Description

Technical Field

[0001] The invention relates to the field of biology, and more particularly to a constant temperature incubation shaking table device. Background Art

[0002] The constant temperature incubation shaker is a desktop oscillating incubator that integrates temperature control and oscillation functions. The constant temperature incubation shaker has precise temperature control capabilities and can provide a stable temperature environment to adapt to different experimental needs. It also combines low-frequency and high-amplitude oscillation functions to perform three-dimensional or two-dimensional shaking of the container at a constant temperature, which helps to improve the mixing efficiency and uniformity of the sample. It is widely used in biotechnology, microbiology, medical analysis and other fields.

[0003] When culturing cells or bacteria, the constant temperature incubator shaker supports the growth of cells or microorganisms by providing a constant temperature environment and moderate shaking to promote uniform distribution of nutrients and gas exchange;

[0004] The Chinese patent with authorization announcement number: CN215693731U discloses a desktop intelligent temperature-controlled 3D shaker. Through the matching design of the first servo motor and the gear, the refrigeration unit can rotate and reciprocate in the horizontal and vertical directions, which can achieve precise temperature control at multiple positions, reduce liquid residue, and achieve better incubation effect, further improving work efficiency.

[0005] Although the above patent can realize rotation and reciprocating swing, it still has the following shortcomings:

[0006] However, when using an incubation shaker to cultivate microbial growth, due to the different densities of the microorganisms and nutrients, the microorganisms and nutrients will be stratified, resulting in poor mixing effect, and when the constant temperature incubation shaker drives the reagent bottle to shake, some nutrients will adhere to the inner wall of the container, resulting in a decrease in the nutrient content in the culture solution, prolonging the incubation time, and resulting in low work efficiency.

[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention. Embodiment 1:

[0047] See also Figures 1 to 13 A constant temperature incubation shaker device comprises a shell 1 of a heat-insulating material and a reagent bottle 2; a sealing door 3 is hinged on the shell 1, a base 4 is arranged inside the shell 1, and a first servo motor 5 is arranged on the base 4. Adjusting the rotation direction and rotation angle of the first servo motor 5 by a control program is a prior art and will not be described in detail. A tray 6 is arranged on the output end of the first servo motor 5;

[0048] An elastic bellows 7 with an opening at the bottom end is movably provided in the housing 1, and a conduit 8 is inserted into the side wall of the elastic bellows 7, and the conduit 8 is used to extract the liquid in the elastic bellows 7; a limiting frame 9 is provided in the elastic bellows 7, and the limiting frame 9 is used to limit the bottom position of the conduit 8, and a control component for controlling the movement of the elastic bellows 7 is provided in the housing 1, wherein the central axis of the elastic bellows 7 is offset from the central axis of the reagent bottle 2;

[0049] A floating block 10 is movably sleeved on the elastic bellows 7, a connecting rod 11 is provided on the floating block 10, a circular tube 12 is installed on the connecting rod 11, holes are evenly opened on the side wall of the circular tube 12, and an elastic tube 13 is installed between the circular tube 12 and the conduit 8;

[0050] A mounting frame 14 is provided in the housing 1 , on which a gas nozzle 15 is evenly and obliquely mounted. The gas nozzle 15 is used to transfer substances attached to the inner wall of the reagent bottle 2 , and a gas supply component cooperating with the gas nozzle 15 is provided in the housing 1 .

[0051] The control component includes a switch 16 arranged on the top wall of the tray 6, the switch 16 corresponds one-to-one to the reagent bottle 2, telescopic rods 17 are evenly installed on the inner top wall of the outer shell 1, the telescopic rods 17 correspond one-to-one to the switch 16, the switch 16 is electrically connected to the corresponding telescopic rod 17, and the elastic bellows 7 is arranged on the output end of the telescopic rod 17.

[0052] The limiting frame 9 is installed at the bottom of the inner wall of the elastic bellows 7, the bottom end of the conduit 8 is installed on the top wall of the limiting frame 9, the top end of the conduit 8 is inserted on the side wall of the elastic bellows 7, and the top end of the conduit 8 is located above the liquid level in the reagent bottle 2.

[0053] The mounting frame 14 is sleeved on the output end of the telescopic rod 17, and the output end of the air nozzle 15 is tilted downward; the air supply assembly includes a connecting block 18 rotatably mounted on the output end of the telescopic rod 17, and the elastic bellows 7 is mounted on the bottom wall of the connecting block 18, and the connecting block 18 is made of elastic material; the elastic coefficient of the connecting block 18 is smaller than the elastic coefficient of the elastic bellows 7;

[0054] A cavity 19 is formed on the connection block 18 , and an intake valve 20 and an exhaust valve 21 are embedded on the side wall of the cavity 19 . The input end of the air nozzle 15 is connected to the exhaust valve 21 , and the input end of the intake valve 20 is connected to the elastic bellows 7 .

