Technical Field
[0001] This invention belongs to the field of soft-boiled egg preparation technology, specifically a soft-boiled egg preparation device and preparation method. Background Technology
[0002] Eggs are the eggs laid by hens. They are rich in cholesterol, a good source of high-quality protein, and also provide some fat and minerals. They have the effect of protecting the liver. The most common way to cook eggs is by boiling, which means boiling them without breaking the shell. This can fully preserve the nutrients in the eggs. Boiled eggs can be divided into soft-boiled eggs and golden-sand eggs depending on the time and temperature.
[0003] A soft-boiled egg is an egg where the egg white is cooked and solidified, while the yolk is not fully cooked. As an egg with denatured egg white and a partially runny yolk, a soft-boiled egg is more appealing to those who value texture and appearance, making it more attractive to eat and purchase. Achieving this soft-boiled state is relatively easy by controlling the cooking time and temperature. Commercially available egg cookers typically consist of a heating element, an insulation layer, and a control circuit. Their working principle is that the heating element heats water to a set temperature, creating steam, which is then transferred to the egg through holes in the egg separator, cooking it. The control circuit of an egg cooker generally includes a thermostat and a timer. The thermostat regulates the temperature of the heating element to maintain a suitable water temperature, while the timer sets the cooking time to ensure the yolk and egg white have the right firmness.
[0004] However, when egg processing companies produce soft-boiled eggs, a large amount of hot steam is generated during the process. Regardless of the equipment used, there is a risk of burns from the high-temperature steam when removing the cooked eggs from the container, posing a safety hazard. Therefore, it is generally necessary to wait for a period of time after the soft-boiled eggs are made, allowing the high-temperature steam inside the egg cooker to condense before removing them. However, if the cooked soft-boiled eggs are kept in a high-temperature steam environment for a long time, the runny yolk may cook and turn into a golden yolk.
[0005] Therefore, the present invention provides a soft-boiled egg preparation apparatus and preparation method. Summary of the Invention

[0017] Preferably, it further includes a drive handle, the drive handle including a contact plate; a first tube is fixedly connected to the bottom of the contact plate, and the first tube is slidably connected to the center of the pot lid; a second tube is provided at the bottom of the first tube, and a partition plate is fixedly connected to the outer side of the junction of the first tube and the second tube; the bottom end of the second tube is provided with a rounded corner for squeezing the spring buckle to retract; the second tube slides with the conical column, and the outer circumference of the second tube is smaller than the inner circumference of the retaining ring.
[0018] Preferably, a first spring is fixedly connected to the inner top of the first tube, and a pin is fixedly connected to the bottom of the first spring; the pin is slidably connected to the inside of the first tube and the second tube, and the bottom of the pin is in contact with the top of the fixed post.
[0019] Preferably, the circumference of the top opening of the conical column is smaller than the outer circumference of the middle partition plate, but larger than the circumference of the top of the fixed column and the outer circumference of the second tube.
[0020] Preferably, the egg-cooking vessel has an egg-feeding opening on one side; the receiving rack has a movable plate on the side corresponding to the egg-feeding opening.
[0021] A method for preparing soft-boiled eggs, the method comprising the following steps:
[0022] S1: First, assemble the egg cooking vessel, fixing plate, and fixing column, and pour enough cold water into the egg cooking vessel;
[0023] S2: After heating the water to a bubbling state, place the egg-holding rack into the egg-cooking vessel and ensure that the fixing post passes through the conical post;
[0024] S3: Timer for 5-6 minutes;
[0025] S4: After the timer ends, press the drive lever and wait one minute after the drive lever rises;
[0026] S5: The soft-boiled eggs are ready.
[0027] The beneficial effects of this invention are as follows:
[0028] 1. The present invention discloses a soft-boiled egg preparation device and method, wherein a receiving rack holding an egg is placed in an egg-cooking vessel, and a fixing column penetrates a conical column. During the penetration of the fixing column through the conical column, a spring buckle at the top of the fixing column engages with the conical column to fix the receiving rack on the fixing column, thereby achieving the fixation of the receiving rack and ensuring that the egg is submerged in water, so that the receiving rack remains stable during the soft-boiled egg preparation process. After boiling for one minute, the receiving rack is separated from the fixing column. After cooling, a soft-boiled egg is obtained. This method avoids the soft-boiled egg being in a high-temperature steam environment for a long time, which would cause the yolk of the soft-boiled egg to become overcooked.
