Detailed Description

The utility model will be further described with reference to examples of embodiments shown in the drawings to which:

as shown in fig. 1 to 6, an adjustable dual spray head comprises a three way joint 1, wherein the three way joint 1 comprises a first through pipe 101, a second through pipe 102 and a third through pipe 103 which are communicated with each other, the first through pipe 101 is connected with a spray rod of a sprayer, a normally open spray head 2 is sleeved on the second through pipe 102, an adjustable spray head 3 which is independently opened and closed is sleeved on the third through pipe 103, the normally open spray head 2 can rotate 360 degrees along the circumferential direction of the second through pipe 102, and the adjustable spray head 3 can rotate 360 degrees along the circumferential direction of the third through pipe 103. Normally open shower nozzle 2 and adjustable shower nozzle 3 all cup joint on three way connection 1, and can 360 degrees rotations separately, the angle modulation of spraying the scope is wider and nimble. The adjustable spray head 3 can be independently opened and closed, when the adjustable spray head 3 is closed, the adjustable spray head can be used as a single spray head, and when the adjustable spray head 3 is opened, the adjustable spray head is used as a double spray head.

The front ends of the second pipe 102 and the third pipe 103 are respectively provided with a retaining groove 104 and a baffle ring 105, and the pipe wall provided with the retaining groove 104 section is provided with a liquid outlet 5 penetrating through the pipe wall.

Be equipped with first injection passage 201 in the above-mentioned normally open shower nozzle 2, a threaded connection of normally open shower nozzle 2 has end cap 202, and end portion embedding second siphunculus 102 in the end cap 202 gos deep into first injection passage 201 is in stopping groove 104, and stopping groove 104's front end still has fender ring 105, blocks end cap 202 and moves outward, ensures that normally open shower nozzle 2 can not break away from with three way connection 1 and drop 360 degrees rotatory in-process. The other threaded connection of normally opening shower nozzle 2 has nozzle 4, and nozzle 4 cup joints on the outer wall of normally opening shower nozzle 2, is equipped with the hydrojet mouth 6 that feeds through first injection path 201 on the 2 lateral walls of one end normally opening shower nozzle that are equipped with nozzle 4, and on liquid sprayed nozzle 4 inner wall through hydrojet mouth 6, liquid was atomized behind 4 inner walls of striking nozzle, sprayed away through nozzle 4 again.

Be equipped with second injection passage 301 in above-mentioned adjustable shower nozzle 3, nozzle 4 has been cup jointed to one end of

adjustable shower nozzle

3, 4 threaded connection of nozzle are on adjustable shower nozzle 3, be equipped with the hydrojet mouth 6 that feeds through second injection passage 301 on this adjustable shower nozzle 3 lateral wall that is equipped with nozzle 4, be equipped with the case 302 of closing hydrojet mouth 6 in the second injection passage 301, the one end fixedly connected with regulation end 303 of case 302, regulation end 303 extends to adjustable shower nozzle 3 not have nozzle 4 one end outside. The adjusting end 303 is positioned in the adjustable spray head 3 and is in threaded connection with the inner wall of the adjustable spray head 3. The valve element 302 can be moved forward or backward by rotating the adjusting end 303 portion located outside the adjustable nozzle 3, so that the valve element 302 blocks the liquid outlet 6 or opens the liquid outlet 6.

The second injection passage 301 includes a first passage 3001 and a second passage 3002, the diameter of the second passage 3002 is smaller than that of the first passage 3001, the liquid injection port 6 is located on a side wall of the adjustable nozzle 3 corresponding to the second passage 3002, the diameter of the valve core 302 is smaller than the inner diameter of the second passage 3002 and smaller than that of the first passage 3001, the end of the valve core 302 is tapered, and the end shape of the second passage 3002 is matched with that of the valve core 302. When the valve body 302 is inserted into the second channel 3002 by rotating the adjustment end 303, the diameter of the valve body 302 is larger than that of the second channel 3002, so that the valve body 302 fills the second channel 3002, and when the valve body 302 blocks the liquid ejecting port 6 of the second channel 3002, the liquid ejecting port 6 is blocked. The end of the spool 302 is tapered to allow the spool 302 to more easily enter the second passage 3002.

The adjustable nozzle 3 is fitted to the inner wall of the third pipe 103 and provided with a boss 304 extending toward the third pipe 103, the boss 304 is fitted into the retaining groove 104 of the third pipe 103, and the stopper ring 105 of the third pipe 103 is provided with a notch 106. The baffle ring 105 blocks the boss 304 to prevent the boss 304 from being separated from the retaining groove 104 of the third tee 103, but the baffle ring 105 also blocks the adjustable spray nozzle 3 from being installed in the third tee 103, so the notch 106 is arranged on the baffle ring 105 of the third tee 103 to ensure that the boss 304 can be installed in the retaining groove 104 through the notch 106, meanwhile, the outer diameter of the baffle ring 105 at the notch 106 is slightly overlapped with the edge of the boss 304, the baffle ring 105 at the notch 106 can also block the boss 304 from being separated from the retaining groove 104, and when the adjustable spray nozzle 3 is installed, the boss 304 is pushed forcibly to deform the boss 304 so as to be clamped in the retaining groove 104.

The basic working principle is as follows: a first through pipe 101 of the three-way joint 1 is arranged on a spraying handle or a spraying liquid inlet pipeline, and liquid medicine enters the first through pipe 101 and then is shunted to the normally open nozzle 2 and the adjustable nozzle 3 through a second through pipe 102 and a third through pipe 103. In the liquid spraying process, the normally open nozzle 2 and the adjustable nozzle 3 can be manually rotated to any angle, so that the liquid spraying direction and angle can be adjusted at any time, and liquid spraying operation can be carried out on different positions and corners. The normally open sprayer 2 and the adjustable sprayer 3 are sleeved on the second through pipe 102 and the third through pipe 103, friction force between the normally open sprayer 2 and the second through pipe 102 and friction force between the adjustable sprayer 3 and the third through pipe 103 can enable the normally open sprayer to be fixed at the angle when no external force acts on the normally open sprayer 2 and the second through pipe 102, and the normally open sprayer and the adjustable sprayer cannot rotate in the liquid spraying process. The two spray heads spray liquid simultaneously, so that the efficiency of liquid spraying work is improved. When two nozzles are not needed to spray liquid simultaneously, the adjusting end 303 of the adjustable nozzle 3 is rotated to make the valve core 302 go deep into the second channel 3002 of the adjustable nozzle 3 to block the liquid spraying port 6 at the position, thereby closing the liquid spraying function of the adjustable nozzle 3.
