Detailed Description

The following description will be made with reference to the accompanying drawings.

As specific embodiment, the utility model discloses a multi-functional air fryer seal structure of embodiment, it is including establishing pot lid 1, and pot lid 1 is provided with heat-generating body 8 and possesses rotary power's rotatory power axle 2, and rotatory power axle 2 is connected with interior fan blade 3. The pot cover body 1 may be manufactured by die casting, may be manufactured by riveting and turning after stamping, and may be manufactured by other methods.

The rotary power shaft 2 is a rotary output shaft of the motor 29 and is provided with rotary power, and may be provided with rotary power by other conventional means, such as by gear transmission.

The heating element 8 is a heating element for generating heat, such as an electric heating tube or the like.

One end of the rotary power shaft 2 connected with the inner fan blade 3 is an inner blade connecting end 23, and the rotary power shaft 2 drives the inner fan blade 3 to rotate, so that the inner fan blade 3 pushes air, and the air flows.

The method comprises the steps of placing cooked objects such as meat in an inner cavity (not shown in the drawing) of a pot body 9, installing a pot cover assembly (not shown in the drawing) to the pot body 9 to seal the inner cavity of the pot body 9, starting a heating body 8 and a motor 29 to enable air to be heated by the heating body 8 and flow in the inner cavity of the pot body 9, and accordingly achieving the function of an air fryer.

Place the inner chamber of pot body 9 with cooked object such as rice and water to install the pot cover subassembly to pot body 9 and seal the inner chamber of pot body 9, start pot body 9 and make pot body 9 generate heat, carry out high-pressure cooking with cooked object such as rice and water and realize the function of pressure cooker.

The utility model discloses a multi-functional air fryer seal structure of embodiment still includes shaft seal 4.

The rotary power shaft 2 includes a contacted portion 21 having a circular cross section.

The shaft seal 4 comprises a shaft seal body 41 and a shaft seal carrier 42 which is fixedly connected to the pot cover 1. For example, the pot cover body 1 is provided with a mounting groove 14, and the shaft seal carrier 42 is embedded in the mounting groove 14, so that the shaft seal carrier 42 and the pot cover body 1 are fixedly connected by means of interference fit, glue bonding and the like. The edge of the cross-section of the shaft seal carrier 42 is circular, but may also be polygonal, for example, to facilitate the installation of the shaft seal 4. The bottom end of shaft seal body 41 projects downward beyond the bottom end of shaft seal body 41. When embedding shaft seal carrier 42 into mounting groove 14, shaft seal carrier 42's bottom offsets with the end inner wall of mounting groove 14 earlier and realizes spacingly, can prevent that the end inner wall of shaft seal body 41 bottom mounting groove 14 from offsetting, and unable deformation and inefficacy is convenient for install shaft seal 4 simultaneously.

The tip of the shaft seal body 41 is fixedly connected to the shaft seal carrier 42.

The cross section of the shaft sealing body 41 is circular ring-shaped, and the inner diameter and the outer diameter of the circular ring shape are gradually reduced from top to bottom. For example, the inner edge and the outer edge of the longitudinal section of the shaft sealing body 41 are both straight lines, and the straight lines are close to the rotation axis of the rotation power shaft 2 from top to bottom, so that the inner diameter of the circular ring shape is gradually reduced from top to bottom; the upward-downward direction refers to the direction from the pot cover body 1 to the pot body 9. Of course, the inside of the vertical section of the shaft seal body 41 may be a curved line such as an arc line.

And the rotating axis lead of the rotating power shaft 2 passes through the circle center of the circle and the circle center of the circular ring.

The shaft seal 41 has elasticity, and the bottom end of the shaft seal 41 is a contact end 411, and the contact end 411 abuts against the contacted part 21.

The operating principle is that when the inner cavity of the pot body 9 generates high pressure, the high-pressure air pushes the outer side of the shaft sealing body 41, so that the whole shaft sealing body 41 has a tendency of being close to the contacted part 21, the shaft sealing body 41 is tightly attached to the contacted part 21, and a high-pressure sealing effect is achieved.

As a specific embodiment, a relief gap 421 is provided between the inner side of the shaft seal carrier 42 and the rotating power shaft 2, so that the shaft seal carrier 42 cannot contact with the rotating power shaft 2, for example, the longitudinal section of the shaft seal carrier 42 is generally L-shaped, so that the inner cavity of the shaft seal carrier 42 is circular with a diameter larger than that of the rotating power shaft 2. The thickness of the bottom end of the shaft sealing body 41 is gradually reduced from inside to outside, and the innermost side of the bottom end of the shaft sealing body 41 is theoretically a circular line, for example, the bottom end face of the shaft sealing body 41 is a horizontal plane (i.e., a plane corresponding to the cross section), so that the thickness of the bottom end of the shaft sealing body 41 is gradually reduced from inside to outside. When the air fryer function is used, the pressure of the inner cavity of the boiler body 9 is not large, the requirement on the sealing performance of the inner cavity of the boiler body 9 is not high, the pressure is low or no pressure is applied to the shaft sealing body 41 at the moment, the deformation is small or no deformation is applied, the contact area between the innermost side of the bottom end of the shaft sealing body 41 and the contacted part 21 is small, theoretically, only line contact can be realized, the resistance to the rotating power shaft 2 is small, and therefore high-speed rotation of the rotating power shaft 2 at low pressure can be ensured.

In a specific embodiment, the circular shape of the cross section of the contacted portion 21 is gradually reduced from top to bottom.

As shown in fig. 7, as a specific embodiment, the inner edge of the vertical section of the shaft sealing body 41 and the edge of the vertical section of the contacted part 21 are both straight lines, and the angle between the straight line of the contacted part 21 and the rotation axis of the rotation power shaft 2 is smaller than the angle between the straight line of the shaft sealing body 41 and the rotation axis of the rotation power shaft 2, in other words, the straight line of the contacted part 21 is more nearly parallel to the vertical direction (the rotation axis of the rotation power shaft 2) as shown in fig. 7. When the inner cavity of the pot body 9 generates high pressure, the high-pressure air pushes the outer side of the shaft sealing body 41, so that the shaft sealing body 41 tends to be close to the contacted part 21, and the larger the high-pressure is, the larger the pressure and/or the contact area of the shaft sealing body 41 against the contacted part 21 is, and the high-pressure sealing effect can be improved.

In a specific embodiment, the inner edge and the outer edge of the vertical section of the shaft seal body 41 are both straight and parallel to each other. The shaft sealing body 41 can be easily and integrally elastically deformed, the contact area of the contacted part 21 is supported by the shaft sealing body 41 when the high pressure is generated, and the high pressure sealing effect is improved.

The utility model discloses a pot seal structure is fried to multi-functional air still establishes the bearing 7 on rotatory power shaft 2 including the cover, and the outer lane of bearing 7 offsets with 1 fixed connection of the pot lid body and the top of the axle seal body 41. For example, the bearing 7 is inserted into the mounting groove 14 to realize fixed connection. Facilitating the mounting of the bearing 7 and the shaft sealing body 41.
