Shower head ", they all disclose a kind of conventional shower head structure.

The existing nozzles for emulsion pumps have the following defects: the structure of the existing nozzles for emulsion pumps cannot prevent the liquid in the pump from volatilizing, resulting in reduced efficacy or functional failure of the nail polish remover. Another example is that during the use of the existing lotion nozzle, some liquid will remain at the mouth of the nozzle on the pressure cap. This part of the liquid will either drip down and stain the table, or stay at the mouth of the nozzle, and will be oxidized over time. A block is formed, and the liquid in the pump of this existing emulsion nozzle structure communicates with the outside air, which easily causes the liquid in the pump to be oxidized, deteriorated and polluted. Therefore, in order to ensure the freshness of the liquid in the pump, it is necessary to add preservatives and antioxidants to the emulsion, which makes the emulsion not natural enough and not environmentally friendly.
