Abstract
The utility model relates to a pressure-boost type fuel tank cap, which comprises an air cylinder, a fuel tank cap arranged at the top part of the air cylinder and an inflating connecting rod arranged in the air cylinder and extending out of the fuel tank cap, wherein an inflating pressure plate is arranged at the top end of the inflating connecting rod, and a piston is arranged at the tail end of the inflating connecting rod; and an air outlet hole is arranged at the tail end of the air cylinder, and a rubber ring playing the function of a non-return valve and covering a breathing hole is sleeved at the tail end of the air cylinder. A cover plate and an air valve shifter plate in axial transmission connection with each other are arranged between the fuel tank cap and the inflating pressure plate in sequence, and a spring is arranged between the cover plate and the air valve shifter plate; a breathing hole suitable for being opened and closed by rotating the air valve shifter plate penetrates on the cover plate and the fuel tank cap at the outer edge of the air cylinder, that is, the breathing hole can be closed when the fuel tank is pressurized through the piston, thereby ensuring the pressurizing effect; and the breathing hole can be opened after the generator is started up, so as to avoid the phenomenon that the negative pressure is caused in the fuel tank since no air enters, and the generator can not be operated.
Description
Technical field
The utility model relates to a kind of supercharging type fuel tank cap.
Background technique
Existing generator starts difficulty in use for the first time or cold winter, because in the motor of this moment a spot of fuel oil only is housed, all is empty in the pipeline of conveying fuel oil, therefore generally all needs to start and just can start successfully many times, and is both time-consuming, again effort.
Chinese patent notification number CN201166017 discloses a kind of supercharging type fuel tank cap, comprises the fuel tank cap that is installed on the fuel tank, and described fuel tank cap is provided with the hand air pump to fuel-tank pressurization; This device is used for fuel-tank pressurization, makes pipeline transmit fuel oil at short notice, can start fast when motor is used for the first time, has saved time and strength.
Above-mentioned the deficiencies in the prior art part is: above-mentioned supercharging type fuel tank cap structure is complicated, adopts the one-way valve that is made of glass bead in its hand air pump, easily makes its damage when gasoline infiltrates in this one-way valve, causes its user cost higher and reliability is lower.
The model utility content
The technical problems to be solved in the utility model provides a kind of simple in structure, reliability supercharging type fuel tank cap preferably, is used to solve new generator or generator in the winter time and starts the problem of difficulty.
In order to solve the problems of the technologies described above, the utility model provides a kind of supercharging type fuel tank cap, comprising: inflator, be located at the fuel tank cap at inflator top and be located in the inflator and extend the connecting rod of inflating of fuel tank cap; Inflating the top of connecting rod is provided with and inflates platen, and the end of connecting rod of inflating is provided with piston; Be characterized in: the end of inflator is provided with air outlet hole, and the end of inflator is with the rubber ring that covers described vent, and this rubber ring plays the effect of one-way valve.
Further, fuel tank cap is provided with each other cover plate and the valve switch plate that axially transmission links to each other successively with inflating between the platen, be provided with spring between cover plate and the valve switch plate; On the cover plate of described inflator outer rim and fuel tank cap, run through to be provided with and be suitable for it being opened and closed vent, promptly, guarantee pressurized effect in fuel tank, during supercharging, making the vent closure by piston by the rotary valve switch plate.And after generator starts, vent is opened, and do not advance air and can cause negative pressure to prevent the fuel tank internal cause, cause generator not move.This is simple in structure, and is easy to operate, low production cost.
Further, for guaranteeing the supercharging using effect of this supercharging type fuel tank cap, be with on the described piston and be coated with lubricated seal ring with butter.
Further, for guaranteeing the supercharging using effect of this supercharging type fuel tank cap, the rubber parts that is sealed and matched with fuel tank cap is located at described inflator top.
Technique scheme of the present utility model has the following advantages compared to existing technology: (1) supercharging type fuel tank cap of the present utility model, give the oil circuit supercharging by the supercharging type fuel tank cap, make the interior fuel oil of fuel tank arrive Carburetor by oil pipe rapidly, thereby the startup of acceleration generator, so new generator or the difficult problem of the startup of generator have in the winter time been solved.(2) end of inflator is provided with air outlet hole, and the end of inflator is with the rubber ring that covers described vent, and this rubber ring plays the effect of one-way valve, and is simple in structure, with low cost, even if infiltration gasoline does not influence the sealing between described vent and the rubber ring yet, so reliability is better.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the plan view of supercharging type fuel tank cap of the present utility model.
Embodiment
See Fig. 1, the supercharging type fuel tank cap of present embodiment comprises: inflator 2, be located at the fuel tank cap 1 at inflator 2 tops and be located in the inflator 2 and extend fuel tank cap 1 inflate connecting rod 3; Inflating the top of connecting rod 3 is provided with and inflates platen 4, and the end of connecting rod 3 of inflating is provided with piston 10; Be characterized in: the end of inflator 2 is provided with air outlet hole 2-1, and the end of inflator 2 is with the rubber ring 2-2 that covers described vent 2-1.
Fuel tank cap 1 is provided with each other cover plate 8 and the valve switch plate 7 that axially transmission links to each other successively with inflating between the platen 4, be provided with spring 6 between cover plate 8 and the valve switch plate 7; On the cover plate 8 of described inflator 2 outer rims and fuel tank cap 1, run through to be provided with and be suitable for it being opened and closed vent 11 by rotary valve switch plate 7; The closure that is vent 11 when inflating connecting rod 3 work, open when connecting rod 3 quits work inflating, do not advance air and can cause negative pressure, cause generator not move to prevent the fuel tank internal cause.
Be with on the described piston 10 and be coated with lubricated seal ring 5 with butter.
