Abstract
The utility model discloses a micro-electric solder sucker which comprises a suction tube, a filter and a solder sucking head at the front end of the filter. A vacuum pump connected with a motor is arranged in the suction tube; the valve core of an electromagnetic valve is inserted in a hole in the center of a seal ring; the diameter at the rear end of the valve core is smaller than the pore diameter of the round hole in the center of the seal ring; and a power supply device is further arranged in the suction tube. When the solder sucker is in use, the air in the upper part of the seal ring is discharged through the vacuum pump to form negative pressure; the valve core is instantly propped out through a solder sucking switch and the air in the solder sucking head is led to the negative pressure cavity; and the melt solder is sucked into the filter under the effect of atmosphere outside the solder sucking head so that the solder suction process is finished. The utility model has the advantages of simple structure, low manufacture cost, portability, and small shaking during use, and can effectively prevent circuit board damage.
Description
Technical field

The utility model content
At the problems referred to above, the utility model provides a kind of miniature electric solder sucker, and it is little that it has a volume, use simple, safe and efficient advantage.
For reaching above purpose, the technical scheme that the utility model is taked is:
A kind of miniature electric solder sucker, the tin sucting head that comprises suction tube, filter and filter front end, described suction tube inside is provided with the vavuum pump that is connected with motor, and valve core of the electromagnetic valve is plugged in the hole of sealing ring central authorities, and described spool rear end diameter is less than sealing ring central circular hole aperture; Also be provided with supply unit in the described suction tube.
The technical scheme that realizes the utility model purpose also further comprises:
Described supply unit is the supply hub of socket power.
Suction tube is provided with power switch and inhales the tin switch, inhales the tin switch and is electrically connected with magnetic valve.
Be provided with filter between sealing ring and the tin sucting head, described filter comprises scruff screen pack and the airstrainer that sets gradually from outside to inside.
Be provided with the gap between described sealed picture and the filter, form common pressure chamber; Be provided with the gap between filter and the tin sucting head, form storage tin chamber.
Described suction tube, tin sucting head and filter are respectively equipped with screw thread, and filter and tin sucting head are connected with stubborn the closing of suction tube.
The utility model is simple in structure, and low cost of manufacture is easy to carry, uses vibrations little, can effectively prevent to damage circuit board.
Description of drawings
Fig. 1 is the utility model structure cutaway view one.
Fig. 2 is the utility model structure cutaway view two.
Among the figure, 1. supply hub, 2. vavuum pump, 3. motor, 4. negative pressure cavity, 5. common pressure chamber, 6. sealing ring, 7. tin sucting head, 8. storage tin chamber, 9. airstrainer, 10. magnetic valve, 11. spools, 12. inhale the tin switch, 13. scruff screen packs, 14. power switches, 15. suction tubes, 16. screw threads.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Be illustrated in figure 1 as the utility model structure cutaway view one.The utility model is provided with supply hub 1 at suction tube 15 tops, external 12V dc source.Suction tube 15 tops also are provided with power switch 14, during use, power supply lead wire are inserted in the supply hub 1, turn on the power switch 14 and get final product.Suction tube 15 tops are provided with vavuum pump 2, and vavuum pump 2 diameters approach suction tube 15 internal diameters, and by fluid sealant it are sealingly fastened on suction tube 15 inwalls.Vavuum pump 2 bottoms and motor 3 are connected to vavuum pump 2 the power input are provided.Suction tube 15 inside are provided with magnetic valve 10, and the work of the suction tin switch 12 control magnetic valves that are electrically connected with it is set on the suction tube wall.In magnetic valve 10 lower cavity sealing ring 6 is set, described sealing ring 6 central authorities are provided with circular hole, and the spool 11 of magnetic valve is plugged in this circular hole.This spool 11 is made by soft silica gel or plastic material, and its point diameter approaches sealing ring 6 central circular hole apertures, can realize sealing; Its rear end diameter is less than sealing ring 6 central circular hole apertures, and forms the gap between sealing ring 6 central circular holes.Between sealing ring 6 and tin sucting head 7 filter is set, described filter comprises scruff screen pack 13 and the airstrainer 9 that sets gradually from outside to inside, is used for preventing that the metal scruff that sucks in from damaging sealing ring 6.Scruff screen pack 13 is for to be made of the bigger metal staple of hardness, and effectively preventing the impact of scruff, airstrainer 9 is made by materials such as sponge, flannelettes, prevents that airborne molecule from entering suction tube 15 tops and damaging magnetic valve or vavuum pump.Be provided with the gap between sealing ring 6 and the airstrainer 9, form common pressure chamber 5.Be provided with the gap between scruff screen pack 13 and the tin sucting head 7, form storage tin chamber 8, be used for storing the scruff that sucks in.Suction tube 15 front ends are provided with external screw thread 17, and the filter inwall is established internal thread, twist to close with suction tube 15 to be connected, and can and change screen pack with scruff in its cleaning storage tin chamber, dismounting back.The filter front end is provided with external screw thread 16, and tin sucting head 7 inwalls are provided with internal thread, twists to close with filter to be connected.
Operation principle of the present utility model is: after supply hub 1 is connected power supply, turn on the power switch 14, motor 3 drives vavuum pump 2 and starts working, and vavuum pump is discharged suction tube 15 inner seal rings 6 with the top air, form negative pressure cavity 4.During use, by inhaling 10 work of tin switch 12 control magnetic valves, valve core of the electromagnetic valve 11 stretches out forward, its front end stretches out sealing ring 6 central circular holes, its rear end is positioned at this circular hole, as shown in Figure 2, because spool 11 rear end diameters are less than sealing ring central circular hole aperture, moment is put into negative pressure cavity 4 with the air in common pressure chamber 5 and the storage tin chamber 8, thereby make 7 air pressure inside moments of tin sucting head less than external pressure, near the liquid tin that is melted by electric iron the tin sucting head 7 externally enters in the storage tin chamber 8 under the atmospheric pressure effect, finishes the tin process of inhaling.Withdrawing by the spring that is provided with in the electromagnet in spool moment ejection back, forms sealing with sealing ring once more, waits for the tin process of next time inhaling.Because it is little that this inhales the vibrations of tin process mechanism, can effectively prevent to inhale the damage of tin vibrations to circuit board, reach the purpose of safe handling.
