511
and
522
. When the outer side of the water distribution disk
40
is fastened with the inner side of the face plate
23
of the water emission cover
20
, the full flow hole
24
of the face plate
23
is obstructed by the annular side
41
of the water distribution disk
40
. The arcuate bodies
50
,
51
, and
52
of the water distribution disk
40
are fitted into the recessed arcuate edges
332
,
342
, and
352
of the locating walls
331
,
341
, and
351
of the face plate
23
. The tubular bodies
30
and
31
of the inner side of the face plate
23
, and the locating walls
331
,
341
and
351
are in intimate contact with the outer side of the water distribution disk
40
. The through hole
46
of the water distribution disk
40
, the guide slot
461
, and the locating hole
43
are in communication with the tubular bodies
30
and
31
. The guide hole
501
of the first arcuate body
50
of the water distribution disk
40
is in communication with the outer annular mesh
29
of the water emission cover
20
. The guide hole
511
of the second arcuate body
51
is in communication with the inner annular mesh
27
of the water emission cover
20
. The guide hole
522
of the third arcuate body
52
is in communication with the full flow hole
24
of the water emission cover
20
.
The present invention is characterized by the water distribution disk
40
which is provided in the annular side
41
with a plurality of round holes
53
which are circularly arranged and are corresponding in location to the ribs
22
of the water emission cover
20
. The round holes
53
are in communication with the guide hole
522
of the water distribution disk
40
by the annular slot
54
of the water distribution disk
40
. The water distribution disk
40
is fastened with the water emission cover
20
by the high frequency wave process.
As shown in FIGS.
8
and
8
-
1
, a water flow
1
is guided into the guide hole
522
via the through hole
461
of the water distribution disk
40
. The water flow
1
is further guided into the full flow hole
24
of the water emission cover
20
via the annular slot
54
of the water distribution disk
40
and the round holes
53
of the annular side
41
of the water distribution disk
40
. In light of the water distribution disk
40
being fastened with the water emission cover
20
by the high frequency wave process, the water flow
1
can not flow in reverse into the interior of the head seat
11
, thereby allowing the water flow
1
to be emitted from the full flow hole
24
. In light of the round holes
53
being aligned with the ribs
22
of the water emission cover
20
, the water flow
1
is collided with the ribs
22
to spread out.
