WATER STORAGE TANK FOR WATER PURIFYING SYSTEM
A water storage tank for water purifying system is disclosed. It mainly includes a solid housing and at least one air bag. The solid housing has a liquid storing space for storing liquid. The air bag being positioned in the liquid storing space and the air bag is movable inside. This air bag will expand or shrink depending upon the pressure in the liquid storing space. So, this invention can be modified from an existing storage tank. There is no water leakage problem causing by the membrane of the storage tank. In addition, it is easy to replace the air bag. In addition, the overall cost is extremely low.

1. Field of the Invention
The present invention relates to a water storage tank for water purifying system. Particularly, it relates to a water storage tank for water purifying system that has at least one air bag. This invention can be modified from an existing storage tank. There is no water leakage problem causing by the membrane of the storage tank. It is easy to replace the air bag. In addition, the overall cost is extremely low.
2. Description of the Prior Art
Referring to
There are many kinds of traditional storage tanks 97. Two of them are described below. As shown in
[1] It is easy to become loose or cause leaking.
[2] It will cause air leaking problem. After it is used for a long time, the air leaking problem will occur at the inflating portion 976 due to aging.
[1] The loose problem or water leaking problem will happen at the welding portion. As illustrated in
[2] The manufacturing cost is relatively high. The structure of the traditional storage tank with welding seam is complicated. Plus, the required parts are more. So, the manufacturing cost is relatively high.
SUMMARY OF THE INVENTIONThe object of the present invention is to provide a water storage tank for water purifying system. In which, this invention can be modified from an existing storage tank. There is no water leaking problem causing by the membrane of the storage tank. It is easy to replace the air bag. In addition, the overall cost is extremely low. Hence, it can solve the problems happened in the traditional one, such as loose problem, water leaking problem, as well as high manufacturing cost.
The present invention is a water storage tank for water purifying system comprising:
a solid housing having a liquid storing space for storing liquid, the solid housing being disposed with at least one connecting portion;
at least one air bag, the air bag including a deformable bag and an inflatable space; when pressure outside the air bag increasing, the deformable bag shrinking; when pressure outside the air bag decreasing, the deformable bag expanding;
wherein the air bag is positioned in the liquid storing space and the air bag is movable therein.
Referring to
About the solid housing 10, it has a liquid storing space 11 for storing liquid. The solid housing 10 is disposed with at least one connecting portion 12.
With regard to at least one air bag 20. the air bag 20 includes a deformable bag 21 and an inflatable space 22. When the pressure outside the air bag 20 increases, the deformable bag 21 shrinks. When the pressure outside the air bag 20 decreases, said deformable bag expands.
In which, the air bag 20 is positioned in the liquid storing space II and the air bag 20 is movable therein.
As shown in
In the first preferred embodiment as illustrated in
As shown in
Of course, the structure of the present invention can be modified as shown in
Besides, once any air bag 20 is aged or becomes ineffective (such as lack of flexibility), the user can take it out and then replace a new air bag 20. It is very convenient in air bag replacement or maintenance. Of course, the air bag 20 of this invention can be a balloon. Not only it is easy to obtain various balloons, but also the product cost is low. About the design of the solid housing 10, there are many choices. Also, it is possible to use the housing of any existing product or container. Therefore, no matter in manufacturing, assembling, or maintenance, it is very simple and easy.
The advantages and functions of this invention can be summarized as follows.
[1] This invention can be modified from an existing storage tank. Regarding the traditional storage tanks as mentioned above, both of them are required to use specific parts (with certain size and specification) for assembling. It is impossible to arbitrarily select any existing material/object. However, the air bag 20 of this invention can be selected from a common balloon or the like. The solid housing can be used by an existing container or similar product. There is no need to buy extra specific parts/materials.
[2] There is no water leakage problem causing by the membrane of the storage tank. About the traditional storage tanks as mentioned above, both of them have the water leaking problem causing by the membrane. But, the air bag 0 of this design replaces the traditional membrane 972, so that no water leaking problem will occur.
[3] It is easy to replace the air bag. Once the air bag is aged or becomes ineffective, the user can take it out and then replace a new air bag 20 easily.
[4] The overall cost is extremely low. The air bag 20 of this invention can be a common balloon or the like. The solid housing 10 also can be an existing container or similar product. Therefore, no matter in manufacturing, assembling, or maintenance, it is very simple and easy. Also, its overall cost is relatively low.
While this invention has been particularly shown and described with references to the preferred embodiments thereof, it will be understood by those skilled in the art that various changes or modifications can be made therein without departing from the scope of the invention by the appended claims.
