Problems solved by technology
The existing carburetor has the defect of oil leakage. This is because the position of the atmospheric balance hole 3 of the existing carburetor is relatively low, or although the position is relatively high, the oil passage is not bent or blocked. When the engine is running, the engine bumps When it is violent and there is an inclined operation, gasoline splashes around in the carburetor oil cup 2, and it is easy to leak through the air balance hole 3, causing oil leakage, which affects the performance and safety of the product

Embodiment Construction
[0014] The present invention will be further described below in conjunction with the accompanying drawings.
[0015] see figure 2 and image 3 As can be seen from the figure, the anti-leakage structure of the carburetor of the present invention includes a carburetor body 1 and an oil cup 2, and the carburetor body 1 is provided with an atmospheric balance hole 3. The improvement of the present invention is that a baffle plate 4 is added in the carburetor body 1, the baffle plate 4 is arranged laterally, the baffle plate 4 is fixed on the carburetor body 1 by a rivet 5 (or screw), and the baffle plate 4 is provided with The second atmospheric balance hole 6 (see Figure 4 and Figure 5 ), the baffle plate 4 is located between the oil cup 2 and the atmospheric balance hole 3, and the inner cavity of the oil cup 2 communicates with the outside atmosphere through the second atmospheric balance hole 6 and the atmospheric balance hole 3 in turn. The baffle plate 4 has three fun...

The invention relates to an oil-leakage proofing structure of a carburetor, which comprises a carburetor body and an oil cup, wherein an atmosphere balance hole is arranged on the carburetor body. In the invention, the position of the atmosphere balance hole is raised up on the original base on the one hand; a baffle is arranged in the carburetor body on the other hand, and the baffle is providedwith a second atmosphere balance hole and is arranged between the oil cup and the atmosphere balance hole, and the oil cup passes through the second atmosphere balance hole and the atmosphere balancehole sequentially and communicates with atmosphere. The oil-leakage proofing structure can effectively stop the splashing of gasoline; moreover, even though passing though the balance hole on the baffle, the splashing gasoline can hardly reach the atmosphere balance hole on the carburetor body, thereby greatly reducing the possibility of oil leakage and improving the performance and safety of products.
Description
technical field [0001] The invention relates to the improvement of the carburetor, which can effectively prevent the carburetor from leaking oil through the atmospheric balance hole, thereby improving the performance and safety of the product. Background technique [0002] The carburetor is a mechanism that atomizes the mixture of air and fuel and supplies it to the cylinder for combustion. The carburetor includes a carburetor body 1 and an oil cup 2, and fuel is contained in the oil cup 2. See figure 1 , The carburetor body 1 is provided with an atmospheric balance hole 3, through which the air pressure in the oil cup 2 communicates with the atmospheric pressure to ensure that the fuel can be delivered normally. The existing carburetor has the defect of oil leakage. This is because the position of the atmospheric balance hole 3 of the existing carburetor is relatively low, or although the position is relatively high, the oil passage is not bent or blocked. When the engine...
