Description

Technical Field

[0001] The invention belongs to the technical field of soft-boiled egg preparation, in particular to a soft-boiled egg preparation device and a preparation method. Background Art

[0002] Eggs are eggs laid by hens. They are rich in cholesterol and are a good source of high-quality protein. They can also provide a certain amount of fat and minerals and have the effect of protecting the liver. The most common way to cook eggs is to boil them in water, that is, boil them in water without breaking the shell, which can fully retain the nutrition of the eggs. Boiled eggs can be divided into soft-boiled eggs and golden sand eggs according to the time and temperature. A soft-boiled egg refers to a state in which the egg white is cooked and coagulated, while the egg yolk is cooked but not fully coagulated. As an egg with denatured egg white and partially fluid yolk, a soft-boiled egg is more likely to make people want to eat and buy it, for those who pay special attention to taste and appearance. By controlling the cooking time and temperature, the soft-boiled egg can be easily achieved. The existing egg boilers on the market are usually composed of a heating element, an insulation layer, a control circuit and other parts. The working principle is that the heating element heats water to a set temperature to form water vapor, and then transfers the heat to the egg through the holes in the egg barrier to cook it. The control circuit of the egg boiler generally includes a thermostat and a timer. The thermostat is responsible for adjusting the temperature of the heating element to keep the water temperature suitable, and the timer sets the egg boiling time to ensure that the hardness of the yolk and egg white is moderate.

[0003] However, when egg food processing companies produce soft-boiled eggs, a large amount of hot steam will be generated during the preparation of the soft-boiled eggs. No matter what kind of equipment is used, when the cooked eggs need to be taken out of the container, they may be scalded by the high-temperature steam, which will cause certain safety hazards. Therefore, under normal circumstances, after the soft-boiled eggs are made, it is necessary to wait for a while and wait for the high-temperature steam inside the egg cooker to condense before taking out the soft-boiled eggs. However, if the soft-boiled eggs are kept in a high-temperature steam environment for a long time, the fluid yolk may mature and become a golden sand egg.

[0004] To this end, the present invention provides a soft-boiled egg preparation device and a preparation method. Summary of the invention

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0021] like Figures 1 to 6 As shown, a soft-boiled egg preparation device according to an embodiment of the present invention comprises: Egg-boiling vessel 2; A receiving rack 4 is arranged in the egg-boiling container 2 and is used to hold eggs; A fixing plate 7 is inserted into the bottom of the egg-boiling container 2, and the fixing plate 7 is in contact with the side wall of the egg-boiling container 2; a fixing column 5 is threadedly connected to the center of the fixing plate 7, and the receiving frame 4 is sleeved on the fixing column 5; The receiving frame 4 includes a receiving plate 401 and a cone column 403. The cone column 403 is fixedly connected to the receiving plate 401 and is hollow inside. The fixing column 5 passes through the cone column 403. A spring buckle 503 is provided on the top of the fixing column 5 , and the spring buckle 503 is engaged with the cone column 403 to fix the cone column 403 .

[0022] When egg food processing enterprises produce soft-boiled eggs, a large amount of hot steam is generated during the preparation of soft-boiled eggs. No matter what kind of equipment is used, when the cooked eggs in the container need to be taken out, they may be scalded by the high-temperature steam, thereby causing certain safety hazards. In view of the above problems, when the preparation device provided by the present invention is used, the eggs are washed and placed on the receiving frame 4, and then the receiving frame 4 is pressed into the egg-boiling container 2, so that the cone column 403 is sleeved on the fixing column 5 to fix the receiving frame 4, and the spring buckle 503 on the top of the fixing column 5 is used to ensure the stability of the receiving frame 4 in the egg-boiling container 2 before the soft-boiled eggs are made, wherein the cone column 403 is made of high-temperature resistant plastic material, and the receiving plate 401 is made of metal material, and the cone column 403 and the receiving plate 401 are fixed by screws; It is worth noting that when making soft-boiled eggs, since the egg-boiling time is short and the eggs need to be taken out immediately after the egg-boiling time is over, otherwise the yolk of the soft-boiled egg will be ripened due to the influence of the water temperature. In one embodiment of the present invention, the fixing plate 7 is installed at the bottom of the egg-boiling vessel 2, and the fixing column 5 is fixed at the center of the fixing plate 7. Then, a sufficient amount of cold water is poured into the egg-boiling vessel 2, and the water is heated until it just bubbles (there is no large amount of steam). At this time, the receiving rack 4 holding the eggs is placed in the egg-boiling vessel 2, so that the fixing column 5 is fixed at the center of the fixing plate 7. The column 5 passes through the conical column 403. During the process of the fixed column 5 passing through the conical column 403, the spring buckle 503 on the top of the fixed column 5 is engaged with the conical column 403 to fix the receiving frame 4 on the fixed column 5, thereby fixing the receiving frame 4 and ensuring that the egg is submerged in water, so that the receiving frame 4 remains stable during the preparation of the soft-boiled egg. After boiling for 5-6 minutes, the receiving frame 4 is separated from the fixed column 5, and a soft-boiled egg is obtained after cooling, thereby avoiding the soft-boiled egg being in a high-temperature steam environment for a long time, which causes the yolk of the soft-boiled egg to mature.

