Description

Technical Field

[0001] This application relates to the field of barbecue equipment technology, and in particular to a small square box folding barbecue grill. Background Technology

[0002] Barbecue, as a popular cooking method, is not only favored at family gatherings but has also become an indispensable part of outdoor activities. The field of portable folding barbecue equipment technology has emerged to meet this need, aiming to satisfy people's desire to enjoy barbecue outdoors while solving the problems of large size and inconvenience in carrying traditional fixed barbecue equipment.

[0003] Related prior art, such as Chinese patent application "A Portable Barbecue Grill", application number: CN202420612044.9, discloses a grill comprising: a main support, the main support being box-shaped to form a barbecue cavity, the main support including side supports, the side supports having a plurality of evenly distributed grooves from top to bottom; a charcoal storage groove, the charcoal storage groove being disposed within the main support; a grilling net, the grilling net having inserts, the grilling net being fastened to the upper end of the main support by the inserts; a ash receiving plate, the ash receiving plate having retaining edges, the ash receiving plate being fastened to the lower end of the side supports by the retaining edges; and a support adjustment rod being inserted into the grooves to fix the charcoal storage groove to the main support, and the vertical position of the charcoal storage groove being adjusted by inserting the support adjustment rod into the grooves at different positions.

[0004] While existing portable folding barbecue equipment technology has achieved folding functionality to some extent, it still has many shortcomings. To further reduce the folded size, some grills employ complex folding structures and storage designs. While this achieves some reduction in size, it brings inconvenience to disassembly, storage, and assembly. For example, some grills require disassembling multiple parts one by one and placing them in specific storage containers, and then reassembling them requires following tedious steps. This complex process is not only time-consuming and labor-intensive, but also prone to damage to parts or assembly errors due to improper operation, causing inconvenience to users. This inconvenience is especially pronounced in outdoor environments where suitable tools and spaces are lacking. Utility Model Content

[0005] The technical problem to be solved by this application is to provide a small square box folding barbecue grill, which can be conveniently stored and unfolded through a bottom hinge structure, and is easy to disassemble and assemble, thus improving the ease of use.

[0006] The technical solution adopted in this application is as follows: a small square box folding barbecue grill, including a charcoal tray, a grill rack, a left shell and a right shell. The left shell and the right shell are arranged opposite each other, and the bottom of the left shell and the bottom of the right shell are hinged together. The structures of the left shell and the right shell are arranged symmetrically from left to right. The opposite surfaces of the left shell and the right shell are open. The front and rear sides of the charcoal tray are provided with waist-shaped holes. The charcoal tray is movably connected to the front and rear walls of the left shell or the right shell through a shaft that is movably installed in the waist-shaped holes. The grill rack is placed inside the charcoal tray. When the left shell and the right shell are closed, their interiors form a cavity that can accommodate the charcoal tray and the grill rack. When the left shell and the right shell are open, the charcoal tray and the grill rack are exposed.

[0007] Compared with existing technologies, the advantages of this application are as follows: First, the left and right shells are hinged at the bottom, allowing for simple opening and closing. This simple opening and closing action enables quick switching between "closed storage" and "open use" states, eliminating the need for cumbersome disassembly and assembly steps, thus improving ease of use. When closed, the two shells form a closed cavity that can completely accommodate the charcoal tray and grill rack, achieving rapid folding and storage of the overall structure, greatly reducing storage volume and making it easy to carry.

[0008] Secondly, the carbon disc is connected to the housing via a shaft installed in an oblong hole. This design allows the shaft to move left and right along the oblong hole, ensuring that the carbon disc is always stably mounted on the left and right housings. Whether in a "closed storage" or "open use" state, the carbon disc does not need to be disassembled or reassembled, making it very convenient for users.

[0009] Finally, the left and right shells adopt a symmetrical structural design, which reduces the types of parts, lowers the complexity and cost of mold development and manufacturing, and also makes it easier for users to understand and operate.

[0010] In some embodiments of this application, the opposing surfaces of the left and right housings are both planes. The left and right housings are rotated around the hinge axis until the opposing surfaces of the left and right housings are in contact, which is the closed state of the left and right housings. The planar design ensures that the left and right housings and the right housing can fit tightly together when closed, effectively reducing the storage volume, preventing dust from entering, and the structure is simple and reliable.

