Description

Technical Field

[0001] This utility model relates to the field of sprayer technology, specifically a one-way pressure relief sprayer. Background Technology

[0002] A sprayer is a device that converts liquid into a mist, primarily used in medical, agricultural, and other fields. Modern sprayers, when operated, use a lever that drives a piston rod to reciprocate under the action of a spring, drawing liquid from the bottle into a suction tube and spraying it out through a nozzle, achieving precise spraying. They offer advantages such as saving time and effort, and providing excellent atomization. However, current sprayers still have the following shortcomings:

[0003] For example, patent document CN221951471U discloses a sprayer. This sprayer adds an air duct assembly, and the airflow generated by the air duct assembly can act on the mist sprayed from the nozzle, thereby improving the uniformity of spraying. In addition, the spraying range of the sprayer varies under different working conditions, which can adapt to different usage needs. However, during use, outside air can enter the bottle through the vent, contaminating the liquid inside the bottle. Moreover, this sprayer is not airtight when the cap is closed and the lever is spring-loaded. Therefore, during the irradiation process, the liquid evaporates to produce gas and water vapor, increasing the pressure inside the bottle, which can easily lead to the bottle expanding, deforming, and breaking.

[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings and proposed a one-way pressure relief sprayer. Utility Model Content
