The relationship between service life and structural design
As an important component responsible for delivering liquid in a spray bottle, the structure of the treatment pump is usually composed of a pump core, a spring, a piston, a straw and a nozzle. These components need to maintain coordinated movements during repeated pressing to achieve stable liquid discharge. After long-term use, wear or deformation of any part may affect the sealing or liquid discharge efficiency, resulting in problems such as leakage or blockage.
Common aging phenomena include weakened spring elasticity, unsmooth piston return, loose seals, and micropore fouling of the nozzle. These problems are often the root cause of poor use, rather than defects in a single component.

Main causes of leakage problems
The leakage of the treatment pump is usually related to the following aspects:
1. Fatigue of the sealing structure. If the sealing ring inside the pump head is corroded by liquid for a long time or frequently mechanically compressed, it will gradually lose its elasticity, causing the liquid to seep out of the gap in the pump head when it is stationary or pressed.
2. Liquid viscosity and corrosiveness. Some liquids with more active ingredients, such as high-concentration alcohol or essence liquids with strong oil content, may cause some plastic materials to deform slightly or crack if they are in contact with the pump body for a long time, affecting the sealing performance.
3. The connection between the bottle mouth and the pump head is not tight. If the tightening method is not in place or the bottle mouth size tolerance is large, slow leakage may occur at the connection under gravity, tilting or repeated use.

Common causes of blockage problems
The blockage problem of the pump often occurs in the nozzle, suction pipe or pump core cavity. Common reasons are as follows:
1. Liquid dries up and remains. If the bottle cap is not cleaned or tightly closed in time during use, the residual liquid in the pump head may become thick and crystallized due to volatilization, and eventually block the nozzle channel.
2. There are suspended particles in the formula. Some lotions and essential oil products contain tiny particles or insoluble substances. These substances will accumulate for a long time and jam the pump core channel or nozzle mouth.
3. The suction tube is bent or bubbles accumulate. If the straw is not designed properly or the material is too soft, the suction may be affected by bending after long-term use. In addition, the bubbles in the bottle cannot be discharged smoothly, which may cause intermittent discharge or complete blockage.

Impact of frequency of use on performance
The service life of the pump head is also closely related to the frequency in practical applications. Daily household spray bottles may be pressed several times a day and used stably for a long time. In commercial scenarios, such as beauty salons, cleaning factories and other high-frequency places, the intensity of use hundreds of times a day will put higher requirements on the pump body structure.
Frequent use accelerates the wear rate, especially the sliding area of ​​the pump core and the elastic attenuation of the spring. Therefore, for users with higher frequency, it is recommended to regularly check the rebound of the pump body, the patency of the nozzle, and whether there is liquid retention, so as to predict the state of the pump head and prevent sudden failure.

Impact of material selection on performance
The material of the processing pump is directly related to its long-term stability. Common materials include PP (polypropylene), PE (polyethylene), PET (polyester), etc., and stainless steel springs or POM engineering plastics are often used in the pump core.
High temperature, ultraviolet rays, and chemical composition will affect the aging rate of materials. If the pump head is used in a complex environment, it is recommended to choose a material solution with strong corrosion resistance and better high temperature resistance to reduce the risk of leakage or blockage due to aging.

How to extend the service life of the treatment pump
In order to reduce the probability of failure of the treatment pump during long-term use, it is recommended to take the following measures:
* After each use, wipe the pump head clean to prevent liquid residue;
* After use, tighten the bottle cap or locking device to reduce air entry;
* Avoid exposing the bottle to high temperature or direct sunlight for a long time;
* Regularly clean the pump head with warm water, especially the nozzle and pipe part;
* Try to choose a design with rebound lock and sealing gasket to improve sealing;
* If abnormal discharge or slow rebound is found during use, the pump head should be replaced in time.
