DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] like Figure 1 and Figure 2 As shown, a culture solution replacement device for shiitake mushroom strain production proposed by an embodiment of the utility model comprises a culture box 1, and a box cover 2 fixedly connected to the upper part of the culture box 1. Shiitake mushroom strains are cultured through the culture box 1, and the box cover 2 realizes the protection of the top of the culture box 1. An automatic prompt mechanism 3 for replacing nutrient solution is installed on the box cover 2. When the nutrient solution is used for a certain period of time, the automatic prompt mechanism 3 for replacing nutrient solution can be used to prompt the staff to replace the nutrient solution in time, so as to avoid the problem that the nutrient solution cannot be replaced in time and affects the growth of shiitake mushroom strains. The automatic prompt mechanism 3 for replacing nutrient solution comprises a telescopic rod 302 slidably connected to the box cover 2. The upper end of the telescopic rod 302 extends to the top of the box cover 2 and is fixed with a top plate 304. The lower surface of the top plate 304 is fixedly connected with a pressing block 305. The longer the time, the lower the level of the nutrient solution in the culture box 1. At this time, The position of the telescopic rod 302 is lowered, thereby lowering the height of the top plate 304 and the pressing block 305. The automatic prompt mechanism 3 for replacing the nutrient solution also includes a base 3010 fixedly connected to the upper surface of the box cover 2. A telescopic plate 307 is slidably connected to the limit rod 309 fixed on the upper surface of the base 3010, and a switch contact 306 is installed on the upper surface of the telescopic plate 307 corresponding to the pressing block 305. When the position of the top plate 304 moves down a certain value, the pressing block 305 and the switch contact 306 are in contact. A rechargeable lithium battery 6 and a prompter 7 are respectively installed on the insulating mounting plate 8 fixed on the upper surface of the box cover 2. The rechargeable lithium battery 6, the prompter 7 and the switch contact 306 are connected in series. When the pressing block 305 and the switch contact 306 are in contact, the circuit between the rechargeable lithium battery 6, the prompter 7 and the switch contact 306 can be closed, thereby making the prompter 7 work to provide prompts to the staff.

[0024] like Figure 2 As shown, in some embodiments, a spring 308 is sleeved on the limit rod 309, and the two ends of the spring 308 are respectively fixedly connected to the base 3010 and the telescopic plate 307. The spring 308 realizes the damping support function of the telescopic plate 307, which can make the switch contact 306 and the telescopic plate 307 drop to a certain extent, thereby preventing the switch contact 306 from being excessively squeezed.

[0025] like Figure 1and Figure 2 As shown, in some embodiments, the upper surface of the box cover 2 is fixedly connected to the limiting seat 303, and the telescopic rod 302 is slidably connected to the limiting seat 303, which plays a limiting role when the telescopic rod 302 is extended or retracted.

[0026] like Figure 2 As shown, in some embodiments, the lower end of the telescopic rod 302 is fixedly connected to a floating plate 301, and the floating plate 301 floats on the nutrient solution, so that the telescopic rod 302 changes with the change of the liquid level.

[0027] like Figure 1 and Figure 3 As shown, in some embodiments, the box cover 2 is connected with a liquid inlet pipe 4 to realize the feeding of nutrient solution, and a disinfection component 5 is installed on the liquid inlet pipe 4, and the incoming nutrient solution is disinfected by the disinfection component 5. The disinfection component 5 includes a sealing plate 501 fixed on the liquid inlet pipe 4, and a plurality of support plates 502 arranged on the sealing plate 501. The support plates 502 extend into the liquid inlet pipe 4 and are installed with sterilization lamps 503 to realize sterilization treatment of the disinfectant and prevent external bacteria from entering the incubator 1.

[0028] The working principle and use steps of the utility model are as follows: the nutrient solution enters the incubator 1 through the liquid inlet pipe 4. After a certain period of time, the liquid level of the nutrient solution will drop, and the floating plate 301 will float on the nutrient solution. When the liquid level of the nutrient solution drops, the floating plate 301 and the telescopic rod 302 will move down accordingly. When the nutrient solution is insufficient and needs to be replaced, the top plate 304 will drop so that the pressing block 305 will drop accordingly. The pressing block 305 will contact the switch contact 306, and the circuit between the switch contact 306, the rechargeable lithium battery 6 and the prompter 7 will be connected, so that the prompter 7 will work, prompting the staff in time, and the staff will replace the nutrient solution according to the prompt, thereby ensuring the timely replacement of the nutrient solution.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
