Description

Technical Field

[0001] This utility model relates to a plant tissue culture device with adjustable light intensity, and specifically to a plant tissue culture device with adjustable light intensity. Background Technology

[0002] Plant tissue culture technology requires providing a precise and controllable growth environment for ex vivo plant materials (such as cells, tissues, and organs). Among these factors, light intensity, temperature stability, and environmental quietness are key factors affecting the success rate of culture. In practical applications, traditional plant tissue culture devices often suffer from problems such as insufficient precision in light regulation, low heat dissipation efficiency, and high operating noise, which limit the culture results.

[0003] Traditional devices often rely on simple switching of lamps or adjusting light at fixed distances, making it difficult to achieve continuous and precise intensity gradient control. Furthermore, direct light from the source can lead to uneven lighting in the cultivation area, resulting in significant differences in the growth status of seedlings at the edges and center. Additionally, the heat generated by the light source and drive components during operation can easily accumulate inside the device. If heat dissipation is not timely, the internal temperature can exceed the suitable range for plants, affecting tissue differentiation and seedling growth. Utility Model Content

[0004] This invention provides a plant tissue culture device with adjustable light intensity. One purpose is to provide light intensity adjustment function to solve the problems of rough and uneven light intensity adjustment in traditional devices. Another purpose is to solve the problem of high internal temperature caused by insufficient heat dissipation in traditional devices, so as to ensure the stability of the culture environment temperature.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An adjustable light intensity plant tissue culture device includes a shell, an isolation plate fixedly connected inside the shell and a shelf fixedly connected below the isolation plate, a door rotatably connected to the shell behind the shelf, an adjustment device and a cooling device fixedly connected above the isolation plate, and an inspection door rotatably connected to the shell above the adjustment device and the cooling device.

[0007] A further improvement of this utility model is that: a gradient light-transmitting disk is rotatably connected above the isolation plate, a ring of gradient light-transmitting holes is opened above the gradient light-transmitting disk, an external gear ring is fixedly connected to the outer side of the gradient light-transmitting disk, a gear is meshed in front of the external gear ring, the gear and the isolation plate are rotatably connected, a motor mounting bracket is fixedly connected above the gear on the housing, a motor is fixedly connected above the motor mounting bracket, and the output shaft of the motor is fixedly connected to the gear.

[0008] A further improvement of the present invention is that: a support frame is fixedly connected above the isolation plate of the housing, a light source is fixedly connected below the support frame, and a light-emitting hole is opened below the light source in the isolation plate and a scattering lens is fixedly connected thereto.

[0009] A further improvement of the present invention is that: several heat dissipation fins are fixedly connected above the gradient light-transmitting disc and the first support frame; the second support frame is fixedly connected to the right side of the housing; and air inlets and air outlets are respectively opened on the left and right sides of the housing.

[0010] A further improvement of the present invention is that: an air inlet is provided on the left side of the second support frame; a perforated plate is fixedly connected inside the second support frame and divides it into front and rear chambers; sound-absorbing cotton is fixedly connected to the side walls of both the front and rear chambers of the perforated plate; and a cover plate is fixedly connected to the top of the second support frame.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0013] 1. This utility model provides a plant tissue culture device with adjustable light intensity. The light emitted by the light source is transmitted downward to the light outlet of the isolation plate. After being scattered by the scattering lens fixed in the light outlet, it forms uniform light that shines on the culture material on the shelf below. At the same time, the gradient light-transmitting disk above the isolation plate meshes with the gear through the outer toothed ring. The motor drives the gear to rotate, which in turn drives the gradient light-transmitting disk to rotate.

[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0022] like Figure 1 As shown, this utility model provides a plant tissue culture device with adjustable light intensity, including a shell 1. An isolation plate 4 is fixedly connected inside the shell 1, and a shelf 3 is fixedly connected below the isolation plate 4. A door 2 is rotatably connected to the rear of the shell 1 and the shelf 3. An adjustment device 5 and a cooling device 7 are fixedly connected above the isolation plate 4. An inspection door 6 is rotatably connected above the adjustment device 5 and the cooling device 7. The shell 1 serves as the main body of the device and is rotatably connected to the door 2 at the front for taking out the culture material on the shelf 3. The interior is divided into upper and lower layers by the isolation plate 4. The lower layer is the culture area, and the upper layer integrates the adjustment device 5 and the cooling device 7 to realize the functions of light and heat dissipation.

[0023] like Figure 2As shown, this utility model provides a technical solution: A gradient light-transmitting disk 52 is rotatably connected above the isolation plate 4. A ring of gradient light-transmitting holes is opened above the gradient light-transmitting disk 52. An external gear ring 51 is fixedly connected to the outer side of the gradient light-transmitting disk 52. A gear 53 is meshed in front of the external gear ring 51. The gear 53 and the isolation plate 4 are rotatably connected. A motor mounting bracket 55 is fixedly connected above the gear 53 in the housing 1. A motor 54 is fixedly connected above the motor mounting bracket 55. The output shaft of the motor 54 is fixedly connected to the gear 53. When the motor 54 rotates, its output shaft drives the gear 53 to rotate. Then, the gear 53 meshes with the external gear ring 51 on the outer side of the gradient light-transmitting disk 52, causing the gradient light-transmitting disk 52 to rotate above the isolation plate 4. The light-transmitting area is changed by rotating the gradient light-transmitting holes on the gradient light-transmitting disk 52, thereby dynamically adjusting the amount of light passing through and realizing the control of light intensity.

