Auto-darkening welding helmet with a touchable operating screen
An auto-darkening welding helmet includes a helmet housing; a headband structure connected to the helmet housing; an auto-darkening filter provided on the helmet housing; and an adjustment device by which operating parameters of the auto-darkening filter are adjustable, wherein the adjustment device is a touchable operating screen which faces towards an operator after the operator wears the welding helmet.
1. An auto-darkening welding helmet, comprising:
a helmet housing;
a headband structure connected to the helmet housing;
an auto-darkening filter provided on the helmet housing, the auto-darkening filter comprising a liquid crystal panel; and
a touchscreen configured to receive a touch input on the touchscreen to set operating parameters of the auto-darkening filter, wherein:
the touchscreen is disposed directly adjacent to the liquid crystal panel in the auto-darkening filter such that an operator can manipulate the touchscreen only when the auto-darkening welding helmet is not worn on a head of the operator, and
the touchscreen faces towards the operator while the auto-darkening welding helmet is worn by the operator.
2. The auto-darkening welding helmet as recited in claim 1 , wherein the touchscreen is integrated with the auto-darkening filter.
3. The auto-darkening welding helmet as recited in claim 1 , wherein the touchscreen is provided on an inner surface of the helmet housing.
4. The auto-darkening welding helmet as recited in claim 2 , wherein the touchscreen is located on a rear side of a body of the auto-darkening filter.
5. The auto-darkening welding welding helmet as recited in claim 1 , wherein the operating parameters of the auto-darkening filter which are adjustable by the touchscreen comprise SHADE, SENSITIVITY, DELAY TIME, WELDING TIME, and operation modes including WELD, GRIND, and CUTTING.
6. The auto-darkening welding helmet as recited in claim 5 , wherein the SHADE can be adjusted between 5 and 13 levels, the SENSITIVITY can be adjusted between 0 and 10 levels, and the DELAY TIME can be adjusted between 0 and 10 levels.
7. The auto-darkening welding helmet as recited in claim 1 , wherein the touchscreen comprises a color display screen, a monochromatic display screen, or a black and white display screen.
8. The auto-darkening welding helmet as recited in claim 1 , wherein the touchscreen is a resistance-type or capacitance-type touchable screen.
9. The auto-darkening welding helmet as recited in claim 1 , wherein an “unlock/lock” key is provided on the auto-darkening filter such that the touchscreen can be activated in a working state or locked in a sleep state by pressing the “unlock/lock” key.
10. A method for manipulating an auto-darkening welding helmet, the method comprising:
receiving, via a touchscreen in the auto-darkening welding helmet, a touch input on the touchscreen from an operator; and
in response to receiving the touch input, setting operating parameters of an auto-darkening filter of the auto-darkening welding helmet, wherein the auto-darkening welding helmet comprises:
a helmet housing,
a headband structure connected to the helmet housing,
the auto-darkening filter provided on the helmet housing, the auto-darkening filter comprising a liquid crystal panel, and
the touchscreen configured to receive the touch input and disposed directly adjacent to the liquid crystal panel in the auto-darkening filter such that the touchscreen can be manipulated only when the auto-darkening welding helmet is not worn on a head of the operator.
11. The method of claim 10 , wherein the touchscreen is integrated with the auto-darkening filter.
12. The method of claim 11 , wherein the touchscreen is located on a rear side of a body of the auto-darkening filter.
13. The method of claim 10 , wherein the touchscreen is provided on an inner surface of the helmet housing.
14. The method of claim 10 , wherein the touchscreen comprises a color display screen, a monochromatic display screen, or a black and white display screen.
15. The method of claim 10 , wherein the touchscreen is a resistance-type or capacitance-type touchable screen.
16. The method of claim 10 , wherein an “unlock/lock” key is provided on the auto-darkening filter such that the touchscreen can be activated in a working state or locked in a sleep state by pressing the “unlock/lock” key.
17. The method of claim 10 , wherein:
receiving the touch input from the operator comprises detecting the touch input on the touchscreen; and
the touch input includes one of a sliding or pressing motion.
18. The auto-darkening welding helmet of claim 1 , wherein:
the touchscreen is configured to receive the touch input by detecting the touch input on the touchscreen; and
the touch input includes one of a sliding or pressing motion.