[0029] 2. The soft-boiled egg preparation device and method of the present invention, by setting a driving arm on the side wall of the upright, when the receiving frame is sleeved on the upright, the driving arm will be squeezed outward and always at the bottom of the receiving frame. The driving arm that deflects with the receiving frame ensures the stability of the receiving frame when it is sleeved on the fixed column. In conjunction with the second spring at the bottom of the upright, the deflection of the driving arm, that is, the displacement of the receiving frame, can produce a buffering effect, so that the receiving frame remains stable during placement.
[0030] 3. The soft-boiled egg preparation device and method of the present invention, after the soft-boiled egg is made, can be pressed to make the first tube and the second tube move downwards. The second tube moves downwards and is inserted into the top of the cone column, while the top of the upright is inserted into the second tube, so that the spring buckle also retracts into the upright. At this time, the spring buckle no longer has a limiting effect on the cone column. Under the action of the second spring, the cone column can slide upwards along the outside of the second tube and get away from the fixed column until the top partition of the cone column contacts the middle partition. Under the action of the second spring, the middle partition is squeezed and moved upwards together, so that the first tube is raised. At this time, the receiving frame is separated from the boiling water, avoiding the soft-boiled egg from being overcooked into a golden sand egg due to prolonged soaking in boiling water or failure to remove the soft-boiled egg in time.

[0042] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example 1
[0043] like Figures 1 to 6 As shown in the embodiment of the present invention, a soft-boiled egg preparation apparatus includes:
[0044] Egg boiling dish 2;
[0045] The receiving rack 4, which is set inside the egg cooking vessel 2, is used to hold the eggs;
[0046] A fixing plate 7 is inserted into the bottom of the egg cooking vessel 2, and the fixing plate 7 is attached to the side wall of the egg cooking vessel 2; a fixing post 5 is threadedly connected to the center of the fixing plate 7, and the support frame 4 is sleeved on the fixing post 5.
[0047] The receiving frame 4 includes a receiving plate 401 and a conical column 403. The conical column 403 is fixedly connected to the receiving plate 401, and the interior of the conical column 403 is hollow. The fixing column 5 passes through the conical column 403.
[0048] The top of the fixing column 5 is provided with a spring buckle 503, and the spring buckle 503 is engaged with the cone column 403 to fix the cone column 403.
[0049] When producing soft-boiled eggs in egg processing enterprises, a large amount of hot steam is generated during the preparation process. Regardless of the equipment used, there is a risk of burns from the high-temperature steam when removing the cooked eggs from the container, posing a certain safety hazard. To address this issue, the preparation device provided by this invention involves washing the eggs and placing them on the receiving rack 4. The receiving rack 4 is then pressed into the egg-cooking container 2, with the conical column 403 fitted onto the fixing column 5 to secure the receiving rack 4. The spring buckle 503 at the top of the fixing column 5 ensures the stability of the receiving rack 4 within the egg-cooking container 2 before the soft-boiled eggs are fully cooked. The conical column 403 is made of high-temperature resistant plastic, while the receiving plate 401 is made of metal, and the conical column 403 and the receiving plate 401 are fixed together with screws.
[0050] It is worth noting that when making soft-boiled eggs, the boiling time is relatively short, and the eggs need to be removed immediately after boiling, otherwise the yolks will become overcooked due to the influence of water temperature. In one embodiment of the present invention, a fixing plate 7 is installed at the bottom of the egg-cooking vessel 2, and a fixing post 5 is fixed in the center of the fixing plate 7. Sufficient cold water is then poured into the egg-cooking vessel 2 and heated until it just begins to bubble (without a large amount of steam). At this point, the receiving rack 4, which holds the eggs, is placed into the egg-cooking vessel 2, thus securing the eggs. The column 5 penetrates the cone column 403. During the process of fixing the column 5 through the cone column 403, the spring buckle 503 at the top of the fixing column 5 engages with the cone column 403 to fix the receiving frame 4 on the fixing column 5. This achieves the fixation of the receiving frame 4 and ensures that the egg is submerged in water, so that the receiving frame 4 remains stable during the preparation of soft-boiled eggs. After boiling for 5-6 minutes, the receiving frame 4 is separated from the fixing column 5. After cooling, the soft-boiled egg is obtained, which avoids the soft-boiled egg being in a high-temperature steam environment for a long time, which would cause the yolk of the soft-boiled egg to overcook.
