Description

Technical Field

[0001] The present invention relates to the field of air conditioners, and more particularly, to a grille structure and an air conditioner. Background Art

[0002] At present, the grille of the top-outlet air conditioner outdoor unit commonly uses a wire mesh to protect the fan blades. The overall grille is planar, and such a grille has relatively weak self-structural strength and is prone to deformation. For example, in the working condition of ice and snow accumulation, the grille will collapse downward, and in severe cases, it may interfere with and damage the blades.

[0003] In view of this, the present invention is specifically proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a grille structure and an air conditioner to solve the problems in the prior art that the overall grille is planar, the self-structural strength of the grille is relatively weak and prone to deformation, and in severe cases of ice and snow accumulation, it may interfere with and damage the blades, resulting in relatively low safety.

[0005] To achieve the above object, the technical solution of the present invention is implemented as follows:

[0006] A grille structure, the grille structure includes a grille body, a central plate, main ribs and cover body rib strips are arranged on the grille body, the cover body rib strips are arranged on the periphery of the central plate, the main ribs are arranged on the cover body rib strips, one end of the main rib is connected to the central plate, and the other end of the main rib extends along the radial direction of the grille body and towards the outside of the grille body. The overall grille body is conical. The intersection point of the main rib and the outermost cover body rib strip is point A, and the intersection point of the main rib and the central plate is point B. The included angle β between the connection line between point A and point B and the cover body rib strip satisfies: 3° ≤ β ≤ 5°;

[0007] A strengthening device is arranged on the grille body. The strengthening device at least includes a first strengthening structure, and the first strengthening structure is arranged between two adjacent main ribs;

[0008] An extension part is arranged on the grille body, and an extension fitting part is arranged on the top cover plate. The extension part is arranged above the extension fitting part. The extension part can displace relative to the extension fitting part, and the extension part is used to be attached to or separated from the extension fitting part;

[0009] The extension fitting part is arranged as a groove;

[0010] The extension part includes an extension body section and an inclined connection section. One end of the inclined connection section is connected to the extension body section, and the other end of the inclined connection section is connected to the grille body.

[0011] A kind of mesh cover structure described in this embodiment has the following advantages: First, it has a good effect on improving the strength of the mesh cover. Under the condition of ice and snow accumulation, it is not easy to deform and has high safety. Second, the height of the mesh cover is not very high, thus avoiding the increase of consumables and further avoiding the increase of the overall height and packaging cost of the whole machine. Third, it improves the overall aesthetics of the mesh cover.

[0012] Furthermore, the main ribs are set to be straight or arc-shaped.

[0013] This setting can, on the one hand, ensure the structural strength of the mesh cover; on the other hand, it is beneficial to air outlet.

[0014] Furthermore, the cover ribs are set to be annular, and the cover ribs are concentric with the central plate.

[0015] This setting can, first, ensure the structural strength and balance of the mesh cover; second, be beneficial to air outlet; third, improve the overall aesthetics of the mesh cover.

[0016] Furthermore, the cover ribs are arranged in a spiral shape on the mesh cover body.

[0017] This setting can both ensure the structural strength of the mesh cover and be beneficial to air outlet.

[0018] Furthermore, the distance c between two adjacent cover ribs satisfies: c ≤ 7.6 mm.

[0019] This setting can, first, ensure that it is difficult for children's fingers to enter, meet the requirements of children's test fingers, and have high safety; second, ensure the structural strength of the mesh cover; third, be beneficial to air outlet.

[0020] Furthermore, the distance between two adjacent cover ribs is set to be equal or set to decrease proportionally from the inside to the outside along the radial direction of the mesh cover body.

[0021] This setting can both ensure the structural strength of the mesh cover and be beneficial to air outlet.

[0022] Furthermore, the first strengthening structure and the main ribs are arranged on the same side or opposite sides of the cover ribs.

[0023] This setting can, on the one hand, strengthen the structural strength of the mesh cover; on the other hand, be beneficial to air outlet. The same-side setting has a better effect on wind guidance, improves the wind speed and pressure at the air outlet, and the wind beam is more concentrated, which has an obvious improvement in the case of poor air inlet and outlet of the unit; the opposite-side setting is beneficial to the air volume.

[0024] Furthermore, the main ribs are evenly distributed in a circle on the mesh cover body, and the first strengthening structure is arranged on the angular bisector between two adjacent main ribs.

