Description

Technical Field

[0001] This utility model belongs to the field of cell culture medium technology, specifically relating to an automatic cell culture medium dispensing device. Background Technology

[0002] In practical applications of cell culture, adding culture medium to a large number of cell storage bottles is a routine task. However, during the addition process, the storage bottles may tilt or tip over because they are not fixed in place. Moreover, the addition of culture medium often needs to be carried out at a constant and continuous rate, which cannot be guaranteed manually. Furthermore, since the culture medium needs to be added at intervals, precipitation may occur during these intervals, resulting in uneven mixing of the culture medium. Uneven culture medium after addition will affect the growth and reproduction efficiency of cells. Utility Model Content

[0003] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide an automatic cell culture medium dispensing device.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] An automatic cell culture medium dispensing device includes a base, two ear plates integrally connected to the base, the ear plates having fixing holes, a T-slot on the base, a base movably placed in the T-slot, a spring assembly installed between one side of the base and the T-slot, and a vibration motor installed on the other side of the base where the spring assembly is installed.

[0006] The base is equipped with a transparent feeding cylinder. The output end of the vibration motor contacts the outer wall of the transparent feeding cylinder. A pneumatic pump is installed at one end of the transparent feeding cylinder, and a flexible hose is installed at the other end. The output end of the flexible hose is connected to a discharge pipe, which is fixedly installed on the base. A first electric valve is installed on the discharge pipe. A fixed cylinder is connected to the top of the transparent feeding cylinder. A second electric valve is installed on the fixed cylinder. A fixing cap is threaded to the outside of the input end of the fixed cylinder. Four pressure plates are integrally connected to the input end of the fixed cylinder. The four pressure plates are evenly connected to the input end of the fixed cylinder, and there is a fork between adjacent pressure plates. A storage bottle is installed on the fixed cylinder.

[0007] Furthermore, the T-slot is fitted with a baffle, a design that effectively prevents the base from moving out of the T-slot.

[0008] Furthermore, the output end of the vibration motor is equipped with a shock-absorbing soft rubber pad. This design reduces noise and prevents vibration from damaging the contact surface.

[0009] Furthermore, the transparent feeding cylinder is equipped with a degassing pipe, and the degassing pipe is equipped with a third electric valve. This design prevents the culture medium in the storage bottle from being unable to be obtained due to high air pressure inside the transparent feeding cylinder.

[0010] Furthermore, the inner surface of the tablet is fitted with a soft contact rubber. This design allows the soft contact rubber to buffer the pressure when pressure is applied by the fixing cap, while also increasing friction and preventing damage to the output end of the storage bottle.

[0011] The beneficial effects of using this utility model are as follows:

[0012] The structural design of this utility model, with the cooperation of the fixing cap and the pressure plate, can fix the output end of the storage bottle, so that the storage bottle will not tip over due to shaking;

[0013] By adopting the structural design of this utility model, the purpose of uniform quantitative injection can be achieved by controlling the intermittent quantitative air supply of the air pressure pump. It is simple, convenient, accurate and labor-saving to use.

[0014] With the structural design of this utility model, the culture medium in the storage bottle will be shaken apart by the vibration of the vibrating motor, thus making it less prone to sedimentation. Attached Figure Description

Detailed Implementation

[0022] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figures 1-4 As shown, the present invention provides an automatic cell culture medium dispensing device, including a base 1, two ear plates 2 integrally connected to the base 1, the ear plates 2 having fixing holes 3, the base 1 having a T-shaped groove 4, a base 5 movably placed in the T-shaped groove 4, a spring assembly 6 installed between one side of the base 5 and the T-shaped groove 4, and a vibration motor 7 installed on the other side of the base 1 where the spring assembly 6 is installed.

[0024] A transparent feeding cylinder 8 is installed on the base 5. The output end of the vibration motor 7 is in contact with the outer wall of the transparent feeding cylinder 8. A pneumatic pump 9 is installed at one end of the transparent feeding cylinder 8, and a flexible hose 10 is installed at the other end of the transparent feeding cylinder 8. The output end of the flexible hose 10 is connected to a discharge pipe 11. The discharge pipe 11 is fixedly installed on the base 1. A first electric valve 12 is installed on the discharge pipe 11. A fixed cylinder 13 is connected to the top of the transparent feeding cylinder 8. A second electric valve 14 is installed on the fixed cylinder 13. A fixed cap 15 is threadedly connected to the outside of the input end of the fixed cylinder 13. Four pressure plates 16 are integrally connected to the input end of the fixed cylinder 13. The four pressure plates 16 are evenly connected to the input end of the fixed cylinder 13. There is a fork 17 between two adjacent pressure plates 16. A storage bottle 18 is installed on the fixed cylinder 13.

[0025] In this embodiment, when using an automatic cell culture medium dispensing device, the storage bottle 18 is inserted into the fixing cylinder 13, and then the fixing cap 15 is rotated. Due to the effect of the thread, the fixing cap 15 moves upward, thereby squeezing the pressure plate 16. Under the effect of the pressure plate 16, the storage bottle 18 is fixed, making it difficult for the storage bottle 18 to slide and detach.

[0026] When the first electric valve 12 is closed and the second electric valve 14 is opened, the material in the storage bottle 18 flows into the transparent feeding cylinder 8. After the transparent feeding cylinder 8 is filled, the second electric valve 14 is closed and the first electric valve 12 is opened. The air pressure pump 9 runs, and under the pressure of the air, the material passes through the hose 10 and is discharged from the discharge pipe 11, thus achieving the purpose of automatic filling. The intermittent quantitative operation of the air pressure pump 9 achieves the effect of uniform quantitative filling.

[0027] During filling or before feeding material into the transparent feeding cylinder 8, the vibrating motor 7 runs, causing the base 5 to move within the base 1. Under the effect of the spring assembly 6, the base 5 will rebound, thereby achieving the reciprocating vibration of the base 1, which in turn causes the storage bottle 18 mounted on the upper side to vibrate, preventing the material in the storage bottle 18 from settling. Moreover, with the effect of the hose 10 and the cooperation of the discharge pipe 11 fixedly mounted on the base 1, the vibration of the transparent feeding cylinder 8 will not affect the material filling at the output end of the discharge pipe 11.

[0028] The preferred design is to install a baffle 19 in the T-slot 4. This design effectively prevents the base 5 from moving out of the T-slot 4. In fact, a structure to prevent the base 5 from moving out of the T-slot 4 can also be considered depending on the specific circumstances.

[0029] The output end of the preferred vibration motor 7 is equipped with a shock-absorbing soft rubber pad. This design reduces noise and prevents vibration from damaging the contact surface. In fact, measures to prevent vibration from damaging the contact surface can also be considered depending on the specific situation.

[0030] The transparent feeding cylinder 8 is preferably equipped with a degassing pipe 20, and the degassing pipe 20 is equipped with a third electric valve 21. This design prevents the culture medium in the storage bottle 18 from being unable to be obtained due to high air pressure inside the transparent feeding cylinder. In fact, a structure that ensures the material enters the transparent feeding cylinder 8 can also be considered depending on the specific situation.

[0031] The inner surface of the preferred pressing plate 16 is fitted with a contact soft rubber. This design allows the contact soft rubber to buffer the pressure when pressure is applied by the fixing cap 15, while also increasing the friction. It also prevents damage to the output end of the storage bottle 18. In fact, measures to prevent damage to the output end of the storage bottle 18 can be considered depending on the specific circumstances.

[0032] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
