Detailed Description

In an embodiment, please refer to fig. 1-5, the filter of the present invention comprises a body and a filter element 3, wherein the body is provided with a water inlet 51 and a purified water outlet 52; the anti-freezing shell comprises a body and is characterized by further comprising a deformable anti-freezing shell 2, wherein the anti-freezing shell 2 is arranged in the body, and a hollow layer for providing a deformation space for the anti-freezing shell 2 is arranged between the anti-freezing shell 2 and the body; the filter element 3 divides the inner cavity of the anti-freezing shell 2 into a raw water cavity 10 and a purified water cavity 20, wherein the raw water cavity 10 is communicated with the water inlet 51, and the purified water cavity 20 is communicated with the purified water outlet 52.

In this embodiment, the outer surface of the anti-freezing shell 2 is provided with a plurality of protrusions distributed in a scattered manner. A gap is reserved between the convex part and the body, and the convex part is a small convex rib 21.

In this embodiment, the body includes one end open-ended shell 1 and is equipped with water inlet 51, water purification export 52

's end cover

5, 2 one end openings of anti-freezing shell, just anti-freezing shell 2 is located shell 1, and end cover 5 sets up in shell 1's open-ended one end department to with the butt joint of 2 open-ended one ends of anti-freezing shell. Specifically, end cover 5 with shell 1 sealing connection, the open-ended one end of anti-freezing shell 2 with the cooperation has first sealing washer 8 between the shell 1 medial surface.

In this embodiment, as shown in fig. 3, the hollow layer includes a first hollow layer 6 formed between the inner side surface of the outer shell 1 and the outer side surface of the anti-freezing shell 2, and a second hollow layer 7 formed between one end of the outer shell 1 departing from the end cover 5 and one end of the anti-freezing shell 2 departing from the end cover 5, where the first hollow layer 6 is communicated with the second hollow layer 7. Thus, when the anti-freeze shell 2 is deformed, the side wall portion is deformed in the direction of the first hollow layer 6, and the bottom wall portion (i.e. the end portion facing away from the end cap 5) is deformed in the direction of the second hollow layer 7, as shown in fig. 3, where the arrows indicate the deformation direction of the anti-freeze shell 2. And part of the small convex ribs 21 on the outer surface of the anti-freezing shell 2 are distributed on the outer side surface of the side wall part of the anti-freezing shell 2, and the rest are distributed on the outer surface of the bottom wall part of the anti-freezing shell 2. In other embodiments, the hollow layer comprises a first hollow layer formed between the outer shell inner side and the freeze shell outer side.

In this embodiment, a supporting seat 4 capable of passing water is disposed between the filter element 3 and the end cap 5, and the supporting seat 4 supports against the filter element 3. Specifically, the filter core 3 moves towards the one end of end cover 5 with supporting seat 4 sealing connection, supporting seat 4 with the cooperation is cup jointed to filter core 3, and the cooperation has second sealing washer 9 between the two.

In this embodiment, the filter element 3 is cylindrical, and the raw water cavity 10 is located at the periphery of the purified water cavity 20. In other embodiments, the filter direction of the filter element is reversed, and the water purifying cavity is positioned at the periphery of the raw water cavity.

In this embodiment, the anti-freezing shell 2 is made of an elastic material (e.g., silica gel), and has good low temperature resistance, flexibility and ductility.

The utility model discloses a filter, during operation, water gets into former water cavity 10 from water inlet 51, gets into in the water purification chamber 20 after filter by filter element 3, then flows out by water purification export 52, as shown in FIG. 4, the arrow indicates the rivers direction in the picture. Since the density of water is about 1000 kilograms per cubic meter and the density of ice is about 900 kilograms per cubic meter, the volume increases by 111% when the water condenses into ice. At this time, the volume change of the ice cubes brings the anti-freezing shell 2 to expand towards the hollow layers (including the first hollow layer 6 and the second hollow layer 7), as shown in fig. 5, the arrow in the figure indicates the deformation direction of the anti-freezing shell 2, and the deformation state of the anti-freezing shell 2 is not shown in fig. 5. Since the volume of the hollow layer is increased more than the volume increase of water to ice, the ice pieces will stop expanding in the hollow layer, eliminating the risk of the casing 1 being burst.

The utility model discloses a filter can utilize the hollow layer provides the deformation space for preventing frostbite shell 2 when water freezes and arouses the volume change to the protection filter avoids water to freeze the volume expansion and props up broken body. And, the utility model discloses an among placing filter core 3 in the shell 2 that prevents frostbite in not, the installation is more simple and convenient, does not have the problem that drops. Specially, prevent frostbite shell 2 and shell 1 and constitute double-deck shell structure, the ability of bearing pressure is better, makes the utility model discloses a frostproofing effect is better.

The above embodiments are only used to further illustrate the filter of the present invention, but the present invention is not limited to the embodiments, and any simple modification, equivalent change and modification made by the technical entity of the present invention to the above embodiments all fall into the protection scope of the technical solution of the present invention.
