Description

Direct temperature type electric frying pan separable power plug connector, plug connector connection structure

The invention relates to the technical field of electric frying pans and pancake machines, in particular to a direct-sensing electric frying pan separable power plug connector and a plug connector connection structure. Background technique

With the continuous improvement of living standards, electric cookers for frying, roasting, baking and other foods have begun to be used by a wide range of households; especially electric frying pans or pancake machines, whose structure includes electric frying pans or electric frying The disk body, the electric frying pan body or the electric frying pan body itself extends out of the power cord, and the outer end of the power cord is arranged to connect the plug of the external power source, and the other end of the power cord is connected with the electric heating component in the pot body in a fixed manner; The external plug of the power cord can be connected to an external power source; however, the electric frying pan of the above structure still has the following disadvantages: (1) due to the use of the power cord and the electric frying pan or the electric frying pan (electric heating element) Fixed connection, not separable, if the power cord is damaged, it is not easy to replace, even if the power cord is damaged, the pot can not be used; (2) It is not possible between the power cord and the electric frying pan or the electric frying pan The effect of the splitting, when the electric frying pan body or the electric frying pan body is not in use, the power cord is always stored together with the pot body, which brings certain inconvenience to the daily use; (3) Frying pan, the disk can not be cleaned because they can not be separated from the power source line on the dishwasher.

In the other electric cookers on the market, there is also a common plug and socket connection between the pot body and the power cord. This connection makes the power cord and the pot and the disc body separable; however, There are some defects as follows: (1) There is a gap between the heat transfer mechanism on the plug and the socket, that is, there is no direct metal contact, but indirect heat transfer through the air, and the heat transfer effect is poor, resulting in a sense of the thermostat. The temperature value is inaccurate and the temperature control accuracy is poor. (2) The power cable and the pot body are connected by a simple plug and socket. The connection is not fast enough, and it is easy to loose and affect the use; (3) Simple plug and socket connection, the safety factor is low, and the child can easily dial the power cord directly; (4) When the plug is not inserted into the tip (that is, it is not fully inserted into the socket), it can still be energized, and the thermostat does not work, which is easy to cause dry burning, and there is a hidden danger in safety, which may be caused by loose or hot plug.
