After good, mask shell 20 can block the entire face of operator.Substantially rectangular opening 21 is offered on mask shell 20.
One retainer 30 can be releasably mounted in the opening 21.One automatic beam change can be releasably installed on retainer 30
Filter 40.
Automatic beam change filter 40 consists essentially of liquid crystal display panel 41, in the control of the control circuit of automatic beam change filter 40
Under system, liquid crystal display panel 41 is generally in the state of light transmission, still, can be dimmed in the moment of the starting the arc, protects operator's with this
Eyes are not by the injury of harm ray.Optical sensor 42 is equipped on the outside side of automatic beam change filter 40, thus rising
The moment of arc receives arc optical signal and control circuit is notified to operate liquid crystal display panel 41.In the outside side of automatic beam change filter 40
On be additionally provided with photoelectric conversion battery 43, for high-intensitive arc light to be converted to electric energy in the starting the arc, automatic beam change mistake is arrived in storage
It is spare in the (not shown) battery of filter 41.Particularly, in the outside of automatic beam change filter 40, one transparency protected 50 can
Releasably it is arranged in opening 21, effect is that the splash for preventing from generating when welding destroys liquid crystal display panel 41.
Auto-changing Shade Welding Mask Made 100 further includes lighting device 60.Lighting device 60 for example may include shell and
The light bulb (especially LED bulb) and battery installed in shell.Lighting device 60 can for example pacify at the top of mask shell 20
Dress, so that the light bulb of lighting device 60 can be towards the front of operator, and light bulb exists after mask 100 is worn in place
Light can get to the front certain distance of mask shell 20 just when electrified light emitting.For example, being set at the top of mask shell 20
There are two fixation holes 22.Two holes 61 also are provided on the shell of lighting device 60.In this way, by by the hole 61 of lighting device 60
It respectively with the fixation hole 22 of mask shell 20 to just, and penetrates a bolt and is tightened bolt with nut, thus by lighting device
60 are fixed on mask shell 20.It will be apparent to those skilled in the art that lighting device 60 also can be set in any other energy
On the position of mask shell 20 enough to provide illuminating ray in front of operator.For example, optionally, lighting device 60 can also be with
It is arranged in beside the transverse direction of opening 21 of mask shell 20, so that light bulb can be towards operator after mask 100 is worn in place
Front.In addition, lighting device 60 also can be with flash lamp detachable in such as camera field and digital camera or folk prescription camera
The mode of connection is connected to mask shell 20.
It also is provided with control circuit in lighting device 60, to control the switch of light bulb.Lighting device 60 further includes button 64,
Enable to directly control the power on/off of the light bulb of lighting device 60.One cable 62 is connected with the control circuit, and the cable
Line 63 is equipped with electric connection 63.As described in Figure 2, it is also formed with a through-hole 23 in mask shell 10, to pacify by lighting device 60
When being filled to mask shell 20, cable 62 and its electric connection 63 can pass through the through-hole 23.
It is additionally provided with a socket 45, on automatic beam change filter 40 so as to receive the electric connection 63.By cable 62,
The control circuit of automatic beam change filter 40 can be connected with the control circuit of lighting device 60, and the former can be used for by
Button 64, which has been pressed so that in the case that the light bulb of lighting device 60 is powered, independently controls the operation of lighting device 60, such as
Keep its light bulb bright or goes out.
Fig. 4 briefly illustrates the control block diagram for automatic beam change filter 40, there it can be seen that automatic beam change mistake
The control circuit of filter 40 can receive arc optical signal from optical sensor 42, and issue activate to liquid crystal display panel 41 accordingly/no
Its instruction is activated, while issuing the instruction for not activating/activating it to lighting device 60.In the control of automatic beam change filter 40
One group of instruction for being able to carry out control method is stored in circuit.The control according to the application is schematically introduced referring to Fig. 5
One embodiment of method.
Firstly, checking whether the button 64 of lighting device 60 has been pressed so that the lamp of lighting device 60 in step S10
Be soaked light.If it is judged that being "No", then continue waiting for.If it is judged that being "Yes", then step S20 is gone to.In step
S20 judges whether to generate arc optical signal.For example, this can be by the control circuit by automatic beam change filter 40 from light sensing
Device 42 reads with the presence or absence of arc optical signal and realizes.If it is determined that result be "No", then continue waiting for.If it is judged that being
"Yes" then goes to step S30.In step S30, liquid crystal display panel 41 is activated.That is, making liquid crystal display panel 41 from light transmission
State is transformed into lighttight state.At the same time, in step S31, so that the light bulb of lighting device 60 does not shine.Then, exist
Step S40 judges that arc optical signal whether there is.If it is judged that being "Yes", then continues to current state and wait.If
Judging result is "No", then goes to step S50.In step S50, so that liquid crystal display panel 41 does not activate.That is, making liquid crystal
Panel 41 is transformed into the state of light transmission from lighttight state.At the same time, in step S51, lighting device 60 can be made
Light bulb shines again.Then, in step S60, judge the button 64 of lighting device 60 whether by button.If it is judged that being
"No" then goes to step S20.If it is judged that being "Yes", then above-mentioned control process terminates.
Using the above method of the application, when the button 64 of lighting device 60 is pressed for the first time so that light bulb shines it
Afterwards, every time while the starting the arc, liquid crystal display panel 41 is always activated with the lamp of the eyes while lighting device 60 of protecting operator
Bubble is automatically switched off, and then, when not having the starting the arc, liquid crystal display panel 41 will not activated automatically while light bulb is opened, and facilitates operation
Person observes the welding situation of welding position at any time during the welding process.
In an optional embodiment, step S40, which can be set into, to be "No" in judging result and waits certain time (example
Such as 1 second) afterwards judging result not yet "No" when, just go to step S50 and S51.In an optional embodiment, lighting device 60
Button 64 can be configured to automatic beam change filter 40 control circuit just in operating lighting means 60 when, lighting device 60
Button 64 can directly disconnect control and switch lighting device 60.
Although lighting device 60 is equipped with battery in an illustrated embodiment, in another alternate embodiment, illumination dress
The battery of automatic beam change filter 40 can also be shared by setting 60.In addition, in an alternative embodiment, also can be omitted illumination dress
The button 64 in 60 is set, as long as in this way, lighting device 60, which is configured to electric connection 63 1, is inserted into inserting for automatic beam change filter 40
Seat 45, then the control circuit of automatic beam change filter 40 just makes the light bulb electrified light emitting of lighting device 60 automatically, pulls up electric mortiser
First 63 allow for light bulb power-off, while method omits step S10 and S60.
In the context of this application, each embodiment can be engaged one another while arbitrarily.Although this is described in detail here
The particular implementation of application, but they are used for the purpose of the purpose explained and provide, and it is not considered that they are to the application
Range be construed as limiting.Under the premise of not departing from the application spirit and scope, various replacements, change and transformation can be contemplated out
Come.