[0025] This setting improves the structural strength and support balance of the mesh cover.

[0026] Furthermore, the number of the main ribs is set to be positively correlated with the diameter of the mesh cover body.

[0027] This setting can, on the one hand, strengthen the structural strength of the mesh cover; on the other hand, it is beneficial to air outlet.

[0028] In the second aspect of the present invention, an air conditioner is proposed. The air conditioner uses any one of the described mesh cover structures. The air conditioner further includes a top cover plate, and air outlet holes are provided on the top cover plate. The mesh cover structure is matched with the air outlet holes; first mounting holes are provided on the mesh cover body of the mesh cover structure, and second mounting holes are provided on the top cover plate. The first mounting holes are matched with the second mounting holes.

[0029] Compared with the prior art, for the mesh cover structure and the air conditioner of the present invention, first, the strength improvement effect of the mesh cover is good, and it is not easy to deform under the working condition of ice and snow accumulation, with relatively high safety; second, the height of the mesh cover will not be very high, thus avoiding the increase of consumables and further avoiding the increase of the overall height and packaging cost of the whole machine; third, the overall aesthetics of the mesh cover is improved.

The descriptions such as "first" and "second" mentioned in the embodiments of the present invention are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement them. When the combination of technical solutions appears to be contradictory or unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0045] The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments. Embodiment 1

[0046] This embodiment provides a kind of mesh cover structure, as Figures 1 - 3 shown, the mesh cover structure includes a mesh cover body 1, a central plate 13, main ribs 14 and cover body ribs 16 are arranged on the mesh cover body 1, the cover body ribs 16 are arranged on the periphery of the central plate 13, the main ribs 14 are arranged on the cover body ribs 16, one end of the main rib 14 is connected to the central plate 13, and the other end of the main rib 14 extends along the radial direction of the mesh cover body 1 and towards the outside of the mesh cover body 1, as Figure 3As shown, the entire mesh cover body 1 is in a conical shape.

[0047] In a mesh cover structure described in this embodiment, the entire mesh cover body 1 is in a conical shape, effectively increasing the strength of the mesh cover. Under the condition of ice and snow accumulation, it is not easy to deform, thus improving safety.

[0048] Specifically, the intersection point of the main rib 14 and the outermost cover body rib 16 is point A, and the intersection point of the main rib 14 and the central plate 13 is point B. If the included angle between the connection line between point A and point B and the cover body rib 16 is too small, the improvement of the mesh cover strength is small; if the included angle between the connection line between point A and point B and the cover body rib 16 is too large, the greater the height of the mesh cover, the more materials are consumed, which will cause an increase in the overall height of the machine and the packaging cost, and affect the aesthetics.

[0049] Specifically, the included angle β between the connection line between point A and point B and the cover body rib 16 satisfies: 3° ≤ β ≤ 5°.

[0050] This setting, first, has a good effect on improving the strength of the mesh cover. Under the condition of ice and snow accumulation, it is not easy to deform and has high safety; second, the height of the mesh cover will not be very high, thus avoiding the increase of materials consumed, and further avoiding the increase of the overall height of the machine and the packaging cost; third, it improves the overall aesthetics of the mesh cover.

[0051] Preferably, in this embodiment, as Figure 3 shown, the included angle β between the connection line between point A and point B and the cover body rib 16 = 5°.

[0052] This setting, first, has the best effect on improving the strength of the mesh cover; second, the height of the mesh cover will not be very high, thus avoiding the increase of materials consumed, and further avoiding the increase of the overall height of the machine and the packaging cost; third, it improves the overall aesthetics of the mesh cover.

[0053] Specifically, the central plate 13 is installed at the center of the mesh cover body 1, and the central plate 13 is used to install the motor of the fan.

[0054] Specifically, the shape of the central plate 13 is not specifically limited. The shape of the central plate 13 can be circular, the shape of the central plate 13 can also be square, and the shape of the central plate 13 can also be rectangular.

[0055] More specifically, in this embodiment, preferably, as Figure 1 and Figure 2 shown, the shape of the central plate 13 is circular. This setting is convenient for matching with the motor installed below the mesh cover body 1 and can ensure the installation strength of the mesh cover.

