Flexible water bag assembly and water purifying equipment provided with same

Abstract

The invention discloses a flexible water bag assembly and water purifying equipment provided with the same. The flexible water bag assembly comprises a flexible water bag and an air exhausting structure. A water storage cavity is defined in the flexible water bag assembly, and the upper portion of the flexible water bag assembly is provided with an opening communicating with the water storage cavity. The air exhausting structure is arranged at the opening so as to exhaust air in the water storage cavity and comprises a shell and a sealing part. An air exhausting cavity is defined in the shell. The shell is provided with a water and air inlet and an air exhausting opening which communicate with the air exhausting cavity, the water and air inlet communicates with the opening, and the air exhausting opening is formed in the upper portion of the shell. The sealing part is movably arranged in the air exhausting opening in the vertical direction. The sealing part opens the air exhausting opening when the air pressure in the air exhausting opening is larger than the air pressure outside the shell. The sealing part closes the air exhausting opening when the air pressure in the air exhausting opening is equal to the air pressure outside the shell. According to the flexible water bag assembly in the embodiment, no electromagnetic valve is needed, the number of parts is small, the structure is simple, occupied space is small, and cost is low.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, and more specifically, to a retractable water bag assembly and a water purification equipment with the same. Background technique [0002] In water purification equipment, replacing the pressure tank with a retractable water bag has many advantages, but the exhaust structure restricts the miniaturization of the water purification equipment. The bags are connected together. When the power is first turned on, the solenoid valve is always open to exhaust. When the water level in the retractable water bag reaches a certain height, the water production will stop, and the solenoid valve will be closed at the same time. The solenoid valve is basically closed during later use. This solution Although the purpose of exhaust can be achieved, the cost is high and it takes up a lot of space. During the expansion and contraction of the water bag, the pipeline is dragged, which is easy to b...

[0002] In water purification equipment, replacing the pressure tank with a retractable water bag has many advantages, but the exhaust structure restricts the miniaturization of the water purification equipment. The bags are connected together. When the power is turned on for the first time, the solenoid valve is always open to exhaust. When the water level in the retractable water bag reaches a certain height, the water production will stop, and the solenoid valve will be closed at the same time. The solenoid valve is basically closed during later use. This solution Although it can achieve the purpose of exhausting, but the cost is high and it takes up a lot of space. During the expansion and contraction of the water bag, the pipeline is dragged, which is easy to be eccentric and affects the work.