[0023] like Figures 1 to 4 , Figure 7 As shown, the receiving plate 401 is provided with a plurality of holes 402 for containing eggs; a snap ring 407 is provided on the inner side of the top of the cone column 403 , and the spring buckle 503 is snap-fitted with the snap ring 407 .

[0024] In order to allow the boiling water in the egg-boiling vessel 2 to pass through the receiving plate 401 and contact the eggs on the receiving plate 401, in one embodiment of the present invention, a leak hole 402 is provided on the receiving plate 401 to allow the boiling water to pass through, so that the eggs can be boiled and the production of soft-boiled eggs can be accelerated. At the same time, when the fixing column 5 cooperates with the conical column 403, the spring buckle 503 on the fixing column 5 contacts the snap ring 407 from bottom to top, first contracts and then releases, and then forms a snap-fitting relationship with the snap ring 407 on the conical column 403, so that the conical column 403 and the receiving frame 4 can be fixed, so that the eggs are always immersed in water during the production process of soft-boiled eggs and remain relatively stable. The outer end of the spring buckle 503 is provided with a rounded corner, and the inner edge of the clamping ring 407 is also provided with a rounded corner. Under the action of an external force, the receiving frame 4 can be separated from the fixing column 5.

[0025] like Figure 5 As shown, a plurality of support blocks are welded on the inner side surface of the bottom of the conical column 403 , and a clamping claw 406 is rotatably connected to the support block; the clamping claw 406 is used to tightly fix the column 5 .

[0026] When the receiving frame 4 is sleeved on the fixing column 5 from top to bottom, in order to quickly complete the cooperation between the receiving frame 4 and the fixing column 5, in one embodiment of the present invention, the bottom opening size of the cone column 403 is much larger than the top outer circumference of the fixing column 5, so that the cone column 403 can be easily sleeved on the fixing column 5, and when the fixing column 5 penetrates to the top of the cone column 403, the circumference of the cone column 403 is continuously reduced until it is close to the outer circumference of the fixing 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 fixing column 5 penetrates the cone column 403, it slides with the clamping claw 406, and the clamping claw 406 is constrained by a torsion spring and deflected outwardly under the squeezing action of the fixing column 5. Then, under the action of the torsion spring, the clamping claw 406 clamps the side of the fixing column 5, so that the bottom of the cone column 403 can be stably sleeved on the outside of the fixing column 5, and no shaking will occur without the squeezing action of external force; During specific use, when the receiving frame 4 is sleeved on the fixed column 5, the fixed column 5 enters from the bottom of the conical column 403, and then the top of the fixed column 5 contacts the clamping jaw 406 and squeezes the clamping jaw 406 to deflect outward. As the fixed column 5 continues to penetrate the conical column 403 upward, the spring buckle 503 forms a snap-fitting relationship with the conical column 403. At this time, let go, and the receiving frame 4 is naturally sleeved on the outside of the fixed column 5, and the clamping jaw 406 clamps the fixed column 5 under the action of the torsion spring to maintain the stability of the bottom of the conical column 403.

[0027] like Figure 5 , Figure 7 As shown, a top partition plate 404 is fixedly connected to the top of the receiving plate 401 , and metal hanging rings 405 are rotatably connected to both ends of the top partition plate 404 .

[0028] In order to facilitate the removal of the receiving frame 4 as a whole after the steam is discharged, in one embodiment of the present invention, a top partition plate 404 and a metal hanging ring 405 are set on the top of the receiving plate 401. The metal hanging ring 405 can be used to pull the receiving frame 4 upward and separate it from the fixing column 5.

