Large-barrel water pressing device with two one-way valves

Abstract

The existing large-barrel water pressing device is a product which is characterized in that air is pumped in a barrel to improve air pressure in the barrel, and water in the barrel is pressed out of the barrel by utilizing the fortified air pressure, has the defects that along with the descent of a water surface, more and more air needs to be led in, water is more and more difficult to press, and a water outlet action cannot be interrupted in time when the water is pressed, so that inconvenience is brought to a user. A large-barrel water pressing device with two one-way valves is characterized in that an annular plicated airtight cylinder is adopted as a water storage container; the two one-way valves are respectively arranged on a water outlet pipe and a water absorption pipe; an anti-corrosion spring is arranged in the annular plicated airtight cylinder, so that the adverse effect brought to water quality caused by chemical reaction due to long-time contact of the spring and the water is prevented. When the water is pressed, the flow of water outlet can be effectively controlled, and the labor-saving effect is achieved; when a hand is released, water absorption is carried out by utilizing counterforce of the spring, and the labor-saving effect is also achieved; the system does not take the aim of improving the air pressure in the barrel as the main aim, so that strict requirement on the air impermeability at a joint part of the large-barrel water pressing device and the barrel body does not exist.

Description

Technical field [0001] It belongs to the field of daily necessities. technical background [0002] The existing large bucket water pressure water device is a product that pumps air into the bucket to increase the air pressure in the bucket, and uses the enhanced air pressure to press the water in the bucket out of the bucket; the disadvantage is that as the water level decreases, the more gas that needs to be introduced As more and more water is pressed, it is more and more strenuous to press the water, and the water discharge action cannot be interrupted in time when the water is pressed out, which brings inconvenience to the user. Contents of the invention [0003] The technical problems to be solved are: [0004] The rebound force of the spring is used to suck water into the closed cylinder, and two one-way stop valves are used to control the flow of water, which can instantly stop the water outlet action and reduce the labor intensity of the water pressure.
