[0096] like Figures 1 to 50As shown, the utility model provides an ultrasonic extraction pot, comprising:

[0097] The kettle 100 comprises a kettle cover assembly 1, a kettle body 2 and a kettle bottom assembly 3, wherein the kettle bottom assembly 3 comprises at least a kettle bottom shell 31, a heating bottom plate 32, a heating module 33, an ultrasonic generator 34 and a vibration plate 35, wherein the kettle bottom shell 31 is buckled on the bottom of the kettle body 2, the heating bottom plate 32 is sealed and embedded in the bottom of the kettle body, and the heating module 33 can heat the medium (water medium, tea leaves and other media that need to be heated or ultrasonically extracted or kept warm) in the kettle body 2 through the heating bottom plate 32 when power is turned on; the vibration plate 35 is sealed and embedded in the heating bottom plate 32, one end of the ultrasonic generator 34 is inserted in the vibration plate 35, the ultrasonic generator 34 can generate ultrasonic waves when power is turned on, and the vibration plate 35 transmits ultrasonic waves to cause the medium in the kettle body 2 to vibrate ultrasonically;

[0098] The base 200 includes a base body 4 for supporting the kettle 100. A control unit 5 is provided in the base body 4. The control unit 5 is connected to a power source. The heating module 33 and the ultrasonic generator 34 are electrically connected to the control unit 5. The control unit 5 is used to control the working states of the heating module 33 and the ultrasonic generator 34.

[0099] The working principle of the ultrasonic extraction pot of the utility model for rapid extraction: Ultrasonic extraction utilizes the strong cavitation effect, disturbance effect, high acceleration, stirring effect and other multi-level effects generated by ultrasonic radiation pressure to increase the frequency and speed of molecular movement of substances and increase the penetration of solvents, thereby accelerating the target components to enter the solvent and promoting the extraction.

[0100] The ultrasonic extraction pot of the utility model is provided with an ultrasonic generator 34, which is powered on to start the ultrasonic generator 34 to generate ultrasonic waves. The water medium quickly penetrates into the tea tissue under the multi-level effect of the ultrasonic wave, and the effective substances in the tea cells quickly diffuse to the solid-liquid tissue interface and dissolve in the water medium. Due to the existence of the concentration gradient at the solid-liquid tissue interface, the solute quickly and continuously diffuses into the water medium in the pot, that is, the effective substances in the tea quickly diffuse and dissolve into the water medium, thereby realizing the rapid extraction of the tea.

[0101] The principles of rapid extraction for cold and hot brews are as follows:

[0102] Hot brewing: Turn on the power to start the ultrasonic extraction pot, start "heating" and "extraction" to heat and ultrasonically extract the drinking water and tea leaves added to the pot body. The heating module 33 is responsible for heating, and the ultrasonic generator 34 is responsible for generating ultrasonic waves.

[0103] Cold extraction: Add cold water to the ultrasonic extraction pot and start "extraction" for ultrasonic extraction.

[0104] Keep warm: Keep the hot brewed tea at a specific temperature, which is set to a specific value in advance. Put the extraction pot on the base, start "keep warm" to enter the keep warm mode, and control the heating module 33 to heat and keep the extraction pot at a predetermined temperature. If the pot is not placed or taken away, the keep warm program is disconnected.

[0105] The utility model provides a set of ultrasonic extraction pot solutions, which use the ultrasonic extraction principle to achieve rapid extraction of tea leaves. The utility model has a heating function, which can achieve ultrasonic thermal extraction. At the same time, the heating function is optional, and the user can choose not to heat and directly add cold water for ultrasonic rapid extraction. The utility model can achieve the functions of rapid hot brewing and cold extraction of tea leaves on the same machine. At the same time, the solution can also achieve the insulation function through the heating module, and the tea soup can be kept warm at a specific temperature after the heating extraction is completed. This solution is convenient and easy to operate, and has contributed to more convenient tea drinking for users.

[0107] The temperature sensing probe 36 abuts against the bottom surface of the heating module 33 to detect whether the temperature of the heating module 33 has reached the target temperature and to control the temperature of the heating module 33. The control unit 5 supplies power to the temperature sensing probe 36. If the temperature sensing probe 36 detects that the temperature of the heating module has not reached the target temperature, it sends a signal to the control unit 5 to control the heating module 33 to continue heating. If the temperature sensing probe 36 detects that the heating module 33 has reached the target temperature, it sends a signal to the control unit 5 to control the heating module to stop heating.

[0108] Further, if Figure 2 , Fig.46 , Fig.47 , Fig.48 , Fig.49 , Fig.50 As shown, the control unit 5 includes a control electronic board 51, which is connected to an external power source through a power line 52, and a working program is pre-implanted in the control electronic board 51; the control electronic board 51 is electrically connected to a first power-connecting metal sheet 531 and a second power-connecting metal sheet 532.

As a good conductor of electricity, the conductive metal sheet transmits the current to the buttons, the temperature probe 36, and the heating module 33 of the control panel, thereby realizing the power circuit between the power supply, the control electronic board 51, the buttons, the temperature probe 36, and the heating module 33. When the operator removes the kettle 100 from the base 200, the first conductive metal sheet 371 and the second conductive metal sheet 372 are respectively disconnected from the corresponding power-connected metal sheet and the power is cut off, the power circuit is disconnected, and each function stops working.

[0112] Further, if Fig.36 , Fig.37 As shown, the control unit 5 also includes a control panel, on which at least a heating key 541, an extraction key 542, and a keep-warm key 543 are arranged, and the heating key 541, the extraction key 542, and the keep-warm key 543 are all electrically connected to the control electronic board 51, and the working programs pre-implanted in the control electronic board 51 include at least a heating program, an extraction program, and a keep-warm program, and pressing the heating key 541, the extraction key 542, and the keep-warm key 543 respectively triggers the start of the heating program, the extraction program, and the keep-warm program.

