Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically providing a fan and its mesh assembly. Background Technology

[0002] In the current home appliance market, air circulation fans typically integrate aromatherapy functions to enhance the user experience. This function is achieved by installing a removable aromatherapy cover on the front grille.

[0003] In existing technologies, most air circulation fans use a snap-fit ​​structure to connect the front grille and the aromatherapy cover, with the aromatherapy tablet positioned between them. This allows the airflow generated by the fan to carry the fragrance from the tablet outwards. However, after prolonged use, the existing snap-fit ​​structure is prone to loosening due to material aging. This loosening can further cause the aromatherapy cover to resonate and generate abnormal noise during fan operation, affecting not only the normal operation of the product but also reducing the overall user experience. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the existing aromatherapy lid is easy to loosen, thereby causing resonance and abnormal noise.

[0006] In some feasible embodiments of the fan grille assembly described above, the first connection includes a cantilever structure extending circumferentially along the front grille to make the first connection elastic.

[0007] In some feasible embodiments of the fan grille assembly described above, the first connecting part is provided with a first snap-fit ​​structure, the cantilever structure is formed on the first snap-fit ​​structure, the second connecting part is provided with a second snap-fit ​​structure, and the first snap-fit ​​structure snaps into the second snap-fit ​​structure.

[0008] In some feasible embodiments of the fan grille assembly described above, the cantilever structure is provided with a protrusion extending axially along the front grille, and the second connecting portion is provided with a groove adapted to the protrusion, so that the aromatherapy cap and the front grille are circumferentially limited by the cooperation of the protrusion and the groove.

[0009] In some feasible embodiments of the fan grille assembly described above, the first snap-fit ​​structure is a gradient snap-fit ​​hole structure extending circumferentially along the front grille, the cantilever structure is formed on the side of the snap-fit ​​hole structure with a reduced hole size, the second snap-fit ​​structure is a snap-on structure extending axially along the aroma diffuser cover, the groove is formed on the snap-on structure, and the snap-on structure can pass through the snap-fit ​​hole structure and rotate to snap into the snap-fit ​​hole structure.

[0010] In some feasible embodiments of the fan grille assembly described above, the front grille is provided with a mounting portion, the first connecting portion is formed on the mounting portion, and at least a portion of the thickness of the cantilever structure is less than the thickness of the mounting portion to which it is connected.

[0011] In some feasible embodiments of the fan cover assembly described above, the inner side of the ring wall of the aroma diffuser cover is provided with a plurality of inwardly protruding fixing protrusions to fix the aroma diffuser tablet.

[0012] In some feasible embodiments of the fan grille assembly described above, the fixing protrusion is formed on the second connecting portion.

[0013] In some feasible embodiments of the fan grille assembly described above, the aromatherapy cap snaps onto the front or rear side of the front grille.

[0014] The technical solution provided by this utility model, through structural improvement, makes the first connecting part of the front mesh cover elastic, allowing it to cooperate with the second connecting part of the aromatherapy cap for a detachable connection. This utility model effectively solves the problem of existing aromatherapy caps being prone to loosening, leading to resonance and abnormal noise. Specifically, when the first connecting part and the second connecting part are connected to each other, the first connecting part can rely on the rebound force generated by its own deformation to tightly connect with the second connecting part, improving the installation stability and connection reliability of the aromatherapy cap on the front mesh cover, thereby avoiding the resonance and abnormal noise problems caused by the aromatherapy cap being loose.

[0015] Furthermore, this invention achieves circumferential positioning of the aromatherapy cap and the front mesh cover through the cooperation of the protrusion and the groove. This circumferential positioning structure prevents the aromatherapy cap from rotating circumferentially due to vibrations generated by the fan after installation, thereby reducing the risk of loosening caused by relative displacement between components. In addition, the rebound force of the cantilever structure allows for a further increase in the height of the protrusion and the depth of the groove, making it less prone to disengagement after engagement, thus improving the vibration resistance of the connected structure and avoiding disengagement caused by resonance and the resulting abnormal noise. This invention not only significantly improves the stability and reliability of the aromatherapy cap installation, ensuring the product's quiet performance during long-term use, but also enhances the durability of the connection structure, while providing users with a more stable and quiet user experience.

