Description

Technical Field

[0001] This invention relates to the field of egg preservation equipment technology, specifically to a method and device for efficient egg preservation and quality grading using intelligent environmental control. Background Technology

[0002] During storage, the internal quality of eggs gradually declines as storage time increases and the external environment changes. Therefore, in egg preservation equipment, it is usually necessary to control the temperature, humidity and airflow of the storage space to delay the loss of water and the deterioration of the quality of eggs.

[0003] Most existing egg preservation devices use a cabinet combined with tiered egg racks for storage, and achieve egg preservation through fan circulation, temperature detection, or drawer-type storage space. Some also use dampers to regulate the air volume or temperature and humidity of local spaces to improve the uniformity of the cabinet environment and preservation conditions.

[0004] However, existing structures typically lack immediate isolation and airflow guidance for the opened layer when pulling out and placing eggs in the tiered egg rack. This results in the layer remaining connected to the main air duct in the initial stage of pulling out, making it easy for the controlled air to leak out ineffectively along the opening path. Furthermore, the airflow entering this layer can directly affect the egg storage area, leading to a longer environmental recovery time before and after pulling out this layer, which is not conducive to maintaining the consistency of the freshness of eggs in each layer. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a method and apparatus for efficient preservation and quality grading of eggs using intelligent environmental control, aiming to alleviate the aforementioned problems to at least some extent.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A smart environmental control-based high-efficiency egg preservation device, comprising: Food storage container; Multiple first partitions are disposed inside the food preservation box, and the multiple first partitions divide the inside of the food preservation box into multiple preservation layers; A drawer located within the preservation layer is used to store eggs; A first compartment is located on one side of the preservation box, and a second compartment is provided on the top of the preservation box; A refrigeration component installed on the second housing is used to reduce the gas temperature inside the second housing; An air intake component located inside the first box is used to draw gas from the second box and deliver it into the preservation layer. When the drawer leaves the predetermined position of the corresponding preservation layer, the air intake component stops intake and stores gas; when the drawer enters the predetermined position of the corresponding preservation layer, the air intake component delivers the stored gas into the corresponding preservation layer.

[0007] Preferably, a door is hinged to one side of the food storage box; The door of the box is provided with a plurality of first magnetic strips, and the body of the preservation box is connected with a second magnetic strip that is magnetically attracted to the first magnetic strips.

[0008] Preferably, the refrigeration component includes a refrigeration unit disposed on the second housing, with its output end located inside the second housing.

[0009] Preferably, the second box body has a first opening, and the first opening is provided with a one-way valve for air intake into the second box body; the preservation layer has a second opening, and the second opening is also provided with a one-way valve for air exhaust to the outside. The one-way valve includes a connecting pipe with a sleeve that slides inside it. A baffle is connected to the end of the sleeve, and multiple air ports are opened on the side wall of the sleeve. A first spring is connected between the sleeve and the connecting pipe.

[0010] Preferably, the second housing is connected to multiple conveying pipes, and the second housing is connected to multiple second partitions, which divide the second housing into multiple air intake chambers, and each conveying pipe is connected to the corresponding air intake chamber.

[0011] Preferably, a third partition is connected inside the air intake chamber, and a rubber elastic sheet is also connected to the air intake chamber body. The third partition and the rubber elastic sheet separate the air intake chamber into a cold air chamber, a conveying chamber and a compression chamber. The conveying pipe is connected to the air intake chamber, and multiple cold air pipes are connected inside the conveying chamber. The cold air pipes extend into the preservation layer.

[0012] Preferably, the air intake component includes multiple rotating shafts, which are rotatably connected to each of the cooling air chambers and extend to the outside of the first housing. Multiple protruding rods are connected to the rotating shafts. A one-way tube is fixed on the third partition. A sliding tube is slidably connected to the one-way tube. Multiple connection ports are opened on the side wall of the sliding tube. A baffle is connected to the top of the sliding tube. A second spring is connected between the sliding tube and the one-way tube. A piston is slidably connected inside the one-way tube. Multiple air inlets are opened on the outer wall of the one-way tube. A connecting rod is rotatably connected to the protruding rod. The top of the connecting rod is rotatably connected to the piston.

[0013] Preferably, a motor is provided on one side of the first housing, the output shaft of the motor is connected to one of the rotating shafts, and a chain drive mechanism is provided between adjacent rotating shafts.

[0014] Preferably, a limiting rod is connected inside the preservation layer, a baffle is slidably connected to the limiting rod, a third spring is connected between the baffle and the limiting rod, the baffle is located on one side of the air conditioning pipe, and a wedge-shaped strip is connected to the bottom of the baffle.

