Abstract
Description
Technical Field
[0001] This utility model relates to the field of incubator technology, and in particular to an installation structure for an oscillation drive mechanism and an oscillation incubator. Background Technology
[0002] A shaking incubator is a laboratory biological sample culture device, mainly used for the constant temperature shaking culture of biological samples such as cells and microorganisms.
[0003] The existing shaking incubator 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 the horizontal plane, thereby shaking the culture bottles on the tray (or clamp plate).
[0004] The applicant has discovered at least the following technical problems with the existing technology: 1. The recessed motor chamber 8 is located in the downward-facing groove at the bottom of the culture chamber and is connected to the culture chamber. The complex temperature and humidity environment inside the culture chamber, and the frequent tipping or dropping of experimental samples due to improper handling, easily cause contaminants to accumulate at the bottom of the culture chamber and inside the motor chamber, resulting in the motor chamber being prone to accumulating dirt and grime and difficult to clean. 2. The motor's drive belt is also inside the motor chamber. Prolonged operation of the belt can easily lead to aging and the generation of dust, causing suspended particulate pollution in the culture chamber. 3. The motor is located inside the recessed motor chamber 8, which is in the downward-facing groove at the bottom of the culture chamber and is connected to the culture chamber. This means that setting the culture chamber to a high temperature of 160℃~180℃ for sterilization would damage the motor, making it impossible to achieve high-temperature sterilization of 160℃~180℃. 4. The recessed motor chamber 8, located inside the culture chamber, hinders heat dissipation from the motor when the culture chamber is heated. Furthermore, when the culture chamber is in a high-humidity environment, the motor is exposed to this high-humidity environment for extended periods, which reduces the motor's lifespan. Utility Model Content
[0005] The purpose of this invention is to provide an installation structure for an oscillation drive mechanism and an oscillation incubator, to solve the technical problems in the prior art where the sunken motor chamber is located in the incubation chamber, which is not conducive to motor heat dissipation and easily accumulates dust and bacteria. The various technical effects of the preferred technical solutions provided by this invention are detailed below.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] The oscillation drive mechanism installation structure provided by this utility model includes a motor compartment located inside the housing, the motor compartment being isolated from the culture chamber and located on the side of the culture chamber;
[0008] The bottom of the culture chamber is provided with a rocker shaft, which is sealed and passes through the bottom wall of the culture chamber and is rotatable.
[0009] The driving mechanism includes a driving device and a transmission assembly. The driving device is fixed inside the motor chamber, and the transmission assembly is located outside the culture chamber. The driving device is driven to the transmission assembly, and the transmission assembly is connected to the rocker shaft, which is used to drive the rocker shaft to rotate under the drive of the driving device.
[0010] Preferably, the installation structure further includes a base compartment, which is isolated from the culture chamber and located at the bottom of the culture chamber, with at least a portion of the transmission assembly located inside the base compartment.
[0011] Preferably, the transmission assembly includes a driven wheel, and the output end of the drive device is provided with a drive wheel, wherein:
[0012] The drive wheel is located inside the motor compartment, the driven wheel is located inside the bottom compartment, and the driven wheel is fixedly connected to the rocker shaft. The drive wheel and the driven wheel are connected by a belt or chain drive.
[0013] Preferably, the outer diameter of the driven wheel is larger than the outer diameter of the driving wheel, and the rocker shaft is fixed to the inner ring of the driven wheel.
[0014] Preferably, the bottom compartment has an opening on its side wall facing the motor compartment, through which the belt or chain passes and drives the drive wheel and the driven wheel.
[0015] Preferably, a tray is provided on the rocker shaft, and the tray is located inside the culture chamber.
[0016] Preferably, the number of the rocker shafts is one or more;
[0017] When there are two or more rocker shafts, all the rocker shafts are arranged at intervals on the bottom wall of the culture chamber and support the same tray, and the transmission assembly is fixedly connected to only one of the rocker shafts.
[0018] Preferably, a heating element is provided inside the bottom compartment.
[0019] Preferably, heating elements are provided on all six side walls of the culture chamber, thereby providing six-sided heating for the culture chamber.
[0020] This utility model also provides a shaking incubator, including a chamber and a shaking drive mechanism, wherein the shaking drive mechanism is assembled into the chamber via the above-mentioned shaking drive mechanism mounting structure.
[0021] The oscillation drive mechanism mounting structure and oscillation incubator provided by this utility model have the following advantages compared with the prior art: A motor compartment is set inside the incubator, located on the side of the incubator and isolated from it. The drive device is fixed inside the motor compartment. Compared to a side-mounted rocker shaft, the drive device drives the rocker shaft to rotate through a transmission assembly, thereby providing the driving force for oscillation. This oscillation drive mechanism mounting structure eliminates the need for a sunken motor compartment inside the incubator, preventing the accumulation of dirt and grime in the lower motor compartment that is difficult to clean and could contaminate the culture environment. It also prevents dust and bacteria from accumulating at the bottom of the incubator, facilitating thorough cleaning and high-temperature sterilization. Furthermore, since the drive device is not inside the incubator, it facilitates heat dissipation and improves the motor's lifespan. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0032] See Figure 6 Existing shaking incubators include a culture chamber with a recessed motor chamber 8 located at the bottom and connected to it. The recessed motor chamber 8 houses a motor and transmission mechanism. The motor drives a tray (or clamping plate) to shake horizontally, thereby shaking the culture flasks on the tray (or clamping plate). However, the recessed motor chamber 8, being at the bottom of the culture chamber, is difficult to clean and easily accumulates dirt and grime, contaminating the samples. Furthermore, its location within the culture chamber hinders heat dissipation for the motor when the chamber is heated, reducing its lifespan.
