Description

Technical Field

[0001] This invention relates to the field of kettles, and particularly to an ultrasonic extraction kettle. Background Technology

[0002] During the operation of the ultrasonic extraction pot, cold water, ice milk, or other cold source media are first injected into the pot. Then, the high-frequency vibration generated by the ultrasonic generator accelerates the release of flavor substances from the raw materials in the tea chamber.

[0003] The core structure of existing products mainly includes: a pot body for containing the cold source medium, an ultrasonic generator built into the bottom of the pot body cavity, a base for powering the generator, and a tea hopper for placing raw materials. When the tea hopper and ultrasonic generator are designed separately, the transmission path of ultrasonic energy must pass through the cold source medium inside the pot body, the tea hopper wall, and the raw materials (including the surrounding liquid) inside the tea hopper. Because the energy attenuates when propagating through multiple layers of media, the extraction speed of flavor substances is ultimately affected, resulting in low overall efficiency.

[0004] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide an ultrasonic extraction pot that integrates the tea container and the ultrasonic generator into the tea container lid, so that the high-frequency vibration generated by the ultrasonic waves can quickly act on the raw materials in the tea container and accelerate the extraction efficiency.

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

[0010] In the ultrasonic extraction pot, the lower surface of the tea chamber lid has a groove that is recessed into the inner cavity of the tea chamber lid and matches the top shape of the hollow boss. The positioning ring is disposed on the upper wall of the groove, and the groove is tightly fitted with the hollow boss. The lower surface of the second magnet is tightly fitted with the upper wall of the groove.

[0011] The ultrasonic extraction pot includes a tea chamber comprising a hollow guide portion, a lid-fitting edge surrounding the top edge of the guide portion, a raw material placement portion integrally formed with and communicating with the bottom of the guide portion, and a snap-fitting edge integrally formed with the raw material placement portion and extending outward around the edge of the raw material placement portion; the lid-fitting edge abuts against the lower surface of the pot lid, and the snap-fitting edge is separable from the tea chamber lid; the peripheral wall of the raw material placement portion is provided with filter holes.

Detailed Implementation

[0024] This invention provides an ultrasonic extraction vessel. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the scope of protection of the invention.

[0025] Please see Figure 1 and Figure 2The present invention provides an ultrasonic extraction pot, comprising a pot body 2, a pot lid 1 used in conjunction with the pot body 2, a tea compartment lid 3 separable from the pot body 2, a tea compartment 4 separable from the tea compartment lid 3, an ultrasonic generator 5 disposed in the inner cavity of the tea compartment lid 3 and located below the tea compartment 4, a positioning mechanism 6 for positioning the tea compartment lid 3 on the bottom of the inner cavity of the pot body 2, and a base 7 used in conjunction with the bottom of the pot body 2 and for electrically connecting to the ultrasonic generator 5.

[0026] In practical use, the bottom of the tea compartment 4 is sealed by the tea compartment lid 3 and the ultrasonic generator 5, so the raw materials to be extracted (such as tea leaves, coffee powder, etc.) can be directly placed into the hollow tea compartment 4. At this time, the ultrasonic generator 5 in the inner cavity of the tea compartment lid 3 is exactly located below the tea compartment 4. Subsequently, the tea compartment lid 3 and the tea compartment 4 are placed into the inner cavity of the pot body 2 by the positioning mechanism 6, so that the tea compartment lid 3 is accurately fixed to the bottom of the pot body 2, ensuring that the ultrasonic generator 5 and the base 7 at the bottom of the pot body 2 form a stable electrical connection path.

[0027] Next, inject an appropriate amount of cooling medium into the teapot body 2. Alternatively, you can inject the cooling medium into the teapot body 2 first, and then place the tea container lid 3 and the entire tea container 4 into the teapot body 2. After closing the teapot lid 1, start the base 7 to supply power. Under the fixing effect of the tea container lid 3, the ultrasonic generator 5 directly emits high-frequency vibration energy to the bottom of the tea container 4 directly above. The energy does not need to be transferred multiple times, but directly acts on the raw materials in the tea container 4 and the surrounding cooling medium through the bottom of the tea container 4. The high-frequency vibration accelerates the dissolution of the flavor substances of the raw materials into the cooling medium, achieving efficient extraction.

