Abstract
Description
Technical Field
[0001] This invention relates to the field of egg preservation technology, and more specifically to a storage device for egg preservation. Background Technology
[0002] Eggs are an indispensable nutritious ingredient in daily family meals. In family life, it is extremely common for elders to send eggs to their children. For example, a mother might prepare free-range or fresh eggs for her son who is working or married, ensuring both nutrition and safety while also conveying family care. These eggs are mostly high-quality fresh eggs from home-raised or farm-sourced sources, and their requirements for storage, preservation, and transportation are far higher than those for ordinary commercial eggs.
[0003] Currently, the common methods for transporting eggs in households include simple pulp egg trays, ordinary plastic egg boxes, and cardboard boxes. However, these methods present numerous problems in practice and fail to meet the needs of safe, long-term, and convenient family transport. Traditional egg trays are mostly single-layered and lack clamping structures, making eggs prone to shaking, squeezing, and collisions during handling, transportation, and hand carrying. This can easily lead to eggshell breakage and leakage, causing not only losses but also contaminating the packaging of other eggs. The breakage rate is even higher during long-distance transport. Furthermore, the freshness of eggs deteriorates rapidly under high temperatures, making them prone to yolk spoilage and deterioration. Ordinary egg boxes are mostly fixed structures, requiring layer-by-layer operation for opening, closing, and egg removal. When multiple layers are stacked, repeated disassembly and reassembly are necessary. In some cases, the opening and closing mechanism and the tightness of the egg tray are independent, requiring separate adjustments when placing and removing eggs. This is strenuous and inefficient for the elderly. Summary of the Invention
[0004] This invention provides a storage device for preserving eggs, aiming to solve the problem in related technologies that eggs are prone to shell breakage and leakage during handling, transportation, and transport.
[0005] The present invention provides a storage device for preserving eggs, comprising: a base, four sets of side plate assemblies, four sets of folding assemblies, multiple sets of lower egg trays, multiple sets of upper egg trays, a top cover, and a drive assembly; The four sets of side panel assemblies are arranged to form an openable rectangular vertical frame and are all located on the top of the base. The lower egg tray and the upper egg tray are both located inside the rectangular vertical frame. The eggs are held between the lower egg tray and the upper egg tray. The top cover is closed on the top of the rectangular vertical frame. The base has an ice compartment at the bottom, a circulating fan inside the ice compartment, a vent at the top of the base connecting the ice compartment to the inside of the rectangular vertical frame, and a battery compartment on the side of the base to power the circulating fan. The driving component is located on the central axis of the rectangular vertical frame. The driving component is simultaneously connected to the four sets of folding components and is also connected to the upper egg tray. The drive assembly can drive the upper egg tray to move vertically up and down to release or clamp the egg, while simultaneously driving the four sets of folding assemblies to work synchronously, so that the four sets of side plate assemblies can fold outward or inward at the same time.
[0006] Preferably, the side plate assembly includes an upper side plate and a lower side plate that are hinged to each other. The lower side plate is rotatably mounted on the top of the base, a rotating plate one is rotatably connected to the upper side plate, and a rotating plate two is rotatably connected to the lower side plate.
[0007] Preferably, the folding assembly includes a gear and a lead screw, the lead screw being rotatably mounted between the base and the top cover, the gear being fixed to the lead screw, a rotating plate being screwed to the lead screw, and a rotating plate being rotatably connected to the lead screw.
[0008] Preferably, the drive assembly includes a gear ring, a lead screw, a fixing plate, and multiple guide rods. The gear ring is rotatably mounted on the bottom of the top cover. The lead screw passes through the middle of the gear ring, and a differential is provided between the lead screw and the gear ring. The fixing plate is located below the gear ring. The guide rods are fixedly connected between the fixing plate and the base. The lower egg tray is fixedly connected to the guide rod and rotatably sleeved on the lead screw. The upper egg tray is screwed to the lead screw and slidably sleeved on the guide rod. The gear ring simultaneously meshes with the gears of four sets of folding components.
[0009] Preferably, the upper egg tray and the lower egg tray each have an arc-shaped receiving groove adapted to the shape of the egg on their opposite sides.
[0010] Preferably, four connecting plates are fixedly connected to the side of the fixing plate, and four lead screws are respectively rotatably assembled on the corresponding connecting plates.
[0011] Preferably, a throttle is fixedly connected to the top of the second lead screw, and the throttle is located above the top cover.
[0012] Preferably, a handle is fixedly connected to the top of the top cover, and a latch for locking the relative positions of the top cover and the side panel assembly is provided.