[0011] In some embodiments of this application, the bottom surfaces of the left and right housings include a first placement surface and a second placement surface, with one side of the first placement surface connected to the second placement surface, and the included angle between the first and second placement surfaces being an obtuse angle. The obtuse angle design of the bottom surface provides a more stable support structure when unfolded for use, increases the contact area with the ground, and prevents the barbecue grill from tipping over.

[0012] In some embodiments of this application, the other side of the second placement surface of the left shell is hinged to the other side of the second placement surface of the right shell. The opposite surface of the left shell is perpendicular to the first placement surface, and the opposite surface of the right shell is perpendicular to the first placement surface. This application provides the outer surfaces of the left and right shells with preset structures and angles, which can well adapt to the usage scenarios of the barbecue grill. The first placement surface serves as a support surface in the folded state, allowing the folded product to be placed independently and stably, facilitating storage and transportation.

[0013] In some embodiments of this application, the top surfaces of the left and right shells are inclined surfaces, and the two sides of the second placement surface are respectively connected to the first placement surface and the top surface; two foot pads are provided on the first placement surface. The inclined top surface design can support the side support walls of the grill rack and charcoal plate when unfolded as a barbecue grill.

[0014] In some embodiments of this application, the angle between the second placement surface and the top surface is greater than or equal to 90 degrees, and the second placement surface and the top surface have multiple elongated air vents. This angle ensures that the interior of the housing has a sufficiently large accommodating space to conveniently accommodate components such as the carbon tray and grill.

[0015] In some embodiments of this application, the top of the opposite surfaces of the left and right shells are provided with a plurality of slots for inserting a grill rack. The grill rack is composed of crisscrossing connecting rods, with a plurality of connecting rods extending to the left and right sides of the grill rack to form support rods. The support rods correspond one-to-one with the slots, and the grill rack is mounted on the left and right shells via the support rods and the slots. Through the cooperation of the support rods and the slots, the grill rack can be quickly installed, positioned, and disassembled, with simple operation and stable and reliable connection.

[0016] At this time, the grill is in use, with the charcoal plate located inside the left and right shells and below the grill.

[0017] In some embodiments of this application, the grill comprises a first frame and a second frame with identical structures joined together; when not in use, the first and second frames are stored inside the carbon tray. The modular design reduces the volume of individual parts, making them easier to store inside the carbon tray, optimizing storage space utilization, and resulting in a more compact overall structure after folding.

[0018] In some embodiments of this application, the front and rear sides of the left and right housings are both planar, and the oblong holes on the carbon disc are horizontally arranged. When the left and right housings are closed, the shaft is located at the ends of the two oblong holes that are far apart from each other; when the left and right housings are open, the shaft is located at the ends of the two oblong holes that are close to each other. The design of the oblong holes and the shaft allows the carbon disc to automatically adjust its position during the opening and closing of the housings, reliably switching between storage and use states without manual disassembly, and always maintaining connection.

[0019] In some embodiments of this application, a handle is provided on the top of the outer side of the left housing, and a handle is provided on the top of the outer side of the right housing. Users can lift the folded barbecue grill using both handles, improving portability.

[0020] Based on common knowledge in the field, the above-described embodiments can be combined arbitrarily. Attached Figure Description

[0024] The present application will now be described in detail with reference to the accompanying drawings.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] Small square box folding barbecue grill, as shown in Example 1 Figures 1 to 4As shown, the device includes a carbon tray 1, a grill rack 2, a left shell 3, and a right shell 4. The left shell 3 and right shell 4 are positioned opposite each other, with the bottom of the left shell 3 hinged to the bottom of the right shell 4. The structures of the left shell 3 and right shell 4 are symmetrically arranged, reducing the types of parts and lowering the complexity and cost of mold development and manufacturing, while also facilitating user understanding and operation. The opposite surfaces of the left shell 3 and right shell 4 are open. The carbon tray 1 has oblong holes 5 on both its front and rear sides. The carbon tray 1 is movably connected to the front and rear walls of the left shell 3 or right shell 4 via a shaft 6 that is movably installed in the oblong holes 5. The grill rack 2 is placed inside the carbon tray 1. This design allows the shaft 6 to move left and right along the oblong holes 5, ensuring that the carbon tray 1 is always stably installed on the left shell 3 and right shell 4. Whether in a "closed storage" state or an "open use" state, the carbon tray 1 does not need to be disassembled or reassembled, making it very convenient for users. When the left shell 3 and right shell 4 are closed, their interiors form a cavity that can accommodate the charcoal tray 1 and the grill rack 2; when the left shell 3 and right shell 4 are open, the charcoal tray 1 and the grill rack 2 are exposed. The left shell 3 and right shell 4 are hinged at the bottom for easy opening and closing. This simple opening and closing action allows for quick switching between "closed storage" and "open use" modes, eliminating the need for cumbersome disassembly and assembly, thus improving ease of use. When closed, the two shells form a closed cavity that can completely accommodate the charcoal tray 1 and the grill rack 2, achieving rapid folding and storage of the entire structure, greatly reducing its storage volume and making it easy to carry.

