Best Mode for Carrying Out the Invention Reference will now be made in detail to the preferred embodiments of the present invention.
In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, it is noted that a basic concept of the present invention is to allow a user to selectively use original water or purified water in the form of shower water or foaming water by installing a filter member for filtering original water in a head apparatus.
Hereinafter, a preferred embodiment of a head apparatus for an aqueduct capable of purifying water and having the above basic concept will be described with reference to accompanying drawings.
FIG. 1 is an exploded perspective view showing a multi-functional head apparatus for an aqueduct capable of purifying water according to one embodiment of the present invention, and FIG. 2 is a partially sectional view showing the multifunctional head apparatus according to one embodiment of the present invention. As shown in FIGS. 1 and 2, the multi-functional head apparatus of the present invention includes a handle member 200, a water path switching unit 400 or 800, a head member 500, and a water-status switching unit 600 or 700.
The handle member 200 is connected to the aqueduct and provided at an inner portion thereof with a filter housing 220 having a water purifying filter 210 in such a manner that the filter housing 220 does not make contact with an inner wall of the handle member 200.
The water purifying filter 210 includes a filter capable of forming magnetized water, which is good for the health.
The handle member 200 is provided at one end thereof with a fixing screw part, which is detachably coupled to the aqueduct through a sealing member 230, and at an inner peripheral portion of the other end thereof with a coupling screw part 200b, which is detachably coupled to a screw 440a of a connection member 440, which will be described later, through sealing members 301 and 302.
In addition, the handle member 200 is formed at an outer peripheral portion thereof with an anti-sliding part 200c including a plurality of slots.
One end of the filter housing 220 accommodated in the handle member 200 is closed in vicinity of the fixing screw part 200a of the handle member 200.

The core member is sequentially formed at an outer surface thereof with an inner non-woven fabric layer, an absorption layer and an outer non-woven fabric layer.
The water path switching unit 400, as shown in FIGS. 1 and 3, includes the connection member 440, a coupling member 410, a rotating member 420, a fixing member 430 and a fixing shaft member 450.
The connection member 440 has a cylindrical pipe shape and the screw 440a, which is screw-coupled with the coupling screw part 200b of the handle member 200, is formed at one end of the connection member 440. In addition, a coupling screw 440b, which is screw-coupled with a coupling piece 412 of the coupling member 410 is formed at an inner portion of the other end of the connection member 440.

The screw section 412a of the coupling piece 412 is screw-coupled to the coupling screw 440b of the connection member 440 by interposing a sealing ring 410a. In addition, the protrusions 413 and 414 are protruded from an inner peripheral portion of the coupling member 410 so as to selectively exhaust original water or purified water.
The protrusion 413 is vertically protruded from a center of the inner peripheral portion of the coupling piece 412 and bent in parallel to the coupling piece 412 so that a guide hole 413b is formed between the protrusion 413 and the hole 41 Id. Accordingly, purified water introduced into the coupling member 410 is exhausted out of the coupling member 410 through the guide hole 413b and the hole 41 Id.
In addition, the protrusion 414 is parallel protruded from the inner peripheral portion of the body plate 411 while being spaced from the coupling piece 412, so original water introduced between the coupling piece 412 and the protrusion 414 is exhausted to the exterior through the original water exhaust hole 41 le.

A concave-convex section 424b is formed at an outer peripheral surface of the cylindrical rim 424 of the rotating member 420 so as to allow the user to easily rotate the cylindrical rim 424.
In addition, a protrusion 424a is formed at a predetermined portion of the concave-convex section 424b. The protrusion 424a corresponds to a basis protrusion
500b formed on the head member in order to represent an exhaust of original water or purified water, so the protrusion 424a rotates about the basis protrusion 500b as the rotating member 420 rotates, thereby, representing the present status of selected water.
Thus, the basis protrusion 500b of the head member 500 and the protrusion
424a of the rotating member 420 may form an indicating device for representing the preset status of selected water. However, according to another embodiment of the present invention, it is also possible to represent the exhaust of original water or purified water by utilizing a predetermined color.
The fixing member 430 is inserted into a lower portion of the cylindrical rim 424 of the rotating member 420.
The fixing member 430 includes a disc plate 433 inserted into the cylindrical rim 424 of the rotating member 420 and formed at a predetermined portion thereof with water outlet holes 433d and 433e, which are selectively communicated with the communication hole 423d, and a fixing part 434 integrally formed with a lower surface of the disc plate 433 in such a manner that the water outlet holes 433d and 433e are positioned within the fixing part 434 and formed at an outer wall thereof with a fixing screw section 434a, which is screw-coupled with a screw part 500a of the head member 500.
Herein, the fixing screw section 434a of the fixing part 434 is screwOcoupled with the screw part 500a of the head member 500 by interposing a sealing ring 435 therebetween.