[0113] The heating program needs to feed back the temperature detected by the temperature sensor to the control electronic board to control the heating temperature and heating time of the heating module. The insulation program is similar to the heating program. The insulation temperature is lower than the heating temperature, and the insulation temperature is generally between 45 and 55°C. The extraction program mainly controls the working time and frequency of the ultrasonic generator. The ultrasonic generator working frequency and the default time of a single operation are pre-set, and the work will stop automatically after the time is up. The operator can also press the "extraction" button to terminate the extraction according to personal wishes.

[0114] In a specific embodiment of the utility model, there are three buttons in total. From the perspective of the ultrasonic extraction pot facing the operator, the three buttons are, from left to right, a "heating" button, an "extraction" button, and a "keep warm" button. The "heating" button is responsible for heating the drinking water to the target temperature. The "extraction" button is responsible for starting the ultrasonic generator to perform ultrasonic extraction on the drinking water and the tea leaves soaked in the drinking water. The "keep warm" button is responsible for keeping the extracted tea warm. The operator can choose the "heating", "heating" + "extraction", "extraction" without heating, and "keep warm" functions according to personal wishes.

[0115] When the operator performs hot brewing, first connect the external power supply through the power cord on the base to power on the base. Then, put an appropriate amount of drinking water in the kettle, put in tea leaves, cover the kettle cover assembly 1, and place the kettle 100 on the base to start hot brewing. It should be noted that when placing the kettle, ensure that the conductive metal sheet is in contact with the power-connected metal sheet and is energized, so that a power circuit is formed. At this time, press the "heating" key and the "extraction" key in sequence, and the ultrasonic extraction kettle will perform hot brewing ultrasonic extraction according to the program pre-implanted in the control electronic board. "Extraction" can be started at the same time as the heating function, or it can be started in the middle of heating or at the end of heating. The operator can decide according to the characteristics of different tea leaves. After the extraction is completed, the control automatically stops according to the established program. The operator can also press the "keep warm" key to keep the extracted tea soup warm according to personal wishes.

[0116] When the operator performs ultrasonic cold extraction, he directly adds cold water and tea leaves into the kettle and presses the "extraction" button to perform ultrasonic extraction. After the extraction is completed, the operation is stopped according to the program control.

The pot lid 11 is welded from stainless steel, and the silicone sleeve 12 is made of food-grade silicone. The silicone sleeve 12 is sleeved inside the pot lid 11, and a plurality of raised annular strips are evenly distributed from top to bottom on the outer surface of the silicone sleeve 12. The gaps formed between adjacent raised annular strips play a role in positioning the pot lid assembly when the pot lid assembly is covered on the pot body. The size of the pot lid matches the size of the water inlet of the pot body 2.

[0120] like Figure 2 , Figure 4 As shown, the kettle body 2 is formed by glass die casting or ceramic slip casting. In a specific implementation of the utility model, the kettle body 2 is a triangular cone as a whole, with a water inlet 21 at the top, and the kettle cover assembly 1 is inserted into the water inlet 21 and covered on the kettle body. The kettle body 2 has a water spout 22 and a handle 23, and the water spout 22 is connected to the inside of the kettle body 2.

[0121] A circular opening 24 is arranged at the bottom of the pot body 2, and an annular edge plane 25 is arranged along the circumference of the circular opening 24 at the bottom of the pot. An annular step surface 26 is connected between the annular edge plane 25 and the inner wall of the pot body. The heating bottom plate 32 is covered on the annular edge plane 25 and is flush with the annular step surface 26 after installation.

[0123] Further, if Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a first vibration disk mounting hole 320 is provided on the heating base plate 32, a second vibration disk mounting hole 330 connected to the first vibration disk mounting hole is provided on the heating module 33, the vibration disk 35 is embedded in the first vibration disk mounting hole and the second vibration disk mounting hole, and a sealing gasket 39 is provided between the vibration disk 35 and the second vibration disk mounting hole.

[0124] Further, if Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, the heating bottom plate 32 includes a heating circular plate 321 matching the circular opening at the bottom of the pot. The heating circular plate 321 is bent downward and inward at the circumferential edge and then vertically bent downward to form a shielding edge 322 arranged in a circumference. An annular plane is formed between the outer side surface of the shielding edge 322 and the outer edge surface of the heating circular plate 321. A circular opening 24 at the bottom of the pot body 2 is arranged. An annular edge plane 25 is arranged along the circumference of the circular opening 24 at the bottom of the pot. The annular plane overlaps the annular edge plane 25. A sealing edge strip 38 is arranged between the annular plane and the annular edge plane. A first vibration disk mounting hole (circular through hole) is arranged at the center of the heating circular plate 321 for the vibration disk 35 to pass through and contact the drinking water in the pot body 2, thereby ultrasonically vibrating the drinking water. A plurality of heating module fixing holes 323 are arranged on the bottom surface of the heating circular plate 321, which is located outside the circumference of the first vibration disk mounting hole.

[0125] Specifically, the heating circular plate 321 is a stainless steel circular plate processed by a sheet metal bending process, and the size of the circular plate matches the circular opening at the bottom of the kettle body. The circular plate cover is arranged on the annular edge plane at the bottom of the kettle body, and the top surface of the circular plate after installation is flush with the annular step surface of the kettle body.

[0126] Three stud holes protrude circumferentially around the first vibration plate mounting hole to form a heating module fixing hole.

[0127] Further, if Fig.32 As shown, the sealing strip 38 is an annular strip made of food-grade silicone. The sealing strip 38 is L-shaped and is designed to mimic the annular step of the kettle body. The sealing strip 38 is arranged on the annular step surface 26 of the kettle body. On the L-shaped outer surface of the sealing strip, the vertical surface and the horizontal surface are respectively provided with at least one annular protrusion structure 381, which is used to prevent the water in the kettle body from leaking from the installation gap between the kettle body and the heating bottom plate.

