The contributions for the kaon pair from the intermediate states
and
in the decays
,
, and
are analyzed within the perturbative QCD factorization approach. The decay amplitudes for all concerned decays in this work are dominated by the factorizable Feynman diagrams with the emission of the kaon pair, and the charged ρ mesons should be of great importance in the
channel of the related three-body B decays. Moreover, these quasi-two-body decays are CKM-favored, and the relevant branching ratios are predicted to be in the order of
, which have the potential to be measured by experiments. It is also shown that the contributions of the subprocesses
for the three-body B meson decays are considerable according to the total three-body branching fractions presented by Belle. Therefore, the decays
,
, and
can be employed to study the properties of
and
in the LHCb and Belle-II experiments.
