Description

Technical Field

[0001] The utility model relates to an electric barbecue skewer lifting platform. Background Art

[0002] In existing electric heating barbecue skewer devices, generally, a barbecue skewer rack located below and an electric heating device (such as a light wave lamp, etc.) arranged above the barbecue skewer rack are used to heat the food skewers on the barbecue skewer rack. Although this method can cook the food skewers, the distance between the electric heating device and the food skewers is fixed. In order to adapt to different foods, the position of the heating device and the barbecue skewer rack is usually relatively far. In this way, for some food skewers that are difficult to cook thoroughly, it takes a long time and the Maillard reaction cannot occur, resulting in a deteriorated taste. Content of the Utility Model

[0008] Springs are arranged on the base corresponding to each lever. Under the action of the springs, the driving ends of the two levers can move towards each other; among them, the larger distance between the driving ends of the two levers under the action of an external force is the first distance, and the smaller distance between the driving ends of the two levers under the action of the springs is the second distance;

[0018] When the lifting device rises or falls away from the push rod, the positioning spring presses against the plate surface on one side of the positioning plate, so that the end of the touch rod on the rotating shaft close to the push rod is set at an acute angle with the push rod;

[0019] When the lifting device descends or rises to the point where one end of the touch rod is pressed by the push rod, the touch rod drives the rotating shaft to start rotating and completes a rotation of more than 90 degrees during the continued descending process.

[0020] Furthermore, the turning device comprises:

[0021] A drive shaft, one end of which is connected to the rotating shaft through a one-way transmission mechanism, and the other end of which is hingedly connected to an inverted L-shaped slider, the inverted L-shaped slider comprising a support arm and a cylindrical slider provided at the upper end of the support arm;

[0022] A flip guide rail is vertically arranged corresponding to the inverted L-shaped slider, and a flip chute adapted to the cylindrical slider is provided on the flip guide rail; the flip chute includes, from top to bottom, an upper vertical chute, an inverted Y-shaped flip chute, and a lower vertical chute; the inverted Y-shaped flip chute includes an upper inclined chute, a horizontal chute, and a lower inclined chute that are connected; the upper end of the upper inclined chute is connected to the lower end of the upper vertical chute; the lower end of the lower inclined chute is connected to the lower vertical chute;

[0023] The cylindrical slider is slidably arranged in the chute; the length of the slide plate is adapted to the length of the upper inclined chute, the horizontal chute and the lower inclined chute;

[0024] The flipping process of the inverted L-shaped slider in the flip chute includes:

[0025] 1) Straight upward: When the lifting device drives the drive shaft to move from bottom to top, the inverted L-shaped slider moves upward along the lower vertical slide groove driven by the drive shaft. At this time, the inverted L-shaped slider is located directly above the drive shaft;

[0026] 2) Flip the first 45 degrees; when the inverted L-shaped slider moves up to the lower inclined chute, the inverted L-shaped slider flips 45 degrees along the lower inclined chute;

[0027] 3) Flip a second 45 degrees; the inverted L-shaped slider flips 45 degrees along the downward inclined chute and continues to slide into the horizontal chute for a second 45-degree flip; at this time, the inverted L-shaped slider is located in the horizontal chute; the hinged end of the drive shaft is located at the intersection of the Y-shaped flip chute;

[0028] 4) Flip a third 45 degrees; as the inverted L-shaped slider continues to move upward, the hinged end of the drive shaft drives the inverted L-shaped slider to slide up the inclined chute and flip a third 45 degrees; at this point, the inverted L-shaped slider is located behind the drive shaft;

[0030] When descending, the recovery can be completed by running in reverse from step 5;

[0031] During the above-mentioned flipping process, since a one-way transmission mechanism is provided between the inverted L-shaped slider and the drive shaft, the inverted L-shaped slider will drive the drive shaft to flip simultaneously during the upward or downward movement.

