Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a fan base assembly. Background Technology

[0002] Compared to traditional fans, bladeless fans have their impellers installed inside the base, making them invisible and preventing human contact with the rotating impeller, thus ensuring safety and reliability. A bladeless fan consists of a base and an air outlet ring at the top, with the fan fixed inside the base. The base cylinder has a set of air inlets on its side for external air intake, which affects the product's appearance. Existing fan fixing structures occupy relatively large internal spaces, impacting airflow efficiency. Furthermore, the fan assembly is fixed via a positioning structure at the top of the base cylinder, resulting in relatively poor positioning reliability and, after long-term use, relatively high fan noise, affecting performance.

[0003] For example, patent CN211852220U discloses a fan assembly including an air outlet structure, a base, and a fan assembly for generating airflow; a cylindrical shell is provided below the air outlet structure, and the fan assembly inside is fixed to the top of the base cylindrical shell by fasteners; the positioning reliability is relatively poor, and the fan assembly is relatively noisy after long-term use, affecting the performance.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] The fan assembly is a fan base, which includes a fan chassis, a base cover, a support component, and a built-in fan. The fan chassis has an air inlet for external air to enter. The support component is located on the fan chassis inside the base cover and has a support protrusion. The built-in fan is fixed on the support protrusion. There is a gap between the built-in fan and the support component. The top of the base cover has an opening corresponding to the outlet of the built-in fan.

[0007] Further or preferred:

[0008] The fan chassis has an inverted conical structure, and the air inlet is located on the conical surface to form an inclined air inlet.

[0010] The base cover is equipped with a fan button, and the inner wall of the base cover is equipped with a connecting pillar. The inside of the fan button is connected to the connecting pillar.

[0011] The supporting component is a ring-shaped supporting component. The edge of the ring-shaped supporting component is provided with a docking groove, and the bottom inner wall of the base cover is provided with a connecting lug. The connecting lug is connected to the docking groove.

[0012] The support component has an annular support ring at its edge, and the support ring is provided with through holes for vertical ventilation.

[0013] The support protrusions are a group, and the group of support protrusions are circumferentially spaced on the edge of the annular support component.

[0014] A fan support plate is fixed to the top of the set of support protrusions. The center of the fan support plate is hollow, and the built-in fan is fixed on the fan support plate. The lower inlet of the built-in fan extends out from the hollow structure of the fan support plate.

[0015] The set of support protrusions and annular support components are an integral structure, and the top of the support protrusion is provided with a positioning post for docking with the wind turbine support plate.

[0028] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0029] like Figures 1 to 6 As shown, the fan assembly is a fan base. The top edge of the fan base 1 is provided with a snap-fit ​​structure, which can be connected to different styles of air outlet structures.

[0030] The fan assembly includes a fan chassis 2, a base cover 101, a support component 5, and a built-in fan 4. The fan chassis is provided with an air inlet 201 for external air to enter. The support component is located on the fan chassis inside the base cover. The support component is provided with a support protrusion 503. The built-in fan 4 is fixed on the support protrusion. There is a gap space between the built-in fan and the support component. The top of the base cover is provided with an opening corresponding to the outlet of the built-in fan.

[0031] The fan assembly of this utility model has a reasonable structural design. The inner bottom of the fan base is provided with an annular support component that allows airflow to pass through. The annular support component is provided with a support protrusion. The fan assembly is supported and fixed by the support protrusion, making the structure stable and reliable. It is not easy to loosen after long-term use, and the fan noise changes relatively little in the later stages of use.

[0032] The fan chassis 2 has an inverted conical structure, and the air inlet is located on the conical surface to form an inclined air inlet 201; the support component is rotatably mounted on the fan chassis, and the base cover and the support component are connected by a detachable structure.

[0033] The supporting components are rotatably mounted on the chassis, and the rotating structure adopts an existing conventional structure; the inverted cone-shaped structural design allows for a concealed air intake design.

[0034] The base cover has a fan button 3 and a connecting pillar 103 on the inner wall of the base cover. The inside of the fan button is connected to the connecting pillar. The connecting pillar and the base cover are an integral injection molded structure, which is stable and reliable. The connecting pillar is located at the top inside the base cover, making the fan button easy to install.

[0035] The support component 5 is a ring-shaped support component. The edge of the ring-shaped support component is provided with a docking groove 502. The bottom inner wall of the base cover is provided with a connecting lug 102. The connecting lug is connected to the docking groove. The connecting lug and the base cover are integral injection molded parts. The docking groove is preferably a stepped groove. The connecting lug overlaps in the stepped groove and is then fastened with screws. The structure is stable and reliable.

[0036] Traditional structures involve a series of fixing structures on the base cover to secure various components. However, due to the thin-walled nature of the cover, the structural stability is relatively poor. In contrast, this invention incorporates a built-in breathable support structure, which secures all components and the cover to the support structure. This results in a stable and reliable structure that is less prone to loosening after long-term use and exhibits minimal noise variation.

[0037] The support component has an annular support ring 501 at its edge, and the support ring has through holes 505 for vertical ventilation. The support ring has a convex ring structure to provide structural stability. The through holes are a set of circumferentially arranged through holes, which correspond to the inclined air inlet on the fan chassis, so that the air intake is smooth.

[0038] A fan support plate 6 is fixed to the top of a set of support protrusions 503. The center of the fan support plate is hollow. The built-in fan is fixed on the fan support plate. The lower inlet of the built-in fan extends from the hollow structure of the fan support plate. The airflow is guided to the lower inlet of the built-in fan through a set of circumferentially arranged through holes. The air intake is smooth and the noise is relatively low.

[0039] The support protrusions are a set of circumferentially evenly spaced protrusions, and the set of support protrusions is circumferentially spaced on the edge of the annular support component; the set of support protrusions and the annular support component are an integral structure, and the top of the support protrusion is provided with a positioning post 504 for docking with the fan support plate, and the structure is stable and reliable.

[0040] A fan housing 7 is fixed on the fan support plate, and the built-in fan is located inside the fan housing. A set of support protrusions consists of three support protrusions; the support protrusions have a certain height, and there is a certain gap space between the lower inlet of the built-in fan assembly and the support component, so that the air intake is smooth.
