Description

Technical Field

[0001] This invention relates to the field of hydrogen preservation technology, and particularly to hydrogen-based preservation devices and their usage methods. Background Technology

[0002] Hydrogen-based preservation devices are equipment that uses hydrogen as a medium for preservation. They utilize the antioxidant, anti-apoptotic, and antibacterial properties of hydrogen to delay the oxidation and deterioration of fresh food, agricultural products, or biological samples and the proliferation of microorganisms, thereby extending the preservation period. They are widely used in the field of fresh produce preservation in supermarkets and stores.

[0003] Currently, existing hydrogen-based preservation devices for fresh produce in supermarkets, such as the hydrogen preservation process system and method disclosed in Chinese Invention Patent Publication No. CN119769553A, while using purified water as the electrolysis raw material and making the process clean and pollution-free, and hydrogen as a preservative gas being non-toxic, harmless, and environmentally friendly, in practical applications, this device can only be used as a single, dedicated cabinet. Its hydrogen production, circulation, control, and storage spaces are pre-designed and inseparable, which lacks flexibility for supermarket use. Furthermore, the need to purchase separate equipment leads to high costs and limited scalability. Therefore, this application provides a hydrogen-based preservation device and its application method to meet this need. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a hydrogen-based preservation device and its usage method. This solves the problems that existing hydrogen-based preservation devices are traditional, pre-designed, and indivisible units, which lack flexibility for use in supermarkets.

The air inlet pipe is located in the middle of the rear end of the middle layer box. The left end of the air inlet pipe is connected to the horizontal pipe. The upper end of the horizontal pipe has air outlets distributed laterally. The right end of the horizontal pipe is connected to the U-shaped pipe.

[0008] Preferably, the placement box includes a baffle, side walls, pull rods, and protrusions. The baffle has side walls at both ends, pull rods are provided on the front and rear sides of the upper end of the side walls, and protrusions are provided on the left and right sides of the upper end of the side walls.

[0009] Preferably, the inner support module includes an inner support wall, a bottom plate, a partition plate, a vent plate, and reinforcement holes. The bottom plate is provided at the lower end of the inner support wall. The partition plates are provided on the front and rear sides of the upper end of the bottom plate. The vent plate is embedded in the inner side of the upper end of the bottom plate. Reinforcement holes are provided parallel to each other on the left and right sides of the outer end of the inner support wall.

[0010] Preferably, the support module includes a front support plate, a rear support plate, side support plates, a perforated plate, and connecting bolts. The rear support plate is provided on the rear side of the front support plate. Side support plates are provided on the left and right sides of the outer ends of the front and rear support plates. A perforated plate is embedded in the inner side of the upper end of the front and rear support plates. Connecting bolts are threaded on the contact end between the front and rear support plates.

[0011] Preferably, the electrolysis module includes an electrolytic cell, an electrical connection terminal, a water inlet, an oxygen inlet, and a hydrogen inlet.

The water inlet is provided in the lower center of the front end of the electrolytic cell. The oxygen inlet is provided on the left side above the water inlet, and the hydrogen inlet is provided on the right side of the oxygen inlet.

[0012] Preferably, the contact end between the diversion module and the placement box is sealed by welding; the opening and closing plate is sleeved with the base; two transparent flip covers are symmetrically distributed front and back; the placement box and the transparent flip cover are sleeved with each other, and the contact end between the two is limited and reinforced by a plug rod; four electric telescopic rods are symmetrically distributed, and a ball bearing is embedded in the inner side of the upper end of the electric telescopic rod; a groove is opened at the contact end between the transparent flip cover and the ball bearing; and the support module and the inner support module are reinforced into an integrated structure.

[0013] Preferably, there are two hydraulic assembly boxes symmetrically distributed on the left and right, and four lifting columns symmetrically distributed on the left and right, with two columns on each side. The lifting columns are connected to the hydraulic assembly boxes via pipelines.

