An activated carbon filter chamber 10 is opened inside the housing 3. An activated carbon filter block 11 is movably connected inside the activated carbon filter chamber 10. A baffle 12 is fixedly connected to the side of the activated carbon filter block 11. Threaded holes 14 are opened on the side of the baffle 12 and the side of the housing 3. A bolt 13 is threadedly connected inside the threaded holes 14. An air outlet 15 is opened on the side of the housing 3. An ultraviolet germicidal lamp 16 is fixedly connected to the side of the housing 3. A timer 17 is fixedly connected to the upper surface of the housing 3.

[0025] By adopting the above technical solution, for the anti-odor and sterilization device for a refrigerator, with the cooperation of the exhaust fan 8, the activated carbon filter block 11, the ultraviolet germicidal lamp 16, the timer 17 and the ozone generator 26, when people need to perform anti-odor and sterilization on the inside of the refrigerator main body 1, with the cooperation of the exhaust fan 8, the activated carbon filter block 11, the ultraviolet germicidal lamp 16 and the timer 17, the exhaust fan 8 operates, thereby driving the air inside the refrigerator main body 1 to flow through the activated carbon filter chamber 10, and the internal activated carbon filter block 11 filters the odor, thus facilitating the purification of the air inside the refrigerator main body 1. At the same time, with the cooperation of the ultraviolet germicidal lamp 16, the function of anti-odor and sterilization on the inside of the refrigerator main body 1 is realized.

[0026] Specifically, a sliding groove 18 is fixedly connected inside the refrigerator main body 1, and a placement plate 19 is movably connected inside the sliding groove 18.

[0027] Specifically, a hinge 20 is fixedly connected to the side of the refrigerator main body 1, a second movable door 21 is fixedly connected to the side of the hinge 20, and a handle 22 is fixedly connected to the side of the second movable door 21.

[0028] By adopting the above technical solution, for the anti-odor and sterilization device for a refrigerator, by setting the baffle 12, the bolt 13 and the threaded holes 14, when people need to replace the activated carbon filter block 11, by turning the bolt 13, the activated carbon filter block 11 is separated from the housing 3, thus facilitating people to replace the activated carbon filter block 11 and improving the practicability of the device.

[0029] Specifically, a wheel set 23 is fixedly connected to the lower surface of the refrigerator body 1. A brake pad 24 is arranged on the side of the wheel set 23. There are four wheel sets 23 in total, and they are arranged in a rectangle at the lower end of the refrigerator body 1.

[0030] Specifically, a control switch 25 is fixedly connected to the side of the refrigerator body 1.

[0031] The working principle of the present utility model is as follows: When in use, first insert the clamping block 4 into the clamping groove 5 for clamping and fixing.

When people need to prevent odor and sterilize the inside of the refrigerator body 1, start the operation of the exhaust fan 8 through the control switch. With the cooperation of the exhaust fan 8, the activated carbon filter block 11, the ultraviolet germicidal lamp 16, the timer 17, and the ozone generator 26, the air inside the refrigerator body 1 is extracted by the exhaust fan 8. After filtering out small particle impurities through the mesh cover 9, the air is sent into the activated carbon filter chamber 10, adsorbed and deodorized by the activated carbon filter block 11, and then sent out through the air outlet 15 together with the ozone generated by the ozone generator, thereby achieving the purpose of preventing odor and sterilization. Since food is extremely susceptible to Listeria, the ozone generated by the ozone generator can effectively kill bacteria such as Listeria, Escherichia coli, and Staphylococcus aureus existing in the refrigerator. And ozone has a strong oxidation effect, which can damage the DNA and RNA of bacteria to achieve the purpose of sterilization. Then, through the irradiation of the ultraviolet germicidal lamp 16, the DNA structure of microorganisms inside the refrigerator is further damaged, making them lose the function of reproduction and self-replication, thus achieving the purpose of sterilization and disinfection. The timer 17 arranged on the upper surface of the outer shell 3 can set the on-off time of the ultraviolet germicidal lamp 16 and the exhaust fan 8, and can perform timed sterilization according to the needs of the user. After the inside of the refrigerator is deodorized and sterilized by the ultraviolet germicidal lamp 16 and the activated carbon filter block 11 inside the activated carbon filter chamber 10, the inside of the refrigerator reaches the effect of no odor and extended food freshness.

[0032] This specific embodiment is only an explanation of the present utility model, and it is not a limitation to the present utility model. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
