[0001] The utility model relates to the technical field of dropper bottle devices, in particular to a rubber-tipped dropper with automatic material suction. Background Art

[0002] A dropper bottle is a common laboratory item, and its main function is to store and dispense chemical reagents. It usually includes a long and thin pipette and a container with a scale. When using the current dropper bottle, the tip of the rubber-tipped dropper structure and the pipette need to be removed from the bottle body, and then the tip is manually squeezed to suck the reagent from the bottle body into the tip, which requires manual aspiration and is cumbersome to use.

[0003] Utility Model Content

[0004] The purpose of the utility model is to provide a rubber-tipped dropper with automatic material suction in order to solve the above-mentioned problems. By arranging an extrudable and deformable suction head inside the outer cover, the lower cavity is reset under the action of its own elasticity when the outer cover is unscrewed, so that the reagent can be automatically sucked into the suction head by using the straw during the process of separating the outer cover from the bottle mouth, thereby completing the automatic material suction action. The utility model is convenient to use, simple in structure, low in cost, and has a better promotion prospect. Details are explained below.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The utility model provides an automatic material suction rubber dropper, comprising 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 is arranged inside the outer cover and extends upward from the outer cover;

[0007] The suction head includes an upper cavity and a lower cavity that are vertically connected. The lower cavity extends into the interior of the outer cover. Both the lower cavity and the upper cavity are made of extrudable and deformable rubber material. The bottom of the suction head is connected to a straw that vertically penetrates the bottle mouth and presses against the bottom of the bottle body to squeeze the lower cavity for compression and deformation.

[0008] The above-mentioned automatic material-suctioning rubber-tipped dropper is used. When in use, the outer cover supports the suction head and the straw cover is closed to the bottle mouth on the upper side of the bottle body, the suction head supports the straw and extends into the bottle body. The bottom end of the straw gradually presses against the bottom of the bottle body as the suction head and the outer cover move downward. The straw cooperates with the outer cover to support the lower cavity to produce compression deformation, so as to discharge the air inside the lower cavity from the bottom end of the straw, and at the same time, the outer wall of the bottom end of the lower cavity presses against the inner wall of the pressing sleeve to seal the bottle mouth. When it is necessary to take the reagent in the bottle body, the outer cover is screwed upward, and the suction head and straw are driven upward by the outer cover, the pressing state of the straw is gradually released, and the lower cavity is reset and supported under its own elastic force, so that the reagent inside the bottle body is sucked into the lower cavity by the lower cavity, completing the automatic material suction action.

[0009] Preferably, the outer side of the bottle mouth is provided with an external thread, and the inner wall of the outer cover is provided with an internal thread that matches the external thread.

[0010] Preferably, a snap ring is provided on the inner side of the top of the outer cover, and a clamping groove which is clamped to the inner side of the snap ring is provided on the outer side of the junction between the upper cavity and the lower cavity.

[0011] Preferably, a circular constraint groove is provided on the inner side of the bottom opening of the lower cavity, and the top opening of the straw extends outward to form a constraint ring which is clamped tightly against the constraint groove.

[0012] Preferably, the bottom end of the straw is gathered inwardly to form a concave annular suction nozzle.

[0013] Preferably, a pressing sleeve is provided on the inner side of the bottle mouth to accommodate a straw passing vertically therethrough. The interior of the pressing sleeve is in the shape of a cone with a larger top and a smaller bottom, and the top end of the pressing sleeve extends outward to form a convex edge that presses against the top end of the bottle mouth.

[0014] Preferably, the top side of the convex edge is tightly pressed against the outer side of the bottom end of the lower cavity, and the bottom end of the lower cavity extends downward to form a cone sleeve adapted to the inner wall of the pressing sleeve.

[0015] Preferably, the outer wall of the lower cavity is in any one of a wavy, oblique stripe or tower shape.

[0016] The beneficial effect is that: the utility model provides an extrudable and deformable suction head inside the outer cover. When the outer cover and the suction head cover are closed on the bottle mouth, the suction pipe is used to press against the bottom wall of the bottle body, thereby squeezing the lower cavity inside the outer cover to cause deformation to discharge the air in the lower cavity. Thereafter, when the outer cover is unscrewed, the lower cavity is reset under the action of its own elasticity, so that the reagent is automatically sucked into the suction head by the suction pipe during the process of separating the outer cover from the bottle mouth, thereby completing the automatic material suction action. The utility model is convenient to use, simple in structure, low in cost, and has better promotion prospects. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0027] 1 to 6 , the present invention provides a plastic dropper for automatic material suction, comprising a bottle body 1 and an outer cover 3. The outer cover 3 is disposed above the bottle body 1, and the top of the bottle body 1 is connected to a bottle mouth 2 for covering and mounting the outer cover 3. A suction head 4 is disposed inside the outer cover 3 and extends upward from the outer cover 3.

