Fig. 1-3 show that the utility model provides an embodiment of a water-locking roller sponge forming die.

This lock water cylinder sponge forming die includes cylinder sponge cover 10 and fixes cylinder sponge support B at two fixed bolsters that cylinder sponge cover 10 axial direction central point put, left fixed bolster 21 and right fixed bolster 22 promptly, forms cylinder sponge shaping die cavity D between cylinder sponge cover 10 inner wall and the cylinder sponge B outside, cylinder sponge support B surface equals with the arbitrary radial distance of cylinder sponge cover 10 inner wall, and left fixed bolster 21 and right fixed bolster 22 are located respectively and are equipped with the lock water structure between cylinder sponge support B and the cylinder sponge cover 10 inner wall.

Specifically, a plurality of grooves (not shown in the attached figures) are distributed on the surface of the roller sponge support B, so that the combination tightness of the formed roller sponge and the roller sponge support B can be improved. The water locking structure comprises inclined planes 213 which are respectively arranged at the end parts of the left fixing support 21 and the right fixing support 22 in the circumferential direction. The left fixing bracket 21 is provided with a first fixing part 211 fixed with the roller sponge bracket B, at least one step is arranged between the first fixing part 211 and the second fixing part 212, the edge of the step is set as an inclined surface 213, namely the inclined surface 213 is arranged at the end part of the fixing bracket close to the circumferential direction of the die cavity, the second fixing part 212 is fixed with the roller sponge sleeve 10, and the die cavity D is formed between the second fixing part 212 and the first fixing part 211. The right fixing bracket 22 may have the same structure, and particularly, the first fixing portion 211 and the second fixing portion 212 have the same structure. The inclined plane 213 is annularly distributed on the left fixing support 21 and the right fixing support 22, so that when the sponge is formed, water locking structures as shown in fig. 3 can be formed at two ends of the roller sponge, and the inclined plane 213 can be enlarged with the contact surface between the roller sponge and the shell after the roller sponge is installed, so that the water locking effect is increased, the watertight path length is effectively increased, and the leakage of cleaning liquid can be effectively avoided.

As shown in fig. 4-11, the water locking structure may include a guide groove 214 disposed between the roller sponge support B and the inner wall of the roller sponge sleeve 10 in the circumferential direction, that is, the water locking structure includes a guide groove 214, and the guide groove 214 is disposed in the circumferential direction of the end surface of the fixing support and between the roller sponge support B and the roller sponge sleeve 10. The channel 214 is at least one annular channel. When the number of the annular guide grooves is two or more, each annular guide groove is concentric. The annular guide groove is gradually increased from the bottom to the opening along the cross section perpendicular to the diameter. Owing to set up like this and can be more easily to outside deformation when tip and casing contact, can upwards promote the lock water face, moreover and the casing between the massage power littleer. When a plurality of annular guide grooves can provide better water locking effect. The inclination angle of one side of the annular guide groove, which is close to the edge, is smaller than the other side, so that the water locking structure formed by the annular guide groove can be ensured to deform outwards all the time when being installed, and the water locking effect is improved. According to the needs, the cross section of the annular guide groove along the direction vertical to the diameter is in a trapezoid shape, a triangle shape or a strip shape, so that the water locking structure formed by the annular guide groove can have a better water locking effect.

As shown in fig. 12-15, an extension groove 101 is provided at the position where the inner wall of the roller sponge case 10 is engaged with the fixing bracket B, and the extension groove 101 and the edge of the left fixing bracket 21 form a water locking structure, and since one side of the extension groove extends outwards, the extension groove is higher than the side of the roller sponge. When the installation, the extending groove 101 is deformed outwards, so that the water locking structure formed by the extending groove 101 is contacted with the shell, the water locking surface can be upwards lifted, namely, the water locking surface is higher than the surface of the roller sponge, thereby effectively locking liquid and avoiding the phenomenon of leakage from the side surface

The foregoing embodiments have been described in detail to illustrate the principles and implementations of the present application, and the foregoing embodiments are only used to help understand the method and its core idea of the present application. Meanwhile, a person skilled in the art should, according to the idea of the present application, change or modify the embodiments and applications of the present application based on the scope of the present application. In view of the above, the description should not be taken as limiting the application.
