DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in conjunction with the drawings and specific embodiments.

[0031] Reference Figures 1 to 5 As shown in the figure: a seed germination promoting device, comprising: A cylindrical cabinet body 1, one side of the cabinet body 1 is provided with a closable door body 11; A rotating disc frame 2 is horizontally arranged inside the cabinet body 1, a plurality of trays 21 are arranged on the rotating disc frame 2 in the circumferential direction, and culture dishes 22 are placed in the trays 21; A rotating shaft 3 vertically penetrates the center of the rotating disc frame 2 and is fixedly connected with the rotating disc frame 2; A top plate 4 is fixed to the top end of the rotating shaft 3, and the top plate 4 is funnel-shaped with the large-diameter end downward; An annular backflow tank 5 is arranged on the inner side wall of the upper end of the cabinet body 1, the annular backflow tank 5 has a backflow opening 51 at the top corresponding to the lower end position of the top plate 4, and the bottom of the annular backflow tank 5 is communicated with a drain pipe 52 extending to the outside of the cabinet body 1; A first rotary motor 6 is arranged on the top of the cabinet body 1, the first rotary motor 6 is in transmission connection with the rotating shaft 3, and is used for driving the rotating shaft 3, the rotating disc frame 2 and the top plate 4 to rotate synchronously; An environment regulating unit, comprising a controller 71 arranged on the cabinet body 1, and a spraying unit 72, an illumination unit 73, a ventilation unit 74, a heating unit 75 and a sensor unit 76 arranged in the cabinet body 1 and electrically connected with the controller 71.

[0032] The traditional seed germination device is a static structure, and the culture dish 22 is placed in a fixed position, which leads to uneven distribution of internal temperature and humidity, light, and uneven seed germination rate. At the same time, excess water is easy to accumulate at the top of the cabinet 1, breed bacteria, and the condensed water will drip into the culture dish 22, affecting seed growth. The device rotates the turntable frame 2 to realize uniform light and humidity of the culture dish 22, solves the problem of uneven distribution of the traditional device environment, and realizes waste water diversion through the cooperation of the funnel-shaped top plate 4 and the annular reverse flow groove 5, avoiding water accumulation and breeding bacteria. In use, the door body 11 is opened to place the culture dish 22 containing seeds in the tray 21, and after the door body 11 is closed, the first rotating motor 6 is started by the controller 71, the first rotating motor 6 drives the rotating shaft 3, the turntable frame 2 and the top plate 4 to rotate synchronously and slowly, so that the culture dishes 22 on each tray 21 are evenly distributed in the internal space of the cabinet 1. The sensor unit 76 detects the temperature, humidity and light intensity in the cabinet 1 in real time and transmits the detection data to the controller 71. The controller 71 automatically controls the operation of the spraying unit 72, the lighting unit 73, the ventilation unit 74 and the heating unit 75 according to the preset seed germination environment parameters. The spraying unit 72, the lighting unit 73, the ventilation unit 74 and the heating unit 75 are all located above the turntable frame 2. When the spraying unit 72, the lighting unit 73 and the heating unit 75 are started, the turntable frame 2 rotates, driving the culture dishes 22 in the tray 21 to rotate slowly and synchronously, so that the spraying unit 72, the lighting unit 73 and the heating unit 75 have a more sufficient effect on the germination in the culture dishes 22: When the humidity is lower than the preset value, the spraying unit 72 starts to supplement water; when the temperature deviates from the preset range, the heating unit 75 or the ventilation unit 74 starts to adjust the temperature; when the light intensity is insufficient, the lighting unit 73 starts to supplement light.

[0033] While the turntable frame 2 rotates, the top plate 4 also rotates. Part of the excess water produced by spraying flows along the funnel-shaped surface of the top plate 4 to the edge, and the rotating force can speed up the water on the top plate 4 to be thrown into the reverse flow opening 51 of the annular flow guide groove. The water discharged into the flow guide groove is finally discharged outside the cabinet 1 through the drain pipe 52, avoiding the accumulation of excess water at the top of the cabinet 1.

[0034] Referring to Figure 6 As shown, the lower surface of the top plate 4 is provided with a plurality of arc-shaped plates 41 distributed equidistantly along the circumference thereof, the curvature of the arc-shaped plates 41 is adapted to the funnel-shaped curvature of the top plate 4, and the lower end of the arc-shaped plates 41 extends above the reverse flow opening 51 of the annular reverse flow groove 5.

[0035] When the device is running, the top plate 4 rotates synchronously with the rotating shaft 3, and the arc-shaped plate 41 rotates with the top plate 4. The water droplets generated by the spraying fall on the lower surface of the top plate 4, and then slide along the surface of the arc-shaped plate 41 under the action of gravity and rotational centrifugal force. The arc-shaped plate 41 plays a guiding role and accurately guides the water droplets into the backflow opening 51 of the annular backflow groove 5, avoiding the water droplets from splashing and falling into the culture dish 22 deviating from the flow path.

