[0031] Reference below Figures 1-3 The invention describes an incubator bionic breathing system according to an embodiment of the invention.

[0032] like Figures 1-3 As shown, the incubator bionic breathing system includes an incubator body 110 and a bionic breathing mechanism 200 connected to the incubator body 110, and the two are connected through a pipeline (not shown in the drawings). It also includes a servo drive mechanism 300, which is arranged outside the incubator body 110, close to the position of the bionic breathing mechanism 200 and is transmission-connected to the bionic breathing mechanism 200, and is used to control the working state of the bionic breathing mechanism 200. In this embodiment, the bionic breathing mechanism 200 and the servo drive mechanism 300 are both arranged at the rear of the incubator body 110.

[0033] The bionic breathing mechanism 200 includes a cylinder 210 and a piston 220 sliding in the cylinder 210. The cylinder 210 is connected to the culture box 110. The piston 220 is connected to the servo drive mechanism 300. The servo drive mechanism 300 accurately controls the position of the piston 220 in the cylinder 210. The position of the piston 220 in the cylinder 210 determines the volume of the air cavity of the cylinder 210. The servo drive mechanism 300 drives the piston 220 to move accurately, and the stroke of the piston 220 can be effectively controlled, so as to achieve the effect of accurately controlling the gas volume in the cylinder 210, thereby adjusting the gas pressure in the culture box 110, and the variable control effect is better, which improves the culture stability of the culture box 110.

[0034] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the servo drive mechanism 300 and the bionic breathing mechanism 200 are both fixedly mounted on a mounting seat 120 , and the positions of the servo drive mechanism 300 and the bionic breathing mechanism 200 are relatively fixed.

[0035] Specifically, the servo drive mechanism 300 and the bionic breathing mechanism 200 are fixedly mounted on the same mounting base 120 so that the two are relatively stationary, ensuring that the servo drive mechanism 300 controls the piston 220 to remain stable during movement and avoiding shaking and displacement.

[0036] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the volume ratio of the cavity volume of the cylinder 210 to the volume of the culture box 110 is 0.03 to 0.04. Specifically, in order to improve the response speed of the gas pressure control in the culture box 110, the volume ratio between the cylinder 210 and the culture box 110 is in the range of 0.03 to 0.04, and the servo drive mechanism 300 can achieve accurate gas pressure regulation.

[0037] Furthermore, the volume of the cylinder 210 is 0.4L to 0.6L, while the volume of the culture box 110 is between 14L and 16L, which meets the conventional small culture environment and ensures the effect of the servo drive mechanism 300 to adjust the gas pressure in the culture box 110 .

[0038] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the piston 220 is provided with at least two circles of sealing grooves 221 , and sealing rings 222 are provided in the sealing grooves 221 . The sealing rings 222 are used to seal the connection gap between the piston 220 and the inner wall of the cylinder body 210 .

[0039] In this embodiment, two circles of sealing grooves 221 are provided on the periphery of the piston 220, and a sealing ring 222 made of rubber material is sleeved on the sealing groove 221. The servo drive mechanism 300 pushes the piston 220 to move, and the sealing ring 222 is limited in the sealing groove 221, so that the sealing ring 222 and the piston 220 slide synchronously to change the cavity volume of the cylinder body 210.

[0040] Furthermore, the diameter of the piston 220 is 110 mm to 130 mm. The cross-sections of the piston 220 and the cylinder 210 are both circular. In other embodiments, the cylinder 210 and the piston 220 can also adopt a square structure. It should be understood that, without departing from the basic concept of the utility model, the cross-sectional shapes of the cylinder 210 and the piston 220 can be flexibly changed, which should be regarded as within the protection scope defined by the utility model.

[0041] In some embodiments of the present invention, Figures 1-3 As shown, the servo drive mechanism 300 includes a drive assembly 320 and an output shaft 310 . The output shaft 310 is connected to the piston 220 . The drive assembly 320 is in transmission connection with the output shaft 310 . The output shaft 310 pushes the piston 220 to reciprocate in the cylinder body 210 .

[0042] Specifically, the servo drive mechanism 300 usually includes a built-in encoder, which can achieve closed-loop control, that is, adjust the rotational speed and position through feedback signals to achieve high-precision control. The output of the drive component 320 can be adjusted according to the feedback information to adjust the position of the output shaft 310, so as to adjust the specific position of the piston 220 through the output shaft 310.

[0043] Existing incubators usually rely on internal sensors to detect the air pressure inside the incubator. When the air pressure inside the incubator is lower than the set value, the ordinary piston 220 structure is used to increase the air pressure inside the incubator, and it stops working when the specified value is reached. However, its working effect cannot achieve precise control, the adjustment accuracy is low, and it cannot meet the more stringent experimental test environment.

[0044] The servo drive mechanism 300 of this embodiment uses a servo system to precisely control the position of the piston 220 in the cylinder block 210, thereby achieving high-precision adjustment of the air pressure in the incubator, and the adjustment accuracy is improved by an order of magnitude.

[0045] In some embodiments of the present utility model, it includes a control component (not shown in the drawings). The control component is provided with a pressure sensor (not shown in the drawings). The pressure sensor is arranged inside the incubator body 110. The pressure sensor and the servo drive mechanism 300 are respectively electrically connected to the control component. The control component can compare the set air pressure value with the real-time value of the pressure sensor inside the incubator body 110. When the value of the pressure sensor is inconsistent with the set value, it controls the servo drive mechanism 300 to adjust the operation of the piston 220, so that the air pressure inside the incubator body 110 is consistent with the set value. Due to the use of a servo system, precise control of the air pressure in the incubator body 110 can be achieved, ensuring the stability of the environment inside the incubator and better control variable effect.

[0046] In some embodiments of the present utility model, such as Figure 2 and Figure 3 shown, the axes of the output shaft 310, the piston 220, and the cylinder block 210 overlap. The torque exerted by the output shaft 310 on the piston 220 is effectively increased, and the force on the piston 220 is more uniform.
