Description

Technical Field

[0001] This application relates to the field of incubator technology, and in particular to a semiconductor-cooled carbon dioxide oscillating incubator. Background Technology

[0002] A carbon dioxide shaking incubator is a culture container used for cell culture, fermentation, hybridization, biochemistry, and cell tissue research. Through the combination of a shaking module and a carbon dioxide module, the incubator can simultaneously provide both a shaking environment and a carbon dioxide environment, making it suitable for cultures that have high requirements for both carbon dioxide and shaking.

[0003] However, in existing CO2 shaking incubators, the shaking disc is driven by a cam. Because the cam's eccentric displacement is small, the shaking amplitude of the disc is also small, which significantly reduces the culture quality and efficiency. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this application provides a semiconductor-cooled carbon dioxide oscillating incubator with a large oscillation amplitude.

[0005] The carbon dioxide shaking incubator provided in this application adopts the following technical solution: A semiconductor-cooled carbon dioxide shaking incubator includes a housing, a semiconductor module and a carbon dioxide module disposed on the housing, and a shaking disk disposed within the housing. The shaking disk is horizontally arranged. The carbon dioxide shaking incubator also includes a shaking assembly disposed within the housing and located below the shaking disk. The shaking assembly includes a first shaking seat movably disposed along the length direction of the shaking disk, a second shaking seat movably disposed on the first shaking seat along the width direction of the shaking disk, a transmission module for moving the first shaking seat and the second shaking seat, and a drive module for driving the transmission module to operate. The shaking disk is supported on the second shaking seat.

[0006] By adopting the above technical solution, the oscillation disk can oscillate back and forth along its own length and width directions with the cooperation of the first oscillation seat and the second oscillation seat, which effectively increases the oscillation amplitude of the oscillation disk and improves the culture quality and culture efficiency.

[0007] Preferably, the length direction of the second oscillating seat is the same as the width direction of the oscillating disk, and the two ends of the length direction of the second oscillating seat are a first end and a second end, respectively. The transmission module includes a first pulley disposed at the first end and a pull rope connected to the first pulley. The rotation axis of the first pulley extends in the vertical direction. The pull rope includes two ropes respectively located on both sides of the first pulley. The two ropes are respectively connected to the two sides of the second end. The driving module includes two second pulleys respectively disposed on both sides of the width direction of the second oscillating seat and two driving members respectively for driving the two second pulleys to rotate. The two second pulleys are respectively connected to the two ropes.

[0008] By adopting the above technical solution, the first and second oscillation seats can move stably with the cooperation of the two second pulleys, the pull rope and the first pulley, which effectively improves the oscillation stability of the oscillation plate and prevents the culture on the oscillation plate from falling off during the oscillation process.

[0009] Preferably, the transmission module further includes two third pulleys disposed on the first oscillating seat and located on both sides of the width direction of the second oscillating seat. The two third pulleys are disposed near the second end, and the two ropes are respectively connected to the two third pulleys for transmission.

[0010] By adopting the above technical solution, the second oscillating seat can move stably along the width direction of the oscillating disk with the cooperation of two second pulleys, a pull rope, and two third pulleys. This not only further improves the oscillation stability of the oscillating disk, but also allows the two third pulleys to correct the direction of the pull rope's movement, preventing the second oscillating seat from shifting during movement.

[0011] Preferably, the transmission module further includes two fourth pulleys disposed on the first oscillating seat and located on both sides of the width direction of the second oscillating seat. The two fourth pulleys are disposed close to the first end, and the two ropes are respectively connected to the two fourth pulleys for transmission.

[0012] By adopting the above technical solution, the first oscillating seat can move stably along the length of the oscillating disk with the cooperation of two second pulleys, a pull rope, and two fourth pulleys. This not only further improves the oscillation stability of the oscillating disk, but also the two fourth pulleys can correct the movement direction of the pull rope, preventing the first oscillating seat from deviating during the movement.

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

[0014] By adopting the above technical solution, the first oscillating seat can be supported on the base, effectively improving the movement stability of the first oscillating seat.

[0015] Preferably, the oscillation assembly further includes a transmission disk, which is supported on the second oscillation base and located above the transmission disk. The peripheral ends of the transmission disk are respectively provided with transmission shafts, and multiple transmission shafts are respectively connected to the peripheral ends of the oscillation disk.

[0016] By adopting the above technical solution, the peripheral ends of the oscillating disk can be connected to the transmission disk through multiple transmission shafts, which not only improves the installation strength of the oscillating disk, but also reduces the transmission loss between the transmission disk and the vibrating disk.

[0017] Preferably, the housing is further provided with an oscillation box for accommodating the oscillation component, and the upper side wall of the oscillation box is provided with multiple transmission ports, and the multiple transmission shafts are respectively inserted into the multiple transmission ports.

[0018] By adopting the above technical solution, the oscillation component can be housed in the oscillation box, preventing the culture on the oscillation plate from falling into the oscillation component and affecting its operation; at the same time, the transmission port can make way for the transmission shaft, avoiding interference between the oscillation box and the transmission between the oscillation component and the oscillation plate.

