Detailed Description

For a more intuitive and complete understanding of the technical solution of the present invention, the following non-limiting characteristic description is now performed by combining the drawings of the present invention:

as shown in fig. 1-7, a flow channel control switch for a pesticide spray head comprises a screwing head 4 for connecting a spray head 1, a nozzle 2 and a liquid inlet 3 are respectively arranged at the front end and the rear end of the spray head 1, the screwing head 4 is fixed at the top end of the spray head 1 in a threaded connection mode, an internal thread (not shown) is arranged at the bottom end of the screwing head 4, a sealing film 5 for blocking an internal flow channel 1.1 of the spray head 1 is fixed in the screwing head 4, an internal plug 6 which is positioned above the sealing film 5 and used for pressing the top of the sealing film 5 is arranged in the screwing head 4, the sealing film 5 is clamped at the bottom of the internal plug 6, the middle part of the sealing film 5 is attached to the internal plug 6, the top surface of the outer edge of the sealing film 5 is attached to the inner wall of the screwing head 4, a screwing cap 7 is screwed outside the screwing head 4, two sliding blocks 71 are arranged on the inner wall of the screwing head 7, two corresponding sliding blocks 71 are arranged on the outer wall of, the bottom of the convex column 72 is pressed on the top of the inner plug 6 when the screw cap 7 is screwed.

As shown in fig. 3 and 4, in order to facilitate installation of the inner plug 6, the top end of the inner plug 6 is provided with a latch 61, the middle of the top end of the screwing head 4 is provided with a bayonet 42, the inner wall of the bottom end of the bayonet 42 is provided with a stopper 421, the latch 61 is latched into the bayonet 42, and the stopper 421 stops the latch 61.

As shown in fig. 5 and 6, the spiral groove 41 has an insertion opening 411 at the top end and a horizontal section 412 at the bottom end. The insertion opening 411 allows the slider 71 to be inserted into the spiral groove 41; the horizontal section 412 at the bottom end of the spiral groove 41 is used for stabilizing the screwing state, so that the screw cap 7 is not easy to loosen after being screwed.

As shown in FIGS. 6 and 7, the opening of the insertion opening 411 at the top end of the spiral groove 41 is provided with a convex limiting strip 413, and the bottom end of the sliding block 71 is provided with a chamfer 711. The convex limiting strip 413 is: the depth of the opening of the insertion opening 411 at the top end of the spiral groove 41 is shallower than the depth of other positions of the spiral groove 41, the slider 71 can smoothly slide into the spiral groove 41 avoiding the limitation of the limit strip 413 after being provided with the chamfer 711, and the limit strip 413 can block the top end of the slider 71 to prevent the screw cap 7 from separating from the screw head 4 after the slider 71 slides into the spiral groove 41.

As shown in fig. 2 and 3, a spring 8 is longitudinally arranged between the inner plug 6 and the screwing head 4, the bottom end of the spring 8 is sleeved on the inner plug 6, and the top end of the spring contacts with the inner wall of the top end of the screwing head 4. The spring 8 can play a role in supporting the inner plug 6 and preventing the inner plug 6 from loosening.

The working principle of the utility model is as follows:

when the sliding block 71 in the screw cap 7 is screwed with the screw head 4 along the direction of the spiral groove 41, the convex column 72 in the screw cap 7 presses the inner plug 6 downwards to push the inner plug 6 to move downwards, the inner plug 6 compresses the sealing membrane 5, so that the sealing membrane 5 blocks the flow channel 1.1 in the spray head 1, and the liquid stops flowing; after the screw cap 7 is unscrewed, the convex column 72 in the screw cap 7 moves upwards and releases the pressure on the inner plug 6, and the liquid pushes the middle part of the sealing film 5 open through water pressure, so that the flow channel 1.1 is unblocked.

It is to be understood that the foregoing is only a preferred embodiment of the present invention, and not intended to limit the scope of the invention, which is defined by the following claims and drawings.