[0014] The method of using the hydrogen-based food preservation device includes the following steps: Step 1: Before starting hydrogen production, the hydraulic assembly box drives the lifting column to lift the diversion module, separating the base from the diversion module. Then, water is injected into the water supply tank. After injection, the lifting column descends, allowing the base and diversion module to contact and support each other. Then, power is supplied through the constant current box, and the circulating water pump draws water from the water supply tank. After passing through the resin filter, the water is injected into the electrolysis module to start the electrolysis hydrogen production process. Step 2: After separating hydrogen from water vapor using a gas-water separator, hydrogen is injected into the gas mixing tank through a pipeline. At the same time, the nitrogen generator will also start working to produce nitrogen, which is then injected into the gas mixing tank to mix with the hydrogen inside. Once the gas mixture is complete, the pressure reducing and stabilizing valve connected to the outside of the gas mixing tank will transport the mixed gas to the inlet pipe in the distribution module. Step 3: Through the array arrangement of horizontal tubes in the diversion module and the U-shaped tube connecting the array of horizontal tubes, the array of horizontal tubes forms an integrated pipeline, allowing the mixed gas to fill the inside of the integrated pipeline, and the mixed gas is discharged from the gas outlet, gradually permeating into the placement box from bottom to top, so as to preserve the vegetables and fruits inside the placement box with hydrogen. Step 4: When there are no customers at night, use the electric telescopic rod to lower the two transparent flip-tops to close the transparent flip-tops and the storage box. Then, activate the high-intensity hydrogen preservation mode for Step 1. During business hours, the transparent flip-tops and the storage box need to be opened, and the low-intensity hydrogen preservation mode is activated for Step 1. Step 5: During the hydrogen preservation process, the refrigeration box located in the base will also start cooling simultaneously, combining traditional refrigeration and hydrogen preservation to improve the overall preservation effect.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, a diversion module is installed in the middle area between the base and the placement box, separating the two vertically. The interior of the base is then modified by moving the refrigeration box to the right side of the base box. A hydrogen generator, gas mixing tank, and nitrogen generator are arranged on the left side of the base box. Combined with the openable transparent flip-top of the placement box, this transforms traditional equipment. By using hydrogen preservation combined with refrigeration to keep fruits and vegetables fresh, the entire design can be seamlessly integrated into existing equipment, fundamentally empowering it, significantly reducing the barriers and costs of technology promotion, and also reducing energy consumption.

[0016] With the hydraulic assembly box and lifting column, liftable supports are formed on the left and right sides of the lower end of the diversion module. During maintenance, the diversion module and the upper placement box can be easily raised as a whole, separating them from the base and exposing the equipment layout inside the base, thus improving the speed and convenience of maintenance.

[0017] In summary, this invention seamlessly integrates the design of the hydrogen preservation structure into existing equipment, fundamentally empowering existing equipment, greatly reducing the threshold and cost of technology promotion, and also achieving the advantage of reducing energy consumption.

There are two hydraulic assembly boxes 16 symmetrically distributed on the left and right sides, and four lifting columns 17 symmetrically distributed on the left and right sides, with two on each side. The lifting columns 17 and the hydraulic assembly boxes 16 are connected by pipelines.

[0028] By installing the diversion module 2 in the middle area between the base 1 and the placement box 3, the base 1 and the placement box 3 are separated vertically. Then, the interior of the base 1 is modified by moving the refrigeration box 102 to the right side of the base box 101. The hydrogen production box 103, gas mixing tank 104 and nitrogen generator 105 are arranged on the left side of the base box 101. With the transparent flip-top 6 that can be opened and closed at the top of the placement box 3, the traditional equipment is modified to preserve vegetables and fruits by combining hydrogen preservation with refrigeration. The whole design can be seamlessly integrated into the existing equipment, fundamentally empowering the existing equipment, greatly reducing the threshold and cost of technology promotion, and also reducing energy consumption. Secondly, by installing the hydraulic assembly box 16, together with the lifting column 17, a liftable support is formed on the left and right sides of the lower end of the diversion module 2. During maintenance and upkeep, the diversion module 2 and the upper placement box 3 can be easily raised to separate them from the base 1, exposing the equipment layout inside the base 1, improving the speed and convenience of maintenance and upkeep.

[0029] like Figures 1 to 5 As shown, in this embodiment, the base 1 includes a base box 101, a cooling box 102, a hydrogen production box 103, a gas mixing tank 104, and a nitrogen generator 105. The cooling box 102 is located on the right side inside the base box 101, the hydrogen production box 103 is located on the front left side inside the base box 101, and the gas mixing tank 104 is located on the right side behind the hydrogen production box 103.

