Description

Technical Field

[0001] This application relates to the technical field of incubators, and particularly to a carbon dioxide shaking incubator with semiconductor refrigeration. Background Art

[0002] A carbon dioxide shaking incubator is a culture container used for cell culture, fermentation, hybridization, biochemistry, cell tissue research and other work. Through the cooperation of an oscillation module and a carbon dioxide module, the incubator can have an oscillation environment and a carbon dioxide environment at the same time, and is suitable for cultures with high requirements for both carbon dioxide and oscillation.

[0003] However, in the existing carbon dioxide shaking incubator, the oscillation plate inside is driven by a cam. Due to the small eccentric displacement of the cam, the oscillation amplitude of the oscillation plate is small, which greatly reduces the culture quality and culture efficiency of the cultures. Summary of the Invention

[0011] Preferably, the transmission module further includes two fourth pulleys provided on the first oscillation base and located on both sides of the width direction of the second oscillation base. The two fourth pulleys are arranged close to the first end, and the two rope bodies are respectively drivingly connected to the two fourth pulleys.

[0012] By adopting the above technical solution, the first oscillation base can stably move along the length direction of the oscillation disk under the cooperation of the two second pulleys, the pulling rope and the two fourth pulleys. It can not only further improve the oscillation stability of the oscillation disk, but also the two fourth pulleys can correct the movement direction of the pulling rope to prevent the first oscillation base from shifting during the movement.

[0013] Preferably, the oscillation assembly further includes a base arranged along the length direction of the oscillation disk. The two second pulleys are respectively provided at both ends of the length direction of the base, and the first oscillation base is slidably arranged on the base along the length direction of the base.

[0014] By adopting the above technical solution, the first oscillation base can be carried on the base, effectively improving the moving stability of the first oscillation base.

[0016] By adopting the above technical solution, the circumferential end portions of the oscillation disk can be respectively connected to the transmission disk through a plurality of transmission shafts, which can not only improve the installation strength of the oscillation disk, but also reduce the transmission loss between the transmission disk and the vibration disk.

[0017] Preferably, an oscillation box for accommodating the oscillation assembly is further arranged in the box body, a plurality of transmission openings are formed in the upper side wall of the oscillation box, and the plurality of transmission shafts are respectively and correspondingly inserted into the plurality of transmission openings.

[0018] By adopting the above technical solution, the oscillation assembly can be accommodated in the oscillation box to prevent the culture on the oscillation disk from falling into the oscillation assembly and affecting the operation of the oscillation assembly; meanwhile, the transmission openings can make way for the transmission shafts, avoiding interference of the oscillation box with the transmission between the oscillation assembly and the oscillation disk.

Detailed implementation mode

[0028] The following will further elaborate on the present invention in conjunction with the appended Figures 1-4 drawings.

[0029] In the description of the present invention, it should be understood that for the orientation description, such as the orientation or positional relationship indicated by up, down, front, back, left, right, etc., is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0030] Refer to Figures 1-4 As shown, a semiconductor refrigeration carbon dioxide shaking incubator is shown, which includes a vertically arranged box body 1, a semiconductor module 2 and a carbon dioxide module 3 provided on the box body 1, a stainless steel inner container 8 provided in the box body 1, two shelves 9 arranged vertically and horizontally in the inner container 8, and a shaking plate 4 arranged horizontally and below the shelves 9. Among them, the semiconductor module 2 is provided on one side of the box body 1, a box door 11 is provided on the other side of the box body 1, the direction from the semiconductor module 2 to the box door 11 is the width direction of the shaking plate 4, and the direction perpendicular to the width direction is the length direction of the shaking plate 4. Both the width direction and the length direction are horizontal directions. The semiconductor module 2 is a Peltier thermoelectric semiconductor refrigeration device in the prior art, which can refrigerate efficiently and keep a low-temperature environment in the inner container 8. Compared with compression refrigeration, the energy consumption is reduced by more than 85%; the carbon dioxide module 3 includes a gas inlet for introducing carbon dioxide and a filter provided at the gas inlet, and the gas inlet is communicated with the inner container 8; an air duct 10 is opened on the box body 1, one end of the air duct 10 is communicated with the semiconductor module 2 and the other end is communicated with the inner container 8.

