Description

Technical Field

[0001] This utility model relates to the field of incubation shaker technology, and in particular to a constant temperature incubation shaker. Background Technology

[0002] In biochemistry and molecular biology laboratories, the isothermal incubator shaker is an indispensable piece of laboratory equipment. An isothermal incubator shaker is a biochemical instrument combining a temperature-controlled incubator and a shaker. It is a device capable of incubating and shaking samples at a constant temperature. Its function is to ensure that samples undergo incubation steps in a constant-temperature working environment and to shake and mix various reaction reagents within the incubator, ensuring thorough reaction between the sample and reagents. For example, in Western blotting experiments, antibody incubation can be performed at low temperatures. Therefore, isothermal incubator shakers are widely used in fields requiring high temperature and oscillation frequency control, such as cell culture, fermentation, hybridization, biochemistry, and enzyme and cell tissue research.

[0003] Currently, most commercially available constant-temperature incubation shakers use compressor cooling for temperature control, with the lower part of the shaker connected to an eccentric mechanism via a rotating component. However, existing constant-temperature incubation shakers can only cool but not heat, resulting in a limited temperature control range and imprecise temperature control, leading to unstable temperatures and affecting the incubation effect. Furthermore, existing constant-temperature incubation shakers generate significant noise during oscillation, and the friction between the eccentric mechanism and the incubation platform is high, causing significant shaking of the platform during high-speed oscillation, which also affects the incubation effect during constant-temperature incubation. Utility Model Content

[0004] To address the technical problems of existing constant temperature incubation shakers having limited temperature control range and insufficient temperature control precision, and the incubation platform being prone to significant shaking during high-speed oscillation, thus affecting the incubation effect, this utility model provides the following technical solution.

[0005] This utility model discloses a constant temperature incubation shaker, comprising a housing with an incubation chamber and a side door. A temperature control box with a temperature control chamber and a display screen is connected to one side of the housing. The temperature control chamber contains a semiconductor cooling chip and a ceramic heating plate. A temperature control fan is connected through the temperature control chamber and the incubation chamber. A base supporting a shock-absorbing component is provided at the bottom of the incubation chamber. A brushless motor is fixedly connected to the center of the upper part of the base. An eccentric wheel is connected to the output end of the brushless motor. An incubation platform supporting the incubation box is fixedly connected to the upper end of the eccentric wheel. The lower part of the incubation platform is connected to the shock-absorbing component, which includes a silicone groove that abuts against the lower part of the incubation platform.

[0006] As a further technical solution, a number of support columns are fixedly provided at the lower part of the incubation platform, and the lower ends of the support columns rotate within the silicone tank.

[0007] As a further technical solution, the shock-absorbing component includes a fixing plate fixed to the upper part of the base and a damping pad located at the upper end of the fixing plate, wherein a spring is fixedly connected to the upper end of the damping pad and to the lower end of the silicone groove.

[0008] As a further technical solution, the spring is provided with a telescopic sleeve that is fixedly connected to the damping pad and the silicone groove in the axial direction.

[0009] As a further technical solution, the damping pad is made of a damping metal material.

[0010] As a further technical solution, the incubation chamber is equipped with a cooling fan and several temperature sensors.

[0011] The beneficial effects of this invention are as follows: The temperature control chamber is equipped with a semiconductor cooling chip and a ceramic heating plate. Heat is blown into the incubation chamber by a temperature-controlled fan, effectively controlling the temperature within the chamber. Combined with a cooling fan on one side of the chamber, this improves the accuracy of temperature control and ensures a constant-temperature incubation effect. A brushless motor and eccentric wheel are connected below the incubation platform, enabling effective oscillation. Shock-absorbing components are connected around the lower perimeter of the incubation platform to reduce vibration and friction during high-speed oscillation, effectively mitigating shock and ensuring the stability and effectiveness of the incubation during constant-temperature incubation.

