Description

Technical Field

[0001] The present application relates to a portable barbecue device and a driving mechanism and a barbecue skewer positioning mechanism thereof. Background Art

[0002] Barbecue is not only a cooking method, but also refers to the food processed by this cooking method. The industry has developed a variety of barbecue equipment that is easy to move to meet market needs.

[0003] A Chinese utility model patent, granted with the authorization number CN205018877U, discloses a touch-controlled barbecue grill. The grill includes a base, a grill lock plate for supporting grill skewers, and multiple door panels positioned between the base and the grill lock plate, each corresponding to the grill skewers. The door panels are pivotally connected between the base and the grill lock plate. A touchscreen is provided on the outer wall of the base for adjusting the grill temperature and the speed of the grill skewers through touch control. The base includes a controller electrically connected to the touchscreen, a timer electrically connected to the controller, and a speed sensor for sensing the speed of the grill skewers. The door panels of this utility model correspond to the grill skewers one by one and are pivotally connected between the base and the grill lock plate. This provides excellent dustproofing, convenient access to the grill skewers, and high precision in temperature and speed control.

[0004] Chinese invention patent publication number CN101125064B discloses a vertical and horizontal oven, specifically a grilling oven that can be used in both horizontal and vertical orientations. Depending on the specific orientation, the oven can be used to bake, roast, grill, and roast foods such as meat, fish, and vegetables. It is intended to allow for all or only some of the aforementioned functions to be performed in both horizontal and vertical orientations.

[0005] Analyzing the above two prior arts and all other prior arts, it can be seen that the existing barbecue equipment has at least the following disadvantages during the barbecue process:

[0006] 1. The ingredients (skewers) and the heating source are both stationary, which will obviously lead to uneven heating of the ingredients and affect the quality of the barbecue. It has gradually withdrawn from the market.

[0007] 2. The rotation of each ingredient is called "rotation". The different distances and angles between the heating source and each skewer will cause different skewers to be heated unevenly. This will obviously affect the cooking quality, uniformity and user experience of the skewers.

[0008] 3. The overall rotation of the ingredients is called "revolution". The relative distance and angle between the skewers and the heating source remain fixed, but each skewer has the opportunity to receive the corresponding heat at the same distance and angle. Obviously, this will also cause different skewers to be heated unevenly, affecting the cooking quality, uniformity and user experience of the skewers.

[0009] 4. The functional integration of components is not high. For example, the cooking time of each skewer cannot be independently controlled and integrated with the clamping mechanism, resulting in problems such as complex overall structure. Summary of the Invention

[0010] The purpose of the present application is to provide a portable barbecue device, a driving mechanism for the barbecue device, and a skewer positioning mechanism for the barbecue device, so as to solve at least one of the above problems.

[0011] In order to achieve one of the above objectives, this application provides the following technical solutions:

[0012] A portable barbecue device comprises: a skewer positioning mechanism for limiting the food portion of the skewers to the outside of the circumference of a heating source; a revolution drive mechanism connected to the skewer positioning mechanism for driving the skewer positioning mechanism to rotate around the heating source; and a rotation drive mechanism connected to the skewer positioning mechanism for driving the skewer positioning mechanism to rotate around itself.

[0013] Analysis shows that the present application can drive the skewers to rotate around the heating source, and each skewer can also rotate around itself. In this way, each skewer can receive heat from any position in the circumferential direction of the heating source, and each position of each skewer can "face" the heating source, so that the skewers can be cooked faster and more evenly, thereby bringing a better taste and appearance.

[0038] The present application will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0039] It should be noted in advance that although this application includes electrical devices such as motors, controllers, sensors, communication cables (for transmitting low-voltage detection and control signals, etc.) / power cables (for transmitting electricity for heating sources, etc.), this application does not specifically explain or describe in detail the structure and materials of these electrical components themselves, because this application does not contribute to the technology of electronic circuits, electrical components, etc., but only utilizes its relevant characteristics. After knowing the existing technology in this field and reading the instructions of this application, the control process is clear, so the corresponding control, communication, current transmission and other details will not be repeated.

[0040] like Figure 1 、 Figure 3 、 Figure 8 、 Figure 9 As shown, from the overall appearance, the portable barbecue device embodiment 1 provided by the present application includes a base 1100, an oil receiving tray 2100, a support frame 3100, a top cover 4100, a skewer positioning mechanism 5100, and a door leaf 6100. Among them, the base 1100 is disc-shaped, mainly to provide stable support for the various components above. The lower end of the support frame 3100 is connected to the base 1100, and the upper end is connected to the top cover 4100 and the components inside it. If the lower end of the support frame 3100 can provide stable support, the base 1100 can also be omitted, for example, by inserting the lower end of the support frame 3100 into a groove, or by forming a "door"-shaped frame with two or more support frames 3100. In this embodiment 1, the support frame 3100 is a vertical tube, the hollow structure of which can provide routing space for power and communication cables. The appearance is simple and the cables can be protected.

[0041] The oil pan 2100 has a groove on its upper surface, located substantially below the base 1100 and below the door 6100. Since the interior of the door 6100 is the grilling space, the groove on the upper surface of the oil pan 2100 is preferably slightly larger than the opening below the door 6100 to catch any falling grease and impurities. The oil pan 2100 and the base 1100 can be fixedly connected or removably connected. A removable connection, such as a snap-on connection, magnetic attraction, or fastener connection, facilitates removal and cleaning of the oil pan.

[0042] The door leaf 6100 is in the shape of an arc-shaped plate. This embodiment includes two door leaves 6100, and the rear end edges of the two door leaves can be rotatably set on the support frame 3100 through a hinge 6103. At the same time, a position sensor 6104 is also provided on the rear end edge for detecting the open / closed state of the door leaf 6100, thereby providing a signal to the driving mechanism described below. After the two door leaves 6100 are enclosed, a cylindrical internal space is formed, and the internal space is the barbecue space mentioned above. In order to facilitate the opening / closing of the door leaves 6100, at least one door handle 6101 is provided on the side of each door leaf 6100. The door handle 6101 is preferably arranged horizontally, which can be used not only to open the door leaf 6100, but also to move this embodiment with both hands.

