Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of foam pumps, in particular to a foldable spring all-plastic foam pump. Background Art
[0002] The most common foam pumps on the market today are metered-dose press pumps, commonly used as dispensers in the daily chemical industry. They are suitable for products such as facial cleansing mousse, shower gel, and hand soap. They are widely used, easy to use, and popular among the general public. However, most foam pumps on the market today have an internal spring structure. When the liquid is squeezed out, the spring comes into direct contact with the liquid, causing contamination and affecting consumer use. Furthermore, the internal spring foam pumps currently on the market all use glass beads as one-way seals within the pump body. Glass beads react chemically with certain liquids, causing contamination, which also affects consumer use, especially for those with skin allergies.
[0003] According to the announcement number: "CN220375245U", this all-plastic foam pump includes a pump body, an upper piston and a piston rod. The upper part of the pump body is connected to the upper piston, and the upper part of the upper piston is connected to a fixed network. A piston rod is provided inside the pump body, and a valve needle is provided inside the piston rod. The end of the valve needle is sleeved with a lower piston, and the piston rod is placed at the bottom of the inner cavity. The piston rod is sleeved with an inherent spring. The beneficial effects of the utility model are: the pump body is arranged into an inner cavity and an outer cavity, so that the air in the pump body can be fully discharged and mixed with the liquid to produce rich and delicate foam. The spring is made of PP plastic for easy recycling. The wear of the spring is reduced by setting a spring pad to increase the service life of the pump body. In addition, the setting of the elastic valve and the spring pad can increase the sealing performance.
[0004] However, in actual use, the foaming pump may not produce foam after being used for a long time. The existing foam pump is not easy to replace, and impurities are easily introduced into the internal pump head when not in use. Therefore, improvements have been made based on the above problems.
