Description

Technical Field

[0001] The utility model belongs to the technical field of tissue culture, and in particular relates to a potato tissue culture device with stable environmental temperature. Background Art

[0002] Potato tissue culture is mainly used for the rapid propagation of virus-free potato seedlings. In addition to sterile operation, the tissue culture process also requires strict control of culture temperature and lighting duration. Since potato tissue culture seedlings should avoid direct sunlight and excessive exposure, lighting sets are usually used to provide light for potato tissue culture seedlings.

[0003] Currently, in order to obtain sufficient light, the number of lighting lamps is usually increased or the power of the lighting lamps is increased. However, both of the above methods will increase the heat generated by the lighting lamp group, making it difficult to strictly control the culture temperature, affecting the growth of potato tissue culture seedlings. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a potato tissue culture device with a stable ambient temperature. By adding a reflector, the reflector is used to increase the utilization rate of the light generated by the lighting lamp group, so that the potato tissue culture seedlings can obtain sufficient light. This method does not change the number and power of the lighting lamps, reduces the heat dissipation of the lighting lamps, thereby reducing the fluctuation of the ambient temperature. At the same time, the temperature of the tissue culture bottles is further controlled by the water cooling tray.

[0005] The specific technical solution adopted in this utility model is:

[0006] A potato tissue culture device with a stable ambient temperature comprises a tissue culture rack and a lighting device fixed to the tissue culture rack. The tissue culture rack is provided with a partition for holding tissue culture bottles. The lighting device comprises a lighting lamp and a reflective plate. The lighting lamp is fixed above the tissue culture bottle by means of the tissue culture rack. The reflective plate is provided in multiple groups around the tissue culture bottle. The light generated by the lighting lamp is reflected by the reflective plate and illuminates the circumference of the tissue culture bottle.

[0007] A water cooling tray is also provided between the tissue culture bottle and the partition. The surface of the water cooling tray is provided with a limiting groove that matches the shape of the bottom of the tissue culture bottle. The tissue culture bottle is fixedly connected to the water cooling tray with the help of the limiting groove. The cooling medium input end and the cooling medium output end of the water cooling tray are respectively connected to the circulating water input pipe and the circulating water output pipe.

[0008] A T-shaped slider is provided at the bottom of the water cooling tray, and a dovetail groove matching the slider is provided on the partition surface of the tissue culture rack. The water cooling tray is plugged and fixed to the tissue culture rack by means of the slider.

[0009] One end of the dovetail groove is closed and forms a positioning portion of the dovetail groove. The slider of the water cooling tray abuts against the positioning portion of the limit groove and forms a positioning. The tissue culture bottle on the water cooling tray is located below the lighting lamp by means of the positioning portion.

[0010] The water cooling tray is provided with a plurality of fixing components in a rectangular array. The fixing components include a plurality of slide rails arranged in a ring array with the limiting groove as the center. The reflective plate is plugged and matched with the slide rails to form a detachable fixed connection.

[0011] The beneficial effects of the utility model are:

[0012] The utility model is provided with an additional reflector, which increases the utilization rate of the light generated by the lighting lamp group, so that the potato tissue culture seedlings can obtain sufficient light. This method does not change the number and power of the lighting lamps, reduces the heat dissipation of the lighting lamps, thereby reducing the fluctuation of the ambient temperature, and further controls the temperature of the tissue culture bottle through the water cooling tray.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] Specific implementation examples Figure 1-4 As shown, the utility model provides a potato tissue culture device with a stable ambient temperature, comprising a tissue culture rack 1 and a lighting device fixed on the tissue culture rack 1, wherein the tissue culture rack 1 is provided with a partition 3 for holding a tissue culture bottle 2, and the lighting device comprises a lighting lamp 4 and a reflective plate 5, wherein the lighting lamp 4 is fixed above the tissue culture bottle 2 by means of the tissue culture rack 1, and the reflective plate 5 is provided with multiple groups around the tissue culture bottle 2, and the light generated by the lighting lamp 4 is reflected by the reflective plate 5 and illuminates the tissue culture bottle 2.

