Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0024] Hereinafter, with reference to the accompanying drawings, an air conditioner 100 according to an embodiment of the present invention will be described.

[0025] refer to Figure 1 and Figure 2The air conditioner 100 includes an air outlet grille 10 for discharging air from the air conditioner 100. Along the airflow direction of the air outlet grille 10, the two sides of the air outlet grille 10 are an inner side and an outer side, respectively. The air outlet grille 10 includes a grille body 10a and a decorative layer 10b, with the decorative layer 10b disposed on the outer surface of the grille body 10a. The inner side of the air outlet grille 10 is the upstream side in the airflow direction, and the outer side is the downstream side. It is worth noting that when the air outlet grille 10 is composed of multiple grille bars, the outer surface of the grille body 10a may consist only of the outer surfaces of some outwardly protruding grille bars, without the decorative layer 10b on the remaining grille bars. However, this is not limited to this; alternatively, the outer surfaces of each grille bar may be coplanar, collectively forming the outer surface of the grille body 10a, with the decorative layer 10b disposed on the outer surface of each grille bar. It is noteworthy that, due to the thinness of the decorative layer 10b, it is shown as overlapping with the outer surface of the grille body 10a in the accompanying drawings.

[0026] The decorative layer 10b can be a layered structure with certain functions and / or decorations, disposed on the outer surface of the grille body 10a. The material of the decorative layer 10b is not limited; for example, the material of the decorative layer 10b can be plastic, metal, etc. The way in which the decorative layer 10b is disposed on the outer surface of the grille body 10a is not limited; for example, the decorative layer 10b can be combined with the outer surface of the grille body 10a by spraying, electroplating, vapor deposition, pasting, bonding, hot pressing, magnetic attraction, hot foil stamping, screen printing, offset printing, etc. Of course, the decorative layer 10b can be a single layered structure or a composite layered structure. The setting of the decorative layer 10b can make the air outlet grille 10 have different colors, textures, or patterns, achieving a multi-layered visual effect, while avoiding the decorative layer 10b covering the grille holes 1a, making the overall appearance of the air conditioner 100 more beautiful. Furthermore, by selecting the material of the decorative layer 10b, the weather resistance (such as UV resistance and temperature difference resistance) and corrosion resistance of the outer surface of the air outlet grille 10 can be enhanced.

[0027] refer to Figure 1 and Figure 2The length direction of the air conditioner 100 and the length direction of the air outlet grille 10 are both vertical. The air outlet grille 10 is located at the center of the front side of the air conditioner 100. The ratio of the width W1 of the air outlet grille 10 to the width W2 of the air conditioner 100 is 0.5-0.9, and the ratio of the length L1 of the air outlet grille 10 to the length L2 of the air conditioner 100 is 0.5-0.9. The grille body 10a is a one-piece molded part. For example, the ratio of the width W1 of the air outlet grille 10 to the width W2 of the air conditioner 100 can be 0.5, 0.6, 0.7, 0.8, or 0.9, etc., and the ratio of the length L1 of the air outlet grille 10 to the length L2 of the air conditioner 100 can be 0.5, 0.6, 0.7, 0.8, or 0.9, etc. Therefore, the air outlet grille 10 occupies a large portion of the overall size of the air conditioner 100, and has a large effective air outlet area. The air can be discharged more smoothly and in larger quantities through the air outlet grille 10, thereby improving the air outlet efficiency of the air conditioner 100. It can adjust the indoor temperature more quickly and improve the user's comfort. At the same time, it makes the air outlet of the air conditioner 100 softer, improving the uniformity and coverage of the air supply. The air outlet grille 10 is located in the center of the front side of the air conditioner 100 and is aligned with the air conditioner 100 in the longitudinal direction. The air outlet grille 10 occupies a large portion of the overall size of the air conditioner 100. This symmetrical and regular layout makes the overall appearance of the air conditioner 100 more harmonious and beautiful.

[0028] The method of integral molding of the grille body 10a is not limited. For example, it can be injection molding, die casting, etc. For example, the air outlet grille 10 includes a first grille bar 1 and a second grille bar 2. When the air outlet grille 10 is made of non-metallic material, the integral connection of the first grille bar 1 and the second grille bar 2 can be achieved by injection molding. For example, the first grille bar 1 and the second grille bar 2 can be integrally injection molded, or one can be processed first and then the other can be processed by embedding injection molding to achieve the integral connection of the first grille bar 1 and the second grille bar 2. The integral connection makes the overall structural strength of the air outlet grille 10 more stable and less prone to deformation.