[0055] First, remove the reagent bottle 2 from the tray 6 and fill it with a mixed liquid of the microorganisms to be incubated and nutrients, and then place the reagent bottle 2 at the specified position. At this time, the reagent bottle 2 applies pressure to the switch 16, so the switch 16 controls the corresponding telescopic rod 17 to extend. At this time, the telescopic rod 17 drives the elastic bellows 7 to insert below the liquid surface in the reagent bottle 2. At this time, part of the liquid is located in the elastic bellows 7, and under the action of the limit frame 9, when the bottom end of the elastic bellows 7 is in contact with the inner bottom wall of the reagent bottle 2, the distance between the bottom end of the conduit 8 and the inner bottom wall of the reagent bottle 2 is a fixed value, so the conduit 8 can absorb liquid from the elastic bellows 7, and then close the sealing door 3, and start the heating wire in the outer shell 1, so that the inside of the outer shell 1 can be heated. Under the action of the outer shell 1 made of insulating material, the reagent bottle 2 is in a constant temperature environment.

[0056] Then the first servo motor 5 is started, and the first servo motor 5 drives the tray 6 to rotate back and forth, that is, the tray 6 swings around the center of the first servo motor 5 with a specified amplitude, and the liquid in the reagent bottle 2 shakes accordingly, so that the nutrients therein can be evenly mixed.

[0057] Since the telescopic rod 17 is in a stationary state, when the tray 6 is in a clockwise rotation state, the elastic bellows 7 will be squeezed. At this time, the air pressure in the elastic bellows 7 increases, so the liquid at the bottom layer in the elastic bellows 7 will be discharged along the conduit 8, thereby achieving the effect of extracting the liquid at the bottom layer in the reagent bottle 2 to the top layer; when the tray 6 rotates counterclockwise, the bottom of the elastic bellows 7 is out of contact with the bottom wall of the reagent bottle 2. At this time, the liquid in the reagent bottle 2 will enter the elastic bellows 7 again, and so on. The elastic bellows 7 can continue to work to transfer the bottom liquid to the top layer, thereby improving the mixing effect.

[0058] Since the outer wall of the elastic bellows 7 has wave crests, relative displacement occurs between two adjacent wave crests during the stretching or compression of the elastic bellows 7, which can further drive the liquid to slosh, thereby further improving the mixing effect of the substances in the liquid.

[0059] The float 10 always floats on the liquid surface, so under the joint action of the connecting rod 11 and the elastic tube 13, the annular tube 12 is always located above the liquid surface. Therefore, when different amounts of liquid are loaded into the reagent bottle 2, the bottom liquid can be discharged to the top layer, which plays a role in expanding the application range of the device; and by evenly opening holes on the annular tube 12, the diffusion range of the liquid discharged from the annular tube 12 can be expanded, increasing the contact area between the bottom liquid and the top liquid, which plays a role in further improving the mixing efficiency.

[0060] The switch 16 is a time-delay switch, and the time-delay switch and the electric heating wire heating are prior arts and will not be described in detail.

[0061] Since the elastic coefficient of the connecting block 18 is smaller than the elastic coefficient of the elastic bellows 7, when the elastic bellows 7 is squeezed, the connecting block 18 is deformed first. At this time, the gas in the cavity 19 is discharged outward through the exhaust valve 21 and the air nozzle 15. The gas discharged from the air nozzle 15 impacts the inner wall of the reagent bottle 2, and the air nozzle 15 is tilted. Therefore, when the airflow contacts the inner wall of the reagent bottle 2, most of the airflow will flow downward along the inner wall of the reagent bottle 2 and blow the liquid adhered to the inner wall of the reagent bottle 2 downward, so that the liquid in the reagent bottle 2 contains a sufficient amount of nutrients.

[0062] When the tray 6 rotates in the opposite direction and the elastic bellows 7 loses contact with the bottom wall of the tray 6, the connecting block 18 is restored. At this time, the cavity 19 draws air from the elastic bellows 7 through the air inlet valve 20, thereby providing a negative pressure environment for the elastic bellows 7 and increasing the content of the bottom liquid entering the elastic bellows 7.

[0063] like Figure 7 As shown, a guide rod 22 is installed on the inner wall of the annular tube 12, a spoiler 23 is slidably installed on the guide rod 22, an elastic rope 24 is installed between the spoiler 23 and the inner wall of the annular tube 12, and an arc-shaped protrusion 25 is provided on the side wall of the spoiler 23 close to the elastic rope 24.

[0064] A protective cover 26 is fixedly mounted on the top of the side wall of the spoiler 23 and is slidably matched with the top wall of the hole; the protective cover 26 is U-shaped with an opening facing downward, and the ratio of the volume of the cavity 19 to the volume of the hole is 50 to 80.

[0065] By adopting the above technical solution, when the annular tube 12 discharges liquid through the hole, the liquid impacts the spoiler 23, and the spoiler 23 moves along the guide rod 22 and the hole until the spoiler 23 is out of contact with the hole, at which time the elastic rope 24 is in a stretched state, and the spoiler 23 is located at the end of the guide rod 22;

[0066] At the same time, the liquid discharged from the hole impacts the bump 25 on the surface of the spoiler 23. Since the surface of the bump 25 is arc-shaped, the liquid impacting the bump 25 will be scattered along the arc surface. By setting a U-shaped protective cover 26 with an opening downward, the splashing direction of the liquid can be limited to prevent the liquid from splashing upward or splashing onto the inner wall of the reagent bottle 2, further expanding the contact area between the liquid discharged from the hole and the top layer of liquid, thereby improving the mixing effect.

