DESCRIPTION OF THE INVENTION In order to clearly explain the technical characteristics of the scheme, the scheme will be described by specific implementation mode below. It should be noted that the embodiments in the invention and the features in the embodiments can be combined with each other without conflict. Embodiment 1:
Referring to Figs. 1- 3, the device for culturing animal muscle cells comprises a culture dish body 1 and a dish cover 2, wherein a sealed cavity 101 1s arranged at the lower part of the culture dish body 1, a liquid inlet pipe 102 communicated with the cavity 101 is arranged in the culture dish body 1, and a liquid outlet of the liquid inlet pipe is higher than the liquid level in the culture dish body 1 and the cavity 101. It also includes a container 6 whose liquid storage space communicated with the cavity 101 can be adjusted through one-way valve I.
As the liquid storage space of the container 6 becomes smaller, the liquid in the container 6 can enter the culture dish body 1 through the sealed cavity 101 and the liquid inlet pipe 102. It also comprises a extrusion mechanism for controlling the reduction of the liquid storage space inside the container 6. The extrusion mechanism comprises an extrusion barrel 3 and a sealing piston I 4 arranged in the extrusion barrel 3, and a container 6 is arranged in the extrusion barrel 3 below sealing piston I 4. It also includes a driving mechanism for controlling sealing piston I 4, wherein the driving mechanism comprises a liquid storage barrel 5 connected with the extrusion barre 31, fluid is arranged in the liquid storage barrel 5, the liquid storage barrel 5 is communicated with the extrusion barrel 3 through a fluid flow restriction structure, and an exhaust pipe 7 for exhausting air to the outside of the extrusion barrel 3 is arranged on the extrusion barrel 3 above sealing piston I 4, and a one-way valve IT is arranged on the exhaust pipe 7. The fluid gradually enters the extrusion barrel 3, and the sealing piston I 4 moves downwards under the action of gravity of the fluid.
The liquid storage barrel 5 comprises a lower conical connecting cylinder 501, an upper cylindrical cylinder 502, and a connecting pipe 503 which connects the conical connecting cylinder 501 and the cylindrical cylinder 502 and shrinks toward the axial center, and the fluid flow restriction structure is arranged on the connecting pipe 503. The fluid flow restriction structure 1s a flow restriction valve or a plurality of plugs I 504 each provided with water outlet holes 505, and the inner diameters of the water outlet holes 505 on different plugs I 504 are different. Sealing piston I 4 is fixed on the upper side wall of the extrusion barrel 3 through an elastic part 401. The elastic part 401 can be a spring or a rubber band. The container 6 is integrally arranged with the extrusion barrel 3, the bottom of the extrusion barrel 3 is sealed by a bottom plate, and the container is arranged between the bottom plate of the extrusion barrel 3 and sealing piston I 4. A plurality of liquid inlet pipes 102 are uniformly distributed along the inner wall of the culture dish body 1, and the liquid inlet pipes 102 are all communicated with the cavity
101. Usage: according to the amount of culture solution injected into the culture dish body 1, select a container 6 with appropriate volume, and inject appropriate fluid into the liquid storage barrel 5. The fluid will drip above the sealing piston I 4 through the water outlet hole 505 on the plug I 504. With the passage of time, more and more fluid will accumulate on the sealing piston I 4, and the air in the upper part of the extrusion barrel 3 will be squeezed out through the exhaust valve during the fluid entering. When the weight of the fluid can overcome the friction of sealing piston I 4 and the pulling force of the elastic part 401, sealing piston I 4 will move down, and the space of the container 6 will become smaller in the process of moving down, and the nutrient solution in the container 6 will be squeezed into the cavity 101. With the continuous descent of sealing piston I 4, the culture solution will enter the inside of the culture dish body 1 through the cavity 101 and the liquid inlet pipe 102. The capacity in the container 6 only needs to ensure the amount of adding once.
In addition, the size of the water outlet hole 505 can control the time for adding the nutrient solution into the culture dish body 1. The smaller, the longer the waiting time for adding the nutrient solution.

It also includes a container 6 whose liquid storage space communicated with the cavity 101 can be adjusted through one-way valve I.
As the liquid storage space of the container 6 becomes smaller, the liquid in the container 6 can enter the culture dish body 1 through the sealed cavity 101 and the liquid inlet pipe 102. It also comprises a extrusion mechanism for controlling the reduction of the liquid storage space inside the container 6. The extrusion mechanism comprises an extrusion barrel 3 and a sealing piston I 4 arranged in the extrusion barrel 3, and a container 6 is arranged in the extrusion barrel 3 below sealing piston I 4.
It also includes a driving mechanism for controlling sealing piston I 4, wherein the driving mechanism comprises a liquid storage barrel 5 connected with the extrusion barre 31, fluid is arranged in the liquid storage barrel 5, the liquid storage barrel 5 is communicated with the extrusion barrel 3 through a fluid flow restriction structure, and an exhaust pipe 7 for exhausting air to the outside of the extrusion barrel 3 is arranged on the extrusion barrel 3 above sealing piston I 4, and a one-way valve IT is arranged on the exhaust pipe 7. The fluid gradually enters the extrusion barrel 3, and the sealing piston I 4 moves downwards under the action of gravity of the fluid.
