[0071] Referring to FIG. 1, FIG. 2 and FIG. 3, FIG. 1 is a structural schematic diagram of the air fryer 10 of the present application. FIG. 2 is a side sectional view of the air fryer 10 shown in FIG. 1. FIG. 3 is a front sectional view of the air fryer 10 shown in FIG. 1.

[0072] The air fryer 10 provided by the present application comprises a body 100, a frying barrel 200, a first hot air assembly 300 and a second hot air assembly 400. The body 100 comprises an inner shell 110 and an outer shell 120. The inner shell 110 surrounds a cooking cavity 111 of the air fryer. The frying barrel 200 is arranged in the cooking cavity 111 and is used to accommodate food to be cooked. When the air fryer 10 is in operation, the food in the frying barrel 200 in the cooking cavity 111 is heated.

[0073] The outer side wall of the inner shell 110 and the inner side wall of the outer shell 120 surround an air duct 121 which surrounds the cooking cavity 111. When in operation, the hot air passes through the air duct 121 and can heat the cooking cavity 111 which is surrounded by the air duct 121, so that the temperature of the cooking cavity 111 is uniform. The inner shell 110 is provided with a ventilation opening 113 which is connected to the cooking cavity 111 and the air duct 121. The top of the inner shell 110 is provided with a reflecting cover 112. The ventilation opening 113 is arranged on the reflecting cover 112 along the axis direction of the air inlet 122.

[0074] In combination with FIG. 4, the bottom wall of the outer shell 120 is provided with an air inlet 122 which is connected between the air duct 121 and the external environment. In combination with FIG. 5, FIG. 5 is a schematic diagram of the internal air flow direction of the air fryer 10. The gas in the external environment enters the inner shell 110 and the outer shell 120 through the air inlet 122. The first hot air assembly 300 is arranged on the air inlet. The gas enters through the air inlet 122 and is heated under the action of the first hot air assembly 300, and then passes through the air duct 121. The second hot air assembly 400 is arranged on the reflecting cover 112. The gas in the air duct 121 enters the cooking cavity 111 through the ventilation opening 113 under the heating and driving of the second hot air assembly 400.

[0075] The barrel opening of the frying barrel 200 faces the ventilation opening 113. Therefore, when the frying barrel 200 is placed in the cooking cavity 111, the gas entering the cooking cavity 111 naturally enters the frying barrel 200 and heats the food in the frying barrel. In addition, the gas passes through the air duct 121 which surrounds the cooking cavity 111, so that the food can be heated while the temperature around the frying barrel 200 is stable and uniform, thereby improving the cooking effect.

[0076] In some embodiments, the outer shell 120 is further provided with a heat dissipation opening 124 which is connected between the air duct 121 and the external environment. The heat dissipation opening is arranged on the bottom wall of the outer shell 120, so that the body 100 close to the bottom wall of the outer shell 120 can be cooled, thereby reducing the risk of scalding when the user touches the outer shell 120.

[0077] Referring to FIG. 2 and FIG. 3, in combination with FIG. 6 and FIG. 7, the first hot air assembly 300 comprises a first fan 310 and a first heating element 320, which are arranged between the bottom walls of the inner shell 110 and the outer shell 120 along the axial direction of the air inlet 122, so as to heat the gas entering from the air inlet 122, and the heated gas enters the air duct 121 under the driving of the first fan 310, so as to maintain the temperature of the air duct 121 and keep the temperature around the fryer basket 200 uniform and stable. The first hot air assembly 300 further comprises a first driving element 311 connected to the first fan 310 for driving the first fan 310 to rotate.

[0078] In some embodiments, as shown in FIG. 7, the air fryer 10 further comprises a protective plate 330 arranged on the inner shell 110, the middle part of the protective plate 330 is provided with an opening, and the first heating element 320 is arranged at the middle opening position of the protective plate 330. The protective plate 330 serves as a carrier for the first heating plate 320, and the protective plate 330 is arranged around the first heating plate 320, which can be arranged between the inner shell 110 and the first heating element 320, and serves to protect the first heating plate 320 from burning the side wall of the inner shell 110 or even the side wall of the outer shell 120.

[0079] In some embodiments, as shown in FIG. 7, the air fryer 10 further comprises a heat insulation plate 340 arranged between the outer shell 120 and the inner shell 110, which serves to carry and install the first driving element 311 and the first fan 310. That is, the first driving element 311 and the first fan 310 are installed between the outer shell 120 and the inner shell 110 through the heat insulation plate 340. The first fan 310 is arranged on the upper side of the heat insulation plate 340, and the first driving element 311 is arranged on the lower side of the heat insulation plate 340.

