Description

Technical Field

[0001] The invention relates to the field of cosmetic bottle components, and in particular to a dislocation extrusion type automatic material suction method and a dropper thereof. Background Art

[0002] In the field of cosmetic bottle components, the straw extrusion deformation method used by traditional droppers has many disadvantages. In the current common dropper structure, the straw extrusion deformation part is usually exposed. This design makes the extrusion part extremely easy to be contaminated with dust, impurities and other pollutants during use. For example, in a laboratory or makeup scene, the environment around the dropper is complex, and dust is easy to adhere to the exposed extrusion part. When the liquid is subsequently absorbed, these pollutants may enter the liquid, which will not only contaminate the liquid in the bottle, affect the product quality and use effect, but also pose a potential threat to the user's health.

[0003] Moreover, the extruded structure exposed to the outside is also susceptible to damage during daily storage. During frequent use and placement, the extruded part may collide and rub against other objects, causing wear and tear, etc. This will not only shorten the service life of the dropper and increase the cost of use, but may also make the dropper unable to be squeezed normally or not sealed tightly during use, affecting the liquid absorption effect, resulting in the inability to accurately absorb and drip liquid, and reducing the convenience and reliability of use. In view of this situation, there is an automatic suction dropper, for example, a Chinese utility model patent with a publication number of CN220715908U discloses a bottle body and an outer cover, wherein the outer cover is arranged above the bottle body, and the top of the bottle body is connected to a bottle mouth for covering and mounting the outer cover, and a suction head extending upward from the outer cover is arranged inside the outer cover; the suction head comprises an upper cavity and a lower cavity which are vertically connected, the lower cavity extends into the interior of the outer cover, and the lower cavity and the upper cavity are both made of rubber material that can be squeezed and deformed, and the bottom of the suction head is connected to a suction pipe which vertically penetrates the bottle mouth and presses against the inner bottom of the bottle body to squeeze the lower cavity for compression and deformation. This type of dropper is provided with an extrudable and deformable suction head inside the outer cover. When the outer cover is unscrewed, the lower chamber is reset under the action of its own elasticity, so that the reagent can be automatically sucked into the suction head by means of the suction head during the process of separating the outer cover from the bottle mouth, thereby completing the automatic suction action. Its extrusion and suction structure is arranged inside the cover body, which can avoid the extrusion and suction structure being exposed to the air. However, this type of suction head dropper also has some shortcomings. During the process of screwing on and off the outer cover, the outer cover is gradually moved up or pressed down along the threads inside the cover body, so that the cover body squeezes the deformation chamber of the suction head while rotating, which makes the cover body generate greater resistance when tightening. At the same time, the extrusion and friction time of the deformation chamber of the suction head is longer. After a period of use, the elasticity of the deformation chamber of the suction head will decrease, thereby resulting in a decrease in the self-priming ability of the suction head and a shorter service life.

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0028] Embodiment: The offset extrusion type automatic material suction method is applied to liquid absorption, comprising a straw 3, on which is a connecting cover 1 connected to a bottle body containing liquid; the straw 3 is provided with a deformation cavity 4; a protective cover 6 is rotatably matched on the connecting cover 1, and an inner cover 16 sleeved on the deformation cavity 4 is provided on the inner side of the protective cover 6; when sucking materials, the rotating protective cover 6 drives the inner cover 16 to be dislocated with the deformation cavity 4, the deformation cavity 4 is elliptical, and the middle part of the inner cover 16 has an elliptical groove matched with the deformation cavity 4, the elliptical groove squeezes the deformation cavity 4 during the rotation process, the deformation cavity 4 is deformed by the offset extrusion, and because it is limited by the connecting cover 1, the protective cover 6 is continued to be rotated, and the protective cover 6 will drive the connecting cover 1 to rotate, the connecting cover 1 is screwed onto the bottle body, the protective cover 6 is loosened, and the protective cover 6 is reset, during which the deformation cavity 4 is restored and negative pressure is generated, and the liquid enters the deformation cavity 4 through the straw 3 to achieve material suction. The deformation chamber 4 is arranged in the middle of the straw 3, and the upper part of the straw 3 is a hard hollow structure, which is convenient for taking out the material after the straw 3 sucks.

[0029] The dropper for realizing the above-mentioned offset extrusion type automatic material suction method comprises a connecting cover 1 connected to the bottle body, the lower end of the connecting cover 1 is provided with a straw 3 extending into the bottle body; a deformation cavity 4 is provided on the straw 3, and the upper end of the deformation cavity 4 is connected to a picking head 2; a protective cover 6 is rotatably sleeved on the outer side of the connecting cover 1, and the outer side of the connecting cover 1 has a limiting structure for limiting the rotation stroke of the protective cover 6, and the limiting structure comprises a limiting block 20 symmetrically arranged on the outer side of the connecting cover 1 and a limiting strip 21 symmetrically arranged on the inner side of the protective cover 6, and the limiting strip 21 and the limiting block 20 are staggered at 90 degrees. When the protective cover is rotated, the limit bar rotates at the same time until one end of the limit bar conflicts with one end of the limit block, and the protective cover drives the connecting cover to rotate, and the connecting cover is tightened with the bottle body. The limit bar 21 and the limit block 20 are staggered at 90 degrees, so that the rotation stroke of the protective cover is a quarter of a circle, and the extrusion friction on the deformation cavity is also within the quarter of a circle. Compared with the full circle of extrusion friction in the prior art, it can improve the convenience of use. An inner cover 16 is arranged on the inner side of the protective cover 6; the inner cover 16 is sleeved on the deformation cavity 4; the picking head 2 is arranged through the upper end of the protective cover 6, as shown in the attached Figure 3 As shown; the deformation cavity 4 cooperates with the inner groove of the protective cover 6. The straw 3 includes a main body 11 inserted into the pick-up head 2, and a sleeve 12 is installed on the outer side of the main body 11.

The main body and the picking head can be stably connected through the connecting structure, and because the picking head is made of rubber, it is also more convenient to install the card.

[0030] The outer side of the lower end of the picking head 2 is provided with a first convex ring 7 and a second convex ring 8, and a fixing ring groove 9 is formed between the first convex ring 7 and the second convex ring 8.
