Abstract

A purification device comprises a main body having an open extending horizontally; a rotator in the opening to be rotatably mounted on the main body; and a manipulation structure spaced from and above the rotator and rotatably connected to a top face of the main body, the manipulation structure protruding forward of the main body. The device also includes a water-outlet module with a fixed cover fixed to the rotator through the opening, the fixed cover protruding forward of the main body, and a top of the fixed cover being connected to a bottom of the manipulation structure; a vertically-movable cover held in contact with the fixed cover; and a water-outlet nozzle mounted onto a bottom of the vertically-movable cover. When the vertically-movable cover rises to a highest level, a top of the vertically-movable cover is located in a space between the rotator and the manipulation structure.

First claim

What is claimed is:

1. A device comprising:
a main body having a front face that includes an opening;
a rotator provided in the opening to be rotatably mounted on the main body and to rotate horizontally in the opening;
a handle provided above and spaced apart from the rotator and rotatably connected at a top face of the main body, wherein at least a portion of the handle protrudes forward of the opening of the main body; and
an outlet including:
a first cover fixed to the rotator through the opening, wherein the first cover protrudes forward of the main body, and a top of the first cover is connected to a bottom of the handle;
a second cover that is vertically movable while being held in contact with the first cover; and
an outlet nozzle mounted at a bottom of the second cover,

wherein when the second cover rises to a highest level, a top of the second cover is located between the rotator and the handle,
wherein a first space is defined in the first cover, and
wherein the second cover is received in the first space in the first cover and moves vertically in the first space to vary a vertical level of the outlet nozzle.

2. The device of claim 1 , wherein at least one of the first cover or the second cover includes at least one resisting protrusion, and wherein the resisting protrusion is configured to reduce a vertically moving force applied to the second cover for vertical movement of the second cover.

3. The device of claim 2 , wherein the at least one resisting protrusion protrudes outward from a face of the second cover facing the first cover and extends in a vertical direction to linearly contact the first cover.

4. The device of claim 2 , wherein the at least one resisting protrusion protrudes outward from a face of the first cover facing the second cover and extends in a vertical direction to linearly contact the second cover.

5. The device of claim 1 , wherein the first cover and the second cover are made of different materials.

6. The device of claim 5 , wherein one of the first cover or the second cover is made of one of acrylonitrile-butadiene-styrene (ABS) resin or polyoxymethylene (POM), and wherein the other of the first cover or the second cover is made of other one of acrylonitrile-butadiene-styrene (ABS) resin or polyoxymethylene (POM).

7. The device of claim 1 , wherein at least one of the first cover or the second cover includes a guide configured to control a movement of the second cover such that the second cover moves vertically in a straight line.

8. The device of claim 7 , wherein the second cover has at least one of a first guide groove recessed inwardly therein or a first guide protrusion protruding outwardly therefrom,
wherein the first cover has at least one of a second guide protrusion inserted into the first guide groove or a second guide groove accommodating the first guide protrusion, and
wherein each of the first and second guide grooves and protrusions extends in a vertical direction.

9. The device of claim 8 , wherein the second cover has a guide bracket having the first guide groove or the first guide protrusion.

10. The device of claim 9 , wherein the second guide groove of the first cover receives therein the first guide protrusion of the guide bracket and an end of the second cover.

11. The device of claim 1 , wherein at least one of the first cover or the second cover has a stopping mechanism configured to block further descent of the second cover when the second cover reaches a lowest level.

12. The device of claim 11 , wherein the stopping mechanism includes:
a stopping protrusion protruding outward from the top of the second cover; and
a stopping groove defined inwardly in a bottom of the first cover to receive the stopping protrusion.

13. The device of claim 12 , wherein the stopping protrusion is formed along a perimeter of the second cover, or the stopping groove is formed along a perimeter of the first cover.

14. The device of claim 1 , wherein the second cover has at least one of:
a flange protruding outwardly from the bottom of the second cover to contact a bottom of the first cover when the second cover rises to the highest level, or
at least one outwardly projecting handle formed on an outer surface of the second cover, the outwardly projecting handle including a shoulder that contacts a seat groove formed on a side of the first cover when the second cover rises to the highest level.

15. The device of claim 1 , wherein the handle is configured to rotate together with the outlet upon rotation of the outlet.

16. The device of claim 15 , wherein a rotation hole is defined in a top face of the main body, and wherein the handle is configured to rotate along an inner circumference of the rotation hole.

17. The device of claim 16 , wherein an edge of the main body defining the rotation hole has a vertical portion extending downward and a horizontal portion extending inward from a bottom of the vertical portion.

18. The device of claim 17 , wherein the device further comprises:
a rotatable bracket secured to the handle, wherein the rotatable bracket rotates along the horizontal portion while bearing against a top and a bottom of the horizontal portion.

19. The device of claim 18 , wherein the rotatable bracket has a rotation guide rib protruding outward from a face of the rotatable bracket facing at least one of the horizontal portion or the vertical portion, and wherein the rotatable bracket linearly contacts the horizontal portion or the vertical portion via the rib.