[0080] In some embodiments, the heat insulation plate 340 comprises a wind guide structure arranged around the first driving element 311, which serves to guide the air flow drawn by the first fan 310 from the external environment to the air duct 121, so as to facilitate the air drawn by the first fan 310 to enter the air duct 121 along a predetermined route.

[0081] With reference to FIGS. 2 and 3, the second hot air assembly 400 is arranged on the reflector 112, and at least a part of the second hot air assembly 400 extends into the cooking cavity 111 through the air vent 113 in some embodiments. The second hot air assembly 400 is configured to heat the gas in the air duct 121 and draw the gas into the fryer basket 200. That is, when the first and second hot air assemblies are operated, the gas in the external environment can be heated and drawn into the air duct, and the gas in the air duct can be heated and drawn into the cooking cavity. It can be understood that the gas in the air duct 121 drawn into the fryer basket 200 by the second hot air assembly 400 has been heated by the first heating element 320, and thus the second hot air assembly 400 reheats the gas, which can shorten the heating time and improve the cooking efficiency.

[0082] The second hot air assembly 400 is arranged on the reflector 112 of the inner shell 110 by a support. In some embodiments, the second hot air assembly 400 includes a second fan 410 and a second heating element 420. The second fan 410 is arranged on the reflector 112 along the axis direction of the air inlet 122, and the second heating element 420 is arranged on the side of the second fan 410 away from the reflector 112. At least a part of the second fan 410 and the second heating element 420 extend into the cooking cavity 111 through the air vent 113. The second hot air assembly 400 further includes a second driving element 411 connected to the second fan 410 for driving the second fan 410 to rotate. The second driving element 411 and the second fan 410 are arranged on the reflector 112 of the inner shell 110 by a support.

[0083] The arrangement of the reflector 112 can improve the isolation effect between the air duct and the cooking cavity, so that the gas in the air duct can enter the cooking cavity after passing through the second fan 410 and the second heating element 420 as much as possible, thereby improving the heating effect of the second heating element 420 on the gas.

[0084] The air fryer 10 of the present application draws the gas in the air duct 121 into the cooking cavity 111 through the vent 113 by the second fan 410. The gas entering the cooking cavity 111 through the vent 113 passes through the second heating member 420 and is heated again. It can be understood that the first heating member 320 and the second heating member 420 can heat the cooking cavity 111 from above and below at the same time, and the fan arranged around the cooking cavity 111 can keep the temperature uniform around the cooking cavity 111, so that the cooking cavity 111 is heated from all sides and the temperature is uniform and stable. The food in the frying basket 200 is heated and cooked from all directions, so that the food does not need to be taken out to turn over during cooking, and the top, bottom and sides of the food can be cooked and crispy, improving the cooking convenience and effect. The gas heated by the second heating member 420 is the gas heated by the first heating member 320 and then drawn into the second heating member 420 from the air duct 121, which can shorten the heating time of the second heating member 420, improve the cooking efficiency and shorten the cooking time.

[0085] In some embodiments, the first heating member 320 is arranged as a heating plate including an electric heating sheet and a metal plate, so that the second heating member 420 has a large heating area, fast transmission efficiency and uniform heating. In some embodiments, the second heating member 420 is arranged as a heating tube. Since the gas heated by the second heating member 420 is the gas heated by the first heating member 320 and then drawn into the second heating member 420 from the air duct 121, the second heating member 420 arranged as a heating tube can save electricity while heating the gas to meet the cooking requirements. In some embodiments, the bottom wall of the inner shell 110 can be replaced by a heating plate, i.e. the inner shell 110 does not need to be provided with a bottom wall, to save materials and facilitate the miniaturization design of the air fryer 10. If the heated food residue falls, the plate-shaped structure of the heating plate is convenient for receiving the food residue and easy to clean.

[0086] Referring to FIGS. 2 and 3, the air fryer 10 includes at least one smoking box 130 for containing smoking materials to realize the smoking function of the air fryer 10 of the present application. The smoking box is arranged between the inner shell and the outer shell. In some embodiments, the smoking box 130 is arranged between the first fan 310 and the first heating member 320 along the axis direction of the air inlet 122, and the outer shell 120 is provided with a draw cavity for containing the smoking box 130. The smoking box 130 is arranged to be drawn out of the draw cavity through the outer shell 120 to replace the smoking materials in the smoking box 130.