[0051] like Figures 1 to 4 , Figure 7 As shown, the receiving plate 401 has multiple drainage holes 402 for holding eggs; the inner side of the top of the cone column 403 is provided with a retaining ring 407, and the spring buckle 503 is engaged with the retaining ring 407.
[0052] In order to allow boiling water in the egg-cooking vessel 2 to pass through the receiving plate 401 and come into contact with the eggs on the receiving plate 401, in one embodiment of the present invention, a drain hole 402 is provided on the receiving plate 401 to allow boiling water to pass through, so as to boil the eggs and accelerate the production of soft-boiled eggs. At the same time, when the fixing column 5 cooperates with the cone column 403, the spring buckle 503 on the fixing column 5 contacts the retaining ring 407 from bottom to top, first retracts and then releases, thereby forming a snap-fit relationship with the retaining ring 407 on the cone column 403, which can realize the fixation of the cone column 403 and the receiving frame 4, so that the eggs are always submerged in water during the production of soft-boiled eggs and remain relatively stable.
[0053] The outer end of the spring buckle 503 is rounded, and the inner edge of the retaining ring 407 is also rounded. Under the action of external force, the receiving frame 4 can be separated from the fixed post 5.
[0054] like Figure 5 As shown, multiple support blocks are welded to the inner bottom surface of the cone column 403, and clamps 406 are rotatably connected to the support blocks; the clamps 406 are used to clamp the fixed column 5.
[0055] When the receiving frame 4 is fitted onto the fixed column 5 from top to bottom, in order to quickly complete the engagement between the receiving frame 4 and the fixed column 5, in one embodiment of the present invention, the bottom opening size of the conical column 403 is much larger than the top outer circumference of the fixed column 5, so that the conical column 403 can be easily fitted onto the fixed column 5. As the fixed column 5 penetrates to the top of the conical column 403, the circumference of the conical column 403 continuously decreases until it is close to the outer circumference of the fixed column 5 to prevent the receiving frame 4 from shaking. In addition, in order to further prevent the bottom of the receiving frame 4 from shaking, when the fixed column 5 penetrates the conical column 403, it engages with the clamp 406 in a sliding engagement. The clamp 406 is constrained by a torsion spring and deflects outward under the squeezing action of the fixed column 5. Then, under the action of the torsion spring, the clamp 406 clamps the side of the fixed column 5, so that the bottom of the conical column 403 can be stably fitted onto the outside of the fixed column 5 and will not shake under the action of no external squeezing force.
[0056] In practical use, when the receiving frame 4 is fitted onto the fixed column 5, the fixed column 5 enters from the bottom of the conical column 403. Then, the top of the fixed column 5 contacts the clamp 406 and squeezes the clamp 406 outward. As the fixed column 5 continues to penetrate the conical column 403 upward, the spring buckle 503 and the conical column 403 form a snap-fit relationship. At this time, when you release the hand, the receiving frame 4 naturally fits onto the outside of the fixed column 5, and the clamp 406 clamps the fixed column 5 under the action of the torsion spring, maintaining the stability of the bottom of the conical column 403.
[0057] like Figure 5 , Figure 7As shown, a top partition plate 404 is fixedly connected to the top of the receiving plate 401, and metal lifting rings 405 are rotatably connected to both ends of the top partition plate 404.
[0058] In order to facilitate the removal of the entire receiving frame 4 after steam is discharged, in one embodiment of the present invention, a top partition 404 and a metal lifting ring 405 are provided on the top of the receiving plate 401. The receiving frame 4 can be pulled upward by using the metal lifting ring 405 to separate it from the fixed column 5.
[0059] like Figure 6 , Figure 8 , Figure 9 As shown, the fixed column 5 includes a pole 501, and the side wall of the pole 501 has multiple slots, and a drive arm 502 is rotatably connected in the slots; a second spring 6 is sleeved at the bottom of the pole 501, and the second spring 6 is arranged between the drive arm 502 and the fixed plate 7.
