A mist spraying mechanism 2 is arranged on the left side of the top wall of the carrier plate 12, which is a mechanism for providing mist spraying during the germination acceleration process;

[0034] Specifically, first place the pepper seeds on the gauze 10 inside the germination box 6. The germination box 6 is connected to the germination chamber 3 through the loading slot 5 and can slide inside the germination chamber 3 for convenient picking and placing. The atomizing spraying mechanism 2 on the left side of the top wall of the carrier plate 12 starts to work, spraying water in an atomized state into the germination chamber 3. A plurality of side sliding strips 4 fixed at equal distances on the left and right sides of the inner wall of the germination chamber 3 can play a role in guiding and supporting the germination box 6, and at the same time ensure the stable position of the germination box 6 inside the germination chamber 3, so that the atomized water can be evenly sprayed into each germination box 6.

[0035] Refer to Figure 2 、 Figure 3 and Figure 4 As shown in, the atomizing spraying mechanism 2 includes a water tank 201 for storing water. A water pump 202 is fixedly connected to the right side of the top wall of the carrier plate 12. The water pump 202 is used to provide power to pump out the water. The rear end of the water pump 202 is communicated with the right side of the water tank 201 to realize the pumping of water. The top end of the water pump 202 is communicated with an output pipe 203 for conveying water. A plurality of shunt pipes 204 are equidistantly communicated with the front side of the output pipe 203. The shunt pipes 204 are used to shunt the water. A plurality of branch pipes 205 are communicated with both the left and right sides of the plurality of shunt pipes 204 to further shunt the water. A plurality of atomizing nozzles 206 are communicated with the bottom walls of the plurality of branch pipes 205, and the atomizing nozzles 206 spray the water in an atomized state. A water circulation component is arranged on the inner bottom wall of the germination chamber 3, and this component is used to realize the recycling of water;

[0036] Specifically, the water in the water tank 201 is pumped out by starting the water pump 202. The pumped water enters the output pipe 203 connected to the top of the water pump 202. Subsequently, the water flow moves forward along the output pipe 203. When the water flow reaches a plurality of shunt pipes 204 connected equidistantly on the front side of the output pipe 203, the water flow is shunted into each shunt pipe 204. A plurality of branch pipes 205 are connected to the left and right sides of each shunt pipe 204, and the water is further distributed into these branch pipes 205. Finally, the water is sprayed out from a plurality of atomizing nozzles 206 connected to the bottom wall of the branch pipes 205 to form a fine water mist. These atomizing nozzles 206 are evenly distributed in the germination box 3, which can ensure that the water mist is evenly sprayed into each germination box 6, providing sufficient and uniform moisture for the pepper seeds. The water circulation component arranged on the inner bottom wall of the germination box 3 can collect and process the excess water so that it can return to the water tank 201 again for recycling, improving the utilization rate of water resources and ensuring the humidity stability of the germination environment. The atomizing spray mechanism 2 continuously provides suitable humidity conditions for the germination process of the pepper seeds, promoting the smooth germination and growth of the seeds.

[0037] Refer to Figure 5 , the water circulation component includes a return pipe 13. The return pipe 13 is used to return the water in the germination box 3. The top of the return pipe 13 penetrates through the middle part of the bottom wall of the working plate 1 and is connected to the inner bottom wall of the germination box 3 to realize the water return path. Flange heads 14 are connected to both the upper middle part and the lower middle part of the return pipe 13. The flange heads 14 are used to connect the replaceable filter element 15. The replaceable filter element 15 is fixedly installed between two adjacent flange heads 14. The replaceable filter element 15 is used to filter impurities in the water; Columns 16 are fixedly connected to the four corners of the bottom wall of the working plate 1. The columns 16 are used to support the working plate 1. Anti-slip pads 17 are fixedly connected to the bottom ends of a plurality of columns 16. The anti-slip pads 17 play an anti-slip role; A water injection pipe 18 is connected to the rear side of the water tank 201. The water injection pipe 18 is used to inject water into the water tank 201. The top of the water injection pipe 18 is rotatably connected with a sealing cover 19. The sealing cover 19 is used to seal the water injection pipe 18;

[0038] Specifically, the return pipe 13 in the water circulation component returns the excess water on the inner bottom wall of the germination box 3 to a specific position, realizing the recycling of water resources and avoiding waste. The two flange heads 14 in the middle play a role in connecting and fixing the return pipe 13 and the replaceable filter element 15, ensuring the stability and sealing performance of the entire water circulation system. The columns 16 play a supporting role for the entire working plate 1. The anti-slip pads 17 at the bottom of the columns 16 increase the friction between the columns 16 and the placement plane, preventing the germination device from sliding during operation. The water injection pipe 18 facilitates injecting new water source into the water tank 201. When not injecting water, the sealing cover 19 seals the water injection pipe 18 to prevent dust, sundries, etc. from entering the water tank 201.

