[0026] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0027] See Figures 1-7, is a mesh cover structure 100 of an electric fan provided by the utility model, the mesh cover structure 100 of the electric fan comprises a shell, a front mesh 10 arranged at the front end of the shell, and an inner ring 20 rotatably connected to the front mesh 10, the front mesh 10 and the inner ring 20 are provided with a rotating structure for toggling the inner mesh relative to the front mesh 10 and a limiting structure for limiting the rotation angle of the inner mesh relative to the front mesh 10, a plurality of first ventilation holes 11 are provided on the outer edge surface of the front mesh 10, a plurality of second ventilation holes 21 are provided on the inner ring 20, and the rotating structure is toggled to make the first ventilation holes 11 communicate with or not communicate with the second ventilation holes 21. The mesh cover structure 100 of the electric fan provided by the utility model is in a closed state, by using a rotating component to rotate the inner ring 20 counterclockwise relative to the front mesh 10, so that the first ventilation hole 11 and the second ventilation hole 21 are not connected. At this time, the inner ring 20 can effectively block the side wind inlet area of the front mesh 10, so that the side of the front mesh 10 forms a duct structure, thereby effectively increasing the air volume blown out by the electric fan and meeting the user's demand for large air volume; in an open state, by using a rotating component to rotate the inner ring 20 clockwise relative to the front mesh 10, so that the first ventilation hole 11 and the second ventilation hole 21 are connected. At this time, the inner ring 20 can effectively increase the air inlet area of the front mesh 10, thereby effectively increasing the wind speed blown out by the electric fan and meeting the user's demand for high wind speed, thereby realizing the operation of separately adjusting the air volume or wind speed, meeting the different usage requirements of users, and improving the user's experience during use. In addition, the limiting structure can effectively limit the rotation angle of the inner ring 20 relative to the front net 10, thereby ensuring the accuracy of whether the first ventilation hole 11 and the second ventilation hole 21 are connected or not, thereby ensuring that the user's needs for increasing the air volume or wind speed are met, thereby improving the user's experience during use.
[0028] like Figures 1-4As shown, in the embodiment provided by the utility model, the shapes of the first ventilation hole 11 and the second ventilation hole 21 are matched, and the area of the first ventilation hole 11 is smaller than the area of the second ventilation hole 21. By matching the shapes of the first ventilation hole 11 and the second ventilation hole 21, the air intake volume of the side of the front net 10 can be effectively guaranteed when the first ventilation hole 11 and the second ventilation hole 21 are connected, thereby effectively ensuring the effect of increasing the wind speed. In addition, since the area of the first ventilation hole 11 is smaller than the area of the second ventilation hole 21, the speed of the ambient wind entering the inner ring 20 through the first ventilation hole 11 can be effectively increased, thereby further improving the effect of increasing the wind speed. In the embodiment provided by the present invention, the first ventilation holes 11 and the second ventilation holes 21 are both strip holes and are radially arranged on the front net 10 and the inner ring 20, thereby further improving the speed of the ambient wind entering the inner ring 20 through the first ventilation holes 11, and by arranging a plurality of third ventilation holes 12 at the front end of the front net 10, the plurality of third ventilation holes 12 are spirally shaped at the front end of the front net 10, which can effectively ensure the air outlet at the front end of the front net 10, thereby increasing the air volume blown out through the third ventilation holes 12 through the air duct structure formed on the side of the front net 10 when the first ventilation holes 11 and the second ventilation holes 21 are not connected, thereby better meeting the user's demand for large air volume.
