Description

Technical Field

[0001] This utility model relates to the field of welding masks, specifically a visual welding mask. Background Technology

[0002] With the development of modern industrial technology, electric welding, a high-temperature fusion technology, is increasingly used in daily life and industrial production. Because high-temperature welding generates significant ultraviolet radiation, operators need to wear welding masks to avoid skin burns and vision damage. However, conventional welding masks are not completely black, making them inconvenient to wear. In recent years, welding masks using LCD displays have emerged. Compared to conventional masks, LCD masks have high transmittance when not powered on, facilitating observation. When powered on, the transmittance of the LCD mask rapidly decreases, protecting the user from strong light damage, making it very convenient. These advantages have led to a rapid increase in the market share of LCD masks.

[0003] In existing technologies, liquid crystal displays on liquid crystal masks generally employ a sandwich structure, with a layer of liquid crystal molecules sandwiched between two transparent substrates. When an electrical signal is applied to the upper and lower substrates, the liquid crystal molecules deflect under the influence of the electric field, thereby changing the propagation path of polarized light rays incident on the liquid crystal cell, thus altering the amount of light transmitted and achieving the purpose of controlling brightness.

[0004] In existing technologies, when the temperature is low, the breath exhaled by the person wearing the welding mask comes into contact with the LCD screen, which will generate a large amount of water mist on the LCD screen. When the person is welding, the water mist will seriously affect the person's observation. The person needs to remove the welding mask frequently to wipe the water mist off the LCD screen, which results in low work efficiency and inconvenience for the person's actual use.

[0032] Example 3

[0033] Based on Embodiment 2, a pull plate 21 is provided to facilitate subsequent maintenance by personnel. One end of the pull plate 21 is stuck in the slide groove 19, and the pull plate 21 can slide along the slide groove 19. The pull plate 21 has an "I" shaped plate structure. A locking block 22 is fixedly connected to the pull plate 21. The locking block 22 has a square plate structure and can be locked into the locking groove 18 opened on the mounting plate 16. The locking groove 18 has a square groove structure. Personnel can pull the pull plate 21 to make the pull plate 21 and the locking block 22 slide along the slide groove 19, so that the thrust spring 20 is compressed and the locking block 22 slides out of the locking groove 18.

[0034] The LCD display 8 is fixedly mounted on the fixed frame 2. The fixed frame 2 has a sliding groove 19 with a convex groove structure. A thrust spring 20 is installed in the sliding groove 19. One end of the thrust spring 20 is fixedly connected to the pull plate 21, and the other end of the thrust spring 20 is fixedly connected to the fixed frame 2. The fixed frame 2 is fixedly mounted on the mask body 1. A cooling fan 3 is fixedly mounted on the mask body 1.

[0035] The fixing block 12 has a square plate structure and is fixedly connected to the movable plate 10. The movable plate 10 is fixed to the limiting plate 9 by screws. An absorbent cloth 11 is fixedly connected to the movable plate 10 and contacts the surface of the LCD display 8. The operator can unscrew and remove the screws on the limiting plate 9 to remove the movable plate 10 and dry the absorbent cloth 11 on the movable plate 10. During installation, the operator can insert the assembly of the movable plate 10 and the absorbent cloth 11 into the gap between the LCD display 8 and the limiting plate 9, and make one end face of the movable plate 10 contact the limiting block 7, and make the side of the fixing block 12 contact the side of the limiting plate 9 to complete the positioning. Align the hole on the limiting plate 9 with the threaded hole on the movable plate 10, and the operator can thread the screw through the hole on the limiting plate 9 and the threaded hole on the movable plate 10 to connect them, and then install the movable plate 10 on the limiting plate 9.

[0036] In actual use, the screw 6 is rotated along the threaded hole on the limiting block 7, causing the limiting block 7, the limiting plate 9, and the moving plate 10 to slide back and forth along the limiting groove 5. The water-absorbing cloth 11 fixedly connected to the moving plate 10 can then wipe away the fog on the LCD display 8. Personnel do not need to remove the mask body 1 and manually wipe away the water fog on the LCD display 8, which is convenient for personnel to use. This avoids the fog on the LCD display 8 affecting personnel's observation during the welding process, improves personnel's work efficiency, and ensures that the device can be used normally at lower temperatures. Furthermore, by installing an external protective mirror 15 on the fixed frame 2, the LCD display 8 can be protected, preventing impurities that splash during welding from directly colliding with the LCD display 8 and causing damage to it.
