By arranging the piston assembly 27 capable of opening and closing the sealing port 232 at the sealing port 232, when the water tank 20 is mounted, the water outlet nozzle 31 can drive the piston assembly 27 to move upward to open the sealing port 232 to realize normal water supply, and when the water tank 20 is detached, the piston assembly 27 moves downward to close the sealing port 232 to avoid the water in the water tank 20 flowing out from the water outlet 22 under the siphon effect to pollute the external environment, thereby effectively improving the user experience; at the same time, by arranging the filter assembly 26 matched with the water flow channel 25 in the water flow channel 25, not only can the impurities in the water be blocked and filtered to ensure the hygiene and edible safety of the water supply of the water tank 20, effectively ensuring the user experience, but also can avoid the impurities in the water from blocking and / or damaging the infusion system 30 to ensure the performance stability and use safety of the air fryer.

[0028] As Figure 2 and Figure 3As shown, in an optional embodiment, one end of the water flow channel 25 is connected to the water outlet channel 231 through the sealing port 232, and the other end is adapted to extend to the bottom of the inner cavity 21 and communicate with the inner cavity 21. This arrangement allows the water in the inner cavity 21 to flow out more effectively through the water flow channel 25, thus avoiding the situation where there is water in the water tank 20 but it cannot supply water normally, effectively ensuring the water supply stability of the water tank 20 and the performance stability of the air fryer.

[0029] like Figure 2 and Figure 3 As shown, in an optional embodiment, the filter assembly 26 includes a filter screen 261 with through holes, the periphery of which is adapted to abut against the inner wall of the water flow channel 25. By abutting the periphery of the filter screen 261 against the inner wall of the water flow channel 25, better filtration of the water flowing out of the water tank 20 through the water flow channel 25 can be achieved, thereby ensuring the hygiene and food safety of the water supplied by the water tank 20.

[0030] like Figure 2 and Figure 3 As shown, in an optional embodiment, the piston assembly 27 includes a piston member 271. A first sealing member 272, made of an elastic material such as rubber or silicone, is fitted onto the piston member 271 to match the sealing port 232. The piston member 271 is adapted to seal with the sealing port 232 through the first sealing member 272. The first sealing member 272 allows the piston member 27 to better engage with the sealing port 232, ensuring the sealing stability and sealing effect of the sealing port 232.

Positioning the first sealing member 272 through the sealing groove 273 can effectively reduce the installation difficulty of the first sealing member 272, and reduce the production cost and user cost of the air fryer. At the same time, the sealing groove 273 is also adapted to limit the installation of the first sealing member 272. Limiting the installation of the first sealing member 272 through the sealing groove 273 can prevent the first sealing member 272 from sliding freely, thus avoiding a poor seal and effectively ensuring the sealing stability and sealing effect of the first sealing member 272.

[0032] like Figure 2 and Figure 3As shown, in an optional embodiment, the first seal 272 has a sealing lip 274 extending obliquely outward toward the top of the piston 271 at its periphery, and the sealing opening 232 has a sealing chamfer 233 matching the sealing lip 274 at its periphery.

[0033] like Figure 2 and Figure 3 As shown, in an optional embodiment, the piston 271 has a downwardly extending push rod 275 at its bottom. When the water tank 20 is installed in the mounting groove, the push rod 275 is adapted to abut against the water outlet 31. By providing the downwardly extending push rod 275 at the bottom of the piston 271, not only can the travel distance of the water outlet 31 and the piston 271 be shortened, reducing the time required for the piston 271 to close the sealing port 232, but it can also prevent the water outlet 31 from directly abutting against the piston 271, thereby avoiding damage to the piston 271 and resulting in a poor seal. This effectively ensures the performance stability and sealing stability of the piston 271.

[0034] like Figure 2 and Figure 3 As shown, in an optional embodiment, a vertically extending guide groove 276 is provided on the outer side of the top rod 275. When the top rod 275 abuts against the water outlet 31, the guide groove 276 is adapted to connect the water outlet 31 and the water outlet channel 22. By providing the guide groove 276 on the outer side of the top rod 275, the blockage of the water outlet 31 when the top rod 275 abuts against the water outlet 31 can be avoided, thereby affecting the normal water supply of the water tank 20, and effectively ensuring the water supply stability and performance stability of the water tank 20.

By arranging the second sealing element 32 sealingly cooperating with the water outlet nozzle 31 and the periphery of the mounting hole 13 below the mounting hole 13, external liquid can be prevented from entering the machine body 10 from the mounting hole 13, thereby avoiding damage to electrical devices such as the driving system and control circuit in the machine body 10, and effectively ensuring the performance stability and use safety of the air fryer.

[0036] As shown in the figure, Figure 2 and Figure 3 Figure 2 Figure 3 As shown in the figure, in an optional embodiment, the two side walls of the mounting groove 12 and the two side walls of the water tank 20 are provided with guide structures 40, the guide structures 40 include vertically extending guide portions 41 arranged on the two side walls of the mounting groove 12 and guide grooves 42 arranged on the two side walls of the water tank 20 corresponding to the guide portions 41, and when the guide portions 41 are aligned with the openings of the guide grooves 42, the water tank 20 can move towards the bottom of the mounting groove 12. By arranging the guide portions 41 and the guide grooves 42 on the two side walls of the mounting groove 12 and the water tank 20 respectively, not only can the installation of the water tank 20 be guided, effectively reducing the installation difficulty of the water tank 20 and improving the user convenience, but also can the water tank 20 be limited to reduce the damage of the water tank 20 due to sliding and falling, effectively improving the performance stability of the air fryer and the user experience.
