This embodiment is used for storing tea leaves, coffee and other items that should not be exposed to moisture. The pressure top tank 20 is re-covered on the storage bottom tank 10, and the gas in the storage bottom tank 10 is sucked out through the air suction and pressure reduction device 30, and the inner cavity of the storage bottom tank 10 will form a negative pressure state, and the pressure will be reduced. Under the action of negative pressure, the top tank 20 is sucked tightly with the storage bottom tank 10 and forms a sealed tank body under negative pressure. The moisture-absorbing sleeve tank 40 absorbs the moisture generated by the items in the tank at any time, so that the sealed tank body always maintains dry state.

As long as the screw type pressure relief valve 216 is turned, the air will enter the sealed tank body, and when the air pressure in the sealed tank body is balanced with the outside of the tank, the pressure-reducing top tank 20 can be taken off from the storage bottom tank 10, and the The items stored in the storage bottom tank 10 are taken out.

The casing base 21 is arranged at the center of the top plate of the step-down top tank 20, the telescopic opening 210 of the casing is arranged in the inner cavity of the casing base 21 and penetrates downward through the step-down top casing 20, and the positioning screw 211 is set At the center of the top plate of the tank base 21.

The jacket base 21 is not only the installation base of the moisture-absorbing jacket 40 , but also the grasping handle of the pressure-reducing roof tank 20 . The moisture-absorbing casing 40 is set in the telescopic opening 210 of the casing, and under the action of the cover knob 42, it extends or retracts into the telescopic opening 210 of the casing. The moisture in the tank is in a closed state when retracting into the telescopic opening 210 of the casing, and cannot absorb moisture.

The set card cover 22 includes an inner sleeve type card cover and an outer sleeve type card cover.

The set card cover 22 enables the step-down top tank 20 to be conveniently matched with the 10 mouth ferrules of the storage bottom tank. The outer ring of the mouth of 10 bottom tanks.

The air suction cylinder port 214 and the exhaust cylinder port 215 are arranged at the end of the air pumping cylinder body 212, and the air suction cylinder port 214 and the exhaust cylinder port 215 communicate with the bottom and top of the decompression top tank 20 respectively and are provided with a one-way valve 217 , the screw-type pressure relief valve 216 is arranged on the top of the decompression top tank 20 and communicates with the suction cylinder port 214 .

The pumping piston 31 is set in the pumping cylinder body 212, which can conveniently carry out the piston movement, and pump the gas in the closed tank to the outside of the tank, so that the pressure-reducing top tank 20 and the storage bottom tank 10 are combined into a closed tank in a negative pressure state body. One-way air valve 217 makes gas can only flow outwards from the sealed tank body, and can not flow into the sealed tank body from the outside. Only when the screw type pressure relief valve 216 is opened, gas can flow into the sealed tank body from the outside of the tank.

A combination buckle 311 is provided between the air extraction piston 31 and the air extraction cylinder body 212 .

Combination buckle 311 is arranged on the inlet of air extraction piston 31 tail outer ring and air extraction cylinder body 212, as long as rotate air extraction piston 31, just can disengage or fasten combination buckle 311, when combination buckle 311 is fastened, make air extraction Piston 31 is firmly sleeved in the air pumping cylinder 212, and when the combined buckle 311 is disengaged, it is convenient for the pumping piston 31 to do piston movement. During specific implementation, the air extraction piston 31 may also cooperate with the air extraction cylinder body 212 through threads or other combination methods.

The handle ferrule opening 310 and the driving sleeve 320 are arranged in a non-circular structure matched with each other, and an elastic shaft seat 322 is arranged in the middle of the elastic clip 321, and the elastic shaft seat 322 is connected with the middle part of the piston handle 32. The two ends of the clip 321 are respectively provided with a self-tightening chuck 323 and a release handle 324, and the self-tightening chuck 323 and the tripping handle 324 protrude outward from the inner cavity of the piston handle 32, and are located at the mouth of the handle sleeve 310. The end of the handle sleeve 213 is provided with a linkage jaw 312 , and the self-fastening chuck 323 is clamped with the linkage jaw 312 .

The handle ferrule opening 310 of the non-circular structure and the driving and rotating sleeve 320 can not only engage each other through ferrule, but also enable the piston handle 32 to conveniently drive the pumping piston 31 to rotate. The elastic shaft seat 322 makes the elastic clip 321 always in the state of clamping the self-clamping chuck 323, as long as the driving sleeve 320 is inserted into the handle sleeve opening 310 and pushed to the bottom, the self-clamping chuck 323 will be clamped and linked The jaw 312 makes the piston handle 32 and the air extraction piston 31 integral, and drives the air extraction piston 31 to rotate and perform piston movement. The piston handle 32 is set in the handle sleeve 213 for standby under normal conditions, and only when the closed tank is evacuated and depressurized, the piston handle 32 will be taken out from the handle sleeve 213 and combined with the pumping piston 31 into one. The elastic clip 321 clamps the linkage jaw 312 of the handle sleeve 213 , so that the piston handle 32 can be firmly set in the handle sleeve 213 . As long as the release handle 324 is squeezed tightly to make the self-tightening chuck 323 loosen the interlocking jaw 312, the piston handle 32 can be separated from the air pumping piston 31 and the handle sleeve 213.

As long as the gland knob 42 is turned, the push-pull screw rod 41 can drive the moisture-absorbing casing 40 to stretch out or retract into the casing telescopic opening 210 . Since the articles are easy to separate moisture under the negative pressure state, when the sealed tank body forms a negative pressure state, then push the moisture-absorbing sleeve 40 out of the expansion port 210 of the sleeve tank to absorb moisture more easily and keep the inside of the sealed tank in a dry state . The moisture-absorbing sleeve 40 is retracted into the telescopic opening 210 of the sleeve, and is kept closed under the action of the sealing ring plate 430 and the sliding sealing ring 431. When the pressure-reducing top tank 20 is opened, the moisture-absorbing sleeve 40 will not absorb the sealed tank outside moisture.

The moisture-absorbing cover tank 40 will reduce the ability to absorb moisture after use. As long as the moisture-absorbing cover tank 40 is disassembled from the pressure-reducing top tank 20, the desiccant can be easily replaced to maintain a better moisture-proof function.

To sum up: this embodiment solves the problem that the storage tank in the prior art can only seal and store items but cannot absorb moisture in the tank, and provides a negative pressure moisture-absorbing storage tank that can replace the existing product.
