DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-9 The present invention is described in further detail.

[0021] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0022] See also Figure 1-9 As shown, a semiconductor refrigeration low-temperature oscillating incubator is shown, including a box body 1, the box body 1 includes a shell 1a, a box door 1d that can be opened and closed and arranged on the shell 1a, and a stainless steel inner liner 1b suspended in the shell 1a, a semiconductor module 2 is arranged on the shell 1a, and the semiconductor module 2 and the box door 1d are respectively located on both sides of the width direction of the shell 1a, and two horizontal shelves 18 and an oscillation module 3 and a first driving component 4 for driving the oscillation module 3 to oscillate are arranged in sequence in the vertical direction in the inner liner 1b, and a purple light 19 is also arranged on the top of the inner liner 1b, wherein the semiconductor module 2 is a Peltier thermoelectric semiconductor refrigeration device in the prior art, which can efficiently refrigerate and keep a low-temperature environment in the inner liner 1b, and the energy consumption is reduced by more than 85% compared with the compressor refrigeration. The side of the shell 1a is also provided with an air duct 20, one end of the air duct 20 is connected to the semiconductor module 2, and the other end is connected to the inner liner 1b.

[0023] In this embodiment, combined with Figure 3and Figure 5 As shown, the oscillation module 3 includes a horizontally arranged oscillation plate 3a and a sewage plate 3b arranged below the oscillation plate 3a. A plurality of through holes 3c are spaced apart on the oscillation plate 3a. One end of the sewage plate 3b is connected to the oscillation plate 3a, and the other end is inclined downward along the length direction of the oscillation plate 3a. A first sewage outlet 3d is formed between the end of the sewage plate 3b in the inclined direction and the oscillation plate 3a. A sewage tank 5 is provided at the bottom of the inner tank 1b around the circumferential ring of the oscillation module 3, and the first sewage outlet 3d is arranged toward the sewage tank 5.

[0024] After the culture is placed on the oscillation plate 3a, the culture can be oscillated under the oscillation action of the oscillation plate 3a, and the culture medium that falls outward during the oscillation process can fall downward from the through hole 3c under the action of the oscillation, and then discharged into the sewage tank 5 through the cooperation of the sewage plate 3b and the first sewage outlet 3d, which effectively avoids the residue of the culture medium on the oscillation plate 3a, not only can avoid the growth of bacteria, but also will not affect the subsequent placement of the culture on the oscillation plate 3a.

[0025] Specifically, after the culture medium falls onto the oscillating plate 3a, most of the culture medium can fall onto the drain plate 3b through the through hole 3c and move along the inclined surface of the drain plate 3b toward the first drain port 3d, and then enter the sewage tank 5 through the first drain port 3d. In this way, the operator only needs to regularly clean a small amount of residue between adjacent through holes 3c, and this small amount of residue will not affect the cultivation of the culture by the oscillating plate 3a.

[0026] In this embodiment, the oscillating plate 3a is rectangular, and three side plates 3e are arranged around its circumferential side, and the three side plates 3e are connected to the circumferential side of the drainage plate 3b, and the oscillating plate 3a, the three side plates 3e and the drainage plate 3b form a drainage cavity 3f, and the first drainage port 3d is connected to the drainage cavity 3f. The culture medium dropped from the through hole 3c to the drainage plate 3b can be restricted in the drainage cavity 3f by the multiple side plates 3e, which effectively prevents the culture medium from falling outward and causing contamination to other components in the inner tank 1b.

[0027] In this embodiment, the low-temperature oscillating incubator further includes a dirt-pushing plate 6 disposed in the dirt-discharging cavity 3f and movable along the inclination direction of the dirt-discharging tray 3b, and a second driving assembly 7 for driving the dirt-pushing plate 6 to move. The dirt-pushing plate 6 extends along the width direction of the oscillating tray 3a and its bottom is disposed close to the dirt-discharging tray 3b. After the culture medium falls on the dirt-discharging tray 3b, the dirt-pushing plate 6 can push the culture medium on the dirt-discharging tray 3b toward the first dirt-discharging port 3d under the drive of the second driving assembly 7, which can not only improve the dirt-discharging efficiency, but also prevent the culture medium from remaining on the dirt-discharging tray 3b and blocking the subsequent culture medium.