[0029] In the above technical solution, by setting an air outlet grille at the air outlet position of the air conditioner, the opening and closing door can be eliminated under normal circumstances, simplifying the structure and reducing costs. The grille body 10a is a one-piece molded part, which makes the overall structure of the air outlet grille 10 more stable, facilitates production and assembly, improves production efficiency, reduces assembly gaps and stress concentration problems that may occur when assembling multiple parts, and enhances the structural strength of the air outlet grille 10, making it less prone to deformation and damage, and extending the service life of the air outlet grille 10. The air outlet grille 10 occupies a large overall size of the air conditioner 100, and a decorative layer 10b is set on the outer surface of the grille body 10a. The air outlet grille 10 has a large effective air outlet area, which improves the air outlet efficiency of the air conditioner 100, and makes the air outlet of the air conditioner 100 softer, improving the uniformity and coverage of the air supply. The air outlet grille 10 is located in the center of the front side of the air conditioner 100, making the overall appearance of the air conditioner 100 more coordinated and beautiful.

[0030] refer to Figure 3 In some embodiments, the air conditioner 100 includes a duct component 40 and a panel component 20. The duct component 40 includes a duct 401 and a fan wheel 402. The fan wheel 402 is disposed in the duct 401 and is a cross-flow fan wheel 402 whose axis extends in the vertical direction. The panel component 20 has an air outlet 71 communicating with the duct 401. An air outlet grille 10 is disposed at the air outlet 71, and the ratio of the width W3 of the air outlet 71 to the diameter W4 of the cross-flow fan wheel 402 is 1.5-3. For example, the ratio of the width W3 of the air outlet 71 to the diameter W4 of the cross-flow fan wheel 402 can be 1.5, 2, 2.5, or 3, etc.

[0031] In the above technical solution, the ratio of the width W3 of the air outlet 71 to the diameter W4 of the cross-flow fan 402 is 1.5-3, which allows the airflow to diffuse more smoothly when it enters the air outlet 71 from the cross-flow fan 402. As a result, the airflow distribution at the air outlet 71 is relatively uniform, reducing the noise caused by turbulence and collision at the air outlet 71. It also avoids the problems of concentrated airflow and uneven airflow caused by the air outlet 71 being too small, or the airflow being too dispersed and weakened by the air outlet 71 being too large, thus providing users with a more comfortable air supply experience. In addition, the cross-flow fan 402 has a high air outlet efficiency, which allows the air conditioner 100 to reach the set temperature more quickly.

[0032] refer to Figure 2 In some embodiments, the ratio of the length L of the air vent grille 10 to the width M of the air vent grille 10 is 3-10. For example, the ratio of the length L of the air vent grille 10 to the width M of the air vent grille 10 can be 3, 4, 5, 6, 7, 8, 9, 10, etc.

[0033] In the above technical solution, the ratio of the length L of the air outlet grille 10 to the width M of the air outlet grille 10 is 3-10, and the length direction of the air conditioner 100 and the length direction of the air outlet grille 10 are the same, both being vertical, which can improve the vertical air outlet range of the air conditioner 100.

[0034] refer to Figure 4 and Figure 5 In some embodiments, the air outlet grille 10 includes a first grille 1 and a second grille 2. The length direction of the first grille 1 extends in the vertical direction and there are multiple grilles spaced apart in the width direction of the air outlet grille 10. The second grille 2 intersects with the first grille 1 to form a grille hole 1a between the first grille 1 and the second grille 2. There are multiple second grilles 2 and they are spaced apart in the vertical direction. The outer surface 1c of the first grille 1 protrudes outward relative to the outer surface 2c of the second grille 2. The outer surface 1c of the first grille 1 forms the outer surface of the grille body 10a. A decorative layer 10b is disposed on the outer surface 1c of the first grille 1. At least a portion of the inner surface 2d of at least one second grille 2 protrudes inward relative to the inner surface 1d of the first grille 1.

[0035] The form in which the first grille 1 and the second grille 2 intersect is not limited. For example, the first grille 1 can be located on the outside of the air outlet grille 10 and the second grille 2 can be located on the inside. The first grille 1 and the second grille 2 can contact and be fixedly connected at the intersection point. Alternatively, one of the first grille 1 and the second grille 2 can be completely embedded in the other to form an integrated structure, thereby improving the overall structural strength and surface flatness.

