a burette assembly, includes the burette, its characterized in that: the upper portion of the dropper is sleeved with an inner stop detachably connected with the container, the dropper and the inner stop enclose a cavity for caching solution, a liquid outlet hole used for communicating an outlet of the container with the cavity is formed in the middle of the inner stop, and a liquid dropping hole communicated with the cavity is formed in the lower end of the dropper.

Furthermore, the aperture of the liquid dripping hole is 0.8-2.5 times of the aperture of the liquid outlet hole.

Furthermore, a first sealing ring matched with the inner circle sealing surface of the dropper is arranged on the inner cam.

Preferably, a third sealing ring matched with the inner circle sealing surface of the inner cam is arranged on the outer side of the dropper.

Furthermore, a second sealing ring matched with the inner side of the outlet of the container is arranged on the inner stop.

Furthermore, a buckling ring matched with the screw teeth on the outer side of the outlet of the container is arranged on the inner cam.

Furthermore, the inner part and the dropper are made of plastic, rubber and silica gel.

The beneficial effects of the above technical scheme are: the dropper is sleeved with an inner cam, one side of the inner cam, which is far away from the dropper, is sleeved at the outlet of the container, the dropper and the inner cam enclose a cavity for caching solution, the middle part of the inner cam is provided with a liquid outlet hole for communicating the cavity with the outlet of the container, and the lower end of the dropper is provided with a liquid dropping hole communicated with the cavity. And (3) squeezing the container by hand, allowing the cosmetic solution to enter the containing cavity from the container through the liquid outlet hole, continuously squeezing the container, and dripping the cosmetic solution in the containing cavity onto the cosmetic cotton through the liquid dripping hole. By adopting the dropper component in the technical scheme, the solution in the container can be quantitatively and slowly dripped in a water-drop shape, so that on one hand, a user can well control the dripping amount of the solution and avoid waste; on the other hand, the solution can not be splashed onto clothes, and the use experience of consumers is promoted.

Detailed Description

The structure of a dropper assembly according to the present invention will be described in detail with reference to the preferred embodiments and the accompanying drawings.

Referring to fig. 1 to 5, in an embodiment of the present invention, a dropper assembly 3 has an overall structure as follows: including interior zhi 1 and burette 2, interior zhi 1 is the connecting piece between container 4 and the burette 2, and interior zhi 1 suit is on burette 2 upper portion, and one side suit that interior zhi 1 deviates from burette 2 is in the outside of container 4 export, and forms detachable with container 4 and be connected. The dropper 2 and the inner cam 1 enclose a cavity 31 for caching solution, the middle part of the inner cam 1 is provided with a liquid outlet hole 14 for communicating the cavity 31 with an outlet of the container 4, and the lower end of the dropper 2 is provided with a liquid dropping hole 21 communicated with the cavity 31. The container 4 is squeezed by hand, the cosmetic solution enters the cavity 31 from the container 4 through the liquid outlet hole 14, the container 4 is squeezed continuously, and the cosmetic solution in the cavity 31 is dripped onto the cosmetic cotton through the liquid dripping hole 21.

The concrete structure is as follows:

the aperture of the liquid dropping hole 21 is 0.8-2.5 times of the aperture of the liquid outlet hole 14, when the container 4 is not squeezed, the aperture of the liquid outlet hole 14 is small and is influenced by atmospheric pressure, the cosmetic solution in the container 4 cannot enter the accommodating cavity 31, and the dropper assembly 3 has a leakage-proof function. The drip holes 21 and the liquid outlet holes 14 are arranged in proportion, so that when the container 4 is squeezed, the cosmetic solution can quickly flow into the cavity 31 and drip on the cotton pads in a water drop shape through the drip holes 21. By the arrangement, the solution can be prevented from being linearly sprayed out, and a user can determine the using amount of the solution according to the number of water drops of the solution dropping on the cosmetic cotton, so that the waste caused by excessive use of the cosmetic solution is prevented.

The inner stopper 1 is provided with a first sealing ring 11 matched with an inner circle sealing surface 23 of the dropper 2, the outer side of the dropper 2 is provided with a third sealing ring 22 matched with an inner circle sealing surface 15 of the inner stopper 1, the dropper 2 and the inner stopper 1 are in interference fit, the inner side and the outer side of the dropper 2 are simultaneously sealed through the first sealing ring 11 and the third sealing ring 22, and the solution in the cavity 31 is prevented from permeating into a gap between the dropper 2 and a contact part of the inner stopper 1.

The inner stopper 1 is provided with a second sealing ring 12 matched with the inner side of the outlet of the container 4, and the contact part of the inner stopper 1 and the inner side of the outlet of the container 4 is sealed through the second sealing ring 12, so that the solution in the container 4 is prevented from seeping out from the contact part of the inner stopper 1 and the outlet of the container 4.

The inner stopper 1 is provided with a buckling ring 13 matched with the thread outside the outlet of the container 4, and the inner stopper 1 and the container 4 are tightly connected together by tightly buckling the buckling ring 13 and the thread buckling line on the container 4, so that the dropper assembly 3 is prevented from flying out due to stress in the process of squeezing the container 4 by a user.

The inner cam 1, the dropper 2 and the container 4 are made of plastic, rubber and silica gel, and in the embodiment, the inner cam 1, the container 4 and the dropper 2 are made of plastic and have elasticity.

By adopting the dropper component 3 in the technical scheme, the solution in the container 4 can be quantitatively and slowly dripped in a water-drop shape, so that on one hand, a user can well control the dripping amount of the solution and avoid waste; on the other hand, the solution can not be splashed onto clothes, and the use experience of consumers is promoted.

While the above detailed description describes the preferred embodiment of the present invention, it is not intended to limit the scope of the present invention, but rather, the present invention is intended to cover by those skilled in the art all such modifications and equivalents as may be included within the spirit and scope of the present invention.
