Abstract

The utility model discloses a multifunctional self-defense alarming ejector, and belongs to the field of self-defense equipment. The multifunctional self-defense alarming ejector aims to solve the problems that the conventional 'lady-killer sprayer' can spray but cannot give an alarm, or the 'lady-killer sprayer' can give an alarm but cannot spray, and a self-defense effect cannot be achieved because of the limited range of the sprayer and limited spraying scope. The alarming ejector comprises a battery, a sound-generating circuit board, a switch, a safety catch, an ejector body, a soft capsular bag and the like. The alarming ejector is characterized in that a 120 decibel alarm is given when the safety catch is pulled out, simultaneously an ejector pipe is opened, and self-defense liquid is sprayed while the alarm is given, so that a user can frighten a bad guy and stop the injurious act of the bad guy. Compared with the prior art, the multifunctional self-defense alarming ejector has the advantages that 1, the self-defense liquid can be sprayed after the safety catch is pulled out to sound an alarm, and the multifunctional self-defense alarming ejector can be prevented from being despitefully used; 2, the safety catch with an internal concave design is matched with the ejector pipe, so that the liquid is prevented from leaking; 3, the capsular bag is made of a soft material, and automatically retracts after the ejector liquid is used up, and pressure difference is offset; 4, the filling liquid is cheap and efficient wind medicated oil; and 5, an efficient sound amplifying circuit is employed, so that the sound of an alarm is loud and clear.

Description

A kind of Multi-functional self-defense warning injector

Technical field

The utility model relates to a kind of multi-functional, alarming injector, belongs to self-defence equipment field.

Background technology

At present; the malignant event such as have many avoidable robberies, violence in the society, rape, but because people's sense of self-protection is thin, in addition very effective easily self-defence utensil not; the incidence of this type of event is always high, allows a lot of not guilty weak persons experience all kinds of misery.

Certainly, the product that occurs on the market now-" anti-wolf sprayer " only utilizes the vaporific excitant liquid of ejection, and this class I liquid I has and much all is poisonous or arrives human body, such as eyes, fatefulue injury is caused to the people in the capital, reaching the purpose that stops the ruffian to attack, but these injuries also are inequitable concerning the ruffian by such approach.Next is exactly that they do not reach the perfect of the unification of function and function: on the one hand, and the emergency sound that but can not reporting to the police of can spraying sent " I want help ", but can not spraying of can reporting to the police; On the other hand, the range of sprayer and the scope of penetrating are also very little, are difficult to reach the effect of defence self.Moreover a lot of exactly utensils are because himself structure and attribute cause the user to be unsuitable for it is gone out to carry, and have intensity low, the shortcomings such as price height, thereby popularity rate is low, and market is narrow, and it is low that the consumer holds rate.

For this kind product is better optimized and innovation and application in the middle of people's daily life, the utility model discloses a kind of Multi-functional self-defense warning injector that integrates injection, warning sounding, throws light on.

Summary of the invention

Inconvenience and irrationality when using in actual life for existing anti-wolf sprayer, simultaneously for this product is reasonably optimized and innovation, and do not cause the supernumerary to give birth to injury, to satisfy the needs of vast disadvantaged group, the utility model discloses a kind of self-defense alarming injector that gathers multi-function in integral whole.

Realize the Multi-functional self-defense warning injector of above-mentioned utility model technical scheme, be made of injection apparatus, warning sound-producing device [4], lighting device three parts, it is characterized in that: described warning sound-producing device [4] is made of battery case [3], chip and loudspeaker [4], wire [5], contact chip [7], cap ned [8], lock [9] and backguy [13]; Described warning sound-producing device [4] cut-offs by the lock that is inserted in cap ned [8] [9] to be controlled; Described lock [9] is for there to be evagination that the vulcanie cylinder of snap ring is arranged; Described two contact chips [7] sound-producing devices taking alarm [4] are fixed on the cap ned [8] that can take out by primary screw after cut-offfing line; Described lock [9] inserts cap ned [8] warning sound-producing device [4] and disconnects, and lock is extracted cap ned [8] warning sound-producing device [4] closure, and chimes of doom sounds; Described lighting device is made of switch [1], illuminating lamp [2], battery case [3]; Described injection apparatus is made of conduit [6], lock [9], main body [10], control button [11] and liquid capsule [12]; Described liquid capsule [12] is that soft anticorrosive rubber consists of, and is used for the liquid that splendid attire sprays, and can shrink and offset the pressure difference that causes because of injection; Described outer mounted box is that 78mm * good plastics of 55mm light enclosed are made; The sound that described warning sound-producing device [4] sends is " I want help " sound of 120 decibels.

Described spray gun [10], its range are about 5 meters, and institute's atomizing of liquids is essential wind oil; The utricule [12] that stores liquid adopts soft rubber to make, and automatically shrinks behind the atomizing of liquids and offsets the pressure difference that produces because of discharging liquid; [9] fitted seal is fastened in injection catheter [6] nozzle and insurance, has prevented from evaporating, and also indirectly plays the control alarm switch.

Described alarm [4] refers to the contact piece type alarm, pulls up insurance and fastens [9], and switch closure begins to report to the police, and the sound of warning can change by the chip recording program, and alarm sound is 120 decibels " I want help " or " sound of 110 police cars ".

Described cap ned [8] mainly is the effect of control alarm switch, fastens [9] when plugging when insurance, backs down contact chip [7] contact point, switch is disconnected, when pulling up lock [9], contact chip [7] closure, begin to report to the police, do not fasten [9] if do not turn back to insurance, will continue to report to the police.

[9] are fastened in described insurance, done by the hard, wear-resistant elastomeric material, and its shape indent ring-type, mainly play the function of two aspects: one prevents that liquid from omitting or evaporate; Its two, control cap ned [8] switch namely plays indirectly control and reports to the police.

Compare with existing product, the disclosed Multi-functional self-defense warning of the utility model injector has following advantage:

(1) the playpipe leading portion goes out bore and slowly dwindles, and is beneficial to the speed that increases atomizing of liquids; Liquid adopts without mortality but strong and stimulating liquid, such as essential wind oil, reaches the purpose of preventing the bad person under the prerequisite that does not cause necessary personal injury.

(2) the warning sound-producing device sends the emergency sound of " I want help ", has increased its practicality, is convenient to attract passerby to help.

(3) lighting device is available for users to the temporary lighting in evening, and whole device is light small and exquisite, is easy to carry.

(4) when liquid, remove lid with simple tool when battery uses, loading and unloading battery, and take out the liquid capsule carrying liquid, reach the nonexpondable effect of circulation.

(5) the liquid jet length is far answered 5m, at a distance ego defense.

(6) after lock [9] was extracted, warning continued, and alarm can be flung at the individual who is encroached on, and had reached to help others out of danger in the situation about not sticking one's chin out.

(7) push lock [9] alarm sound time-out aside and can spray self-defence liquid, prevented that injector from being utilized attack passerby by the bad person.
