In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] like Figure 1 As shown, the present invention proposes an anti-shake mesh cover, including a mesh cover body 1, and a support member 4 fixedly connected to the mesh cover body 1. The support member 4 is fixed to the mesh cover body 1, thereby improving the fixing stiffness of the mesh cover body 1, increasing the natural frequency, and reducing the shake of the mesh cover body 1.

[0033] like Figure 2 As shown, a shock absorbing structure is provided between the support member 4 and the mesh cover body 1, thereby reducing the vibration of the anti-shake mesh cover. Alternatively, the shock absorbing structure may not be provided, and the vibration of the anti-shake mesh cover may be reduced by fixing the support member 4 and the mesh cover body 1. The specific structure of the anti-shake mesh cover is described below through two embodiments. Of course, the structure of the anti-shake mesh cover provided by the present invention is not limited to these several combinations, but may also be other combinations, which are not specifically limited here, and are only described in detail with these two embodiments. Example

[0034] like Figure 4 As shown, the anti-shake mesh provided by the embodiment of the present invention comprises a mesh body 1, and an assembly hole 12 is provided on the mesh body 1. The assembly hole 12 is generally mounted on the head of the fan, and a matching portion is provided on the mesh body 1. The matching portion is arranged on the outer surface of the mesh body 1, so that the support member 4 is fixedly arranged on the outer surface of the mesh body 1. The outer surface mentioned here refers to the surface of the mesh body 1 away from the fan blades when the fan blades are installed. The mesh body 1 is generally a rear mesh, and the rear mesh and the support frame are fixed before being installed on the head. The anti-shake mesh provided by the embodiment of the present invention adopts a method of moving the fixation outward to the mesh, and changing the single-point fixation to a multi-point fixation method, so as to improve the fixing stiffness of the mesh, increase the fixing frequency, avoid the resonance range with the fan blades, reduce the mutual vibration between the head vibration and the fan blade excitation, and reduce the shaking.

[0035] like Figure 5As shown, the support member 4 includes a first body, and the first body is fixedly connected to the second body. The first body and the second body can be integrally formed or welded and fixed separately. Preferably, the first body and the second body are integrally formed. The first body is an annular shell. Of course, the shape and structure of the first body are the same as the shell structure set on the rear net and fixed to the head in the existing fan. The first body has a through hole, and the through hole is mainly installed with the head. The second body is an arc bracket. The arc bracket here can be a semicircular bracket or a circular bracket, or a bracket of other shapes. No specific limitation is made here. The circular or semicircular bracket is set to increase the fixed position of the mesh cover body 1 and the support member 4, so that the single-point fixation is converted into a multi-point fixation method, the fixing stiffness of the mesh cover is improved, the fixing frequency is increased, and the resonance interval with the fan blade is avoided. The vibration of the fan head and the vibration of the fan blade can be reduced, and the vibration can be reduced.

[0036] Furthermore, a snap-fitting part and a fixing part are provided on the second body. The fixing part is provided at the top corner of the bracket. The fixing part includes multiple parts. The fixing part can be specifically provided as an installation groove 41. A through hole is provided in the groove body of the installation groove 41 so that the fixing part and the mesh cover body 1 are connected by screws 5.

[0037] Specifically, the snap-fitting part is a snap 42, which is fixed on the bracket. The snap 42 is arranged on the bracket on the side installed with the mesh cover body 1, and the snap 42 is provided with an elastic arm, which is snap-fitted with the mesh cover body 1 so that the mesh cover body 1 and the first body are snap-fitted and fixed.

[0038] Preferably, a matching portion is provided on the mesh cover body 1, and the matching portion is provided on the assembly hole 12 of the mesh cover body 1. A block 13 is provided on the inner wall of the assembly hole 12, and the specific number of the blocks 13 is four. Of course, the number of blocks 13 is not limited to four, and can also be set to multiple, which is not specifically limited here. Multiple blocks 13 are evenly distributed along the circumference of the inner wall of the assembly hole 12. Similarly, the buckles 42 are evenly provided on the two side walls of the first body with the center of the first body as the symmetry axis. The number of buckles 42 is also set to multiple, which can be specifically limited according to the shape of the bracket.

[0039] Of course, the number of the buckles 42 matches the number of the clamping blocks 13 so that the buckles 42 and the clamping blocks 13 are clamped and fixed.

[0040] Preferably, the mesh body 1 can be made of a variety of materials, such as a plastic mesh or a metal mesh, which is not specifically limited here. The assembly hole 12 provided on the mesh body 1 can also be square, circular or other shapes.

[0041] In the specific installation process of the anti-shake net cover provided by the present invention, the fixing part on the support member 4 and the installation hole 11 are first fixed, and then the buckle 42 provided on the support member 4 and the clamping block 13 are clamped together to realize the fixed installation of the support member 4 and the net cover body 1. By arranging the support member 4 between the machine head and the net cover body 1, the mutual vibration between the machine head vibration and the fan blade excitation vibration can be reduced, thereby reducing the shaking.