The liquid storage barrel 5 comprises a lower conical connecting cylinder 501, an upper cylindrical cylinder 502, and a connecting pipe 503 which connects the conical connecting cylinder 501 and the cylindrical cylinder 502 and shrinks toward the axial center, and the fluid flow restriction structure is arranged on the connecting pipe 503. The fluid flow restriction structure is a flow restriction valve or a plurality of plugs I 504 each provided with water outlet holes 505, and the inner diameters of the water outlet holes 505 on different plugs I 504 are different.
Sealing piston I 4 is fixed on the upper side wall of the extrusion barrel 3 through an elastic part 401. The elastic part 401 is fixed by a supporting rod 402 fixed on the inner wall of the extrusion barrel 3, the elastic part 401 can be a spring or a rubber band.
The container 6 is integrally arranged with the extrusion barrel 3, the bottom of the extrusion barrel 3 is sealed by a bottom plate, and the container is arranged between the bottom plate of the extrusion barrel 3 and sealing piston I 4.
A plurality of liquid inlet pipes 102 are uniformly distributed along the inner wall of the culture dish body 1, and the liquid inlet pipes 102 are all communicated with the cavity
101. It also includes a discharging mechanism 8 arranged below the culture dish body 1, which comprises a liquid discharging barrel 801 which is arranged below the culture dish body 1 and provided with a plurality of drain hole 103. An annular baffle 104 is arranged below the culture dish body 1 at the periphery of the drain hole 103, and a plug II 804 for blocking the drain hole 103 is arranged on the annular baffle 104. Plug II 804 is arranged below the culture dish body 1 through a spring 805. A sealing piston II 802 is arranged in the liquid discharging barrel 801, and a U-shaped pipe 806 is externally connected to the upper side wall of the liquid discharging barrel
801. The upper and lower outlets of the U-shaped pipe 806 are both communicated with the inside of the liquid discharging barrel 801. A drain port 807 is arranged on the side wall of the liquid discharging barrel 801 below the U-shaped pipe 806, and the thickness of sealing piston II 802 is less than the minimum distance between the two outlets. The lower end of the liquid discharging barrel 801 is sealed, and a piston rod 803 is concentrically arranged on sealing piston II 802, and the piston rod 803 is arranged on the liquid discharging barrel 801 through threaded connection. Usage: the discharging mechanism 8 is adjusted in advance so that the sealing piston 802 is located between the two outlets, due to the existence of the u-shaped pipe 806 and the drain port 807, the discharging barrel 801 is communicated with the outside air, at this time, the drain hole 103 is completely blocked by the plug II 804 under the action of the spring 805.
Then, according to the amount of culture solution injected into the culture dish body 1, a container 6 with appropriate volume 1s selected, and an appropriate fluid is injected into the liquid storage barrel 5. The fluid will drip above the sealing piston I 4 through the water outlet hole 505 on the sealing plug I 504. With the passage of time, more and more fluid will accumulate on the sealing piston I 4, and the air in the upper part of the extrusion barrel 3 will be squeezed out through the exhaust valve during the fluid entering. When the weight of the fluid can overcome the friction of sealing piston I 4 and the pulling force of the elastic part 401, sealing piston I 4 will move down, and the space of the container 6 will become smaller in the process of moving down, and the nutrient solution in the container 6 will be squeezed into the cavity 101. With the continuous descent of sealing piston I 4, the culture solution will enter the inside of the culture dish body 1 through the cavity 101 and the liquid inlet pipe 102. The capacity in the container 6 only needs to ensure the amount of adding once. In addition, the size of the water outlet hole 505 can control the time for adding the nutrient solution into the culture dish body 1. The smaller, the longer the waiting time for adding the nutrient solution.
When it is necessary to replace the culture solution or discharge the waste culture solution, the screw 803 can be rotated to make sealing piston II 802 move down. When the outlet below the U-shaped pipe 806 is blocked, there is no air inlet above the liquid discharging barrel 801. If the screw 803 is continuously rotated, sealing piston II 802 moves down continuously, and the upper space of the liquid discharging barrel 801 gradually increases, while the air mass remains unchanged and the air pressure decreases. When the air pressure at the upper part of the culture dish body 1 can overcome the pulling force of the spring 805, the plug II 804 is pushed open, and the waste liquid flows to the top of the sealing piston 802 through the drain hole 103. Because the inner diameter of the drain hole 103 is small, the tissue particles will not flow out and stick to the inner wall of the culture dish body 1, which also increases the difficulty of flowing out.
Sealing piston II 802 continues to descend.
When the drain port 807 is higher than sealing piston II 802, the waste liquid flows out through the drain port 807, and the spring 805 drives the plug II 804 to reset.