[0029] like Figure 1 , Figure 4 and Figure 7 As shown, in the embodiment provided by the utility model, the rotating structure includes a paddle 22 arranged on the inner net and a rotating groove 13 arranged on the front net 10, and the top of the paddle 22 passes through the rotating groove 13. By manually toggling the paddle 22 by the user to make the inner ring 20 rotate counterclockwise or clockwise relative to the front net 10, the air inlet area can be adjusted, thereby achieving the effect of adjusting the fan wind speed and air volume, satisfying the user's need to increase the air volume or increase the wind speed, effectively improving the convenience of user operation, and reducing production costs. The paddle 22 provided by the utility model is a rectangular paddle 22, and the rotating groove 13 is a strip groove adapted to the shape of the paddle 22. The rotating groove 13 of the strip groove can effectively limit the displacement of the user toggling the paddle 22, thereby further limiting the angle of rotation of the inner ring 20 relative to the front net 10 driven by the user toggling the paddle 22, and further improving the accuracy of adjusting the air inlet area.
[0030] like Figure 1 , Figure 3 and Figure 6As shown, the limiting structure includes a plurality of groups of limiting grooves 14 provided on the inner wall of the inner ring 20 and a limiting boss 23 provided on the inner wall of the front net 10 and embedded in the limiting grooves 14, and the number of the limiting grooves 14 in each group of limiting grooves 14 is the same. The number of the plurality of limiting bosses 23 is the same as the number of the plurality of groups of limiting grooves 14, and the limiting bosses 23 are embedded in the limiting grooves 14, so that the inner ring 20 and the front net 10 are fixed by being locked. In the embodiment provided by the utility model, four groups of limiting grooves 14 are arranged on the inner wall of the inner ring 20, each group of limiting grooves 14 includes two limiting grooves 14, and the spacing between the two limiting grooves 14 in each group is the same, and four limiting bosses 23 are correspondingly arranged on the inner wall of the front net 10. When the user turns the paddle 22 to drive the inner ring 20 to rotate relative to the front net 10 until the four limiting bosses 23 on the front net 10 are respectively embedded in one of the limiting grooves 14 in the four groups of limiting grooves 14, the inner ring 20 is embedded and fixed with the front net 10, thereby further limiting the angle of rotation of the inner ring 20 relative to the front net 10 driven by the user to turn the paddle 22, and further improving the accuracy of adjusting the air inlet area.
[0031] like Figure 1 , Figure 3 and Figure 6 As shown, in the embodiment provided by the utility model, the limiting boss 23 is a hemispherical boss, and the limiting groove 14 is a hemispherical groove that matches the shape of the hemispherical boss. By setting the limiting boss 23 as a hemispherical boss, and setting the limiting groove 14 as a hemispherical groove that matches the shape of the hemispherical boss, the smoothness of the limiting boss 23 being inserted into the limiting groove 14 and being removed from the limiting groove 14 can be effectively improved, the convenience of user operation is improved, and the user experience during use is further improved.
[0032] like Figure 1 , Figure 2 and Figure 5As shown in the figure, there is also a schematic convex part 15 provided on the front net 10. The paddle 22 is aligned with the schematic convex part 15, and the first ventilation hole 11 is not connected to the second ventilation hole 21. When the paddle 22 is not aligned with the schematic convex part 15, the first ventilation hole 11 is connected to the second ventilation hole 21. The schematic convex part 15 can effectively prompt the user whether the front net 10 and the inner ring 20 are in an open state or a closed state. When the paddle 22 is aligned with the schematic convex part 15, the inner ring 20 and the front net 10 are in a closed state. At this time, the first ventilation hole 11 is not connected to the second ventilation hole 21, and the inner ring 20 can effectively block the side air intake area of the front net 10, forming a duct structure on the side of the front net 10, thereby effectively increasing the air volume blown by the electric fan and meeting the user's demand for a large air volume. When the paddle 22 is not aligned with the schematic convex part 15, the inner ring 20 and the front net 10 are in an open state. At this time, the first ventilation hole 11 is connected to the second ventilation hole 21. At this time, the inner ring 20 can effectively increase the air intake area of the front net 10, thereby effectively increasing the wind speed blown by the electric fan and meeting the user's demand for a high wind speed, thus realizing the operation of separately adjusting the air volume or the wind speed, meeting the different usage requirements of the user, and improving the user experience during use.
[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