[0128] Further, if Fig. 9 , Fig.10 , Fig.11 , Fig.12As shown, the heating module 33 includes an aluminum alloy disc 331, and the bottom surface of the aluminum alloy disc 331 is provided with an annular channel 332 protruding downward and provided with a circumferential notch, and a heating copper tube 333 is passed through the annular channel 332, and both ends of the heating copper tube 333 are exposed in the annular channel and located in the circumferential notch; a downwardly extending annular structure is provided at the center of the aluminum alloy disc 331, and a second vibration disc mounting hole is provided at the center of the annular structure; a countersunk groove is provided downward on the top surface of the aluminum alloy disc 331, and a top end of the sealing gasket 39 is provided A circular sealing ring extending outward is provided, and the circular sealing ring is sealingly sunken in the countersunk groove; the aluminum alloy disc 331 is provided with screw insertion holes 334 which can correspond to the fixing holes 323 of each heating module, and the heating module 33 is connected to the heating circular plate 321 by screws penetrated through the screw insertion holes 334 and the heating module fixing holes 323; the bottom surface of the aluminum alloy disc 331 is also provided with a pot bottom shell connecting part 335 extending downward, and the heating module 33 is connected to the pot bottom shell 31 through the pot bottom shell connecting part 335.

[0129] In a specific embodiment of the present invention, the heating module 33 is made of aluminum alloy (aluminum alloy disc 331 and annular channel 332) and a heating copper tube 333 by integral die-casting. The heating copper tube is wrapped with aluminum material and arranged at the circumference of the back plane of the disc. The top surface of the aluminum alloy disc 331 is a plane. The size of the aluminum alloy disc 331 matches the size of the heating disc 321 of the heating bottom plate. After the heating module is fixed by screws, its top surface is tightly attached to the back (bottom) of the heating disc 321.

[0130] Specifically, a countersunk groove (counterbore) is provided at the center of the top surface of the aluminum alloy disc 331, which is a sealing gasket installation hole. The annular step surface of the countersunk groove is used to place the annular sealing ring (the disc shape at the top of the sealing gasket) at the top of the sealing gasket 39, and the annular sealing ring is clamped between the step surface and the bottom end surface of the heating base plate. The countersunk hole extends a section of annular structure in the direction of the hole depth, which is used for the installation of the vibration disk (the cylindrical rod at its bottom end). The cylindrical through hole wall at the bottom of the sealing gasket is clamped between the outer side surface of the cylindrical rod at the bottom of the vibration disk and the inner wall of the countersunk hole.

[0131] On the back side (bottom surface) of the heating module, three columnar holes are evenly protruded around the installation hole of the sealing gasket 39, which are screw insertion holes 334, corresponding to the heating module fixing holes 323 on the back side of the heating base plate, and cooperate with the heating module fixing holes to fix the heating module on the heating base plate.

[0132] On the back of the heating module, three cylindrical threaded holes are evenly protruded around the sealing gasket installation hole, and the cylindrical threaded holes and the screw insertion hole 334 share a circumference. A cylindrical ring is sleeved on the outer circumferential wall of the cylindrical threaded hole, respectively, to raise the cylindrical threaded hole. The sleeved cylindrical ring surrounds the cylindrical screw hole in the middle, and the inner diameter of the cylindrical ring is larger than the aperture of the cylindrical screw hole, and the whole is a countersunk threaded hole. The structure composed of the cylindrical threaded hole and the sleeved cylindrical ring is collectively called the pot bottom shell connection part 335.

[0133] Three cylindrical through holes are evenly protruded on the bottom surface of the pot bottom shell 31, and three cylindrical through holes with slightly smaller apertures are vertically protruded upward from the centers of these three cylindrical through holes, forming a cylindrical through hole with a small top and a large bottom as a whole, which is the countersunk screw insertion hole 319 of the pot bottom shell. The cylindrical through hole with a small top and a large bottom inside makes the outer side of the countersunk screw insertion hole 319 have a circle of circular ring platform, and a step difference is formed between the circular ring platform and the top surface of the countersunk screw insertion hole 319. When the heating module 33 is fixed to the pot bottom shell 31, the top end of the countersunk screw insertion hole 319 on the pot bottom shell 31 penetrates into the pot bottom shell connecting part 335 on the heating module 33, and the top surface of the pot bottom shell connecting part 335 abuts against the outer circular ring platform of the countersunk screw insertion hole 319. At this time, the depth of the top end of the countersunk screw insertion hole 319 penetrating into the pot bottom shell connecting part 335 is the height of the step difference. The countersunk screw passes through the countersunk screw insertion hole 319 from the bottom of the kettle bottom shell, extends into the kettle bottom shell connecting part 335, and fixes the kettle bottom shell 31 to the heating module 33 through threaded fitting, thereby fixing the kettle bottom shell 31 and the kettle body 2 together.

[0134] Further, if Fig.33 As shown, the sealing gasket 39 is made of food-grade silicone material. The shape of the sealing gasket 39 is a contoured design of the sealing gasket mounting hole on the heating module. The top of the sealing gasket 39 is a disc shape, and a circle of circular sealing rings are convexly provided near the circumference of the disc shape. When the sealing gasket 39 is installed into the sealing gasket mounting hole on the heating module, the disc shape at the top of the sealing gasket 39 is clamped between the countersunk annular step surface of the sealing gasket mounting hole and the bottom end surface of the heating base plate. Since the heating module is fastened to the bottom end surface of the heating base plate by screws, the circular sealing ring on the top disc shape of the sealing gasket is also pressed tightly against the bottom end surface of the heating base plate, and the interference fit of the circular sealing ring prevents the drinking water in the pot body from leaking through the installation gap between the top of the vibration plate 35 and the heating base plate.

