[0030] The present application is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments are only specific descriptions of the present application, and their purpose is to allow those skilled in the art to better understand the technical solution of the present application, and should not be regarded as limiting the present application.

[0032] Embodiment 1:
[0033] The present application embodiment discloses a cooking device, such as Figure 1 and Figure 2As shown, it comprises an upper shell 1 and a lower shell 2, wherein the upper shell 1 is buckled on the lower shell 2; a reflector 11 with its opening facing downward and a hot air circulation assembly 12 located in the reflector 11 are arranged in the upper shell 1, wherein the hot air circulation assembly 12 comprises a heating element 121, a fan blade 122 and a driving motor 123 for driving the fan blade 122 to rotate. The lower shell 2 comprises an outer shell 21 with an opening on the front side and a bottom shell 22 located at the bottom of the outer shell 21 and connected to the outer shell 21, an inner lining 23 with an opening on the front side is arranged in the outer shell 21, and a bottom plate 24 connected to the inner lining 23 is correspondingly arranged on the bottom shell 22, and a pot assembly 25 is arranged in the lower shell 2, wherein the pot assembly 25 comprises a pot body and a handle, and the pot body is inserted into the lower shell 2 through the opening on the front side, and the reflector 11 and the pot assembly 25 form a cooking space.
[0034] An isolation bracket 3 is also provided in the lower shell 2. The isolation bracket 3 is made of high temperature resistant plastic material, such as PP, ABS, PC, etc. The top surface of the isolation bracket 3 is higher than the top surface of the bottom plate 24. The pot body assembly 25 is placed in the lower shell 2 through the opening, and the bottom of the pot body 251 is in conflict with the isolation bracket 3. Although the isolation bracket 3 made of plastic material has excellent wear resistance, corrosion resistance, high temperature resistance and impact resistance, its hardness is lower than that of metal materials. When the pot body assembly 25 is pulled out, the coating on the bottom of the pot body 251 will not be scratched, which is conducive to improving the quality and reliability of the cooking equipment.
[0035] It should be noted that the isolation bracket 3 is arranged above the base plate 24, and its isolation can be directly fixed to the base plate 24 by welding or hot melting, or fixed to the base plate 24 by locking parts such as countersunk screws, or by other structures that can fix the isolation bracket 3 and the base plate 24 together.
[0036] In a possible implementation, a locking hole matching the countersunk screw is provided on the isolation bracket 3, and a through hole is provided through the bottom plate 24. The countersunk screw is inserted into the locking hole and the through hole corresponding thereto, and the countersunk screw, the locking hole and the through hole are locked, so as to fix the isolation bracket 3 and the bottom plate 24 together. The head of the countersunk screw is flush with or lower than the surface of the isolation bracket 3, so that the surface of the isolation bracket 3 remains flat, and the connection stability between the isolation bracket 3 and the bottom plate 24 can be ensured.
[0037] In another possible implementation, the isolation bracket 3 and the base plate 24 can also be directly fixed together by mutual snap-fitting. For example, a card slot is provided on the base plate 24, and the isolation bracket 3 can be configured as a card block that can be inserted into the corresponding card slot. The isolation bracket 3 and the base plate 24 can be fixed together by inserting the card block into the card slot without the aid of a locking member. This can firmly fix the isolation bracket 3 on the base plate 24 while simplifying the connection structure between the isolation bracket 3 and the base plate 24 and reducing the number of parts, thereby simplifying the assembly process of the cooking equipment and shortening the time required for assembly.
[0038] There are at least two isolation brackets 3, and at least two isolation brackets 3 are respectively arranged on the left and right sides of the bottom plate 24 to ensure the stability of the pot body assembly 25 when placed on the isolation brackets 3, to avoid the possibility of the pot body assembly 25 tilting during the cooking process, and thus to improve the overall safety of the cooking device. In other embodiments, there can also be one isolation bracket 3, which is arranged in the middle of the bottom plate 24, to ensure the stability of the pot body assembly 25 placed on the isolation brackets 3, to reduce the number of isolation brackets 3, and to further simplify the assembly process of the cooking device.
[0039] It should be noted that, combined with Figure 3 The isolation bracket 3 extends along the moving direction of the pot body assembly 25. When the pot body assembly 25 needs to be placed in the lower shell 2, the isolation bracket 3 can guide the pot body 251, which is beneficial to the installation and pulling of the pot body assembly 25.
[0040] In one possible implementation, a row of isolation components are respectively provided on the left and right sides of the bottom plate 24, and each row of isolation components includes a plurality of isolation brackets 3. The plurality of isolation brackets 3 are distributed along the moving direction of the pot body assembly 25 and extend along the moving direction of the pot body assembly 25, which can improve the overall safety of the cooking equipment and at the same time guide the pulling and pulling of the pot body assembly 25.
[0041] In addition, the side of the bottom plate 24 close to the opening is inclined, which is convenient for guiding when the pot body assembly 25 is placed in the lower shell 2, and facilitates the pulling out of the pot body assembly 25; at the same time, a guiding slope 31 is provided on the side of the isolation bracket 3 close to the opening, which further facilitates the pulling out of the pot body assembly 25 and helps to place the pot body assembly 25 in the lower shell 2.
