Further, the convenience of the shower head (water discharging device) can be enhanced more than before.

Further, in the case of this shower head, since the water discharge / stop operation section opens and closes the pilot water channel, specifically, it opens and closes a pilot valve that opens and closes the pilot water channel. Water shutoff operation can be performed.

A main valve is provided in a joint unit connected to a shower hose connected to a shower head or in a water faucet main body, and a tube is extended from the main valve to a water discharge / stop section in the shower hose. It is also conceivable to open and close the pilot channel formed in the tube with the water discharge / stop operation section.

However, in this case, when an attempt is made to provide a water discharge / stop operation function to an existing shower head,
Modification or replacement of the shower head alone is not sufficient, and modification and improvement of the shower head, the entire joint unit, and the faucet body are required. However, the shower head (water discharging device) of the present invention has all the functions necessary for the water discharging and stopping operation, and thus has an advantage that the shower head alone can be used.

In a second aspect of the present invention, a part of a body of a water discharge device comprising a shower head or a water discharge pipe having a main valve, a back pressure chamber, a pilot water passage, a pilot valve and a water discharge / stop water operating portion is formed in a housing.

In this case, the main valve is installed in the fitting space, and the cartridge is fitted in the fitting recess, so that the water discharging device has a function of stopping water discharge. However, in this case, it is difficult to form the main valve seat and the main valve fitting space for the main body, and to form the main valve seat and the main valve fitting space for each main body of various types of water discharge devices. Because of the necessity, the problem of inevitably increasing the types of the main body occurs.

According to a third aspect of the present invention, the cartridge includes a main valve seat, a main valve, an entire back pressure chamber, a part of the main water passage upstream and downstream of the main valve, and a pilot water passage. In the water discharge device according to the third aspect, since the cartridge is provided with all the functions necessary for the water discharge and stop operation including the main valve seat, the above-described inconvenience occurs. A water discharging device with a water discharging and stopping operation function can be configured without the need.

Therefore, in the water discharging device of the third aspect, it is not necessary to form the main valve seat and the main valve fitting space in the main body, so that the main valve seat and the main valve fitting space are formed in the main body. Therefore, the main body can be shared for all types of water discharge devices. That is, the water discharge / stop operation function can be easily added to various types of water discharge devices simply by fitting the cartridge into the fitting recess while using the common main body.

Next, the main channel is opened on the outer peripheral fitting surface of the cartridge and the inner peripheral fitting surface of the fitting recess, and the main channel is connected by the fitting surfaces. None, and an elastic seal ring is interposed between the fitting surfaces to seal the connection portion of the main waterway in a water-tight manner. When the function is added, water leakage from the connection part of the main waterway can be effectively prevented.

According to a fifth aspect of the present invention, one of the elastic seal rings is interposed between the bottom surface of the cartridge and the bottom surface of the fitting recess. Can prevent water leakage. In addition, in this case, there is an advantage that the flow path on the primary side of the main water channel, that is, the flow path on the upstream side of the main valve can be formed wider.

Claims 2 to 5 are suitably applicable to a shower head having a shower water discharging function, a rectifying water discharging function, and a switching function of switching the water discharging from the shower water discharging to the rectifying water discharging or vice versa. In this way, it is possible to switch from shower water discharge to rectified water discharge or vice versa by hand operation while holding the shower head in hand, and at the same time, perform water discharge stop operation, which is convenient for the shower head. The nature becomes high.

In the present invention, the water discharging / stopping operation section can be formed as a push-operation type switch operation section. With this configuration, the water can be easily discharged and operated simply by operating the switch on the water discharge and operation section. Further, in this case, the water discharge / stop operation unit may be a seesaw type switch operation unit that performs the water discharge operation and the water stop operation each time the opposite ends are pushed in (claim 8). . Further, the main valve may be constituted by a diaphragm valve (claim 9).

In the first embodiment, the main valve seat 50 for abutting the main valve 52 on the main body 44 side is formed integrally with the main water passage 26, and the fitting space of the main valve 52 is reduced. The entire shower head 14 is formed by incorporating the main valve 52 therein and fitting the cartridge 42 into the fitting recess 48. In this case, the main valve 44 for the main body 44 is provided. It is difficult to form the fitting space of the seat 50 and the main valve 52, and the fitting space of the main valve seat 50 and the main valve 52 must be formed for each of various types of shower head bodies. Therefore, there arises a problem that the types of the main body 44 inevitably increase.

On the other hand, in the shower head 14 according to the present embodiment, since the cartridge 42 has all the functions necessary for the water discharging and stopping operation including the main valve seat 50, the above-described inconvenience may occur. Thus, the shower head 14 with the water discharge / stop operation function can be configured without using it.

In the shower head 14 of this embodiment, the main body 44
The main valve seat 50 and the main valve 52 do not need to form a fitting space on the side, so that the main valve seat 5 and the main valve seat

That is, by simply fitting the cartridge 42 into the fitting recess 48 while using the common main body 44, it is possible to easily add a water discharge / stop operation function to various types of shower heads.

FIGS. 10 and 11 show still another embodiment of the present invention. This example is similar to the example of FIGS.
Instead of the elastic seal ring 94 on the bottom side of the fitting recess 48, an elastic seal ring 96 is interposed between the bottom surface of the cartridge 42 and the bottom surface of the fitting recess 48. This is an example in which a connection portion of the main water channel 26 is sealed in a watertight manner by an elastic seal ring 94 on the opening side of the fitting recess 48. According to this example, the main waterway 2
6, the flow path on the primary side, that is, the flow path on the upstream side of the main valve 52 can be formed wider.

The embodiment of the present invention has been described in detail above, but this is merely an example. For example, the present invention can be applied to a shower head at the end of a water discharge pipe in a faucet device of various forms and types, or can also be applied to a shower head in a bathroom.

Further, the present invention can be applied to the tip of a normal water discharge pipe whose tip is not configured as a shower head. In the above example, a diaphragm valve is used as the main valve. However, the present invention can be variously modified without departing from the gist of the present invention. For example, a sliding valve or other valves of other forms can be used as the main valve. Can be configured.