[0013] The beneficial effects of this invention are: First, the upper and lower egg trays provide comprehensive fixation and cushioning for the eggs, effectively offsetting the vibration and impact during handling and vehicle bumps. Compared with traditional paper trays and egg boxes, it can reduce the breakage rate of eggs during family transportation (such as long-distance shipping and short-distance hand transport), ensuring that precious farm-fresh eggs are delivered intact, and reducing egg loss in scenarios such as "a mother delivering eggs to her son".
[0014] Second, the device integrates an ice compartment and a circulating fan, which can maintain a constant low temperature and low humidity environment inside, delaying the spoilage reaction of the egg liquid and the growth of microorganisms. Compared with ordinary ambient temperature packaging, its shelf life is extended, preserving the fresh taste and nutrients of free-range eggs to the greatest extent, ensuring that the recipient enjoys the best flavor.
[0015] Third, it adopts a linkage structure of side panel assembly folding and upper egg tray movement. When the side panel assembly is folded or unfolded, the upper egg tray moves up or down at the same time. No multi-step operation is required. Just turn screw two to complete the lifting and lowering of the multi-layer egg tray and the opening and closing of the side panel assembly. The overall operation is simple and labor-saving, and is suitable for the elderly to operate. Attached Figure Description

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0024] like Figures 1 to 6As shown, a storage device for preserving eggs according to the present invention includes: a base 10, a side plate assembly 20, a folding assembly 21, a lower egg tray 30, an upper egg tray 31, a top cover 40, and a driving assembly 50. The side plate assembly 20 is disposed on the top of the base 10 and has four sets, which can be combined to form a rectangular vertical frame. The lower egg tray 30 and the upper egg tray 31 are provided in multiple sets and located inside the rectangular vertical frame. Eggs are placed between the lower egg tray 30 and the upper egg tray 31. The top cover 40 is located on the top of the rectangular vertical frame. The driving assembly 50 is disposed on the central axis of the rectangular vertical frame. The driving assembly 50 can drive multiple upper egg trays 31 away from or closer to their corresponding lower egg trays 30, and can drive the folding assembly 21 to work, so that the side plate assembly 20 is folded, making it convenient to put in and take out eggs.
[0025] An ice compartment 11 is located at the bottom of the base 10, and a circulating fan is installed inside the ice compartment 11. A vent 13 is provided at the top of the base 10, leading to the interior of the ice compartment 11 and the interior of the rectangular vertical frame. When the circulating fan is turned on, the low-temperature air in the ice compartment 11 will be evenly transported to the entire interior of the rectangular vertical frame through the vent 13, providing a continuous low-temperature environment for the interior of the storage device, slowing down the loss of freshness of the eggs and extending the storage time of the eggs. A battery compartment 12 is also provided on the side of the ice compartment 11 to hold the battery that powers the circulating fan.
[0026] In other embodiments, the ice container 11 can be replaced with any heat exchange device.
[0027] Each of the four side panel assemblies 20 includes an upper side panel 201 and a lower side panel 202. The upper side panel 201 and the lower side panel 202 are hinged to each other. A rotating plate 1 2011 is rotatably connected to the upper side panel 201, and a rotating plate 2021 is rotatably connected to the lower side panel 202. The lower side panel 202 is rotatably mounted on the top of the base 10.
[0028] The folding assembly 21 has four sets corresponding to the side panel assembly 20, including gear 211 and lead screw 212. Lead screw 212 is rotatably mounted between the base 10 and the top cover 40, and gear 211 is fixedly connected to lead screw 212 and located near the top cover 40. Rotating plate 2011 is screwed to lead screw 212, and rotating plate 2021 is rotatably connected to lead screw 212. When lead screw 212 rotates, rotating plate 2011 moves along the axial direction of lead screw 212, and the lower side panel 202 rotates on the base 10. As a result, the upper side panel 201 and the lower side panel 202, which are hinged to each other, deflect at an angle and fold outward, so that the lower egg tray 30 and the upper egg tray 31 are exposed to the outside, allowing for the operation of taking and putting in eggs.
[0029] Both the upper egg tray 31 and the lower egg tray 30 have arc-shaped receiving grooves on their opposite sides to accommodate the shape of the eggs. This allows individual eggs to be placed separately, preventing them from colliding and breaking. It also allows low-temperature air to circulate better between the eggs, ensuring freshness.
[0030] A handle 41 is fixedly connected to the top of the top cover 40 to facilitate the movement and handling of the device. A buckle 42 is also provided between the side of the top cover 40 and the upper side plate 201 to lock the relative position between the top cover 40 and the side plate assembly 20, ensuring the structural stability of the device in the closed state.
