DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

Embodiment 1

[0019] As shown in FIGS. 1 and 2, a container for the dry fog humidity control and freshness preservation of fruits and vegetables according to an exemplary embodiment of the present disclosure comprises a container body 1 and a refrigeration unit, wherein the refrigeration unit comprises a compressor, an evaporator 2 and a condenser (the compressor and the condenser are not shown in the figures). The evaporator 2 is located inside the container body 1, and cold air is blown into the container body through an air blower. The condensed water of the refrigeration unit is collected by a water tank 3.

[0020] A dry fog atomization spray head 8 is disposed adjacent to the evaporator 2 in the container body 1, and comprises a gas cavity 8-4, a liquid cavity 8-2, a mixing cavity 8-5 and a nozzle 8-6. A liquid inlet 8-1 of the liquid cavity 8-2 is in communication with the water tank 3 through a first conduit 5, and a water pump is provided in the water tank 3 and used to supply water to the dry fog atomization spray head 8. A gas inlet 8-3 of the gas cavity 8-4 is connected with an air compressor. The nozzle 8-6 of the dry fog atomization spray head 8 faces the evaporator 2 so as to enable dry fog generated by the dry fog atomization spray head 8 to be discharged along with cold air of the refrigeration unit and diffused to the entire container body 1 quickly.

[0021] The present embodiment may also make the following improvements.

[0022] 1) A humidity sensor is disposed in the container body 1. The humidity sensor can be connected with a controller, and the humidity in the container can be automatically and precisely controlled and adjusted, so that the container always has uniform moisture, to ensure the fruits and vegetables fresh-keeping effect.

[0023] 2) A filter device is disposed at a water inlet of the water tank 3. The filter device is used to filter out impurities in the condensed water, thereby preventing the dry fog atomization spray head from clogging.

[0024] 3) An overflow pipe is disposed on the water tank 3.

[0025] 4) The container body 1 is divided into a first container body and a second container body by a partition 6, the evaporator 2 and the dry fog atomization spray head 8 are disposed in the first container body, the evaporator 2 is slantwise arranged from top to bottom, a water collecting sump 7 is disposed at the bottom of the first container body and in communication with the water tank 3 through a second conduit 4, an air supply guiding plate (not shown in the figures) is provided on the first container body, and cold air generated by the refrigeration unit enters the second container body through the air supply guiding plate.

Embodiment 2

[0026] Embodiment 2 is an improvement over embodiment 1, and the difference is, as shown in FIG. 3, a negative ion generating apparatus. The negative ion generating apparatus comprises a DC negative high-voltage generator (not shown in the figures) and a negative ion releasing tip 9, and the negative ion releasing tip 9 is disposed in the gas cavity 8-4 and adjacent to the mixing cavity 8-5.