The diversion module 2 includes a middle layer box 201, an inlet pipe 202, and a horizontal pipe 2. 03. Air outlet 204 and U-shaped tube 205. An air inlet pipe 202 is provided in the middle of the rear end of the middle layer box 201. The left end of the air inlet pipe 202 is connected to a horizontal pipe 203. An air outlet 204 is distributed horizontally at the upper end of the horizontal pipe 203. The right end of the horizontal pipe 203 is connected to a U-shaped tube 205. The placement box 3 includes a baffle 301, a side wall 302, a pull rod 303 and a protrusion 304. The left and right ends of the baffle 301 are provided with side walls 302. The front and rear sides of the upper end of the side wall 302 are provided with pull rods 303. The left and right sides of the upper end of the side wall 302 are provided with protrusions 304.

[0030] The base box 101 is a modified version of an existing supermarket refrigerated display case base or showcase base. Different installation spaces are created by welding plates at different positions and angles inside. Since the refrigeration box 102, gas mixing tank 104, and nitrogen generator 105 are all existing, well-established devices, they will not be discussed in detail here. The hydrogen generator 103 is explosion-proof. The internal layout of the hydrogen generator 103 includes a conductive strip 10, an electrolysis module 11, a water supply tank 12, a gas-liquid separator 13, a circulating water pump 14, and a resin filter 15. The specific arrangement of these components is not detailed in the provided text. The installation angle can be freely selected according to actual needs. Secondly, the contact ends of the base box 101 with the refrigeration box 102, hydrogen generator 103, gas mixing tank 104, and nitrogen generator 105 are all reinforced with bolts. The hydrogen generator 103 and nitrogen generator 105 are both interconnected with the gas mixing tank 104. The gas mixing tank 104 is equipped with a hydrogen concentration sensor and a pressure reducing valve. Since the hydrogen concentration sensor and pressure reducing valve are accessories of the gas mixing tank 104 and belong to existing known technologies, they will not be discussed further in this article. The top surfaces of both the refrigeration tank 102 and the hydrogen production tank 103 are sealed with bolts. The middle tank 201 is a one-piece design. The lower end of the inlet pipe 202 penetrates the interior of the lower end of the middle tank 201 and continues downward to the outside, where it is connected to the pressure reducing and stabilizing valve installed on the outer end of the gas mixing tank 104 via a sealed pipeline. The horizontal pipes 203 are arranged in a front-to-back array. Only the horizontal pipes 203 that are connected to the inlet pipe 202 are shorter, and the left side of the foremost horizontal pipe 203 is sealed. The other horizontal pipes 203 are of equal length. At the same time, both ends of the other horizontal pipes 203 are connected to... The U-shaped tubes 205 are combined to form an integrated pipeline. Next, each horizontal tube 203 is supported on both sides by a support kit. The air outlets 204 are arranged horizontally and are interconnected with the horizontal tubes 203. There are two baffles 301 symmetrically distributed at the front and back, and two side walls 302 symmetrically distributed on the left and right. The two baffles 301 and the two side walls 302 are welded into an integrated structure. There are four tie rods 303 symmetrically distributed on the left and right, two on each side. There are two protrusions 304 symmetrically distributed on the left and right. The interior of the two protrusions 304 is provided with a socket hole.

[0031] By installing the diversion module 2 in the middle area between the base 1 and the placement box 3, the base 1 and the placement box 3 are separated vertically. The interior of the base 1 is then modified by welding plates inside the base box 101 to create different spaces on the left and right sides. A refrigeration box 102 is installed in the right space, and a hydrogen production box 103, a gas mixing tank 104, and a nitrogen generator 105 are installed in the left space. Combined with the openable transparent flip-top 6 on the top of the placement box 3, the traditional equipment is modified without abandoning it, giving it hydrogen preservation capabilities in addition to traditional refrigeration and preservation. This fundamentally empowers the existing equipment. Yes, and the entire design can be seamlessly integrated into existing equipment, greatly reducing the threshold and cost of technology promotion. Secondly, when preservation is required, the two transparent flip covers 6 are lowered by the electric telescopic rod 7, so that the transparent flip covers 6 and the placement box 3 are closed. Then, the horizontal pipe 203 and U-shaped pipe 205 arranged in the diversion module 2 are combined into an integrated pipeline. When hydrogen is injected into the integrated pipeline from the inlet pipe 202, the hydrogen is discharged at a planar angle by the outlet nozzles 204 distributed in the array at the upper end of the integrated pipeline. Based on the characteristics of hydrogen itself, it permeates the vegetables and fruits placed and stored from bottom to top, achieving the effect of preservation.

