Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings, but the embodiments of the present invention are not limited thereto.

As shown in figure 1, a tubular atomizer for in lithium cell production line, energy storage container, install on the fire extinguishing agent conveyer pipe in the battery protection district, fire extinguishing agent conveyer pipe and fire extinguishing agent bottle group link for the atomizer is whole to be horizontal or vertical placing, reduces the space that occupies the battery protection district. When the lithium battery is spontaneously combusted, the gas fire extinguishing medium flowing through the fire extinguishing agent conveying pipe forms a fine mist fire extinguishing medium after passing through the atomizing nozzle, and the fire is quickly extinguished.

Combine fig. 1 to fig. 3, it is concrete, atomizer includes integrated body 1 and shower nozzle inlay 2, integrated body 1 wholly is cylindricly, the circulation inner chamber 3 and the internal thread mounting hole 4 that the intercommunication set up are seted up to integrated body 1 inside coaxial, the internal diameter of internal thread mounting hole 4 is greater than the internal diameter of circulation inner chamber 3, and internal thread mounting hole 4 leans on outer the setting, be convenient for can dismantle threaded connection with the fire extinguishing agent conveyer pipe, and be convenient for during gaseous fire extinguishing medium among the fire extinguishing agent conveyer pipe gets into integrated body 1. Still spaced apart being equipped with two shower nozzle inlay mounting grooves 5 that set up with 3 intercommunications of circulation inner chamber on the integrated body 1, shower nozzle inlay mounting groove 5 specifically is the internal thread groove, and lies in shower nozzle inlay mounting groove 5 department on the outer wall of integrated body 1 and be formed with spacing butt concave 6. Install when shower nozzle inlay 2, install shower nozzle inlay 2 screw thread in shower nozzle inlay mounting groove 5, until

shower nozzle inlay

2 and 6 butt settings of spacing butt concave surface. In this embodiment, the nozzle inlay 2 is formed with atomizing orifices arranged at intervals, and the nozzle inlay 2 is higher than the integrated pipe body 1 and slightly protrudes relative to the integrated pipe body 1.

For the leakproofness between improvement shower nozzle inlay 2 and the integrated body 1, be equipped with seal ring between shower nozzle inlay 2 and the spacing butt concave surface 6, not seen in the figure, seal ring can set up to the platykurtic.
