Description

Diving respiring tube

The utility model relates to a kind of schnorkel, especially refer to the be difficult to articulate schnorkel of angle of a kind of lower, planar air admission type multi-directionally adjustment, it can make, and the scuba diver exempts drinking water, the danger of the water of choking, and can adjust the angle of being difficult to articulate arbitrarily and make it to be in comfortable natural running condition.

Breathing pipe is called as the diving Triratna with frog mirror, frog footwear, is the important equipment of diving activity, and especially at the indispensable especially equipment of the activity of snorkeling (claiming snorkel diving again), its effect is to help the scuba diver when the water surface snorkels, and looks for and sees the still sustainable breathing of scenery in the water.

The breathing pipe of commonly using at present, the modal circular hollow tube that is configured to the about 1.5cm～2cm of a diameter, the about 30cm～40cm of length; This pipe top is the open mouth of pipe, and as the usefulness of air ports, the pipe bottom connects one and is fit to the soft of mouth type and is difficult to articulate, and a sheathed clip on pipe then is fixed on the frog mirror in order to breathing pipe in addition.During use, clip is clamped on the headband of frog mirror; Therefore when user (scuba diver) wore frog mirror, breathing pipe just also was fixed in scuba diver's head with frog mirror together, that is, frog mirror covers user's face, and breathing pipe then is positioned at user's head side approximately near ear location.When snorkeling activity, the user just can pick up soft being difficult to articulate that is arranged in the pipe bottom and nibble mouth, face snorkels down in water, and make the pipe upper end protrude in the about 15cm of the water surface, because the pipe upper end is the open mouth of pipe, keep the unimpeded of user's mouth and outside air, on one side so the user just can watch water-bed scenery, Yi Bian continue to keep breathing via breathing pipe with the mouth ventilation.

Though above-mentioned breathing pipe can allow the user take a breath in water, yet this breathing pipe top mouth of pipe is adopted complete open by design, in the middle of snorkeling, pat near the water surface or because of the covering or the impact of the wave or the spray if user's head fails to keep certain correct angle to cause breathing pipe to tilt to its mouth of pipe, its seawater all very easily enters in the pipe from the mouth of pipe of breathing pipe.When the user feels when having in the water intrusion pipe, just must hold one's breath earlier (sealing), water just can not swallowed (drinking water) in the tripe, utilize then the strength of belly firmly will manage in ponding blow out (blowing water), in order to respiratory ventilation next time, this is the blowpipe technology that needs very much craftsmenship.Yet because the instability of wave and user's head fail to be maintained fixed at any time angle, therefore, seawater all has possibility in the dipleg at any time, thus the user just need blow water constantly.This is for a beginner, need be quite careful, if careless slightly, promptly can cause the danger of drinking water, the water of choking easily, although be a skilled worker, though it is experienced, blow water skill maturation, sometimes also unavoidably carelessness cause drinking water, the water phenomenon of choking, and when snorkeling, blow water for a long time muscle power quite expended, moreover, be full of seawater frequently in mouthful, its flavour is not also felt better.These cause drinking water easily, the dangerous phenomenon of the water of choking, and are to commonly use the topmost shortcoming of breathing pipe place.

Though have at present at the above-mentioned breathing pipe phenomenon of unawareness water inlet easily of commonly using, various so-called automatic water stopping breathing pipes are provided, its complex structure also makes the user that the fear sense of inhaling for the moment less than air is arranged sometimes.

Again, breathing pipe is still not ideal enough when wearing use at present, causes the very big uncomfortable part of user, and that occurs in the part of being difficult to articulate exactly.Present breathing pipe, its angle of being difficult to articulate is generally fixing or is fixed shaft type, only but former and later two directions are adjusted, yet, wearing of breathing pipe is to be fixed in user's head outside near the ear part, when the user will be difficult to articulate when placing mouth, will excuse portion angle differs between the outside and oral area relation, making is difficult to articulate produces one and turns round phenomenon partially between part and the pipe, still, this pipe is to be fixed on the headband of frog mirror, thereby this turns round phenomenon abiogenesis partially in the part of being difficult to articulate, and makes the part of being difficult to articulate have to take off from user's mouth at any time and turns round positive trend and strength at home and abroad, at this moment, the user can only firmly bite with mouth and be difficult to articulate, in case this is difficult to articulate in the removal outlet.Though some is difficult to articulate present breathing pipe and can rotates to eliminate some angles front and back, but because each user's shape of face differs, this angle of being difficult to articulate only is the fore-and-aft direction adjustment, still can't adjust the angle of being difficult to articulate of ideal nature according to everyone, is still very uncomfortable when therefore wearing.Moreover the active length when at every turn snorkeling generally was about about 1～2 hour, for a long time down will be all the time bites with oral area strength in this that to be difficult to articulate be like a hen on a hot girdle and easy fatigue.This is the present breathing pipe obvious shortcoming that part caused in being difficult to articulate.

The purpose of this utility model is to provide a kind of lower, planar air admission type multi-directionally adjustment schnorkel of angle of being difficult to articulate, and can avoid breathing pipe water inlet and can be according to the individual demand adjustment use angle of angle to the most comfortable nature of being difficult to articulate.

The purpose of this utility model reaches as follows:
