Description

Energy-saving electric soldering irons controlled by switch

The utility model relates to a kind of switch control energy-saving electric iron.

It is a kind of soldering appliance that electricity irons.At present, electric iron is pressed whether adjustable branch two classes of power, and a class is furnished with the control device of adjusting the temperature electronically, and another kind of is single power-type.The former structure complexity, the cost height, inconvenience is carried.The latter is with plug double as power switch, and is promptly dangerous, also inconvenient, and in addition, when its energising standby period was longer, electric iron was in " the empty burning " state of rated power, and promptly electricity wasting has shortened service life again.

The utility model is the shortcoming that overcomes and avoid prior art, and a kind of switch control energy-saving electric iron is provided, and this electric iron adopts diode, connects devices such as lead and toggle switch and connects and composes.

The purpose of this utility model provides a kind of switch control energy-saving electric iron, make the electric iron operator need not pull up break-make power supply under the attaching plug situation, make handling safety, convenience, can select different electric thermal powers and duty again, reach saves energy, prevent electric iron " empty burn ", prolong electric iron service life, satisfy of the different requirements of different welding objects welding temperature.Have circuit and constitute simply, easy to operate, low cost and other advantages.

The utility model is achieved in that switch control energy-saving electric iron, and it has attaching plug 1, handle 2, on-off circuit 3, heating 4, tip 5 and shell 6 connect and compose, it is characterized in that on-off circuit 3 is connected lead and toggle switch and connected and composed by diode.

Heating 4 of the present utility model is to be made of single group or two groups of electrothermal devices.

On-off circuit 3 of the present utility model is to be made of single group or two groups of on-off circuits.

On-off circuit 3 of the present utility model can be contained on the handle 2.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the circuit theory diagrams of the utility model list heating.

Fig. 2 is the circuit theory diagrams of the two heatings of the utility model.

Fig. 3 is a structural representation of the present utility model, and as Figure of abstract.

As shown in Figure 1, the O end is two outputs of heating 4 with the P1 end, represents this heating with W, and the O end directly is connected in an end of attaching plug 1, and on-off circuit 3 is by toggle switch K, and diode Z1 and connection lead L1 constitute.Toggle switch K divide A, B, and the C third gear, K places the C shelves, and the P1 end of heating 4 is connected power supply through connecting lead L1, and the electric iron power output is heating 4 rated output powers, corresponding electric iron normal operating conditions.When K places the B shelves, diode Z1 is connected in series the P1 section into heating 4, compare with the C shelves, because the back-pressure cut-off characteristics of diode Z1, half has fallen in the voltage effective value that heating 4 is born, because of square being directly proportional of its power output and voltage, then its power output is reduced to 1/4th of C shelves normal operating conditions, corresponding electric iron give hot state.When electric iron energising standby period was longer, giving hot state can economize on electricity, and prevented the empty burning of electric iron, increased the service life, and simultaneously, can make the tip of electric iron keep certain temperature again, did not influence to re-use.K places the A shelves, cuts off working power.

As shown in Figure 2, heating 4 of the present utility model can also be two group electrothermal device W1 formations of connecting with W2.The O end is the end of electrothermal device W2, and the P2 end is the tie point of W1 and W2, and the P1 end is the end of W1.On-off circuit 3 is on circuit diagram shown in Figure 1 basis, has increased diode Z2, connects lead L2, and also corresponding D shelves and the E shelves of having increased of toggle switch K form two group on-off circuits.Wherein the end of diode Z2 is connected with the P2 end, and the other end is connected with the D shelves of toggle switch K, connects lead L2 two ends and is connected with the E shelves of P2 end and K respectively.When K places the C shelves, electrothermal device W1 connect with W2 electric work, the electric iron power output is W1 and W2 power output sum, K puts the E shelves, electrothermal device W2 gets electric work, the electric iron power output equates with the W2 power output.K puts the B shelves, and the electric iron power output is reduced to 1/4th of C shelves, and K puts the D shelves, and the electric iron power output is reduced to E shelves 1/4th.K puts the A shelves, and electric iron must not.

As shown in Figure 3, on-off circuit 3 can be contained on the handle 2, and heating 4 is loaded in the shell 6, shell 6 is fixed on the handle 2, and when electric iron is the internal heat type working method, tip 5 is placed on the shell 6, when electric iron is the external-heat working method, tip 5 inserts in the heatings 4.
