The cartridge 11 for water purification (see FIGS. 5 and 6) can be accommodated inside the gripping part 11 by releasing the screwing of the relay thread part 11c and separating the cylindrical part 11a and the cylindrical part 11b. In addition, a thick cylindrical hose connection portion 11f provided with a hose attachment screw 11d is formed at the end on the hose attachment side to facilitate attachment / detachment with the hose.

  A push button 13 for switching a channel protrudes from the head 12 at a position opposite to the gripping portion 11 side, and a straight discharge port 12b is formed at the center of the shower discharge port 12a. A switching lever 14 for switching between discharge from the straight discharge port 12b and discharge from the shower discharge port 12a is provided on the downstream side closest to the installation position so as to protrude from the lower surface forming the shower discharge port 12a.

  As shown in FIGS. 5 to 7, a water purification cartridge 15 is accommodated in the shower head 10, and an outer periphery of the water purification cartridge 15 is accommodated in the grip portion 11 that accommodates the water purification cartridge 15. The side flow path 21 is used as a part of the raw water flow path, and the central space 22 of the water purification cartridge 15 is used as a part of the water purification flow path. The mixed water passes through the water purification material 15a of the water purification cartridge 15 from the outer peripheral flow path 21 of the water purification cartridge 15, purifies the water quality, flows out to the central space portion 22, and in the case of discharging raw water Then, it passes through the outer peripheral flow path 21 of the water purification cartridge 15 and is discharged outside.

  The water purification cartridge 15 is disposed so as to be sandwiched between the water purification material 15a formed in a cylindrical shape by providing a hole (central space portion 22) concentrically with the central axis, and the nonwoven fabrics 15b and 15c on the downstream side. The granular or pellet-like sterilizing ceramic 15d is accommodated in two spaces formed by caps 15e, 15f, 15g divided into three parts.

  The water purification material 15a is a water purification on a surface perpendicular to the axial direction in which a cap 15e formed in a cylindrical shape with a bottom provided with a number of slits on the peripheral wall and a hole serving as a fluid passage in the center of the cylindrical shape are formed. It is accommodated in a space provided by a cap 15f having a material support wall and having a fitting portion with each of the other caps 15e and 15g at each end.

  Further, the sterilizing ceramic 15d sandwiched between the nonwoven fabrics 15b and 15c has two cylinders having different diameters from the cap 15f connected by a wall surface perpendicular to the axial direction, and the cap 15f is connected to the larger diameter cylinder of the two cylinders.

[Function and effect]
In the embodiment configured as described above, by operating the push button 13 incorporated in the head 12, the purified mixture is obtained when the push button 13 protrudes from the head 12 (shallow push amount). The raw water flows out in a state where the amount of water that has flowed out and the push button 13 has entered and protruded from the head 12 is small (a deep pushing amount).

  First, when the purified mixed water is flowing out, as shown in FIGS. 16 to 21, when the push button 13 is pressed, the second switching top 13 d in contact with the push button 13 is switched to the first switch. The top 13c is pushed to transmit a pressing force from the first switching top 13c to the switching shaft 13a, and the switching shaft 13a is moved in the direction close to the side wall of the partition member 12c against the urging force of the coil spring 53.

  At this time, when the first switching top 13c slides in the groove of the switching ring 13b and moves until it disengages from the groove, the first switching top 13c pushed by the second switching top 13d becomes the second switching top 13d. According to the shape of the contact portion with the first switching top 13c, it moves so as to change the direction of close contact and rotates as a result, changing the relative position between the first switching top 13c and the end face 36b of the switching ring 13b, The shut-off valve 16 is opened, the shut-off valve 17 is closed, and switching to outflow of non-purified mixed water is performed.

  When the shutoff valve 16 is opened, the shutoff valve 17 is closed, and the mixed water flowing out becomes non-purified mixed water, the switching shaft 13a is returned by the biasing force of the coil spring 53, and the first switching top 13c is provided. The end of the rib contacts the shallow groove side carved in the switching ring 13b to fix the position.

  The push button 13 is pushed again, and the pressing force is transmitted from the second switching top 13d in contact with the push button 13 to the first switching top 13c and further to the switching shaft 13a, thereby resisting the biasing force of the coil spring 53. When the switching shaft 13a is moved in the direction close to the side wall of the partition member 12c, the end of the rib provided on the first switching top 13c is engaged with the shallow groove 36a (361) formed in the switching ring 13b. And the first switching top 13c pushed by the second switching top 13d moves so as to change the direction of contact according to the shape of the contact portion between the second switching top 13d and the first switching top 13c. And the relative position between the first switching top 13c and the end face 36b of the switching ring 13b is changed.

