The filtered air enters the air filter 102 through the external air connecting pipe 107 for the second filtration. After entering the main body fixing part 100 after filtration, it is sterilized by the ultraviolet short-wavelength LED sterilization module 111 under the drive of the rotating fan blade 104, which can more effectively remove impurities in the air. The coffee maker can filter out odors, peculiar smells and tiny particles to ensure that the air entering the coffee machine is pure, thus avoiding peculiar smells in the air affecting the original aroma of the coffee and making the coffee taste purer. The filtered air is heated by the ceramic heating resistor 112, and the maximum control temperature is 1000°C. The coffee sprayed through the coffee diversion nozzle 113 is fully in contact with the high-temperature air when sprayed upward from the bottom through the coffee diversion nozzle 113, so that more uniform heating can be achieved, avoiding local overheating or insufficient heating, and making the overall temperature of the coffee more consistent. The air is heated by the ceramic heating resistor 112 to heat the coffee, and no moisture is produced, thereby ensuring the best taste of the coffee and improving the quality of the coffee.

[0038] Further, such as Figure 1-Figure 9 As shown, a sensor fixing part 121 is fixedly installed below the heating duct heat preservation part 129 and outside the coffee heating air duct 115, and a temperature sensor 120 is fixedly installed on the sensor fixing part 121; the temperature sensor 120 is fixedly installed on the high temperature protection cover 114, and the high temperature protection cover 114 is fixedly installed on the coffee heating air duct 115 and outside the heating duct heat preservation part 129; a coffee slow flow nozzle 117 is fixedly connected to one end of the coffee heating air duct 115 away from the coffee diversion nozzle 113, and a coffee nozzle cover 116 is fixedly installed outside the coffee slow flow nozzle 117;

The coffee flows into the coffee slow flow nozzle 117 through the coffee heating air duct 115, and the coffee slow flow nozzle 117 prevents hot coffee from splashing and scalding.

[0040] Furthermore, if Figure 1-Figure 9 As shown, one end of the conduit 118 away from the coffee diversion nozzle 113 is fixedly connected to a coffee tank 127, and the coffee tank 127 is fixedly mounted on the device body 3. A coffee injection port 124 is fixedly mounted on the upper end of the device body 3, and the coffee injection port 124 is fixedly connected to the coffee tank 127;

A coffee cup placement net 4 is fixedly installed below the electronic control display panel 2. The device control circuit device 128 is electrically connected to the ARM main control circuit and the PID control temperature program circuit control through the electronic control display panel 2. The PID control principle is to subtract the measured output temperature c(t) from the set input temperature r(t) to obtain the deviation temperature e(t) and input it into the PID controller. After the corresponding proportional, integral, and differential algorithms are calculated, the PID control calculation result is output as a signal u(t) to control the ceramic heating resistor 112. The temperature sensor 120 detects the temperature c(t) of the ceramic heating resistor 112, forming a temperature control closed-loop structure, wherein the expression of the deviation e(t) is: e(t)=r(t)-c(t). Then, the PID controller is used to calculate the output u(t):

[0042] Among them, K p , T i , T d are the proportional coefficient, integral time constant and differential time constant respectively. After Laplace transformation of the above formula, we get its transfer function form; The PID temperature control program starts the heating function. At this time, the electronic control display panel 2 supplies power to the ceramic heating resistor 112 and the coffee heating air duct 115 and starts the heating function. According to the set heating time, the PID temperature control method starts from the maximum heating power and gradually reduces the heating power. The temperature sensor 120 detects the temperature value of the ceramic heating resistor 112. The maximum control temperature is 1000°C, which means that rapid heating is achieved and the heating function can be quickly reduced.

[0043] like Figure 1-Figure 9 As shown, the principle of the intelligent gas-heated coffee steam machine provided in this embodiment is as follows: by operating the servo motor 108 to form a negative pressure inside the cavity of the main body fixing part 100, the air is sucked into the filter cover 126 through the outside for the first filtration, and the filtered air enters the air filter 102 through the external air connecting pipe 107 for secondary filtration. After entering the main body fixing part 100 after filtration, it is sterilized by the ultraviolet short-wavelength LED sterilization module 111 driven by the rotating fan blades 104, which can more effectively remove impurities, odors and tiny particles in the air, ensure the purity of the air entering the coffee machine, avoid the odor in the air affecting the original aroma of the coffee, and make the coffee taste purer. The filtered air is heated by the ceramic heating resistor 112, and the maximum control temperature is 1000°C. For the coffee sprayed through the coffee diversion nozzle 113, the coffee is fully in contact with the high-temperature air when it is sprayed upward from the bottom through the coffee diversion nozzle 113, which can achieve more uniform The heating can avoid local overheating or insufficient heating, so that the overall temperature of the coffee is more consistent. The air is heated by the ceramic heating resistor 112 to heat the coffee, and no moisture is produced, which ensures the best taste of the coffee and improves the quality of the coffee. The electronic control display panel 2 is electrically connected to the ARM main control circuit and the PID control temperature program circuit control of the equipment control circuit device 128. The PID control principle is to subtract the measured output temperature c(t) from the set input temperature r(t) to obtain the deviation temperature e(t) and input it into the PID controller. After the corresponding proportional, integral and differential algorithm calculation, the PID control calculation result output signal u(t) is used to control the ceramic heating resistor 112. The temperature sensor 120 detects the temperature c(t) of the ceramic heating resistor 112, forming a temperature control closed-loop structure, wherein the expression of the deviation e(t) is: e(t)=r(t)-c(t), and then the output u(t) is obtained by calculation using the PID controller: Among them, K p , T i , T d are the proportional coefficient, integral time constant and differential time constant respectively. After Laplace transformation of the above formula, we get its transfer function form; The PID temperature control program starts the heating function. At this time, the electronic control display panel 2 supplies power to the ceramic heating resistor 112 and the coffee heating air duct 115 and starts the heating function. According to the set heating time, the PID temperature control method starts from the maximum heating power and gradually reduces the heating power. The temperature sensor 120 detects the temperature value of the ceramic heating resistor 112. The maximum control temperature is 1000°C, which means that rapid heating is achieved and the heating function can be quickly reduced. The heated coffee flows into the coffee heating air duct 115 through the overflow hole 119 for secondary preheating. The final coffee temperature can be controlled more accurately to ensure that each cup of coffee reaches the ideal drinking temperature. It flows into the coffee slow flow nozzle 117 through the coffee heating air duct 115 to prevent hot coffee from splashing and scalding.