[0135] A cylindrical through hole is suspended at the center of the sealing gasket 39. At least two annular sealing rings 391 are protruding from the inner wall of the cylindrical through hole, and at least two sealing rings are protruding from the outer wall of the cylindrical through hole. When the vibration disk is installed in the countersunk hole of the sealing gasket mounting hole on the heating module, the side wall of the cylindrical through hole of the sealing gasket is clamped between the outer side surface of the vibration disk and the inner side wall of the countersunk hole of the sealing gasket mounting hole. The vibration disk (extension rod 352) is inserted into the cylindrical through hole at the bottom of the sealing gasket with interference fit. The sealing rings on the inner and outer sides of the cylindrical through hole of the sealing gasket prevent the drinking water in the pot body from leaking through the installation gap between the cylindrical rod at the bottom end of the vibration disk and the wall of the sealing gasket mounting hole on the heating module.

[0136] Further, if Figure 2 , Fig.17 , Fig.18 , Fig.19 As shown, the vibration disk 35 includes a vibration disk 351 embedded in the first vibration disk mounting hole, and the vibration disk 351 is connected to an extension rod 352 that passes through the second vibration disk mounting hole. The end of the extension rod 352 away from the vibration disk is provided with a connecting blind hole inward from the end surface, and one end of the ultrasonic generator 34 is inserted into the connecting blind hole; the top surface of the vibration disk 351 is flush with the top surface of the heating bottom plate 32, and the vibration disk 351 is in contact with the medium in the kettle body 2 to transmit the ultrasonic wave generated by the ultrasonic generator 34.

[0137] Specifically, the extension rod 352 is a cylindrical rod structure, and a connecting blind hole (semi-through hole) with a major arc section is concavely arranged in the center of the bottom end surface of the cylindrical rod structure. The depth of the connecting blind hole extends to the bottom end surface of the vibration disk 351. The connecting blind hole is a vibration disk connecting hole, and the vibration disk 35 is fixed on the major arc platform corresponding to the top of the ultrasonic generator through the connecting blind hole by interference fit.

[0138] The vibration disc 351 overlaps the installed sealing pad 39, is exposed from the second vibration disc installation hole in the center of the heating bottom plate 32, and is flush with the top surface of the heating bottom plate 32. The vibration disc 351 is exposed from the second vibration disc installation hole and contacts the drinking water in the kettle body, and causes ultrasonic vibration of the drinking water in the kettle by transmitting the ultrasonic wave generated by the ultrasonic generator.

[0139] Further, if Fig.13 , Fig.14 , Fig.15 , Fig.16 As shown, the top of the ultrasonic generator 34 is provided with a plug-in boss 343 which can be inserted into the connecting blind hole through interference, and the cross-section of the connecting blind hole and the plug-in boss 343 is set in a superior arc; the plug-in boss 343 is inserted into the connecting blind hole through interference, thereby driving the vibration disk to vibrate ultrasonically.

[0140] A positioning cone 344 with an increasing diameter is provided on the side wall of the ultrasonic generator 34, and a positioning hole 345 for fixing is also provided on the side wall of the ultrasonic generator 34; the positioning hole 345 is a threaded hole; a first terminal 341 and a second terminal 342 are provided at the bottom end of the ultrasonic generator 34 for connecting the positive and negative power supplies.

[0141] Specifically, the ultrasonic generator 34 is a device capable of generating ultrasonic waves, and its working principle is based on the piezoelectric effect. The ultrasonic generator 34 is provided with piezoelectric material, a vibration system and a driving circuit. When powered on, the driving circuit applies an alternating voltage signal to the piezoelectric material. Due to the existence of the piezoelectric effect, when an electric field is applied, the piezoelectric material undergoes a volume change, thereby causing vibration.

[0142] Further, if Figure 2 , Fig. 20 , Fig.21 , Fig. 22 , Fig.23 As shown, a mounting seat 311 extending upward from the bottom surface is provided in the outer shell 31 of the bottom of the pot, a generator mounting hole is provided in the mounting seat 311, and the part of the ultrasonic generator 34 located below the positioning cone is provided in the generator mounting hole, and the positioning cone is supported on the top surface of the mounting seat 311; a penetration hole 312 is provided on the side wall of the mounting seat 311, the penetration hole 312 and the positioning hole 345 are provided correspondingly, and the ultrasonic generator 34 is fixed by screws penetrated in the penetration hole and the positioning hole; a threading hole 313 is also provided on the side wall of the mounting seat 311 for circuit routing to supply power to the ultrasonic generator.

[0143] Further, if Fig. 22 , Fig.23 As shown, a circular through hole is provided at the center of the inner bottom end surface of the kettle bottom shell 31, and a first circular ring 3141 is coaxially connected to the circular through hole, and the first circular ring 3141 and the circular through hole are connected by a circle of annular inclined surfaces; the radial inner side of the first circular ring 3141 is coaxially and spaced from the outside to the inside and the second circular ring 3142 and the third circular ring 3143 are sequentially arranged, and the first circular ring 3141, the second circular ring 3142 and the third circular ring 3143 are connected by a strip connecting piece; the radial inner side of the third circular ring 3143 is suspended with a kettle mounting portion 315, and the kettle mounting portion 315 is connected to the kettle mounting portion 315. The mounting portion 315 can be seated on the base body 4; a first annular gap 3161 is formed between the first ring 3141 and the second ring 3142, and a second annular gap 3162 is formed between the second ring 3142 and the third ring 3143. The first annular gap 3161 and the second annular gap 3162 are respectively the plug holes of the first conductive metal sheet 371 and the second conductive metal sheet 372. The first conductive metal sheet 371 is plugged into the first annular gap 3161, and the second conductive metal sheet 372 is plugged into the second annular gap 3162.