[0056] Specifically, the shape of the mesh cover body 1 is not specifically limited. The shape of the mesh cover body 1 can be circular, the shape of the mesh cover body 1 can also be square, and the shape of the mesh cover body 1 can also be rectangular.

[0057] More specifically, in this embodiment, preferably, as Figure 1 and Figure 2 shown, the shape of the mesh cover body 1 is circular. This setting facilitates the cooperation with the fan installed below the mesh cover body 1, which can not only ensure the air outlet effect but also ensure the installation strength of the mesh cover.

[0058] Specifically, the main ribs 14 are set to be straight or arc-shaped.

[0059] This setting can, on the one hand, ensure the structural strength of the mesh cover; on the other hand, it is beneficial to air outlet.

[0060] Preferably, in this embodiment, as Figure 1 and Figure 2 shown, the main ribs 14 are set to be straight.

[0061] This setting greatly improves the structural strength of the mesh cover while ensuring the air outlet effect.

[0062] Specifically, the cover ribs 16 are set to be annular, and the cover ribs 16 are concentric with the central plate 13.

[0063] This setting can, firstly, ensure the structural strength and balance of the mesh cover; secondly, it is beneficial to air outlet; thirdly, it can improve the overall aesthetics of the mesh cover.

[0064] Specifically, the setting that the cover ribs 16 are annular is not specifically limited. The cover ribs 16 can be set as circular annular, and the cover ribs 16 can also be set as square annular.

[0065] Preferably, in this embodiment, as Figure 1 and Figure 2 shown, the cover ribs 16 are set as circular annular.

[0066] Specifically, the spacing distance c between two adjacent cover ribs 16 satisfies: c ≤ 7.6 mm.

[0067] This setting can, firstly, ensure that it is difficult for children's fingers to enter, meet the requirements of children's test fingers, and has high safety; secondly, it can ensure the structural strength of the mesh cover; thirdly, it is beneficial to air outlet.

[0068] Preferably, in this embodiment, as Figure 2 shown, the spacing distance c between two adjacent cover ribs 16 satisfies: c = 7.6 mm.

[0069] This setting, firstly, can ensure that it is difficult for children's fingers to enter, meet the requirements of the children's test finger, and has high safety; secondly, it can ensure the structural strength of the mesh cover; thirdly, it is conducive to air outlet.

[0070] Specifically, the interval distance between two adjacent cover body rib strips 16 is set to be equal or set to decrease in equal proportion from the inside to the outside along the radial direction of the mesh cover body 1.

[0071] This setting can not only ensure the structural strength of the mesh cover but also be conducive to air outlet.

[0072] Preferably, in this embodiment, as Figure 1 and Figure 2 shown, the interval distance between two adjacent cover body rib strips 16 is set to be equal.

[0073] This setting can not only ensure the structural strength and support balance of the mesh cover but also be conducive to air outlet.

[0074] Specifically, a strengthening device 15 is provided on the mesh cover body 1. The strengthening device 15 at least includes a first strengthening structure 151, and the first strengthening structure 151 is arranged between two adjacent main ribs 14.

[0075] This setting further strengthens the structural strength of the mesh cover.

[0076] Specifically, the first strengthening structure 151 and the main rib 14 are arranged on the same side or opposite sides of the cover body rib strip 16.

[0077] This setting, on the one hand, can strengthen the structural strength of the mesh cover; on the other hand, it is conducive to air outlet. When the first strengthening structure 151 and the main rib 14 are arranged on the same side of the cover body rib strip 16, the air guiding effect on the wind is better, the wind speed and pressure at the air outlet are increased, and the wind beam is more concentrated, which has a more obvious improvement in the case of poor air inlet and outlet of the unit; arranging them on the opposite sides is beneficial to the air volume.

[0078] Specifically, the first strengthening structure 151 and the main rib 14 are arranged on the same side of the cover body rib strip 16.

[0079] The radial direction of the mesh cover body 1 is divided into an inner interval, a middle interval, and an outer interval from the inside to the outside.

[0080] Preferably, in this embodiment, as Figure 1 and Figure 2 shown, in the middle interval and the outer interval, the first strengthening structure 151 and the main rib 14 are arranged on the same side of the cover body rib strip 16, the air guiding effect on the wind is better, the wind speed and pressure at the air outlet are increased, and the wind beam is more concentrated, which has a more obvious improvement in the case of poor air inlet and outlet of the unit.

