Sexual stimulation device

1. A sexual stimulation device, comprising:

a ring structure;

at least one first function member positioned at one side of the ring structure;

at least one second function member positioned at an other side of the ring structure; and

at least one battery arranged in the first function member and/or the second function member,

wherein the first function member and the second function member collectively comprise N stimulation sources, and wherein N is greater than or equal to 3;

wherein the at least one first function member comprises a proximal first function member and a distal first function member connected to the ring structure;

wherein the ring structure comprises a first sleeve and a second sleeve spaced from each other, the first sleeve being connected between the proximal first function member and the at least one second function member, and the second sleeve is connected to a bottom of the distal first function member and is adjacent to one end of the first sleeve.

2. The sexual stimulation device of claim 1 , wherein stimuli provided by the N stimulation sources comprise at least one of the following: mechanical stimulus, electrical stimulus and heating stimulus.

3. The sexual stimulation device of claim 2 , wherein the mechanical stimulus is at least one of the following: vibrating, swinging, twisting, buckling, slapping, extending-retracting and suctioning.

4. The sexual stimulation device of claim 1 , wherein the proximal first function member is provided with a first on/off key.

5. The sexual stimulation device of claim 1 , wherein a vibration stimulation source is arranged within the proximal first function member.

6. The sexual stimulation device of claim 1 , wherein a vibration stimulation source is arranged within the distal first function member.

7. The sexual stimulation device of claim 1 , wherein the distal first function member is provided with an electrical stimulation source.

8. The sexual stimulation device of claim 1 , wherein a diameter of the first sleeve is larger than a diameter of the second sleeve.

9. The sexual stimulation device of claim 1 , wherein the first sleeve is inclined backwards with respect to a longitudinal axis of the distal first function member.

10. The sexual stimulation device of claim 1 , wherein a top end of the second sleeve has a transition portion, and a width of the transition portion gradually increases from top to bottom.

11. The sexual stimulation device of claim 10 , wherein a front side and a rear side of the transition portion extend to side surfaces of the distal first function member, respectively.

12. The sexual stimulation device of claim 1 , wherein the at least one second function member comprises a proximal second function member for stimulating a testis and/or a perineum, and the proximal second function member is connected to the ring structure.

13. The sexual stimulation device of claim 12 , wherein the proximal second function member is provided with an on/off key.

14. The sexual stimulation device of claim 12 , wherein a vibration stimulation source is arranged within the proximal second function member.

15. The sexual stimulation device of claim 12 , wherein the at least one second function member further comprises a distal second function member configured for inserting into an anus, and the distal second function member being connected to one end of the proximal second function member away from the ring structure.

16. The sexual stimulation device of claim 15 , wherein a vibration stimulation source is arranged within the distal second function member.

17. The sexual stimulation device of claim 1 , wherein the at least one second function member comprises an anal plug for inserting into an anus, and the anal plug is connected to the ring structure through a connecting member.
