[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a technical solution:

[0027] An oropharyngeal spreader for protecting teeth and gums comprises a fixed frame 1, a slide groove 2 is provided on the fixed frame 1, a moving rod 3 is slidably installed inside the slide groove 2, a tongue stopper 4 is fixedly installed on the moving rod 3, an arc frame 5 is fixedly installed on one side of the fixed frame 1, a filter screen 6 is provided on the arc frame 5, a compressed sponge 7 is fixedly installed on the filter screen 6, a water pipe 8 is provided on the arc frame 5, and the water pipe 8 is connected to an external water supply mechanism, which can be a water pump.

[0028] Specifically, the arc frame 5 is provided with a plurality of water outlets 9 , a cavity 10 is opened inside the arc frame 5 , a water inlet 11 is opened inside the arc frame 5 , the water pipe 8 is connected with the inside of the cavity 10 through the water inlet 11 , and the cavity 10 is connected with the water outlet 9 .

[0029] A moving block 12 is slidably installed inside the cavity 10 , and rubber pads 13 are fixedly installed at both ends of the moving block 12 . The rubber pads 13 correspond to the positions of the water inlet 11 in the cavity 10 .

[0030] In addition, a plurality of plug rods 14 are fixedly mounted on the filter screen 6, and a plurality of plug holes 15 are provided on the arc frame 5, and the plug rods 14 are plugged and matched with the plug holes 15.

[0031] It is worth noting that a plurality of first magnets 16 are embedded on the moving block 12 , and a plurality of second magnets 17 are fixedly mounted on the insertion rod 14 , and the first magnets 16 and the second magnets 17 are magnetically matched.

[0032] In addition, the end of the insertion rod 14 is in compression contact with the outer wall of the moving block 12 , and a spring 18 is fixedly mounted on the moving block 12 , and the other end of the spring 18 is fixedly connected to the inner wall of the cavity 10 .