[0032] Furthermore, the turning device comprises:

[0033] A lifting slide rail; a slider is slidably arranged on the lifting slide rail, and the slider slides up and down along the lifting slide rail under the action of external force;

[0034] Rail clamps are provided at both ends of the lifting slide rail;

[0035] A flip track is arranged parallel to one side of the lifting slide rail; the flip track is provided with a toothless section and a rack section;

[0036] A drive shaft frame is provided on the slider, a drive shaft is horizontally provided in the front section of the drive shaft frame, a grill mechanism is installed at the front end of the drive shaft, and a spline tooth is provided at the tail end of the drive shaft; a gear that can mesh with the rack of the rack section is provided at the tail end of the drive shaft frame; the gear shaft extends into the rear section of the drive shaft frame and is coaxially arranged with the drive shaft; a spline hole is provided at one end of the gear shaft extending into the drive shaft frame, and the spline hole of the gear shaft is sleeved on the spline teeth of the drive shaft for transmission connection;

[0039] When the grill slider rises under the action of external force, the gear corresponding to the flip track runs upward on the toothless section, and the drive shaft does not move;

[0040] When the gear moves to the rack section under the drive of the slider, the gear rotates 180 degrees under the action of the rack section and then continues to move upward;

[0041] Under the action of the slider, it continues to move upward and makes the shifting rod touch the upper rail clamping head, and then the shifting shaft mechanism shifts the gear to the side of the flip track;

[0042] When the grill slide block moves downward under the action of external force, the grill slide block continues to move downward and makes the shifting rod touch the lower pull rail clamping head, and then the shifting shaft mechanism shifts the gear to the flip track.

[0043] Furthermore, a positioning device is provided on the driving shaft so that the driving shaft can be positioned at a predetermined phase after being flipped.

[0044] Furthermore, the turning device comprises:

[0045] Guide rail: It includes a toothed rail formed by a plurality of tooth columns arranged at equal intervals in the upper vertical rail, the lower vertical rail and in the middle; among them, the trajectories of the upper vertical rail and the lower vertical rail are on the same vertical line, and the trajectory of the toothed rail is arranged in parallel and spaced from the trajectories of the upper vertical slide rail and the lower vertical slide rail;

[0046] Slider: A gear meshing with the tooth columns of the toothed rail; at the opposite ends of the gear, smooth sections adapted to the upper vertical rail and the lower vertical rail are integrally provided; thus forming a slider with relatively arranged smooth sections and relatively arranged gear sections integrated; the drive shaft is coaxially arranged with the slider; the other end of the drive shaft is connected to the skewer rack;

[0048] When the drive shaft drives the slider to rise, the smooth section of the slider leans on the lower vertical rail and slides upward;

[0049] When the slider slides upward to the toothed rail, due to the existence of the one-way passing mechanism, under the action of the wedge section, the gear section meshes with the toothed rail, the slider continues to move upward along the toothed rail and flips 180 degrees. Subsequently, the gear section disengages from the toothed rail, and the other smooth section of the slider leans on the upper vertical rail and continues to move upward;

[0050] When the drive shaft drives the slider to descend, the smooth section of the slider leans on the upper vertical rail and slides downward;

[0051] When the slider slides downward to the toothed rail, since this direction of the one-way passing mechanism is the passing state, the chute of the slider is in the open state, and the chute moves downward through the toothed rail; and after passing through the toothed rail, it continues to move downward by leaning on the lower vertical rail through the smooth section.

[0052] The utility model has the following advantages:

[0053] 1) By using the lifting device to make the food approach the upper heating device, thereby shortening the distance between the food to be grilled and the grill head. When grilling for a certain time or achieving a certain effect, the distance is increased and then decreased again, so that the surface of the meat skewer is quickly grilled "charred"; and each rise and fall just completes one flip of the skewer, so that both sides of the skewer are grilled until the outside is charred and the inside is tender. This grilling mode can better exert the effect of the "Maillard reaction" and has a better taste;

[0054] 2) The heating device is "placed above", which can prevent grease from dripping onto the grill head, reducing fumes or preventing fires;

