Technical Field

[0001] This utility model relates to the field of fan electrical appliances, and in particular to a fan with a simple anti-tipping counterweight. Background Technology

[0002] In existing fan designs, especially for outdoor fans, users often need to adjust the fan height according to the actual usage environment to meet different needs.

[0003] In existing fan designs, the fan height can be adjusted by adding or removing connecting support rods; additionally, the base typically serves as a counterweight to ensure fan stability. However, in fans with basic storage functionality, the height-adjusting support rods need to be stored in the base when not in use, making the base no longer a counterweight. Therefore, traditional fan counterweight structures are no longer suitable for retractable fans, necessitating the development of new fan counterweight structures to ensure fan stability in both height-adjustable and retracted states, while simultaneously meeting users' needs for height adjustment and portability.

[0027] Reference Figures 1 to 5 In some embodiments, this utility model discloses a fan with a simple anti-tipping counterweight, which includes:

[0028] Reference Figure 1 Combination Figure 2The fan body 100 shown includes a fan head 110 and a mounting base 120 hinged to the fan head 110. The fan head 110 can swing at a certain tilt angle relative to the mounting base 120 to adapt to different usage environments. This structure allows the fan to provide airflow at different angles, increasing the flexibility and comfort of use.

[0029] Continue to refer to Figure 1 Combination Figure 2 As shown, multiple support rods 200 are detachably connected to the fan body 100, with a base 300 detachably connected to the end of one of the support rods 200 at the bottom. Preferably, the mounting base 120 is threadedly connected to the top section of the support rod 200, and the multiple support rods 200 are connected by threads. The threaded connection provides a stable and adjustable connection, allowing users to easily adjust the fan height as needed, improving ease of use and stability. The cavity is used to house one or more of the support rods 200 in the fan height adjustment state. The fan height is adjusted by connecting or removing the support rods 200, and the one or more support rods 200 in the detached state are housed in the cavity of the base 300. This structure allows users to flexibly adjust the fan height as needed, and when not in use, the support rods can be detached and stored in the cavity of the base, reducing space occupation and facilitating carrying and storage, making it particularly suitable for outdoor use.

[0030] Reference Figure 1 As shown, a counterweight 400 is provided at the bottom of the support rod 200 at its lower end. The counterweight 400 is located near the base 300, which has an internal cavity. The counterweight provides additional weight when the support rod 200 is connected, enhancing the stability of the fan, preventing it from tipping over during use, and improving safety. Furthermore, the counterweight at the bottom of the support rod, instead of the base, serves as the main body of the counterweight, allowing the base to accommodate other fan components and increasing the convenience of outdoor use.

[0031] Reference Figure 1 Combination Figure 3 , 5 As shown, the base 300 is provided with a first mounting port 310 for detachable connection with the bottom end of the support rod 200. The outer ring of the first mounting port 310 is provided with a first reinforcing rib structure 311 integrally connected to the bottom wall of the base 300. The first reinforcing rib structure on the base improves the load-bearing capacity and durability of the base 300. Especially when the support rod 200 is under great force, it can effectively prevent the deformation and damage of the base 300, ensuring the stability and reliability of the fan.

[0032] Continue to refer to Figure 1Combination Figure 3 , 5 As shown, a cover 500 is correspondingly provided above the base 300. The cover 500 has a second mounting opening 510 for engaging with the support rod 200. The second mounting opening 510 corresponds to the first mounting opening 310. The outer ring of the second mounting opening 510 is provided with a second reinforcing rib structure 511 integrally connected to the top wall of the cover 500. The design of the cover 500 effectively prevents dust and moisture from entering the cavity of the base 300, protecting the internal components from environmental factors. At the same time, the second reinforcing rib structure further improves the load-bearing capacity and durability of the cover 500 when it is fitted with the support rod.

[0033] Continue to refer to Figure 1 As shown, the bottom end of the support rod 200 is threadedly connected to the first mounting port 310. A gap 210 is provided between the bottom end of the support rod 200 and the bottom wall of the fan body 100. This gap is left so that the center of the counterweight at the bottom of the support rod is offset from the bottom of the base, making the center of gravity of the entire fan slightly off the base, thus increasing the stability of the fan during use. In some embodiments, the height of the gap 210 is not less than one-third of the height of the threaded connection between the support rod 200 and the first mounting port 310. This height of the gap 210 makes the center of gravity of the fan's counterweight most stable.

[0034] Continue to refer to Figure 1 As shown, the base 300 is connected to the outer edge of the cover 500 via a snap-fit ​​component 900. The support rod 200 has a circumferentially protruding portion 220. Near the second mounting opening 510, the top and bottom ends of the cover 500 are pressed down by the protruding portion 220 and the top end of the first mounting opening 310, respectively. This snap-fit ​​connection makes the connection between the base 300 and the cover 500 more secure and stable. The protruding portion 220, together with the top end of the base 300, presses down on the cover, restricting the movement of the support rod 200 and further ensuring the overall stability of the fan.

[0035] Reference Figure 1 As shown, the base 300 is provided with a groove 320 for easy gripping by the user. One end of the shell portion of the groove 320 is integrally connected to the outer wall of the first reinforcing rib structure 311 and the first mounting port 310.

[0036] Reference Figure 1 As shown, a limiting portion 230 is provided at the threaded connection of adjacent support rods 200. The limiting portion 230 ensures the accuracy and consistency of the support rods 200 when connecting and adjusting their height, avoids connection instability caused by excessive rotation, and improves the reliability and service life of the product.

[0037] In some embodiments, the counterweight 400 is made of one or more of metal, inorganic mineral materials, or concrete. These materials have high density and weight, which can effectively increase the weight of the support rod 200 and improve the stability of the fan. At the same time, these materials also have good durability and corrosion resistance, can adapt to various usage environments, and extend the service life of the product.

[0038] The above description is merely a preferred embodiment of this utility model. This utility model is not limited to the above-described embodiments. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this disclosure, as long as they achieve the same technical effect, should be included within the scope of protection of this disclosure and fall under the protection scope of this utility model. Within the protection scope of this utility model, the technical solutions and / or implementation methods can have various modifications and variations.
