Description

Technical Field

[0001] The invention relates to the field of air fryers, in particular to an air fryer with good sealing performance. Background Art

[0002] Air fryers are now very popular kitchen appliances. The interior of an air fryer is usually divided into an upper control area and a lower cooking area by an air duct plate. The motor and control components are located in the control area. The motor main shaft of the motor must pass through the air duct plate and be connected to the heat circulation wind wheel. A large gap is left between the motor main shaft and the air duct plate of existing air fryers to avoid scratches and interference between the motor main shaft and the air duct plate holes due to assembly errors. However, this results in poor sealing, and the control area outside the air duct plate is at risk of being contaminated by oil smoke. Currently, there is no reliable sealing structure to solve this problem. Summary of the invention

[0003] The invention provides an air fryer with good sealing performance, a reliable sealing structure, good sealing performance and convenient installation.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an air fryer with good sealing performance, comprising an air duct plate and a motor shaft passing through a middle mounting hole of the air duct plate, the outer side of the motor shaft is sleeved with a shaft sleeve, the outer side of the shaft sleeve is sleeved with a bearing, the outer ring of the bearing is clamped in a soft sleeve, and the soft sleeve is clamped on the middle mounting hole of the air duct plate.

[0005] Preferably, a card slot is provided on the outer side of the soft cover, and the card slot is card-connected with the air duct plate, which is directly card-connected without other fasteners for installation, which is very convenient and does not require high installation accuracy.

[0006] Preferably, a middle sleeve is provided in the middle of the soft sleeve, and the bearing is arranged in the middle sleeve. The middle sleeve wraps the bearing, which can effectively position the bearing and improve the sealing performance of the soft sleeve.

[0007] Preferably, a thin sheet connection portion is provided between the edges of the middle sleeve and the soft sleeve, and the thin sheet connection portion can enhance its elasticity and ensure better operation during assembly. At the same time, during the operation of the product, the better elasticity will not affect the operation of the motor shaft.

[0008] Preferably, the shaft sleeve and the motor shaft are connected by threads, so that the installation is firm and reliable.

[0009] Preferably, an installation operation portion is provided at the upper end of the shaft sleeve, and the function of the installation operation portion is to provide a force-bearing part for the tool, so as to facilitate the installation of the shaft sleeve.

[0010] Preferably, the upper end of the shaft sleeve abuts against the cooling wind wheel on the upper side of the air duct plate, and the lower end abuts against the heat circulation wind wheel on the lower side of the air duct plate. The cooling wind wheel and the heat circulation wind wheel can be positioned by the shaft sleeve to facilitate assembly.

[0011] Preferably, a limiting member is sleeved on the motor shaft on the upper side of the cooling wind wheel, and the limiting member and the shaft sleeve can clamp the cooling wind wheel together to position it firmly.

[0012] Preferably, a gasket and a nut are sequentially sleeved on the motor shaft at the lower side of the heat cycle wind wheel, and the gasket and the nut can ensure the positioning and installation of the heat cycle wind wheel.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The combination of shaft sleeves, bearings and soft sleeves is used to seal the mounting holes of the air duct plate. The soft sleeve has a certain elasticity and can be deformed. It is easy to assemble and can ensure that even if there is an assembly error, it will not affect the assembly, and the vibration of the motor spindle fan will not affect the sealing. The shaft sleeve can also locate the cooling wind wheel and the heat circulation wind wheel for easy assembly. BRIEF DESCRIPTION OF THE DRAWINGS