[0087] The first heating member 320 is used to heat the smoking material of the smoking box 130. The smoking box 130 is provided with a smoke outlet for the smoke generated by the heating of the smoking material in the smoking box 130 to flow out, and the smoke outlet is communicated with the air duct 121. The smoking box 130 is arranged between the first fan 310 and the first heating member 320, or in other words, the smoking box is arranged at the bottom of the first heating member. The first heating member 320 can be used to heat the smoking material, and the first fan 310 can be used to bring the smoke generated by the heating of the smoking material into the air duct 121. The smoke enters the cooking cavity 111 along with the gas in the air duct 121 to smoke and cook the food in the frying barrel 200 in the cooking cavity 111. Without the need to arrange other structures to heat the smoking material, and without the need to arrange other structures to make the smoke generated by the heating of the smoking material enter the cooking cavity 111, the air fryer 10 of the present application can realize the smoking function while simplifying the structure of the air fryer 10, and facilitate the miniaturization design of the air fryer 10.

[0088] In some embodiments, the first heating member 320 is provided with a temperature sensor 321, and the air fryer comprises a controller electrically connected to the first heating member 320 and the temperature sensor 321. The temperature sensor 321 transmits the detected temperature information of the first heating member 320 to the controller. The controller is configured to adjust the heating power of the first heating member 320 and the air speed of the first fan according to the received temperature information or the temperature data detected by the temperature sensor 321 on the first heating member, so that the temperature in the smoking box 130 is within the range between the smoke generating point and the ignition point of the smoking material, to ensure that the smoking material only generates smoke and does not generate open flame, and to control the speed of the circulating smoke flow, thereby adjusting the smoking effect.

[0089] In some embodiments, the air fryer 10 comprises a display electrically connected to the controller. The display can be provided with selection keys for different smoking materials and selection keys for different food materials to be cooked. The selection keys are used to select the smoking function under different smoking materials and to select different food materials to be cooked. The controller controls the first heating member 320 to be at a corresponding temperature according to the selected different smoking materials and different food materials, so that the smoking function of different smoking materials and different food materials can be used normally, that is, the different smoking materials and different food materials can be temperature controlled to be at a suitable smoking temperature. In combination with the adjustable air outlet rate of the air outlet assembly 500, the air exhaust amount can be adjusted, which is beneficial to the retention of smoke in the cooking cavity 111, that is, the amount of smoke in the cooking cavity 111 is adjusted, so that the food materials in the frying barrel 200 can obtain better smoking effect and the smoking time can be accelerated. Part of the smoke is also exhausted from the air outlet assembly 500 to ensure that the cooking cavity 111 is in a stable state.

[0090] In some embodiments, the first heating element 320 is further provided with a temperature controller 322, which can be a snap-action temperature controller, to achieve over-temperature protection of the air fryer 10, i.e., when the temperature of the first heating element 320 reaches a preset value, the snap-action temperature controller is triggered to quickly cut off the power supply.

[0091] Referring to FIG. 8, the air fryer 10 further comprises an air outlet assembly 500 provided on the housing 120. The air outlet assembly 500 comprises an air outlet 540 which is in communication with the air vent 113 and the external environment, and an air outlet channel provided on the air outlet 540 to realize circulation of air inside and outside the air fryer 10 and adjust the stability of the air pressure inside and outside the air fryer 10.

[0092] In some embodiments, the air outlet assembly 500 is configured to adjust the size and / or direction of the air outlet channel, so as to adjust the size and / or direction of the air flow from the air outlet 540. By adjusting the flow rate of the air flow from the air outlet 540, the cooking time can be adjusted and the cooking effect can be changed. In some embodiments, the air fryer 10 of the present application comprises multiple cooking modes, and the flow rate of the air flow from the air outlet 540 can be adjusted by the air outlet assembly 500 according to different cooking modes. When flammable items are placed near the air fryer 10, the direction of the air flow from the air outlet 540 can also be changed to avoid the hot air flow from the air outlet 540 flowing onto the flammable items and causing the flammable items to burn and cause a fire.

[0093] In some embodiments, at least part of the air outlet 540 is located on the top side of the second fan 410. In combination with the fact that at least part of the second fan 410 is located inside the cooking cavity 111, it can be understood that most of the heated air blown from the air duct 121 enters the cooking cavity 111 under the action of the second fan 410, and part of the hot air that does not enter the cooking cavity 111 can be blown out from the air outlet 540 provided on the top side of the second fan 410, so as to avoid heating the inside of the housing 120 above the cooking cavity 111, which can cause overheating of this part and cause scalding hazards. That is, by locating the air outlet 540 on the top side of the second fan 410, the temperature of the air fryer 10 above the cooking cavity 111 can be reduced, and the risk of scalding can be reduced.

