[0002] In the category of cosmetics, serums generally refer to products with a high concentration of active ingredients. During use, the high proportion of active ingredients can enhance the skincare effect for a specific purpose, allowing the skin to achieve a more noticeable skincare result.

[0003] The following issues may occur during the use of this serum:

[0004] During the serum dispensing process, the amount of serum dispensed varies depending on the pressure applied with the finger. Less pressure results in less serum being dispensed, requiring multiple presses to apply to the facial skin, while greater pressure results in more serum being dispensed, leading to waste. Therefore, this application proposes an adjustable serum dispensing head with a rotating control. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable liquid output serum rotary control applicator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable liquid output serum rotary control applicator, including a storage bottle filled with serum, a compression piston inserted into the storage bottle, and the bottom of the compression piston connected to a lifting plate via several connecting rods;

[0007] An adjusting rod is inserted inside the lifting plate. An upper limiting plate is installed on the top of the adjusting rod, and a lower limiting component is sleeved on the adjusting rod. The upper limiting plate and the lower limiting component are located on the upper and lower sides of the lifting plate, respectively.

[0008] The adjusting rod is connected to the height adjusting sleeve, which is threadedly connected to the storage bottle.

[0011] Preferably, there are three connecting rods, and the three connecting rods are arranged in a circumferential array around the center line of the compression piston.

[0012] Preferably, the side wall of the lifting plate abuts against the inner wall of the storage bottle.

[0013] Preferably, the height adjustment sleeve is connected to an outer adjustment tube, which is inserted into the adjustment bottle.

[0014] Preferably, the lower limiting member and the adjusting rod are connected by threads, the adjusting rod is fixedly connected to the central rod, the central rod is inserted into the height adjusting sleeve, and the central rod and the height adjusting sleeve can rotate relative to each other.

[0015] Preferably, the lower limiting member is inserted into the guide sleeve, and the lower limiting member is slidably connected to the guide groove in the guide sleeve.

[0016] Preferably, the lifting plate is connected to several guide rods, which are connected to the regulating bottle. There are six guide rods arranged in a circular array around the center line of the storage bottle. The guide rods pass through the bottom of the storage bottle and are slidably connected to the storage bottle. The storage bottle is retracted into the regulating bottle, and the outer wall of the storage bottle is in contact with the inner wall of the regulating bottle.

[0017] Preferably, a liquid replenishment tube is provided at the top of the storage bottle near the drain port. The liquid replenishment tube is connected to a replenishment tube. The height at which the replenishment tube is inserted into the storage bottle is lower than the height of the drain port. A one-way valve is installed inside the replenishment tube.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. When using this utility model, pressing the adjusting bottle can push the lifting plate and the compression piston to move, thereby squeezing the essence in the storage bottle and squeezing out the essence. The height adjusting sleeve is connected to the storage bottle by threads. Rotating the height adjusting sleeve can adjust the height of the adjusting rod, the upper limiting plate, the lower limiting member, and the overall height of the lifting plate. As the essence in the storage bottle is used, the liquid level in the storage bottle drops. Therefore, it is necessary to adjust the liquid level in the storage bottle regularly by using the height adjusting sleeve. When pressing, the lifting plate and the compression piston move. Under the restriction of the upper limiting plate and the lower limiting member, the lifting plate is pressed to the bottom. The movement distance is the same. Only when the lifting plate and the compression piston move the same distance can the same amount of purified liquid be pushed out of the storage bottle.

[0020] II. The rotating center rod of this utility model can drive the adjusting rod to rotate. The adjusting rod and the lower limiting member are connected by threads. The adjusting rod rotating in the forward and reverse directions can drive the lower limiting member to move up and down, thereby adjusting the distance between the upper limiting plate and the lower limiting member. This distance is the moving range of the lifting plate. The larger the moving range of the lifting plate, the more essence is squeezed out with a single press, and vice versa.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-4 An adjustable serum dispensing rotary control applicator includes a storage bottle 1 filled with serum and a cap 16. The serum is a highly concentrated skincare product, usually in liquid or water form, with a refreshing texture, easy absorption, and suitable for all skin types. A compression piston 2 is inserted into the storage bottle 1. A sealing groove is provided on the side wall of the compression piston 2, and a sealing ring is fitted into the sealing groove. The sealing ring abuts against the inner wall of the storage bottle 1 to prevent the purified liquid in the storage bottle 1 from entering below the compression piston 2 and to prevent the serum from moving below the compression piston 2 and being wasted. The bottom of the compression piston 2 is connected to a lifting plate 4 through several connecting rods 3. Specifically, there are three connecting rods 3, and the three connecting rods 3 are arranged in a circumferential array around the center line of the compression piston 2.

[0028] Specifically, an adjusting rod 5 is inserted inside the lifting plate 4, an upper limiting plate 6 is installed on the top of the adjusting rod 5, and a lower limiting member 7 is sleeved on the adjusting rod 5. The upper limiting plate 6 and the lower limiting member 7 are located on the upper and lower sides of the lifting plate 4, respectively. The side wall of the lifting plate 4 abuts against the inner wall of the storage bottle 1, and the two can slide relative to each other up and down. The side wall of the lifting plate 4 abutting against the storage bottle 1 can improve the stability of the lifting plate 4 during the up and down movement.

[0029] More specifically, the adjusting rod 5 is connected to the height adjusting sleeve 9. Specifically, the height adjusting sleeve 9 and the adjusting rod 5 can only rotate relative to each other, and the two cannot move up and down relative to each other. The height adjusting sleeve 9 is threadedly connected to the storage bottle 1. More specifically, the height adjusting sleeve 9 is connected to the outer adjusting tube 10, and the outer adjusting tube 10 is inserted into the adjusting bottle 14.

