Embodiment 1

[0017] Example 1: like figure 1 As shown, a protective umbrella for high-pressure powder spraying with protective functions includes a piston 1, an umbrella handle body 2, an ejection port 3, a powder storage room 4, a one-way valve 5, an umbrella surface 6, and an umbrella rib 7. Its characteristics Yes: the piston 1 is located at the lower end of the umbrella handle main body 2; the ejection port 3 is located at the top of the umbrella handle main body 2; the powder storage chamber 4 is located on one side of the umbrella handle main body 2 and contains irritating powder. There is a one-way valve 5 between the powder storage chamber 4 and the umbrella handle main body 2 .

Embodiment 2

[0018] Example 2: like figure 1 As shown, a protective umbrella for high-pressure powder spraying with protective functions includes a piston 1, an umbrella handle body 2, an ejection port 3, a powder storage room 4, a one-way valve 5, an umbrella surface 6, and an umbrella rib 7. Yes: the piston 1 is located at the lower end of the umbrella handle main body 2; the ejection port 3 is located at the top of the umbrella handle main body 2; the powder storage chamber 4 is located on one side of the umbrella handle main body 2 and contains irritating powder. There is a one-way valve 5 between the powder storage chamber 4 and the umbrella handle main body 2; the piston 1 is equipped with an electric drive device and a power supply, and when the electric drive device is started, the piston 1 can move back and forth quickly in a straight line, so that the gas in the umbrella handle main body 2 is formed. high pressure gas.

Embodiment 3

[0019] Example 3: like figure 1 As shown, a protective umbrella for high-pressure powder spraying with protection function, including piston 1, umbrella handle main body 2, spray outlet 3, powder storage room 4, one-way valve 5, umbrella surface 6, umbrella rib 7, air pressure valve 8. It is characterized in that: the piston 1 is located at the lower end of the umbrella handle main body 2; the ejection outlet 3 is located at the top of the umbrella handle main body 2; There is a one-way valve 5 between the powder storage chamber 4 and the umbrella handle main body 2; the air pressure valve 8 is installed at the outlet 3, and the air pressure valve 8 can only be opened when the air pressure in the umbrella handle main body 2 reaches a certain level; The piston 1 is equipped with an electric driving device and a power supply, and when the electric driving device is started, the piston 1 can move back and forth in a fast straight line, so that the gas in the umbrella handle mai...

Abstract

The invention relates to a police security appliance and provides a high-pressure powder ejection protection umbrella with a protection function. The high-pressure powder ejection protection umbrella comprises a piston 1, an umbrella handle main body 2, an ejection opening 3, a powder storage room 4, a un-directional valve 5, an umbrella cover 6 and ribs 7, and is characterized in that the piston 1 is located at the lower end of the umbrella handle main body 2; the ejection opening 3 is located at the top end of the umbrella handle main body 2; the powder storage room 4 is located at one side of the umbrella handle main body 2, and the powder storage room 4 and the cavity of the umbrella handle main body 2 are separated by the un-directional valve 5. According to the high-pressure powder ejection protection umbrella disclosed by the invention, a police umbrella and a high-pressure ejector are combined; the high-pressure powder ejection protection umbrella is simple in structure, and safe and convenient to use; the problem that the existing police ejector is short of the protection function is effectively solved.

Description

technical field [0001] The invention relates to a high-pressure powder injection protective umbrella with protection function. Background technique [0002] Existing police umbrella product has single function and lacks anti-riot function. [0003] Existing anti-riot jet self-defense devices used by the police have the problem of unsafe use. When using the jet, the irritating objects sprayed will be partially sprayed on the user due to the short spray distance, or because the rioters will use clothing, etc. to spray 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...