[0029] like Figure 6 , Figure 8 , Fig. 9As shown, the fixed column 5 includes a vertical rod 501, and a plurality of grooves are opened on the side wall of the vertical rod 501, and a driving arm 502 is rotatably connected in the groove; a second spring 6 is sleeved on the bottom of the vertical rod 501, and the second spring 6 is arranged between the driving arm 502 and the fixed plate 7.

[0030] When the receiving frame 4 is sleeved on the fixed column 5, it is impossible to ensure that the receiving frame 4 is level. The tilted receiving frame 4 will cause the eggs placed on it to move (pile up). In order to prevent the center of gravity of the receiving frame 4 from deviating to one side due to the movement of the eggs, thereby affecting the stability of the receiving frame 4, in one embodiment of the present invention, a driving arm 502 is arranged on the side wall of the vertical pole 501. When the receiving frame 4 is sleeved on the vertical pole 501, the driving arm 502 will be synchronously squeezed to deflect outward and will always be at the bottom of the receiving frame 4. The driving arm 502 that deflects with the receiving frame 4 is used to ensure the stability of the receiving frame 4 when it is sleeved on the fixed column 5. In conjunction with the second spring 6 at the bottom of the vertical pole 501, a buffering effect can be produced on the deflection of the driving arm 502, that is, the displacement of the receiving frame 4, so that the receiving frame 4 remains stable during the placement process.

[0031] When the receiving frame 4 is sleeved on the fixing column 5, the bottom of the receiving frame 4 contacts the driving arm 502 and causes the driving arm 502 to deflect. The deflection of the driving arm 502 squeezes the second spring 6 at the bottom of the vertical pole 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 vertical pole 501, the second spring 6 at the bottom of the receiving frame 4 is in a compressed state. It should be noted that when installing the receiving frame 4, the user needs to press down hard to make it fit on the fixing column 5. The receiving frame 4 will compress the second spring 6, and the elastic force of the compressed second spring 6 is greater than the total gravity of the receiving frame 4 and the eggs placed thereon; in addition, when the receiving frame 4 is fitted on the fixing column 5, the spring buckle 503 is used to form an abutment relationship with the retaining ring 407 to prevent the second spring 6 from resetting and driving the receiving frame 4 to move upward. Embodiment 2

[0032] like Figure 6 , Figure 8 , Fig. 9 As shown, it also includes a driving handle 3; the driving handle 3 includes a contact plate 301; a first tube body 302 is fixedly connected to the bottom of the contact plate 301; a second tube body 305 is provided at the bottom of the first tube body 302, and a middle partition plate 304 is fixedly connected to the outer side of the junction of the first tube body 302 and the second tube body 305; a rounded corner is provided at the bottom end of the second tube body 305 for squeezing the spring buckle 503 to contract; the second tube body 305 is slidably matched with the cone column 403, and the outer circumference of the second tube body 305 is smaller than the inner circumference of the retaining ring 407.

[0033] In order to facilitate batch production of eggs, in one embodiment of the present invention, the contact plate 301 on the driving handle 3 is located outside the egg-boiling container 2, and the second tube 305 at the bottom of the contact plate 301 is located inside the egg-boiling container 2. After the soft-boiled eggs are made, the contact plate 301 can be pressed to move the first tube 302 and the second tube 305 downward. The second tube 305 moves downward and is plugged into the top of the cone column 403, and the top of the vertical rod 501 is inserted into the second tube 305, so that the spring buckle 503 is also retracted. The cone column 403 is retracted in the vertical rod 501. At this time, the spring buckle 503 no longer has a limiting effect on the cone column 403. Under the action of the second spring 6, the cone column 403 can slide upward along the outer side of the second tube body 305 and separate from the fixed column 5 until the top partition 404 of the cone column 403 contacts the middle partition 304, and 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, so as to avoid the over-ripening of the soft-boiled eggs into golden sand eggs due to soaking in boiling water for a long time or not taking out the soft-boiled eggs in time; The outer diameter of the second tube body 305 is smaller than the inner diameter of the retaining ring 407 so that the second tube body 305 can pass through the retaining ring 407 to prevent the retaining ring 407 from blocking the second tube body 305, thereby shortening the movable stroke of the receiving frame 4 after it is separated from the fixing column 5; in addition, pressing the contact plate 301 is a short-term operation, and it is not necessary to press the contact plate 301 all the time.

