[0001] The utility model belongs to the technical field of potato tissue culture, and particularly relates to a potato tissue culture lighting device. Background Art

[0002] During potato tissue culture, the light and temperature inside the tissue culture flask need to be strictly controlled. The light is usually controlled by the lighting lamps installed around the tissue culture flask. However, as the lighting lamps continue to work, they will continue to convert light energy into heat energy, causing the temperature around the tissue culture flask to rise, making it difficult to stably control the temperature inside the tissue culture flask. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] Specific implementation examples Figure 1-5 As shown, the utility model provides a potato tissue culture lighting device, comprising a trough-shaped tissue culture tank 1 and a lighting lamp 2 fixed on the tissue culture tank 1, a tissue culture bottle 3 is fixed in the tissue culture tank 1, and multiple groups of the lighting lamps 2 are arranged on the inner tank side wall of the tissue culture tank 1, and the side wall of the tissue culture tank 1 is provided with a water hole 4 penetrating the tissue culture tank 1 in the vertical direction, and the water hole 4 is adjacent to the lighting lamp 2. The water inlet end of the water hole 4 of the tissue culture tank 1 is connected to the output end of the circulating medium, and the water outlet end of the water hole 4 of the tissue culture tank 1 is connected to the recovery end of the circulating medium, and the circulating medium in the water hole 4 carries away the heat generated by the lighting lamp 2.

[0021] During potato tissue culture, the light and temperature in the tissue culture bottle 3 need to be strictly controlled. The light is usually controlled by the lighting lamp 2 set on the side of the tissue culture bottle 3. However, as the lighting lamp 2 continues to work, it will continue to convert light energy into heat energy, causing the temperature around the tissue culture bottle 3 to rise, making it difficult to stably control the temperature in the tissue culture bottle 3.

[0022] Therefore, in the present invention, the lighting lamp 2 is fixed to the side wall of the tissue culture tank 1, and a water hole 4 is provided on the side wall of the tissue culture tank 1. The circulating medium used in the specific embodiment is water. The circulating medium that continuously circulates in the water hole 4 carries away the heat generated by the lighting lamp 2. Compared with the cooling method such as the fan in the prior art, the fan cooling is to cool the tissue culture bottle 3, but the heat generated by the lighting lamp 2 will still be transferred to the tissue culture bottle 3. That is, the cooling method is to keep the temperature in the tissue culture bottle 3 at the average temperature within a certain range. In fact, the temperature in the tissue culture bottle 3 is always changing and the temperature is not stable. In the present invention, the heat of the lighting lamp 2 is directly carried away, eliminating the heat from the root, preventing the heat from being transferred to the tissue culture bottle 3, and thus achieving a truly stable control of the temperature in the tissue culture bottle 3.

[0023] like Figure 1-5 As shown, the tissue culture tank 1 is provided with multiple groups up and down, the water inlet end of the water hole 4 protrudes outward and forms a plug-in part 5, the water outlet end diameter of the water hole 4 increases and forms a fixed groove 6 matching the plug-in part 5, the fixed groove 6 of the upper-level tissue culture tank 1 is plugged into the plug-in part 5 of the lower-level tissue culture tank 1, and the multiple groups of water holes 4 of the tissue culture tank 1 are interconnected and form a cooling channel. The water holes 4 in the utility model can not only be used as a cooling channel for the circulation medium to flow, but also play the role of a plug-in component, so that multiple groups of tissue culture tanks 1 are plugged into each other to form a tissue culture rack, thereby saving space. At the same time, the circulating medium can also pass through the lighting lamps 2 of the multiple groups of tissue culture tanks 1 to cool the multiple groups of lighting lamps 2, thereby improving the recycling rate of the circulating medium.

[0024] like Figure 2 As shown, the four corners of the inner groove of the tissue culture tank 1 are respectively provided with slots 7 along the vertical direction for the lighting lamp 2 to be plugged in and fixed. The slots 7 include two groups of symmetrically arranged L-shaped baffles. The two groups of baffles are arranged at intervals to form a gap for the light of the lighting lamp 2 to pass through. The plug-in method facilitates the installation and replacement of the lighting lamp 2. At the same time, the gap can ensure that the light can smoothly pass through the slots 7 and shine on the tissue culture bottle 3.

[0025] like Figure 1As shown, a diverter trough 8 is provided on the top of the tissue culture tank 1, and a plurality of through holes are provided on the diverter trough 8 which are connected to the water inlet end of the water hole 4. The water hole 4 is connected to the output end of the circulating medium by means of the diverter trough 8. In order to reduce the number of diverter components between the circulating medium supply device and the water hole 4, a diverter trough 8 is also provided in the utility model. The through hole of the diverter trough 8 is slightly smaller than the water hole 4 and is inserted into the water hole 4 to form a connection. The circulating medium in the diverter trough 8 is diverted by the diverter trough 8 with a plurality of through holes. Therefore, during operation, it is only necessary to install the diverter trough 8 above the topmost tissue culture tank 1 of the multi-layer tissue culture tank 1, and align the output end of the circulating medium supply device with the diverter trough 8, without setting a plurality of diverter components. In addition, a drainage trough 13 is provided below the bottom tissue culture tank 1. The multiple water holes 4 of the tissue culture tank 1 are all located in the drainage trough 13. The drainage trough 13 is provided with only one drainage hole 4 and is connected to the circulating medium recovery end 12. The circulating medium re-enters the circulating medium output end 11 from the circulating medium recovery end 12 with the help of a water pump and flows into the diversion trough to form a cycle. At the same time, the larger surface area of ​​the diversion trough is used to dissipate heat from the circulating medium carrying heat in the diversion trough.

[0026] like Figure 1 As shown, the inner wall of the tissue culture tank 1 is provided with a reflective plate 9. The light generated by the lighting lamp 2 is reflected by the reflective plate 9 and illuminates the tissue culture bottle 3. The reflective plate 9 is used to increase the utilization rate of the light generated by the lighting lamp 2, so that the potato tissue culture seedlings can obtain sufficient light. This method does not change the number and power of the lighting lamps 2, reduces the total heat dissipation of the lighting lamps 2 in the tissue culture tank 1, and thus reduces the fluctuation of the ambient temperature.

[0027] like Figure 1 As shown, the side wall of the tissue culture tank 1 is provided with ventilation holes 10, and the ventilation holes 10 can be used to ventilate and cool the tissue culture tank 1.
