Instantaneous heating core

Abstract

The invention discloses an instantaneous heating core, belonging to a heater. Steam generated by the existing heating core contains water droplets which can cause cleaning effect, disinfection effect and decontamination effect to be worse and pressure released by the steam can not be controlled, thus affecting the use. In the invention, a heating element is arranged inside the inner space of a shell and a water inlet and a steam outlet are arranged on the shell. The invention is characterized in that the inner space of the shell is provided with a first vaporization cavity, a second vaporization cavity and a third vaporization cavity in sequence from the water inlet to the steam outlet, wherein the volumes of the first vaporization cavity, the second vaporization cavity and the third vaporization cavity increase in sequence. The instantaneous heating core of the invention can generate dry and high-temperature steam, and the steam does not contain water droplets, so that no water droplet can be converted into steam with decrement of the pressure when water supply is stopped. Release of the steam can be stopped instantaneously and instantaneous heat and instantaneous stop of the steam can be realized. The invention ensures the cleaning effect, the disinfection effect and the decontamination effect.

Description

Technical field [0001] The invention belongs to a heating device, in particular to an instant heating core for heating water to generate steam for cleaning, disinfection and decontamination. Background technique [0002] The Chinese invention patent with the patent number ZL02225164.2 and the authorized announcement number CN2543601Y (hereinafter referred to as patent document 1) discloses a "steam spray gun" technical solution, and the patent document 1 discloses the technical content of a "steam generator" In order to ensure the flow direction of water and steam and the separation of steam and water at a certain pressure and speed, the gap formed by the heating core 13 of the "steam generator" and the cavity of the shell 12 is the largest at the water inlet 10 of the generator , It gradually becomes smaller along the left and right circumferential directions of the cavity of the shell 12, so that the water entering the steam generator 3 is preheated, and the preheated water flo...