[0033] To address the aforementioned issues, this utility model provides an installation structure for an oscillation drive mechanism, which prevents dust and bacteria from accumulating at the bottom of the culture chamber, facilitates heat dissipation from the drive device, and improves its service life.
[0034] The following is combined Figures 1-5 The technical solution provided by this utility model will be described in more detail.
[0035] Example 1:
[0036] like Figures 1-4As shown, the oscillation drive mechanism installation structure provided by this utility model includes a motor compartment 100 located inside the housing 1. The motor compartment 100 is isolated from the culture chamber 300 and is located on the side of the culture chamber 300. A rocker shaft 6 is provided at the bottom of the culture chamber 300. The rocker shaft 6 is sealed and passes through the bottom wall of the culture chamber 300 and is rotatable. The drive mechanism includes a drive device 2 and a transmission assembly. The drive device 2 is fixed inside the motor compartment 100, and the transmission assembly is located outside the culture chamber 300. The drive device 2 is driven and connected to the transmission assembly. The transmission assembly is connected to the rocker shaft 6 and is used to drive the rocker shaft 6 to rotate under the drive of the drive device 2.
[0037] See Figure 1 and Figure 2 As shown, in order to see the structure of the motor compartment 100 clearly, part of the side wall of the box 1 is omitted in the figure. The motor compartment 100 is formed on the side of the culture chamber 300 and is not connected to the culture chamber 300, which facilitates the heat dissipation of the drive device 2 and prevents the drive device 2 from getting too hot when the culture chamber 300 is sterilized at high temperature.
[0038] The drive unit 2 can be a motor as in the prior art, and the motor is fixed in the motor compartment 100 by a mounting bracket.
[0039] The rocker shaft 6 is equipped with a tray 7, which is located inside the culture chamber 300. (See tray 7 for details.) Figure 5 When the rocker shaft 6 rotates around its own axis, it can drive the tray 7 to rock in the horizontal plane, thereby agitating the culture bottles on the tray 7.
[0040] In this embodiment, the oscillation drive mechanism mounting structure has a motor compartment 100 inside the housing 1. The motor compartment 100 is located on the side of the culture chamber 300 and is isolated from the culture chamber 300. The drive device 2 is fixed inside the motor compartment 100. Compared with the rocker shaft 6 being placed on the side, the drive device 2 drives the rocker shaft 6 to rotate through the transmission assembly, thereby providing the driving force for oscillation.
[0041] The installation structure of this oscillation drive mechanism does not include a sunken motor compartment inside the culture chamber 300, preventing dust and bacteria from accumulating at the bottom of the culture chamber 300 and facilitating thorough cleaning and high-temperature sterilization of the culture chamber 300. Furthermore, the drive device 2 is not located inside the culture chamber 300, which facilitates heat dissipation for the drive device 2 and improves its service life.
[0042] As an alternative implementation, see [link to implementation details]. Figure 4 As shown, the oscillation drive mechanism mounting structure of this embodiment also includes a bottom chamber 200, which is isolated from the culture chamber 300. The bottom chamber 200 is located at the bottom of the culture chamber 300, and at least part of the transmission component is located inside the bottom chamber 200.
[0043] The bottom chamber 200 is enclosed by partitions and is not electrically connected to the culture chamber 300. The transmission components are located inside the bottom chamber 200 to prevent dirt and grime from accumulating inside the culture chamber 300.
[0044] As an alternative implementation, see [link to implementation details]. Figure 3 and Figure 4 As shown, the transmission assembly includes a driven wheel 3 and a drive wheel 21 is provided at the output end of the drive device 2. The drive wheel 21 is located in the motor compartment 100, the driven wheel 3 is located in the bottom compartment 200, and the driven wheel 3 is fixedly connected to the rocker shaft 6. The drive wheel 21 and the driven wheel 3 are connected by a belt 4 or a chain.
[0045] In this embodiment, the drive wheel 21 and the driven wheel 3 are connected by a belt 4 to reduce transmission noise. This transmission assembly has a simple structure and is completely isolated from the culture chamber 300. The drive device 2 drives the driven wheel 3 and the rocker shaft 6 to rotate, thereby driving the tray 7 to sway in the horizontal plane, and thus agitating the culture bottles in the tray 7.
[0046] As an alternative implementation, see [link to implementation details]. Figure 4 As shown, the outer diameter of the driven wheel 3 is larger than the outer diameter of the driving wheel 21, and the rocker shaft 6 is fixed to the inner ring of the driven wheel 3.
