In order to meet the requirements of miniaturization and thinness, the existing air exchange device, such as a bathroom heater, usually has a very thin panel. However, the thin panel is prone to deformation such as bending and twisting, resulting in uneven surface of the panel.

[0003] Therefore, the panel structure of the existing air exchange device still needs to be improved. SUMMARY

[0006] In some optional embodiments, the first limiting component comprises a connecting part and a limiting part connected thereto, the connecting part is connected with the panel, and a first gap exists between the limiting part and the panel; at least part of the structure of the clamping component is accommodated in the first gap, the movement of the clamping component in the thickness direction of the panel can be limited by the limiting part, so that the panel can be connected with the clamping component in a clamping manner by the limiting part, so as to support the panel by the clamping component. The size of the first gap in the thickness direction of the panel is greater than or equal to the size of the at least part of the clamping component in the thickness direction, which can facilitate the placement of the clamping part of the clamping component in the first gap.

[0007] In some alternative embodiments, the clamping assembly comprises a first extension plate and a second extension plate, the first extension plate is perpendicular to the second extension plate, the first extension plate extends towards the first gap and is inserted into the first gap.

By arranging at least part of the structure of the second extension plate to be accommodated in the second gap, the second part of the second limiting assembly can limit the movement of the second extension plate in the thickness direction of the panel, so that the first limiting assembly and the third limiting assembly can limit the movement of the clamping assembly in the thickness direction of the panel on the first side and the second side of the clamping assembly respectively, and the cooperation between the clamping assembly and the panel can be more closely, thereby more effectively preventing the panel from deforming.

[0009] In some alternative embodiments, the second extension plate has a clamping groove on the side of the second extension plate away from the panel, and at least part of the structure of the second part of the second limiting assembly is accommodated in the clamping groove.

[0013] In some optional embodiments, the first limiting component is a plurality of, and the plurality of first limiting components are distributed at intervals on one side of the clamping assembly.

[0027] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0028] In the description of the present application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0029] As mentioned before, in order to meet the needs of miniaturization and thinness, the existing ventilation equipment usually designs the panel to be very thin. However, the very thin thickness of the panel makes the panel prone to deformation such as bending and twisting, causing the panel surface to be uneven.

[0030] In this embodiment, the panel structure includes a panel, at least one first limiting component, and at least one engaging component. The first limiting component is disposed on the surface of the panel, and the panel is engaged with the engaging component through the first limiting component. Based on the engaging connection between the panel and the engaging component, the engaging component can be fixed to the panel, preventing relative movement between the engaging component and the panel. Thus, when the panel is about to undergo bending or torsion deformation, the engaging component and the panel can share the force, using the engaging component to support the panel and prevent bending or torsion deformation, thereby keeping the panel as flat as possible.

[0031] It should be noted that the accompanying drawings in this application are only for the purpose of illustrative purposes and understanding of this embodiment, and are not intended to limit this application in any way. They are not necessarily drawn to scale. The X, Y, and Z axes in each drawing are used to indicate the direction of extension of the corresponding axis.

[0032] According to a first aspect of the embodiments of this application, a panel structure for a ventilation device is provided. The ventilation device can be a ventilation fan, a bathroom heater, or a bathroom heater, etc. The panel structure will be described in detail below with reference to the accompanying drawings.

[0033] like Figures 1-4 As shown, the panel structure 100 for a ventilation device provided in this application embodiment includes a panel 110, at least one first limiting component 120, and at least one engaging component 130. The first limiting component 120 is disposed on the surface of the panel 110, and the panel 110 is engaged with the engaging component 130 through the first limiting component 120.

[0034] The panel 110 of the panel structure 100 can be connected to the housing of the ventilation device, and the panel 110 and the housing form the internal space of the ventilation device. The panel 110 may include a first surface and a second surface, wherein the first surface is located within the internal space and the second surface is located outside the internal space. The first limiting component 120 is preferably disposed on the first surface, but of course, the first limiting component 120 may also be disposed on the second surface, and this application does not limit this.

