As shown in figure 3, air flue 11 includes the first passage portion that is vertically arranged and opens up in the horizontal direction and with the
The second channel portion of one channel part connection;Needle entrance 113 is hit in setting above first passage portion, and lower section is air flue air inlet 111,
Connect the air source gas outlet;The outlet of second channel portion is air flue gas outlet 112, connects the compressing gasbag 3.Described first is logical
Needle displacement channel is hit in the top setting in road portion, and the shock needle displacement channel is connected to first passage portion and axis overlaps.
Fig. 4 is the assembled state sectional view before the triggering of the chance water self-filler of the embodiment of the present invention one.
As shown in figure 4, first screwing in air source 2 in the air flue air inlet 111 of valve body 1, the tracheae of compressing gasbag 3 will be connected
In the air flue gas outlet 112 of 31 access valve bodies 1.
Hitting needle 51 can be by hitting needle entrance 113 into air entering flue 11, and will hit needle by water-soluble locating part 53
51 are limited in shock needle entrance 113.
Water-soluble locating part 53 is annular, and water-soluble locating part 53, which is sheathed on, to be hit on needle 51, and the shock needle 51 passes through
Water-soluble locating part 53, which is supported in, hits 113 outer rim of needle entrance.
Plug screw 54, shape and 113 shape of shock needle entrance of plug screw 54 are provided between boss 513 and water-soluble locating part 53
Shape is adapted, and after shock needle 51 punctures sealer 21, plug screw 54, which is supported in, hits 113 outer rim of needle entrance, and will hit needle entrance 113
Sealing.
As shown in figure 3, it can be overall structure to hit needle 51, or separate structure, the shock needle in the present embodiment
51 be separate structure, is made of push rod 512 and arcing piece 511.Water-soluble locating part 53 is set on arcing piece 511, plug screw 54
It is fixedly connected on 511 top of arcing piece.
In the present embodiment, 511 top of arcing piece has helicitic texture, plug screw 54 and 511 screw top phase interworking of arcing piece
Conjunction is spun together.
After water-soluble locating part 53 is set in from 511 top of arcing piece on arcing piece 511, plug screw 54 is fixedly connected on
511 top of arcing piece assembles arcing piece 511 and water-soluble locating part 53 and plug screw 54.By assembled arcing piece 511
It is placed in the shock needle entrance 113 of valve body 1 with water-soluble locating part 53 and plug screw 54, enters the first passage portion of air flue 11
In.The outer dia of water-soluble locating part 53 is more than the outer rim for hitting needle entrance 113, since the blocking of water-soluble locating part 53 is made
Needle entrance 113 is hit with 53 bottom of water-soluble locating part to be resisted against, plug screw 54 is pressed together on the top of water-soluble locating part 53, such as
Shown in Fig. 4.
Plug screw 54 is that upper end diameter is more than 113 outer rim of shock needle entrance in first passage portion, lower end diameter is less than first and leads to
The T-type structure of road portion inside dimension.
The centre bore 42 that the push rod 512 for hitting needle 51 is passed through to shell 4, passes through being threaded on valve body 1 on shell 4
In screw thread, after shell 4 is fully screwed into, at this point, boss 513 is resisted against on plug screw 54, the top of push rod 512 is from sleeve 4
The top in heart hole 42 is pierced by, and the compression of pretension elastic component 52 is made to generate pretightning force.The decrement of pretension elastic component 52 generates pre-
Clamp force can make push rod 512 push plug screw 54, to make arcing piece 511 puncture the envelope of air source 2 when discharging pretension elastic component 52
Film 21.
Fig. 5 is the assembled state sectional view after the triggering of the chance water self-filler of the embodiment of the present invention one.
As shown in figure 5, meeting water self-filler 100 after meeting water, flow is flowed by the infiltration through-hole 41 on shell 4
Into shell 4, dissolved rapidly after water-soluble locating part 53 encounters flow, in the barrier effect for losing water-soluble locating part 53
Afterwards, push rod 512 pushes plug screw 54 and arcing piece 511 to inside the first passage portion of air flue 11 under the action of pretension elastic component 52
Movement.
After water-soluble locating part 53 meets water dissolution, push rod 512 pushes plug screw 54, makes the of 54 lower end of plug screw push-in air flue 11
In one channel part, 54 upper end of plug screw, which is pressed together on, hits on needle entrance 113, first passage portion is sealed, arcing piece 511 is in plug screw 54
Drive under breakdown air source 2 sealer 21 after, first passage portion through air flue 11 of gas in air source 2 and second channel portion are from gas
Road gas outlet 112 flows into tracheae 31, to be inflated to compressing gasbag 3.
In the present embodiment, hits and be also provided with axial groove and/or circumferential groove on the arcing piece 511 of needle 51, be conducive to fill
The quickening of flow rate of gas when gas.
There is wedge angle on the head of arcing piece 511.Wedge angle can be one or more, with the shape when piercing through the sealer 21 of air source 2
At the tearing port of bigger so that the gas in air source 2 can be quickly charged in compressing gasbag 3.
In the present embodiment, generally " ten " font structure of arcing piece 511 is equipped with convex in the medium position of arcing piece 511
Edge, for accepting water-soluble locating part 53, to prevent water dissolubility locating part 53 from undesirably falling off.
In the present embodiment, 53 surface of water-soluble locating part opens up cutting, accumulates, improves with water engaging surface to be conducive to increase
The rate of dissolution of water-soluble locating part 53.Water-soluble locating part 53 is made of water-soluble high-molecular material, such as water solubility PVC
Deng.Water-soluble locating part 53 has certain intensity, and water-soluble locating part 53 will not be damaged in normal state, hits needle 51 not
Understanding external trigger makes compressing gasbag 3 inflate.
In the present embodiment, the material of compressing gasbag 3 is made using the tough ageing-resistant thin-film material of lightweight.Meeting water
When compressing gasbag 3 expansion and gassy generate buoyancy time be 2 seconds to 5 seconds in.
Air source 2 is dry ice gas cylinder, and suitable dry ice lumps are housed in bottle.After meeting 100 use of water self-filler, pass through
Water-soluble locating part 53 and air source 2 are replaced, may be reused.
