[0016] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0017] Please refer to Figures 1-4 , a sand blasting and teeth cleaning machine with anti-blocking function of the utility model includes a spray head 1, a spray pipe 2, a sand box assembly 3 and a water and gas inlet pipe 4 which are connected in sequence. The sand box assembly 3 includes a sand box seat 5 and a sand box. The sand box is arranged on the sand box seat 5. The sand box includes a box body 6 and a box cover 7. A jacket 6.1 is arranged on the box body 6. One end of the sand box seat 5 is connected to the spray pipe 2 and an air outlet pipe 8 and a water outlet pipe 9 are arranged inside.