[0055] 3) In the past, a certain distance had to be maintained. If it was too close, oil splashing could cause a fire or it was easy to get scorched. However, maintaining a certain distance often led to a very long grilling time. Therefore, we adjusted the food closer to the grilling head, lowered and flipped it after grilling for a certain period. This not only saved time, eliminated safety issues, but also enhanced the grilling effect, achieving three benefits in one go;

[0056] 4) North American power outlets generally can only withstand a heating power of no more than 2 kilowatts, which would result in a very long time and poor effect for large-sized ovens or air fryers. After adopting the lifting and flipping functions, it can be greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0080] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0081] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0082] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0083] The present utility model aims to provide an electric barbecue skewer lifting platform, and the lifting platform is a scissor-type lifting platform; the scissor-type lifting platform includes a base 1 and a tabletop, and two scissor arm groups are arranged side by side between the tabletop and the base; a driving mechanism for driving the scissor arm groups to lift is arranged on the base between the two scissor arm groups. The driving mechanism can be manual, electric, or a combination structure of manual and electric.

[0084] In addition to the bearing function, the above-mentioned tabletop also plays a role in preventing food or other things from falling into the base. Generally, a barbecue skewer rack 21 can be integrally made on the tabletop to facilitate the roasting of food. For example, side plates can be arranged on both sides of the tabletop to form a U-shaped groove; or side plates can be arranged on all four sides of the tabletop to form a box shape; at least one rotating shaft and barbecue skewers can be arranged on two opposite side plates.

[0085] Embodiment 1

[0086] As Figures 1 to 5In the illustrated embodiment, the drive mechanism is a manual and electric dual-purpose drive mechanism, including: two scissors arm groups 36, each scissors arm group being formed by cross-hinging an even number of support arms, so that the scissors arm group has two lower ends and two upper ends; one of the two lower ends of the scissors arm group is hinged to the base; the upper ends of the scissors arm groups on the same side are hinged to the tabletop, and the other lower end of the two lower ends of the scissors arm group is hinged in the horizontal slide rail 365 on the base; the upper ends of the scissors arm groups on the same side are hinged in the horizontal slide rail on the lower surface of the tabletop. In this way, when any support arm in each scissors arm group is stressed (an upward force), it will rise. Inside the inner sides of the two support arms of the two scissors arm groups 36 near the base, there are pressure plates 372 provided;

[0087] On the base, there are two levers 373 arranged in parallel corresponding to the pressure plates; the front end of each lever presses against the lower surface of the pressure plate 372; at the fulcrum position of each lever on the base, there is a support seat provided, and the fulcrum of the lever is hinged to the support shaft of the support seat;

[0088] On the base, there are springs 3731 provided corresponding to each lever. Under the action of the springs, the driving ends of the two levers can deflect towards each other; the distance between the first positions of the driving ends of the two levers is the first distance. In the figure, the spring 3731 is a tension spring, which is arranged inside near the fulcrum of the driving end of the lever to provide an inward pulling force; it can also be achieved by setting a compression spring outside the lever as needed, and more can be set at the passive end of the lever, etc.

[0089] A manual pressing rod 374 is arranged above the driving ends of the two levers. The manual pressing rod includes a connecting rod, and two inverted V-shaped pressing frames are arranged at both ends of the connecting rod; the two inverted V-shaped pressing frames are arranged corresponding to the driving ends of the two levers; a handle is arranged in the middle of the connecting rod; when the handle is pressed down, the two inverted V-shaped pressing frames move downward, and under the action of the inclined surfaces of the inverted V-shaped pressing frames, the driving ends of the two levers are first pushed to both sides to the second distance; then, it continues to drive the levers downward to complete the rising of the two scissors arm groups;

[0090] An electric pressing rod 375 is arranged at the first position of the driving ends of the two levers; the length of the electric pressing rod is greater than the first distance and less than the second distance; at the upper parts of both ends of the electric pressing rod, there are inclined surfaces corresponding to the two levers; when the electric pressing rod rises, the inclined surfaces push the two levers apart and continue to rise above the two levers; when the electric pressing rod descends, the lower parts of both ends of the electric pressing rod drive the two levers downward to complete the rising of the two scissors arm groups;

[0091] An electric driving device 3751 drives the electric pressing rod to rise or fall;

[0092] When the manual pressing rod is manually pressed, the two inverted V-shaped pressing frames squeeze the levers to both sides to make them "split open", as shown in Figure 1At point A in the middle; at this time, the lever and the electric pressure rod cannot contact each other and form a separated state. The lever can only be driven by the "manual pressure rod", thereby achieving manual priority.

