[0015] The technical scheme of the utility model will be introduced in detail below in combination with the drawings. The following implementation manners are all exemplary, and are intended to provide further description of the present application. Unless otherwise specified, all technical terms used have the same meaning as understood by the skilled person in the technical field to which the present application belongs. It should be noted that the terms used are only for describing the specific implementation manners, and are not intended to limit the exemplary implementation manners according to the present application.
[0016] The embodiment is a kind of liquid discharge device for centrifugal cup, in combination with Figs. 1 to 3 , including lifting driving part 1 and horizontal lifting plate 4, the lower end of the lifting driving part 1 is fixed, and the upper end is connected to the lifting plate 4, at least one long ejector rod 5 and at least one short ejector rod 6 are fixedly installed on the lifting plate 4, when the lifting driving part 1 drives the lifting plate 4 to move upwards, the long ejector rod 5 and the short ejector rod 6 can tilt the centrifugal cup 8 and lift it up, as shown in Fig. 3 When the lifting plate 4 moves upwards, the long ejector rod 5 first contacts the bottom of the centrifugal cup 8, so that the left side of the centrifugal cup 8 moves upwards, and then the right side contacts the short ejector rod 6, and after the lifting plate 4 stops moving, the long ejector rod 5 and the short ejector rod 6 jointly support the centrifugal cup 8 in an inclined state. In specific use, the experimenter needs to adjust the orientation of the centrifugal cup 8 when it is installed to the centrifugal module 7, so that the outlet at the bottom of the centrifugal cup 8 is at a low position when it is tilted, facilitating liquid discharge.

The fixed plate 2 is located above the lifting plate 4, and the long top rod 5 and the short top rod 6 are slidably arranged through the fixed plate 2. In this way, the support columns 3 can not only support the fixed plate 2, but also guide the lifting plate 4 to make it more stable when lifting.
[0019] The fixed plate 2 is fixed on the upper part of the centrifugal module 7, the lower end of the lifting driving element 1 is fixed on the lower part of the centrifugal module 7, and the upper end of the support column 3 is connected to the fixed plate 2 and the lower end is connected to the centrifugal module 7. This structure can make the liquid discharge device suitable for various types of centrifugal modules, facilitate the modification of the existing centrifugal modules in the laboratory, and reduce the modification cost.
[0020] The above is only the preferred embodiment of the present application. It should be pointed out that for ordinary skilled in the art, the liquid discharge device can not only be applied to the liquid discharge of the centrifugal cup, but also can be applied to the liquid discharge of other cell processing consumables. Without departing from the principle of the present application, those skilled in the art can make several changes or improvements, and these changes or improvements should also be regarded as the protection scope of the present application.