If a dependency and / or order is required, it will be explicitly stated in the context, or it will be obvious to those skilled in the art when understanding the specific embodiments.

[0023] To address the problem that existing aromatherapy diffuser covers are prone to loosening, leading to resonance and abnormal noise, this utility model provides a fan mesh assembly.

[0024] Example 1 This utility model embodiment provides a fan grille assembly, such as... Figure 1 and Figure 2As shown, the mesh cover assembly includes a front mesh cover 100, an aromatherapy sheet 300, an aromatherapy cap 200, and a rear mesh cover (not shown). The front mesh cover 100 and the rear mesh cover are connected to form a space for accommodating the fan blades (not shown). The aromatherapy cap 200 is snapped onto the front side of the front mesh cover 100. The aromatherapy sheet 300 is located between the aromatherapy cap 200 and the front mesh cover 100 and is situated inside the aromatherapy cap 200. The aromatherapy sheet 300 is a thin sheet capable of absorbing aromatherapy liquid or essential oil. It is understood that the shape and thickness of the aromatherapy sheet 300 are not limited in this invention.

[0025] like Figure 3 As shown, the front mesh cover 100 is roughly disc-shaped. The front mesh cover 100 includes a mesh cover portion 130 and a mounting portion 120. The mesh cover portion 130 constitutes the main body of the front mesh cover 100 and has multiple mesh structures (not shown) for airflow. A third connecting portion 140 is provided on the radially outer side of the mesh cover portion 130, specifically formed on the mesh cover portion 130. The front mesh cover 100 is connected to the rear mesh cover of the mesh cover assembly via the third connecting portion 140. The mounting portion 120 is located in the middle of the mesh cover portion 130 and is used to correspond with the aromatherapy cap 200. The mounting portion 120 has multiple vent holes 121 for airflow, thereby diffusing the fragrance of the aromatherapy tablet 300 outwards. The mounting portion 120 and the mesh cover portion 130 can be integrally formed or connected as a single structure by means of bonding or other methods.

[0026] like Figures 4 to 7 As shown, the front mesh cover 100 is provided with a first connecting portion 110 that is detachably connected to the second connecting portion 210 of the aromatherapy cover 200. The aromatherapy cover 200 and the front mesh cover 100 are detachably connected through the cooperation of the second connecting portion 210 and the first connecting portion 110. The first connecting portion 110 is provided with a first snap-fit ​​structure for snapping with the second snap-fit ​​structure of the second connecting portion 210. The first connecting portion 110 includes a cantilever structure 112 extending circumferentially along the front mesh cover 100 to make the first connecting portion 110 elastic. The cantilever structure 112 is formed on the first snap-fit ​​structure.

[0027] It should be noted that the number of first connecting parts 110 should at least match the number of second connecting parts 210 of the aroma diffuser lid 200. That is, if the number of second connecting parts 210 of the aroma diffuser lid 200 is three, the number of first connecting parts 110 should be at least three. However, the number of first connecting parts 110 is not limited to the three shown in the figure; it can be two, four, five, etc. The specific number can be designed and adjusted according to the number of second connecting parts 210 of the aroma diffuser lid 200.

[0028] Furthermore, the first connecting portion 110 is formed on the mounting portion 120, and at least a portion of the cantilever structure 112 has a thickness less than the thickness of the mounting portion 120 to which it is connected. Specifically, as shown... Figure 7 As shown, the thickness d of the entire cantilever structure 112 is less than the thickness D of the mounting portion 120. This design effectively improves the elastic deformation capability of the cantilever structure 112.

[0029] Further reference Figures 4 to 7 The first snap-fit ​​structure is specifically a gradually tapered snap-fit ​​structure 111 extending circumferentially along the front mesh cover 100. The snap-fit ​​structure 111 is used for the snap-fit ​​structure 211 of the second connecting part 210 to pass through and be rotatably snapped with the snap-fit ​​structure 211. Specifically, the first side 1111 of the snap-fit ​​structure 111 has an enlarged hole size, and the second side 1112 of the snap-fit ​​structure 111 has a reduced hole size. The cantilever structure 112 is formed on the reduced hole size side (second side 1112). Specifically, in this embodiment of the invention, the hole size of the snap-fit ​​structure 111 is the radial width of the snap-fit ​​structure 111.

