Description
Technical Field
The utility model relates to an electron, electrical apparatus power supply heating field especially relate to an external power control and temperature regulation switch.
Background
Household appliances are generally powered by connecting to a household outlet via a power cord. Such as a refrigerator, an air conditioner, a television and the like of household appliances are connected to a 220V power socket through a power line with a plug so as to power on the appliances. For heating devices such as electric heaters, electromagnetic ovens and the like, electric energy is obtained through power lines. In practical application, when an electric appliance needs to be used, a plug is inserted into a socket to achieve electrification. When the electric appliance is not used, the plug is pulled out of the socket, and the power supply is cut off. However, the plug is not convenient to be plugged in when power is on or pulled out when power is off. Therefore, chinese patent publication No. CN201570742U discloses a power cord of an electric rice cooker, in which a power control switch is disposed in the middle of the power cord, so as to avoid the disadvantage that a user must insert or remove two plugs on the power cord into or from a 220V power socket and the electric rice cooker respectively when powering on or off the electric rice cooker. For another example, chinese patent publication No. CN202084750U discloses a power cord with a switch, which is formed by adding an auxiliary switch on the basis of a common power cord, and installing the auxiliary switch at the position of a plug of the power cord, so that the on/off of the current of the power cord can be conveniently controlled by the on/off of the auxiliary switch. When the power line plug is inserted into the socket, the power line is not electrified as long as the auxiliary switch is not turned on, and the power line can be electrified only after the auxiliary switch is turned on. Therefore, when people need to turn off certain current, the plug does not need to be pulled out of the socket, and only the auxiliary switch on the plug needs to be turned off, so that the use is very convenient.
The power cord disclosed above is indeed convenient for general furniture appliances. However, there is a need for temperature control for devices with special requirements such as heated and insulated dining tables, holding ovens, slow cookers, liquid curing prevention devices, animal drinkers, and the like.
At present, heating heat preservation products generally set up on-off switch and temperature regulation switch inside the dining table body. However, since the on-off switch and the temperature adjustment switch have a certain volume, this method requires a corresponding space inside the product body to install the switch. In addition, because the temperature inside the heating and heat-preserving dining table is higher, after the switch is arranged inside the dining table, the service life of the switch in a high-temperature environment can be greatly influenced after long-time use, and even the service performance of the switch is influenced. If an external switch can be designed, and the temperature regulation control and the on-off control are designed into a whole, the problems can be well solved.
