[0001] This utility model relates to the field of air fryer technology, and in particular to an air fryer that prevents accidental opening. Background Technology

[0002] A Chinese patent with publication number CN214104196U discloses an air fryer, including a main body, an open button, a display screen, a frying basket, a motor, a threaded rod, a frying net, a heating element, a fan, a main control chip, and a wireless connection module. The main body is provided with the open button, and the display screen is located above the open button. The frying basket is located on the upper part of the base, and the motor is located inside the frying basket. The threaded rod is located at one end of the motor. The frying net is located on the upper part of the frying basket, and the heating element is located on the upper part of the frying net. The fan is located on the upper part of the heating element.

[0003] However, the air fryer mentioned above has the following drawbacks: the fan and heating element of the air fryer are fixedly installed inside the main body, which reduces the height space of the frying basket. In addition, the air fryer is started by pressing the open button, which is prone to accidental opening and is not safe to use. It urgently needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide an air fryer that prevents accidental opening, which increases the cooking space of the air fryer and effectively prevents the hot air blower head from being accidentally opened.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an air fryer that prevents accidental opening, including a hot air blower head and a cooking body with a receiving cavity, wherein the hot air blower head is raised and lowered in the receiving cavity, and a locking structure is provided between the hot air blower head and the cooking body. The hot air blower head has an electronic control board and an air duct. The air duct is equipped with a hot air generating device electrically connected to the electronic control board. The side wall of the hot air blower head has an air inlet connected to the air duct, and the bottom of the hot air blower head has an air outlet connected to the air duct. The hot air blower head is equipped with a micro switch electrically connected to the electronic control board. The top of the cooking body is equipped with a trigger part corresponding to the micro switch. When the hot air blower head extends upward into the receiving cavity, and the hot air blower head is locked and positioned with the cooking body through the locking structure, the trigger part and the micro switch are pressed together.

[0006] By adopting the above technical solution, when the hot air blower head is retracted into the receiving cavity, the micro switch is in the closed state. At this time, the hot air blower head will not work even if connected to a power source. When in use, the hot air blower head needs to be lifted from the receiving cavity to a predetermined height, so that the hot air blower head is locked and fixed to the cooking body by the locking structure, keeping the hot and cold air blower heads in the extended use state relative to the cooking body. At this time, the trigger part presses the micro switch to switch to the open state. By connecting the power source, the electronic control board controls the hot air generator to draw airflow into the air duct through the air inlet, and under the drive of the hot air generator, hot air is generated. The hot air then passes through the hot air blower... The air vent at the bottom of the air fryer blows air onto the cooking body to heat the food. When heating food, the hot air blower head is extended relative to the cooking body, greatly increasing the effective cooking space of the air fryer. In addition, by setting a micro switch on the hot air blower head, power can only be turned on when the hot air blower head is extended relative to the cooking body and the trigger part is pressed. This can effectively prevent the air fryer from being accidentally opened due to operator error. Especially for families with children, this greatly improves the safety of operation and has the effects of increasing the cooking space of the air fryer and effectively preventing the hot air blower head from being accidentally opened.

[0007] A further feature of this invention is that the top of the cooking body extends radially inward to form an annular countertop, the upper opening of the receiving cavity penetrates the annular countertop, and the triggering part is integrally formed on the bottom of the annular countertop.

[0008] By adopting the above technical solution, the trigger part is set at the bottom of the annular platform, which improves the contact stability between the trigger part and the micro switch.

[0009] A further feature of this invention is that the annular platform extends toward the side wall of the receiving cavity to form a positioning part, and the side wall of the hot air blower head is provided with an anti-rotation surface corresponding to the positioning part, and the hot air blower head engages with the positioning part through the anti-rotation surface to prevent rotation.

[0010] By adopting the above technical solution, the hot air blower head can only move vertically relative to the cooking body, and cannot rotate horizontally relative to the cooking body. This allows the hot air blower head to be effectively locked to the cooking body through a locking structure when it is raised, effectively avoiding the situation where the locking fails due to positional deviation.

[0011] A further feature of this invention is that the trigger portion extends at least partially to the bottom of the positioning portion, and the bottom surface of the trigger portion is a plane.

[0012] By adopting the above technical solution, it is beneficial to increase the effective contact area between the bottom plane of the trigger part and the micro switch.

