[0020] Hereinafter, embodiments of the air intake grille structure of the air compressor of the present invention will be described with reference to the accompanying drawings.

[0021] Figure 1-5 The air intake grille structure of an air compressor of an embodiment of the utility model is shown, which includes a plurality of air intake holes 2 opened on the right side of the compressor body 1: a fixing frame 3 adapted to the plurality of air intake holes 2 is fixedly connected to the right side of the compressor body 1, a plug-in cavity 4 is opened at the top of the fixing frame 3 close to the compressor body 1, a filter body 5 is inserted into the inner cavity of the plug-in cavity 4, a locking component 6 is arranged between the filter body 5 and the fixing frame 3, and a rectangular hole 6 is opened at the top of one side of the locking component 6 1. The inner cavity of the rectangular hole 1 61 is installed with an elastic steel sheet 62, one side of the elastic steel sheet 62 penetrates to the outside of the filter body 5, and the top of one side of the fixed frame 3 is provided with a rectangular hole 2 64 adapted to the elastic steel sheet 62, and the inner cavity of the rectangular hole 2 64 is slidably connected with a pressing block 65, and both sides of the inner cavity of the rectangular hole 2 64 are provided with a limited slide groove 66, and both sides of the pressing block 65 are fixedly connected with a limited slider 67 sliding in the inner cavity of the limited slide groove 66, and one side of the elastic steel sheet 62 is welded with an arc The protrusion 63, the arc-shaped protrusion 63 abuts against one side of the pressing block 65, and through the cooperation of the limiting slider 67 and the limiting slide groove 66, the limiting slider 67 will be driven to slide in the inner cavity of the limiting slide groove 66 during the pressing of the pressing block 65, ensuring that the pressing block 65 will not be separated from the inner cavity of the rectangular hole 64, and after the pressing block 65 is pressed to the limit, the pressing block 65 abuts against the arc-shaped protrusion 63, so that the elastic steel sheet 62 is deformed and completely enters the inner cavity of the rectangular hole 61, and will not cause damage to the filter body 5. In order to affect the activities of the filter body 5, an elastic ejection component 7 is provided between the filter body 5 and the fixed frame 3. The elastic ejection component 7 includes strip blocks 71 welded to the tops of both ends of the filter body 5. The tops of both sides of the inner cavity of the plug-in cavity 4 are provided with strip grooves 72 for inserting the strip blocks 71. The bottom of the inner cavity of the strip groove 72 is provided with a circular hole 73. The bottom of the inner cavity of the circular hole 73 is fixedly connected with a spring 74. The top of the spring 74 is fixedly connected with a ejection block 75. The top of the ejection block 75 is against the bottom of the strip block 71.

[0022] Working principle: When the utility model is used, when the filter body 5 needs to be disassembled and cleaned, the pressing block 65 is pressed, so that the pressing block 65 squeezes the arc-shaped protrusion 63 to deform the elastic steel sheet 62 and detach from the inner cavity of the rectangular hole 64. At this time, the filter body 5 is released from the lock, and the springs 74 on both sides make the top block 75 press against the bottom of the strip block 71 due to the elastic force. The two strip blocks 71 drive the filter body 5 to move upward for a certain distance, so that the top of the filter body 5 protrudes to a part of the top of the fixed frame 3. Then the user pushes the filter body 5 upward to facilitate the removal of the filter body 5 from the inner cavity of the fixed frame 3 for cleaning. When installing, it is only necessary to pick up the filter body 5 and insert it into the inner cavity of the plug-in cavity 4 until the filter body 5 The elastic steel sheet 62 on the upper part is against the top of the fixed frame 3, and then the arc-shaped protrusion 63 is pressed to make the elastic steel sheet 62 enter the inner cavity of the rectangular hole 1 61, and then the filter body 5 is pressed downward. The elastic steel sheet 62 will not protrude from the inner cavity of the rectangular hole 1 61 due to the squeezing of the inner wall of the plug-in cavity 4. After the rectangular hole 1 61 is aligned with the rectangular hole 2 64, the elastic force of the elastic steel sheet 62 makes the elastic steel sheet 62 enter the inner cavity of the rectangular hole 2 64 to lock the filter body 5. During the downward movement of the filter body 5, the strip block 71 is driven to enter the inner cavity of the strip groove 72, and the strip block 71 squeezes the top block 75. The top block 75 moves toward the inner cavity of the circular hole 73 and squeezes the spring 74 to deform.

[0023] In summary, the air intake grille structure of the air compressor can be realized by pressing the pressing block 65, which is pressed against the arc-shaped protrusion 63, so that the elastic steel sheet 62 is deformed and disengaged from the inner cavity of the rectangular hole 64, and the filter body 5 is unlocked. The top of the filter body 5 is pushed out by the ejection block 75, so that the top of the filter body 5 protrudes to the top of the fixed frame 3, and then the filter body 5 is pushed upward to disengage from the inner cavity of the plug-in cavity 4. The user can clean the filter body 5, and the filter lock can be unlocked by pressing. The filter is partially ejected by the elastic component, which is convenient for taking out the filter for cleaning.
