Description

Technical Field

[0001] The present invention relates to an emulsion bottle combined with a spraying function, which is a dual-functional cosmetic bottle. Background Art

[0002] An emulsion bottle refers to a micro-sprayer that causes a liquid cream cosmetic (emulsion) to flow out of a container by pressing the nozzle of an emulsion pump. Its working principle is that by reciprocally pressing the nozzle, the volume inside the bottle periodically increases and decreases, increasing the pressure of the liquid, thereby sucking and discharging the liquid inside the bottle. A micro-sprayer generally refers to a cosmetic bottle that atomizes and sprays a liquid cosmetic (such as perfume) from a container by pressing the nozzle of the sprayer. Its working principle is that through reciprocally pressing operations by hand, the piston moves in the pump body, causing the gas inside the pump body to flow, reducing the pressure, the pressure outside the pump body remains unchanged, a pressure difference is generated inside and outside the pump body, and the liquid is guided out of the pump body through the pressure difference. When the liquid encounters a high-speed airflow, it is blocked and instantly atomized and sprayed. Therefore, the density requirements for the liquid are different for the two, and there is less combination of the two. For example, in the Chinese patent document with the authorized publication number CN201942101U, the authorized publication date is August 24, 2011, and the utility model name is "-A pump body structure that can be used as an emulsion pump or a spray pump"; the pump core assembly of this structure is provided with an emulsion nozzle or a spray nozzle. The top of the button of the spray nozzle is provided with a rubber plug, and at the same time, there are mist points on one side. However, the above products and similar products are relatively inconvenient to use. The nozzle needs to be replaced to be used and cannot be directly rotated for use. Summary of the Invention

[0003] To overcome the above deficiencies, the purpose of the present invention is to provide a dual-functional cosmetic bottle to the art, so as to solve the technical problems that the switching between emulsion and spray operations of existing similar products is relatively inconvenient and the assembly and production are relatively inconvenient. Its purpose is achieved through the following technical solutions.

[0004] A dual-functional cosmetic bottle, in which a pump core assembly is provided inside a large circle of the cosmetic bottle, and the valve rod of the pump core assembly is connected to a head cap through a fixing sleeve; the key point of the structural design is that the inner diameter of the bottom of the fixing sleeve is provided with a positioning groove, and the outer diameter of the inner sleeve opening protruding from the inner side of the top of the large circle is provided with a positioning rib. When the positioning groove of the fixing sleeve is sleeved and fixed on the positioning rib of the large circle, the central hole at the bottom of the fixing sleeve is sleeved with the valve rod of the pump core assembly, and a rubber cover is sleeved on the boss at the top of the fixing sleeve. The rubber cover is provided with a cover spray hole and a cover lotion hole, and the head cap is provided with a cap spray hole and a cap lotion hole.
