[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] like Figures 1-5 As shown, this specific embodiment adopts the following technical solution: It includes:
[0029] The culture dish 1 is a hollow cylindrical structure with an opening at the top. A water channel 2 is provided on the inner bottom surface of the culture dish 1, and an absorbent sponge 3 is placed in the water channel 2. The absorbent sponge 3 absorbs water to maintain the humidity of the inner bottom surface of the culture dish 1.
[0030] Sponge plate 4, which is circular in structure, is placed inside the petri dish 1 and is located above the absorbent sponge 3, so that the water in the absorbent sponge 3 can be absorbed onto the sponge plate 4.
[0031] The limiting ring 5 is fixedly installed on the inner wall of the culture dish 1 and is located above the sponge plate 4. The limiting ring 5 plays a limiting role.
[0032] The grid plate 6 is movably disposed inside the petri dish 1, and the grid plate 6 is set in contact with the limiting ring 5. The grid plate 6 separates the seeds from the water, making it easier for the seeds to germinate on the grid plate 6.
[0033] A water storage ring 7 is fixedly installed on the ring wall of the petri dish 1, and a water storage tank 8 is provided inside the water storage ring 7. The water storage tank 8 is connected to the water passage tank 2. A water inlet pipe 9 is provided through the water storage ring 7. The water storage ring 7 serves to store water. Together with the water-absorbing sponge 3 and the sponge plate 4, it ensures the humidity inside the petri dish 1. A water-blocking plate 18 is provided on the opening on the inner wall of the water storage ring 7. The water-blocking plate 18 is set in contact with the water-absorbing sponge 3. The water-blocking plate 18 is made of sponge to limit the amount of water flowing out of the opening inside the water storage ring 7. A thermostat 19 is provided on the ring wall of the water storage ring 7. The heating end of the thermostat 19 is located inside the water storage ring 7 to control the temperature of the water inside the water storage ring 7.
[0034] A limiting component 10 is disposed within the culture dish 1 and engages with the grid disk 6 in contact with it. The limiting component 10 comprises:
[0035] The limiting cylinder 11 is a hollow cylindrical structure with openings at both the top and bottom. The limiting cylinder 11 is movably inserted into the culture dish 1, and the ring wall of the limiting cylinder 11 is in contact with the inner wall of the culture dish 1. The bottom end of the limiting cylinder 11 is in contact with the grid disk 6. Inserting the limiting cylinder 11 into the culture dish 1 makes it easier to fix the grid disk 6 on the limiting ring 5. The bottom end of the limiting cylinder 11 is provided with a contact pad 15, which is in contact with the grid disk 6 to protect the grid disk 6 to a certain extent.
[0036] The retaining ring 12 is fixedly installed on the ring wall at the top of the limiting cylinder 11, and the retaining groove on the retaining ring 12 is movably engaged with the culture dish 1. The retaining ring 12 restricts the top of the limiting cylinder 11, making it easy to fix the limiting cylinder 11 inside the culture dish 1. Several pressing plates 16 are provided at equal angles on the ring wall of the retaining ring 12. The pressing plates 16 are provided with pressing pads 17, which makes it easy for the operator to apply stress on the pressing plates 16, thereby installing the limiting cylinder 11 inside the culture dish 1.
[0037] Connecting piece 13, there are several connecting pieces 13, which are fixed at equal angles on the ring wall of the retaining ring 12. After the fixing screw 14 passes through the side wall of the connecting piece 13, it is screwed onto the ring wall of the culture dish 1. The fixing screw 14 makes it easy to fix the limiting cylinder 11 inside the culture dish 1.
[0038] When using this invention, the operator first places the absorbent sponge 3 in the water channel 2, ensuring it contacts the water-blocking plate 18. Then, the sponge plate 4 is placed on top of the absorbent sponge 3. Water is then used to moisten the absorbent sponge 3 and the sponge plate 4 to ensure humidity within the culture dish 1. Water is then poured into the water storage ring 7 through the water inlet pipe 9. The water absorption by the water-blocking plate 18, the absorbent sponge 3, and the sponge plate 4 ensures humidity within the culture dish 1. Finally, the grid plate 6 is installed on the limiting ring 5, allowing the grid plate to... 6. Contact the sponge plate 4, and then insert the limiting cylinder 11 into the culture dish 1, so that the contact pad 15 contacts the grid plate 6. At this time, the retaining ring 12 is movably locked on the ring wall of the culture dish 1. The operator applies stress on the pressing plate 16, moves the connecting piece 13 to the appropriate position, and then connects the connecting piece 13 to the culture dish 1 through the fixing screw 14, thereby fixing the limiting cylinder 11 to the culture dish 1. Finally, the operator places the seeds on the grid plate 6 and seals the culture dish 1 in the incubator.
[0039] Compared with the prior art, the beneficial effects of this utility model are:
[0040] 1. By utilizing the water storage function of the water storage ring 7, and in conjunction with the water absorption function of the water-absorbing sponge 3 and the sponge plate 4, the humidity in the petri dish 1 is ensured, so that the seeds are always in a suitable environment and the germination of wheat seeds is guaranteed.
[0041] 2. Set a limiting component 10, which restricts the grid disk 6 within the culture dish 1 through the limiting cylinder 11, and then fixes the limiting cylinder 11 within the culture dish 1 through the fixing screw 14 and the connecting piece 13, so as to fix the position of the grid disk 6.
[0042] 3. Set up a contact pad 15 to protect the mesh disk 6 to a certain extent and prevent the mesh disk 6 from bending under force;
[0043] 4. A thermostat 19 is installed to control the temperature of the water in the water storage ring 7, ensuring that the seeds are in a suitable environment for germination.
