Background
The kit is a laboratory-used test device for storing a wide variety of liquid reagents used in some tests. When a test person needs to remove a reagent from a reagent kit, it is a common practice to have the test person open the lid of the reagent kit, then aspirate a certain amount of the reagent using a syringe or a dropper, and then re-use the reagent for the test operation. Because this process requires manual operation, the test personnel can also easily get contaminated on the hands, on the body or on the test equipment if the operation is unskilled or unnoticed. The consequences may be severe if the reagents used are corrosive or toxic to some extent. Although some reagent kits for adding reagents are available in the market, the reagent kits simply use air pressure to press out the reagents, and the air inlet and the liquid storage tank of the reagents are basically in a direct blowing mode, so that the adding amount of the reagents is unstable due to uneven air inlet, and meanwhile, the reagents are caused to flow back from the air inlet due to improper operation.

Further, a second gas storage compartment is arranged at the other end of the first flow channel, and the second gas storage compartment is communicated with the second flow channel through a first air hole.
Further, an overflow groove is formed in one end, close to the liquid storage groove, of the second flow channel, and the overflow groove is communicated with the liquid storage groove through a third flow channel.
Further, a water absorbing sponge is arranged in the overflow groove.
Further, a third gas storage compartment is arranged at the other end of the second flow channel, the first gas hole is arranged in the third gas storage compartment, and the end part of the first gas hole extends into the third gas storage compartment.
Further, an air inlet bin communicated with the air inlet is arranged in the box body, an air storage bin communicated with the air inlet bin is arranged below the air inlet bin, the air storage bin is communicated with the slender runner, the air inlet bin is communicated with the air storage bin through a second air hole, and two ends of the second air hole extend into the air inlet bin and the air storage bin respectively.
Further, the gas storage bin is communicated with a fourth gas storage compartment, and the fourth gas storage compartment is communicated with the slender runner.
The invention has the positive effects that: the air inlet is communicated with the liquid storage tank through the slender flow channel, the air can be fully and uniformly mixed in the flowing process of the slender flow channel, the influence of uniformity of the air at the air inlet is avoided, the uniformity of the liquid entering the liquid storage tank is ensured, the uniformity of the discharge of the reagent from the liquid storage tank is ensured, and the metering of the quantity of the discharged reagent is facilitated. Meanwhile, a plurality of gas storage compartments are arranged in the flow channel, so that the uniform effect of the entering gas can be realized, meanwhile, the gas storage compartments can store liquid, when the reagent in the liquid storage tank flows back, the gas storage compartments can be filled at first, and finally, the reagent can flow into the air inlet, and the liquid can be effectively prevented from flowing back into the air inlet. And the ends of the first air hole and the second air hole extend into the corresponding bin, and only when the liquid level in the bin is higher than the end, the liquid level in the bin can enter the next bin through the air holes, so that backflow can be further prevented.

Detailed Description
As shown in fig. 1 and 2, the invention comprises a box body 15, an air inlet 1 arranged on the side surface of the box body 15, a liquid storage tank 8 communicated with the air inlet 1 through an elongated runner and a liquid outlet 14 communicated with the liquid storage tank 8. The reservoir 8 is located inside the box 15, and the liquid outlet 14 is mounted on the side of the box 15 and at the bottom of the reservoir 8.
The slender flow channel comprises a first flow channel 11 positioned at the lower part of the box body 15 and a second flow channel 5 arranged at the upper part of the box body 15 and communicated with the first flow channel 11, one end of the first flow channel 11 is communicated with the air inlet 1, and one end of the second flow channel 5 is communicated with the liquid storage groove 8. The first flow channel 11 and the second flow channel 5 are both in continuous S-shaped design, so that the conveying time of the gas in the flow channels can be further prolonged, and sufficient time is provided for uniformly mixing the gas and conveying the gas into the liquid storage tank 8.
The gas inlet bin 2 communicated with the gas inlet 1 is arranged in the box body 15 as seen in the flowing direction of the gas in the box, the gas storage bin 16 communicated with the gas inlet bin 2 is arranged below the gas inlet bin 2, the fourth gas storage bin 10 communicated with the gas storage bin 16 is arranged on one side of the gas storage bin 16, the fourth gas storage bin 10 is communicated with one end of the first flow channel 11, the first gas storage bin 12 and the second gas storage bin 13 are sequentially communicated with the other end of the first flow channel 11, one side, far away from the first gas storage bin 12, of the second gas storage bin 13 is communicated with the third gas storage bin 17 through the first gas holes 4, one end of the second flow channel 5 is communicated with the third gas storage bin 17, the other end of the second flow channel 5 is communicated with the overflow groove 6, and the overflow groove 6 is communicated with the liquid storage groove 8 through the third flow channel 7. The first flow channel 11, the second flow channel 5 and the third flow channel 7 are all of a continuous S-shaped design. Through the design of a series of S-shaped flow channels, a plurality of gas storage compartments and an overflow groove 6, the time for gas to enter the liquid storage groove 8 from the gas inlet 1 can be greatly prolonged, the entering gas can be fully mixed in the structures, and even if the gas entering from the gas inlet 1 is uneven, the gas can be fully and uniformly mixed when entering the liquid storage groove 8 after being transported for a long time.
The second flow channel 5 and the communication part between the third flow channel 7 and the overflow groove 6 are all positioned at the top of the overflow groove 6, when the reagent in the liquid storage groove 8 flows back, the reagent can flow into the overflow groove 6 first, and the reagent can continuously enter the second flow channel 5 only after the overflow groove 6 is filled.
Meanwhile, the part of the first air hole 4 positioned in the third air storage compartment 17 stretches into the third air storage compartment 17, the fixed top of the part is higher than the bottom plate of the third air storage compartment 17, when the overflow groove 6 is filled with reagents and continuously flows back from the second flow channel 5, the reagents need to enter the third air storage compartment 17, and when the liquid level is higher than the end part of the first air hole 4, the reagents can continuously flow into the second air storage compartment 13 from the first air hole 4.
These structures can store the reagent that flows back when the reagent flows back, effectively preventing the reagent from flowing back into the air inlet 1.
Furthermore, a water-absorbing sponge can be placed in the overflow groove 6 to absorb the reflowing reagent, and the backflow prevention effect can be further improved.
The air inlet bin 2 is communicated with the air storage bin 16 through the second air holes 3, and two ends of the second air holes 3 extend into the air inlet bin 2 and the air storage bin 16 respectively.
