In a particular embodiment, cistern 11 can according to circumstances further comprise storage 15, it can use any suitable method to be held or be fixing, and be applicable to and store some tealeaves or draft fragrant plant, or be applicable to that immersion is to prepare draft aromatic drink, soak when needed or only to be tea.

Filter further comprises filter 13, and it can be any filter or filter cylinder that manufacturer sells.Fig. 1 b is depicted as the purposes of cylindrical filter.

Filter further comprises filter support 12, and it is used for supporting cistern 11 and filter 13; And the structural detail 14 of the shape of suitable bottle base member 1.

In the embodiment shown in Fig. 1 b, structural detail 14 is columniform, and top cover has the hole, can provide passage and support for cistern 11; Two walls are respectively inwall 19 and outer wall 20, define a cylindrical channel, and when tilting with convenient bottle, the water after the processing can upwards flow.

When using filter support 12 that cistern 11 and filter 13 are placed in the appropriate location, filter support 12 and structural detail 14 cooperate to define cistern or middle volume 16 as shown in Figure 2, thereby when bottle tilted to the left, cistern or middle volume 16 obtained the water that flows through opening 18 from cistern 11.

For reaching this purpose, filter support 12 has the circle of the cross section that is suitable for structural detail 14, to constitute sealed volume.Preferably, the surface of filter support 12 is suitable for the cross section of the cylinder that the inwall by structural detail 14 constitutes.For example tightening members such as the protuberance on the structural detail 14 or groove (not showing in the accompanying drawing) can remain on the appropriate location with filter support 12.

In addition, filter support 12 has and is generally columniform two holes, is applicable to respectively and takes in cistern 11 and filter 13, and make the two firmly be in the appropriate location, as shown in Figure 2, guarantees that simultaneously the middle volume 16 that will define seals.

Can use and for example press down or be fastened to filter support 12 with some kinds of methods such as screw thread are fixing to guarantee cistern 11 and filter 13.

According to circumstances, for improving the stability of cistern 11, also can use any suitable method that cistern 11 is fastened to structural detail 14.

As mentioned before, filter 13 is fastened to the filter support 12 with the opening that is suitable for this filter.Therefore, can transform filter easily by mode such as for example unscrew.

Can find out that in addition device takes into account this favorable factor of modularity, because can provide some kinds of filter support 12 to adapt to existing some kinds of different filter model on the market like this.

As mentioned above, filter support 12 has important and very favourable function, namely as shown in Figure 2, can define the middle volume 16 that the outer surface by the inwall 19 of the top of filter 13, structural detail 14 and cistern 11 constitutes.

Volume 16 can first retaining in the middle of this that defines when above-mentioned various element herein is set, and then immediately water is handled by filter 13, but remaining water does not then add and handles and be retained in the cistern in the cistern 11.

Therefore can find out, the present invention relates to use foolproof method and use minimum internal part to make filtration system, can begin or stop filter process by this foolproof mode of (or right side) inclination bottle to the left in the described system, thereby water is flowed upward in the middle retaining volume 16 from cistern 11, or make water stop to flow.

Therefore, filter support 12 has been guaranteed three differences and ten minutes appropriate functional:

-cistern 11 is kept in position, that is, remain in the top of bottle, as shown in Figure 2;

-filter 13 is kept in position, that is, remain in the top of bottle equally and handle the water of accumulating in the internal capacity 16;

-volume 16 in the middle of defining, it is used for accumulating the flowing water by the upper left side opening 18 of cistern 11.

Therefore, this layout is very favourable, can prevent when bottle is shifted that filter 13 is stuck in the water.This filters water between arranging and also guaranteeing in due course, is chosen in usually to be about to before the use water be filtered.

In a particular embodiment, filter support 12 for example can be fastened to the different precalculated positions of structural detail by one group of predetermined groove, thereby adjusts according to the amount of the filtered water of the bottom that is accumulated in element 1.

In a particular embodiment, the number system that filter support 12 or structural detail 14 comprise for the access times that calculate filter and therefore be convenient to filter is managed ... with the simplest form, can provide the vision hierarchy system to realize distinguishing date of using for the first time filter.

For the purpose of clear, each stream in the process of the filtering flask shown in Figure 2 of explanation use now.

Fig. 3 a is depicted as the user and uses water to be filtered to fill cistern 11.If directly use, then can fill volume 11 and 16 fully, so that the amount maximum of handled water.

Otherwise, if portable use then only need be filled volume 11, in order to can distinguish the beginning of filter process.Therefore, can take bottle to place to use, in addition higher and also can so do when being easy to bacterial growth when temperature.

In fact, user's bottle that only need tilt to the left in use shown in Fig. 3 b, so that the partially liq in the cistern 11 flows through opening 18, is accumulated in then in the volume 16, and uses filter 13 to filter in volume 16.

Therefore, Fig. 3 c is depicted as the water stream channel in the filter, and water will be accumulated in the bottom volume 20 of bottle subsequently.

Should note (this also is an interesting advantage of the present invention), " inclination " bottle can stop to filter again to the right, and therefore prevents that water stagnation is in volume 20.

When the user need use filtered water, only need (if the user wants to stop to prepare filtered water) or (if the user will continue to prepare filtered water) inclination bottle to the right to the left, thereby make water along inwall 19 and outer wall 20 these two volume flow that the surface is defined of structural detail 14.

Therefore, filtering flask according to the present invention has very high flexibility, and can " by demand " water be filtered, that is, protect filtered water not to be subjected to the influence of bacterial growth in use.

Otherwise the water that removes dechlorination is directly filtered and store to known devices to water, thereby can help bacterial multiplication.

Fig. 4 a to Fig. 4 d is depicted as the utilization of filter in preparation tea or certain soak process.As shown in the figure, at first tealeaves or immersion plant are placed inundator 15, then cistern 11 is filled water.The bottle that tilts to the left can move the water to flow in the volume 16 and then use filter 13 to filter in volume 16.Purify waste water accumulate the bottom of volume 20 after, but therefore just those tealeaves in the submergence inundator.

Usually, the main part of bottle can be made by transparent plastic material, purifies waste water directly to see, and stop the preparation of water when the water yield is enough.

One embodiment of the present invention is illustrated in conjunction with the bottle of portable use.Obviously, this is limiting examples, because affiliated field those skilled in the art can transform the present invention making any other container, even can make and earlier water be filtered and then heat the kettle that uses for directly.

The present invention can be used for making any container usually, as beverage bottle, flask, kettle etc.

Similarly, described embodiment shows that filter operation is by this behavior control of bottle of tilting to the left.Can adjust this configuration easily, and the opening 18 of cistern 11 can be arranged in the right side, thereby when tilting bottle to the right, can make water in the cistern 11 be subjected to the gravity effect and flow.
