Abstract
Description
Technical Field
[0001] This utility model relates to the field of air fryer technology, and in particular to a handle structure for an air fryer. Background Technology
[0002] Air fryers primarily use air instead of hot oil in a frying pan, employing convection and a mechanical fan to circulate hot air rapidly around the food to cook it. Due to their convenience—simply setting different temperatures and times to cook food—air fryers have become a very common household appliance. The main components of an air fryer include the outer shell, with a heating element at the top and a pull-out inner pot at the bottom. Currently, most air fryers have a panel on the outside of the inner pot, with a handle attached to the panel for pulling the inner pot out. However, the handle is usually fixed to the panel, making it quite obtrusive relative to the outer shell. During packaging, a single handle occupies a significant amount of space, increasing the overall packaging size, leading to higher packaging costs, a substantial decrease in convenience, and a corresponding increase in transportation costs. Utility Model Content
[0003] The purpose of this invention is to design a handle structure for an air fryer to address the shortcomings of the aforementioned technologies.
[0004] This utility model designs a handle structure for an air fryer, including a handle, an inner pot, and a fixing part. The handle has an insertion end, and the fixing part is connected to the outside of the inner pot. The fixing part has a mounting hole. The insertion end has a shaft perpendicular to the end face of the insertion end. The shaft is inserted into and rotatably connected to the mounting hole. The peripheral wall of the shaft has at least two protrusions arranged in a ring array. A limiting plate is provided in the mounting hole. The limiting plate has a positioning hole that is coaxial with and communicates with the mounting hole. The axial cross-section of the shaft and the protrusions is adapted to the shape of the positioning hole, so that the shaft and the protrusions can pass through the positioning hole simultaneously. The inner wall of the mounting hole has a protrusion corresponding to the protrusion in front of the limiting plate. Each protrusion has a positioning groove. When the shaft is rotated until each protrusion is misaligned with the positioning hole, each protrusion and the positioning groove on the corresponding protrusion form a limiting position, so that the handle is connected to the fixing part.
[0005] Preferably, the protrusion has a guide groove on one side of the positioning groove, and the guide groove and the positioning groove are smoothly transitioned to guide the protrusion to rotate into the positioning groove.
[0006] In a further optimization, the protrusion is provided with a limiting groove on the other side of the positioning groove to prevent the protrusion from rotating excessively.
[0007] Further optimization involves providing two symmetrically distributed protrusions on the peripheral wall of the shaft, and correspondingly, two protrusions, each of which is provided with a positioning groove, a guide groove, and a limiting groove.
[0008] Preferably, the protrusion is integrated with the shaft.
[0009] Preferably, the fixing part includes a connecting plate and a panel, the connecting plate being located between the inner liner and the panel, the connecting plate being connected to the outside of the inner liner, and the panel being connected to the outside of the connecting plate.
[0010] Further optimization involves providing a first mounting position on the surface of the connecting plate and a second mounting position on the surface of the panel, with the first mounting position and the second mounting position connected by fasteners.
[0011] Further optimization involves providing a first snap-fit portion on the surface of the connecting plate, and a second snap-fit portion on the surface of the panel that engages with the first snap-fit portion.
[0012] Further optimization involves having two first locking parts, symmetrically distributed in the central area of the connecting plate and located on both sides of the handle.
[0013] Further optimization involves bending the edge of the connecting plate to form an end face, covering the end face with the panel, forming a cavity between the panel and the connecting plate, and providing heat dissipation holes communicating with the cavity on both the upper and lower end faces of the connecting plate.
[0014] The technical advantage of this utility model is that the top of the handle is inserted into the mounting hole of the fixing part as the insertion end. The fixing part is connected to the side of the inner liner. The inner wall of the mounting hole is provided with a protrusion and a positioning groove. The insertion end is provided with a shaft. The peripheral wall of the shaft is provided with symmetrically distributed protrusions. The shaft is rotatably connected to the mounting hole. When the shaft rotates until the protrusion and the positioning groove on the inner wall of the mounting hole cooperate with each other, the handle is fixedly connected to the fixing part. The protrusion limits the protrusion and prevents the handle from continuing to rotate in the same direction. When the handle rotates in the opposite direction, the protrusion and the positioning groove separate. At this time, the handle can be detached from the mounting hole. Therefore, the handle can be detachably connected. It is not only simple in structure and easy to implement, but also convenient for packaging and transportation, and easy to manufacture.