[0094] The air fryer 10 of the present application adopts bottom air inlet, and the gas entering the air inlet 122 on the bottom wall of the shell 120 is rapidly drawn into the air duct 121 after being heated by the first heating element 320, which can effectively reduce the temperature of the part below the cooking cavity 111 of the air fryer 10, and the first heating element 320 is arranged below the cooking cavity 111, which will not affect the heating of the cooking cavity 111. In combination with the arrangement of the air outlet 540, at least part of the air outlet 540 is located on the top side of the second fan 410, which can reduce the temperature of the part above the cooking cavity 111 of the air fryer 10. It can be seen that the arrangement of the air fryer 10 of the present application can ensure uniform cooking of food in the cooking cavity 111 while reducing the temperature of the part below and above the cooking cavity 111 of the air fryer 10, thereby reducing the risk of scalding.

[0095] In some embodiments, referring to FIGS. 9, 10 and 11, the air outlet assembly 500 includes a plurality of air deflectors 510 arranged at the air outlet 540, and the air outlet channel is defined between adjacent two air deflectors 510. The air deflectors 510 are configured to rotate in the same direction to adjust the size and / or direction of the air outlet channel.

[0096] The air outlet assembly 500 further includes adjusting members 520 respectively connected to the plurality of air deflectors 510. The adjusting members 520 are respectively connected to the plurality of air deflectors 510 and are configured to rotate the air deflectors 510 relative to the air outlet 540 to adjust the direction of the air deflectors 510 relative to the air outlet 540, or in other words, the inclination angle of the air deflectors 510 relative to the air outlet 540, thereby adjusting the size and / or direction of the air outlet channel between adjacent two air deflectors 510.

[0097] In some embodiments, each air deflector 510 is provided with a connecting shaft, and the end of the connecting shaft away from the air deflector 510 is rotatably connected to the side wall of the air outlet 540, so that the air deflector 510 can be rotated relative to the air outlet 540 by the rotating pin driven by the adjusting member 520, thereby adjusting the size and / or direction of the air outlet channel.

[0098] It can be understood that the plurality of air deflectors 510 are arranged side by side in sequence, and the adjusting members 520 simultaneously drive the plurality of air deflectors 510 to rotate. When rotated to the angle shown in FIG. 10, the surface of the air deflector 510 is parallel to the radial direction of the air outlet 540, at this time, the air outlet channel is the largest, the air outlet assembly 500 is in the maximum air outlet speed state, and the air outlet direction is parallel to the radial direction of the air outlet 540.

[0099] When rotated to the angle shown in FIG11 , the air outlet assembly 500 is at its minimum air outlet speed, i.e., the air outlet channel is at its smallest. At this point, two adjacent air guide plates 510 are partially stacked, with no gap between them, acting as windbreaks. At this point, the angle A between the surface of the air guide plates 510 and the radial direction of the air outlet 540 can be 75°. Angle A is determined by the spacing between adjacent air guide plates 510. The spacing between adjacent air guide plates 510 can be set during the manufacture of the air outlet assembly 500 to adjust the angle A between the surface of the air guide plates 510 and the radial direction of the air outlet 540 when the air outlet assembly 500 is at its minimum air outlet speed.

[0100] Continuing to refer to Figure 9, the air outlet assembly 500 includes an adjustment slot 521, which is obliquely arranged on the side top wall of the air outlet 540. The adjustment member 520 slides along the adjustment slot 521, thereby driving the multiple air guide plates 510 connected to the adjustment member 520 to rotate relative to the air outlet 540, thereby adjusting the size and / or direction of the air outlet channel, or realizing the adjustment of the air outlet rate and air outlet direction of the air outlet 540.

[0101] 8 and 9 , a sliding groove is provided on the housing 120, and the side of the adjustment member 520 away from the air guide plate 510 extends out of the housing 120 through the sliding groove, and the adjustment member 520 can move relative to the sliding groove so that the air guide plate 510 rotates relative to the air outlet 540, thereby adjusting the air outlet channel.

[0102] In some embodiments, the controller is electrically connected to the first hot air assembly 300 and the second hot air assembly 400 so as to be able to adjust the working power of the first fan 310, the first heating element 320, the second fan 410 and the second heating element 420 respectively, thereby putting the air fryer 10 in different working states, or making the air fryer 10 perform different functions.

[0103] In some embodiments, the air fryer 10 includes both smoking and steaming functions. When the smoking and steaming functions are not in use, the angle between the surface of the air guide plate 510 and the radial direction of the air outlet 540 can be adjusted to 0-25° for uniform steaming and baking. The angle between the surface of the air guide plate 510 and the radial direction of the air outlet 540 can be adjusted to 0° to accelerate exhaust, speed up the outflow of moisture from the food, and speed up cooking time. When the smoking and steaming functions are in use, the angle between the surface of the air guide plate 510 and the radial direction of the air outlet 540 can be adjusted to 75°, which can slow the discharge of smoke and water vapor entering the interior of the body 100, effectively shortening the smoking and steaming time of the ingredients and improving the smoking and steaming effect of the food.

