[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] First embodiment

[0035] The present invention provides Figures 1 to 8The multi-temperature zone control device with spatial potential physical preservation technology shown is used in cold chain logistics equipment, including a shell 1 and an air intake component 2. The air intake component 2 can collect the hot air located above, so as to reduce the temperature inside the space and prevent the temperature inside the space from rising and causing food to spoil. The air intake component 2 is arranged above the shell 1, and the hot air will move upward. The air intake component 2 is located above to make it more convenient to collect air. A slide 3 is provided in the middle of the bottom wall of the air intake component 2, and a push plate 4 is slidably connected inside the slide 3. The push plate 4 can move along the trajectory of the slide 3, thereby playing a certain restraining role and avoiding misalignment during movement. The upper surface of the push plate 4 and the top wall of the slide 3 are filled with expansion material, and the expansion material can be adjusted according to the ambient temperature. When the temperature rises, it expands; on the contrary, when the temperature drops, it shrinks. When the expansion material expands due to heat, it can drive the push plate 4 to move downward, so as to achieve the purpose of freely adjusting the position of the push plate 4. A potential generator 5 is provided on the bottom surface of the push plate 4, and a fixing frame 6 is provided on the outer surface of the potential generator 5. A static generating rod is provided on the bottom surface of the potential generator 5. When the potential generator 5 is energized, an electric field can be formed, which is emitted by the static generating rod, and the vibration frequency is released in the space. By making the water molecules in the atmosphere and objects resonate (the vibration can drive and enhance the vibration amplitude of the surrounding), an electric field is formed. Under the resonance effect of the electric field, the water molecules can resonate, affecting the water structure and the combination state of water and enzyme, resulting in enzyme inactivation, which helps to inhibit the biochemical reaction in fruits and vegetables, thereby maintaining their freshness.

[0036] The bottom surface of the air intake component 2 is connected to a plurality of exhaust pipes 7 distributed in a rectangular shape, and the inner diameter of the middle part of the exhaust pipe 7 is larger than the inner diameter of the two ends. The exhaust pipe 7 can cool the hot air introduced into the air intake component 2 and then quickly discharge it, thereby achieving the purpose of hot air consumption and avoiding excessive hot air from causing the overall temperature to rise and causing food to spoil. A support rod 8 is slidably connected to the inside of each exhaust pipe 7. A rubber disk 9 is provided at the upper end of each support rod 8, and the diameter of the rubber disk 9 is equal to the inner diameter of the two ends of the exhaust pipe 7. The position of the rubber disk 9 can be adjusted according to the internal temperature of the air intake component 2. When the temperature gradually increases, the rubber disk 9 can gradually move downward to the middle part of the exhaust pipe 7, so that a gap appears between the inner wall of the exhaust pipe 7 and the outer surface of the rubber disk 9, allowing airflow to pass through, thereby achieving the purpose of transmitting airflow. The lower end of each support rod 8 is fixedly connected to the upper surface of the fixed frame 6.

[0037] The air intake assembly 2 includes an air storage box 201, which can store hot air. The space is small, and the internal temperature will rise sharply, causing the expansion material to expand rapidly and drive the push plate 4 to move, thereby achieving the purpose of free movement of the push plate 4. The outer surface of the air storage box 201 is connected with two groups of air intake pipes 202 arranged at equal distances. The lower end of each group of air intake pipes 202 is connected with an air intake hopper 203, and the side surfaces of the two air intake hoppers 203 close to each other are fixedly connected to the outer surface of the shell 1. The inlet of the air intake hopper 203 is larger than the internal diameter, so that it is more convenient to absorb hot air. Two symmetrical slide grooves 10 are provided between the air storage box 201 and the shell 1, and each slide groove 10 is connected to the exhaust pipe 7 close to it. The interior of each slide groove 10 is slidably connected with a wind baffle 11, and the wind baffle 11 can The exhaust pipe 7 can be cut off to prevent hot air from being discharged from the exhaust pipe 7. The upper surface of each wind baffle 11 is provided with three equidistantly arranged air inlet holes 12, and the cross-section of each air inlet hole 12 is an inverted isosceles trapezoid. When the air inlet hole 12 and the exhaust pipe 7 overlap, the exhaust pipe 7 can be connected, and the gas can be discharged freely. The cross-section of the air inlet hole 12 is an inverted isosceles trapezoid. When the gas passes through the air inlet hole 12, it can be compressed to cool the discharged gas, and then it is transported to the vicinity of the food through the exhaust pipe 7, and combined with water vapor to make the preservation effect better. The side surfaces of the two wind baffles 11 away from each other are fixedly connected with a plurality of equidistantly arranged first springs 13, and the other end of each group of first springs 13 is fixedly connected to the inner wall of the slide groove 10 close to it, and each first spring 13 is in an initial state.

