A high-efficiency mixed-flow fan

technical field

The utility model relates to the technical field of mixed-flow ventilators, in particular to a high-efficiency mixed-flow ventilator.

Background technique

The mixed flow fan is a fan between the axial flow fan and the centrifugal fan. It looks more like a traditional axial flow fan. The impeller of the mixed flow fan makes the air move both centrifugally and axially, and the movement of the air in the shell is mixed. Axial flow and centrifugal two forms of motion, so it is called "mixed flow", mixed flow (diagonal flow) fan, the wind pressure coefficient is higher than that of axial flow fan, and the flow coefficient is higher than that of centrifugal fan.

Most of the existing mixed-flow fans are fixed in the room, which reduces the flexibility and the efficiency is not high, and during use, the bottom of the mixed-flow fan and the ground are prone to vibration and noise. At the same time, its own operation will also make a lot of noise, causing interference to the surrounding environment. For this reason, we propose a high-efficiency mixed-flow fan.

The noise generated by the ventilator body can be reduced and blocked by the provided sound-absorbing baffle, thereby reducing the noise interference of the ventilator body.

In a further technical solution, sound-absorbing cotton is fixedly installed on one side surface of the sound-absorbing baffle.

The sound-absorbing cotton provided can preliminarily eliminate the noise generated by the fan body itself, reducing the range of noise diffusion.

In a further technical solution, a protective net is fixedly installed at one end of the ventilator body.

The protective net improves the protection of the inside of the ventilator body, reduces damage to the inside caused by external objects, and increases the cost of later maintenance.

In a further technical solution, one end of the ventilator body is fixedly connected with a connecting pipe, and the connecting pipe is a hose.

The use range of the device is improved through the provided connecting pipe, and the use efficiency is improved.

In a further technical solution, the surface of the fan body is fixedly mounted with a shock-absorbing plate, and the shock-absorbing plate and the surface of the fan body are fixedly connected by screws.

The vibration-absorbing plate reduces the noise generated by the fan body itself due to the vibration, and improves the comfort of the device.

The beneficial effects of the utility model are:

1. Adopting the high-efficiency mixed-flow fan of the present utility model, the overall flexibility of the device is improved through the provided base, universal wheels and push handles, which is convenient to move according to needs, and the high efficiency of the use of the device is improved. When moving When it is in a proper position, the fixed block and the ground can be connected with screws through the provided threaded rod, fixed block and threaded hole, thereby further improving the overall stability of the device. Reduce the noise interference caused by the vibration generated by the fan body itself.

2. With the high-efficiency mixed-flow fan of the present invention, the noise generated by the fan body can be reduced and blocked by the sound-absorbing baffle provided, thereby reducing the noise interference of the fan body. It can preliminarily eliminate the noise generated by the fan body itself, reducing the scope of noise diffusion.
