Abstract

The utility model relates to an ultraviolet water sterilizer which adopts an ultraviolet ray tube. The utility model is characterized in that water pipes are concentrically suited outside of the ultraviolet ray tube at intervals. A ring-like interstice is provided between the inner side wall of the water pipe and the outer side wall of the ultraviolet ray tube. The ring-like interstice is a water channel. The utility model overcomes the traditional disadvantages that the ultraviolet ray can only be utilized to disinfect the surface of the object and air. Utilizing the light-admitting quality of water, the ultraviolet ray tube is directly arranged in the water channel. Thereby, the water flowing through the channel can be disinfected. The utility model has the advantages of ingenious and reasonable structure and arrangement, good sterilizing effect, and no 'secondary pollution'. The utility model can be widely applied in a plurality of situations. The utility model can be utilized as a running water sterilizer, coordinating with a filter. The utility model can be applied in the areas where running water pipe network can not reach, matching with a small sized water fetching electric pump, a filter, etc. The water can be directly fetched from underground or the earth surface. Thereby, the clean and hygienic standardized 'running water' can be obtained.

Description

Ultraviolet water sterilizer

Technical field:

The utility model relates to liquid steriliser.More particularly, especially a kind of water sterilizer.

Background technology:

In order to guarantee drinking-water quality, country has issued GB GB5749-85 " drinking water standard " and GB11730-1989 " water yield hygienic standard is drunk in life in the countryside " etc., and all tap water must conformance with standard.But in esse problem is:

1, the waterworks is through handling and reach the tap water that " standard " requires, through open-air seasoning, pipe network carry, user's water tank ... Zhongdao user uses.A series of middle-chain has caused the secondary pollution of water quality inevitably.For a long time, secondary pollution problem is not resolved all the time.

2, at present in China, the tap water pipe network of central water supply still is confined to cities and towns.In the place of rural area, remote districts and lack of water of quite a few, people's daily water consumption or taken from undergroundly by kill-job also has and directly takes from pond etc.Seriously there are problems such as water safety.

At the problems referred to above, also once occurring on the market can be for the water purifier of average family use.But its " purification " function of this water purifier only is embodied in the filtration.In fact, because strainer itself do not possess the sterilization function, thereby the problem of improving water quality is not really solved.Secondly, there is " secondary pollution " problem in the filter core of strainer equally after use after a while, and just because of this, such cleaner is not applied.

In the prior art, for the sterilization of water, ordinary method is that ozonization and chlorination are handled.But these two kinds of methods are because the problem that each side such as each comfortable sterilising effect, safe in utilization, use cost exist, and are unwell to be applied on " family type " water purifier.

Ultraviolet disinfection is a kind of very effectively sterilising method.But the application for the ultraviolet disinfection sterilizing function is confined to the body surface of big area, large space is sterilized always for a long time, and carries out sterilizing air.Up to now, water is carried out sterilization, yet there are no record about utilizing ultraviolet ray.

Summary of the invention:

Technical problem to be solved in the utility model provides a kind of ultraviolet water sterilizer.Become possibility so that disinfection by ultraviolet light is applied to " family type " water purifier, thereby improve water safety, thoroughly solve the secondary pollution problem.

The technical scheme that the utility model technical solution problem is adopted is:

The utility model adopts quartz burner.Its constructional feature is the outside at quartz burner, the sheathed water pipe of concentric spacing, and the annular spaces between water pipe inner side-wall and the quartz burner outer side wall is a water stream channel.

The utility model has overcome and traditional only has been used for understanding to being sterilized the surface and carrying out sterilizing air about ultraviolet ray.Utilize the light transmission of water, quartz burner is set directly in the water stream channel, thereby make the water that flows through in this passage processing that is sterilized.Its structure is provided with ingenious, reasonable.Because ultraviolet disinfection exists special advantages in many-side, comprising: 1, sterilization is extensive.Comprise that bacterium, fungi, germ, rickettsia, mould source body all can kill.It is reported that hepatitis virus and HIV (human immunodeficiency virus) are also all had killing effect preferably.2, pollution-free to harmless, the no burn into of sanitizer.3, non-residual toxicity.4, easy to use.The civil day light modulation is identical with using.Thereby, the utility model is applied to " family type " water purifier, can greatly improve sterilising effect, thoroughly solve secondary pollution.

The drawing explanation:

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model cross-sectional structure synoptic diagram.

Embodiment:

Referring to Fig. 1, present embodiment specifically adopts quartz burner 1, and in the outside of quartz burner 1, the sheathed water pipe 2 of concentric spacing is an annular spaces between water pipe 2 inner side-walls and quartz burner 1 outer side wall, and this annular spaces is water stream channel 3.

In concrete the enforcement, the import and export of water stream channel 3 should divide the two ends that are located at water pipe 2.Shown in the figure, current flow into water pipe from the import that is positioned at water pipe one end, flow out water pipe from the other end exit, and through the annular spaces that formed by water pipe 2 and quartz burner 1 time, the water while of flowing is sterilized by disinfection by ultraviolet light.

In order to guarantee safety in utilization, sealed structure should be adopted in the lamp holder position of ultraviolet lamp tube 1.Avoid the insecurity that to bring because of infiltration.

Shown in Figure 2, in the present embodiment, quartz burner 1 can adopt existing " H " type fluorescent tube.According to the size of the flow of water, be the long-pending of exposure intensity I and irradiation time t according to sterilization dose K, i.e. the principle of K=It is suitably selected the power of quartz burner.In order to guarantee sterilising effect, the series connection of the ultraviolet lamp tube more than two even two can be used.

The utility model can be used widely in various ways because cost is low, easy to use.Comprise: the complement filter device, as the disinfection of tap water device.Also can be applied in tap water pipe network area can't be obtained, directly fetch water, to obtain clean " tap water " that meet hygienic standard in the underground or face of land by being equipped with small-sized water intaking electric pump, strainer etc.

The utility model can be applicable to other all kinds of liquid that need sterilization equally.