[0020] Currently, in order to obtain sufficient light during the potato tissue culture process, the number of lighting lamps 4 is usually increased or the power of the lighting lamps 4 is increased. However, both of the above methods will lead to an increase in the heat generated by the lighting lamps 4, making it difficult to strictly control the culture temperature, affecting the growth of the potato tissue culture seedlings.

[0021] Therefore, the present invention adds a diffuse reflection reflector 5, which increases the utilization rate of the light generated by the group of lighting lamps 4, so that the potato tissue culture seedlings can obtain sufficient light. This method does not change the number and power of the lighting lamps 4, reduces the heat dissipation of the lighting lamps 4, and thus reduces the fluctuation of the ambient temperature.

[0022] like Figure 3 As shown, a water-cooling tray 6 is further provided between the tissue culture bottle 2 and the partition 3. The surface of the water-cooling tray 6 is provided with a limiting groove 7 that matches the shape of the bottom of the tissue culture bottle 2. The tissue culture bottle 2 is fixedly connected to the water-cooling tray 6 with the help of the limiting groove 7. The cooling medium input end and the cooling medium output end of the water-cooling tray 6 are respectively connected to the circulating water input pipe and the circulating water output pipe. When the temperature exceeds 26°C, the potato tissue culture seedlings will stop growing, and the lighting lamp 4 will generate heat during the illumination process. Therefore, a water-cooling tray 6 is provided to cool the tissue culture bottle 2, further control the temperature inside the tissue culture bottle 2, and prevent the lamp temperature generated by the lighting lamp 4 from affecting the growth of the potato tissue culture seedlings.

[0023] like Figure 2 and Figure 4 As shown, a T-shaped slider 8 is provided at the bottom of the water-cooling tray 6, and a dovetail groove 9 matching the slider 8 is provided on the surface of the partition 3 of the tissue culture rack 1. The water-cooling tray 6 is plugged and fixed to the tissue culture rack 1 with the help of the slider 8. In order to improve space utilization, the compartment height of the tissue culture rack 1 is relatively low, so it is inconvenient to place the tissue culture bottle 2, and the water-cooling tray 6 facilitates the placement of the tissue culture bottle 2. When placing the tissue culture bottle 2, first slide the water-cooling tray 6 out, then fix the tissue culture bottle 2 and the reflector 5 to the water-cooling tray 6 on a spacious workbench, and then put the water-cooling tray 6 with the tissue culture bottle 2 and the reflector 5 placed back into the tissue culture rack 1.

[0024] like Figure 4 As shown, one end of the dovetail groove 9 is closed and forms a positioning portion 10 of the dovetail groove 9. The slider 8 of the water-cooling tray 6 abuts against the positioning portion 10 of the limit groove 7 and forms a positioning. The tissue culture bottle 2 on the water-cooling tray 6 is located below the lighting lamp 4 with the help of the positioning portion 10. Since the water-cooling tray 6 needs to be disassembled and installed repeatedly, in order to ensure that the tissue culture bottle 2 is always located directly below the lighting lamp 4, the utility model is also provided with a positioning portion 10. When the slider 8 of the water-cooling tray 6 abuts against the positioning portion 10, the tissue culture bottle 2 is located just below the lighting lamp 4, and the reflection of the reflector 5 is used to ensure that the utilization rate of the light of the lighting lamp 4 is maximized.

[0025] like Figure 3 As shown, the water-cooling tray 6 is provided with multiple sets of fixing components in a rectangular array. These fixing components include multiple sets of slide rails 11 arranged in a ring-shaped array centered on the limiting groove 7. The reflective plate 5 is plugged and matched with the slide rails 11 to form a removable fixed connection. The reflective plate 5 in the present invention is fixedly connected to the water-cooling tray 6 by means of the slide rails 11. The slide rails 11 not only ensure that the reflective plate 5 is arranged in a vertical direction, but also require different light intensities at different growth stages of potato tissue culture seedlings. According to the different growth stages of potato tissue culture seedlings, the number of reflective plates 5 around the tissue culture bottle 2 can be increased or decreased, thereby increasing or decreasing the light utilization rate and thus adjusting the light intensity.
