[0032] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] See also Figure 1 and Figure 2 An embodiment of the present invention provides a cooking appliance 1000, which may be an air fryer, an air oven, a frying-and-roasting machine, or other cooking appliances.

[0035] The cooking appliance 1000 includes a fan assembly 100 and a driving device 200 . The fan assembly 100 is detachably mounted on a driving shaft 201 of the driving device 200 . The driving device 200 can drive the fan assembly 100 to rotate to achieve the functions required by the cooking appliance 1000 .

[0036] In some embodiments, the cooking appliance 1000 may have the following structural form. For example, the cooking appliance 1000 may also include a body 302 and a panel 307. The body 302 may have a cooking cavity 308. The fan assembly 100 is located in the cooking cavity 308 to facilitate the air flow in the cooking cavity 308.

[0037] The panel 307 may be opposite to the cooking cavity 308, the main structure 202 of the driving device 200 may be located on the side of the panel 307 away from the cooking cavity 308, and the driving shaft 201 of the driving device 200 is disposed through the panel 307. In this way, the panel 307 helps to provide a certain barrier for the main structure 202 of the driving device 200, so that the oil stains in the cooking cavity 308 are not easy to adhere to the main structure 202 of the driving device 200. The panel 307 may be glass.

[0038] In some embodiments, the cooking appliance 1000 may further include an upper cover 301, and structures such as a panel 307, a driving device 200, and a fan assembly 100 may be assembled on the upper cover 301. The upper cover 301 may include components such as a heat dissipation fan 303, a heat insulation cover 304, a reflective cover 305, and a light wave tube 306 from top to bottom, and the panel 307 may be located below the light wave tube 306. The body 302 may further include components such as an inner pot 309 and a baking tray 310. The fan assembly 100 may be located above the cooking cavity 308 and below the panel 307, and the driving device 200 may be located above the heat dissipation fan 303, and the driving device 200 may drive the heat dissipation fan 303 and the fan assembly 100 to rotate. In the normal cooking process, the light wave tube 306 may radiate energy through the panel 307 to the food on the baking tray 310 by direct radiation and reflection. A heating plate 311 may be provided at the bottom of the inner pot 309, and the heating plate 311 directly transfers heat to the cooking cavity 308. In this way, the cooking utensil 1000 can heat the food more evenly by heating up and down, and avoid turning over. The heat dissipation fan 303 and the fan assembly 100 can rotate coaxially, and the heat dissipation fan 303 can discharge the excess heat in the upper cover 301 to the outside of the cooking utensil 1000. The fan assembly 100 is used in the cooking cavity 308 to stir the air in the cooking cavity 308 to drive the hot air flow. Since the fan assembly 100 is in direct contact with the oil smoke generated by the high temperature of the food, a large amount of oil stains will be attached over time, and the fan assembly 100 needs to be cleaned.

[0039] Since the fan of the cooking appliance in the related art is generally fixedly connected to the motor shaft, it is difficult to remove it for cleaning. In the present invention, when the fan assembly 100 needs to be cleaned, the fan assembly 100 can be quickly removed from the drive shaft 201 of the drive device 200, which effectively improves the cleaning efficiency. After the fan assembly 100 is removed, the fan assembly 100 does not block the panel 307, which is convenient for the user to clean the panel 307; after the fan assembly 100 is cleaned, the fan assembly 100 can also be reassembled on the drive shaft 201 of the drive device 200, so that the drive device 200 can drive the fan assembly 100 to rotate to achieve the functions required by the cooking appliance 1000.

[0040] In some embodiments, the driving device 200 may be a driving motor or other driving structures.

[0041] In some embodiments, the main structure 202 of the driving device 200 may be a base housing, a stator, a magnet, and other structures of a driving motor.

[0042] In some embodiments, the driving shaft 201 of the driving device 200 may be an output shaft of a driving motor, or an output shaft drivingly connected to the driving motor.

[0043] See also Figures 3 to 5 The fan assembly 100 includes a fan body 10 , a connecting sleeve 20 and a locking member 30 . The connecting sleeve 20 is disposed on the fan body 10 , and the locking member 30 is disposed between the fan body 10 and the connecting sleeve 20 .