[0030] Further reference Figures 4 to 7 The rear side of the cantilever structure 112 is provided with a protrusion 113 extending rearward along the axial direction of the front mesh cover 100. The protrusion 113 is adapted to the groove 212 of the second connecting part 210, so that the aromatherapy cover 200 and the front mesh cover 100 are circumferentially limited by the cooperation of the protrusion 113 and the groove 212.

[0031] like Figure 8 As shown, the aromatherapy cap 200 is roughly cylindrical in shape. The outer edge of the aromatherapy cap 200 extends rearward along its axial direction to form an annular wall 240, creating a space on the rear side of the aromatherapy cap 200 for accommodating the aromatherapy tablet 300. A circumferentially arranged anti-slip portion is provided on the radially outer side of the aromatherapy cap 200 to increase friction on its outer edge, facilitating screwing. The aromatherapy cap 200 has a second connecting portion 210 that is detachably connected to the first connecting portion 110 of the front mesh cover 100. The aromatherapy cap 200 and the front mesh cover 100 are detachably connected through the cooperation of the second connecting portion 210 and the first connecting portion 110. The second connecting portion 210 is located on the rear side of the aromatherapy cap 200 and extends rearward along its axial direction, with the extension length of the second connecting portion 210 greater than the extension length of the annular wall 240.

[0032] It should be noted that the number of second connecting parts 210 is at least matched with the number of first connecting parts 110 of the front mesh cover 100. That is, if the number of first connecting parts 110 of the front mesh cover 100 is three, the number of second connecting parts 210 is at least three. However, the number of second connecting parts 210 is not limited to the three shown in the figure, and can be two, four, five, etc. The specific number can be designed and adjusted according to the number of first connecting parts 110 of the front mesh cover 100.

[0033] Furthermore, a plurality of fixing protrusions 220 protruding radially inward along the aroma diffuser cover 200 are provided on the inner side of the annular wall 240 to fix the aroma diffuser sheet 300. The fixing protrusions 220 are specifically formed on the second connecting portion 210. With the above arrangement, the aroma diffuser sheet 300 can be fixed to the inner side of the aroma diffuser cover 200.

[0034] It should be noted that the number of fixed protrusions 220 is not limited to the three shown in the figure. It can be two, four, five, etc. The specific number can be designed and adjusted according to the number of the second connecting parts 210 of the front mesh cover 100.

[0035] like Figures 9 to 10 As shown, the second connecting portion 210 is provided with a second snap-fit ​​structure for engaging with the first snap-fit ​​structure. The second snap-fit ​​structure is a snap-fit ​​structure 211 extending axially along the aroma diffuser cover 200. The snap-fit ​​structure 211 can pass through the snap-fit ​​hole structure 111 and rotatably engage with it. Specifically, the snap-fit ​​structure 211 includes an extension portion 2111 and a mating portion 2112. The extension portion 2111 extends rearward along the axial direction of the aroma diffuser cover 200, and the mating portion 2112 is located at the end of the snap-fit ​​structure 211 and protrudes radially inward along the aroma diffuser cover 200. The mating portion 2112 corresponds to the cantilever structure 112. Specifically, the radial width of the mating portion 2112 is smaller than the radial width of the first side 1111 of the snap-fit ​​hole structure 111, so that the mating portion 2112 can pass through the first side 1111 of the snap-fit ​​hole structure 111. The radial width of the extension 2111 is slightly larger than the radial width of the second side 1112 of the snap hole structure 111, so that the extension 2111 can be interference-fitted with the second side 1112 of the snap hole structure 111.

[0036] Further reference Figures 9 to 10 The second connecting portion 210 is provided with a groove 212 that is recessed rearward along the axial direction of the aroma diffuser cover 200. This groove 212 is adapted to the protrusion 113 of the first connecting portion 110 so that the aroma diffuser cover 200 and the front mesh cover 100 are circumferentially limited by the cooperation of the protrusion 113 and the groove 212. The groove 212 is specifically formed on the front side of the mating portion 2112 of the snap-fit ​​structure 211.

