Description

Technical Field

[0001] This utility model relates to the field of air fryers, specifically a safety structure for the head of an air fryer. Background Technology

[0002] Current air fryer structures mainly consist of a pot body, with a detachable main unit on the upper side of the pot body. The main unit contains a motor, and the motor's output shaft is connected to a circulating fan blade. Below the circulating fan blade is a heating element. During use, the main unit can be completely detached from the pot body to open or close the pot opening. However, if the main unit is used improperly or subjected to external force, it is prone to displacement or loosening. Alternatively, if the user suddenly lifts the main unit during use, it can cause hot air leakage, posing a safety hazard. Users can only manually turn off the main unit's operating circuit before each disassembly.

[0003] Therefore, some air fryers use a micro switch. When the micro switch is in contact, a trigger signal is sent to the main control board through the signal transmitter, thereby turning on the working circuit of the air fryer. Conversely, the working circuit of the air fryer is turned off. However, the main body leaving the pot and the circuit being turned off occur simultaneously, so there is still a risk of hot air leakage. Therefore, the applicant has improved and perfected the air fryer to solve the above problems and provide consumers with options for use. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned existing problems and provide a simple and reasonable safety structure for the air fryer head.

[0005] An air fryer head safety structure includes a pot body, a detachable main body on the upper side of the pot body, a hot air assembly for supplying hot air into the inner cavity of the pot body, a sliding handle on the top surface of the main body, an elastic retractable component connected to the handle, the handle being able to elastically return to a retracted position from the pulled-up position via the elastic retractable component, and a switching element that dynamically engages with the handle within the main body. When the handle is in the pulled-up or retracted position, the circuit of the main body is disconnected or connected by the separation or contact between the handle and the switching element.

[0006] The objective of this utility model can also be achieved by the following technical measures:

[0007] As a more specific embodiment, the two ends of the handle of the machine head extend downward with guide feet, the main body includes a shell, the shell has a guide through hole that forms a linear sliding fit with the guide feet, and the switching element forms a dynamic contact fit with the switching element through the guide feet.

[0008] As a further solution, each guide foot is connected to the main body with a flexible retractable element.

[0009] As a further embodiment, a handle limiting seat is fastened to the bottom of each guide foot, and a connecting mating part is provided on the handle limiting seat. One end of the elastic retractable member is connected to the handle limiting seat through the connecting mating part.

[0010] As a further embodiment, the main body also includes a mounting cover, which is placed inside the outer shell. The surface of the mounting cover is provided with a fixed connecting seat, and the other end of the elastic contraction member is connected to the fixed connecting seat.

[0011] As a further embodiment, a switch drive block is also included, which is connected to the guide foot or integrally connected to one of the handle limiting seats, and the machine head handle is dynamically engaged with the switch element through the switch drive block.

[0012] As a further option, the elastic contraction element is a tension spring or a strip-shaped silicone block.

[0013] As a further embodiment, the switching element is a micro switch, which enables the main body to disconnect or connect the circuit by having the guide pin or switch drive block move away from or press against the on / off key of the micro switch.

[0014] As a further embodiment, the switching element is a reed switch or a Hall switch, and a permanent magnet is provided on the guide foot or switch drive block. By moving the permanent magnet away from or close to the reed switch or Hall switch, the main body can realize the circuit disconnection or connection.

[0015] As a further solution, the side wall of the pot body is provided with two symmetrical pot handles, each pot handle is provided with a magnetic component, and a magnetic control element is provided in the main body of the main body at a position close to the magnetic component. By assembling and disassembling the main body, the magnetic control element and the magnetic component are horizontally opposed or separated, so as to realize the conduction or disconnection of the main body circuit.

[0016] The beneficial effects of this utility model are as follows:

[0017] This utility model discloses a safety structure for the air fryer head. In the default state, the elastic retraction component of the main body of this air fryer will elastically pull the handle of the head to the retracted position, without occupying the upper space of the main body, and better matching the shape of the main body to form an integrated structure, thereby improving the aesthetics of the air fryer.

[0018] When the machine head handle is in the retracted position, the machine head handle and the switching element are in contact, and the circuit of the main body controlled by the switching element is in a conductive state, waiting for the user's next operation. When the user pulls the machine head handle to the pulled position to lift the main body, the contact between the two is released the moment the machine head handle leaves the switching element, and the circuit of the main body controlled by the switching element is disconnected.

[0019] In addition, the process of the handle moving from the retracted position to the pulled-up position has an increased buffer time, which allows the hot air component to be disconnected before the main body leaves the pot. Compared with the traditional method where the hot air component is disconnected from the pot and the circuit is disconnected at the same time, this can improve the safety of the air fryer.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] Example 1:

[0030] See Figures 1 to 6As shown, a safety structure for the air fryer head includes a pot body 1. A detachable main body 2 is provided on the upper side of the pot body 1. A hot air assembly 3 is provided inside the main body 2 to deliver hot air into the inner cavity of the pot body 1. A sliding handle 4 is provided on the top surface of the main body 2. A tension spring 5 connected to the handle 4 is provided inside the main body 2. The handle 4 can be elastically reset from the pulled-up position to the retracted position through the tension spring 5. The main body 2 also has a micro switch 6 that forms a dynamic contact with the handle 4. When the handle 4 is in the pulled-up or retracted position, the circuit of the main body 2 is disconnected or connected by separating or contacting the handle 4 and the on / off switch 6.

[0031] In the default state, the tension spring 5 of the main body 2 of this air fryer will elastically pull the handle 4 of the head to the retracted position, so as not to occupy the upper space of the main body 2, and better match the shape of the main body 2 to form an integrated whole structure, thus improving the aesthetics of the air fryer.