  As a result, as shown in FIGS. 5 to 11, the rib 43 provided in the first switching top 13 c enters the deep groove 36 a (362) in the axial direction of the switching ring 13 b, and the first force is applied by the biasing force of the coil spring 53. The rib 43 provided on the switching top 13c is slid along the groove of the switching ring 13b in a direction away from the side wall of the partition member 12c, and the switching shaft 13a in contact with the first switching top 13c is partitioned. It moves to the direction away from the side wall of the member 12c, the shutoff valve 16 is closed, the shutoff valve 17 is opened, and it switches to outflow of purified mixed water.

  Further, when the shower is being discharged, the valve body 26a is disengaged from the inlet portion of the straight discharge port 12b when the switching lever 14 is operated and rotated around the shaft portion 26b independently of the operation of the push button 13. The mixed water coming out from the collecting passage 25 flows into the inlet portion of the straight discharge port 12b and is discharged straight.

  Further, when the straight discharge is performed, if the switching lever 14 is operated in the opposite direction and rotated in the reverse direction around the shaft portion 26b, the valve body 26a enters the inlet portion of the straight discharge port 12b and passes through the collective passage. The mixed water produced from the portion 25 is prevented from flowing into the inlet portion of the straight discharge port 12b, the flow path is changed to the shower discharge port 12a side, and the shower discharge is performed as shown in FIG.

  In such an embodiment, the restriction of the flow path switching valve composed of the shutoff valves 16 and 17 for switching the water quality can be expanded to a range where it can be incorporated into the head 12, and the size of the flow path switching valve can be increased. Can be greatly relaxed, the operation of the flow path switching valve can be performed on the head 12 side, so that the operability is improved, and the weight distribution between the head 12 and the grip portion 11 can be distributed in a well-balanced manner. The shape and structure can be well balanced in handling the shower head.

  By incorporating the water purification cartridge 15 in the grip 11, a part of the raw water flow path can be formed on the outer peripheral side of the water purification cartridge 15, and the water quality purification provided in the water purification cartridge 15 from this raw water flow path. A part of the purified water flow path that reaches the central space 22 formed in the center via the material 15a can be formed, the flow path configuration can be simplified and compact, and the structure of the gripping part 11 is simplified. More contents of the water purification material 15a can be stored.

  The flow path upstream of the water purification material 15a becomes a shared flow path for raw water and purified water, and solid substances and other accumulated substances that cause clogging accumulated during the purification water discharge can be washed away during the raw water discharge. It is possible to make clogging difficult and extend the life of the water purification material 15a.

  A water purification cartridge 15 is incorporated in the gripping part 11 and a flow path switching valve is incorporated in the head part 12 so that the flow path can be simplified most easily, weight distribution is improved, and handling is extremely balanced. It becomes a good shower head, and it is lightweight and inexpensive.

  The flow path switching valve is an alternating switching type shut-off valve in which the raw water shut-off valve 16 and the purified water shut-off valve 17 alternately shut off the flow path by the same push button 13, so that the push button protruding to the head 12 By pressing 13, the purified mixed water and the non-purified mixed water can be switched and used, and the operability is improved.

  Further, since the raw water shut-off valve 16 and the water purification shut-off valve 17 of the alternating switching shut-off valve are respectively spherical valve bodies 16b and 17b, when the valve is closed, the water pressure applied to the spherical valve bodies 16b and 17b is a coil spring. Together with the urging forces of 16d and 17d, the spherical valve bodies 16b and 17b act so as to be pressed against the valve seats 16a and 17a, so that the sealing can be ensured.

Since the discharge switching valve 26 is formed as a lever-operated shut-off valve, shower discharge and straight discharge can be selected regardless of which of the raw water shut-off valve 16 and the purified water shut-off valve 17 is open. Convenience can be improved.
This shower head 10 with a water purifying function can be used not only in a kitchen but also in a washroom, a bathroom, etc., and has very high versatility.

[Another aspect]
Although this embodiment is specifically described in order to facilitate understanding of the gist of the invention, it does not limit the content of the invention, and thus does not limit another aspect that is not particularly described. It may be changed. In this sense, another embodiment that meets the spirit of the invention is shown below.

[First aspect]

While returning the hose, the shower head 10 with the water purification function is engaged to return to the original state. As a result, the discharge range can be expanded from the immediate position of the mixing faucet 5 to a wide range where the hose is extended, and the appearance around the faucet can be improved and the usability can be improved.

[Second aspect]
In the above-described embodiment, the water purification cartridge 15 is provided with the cap 15e covering the entire water purification material 15a for purifying the mixed water, and the main component is activated carbon solidified in a cylindrical shape on the cap 15e.

It may be changed so that it is exposed.