[0060] When the receiving frame 4 is fitted onto the fixed column 5, it cannot be ensured that the receiving frame 4 is horizontal. The tilted receiving frame 4 will cause the eggs placed on it to move (pile together). In order to avoid the eggs moving and causing the center of gravity of the receiving frame 4 to shift to one side, which would affect the stability of the receiving frame 4, in one embodiment of the present invention, a driving arm 502 is provided on the side wall of the upright 501. When the receiving frame 4 is fitted onto the upright 501, the driving arm 502 will be squeezed outward and always at the bottom of the receiving frame 4. The driving arm 502, which deflects with the receiving frame 4, ensures the stability of the receiving frame 4 when it is fitted onto the fixed column 5. In conjunction with the second spring 6 at the bottom of the upright 501, the deflection of the driving arm 502, that is, the displacement of the receiving frame 4, can be buffered, so that the receiving frame 4 remains stable during placement.
[0061] In practical use, when the support frame 4 is manually attached to the fixed column 5, the bottom of the support frame 4 contacts the drive arm 502, causing the drive arm 502 to deflect. The deflection of the drive arm 502 will squeeze the second spring 6 at the bottom of the upright 501, so that the elastic potential energy generated by the compression of the second spring 6 can buffer the displacement of the support frame 4. When the support frame 4 is engaged with the spring buckle 503 at the top of the upright 501, the second spring 6 at the bottom of the support frame 4 is in a compressed state.
[0062] It should be noted that when installing the support frame 4, the user needs to press down hard to make it fit onto the fixed post 5. The support frame 4 will compress the second spring 6, and the elastic force of the second spring 6 after compression is greater than the total weight of the support frame 4 and the eggs placed on it. In addition, when the support frame 4 is fitted onto the fixed post 5, the spring buckle 503 and the retaining ring 407 form an abutment relationship to prevent the second spring 6 from resetting and causing the support frame 4 to move upward. Example 2
[0063] like Figure 6 , Figure 8 , Figure 9 As shown, it also includes a drive handle 3; the drive handle 3 includes a contact plate 301; a first tube 302 is fixedly connected to the bottom of the contact plate 301; a second tube 305 is provided at the bottom of the first tube 302, and a middle partition 304 is fixedly connected to the outer side of the junction of the first tube 302 and the second tube 305; the bottom end of the second tube 305 is provided with a rounded corner for squeezing the spring buckle 503 to retract; the second tube 305 is slidably engaged with the conical column 403, and the outer circumference of the second tube 305 is smaller than the inner circumference of the retaining ring 407.
[0064] To facilitate mass production of eggs, in one embodiment of the invention, the contact plate 301 on the drive handle 3 is located outside the egg-cooking vessel 2, while the second tube 305 at the bottom of the contact plate 301 is located inside the egg-cooking vessel 2. After the soft-boiled eggs are made, pressing the contact plate 301 causes both the first tube 302 and the second tube 305 to move downwards. The second tube 305 moves downwards and inserts into the top of the cone 403, while the top of the upright 501 is inserted into the second tube 305, causing the spring buckle 503 to retract. When retracted inside the upright 501, the spring buckle 503 no longer limits the cone 403. Under the action of the second spring 6, the cone 403 can slide upward along the outside of the second tube 305 and detach from the fixed column 5 until the top partition 404 of the cone 403 contacts the middle partition 304. Under the action of the second spring 6, the middle partition 304 is squeezed and moved upward together, so that the receiving frame 4 is separated from the boiling water, thus avoiding the soft-boiled egg from becoming overcooked and turning into a golden sand egg due to prolonged soaking in boiling water or failure to remove the soft-boiled egg in time.
[0065] The outer circumference of the second tube 305 is smaller than the inner circumference of the retaining ring 407 so that the second tube 305 can pass through the retaining ring 407, preventing the retaining ring 407 from blocking the second tube 305, which would shorten the displacement stroke of the receiving frame 4 after it is separated from the fixed column 5. In addition, pressing the contact plate 301 is a short-term operation and does not need to be pressed all the time.
