一种浴室灯
By incorporating inner mounting brackets and raised steps in the light guide cover within the bathroom light, combined with snap-fit connections in the transparent outer cover, a double-sealed structure is formed. This solves the problems of moisture intrusion causing circuit board dampness and component corrosion, thereby improving sealing reliability and service life.

AI Technical Summary
The existing bathroom light has an inadequate sealing structure, which allows moisture to enter the light fixture, causing problems such as circuit board dampness, component corrosion, decreased insulation performance, and shortened lifespan.
The bottom shell is fitted with a buckle on the inside and a raised step on the light guide inner cover. Combined with the buckle connection between the transparent outer cover and the light guide inner cover, a double sealing structure is formed by the combined action of the bottom shell, the light guide inner cover and the transparent outer cover. The waterproof rubber ring is compressed stepwise during the assembly process to achieve precise positioning and double sealing.
It significantly improves the sealing reliability and service life of the lamps in high humidity environments, prevents moisture intrusion, avoids circuit board dampness and component corrosion, and is easy to disassemble and maintain.

Abstract
Claims
1. A bathroom light, comprising a base shell (1), a light source assembly (6), a light guide inner cover (8), and a transparent outer cover (9), characterized in that: The bottom shell (1) is provided with a fastener (12) on the inner side. The light guide inner cover (8) is fitted inside the bottom shell (1). The light guide inner cover (8) is provided with a raised step (82) that cooperates with the fastener (12). The light guide inner cover (8) includes an annular boss (80) located in the middle. The bottom of the annular boss (80) extends downward to form an annular shell (85). The raised step (82) is located on the outer surface of the annular shell (85) and is stepped. A waterproof rubber ring (4) is installed between the bottom sides of the annular boss (80) and the raised step (82). The raised step (82) is engaged with the lower part of the fastener (12) on the bottom shell (1). The transparent outer cover (9) is detachably connected to the light guide inner cover (8) by a snap-fit structure, and the waterproof rubber ring (4) is further compressed during the assembly process to form a double sealing structure formed by the combined action of the bottom shell (1), the light guide inner cover (8) and the transparent outer cover (9).
2. The bathroom light according to claim 1, characterized in that: The inner side of the bottom shell (1) is alternately provided with a first thickening layer (10) and a second thickening layer (11). The thickness of the first thickening layer (10) is less than the thickness of the second thickening layer (11). The fastener (12) is formed on the inner side of the first thickening layer (10) and is used to support the waterproof rubber ring (4). The top of the first thickening layer (10) and the second thickening layer (11) is a sloping structure, which provides space for the compression deformation of the waterproof rubber ring (4).
3. The bathroom light according to claim 2, characterized in that: The annular boss (80) is provided with an arc-shaped groove (83) formed by downward indentation, and the edge of the transparent cover (9) is provided with a plurality of arc-shaped protrusions (91) arranged circumferentially, and each arc-shaped protrusion (91) has a barbed elastic latch (92) extending from the top of its top. The arc-shaped protrusion (91) is used to insert into the arc-shaped groove (83), and the elastic latch (92) slides into the arc-shaped mounting groove (81) that communicates with the arc-shaped groove (83) and is snapped onto the arc-shaped protrusion (811) set in the arc-shaped mounting groove (81), thereby realizing the self-locking connection between the transparent outer cover (9) and the light guide inner cover (8).
4. The bathroom light according to claim 3, characterized in that: The waterproof rubber ring (4) is an annular silicone rubber sealing ring, which is installed between the bottom shell (1) and the light guide inner cover (8). It is gradually compressed during the assembly of the transparent outer cover (9) to generate radial and axial double sealing forces.
5. The bathroom light according to claim 1, characterized in that: The bottom shell (1) is provided with a support, mounting groove and fixing hole for mounting the light source assembly (6). The bottom of the light source assembly (6) is equipped with a heat sink (5) and the front of the light source assembly (6) is equipped with a lens (7). The light guide inner cover is snapped into the bottom shell (1) and the transparent outer cover (9) is snapped into the light guide inner cover.
6. The bathroom light of claim 5, wherein: An aluminum sheet (2) is installed inside the bottom shell (1), and a terminal block (3) is installed on the aluminum sheet (2). Both the bottom shell (1) and the aluminum sheet (2) are provided with through holes.
7. The bathroom light of claim 3, wherein: A socket (13) is formed in the downward groove on the top surface of the second thickened layer (11). A pin hole (84) is formed by a downward recess on the annular boss (80). A horizontal post is provided in the pin hole (84) and a pin (88) is provided with a pin hole (84) and a socket (13).