[0039] Refer to Figure 1, on the right side of the top wall of the working board 1, there is a console 20 fixedly connected. The console 20 is used to control the operation of the entire device. On the top wall of the console 20, there are multiple control buttons 21 fixedly connected. The control buttons 21 are used for operation and control; on the top wall of the germination box 3, there is an air circulation valve 22 communicated. The air circulation valve 22 is used to ensure the air circulation in the germination box 3. At the top end of the inner wall of the air circulation valve 22, there is a filter screen 23 fixedly connected. The filter screen 23 is used to filter impurities in the air; on the front side of the water tank 201, there is a water pressure gauge 24 fixedly connected. The water pressure gauge 24 is used to display the water pressure in the water tank 201. The water pressure gauge 24 is electrically connected to the water tank 201;

[0040] Specifically, the console 20 serves as the control center, providing an installation position for multiple control buttons 21. The control buttons 21 are used to control the various functions of the germination device. The air circulation valve 22 can ensure the air circulation in the germination box 3, enabling the pepper seeds to obtain sufficient oxygen during the germination process, promoting the respiration and germination process of the seeds. The internal filter screen 23 prevents external dust and impurities from entering the germination box 3 through the air circulation valve 22, maintaining the cleanliness of the germination environment. The water pressure gauge 24 can monitor the water pressure in the water tank 201 in real time. Users can understand whether the water in the water tank 201 is sufficient and whether the working pressure of the atomizing spray mechanism 2 is normal through the water pressure gauge 24, so as to adjust and maintain the device in a timely manner.

[0041] Working principle: First, place the pepper seeds on the gauze 10 in the germination box 6. The germination box 6 is connected to the germination box 3 through the loading slot 5 and can slide in the germination box 3 for easy taking and placing. The atomizing spray mechanism 2 on the left side of the top wall of the carrier plate 12 starts to work, spraying the water in an atomized state into the germination box 3. Multiple side sliding strips 4 fixedly arranged at equal intervals on the left and right sides of the inner wall of the germination box 3 can play a role in guiding and supporting the germination box 6, and at the same time ensure the stable position of the germination box 6 in the germination box 3, so that the atomized water can be evenly sprayed into each germination box 6. The water mist entering the germination box 6 will be absorbed by the absorbent cotton 8. The absorbent cotton 8 contacts the pepper seeds through the gauze 10 at its top, providing a moist environment for the seeds to promote seed germination. Multiple leakage grooves 7 are equidistantly arranged on the bottom wall of the germination box 6, which can prevent water accumulation, ensure the appropriate humidity around the seeds, and avoid seed rot caused by excessive moisture. The hooks 9 fixedly arranged on the front and rear sides of the inner wall of the germination box 6 cooperate with the hanging holes 11 at the four corners of the gauze 10, facilitating the fixing and replacement of the gauze 10, ensuring that the gauze 10 can stably cover the absorbent cotton 8 during use, providing good moisture retention and ventilation conditions for the seeds;

[0042] Moreover, by starting the water pump 202, the water in the water tank 201 is pumped out. The pumped water enters the output pipe 203 connected to the top of the water pump 202. Subsequently, the water flow moves forward along the output pipe 203. When the water flow reaches a plurality of shunt pipes 204 connected equidistantly on the front side of the output pipe 203, the water flow is shunted into each shunt pipe 204. A plurality of branch pipes 205 are connected to the left and right sides of each shunt pipe 204, and the water is further distributed into these branch pipes 205. Finally, the water is sprayed out from a plurality of atomizing nozzles 206 connected to the bottom wall of the branch pipes 205 to form fine water mist. These atomizing nozzles 206 are evenly distributed in the germination accelerating box 3, which can ensure that the water mist is evenly sprayed into each germination accelerating box 6, providing sufficient and uniform moisture for the pepper seeds. The water circulation component arranged on the bottom wall of the germination accelerating box 3 can collect and process the excess water, enabling it to return to the water tank 201 again for recycling, improving the utilization rate of water resources and also ensuring the humidity stability of the germination accelerating environment.
