Description of Related Arts
[0002] 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. In particular, 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. As a result, 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. However, the mouthpiece is uncomfortable and unhygienic. The user,
especially for the beginner 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. More importantly, 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.
[0003] 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.
[0004] 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. However, 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.
[0005] Therefore, the conventional snorkel equipment is not designed to maintain breathing
capabilities in a comfort manner and vision capabilities at the same time.
Summary of the Present Invention
[0006] 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.

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.
[0009] According to a preferred embodiment of the present invention, 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.
[0010] According to a preferred embodiment of the present invention, 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.
[0011] According to a preferred embodiment of the present invention, 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.
[0012] According to a preferred embodiment of the present invention, 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.
[0013] According to a preferred embodiment of the present invention, the full-face snorkel
mask further comprises a purge valve provided at the mask assembly for clearing water
that enters the mask assembly.
[0014] According to a preferred embodiment of the prevent invention, water cannot be entered

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.
[0015] 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. With
such simplified structural configuration, the full-face snorkel mask provides multiple
functions of preventing the user repeatedly inhaling back the waste air and minimizing
the vision section of the mask assembly being fogged up. The full-face snorkel mask
of the prevent invention can maintain breathing capabilities in a comfort manner and
vision capabilities at the same time.
[0016] Still further objects and advantages will become apparent from a consideration of

[0021] The present invention provides a full-face snorkel mask for a user according to an
embodiment is disclosed. The full-face snorkel mask comprises a mask assembly 100
adapted for extending peripherally in a sealing engagement with a face of the user,
a head securing device 400 provided at the mask assembly 100 for securing the mask
assembly 100 to the user's head, and a snorkel assembly 200 upwardly extended from
the mask assembly 100. In general, when the mask assembly 100 is worn, the mask assembly
100 of the present invention covers the entire face of the user from the forehead
to the chin.
[0022] Reference is now made to certain specific non-limiting embodiment as shown in Figures.
Figures 1 and 2 depict the full-face snorkel mask. The mask assembly 100 comprises
a full face outer shell 110 for covering the user's face and a half face inner shell
120 attached thereinto for covering the user's nose and mouth. Specifically, the full
face outer shell 110 comprises an outer peripheral shell rim 112, a transparent visor
114 coupled at the outer shell rim 112, and an inner peripheral shell rim 116 coupled
at the outer peripheral shell rim 112.
[0023] The outer peripheral shell rim 112 is sized and shaped for fitting the face of the
user, wherein the inner peripheral shell 116 is coupled at an inner side of the outer
peripheral shell rim 112. It is preferred that the outer peripheral shell rim 112
is made of rigid material and the inner peripheral shell 116 has a face seal, preferably
made of silicone, to seal against the user's face. The transparent shell 114 is preferably
made of shatterproof and polycarbonate. A vision section 118 is defined at the transparent
shell 114 to provide a 180 degree field of vision. The mask assembly 100 further comprises
a camera mount 130 provided at a top end thereof for incorporating with an action
camera, such as "GoPro" camera. It is preferred that the camera mount 130 is provided
at the top-center portion of the outer peripheral shell rim 112 at the position in
front of the snorkel assembly 200.
[0024] The half face inner shell 120, having a concave shape, is coupled to the inner peripheral
shell 116, wherein a top edge of the half face inner shell 120 is extended across
the bridge of the nose of the user and a bottom edge of the half face inner shell

[0025] The head securing device 400 comprises one or more length-adjustable straps 410 attached
to the mask assembly 100. A plurality of strap slots 420 are provided at the outer
peripheral shell rim 112. In the embodiment, each of the straps 410 is made of stretchable
and lightweight synthetic fibers, such as "Spandex", wherein two ends of each straps
410 are attached to the outer peripheral shell rim 112 through the strap slots 420,
so that the user is able wear the mask assembly 100 via the straps 410 in a comfortable
way.
[0026] The mask assembly 100 further has a breathing chamber 102 defined at a space within
the half face inner shell 120, i.e. between the half face inner shell 120 and the
user's face, wherein the user breathes in and out through the breathing chamber 102
when the mask assembly 100 is worn.
[0027] The mask assembly 100 further has an air intake chamber 104 isolated from the breathing
chamber 102, wherein the air intake chamber 104 is formed between the full face outer
shell 110 and the half face inner shell 120. It is appreciated that the vision section
118 is located at the air intake chamber 104.
[0028] Figures 1 to 4 depict that the snorkel assembly 200 comprises a snorkel body 210
upwardly extended from the outer peripheral shell rim 112 of the mask assembly 100,
wherein the snorkel body 210 has two end-to-end channels forming a fresh air intake
channel 220 and an exhaust air discharging channel 230 respectively. The fresh air
intake channel 220 and the exhaust air discharging channel 230 are extended parallelly
and upwardly.