[0044] The fan body 10 includes a fan blade 11 and a mounting member 12, and the fan blade 11 is connected to the mounting member 12. The mounting member 12 can be adapted to be installed in the driving shaft 201 of the driving device 200, and the fan blade 11 can be driven by the driving device 200 to rotate to generate wind.

[0045] An axial hole 121 is provided in the axial direction of the mounting member 12 . The axial hole 121 is suitable for accommodating a driving shaft 201 of the driving device 200 , so that the driving shaft 201 of the driving device 200 can be inserted into the mounting member 12 .

[0046] In some embodiments, the mounting member 12 may be generally in the shape of a column, for example, the mounting member 12 may be generally in the shape of a cylinder, an elliptical column, a square column, a triangular prism, a quadrangular prism, a pentagonal prism or other shapes.

[0047] In some embodiments, the shaft hole 121 may be provided on an end surface of the mounting member 12 , for example, the shaft hole 121 may be provided on an end surface of the mounting member 12 close to the fan blade 11 .

[0048] In some embodiments, see Figure 6 The mounting member 12 may have an inner side surface 122 , and the inner side surface 122 may surround the above-mentioned axial hole 121 .

[0049] In some embodiments, the shaft hole 121 may be a through hole structure, for example, the shaft hole 121 may pass through two opposite end surfaces of the mounting member 12. In some other embodiments, the shaft hole 121 may also pass through one end surface of the mounting member 12.

[0050] In some embodiments, the shaft hole 121 may be a non-circular hole, for example, the shaft hole 121 may be substantially an elliptical hole, a triangular hole, a quadrilateral hole, a pentagonal hole, a hexagonal hole or other shapes.

[0051] A through hole 123 is provided in the radial direction of the mounting member 12 . The through hole 123 is communicated with the shaft hole 121 . The through hole 123 is convenient for accommodating the locking member 30 .

[0052] In some embodiments, the through hole 123 may be disposed on a side surface of the mounting member 12 .

[0053] In some embodiments, the mounting member 12 may further have an outer side surface 124 , and the through hole 123 may penetrate the inner side surface 122 and the outer side surface 124 .

[0054] In some embodiments, the center line of the through hole 123 and the center line of the shaft hole 121 may be arranged at an angle.

[0055] For example, the center line of the through hole 123 and the center line of the shaft hole 121 may be substantially perpendicular to each other, wherein the center line of the through hole 123 and the center line of the shaft hole 121 may be inclined to each other within the range of manufacturing error.

[0056] For example, the angle between the center line of the through hole 123 and the center line of the axial hole 121 can be an acute angle, wherein the angle between the center line of the through hole 123 and the center line of the axial hole 121 can be approximately 89 degrees, 88 degrees, 87 degrees, 86 degrees, 85 degrees, 80 degrees, 75 degrees, 70 degrees, 65 degrees, 60 degrees, etc.

[0057] For another example, the angle between the center line of the through hole 123 and the center line of the axial hole 121 can be an obtuse angle, wherein the angle between the center line of the through hole 123 and the center line of the axial hole 121 can be approximately 91 degrees, 92 degrees, 93 degrees, 94 degrees, 95 degrees, 100 degrees, 105 degrees, 110 degrees, 115 degrees, 120 degrees, etc.

[0058] In some embodiments, the inner diameter of the through hole 123 may increase from the inner side surface 122 to the outer side surface 124 of the mounting member 12 .

[0059] For example, the inner diameter of the through hole 123 may gradually increase from the inner side surface 122 to the outer side surface 124 , and the through hole 123 may be substantially a tapered hole.

[0060] For another example, the through hole 123 may have a plurality of hole segments with different inner diameters and connected to each other. The inner diameter of the hole segment close to the outer side surface 124 of two adjacent hole segments is larger than the inner diameter of the hole segment close to the inner side surface 122. Then the through hole 123 may be generally a stepped hole, a countersunk hole, a countersunk hole, or the like.

[0061] For another example, the through hole 123 may have a first hole section and a second hole section that are connected, the first hole section may pass through the outer side surface 124 of the mounting member 12, the second hole section may pass through the inner side surface 122 of the mounting member 12, and the inner diameter of the second hole section may be smaller than the inner diameter of the first hole section. The first hole section and the second hole section may both be hole sections with constant inner diameters; or the inner diameter of the first hole section may gradually increase from the second hole section toward the outer side surface 124, and the second hole section may be a hole section with constant inner diameter; or the second hole section may be a hole section with constant inner diameter, and the inner diameter of the second hole section may gradually increase from the inner side surface 122 toward the first hole section.