[0104] In some embodiments, the air outlet assembly 500 can be configured as shown in FIGS. 12 and 13, which includes an air outlet rotating cover 530 arranged on the outer wall of the air outlet 540. The air outlet rotating cover 530 is provided with a plurality of air outlet holes with adjustable size or number, which are arranged in different directions of the air outlet rotating cover. By adjusting the rotation of the air outlet rotating cover 530 relative to the air outlet 540, the flow rate and direction of the airflow flowing out of the air outlet 540 can be changed.

[0105] Referring to FIGS. 13 and 14, in some embodiments, the air outlet rotating cover 530 includes an inner cover 531 and an outer cover 532 arranged on the inner cover 531. The inner cover 531 is provided with a plurality of first through holes 5311 in the radial direction of the air outlet 540 and a plurality of first side holes 5312 in the direction perpendicular to the radial direction of the air outlet. The outer cover 532 is provided with a plurality of second through holes 5321 in the radial direction of the air outlet 540 and a plurality of second side holes 5322 in the direction perpendicular to the radial direction of the air outlet. It can be understood that the first side holes 5312 and the second side holes 5322 correspond to each other, the first through holes 5311 and the second through holes 5321 correspond to each other, and the outer cover 532 is arranged to be able to rotate relative to the inner cover 531 in the direction parallel to the axial direction of the first through holes 5311, so that the first through holes 5311 and the second through holes 5321 can be aligned or offset with each other, or the first side holes 5312 and the second side holes 5322 can be aligned or offset with each other.

[0106] By rotating the outer cover 532 relative to the inner cover 531, the number of the first through holes 5311 and the second through holes 5321 aligned with each other, or the number of the second through holes 5321 capable of air outlet, can be adjusted, and the number of the first side holes 5312 and the second side holes 5322 aligned with each other can be adjusted to adjust the number of the second side holes 5322 capable of air outlet, thereby adjusting the air exhaust capacity of the air outlet 540. And by controlling the first through holes 5311 and the second through holes 5321 not to be aligned, while the first side holes 5312 and the second side holes 5322 are aligned with each other, the air outlet direction can be adjusted.

[0107] Referring to FIGS. 2, 3, 15 and 16, the air fryer 10 further includes a water tank arranged on the outer shell 120 and an atomizing assembly 600 arranged in the water tank to realize the above-mentioned steaming and baking functions of the air fryer 10. The outer shell 120 is provided with a recess on one side close to the top wall, and a detachable cover is further arranged on the recess. The cover is arranged on the recess, and the atomizing assembly 600 is arranged in the cavity formed between the recess and the cover.

[0108] The atomization assembly 600 comprises an atomization pipe 610 having an atomization outlet arranged towards the second fan 410. The atomization assembly 600 generates atomization mist which flows from the atomization outlet to the second fan 410 through the atomization pipe 610, and the atomization mist is drawn into the cooking cavity 111 under the driving of the second fan 410. It can be understood that the second fan 410 draws the air in the air duct 121 into the cooking cavity 111, and at the same time, the second fan 410 also brings the atomization mist flowing from the atomization outlet into the cooking cavity 111, so as to steam and roast the food in the cooking cavity 111. In this way, an additional suction device is not needed to draw the atomization mist generated by the atomization assembly 600 into the cooking cavity 111, thereby saving the cost of the air fryer and facilitating the miniaturization design.

[0109] The atomization assembly 600 comprises a water tank 620 arranged on the housing 120 and an atomization structure 630 arranged in the water tank 620. The top wall of the water tank 620 is provided with a water inlet, so as to add water into the water tank 620 from the water inlet, for the atomization structure 630 to generate atomization mist according to the water in the water tank 620.

[0110] The atomization structure 630 comprises an atomization sheet 631 capable of receiving the liquid in the water tank 620, and a mist guide cylinder 632 having two open ends. The first end of the mist guide cylinder 632 is communicated with the atomization pipe 610, and the second end of the mist guide cylinder 632 is arranged towards the atomization sheet 631, or in other words, the mist guide cylinder 632 is capable of being communicated between the atomization pipe 610 and the atomization sheet 631. The atomization mist generated by the atomization sheet 631 can flow to the atomization pipe 610 through the mist guide cylinder 632. That is, the atomization sheet 631 contacts the water in the water tank 620 to generate atomization mist, and the atomization mist flows into the cooking cavity 111 through the mist guide cylinder 632 and the atomization pipe 610 in sequence.