[0034] Specifically, when in use, the contact plate 301 is pressed, so that the contact plate 301 drives the first tube body 302 and the second tube body 305 to move downward. When the second tube body 305 moves downward, the top of the vertical rod 501 penetrates into the second tube body 305, and the spring buckle 503 shrinks in the vertical rod 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 vertical rod 501 can squeeze the driving arm 502 to lift up, and drive the receiving frame 4 to move upward together, so that the cone column 403 slides in the second tube body 3 05, and then the top partition 404 on the top of the cone column 403 will squeeze the middle partition 304 and drive the middle partition 304 to move upward together. At this time, the receiving rack 4 is separated from the boiling water, and the production of soft-boiled eggs is completed. In order to achieve batch egg production, multiple egg-boiling vessels can be arranged in a distributed manner, and multiple egg-boiling vessels form an egg-boiling group. At the same time, after the soft-boiled eggs are prepared, a pneumatic hydraulic rod can be installed on the top of the multiple egg-boiling vessels, and the pneumatic hydraulic rod can be used to press the contact plate 301, so as to achieve the purpose of separating the receiving rack 4 from the boiling water.

[0035] like Figures 8 to 9 As shown, a first spring 306 is fixedly connected to the inner top of the first tube body 302, and a ejector pin 307 is fixedly connected to the bottom of the first spring 306; the ejector pin 307 is slidably connected to the inside of the first tube body 302 and the second tube body 305, and the bottom of the ejector pin 307 contacts the top of the fixing column 5.

[0036] In one embodiment of the present invention, a cavity is provided inside the first tube body 302 and the second tube body 305, and a first spring 306 is provided at the top of the cavity. The first spring 306 is used to connect a thimble 307 that slides at the bottom inside the first tube body 302 and the second tube body 305. The thimble 307 contacts the vertical rod 501 first, and under the pressure of the vertical rod 501, the first tube body 302, the second tube body 305 and the contact plate 301 will move upward to prevent the second tube body 305 from squeezing the spring buckle 503 at the top of the vertical rod 501, thereby causing the receiving frame 4 to be separated from the fixed column 5 in advance, resulting in a prolonged production time of the soft-boiled egg. Specifically, when in use, the bottom of the ejector pin 307 contacts the top of the vertical rod 501 and is limited. At the same time, under the action of pressure, the ejector pin 307 shrinks upward in the cavity inside the first tube body 302 and the second tube body 305 .

[0037] 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 , and larger than the circumference of the top of the fixing column 5 and the outer circumference of the second tube body 305 .

[0038] In one embodiment of the present invention, the circumference of the top opening of the conical 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, and the circumference of the top opening of the conical column 403 is larger than the circumference of the top of the fixed column 5 so that the fixed column 5 can pass through the conical column 403; the circumference of the top opening of the conical column 403 is larger than the outer circumference of the second tube body 305 so that the second tube body 305 can pass through the top opening of the conical column 403 and squeeze the spring buckle 503 to shrink in the vertical pole 501. Embodiment 3

[0039] like Figure 1 to Figure 2 As shown, an egg-laying opening 201 is provided on one side of the egg-boiling container 2; a movable plate 408 is provided on one side of the receiving frame 4 corresponding to the egg-laying opening 201; In the process of mass production of soft-boiled eggs by an enterprise, in addition to preventing the soft-boiled eggs from being over-cooked and preventing the staff from being scalded, after the receiving rack 4 is lifted, the cooked soft-boiled eggs can be transferred in combination with the conveyor belt adjacent to the egg-boiling vessel 2; in one embodiment of the present invention, when the soft-boiled eggs are lifted with the receiving rack 4 to achieve separation from the boiling water, a stop block can be selectively provided on the inner side wall of the egg-boiling vessel 2, and two of the stop blocks are provided, and the arrangement of one of the stop blocks is The position is higher than the other stop block. Specifically, the arrangement position of the stop block away from the egg laying opening 201 is higher than the other stop block. Based on this, when the receiving frame 4 is lifted upward, the center of gravity of the receiving frame can be shifted through the limitation of the stop block, so that the movable plate 408 on the receiving frame 4 can be overlapped on the egg laying opening 201, and the two stop blocks are cooperated to make the receiving frame 4 tilted. Under the action of gravity, the prepared soft-boiled eggs are transferred from the egg laying opening 201 to the conveyor belt adjacent to the egg boiling container 2.

