Description

Technical Field

[0001] This utility model relates to the field of kitchenware technology, specifically a portable barbecue grill. Background Technology

[0002] When people travel outdoors or have team building activities during their leisure time, they often choose to picnic or camp outdoors, and barbecuing is a popular cooking method. Barbecuing involves heating and drying the air with fuel, and then placing food in the hot, dry air close to the heat source. Nowadays, the tools used for barbecuing, such as grills and barbecue stoves, are widely used.

[0003] Most barbecue grills on the market are one-piece grills, which are inconvenient to disassemble and assemble, take up a lot of space and are not easy to carry. Moreover, if a part is damaged during use, the entire product is scrapped.

[0004] To address the shortcomings of the aforementioned barbecue grills, a specific solution (hereinafter referred to as the "existing solution") was found through research: a portable barbecue grill disclosed in authorization announcement number CN222708085U includes a grill body, a support frame, and leg assemblies disposed on both sides of the support frame. The support frame and the grill body are detachably connected. The leg assemblies allow the barbecue grill to be folded and unfolded, facilitating user operation and saving space for easy transportation.

[0005] However, further research on this "existing solution" revealed that during the folding process, one end of the second leg needs to slide and engage with the support frame via a sliding component. Unfolding the second leg also requires operating the second leg support frame to slide and engage. This not only increases the number of steps, but also inevitably affects the folding and unfolding of the leg if components of the sliding component, such as the sliding piece and the sliding plate, get stuck. Furthermore, since the sliding component is installed at the bottom of the support frame, there needs to be a gap between the folded leg and the sliding component to prevent it from touching the sliding component. This will hinder further compression to make the overall size of the barbecue grill smaller after folding. Utility Model Content

[0006] The purpose of this invention is to provide a portable barbecue grill to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A portable barbecue grill includes a grill and a support frame, the support frame having a mounting area for the detachable grill; Support legs that can rotate with the support frame are installed on both sides of the support frame; The outrigger assembly includes two self-folding outriggers; The two legs are hinged to each other, and the top of the legs is hinged to the support frame.

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] In the description of this utility model, it should be noted that the terms "upper end," "lower end," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] Example 1 Please see Figure 1 , Figures 3 to 8 This utility model provides a technical solution: A portable barbecue grill includes a grill 1 and a support frame 2, the support frame 2 having a mounting area 24 for detachable grill 1; Support legs 3 that can rotate with the support frame 2 are installed on both sides of the support frame 2; The support leg 3 includes two self-folding support legs 3a; Two support legs 3a are hinged to each other, and the top of the support leg 3a is hinged to the support frame 2. One of the support legs 3a is equipped with a rotating wheel 5 and a vertical support 3c at the bottom, and the other support leg 3a is equipped with a support handle 3b with anti-slip texture at the bottom. A buffer cylinder 6 is also provided between the two outriggers 3a to help keep the first outrigger 3a1 and the second outrigger 3a2 relatively fixed.

[0043] In this embodiment, the vertical support 3c ensures the folded barbecue grill stands upright, preventing it from tipping over. The support handle 3b supports the first leg 3a1 when unfolded and also serves as a handle for the user to pull the folded portable barbecue grill. The rotating wheel 5 is a soft rubber roller with anti-slip texture. The soft rubber roller reduces noise and vibration during movement, while the anti-slip texture improves the anti-slip performance of the rotating wheel.

[0044] In this embodiment, the support leg 3 designed above enables the portable barbecue grill to be folded and unfolded, making it convenient for users and saving space for easy transportation. The adapter 4 effectively ensures the smoothness of the folding and unfolding of the support leg 3 of the portable barbecue grill, while the buffer cylinder 6 ensures the stability of the folding and unfolding process, avoiding the phenomenon of the support leg 3 pinching or hitting the user due to the rapid folding of the portable barbecue grill after unlocking.

[0045] In this embodiment, the support leg 3a is foldable. Specifically, the support leg 3a includes a first support leg 3a1 and a second support leg 3a2. The first support leg 3a1 and the second support leg 3a2 are hinged together by a transition part 4, and the transition part has a built-in stop lever 4e for keeping the first support leg 3a1 and the second support leg 3a2 relatively fixed.

[0046] The first leg 3a1 and the second leg 3a2 are rotated and fixed by the adapter 4. This not only keeps the first leg 3a1 and the second leg 3a2 in an unfolded and fixed state, but also releases the fixed state, so that the leg 3a can be further folded. Compared with the aforementioned "existing solution", the leg 3a does not need to slide relative to the support frame 2. Both legs 3a can be folded. At the same time, the first leg 3a1 and the second leg 3a2 of each leg 3a can be further self-folded. The folding operation is simple and convenient. Moreover, the portable barbecue grill occupies a smaller volume after being fully folded, making it easy to carry.