[0081] As Figure 1 and Figure 2 shown, the main reinforcement bars 14 are arranged above the cover reinforcement bars 16 in the inner interval, middle interval, and outer interval, and the first strengthening structure 151 is arranged above the cover reinforcement bars 16 in the middle interval and outer interval.

[0082] This arrangement can strengthen the structural strength of the wire mesh cover on the one hand; on the other hand, it is beneficial to air outlet.

[0083] Specifically, the first strengthening structure 151 is not specifically limited. The first strengthening structure 151 can be arranged as a continuous reinforcing rib or multiple spaced reinforcing ribs.

[0084] Preferably, in this embodiment, as Figure 1 and Figure 2 shown, the first strengthening structure 151 is arranged as a continuous reinforcing rib. This arrangement greatly improves the structural strength of the wire mesh cover.

[0085] Specifically, the main reinforcement bars 14 are evenly distributed in a circular pattern on the wire mesh cover body 1, and the first strengthening structure 151 is arranged on the angular bisector between two adjacent main reinforcement bars 14.

[0086] This arrangement improves the structural strength and support balance of the wire mesh cover.

[0087] Specifically, the number of the main reinforcement bars 14 is not limited.

[0088] If the number of the main reinforcement bars 14 is small, the strength of the wire mesh cover is insufficient; if the number of the main reinforcement bars 14 is large, the bars of the main reinforcement bars 14 are too dense, which affects the air volume.

[0089] Specifically, the number of the main reinforcement bars 14 and the diameter of the wire mesh cover body 1 are set to be positively correlated. The larger the diameter of the wire mesh cover body 1, the more the number of the main reinforcement bars 14 should be. The number of the main reinforcement bars 14 increases as the diameter of the wire mesh cover body 1 increases.

[0090] This arrangement can strengthen the structural strength of the wire mesh cover on the one hand; on the other hand, it is beneficial to air outlet.

[0091] More specifically, the diameter d of the wire mesh cover body 1 is 767 mm, and the number b of the main reinforcement bars 14 satisfies: 3 ≤ b ≤ 6.

[0092] This arrangement can strengthen the structural strength of the wire mesh cover on the one hand; on the other hand, it is beneficial to air outlet.

[0093] Preferably, in this embodiment, as Figure 1 and Figure 2 shown, the diameter d of the wire mesh cover body 1 is 767 mm, and the number b of the main reinforcement bars 14 is 6.

[0094] This setting makes the structural strength and air outlet effect of the mesh cover the best.

[0095] Specifically, the material of the mesh cover structure is not limited. The material of the mesh cover structure is plastic, steel wire, etc. Preferably, in this embodiment, the material of the mesh cover structure is steel wire. For this mesh cover structure, in addition to including the central plate 13, main ribs 14 and cover body rib strips 16, it also includes other related components. Since the specific structures and specific assembly relationships of its related components are all prior arts, they will not be elaborated here.

[0096] Specifically, the mesh cover is installed on the top cover plate 2 through the connecting piece 3. A second installation hole 21 is provided on the top cover plate 2. One end of the main rib 14 is connected to the central plate 13, and a first installation hole 11 is provided at the other end of the main rib 14. The first installation hole 11, the second installation hole 21 and the connecting piece 3 cooperate with each other.

[0097] This setting facilitates the connecting piece 3 to sequentially pass through the first installation hole 11 and the second installation hole 21 to connect the mesh cover body 1 to the top cover plate 2, improving the installation efficiency; on the other hand, it can improve the installation strength and installation structure balance between the mesh cover body 1 and the top cover plate 2.

[0098] For the mesh cover structure described in this embodiment, firstly, it has a good effect on improving the strength of the mesh cover. Under the working condition of ice and snow accumulation, it is not easy to deform and has high safety; secondly, the height of the mesh cover will not be very high, thus avoiding the increase of consumables and further avoiding the increase of the overall height and packaging cost of the machine; thirdly, it improves the overall aesthetics of the mesh cover. Embodiment 2

[0099] Different from Embodiment 1, preferably, in this embodiment, as Figure 4 shown, the main rib 14 is set to be arc-shaped.

[0100] This setting ensures the structural strength and is beneficial to air outlet, can reduce wind resistance, improve the air circulation performance, accelerate the wind speed, and increase the air volume. Embodiment 3

[0101] When the diameter d of the mesh cover is relatively large (mesh cover diameter ≥ 780 mm), the stiffness of the mesh cover is low and the mesh cover is easy to deform.