Detailed Implementation
[0023] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0024] This embodiment provides a handle structure for an air fryer, including a handle 1, an inner pot 2, and a fixing part 3. One end of the handle 1 has an insertion end 11. In this embodiment, the insertion end 11 is a cylindrical end. The fixing part 3 is connected to the outside of the inner pot 2. The fixing part 3 has a mounting hole 31. The insertion end 11 has a shaft 111. The shaft 111 is vertically inserted into the mounting hole 31. After the shaft 111 is inserted, it is rotatably connected to the mounting hole 31. The shaft 111 and the mounting hole 31 are limited by a limiting structure, thereby realizing a detachable connection between the handle 1 and the fixing part 3, which facilitates the installation and removal of the handle 1. At the same time, it makes the processing and manufacturing more convenient, without the need for the handle 1 and the fixing part 3 to be integrally formed.
[0025] Specifically, the limiting structure includes at least two protrusions 112 on the peripheral wall of the portion of the shaft 111 that extends into the mounting hole 31. These protrusions 112 are arranged in a ring array on the outer peripheral wall of the shaft 111. In this embodiment, the protrusions 112 are located on the outer peripheral wall of the top end of the shaft 111, and there are two protrusions 112 symmetrically distributed on the outer peripheral wall of the top end of the shaft 111. The protrusions 112 are integrally designed with the shaft 111, meaning they extend from the outer surface of the shaft 111. The mounting hole 31 has a certain depth. A radial limiting plate 32 is provided on the inner wall of the mounting hole 31. The limiting plate 32 has a positioning hole 33 that is coaxial with and communicates with the mounting hole 31. The axial cross-sections of the shaft 111 and the protrusion 112 are adapted to the shape of the positioning hole 33, meaning that the shaft 111 and the protrusion 112 can pass through the positioning hole 33 simultaneously. In this embodiment, since the two protrusions 112 are located on both sides of the shaft 111, forming a waist-like shape, the positioning hole 33 is also similar in shape to a waist-shaped hole to allow the shaft 111 and the protrusion 112 to pass through. 2. A protrusion 34 is provided on the inner wall of the mounting hole 31 in front of the limiting plate 32. The protrusion 34 usually corresponds one-to-one with the protrusion 112. Each protrusion 34 has a positioning groove 35. When the shaft 111 and the protrusion 112 pass through the positioning hole 33, the top of the shaft 111 and the protrusion 112 are at the protrusion 34. At this time, the shaft 111 is rotated so that the protrusion 112 is misaligned with the positioning hole 33, and the protrusion 112 rotates into the positioning groove 35 on the corresponding protrusion 34. 5. A radial limit is formed, that is, the protrusion 112 is snapped into the positioning groove 35. At the same time, after the protrusion 112 rotates, it forms an axial limit with the limiting plate 32 to prevent the shaft 111 and the protrusion 112 from retracting and separating from the mounting hole 31. In addition, the end face of the insertion end 11 at the end where the shaft 111 is located also forms an axial limit on the shaft 111, which can prevent the shaft 111 and the protrusion 112 from continuing to be inserted. Finally, the handle 1 is detachably connected to the fixing part 3, and the stability of the handle 1 when connected is guaranteed.
[0026] The protrusion 34 has a guide groove 36 on one side of the positioning groove 35 and a limiting groove 37 on the other side of the positioning groove 35. That is, the guide groove 36 and the limiting groove 37 are located on opposite sides of the positioning groove 35, with a smooth transition between them. The guide groove 36 is an arc-shaped groove. When the shaft 111 rotates, the protrusion 112 enters the positioning groove 35 along the guide groove 36. One side of the guide groove 36 connects to the positioning groove 35, while the other side protrudes from the protrusion 34. The limiting groove 37 connects to the positioning groove 35 on one side and forms a certain angle with the surface of the protrusion 34 on the other side, radially limiting the protrusion 112. When the protrusion 112 fits into the positioning groove 35... Then, when rotating in the same direction, the limiting groove 37 forms a radial limit on the protrusion 112, so that the protrusion 112 will not continue to rotate in the same direction, that is, to prevent the protrusion 112 from rotating excessively along the protrusion 34. At this time, a fixed installation is formed between the handle 1 and the fixing part 3. Since the guide groove 36 and the positioning groove 35 are smoothly transitioned, when the shaft 111 rotates in the opposite direction, the protrusion 112 moves along the guide groove 36 until the shaft 111 rotates until the shaft 111 and the protrusion 112 are aligned with the positioning hole 33. Then the shaft 111 and the protrusion 112 can be pulled out from the positioning hole 33, that is, the insertion end 11 of the handle 1 can be separated from the mounting hole 31, realizing the disassembly of the handle 1.
