The utility model provides a kind of air-blowing, comprises blow head, air bag and tail plug; Described blow head is connected with one end of described air bag, for being derived by the gas in air bag; The other end of described air bag is connected with described tail plug, and described tail plug is used for extraneous gas to import air bag; Described tail plug comprises tail plug main body and a through hole; Described through hole runs through described tail plug main body, and allows extraneous gas to pass through; One end of described tail plug main body is provided with a cover plate be connected with described tail plug subject activity, when described air bag is squeezed, described cover plate can cover described through hole, discharge from described tail plug to prevent gas in air bag, when extruding removed by described air bag, described cover plate opens from described through hole, enters described air bag to allow extraneous gas.The utility model has the advantage of, the gas in air bag can only be discharged from blow head, and can not discharge from tail plug, improves the service efficiency of air-blowing, meets the demand of user.
Description
Technical field
The utility model relates to electronic equipment enclosure technical field, particularly relates to a kind of air-blowing.
Background technology
Air-blowing is applied in cleaning of the precision instrument of a lot not easy-to-use water or cloth wiping as a kind of air blowing type burnisher, the such as camera lens of logarithmic code camera and the cleaning etc. of computer chip.Existing air-blowing comprises air bag and blow head, by extruding gasbag, the gas in air bag is produced by boasting from blow head in use and cleans.But existing air-blowing is when use is outwards blown, and gas also can blow out from the tail plug of afterbody, makes air-blowing can not meet the demand of user.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of air-blowing, and it can make air-blowing when giving vent to anger, and gas is only discharged from blow head, improves the service efficiency of air-blowing, meets the demand of user.
In order to solve the problem, the utility model provides a kind of air-blowing, comprises blow head, air bag and tail plug; Described blow head is connected with one end of described air bag, for being derived by the gas in air bag; The other end of described air bag is connected with described tail plug, and described tail plug is used for extraneous gas to import air bag; Described tail plug comprises tail plug main body and a through hole; Described through hole runs through described tail plug main body, and allows extraneous gas to pass through; One end of described tail plug main body is provided with a cover plate be connected with described tail plug subject activity, when described air bag is squeezed, described cover plate can cover described through hole, discharge from described tail plug to prevent gas in air bag, when extruding removed by described air bag, described cover plate opens from described through hole, enters described air bag to allow extraneous gas.
Further, described cover plate is connected by a connecting rod with described tail plug main body.
Further, described connecting rod adopts plastic material to make.
Further, described tail plug main body, described cover plate and described connecting rod are one-body molded.
Further, a described connecting rod part is fixedly connected with described tail plug main body, and the end of another part is connected with described cover plate, so that described cover plate is relative to the folding of described tail plug main body.
Further, described tail plug main body comprises one around the groove of described main body, and described groove is used for engaging with described air bag, to be fixed on described air bag by described tail plug.
The utility model has the advantage of, tail plug main body one end cover plate is set, when using air-blowing, the air bag of extruding air-blowing, the pressure in air bag changes, and makes cover plate cover through hole, gas in air bag can only be discharged from blow head, and can not discharge from tail plug, improve the service efficiency of air-blowing, meet the demand of user; When extruding removed by air bag, under the effect of external pressure, cover plate opens from described through hole, makes extraneous gas fill in out air bag from tail, until the pressure in air bag is consistent with external pressure.
Accompanying drawing explanation
Fig. 1 is the exploded perspective view of the utility model air-blowing;
Fig. 2 is the structural representation of the utility model tail plug;
Fig. 3 is the structural representation that the utility model cover plate opens.
Detailed description of the invention
The detailed description of the invention of air-blowing is provided to elaborate below in conjunction with accompanying drawing to the utility model.
See Fig. 1, the utility model air-blowing comprises blow head 2, air bag 3 and tail plug 1.Described blow head 2 is connected with one end of described air bag 3, for being derived by the gas in air bag 3; The other end of described air bag 3 is connected with described tail plug 1, and described tail plug 1 is for importing air bag 3 by extraneous gas.
See Fig. 2 and Fig. 3, described tail plug 1 comprises tail plug main body 10 and a through hole 11.Described through hole 11 runs through described tail plug main body 10, and allows extraneous gas to pass through.
One end of described tail plug main body 10 is provided with a cover plate 12 be flexibly connected with described tail plug main body 10.Described flexible connection refer to described cover plate 12 can with the connecting line of described tail plug main body 10 for axle rotates.When described air bag 3 is squeezed, air bag 3 internal pressure changes, and described cover plate 12 can cover described through hole 11 under pressure, discharge from described tail plug 1 to prevent gas in air bag 3, gas in air bag 3 is only discharged from blow head 2, improves the efficiency of air-blowing, meet consumers' demand.When extruding removed by described air bag 3, described cover plate 12 opens from described through hole 11, to allow extraneous gas to enter described air bag 3, until the pressure in air bag 3 is consistent with external pressure.
Further, described cover plate 12 is connected by a connecting rod 13 with described tail plug main body 10.Connecting rod 13 adopts plastic material to prepare.Preferably, a part for described connecting rod 13 is fixedly connected with described tail plug main body 10, and the end of another part is connected with described cover plate 12.Because described connecting rod 13 adopts plastic material to prepare, flexibility is larger, so, under the effect of external pressure, described cover plate 12 can with connecting rod 13 with tail plug main body 10 connecting line for axis of rotation, described cover plate 12 can in the surperficial folding of described tail plug main body 10, to cover described through hole 11 or not cover described through hole 11.Described cover plate 12 does not adopt any extra revolving member, only can realize the folding of cover plate 12 under external pressure effect, reduce the volume of tail plug 1, and cost-saving.
Further, described tail plug main body 10, described cover plate 12 and described connecting rod 13 are one-body molded, to save processing technology, cost-saving, shorten the production time of air-blowing, enhance productivity.
Further, described tail plug main body 10 comprises one around the groove 14 of described tail plug main body 10.Described groove 14 for engaging with described air bag 3, so that described tail plug 1 is fixed on described air bag 3.
The utility model air-blowing in use, extrude described air bag 3, gas is discharged from blow head 2, the pressure of air bag 3 inside changes, the cover plate 12 of tail plug be under pressure change impact and cover described through hole 11, thus stop the gas in air bag 3 to be discharged from described tail plug 1, improve the efficiency of air-blowing, meet consumers' demand.When air bag 3 extrudes releasing, by external pressure release action, the cover plate 12 of tail plug opens from described through hole 11, so that extraneous gas enters air bag 3 by through hole 11, is full of air bag 3, uses for next time.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
