Air-mode fan

Abstract

The invention discloses an air-mode fan which comprises a motor, an impeller, an air inlet, a wind outlet, a left tank and a right tank. The impeller is driven by the motor, a side of the left tank is rotationally connected with a side of the right tank, the left tank and the right tank can be closed with each other, latch components and matched lock components which can be locked with one another are arranged on the left tank and the right tank, the air inlet and the wind outlet are formed in the left tank, a large wind outlet cover and a small wind outlet cover which are matched with the wind outlet are arranged in the left tank, a middle support plate is arranged on the right tank, the motor is penetratingly arranged in a hole in the center of the middle support plate and is fixedly connected with the middle support plate, the impeller is arranged on the right side of the middle support plate, and a controller and a display device are arranged on the middle support plate. The air-mode fan has the advantages that the air-mode fan is provided with the tanks which are convenient to open, and accordingly is convenient to repair and maintain; the air-mode fan is provided with the built-in large wind outlet cover and the built-in small wind outlet cover, and the specifications of the wind outlet covers can be selected by users according to requirements, so that the applicability of the fan can be improved.

Description

technical field [0001] The present invention relates to an air blower required for blowing air patterns. Background technique [0002] At present, the blowers used on the air molds on the market are all single-layer plastic or iron-shell blowers made of AC induction motors. The disadvantages of high cost and short service life result in very limited use of the product and are not suitable for inflatable products. [0003] Generally, the inflatable products that use this type of fan are located far away from the power supply. Traditional fans are often caused by the poor quality of the outdoor power supply, insufficient voltage, too far from the power supply, and too thin wires, resulting in insufficient rotation speed, resulting in insufficient product air pressure. Insufficient bearing capacity, it cannot be used normally, and because the appearance is made of a single-layer iron shell or a single-layer plastic material, it has poor performance in terms of leakage, water r...

AI Technical Summary

Problems solved by technology

[0002] At present, the blowers used in the air model on the market are all single-layer plastic or iron shell blowers made of AC induction motors, which have low efficiency, large starting current, high noise, heavy weight, fixed speed, wind pressure, wind speed, and maintenance. The disadvantages of high cost and short service life lead to very limited use of the product and are not suitable for inflatable products

[0003] Generally, the inflatable products that use this kind of fan are located far away from the power supply. Traditional fans often have insufficient speed due to poor quality of outdoor power supply, insufficient voltage, too far away from the power supply, and too thin wires, resulting in insufficient air pressure of the product. Insufficient bearing capacity, can not be used normally, and because the appearance is a single-layer iron shell or single-layer plastic material, the performance in terms of leakage, water resistance and noise is poor. When the inflatable product is old, it is often necessary to add more fans, resulting in waste of fans and energy , also causes the load on the power supply to increase, and this fan is a country with a fixed speed of 220V50HZ, its speed can only reach 2850 rpm, and its speed can only reach 3250 rpm at 110V60HZ, the manufacturer can only adapt according to the size of the impeller Sexual deployment, voltage and frequency will have a destructive impact on this fan, and the general AC induction motor will cause the blades to rotate in the reverse direction when the wind is reversed. Instantaneous power failure often leads to reverse and cannot be inflated, which is very dangerous in use.