[0031] The drive assembly 50 includes a gear ring 501, a lead screw 502, a fixing plate 503, and guide rods 504. The gear ring 501 is rotatably mounted on the bottom of the top cover 40. The lead screw 502 passes through the middle of the gear ring 501, and a differential 52 is provided between the lead screw 502 and the gear ring 501. The fixing plate 503 is located below the gear ring 501. Multiple guide rods 504 are fixedly connected between the fixing plate 503 and the base 10. The lower egg tray 30 is rotatably mounted on the lead screw 501. The upper egg tray 31 is screwed onto the second lead screw 502 and slidably connected to the guide rod 504. When the second lead screw 502 rotates, the lower egg tray 30 remains in the same position, and the upper egg tray 31 moves up and down along the axis of the second lead screw 502, thereby changing the distance between the upper egg tray 31 and the lower egg tray 30. This makes it easier to put in the eggs and hold them stably in the receiving slot, preventing the eggs from shaking and bumping during transportation and improving storage safety.
[0032] The gear ring 501 meshes with the gears 211 of the four folding components 21. The gear ring 501 can rotate under the drive of the lead screw 502, which in turn drives the gears 211 to rotate simultaneously, causing multiple side panel components 20 to fold at the same time. During the folding process, due to the rotation of the lead screw 502, the upper egg tray 31 moves away from the lower egg tray 30, thereby opening the side panel storage space and automatically releasing the clamp on the egg. This makes the operation of taking out and putting in eggs simpler, without the need to adjust the clamping structure and the side panel state separately. The preparation operation can be completed in one step, simplifying the usage process and improving the operating efficiency. When the top cover 40 is locked again, rotating the lead screw 502 in the opposite direction can close the side panel to complete the assembly, and at the same time, bring the upper egg tray 31 closer to the lower egg tray 30 to clamp the egg again, completing the automatic clamping and fixing. The overall structure has strong linkage and the operation logic is simple and smooth.
[0033] The differential 52 between lead screw 2 502 and gear ring 501 can adapt to different operating requirements, enabling the rotational speed of gear ring 501 and lead screw 2 502 to match the folding speed of folding component 21 and the vertical sliding speed of upper egg tray 31. This ensures that the clamping and releasing action of upper egg tray 31 and the side plate folding action can be completed synchronously, avoiding the situation where the eggs are damaged due to misalignment of action sequence. This makes the operation of the linkage structure more stable and smooth, ensures the structural fit accuracy, and improves the reliability of the device. At the same time, the clamping and storage actions of the entire storage device are all realized through the rotation linkage of lead screw 2 502, eliminating the need for multiple additional drive structures. The overall structure is simpler, reducing manufacturing costs and the difficulty of later maintenance, and also reducing the overall space occupied by the device.
[0034] Four connecting plates 22 are fixedly connected to the side of the fixed plate 503, and four lead screws 212 are respectively rotatably assembled on the four connecting plates 22 to improve the stability of the device.
[0035] The top of the lead screw 502 is equipped with a handle 51. By manually turning the handle 51, the lead screw 502 can be rotated, which can simultaneously complete the folding and unfolding of the side plate and the lifting and clamping of the upper egg tray 31 without the need for electric drive.
[0036] This storage device is based on manual drive, linkage control, low-temperature preservation, and anti-collision protection. It uses a transmission structure to synchronously complete the opening and closing of the side panels and the tightening and loosening of the egg trays. Combined with the cooling of the base 10, it can achieve safe, long-term, and convenient storage of eggs. The specific working principle is as follows: The base 10 has an ice box 11 and a circulating fan built in. The ice provides a cold source, and the circulating fan sends cold air evenly into the device through the air vent 13 to form a stable low-temperature environment. The battery in the battery compartment 12 powers the circulating fan to maintain continuous cooling, delay the spoilage of eggs and extend their shelf life. Loosen the latches 42 between the top cover 40 and the side panel, manually rotate the top handle 51 to drive the second lead screw 502 to rotate. The second lead screw 502 drives the gear ring 501 to rotate through the differential 52. The gear ring 501 synchronously drives the gears 211 of the four folding components 21 to rotate. The gears 211 drive the first lead screw 212 to rotate, causing the upper side panel 201 and the lower side panel 202 to fold outward, and the sides of the device are completely open. At the same time as the second lead screw 502 rotates, the upper egg tray 31 is lifted upward along the guide rod 504, and the distance between it and the lower egg tray 30 increases, automatically releasing the clamp on the egg. The differential 52 ensures that the folding speed of the side panel matches the lifting speed of the egg tray, and the actions are synchronized. Rotating the handle 51 in the opposite direction reverses the lead screw 502, causing the gear ring 501 and folding assembly 21 to reset. The side plate retracts inward, restoring the closed rectangular frame state. The upper egg tray 31 descends synchronously, cooperating with the arc-shaped receiving groove of the lower egg tray 30 to stably clamp and separate the eggs. Fastening the buckle 42 locks the top cover 40 and the side plate, completing the device closure. During transportation, the eggs will not shake or break.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
