid 2; the extraction filter hole 331 is formed on the outer peripheral wall of the raw material placement portion 33. The boss 21 allows the upper parts of the lid 2 and the extraction chamber 3 to achieve an interference fit, resulting in a simple structure. The user can easily assemble the lid 2 and the extraction chamber 3 by pressing them together slightly. The lid-fitting edge 31 can support the lower surface of the lid 2, forming a surface contact and improving the sealing performance of the lid. Furthermore, since the extraction filter 331 is located on the raw material placement section 33 and not on the guide section 32, the raw material placed from above the guide section 32 can smoothly fall into the raw material placement section 33 after passing through the guide section 32, without leaking from the guide section 32 into the vessel body 1. In practical applications, the raw material placement section 33 is located above the separator 4. The closer it is to the separator 4, the stronger the cavitation effect, allowing the raw material above the separator 4 to be extracted quickly through high-frequency vibration.

[0029] Please see Figure 4 and Figure 5 In some embodiments, the guide portion 32 is an inverted truncated cone, and the raw material placement portion 33 is a cylinder. The inverted truncated cone design of the guide portion 32 results in a large diameter inlet at the top of the guide portion 32, preventing raw material spillage and facilitating user input. Furthermore, the inverted truncated cone forms a guide slope, allowing the raw material to smoothly fall into the raw material placement portion 33. The cylindrical design of the raw material placement portion 33 eliminates dead zones for raw material accumulation, ensuring even distribution, sufficient extraction, and easy cleaning of the extraction chamber 3.

[0030] Please see Figure 2 , Figure 5 In some embodiments, the mounting cavity 11 is provided with a mounting groove 41, please refer to [reference needed]. Figure 3 The mounting groove 41 is provided with a sealing and noise-reducing adhesive 7, and the sealing and noise-reducing adhesive 7 has a slot 71, in which the edge of the isolation piece 4 is located. The sealing and noise-reducing adhesive 7 further weakens vibration transmission and reduces noise during the operation of the cold brew pot. The slot 71 is used to fix the edge of the isolation piece 4, improve the stability of the isolation piece 4, reduce vibration displacement, and facilitate the installation of the isolation piece 4 into the mounting cavity 11 through the slot 71; moreover, the sealing and noise-reducing adhesive 7, together with the sealant, further enhances the sealing of the mounting cavity 11 and helps protect the internal components.

[0031] In some embodiments, the isolation plate 4 is a stainless steel isolation plate, and the ultrasonic generator 5 is a ceramic transducer vibrating plate. The ceramic transducer vibrating plate converts electrical energy into high-frequency vibration, which is efficiently transmitted to the liquid and raw materials above through the stainless steel isolation plate. The cavitation effect generated by the vibration accelerates the precipitation of flavor substances from the raw materials, achieving rapid cold extraction. The stainless steel isolation plate has advantages such as hardness and corrosion resistance, which can extend the service life of the cold extraction pot, while also blocking the liquid from the mounting cavity 11 and protecting the internal components.

[0032] Please see Figures 1-5 In some embodiments, the base 6 includes an upper cover 61 and a lower shell 62 that overlap each other. A circuit board 81 is disposed between the upper cover 61 and the lower shell 62. A terminal 82 is also disposed in the mounting cavity 11. The terminal 82 is electrically connected to the ultrasonic generator 5 through a contact 83. A power port 84 is disposed on the circuit board 81, and a power port 84 is also provided on the base 6. The power port 84 is located in the power port 84. After the power port 84 is connected to a power source, the current is regulated by the circuit board 81 in the base 6 and transmitted to the ultrasonic generator 5 through the terminal 82 and contact 83 in the mounting cavity 11. The ultrasonic generator 5 is powered by contact to generate high-frequency vibration. The upper cover 61 and the lower shell 62 cover and protect the circuit board 81. The cooperation of the terminal 82 and contact 83 realizes a stable electrical connection between the ultrasonic generator 5 and the circuit, ensuring the efficient operation of the cold extraction process. Specifically, the base 6 may also be equipped with a control panel or switch, so that the user can start the ultrasonic generator 5 by touching the control panel or pressing the button on the control panel.

[0033] Please see Figure 3 and Figure 5 In another embodiment, a first coil 13 is provided at the bottom of the kettle body 1, and a second coil 64 adapted to the first coil 13 is provided at the top of the base 6. Based on the principle of electromagnetic induction, it consists of two coils (a transmitting coil and a receiving coil). The transmitting coil is connected to an alternating current to generate an alternating magnetic field. When the receiving coil is in the magnetic field, a current is induced, thereby realizing wireless power transmission and non-contact power supply.

[0034] Please see Figure 1 In some embodiments, the upper side wall of the pot body 1 is provided with a spout 14 that communicates with the inner cavity of the pot body 1 and the outside. The spout 14 connects the inner cavity of the pot body 1 with the outside, ensuring that the air pressure inside the pot body 1 and the outside are consistent. In addition, it facilitates the direct pouring of the liquid after cold extraction without opening the lid 2 to pour it out, reducing liquid spillage.

[0035] Please see Figure 1In some embodiments, a handle 15 is provided on the side wall of the vessel body 1. The handle 15 provides a gripping fulcrum, making it easy to lift the vessel body 1 and preventing slippage caused by hand contact with the vessel body 1 when pouring or moving. In addition, it can also isolate the hand from direct contact with the vessel body 1, reducing the irritation to the hands from the low-temperature cold extract.

[0036] Please see Figure 1 In some embodiments, the lid 2 is also provided with a handle 22. The handle 22 provides a gripping fulcrum, making it convenient for the user to hold the handle 22 and apply upward force to open the lid 2.

[0037] In summary, this invention, by setting the extraction chamber 3, confines the raw materials in the vibration core area, avoids excessive floating and dispersion of the raw materials, and ensures that they are in continuous and sufficient contact with high-frequency vibration, significantly shortening the extraction time and improving the dissolution efficiency of flavor substances.