[0036] In the above technical solution, the outer surface 1c of the first grille 1 is set to protrude further outward than the outer surface 2c of the second grille 2. That is, the first grille 1 is closer to the user side, which makes it easier to process the decorative layer 10b only on the outer surface 1c of the first grille 1. This allows the overall visual shape of the air outlet grille 10 to be dominated by the first grille 1, and the extension direction of the first grille 1 is consistent with the length direction of the main body of the air conditioner 100, thereby forming a sense of vertical visual extension and enhancing the vertical stretching visual effect of the space. At the same time, since the decorative layer 10b is only provided on the outer surface 1c of the protruding first grille 1, the processing cost is low and it is easy to achieve a variety of appearances, such as high gloss, brushed or imitation metal texture, to enhance the texture of the air conditioner 100. The protruding part of the inner surface of the second grille 2 increases the structural strength of the second grille 2 and improves the reliability of supporting the first grille 1.

[0037] refer to Figure 5 , Figure 6 and Figure 7In some embodiments, the dimension of the first grid bar 1 along its own airflow direction is the width of the first grid bar 1, and at least one first grid bar 1 is a widened grid bar 12, which widens inward at the junction P with the second grid bar 2. Exemplarily, the widened grid bar 12 includes a widened section 1211, which widens inward at the junction P with the second grid bar 2. The junction P refers to the position where the two grid bars intersect, or nearby, that is, close to the intersection of the two grid bars.

[0038] In the above technical solution, at least one first grille 1 is a widened grille 12. The widened grille 12 makes the first grille 1 have higher structural strength at the junction P with the second grille 2, thereby improving the overall structural strength and deformation resistance of the air outlet grille 10. The widened grille 12 is widened inward at the junction P with the second grille 2, which can enhance the structural connection strength, while not affecting the overall external visual effect of the air outlet grille 10, and reducing the damage of the widened grille 12 to the appearance.

[0039] refer to Figure 5 , Figure 6 and Figure 7 In some embodiments, the dimension of the second grid bar 2 along its own airflow direction is the width of the second grid bar 2. At least two second grid bars 2 have different widths. At least one second grid bar 2 is a narrow grid bar 22, and at least one second grid bar 2 is a wide grid bar 21. The maximum width G2 of the wide grid bar 21 is greater than the maximum width G1 of the narrow grid bar 22.

[0040] In the above technical solution, the second grid bar 2 includes a narrow grid bar 22 and a wide grid bar 21, which allows for differentiated design based on actual air outlet requirements and structural strength requirements. The wide grid bar 21 can mainly bear the main structural load to enhance the overall structural strength, while the narrow grid bar 22 is mainly used to reduce the overall weight of the air outlet grille 10 and guide the air outlet to optimize airflow distribution and reduce wind resistance. By rationally arranging the position and number of the wide grid bar 21 and the narrow grid bar 22, the material consumption of the air outlet grille 10 can be effectively reduced while maintaining the structural strength of the air outlet grille 10, further reducing manufacturing costs.

[0041] refer to Figure 8 and Figure 9 In some embodiments, the length direction of the second grid bar 2 is horizontal, and at least one second grid bar 2 is a guide horizontal grid bar 23, combined with Figure 10 and Figure 11At least one of the upper and lower surfaces of the air guide bar 23 is configured as an air guide surface 231. The air guide surface 231 is inclined upward or downward relative to the horizontal surface in the direction from the inside to the outside. The air outlet grille 10 is divided into two parts above and below the dividing line S1 by the dividing line S1. At least one air guide bar 23 is provided above and below the dividing line S1 respectively. The air guide surface 231 of the air guide bar 23 above the dividing line S1 is inclined upward relative to the horizontal surface in the direction from the inside to the outside. The air guide surface 231 of the air guide bar 23 below the dividing line S1 is inclined downward relative to the horizontal surface in the direction from the inside to the outside.

[0042] Among them, the air guide surface 231 is the surface on the air guide horizontal bar 23 that directly contacts the airflow and guides its flow. The upper surface and the lower surface of the air guide horizontal bar 23 can be constructed as the air guide surface 231, or both the upper surface and the lower surface can be constructed as the air guide surface 231 to guide the airflow to flow in a direction that is inclined upward or downward relative to the horizontal surface.