[0038] The left and right side walls of the slide 3 are provided with two symmetrical through grooves 14, and each through groove 14 is slidably connected with a squeezing plate 15, and the side surface of each squeezing plate 15 close to the support rod 8 is in an arc shape. When the push plate 4 moves downward and contacts the squeezing plate 15, the push plate 4 can be squeezed to the inside of the through groove 14, driving the two air baffles 11 away from each other, so that the air inlet 12 and the exhaust pipe 7 overlap, so that the exhaust pipe 7 can be closed or opened, and each squeezing plate 15 is fixedly connected to the air baffle 11, and the inner bottom wall of the slide 3 is fixedly connected with three second air baffles 11 arranged at equal distances. Spring 16, and each second spring 16 is in an initial state, the second spring 16 can play a certain supporting role on the push plate 4, when the force on the push plate 4 decreases, it can exert pressure on the second spring 16, so that the second spring 16 produces a reset elastic force, when the force of the push plate 4 disappears, under the action of the second spring 16, the push plate 4 can be restored to its original position, and a distance sensor is provided on the inner bottom wall of the slide 3, and the distance sensor can monitor the distance between the push plate 4 and the distance sensor in real time. The smaller the distance, the more hot air enters the air intake component 2, and then the hot air outside the surface is more, and the overall temperature is high.

[0039] The present invention also provides a cold chain logistics equipment, including a vehicle body 17 and two symmetrical multi-temperature zone control devices with space potential physical preservation technology. A freezer 18 is provided on the upper surface of the vehicle body 17, and a partition 19 is provided on the inner wall of the freezer 18. The partition 19 can divide the freezer 18 into two spaces. The components in each space can work freely without interference. A water tank 20 is provided on the rear side of the partition 19. A water pump 21 is provided on the upper surface of the water tank 20. The output end of the water pump 21 is connected to a water inlet pipe 22. The outer surface of the water inlet pipe 22 is provided with an electronic valve 23. The electronic valve 23 can control Water flow, and the size of the water flow changes with the distance detected by the distance sensor. The smaller the distance, the larger the corresponding water flow, thereby increasing the amount of water mist sprayed. The water mist absorbs external heat when evaporating, thereby driving the overall temperature down, improving the food preservation effect, and avoiding spoilage. The upper part of the front side of the partition 19 is connected to a sprinkler pipe 24, and the sprinkler pipe 24 is located above a multi-temperature zone control device with spatial potential physical preservation technology. The ground of the sprinkler pipe 24 is connected to a plurality of equidistantly arranged atomizing nozzles 25, and the upper end of the water inlet pipe 22 is connected to the left end of the sprinkler pipe 24.

[0040] Two groups of symmetrical guide rods 26 and linear guide rails 27 are fixedly connected between the inner walls of the freezer 18, and the outer surface of each guide rod 26 is sleeved with a guide cylinder 28, and each guide cylinder 28 is fixedly connected to the multi-temperature zone control device with spatial potential physical preservation technology that is close to it. With the mutual cooperation of the guide cylinder 28 and the guide rod 26, the multi-temperature zone control device with spatial potential physical preservation technology can be moved smoothly to avoid shaking or vibration during high-speed movement. The moving end of each linear guide rail 27 is fixedly connected to the upper surface of the multi-temperature zone control device with spatial potential physical preservation technology that is close to it. The movement speed of the linear guide rail 27 is bound to the distance detected by the distance sensor. The closer the distance, the faster the movement speed of the linear guide rail 27, so as to avoid the situation that some food is far away from the potential generator 5 when the potential generator 5 moves and deteriorates. Two symmetrical refrigerators 29 are arranged above the front and rear walls of the freezer 18. The refrigerator 29 can blow out cold air to reduce the internal temperature of the freezer 18, and maintain the freshness of the food by cooling.