[0028] Among them, combined Figure 6As shown, the three side plates 3e include two first side plates 3e1 located on both sides of the oscillation plate 3a in the width direction, and a second side plate 3e2 located on the opposite side of the first sewage outlet 3d. The inner side of each first side plate 3e1 is respectively provided with a first slide groove 8, and the first slide groove 8 extends along the inclined direction of the sewage discharge plate 3b. Transmission rods 9 are respectively provided at both ends of the sewage pushing plate 6. The two transmission rods 9 are respectively slidably connected to the two first slide grooves 8. The second driving assembly 7 has two driving parts 7c, and the two driving parts 7c are respectively connected to the two transmission rods 9.

[0029] In this embodiment, combined with Figure 3 , Figure 5 and Figure 7 As shown, the second driving assembly 7 includes two driving units respectively arranged on both sides of the width direction of the oscillation disk 3a, each driving unit includes a first driving seat 7a, a second slide groove 7b opened on the first driving seat 7a and extending along the length direction of the oscillation disk 3a, and the above-mentioned driving part 7c, the driving part 7c includes a slider 7c1 slidable in the extension direction of the second slide groove 7b and arranged in the second slide groove 7b, a first power module 7c2 for driving the slider 7c1 to slide, the first power module 7c2 is a cylinder, a connecting rod 7c3 is hinged on the slider 7c1, and the connecting rod 7c3 is L-shaped, and the two sides of the oscillation disk 3a in the width direction are respectively provided with connecting grooves 10 extending along the length direction of the second slide groove 7b, and the other end of the connecting rod 7c3 is penetrated into the connecting groove 10 and connected to the corresponding transmission rod 9.

[0030] When the first power module 7c2 drives the slider 7c1 to reciprocate, the dirt-pushing plate 6 moves synchronously with the slider 7c1 driven by the connecting rod 7c3. Since the connecting rod 7c3 and the slider 7c1 are hinged, the slider 7c1 moving in the horizontal direction can drive the dirt-pushing plate 6 to move in the inclined direction, effectively avoiding interference between the driving stroke of the slider 7c1 and the moving stroke of the dirt-pushing plate 6.

[0031] In this embodiment, the first slide groove 8 is annular, and includes a first groove body 8a and a second groove body 8b arranged up and down and connected to each other. The first groove body 8a and the second groove body 8b are parallel to each other and extend along the inclined direction of the sewage discharge plate 3b respectively. An arc-shaped transition groove 8c is connected between the two ends of the first groove body 8a and the second groove body 8b respectively, and the transmission rod 9 can reciprocate between the first groove body 8a, the second groove body 8b and the two transition grooves 8c.

[0032] Specific, combined Figure 3As shown, when the transmission rod 9 is in the second slot body 8b, the dirt pushing plate 6 conflicts with the drain pan 3b. At this time, the cylinder is in the extension stroke. The dirt pushing plate 6 pushes the culture medium on the drain pan 3b during the movement toward the first drain port 3d. When the transmission rod 9 reaches the end of the second slot body 8b, it can reach the first slot body 8a through the arc surface of one of the transition slots 8c. Figure 5 As shown, when the transmission rod 9 is located in the first trough body 8a, the sewage pushing plate 6 is separated from the sewage discharge plate 3b. At this time, the cylinder is in a contraction stroke. The sewage pushing plate 6 is separated from the sewage discharge plate 3b during the movement away from the first sewage discharge port 3d. It will not interfere with the culture medium moving along the inclined surface of the sewage discharge plate 3b. When the transmission rod 9 reaches the end of the first trough body 8a, it can reach the second trough body 8b through the arc surface of another transition groove 8c.

