Description

Technical Field

[0001] This application relates to the field of perfume devices, and in particular to a liquid dispensing device. Background Technology

[0002] Perfume is a product made by dissolving fragrances in ethanol, sometimes with the addition of trace amounts of pigments, antioxidants, bactericides, glycerin, surfactants, and other additives as needed. It has a rich and fragrant aroma and is mainly used by spraying it on clothing, handkerchiefs, and hair to emit a pleasant scent. It is an important cosmetic. Simply put, perfumes, fragrances, and perfume essences are all volatile substances; they possess a certain aroma and fragrance that can be perceived by people's sense of smell or taste; they aim to please, bring spiritual pleasure, and enrich and beautify people's material culture and lives.

[0003] However, most existing perfume bottles use a manual pressing method to spray liquid, but because manual operation cannot accurately control the amount of liquid sprayed at one time, it cannot meet the personalized needs of users. Summary of the Invention

[0004] Therefore, it is necessary to provide a liquid dispensing device to address the problems mentioned above, such as the inability of existing perfume bottles to accurately control the amount of liquid sprayed per application and their inability to meet users' personalized needs.

[0005] A liquid dispensing device includes: a housing assembly having a first space inside, the housing assembly having a liquid outlet communicating with the first space; and a dispensing bottle body including a nozzle assembly and a main housing, both located within the first space. The nozzle assembly is disposed on the main housing, with one end of the nozzle assembly away from the main housing abutting against the housing assembly. The nozzle assembly is reciprocating relative to the main housing. A liquid storage chamber is formed inside the main housing for storing liquid, and the nozzle assembly is used to discharge the liquid from the liquid storage chamber. The system includes: a filling valve, which is disposed on the main body housing and has at least open and closed states. When the filling valve is in the open state, the liquid storage chamber is connected to the external atmosphere through the filling valve; when the filling valve is in the closed state, the liquid storage chamber is blocked from the external atmosphere. A lifting drive device is located within the first space. One end of the lifting drive device is connected to the housing assembly, and the other end is connected to the filling valve or the main body housing. The lifting drive device is used to drive the nozzle assembly to reciprocate relative to the main body housing.

[0006] The liquid dispensing device disclosed in this application forms a first space within a housing assembly for mounting the dispensing bottle body and a lifting drive device. The dispensing bottle body includes a nozzle assembly and a main housing. The nozzle assembly can reciprocate with the main housing. One end of the nozzle assembly abuts against the housing assembly, and one end of the main housing abuts against one end of the lifting drive device. When the lifting drive device is working, it pushes the main housing to move relative to the nozzle assembly, which is equivalent to manually pressing the nozzle, and the liquid in the liquid storage chamber is sprayed out through the nozzle assembly. By adjusting the operating parameters of the lifting drive device, such as changing the extension and retraction of the electric telescopic motor, the displacement of the nozzle assembly relative to the main body housing is changed, thereby altering the amount of liquid discharged by the liquid dispensing device per cycle. Furthermore, the dispensing bottle body is equipped with a filling valve, which enables rapid filling, improving the utilization rate of the dispensing bottle body and avoiding resource waste. Through the cooperation of the housing assembly, the dispensing bottle body, the lifting drive device, and the filling valve, the liquid dispensing device of this application can achieve electric spraying, eliminating the need for manual pressing during use. The amount of liquid discharged by the nozzle assembly per cycle can also be controlled by controlling the lifting drive device, making it particularly suitable for fields such as perfumes.

[0020] In the above embodiments, the filling valve is further defined as including a spring member, with one end of the spring member connected to the filling column and the other end connected to the main body housing. When the filling column moves from the second position to the first position, the spring member is compressed and has elastic potential energy. After filling is completed, the filling column is pushed from the first position back to the second position under the action of the spring member.