[0029] The fresh air intake channel 220 is arranged for guiding fresh air into the breathing
chamber 102, wherein the fresh air is sucked from outside into the fresh air intake
channel 220 and then to the breathing chamber 102 when the user inhales. The exhaust
air discharging channel 230 communicates with the breathing chamber 102 for discharging
waste air therefrom after the user exhales.
[0030] It is worth mentioning that the breathing chamber 102 and the air intake chamber
104 are two discrete chambers that air cannot pass from one to another when the mask
assembly 100. A V-shaped face seal 140 is extended along the top edge of the half
face inner shell 120 for sealing against the user's face and across the nose bridge
thereof to prevent the waste air being leaked from the breathing chamber 102 to the
air intake chamber 104. It is preferred that the V-shaped face seal 140 is made of
silicone for tight-fitting and sealing against the user's face, so as to seal and
separate the breathing chamber 102 from the air intake chamber 104.
[0031] In order to communicate the breathing chamber 102 with the air intake chamber 104,
the full-face snorkel mask of the present invention further comprises a valve assembly
300. In one embodiment, the valve assembly 300 comprises one or more first non-return
air valves 310 provided at the mask assembly 100 for only allowing the fresh air at
the air intake chamber 104 from the fresh air intake channel 220 entering to the breathing
chamber 220 and for preventing the waste air entering to the air intake chamber 104.
In one embodiment, two first non-return air valves 310 are provided at the half face
inner shell 120 below two side ends of the V-shaped face seal 140 respectively.
[0032] Figure 7 depicts the airflow of the full-face snorkel mask of the present invention.
When the user inhales, the fresh air is sucked from the fresh air intake channel 220
to the air intake chamber 104. Then, the fresh air passes through the first non-return
air valves 310 and enters into the breathing chamber 102. When the user exhales, the
user releases the waste air at the breathing chamber 102. Due to the air pressure
increase at the breathing chamber 102, the waste air is forced out of the breathing
chamber 102 to the exhaust air discharging channel 230 for discharging waste air from
the breathing chamber 102 after the user exhales.
[0033] The mask assembly 100 further has an air guiding channel 106 formed at a peripheral
portion of the mask assembly 100 and extended from the breathing chamber 102 to the
exhaust air discharging channel 230 for guiding the waste air being discharged from
the breathing chamber 102 to the exhaust air discharging channel 230. In one embodiment,
the air guiding channel 106 is formed between the outer peripheral shell rim 112 and
the inner peripheral shell rim 116.
[0034] While 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.
[0035] Referring to Figure 4 of the drawings, the valve assembly 300 further comprises a
second non-return air valve 320 provided at the exhaust air discharging channel 230
for preventing the waste air at the exhaust air discharging channel 230 being returned
back to the breathing chamber 102. As it is mentioned above, the first non-return
air valve 310 only allows the fresh air entering to the breathing chamber 220 from
the air intake chamber. The second non-return air valve 320 only allows the waste
air discharging out of the exhaust air discharging channel 230 to prevent the backflow
of the waste air along the exhaust air discharging channel 230. Therefore, the first
and second non-return air valves 310 and 320 will ensure the airflow of the air within
the mask assembly 100.
[0036] Referring to Figure 5 of the drawings, the snorkel body 210 further has two air passages
240 and 250 discretely formed at a top end of the snorkel body 210, wherein the air
passages 240 and 250 are extended parallelly and upwardly.
[0037] Two top openings of the air passages 240 and 250 communicate with the fresh air intake
channel 220 and the exhaust air discharging channel 230 respectively. In one embodiment,
each of the air passages 240 and 250 further has a rear opening to communicate with
outside, wherein the top openings of the air passages 240 and 250 are located above
the rear openings thereof.
[0038] Referring to Figures 4 and 5, the valve assembly 300 further comprises a water prevention
valve 330 provided at the snorkel assembly 200 for preventing water entering into
the fresh air intake channel 220 and the exhaust air discharging channel 230 when
the snorkel assembly 200 is submerged below water. In one embodiment, the water prevention
valve 330 is provided at each of the air passages 240 and 250.
[0039] Specifically, the water prevention valve 330 comprises a floatable member 340 movably
disposed at each of the air passages 240 and 250. When the snorkel assembly 200 is
submerged below water, water will enter into the air passages 240 and 250 through
the rear openings thereof. The floatable members 340 float and seal at the top openings
of the air passages when the snorkel assembly 200 is submerged below water in order
to prevent water entering into the fresh air intake channel 220 and the exhaust air
discharging channel 230. When the top end of the snorkel assembly 200 is located above
water, water in the air passages 240 and 250 are drained out through the rear openings
thereof. Therefore, the floatable members 340 drop down by their own weight at the
air passages 240 and 250 respectively when the top end of the snorkel assembly is
located above water in order to open up the top openings of the air passages 240 and
250. Once the top openings of the air passages 230 are opened, fresh air is guided
to enter into the corresponding air passage 240 at the rear opening thereof and is
then guided to enter into the fresh air intake channel 220. Meanwhile, exhaust air
can be discharged from the exhaust air discharging channel 230 to the corresponding
air passage 250 to outside through the rear opening thereof.