[0047] With this configuration, the power of the drive unit 2 is reduced in speed and then transmitted to the driven wheel 3, thereby driving the rocker shaft 6 to rotate.
[0048] As an alternative implementation, see [link to implementation details]. Figure 4 As shown, a passage 5 is provided on the side wall of the bottom compartment 200 facing the motor compartment 100. The belt 4 or chain passes through the passage 5 and drives the drive wheel 21 and the driven wheel 3.
[0049] In the above structure, the bottom compartment 200 and the motor compartment 100 are connected by a through-hole 5. The belt 4 or chain can pass through the through-hole 5 to drive the drive wheel 21 and the driven wheel 3, and can transmit the power of the drive device 2 to the rocker shaft 6.
[0050] As an optional implementation, the number of rocker sections 6 is one or more; see also Figure 3 and Figure 4 As shown, when there are two or more rocker shafts 6, all rocker shafts 6 are arranged at intervals on the bottom wall of the culture chamber 300 and support the same tray 7. The transmission component is fixedly connected to only one of the rocker shafts 6.
[0051] In this embodiment, multiple rocker shafts 6 are provided (four rocker shafts 6 are shown in the figure), and only one rocker shaft 6 is connected to the transmission component. That is, only one rocker shaft 6 can rotate actively, while the other rocker shafts 6 play a supporting role and rotate passively under the drive of the tray 7.
[0052] The above structure simplifies the structure of the oscillation drive mechanism, eliminating the need for an extra drive device 2 and complex transmission components. Furthermore, the multiple rocker shafts 6 can stably support the tray 7, thus improving the stability of the structure.
[0053] As an optional implementation, a heating element is provided inside the bottom compartment 200 of this embodiment. The heating element can be a heating wire or a heating rod, etc.
[0054] Since the bottom of the culture chamber 300 has eliminated the sinking motor chamber and the drive device 2 is placed on the side, the bottom of the culture chamber 300 is flat. Therefore, a heating element can be installed in the bottom chamber 200 to heat the bottom of the culture chamber 300.
[0055] As an optional implementation, in this embodiment, heating elements are provided on all six side walls of the culture chamber 300, thereby heating the culture chamber 300 from six sides.
[0056] The oscillation drive mechanism mounting structure in this embodiment solves four major problems. Problem 1: In the existing technology, the submerged motor chamber is located in the downward-facing recessed space at the bottom of the culture chamber 300 and is connected to the culture chamber 300. The complex temperature and humidity environment inside the culture chamber, and the frequent tipping or dropping of experimental samples due to improper handling, easily cause contaminants to accumulate at the bottom of the culture chamber and inside the motor chamber. This makes the motor chamber prone to accumulating dirt and grime, which is difficult to clean and leads to contamination of the culture environment. Problem 2: The motor's drive belt is also located inside the motor chamber. The belt is prone to aging and generating dust over long-term operation, causing suspended particulate pollution in the culture chamber. Problem 3: The motor is located in the submerged motor chamber, which is located in the downward-facing recessed space at the bottom of the culture chamber and is connected to the culture chamber. This means that setting the culture chamber to a high temperature of 160℃~180℃ for sterilization will damage the motor, making it impossible to achieve high-temperature sterilization of 160℃~180℃. Problem 4: The submerged motor chamber is located in the culture chamber. When the culture chamber is heated, it is not conducive to the heat dissipation of the motor. When the high humidity environment is activated for culture, the motor part is also exposed to this environment for a long time. The high temperature and high humidity environment can easily reduce the service life of the motor.
[0057] The beneficial effects of the oscillation drive mechanism mounting structure in this embodiment are as follows:
[0058] 1. The drive device 2 is placed on the side and is located outside the culture chamber 300. It does not directly bear the high temperature inside the culture chamber 300. The culture chamber 300 can reach a higher dry heat sterilization temperature, up to 180℃.
[0059] 2. The machine has a long lifespan and high reliability, which is conducive to heat dissipation of the drive device 2 and can extend the service life of the drive device 2.
[0060] 3. The culture chamber 300 is heated from six sides, so that every part of the inner wall of the culture chamber 300 can be heated to 180 degrees. Compared with circulating heating, the high temperature of the inner wall of the culture chamber 300 is more uniform and comprehensive, without dead corners.
[0061] 4. The drive unit 2 is placed on the side, which makes room for the motor installation in the bottom of the culture chamber 300. The bottom surface of the culture chamber 300 is flat and without dead corners, which increases the area for arranging high-temperature heating wires and provides an easy-to-clean surface to prevent bacterial accumulation.
[0062] Example 2
[0063] This embodiment provides a shaking incubator, including a chamber body 1 and a shaking drive mechanism, which is assembled inside the chamber body 1 through the above-mentioned shaking drive mechanism mounting structure.
[0064] The shaking incubator of this embodiment can extend its service life, facilitate heat dissipation of the drive device 2, and facilitate high-temperature sterilization.
