Description

Technical Field

[0001] This utility model relates to the field of fan technology, and more specifically, to a safe and energy-saving fan. Background Technology

[0002] In recent years, fans, as common ventilation and cooling devices in homes and public places, have seen increasing attention paid to their safety and energy efficiency.

[0003] Traditional fans typically employ an open-blade design, which, while offering high airflow efficiency, poses significant safety hazards, especially for children. Children's strong curiosity and weak self-protection awareness make it easy for fingers or foreign objects to accidentally enter the rotating blade area, leading to pinching or other accidental injuries. Although some products on the market have incorporated protective nets to reduce the risk, the gaps in these nets may not completely prevent small objects (such as children's fingers or toys) from entering, and may also affect airflow efficiency. Furthermore, the motor design and blade structure of traditional fans are often not fully optimized, resulting in low energy utilization. Some electrical energy is converted into noise rather than effective airflow, increasing energy consumption and impacting user experience. Therefore, this study researches and improves upon existing structures to provide a safer and more energy-efficient fan with greater practical value. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a safe and energy-saving fan. It can place the drive motor at the front and the fan blades at the rear, so that when the fan blades rotate, the air can be drawn in through the air intake grille of the rear cover, and then expelled by a compression airflow through several air ducts set between the outer side of the mounting base and the inner side wall of the fixed base. This effectively reduces wind loss and energy consumption, and greatly improves the efficiency of airflow. At the same time, placing the fan blades at the rear can also improve the safety performance of use, and prevent small objects (such as children's fingers, toys, etc.) from accidentally entering the rotating blade area and causing pinching or other accidental injuries.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A safe and energy-saving fan includes a base, a gyratory seat at the top of the base, a front cover rotatably connected to the inner walls of the top two sides of the gyratory seat via a rotation damping shaft, a rear cover fixedly connected to one side of the front cover, a fixed seat installed inside the front cover, an mounting seat installed inside the fixed seat, several air ducts provided between the outer side of the mounting seat and the inner side wall of the fixed seat, a drive motor fixedly installed on the side of the mounting seat near the rear cover, a fan blade connected to the output shaft of the drive motor via a key, and a protective cover fixedly connected to the edge of the fixed seat near the rear cover.

[0007] Furthermore, a device mounting slot is provided on the side of the mounting base away from the rear cover, and a control motherboard is installed in the device mounting slot. A face mask is also fixedly connected to the side of the mounting base away from the rear cover.

[0008] Furthermore, an air inlet is provided on the side of the rear cover away from the front cover, and an air intake grille is installed inside the air inlet.

[0009] Furthermore, the protective cover has a frustum-shaped structure with openings at both ends, and the fan blades are located inside the protective cover.

[0010] Furthermore, a pendulum motor is installed inside the pendulum base, and the output end of the pendulum motor is fixedly connected to the top of the base by a key.

[0011] Furthermore, the fan blade includes a connecting seat mounted on the outer periphery of the output shaft of the drive motor. The connecting seat has several ventilation holes on the side near the rear cover, and several blades are mounted on the outer periphery of the connecting seat.

[0012] Furthermore, the control motherboard is electrically connected to both the drive motor and the gyratory motor via wires.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] This design places the drive motor at the front and the fan blades at the rear. When the fan blades rotate, they create a negative pressure at the rear cover, allowing air to be drawn in through the air intake grille of the rear cover and then expelled by compression through several air ducts set between the outer side of the mounting base and the inner side wall of the fixed base. This effectively reduces wind loss and energy consumption, and greatly improves the efficiency of air output. At the same time, placing the fan blades at the rear also improves the safety performance of use, preventing small objects, such as children's fingers or toys, from accidentally entering the rotating blade area and causing pinching or other accidental injuries.
