A non-clogging atomizing nozzle under normal pressure

Abstract

The invention discloses a normal-pressure unblocked atomization nozzle. The normal-pressure unblocked atomization nozzle comprises a nozzle housing, an atomization spray sheet and a flow guide stopper core, wherein a nozzle opening is formed in a first end of the nozzle housing; the atomization spray sheet is provided with at least one spray hole; the flow guide stopper core comprises two end surfaces and a side circumferential surface of a column body; a plurality of flow guide grooves are formed in the side circumferential surface of the flow guide stopper core; the first end surface of the flow guide stopper core is provided with a plurality of flow guide blocks in a manner of being close to the edge of the flow guide stopper core; the two adjacent flow guide blocks are spaced by a certain distance to form a flow guide channel; the inner sides of the flow guide blocks together define a swirl groove; the flow guide block on the first end surface of the flow guide stopper core props against a second surface of the atomization spray sheet; and the swirl groove corresponds to the spray holes in position. According to the normal-pressure unblocked atomization nozzle, a liquid can form swirl flow in the swirl groove, so that the flowability of the liquid can be enhanced, the flow velocity of the liquid can be increased, the atomization effect of the liquid can be well improved, the liquid does not need to be pressurized, and a very good atomization effect can be achieved even under the normal pressure.

Description

technical field [0001] The invention relates to the technical field of spray devices, in particular to a normal pressure non-blocking atomizing nozzle. Background technique [0002] Nozzle is a key component in many kinds of spraying, spraying, oil spraying, sandblasting, spraying and other equipment, and plays an important role. In order to ensure the spray effect of the nozzle, the nozzle of each nozzle is carefully carved. Even injuries caused by improper cleaning can affect flow and spray distribution. [0003] The nozzles in the prior art also have the following defects: [0004] 1. The atomization effect is poor, and the liquid sprayed from the nozzle cannot be spread well, which affects the spray effect; [0005] 2. In the prior art, in order to enhance the atomization effect, the liquid is usually pressurized, which will increase the difficulty of the spray operation, the operation is complicated, and the overall structure of the spray device is complicated; [0...

AI Technical Summary

Problems solved by technology

[0004] 1. The atomization effect is poor, and the liquid sprayed from the nozzle cannot be well diffused, which affects the spray effect;

[0005] 2. In the prior art, in order to enhance the atomization effect, the liquid is usually pressurized, which will increase the difficulty of the spraying operation, the operation is complicated, and the structure of the overall spraying device is complicated;

[0006] 3. The nozzles in the prior art are prone to clogging, and once they are clogged, the spraying effect will be affected, and even the liquid cannot be sprayed, thus affecting the spraying operation
