Description

Technical Field

[0001] The present invention relates to a popcorn machine, in particular to a popcorn machine with a simple structure, which can ensure safe use of the popcorn machine and avoid potential safety hazards during use, so as to improve the use experience of the popcorn machine and ensure the personal safety of users, and belongs to the technical field of popcorn machines. Background Art

[0002] As we all know, a popcorn machine is a food equipment that makes and produces popcorn. Popcorn is crispy and easy to digest, and can be used as a delicious daily snack.

[0003] Currently, there is an old-fashioned hand-cranked popcorn machine on the market, which has a low safety factor when in use. For example, the patent number is: 201920034865.8, a pressure cover connection structure and a popcorn machine, the pressure cover connection structure, including a large pressure cover bow and a small pressure cover bow, and a first hinged ear plate and a second hinged ear plate corresponding to the large pressure cover bow and the small pressure cover bow are arranged on the pot body; at least three supporting points are formed between the first hinged ear plate and the large pressure cover bow, and between the second hinged ear plate and the small pressure cover bow.

[0004] The above-mentioned cover connection structure is used to improve the sealing between the cover and the pot of the popcorn machine, but this type of popcorn machine has the following safety hazards:

[0005] 1. When temporary personnel use the popcorn machine, the uneven hand-cranking force can easily cause the mini popcorn machine to fall off the bracket, causing the pot to fall on the ground or the table, which can easily cause the pot to open by mistake and cause harm to personnel.

[0006] 2. The connection safety between the large curved bow and the small curved bow is low. Therefore, before the pot is officially opened, if the pot falls due to uncontrollable factors or the pot opening handle is accidentally touched, it is easy to cause uncontrollable pot opening and cause harm to personnel.

[0007] 3. When using a popcorn machine, if the popcorn machine is baked for too long, the pressure in the pot will be too high, which may cause damage to the pressure gauge and gasket, or even cause the pot to burst, causing harm to people.

[0008] 4. When using a popcorn machine, it is impossible to quickly grasp the sealing strength between the lid and the pot body, which makes it very difficult to turn the handle to open the pot when the pot is full of pressure, causing panic among people and posing a great safety hazard.

[0009] It can be seen that the safety and practical protection measures of existing popcorn machines on the market are poor and do not allow users to use them safely. Summary of the invention

DETAILED DESCRIPTION

[0043] Example: Figure 1-6As shown, a popcorn machine safety mechanism is applied to the connection between the pot body 1 and the pressure cover 2 to improve safety, including a first bird-beak hook 3 and a second bird-beak hook 4, the ends of the first bird-beak hook 3 and the second bird-beak hook 4 that are away from each other are respectively hinged to the pot body 1, the middle part of the first bird-beak hook 3 is connected to the pressure cover 2 through a safety connection component 5, the ends of the first bird-beak hook 3 and the second bird-beak hook 4 that are close to each other are buckled with each other, an interference portion 31 for preventing the second bird-beak hook 4 from moving is provided on the end of the first bird-beak hook 3 close to the second bird-beak hook 4, and a blocking component for preventing the second bird-beak hook 4 from rotating accidentally is provided at the hinge between the second bird-beak hook 4 and the pot body 1.

[0044] With this design, the pressure cover 2 can be connected to the first bird's beak hook 3 through the safety connection component 5, and then when the first bird's beak hook 3 rotates along the hinge between the first bird's beak hook 3 and the pot body 1, the pressure cover 2 can be driven to rotate, so that the pressure cover 2 is buckled on the pot body 1 to encapsulate the pot body 1.

[0045] In addition, the safety connection component 5 can enable the first bird's beak hook 3 to move up and down slightly around the rotating hole, thereby avoiding the potential safety hazard of being unable to open the pressure cover 2 due to excessive sealing force between the pressure cover 2 and the pot body 1.

[0046] The interference portion 31 on the first bird's beak hook 3 can be used to prevent the second bird's beak hook 4 from moving left and right, making the first bird's beak hook 3 and the second bird's beak hook 4 more firmly fastened together, avoiding the second bird's beak hook 4 from moving due to misoperation to eliminate the restriction on the first bird's beak hook 3, causing the first bird's beak hook 3 to rotate and accidentally open the pressure cover 2, thereby improving safety in use.