The water position determining holes 433b and 433c are formed in the fixing member 430 corresponding to the embossing parts 423b and 423c of the partition plate 423.
In addition, holes 41 Id and 41 le of the coupling member 410 are alternately communicated with the water outlet holes 433d and 433e of the fixing member 430. The fixing shaft member 450 extends through a perforated hole 411a of the coupling member 410, a connection hole 423a of the connection member 420 and a coupling hole 433a of the fixing member 430, thereby integrally coupling the coupling member 410, the connection member 420 and the fixing member 430 with each other.
The fixing shaft member 450 includes a boss 451 locked with the coupling member 410, a shaft 452d protruded from the boss 451 and sequentially passing through the coupling member 410, the connection member 420 and the fixing member 430, and a coupling piece 453 coupled to an end of the shaft 452 so as to fixedly maintain the coupling member 410, the com ection member 420 and the fixing member 430.

In addition, a mesh 762 is provided between the adjusting member 750 and the fixing cap 760 in order to generate foaming water.
Hereinafter, an operation of the multi-functional head apparatus having the above structure will be described.
If the user wants to use original water, the user securely fixes the head apparatus 100 to the aqueduct. In this state, as shown in FIGS. 1 to 3 and 5, the user rotates the rotating member 420 in one direction so as to rotate the protrusion 424a of the rotating member 420 at a right angle with respect to the basis protrusion 500b of the head member 500.
Thus, embossing parts 423b and 423c formed in the rotating member 420 are released from the water position determining holes 411b and 411c of the coupling member 410 and water position determining holes 433b and 433c of the fixing member 430. The embossing parts 423b and 423c are again inserted into the water position determining holes 411b and 411c of the coupling member 410 and water position determining holes 433b and 433c of the fixing member 430 after being rotated at a right angle. In addition, the communication hole 423d formed in the partition plate 423 of the rotating member 420 is communicated with the original water exhaust hole 41 le of the coupling member 410 and the original water outlet hole 433 e of the fixing member 430.
Accordingly, water supplied from the aqueduct is introduced into the original water exhaust hole 41 le of the coupling member 410 while flowing between the handle member 200 and the filter housing 220. Then, water is introduced into the head member 500 by way of the communication hole 423d of the rotating member 420 and the original water outlet hole 433 e of the fixing member 430.
In addition, when the protrusion 424a matches with the basis protrusion 500b of the head member 500 by reversely rotating the rotating member 420 as shown in FIG. 6, the original water exhaust hole 41 le of the coupling member 410 and the original water outlet hole 433e of the fixing member 430 are closed, so that the communication hole 423 d of the rotating member 420 matches with the purified water exhaust hole 41 Id of the coupling member 410 and the purified water outlet hole 433d of the fixing member 430. Accordingly, original water supplied from the aqueduct is introduced into the inlet holes 220a of the filter housing 220. At this time, original water is purified while passing through the purifying filter 210 accommodated in the filter housing 220 and is exhausted to the exterior through the outlet holes 220b of the filter housing 220. Exhausted purified water is introduced into the purified water exhaust hole 422d of the coupling member 410 and introduced in to the head member 500 through the communication hole 423d of the rotating member 420 and the purified water outlet holes 433d of the fixing member 430.
In this state, even if the protrusion 424a further rotates at 180° with respect to the basis protrusion 500b of the head member 500 by rotating the rotating member 420 in a forward direction, other than the reverse direction, purified water may be supplied.
In addition, as shown in FIG. 13, if it is required to use originally water by connecting the head apparatus 100 equipped with the water path switching unit 800 to the aqueduct, the user pushes the button member 811c, which is outwardly protruded from the head member 500.
Accordingly, the adjusting bar 811 is pushed by the button member 811c, so that the cap member 850 and the connection bar 870 accommodated in the purified water receiving column 833, and the cap member 860 aligned in the original water receiving column 834 are integrally moved. In addition, the adjusting bar 812 connected to the cap member provided in the original water receiving column 834 is protruded out of the head member 500 together with the button member 812c.