[0043] For example, the air guide surface 231 of the air guide bar 23 above the dividing line S1 can gradually increase in the upward angle relative to the horizontal plane along the direction from the inside to the outside. That is, the inclination angle b2 of the air guide bar 23 is greater than b1. Similarly, the air guide surface 231 of the air guide bar 23 below the dividing line S1 can gradually increase in the downward angle relative to the horizontal plane along the direction from the inside to the outside. That is, the inclination angle h1 of the air guide bar 23 is greater than h2. Thus, the gradient design of the inclination angle of the air guide surface 231 in the upper and lower sections enables the airflow to form a multi-layered diffusion in the vertical direction, effectively reducing the direct blowing sensation caused by concentrated airflow and improving the uniformity and comfort of air delivery.

[0044] In the above technical solution, the air guide bar 23 not only serves as a structural support but also functions as an air guide. Its inclined air guide surface 231 guides the airflow, allowing for vertical adjustment of the air outlet angle and improving the practicality of the air conditioner 100. By dividing the air outlet grille 10 into upper and lower sections, and tilting the upper air guide bar 23's air guide surface 231 upwards and the lower air guide bar 23's air guide surface 231 downwards, the vertical airflow range of the air conditioner 100 is expanded, resulting in more uniform indoor air circulation and improved uniformity of indoor air conditioning. Because the air guide surface 231 of the air guide bar 23 is tilted, the airflow will not directly impact surrounding objects or people when exiting the grille, thus reducing the discomfort caused by direct cold air and lowering noise generated by airflow disturbance.

[0045] refer to Figure 12In some embodiments, the length direction of the second grid bar 2 is horizontal, and the ratio of the spacing M2 between two adjacent second grid bars 2 to the spacing M1 between two adjacent first grid bars 1 is greater than or equal to 2. Figure 13 The decorative layer 10b is located on a plane S1, at which point the outer surface 1c of the first grid bar 1 is located in the same plane; or refer to Figure 4 The decorative layer 10b is located on a cylindrical surface S2, the axis of which extends along the length direction Z of the air outlet grille 10. At this time, the outer surface 1c of the first grille 1 is located within the same cylindrical surface. The decorative layer 10b is located on a plane S1. The structure of the air outlet grille 10 is relatively simple, which can reduce the manufacturing difficulty. The decorative layer 10b is located on a cylindrical surface S2, which can adapt to the curved appearance of the air conditioner 100, increase the air outlet range and angle, and make the air outlet grille 10 match the curvature of the air conditioner 100 casing.

[0046] In the above technical solution, the ratio of the distance M2 between two adjacent second grilles 2 to the distance M1 between two adjacent first grilles 1 is greater than or equal to 2. That is, the second grilles 2 are arranged more sparsely and the first grilles 1 are arranged more densely. In addition, the length direction of the first grilles 1 extends in the vertical direction, and a decorative layer 10b is provided on the outer surface 1c of the first grilles 1. As a result, the user will notice the first grilles 1 first, so that the overall visual shape of the air vent grille 10 can be dominated by the first grilles 1, thereby forming a sense of vertical visual extension and enhancing the vertical stretching visual effect of the space.

[0047] refer to Figure 14 In some embodiments, the air conditioner 100 includes a panel component 20, which has an air outlet 71. An air outlet grille 10 is disposed at the air outlet 71 and is detachably mounted on the panel component 20. A buffer member 50 is provided between the air outlet grille 10 and the panel component 20.

[0048] The detachable installation method of the air outlet grille 10 and the panel component 20 is not limited, such as screw connection, snap-on connection, magnetic connection, etc. The placement of the buffer 50 is not limited; it can be placed on the air outlet grille 10, on the panel component 20, or it can be a separate component clamped between the air outlet grille 10 and the panel component 20. The material of the buffer 50 is not limited; for example, it can be silicone, rubber sponge, or foam material.

[0049] In the above technical solution, the air outlet grille 10 is detachably installed on the panel component 20, allowing users or maintenance personnel to easily remove the air outlet grille 10 from the air conditioner 100, thereby facilitating daily maintenance and improving cleaning efficiency and maintenance convenience. A buffer component 50 is provided between the air outlet grille 10 and the panel component 20, which can effectively absorb and buffer the vibration generated during the operation of the air conditioner 100. This reduces the transmission of vibration to the air outlet grille 10, thereby reducing the noise of the air conditioner 100 during transportation and operation. Furthermore, the buffer component 50 can prevent direct collision and friction between the air outlet grille 10 and the panel component 20, reducing wear and damage to the components, extending the service life of the air outlet grille 10 and the panel component 20, and reducing maintenance and replacement costs.

