Abstract
The utility model provides a collapsible fast water heater, belonging to an electric heating unit. The collapsible fast water heater comprises a bottle cap in which a fixed casing is installed, collapsible casings are sheathed in the fixed casing, the middle part of heating wires in the two casings are heating wire sections which are wound as spiral shapes, flexible water-proof insulative material sleeves are provided between the heating wires and the two casings, and a power cord is connected at the upper end of the heating wires. For the fast water heater, because of the existences of the collapsible casings and the heating wire section which are wound as spiral shapes on the heating wires, while in use, the length of the heating device can be adjusted according to the height of a thermos, so that the water in the thermos at the upper and lower parts can be heated at the same time, and consequently, the time for boiling the water can be reduced, and the electricity consumption can be saved under the condition of certain power of heating wires.
Description
Technical field
The utility model provides a kind of improved electric heater unit, especially a kind of immersion heater.
Background technology
Immersion heater adds the device of hot water as a kind of electricity consumption, and is simple in structure because of it, cost is low, easy to use being used widely.But the length of the heater block on the existing immersion heater (comprise heating wire and heating wire outer shell) is fixed, when being used on the highly different thermos, and can not be according to the length of the Height Adjustment heater block of thermos.As when being used on the high thermos, the water of the first half in this immersion heater heat hot water bottle, the water of its latter half can only lean on the heat conduction of the water of the first half just to be heated, cause the water in the thermos can not be very fast by boiled, be to prolong heating time, under the certain situation of heating wire power, caused the increase of power consumption.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of telescopic immersion heater is provided, and it can be according to the length of the Height Adjustment heater block of thermos.
The utility model is to realize like this, the telescopic immersion heater, it has bottle cap, fixed housing is installed in the bottle cap, be set with flexible shell in the fixed housing, the middle part of the heating wire in two shells is the heating wire section of spirally-wound, and flexible water proof insulating material sleeve is arranged between heating wire and two shells, and the upper end of heating wire is connected with power line.
Adopt the telescopic immersion heater of said structure, because the existence of the heating wire section of the spirally-wound on flexible shell and the heating wire, in use, can be according to the length of the Height Adjustment heater block of thermos, the water that upper and lower half in the thermos is divided is heated simultaneously, thereby reduced the boiled used time of water, under the certain situation of heating wire power, also just saved power consumption.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
Among the figure, the 1-shell that stretches, the heating wire section of 2-spirally-wound, 3-fixed housing, 4-heating wire, the 5-bottle cap, 6-insulating covering, 7-insulating case, 8-insulator foot, 9-binding post, the 10-insulating lid, 11-power line, 12-attaching plug, the flexible water proof insulating material sleeve of 13-.
Embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates structure of the present utility model and using method.
As shown in drawings, the telescopic immersion heater of the utility model, it has bottle cap (5), fixed housing (3) is installed in the bottle cap, be set with flexible shell (1) in the fixed housing, the middle part of the heating wire (4) in two shells is the heating wire section (2) of spirally-wound, and flexible water proof insulating material sleeve (13) is arranged between heating wire and two shells, and the upper end of heating wire (4) is connected with power line (11).
The upper end of described heating wire (4) is connected with power line (11) by binding post (9), and binding post has insulating covering (6) outward, is fixed with insulating case (7) between insulating covering and the fixed housing (3).Can realize the insulation between binding post and the fixed housing like this.
Be fixed with insulator foot (8) in described fixed housing (3) upper end, insulating lid (10) is installed on the insulator foot.Can play protective effect like this to the user.Can realize being connected by screw thread between insulating lid and the insulator foot.
The shape of the heating wire outside the heating wire section of spirally-wound is identical with heating wire on the existing immersion heater.The same with existing immersion heater, on bottle cap, also have air-vent, so that the hot gas that produces in the thermos is discharged.Flexible water proof insulating material sleeve can be made by glass fiber material.The end of power line can have attaching plug (12).
During use, can adjust the length of the heater block of the heating wire composition in fixed housing, flexible shell and two shells according to the height of thermos.When being used for high thermos, the shell that stretches can be extracted out downwards in fixed housing, the length of the heating wire section of the spirally-wound on the heating wire prolongs thereupon, the length elongation of heater block.When being used for short thermos, can be with the shell indentation in fixed housing of stretching, the contraction in length of heater block.Stretching of the heating wire section of the spirally-wound on the heating wire just as spring.Heater block is put into thermos flask, whole immersion heater is located thereby bottle cap is stuck in the bottle mouth position of thermos.Attaching plug is inserted in the supply socket, the electrothermal wire heating, the water in the thermos is boiled.
Claims (3)
1, telescopic immersion heater, it is characterized in that, it has bottle cap (5), fixed housing (3) is installed in the bottle cap, be set with flexible shell (1) in the fixed housing, the middle part of the heating wire (4) in two shells is the heating wire section (2) of spirally-wound, and flexible water proof insulating material sleeve (13) is arranged between heating wire and two shells, and the upper end of heating wire (4) is connected with power line (11).
2, telescopic immersion heater as claimed in claim 1, it is characterized in that, the upper end of described heating wire (4) is connected with power line (11) by binding post (9), and binding post has insulating covering (6) outward, is fixed with insulating case (7) between insulating covering and the fixed housing (3).
3, telescopic immersion heater as claimed in claim 1 or 2 is characterized in that, is fixed with insulator foot (8) in described fixed housing (3) upper end, and insulating lid (10) is installed on the insulator foot.