[0062] For another example, the through hole 123 may have a first hole segment, a second hole segment, and a third hole segment that are connected in sequence, the first hole segment may pass through the outer side surface 124 of the mounting member 12, the third hole segment may pass through the inner side surface 122 of the mounting member 12, the inner diameter of the third hole segment may be smaller than the inner diameter of the second hole segment, and the inner diameter of the second hole segment may be smaller than the inner diameter of the first hole segment. Among them, the first hole segment, the second hole segment and the third hole segment can all be hole segments with constant inner diameters; or, the inner diameter of the first hole segment can gradually increase from the second hole segment toward the outer side surface 124, and the second hole segment and the third hole segment can both be hole segments with constant inner diameters; or, the inner diameter of the first hole segment can gradually increase from the second hole segment toward the outer side surface 124, the second hole segment can be a hole segment with constant inner diameter, and the inner diameter of the third hole segment can gradually increase from the inner side surface 122 toward the second hole segment; or, the first hole segment and the second hole segment can both be hole segments with constant inner diameters, and the inner diameter of the third hole segment can gradually increase from the inner side surface 122 toward the second hole segment; or, the first hole segment can be a hole segment with constant inner diameter, the inner diameter of the second hole segment can gradually increase from the second hole segment toward the outer side surface 124, and the third hole segment can be a hole segment with constant inner diameter.

[0063] In some embodiments, the opening formed by the through hole 123 penetrating the outer side surface 124 can be substantially circular, elliptical, triangular, quadrilateral, pentagonal, hexagonal or other shapes.

[0064] In some embodiments, the opening formed by the through hole 123 penetrating the inner side surface 122 can be substantially circular, elliptical, triangular, quadrilateral, pentagonal, hexagonal or other shapes.

[0065] In some embodiments, the number of through holes 123 may be multiple, and the multiple through holes 123 may be distributed around the center line of the shaft hole 121, and each through hole 123 is connected to the shaft hole 121. In the present invention, the term "multiple" means greater than or equal to two. For example, the number of through holes 123 may be two, three, four, five, six or other numbers. In the case of a light load or a low speed, the number of through holes 123 may be only one, and the matching locking member 30 is also only one.

[0066] In some embodiments, when there are plural through holes 123 , there may be no height difference between the centers of the plurality of through holes 123 .

[0067] For example, in some embodiments, the number of the through holes 123 may be two, and the centers of the two through holes 123 may be symmetrically distributed about the central axis of the shaft hole 121 .

[0068] For example, in some embodiments, the number of the through holes 123 may be two, and a line connecting the centers of the two through holes 123 may be perpendicular to the center line of the shaft hole 121 .

[0069] For example, in some embodiments, the number of the through holes 123 may be three or more, and a plane passing through the centers of the three or more through holes 123 may be perpendicular to the center line of the shaft hole 121 .

[0070] In some embodiments, see Figure 5 and Figure 2 The fan blade 11 may be a metal part, so that the light wave tube 306 can conduct the generated heat to the fan blade 11, so that the fan blade 11 can also generate heat, thereby helping to improve the heating effect of the cooking utensil 1000. In other embodiments, the fan blade 11 may be a plastic part.

[0071] In some embodiments, the fan blade 11 can be an iron fan, for example, the fan blade 11 can be made of pig iron, or can be made of iron alloys such as steel and cast iron. In this way, the fan blade 11 is easy to process and shape, which helps to simplify the manufacturing difficulty and manufacturing cost of the fan blade 11.

[0072] In some embodiments, the fan blade 11 can be manufactured by sheet metal processing.

[0073] In some embodiments, the mounting member 12 may be a metal member. In other embodiments, the mounting member 12 may be a plastic member.

[0074] In some embodiments, the fan body 10 may be an integral structure. For example, the fan blades 11 and the mounting member 12 may be integrally formed by a mold. For another example, the fan blades 11 and the mounting member 12 may be connected to each other by threaded connection, gluing, welding, fasteners or other methods after they are formed.