[0043] Top cover 4100 is located substantially at the top of the first embodiment, covering and protecting the internal motor, transmission mechanism, and control components. It resembles a downward-facing bowl-shaped structure. An open space exists between top cover 4100 and door leaf 6100. A portion of skewer positioning mechanism 5100 is located within this open space. This saves material, facilitates user placement of skewers, enhances aesthetics, and, if a signal indicating the cooking time is also located on skewer positioning mechanism 5100, allows the user to easily observe the signal through this open space.

[0044] For example Figure 3 、 Figure 4 、 Figure 9 As described, inside the top cover 4100, there are provided a power output mechanism, a supporting connection, a revolution drive mechanism, a rotation drive mechanism, etc. It should be emphasized that the power output mechanism not only includes a motor 7101, a reduction gear 7102, and an output gear 7103, but also includes a controller for controlling the operation of the motor 7101. The controller is not shown in the figure (because the technology for controlling the motor by the controller is conventional technology), and the controller is connected to the aforementioned position sensor 6104. According to the position information of the door leaf 6100 collected by the position sensor 6104, the controller controls whether the motor 7101 moves and the stop position, thereby stopping the skewer positioning mechanism 5100 at a preset position.

[0045] The supporting connecting members include crossbeam 4101, connecting rod 4103, connecting rod 4104, connecting rod 4105, connecting rod 4106, and pad 4107. In other embodiments, any supporting and connecting member can provide stable support for the power output mechanism, revolution drive mechanism, and rotation drive mechanism. The number, structure, and positional relationship of the supporting and connecting members can be flexibly changed. For example, pad 4107 is fixed to crossbeam 4101 via connecting rod 4104. Obviously, welding or bonding can also achieve similar purposes.

[0046] Crossbeam 4101 is a rod-shaped structure, one end of which is fixed to the top of support frame 3100. The other end is preferably bent downward in an L-shape and abuts / connects to the upper surface of protective ring 4102, which is described in detail below. Protective ring 4102 is annular, with a large hollow area in the center for passing the drive mechanism, etc., and is fixed to support frame 3100, crossbeam 4101, etc. The outer edge is close to the inner wall of top cover 4100 to prevent oil smoke, impurities, etc. from entering the top cover 4100 and causing contamination.

[0047] Pad 4107 is approximately pancake-shaped and secured to the middle section of beam 4101 via a connecting rod 4104 formed by, for example, two bolts. The upper end of another connecting rod 4106 passes through pad 4107 and is secured to beam 4101. The lower end of connecting rod 4106 extends straight down into the baking space enclosed by door leaf 6100, where it connects to a protective cover 8102. This rod also supports the weight of the heating tubes used as heat source 8100, as detailed below.

[0048] As mentioned above, the power output mechanism includes a motor 7101, a reduction gear 7102, an output gear 7103, a controller, etc., which are arranged on the crossbeam 4101. The motor 7101, the reduction gear 7102, and the output gear 7103 are connected in sequence. The connection method and the control of the motor by the controller are conventional technologies and will not be repeated here.

[0049] The revolution drive mechanism is used to drive the skewer positioning mechanism 5100 to rotate around the heat source 8100, while the rotation drive mechanism is used to drive the skewer positioning mechanism 5100 to rotate. The revolution drive mechanism includes a rotating toothed disc 7104. The rotating toothed disc 7104 is disc-shaped, with gear teeth on its outer edge that mesh with the output gear 7103. The inner edge of the outer edge is connected to multiple skewer positioning mechanisms 5100 via a connecting rod 4103. Multiple skewer positioning mechanisms 5100 are distributed in a ring shape below the rotating toothed disc 7104 around the center of the circle. The central area of ​​the rotating toothed disc 7104 is movably disposed below the pad 4107, so that when the output gear 7103 drives the rotating toothed disc 7104 to rotate, the rotating toothed disc 7104 can also rotate, thereby driving the multiple skewer positioning mechanisms 5100 mounted thereon to rotate, creating a "revolution" effect, thereby allowing the skewers 9 to pass through every position on the circumference of the heat source 8100.

[0050] The self-rotating drive mechanism includes a passive gear 7105 and a stationary toothed disc 7106. The stationary toothed disc 7106 is stationary during use and is located below the rotating toothed disc 7104. Ball bearings or the like may be provided between the two to provide a spacing, thereby reducing friction and limiting their relative positions. A connecting rod 4105, similar to a bolt, has its large end at the bottom, with its threaded end passing through the stationary toothed disc 7106 and the rotatable rotating toothed disc 7104 (it should be understood that "passing through the rotating toothed disc" here refers to their relative spatial positions, not a fixed connection between the two), and then screwed into the spacer 4107, which has multiple functions, such as supporting the stationary toothed disc 7106 and the rotating toothed disc 7104. The driven gear 7105 is fixedly connected to the connecting rod 4103, and the two can rotate simultaneously. The connecting rod 4103 also has a larger upper end, which is located above the rotating toothed disc 7104. The rotating toothed disc 7104 is provided with a through hole. The connecting rod 4103 passes through the through hole and then passes through the driven gear 7105, and is also fixedly connected to the driven gear 7105. The lower end of the connecting rod 4103 is fixedly connected to the skewer positioning mechanism 5100. When the driven gear 7105 rotates, the skewer positioning mechanism 5100 also rotates, forming a "rotational" effect, that is, the skewer 9 itself rotates.