[0093] Example 1 is complete

[0094] To grill both sides of the food, a flipping device is required. This can be an electric flipping device, such as one that uses a motor to rotate the skewers 180 degrees. Alternatively, a manual flipping device can be used, where the skewers are manually flipped 180 degrees. Alternatively, a passive flipping device can be used, where the skewers are passively flipped 180 degrees during the rise or fall of the grilling rack, which can reduce costs.

[0095] Example 2

[0096] Figure 6 and Figure 7 The diagram shows an embodiment of an electric flipping device. Four skewers 223 are mounted on a skewer rack 22. Four rotating shafts 221 are provided on the skewer rack corresponding to the skewers. As shown in the figure, the rotating shafts are rotatably mounted on the skewer rack, with one portion located outside the rack and another portion located inside. The rotating shafts and skewers are detachably coupled. For example, the ends of the skewers are flat and pointed, and a flat receptacle that fits the skewers is provided on at least one of the rotating shafts located inside the rack (or the entire rotating shaft). When the skewers are inserted into the receptacles, they form a rotating shaft together with the rotating shaft. A magnetic recess may also be provided on the rotating shaft that fits the front ends of the skewers. When the skewers are inserted into the magnetic recesses, they form a rotating shaft together with the skewers due to magnetism.

[0097] A sprocket 224 is coaxially mounted on each rotating shaft outside the skewer rack. Two adjacent sprockets are connected by a chain ring, thereby connecting all the skewers together for interlocking movement. A drive motor 222 is mounted on one side of the skewer rack, and an output shaft 225 of the drive motor is mounted on the output shaft 225. The sprocket is connected to the sprocket on the rightmost rotating shaft through a chain ring. In this way, the drive motor can achieve a 180-degree flip (face-up) of all the skewers simultaneously.

[0098] Example 3 (Y-shaped guide rail flipped over)

[0099] This embodiment is an improvement of the embodiment 2. The improvement lies in that the connection between the rotating shaft and the output shaft of the driving motor in the embodiment 2 is changed to that between the rotating shaft and the passive flipping mechanism.

[0100] like Figures 8 to 11 As shown, in this embodiment, the passive flipping mechanism uses an inverted Y-shaped flipping guide rail for flipping, including:

[0101] An inverted L-shaped slider 381, the inverted L-shaped slider includes a support arm 3811 and a cylindrical slider head 3812 arranged at the front end of the support arm; a one-way transmission mechanism 382 is arranged between the lower end of the support arm and the drive shaft 384; the one-way transmission mechanism 382 is composed of a ratchet barrel 3821 and a ratchet pawl 3822 coaxially arranged with the drive shaft 384. The other end of the drive shaft is connected to any rotating shaft on the skewer grill, and the inverted L-shaped slider is driven during the rise or fall of the rotating shaft (the lifting rod of the one-way transmission mechanism 382 in the figure is only for illustrative purposes of understanding).

[0102] A flipping guide rail 383 is arranged vertically corresponding to the inverted L-shaped slider, and a flipping chute adapted to the cylindrical slider head is arranged on the flipping guide rail; the flipping chute includes an upper vertical chute 3831, an inverted Y-shaped flipping chute 3832 and a lower vertical chute 3833 from top to bottom, and the inverted Y-shaped flipping chute includes an upper inclined chute, a horizontal chute and a lower inclined chute communicated with each other; the upper end of the upper inclined chute is communicated with the lower end of the upper vertical chute; the lower end of the lower inclined chute is communicated with the lower vertical chute;

[0103] The cylindrical slider head is slidably arranged in the chute; the flipping process of the inverted L-shaped slider in the flipping chute includes:

