An intake passage 11 is provided at the bottom of the suction port body 1, and a suction port 3 is provided at the upper part. An exhaust passage 31 is provided in the suction port 3. The cooling unit 2 is detachably provided inside the suction port body 1, and the inside is hollow to form a cooling air passage 21. The cooling air passage 21 communicates with the intake passage 11 and the exhaust passage 31 respectively, and a plurality of partition plates 22 are provided inside, and the cooling air passage 21 is a multi-layer air passage with a meandering shape.

[0008] As shown in FIGS. 1 and 3, after the present suction port structure is attached to the heating type tobacco device, during use, the hot air flow flows from the intake passage 11 at the bottom into the cooling air passage 21, and flows through the meandering cooling air passage 21 to the exhaust passage 31 of the suction port 3. Since a plurality of partition plates 22 are provided in the cooling air passage 21, the cooling air passage 21 is a multi-layer air passage with a meandering shape, the flow path of the hot air flow is effectively extended, the temperature of the hot air flow gradually decreases, a cooling effect is obtained, and the suction port 3 can be prevented from getting hot. Furthermore, the cooling unit 2 is detachable, and subsequent cleaning is easy.

As the right part of the filter member 4, a filter mesh is provided. When the filter member 4 is mounted on the first mounting port, the filter mesh is inserted into the cooling air passage 21 and is in close contact with the left end of the partition plate 22.

[0011] That is, by providing the partition plate 22, the cooling air passage 21 becomes a two-layer air passage, and in the process of the air flow flowing from the bottom air passage to the upper air passage, it passes through the filter mesh on the left side and is filtered and dispersed. Such a structure is simple and easy to implement. Furthermore, a first seal ring 5 is provided between the filter member 4 and the cooling unit 2, which exhibits a good sealing effect. In actual manufacturing and processing, the suction port 3 and the cooling unit 2 are made of ceramic material, the filter member 4 is made of stainless steel material, and its surface is gold-plated. These materials are healthy and pure, and by using these materials, the air flow generated by the heated tobacco device can provide a better flavor for the user after passing through the cooling unit 2 and the suction port 3.