[0019] Preferably, the oscillation box is provided with buffer components on its peripheral sidewalls. Each buffer component includes a buffer seat, a buffer groove formed on the buffer seat, and a ball that is movably disposed in the buffer groove. The opening of the buffer groove faces the transmission disk. The diameter of the ball is larger than the diameter of the opening of the buffer groove. The transmission disk can abut against the ball or separate from the ball.

[0020] By adopting the above technical solution, the ball bearings can buffer the oscillating disk through their own movement during the oscillation process, thus preventing the oscillating disk from directly impacting the oscillation box and affecting the oscillation process of the oscillating disk.

[0021] Preferably, the buffer assembly further includes a first buffer channel formed within the buffer seat and communicating with the buffer groove, a second buffer channel communicating with the first buffer channel, and an elastic member disposed at one end of the second buffer channel away from the first buffer channel. A first buffer rod is disposed within the first buffer channel, with one end of the first buffer rod abutting against the ball and the other end having a first inclined surface. A second buffer rod is disposed within the second buffer channel, with one end of the second buffer rod having a second inclined surface that matches and fits against the first inclined surface and the other end connected to the elastic member.

[0022] By adopting the above technical solution, the oscillating disk can achieve multiple buffering under the action of the ball, the first buffer rod, the first inclined plane, the second inclined plane, the second buffer rod and the elastic element, which further improves the oscillation stability of the oscillating disk.

[0023] Preferably, the transmission disc has a guide groove circumferentially arranged on its side, the longitudinal section of the guide groove is an inverted trapezoid, the ball is arranged to roll along the length of the guide groove and its opposite sides abut against the side walls of the guide groove.

[0024] By adopting the above technical solution, when the oscillating disk and the ball are in contact, the ball can roll in the inverted trapezoidal guide groove, which can not only further improve the oscillation stability of the oscillating disk, but also reduce the contact area and friction between the ball and the oscillating disk by only contacting the two side walls of the guide groove, making the oscillation of the oscillating disk smoother.

[0025] In summary, the present invention has at least one of the following beneficial technical effects: The oscillating disc can oscillate back and forth along its length and width directions with the cooperation of the first and second oscillating seats, which effectively increases the oscillation amplitude of the oscillating disc and improves the culture quality and culture efficiency.

[0028] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0029] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0030] See Figure 1-4 As shown, a semiconductor-cooled carbon dioxide shaking incubator includes an upright chamber 1, a semiconductor module 2 and a carbon dioxide module 3 mounted on the chamber 1, a stainless steel inner liner 8 inside the chamber 1, two shelves 9 arranged vertically and horizontally within the inner liner 8, and a horizontally positioned shaking plate 4 below the shelves 9. The semiconductor module 2 is located on one side of the chamber 1, and a door 11 is located on the other side of the chamber 1. The direction from the semiconductor module 2 to the door 11 is the width direction of the shaking plate 4, and the direction perpendicular to this width direction is the length direction of the shaking plate 4. Both the width and length directions are horizontal. Semiconductor module 2 is a Peltier thermoelectric semiconductor refrigeration device in the prior art, which can efficiently refrigerate and keep the inner liner 8 at a low temperature, reducing energy consumption by more than 85% compared to compressor refrigeration; carbon dioxide module 3 includes a gas inlet for introducing carbon dioxide and a filter located at the gas inlet, and the gas inlet is connected to the inner liner 8; an air duct 10 is provided on the housing 1, with one end of the air duct 10 connected to semiconductor module 2 and the other end connected to the inner liner 8.

[0031] In this embodiment, combined with Figure 2 As shown, an oscillation assembly 5 is also provided below the oscillation disk 4. The oscillation assembly 5 includes a base 55 arranged along the length direction of the oscillation disk 4, a first oscillation seat 51 movably disposed on the base 55 along the length direction of the oscillation disk 4, a second oscillation seat 52 movably disposed on the first oscillation seat 51 along the width direction of the oscillation disk 4, a transmission module 53 for driving the first oscillation seat 51 and the second oscillation seat 52 to move, and a drive module 54 for driving the transmission module 53 to run. The oscillation disk 4 is supported on the second oscillation seat 52.

[0032] After the culture is placed on the oscillation disk 4, the drive module 54 and the transmission module 53 work together to drive the first oscillation seat 51 and the second oscillation seat 52 to move along the length and width directions of the oscillation disk 4, respectively. This allows the oscillation disk 4 to oscillate back and forth along its own length and width directions with the cooperation of the first oscillation seat 51 and the second oscillation seat 52, effectively increasing the oscillation amplitude of the oscillation disk 4 and improving the culture quality and culture efficiency.

[0033] In this embodiment, combined with Figure 3 As shown, the length direction of the second oscillating base 52 is the same as the width direction of the oscillating disk 4. The two ends of the length direction of the second oscillating base 52 are the first end and the second end, respectively. The transmission module 53 includes a first pulley 531 disposed at the first end, a pull rope 532 connected to the first pulley 531, two third pulleys 533 disposed on the first oscillating base 51 and located on both sides of the width direction of the second oscillating base 52, and two fourth pulleys 534 disposed on the first oscillating base 51 and located on both sides of the width direction of the second oscillating base 52. The drive module 54 includes two second pulleys 541 respectively disposed at both ends of the length direction of the base 55, and two drive members 542 respectively used to drive the two second pulleys 541 to rotate. The drive members 542 are stepper motors.

