Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1-2, a fully sealed carburetor includes a carburetor housing 1 and a seal cover 2, wherein the seal cover 2 is hermetically connected to the upper end of the carburetor housing 1, and a closed space for arranging a carburetor throttle shaft 3 and a carburetor choke shaft 4 is formed between the seal cover 2 and the carburetor housing 1; generally, the carburetor shell 1 and the seal cover 2 can be in an integrated structure, a certain airtight space can be formed after the carburetor shell 1 and the seal cover 2 are in butt joint by forming a concave structure on the carburetor shell 1 and a concave structure on the seal cover 2, and the carburetor shell 1 and the seal cover 2 are connected through bolts;

in this structural design, through setting up sealed cowling 2 in the upper end sealing connection of carburetor casing 1, the completion that can be fine is to the airtight of carburetor throttle shaft 3 and choke shaft 4 exposed part, can be fine block dust, silt and water to the corruption of throttle shaft hole, choke shaft hole etc. avoid the problem such as axle jamming, and then improve the product performance and the life of carburetor, can adapt to more abominable operational environment.
