Background

Air fryer, as the kitchen use fry and bake class household electrical appliances, because its healthy culinary art way, is receiving more and more people's favor. The existing air fryer is divided into a drawer type, a flip type and a split type.

Chinese patent CN206867135U, a drawer type air fryer, which shows the most common structure of drawer type air fryer, includes an upper shell, a lower shell and a fryer, a hot air device is disposed on the upper shell, the lower shell is provided with a cavity for placing the fryer, and the front side of the cavity is provided with an opening for inserting the fryer. The drawer type fryer has the problems that the machine head serving as a heating device is fixed on a cooking cavity, a pot body is arranged in the cavity, the cooking space is limited by the size of the pot body and the cavity, the whole machine occupies large space, the whole volume is large, the whole machine is heavy and inconvenient to move, in addition, the drawer type fryer and the pot body for cooking can be drawn out for cleaning, but the machine head part is fixed above a lower shell and only can stretch into the machine head part from an opening, the cleaning is inconvenient, and the machine head part is more difficult to clean and is thorough.

Chinese patent CN206560359U, a flip-type air fryer, discloses a flip-type air fryer, in which a hot air assembly is arranged in the lid/body, and the lid is rotatably connected with and covers the body. The flip type air fryer has the problems that the machine head is hinged with the cooking cavity, the pot body or the frying basket is arranged in the cooking cavity, the cooking space is enlarged, and in order to ensure the efficiency of heating and cooking, the structure of the machine head needs to be enlarged for a long time, so that a connecting cover is arranged outside the machine head on the market and is buckled on the cooking cavity, and the connecting cover is also influenced by heat radiation, generally adopts high-temperature resistant materials, has a complex structure, and also has a huge whole structure and heavy weight; flip formula fryer, because lid and pot body are connected integratively, consequently, it can wash the locomotive portion, but when wasing, need carry the pot body part simultaneously, this kind of fryer design also is bigger, and it is inconvenient to carry, also does not do benefit to washing and portable, and the food baking temperature that the aircraft nose corresponds the department is inconsistent with the food baking temperature of connecting cover department, leads to being heated inhomogeneously, and food maturity time is different, and it is not good to toast the effect.

Chinese patent CN111743422A, a split air fryer, comprising a body, a pot body and a main machine for mounting electrical components; the machine body comprises a lower machine shell and an upper machine shell arranged on the lower machine shell, the lower machine shell is provided with an inner cavity with an opening at one side, and the pot body is detachably arranged in the inner cavity; the host is arranged on the upper shell, and a detachable structure is arranged between the lower shell and the upper shell. In this patent, the aircraft nose is detained and is put on the cup, though the components of a whole that can function independently, is convenient for wash, and it solves to cover between the upper casing, the lower casing and closes closely the problem to set up corresponding elasticity hasp. And because the elastic lock catch is arranged, the space occupied by the upper shell and the lower shell is required, and the volume of the air fryer is relatively large. Although the split frying pan adopts the split design, the existence of the elastic lock catch for connection ensures that the pan body is not easy to be thoroughly cleaned when being cleaned, and the requirement of people on sanitation and health can not be met.

The air fryer has the problems of large structure and inconvenience in carrying, and along with the improvement of living standard of people and the increase of activities such as self-driving travel, picnic and the like, the air fryer has the advantages that the volume is small, the cooking space is large enough, and the air fryer is portable, can be used for frying food and can also be used for frying less oil, so that the air fryer has a requirement.

SUMMERY OF THE UTILITY MODEL

The utility model provides a machine head of a multifunctional portable food frying and baking device aiming at the problems in the prior art; the handpiece belongs to a component of a multifunctional portable food frying and baking appliance, and can be independently used.
