Abstract
The utility model relates to a rod-shaped electric heater with a plug cover, which comprises a rod-shaped electric heater, wherein, the plug cover which is made of insulating material is fixed at the tail end of the electric heater. The utility model is characterized in that the periphery of the plug cover is provided with screw thread which forms screw seal connection with the mouth of an applied liquid container. The root part of the screw thread of the plug cover is provided with a seal washer for enhancing the effect of sealing, the tail end of the plug cover can be provided with a recessed part in which contact pins that are connected with a positive and a negative poles of the electric heater are arranged, and the tail ends of the contact pins are lower than the edge of the recessed part so as to reduce the contact probability between hands and the contact pins. The utility model has the advantage that the plug cover forms screw seal connection with the mouth of the applied liquid container, and consequently can be applied to the liquid containers which need to be sealed as hot water bags, hot water cups, etc. The arranged positive and negative contact pins at the tail end of the plug cover can be powered on, in the state of heating, by connecting with a power cord which is provided with a corresponding socket body, and the power cord is only required to be pulled out in the state of non heating (when the hot water bag is used).
Description
Technical field
The utility model relates to a kind of electric heater, particularly a kind of bar-shaped electric heater that heats in the liquid that is immersed in.
Background technology
Existing bar-shaped electric heater is the most common with " immersion heater " that be commonly called as, by making the water heating in direct insertion thermos and the submergence water within it, because thermos all is vertical placement at ordinary times, therefore the gag that is positioned at " immersion heater " afterbody is similar to thermos cork, neither hermetically-sealed construction between itself and the thermos bottleneck, just because of this, existing " immersion heater " just can't be applied to similar hot-water bottle to be needed in the horizontal liquid container like this; On the other hand, the electrothermal tube of existing " immersion heater " is directly drawn lead to plug, so its heated liquid container just is limited in the zone at lead place, and the existence of lead is just as a tail, under non-heated condition, both influenced the normal use of liquid container, also influenced attractive in appearance.
Summary of the invention
Technical problem to be solved in the utility model is the bar-shaped electric heater that a kind of modified model band gag is provided at above-mentioned prior art present situation, and it and applied liquid container can constitute sealing.
Another technical problem to be solved in the utility model provide a kind of under non-heated condition no conductor strip gag bar-shaped electric heater.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the bar-shaped electric heater of band gag includes a bar-shaped electric heating body, its afterbody is fixed with the gag of an insulation material, it is characterized in that described gag periphery is provided with screw thread, form thread seal with its applied liquid container oral area and be connected.
Sentence at the thread root of described gag that to be provided with a seal washer be good, with the enhanced leaktightness effect; Described gag tail end can have a recessed position, is provided with the contact pin that links to each other with the positive and negative electrode of described electric heating body respectively in it; Described pin end is good with the edge that is lower than described recessed position, to reduce the probability that hand contacts with contact pin;
Described electric heating body is good to adopt the PTC heating element, can be made of the PTC heating component of housing and Qi Nei.
Compared with prior art, advantage of the present utility model is that the applied liquid container oral area of its gag and its forms thread seal and is connected, therefore can be applied to the liquid container that hot-water bottle, hot water cup etc. need sealing, and the setting of the both positive and negative polarity contact pin of gag tail end, under heated condition, can be attached thereto and switch on by a power line that is provided with the respective socket body, under non-heated condition (in use) as hot-water bottle as long as then take out power line, thereby convenient the use.

Fig. 2 is the structure cross-sectional schematic of the utility model embodiment.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the bar-shaped electric heater of band gag includes a bar-shaped electric heating body 1, PTC heating component 12 by housing 11 and Qi Nei constitutes, its afterbody is fixed with the gag 2 of an insulation material, the periphery of gag 2 is provided with screw thread 21, thread root is provided with a seal washer 4 (can be integral piece with gag 2), and liquid container applied with it (as hot-water bottle and so on, not showing among the figure) oral area forms thread seal and connects; The tail end of gag 2 has a recessed position 22, is provided with in it respectively and the distance of described electric heating body, the contact pin 3 that negative pole links to each other, and the end of contact pin 3 is lower than the edge at described recessed position 22.
