In addition, the skilled in the art can combine and combine the different embodiments or examples described in the present application and the features of different embodiments or examples without contradiction.

[0038] According to the ion fan of the present application, please refer to Figure 1 and Figure 2 , comprising a cover 100, a fan blade 200 and an ion generator 400. The cover 100 is formed with a cavity inside, the fan blade 200 and the ion generator 400 are installed in the cavity, and the cover 100 is provided with a window 300 corresponding to the ion generator 400 for identifying the ion generator 400.

[0039] According to the embodiment of the present application, since the window 300 is directly arranged on the outer cover 100, the user can perceive the ion purification function of the ion generator 400 through the window 300, which is more intuitive and can enable the user to intuitively perceive whether the current fan is equipped with the ion generator 400. Moreover, since the position of the window 300 corresponds to the ion generator 400, the user can directly confirm the specific installation position of the ion generator 400 in the cavity through the window 300, which can facilitate the user to maintain, replace, etc. the ion generator 400 during use.

[0040] According to the embodiment of the present application, the window 300 is provided with at least one of color identification, text identification and pattern identification. When the window 300 is provided with color identification, the color of the window 300 can be distinguished from the color of other areas of the outer cover 100, so that the user can intuitively see the position of the window 300. For example, if the outer cover 100 is silver in color as a whole, the window 300 can be gray to be distinguished from other positions of the outer cover 100. When the window 300 is provided with text identification, the window 300 can be formed by etching, painting, etc. Chinese, English or other text to represent "ion generator", which can be referred to as Figure 3 and Figure 4 When the window is provided with pattern identification, the pattern representing "ion generator" can also be formed by etching, painting, etc. Of course, the window 300 can also be provided with at least two of color identification, text identification and pattern identification at the same time.

[0041] In the embodiment of the present application, the window 300 can also not be provided with identification, but a visible window is adopted, so that the user can observe the ion generator 400 through the visible window to achieve the effect of presenting the ion generator 400. The visible window can adopt a transparent cover plate, so that the user can see the ion generator 400 inside the outer cover 100 through the transparent cover plate.

[0042] Please refer to Figure 2According to the embodiments of the present application, the ion generator 400 is located at the outer periphery of the fan blade 200. In this case, the fan blade 200 does not shield the ion generator 400 from any direction, and thus the ion generator 400 can directly correspond to the window 300 on the outer cover 100 from any direction, and the ion generator 400 and the outer cover 100 are not separated by other components (e.g., the fan blade 200). When the window 300 is transparent, the window 300 is arranged on the front side, the rear side, or the peripheral side of the outer cover 100, and the user can see the ion generator 400 through the window 300. The case where the ion generator 400 is located at the outer periphery of the fan blade 200 includes a case where the ion generator 400 and the tip of the fan blade 200 are spaced apart along the radial direction of the fan blade 200, or a case where the ion generator 400 and the tip of the fan blade 200 partially overlap along the radial direction of the fan blade 200, in which case part of the ion generator 400 is shielded by the fan blade 200 and the other part is exposed outside the fan blade 200. Of course, the ion generator 400 and the fan blade 200 can also have other positional relationships, for example, the ion generator 400 can be arranged on the rear side of the fan blade 200, as long as the window 300 can be arranged on the outer cover 100 to correspond to the ion generator 400.

[0043] When the ion generator 400 and the tip of the fan blade 200 are spaced apart along the radial direction of the fan blade 200, the ion generator 400 does not interfere with the fan blade 200 regardless of the position of the ion generator 400 along the axial direction of the fan blade 200. The spacing between the ion generator 400 and the tip of the fan blade 200 can be, but is not limited to, 3-50 mm, so as to ensure that the fan blade 200 and the ion generator 400 do not interfere with each other while ensuring compact structure. When the ion generator 400 and the tip of the fan blade 200 partially overlap along the radial direction of the fan blade 200, the ion generator 400 needs to be misaligned with the fan blade 200 along the axial direction of the fan blade 200 to avoid interference between the fan blade 200 and the ion generator 400. Please refer to Figure 2 The ion generator 400 is misaligned with the fan blade 200 along the axial direction of the fan blade 200.

[0044] According to the embodiments of the present application, in combination with Figure 1 The outer cover 100 includes a front mesh cover 110, an outer shell 130, and a rear mesh cover 120, and a cavity is formed between the front mesh cover 110, the outer shell 130, and the rear mesh cover 120, and the window 300 is arranged on the front mesh cover 110. Since the user is generally located on the front side of the ion fan, the window 300 is arranged on the front mesh cover 110, which can be more convenient for the user to see. Of course, the position of the window 300 is not limited by the examples herein, for example, the window 300 can also be arranged on the side wall of the outer shell 130 and the rear mesh cover 120. Corresponding Figure 2The position of the ion generator 400, it is obvious that the window 300 can be arranged on the front net cover 110, the side wall of the shell 130, and the rear net cover 120. And it needs to be pointed out that, corresponding Figure 2 The position of the ion generator 400, the window 300 can also be distributed on two or three of the front net cover 110, the rear net cover 120 and the shell 130. If the ion generator 400 is arranged on the rear side of the fan blade 200, and the ion generator 400 is blocked by the fan blade 200 when viewed from the front side, the window 300 is arranged on at least one of the rear net cover 120 and the shell 130. If the ion generator 400 is arranged on the front side of the fan blade 200, and the ion generator 400 is blocked by the fan blade 200 when viewed from the rear side, the window 300 is arranged on at least one of the front net cover 110 and the shell 130.