[0144] Specifically, Fig. 22 As shown, the bottom shell 31 of the kettle is a circular groove structure as a whole, and the diameter of the groove structure matches the diameter of the bottom port of the kettle body, so that the bottom shell 31 is installed on the kettle body 2 and forms a whole with the kettle body in appearance. The outer periphery of the circular groove structure is a smooth arc surface. A circle of reinforcing ribs are evenly arranged in an annular array on the inner side wall of the circular groove structure, which are the bottom shell reinforcing ribs 3171.

[0145] like Fig. 22 As shown, a second ring 3142 and a third ring 3143 are sequentially arranged from the top surface of the first ring 3141 to the center direction. The annular surfaces of the second ring 3142 and the third ring 3143 are coplanar and flush with the top surface of the first ring 3141. The second ring 3142 and the third ring 3143 are suspended at the center of the first ring. The first ring 3141 and the second ring 3142, and the second ring 3142 and the third ring 3143 are connected by four uniformly annular array strip connecting pieces.

[0146] like Fig.21 As shown, a small circular groove is suspended at the center of the third ring 3143 to form a kettle mounting portion 315 (kettle mounting groove). The outer bottom edge of the kettle mounting portion 315 is a circular inclined surface structure. When the kettle is placed on the base for heating and extraction, the kettle mounting portion 315 is just completely plugged into the base 200.

[0147] A cylindrical structure is protruded from the center of the inner bottom end surface of the small circular groove, forming a mounting seat 311 of the ultrasonic generator.

[0148] like Fig. 22 As shown, a number of reinforcing ribs are connected between the outer wall of the mounting seat 311 and the inner wall of the small circular groove (kettle mounting portion 315), which are the mounting seat reinforcing ribs 3172.

[0149] Since the kettle bottom shell 31 is fastened to the heating module 33, and the heating module 33 is fastened to the heating bottom plate 32, and since the heating bottom plate 32 is covered on the annular edge plane at the bottom end of the kettle body, the annular edge plane blocks and limits the heating bottom plate 32. Due to the tight pressing and fixing relationship between the heating bottom plate 32, the heating module 33 and the kettle bottom shell 31, the heating bottom plate 32 is fastened to the kettle body 2, thereby also realizing the fastening connection between the kettle bottom shell 31 and the kettle body 2.

[0150] Further, if Figure 2 , Fig.24 , Fig.25 , Fig.26 , Fig. 27As shown, a pot bottom bracket 30 is arranged in the pot bottom shell 31, and the pot bottom bracket 30 includes a bracket ring body 301 with an opening at the bottom end, and the bracket ring body is buckled on the inner bottom end surface of the pot bottom shell 31, and a body top through hole is arranged at the top of the bracket ring body 301, and open circular ring platforms 302 are arranged radially at intervals inside the body top through hole, and isolated circular ring structures 303 are arranged radially at intervals inside the open circular ring platforms 302, and a first fixed gap 3041 for fixing the first conductive metal sheet 371 is formed between the side wall of the body top through hole and the open circular ring platform 302, and a second fixed gap 3042 for fixing the second conductive metal sheet 372 is formed between the open circular ring platform 302 and the isolated circular ring structure 303; a curved triangular platform 305 is arranged on one side of the bracket ring body 301, and the curved triangular platform 305 is connected to the temperature sensing probe 36 through a snap clamp 306.

[0151] Specifically, the bottom bracket 30 and the conductive metal sheet (the first conductive metal sheet 371 and the second conductive metal sheet 372) are manufactured by integral injection molding, and are not assembled later. The conductive metal sheet is pre-embedded in the injection mold of the bottom bracket and co-injected to form an inseparable integral component. The entire bottom bracket 30 is covered on the top surface formed by the first circular ring 3141, the second circular ring 3142 and the third circular ring 3143 of the bottom shell 31.

[0152] Three cylindrical threaded holes are evenly arranged around the circular through hole on the bottom end surface of the bottom shell 31, which are the bottom bracket fixing holes 318. Their positions and sizes correspond to the three bracket screw through holes 307 on the bottom bracket 30. The countersunk screws extend into the bottom bracket fixing holes 318 on the bottom shell 31 through the bracket screw through holes 307, and are threadedly matched with the bottom bracket fixing holes 318 to fix the bottom bracket 30 on the bottom shell 31. After the bottom bracket 30 is installed, the isolated circular ring structure 303 at its center is sleeved around the mounting seat 311 at the bottom center of the bottom shell 31.

[0153] The aforementioned countersunk screw penetration holes 319 are arranged on the outer circle of the array of fixing holes 318 of the bottom support of the kettle.

[0154] Specifically, the support ring body 301 of the pot bottom support 30 is an inverted circular groove structure, and a circular through hole (body top through hole) is provided at the center of the top surface of the inverted circular groove. An open circular ring platform 302 with an opening is suspended at the center of the circular through hole. The open circular ring platform 302 is connected to the circular through hole through a small arc plane 309, and the small arc plane extends from the edge of the circular through hole through the opening of the open circular ring platform 302 until it intersects and coplanar with the inner side surface of the open circular ring platform. The top surface of the small arc plane is coplanar and flush with the top surface of the inverted circular groove. The top surface of the open circular ring platform is higher than the top surface of the small arc plane, and the bottom end surface of the open circular ring platform is coplanar and flush with the bottom end surface of the small arc plane, and is coplanar and flush with the inner side of the top surface of the inverted circular groove. An annular gap is formed between the open circular ring platform 302 and the circular through hole, which is the first fixed gap 3041.