[0047] Specifically, such as Figures 4 to 8 As shown, the adapter 4 includes a rotating shaft housing 4a with an open slot and a circular adapter block 4b. The rotating shaft housing 4a is installed at the bottom end of the second leg 3a2, and the bottom end of the circular adapter block 4b is installed at the top end of the first leg 3a1. The top end of the circular adapter block 4b is located on the rotating shaft housing 4a and can rotate along the open slot. The gear lever 4e is used to hold the top end of the circular adapter block 4b to keep the first leg 3a1 and the second leg 3a2 relatively fixed. The rotating shaft housing 4a has a first rotating shaft 4c and a second rotating shaft 4d for mounting the circular adapter block 4b and the gear lever 4e, respectively. The top end of the circular adapter block 4b has a groove 4b1 for the gear lever 4e to enter and exit. A torsion spring 4g for the gear lever 4e to reset is mounted on the second rotating shaft 4d. The end of the rope 18 is connected to the top side of the gear lever 4e along the guide rod 4f inside the rotating shaft housing 4a.

[0048] like Figure 7 As shown, after the first leg 3a1 and the second leg 3a2 are deployed, under the action of the torsion spring 4g, the top of the shift lever 4e abuts against the inner wall of the top of the groove 4b1, serving as fulcrum y. Meanwhile, one end of the circular transition block 4b abuts against the bottom of the opening groove of the rotating shaft housing 4a, serving as fulcrum x. In this way, the rotation between the rotating shaft housing 4a and the circular transition block 4b can be restricted by the combined action of fulcrum x and fulcrum y. Thus, rotation between the second leg 3a2 and the first leg 3a1, which are respectively installed on the rotating shaft housing 4a and the circular transition block 4b, is impossible, thereby achieving the purpose of relative fixation / positioning.

[0049] Specifically, the support frame 2 is equipped with a lifting handle 17, which is used to pull the gear lever 4e through a rope 18 that passes through the second leg 3a2, so as to release the relative fixation between the first leg 3a1 and the second leg 3a2.

[0050] like Figure 6 As shown, when the support leg 3a needs to be folded, simply pull the rope 18 to overcome the holding force of the torsion spring 4g on the gear lever 4e. At this time, the gear lever 4e rotates in the direction of arrow B with the second pivot 4d as the center, so that the top of the gear lever 4e completely disengages from the inner wall of the top of the groove 4b1. Then, the circular transition block 4b can rotate in the direction of arrow C with the first pivot 4c as the center. This allows rotation between the pivot housing 4a and the circular transition block 4b, and thus rotation between the second support leg 3a2 and the first support leg 3a1, which are respectively installed on the pivot housing 4a and the circular transition block 4b, can also be achieved, thus achieving the purpose of folding.

[0051] In this embodiment, the gear lever 4e is strip-shaped or elliptical. The gear lever 4e is eccentrically mounted on the second rotating shaft 4d, and the circular adapter block 4b is eccentrically mounted on the first rotating shaft 4c. This facilitates the rotation of the gear lever 4e, so that the top of the gear lever 4e contacts the top of the groove 4b1 to form a fulcrum y, and facilitates the rotation of the circular adapter block 4b to abut against the bottom of the opening groove of the rotating shaft housing 4a to form a fulcrum x.

[0052] In this embodiment, the torsion spring 4g is mounted on the second rotating shaft 4d, with one end inserted into the pre-reserved insertion hole in the inner wall of the rotating shaft housing 4a and the other end inserted into the pre-reserved insertion hole on the gear lever 4e, thereby providing a force to make the top of the gear lever 4e abut against the top of the groove 4b1, and the gear lever 4e can be rotated and the tension removed after the gear lever 4e rotates to reset.

[0053] In this embodiment, as Figures 3 to 4 As shown, a lifting handle bracket 17b and a fixed bracket 2c are installed on the inner side of the support frame 2. The top end of the second leg 3a2 is hinged to the fixed bracket 2c. A lifting handle bracket groove 17c is provided on the lifting handle bracket 17b. The lifting handle 17 passes through the lifting handle bracket groove 17c via bolts, and a lifting handle washer 17a is installed thereon. The front end of the rope 18 is connected to the lifting handle washer 17a, and the end passes through the fixed bracket 2c and enters the second leg 3a2 through a rope hole pre-drilled on the inner side of the second leg 3a2. Then it rests on the guide rod 4f and finally connects to the top side of the gear lever 4e. Figure 4 As shown, pushing the lifting handle 17 to the left by hand pulls the rope 18, causing the rotating shaft housing 4a and the circular transition block 4b to rotate. This also allows rotation between the second leg 3a2 and the first leg 3a1, which are mounted on the rotating shaft housing 4a and the circular transition block 4b, respectively, achieving the folding purpose. Releasing the hand allows the lifting handle 17 to slide to the right via the rope 18 under the torsional force provided by the torsion spring 4g, thus returning it to its original position.

