[0002] Brewing has a long history and has driven the development of tea sets, tea ceremony, tea art and tea culture. The teapot in the tea set is an important tool for brewing. The famous one is the purple clay teapot. Teapots have a very long history and there are many types. With the development of science and technology, teapots have also undergone many changes. They can be heated by electric heating and other methods. At the same time, more and more temperature control devices are also integrated. The existing electric teapots use electric heating wires as heating elements. Generally, the electric heating wires are set in the base of the teapot. After power is turned on, the teapot is placed on the base to heat the beverage; there are also electric teapots that use induction cookers as heating elements. This type of electric teapot uses the principle of electromagnetic heating to heat the iron-containing metal at the bottom of the teapot to heat the beverage.

[0003] With the continuous development and progress of science and technology, people have developed a brewing pot that can automatically control parameters such as concentration, temperature, and brewing time according to the type of beverage, which greatly improves the user experience.

[0051] Example 1

[0052] like Figure 1-5 As shown, an embodiment of the utility model provides an intelligent brewing kettle, including a base 20, a kettle body assembly 10, and a kettle cover body 30, wherein the kettle body assembly 10 is arranged on the base 20, and a handle assembly 40 is arranged on the kettle body assembly 10, and a display and control assembly 60 is arranged on the upper part of the handle assembly 40; a detection assembly 80, a main control circuit board 70 and a temperature control coupler 25 are arranged in the base 20, and the detection assembly 80 is arranged corresponding to the kettle body assembly 10, and a tea basket lifting mechanism 50 is also integrated in the kettle body assembly 10, and the display and control assembly, the detection assembly 80 and the tea basket lifting mechanism 50 are connected to the main control circuit board 70.

[0053] like Figure 4 , 5 As shown, a spout assembly 90 is also provided on one side of the kettle body assembly 10 . Specifically, the spout assembly 90 includes an outer spout 91 and a threaded inner spout 92 . The outer spout 91 and the threaded inner spout 92 are cooperated and fixed in the mounting hole of the side wall of the kettle body 11 .

[0054] Optionally, a spout sealing ring 93 is provided at the connection portion between the mounting hole on the side wall of the kettle body 11 and the threaded inner spout 92 .

[0055] like Figure 1 , 4 As shown, the kettle body assembly 10 includes a kettle body 11, a kettle bottom plate 14 arranged at the bottom of the kettle body 11, a heating device 15 is arranged in contact with the kettle bottom plate 14, and a water level sensor 12 is also arranged on one side wall of the kettle body 11, and the water level sensor 12 is connected to the main control circuit board 70. The constant temperature of the beverage can be set through the main control circuit board 70. When the temperature is lower than the constant temperature of the beverage, the heating device heats the beverage to keep the beverage at a suitable temperature.

[0056] Specifically, the kettle body 11 is a container formed by a transparent glass peripheral wall, or a container made of non-metallic materials such as ceramics and tempered glass.

[0057] Specifically, the water level sensing device 12 is a flexible PCB board that is attached to the outer wall of the kettle body 11, and metal diaphragms, preferably copper diaphragms, are evenly arranged on the flexible PCB board; when in use, first, the corresponding capacitance value of each metal diaphragm when the kettle body 11 is free of liquid is obtained, and the capacitance value data at this time is stored in the main control circuit 70 board as a reference reference capacitance value; a single or multiple copper diaphragms have an inherent parasitic capacitance Cp (also called self-capacitance) relative to the negative pole of the power supply, and similarly, there is an inherent parasitic capacitance Cp (also called mutual capacitance) between every two copper diaphragms. Then, the corresponding capacitance value of each copper diaphragm when there is liquid in the kettle body is detected, and compared with the reference base capacitance value of each copper diaphragm when there is no liquid before. In the case of self-capacitance, when the height of the liquid in the kettle body 11 reaches the height of the external copper diaphragm, the capacitance will change from Cp to Cp' (i.e., Cp'=Cp+Cx), and the position state of each copper diaphragm can be determined by judging the size of capacitance Cx; while in the case of mutual capacitance, when the height of the liquid in the kettle body 11 reaches the height of the external copper diaphragm, the capacitance will change from Cp to Cp' (i.e., Cp'=Cp+Cx), and a signal is transmitted through one copper diaphragm, while the other copper diaphragm receives the signal, and the main control circuit board 70 performs capacitance conversion, and judging the size of capacitance Cx can determine the position state of each copper diaphragm. Therefore, when the main control circuit board 70 detects the capacitance change of each copper diaphragm, the main control circuit board 70 performs internal calculations to calculate the current liquid level.

[0075] Optionally, the light source 810 is an LED light board, and the photosensor 811 can be a light intensity sensor or a CCD sensor. The CCD sensor is a silicon-based multi-channel array detector that can detect ultraviolet, visible and near-infrared light. Because it is a highly sensitive semiconductor device, it is suitable for analyzing weak Raman signals. In addition, the CCD detector allows multi-channel operation (the entire spectrum can be detected in one acquisition), so it is very suitable for detecting Raman signals. CCD detectors are generally one-dimensional (linear) or two-dimensional (planar) arrays, and the array is composed of thousands of independent detector elements (also called pixels). Each element generates an electric charge when it is acted upon by light - the stronger the light and the longer the action time, the more charge is generated. Finally, the readout electronic component draws the charge out of the pixel, so that each charge is read out and measured. In an ordinary Raman spectrometer, Raman scattering is first dispersed by a diffraction grating and then projected onto the long axis of the CCD array. The first pixel detects the low-wavenumber starting signal of the spectrum, the second pixel detects the signal at the next spectral position, and so on. The last pixel will detect the high-wavenumber terminal signal of the spectrum.