[0034] The first pulley 531 has its rotation axis extending vertically. Two third pulleys 533 are located near the second end, and two fourth pulleys 534 are located near the first end. The pull rope 532 includes two ropes located on both sides of the first pulley 531. The two ropes are connected to the two sides of the second end. Each rope is wound around the third pulley 533, the second pulley 541, the fourth pulley 534, and the first pulley 531 in sequence 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 move stably under the transmission cooperation of the first pulley 531, the second pulley 541, the third pulley 533, the fourth pulley 534 and the pull rope 532, which effectively improves the oscillation stability of the oscillating disk 4 and prevents the culture on the oscillating disk 4 from falling off during oscillation. In addition, the two third pulleys 533 and the two fourth pulleys 534 are located at the four ends of the first oscillating seat 51, and the two can cooperate with each other to correct the movement direction of the pull rope 532, so as to prevent the first oscillating seat 51 and the second oscillating seat 52 from deviating during 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 periodically rotate forward and reverse to realize the reciprocating oscillation of the oscillating disk 4. Specifically, when it is necessary to control the oscillating disk 4 to oscillate along its width, it is only necessary to make the rotation directions of the two second pulleys 541 opposite. During their respective rotation, the two second pulleys 541 can pull the same end of the second oscillating seat 52 through the two ropes to realize the movement of the second oscillating seat 52. When it is necessary to control the oscillating disk 4 to oscillate along its length, it is only necessary to make the rotation directions of the two second pulleys 541 the same. During their respective rotation, the two second pulleys 541 can pull the different ends of the second oscillating seat 52 through the two ropes to pull the second oscillating seat 52 to move along the length direction of the oscillating disk 4 to realize the movement of the first oscillating seat 51.

[0037] In some other embodiments, one of the two second pulleys 541 can be driven to rotate independently, which can simultaneously realize 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, so that the oscillating disk 4 presents oblique oscillation, further improving the oscillation effect.

[0038] In this embodiment, combined again Figure 2 As shown, the oscillation assembly 5 also includes a transmission disk 56, which is supported on the second oscillation base 52. The oscillation disk 4 is located above the transmission disk 56. The four ends of the transmission disk 56 are respectively provided with transmission shafts 57, and the four transmission shafts 57 are respectively connected to the four ends of the oscillation disk 4.

[0039] Inside the housing 1, there is also an oscillation box 6 for housing the oscillation assembly 5. The upper side wall of the oscillation box 6 has four transmission ports 61, and four transmission shafts 57 are inserted into the four transmission ports 61 in a corresponding manner.

[0040] In this embodiment, combined with Figure 2 and Figure 4 As shown, buffer components 7 are respectively provided on the peripheral sidewalls of the oscillation box 6. Multiple buffer components 7 are arranged at intervals around the circumference of the oscillation box 6. Each buffer component 7 includes a buffer seat 71, a buffer groove 72 formed on the buffer seat 71, and a movable ball 73 disposed within the buffer groove 72. The opening of the buffer groove 72 faces the transmission disk 56, and the diameter of the ball 73 is larger than the diameter of the opening of the buffer groove 72. The transmission disk 56 can abut against the ball 73 or separate from the ball 73. During the oscillation of the oscillation disk 4, the ball 73 can buffer the oscillation disk 4 through its own movement, preventing the oscillation disk 4 from directly impacting the oscillation box 6 and affecting the oscillation process of the oscillation disk 4.

[0041] In this embodiment, combined with Figure 4As shown, the buffer assembly 7 also includes a first buffer channel 74 formed within 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 element 76 disposed at the end of the second buffer channel 75 away from the first buffer channel 74. The first buffer channel 74 is arranged horizontally, and the second buffer channel 75 is arranged vertically. A first buffer rod 77 is disposed within the first buffer channel 74, one end of which abuts against the ball 73, and the other end has a first inclined surface 771. A second buffer rod 78 is disposed within the second buffer channel 75, one end of which has a second inclined surface 781 that matches and fits against the first inclined surface 771, and the other end is connected to the elastic element 76. The elastic element 76 is a spring. When the oscillating disk 4 impacts 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 element 76, further improving the oscillation stability of the oscillating disk 4.

[0042] Recombined Figure 2 As shown, a guide groove 561 is also provided around the periphery of the transmission disk 56. The longitudinal section of the guide groove 561 is an inverted trapezoid. The ball 73 is arranged to roll along the length of the guide groove 561, and its opposite sides abut against the side walls of the guide groove 561. When the oscillating disk 4 abuts against the ball 73, the ball 73 can roll within the inverted trapezoidal guide groove 561, which not only further improves the oscillation stability of the oscillating disk 4, but also reduces the contact area and friction between the ball 73 and the oscillating disk 4 by only making point contact with the side walls of the guide groove 561, thus making the oscillation of the oscillating disk 4 smoother.

[0043] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