[0051] like Figure 3 、 Figure 5 、 Figure 7 、 Figure 9As shown, the skewer positioning mechanism 5100 not only provides stable gripping for the skewers 9 but is also an essential component for their rotation. Preferably, the skewer positioning mechanism 5100 comprises a longitudinally arranged base plate 5105, a connecting plate 5102, a clamping plate 5103, a clamping plate 5106, and a clamping plate 5107. The connecting plate 5102 is located on the upper portion of the base plate 5105 and is connected to the connecting rod 4103. The clamping plates 5103, 5106, and 5107 are arranged one above the other on the same side of the base plate 5105, from top to bottom, to clamp the skewers 91 of the skewers 9 and prevent them from moving. Of course, there are many ways to prevent the movement of a single rod-shaped structure, including varying the number, structure, and location of the clamping plates. For example, a notch in an elastic plate can securely lock the skewers. Alternatively, a hook formed on the base plate 5105 can be used to suspend the skewers 91 and stabilize their position.

[0052] In one embodiment of the present invention, each of the clamping plates 5103, 5106, and 5107 is provided with a receiving notch 5104. Preferably, the receiving notch 5104 is arc-shaped. The three receiving notches 5104 correspond to each other up and down, and are used to clamp the skewer 91 therein to prevent it from falling. Generally speaking, the skewer 91 has a certain elasticity, and the three receiving notches 5104 are slightly misaligned in the horizontal direction, so that the clamping effect of the skewer 91 is better. The clamping plates 5103, 5106, and 5107 also have an effect: to achieve "three-point positioning". The three receiving notches 5104 support the skewer 91 at three different heights, so that the longitudinal positioning effect of the skewer 91 is better. In order to better position the skewer 91 and prevent it from sliding downward, a clamping plate 5109 is further provided on the clamping plate 5107. The clamping plate 5109 is elastic, with one end fixed to the clamping plate 5107 and the other end 5109 extending toward the receiving notch 5104. More preferably, the edge of the other end 51010 of the clamping plate 5109 is finer and thinner, which can form a blade-like effect, thereby having a better clamping effect on the skewer 91, especially when the skewer 91 is made of bamboo or wood.

[0053] For example Figure 7 As shown, the skewer positioning mechanism 5100 of the first embodiment is also integrated with a time prompt mechanism for detecting when the skewer 9 is inserted into the storage notch 5104, timing the baking time, and reminding when the baking is completed. Preferably, the time prompt mechanism includes a position sensor 5101, a power supply, a time controller, and a light-emitting diode 5108 connected by cables. The power supply and time controller are not shown in the figure and are arranged on the back of the substrate 5105, i.e. Figure 7The power source can be a small battery, such as a button battery. The position sensor 5101 can be a small sensor such as a micro switch or Hall effect sensor. Such sensors are used to detect the proximity or contact of an object, such as detecting the insertion of the skewer 91 into the storage notch 5104. This is a common application and will not be described in detail here. When the skewer 91 is inserted into the storage notch 5104, the position sensor 5101 is triggered to send a timing start signal to the time controller. The time controller controls the power supply to the LED 5108, causing the LED 5108 to illuminate. During the baking process, the time controller counts the time and controls the LED 5108 to emit a prompt signal after the baking time is completed. For example, the LED 5108 can be turned off or flashing to indicate a prompt. Preferably, in this embodiment, there are two LEDs 5108, and the control logic can be such that one illuminates during the baking process and both illuminate when the baking is complete, or vice versa. Alternatively, one of the two LEDs 5108 can be green and the other red, with the green light being on during the baking process and the red light being on when the baking is complete. It should be understood that the light emitting diode 5108 used as a prompt may also be other types, such as a buzzer, etc. After the predetermined time is reached, the buzzer emits a sound which also falls within the scope of protection of this application.

[0054] Again Figure 3 、 Figure 5 、 Figure 6 、 Figure 9 As shown, connecting rod 4106 extends from top to bottom to a height equivalent to the lower middle portion of door leaf 6100. A partition plate 8101 is positioned in the middle of connecting rod 4106. A protective cover 8102 is positioned between partition plate 8101 and the lower end of connecting rod 4106. Protective cover 8102 is shaped like a cup, with a cylindrical side surface and a flat bottom. Preferably, the upper edge of protective cover 8102 abuts the lower surface of partition plate 8101, and its bottom surface is connected to the lower end of connecting rod 4106.

[0055] Protective cover 8102 is provided outside of heating source 8100 to prevent grease and other substances from splattering from skewers 9 from contaminating heating source 8100. Preferably, protective cover 8102 is made of a material with good thermal conductivity. To facilitate heat conduction, through holes 8104 are provided on the bottom surface of protective cover 8102. Through holes 8104 not only facilitate heat conduction but also guide hot air downward and then upward, thereby forming a bottom-up hot air flow, allowing the skewers to receive heat more comprehensively.

[0056] Furthermore, the lower middle portion of the connecting rod 4106, which overlaps in height with the heating source 8100, is covered with a heat insulating layer 8103 to prevent excessive heat from being conducted upward through the connecting rod 4106, causing heat waste and affecting the devices at the upper end.

[0057] The heating source 8100 is composed of two U-shaped heating tubes. Heating tubes that use electricity to generate heat are already well known in the field of kebab technology and will not be described in detail. Of course, in this embodiment, there is no limitation on the number and arrangement of the heating tubes in the pair of heating sources 8100, and the use of two U-shaped heating tubes is not limited.

[0058] During the heating process of the skewers 9, the grease and water therein will splash inward to the outer surface of the protective cover 8102 and outward to the inner surface of the door leaf 6100. The grease splashed to the outer surface of the protective cover 8102 and the inner surface of the door leaf 6100 will fall into the oil receiving pan 2100. However, when the door leaf 6100 is opened and the skewers 9 are taken out, the grease, water, etc. splashed to the inner surface of the door leaf 6100 will continue to flow down and fall to the area outside the oil receiving pan 2100, causing pollution and bringing unnecessary cleaning work. To avoid this problem, the present embodiment 1 is provided with a guide plate 6102 inside the door leaf 6100. The guide plate 6102 is slender, and one side is provided on the inner surface of the door leaf 6100. Preferably, one end of the deflector 6102, which is closer to the outer side of the door leaf 6100, is higher than the other end closer to the inner side of the door leaf 6100 (closer to the support frame 3100), so as to facilitate the flow of grease and water that have fallen onto the deflector 6102. Specifically, when the door leaf 6100 is closed, the deflector 6102 and the door leaf 6100 are both located above the oil receiving pan 2100, and grease, water, etc. will naturally fall into the oil receiving pan 2100. When the door leaf 2100 needs to be opened to take or put the skewers 9, the door leaf 6100 rotates around the hinge 6103, and one end of the deflector 6102 leaves the oil receiving pan 2100, but the other end, which is lower in height, will "rotate" into the oil receiving pan 2100, and the deflector 6102 guides the grease and water to continue flowing into the oil receiving pan 2100.

