Protection devices for personal use against accidents, namely, motorcycle helmets; protective helmets; solderers' helmets; protective masks for workers; filters for non-medical respiratory masks; protective masks, namely, protective face masks not for medical purposes; anti-glare visors for protective helmets; breathing apparatus, except for artificial respiration, namely, regulators for use in scuba diving; protective goggles for sports
A welding mask (10) comprises a mask housing (11), and a hood (40)for being worn on the head of a wearer and made from a non-breathable soft material. A zipper structure (42, 52, 56) for detachably connecting the hood to the mask housing around the whole periphery of an opening of the mask housing is disposed between the mask housing (11) and the hood (40). After the hood and the mask housing are connected, the zipper structure is located inside the welding mask housing.
Disclosed is a lock-catch fitting structure of an electric air-purifying respirator of an auto-darkening welding mask. The electric air-purifying respirator comprises a housing (10) and a battery device. A battery holder is arranged on the housing (10), and by virtue of the lock-catch fitting structure, the battery device is detachably installed in the battery holder. The lock-catch fitting structure comprises at least four pairs of sliding engagement structures respectively formed on the battery device and on the battery holder, and a locking structure arranged in the battery device. Engagement or disengagement of each of the sliding engagement structure pairs can be formed by the sliding thereof relative to each other. The locking structure comprises a button (80) and a locking tongue (85) actuated by the button (80). The moving direction of the locking tongue (85) is perpendicular to the sliding direction of the sliding engagement structures. After the sliding engagement structure pairs move relative to each other and are in position, the locking tongue (85) contacts a stop face (103) of the battery holder, so that the sliding engagement structure pairs are locked.
A wireless projection type auto-darkening welding mask (1) and a welding device equipped with the wireless projection type auto-darkening welding mask (1). The wireless projection type auto-darkening welding mask comprises: a mask housing (40); a headband structure (60) for fixing the mask housing (40); an auto-darkening filter (10) fixed to the mask housing (40); a wireless communication module (100a); and a miniature projector (600) in data connection with the auto-darkening filter (10) and the wireless communication module (100a), wherein when the auto-darkening filter (10) is in a transparent state, the miniature projector (600) is suitable for projecting an operation parameter of the auto-darkening filter (10) and/or data received via the wireless communication module (100a) to a plane in front of the welding mask (1) so as to facilitate observation by a wearer of the welding mask (1).
A welding mask, comprising: a mask casing (40); a head belt structure (60) for fixing the mask casing (40); a head-up display auto-darkening filter (10) fixed on the mask casing (40); and a light-transmitting protection sheet (20') provided in front of the head-up display auto-darkening filter (10) on the mask casing (40); the head-up display auto-darkening filter (10) comprises a head-up display (10c) for displaying various operating parameters of the auto-darkening filter (10); the head-up display (10c) is arranged between the auto-darkening filter (10) body and the protection sheet (20'), such that the operating parameters displayed as emitted light on the head-up display (10c) are imaged to the eyes of a wearer of the welding mask through the protection sheet (20') when the auto-darkening filter (10) is in a transparent state.
