Description

Technical Field

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

[0002] Existing table fans typically have blades made of metal or plastic, requiring a dense protective mesh. This makes the fans less lightweight, and both the dense mesh and blades tend to collect dust, making them difficult to clean.

[0003] For example, patent document CN209129903U discloses a portable table fan, including a housing, a motor, and fan blades. The motor and fan blades are both located inside the housing, and the output end of the motor is fixedly connected to the fan blades. A connecting rod is detachably connected to the outer wall of the housing by a bolt No. 1, and rollers are rotatably connected to both ends of the connecting rod. The rollers are provided with rubber sleeves. A bracket is welded to the side of the housing opposite to the rollers, and a rubber pad is glued to the bottom of the bracket. A protective net is detachably connected to one side of the housing by a bolt No. 2, and a magnetic block and a sealing ring are respectively provided between the housing and the protective net.

[0004] For example, patent document CN104564726A discloses a rechargeable table fan, which mainly consists of a switch, a table fan, a battery, a power adapter, and a plug. The battery is installed inside the table fan and connected to the power adapter to store electrical energy.

[0005] Therefore, a table fan is proposed to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a table fan whose blades are made of EVA material, which is safe and easy to clean.

[0007] The technical solution adopted by this utility model to solve the problem is: a table fan, including: a body, the body including a column, a motor assembly at the top of the column, fan blades on the output shaft of the motor assembly, the fan blades being made of EVA material, a protective net and a circuit board, the protective net including multiple spokes; the spokes being made of metal, the spokes being electrically connected to the circuit board, and when the spokes are energized, the voltage not exceeding 10V and the current not exceeding 1A.

[0008] As a further improvement to the above technical solution, the protective net includes a support net and a front net. The support net is fixedly connected to the motor unit, and the front net is fixedly installed on the support net. The fan blade is located between the support net and the front net, and both the support net and the front net are connected with spokes.

[0009] As a further improvement to the above technical solution, multiple support legs are welded and fixed on the support mesh, and the support legs are fixedly connected to the motor unit by bolts.

[0010] As a further improvement to the above technical solution, multiple support rods are welded and fixed to the support net, and the support rods are fixedly connected to the front net.

[0011] As a further improvement to the above technical solution, the support rod is elastic, and a buckle is fixedly installed at the end of the support rod, which engages with the front grille.

[0012] The beneficial effects of this utility model are: the fan blades are made of EVA material, which is soft and has high safety. The protective net carries a slight current and can perform electrostatic dust removal to keep the fan blades relatively clean. When disassembling and cleaning, only the protective net can be removed and cleaned without disassembling and cleaning the fan blades. Attached Figure Description