[0035] The panel 110 has a small dimension in its thickness direction Z. The engaging component 130 can be used to provide support for the panel 110 in the thickness direction Z to prevent the panel 110 from deforming due to its small thickness dimension.

[0036] like Figure 1 or Figure 3As shown, in some optional embodiments, the panel structure 100 may include two engaging components. The panel 110 may be rectangular in shape, and the positions of the two engaging components 130 may be symmetrical about an axis of symmetry of the panel 110 parallel to the second direction Y, thereby making the support of the panel 110 by the engaging components 130 more uniform. Of course, the panel structure 100 may include one, three, or four engaging components 130. Similarly, when the number of engaging components 130 is four, the positions of two of the four engaging components 130 may be symmetrical about an axis of symmetry of the panel 110 parallel to the first direction X, and the positions of the other two engaging components 130 may be symmetrical about an axis of symmetry of the panel 110 parallel to the second direction Y, thereby strengthening the support of the engaging components 130 on the panel. It should be understood that in an embodiment with two engaging components 130, removing one engaging component 130 can result in an embodiment with one engaging component 130. In an embodiment where the number of engaging components 130 is four, removing one engaging component 130 results in an embodiment where the number of engaging components 130 is three.

[0037] In this embodiment, the panel structure 100 includes a panel 110, at least one first limiting component 120, and at least one engaging component 130. The first limiting component 120 is disposed on the surface of the panel 110, and the panel 110 is engaged with the engaging component 130 through the first limiting component 120. Based on the engaging connection between the panel 110 and the engaging component 130, the engaging component 130 can be fixed on the panel 110, preventing relative movement between the engaging component 130 and the panel 110. Thus, when the panel 110 is about to undergo bending or torsion deformation, the engaging component 130 and the panel 110 can share the force, using the engaging component 130 to support the panel 110, preventing bending or torsion deformation, thereby allowing the panel 110 to remain as flat as possible.

[0038] like Figure 2 As shown, in some optional embodiments, the first limiting component 120 includes a connecting portion 121 and a limiting portion 122 connected to the connecting portion 121. The connecting portion 121 is connected to the panel 110, and a first gap exists between the limiting portion 122 and the panel 110. At least a portion of the structure of the engaging component 130 is accommodated within the first gap. Furthermore, the dimension of the first gap in the thickness direction Z of the panel 110 is greater than or equal to the dimension of at least a portion of the engaging component 130 in the thickness direction Z.

[0039] Specifically, the dimension of the first gap in the thickness direction Z of the panel 110 can be greater than or equal to the dimension of the engaging portion on the engaging assembly 130 in the thickness direction Z of the panel 110. The engaging portion on the engaging assembly 130 is the portion of the engaging assembly 130 that is accommodated in the first gap, so as to place the engaging portion on the engaging assembly 130 in the first gap.

[0040] In this embodiment, the first limiting component 120 includes a connecting portion 121 and a limiting portion 122 connected thereto. The connecting portion 121 is connected to the panel 110, and there is a first gap between the limiting portion 122 and the panel 110. At least a portion of the structure of the engaging component 130 is accommodated within the first gap. The limiting portion 122 can be used to restrict the movement of the engaging component 130 along the panel thickness direction Z, so that the panel 110 can be connected to the engaging component 130 by the limiting portion 122, so that the panel 110 can be supported by the engaging component 130.

[0041] like Figures 2-4 As shown, in some optional embodiments, the engaging assembly 130 may include a first extension plate 131 and a second extension plate 132, the first extension plate 131 being perpendicular to the second extension plate 132. The first extension plate 131 extends toward the first gap and is inserted into the first gap.

[0042] The thickness direction of the first extension plate 131 can be parallel to the thickness direction Z of the panel 110, and the thickness direction of the second extension plate 132 can be perpendicular to the thickness direction Z of the panel 110. As a feasible embodiment, the first extension plate 131 and the second extension plate 132 can be strip-shaped plates, with the width direction of the first extension plate 131 being a first direction X and the length direction being a second direction Y. Of course, the first extension plate 131 and the second extension plate 132 can also be other shapes, such as trapezoids, triangles, etc., and this application does not impose any limitations on this.

