Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Examples

In a specific embodiment, as shown in fig. 1 and 2, a plasma disinfection, sterilization and preservation cabinet comprises a main body 1, a cabinet door 2, a refrigeration compressor 3, a partition frame 4, a fan coil 5 and a plasma generation module 6; the cabinet door 2 is arranged on the front side of the main body 1, the refrigeration compressor 3 is arranged at the bottom of the main body 1, the fan coil 5 is arranged at the top of the main body 1, and the plasma module generation module 6 is arranged inside the main body 1.

In this embodiment, the main body 1 is provided with the fresh-keeping cabinet door 2 on the front, and the main body 1 is provided with the refrigeration compressor 3 at the bottom. A plurality of partition racks 4 are arranged in the main body 1, and a fan coil 5 is arranged at the top of the inside of the main body 1. The plurality of plasma generation modules 6 may be installed at any position in the main body 1, for example, the plasma generation modules 6 may be installed at the top fan air outlet, the side wall, etc. of the main body 1. The inside air current of main part 1 gets into fan coil 5 from the wind inlet under the effect of fan, takes place the heat exchange with the inside surface cooler of fan coil 5 simultaneously, spouts from the air outlet after the cooling, and the air in the fresh-keeping cabinet passes through fan coil 5 at 1 internal cycle of main part. Install the plasma generation module 6 inside main part 1 and directly release the positive and negative ion of harmless high concentration in to the fresh-keeping cabinet 1, plasma inactivation district at the inside high concentration that forms of fresh-keeping cabinet 1, positive and negative ion spreads whole main part 1 inner space along with the flow of inside air, can kill the germ that the air carried in main part 1, the germ on object surface, play and restrain bacterial growth in the cabinet, the surface of disinfectant body, prevent the effect of biofilm's formation, the shelf life of object in main part 1 has effectively been prolonged, and the phenomenon such as secondary pollution that main part 1 inside mould led to the fact has been stopped. Meanwhile, high-concentration positive and negative ions pass through the fan coil 5 along with airflow and contact with the fan coil 5 to inhibit the formation and growth of mold at the fan coil 5.

In a preferred embodiment, as shown in fig. 3 and 4, the plasma generation module 6 includes a plasma generation unit 6-1 provided with an ion discharger 6-2.

When the plasma generator is used, the distance between the plasma generating units is 40mm to 1500mm, the equipment utilizes the energy released by the combination of positive and negative ions to sterilize, and if the distance between the plasma generating units is too far, the concentration of the positive and negative ions cannot achieve the effective sterilization effect or the sterilization effect is not obvious. However, if the distance between the plasma generating units is too close, the positive and negative ions are compounded in a short time after being released, and cannot move to each position of the main body 1 sufficiently, so that the comprehensive disinfection and sterilization effect is achieved.

In a preferred embodiment, the ion releaser is a micro-nano fiber cluster.

In this embodiment, the ion releaser adopts micro-nano fiber clusters, the diameters of the micro-nano fibers are different from 10 nanometers to 100 micrometers, the number of the micro-nano fibers on each micro-nano conductive fiber cluster is different from 1000 plus 100000, that is, the ion releaser with different numbers of 1000 plus 100000 generates ions with efficiency far higher than that of a single needle point electrode or a DBD plate electrode under the same voltage. The ion releaser adopting the micro-nano fiber cluster can generate a large amount of positive and negative ions, so that the ion concentration of disinfection can be easily achieved, the objects in the main body 1 can be disinfected and sterilized efficiently, a large amount of energy consumption can not be generated, or any bad effect can be generated in the process of disinfection and sterilization of the main body 1. And the nano fiber cluster is used as an ion releaser, high-concentration plasma can be generated under low voltage, and the problem that harmful byproducts such as ozone, ultraviolet rays and nitric oxide are generated or chemical substances are used to cause loss in disinfection and sterilization in the prior art is solved.

In a preferred embodiment, the ion releasers are distributed on the plasma generating unit in a row brush shape.

In a preferred embodiment, the plasma generating units 6-1 are in a relatively parallel arrangement.

In a preferred embodiment, the plasma generator further comprises a power supply, and the power supply is connected with the plasma generation module 6.

In the present embodiment, a separate power supply is provided, and the power supply is directly connected to the plasma generation module 6. The positive ion plasma generating unit 6-3 and the negative ion plasma generating unit 6-4 are respectively connected with the positive electrode and the negative electrode of the power supply, so that the plasma generating module 6 is ensured to continuously and stably release high-concentration positive and negative ions, and the positive and negative ions in the main body 1 are ensured to be always kept at a relatively high level, thereby realizing effective disinfection and sterilization for the interior of the main body 1.

In a preferred embodiment, the power supply is a high voltage constant current power supply.

In this embodiment, the power belongs to constant current power supply, the disinfection of disinfecting through releasing positive and negative ion to main part 1 inside is taken place to the plasma, the ion release ware that micro-nano conductive fiber cluster is constituteed discharges through the fibre of big excess, can guarantee sufficient discharge channel, make power work in the constant current mode, thereby keep the stability of ion concentration, realize releasing high concentration's plasma steadily under the corona discharge threshold value, the possibility of the too high harmful accessory substance of production of voltage has been stopped, the bacterium is disinfected and is protected environmental safety more. The situation that the generating concentration of positive and negative ions is unstable can not occur, and the sterilization and disinfection effects are further influenced.

It should be understood that the above description is only exemplary of the present invention, and is not intended to limit the present invention, and that any modifications, equivalents, improvements, etc. made within the spirit and principle of the present invention should be included within the scope of the present invention.