[0024] like Figure 3 As shown, this utility model provides a technical solution: a support frame 56 is fixedly connected above the isolation plate 4 in the housing 1, and a light source 57 is fixedly connected below the support frame 56. The isolation plate 4 has a light outlet hole below the light source 57 and a scattering lens 58 is fixedly connected thereto. The light source 57 installed below the support frame 56 serves as the light output source. At the same time, the direct light emitted by the light source 57 is transmitted downward to the light outlet hole of the isolation plate 4. After being scattered by the scattering lens 58 fixed in the light outlet hole, it is converted into uniform and soft light, avoiding local strong light and ensuring that the culture material on the shelf 3 receives uniform light.

[0025] like Figure 4 As shown, this utility model provides a technical solution: several heat dissipation fins 71 are fixedly connected above the gradient light-transmitting disc 52 and the support frame 1 56. The housing 1 is fixedly connected to the support frame 2 72 on the right side of the support frame 1 56. Air inlets and air outlets are opened on the left and right sides of the housing 1, respectively. An air inlet is opened on the left side of the support frame 2 72. A perforated plate 74 is fixedly connected inside the support frame 2 72, which is divided into front and rear chambers by the perforated plate 74. Sound-absorbing cotton 73 is fixedly connected to the side walls of the front and rear chambers of the support frame 2 72. A cover plate 75 is fixedly connected above the support frame 2 72. The heat generated when the light source 57 is working is transferred to the support frame 1 56. The heat generated when the gradient light-transmitting disc 52 is running is directly conducted to its own surface. At the same time, the heat dissipation fins 71 fixed above the support frame 1 56 and the gradient light-transmitting disc 52 increase the heat dissipation area and quickly conduct the heat to the surrounding air, reducing the accumulation of local high temperature.

[0026] like Figure 5As shown, this utility model provides a technical solution: a rubber pad 76 is fixedly connected to the bottom of the cover plate 75, a rubber pad 78 is fixedly connected to the front of the perforated plate 74 in the support frame 72, a fan mounting bracket 79 is fixedly connected to the top of the rubber pad 78, and a fan 77 is fixedly connected to the top of the fan mounting bracket 79. Hot airflow enters the rear chamber through the front chamber separated by the perforated plate 74. The perforated plate 74 buffers the airflow and enhances heat dissipation, and finally discharges through the air outlet of the housing 1. The vibration generated by the fan 77 during operation is absorbed by the bottom rubber pad 78. At the same time, the rubber pad 76 under the cover plate 75 further weakens the structural resonance, and the turbulence noise generated by the airflow through the perforated plate 74 is absorbed by the sound-absorbing cotton 73 on the side walls of the front and rear chambers of the support frame 72, reducing the noise radiated outward.

[0027] The working principle of this plant tissue culture device with adjustable light intensity will be explained in detail below.

[0028] like Figure 1-5 As shown, a light source 57 is fixed below the support frame 56 inside the housing 1. The light emitted by the light source 57 is transmitted downward to the light outlet of the isolation plate 4. After being scattered by the scattering lens 58 fixed in the light outlet, it forms uniform light that illuminates the culture material on the lower shelf 3. At the same time, the gradient light-transmitting disk 52 above the isolation plate 4 meshes with the gear 53 through the outer toothed ring 51. The motor 54 drives the gear 53 to rotate, which in turn drives the gradient light-transmitting disk 52 to rotate. The gradient light-transmitting hole on the disk changes the light-transmitting area as it rotates, thereby continuously adjusting the amount of light passing through and realizing the adjustment of the light intensity. The heat generated by the light source 57 and the gradient light-transmitting disk 52 during operation is quickly conducted to the air through the heat dissipation fins 71 fixed above, increasing the heat dissipation area to accelerate heat dissipation. Meanwhile, inside the support frame 72 on the right side of the housing 1, the fan 77 is connected to the left side. The air inlet draws in hot air from inside the device. The hot air enters the rear chamber through the front chamber separated by the perforated plate 74, and is finally discharged through the air outlet of the casing 1. The perforated plate 74 not only buffers the airflow, but also enhances the heat dissipation efficiency through the air circulation between the front and rear chambers, preventing high temperature accumulation inside the device. The vibration of the fan 77 during operation is absorbed by the rubber pad 78 at the bottom, thereby reducing the transmission of vibration to the support frame 72. Furthermore, the rubber pad 76 under the cover plate 75 further weakens the structural resonance noise. At the same time, the turbulence noise generated when the airflow passes through the perforated plate 74 is absorbed by the sound-absorbing cotton 73 fixed to the side walls of the front and rear chambers of the support frame 72, reducing the intensity of noise radiation and achieving low-noise operation. The device closes the shelf 3 area through the door 2 to isolate external pollution, while the maintenance door 6 facilitates the maintenance of the adjustment device 5 and the cooling device 7.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