At this time, the ball members 843 and 844 accommodated in the cap members 850 and 860 close the purified water outlet hole 831a and open the original water outlet hole 831b in response to the operation of the ball members 843 and 844. The opening/closing operation of the ball members 843 and 844 may be elastically carried out by means of elastic force of compression springs 845.
Therefore, water supplied from the aqueduct is introduced into the handle member 200. Then, water is introduced into the communication hole 821c of the connection member 820 while flowing between the handle member 200 and the filter housing 220. After that, water is supplied to the head member 500 through the original water receiving column 834 and the original water outlet hole 831b, which are communicated with the communication hole 821c of the connection member 820.
When it is required to use purified water, as shown in FIG. 14, the user pushes the button member 812c outwardly protruded from the head member 500. In this case, the water path switching unit 800 is operated in the reverse order as compared with the operating order for exhausting original water as described above, so the purified water outlet hole 831a is opened and purified water is exhausted.
In addition, if the user wants to use original water or purified water as foaming water, as shown in FIG. 5, the user rotates the exhaust water adjusting member 620 of the water-status switching unit 600 in one direction in such a manner that the exhaust water adjusting member 620 upwardly moves along the guide slot 611c of the fixing member 610.
Because of the upward movement of the exhaust water adjusting member 620, the opening/closing member 630 opens the foaming water hole 623a of the exhaust water adjusting member 620, and the foaming water column part 623 makes surface- contact with an underside of the fixing member 610. Accordingly, the exhaust holes 611b of the fixing member 610 are accommodated in the foaming water column part 623, so that a water path between the exhaust holes 611b and the shower water hole 625 a is shut off. Accordingly, purified water or original water supplied into the head member
500 passes through the foaming water hole 623a and the mesh 651 installed in the foaming water hole 623a, so foaming water is supplied.
Then, as shown in FIG. 6, the exhaust water adjusting member 620 is reversely rotated in such a manner that the exhaust water adjusting member 620 moves down along the guide slot 611 c of the fixing member 610.
Due to the downward movement of the exhaust water adjusting member 620, the foaming water hole 623a is closed by means of the opening/closing member 630 and the exhaust hole 61 lb of the fixing member 610 is communicated with the shower water hole 625 a of the exhaust water adjusting member 620, so that shower water is supplied. In addition, when supplying foaming water by using the water-status switching unit 700 as shown in FIGS. 7 to 9, the user rotates the adjusting member 750 in one direction, so the rotating member 730 is rotated together with the adjusting member 750. In addition, when the locking protrusions 73 Id of the rotating member 730 make contact with first ends of locking protrusions 712 of the fixing member 710, the rotation of the rotating member 730 stops .
As the rotating member 730 rotates, the foaming water hole 731a of the rotating member 730 matches with the perforated hole 711a of the fixing member 710, so original water or purified water supplied into the head member 500 sequentially passes through the perforated holes 711a of the fixing member 710, the foaming water holes 73 la of the rotating member 730, and the mesh 762 installed in the foaming water holes 731a, so that foaming water is supplied.
In addition, when the adjusting member 750 is rotated in a reverse direction, the rotating member 730 is rotated together with the adjusting member 750, so the locking protrusions 73 Id are locked with second ends of the locking protrusions 712 of the fixing member 710.
When the rotating member 730 has been reversely rotated, the shower water holes 731b of the rotating member 730 match with the perforated holes 711a of the fixing member 710, so original water or purified water supplied into the head member 500 passes through the perforated holes 711a of the fixing member 710, the shower water holes 731b of the rotating member 730, and the shower water hole 731c, so that original water or purified water is exhausted as shower water through the shower water exhaust hole 740b of the coupling member 740 and the elongated holes 750c of the adjusting member 750.
