  • the present invention solves the problem of a filter system having a filter cartridge rotating around a single neck described hereinabove.
  • the present invention provides a filter cartridge and a filter head that has a simple structure and completely blocks a space between inlet and outlet ports, thereby preventing unfiltered and filtered water from mixing together between the inlet port and the outlet port.
  • a filter cartridge and a filter head for purifying water has an independent structure for inlet and outlet ports, thereby fully preventing water from mixing together between the inlet port and the outlet port.
  • an outlet passage is disposed at a center of the filter cartridge, and an inlet passage is provided apart from the outlet passage at a predetermined distance that the inlet passage may open or close a check valve provided at a filter head, thereby constituting a structure with a simple mechanism.
  • FIG. 1 is a sectional view of a filter cartridge and a filter head of the present invention in a disengaged state.
  • FIG. 2 is a perspective view of a filter cartridge of the present invention.
  • FIG. 3 is a perspective view of a filter head of the present invention.
  • FIG. 4 is a perspective view of a valve housing of the present invention.
  • FIG. 5 is a perspective view of a check shaft disposed at a filter head of the present invention.
  • FIG. 6 is a perspective view of a check housing disposed at a filter head of the present invention.
  • FIG. 7 is a sectional view of a filter cartridge and a filter head of the present invention in an engaged state. Best Mode for Carrying Out the Invention

  • a filter head includes: a cap member connected with a housing of a filter cartridge, having an inlet through which unfiltered water is introduced, and having locking tabs that are engaged with a locking tab of the housing; and a check valve disposed inside the cap member and controlling water flow by opening or closing the inlet.
  • FIG. 1 is a sectional view of a filter cartridge 2 and a filter head 12 in a disengaged state.
  • the filter cartridge 2 includes an approximately cylindrically shaped housing 4 and a filtering member 6 provided in the housing 4.
  • the housing 4 includes a protruded inlet port 8 through which water is supplied to the filtering member 6, and a protruded outlet port 10 disposed at a center portion of the housing 4 and through which water filtered by the filtering member 6 is drained.
  • locking tabs 14 are formed on an outer peripheral surface of a neck portion of the housing 4 for connecting the housing 4 with the filter head 12.
  • FIG. 2 is a perspective view of the filter cartridge 2 of the present invention.
  • the locking tabs 14 are formed at an upper part of the housing 4, that is, disposed on opposite sides around the neck portion, and have an inclined surface 16 for easy engagement with the filter head 12.
  • the filter head 12 includes: an approximately cylindrically shaped cap member 20 having an inlet 18 through which unfiltered water is introduced, and connected with the neck portion of the housing 4; engaging tabs 22 disposed at an inner surface of the cap member 20, and that are engaged with the locking tabs 14; and a sleeve 24 protruded inside at a center portion of the cap member 20.
  • Two of the engaging tabs 22 are provided facing each other on the inner surface of the cap member 20 in order to be engaged with the locking tabs 14 formed on the housing 4.
  • a valve housing 28 is disposed inside the cap member 20.
  • the valve housing 28 includes: an outlet 30 inserted into the sleeve 24 formed in the cap member 20, and into which the outlet port 10 of the housing 4 is inserted for draining out water filtered by passing through the filtering member 6; a sleeve 32 into which the inlet port 8 of the housing 4 is inserted; and a base 36 formed as a single piece with one end of each of the outlet 30 and the sleeve 32, disposed at an entrance side of the cap member 20, and closing an entrance portion of the cap member 20 to thereby form a predetermined chamber region 34 inside the cap member 20.
  • a barrier 38 is protrusively formed on an outer surface of the base 36 that may closely adhere to an inner surface of the cap member 20, thereby preventing water filled in the chamber region 34 from leaking out therefrom. Further, a packing groove
  • the sleeve 32 is disposed in a chamber region 34 of the cap member 20.
  • the sleeve 32 includes a check valve 42 disposed therein such that unfiltered water is blocked or allowed to flow to the filter cartridge 2.
  • the check valve 42 includes: a check shaft 44 disposed in the sleeve 32; a spring 46 elastically pressing down on the check shaft 44; and a check housing 48 supporting the spring 46 in the top direction.
  • the check housing 48 is welded on the sleeve 32 to form a single piece therewith, and is disposed in the chamber region 34 formed inside the cap member 20.
  • the check shaft 44 includes: a spring seat 50 supporting the spring 46, and a valve spool 52 formed as a single piece with the spring seat 50 and that allows or blocks water flow.
  • the valve spool 52 closes a passage disposed inside the sleeve 32 by abutting against a plane of an inner flange 54 formed inside the sleeve 32.
  • the check shaft 44 has a cylinder 56 formed at a lower part of the valve spool 52.
  • the cylinder 56 is formed with a plurality of pores 58.
  • the check housing 48 has a bonding portion 60 that is attached to the sleeve 32 by a thermal bonding process, and further has a spring seat 62 in order to support the spring
  • the spring seat 62 is approximately cylindrically shaped having a plurality of passages 64 along an outer surface thereof that allow water to flow from the inlet 18 toward the check shaft 44.
  • the check valve 42 blocks passages formed inside the sleeve 32.
  • the spring 46 presses down the check shaft 44, and thus the valve spool 52 abuts against the plane of the inner flange 54 formed inside the sleeve 32.
  • the unfiltered water may not pass the sleeve 32.
  • the unfiltered water is filled in the chamber region 34 formed inside the cap member 20.
  • the filter cartridge 2 is pushed up. Subsequently, the inlet and the outlet ports 8 and 10 are inserted into the sleeve 32 and the outlet 30, respectively, as shown in FIG. 7.
  • the inlet port 8 is rotated in the chamber region 34 in which water is always filled, such that no problems are encountered with respect to purifying water.
  • the filter cartridge of the present invention includes the inlet and outlet ports independently, the inlet port is rotated within the cap member in which water is always filled and around the outlet which is the axis of rotation. Hence, no problems are encountered with respect to providing water toward the filter cartridge.
  • the structure of the water passage toward the filter cartridge and the check valve provided to the water passage may be installed at two separate passages that are conventionally installed at a single passage, thereby resulting in easy manufacture and assembly.

Abstract

La présente invention concerne une cartouche de filtre et une tête de filtration comportant : un boîtier de filtre comprenant un orifice d'entrée à travers lequel de l'eau non filtrée est introduite, un orifice de sortie à travers lequel de l'eau filtrée par un organe de filtration est évacuée, et un organe de filtration ; un élément de coiffe engagé avec le boîtier de filtre, formant une zone d'enceinte où l'eau non filtrée est temporairement stockée, et comprenant un orifice d'entrée formé dans une direction extérieure à travers lequel l'eau est introduite et une gaine formée dans la direction intérieure au niveau d'une partie centrale ; et un clapet de non-retour disposé dans la zone d'enceinte, et qui bloque l'écoulement d'eau depuis l'orifice d'entrée vers le boîtier de filtre avant l'engagement du boîtier de filtre et permet l'écoulement de l'eau vers le boîtier de filtre lorsque le boîtier de filtre est engagé. Le boîtier de filtre s'engage avec l'élément de coiffe par la rotation du boîtier de filtre.
