Abstract
A water spray nozzle control device has a main body, a rotatable collar, a positioning shaft, a water check collar, a plunger, a water sieve device, and a water stopping washer. The main body has a channel, a hollow threaded head, a handle, and a neck disposed between the handle and the hollow threaded head. The channel receives the water check collar, the plunger, the water sieve device, and the water stopping washer. The hollow threaded head engages with a water spray nozzle. The neck has a through hole receiving the positioning shaft. The rotatable collar encloses the neck.
Description
BACKGROUND OF THE INVENTION
The present invention relates to a water spray nozzle control device More particularly, the present invention relates to a water spray nozzle control device which can adjust an amount of flowing water.
A conventional water spray nozzle control device is used as a switch. The conventional water spray nozzle control device can turn on a water flow which flows into a water spray nozzle or turn off the water folw. However, the amount of flowing water cannot be adjusted by the conventional water spray nozzle control device.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a water spray nozzle control device which can adjust an amount of water flowing into a water spray nozzle.
Another object of the present invention is to provide a water spray nozzle control device which has a positioning block engaging with a plurality of inner teeth in order to control a flowing amount of water.
Accordingly, a water spray nozzle control device comprises a main body, a rotatable collar, a positioning shaft, a water check collar, a plunger, a water sieve device, and a water stopping washer. The main body has a channel, a hollow threaded head, a handle, and a neck disposed between the handle and the hollow threaded head. The channel receives the water check collar, the plunger, the water sieve device, and the water stopping washer. The neck has a through hole receiving the positioning shaft. The rotatable collar has a plurality of inner teeth and two eccentric inner grooves. The rotatable collar encloses the neck. The handle has an outer flange, a front inner stepped flange, a rear inner stepped flange, an inner threaded end portion, and a plurality of anti-skid ribs. The front inner stepped flange blocks the water check collar. The rear inner stepped flange blocks the water stopping washer. A positioning block is disposed on the outer flange of the handle. The positioning shaft has a first distal end, an annular groove, a center camber, an annular recess, and a second distal end. A water stopping gasket is inserted in the annular groove. An annular gasket is inserted in the annular recess. The water check collar has an inner bevel, a round hole, and an enlarged circular hole communicating with the round hole. The plunger has a through aperture, a hollow cylinder, a tube disposed on a top end of the hollow cylinder, an outer bevel formed on a top portion of the hollow cylinder, and four wing plates disposed on the hollow cylinder. The tube is inserted through the round hole of the water check collar. The hollow cylinder is inserted in the enlarged circular hole of the water check collar. The water sieve device has a disk seat and four positioning plates. A plurality of sieve meshes are formed on the disk seat. The eccentric inner grooves of the rotatable collar receive the first distal end and the second distal end of the positioning shaft. When the rotatable collar is rotated to a close position, the rotatable collar forces the first distal end and the second distal end of the positioning shaft to move downward. The outer bevel of the plunger engages with the inner bevel of the water check collar. The positioning block engages with one of the inner teeth. When the rotatable collar is rotated to an open position, the rotatable collar forces the first distal end and the second distal end of the positioning shaft to move upward. The center camber of the positioning shaft blocks the tube. A spacing is formed between the outer bevel of the plunger and the inner bevel of the water check collar. The positioning block engages with one of the inner teeth.

101
.
The handle
102
has an outer flange
18
, a front inner stepped flange
13
, a rear inner stepped flange
14
, an inner threaded end portion
16
, and a plurality of anti-skid ribs
17
.
The front inner stepped flange
13
blocks the water check collar
30
. The rear inner stepped flange
14
blocks the water stopping washer
60
.
The inner threaded end portion
16
engages with a water pipe (not shown in the figures).
