Abstract
An electronic infrared burning prevention electromagnetic oven comprises mechanical components of a water kettle, an N C 555 control chip, a transformer, an electronic input counter, an electro-thermal coil, an infrared temperature sensor and a pressure sensor, which is characterized in that the D line of the N C 555 control chip is connected with the infrared temperature sensor, and the A line of the N C 555 control chip is connected with the pressure sensor. The electronic infrared burning prevention electromagnetic oven has the functions of automatic control of water temperature and no water burning prevention through providing signals to the N C 555 control chip by the A circuit of the pressure sensor and breaking the electro-thermal coil of a power supply on the B circuit to stop work by the N C 555 control chip when the pressure sensor senses no water left in the water kettle.
Description
Technical field
The utility model relates to a kind of instrument that brews of finished tea, is the infrared anti-burning electromagnetic oven of a kind of electronics concretely.
Background technology
At present, finished tea generally adopts boiling water to be used as the overwhelming majority that accounted for that tealeaves brews, this mechanism simple structure, but have obvious weak point: because long boiling water of time is lowered the temperature, the tea quality does not reach the quality requirement of tealeaves own, anhydrous dry combustion method etc.
The utility model content
The purpose of this utility model is to provide a kind of electronics infrared anti-burning electromagnetic oven, makes guaranteeing former brewing on the simple basis of tool configuration, also has the cooling of the water temperature of elimination, and anti-dry can be used as the infrared anti-burning electromagnetic oven of electronics of the instrument that brews of finished tea.
The utility model is realized with following technical scheme: the infrared anti-burning electromagnetic oven of this electronics mainly is made up of impounding kettle, NC555 control chip, transformer, electronics enter counter, electrically-heated coil, infrared temperature sensor, pressure sensor.It is characterized in that: the D circuit of NC555 control chip is connected with infrared temperature sensor, and the A circuit of NC555 control chip is connected with pressure sensor.At first impounding kettle is placed on above the infrared anti-burning electromagnetic oven of electronics, the power supply of the infrared anti-burning electromagnetic oven of electronics is connected with the civil power of 220V, after becoming the 12V electric energy, the transformer transformation supplies electric energy to the infrared anti-burning electromagnetic oven of electronics by red line and green line, the NC555 control chip is when receiving the setup parameter of electronics enter counter C circuit, the NC555 control chip provides electric energy electrically-heated coil heating work by the B circuit to electrically-heated coil, the water temperature of impounding kettle feeds back to the NC555 control chip through infrared temperature sensor D circuit, when water temperature conforms to the data of electronics enter counter input, the NC555 control chip stops the electric energy of B circuit, and electrically-heated coil quits work; When water temperature is lower than 3 ° of the setting values of electronics enter counter, the conducting B line electricity heat coil work once more of NC555 control chip, so circulation; When pressure sensor perceives impounding kettle when anhydrous, pressure sensor A circuit provides signal to the NC555 control chip, and the power supply electrically-heated coil that the NC555 control chip disconnects the B circuit quits work, and has realized the automatic control and the anhydrous anti-dry function of water temperature.
Compared with the prior art, the error of using the infrared anti-burning electromagnetic oven of this electronics can solve water temperature is big, influences drawbacks such as tea quality.
In sum, to solve the water temperature error big just because of the infrared anti-burning electromagnetic oven of this electronics has, thus the tea quality when promoting tealeaves and brewing.
