The auxiliary filter unit 150 may be formed to have an inclined surface, and may prevent impurities from entering the filter side while being accumulated on the inclined side.

6 is a diagram illustrating an example of a method of using a filter device according to the present disclosure.

First, as shown in FIG. 6(a), a filter device 100 including a first body 110 and a second body 120, a first container 101 containing contaminated water F1, and a second empty Prepare container 102.

Thereafter, as shown in FIG. 6(b), the first container 101 containing the contaminated water F1 is connected to the first body 110 of the filter device 100, and the second body ( Connect the second container 102 to 120). At this time, the contaminated water F1 of the first container 101 may contain impurities (A; eg, sand, mud, fallen leaves, tree branches, etc.). Impurities A heavier than water may come down to the inlet 211 of the first container 101 by gravity. At this time, impurities A are accumulated on the inclined surface of the auxiliary filter unit 150 protruding toward the first container 101, and impurities do not enter the inlet 151 of the auxiliary filter unit 150, and contaminated water F1 ) Can be entered.

Thereafter, external pressure is applied to the first container 101 containing contaminated water F1 as shown in FIG. 6(c). As for the contaminated water (F1), the water (F2) filtered through the filter device 100 is contained in the second container (102). When external pressure is applied to the first container 101, the liquid F1 containing the impurities A passes through the main filter unit 130 and flows into the second container 102 due to the pressure. By F2), the pressure in the first container 102 is lowered, and the pressure in the second container 102 is increased. At this time, it is important to seal the air and water in the first container 101 and the second container 102 so that they do not escape to the outside. In general, the denser the filter 133 (FIG. 5), the higher the pressure is required.

Thereafter, as shown in FIG. 6(d), when an external pressure is applied to the second container 102 having an increased internal pressure, the air A2 of the second container 102 is passed through the main filter unit 130 to the first container 101. Send to In this way, the air pressure between the first container 101 and the second container 102 is again balanced, or the pressure of the first container 101 is higher than the pressure of the second container 102. As a result, if Figures 6(c) and 6(d) are repeated, contaminated water is passed through the filter material from the first container 101 without external air inflow or a separate pressure control device to facilitate the second container 102. You will be able to send it.

Thereafter, as shown in FIG. 6(e), when the filtered water F2 is sufficiently contained in the second container 102, the pressure to the first container 101 and the second container 102 is stopped. Of course, the filtered water in the second container 102 may be filtered once again through the filter into the first container 101. The filtered water (F2) of the second container 102 may be used as drinking water.

In the present invention, sealing means when pressure is applied to the first container 101 and the second container 120, water and/or air is transferred from the first container 101 to the second container 102 or the second container 102 ) Refers to the degree of sealing that can be moved to the first container 101. For example, when pressure is applied to the first container 101, even if a part of the air in the first container 101 escapes out of the first container 101, the water in the first container 101 passes through the filter. It can be delivered to the second container (102). In addition, when pressure is applied to the second container 101, even if part of the air in the second container 102 escapes out of the second container 102, the air in the second container 101 is removed from the main filter unit 130. It can be delivered to the first container 101 by passing through.
