Technical Field
[0001] The utility model relates to the technical field of agricultural seedling cultivation, in particular to a far-infrared seedling cultivation heating pad. Background Art
[0002] When planting vegetables, fruits and melons, it is necessary to cultivate the vegetable and fruit seedlings and then cultivate them to improve the survival rate of vegetable planting.
[0003] When winter comes, keeping warm in the greenhouse is one of the important tasks for growing vegetable seedlings in winter. However, as the insulation time of the greenhouse increases, the ventilation conditions in the greenhouse deteriorate, which can easily cause an increase in humidity in the greenhouse, making the vegetable seedlings susceptible to diseases such as damping-off and wilt, resulting in seedling death.
[0004] At present, in order to solve the problem of increased humidity in the greenhouse during seedling heat preservation, the main method is to heat the seedlings to achieve the effect of heat preservation and dehumidification. Most of the existing heating materials are electric heating wire products, which meet the heating needs by heat conduction. However, plants cannot adapt to the dryness and heat caused by electric heating wire heating, and it will cause burnt edges.
[0005] Therefore, there is an urgent need to improve the existing technology and design a new seedling heating type to solve the above-mentioned difficulties and pain points of the existing technology. Utility Model Content

[0010] Furthermore, the self-supporting carbon nanotube film is adhered and connected to the upper surface of the copper foil in an interval arrangement, and the contact between the self-supporting carbon nanotube film and the copper foil is coated with conductive silver paste; electrode wires are adhered and connected to the surface of the copper foil, and the connection between the electrode wires and the copper foil is coated with UV glue, which protects the electrode wires; the electrode wires are electrically connected to the corresponding polarity of the signal input terminal of the controller.
[0011] Carbon nanotube film is a two-dimensional planar structural material composed of orderly arranged carbon nanotubes. It is the most conductive flexible self-supporting film material known so far. It also has the advantages of being light and flexible, and having strong environmental weather resistance. It has multiple functional properties such as heating and infrared therapy.
[0012] Furthermore, the controller is provided with a humidity display screen, a temperature display screen, a heating button, a cooling button, and a controller switch.

[0016] Furthermore, the outer protective layer is made of PVC waterproof fabric.
[0017] PVC fabric is light, waterproof, moisture-proof and flame-retardant, which can protect the heating unit layer and provide waterproof effect.
[0018] Preferably, the PVC fabric is laminated with the TPU hot melt adhesive film and the heating unit layer by a hot press at 130° C. for 20 seconds. The resulting heating pad is required to have a flat surface, no damage, and no bubbles, and the production of the heating pad part is finally completed.
[0019] Furthermore, the power input terminal of the controller is connected to a power plug via a power wire. Preferably, the power plug is a three-phase power plug.
[0020] Furthermore, the probe positioning plate is provided with a plurality of positioning holes, through which the temperature probe and the humidity probe are fixedly connected, and the positioning holes play a role in controlling the probe spacing and insertion depth.
[0021] Furthermore, the number of the positioning holes is 18-30.

[0025] Compared with the prior art, the beneficial effects of the utility model are:
[0026] The far-infrared seedling heating pad provided by the utility model has a simple and reasonable structure and strong integrity. It takes the carbon nanotube film as the heating core. The far-infrared rays released by the carbon nanotube film penetrate into the plant tissue in the form of thermal radiation, promote the "resonance" of molecules and atoms inside the tissue to generate heat energy, and increase the temperature of the deep tissue. Not only is there no burning sensation during the entire heating process, but uniform heating can also be achieved, making the heating process more comprehensive and uniform, which is helpful for the dehumidification process of seedling cultivation and improves the dehumidification and heat preservation efficiency of seedling cultivation in winter. In addition, far-infrared heating promotes the photosynthesis of seedlings, improves the metabolic efficiency of seedlings, and improves the disease and insect resistance of seedlings, thereby promoting the growth and development of seedlings, accelerating the final maturity of plant fruits, and improving the earlyness and consistency of plants.
