Description

Technical Field

[0001] This invention relates to the field of pump head technology, specifically to a pump head structure for daily chemical products with adjustable liquid output. Background Technology

[0002] Daily chemical products refer to consumer products used in daily life that are mainly composed of chemically synthesized or natural ingredients, covering multiple fields such as personal care, household cleaning, and beauty and hair care. Pump heads are common actuators in the packaging of daily chemical products, used for pumping out the products.

[0003] Chinese patent discloses a novel pump head for daily chemical detergents (authorization announcement number CN207129375U). This patented technology seals the hydraulic chamber through a pressure-operating piston and a thin-walled skirt-shaped sealing ring on a fixing ring, while simultaneously assembling the hydraulic cylinder assembly onto the bottle cap. An upper valve core blocking ring is installed in the inner hole of the pressure-operating piston to block the upper valve core at the lower end of the piston and maintain it in the same position. Forced demolding is used for ejection from the plastic molding die, simplifying mold manufacturing. During assembly, a press-fitting machine is used to press it in through piston deformation. This technology has wide applications. When used in the packaging of daily chemical products, this pump head is economical and practical, reducing assembly workload and significantly saving materials and labor time, making it worthy of promotion. However, impurities in the pumped material affect its effectiveness, and prolonged use can easily cause blockage at the outlet, hindering smooth pumping operation.