[0031] In this embodiment, in combination with Figure 2 As shown, a shaking assembly 5 is further provided below the shaking plate 4. The shaking assembly 5 includes a base 55 arranged along the length direction of the shaking plate 4, a first shaking seat 51 movably arranged on the base 55 along the length direction of the shaking plate 4, a second shaking seat 52 movably arranged on the first shaking seat 51 along the width direction of the shaking plate 4, a transmission module 53 for driving the first shaking seat 51 and the second shaking seat 52 to move, and a driving module 54 for driving the transmission module 53 to operate. The shaking plate 4 is carried on the second shaking seat 52.

[0032] After placing the culture on the oscillating tray 4, the cooperation of the driving module 54 and the transmission module 53 can drive the first oscillating seat 51 and the second oscillating seat 52 to move along the length direction and the width direction of the oscillating tray 4 respectively, so that the oscillating tray 4 can reciprocally oscillate along its own length direction and width direction under the cooperation of the first oscillating seat 51 and the second oscillating seat 52, effectively increasing the oscillation amplitude of the oscillating tray 4 and improving the culture quality and culture efficiency of the culture.

[0033] In this embodiment, as shown in Figure 3 , the length direction of the second oscillating seat 52 is the same as the width direction of the oscillating tray 4. The two ends of the length direction of the second oscillating seat 52 are the first end and the second end respectively. The transmission module 53 includes a first pulley 531 provided at the first end, a pulling rope 532 drivingly connected to the first pulley 531, two third pulleys 533 provided on the first oscillating seat 51 and located on both sides of the width direction of the second oscillating seat 52, and two fourth pulleys 534 provided on the first oscillating seat 51 and located on both sides of the width direction of the second oscillating seat 52; the driving module 54 includes two second pulleys 541 respectively provided at both ends of the length direction of the base 55, and two driving members 542 respectively used to drive the two second pulleys 541 to rotate. The driving member 542 is a stepping motor.

[0034] Wherein, the rotation axis of the first pulley 531 extends along the vertical direction. The two third pulleys 533 are arranged close to the second end, the two fourth pulleys 534 are arranged close to the first end. The pulling rope 532 includes two rope bodies respectively located on both sides of the first pulley 531. The two rope bodies are respectively connected to both side parts of the second end. Each rope body sequentially winds around the third pulley 533, the second pulley 541, the fourth pulley 534 and the first pulley 531 along the direction from the second end to the first end.

[0035] In this way, the first oscillating seat 51 and the second oscillating seat 52 can stably move under the transmission cooperation of the first pulley 531, the second pulley 541, the third pulley 533, the fourth pulley 534 and the pulling rope 532, effectively improving the oscillation stability of the oscillating tray 4 and preventing the culture on the oscillating tray 4 from falling during the oscillation process; moreover, the two third pulleys 533 and the two fourth pulleys 534 are respectively located at the four ends of the first oscillating seat 51, and the two can cooperate with each other and correct the movement direction of the pulling rope 532 to prevent the first oscillating seat 51 and the second oscillating seat 52 from shifting during the movement.

[0036] When it is necessary to drive the oscillating disk 4 to oscillate, only two stepper motors need to be started. The two stepper motors can rotate forward and reverse periodically to achieve the reciprocating oscillation of the oscillating disk 4. Specifically, when it is necessary to control the oscillating disk 4 to oscillate along its width direction, only the rotation directions of the two second pulleys 541 need to be opposite. The two second pulleys 541 can respectively pull the same end of the second oscillating seat 52 through two rope bodies during their respective rotations to achieve the movement of the second oscillating seat 52; when it is necessary to control the oscillating disk 4 to oscillate along its length direction, only the rotation directions of the two second pulleys 541 need to be the same. The two second pulleys 541 can respectively pull different ends of the second oscillating seat 52 through two rope bodies during their respective rotations, thereby pulling the second oscillating seat 52 to move along the length direction of the oscillating disk 4 to achieve the movement of the first oscillating seat 51.