[0027] Example 2, as Figures 1 to 4 As shown, the opposing surfaces of the left shell 3 and the right shell 4 are both planes. The left shell 3 and the right shell 4 are closed when rotated around the hinge axis until the opposing surfaces of the left shell 3 and the right shell 4 are in contact. The planar design ensures that the left and right shells 4 and the right shell 4 can fit tightly together when closed, effectively reducing the storage volume, preventing dust from entering, and the structure is simple and reliable.

[0028] The bottom surfaces of the left shell 3 and the right shell 4 include a first placement surface 8 and a second placement surface 9. One side of the first placement surface 8 is connected to the second placement surface 9, and the included angle between the first placement surface 8 and the second placement surface 9 is an obtuse angle. The obtuse angle design of the bottom surface provides a more stable support structure when unfolded and used, increases the contact area with the ground, and prevents the barbecue grill 2 from tipping over.

[0029] The other side of the second placement surface 9 of the left shell 3 is hinged to the other side of the second placement surface 9 of the right shell 4. The opposite surface of the left shell 3 is perpendicular to the first placement surface 8, and the opposite surface of the right shell 4 is perpendicular to the first placement surface 8. This application provides the outer surfaces of the left shell 3 and right shell 4 with preset structures and angles, which can well adapt to the usage scenarios of the barbecue grill 2. The first placement surface 8 serves as a support surface in the folded state, allowing the folded product to be placed independently and stably, facilitating storage and transportation.

[0030] The top surfaces of the left shell 3 and the right shell 4 are inclined surfaces, and the two sides of the second placement surface 9 are respectively connected to the first placement surface 8 and the top surface; two foot pads 16 are provided on the first placement surface 8. The inclined top surface design can support the side support walls of the grill rack 2 and the charcoal plate 1 when unfolded as a barbecue grill.

[0031] The angle between the second placement surface 9 and the top surface is greater than or equal to 90 degrees, and the second placement surface 9 and the top surface have multiple narrow air vents 15. This angle ensures that the interior of the housing has a sufficiently large capacity to conveniently accommodate components such as the carbon tray 1 and the grill 2.

[0032] The top of the opposite surfaces of the left shell 3 and the right shell 4 are provided with several slots 10 for inserting the grill rack 2. The grill rack 2 is composed of crisscrossing connecting rods, with several connecting rods extending to the left and right sides of the grill rack 2 to form support rods 11. The support rods 11 correspond one-to-one with the slots 10. The grill rack 2 is mounted on the left shell 3 and the right shell 4 through the support rods 11 and the slots 10. The cooperation between the support rods 11 and the slots 10 enables the grill rack 2 to be quickly installed, positioned, and disassembled, with simple operation and stable and reliable connection.

[0033] At this time, the grill 2 is in use, and the charcoal plate 1 is located inside the left shell 3 and the right shell 4, and is located below the grill 2.

[0034] The grill 2 consists of a first frame 12 and a second frame 13 with identical structures joined together. When not in use, the first frame 12 and the second frame 13 are stored inside the carbon tray 1. The modular design reduces the volume of individual parts, making them easier to store inside the carbon tray 1, optimizing storage space utilization, and making the overall structure more compact after folding.

[0035] The front and rear sides of the left housing 3 and right housing 4 are both flat, and the oblong holes 5 on the carbon disc 1 are horizontally arranged. When the left housing 3 and right housing 4 are closed, the shaft 6 is located at the ends of the two oblong holes 5 that are far apart from each other; when the left housing 3 and right housing 4 are open, the shaft 6 is located at the ends of the two oblong holes 5 that are close to each other. The matching design of the oblong holes 5 and the shaft 6 allows the carbon disc 1 to automatically adjust its position during the opening and closing of the housings, reliably switching between storage and use states without manual disassembly, and always maintaining connection.

[0036] A handle 14 is provided on the top of the outer side of the left shell 3, and a handle 14 is provided on the top of the outer side of the right shell 4. Users can lift the barbecue grill 2 when it is closed by using the two handles 14, which improves the convenience of carrying it.