[0013] A further feature of this invention is that the hot air blower head includes a blower head housing and a panel assembly mounted on the top of the blower head housing. The panel assembly includes a support portion located above the anti-rotation surface and extending outward. The positioning portion and the support portion mutually stop and support each other.

[0014] By adopting the above technical solution, when the hot air blower head is lowered into the receiving cavity and in a retracted state, the support part of the panel assembly can effectively support the positioning part of the cooking body, preventing the hot air blower head from sinking too much and detaching from the cooking body.

[0015] A further feature of this invention is that the hot air blower head includes a blower head base, the bottom of the blower head housing extends outward to form a lower flange, the blower head base includes a base body and an upper flange extending upward along the edge of the base body, the bottom of the blower head housing is fixedly connected to the upper flange through the lower flange, and an installation cavity for accommodating the micro switch is formed between the upper flange, the lower flange and the base body, and an avoidance hole is provided on the lower flange corresponding to the switch button of the micro switch.

[0016] By adopting the above technical solution, the micro switch is installed on the outer side of the bottom of the hot air blower head, thereby ensuring that the switch button of the micro switch can be effectively pressed with the trigger part.

[0017] A further feature of this invention is that the positioning part is formed on the bottom inner wall of the annular platform, and the positioning part has a plurality of protrusions on the side wall facing the receiving cavity, and the side wall of the hot air blower head slides in cooperation with the protrusions in the vertical direction.

[0018] By adopting the above technical solution, the protrusion can reduce the contact area between the side wall of the hot air blower head and the positioning part, thereby improving the smoothness of the hot air blower head's lifting and sliding.

[0019] A further feature of this invention is that adjacent protrusions are spaced apart, and the protrusions extend vertically along the lifting direction of the hot air blower head.

[0020] A further feature of this invention is that the cooking body includes a main shell, a fixed ring fixedly connected to the upper part of the main shell, and a rotating ring coaxially and rotatably connected to the fixed ring. The locking structure includes a locking block and a locking engagement part. The locking block protrudes from the side wall of the hot air blower head, and the locking engagement part is located on the rotating ring. An elastic reset member is connected between the rotating ring and the fixed ring. When the hot air blower head rises relative to the cooking body, causing the locking block to pass the corresponding locking engagement part, the elastic reset member drives the rotating ring to engage the locking engagement part with the locking block for locking.

[0021] By adopting the above technical solution, the hot air blower head is lifted vertically upward from the receiving cavity of the cooking body. The hot air blower head drives the locking block to rise synchronously. The locking block pushes the rotating ring to rotate in the unlocking direction, causing the elastic reset component to accumulate elastic potential energy. When the locking block passes the locking engagement part, the elastic reset button releases the elastic potential energy and pulls the rotating ring to rotate in the locking direction, so that the locking block and the locking engagement part lock each other, thereby allowing the hot air blower head to remain in the working state of extending out of the receiving cavity. This utility model ensures that the locking process is completed automatically through the design of the elastic reset component, reducing manual intervention. At the same time, the self-locking structure can realize the axial limit of the hot air blower head relative to the rotating ring, preventing the hot air blower head from accidentally sinking during use.

[0022] A further feature of this invention is that the side wall of the locking block is provided with a guide slope, and the locking block is guided and engaged with the locking engagement part through the guide slope.

[0023] By adopting the above technical solution, the addition of the guide ramp facilitates the locking block's upward lifting, allowing it to smoothly rotate the rotating ring in the unlocking direction.

[0024] In summary, this utility model has the following beneficial effects: The hot air blower head is positioned and raised within the housing of the cooking unit, with a locking mechanism between the head and the unit. The blower head is equipped with a microswitch, and the top of the cooking unit has a trigger. When the blower head is retracted into the housing, the microswitch is in the off state, meaning it will not operate even when connected to power. To use, the blower head must be lifted from the housing to a predetermined height, locking it to the cooking unit using the locking mechanism, keeping the blower head extended relative to the cooking unit. Pressing the trigger activates the microswitch, turning it on. Power is then supplied, and the control board directs the hot air generator to draw airflow through the air inlet. The air duct generates hot air, which is then blown onto the cooking body through the air outlet at the bottom of the hot air blower head to heat the food. When heating food, the hot air blower head is extended relative to the cooking body, greatly increasing the effective cooking space of the air fryer. In addition, by setting a micro switch on the hot air blower head, power can only be turned on when the hot air blower head is extended relative to the cooking body and the trigger part is pressed. This can effectively prevent the air fryer from being accidentally opened due to operator error. Especially for families with children, this greatly improves the safety of operation and has the effects of increasing the cooking space of the air fryer and effectively preventing the hot air blower head from being accidentally opened.