[0020] like Figure 1 and Figure 2 As shown, this utility model discloses a constant temperature incubation shaker, comprising a housing 1 and a temperature control box 2. The housing 1 is used for constant temperature incubation, and the temperature control box 2 is used to provide the temperature required for incubation. The housing 1 has a hollow structure and contains an incubation chamber 101, with a side door 102 covering one side of the incubation chamber 101. The temperature control box 2 contains a temperature control chamber 201, and a display screen 202 is located on the outside of the temperature control box 2. The display screen 202 is connected to an existing PID temperature control system for effectively controlling the temperature required for constant temperature incubation.

[0021] In a preferred embodiment, the temperature control cavity 201 is equipped with a semiconductor cooling chip 3 and a ceramic heating plate 4, which are electrically connected to an existing PID temperature control system. The heat sink on one side of the semiconductor cooling chip 3 is located outside the temperature control box 2, while its cooling surface is located inside the temperature control cavity 201. The ceramic heating plate 4 is located on the bottom plate of the temperature control cavity 201, providing a constant temperature for incubation experiments requiring 25-60 degrees Celsius. A temperature control fan 5 is connected through the temperature control cavity 201 and the incubation cavity 101, blowing cold or hot air from the temperature control cavity 201 into the incubation cavity 101 to provide a stable temperature for the incubation cavity 101.

[0022] In addition, the incubation chamber 101 is equipped with a cooling fan and several temperature sensors. The cooling fan can accelerate the heat flow in the incubation chamber 101, and the multiple temperature sensors are distributed at multiple points in the incubation chamber 101 to monitor the temperature in the incubation chamber 101 in real time.

[0023] like Figure 3 and Figure 4 As shown, in a preferred embodiment, a base 103 is fixedly provided at the bottom of the incubation chamber 101. The base 103 supports a shock-absorbing component 6. A brushless motor 9 is fixedly connected to the center of the upper part of the base 103. An eccentric wheel 10 is connected to the output end of the brushless motor 9. An incubation platform 7 carrying the incubation box 8 is fixedly connected to the upper end of the eccentric wheel 10. The high-speed oscillation of the incubation platform 7 is controlled by the brushless motor 9. The lower part of the incubation platform 7 is connected to the shock-absorbing component 6, which is used to dampen the incubation platform 7 during the oscillation process, preventing it from experiencing large vibrations and friction, and ensuring the stability of the incubation platform 7.

[0024] In a preferred embodiment, the shock-absorbing component 6 includes a silicone groove 603 that abuts against the lower part of the incubation platform 7. The silicone groove 603 is smoothed. Several support columns 701 are fixedly installed on the lower part of the incubation platform 7. In this embodiment, there are four support columns 701, located around the perimeter of the incubation platform 7. The lower ends of the support columns 701 can rotate within the silicone groove 603. When the brushless motor 9 drives the incubation platform 7 to oscillate and rotate, the four support columns 701 rotate within the four silicone grooves 603 respectively, effectively reducing the vibration of the incubation platform 7.

[0025] like Figure 5 As shown, in a preferred embodiment, the shock-absorbing component 6 includes a fixing plate 601 fixed to the upper part of the base 103, and a damping pad 602 is connected to the upper end of the fixing plate 601. In this embodiment, there are two fixing plates 601. Of course, only one fixing plate 601 can be provided, as long as a total of four damping pads 602 are connected to all the fixing plates 601. This utility model does not make any special limitation on it.

[0026] The damping pad 602 is made of damping metal material. A spring 604, which is fixedly connected to the lower end of the silicone groove 603, is fixedly connected to the upper end of the damping pad 602. A telescopic sleeve 605, which is fixedly connected to the damping pad 602 and the silicone groove 603, is axially mounted on the spring 604. When the incubation platform 7 oscillates, the support column 701 rotates within the silicone groove 603. The spring 604 and the damping pad 602 further dampen the vibration, ensuring the oscillation stability of the incubation platform 7.
