Abstract
The utility model discloses an electrowelding mask capable of controlling opening and closing of a light filter eyeglass through swing of the head. The electrowelding mask is characterized in that an eyeglass opening and closing device and a control circuit are additionally arranged on the basis of a common head-mounted electrowelding mask. A self-locking circuit is switched on through adoption of a touch switch. The self-locking circuit stimulates a switch circuit and enables the switch circuit to be switched on. The switch circuit is connected with two time relays. One time relay is used for controlling the conduction time of an electromagnetic coil. Magnetic force generated from the electromagnetic coil is utilized to drive magnets on the protective eyeglass and enable the lens to be opened or closed. The other time relay is used for controlling an unlocking circuit and enabling an integral circuit to be in an initial state. The electrowelding mask is simple in structure, reasonable in design, easy to manufacture, rapid in motion and sensitive in response.

The specific embodiment
Most preferred embodiment of the present utility model is such, and with reference to accompanying drawing 1～5, filter glass 1 left end is connected with the second connecting axle 5, is connected rotating shaft 6 left ends between the second connecting axle 5 and the 3rd connecting axle 8, and the 3rd connecting axle 8 connects again the gimbal lever 18 and the second Magnet 9.Filter glass 1 right-hand member is connected with the 4th connecting axle 15 again, be connected rotating shaft 6 right-hand members between the 4th connecting axle 15 and the 5th connecting axle 16, the 5th connecting axle 16 other ends are connected with the gimbal lever 18, first connecting axle 4 one termination the first Magnet 2, another termination filter glass 1 left side.Solenoid 3 is fixed on the lower left in common head-wearing electric welding cover window 14 left sides.The first rotating shaft support 7 one ends are fixed on common head-wearing electric welding cover window 14 lower lefts, and the left side of rotating shaft 6 is passed in other end boring in the hole.The second rotating shaft support 17 1 ends are fixed on common head-wearing electric welding cover window 14 lower rights, and the right of rotating shaft 6 is passed in other end boring in the hole.Circuit board and power supply and Swinging switch combination 11 are connected to the back of common head-wearing electric welding cover 13 through the 6th connecting axle 12.
As shown in Figure 6, swing head Swinging switch 19 is engaged, as long as instantaneous joint just can make latching circuit 20 self-lockings, until release., the electric current of latching circuit 20 output is very little, can only gauge tap circuit 21, and make on-off circuit 21 connect main power.
Main power through on-off circuit 21 connects respectively two time relays.Very first time relay 22 is controlled the conduction time of solenoid 3.Second time relay 23 is controlled release circuit 24, and release circuit 24 makes circuit be placed in original state.
as shown in Figure 2, when solenoid 3 does not have electric current to pass through, the first Magnet 2 is adsorbed on the iron core of solenoid 3, when solenoid 3 has electric current to pass through, iron core just has magnetic field, suppose that magnetic field unshakable in one's determination is S under upper N, the first Magnet 2 is N under upper S, inhale mutually according to heteropole, the homopolar-repulsion principle, upper N unshakable in one's determination will repel the lower N of the first Magnet 2, the first Magnet 2 is broken out, the first Magnet 2 is connected with filter glass 1 through the first connecting axle 4, so filter glass 1 also will be broken out, urge out rear solenoid 3 outages of filter glass 1, under effect of inertia, filter glass 1 is always around rotating shaft 6 rotations, until the second Magnet 9 contacts (as Fig. 3) with the iron core of solenoid 3.This moment, filter glass 1 was opened.
As shown in Figure 3, suppose that the second Magnet 9 is N under upper S, when solenoid 3 had electric current to pass through, the magnetic field unshakable in one's determination of solenoid 3 was S under upper N, and lower S unshakable in one's determination repels the upper S of the second Magnet 9.Filter glass 1 is closed (as Fig. 2).As long as the pendulum yaw, solenoid 3 energisings, filter glass 1 is opened again.Yaw again, filter glass 1 is closed, so repeatedly.