[0015] An egg quality grading method, applicable to any of the above-mentioned high-efficiency egg preservation devices, includes the following steps: Place the eggs to be graded into drawers corresponding to the multiple preservation layers inside the preservation box; The gas inside the second chamber is cooled by a refrigeration component installed on the second chamber. When the corresponding drawer is in the predetermined position of the corresponding preservation layer, the cooled gas is delivered to the corresponding preservation layer through the air intake component, and the original gas in the corresponding preservation layer is discharged to the outside. When the corresponding drawer leaves the predetermined position of the corresponding preservation layer, the air intake component is controlled to stop air intake into the corresponding preservation layer and store the gas; When the corresponding drawer re-enters the predetermined position of the corresponding preservation layer, the air intake component is controlled to deliver the stored gas to the corresponding preservation layer; Based on the number of times each drawer leaves the predetermined position of the corresponding preservation layer, the duration of each drawer leaving the predetermined position of the corresponding preservation layer, and the storage gas return status of each corresponding preservation layer, the preservation process parameters corresponding to each preservation layer are determined. Based on the preservation process parameters corresponding to each preservation layer, the eggs in that preservation layer are graded according to quality.

[0016] In summary, the present invention has the following main beneficial effects: Compared with existing technologies, this application firstly addresses the issue of insufficient targeted control of the egg storage environment in each layer by setting a first chamber, a second chamber, and air intake paths corresponding to each storage layer on the outside of the refrigerator. This allows cold air to be delivered layer by layer to the corresponding storage layer, thus avoiding the problem of insufficient targeted control of the egg storage environment in a unified air supply system. Secondly, by setting a structure that coordinates the change of drawer position with the air intake switching, the corresponding layer stops direct air intake and stores cold air when the drawer leaves the predetermined position. After the drawer returns to its original position, the stored cold air is delivered to the corresponding storage layer, thereby reducing the ineffective leakage of cold air along the opening path and shortening the time required for the corresponding storage layer to return to its storage state before and after being pulled out. In addition, by setting an opening and closing mechanism at the end of the cold air pipe and a temporary storage mechanism between the delivery chamber and the compression chamber, the opened layer can be isolated from the air supply path in a timely manner during the pulling process and can achieve rapid replenishment of cooling after returning to its original position. This reduces the disturbance caused by the direct effect of airflow on the egg storage area and improves the consistency of the egg storage state in each storage layer. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] refer to Figures 1-10 This embodiment provides an intelligent environmental control egg high-efficiency preservation device, including a preservation box 100, multiple first partitions 101, multiple drawers 103, a first box 104, a second box 105, a refrigeration component, and an air intake component.

[0021] The preservation box 100 forms the main preservation space for eggs. Multiple first partitions 101 are disposed within the preservation box 100 and spaced apart along the height of the preservation box 100 to divide the interior of the preservation box 100 into multiple vertically distributed preservation layers 102. Each preservation layer 102 is independently arranged to accommodate a corresponding drawer 103. Each drawer 103 corresponds one-to-one with each preservation layer 102, and the drawer 103 can move relative to the preservation box 100 along the entry and exit direction of the corresponding preservation layer 102 to facilitate the placement, removal, and layered storage of eggs.

[0022] The first chamber 104 is located on one side of the preservation chamber 100, and the second chamber 105 is located on the top of the preservation chamber 100. The second chamber 105 serves as a pretreatment space for the gas to be cooled, and the first chamber 104 serves as a gas delivery space. The second chamber 105 and the first chamber 104 are connected to each other so that the gas located in the second chamber 105 can enter the first chamber 104. The first chamber 104 is connected to multiple preservation layers 102 respectively so that the gas entering the first chamber 104 can be further delivered to the corresponding preservation layer 102. By arranging the second chamber 105 on the top of the preservation chamber 100 and the first chamber 104 on the side of the preservation chamber 100, the cooled gas can be concentrated and cooled at the top first, and then uniformly delivered to each preservation layer 102 through the side, thereby facilitating the formation of a stratified gas supply path.

[0023] A refrigeration component is installed on the second chamber 105 to lower the gas temperature inside the second chamber 105, creating a low-temperature gas environment suitable for egg preservation. An air intake component is installed inside the first chamber 104 and communicates with the second chamber 105. It extracts the gas cooled by the refrigeration component from the second chamber 105 and delivers this gas to each preservation layer 102. To enable gas supply switching when the drawer 103 is pulled out, the air intake component has a gas storage function; that is, when gas supply to the open preservation layer 102 stops, it retains the extracted low-temperature gas inside itself for later resupply.

