Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1 As shown, the heat dissipation structure of this air compressor includes a housing 1. One side of the housing 1 has a cylindrical mounting part with an inner hole for mounting. The cooling fan 3 of the air compressor is located inside the housing 1 and is directly opposite the mounting hole.

[0020] like Figure 4 As shown, the air compressor's heat dissipation structure also includes a circular, flat fan shroud 2, with several through holes 2a, each a hexagonal hole. The outer side of the outer casing 1 has several protruding, block-shaped locking blocks 1b, distributed around the mounting opening 1a. The fan shroud 2 covers the mounting opening 1a, and its outer edge has several buckles 2b protruding vertically towards the outer casing 1. The number of buckles 2b is the same as the number of locking blocks 1b, and they are engaged in a one-to-one correspondence. In this embodiment, the side of the latch 1b facing the fan cover 2 has an inclined guide surface 1d that facilitates the latch 2b to be fastened to the outside of the latch 1b. That is, the thickness of the latch 1b in the radial direction of the fan cover 2 gradually decreases from the end away from the fan cover 2 to the end closer to the fan cover 2. The outer edge of the fan cover 2 has a group of radially outward protruding block-shaped reinforcing parts 2d. The number of groups of reinforcing parts 2d is the same as the number of latches 2b and they are arranged one-to-one. Each group of reinforcing parts 2d consists of two adjacent and spaced reinforcing parts 2d. The latch 2b is U-shaped and its opening faces the fan cover 2. The two ends of the latch 2b are connected to the two reinforcing parts 2d in each group of reinforcing parts 2d. The width of the reinforcing part 2d in the circumferential direction of the fan cover 2 is greater than the width of the two ends of the latch 2b in the circumferential direction of the fan cover 2.

[0021] A limiting port 1c is horizontally opened on the upper side of the mounting port 1a on the outer casing 1, and the bottom of the limiting port 1c is connected to the top of the mounting port 1a. The fan cover 2 has a corresponding limiting part 2c that protrudes towards the limiting port 1c and is inserted into the limiting port 1c.

[0022] like Figure 2 and Figure 3 As shown, the limiting part 2c includes a vertically arranged plate 2e in the shape of a flat plate. Both sides of the plate 2e have block-shaped abutment parts 2f that protrude into the limiting opening 1c, and the two abutment parts 2f abut against the side walls opposite to the limiting opening 1c respectively.

[0023] When the fan cover 2 in the heat dissipation structure of the air compressor is installed, the limiting part 2c of the fan cover 2 is correspondingly clamped into the limiting opening 1c of the shell 1 to orient and limit the circumference of the fan cover 2, and then the several buckles 2b on the outer edge of the fan cover 2 are correspondingly deformed outward along the guide surface 1d of the clamping block 1b and then reset inward to be buckled on the outer side of the clamping block 1b, so as to fix the fan cover 2. When disassembled, the buckle 2b is pushed outward, so that the buckle 2b is disengaged from the clamping block 1b, and then the fan cover 2 is pulled outward, so that the fan cover 2 is disengaged from the shell 1, and the disassembly is convenient.

[0024] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
