Description

Technical Field

[0001] The present invention relates to the technical field of incubators, and in particular to an oscillation drive mechanism installation structure and an oscillation incubator. Background Art

[0002] The oscillating incubator is a laboratory biological sample culture equipment, mainly used for constant temperature oscillation culture of biological samples such as cells and microorganisms.

[0003] The oscillating incubator in the prior art includes a culture chamber, and a sinking motor chamber 8 is provided at the bottom of the culture chamber. The sinking motor chamber 8 is located in a downward groove space at the bottom of the culture chamber and is connected to the culture chamber. A motor and a transmission mechanism are installed in the sinking motor chamber. The motor drives the tray (or clamp plate) to shake in a horizontal plane, thereby oscillating the culture bottles on the tray (or clamp plate).

[0004] The applicant has found that the prior art has at least the following technical problems: 1. The sinking motor bin 8 is located in the groove space at the bottom of the culture bin and is connected to the culture bin. The temperature and humidity environment in the culture bin is complex, and the experimental samples often tip over or fall due to improper operation, which can easily cause pollutants to accumulate at the bottom of the culture bin and in the motor bin, resulting in the problem that the motor bin is easy to hide dirt and is difficult to clean; 2. The transmission belt of the motor is also in the motor bin. The belt is prone to aging and dust caused by long-term operation, which causes suspended particle pollution in the culture bin; 3. The motor is in the sinking motor bin 8, which is located in the groove space at the bottom of the culture bin and is connected to the culture bin, resulting in the culture bin being set at a high temperature of 160℃~180℃ for sterilization, which will cause damage to the motor, so that it is impossible to achieve high-temperature sterilization at 160℃~180℃. 4.

[0032] See also Figure 6 The oscillating incubator in the prior art includes a culture chamber, and a sinking motor chamber 8 is provided at the bottom of the culture chamber. The sinking motor chamber 8 is located inside the culture chamber and is connected to the culture chamber. A motor and a transmission mechanism are installed in the sinking motor chamber. The motor drives the tray (or fixture plate) to shake in a horizontal plane, thereby oscillating the culture bottles on the tray (or fixture plate). The sinking motor chamber 8 is at the bottom of the culture chamber, which is not easy to clean and is easy to hide dirt and contaminate the sample; and the sinking motor chamber 8 is located in the culture chamber, which is not conducive to the heat dissipation of the motor when the culture chamber is heated, thereby reducing the service life of the motor.

[0033] In view of the above problems, an embodiment of the present invention provides an oscillation drive mechanism installation structure to prevent dust and bacteria from accumulating at the bottom of the culture chamber, facilitate heat dissipation of the drive device, and increase the service life.

[0034] Combine the following Figure 1-Figure 5 The technical solution provided by the present invention is described in more detail.

[0035] Embodiment 1:

[0036] like Figure 1-Figure 4As shown, the oscillation drive mechanism installation structure provided by the present invention includes a motor compartment 100 located in the box body 1, the motor compartment 100 is isolated from the outside of the culture compartment 300, and the motor compartment 100 is located on the side of the culture compartment 300; a rocker shaft portion 6 is provided at the bottom of the culture compartment 300, and the rocker shaft portion 6 is sealed and passes through the bottom wall of the culture compartment 300 and is rotatably arranged; the driving mechanism includes a driving device 2 and a transmission assembly, the driving device 2 is fixed in the motor compartment 100, the transmission assembly is located outside the culture compartment 300, the driving device 2 is connected to the transmission assembly, and the transmission assembly is connected to the rocker shaft portion 6, and is used to drive the rocker shaft portion 6 to rotate under the drive of the driving device 2.

[0037] See also Figure 1 and Figure 2 As shown, in order to clearly see the structure of the motor compartment 100, a portion of the side wall of the box body 1 is omitted in the figure. The motor compartment 100 is formed on the side of the culture compartment 300 and is not connected to the culture compartment 300, which is convenient for heat dissipation of the drive device 2 and prevents the temperature of the drive device 2 from being too high when high-temperature sterilization is performed in the culture compartment 300.

