- the shower head 1 is one in which the present invention is applied to a shower device for a bathroom. Tap water is sent at a substantially constant water pressure through a predetermined pipe-When the faucet in the bathroom is opened, cold or hot water is discharged from shower head 1.
- the pipe from the water supply source is also connected to a faucet other than the shower device, and the water pressure in the shower head 1 fluctuates depending on the opening status of the other faucet.
- the shower head 1 is attached to the hose 2.
- the grip tube 3 is fixed to the end of the hose 2 by the stopper 4-
- the disk-shaped shower nozzle 5 is fixed to the opening of the end of the grip tube 3 by the retaining ring 6.
- the shower nozzle 5 is damaged. When clogging occurs, the shower nozzle 5 can be easily replaced by removing the retaining ring 6.
- the shower nozzle 5 is made of a water-resistant elastic material such as rubber, resin (vinyl, nylon, polyethylene, plastic, elastomer, etc.).-A large number of discharge holes H are formed concentrically on the surface of the shower nozzle 5. Have been.
- a plate made of a predetermined elastic material is formed in accordance with the size of the opening of the grip tube 3, and a discharge hole H is formed on the surface with a press or the like, or the discharge hole is formed.
- the nozzle shape including H can be integrally formed by injection molding.
- silicon rubber As a specific material for forming the shower nozzle 5, it is desirable to use silicon rubber. This is because silicon rubber has appropriate water resistance and elasticity, and also has excellent heat resistance and corrosion resistance.
- Silicon rubber is a material whose elastic modulus is unlikely to change due to temperature differences, so that the expansion rate does not change significantly even when the water temperature changes. For this reason, shower nozzles made of silicon rubber are relatively inexpensive. Even when used in a wide range of water temperatures, the difference in the diameter of the discharge holes is small, and the practicality is extremely high ::
- the diameter of the discharge hole H may be set by predicting the expansion rate of the elastic material with respect to the water pressure.
- the hole diameter may be in the range of 0.1 to 0.9 mm, preferably in the range of 0.1 to 0.5 mm.
- the hole diameter is set within the range, it is easy to spout an appropriate amount of shower water effectively without adjusting the opening of the faucet in response to changes in water pressure that occurs in daily life: pore size, the load on the telescopic side (water pressure) force 0 ⁇ 0. 5 kgiZ cm 2 approximately when 0. 1 ⁇ 1. 5 mm approximately, 1 ⁇ 3 kgf Bruno cm 2, when 1 ⁇ 3. 0 mm approximately If you set to, you can take a comfortable shower even if the water pressure fluctuates
- the positions of the discharge holes H may be evenly arranged on the entire surface of the shower nozzle 5 or may be provided intensively at the central portion of the nozzle. This is because the diffusion range of the water becomes narrower, and it becomes easier to apply water to a desired washing point. Further, in the first embodiment, the discharge holes H are arranged on concentric circles. However, other arrangements such as a lattice shape, a random shape, and the like can be used:
- the interval between the discharge holes H can be set in consideration of the thickness of the shower nozzle 5, the hole diameter, and the like. For example, in a home shower head, it is preferable to set the interval to about 1 to 5 mm.
- a locking portion 5 a is provided on the outer peripheral portion of the shower nozzle 5.
- the locking portion 5a is continuous in a ring shape along the outer periphery of the nozzle.
- the thickness of the locking portion 5a is sufficiently larger than the thickness of the expansion and contraction portion of the shower nozzle 5.
- the ring shape of the locking part 5a is integrally formed when the shaping nozzle 5 is formed-As shown in Fig. 2, the locking part 5a is fitted to the tip of the grip tube 3 and the stop ring 6. Possible grooves 3a, 6a are formed.
- the locking part 5a is set in the grooves 3a and 6a and the retaining ring 6 is screwed to the grip tube 3, the locking part 5a is compressed in the grooves 5a and 6a, and the shower nozzle 5. Prevents falling off during expansion and contraction.
- the locking portion a plays a role of a zero ring to prevent water leakage in the shower head.
- the shower head 1 When the shower head 1 is used, if water enters the grip tube 3, the air in the tube is discharged to the outside through the discharge hole H. At this time, since the diameter of the discharge hole H is kept small, the water hardly discharges from the discharge hole H, and temporarily accumulates in the grip tube 3-The water is filled in the grip tube 3 and the water pressure is reduced. As shown in Fig. 3 (A), the shower nozzle 5 expands outward due to the water pressure in the pipe, and the discharge hole H becomes slightly smaller. W 00/22972
- the water in the shower head 1 is ejected from the discharge hole H at a moderate discharge pressure as a shower water.
