Medical baking lamp with automatic temperature control function

Abstract

The invention discloses a medical baking lamp with an automatic temperature control function. The medical baking lamp comprises a resistance wire load, a capacitor, an enhancing type field effect tube, a control circuit of a single chip microcomputer, and a rectifying circuit, wherein the rectifying circuit is connected with an alternating current circuit; the rectifying circuit comprises four rectifying diodes which are connected in a head-to-tail way; the anode end and cathode end of the capacitor are respectively connected with an anode and a cathode of the output end of the rectifying circuit; a first end of the resistance wire load is connected with the anode end of the capacitor, and a second end of the resistance wire load is connected with a drain electrode of the enhancing type field effect tube; a source electrode of the enhancing type field effect tube is connected with the cathode end of the capacitor, and a grid electrode of the enhancing type field effect tube is connected with the control circuit of the single chip microcomputer; the control circuit of the single chip microcomputer comprises a switch power source, a temperature sensor, an adjustable potentiometer, the single chip microcomputer, and a digital display tube; the switch power source is connected with the alternating current circuit, an anode of the switch power source is connected with the power source input end of the single chip microcomputer, and the cathode of the switch power source is connected with the grounding end of the single chip microcomputer. The medical baking lamp has the advantages that the temperature can be continuously and controllably adjusted, and the secondary burn injury to the skin due to overhigh temperature is avoided.

Description

technical field [0001] The invention relates to the field of medical roasting lamps, in particular to a medical roasting lamp with automatic temperature control. Background technique [0002] Now Chinese medicine is more and more favored and valued by people, and more and more patients choose Chinese medicine for treatment. As an auxiliary means of traditional Chinese medicine treatment, medical baking lamps are used very frequently. But now many hospital lamps still use the technical principle of the original resistance wire heating. The biggest problem in the use of this technology is that it cannot control the temperature of the patient's skin in real time. If the temperature is too low, it will not be able to achieve a good therapeutic effect. Burns burns. Therefore, there is an urgent need for a new type of medical baking lamp, which can detect the temperature of the patient's skin in real time, and automatically adjust the temperature according to the detected temper...
