Description

Technical Field

[0001] This utility model relates to a door flip-up switch mechanism for an air fryer, which is an air fryer with a damper door structure. Background Technology

[0002] An air fryer is a new type of household appliance that uses high-speed air circulation technology to fry food. Compared to traditional electric fryers, it reduces oil content by up to 80%, is easy to clean, and is both safe and economical, making it very popular. Some ovens adopt the air fryer design, using a similar door structure that is easy to disassemble. For example, Chinese patent document CN220267462U, authorized on December 29, 2023, entitled "Small Household Appliance Outward Opening Door Flat Key Rotating Shaft Mechanism," discloses this. However, this product and similar products lack a damping force positioning structure design. Such dampers are difficult to directly apply to the opening and closing of the air fryer door, lack shock absorption, and are difficult to prevent damage to the door assembly from the impact force generated by rapid rotation. Summary of the Invention

[0003] To overcome the above shortcomings, the purpose of this utility model is to provide an air fryer with a damper door structure, thereby solving the technical problem that the existing similar products have poor door damping force positioning structure design, lack of shock absorption effect, and difficulty in avoiding damage to the door assembly caused by the impact force generated by rapid rotation. This objective is achieved through the following technical solution.

[0004] An air fryer with a damper door structure is disclosed. The air fryer has a door assembly with an opening on one side of its shell that can be opened downwards or upwards. The flip-up side of the door assembly is hinged to the opening side of the shell. The key structural design feature is that a fixed seat is symmetrically provided on one side of the shell at the hinge point of the door assembly and the shell. The door assembly corresponding to the fixed seat is provided with a damper. One end of the damper is a flat key shaft inserted into a flat key hole at one end of the fixed seat. The other end of the fixed seat is fixedly set in the shell. The other end of the damper, the damping box, is fixedly set in the door assembly. The door assembly is positioned and flipped open by the damper.

[0005] The damper has a raised baffle on one side of the outer diameter of the damping box. When the door assembly is flipped closed, the baffle of the damper abuts against the opening of the housing.

[0006] The keyed shaft of the damper is a hydraulic shaft. A piston is installed on the outer diameter of the keyed shaft inside the damping housing. A spring is installed at the bottom of the keyed shaft inside the damping housing, and hydraulic return oil is filled in. A return oil chamber communicating with the inside of the damping housing is provided on one side of the baffle. The external thread of the nut is fixed to the inner diameter of the cavity at the opening of the damping housing. The above is a specific embodiment of the damper, which is a hydraulic structure device, thereby adjusting the damping force of the spring through the nut.

[0007] The damper's key shaft, stop bar, and damping housing are integrally cast. The damping housing opening at the extended end of the key shaft contains sequentially arranged anti-detachment washers. Damping washers are located on both sides of the anti-detachment washers on the key shaft within the damping housing. The anti-detachment washers and damping washers are fixed to the key shaft within the damping housing by the internal thread of a nut. This is another specific embodiment of the damper, allowing adjustment of the damping force between the anti-detachment washers via the nut.

[0008] This utility model has a reasonable structural design, good door stability and safety, and low production cost; it is suitable for use as an air fryer with a damper door structure, as well as for structural improvements of similar products. Attached Figure Description

[0014] The structure and use of this utility model will now be further described with reference to the accompanying drawings. Figures 1-2As shown, the air fryer has a door assembly 1 with a downward-opening hinge on one side of its shell. The hinged side of the door assembly is connected to the open side of the shell via a hinge. A mounting base 5 is symmetrically located on one side of the shell at the hinge point of the door assembly. A damper 4 is provided on the door assembly corresponding to the mounting base. One end of the damper, a flat key shaft 401, is inserted into a flat key hole at one end of the mounting base. The other end of the mounting base is fixed to the shell, and the other end of the damper, a damping housing, is fixed to the door assembly. The door assembly is positioned and flipped open by the damper. Simultaneously, a protruding stop 402 is provided on the outer diameter of one side of the damping housing of the damper. When the door assembly is flipped closed, the stop 402 abuts against the opening of the shell.

[0015] like Figure 3 As shown, the key shaft of the damper is a hydraulic shaft. The outer diameter of the key shaft inside the damping box is provided with a piston 404. The bottom of the key shaft inside the damping box is provided with a spring 405 and filled with hydraulic return oil. The side of the baffle 402 of the damping box is provided with a return oil cavity that communicates with the inside of the damping box. The external thread of the nut 403 is fixed to the inner diameter of the cavity at the opening of the damping box.

[0016] like Figure 4 As shown, or, the key shaft, the stop bar, and the damping box body of the above-mentioned damper are integrally cast. The damping box body opening at the end of the key shaft is provided with anti-detachment pads 406 arranged in sequence. Damping pads 407 are provided on both sides of the anti-detachment pads on the key shaft inside the damping box body. The anti-detachment pads and the damping pads are fixed to the key shaft inside the damping box body by the internal thread of the nut.

[0017] This air fryer features a damper mounted on the door assembly. The damper's keyed shaft is inserted into the keyed hole of the mounting base, causing the damper's rotating end to rotate when the door assembly is opened and closed. The damper utilizes a hydraulic structure or damping plate structure internally, providing excellent shock absorption. Compared to ordinary hinge structures, its performance is superior, resulting in a better user experience.

[0018] When the door assembly is opened, the damper's key shaft smoothly decelerates and stops at the desired position during rotation, effectively preventing damage to the door assembly caused by the impact force generated by rapid rotation.
