Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides an explosion-proof aerosol canister, including aerosol canister main part 1, aerosol canister main part 1 is including cover 2, can body 3 and

tank bottoms

6, 6 bottom axle centers departments of tank bottoms have locating plate 9 through 8 elastic connection of second spring, 9 top fixed mounting of locating plate have gag lever post 7, gag lever post 7 wears to establish 6 bottoms at the tank bottoms, and the gag lever post 7 outer table wall closely laminates with the interior table wall of second spring 8, when 1 inside pressure of aerosol canister main part is too big, atmospheric pressure can form certain thrust and promote gag lever post 7, gag lever post 7 atress can drive locating plate 9 and move down and compress second spring 8, break away from tank bottoms 6 until gag lever post 7, 6 tank bottoms 6 can appear the gap and make 1 inside pressure of aerosol canister main part can release this moment.

Specifically, as shown in fig. 1, the outer surface wall of the can body 3 is fixedly provided with a protection sleeve ring 4, the vertical end of the protection sleeve ring 4 is elastically connected with the can body 3 through a first spring 5, the protection sleeve ring 4 is fixedly arranged on the outer surface wall of the can body 3, the situation that an external substance directly contacts the can body 3 and damages the can body 3 is avoided, the first spring 5 between the can body 3 and the protection sleeve ring 4 supports the can body 3 through the elastic potential energy of the first spring 5, and the fatigue resistance of the can body 3 is improved.

Specifically, as shown in fig. 1, the tank cover 2, the tank body 3 and the tank bottom 6 are welded together, so that the overall stability of the aerosol tank body 1 is ensured.

Specifically, as shown in fig. 3, the protection lantern ring 4 is composed of a base plate layer 401 and a heat insulation layer 402, and when the protection lantern ring 4 protects the tank body 3, the temperature inside the tank body 3 is maintained stably through the heat insulation layer 402, so that the tank body 3 is prevented from being damaged due to temperature change.
