Description

Technical Field

[0001] This utility model relates to the field of air fryers, specifically a safety mechanism for air fryers. 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. A heating element is located below the circulating fan blade. 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, posing a safety hazard.

[0003] Therefore, some air fryers, such as the one described in Chinese patent document (application number: 202421543547.1) which describes a safe air fryer, employ a microswitch. When the microswitch is in contact, a trigger signal is sent to the main control board via a signal transmitter, thereby activating the air fryer's operating circuit. However, since the microswitch uses mechanical transmission, the trigger element is inevitably exposed. During use, the trigger element may be affected by food residue or grease adhesion, reducing the reliability of the microswitch and posing a safety hazard. Therefore, the applicant has improved and perfected the air fryer to solve the above problems for consumers to choose from. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See Figures 1 to 4 As shown, a safety mechanism for an air fryer includes a pot body 1. A detachable main body 2 is provided on the upper side of the pot body 1. A motor 3 is provided inside the main body 2. The output shaft of the motor 3 is connected to a circulating fan blade 4. A heating element 5 is provided below the circulating fan blade 4. Two symmetrical handles 6 are provided on the side wall of the pot body 1. At least one handle 6 is provided with a magnetic element 7. A magnetic control element 8 is provided inside the main body 2 at a position close to the magnetic element 7. By assembling or disassembling the main body, the magnetic control element 8 and the magnetic element 7 can be horizontally opposed or separated, thereby realizing the conduction or disconnection of the circuit of the main body 2.

[0024] After the main unit 2 is installed on the pot body 1, the magnetic control element 7 senses that the magnetic component 7 is in the correct position and controls the circuit of the main unit 2 to conduct. When the main unit 2 is removed or placed in an incorrect position, the magnetic control element 7 controls the circuit of the main unit 2 to be disconnected instantly, which improves the safety of the air fryer and prevents the hot air from continuing to blow out after the main unit 2 is removed, thus avoiding burns.

[0025] Furthermore, the air fryer uses magnetic induction to turn the circuit on or off, which allows the magnetic component 7 and the magnetic control element 8 to be hidden in various parts of the air fryer. This prevents food residue from getting stuck or food grease from sticking to the surface, thus avoiding the failure of the safety mechanism. This ensures the reliability of the safety mechanism and prevents accidental activation, thus solving the safety hazards caused by accidental activation.

[0026] In this embodiment, the magnetic control element 8 is a reed switch or a Hall switch; and the magnetic element 7 is a permanent magnet.

[0027] Both handles 6 are equipped with magnetic components 7, and the main body 2 is equipped with two magnetic control elements 8. The two magnetic control elements 8 are arranged on the left and right sides of the main body 2 and respectively cooperate with the magnetic components 7 in the two handles 6.

[0028] When a magnetic control element 7 is configured with two magnetic components 7, the user needs to pay attention to the orientation of the main body 2 during installation. Therefore, when both handles 6 are equipped with magnetic components 7 and the main body 2 has two magnetic control elements 8, the user can place the main body 2 anywhere without paying extra attention to its orientation. In addition, during use, it is necessary to ensure that the magnetic components 7 on the left and right sides of the air fryer and the corresponding magnetic control elements 8 are engaged to conduct the circuit of the main body 2, thus avoiding situations where one side of the main body 2 is installed correctly but the other side is pushed up or lifted, or the placement is not correct.

[0029] The handle 6 extends upwards to a limiting edge 61 that is higher than the height of the pot opening of the pot body 1. The limiting edge 61 has an installation cavity 62, and the magnetic component 7 is disposed in the installation cavity 62. The limiting edge 61 can limit the movement on the one hand, and increase the height of the magnetic component 7 on the other hand, so that the magnetic component 7 and the magnetic control element 8 can be horizontally opposed, so that the magnetic control element 8 does not need to be embedded in the inner cavity of the pot body 1.

[0030] The pot body 1 is a rectangular shape with rounded corners, including two long sides at the front and back and two wide sides on the left and right. Two handles 6 are symmetrically arranged in the middle of the two wide sides and are positioned close to the pot opening. The magnetic element 7 is located in the middle of the handle. This shape of the pot body 1 ensures that the main body 2 has only two placement directions, positive and negative. After being placed in place in both directions, it can ensure that the magnetic control element 8 can cooperate with the magnetic element 7.

[0031] The main body 2 includes at least a housing 10 and a motor mounting cover 11 placed inside the housing 10. The edge of the motor mounting cover 11 extends to a cover edge 111 that connects to the bottom of the housing 10. The magnetic control element 8 is connected to the top surface of the cover edge 111. The magnetic control element 8 is arranged close to the bottom of the main body 2 to reduce the height difference between the magnetic control element 8 and the magnetic component 7.

[0032] The cover edge 111 is provided with a groove 112 that matches the shape of the magnetic component 7, and the magnetic control element 8 is positioned in the groove 112. The magnetic control element 8 is provided with a connecting through hole 801, and a connecting post 113 extends from one side of the cover edge 111 corresponding to the connecting through hole 801. By passing screws through the connecting through hole 801 and the connecting post 113, the magnetic control element 8 can be detachably installed and fastened to the cover edge 111. The groove 112 can quickly position the magnetic control element 8, and at the same time reduce the height of the magnetic control element 8. The installation is carried out by a fastening structure, which is simple in structure, improves assembly efficiency, is easy to disassemble and assemble, and is simple to operate even when maintenance and replacement are required.

[0033] The bottom of the main body 2 is fixedly connected to an annular cover plate 9, which is sealed on the pot body 1. The edge of the annular cover plate 9 is connected to a stop ring 91 that matches the opening of the pot body 1. By increasing the area of ​​the bottom surface of the main body 2 through the annular cover plate 9, the size of the main body 2 does not need to match the size of the opening of the pot body 1, so that the main body of the main body 2 can remain compact, while the pot body 1 can increase its capacity.

[0034] The annular cover 9 can be made of glass or transparent high-temperature resistant plastic; the annular cover 9 is mainly transparent, which makes it easy to observe the condition of the food in the air fryer when cooking, and helps to make timely adjustments.

[0035] The magnetic component 7 is fixed in the mounting cavity 62 by one of the following methods: integral injection molding, interference fit, adhesive bonding, snap fastening, and bottom support.

[0036] The top surface of the main body 2 is connected to a retractable handle 19. When disassembling the main body 2, the handle 19 allows the user to easily lift the entire main body 2 without having to hold it with both hands, making the operation more convenient. After the user lets go, the handle 19 can automatically retract to the top surface of the main body 2, maintaining the integrated structure of the main body.

[0037] In addition, the main body 2 is equipped with a water pump 12 and a steam generator 13. The main body 2 is equipped with a detachable water tank 14. The outlet of the water tank 14 is connected to the inlet of the steam generator 13 through a water supply pipe 15. The water pump 1251 is connected in series with the water supply pipe 15. The bottom of the main body 2 is equipped with a steam nozzle 16 facing the inner cavity of the pot. The steam outlet of the steam generator 13 is connected to the steam nozzle 16 through a steam pipe.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
