In order to achieve the purpose, the utility model adopts the technical scheme that:
an outer assembly of an outer coating liquid heater is provided with a tubular stainless steel shell, heat insulation cotton, a mica pipe and one or more outer coating liquid heaters connected in series from outside to inside; the two ends of the external coating liquid heater are respectively provided with a boss cylindrical water inlet head and a boss cylindrical water outlet head, and the boss cylindrical bottoms of the water inlet head and the water outlet head are buckled at the water inlet end and the water outlet end of the external coating liquid heater through sealing devices; the upper end of the boss cylinder of the water outlet head is provided with a detachable temperature sensor; a temperature control switch is arranged on the outer wall of the outer coating liquid heater close to the water outlet end; a screw tensioning device is arranged between the water inlet head and the water outlet head, the cylindrical steps of the bosses of the water inlet head and the water outlet head are respectively provided with an annular screw tensioning device fixing seat, and the screw tensioning devices are connected and tensioned with the two fixing seats through a plurality of connecting screws; and a protective seat is arranged outside each fixed seat and is buckled with the stainless steel shell.
Furthermore, the sealing device comprises a silica gel sealing ring arranged between the water inlet and outlet heads and the end of the outer coating liquid heater.
Further, sealing device still includes the snare and is in outer coating film liquid heater tube head outer wall have the stainless steel clamping ring and the O type fluorine rubber seal circle of external screw thread, the stainless steel clamping ring pass through the external screw thread with it is fixed to advance water head and go out the water head and screw, and make the stainless steel clamping ring passes through O type fluorine rubber seal circle with the silica gel seal circle compresses tightly.
Further, the screw tensioning device is provided with three connecting screws.
Furthermore, the external coating liquid heater is a nano superlattice electric heating tube with quartz glass as a base material.
When liquid flows through the nano superlattice electric heating tube through the water inlet, the nano superlattice electric heating tube starts to heat, heat is taken away from the water outlet by the liquid, the temperature sensor can accurately detect the temperature of outflow water, the temperature control switch can more accurately control the heating temperature of the superlattice electric heating tube, and the overtemperature safety protection effect is achieved; when the silica gel sealing rings at the water inlet and the water outlet of the superlattice electrothermal tube are invalid and leak water, the o-shaped fluorine rubber sealing ring continues to seal, so that water is prevented from leaking, and a second sealing protection effect is formed; the mica tube isolates the nano superlattice electric heating tube from an external metal component, and plays a role in protecting a heating film of the nano superlattice electric heating tube; the heat insulation cotton is wrapped between the mica pipe and the stainless steel shell, and most of the heat on the outer wall of the nano superlattice electric heating pipe is transferred to the liquid in the nano superlattice electric heating pipe through the heat insulation cotton, so that the heat is obviously isolated from being transferred to the stainless steel shell to be dissipated, and the energy-saving and heat-insulation functions are achieved; the stainless steel shell protects the nano superlattice electric heating tube from external impact and impact.
The utility model has the beneficial effects that: the external coating liquid heater assembly provided by the utility model has the advantages that the energy is saved when the flowing liquid is heated, the sealing effect is better, the safety and the reliability are better, and the heating temperature can be controlled more accurately. The integral structure has the characteristics of integration, small volume, energy conservation, double-sealing protection, accurate temperature control and the like, can be used as a core heating component of various household and commercial liquid heating equipment, and has wide market.
