The full-heavy tetraquarks [Formula omitted] and [Formula omitted] are systematically investigated within a quark model. The meson-meson structure, diquark-antidiquark structure and K-structure are considered in this work. There is no bound state for [Formula omitted] and [Formula omitted] systems in [Formula omitted] and [Formula omitted] channels. However, for [Formula omitted] system, three possible resonance states with energy of [Formula omitted], [Formula omitted] and [Formula omitted] are found in [Formula omitted] and [Formula omitted], respectively, and their decay width [Formula omitted] are 6.7-8.4 MeV, 1.4-7.2 MeV and 9.1-11.1 MeV. For [Formula omitted] system, there also exist three possible resonance states with energy of [Formula omitted], [Formula omitted] and [Formula omitted] in [Formula omitted] and [Formula omitted], respectively, and the decay widths [Formula omitted] of them are 2.2-6.1 MeV, 2.2-6.9 MeV and 5.3-8.5 MeV. [Formula omitted] and [Formula omitted] systems will have the same results as [Formula omitted] and [Formula omitted], respectively. These full-heavy resonance states are worthy to be searched in the future experiments.
