In order to make a further confirmation about the assignments of the excitedbottom and bottom strange mesons $B_{1}(5721)$, $B_{2}^{*}(5747)$,$B_{s1}(5830)$, $B_{s2}^{*}(5840)$ and meanwhile identify the possibleassignments of $B_{J}(5840)$, $B_{J}(5970)$, we study the strong decays ofthese states with the $^{3}P_{0}$ decay model. Our analysis support$B_{1}(5721)$ and $B_{2}^{*}(5747)$ to be the $1P_{1}'$ and $1^{3}P_{2}$assignments and the $B_{s1}(5830)$, $B_{s2}^{*}(5840)$ to be the strangepartner of $B_{1}(5721)$ and $B_{2}^{*}(5747)$. Besides, we tentativelyidentify the recently observed $B_{J}(5840)$, $B_{J}(5970)$ as the $2^{3}S_{1}$and $1^{3}D_{3}$ states, respectively. It is noticed that this conclusion needsfurther confirmation by measuring the decay channel to $B\pi$ of $B_{J}(5840)$and $B_{J}(5970)$ in experiments.
