[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is 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 invention and are not intended to limit the present invention.

[0023] See also Figure 1-2The present invention provides a front mesh cover 100 and a fan using the same. The front mesh cover 100 includes an outer frame, a disk 20 disposed at the center of the outer frame, and an inner ring mesh branch portion 30, a middle ring mesh branch portion 40, and an outer ring mesh branch portion 50 that diffuse from the disk 20 toward the outer frame. A first wind circle 60 is disposed between the inner ring mesh branch portion 30 and the middle ring mesh branch portion 40, and a second wind circle 70 is disposed between the middle ring mesh branch portion 40 and the outer ring mesh branch portion 50. The inner ring mesh branch portion 30, the middle ring mesh branch portion 40, and the outer ring mesh branch portion 50 diffuse in the same direction toward the outer frame. The front mesh cover 100 provided by the present invention and the fan using the same can effectively change the wind direction, concentrate the wind direction, and increase the wind pressure by using the inner ring mesh branch portion 30, the middle ring mesh branch portion 40, and the outer ring mesh branch portion 50 that diffuse from the disk 20 toward the outer frame, thereby effectively increasing the wind speed and pressure, thereby improving the user experience during use. In addition, since the inner circle mesh branch portion 30, the middle circle mesh branch portion 40 and the outer circle mesh branch portion 50 diffuse in the same direction toward the outer frame, the wind blown out by the fan blades is more concentrated when passing through the front mesh cover 100, thereby further increasing the amount of wind felt by the user and further improving the user's experience during use.

[0024] like Figure 1 In the embodiment provided by the present invention, the inner ring mesh branch portion 30 includes a plurality of inner ring branches 31, the middle ring mesh branch portion 40 includes a plurality of middle ring branches 41, and the outer ring mesh branch portion 50 includes a plurality of outer ring branches 51. The inner ring mesh branch portion 30, the middle ring mesh branch portion 40, and the outer ring mesh branch portion 50 are coaxially arranged. By coaxially arranging the inner ring mesh branch portion 30, the middle ring mesh branch portion 40, and the outer ring mesh branch portion 50, the coaxiality between the inner ring mesh branch portion 30, the middle ring mesh branch portion 40, and the outer ring mesh branch portion 50 can be effectively ensured, thereby effectively concentrating the wind blown by the fan blades through the front mesh cover 100, effectively changing the wind direction of the blown wind, concentrating the wind direction, and increasing the wind pressure, thereby effectively increasing the wind speed and wind pressure, thereby improving the user experience during use. The inner ring branches 31, the middle ring branches 41, and the outer ring branches 51 provided by the present invention all spread out in a spiral shape toward the outer frame. By spreading the inner circle branches 31, the middle circle branches 41 and the outer circle branches 51 in a spiral shape toward the outer frame, the wind blown out by the fan blades can be blown out in a spiral shape along the direction of the inner circle mesh branch part 30, the middle circle mesh branch part 40 and the outer circle mesh branch part 50 and form a spiral columnar wind, thereby increasing the wind pressure, making the wind speed larger and stronger, and thus making the blown wind reach a farther distance, further improving the user experience during use.

[0025] like Figure 1 and Figure 2As shown, the inner ring branches 31, middle ring branches 41, and outer ring branches 51 of the front grille 100 provided by the present invention are all arc-shaped branches. In the embodiment provided by the present invention, the inner ring branches 31 include an inner ring vertical surface 311 and a double arc surface 312 located below the inner ring vertical surface 311 and extending obliquely from the disk 20 toward the first wind circle 60 to form. The inner circle vertical surface 311 of the inner circle branch 31 can effectively increase the wind resistance of the wind generated by the rotation of the fan blade, thereby effectively increasing the wind pressure and improving the wind speed. The double arc surface 312 formed by the disc 20 extending obliquely toward the first wind circle 60 can reduce the wind resistance of the wind generated by the rotation of the fan blade and reduce the wind speed, so that the wind blown out by the fan blade can pass through the double arc surface 312 more smoothly. The combination of the arc-shaped inner circle branch 31 and the inner circle vertical surface 311 and the double arc surface 312 can effectively change the wind direction of the wind blown out by the inner circle branch 31, making the wind direction more concentrated, thereby effectively improving the wind speed while increasing the wind volume, thereby improving the user experience during use.

[0026] like Figure 2 As shown, the middle circle branches 41 provided by the present invention are tilted between the first wind circle 60 and the second wind circle 70 and form a windward inclined vertical surface 411. The tilt angle of the windward inclined vertical surface 411 is smaller than the tilt angle of the double arc surface 312. The middle circle branches 41 provided by the present invention are arc-shaped structures, so they effectively increase the wind resistance of the wind generated by the rotation of the fan blades, thereby effectively increasing the wind pressure and increasing the wind speed. By tilting between the first wind circle 60 and the second wind circle 70 and forming the windward inclined vertical surface 411, it is beneficial to cut the wind, making the wind outlet of the middle circle branches 41 smoother; the combination of the two can effectively increase the wind pressure in the middle circle net branch part 40, thereby effectively increasing the wind speed while increasing the air volume, thereby further improving the user experience during use.

[0027] like Figure 2 As shown, in the embodiment provided by the present invention, the outer ring branches 51 are uprightly arranged between the second wind circle 70 and the outer frame and form an outer ring upright surface 511. The outer ring branches 51 provided by the present invention are of an arc-shaped structure, thereby effectively increasing the wind resistance of the wind generated by the rotation of the fan blades, thereby effectively increasing the wind pressure and speed. On this basis, by being uprightly arranged between the second wind circle 70 and the outer frame and forming the outer ring upright surface 511, the wind resistance can be further increased, thereby further increasing the wind pressure within the outer ring network branch portion 50, thereby effectively increasing the wind speed while increasing the air volume, thereby further improving the user experience during use.

[0028] like Figure 2As shown, the utility model also provides a fan, including the above-mentioned front mesh cover 100, wherein a plurality of buckles 11 are provided on the outer wall of the outer frame of the front mesh cover 100, thereby effectively improving the convenience of installation between the front mesh cover 100 and the casing or rear mesh of the fan, simplifying the installation steps, and improving the installation efficiency.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