[0040] In one embodiment, each of the floatable members 340 has a conical shape that bases
of the floatable members 340 upwardly face toward the top openings of the air passages
respectively and apexes of the floatable members 340 face downwardly. It is appreciated
that the diameter size of the base of the floatable member 340 is larger than that
of the apex thereof. Once the water fills into the air passages 240 and 250, the floatable
members 340 provide enlarged contacting surfaces for being upwardly pushed by the
water to ensure the floatable members 340 being floated properly within the air passages
240 and 250. It should be appreciated that the floatable members 340 are two weighting
members being naturally dropped down by gravity when there is no water in the air
passages 240 and 250.
[0041] The water prevention valve 330 further comprises two sealing rings 350 coupled at
the top openings of the air passages 240 and 250 to seal and engage with the floatable
members 340 when the snorkel assembly 200 is submerged below water. In other words,
the floatable members 340 upwardly float and seal at the sealing rings 350 to close
the fresh air intake channel 220 and the exhaust air discharging channel 230.
[0042] Referring to Figures 2 to 4 of the drawings, the snorkel assembly 200 further comprises
a top snorkel cap 260 coupled at the top end of the snorkel body 210, wherein the
top snorkel cap 260 has two individual air chambers 262 and 264 that one of the air
chambers 262 communicates between the fresh air intake channel 220 and one of the
air passages 240 and another air chamber 264 communicates between the exhaust air
discharging channel 230 and another air passage 250. It is appreciated that the air
chambers 262 and 264 of the top snorkel cap 260 are considered as two airflow detouring
paths, wherein the fresh air is detoured 180 degrees from the air passage 240 to the
fresh air intake channel 220 while the waste air is detoured 180 degrees from the
exhaust air discharging channel 230 to the air passage 250. These airflow detouring
paths will eliminate water entering into the fresh air intake channel 220 and the
exhaust air discharging channel 230 from the air passages 240 and 250 when the snorkel
assembly 200 is submerged below water.
[0043] Referring to Figures 3, 4 and 6 of the drawings, for achieving a better sealing effect,
the snorkel assembly 200 further comprises a sealing element 270 mounted and sealed
between the top snorkel cap 260 and the top end of the snorkel body 210. The sealing
element 270 has four sealing openings 272, 274, 276, and 278 aligned with the fresh
air intake channel 220, the exhaust air discharging channel 230, and the air passages
240 and 250 respectively to prevent any water and air leakage between the top snorkel
cap 260 and the snorkel body 210.
[0044] The valve assembly 300 further comprises a purge valve 360 provided at a bottom side
of the mask assembly 100 for clearing water that enters the mask assembly 100.
[0045] According to the present invention, the user is able to wear the full-face snorkel
mask for snorkeling, wherein the user can natural breath through the nose and/or mouth
by inhaling fresh air through the fresh air intake channel 220 and discharging waste
air through the exhaust air discharging channel 230 in a separated manner. During
snorkeling, the top end of the snorkel assembly 200 is located above water. Then,
the floatable members 340 drop down by their own weight at the air passages 240 and
250 respectively to open up the fresh air intake channel 220 and the exhaust air discharging
channel 230. Fresh air is supplied from the rear opening of one of the corresponding
air passages 240 to the fresh air intake channel 220, to the air intake chamber 104,
and then to the breathing chamber 102 via the first non-return valve 310. Therefore,
the user is able to breathe in the fresh air within the breathing chamber 102. Meanwhile,
when the user breathes out the waste air to the breathing chamber 102, the waste air
is forced out of the breathing chamber 102 to the air guiding channel 106, to the
exhaust air discharging channel 230, and to the corresponding air passage 250. Then,
the waste air is discharged from the rear opening of the air passage 250. Therefore,
the present invention provides a one-in-on-out airflow configuration in a single tubular
structure, i.e. the snorkel body 210 with the fresh air intake channel 220 and the
exhaust air discharging channel 230, to separate the fresh air and the waste air,
so as to prevent the user from repeatedly inhaling the waste air in the breathing
chamber 102.
[0046] Once the snorkel assembly 200 is submerged below water, the floatable members 340
float and seal at the top openings of the air passages 240 and 250 to close the fresh
air intake channel 220 and the exhaust air discharging channel 230, so as to prevent
water entering thereinto.
[0047] One skilled in the art will understand that the embodiment of the present invention
as shown in the drawings and described above is exemplary only and not intended to
be limiting.
[0048] It will thus be seen that the objects of the present invention have been fully and
