The first guide portion 41 is a grid-like structure, and the connecting portion 43 is a groove structure. The setting of the air guide curved surface 431 can weaken the impact of the airflow on the connecting portion 43, reduce the vibration of the air guide component 40 under the impact of the airflow, and further reduce the noise emitted by the vibration of the air guide component 40, so that the ventilation efficiency of the air guide component 40 is higher.

[0056] Specifically, the second guide portion 42 is in a bent structure, and one side of the second guide portion 42 away from the cold air cover 21 along the third direction is farther away from the first guide portion 41 than the other side in the first direction.

[0057] Specifically, the second guide portion 42 is used to block the airflow flowing out of the air outlet opening 12, and the connecting portion 43 is placed on the side of the second guide portion 42 away from the cold air hood 21 along the third direction, so that the direction of the airflow can be turned from along the second direction toward the direction of the adjacent air guide component 40 to along the third direction toward the adjacent cold air hood 21, thereby preventing the user at the air outlet opening 12 from being scalded by the airflow.

[0058] Specifically, a plurality of convex strips are provided on a side of the second guide portion 42 away from the first guide portion 41 , and the plurality of convex strips are evenly spaced along the first direction. The convex strips are used to increase the heat dissipation area of ​​the second guide portion 42 , thereby improving the heat dissipation performance of the air guide assembly 40 .

[0059] In application, the first guide portion 41 is provided with a plurality of first fixing portions along the circumferential direction, and the inner circumferential wall of the housing 10 is provided with a plurality of second fixing portions corresponding to the plurality of first fixing portions one by one, and the first fixing portions are engaged and connected with the second fixing portions.

[0060] Specifically, the first fixing portion and the second fixing portion are hooks and buckles with each other, a portion of the multiple first fixing portions is arranged on one side of the first guide portion 41 along the third direction, and another portion of the multiple first fixing portions is arranged on the other side of the first guide portion 41 along the third direction, so that the air guide assembly 40 can be installed at the air outlet opening 12 of the shell 10 along the third direction.