  In this case, the water purification cartridge 15 is provided with a filter medium 15i on the outer periphery of a water purification material 15a mainly composed of activated carbon, and the cap 15e is formed to hold only the upstream end of the water purification material 15a. Then, the downstream end is held by the cap 15f, and the outermost part of the water purification material 15a covered with the filter medium 15i is exposed.

  Thereby, at the time of raw water discharge, at the time of purified water discharge by the mixed water which passes the outer peripheral side of the water quality purification material 15a covered with the filter medium 15i in the common flow path of the raw water and the purified water upstream of the water quality purification material 15a. Accumulation accumulated on the surface of the filter medium 15i can be washed away, clogging is less likely to occur, and deterioration of the water purification material 15a can be prevented, and the water purification performance can be maintained at a high level for a long period of time.

[Third Aspect]
In the embodiment, the raw water passes as the raw water flow path through the outer peripheral side channel 21 formed on the outer peripheral side of the water purification cartridge 15, passes through the water quality purification material 15 a from the outer peripheral side channel 21 and passes through the central space portion. Although the water purification flow path purified by exiting to 22 is formed, conversely, as shown in FIG. 25, the raw water passes through the central space portion 22 as the raw water flow path, and the water purification is performed from the central space portion 22. A purified water flow path that is purified by passing through the material and flowing out to the outer peripheral flow path 21 may be formed.

  That is, the configuration of the flow path is such that the central portion of the water purification cartridge 15 is formed as a raw water flow path, and the outer peripheral flow path 21 of the water quality purification cartridge 15 is formed as a water purification flow path. With the same configuration as in the above embodiment, the purified water that permeates the water purification material 15a from the central space portion 22 toward the outer periphery by the operation of the push button 13 provided on the head 12, The shower head which switches discharge with the raw | natural water which passes the central space part 22 without permeate | transmitting the water purification material 15a is formed.

  The water purification cartridge 15 includes a water purification material 15a disposed on the inner side mainly composed of activated carbon obtained by providing a central space 22 which is a hole penetrating concentrically with the central axis and solidified in a cylindrical shape, and the activated carbon The water purification material 15k formed into a three-layered cylindrical structure is divided into a sterilizing ceramic 15j arranged on the outer peripheral side and formed into a cylindrical shape, and a filter medium 15i made of a nonwoven fabric covering the outer peripheral side of the sterilizing ceramic 15j. The cap is accommodated in a space formed by the caps 15l and 15m.

  Among these, a hole 15n is formed in the central portion on the end surface of the cap 151, and a hole 15p is formed in the central portion on the end surface of the cap 15m, and the raw water flowing into the grip portion 11 from the faucet (or hose) side is formed in the hole. It passes through 15n and flows into the central space portion 22 so that it can pass through the hole 15p from the central space portion 22 and flow out to the shut-off valve side.

  At the end of the raw water inflow side of the water purification cartridge 15, a protruding cylindrical portion 55 that fits inside the hose connection portion 11 f of the grip portion 11 is formed, and an O-ring groove 56 is cut on the outer peripheral surface of the cylindrical portion 55. The O-ring 57 is fitted into the O-ring groove 56 to prevent leakage between the inner surface of the hose connecting portion 11f and the outer peripheral surface of the cylindrical portion 55, and the raw water is supplied with the purified water channel (outer peripheral channel). 21) Prevent inflow to the side.

  Then, the positions of the raw water side shut-off valve 16 and the purified water side shut-off valve 17 arranged in the head 12 are opposite to those in the above embodiment, and the outer peripheral side flow path 21 of the water purification cartridge 15 is. Is a water purification flow path, a valve disposed at a position communicating with the upstream flow path of the water purification cartridge 15 communicates with the shut-off valve 17 on the water purification side and the central space 22 of the water purification cartridge 15. The valve disposed at the position is the cutoff valve 16 on the raw water side, and the position of the valve seat through which the purified water or raw water passes is shifted to the opposite side to the case of the above embodiment.

  By the arrangement of the shut-off valve, the relationship between the operation of the push button 13 and the opening / closing operation or discharge state of the shut-off valves 16 and 17 is reversed from the case of the above embodiment, and the push button 13 is placed at a shallow push amount position. In some cases, the raw water side shut-off valve 16 is opened, the purified water shut-off valve 17 is closed and raw water is discharged, and when the push button 13 is at a deep pushing position, the purified water side shut-off valve is turned on. 17 becomes the valve open state, the shutoff valve 16 on the raw water side becomes the valve closed state, and the purified water is discharged.

