DETAILED DESCRIPTION

[0027] The specific implementation modes of the present invention will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.

[0028] The present invention adopts this micro-motor assembly fixing structure, such as Figures 1 to 8 As shown in the figure, a mounting seat 4 is provided on the air inlet housing 1, a mounting slot 45 is provided on the mounting seat 4, and a mounting buckle 25 correspondingly installed in the mounting slot 45 is provided on the micromotor 2. The mounting seat 4 is installed by plugging the buckle, which is convenient for installation and arrangement and reduces production costs.

[0029] In the present invention, Figure 4 As shown in the figure, the mounting seat 4 is a U-shaped structure with one side open. The mounting buckle 25 and the mounting slot 45 are arranged at the front end of the micromotor mounting direction. The three sides of the U-shaped structure of the mounting seat 4 are provided with a shell assembly surface, and the three side walls of the micromotor 2 corresponding to the mounting seat 4 are provided with a micromotor assembly surface that matches the shell assembly surface.

[0030] In the present invention, the micromotor assembly surface is a convex block structure protruding from the side wall of the micromotor, and the upper end surface of the micromotor assembly surface is in contact with the lower end surface of the housing assembly surface. In an embodiment provided by the present invention, a micromotor first assembly surface 21, a micromotor second assembly surface 22 and a micromotor third assembly surface 26 are provided on both sides of the micromotor 2, and a housing first assembly surface 41, a housing second assembly surface 42 and a housing third assembly surface 46 are provided at corresponding positions of the mounting seat 4.

[0031] In the present invention, the mounting seat 4 and the side wall of the micromotor 2 are respectively provided with a housing limit platform and a micromotor limit platform which are arranged correspondingly to limit the front and rear position of the micromotor 2. The mounting seat 4 is provided with a first housing limit platform 43 and a second housing limit platform 44 on both sides, and the micromotor 2 is provided with a first micromotor limit platform 23 and a second micromotor limit platform 24 on both sides. During the micromotor insertion process, the contact surface between the first housing limit platform 43 and the first micromotor limit platform 23 is a guide sliding surface with a certain slope, and the contact surface between the second housing limit platform 44 and the second micromotor limit platform 34 is also a guide sliding surface with a certain slope.

When inserting, the elasticity of the plastic part is used. The first micromotor limit platform 23 and the second micromotor limit platform 24 on both sides of the micromotor pass through the first shell limit platform 43 and the second shell limit platform 44 of the air inlet housing. After assembly, the front and rear limit is realized, as shown in FIG. Figure 6 , 7 The three micro-motor assembly surfaces of the micro-motor 2 and the housing assembly surface on the air inlet housing are in surface-to-surface contact to prevent the micro-motor from moving, as shown in FIG.
