Household soy milk machine on the market has two kinds now: a kind of for heating, play beans, slurrying, boiling all and control with the set time program.This shortcoming is: soya-bean milk quality, mouthfeel difference are bigger, and cause electrothermal tube to stick with paste pipe sometimes easily.Passed through technological improvement afterwards, another kind of soy bean milk making machine has occurred: this soy bean milk making machine is provided with temperature sensor, and its operation principle is to utilize temperature sensor that the work overall process of whole soy bean milk making machine is carried out intelligent program control.Therefore, in the installation process of soy bean milk making machine, to install respectively temperature sensor.And when cleaning, also to clean respectively electrothermal tube and these two parts of temperature sensor.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, a kind of composite electric heating tube that both can temperature control also can be used for heating is provided, and this composite electric heating tube process technology is simple and easy to realize mass, simple installation, can increase work efficiency, help the reduction of soy bean milk making machine cost.
A kind of composite electric heating tube, comprise the electric heating body, the wire-wound heating wire, the built-in wire-wound heating wire of electric heating body and fill the magnesium powder after carry out the draw and handle, the lead end of electric heating body is provided with fixed cover, the lead end that it is characterized in that described electric heating body is provided with two eduction rods, two ends with the wire-wound heating wire link to each other respectively, the cecum of described electric heating body is connected with metal tube one end by insulated connectors, metal tube built-in temperature sensor and heat conductive insulating medium, the metal tube other end also is provided with fixed cover, terminals, the lead-in wire at temperature sensor two ends links to each other with the terminals of metal tube.
Described temperature sensor is a thermistor, and described heat conductive insulating medium is an epoxy resin.
Described insulated connectors connects as one electric heating body and metal tube by thread connecting mode.
Described insulated connectors connects as one electric heating body and metal tube by welding manner.
The material of described insulated connectors is resistant to elevated temperatures insulating material.
Described electric heating body and insulated connectors, metal tube external diameter are identical.
The beneficial effects of the utility model:
Here, described heat conductive insulating medium is the good non-powder class megohmite insulant of heat conductivility, so the processing of metal tube does not just need to carry out draw PROCESS FOR TREATMENT.
The metal tube of described built-in thermistor and electrothermal tube can be processed separately, substep is made.The electrothermal tube processing technology is constant, still adopts built-in wire-wound heating wire, carries out the technology of the draw behind the filling magnesium powder, and the electric heating internal diameter of tube body behind the draw is consistent with the metal tube internal diameter.The metal tube of built-in thermistor is manufactured separately, and perfusion or fill heat conductivility good insulation performance medium again is as epoxy resin etc.Insulated connectors can be made as screw connection structure, and metal tube and electric heating body are connected as one; Insulated connectors also can connect as one metal tube and electric heating body by welding manner or bonding way, polishes processing then.Because what fill in the metal tube of built-in thermistor or pour into is non-powder class material, so do not need to carry out the draw, to thermistor and the no any destruction of lead-in wire, processing technology is simple, and high conformity, cost can not increase yet.
Simultaneously, because the existence of insulated connectors, guaranteed that temperature sensor can normally measure the temperature of liquid, and accurately transmitted temperature signal, the anhydrous performance detection that can realize simultaneously.In addition, when carrying out the assembling of soy bean milk making machine complete machine, only need a compound heating tube is installed, need not refill temperature sensor, reduced by an operation, help the reduction of cost, the simplicity of installation and operating efficiency improve.Because this scheme has reduced by a cleaning part, so make the head of soy bean milk making machine look more succinctly, also reduce simultaneously the difficulty of cleaning.