[0054] The fixed bracket 2c is in a "匚"-shape, on which an auxiliary reset spring 17d is installed, for the front end of the rope 18 to pass through and assisting the folding and subsequent unfolding and resetting of the rope 18. One end of the auxiliary reset spring 17d abuts against the fixed bracket 2c, and the other end is fixed to a fixing sleeve 18a fixedly sleeved on the rope 18.

[0055] Example 2 On the basis of Example 1, the following technical solution is further added: The cooker 1 comprises an upper cover 1a, a baking tray and a box body 1f. The box body 1f is installed inside the support frame 2 and located in the installation area, the upper cover 1a is hinged to the outer side of the support frame 2 through a hinge member 2d, the hinge member 2d is used for keeping the upper cover 1a hovering, and the baking tray is placed on the box body 1f.

[0056] In this embodiment, as shown in Figure 3 , Figure 9 and Figure 10 , the cooker 1 can realize the hovering of the upper cover 1a through cooperation with the hinge member 2d, which is convenient for users to use. The hinge member 2d can be a damping hinge. A user can open and close the upper cover 1a through the upper cover handle 1b. The baking tray is movably placed on the box body 1f.

[0057] The baking tray includes a detachable hollow barbecue plate 1c and a solid barbecue plate 1d. A series-connected combustion pipe with holes 15 is arranged directly below the baking tray, and a pot rack 16 is also arranged below the solid barbecue plate 1d; the series-connected combustion pipe penetrates through a part of the box body 1f to serve as a gas connection port 11. An igniter assembly is used for igniting the cooker 1, and specifically comprises an igniter switch 7 and an ignition pin 7a. The igniter switch 7 is installed on the inner side of the support frame 2 and is used for driving the ignition pin 7 to open and close. The ignition pin 7a is installed on the side face, close to the bottom, of the box body 1f, and is used for igniting the fuel gas overflowing from the holes 15 of the series-connected combustion pipe. A fuel gas ball valve 16 for controlling fuel gas overflowing from the corresponding series-connected combustion pipes below the hollow barbecue plate 1c and the solid barbecue plate 1d is installed on the side face, close to the bottom, of the box body 1f.

[0058] In this embodiment, as shown in Figure 13 , the box body 1f is used for installing the series-connected combustion pipe and the pot rack 16. The series-connected combustion pipe is coiled at the bottom of the box body 1f and on the periphery of the pot rack 16, fuel gas is supplied to the series-connected combustion pipe through the gas connection port 11, the fuel gas overflows from the holes 15, and then ignition and combustion can be realized by using the ignition pin 7. By rotating the fuel gas ball valve 12, fuel gas can be correspondingly supplied to the series-connected combustion pipe located below the hollow barbecue plate 1c, so as to realize ignition and fire extinguishing.

[0059] In this embodiment, after opening the top cover 1a, the food is placed on the baking tray: the perforated grilling tray 1c can be used to grill / smok the food, while the solid grilling tray 1d can be used to fry the food. If tea needs to be brewed, the solid grilling tray 1d can be removed separately, and the teaware or kettle can be placed on the pot rack 16 for heating. After closing the top cover 1a, the food on the baking tray can be braised or grilled. Therefore, in this embodiment, the stove 1 can function as both a grilling stove and a tea brewing stove, enabling the stove 1 to perform multiple functions such as frying, steaming, braising, and boiling. The area ratio of the perforated grilling tray 1c to the solid grilling tray 1d is 5:2, giving the baking tray a good division ratio to accommodate different processing methods for the food.

[0060] In this embodiment, as Figure 9 As shown, the bottom inner edge of the upper cover 1a has a pressure plate baking tray 1e, which is used to abut against the top edge of the box body 1f after the upper cover 1a is closed, thereby providing support for the upper cover 1a. Figure 10 As shown, by embedding a thermometer 19 on the upper cover 1a, users can easily and intuitively understand the specific temperature inside the stove 1 after the cover is closed.