[0043] The dimension of the second extension plate 132 in the thickness direction Z of the panel 110 can be larger than that of the first extension plate 131 in the thickness direction Z of the panel 110, so that the second extension plate 132 has greater rigidity in the thickness direction Z of the panel 110, making the engaging assembly 130 less prone to deformation in the thickness direction Z of the panel 110. For example, the side of the second extension plate 132 near the panel 110 can be coplanar with the side of the first extension plate 131 near the panel 110, and the side of the second extension plate 132 away from the panel 110 protrudes in a direction away from the panel 110 relative to the side of the first extension plate 131 away from the panel 110.

[0044] In this embodiment, the engaging assembly 130 includes a first extension plate 131 and a second extension plate 132. The first extension plate 131 is perpendicular to the second extension plate 132. The first extension plate 131 extends toward the first gap and is inserted into the first gap. The engaging assembly 130 can form an engaging connection with the panel 110 through the first extension plate 131 and the first limiting assembly 120. Furthermore, the second extension plate 132 can be used as a reinforcing rib to enhance the rigidity of the engaging assembly 130, thereby improving the ability of the engaging assembly 130 to resist deformation.

[0045] like Figures 1-4 As shown, in some optional embodiments, the panel structure 100 further includes a second limiting component 140; along the first direction X, the first limiting component 120 is located on the first side of the engaging component 130, and the second limiting component 140 is located on the second side of the engaging component 130, and the first direction X is perpendicular to the thickness direction Z of the panel 110.

[0046] The second limiting component 140 includes a first part and a second part. The first part of the second limiting component 140 is connected to the panel 110, and the second part is located on the side of the first part away from the panel 110, and can be connected to the first part. A second gap exists between the second part and the panel 110, and at least a portion of the structure of the second extension plate 132 is accommodated within the second gap, allowing the panel 110 to form a snap-fit ​​connection with the second extension plate 132 through the second part of the second limiting component 140. The second limiting component 140 can be a detachable limiting member such as a bolt or screw. Taking a bolt as an example, the first part of the second limiting component 140 is the bolt shank, and the second part of the second limiting component 140 is the bolt nut.

[0047] The dimension of the second gap in the thickness direction Z of the panel 110 can be greater than or equal to the dimension of the engaging portion on the second extension plate 132 in the thickness direction Z of the panel 110. The engaging portion on the second extension plate 132 is the part of the second extension plate 132 that is accommodated in the second gap.

[0048] In this embodiment, by setting at least a portion of the structure of the second extension plate 132 to be accommodated within the second gap, the second portion of the second limiting component 140 can restrict the movement of the second extension plate 132 in the thickness direction Z of the panel 110. This allows the first limiting component 120 and the third limiting component 150 to be positioned on the first and second sides of the engaging component 130, respectively, thus restricting the movement of the engaging component 130 in the thickness direction Z of the panel 110. This makes the engagement of the engaging component 130 with the panel 110 more tightly fitted, thereby more effectively preventing the panel 110 from deforming.

[0049] like Figure 2 or Figure 4As shown, in some alternative embodiments, the second extension plate 132 has a locking groove 133 located on the side of the second extension plate 132 away from the panel 110, and at least a portion of the structure of the second portion of the second limiting component 140 is accommodated in the locking groove 133.

[0050] By providing a locking groove 133 on the side of the second extension plate 132 away from the panel 110, and by accommodating at least a portion of the structure of the second part of the second limiting component 140 within the locking groove 133, the second limiting component 140 can restrict the movement of the sidewall of the locking groove 133 along the second direction Y, thereby restricting the movement of the locking component 130 along the second direction Y. This more comprehensively prevents the locking component 130 from moving relative to the panel 110, so that the locking component 130 can provide support for the panel 110.

[0051] like Figure 3 or Figure 4 As shown, in some optional embodiments, the panel structure 100 further includes a third limiting component 150, which is disposed on the same surface of the panel 110 as the first limiting component 120. Along the first direction X, the first limiting component 120 is located on a first side of the engaging component 130, and the third limiting component 150 is located on a second side of the engaging component 130. The third limiting component 150 may be located on the same side of the engaging component 130 as the second limiting component. The first direction X is perpendicular to the thickness direction Z of the panel 110.

