Abstract
The utility model discloses a sprayer one-way valve which comprises a valve element and a pipe. The valve element covers the opening of the pipe and comprises a valve element body and a locating column, the valve element body is in the shape of a cake, an annular groove is formed in the lower end of the valve element body, the locating column is connected with the upper end of the valve element body, an annular magnet is further arranged on the valve element body, and the annular magnet is located at the right upper end of the annular groove and placed at the upper end of the valve element body. The sprayer one-way valve can effectively prevent backflow, reduce impact on the valve element when inner pressure and outer pressure of the pipe are changed, and prolong the service life of the overall valve element.
Description
Technical field
The utility model relates to sprayer field, specifically relates to a kind of sprayer one-way valve.
Background technique
Existing its structure of sprayer one-way valve generally all comprises a discoidal spool and a circular body, and spool is arranged on the mouth of pipe of body.In the time that body internal pressure is greater than ambient pressure, now the liquid in pipe backs down spool, and liquid is from managing interior outflow; In the time that extraneous pressure is greater than overpressure, now ambient pressure is pressed in spool on the mouth of pipe, thereby spool prevents in extraneous liquid intake channel.But when in use,, occasional exists liquid in pipe poor less with the outer liquid of pipe, now just easily causes in the slow intake channel of extraneous liquid, thereby causes adverse current phenomenon.
Model utility content
(1) technical problem that will solve
The deficiency existing for prior art, the utility model provides a kind of sprayer one-way valve that can effectively prevent adverse current.
(2) technological scheme
For achieving the above object, the utility model provides a kind of sprayer one-way valve, comprise spool and body, described cartridge cover is at the mouth of pipe of described body, and described spool comprises spool body and locating column, and described spool body is patty, the lower end of described spool body is provided with annular groove, described locating column is connected with the upper end of described spool body, on described spool body, is also provided with ring magnet, and described ring magnet is positioned at the positive upper end of described annular groove and is positioned at the upper end of described spool body.
Further, the upper end of described spool body is provided with ring magnet groove, and described ring magnet is arranged in described ring magnet groove.
Further, the material of described body is iron.
Further, described body is provided with annular secondary magnet, and described annular secondary magnet is arranged on the outside of described body.
Further, the material of described body is plastics, and the material of described spool body is rubber.(3) beneficial effect
The utility model sprayer one-way valve can effectively prevent adverse current, the impact to spool while reducing the change of pipe external and internal pressure, the working life of improving whole spool.
Brief description of the drawings
Fig. 1 is the cross-sectional view of spool in the utility model sprayer one-way valve;
Fig. 2 is the stereo directional structural representation of spool in the utility model sprayer one-way valve;
Fig. 3 is the overall structure schematic diagram of the utility model sprayer one-way valve.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
A kind of sprayer one-way valve structures of the present utility model as shown in Figure 1, Figure 2 and Figure 3, comprise spool and body 6, described cartridge cover is at the mouth of pipe of described body 6, described spool comprises spool body 1 and locating column 4, described spool body 1 is patty, the lower end of described spool body 1 is provided with annular groove 2, described locating column 4 is connected with the upper end of described spool body 1, on described spool body 1, be also provided with ring magnet 3, described ring magnet 3 is positioned at the positive upper end of described annular groove 2 and is positioned at the upper end of described spool body 1.
Concrete, the upper end of described spool body 1 is provided with ring magnet groove, and described ring magnet 3 is arranged in described ring magnet groove.
Wherein, the material of described body 6 is iron.Or described body 6 is provided with annular secondary magnet 5, and described annular secondary magnet 5 is arranged on the outside of described body 6.In the time that described body 6 is provided with annular secondary magnet 5, the material of described body 6 is plastics, and the material of described spool body 1 is rubber.
So in use, owing to there being the adsorption force of magnet between body 6 and spool, poor when little when pipe external and internal pressure, now spool is tightly adsorbed on the mouth of pipe, thereby prevents the generation of adverse current.In the process that this external sprayer uses, overpressure is greater than pipe pressure outside, thereby the liquid in pipe is pushed spool open, and liquid is from managing interior outflow, and the pressure in pipe reduces, thereby makes overpressure identical with pipe pressure outside.According to principle of inertia, the essentially identical situation of this pressure can keep the comparatively permanent time, and after this pressure increases suddenly in the other direction.In the time that opposite direction pressure increases suddenly, and spool is in the mouth of pipe, and now spool will fierce shock occur with the mouth of pipe, and this shock can reduce the working life of spool greatly.Magnet is set on spool, can makes spool be adsorbed on the mouth of pipe in advance, thereby can prevent this shock, and then improve the working life of whole spool.
The beneficial effects of the utility model: effectively prevent adverse current, the impact to spool while reducing the change of pipe external and internal pressure, the working life of improving whole spool.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
