Description

Technical Field

[0001] The utility model belongs to the technical field of fruit and vegetable fresh-keeping, and particularly relates to a fruit and vegetable ice-temperature fresh-keeping device. Background Technique

[0002] Fruit and vegetable fresh-keeping boxes are devices designed specifically to extend the freshness of fruits and vegetables. They usually have the functions of controlling temperature and humidity to simulate the natural growth environment of fruits and vegetables and slow down their metabolic processes. According to different technologies and application scenarios, fruit and vegetable fresh-keeping boxes can be divided into various types, including household type, commercial type, and industrial type. Modern fruit and vegetable fresh-keeping boxes adopt a variety of advanced technologies to improve the fresh-keeping effect and energy efficiency. For example, some fresh-keeping boxes adopt controlled atmosphere fresh-keeping technology to further extend the fresh-keeping period of fruits and vegetables by adjusting the concentrations of oxygen, carbon dioxide, and ethylene in the box. In addition, some fresh-keeping boxes are also equipped with intelligent control systems that can remotely monitor and adjust the working status of the fresh-keeping box to ensure that fruits and vegetables are always in the best fresh-keeping environment.

[0003] Currently, after fruits and vegetables are picked, fresh-keeping devices are needed to store and transport them. However, during the storage and transportation process, since fruits and vegetables cannot replenish water, they will wither. Based on this, a fruit and vegetable ice-temperature fresh-keeping device is proposed. Content of the Utility Model

[0023] Embodiment

[0024] As Figures 1 - 5As shown in the figure, a fresh-keeping device for fruits and vegetables at ice temperature includes a box body 1, a box door 2 is installed on the box body 1, a refrigerator 3 is installed on the inner bottom of the box body 1, heat dissipation holes are opened on both sides of the box body 1 at the position of the refrigerator 3, and it further includes: a filter plate 4 fixedly connected to the inner wall of the box body 1 and located on the top of the refrigerator 3, water is filled in the bottom space of the box body 1 located under the filter plate 4, and a partition plate 5 is fixedly connected to the top of the filter plate 4; a fresh-keeping plate 6 in the form of a filter screen is fixedly connected to the bottom of one side of the partition plate 5, the partition plate 5 is located on one side of the fresh-keeping plate 6 and a fresh-keeping frame 7 is fixedly connected to the top of the fresh-keeping plate 6, multiple partition plates are arranged on the fresh-keeping frame 7, and the bottom of the fresh-keeping frame 7 is in the form of a filter screen; a moisturizing mechanism fixedly connected to the filter plate 4, the output end of the moisturizing mechanism is located on the top of the fresh-keeping frame 7, a water-changing hole is opened at the bottom of one side of the box body 1 where the box door 2 is located, a water-changing plug 8 is installed on the water-changing hole, the fresh-keeping plate 6 and the fresh-keeping frame 7 are both fixedly connected to the inner wall of the box body 1, the partition plate 5 is fixedly connected to the inner wall of the box body 1, and the moisturizing mechanism includes a water pump 1201 fixedly connected to the top of the filter plate 4, a water suction pipe 1202 is fixedly connected to the input end of the water pump 1201, a drainage hose 1203 is fixedly connected to the output end of the water pump 1201, a water sprinkling pipe 1204 is fixedly connected to the end of the drainage hose 1203 away from the water pump 1201, water sprinkling holes 1205 are opened at the bottom of the water sprinkling pipe 1204, the water sprinkling pipe 1204 is arranged on the top of the fresh-keeping frame 7, the water suction pipe 1202 penetrates through the filter plate 4 and is fixedly connected to the filter plate 4, a fixing plate 9 is fixedly connected to the inner wall of the box body 1 at the top of the water sprinkling pipe 1204, a sliding groove 10 is opened on the fixing plate 9, dust-proof nets 11 are opened on both sides of the box body 1, and the dust-proof nets 11 are arranged between the fresh-keeping plate 6 and the fresh-keeping frame 7, and a ventilation mechanism is slidably connected in the sliding groove 10.

[0025] When in use, first open the box door 2 and add sufficient water into the box body 1 through the filter plate 4, then place the fruits and vegetables to be insured in the fresh-keeping plate 6 and the fresh-keeping frame 7, and then close the box door 2 and start the refrigerator 3 and the water pump 1201. When starting the refrigerator 3, set the refrigeration temperature of the refrigerator 3 for the water so that the water does not freeze. The operation of the water pump 1201 will suck the cold water refrigerated by the refrigerator 3 through the water suction pipe 1202. The cold water enters the water sprinkling pipe 1204 through the drainage hose 1203, and then is sprayed on the fruits and vegetables placed on the fresh-keeping frame 7 through the water sprinkling holes 1205. Then, after a part of the cold water is absorbed by the fruits and vegetables on the fresh-keeping frame 7, it falls on the fruits and vegetables on the fresh-keeping plate 6 through the fresh-keeping frame 7, and then re-enters the water in the box body 1 through the filter plate 4.

[0026] The operation of sprinkling water on the fruits and vegetables is realized, so that the fruits and vegetables stored in the fresh-keeping device can absorb water, preventing the fruits and vegetables from wilting due to lack of water during storage and transportation, and ensuring the quality and aesthetic degree of the fruits and vegetables.

[0027] Such as Figure 2 、Figure 3 and Figure 5 As shown in Figure 5 , the ventilation mechanism includes a motor 1301 fixedly connected to the inner wall of the box body 1. The output end of the motor 1301 is fixedly connected with a reciprocating lead screw 1302. A slider 1303 is connected to the reciprocating lead screw 1302 by a thread. The slider 1303 is slidably connected in the chute 10. A fan blade 1304 is fixedly connected to the end of the reciprocating lead screw 1302. An air extraction cylinder 1305 is fixedly connected to the inner wall of the box body 1. The reciprocating lead screw 1302 is rotatably connected to the air extraction cylinder 1305. A dust filter screen 1306 is fixedly connected to the air inlet end of the air extraction cylinder 1305. The fan blade 1304 is arranged in the air extraction cylinder 1305. The end of the reciprocating lead screw 1302 is rotatably connected to the dust filter screen 1306.

[0028] When in use, when the water pump 1201 is started, the motor 1301 is started at the same time. The operation of the motor 1301 will drive the slider 1303 to slide back and forth in the chute 10 through the reciprocating lead screw 1302, so that the water sprinkling pipe 1204 slides back and forth on the top of the fresh-keeping box 7, and the water sprinkling holes 1205 perform uniform water sprinkling operation on the fruits and vegetables placed in the fresh-keeping box 7. During this process, the operation of the reciprocating lead screw 1302 will drive the fan blade 1304 to rotate, so that the air extraction cylinder 1305 extracts the outside air, which enters the top of the fixing plate 9 after being filtered by the dust filter screen 1306, then enters the top of the fresh-keeping box 7 through the chute 10, then enters between the fresh-keeping box 7 and the fresh-keeping board 6 through the fresh-keeping box 7, and finally is discharged to the outside environment through the dust-proof net 11;

[0029] The air inside the fresh-keeping box is replaced, preventing the gas generated by the spoilage of some fruits and vegetables from affecting other healthy fruits and vegetables, and ensuring the quality of fruit and vegetable freshness.

[0030] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