[0037] In some other embodiments, one of the two second pulleys 541 can also be driven alone. In this way, the movement of the second oscillating seat 52 in the width direction of the oscillating disk 4 and the movement of the first oscillating seat 51 in the length direction of the oscillating disk 4 can be achieved simultaneously, so that the oscillating disk 4 presents an oblique oscillation, further improving the oscillation effect.

[0038] In this embodiment, referring again to Figure 2 As shown, the oscillating assembly 5 further includes a transmission disk 56. The transmission disk 56 is carried on the second oscillating seat 52. The oscillating disk 4 is located above the transmission disk 56. Four end portions on the circumferential side of the transmission disk 56 are respectively provided with transmission shafts 57, and the four transmission shafts 57 are respectively connected to the four end portions of the oscillating disk 4 in a corresponding manner.

[0039] An oscillating box 6 for accommodating the oscillating assembly 5 is further provided in the box body 1. Four transmission openings 61 are opened on the upper side wall of the oscillating box 6, and the four transmission shafts 57 are respectively inserted into the four transmission openings 61 in a one-to-one correspondence.

[0040] In this embodiment, referring to Figure 2 and Figure 4 As shown, buffer components 7 are respectively provided on the circumferential side wall of the oscillating box 6. There are multiple buffer components 7 and they are arranged at intervals around the circumference of the oscillating box 6. Each buffer component 7 respectively includes a buffer seat 71, a buffer groove 72 opened on the buffer seat 71, and a ball 73 movably arranged in the buffer groove 72. The notch of the buffer groove 72 faces the transmission disk 56. The diameter of the ball 73 is larger than the notch diameter of the buffer groove 72. The transmission disk 56 can abut against the ball 73 or be separated from the ball 73. During the oscillation of the oscillating disk 4, the ball 73 can achieve buffering for the oscillating disk 4 through its own movement, avoiding the oscillating disk 4 directly hitting the oscillating box 6 and affecting the oscillation process of the oscillating disk 4.

[0041] In this embodiment, referring to Figure 4As shown, the buffer assembly 7 further includes a first buffer channel 74 opened in the buffer seat 71 and communicating with the buffer groove 72, a second buffer channel 75 communicating with the first buffer channel 74, and an elastic member 76 provided at one end of the second buffer channel 75 away from the first buffer channel 74. The first buffer channel 74 is arranged along the horizontal direction, and the second buffer channel 75 is arranged along the vertical direction. A first buffer rod 77 is arranged in the first buffer channel 74. One end of the first buffer rod 77 abuts against the ball 73, and the other end has a first inclined surface 771. A second buffer rod 78 is arranged in the second buffer channel 75. One end of the second buffer rod 78 has a second inclined surface 781 that matches and fits with the first inclined surface 771, and the other end is connected to the elastic member 76. Among them, the elastic member 76 is a spring. When the oscillating disk 4 impacts on the ball 73, it can achieve multiple buffering under the action of the ball 73, the first buffer rod 77, the first inclined surface 771, the second inclined surface 781, the second buffer rod 78 and the elastic member 76, further improving the oscillation stability of the oscillating disk 4.

[0042] Combined again Figure 2 As shown, a guide groove 561 is further annularly provided on the circumferential side of the transmission disk 56. The longitudinal section of the guide groove 561 is trapezoidal in reverse. The ball 73 is arranged to be rollable along the length direction of the guide groove 561, and its opposite side portions abut against the two side groove walls of the guide groove 561. When the oscillating disk 4 abuts against the ball 73, the ball 73 can roll in the trapezoidal in reverse guide groove 561, which can not only further improve the oscillation stability of the oscillating disk 4, but also the ball 73 only has point contact with the two side groove walls of the guide groove 561, reducing the contact area and friction force between the ball 73 and the oscillating disk 4, making the oscillation of the oscillating disk 4 smoother.

[0043] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