[0028] The suction head 4 includes an upper cavity 401 and a lower cavity 402 that are vertically connected. The lower cavity 402 extends into the interior of the outer cover 3. Both the lower cavity 402 and the upper cavity 401 are made of extrudable and deformable rubber material. The bottom of the suction head 4 is connected to a straw 5 that vertically penetrates the bottle mouth 2 and presses against the bottom of the bottle body 1 to squeeze the lower cavity 402 for compression and deformation. The suction head 4 and the straw 5 are connected to form a rubber-tipped dropper structure.

[0029] As an optional embodiment, the outer side of the bottle mouth 2 is provided with an external thread 201, and the inner wall of the outer cover 3 is provided with an internal thread 302 that is threadedly matched with the external thread 201, ensuring that the outer cover 3 can be screwed and disassembled outside the bottle mouth 2. A snap ring 301 is provided on the inner side of the top of the outer cover 3, and a groove 403 that is clamped to the inner side of the snap ring 301 is provided on the outer side of the junction between the upper cavity 401 and the lower cavity 402, ensuring that the pipette tip 4 can be stably installed inside the outer cover 3;

[0030] A circular restraining groove 404 is provided on the inner side of the bottom opening of the lower chamber 402. The top opening of the straw 5 extends outward to form a restraining ring 501 that is clamped and tightly abutted in the restraining groove 404, ensuring that the lower chamber 402 and the lower side straw 5 can be stably connected. The bottom end of the straw 5 gathers inward to form a concave annular suction nozzle 502. A pressing sleeve 6 is provided on the inner side of the bottle mouth 2 to accommodate the straw 5 vertically passing through. The interior of the pressing sleeve 6 is a conical cylinder with a larger upper part and a smaller lower part. The top end of the pressing sleeve 6 extends outward to form a convex edge that abuts against the top of the bottle mouth 2, ensuring that when the suction head 4 is pressed against the inner side of the bottle mouth 2, it can be pressed against the lower chamber 402 through the pressing sleeve 6, thereby achieving a seal on the bottle mouth 2.

[0031] The top side of the convex edge is tightly pressed against the outer side of the bottom end of the lower cavity 402, and the bottom end of the lower cavity 402 extends downward to form a tapered sleeve adapted to the inner wall of the pressing sleeve 6. The outer wall of the lower cavity 402 is any one of wavy, oblique striped or tower-shaped, preferably wavy, so as to facilitate the compression and deformation of the lower cavity 402. When the straw 5 is pressed against the inner bottom wall of the bottle body 1, the lower cavity 402 is squeezed and deformed to expel the air therein.

[0032] After the bottle mouth 2 is closed, the outer cover 3 is screwed up, and the outer cover 3 is used to support the suction head 4 and the suction pipe 5 to cover the bottle mouth 2 on the upper side of the bottle body 1. The suction head 4 supports the suction pipe 5 to extend into the bottle body 1, and the bottom end of the suction pipe 5 gradually presses against the bottom of the bottle body 1 as the suction head 4 and the outer cover 3 move downward. The suction pipe 5 cooperates with the outer cover 3 to support the lower chamber 402 to produce compression deformation, so that the air in the lower chamber 402 is discharged from the bottom end of the suction pipe 5, and at the same time, the outer wall of the bottom end of the lower chamber 402 presses against the inner wall of the pressing sleeve 6 to seal the bottle mouth 2; when it is necessary to take the reagent in the bottle body 1, the outer cover 3 is screwed up, and the suction head 4 and the suction pipe 5 are moved up by the outer cover 3, and the pressing state of the suction pipe 5 is gradually released, and the lower chamber 402 is reset and supported under its own elastic force, so that the reagent in the bottle body 1 is sucked into the lower chamber 402 by the lower chamber 402, completing the automatic suction action;

[0033] By arranging an extrudable and deformable suction head 4 inside the outer cover 3, when the outer cover 3 and the suction head 4 are covered on the bottle mouth 2, the suction pipe 5 is used to press against the inner bottom wall of the bottle body 1, thereby squeezing the lower cavity 402 inside the outer cover 3 to cause deformation and discharge the air in the lower cavity 402, and then when the outer cover 3 is screwed off, the lower cavity 402 is reset under the action of its own elasticity, so that the reagent is automatically sucked into the suction head 4 by the suction pipe 5 during the process of separating the outer cover 3 from the bottle mouth 2, completing the automatic material suction action. It is convenient to use, simple in structure, low in cost, and has a better promotion prospect.
