Its working principle is: by pressing the head cap of the sprayer, the volume of the bottle body increases and decreases periodically, increasing the pressure of the liquid, thereby sucking and draining the liquid in the bottle body. Patent application number CN202221013249.2 discloses a double-tube replaceable anti-static polymer emulsion sprayer. It is designed to address the technical problems of existing similar products, such as the lack of inner and outer caps on the head cap and the lack of a cover on the top, which makes production and assembly more inconvenient, and the need for improvement in material production and preparation. The main points are that the lotion spray head includes a large inner bottle and a small inner bottle arranged inside an outer bottle, and corresponding large and small pump core assemblies. The outer cap is sleeved on the outer diameter of the inner cap, and arc-shaped clamping columns are symmetrically provided on both sides of the center of the outer cap. The clamping columns of the outer cap are inserted into the clamping holes on both sides of the top of the inner cap. At the same time, the positioning columns of the inner cap are respectively inserted into the column holes raised in the groove at the top of the large ring. The top middle protrusion of the outer cap is provided with a center platform groove, and the bottom middle protrusion of the cover plate is provided with cover plate columns with symmetrical openings at the hole. The cover plate columns are fastened and fixed with the center platform groove of the outer cap. A sealing and fastening pressure cap is provided in one side of the bottle mouth of the large inner bottle. The large ring, large inner bottle and outer bottle are fastened together as a whole. The inner bottle replacement structure of this lotion bottle is relatively complex, its manufacturing cost is high and replacement is inconvenient. Utility Model Content