[0024] Each drawer 103 has a predetermined position for entering the corresponding preservation layer 102. This predetermined position is the working position after the drawer 103 is fully pushed into the corresponding preservation layer 102. In this state, the drawer 103 is essentially contained within the corresponding preservation layer 102, facilitating the formation of a relatively stable preservation environment around the drawer 103. When any drawer 103 leaves the predetermined position of the corresponding preservation layer 102, it indicates that the drawer 103 has moved outward from within the preservation layer 102 and entered an open / accessible state. At this time, the air intake component stops continuing to intake air into the corresponding preservation layer 102, and simultaneously stores the low-temperature gas originally intended for delivery to the corresponding preservation layer 102, instead of continuously supplying it into the open preservation layer 102. This design prevents the preservation layer 102 from continuously receiving low-temperature gas while open, thereby reducing the possibility of ineffective leakage of controlled gas along the opening path of the drawer 103.

[0025] When the drawer 103 re-enters its predetermined position in the corresponding preservation layer 102, it indicates that the drawer 103 has returned to the normal preservation state within the corresponding preservation layer 102. At this time, the air intake component delivers the previously stored gas to the corresponding preservation layer 102, enabling the corresponding preservation layer 102 to quickly return to a low-temperature preservation environment after the drawer 103 returns to its original position. In other words, during the period when the drawer 103 is pulled out, the air intake component does not continuously supply gas to the opened layer, but first stops the air intake to that layer and completes the temporary storage of gas; after the drawer 103 returns to its original position, the temporarily stored gas is then delivered back to that layer to improve the environmental restoration efficiency of the corresponding preservation layer 102.

[0026] Based on the above embodiment, a door 106 is hinged to one side of the food preservation box 100. The door 106 is located on the access side of each preservation layer 102 and each drawer 103, and can rotate relative to the food preservation box 100 between an open position and a closed position. When the door 106 is in the closed position, the door 106 blocks the access opening of the food preservation box 100, so that each drawer 103 is located inside the door 106. When the door 106 is in the open position, the door 106 makes way for the pull-out path of each drawer 103, so that the corresponding drawer 103 can be moved out or pushed back along the inlet and outlet direction of the preservation layer 102.

[0027] In actual use, when a user needs to store or retrieve eggs, they can first rotate the door 106 to the open position, then pull out the drawer 103 in the corresponding preservation layer 102 to place, retrieve, or inspect the eggs. After completing the operation, the drawer 103 is pushed back to the predetermined position of the corresponding preservation layer 102, and the door 106 is rotated to the closed position. Thus, the opening actions of the door 106 and the drawer 103 work together, so that the drawer 103 is only exposed to the external environment when eggs need to be placed or retrieved, while in the non-operational state, the door 106 closes the opening side of the preservation box 100.

[0028] Based on the above embodiment, the door 106 is provided with a plurality of first magnetic strips 107, and the preservation box body 100 is connected with a second magnetic strip 108 that is magnetically connected to the first magnetic strips 107. The plurality of first magnetic strips 107 are spaced apart along one side of the door 106 toward the preservation box body 100.

[0029] When the door 106 is rotated from the open position to the closed position, as the door 106 gradually approaches the refrigerator body 100, the multiple first magnetic strips 107 on the door 106 are respectively attracted to the multiple second magnetic strips 108 on the refrigerator body 100, thereby keeping the door 106 stably closed. When it is necessary to open the door 106 to store or take out the eggs in the drawer 103, the user applies an opening force to the door 106, causing the first magnetic strips 107 and second magnetic strips 108 to disengage, thus rotating the door 106 to the open position. Since the multiple first magnetic strips 107 and multiple second magnetic strips 108 are distributed at corresponding positions on the door 106 and the refrigerator body 100, a relatively uniform attraction effect can be formed around the door 106 after it is closed.

[0030] Based on the above embodiments, the refrigeration component includes a refrigeration unit 109 disposed on the second housing 105, with its output end located inside the second housing 105. The refrigeration unit 109 is installed on the top or side top of the second housing 105 and is fixedly connected to the second housing 105, so that the output end of the refrigeration unit 109 extends into the interior of the second housing 105 to directly cool the gas inside the second housing 105. The second housing 105 serves as a gas pre-cooling space, where the gas temperature decreases after heat exchange with the output end of the refrigeration unit 109, thereby forming low-temperature gas suitable for delivery to each preservation layer 102.

[0031] The refrigeration unit 109 is installed on the second housing 105 as a conventional cooling component, and its output end is located inside the second housing 105 for cooling the gas inside the second housing 105.