[0045] When the ion generator 400 is arranged on the front side of the fan blade 200, the generated ions can be prevented from contacting the fan blade 200, the rear net cover 120 or the shell 130, etc., to avoid reducing the ion purification effect, and under the driving of the airflow, the generated ions are more easily diffused into the surrounding air, improving the purification effect.

[0046] According to the embodiments of the present application, please refer to Figure 3 When the ion fan is a floor fan, at this time, the ion fan includes the base 30, the support mechanism 20 and the fan head 10, the fan head 10 includes the outer cover 100, the fan blade 200 and the ion generator 400 mentioned above. Further, in combination with Figure 1 The inner side wall of the rear net cover 120 is provided with a motor support 121, and the ion generator 400 is fixed to the motor support 121. In this case, no additional fixing component of the ion generator 400 is needed, only the ion generator 400 is directly fixed on the motor support 121, so that the motor support 121 meets the fixing requirements of the rotating motor 500 and the ion generator 400. The rotating motor 500 here is different from the main motor for driving the fan blade 200 to rotate, and functions to drive the fan head 10 to rotate relative to the support mechanism 20. Among them, in combination with Figure 5 The ion generator 400 includes a high-voltage pack 410 and an excitation brush 420, the high-voltage pack 410 and the excitation brush 420 are electrically connected, and the high-voltage pack 410 and the excitation brush 420 can be one-to-one correspondence, of course, one high-voltage pack 410 can also be connected with multiple excitation brushes 420. From Figure 2As can be seen from the figure, the high-voltage pack 410 is located at the rear side of the rotating motor 500 due to the size of the high-voltage pack 410 being larger than that of the rotating motor 500 along the radial direction of the fan blade 200, so that the ion generator 400 and the fan blade 200 are staggered along the axial direction of the fan blade 200. The excitation brush 420 is located at the front side of the rotating motor 500, and is closer to the air outlet side of the fan blade 200 for the fan blade 200, so as to ensure the airflow speed through the excitation brush 420, ensure the ions to flow out with the airflow, ensure the diffusion effect of the ions in the air, and facilitate the user to observe the ion generator 400 through the front side.

[0047] It is worth mentioning that the excitation brush 420 is located at the front side of the rotating motor 500, and the high-voltage pack 410 is located at the rear side of the rotating motor 500, so as to ensure the purification effect of the ion generator 400, avoid the ion generator from contacting the fan blade 200, the rear mesh cover 120 or the shell 130 and the like too much, and fully utilize the space at the rear inside of the outer cover 100.

[0048] From Figure 6 It can be found from the figure that the excitation brush 420 is fixed to the motor bracket 121 through the screw 600, and of course, the fixing mode and the setting position of the excitation brush 420 are not limited by the example.

[0049] In combination with Figure 1 and Figure 7 , the shell 130 is provided with a protection bin 131, and the ion generator 400 is located in the protection bin 131. The ion generator 400 and the rotating motor 500 can be protected through the protection bin 131. The protection bin 131 adopts a structure conforming to fluid mechanics, and the surface thereof is smooth, so as to avoid the wind resistance from being formed on the outer surface of the protection bin 131. In addition, the protection bin 131 is provided with a relief hole 1311, and the end portion of the excitation brush 420 extends out of the protection bin 131 through the relief hole 1311, so as to ensure the full contact between the airflow and the excitation brush 420.

[0050] According to the embodiment of the application, the front mesh cover 110 is installed on the shell 130 through the screw buckle 111, and the shell 130 and the rear mesh cover 120 are fixed through the threaded connecting piece. Therefore, the front mesh cover 110 is convenient to disassemble and assemble, and the user can disassemble and assemble the front mesh cover 110 at any time. Especially in the case that the front mesh cover 110 is not provided with any electrical component, the front mesh cover 110 can be disassembled and washed frequently. The rear mesh cover 120 and the shell 130 are fixed through the threaded connecting piece, so that the fixing mode of the two is reliable, and the electrical components can be fixed to the rear mesh cover 120 and the shell 130.

[0051] Please refer to Figure 4The window 300 has multiple through holes 310, and the window 300 is detachably mounted to the outer cover 100. The multiple through holes 310 facilitate the diffusion of the ion-carrying gas flow. Furthermore, the window 300 and the outer cover 100 can be detachably mounted; for example, the window 300 can be connected to the outer cover 100 via a snap-fit ​​connection.

[0052] According to embodiments of this application, in conjunction with Figures 1 to 3 The window 300 is positioned corresponding to the pivot 700 of the fan head 10, ensuring its relative position remains constant as the fan head 10 rotates, thus guaranteeing its visibility during operation. Of course, the placement of the window 300 is not limited to this example, as long as airflow passes through the ion generator 400. Furthermore, the number of ion generators 400 is unlimited; multiple generators can be used, distributed circumferentially along the fan blades 200 to ensure sufficient ion carrying capacity in the airflow. The ion generator 400 can generate either positive or negative ions. Taking negative ions as an example, their entry into the air can purify, freshen, and remove smoke and dust, thus eliminating odors and improving air quality. The “window 300 corresponding to the pivot 700 of the fan head 10” includes the following situations: the window 300 is located on the pivot 700; or, the window 300 is located outside the pivot 700, and the distance between the window 300 and the pivot 700 is small, for example, the distance between the window 300 and the pivot 700 is no more than 5cm.

[0053] According to the embodiment of the present application, during operation, when the fan blades 200 rotate, the airflow blows the ions generated by the ion generator 400 into the working space to sterilize and purify the air.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
