Principle of operation
Referring to fig. 1 to 9, when liquefied gas is first used and there is more liquefied petroleum gas in the first sealed space 230 of the inner shell 202, the air pressure in the inner space is higher, so as to push the piston plate 203 upward, but due to the presence of compressed air in the second sealed space 231, the piston plate 203 cannot be directly pushed to the top of the inner shell 202, when the liquefied gas in the first sealed space 230 is gradually used and reduced, the pressure is reduced, the piston plate 203 gradually slides downward, the internal volume of the first sealed space 230 is reduced, the pressure is maintained, and it is ensured that the liquefied gas in the first sealed space has sufficient air pressure until the piston plate 203 slides to the bottom of the inner shell 202, and the liquefied gas in the first sealed space is completely used.
When liquefied gas enters the detection channel 302 from the second circular channel 111, the gas drives the fan blade 303 to rotate, the fan blade 303 drives the fan gear 304 to rotate, the fan gear 304 drives the detection gear 308 engaged with the fan gear to rotate, the detection gear 308 drives the display gear set 309 to rotate, and the display displays the reading of the used liquefied gas.
When the outer layer takes place to leak simultaneously in the liquefied gas jar, grasp handle 4 and rotate outer shell 201, make and stagger each other the breach of revealing on outer shell 201 and the inlayer shell 202, temporary closure, the top export of netlike semicircular groove 207 breaks away from the cover of division board 206 on the outer shell 201 inner wall shelters from simultaneously, the strong glue of depositing of individual storage space 204 flows from the top down through netlike semicircular groove 207, breach department and air contact are revealing, solidify rapidly, thoroughly seal the gap between outer shell 201 and the inlayer shell 202, prevent to reveal once more.