[Fourth aspect]
In the above embodiment, the mixed water forms a flow path so as to reach the purification-side cutoff valve 17 after purification, but conversely passes through the purification-side cutoff valve 17 as shown in FIGS. Then, the water quality may be purified by passing through the water purification material 15a.
That is, the individual members other than the members related to the configuration of the flow path have the same configuration as in the above embodiment, and a shower head that switches between purified water and raw water by the push button 13 provided on the head 12 is formed. Is the same.

The configuration differs from the above embodiment in the following points.
First, an inner cylinder portion 101 that protrudes concentrically to reach the upstream end of the water purification cartridge 15 with a predetermined flow path width is provided inside the cylinder portion 11a that protrudes from the head 12 side. Thus, the raw water channel 102 is formed outside the inner cylinder part 101, and the cartridge outer periphery channel 103 is formed inside the inner cylinder part 101. The cartridge outer peripheral flow path 103 communicates with the flow path 104 on the downstream side of the shutoff valve 17.

  A cartridge receiver 11e into which a cap 15g arranged on the head side of the water purification cartridge 15 is inserted is formed at the front end portion of the inner cylinder portion 101, and the non-purification side shutoff valve 16 is formed from the front end portion. An inner cylinder purified water conduit 106 having a rectangular cross section communicating with the collecting portion 105 formed on the outlet side is formed, and the outside of the inner cylinder purified water conduit 106 communicates with the cartridge outer peripheral passage 103. Thus, the inner side of the inner cylinder purified water conduit 106 becomes a purified water flow path 107 which is a flow path of purified water that has passed through the water purification cartridge 15.

  In this case, the water purification cartridge has an end disposed on the head 12 side in the same manner as in the above-described embodiment, and an end disposed on the raw water inflow side of the grip 11 is an end of the cap 15e. A cap end portion having a bottomed cylindrical shape having a thick portion that is fitted into the tip portion of the inner cylinder portion 101 and contacts the tip surface is formed, and an O-ring groove 15q is formed on the outer peripheral surface of the cap end portion. An O-ring 15r that is in contact with the inner surface of the tip of the inner cylinder portion 101 and prevents liquid leakage is fitted into the O-ring groove 15q.

  The thus formed water purification cartridge 15 is inserted into the inner cylinder portion 101, the tip cap 15g is fitted into the cartridge receiver 11e, and the cap end of the cap 15e abuts against the tip of the inner cylinder portion 101. When the position is fixed, the cartridge outer peripheral flow path 103 is formed by a gap formed between the inner cylinder portion 101 and the water purification cartridge 15.

  Thereby, when raw water flows in from the hose connection part 11f of the gripping part 11, it passes through the raw water flow path 102 formed on the outer peripheral side of the inner cylinder part 101, and a common valve provided upstream of the shutoff valves 16 and 17 It flows into the inner space and is divided into raw water discharge or purified water discharge depending on the position of the push button 13.

  In the case of water purification discharge, as shown in FIG. 27, the cartridge outer peripheral flow path passes through the valve seat 17a of the shutoff valve 17 and passes from the downstream flow path 104 to the outside of the inner cylinder purified water conduit 106. 103, flows through the water purification material 15a of the water purification cartridge 15 and flows out to the central space 22, passes through the non-woven fabric 15b, the sterilizing ceramic 15d, and the non-woven fabric 15c from the central space 22, and further passes the inner cylinder. After passing through the purified water flow path 107 inside the inner purified water conduit 106 and flowing out to the collecting portion 105 and passing through the sintered magnetic body 19, it flows out to the outside by shower discharge or straight discharge.

  Thus, a shower head having a flow path from the shut-off valve 17 to the water purification cartridge 15 can be formed, and the flow path switching valves 16 and 17 can be provided on the upstream side of the water purification cartridge 15. Therefore, the flow path switching valves 16 and 17 can be provided on either the upstream side or the downstream side of the water purification cartridge 15, both of which are operated by operating the push button 13 provided on the head 12. Either purified mixed water or non-purified mixed water can be selected, and these can select straight discharge and shower discharge separately from the selection of purified water and raw water.

[5th aspect]
As another aspect of the fourth alternative aspect, the inner cylinder portion is formed short, and a part of the flow path after passing through the shutoff valve is provided inside the water purification cartridge connected to the short inner cylinder portion. What you did is fine.

  That is, in place of the water purification cartridge 15, as shown in FIGS. 28 and 29, a cartridge case 111a formed in a bottomed cylinder with a certain gap is provided on the outer peripheral side of each cap 15e, 15f, 15g. A new water purification cartridge 111 having a heavy wall structure is formed. A gap formed between the cartridge case 111a of the water purification cartridge 111 and each of the caps 15e, 15f, and 15g is defined as a raw water flow path 113 via the shutoff valve 17.