[0028] After extraction, disconnect the power supply to the base 7, and pour the extract from the spout 21 on the pot body 2 for drinking. When it is necessary to remove the tea container 4, open the pot lid 1, hold the tea container 4, and lift it directly upwards. Since the tea container 4 and the tea container lid 3 are detachable and the bottom is sealed, the remaining raw materials in the tea container 4 will be removed from the pot body 2 along with the tea container 4, avoiding the residue of raw materials in the pot body 2 or the cold source medium.

[0029] Throughout the process, the tea chamber lid 3 not only serves as the support and positioning function of the ultrasonic generator 5, but also works in conjunction with the ultrasonic generator 5 to achieve integrated material extraction by sealing the bottom of the tea chamber 4. At the same time, it shortens the transmission path of ultrasonic energy, reduces energy loss and improves extraction efficiency while ensuring the convenience of the split design.

[0030] Please see Figures 2-4In some embodiments, the positioning mechanism 6 includes a hollow boss 61 recessed into the inner cavity of the teapot body 2 at the bottom of the teapot body 2, a first magnet 62 fixedly disposed on the hollow boss 61, a positioning ring 64 extending upward from the bottom of the inner cavity of the tea container lid 3, and a second magnet 65 fixedly disposed in the positioning ring 64. The first magnet 62 and the second magnet 65 are magnetically attracted to each other. The hollow boss 61 mainly provides installation space for the first magnet 62, and the positioning ring 64 mainly provides installation space for the second magnet 65, so that the second magnet 65 can be stably disposed in the inner cavity of the tea container lid 3. When the first magnet 62 in the hollow boss 61 approaches the second magnet 65 in the positioning ring 64 (i.e., when the teapot body 2 and the tea container lid 3 are close), the magnetic force of opposite poles attracting each other will form a natural guiding force, guiding the tea container lid 3 to move towards a preset position at the bottom of the teapot body 2, and finally making the tea container lid 3 accurately positioned at the bottom of the inner cavity of the teapot body 2.

[0031] Please see Figure 3 and Figure 4 In some embodiments, a cover 63 is fixedly connected to the bottom of the kettle body 2. The cover 63 is fixedly disposed in the hollow boss 61. The upper surface of the cover 63 has a first mounting groove 631 whose shape matches the shape of the first magnet 62. The first magnet 62 is located in the first mounting groove 631, and the upper surface of the first magnet 62 is tightly fitted with the top surface of the inner cavity of the hollow boss 61. The cover 63 facilitates the installation of the first magnet 62 into the inner cavity of the hollow boss 61. The cover 63 can then be fixed in the inner cavity of the hollow boss 61 by welding or gluing. This not only facilitates the installation and concealment of the first magnet 62, but also prevents the cold source medium of the kettle body 2 from seeping into the inner cavity of the hollow boss 61, thus preventing the performance of the magnet from being affected by liquid corrosion.

[0032] Please see Figure 3In some embodiments, the lower surface of the tea container lid 3 has a groove 66 that is recessed into the inner cavity of the tea container lid 3 and matches the top shape of the hollow boss 61. The positioning ring 64 is disposed on the upper wall of the groove 66, and the groove 66 is tightly fitted with the hollow boss 61. The lower surface of the second magnet 65 is tightly fitted with the upper wall of the groove 66. The groove 66 formed by the recess on the lower surface of the tea container lid 3 matches the top of the hollow boss 61 and the two fit tightly, thus mechanically limiting the relative position of the tea container lid 3 and the teapot body 2 in both horizontal and vertical directions. The positioning ring 64 disposed on the upper wall of the groove 66 provides a mounting carrier for the second magnet 65 and ensures that the position of the second magnet 65 corresponds precisely to the first magnet 62 in the hollow boss 61. At the same time, the tight fit between the lower surface of the second magnet 65 and the upper wall of the groove 66 ensures that the magnetic attraction force between the second magnet 65 and the first magnet 62 is stable and concentrated. When the tea container lid 3 is placed into the teapot body 2, the slot 66 and the hollow protrusion 61 guide the tea container lid 3 to quickly enter the correct position. Subsequently, the magnetic attraction between the first magnet 62 and the second magnet 65 further strengthens the connection between the two, forming a dual guarantee of mechanical limiting and magnetic fixation. The above settings not only improve the positioning accuracy of the tea container lid 3, but also enhance its stability during operation, creating favorable conditions for the efficient transmission of ultrasonic energy.

