Breathable and heat-conductive electric blanket

This creation is about a ventilated and heat-conductive electric blanket, especially a ventilated and heat-conductive electric blanket with a soaking structure.

Referring to FIG. 9 together, the electric blanket comprises a carpet body 60, which is made of polyester fiber and includes a spacer body and a lower sheet body, and an outer sheet and a lower sheet body. Connected to each other, an accommodating space is formed between the upper body and the lower body, and a power socket 61 is disposed on the carpet body 60. The power socket 61 can be connected to the mains, and the electric heating wire 62 is disposed in the carpet body 60. The hot wire 62 is connected to the power supply base 61. The electric heating wire 62 is bent and evenly distributed in the carpet body 60. The electric heating wire 62 can be heated by the power supply supplied from the power supply base 61, so as not to cause adjacent electric power. The hot wires 62 are in contact with each other to form a short circuit. On the upper and lower portions of the carpet body 60 at the interval between the adjacent heating wires 62, the upper and lower plates are connected by ultrasonic welding or adhesive bonding. The body is further formed with a plurality of connecting portions 63 which are spaced apart from each other, and the connecting portions 63 are blocked between the adjacent heating wires 62 to prevent mutual contact with each other to form a short circuit, and the position of the heating wire 62 can be maintained. The heating temperature is evenly distributed.

However, whether the upper or lower body is superposed by ultrasonic fusion bonding to form the connecting portion 63, or the connecting portion 63 is formed by adhesive, the connecting portion 63 has better heat conduction than the surrounding carpet body 60. Effect, the actual use of electricity In the case of the thermal blanket, the connecting portion 63 absorbs the heat generated by the heating wire 62 more easily than the surrounding portion, so that each connecting portion 63 forms a hot spot having a higher temperature than the surrounding temperature. After a long period of use, the temperature of the hot spot is more likely to occur. It rises to a higher temperature that makes the user feel uncomfortable and therefore still has to be improved.

In view of the disadvantage that the connection portion provided on the ventilated and heat-conductive electric blanket of the prior art may overheat after a period of use, the present invention has a ventilated and heat-conductive electric blanket which can achieve the object of reducing the temperature of the joint portion.

In order to achieve the above object, the technical means used in the present invention include: providing a carpet body, a heating wire, a power socket and a plurality of connecting portions; the carpet body comprises an upper body and a lower body; the heating wire Between the upper body and the lower body, the heating wire is bent in a plurality of stages to form a plurality of heating sections arranged at intervals; the power socket is disposed on the carpet body and electrically connected to the heating wire; Portions of the body and the lower body are connected to each other to form the connecting portions, and the connecting portions are respectively distributed at intervals between the heating segments, and each connecting portion and its surrounding area form a connecting portion, which is disposed on each connecting portion. There is at least one venting hole.

The ventilating and heat conducting electric blanket, wherein the venting hole is disposed on the connecting portion.

The ventilating and heat-conductive electric blanket, wherein the venting hole is a circular hole.

The gas permeable and heat conductive electric blanket, wherein the vent hole is located in the At the outside of the connection.