[0104] 1) Moving straight up; when the lifting device drives the drive shaft to move upward from bottom to top, the inverted L-shaped slider moves upward along the lower vertical chute driven by the drive shaft. At this time, the inverted L-shaped slider is directly above the drive shaft;

[0105] 2) Flipping the first 45 degrees; when the inverted L-shaped slider moves up to the lower inclined chute, the inverted L-shaped slider moves up along the lower inclined chute and flips 45 degrees;

[0106] 3) Flipping the second 45 degrees; after the inverted L-shaped slider moves up along the lower inclined chute and flips 45 degrees, it continues to slide into the horizontal chute for the second 45-degree flip; at this time, the inverted L-shaped slider is located in the horizontal chute; the hinged end of the drive shaft is located at the intersection of the Y-shaped flipping chute;

[0107] 4) Flipping the third 45 degrees; during the process of the inverted L-shaped slider continuing to move up, the hinged end of the drive shaft drives the inverted L-shaped slider to slide into the upper inclined chute and flips the third 45 degrees; at this time, the inverted L-shaped slider is behind the drive shaft;

[0108] 5) Flipping the fourth 45 degrees; during the process of continuing to move up, the hinged end of the drive shaft drives the inverted L-shaped slider to slide out of the upper inclined chute and into the upper vertical chute to complete the fourth 45-degree flip;

[0109] During the downward movement, the restoration can be completed by running in the reverse direction from step 5;

[0110] During the above flipping process, since a one-way transmission mechanism is provided between the inverted L-shaped slider and the drive shaft; therefore, during the upward (or downward) movement, the inverted L-shaped slider will drive the drive shaft to flip simultaneously, while during the downward (or upward) movement, the inverted L-shaped slider will not drive the drive shaft to flip simultaneously under the action of the one-way transmission mechanism.

[0111] This turning device realizes turning during the rising and falling processes of the lifting device, has a simple structure and is convenient to use, without the need to adopt a separate electric turning device.

[0112] Furthermore, as a further improvement of this embodiment, a positioning device can be provided corresponding to the drive shaft to prevent the food skewer from flipping itself due to imbalance on both sides of the food skewer. The structure of the positioning device is relatively simple and can be designed according to needs. For example, a pit is provided on the drive shaft, and a spring bead is correspondingly provided at the position corresponding to the pit, and a certain positioning effect is realized by using the spring bead and the pit.

[0113] Embodiment 4 (Double-track turning)

[0114] This embodiment is an improvement of Embodiment 2. The improvement lies in: changing the connection between the rotating shaft and the output shaft of the drive motor in Embodiment 2 to the connection between the rotating shaft and the passive turning mechanism.

[0115] As Figure 12 and Figure 13 shown, in this embodiment, the passive turning mechanism adopts a double-track gear turning device. As shown in the figure, it includes a lifting slide rail 391, and the lifting slide rail can be arranged on one side corresponding to the base or the heating device; a slider 392 is arranged on the lifting slide rail 391, and the slider 392 slides up and down along the lifting slide rail under the action of an external force (the rotating shaft on the skewer rack);

[0116] The turning device includes:

[0117] Both ends of the lifting slide rail are provided with track clamping heads 393;

[0118] A turning track 394 is arranged in parallel on one side of the lifting slide rail; the turning track is provided with a toothless section and a rack section 3941;

[0119] A drive shaft bracket 395 is arranged on the slider. A drive shaft 396 is horizontally arranged in the front section of the drive shaft bracket. A grill mechanism is installed at the front end of the drive shaft, and a spline tooth is arranged at the tail of the drive shaft; a gear 398 that can mesh with the rack of the rack section is arranged at the tail of the drive shaft bracket; the gear shaft extends into the rear section of the drive shaft bracket and is coaxially arranged with the drive shaft; a spline hole is arranged at one end of the gear shaft extending into the drive shaft bracket, and the spline hole of the gear shaft is sleeved on the spline tooth of the drive shaft for transmission connection; in this way, when the gear is pushed outwards, the gear shaft and the drive shaft still maintain a transmission relationship through spline connection.

