Description

Technical Field

[0001] This utility model relates to the field of electric light source technology, and in particular to ultraviolet lamps. Background Technology

[0002] Existing ultraviolet lamps include ultraviolet filaments, quartz lamp tubes with the ultraviolet filaments housed within a cavity, and lamp holders that enclose the ultraviolet filaments within the quartz lamp tubes. This technology relies on the lamp holders to enclose the ultraviolet filaments within the quartz lamp tubes. These ultraviolet lamps are mass-produced general-purpose ultraviolet lamps in factories to effectively reduce manufacturing costs. As they are general-purpose products, the connectors between the filaments and the power cords are exposed and cannot be used for immersion in water. Summary of the Invention

[0003] The purpose of this invention is to provide a UV lamp that can use a common and inexpensive UV lamp, and at the same time, has a simple structure, good sealing performance, and can be used submerged in water.

[0004] The ultraviolet lamp of this utility model is implemented as follows: it includes a general-purpose ultraviolet lamp, a silicone seat with a silicone plug, and a quartz tube with one end blind and the other end open. The lamp holder of the general-purpose ultraviolet lamp is inserted into the silicone plug fixed in the silicone seat. The power wire connected to the power connector on the lamp holder of the general-purpose ultraviolet lamp is sealed and passes out of the silicone seat. The quartz tube is fitted onto the general-purpose ultraviolet lamp. The silicone plug is sealed and embedded into the quartz tube from the open end, so that the open end of the quartz tube is sealed against the silicone seat.

[0005] The invention employs a silicone plug sealing structure, utilizing the superior sealing properties of silicone to seal a universal UV lamp inside a quartz tube. Simultaneously, the power cord with an insulated sheath connects to the universal UV lamp connector and passes through the silicone seat in a sealed manner. This ensures that even when the device is immersed in water, there will be no leakage.

[0006] Preferably, the silicone plug has two stages, with the diameter of the top silicone plug being smaller than the diameter of the root silicone plug connected to the silicone seat. Because one end of the quartz tube is blind, inserting the silicone plug reduces the volume of the quartz tube and increases the air pressure. This air pressure can hinder the silicone plug from being fully inserted into the quartz tube. A two-stage silicone plug is used: the diameter of the top silicone plug is smaller than the diameter of the root silicone plug connected to the silicone seat, resulting in a slightly lower sealing force. The high-pressure gas inside the quartz tube can overcome this sealing force and escape between the quartz tube and the top silicone plug, allowing the silicone plug to be smoothly inserted into the quartz tube while maintaining a certain sealing force. Finally, the large diameter of the root silicone plug ensures sufficient sealing force, preventing water from seeping into the quartz tube when immersed in water, as the water pressure cannot overcome the sealing force. Because the root silicone plug can be relatively thin, the insertion depth into the quartz tube is small, and the increase in air pressure due to the reduced volume inside the quartz tube is not significant, ensuring a stable seal for the silicone plug.

[0007] Preferably, an adhesive is provided between the silicone plug and the quartz tube wall, and between the silicone seat and the open end face of the quartz tube, to ensure that the silicone seat with the silicone plug is fixedly connected to the quartz tube and to prevent the compressed air inside the quartz tube from pushing the silicone plug out of the quartz tube.

[0008] Preferably, the universal UV lamp is connected to a positioning bracket at its top. The shape of the positioning bracket matches the top of the inner cavity of the quartz tube, and the shape of the positioning bracket around its perimeter matches the cross-sectional shape of the inner wall of the quartz tube. When the universal UV lamp with the positioning bracket is inserted into the quartz tube, the positioning bracket guides the universal UV lamp and prevents it from shaking. At the same time, with the positioning bracket in place, the silicone plug can be smoothly inserted into the quartz tube, fixing the universal UV lamp inside the quartz tube. With the cooperation of the positioning bracket and the silicone plug, the universal UV lamp is guaranteed not to shake.

[0009] Compared with existing technologies, this invention has the advantages of using universal and inexpensive UV lamps, having a simple structure, good sealing, and being able to be used submerged in water. Attached Figure Description