[0032] After outside air enters the second compartment 105, the output of the refrigeration unit 109 continuously cools the gas inside the second compartment 105, maintaining a relatively stable low temperature state inside the second compartment 105. When the air intake component is working, it extracts the cooled gas from the second compartment 105 and delivers it to the corresponding preservation layer 102 to cool and regulate the storage environment of the eggs in the preservation layer 102. When the corresponding drawer 103 leaves the predetermined position of the corresponding preservation layer 102, the air intake component stops supplying air to the preservation layer 102 and stores the low-temperature gas. When the drawer 103 re-enters the predetermined position, the air intake component delivers the stored low-temperature gas to the corresponding preservation layer 102, thereby allowing the preservation layer 102 to quickly return to the predetermined low-temperature preservation state.

[0033] Based on the above embodiment, the second chamber 105 has a first opening 200, and a one-way valve 201 is provided in the first opening 200 for air intake into the second chamber 105. The preservation layer 102 has a second opening 202, and a one-way valve 201 is provided in the second opening 202 for air exhaust to the outside. The first opening 200 is used to allow external gas to enter the second chamber 105 so that it can be cooled by the refrigeration unit 109 in the second chamber 105 to form low-temperature gas to be transported. The second opening 202 is used to allow the gas in the corresponding preservation layer 102 to be discharged to the outside. By setting one-way valves 201 in the air intake direction and one-way valves 201 in the air exhaust direction on the second chamber 105 and the preservation layer 102 respectively, the air intake process of the second chamber 105 and the air exhaust process of the preservation layer 102 can be carried out in predetermined directions, thereby providing the basic conditions for cooling the gas in the second chamber 105 and renewing the gas in the preservation layer 102.

[0034] Based on the above embodiments, both the one-way valve 201 in the first opening 200 and the one-way valve 201 in the second opening 202 include a connecting pipe 203. A sleeve 204 is slidably fitted inside the connecting pipe 203. A baffle 205 is connected to the end of the sleeve 204. Multiple air ports 206 are opened on the side wall of the sleeve 204. A first spring 207 is connected between the sleeve 204 and the connecting pipe 203. The connecting pipe 203 is fixedly installed at the corresponding opening. The sleeve 204 moves relative to the connecting pipe 203 along the length direction of the connecting pipe 203. The baffle 205 is located at the end of the sleeve 204 and is set towards the corresponding opening direction. The first spring 207 is used to provide a reset function for the sleeve 204, so that the sleeve 204 maintains its initial position when there is no obvious air pressure pushing.

[0035] When gas flows in the permissible flow direction of the one-way valve 201, the flowing gas acts on the baffle 205, pushing the baffle 205 to move the sleeve 204 relative to the connecting pipe 203, and compressing the first spring 207. As the sleeve 204 moves, multiple air ports 206 on the side wall of the sleeve 204 connect with the flow space inside the connecting pipe 203, allowing gas to pass through the one-way valve 201 via the multiple air ports 206, thus achieving ventilation in the corresponding direction. Taking the one-way valve 201 located at the first opening 200 as an example, when external gas enters the second chamber 105, the gas pushes the baffle 205 and the sleeve 204 to move, opening the first opening 200 and allowing external gas to enter the second chamber 105. Taking the one-way valve 201 located at the second opening 202 as an example, when gas in the preservation layer 102 is discharged outward, the gas similarly pushes the baffle 205 and the sleeve 204 to move, opening the second opening 202 and allowing gas in the preservation layer 102 to be discharged to the outside.

[0036] When the gas pushing force in the permissible direction weakens or disappears, the first spring 207 pushes the sleeve 204 to reset, and the baffle 205 returns to the closed position along with the sleeve 204, causing the corresponding opening to close again. When external gas attempts to enter in the opposite direction, the baffle 205 remains in a blocking state on the flow path under the action of the first spring 207, thereby restricting the reverse flow of gas. By setting the one-way valve 201 to a structure in which the connecting pipe 203, sleeve 204, baffle 205, multiple air ports 206, and the first spring 207 cooperate with each other, the one-way valve 201 can automatically open under the action of forward airflow and automatically reset and close after the airflow weakens, thereby realizing one-way flow during the gas replenishment process of the second chamber 105 and the exhaust process of the preservation layer 102.

[0037] Based on the above embodiment, the second housing 105 is connected to multiple conveying pipes 300, and multiple second partitions 301 are connected inside the second housing 105. The multiple second partitions 301 divide the second housing 105 into multiple air intake chambers 302, and each conveying pipe 300 is connected to the corresponding air intake chamber 302. The multiple second partitions 301 are spaced apart along the width or length direction of the second housing 105 to divide the interior of the second housing 105 into multiple separated air intake chambers 302, and each air intake chamber 302 is connected to the corresponding conveying pipe 300.

