High-pressure liquid injection protection umbrella

Abstract

The invention relates to a police security device and provides a high-pressure liquid injection protection umbrella having a protection function. The high-pressure liquid injection protection umbrella having the protection function comprises a piston (1), an umbrella handle main body (2), a spraying opening (3), a liquid storage chamber (4), a one-way valve (5), an umbrella cover (6) and an umbrella rib (7) and is characterized in that the piston (1) is arranged at the lower end of the umbrella handle main body (2); the spraying opening (3) is formed in the top end of the umbrella handle main body (2); the liquid storage chamber (4) is arranged on one side of the umbrella handle main body (2); the one-way valve (5) is arranged between the liquid storage chamber (4) and the umbrella main body (2). According to the high-pressure liquid injection protection umbrella having the protection function, a police umbrella is combined with a high-pressure injector, the structure is simple, the utilization is safe and convenient, and problems that the existing police umbrella is single in function and lack of a counterterrorism and antiriot function are solved.

Description

technical field [0001] The invention relates to a high-pressure liquid jet protective umbrella with protection function. Background technique [0002] The existing police umbrella product has a single function and lacks the anti-riot function problem. [0003] Existing anti-riot jet self-defense devices used by the police are not safe enough to use. When using the jet, some of the irritating objects sprayed will be sprayed on the user himself due to the short spray distance, or the mob will use clothing to cover the sprayed objects. The irritating object is blown towards the user himself. [0004] The existing anti-riot spray self-defense device has the problems of small injector volume, less propellant filling amount and shorter spraying distance. Its reason is: existing anti-riot jetting self-defense device is launch power with propellant, and the main effect of propellant is to form a pressure in injector tank body, and stimulating agent can be ejected by valve; As inj...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention uses the umbrella surface as a protective shield, uses the umbrella handle as the main body of the injector, and uses the manual push of the piston or the electric piston to generate high-pressure gas as the power, providing a high-pressure liquid injection with a protective function The protective umbrella solves the problem that the existing police anti-riot spray self-defense devices are not safe enough to use and the existing police umbrella products have a single function and lack anti-riot functions.
