There are shortcomings such as firing rate is slow, the thermal efficiency is low again in existing small-sized direct-heating type electric heater.As Chinese utility model 200320129677.2 disclosed a kind of " electric heater ", its heating tube is a quartz glass tube, is coated with one deck resistance heated film at the quartz glass tube outer surface, by the resistance heated film water in the heating tube of flowing through is heated.The manufacturing cost of resistance heated film is higher relatively, thereby and the difficult size of current adjusting temperature of adjusting; Heating tube does not have heat-insulation layer outward, easily dissipated heat.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of heat fast, security is good, the thermal efficiency is high, simple in structure, quick electric water heater that cost is low.
The technical scheme in the invention for solving the above technical problem is: this electric heater comprises heating tube, heating tube is that outer surface scribbles the heating layer quartz glass tube, its design feature is also to be provided with protection tube, protection tube is a quartz glass tube, heating tube is positioned at protection tube, the sealed at both ends terminal that is connected with of heating tube and protection tube, and form a cavity between heating tube and the protection tube, be respectively equipped with water inlet and the delivery port that is connected with heating tube on two terminals; Heating layer on the heating tube outer surface is the heating graphite coating, and the two ends of heating graphite coating are connected to electrode, is provided with Thermal Cutoffs in the cavity between heating tube and protection tube, and power outlet and electrode, Thermal Cutoffs constitute series loop.
The utility model is equipped with the metal drop bar on a terminal therein, and the metal drop bar is positioned at heating tube, and the metal drop bar links to each other with ground wire by earthing screw.
The utility model is equipped with temperature sensor on a terminal therein, and temperature sensor is positioned at heating tube.
Electrode described in the utility model is a spring, and two springs are set in the two ends of heating tube.
The utility model also is provided with insulating tube outside protection tube.
The utility model also is provided with insulating tube outside protection tube.
The utility model compared with prior art, have following beneficial effect: 1, with quartz glass tube as heat-generating pipe, outside heat-generating pipe, be covered with the heating graphite coating, by adjusting the thickness of heating graphite layer, regulate resistance, reach time of required heating-up temperature with setting, and the heating graphite coating is a kind of conductive heat-resistant coating, its cost is low, heating effect good, high temperature resistant manufacturing and processing cost are low; 2, be connected to electrode at the two ends of heating graphite coating, power outlet and electrode, Thermal Cutoffs are constituted series loop, when running into the empty condition of overhigh temperature of burning, when reaching the fusing point of Thermal Cutoffs, blown fuse, the loop disconnects, the heating graphite coating stops heating, reach overheated automatic protection functions, eliminate safe hidden trouble, security performance is good; 3, also be provided with the insulating tube of making for fire proofings such as the protection tube of quartz glass tube and sponges outside heating tube, protection tube plays the effect of safeguard protection, avoids the user to touch, and insulating tube then plays the effect of insulation, to improve the thermal efficiency, energy savings; 4, use spring as electrode, can increase the contact area of electrode and heating graphite coating, because the electric conductivity of graphite is lower than metallic conductor, be again to be overlying on the heating tube surface, so can there be the uneven situation of heating, and spring is a metallic conductor, increases the contact area of metallic conductor and heating graphite layer, can remedy the defective of graphite aspect electric conductivity; 5, firing rate is fast, i.e. heating after the energising, plug and play, do not need prior heat tracing, be energy-saving product, heating 15ml water to 75 ℃ can reach 3 seconds the soonest, sustainable hot-water supply is widely used in the occasion that various facial tissues machines, small water heater, boiler etc. need the heating small amount of liquid; 6, simple in structure, volume is little, assembling is easy, power range is wide, DC, AC all can use, voltage range all can in 6V～220V.
Description of drawings
Fig. 1 is a cross-sectional structure schematic diagram of the present utility model.
The specific embodiment
Referring to Fig. 1, the utility model comprises heating tube 1 and protection tube 6, heating tube 1 and protection tube 6 are quartz glass tube, heating tube 1 is positioned at protection tube 6, and the sealed at both ends terminal 5 that is connected with the silica gel material of heating tube 1 and protection tube 6, terminal 5 is inserted between heating tube 1 and the protection tube 6, makes and forms a cavity 11 between heating tube 1 and the protection tube 6; Outside protection tube 6, also be surrounded by the insulating tube 8 of sponge material.Be respectively equipped with water inlet 4 and the delivery port 12 that is connected with heating tube 1 on two terminals 5.The outer surface of heating tube 1 is coated with heating graphite coating 2; the two ends of heating graphite coating 2 are set with the spring 3 as electrode tightly; be provided with 7, two springs 3 of Thermal Cutoffs, Thermal Cutoffs 7 and power outlet 9 in the cavity between heating tube 1 and protection tube 6 and constitute series loop.On a terminal 5 temperature sensor 10 is installed therein, and temperature sensor 10 is positioned at heating tube 1, is used to measure the water temperature in the heating tube 1, be connected with sensor lead 16 on the temperature sensor 10; On another terminal 5, metal drop bar 13 is installed, and metal drop bar 13 is positioned at heating tube 1, and metal drop bar 13 links to each other with ground wire 15 by earthing screw 14, is used for heated liquid ground connection in the heating tube 1, eliminate the potential safety hazard of getting an electric shock, improve security performance.
The material of insulating tube 8 also can be other fire proofings.
During use, connect power outlet 9, heating graphite coating 2 begins heating; water flows into from water inlet 4; delivery port 12 flows out, and the water that 2 pairs of heating graphite coatings are flowed through in the heating tube 1 heats, and protection tube 6 and insulating tube 8 play the effect of mechanical protection and insulation respectively.Water temperature in 10 pairs of heating tubes of temperature sensor 1 is controlled, and under the improper situation, temperature is too high in the pipe, when reaching the fusing point of Thermal Cutoffs 7, and blown fuse, the loop disconnects, and reaches overheated automatic protection functions.Simultaneously, metal drop bar 13 makes the water ground connection in the heating tube 1, reaches to avoid the function of getting an electric shock.