[0040] A method for preparing a soft-boiled egg, the method comprising the following steps: S1: First, assemble the egg-boiling vessel 2, the fixing plate 7, and the fixing column 5, and pour sufficient cold water into the egg-boiling vessel 2; S2: After the water is heated to bubbles, the receiving rack 4 containing the eggs is placed into the egg-boiling container 2, and the fixing column 5 passes through the cone column 403; S3: 5-6 minutes; S4: After the timing is over, the driving handle 3 is pressed, and the driving handle 3 is raised and waits for one minute; S5: The soft-boiled egg is ready.

[0041] Working principle: When the preparation device provided by the present invention is used, the eggs are washed and placed on the receiving frame 4, and then the receiving frame 4 is pressed into the egg-boiling container 2, so that the cone column 403 is sleeved on the fixing column 5 to fix the receiving frame 4, and the spring buckle 503 on the top of the fixing column 5 is used to ensure the stability of the receiving frame 4 in the egg-boiling container 2 before the soft-boiled eggs are made, wherein the cone column 403 is made of high-temperature resistant plastic material, and the receiving plate 401 is made of metal material, and the cone column 403 and the receiving plate 401 are fixed by screws; It is worth noting that when making soft-boiled eggs, since the egg-boiling time is short and the eggs need to be taken out immediately after the egg-boiling time is over, otherwise the yolk of the soft-boiled egg will be ripened due to the influence of the water temperature. In one embodiment of the present invention, the fixing plate 7 is installed at the bottom of the egg-boiling vessel 2, and the fixing column 5 is fixed at the center of the fixing plate 7. Then, a sufficient amount of cold water is poured into the egg-boiling vessel 2, and the water is heated until it just bubbles (there is no large amount of steam). At this time, the receiving rack 4 holding the eggs is placed in the egg-boiling vessel 2, so that the fixing column 5 is fixed at the center of the fixing plate 7. The column 5 passes through the conical column 403. During the process of the fixed column 5 passing through the conical column 403, the spring buckle 503 on the top of the fixed column 5 is engaged with the conical column 403 to fix the receiving frame 4 on the fixed column 5, thereby fixing the receiving frame 4 and ensuring that the egg is submerged in water, so that the receiving frame 4 remains stable during the preparation of the soft-boiled egg. After boiling for 5-6 minutes, the receiving frame 4 is separated from the fixed column 5, and a soft-boiled egg is obtained after cooling, thereby avoiding the soft-boiled egg being in a high-temperature steam environment for a long time, which causes the yolk of the soft-boiled egg to mature.

[0042] A leak hole 402 is provided on the receiving plate 401 to allow boiling water to pass through, so that the eggs can be boiled and the production of soft-boiled eggs can be accelerated. At the same time, when the fixing column 5 cooperates with the conical column 403, the spring buckle 503 on the fixing column 5 contacts the clamping ring 407 from bottom to top, and then contracts and releases, thereby forming a clamping cooperation relationship with the clamping ring 407 on the conical column 403, so that the conical column 403, that is, the receiving frame 4, can be fixed, so that it can remain stable during the production process of soft-boiled eggs. The outer end of the spring buckle 503 is provided with a rounded corner, and the inner edge of the clamping ring 407 is also provided with a rounded corner. Under the action of an external force, the receiving frame 4 can be separated from the fixing column 5.

[0043] The opening size of the bottom of the cone column 403 is much larger than the outer circumference of the top of the fixed column 5, so the cone column 403 can be easily sleeved on the fixed column 5, and when the fixed column 5 penetrates to the top of the cone column 403, the circumference of the cone column 403 is continuously reduced 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 cone column 403, it slides with the clamping claw 406, and the clamping claw 406 is constrained by a torsion spring and deflected outwardly under the squeezing action of the fixed column 5. Then, under the action of the torsion spring, the clamping claw 406 clamps the side of the fixed column 5, so that the bottom of the cone column 403 can be stably sleeved on the outside of the fixed column 5, and no shaking will occur without the squeezing action of external force. During specific use, when the receiving frame 4 is manually sleeved on the fixed column 5, the fixed column 5 enters from the bottom of the conical column 403, and then the top of the fixed column 5 contacts the clamping claw 406 and squeezes the clamping claw 406 to deflect outward. As the fixed column 5 continues to penetrate the conical column 403 upward, the spring buckle 503 forms a snap-fitting relationship with the conical column 403. At this time, let go, and the receiving frame 4 is naturally sleeved on the outside of the fixed column 5, and the clamping claw 406 clamps the fixed column 5 under the action of the torsion spring to maintain the stability of the bottom of the conical column 403.

