[0026] The present invention will now be described in detail with reference to specific embodiments.

[0027] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a tea cabinet with dual-circulation air ducts for uniform temperature and humidity includes a cabinet body 1, an inner liner 2, a first air duct 3, a left sealed air duct 4, and a right sealed air duct 5. The inner liner is located inside the cabinet. The first air duct is located at the rear of the inner liner, with its air inlet 31 connected to the lower part of the inner liner and its air outlet 32 ​​connected to the upper part of the inner liner. A circulating fan is installed inside the first air duct. The left sealed air duct 4 and the right sealed air duct 5 are located inside the first air duct 3. This structure is compact and saves cabinet space. The left sealed air duct is located in the left half of the cabinet body, and the right sealed air duct is located in the right half of the cabinet body. The air inlet 41 of the left sealed air duct is connected to the lower part of the inner liner, and the air outlet 42 of the left sealed air duct is connected to the middle part of the inner liner. The air inlet 51 of the right sealed air duct is connected to the lower part of the inner liner, and the air outlet 52 of the right sealed air duct is connected to the middle part of the inner liner. The left sealed air duct is equipped with a left blower 43 to allow air circulation, and the right sealed air duct is equipped with a right blower 53 to allow air circulation.

[0028] The inner liner decorative panel 6 is located at the inner rear part of the inner liner, and the first air duct is formed by the inner liner decorative panel and the corresponding inner liner wall at the inner rear part of the inner liner. This structure is compact.

[0029] The left air duct 7 is tightly attached to the inner wall of the inner liner decorative panel, and the left sealing air duct is composed of the left air duct 7 and the inner liner decorative panel 6. This structure is easy to assemble and has a simple structure.

[0030] The right air duct 8 is tightly attached to the inner wall of the inner liner decorative panel, and the right sealing air duct is composed of the right air duct 8 and the inner liner decorative panel 6. This structure is easy to assemble and has a simple structure.

[0031] Working principle: During operation, the airflow inside the inner liner circulates through three main independent airflow channels: the first air duct, the left sealed air duct, and the right sealed air duct. This ensures sufficient airflow circulation in the upper, lower, left, and right spaces within the inner liner, resulting in uniform and stable temperature and humidity. This avoids the problem of uneven and unstable temperature and humidity throughout the inner liner of tall and wide cabinets.

[0032] Example 2: The characteristic of this example is that, Figure 5 , Figure 6 , Figure 7 As shown, the left sealed air duct 4 has a left branch air duct on the side closest to the right sealed air duct.
