Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging technology, and more specifically, to a dual-pump spray head. Background Technology

[0002] In existing technologies, spray pumps are a common component of cosmetic packaging bottles. The main working principle of a spray pump is to reduce the space between the piston and the main body of the liquid container by pressing down the piston, which causes the air pressure in the liquid container to increase sharply. This forces the liquid to be squeezed out through the one-way valve of the auxiliary column. The squeezed liquid is then forced into the flow channel of the main column through the auxiliary column and sprayed out through the nozzle of the pump head. However, existing spray pumps are designed with only one cavity for holding the liquid. A spray pump with only one cavity can only hold the finished product during use. If the spray that requires mixing two liquids is directly mixed into the finished product, the product may deteriorate if stored for a long time. Therefore, a technical solution is needed to solve the above problems. Utility Model Content