[0059] When using this first embodiment, the power supply is turned on to supply power to the heating source 8100, motor 7101, position sensor 6104, controller, etc.; the door 6100 is opened, and a skewer 91 of a skewer 9 is inserted into the receiving notch 5104 of the skewer positioning mechanism 5100. The skewer 91 triggers the position sensor 5101, and the green light-emitting diode 5108 is illuminated. Of course, the above two steps can be interchanged.

[0060] During the grilling process, the revolution drive mechanism rotates all skewers 9 around the protective cover 8102 outside the heat source 8100, while the rotation drive mechanism rotates the skewer positioning mechanism of each skewer 9. The heat source 8100 radiates heat in all directions, causing grease and moisture from the skewers 9 to splatter, falling along the protective cover 8102 and the inner surface of the door leaf 6100 / deflector 6102 into the oil pan 2100.

[0061] When the predetermined baking time is reached, for example, five minutes, the red LED 5108 lights up. The user sees the prompt and holds the door handle 6101 to open the door leaf 6100. The position sensor 6104 detects that the door leaf 6100 is open and sends the signal to the controller. The controller controls the motor 7101 and the transmission mechanism to operate to the outward position of the skewer positioning mechanism 5100, which is a position convenient for taking and placing the skewers 9.

[0062] Remove the mature skewers 9, and the light emitting diode 5108 goes out. Put the fresh skewers on, the position sensor 5101 detects the new skewers, starts timing, and the green light emitting diode 5108 lights up.

[0063] When the door leaf 6100 is closed, the position sensor 6104 detects that the door leaf is closed and sends the trigger signal to the controller. The controller controls the motor 7101 and the transmission mechanism to operate and continue to drive the revolution drive mechanism and the rotation drive mechanism to rotate.

[0064] Repeat this process.

[0065] like Figures 10-17 As shown, especially Figure 10-11 、 Figure 16-17 As shown, from the overall appearance, the second embodiment of the portable barbecue device provided by the present application includes a base 1200, an oil receiving tray 2200, a support frame 3200, a top cover 4200, a skewer positioning mechanism 5200, and a door leaf 6200. Among them, the relative positions and functions of the base 1200, the oil receiving tray 2200, the support frame 3200, the top cover 4200, and the door leaf 6200 are basically the same as those in the first embodiment, and will not be elaborated on in detail. Similarly, the hinge 6203 between the door leaf 6200 and the support frame 3200, the door handle 6201, and the guide plate 6202 on the inner wall of the door leaf 6200 also have the same functions and positional relationships as those in the first embodiment, and will not be elaborated on in detail. As for the skewers 9 and skewers 91, they are marked with the same reference numerals as in the first embodiment, that is, the first and second embodiments can be directed to the same type of skewers.

[0066] However, it should be emphasized that Example 2 also includes electrical devices such as controllers, sensors, communication cables / power cables, but the following does not specifically explain or describe in detail the structure and materials of these electrical components. Example 2 does not contribute to electronic circuit electrical components. It only utilizes their relevant characteristics and functions. After knowing the existing technology in this field and reading the description of this application, the control process is clear, so the corresponding control, communication, current transmission and other details are not repeated.

[0067] Similar to the first embodiment, the support frame 3200 is also a vertical tube. Figure 11As shown, the lower end of the support frame 3200 has a circular hole for passing power and communication cables (the circular hole is not shown in the drawings of the first embodiment). The hollow structure of the support frame 3200 can also provide space for routing power and communication cables. On the upper end of the support frame 3200, there is a bent crossbeam 3201. The other end of the crossbeam 3201 extends toward the axis position of the second embodiment and then bends downward to connect with the top cover 4200, thereby forming a space between the crossbeam 3201 and the top cover 4200, which is convenient for the user to insert the finger, so that the crossbeam 3201 functions as a handle.

[0068] As previously mentioned, the top cover 4200 is located near the top of the second embodiment, with its center connected to the bend of the crossbeam 3201. The overall structure still resembles a downward-opening bowl, serving to cover and protect the internal motor, transmission mechanism, and other components. A portion of the skewer positioning mechanism 5200 is exposed within an open space between the top cover 4200 and the door leaf 6200.

[0069] Similarly, the second embodiment also includes a revolution drive mechanism and a rotation drive mechanism capable of driving the barbecue skewers 9 to achieve self-rotation and revolution. The definitions of self-rotation and revolution and their beneficial effects are the same as described above. For example, the top cover 4200 of the second embodiment is provided with a handle 4208 as the revolution drive mechanism. Operating the handle 4208 can drive the top cover 4200 and its internal power output mechanism, rotation drive mechanism, barbecue skewers 9, etc. to rotate around the axis of the connecting rod 7202 (the connecting rod 7202 can be rotated or fixed). In other words, the components "suspended" at the other end of the crossbeam 3201 can basically be configured to be rotatable.

[0070] Preferably, handle 4208 is disposed on the upper surface of top cover 4200 and is in the shape of a short column, exhibiting a simple structure and simplifying manufacture, operation, and maintenance. More preferably, handle 4208 is preferably greater than the distance between crossbeam 3201 and the upper surface of top cover 4200. This prevents handle 4208 from continuously driving the rotation of top cover 4200 and other mechanisms, thereby preventing the cables passing through support frame 3200 and connecting rod 7202, which provide power to the power take-off mechanism and heating source 8200, from becoming tangled or knotted.