[0037] It should be noted that the elasticity of the cantilever structure 112 in this embodiment of the present invention provides greater flexibility for the size design of the protrusion 113 (height) and the groove 212 (depth). Specifically, without a corresponding elastic structure (cantilever structure 112), the dimensions of the protrusion 113 and the groove 212 need to be designed to be small in order to achieve smooth engagement between them; otherwise, it would be difficult to engage during assembly. However, a small size would result in insufficient engagement depth and weak locking force, making it prone to disengagement under vibration, thus causing circumferential limiting failure. With the elastic cantilever structure 112, its elastic deformation capability allows the protrusion 113 and the groove 212 to adopt larger engagement dimensions. During assembly, the protrusion 113 can smoothly slide into the groove 212 using the elasticity of the cantilever structure 112. Therefore, the elastic cantilever structure 112 can increase the design dimensions of the protrusion 113 and the groove 212, thereby increasing the engagement depth and significantly reducing the risk of disengagement, effectively improving the stability and reliability of the aromatherapy cap 200 installation.

[0038] This embodiment of the invention achieves circumferential positioning of the aromatherapy cover 200 and the front mesh cover 100 through the cooperation of the protrusion 113 and the groove 212. This circumferential positioning structure prevents the aromatherapy cover 200 from rotating circumferentially due to vibrations generated by the fan operation after installation, thereby reducing the risk of loosening caused by relative displacement between components. Furthermore, the rebound force of the cantilever structure 112 allows for a further increase in the height of the protrusion 113 and the depth of the groove 212, making it less prone to disengagement after engagement. This enhances the vibration resistance of the connected structure, avoiding disengagement caused by resonance and the resulting abnormal noise. This embodiment of the invention not only significantly improves the stability and reliability of the aromatherapy cover 200 installation, ensuring quiet operation during long-term use, but also enhances the durability of the connection structure, providing users with a more stable and quiet user experience.

[0039] like Figures 11 to 14 As shown, the assembly process of attaching the aromatherapy cover 200 to the front side of the front mesh cover 100 in this embodiment of the present invention is as follows: First, place the aromatherapy cover 200 in front of the mounting portion 120 of the front mesh cover 100, so that the rear side of the aromatherapy cover 200 is opposite to the front side of the mounting portion 120 of the front mesh cover 100 (that is, the front side of the aromatherapy cover 200 and the rear side of the aromatherapy cover 200 face the same direction, and their axes are basically parallel, and align the snap-fit ​​structure 211 of the aromatherapy cover 200 with the first side 1111 of the snap-fit ​​structure 111. Then, as... Figure 11 and Figure 12 As shown, the snap-fit ​​structure 211 of the aroma diffuser cap 200 is passed rearward along its axial direction through the first side 1111 of the snap hole structure 111. After the snap-fit ​​structure 211 passes through the first side 1111 of the snap hole structure 111, as... Figure 13 and Figure 14 As shown, the aromatherapy cap 200 is rotated circumferentially to cause the snap-fit ​​structure 211 to slide into the second side 1112 of the snap-fit ​​structure 111, thereby causing the extension portion 2111 to have an interference fit with the second side 1112 of the snap-fit ​​structure 111, and thus enabling the snap-fit ​​structure 211 and the snap-fit ​​structure 111 to rotate and engage. Simultaneously with the snap-fit ​​structure 211 sliding into the second side 1112 of the snap-fit ​​structure 111, the groove 212 on the mating portion 2112 moves accordingly to the position of the protrusion 113 on the cantilever structure 112; during this process, the front side of the mating portion 2112 contacts the protrusion 113 on the rear side of the cantilever structure 112 and applies a compressive force to the cantilever structure 112, causing it to elastically deform, thereby allowing the protrusion 113 to smoothly slide into the groove 212. When the protrusion 113 is fully inserted into the groove 212, the cantilever structure 112 returns to its original shape under its own rebound force, so that the protrusion 113 and the groove 212 are tightly abutted and locked, and finally a stable circumferential limit is formed.

