Specifically, the housing 2 has an air inlet 21 and an air outlet 22. The electronic control box 1 is arranged on the shell 2, the electronic control box 1 comprises a box body 11, a cover body 12 and a circuit board 13, one side of the box body 11 along a first direction (for example, the up-down direction in fig. 1) is open, at least one first fixing buckle 111 is arranged on one side of the box body 11 along a second direction (for example, the left-right direction in fig. 1), at least one first elastic buckle 112 is arranged on the other side of the box body 11 along the second direction, and the second direction is perpendicular to the first direction. The cover 12 is disposed at one side of the case 11 along the first direction, and the cover 12 and the case 11 together define a receiving chamber 124. The circuit board 13 is disposed in the accommodating cavity 124, and the circuit board 13 is mounted in the accommodating cavity 124 by the first fixing buckle 111 and the first elastic buckle 112 to limit the movement of the circuit board 13 toward the cover 12.

For example, in the examples of fig. 1, 2, 3, 5 and 11, the air intake 21 is formed on the back surface of the housing 2, and the air outlet 22 is formed on the top of the housing 2. The electronic control box 1 is provided on the inner surface of the top wall of the housing 2, and three first fixing buckles 111 may be provided on the inner surface of the side wall of one side of the second direction of the box body 11, the three first fixing buckles 111 being spaced apart from each other along the length direction of the side wall. The inner surface of the side wall of the other side of the second direction of the case 11 may be provided with two first elastic buttons 112, and the two first elastic buttons 112 may be spaced apart from each other along the length direction of the side wall. The cover 12 is disposed on a side opposite to the open side of the case 11, and the cross-sectional area of the cover 12 is approximately equal to the cross-sectional area of the open side of the case 11, so that the cover 12 and the case 11 can cooperate to define the accommodating cavity 124, and the cover 12 can close the accommodating cavity 124, thereby protecting the components in the accommodating cavity 124. The area of the circuit board 13 is substantially equal to the area of the bottom surface of the case 11, and when the circuit board 13 is mounted in the accommodating chamber 124, the circuit board 13 is prevented from rocking or moving toward the cover 12 in the second direction in the accommodating chamber 124 due to the area of the circuit board 13 being smaller than the area of the bottom surface of the case 11.

When the circuit board 13 is installed, one end of the circuit board 13 in the second direction is firstly installed below the first fixing buckle 111, one side surface of the circuit board 13 is abutted against the bottom surface of the first fixing buckle 111, then the other end of the circuit board 13 in the second direction is pressed into the accommodating cavity 124 of the box body 11 after the first elastic buckle 112 is pressed, at the moment, the other end of the circuit board 13 is fixed by the first elastic buckle 112, one side surface of the circuit board 13 is abutted against the box body 11 of the circuit board 13 with the bottom surface of the first elastic buckle 112, and finally the cover body 12 is matched with the box body 11, so that the installation of the electric control box 1 is completed. When the circuit board 13 needs to be disassembled, the first elastic buckle 112 is pushed along the first elastic buckle 112 towards the side wall adjacent to the first elastic buckle 112, so that the first elastic buckle 112 is separated from the circuit board 13, and then the circuit board 13 is taken out from the box 11, so that the disassembly of the circuit board 13 is completed. Therefore, by arranging the first elastic buckle 112 and the first fixing buckle 111, on one hand, the first fixing buckle 111 and the first elastic buckle 112 can fix the circuit board 13, can limit the movement of the circuit board 13 towards the cover body 12, and ensures the stability of the position of the circuit board 13; on the other hand, the circuit board 13 is convenient to overhaul and replace, and the maintenance rate of operators is improved.