[0038] The driving device 2 can be a motor in the prior art, and the motor is fixed in the motor compartment 100 through a mounting frame.

[0039] The rocking shaft portion 6 is provided with a tray 7, and the tray 7 is located in the culture chamber 300. Figure 5 When the rocking shaft portion 6 rotates with its own axis as the axis center, it can drive the tray 7 to rock in the horizontal plane, thereby oscillating the culture bottle on the tray 7.

[0040] The oscillation drive mechanism installation structure of this embodiment is configured with a motor compartment 100 in the housing 1. The motor compartment 100 is located at the side of the culture compartment 300 and isolated from the culture compartment 300. The drive device 2 is fixed in the motor compartment 100 and is laterally disposed relative to the rocking shaft portion 6. The drive device 2 drives the rocking shaft portion 6 to rotate through the transmission assembly, thereby providing an oscillating driving force.

[0041] The oscillation drive mechanism installation structure does not set a sinking motor bin in the culture bin 300, which prevents dust and bacteria from accumulating at the bottom of the culture bin 300 and facilitates comprehensive cleaning and high-temperature sterilization of the culture bin 300; and the drive device 2 is not in the culture bin 300, which facilitates heat dissipation of the drive device 2 and improves its service life.

[0042] As an alternative embodiment, see Figure 4 As shown, the oscillation drive mechanism installation structure of this embodiment also includes a bottom bin 200 , which is isolated from the culture bin 300 , is located at the bottom of the culture bin 300 , and at least part of the transmission assembly is located inside the bottom bin 200 .

[0043] The bottom bin 200 is surrounded by a partition, and the bottom bin 200 is not connected to the culture bin 300. The transmission assembly is located in the bottom bin 200 to prevent dirt from being stored in the culture bin 300.

[0044] As an alternative embodiment, see Figure 3 and Figure 4 As shown, the transmission assembly includes a driven wheel 3, and a driving wheel 21 is provided at the output end of the driving device 2, wherein: the driving wheel 21 is located in the motor bin 100, the driven wheel 3 is located in the bottom bin 200, and the driven wheel 3 is fixedly connected to the rocker shaft part 6, and the driving wheel 21 and the driven wheel 3 are connected through a belt 4 or a chain transmission.

[0045] In this embodiment, the driving wheel 21 is connected to the driven wheel 3 through a belt 4 to reduce transmission noise. The transmission assembly has a simple structure and is completely isolated from the culture chamber 300. The driving device 2 drives the driven wheel 3 and the rocking shaft 6 to rotate, thereby driving the tray 7 to shake in the horizontal plane, thereby oscillating the culture bottles in the tray 7.

[0046] As an alternative embodiment, see Figure 4 As shown, the outer diameter of the driven wheel 3 is greater than the outer diameter of the driving wheel 21 , and the rocker shaft portion 6 is fixed to the inner ring of the driven wheel 3 .

[0047] With such arrangement, the power of the driving device 2 is transmitted to the driven wheel 3 after being decelerated, thereby driving the swing shaft portion 6 to rotate.

[0048] As an alternative embodiment, see Figure 4 As shown, a through opening 5 is provided on the side wall of the bottom bin 200 facing the motor bin 100 , and a belt 4 or a chain passes through the through opening 5 , and drives and connects the driving wheel 21 and the driven wheel 3 .

[0049] In the above structure, the bottom compartment 200 and the motor compartment 100 are connected by the through opening 5, and the belt 4 or the chain can pass through the through opening 5 to drive and connect the driving wheel 21 and the driven wheel 3, so as to transmit the power of the driving device 2 to the rocker shaft part 6.

[0050] As an optional embodiment, the number of the rocker shaft portion 6 is one or more than two; see Figure 3 and Figure 4 As shown, when the number of the rocker parts 6 is more than two, all the rocker parts 6 are arranged at intervals on the bottom wall of the culture chamber 300 and support the same tray 7 , and the transmission assembly is only fixedly connected to one of the rocker parts 6 .

