The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a cold storage and preservation device for agricultural products, including a box body 1, an isolation frame provided on the inner side of the box body 1, a pull-out box 4 provided on the isolation frame, a handle 5 fixedly installed on the front side of the pull-out box 4, four casters 16 movably installed on the bottom outer wall of the box body 1, a refrigeration unit 17 embedded in one side of the box body 1, and a circulation structure installed on the box body 1 for driving the air inside the box body 1 to circulate, and a filter structure installed on the circulation structure for removing odors inside the box body 1.

[0024] Furthermore, the isolation frame includes vertical plates 2 and horizontal plates 3. There are two vertical plates 2, which are fixedly installed on the front and rear inner walls of the box 1. There are three horizontal plates 3, which are fixedly installed between the two vertical plates 2. The pull-out box 4 is placed on top of the horizontal plate 3.

[0025] Furthermore, an opening is provided on the front side of the box 1, and the front side of the pull-out box 4 extends through the opening to the outside of the box 1. A sealing groove is provided in the opening, and a sealing ring is provided in the sealing groove. The sealing ring contacts the outer wall of the pull-out box 4. During the process of taking out and putting in agricultural products, the opening can be opened and closed by one-quarter to avoid the opening being fully opened and closed, thus reducing the loss of cold air.

[0026] Furthermore, the circulation structure includes an air extractor 10, an air supply pipe 11, an air extraction pipe A12, and an air extraction pipe B15. The air extractor 10 is fixedly installed on the top outer wall of the housing 1. One end of the air supply pipe 11 is fixedly connected to the output end of the air extractor 10, and one end of the air extraction pipe A12 is fixedly connected to the input end of the air extractor 10. The other end of the air supply pipe 11 and one end of the air extraction pipe B15 both penetrate the top of the housing 1 and communicate with the interior of the housing 1.

[0027] Furthermore, the filtration structure includes an odor-removing box 13, a lid 14, and activated carbon. The odor-removing box 13 is fixedly installed on the top outer wall of the housing 1. The lid 14 is snapped onto the top of the odor-removing box 13. The activated carbon is placed inside the lid 14. The other end of the suction pipe A12 and the other end of the suction pipe B15 both penetrate the side wall of the odor-removing box 13 and communicate with the interior of the odor-removing box 13. When the vacuum pump 10 is started, the vacuum pump 10 draws air from inside the housing 1 through the suction pipe A12, the odor-removing box 13, and the suction pipe B15. As the air passes through the odor-removing box 13, the activated carbon in the odor-removing box 13 adsorbs the odors in the air, thus purifying the air. The purified air is then returned to the housing 1 through the vacuum pump 10 and the air supply pipe 11.

[0028] Furthermore, the outer walls of the exhaust fan 10, air supply pipe 11, exhaust pipe A12, deodorizing box 13, box cover 14, and exhaust pipe B15 are all covered with thermal insulation cotton.

[0029] Furthermore, both sides of the vertical plate 2 are provided with air vents A8, and both sides of the pull-out box 4 are provided with air vents B9. Air vents A8 and B9 are connected. When storing or retrieving agricultural products, the handle 5 is manually pulled forward. The handle 5 moves the pull-out box 4 forward, opening and closing the pull-out box 4. After the pull-out box 4 moves forward, the air vents B9 and A8 are staggered, which can prevent the interior of the box 1 from communicating with the outside, further reducing the loss of cold air, preventing the box from losing too much temperature, and reducing power consumption.

[0030] Furthermore, guide openings 7 are provided on both sides of the vertical plate 2, and limit bolts 6 are threadedly installed on both sides of the pull-out box 4, with one end of the limit bolts 6 extending to the inside of the guide openings 7.

[0031] Working principle: When the refrigeration unit 17 is turned on, it will cool the inside of the cabinet 1. The cold air will enter the inside of the pull-out box 4 through the cold air inlet B9 and the cold air inlet A8, cooling the inside of the pull-out box 4. When storing or retrieving agricultural products, manually pull the handle 5 forward. The handle 5 will move the pull-out box 4 forward, opening and closing the pull-out box 4. After the pull-out box 4 moves forward, the cold air inlet B9 and the cold air inlet A8 are staggered to prevent the cold air inside the cabinet 1 from escaping. By turning on the exhaust fan 10, the exhaust fan 10 will draw air from the inside of the cabinet 1 through the exhaust pipe A12, the deodorizing box 13, and the exhaust pipe B15. As the air passes through the deodorizing box 13, the activated carbon in the deodorizing box 13 will adsorb the odors in the air, purifying the air. The purified air will be returned to the cabinet 1 through the exhaust fan 10 and the air supply pipe 11.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
