[0021] like Figure 1 As shown, a seafood preservation device utilizing a low-voltage electrostatic field includes a preservation box 10. A sealing door 11 is installed on the front of the preservation box 10, and a set of storage drawers 12 are provided inside the preservation box 10. A low-voltage electrostatic generator 13 is fixedly installed on the top of the preservation box 10, and a negative ion mist device 14 is fixedly installed on the front of the sealing door 11. A controller 15 is fixedly connected to the right side of the preservation box 10, and the controller 15 is electrically connected to the low-voltage electrostatic generator 13 and the negative ion mist device 14. A temperature control mechanism 20 is provided on the top of the preservation box 10.

[0022] In use, aquatic products are stored in the storage drawer 12. When in use, the sealing door 11 is closed, and the controller 15 activates the negative ion mist device 14 and the low-voltage electrostatic generator 13 via an external power supply. The negative ion mist device 14 releases negative ion mist, causing dust and bacteria inside the preservation box 10 to carry negative ions, enhancing the electrostatic adsorption of dust and bacteria within the box, making the surface of the aquatic products cleaner, and inhibiting the growth of microorganisms on the surface of the aquatic products, thus extending their shelf life. The low-voltage electrostatic generator 13 generates low-voltage static electricity, adsorbing dust and bacterial particles carried on the surface of the aquatic products, thereby extending their shelf life. The combined effect of the negative ion mist device 14 and the low-voltage electrostatic generator 13 effectively preserves the freshness of aquatic products.

[0023] refer to Figure 1 , 2 The temperature control mechanism 20 includes a water tank 201 fixedly connected to the top of the preservation box 10. A heater 206 is fixedly installed on the front of the water tank 201, and a semiconductor cooling chip 205 is fixedly installed on the rear side of the water tank 201. A circulation pump 202 is fixedly connected to the right side of the water tank 201. The input end of the circulation pump 202 is connected to the water tank 201 through a pipe, and the output end of the circulation pump 202 is fixedly connected to a connecting pipe 203. The other end of the connecting pipe 203 is connected to a metal bend through a flange. 204. A heat exchange tank 211 is formed on the rear side of the preservation box 10. The surface of the heat exchange tank 211 near the rear side of the preservation box 10 is fixedly connected to a metal bend 204. The other end of the metal bend 204 is fixedly connected to a water inlet pipe 207 through a flange. The other end of the water inlet pipe 207 is fixedly connected to a water tank 201. A temperature sensor is installed inside the preservation box 10. The temperature sensor, the circulation pump 202, the heater 206 and the semiconductor cooling chip 205 are electrically connected to the controller 15.

[0024] Preferably, the metal bends 204 are mirror-symmetrical and arranged in an "S" shape, with a rectangular cross-section. This allows one side surface of the metal bends 204 to fully contact the surface of the heat exchange tank 211, and the S-shaped arrangement provides a larger contact area with the heat exchange tank 211, increasing the efficiency of heat conduction or cooling.

[0025] Before use, the temperature range inside the food storage box 10 should be set in advance, and the real-time temperature inside the food storage box 10 should be fed back by the temperature sensor.

[0026] When the temperature inside the refrigerator 10 is higher than the set temperature range, the controller 15 starts the semiconductor cooling chip 205 and the circulation pump 202 through an external power supply. The contact end of the semiconductor cooling chip 205 cools the water inside the water tank 201, and at the same time, the built-in fan dissipates the heat, achieving the effect of continuously cooling the water inside the water tank 201. Meanwhile, the output end of the circulation pump 202 delivers the cooled water into the metal bend 204. When the low-temperature water flows in the metal bend 204, it will reduce the temperature inside the refrigerator 10 through heat transfer. Then the water flows back into the water tank 201 through the water inlet pipe 207, thereby achieving the effect of circulating cooling of the refrigerator 10 until the temperature inside the refrigerator 10 drops back to the set temperature range.

[0027] When the internal temperature of the food storage box 10 is lower than the set temperature, the controller 15 starts the heater 206 through an external power supply. The heater 206 heats the water in the water tank 201. The controller 15 then starts the circulation pump 202 through an external power supply. The input end of the circulation pump 202 draws high-temperature water from the water tank 201 through a pipe and discharges it into the metal bend 204 through the connecting pipe 203. The high-temperature water flows in the metal bend 204 and transfers heat into the food storage box 10 through heat transfer, raising the internal temperature of the food storage box 10. After flowing through the metal bend 204, the water enters the water tank 201 again through the water inlet pipe 207, thus achieving the effect of circulating heating. When the internal temperature of the food storage box 10 reaches the set value, the controller 15 reduces the heating power of the heater 206 so that the internal temperature of the food storage box 10 can be maintained within the set temperature range.

