6. A fire extinguisher valve bump guard as claimed in claim 2 wherein: the outer diameter of the sleeve (385) is 1.2 times the diameter of the side opening (37).
7. A method of collision avoidance of a fire extinguisher valve according to claim 3, comprising the steps of:
s1, when a fire extinguisher is placed at a fire-fighting specified place and is impacted by other objects or collides in the process of holding and transferring, once the squeeze valve head (2) at the top of the fire extinguisher is subjected to external acting force, the squeeze valve head (2) can deflect in the range of a beam-converging opening (35) along a ball cup (31) through an airtight ball (34), so that the squeeze valve head (2) is prevented from being hard collided with external objects, and the self-displacement is utilized to absorb impact force and reduce stress;
s2, when collision aiming at the squeeze valve head (2) occurs in the placing process of the fire extinguisher, the offset airtight ball (34) is transferred to a side curved surface from a bottom flat opening, so that the airtight ball (34) is propped against the sleeve (385) to move downwards along the bracket (384), and the steel column (381) is driven to rotate by utilizing threads (387) between the sleeve (385) and the steel column (381), at the moment, two balancing weights (383) at the bottom of the steel column (381) synchronously rotate, and shake possibly generated by the inertial opposite impact steel bottle (1) generated by centrifugal movement of the balancing weights (383) is overcome;
s3, when the fire extinguisher in a placed state is collided and the steel cylinder (1) is tilted, the steel column (381) coaxial with the inside of the fire extinguisher is tilted horizontally, when the balancing weight (383) on the ring seat (3821) faces downwards in the rolling process of the steel cylinder (1), the balancing weight naturally sags along with gravity, the lantern ring (3822) deflects and enables the latch (3824) to be separated from the clamping groove (3825), the locking of the ring seat (3821) and the steel column (381) is released, the balancing weight (383) can keep a sagged posture along the autorotation steel column (381) through the ring seat (3821), and the balancing weight does not deflect at a large angle along with the rolling of the steel cylinder (1), so that the inner gravity center of the steel cylinder (1) is automatically transferred below a central axis rotating line, and the rolling degree of the steel cylinder (1) can be effectively reduced by increasing the rotating load of the steel cylinder (1).
S4, when a user holds the fire extinguisher to extinguish fire, the fire extinguisher can actively push the pressure trigger valve head (2) to deflect back and forth and drive the steel column (381) to rotate, and liquid carbon dioxide in the steel bottle (1) is stirred through two balancing weights (383) at the bottom of the steel column (381).