[0051] In this embodiment, a plurality of rocker shaft parts 6 are provided (four rocker shaft parts 6 are shown in the figure), and only one of the rocker shaft parts 6 is connected to the transmission assembly, that is, only one rocker shaft part 6 can actively rotate, and the remaining rocker shaft parts 6 play a supporting role and rotate passively driven by the tray 7.

[0052] The above structure can simplify the structure of the oscillation drive mechanism, eliminating the need for redundant drive devices 2 and complex transmission components, and the multiple rocker shafts 6 can stably support the tray 7, thereby improving the stability of the structure.

[0053] As an optional implementation, a heating unit is provided in the bottom bin 200 of this embodiment. The heating unit may be a heating wire or a heating rod.

[0054] Since the bottom of the culture chamber 300 does not have a sinking motor chamber, the driving device 2 is placed sideways, and the bottom of the culture chamber 300 is flat, a heating unit can be provided in the bottom chamber 200 to heat the bottom of the culture chamber 300 .

[0055] As an optional implementation, in this embodiment, heating parts are provided on the six side walls of the culture chamber 300, so that the culture chamber 300 is heated on six sides.

[0056] The oscillation drive mechanism installation structure of this embodiment solves four major problems. Solution to problem 1: In the prior art, the sinking motor bin is located in the groove space downward at the bottom of the culture bin 300 and is connected to the culture bin 300. The temperature and humidity environment in the culture bin is complex, and the experimental samples are often tipped over or dropped due to improper operation, which easily causes pollutants to accumulate at the bottom of the culture bin and in the motor bin, thereby causing the motor bin to easily hide dirt and is not easy to clean, resulting in the problem of pollution of the culture environment; Solution to problem 2: The transmission belt of the motor is also in the motor bin, and the belt is prone to aging after long-term operation to produce dust that causes suspended particle pollution in the culture bin; Solution to problem 3: The motor is in the sinking motor bin, and the sinking motor bin is located in the groove space downward at the bottom of the culture bin and is connected to the culture bin, resulting in the culture bin being set at a high temperature of 160°C to 180°C for sterilization, which will cause damage to the motor, so that high-temperature sterilization at 160°C to 180°C cannot be achieved; Solution to problem 4: The sinking motor bin is located in the culture bin, and when the culture bin is heated, it is not conducive to the heat dissipation of the motor. When the high-humidity environment is turned on for cultivation, the motor part is also exposed to this environment for a long time, and the high temperature and high humidity environment are easy to reduce the service life of the motor.

[0057] The oscillation drive mechanism installation structure of this embodiment has the following beneficial effects:

[0058] 1. The driving device 2 is placed sideways. The driving device 2 is located outside the culture chamber 300 and is not directly subjected to the high temperature in the culture chamber 300. The culture chamber 300 can reach a higher dry heat sterilization temperature, which can reach up to 180°C.

[0059] 2. The whole machine has a long service life and high reliability, which is beneficial to the heat dissipation of the driving device 2 and can extend the service life of the driving device 2.

[0060] 3. The six sides of the culture chamber 300 are heated, so that each position of the inner wall of the culture chamber 300 can be heated to 180 degrees. Compared with the circulating heating, the high temperature heating of the inner wall of the culture chamber 300 is more uniform and comprehensive, without dead corners.

[0061] 4. The drive device 2 is placed sideways, freeing up the inner bottom space of the culture chamber 300 for installing the motor. The bottom surface of the culture chamber 300 is flat and has no dead corners, which increases the area for arranging the high-temperature heating wires and obtains an easy-to-clean surface to prevent bacteria accumulation.

[0063] This embodiment provides an oscillating incubator, comprising a box body 1 and an oscillating drive mechanism, wherein the oscillating drive mechanism is assembled in the box body 1 through the oscillating drive mechanism mounting structure.

[0064] The oscillating incubator of this embodiment can extend its service life, facilitate heat dissipation of the driving device 2, and facilitate high-temperature sterilization.