[0047] In addition, the blocking component at the hinge between the second bird's beak hook 4 and the pot body 1 can be used to block the second bird's beak hook 4 from rotating, thereby preventing the second bird's beak hook 4 from rotating due to misoperation, eliminating the restriction of the second bird's beak hook 4 on the first bird's beak hook 3, and causing the first bird's beak hook 3 to rotate and accidentally open the pressure cover 2, thereby improving safety of use.

[0048] like Figure 1-2 As shown, one end of the first bird-beak hook 3 away from the second bird-beak hook 4 is hinged with a first ear plate 11 , the first ear plate 11 is integrally connected to the pot body 1 , and the first bird-beak hook 3 is hinged to the pot body 1 through the first ear plate 11 .

[0049] A second ear plate 12 is hingedly connected to one end of the second bird's beak hook 4 away from the second bird's beak hook 4 . The second ear plate 12 is integrally connected to the pot body 1 . The second bird's beak hook 4 is hingedly connected to the pot body 1 via the second ear plate 12 .

[0050] With this design, the first bird's beak hook 3 can be hinged to the pot body 1 by hingedly connecting the first bird's beak hook 3 to the first ear plate 11 , and then the first bird's beak hook 3 can rotate along the hinge between the first bird's beak hook 3 and the first ear plate 11 .

[0051] The second bird's beak hook 4 is hinged to the second ear plate 12, so that the second bird's beak hook 4 is hinged to the pot body 1, and then the second bird's beak hook 4 can rotate along the hinge between the second bird's beak hook 4 and the second ear plate 12, and the second bird's beak hook 4 can be buckled with the first bird's beak hook 3.

[0052] like Figure 1-3 As shown, the overall structure of the first bird's beak hook 3 is in a bow shape, and a first rotation hole 33 is opened at one end of the first bird's beak hook 3 close to the first ear plate 11, and a first barb portion 32 for use with the second bird's beak hook 4 is integrally provided at one end of the first bird's beak hook 3 away from the first rotation hole 33, and the interference portion 31 is arranged on the first barb portion 32.

[0053] A rotating shaft is disposed in the first rotating hole 33 , and the first bird's beak hook 3 is hinged to the first ear plate 11 via the rotating shaft in the first rotating hole 33 .

[0054] A mounting hole 34 for mounting the safety connection component 5 is provided near the middle of the first bird's beak hook 3 , and an internal thread is provided in the mounting hole 34 .

[0055] like Figure 1-3 and Figure 5 As shown, the interference portion 31 is formed by a groove opened on the first hook portion 32, and the interference portion 31 is formed on both sides of the groove.

[0056] The depth L of the interference portion 31 is 1-1.5 mm.

[0057] like Figure 1-2 and Figure 4 As shown, the second bird's beak hook 4 includes a bird's beak hook base 41 , and a second barb portion 42 used in conjunction with the first barb portion 32 is integrally connected to the bird's beak hook base 41 , and the first barb portion 32 and the second barb portion 42 are buckled.

[0058] A pot-opening handle 43 is integrally connected to the bird-beak hook base 41 , and a user can hold the pot-opening handle 43 to rotate the second bird-beak hook 4 .

[0059] The bird's beak hook base 41 is provided with a second rotation hole 44 , a rotation axis is provided in the second rotation hole 44 , and the second bird's beak hook 4 is hinged to the second ear plate 12 via the rotation axis in the second rotation hole 44 .

[0060] An anti-mis-opening protrusion 45 is integrally provided on the bird's beak hook base 41 at a position close to the second ear plate 12 .

[0061] like Figure 2 , Figure 4 and Figure 6As shown, the blocking component includes a latch hole 6 opened on the second ear plate 12, a safety latch 7 is inserted into the latch hole 6, and the safety latch 7 is in contact with the anti-misopening protrusion 45 on the second bird's beak hook 4 to limit the rotation of the second bird's beak hook 4.

[0062] like Figure 1-6 As shown, the first barb portion 32 of the first bird's beak hook 3 and the second barb portion 42 of the second bird's beak hook 4 are both barb designs.

