Abstract
A heater structure for an electric thermos bottle mainly comprises a refill body, a heater backing plate, a heater, an aluminum press plate and an outer press plate. The utility model is characterized in that the edge on the circumference of the bottom part of the refill body is projected; the heater backing plate, the heater, the aluminum press plate and the outer press plate are sequentially embedded on the bottom part of the refill body; 6 to 10 evenly distributed convex points are arranged on the circumference of the edge of the outer press plate; the outer press plate is welded to the bottom part of the refill body through the convex points. The heater structure has the advantages that the heater and accessories are pressed after one-time welding through the evenly distributed convex points arranged on the circumference of the edge of the outer press plate, so that the clearance between the heater and the refill is small and the evenness degree is high, thereby effectively improving the quality of products.
Description
Technical field
The utility model relates to a kind of electrical heat tracing container, particularly a kind of heater structure of electric hot water bottle.
Background technology
Present widely used electrical heat tracing bottle, electric hot water bottle all are to adopt built-in heater heating, add thermal effect and will be directly connected to the electrical heat tracing bottle for heater and inner bag contact condition, can the heat that heater produces effectively be delivered in the inner bag water and be closely related with heater and inner bag contact condition, and the structural relation of heater and inner bag is to the efficiency of heating surface of electrical heat tracing bottle.The frame mode of conventional fixed heater is to adopt the mechanical means that iron sheet clamps and thread compresses at present, adopting the method to be pressed into heater can cause between heater and the inner bag and produce the gap, the unbalanced poor thermal conduction that causes of contact-making surface, rely on artificial manual operations in addition, poor consistency, quality stability are also relatively poor, and heater need instantaneous being pressed into could effectively entirely contact under the situation in the inner bag bottom on big plane, thereby guarantee the heat conduction, reach the index of electric property.
Summary of the invention
The purpose of this utility model is exactly at the defective that exists in the prior art, and a kind of heater structure of electric hot water bottle is provided.The utility model mainly comprises: inner bag stack shell, heater backing plate, heater, aluminium pressing plate, outer plate, it is characterized in that edge, described inner bag stack shell bottom protrusion, one recessed plane is formed on inner bag stack shell bottom, heater backing plate, heater, aluminium pressing plate, outer plate are inlaid on the recessed plane, inner bag stack shell bottom successively, be provided with 6-10 equally distributed salient point around the edge of outer plate, 6-10 the salient point of outer plate through the edge is welded on inner bag stack shell bottom.
The utility model has the advantages that the equally distributed salient point that is provided with around heater and the annex edge by outer plate adopts disposable welding to be pressed into, the little flatness height in gap has effectively improved product quality between heater and the inner bag.

Fig. 3 perspective exploded view of the present utility model.
1 inner bag stack shell, 2 heater backing plates, 3 heaters, 4 aluminium pressing plates, 5 outer plates, 6 salient points
The specific embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing:
Referring to Fig. 1, Fig. 3, inner bag stack shell 1 adopts stainless steel material to make, protrude the edge, bottom, make inner bag stack shell 1 bottom form a recessed plane, heater backing plate 2, heater 3, aluminium pressing plate 4, outer plate 5 preface successively is inlaid in the bottom of inner bag stack shell 1, heater backing plate 2 adopts the aluminium plating zinc plate material, aluminium pressing plate 4 adopts the aluminium sheet material, outer plate 5 adopts the aluminium plating zinc plate material, be provided with 6-10 equally distributed salient point 6 around the edge of outer plate 5, referring to Fig. 2, the diameter of salient point 6 is 0.8-1.1mm, highly be 0.5-0.7mm, adopt capacitor discharge welding that 6-10 the salient point 6 of outer plate 5 through the edge is welded on the bottom margin of inner bag stack shell 1, by outer plate 5 aluminium pressing plate 4, heater 3, heater backing plate 2 is tightly pushed down.
Adopting the process characteristic of capacitor discharge welding is to utilize the electric capacity storage power and the instantaneous relase electric current, and the contact of concentrating big electric current the to pass welded piece heat that has a resistance reaches and welds effect simultaneously.The advantage of this technology is a firm welding, and solder joint oxidation point is little, and the operation that need not to polish directly enters next procedure, and the power and energy saving, the instantaneous power that this equipment is taken from electrical network is low, the power factor height, compare with equal weld force equipment, have only 1/7～1/10, so use cost is low.
Claims (2)
1. the heater structure of an electric hot water bottle, mainly comprise: inner bag stack shell, heater backing plate, heater, aluminium pressing plate, outer plate, it is characterized in that edge, described inner bag stack shell bottom protrusion, one recessed plane is formed on inner bag stack shell bottom, heater backing plate, heater, aluminium pressing plate, outer plate are inlaid on the recessed plane, inner bag stack shell bottom successively, be provided with 6-10 equally distributed salient point around the edge of outer plate, 6-10 the salient point of outer plate through the edge is welded on inner bag stack shell bottom.