[0035] The present invention will be further described below with reference to the accompanying drawings.

[0036] An air fryer designed to prevent accidental opening, such as Figures 1-7As shown, the cooking body 5 includes a hot air blower head 1 and a cooking body 5 with a receiving cavity 51. The hot air blower head 1 is raised and lowered in the receiving cavity 51, and a locking structure is provided between the hot air blower head 1 and the cooking body 5. The hot air blower head 1 has an electronic control board 11 and an air duct 12. A hot air generating device 13 electrically connected to the electronic control board 11 is provided in the air duct 12. An air inlet 21 connected to the air duct 12 is provided on the side wall of the hot air blower head 1, and an air outlet 41 connected to the air duct 12 is provided at the bottom of the hot air blower head 1. The hot air blower head 1 is provided with a micro switch 14 electrically connected to the electronic control board 11. A trigger part 62 is provided on the top of the cooking body 5 corresponding to the micro switch 14. When the hot air blower head 1 extends upward out of the receiving cavity 51, and the hot air blower head 1 is locked and positioned with the cooking body 5 through the locking structure, the trigger part 62 and the micro switch 14 are pressed together.

[0037] like Figures 1-6 As shown, the top of the cooking body 5 extends radially inward to form an annular countertop 61. The upper opening of the receiving cavity 51 penetrates the annular countertop 61, and the trigger part 62 is integrally formed at the bottom of the annular countertop 61. Setting the trigger part 62 at the bottom of the annular countertop 61 improves the contact stability between the trigger part 62 and the micro switch 14. The annular countertop 61 extends toward the side wall of the receiving cavity 51 to form a positioning part 63. The side wall of the hot air blower head 1 is provided with an anti-rotation surface 22 corresponding to the positioning part 63. The hot air blower head 1 is anti-rotated by engaging with the positioning part 63 through the anti-rotation surface 22, so that the hot air blower head 1 can only be raised and lowered vertically relative to the cooking body 5, and cannot rotate horizontally relative to the cooking body 5. This allows the hot air blower head 1 to be effectively locked with the cooking body 5 through the locking structure when it is raised, effectively avoiding the situation where the locking fails due to positional displacement. The trigger part 62 extends at least partially to the bottom of the positioning part 63, and the bottom surface of the trigger part 62 is set as a plane, which helps to increase the effective contact area between the bottom plane of the trigger part 62 and the micro switch 14.

[0038] like Figures 2-9As shown, the hot air blower head 1 includes a head housing 2 and a panel assembly 3 mounted on the top of the head housing 2. The panel assembly 3 includes a support portion 31 extending outward above the anti-rotation surface 22. The positioning portion 63 and the support portion 31 mutually stop and support each other. When the hot air blower head 1 is lowered into the receiving cavity 51 and is in a retracted state, the support portion 31 of the panel assembly 3 can effectively support the positioning portion 63 of the cooking body 5, preventing the hot air blower head 1 from sinking excessively and detaching from the cooking body 5. The hot air blower head 1 includes a head base 4. The bottom of the head housing 2 extends outward to form a lower flange 23. The head base 4 includes a base body and an upper flange 42 extending upward along the edge of the base body. The bottom of the head housing 2 is fixedly connected to the upper flange 42 through the lower flange 23. The upper flange 42 and the lower flange 23 are... A mounting cavity 10 is formed between the base body and the base body to accommodate the micro switch 14. The lower flange 23 has a clearance hole 231 corresponding to the switch button 141 of the micro switch 14, so that the micro switch 14 is installed on the outer side of the bottom of the hot air blower head 1, thereby ensuring that the switch button 141 of the micro switch 14 can effectively press the trigger part 62. The positioning part 63 is formed on the bottom inner wall of the annular platform 61, and the positioning part 63 has a number of protrusions 631 on the side wall facing the receiving cavity 51. The side wall of the hot air blower head 1 slides with the protrusions 631 in the vertical direction. The protrusions 631 can reduce the contact area between the side wall of the hot air blower head 1 and the positioning part 63, thereby improving the smoothness of the lifting and sliding of the hot air blower head 1. Adjacent protrusions 631 are spaced apart, and the protrusions 631 extend vertically along the lifting direction of the hot air blower head 1.

