Problems solved by technology

[0002] The structure of the sprinkler head used for lithium battery box fire extinguishing in existing new energy buses has the following characteristics: 1. It only has the ordinary spraying function; Dust, water, oil and other harmful substances in the environment have no direct isolation effect, and can only rely on the filter device installed on the pipeline, which has limited effect and may easily cause nozzle blockage; 4. Inconvenient assembly and disassembly
Therefore existing nozzle has the following disadvantages: one, the nozzle nozzle is easily blocked, which affects the spray effect; two, the fixed way connected with the nozzle takes up a lot of space, and the position is easily limited; three, it is not suitable for airtight, protective Equipment with high grade requirements; 4. When the nominal diameter of the nozzle is less than 10mm, it is necessary to install a filter on the main pipe or branch pipe, and the installation and maintenance costs are more

Embodiment 1

[0045] Such as Figure 1-5 As shown, in Embodiment 1, a waterproof and breathable nozzle provided by the present invention includes a nozzle body 1, a gas-permeable membrane 2 and a fixing member 3; the nozzle body 1 is provided with a central Holes 104 and internally threaded holes 105; the internal diameter of the internally threaded hole 105 is greater than the internal diameter of the central hole 104; the outer surface of the nozzle body 1 is sequentially arranged as a connecting section 101, a transition section 102 and The first external thread section 103; the outer contour dimension of the transition section 102 is larger than the outer contour dimension of the connecting section 101 and the first external thread section 103; the gas-permeable membrane 2 is installed on the nozzle body 1 through the fixing member 3 Inside threaded hole.

[0046]In the first embodiment, the fixing part 3 includes a spraying part housing 301, a protective cover 302 and a sealing ring 3...

Embodiment 2

[0065] Such as Figure 7-11 As shown, the difference between embodiment two and embodiment one is as follows:

[0066] 1. The fixing part 3 includes a washer 4 and a fastening screw 5. The fastening screw 5 is provided with a through hole 501 and an inner hexagonal groove 502 in sequence from the center of one end to the center of the other end; the main body of the nozzle In the internal threaded hole 105 of 1, a said washer 4, said air-permeable membrane 2, another said washer 4 and said fastening screw 5 are installed sequentially from the bottom of the hole to the orifice, wherein the fastening screw 5 is connected with the nozzle main body 1 The inner threaded hole 105 of the spray head body 1 is threaded to effectively install the gasket 4 and the gas permeable membrane 2 in the inner threaded hole 105 of the spray head body 1 . In addition, the inner hexagonal groove 502 on the fastening screw 5 is provided to facilitate the assembly and disassembly of the fastening sc...

Embodiment 3

[0079] Such as Figure 13-15 As shown, the difference between the third embodiment and the first embodiment is: the transition section 102 is provided with an annular boss 1023 on the end surface close to the first external thread section 103; A plurality of screw holes 1024 are evenly distributed on the circumference of the end surface of the inner diameter of the boss 1023 , and the screw holes 1024 pass through both ends of the transition section 102 . In addition, compared with the first embodiment, the third embodiment has the following structure: the first external thread section 103 is covered with a silicone pad 9, and the silicone pad 9 is provided with a number of screw holes 1024 that are opposite to the screw holes 1024 and have the same number. Cylindrical hole; the fastening screw 10 covers the first O-ring 11 and passes through the screw hole 1024 of the transition section 102 and the cylindrical hole of the silicone pad 9 in sequence.
