Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] like Figure 1 to Figure 7 The electric fan shown includes: a supporting column 1; a lifting structure, the lifting structure is movably arranged on the supporting column 1; a clamping structure, the clamping structure is arranged on the lifting structure, and the The clamping structure can be clamped and matched with the support column 1; the machine head 2, the machine head 2 is arranged on the lifting structure. When the height of the machine head 2 does not need to be adjusted, the clamping structure is clamped with the support column 1 to ensure the reliability of the height of the mac...

Abstract

The invention provides an electric fan. The electric fan comprises a supporting column, a lifting structure, a clamping structure and a fan head, wherein the lifting structure is movably arranged on the supporting column, the clamping structure is arranged on the lifting structure and can be matched with the supporting column in a clamping mode, and the fan head is arranged on the lifting structure. According to the electric fan, the clamping structure is arranged to clamp the supporting column, and after height adjustment of the fan head is completed, continuous work of a motor is avoided through clamping between the clamping structure and the supporting column, so that damage to the motor is avoided, and the precision and reliability of height adjustment of the fan head are guaranteed; and meanwhile, through rotation of a fan head fixing frame and a reset mechanism, a clamping groove fixing plate can clamp the supporting column according to needs, so that the reliability of height adjustment of the fan head is guaranteed.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to an electric fan. Background technique [0002] Most of the fans on the market currently adjust the height of the machine head manually, and most of them adjust the height by manually tightening the lifting fixing nut and locking the support rod to fix the height. In order to realize the automatic adjustment of the height of the machine head, there are The electric fan is driven by the gear driven by the motor, and the head is moved by the rotation of the gear, but when the head reaches the set position, it uses the torque of the motor to limit the gear so as to ensure that the head will not move relative to each other. Due to the certain quality of the machine head, in this solution, the motor needs to work continuously to generate torque to keep the gears from rotating, and the continuous operation will cause damage to the motor, making the machine head unable to adjus...
