Abstract
The utility model relates to a mini-inflator which comprises an air cylinder handle, a piston, an air cylinder and an air tap head; the air cylinder handle is connected with the piston by a connecting pipe; the piston is arranged inside the air cylinder, and a gap is formed between the cylinder wall of the air cylinder and the piston; a downward leather bowl is arranged between the lower side end of piston and the cylinder wall of the air cylinder; the lower end of the air cylinder is communicated with the air tap head by an air outlet; the air tap head is provided with a one way valve; the upper side end of the connecting pipe is provided with an air inlet; a pylome is arranged on the piston; the connecting pipe is communicated with the pylome; an upward leather bowl is arranged between the upper side end of the piston and the cylinder wall of the air cylinder; the upper end of the air cylinder is provided with a one way valve; an air pipe is arranged on the outer sidewall of the air cylinder; the air pipe is communicated with the air cylinder by an air inlet which is positioned on the upper part of the one way valve; and the air pipe is communicated with the air tap head by the air outlet. The mini-inflator adopts a double air cylinder space, can realize the inflating effect by pulling or pressing the air cylinder handle, which greatly improves the working efficiency.
Description
Technical field
The utility model relates to the pump technical field, relates in particular to mini inflating pump.
Background technique
Present pump principle generally is, when using pump, its valve head is received on the valve of bicycle tyre, valve act as and only allows air to enter tire from pump, do not allow air to blow back into pump from tire, be formed with the space between the piston of pump and the barrel, and have on the piston to recessed rubber cup, when upwards spurring inflator handle, when drawing piston on promptly, the volume of air of piston below increases, pressure reduces, and the air of piston top just is extruded into the below around rubber cup, when pressing down piston, piston below volume of air is dwindled, pressure increases, and makes rubber cup be tight against barrel and does not allow air drain to the piston top, continues to pressing down piston, when atmospheric pressure was enough to back down the valve inside of tire, pressurized air just entered tire. and the outer air of tube enters the top of piston from the space of tube upper end simultaneously.Promptly only when pressing down, just tire is inflated, it is running back and forth up and down, can only reach the effect of inflating of half, and is uneconomical, also waste of manpower.
Summary of the invention
The utility model provides a kind of preferable mini inflating pump of effect of inflating at deficiency of the prior art.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Mini inflating pump, comprise inflator handle, piston, the gentle mouth of inflator, described inflator handle connects piston by connecting leg, and described piston places in the inflator, and is formed with the slit with the barrel of inflator, and be provided with to down cup between the barrel of piston underside end and inflator, described inflator lower end is communicated with the valve head by the air outlet, is provided with one-way valve in the described valve head, and described connecting leg upside is provided with suction port, described piston is provided with through hole, and described connecting leg is communicated with through hole; Be provided with upwards leather cup between the barrel of described piston upside and inflator, described inflator upper end is provided with one-way valve; Also be provided with tracheae on the outer side wall of described inflator, described tracheae is communicated with inflator by suction port, and described suction port is positioned at the one-way valve top, and described tracheae is communicated with the valve head by the air outlet.
By the technical solution of the utility model, adopt two inflator spaces, regardless of being the pulling inflator handle or pushing inflator handle and can both realize inflating effect, increase work efficiency greatly.
Figure of description
Fig. 1 is the utility model mini inflating pump internal structure schematic representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in Figure 1, mini inflating pump, comprise inflator handle 1, piston 12, inflator 6 gentle mouths 9, described inflator handle 1 connects piston 12 by connecting leg 15, described piston 12 places in the inflator 6, and be formed with the slit with the barrel of inflator 6, and be provided with to down cup 5 between the barrel of piston 12 lower sides and inflator 6, described inflator 6 lower ends are communicated with valve head 9 by air outlet A7, be provided with one-way valve A8 in the described valve head 9, described connecting leg 15 upsides are provided with suction port A2, and described piston 12 is provided with through hole 11, and described connecting leg 15 is communicated with through hole 11; Be provided with upwards leather cup 4 between the barrel of described piston 12 upsides and inflator 6, described inflator 6 upper ends are provided with one-way valve B3; Also be provided with tracheae 13 on the outer side wall of described inflator 6, described tracheae 13 is communicated with inflator 6 by suction port B14, and described suction port B14 is positioned at one-way valve B3 top, and described tracheae 13 is communicated with valve head 9 by air outlet B10.And piston 12 just in time is divided into upper and lower space with inflator 6.
During use, when promoting inflator handle 1, work to down cup 5, gas enters the inflation object through air outlet A7, one-way valve A8, valve head 9 in 6 times spaces of inflator in inflator 6 lower ends.And this moment, the tube outer air also enters in the connecting leg 15 from suction port A2, thereby enters space on the inflator 6 by through hole 11; And pulling is during inflator handle 1, and upwards leather cup 4 works, on the inflator 6 in the space gas enter the inflation object through one-way valve B3, suction port B14, the air outlet B10 of tracheae 13 lower ends, valve head 9.And this moment, the tube outer air also enters in the connecting leg 15 from suction port A2, thereby enters 6 times spaces of inflator by through hole 11.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
