Intelligent shell temperature control system of traditional Chinese medicine fumigation therapeutic apparatus

Abstract

The invention provides an intelligent shell temperature control system of a traditional Chinese medicine fumigation therapeutic apparatus, which comprises a power processing circuit, a keyboard control circuit, an LCD (liquid crystal display) displaying circuit, a voice and alarm circuit, a single chip microcomputer system circuit, an A/D (analog/digital) conversion circuit, a laser ranging sensor, an environment temperature sensor, a shell temperature sensor, a pot internal steam temperature sensor, a pot internal steam pressure sensor, an EPROM (electrically programmable read-only-memory) circuit, an optocoupler, a silicon controlled thyristor and an electric heating film. An embedded single chip microcomputer is utilized as a control core, by means of measuring pot internal steam pressure and temperature, heating of the electric heating film is controlled in a closed-loop manner, constant output flow of steam is guaranteed, the system sets steam contact temperature by the aid of a user keyboard according to a relational table of environment temperature stored by an EPROM, steam contact shell temperature and the distance from a steam outlet to the shell of the body of a user, an LCD displays the position and the contact temperature of the human body in real time, the human body is prompted to move so as to reach a proper distance in a voice manner, and when the contact temperature is over high and skin of the user is easy to be injured, the system alarms and cuts off a power source. The intelligent shell temperature control system is simple in structure, low in manufacturing cost, convenient in operation, stable in performance and high in intelligent degree.

Description

technical field [0001] The invention relates to a medical instrument, in particular to an intelligent body surface temperature control system for a traditional Chinese medicine fumigation treatment instrument. Background technique [0002] The therapeutic effect of traditional Chinese medicine fumigation is produced by the interaction between the heat energy of fumigation and the medicine loaded in the steam, and acting together on the body. The thermal effect dilates the capillary network on the surface of the affected area, which plays a role in dredging the air mechanism and connecting the blood vessels. The medicinal effect is achieved by the Chinese medicine particles escaped from the fumigation medicine acting on the body surface and absorbed into the body through the open vascular network. During the fumigation process of traditional Chinese medicine, the thermal energy and medicinal effect continue to act on the human body, which can dispel wind and dampness, promot...

AI Technical Summary

Problems solved by technology

However, the temperature provided by the traditional Chinese medicine fumigation treatment instrument in the prior art is displayed as the temperature of the liquid medicine, rather than the temperature of the steam that is in contact with the patient's body surface and plays a decisive role in the treatment.