[0063] With this design, the pressure cover 2 can be pressed against the pot body 1 by the buckling of the first bird-beak hook 3 and the second bird-beak hook 4, which is convenient for use. After the second bird-beak hook 4 is hooked with the first bird-beak hook 3, it is necessary to open the pot by pulling the pot opening handle 43 of the second bird-beak hook 4. At this time, the first barb portion 32 and the second barb portion 42 are in the process of opening the pot, and the second barb portion 42 will interfere with the first barb portion 32 by 1-1.5mm, forcing the first barb portion 32 to move 1-1.5mm to the side close to the pot body 1, and then the first bird-beak hook 3 drives the pressure cover 2 to move 1-1.5mm to the side close to the pot body 1, thereby increasing the difficulty of opening the pot, avoiding accidental opening of the pot due to a slight mistaken touch of the pot opening handle 43, and thus improving safety.

[0064] In addition, the anti-mistaken-opening protrusion 45 on the second bird-beak hook 4 cooperates with the safety latch 7 on the second ear plate 12 to prevent the second bird-beak hook 4 from rotating to open the pressure cover 2. Before opening the pot, the safety latch 7 is inserted into the latch hole 6 on the second ear plate 12, and the safety latch 7 can block the anti-mistaken-opening protrusion 45 of the second bird-beak hook 4 to prevent the second bird-beak hook 4 from rotating. At this time, the user does not remove the safety latch 7. At this time, even if the pot opening handle 43 is pulled, the anti-mistaken-opening protrusion 45 will resist the safety latch 7 and cannot be pulled, thereby avoiding the phenomenon of accidentally touching the pot opening handle 43 under any circumstances, which may cause the pot to be opened accidentally, thereby improving safety and ensuring the safety of users.

[0065] like Figure 1-2 and Figure 8 As shown, the safety connection assembly 5 includes a fastening bolt 51, on which an external thread is provided. The fastening bolt 51 is threadedly connected to the mounting hole 34 on the first bird's beak hook 3 through the external thread, and the fastening bolt 51 is connected to the pressure cover 2 at one end close to the pressure cover 2.

[0066] The fastening bolt 51 is sleeved with a limiting sleeve 52 , and two ends of the limiting sleeve 52 are respectively in contact with the nut of the fastening bolt 51 and the first bird's beak hook 3 .

[0067] The limiting sleeve 52 can be used to limit the moving position of the fastening bolt 51 , and further to limit the pressure of the fastening bolt 51 on the gland 2 .

[0068] When the fastening bolt 51 is rotated, the pressure cover 2 can be driven to press on the pot body 1 , and the pressure of the fastening bolt 51 on the pressure cover 2 can be adjusted by rotating the fastening bolt 51 .

[0069] When the fastening bolt 51 is rotated, the fastening bolt 51 drives the pressure cover 2 to press on the pot body 1, and the fastening bolt 51 applies a reverse force to the first bird's beak hook 3, so that the first bird's beak hook 3 can move slightly upward or downward around the axis of the first rotating hole 33.

[0070] The limiting sleeve 52 is arranged between the fastening bolt 51 and the first bird's beak hook 3, limiting the up and down movement distance of the first bird's beak hook 3, avoiding the phenomenon that the pressure cover 2 cannot be opened due to excessive torque on the fastening bolt 51, thereby improving safety.

[0071] When the torque on the fastening bolt 51 is too large, the first bird's beak hook 3 and the second bird's beak hook 4 will be fastened very tightly, making it very difficult to open the pot. The limiting sleeve 52 can limit the twisting depth of the fastening bolt 51, thereby avoiding excessive tightening force of the fastening bolt 51 and eliminating safety hazards.

[0072] In addition, by using the limiting sleeve 52 , the sealing strength between the sealing gasket on the gland 2 and the pot body 1 can be controlled. By adjusting the height of the limiting sleeve 52 through experiments, the sealing strength between the sealing gasket on the gland 2 and the pot body 1 can be controlled.

[0073] Therefore, when the pot body 1 is baked for a long time, the high pressure in the pot body 1 will offset the sealing force of the sealing gasket to leak and release pressure, ensuring that the pressure in the pot body 1 is maintained within a safe range, avoiding explosion caused by excessive pressure in the pot body 1, and thus improving safety.

[0074] An annular mounting groove 53 for connecting with the gland 2 is formed at one end of the fastening bolt 51 close to the gland 2 .