[0042] The electric fan does not vibrate or vibrates inconspicuously in all speeds of the fan in normal use, thus solving the vibrating problem and improving the user experience; the vibration frequency is positively correlated with the stiffness of the vibrating object, the stronger the stiffness, the greater the vibration frequency, and the speed of the fan changes evenly between various speeds, for example: 500 rpm in the first gear, 700 rpm in the second gear, and 900 rpm in the third gear. The inherent vibration frequency of the mesh cover body 1 is 700 rpm, and at this time, the strength of the mesh cover body 1 can be increased to adjust the vibration frequency of the mesh cover body 1 to 800 rpm, so that the two frequencies are different and the mesh cover body 1 does not follow the resonance. Example

[0043] like Figure 6 and Figure 7 As shown, the anti-shake mesh cover provided by the embodiment of the present invention comprises a mesh cover body 1, a mounting hole 12 is provided on the mesh cover body 1, the mounting hole 12 is generally mounted with the head of the fan, and a matching part is provided on the mesh cover body 1, and the matching part is provided on the outer surface of the mesh cover body 1, so that the support member 4 is fixedly provided on the outer surface of the mesh cover body 1. A shock absorbing structure is provided between the support member 4 and the mesh cover body 1, and the addition of the shock absorbing structure can further reduce the shaking of the mesh cover body 1 and improve the user experience.

[0044] Furthermore, the shock absorbing structure includes a first shock absorbing pad 2 and a second shock absorbing pad 3. The first shock absorbing pad 2 and the second shock absorbing pad 3 can be provided simultaneously or separately. The specific provision form is not specifically limited as long as the support member 4 and the mesh cover body 1 can be isolated.

[0045] like Figure 6 As shown, the first shock-absorbing pad 2 is a rubber ring, and of course it can also be set as a silicone ring. The specific structure of the first shock-absorbing pad 2 is not specifically limited here, and it can also be set to be made of other materials.

[0046] Further, a card slot 22 is provided on the outer wall of the first shock-absorbing pad 2, and the card slot 22 cooperates with the assembly hole 12 so that the card slot 22 and the hole wall of the assembly hole 12 cooperate. A plurality of card holes 21 are provided on the inner wall of the card slot 22, and the number of the card holes 21 and the card blocks 13 match so that the card holes 21 and the card blocks 13 cooperate, thereby interference fitting the first shock-absorbing pad 2 on the mesh cover body 1, so that the first shock-absorbing pad 2 isolates the mesh cover body 1 from direct contact with the support member 4.

[0047] like Figure 7As shown, the second shock absorbing pad 3 is arranged in the installation groove 41, and a fixing hole 31 is arranged on the second shock absorbing pad 3. The fixing hole 31 and the installation hole 11 are fixedly connected by screws 5 to fix the mesh cover body 1, the second shock absorbing pad 3 and the support member 4.

[0048] Preferably, the number of the second shock-absorbing pads 3 is the same as the number of the mounting slots 41 , and a second shock-absorbing pad 3 is disposed in each mounting slot 41 , so that the second shock-absorbing pad 3 isolates the direct contact between the mesh cover body 1 and the support member 4 .

[0049] Of course, the second shock-absorbing pad 3 is a rubber ring or a silicone ring, and can also be made of other materials, which is not specifically limited here.

[0050] The anti-shake mesh cover provided in the above embodiment first fixes the first shock-absorbing pad 2 and the assembly hole 12, and then places the second shock-absorbing pad 3 in the installation groove 41, so that the fixing part of the support member 4 and the installation hole 11 of the mesh cover body 1 are fixedly connected, and then the buckle 42 and the block 13 are snapped together to fix the support member 4 on the mesh cover body 1.

[0051] The above embodiment improves the fixing stiffness of the mesh cover by changing the single-point fixing to a multi-point fixing method, increases the fixing frequency, avoids the resonance range with the fan blades, reduces the vibration of the head and the vibration of the fan blades, and reduces the vibration. In normal use of the electric fan, there is no vibration or the vibration is not obvious, etc., which solves the vibration problem and improves the user experience.

[0052] The present invention also provides a fan, including a head, which is connected to the anti-shake mesh cover mentioned above. The fixing stiffness of the mesh cover is improved and the shaking is reduced by fixed outward movement. The fixed outward movement refers to radial outward movement, that is, the position of the fixed mesh cover with a larger diameter is increased to increase the strength of the mesh cover. The isolated installation can reduce the mutual vibration of the head vibration and the fan blade excitation, thereby reducing the shaking. The fixed outward movement can increase the fixed frequency to avoid the resonance range with the fan blade and reduce the shaking.

[0053] Specifically, a plug hole 43 is provided on the first body, and an elastic arm 44 is provided on one side of the plug hole 43. During the installation process, the machine head and the clamping part are matched to fix the machine head and the first body.

[0054] The fan provided in the embodiment of the present invention is different from the traditional fixing method. It adopts a method of fixing the fan outside the mesh cover body 1, changing from a single-point fixing to a multi-point fixing method, thereby improving the fixing stiffness of the mesh cover body 1, increasing the fixing frequency, avoiding the resonance range with the fan blades, and reducing the vibration of the head and the vibration of the fan blades, thereby reducing the vibration. In the normal use of the electric fan, there is no vibration or the vibration is not obvious, etc., which solves the vibration problem and improves the user experience.

[0055] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
