ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a press structure of washing head for kitchen cabinet. When assembling the press lever, the engaging cavity of the press lever is pushed forward to engage into the engaging tongue of the main body. After assembly, the press lever is received in the press lever cavity of the main body without any gap between the press lever and the outer side of the main body. Therefore, in assembling or use, the structure is prevented from being broken or damaged and the using life is prolonged.
FIG. 1
shows a press structure of the washing head of an existing kitchen cabinet. The press structure includes a main body
100
, an adjusting/controlling valve
200
, a spring
300
, a stopper plate
400
, a connecting body
500
, a water injecting body
600
, a water injecting cap
620
, a screw
630
, a decorative cap
640
, a sleeve
600
and a press lever
800
. In the end opening
110
of the head section of the main body
100
is disposed a locking post
1110
. The connecting opening
120
of the lower end of the grip is formed with an inner thread
1210
. The upper end of the grip is disposed with an upward extending socket
1220
. The top edge of the rear section of the head of the main body
100
is disposed with a recessed section
130
. The upper end of the recessed section
130
is disposed with a rectangular engaging section
1310
with a certain height. Two sides of the engaging section
1310
are respectively formed with two rectangular engaging cavities
1320
. The top end of the adjusting/controlling valve
200
is disposed with a projecting conic body
210
. The upper section of the valve
200
is fitted with a small water sealing ring
220
. The middle section is fitted with a large water sealing ring
230
. The lower section is formed with a stopper edge
240
. The centers of two faces of the stopper plate
400
are respectively formed with two recesses
410
. The top face of the connecting body
500
is disposed with an upward projecting hollow boss
510
formed with outer thread
520
. The lower side of the boss
510
is disposed with a flange
530
. The outer circumference of the middle diameter step of the water injecting body
600
is inserted with a water sealing ring
610
. Two sides of front end of the press lever
800
are respectively disposed with two engaging arms
810
. The middle and rear sections are formed as a lever section
820
. The bottom face of front section is disposed with two semicircular pressing blocks
830
.
FIG. 2
shows the assembly of the conventional washing head. When assembled, the adjusting/controlling valve
200
is fitted into the connecting opening
120
of the main body
100
with the upper end of the adjusting/controlling valve
200
protruding out of the extending socket
1220
of the main body
100
. The spring
300
is fitted into the connecting opening
120
of the main body
100
. The upper end of the spring
300
abuts against the stopper edge
240
of the lower section of the adjusting/controlling valve
200
. The stopper plate
400
is fitted into the connecting opening
120
of the main body
100
. The lower end of the spring
300
abuts against the recess
3
\
410
of the top face of the stopper plate
400
. The outer thread
520
of the boss
510
of the connecting body
500
is screwed with the inner thread
1210
of the connecting opening
120
and the flange
530
of the connecting body
500
abuts against the end edge of the connecting opening
120
. The end face of the boss
510
of the connecting body
500
upward pushes the stopper plate
400
to slightly compress the spring
300
. The two engaging arms
810
of the press lever
800
are forcedly pivotally fitted into the engaging cavities
1320
of two sides f the engaging section
1310
of the recessed section
130
of the main body
100
. The projecting conic body
210
of the adjusting/controlling valve
200
is received in the space between the two semicircular pressing blocks
830
of the press lever
800
. The small and middle diameter steps of the water injecting body
600
are fitted into the end opening
110
of the main body
100
. The water injecting cap
620
is plugged into the middle diameter step of the water injecting body
600
. The screw
630
is passed through the stepped hole of the water injecting cap
620
and screwed with the locking post
1110
of the main body
100
. Then the decorative cap
640
is inserted on the end opening of the water injecting cap
620
. Finally, the sleeve
700
is fitted with the head section of the main body
100
to complete the assembly.
When injecting water, the lever section
820
of the press lever
800
is depressed to make the two semicircular projecting blocks
830
downward press the adjusting/controlling valve
200
. The small water sealing ring
220
is downward frictionally slid against inner wall of the extending socket
1220
. The stopper edge
240
of the adjusting/controlling valve
200
downward compresses the spring
300
. At this time, the large water sealing ring
230
of the valve
200
and the inner wall of the conic grip of the main body
100
define a gap through which the water flows from the connecting opening
120
to be injected from the water injecting hole between the water injecting body
600
and the water injecting cap
620
. When shutting off the water, the lever section
820
is released and the valve
200
is upward resiliently pushed by the spring
300
. The small water sealing ring
220
is upward frictionally moved against the inner wall of the extending socket
1220
to push the press lever
800
back to its home position. At this time, the large water sealing ring
230
of the valve
200
tightly abuts against the inner wall of the grip of the main body
100
and the water incoming from the connecting opening
120
is stopped by the large water sealing ring
230
and shut off.
The above conventional structure has some shortcomings as follows:
1. When fitting the engaging arms
810
of the press lever
800
into the engaging cavities
1320
of the engaging section
1310
, the engaging arms
810
are forcedly stretched laterally and then engaged into the engaging cavities
1320
of the main body
100
. Such operation tends to break the engaging arms
810
and makes it impossible to assemble the washing head.
2. When assembling the press lever
800
with the main body
100
, the spring
300
resiliently abuts against the adjusting/controlling valve
200
. Therefore, the rear section of the press lever
800
is lifted by a certain height to form a gap between the press lever
800
and the outer side thereof. This gap is likely to hook an adjacent article in use and incautiously pull and break the press lever
800
.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide a press structure of washing head for kitchen cabinet. When assembling the press lever, the engaging cavity of the press lever is pushed forward to engage into the engaging tongue of the main body with the stopper section of the press lever abutting against the upper side of the stopper tongue of the main body. By such assembling operation, the structure is prevented from being broken or damaged.
It is a further object of the present invention to provide the above press structure of washing head for kitchen cabinet in which after assembled, the press lever is received in the press lever cavity of the main body without any gap between the press lever and the press lever cavity. Therefore, the adjacent article will not be hooked and the breakage of the structure is avoided. In case a strong force upward pulls the press lever, the stopper section thereof will move upward and backward to disengage from the stopper tongue of the main body and lose the engaging force. Therefore, the engaging cavity of the press lever will be entirely separated from the engaging tongue of the main body to avoid damage of the structure. When installing the press lever back, the engaging cavity of the press lever is pushed forward to engage i
