Abstract
The invention provides a liquid heater, and belongs to the technical field of electric heating. The liquid heater comprises a kettle for holding a liquid, an upper shell and a lower shell, wherein a heating disc is sleeved by a thermal insulating ring; a through hole is formed in the heating disc; a silica gel thermal insulating sleeve is arranged inside the through hole; a fixing bracket is sleeved by the silica gel thermal insulating sleeve; an NTC and an NTC fixing column are arranged inside the fixing bracket; the NTC is fixed on the NTC fixing column; a convex shoulder extends outside the NTC fixing column; a spring sleeves the part below the convex shoulder of the NTC fixing column; a micro switch is further arranged on the lower shell. Compared with the prior art, the liquid heater has the advantages that the service life of the NTC is prolonged, the energy is saved, and the like.
Description
Technical field
The present invention relates to electric-heating technology field, relate in particular to a kind of can the liquid heater of accurate temperature control.
Background technology
At present, on the market the temperature control of liquid heater many employings NTC (negative tempperature coefficient thermistor) as thermometric components and parts.Chinese invention patent 200920129568.8 discloses the fixture of a kind of NTC for the class small household appliances that generate heat, comprise NTC, pedestal, probe bracket, spring and PCB, NTC is arranged on probe bracket, probe bracket and pedestal are socketed, and are provided with spring between probe bracket and pedestal, and pedestal is arranged on PCB, and be reliably assemblied on PCB, make NTC under the action of the spring, be close to heater element dut temperature surface, with heater element dut temperature surface reliable contacts.This technical scheme well solves NTC fixation problem, but the operating ambient temperature ignoring NTC is unsuitable too high, when kettle water level is too low, or even when empty burning, the heat radiation of heat-generating disc directly can have influence on NTC, make NTC be in a higher environment temperature, affect performance and the life-span of NTC.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of liquid heater is provided.This liquid heater has advantages such as extending NTC service life, economize energy.
The technical solution adopted for the present invention to solve the technical problems is: a kind of liquid heater, comprises the kettle body of holding liquid, heat-generating disc, upper shell and lower house, the outer nested insulating collar of heat-generating disc, and heat-generating disc has a through hole, is provided with silica gel collet in through hole; Distinguished: fixed support is enclosed within silica gel collet, is provided with NTC and NTC fixed leg in fixed support, NTC is fixed on NTC fixed leg, extends a convex shoulder outside NTC fixed leg, and spring housing is below NTC fixed leg convex shoulder, and lower house is also provided with microswitch; Described microswitch is connected with heat-generating disc power supply.
The kettle body bottom periphery region contacted with NTC can be a recess.
The outer nested insulating collar of heat-generating disc, heat-generating disc has a through hole, and through hole should be arranged in the place of stow away from heat on heat-generating disc, is provided with silica gel collet in through hole, can the heat trnasfer of effective heat insulation heat-generating disc.Fixed support is enclosed within silica gel collet; Be provided with NTC and NTC fixed leg in fixed support, NTC is fixed on NTC fixed leg, makes NTC exceed the surface of heat-generating disc, extends a convex shoulder outside NTC fixed leg, and spring housing is below NTC fixed leg convex shoulder, and spring can make kettle body contact with NTC closely; Lower house is also provided with microswitch.When kettle body water level too low or unloaded time, under the effect of spring and microswitch, NTC fixed leg, by jack-up, meanwhile, cuts off heat-generating disc power supply, except extending NTC service life, can also economize energy.
The kettle body bottom periphery region contacted with NTC can be a recess.Its effect is when kettle body is positioned over desktop, this region can be avoided to be subject to pickup, to keep the good contact with NTC.

Detailed description of the invention
Below in conjunction with accompanying drawing, set forth specific embodiments of the invention further.
A kind of liquid heater, comprises the kettle body of holding liquid, heat-generating disc, upper shell and lower house, the outer nested insulating collar of heat-generating disc, and heat-generating disc has a through hole, is provided with silica gel collet in through hole; Distinguished: fixed support is enclosed within silica gel collet, is provided with NTC and NTC fixed leg in fixed support, NTC is fixed on NTC fixed leg, extends a convex shoulder outside NTC fixed leg, and spring housing is below NTC fixed leg convex shoulder, and lower house is also provided with microswitch; Described microswitch is connected with heat-generating disc power supply.
The kettle body bottom periphery region contacted with NTC can be a recess.
Claims (2)
1. a liquid heater, comprising: the kettle body of holding liquid, heat-generating disc, upper shell and lower house, the outer nested insulating collar of heat-generating disc, and heat-generating disc has a through hole, is provided with silica gel collet in through hole; It is characterized in that: fixed support is enclosed within silica gel collet, is provided with NTC and NTC fixed leg in fixed support, NTC is fixed on NTC fixed leg, extends a convex shoulder outside NTC fixed leg, and spring housing is below NTC fixed leg convex shoulder, and lower house is also provided with microswitch; Described microswitch is connected with heat-generating disc power supply.
