Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-8 , a technical solution provided by the present utility model:

[0030] A reagent kit capable of quickly preparing gel includes a box body 1. A placement table 5 is fixedly connected inside the box body 1. A plurality of slots (not shown in the figure) are opened at the top of the placement table 5. A plurality of reagent bottles 2 are movably inserted into the slots. The placement table 5 is in a stepped shape to adapt to reagent bottles 2 of different heights. A sampling mechanism 3 is arranged inside the reagent bottle 2 for extracting the reagent inside the reagent bottle 2. A placement cavity is arranged on the box body 1, and a drain pipe 4 is placed in the placement cavity. The drain pipe 4 is used to cooperate with the sampling mechanism 3 to export the reagent inside the reagent bottle 2 out of the bottle body.

[0031] Please refer to Figure 2, a docking hole 201 is provided on the peripheral wall of the reagent bottle 2 for connecting the drain pipe 4, so that the purpose of sampling can be achieved without taking the sampling mechanism 3 out of the reagent bottle 2. A sealing ring 6 is threadedly connected to the peripheral wall of the reagent bottle 2 for controlling the opening and closing of the docking hole 201. When sampling is required, the sealing ring 6 can be rotated downward to open the docking hole 201. After sampling is completed, the sealing ring 6 can be rotated upward to close the docking hole 201 by the sealing ring 6 to prevent the inside of the reagent bottle 2 from being contaminated. A plurality of protrusions 7 are fixedly connected to the peripheral wall of the sealing ring 6 to facilitate the rotation of the sealing ring 6.

[0032] Specifically, the sampling mechanism 3 in the present embodiment includes a liquid extraction tube 301 fixedly connected to the inner wall of the reagent bottle 2, the top of the liquid extraction tube 301 penetrates the reagent bottle 2 and is fixedly connected with a rubber cap 302, and by controlling the deformation degree of the rubber cap 302, the air pressure in the liquid extraction tube 301 can be controlled, thereby controlling the extraction and discharge of liquid. The liquid extraction tube 301 is a glass tube, and a scale line (not shown in the figure) is provided on its surface to facilitate the control of the amount of liquid extraction. The bottom end of the liquid extraction tube 301 is connected with a liquid extraction tube 304 and a liquid outlet tube 305 through a flow guide device, and one end of the liquid outlet tube 305 away from the flow guide device is fixedly connected to the inner wall of the docking hole 201, and can be threadedly connected with one end of the liquid discharge tube 4, thereby facilitating the connection and disassembly of the liquid discharge tube 4 and the liquid outlet tube 305.

[0033] See also Figure 5 The flow guiding device includes a shell 303 fixedly connected to the inner wall of the reagent bottle 2, and the liquid extraction tube 301, the liquid collection tube 304, and the liquid outlet tube 305 are all fixedly plugged into the inner wall of the shell 303, wherein the liquid extraction tube 301 and the liquid collection tube 304 are respectively plugged into the inner walls of the two opposite ends of the shell 303, and the liquid outlet tube 305 is plugged into the inner wall of the shell 303 along the radial direction. A cavity is opened inside the shell 303, and the liquid extraction tube 301, the liquid collection tube 304, and the liquid outlet tube 305 are all connected to the inside of the cavity. The piston in the cavity is connected to a sealing block 306, which can seal one end of the liquid outlet pipe 305, and the bottom end of the sealing block 306 is connected to the inner wall of the shell 303 through a spring 307. When the air pressure above the sealing block 306 increases to a certain value, the sealing block 306 can be pushed to move downward to release its sealing effect on one end of the liquid outlet pipe 305, so that the fluid in the liquid extraction tube 301 can be discharged through the liquid outlet pipe 305.

[0034] Combination Figure 5 and Figure 7As shown, a first stop portion 3032 is provided on the inner top wall of the cavity, and a second stop portion 3033 is provided on the inner bottom wall of the cavity. The first stop portion 3032 and the second stop portion 3033 are respectively used to contact the two ends of the sealing block 306 to limit the upward and downward movement strokes of the sealing block 306 and ensure the sealing and unsealing effects. A concave-shaped diversion channel 3031 is formed inside the housing 303. Both ends of the diversion channel 3031 communicate with the inside of the cavity, and the top end of the diversion channel 3031 is located above the first stop portion 3032. When the top end of the sealing block 306 contacts the first stop portion 3032, the bottom end of the diversion channel 3031 is in communication with the inner cavity of the reagent bottle 2, so that the liquid in the liquid extraction tube 304 can be drawn into the liquid suction tube 301.

[0035] Please refer to Figure 8 , the inner bottom wall of the reagent bottle 2 is a conical surface 202. A groove 203 is formed downward at the center position of the conical surface 202. The bottom end of the liquid extraction tube 304 is located in the groove 203. Through the conical surface 202, the reagent in the reagent bottle 2 can be introduced into the groove 203, which is convenient for the liquid extraction tube 304 to extract, thus avoiding the waste of remaining liquid.

[0036] When the gel-rapidly configurable kit of the present invention is in use, first, the sealing ring 6 is rotated by the convex block 7. During the rotation of the sealing ring 6, it moves downward, so that the docking hole 201 is exposed. Subsequently, the drain pipe 4 is threadedly connected to the liquid outlet pipe 305 in the docking hole 201, and the bottom end of the drain pipe 4 is extended into the container. Subsequently, the rubber cap 302 is quickly squeezed, so that the gas in the rubber cap 302 quickly enters the housing 303 through the liquid suction tube 301, pushing the sealing block 306 downward, blocking the opening at the bottom end of the diversion channel 3031, and opening one end of the liquid outlet pipe 305. The gas is discharged out of the device through the liquid outlet pipe 305. After the air pressure decreases, the sealing block 306 moves upward under the elastic force of the spring 307 to block one end of the liquid outlet pipe 305 again. Subsequently, the rubber cap 302 is slowly released to make the inside of the liquid suction tube 301 in a negative pressure state. The liquid in the reagent bottle 2 enters the liquid suction tube 301 through the liquid extraction tube 304, the cavity and the diversion channel 3031. After a certain amount of liquid is taken, the rubber cap 302 is quickly squeezed again, so that the reagent enters the container through the liquid outlet pipe 305 and the drain pipe 4.

[0037] After the liquid extraction is completed, the drain pipe 4 is threadedly separated from the liquid outlet pipe 305, and then the sealing ring 6 is rotated in the reverse direction to re-seal the docking hole 201 to prevent the inside of the reagent bottle 2 from being contaminated.
