Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a fan device. Background Art

[0002] A fan is a device used to generate air flow. It is widely used in many fields such as homes, offices, industrial sites, and electronic equipment cooling. Among the fan products for home use on the market, most of the uprights and foot plates are screw-locking or rotating assembly structures. Users may need tools, such as screwdrivers, when disassembling or assembling, which becomes difficult without proper tools. If the screws are not fully tightened, it may cause structural instability and even produce shaking and noise during use. Wear and looseness: After long-term use, the screws may become loose due to wear, resulting in structural instability. The rotating structure may rely on internal buckles or friction to maintain the connection between components. If the design is not appropriate, it is easy to assemble it in place. Excessive gaps between components or uneven friction will cause abnormal noise when the fan is running. Frequent rotation assembly may cause wear of internal connectors, thereby affecting the life of the product. Therefore, these two structures will cause consumers to disassemble and assemble inconveniently and produce abnormal noises due to inadequate assembly, which will affect the use of the product.

[0025] In the embodiment of the present utility model, Figure 1-8 As shown, the fan device includes a head assembly 1, a support rod 2 and a base 3, and also includes a weight member 4 and a bushing 5. The weight member 4 is installed in the base 3, the outer wall of the bushing 5 is clamped on the weight member 4, and the inner wall of the bushing 5 is clamped on the support rod 2. The head assembly 1 is fixedly connected to the support rod 2.

[0027] In the implementation of this city, a plurality of positioning grooves 42 are opened on the side of the weight member 4 facing the bushing 5, the positioning grooves 42 are connected with the positioning bosses 41, and the positioning bosses 41 are notched toward the positioning grooves 42, and the bushing 5 is also provided with positioning blocks 52 for inserting into the positioning grooves 42.

[0028] In the present implementation, the outer wall of the bushing 5 is recessed inward to form a plurality of recessed portions 53 , and a relief area 54 is extended upward from the bottom of the recessed portion 53 , and the position of the relief area 54 corresponds to the positioning groove 42 .

[0029] In the implementation of this city, the bushing 5 is provided with a positioning column protruding outward on the side facing the support rod 2, and the support rod 2 is recessed inward with a groove 22 matched with the positioning column.

[0030] In the implementation of this city, the base 3 includes an upper cover 31 and a lower cover 32. The upper cover 31 is buckled on the lower cover 32 and matched with each other. The upper cover 31 and the lower cover 32 are connected to form a closed cavity. The weight member 4 is located in the closed cavity. A plurality of fixing holes 43 are opened on the weight member 4. The upper cover 31 is fixedly connected to the lower cover 32 by screws, and the screws are located in the fixing holes 43.

[0031] In the implementation of this city, the head component 1 and the support rod 2 are fixedly connected via a connector 6 , and a glue layer is coated on the bonding surface of the connector 6 and the support rod 2 at one end facing the head component 1 .

[0032] The utility model aims to design a new fan foot plate and vertical rod clamping assembly scheme, which is convenient for disassembly and assembly and not prone to errors in assembly.

[0033] The present application designs a new installation method of the base 3 and the support rod 2. The fan device 3 includes a head assembly 1, a support rod 2 and a base 3, and introduces the design of a weighting member 4 and a bushing 5. The weighting member 4 is located inside the base 3 to increase the overall stability; the bushing 5 serves as an intermediate connecting member, and its outer wall is fixed to the weighting member 4 by clamping, and the inner wall and the support rod 2 are also fixed by clamping with the clamping hook 51 and the clamping hole 21. Such a design not only increases the overall stability of the fan, but also makes it easy to disassemble and assemble, and it is not easy to make mistakes, so that no shaking and noise will be generated during use. There will also be no situation where the gap between the components is too large or the friction is uneven due to improper assembly, which will cause abnormal noise when the fan is running. It not only increases the life of the fan, but also improves the flexibility of use.

[0034] Specifically, in this embodiment, the outer ring of the bushing 5 is designed with three hooks 51, and the weight piece 4 is provided with a positioning boss 41 that matches the hook 51. The bushing 5 is fixed by inserting the three hooks 51 into the three positioning bosses 41 of the weight piece 4; the head assembly 1 is assembled with the support rod 2 through the connecting head 6 and the structural adhesive; the upper cover 31 is designed with five screw columns, and the five screw columns are first passed through the fixing holes on the weight piece 4, and then the attached washers are screwed into the five fixing holes to fix the upper cover 31 and the weight piece 4; the support rod 2 is designed with two hook holes 21 and a groove 22, and the groove 22 is semicircular.

[0035] By designing a plurality of hooks 51 on the inner and outer side walls of the bushing 5, which respectively match the positioning boss 41 on the weight member 4 and the clamping hole 21 on the support rod 2, this design ensures a stable connection and accurate positioning between the support rod 2 and the base 3. A positioning groove 42 is added to the weight member 4 to match the positioning block 52 on the bushing 5, which not only increases the stability of the structure but also simplifies the assembly process. At the same time, the special design of the positioning groove 42 and the positioning boss 41 takes into account the convenience of assembly. The positioning block 52 plays a role in positioning and preventing rotation. The recessed portion 53 and the avoidance area 54 on the outer side wall of the bushing 5 are designed to provide an avoidance space for the bushing 5 to rebound when the support rod 2 is assembled, avoid interference between the hook 51 and other components, and maintain the compactness of the overall structure. By setting the positioning column on the bushing 5 and the corresponding groove 22 on the inner side of the support rod 2, the purpose is to prevent the support rod 2 and the bushing 5 from rotating, thereby ensuring a more accurate docking between the two and improving the stability of the overall structure. The base 3 is composed of an upper cover 31 and a lower cover 32 to form a closed cavity, in which the weighting member 4 is placed and fastened with screws through fixing holes. This design is convenient for weighting and ensures the airtightness and aesthetics of the base 3.

[0036] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