[0071] For example Figure 11-13 and Figure 17As shown, inside the top cover 4200, there are provided a power output mechanism, a plurality of supporting connectors, a self-rotating drive mechanism, a skewer positioning mechanism 5200, etc. The supporting connectors provide support and connection for the power output mechanism, the self-rotating drive mechanism, etc. It has the characteristics of many components and diverse functions. The power output mechanism includes a motor 7201, a reduction box 7202, an output pulley 7203, an output pulley shaft 7204, and the self-rotating drive mechanism includes a transmission belt 7205, a tension spring 4207, and a driven wheel 5202 located in each skewer positioning mechanism 5200, etc. All of which require supporting connectors to provide support and connection.

[0072] Specifically, the supporting connectors primarily include a lower support plate 4201, an upper support plate 4202, a lower base plate 4203, a connecting tube plate 4204, an upper ring plate 4205, connecting rods 4206, a connecting plate 4209, a base plate 4210, and a rotating shaft 4211. Arranged parallel from bottom to top, lower base plate 4203, lower support plate 4201, upper support plate 4202, and upper ring plate 4205 are essentially flat plates with rounded outer edges, and connecting rods 4206 extend through the center of each circle. The lower support plate 4201 and the upper support plate 4202 are provided with a plurality of corresponding holes (not marked) on the upper and lower sides. A bearing 5204 and a bearing 5201 of the skewer positioning mechanism 5200 are respectively embedded in the corresponding holes on the lower support plate 4201 and the upper support plate 4202. The lower base plate 4203 is also provided with a hole at the position of the bearing 5204, but it is relatively small, so as to provide support for the bearing 5204 from the bottom. Figure 11 As shown, correspondingly, the upper ring plate 4205 is also provided with a relatively small hole at the position of the bearing 5201, so as to facilitate positioning and supporting the bearing 5201 from above.

[0073] A support block 4212 is provided at the lower end of the connecting rod 4206. The support block 4212 "lifts" the lower base plate 4203 and other components from below to prevent the lower base plate 4203 and other components from falling off the connecting rod 4206. At the same time, a certain distance and space are formed between the adjacent lower base plates 4203, lower support plates 4201, upper support plates 4202, and upper ring plates 4205 by means of sleeves, pads, or other heights. For example, a space is formed between the lower support plate 4201 and the upper support plate 4202 to accommodate the output pulley 7203, the transmission belt 7205, and the driven pulley 5202. Figure 13As shown, a transmission belt 7205 is embedded in the corresponding belt groove 5203 of each output pulley 7203 and driven pulley 5202. When the output pulley 7203, which is arranged on the output shaft of the reduction gearbox 7202, rotates, it drives all the driven pulleys 5202 to rotate. The transmission belt 7205 can be a belt, a synchronous belt, or a chain. The output pulley 7203 is fixed to the output pulley shaft 7204, and the two ends of the output pulley shaft 7204 are respectively arranged on the lower support plate 4201 below and the upper support plate 4202 above.

[0074] In actual operation, after a certain period of operation, the transmission belt 7205 may become loose and the transmission effect may deteriorate. In view of this, the second embodiment provides a tension spring 4207 for tightening the transmission belt 7205. Specifically, Figure 12 、 Figure 13 and Figure 17 As shown, the base plate 4210 is arranged on the upper support plate 4202 through a rotatable rotating shaft rod 4211, the motor 7201 and the reducer 7202 are arranged on the base plate 4210, and a connecting hole (not marked) is provided at the other end of the base plate 4210 relative to the rotating shaft rod 4211, and one end of the tension spring 4207 is inserted into the connecting hole. Another connecting hole is provided on the upper support plate 4202 away from the connecting hole, and the other end of the tension spring 4207 is inserted into the other connecting hole, so that the output pulley 7203 and the output pulley shaft 7204 have a tendency to "move away" from the initial position, thereby tightening the transmission belt 7205.

[0075] Although the aforementioned handle 4208 is provided on the surface of the top cover 4200, in order to enhance the overall structural strength, the second embodiment further comprises a connecting plate 4209, preferably in the shape of a channel steel, with one wing plate connected to the inner wall of the top cover 4200 and the other wing plate connected to the upper ring plate 4205. When the handle 4208 is pushed, the top cover 4200, the lower support plate 4201, the upper support plate 4202, the lower base plate 4203, the upper ring plate 4205, and the like rotate simultaneously.

[0076] like Figure 11 、 Figure 15 and Figure 17As shown, the skewer positioning mechanism 5200 of the second embodiment includes the aforementioned bearing 5201, the aforementioned bearing 5204, a spring 5206, an upper sleeve 5211, a lower sleeve 5208, and a collar 5210. The upper sleeve 5211 is a hollow cylindrical structure, with its upper end extending from the upper ring plate 4205 and secured by a nut. The bearing 5201, the driven wheel 5202, and the bearing 5204 are then sleeved from top to bottom. The driven wheel 5202 and the upper sleeve 5211 are fixedly arranged. When the driven wheel 5202 rotates, the upper sleeve 5211 is driven to rotate. The lower end of the upper sleeve 5211 is fixedly connected to the lower sleeve 5208. Preferably, the inner wall of the lower sleeve 5208 is threadedly connected to the outer wall of the upper sleeve 5211. A through hole 5205 is provided on the side wall of the lower sleeve 5208. The lower end of the spring piece 5206 is bent and extends into the through hole 5205. The upper end is fixed to the lower sleeve 5208 by a ring 5210. When the skewer 91 of the skewer 9 is inserted from the end hole 5207 of the lower sleeve 5208, the lower end of the spring piece 5206 can tightly press against the skewer 91, thereby preventing the skewer 91 from slipping.