[0067] When the elastic bellows 7 loses contact with the inner bottom wall of the reagent bottle 2, the annular tube 12 stops discharging liquid outward. At this time, the elastic rope 24 recovers and pulls the spoiler 23 to reset. During the reset of the spoiler 23, the spoiler 23 slides along the hole. At this time, the gas in the hole is pushed back into the annular tube 12, so that the liquid attached to the inner wall of the annular tube 12, the elastic tube 13 and the conduit 8 can be rinsed clean, which facilitates cleaning.

[0068] By making the volume of the cavity 19 larger than the volume of the hole, the gas pushed back into the elastic bellows 7 by the spoiler 23 is prevented from affecting the liquid absorption of the elastic bellows 7 .

[0069] like Figure 7 As shown, the inner bottom wall of the annular tube 12 is an inclined surface, and the top end of the elastic tube 13 is located at the lowest point inside the annular tube 12 .

[0070] By adopting the above technical solution, by setting the bottom wall of the annular tube 12 as an inclined surface, the liquid remaining in the annular tube 12 can flow back along the elastic tube 13 and the conduit 8 during the resetting of the spoiler 23, thereby preventing nutrients from remaining in the annular tube 12.

[0071] like Figure 8 As shown, an external threaded sleeve 27 is inserted on the top wall of the elastic bellows 7 , and a nut 28 threadedly connected to the external threaded sleeve 27 is fixedly mounted on the bottom wall of the connecting block 18 .

[0072] By adopting the above technical solution, under the action of the external threaded sleeve 27 and the nut 28, the elastic bellows 7 and the connecting block 18 can be disassembled, thereby facilitating the cleaning of the elastic bellows 7, the catheter 8, and the annular tube 12, thereby preventing cross contamination during the incubation process; and the air inlet valve 20 can normally inhale air from the elastic bellows 7 through the external threaded sleeve 27.

[0073] like Figure 5 As shown, a suction cup 29 is rotatably mounted on the top wall of the tray 6, and a second servo motor 30 whose output end is connected to the suction cup 29 is mounted on the bottom wall of the tray 6;

[0074] The housing 1 is provided with a control module 31 , a calculation module 32 and a judgment module 33 , and the bottom wall of the limiting frame 9 is provided with a pressure detection module 34 .

[0075] By adopting the above technical solution, during the working process, the reagent bottle 2 is placed on the surface of the suction cup 29, and the suction cup 29 tightly absorbs the reagent bottle 2. Therefore, when the detection module detects that the elastic bellows 7 is out of contact with the inner bottom wall of the reagent bottle 2, a signal is sent to the control module 31. At this time, the control module 31 controls the second servo motor 30 to work, thereby driving the reagent bottle 2 to rotate, so that the inner wall of the reagent bottle 2 is successively close to the elastic bellows 7, thereby improving the mixing effect of the liquid and the cleaning effect of the inner wall of the reagent bottle 2.

[0076] The pressure detection module 34 is a pressure sensor, which is used to detect the pressure between the elastic bellows 7 and the inner bottom wall of the reagent bottle 2, and send the value to the calculation module 32. The pressure sensor is a prior art and will not be described in detail.

[0077] The calculation module 32 stores the pressure value detected by the pressure detection module 34 when the tray 6 is in a horizontal state and the telescopic rod 17 is in an extended state, and the calculation module 32 sends the calculated data to the judgment module 33;

[0078]

[0079] Wherein, A is the difference between the pressure value actually detected by the pressure detection module 34 and the pressure value stored therein;

[0080] P0 is the pressure value detected by the pressure detection module 34 when the tray 6 is in a horizontal state and the telescopic rod 17 is in an extended state, that is, the pressure value stored in the calculation module 32;

[0081] P1 is the pressure value detected in real time by the pressure detection module 34;

[0082] After receiving the data, the judgment module 33 judges the data and sends the judgment result to the control module 31;

[0083] When A≥0, the control module 31 controls the second servo motor 30 not to work;

[0084] When A<0, the control module 31 controls the output end of the second servo motor 30 to rotate;

[0085] When the control module 31 controls the second servo motor 30 to rotate:

[0086]

[0087] Wherein, α is the degree of the sector formed by the path of the tray 6 when it rotates from the horizontal state to the maximum tilt angle, that is, the preset swing angle, ω1 is the preset speed of the first servo motor 5; t is the time required for the first servo motor 5 to rotate α degrees;

[0088]

[0089] Wherein, ω2 is the preset speed of the second servo motor 30; S is the rotation angle of the output end of the second servo motor 30, and 0°<S<360°, and the rotation angle S of the output end of the second servo motor 30 is manually controlled.

[0090] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
