The dimensions in the drawings of the present invention are appropriately scaled.

When the spray head works normally, pressurized liquid enters the lower cavity through the liquid inlet, and the liquid is filtered by the filter screen on the filter screen and is atomized and sprayed out from the spray nozzle atomization core. At the moment, the pressure in the lower cavity of the atomizing nozzle is in a normal range, the inner side of the corrugated expansion piece is pressed to extend upwards and deform, and meanwhile, the clamp spring release blocking piece is driven to ascend, but the ascending height cannot reach the clamp spring at the moment, the clamp spring keeps blocking the sliding sealing piece to prevent the sliding sealing piece from moving upwards, the sliding sealing piece is in contact with the inner wall of the nozzle shell, so that the sliding sealing piece can keep sealing the discharge port, the sliding sealing piece is blocked and cannot move upwards while the clamp spring release blocking piece ascends, and an upward pushing spring in the sliding sealing piece is.

When the liquid flowing through the filter screen is precipitated; when the filter screen is blocked by the solidification phenomenon, the pressure in the lower cavity of the spray head is further increased, the corrugated expansion piece is pressed to extend upwards and deform to a set height, and the snap spring releases the blocking piece to rise to the snap spring; the one-way hook on the clamp spring moves outwards, the sliding sealing piece loses the blocking effect and quickly bounces up under the action of the compressed push-up spring, the sliding sealing piece moves away from the discharge port, at the moment, a new flow channel is formed between the liquid inlet and the lower cavity of the spray head to the discharge port, and the blocking object is flushed out downwards from the discharge port through the discharge port outlet while the liquid flowing through the liquid inlet is pressurized to flush the filter screen and the lower cavity. Then, the pressure in the lower cavity of the spray head is reduced, and the lower pressing spring pushes the corrugated expansion piece downwards to contract; a sliding connector connected with the corrugated expansion piece; the clamp spring releases the blocking piece and moves downwards at the same time, and the sliding connecting piece moves downwards and pushes the sliding closing piece to the lower side of the clamp spring one-way hook so that the sliding closing piece is locked by the one-way hook again; the sealing slide on the sliding closure again closes the discharge opening. The pressurized liquid in the lower cavity of the nozzle is recovered and filtered by the filter screen, and is atomized and sprayed out from the atomizing core of the nozzle.

The recovery process is influenced by the central air pressure balance hole of the blockage-removing pressure adjusting knob, the air pressure balance hole delays the air speed entering the upper cavity in the process of pushing the spring down to push the corrugated expansion piece to contract, so that the upper cavity is temporarily in a negative pressure state to slow down the contraction speed of the corrugated expansion piece, and the discharge port is prevented from being closed too fast.

Atomizing nozzle adopts agricultural standard shower nozzle accessory in this embodiment, and convenient different occasions are changed and are used, and atomizing volume scattering angle isoparametric is the same with common atomizer.

Example 2
