[0027] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other. Those skilled in the art will understand that a fan assembly of this application is applicable to various household appliances, especially heaters or fans.

[0028] As shown in Figure 1 and 7 , the application provides a fan assembly, which comprises a fan support 1 and a fan 6; the fan 6 is arranged on the fan support 1 and connected with the fan support 1 into an integrated structure. Specifically, the fan support 1 is provided with a clamping structure and an elastic element 4; the fan 6 is abutted on the elastic element 4 and clamped together with the clamping structure, thereby being installed on the fan support 1. The fan assembly provided by the application is elastically installed through the clamping structure and the elastic element 4 on the fan support 1 and matched with the fan 6 respectively; wherein the fan 6 deforms the elastic element 4 by extrusion, so that the clamping structure can be clamped on the fan 6 to realize clamping installation. The fan assembly provided by the application is more stable when the fan is fixed because the elastic element itself has elasticity; the clamping structure and the elastic element are elastically matched, so that the fixing tolerance of the fan is larger, which can save material and labor costs and reduce the use of assembly screws.

[0029] As shown in Figures 1-3 , Figure 7 , in some embodiments, the fan support 1 is provided with a fan mounting surface 2, and the fan 6 is arranged on the fan mounting surface 2. Specifically, the fan mounting surface 2 is provided with a groove 21; the elastic element 4 is arranged in the groove 21 and protrudes from the fan mounting surface 2, so that the fan 6 can extrude and deform the elastic element 4 when installed on the fan mounting surface 2, thereby cooperating with the clamping structure for clamping. As shown in Figures 2 to 4 , the elastic element 4 is integrally formed with the fan support 1, one end of the elastic element 4 is arranged in the groove 21, and the other end of the elastic element 4 is a free end, so that the elastic element 4 can be elastically extruded and deformed, meeting the extrusion assembly requirements.

[0030] As shown in Figures 2-4 , in some embodiments, one end of the elastic element 4 is arranged on the side wall of the groove 21, and the elastic element 4 is provided with a protruding point 41, the height H of the protruding point 41 protruding from the fan mounting surface 2 is 0.1-5mm, preferably 1mm, 2mm or 3mm, so as to abut on the bottom surface of the fan. In the above scheme, the protruding point 41 of the elastic element 4 is designed to protrude from the fan mounting surface 2 by a predetermined height, so that the fan is more stable during extrusion and deformation, and can effectively cooperate with the clamping structure to clamp the fan, realizing stable installation.

[0031] As shown in Figures 5-6 , in some embodiments, the elastic element 4 is a long strip structure, one end surface of which protrudes to form a protruding point 41; the length of the elastic element 4 is 1-10mm, the width is 1-10mm, and the thickness is 1-10mm. Preferably, the fan support 1 and the elastic element 4 can be plastic parts.

[0032] AsFigure 1 , 7 As shown in Figure 9, in some embodiments, the snap-fit ​​structure is preferably a snap-fit ​​3. The snap-fit ​​3 is disposed on the fan mounting surface 2, preferably on one side of the fan mounting surface 2, so as not to interfere with the installation of the fan and to clamp the fan from the side. The snap-fit ​​3 is perpendicular to the fan mounting surface 2 and forms an inverted structure at its end. The bottom of this inverted structure forms a snap-fit ​​surface 31, which allows it to snap onto the fan 6 for assembly. An elastic element 4 can be disposed on one side of the snap-fit ​​3, thus fully utilizing the elastic force of the elastic element 4's deformation to cooperate with the snap-fit ​​structure to clamp the fan 6. That is, the snap-fit ​​3 and the elastic element 4 cooperate with each other to clamp the fan 6 onto the fan mounting surface 2.

[0033] like Figure 9 As shown, in some embodiments, the buckle 3 is provided with a snap-fit ​​surface 31, which is used to clamp the fan. The fan 6 is provided with a connecting surface 61, which is used to cooperate with the snap-fit ​​surface 31 to achieve fan installation and clamping. Specifically, the buckle 3 is clamped together with the connecting surface 61 of the fan 6 through the snap-fit ​​surface 31, thereby fixing the fan 6 to the fan mounting surface 2 of the fan bracket 1.

[0034] like Figure 9 As shown, in some embodiments, the connecting surface 61 and the bottom surface of the fan 6 are respectively clamped between the snap-fit ​​surface 31 and the fan mounting surface 2. Furthermore, the fan 6 is moderately lifted on the fan mounting surface 2 by an elastic element 4, thereby forming a clamping structure with the snap-fit ​​surface 31. To ensure that the snap-fit ​​surface 31 can be fully clamped onto the connecting surface 61 of the fan, the vertical distance between the snap-fit ​​surface 31 and the fan mounting surface 2 is 0.1 to 3 mm greater than the vertical distance between the connecting surface 61 and the bottom surface of the fan 6, preferably 1 mm, 1.5 mm, or 2 mm. Then, the fan is snapped and secured by the height of the lifting of the elastic element 4. This structural design ensures the combined effect of the snap-fit ​​and the elastic element, thus firmly fixing the fan to the fan mounting surface, achieving flexible assembly, and facilitating disassembly and assembly.

[0035] like Figure 1 As shown, in some embodiments, the fan mounting surface 2 is further provided with a baffle in the circumferential direction, and the fan is installed in the baffle. The fan mounting surface 2 can be designed as a quadrilateral structure, with the snap-fit ​​structure set at one corner of the fan mounting surface 2, and a baffle provided at the other corner of the fan mounting surface 2. This allows the fan to be clamped from the diagonal direction, resulting in more reasonable force distribution and a more compact installation.

[0036] like Figure 1 As shown, in some embodiments, the fan mounting surface 2 can be designed as a quadrilateral structure, with multiple elastic elements 4 symmetrically distributed on the fan mounting surface 2. This allows the fan to be evenly supported from the bottom surface, resulting in more uniform force distribution and more reliable installation.

[0037] like Figure 1 As shown, in some embodiments, the fan support 1 is also provided with multiple guide vanes 5. Specifically, the fan support 1 has a duct structure inside the duct, which includes multiple guide vanes 5. The multiple guide vanes 5 are evenly fixed inside the duct to guide the airflow and effectively increase the wind speed.

[0038] This application also provides a heater, including a fan assembly; the fan assembly is the fan assembly described above.

[0039] The fan assembly and heater proposed in this application have the following technical advantages:

[0040] (1) The fan assembly proposed in this application, through the design of a snap-fit ​​structure and elastic components, makes the fan installation more convenient, easier to disassemble and assemble, and easier to process and shape.

[0041] (2) The fan assembly proposed in this application, through the design of a snap-fit ​​structure and the cooperation of elastic components, makes the installation of the fan simpler and more reliable, and can effectively reduce costs.

[0042] Although the embodiments disclosed in this application are as described above, the content is merely for the purpose of facilitating understanding of this application and is not intended to limit this application. Any person skilled in the art to which this application pertains may make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed in this application; however, the scope of patent protection of this application shall still be determined by the scope defined in the appended claims.