[0052] The distance between the connecting portion 121 of the third limiting component 150 and the first limiting component 120 in the first direction X can be greater than or equal to the dimension of the engaging component 130 in the first direction X, so that the engaging component 130 can be installed between the connecting portion 121 of the third limiting component 150 and the first limiting component 120. Furthermore, the third limiting component 150 can be connected to the second limiting component 140, thereby restricting the movement of the engaging component 130 together with the second limiting component 140.

[0053] In this embodiment, the panel structure 100 further includes a third limiting component 150, which is disposed on the same surface of the panel 110 as the first limiting component 120. Along the first direction X, the first limiting component 120 is located on the first side of the engaging component 130, and the third limiting component 150 is located on the second side of the engaging component 130. Thus, the third limiting component 150 and the first limiting component 120 can respectively restrict the movement of the engaging component 130 on the first and second sides of the engaging component 130 in the first direction X, further preventing the engaging component 130 from moving relative to the panel 110, thereby facilitating the engaging component 130 to provide support for the panel 110.

[0054] like Figures 1-4As shown, in some optional embodiments, at least one clearance notch 134 is provided on the first extension plate 131, the clearance notch 134 being located on the side of the first extension plate 131 near the first limiting component 120. The dimension of the clearance notch 134 in the second direction Y is larger than the dimension of the first limiting component 120 in the second direction Y. The first direction X, the second direction Y, and the thickness direction Z of the panel 110 are perpendicular to each other.

[0055] The panel 110 may be provided with a third limiting component 150 and a second limiting component 140. However, the third limiting component 150 and the second limiting component 140 may obstruct the installation of the engaging component 130. By providing the above-mentioned clearance notch 134, the first limiting component 120 can be partially located in the clearance notch 134, which can reduce the space restriction for installing the engaging component 130, thereby making the installation of the engaging component 130 more convenient.

[0056] As in the above embodiment, the first limiting component 120 may include a connecting portion 121 and a limiting portion 122. The dimension of the clearance notch 134 in the second direction Y may be larger than the dimension of the limiting portion 122 in the second direction Y. This embodiment does not limit the size relationship between the dimensions of the clearance notch 134 and the connecting portion 121 in the second direction Y.

[0057] The orthographic projection of the clearance notch 134 on the panel 110 and the orthographic projection of the first limiting component 120 on the panel 110 can be separate or partially intersecting, thereby preventing the first limiting component 120 from passing through the clearance notch 134 and separating the snap-fit ​​connection between the panel 110 and the snap-fit ​​component 130. When the first limiting component 120 may include a connecting portion 121 and a limiting portion 122, the orthographic projection of the clearance notch 134 on the panel 110 and the orthographic projection of the limiting portion 122 on the panel 110 can be separate or partially intersecting.

[0058] In this embodiment of the application, at least one clearance notch 134 is provided on the first extension plate 131. The clearance notch 134 is located on the side of the first extension plate 131 near the first limiting component 120. The size of the clearance notch 134 in the second direction Y is larger than the size of the first limiting component 120 in the second direction Y, so that at least a part of the first limiting component 120 can pass through the clearance notch 134, thereby facilitating the installation of the engaging component 130 between the first limiting component 120 and the third limiting component 150.

[0059] As a feasible implementation, the size of the clearance notch 134 in the first direction X can be larger than the size of the first limiting component 120 in the first direction X, so that the first limiting component 120 can pass through the clearance notch 134 more easily, further facilitating the installation of the engaging component 130.

[0060] likeFigures 1-4 As shown, in some optional embodiments, the panel structure 100 further includes a fourth limiting component 160; along the second direction Y, the fourth limiting component 160 is located on one side of the engaging component 130, and the engaging component 130, the third limiting component 150, and the first limiting component 120 are located on the same side of the fourth limiting component 160. The first direction X, the second direction Y, and the thickness direction Z of the panel 110 are perpendicular to each other. The fourth limiting component 160 can limit the engaging component 130 in the second direction Y, which helps to prevent the engaging component 130 from moving relative to the panel 110 and facilitates the engaging component 130 in providing support for the panel 110.

