Multi-module variable-frequency heating device

Abstract

The invention discloses a multi-module variable-frequency heating device which comprises a heating disc, a heat insulation plate and a stroke guide rod. A through hole penetrating through the heatingdisc body is formed in the middle of the heating disc, at least one groove is formed in the upper surface of the heating disc, electric heating wires are packaged in the grooves, the electric heatingwires are electrified and heated through binding posts, and each electric heating wire corresponds to two binding posts; a binding post installation hole penetrating through the heat insulation plateis formed in the heat insulation plate, a through hole is formed in the middle of the heat insulation plate, and a counter bore with the diameter larger than that of the through hole is formed above the through hole of the heat insulation plate. The end, provided with the external threads, of the stroke guide rod can penetrate through the through hole in the heating disc and a counter bore in theheat insulation plate in an up-down moving mode, and the through hole extends out of the heat insulation plate; the end, provided with the internal threads, of the stroke guide rod is sleeved with a spring, the bottom of the spring abuts against the bottom of the counter bore, the upper portion of the spring is sleeved with a gasket, the screw is installed on the internal threads of the stroke guide rod in a threaded mode to press the gasket on the spring, and the gasket is higher than the heating piece under the pressure-free condition. The device is simple in structure and convenient to use.

Description

Technical field [0001] The invention relates to the field of traditional Chinese medicine decoction preparation, in particular to a multi-module frequency conversion heating device for traditional Chinese medicine decoction preparation. Background technique [0002] As an excellent cultural heritage of the Chinese nation, Chinese medicine has received increasing attention in recent years. Traditional Chinese medicine preparations require patients to take them home and torture themselves, use ceramic containers, fill them with Chinese medicine and water, and heat them with charcoal fire. This method of decocting medicine is time-consuming and laborious, and it has not adapted to the fast-paced modern life. Therefore, in recent years, electric heating decoction methods have been developed. Electric heating decoction has high efficiency and large output. The quality of decoction is better than manual decoction. However, as the core component of the electric decoction machine, the ...
