[0031] according to Figure 1-Figure 4 , Fig. 9 and Fig.10As shown, a connecting pipe 115 is installed at the output end of the compressor 114, and the output end of the connecting pipe 115 is movable through the surface of the partition 109.

With the cooperation of the main fixing plate 118 and the auxiliary fixing plate 119, the evaporator 117 can be protected and a support point can be provided for the evaporator 117.

[0032] according to Figure 2-Figure 4 , Figure 7 and Fig.10 As shown, the main fixing plate 118 is movably sleeved inside the storage tank 120, and an auxiliary fixing plate 119 is installed at the bottom of the main fixing plate 118, and the auxiliary fixing plate 119 is inside the storage tank 120.

[0033] according to Figure 2-Figure 4 , Figure 7 and Fig.10 As shown, the output end of the capillary 116 is installed with the input end of the evaporator 117, and the output end of the evaporator 117 is installed with the return pipe 102, the output end of the return pipe 102 is movable through the surface of the partition 109, the output end of the return pipe 102 is connected to the input end of the compressor 114, and the inner wall of the placement groove 108 is installed with a temperature sensor 121, and the detection end of the temperature sensor 121 extends to the interior of the storage tank 120. Under the action of the temperature sensor 121, the temperature inside the storage tank 120 can be known.

[0034] according to Figure 1-Figure 4 , Figure 6 and Fig.10 As shown, the battery 112 is electrically connected to the controller 107, and the compressor 114, the temperature sensor 121, the small generator 203, the concentration sensor 212, the condenser 110 and the hot air blower 218 are all electrically connected to the controller 107. Two cylindrical holes 3 are provided on one side of the partition 109 near the bottom, so that the temperature sensor 121 and the condenser 110 can be connected to the controller 107 with wires under the action of the cylindrical holes 3.