[0077] As in the first embodiment, the second embodiment also has a time prompt mechanism for detecting the insertion of the skewer 91 into the end hole 5207, timing the baking time, and reminding the completion of baking. The time prompt mechanism of the second embodiment includes a position sensor 5213, a trigger rod 5209, a time controller, a light-emitting diode 5212, etc. connected by a cable. The power supply and time controller are not shown in the figure. Specifically, Figure 11 The trigger rod 5209 has a T-shaped cross-section, with a larger lower end slidably disposed within the lower sleeve 5208. Its upper portion is in the shape of a straight rod and extends out of the upper sleeve 5211, corresponding to the position sensor 5213. The position sensor 5213 is fixed to the upper ring plate 4205. As for the choice of position sensor 5213, it can be capable of detecting the approach of the trigger rod 5209, such as a microswitch or Hall effect sensor. A microswitch is preferred for its simplicity and flexibility. When the trigger rod 5209 abuts, a trigger signal is generated and sent to the time controller, thereby starting the timer. The time controller's control of the light-emitting diodes 5212, as well as the number, type, and alternatives of the light-emitting diodes 5212, are similar to those of the first embodiment and will not be further described here.

[0078] It should be further noted that a light-emitting diode 5212 is positioned on the edge of the lower base plate 4203, corresponding to the skewer positioning mechanism 5200, to facilitate user confirmation of cooked skewers 9. The larger end of the trigger lever 5209 is preferably shaped to conform to the inner wall of the lower sleeve 5208, eliminating the need for a guide structure for its up-and-down movement. Because the lower end of the spring 5206 is bent and extends deep into the through-hole 5205, when the trigger lever 5209 falls, it will only slide to the bent position of the spring 5206 and will not slide out of the end hole 5207.

[0079] The upper end of the connecting tube plate 4204 is connected to the lower base plate 4203, and the lower end is connected to the heating source 8200. The power cable of the heating source 8200 is drawn out from the hollow cavity inside the support frame 3200 and the connecting rod 4206. Preferably, the connecting tube plate 4204 is connected to a partition 8201, and the heating source 8200 is fixed on the partition 8201. More preferably, the edge of the partition 8201 extends toward the inner wall of the door leaf 6200 to form a relatively sealed effect to prevent heat loss. More preferably, a plurality of notches (not marked) are provided on the edge of the partition 8201, and the position and number of the notches correspond one-to-one with the skewer positioning mechanism 5200.

[0080] When using the second embodiment, to open the door leaf 6200 , you can first insert the sticks 91 into all the end holes 5207 and then turn on the power, or turn on the power first, then open the door leaf 6200 and insert the sticks 91 into all the end holes 5207 .

[0081] When heating source 8200 is powered on, it begins to generate heat, heating skewers 9. Simultaneously, after skewer 91 is inserted into end hole 5207, the upper end of skewer 91 moves upward, driving trigger rod 5209 to move upward, triggering position sensor 5213. The time controller receives the trigger signal transmitted by position sensor 5213, starts timing, and green LED 5212 lights up.

[0082] During the baking process, the motor 7201 and the like operate, the output pulley 7203 rotates, and drives all the driven wheels 5202 to rotate through the transmission belt 7205, and all the skewer positioning mechanisms 5200 rotate, forming the effect of the skewer 9 rotating and heating evenly.

[0083] If it is necessary to move the position of some skewers 9 relative to the heating source 8200, the operating handle 4208 can be rotated to form a revolution effect.

[0084] When the set timer expires, red LED 5212 illuminates, and the user can open door 6200, remove skewers 91, and enjoy the skewers 9. LED 5212 then turns off. To continue grilling, a new skewer 91 can be inserted into the empty end hole 5207 of skewer positioning mechanism 5200, and door 6200 closed, continuing grilling until the skewers are cooked. In this second embodiment, motor 7201 is not braked during the grilling process. It should be understood that its speed is relatively low, and this does not cause any operational inconvenience.

[0085] Repeat this process.

[0086] like Figures 18-24 As shown, especially Figure 23As shown, from the overall external perspective, the portable barbecue device embodiment 3 provided by the present application mainly includes a base 1300, an oil receiving tray 2300, a support frame 3300, a top cover 4300, a skewer positioning mechanism 5300, and a door leaf 6300. In order to facilitate movement, a handle 4308 is also provided on the top of the top cover 4300. Preferably, the handle 4308 is in an inverted U shape, with both ends fixed to the top cover 4300. Further, as Figure 19 、 Figure 24 As shown, fasteners such as bolts pass through the top cover 4300 and are fixedly connected to the two pads inside it, and the pads are connected to the crossbeam 4301 described below.

[0087] In Example 3, the relative positions, connections, and primary functions of the base 1300, oil pan 2300, support frame 3300, top cover 4300, and door leaf 6300 are similar to those of Example 1 and will not be elaborated upon in detail. The hollow structure and function of the support frame 3300, the handle 6301 of the door leaf 6300, the deflector 6302 on the inner wall, the hinge 6303 connecting the door leaf 6300 and the support frame 3300, and the position sensor 6304 for detecting the opening / closing of the door leaf 6300 all have similar structures and functions as those in Example 1 and will not be further elaborated upon here.

[0088] like Figure 19 、 Figure 23 As shown, embodiment three includes an arc-shaped partition 6305, which is not described in embodiment one but can also be provided with the arc-shaped partition 6305. The arc-shaped guard plate 6305 is a narrow arc, one side of which is fixed to the inner wall of a corresponding door leaf 6300, and the other side is close to the skewers 9, and the height is slightly higher than the upper end of the heating source 8300, which can not only prevent heat loss, but also prevent hot air from flowing upward and damaging the driving mechanism, time prompt mechanism, etc. above.

[0089] The top cover 4300 is basically located at the top of the third embodiment, and is used to cover and protect the driving mechanism, transmission mechanism, control components, skewer positioning mechanism, time prompt mechanism, etc. set inside. The overall structure is also similar to a bowl-shaped structure with an opening downward.