[0075] See also Figure 6 The locking member 30 is movably located in the through hole 123. For example, the locking member 30 can be moved toward the shaft hole 121 under the action of an external force, or in another example, the locking member 30 can be moved away from the shaft hole 121 under the action of an external force, so that the locking member 30 can be close to or away from the shaft hole 121.

[0076] In some embodiments, the locking member 30 may be substantially spherical, and the locking member 30 may be rotatably located in the through hole 123 , so that the locking member 30 may be easily moved and changed in position under the action of an external force.

[0077] In some embodiments, the locking member 30 may be a hard structure, such as a metal member, a steel ball, a copper ball, an iron ball or other structures.

[0078] In some embodiments, the number of the locking member 30 may be one, and the locking member 30 may be located in one of the plurality of through holes 123 .

[0079] In some embodiments, there may be a plurality of locking members 30 , for example, the number of the locking members 30 is consistent with the number of the through holes 123 , and each locking member 30 may be located in a corresponding one of the through holes 123 .

[0080] The connecting sleeve 20 is movably mounted on the mounting member 12 along the axial direction of the mounting member 12, and the connecting sleeve 20 is selectively moved to a locked position or an unlocked position along the axial direction of the mounting member 12. Figure 6 As shown, when the driving shaft 201 of the driving device 200 is installed into the shaft hole 121, the connecting sleeve 20 drives the locking member 30 to abut against the driving shaft 201 to be in the locked position, and the locking member 30 can lock the driving shaft 201 and the fan assembly 100. Figure 7 As shown, the connecting sleeve 20 provides the locking member 30 with a radial movement away from the driving shaft 201 so as to be in an unlocked position, thereby facilitating the removal of the fan assembly 100 from the driving shaft 201 .

[0081] The direction in which the connecting sleeve 20 moves from the unlocking position to the locking position is referred to as the locking direction D1 , and the direction in which the connecting sleeve 20 moves from the locking position to the unlocking position is referred to as the unlocking direction D2 .

[0082] When it is necessary to remove the fan assembly 100 from the drive shaft 201 of the drive device 200, the user can pull the connecting sleeve 20 to move the connecting sleeve 20 to the unlocking position relative to the fan body 10 (or the mounting member 12) along the unlocking direction D2, and the locking member 30 loses the connecting sleeve 20 to provide the locking member 30 with abutting force on the drive shaft 201. At this time, the entire fan assembly 100 can slide down under the action of gravity, or the user can increase the force to pull down the connecting sleeve 20 to make the shaft hole 121 of the fan body 10 (or the mounting member 12) disengage from the drive shaft 201, thereby realizing the removal of the fan assembly 100 from the drive shaft 201. Figure 8 shown.

[0083] When it is necessary to reassemble the fan assembly 100 to the drive shaft 201 of the drive device 200, the user can directly align the axial hole 121 of the fan body 10 (or the mounting member 12) with the drive shaft 201, and then guide the entire fan assembly 100 so that the drive shaft 201 is inserted into the axial hole 121, and move the connecting sleeve 20 along the locking direction D1 relative to the fan body 10 (or the mounting member 12) to the locked position. At this time, the connecting sleeve 20 provides a force for the locking member 30 to abut against the drive shaft 201, thereby achieving the installation of the fan assembly 100 on the drive shaft 201.

[0084] In this way, the connecting sleeve 20 can switch between a locked position and an unlocked position through axial movement, so that the drive shaft 201 and the fan assembly 100 are easy to disassemble and assemble, thereby facilitating the removal of the fan assembly 100 from the drive shaft 201 for cleaning, which helps to simplify the cleaning operation and improves the problem of being unable to clean due to the inconvenience of using tools to disassemble and assemble in a small space. After cleaning, it also helps to quickly connect the fan assembly 100 to the drive shaft 201, making installation convenient, quick and efficient.

[0085] In some embodiments, see Figure 6 When the connecting sleeve 20 moves to the locked position, the locking member 30 can be partially located in the shaft hole 121, so that the locking member 30 can protrude from the through hole 123 into the shaft hole 121, which helps to improve the locking ability of the locking member 30 on the drive shaft 201.