[0030] The height adjustment sleeve 9 is connected to the storage bottle 1 by a thread. Rotating the height adjustment sleeve 9 can adjust the overall height of the adjustment rod 5, the upper limiting plate 6, the lower limiting piece 7, and the lifting plate 4. As the essence in the storage bottle 1 is used, the liquid level of the essence in the storage bottle 1 decreases. Therefore, it is necessary to adjust the liquid level of the essence in the storage bottle 1 periodically by using the height adjustment sleeve 9. When pressed, the lifting plate 4 and the compression piston 2 are moved. Under the restriction of the upper limiting plate 6 and the lower limiting piece 7, the lifting plate 4 and the compression piston 2 that move the same distance can push out an equal amount of purified liquid from the storage bottle 1.

[0031] In a further embodiment, the lower limiting member 7 and the adjusting rod 5 are connected by threads. The adjusting rod 5 is fixedly connected to the central rod 12. The central rod 12 is inserted into the height adjusting sleeve 9, and the central rod 12 and the height adjusting sleeve 9 can rotate relative to each other. Rotating the central rod 12 can drive the adjusting rod 5 to rotate. The adjusting rod 5 and the lower limiting member 7 are connected by threads. The adjusting rod 5, which rotates in both directions, can drive the lower limiting member 7 to move up and down, thereby adjusting the distance between the upper limiting plate 6 and the lower limiting member 7. This distance is the moving range of the lifting plate 4. The larger the moving range of the lifting plate 4, the more essence is squeezed out with a single press, and vice versa.

[0032] Specifically, the lower limiting member 7 is inserted into the guide sleeve 8. The lower limiting member 7 is set to a shape with an inner round hole and an outer square shape. The lower limiting member 7 is slidably connected to the guide groove in the guide sleeve 8. The guide sleeve 8 restricts the lower limiting member 7 to prevent it from rotating together with the adjusting rod 5, thus preventing the adjustment of the distance between the upper limiting plate 6 and the lower limiting member 7.

[0033] In a further embodiment, the lifting plate 4 is connected to several guide rods 13, and the guide rods 13 are connected to the regulating bottle 14. Specifically, there are six guide rods 13, and the six guide rods 13 are arranged in a circular array around the center line of the storage bottle 1. The guide rods 13 penetrate the bottom of the storage bottle 1 and are slidably connected to the storage bottle 1. The storage bottle 1 is retracted into the regulating bottle 14, and the outer wall of the storage bottle 1 is in contact with the inner wall of the regulating bottle 14.

[0034] It should be noted that the lifting plate 4 and the inner wall of the bottom of the storage bottle 1 form a lower air storage chamber (the cavity surrounded by the compression piston 2 and the bottom of the storage bottle 1 is the entire air storage chamber, and the lifting plate 4 needs to have a hole connecting the upper and lower air storage chambers). The air storage chamber is connected to the vent pipe 15, which passes through the regulating bottle 14. During the up-and-down movement of the lifting plate 4, the compression piston 2 will be pushed upward. As the compression piston 2 moves upward, the air pressure at the bottom of the storage bottle 1 decreases. When the lifting plate 4 is released, the compression piston 2 will move downward under the action of the essence, air pressure, and other forces. At this time, the liquid level of the essence inside the storage bottle 1 will drop. After long-term use, the amount of essence pushed out by the lifting plate 4 after moving the same distance will gradually decrease. Therefore, the air storage chamber is connected to the outside air through the vent pipe 15.

[0035] The compression piston 2 pushes the essence forward, squeezing it out of the storage bottle 1. After the compression piston 2 is released, it recoils slightly due to the reaction force of the essence. A height difference exists between the recoiled essence level and the previous level. Therefore, a liquid replenishment tube 18 is installed at the top of the storage bottle 1 near the drain port 17. The liquid replenishment tube 18 connects to a replenishment tube, and the height of the replenishment tube inserted into the storage bottle 1 is lower than the height of the drain port 17. A one-way valve is installed inside the replenishment tube. When the essence level in the storage bottle 1 is lower than the height of the replenishment tube, the essence in the replenishment tube 18 will enter the storage bottle 1 under gravity until the essence level in the storage bottle 1 is equal to the height of the replenishment tube inserted into the storage bottle 1. A one-way valve is installed at the drain port 17, and an air inlet is also provided inside the storage bottle 1, which is also equipped with a one-way valve.

[0036] Working principle:

[0037] Pressing the regulating bottle 14 can push the lifting plate 4 and the compression piston 2 to move, thereby squeezing the essence in the storage bottle 1 and squeezing out the essence.

[0038] The height adjustment sleeve 9 is connected to the storage bottle 1 by a thread. Rotating the height adjustment sleeve 9 can adjust the overall height of the adjustment rod 5, the upper limiting plate 6, the lower limiting piece 7, and the lifting plate 4. As the essence in the storage bottle 1 is used, the liquid level of the essence in the storage bottle 1 decreases. Therefore, it is necessary to adjust the liquid level of the essence in the storage bottle 1 periodically by using the height adjustment sleeve 9. When pressed, the lifting plate 4 and the compression piston 2 are moved. Under the restriction of the upper limiting plate 6 and the lower limiting piece 7, the lifting plate 4 is pressed to the bottom. The moving distance is the same. Only when the moving distance of the lifting plate 4 and the compression piston 2 is the same can the same amount of purified liquid be pushed out of the storage bottle 1.

[0039] 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.
