[0033] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] As Figures 1 - 7 shown, a splash-proof beaker lid in an embodiment of the present utility model includes a beaker lid body 1. A spiral flow channel 7 is arranged inside the beaker lid body 1. An outlet 3 and an inlet 4 are respectively arranged at both ends of the flow channel 7. The inlet 4 is located on the upper end face of the beaker lid body 1, facilitating the dropping of reagents or solutions from above the beaker lid body 1. The outlet 3 is located on the side wall of the beaker lid body 1. The dropped reagents or solutions can flow out from the side wall of the beaker lid body 1 through the outlet 3, so that they can flow down along the beaker wall.

[0035] Specifically, through the diversion structure formed by the outlet 3, the inlet 4 and the flow channel 7, the dropped reagents or liquids can be guided and buffered, so that the reagents or liquids can slowly flow down along the inner wall of the beaker, effectively avoiding the splashing of solutions such as concentrated sulfuric acid in the beaker outward, so as to safely add reagents or solutions such as hydrogen peroxide.

[0036] The longitudinal section of the beaker lid body 1 is trapezoidal in an inverted shape, facilitating the fitting of the beaker lid body 1 with the beaker and facilitating the installation and use of the beaker lid body 1.

[0037] As Figure 7 shown, a diversion port 401 is arranged at the edge position of the top end of the inlet 4, facilitating the dropped reagents or solutions to enter the inside of the flow channel 7 and avoiding the residues of the reagents or solutions on the inlet 4.

[0038] As Figure 1 and Figure 7 shown, an adjustment control structure is arranged above the inlet 4. The adjustment control structure includes a rotating rod 2. The rotating rod 2 is rotatably connected to the center position of the top end of the beaker lid body 1. A connecting bridge 201 is fixedly connected to the outside of the rotating rod 2 through a bolt. One end of the connecting bridge 201 away from the rotating rod 2 is fixedly connected to an adjustment disk 6.

[0039] A slideway groove 5 is arranged on the beaker lid body 1. The slideway groove 5 is located above the inlet 4. The adjustment disk 6 is slidably connected to the inside of the slideway groove 5. The slideway groove 5 is arc-shaped. The rotating rod 2 is located at the center of the circle where the slideway groove 5 is located. That is to say, by rotating the rotating rod 2, the rotating rod 2 can drive the adjustment disk 6 to make a circular slide inside the slideway groove 5 through the connecting bridge 201.

[0040] Among them, the width of the slideway groove 5 is greater than the diameter of the inlet 4. The outer wall of the adjustment disk 6 fits with the inner wall of the slideway groove 5. That is, the diameter of the adjustment disk 6 is greater than the diameter of the inlet 4, and the adjustment disk 6 can completely block the inlet 4 to realize the blocking and sealing of the inlet 4.

[0041] The bottom end of the adjustment disk 6 fits with the bottom end inside the slideway groove 5, and a rubber pad is fixedly connected to the bottom end of the adjustment disk 6. This can effectively ensure the sealing performance when the adjustment disk 6 seals the inlet 4.

[0042] Specifically, as Figure 3 and Figure 4 shown, by rotating the rotating rod 2, the adjusting disc 6 is driven to slide inside the slideway groove 5. When the adjusting disc 6 partially blocks the liquid inlet 4, the size of the liquid inlet 4 can be adjusted by adjusting the blocking area, thereby adjusting the dropping speed of the reagent or solution. When the adjusting disc 6 completely blocks the liquid inlet 4, the liquid inlet 4 is completely sealed to prevent the gas or solution inside the beaker cover body 1 from leaking out, so as to ensure the safe use of the beaker cover body 1.

[0043] As Figures 5 - 7 shown, a plurality of groups of positioning notches 501 are formed on the side wall of the slideway groove 5. An expansion slot 602 is formed on the side wall of the adjusting disc 6. A spring 603 is fixedly connected inside the expansion slot 602. One end of the positioning block 601 extends into the expansion slot 602 and is fixedly connected to one end of the spring 603. The positioning block 601 can elastically expand and contract inside the expansion slot 602.

[0044] Among them, one end of the positioning block 601 away from the adjusting disc 6 is arc-shaped, which is convenient for the positioning block 601 to slide into the plurality of groups of positioning notches 501. That is to say, the positioning block 601 can slide into the plurality of groups of positioning notches 501 in sequence to realize the positioning of the adjusting disc 6 at different positions inside the slideway groove 5, prevent the adjusting disc 6 from accidentally sliding during use, and ensure the stability of the adjusting disc 6 during use.

[0045] A lifting ball 202 is fixedly connected to the top end of the rotating rod 2. By means of the lifting ball 202, it is convenient to manually rotate the rotating rod 2 and also convenient to pull the beaker cover body 1 to remove it from the beaker, which brings convenience to the installation and use of the beaker cover body 1.

[0046] During use, weigh a certain amount of carbon fiber reinforced plastic and place it in a beaker, pour a certain amount of concentrated sulfuric acid into it, then fix the beaker cover body 1 on the beaker, and finally transfer them together to a heating plate for heating. After the resin is basically digested, suck a certain amount of hydrogen peroxide reagent and drop it into the liquid inlet 4, so that the hydrogen peroxide flows along the flow channel 7 and finally flows out along the beaker wall at the liquid outlet 3 until the solution is clear. After the solution cools down, remove the beaker cover body 1.

[0047] A splash-proof beaker cover of the present utility model can slowly drop the reagent or solution under the condition of heating the solution by arranging the liquid outlet 3, the liquid inlet 4 and the flow channel 7, effectively preventing the solution from splashing out of the beaker, greatly improving the safety, and having the advantages of simple structure and convenient operation;

[0048] By controlling the sliding of the adjusting disc 6 inside the slideway groove 5, it is convenient to adjust the size of the liquid outlet 3, thereby controlling the liquid adding speed, and can also control the closing of the liquid outlet 3, which is convenient for the safe use of the beaker cover body 1.

[0049] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
