Description

Technical Field

[0001] The utility model relates to a water treatment machine, in particular to a filter bottle used for the water treatment machine. Background Art

[0002] Most of the filter elements of the existing snap-on filter bottles are disposable filter elements. When the filter element is replaced, the filter element and the bottle body of the filter bottle are replaced together as a whole. The filter element and the bottle body are replaced together as a whole. Since the filter element does not need to be taken out of the bottle body, the cross-sectional area (aperture) of the passage of the connecting part of the clamping joint of the bottle body of the filter bottle and the bottle cap of the filter bottle can be as small as possible, so that the interaction force between the clamping joint of the bottle body of the filter bottle and the clamping structure of the bottle cap of the filter bottle that bear a certain water pressure is smaller and easy to disassemble. However, when the filter bottle is configured so that its filter element can be replaced alone, the clamping joint of the bottle body of the filter bottle cannot be configured to have a small cross-sectional area, and the aperture of the opening of the bottle body of the filter bottle (the cross-sectional area of ​​the passage of the connecting part between the bottle body of the filter bottle and the bottle cap of the filter bottle) is relatively large. For example, the diameter of the opening of the clamping joint of the bottle body where the filter element and the bottle body are replaced together as a whole is generally 5-30 mm, and the diameter of the opening of the bottle body where the filter element is replaced alone is generally 80-160 mm. Under the same water pressure, the interaction force between the bottle body and the bottle cap of the two different filter bottles is quite different. The interaction force between the bottle body and the bottle cap of the filter bottle in which the filter element is replaced alone is much greater than the interaction force between the clamping joint of the bottle body and the bottle cap of the filter bottle in which the filter element and the bottle body are replaced as a whole. Since the interaction force between the bottle body and the bottle cap of the filter bottle in which the filter element is replaced alone is relatively large, the two are usually fixed by a threaded connection, but the filter element of the threaded filter bottle is not easy to disassemble and replace. Utility Model Content

[0003] The main advantage of the utility model is to provide a filter bottle, in which the interaction force between the bottle body and the bottle cap of the filter bottle of the utility model is dispersed, so that the bottle body and the bottle cap of the filter bottle of the utility model can be fixed by a snap-on manner, so that the bottle body is easy to disassemble and the filter element can be replaced separately.

[0004] Another advantage of the present invention is that it provides a filter bottle, wherein a sealing ring is arranged between the filter bottles of the present invention, and the sealing ring is specially designed to have a good sealing effect.

[0033] As shown in the attached picture Figures 1 to 8According to the filter bottle of the utility model embodiment, the first engagement blocks 131 of the first engagement unit 13 are spaced apart from each other and horizontally extend along the outer side 121 of the end 12 of the bottle body 10, the second engagement blocks 132 are spaced apart from each other and horizontally extend along the outer side 121 of the end 12 of the bottle body 10, the first engagement protrusions 231 are spaced apart from each other and horizontally extend along the inner side 221 of the side wall 22 of the bottle cap 20, and the second engagement protrusions 232 are spaced apart from each other and horizontally extend along the inner side 221 of the side wall 22 of the bottle cap 20. The inner side 221, wherein the length L1 of the first engaging block 131 is smaller than the distance S1 between each two adjacent first engaging protrusions 231, and the length L2 of the second engaging block 132 is smaller than the distance S2 between each two adjacent second engaging protrusions 232, so that when the bottle cap 20 is clamped to the bottle body 10 or the bottle cap 20 is unclamped from the bottle body 10, the first engaging block 131 can pass between two adjacent first engaging protrusions 231, and the second engaging block 132 can pass between two adjacent second engaging protrusions 232.

[0034] As shown in the attached picture Figures 1 to 8According to the embodiment of the utility model, the second engaging block 132 of the first engaging unit 13 of the filter bottle extends outward from the outer side 121 of the end 12 of the bottle body 10, and the inner side 221 of the side wall 22 of the bottle cap 20 forms a group of second engaging grooves 220, wherein the second engaging grooves 220 are configured to be adapted to match the second engaging blocks 132, and the second engaging grooves 220 are respectively formed above the second engaging protrusions 232, so that the second engaging blocks 132 can be engaged with the second engaging grooves 220. It can be understood that when the second engaging block 132 extends outward from the outer side 121 of the end portion 12 of the bottle body 10, the circumference d1 of the first engaging block 131 is smaller than the circumference D1 of the second engaging block 132, the circumference d1 of the first engaging block 131 is smaller than the circumference D2 of the second engaging protrusion 232, and the circumference D1 of the second engaging block 132 is larger than the circumference D2 of the second engaging protrusion 232, so that when the bottle cap 20 is clamped to the bottle body 10 or the bottle cap 20 is unclamped from the bottle body 10, the first engaging block 131 can pass through the second engaging protrusion 232.