[0042] Embodiment 2:
[0043] The difference between this embodiment and embodiment 1 is that: Figure 4 and Figure 5As shown, the isolation bracket 3 extends downward to be provided with a connecting piece 4, which is located between the bottom plate 24 and the bottom shell 22 and is connected to the bottom shell 22; this prevents the pot body assembly 25 from directly contacting the bottom plate 24 when being pulled out, causing scratches on the bottom of the pot body assembly 25, and also reduces the heat transfer from the pot body assembly 25 to the bottom shell 22, thereby avoiding excessive temperature at the bottom shell 22 and causing thermal deformation.
[0044] It should be noted that, in order to reduce the overall weight of the cooking device, the bottom shell 22 is mostly made of plastic. Although the plastic bottom shell 22 has certain strength and heat resistance, it will still be thermally deformed under continuous high temperature. By arranging the connector 4 between the bottom plate 24 and the bottom shell 22, and the bottom of the pot body assembly 25 is in direct contact with the isolation bracket 3, the heat in the pot body assembly 25 is transferred to the isolation bracket 3 and the connector 4 during the cooking process. Since the plastic part has poor thermal conductivity compared to metal materials, it can reduce the heat transfer to the bottom shell 22, and prevent the bottom shell 22 from melting due to excessive temperature.
[0045] A positioning rod 5 is provided at the bottom of the connector 4, and a connecting block 6 is provided on the bottom shell 22. A positioning hole for the positioning rod 5 to extend is provided on the connecting block 6, which is used to connect the connector 4 to the bottom shell 22. Support blocks 7 are distributed circumferentially on the connecting block 6 to enhance the strength of the connecting block 6 and ensure the connection stability between the positioning rod 5 and the connecting block 6. It should be noted that the bottom shell 22 of a general air fryer is relatively thin, which is not convenient for setting the positioning hole, or the positioning hole set on the relatively thin bottom shell 22 is not strong enough and is easy to loosen after being connected with the positioning rod 5. The positioning hole is set on the connecting block 6 located on the bottom shell 22, which is conducive to ensuring the strength of the positioning hole and the reliability between the positioning rod 5 and the connecting block 6.
[0046] In this embodiment, a connection hole 241 is provided on the bottom plate 24, and the top surface of the isolation bracket 3 extends upward through the connection hole 241 and contacts the bottom of the pot body 251. During installation, after the connector 4 is fixed to the bottom shell 22, the bottom plate 24 is installed so that the isolation bracket 3 passes through the connection hole 241 of the bottom plate 24. On the one hand, it can prevent the pot body assembly 25 from contacting the bottom plate 24, and on the other hand, it can play a role in positioning the bottom plate 24, which is convenient for the subsequent connection and fixation of the bottom plate 24 and the bottom shell 22.
[0047] In one possible implementation, at least two isolation brackets 3 are provided, and at least two isolation brackets 3 are distributed along the moving direction of the pot body assembly 25, and the connecting parts 4 corresponding to at least two isolation brackets 3 are integrally provided, which can reduce the number of parts required between the connecting parts 4 and the bottom shell 22, thereby helping to simplify the assembly process of the cooking equipment and shorten the time required for assembly.
[0048] In this embodiment, a row of isolation components are respectively arranged on the left and right sides of the bottom plate 24, and each row of isolation components includes a plurality of isolation brackets 3. The plurality of isolation brackets 3 are distributed along the moving direction of the pot body assembly 25 and extend downward to form a connecting piece 4, which can ensure the stability of the pot body assembly 25 placed on the isolation bracket 3 and at the same time play a guiding role in the pulling and drawing of the pot body assembly 25.
[0049] Embodiment 3:
[0050] The difference between this embodiment and the above embodiment is that: Figure 6 As shown, an air inlet 8 is provided at the bottom of the bottom shell 22, a gap is provided between the bottom shell 22 and the bottom plate 24 to form a first space 81, a gap is provided between the outer shell 21 and the lining 23 to form a second space 82 connected to the first space 81, and an air outlet connected to the outside air is provided on the outer shell 21.
[0051] The cold air from the outside enters the first space 81 through the air inlet 8, passes through the second space 82, and is finally discharged from the air outlet to achieve a complete cold air circulation; during the cold air circulation process, it can take away the heat from the bottom shell 22, reduce the temperature of the bottom shell 22, and improve the overall safety.
[0052] It should be noted that, in order to reduce the overall weight of the cooking device, the bottom shell 22 is made of plastic. The bottom air suction structure is adopted, so that the heat at the bottom shell 22 can be taken away from the air outlet through the first space 81 and the second space 82, thereby preventing the temperature at the bottom shell 22 from being too high and causing the plastic bottom shell 22 to melt, and also solving the problem of the metal material bottom plate 24 and the plastic bottom shell 22 directly contacting each other and causing the temperature at the connection to be too high.
[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