[0086] In some embodiments, the drive shaft 201 may be provided with a slot 2011, and the slot 2011 may be provided on the outer peripheral surface of the drive shaft 201. When the connecting sleeve 20 moves to the locking position, the locking member 30 may be partially located in the slot 2011. In this way, the stability of the locking fit between the locking member 30 and the drive shaft 201 is improved, so that the fan assembly 100 and the drive shaft 201 are not easily separated from each other.

[0087] In some embodiments, the width of the slot 2011 along the axial direction of the drive shaft 201 can be reduced from the outer circumference of the drive shaft 201 to the inside of the drive shaft 201. In this way, after the connecting sleeve 20 moves to the unlocking position, it is helpful to facilitate the locking member 30 to be separated from the slot 2011 of the drive shaft 201 during the process of pulling the fan assembly 100 to separate the drive shaft 201 from the shaft hole 121.

[0088] In some embodiments, the outer diameter of the locking member 30 may be larger than the minimum diameter of the through hole 123 , which helps prevent the locking member 30 from detaching from the through hole 123 from the inner side surface 122 of the mounting member 12 , thereby helping to ensure the reliability of the detachable function of the fan assembly 100 .

[0089] In some embodiments, the connecting sleeve 20 may include a sliding sleeve 21 and a stopper 22, wherein the stopper 22 is disposed on the sliding sleeve 21. The sliding sleeve 21 is movably sleeved on the mounting member 12 along the axial direction of the mounting member 12. The stopper 22 may be protruding from the inner wall 211 of the sliding sleeve 21, and the stopper 22 may be located between the two axial ends of the sliding sleeve 21.

[0090] When the connecting sleeve 20 is in the locked position, the limit block 22 can abut against the locking member 30; when the connecting sleeve 20 is in the unlocked position, the inner wall 211 can be opposite to the locking member 30. In this way, since the limit block 22 is protruding from the inner wall 211 of the sliding sleeve 21, the distance between the limit block 22 and the outer peripheral surface of the mounting member 12 is smaller than the distance between the inner wall 211 of the sliding sleeve 21 and the outer peripheral surface of the mounting member 12. Therefore, the connecting sleeve 20 in the locked position abuts against the locking member 30 through the limit block 22, which helps to increase the radial force on the drive shaft 201, so that the fan assembly 100 is not easy to slip off the drive shaft 201. In addition, the connecting sleeve 20 in the unlocked position is relative to the locking member 30 through the inner wall 211, which helps provide a suitable radial movement space for the locking member 30, so that when the drive shaft 201 is disengaged from the axial hole 121 of the fan assembly 100, the locking member 30 can move in a direction away from the drive shaft 201 under the touch of the drive shaft 201, which helps to avoid obstruction to the drive shaft 201.

[0091] In some embodiments, the sliding sleeve 21 may be substantially annular.

[0092] In some embodiments, the distance between the inner wall 211 of the sliding sleeve 21 and the mounting member 12 may be smaller than the outer diameter of the locking member 30. Thus, when the connecting sleeve 20 is in the unlocked position, it helps to prevent the locking member 30 from escaping from the through hole 123 from the outer side surface 124 of the mounting member 12.

[0093] In some embodiments, the limiting block 22 may be substantially ring-shaped.

[0094] In some embodiments, the limiting block 22 may have a limiting surface 221 , and the limiting surface 221 of the connecting sleeve 20 in the locked position abuts against the locking member 30 .

[0095] The distance between the limit surface 221 and the outer peripheral surface of the mounting member 12 can be increased along the locking direction D1, so that the limit surface 221 is set at an angle, thereby facilitating that the locking member 30 can better abut against the drive shaft 201 under the pushing action of the limit surface 221 during the process of the connecting sleeve 20 moving from the unlocking position to the locking position, thereby helping to avoid the situation where the limit block 22 and the locking member 30 become stuck during the locking process of the connecting sleeve 20.

[0096] In some embodiments, the longitudinal section of the limiting block 22 may be substantially an oblique line at the limiting surface 221 , so that the limiting surface 221 may be substantially a conical surface.

[0097] In some embodiments, the longitudinal section of the limiting block 22 at the limiting surface 221 may be substantially an arc, so that the limiting surface 221 may be substantially a spherical surface.

[0098] In some embodiments, the stop block 22 and the sleeve 21 may be an integral structure. For example, the stop block 22 and the sleeve 21 may be integrally formed by a mold. For another example, after the stop block 22 and the sleeve 21 are formed separately, they may be connected together by threaded connection, gluing, welding, fasteners or other methods.