[0102] Different from Embodiment 1, specifically, as Figure 5 shown, the strengthening device 15 further includes a second strengthening structure 152. The second strengthening structure 152 is arranged on the outer side of the mesh cover body 1, and the distance between the second strengthening structure 152 and the outermost cover body rib strip 16 is set to 5 mm.

[0103] This setting further increases the stiffness of the mesh cover, making it not easily deformed.

[0104] Specifically, the second strengthening structure 152 is not specifically limited. The second strengthening structure 152 can be set as a continuous reinforcing rib or multiple spaced reinforcing ribs.

[0105] Preferably, in this embodiment, as Figure 5 shown, the second strengthening structure 152 is set as a continuous reinforcing rib. This setting greatly improves the structural strength and stiffness of the mesh cover.

[0106] Preferably, in this embodiment, as Figure 5 shown, the cover ribs 16 are arranged in a spiral shape on the mesh cover body 1.

[0107] This setting increases the elasticity of the mesh cover, which is beneficial for the central plate 13 to carry the motor; it is also beneficial for air outlet. Embodiment 4

[0108] At present, although the relatively many connecting pieces 3 used for installing the external machine mesh cover can ensure strength, the assembly efficiency is low, and the contact noise between the mesh cover and the top cover plate 2 is relatively large; although using fewer connecting pieces 3 for installing the mesh cover improves the assembly efficiency and reduces the contact noise between the mesh cover and the top cover plate 2, the strength of the mesh cover is relatively poor, and the mesh cover is easily deformed under force.

[0109] Different from Embodiment 1, as Figures 6 - 12 shown, an extension part 12 is provided on the mesh cover body 1, and an extension mating part 22 is provided on the top cover plate 2. The extension part 12 is arranged above the extension mating part 22. The extension part 12 can displace relative to the extension mating part 22, and the extension part 12 is used to be attached to or separated from the extension mating part 22.

[0110] This setting: First, when no external force is applied, the extension part 12 and the extension mating part 22 are separated, reducing the contact noise between the mesh cover and the top cover plate 2 and preventing wear; Second, when an external force is applied, the extension part 12 and the extension mating part 22 are attached, and the extension mating part 22 generates an upward bearing force on the extension part 12, increasing the strength of the mesh cover body 1, preventing the mesh cover from deforming excessively and rubbing against the fan blade, damaging the fan blade, and improving the installability; Third, the settings of the extension part 12 and the extension mating part 22 reduce the use of the connecting piece 3 and improve the installation efficiency.

[0111] Specifically, the extension part 12 and the extension mating part 22 are separated, and the separation distance D between the extension part 12 and the extension mating part 22 is not limited.

[0112] More specifically, the separation distance D between the extension part 12 and the extension mating part 22 satisfies: D≥3mm.

[0113] This setting can ensure that when no external force is applied, the contact noise between the wire mesh cover and the top cover plate 2 is reduced, preventing wear.

[0114] Preferably, in this embodiment, the separation distance D between the extension portion 12 and the extension mating portion 22 is 3 mm.

[0115] This setting has the best effect of reducing the contact noise between the wire mesh cover and the top cover plate 2 and the best effect of preventing wear when no external force is applied.

[0116] Specifically, the extension portion 12 and the extension mating portion 22 are arranged in a fitting manner, and the fitting length L between the extension portion 12 and the extension mating portion 22 is not limited.

[0117] More specifically, the fitting length L between the extension portion 12 and the extension mating portion 22 satisfies: 30 mm ≤ L ≤ 40 mm.

[0118] This setting can ensure that when an external force is applied, the extension mating portion 22 generates an upward bearing force on the extension portion 12, increasing the strength of the wire mesh cover, preventing the wire mesh cover body 1 from deforming excessively and scraping against the wind blade, damaging the wind blade, and improving the installability.

[0119] Preferably, in this embodiment, the fitting length L between the extension portion 12 and the extension mating portion 22 is 35 mm.

[0120] This setting generates the maximum upward bearing force of the extension mating portion 22 on the extension portion 12 when an external force is applied, and has the best effect of increasing the strength of the wire mesh cover.

