工具篇31-平價吹風機開箱測試 (Tools 31-Unbox and Test Low Price Battery Powered Blower)

近年吹風機的家居使用普及了，價錢便宜了是一個原因
Recently, the domestic use of blowers at home is become more popular. The ever-lowering price is probably the main reason
微形化及採用充電設計是另兩個吸引之處
Portability and being powered by battery are the other 2 attractions
這支不連電池不到100元的吹風機，採用仿電鑽樣式，比早期蝸牛扇形狀吹風機小
This blower without battery is priced at less than a hundred dollars. It stimulates the design of the drill which is smaller than the centrifugal fan
兼容牧田電池，這個價錢，做工不算太差了
It uses Makita 18v battery pack. We admit that the buildup is not bad with respect to its price
塑料的強度要用破壞性測試，這個我們不做了
The strength or quality of the plastic is unknown but we won't test it
究竟表現如何，我們做個風速的測試
We gonna test its wind speed
由於風壓和風速成正比，我們將這吹風機和蝸牛扇及有線的空氣壓縮機比較
Since the wind pressure is positively related to the speed, we test the blower with the centrifugal type blower and the 220v air compressor
我們挑一個中間口徑的噴咀，用一塊6.0 Ah的電池，風速竟能達30M/s
To our surprise, the wind speed with a 6.0Ah battery can be as fast as 30m/s and more with a midum nozzle
偶然甚至衝過40m/s
It occasionally reaches 40m/s
試蝸牛扇，風速大概在27到34m/s之間
The centrifugal type can do 27-34m/s
體積大但風速反而弱，不過蝸牛扇的好處是能做到扇風分離
Though it is bigger the wind seems to be weaker. However, we must clarify that the centrifugal fan is able to create a separate airflow off the fan motor and blade
若在帶有可燃氣體的地方作通風用，直吹的風扇便不適宜
it is thus safe in the environment where inflammable gas is present
最後看正式的工業用壓縮機，氣壓設定在100psi左右，結果亦非常意外
At last, we test the traditional air compressor of which the pressure is set at about 100psi
風扇速大致和蝸牛扇吹風機持平，都是在30m/s上下變化
To our surprise again, it only makes 30m/s, no way to surpass 40m/s
怪不得已有電池推動的便攜壓縮機推出，只是體積受氣缸限制，無法縮小
No wonder portable air compressor is technically feasible and some models have been released yet the cylinder prevents further downsizing of the device
然而便攜性已提高很多
Anyway, the portability has been greatly improved
