A locking protrusion piece 2343 is formed to press the 2350 and to engage the cover plate 2350 by the locking jaw protruding inward.

In addition, a solid vitamin preparation 2360 may be disposed inside the stumbling block 2343 . The solid vitamin preparation 2360 removes chlorine remaining in the second water moving from the body case 200 to the head unit 300 . Chlorine is known as a substance that causes skin aging or various skin troubles by reacting with and destroying skin proteins constituting the skin of the human body. The solid vitamin preparation 2360 removes chlorine through a chemical reaction with chlorine. The solid vitamin preparation 2360 according to an embodiment may be water-soluble vitamin C. Vitamin C neutralizes the chlorine remaining in the secondary water and changes it into a weak acid that is good for the skin. Through this, 99.9% of residual chlorine can be removed. The solid vitamin preparation 2360 adds a vitamin component to the second water while the second water flows out of the second filter module 2300 .

The cover plate 2350 prevents the solid vitamin preparation 2360 from being separated from the stumbling block 2343 . When the cover plate 2350 is mounted, the solid vitamin preparation 2360 is exposed between the stumbling blocks 2343.

The fastening protrusion 323 and the pressing fixing protrusion 324 are arranged in an annular spaced apart from the annular rear flow path part 322 . In addition, a connection protrusion 325 for reinforcing rigidity against an impact applied to the lower ends of the fastening protrusion 323 and the pressing fixing protrusion 324 is formed in the annular rear channel portion 322 . At this time, the connecting protrusion 325 may be formed to have the same curvature as the annular rear channel portion 322 . The pressing fixing protrusion 324 prevents the fine particle generating member 400 from being separated and separated from the state inserted and disposed in the vortex generating chamber protrusion 314 , which will be described later. To this end, the pressing fixing protrusion 324 may press the inlet body 410 of the fine particle generating member 400 vertically downward in a state in which the front cover 310 and the rear cover 320 are assembled and fastened.

In addition, the head part 300 protrudes backward from the lower surface of the rear cover 320 and is fastened to the body part 210, and a locking sleeve 330 in which an inner space into which the second filter module 2300 is inserted and coupled is formed. may further include.

At this time, on the outer peripheral surface of the locking sleeve 330, a second locking part 331 for allowing the head part 300 to be engaged with or separated from the body case 200 by either clockwise or counterclockwise rotation is formed. can

On the other hand, the front cover 310 has a linear front flow path part 311 that is symmetrically branched in both directions by 180 degrees, and a second water at each end of the linear front flow path part 311 is bifurcated and circulated in a circle. It may include an annular front flow path part 312 . At this time, the linear front flow path part 311 and the linear rear flow path part 321 are disposed to face each other. In addition, the annular front channel portion 312 and the annular rear channel portion 322 are disposed to face each other.

The fastening protrusion 313 and the vortex generating chamber protrusion 314 are annularly spaced apart from the annular front flow path part 312 . Specifically, a plurality of vortex generating chamber protrusions 314 in which the vortex generating protrusions 420 are accommodated may be disposed on the inner surface of the annular front flow path part 312 to be spaced apart from each other. In addition, the connection protrusion 315 for reinforcing rigidity against an impact applied to the lower ends of the fastening protrusion 313 and the vortex generating chamber protrusion 314 is formed in the annular front flow path part 312 . At this time, the connecting protrusion 315 may be formed to have the same curvature as the annular front flow path portion 312 .

In addition, the head part 300 may further include a fine particle generating member 400 . The fine particle generating member 400 is formed to protrude vertically upward from the center of the inlet body 410 and the inlet body 410 in which the incision inlet groove 412 through which the second water is introduced is formed, and at least one guide groove ( 421) and may include an arc-shaped connection part 430 connecting between the vortex generating protrusion 420 and the inlet body 410.

The inlet body 410 may further include a guide cutting part 411 formed by cutting a portion of the side of the inlet body 410 . In this case, the inlet body 410 may be formed symmetrically or asymmetrically according to the guide cutting part 411 . For example, when the guide cutting unit 411 is a pair and has an asymmetrical shape, the guide cutting unit 411 introduces the circulating second water into the incision inlet groove 412 through the inlet body 410 . When it is done, it causes a difference in the inflow velocity. This may make it easier to form a vortex with respect to the second water introduced through the fine particle generating member 400 .

The vortex generating protrusion 420 is closely coupled when inserted into the vortex generating chamber protrusion 314 . For this, the outer diameter of the vortex generating protrusion 420 is preferably the same as the inner diameter of the vortex generating chamber protrusion 314 . On the other hand, when the vortex generating protrusion 420 is coupled to the vortex generating chamber protrusion 314, the tip of the vortex generating chamber protrusion 420 is located at a predetermined distance away from the injection hole 316 communicating with the vortex generating chamber protrusion 314. are placed

The induction groove portion 421 is a linear guide groove portion 421 (a) that is formed in parallel with the extending direction of the vortex generation projection 420 on the outer circumferential surface of the vortex generation projection 420, and in the linear guide groove portion 421 (a)). It may include a spiral guide groove portion 421 (b) that extends and increases the strength of the vortex while the second water turns. At this time, the linear guide groove portion 421 (a) is formed with a friction reducing surface 422 that reduces the friction force according to the movement of the second water.

The spiral guide groove portion 421 (b) converts water into fine particles, for example, mist by the capillary principle by the vortex. In addition, the spiral guide groove portion 421 (b) includes a friction reducing surface 422 extending from the linear guide groove portion 421 (a) in the same way as the linear guide groove portion 421 (a). In addition, when the second water turns in the spiral guide groove portion 421 (b), it is preferable that the area of the front inclined surface 423 in contact with the second water becomes narrower. The front inclined surface 423 refers to an inclined surface positioned in front of the second water when viewed from the turning direction of the second water. The second water may be formed into a more powerful vortex through the friction reducing surface 422 and the front inclined surface 423 .

The arc-shaped connecting portion 430 may have a smaller value than the curvature of the connecting protrusion 315 . That is, the arc-shaped connecting portion 430 is more curved than the connecting protrusion 315 . This allows the second water to more smoothly flow into the incision inlet groove 412 .

In addition, the front cover 310 may have a spray hole 316 communicating with the vortex generating chamber protrusion 314 may be formed. And, on the outer surface of the front cover 310, the cross-sectional area expansion portion (b2) of which the cross-sectional area is gradually expanded so that the injection angle (a1) of the second water sprayed through the injection hole (316) has a range of 120 degrees to 150 degrees to be formed. can As the injection angle a1 and the injection speed of the second water injected through the injection hole 316 increase, the second water may be injected more widely. If the injection angle (a1) is less than 120, the injection range for the object to be injected is small and local injection is performed, and if it is larger than 150, the injection range is large and wasteful consumption of water occurs. In addition, if the injection speed does not reach a certain speed, the second water cannot be sprayed far.

On the other hand, at the lower end of the vortex generating chamber protrusion 314 , that is, at a portion communicating with the injection hole 316 , a cross-sectional area reduction part b1 whose cross-sectional area is gradually reduced in the direction in which the second water is sprayed may be formed. The cross-sectional area reduction part b1 may further improve the injection speed of the second water flowing into the injection hole 316 .

In the above, preferred embodiments of the present invention have been exemplarily described, but the scope of the present invention is not limited only to such specific embodiments, and can be appropriately changed within the scope described in the claims.