[0061] As a possible implementation, the fourth limiting component 160 contacts the engaging component 130, and in this case, the orthographic projection of the clearance notch 134 on the panel 110 and the orthographic projection of the first limiting component 120 on the panel 110 can be separated or partially intersected, and / or, at least a portion of the structure of the second part of the second limiting component 140 can be accommodated in the engaging groove 133. Therefore, during the installation of the locking assembly 130, it is only necessary to place the locking assembly 130 at the position where it contacts the fourth limiting assembly 160. This allows the orthographic projection of the clearance notch 134 on the panel 110 and the orthographic projection of the first limiting assembly 120 on the panel 110 to be separated or partially intersected. And / or, when further installing the second limiting assembly 140, at least a portion of the second part of the second limiting assembly 140 can be directly installed in the locking groove 133 without adjusting the relative positions of the clearance notch 134 and the first limiting assembly 120, and / or adjusting the relative positions of the second limiting assembly 140 and the locking groove 133. This can effectively improve the installation efficiency of the locking assembly 130.

[0062] like Figure 1 or Figure 3 As shown, in some optional embodiments, there are multiple first limiting components 120, and these multiple first limiting components 120 are spaced apart on one side of the engaging component 130. As a feasible implementation, the first limiting components 120 can be spaced apart along the second direction Y.

[0063] Similar to the first limiting component 120, there may be multiple second limiting components 140 and third limiting components 150, and the multiple second limiting components 140 and multiple third limiting components 150 may also be distributed at intervals along the second direction Y.

[0064] Optionally, the first limiting component 120 and the second limiting component can also be a single entity. When the first limiting component 120 is a single entity, the first limiting component 120 can have a larger size in the second direction Y. For example, the size of the first limiting component 120 in the second direction Y can be greater than or equal to half the size of the engaging component 130 in the second direction Y. Similarly, when the third limiting component 150 is a single entity, the third limiting component 150 can also have a larger size in the second direction Y. For example, the size of the third limiting component 150 in the second direction Y can be greater than or equal to half the size of the engaging component 130 in the second direction Y.

[0065] In this embodiment of the application, by setting multiple first limiting components 120 and distributing the multiple first limiting components 120 at intervals on one side of the engaging component 130, the multiple first limiting components 120 can limit the engaging component 130 at multiple positions in the second direction Y, and the engaging component 130 can support the panel 110 at multiple positions in the second direction Y, which is beneficial for the engaging component 130 to prevent the panel 110 from deforming.

[0066] like Figure 1 or Figure 3 As shown, as a feasible implementation, corresponding to the first limiting component 120, the locking component 130 can also have multiple clearance notches 134, and each clearance notch 134 corresponds one-to-one with the first limiting component 120. In this embodiment, when installing the locking component 130, at least a portion of each first limiting component 120 can pass through its corresponding clearance notch 134, making it easy to install the locking component 130 and improving the installation efficiency of the locking component 130.

[0067] In some optional embodiments, the locking assembly is made of stainless steel. This not only makes the locking assembly less prone to corrosion in humid environments such as bathrooms, but also utilizes the high rigidity of stainless steel to provide sufficient support for the panel 110. Furthermore, compared to materials such as copper and aluminum, stainless steel has the advantage of low cost, thus reducing manufacturing costs. In other optional embodiments, the locking assembly can also be made of other metals or non-metals with high rigidity, as long as the locking assembly is not easily deformed.

[0068] According to a second aspect of the embodiments of this application, a ventilation device is provided, which includes the panel structure 100 described in any of the foregoing embodiments. The ventilation device provided in this application is based on the same inventive concept as the aforementioned panel structure 100 embodiments and can achieve the same effect. For the specific implementation process, please refer to the description in the aforementioned panel structure 100 embodiments, which will not be repeated here.