[0155] An isolated circular ring structure 303 is suspended in the center of the open circular ring platform 302, and the isolated circular ring structure 303 is not connected to the open circular ring platform. An annular gap is formed between the isolated circular ring structure 303 and the open circular ring platform 302, which is the second fixed gap 3042. The isolated circular ring structure 303 is connected to the pot bottom bracket by injection molding by plugging into the second fixed gap 3042 with the second conductive metal sheet 372 to form a whole. The top end surface and the bottom end surface of the isolated circular ring structure 303 are respectively coplanar and flush with the corresponding surfaces of the inverted circular groove.

[0156] On the top surface of the support ring body 301, after the first conductive metal sheet 371 is inserted into the first fixed gap 3041 and is integrally injection molded with the bottom support 30, a plurality of strip-shaped reinforcing ribs are uniformly extended along the outer circumference of the first conductive metal sheet 371 until they terminate at the circumference of the support ring body 301. The reinforcing ribs are the support end face reinforcing ribs 3081. A plurality of supporting ribs are connected between the inner side surface of the top of the support ring body 301 and the inner circumferential wall, and the supporting ribs are uniformly arranged circumferentially along the axis, which are the support reinforcing ribs 3082.

[0157] On the top surface of the support ring body 301, near the circumference, there are three circular through holes arranged circumferentially around the center of the circle, which are support screw through holes 307, corresponding to the pot bottom support fixing holes 318 on the pot bottom shell 31. The countersunk screw passes through the support screw through hole 307 and extends into the pot bottom support fixing hole 318 on the pot bottom shell, and is threadedly matched with the pot bottom support fixing hole to fix the pot bottom support 30 on the pot bottom shell 31.

[0158] On the top surface of the bracket ring body 301, a curved triangular platform 305 is convexly provided on one side of the circumference. The side of the curved triangular platform 305 facing the center of the circle is a curved surface, and the top surface of the curved triangular platform 305 is a quasi-triangular plane 3051. A plurality of triangular reinforcing ribs 3052 are connected between the bottom end surface of the quasi-triangular plane and the circumference of the side surface of the undercut circular groove.

[0159] The quasi-triangular plane is provided with three snap-on clamps 306 for clamping the probe disc structure 361 of the temperature sensing probe 36 into the clamps and fixing it on the quasi-triangular plane. The top of the snap-on clamps 306 has an inclined surface, which facilitates the disc structure of the temperature sensing probe to slide in along the inclined surface and be clamped and fixed.

[0160] A circular groove is concavely provided on the quasi-triangular plane, which is the positioning hole of the temperature sensing probe 36. A positioning convex point is provided at the corresponding position of the bottom end of the probe disc structure 361. When the temperature sensing probe 36 is installed, it is inserted into the positioning hole of the temperature sensing probe by the positioning convex point for positioning. The positioning hole of the temperature sensing probe and the three buckle clamping claws are arranged circumferentially along the same circle, and the circumference matches the circumference of the probe disc structure.

[0161] Further, if Figure 2 , Fig.28 As shown, the conductive metal sheet is a pair, namely a first conductive metal sheet 371 and a second conductive metal sheet 372, which are connected as the positive and negative electrodes of the circuit respectively.

[0162] like Fig.28 , Fig.29 , Fig.30 , Fig.31 As shown, the first conductive metal sheet 371 is a first conductive circular ring structure with a plurality of bottom notches. The top surface of the first conductive circular ring structure extends outward along the circumference to be provided with a first terminal 3711 (a flat sheet with a circular through hole for connecting the power supply wire) for external electrical connection; the bottom end of the first conductive circular ring structure is provided with four strip notches in the circumferential direction, and the strip notches axially penetrate the bottom end of the circular ring structure. The strip notches are designed to avoid the strip connecting piece between the first circular ring 3141 and the second circular ring 3142 on the outer shell of the bottom of the pot. The first conductive metal sheet 371 is inserted into the first annular gap 3161 on the outer shell of the bottom of the pot, passes through the first annular gap 3161, and contacts and energizes the first power-connecting metal sheet 531 on the base 200. The first annular gap 3161 on the outer shell of the bottom of the pot is an intermittent annular gap, so when the first conductive metal sheet 371 is plugged in, the strip notch needs to avoid the strip connecting piece on the outer shell of the bottom of the pot.

[0163] The structure of the second conductive metal sheet 372 is similar to that of the first conductive metal sheet 371: the second conductive metal sheet 372 is a second conductive circular ring structure with a plurality of bottom notches, the second conductive circular ring structure is radially spaced and arranged inside the first conductive circular ring structure, and the bottom circumferential direction of the second conductive circular ring structure is provided with four strip-shaped notches penetrating the bottom end of the circular ring structure, and the strip-shaped notches are designed to avoid the strip connecting piece between the second circular ring 3142 and the third circular ring 3143 on the bottom shell of the pot. The top surface of the second conductive circular ring structure extends outward along the circumference to be provided with a second terminal 3721 (a flat sheet with a circular through hole, used for the connection of the power supply wire) for external electrical connection.

[0164] The second conductive metal sheet 372 is inserted into the second annular gap 3162 on the bottom shell of the kettle, passes through the second annular gap 3162, and contacts and energizes the second power-connecting metal sheet 532 on the base 200. The second annular gap 3162 on the bottom shell of the kettle is an intermittent annular gap, so when the second conductive metal sheet 372 is plugged in, the strip-shaped gap needs to avoid the strip connecting piece on the bottom shell of the kettle.

[0165] A top notch 3712 is provided at the top of the first conductive circular ring structure for insulating and passing through the second terminal 3721. The top notch 3712 corresponds to an opening of the open circular ring platform 302 and is used for the second terminal to pass through. It is a terminal passing hole of the second conductive metal sheet. Openings are provided on the side walls of the open circular ring platform 302 for insulating and passing through the first terminal 3711 and the second terminal 3721 respectively.

