Example 1

[0023] like Figures 1 to 4 As shown, this utility model provides a car refrigerator with plasma sterilization function, including a cabinet 1, a storage cavity 2 inside the cabinet 1, and a door 3 on the outside of the storage cavity 2, with one side of the door 3 hinged to the cabinet 1; specifically, a storage box 4 is provided inside the storage cavity 2, the storage box 4 includes an upper storage box 41 and a lower storage box 42, both the upper storage box 41 and the lower storage box 42 are provided with through holes 5 and plasma sterilization components 10 that cooperate with the through holes 5.

[0024] When the door 3 is closed, the plasma sterilization component 10 starts working; when the door 3 is opened, the plasma sterilization component 10 stops working. A control unit is located inside the enclosure 1. Specifically, the control unit includes a control circuit board. The door 3 and the plasma sterilization component 10 are electrically connected to the control circuit board. An illumination lamp is also located on the inner wall of the enclosure 1, and the illumination lamp is also electrically connected to the control circuit board. Specifically, when the door 3 is opened, due to the electrical connection between the door 3 and the control circuit board, the door 3 transmits a current signal to the control circuit board. The control circuit board then transmits the current signal to both the plasma sterilization component 10 and the illumination lamp, thereby controlling the plasma sterilization component 10 to start working and the illumination lamp to illuminate. Conversely, when the door 3 is closed, the door 3, through the control circuit board, controls the plasma sterilization component 10 and the illumination lamp to stop working simultaneously.

[0025] The cabinet door 3 and the lighting lamp are electrically connected to the control circuit board via wires. The plasma sterilization component 10 can also be electrically connected to the control circuit board via wires or by directly integrating it onto the control circuit board.

[0026] The plasma sterilization component 10 is a highly efficient disinfection device. Its working principle is mainly based on the generation of plasma and its inactivation effect on microorganisms. Plasma is an ionized gaseous substance composed of positive and negative ions generated after atoms and atomic groups have lost some electrons and are ionized. It has high conductivity and good fluidity. When a high-voltage electric field acts on the gas, the gas molecules are ionized, forming electrons, positive ions, and negative ions. These charged particles move at high speed under the influence of the electric field, forming plasma. The specific mechanism of plasma sterilization is as follows: the high-energy electrons and active particles in the plasma can interact with the cell walls of microorganisms, destroying their cell structure, thereby achieving the purpose of disinfection; the active oxygen in the plasma (such as ozone) has strong oxidizing properties, which can oxidize the proteins, nucleic acids, and other macromolecules of microorganisms, thereby killing them; some plasma sterilization devices also utilize ultraviolet light to penetrate deep into the interior of microorganisms, destroying their nucleic acid structure and rendering them infective.

[0027] The plasma sterilization component 10 includes a box body 6, a cover body 7, and a plasma generator 8 for releasing sterilizing gas; specifically, the box body 6 has an installation cavity 61 for installing the plasma generator 8, the cover body 7 is hooked to the box body 6, the box body 6 is snapped onto the through hole 5, and the installation cavity 61 is arranged outside the storage box 4.

[0028] The cover 7 is provided with a hook 71, and the box 6 is provided with a hook hole 62 that cooperates with the hook 71.

[0029] The plasma generator 8 is provided with a mounting hole 81, and the mounting cavity 61 is provided with a mounting post 63 that mates with the mounting hole 81.

[0030] The storage box 4 contains a storage area 9, and the mounting cavity 61 is connected to the storage area 9. The cover 7 is provided with a gas flow hole 72 for the flow of sterilizing gas.

[0031] The working principle of this embodiment is as follows: when the door 3 is closed, the plasma generator 8 emits sterilizing gas, which enters the storage area 9 of the storage box 4 through the gas flow hole 725 on the cover 7 to sterilize and disinfect the items in the storage area 9; when the door 3 is opened, the plasma generator 8 stops working to save energy.

[0032] The advantages of this utility model are: simple structure, sterilization and disinfection of items in storage area 9 by plasma sterilization component 10, ensuring food safety for users; plasma sterilization component 10 starts and stops working in conjunction with opening and closing of cabinet door 3, saving energy and being environmentally friendly, and plasma sterilization component 10 is easy to install, improving assembly efficiency. Example 2

[0033] like Figure 5 As shown, unlike Embodiment 1, this embodiment has a pull-out cup holder assembly on the side of the box. The cup holder assembly includes a cup holder body 11, with first tracks on both sides of the cup holder body 11. A second track that cooperates with the first tracks is provided inside the box 1. At least one retractable cup holder support 12 is provided on the cup holder body 11. The cup holder support 12 is made of flexible material. Other structures are the same as in Embodiment 1.

[0034] The working principle of this embodiment is as follows: the user can pull the cup holder body 11 outward by the cooperation of the first track and the second track, and place the cup on the cup holder tray 12. Because the cup holder tray 12 is made of flexible material, the cup holder tray 12 extends downward under the action of the weight of the cup and supports the cup. When not in use, the user takes out the cup, supports the bottom of the cup holder tray 12 and retracts it upward until the bottom of the cup holder tray 12 is flush with the bottom of the cup holder body 11, and finally pushes the cup holder body 11 inward to retract it into the box.
