The inner viewing panel is adapted to fit tightly against the air duct plate and the upper core through the sealing ring.
[0003] However, the air fryer mentioned above has the following drawbacks: In order to prevent the circulating heat flow in the cooking cavity from flowing out, the air fryer is equipped with a sealing ring, but it lacks a position detection structure. If the air fryer does not close properly when it starts working, heat leakage is still likely to occur, which urgently needs to be improved. Utility Model Content
[0004] The purpose of this invention is to provide an air fryer with a safe start-up function, which ensures that the air fryer will only start working when the lid is fully closed on the fryer body, and at the same time reduces heat loss during operation.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an air fryer with a safe start function, comprising an air fryer body and a lid body formed on the air fryer body, wherein the bottom of the lid body is provided with a sealing element that seals with the air fryer body, and a floating lifting structure is provided between the lid body and the sealing element, wherein the sealing element is floatingly connected to the bottom of the lid body through the floating lifting structure, so that the sealing element relative to the lid body can switch between a sealing position and a releasing position.
[0006] The pot lid body is equipped with a trigger switch assembly. When the sealing element is in the sealing position, the sealing element is pressed into contact with the trigger switch assembly.
[0007] By adopting the above technical solution, when the lid body is separated from the fryer body, the seal is in a released state separated from the lid body. At this time, the trigger switch assembly is in the off state, and the air fryer is not powered on. When the lid body is placed on the fryer body and closed in place, the seal is pushed up by the fryer body and pressed against the lid body, so that the seal can make contact with the trigger switch assembly, realizing the power supply of the air fryer. At the same time, the seal is pressed and sealed between the lid body and the fryer body, which can reduce the heat leakage of the air fryer during operation. It has the purpose of realizing that the air fryer will only enter the working state when the lid body is closed on the fryer body, and also has the effect of reducing the heat loss of the air fryer during operation.
[0008] A further feature of this invention is that the floating lifting structure includes a floating connector and a lifting trajectory groove. The floating connector is fixedly connected to the sealing element. The lifting trajectory groove is opened on the pot lid body along the lifting and floating direction of the sealing element. The side wall of the floating connector is provided with a limiting buckle corresponding to the lifting trajectory groove. The limiting buckle constrains and slides within the lifting trajectory groove.
[0009] By adopting the above technical solution, the limiting buckle and the lifting track groove are constrained so that the limiting buckle can only slide up and down within the lifting track groove, thereby allowing the sealing element to float relative to the pot lid body within the lifting stroke of the lifting track groove through the floating connector.
[0010] A further feature of this invention is that: a guide sleeve is provided at the bottom of the pot lid body, the floating connector is movably inserted into the guide sleeve, the lifting trajectory groove is opened on the side wall of the guide sleeve, and the lifting trajectory groove communicates with the inner cavity of the guide sleeve.
[0011] By adopting the above technical solution, the inner cavity of the guide sleeve can limit the lifting and sliding direction of the floating connector, thereby improving the consistency of the lifting and sliding direction of the floating connector relative to the main body of the pot lid.
[0012] A further feature of this invention is that an elastic element is provided between the floating connector and the pot lid body, and the elastic element has a tendency to push the floating connector and the sealing element away from the pot lid body.
[0013] By adopting the above technical solution, when the lid body is closed onto the fryer body, the fryer body pushes the sealing element upward to press against the lid body. At the same time, the sealing element pushes the floating connector upward relative to the guide sleeve, causing the limiting buckle to move upward at the position of the lifting track groove. The elastic element is compressed, and the elastic element gives the sealing element a downward pressing force, further reducing the heat loss of the air fryer during operation. When the lid body is removed from the fryer body, the elastic element releases the accumulated elastic potential energy. Under the guidance of the limiting buckle and the lifting track groove, it pushes the floating connector and the sealing element away from the lid body, realizing the automatic reset of the sealing element.
[0014] A further feature of this invention is that a guide rail structure is provided between the pot lid body and the sealing element, and the sealing element slides and engages with the pot lid body through the guide rail structure.
[0015] By adopting the above technical solution and adding the guide rail structure, the directional consistency of the sealing element's lifting and sliding relative to the main body of the pot lid is further improved.
[0016] A further feature of this invention is that: the pot lid body has a first flange extending around its perimeter toward the fryer body; the guide rail structure includes several guide ribs and guide grooves; the several guide ribs extend into the inner wall of the first flange; the guide grooves are formed in the side wall of the sealing element; and the guide ribs and the guide grooves guide and slide together.
[0017] A further feature of this invention is that the sealing element extends to one side of the fryer body with a second flange, and the outer wall of the second flange is sealed and fitted to the inner wall of the first flange.