[0166] The second terminal 3721 passes through the opening of the open circular platform 302 of the bottom support of the pot and passes through the top notch 3712 on the first conductive metal sheet. Since the second terminal 3721 passes through the top notch 3712 on the first conductive metal sheet, in order to prevent the two conductive metal sheets from contacting and short-circuiting, an insulating sleeve 3722 made of plastic material is sleeved on the second terminal 3721.

[0167] Further, if Figure 1 , Figure 2 As shown, the base 200 is composed of a base body 4 and a control unit 5. The base body 4 includes a base shell 41, a base cover 42 and a power connection structure 43. The control unit 5 is mainly composed of a control electronic board 51, buttons (heating button 541, extraction button 542, keep warm button 543), and a power cord 52.

[0168] like Fig.48 , Fig.49 , Fig.50 As shown, the control electronic board 51 is disposed in the base housing 41 ; the base cover 42 is detachably connected to the bottom end of the base housing 41 .

[0169] like Fig.34 , Fig.35 , Fig.36 , Fig.37 As shown, the base shell 41 is a flat inverted bowl-shaped structure with an opening at the bottom, a circular flat surface at the top, and an arc-shaped circumference around it.

[0170] The inner side wall of the arc surface circumference of the base shell 41 is uniformly arrayed with a plurality of arc surface profile reinforcement ribs, which are the base shell reinforcement ribs 411. The bottom end of the base shell 41 is a circular opening, and the diameter of the circular opening matches the diameter of the base cover plate 42. The edge of the circular opening is a step-like structure, and the edge of the circular opening is a step edge.

[0171] A circle of annular plane is connected between the step edge and the bottom end of the arc surface of the base shell 41, which is the annular connection surface of the base. The annular gap space formed by the step edge is to accommodate the edge of the base cover when the base cover is installed. A circle of inclined surface structure is arranged on the step edge, which is the step edge inclined surface. The step edge inclined surface is to facilitate the inclined hook foot buckle of the base cover to slide and buckle on the base shell.

[0172] On the outer wall of the arc surface of the base shell 41, two runway planes are symmetrically and parallelly arranged about the central axis, one of which has a circular through hole, which is a power line insertion hole for connecting an external power supply to the control electronic board 51 of the ultrasonic extraction pot. The other is a control panel (key panel), on which three function buttons are arranged. The ultrasonic extraction pot faces the operator, and the buttons are heating button 541, extraction button 542, and insulation button 543 from left to right.

[0173] When the kettle 100 is placed on the base 200 for heating and extraction, the top end surface of the base shell 41 supports the bottom end surface of the kettle bottom shell 31, thereby supporting the entire kettle.

[0174] Further, if Fig.38 , Fig.39 , Fig.40 As shown, the base cover plate 42 is a circular plate-like structure. The diameter of the circular plate-like structure matches the opening diameter of the bottom end of the base shell 41. On the top surface of the base cover plate 42, a circular ring platform is protruded from the circumference to the center of the circle, which is a snap-on circular ring platform 422. Four inclined hook-foot snap-on structures 423 are arranged evenly in a circumferential direction on the top surface of the snap-on circular ring platform 422. The inclined hook-foot snap-on structures 423 slide along the inclined surface of the step opening of the base shell and snap onto the top surface of the step opening of the base shell. After the base cover plate is installed to the base shell, the bottom end surface of the base cover plate is flush with the bottom end surface of the base annular connecting surface. On the top surface of the base cover plate, four columnar threaded holes are protruded on the inner side of the snap-on circular ring platform, which are evenly arranged in a circumferential direction along the center of the circle, which are the fixing holes 421 for the control electronic board. The control electronic board fixing hole 421 corresponds to the limiting fixing hole 511 on the control electronic board 51. The countersunk screw passes through the limiting fixing hole 511 on the control electronic board into the control electronic board fixing hole 421 on the base cover 42 and fixes the control electronic board 51 to the base cover 42 through threaded engagement.

[0175] Further, if Fig.41 , Fig.42 , Fig.43 , Fig.44As shown, the power connection structure 43 includes a power connection bracket, which includes a bracket disc 430 arranged in the base shell 41, and a first bracket ring 431 extending upward is arranged on the bracket disc 430. The first power connection metal sheet 531 is fixed to the outer side of the first bracket ring 431 by integral injection molding, and the first conductive metal sheet 371 can be inserted between the first power connection metal sheet 531 and the first bracket ring 431; the second bracket ring 432 is radially spaced on the inner side of the first bracket ring 431, and the second power connection metal sheet 532 is radially spaced and sleeved on the outer side of the second bracket ring 432, and the second conductive metal sheet 372 can be inserted between the second power connection metal sheet 532 and the second bracket ring 432; the first power connection metal sheet 531, the first bracket ring 431, the second bracket ring 432, and the second power connection metal sheet 532 are arranged through the power connection structure through-hole.

[0176] The top surface of the base shell 41 (inverted bowl-shaped structure) is provided with a power connection structure through hole 413 (circular through hole) for the power connection structure 43 to pass through so that the power connection metal sheet provided thereon contacts with the conductive metal sheet for electricity.

[0177] The power connection metal sheets (the first power connection metal sheet 531 and the second power connection metal sheet 532) are manufactured by an integral injection molding process with the power connection structure 43. The power connection metal sheets are embedded in the injection mold of the power connection bracket and are co-injected to form an inseparable integral component.

