[0035] Reference Figures 1-11 A foldable stove includes a burner head 1, an air inlet pipe 2 installed at the lower end of the burner head 1, a fixing frame 3 sleeved on the air inlet pipe 2, and at least three regularly arranged connecting plates 4 and a number of support frames 5 equal to the number of connecting plates 4. The number of connecting plates 4 and support frames 5 is the same, preferably three, and they are evenly distributed. Each connecting plate 4 extends radially out of the outer wall of the burner head 1, forming a space 6 between the bottom surface of the burner head 1 and the connecting plate 4 for the connecting plate 4 to rotate. Each support frame 5 includes an upper support plate 51 and a lower support plate 52. The upper support plate 51 is used to support the cookware, and the lower support plate 52 is used to contact the load-bearing surface and support the burner head 1. The support is located away from the load-bearing surface, which can be the ground, tabletop, countertop, etc. The first end 41 of the connecting plate 4 is rotated and fixed to the fixing frame 3 through the first limiting member 7. The second end 42 of the connecting plate 4 is rotated and fixed to the support frame 5 through the second limiting member 8. In the unfolded state, the connecting plate 4 and the support frame 5 are roughly perpendicular to the load-bearing surface, and each support frame 5 is regularly erected around the burner head 1. When folded, the connecting plate 4 is rotated, and the connecting plate 4 and the support frame 5 are roughly parallel to the load-bearing surface. The support frame 5 is flipped towards the burner head 1 and folded under the connecting plate 4 for storage.

[0036] When the stove is in the unfolded state, the connecting plate 4 and the support frame 5 are roughly perpendicular to the load-bearing surface. One end of the connecting plate 4 is fastened to the fixing frame 3, and the other end is fastened to the support frame 5 to prevent the connecting plate 4 and the support frame 5 from rotating. At this time, multiple support frames 5 are evenly distributed around the stove head 1. The bottom of each support frame 5 is used to place on the load-bearing surface to support the stove. The top of each support frame 5 is used to support the cookware. When the stove head 1 is burning, it heats the cookware located above it.

[0037] When this stove is in its folded storage state, first loosen the first limiting piece 7, rotate the connecting plate 4 90 degrees clockwise so that the connecting plate 4 and the support frame 5 are roughly parallel to the load-bearing surface, then tighten the first limiting piece 7 to secure one end of the connecting plate 4 to the fixing frame 3; then loosen the second limiting piece 8, rotate the support frame 5 to fold it under the connecting plate 4 for storage, reducing its volume; then tighten the second limiting piece 8 to secure the other end of the connecting plate 4 to the support frame 5; at this point, the bottom surface of the burner head 1, the connecting plate 4, the support frame 5, and the load-bearing surface are roughly horizontal; this application can quickly unfold to heat cookware such as pots, bowls, and basins, and can also quickly fold to reduce its volume, making it easy to store, convenient to use, and highly applicable.

[0038] In some embodiments, a fixing plate 43 is correspondingly bent at the first end 41 of the connecting plate 4 and the fixing frame 3, and the two fixing plates 43 can be detachably connected by a first limiting member 7; a connecting plate sleeve 44 is formed at the second end 42 of the connecting plate 4; a support frame slot 53 is provided in the middle of the support frame 5, and the connecting plate sleeve 44 is inserted into the support frame slot 53, and the two can be detachably connected by a second limiting member 8; the two correspondingly bent fixing plates 43 form a clamping connection interface, and frictional damping is generated by the tightening force of the first limiting member 7 (such as a bolt and nut) to achieve adjustable angle fixation between the connecting plate 4 and the fixing frame 3; the connecting plate sleeve The tube 44 and the support frame slot 53 adopt a transition fit, which ensures smooth assembly and avoids shaking; the second limiting member 8 passes through the sleeve and locks after slotting, forming a three-point force structure (both sides of the sleeve + center of the limiting member), which improves bending strength; 70% of the weight is directly transferred to the ground by the support frame 5, and 30% is distributed to the fixed frame 3 through the connecting plate 4, reducing local stress concentration; the first limiting member 7 adopts a nylon locking nut to maintain preload in a vibration environment; the V-shaped guide surface of the support frame slot 53 allows the connecting plate sleeve 44 to be automatically centered and positioned under gravity; this application only needs to tighten or loosen two limiting members to complete folding or unfolding.

[0039] In some embodiments, the support frame 5 includes a plate 54, with an upper support plate 51 and a lower support plate 52 correspondingly disposed at both ends of the plate 54; the upper support plate 51 has a plurality of anti-slip grooves 511 arranged side by side on its top; the plate 54 has a plate notch 541 located between the upper support plate 51 and the lower support plate 52; the upper support plate 51 and the lower support plate 52 have a plurality of heat dissipation and weight reduction holes 512; the upper support plate 51 (cookware contact surface) adopts a gradually changing thickness design (3mm→5mm), and the serrated structure of the anti-slip grooves 511 converts the weight of the cookware into a multi-point distributed load; the plate 54 serves as the main load-bearing beam, and its notch 541 forms a stress guiding channel; the above structure can achieve technical effects such as anti-slip, weight reduction, and heat dissipation.

[0040] In some embodiments, both the first limiting member 7 and the second limiting member 8 include a threaded fastener 71 and a nut 72. To improve stability, a gasket can also be fitted. The threaded fastener 71 and the nut 72 generate an axial preload by tightening, which creates a strong frictional constraint between the contact surface of the connecting plate 4 and the fixing frame 3 / support frame 5. The addition of the gasket can disperse the pressure and prevent loosening.

[0041] In some embodiments, a detachable shelf 9 is also included. At least three U-shaped positioning seats 91 are regularly arranged on the outer wall of the shelf 9, the number of which corresponds to the support frame 5. The shelf 9 is placed flat on top of each upper support plate 51, and the U-shaped positioning seats 91 are upside down on the upper support plate 51 to prevent them from falling off. The upside-down structure of the U-shaped positioning seats 91 uses gravity to generate a self-tightening effect, forming a two-way constraint with the upper support plate 51 (preventing lifting in the vertical direction and preventing displacement in the horizontal direction). Installation is completed by simply placing it flat. The elastic deformation of the U-shaped opening is small, which takes into account both tightness and ease of operation. This structure can be adapted to cookware of different diameters.

[0042] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
