Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] like Figures 1-4 ;

[0024] A dropper device for laboratory use includes a dropper body 1, and a dropper head mechanism 2 is provided on the top of the dropper body 1. The dropper head mechanism 2 can prevent the dropper from drawing liquid back into the rubber head.

[0025] The dropper head mechanism 2 includes a secondary tube 21, a support ring 22, and a tapered tube 23. The secondary tube 21 is fixedly connected to the top of the dropper body 1 and is used to support and install the rubber pusher head 26, preventing the rubber pusher head 26 from contacting the liquid. The support ring 22 is fixedly installed inside the dropper body 1 and is used to support and install the tapered tube 23. The tapered tube 23 is inserted into the support ring 22. The lower end of the tapered tube 23 is tapered, making it difficult for liquid drawn into the dropper body 1 to enter the tapered tube 23, and even if it does enter, it is very slow. The inside of the tapered tube 23 is filled with a sponge 231. When liquid enters the tapered tube 23, it is drawn in through the sponge 231. The outer wall of the conical tube 23 is respectively equipped with a first limiting plate 232 and a liquid outlet head 233. The first limiting plate 232 is used to support the conical tube 23 for limiting installation. When the liquid overflows from the sponge 231, it flows out slowly through the liquid outlet head 233. A rubber pad 234 is installed at the upper end of the conical tube 23. A rubber stopper 24 is inserted into the upper end of the dropper body 1. The rubber pad 234 increases the friction between the rubber stopper 24 and the rubber stopper 24. The lower end of the rubber stopper 24 is inserted into the upper end of the conical tube 23. The conical tube 23 can be pulled off the rubber stopper 24. When the rubber stopper 24 is pulled out upwards, the rubber stopper 24 will pull out the conical tube 23 together, which makes it easy to replace the conical tube 23.

[0026] A second limiting piece 25 is installed inside the secondary tube 21. The second limiting piece 25 has a through hole 251 in the middle. The second limiting piece 25 limits the insertion position of the rubber pusher head 26. By providing the through hole 251, the gas flow within the secondary tube 21 and the dropper body 1 is not affected. The end of the secondary tube 21 furthest from the dropper body 1 is slidably inserted into the rubber pusher head 26. A push rod 261 is installed on the rubber pusher head 26. Pushing the push rod 261 causes the rubber pusher head 26 to slide within the secondary tube 21, thus connecting the secondary tube 21 and the dropper body. Air is expelled from the main body 1. A side lug 262 is fixedly installed on the outer wall of the secondary tube 21. The side lug 262 facilitates the use of the hand to push or pull the push rod 261. A connector 28 is fixedly installed at the bottom of the secondary tube 21. The liquid flowing out of the liquid outlet 233 can flow into the glass bottle 29 through the connector 28. The glass bottle 29 is threaded onto the connector 28. A screw plate 291 is fixedly installed at the bottom of the glass bottle 29. Rotating the screw plate 291 at the bottom of the glass bottle 29 will rotate the glass bottle 29, making it easy to disassemble and install the glass bottle 29.

[0027] The dropper body 1 has a scale 27 on its side wall. By observing the scale, it is easy to observe the height of the liquid slowly entering the dropper body 1, thus improving the accuracy of the liquid.

[0028] The working principle of this utility model is as follows: The side wall of the dropper body 1 is provided with a scale 27, the secondary tube 21 is fixedly connected to the top of the dropper body 1, the support ring 22 is fixedly set inside the dropper body 1, the conical tube 23 is inserted into the support ring 22, the inside of the conical tube 23 is filled with a sponge 231, the outer wall of the conical tube 23 is respectively installed with a first limiting piece 232 and a liquid outlet head 233, the upper end of the conical tube 23 is installed with a rubber pad 234, the inside of the secondary tube 21 is installed with a second limiting piece 25, and the second limiting piece 25 has a through hole 251 in the middle. The end of the secondary tube 21 furthest from the dropper body 1 is slidably inserted into the rubber pusher 26. A push rod 261 is mounted on the rubber pusher 26. A connector 28 is fixedly installed at the bottom of the secondary tube 21, with a glass bottle 29 threaded onto the connector 28. Pushing the push rod 261 causes the rubber pusher 26 to slide within the secondary tube 21, expelling air from both the secondary tube 21 and the dropper body 1. The second limiting piece 25 limits the position of the rubber pusher 26. The lower end of the dropper body 1 is inserted into the reagent. Pulling the push rod 261 causes it to slide within the secondary tube 21, allowing the dropper body 1 to begin drawing reagent. Because the lower end of the conical tube 23 is conical, the reagent is slowly drawn into the dropper body 1. Observing the scale allows for easy monitoring of the liquid level slowly entering the dropper body 1, improving accuracy. If too much reagent is drawn in... The lower end of the conical tube 23 is conical, making it difficult for reagents to enter. Even if reagents do enter the conical tube 23, the entry is very slow. When liquid enters the conical tube 23, it is drawn in by the sponge 231. After the liquid overflows from the sponge 231, it flows out slowly through the outlet head 233. The liquid flowing out of the outlet head 233 can flow into the glass bottle 29 through the connector 28 for collection. This not only allows the reagent to be slowly drawn out by the rubber pusher head 26, but also prevents the reagent from contacting the rubber pusher head 26. The upper end of the dropper body 1 is inserted with a rubber stopper 24. The lower end of the rubber stopper 24 is inserted into the upper end of the conical tube 23. When the rubber stopper 24 is pulled out upwards, the rubber stopper 24 will pull out the conical tube 23 along with it, making it easy to remove and replace the conical tube 23. When the conical tube 23 is inserted into the dropper body 1, it is limited by the first limiting piece 232, which is exactly inserted into the upper end of the dropper body 1.
