[0033] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0034] Please refer to Figure 1 , Figure 6 The utility model provides a technical scheme:

[0035] An optimized multi-angle adjusting floor fan, comprising: a fan head; a base provided with a connecting piece installation cavity; a connecting piece adapted to be installed in the connecting piece installation cavity and achieving multi-angle activity adjustment of the fan head in the pitch direction through a rotating shaft; the top of the connecting piece is provided with a clamping block for cooperating with the bayonet of the fan head for installation

[0036] Embodiment 1: overall structure and installation

[0037] As Figure 1 and Figure 2 shown, the device comprises a fan head (1), a base (2) and a connecting piece (3). The top of the base (2) is provided with a connecting piece installation cavity (21), and the connecting piece (3) is embeddedly installed in the connecting piece installation cavity (21) and linked with the support body (31) through a rotating shaft (32), so as to achieve multi-angle adjustment of the fan head (1).

[0038] Fan head (1) includes fan cover (11), fan blade and tail tooth box shell (12), tail tooth box shell (12) is fixed by the cooperation of bayonet (121) and the clamping block (36) of connecting piece (3). Tail tooth box shell (12) is internally provided with driving motor (14) for driving fan blade rotation to generate air flow.

[0039] Example 2: pitch adjustment function and limit protection

[0040] As shown in Figure 3 and Figure 4 Connecting piece (3) includes support body (31) and rotating shaft (32). Rotating shaft (32) is installed through rotating shaft camber (33) and rotating shaft installation cavity (27), and support body (31) is movable along the pitch direction with rotating shaft (32) as the core.

[0041] In order to prevent the adjustment angle from exceeding the limit, limit wall (28) is arranged in connecting piece installation cavity (21). When fan head (1) is adjusted upward along the pitch direction to 90°, limit support block (38) contacts with limit wall (28), which provides limit protection and avoids excessive pressure on connecting piece (3) and rotating shaft (32).

[0042] Example 3: design of positioning structure

[0043] As shown in Figure 5 Connecting piece (3) is equipped with positioning structure (4), including positioning concave cavity (26) and elastic positioning protrusion (37). Positioning concave cavity (26) is distributed along the inner wall of connecting piece installation cavity (21), and elastic positioning protrusion (37) is installed in support body (31). When fan head (1) is adjusted to the target angle, protrusion (37) is elastically inserted into the corresponding concave cavity (26), which realizes stable positioning of fan head (1) and avoids angle deviation caused by vibration or inertia.

[0044] Example 4: optimization design of air guide

[0045] As shown in Figure 6 Fan cover (11) is provided with air outlet (111), and air guide slope (112) is arranged at the inner edge of air outlet (111), which is horn-shaped outwardly expanded in cross section.

[0046] Air guide slope (112) reduces the separation phenomenon of air flow in the cover, and significantly reduces airflow friction;

[0047] Horn-shaped air outlet (111) increases the air supply area, reduces the running noise and improves the user experience.
