  In this paper, under the illumination of thin disk accretion, we have
employed the ray-tracing method to carefully investigate shadows and rings of
the Kehagias-Sfetsos(KS) black hole in deformed Ho\v{r}ava-Lifshitz(HL)
gravity. The results show that the event horizon $r_+$, the radius $r_p$ and
impact parameter $b_{p}$ of photon sphere are all decreased with the increase
of the HL parameter $\omega$, but the effective potential increases. And, it
also turns out that the trajectories of light rays emitted from the north pole
direction are defined as the direct emission, lensing ring and photon ring of
KS black hole, on the basis of orbits $n = \phi/2\pi$. As black hole surrounded
by thin disk accretion, we show that the corresponding transfer functions have
their values increased with the parameter $\omega$. More importantly, we also
find that the direct emissions always dominate the total observed intensity,
while lensing rings as a thin ring make a very small contribution and photon
ring as a extremely narrow ring make a negligible contribution, for all three
toy-model functions. In view of this, the results finally imply that shadows
and rings as the observational appearance of KS black hole exhibit some obvious
interesting features, which might be regarded as an effective way to
distinguish black holes in HL gravity from the Schwarzschild black hole.
