Electric suction device

This creation is about a soldering device, especially an electric soldering device.

According to the conventional structure of a soldering device, the "Improved Structure of a Suction Device" issued by the Bureau of the General Administration of the People's Republic of China on March 21, 1997, which is approved by the No. 301262, which is composed of an upper tube and a lower tube. The body is connected to each other, and a lower portion of the upper tube body is formed with an axial through hole for the shaft to be inserted and a radial through hole for providing the suction seat, and a spring is disposed on the shaft penetrating the lower tube body. The piston is pressed downward by the button provided at the end of the shaft, so that the slot on the shaft is engaged by the suction seat, and when the suction button on the outer side of the suction seat is pressed, the shaft is released by the spring Boost and achieve the effect of attracting tin.

Looking at the above-mentioned conventional structure, it is not difficult to find that there are still some shortcomings. The main reason is as follows: When the conventional structure is used, the shaft must be pressed down and snapped to position the piston to sink and compress the spring. Then press the side of the suction button to release the shaft, and use the spring to stretch back, so that the displacement of the piston produces a negative pressure attraction, so as to achieve the effect of suction, so that the structure must be repeated to press the shaft and suck the tin The button makes the structure more inconvenient to use, greatly reduces the work efficiency, and the instantaneous rebound of the shaft rises, and there is a doubt that jumping out of the long-term use, and lack of practicality.

In view of this, the creator has been engaged in the manufacturing development and design of related products for many years. Experience, after the detailed design and careful evaluation of the above objectives, will ultimately be a practical creation.

The magnetic block 30 is received between the cavity 21 of the electromagnet 20 and the lower chamber 12 of the housing 10, and the upper end portion has a rail plate 31 extending therefrom. The limiting guide hole 22 is disposed, and the blocking block 32 is fixed on the outer portion of the electromagnet 20. The bottom portion is provided with a combination portion 33, and an elastic member 40 is received in the lower chamber 12. The upper end portion of the elastic member 40 is received by the electromagnet 20, and the upper end portion of the piston member 50 has a combined rod member 51 and a combined portion 33 of the bottom portion of the magnetic block 30. The upper end portion of the elastic member 40 is coupled to the upper portion of the elastic member 40, and the outer peripheral portion of the piston member 50 is tightly covered with the inner wall of the lower chamber 12.

On the other hand, when the user releases the switch 23 to lose the electric power of the electromagnet 20, the rebound of the elastic member 40 causes the piston member 50 to abut down while the magnetic block 30 is pulled down to return to the non-energized state. At the normal position, it is used for the next job of attracting and removing tin.

For another embodiment of the structure, please refer to FIGS. 7 and 8 together with the figures 9 and 10.

The electric heating inner tube 61 is electrically connected to the switch 23 for cutting operation, and then the outer tube 62 is sleeved outside the electric heating inner tube 61, and the bottom of the outer tube 62 is assembled with the connecting cover 63, and is mounted on the lower chamber 12 port of the housing 10 via the connecting cover 63. The suction tube 64 is disposed through the electric heating inner tube 61. The heat is transmitted from the electric heating inner tube 61 to the suction tube 64, and one end of the suction tube 64 is protruded from the electric heating inner tube 61 to form a contact end 641, and the other end extends to the connecting cover 63, thereby completing the removal. The tin unit 60 is replaced.

When the above embodiment is used, the electric heating inner tube 61 is controlled by the switch 23 to generate high-temperature heat energy, and the temperature is transmitted to the suction tube 64, and the solder is melted and removed by the contact end 641 protruding from the electric heating inner tube 61.
