[0002] A dropper is one of the commonly used tools for using cosmetics. A dropper usually includes a straw and an elastic rubber head. In order to avoid mutual contamination between cosmetics, the dropper usually needs to be cleaned after using one cosmetic before it can be put into another cosmetic. For cosmetics that are used in very small amounts, this is quite troublesome and will undoubtedly increase the makeup time. Summary of the invention

[0003] The purpose of the present application is to provide a double-liquid cosmetic dropper that is more convenient to use.

[0004] To achieve the above purpose, the present application provides a double-liquid cosmetic dropper: comprising an elastic bag and a pipette that are internally connected, the pipette comprising a pair of branch tubes, each of the branch tubes having a liquid storage cavity that passes through the lower end, the upper ends of the two liquid storage cavities being connected, a clamping assembly being arranged outside the two branch tubes, the clamping assembly comprising a bridge plate located between the two branch tubes, the four corners of the bridge plate being movably connected to clamping rods, the end of each clamping rod away from the bridge plate being movably connected to a connecting sleeve, the two connecting sleeves distributed on both sides of the same branch tube are brought closer or farther away through a bolting member, thereby realizing the clamping or releasing action of the branch tube.

[0006] Preferably, the connection plate is provided with a convection hole which passes through from top to bottom, and the convection hole connects the inside of the elastic bag and the connecting cavity, so that the internal air pressure of the elastic bag can act on the branch pipe.

[0007] As a preference, the upper end of the branch pipe is large and the lower end is small, and the lower end of the branch pipe is fixedly connected with a tube cone for replacing the branch pipe and sinking into the cosmetic liquid.

[0008] As a preference, the elastic bag and the branch tube are made of silicone material, the connecting plate and the tube cone are made of plastic material, the parts that need to be deformed are made of soft material, and the parts that do not need to be deformed are made of hard material.

[0009] Preferably, the clamping rod is hinged to the bridging plate, the hinge axis is parallel to the extension direction of the branch pipe, and the clamping rod swings in a direction perpendicular to the branch pipe.

[0010] As a preferred embodiment, the two clamping rods located on both sides of the same branch pipe are hinged with a first connecting sleeve and a second connecting sleeve at their ends, respectively, and the hinge axis is parallel to the extension direction of the branch pipe. The bolting member is suitable for connecting the first connecting sleeve and the second connecting sleeve to achieve clamping and releasing actions.

DETAILED DESCRIPTION

[0022] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0024] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0025] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0026] like Figure 1-6The double-liquid cosmetic dropper shown includes an elastic capsule 1 and a liquid pipette 2 which are internally connected. In this embodiment, the elastic capsule 1 is ellipsoidal and made of silicone material. The liquid pipette 2 has a bifurcated structure, including a pair of branch tubes 202. The interior of each branch tube 202 has a liquid storage cavity 203 that passes through the lower end and can store cosmetic liquid. The upper ends of the two liquid storage cavities 203 are connected, which is actually connected to the interior of the elastic capsule 1. Specifically: the upper ends of the two branch tubes 202 are fixedly connected with a connecting disk 201, and the connecting disk 201 is made of hard plastic. A connecting cavity 204 is formed between the bottom of the connecting disk 201 and the inner walls of the two branch tubes 202. The connecting cavity 204 connects the two liquid storage cavities 203. The connecting disk 201 is provided with a convection hole 205 that passes through from top to bottom. The convection hole 205 connects the interior of the elastic capsule 1 and the connecting cavity 204, so that air pressure can be transmitted between the cavities.

[0027] The upper end of the branch tube 202 is large and the lower end is small, forming an inverted cone. The branch tube 202 is also made of silicone material. The lower end of the branch tube 202 is fixedly connected with a tube cone 3. The outer diameter of the tube cone 3 is significantly smaller than the outer diameter of the branch tube 202. The tube cone 3 is made of hard plastic. In order to further ensure the safety of the use of cosmetics, the elastic capsule 1 and the branch tube 202 are usually made of food-grade silicone material, and the plastic used for the connecting plate 201 and the tube cone 3 is usually PET material.

[0028] A clamping assembly 4 is provided outside the two branch pipes 202 for clamping and compressing the branch pipes 202 so that the fluid inside them loses the ability to flow. The clamping assembly 4 includes a bridging plate 401 located between the two branch pipes 202. The four corners of the bridging plate 401 are movably connected with clamping rods 402 respectively. The clamping rods 402 are hinged to the bridging plate 401, and the hinge axis is parallel to the extension direction of the branch pipes 202. That is to say, each clamping rod 402 can rotate on a plane parallel to the bridging plate 401.

[0029] The end of each clamping rod 402 away from the bridging plate 401 is movably connected with a connecting sleeve, and the two connecting sleeves distributed on both sides of the same branch pipe 202 are brought closer or farther away through the bolting piece 450. Specifically: the two clamping rods 402 located on both sides of the same branch pipe 202 are respectively hinged with a first connecting sleeve 403 and a second connecting sleeve 404 at the ends, and the structures of the two connecting sleeves are actually the same, but one of the connecting sleeves needs to be additionally connected to other components. The hinge axes of the two connecting sleeves are parallel to the extension direction of the branch pipe 202, which means that the connecting sleeves can swing on the same horizontal plane with the clamping rod 402. After the connecting sleeves have this degree of freedom, they will not be restricted by the angle of the clamping rod 402 when approaching each other. The bolting piece 450 is used to connect the first connecting sleeve 403 and the second connecting sleeve 404 to achieve the mutual approach of the two. Or away from each other, the specific structure of the bolting member 450 includes a screw rod 451, one end of which is fixedly connected to a limiting ring 452. The diameter of the limiting ring 452 is significantly larger than that of the screw rod 451 and is used to limit the position of one end of the screw rod 451. The end face of the limiting ring 452 is provided with a handle 453. The screw rod 451 can be rotated relatively easily by pinching the handle 453. The handle 453 is provided with a hanging hole 454 that passes through the side surface. The handle 453 can be rotated by passing a rod through the hanging hole 454, which will be more labor-saving. The end of the second connecting sleeve 404 that is back to the first connecting sleeve 403 is fixedly connected with a nut 405. The screw rod 451 passes through the first connecting sleeve 403 and the second connecting sleeve 404 in turn and is threadedly connected to the nut 405, thereby converting the rotational motion of the bolting member 450 into relative movement of the first connecting sleeve 403 and the second connecting sleeve 404.

[0030] Working principle: the cosmetic dropper has two usage states. One is to remove the clamping component 4 so that the two branch tubes 202 can absorb and discharge liquid at the same time; the other is that a group of clamping rods 402 of the clamping component 4 clamp one branch tube 202, and the other is in a free state. By squeezing the elastic capsule 1, the branch tube 202 in the free state can absorb and discharge liquid, and the clamped branch tube 202 will not have the above-mentioned actions even if it is immersed in liquid. After one branch tube 202 absorbs liquid, it only needs to wipe off the cosmetic liquid stuck on the outer surface of the branch tube 202, and then use another group of clamping rods 402 to clamp it, and then release the other branch tube 202, put it in another cosmetic, press the elastic capsule 1 again, and the other elastic capsule 1 can also absorb and discharge liquid. The front branch tube 202 will not absorb the cosmetic liquid even if it is immersed in liquid, so the dropper can operate on two cosmetic liquids.
