Embodiment 1

[0016] Example 1: Such as figure 1 As shown, a high-pressure powder protection injector includes a piston 1, a main body 2, an ejection port 3, a powder storage chamber 4, and a one-way valve 5, and is characterized in that: the inside of the main body 2 has a cavity; The piston 1 is connected to the cavity of the main body 2; the ejection port 3 is located at the front of the cavity of the main body 2; There is a one-way valve 5 in the space between the cavities.

Embodiment 2

[0017] Example 2: Such as figure 1 As shown, a high-pressure powder protection injector includes a piston 1, a main body 2, an ejection port 3, a powder storage chamber 4, a one-way valve 5, and an air pressure valve 6. It is characterized in that: the interior of the main body 2 is empty Cavity; the piston 1 is connected to the cavity of the main body 2; the ejection port 3 is located at the front of the cavity of the main body 2; the powder storage chamber 4 is located around the front end of the cavity of the main body 2 and contains irritating powder. There is a one-way valve 5 at a distance from the cavity of the main body 2; the air pressure valve 6 is installed in the cavity of the main body 2 and connected to the ejection port 3; the piston 1 is equipped with an electric drive device and a power supply, and the electric drive device is activated. The piston 1 can quickly move back and forth in a straight line, so that the gas in the umbrella handle main body 2 forms ...

Embodiment 3

[0018] Example 3: Such as figure 1 As shown, a high-pressure powder protection injector includes a piston 1, a main body 2, an ejection port 3, a powder storage chamber 4, a one-way valve 5, an air pressure valve 6, and a switch 7, and is characterized in that: the main body 2 There is a cavity inside; the piston 1 is connected to the cavity of the main body 2; the ejection port 3 is located at the front of the cavity of the main body 2; The powder is separated from the cavity of the main body 2 by a one-way valve 5; the air pressure valve 6 is installed in the cavity of the main body 2 and connected to the ejection port 3; the piston 1 is equipped with an electric drive device and a power supply to start the electric The driving device, the piston 1 can move back and forth quickly in a straight line, so that the gas in the umbrella handle main body 2 forms a high-pressure gas; a switch 7 is installed between the piston 1 and the main body 2, and the switch 7 can lock the pi...

Abstract

The invention relates to a police security appliance and provides a high-pressure powder protection ejector, which comprises a piston 1, a main body 2, an ejection opening 3, a powder storage room 4 and a un-directional valve 5, and is characterized in that a cavity is formed in the main body 2; the piston 1 is connected with the cavity of the main body 2; the ejection opening 3 is located at the front part of the cavity of the main body 2; the powder storage room 4 is located at the periphery of the front end of the cavity of the main body 2, and the powder storage room 4 and the cavity of the main body 2 are separated by the un-directional valve 5. By taking high-pressure gas generated by pushing a manual push piston or an electric piston as the power of the ejector, the ejection power of the high-pressure powder protection ejector disclosed by the invention is not limited and can be continuously supplied and enhanced, and therefore the problems that the power of the existing police anti-riot ejection self-protection device is limited and weak, and the ejection power cannot be continuously enhanced are solved.

Description

technical field [0001] The invention relates to a high-pressure powder protection injector. Background technique [0002] Existing anti-riot jet self-defense device is based on the limited propellant or high-pressure gas cylinder of its loading as the launch power, its power is limited and weak, and the launch power cannot be continuously supplied and strengthened. For example, the propellant of the anti-riot jet self-defense device forms a pressure in the injector tank, so that the stimulant can be sprayed out through the valve; the volume of the injector is small, and the filling amount of the propellant is relatively small, so the spray distance is also short. The spraying distance is only 3~6m. The existing knapsack anti-riot jet disperser uses high-pressure gas as the power source, and must be equipped with a high-pressure gas cylinder. If the high-pressure gas is used up, a new high-pressure gas cylinder must be replaced; there is also a heavy load, which is inconven...