[0120] The length of the described rack segment is equal to 1 / 2 of the gear circumference; in this way, when the gear passes through the gear segment, it just flips 180 degrees.

[0121] A shifting shaft mechanism 397 capable of shifting the shaft of gear 398 axially is provided on the described drive shaft bracket; the shifting shaft mechanism includes at least one shifting rod, and the shifting rod is arranged corresponding to the switching rail chuck.

[0122] When the slider is controlled to rise, the gear correspondingly runs upward along the flipping track. When it is in the toothless segment, the drive shaft does not act.

[0123] When the gear runs to the rack segment driven by the slider, the gear rotates 180 degrees under the action of the rack segment and then continues to rise.

[0124] After continuing to rise under the action of the slider and making the shifting rod touch the upper switching rail chuck, the shifting shaft mechanism shifts the gear to one side of the flipping track.

[0125] The slider is controlled to descend; after continuing to descend under the action of the slider and making the shifting rod touch the lower switching rail chuck, the shifting shaft mechanism shifts the gear onto the flipping track.

[0126] Furthermore, as a further improvement of this embodiment, a positioning device can be provided corresponding to the drive shaft to prevent the food skewer from flipping itself due to the imbalance on both sides of the food skewer. The structure of the positioning device is relatively simple and can be designed according to needs. For example, a pit is provided on the drive shaft, and a spring bead is correspondingly provided at the position corresponding to the pit, and a certain positioning effect is achieved by using the spring bead and the pit.

[0127] Embodiment 5 (Gear turning over)

[0128] This embodiment is an improvement of Embodiment 2. The improvement lies in: changing the connection between the rotating shaft and the output shaft of the drive motor in Embodiment 2 to the connection between the rotating shaft and the passive turning-over mechanism.

[0129] As Figure 14 and Figure 15 shown, this embodiment is an embodiment of another turning-over device.

[0130] The guide rail 373 can be arranged on the corresponding side of the base or the heating device; the guide rail includes an upper vertical supporting rail 3731, a lower vertical supporting rail 3733 and a tooth rail 3732 formed by a plurality of equally spaced tooth columns in the middle; among them, the trajectories of the upper vertical supporting rail and the lower vertical supporting rail are on the same vertical line, and the trajectory of the tooth rail is arranged in parallel and spaced from the trajectories of the upper vertical sliding rail and the lower vertical sliding rail.

[0131] Slider: A gear 3741 meshing with the tooth columns of the tooth rail; Smooth sections 3742 adapted to the upper vertical resting rail and the lower vertical resting rail are integrally provided at opposite ends of the gear; Thus, a slider is formed with oppositely arranged smooth sections, oppositely arranged gear sections, and an integral structure.

[0132] A wedge-shaped section 3743 is formed between the smooth section and the gear section, and a guide groove is provided at the junction of the wedge-shaped section and the smooth section; A one-way passing mechanism 3745 is provided at the guide groove; On the slider of the two one-way passing mechanisms, a chute 3744 parallel to the smooth section is provided; The chute is adapted to the tooth columns of the tooth rail.

[0133] As Figure 14 shown, one end of the drive shaft is coaxially arranged on the gear, and the other end of the drive shaft is connected to any rotating shaft on the skewer rack. When the skewer rack drives the rotating shaft to rise, it simultaneously drives the drive shaft to rise; The drive shaft then drives the slider to rise, and the smooth section of the slider slides upward against the lower vertical resting rail; The other end of the drive shaft is connected to any rotating shaft on the skewer rack.

[0134] When the slider slides upward to the tooth rail under the action of the rotating shaft on the skewer rack, due to the existence of the one-way passing mechanism, under the action of the wedge-shaped section, the gear section meshes with the tooth rail, and the slider continues to move upward along the tooth rail and flips 180 degrees. Subsequently, the gear section disengages from the tooth rail, and the other smooth section of the slider slides upward against the upper vertical resting rail.

