Description

Technical Field

[0001] This utility model relates to the field of emulsion spray nozzle technology, specifically a vacuum self-priming emulsion spray nozzle. Background Technology

[0002] Lotion is a liquid cosmetic or skin care product. It has a light texture, between toner and cream, and is semi-fluid, making it easy to spread on the skin. The lotion spray nozzle is an important component used to dispense lotion from a lotion storage bottle.

[0003] Existing emulsion spray nozzles typically have components integrated and fixed together, making it impossible to disassemble each component. The joints between components are prone to emulsion residue and bacterial growth, making cleaning inconvenient and preventing reuse, which is not energy-saving or environmentally friendly. In addition, when the emulsion is left for a long time, the lack of a mixing mechanism inside the emulsion spray nozzle makes it impossible to ensure the accurate and uniform composition of the emulsion each time it is used, resulting in poor product performance. To address these issues, we have proposed a vacuum self-priming emulsion spray nozzle. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum self-priming emulsion spray nozzle to solve the problems mentioned in the background art. In existing emulsion spray nozzles, the components are usually integrated and fixed together, making it impossible to disassemble each component. The joints between the components are prone to emulsion residue and bacterial growth, making cleaning inconvenient. Furthermore, the nozzle cannot be reused, which is not conducive to energy conservation and environmental protection. At the same time, when the emulsion is left for a long time, the lack of a mixing mechanism inside the emulsion spray nozzle makes it impossible to ensure the accurate and uniform composition of the emulsion each time it is used, resulting in poor product performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum self-priming emulsion nozzle, comprising a vacuum tube, a connector, a connecting tube, and a cap. The connector is snapped onto the upper side of the outer wall of the vacuum tube. The connecting tube movably passes through the top center of the connector and extends into the inner cavity of the vacuum tube. The cap is located on the outer side of the connecting tube.