[0033] In this embodiment, combined with Figure 6-7 As shown, the sewage tank 5 includes a third tank body 5a and a fourth tank body 5b located at both ends of the length direction of the oscillation plate 3a, and two fifth tank bodies 5c located on both sides of the width direction of the oscillation plate 3a. A second sewage outlet 11 is provided at one end of the third tank body 5a away from the box door 1d, and the third tank body 5a is arranged to be inclined downward from the direction from the box door 1d to the second sewage outlet 11. The two fifth tank bodies 5c are arranged to be inclined downward from the direction from the fourth tank body 5b to the third tank body 5a, and the fourth tank body 5b and the third tank body 5a are parallel to each other.

[0034] During the oscillation of the oscillating disk 3a, part of the culture medium thereon will directly fall into the sewage tank 5 on the surrounding side. By setting the inclined fourth tank body 5b and the fifth tank body 5c, the culture medium in the sewage tank 5 can be collected in the third tank body 5a and fall into the second sewage outlet 11 along the inclined direction of the third tank body 5a, which can not only further improve the sewage discharge efficiency, but also prevent the culture medium from remaining in the sewage tank 5 and blocking the subsequent discharge of the culture medium.

[0035] In this embodiment, combined with Figure 3 and Figure 5 As shown, a shock block 12 movable along the horizontal direction and a third driving component 13 for driving the shock block 12 to move are provided in the outer shell 1a. The third driving component 13 is a cylinder arranged on the inner wall of the outer shell 1a. The end of the shock block 12 has a mating surface matching the third groove body 5a. The shock block 12 can hit the third groove body 5a and close the second sewage outlet 11 during its movement, or be separated from the second sewage outlet 11.

[0036] In this way, the culture medium collected in the third trough 5a can fall toward the second sewage outlet 11 more smoothly under the impact of the shock block 12, avoiding the culture medium remaining in the third trough 5a due to the friction force; at the same time, the culture medium falling into the second sewage outlet 11 can be quickly discharged when the shock block 12 is separated from the second sewage outlet 11, which greatly improves the sewage discharge efficiency.

[0037] In this embodiment, combined with Fig. 9 As shown, a compartment 1c is formed between the inner tank 1b and the outer shell 1a, and a third chute 14 and a dirt hopper 15 are provided at the bottom of the compartment 1c near the third tank body 5a. The third chute 14 extends along the width direction of the oscillating plate 3a, and a roller 16 is provided at the bottom of the dirt hopper 15. The roller 16 is rollably arranged in the third chute 14. A positioning groove 17 is provided at one end of the third chute 14 away from the box door 1d. When the roller 16 is accommodated in the positioning groove 17, the dirt hopper 15 is located directly below the second sewage outlet 11. After the operator opens the box door 1d, the dirt hopper 15 can be conveniently taken and placed through the cooperation of the third chute 14. At the same time, when placing the dirt hopper 15, it only needs to be directly pushed inward, and the positioning groove 17 can position the dirt hopper 15 to prevent the dirt hopper 15 from deviating relative to the second sewage outlet 11 and affecting its collection of culture medium.

[0038] In this embodiment, again combined Figure 3 and Figure 5 As shown, the first driving assembly 4 includes a second driving seat 4a, three eccentric wheels 4b arranged on the second driving seat 4a, a second power module 4c for driving one of the eccentric wheels 4b to rotate, and a driving plate 4d. Among them, the second driving seat 4a is supported on the bottom of the inner tank 1b, the rotation axes of the three eccentric wheels 4b extend along the vertical direction respectively, the second power module 4c is a motor, the motor is connected to one of the eccentric wheels 4b through a belt drive, the eccentric ends of the three eccentric wheels 4b are connected to the driving plate 4d respectively, the oscillating disk 3a includes a disk body 3a1, a horizontal transmission plate 3a2 arranged at the lower part of the disk body 3a1, a through hole 3c is opened on the disk body 3a1, and the peripheral end of the driving plate 4d corresponds to the peripheral end of the transmission plate 3a2 one by one and is connected to each other through four pins.
