[0038] lemon powder arranged in the air bag 11;

[0039] a cover 12 detachably mounted on the air bag 11 and used for plugging the opening, the cover 12 being made of flexible material; and

[0040] a soda water bag arranged in the cover 12 and arranged on the top of the steel wire mesh 113, the soda water bag being squeezed to be broken and the soda water in the soda water bag flowing into the air bag 11 through the steel wire mesh 113 and contacting with the lemon powder, so that gas is generated and the air bag 11 and the cover 12 are inflated.

[0041] Preferably, the fixing rod 13 is an iron rod.

[0042] As a preferred embodiment of the present application, it further comprises a first fixing cylinder 111 fixed in the air bag 11 and sleeved on the fixing rod 13, and a plurality of first partition plates 112 arranged at intervals and connected between the outer wall of the first fixing cylinder 111 and the inner wall of the air bag 11, the plurality of first partition plates 112 dividing the space between the air bag 11 and the first fixing cylinder 111 into a plurality of first compartments, and the lemon powder is arranged in the plurality of first compartments.