[0018] By adopting the above technical solution, when the sealing element moves up and down relative to the pot lid body, the outer side of the sealing element can always maintain a seal with the first flange on the outer side of the pot lid body through the second flange, which can effectively improve the airtightness and heat preservation ability between the sealing element and the pot lid body.
[0019] A further feature of this invention is that the trigger switch assembly includes a micro switch and a push rod, the push rod being slidably disposed on the pot lid body, and when the sealing member is in the sealing position, the sealing member pushes the push rod to press and engage with the micro switch.
[0020] By adopting the above technical solution, when the pot lid body is closed on the fryer body, the fryer body pushes the sealing element upward to press against the pot lid body, and at the same time pushes the top rod upward. The top of the top rod presses the micro switch, thereby realizing the detection and judgment that the pot lid body is closed.
[0021] A further feature of this invention is that the pot lid body includes a lid assembly and a reflector assembly. The lid assembly has an installation space inside, and the micro switch is installed in the installation space. The reflector assembly has a through hole, and the push rod is movably inserted into the through hole. The push rod includes a driving end and an actuating end. The driving end abuts against the sealing element, and the actuating end presses against the switch contact of the micro switch.
[0022] By adopting the above technical solution and placing the micro switch within the installation space, the heat inside the reflector assembly can be effectively isolated, preventing the micro switch from being damaged due to overheating.
[0023] A further feature of this invention is that the pot lid body includes a hot air generating module, and an air passage hole is provided in the middle of the sealing member, through which the hot air output by the hot air generating module is blown into the inner cavity of the fryer body.
[0024] In summary, this utility model has the following beneficial effects:
[0025] The air fryer employs a floating connection between the sealing element and the bottom of the lid body via a floating lifting structure. A trigger switch assembly is also installed within the lid body. When the lid body is separated from the fryer body, the sealing element is in a released state, and the trigger switch assembly is off, preventing the air fryer from being powered on. When the lid body is placed on the fryer body and fully closed, the sealing element is pushed against and pressed against the lid body by the fryer body, allowing it to contact the trigger switch assembly and powering the air fryer on. Simultaneously, the sealing element is compressed and sealed between the lid body and the fryer body, reducing heat loss during operation. This design ensures the air fryer only starts operating when the lid body is fully closed on the fryer body, effectively minimizing heat loss during operation. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings.
[0035] An air fryer with a safe start function, such as Figure 1-7 As shown, the device includes a fryer body 1 and a lid body 2 formed on the fryer body 1. The bottom of the lid body 2 is provided with a sealing element 3 that seals with the fryer body 1. A floating lifting structure is provided between the lid body 2 and the sealing element 3. The sealing element 3 is floatingly connected to the bottom of the lid body 2 through the floating lifting structure, so that the sealing element 3 can switch between a sealing position and a releasing position relative to the lid body 2. The lid body 2 is provided with a trigger switch assembly 4. When the sealing element 3 is in the sealing position, the sealing element 3 and the trigger switch assembly 4 are pressed into contact.
[0036] like Figure 2-6As shown, the floating lifting structure includes a floating connector 5 and a lifting trajectory groove 2131. The floating connector 5 is fixedly connected to the sealing member 3, and the sealing member 3 and the floating connector 5 are fixedly connected by fasteners, such as bolts. The lifting trajectory groove 2131 is opened on the pot lid body 2 along the lifting and floating direction of the sealing member 3. The side wall of the floating connector 5 is provided with a limiting buckle 51 corresponding to the lifting trajectory groove 2131. The limiting buckle 51 constrains and slides within the lifting trajectory groove 2131. The constraint effect of the lifting track groove 2131 on the sealing element 1 ensures that the limiting buckle 51 can only slide up and down within the lifting track groove 2131, thereby allowing the sealing element 3 to float relative to the pot lid body 2 within the lifting stroke of the lifting track groove 2131 via the floating connector 5. A guide sleeve 213 is provided at the bottom of the pot lid body 2, and the floating connector 5 is movably inserted into the guide sleeve 213. The lifting track groove 2131 is formed on the side wall of the guide sleeve 213, and the lifting track groove 2131 communicates with the inner cavity of the guide sleeve 213. The inner cavity of the guide sleeve 213 can limit the lifting and sliding direction of the floating connector 5, improving the consistency of the lifting and sliding direction of the floating connector 5 relative to the lid body 2; an elastic element 6 is provided between the floating connector 5 and the lid body 2, and the elastic element 6 has a tendency to push the floating connector 5 and the sealing element 3 away from the lid body 2. When the lid body 2 is closed on the fryer body 1, the fryer body 1 pushes the sealing element 3 upward to press against the lid body 2, and at the same time the sealing element 3 pushes the floating connector 5. As the guide sleeve 213 moves upward, the limiting buckle 51 moves upward at the position of the lifting track groove 2131, the elastic element 6 is compressed, and the elastic element 6 gives the sealing element 3 a downward pressing force, further reducing the heat loss of the air fryer during operation; when the lid body 2 is removed from the air fryer body 1, the elastic element 6 releases the accumulated elastic potential energy, and under the guidance of the limiting buckle 51 and the lifting track groove 2131, pushes the floating connector 5 and the sealing element 3 away from the lid body 2, realizing the automatic reset of the sealing element 3.
