Vapor generator

Abstract

The invention relates to a vapor generator, in particular to a vapor generator used for generating substantial vapors, and belongs to the technical field of medical apparatus and instruments. The vapor generator comprises a boiler body; and a cavity is arranged in the boiler body, an air inlet, a water inlet and a vapor outlet are arranged at the upper end of the boiler body, a multi-ring heating wire is connected at the lower end of the boiler body, an inner ring of the heating wire is connected with a water level sensor, and an outer ring of the heating wire is connected with a liquid-expansion temperature control switch. The vapor generator is simple, compact and reasonable in structure and is not easy to be blocked, sterilizing quality is improved, and failure rate and maintenance rate are reduced; efficiency of the vapor generator is high due to adoption of the heating wire, and sterilizing time is greatly reduced; heat stored energy of the vapor generator is reduced, control of the vapor generator is sensitive when power is saved, and phenomena such as overshoot are avoided; safety performance is improved; and the vapor generator is easy to mount, and convenient to use and maintain.

Description

technical field [0001] The invention relates to a steam generator, specifically for generating a large amount of steam, and belongs to the technical field of medical equipment. Background technique [0002] At present, the structure and working principle of the common steam generators on the market are completely different from this design, and the common steam generators are composed of a steam generating device and a heating device. Among them, the steam generating device is designed with a spiral flow channel on two aluminum substrates, and the two aluminum substrates are combined into one, and the middle is sealed with a high-temperature sealing ring, and a heating rod and a temperature measuring device are installed on the other end of the aluminum substrate. When the heating rod works, the aluminum substrate generates a very high temperature. At this time, when water enters the flow channel inlet of the heated aluminum substrate, the flow channel outlet will generate s...

AI Technical Summary

Problems solved by technology

Due to the limitation of the flow channel, the flow channel is easily blocked by scale. Once the flow channel is blocked, the steam generator will not work.

In addition, since the sealing between the two aluminum substrates is realized by a rubber sealing ring, under the effect of long-term high temperature, the sealing ring is likely to fail to achieve the sealing effect due to aging, which increases maintenance work and other risks; at the same time, in order to generate saturation Water vapor can only work intermittently, so the efficiency of steam generation is not very high