[0027] It should be noted that the guide groove 36, the positioning groove 35, and the limiting groove 37 are connected in sequence. When the protrusion 112 rotates to form a latch with the guide groove 36, the guide groove 36 and the limiting groove 37 limit the protrusion 112 to a certain extent, so that the protrusion 112 can be stably latched in the positioning groove 35. The connecting surfaces of the guide groove 36, the positioning groove 35, and the limiting groove 37 are all smooth, so that the protrusion 112 can rotate smoothly in both directions, while also creating a certain damping sensation when the handle 1 is rotated.
[0028] Furthermore, the fixing part 3 includes a connecting plate 38 and a panel 314. The connecting plate 38 is located between the inner liner 2 and the panel 314. The connecting plate 38 is connected to the outside of the inner liner 2. The inner liner 2 has a cylindrical structure. The inner sidewall of the connecting plate 38 is adapted to the shape of the outer wall of the inner liner 2. The surface of the connecting plate 38 is provided with a first mounting position 39, and the surface of the panel 314 is provided with a second mounting position 315. In this embodiment, both the first mounting position 39 and the second mounting position 315 are threaded posts. The first mounting position 39 and the second mounting position 315 are connected by threaded fasteners. There are four first mounting positions 39, which are located at the four ends of the connecting plate 38 respectively. The second mounting positions 315 are also located at the four ends of the panel 314 respectively, so as to ensure the stability of the panel 314 and the connecting plate 38 after connection.
[0029] The inner liner 2 has a through hole on its side wall, and the connecting plate 38 has a corresponding through hole. The two through holes are connected and fixed by threaded fasteners to achieve the fixed installation of the inner liner 2 and the connecting plate 38.
[0030] Panel 314 is connected to the outside of connecting plate 38. In this embodiment, the edge of connecting plate 38 is bent to form an end face, and panel 314 covers the end face to form a connection. A cavity 317 is formed between panel 314 and connecting plate 38 after connection. The upper end face 311 and lower end face 312 of connecting plate 38 are provided with heat dissipation holes 313 that communicate with cavity 317, which facilitates heat dissipation between connecting plate 38 and panel 314, and also has a certain heat insulation effect to prevent panel 314 and handle 1 from getting too hot.
[0031] The surface of the connecting plate 38 is also provided with a first snap-fit portion 310, which is a post 3101. The post 3101 is located on the side of the connecting plate 38 facing the panel 314. The post 3101 has a square hole 3103 on its side, which extends to the side of the connecting plate 38 facing the inner liner 2. The side wall of the square hole 3103 forms an opening 3102. The surface of the panel 314 is provided with a second snap-fit portion 316, which is a square block 3161. The top of the square block 3161 is a snap-fit block 3162 that protrudes laterally. When the connecting plate 38 and the fixing plate are connected, the snap-fit block 3162 is inserted from the opening 3102 into the square hole 3103 and forms a snap-fit with the top surface of the square hole 3103, thereby realizing the interlocking of the first snap-fit portion 310 and the second snap-fit portion 316.
[0032] In addition, there are two first snap-fit parts 310, which are symmetrically distributed in the central area of the connecting plate 38 and located on both sides below the handle 1, so that the connection between the panel 314 and the connecting plate 38 is more stable.
[0033] In another embodiment, when there are two or more protrusions 112, they are arranged in a ring array along the periphery of the shaft 111. The number of protrusions 34 corresponds one-to-one with the number of protrusions 112. Each protrusion 34 is provided with a positioning groove 35, a guide groove 36 and a limiting groove 37. At this time, when the shaft 111 together with the protrusions 112 is inserted into the mounting hole 31 and passes through the positioning hole 33, the shaft 111 is rotated, the protrusions 112 are misaligned with the positioning holes 33 and the protrusions 112 slide into the positioning groove 35 of the corresponding protrusion 34 to form a latch.
[0034] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