[0032] When the machine head handle 4 is in the retracted position, the machine head handle 4 and the on / off switch of the micro switch 6 form a contact engagement, and the circuit of the main body 2 controlled by the micro switch 6 is in a conductive state, waiting for the user's next operation. When the user pulls the machine head handle 4 to the pulled position to lift the main body 2, the engagement between the two is released the instant the machine head handle 4 leaves the on / off switch of the micro switch 6, and the circuit of the main body controlled by the micro switch 6 is disconnected.

[0033] In addition, the process of the handle 4 moving from the retracted position to the pulled-up position increases the buffer time, so that the hot air assembly 3 is disconnected before the main body 2 leaves the pot body 1. Compared with the traditional method where leaving the pot body 1 and disconnecting the circuit occur at the same time, this can improve the safety of the air fryer.

[0034] The two ends of the handle 4 extend downwards with guide feet 41. The main body 2 includes a shell 21. The shell 21 has guide holes 211 that form a linear sliding fit with the guide feet 41. The micro switch 6 is located directly below the guide feet 41. The micro switch 6 forms a dynamic contact fit with the on / off switch of the micro switch 6 through the guide feet 41. Through the fit between the guide feet 41 and the guide holes 211, the handle 4 can move up and down along the lifting direction and connect with the shell 21.

[0035] Each guide foot 41 is connected to the main body 2 by a tension spring 5; the two tension springs 5 ​​provide elastic potential energy to both ends of the machine head handle 4, so that the machine head handle 4 can be evenly stressed.

[0036] Each guide foot 41 is securely connected to a handle limiting seat 42 at its bottom end. The handle limiting seat 42 is provided with a connecting mating part. One end of the tension spring 5 is connected to the handle limiting seat 42 through the connecting mating part. After the handle limiting seat 42 is installed at the bottom end of the guide foot 41, it can fix the machine head handle 4 to the outer shell 21. The connecting mating part is mainly the hook 421. The hook at one end of the tension spring 5 can be directly hooked onto the hook 421, which simplifies the installation and improves the assembly efficiency.

[0037] In addition, a lifting guide block 422 is provided on the handle limiting seat 42 on the side corresponding to the micro switch 6. A lifting guide rail 201 is provided inside the main body 2 to slide in cooperation with the lifting guide block 422. Through the cooperation between the lifting guide block 422 and the lifting guide rail 201, the guide foot 41 can slide vertically up and down, ensuring that the guide foot 41 cooperates with the on / off switch 6.

[0038] The main body 2 also includes a mounting cover 22, which is placed inside the outer shell 21. The surface of the mounting cover 22 is provided with a fixed connecting seat 221, and the other end of the tension spring 5 is connected to the fixed connecting seat 221. The fixed connecting seat 221 is also a hook structure, and the hook at the other end of the tension spring 5 can be directly hooked onto the fixed connecting seat 221.

[0039] In other embodiments, the elastic contractile element can also be a strip of silicone block, which can also provide the same contractile potential energy.

[0040] In the above structure, the cooperation between the machine head handle 4 and the micro switch 6 can only ensure that the circuit is disconnected the moment the main body 2 is lifted. After the main body 2 is placed on the table, the machine head handle 4 will return to the retracted position when the user releases it. At this time, the machine head handle 4 and the micro switch 6 will cooperate again. Therefore, in order to prevent the main body 2 from being accidentally activated when it is removed, the following safety measures are adopted:

[0041] The side wall of the pot body 1 is provided with two symmetrical pot handles 8, and each pot handle 8 is provided with a magnetic element 9. The main body 2 is provided with a magnetic control element 10 in a position close to the magnetic element 9. By assembling and disassembling the main body 2, the magnetic control element 10 and the magnetic element 9 are horizontally opposed or separated, so as to realize the conduction or disconnection of the circuit of the main body 2.

[0042] With the above structure, after the main body 2 is installed on the pot body 1, the magnetic control element 10 senses that the magnetic component 9 is in the mating position and controls the circuit of the main body 2 to be turned on. When the main body 2 is disassembled or placed in an incorrect position, the magnetic control element 10 controls the circuit of the main body 2 to be turned off instantly, so as to prevent the hot air assembly 3 from working after the main body 2 is disassembled and causing a burn accident.

[0043] In this embodiment, the hot air assembly 3 mainly includes a motor 31, a circulating fan blade 32, and a heating element 33. A heat dissipation cavity 202 is formed between the upper side of the mounting cover 22 and the outer shell 21. The motor 31 is connected to the mounting cover 22 and placed inside the heat dissipation cavity 202. A hot air cavity 203 is formed on the lower side of the mounting cover 22. The output shaft of the motor 3 extends into the hot air cavity 203 and is connected to the circulating fan blade 32. The heating element 33 is disposed below the circulating fan blade 32.

[0044] Example 2:

[0045] Example 2 differs from Example 1 in that: See Figure 7 As shown, it also includes a switch drive block 11, which is connected to the guide foot 41 or integrally connected to one of the handle limiting seats 42. The machine head handle 4 forms a dynamic contact with the micro switch 6 through the switch drive block 11; the on / off switch of the micro switch 6 is pressed by the flat abutment surface 111 at the bottom of the switch drive block 11.

[0046] Example 3:

[0047] Example 3 differs from Example 1 in that: See Figure 8 As shown, the switching element is a reed switch or Hall switch 71, and a permanent magnet 72 is provided on the guide foot 41 or the switch drive block 11. By moving away from or close to the reed switch or Hall switch 71, the main body 2 can realize the circuit disconnection or conduction.
