Fig. 1 is the structural representation for the water bottle that the utility model embodiment provides；Fig. 2 provides for the utility model embodiment
Back-flow preventer structural representation；Fig. 3 is the Longitudinal cross section schematic of back-flow preventer shown in Fig. 2.
The utility model provides a kind of back-flow preventer 100, including apparatus main body 600 and peripheral board 500, described device master
Body 600 is formed for the installation cavity on bottle 110 with peripheral board 500；
The first cavity 200 is provided with apparatus main body 600, the second cavity is provided with first cavity 200
300；The inlet opening 700 for water inlet is provided with the side wall of second cavity 300；
The baffle plate 800 for blocking current is provided with second cavity 300；The upper end of baffle plate 800 is arranged on
On the bottom plate 900 of first cavity 200；The inlet opening 700 is located at the lower end of the bottom plate 900.
As shown in Figure 2 and Figure 3, in the present embodiment, the installation cavity that apparatus main body 600 and peripheral board 500 are formed is arranged on bottle
On body 110, when the water in such bottle 110 needs to pour out, it is necessary to by back-flow preventer 100；Due to back-flow preventer
100 with bottle 110 be removably to be connected placement, when water is poured into bottle 110, removes back-flow preventer 100；So
Quickly water in bottle 110 can be filled；Water bottle can also be cup；The vessel of liquid are contained for people can use.
When drinking water, water in bottle 110 flows into the second cavity 300 from inlet opening 700, due to baffle plate 800 and the
The side wall of one cavity 200 forms diversion cavity, and after water flows into from inlet opening 700, the is flowed into by the opening of the lower end of baffle plate 800
In two cavitys 300, baffle plate 800 ensures that water is flowed out from the lower end of the second cavity 300, and the horizontal level of inlet opening 700 is close
Bottom plate 900；So remaining water can be prevented to be flowed into from inlet opening 700 in bottle 110；So prevent the water contacted with mouth
It is back in bottle 110, prevents the pollution of the water in bottle 110.
On above-described embodiment basis, further, the inner side of peripheral board 500 and/or outside are provided with for spiral shell
The screw thread connect.
In order to back-flow preventer 100 be connected with bottle 110 more firmly, the inner side of peripheral board 500 is provided with and can be screwed onto
Screw thread on bottle 110；This makes it possible to back-flow preventer 100 is firmly installed on bottle 110；Outside peripheral board 500
Side is with that can be threaded, for connecting bottle cap；The insulation to the water of bottle 110 is so achieved that, and prevents foreign matter from falling into
Onto back-flow preventer 100.
Be not in that water flows out from junction, in above-mentioned reality when installation for back-flow preventer 100 and bottle 110
Apply on example basis, further, the sealing strip 400 for sealing is provided with the installation cavity, and the sealing strip 400 is set
Put in described device main body 600.
For sealing strip 400 on apparatus main body 600, bottleneck and the apparatus main body 600 of bottle 110 have sealing strip 400；Such bottle
Gap between mouth and apparatus main body 600 is filled, and water can just flow out from from this gap.
On above-described embodiment basis, further, two sealing strips 400, two institutes are provided with the installation cavity
State sealing strip 400 be separately positioned in described device main body 600 and the peripheral board 500 on.
There is sealing strip 400 in bottle mouth inner and outer side, accordingly even when water can flow out at the sealing strip 400 on the inside of bottleneck,
Also can be sealed by the sealing strip 400 in outside；It more ensure that fastness and the sealing of back-flow preventer 100 and the installation of bottle 110
Property.
On above-described embodiment basis, further, the inlet opening 700 is arranged far from the peripheral board 500
In the side wall of second cavity 300.
Inlet opening 700 is strip hole, and such water can be flowed into more in the second cavity 300 from inlet opening 700, from water inlet
The water that hole 700 flows into is stopped that water flows along baffle plate 800 by baffle plate 800, between the bottom of the cavity 300 of baffle plate 800 and second
Gap is entered into the second cavity 300, after the second cavity 300, in the first cavity 200 of inflow, the mouth for finally entering people.
Inlet opening 700 can also be arranged in the side wall of the left and right sides of the second cavity 300, and such inlet opening 700 can be set
The somewhat dot put, the position of water outflow, the close side wall nearest from peripheral board 500, such water can preferably be flowed into the
In two cavitys 300, current are also more steady.
The utility model also provides a kind of water bottle, including back-flow preventer 100 and bottle 110 described above, described
The bottleneck for being connected with back-flow preventer 100 is provided with bottle 110.
As shown in figure 1, in the present embodiment, the water bottle of back-flow preventer 100 is installed on bottle 110, when drinking water,
It would not be again flowed into water bottle in clean water with the water of human contact, water is left behind in the second cavity 300, due to water
Less, it is necessary in the case of, it can be outwelled, for example be poured on one piece of toilet paper, it is very square so when work
Just.
On above-described embodiment basis, further, in addition to for covering the bottle cap of water bottle, the bottle cap is screwed onto
On the back-flow preventer 100.
There are the screw thread being connected with bottle 110 and the screw thread being connected with bottle cap on back-flow preventer 100, by peripheral board
It is threaded on 500, facilitates the connection with bottle 110 and bottle cap.
The utility model has the advantage that is with beneficial effect：By back-flow preventer 100, when people drink water,
Water is first flowed into the second cavity 300 from inlet opening 700, is flowed into the second cavity 300 in the first cavity 200, so as to people
It can drink；When stopping drinking water, remaining a small amount of water is stayed in the second cavity 300；Left when in the second cavity 300
When swill, it can be outwelled by what back-flow preventer 100 was left behind；It can so prevent in bottle 110
Water is contaminated, and be ensure that the clean of water in bottle 110, is also prevented from germ and enters bottle 110；Allow others to use in time, also can
The effective infection for preventing germ.
Finally it should be noted that：Various embodiments above is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, either to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
