Using the chromomagnetic interaction Hamiltonian with proper account for the SU(3) flavor symmetry breaking, we have performed a schematic study on the masses of S-wave heavy tetraquarks as bqbq (q denotes u, d, s quark). It is found that the numeral results for bubd or bdbu with 1+ quantum number are 10612 MeV and 10683 MeV respectively, which are well compatible with the recent detected charged bottomonium-like Zb(10610) and Zb(10650). Theoretically, we also investigate the possible tetraquark states of 1++ and 2+ due to the charge conjugation as the potential candidates for the updating experiments.
