What's the question? Or what kind of question is this?
Any / all / every camera has DOF. Or more precisely, any / all / every lens
has DOF, since DOF is a characteristics of lens optics. And since any / all
/ every modern camera has lens, except pinhole camera, so what's the
question?
Oh, wait, the title question is: 哪个小的机器有 DOF? Answer: 有镜头的照相机
小机器有 DOF.

楼主其实想问的是哪个小DC有背景虚化的效果,
即大光圈,浅景深,突出主体,虚化背景,对吧?

Well, if that's the case, then the answer to the original question is almost
a no, since achieving "突出主体,虚化背景" requires large sensor and large
lens.
For example, for an 1/1.7" sensor, which is larger than most of P&S DC's 1/2
.3" sensor, it has a "focal length multiplier" of 4.6, so even with a
maximum aperture of F1.8, it's equivalent or effective aperture is about F8.
3, not much use for "突出主体,虚化背景".
Or, for Nikon / Sony APS-C type sensor, with a "focal length multiplier" of
1.5, if you use an F2.8 lens, the equivalent or effective aperture is
actually F4.2.
