Thus, the exemplary term "above" can include both "above" and "below" orientations. The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein are interpreted accordingly.

[0030] In addition, it needs to be explained that the use of "first", "second" and the like to limit parts is only for the convenience of distinguishing the corresponding parts, and the above words have no special meaning if there is no further declaration, and therefore cannot be understood as limiting the protection scope of the utility model.

[0031] For reference Figures 1-10 As shown in the figure, a circulating fan is provided with a microphone 1, the circulating fan is provided with a mounting portion, the mounting portion comprises a mounting cavity 2, the microphone 1 is arranged in the mounting cavity 2, the mounting cavity 2 comprises a bottom surface 3, the bottom surface 3 is provided with an annular limiting rib 4; the microphone 1 is provided with an annular protrusion 5, and the annular protrusion 5 is in interference fit with the annular limiting rib 4.

[0032] As Figure 8 and Figure 10 shown, by arranging the annular limiting rib 4 on the bottom surface 3 of the mounting cavity 2, the annular protrusion 5 on the microphone 1 is in interference fit with the annular limiting rib 4, which avoids the shaking of the microphone 1 in the mounting cavity 2, and further avoids the change of the position of the microphone 1 during the assembly process and the moving process, improves the stability of the fixation of the microphone 1 in the mounting cavity 2, avoids the unnecessary gap between the microphone 1 and the mounting cavity 2, the two structures of the annular structure are in interference fit with each other, the balance and stability of the force between the microphone 1 and the bottom surface 3 are ensured, the microphone 1 is prevented from being locally raised to form a gap, and further the phenomenon of inaccurate sound collection caused by the transmission of sound in the unnecessary gap is avoided. The accuracy of the sound pickup of the microphone 1 is improved, and the user experience is improved.

[0033] Preferably, the annular protrusion 5 is a rubber ring.

[0034] The annular protrusion 5 is a rubber ring, the rubber ring has a certain flexibility, and the rubber ring has a damping effect on the microphone 1 during the movement of the circulating fan, and the stability of the interference connection between the microphone 1 and the annular limiting rib 4 is improved.

[0035] Further, the annular limiting rib 4 is also a rubber ring.

[0036] Preferably, the annular protrusion 5 is arranged on the inner side or the outer side of the annular limiting rib 4.

[0037] The annular protrusion 5 is arranged on the inner side or the outer side of the annular limiting rib 4, and the convenience of the installation of the microphone 1 is improved.

[0038] Preferably, as Figure 8 shown, the mounting portion comprises a stop rib 6, the stop rib 6 is opposite to the bottom surface 3 of the mounting cavity 2, the microphone 1 is arranged between the bottom surface 3 and the stop rib 6, and the stop rib 6 abuts against the microphone 1.

[0039] In the prior art, there is a certain gap between the stop rib 6 and the microphone 1, and the gap size is greater than or equal to 0.5 mm. This makes the microphone 1 have a phenomenon of being tilted up during assembly, which makes the microphone 1 and the bottom surface 3 of the mounting cavity 2 cannot be effectively attached and form a certain gap. The gap forms an entrance effect, and the sound is reflected and scattered in the gap, resulting in speech recognition failure of the microphone 1. The present application avoids the phenomenon of the microphone 1 being tilted up by making the stop rib 6 abut the microphone 1. By providing the stop rib 6, the microphone 1 is arranged between the bottom surface 3 of the mounting cavity 2 and the stop rib 6. The stop rib 6 presses the microphone 1 to fix the microphone 1 in the mounting cavity 2. In this way, the microphone 1 is firmly fixed in the depth direction of the mounting cavity 2, which avoids the phenomenon of the microphone 1 being tilted up, and makes the microphone 1 have a complete and stable sound pickup cavity. That is, the microphone 1 and the bottom surface 3 of the mounting cavity 2 will not have unnecessary gaps due to the tilting or shaking of the microphone 1 itself, thereby improving the accuracy of sound pickup of the microphone 1.

[0040] In addition, the microphone 1 structure of the existing voice function circulating fan mostly adopts glue fixing. In the production process, this scheme has low operation efficiency, and the glue fixing position of the microphone 1 is limited. The glue gun cannot be accurately aimed at the glue fixing point, the glue fixing amount cannot be well controlled, and there is a glue overflow phenomenon, which affects subsequent assembly, causes poor overall assembly consistency, and requires reinstallation for repair; the present application fixes the microphone 1 by mutual clamping of the annular protrusion 5 and the annular rib, and presses the microphone 1 in the mounting cavity 2 by the stop rib 6, thereby eliminating the need for glue fixing, improving assembly efficiency, improving the consistency of the position of the microphone 1 in the mounting cavity 2, and reducing the repair rate.

[0041] Preferably, as shown in Figure 8 and Figure 9 , the side of the stop rib 6 facing the microphone 1 is provided with a boss 7, and the side of the microphone 1 facing the stop rib 6 is provided with a groove 8, and the boss 7 is clamped into the groove 8.

[0042] By clamping the boss 7 into the groove 8, the stability of the microphone 1 fixed by the stop rib 6 is improved. Further, the boss 7 abuts the bottom wall of the groove 8. Preferably, the outer surface of the boss 7 is a circular arc surface.

[0043] Preferably, as shown in Figure 8 , the bottom surface 3 of the mounting cavity 2 is provided with a sound collecting hole 9, and the sound collecting part of the microphone 1 is opposite to the sound collecting hole 9.

[0044] The sound collecting part of the microphone 1 is opposite to the sound collecting hole 9, which facilitates the sound entering the microphone 1 and improves the accuracy of sound pickup of the microphone 1.

[0045] Preferably, as shown in Figure 8As shown, the sound receiving part of the microphone 1 is attached to the bottom surface 3 of the mounting cavity 2.

[0046] The sound receiving part is attached to the bottom surface 3 of the mounting cavity 2 (here, the attachment refers to that the annular protrusion 5 of the sound receiving part is in contact with the bottom surface 3), which ensures that the sound from the sound hole 9 can only enter the sound receiving part of the microphone 1, and ensures the accuracy of the sound pickup of the microphone 1.

[0047] Preferably, as shown in Figure 1 , Figure 2 , Figure 5 and Figure 6 , the side wall of the mounting cavity 2 is provided with a notch 10, and the lead wire 11 of the microphone 1 is arranged in the notch 10.

[0048] By arranging the lead wire 11 of the microphone 1 in the notch 10 of the side wall, unnecessary extrusion of the lead wire 11 of the microphone 1 is avoided, and the safety of the microphone 1 is ensured.

[0049] The overall assembly process of the microphone 1 is as follows: first, place the microphone 1 in the mounting cavity 2 of the body support; then insert the body support into the corresponding position of the upper pipe (a component of the circulating fan), and then fix it through two screws.
