Description

Technical Field

[0001] This invention relates to the field of spraying device technology, specifically a portable spraying device. Background Technology

[0002] Portable sprayers are widely used in various fields such as daily chemicals, medicine, horticulture, and disinfection. They enable the atomization and spraying of liquids in scenarios without power supply, meeting the requirements for convenient and efficient use anytime, anywhere.

[0003] Traditional spray devices rely on manually pressing the pump head to move the piston downward, compressing the space inside the pump head to generate pressure, closing the water inlet valve and opening the water outlet valve, so that the liquid is sprayed out through the nozzle. After releasing, the spring returns to its original position, causing the piston to move upward, creating a negative pressure inside the pump head, opening the water inlet valve to draw in the liquid, or by shaking the pressure handle up and down or left and right to pressurize the liquid storage tank, using the air pressure to force the liquid out of the nozzle to form a mist.

[0004] However, traditional spray devices have limited spray volume per press, making it difficult to meet the needs of large-area or continuous spraying. Furthermore, the need for frequent pressing can lead to hand fatigue, resulting in uneven pressure delivery and unstable internal air pressure, which in turn causes uneven spraying. Summary of the Invention
