Abstract
The utility model discloses an electric hot-water bag provided with an external electric heating element, comprising a bag body and a power cord. The utility model is characterized in that heat conductive liquid is stored inside the intracavity of the bag body; a storage groove is arranged on the bag body wall and is provided with a heat conductive wall made of heat conductive material; and an electric heating element is arranged inside the storage groove and is electrically connected with the power cord. In service, the electric heating element conducts the heat to the heat conductive liquid inside the intracavity of the bag body through the heat conductive wall made of the heat conductive material. The electric hot-water bag has the advantages of simple and reasonable structure, convenient installation of the electric heating element and easy check and replacement.
Description
Technical field
This utility model relates to a kind of electric warm water bag, especially a kind of electric warm water bag of external electric heating body.
Background technology
Existing electric warm water bag, its structure comprises bag and power line, stores heat-conducting liquid and electric heating body in the bag, and electric heating body is immersed in the heat-conducting liquid, and electric heating body is electrically connected with power line.The electric warm water bag of this structure directly heats the intravital heat-conducting liquid of bag by electric heating body.1), because electric heating body is installed in the bag it has the following disadvantages:, therefore, certain difficulty is arranged when electric heating body is installed; 2), when electric heating body damages, be difficult for detecting and changing.
The utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and provides a kind of simple and reasonable for structure, and electric heating body is easy for installation, and is convenient to the electric warm water bag of the external electric heating body that detects and change.
The purpose of this utility model is achieved in that
A kind of electric warm water bag of external electric heating body, comprise bag and power line, the bag inner chamber stores heat-conducting liquid, described bag wall portion is provided with ccontaining cavity, ccontaining cavity has the heat conducting wall of being made by Heat Conduction Material, be provided with electric heating body in the ccontaining cavity, electric heating body is electrically connected with described power line.During work, electric heating body is by the heat conducting wall made by the Heat Conduction Material heat-conducting liquid with heat transferred bag inner chamber.
The purpose of this utility model can also adopt following technical measures to solve:
As further specifically improving structure, can be according to instructions for use, described heat conducting wall is non-disconnectable structure and is fixed on bag wall portion; Or heat conducting wall is removable structure and is fixed on bag wall portion.
For improving the heat transfer effect of electric heating body, described ccontaining cavity is arranged on the heat conducting wall, and electric heating body is close to heat conducting wall.
Described ccontaining cavity top is equiped with the electrical socket that can be electrically connected with power line, and electrical socket is electrically connected with electric heating body.
Also be provided with temperature controller on the described ccontaining cavity, temperature controller is electrically connected with electrical socket; Temperature controller is not arranged on the bag inner chamber, and is arranged on the ccontaining cavity, and its water-stop degree is less demanding, and convenient the installation and replacing.
The beneficial effects of the utility model are:
1), electric warm water bag of the present utility model is by being provided with ccontaining cavity in bag wall portion, ccontaining cavity has the heat conducting wall of being made by Heat Conduction Material, electric heating body is arranged in the ccontaining cavity, during the electric heating body heating, heat is passed in the heat-conducting liquid of bag inner chamber by heat conducting wall; Because electric heating body is external and is arranged on outside the bag inner chamber, therefore, electric heating body is not subjected to the structural limitations of bag inner chamber, has not only made things convenient for the installation of electric heating body, and is convenient to detection and replacing to electric heating body;
2), the electric warm water bag of this structure, simply electric heating body is arranged on bag wall portion, and, can realizes that it is simple and reasonable for structure to the effect of the heat-conducting liquid heating of bag inner chamber by the heat conducting wall of being made by Heat Conduction Material being set in bag wall portion; Moreover because electric heating body is arranged in the ccontaining cavity of bag wall, promptly the sidewall of electric heating body and diapire transmit heat all as heating face to heat conducting wall, to increase area of heat transfer, improve the heats to heat-conducting liquid effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A place enlarged drawing of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, a kind of electric warm water bag of external electric heating body, comprise bag 1 and power line 2, bag inner chamber 101 stores heat-conducting liquid 3, described bag wall portion 102 is provided with ccontaining cavity 103, ccontaining cavity 103 has the heat conducting wall of being made by Heat Conduction Material 4, is provided with electric heating body 5 in the ccontaining cavity 103, and electric heating body 5 is electrically connected with described power line 2.Described heat conducting wall can be arranged to be non-disconnectable structure with heat conducting wall 4 and be fixed on bag wall portion 102 according to instructions for use, or is removable structure and is fixed on bag wall portion 402.
For improving the heat transfer effect of electric heating body 5, described ccontaining cavity 103 is arranged on the heat conducting wall 4, and electric heating body 5 is close to heat conducting wall 4.
Described ccontaining cavity 103 tops are equiped with the electrical socket 6 that can be electrically connected with power line 2, and electrical socket 6 is electrically connected with electric heating body 5.Also be provided with temperature controller 7 on the described ccontaining cavity 103, temperature controller 7 is electrically connected with electrical socket 6.
Operation principle: during electric heating body 5 heating, heat is passed in the heat-conducting liquid 3 of bag inner chamber 101 by heat conducting wall 4; Because electric heating body 5 is external and is arranged on outside the bag inner chamber 101, therefore, electric heating body 5 is not subjected to the structural limitations of bag inner chamber 101, has not only made things convenient for the installation of electric heating body 5, and is convenient to detection and replacing to electric heating body 5;
