Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a connection structure between a shower head and a hose.

[0002]

2. Description of the Related Art FIG. 4 shows a known connection structure between a shower head used in a bathroom, a washstand or a sink and a hose for supplying hot water from a faucet or the like. 4 will be described briefly.
The connecting cylinder 21 connected to the tip of the
The shower head 24 has a female thread 26 formed on the inner peripheral surface of a cylindrical handle 25, and a watertight sealing material 23 is mounted around the external thread 22 of the connection cylinder 21. By inserting the male screw part 22 into the female screw part 26 of the shower head 24,
The hose 20 is connected to the shower head 24.

[0003] In the above, in order to connect the shower head and the hose, the male thread of the connecting cylinder connected to the end of the hose is screwed into the female thread formed on the inner peripheral surface of the shower head. Since the shower head had to be rotated many times, the connection work was time-consuming, and the workability was poor.

Further, since the shower head needs to form a long internal thread on the inner peripheral surface of the handle, it is necessary to lengthen the entire length of the handle and increase the outer diameter of the handle. If so, it would be difficult to grasp, and the entire shower head could not be made compact, which would restrict the design.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a quick connection between a shower head and a hose, and to make the shower head compact and improve the usability and aesthetic appearance.

[0006]

SUMMARY OF THE INVENTION According to the present invention,
A hose having a connection member having a locking groove formed on the outer peripheral surface connected to a tip thereof, a connection hole into which the connection member is inserted, and an opening for mounting a water discharge member for discharging hot and cold water to the flow path. The shower head is formed from a ring that engages with the locking groove of the connection member.The connection member is inserted into the flow path from the connection hole of the shower head, and the ring is inserted into the flow path from the opening. The hose is connected to the shower head by engaging with the locking groove of the connecting member.

[0007] In the second aspect, the ring is detachable from the locking groove of the connecting member.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. Shower head 1 of the present invention
As shown in FIG. 1, is a hollow bent shape, a flow path 2 through which hot water passes is formed at the tip end, and a water discharging member 4 for discharging hot water to the outside is attached to a lower part of the flow path 2. An opening 3 is formed, and a cylindrical handle 5 formed at a base end for connecting a hose 17 described later accommodates a cylindrical cylindrical member 7 in a connection hole 6 formed therein. Is provided with a serration 7a formed on the inner peripheral surface thereof, and an annular wall 8 is formed between the cylindrical member 7 and the flow channel 2. The distal end of a connecting member 10 described later is inserted into the flow channel 2 through the wall 8. Insertion hole 9 is formed.

The connecting member 10 has a hot water passage 11 therein.
A large-diameter portion 12 which is formed in a substantially cylindrical shape and is connected to the tip of a hose 17, and a large-diameter portion
2, a small-diameter portion 13 formed slightly smaller than the diameter, and an annular flange portion 14 formed between the large-diameter portion 12 and the small-diameter portion 13 to have a larger diameter than the large-diameter portion 12. Since the diameter of the insertion hole 9 formed in the wall 8 of the head 1 is larger than that of the insertion hole 9, the insertion hole 9 cannot be inserted.
Is formed to have a smaller diameter than the insertion hole 9.
Can be inserted into the flow path 2. Small diameter part 13
A locking groove 13a and an annular groove 13b are formed side by side on the outer peripheral surface at a substantially distal end of the annular groove 1a.
A seal member 13c for preventing water leakage is attached to 3b, and a ring 16 to be described later can be engaged with the locking groove 13a facing the flow path 2 from the opening 3 of the shower head 1.

The ring 16 is formed of a material having elasticity and bent in a substantially U-shape, and has an outer diameter larger than that of the insertion hole 9 formed in the wall 8 of the shower head 1 as shown in FIG. Then, if the ring 16 is engaged with the locking groove 13a of the connecting member 10, the connecting member 10
To prevent the hose 17 from falling out of the shower head 1.

The hose 17 is narrow between an inner synthetic resin hose 17a and a metal hose 17b which covers the synthetic resin hose 17a and has a plurality of spiral concave and convex grooves 17c formed at regular intervals on the outer peripheral surface. A groove 18a is formed on the outer peripheral surface of the fixed cylinder 18 held, and a retaining ring 19 having a notch is elastically attached to the groove 18a so as to protrude from the outer peripheral surface of the fixed cylinder 18. . The connecting member 10 has a groove 15 in which the retaining ring 19 is resiliently formed on an inner peripheral surface of a passage 11 formed on an inner periphery of the large diameter portion 12. When inserted into the passage 11 of the connecting member 10, the retaining ring 19 is elastically mounted in the groove 15, so that the connecting member 10 is rotatable with respect to the hose 17 and does not easily come off.

A hose 17 having a connecting member 10 connected to a tip thereof.
Is connected to the shower head 1, the connecting member 10 is first inserted into the connection hole 6 of the shower head 1 as shown in FIG. Then, the flange portion 14 of the connecting member 10 comes into contact with the cylindrical member 7, and the small diameter portion 13 passes through the insertion hole 9 of the wall 8 and faces the flow path 2.

Next, when the ring 16 is inserted from the opening 3 of the shower head 1 toward the flow path 2 and elastically engages with the locking groove 13a of the connecting member 10, the connecting member 10 is connected to the shower head 1. Connected.

Then, as shown in FIG. 3, when the water discharging member 4 is attached to the flow channel 2 from the opening 3 of the shower head 1, the connection between the shower head 1 and the hose 17 is completed.

In order to remove the hose 17 from the shower head 1, the attached water discharging member 4 is removed from the opening 3 of the shower head 1, and a finger is inserted into the flow path 2 to connect the connecting member 10.
When the ring 16 is pulled out of the shower head 1, the hose 17 can be easily disassembled simply by pulling it out of the shower head 1. Therefore, when the hose is damaged or only the shower head is replaced, it can be easily disassembled and replaced.

[0016]

According to the present invention, in the first aspect, a hose in which a connecting member having a locking groove formed in the outer peripheral surface is connected to the tip, a connecting hole into which the connecting member is inserted, and a water discharge for discharging hot and cold water to the outside. A shower head formed with an opening for mounting the member to the flow path, and a ring engaged with the locking groove of the connection member, such that the connection member faces the flow path from the connection hole of the shower head. By inserting the ring into the channel from the opening and engaging with the locking groove of the connection member,
A hose can be connected to the showerhead. Accordingly, the connection between the shower head and the hose can be performed by a simple operation of merely engaging the ring with the locking groove of the connection member, and the connection can be easily performed in a short time, so that the workability is greatly improved. In addition, the shower head does not need to form a screw inside the handle as in the conventional case, and is connected to the connection member at the end of the hose by a ring through a flow path, so that the shower head can be made compact and easily held by hand. Can be used,
Moreover, the degree of freedom in design is increased, and the feeling of use and the appearance can be improved.

According to the second aspect, not only the connection operation but also the disassembly operation can be easily performed, and the hose and the shower head can be easily replaced.
