Description
Technical field
The invention belongs to field of fuel cell technology, more particularly to a kind of feeding device of fuel liquid battery.
Background technique
Fuel cell is the device by converting the chemical energy in liquid fuel to electric energy, and reaction will be in certain temperature
It is carried out under the conditions of degree.In order to improve the fuel conversion efficiency of fuel cell and maintain stable operating temperature, system requirements fuel
Small flow is wanted in charging and charging is uniformly, avoids the occurrence of impulse form charging, and metering pump is general selection.Conventional fuel cell
There are two types of the feed process of liquid fuel: single pump charging and double pump charging.Wherein single pump charging refers to that liquid fuel charging only has
One pump, but this method need pump suction capacity, in terms of performance it is higher, corresponding power consumption also compared with
Greatly, be not suitable for the selection of the portable fuel battery of low-power.And double pump refers in internal system one buffer container of setting, wherein
System outer fuel is directly pumped into buffer container by one high-capacity pump, and in addition the fuel in buffer container is pumped by a low-capacity pump again
Battery, although which avoids uses powerful feed pump for a long time, also reduces to pump in suction capacity, blocking capability
Etc. performance requirement, buffer container plays the role of improving system stability, but due to using double pump, in power consumption
The output of portable fuel battery is influenced also larger.
Summary of the invention
The present invention is to solve the shortcomings of the prior art, provides a kind of feeding device of fuel cell liquid fuel.
The present invention is realized using following technical scheme:
A kind of device for fuel cell charging, the hollow closed fuel tank and charging of opening are equipped with including a lower end
Pump is equipped with fast joint chair in fuel tank opening, fast joint chair be inserted into fuel tank open interior and with opening airtight connection；
The fast joint chair is a block structure, one first groove is equipped in block structure upper surface middle part, in the first groove
Bottom is equipped with one second groove, is equipped with a through-hole in the second bottom portion of groove, in being equipped with a spool in the second groove, in the first groove
Inside be equipped with one middle part the spring support seat with through-hole, between spool and spring support seat be equipped with compression spring, spring support seat with
The inner wall airtight connection of first groove；It is mutually amplexiformed between spool and the bottom surface of the second groove；
One upper surface has the pedestal of third groove, is equipped with the entrance with feed pump in third bottom portion of groove or side wall surface
The through-hole being connected is equipped with a weight directly in the push rod of the bottom of third groove, fuel tank opening insertion in the bottom of third groove
In third groove, push rod stretches in through-hole below fast joint chair through-hole, and there are gap, push rod top and valves between push rod and through-hole
Core lower surface abuts against.
Sealing ring is equipped between the spool and the bottom surface of the second groove.
Pedestal sealing ring is equipped between the third groove and fuel tank opening.
It is equipped with air pressure double-beat drop valve in fuel tank, air pressure double-beat drop valve one end is connected with atmosphere, in the other end and fuel tank
Portion is connected.
The valve is check valve.
The spring support seat, spring, spool, sealing ring and fast joint chair are connected into ultrasonic welding with quick on-off
Valve body, and it is integrally welded with fuel tank opening, guarantee to seal at solder joint.
Compared with prior art, the invention has the following advantages that
1, fuel canister assembly fuel only connects place's one outlet fastly, and spring-loaded valve core when not using has blocked non-
The security risk that fuel leaks in use process.
2, using infusion apparatus principle, in fuel pump operation, fuel is easy to enter combustion from fuel tank under the effect of gravity
The problem of material pump, it is poor to solve existing low-power consumption pump suction capacity, can not effectively realize feeding work, so it is steady for fuel cell
Fixed work provides guarantee；
3, fuel canister assembly plays the role of buffering fuel-device, solves and additionally increases because fuel pump discharge is too small
The problem of one feed pump is as buffering fuel-device, reduces costs, improves reliability；
4, quick connection structure is simple, can fast implement the fast assembling-disassembling of fuel canister assembly.
Detailed description of the invention
Fuel cell feeding device structural schematic diagram shown in Fig. 1, the present invention；
In figure, air pressure double-beat drop valve (1), fuel tank (2), spring support seat (3), spring (4), spool (5), sealing ring (6),
Fast joint chair (7), pedestal (8), pedestal sealing ring (9), outlet tube (10), feed pump (11).
