Abstract
The utility model discloses a swimming life -buoy aerating device, including cylinder body (1) and piston (2), install in cylinder body (1) piston (2), and piston (2) top middle part is provided with handle (21), and piston (2) face side is provided with air cock window (22), and air cock window (22) outside is provided with sealed rubber ring (23), still is provided with on piston (2) face to be used for carminative one -way air outlet valve (24), the swimming life -buoy aerating device process of aerifing need not to calm the anger repeatedly, inflater inflation kit labour saving and time saving current relatively, and need not power consumptively, it uses place unrestricted.
Description
Technical field
This utility model relates to swimming life-buoy inflatable tool, is specifically related to a kind of swimming life-buoy aerating device.
Background technology
Existing swimming life-buoy in use, is first by inflation, thing hard when inflation is special charges, directly blows with mouth, though need not by instrument, but its inflation to include steam more, and consumption strength consuming time especially; Adopt inflator to inflate it is generally required to three to five minutes, equally also compare effort; And adopt electrodynamic type aerating device, although speed soon and not effort, but its device uses and must be powered on, it is more difficult to uses at Swimming pool.
Utility model content
Prior art problem to be solved in the utility model is: existing swimming life-buoy adopts the inflation of non-electrical dynamic formula instrument to compare and takes time and effort, and adopts the inflation of electrodynamic type instrument need power consumption and be subject to place restriction.
For solving above-mentioned technical problem of the prior art, this utility model provides following technical scheme: a kind of swimming life-buoy aerating device, and including cylinder body 1 and piston 2, piston 2 is arranged in cylinder body 1;
It is characterized in that: piston 2 upper center is provided with handle 21, and piston 2 plate face side is provided with valve window 22, and valve window 22 arranged outside has O-ring seal 23, and piston 2 plate face is additionally provided with the unidirectional air outlet valve 24 for aerofluxus.
As further optimization, described piston 2 plate face periphery is provided with draw-in groove 25, and the medial surface of draw-in groove 25 periphery sides and the lateral surface of cylinder body 1 are provided with helicitic texture 26.
Operation principle: swimming life-buoy aerating device described in the utility model, during use, launch to be placed in piston 2 bottom surface by swimming life-buoy, by the valve window 22 of swimming life-buoy valve traverse piston 2, and be pressed in cylinder body with piston 2, its swimming life-buoy is made to be positioned at cylinder body 1, again the gas in cylinder body 1 is discharged by unidirectional air outlet valve 24, then piston 2 will mention certain position again, make cylinder body internal gas pressure and swimming life-buoy air pressure inside be negative pressure, enter in swimming life-buoy it is thus possible to make extraneous gas pass through swimming life-buoy valve, it is achieved the inflation to swimming life-buoy.
Beneficial effect: swimming life-buoy aerating device described in the utility model, by making swimming life-buoy air pressure inside be, negative pressure realizes sucking in swimming life-buoy by extraneous gas, and this gas replenishment process is without repeatedly calming the anger, and relatively existing inflator inflatable tool is time saving and energy saving, and without power consumption, field of employment is unrestricted.
Accompanying drawing explanation
Fig. 1 is this utility model scheme one plan structure figure;
Fig. 2 is this utility model scheme one lateral cross section structure chart;
Fig. 3 is this utility model scheme two lateral cross section structure chart;
In figure: 1 be cylinder body, 2 be piston, 21 be handle, 22 be valve window, 23 be O-ring seal, 24 be unidirectional air outlet valve, 25 be draw-in groove, 26 for helicitic texture.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Scheme one (as depicted in figs. 1 and 2): a kind of swimming life-buoy aerating device, including cylinder body 1 and piston 2, piston 2 is arranged in cylinder body 1; Piston 2 upper center is provided with handle 21, and piston 2 plate face side is provided with valve window 22, and valve window 22 arranged outside has O-ring seal 23, and piston 2 plate face is additionally provided with the unidirectional air outlet valve 24 for aerofluxus.
Scheme two (as shown in Figure 3): be different in that with scheme one: described piston 2 plate face periphery is provided with draw-in groove 25, and the medial surface of draw-in groove 25 periphery sides and the lateral surface of cylinder body 1 are provided with helicitic texture 26.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; it is not limited to this utility model; although this utility model being described in detail with reference to previous embodiment; for a person skilled in the art; technical scheme described in foregoing embodiments still can be modified by it; or wherein portion of techniques feature is carried out equivalent replacement; all within spirit of the present utility model and principle; any amendment of being made, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
