Description

Automatic squash type electric iron

Technical field

The utility model relates to a kind of electric iron, is specially a kind of automatic squash type electric iron.

Background technology

At present, electric iron is widely used soldering appliance, and it utilizes electric heater heating soldering tip, and soldering tip fusing scolding tin comes work, and is simple and practical.But, existing electric iron is because soldering tip and scolding tin separates, during welding, the soldering tip of heating dips in from the scolding tin box gets scolding tin, weld less important dipping in and get scolding tin one time, in dipping in the process of getting scolding tin, the scolding tin of fusing is easy on work top, the work top of making dirty, be not easy very much after the scolding tin condensation to remove, can not recycle, cause waste.

Summary of the invention

The utility model provides a kind of automatic squash type electric iron in order to solve existing electric soldering iron tip and the scolding tin branch problem that institute's scolding tin that causes wastes that is arranged.

The utility model is to adopt following technical proposal to realize: automatic squash type electric iron, comprise the soldering tip that is connected with handle, cavity is arranged in soldering tip inside, cavity top is provided with scolding tin and adds inlet, cavity inner wall is fixed with the zone of heating that extends to cavity front end stannum export and be connected with power line, soldering tip and handle junction are provided with trigger, fix between trigger and the handle back-moving spring is arranged, trigger stretches in the cavity, be fixed with the elastic rack of offering unidirectional teeth on trigger top, elastic rack and advance and be engaged with forward gear between the tooth bar; In the groove on the axle one end insertion cavity wall of forward gear, the other end passes cavity wall, the tooth bar side of advancing in cavity top is provided with and retreats tooth bar, retreat the backward gear that the tooth bar engagement has pinion, backward gear is fixed on the cavity wall by axle, advance tooth bar with retreat the piston that tooth bar is fixedly connected on cavity cooperates on.Because soldering tip has been arranged to cavity, the piston that is provided with by gear and tooth bar transmission cooperates with cavity, during use, add inlet from scolding tin and add scolding tin, connect power supply, zone of heating is with the scolding tin heat fused, cocking backward, elastic rack moves backward, and the forward gear rotation drives the tooth bar that advances and moves, and the tooth bar that advances promotes piston and moves.Because the effect of the spring that is connected with trigger, unclamp trigger after, trigger automatically resets.Because the teeth of elastic rack are unidirectional offering, piston did not move when trigger resetted.In the groove on the axle one end insertion housing of forward gear, axle can slide in groove, and the other end of axle passes housing, and the part of passing housing constitutes switching push button.Press down switching push button, forward gear break away to connect the tooth bar that advances of piston, the sidepiece pinion engagement of forward gear and backward gear, and cocking backward, elastic rack moves, and through the drive of forward gear and backward gear, piston is mobile backward.

Above-mentioned automatic squash type electric iron, its soldering tip is coated with heat-insulation layer.Owing to be provided with heat-insulation layer, make that the heat loss of soldering tip is little.

The utility model is owing to be arranged on scolding tin in the cavity of soldering tip, makes the electric iron scolding tin that in use can not drop, and saved scolding tin, and easy to use, effect is remarkable.

The specific embodiment

With reference to the accompanying drawings present embodiment is further described, present embodiment is to explanation of the present utility model, is not that the utility model is done any restriction.

Automatic squash type electric iron, comprise the soldering tip 1 that is connected with handle 7, soldering tip 1 is coated with heat-insulation layer, cavity 13 is arranged in soldering tip 1 inside, cavity 13 tops are provided with scolding tin and add inlet 3, cavity 13 inwalls are fixed with the zone of heating 2 that extends to cavity 13 front end stannum exports 12 and be connected with power line, soldering tip 1 is provided with trigger 8 with handle 7 junctions, fix between trigger 8 and the handle 7 back-moving spring is arranged, trigger 8 stretches in the cavity 13, is fixed with the elastic rack 9 of offering unidirectional teeth on trigger 8 tops, elastic rack 9 and advance and be engaged with forward gear 10 between the tooth bar 6, in the groove 14 on axle 15 1 ends insertion cavity 13 walls of forward gear 10, the other end passes cavity wall; Tooth bar 6 sides of advancing in the cavity 13 top is provided with and retreats tooth bar 5, retreat the backward gear 11 that tooth bar 5 engagements have pinion 17, backward gear 11 is fixed on the cavity wall by axle 16, advance tooth bar 6 with retreat tooth bar 5 and be fixedly connected on the piston 4 that cooperates with cavity 13.

During use, add inlet 3 from scolding tin and add scolding tin, connect power supply, zone of heating 2 is with the scolding tin heat fused.Owing to be provided with heat-insulation layer, make that the heat loss of soldering tip is little.Cocking 8 backward, and elastic rack 9 moves backward, and forward gear 10 rotations drive the tooth bar 6 that advances and move, and the tooth bar 6 that advances promotes pistons 4, extrudes scolding tin from outlet.Unclamp trigger 8, because the effect of the back-moving spring that is connected with trigger 8, trigger 8 resets.Because the teeth of elastic rack 9 are unidirectional offering, piston 4 did not move when trigger 8 resetted.In the groove 14 on axle 15 1 ends insertion cavity 13 inwalls of forward gear 10, axle 15 can slide in groove 14, and the other end of axle 15 passes cavity 13 inwalls, and axle 15 parts that pass cavity 13 inwalls are switching push buttons.Press down switching push button, forward gear 10 breaks away to be fixed in and retreats tooth bar 6 on the piston 4, forward gear 10 meshes with the sidepiece pinion 17 of backward gear 11, cocking 8 backward, elastic rack 9 moves, have the drive of the backward gear 11 of pinion 17 through forward gear 10 and sidepiece, piston 4 moves backward, add scolding tin again or behind piston, move in will be sucked in the cavity 13 by the scolding tin that soldering tip melts.
