[0002] At present, the diaphragm flat-suction carburetors with oil bubbles generally adopt the ZAMA structure, and the diaphragm flat-suction chainsaw carburetors are mostly Huaboro carburetors. For carburetor manufacturers Generally speaking, the main structure of the two carburetors is very different, and the special processing machine cannot be used in common, resulting in an increase in processing equipment and causing a lot of inconvenience in production
Diaphragm flat-suction lawn trimmer carburetor body with oil bubble and diaphragm flat-suction chainsaw carburetor body cannot be used in common. The production of two carburetors requires mold opening and processing of the respective bodies, and the types of tooling that need to be processed and assembled There are many styles of accessories, and there are many styles of accessories, which makes the production cost higher

Abstract

The invention discloses a grass trimmer carburetor pump cover. The grass trimmer carburetor pump cover comprises a cover body, wherein an oil vacuole is arranged on the cover body, the oil vacuole andthe end face of the cover body are combined to form a pressing cavity, an oil return groove is formed in the side wall of the cover body, a first guide groove is formed in the pressing cavity, the first guide groove communicates with the oil return groove, a one-way flap assembly is arranged in the first guide groove so as to generate sealing for the first guide groove, a second guide groove usedfor communicating with a carburetor oil cavity is further formed in the cover body, one end of the second guide groove communicates with the pressing cavity, the other end of the second guide grooveextends towards the exterior of the cover body and forms a connection port, communicating with the carburetor oil cavity, in the cover body, and a check valve assembly used for preventing backflow isarranged on the connection port. The grass trimmer carburetor pump cover is reasonable in structure, does not need to additionally develop a mold for manufacturing a ZAMA body, and saves a large amount of cost.
