Abstract

The utility model relates to a mains plug in use for a feet warm plate, which comprises a plug body, plug pins, a supply lead or an output, a switch, and an LED for indication. The plug body is provided with a power regulating switch which is short connected with a diode on the power supply circuit in series. The utility model has the advantages of simple structure, reasonable structure, power regulating function, compact structure, small size and low cost. The utility model is particularly suitable for power supply matching products like feet warm plates.

Description

The attaching plug that is used for feet warm plate

The utility model relates to a kind of attaching plug that is used for feet warm plate, particularly a kind of attaching plug that is applicable to the variable power of feet warm plate.

Plug of the prior art is varied, but for many electric heating products, especially for the feet warm plate of warm foot, the circuit working state indication should be arranged, and the more important thing is to have the power adjustments gear, and answers compact conformation, and cost is low.

The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of power supply that can control feet warm plate is provided, and can be used for the conversion of input power of feet warm plate and simple in structure, easily manufactured again, the attaching plug that cost is low.

The attaching plug that is used for feet warm plate of the present utility model comprises header body, pin, power supply lead wire or output, switch, the light-emitting diode of indication, it is characterized in that: power regulating switch is housed on the header body, and the power regulating switch short circuit is connected on the diode on the current supply circuit.

The attaching plug that is used for feet warm plate of the present utility model, simple and reasonable for structure, have the high or low power regulatory function, the power supply of products such as feet warm plate that is particularly suitable for similar electric heating is supporting, and compact conformation, and volume is little, and cost is low, has vast potential for future development.

For introducing the attaching plug that is used for feet warm plate of the present utility model in detail, be elaborated below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of facing of the attaching plug that is used for feet warm plate of the present utility model;

Fig. 2 is the sectional structure schematic diagram of Fig. 1;

Fig. 3 is the electrical block diagram of a kind of embodiment;

Fig. 4 is the electrical block diagram of another kind of embodiment.

Referring to Fig. 1 to Fig. 4, the utility model is a kind of attaching plug that is used for feet warm plate, it comprises header body 10, pin 3, power supply lead wire or output 7, switch 2, the light-emitting diode 1 of indication, it is characterized in that: power regulating switch 6 is housed on the header body, and power regulating switch 6 short circuits are connected on the diode 5 on the current supply circuit.

Light-emitting diode 1 plays indication, and a kind of scheme is to be attempted by power supply lead wire or output 7 (Fig. 4) by step-down current-limiting resistance 4, and another kind of scheme is by pressure limiting resistance 4 ' be serially connected in (Fig. 3) on the power line.

The effect of power switch 6 is to manage to be connected in series a rectifier diode 5 when needs are turned down power in current supply circuit, its technical scheme is to make rectifier diode 5 in parallel with power switch 6 shown in Fig. 3 and 4, when power switch 6 open circuits, rectifier diode 5 is had an effect, reduce the power of half, otherwise 6 on the switch that closes plays the short circuit effect to diode 5.

From Fig. 1 and 2 as seen, switch 2 is positioned on the header body 10 side by side with power switch 6, has both brought the compactness of structure, also has the convenient characteristics of using.

Load Rt in the circuit diagram among Fig. 3 and 4 is feet warm plate.
