Example 2
In the using process, it is found that because high-pressure gas is placed in the storage bottle 1, in the releasing process, the high-pressure gas can pass through the siphon 3 at a high speed and be released through the container valve 2, because the flowing speed of the fluid is high, in fact, friction force exists between the flowing fluid and the pipe wall of the siphon 3, the fluid can drive the siphon 3 to move upwards when flowing at a high speed, the siphon 3 cannot be close to the bottom surface of the storage bottle 1 enough, so that the fire extinguisher still has more residual quantity, if the specification of the spring 33 is directly increased, the volume of the spring 33 is inevitably increased obviously to influence the assembly, on the other hand, the adjustment of the elastic force of the spring 33 is not well controlled, the elastic force of the springs 33 of adjacent specifications is large, and the springs 33 of the used specifications are not easy to purchase.
In order to solve the problem, in the embodiment, the spring 33 is replaced by a biasing mechanism, the biasing mechanism includes an air storage ring 61, an outer air pipe 63, and an inner fixing pipe 64, as shown in fig. 5, the air storage ring 61 is an annular cavity, the top of the air storage ring 61 is provided with an air charging port 62 extending outward, air is charged into the air storage ring through the air charging port 62, the bottom of the air storage ring 61 is uniformly communicated with the outer air pipe 63, one end of the outer air pipe 63 is fixed on the bottom surface of the air storage ring 61, the other end of the outer air pipe 63 is open and is closed by the inner fixing pipe 64 inserted therein, one end of the inner fixing pipe 64 is inserted into the outer air pipe 63 to close the bottom end of the outer air pipe 63, the other end of the inner fixing pipe is fixed on the inner wall of the siphon 3, the inner fixing pipe 64 is compressed inward after receiving pressure by using air as an elastic medium, and the pressure of air is adjustable, so that the pressure of air can be increased appropriately to increase the pressure of the biasing mechanism on the siphon 3, the pressure adjustment is simpler and the cost is lower.
As shown in fig. 6, a blocking block 65 is further disposed at one end of the inner fixing tube 64 located at the outer air tube 63, and the outer air tube 63 is closed by the blocking block 65.
In addition, a bottom section of the inner fixing pipe 64 is fixed on the inner wall of the siphon tube 3, on one hand, the inner fixing pipe plays a role of connection and can move along with the movement of the siphon tube 3, on the other hand, the inner fixing pipe supports the siphon tube 3, and the strength of the siphon tube 3 is improved like a reinforcing rib.
Further, as shown in fig. 3-4, the external connection pipe 32 is provided with a limiting wheel 5, the limiting wheels 5 are uniformly distributed on the inner wall of the external connection pipe 32, the limiting wheels 5 are the same in size and are all in contact with the siphon pipe 3 to support the siphon pipe 3, and when the siphon pipe 3 moves, the limiting wheels 5 can also be matched with the siphon pipe 3 through rotation to avoid the siphon pipe 3 from deflecting in the using process.