[0040] The technical solution provided by this utility model, through structural improvement, makes the first connecting part 110 of the front mesh cover 100 elastic, allowing it to cooperate with the second connecting part 210 of the aromatherapy cover 200 to achieve a detachable connection. This utility model effectively solves the problem of existing aromatherapy covers 200 being prone to loosening, thus causing resonance and abnormal noise. Specifically, when the first connecting part 110 and the second connecting part 210 are connected to each other, the first connecting part 110 can rely on its own elasticity to tightly connect with the second connecting part 210, improving the installation stability and connection reliability of the aromatherapy cover 200 on the front mesh cover 100, thereby avoiding the resonance and abnormal noise problems caused by the loosening of the aromatherapy cover 200.

[0041] Example 2 This utility model embodiment also provides a fan grille assembly, which includes a front grille 100, a rear grille, an aroma diffuser 300, and an aroma diffuser cover 200, etc. The aroma diffuser 300 is located between the aroma diffuser cover 200 and the front grille 100 and is located inside the aroma diffuser cover 200. The aroma diffuser 300 in this embodiment is the same as the aroma diffuser 300 in Embodiment 1. The aroma diffuser cover 200 in this embodiment has the same structure as the aroma diffuser cover 200 in Embodiment 1, but the aroma diffuser cover 200 in this embodiment is used to snap onto the rear side of the front grille 100. The front grille 100 in this embodiment has a basically the same structure as the front grille 100 in Embodiment 1, the difference being that the position of the protrusion 113 is different.

[0042] Specifically, the front side of the cantilever structure 112 is provided with a protrusion 113 extending forward along the axial direction of the front mesh cover 100. The protrusion 113 is adapted to the groove 212 of the second connecting part 210, so that the aromatherapy cover 200 and the front mesh cover 100 are circumferentially limited by the cooperation of the protrusion 113 and the groove 212.

[0043] The assembly process of attaching the aroma diffuser cover 200 to the rear side of the front mesh cover 100 according to this embodiment of the utility model is as follows: First, place the aroma diffuser cover 200 behind the mounting part 120 of the front mesh cover 100, so that the rear side of the aroma diffuser cover 200 is opposite to the rear side of the mounting part 120 of the front mesh cover 100 (that is, the front side of the aroma diffuser cover 200 and the front side of the front mesh cover 100 face opposite directions, and the rear side of the aroma diffuser cover 200 and the rear side of the front mesh cover 100 face opposite directions), and make their axes substantially parallel, and align the snap-fit ​​structure 211 of the aroma diffuser cover 200 with the first side 1111 of the snap-fit ​​structure 111. Then, pass the snap-fit ​​structure 211 of the aroma diffuser cover 200 forward along its axis through the first side 1111 of the snap-fit ​​structure 111. After the snap-fit ​​structure 211 passes through the first side 1111 of the snap-fit ​​structure 111, the aromatherapy cap 200 is rotated circumferentially to cause the snap-fit ​​structure 211 to slide into the second side 1112 of the snap-fit ​​structure 111, thereby causing the extension portion 2111 to have an interference fit with the second side 1112 of the snap-fit ​​structure 111, and thus enabling the snap-fit ​​structure 211 and the snap-fit ​​structure 111 to rotate and engage. Simultaneously as the snap-fit ​​structure 211 slides into the second side 1112 of the snap-fit ​​structure 111, the groove 212 on the mating portion 2112 moves accordingly to the position of the protrusion 113 on the cantilever structure 112; during this process, the side of the mating portion 2112 contacts the protrusion 113 on the front side of the cantilever structure 112 and applies a compressive force to the cantilever structure 112, causing it to elastically deform, thereby allowing the protrusion 113 to smoothly slide into the groove 212. When the protrusion 113 is fully inserted into the groove 212, the cantilever structure 112 returns to its original shape under its own rebound force, so that the protrusion 113 and the groove 212 are tightly abutted and locked, and finally a stable circumferential limit is formed.

[0044] This utility model embodiment also provides a fan, which includes the fan grille assembly of any of the above-mentioned fan types. Specifically, the fan is a circulating fan.

[0045] It is understandable that, since the fan is equipped with the aforementioned fan grille assembly, it possesses all the technical effects of the aforementioned fan grille assembly, which will not be elaborated upon here.

[0046] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