[0044] A driving arm 502 is arranged on the side wall of the vertical pole 501. When the receiving frame 4 is sleeved on the vertical pole 501, the driving arm 502 is synchronously squeezed to deflect outwards and is always at the bottom of the receiving frame 4. The driving arm 502 deflected with the receiving frame 4 is used to ensure the stability of the receiving frame 4 when it is sleeved on the fixed column 5. In conjunction with the second spring 6 at the bottom of the vertical pole 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 the placement process. During specific use, when the receiving frame 4 is manually sleeved on the fixing column 5, the bottom of the receiving frame 4 contacts the driving arm 502 and causes the driving arm 502 to deflect. The deflection of the driving arm 502 will squeeze the second spring 6 at the bottom of the vertical pole 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 vertical pole 501, the second spring 6 at the bottom of the receiving frame 4 is in a compressed state.

[0045] The outer diameter of the second tube body 305 is smaller than the inner diameter of the retaining ring 407 so that the second tube body 305 can pass through the retaining ring 407 to prevent the retaining ring 407 from blocking the second tube body 305, thereby shortening the movable stroke of the receiving frame 4 after it is separated from the fixing 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 all the time.

[0046] Specifically, when in use, the bottom of the ejector pin 307 contacts the top of the vertical rod 501 and is limited. At the same time, under the action of pressure, the ejector pin 307 contracts upward in the cavity inside the first tube body 302 and the second tube body 305. Therefore, the first spring 306 will not be compressed, and the first tube body 302, the second tube body 305 and the contact plate 301 will slide upward for a certain distance.

[0047] After the soft-boiled egg is made, the contact plate 301 can be pressed to make the first tube body 302 and the second tube body 305 move downward, and the second tube body 305 moves downward and is plugged into the top of the cone column 403, and the top of the vertical rod 501 is inserted into the second tube body 305, so that the spring buckle 503 is also contracted in the vertical rod 501. At this time, the spring buckle 503 no longer has a limiting effect on the cone column 403. Under the action of the second spring 6, the cone column 403 can slide upward along the outer side of the second tube body 305 and break away from the fixed column 5 until the top partition plate 404 of the cone column 403 contacts the middle partition plate 304, and under the action of the second spring 6, the middle partition plate 304 is squeezed and moved upward together, so that the first tube body 302 is lifted. At this time, the receiving frame 4 is separated from the boiling water to avoid the over-ripening of the soft-boiled egg into a golden sand egg due to soaking in boiling water for a long time or not taking out the soft-boiled egg in time; Specifically, the contact plate 301 is pressed manually, so that the contact plate 301 drives the first tube body 302 and the second tube body 305 to move downward. When the second tube body 305 moves downward, the top of the vertical rod 501 penetrates into the second tube body 305, and the spring buckle 503 shrinks in the vertical rod 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 vertical rod 501 can squeeze the driving arm 502 to lift, and drive the receiving frame 4 to move upward together, so that the cone column 403 slides on the outside of the second tube body 305, and then the top partition 404 on the top of the cone column 403 squeezes the middle partition 304, and drives the middle partition 304 to move upward together. At this time, the receiving frame 4 is separated from the boiling water, and the receiving frame 4 is taken out as a whole and placed in cold water for cooling, thereby completing the production of soft-boiled eggs.

[0048] In addition, a cavity is set inside the first tube body 302 and the second tube body 305, and a first spring 306 is set on the top of the cavity. The first spring 306 is used to connect the bottom of the ejector pin 307 sliding in the first tube body 302 and the second tube body 305. The ejector pin 307 preferentially contacts the vertical rod 501, and under the squeezing of the vertical rod 501, the first tube body 302, the second tube body 305 and the contact plate 301 will move upward. After the first tube body 302 is lifted, the second tube body 305 is prevented from squeezing the spring buckle 503 on the top of the vertical rod 501, which may cause the receiving frame 4 to detach from the fixed column 5 in advance, thereby prolonging the production time of the soft-boiled egg.
