After the technical scheme is adopted, the invention has the following advantages:

1. The main water passing channels are arranged at the joint of the annular connecting part and the bowl-shaped covering part, so that a large amount of water can be normally discharged, and the main water passing channels are provided with a plurality of main water passing channels which are arranged at intervals along the circumferential direction of the elastic anti-overflow cover, so that the anti-overflow water drinking cup can discharge water for drinking in the circumferential 360-degree direction; an auxiliary water passing channel is arranged between the inner through groove and the annular connecting part, and the auxiliary water passing channel is arranged against the inner wall of the inner through groove, so that liquid in the anti-overflow drinking cup can smoothly flow out, residues are not easy to form, and the utilization rate of the liquid is improved; meanwhile, as the outer diameter of the annular connecting part is smaller than the inner diameter of the inner wall of the inner through groove, a gap is also reserved between the annular connecting part and the limiting latch, so that all auxiliary water channels can be ensured to be communicated, and liquid residues are further avoided; and because the auxiliary water passing channel is formed by matching the annular connecting part with the water passing cavity, when the elastic overflow-preventing cover is detached from the support, the water passing channel is divided into two parts, so that the water passing channel can be thoroughly and conveniently cleaned, and the convenience of cleaning the overflow-preventing cover drinking cup is improved. Through setting up main water channel and supplementary water channel simultaneously, main water channel and supplementary water channel all communicate cup and appearance water cavity, when the liquid in the cup is great, main water channel and supplementary water channel go out water in step, realize normally a large amount of water that go out; when the main water channel is not used for discharging water, the residual liquid in the cup body flows out through the auxiliary water channel, so that the utilization rate of the liquid in the cup body is improved, and waste is avoided. If only the main water channel is arranged, the inlet position of the main water channel is higher than the inner wall of the through groove in the support, so that liquid is easy to remain in the cup body; if only set up supplementary water channel, because supplementary water channel passes through annular connecting portion and crosses the water cavity cooperation and forms, annular connecting portion need with spacing latch cooperation so its external diameter can't be too much smaller than the internal diameter of interior through groove inner wall for supplementary water channel's water area is not big, and the play water is slower.

2. The movable convex ring is clamped between the two convex rings through the clamping teeth, so that the detachable matching of the limiting clamping teeth and the annular connecting part is realized between the two clamping teeth, and the mounting is reliable and the dismounting is convenient.

3. The isomorphism sets up the latch and the bulge loop that a plurality of upper and lower settings set up and a plurality of upper and lower sets up, and when elasticity anti-overflow lid and support were in the cooperation state, latch and bulge loop interval joint have improved elasticity anti-overflow lid and support complex reliability.

4. Through set up in the breach of main water channel intercommunication on the bulge loop of top, under the prerequisite that does not influence elasticity anti-overflow lid and support cooperation reliability, increased the export of main water channel, the user of being convenient for also plays the effect of subtracting heavy simultaneously to the washing of elasticity anti-overflow lid.

5. The outer diameters of the convex rings are gradually reduced from top to bottom, and the whole elastic anti-overflow cover is approximately in a frustum shape, so that the annular connecting part can enter the limiting latch to be matched with the limiting latch more easily, and the elastic anti-overflow cover is more convenient to assemble and disassemble.

6. The elastic anti-overflow cover and the support can be matched between the convex ring and the support protrusion through the clamping teeth in a clamping manner, and meanwhile, the overall height of the elastic anti-overflow cover can be reduced, so that the anti-overflow water drinking cup is more portable.

7. The inclination of the upper inclined plane of the latch is larger than that of the lower inclined plane, the convex ring is convenient to clamp in by setting the inclination of the upper inclined plane larger, and the elastic anti-overflow cover is prevented from falling off by setting the inclination of the lower inclined plane smaller. The inclination of the inclined plane equals the inclination of the latch lower inclined plane on the bulge loop, and the inclination of the inclined plane equals the inclination of the latch upper inclined plane under the bulge loop for bulge loop and latch can cooperate reliable and stable.

8. The elastic anti-overflow cover and the support can be matched between the convex ring and the outer wall of the bowl-shaped cover part through the clamping teeth in a clamping manner, the structure is simple, the processing is convenient, and meanwhile, the integral height of the elastic anti-overflow cover can be reduced, so that the anti-overflow water drinking cup is more portable.

9. Through setting up the holding ring, when preventing excessively pressing elasticity anti-overflow lid, spacing latch misplaces with the cooperation of cyclic annular connecting portion, and whole elasticity anti-overflow lid subsides. The supporting ring is provided with a water passing groove communicated with the auxiliary water passing channel, so that the normal water outlet of the auxiliary water passing channel is ensured.

10. The radial length of the supporting ring is greater than that of the limiting latch, so that the supporting effect of the supporting ring on the annular connecting part of the elastic anti-overflow cover is guaranteed.

11. The side wall of the main water channel close to the bowl-shaped covering part is arranged in an outward inclined mode in a shape corresponding to the outer wall of the bowl-shaped covering part, and the side wall of the main water channel close to the annular connecting part is arranged vertically, so that the water outlet area of the main water channel is as large as possible, and the water outlet efficiency is improved.

12. The drinking edge is in an outward-expansion horn shape, the contact area between the drinking edge and the edge section can be increased, and the taper of the edge section is larger than that of the drinking edge, so that when the elastic anti-overflow cover is arranged on the support, the edge section deforms inwards and provides elasticity to compress the drinking edge, and the sealing effect of the water containing cavity is improved.

13. The outer diameter of the bowl-shaped cover part is larger than the inner diameter of the edge of the upper end of the support when the elastic anti-overflow cover and the support are in an unassembled state, so that the outer edge of the bowl-shaped cover part can cover the edge of the upper end of the support when the elastic anti-overflow cover and the support are in an assembled state, and the sealing effect of the water containing cavity is ensured.

14. Through setting up and dodging the groove, dodging the groove and crossing water chamber intercommunication, increase the water area of supplementary water channel to improve the play water efficiency of supplementary water channel.

15. The avoidance groove is communicated with the inner through groove and the outer groove, so that the water passing area of the auxiliary water passing channel is further increased.
