Description
Technical field
The utility model belongs to water-treatment technology field, is related to water filtration and water treatment technology, is to be related to one specifically
Kind cold cathode ultraviolet sterilization device.
Background technology
Reverse osmosis water purifier is the main machine that water process is carried out using principle of reverse osmosis.Reverse osmosis membrane technology is that water is applied
Add certain pressure, make hydrone and the mineral matter element of ionic state passes through reverse osmosis membrane, and the overwhelming majority being dissolved in water
Inorganic salts (including heavy metal), organic matter and bacterium, virus etc. can not penetrate reverse osmosis membrane, so as to make the pure water penetrated
With the condensed water that can not penetrate is stringent separates.
But it is existing in the case of, water purifier usage time is long, and water tank and pipe content easily grow bacterium, and use is general
LED deep ultraviolet sterilizing units can reach bactericidal effect in the case where flow velocity is low, but if flow velocity reach 3L/MIN with
On, sterilizing rate will be substantially reduced, for the development of water purification industry, it is necessary to design a kind of cold cathode ultraviolet sterilization device.
Utility model content
The technical issues of the utility model solves is to provide a kind of cold cathode ultraviolet sterilization device, above-mentioned to solve
The problems in background technology.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is：
A kind of cold cathode ultraviolet sterilization device, including housing, quartz ampoule and cold cathode UV lamp, housing includes main body, on
End cap and bottom end cover, the upper and lower ends of main body are sealed and installed with upper end cover and bottom end cover respectively, and the side of upper end cover is equipped with water inlet
Pipe, water inlet pipe connect with housing cavity, the bottom of bottom end cover equipped with outlet pipe, enclosure interior equipped with quartz ampoule, quartz ampoule with it is upper
The interior lower seal connection of end cap, the quartz ampoule exterior tube are equipped with helical form guide vane with it, and quartz ampoule is internally provided with cold
Cathode ultraviolet lamp, upper end cover top are equipped with the extraction wire being connect with cold cathode UV lamp.
Further, the interior bottom of the bottom end cover is equipped with cushion collar, and cushion collar is equipped with matched slow with quartzy tube shape
Rush groove.
The utility model is simple in structure, volume smaller, using the quartz ampoule with helical form guide vane, can effectively extend water
Residence time inside housings extends and receives the irradiation time of cold cathode UV lamp, can effectively improve bactericidal effect, and existing
The LED deep ultraviolet sterilizing units of same volume are significantly improved compared to sterilizing rate in technology.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the internal structure schematic diagram of the utility model.
Fig. 3 is the structure diagram that the utility model removes main body and bottom end cover.
Fig. 4 is the schematic diagram that the utility model water is flowed along helical form guide vane.
In figure, main body 1, upper end cover 2, bottom end cover 3, quartz ampoule 4, cold cathode UV lamp 5, helical form guide vane 6, water inlet
Pipe 7, outlet pipe 8, extraction wire 9, cushion collar 10, buffer groove 11.
Specific embodiment
The utility model can be with the utility model will be further described, however, this practicality by the following examples
Novel range is not limited to following embodiments, can be made various changes in the range of the purport for not departing from the utility model.
Embodiment 1：Referring to Fig. 1 --- Fig. 4.
A kind of cold cathode ultraviolet sterilization device of the present embodiment, including housing, quartz ampoule 4 and cold cathode UV lamp 5, housing packet
Main body 1, upper end cover 2 and bottom end cover 3 are included, the upper and lower ends of main body 1 are sealed and installed with upper end cover 2 and bottom end cover 3, upper end cover respectively
2 side is equipped with water inlet pipe 7, and water inlet pipe 7 is connected with housing cavity, and the bottom of bottom end cover 3 is equipped with outlet pipe 8, and enclosure interior is set
There is quartz ampoule 4, quartz ampoule 4 is connect with the interior lower seal of upper end cover 2, is led with 4 exterior tube of quartz ampoule equipped with helical form
Blade 6 is flowed, quartz ampoule 4 is internally provided with cold cathode UV lamp 5, and 2 top of upper end cover is equipped with the extraction being connect with cold cathode UV lamp 5
Conducting wire 9.
Quartz ampoule collides and fragmentation when installation in order to prevent, and the interior bottom of the bottom end cover 3 is equipped with buffering
Set 10, cushion collar 10 are equipped with and the matched buffer groove 11 of 4 shape of quartz ampoule.
It is worth noting that the utility model, after extraction wire 9 is connected with power supply, cold cathode UV lamp 5, which is lighted, to be released
Ultraviolet wavelength, irradiation intensity 5000-9000UW/cm2 are put, water imports enclosure interior, and along helical form water conservancy diversion leaf by water inlet pipe 7
Piece, which flows downward, receives the illumination of cold cathode UV lamp 5, is finally discharged from outlet pipe 8, since helical form guide vane has spiral shell
The effect of water conservancy diversion is revolved, can effectively extend the residence time of water inside housings, when extension receives the irradiation of cold cathode UV lamp 5
Between, so as to improve bactericidal effect, it is not less than 99.99% using the utility model sterilizing unit, sterilizing rate under 2L/MIN flow velocitys.
