Definitions

  • the present invention relates to snorkeling equipment. More specifically, the present invention relates to a full-face snorkel mask which provides two discrete channels for air intake and air exhaust respectively, so that a user is adapted for natural breathing through the nose and/or mouth by inhaling fresh air through the fresh air intake channel and discharging waste air through the exhaust air discharging channel in a separated manner.
  • Snorkeling is one of the most popular recreational activities. There is no training required with snorkeling, wherein people can grab a goggle and a snorkel tube and hop in the water and go.
  • the goggle and snorkel tube allow the user to breathe while face down on the surface of the water.
  • the goggle and the snorkel tube are always separated from each other so that the user must attach the goggle and the snorkel tube separately.
  • the user must individually adjust the goggle and the snorkel tube.
  • Another problem is that the user must bite down the mouthpiece of the snorkel tube so that the lips of the user can seal around it and hold the snorkel tube in place.
  • the mouthpiece is uncomfortable and unhygienic.
  • the user may get choke when water leaks into the user's mouth from time to time from the top opening end of the snorkel tube and/or through the mouthpiece thereof.
  • the snorkel tube is a single tubular channel device that the user inhales fresh air and exhales waste air at the same channel. The user may accidentally inhale the waste air if the waste air is not totally discharged from the snorkel tube.
  • US 2016/0297505 A1 concerns a diving mask comprising a faceplate secured to a frame, a flexible skirt having a partition delimiting an upper viewing chamber from a lower breathing chamber, a snorkel having an inlet channel for inhaled air and at least one escape channel for exhaled air, the said snorkel being a continuation of the upper part of the frame, the inlet channel for inhaled air leading into the upper chamber, whilst the first escape channel for exhaled air communicates with the lower chamber.
  • Similar diving masks are disclosed in CN 204173146 U , CN 106428476 A and CN 205469729 U .
  • An improved snorkel equipment is provided to integrate the goggle and the snorkel tube together in order to form a full-face snorkel mask, wherein the snorkel mask covers the entire face of the user from the forehead to the chin.
  • a sealed chamber is formed after the snorkel mask is worn and the snorkel tube is integrated with the snorkel mask to communicate with the sealed chamber. Therefore, the user is able to breathe in and out through the sealed chamber via the snorkel tube.
  • the full-face snorkel mask cannot solve the water leaking problem from the snorkel tube into the sealed chamber.
  • Goggle fog is always caused when the user exhales warm waste air into the sealed chamber. Meanwhile, the exhaust air will be accumulated within the sealed chamber, so that the user will inevitably breathe in the exhaust air in sealed chamber instead of fresh air from the snorkel tube. It will cause dizziness and nausea when repeatedly inhaling the exhaust air from the sealed chamber.
  • the conventional snorkel equipment is not designed to maintain breathing capabilities in a comfort manner and vision capabilities at the same time.
  • An object of the present invention is to provide a full-face snorkel mask according to claim 1 which solves the problems of conventional snorkel equipment.
  • a full-face snorkel mask comprises a mask assembly adapted for extending peripherally in a sealing engagement with a face of a user, wherein the mask assembly has an air intake chamber and a breathing chamber isolated from the air intake chamber when the mask assembly is worn.
  • the full-face snorkel mask further comprises a snorkel assembly which has a fresh air intake channel communicating with the air intake chamber for guiding fresh air thereinto and an exhaust air discharging channel communicating with the breathing chamber for discharging waste air therefrom.
  • the fresh air intake channel and the exhaust air charging channel are two discrete channels respectively, so that the user is adapted for natural breathing through the nose and/or mouth by inhaling fresh air through the fresh air intake channel and discharging waste air through the exhaust air discharging channel in a separated manner.
  • a vision section of the mask assembly is located at the air intake chamber.
  • the warm waste air exhaled by the user is guided to discharge from the breathing chamber to the exhaust air discharging channel right away to prevent the warm waste air entering to air intake chamber, so that the vision section of the mask assembly will not be fogged up by the warm waste air exhaled by the user at the breathing chamber.
  • the mask assembly has a V-shaped face seal for sealing against the user's face and across the nose bridge thereof to not only let the user to wear the mask assembly in a comfortable way but also seal between the air intake chamber and the breathing chamber so as to prevent air being leaked from the breathing chamber to the air intake chamber.
  • one or more first non-return valves are provided at the mask assembly to only allow the fresh air entering from the air intake chamber to the breathing chamber. Therefore, once the waste air exhaled by the user is guided to discharge from the breathing chamber, the user always breathes in the fresh air at the breathing chamber from the air intake chamber via the first non-return valves.
  • the full-face snorkel mask further comprises a purge valve provided at the mask assembly for clearing water that enters the mask assembly.
  • the water prevention valve comprises a floatable member provided at the top end of the snorkel assembly to seal at the fresh air intake channel/the exhaust air discharging channel when the top end of the snorkel assembly is submerged below water.
  • the full-face snorkel mask is constructed to have two discrete chambers and two discrete channels to separate the fresh air and the waste air when the user breathes.

  • the V-shaped face seal 140 seals against the user's face and across the nose bridge thereof, the waste air cannot be leaked from the breathing chamber 102 to the air intake chamber 104. Therefore, when the user exhales the waste air at the breathing chamber 102, the waste air cannot enter to the air intake chamber 104. Besides, only fresh air can enter to the air intake chamber 104 from the fresh air intake channel 220. More important, the warm waste air exhaled by the user is guided to discharge from the breathing chamber 102 to the exhaust air discharging channel 230 right away through the air guiding channel 106 to prevent the warm waste air entering to air intake chamber 104 accidentally. Therefore, the warm waste air will never enter to the air intake chamber 104. As a result, the vision section 118 of the mask assembly 100, which is located at the air intake chamber 104, will not be fogged up by the warm waste air exhaled by the user at the breathing chamber 102.
