Abstract
The utility model proposes a kind of whistle with retaining valve, the whistle body comprising blow gun and be connected with blow gun, blow gun connects retaining valve, and retaining valve is connected with whistle body.A kind of whistle with retaining valve of the utility model, at blow gun, place arranges retaining valve, extraneous dense smoke can be stoped to enter, use safety.
Description
Technical field
The utility model relates to a kind of whistle, particularly relates to a kind of whistle with retaining valve.
Background technology
The general whistle, present whistle body is communicated with blow gun, can to going out to blow, extraneous gas equally also can enter whistle body, sucked by people, generally the whistle of this structure does not have any problem, but has some special circumstances, under such as dense smoke state, in order to ensure the safety of the person, use during whistle and dense smoke just can not be allowed to be inhaled into, existing whistle obviously cannot meet use in this case.
Utility model content
In order to solve technical matters existing in background technology, the utility model proposes a kind of whistle with retaining valve, at blow gun, place arranges retaining valve, extraneous dense smoke can be stoped to enter, use safety.
Technical solution of the present utility model is: a kind of whistle with retaining valve, and the whistle body comprising blow gun and be connected with blow gun, is characterized in that: described blow gun connects retaining valve, and retaining valve is connected with whistle body.
Above-mentioned whistle body is pneumatic sounding body.
Above-mentioned retaining valve is cooling gas check valve.
Above-mentioned retaining valve is ball point type retaining valve or diaphragm type one-way valve.
Above-mentioned retaining valve is ball point type retaining valve, and the diameter of retaining valve grid film perforation is less than the diameter of ball in ball point type retaining valve.
In above-mentioned retaining valve, ball is plastics or metal ball.
Retaining valve is connected with blow gun, whistle body for overall or flexible connection.
Retaining valve and blow gun, whistle body link are that flexible material is made.
Blow gun and the whistle body material be connected with blow gun are plastics, wood, metal material are made.
The whistle of band retaining valve of the present utility model, at blow gun, place arranges retaining valve, and outside air can be stoped to enter, and under going for the environment of dense smoke, raises the efficiency when lifesaving; In addition, on rear side of retaining valve, be provided with grid, non-return valve operational is more stable, also can play certain iris action, and structure is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the second example structure schematic diagram of the present utility model;
Fig. 3 is mesh flake structural representation in the utility model;
Embodiment
See Fig. 1, the utility model proposes a kind of whistle with retaining valve, the whistle body 2 comprising blow gun 1 and be connected with blow gun 1, whistle body 2 is pneumatic sounding body, and retaining valve 3 is cooling gas check valves, mainly adopts ball point type retaining valve or diaphragm type one-way valve; Blow gun 1 place connects ball point type retaining valve 3, and arrange mesh flake 4 on rear side of retaining valve 3, be provided with ball 6 before mesh flake, mesh flake 4 is fixedly connected with whistle body 2 inwall.Retaining valve 3 is connected for overall or flexible connection with blow gun 1, whistle body 2;
See Fig. 2, the whistle body 2 comprising blow gun 1 and be connected with blow gun 1, blow gun 1 place connects diaphragm type one-way valve 3, and arrange mesh flake 4 on rear side of retaining valve 3, be provided with diaphragm 7 before mesh flake, mesh flake 4 is fixedly connected with whistle body 2 inwall; Mesh flake 4 is arranged the hole 5 of multiple random alignment, see Fig. 3; When employing ball point type retaining valve, the diameter in hole 5 is less than the diameter of plastic bead 6 in ball point type retaining valve, also can adopt here metal ball or other; Blow gun 1 and the whistle body material be connected with blow gun 1 are that the materials such as plastics, wood, metal are made; The utility model arranges retaining valve 2 at blow gun 1 place, outside air can be stoped to enter, go for the use under the environment of dense smoke.The utility model proposes a kind of whistle, go for aluminium alloy whistle, whistle is sought survival in open air, the two-tube whistle of high frequency, judge whistle, metal whistle, stainless steel whistle campaign whistle etc., the whistle is high-decibel, height, intermediate frequency sound.