[0066] In practical use, pressing the contact plate 301 causes the first tube 302 and the second tube 305 to move downwards. When the second tube 305 moves downwards, the top of the upright 501 inserts into the second tube 305, and the spring buckle 503 retracts into the upright 501. At the same time, since the spring buckle 503 no longer limits the cone column 403, the second spring 6 located at the bottom of the upright 501 can compress the drive arm 502 to lift, and drive the receiving frame 4 to move upwards together, causing the cone column 403 to slide in the second tube 302. On the outside of 05, the top partition 404 at the top of the cone 403 will then squeeze the middle partition 304 and drive the middle partition 304 to move upward together. At this time, the receiving frame 4 separates from the boiling water, completing the production of soft-boiled eggs. In order to achieve batch production, multiple egg-cooking vessels can be distributed and arranged, and multiple egg-cooking vessels form an egg-cooking group. After the soft-boiled eggs are prepared, pneumatic hydraulic rods can be installed on the top of multiple egg-cooking vessels to press the contact plate 301, thereby achieving the purpose of separating the receiving frame 4 from the boiling water.
[0067] like Figures 8 to 9 As shown, a first spring 306 is fixedly connected to the inner top of the first tube 302, and a pin 307 is fixedly connected to the bottom of the first spring 306; the pin 307 is slidably connected to the inside of the first tube 302 and the second tube 305, and the bottom of the pin 307 is in contact with the top of the fixed post 5.
[0068] In one embodiment of the present invention, cavities are provided inside the first tube 302 and the second tube 305, and a first spring 306 is provided at the top of the cavity. The first spring 306 is used to connect a push pin 307 that slides at the bottom inside the first tube 302 and the second tube 305. The push pin 307 first contacts the upright 501, and under the pressure of the upright 501, the first tube 302, the second tube 305 and the contact plate 301 will move upward to prevent the second tube 305 from pressing the spring buckle 503 at the top of the upright 501, which would cause the support frame 4 to detach from the fixed column 5 in advance, thus extending the production time of the soft-boiled egg.
[0069] In actual use, the bottom of the ejector pin 307 contacts the top of the upright 501 and is limited. At the same time, under pressure, the ejector pin 307 retracts upward into the cavity inside the first tube 302 and the second tube 305.
[0070] like Figures 8 to 9 As shown, the circumference of the top opening of the cone column 403 is smaller than the outer circumference of the middle partition 304, but larger than the top circumference of the fixed column 5 and the outer circumference of the second tube 305.
[0071] In one embodiment of the present invention, the circumference of the top opening of the cone column 403 is set to be smaller than the outer circumference of the middle partition 304 so that after the receiving frame 4 is separated from the fixed column 5, it can rely on the top partition 404 to drive the middle partition 304 to move upward synchronously. The circumference of the top opening of the cone column 403 is larger than the top circumference of the fixed column 5 so that the fixed column 5 can penetrate the cone column 403. The circumference of the top opening of the cone column 403 is larger than the outer circumference of the second tube 305 so that the second tube 305 can penetrate the top opening of the cone column 403 and compress the spring buckle 503 to retract into the upright 501. Example 3
[0072] like Figures 1 to 2 As shown, the egg-cooking vessel 2 has an egg-feeding opening 201 on one side; the receiving rack 4 has a movable plate 408 on the side corresponding to the egg-feeding opening 201.
[0073] In the process of mass-producing soft-boiled eggs in an enterprise, in addition to preventing the eggs from overcooking and avoiding burns to workers, after the receiving rack 4 is lifted, it can be combined with the conveyor belt adjacent to the egg-cooking vessel 2 to transfer the cooked soft-boiled eggs. In one embodiment of the present invention, after the soft-boiled eggs are lifted with the receiving rack 4 to separate them from the boiling water, a stop block can be selectively provided on the inner side wall of the egg-cooking vessel 2, and two stops block are provided, with one of the stops arranged in a specific manner. The position is higher than the other block. Specifically, the block that is farther away from the egg-laying opening 201 is positioned higher than the other block. Based on this, when the receiving frame 4 is lifted upward, the center of gravity of the receiving frame can be shifted by the limiting of the blocks, so that the movable plate 408 on the receiving frame 4 can overlap the egg-laying opening 201. With the help of the two blocks, the receiving frame 4 is tilted. Under the action of gravity, the prepared soft-boiled egg is transferred from the egg-laying opening 201 to the conveyor belt adjacent to the egg-cooking vessel 2.