[0075] like Figure 1-2 and Figure 7-8 As shown, a sealing assembly for sealing the connection between the gland 2 and the pot body 1 is provided on one side of the gland 2 close to the pot body 1 , and a mounting seat 21 is integrally connected to the other side of the sealing gland 2 .

[0076] The mounting seat 21 is provided with a blind hole 22 , and the outer wall of the mounting seat 21 is threadedly connected with a tightening bolt 23 , and the tightening bolt 23 extends into the blind hole 22 .

[0077] One end of the fastening bolt 51 close to the gland 2 is assembled in the blind hole 22 of the mounting seat 21 , and one end with the jacking bolt 23 is assembled in the annular mounting groove 53 .

[0078] With such a design, the gland 2 can be mounted on the fastening bolts 51 through the blind holes 22 of the mounting seat 21 and the tightening bolts 23 .

[0079] The sealing assembly includes a sealing gasket 24 disposed on a side of the gland 2 close to the pot body 1 , and the sealing gasket 24 is fixed by a pressing plate 25 on the gland 2 , and the pressing plate 25 is fixedly mounted on the gland 2 by bolt fasteners.

[0080] like Figure 9-15 As shown, the present invention further discloses a popcorn machine, which comprises a pot body 1, and the pot body 1 is provided with the above-mentioned popcorn machine safety mechanism.

[0081] The first ear plate 11 and the second ear plate 12 of the safety mechanism of the popcorn machine are respectively connected to the pot body 1 in one piece, and the safety mechanism of the popcorn machine can be used to open or close the inlet and outlet of the pot body 1.

[0082] A support frame assembly 8 for supporting the rotation of the pot body 1 is arranged below the pot body 1 , and a pressure gauge 9 and a rotating handle 10 are arranged at the rear end of the pot body 1 .

[0083] like Fig. 9 As shown, the overall structure of the pot body 1 is in the shape of a water drop.

[0084] like Figure 13-15 As shown, a heating layer 13 is provided on the outer surface of the pot body 1 , and a plurality of thrust protrusions 14 are sequentially arranged on the heating layer 13 along the circumference of the pot body 1 , and the thrust protrusions 14 are respectively arranged along the axial direction of the pot body 1 .

[0085] The cross-section of the thrust protrusion 14 is in the shape of a right triangle, and the vertical surface of the thrust protrusion 14 is a thrust surface 15 .

[0086] With such a design, when the flame below the pot body 1 acts on the pot body 1, the flame acts on the thrust protrusion 14 of the heating layer 13. At this time, the thrust generated by the flame can act on the thrust surface 15, and then the flame can push the pot body 1 to rotate.

[0087] Furthermore, the thrust protrusion 14 can be used to increase the effective area of ​​the flame, thereby increasing the heating speed of the pot body 1, and thus speeding up the processing efficiency of the popcorn.

[0088] like Figure 10-12 As shown, the support frame assembly 8 includes a support frame 81 , on which two bearing groups for supporting the rotation of the pot body 1 are arranged, and each bearing group includes two bearings 82 .

[0089] The support frame 81 is provided with an offside stopper 83 for preventing the popcorn machine from falling on the support frame assembly 8 , and the offside stopper 83 is in contact with the limiting sleeve 52 .

[0090] The popcorn machine is rotatably mounted on the support frame assembly 8 .

[0091] The design is as follows: the popcorn machine can be rotatably arranged on the support frame assembly 8, and then can be used by manually rotating the rotating handle 10.

[0092] When the rotating handle 10 is manually turned, the popcorn machine can easily fall off the support frame assembly 8 due to uneven force. After repeated use, it is found that when the force is uneven, the mini popcorn machine can easily use the bearing 82 near the rotating handle 10 as a fulcrum, causing one end of the mini popcorn machine to jump greatly, thereby causing the popcorn machine to fall off the groove on the support frame assembly 8, and eventually causing the pot body 1 to fall directly on the ground or the table. The present invention can be used to limit the popcorn machine from jumping on the support frame assembly 8 by adding an offside stopper 83 to the support frame 81, and the offside stopper 83 can prevent the pot body 1 from falling directly on the ground or the table, thereby greatly improving safety.

[0093] For those skilled in the art, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
