[0003] At present, the foot bath ware circuit board bin is generally sealed waterproof by sealing ring, foamed sponge rubber, glue sealing etc. The sealing ring is generally divided into upper and lower sealing and side sealing. The upper and lower sealing generally utilizes upper and lower shells, and O-shaped ring is arranged between the shells, and the O-shaped ring is extruded in the upper and lower shell assembly direction to realize sealing effect. The side sealing generally extrudes O-shaped ring in the direction perpendicular to the upper and lower shell assembly direction to realize sealing effect.

[0004] The related technology in the above has the following defects:

[0005] Upper and lower sealing: the O-shaped ring is extruded by the upper and lower shells, and the upper and lower shells have a large reaction force in the assembly direction, and a strong fastening force is required, generally requiring screw fastening. The disadvantage is that locking screw can damage the product appearance. If fastening by means of buckle position etc. is used, the compression amount of the O-shaped ring cannot be guaranteed, and water leakage etc. can easily occur.

[0006] Side sealing: the O-shaped ring is extruded by the side of the upper and lower shells, and the upper and lower shells have no reaction force in the assembly direction, and a strong fastening force is not required, generally being buckled by buckle position, and the product appearance is not damaged. The disadvantage is that when assembling, the upper shell is extruded from the side of the O-shaped ring, and at this time, the O-shaped ring is easy to be twisted or damaged, causing sealing failure.

[0009] Further, the inner side of the sealing ring is provided with a flange, the flange and part of the V-shaped sealing ring form an installation groove, the opening of the installation groove is consistent with the opening direction of the V-shaped sealing ring, the first component is provided with a ring of first rib position at the position corresponding to the installation groove, and the sealing ring is clamped on the first rib position through the installation groove.

[0010] Further, the groove depth of the mounting groove is greater than the depth of the V-shaped portion of the sealing ring, and the first rib position extends to the groove bottom of the mounting groove.

[0011] Further, the groove wall of the mounting groove is in contact with the first rib position to form a sealing surface.

[0012] Further, the second component is provided with a second rib position at the position corresponding to the first rib position, and the second rib position and the first rib position extrude the turned edge when the second component is assembled with the first component, and a seal is formed between the second rib position and the turned edge.

[0013] The beneficial effects of the utility model are embodied in:

[0014] The utility model discloses, through extruding one side of the sealing ring of the second component, the sealing ring is deformed, at this time, one side of the sealing ring and the second component form a seal, and the other side of the sealing ring and the first component also form a seal, and because the relative position of the first component and the second component is determined, the deformation amount of the two sides of the sealing ring is determined, and water leakage is not easy to appear, and the design that one side of the sealing ring is deformed inward to make room can effectively improve the problem that the sealing ring is easy to twist and break when sealing, and assembly is more convenient.