[0074] A method for preparing soft-boiled eggs, the method comprising the following steps:
[0075] S1: First, assemble the egg cooking vessel 2, the fixing plate 7, and the fixing column 5, and pour enough cold water into the egg cooking vessel 2;
[0076] S2: After heating the water to a bubbling state, place the egg-holding rack 4 into the egg-cooking dish 2, and ensure that the fixing post 5 passes through the cone post 403;
[0077] S3: Timer for 5-6 minutes;
[0078] S4: After the timer ends, press the drive lever 3 and wait one minute after the drive lever 3 is raised;
[0079] S5: The soft-boiled eggs are ready.
[0080] Working principle: When using the preparation device provided by the present invention, the eggs are washed and placed on the receiving frame 4, and then the receiving frame 4 is pressed into the egg cooking vessel 2, so that the conical column 403 is sleeved on the fixed column 5 to fix the receiving frame 4. The spring buckle 503 at the top of the fixed column 5 ensures the stability of the receiving frame 4 in the egg cooking vessel 2 before the soft-boiled egg is made. The conical column 403 is made of high temperature resistant plastic material, while the receiving plate 401 is made of metal material, and the conical column 403 and the receiving plate 401 are fixed with screws.
[0081] It is worth noting that when making soft-boiled eggs, the boiling time is relatively short, and the eggs need to be removed immediately after boiling, otherwise the yolks will become overcooked due to the influence of water temperature. In one embodiment of the present invention, a fixing plate 7 is installed at the bottom of the egg-cooking vessel 2, and a fixing post 5 is fixed in the center of the fixing plate 7. Sufficient cold water is then poured into the egg-cooking vessel 2 and heated until it just begins to bubble (without a large amount of steam). At this point, the receiving rack 4, which holds the eggs, is placed into the egg-cooking vessel 2, thus securing the eggs. The column 5 penetrates the cone column 403. During the process of fixing the column 5 through the cone column 403, the spring buckle 503 at the top of the fixing column 5 engages with the cone column 403 to fix the receiving frame 4 on the fixing column 5. This achieves the fixation of the receiving frame 4 and ensures that the egg is submerged in water, so that the receiving frame 4 remains stable during the preparation of soft-boiled eggs. After boiling for 5-6 minutes, the receiving frame 4 is separated from the fixing column 5. After cooling, the soft-boiled egg is obtained, which avoids the soft-boiled egg being in a high-temperature steam environment for a long time, which would cause the yolk of the soft-boiled egg to overcook.
[0082] A perforation 402 is provided on the receiving plate 401 to allow boiling water to pass through, which can boil the eggs and accelerate the production of soft-boiled eggs. At the same time, when the fixing column 5 is engaged with the cone column 403, the spring buckle 503 on the fixing column 5 contacts the retaining ring 407 from bottom to top, first retracts and then releases, thereby forming a snap-fit relationship with the retaining ring 407 on the cone column 403, which can fix the cone column 403, i.e. the receiving frame 4, and keep it stable during the production of soft-boiled eggs.
[0083] The outer end of the spring buckle 503 is rounded, and the inner edge of the retaining ring 407 is also rounded. Under the action of external force, the receiving frame 4 can be separated from the fixed post 5.
[0084] The bottom opening of the conical column 403 is much larger than the top outer circumference of the fixed column 5, so that the conical column 403 can be easily fitted onto the fixed column 5. As the fixed column 5 penetrates to the top of the conical column 403, the circumference of the conical column 403 gradually decreases until it is close to the outer circumference of the fixed column 5 to prevent the support frame 4 from shaking. In addition, to further prevent the bottom of the support frame 4 from shaking, when the fixed column 5 penetrates the conical column 403, it slides into contact with the clamp 406. The clamp 406 is constrained by a torsion spring and deflects outward under the squeezing action of the fixed column 5. Then, under the action of the torsion spring, the clamp 406 clamps the side of the fixed column 5, so that the bottom of the conical column 403 can be stably fitted onto the outside of the fixed column 5 and will not shake under the action of no external squeezing force.
[0085] In practical use, when the receiving frame 4 is manually attached to the fixed column 5, the fixed column 5 enters from the bottom of the conical column 403. Then, the top of the fixed column 5 contacts the clamp 406 and squeezes the clamp 406 to deflect outward. As the fixed column 5 continues to penetrate the conical column 403 upward, the spring buckle 503 and the conical column 403 form a snap-fit relationship. At this time, when the hand is released, the receiving frame 4 is naturally attached to the outside of the fixed column 5, and the clamp 406 clamps the fixed column 5 under the action of the torsion spring, maintaining the stability of the bottom of the conical column 403.
