Abstract: A light-emitting device including a casing with a light-transmitting port; a light source disposed inside the casing; and a casing cover disposed in the light-transmitting port. The casing cover having an outer peripheral cover portion with an opening; an inner peripheral cover portion located in the opening; a light-transmitting gap formed between the inner peripheral cover portion with the outer peripheral cover portion; and a connecting rib spanning the light-transmitting gap to connect the outer peripheral cover portion with the inner peripheral cover portion. The connecting rib includes a concave portion extending toward an inside of the casing and configured to allow light from the light source to pass through.

Abstract: Provided is an ion generating apparatus, including a housing and an ion generating unit. A waterproof part is provided below an air outlet. The waterproof part includes a discharge port penetrating the waterproof part and in communication with an inside of the housing, and a guide part having a receiving space for receiving a liquid flowing in from the air outlet and guiding the liquid to the discharge port while bypassing an ion exhaust port. By providing the waterproof part below the air outlet to receive the liquid flowing in from the air outlet, the ion generating apparatus may not only prevent the liquid from entering the ion generating unit through the ion exhaust port to affect an ion generation, but also allow a liquid entering the inside of the housing to flow out of the housing along a path that does not come into contact with an electrical component.

Abstract: The present disclosure relates to a light-emitting device, including: a casing provided with a light-transmitting port; a light source disposed inside the casing; and a casing cover covering the light source, wherein the casing cover is configured to be disposed in the light-transmitting port to cover the casing; wherein the casing cover includes: an outer peripheral side cover portion provided with an opening; an inner peripheral side cover portion located in the opening, wherein a light-transmitting gap is formed by spacing the inner peripheral side cover portion with the outer peripheral side cover portion; and a connecting rib configured to span the light-transmitting gap, and connect the outer peripheral side cover portion with the inner peripheral side cover portion; wherein the connecting rib is bent toward an inside of the casing to form a light-transmitting concave portion.