[0037] like Figure 2-4As shown, a guide rail structure is provided between the pot lid body 2 and the sealing element 3. The sealing element 3 slides and cooperates with the pot lid body 2 through the guide rail structure. The addition of the guide rail structure further improves the consistency of the sliding direction of the sealing element 3 relative to the pot lid body 2. The pot lid body 2 has a first flange 214 extending from all four sides toward the fryer body 1. The guide rail structure includes several guide ribs 2141 and guide grooves 31. Several guide ribs 2141 extend into the inner wall of the first flange 214, and guide grooves 31 are formed on the side wall of the sealing element 3. The guide ribs 2141 and guide grooves 31 slide and cooperate with each other. In this embodiment, the guide grooves 31 and 31 are... A plurality of guide grooves 31 are formed around the outer edge of the seal 3, and the innermost side of the multiple guide grooves 31 is located on the outer side of the pot body of the fryer body 1 in the height direction to ensure the sealing performance of the seal 3; the seal 3 extends a second flange 32 on the side of the fryer body 1, and the outer wall of the second flange 32 is sealed and fitted with the inner wall of the first flange 214, so that when the seal 3 slides up and down relative to the pot lid body 2, the outer side of the seal 3 can always be sealed with the first flange 214 on the outer side of the pot lid body 2 through the second flange 32, which can effectively improve the airtightness and heat preservation ability between the seal 3 and the pot lid body 2.
[0038] like Figure 2-7 As shown, the trigger switch assembly 4 includes a micro switch 41 and a push rod 42. The push rod 42 is slidably mounted on the lid body 2. The sealing member 3, in the sealed position, pushes the push rod 42 to press against the micro switch 41. When the lid body 2 is closed on the fryer body 1, the fryer body 1 pushes the sealing member 3 upward to press against the lid body 2, and at the same time pushes the push rod 42 upward. The top of the push rod 42 presses against the micro switch 41, thereby realizing the detection and judgment that the lid body 2 is closed. The lid body 2 includes a lid assembly 21 and a reflector assembly 22. The lid assembly 21 has an installation space 210 inside, and the micro switch 41 is installed in the installation space 210. The reflector assembly 22 has a through hole 221, and the push rod 42 is movably inserted into the through hole 221. The push rod 42 includes a drive end 421 and an actuation end 422. The drive end 421 abuts against the seal 3, and the actuation end 422 presses against the switch contact 411 of the micro switch 41, placing the micro switch 41 in the installation space 210. This effectively isolates the heat in the reflector assembly 22 and prevents the micro switch 41 from overheating and being damaged. The pot lid body 2 includes a hot air generating module 23. A vent 33 is opened in the middle of the seal 3. The hot air output by the hot air generating module 23 is blown into the inner cavity of the fryer body 1 through the vent 33. In this embodiment, the lid assembly 21 includes an upper cover 211 and a lower cover 212. The installation space 210 is formed between the upper cover 211 and the lower cover 212. The micro switch 41 is installed on the lower cover 212 and located in the installation space 210.
[0039] The basic working principle of this utility model is as follows: A sealing element 3 is floatingly connected to the bottom of the lid body 2 through a floating lifting structure. At the same time, a trigger switch assembly 4 is set in the lid body 2. When the lid body 2 is separated from the fryer body 1, the sealing element 3 is in a released state separated from the lid body 2. At this time, the trigger switch assembly 4 is in an open state, and the air fryer is not powered on. When the lid body 2 is placed on the fryer body 1 and closed in place, the sealing element 3 is pushed up by the fryer body 1 and pressed against the lid body 2, so that the sealing element 3 can press and contact with the trigger switch assembly 4, realizing the power supply of the air fryer. At the same time, the sealing element 3 is pressed and sealed between the lid body 2 and the fryer body 1, which can reduce the heat leakage when the air fryer is working. It has the purpose of realizing that the air fryer will only enter the working state when the lid body is closed on the fryer body, and also has the effect of reducing the heat loss when the air fryer is working.
[0040] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
