At present, electric warm water bag is easy to use with it, and temperature retention time is long, and is subjected to consumers in general's use deeply, because electric warm water bag energising could heat, thereby people are more and more higher to its security requirement, particularly to the fail safe of its electro-heat equipment.And the electro-heat equipment of existing hot-water bag, as shown in Figure 1, comprise heating bar 1a, thermostat 2a, have housing 3a, lead 4a and the supply socket 5a of cavity volume, heating bar 1a and thermostat 2a are located at respectively in the cavity volume of housing 3a, supply socket 5a is provided with the through hole 51a that wears for lead 4a, between heating bar 1a, thermostat 2a and the supply socket 5a lead 4a is set and is electrically connected.Its supply socket 5a is made up of the seal receptacle 52a with cavity, the silica gel 6a and the pedestal 53a of sleeve on seal receptacle 52a cavity volume that are filled in the seal receptacle cavity, and pedestal 53a is provided with contact 54a.And heating bar 1a and thermostat 2a are installed on that housing 3a goes up and be electrically connected with supply socket 5a by lead 4a, are filled with silica gel 6a in the cavity volume of housing 3a and enter to prevent liquid with the soldering opening of sealed guide 4a, heating bar 1a and temperature detector 2a.1), this electro-heat equipment is to want to be connected the pin on the pedestal with an end of lead earlier in the course of processing but there is following shortcoming in the electro-heat equipment of this class hot-water bag:, filling gel and make pin on the pedestal immerse anti-liquid to enter in the seal receptacle cavity then, simultaneously thermostat and heating bar are installed on the housing cavity volume, and be connected with the other end of lead, then in the cavity volume of housing filling gel with the soldering opening of sealed guide and heating bar and thermostat, as seen its installation and processing complexity, production efficiency is low.2) because lead directly is immersed in the liquid of bag body, and it utilizes silica gel to seal the soldering opening of each electric elements as encapsulant, thereby its sealing is relatively poor, liquid in the bag body easily enters in the electric elements, thereby cause short circuit, its fail safe is relatively poor, critical user's safety.

The utility model content

The purpose of this utility model is to solve above-mentioned shortcoming, and good airproof performance is provided, and is safe in utilization, the simple electric warm water bag electric heating device of installation and processing.

The purpose of this utility model is achieved in that the electric heating device that is used on the electric warm water bag, comprise heating bar, thermostat, housing with cavity volume, lead and supply socket, heating bar and thermostat are located at respectively in the cavity volume of housing, supply socket is provided with the through hole that wears for lead, heating bar, between thermostat and the supply socket lead being set is electrically connected, being provided with adaptive catheter block between described supply socket and the housing is connected, the opening of catheter block two ends difference closed shell cavity volume and the through hole in the supply socket, also have cavity on the catheter block, cavity connects the through hole in housing cavity volume and the supply socket, supply socket and heating bar, lead between the thermostat is placed in the cavity of catheter block.

Described catheter block is "T"-shaped, and the catheter block top of T shape is fixed on the opening of housing cavity volume, and the bottom extends to the through hole of supply socket, and is whole with supply socket and is connected.

Described socket comprises the base of being with cavity volume and is fixed in attaching plug in the base cavity volume that have through hole on the described base, the bottom of T shape catheter block is fixed on the through hole.

The periphery of described base cavity volume opening is provided with bleeder port, is fixed with sealing plug on the described exhaust outlet.

Described plug comprises interface that is connected with contact and the lamp socket that indicator light is installed.

The end of described plug is connected with a transparent panel, has the through hole that is communicated with interface on the panel, is stamped cover plate on the described through hole.

1), owing to be provided with adaptive catheter block between described supply socket and the housing and be connected the beneficial effects of the utility model are:, thereby when installing, the plug welding of wire bonds with supply socket, make lead pass the cavity of catheter block then and plug is fixed on the pedestal, again heating bar and the thermostat of lead on being installed on housing is electrically connected, at last the termination of the opening of housing cavity volume and catheter block is tightly connected, so just finish the installation of electro-heat equipment, as seen its installation and processing is simple, has improved production efficiency widely; 2) and catheter block and supply socket are whole and are connected, and the cavity volume of the end of conduit and housing is tightly connected, and liquid is difficult to enter in the cavity volume of housing, its good airproof performance, and fail safe is good.
