Working principle: When it is in the initial state, the bottom end of the ratchet seals the air hole. When vacuuming is required, turn the cap clockwise to drive the ratchet to rotate. The opening at the bottom of the ratchet communicates with the air hole, and the limit post on the ratchet pushes the piston upward. Movement, at this time, the air in the cup is sucked into the inner core through the air hole, the air in the inner core is sucked out through the one-way valve, and the cup cover is vacuumed for many times to the air in the cup by rotating the cap for many times until The cap cannot be rotated, indicating that the air in the cup has been exhausted, and the vacuuming work is completed. When the cup lid needs to be opened, the pressure relief button needs to be pressed down, and the pressure relief valve will move down, and the air will pass through the pressure relief valve and the mounting column. The gap created between the inner walls enters the cup, at which point the lid can be opened.
