[0021] See also Figure 1-4 The utility model provides a technical solution: a circulating fan with a guide device, comprising a fan body 1, an air inlet 2, an air outlet 3, a guide plate 4 and an air outlet plate 5, a reinforcement ring 6 is fixedly sleeved on the air outlet 3, a mounting frame 7 inserted into the air outlet 3 is fixedly provided on the air outlet plate 5, a card slot 8 is symmetrically provided on the side wall of the mounting frame 7, a card block slot 10 is correspondingly provided on the inner wall of the air outlet 3 and extends into the reinforcement ring 6, a card block 9 for clamping into the card slot 8 and limiting the mounting frame 7 is provided in the card block slot 10, a pressure plate slot 14 connected to the card block slot 10 is symmetrically provided on the outer wall of the reinforcement ring 6, and a pressure plate 15 for preventing the card block 9 from sliding out of the card slot 8 is provided in the pressure plate slot 14.

[0022] Specifically, a clamping block groove 11 is symmetrically provided on the inner wall of the clamping block groove 10, and a clamping spring 12 is fixedly provided on the inner wall of the clamping block groove 11 near the pressure plate groove 14. The clamping spring 12 is fixedly connected to a clamping block 13. The clamping block 13 is slidably arranged in the clamping block groove 11 and is fixedly connected to the side wall of the clamping block 9. Under the elastic force of the clamping spring 12, the clamping block 9 can be clamped into the clamping groove 8 to limit the installation frame 7.

[0023] Specifically, one end of the clamping block 9 located in the air outlet 3 is an arc surface and fits tightly with the clamping groove 8, which is convenient for the disassembly and assembly of the air outlet plate 5. When the air outlet plate 5 is not installed, the clamping block 13 is against the inner wall of the clamping block groove 11 under the elastic force of the clamping spring 12, and the arc surface end of the clamping block 9 is located in the air outlet 3. The other end of the clamping block 9 is flush with the bottom of the pressure plate groove 14 and is attached to the pressure plate 15. When installing the air outlet plate 5, the pressure plate 15 is slid away from the clamping block groove 10 to make the clamping block 9 lose its limit, and the installation frame 7 is inserted into the air outlet 3. The arc surface end of the clamping block 9 and the side wall of the installation frame 7 act to make the clamping block 9 slide out of the air outlet 3 and drive the clamping block 1 3 compresses the clamping spring 12 until the air outlet plate 5 abuts against the end surface of the air outlet 3. At this time, the clamping block 9 is opposite to the clamping slot 8. Under the elastic force of the clamping spring 12, the clamping block 9 is clamped into the clamping slot 8 to limit the installation frame 7. The pressing plate 15 slides to the clamping block slot 10 and fits with one end of the clamping block 9 to limit the clamping block 9, ensuring the stability of the installation of the installation frame 7. When disassembling, slide the pressing plate 15 away from the clamping block slot 10, so that the clamping block 9 loses its limit, and the air outlet plate 5 is pulled out with force. The arc surface of the clamping block 9 slides out of the air outlet 3 due to the force of the inner wall of the clamping slot 8, so that the installation frame 7 loses its limit and slides out of the air outlet 3, completing the disassembly of the air outlet plate 5.

[0024] Specifically, a clamping spring 16 is fixedly provided on the inner wall of the pressure plate groove 14 away from the block groove 10 . The clamping spring 16 is fixedly connected to the side wall of the pressure plate 15 . The elastic force of the clamping spring 16 causes the pressure plate 15 to be located on the block groove 10 .

[0025] Specifically, a stabilizing rod 17 is fixedly provided on the inner wall of the pressure plate groove 14, and the stabilizing rod 17 passes through the pressure plate 15 and is slidably connected to the pressure plate 15. The stabilizing rod 17 is limited to ensure that the pressure plate 15 can always fit the bottom of the pressure plate groove 14, that is, it can fit the block 9 tightly to prevent the block 9 from sliding out of the slot 8 and making the air outlet plate 5 unstable. The clamping spring 16 is sleeved on the stabilizing rod 17 to ensure that the elastic direction of the clamping spring 16 remains in the axial direction, so as to exert the best elastic effect of the clamping spring 16.

[0026] Specifically, a protrusion 18 is fixedly provided on the pressing plate 15, and the protrusion 18 facilitates pushing the pressing plate 15. One end of the installation frame 7 located in the air outlet 3 is an inclined surface to prevent the installation frame 7 from generating a large resistance to exhaust.

[0027] A specific application example of this embodiment is:

[0028] When the device is in use and the air outlet plate 5 needs to be disassembled, the protrusion 18 is pushed to drive the pressure plate 15 to slide so that the pressure plate 15 slides away from the block groove 10 so that the block 9 loses its limit, the air outlet plate 5 is pulled out with force, and the arc surface of the block 9 slides out of the air outlet 3 under the force of the inner wall of the groove 8, so that the installation frame 7 loses its limit and slides out of the air outlet 3, completing the disassembly of the air outlet plate 5, and the air outlet plate 5 is convenient to clean. After the cleaning is completed, the air outlet plate 5 can be installed again, and the pressure plate 15 is slid away from the block groove 10 so that the block 9 loses its limit, and the pressure plate 15 is compressed to press the spring 16, and the installation frame 7 is inserted into the air outlet The arc end of the card block 9 and the side wall of the installation frame 7 act to make the card block 9 slide out of the air outlet 3 and drive the clamping block 13 to compress the clamping spring 12 until the air outlet plate 5 abuts against the end face of the air outlet 3. At this time, the card block 9 is opposite to the clamping groove 8. Under the elastic force of the clamping spring 12, the card block 9 is clamped into the clamping groove 8 to limit the installation frame 7. The pressure plate 15 is released. Under the elastic force of the clamping spring 16, the pressure plate 15 slides to the card block groove 10 and fits with one end of the card block 9 to limit the card block 9, thereby ensuring the stability of the installation of the installation frame 7. The installation of the air outlet plate 5 can be completed, and the operation is convenient.
