Description

Cylinder and full face mask including the same

The present invention relates to a full face mask to which cylinders are coupled, and more particularly, to a full face mask in which an automatic valve device is inserted into a cylinder and a cylinder is replaced to replace a snorkel device and a chemical filter device .

Snorkeling is a marine leisure activity that enjoys underwater sightseeing on the water with simple equipment. Snorkeling requires fin, snorkel, snorkel, mask, diving gloves, wetsuit, lead weight belt, inflatable vest for resting on the water, underwater knife, etc. .

2. Description of the Related Art In general, snorkel equipment has been developed and used so far. Various snorkel equipment have been developed and used. The snorkel includes a mouthpiece for holding the snorkel by the user's mouth in the water surface, a mouthpiece connected at one end to the mouthpiece, It is made of a hollow hose so that the wearer can breathe air. In other words, snorkeling is a structure that breathe through the snorkel connected to the surface of the water, and can be closed with one breath.

Another marine leisure sport similar to snorkeling is Scuba Diving, a marine leisure sport with scuba equipment that dives to a depth of about 30 meters. Specifically, it refers to an independent type of underwater breathing apparatus. In other words, a scuba is a device that can breathe in the water without being directly supplied with air. The equipment is equipped with an air reservoir that stores compressed air at high pressure, an aqua regulator, a buoy regulator, an air pressure gauge, a water depth gauge, a compass, an emergency respirator, and an underwater computer.

Conventional snorkeling, however, is limited to enjoying in the deep water, enjoying at sea level or breathing in one breath, and conventional scuba diving is expensive due to heavy equipment, which is complicated and time consuming to wear. There was also a burden on the cost. Also, the impossibility of agile activities in the water was felt to be a considerable inconvenience.

In addition, there is an advantage that the beauty of the full face mask 1 can be improved.

A support base 310 is installed at one end of the housing 30. A protruding member 300 is formed at the center of the support 310 so that the center axis of the protruding member 300 is aligned with the central axis of the needle body 430 of the valve device 4 The protruding member 300 automatically presses the needle body 430 to be described later so that the compressed air in the cylinder 3 is discharged to the inside of the full face mask 1 .

The cylinder (3) is coupled to the housing (30) and installed integrally. The cylinder 3 may be a single cylinder or a double cylinder. The cylinder 3 is provided with a cylinder body 31 having an inlet 32 through which compressed air flows in or out and a valve body 32 provided at the inlet 32 for controlling opening and closing of the inflow or outflow of compressed air, (4).

Compressed air or oxygen is stored in the cylinder body 31, and a thread is formed on the inner surface of the entrance 32. A valve device 4 to be described later is installed inside the cylinder body 31, is bolted to the frame 2, and inserted into the housing 30 to be double-coupled. An O-ring 33 is provided at the lower end of the entry / exit port 32 to prevent a strong coupling with the valve device 4 and a leakage of compressed air in the cylinder 3, which will be described later.

The valve device 4 includes a body 41, a cap part 42 and a needle part 43. The valve device 4 is mounted on the cylinder body 31 and is movable up and down.

A space 410 is formed on the inner side of the body 41. The space 410 is provided with a needle portion 43 to be described later, and a screw thread is formed on the outside of the space 410 to be installed at the entrance 32 of the cylinder body 31. A groove 411 is formed inwardly from the upper end of the body 41. The groove portion 411 has a depth enough to press the needle portion 43 to be described later.

The cap part 42 is installed on the lower side of the body 41 and closes the lower part of the space 410. The cap portion 42 is mounted on the lower side of the body 41 in a bolt-assembled manner. At this time, the lower end of the cap part 42 and the lower end of the cylinder body 31 are positioned on the same line. In addition, a hole is formed in the center of the cap portion 42, and a needle portion 43 to be described later penetrates. An air hole 420 is further formed in the cap portion 42. The air holes 420 serve to move the compressed air in the cylinder body 31 into the space 410 or allow the compressed air in the space 410 to move to the cylinder body 31.

The needle portion 43 is installed inside the body 41, more precisely, in the space 410. The needle portion 43 includes a cylindrical needle body 430 and a protrusion 431 integrally formed with the needle body 430 to limit the upward and downward movement range of the needle portion 43. The upper end of the needle body 430 is installed to penetrate the upper end of the body 41. The lower end of the needle body 430 is installed through a hole formed at the center of the cap portion 42, ) To move up and down.

It is preferable that the position of the upper end of the protrusion 431 is located on the same line as the upper end of the space 410 and the position of the lower end of the protrusion 431 is located higher than the lower end of the space 410. Thus, the vertical movement range of the needle body 430 in the space 410 is restricted. When the needle body 430 is installed in the housing 30 and connected to a bolt provided on the frame 2, the needle body 430 is automatically pushed so that the compressed air in the cylinder 3 flows into the inside of the full face mask 1 .

An elastic member 6 is provided between the protrusion 431 and the cap portion 42. The elastic member 6 is generally a spring and the elastic member elastically applies force to the needle portion 43 to close the upper end of the space 410 when the user does not press the needle portion 43 Respectively. An O-ring 5 is provided between the protrusion 431 and the inner upper end of the space 410 to seal the space 410.

The valve device 4 is provided to reduce the pressure of the air flowing out of the cylinder 3 and to be automatically opened and closed when it is separated by connecting bolts. Further, since there is no protruding portion to the outside of the cylinder 3, the structure is simple, the cost can be saved, and the safety can be improved. The valve device 4 and the cylinder body 31 are coupled by screwing There is an advantage that repair or replacement can be facilitated in case of failure or deterioration of performance.

This full face mask 1 allows the valve device 4 to be opened when the cylinder 3 and the housing 30 are coupled so that the compressed air is transferred into the full face mask 1 and the cylinder 3 and the housing 30 30, the valve device 4 is closed to form an automatic opening / closing valve device.
