Abstract
An automatic double-insulation dry-burning-preventive constant temperature electric heater relates to the technical field of liquid heaters. The technical scheme of the electric heater includes that an electric heating filament is arranged inside a metal tube, insulating filling materials are arranged between the metal tube and the electric heating filament, a metal outer tube is arranged outside the metal tube, and a magnesium oxide insulating layer is filled between the metal tube and the metal outer tube. By adopting double-layer insulation, the electric heater can improve the safety performance of heating devices and lead a product for heating liquid to be greatly improved in insulation effect.
Description
Technical field
The utility model relates to liquid heat device technical field.
Background technology
Existing liquid heat device be in metal tube by insulation filling material closely packed heating wire because product is used for liquid heat, most liquid has conductivity, has directly caused the defective of its poor safety performance so the list of this liquid heat device insulate.In addition,, be prone to dry combustion method because product does not have the automatic constant-temperature protection mostly, phenomenons such as excessive high temperature, the potential safety hazard of existence is big.
The utility model content
The utility model purpose is to design a kind of two insulation anti-dry automatic constant-temperature electric heaters with double insulation effect.
The utility model is provided with heating wire in metal tube, the insulation filling material is set between metal tube and the heating wire, outside described metal tube metal outer pipe is set, and fills the magnesium oxide insulating barrier between described metal tube and metal outer pipe.
Owing to adopt double hyer insulation can improve the security performance of heating components and parts, make product be used for the liquid heat insulation effect and improve greatly.
Produce for convenience, further improve the insulating properties of product, the utility model also is provided with the magnesium pipe between described metal tube and heating wire.
Also can in described magnesium pipe, fill the magnesium oxide insulating barrier.
The inner in metal outer pipe is provided with thermostat, and the signal output part of described thermostat is connected with the power circuit of described heating wire.
The utility model adopts the work of thermostat control heating wire, and when dry combustion method occurring, or temperature is when being higher than design temperature, and the signal that thermostat collects is a localized hyperthermia, can make the power circuit dead electricity of heating wire immediately, stops heating.Can have and realize anti-dry and the purpose that fluid temperature is controlled.
