The shape and the size of the air outlet hole can be specifically set according to actual conditions so as to better meet actual application.
In some embodiments of the present invention, as shown in fig. 7 and 9, the positioning protrusion 21 extends along the height direction of the switch door 2, so that the positioning protrusion 21 may be approximately formed into a long strip shape, and two ends of the positioning protrusion 21 may extend toward the upper and lower ends of the switch door 2, so that the positioning protrusion 21 has a simple structure and is convenient to implement, and meanwhile, due to the long length of the positioning protrusion 21, it is ensured that the positioning protrusion 21 may extend into the positioning slot 11 when the switch door 2 closes the air outlet 10, so as to avoid the situation that the positioning protrusion 21 and the positioning slot 11 are staggered up and down and cannot be matched due to the movement of the switch door 2. Here, the "height direction" refers to the up-down direction.
In some alternative embodiments of the present invention, the height of the positioning protrusion 21 is the same as the height of the switch door 2, the upper end surface of the positioning protrusion 21 may be flush with the upper end surface of the switch door 2, and the lower end surface of the positioning protrusion 21 may be flush with the lower end surface of the switch door 2, at this time, the height of the positioning protrusion 21 is greater, so that the positioning protrusion 21 has sufficient strength, and the reliability of the cooperation between the positioning protrusion 21 and the positioning slot 11 is ensured.
In other alternative embodiments of the present invention, the height of the positioning protrusion 21 is smaller than the height of the opening and closing door 2, that is, at least one of the upper end and the lower end of the positioning protrusion 21 does not extend to the end face of the opening and closing door 2, so that the amount of material of the positioning protrusion 21 is saved and the cost is reduced while the strength of the positioning protrusion 21 is ensured. For example, when only the upper end of the positioning projection 21 does not extend to the upper end face of the switch door 2, the lower end face of the positioning projection 21 may be flush with the lower end face of the switch door 2, and the upper end face of the positioning projection 21 is located below the upper end face of the switch door 2; when only the lower end of the positioning protrusion 21 does not extend to the lower end face of the switch door 2, the upper end face of the positioning protrusion 21 may be flush with the upper end face of the switch door 2, and the lower end face of the positioning protrusion 21 is located above the lower end face of the switch door 2; when both the upper and lower ends of the positioning protrusion 21 do not extend to the end face of the switch door 2, the upper end face of the positioning protrusion 21 may be located below the upper end face of the switch door 2, and the lower end face of the positioning protrusion 21 may be located above the lower end face of the switch door 2.
Optionally, an assembling bump 13 is provided on the inner side of the face frame 1, and a groove extending along the height direction of the face frame 1 is provided on the assembling bump 13 to form a positioning groove 11. For example, as shown in fig. 3 to 6, 12 and 13, the fitting projection 13 may extend in the height direction of the face frame 1, the positioning groove 11 may be concavely formed by a part of the outer surface of the fitting projection 13, and the positioning groove 11 may penetrate through the upper end surface and the lower end surface of the fitting projection 13 in the height direction of the face frame 1 so that both the upper and lower ends of the positioning groove 11 are opened. Thus, by providing the fitting projection 13 on the inner side of the face frame 1 and forming the positioning groove 11 on the fitting projection 13, the structure of the face frame 1 can be simplified, and the processing of the face frame 1 can be facilitated.
Wherein, the assembling lug 13 can be integrally formed with the face frame 1, so as to ensure the connection reliability between the assembling lug 13 and the face frame 1; the assembly lugs 13 may also be separately formed from the face frame 1, and then the assembly lugs 13 are fixedly connected to the inner side of the face frame 1.