[0111] In some embodiments, the first end of the mist guide cylinder 632 is close to the top wall of the water tank 620, and the atomization pipe 610 is arranged on the side wall of the water tank 620 close to the top wall of the water tank 620, so that the water mist guided by the mist guide cylinder 632 flows from the upper side of the inside of the water tank 620 to the atomization pipe 610, and then flows from the atomization outlet of the atomization pipe 610 to the cooking cavity 111. Arranging the relative positions of the mist guide cylinder 632 and the atomization pipe 610 close to the top wall of the water tank 620 can avoid the water in the water tank 620 directly entering the atomization sheet 631 from the mist guide cylinder 632, and facilitate the water control unit 634 to control the water flow into the atomization sheet 631.

[0112] Referring to FIGS. 17 and 18, the atomization structure 630 further comprises an atomization base 633 and a water control unit 634. The atomization base 633 is arranged outside the water tank 620, and the water tank 620 comprises a first side wall. The atomization base 633 and the first side wall define a containing cavity in communication with the mist guide cylinder 632. The water control unit 634 and the atomization sheet 631 are arranged in the containing cavity. The water control unit 634 is configured to control whether the water in the water tank 620 can enter the atomization sheet 631.

[0113] The first side wall is provided with a water inlet hole 6322 in communication with the containing cavity. The water control unit 634 comprises a water control switch configured to close or open the water inlet hole 6322 to control whether the water in the water tank 620 enters the containing cavity, thereby controlling whether the atomization sheet 631 generates water mist.

[0114] In some embodiments, as shown in FIG. 18, the water control switch comprises a water control float 6341 and a float spring 6342. The water control float 6341 is arranged in the containing cavity and abuts the first side wall along the axis direction of the water inlet hole 6322 and blocks the water inlet hole 6322. When the water control float 6341 blocks the water inlet hole 6322, the water in the water tank 620 cannot enter the containing cavity, and the atomization sheet 631 does not generate water mist. The float spring 6342 is connected between the side of the water control float 6341 away from the first side wall and the second port of the mist guide cylinder 632 along the axis direction of the water inlet hole 6322 to provide elastic force to the water control float 6341, so that the water control float 6341 can abut the water inlet hole 6322 on the first side wall.

[0115] The atomization structure further comprises a water inlet portion 6324. The water inlet portion 6324 and the first side wall define a water separation sub-cavity. The water inlet hole 6322 is in communication with the water separation sub-cavity. The water inlet portion 6324 is provided with a water control hole 6323. The radial dimension of the water control hole 6323 is smaller than the radial dimension of the water inlet hole 6322. The water control hole 6323 is configured to adjust the size of the water flow entering the atomization sheet 631 from the water inlet hole 6322.

[0116] In some embodiments, the mist guide cylinder 632 comprises a cylinder body 6321 and the above-mentioned water inlet portion 6324. One end of the cylinder body 6321 is provided with the first port, and the other end is provided with the second port. The water inlet portion 6324 surrounds the second port. Along the axis direction of the water inlet hole 6322, the float spring 6342 is connected between the side of the water control float 6341 away from the first side wall and the water inlet portion 6324 to provide elastic force to the water control float 6341 towards the first side wall.

[0117] In some embodiments, the hole diameter d1 of the water control hole 6323 and the hole diameter d2 of the water inlet hole 6322 satisfy: 0.5mm≤d1≤1.5mm, 4mm≤d2, respectively. The water inlet portion 6324 is arranged in the accommodating cavity and separates the accommodating cavity into the water-proof sub-cavity and an atomizing piece sub-cavity. The water control float 6341 and the float spring 6342 are arranged in the water-proof sub-cavity, and the atomizing piece 631 is arranged in the atomizing piece sub-cavity. In combination with the radial size of the water control hole 6323 being smaller than the radial size of the water inlet hole 6322, it can be known that, after water is filled in the water tank 620, if the pressure of the water in the water tank 620 on the water control float 6341 through the water inlet hole 6322 is greater than the elastic force of the float spring 6342 on the water control float 6341, the water control float 6341 moves towards the float spring 6342, the water inlet hole 6322 is opened, and the water in the water tank 620 enters the water-proof sub-cavity through the water inlet hole 6322.

