Detailed description of the invention

Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described further.

Refer to Fig. 1 and Fig. 2, a kind of submarine breathing tube of the utility model preferred embodiment design, comprising: body 40 and the tube head 10 being located at body 40 upper end; To be located on tube head 10 madial wall and to offer the cavity 12 of discharge port 11; Be placed in the circular ball float 20 in cavity 12; Be sheathed on the seal ring 30 of air inlet/outlet 31 above cavity 12; When ball float 20 floats and seal ring 30 act on air inlet/outlet 31 sealed.Wherein, ball float 20 can arrange one, also can arrange multiple, and in the present embodiment, ball float 20 preferably arranges two, and is provided with the magnet attracted each other in two ball floats 20.

When tube head 10 stretches out the water surface, ball float 20 gravitate, can sink to the bottom of cavity 12, and now, the air in body 40 exchanges with outside air through air inlet/outlet 31 and discharge port 11.

When have wave beat or tube head 10 sinks under the water time, having water flow in cavity 12 from discharge port 11, when the water in cavity 12 is filled out to certain altitude, ball float 20 can rise because of buoyancy of water, thus work on air inlet/outlet 31 seal plug with seal ring 30 1, now water just cannot enter in body 40 from air inlet/outlet 31.Ball float 20 is for existing hinged anti-water piston, because of few with the contact internal walls area of cavity 12, add upper floating ball 20 spherome surface smooth, even if there are the inclusion particles such as sand to enter in cavity 12, also be not easy to block ball float 20, thus the up-and-down movement of ball float 20 can not be had influence on.Meanwhile, because two ball floats 20 can attract each other together, when water enters in cavity 12, the ball float 20 of below can first float, and drives ball float 20 upward movement together of top, thus is blocked rapidly by air inlet/outlet 31, reduces body 10 as far as possible and intakes.

Tube head 10 is made up of cylindrical shell and lid, and the edge of lid is provided with four buckles, and buckle correspondence fixes in cylindrical shell upper end, and is provided with O-ring seal in lid and the junction of cylindrical shell and the junction of cylindrical shell and body 40.

Body 40 is divided into three-stage structure, is respectively the suction pipe 41, the threaded line pipe 42 with the be difficult to articulate 50 pipe tails 43 be connected and connected sucking pipe 41 and pipe tail 43 that are connected with tube head 10.Be difficult to articulate 50, body 40 and tube head 10 inside mutually through, flow for air.

Refer to Fig. 3, threaded line pipe 42 comprises some large-diameter portions 422 and some minor diameter parts 421, every two large-diameter portion 422 midfeather minor diameter part 421.Threaded line pipe 42 preferably adopts silica gel material.When threaded line pipe 42 is by bending, close to each other and even offset by extruding minor diameter part 421 by the adjacent large-diameter portion in side 422 that compresses, even if but bending dynamics is large again, mutually abut because there being multiple large-diameter portion 422 and produce antagonistic force, so situation about cannot can not ventilate in bending to body 10, prevent diver from suffocating.And traditional breathing pipe body is after bending to a certain extent, air by-pass passage may be blocked, easy asphyxiant danger.

The inner bottom part of pipe tail 43 is formed with water storage cavity 431, for storing the small part water entered from air inlet/outlet 31, to be difficult to articulate 50 sides being located at pipe tail 43, and be difficult to articulate 50 height higher than the height of water storage cavity 431, therefore, even if there have a small amount of water to enter into body 10 to be inner, also 50 diver can not be entered in the mouth by being difficult to articulate.The one-way check valve block 60 for draining is also provided with in the lower end of water storage cavity 431.When water storage cavity 431 stores part water, 50 firmly feel elated and exultant by being difficult to articulate and impact one-way check valve block 60, backed down, thus discharge the water of water storage cavity 431.When normal ventilation, because impulsive force is more weak, one-way check valve block 60 can not arbitrarily be backed down; simultaneously also because of the effect of external water pressure; one-way check valve block 60 and pipe tail 43 are fitted tightly, and therefore, it is inner that extraneous water can not enter into body 40 from one-way check valve block 60.

Refer to Fig. 4, be difficult to articulate 50 by be difficult to articulate on integrated 51 and under be difficult to articulate and 52 form, be above difficult to articulate 51 both sides corresponding with under be difficult to articulate 52 both sides be connected, under be difficult to articulate in 52 and offer the breathing port be connected with pipe tail 43.50 uses of being difficult to articulate of Integral design are more laborsaving, convenient.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