[0036] Referring to Figure 4 and Figure 7 , the circumference of the top plate 4 is provided with a first annular sliding block 42, and the inner side wall of the cabinet 1 is provided with a first annular sliding rail 43 corresponding to the first annular sliding block 42. The top plate 4 is stably rotated by the sliding cooperation of the first annular sliding block 42 and the first annular sliding rail 43.

[0037] When the first rotating motor 6 drives the rotating shaft 3 and the top plate 4 to rotate, the first annular sliding block 42 on the circumference of the top plate 4 slides synchronously along the first annular sliding rail 43 of the inner side wall of the cabinet 1. The first annular sliding rail 43 provides circumferential support and guidance for the first annular sliding block 42, limits the shaking and deviation of the top plate 4 in the radial direction, ensures that the top plate 4 always rotates coaxially, and maintains a stable relative position between the lower end of the top plate 4 and the backflow opening 51 of the annular backflow groove 5.

[0038] Referring to Figure 8 , the tray 21 is a concave structure, the inner wall of the tray 21 is provided with anti-skid protrusions 222, and the bottom of the tray 21 is provided with a plurality of evenly distributed drainage holes 211. The turntable frame 2 is provided with a clamping groove 25, and the tray 21 is detachably placed on the clamping groove 25.

[0039] The culture dish 22 is placed in the concave groove of the tray 21, and the anti-skid protrusions 222 on the inner wall increase the friction between the culture dish 22 and the inner wall of the tray 21. In combination with the limiting effect of the concave structure, the culture dish 22 is effectively prevented from sliding or toppling when the turntable frame 2 rotates or sprays. The excess water generated by the spraying flows into the tray 21 through the gap at the bottom of the culture dish 22, and then quickly drains out through the drainage holes 211 at the bottom of the tray 21, avoiding the accumulation of water in the tray 21 and causing the culture dish 22 to be soaked at the bottom. When it is necessary to clean or replace the tray 21, the tray 21 can be easily taken out of the clamping groove 25 of the turntable frame 2 by upwardly forcing.

[0040] Referring to Figure 4 and Figure 9 , the circumferential surface of the turntable frame 2 is provided with a second annular sliding block 23, and the inner side wall of the cabinet 1 is provided with a second annular sliding rail 24 corresponding to the second annular sliding block 23. The turntable frame 2 improves the rotation stability by the sliding cooperation of the second annular sliding block 23 and the second annular sliding rail 24.

[0041] When the first rotary motor 6 drives the rotating shaft 3 and the rotating disc holder 2 to rotate, the second annular sliding block 23 on the circumference of the rotating disc holder 2 slides along the second annular sliding rail 24 on the inner wall of the cabinet 1. The second annular sliding rail 24 limits the second annular sliding block 23 in the radial direction, limiting the radial displacement and shaking of the rotating disc holder 2 during rotation, so that the rotating disc holder 2 always rotates stably and horizontally, ensuring that the culture dishes 22 in the tray 21 will not be tilted due to shaking, and at the same time dispersing the radial stress of the rotating shaft 3, reducing the wear of the rotating shaft 3.

[0042] Referring to Figure 4 As shown in the drawings, the bottom of the cabinet 1 is provided with a water collecting funnel 12, which is arranged below the rotating disc holder 2. The bottom of the water collecting funnel 12 is provided with a horizontally arranged sewage pipe 13, one end of which extends out of the cabinet 1. A spiral shaft 131 is arranged in the sewage pipe 13, and the other end of the sewage pipe 13 is provided with a second rotary motor 132 electrically connected with the controller 71. The output shaft of the second rotary motor 132 is in transmission connection with one end of the spiral shaft 131, for driving the spiral shaft 131 to rotate to discharge the sediments in the pipe.

[0043] The water dripping from the water draining hole 211 of the tray 21 is collected in the water collecting funnel 12 under the action of gravity and flows along the inner wall of the funnel to the sewage pipe 13. The controller 71 can preset a sewage discharge period, and the second rotary motor 132 drives the spiral shaft 131 to rotate. The blades of the spiral shaft 131 push the accumulated water and sediments in the sewage pipe 13 to the outlet of the pipe, and then discharge them into the water collecting basin, realizing automatic sewage discharge. After the sewage discharge is completed, the controller 71 controls the second rotary motor 132 to stop running.

