Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

Generally speaking, when the water storage tank has a micro-leakage and is in a negative pressure state, the conventional respirator cannot timely supplement air into the water storage tank, which easily causes pollutants to enter the water storage tank, thereby polluting purified water in the water storage tank. In addition, traditional respirator is easily drenched when water vapor is more in the water storage tank internal environment to lead to reducing the filter core permeability of respirator, and breed the bacterium, generally need dispose the electrical heating cover and continuously heat the respirator, make the filter core of respirator keep dry, in order to guarantee the filter core permeability, will make the device structure complicated like this, increase cost.

Based on this, referring to fig. 1 and fig. 2, fig. 1 shows a view structural diagram of a purified water storage device according to an embodiment of the present invention, and fig. 2 shows another view structural diagram of a purified water storage device according to an embodiment of the present invention. An embodiment of the utility model provides a pair of active breathing subassembly, active breathing subassembly include air cleaner 10, fan 20, first pipeline 30 and second pipeline 40. The air filter 10 has an inlet end 11 and an outlet end 12. The air outlet side of the fan 20 is in communication with the air inlet end 11, and the fan 20 is used to blow air into the air filter 10. One end of the first pipeline 30 and one end of the second pipeline 40 are both communicated with the air outlet end 12, and the other end of the first pipeline 30 is used for being communicated with the storage tank 50. The other end of the second pipe 40 is provided with an opening degree adjusting valve 60.

After the active respiration component is installed on the storage tank 50, air is blown into the air filter 10 through the fan 20, after the air is filtered by the air filter 10, a part of the filtered clean air is conveyed into the storage tank 50 through the first pipeline 30, so that the storage tank 50 can be always in a positive pressure state, the air in the storage tank 50 can be blown out to be discharged outwards through the first pipeline 30, the air outlet end 12 of the air filter 10 and the second pipeline 40, the effect of replacing the air in the storage tank 50 is achieved, and the cleanliness of the air in the storage tank 50 can be ensured; another part of the filtered clean gas passes through the second pipe 40 and is discharged to the outside through the opening degree adjusting valve 60. So, no matter when storage tank 50 changes because of getting into or the emergence pressure differential of discharge purification water, because first pipeline 30 can let in the clean gas all the time and maintain the interior pressure-fired state of storage tank 50 in the storage tank 50, just can make and be full of clean gas in the storage tank 50, even storage tank 50 has the leakproofness problem simultaneously, also can avoid external environment's air to enter into storage tank 50, can reduce the pollution risk of purification water, guarantee the cleanliness factor of purification water. In addition, since the blower 20 continuously blows air into the air cleaner 10, it is possible to prevent moisture inside the storage tank 50 from entering the air cleaner 10 as much as possible, thereby ensuring filtering performance of the air cleaner 10, and it is possible to relatively simplify the structure of the apparatus without adding a heating device for heating operation.

The first pipeline 30 and the second pipeline 40 are specifically stainless steel pipes, so that the cleanliness of the first pipeline 30 and the second pipeline 40 is high, and the purified water in the storage tank 50 can be prevented from being polluted due to bacteria breeding as much as possible. The first duct 30 and the second duct 40 may be ducts made of other materials, and are not limited herein.
