Description

Technical Field

[0001] This utility model relates to the field of cosmetics, and in particular to a cosmetic bottle with adjustable liquid dispensing capacity. Background Technology

[0002] Consumers often need to adjust the amount of cosmetics such as serums and lotions of varying viscosities based on factors like skin type and season. However, existing fixed-dispensing designs cannot meet personalized needs. Excessive dispensing not only wastes product but also increases the risk of contamination due to frequent refilling. Some adjustable-dispensing cosmetic bottles use multi-stage rotating latches or piston-limiting structures. Complex adjustment mechanisms can lead to a stiff pressing feel and even problems like jamming and leakage after long-term use. For example, patent CN215837565U discloses a cosmetic bottle with controllable dispensing. This device, which uses a mechanical structure to limit the pressing distance, has the following drawbacks: the structure is complex, and the limiting mechanism is easily damaged by strong pressing. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention aims to provide a cosmetic bottle with adjustable dispensing capacity, solving the problems present in the prior art. By rotating an adjusting ring that engages with the first thread of the pump housing, the maximum stroke of the piston is altered. The deeper the adjusting ring is screwed in, the earlier the piston's upward movement is obstructed, reducing the effective volume of the pump's internal cavity. This change in piston stroke maintains a consistent pressing feel. Furthermore, the force-bearing mechanism during pressing is the same as that of a traditional lotion pump, not an adjusting mechanism, ensuring that the lifespan of this cosmetic bottle is essentially no different from that of a regular cosmetic bottle.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cosmetic bottle with adjustable liquid output, comprising a bottle body, a pump body fixed inside the bottle body, and an adjusting ring threadedly connected to the pump body;

[0007] The pump body includes a pump casing, a first blocking ball installed at the lower end of the pump casing, a spring fixed at the upper end of the first blocking ball, a piston installed at the upper end of the spring, a second blocking ball installed inside the piston, and an outlet pipe fixed at the upper end of the piston.

[0008] Preferably, the upper end of the pump casing is provided with a first thread, and the lower end of the first thread is provided with a fastening ring.

[0009] Preferably, a limit ring is provided at the upper end of the piston, and a first trapezoidal plate is provided on the inner circumference of the piston.

[0010] Preferably, a limit block is provided in the middle of the outlet pipe, and a second trapezoidal plate is provided inside the outlet pipe.

[0011] (III) Beneficial Effects

[0012] This adjustable-dispensing cosmetic bottle uses a simple structure where a rotating adjustment ring engages with the threaded pump housing to precisely adjust the maximum stroke of the piston, thereby changing the effective volume of the pump's internal cavity. This meets the personalized needs of different skin types and seasons for the amount of cosmetics used, reducing waste at the source. The pressing feel is not affected during adjustment, and the pressing force is based on the traditional lotion pump mechanism, avoiding direct force loss on the adjustment structure. This ensures that the device's service life is no different from that of ordinary cosmetic bottles, while avoiding the drawbacks of complex adjustment mechanisms that are prone to jamming and damage.

Detailed Implementation

[0019] The following will refer to the appendix in the example of this utility model. Figure 1 -Appendix Figure 5 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1As shown, this utility model provides a technical solution: a cosmetic bottle with adjustable liquid output, including a bottle body 1, a pump body 2 fixed inside the bottle body 1, and an adjusting ring 3 threadedly connected to the pump body 2; the bottle body 1 serves as a storage container for cosmetics, providing liquid storage space. The pump body 2 realizes the functions of liquid extraction, compression, and discharge, and is the core actuator of the adjustment system. The adjusting ring 3 changes the maximum stroke of the piston 204 by rotating the adjusting ring, thereby controlling the internal volume of the pump body 2.

[0021] like Figure 2 As shown, the pump body 2 includes a pump housing 201, a first blocking ball 202 installed at the lower end of the pump housing 201, a spring 203 fixed at the upper end of the first blocking ball 202, a piston 204 installed at the upper end of the spring 203, a second blocking ball 205 installed inside the piston 204, and a liquid outlet pipe 206 fixed at the upper end of the piston. The pump housing 201 serves as the main frame of the pump body 2, supporting the internal mechanical structure and cooperating with the adjusting ring 3 to achieve stroke adjustment. The first blocking ball 202 is used to control the unidirectional entry of liquid into the pump body 2. The spring 203 is used to reset the piston 204. The piston 204 changes the internal cavity volume of the pump body by moving up and down. When the volume decreases, the cosmetic liquid is forced out through the second blocking ball 205 and the liquid outlet pipe 206. When the volume increases, the cosmetic liquid enters the pump body 2 through the first blocking ball 202.

[0022] like Figure 3 As shown, the pump housing 201 has a first thread 2011 at its upper end and a fastening ring 2012 at its lower end. The first thread 2011 is used to cooperate with the adjusting ring 2041 to control the liquid output of the cosmetic bottle. The fastening ring 2012 is used to insert the pump housing 201 into the bottle body 1 to achieve sealing and installation with the bottle body 1.

[0023] like Figure 4 As shown, a limit ring 2041 is provided at the upper end of the piston 204, and a first trapezoidal plate 2042 is provided on the inner circumference of the piston 204; the adjusting ring 3 cooperates with the limit ring 2041 to adjust the position of the piston 204, and the first trapezoidal plate 2042 is used to restrict the first blocking ball 202.

[0024] like Figure 5 As shown, a limiting block 2061 is provided in the middle of the outlet pipe 206, and a second trapezoidal plate 2062 is provided inside the outlet pipe 206; the limiting block 2061 is used to limit the outlet pipe 206 when it is inserted into the piston 204, to prevent the outlet pipe 206 from falling into the piston 204 when pressed, and the second trapezoidal plate 2062 is used to limit the position of the second blocking ball 205.

[0025] Working principle:

[0026] The adjusting ring 3 is threadedly connected to the pump body 2 via the first thread 2011 at the upper end of the pump housing 201. When the adjusting ring 3 is rotated, the deeper it is screwed in, the earlier the lower end of the adjusting ring 3 contacts the adjusting ring 2041 at the upper end of the piston 204, limiting the maximum upward stroke of the piston 204 and thus reducing the effective volume of the pump body cavity. The shallower the adjusting ring is screwed out, the greater the upward stroke of the piston 204, the greater the volume of the pump body cavity, and the greater the single-pass liquid output. When the liquid outlet pipe 206 is pressed, the piston 204 compresses the spring 203 downward, and the cosmetic liquid in the pump body 2 pushes open the second blocking ball 205 and is squeezed out. Then, the spring 203 pushes the piston 204 out, at which point the cosmetic liquid in the bottle 1 pushes open the first blocking ball 202 and enters the pump body 2, thus creating a cycle.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
