Abstract
A water-sealing diving-use snorkel without generating a vacuum suction force includes a diving-use snorkel unit connected with an air intake-ventilation nozzle unit comprising an air intake-ventilation pipe, a nozzle plate, at least one housing, a water-sealing membrane, and a float, being orderly sheathed. The water-sealing membrane and the float are sheathed respectively on strip units of the nozzle plate, allowing the water-sealing membrane and the float to slide freely on rails of the strip units. When a water level sinks, a small amount of air can enter into the snorkel unit from a notch on a leak-proof washer below the nozzle plate; therefore, no vacuum suction force will be formed to suck the water-sealing membrane, such that a sense of fear that a user feels unable to breathe can be eliminated.
Description
- a) Field of the Invention
- The present invention relates to a snorkel, and more particularly to a snorkel which can prevent a user from choking in water when a water level ascends, and will not form a vacuum suction force to suck a water-sealing membrane when the water level sinks, so as to eliminate a sense of fear for the user that he or she suddenly feels unable to breathe, thereby improving safety and comfortableness of a diver.
- b) Description of the Prior Art
- A conventional snorkel is a pure J-shape hollow tube. As a tail end of the snorkel is not provided with an automatic water-sealing device, it is provided with a shortcoming that a diver may drink water or his or her bronchus may be choked by water, accidentally.
- Therefore, there are vendors who have installed an automatic water-sealing structure at a tail end of a tube unit of the snorkel, with the primary structure including a housing at the tail end of the tube unit, and an interior of the housing being installed with a one-way membrane valve and a float, such that by an ascending force of the float when the float is in touch water, the one-way membrane valve can be activated to automatically close the valve, thereby preventing the water from flowing into the tube to be sucked into a mouth of a diver or to allow a bronchus of the diver to be choked by the water.
- However, when a water level sinks, a vacuum state will be formed inside the snorkel, and a suction force caused by the vacuum state will suck a water-sealing membrane, such that the valve cannot be opened, and a user will not be able to breathe, which will result in a sense of fear that the user is unable to breathe, thereby causing uncomfortableness to a diver or even endangering safety of the diver.
- The primary object of the present invention is to provide a snorkel which includes an air intake-ventilation nozzle unit formed by an air intake-ventilation pipe, a nozzle plate, a housing, a water-sealing membrane and a float, with the nozzle unit being connected with a tube unit of the snorkel, wherein the water-sealing membrane and the float slide freely a strip-shape rails of the nozzle plate. When a water level ascends, the float will rise up to push the water-sealing membrane to be blocked on a leak-proof washer at a lower rim of the air intake-ventilation nozzle of the nozzle plate, in order to prevent a diver from choking in water. On the other hand, when the water level sinks, as a small amount of air can flow into the tube unit of the snorkel through a notch at one end of the leak-proof washer below the nozzle plate, no vacuum suction force will be formed to suck the water-sealing membrane, which will eliminate a sense of fear that the diver cannot breathe suddenly, thereby improving safety and comfortableness of the diver.
- To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

FIG. 8 shows a schematic view of partial structures of another embodiment of the present invention. - Referring to
FIG. 1 , the present invention comprises a set of diving-use snorkel unit 10 and air intake-ventilation nozzle unit 20, wherein the air intake-ventilation unit 20 is connected with thesnorkel unit 10 to form a respiration passage. - Referring to
FIG. 2 , the air intake-ventilation nozzle unit 20 includes an air intake-ventilation pipe 21, anozzle plate 22, twohousings membrane 25 and afloat 26, which are orderly sheathed and assembled; wherein, thefloat 26 and the water-sealingmembrane 25 can be integrally formed. - An end of the aforementioned air intake-
ventilation pipe 21 is connected with thesnorkel unit 10, the other end is connected with thenozzle plate 22 to form an air intake-ventilation nozzle 211, thenozzle plate 22 is provided with an air suction-ventilation nozzle 221, below thenozzle plate 22 is provided with at least onestrip unit 222, and a lower rim of the air suction-ventilation nozzle 221 is surrounded with a leak-proof washer 223 (as shown inFIG. 5 ). Twohousings ventilation pipe 21 to cover thenozzle plate 22 and the air intake-ventilation nozzle 221, thereby forming a passage of a single opening. Below a passage of the air suction-ventilation nozzle 221 is provided with the water-sealingmembrane 25, with another opposite location of the water-sealingmembrane 25 being disposed with thefloat 26. Through-holes membrane 25 and thefloat 26 are sheathed respectively on thestrip units 222 of thenozzle plate 22, allowing the water-sealingmembrane 25 and thefloat 26 to slide freely on rails of thestrip units 222. On the other hand, the water-sealingmembrane 25 can be installed with a leak-proof gasket 252. - Referring to
FIG. 3 , when a water level ascends, thefloat 26 will rise up by a buoyancy force, and drive the water-sealingmembrane 25 and the leak-proof gasket 252 to block at the air suction-ventilation nozzle 221 of thenozzle plate 22; wherein the leak-proof gasket 252 is blocked on the leak-proof washer 223 at the lower rim of the air suction-ventilation nozzle 221 of thenozzle plate 22, to prohibit the water from entering into thesnorkel unit 10, thereby preventing the user from being choked by the water. - Referring to
FIG. 5 , the lower rim of the air suction-ventilation nozzle 221 of thenozzle plate 22 is provided with the leak-proof washer 223 on which is provided with at least onenotch 2231. Referring toFIG. 4 , when the water level sinks, as molecules of the air are smaller than those of the water, a small amount of the air can enter into thesnorkel unit 10 from thenotches 2231. Therefore, it will not form a vacuum suction force to suck the water-sealingmembrane 25, so as to eliminate a sense of fear to the user that he or she cannot breathe, thereby improving safety and comfortableness of diving. - Referring to
FIG. 6 , if the leak-proof washer 223 at the lower rim of the air suction-ventilation nozzle 221 of thenozzle plate 22 is not provided with thenotches 2231, then the leak-proof gasket 252 of the water-sealingmembrane 25 is provided with airpermeable trenches 2521, such that when the water level sinks, a small amount of the air can enter into thesnorkel unit 10 from thetrenches 2521, to prevent the user from being unable to breathe. - Referring to
FIG. 7 , thenozzle plate 22 is not provided with the strip units, but is provided with at least one through-hole 224, thefloat 26 is not provided with the through-holes, but is provided with at least onestrip unit 262. Thestrip unit 262 is transfixed into the through-holes membrane 25 and thenozzle plate 22 to slide, due to that thefloat 26 rises up by the buoyancy force. Referring toFIG. 8 , thenozzle plate 22 and thefloat 26 are not provided with the strip units, but instead, thenozzle plate 22 is provided with at least one through-hole 224, and the water-sealingmembrane 26 is provided with at least onestrip unit 253. When thefloat 26 rises up by the buoyancy force, the through-hole 261 of thefloat 26 is sheathed below thestrip unit 253, and an upper part of thestrip unit 253 is transfixed in the through-hole 224 of thenozzle plate 22. - Accordingly, the present invention is a snorkel that when a water level sinks, a small amount of air can flow into a snorkel unit, without forming a vacuum suction force to suck a water-sealing membrane, thereby eliminating a sense of fear for a user that he or she feels unable to breathe.
- It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
