Description

Technical Field

[0001] The utility model relates to the technical field of moisture-proof cans, in particular to a moisture-proof can for storing technical drugs Background Art

[0002] A moisture-proof can, as the name implies, is a storage device that can prevent moisture. Moisture-proof cans are widely used in the field of storing technical drugs. However, the existing moisture-proof cans have a too simple structure and poor moisture-proof ability

[0003] The technical solution disclosed in the Chinese patent with the publication number CN212638264U preliminarily seals the moisture-proof can by screwing the bottle cap, and the second thread groove on the bottle cap engages with the first thread groove on the bottle body, so as to prevent moisture in the outside air from entering the inside of the bottle body and causing the medicine to deteriorate. Then, by pressing the rubber air bag multiple times, the rubber air bag compresses and drives the second plug to move downward and compress the second return spring. The air inside the rubber air bag is discharged through the exhaust hole. At the same time, the first return spring drives the first plug and the first cylinder to block the suction hole, preventing the air inside the rubber air bag from flowing back into the bottle body. When the rubber air bag is released, the rubber air bag drives the first plug to move upward under the action of elasticity and sucks out the air inside the bottle body through the suction hole, achieving the effect of simple and convenient one-way exhaust and moisture-proof

[0004] However, this device still has deficiencies: the bottle cap and the bottle body of this moisture-proof can are still connected in a threaded connection form, which is rather troublesome to open and close Summary of the Utility Model

The button 4 is connected to a wedge-shaped block 5 with a wedge-shaped inclined surface facing the bottom of the tank body 1 through a tensioning assembly A. The wedge-shaped clamping block 5 passes through the through hole 201 and is clamped into the clamping groove 101. The tensioning assembly A includes a telescopic rod and a spring A. An inner cavity is provided inside the button 4, and a sliding groove communicating with the inner cavity is provided on the side surface of the button 4. The telescopic rod is located inside the inner cavity, and the wedge-shaped clamping block 5 is located inside the sliding groove and is slidably connected to the inner wall of the sliding groove. The two ends of the telescopic rod are respectively connected to the inner wall of the inner cavity and the wedge-shaped clamping block 5. The spring A is sleeved outside the telescopic rod, and the two ends of the spring A are respectively abutted against the inner wall of the inner cavity and the wedge-shaped clamping block 5. The tensioning assembly B includes, but is not limited to, a spring B. The two ends of the spring B are respectively abutted against the bottom of the button 4 and the bottom of the cylindrical groove. The tensioning assembly B connects the cover body 2 and the button 4 to prevent the button 4 from automatically sinking. The ventilation assembly includes a guide tube 3 and a hollow column 6. The guide tube 3 is connected to the end of the cover body 2 inserted into the tank body 1, and a side hole A 301 communicating with the inside thereof is provided on the side surface of the guide tube 3. The bottom of the hollow column 6 is closed. The hollow column 6 is connected to the bottom of the button 4 and is inserted into the guide tube 3. The outer wall of the hollow column 6 is attached to and slidably connected to the inner wall of the guide tube 3, and a side hole B 601 is provided on the side surface of the hollow column 6 along the radial direction of the side hole A 301. The side hole B 601 is communicated with the side hole A 301 in the state of pressing the button 4 downward. A diversion channel communicating with the inside of the hollow column 6 is provided on the button 4, and a dust-proof net 7 is provided inside the opening of the diversion channel. In the state of pressing the button 4 downward, the tank body 1 is communicated with the outside. Two fixing seats 9 are symmetrically arranged about the axis of the cover body 2. The fixing seats 9 are rotatably connected to a rotating shaft 10, and the rotating shaft 10 is connected to a handle 11. There are two rotating shafts 10.
