Problems solved by technology
However, the mercury lamp sterilization device has the following disadvantages when used: First, the vapor pressure of the traditional mercury lamp drops sharply with the drop of temperature, resulting in a large reduction in light intensity at low temperatures. Compared with normal temperature, its power attenuation reaches 65 -85%, therefore, not suitable for use in cold storage cabinets
Third, the mercury lamp is bulky, occupying valuable internal space of the storage cabinet, reducing the number of items stored

Embodiment Construction
[0027] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] The present invention proposes a sterilizing device that uses an ultraviolet light-emitting diode sterilizing unit for sterilization. Due to the use of ultraviolet light-emitting diodes, not only are there many types of sterilization and comprehensive sterilization, but also because the light-emitting diodes are small in size and low in energy consumption, it is convenient to realize the miniaturization of the sterilizing device. and low energy consumption. In addition, the sterilizing device is designed in the form of a drawable shelf, which is convenient for installation and use in storage cabinets that need to be sterilized, and can also be conveniently matched with the box to form a drawer-type sterilizing device, and the items to be sterilized can be placed in the drawer Antivirus inside. The st...

Abstract
The invention discloses a draw-out type sterilization device and a storage cabinet with the same. The draw-out type sterilization device comprises a frame; at least one layer of substrate and at least one layer of light-transmitting plate are disposed in the frame; a ultraviolet light emitting diode sterilization unit with a plurality of ultraviolet light emitting diodes, and a circuit board connected with the ultraviolet light emitting diode sterilization unit are disposed between the substrate and the light-transmitting plate. The sterilization device of the invention has a small volume, performs sterilization by ultraviolet light emitting diodes (UVLED), has high sterilization efficiency and low energy consumption.
Description
technical field [0001] The invention relates to the field of ultraviolet sterilization technology, in particular to a drawable sterilization device and a storage cabinet provided with the sterilization device. Background technique [0002] Storage cabinets such as refrigerators, freezers, and safes mainly use cooling and dehumidification to slow down and inhibit the growth of microorganisms in items stored in storage cabinets such as various foods and medicines, and play a role in keeping fresh. In order to improve the fresh-keeping performance of storage cabinets, some of the prior art adopts vacuum means to keep fresh in storage cabinets, but the vacuum compressor used for vacuuming consumes a lot of energy, which is not conducive to energy-saving use. Moreover, most viruses and bacteria do not need oxygen to reproduce, so vacuum itself cannot kill harmful microorganisms that have grown on the surface of food. Moreover, vacuum preservation leads to dehydration of food, wh...