[0044] Referring to Figure 3 and Figure 5 As shown in the drawings, the spraying unit 72 includes a spraying pipe 721 fixed to the inner wall of the cabinet 1, which is located between the top plate 4 and the rotating disc holder 2. The spraying pipe 721 has multiple groups and is equally distributed along the circumference of the cabinet 1. A plurality of atomizing nozzles 722 are arranged on the spraying pipe 721 at intervals. Each group of spraying pipes 721 is connected in communication through an annular water pipe 724, and the annular water pipe 724 is provided with an electromagnetic valve 723 electrically connected with the controller 71.

[0045] Based on the humidity data fed back by the sensor unit 76, the controller 71 controls the solenoid valve 723 to open when the humidity is lower than the preset value. External water is then supplied through the ring water pipe 724 and the spray pipe 721 to each atomizing nozzle 722. The atomizing nozzle 722 atomizes the water into fine droplets and sprays them evenly into the interior of the cabinet 1. At the same time, the turntable 2 rotates, ensuring that the culture dishes 22 on each tray 21 receive the atomized water evenly, avoiding uneven wetting in certain areas. When the humidity reaches the preset value, the controller 71 controls the solenoid valve 723 to close, stopping the spraying.

[0046] Reference Figure 3 and Figure 5 As shown: The lighting unit 73 includes a strip LED light 731 fixed to the inner side wall of the cabinet 1. The strip LED light 731 is located above the spray pipe 721. The strip LED light 731 has multiple sets and is equidistantly distributed along the circumference of the cabinet 1. The illumination direction of the strip LED light 731 is towards the tray 21 area of ​​the turntable frame 2.

[0047] The controller 71 controls the strip LED lights 731 to start or stop based on preset lighting parameters and lighting data fed back by the sensor unit 76. The equally spaced strip LED lights 731 emit light simultaneously, and the light shines on the rotating turntable 2 from different angles, so that the petri dishes 22 in each tray 21 receive light evenly during rotation, avoiding the formation of shadow areas. The controller 71 can adjust the lighting duration according to the germination requirements of different seeds.

[0048] Reference Figure 3 and Figure 10 As shown: The ventilation unit 74 includes a ventilation opening 741 opened on the side wall of the cabinet 1, a fan 742 is provided inside the ventilation opening 741, and a dust filter 743 is provided on the outside of the ventilation opening 741.

[0049] The controller 71 controls the fan 742 to start based on air quality data fed back by the sensor unit 76 or a preset ventilation cycle. When the fan 742 is running, it draws fresh air from outside the cabinet 1 into the cabinet 1 after filtering it through the dust filter 743, while simultaneously expelling stale air from inside the cabinet 1, creating air convection and promoting air circulation within the cabinet 1 to maintain fresh air. The dust filter 743 effectively blocks external dust and particulate matter from entering, preventing contamination of the cultivation environment; the operating time and frequency of the fan 742 can be adjusted by the controller 71.

[0050] Reference Figure 1 As shown: the door 11 is made of transparent material, the door 11 is connected to the cabinet 1 by a hinge 111, and the door 11 is provided with a handle lock 112 for locking the door 11.

[0051] The door body 11 is made of high-transparency tempered glass, so that the user can directly observe the germination state of the seeds in the cabinet 1 without opening the door body 11, thereby avoiding the fluctuation of the environmental parameters caused by opening the door; the door body 11 can be reliably locked by the handle lock 112, so as to avoid accidental opening; when the culture dish 22 needs to be taken out or placed, the handle of the handle lock 112 is pressed to unlock the door body 11.

[0052] Referring to Figure 3 and Figure 5 It is shown that the heating unit 75 includes an electric heating wire 751 electrically connected with the controller 71, the electric heating wire 751 surrounds the cabinet 1 and is fixed to the inner side of the cabinet 1, and the electric heating wire 751 is located above the turntable frame 2.

[0053] When the temperature in the cabinet 1 is lower than the preset value, the controller 71 controls the electric heating wire 751 to generate heat by being powered on; a plurality of groups of electric heating wires 751 are simultaneously heated, heat is uniformly radiated to the internal space of the cabinet 1, and the air circulation of the ventilation unit 74 is matched, so that the temperature in the cabinet 1 quickly tends to be uniform; when the temperature reaches the preset value, the controller 71 controls the electric heating wire 751 to be powered off to stop heating; if an abnormal overheating condition occurs, a temperature fuse is fused to cut off the power supply of the electric heating wire 751, thereby avoiding the burning of the seeds. The power of the electric heating wire 751 is designed to be gentle, and the precise control of the controller 71 is matched, so that stable temperature control is realized.

[0054] Referring to Figure 3 and Figure 4 It is shown that the sensor unit 76 includes a temperature sensor 761, a humidity sensor 762 and an illumination sensor 763, the temperature sensor 761, the humidity sensor 762 and the illumination sensor 763 are fixed to the inner side wall of the cabinet 1, and the detection end faces the central area of the inside of the cabinet 1.
