Floor fan capable of automatically adjusting height

Abstract

The invention discloses a floor fan capable of automatically adjusting the height. A counter weight base, a control box and a supporting table are included; the four corner positions of the lower endof the counter weight base are provided with storing grooves; electric telescopic rods are arranged in the storing grooves; and the lower ends of the electric telescopic rods are provided with a connection plate. The floor fan capable of automatically adjusting the height has the beneficial effects that by arranging the storing grooves and the electric telescopic rods, convenient and fast storingof universal wheels can be achieved, the counter weight base can be in contact with the ground after the floor fan is moved, and the stability of the floor fan is improved; by arranging an electric pushing rod, an ultrasonic distance measuring sensor, a microprocessor and a signal transceiver, automatic adjusting of the height of the floor fan can be achieved, tediousness of traditional manual adjustment is avoided, and the practicability of the floor fan is improved; and by arranging a temperature sensor and an infrared sensor, when an indoor temperature exceeds a set value and a person is nearby the floor fan, automatic starting of the floor fan is achieved, and the floor fan is more intelligent.

Description

technical field [0001] The invention relates to the technical field of floor fans, in particular to a floor fan whose height can be automatically adjusted. Background technique [0002] The main features of the floor fan are large air volume and low noise. In the hot summer, it is better to ventilate the room, prevent heatstroke and cool down, and improve the environment. It is safe to use the floor fan on the ground. Floor fans can be widely used in warehouses, workshops, restaurants, homes and other places of industrial and mining enterprises. [0003] The Chinese patent with the patent number CN201720277088.0 discloses a floor fan bracket and a floor fan, including a support seat and a telescopic rod arranged on the support seat, the telescopic rod is provided with a support device, and the support device includes lugs , a sliding sleeve, a support plate and a support rod, the support plate is provided with a remote control placement box and a wire storage device.

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned patent still has the following deficiencies in the process of use. First, it lacks a storage device, so that the floor fan cannot realize the convenient storage of the universal wheel after the movement is completed, thereby reducing the stability of the floor fan when it is working. Adjusting the height of the floor fan manually requires a lot of manpower, and the adjustment process is cumbersome, which reduces the practicability of the floor fan. In addition, there is a lack of temperature detection and infrared detection devices on the floor fan, which cannot be used when the floor fan is connected to an external power supply. The automatic start of the fan reduces the functionality of the floor fan, so there is an urgent need for a floor fan that can automatically adjust the height to solve the existing problems
