Description

Curve saw blows dust absorbing structure

Technical field

The utility model relates to a kind of curve saw, particularly relates to a kind of curve saw and blows dust absorbing structure.

Background technology

Curve is sawed, and the curve saw of especially hand-held formula, all has base plate, the fuselage being arranged on base plate, the motor being arranged in fuselage, driven by motor transmission rig cuts workpiece to drive saw blade to move back and forth, when carrying out work piece cut, base plate is placed on workpiece. Operator promotes curve saw to make base plate relative to workpiece motion s, thus makes saw blade carry out the cutting of straight line or curve. If an application number is the Chinese invention patent " curve saw " of ZL201010105111.0 (publication number is CN102126232A), and application number is the Chinese invention patent " curve saw " of ZL200410044852.7 (notification number is CN1704194A), they all disclose a kind of like this curve saw.

Existing curve is sawed in cutting process, capital produces a large amount of wood chip at saw blade and the cutting position being cut timber, wood chip can stop the line of cut that we are drawn on timber in advance, cause not cutting according to pre-fixed line, affect cutting accuracy, in addition such as the sawdust of overheap, frictional force when circular saw blade is cut can be increased, cause saw blade to generate heat, affect the working efficiency of electronic annular saw, and circular saw blade is easily damaged. After cutting work completes, having a large amount of sawdust and pile up, also need after having cut, the sawdust meeting splashes that cutting produces, affects operating environment.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of can not only being blown off by the wood chip of generation the curve saw that the sawdust of generation siphons away can also be blown dust absorbing structure.

The utility model solves the problems of the technologies described above the technical scheme adopted: a kind of curve saw blows dust absorbing structure, comprise fuselage, the motor being arranged in fuselage, it is characterized in that: be provided with in described fuselage and blow dirt passage and dust absorption passage, blow the cutting position of outlet facing to forebody of dirt passage, blow and it is connected by valve port between dirt passage and dust absorption passage, valve port position is provided with the valve that can be connected blowing dirt passage with dust absorption passage or close, the going out air port and blow dirt channel connection of the heat radiation fan of described motor, the end of described dust absorption passage is provided with the dust suction pipe in order to be connected with suction cleaner.

As improvement, above-mentioned valve is rotatably connected on the side of valve port, the control that fuselage is provided with control valve opening and closing pushes away torsion, control be located on fuselage with pushing away torsion energy Relative sliding and can be positioned in front portion or rear portion, it is provided with in fuselage and pushes away, with controlling, the pushing block turned round and be connected, pushing block is positioned at dust absorption passage and coordinates with valve sidewall, control push away turn round move forward and be positioned at front portion state under, valve is also remained on close port position by pushing block band movable valve, move after control pushes away torsion and under being positioned at rear portion state, pushing block is away from valve and remains on separate location place. The keying of valve is turned round by manually promoting control to push away and is realized control, has that structure is simple, operation labour-saving advantage, certainly also can adopt the control gate structure of torsion spring structure.

Above-mentioned fuselage has bar hole, an inwall place of bar hole is respectively provided with two locating slots arranged along time interval, described control pushes away torsion and has two extensions downwards and upper and lower spaced elasticity insertion section, in described elasticity insertion section insertion bar hole, one of them elasticity insertion section has the protruding positioning bar matched with described locating slot. Being joined by the card of elasticity insertion section and bar hole, prevent control from pushing away and turn round disengaging fuselage, be also convenient to control simultaneously and push away on torsion loading fuselage, joined the location realizing controlling to push away the valve opening and closing position of torsion by the card of positioning bar and locating slot, structure is simple.

In above-mentioned valve towards the end face blowing dirt passage be the cambered surface arched upward. Suction cleaner is convenient in the setting of cambered surface, and that valve air-breathing is opened rear windage is less, is more conducive to dust suction.

Compared with prior art, the utility model has the advantage of: this structure makes curve saw have two kinds of operating mode, the first blows dirt pattern, when valve closes valve port, only blow its effect of dirt passage, the wind of motor heat dissipation fan blowout exports to the cutting position of saw blade via blowing dirt passage, after cutting starts, the wind of motor radiating fan blowout can continue to blow the sawdust gathered off, guarantee that cutting is more accurate, the working efficiency of saw blade is higher simultaneously, and not easily damage, the wind that this structure utilizes motor heat dissipation fan to blow out carries out blowing dirt, without the need to additionally arranging fan structure, more energy-conserving and environment-protective, 2nd kind is cleaned model, when valve open, dust suction pipe is connected with suction cleaner, the suction of suction cleaner is answered to be greater than the wind-force of motor heat dissipation fan blowout, therefore, the sawdust produced during work can be sucked via dust absorption passage in the dust bag of suction cleaner, can not produce to fly bits, reach the Working environment without dirt, it is beneficial to the healthy of operator.
