The steam delivery pipeline and the steam outlet pipe are wrapped by heat insulation layers, and the bubble breaker 19 is arranged at the steam outlet to prevent a small amount of water from entering the steam outlet above the steam outlet when the water is boiled.
In this embodiment, the first temperature sensor 23 mainly functions to monitor the temperature in the negative pressure cooker, and the first pressure sensor is used to monitor the pressure in the negative pressure cooker; a second temperature sensor 10 is used to monitor the temperature inside the steam pressure equalisation tank and a second pressure sensor 11 is used to monitor the pressure inside the steam pressure equalisation tank.
The pressure balance tank 3 is also provided with a pressure release valve 16 for performing pressure release operation when the steam accumulation is excessive.
The heating unit 2 is an induction cooker or a heating wire which is external and is close to the side wall and/or the bottom surface of the negative pressure cooker, the side wall and the bottom surface of the negative pressure cooker are made of heat conducting materials, and the outer surface of the negative pressure cooker is made of heat insulating materials.
The bottom of the negative pressure cooker is provided with a washing port 21, a control valve is arranged on the washing port, and the washing port 21 and the inner side wall of the negative pressure cooker form an acute angle, so that the washing water can form a vortex in the negative pressure cooker for washing more conveniently.
In other embodiments, the pot body of the negative pressure pot is a double-layer structure, and the heating unit is a heat pipe or an electric heating wire arranged in the negative pressure pot.
The working principle is as follows: firstly, liquid medicine is injected into a negative pressure pot, then a first negative pressure fan and an electromagnetic valve are started, steam outlets on a pressure balance tank are also opened, the negative pressure pot is pumped into a required negative pressure environment, the steam outlets on the pressure balance tank are closed, then the liquid medicine begins to be heated, due to the fact that air pressure is reduced, the boiling point of the liquid medicine is reduced, vaporization temperature is reduced, a large amount of steam with medicine components is finally generated, due to the fact that the temperature is low, medicine properties of the medicine are protected, and the problem that the medicine is decomposed at high temperature and loses efficacy is effectively solved.
Steam gets into the steam pressure balance tank from steam outlet, steam delivery pipeline in, the steam pressure balance tank self-adjusting, steps up the operation through the tonifying qi, and the in-process that steps up can be followed the decline of temperature, and steam volume reduces, and after satisfying final required temperature, the steam outlet on the pressure balance tank is opened again, discharges steam and uses.
Because the temperature of the steam pressure balancing tank is reduced in the boosting operation process, a part of steam is inevitably lost and becomes water drops, therefore, a backflow pipe 20 is arranged at the bottom of the steam pressure balancing tank and is connected to the negative pressure boiler, the bottom end of the steam pressure balancing tank is obliquely arranged, an inlet of the backflow pipe is arranged at the lower side of the bottom end of the steam pressure balancing tank, and the opening and closing of the backflow pipe are controlled by a backflow valve, so that the backflow of liquid drops is realized.

The main purpose of adding the steam circulation pipeline 17 is to perform circulation heating when the negative pressure in the pressure cooker is strong, which causes excessive temperature drop and temperature does not meet the requirement, and the negative pressure is weakened and the temperature is increased along with the increase of the steam quantity, and after the negative pressure reaches the required negative pressure environment and temperature, the steam circulation pipeline is adjusted and used again according to the method in the embodiment 1.
In addition, when no steam is needed outside, the pipeline can be opened, the heat supply of the heating unit is reduced, the steam circulates in a relatively stable environment, on one hand, the problem that the whole equipment is completely closed and is relatively complex to restart is solved, on the other hand, the relatively stable temperature can be guaranteed, and when the steam is needed next time, the temperature can be adjusted to the needed temperature as soon as possible and output.
Example 3
The difference from example 2 is that: in order to improve the automation degree, a first pressure sensor in the negative pressure cooker is associated with the circulating valve and the first negative pressure fan, and the rotating speed of the first negative pressure fan and the opening and closing of the circulating valve are controlled according to the sensing pressure of the first pressure sensor, so that the pressurization and temperature increase or the pressure reduction and temperature reduction in the negative pressure cooker are realized.
That is to say, the whole cycle starting process is automated, once the pressure in the negative pressure cooker is too low or too high, the stable output of the steam is affected, and at the moment, the negative pressure cooker needs to be pressurized and heated or depressurized and cooled by means of a circulating pipeline.
Example 4
As shown in fig. 3, a liquid level sensor 22 is installed in the negative pressure cooker, the liquid level sensor 22 is associated with the dosing valve 5 of the dosing port, and the on-off of the dosing valve is controlled according to the sensing signal of the liquid level sensor to realize automatic dosing.