[0041] In actual use, firstly, the refrigerator 29 is started to generate cold air to reduce the overall temperature inside the freezer 18, and then the water pump 21 is started to spray the water inside the water tank 20 from the atomizing nozzle 25 through the water inlet pipe 22, the electronic valve 23 and the sprinkler pipe 24 in sequence, so as to cooperate with the cooling and further improve the freshness preservation rate. Finally, the linear guide 27 and the potential generator 5 are started to make the potential generator 5 move left and right, so that the electric field generated by the potential generator 5 can cover more food. Under the resonance effect of the electric field, the water molecules can resonate, affecting the water structure and the combination state of water and enzyme, resulting in enzyme inactivation, which helps to inhibit the biochemical reaction in fruits and vegetables, thereby maintaining their freshness.

[0042] When the freezer 18 is opened, some outside air will enter the freezer 18 or when the car stops, the refrigerator 29 stops working, causing the overall temperature of the freezer 18 to rise, and the following adjustments are required:

[0043] The temperature inside the freezer 18 gradually increases, and the hot gas will gradually move upward, so that the hot gas gradually approaches the air intake assembly 2, and then enters the air storage box 201 through the air intake hopper 203 and the air intake pipe 202 in turn. When the hot gas inside the air storage box 201 gradually increases and the internal space of the air storage box 201 is small, the internal temperature of the air storage box 201 will gradually rise, so that the expansion material inside the slide 3 will expand, thereby pushing the push plate 4 to move downward and driving the potential generator 5 to move downward, and the movement distance gradually increases. At this time, the distance detected by the distance sensor gradually decreases, and the electronic valve 23, the linear guide 27 and the refrigerator 29 are started at the same time. Under the action of the electronic valve 23, the water flow entering the sprinkler pipe 24 gradually increases as the temperature inside the freezer 18 increases, thereby increasing the water mist sprayed from the atomizing nozzle 25. In the process of evaporation, the heat absorption effect gradually increases to prevent the food from spoiling due to the increase in temperature. Under the action of the refrigerator 29, the generated cold air gradually increases as the temperature inside the freezer 18 increases, and the overall temperature is reduced again with the water mist, further improving the freshness preservation rate. Under the action of the linear guide 27, the speed of the potential generator 5 to move left and right can be driven to increase, thereby increasing the contact time between the electric field and the food, and preventing the food from being out of contact with the electric field for a long time.

[0044] Under the action of the push plate 4, the fixed frame 6 can drive the multiple support rods 8 to gradually move downward, and at this time the inside of the exhaust pipe 7 is sealed. Driven by the support rods 8, the rubber disc 9 gradually moves downward, so that the negative pressure generated inside the exhaust pipe 7 gradually increases. At the same time, the distance that the potential generator 5 follows the push plate 4 to descend gradually increases, so that the distance between it and the food gradually decreases, so that the food can gradually approach the center of the electric field, thereby making its preservation rate better. When the push plate 4 gradually moves downward and contacts with multiple extrusion plates 15, under the action of extrusion, the two wind baffles 11 can be pushed away from each other, so that the air inlet 12 and the exhaust pipe 7 overlap, so that the upper end of the exhaust pipe 7 can be opened. Under the action of negative pressure, the gas inside the gas storage box 201 can be introduced into the exhaust pipe 7. At the same time, the rubber disc 9 moves to the middle of the exhaust pipe 7, so that the exhaust pipe 7 is completely connected, so that the gas can circulate inside the exhaust pipe 7. When the gas passes through the air inlet 12, the gas can be compressed, so that the discharged gas is cooled down, and then transported to the vicinity of the food through the exhaust pipe 7, combined with water vapor, so that the preservation effect is better.

[0045] As the hot air inside the air storage box 201 continuously reacts with the expansion material, the hot air is continuously consumed. When the exhaust pipe 7 is opened, the unreacted hot air can be cooled and then discharged, so that the hot air inside the freezer 18 can be absorbed and converted, and the hot air is continuously consumed, so that the overall temperature inside the freezer 18 can be reduced, avoiding the situation where the cold air discharges the external hot air into the interior every time the freezer 18 is opened, causing the temperature of the freezer 18 to rise and causing the food to rot.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
