Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A fruit and vegetable quick-freezing and fresh-keeping device comprises a cabinet 1, a refrigeration unit 2 is fixedly installed on the bottom wall of the cabinet 1, two connecting blocks 4 are slidably installed on the inner walls of both sides of the cabinet 1 through a connecting mechanism, the connecting mechanism comprises a connecting block 4 slidably installed inside a connecting frame 3, the connecting block 4 is provided with a fixing block 5, the fixing block 5 is fixedly installed on the outer wall of the connecting block 4, a placement box 6 is fixedly connected between two opposite connecting blocks 4, a leakage screen plate 7 is fixedly installed on the bottom walls of the two placement boxes 6 through an installation opening, a connection frame 8 is fixedly installed on the inner walls of both sides of the cabinet 1, and two connection frames are fixedly installed. Purification plates 9 are slidably installed inside the frame 8. Both purification plates 9 are made of activated carbon. Activated carbon is an active carbon material with very strong adsorption capacity. Its deodorizing principle is to guide the odorous gas to the surface of the activated carbon, and adsorb the odor molecules in the surface pores by chemical adsorption or physical adsorption, so as to achieve the effect of removing the odor. The outer walls of the two connecting frames 8 are slidably penetrated by fixing pins 10. The outer walls of the two purification plates 9 are provided with sockets that cooperate with the fixing pins 10, and the ends of the two fixing pins 10 are fixedly installed with shifting blocks 11.

[0023] The inner walls of the two shift blocks 11 are connected to the outer wall of the connecting frame 8 on the same side through a fixing mechanism. The fixing mechanism includes a fixing spring 12 installed on the outer wall of the fixing pin 10. The two ends of the fixing spring 12 are elastically connected to the outer wall of the connecting frame 8 and the inner wall of the shift block 11 respectively. The fixing spring 12 can fix the fixing pin 10 to prevent it from detaching from the outer wall of the connecting frame 8, thereby ensuring the fixing effect of the purification plate 9. A rotating tube 13 is rotatably installed inside the cabinet 1. A plurality of jet pipes 14 cooperating with the two placement boxes 6 are fixedly installed on the outer wall of the rotating tube 13. A plurality of jet holes connected to the interior are opened on the outer wall of each jet pipe 14. A circulating fan 15 is fixedly installed on the upper end surface of the cabinet 1. The end of the inlet pipe of the circulating fan 15 is fixedly connected to a circulating air duct 16 extending to the interior of the cabinet 1.

[0024] The outlet pipe of the circulating fan 15 is connected to the outer wall of the rotating tube 13 through a connecting mechanism, and the connecting mechanism includes a connecting sleeve 17 fixedly installed on the outer wall of the outlet pipe of the circulating fan 15, and the inner wall of the connecting sleeve 17 is rotatably connected to the outer wall of the rotating tube 13. A motor 19 is fixedly installed on the upper end surface of the cabinet 1 through a supporting mechanism, and the supporting mechanism includes a supporting plate 18 fixedly installed on the upper end surface of the cabinet 1, and the motor 19 is fixedly installed on the upper end surface of the supporting plate 18. The outer wall of the output shaft of the motor 19 is connected to the rotating tube 13 through a transmission mechanism, and the transmission mechanism includes a pulley 20 fixedly installed on the output shaft of the motor 19 and the outer wall of the rotating tube 13, and the two pulleys 20 are connected and transmitted by belts.

[0025] When the utility model is used, the cabinet 1 is a freezer in the prior art, which is equipped with a closed door, which is not indicated by a number in this scheme;

[0026] The specific working steps of this scheme are as follows: fruits and vegetables are placed inside the placement box 6, and the fruits and vegetables are placed on the upper end surface of the mesh plate 7. When the fruits and vegetables are quickly frozen and kept fresh, the refrigeration unit 2 can refrigerate the inside of the cabinet 1. At this time, the circulating fan 15 can extract cold air through the circulating air duct 16, and then discharge it to the inside of the rotating tube 13 through the cooperation of its outlet pipe. The cold air can flow from the inside of the rotating tube 13 to the inside of the jet pipe 14, and the cold air is then ejected from the inside of the jet pipe 14 through multiple jet holes. The ejected cold air can blow on the outer bottom wall of the placement box 6, and cool the fruits and vegetables at the bottom through the mesh plate 7, thereby increasing the freezing time of the fruits and vegetables.

[0027] At the same time, the motor 19 can drive the rotating tube 13 to rotate through two pulleys 20 connected by belts, and the rotating tube 13 can drive the multiple jet tubes 14 to rotate. Through the rotation of the multiple jet tubes 14, the contact area between the cold air and the fruits and vegetables can be increased, thereby improving the freezing effect of the fruits and vegetables. When the cabinet 1 quickly preserves the fruits and vegetables, the two purification plates 9 can absorb and evolve the odors emitted by the fruits and vegetables, thereby preventing the residual odors inside the cabinet 1 from causing odor contamination to subsequent fruits and vegetables. When the purification plate 9 needs to be replaced, the dial block 11 can be moved to drive the fixing pin 10 to move out of the socket, thereby releasing the fixation of the purification plate 9, and then the purification plate 9 can be pulled out of the connecting frame 8 for replacement, thereby ensuring the absorption and purification of the odor inside the cabinet 1, and the connection block 4 can be slid out of the connection frame 3 to achieve convenient disassembly of the placement box 6, thereby facilitating its cleaning.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
