A kind of water bag of built-in U-tube
Technical field
The utility model belongs to water storage device technical field, especially relates to a kind of water bag of built-in U-tube.
Background technology
Traditional water purifier carries water storage device, and one kind is that water enters a housing after filtration system, and housing is big
Coefficient of expansion diaphragm separates into an air bag and a water cavity, by compression and swelling gasbag, the big diaphragm retracts expanding system
Realize water inlet and outlet in water cavity with swelling to delivery port.Another kind is that water enters one and air after filtration system
Can unidirectional or diconnected water tank, water is stored in water tank, carries out the water discharge in water tank by intake-outlet and stores.
First kind of way is pressure water filling leads to that space availability ratio is not high cannot to meet built-in demand due to the feature of itself, by
In long-term work in the larger environment of pressure, easy leak and booster, dangerous high, just it is not easy when leakage in air bag
Realize entering and discharging of water, second way water inlet and water outlet more bother, and the water in two ways is all carried out with air
Contact, for a long time after be easily contaminated, additionally, the water tank of water storage device of the prior art and water bag are not easily separate, needs
Dismantled, water bag is changed and more bothered, and usually can bring bubble in water bag into, not only can be to water bag when gas gets more and more
Build-up of pressure, also results in water and is not easy to flow in water bag, global design is reasonable not enough.
In order to improve to prior art, people have carried out long-term exploration it is proposed that various solution.
For example, Chinese patent literature discloses a kind of water storage device and water purifier [application number:CN201510372921.5], including flexible
Water bag, top cover, tank body and support member;Described flexible water bag has the sack flowing into or out that supplies water;Described support member is annularly arranged,
Described sack is fixedly connected with described support member;Described tank body is in the hollow tube-shape of one end open;Described top cover include lid and
The cover rim of the opening place end projection from described lid to described tank body;The opening place end of described tank body is removable with described cover rim
Unload connection and form the accommodating cavity housing described flexible water bag, and described support member is compressed and is fixed on described tank body opening and is located
Between the end face at end and described lid.
Although such scheme to some extent solves the deficiencies in the prior art, the water tank of water storage device and water bag
Be not easily separate, need to be dismantled, water bag is changed and more bothered, and usually can bring bubble in water bag into, when gas increasingly
Not only water bag build-up of pressure can be also resulted in water and is not easy to flow in water bag, global design is reasonable not enough when many.