[0090] For example Figure 19 、 Figure 20 、 Figure 24As shown, inside the top cover 4300, a crossbeam 4301 is connected to the upper end of the support frame 4300. This crossbeam 4301 provides a stable support base for multiple other components, such as the power output mechanism, multiple supporting connectors, the revolution drive mechanism, the rotation drive mechanism, etc., which directly or indirectly rely on the stable support of the crossbeam 4301. The power output mechanism includes not only a motor 7301, a reduction gear 7302, and an output gear 7103, but also a controller for controlling the operation of the motor 7301. The controller is not shown in the figure (because the technology used by the controller to control the motor is conventional technology), and the controller is connected to the aforementioned position sensor 6304. Its functions and effects are similar to those of the first embodiment and will not be repeated here.

[0091] Support connectors are a general term for a class of components, including the aforementioned crossbeam 4301, connecting rods 4304, 4305, spacers 4307, connecting rods 43011, connecting cylinders 4314, and several other unlabeled components, such as the base and corresponding fasteners that support motor 7301, reduction gear 7302, and output gear 7103. Various solutions resulting from different numbers, shapes, and locations of support connectors are considered within the scope of protection of this application.

[0092] To further elaborate, the crossbeam 4301 is in the shape of a flat rod, one end of which is fixed to the top of the support frame 3300, and at both ends of which are connected to the protective ring 4302 via a connecting rod 43011. The protective ring 4302 is annular, with a large hollow area in the middle for accommodating and passing the drive mechanism, etc., and the outer edge is close to the inner wall of the top cover 4300. Its function is similar to that of the first embodiment and will not be repeated here. The pad 4307 is approximately in the shape of a round pancake, and is fixed to the middle section of the crossbeam 4301 by a connecting rod 4304 formed by bolts. Its function is similar to that of the first embodiment and will not be repeated here. The power output mechanism of the third embodiment includes a motor 7301 fixed to the crossbeam 4301 via a connecting plate, a reduction gear 7302, an output gear 7303, a controller, etc. The motor 7301, the reduction gear 7302, and the output gear 7303 are connected in sequence. The connection method and the control of the motor by the controller are conventional technologies and will not be repeated here.

[0093] The revolution drive mechanism is used to drive the skewer positioning mechanism 5300 to rotate around the heating source 8300, specifically the skewers 9. The rotation drive mechanism is used to drive the skewer positioning mechanism 5300 to rotate. The revolution drive mechanism includes a rotating toothed disc 7304. The rotating toothed disc 7304 is disc-shaped, with teeth on its outer edge that mesh with the output gear 7303. Nuts secure multiple skewer positioning mechanisms 5300 to the inner side of the outer edge. As shown in the figure, one side of these nuts is provided with a position sensor 5313. Multiple skewer positioning mechanisms 5300 are distributed in a circular pattern below the rotating toothed disc 7304, surrounding its center. In the height direction, the rotating toothed disc 7304 is located below the pad 4307 and above the stationary toothed disc 7306. When the output gear 7303 drives the rotating toothed disc 7304 to rotate, the rotating toothed disc 7304 can rotate accordingly, thereby driving the multiple skewer positioning mechanisms 5300 installed thereon to rotate, creating a "revolution" effect. By doing so, the skewers 9 can pass through every position on the circumference of the heating source 8300. It should be noted that components of different heights that are stacked up and down can be separated by spacers, collars, plane bearings, etc. to reduce friction. Such structures are commonly used in the prior art and will not be described in detail here.

[0094] The self-rotation drive mechanism includes a passive gear 7305 and a stationary toothed disc 7306. The stationary toothed disc 7306 is stationary during use and its height is lower than the rotating toothed disc 7304. Ball bearings or the like can be set between the two to space them apart, thereby reducing friction and limiting their relative positions. The connecting rod 4305, which is similar to a bolt, has a large end at the bottom, and the threaded end passes through the stationary toothed disc 7306 and the rotating toothed disc 7304 that can rotate, and is then screwed into the pad 4307, which has multiple functions such as supporting the stationary toothed disc 7306 and the rotating toothed disc 7304. From this description, it can be seen that the revolution drive mechanism of embodiment three is similar to embodiment one, and utilizes an output gear to drive the rotating toothed disc to rotate, thereby driving all the skewers arranged thereon to revolve. The self-rotation drive mechanism is also similar to embodiment one, and utilizes a driven wheel (passive gear) fixedly connected to the skewers positioning mechanism to receive power, and the passive gear engages with a stationary toothed disc to achieve self-rotation.

[0095] The passive gear 7305 is fixedly connected to the upper sleeve of the skewer positioning mechanism 5300, and the two can rotate at the same time. Figure 19 、 Figure 24As shown, the skewer positioning mechanism 5300 of Example 3 is similar to Example 2, and reference may be made to the corresponding drawings of Example 2. It mainly includes a spring piece, an upper sleeve, a lower sleeve, a collar (there are no drawing marks in the drawings to make the drawings concise) and auxiliary gaskets, etc. The upper sleeve is a hollow cylindrical structure, and the upper end extends out of the rotating toothed disc 7304 and is fixedly connected by a nut. It should be emphasized that the nut does not fix the skewer positioning mechanism 5300 to the rotating toothed disc 7304, and cannot be fixed because the skewer positioning mechanism 5300 also needs to rotate, which is also the case with Example 1. The passive gear 7305 and the upper sleeve are fixedly arranged. When the passive gear 7305 rotates, the upper sleeve can be driven to rotate. The lower end of the upper sleeve is fixedly connected to the lower sleeve. Similar to Example 2, the inner wall of the lower sleeve can also be threadedly connected to the outer wall of the upper sleeve. A through hole is provided on the side wall of the lower sleeve, the lower end of the spring is bent and penetrates into the through hole, and the upper end is fixed to the lower sleeve by a ring. When the skewers 91 of the skewers 9 are inserted from the lower sleeve, the lower end of the spring can tightly press against the skewers, thereby preventing the skewers 91 from slipping.

