Referring to Fig. 1-2, a kind of novel electric heating bag, including being equipped with the bag body 1 of heat preservation liquid, being arranged in the intracorporal electric heating of bag Device, the power input socket 5 being mounted in bag body, bag body is by the hot-forming gained of the soft waterproof layer of two panels, wherein a piece of or two The soft waterproof layer of piece is the side wall 11 by injection molding and along bag body profile with arc transition.It is provided by the utility model Novel electric heating bag allows bag body to keep various shapes due to the side wall with certain altitude, such as disc, ellipse Shape, cartoon animals outline shape etc., the liquid even if in bag will not make its boundary profile disappear flowing.Will it is wherein a piece of or Two panels bag body injection molding, then two panels bag body hot pressing is formed to closed hot-water bag cavity.

Soft waterproof layer is made by rubber material or plastic material.Such as rubber injection mold or PVC injection molding are made symmetrically Upper and lower two panels bag body part, bag body part at the middle and upper levels is equipped with socket aperture, for installing power input socket 5.Due to two panels bag body Part is injection molded with side wall, therefore has certain chamfered shape, can realize common circle, ellipse by injection mold The shapes such as shape, or special cartoon shape pattern, promote final product quality class.Pass through the sealing inside sealed silicone bag body Cavity is filled with the liquid medium for transmitting heat, and liquid medium expands when being in predetermined temperature or the total volume and liquid of vaporization The normal volume that body medium is under room temperature is corresponding；Heating wire component is set in sealed silicone cavity and is soaked in liquid Jie In matter；Power input socket a part exposes to outside the hermetic bag body of upper layer, and another part is sealed in the close of upper layer sealing bag body It seals in cavity, power input socket is electrically connected with electric heater.The liquid medium can be pure water, as an improvement, can also be with For fluid or solution with good thermal storage performance, while liquid medium should be the harmless safe liquid of non-toxic, non-corrosive Body.It should be noted that between different liquid mediums, there is some difference on thermal storage performance, but no matter selects which kind of liquid Medium belongs to the protection scope of the utility model without departing from the concept of the premise utility.

Electric heater includes carrier member 2, heating wire 3, and heating wire is wrapped in carrier member, and the middle part setting of carrier member is multiple Through-hole 20 with the flowing of liquid in convenient bag body and is conducive to the conduction of heat.Hanging hole 23, heating wire is arranged in one end of carrier member Carrier member tail portion has a hollow out position to form hanging hole, and a connecting band 6 passes through the hanging hole and is connected in bag body.Connecting band is fixed on In the silica gel of the two panels up and down seam of the hot-water bottle shell.Connecting band is soft modeling band, and it is soft anti-that the bind end of connecting band is clipped in two panels It is fused among water layer and with the soft waterproof layer hot pressing of two panels, it is therefore an objective to the conducting wire of the tail end of heating wire component be taken up, electric heating is made Device cannot move on a large scale, guarantee that liquid medium is heated evenly.

Carrier member two sides have been placed equidistant with separation cavity, and heating wire makes carrier member by successively winding each separation cavity Front, the back side are formed with horizontally-parallel heating wire arrangement 21.Horizontally-parallel heating wire arrangement of the heating wire at the carrier member back side is outer Side is also wrapped with two or more longitudinal fever strands 22, the power input socket 5 of the close bag body in the front of carrier member.

Heating wire parallel equidistant is arranged in carrier member surface, and there are heat gap structures between heating wire, separates cavity Setting, on the one hand facilitate the winding of heating wire, on the other hand can guarantee that the interval of heating wire is uniform, ensure heating wire component The uniformity of heat dissipation effect and the heat distribution of structure.

When electric heater works, carrier member it is face-up, since longitudinal fever strand and horizontally-parallel heating wire arrange It is vertically arranged, the heating wire that it is arranged by parallel equidistant jacks up, the horizontally-parallel heating wire arrangement of big calorific value and position Soft waterproof layer in bottom is isolated, and avoids electric heater and the soft waterproof layer in bottom close to so that electricity be effectively prevent to add The phenomenon that hot device directly heats bag body shell, product use is more safe and reliable.

While there has been shown and described that the embodiments of the present invention, those skilled in the art should understand that: These embodiments can be carried out with a variety of variations, modification, replacement in the case where not departing from the principles of the present invention and objective And modification, the scope of the utility model are limited by claim and its equivalent replacement, without changing made by creative work Into etc., it should be included within the scope of protection of this utility model.