- the shower nozzle 5 contracts instantaneously as the water pressure drops: At this time, the discharge hole H is expanded as shown in Fig. 3 (B). Return from the large state to the reduced state in Fig. 3 (A), and secure an appropriate amount of shower water.
- Fig. 4 and Fig. 5 show the relationship between the water pressure in the shower head and the discharge pressure .:
- the water pressure in the shower head If the pressure is gradually increased from zero (zero), the shower water will not squirt below a certain water pressure (broken line in Fig. 4) because a sufficient discharge pressure cannot be obtained at the shower nozzle. In other words, the water that has flowed out of the discharge hole is transmitted downward to the shower nozzle and drops downward.
- the discharge pressure increases, shower water is ejected from the ejection hole:
- the diameter of the discharge hole H is enlarged and reduced in accordance with the fluctuation of the water pressure, and the shower can be comfortably taken under a wide range of water pressure.
- An example For example, even if the water pressure changes drastically according to the number of people using the shower device in a bathroom, each bather does not need to readjust the opening of the faucet. Even when the water pressure is low and only a small amount of water is available, the shower water can be spouted effectively: Also, shower head 1 can take a shower with a small amount of water, thus saving water. Useful.
- the conventional shower head required about 20 liters of tap water to take a shower, but the shower head according to the configuration of the present embodiment was used. If this was done, washing could be completed with about half the tap water used in the past.
- the shower head 1 can discharge the shower water to the outside in a more uniform state because the space in the head acts like a chamber: for example, cold water and hot water in the shower head.
- the space in the head acts like a chamber: for example, cold water and hot water in the shower head.
- the water is sufficiently mixed in the space inside the head before discharging from the shower nozzle 5, so that the water temperature of the water in the shower is less scattered. Even when an improving agent is provided, the water quality of the water is likely to be uniform.
- FIGS. 6 and 7 show a second embodiment of the present invention in FIGS. 6 and 7
- the shower nozzle 10 is formed in a dome shape .: On the surface of the shower nozzle 10, discharge holes H are formed concentrically at predetermined intervals. On the outer peripheral portion of the shower nozzle 10, a locking portion 10 a fitted to the tip of the grip tube 12 is formed. As a material for forming the shower nozzle 10, a stretchable material having water resistance is used.
- the diameter of the discharge hole H is larger at the center than at the outer periphery of the dome. This is because when the shower water is discharged from the shower nozzle 10, the discharge amount at the center of the dome becomes smaller at the outer periphery. In order to increase the number.

- a branch pipe 32 for watering is formed.
- a bag-shaped shower head 33 is attached to a tip end of the branch pipe 32 by a band 34 (fastening means).
- the shower head 33 is made of a water-resistant elastic material such as silicon rubber, so that the shower nozzle is integrally formed on the bag surface: shower water is sprayed on the bag surface of the shower head 33. When water is sprayed, water accumulates in the shower head 33 and expands, causing the discharge hole H to expand and allow an appropriate amount of shower water to flow around. Watering crops: When the water pressure in the shower head 33 is low, the discharge hole H is kept at a small diameter, and the discharge pressure is increased to blow the shower water. On the other hand, when the water pressure is high, the discharge hole H expands, and the discharge pressure is suppressed to prevent the water from jumping too much.
- the watering device 30 of the third embodiment even if the water pressure in the watering pipe 31 fluctuates, water is efficiently supplied to a certain range separated from the shower nozzle 33 by a predetermined distance. be able to. In addition, since water is not concentrated in one area, runoff of topsoil is suppressed.
- the shower water can be atomized by reducing the size of the discharge hole H, it is possible to efficiently and evenly spray water on the surface of the crop and the soil.
- the watering device 30 can obtain an excellent watering effect even when used for horticultural cultivation as well as for watering lawns at golf courses and stadiums.

- the sixth embodiment is shown in Figs. 13 and 14-In recent years, as a technique for improving the showerhead, a water quality improver such as activated carbon or perfume has been set in a water channel in the showerhead to reduce There is one that enhances the water quality:
- the shower head 60 of the sixth embodiment contains a water quality improver K in the water passage in the head.
- the water quality improver K is put in the grip tube and the water is improved. It is conceivable to cover the nozzle with a nozzle and tighten the shower nozzle with a stop ring from the outside of the head. However, if the shower nozzle is tightened from the outside of the head in this way, when the water quality improver K is refilled, the shower nozzle is likely to fall off the retaining ring with the retaining ring removed. Therefore, in the sixth embodiment, the shower nozzle 62 is attached inside the nozzle cap 64 to facilitate refilling of the water quality improver K. As shown in FIG. 13, a nozzle cap 64 is screw-fixed to the tip of the grip tube 61. Inside the nozzle cap 64, a compartment for the water quality modifier K is provided by a partition plate 65.