[0061] In this embodiment, as Figure 4 As shown, a pressure relief valve 25 is installed at the bottom of the support frame 2. The pressure relief valve 25 is connected to the housing 1f through a pipe. When the upper cover 1a is closed to bake the food in the oven 1, if the gas pressure in the oven 1 is high, the pressure relief valve 25 can be used to relieve the pressure in the oven 1. The pressure relief valve 25 can be a manual pressure relief valve or an automatic electric pressure relief valve.

[0062] Example 3 Based on Embodiment 1 and / or Embodiment 2, the following technical solution is further added: like Figure 14 As shown, the support frame 2 has a shelf 2a and a handle 2b located on the side of the stove 1. The handle 2b is used to push and pull the shelf 2a to fold relative to the support frame 2, and the handle 2b is fixed to the support frame 2 by a positioning structure.

[0063] In this embodiment, the shelf 2a allows users to temporarily place seasonings or food during the grilling process. The shelf 2a is designed to be pull-out to expand its storage area. After the shelf 2a is pulled out or pushed back into place, a positioning structure ensures relative fixation between the shelf 2a and the support frame 2, preventing the shelf 2a from sliding on its own.

[0064] In this embodiment, as Figure 15As shown, the end of the handle 2b has a hollow insert 2f, the hollow cavity inside the support frame 2 has an anti-detachment rod 2i, the insert 2f is adapted to be inserted into the hollow cavity inside the support frame 2, and the side of the insert 2f has a moving groove 2g for the anti-detachment rod 2i to slide. The positioning structure includes a spring piece 2h located inside the insert 2f for abutting against the wall of the hollow cavity inside the support frame 2.

[0065] In this embodiment, when the shelf 2a needs to be removed, the handle 2b is pulled outwards, and the insert 2f can slide within the hollow cavity of the support frame 2. After being fully removed, the shelf 2a is fixed in place by the friction generated by the spring piece 2h pressing against the wall of the hollow cavity of the support frame 2, preventing it from moving on its own. The spring piece 2h is shaped like a "√" and is integrated with the insert 2f. The insert 2f also has a spring piece groove 2j, allowing a portion of the spring piece 2h to protrude into the spring piece groove 2j for pressing against the wall of the hollow cavity of the support frame 2.

[0066] In this embodiment, since the hollow cavity inside the support frame 2 has an anti-detachment rod 2i, and the side of the spring piece 2h has a strip-shaped moving groove 2g, the anti-detachment rod 2i cooperates with the moving groove 2g to achieve the purpose of preventing the shelf 2a from detaching. When the shelf 2a is not pulled out, there is a lower plate 2e with the same shape and size as the shelf 2a located directly above or below the shelf 2a. In this way, when the shelf 2a is pulled out, it can cooperate with the shelf 2a to expand the storage area and prevent condiments or food from falling out.

[0067] Example 4 Based on Example 3, the following technical solution is further added: The support frame 2 is equipped with a rotating handle 10, which is used to drive the first hook 8 to hook with the first locking piece 9 of the upper cover 1a, thereby achieving a fixed closing between the upper cover 1a and the box body 1f.

[0068] like Figure 2 As shown, turning the handle 10 to the left causes the first hook 8 to rotate, thereby disengaging from the first locking piece 9. This allows the upper cover 1a to be opened via the upper cover handle 1b. After closing the upper cover 1a, turning the handle 10 to the right causes the first hook 8 to rotate, thereby hooking onto the first locking piece 9. This keeps the upper cover 1a relatively fixed after it is closed.

[0069] Example 5 Based on Example 4, the following technical solution is further added: The bottom of the casing 1f is funnel-shaped / arc-shaped (i.e., the draft direction is downward), and has an oil drain 20 in the center. An oil tray bracket 21 is installed on the outer side of the bottom of the casing 1f, corresponding to the oil drain 20, and a tray 22 is inserted into the oil tray bracket 21. During the grilling or frying of food (such as meat) using the grill pan, excess oil or food grease will drip to the bottom of the casing 1f. Because the bottom of the casing 1f is funnel-shaped / arc-shaped, the excess oil or food grease easily flows down the sloping wall to the oil drain 20 under the action of gravity, and then drips into the tray 22 to collect, making it easy to pour the waste oil or grease into the trash can and avoid environmental pollution when using the portable barbecue grill outdoors.

[0070] In this embodiment, a hook 23 is installed on one side of the support frame 2 to facilitate hanging items.

[0071] Example 6 Based on Example 5, the following technical solution is further added: The support frame 2 is hinged with a second locking plate 13, and the first leg 3a1 is equipped with a second hook 14 that is used to hook with the second locking plate 13 after the leg 3a and the support frame 2 are folded.
