What is the effect of the pump structure on the spraying effect of the fine mist sprayer

The operating principle of the pump body mainly relies on the manual pressing mechanism to drive the piston to move in the closed cavity, thereby realizing the alternating switching of instantaneous negative pressure and positive pressure. This process allows the liquid to be sucked in and atomized at high speed through the nozzle. The volume of the pump chamber directly affects the amount of liquid absorbed and sprayed per unit time. A pump body with a smaller volume can quickly establish high pressure, thereby achieving a delicate and fast atomization effect, which is particularly suitable for application scenarios with extremely high requirements for spray particles. A pump body with a larger volume is more suitable for use environments with a larger spray volume requirement.

The influence of the internal geometric design of the pump body on the liquid flow path cannot be ignored. Reasonable fluid dynamic structure design can effectively reduce resistance loss, improve liquid delivery efficiency, and ensure the consistency and continuity of the atomization effect. The layout of the diversion system inside the pump body directly determines the path and efficiency of pressure transmission. High-performance Fine Mist Sprayer pump bodies usually adopt multi-layer channels or spiral diversion structures, which are designed to transport liquid from the suction tube to the nozzle with the shortest path and minimum resistance, and complete pressure conversion and injection in an instant. In this process, changes in liquid flow rate and pressure have a significant impact on the atomized particle size. If the flow path is too long or unreasonable, it is easy to cause pressure loss and liquid reflux, which will cause uneven spraying or nozzle dripping, seriously affecting the spraying effect.

The valve system is an indispensable control component in the pump structure, usually including a one-way inlet valve and an outlet control valve, which are used to adjust the inlet and outlet of the liquid and maintain pressure. High-quality sprayers mostly use ball valves or soft film valve structures, which can achieve rapid opening and closing of liquid flow in a very short time, ensuring that each press operation can obtain stable atomization output. The response speed of the valve is closely related to the frequency and continuity of the spray, especially in high-frequency spray application scenarios, the technical performance of the valve is particularly important. If the valve responds laggingly or seals poorly, it is easy to cause liquid backflow or unstable spraying, thus affecting the overall user experience.

The sealing structure is crucial in maintaining the internal pressure of the pump body. The design of various sealing rings between the pump body and the nozzle, the pump body and the straw, and the pump body and the bottle mouth determines the air tightness and liquid tightness of the entire system. High-precision seals can not only effectively prevent liquid leakage, but more importantly, prevent air from infiltrating, thereby disrupting the balance of spray pressure. High-end Fine Mist Sprayer products generally adopt a multi-layer sealing design, including O-rings, U-rings and other forms to improve the reliability of the seal. Poor sealing performance will cause liquid residue or bubbles to form at the front end of the nozzle, which will make the spray particle size larger or uneven, affecting the consistency of atomization and the user experience.