[0039] like Figures 2-8As shown, the cooking body 5 includes a main shell 6, a fixed ring 7 fixedly connected to the upper part of the main shell 6, and a rotating ring 8 coaxially and rotatably connected to the fixed ring 7. The locking structure includes a locking block 421 and a locking engagement part 81. The locking block 421 protrudes from the side wall of the hot air blower head 1, and the locking engagement part 81 is located on the rotating ring 8. An elastic reset member 82 is connected between the rotating ring 8 and the fixed ring 7. When the hot air blower head 1 rises relative to the cooking body 5, causing the locking block 421 to pass the corresponding locking engagement part 81, the elastic reset member 82 drives the rotating ring 8 to engage with the locking engagement part 81 and lock the locking block 421, lifting the hot air blower head 1 vertically upward from the receiving cavity 51 of the cooking body 5. The hot air blower head 1 drives the locking block 421 to rise synchronously upward, and the locking block 421 pushes the rotating ring 8 to rotate in the unlocking direction, causing the elastic reset member 82 to accumulate elastic potential energy. After 421 passes the locking engagement part 81, the elastic reset key releases its elastic potential energy and pulls the rotating ring 8 to rotate in the locking direction, so that the locking block 421 and the locking engagement part 81 lock together, thereby allowing the hot air blower head 1 to remain in the extended position of the receiving cavity 51. This utility model ensures that the locking process is completed automatically through the design of the elastic reset part 82, reducing manual intervention. At the same time, the self-locking structure can realize the axial limit of the hot air blower head 1 relative to the rotating ring 8, preventing the hot air blower head 1 from accidentally sinking during use. The side wall of the locking block 421 is inclined with a guide slope 4211. The locking block 421 is guided and engaged with the locking engagement part 81 through the guide slope 4211. The addition of the guide slope 4211 is beneficial to the locking block 421 being able to push the rotating ring 8 to rotate smoothly in the unlocking direction when the locking block 421 is lifted upward.

[0040] The basic working principle of this utility model is as follows: The hot air blower head 1 is raised and lowered and placed in the receiving cavity 51 of the cooking body 5, and a locking structure is set between the hot air blower head 1 and the cooking body 5. In addition, the hot air blower head 1 is equipped with a micro switch 14, and the top of the cooking body 5 is equipped with a trigger part 62. When the hot air blower head 1 is stored in the receiving cavity 51, the micro switch 14 is in the closed state. At this time, the hot air blower head 1 will not work even if it is connected to the power supply. When in use, the hot air blower head 1 needs to be lifted from the receiving cavity 51 to a predetermined height so that the hot air blower head 1 is locked and fixed to the cooking body 5 by the locking structure, so that the hot and cold air blower head 1 is kept in the extended use state relative to the cooking body 5. At this time, the trigger part 62 presses the micro switch 14 to switch it to the open state. By connecting the power supply, the electronic control board 11 controls the hot air generating device. Airflow is drawn into the air duct 12 through the air inlet 21 and hot air is generated under the drive of the hot air generator 13. The hot air is then blown onto the cooking body 5 through the air outlet 41 at the bottom of the hot air blower head 1 to heat the food. When heating food, the hot air blower head 1 is in an extended state relative to the cooking body 5, which greatly improves the effective cooking space of the air fryer. In addition, by setting the micro switch 14 on the hot air blower head 1, the power can only be turned on when the hot air blower head 1 is in an extended state relative to the cooking body 5 and the trigger part 62 presses the micro switch 14. This can effectively prevent the air fryer from being accidentally opened due to operator misoperation. Especially for families with children, this greatly improves the safety of operation and has the effects of increasing the cooking space of the air fryer and effectively preventing the hot air blower head from being accidentally opened.

[0041] 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.
