Description

Fire extinguisher intake structure

The invention relates to a fire extinguisher intake structure, which mainly relates to a fire extinguisher intake structure with better safety and labor saving operation.

Conventional fire extinguishers mainly contain fire-extinguishing powder in pressurized cylinders. When used, the valve can be pressed so that high-pressure gas can be injected with fire-extinguishing powder to extinguish the fire. However, the pressure inside the cylinder will decrease with time, and when the pressure is insufficient, the gas needs to be refilled. Therefore, maintenance and filling inconvenience are missing.

In order to improve the foregoing situation, there is currently a fire extinguisher with a high-pressure steel cylinder, and the bottle body of the fire extinguisher is filled with fire-extinguishing powder, and the bottle body has an outlet, an air inlet, and a high-pressure steel cylinder is externally connected to the air inlet, and the position of the high-pressure steel cylinder is corresponding. Set the striker and button, and set the cover that can be opened and closed above the button, so that the cover can be covered when the cover is closed, and the button can be prevented from being accidentally touched. When the cover is used, the cover can be opened and the button can be pressed. The needle can be displaced to pierce the reserved opening of the high-pressure cylinder, and the gas of the high-pressure cylinder can be introduced into the bottle body to extinguish the fire-extinguishing powder in the bottle from the outlet.

However, when the foregoing structure is used, it is required to apply pressure to make the striker puncture the high-pressure steel cylinder, which still causes inconvenience to the force application and the force may be less likely to be pressed smoothly, and the cover may be easily opened by the non-user, and may still cause the button Exposed and mistakenly touched.

SUMMARY OF THE INVENTION The object of the present invention is to provide a fire extinguisher intake structure that is safer and more economical to operate.

　　 The fire extinguisher of the present invention comprises a bottle body, an upper cover, a high pressure steel bottle and an air intake control unit, wherein the bottle body has a chamber for accommodating the fire extinguishing powder, the upper portion has an opening, and the central portion is provided with a conduit, and the inlet under the conduit has an inlet; The upper cover can cover the opening above the bottle body, the upper part has a grip, and the inner tube is arranged to communicate with the conduit, and an outlet passage is connected with the inner tube and the chamber, and the outlet channel is connected to the outlet tube, and the outlet tube is connected a valve is arranged, and an inlet passage communicating with the bottle body chamber is disposed on the upper cover, and a first joint portion is disposed, and an air inlet slot communicating with the intake passage is disposed at the first joint portion, and is further disposed at one end of the intake passage Opening a second joint portion, and the second joint portion has two parallel side walls, a bottom wall is provided below, and a perforation is provided at a position corresponding to the intake slot hole of the bottom wall, and a pivot hole is disposed at an inner side of the two side walls, and the outer side Positioning the tip hole; the top of the high pressure steel cylinder is engaged with the first joint portion of the upper cover, and the reserved opening of the high pressure steel cylinder corresponds to the intake slot; and the intake control unit includes a check valve, a striker, a spring a blocking piece, a pressing rod, a switch handle, a plug, a barometer, wherein the check valve is disposed at an inner side of the intake passage of the upper cover, and prevents the gas of the intake passage from flowing backward, and the striker The utility model is disposed at the piercing position of the air inlet slot and the second joint portion, and has a needle portion at the bottom end which can pierce the reserved opening of the high-pressure steel cylinder, and is provided with a concave air groove at the side edge of the needle portion, and is disposed at the top end a top portion of the perforation; the bottom end of the spring is disposed at a bottom wall of the second joint portion, and the top end abuts against the blocking piece, and the center of the blocking piece has a through hole through which the striker can be inserted, and the needle is inserted when the spring is not compressed. The needle portion does not pierce the reserved opening of the high-pressure steel cylinder; the pressing rod is pivotally connected with the pivot hole of the second joint portion, and the rod portion is disposed, and the outer edge of the rod portion is protruded to abut against the top portion of the striker. The pressing portion is disposed on the outer edge of the pressing portion to facilitate the pressing portion of the pressing portion to resist the displacement of the striker; and the switch handles the grip portion, and the grip portion is disposed outside the upper cover and is held The two sides of the second portion extend inwardly to be coupled with the pressing rod, and the distance between the grip portion and the rod portion of the pressing rod And the insertion tip may be inserted tip hole, and jumper switch to mention the operation limit; and gauge provided in the intake passage of the outer opening position, and the adhesion of the opening.
