Of course, in actual application, water can also be directly stored in steam cavity 11 and heated to evaporate in steam cavity 11.

[0030] As shown, Figure 3 The top of host computer 1 is placed with several steamers 2 stacked in sequence, and top cover 3 is capped on the top layer steamer 2. In this way, the user can choose how many steamers 2 to place according to the needs. As shown, Figure 2 And Figure 3 Each steamer 2 is equipped with cooking function chamber 21 for placing food and upper and lower steam flow-through chamber 22. When the steamers 2 are stacked, the steam flow-through chambers 22 are communicated and form a steam passage. When the steamer 2 is placed on the top of host computer 1, the steam passage is communicated with steam cavity 11. The steamer 2 is equipped with air inlet passage 23 between cooking function chamber 21 and steam flow-through chamber 22, and valve device 24 capable of shielding or opening air inlet passage 23. In this way, hot steam enters steam passage from steam cavity 11, and steam in steam flow-through chamber 22 enters cooking function chamber 21 through air inlet passage 23. Each layer of steamer 2 can adjust the opening or closing degree of air inlet passage 23 through valve device 24, so as to control whether steam enters and the amount of steam of each layer of steamer 2. Therefore, different layers of steamers 2 can be suitable for cooking different foods, and the air inlet passage 23 of part of the layers of steamers 2 can be selectively closed in different time periods of cooking, so as to better control the cooking time of each layer and prevent the mixture and flavoring of different layers of steamers 2.

[0031] As a preferred option, such as Figure 6 and Figure 7 As shown, the steamer 2 has a partition 25 between the cooking chamber 21 and the steam circulation chamber 22. The valve device 24 includes a mounting base 241 connected to the partition 25, and an air inlet channel 23 is opened on the mounting base 241. A rotating component 242, which is sealed at one end of the air inlet channel 23, is rotatably connected to the mounting base 241. The rotating component 242 has an adjustment hole 243 that can communicate with the air inlet channel 23 after rotating to a preset angle. This structure is simple and compact, ensuring reliable opening and closing of the air inlet channel 23.

[0032] To facilitate user operation, the rotating component 242 is connected to a knob 244 located on the outer wall of the steamer 2 for manual operation. Simply turning the knob 244 controls the opening and closing of the valve device 24. Preferably, as... Figure 4 and Figure 7 As shown, the knob 244 includes a rotating disk 245 and a pointer 246 connected to the rotating disk 245 and extending outward. The outer wall of the steamer 2 has a first protrusion 201 and a second protrusion 202 located on the rotation path of the pointer 246 and capable of blocking its rotation. When the pointer 246 rotates to the top of the first protrusion 201, the adjusting hole 243 is aligned with the air intake channel 23; when the pointer 246 rotates to the top of the second protrusion 202, the adjusting hole 243 is misaligned with the air intake channel 23; and when the pointer 246 rotates to the middle position between the first protrusion 201 and the second protrusion 202, the adjusting hole 243 is partially misaligned with the air intake channel 23, making the air intake diameter of the air intake channel 23 smaller, thereby controlling the air intake volume. The rotation range of the pointer 246 between the first protrusion 201 and the second protrusion 202 determines the aforementioned preset angle, which is typically set between 80° and 120°.

[0033] To improve structural stability, the mounting base 241 has a groove 247 at one end of the air intake channel 23 for accommodating the rotating component 242. The rotating component 242 is cylindrical and partially embedded in the groove 247. The groove wall of the groove 247 matches the shape of the rotating component 242, and the cross-section of the adjusting hole 243 matches the cross-sectional shape of the air intake channel 23. On the one hand, the cylindrical surface of the rotating component 242 fits tightly against the groove wall of the groove 247, improving airtightness; on the other hand, the cylindrical rotating component 242 rotates more smoothly in conjunction with the groove 247, improving structural stability.

[0034] As a further optimization, such as Figure 7 As shown, a rotating rod 248 is connected between the knob 244 and the rotating part 242. A rotating shaft hole 203 is provided on the side wall of the steamer 2 for the rotating rod 248 to extend outward.

[0035] As a preferred option, such as Figure 4 As shown, the steamer 2 includes a base 26 and a steamer frame 27 covering the base 26. The base 26 and the steamer frame 27 together form a steaming chamber 21, improving ease of use. As a further preferred embodiment, such as... Figure 2 and Figure 5 As shown, the side walls of the steaming chamber 21 gradually slope inward from top to bottom, resulting in a larger opening at the top and a smaller opening at the bottom. The base 26 has a first step 261 for engaging with the upper cage frame 27 and a second step 262 for engaging with the lower cage frame 27. Between the first step 261 and the second step 262, the base 26 has an exhaust vent 263 for venting steam from the lower steamer. This allows the steaming chamber 21 of the lower steamer 2 to connect with the exhaust vent 263, enabling steam from the lower steamer 2 to escape through the exhaust vent 263 and preventing excessive pressure. This structure ensures that steam from each layer is exhausted independently, without needing to pass through the upper steamer 2, further guaranteeing the independence of steam usage for each layer.

[0036] As a preferred option, such as Figure 4 As shown, the base 26 includes a base plate 264 made of metal and a handle 265 made of plastic attached to one side of the base plate 264. This ensures good thermal conductivity of the base plate 264 while preventing heat from being quickly conducted to the handle 265, thus avoiding burns to the user's hands.