[0050] refer to Figures 14-18 In some embodiments, the air outlet grille 10 includes a first grille 1, an upper frame 3c, and a lower frame 3d. The length direction of the first grille 1 extends in the vertical direction and there are multiple grilles spaced apart along the width direction of the air outlet grille 10. The upper frame 3c is located at the upper end of the air outlet grille 10 and extends along the width direction of the air outlet grille 10, and is connected to the upper ends of the multiple first grilles 1. The outer surface of the upper end of the first grille 1 protrudes outward relative to the outer surface of the upper frame 3c. The lower frame 3d is located at the lower end of the air outlet grille 10 and extends along the width direction of the air outlet grille 10, and is connected to the lower ends of the multiple first grilles 1. The outer surface of the lower end of the first grille 1 protrudes outward relative to the outer surface of the lower frame 3d. The buffer member 50 is provided on the inner surface of the upper frame 3c and / or on the inner surface of the lower frame 3d. That is, the buffer 50 can be provided on the inner surface of the upper frame 3c alone or on the inner surface of the lower frame 3d alone, or the buffer 50 can be provided on both the inner surface of the upper frame 3c and the inner surface of the lower frame 3d.

[0051] In the above technical solution, the outer surfaces of the upper and lower ends of the first grille 1 protrude from the upper frame 3c and the lower frame 3d, which facilitates the setting of the decorative layer 10b on the outer surface 1c of the first grille 1. The decorative layer 10b is not processed onto the upper frame 3c and the lower frame 3d, thus visually creating a frameless effect for the air outlet grille 10, increasing the three-dimensionality of the air outlet grille 10, and making the appearance of the air outlet grille 10 more beautiful and elegant. The buffer 50 is set on the inner surface of the upper frame 3c and the lower frame 3d, which facilitates the fixing and installation of the buffer 50. At the same time, the buffer 50 can absorb and buffer the vibration generated during the operation of the air conditioner, effectively absorbing and buffering the vibration generated during the operation of the air conditioner 100, reducing the vibration transmitted to the air outlet grille 10, thereby reducing the noise of the air conditioner 100 during operation.

[0052] refer to Figures 14-18 In some embodiments, the buffer 50 includes a protrusion 501 integrally formed on the air vent grille 10.

[0053] In the above technical solution, the protrusion 501 is integrally formed with the air outlet grille 10. Compared with setting the protrusion 501 on the panel component 20, the manufacturing difficulty can be reduced. The integrally formed protrusion 501 is set on the inner surface of the upper frame 3c or the lower frame 3d, which will not affect the aesthetic appearance of the air outlet grille 10, making the air conditioner look cleaner and more elegant.

[0054] refer to Figure 18 In some embodiments, the buffer 50 includes a rubber pad 502 fitted between the panel component 20 and the air vent grille 10.

[0055] In the above technical solution, the rubber pad 502 has good elasticity and flexibility, which can provide more effective cushioning and shock absorption. When the rubber pad 502 is worn or aged due to long-term use, it can be easily replaced, thus extending the service life of the air conditioner.

[0056] refer to Figures 14-18 In some embodiments, the buffer 50 includes a protrusion 501 integrally formed on the air vent grille 10; the buffer 50 includes a rubber pad 502 fitted between the panel component 20 and the air vent grille 10.

[0057] In the above technical solution, the buffer 50 includes a protrusion 501 and a rubber pad 502. The rubber pad 502 can reduce wear. However, the rubber pad 502 may break or fall off during continuous wear. The protrusion 501 can still maintain a certain buffering function even when the rubber pad 502 is worn and its function is weakened. This avoids direct hard contact between the air outlet grille 10 and the panel component 20, effectively extending the structural life.

[0058] In some embodiments, the decorative layer 10b includes at least one of the following: a hot stamping foil layer, a heat transfer layer, a UV screen printing layer, a UV oil layer, a vacuum evaporation layer, a screen printing color layer, and an offset printing layer. That is, the decorative layer 10b can be a single-layer structure or a multi-layer composite structure, achieving rich visual effects and textures through different process combinations.