[0099] In some embodiments, the fan assembly 100 may further include a handle 40, which may be sleeved outside the connection sleeve 20, for example, the handle 40 may be sleeved outside the sliding sleeve 21, and the handle 40 facilitates the user to operate the fan assembly 100. In other embodiments, the fan assembly 100 may not have an additional handle 40, so that the user can directly operate the fan assembly 100 by holding the outer peripheral surface of the connection sleeve 20.

[0100] In some embodiments, the handle 40 may have a limiting end surface 41 and an opening 42, and the limiting end surface 41 and the opening 42 are opposite to each other. The limiting end surface 41 may face the fan blade 11, and the opening 42 may face away from the fan blade 11.

[0101] The direction from the limiting end face 41 toward the opening 42 can be the unlocking direction D2. In this way, when the user pulls the handle 40 along the unlocking direction D2, the limiting end face 41 of the handle 40 can abut against the sliding sleeve 21 and can drive the connecting sleeve 20 to move; when the connecting sleeve 20 moves to the unlocking position, the limiting end face 41 can also block the locking member 30, which helps to avoid the situation where the locking member 30 is separated from the sliding sleeve 21 when the user pulls the handle 40 with excessive force.

[0102] In some embodiments, the handle 40 and the connecting sleeve 20 can be fixedly connected by interference fit. The handle 40 and the connecting sleeve 20 can also be fixedly connected by glue. In other embodiments, the handle 40 and the connecting sleeve 20 can also be fixed by other methods.

[0103] In some embodiments, the fan assembly 100 may further include a cover 50, which may be connected to the side of the handle 40 away from the fan blades 11, and the outer diameter of the cover 50 may expand in a direction away from the handle 40. In this way, the cover 50 can provide support and limit for the user's hand, so that the user is not easily unable to hold the handle 40 due to slipping when pulling the handle 40. In addition, since the outer diameter of the cover 50 expands in a direction away from the handle 40, it avoids the situation where the cover 50 is designed as an upward flip structure (i.e., the outer diameter of the cover 50 expands from the opening 42 of the handle 40 in a direction toward the limit end surface 41 of the handle 40), which causes the accumulation of smoke oil at the connection between the cover 50 and the handle 40.

[0104] In some embodiments, the cover body 50 and the handle 40 may be an integral structure. For example, the cover body 50 and the handle 40 may be integrally formed by a mold. For another example, the cover body 50 and the handle 40 may be connected to each other by threaded connection, gluing, welding, fasteners or other methods after they are formed.

[0105] In some embodiments, the fan assembly 100 can also connect the cover 50 to the connecting sleeve 20 without adding the handle 40. Figure 10 to Figure 11 The cover body 50 can be connected to the side of the connecting sleeve 20 away from the fan blade 11, and the outer diameter of the cover body 50 increases in the direction away from the connecting sleeve 20.

[0106] In this way, the cover body 50 can also provide support and limit for the user's hand, so that the user will not easily slip and fail to hold the connecting sleeve 20 when pulling the connecting sleeve 20. In addition, since the outer diameter of the cover body 50 is enlarged in the direction away from the connecting sleeve 20, the situation that the cover body 50 is designed as an upward flip structure and the smoke oil is accumulated at the connection between the cover body 50 and the connecting sleeve 20 is avoided.

[0107] In some embodiments, the cover body 50 and the connecting sleeve 20 may be an integral structure. For example, the cover body 50 and the connecting sleeve 20 may be integrally formed by a mold. For another example, after the cover body 50 and the connecting sleeve 20 are formed separately, they may be connected to one another by threaded connection, gluing, welding, fasteners or other methods.

[0108] See also Figure 8 or Fig.10 In some embodiments, the fan assembly 100 may further include a limit member 60 and an elastic return member 70 . The limit member 60 may be connected to the end of the mounting member 12 away from the fan blade 11 , and the elastic return member 70 may be abutted between the connecting sleeve 20 and the limit member 60 .

[0109] The elastic return member 70 may be adapted to provide an elastic force along the locking direction D1 for the connecting sleeve 20 , so that the connecting sleeve 20 can be kept in the locked position, which helps to improve the stability of the connection between the fan assembly 100 and the drive shaft 201 .