[0038] After the refrigeration unit 109 cools the gas inside the second chamber 105, when the air intake component is working, it can draw gas from the corresponding air intake chamber 302 through the corresponding delivery pipe 300 and deliver it to the corresponding preservation layer 102. Since multiple air intake chambers 302 are formed by multiple second partitions 301 inside the second chamber 105, the gas source corresponding to each delivery pipe 300 is relatively independent, thus establishing separate gas supply paths for different preservation layers 102. Thus, when one of the drawers 103 leaves the predetermined position of the corresponding preservation layer 102, the air intake component stops supplying air to the preservation layer 102 corresponding to that drawer 103 and stores the gas in that path, while other delivery pipes 300 can still be connected to their corresponding air intake chambers 302 to continue supplying low-temperature gas to other preservation layers 102 that are in a normally closed state; when the drawer 103 re-enters the predetermined position of the corresponding preservation layer 102, the air intake component then supplies the gas stored in the corresponding path to the corresponding preservation layer 102.

[0039] Based on the above embodiment, a third partition 303 is connected inside the air intake chamber 302, and a rubber elastic sheet 304 is also connected inside the air intake chamber 302. The third partition 303 and the rubber elastic sheet 304 separate the air intake chamber 302 into a cold air chamber 305, a conveying chamber 306 and a compression chamber 307. The conveying pipe 300 is connected to the air intake chamber 302. A plurality of cold air pipes 308 are connected inside the conveying chamber 306, and the cold air pipes 308 extend into the preservation layer 102.

[0040] The third partition 303 is used to separate the gas flow area inside the air intake chamber 302. The rubber elastic sheet 304 is used to generate elastic deformation under gas pressure, thereby cooperating with the third partition 303 to form a conveying chamber 306 and a compression chamber 307 with temporary storage capacity. Multiple cold air pipes 308 are connected to the conveying chamber 306 and extend toward the corresponding preservation layer 102 to convey the cold air in the conveying chamber 306 to the corresponding preservation layer 102.

[0041] When drawer 103 is in the predetermined position of the corresponding preservation layer 102, the end of the corresponding cold air pipe 308 is in the open state. At this time, the air intake component continuously draws gas from the second compartment 105, creating a pressure difference in the air intake direction between the second compartment 105 and the outside. Under the action of this pressure difference, the one-way valve 201 in the first opening 200 on the second compartment 105 opens, and the outside gas enters the second compartment 105 through the first opening 200 and forms cold air under the action of the refrigeration component. The formed cold air enters the corresponding air intake chamber 302 through the delivery pipe 300. Since the end of the cold air pipe 308 is kept open at this time, the cold air in the delivery chamber 306 can enter the corresponding preservation layer 102 through multiple cold air pipes 308, and the gas in the delivery chamber 306 can be output in time. The rubber elastic sheet 304 basically remains in its natural state or only undergoes small deformation. As cold air continuously enters the preservation layer 102, the existing gas inside the preservation layer 102 is pushed outward through the second opening 202 by the newly entering cold air. The one-way valve 201 on the preservation layer 102 opens when the air pressure inside the preservation layer 102 is greater than the external air pressure, thereby achieving one-way discharge of the old gas. Thus, external gas is continuously cooled by the second chamber 105 and enters the preservation layer 102, while the existing gas inside the preservation layer 102 is continuously discharged, forming a circulating and renewed preservation airflow.

[0042] When drawer 103 leaves the predetermined position of the corresponding preservation layer 102, the end of the corresponding cold air pipe 308 is closed, and the cold air output path between the conveying chamber 306 and the corresponding preservation layer 102 is cut off. At this time, the air intake component continues to work, and the one-way valve 201 on the second housing 105 is still open under the action of the pressure difference in the air intake direction. Cold air continues to enter the corresponding air intake chamber 302 through the conveying pipe 300. Since the end of the cold air pipe 308 is closed, the cold air entering the conveying chamber 306 cannot continue to be discharged through the cold air pipe 308. The cold air in the conveying chamber 306 gradually increases and pushes the rubber elastic sheet 304 to deform towards the compression chamber 307, thereby giving the conveying chamber 306 a temporary space for cold air storage and causing the rubber elastic sheet 304 to form an elastic restoring tendency. When drawer 103 re-enters the predetermined position of the corresponding preservation layer 102, the end of the corresponding cold air pipe 308 reopens. Under its own elastic recovery, the rubber elastic sheet 304 pushes the temporarily stored cold air in the conveying chamber 306 into the corresponding preservation layer 102 through the cold air pipe 308. At the same time, the air intake component continues to deliver subsequent cold air to the preservation layer 102, so that the preservation layer 102 can quickly restore the cold air environment after drawer 103 returns to its original position.

