In an embodiment, when the air outlet portion 121 is in the first distribution manner, the air outlet portion 121 includes a plurality of air outlets distributed at intervals, and each air outlet is a designated air outlet 1216.

In one embodiment, the mouthpiece 12 includes a plurality of spaced apart vents 120; when the air outlet portion 121 is in the first distribution mode, the air vent 120 is a generic term of the air inlet 1221 and the air outlet; when the air outlet 121 is in the second or third distribution mode, the air vent 120 is collectively referred to as an air inlet 1221, a first air outlet 1213, and a second air outlet 1214.

Specifically, as shown in fig. 18, the vent 120 includes an outer vent section 1201 and an inner vent section 1202 connected and communicating with each other in the airflow flowing direction of the vent 120; the ventilation surface of the outer tuyere section 1201 means a cross section of the outer tuyere section 1201 perpendicular to the airflow flowing direction of the ventilation opening 120; the ventilation surface of the inner tuyere section 1202 means a cross section of the inner tuyere section 1202 perpendicular to the airflow flowing direction of the ventilation opening 120.

The first housing 10 is typically manufactured by injection molding, and the vent 120 is formed as an outer vent section 1201 and an inner vent section 1202, and the outer vent section 1201 and the inner vent section 1202 can be formed by injection molding. At a given length of the vent, the use of the outer and inner mold sections to collectively form the vent 120 allows for easier and more convenient demolding of the outer and inner mold sections than the use of an integral injection molding to form the vent.

Further, the ventilation face of the outer tuyere section 1201 is smaller than the ventilation face of the inner tuyere section 1202; in this way, the housing assembly 100 can be prevented from being over-penetrated so as to hide the internal structure in the housing assembly 100, and also to increase the aesthetic appearance of the skin treatment device; in addition, the ventilation surface of the inner tuyere section 1202 is made larger, which is also advantageous for demolding of the inner mold section.

Further, the length of the outer tuyere section 1201 is smaller than the length of the inner tuyere section 1202, and the length direction of the outer tuyere section 1201 and the length direction of the inner tuyere section 1202 are the same as the airflow flowing direction of the ventilation opening 120; i.e., the length of the inner tuyere section 1202 having a large ventilation surface is made longer while hiding the inner structure in the housing assembly 100, the ventilation amount of the ventilation opening 120 can be made not too small, i.e., a large ventilation amount of the ventilation opening 120 is ensured.

Further, in the direction from the inner tuyere section 1202 to the outer tuyere section 1201, the ventilation surface of the outer tuyere section 1201 is gradually increased so that the outer tuyere section 1201 is flared; thus, the demolding of the outer mold section is facilitated.

Under the condition that the air port arrangement area is limited, the area of the air inlet area is smaller than that of the first air outlet area, namely, the area of the first air outlet area is larger, so that the speed of the air outlet airflow (heat dissipation airflow) with larger wind resistance in the shell assembly 100 is improved, and the heat dissipation efficiency is improved.