[0110] In addition, the limit member 60 can provide support for the user's fingers. For example, when the fan assembly 100 needs to be removed from the drive shaft 201, the user can press the limit member 60 with the thumb, and the index finger and middle finger can clamp the handle 40 or the cover body 50 and pull down hard, so that the connecting sleeve 20 can be moved to the unlocked position more conveniently.

[0111] In some embodiments, the elastic reset member 70 may be a spring. For example, the elastic reset member 70 may be a compression spring, and the elastic reset member 70 may be in a compressed state. The degree of compression of the elastic reset member 70 when the connecting sleeve 20 is in the unlocked position may be greater than the degree of compression when the connecting sleeve 20 is in the locked position.

[0112] In some embodiments, the limit member 60 can be partially inserted into the connecting sleeve 20, for example, the limit member 60 can be partially inserted into the sliding sleeve 21, which helps to prevent oil smoke from entering the sliding sleeve 21, helps to reduce oil accumulation and affect the normal operation of structures such as the locking member 30 and the elastic reset member 70.

[0113] In some embodiments, a user or worker may assemble the fan assembly 100 according to the following process. Figure 4 , the user or worker can first align the limiting end face 41 of the handle 40 with the mounting member 12 of the fan body, and then sleeve the handle 40 on the outside of the mounting member 12; then place the locking member 30 at the through hole 123 from the outer side surface 124 of the mounting member 12, and then sleeve the connecting sleeve 20 on the outside of the mounting member 12 and inside the handle 40, and make the end of the connecting sleeve 20 abut against the limiting end face 41 of the handle 40, and also make the connecting sleeve 20 surround the locking member 30; then install the elastic reset member 70 into the connecting sleeve 20, and make one end of the elastic reset member 70 abut against the limiting block 22 of the connecting sleeve 20, and finally connect the limiting member 60 to the end of the mounting member 12 away from the fan blade 11, and make the limiting member 60 abut against the other end of the elastic reset member 70, thereby completing the assembly of the fan assembly 100.

[0114] In some embodiments, during the process of assembling the fan assembly 100, the user or worker may also assemble the fan assembly 100 upside down, for example, Fig. 9 The handle 40, the locking member 30 and the connecting sleeve 20 can be inverted and assembled into an integrated structure, and then the integrated structure is sleeved outside the mounting member 12 of the fan body and the locking member 30 is placed in the through hole 123, and finally the elastic reset member 70 and the limit member 60 are assembled in sequence.

[0115] The fan assembly 100 provided in any of the above embodiments of the present invention can be applied to the cooking appliance 1000 as well as other products requiring a detachable fan. For example, the fan assembly 100 can also be applied to an electric fan.

[0116] In the fan assembly 100 and the cooking utensil 1000 provided in the embodiment of the present invention, the mounting member 12 of the fan body 10 is provided with an axial hole 121 suitable for accommodating the driving shaft 201 of the driving device 200 in the axial direction, so that the driving shaft 201 of the driving device 200 can be inserted into the mounting member 12. The mounting member 12 is provided with a through hole 123 in the radial direction that is connected with the axial hole 121, and the locking member 30 is movably located in the through hole 123. The connecting sleeve 20 is movably sleeved on the mounting member 12 along the axial direction of the mounting member 12, and the connecting sleeve 20 drives the locking member 30 to abut against the driving shaft 201 to be in the locked position, so that the locking member 30 can lock the driving shaft 201 and the fan assembly 100; the connecting sleeve 20 provides the locking member 30 with a radial movement away from the driving shaft 201 to be in the unlocked position, so that the fan assembly 100 is easy to be disassembled from the driving shaft 201. In this way, the connecting sleeve 20 can switch between a locked position and an unlocked position through axial movement, so that the drive shaft 201 and the fan assembly 100 are easy to disassemble and assemble, thereby facilitating the removal of the fan assembly 100 from the drive shaft 201 for cleaning, which helps to simplify the cleaning operation and improves the problem of being unable to clean due to the inconvenience of using tools to disassemble and assemble in a small space. After cleaning, it also helps to quickly connect the fan assembly 100 to the drive shaft 201, making installation convenient, quick and efficient.