[0121] Specifically, as Figure 7 and Figure 12 shown, the extension portion 12 includes an extension body segment 121 and an inclined connection segment 122. One end of the inclined connection segment 122 is connected to the extension body segment 121, and the other end of the inclined connection segment 122 is connected to the wire mesh cover body 1.

[0122] This setting can ensure that the extension portion 12 and the extension mating portion 22 are separated when no external force is applied, reducing the contact noise between the wire mesh cover and the top cover plate 2 and preventing wear.

[0123] Specifically, the inclined connection segment 122 extends upward toward the wire mesh cover body 1 and away from the center plate 13 of the wire mesh cover body 1, and the angle α between the inclined connection segment 122 and the wire mesh cover body 1 satisfies: 147° ≤ α ≤ 153°.

[0124] This setting makes the separation distance between the extension part 12 and the extension mating part 22 appropriate when no external force is applied. On the one hand, it can ensure that the extension part 12 and the extension mating part 22 are separated when no external force is applied, and the effect of reducing the contact noise between the mesh cover and the top cover plate 2 is better, preventing wear. On the other hand, it can ensure that the strength of the mesh cover is better when an external force is applied.

[0125] Preferably, in this embodiment, as Figure 12 shown, the included angle α between the inclined connection section 122 and the mesh cover body 1 is 150°. This setting makes the separation distance between the extension part 12 and the extension mating part 22 the most appropriate when no external force is applied. On the one hand, it can further ensure that the extension part 12 and the extension mating part 22 are separated when no external force is applied, and the contact noise between the mesh cover and the top cover plate 2 is reduced best. On the other hand, it can ensure that the strength of the mesh cover is the best when an external force is applied.

[0126] Specifically, as Figure 11 and Figure 12 shown, the extension body section 121 and the mesh cover body 1 can be arranged in parallel, or the extension body section 121 and the mesh cover body 1 can be arranged obliquely, and no specific limitation is made.

[0127] Preferably, the extension body section 121 is arranged in parallel with the mesh cover body 1. This setting can ensure that when no external force is applied, the separation distance between the extension body section 121 and the extension mating part 22 is appropriate and equal everywhere, reducing the contact noise between the mesh cover body 1 and the top cover plate 2 and preventing wear.

[0128] Specifically, no specific limitation is made for the extension mating part 22. The extension mating part 22 is set as a groove or a protrusion, etc.

[0129] Preferably, in this embodiment, as Figure 7 shown, the extension mating part 22 is set as a groove.

[0130] This setting, firstly, can position and install the extension part 12, improving the installation efficiency; secondly, further increases the distance from the extension part 12, further reducing the contact noise between the mesh cover and the top cover plate 2 and preventing wear; thirdly, the groove plays a role in limiting the extension part 12, improving the strength of the installation structure.

[0131] Specifically, as Figure 9 and Figure 10 shown, the extension part 12 is arranged on the first strengthening structure 151.

[0132] This setting makes the stress points of the extension part 12 and the main rib 14 evenly distributed on the mesh cover body 1, further improving the strength of the installation structure.

[0133] Specifically, as Figure 8As shown, an air outlet hole 23 is provided on the top cover plate 2, and the mesh cover body 1 is matched with the air outlet hole 23.

[0134] In this embodiment, when the mesh cover body 1 and the top cover plate 2 are installed, first place the mesh cover body 1 on the air outlet hole 23, and then rotate the mesh cover body 1 so that the position of the extension portion 12 corresponds to the position of the extension mating portion 22, and make the position of the first mounting hole 11 correspond to the position of the second mounting hole 21; finally, fix the mesh cover body 1 on the top cover plate 2 through the connecting member 3 passing through the first mounting hole 11 and the second mounting hole 21.

[0135] For the mesh cover structure described in this embodiment, first, when no external force is applied, the extension portion 12 and the extension mating portion 22 are separated, reducing the contact noise between the mesh cover and the top cover plate 2 and preventing wear; second, when an external force is applied, the extension portion 12 and the extension mating portion 22 are in contact, and the extension mating portion 22 generates an upward bearing force on the extension portion 12, increasing the strength of the mesh cover, preventing the mesh cover from deforming excessively and rubbing against the fan blade, damaging the fan blade, and improving the installability; third, the arrangement of the extension portion 12 and the extension mating portion 22 reduces the use of the connecting member 3 and improves the installation efficiency.