[0043] Based on the above embodiments, the air intake component includes multiple rotating shafts 400, which are rotatably connected to each of the cooling air chambers 305 and extend to the outside of the first housing 104. Multiple protruding rods 401 are connected to the rotating shafts 400. A one-way tube 402 is fixed on the third partition 303. A sliding tube 403 is slidably connected to the one-way tube 402. Multiple connection ports 404 are opened on the side wall of the sliding tube 403. A baffle 405 is connected to the top of the sliding tube 403. A second spring 406 is connected between the sliding tube 403 and the one-way tube 402. A piston 407 is slidably connected inside the one-way tube 402. Multiple air inlets 408 are opened on the outer wall of the one-way tube 402. A connecting rod 409 is rotatably connected to the protruding rod 401. The top of the connecting rod 409 is rotatably connected to the piston 407. Each cooling chamber 305 is equipped with a corresponding rotating shaft 400. The rotating shaft 400 extends outside the first housing 104, making it easy to be driven to rotate by an external drive structure. When the rotating shaft 400 rotates, the protruding rod 401 drives the piston 407 to reciprocate within the one-way tube 402 via the connecting rod 409, thereby converting the rotation of the rotating shaft 400 into the reciprocating suction action of the piston 407. The one-way tube 402 is fixed to the third partition 303, forming a cooling air delivery path between the cooling chamber 305 and the delivery chamber 306. The sliding tube 403 is slidably engaged with the one-way tube 402, the baffle 405 is located on the air outlet side of the one-way tube 402, the second spring 406 is used to push the sliding tube 403 to reset, and multiple air inlets 408 and multiple connecting ports 404 are used to connect the cooling chamber 305 and the interior of the one-way tube 402 during the suction phase.

[0044] In actual operation, when drawer 103 is in the predetermined position of the corresponding preservation layer 102 and the end of the cold air pipe 308 is in the open state, the external drive structure drives the rotating shaft 400 to rotate continuously. The protruding rod 401 rotates with the rotating shaft 400 and drives the piston 407 to reciprocate through the connecting rod 409. When the piston 407 moves away from the baffle 405, a negative pressure is formed in the one-way pipe 402. The cold air in the cold air chamber 305 enters the one-way pipe 402 through the air inlet 408 and the connecting port 404 under the action of the pressure difference. At this time, the second spring 406 pushes the sliding tube 403 to maintain the reset state. The baffle 405 restricts the air outlet side of the one-way pipe 402 to prevent the gas in the conveying chamber 306 from flowing back into the one-way pipe 402. When the piston 407 moves downward past... When the air inlet 408 is in place, the cold air in the cold air chamber 305 can enter the one-way tube 402. When the piston 407 moves toward the direction close to the baffle 405, the gas in the one-way tube 402 is compressed. The sliding tube 403 moves relative to the one-way tube 402 against the elastic force of the second spring 406, so that the baffle 405 opens the air outlet side of the one-way tube 402. The cold air in the one-way tube 402 is compressed into the conveying chamber 306, and then enters the corresponding preservation layer 102 through the cold air pipe 308. As the air intake component continuously draws cold air from the cold air chamber 305, a pressure difference is formed in the second chamber 105 relative to the outside in the air intake direction. The one-way valve 201 on the second chamber 105 opens under the action of this pressure difference, allowing external air to enter the second chamber 105 and be cooled by the refrigeration component before being replenished into the corresponding cold air chamber 305. At the same time, after the cold air enters the preservation layer 102, it pushes the original gas in the preservation layer 102 to flow outward, causing the air pressure in the preservation layer 102 to increase relative to the outside. The one-way valve 201 on the preservation layer 102 opens under the action of this pressure difference, thereby expelling the old gas in the preservation layer 102 to the outside.

[0045] Based on the above embodiment, a motor 410 is provided on one side of the first housing 104. The output shaft of the motor 410 is connected to one of the rotating shafts 400, and a chain drive mechanism 411 is provided between adjacent rotating shafts 400. The motor 410 is fixedly installed on the outside of the first housing 104, and its output shaft passes through the side wall of the first housing 104 and is connected to one of the rotating shafts 400 as the driving rotating shaft 400; the remaining rotating shafts 400 serve as driven rotating shafts 400. Adjacent rotating shafts 400 are connected by the chain drive mechanism 411, so that each rotating shaft 400 can rotate synchronously under the drive of the same power source. The chain drive mechanism 411 may include sprockets respectively connected to adjacent rotating shafts 400 and a chain wound around the outside of the sprockets, so as to transmit the rotation of the driving rotating shaft 400 to the other rotating shafts 400 in sequence. This allows multiple rotating shafts 400 to rotate synchronously, achieving the purpose of air intake.