[0118] The water in the water-proof sub-cavity provides the water control float 6341 with buoyancy, and as the water in the water-proof sub-cavity increases, the buoyancy on the water control float 6341 increases. When the buoyancy on the water control float 6341 and the elastic force of the float spring 6342 on the water control float 6341 are greater than the pressure of the water in the water tank 620 on the water control float 6341 through the water inlet hole 6322, the water control float 6341 moves towards the water inlet hole 6322 until the water inlet hole 6322 is blocked. The water in the water-proof cavity slowly enters the atomizing piece sub-cavity through the water control hole 6323, so that the atomizing piece 631 in the atomizing piece sub-cavity contacts water to generate mist, the second port of the mist guide cylinder 632 is communicated with the atomizing piece sub-cavity, and the mist is conducted to the mist outlet pipe 610 through the mist guide cylinder 632.

[0119] When the water in the water-proof sub-cavity enters the atomizing piece sub-cavity through the water control hole 6323 until the buoyancy of the water in the water-proof sub-cavity on the water control float 6341 and the elastic force of the float spring 6342 on the water control float 6341 are less than the pressure of the water in the water tank 620 on the water control float 6341 through the water inlet hole 6322, the water control float 6341 again moves towards the float spring 6342, the water inlet hole 6322 is opened, and the water in the water tank 620 enters the water-proof sub-cavity through the water inlet hole 6322, so that the water-proof sub-cavity stores water. It can be understood that, as the water in the water-proof sub-cavity again increases to the above, the water control float 6341 moves towards the water inlet hole 6322 until the water inlet hole 6322 is blocked when the buoyancy on the water control float 6341 and the elastic force of the float spring 6342 on the water control float 6341 are greater than the pressure of the water in the water tank 620 on the water control float 6341 through the water inlet hole 6322, and the water in the water-proof cavity again enters the atomizing piece sub-cavity through the water control hole 6323……, so that the water in the water tank 620 can stably and slowly flow into the atomizing piece sub-cavity, improve the stability and persistence of the atomizing piece 631 in generating water mist, and improve the atomizing effect.

[0120] Referring to FIG. 15 and FIG. 17, the atomization assembly 600 further comprises a partition plate 623, the water tank 620 has an inner cavity, the partition plate 623 is arranged in the inner cavity and divides the inner cavity into a water storage sub-cavity 621 and a buffer sub-cavity 622, the water inlet hole 6322 is communicated with the water storage sub-cavity 621, and the end of the mist outlet pipe 610 away from the mist outlet is communicated with the buffer sub-cavity 622. The buffer sub-cavity 622 is used to accommodate the water mist generated by the atomization sheet 631, so as to avoid that the generated water mist directly and rapidly flows into the cooking cavity 111, causing that the water mist in the cooking cavity 111 is too much, the temperature is reduced, the cooking time is increased, and the cooking effect is reduced.

[0121] The upper top wall of the water tank 620 is provided with a water inlet 640 for adding water into the water tank 620 through the water inlet 640. The water inlet 640 is arranged on the side close to the water storage sub-cavity 621. It can be understood that if the user adds too much water at one time, the partition plate 623 and the upper top wall of the water tank 620 are provided with a preset interval, so that too much water can enter the buffer sub-cavity 622 from the preset interval, avoiding that the water overflows into the fryer to cause a short circuit of the circuit.

[0122] In some embodiments, as shown in FIG. 16, the water tank 620 is provided with a water amount detector 624, the controller is electrically connected to the water amount detector 624 and the display respectively, the water amount detector 624 is used to detect the water amount in the water tank 620, and the controller is used to control the display to display the water amount in the water tank 620 detected by the water amount detector 624. In some embodiments, the water amount detector 624 is arranged as a pressure sensor, the pressure sensor is arranged outside the water tank 620 and on the bottom wall of the water tank 620, and the amount of water in the water tank 620 is fed back by checking the pressure of the water tank 620 to prompt the user to add water.

[0123] The mist outlet pipe 610 comprises a pipe body 611, a valve bead 6121 and an elastic member 6122, the elastic member 6122 is connected between the pipe body 611 and the valve bead 6121, and the valve bead 6121 can block the pipe body 611 under the elastic pressure of the elastic member 6122. It can be understood that the valve bead 6121 and the elastic member 6122 form a one-way valve 612 arranged on the pipe body 611, and the one-way valve 612 comprising the valve bead 6121 and the elastic member 6122 is arranged on the end of the mist outlet pipe 610 close to the water tank 620, the water mist can only enter from the end of the mist outlet pipe 610 close to the water tank 620 and flow out from the mist outlet by controlling the one-way valve 612, the mist in the cooking cavity 111 can be blocked from flowing back into the water tank 620, effectively avoiding that the heat in the cooking cavity 111 flows back into the water tank 620, causing that the temperature of the water tank 620 is too high, and reducing the service life of the atomization structure 630.