[0035] The effect achieved by the entire mechanism is: when the processed aquatic products need to be quickly frozen and preserved, the battery 112 is first used to power the controller 107, and then the temperature threshold (the temperature for quick freezing and preservation of aquatic products) and the concentration threshold (the ozone concentration threshold is determined according to actual conditions) are set, and then the low-temperature and low-pressure refrigerant gas is injected into the compressor 114, and then the compressor 114 and the fan of the condenser 110 are started by the controller 107 and the temperature sensor 121 is turned on. At this time, the compressor 114 is started to compress the injected low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas, and it is discharged from its output end and transported to the inside of the connecting pipe 115, and then transported to the inside of the condenser 110. When the high-temperature and high-pressure gas enters the cold When the condenser 110 is turned on, the condenser 110 will use the placement slot 108, the mesh plate 105 and the corresponding installation slot 104 to absorb the low-temperature air in the environment, and then let the low-temperature air exchange heat with the condenser 110, take away the heat, and discharge it from the heat dissipation holes of the back plate 111 to the environment. Then, the high-temperature and high-pressure gas after the heat exchange will become a high-temperature and high-pressure liquid, and then be discharged from the output end of the condenser 110 and enter the interior of the capillary 116. When the high-temperature and high-pressure liquid enters the interior of the capillary 116, the capillary 116 will cause the pressure and temperature of the high-temperature and high-pressure liquid entering it to drop sharply, turning it into a low-temperature and low-pressure liquid. Then, the low-temperature and low-pressure liquid will be transported to the evaporator 117. When the high-pressure liquid enters the evaporator 117 inside the storage tank 120, the heat inside the storage tank 120 will be absorbed by the low-temperature and low-pressure liquid, allowing the internal space of the storage tank 120 to cool down rapidly. Subsequently, the low-temperature and low-pressure liquid that absorbs the heat will become a low-temperature and low-pressure gas, and then be transported back to the compressor 114 through the cooperation of the return pipe 102 to start a new cycle. At the same time, the temperature sensor 121 will also monitor the temperature inside the storage tank 120 at all times, and transmit the temperature data detected each time to the controller 107 in the form of an electrical signal. Subsequently, the controller 107 will compare each received temperature data with the temperature threshold value set in advance by the controller 107. When the temperature data received by the controller 107 is higher than the temperature threshold value set in advance by the controller 107, the controller 107 will receive the temperature data. When the temperature threshold value preset by the controller 107 is lower than the threshold value, the controller 107 will not turn off the compressor 114 and the fan on the condenser 110. When the temperature data received by the controller 107 is the same as the threshold value preset by the controller 107, the controller 107 will turn off the compressor 114 and the fan on the condenser 110. When the temperature data received by the controller 107 again is lower than the threshold value preset by the controller 107, the controller 107 will start the compressor 114 and the fan on the condenser 110 again to continue cooling down. This reciprocating process can not only keep the internal temperature of the storage tank 120 at a temperature that meets the quick-freezing and fresh-keeping temperature of aquatic products, but also achieve energy saving. After the quick-freezing and fresh-keeping box has been quick-frozen for a period of time, the box door 103 is opened.Then, the box containing the processed aquatic products is placed on the main fixing plate 118 inside the storage tank 120 and on the bottom of the inner wall of the storage tank 120, and then the box door 103 is closed. At this time, the processed aquatic products in the storage tank 120 can be quickly frozen and preserved. When the quick-freezing and fresh-keeping box is finished using and the cleaning operation is completed, the box door 103 is directly closed, and then the back plate 111 is removed from the box body 101, and then the threaded ends of the two hand screws 215 are removed from the inner wall of the placement groove 108, and then the two auxiliary blocks 214 are removed, and the two hand screws 216 are also removed at the same time, and then the two hollow blocks 206 are moved inside the corresponding rectangular holes 205. At this time, one of the moving hollow blocks 206 will drive the L-shaped tube 2 11. The manual valve 210, the one-way valve 208, the three-way pipe 209, the corresponding connecting block 213 and the round tube 207 move synchronously. When the surface of the connecting block 213 contacts the surface of the placement groove 108, the interior of one of the hollow blocks 206 is just connected to the interior of the placement groove 108. Then, the threaded end of the corresponding hand screw 216 is screwed into the interior of the corresponding threaded groove 220, so that one of the hollow blocks 206 that has moved can be fixed. At the same time, the other moving hollow block 206 will drive the concentration sensor 212 and the corresponding connecting block 213 to move synchronously. When the surface of the connecting block 213 contacts the inner wall of the placement groove 108, the interior of the other hollow block 206 is just connected to the inner wall of the placement groove 108. 8 is connected to the inside, and then the threaded end of the corresponding hand screw 216 is screwed into the inside of the corresponding threaded groove 220, so that the other hollow block 206 after the move can be fixed, and then the small generator 203 (ozone generator) is started by the controller 107, and then the valve on the top of the gas cylinder 202 is manually opened. When the top valve of the gas cylinder 202 is opened, the oxygen in the gas cylinder 202 will be quickly discharged and enter the inside of the connecting pipe 204 connected thereto, and then enter the inside of the small generator 203. Then, the oxygen entering the small generator 203 will be ionized and reacted, and then ozone will be generated and discharged. Then, the discharged ozone will enter the inside of the connecting pipe 204 connected thereto, and then enter the round tube 207, and finally transported to the interior of the storage tank 120 through the cooperation of the one-way valve 208, one of the hollow blocks 206 and the three-way pipe 209. When ozone is continuously transported to the interior of the storage tank 120, the concentration sensor 212 is turned on by the controller 107. The concentration sensor 212 started at this time will detect the ozone concentration inside the storage tank 120, and transmit the concentration data obtained each time to the controller 107 in the form of an electrical signal. When the concentration data received by the controller 107 is lower than the concentration threshold value set in advance by the controller 107, the controller 107 will not turn off the small generator 203. When the concentration data received by the controller 107 is the same as the concentration threshold value set in advance by the controller 107,At this time, the controller 107 will turn off the small generator 203, and then the staff will close the valve of the gas cylinder 202, that is, use the ozone with a sufficient concentration inside the storage tank 120 to disinfect the storage tank 120 and the parts inside the storage tank 120. After the storage tank 120 and the internal parts of the storage tank 120 have been disinfected for a period of time, the box door 103 is directly opened to allow the ozone in the storage tank 120 to dissipate. When the residual ozone in the storage tank 120 needs to be quickly decomposed, one of the hollow blocks 206 is first unfixed and then moved back to the initial position, and then the manual valve 210 is opened, and then one of the hollow blocks 206 is moved to a position where it can be fixed, and then it is fixed, and then the controller 107 is used to start the hot air blower 218, and the box door 103 is closed at the same time. The hot air blower 218 started at this time will suck in the air inside the placement tank 108, then heat it, and then discharge it to the inside of the air guide shell 219, and then to the inside of the air pipe 217, and then to the inside of the L-shaped tube 211, and then to the inside of the opened manual valve 210, and finally to the inside of the storage tank 120 through the cooperation of the three-way pipe 209. When the hot air enters the inside of the storage tank 120, the hot air can accelerate the speed of decomposing the residual ozone in the storage tank 120 into oxygen. When the hot air is transported to the inside of the storage tank 120 for a period of time, the controller 107 is used to turn off the hot air blower 218, and then wait for a period of time, and then open the box door 103, that is, the disinfection operation of the quick-freezing fresh-keeping box is completed, and then all components are reset to their original positions, and it can be used next time.