[0032] like Figures 1 to 7 As shown, in this embodiment, the inner support module 5 includes an inner support wall 501, a bottom plate 502, a partition plate 503, a breathable plate 504, and reinforcing holes 505. The lower end of the inner support wall 501 is provided with the bottom plate 502, the front and rear sides of the upper end of the bottom plate 502 are provided with partition plates 503, the inner side of the upper end of the bottom plate 502 is embedded with a breathable plate 504, and the left and right sides of the outer end of the inner support wall 501 are provided with parallel reinforcing holes 505; support module 8 includes a front support plate 801, a rear support plate 802, a side support plate 803, a perforated plate 804, and a connecting bolt 805. The rear support plate 802 is provided on the rear side of the front support plate 801. The side support plates 803 are provided on the left and right sides of the outer ends of the front support plate 801 and the rear support plate 802. The perforated plate 804 is embedded in the inner side of the upper end of the front support plate 801 and the rear support plate 802. The connecting bolt 805 is threaded on the contact end between the front support plate 801 and the rear support plate 802.

[0033] The inner support wall 501 and the base plate 502 are integrated. Partition plates 503 are welded parallel to each other at a certain interval on the front and rear sides of the upper end of the base plate 502. Ventilation plates 504 are laid and installed between the parallel intervals of the partition plates 503. Reinforcing holes 505 are symmetrically and parallelly opened on the outer walls of the left and right ends of the inner support wall 501. The front support plate 801 and the rear support plate 802 are equal in size, shape, installation angle, and installation height. The side support plates 803 are symmetrically distributed left and right. 03 is an integral structure with the front support plate 801 and the rear support plate 802. The front support plate 801 has two side support plates 803 distributed on the left and right sides of its outer end, and the rear support plate 802 has two side support plates 803 distributed on the left and right sides of its outer end. The hollow plate 804 is embedded in the inner side of the upper end of the front support plate 801 and the rear support plate 802. The front end of the connecting bolt 805 passes through the interior of the front support plate 801, the inner support wall 501 and the rear support plate 802 from the front side, and extends to the rear outer side for reinforcement with nuts.

[0034] With the internal support module 5, which is embedded in the placement box 3 and reinforced with bolts at their left and right contact ends, the lower end of the placement box 3 can be designed as a hollow structure. The internal support module 5, together with the support module 8, forms a double-layer structure for placing vegetables and fruits. At the same time, gas can pass through the bottom of both the internal support module 5 and the support module 8. Through the horizontal pipe 203 and U-shaped pipe 205 arranged in the diversion module 2, they are combined into an integrated pipeline. When hydrogen is injected into the integrated pipeline from the inlet pipe 202, the gas outlets 204 arranged in the array at the upper end of the integrated pipeline discharge the hydrogen at a planar angle. Based on the properties of hydrogen itself, it permeates the placed and stored vegetables and fruits from bottom to top, achieving a preservation effect.

[0035] like Figures 8 to 13 As shown, in this embodiment, the electrolysis module 11 includes an electrolytic cell 111, a power connection terminal 112, a water inlet 113, an oxygen inlet 114, and a hydrogen inlet 115. The power connection terminals 112 are provided on the left and right sides of the upper end of the electrolytic cell 111. The water inlet 113 is provided in the lower middle part of the front end of the electrolytic cell 111. The oxygen inlet 114 is provided on the left side above the water inlet 113, and the hydrogen inlet 115 is provided on the right side of the oxygen inlet 114.

[0036] The electrolytic cell 111 is an integral structure with two electrical terminals 112 distributed on the left and right sides. The lower ends of both electrical terminals 112 extend into the interior of the electrolytic cell 111. The water inlet 113, oxygen inlet 114, and hydrogen inlet 115 are all interconnected with the interior of the electrolytic cell 111. The water inlet 113 is interconnected with the resin filter 15, the oxygen inlet 114 is interconnected with the water supply tank 12, and the hydrogen inlet 115 is interconnected with the gas-water separator 13. The water outlet at the bottom of the gas-water separator 13 is interconnected with the water supply tank 12, and the hydrogen outlet at the top of the gas-water separator 13 is interconnected with the gas mixing tank 104.

[0037] When water enters the electrolytic cell 111 through the inlet 113, the conductive strip 10 connects the terminal 112 to the constant current box 9, thus initiating electrolysis of the water. The generated oxygen is recovered from the oxygen port 114 and fed into the water supply tank 12 before being discharged. The generated hydrogen is injected into the gas-water separator 13 through the hydrogen port 115 for gas-water separation, and then enters the gas mixing tank 104. The entire electrolysis process can be controlled by the constant current box 9, and the electrolysis efficiency can be adjusted according to the actual situation. The electrolysis efficiency can be increased at night and decreased during the day.