[0033] Please see Figure 2 and Figure 4In some embodiments, the tea container 4 includes a hollow guide portion 42, a lid-fitting edge 41 surrounding the top edge of the guide portion 42, a raw material placement portion 43 integrally formed with and communicating with the bottom of the guide portion 42, and a snap-fitting edge 44 integrally formed with the raw material placement portion 43 and surrounding its edge; the lid-fitting edge 41 abuts against the lower surface of the pot lid 1, and the snap-fitting edge 44 is separable from the tea container lid 3; the peripheral wall of the raw material placement portion 43 is provided with filter holes 431. The lid-fitting edge 41 allows the top of the tea container 4 to make surface contact with the pot lid 1, improving the sealing performance of the lid; with the cooperation of the snap-fitting edge 44, the bottom of the tea container 4 is connected to the tea container lid 3, and the top of the tea container 4 is connected to the pot lid 1, which can effectively limit the displacement of the tea container 4, making it stably located in the inner cavity of the pot body 2, and ensuring that it remains vertical during vibration. Furthermore, after opening the lid 1, the overlapping edge 41 allows the user to easily reach into the upper part of the tea container 4 and remove it from the teapot body 2. Additionally, since the filter hole 431 is located on the raw material placement section 43 and not on the guide section 42, raw materials placed above the guide section 42 can smoothly fall into the raw material placement section 43 without leaking into the teapot body 2. In practical applications, the raw material placement section 43 is located above the ultrasonic generator 5, where the cavitation effect is strongest, allowing the raw materials above the ultrasonic generator 5 to be extracted quickly through high-frequency vibration. The snap-fit ​​edge 44 allows the tea container lid 3 to be separated, facilitating the removal and separate cleaning of the tea container 4 after use and reducing residual stains.

[0034] Please see Figure 3 and Figure 4In some embodiments, the edge of the upper surface of the tea container lid 3 is provided with multiple locking blocks 31 extending towards the center of the tea container lid 3. Each locking block 31 is used to clamp the snap-fit ​​edge 44. A snap-fit ​​clearance groove 32 is formed between any two locking blocks 31 to allow the snap-fit ​​edge 44 to enter. The multiple locking blocks 31 extending towards the center on the edge of the upper surface of the tea container lid 3 form a surrounding clamping structure, with their spacing adapted to the snap-fit ​​edge 44 extending outward from the edge of the tea container 4. The snap-fit ​​clearance groove 32 between any two locking blocks 31 provides an initial entry channel for the snap-fit ​​edge 44, ensuring that the tea container 4 can be quickly aligned during installation. When the tea container 4 is held and the snap-fit ​​edge 44 is pressed against the surface of the tea container lid 3, the snap-fit ​​clearance groove 32 can guide the snap-fit ​​edge 44 to accurately fall into the preset position, avoiding misalignment or jamming during installation. Once the snap-fit ​​edge 44 reaches the designated position through the snap-fit ​​clearance groove 32, the tea container 4 is pushed towards the center of the tea container lid 3. The snap-fit ​​edge 44 then enters the clamping area between multiple locking blocks 31 from the snap-fit ​​clearance groove 32. The enclosed space formed by the inner sides of the multiple locking blocks 31 perfectly matches the shape of the snap-fit ​​edge 44. Mechanical locking is achieved by the lateral compression of the snap-fit ​​edge 44 by the locking blocks 31. This clamping structure can restrict the displacement of the tea container 4 in the circumference, ensuring that the tea container 4 and the tea container lid 3 fit tightly together, and will not loosen or fall off even during ultrasonic vibration. The above structure requires no additional locks or tools; installation can be completed simply by inserting and pushing. To disassemble, pull the tea container 4 in the opposite direction to allow the snap-fit ​​edge 44 to retract into the snap-fit ​​clearance groove 32 for separation. While ensuring connection stability, it greatly improves operational convenience and meets the needs of frequent tea container retrieval and placement in daily use.

[0035] Please see Figure 2 and Figure 4 In some embodiments, the guide portion 42 is an inverted truncated cone, and the raw material placement portion 43 is a cylinder. The inverted truncated cone design of the guide portion 42 results in a large diameter inlet at the top of the guide portion 42, 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 43. The cylindrical design of the raw material placement portion 43 eliminates dead zones for raw material accumulation, ensuring even distribution, sufficient extraction, and easy cleaning of the tea storage compartment 4.

