AI Technical Summary
The existing carburetor lacks a limit structure when the oil float moves with the oil volume, which causes the oil float to easily deviate and the valve seat of the oil inlet pipe cannot be sealed, resulting in continuous oil inlet and reducing the effectiveness of the carburetor.
A carburetor with an oil float limiting structure is designed. By installing a positioning plate and a limiting block on the float body, the movement of the float body is limited by using a sliding connection structure to prevent offset.
Effectively prevent the oil float from being offset, ensure that the needle valve on the float can seal the valve seat of the oil inlet pipe, avoid continuous oil inlet, and improve the use effect of the carburetor.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Embodiment 1:
[0033] In this embodiment, an oil storage chamber 2 is provided inside the carburetor outer shell 1, so oil can be transported into the oil storage chamber 2 through an oil inlet pipe 3. Figure 1 and Figure 7 As shown:
[0034] An oil inlet pipe 3 is installed on the left side of the carburetor outer shell 1, and the other end of the oil inlet pipe 3 is located in the oil storage chamber 2. A hydraulic rod 10 is also installed on the inner side of the oil storage chamber 2. A fixing pipe 12 is installed on the inner side of the carburetor outer shell 1.
[0035] The fixed pipe 12 is connected to one end of the air connecting pipe 13, and the other end of the air connecting pipe 13 is located outside the carburetor outer shell 1, the output end of the hydraulic rod 10 is connected to the push block 11, and the bottom of the hydraulic rod 10 is connected to the outer shell of the bottom oil detector 14, and the bottom oil detector 14 is fixed to the inner side of the oil storage chamber 2;
[0036] First, the carburetor outer shell 1 is installed at the corresponding position, and an oil inlet pipe 3 is arranged on the left side of the carburetor outer shell 1, and an oil storage chamber 2 is arranged on the inner side of the carburetor outer shell 1, so that oil can be transported to the oil storage chamber 2 through the oil inlet pipe 3, and a fixed pipe 12 is arranged on the inner side of the carburetor outer shell 1, and the fixed pipe 12 and the air connecting pipe 13 are connected to each other, and a hydraulic rod 10 is also installed on the inner side of the oil storage chamber 2, and the output end of the hydraulic rod 10 is connected to a pushing block 11, so that the fixed pipe 12 and the air connecting pipe 13 can be sealed by the pushing block 11, so that the incoming gas and oil are mixed, thereby ensuring the smooth progress of the oil supply work.
[0037] Embodiment 2:
[0038] In this embodiment, under the action of the limit block 7, the positioning plate 4 can be made to descend more smoothly, so that the float body 6 can move more smoothly, effectively preventing the skew phenomenon. Figure 2-Figure 3 and Figure 6 As shown:
[0039] A float body 6 is provided inside the oil storage chamber 2;
[0040] The upper surface of the float body 6 is connected to the positioning plate 4, and a sealing valve 5 is installed on the upper surface of the positioning plate 4, and a limiting block 7 is arranged on the left side of the positioning plate 4. The positioning plate 4 and the float body 6 are an integrated structure, and the positioning plate 4 and the sealing valve 5 are bonded and connected, and the size of the sealing valve 5 is consistent with the size of the outlet end of the oil inlet pipe 3. The limiting block 7 is connected to the inner wall of the oil storage chamber 2 through the connecting groove 8, and the connecting groove 8 is opened on the inner wall of the oil storage chamber 2. The limiting block 7 and the positioning plate 4 are an integrated structure, and the limiting block 7 and the connecting groove 8 are slidably connected;
[0041] When the amount of oil in the oil storage chamber 2 decreases, the float body 6 will drop with the decrease of the oil amount, so the float body 6 will drive the positioning plate 4 to drop together, and a limit block 7 is installed on the left side of the positioning plate 4, and the limit block 7 forms a sliding structure through the connecting groove 8 and the oil storage chamber 2, so when the positioning plate 4 drops, it will drive the limit block 7 to drop, so that the limit block 7 slides along the connecting groove 8, under the action of the limit block 7, the positioning plate 4 can be made to drop more smoothly, so that the float body 6 can move more smoothly, and the skew phenomenon can be effectively prevented.
[0042] Embodiment three:
[0043] In this embodiment, after the sealing valve 5 rises to a certain position, the oil inlet pipe 3 will be blocked, so that no oil will flow in. Figure 4-Figure 6 As shown:
[0044] A positioning rod 9 is passed through the interior of the positioning plate 4 and the float body 6, and the bottom end of the positioning rod 9 is fixed to the inner wall of the oil storage chamber 2;
[0045] When the oil level in the oil storage chamber 2 drops to a certain position, the bottom oil detector 14 will detect the oil level, and thus send the detected information to the external controller so as to refuel in time. When the oil inlet pipe 3 is refueled, the oil level in the oil storage chamber 2 increases, so that the float body 6 will rise with the increase of the oil level, and drive the positioning plate 4 and the limit block 7 to rise together. A sealing valve 5 is installed on the upper surface of the positioning plate 4, and the size of the sealing valve 5 is consistent with the size of the outlet end of the oil inlet pipe 3. Therefore, when the sealing valve 5 rises to a certain position, the oil inlet pipe 3 will be blocked, so that no more oil will be introduced. The interior of the positioning plate 4 and the float body 6 are penetrated by a positioning rod 9, and the bottom of the positioning rod 9 is fixed on the inner wall of the oil storage chamber 2. In this way, under the action of the positioning rod 9, the positioning plate 4 and the float body 6 can be made more stable when moving, thereby achieving the purpose of limiting the positioning plate 4 and the float body 6 again, and also improving the use effect of the carburetor. The above is the working process of the entire device. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
