Description

Multifunctional lunch box that can be sterilized

technical field

The utility model relates to a multifunctional lunch box, in particular to a multifunctional lunch box with sterilization and disinfection functions.

Background technique

Lunch boxes are one of the necessities in people's lives, and many office workers carry meals and fruits through lunch boxes. In addition, when many people have a picnic, they also like to carry meals and cleaned vegetables and fruits in the dining box. However, in the process of food storage, a lot of bacteria will continue to grow, burying hidden dangers to human health.

Numerous studies have shown that ultraviolet light can effectively eliminate various harmful bacteria, and is an effective and green sterilization method. The traditional ultraviolet light source is a mercury lamp, which has a large volume and mercury will cause harm to the environment. Because AlGaN-based UV LEDs have the advantages of energy saving, environmental protection, and small size, they are gradually replacing traditional UV lamps in some application fields of sterilization and disinfection. For example, some new UV LED-based sterilization and disinfection products have appeared on the market, such as UV LED disinfection cabinets, UV LED sterilization toothbrush boxes, UV LED sterilization milk bottles, UV LED water cups and so on.

Utility model content

The purpose of this utility model is to propose a multi-functional lunch box, which not only has the function of a conventional lunch box, but also has the function of sterilization and disinfection.

The utility model provides a sterilizable multifunctional lunch box, which is characterized in that it comprises:

A box body, the box body is a double-layer structure of the tank body;

A box cover, which is fastened on the top of the box body, and the box cover has a double-layer structure;

A power supply, which is installed inside the double-layer structure of the box body or inside the double-layer structure of the box cover; the power supply is a wired charging power supply or a wireless charging power supply;

An ultraviolet LED lamp, which is installed inside the double-layer structure of the box body or inside the double-layer structure of the box cover, and is connected to the power supply;

A switch, which is installed on the outside of the box body or the outside of the double-layer structure of the box cover, is connected with the ultraviolet LED lamp and a power supply, and controls the switch of the ultraviolet LED lamp.

The beneficial effect of the utility model is that the ultraviolet LED can emit sterilizing ultraviolet light when electrified to sterilize the food in the lunch box.

Detailed ways

Please refer to Fig. 2, the utility model provides a multifunctional lunch box, which is characterized in that it includes:

A box body 11, the box body 11 is a double-layer structure of the tank body;

A box cover 12, which is fastened on the top of the box body 11, and the box cover 12 is a double-layer structure;

The outer walls of the box body 11 and the lid 12 are completely opaque to prevent ultraviolet rays from leaking; the outer walls of the box body 11 and the lid 12 can also be partly transparent or completely transparent, and Partially coated with fluorescent powder, emits visible light under the excitation of ultraviolet light, and is used to monitor whether the ultraviolet LED lamp 122 is working normally. The item view of the sterilizable lunch box is circular, oval, heart-shaped, triangle, quadrilateral or other polygons.

A power supply 111, the power supply 111 is installed inside the double-layer structure of the box body 11 or inside the double-layer structure of the box cover 12. The power supply 111 can be a wired charging power supply or a wireless charging power supply (refer to FIG. 1 , which is a schematic diagram of the working principle of an electromagnetic induction wireless charging system). The basic working principle of wireless charging is: first convert the current into electromagnetic waves, and then convert the electromagnetic waves into current through the built-in chip receiver of the power supply to charge the power supply. When charging with wireless charging technology, there is no need for a charging cable to connect the standard power supply to the device power supply, and it is not necessary to remove the battery and put it into the charger for charging;

An ultraviolet LED lamp 112, which is installed inside the double-layer structure of the box body 11 or inside the double-layer structure of the box cover 12, is connected with the power supply 111; The ultraviolet LED lamp 112 can emit sterilizing ultraviolet light when powered on to sterilize the food in the lunch box. Among them, the ultraviolet LED lamp 112 is preferably an ultraviolet LED with a wavelength less than 300nm; in addition, preferably, the LED is made of III-V compound such as semiconductors such as AlGaN, and its core is a PN junction, so it has the I-V of a general PN junction. Characteristics, that is, forward conduction, reverse cut-off and even breakdown. What makes it different from general PN junctions is that under certain conditions, it also has luminous properties. Under forward voltage, electrons are injected from the N region into the P region, and holes are injected from the P region into the N region. Minority carriers entering the opposing region recombine with majority carriers to emit light. In addition, the ultraviolet LED has the function of sterilization and disinfection, that is, the light emitted by the ultraviolet LED when it is energized has the function of sterilization and disinfection;

A switch 113 is installed on the outside of the box body 11 , the switch 123 is connected with the UV LED lamp 112 and the power supply 111 to control the switch of the UV LED lamp 112 . The switch 113 can also be placed inside the box body 11, outside the double-layer structure of the lid 12 or inside the double-layer structure of the lid 12. The switch can be manually controlled, that is, the on and off of the switch It can be realized manually; the switch can also be a timer switch, that is, after closing the lunch box, press the switch once, and after the set time (such as one minute), it will automatically close;

The specific embodiments described above have further described the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above descriptions are only specific embodiments of the utility model and are not intended to limit the utility model. For new models, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
