[0002] Gene transfer instrument is a device used to transfer exogenous DNA molecules into certain biological cells, and the electroporation cup is an important component of the device. In short, the electroporation cup is a very important component of the gene transfer instrument. The correct use of the electroporation cup can improve the transfection efficiency and cell survival rate.
[0003] In the related art, the electric rotating cup is usually composed of four parts: the electric rotating cup body, the electric rotating cup cover, the lower electrode and the upper electrode. The electric rotating cup cover is usually installed on the electric rotating cup body in a flip-opening and closing manner. With the flip-opening method, the electric rotating cup body must be filled with liquid before it can touch the liquid surface. Once it is filled too much, it is easy to overflow when the cover is closed; and most of the electric rotating cup covers do not have pressure relief holes. When the liquid in the electric rotating cup body expands due to heat, the gas cannot be discharged, and then the electric rotating cup cover can be easily pushed open by the air pressure. Therefore, we propose a screw-cover electric rotating cup to solve the above problems. Utility Model Content

The liquid in the cup is not easy to overflow, and when the liquid in the electric rotating cup body expands due to heat, it can be exhausted from the pressure reducing hole, and the electric rotating cup cover will not be pushed open.

DETAILED DESCRIPTION
[0025] The technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
[0026] See also Figure 1-7 The present application provides a screw-cover electric rotating cup, comprising an electric rotating cup body 1, an electric rotating cup cover 2, a lower electrode 3 and an upper electrode 4, wherein the electric rotating cup cover 2 is threadedly mounted on the top of the electric rotating cup body 1, the upper electrode 4 is arranged on the electric rotating cup cover 2, and the lower electrode 3 is arranged inside the bottom end of the electric rotating cup body 1, wherein:
[0027] The electric rotating cup body 1 includes an outer cup shell 11 and an inner cup shell 12. The top and bottom ends of the outer cup shell 11 are both open structures, and the top and bottom ends of the inner cup shell 12 are both open structures. The outer cup shell 11 is fixedly sleeved on the outer wall of the inner cup shell 12. An external thread 6 is provided on the top outer wall of the outer cup shell 11, and an internal thread 7 is provided on the inner wall of the electric rotating cup cover 2. The electric rotating cup cover 2 is threadedly connected with the external thread 6 on the outer cup shell 11 through the internal thread 7. By utilizing the connection and cooperation between the external thread 6 and the internal thread, it is convenient to use a rotating method to screw and remove the electric rotating cup cover 2 from the electric rotating cup body 1, and it is also convenient to screw the electric rotating cup cover 2 back onto the electric rotating cup body 1.
[0028] In this embodiment, in order to prevent the top and bottom of the inner cup shell 12 from extending out of the outer cup shell 11 , the length of the outer cup shell 11 is set to be greater than the length of the inner cup shell 12 .
[0029] In this embodiment, a through hole 5 is opened on the top of the electric rotating cup cover 2, and the top of the upper electrode 4 passes through the through hole 5. A connecting plate 41 is fixedly installed on the bottom of the upper electrode 4. The connecting plate 41 is fixedly connected to the top inner wall of the electric rotating cup cover 2. The through hole 5 is set to facilitate the assembly of the upper electrode 4 on the electric rotating cup cover 2. The diameter of the connecting plate 41 is larger than the diameter of the through hole 5. The connecting plate 41 is used to block the bottom opening of the through hole 5 to prevent the liquid in the cup from entering the through hole 5. The lower electrode 3 is located in the inner cup shell 12. A connecting plate 31 is fixedly installed on the bottom of the lower electrode 3. The connecting plate 31 is fixedly installed on the bottom end of the inner cup shell 12 and is located in the outer cup shell 11. The diameter of the connecting plate 31 is the same as the diameter of the inner cup shell 12. The connecting plate 31 is used to block the bottom opening of the inner cup shell 12 and can block the bottom opening of the outer cup shell 11.
[0030] In this embodiment, a pressure relief hole 8 is provided on the top inner wall of the electric rotating cup cover 2 and is located on one side of the through hole 5. The pressure relief hole 8 is provided so that the gas inside the cup body can be discharged when the liquid inside the cup body expands due to heat.
[0031] In this embodiment, it should be noted that the lower electrode 3 and the upper electrode 4 can be made of aluminum, and the electric rotating cup body 1 and the electric rotating cup cover 2 can be made of plastic.
[0032] The closure 2 of the present invention is convenient for the user to remove the closure cover 2 from the cup body 1 of the electric cup by means of the connection and cooperation between the external thread 6 and the internal thread, and convenient for the user to screw the closure cover 2 back onto the cup body 1 of the electric cup. The closure 2 can be effectively replaced by the existing flip-top method for opening and closing the closure cover 2, so as to solve the problem that the existing flip-top method requires that the cup body 1 of the electric cup be filled with liquid before the liquid surface can be contacted, and the problem that the liquid is easily overflowed when the lid is buckled when too much liquid is filled is solved. By adopting the screw-top method, when the closure cover 2 is screwed on the top of the cup body 1 of the electric cup, it is only necessary to fill the liquid to the safety line above (the safety line is marked in advance or at the factory inside the cup body 1 of the electric cup), and the liquid is not easy to overflow. By arranging the pressure reducing hole 8 on the cup cover 2 of the electric cup, when the liquid in the cup body 1 of the electric cup expands due to heat, the gas inside the cup body can be discharged, thereby solving the problem that the existing closure cover 2 of the electric cup has no pressure reducing hole and the closure cover 2 of the electric cup will be pushed open.
