Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to an ultraviolet sterilization lamp. Background Art

[0002] Ultraviolet germicidal lamp (referred to as UV lamp in this article) is a common physical disinfection method in the field of water treatment. Its principle is to use ultraviolet rays to irradiate water bodies, destroy the nucleic acid structure of microorganisms, and thus kill or lose the ability to reproduce microorganisms. It can quickly and effectively kill bacteria, viruses, parasites and other microorganisms in water. Its sterilization rate can reach more than 99.9%, or even more than 99.99%, ensuring the safety and hygiene of water. UV lamps do not require the addition of chemical disinfectants. They only need to use ultraviolet rays to irradiate water bodies to achieve disinfection effects. They have no side effects or toxicity, and will not change the nutrients, minerals and taste of water. This makes ultraviolet disinfectors more environmentally friendly and avoids the risk of secondary pollution. They are often used for swimming pool disinfection, spa massage pool disinfection, tap water disinfection, etc.

[0003] In order to improve the sterilization effect of water bodies, the current UV lamp installs the ultraviolet lamp tube in the tube cavity of the shell, and then sets rubber rings on both sides of the shell. Then, the rubber rings are clamped by the plastic PG head and the shell thread connection to form a sealing effect. Then, the rubber water pipe is set on the water inlet and outlet of the shell, so that the water flows through the water flow cavity of the shell and is fully irradiated by the ultraviolet lamp to achieve an efficient sterilization effect.

[0004] However, ultraviolet rays are a high-energy radiation that has a strong sensitizing effect on plastics. When plastics are exposed to ultraviolet rays for a long time, ultraviolet rays will penetrate the surface of the plastic and enter its interior, and interact with the chemical bonds in the plastic molecules, causing reactions such as breakage, cross-linking and oxidation of the polymer molecules, thereby causing aging and failure of the plastic, which manifests as discoloration, brittleness, cracking, degradation and other phenomena; therefore, the rubber rings on both sides of the shell, the plastic PG head and the rubber water pipes connected to the outside of the shell will age due to long-term exposure to ultraviolet rays, reducing their service life and posing a risk of leakage.

[0040] Combine the following Figures 1 to 8 , describing an ultraviolet germicidal lamp according to an embodiment of the utility model.

[0043] The left and right parts of the light-transmitting airflow cavity 4 are respectively provided with light shielding members 41, which are used to block the light of the lamp tube 9 from irradiating the first sealing ring 1 and the second sealing ring 2;

[0044] The left port of the light-transmitting airflow cavity 4 is used to limit the power line of the lamp tube 9. The left part of the light-transmitting airflow cavity 4 is provided with a plurality of air holes 42, and the air holes 42 are used to allow external air to enter the light-transmitting airflow cavity 4;

When the lamp tube 9 is energized to generate ultraviolet rays of a certain wavelength (such as 240-280mm), the ultraviolet rays of this wavelength irradiate the air in the light-transmitting airflow chamber 4 and convert the oxygen in the air into ozone; the water outlet 32 ​​of the water flow chamber 3 is connected to the water outlet pipe, and the water outlet pipe can specifically be a venturi tube.

[0047] In addition, the light-transmitting airflow chamber 4 is nested in the water flow chamber 3, the left end of the water flow chamber 3 and the left part of the light-transmitting airflow chamber 4 cooperate to fix the first sealing ring 1 (such as a rubber ring), and the right end of the water flow chamber 3 and the right part of the light-transmitting airflow chamber 4 cooperate to fix the second sealing ring 2 (such as a rubber ring), so that the light-transmitting airflow chamber 4 and the water flow chamber 3 are sealed and fixed to each other, and the water flowing into the water flow chamber 3 from the water inlet 31 of the water flow chamber 3 can be fully irradiated by the ultraviolet light that passes through the light-transmitting airflow chamber 4, and after sterilization and disinfection, it flows out from the water outlet 32 ​​of the water flow chamber 3. More importantly, the water inlet 31 and the water outlet 32 ​​of the water flow chamber 3 are both provided with a shading structure 33, and the ultraviolet light irradiated on the water body will be blocked by the shading structure 33, and will not pass through the water inlet 31 and the water outlet 32 ​​to irradiate the connected rubber tube or plastic tube and other ultraviolet light sensitive components, effectively solving the problem of aging and reduced service life of ultraviolet light sensitive components such as rubber tubes or plastic tubes; and shading members 41 are respectively provided on the left and right parts of the light-transmitting airflow chamber 4, and the shading members 41 block the first sealing ring 1 and the second sealing ring 2, effectively preventing ultraviolet light from passing through the light-transmitting airflow chamber 4 to irradiate the first sealing ring 1 and the second sealing ring 2, and the water flow chamber 3 is made of metal material that will not conduct ultraviolet light, so the ultraviolet light is isolated from contacting the sealing ring, preventing the sealing ring from aging.
