[0016] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of protection of this utility model.

[0017] Please see Figure 1 , Figure 2 and Figure 3A flow divider structure for a battery compartment detector, installed inside the detector, includes a flow divider seat 10 and an on / off piston 20. The flow divider seat 10 has a wide flow channel 11 and a narrow flow channel 12 that are connected in a straight line, one wide and one narrow. The flow divider seat 10 has an air outlet 13 at its top, communicating with the middle section of the wide flow channel 11. The flow divider seat 10 has a first external interface 14 and a second external interface 15 at its bottom, extending out of the detector. The first external interface 14 is connected to the end of the wide flow channel 11 adjacent to the narrow flow channel 12, and the second external interface 15 is connected to the narrow flow channel 12 away from the wide flow channel 11. One end is connected to the corresponding end; a capping cylinder 16 is installed in the wide flow channel 11, which blocks the end of the wide flow channel 11 away from the narrow flow channel 12. A positioning cylinder channel 161 and a reset cylinder channel 162 are formed sequentially in the direction of the narrow flow channel 12. The reset cylinder channel 162 is provided with several openings 101 connected to the air outlet 13 at one end adjacent to the positioning cylinder channel 161. The on / off piston 20 is arranged in the wide flow channel 11 and can move back and forth relative to the capping cylinder 16, and can block the narrow flow channel 12 or the reset cylinder channel 162 as it moves back and forth.

[0018] Furthermore, in this embodiment, the switching piston 20 forms a piston head 21 for blocking the narrow flow channel 12 or the reset cylinder channel 162 and a piston rod 22 that is sequentially inserted into the reset cylinder channel 162 and the positioning cylinder channel 161. A reset member 23 is sleeved on the piston rod 22. The two ends of the reset member 23 respectively abut against one end of the reset cylinder channel 162 adjacent to the positioning cylinder channel 161 and the piston head 21, providing driving force to the piston head 21, so that the piston head 21 maintains the tendency to block the narrow flow channel 12. When the piston head 21 blocks the narrow flow channel 12, the first external interface 14 is connected to the wide flow channel 11, and when the piston head 21 blocks the reset cylinder channel 162, the first external interface 14 is connected to the narrow flow channel 12.

[0019] Furthermore, in this embodiment, the diameter of the piston rod 22 is matched with the diameter of the positioning cylinder channel 161 to improve the stability of the on / off piston 20 when it moves in and out relative to the sealing cylinder 16.

[0020] Furthermore, in conjunction with reference Figure 4 In this embodiment, the battery compartment detector diversion structure includes a puncture valve 30; a diaphragm 301 is provided at the connection between the narrow flow channel 12 and the second external interface 15; the puncture valve 30 is installed on the top of the diversion seat 10, and the puncture needle of the puncture valve 30 can penetrate into the connection between the narrow flow channel 12 and the second external interface 15 to puncture the diaphragm 301.

[0021] Furthermore, in this embodiment, a pressure cylinder 40 is provided above the diaphragm 301 at the connection between the narrow flow channel 12 and the second external interface 15, and the pressure cylinder 40 is provided with a plurality of vertically shaped pressure holes 41.

[0022] Furthermore, in this embodiment, the reset channel 162 has a horn-shaped opening at one end facing the narrow flow channel 12, and the piston head 21 of the switching piston 20 is shaped to match the horn-shaped opening, so that when the piston head 21 blocks the narrow flow channel 12, the first external interface 14 can be connected to the wide flow channel 11 with a gap.

[0023] Furthermore, in this embodiment, the reset member 23 is a spring member.

[0024] Understandably, the method of using the battery compartment detector diversion structure of this utility model is as follows: When the piston head 21 blocks the narrow flow channel 12, a gas passage for gas delivery is formed by connecting the first external interface 14, the wide flow channel 11, the reset cylinder channel 162, the through port 101, and the outlet 13; while when the piston head 21 blocks the reset cylinder channel 162, a delivery channel for extinguishing agent delivery is formed by connecting the second external interface 15, the narrow flow channel 12, the connection between the first external interface 14 and the wide flow channel 11, and the first external interface 14. In this way, the gas and extinguishing agent are diverted and delivered separately, and when the extinguishing agent is delivered, the delivery pressure of the extinguishing agent is greater than the driving force of the reset member 23, thereby pushing the piston head 21 to block the reset cylinder channel 162.

[0025] In summary, the battery compartment detector diversion structure of this utility model, through the cooperation between the diversion seat 10 and the on / off piston 20, allows the on / off piston 20 to move forward and backward relative to the sealing cylinder 16, thereby blocking the narrow flow channel 12 or the reset cylinder channel 162, achieving the diversion and delivery of gas and extinguishing agent, and making its functions more diverse.
