Abstract

The utility model relates to a pen-shaped whistle alarm provided with a pen-shaped plastic casing whose head is provided with a compressing switching key, one side of the neck of the casing is provided with an air outlet and a pen holder, and the bottom is provided with a turnable bottom cap connected with the bottom via screws. The utility model is characterized in that the casing inside is provided with a metal cylinder in which high-pressure liquid gas is filled; the neck of the cylinder is provided with an air out device whose extending pipe top is provided with a whistle generator close up to the bottom of the compressing switching key. Once the compressing switching key is pressed, jarring sharp whistle can be generated to give an alarm. The pen-shaped whistle alarm with convenient carrying can be plugged in a pocket with novel and unique properties, can be used in all weather without energy and is a protecting emergency alarm safety tool for all people.

Description

Penlike whistle-sound alarm

The utility model belongs to the urgent whistle warning of personal safety utensil.

Past is when weak person is prominent when attacked by the ruffian, owing to have no to prepare, do not have the utensil that can report to the police, causes the ruffian to torture wantonly; Old have heart disease, a hyperpietic, and stroke sometimes in critical condition, but because the unmanned or utensil of self not reporting to the police in the family, delays the diagnosis and treatment the time and loses the chance of rescuing life.If the whistle of preparation warning utensil is arranged, then can in time press aloud, it is very high to send a kind of audio frequency, and has the whistle of screaming of deterrence sound effect, just can play the warning effect, makes from must people far away hearing distress call, and danger is rescued at the scene of arriving in the very nick of time.

The purpose of this utility model provides a kind of pen type whistle alarm, and is easy to carry, uses simple and flexible, plays self-defence emergency alarm effect.

The utility model is finished as follows: at head the compression switch key is arranged, neck one side has the gas outlet with corresponding position pen clip to be arranged, the bottom has can revolve in the pen type plastic casing that bottom is threaded with it metal cylinder is installed, high-pressure liquid gas is housed in this tube, and the neck of tube is equipped with air-out apparatus; Its protruded tube upper end is equipped with the whistle generator above this device, and protruded tube puts in the corresponding hole of whistle generator, and the whistle generator is close to compression switch key bottom.Press and promote the whistle generator shell when the compression switch key, promote protruded tube simultaneously, make air-out apparatus work emit high pressure draught, send sharp strict whistle, spread out of from the gas outlet by the vibrating membrane in the whistle generator.

The utility model has following advantage than conventional art: 1, easy to carry, can insert pocket, the using method simple and flexible.2, when pressing the compression switch key, can send the strict whistle of thorn have sharp ears, play the warning effect.3, need not the energy, can round-the-clockly use.

Further describe below in conjunction with accompanying drawing.

Fig. 1 is the external form figure of pen type whistle alarm.

Fig. 2 is the structural drawing of pen type whistle alarm.

With reference to Fig. 1, the whistle alarm has a pen type plastic casing (8), and head has compression switch key (1), and neck one side has gas outlet (7), there is pen clip (10) at position corresponding with it, and the bottom of housing (8) has can revolve bottom (9) and be threaded with housing (8).

With reference to Fig. 2, metal cylinder (4) is installed in the housing (8), the employing alloy aluminum is made, in the tube (4) high-pressure liquid gas (6) is housed, the tube neck is equipped with air-out apparatus (5), this installs valve just, presses the protruded tube of air-out apparatus (5), promptly opens air valve the high-pressure liquid gas (6) in the aluminum barrel is sprayed.The protruded tube upper end of air-out apparatus (5) is equipped with whistle generator (2), and protruded tube puts in the corresponding hole of whistle generator (2).The whistle generator has a horn opening in (2), forms a narrow slit between its bottom and the vibrating membrane (3), and vibrating membrane (3) is installed in tubular air chamber one side, and tubular air chamber and whistle generator (2) housing seal are fastenedly connected.

Promptly promote whistle generator (2) shell when pressing compression switch key (1), simultaneously also promote protruded tube, make air-out apparatus (5) open valve, thereby emit high pressure draught, send the strict whistle of thorn have sharp ears by the vibrating membrane (3) in the whistle generator (2), from gas outlet (7), spread out of.Said vibrating membrane (3) is the electric metal vibrating membrane.High-pressure liquid gas (6) is fluorine Lyons.The structure of air-out apparatus (5) is known, as air pressure pesticide bottle etc.When thumb was decontroled compression switch key (1), the little spring in the air-out apparatus (5) resetted and closes and give vent to anger.

The utility model need not power supply and other energy are used as power, so can round-the-clockly use.Simultaneously nontoxic, the odorless of the liquid gas in the aluminum barrel, do not fire, not quick-fried safe and reliable.
