With summers getting hotter every year, keeping your armpits dry is quite the challenge. While many of use still rely on deodorants, the quirky Japanese have come up with a high-tech alternative worthy of their reputation for crazy inventions – clip-on armpit fans.

如今夏天一年比一年热，要保持腋窝干爽是个相当大的挑战。许多人还在依赖除臭剂，另类的日本人已经想出了一种高科技替代品，一个名副其实的疯狂发明——夹在腋下的风扇。

Developed by Japanese gadget maker Thanko, the Waki no Shita Kura (Japanese for Under the Armpit Cooling Device) is a small fan that clips to your sleeve to deliver cooling blasts of air to your armpits.

由日本小型装置制造商Thanko开发，Waki no Shita Kura（该腋下降温装置的日语发音）是一个可以夹在袖子上的小风扇，把阵阵凉风吹到你的腋下。

The device is powered by three AAA batteries and can keep your armpits nice and dry for five to nine hours, depending on which of the three speeds you use. If you want to stay cool for longer you can connect the fan to your PC or a separately purchased battery pack with the included micro USB cable.

该装置由三节AAA电池供电，可以保持腋下五到九小时的干爽，持续时间长短取决于你对三种风力大小的选择。如果你想保持更长时间的干爽，可以将其连接到笔记本电脑上，或者连接到单独购买的蓄电池组上，该电池组包含了数据线。

Thanko claims the armpit fans are very light (30g/1 oz) and silent enough to use even in a crowded, so you shouldn't have to worry about attracting unwanted attention with your buzzing armpits.

Thanko宣称腋下风扇非常轻巧（重30g或1盎司），并且即使在拥挤的人群中使用也足够静音，所以你不必担心嗡嗡作响的腋窝会引起不必要的注意。

The fan is also very small (60 x 65 x 15mm) and thanks to the clip-on design it can also cool your chest area: just clip it to the front of your shirt and it will keep your torso and neck dry.

这个风扇也很迷你（60×65×15mm），而且多亏其可夹式设计，它还可以为你的胸部降温：只需将其夹在你的衬衫前面，就能保持躯干和颈部的干爽。

Japan Trend Shop has the Thanko Under the Armpit Cooling Device priced at $24, but you'll probably need to buy two of them, unless you're planning on alternatively using it on your armpits. So $48 on a device that probably works. I'd say deodorant is the safer and cheaper choice, but then again this thing is worth it just for the novelty of it.

日本新奇物品商店将Thanko的腋下降温装置定价为24美元，不过你可能需要买两个，除非你打算在两边的腋下交替使用一个。所以花费48美元购买这个装置还是可行的。我想说除臭剂是更安全、更便宜的选择，但话说回来，仅为其新奇性购买这个小物件也是值得的。

When it comes to weird Japanese inventions, I'd say the armpit fan is pretty low on the list, at least compared to other wacky inventions we've featured throughout the years. Let's remember this creepy hugging chair for the lonely, the speech jammer that stops people from talking or this creepy facial exercising device that Cristiano Ronaldo wouldn't even use, even though he was supposed to promote it. Oh, and I had almost forgot the Necomimi, wearable cat ears and tail controlled by brainwaves.

说到日本的奇葩发明，我觉得腋下风扇简直是小巫见大巫，至少与我们多年来精选的其他雷人发明相比还算正常。让我们回忆下：为孤独者发明的、令人毛骨悚然的拥抱椅，让人暂时闭嘴的弹话枪，或那个可怕的面部锻炼神器，即使该为其做宣传，克里斯蒂亚诺•罗纳尔多都不愿使用。哦，我差点忘了猫的秘密（智能意念猫耳朵），戴上以后猫耳朵和尾巴将受到脑电波的控制。