[0178] The power connection bracket is a disc structure, and the bottom end surface of the disc structure is provided with three cylindrical holes along the circumference of the center of the circle, which are cylindrical limiting holes 433. The cylindrical limiting holes 433 correspond to the power connection structure fixing holes 412 on the base shell 41. On the inner side of the top surface of the base shell 41 (inverted bowl-shaped structure), three cylindrical threaded holes are provided in a uniform array around the circumference of the power connection structure through-hole, which are the power connection structure fixing holes 412. The cylindrical limiting holes 433 on the power connection bracket are sleeved on the power connection structure fixing holes 412, and the power connection structure is fixed to the inner side surface of the top surface of the base shell 41 by means of countersunk screws and the threaded engagement of the power connection structure fixing holes 412.

[0179] On the top surface of the bracket disc 430, a strip groove surrounds the outer side of the first bracket ring 431, which is a sealing ring installation groove 436. The first power-connecting metal sheet 531 is fixed around the outer periphery of the first bracket ring 431 through an integral injection molding process. The first power-connecting metal sheet 531 is inserted into the groove surface of the sealing ring installation groove. In the sealing ring installation groove, a sealing ring is installed close to the bottom end of the outer periphery of the first power-connecting metal sheet 531 to prevent water from leaking into the base from the installation gap between the power connection structure through hole on the base shell and the first power-connecting metal sheet 531.

[0180] The outer edge of the top surface of the first bracket ring 431 is chamfered to form an annular slope, which is the first bracket annular slope. When the kettle 100 is placed on the base 200 for heating and extraction, the first bracket annular slope avoids the first conductive metal sheet 371, which is conducive to the first conductive metal sheet 371 being plugged into the inner side of the first power-connecting metal sheet 531 for contact and power supply.

[0181] The top of the second bracket ring 432 is similar to the first bracket ring 431 , and is provided with a second bracket annular inclined surface, which facilitates the second conductive metal sheet 372 to be energized by contacting with the second power-connecting metal sheet 532 .

[0182] The bottom end of the second bracket ring 432 is provided with an annular inclined platform protruding upward along the inner side wall. When the kettle mounting part 315 on the kettle bottom shell is inserted and sunk into the second bracket ring 432 of the power connection bracket, the annular inclined platform in the second bracket ring 432 just supports the annular inclined surface at the bottom end of the kettle mounting part 315, and then together with the top end surface of the inverted bowl-shaped structure of the base shell, supports the entire kettle. At this time, the top end surface of the second bracket ring 432 just touches the bottom end surface of the second circular ring of the kettle bottom shell.

[0183] An arc-shaped strip through hole is concavely arranged on the outer side of the first bracket ring 431, on the groove surface of the sealing ring installation groove, and along the outer periphery of the first bracket ring, which is the contact plate through hole of the first contact metal sheet 531, and becomes the first contact plate through hole 434; the shape of the contact plate through hole matches the shape of the contact plate of the first contact metal sheet. The contact plate through hole is used for the contact plate of the first contact metal sheet to pass through the bottom end surface of the contact bracket, so as to be connected with the wire of the control electronic board.

[0184] An annular gap is formed between the first bracket ring 431 and the second bracket ring 432. An arc-shaped strip through hole is recessed on the bottom end surface of the annular gap, which is the contact plate through hole of the second contact metal sheet, and is formed as the second contact plate through hole 435. The shape of the contact plate through hole matches the shape of the contact plate of the second contact metal sheet. The contact plate through hole is used for the contact plate of the second contact metal sheet to pass through the bottom end surface of the contact bracket, so as to be connected with the wire of the control electronic board.

[0185] like Fig.45 As shown, the power-connecting metal sheet is a pair, divided into positive and negative electrodes, namely the first power-connecting metal sheet 531 and the second power-connecting metal sheet 532, which are respectively in contact with the conductive metal sheet to conduct electricity. The first power-connecting metal sheet 531 and the second power-connecting metal sheet 532 are integrally injection molded with the power-connecting bracket. The first power-connecting metal sheet 531 is located outside the first bracket ring 431, and the second power-connecting metal sheet 532 is located between the first bracket ring 431 and the second bracket ring 432. After the power-connecting metal sheet and the power-connecting bracket are integrally injected, only the power-connecting sheet passes through the bottom end surface of the bracket disc 430, and other parts of the power-connecting metal sheet do not pass through.

[0186] The bottom end of the first power-connecting metal sheet 531 is a ring-shaped structure, and the top end is connected to a ring-shaped bell-shaped structure. The ring-shaped bell-shaped structure is designed to facilitate the first conductive metal sheet 371 to be inserted into the inner side of the first power-connecting metal sheet 531 for contact and conduction when the kettle is placed on the base. At the bottom end of the first power-connecting metal sheet 531, an arc-shaped sheet with a circular through hole extends along the side wall of the ring-shaped structure, which is the power-connecting sheet of the first power-connecting metal sheet. The power-connecting sheet is connected to the control electronic board through a wire for power supply.

[0187] The second power-connecting metal sheet is similar in shape to the first power-connecting metal sheet, with a ring-shaped structure at the bottom and a ring-shaped bell-mouth structure at the top, and a power-connecting sheet of the second power-connecting metal sheet extending from the side wall of the ring structure to the bottom. The power-connecting sheet is connected to the control electronic board through a wire for power supply.

[0188] Further, if Fig.46 As shown, the control electronic board 51 is a rectangular plate structure with a circular opening in the center and circular through holes in the four corners. The central circular opening can avoid the power connection plate of the power connection metal sheet passing through the upper power connection bracket, so as to facilitate the connection between the power connection plate of the power connection metal sheet and the wire of the control electronic board. Fig.47 As shown, the circular through holes at the four corners are the limiting fixing holes 511 of the control electronic board 51, corresponding to the control electronic board fixing holes 421 on the base cover. The countersunk screws penetrate the control electronic board fixing holes 421 on the base cover through the limiting fixing holes 511 on the control electronic board, and the control electronic board 51 is fixed to the base cover 42 through threaded engagement.