[0096] Similar to other embodiments, the third embodiment is also provided with a time prompt mechanism. Preferably, the time prompt mechanism of the third embodiment includes a position sensor 5313, a trigger rod (not marked), a time controller, a light emitting diode 5312, etc. connected by a cable. The time controller is not shown. Because the trigger rod of the third embodiment and the position sensor 5313 used in conjunction with it are similar to those of the second embodiment, reference can be made to Figure 11 The trigger lever has a T-shaped cross-section, with a larger lower end slidably mounted in the lower sleeve and a straight upper portion extending out of the upper sleeve, corresponding to position sensor 5313. Position sensor 5313 is fixed to rotating toothed disc 7304. The number, type, and alternatives for the time controller, position sensor, and LEDs are similar to those in Example 1 and are not further described here.

[0097] It should be noted that the time prompt mechanism of the third embodiment requires external power supply, and the revolution drive mechanism continuously drives the multiple skewer positioning mechanisms to perform circular motion. In order to avoid cable entanglement, the third embodiment provides a new power supply scheme, which includes a conductive ring 5320 and a conductive contact 5321. The conductive contact 5321 is fixed to the crossbeam 4301 through a mounting seat (not marked). One end of the conductive contact 5321 is connected to the power supply cable, and the other end is in sliding contact with the conductive ring 5320 below. Preferably, the conductive contact 5321 is cylindrical and movably arranged in a deep hole in the above-mentioned mounting seat. A spring is provided at the upper end. The spring can drive the conductive contact 5321 to closely contact the conductive ring 5320 to avoid poor contact, obstruction of conduction, etc. The conductive ring 5320 is in a circular shape and is laid on the rotating gear disc 7304 around the rotation axis of the revolution drive mechanism. Devices that require electrical energy, such as a time controller, a light-emitting diode 5312 or a position sensor 5313, can be directly connected to the conductive ring 5320, thereby forming a circuit structure of power supply cables, conductive contacts 5312, conductive rings 5320, and electrical devices, and there will be no cable entanglement or twisting.

[0098] like Figure 24 As shown, the connecting tube 4314 extends from top to bottom to a height equivalent to the middle and lower portion of the door leaf 6300. The heating source 8300 is installed at the lower portion of the connecting tube 4314. The power cables required by the heating source 8300 are arranged from top to bottom, for example, along the middle cavity of the support frame 3300, the central through-hole of the cushion block 4307, the rotating gear disc 7304, the central hollow of the stationary gear disc 7303, and the connecting tube 4314. To prevent heat loss, the third embodiment also provides a partition 8301. The partition 8301 is located at the lower end of the connecting tube 4314 and is distributed in an annular shape, preferably with a double-layer structure.

[0099] When using this third embodiment, the power supply is turned on to supply power to the heating source 8300 and other electrical components; the door 6300 is opened, and the skewer 91 of the skewer 9 is inserted into the lower sleeve of the skewer positioning mechanism 5300. The skewer 91 triggers the position sensor 5313, and the green light-emitting diode 5312 is illuminated. Of course, the above two steps can be interchanged.

[0100] During the grilling process, the revolution drive mechanism rotates all skewers 9 around the heat source 8300, while the rotation drive mechanism rotates the skewer positioning mechanism 5300 of each skewer 9 around itself. The heat source 8300 radiates heat in all directions, causing grease and moisture from the skewers 9 to splatter and fall along the inner surface of the door leaf 6300 and the guide plate 6302 into the oil pan 2300.

[0101] When the predetermined baking time is reached, for example five minutes, the red LED 5312 lights up, and the user sees the prompt and opens the door 6300. The position sensor 6304 detects that the door 6300 is opened and sends the signal to the controller of the motor 7301 to control the braking of the motor 7301, making it easier to take out and put the skewers 9.

[0102] When the mature skewers 9 are removed, the light emitting diode 5312 goes out. When the fresh skewers are placed, the position sensor 5313 detects the new skewers, starts timing, and the green light emitting diode 5312 lights up.

[0103] When the door leaf 6300 is closed, the position sensor 6304 detects that the door leaf is closed and sends the trigger signal to the controller. The controller controls the motor 7301 and the transmission mechanism to operate and continue to drive the revolution drive mechanism and the rotation drive mechanism to rotate.

[0104] Repeat this process.

[0105] It should be emphasized that the above embodiments all include a skewer positioning mechanism, a revolution drive mechanism, a rotation drive mechanism, and a connection member, which enables the three to work together to form an integral device and an indispensable support and connection member. As for the specific composition of the three, there are multiple options. The support frame that provides support and connection for the three is not necessary. The heating source should not be considered necessary for this application. For example, charcoal, heating pipes, etc. can be provided as a heating source, and hooks can be provided to suspend the skewer positioning mechanism, revolution drive mechanism, rotation drive mechanism, etc. above the heating source. For this application, the shell is not necessary. Although the shell has the effects of heat preservation, preventing heat loss, preventing grease from splashing, and preventing dust from contaminating the skewers, it is not necessary to provide a shell when these effects are not considered. Obviously, if a shell is provided, a skewer storage space should be provided within the shell for the skewers. In other embodiments, the door leaf can form part of the shell, rather than the entirety of the above embodiments. For example, the shell is not continuous, but has a gap, and the door leaf can cover the gap, while still allowing the skewers to be taken in and out. In other words, the specific structure of the present application has more room for selection of technical means and is not limited to the above-mentioned multiple embodiments, but they should all be included in the scope of protection of the present application.

[0106] To sum up, the present application has multiple advantages: the revolution drive mechanism can make the skewers rotate around the heating source, and each skewer can be exposed to heat in every direction; the rotation drive mechanism can make the skewers move around themselves, and each position of each skewer can directly receive heat from the heating source; the skewer positioning mechanism can quickly and conveniently insert / remove the skewers without even stopping the machine; the time prompt mechanism can detect the baking time and issue a prompt, making the skewers taste more delicious, and so on.

[0107] It is understood from common technical knowledge that the present application may be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the embodiments disclosed above are merely illustrative in all respects and are not intended to be exclusive. All modifications that come within the scope of this application or are equivalent to the scope of this application are intended to be included in this application.
