DETAILED DESCRIPTION

[0018] like Figure 1-3 As shown, a new type of staining cup comprises a main body 1, the top surface of the main body 1 is provided with a liquid inlet Ⅰ2, the middle side wall of the main body 1 is connected with a liquid inlet Ⅱ3, the bottom side wall of the main body 1 is connected with a liquid inlet Ⅲ4, and the bottom surface of the main body 1 is connected with a liquid discharge port 5; specifically, in actual use, the liquid inlet Ⅰ2, the liquid inlet Ⅱ3, and the liquid inlet Ⅲ4 are all connected to a liquid inlet pipe, a liquid inlet valve is installed on the liquid inlet pipe, and whether liquid is fed into the main body 1 is controlled by the valve, the liquid discharge port 5 is connected with a liquid discharge pipe, a liquid discharge valve is installed on the liquid discharge pipe, and the stained sample in the main body 1 can be discharged by opening the liquid discharge valve.

[0019] like Figure 3 As shown, the main body 1 includes a first cylindrical section 101, a first conical section 102, a second cylindrical section 103, and a second conical section 104 which are connected in sequence from top to bottom, the liquid inlet I2 is opened on the top surface of the first cylindrical section 101, the liquid inlet II3 is connected to the side wall of the first cylindrical section 101 near the bottom, the liquid inlet III4 is connected to the side wall of the second conical section 104 near the bottom, and the liquid discharge port 5 is connected to the bottom surface of the second conical section 104.

[0020] Specifically, the inner diameter of the first cylindrical section 101 is equal to the inner diameter of the top surface of the first conical section 102, the inner diameter of the second cylindrical section 103 is equal to the inner diameter of the bottom surface of the first conical section 102, and the inner diameter of the top surface of the second conical section 104 is equal to the inner diameter of the second cylindrical section 103. The size of the liquid inlet I2 is the same as the inner diameter of the first cylindrical section 101; the body 1 is designed in such a shape with a constantly changing inner diameter, the first cylindrical section 101 has the largest opening on the top, which is convenient for adding dye, and the inner diameter is getting smaller and smaller, so that the sample accumulates at the bottom with a small contact area, which is easy to mix and also convenient for cleaning the inner wall of the dye cup.

[0021] A lifting ear 6 is connected to the edge of the top surface of the first cylindrical section 101 , and a through hole 601 is opened on the lifting ear 6 ; the number of the lifting ears 6 is set to two, and the two lifting ears 6 are arranged symmetrically on the left and right.

[0022] The use process of the utility model is as follows:
