[0041] The present invention provides a top-blowing energy-saving fan with a waterproof structure. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples.

[0042] In the description of the present invention, it should be understood that the terms "up, down, left, right, etc." indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and should not be understood as limiting the present invention; in addition, the terms "installation" and "connection" should be understood in a broad sense, and those skilled in the art can understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0043] See also Figures 1 to 6 The present invention provides a top-blowing energy-saving fan with a waterproof structure, comprising a fan bracket 1, an arc-shaped fan blade 2, a fan blade embedding groove 3, a rotating shaft 4, a waterproof cover 5, a rain cover 6, a drainage groove 7 and two fixed circular plates 8 set opposite to each other, the fan blade embedding groove 3 is cleverly opened on the reinforced circular plate, the arc-shaped fan blade 2 is cleverly inserted through these slots, and is mounted on the inner side of the two reinforced circular plates, the ends of the arc-shaped fan blade 2 extend from the fan blade embedding groove 3 to the outer side wall of the fixed circular plate 8 respectively, the rotating shaft 4 is fixed at the center of the outer side wall of the fixed circular plate 8, and a plurality of the drainage grooves 7 are radially arranged on the outer side wall of the fixed circular plate 8; it can be understood that the number of the drainage grooves 7 can be multiple, and the multiple drainage grooves 7 are radially distributed on the outer side wall of the fixed circular plate 8. In this embodiment, the number of the drainage grooves 7 is four. In more detail, the end of each drainage groove 7 points to the end of the arc-shaped fan blade 2. When the fixed circular plate 8 rotates, the accumulated water will be guided to the end of the arc-shaped fan blade 2, and the accumulated water will be drained away by the high-speed rotating arc-shaped fan blade 2.

[0044] The waterproof cover 5 includes a truncated cone portion 9 and a cylindrical portion 10. The cylindrical portion 10 is arranged at the top of the truncated cone portion 9. The cylindrical portion 10 is sleeved on the rotating shaft 4 and is tightly attached to the outer wall of the fixed circular plate 8, thereby ensuring the sealing of the structure. The rotating shaft 4 is rotatably arranged on the fan bracket 1. The rain cover 6 is respectively installed at both ends of the fan bracket 1, thereby providing an additional protective barrier for the fan. It can be seen that there is a precise waterproof structure between the exposed arc-shaped fan blades 2 and the driving parts of the fan, which can prevent rainwater from intruding and actively drain the accumulated water to keep it dry.

[0045] In a preferred embodiment, the blade embedding groove 3 is also provided on the reinforced connecting plate 11 located between the two fixed circular plates 8, which supports the arc-shaped blades 2 together with the fixed circular plates 8, thereby effectively shortening the length of the arc-shaped blades 2 and significantly enhancing the connection strength between the fixed circular plates 8, thereby improving the overall stability and durability of the fan, reducing potential damage caused by vibration or external force, and extending the service life of the fan.

[0046] See also Figures 2 to 4The blade embedding groove 3 is cleverly arranged near the edge of the fixed circular plate 8, and the arc-shaped blades 2 are distributed around the edge, which optimizes the airflow path, improves the ventilation efficiency, and effectively reduces the noise level.

[0047] In addition, the present invention further provides a strip-shaped protective mesh cover 12, which is detachably mounted on the fan bracket 1, effectively blocking the intrusion of external foreign matter, protecting the fan from damage, and facilitating daily maintenance and cleaning by users.

[0048] The rain cover 6 in this embodiment is composed of a main panel 13, a side frame 14 and a top frame 15, which are closely connected by bending inwards. It can be understood that the rain cover 6 is an integrated structure, so it can form a nearly closed space, effectively isolate rainwater, and ensure that the fan can still operate stably in bad weather. In particular, the free end of the top frame 15 is folded inward to form a folded edge 16, and the fan bracket 1 provides a stable support platform for it.

[0049] It also includes an angle steel 17 and a first screw hole 18. The angle steel 17 is provided with the first screw hole 18, and the angle steel 17 is screwed to the front and rear sides of the fan bracket 1. The angle steel 17 and the first screw hole 18 provide a more stable solution for the connection between the fan bracket 1 and the external structure, significantly reducing the risk of displacement or damage of the fan due to vibration or external force. The side frame 14 is provided with a second screw hole 19, and the first screw hole 18 is arranged opposite to the second screw hole 19; the second screw hole 19 provided on the side frame 14 corresponds precisely to the first screw hole 18, so that the same screw can fix the waterproof cover and the angle steel 17 at the same time, which not only simplifies the installation process, but also significantly enhances the strength and stability of the overall structure. Preferably, the bending parts of the main panel 13, the side frame 14, and the top frame 15 all adopt a smooth transition design, which not only eliminates safety hazards, but also improves the practicality and aesthetics of the product.

[0050] In this embodiment, the rain cover 6 is also provided with a wiring hole 20, and the wiring hole 20 is used to install an aviation connector or an external power supply. In addition, a fan bearing is provided inside the rain cover, and the fan bearing is a stainless steel bearing. It can be understood that the fan bearing made of stainless steel has a high waterproof grade and can be regarded as a waterproof bearing.

[0051] In summary, the top-blowing energy-saving fan with a waterproof structure of the present invention, when the fan is started, the arc-shaped blade 2 starts to rotate under the drive of the rotating shaft 4, thereby generating airflow and promoting air flow; since the arc-shaped blade 2 is inserted into the blade embedding groove 3, and the ends are respectively extended from the blade embedding groove 3 to the outer wall of the fixed circular plate 8; the cylindrical portion 10 of the waterproof cover 5 is sleeved on the rotating shaft 4 and is close to the outer wall of the fixed circular plate 8, and a plurality of drainage grooves 7 are radially arranged on the outer wall of the fixed circular plate 8, which can guide the accumulated water to the end of the arc-shaped blade 2 when the fixed circular plate 8 rotates, and the accumulated water is drained by the high-speed rotating arc-shaped blade 2, and the rain cover 6 can effectively block rainwater from invading the core driving part of the fan, which can effectively prevent water from accumulating inside the fan and causing damage, and at the same time, when the fan is running, it can effectively keep the inside of the body dry, thereby extending the service life of the fan. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