[0028] Furthermore, a water replenishment pump 208 is fixedly connected to the top of the preservation box 10. The output end of the water replenishment pump 208 is fixedly connected to the water tank 201 through a connecting pipe. An electric control valve 212 is installed on the connecting pipe. A water replenishment pipe 209 is fixedly connected to the input end of the water replenishment pump 208. The water replenishment pipe 209 includes a horizontal pipe and a vertical pipe connected vertically. A connector is fixedly connected to the bottom of the vertical pipe. A water replenishment bottle 210 is threaded to the bottom of the connector. A water level sensor is installed inside the water tank 201. The water level sensor, the electric control valve 212, and the water replenishment pump 208 are electrically connected to the controller 15.

[0029] During use, the water level sensor detects the liquid level inside the water tank 201. When the liquid level is lower than the set value, the controller 15 opens the electric control valve 212 and simultaneously starts the water replenishment pump 208 through the external power supply. The water replenishment pump 208 draws water from the water replenishment bottle 210 through the water replenishment pipe 209, and then the output end of the water replenishment pump 208 injects the water into the water tank 201 through the connecting pipe until the liquid level inside the water tank 201 reaches a suitable height; thus achieving the effect of automatically replenishing water to the water tank 201.

[0030] refer to Figure 3 , 4 The bottom of the preservation box 10 is provided with a moving mechanism 30. The moving mechanism 30 includes a support frame 301 fixedly connected to the bottom of the preservation box 10. The top of the support frame 301 can be fixedly connected to a bidirectional cylinder 302 through an installation component. The left and right output ends of the bidirectional cylinder 302 are respectively fixedly connected to L-shaped plates 303. The L-shaped plate 303 includes a vertically connected vertical plate and a horizontal plate. The bottom of the horizontal plate is fixedly connected to a guide rod 304. A horizontal block 305 is slidably connected to the outside of the guide rod 304. The bottom of the horizontal block 305 is fixedly connected to a pair of connecting blocks 306 arranged in a front-back arrangement. The bottom of the connecting block 306 is fixedly installed with a universal wheel 309. The front and rear sides of the inside of the support frame 301 are respectively provided with a pair of left-right mirror symmetrical path grooves 307. The inside of the path groove 307 is rotatably connected to a rolling rod 308. The inner end of the rolling rod 308 is rotatably connected to the corresponding horizontal block 305. Preferably, the bottom of the guide rod 304 is provided with a sealing plate.

[0031] Preferably, the pair of path grooves 307 on the same side are in a figure-eight shape. When not in use, the rolling rod 308 is located at the highest point of the path groove 307, so that a set of casters 309 does not contact the ground. When the aquatic products need to be rotated, in order to facilitate the movement of the preservation box 10 between factory buildings, the bidirectional cylinder 302 is started by an external power supply. The output ends on the left and right sides of the bidirectional cylinder 302 extend outward, driving the two L-shaped plates 303 to move in opposite directions. This drives the cross block 305 to move outward through the guide rod 304. At the same time, the cross block 305 drives the rolling rod 308 to roll along the inside of the path groove 307, so that the cross block 305 moves downward while moving outward, so that a set of casters 309 contacts the ground to support the preservation box 10 until the rolling rod 308 moves to the lowest point of the path groove 307. At this time, a set of casters 309 supports the entire device. Then, the preservation box 10 can be moved conveniently by rolling on the ground by the casters 309. When not in use, a set of casters 309 can be retracted into the support frame 301 in the opposite way, and the support frame 301 supports the food storage box 10, making it easy to place the whole device stably.

[0032] The working principle of this invention is as follows: During use, the controller 15 activates the negative ion mist device 14 and the low-voltage electrostatic generator 13 via an external power supply. The negative ion mist device 14 releases negative ion mist, causing dust and bacteria inside the preservation box 10 to carry negative ions, enhancing the adsorption of dust and bacteria by the electrostatic charge inside the box, making the surface of aquatic products cleaner, and also inhibiting the proliferation of microorganisms on the surface of aquatic products, thus extending the shelf life of aquatic products. Meanwhile, the low-voltage electrostatic generator 13 generates low-voltage static electricity, adsorbing dust and bacterial particles carried on the surface of aquatic products, thereby extending the storage period of aquatic products. The combination of the negative ion mist device 14 and the low-voltage electrostatic generator 13 effectively achieves the effect of preserving aquatic products.
