Abstract
The utility model discloses a safe type electric heating water bag which comprises a soft bag, heat conducting liquid in the soft bag, and a heat generating pipe soaked in the heat conducting liquid, wherein a switch device is arranged in the heat conducting liquid. The switch device is formed by that an upper contact terminal and a lower contact terminal are arranged in an elastic casing body. The upper contact terminal and the lower contact terminal are respectively provided with a pull rope conducting wire, the pull rope conducting wires are respectively fixed at the upper end and the lower end of the elastic casing body, pass through the elastic casing body and are electrically connected with the heat generating pipe, and the position of the pull rope conducting wires where the pull rope conducting wires pass through the elastic casing body is provided with a sealing member. The switch device of the structure has the advantages of simple structure and favorable leak tightness, and the electric heating water bag can be used safely.
Description
Technical field
This utility model relates to the electric hot-water bag field, especially a kind of safety electric hot-water bag.
Background technology
An electric hot-water bag great variety of models on the market now, as Chinese patent 03226065.2 disclose a kind of by name " temperature automatically controlled electric hot-water bag " wherein this utility model comprise the software bag, conducting medium liquid in the software bag, being soaked in intravital anelectrode of conducting medium liquid and negative electrode and power supply circuits thereof constitutes, the software bag is provided with liquid injection hole and piston thereof, be provided with the gauge tap of anelectrode or negative electrode and the conducting of conducting medium liquid heating in the software bag, gauge tap is that an insulation shell is fixed in the software bag, the other end is provided with backguy in the software bag of corresponding insulation shell, in the cavity that anelectrode or negative electrode place, the through hole that backguy is passed on the insulation shell is connected with the top plug of be locked anelectrode or negative electrode, the following plug and the cavity opening of anelectrode or negative electrode are adaptive, the described power line of stating anelectrode or negative electrode places in the housing of backguy, and power line passes top plug and is connected with anelectrode or negative electrode.There is following shortcoming in it: 1) gauge tap of this electric hot-water bag is made up of insulation shell, the intravital anelectrode of insulation shell and negative electrode, a plurality of parts, the through hole of crossing on the insulation shell is worn with the backguy that the top plug of be locked anelectrode or negative electrode is connected, with the adaptive anelectrode of cavity opening or the following plug of negative electrode, place power line in the backguy etc. a plurality of parts form, its complex structure damages easily; 2) because power supply and backguy are integrated, the through hole that backguy is simultaneously passed on the insulation shell is connected with the top plug of anelectrode or negative electrode, when backguy is moved, stay cord and through hole are easy to generate clearance, cause conducting medium liquid to enter in the insulation shell, sealing is poor, thereby make positive and negative electrode be in normally off, when heating, can not control the conducting liquid temperature, thereby make the conducting liquid temperature too high, cause user to scald easily, overlong time even whole electric heating bag is blasted, use dangerous, unreliable.
The utility model content
The purpose of this utility model is to address the aforementioned drawbacks, and provides a kind of simple in structure, safe and reliable electric warm water bag.
The technical solution of the utility model is: a kind of safety electric hot-water bag, comprise heat-conducting liquid in the software bag, software bag, be soaked in the intravital heat-generating pipe of conductive fluid, one switching device also is set in the heat-conducting liquid, described switching device is to be provided with upper and lower contact in the elastic shell, one stay cord lead respectively is set on the described upper and lower contact, described stay cord lead is separately fixed at the upper/lower terminal of elastic shell and passes elastic shell and is electrically connected with heat-generating pipe, and the stay cord lead place of passing described elastic shell place is provided with sealing member.Described elastic shell surface is corrugated.Also be provided with the upper and lower backguy of elastic shell in the described software bag, described upper and lower contact is respectively equipped with magnetic block.
The beneficial effects of the utility model are: because the upper and lower backguy of the stay cord lead that upper and lower contact connects and elastic shell is to separate separately, strengthened housing seal greatly, its structure is more simple and safe, and upper and lower contact is arranged in the insulation shell, do not contact with heat-conducting liquid, thereby be difficult for electric leakage, use safe and reliable.
Description of drawings:
Fig. 1 is this utility model structural representation.
Fig. 2 is the switching device structural representation.
Fig. 3 is that this utility model makes the sketch map that heats switching device state when finishing.
The specific embodiment
Shown in Fig. 1 to 2: a kind of safety electric hot-water bag, comprise software bag 1, heat-conducting liquid 2 in the software bag 1, be soaked in the heat-generating pipe 3 in the heat-conducting liquid 2, it is characterized in that, one switching device 4 also is set in the heat-conducting liquid 2, described switching device 4 is to be provided with in the elastic shell 5, following contact 6,7, on described, following contact 6, one stay cord lead 8 respectively is set on 7, described stay cord lead 8 be separately fixed at elastic shell 5 on, following two ends 9,10 and pass elastic shell 5 and be electrically connected with heat-generating pipe 3, stay cord lead 8 places of passing described elastic shell 5 places are provided with sealing member 11.Elastic shell 5 surfaces are corrugated.Also be provided with the upper and lower backguy 12,13 of elastic shell 5 in the software bag 1.Upper and lower contact 6,7 is respectively equipped with magnetic block 14.Because the stay cord lead that upper and lower contact 6,7 connects and the upper and lower backguy the 12, the 13rd of elastic shell separate separately, strengthened the sealing of housing 5 greatly, this structure is simpler, and upper and lower contact 6,7 is arranged in the insulation shell, do not contact with heat-conducting liquid 2, be difficult for electric leakage, use safe and reliable.When electric hot-water bag need add when lively, the upper and lower contact 6,7 of switching device 4 is in closure state, at this moment connect with the mains and just can heat electric hot-water bag, in the heating process, the 1 constantly expansion of software bag along with the rising of temperature, upper and lower backguy 12,13 is slowly tightened up, thereby elastic shell 5 is elongated, when reaching design temperature, will open upper and lower contact (showing) in 6,7 minutes, thereby disconnected power down source as Fig. 3, reach temperature automatically controlled purpose, and used safe and reliable.