[0046] Based on the above embodiment, a limiting rod 500 is connected inside the preservation layer 102, and a baffle 501 is slidably connected to the limiting rod 500. A third spring 502 is connected between the baffle 501 and the limiting rod 500. The baffle 501 is located on one side of the air conditioning pipe 308, and a wedge-shaped strip 503 is connected to the bottom of the baffle 501. The limiting rod 500 is used to guide the movement of the baffle 501, and the third spring 502 is used to push the baffle 501 toward the end of the air conditioning pipe 308.

[0047] In the initial state, drawer 103 is located in the predetermined position of the corresponding preservation layer 102, and drawer 103 abuts against wedge strip 503 to push stop 501 upward. At this time, third spring 502 is in a compressed state, and end of cold air pipe 308 is in an open state. When drawer 103 leaves the predetermined position, drawer 103 disengages from wedge strip 503, third spring 502 releases elastic potential energy and pushes stop 501 downward to close end of cold air pipe 308; when drawer 103 re-enters the predetermined position, drawer 103 abuts against wedge strip 503 again and pushes stop 501 upward, third spring 502 is recompressed, and end of cold air pipe 308 reopens. Through the above structural cooperation, cold air pipe 308 can be automatically closed when drawer 103 leaves the position, and cold air pipe 308 can be automatically opened when drawer 103 returns to the position.

[0048] Based on the above embodiment, a temperature sensor is provided inside the preservation layer 102. The temperature sensor is used to detect the temperature information within the corresponding preservation layer 102, so as to know the temperature state of the egg storage environment within the corresponding preservation layer 102. The temperature sensor can be set on the side of the preservation layer 102 near the drawer or near the air outlet area of ​​the cold air pipe to detect the actual temperature within the corresponding preservation layer 102. After the refrigeration component cools the gas inside the second compartment, the air intake component delivers cold air to the corresponding preservation layer 102, and the temperature sensor simultaneously detects the temperature change within the preservation layer 102. When the drawer leaves the predetermined position, the corresponding preservation layer 102 stops direct air intake and enters the air storage stage; the temperature sensor can still detect the temperature state within the preservation layer 102. When the drawer re-enters the predetermined position, the stored cold air is delivered back to the corresponding preservation layer 102, and the temperature sensor can be used to reflect the temperature recovery status within the preservation layer 102.

[0049] This embodiment provides a method for grading egg quality, applicable to any of the egg high-efficiency preservation devices described above, and includes the following steps: First, the eggs to be graded are placed in the drawers corresponding to the various preservation layers inside the preservation box, and each drawer is pushed into its predetermined position within its respective preservation layer. When the drawer is in its predetermined position, the end of the corresponding cold air pipe is in the open state. The refrigeration unit cools the gas inside the second chamber, and the air intake unit delivers the cooled gas to the corresponding preservation layer, while simultaneously expelling the original gas in the corresponding preservation layer to the outside, so that each preservation layer is in a normal preservation state.

[0050] During egg preservation, when any drawer leaves its predetermined position in the corresponding preservation layer, this departure is recorded as an opening event, and the duration of this departure is recorded. The recording of the opening event's duration ends when the drawer re-enters its predetermined position in the corresponding preservation layer. Thus, the number of drawer departures and the cumulative departure duration within a preservation cycle can be obtained. The preservation cycle is the period from when the eggs are placed in the corresponding drawer until the batch of eggs is removed and graded.

[0051] In this embodiment, whether a drawer leaves a predetermined position and whether it re-enters the predetermined position can be identified by a position detection device installed at the predetermined position. The position detection device can be any one of a limit switch, a Hall effect switch, or a photoelectric switch. When the position detection device changes from an in-position state to an out-of-position state, it is recorded as the drawer leaving the predetermined position; when the position detection device returns from an out-of-position state to an in-position state, it is recorded as the drawer re-entering the predetermined position. The control unit records the number of times each drawer leaves its predetermined position and the duration of the departure based on the state change signal output by the position detection device. Thus, the "number of times each drawer leaves the predetermined position of its corresponding preservation layer" and the "duration of each drawer leaving the predetermined position of its corresponding preservation layer" are directly obtained by the position detection device in conjunction with the control unit.

[0052] When the drawer leaves the predetermined position of the corresponding preservation layer, the end of the corresponding cold air pipe is closed, and the air intake component stops directly supplying air to the preservation layer, but continues to work to deliver cold air to the corresponding conveying chamber and push the rubber elastic sheet to deform towards the compression chamber, thereby temporarily storing the cold air; when the drawer re-enters the predetermined position of the corresponding preservation layer, the end of the corresponding cold air pipe reopens, and the rubber elastic sheet, under the elastic recovery action, pushes the temporarily stored cold air in the conveying chamber to quickly enter the corresponding preservation layer.

