Description
Technical field
The invention belongs to field of fuel cell technology, more particularly to a kind of feed arrangement of fuel liquid battery.
Background technology
Fuel cell is the device by the way that the chemical energy in liquid fuel to be converted into electric energy, and its reaction will be in certain temperature
Under the conditions of carry out.In order to improve the fuel conversion efficiency of fuel cell and maintain the operating temperature of stabilization, system requirements fuel
Low discharge is wanted in charging and charging is uniform, it is to avoid impulse form charging occur, and measuring pump is general selection.Traditional fuel
The feed process of battery liquid fuel has two kinds：Single pump charging and double pump charging.Wherein single pump charging refers to that liquid fuel enters
Material only one of which pump, but the pump that this method needs is higher in the performance of the aspects such as suction capacity, blocking capability, accordingly
Power consumption it is also larger, be not suitable for the selection of the portable fuel battery of low-power.And double pump refers to set one in internal system
Buffer container, wherein system outer fuel is directly pumped into buffer container by a high-capacity pump, a low-capacity pump again will buffering in addition
Fuel in container pumps into battery, and although the setting avoids and use powerful feed pump for a long time, also reduces to pump
In the performance requirement of the aspects such as suction capacity, blocking capability, buffer container serves the effect for improving the stability of a system, but
It is that, due to using double pump, the output influence on portable fuel battery in power consumption is also larger.
The content of the invention
A kind of deficiency that the present invention exists for solution prior art, there is provided feed arrangement of fuel cell liquid fuel.This
Invention is realized using following technical scheme：
A kind of device for fuel cell charging, an including lower end is provided with hollow closed fuel tank and the charging of opening
Pump, is provided with fast joint chair at fuel tank opening, fast joint chair insertion fuel tank open interior and with opening airtight connection；
The fast joint chair is a block structure, one first groove is provided with block structure upper surface middle part, in the first groove-bottom
Portion is provided with one second groove, and a through hole is provided with the second bottom portion of groove, recessed in first in a valve element is provided with the second groove
A spring support seat of the middle part with through hole is provided with groove, compression spring, spring supporting are provided between valve element and spring support seat
Seat and the internal face airtight connection of the first groove；Mutually amplexiformed between the bottom surface of valve element and the second groove；
Base of one upper surface with the 3rd groove, the entrance phase with feed pump is provided with the 3rd bottom portion of groove or side wall
The through hole of connection, is provided with a weight straight in the push rod of the bottom of the 3rd groove, the insertion of fuel tank opening in the bottom of the 3rd groove
In 3rd groove, push rod is stretched in through hole from fast joint chair through hole lower section, and gap, push rod top are left between push rod and through hole
Abutted against with valve element lower surface.
Sealing ring is provided between the bottom surface of the valve element and the second groove.
Base sealing ring is provided between the 3rd groove and fuel tank opening.
Air pressure double-beat drop valve is provided with fuel tank, air pressure double-beat drop valve one end is connected with air, inside the other end and fuel tank
It is connected.
The valve is check valve.
The spring support seat, spring, valve element, sealing ring and fast joint chair ultra-sonic welded are connected into quick on-off
Valve body, and by its with fuel tank opening at it is integrally welded, it is ensured that sealed at solder joint.
Compared with prior art, the present invention has advantages below：
1st, fuel canister assembly fuel only connects place's one outlet soon, spring-loaded valve core when not using, and has blocked non-
The security risk of fuel leakage during use.
2nd, using transfusion device principle, in fuel pump operation, fuel is easy to enter from fuel tank under gravity and fires
Material pump, solves existing low-power consumption pump suction capacity poor, it is impossible to effectively realizes the problem of feeding work, and then is fuel electricity
Pond steady operation is provided and ensured；
3rd, fuel canister assembly serves the effect of buffering fuel-device, and solve additionally increases because fuel pump discharge is too small
One feed pump reduces cost as the problem of buffering fuel-device, improves reliability；
4th, quick connection structure is simple, can quickly realize the fast assembling-disassembling of fuel canister assembly.