[0059] Hot stamping is a decorative printing technique that transfers foil (such as metallic foil or colored foil) to the surface of a substrate using heat and pressure. The foil layer can be made of metallic or non-metallic materials. Metallic foils are primarily composed of metals (aluminum, copper, etc.), and the metal layer is deposited onto a base film via vacuum evaporation. Common examples include gold foil, silver foil, and copper foil, which produce a pure metallic luster. Non-metallic foils do not contain metallic components and rely on coatings to achieve decorative effects. These include colored foils (solid color, gradient, pearlescent coatings), holographic foils (laser coatings with D / iridescent effects), and matte foils (frosted coatings), thus achieving a metallic or special texture (including matte, frosted, brushed, pearlescent, fluorescent, etc.). Depending on the form of the outer surface 1c of the first grid strip 1 (e.g., flat or cylindrical), hot stamping techniques such as flat stamping, roll stamping, and cold stamping can be used to place the foil layer on the outer surface of the first grid strip 1, achieving overall visual unity or local embellishment effects.

[0060] For example, the decorative layer 10b can be a heat transfer layer, which utilizes the metal coating on the heat transfer film to be transferred to the outer surface 1c of the first grid bar 1 by hot pressing.

[0061] For example, the decorative layer 10b can be a UV screen printing layer, in which UV ink containing a photosensitive agent is transferred to the outer surface 1c of the first grid 1 by screen printing technology, and then cured by ultraviolet light to form a coating with special visual effects and functions.

[0062] For example, the decorative layer 10b can be a UV oil layer, which forms a high-gloss or matte protective layer on the outer surface 1c of the first grid 1 through a UV curing process.

[0063] For example, the decorative layer 10b can be a vacuum evaporation layer, in which metal or non-metal materials are evaporated and adhered to the surface of the first grid 1 in a high vacuum environment using physical vapor deposition technology to form a dense and uniform decorative film layer. Alternatively, the decorative layer 10b can be a screen-printed color layer, in which different colored inks are superimposed through multiple screen printing processes to transfer the pattern to the outer surface 1c of the first grid 1.

[0064] For example, the decorative layer 10b can be an offset printing layer, in which the pattern is directly printed onto the outer surface 1c of the first grid 1 using an offset printing process.

[0065] In the above technical solution, the decorative layer 10b can be any combination of the above processes to form a multi-layer composite structure, so as to achieve more complex patterns, color gradients and three-dimensional textures, and improve the weather resistance, wear resistance and adhesion of the decorative layer 10b. For example, a metallic base color can be formed by vacuum evaporation first, and then UV screen printing can be combined to achieve local high-gloss patterns, etc., to achieve a multi-layered and multi-process synergistic decorative effect, making the product appearance more layered and technological.

[0066] In some embodiments, decorative layer 10b is a hot stamping layer, wherein the hot stamping layer is a foil layer made of metal foil and / or a metal-effect layer.

[0067] Among them, the imitation metal effect layer is a decorative layer 10b that is processed by physical or chemical processes to make the surface of non-metallic or metallic substrates present a similar metallic luster, texture and color. The imitation metal effect means that the decorative layer 10b has the characteristics of strong reflectivity (having the "mirror reflection" or "soft metallic reflection" unique to metal) and heavy texture.

[0068] It's worth noting that achieving a metallic effect with hot stamping doesn't necessarily require metal foil. Metal foil, non-metal foil, or other auxiliary processes can all be used. For example, non-metal foil (metallic coating) can simulate metallic luster by adding metallic pigments (such as aluminum or copper powder) to the foil coating. Other auxiliary processes can also be employed, such as applying a layer of high-gloss UV varnish after hot stamping on non-metal foil, which enhances the gloss of the metallic finish and further replicates the texture of metal foil.

[0069] In the above technical solution, the decorative layer 10b is a hot-stamping layer, which can increase the gloss of the outer surface of the air vent grille 10, giving it a metallic texture and enhancing its visual appeal, thereby improving the user experience. The air vent grille 10 can be manufactured using non-technical materials, thus reducing its production cost. Simultaneously, the hot-stamping layer effectively resists scratches and environmental aging during daily use, and also enhances the weather resistance (such as UV resistance and temperature difference resistance) and corrosion resistance of the outer surface of the air vent grille 10.

[0070] In some embodiments, the grille body 10a is a one-piece injection-molded plastic part, thereby reducing costs and weight. For example, the grille body 10a is a one-piece injection-molded plastic part, and a decorative layer 10b is provided, thereby achieving the desired aesthetic effect while reducing costs.