[0053] Based on the above structure, in this embodiment, the "storage gas return situation corresponding to each preservation layer" is determined as follows: The gas delivery volume of each preservation layer's corresponding air intake path per unit time is pre-calibrated, and this unit time gas delivery volume is recorded as the standard gas delivery volume of the corresponding preservation layer. During the period when a drawer is in an off-position state, since the end of the corresponding cold air pipe is sealed and the air intake component continues to work, the amount of cold air entering the corresponding conveying chamber during this period is the storage gas volume corresponding to this opening event. The storage gas volume is obtained by multiplying the standard gas delivery volume of the corresponding preservation layer by the off-position duration of this opening event. After the drawer re-enters the predetermined position, the storage gas volume corresponding to this opening event is returned to the corresponding preservation layer via the cold air pipe; therefore, the returned gas volume corresponding to this opening event is equal to the storage gas volume corresponding to this opening event. The control unit accumulates the returned gas volume corresponding to each opening event to obtain the cumulative returned gas volume of the corresponding preservation layer throughout the entire preservation cycle.

[0054] Furthermore, to ensure that the "recirculation status" is not limited to the recirculation volume itself, this embodiment also includes the recirculation duration as a component of the recirculation status. Specifically, the recirculation volume per unit time of the air intake path after the drawer returns to its original position is pre-calibrated; for each opening event, after obtaining the amount of stored gas corresponding to that opening event, the amount of stored gas is divided by the recirculation volume per unit time to obtain the recirculation duration corresponding to that opening event; the control unit accumulates the recirculation durations corresponding to each opening event, thus obtaining the cumulative recirculation duration of the corresponding preservation layer throughout the entire preservation period. Therefore, in this embodiment, the "stored gas recirculation status" is characterized by both the cumulative recirculated gas volume and the cumulative recirculation duration.

[0055] Based on the above recording results, this embodiment defines the preservation process parameters corresponding to each preservation layer as: drawer displacement count parameter, cumulative drawer displacement duration parameter, cumulative gas return volume parameter, and cumulative gas return duration parameter. In other words, the preservation process parameters are not abstract concepts, but rather a set of parameters calculated by the control unit based on the drawer position change recording results and the calibrated gas delivery capacity and calibrated gas return capacity of the corresponding air intake path.

[0056] After obtaining the preservation process parameters, the eggs in each corresponding preservation layer are graded for quality. In this embodiment, a grading scoring method is used for quality grading. Specifically, grading thresholds are set for the parameters of drawer displacement frequency, cumulative drawer displacement time, and cumulative return duration, and corresponding scores are assigned according to the threshold range; wherein, the more drawer displacement frequency, the longer the cumulative drawer displacement time, and the longer the cumulative return duration, the higher the corresponding score. The three scores are added together to obtain the process score of the corresponding preservation layer, and the eggs in the preservation layer are graded for quality based on the process score.

[0057] For example, within a preservation cycle, if the drawer corresponding to a certain preservation layer is removed no more than twice, the removal frequency score is 0 points; if it is removed 3 to 5 times, the removal frequency score is 1 point; and if it is removed more than 5 times, the removal frequency score is 2 points. If the cumulative removal time of the drawer corresponding to that preservation layer is no more than 30 minutes, the removal time score is 0 points; if the cumulative removal time is between 30 and 90 minutes, the removal time score is 1 point; and if the cumulative removal time exceeds 90 minutes, the removal time score is 2 points. If the cumulative return time corresponding to that preservation layer is no more than 10 minutes, the return time score is 0 points; if the cumulative return time is between 10 and 30 minutes, the return time score is 1 point; and if the cumulative return time exceeds 30 minutes, the return time score is 2 points. Ultimately, when the process score is 0 to 1, the eggs in the preservation layer are classified as Grade 1 quality; when the process score is 2 to 3, the eggs in the preservation layer are classified as Grade 2 quality; and when the process score is 4 to 6, the eggs in the preservation layer are classified as Grade 3 quality.

[0058] In this embodiment, instead of simply "grading based on preservation process parameters," the process first utilizes the drawer's departure and return process, the continuous operation of the air intake component, and the gas return process in the conveying chamber to obtain the number of departures, departure duration, cumulative gas return volume, and cumulative return duration. Then, a process score is generated based on preset thresholds and scoring rules, ultimately completing the egg quality grading. In this way, the egg quality grading results directly correspond to the actual environmental disturbance process and cold air recovery process of the eggs during preservation, thus providing a clear technical basis and feasibility for the quality grading process.
