The utility model discloses an air pressure water outlet device of an electric thermos
bottle. The air pressure water outlet device comprises a
barrel and an upper cover, a containing cavity is formed in the cylinder body, and a mounting cavity is formed in the position, above the containing cavity, of the top of the cylinder body; the upper cover is arranged in the mounting cavity, and a soft bag is arranged at the top of the upper cover; the first blocking piece can be pushed by gas in the soft bag to move in the gas outlet channel, external gas can flow into the gas
inlet channel when the pressing of the soft bag is released, the second blocking piece can be pushed by the gas entering the gas
inlet channel to move upwards, the gas enters the soft bag, and the gas can flow into the gas outlet channel. The internal air pressure drives the
water source to be discharged from the interior of the water outlet; when water flows out of the water outlet, the electric pump pumps water, even if the first blocking piece of the air outlet channel moves downwards and the second blocking piece in the air
inlet channel moves upwards, air outside the
barrel enters, the air pressure in the container is the same as that of the
barrel, the water outlet amount is larger, the working load of the electric pump is reduced, the service life of the electric pump is prolonged, and the water outlet amount is increased.
