When the contact portion 330 moves toward or away from the eyeball of the user, the relatively closed state between the wrapping portion 332 and the periphery of the eyeball of the user helps the eyeball of the user slightly move back and forth along with the contact portion 330, thereby achieving the effect of helping the eyeball to move.

In one embodiment, the thickness of the central portion 331 of the contact portion 330 is greater than that of the edge portion thereof, and since the pressure applied to the central portion 331 when the air chamber is inflated is greater than that applied to the edge portion, the central portion 331 is deformed to a greater extent, and the thickness of the central portion 331 is increased, the central portion 331 is effectively prevented from being excessively deformed, thereby preventing the user's eyeball from being broken or excessively pressed. The thickness of the central portion 331 can be set as appropriate, and can be either a uniform thickness or a graded thickness.

In another embodiment, as shown in fig. 7, the close-coupled casing 500 is still a part of the first casing 100, and is integrally formed with or fixedly connected to the first casing 100, the casing edge 510B is also a first connecting portion, the projecting direction of the casing edge 510B is opposite to the second connecting portion 210 of the second casing 200, the third connecting portion 310B forms a half-wrapping to the casing edge 510B, the first edge 311B of the third connecting portion 310B is located on the upper side of the casing edge 510B, the second edge 312B is located on the lower side of the casing edge 510B, and the second connecting portion 210 and the casing edge 510B (the first connecting portion) are hermetically connected through the third connecting portion 310B.

In some embodiments, the close housing 500 is a part of the first housing 100, and the first housing 100 and the second housing 200 are hermetically connected by the third connection portion 310. In other embodiments, the close-coupled housing 500 is fixedly connected or detachably connected to the first housing 100, and the close-coupled housing 500 is hermetically connected to the second housing 200 through the third connection portion 310.

Because the first recess 301 has a large-angle bending shape, when the pressure in the air chamber is different from the external atmospheric pressure (air inflation or air exhaust), the first recess 301 is easy to deform to cause air leakage, and the diaphragm 340 plays a role in preventing the first recess 301 from air leakage due to large-amplitude deformation. The shape of the diaphragm 340 is not particularly limited as long as the first recess 301 is not largely deformed as much as possible. In some embodiments, the upper end 341 of the diaphragm 340 has 1 or more than 1 upper connection with the plenum sidewall 320.