[0038] The electrical components mentioned in this article are all connected to an external main controller and mains power, and the main controller can be a conventional known device such as a computer that provides control.

[0039] When using a hydrogen-based food preservation device, the following steps are included: Step 1: Before starting hydrogen production, the hydraulic assembly box 16 drives the lifting column 17 to work, allowing the lifting column 17 to push the diversion module 2 to rise, separating the base 1 from the diversion module 2. Then, water is injected into the water supply tank 12. After the injection is completed, the lifting column 17 descends, allowing the base 1 and the diversion module 2 to contact and support each other. Then, power is supplied through the constant current box 9, and the circulating water pump 14 draws water from the water supply tank 12. After being filtered by the resin filter 15, the water is injected into the electrolysis module 11 to start the electrolysis hydrogen production process. Step 2: After separating hydrogen and water gas through gas-water separator 13, hydrogen is injected into gas mixing tank 104 through pipeline. At the same time, nitrogen generator 105 will also start working to produce nitrogen and inject it into gas mixing tank 104 to mix with the hydrogen inside. After the gas is mixed, the pressure reducing and stabilizing valve connected to the outer end of gas mixing tank 104 will transport the mixed gas to the inlet pipe 202 in the diversion module 2. Step 3: Through the array arrangement of the horizontal pipes 203 in the diversion module 2, and the U-shaped pipes 205 that connect the array arrangement of the horizontal pipes 203 together, the array arrangement of the horizontal pipes 203 forms an integrated pipeline, allowing the mixed gas to fill the inside of the integrated pipeline, and the mixed gas is discharged through the gas outlet 204, gradually permeating into the placement box 3 from bottom to top, and hydrogen preservation of the vegetables and fruits inside the placement box 3. Step 4: When there are no customers at night, use the electric telescopic rod 7 to lower the two transparent flip covers 6, so that the transparent flip covers 6 and the placement box 3 are closed. Then, activate the high-intensity hydrogen preservation mode for Step 1. During business hours, the transparent flip covers 6 and the placement box 3 need to be opened, and the low-intensity hydrogen preservation mode is activated for Step 1. Step 5: During the hydrogen preservation process, the refrigeration box 102 located in the base 1 will also start refrigeration simultaneously, combining traditional refrigeration preservation with hydrogen preservation to improve the overall preservation effect.

[0040] The technical solution provided by this invention is as follows: A hydraulic assembly box 16 drives a lifting column 17, which in turn lifts the diversion module 2, separating the base 1 from the diversion module 2. Water is then injected into the water supply tank 12. After injection, the lifting column 17 descends, allowing the base 1 and the diversion module 2 to contact and support each other. Power is then supplied by a constant current electrical box 9, and a circulating water pump 14 draws water from the water supply tank 12. After filtration by a resin filter 15, the water is injected into the electrolysis module 11 to begin hydrogen electrolysis. Hydrogen is then separated from water vapor by a gas-water separator 13, and the hydrogen is injected into a gas mixing tank 104 via a pipeline. Simultaneously, a nitrogen generator 105 starts operating, producing nitrogen which is injected into the gas mixing tank 104 to mix with the internal hydrogen. Once the gas mixture is complete, a pressure reducing and stabilizing valve connected to the external end of the gas mixing tank 104 releases the mixed gas. The mixed gas is delivered to the intake pipe 202 in the diversion module 2 and injected into an integrated pipeline composed of a horizontal pipe 203 and a U-shaped pipe 205. The mixed gas fills the inside of the integrated pipeline and is discharged through the outlet 204. It gradually permeates into the placement box 3 from bottom to top, keeping the vegetables and fruits inside the placement box 3 fresh with hydrogen. When there are no customers at night, the two transparent flip covers 6 are lowered by the electric telescopic rod 7, so that the transparent flip covers 6 and the placement box 3 are closed. Then, the high-intensity hydrogen preservation mode is activated in step one. During business hours, the transparent flip covers 6 and the placement box 3 need to be opened. At this time, the low-intensity hydrogen preservation mode is activated in step one. During the hydrogen preservation process, the refrigeration box 102 located in the base 1 will also start refrigeration at the same time. Traditional refrigeration preservation and hydrogen preservation work together to improve the overall preservation effect.