[0036] Please see Figure 3 and Figure 4In some embodiments, a second mounting groove 33 is provided in the inner cavity of the tea container cover 3. A sealing and noise-reducing adhesive 34 is provided in the second mounting groove 33, and a slot 35 is formed in the sealing and noise-reducing adhesive 34. The edge of the ultrasonic generator 5 is located in the slot 35. Specifically, the tea container cover 3 consists of an upper cover and a lower cover. The ultrasonic generator 5 separates the inner cavity of the tea container 4 and the tea container cover 3. During assembly, the edge of the ultrasonic generator 5 is inserted into the slot 35 of the sealing and noise-reducing adhesive 34, and then the sealing and noise-reducing adhesive 34 and the ultrasonic generator 5 are placed together in the second mounting groove 33. Finally, the upper cover and the lower cover are closed, and the upper cover and the lower cover are sealed and fixed by welding. The sealing and noise-reducing adhesive 34 further weakens vibration transmission and reduces noise during the operation of the extraction pot. The slot 35 is used to fix the edge of the ultrasonic generator 5, improving the stability of the ultrasonic generator 5 and reducing vibration deviation; moreover, the sealing and noise-reducing adhesive 34 can enhance the sealing performance of the inner cavity of the tea container cover 3 and help protect components such as the second magnet 65.

[0037] Please see Figure 3 and Figure 4 In some embodiments, the ultrasonic generator 5 includes an isolation plate 51 (stainless steel isolation plate) with its edge located in the slot 35, and a ceramic transducer vibrating plate 52 fixedly disposed on the lower surface of the isolation plate 51. The ceramic transducer vibrating plate 52 converts electrical energy into high-frequency vibration, which is efficiently transmitted to the liquid and raw materials above through the stainless steel isolation plate 51. 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 51 has advantages such as hardness and corrosion resistance, which can extend the service life of the extraction pot, while also blocking the liquid from the inner cavity of the tea container lid 3, protecting the internal components.

[0038] Please see Figures 1-4In some embodiments, the base 7 includes an upper shell 71 and a lower shell 72 that overlap each other. A circuit board 81 is disposed between the upper shell 71 and the lower shell 72. A terminal 82 is disposed in the inner cavity of the tea chamber lid 3. The terminal 82 achieves electrical connection between the ceramic transducer vibrator 52 and the circuit board 81 through a contact 83 disposed on the upper shell 71. The upper shell 71 has a power port 84, and a power connection port 85 is disposed in the power port 84. The power connection port 85 is electrically connected to the circuit board 81. When the tea chamber lid 3 is placed at the bottom of the pot body 2 and accurately aligned by the positioning mechanism 6, the terminal 82 in the inner cavity of the tea chamber lid 3 will make close contact with the contact 83 on the upper shell 71, forming an electrical connection path. This path transmits the electrical energy and control signals output by the circuit board 81 to the ceramic transducer vibrator 52, driving it to generate high-frequency vibration and providing energy for the extraction process. The contact design between terminal 82 and contact 83 relies on the precise positioning of positioning mechanism 6 to ensure stable conduction after each installation, reducing energy transmission loss or equipment failure caused by contact deviation. In addition, the power port 84 in the upper shell 71 is equipped with a power port 85, which is electrically connected to the circuit board 81 and serves as the connection hub between the base 7 and the external power supply. When the power port 85 is connected to the mains power, the electrical energy is rectified and transformed by the circuit board 81 into voltage and current that meet the operating requirements of the equipment, and then transmitted to the ultrasonic generator 5 through the cooperation of contact 83 and terminal 82.

[0039] Please see Figure 1 In some embodiments, a handle 22 is provided on the side wall of the vessel body 2. The handle 22 provides a gripping fulcrum, making it easy to lift the vessel body 2 and preventing slippage caused by hand contact with the vessel body 2 when pouring or moving the liquid. In addition, it can also isolate the hand from direct contact with the vessel body 2, reducing the irritation to the hand from the low-temperature cold extract.

[0040] Please see Figure 1 In some embodiments, the lid 1 is also provided with a handle 11. The handle 11 provides a gripping fulcrum, making it convenient for the user to hold the handle 11 and apply upward force to open the lid 1.

[0041] In summary, this invention integrates the tea chamber 4 and the ultrasonic generator 5 onto the tea chamber lid 3. The tea chamber lid 3 not only serves as the support and positioning function of the ultrasonic generator 5, but also works with the ultrasonic generator 5 to achieve integrated material extraction by sealing the bottom of the tea chamber 4. At the same time, it shortens the transmission path of ultrasonic energy, reduces energy loss and improves extraction efficiency while ensuring the convenience of the split design.