[0135] As Figure 15 shown, when the drive shaft drives the slider to descend, the smooth section of the slider slides downward against the upper vertical resting rail.

[0136] When the slider slides downward to the tooth rail, due to the fact that the one-way passing mechanism is in the passing state in this direction, the chute of the slider is in the open state, and the chute descends through the tooth rail downward; And after passing through the tooth rail, it continues to move downward by relying on the smooth section against the lower vertical resting rail.

[0137] Furthermore, as a further improvement of this embodiment, a positioning device can be provided corresponding to the drive shaft to prevent the skewer from flipping itself due to the imbalance on both sides of the food skewer. The structure of the positioning device is relatively simple and can be designed according to needs. For example, a concave pit is provided on the drive shaft, and a spring bead is correspondingly provided at the position corresponding to the concave pit, and a certain positioning effect is achieved by using the spring bead and the concave pit.

[0138] Embodiment 6 (Flip with a push rod)

[0139] This embodiment is an improvement of Embodiment 2.

[0140] As Figures 16 to 21 shown, the flipping device includes: A rotation driving structure and a positioning structure are provided on the rotating shaft 221.

[0141] Among them, the rotation driving structure includes: a push rod 11 is provided on the same side of each rotation axis. The push rod can be vertically upward on the upper surface of the base or vertically downward on the lower surface of the heating device. Its function is to push the contact rod 2211 when they are in contact, so as to push it to rotate, thereby driving the rotation axis to rotate;

[0142] A contact rod 2211 is radially arranged on the rotation axis at the position corresponding to the push rod. Both ends of the contact rod are outside the rotation axis, and the two lengths of the contact rod outside the rotation axis are equal;

[0143] The positioning structure includes: a positioning plate 2212 is radially arranged on the rotation axis. Both ends of the positioning plate are outside the rotation axis, and the two lengths of the positioning plate outside the rotation axis are equal; the contact rod and the positioning plate are arranged at intervals; a positioning spring piece 226 that abuts against the positioning plate is arranged on one side of the positioning plate. As shown in the figure, the length of the positioning spring piece should be longer than that of the positioning plate; when the lifting device rises ( Figure 21 and Figure 22 shown) or descends ( Figure 17 and Figure 18 shown) away from the push rod, the positioning spring piece 226 presses against one side plate surface of the positioning plate 2212, so that the end of the contact rod on the rotation axis near the push rod is arranged at an acute angle with the push rod;

[0144] As Figure 19 shown, when the lifting device descends or rises to the point where one end of the contact rod is pressed by the push rod, the contact rod drives the rotation axis to start rotating, and rotates more than 90 degrees during the subsequent descent process. The above angle is the minimum angle. When the contact rod is thinner, after its rotation angle exceeds 90 degrees, the positioning of the rotation axis can be completed with the help of the positioning spring piece; when the contact rod is thicker and forms a rectangular block, its end face is thicker, and its rotation angle usually has to exceed 135 degrees to complete the positioning of the rotation axis with the help of the positioning spring piece.

[0145] □ After adding the above lifting and turning functions, it has the following advantages:

[0146] 1) Bake one side until it is thoroughly baked and charred, and then turn over the baking head to bake the other side until it is charred. This barbecue mode can better exert the effect of the "Maillard reaction" and has a better taste;

[0147] 2) The heating device is "placed on top", which can prevent grease from dripping onto the barbecue head, reducing oil fume or preventing fire;

[0148] 3) In the past, a certain distance had to be maintained. If it was too close, oil splashing could cause a fire or it was easy to get scorched. However, maintaining a certain distance often led to a very long grilling time. Therefore, we moved the food closer to the grilling head, lowered and flipped it after grilling for a certain time. This not only saved time, eliminated safety problems, but also enhanced the grilling effect, achieving three benefits with one action.

[0149] 4) North American power outlets generally can only withstand a heating power of no more than 2 kilowatts, which results in a long time and poor effect for large-volume ovens or air fryers. After adopting the lifting and flipping functions, it can be greatly improved.

[0152] As described above, the above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model.