[0086] A drive arm 502 is installed on the side wall of the upright 501. When the support frame 4 is sleeved on the upright 501, the drive arm 502 will be squeezed outward and always at the bottom of the support frame 4. The drive arm 502, which deflects with the support frame 4, ensures the stability of the support frame 4 when it is sleeved on the fixed column 5. In conjunction with the second spring 6 at the bottom of the upright 501, the deflection of the drive arm 502, i.e. the displacement of the support frame 4, can be buffered, so that the support frame 4 remains stable during placement.
[0087] In practical use, when the receiving frame 4 is manually attached to the fixed column 5, the bottom of the receiving frame 4 contacts the drive arm 502, causing the drive arm 502 to deflect. The deflection of the drive arm 502 will squeeze the second spring 6 at the bottom of the upright 501, so that the elastic potential energy generated by the compression of the second spring 6 can buffer the displacement of the receiving frame 4. When the receiving frame 4 is engaged with the spring buckle 503 at the top of the upright 501, the second spring 6 at the bottom of the receiving frame 4 is in a compressed state.
[0088] The outer circumference of the second tube 305 is smaller than the inner circumference of the retaining ring 407 so that the second tube 305 can pass through the retaining ring 407, preventing the retaining ring 407 from blocking the second tube 305, which would shorten the displacement stroke of the receiving frame 4 after it is separated from the fixed column 5. In addition, pressing the contact plate 301 is a short-term operation and does not require manual pressing of the contact plate 301 at all times.
[0089] In actual use, the bottom of the ejector pin 307 contacts the top of the upright 501 and is limited. At the same time, under pressure, the ejector pin 307 retracts upward into the cavity inside the first tube 302 and the second tube 305. Therefore, the first spring 306 will not be compressed, while the first tube 302, the second tube 305 and the contact plate 301 will slide upward for a certain distance.
[0090] After the soft-boiled egg is made, the first tube 302 and the second tube 305 can be moved downward by pressing the contact plate 301. The second tube 305 is inserted into the top of the cone 403, and the top of the upright 501 is inserted into the second tube 305, so that the spring buckle 503 is also retracted into the upright 501. At this time, the spring buckle 503 no longer has a limiting effect on the cone 403. Under the action of the second spring 6, the cone 403 can slide upward along the outside of the second tube 305 and get away from the fixed column 5 until the top partition 404 of the cone 403 contacts the middle partition 304. Under the action of the second spring 6, the middle partition 304 is squeezed and moved upward together, so that the first tube 302 is lifted. At this time, the receiving frame 4 is separated from the boiling water to avoid the soft-boiled egg from being overcooked and becoming a golden sand egg due to being soaked in boiling water for a long time or not being taken out in time.
[0091] Specifically, the contact plate 301 is pressed down, causing the first tube 302 and the second tube 305 to move downwards. When the second tube 305 moves downwards, the top of the upright 501 enters the second tube 305, and the spring buckle 503 retracts into the upright 501. At the same time, since the spring buckle 503 no longer limits the cone 403, the second spring 6 at the bottom of the upright 501 can squeeze the drive arm 502 to rise and drive the receiving frame 4 to move upwards together, so that the cone 403 slides on the outside of the second tube 305. Then, the top partition 404 at the top of the cone 403 will squeeze the middle partition 304 and drive the middle partition 304 to move upwards together. At this time, the receiving frame 4 is separated from the boiling water. The receiving frame 4 is taken out as a whole and placed in cold water to cool, thus completing the making of soft-boiled eggs.
[0092] In addition, cavities are provided inside the first tube 302 and the second tube 305, and a first spring 306 is provided at the top of the cavity. The first spring 306 is used to connect the ejector pin 307 that slides at the bottom inside the first tube 302 and the second tube 305. The ejector pin 307 first contacts the upright 501, and under the pressure of the upright 501, the first tube 302, the second tube 305 and the contact plate 301 will move upward. After the first tube 302 is raised, it prevents the second tube 305 from pressing the spring buckle 503 at the top of the upright 501, which would cause the support frame 4 to detach from the fixed column 5 in advance, thus extending the production time of the soft-boiled egg.