[0124] As shown in Figure 19, the one-way valve 612 also includes a valve seat 6123 and a valve cover 6126 which are arranged in sequence in the radial direction of the mist outlet pipe 610. The valve cover 6126 is close to the side of the water tank 620. A first valve opening 6124 is opened on the valve seat 6123 along the radial direction of the mist outlet pipe 610, and a second valve opening 6125 is opened on the valve cover 6126 along the radial direction of the mist outlet pipe 610.

[0125] In some embodiments, the valve cover 6126 and the valve seat 6123 are threadedly connected, and the valve ball 6121 and the elastic member 6122 are arranged between the valve cover 6126 and the valve seat 6123. One end of the elastic member 6122 is connected to the valve seat 6123, and the other end is connected to the elastic member 6122. The valve ball 6121 faces the second valve port 6125 of the valve cover 6126, and under the elastic force of the elastic member 6122, it can abut against the second valve port 6125 to block the second valve port 6125, thereby making the one-way valve 6122 in a closed state.

[0126] In other words, the water mist in the water tank 620 enters the mist outlet pipe 610 and flows from the second valve port 6125 to the first valve port 6124. When the second fan 410 is running, the air is sucked out to put the mist outlet pipe 610 in a negative pressure state, causing the valve ball 6121 to move toward the elastic member 6122, thereby opening the second valve port 6125. The water mist flows in the mist outlet pipe 610 from the end close to the water tank 620 toward the mist outlet, and smoothly passes through the second valve port 6125 and the first valve port 6124 to flow to the mist outlet, thereby realizing the steaming and baking function.

[0127] When the second fan 410 is not running to generate negative pressure, the valve ball 6121 is blocked in the second valve port 6125 by the elastic member 6122, so that the mist outlet pipe 610 is in a closed state. The hot air in the cooking chamber 111 cannot pass through the mist outlet pipe 610 into the water tank 620, thereby preventing the hot air in the cooking chamber 111 from flowing back into the water tank 620, causing the water temperature to be too high, and causing the atomization structure 630 to fail to work.

[0128] It can be understood that the outer walls of the valve seat 6123 and the valve cover 6126 are interference fit connected with the inner wall of the mist outlet pipe 610, so that the mist in the mist outlet pipe 610 can only flow through the first valve port 6124 and the second valve port 6125, thereby realizing the one-way valve 612's control over the one-way conduction of the mist outlet pipe 610.

[0129] In some embodiments, the mist outlet is provided with a nozzle 650, which effectively controls the discharge amount of water mist, avoids excessive use of water due to too much water mist, and avoids excessive use of water in the water tank 620. The mist outlet is sprayed towards the second fan 410 through the nozzle 650, and the sprayed water mist is sucked into the cooking cavity 111 through the negative pressure generated by the second fan 410 and heated by the second heating element 420, which quickly vaporizes and accelerates the process of mist becoming steam after heating, effectively shortening the steam baking time. In combination with the adjustable air exhaust structure of the air outlet assembly 500, the water mist stays in the cavity, which is beneficial to the better steaming and baking effect of the food in the frying barrel 200.

[0130] The air fryer 10 also has a self-cleaning and disinfecting function. When there is no food in the frying barrel 200, the atomization function is used, and the air outlet assembly 500 is adjusted to maximize the air outlet amount of the air outlet 540. During the operation of the air fryer 10, the water mist quickly becomes steam after being heated by the second heating element 420. When the cold and hot air and steam in the cooking cavity 111 are in a stable circulation state, the steam can perform high-temperature cleaning and disinfection on the internal parts of the air fryer 10, effectively realizing the function of self-cleaning and disinfection.

[0131] Referring to FIGS. 1 and 2, the frying barrel 200 includes a barrel body 210 disposed in the cooking cavity 111 and a handle 220 connected to the barrel body 210 and penetrating the inner shell 110 and the outer shell 120, so as to facilitate holding the frying barrel 200 by the handle 220. The frying barrel 200 also includes a front cover disposed on the barrel body 210 and connected to the handle. It can be understood that one side of the body 100 of the air fryer 10 is provided with an opening for the barrel body 210 of the frying barrel 200 to extend into the cooking cavity 111. When the barrel body 210 is located in the cooking cavity 111, the front cover is located at the opening, and the handle is located outside the body 100. By holding the handle, the barrel body 210 can be brought in or out of the cooking cavity 111, realizing the placing and taking of food materials.

[0132] In some embodiments, the frying barrel 200 also includes a heat insulation block 230 disposed between the barrel body 210 and the front cover, which plays a heat insulation role to avoid overheating of the front cover, thereby avoiding scalding of the user when holding the handle 220.

[0133] In some embodiments, the frying barrel 200 also includes a baking tray 240 for supporting food materials, which includes a tray body and a bottom frame disposed at the bottom of the tray body.
