AI Technical Summary
Existing carburetors cannot adjust the oil supply according to temperature differences, resulting in the oil supply in high and low temperature environments that cannot match, affecting the normal operation of the engine.
A new carburetor was designed, including the carburetor body, adjustment chamber and adjustment bolts. The engine oil enters the adjustment chamber through the oil inlet pipe, the side oil passage and the bottom oil passage, and then enters the middle cavity through the oil outlet hole. By rotating the adjustment bolt to adjust its rotation length, the flow rate of oil in the adjustment chamber is controlled, thereby adjusting the amount of oil supply according to different temperature environments.
The oil supply is adjusted according to different temperature environments, so that gasoline engine oil can better adapt to high and low temperature environments and ensure the normal operation of the engine under different temperature conditions.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carburetors, in particular to a new type of carburetor. Background Technique
[0002] The engine oil of the existing carburetor is sucked in from the upper oil pipe, and through the conversion of the internal channels of the carburetor, the engine oil is sucked into the engine cylinder below the throttle valve of the carburetor, passing through a check valve diaphragm, a filter screen, and a metering orifice in the middle.
[0003] The check valve diaphragm plays a role of a one-way oil circuit in the oil circuit, effectively offsetting the oil pressure in the oil tank and avoiding the situation of oil overflow in any case.
[0004] The filter screen in front of the metering orifice can filter impurities in the engine oil well, solve the problem of the metering orifice being blocked by impurities, and the metering orifice can control the oil supply.
[0005] However, the fluidity of the engine oil has a great relationship with the temperature. In summer with high temperature, the engine oil flows fast, while in winter with low temperature, the engine oil flows slowly. The metering orifice cannot adjust the flow rate according to the temperature difference, which will cause the oil supply of the metering orifice with a high-temperature ratio not to meet the working requirements in a low-temperature environment, and vice versa.
[0006] Therefore, we propose a new type of carburetor to facilitate the solution of the problems mentioned above. Content of the Utility Model
[0007] The purpose of the utility model is to provide a new type of carburetor to solve the problems mentioned in the above background technique.
[0008] To achieve the above purpose, the utility model provides the following technical solution: A new type of carburetor, comprising: a carburetor body, the upper end of the carburetor body is connected to an oil inlet pipe, and a middle cavity is opened in the middle of the carburetor body;
[0009] The side of the bottom of the carburetor body is threadedly installed with an adjusting bolt. An adjusting cavity is arranged between the middle cavity and the bottom oil circuit of the carburetor body. The head of the adjusting bolt is inserted into the adjusting cavity, and the adjusting cavity is communicated with the oil inlet pipe through an oil circuit;
[0010] An oil outlet hole is opened at the bottom of the middle cavity of the carburetor body, and the oil outlet hole communicates the adjusting cavity and the middle cavity.
[0011] Preferably, a side oil circuit and a bottom oil circuit are opened in the carburetor body. The side oil circuit and the bottom oil circuit are communicated, and the upper end of the side oil circuit is communicated with the oil inlet pipe.
[0012] Preferably, the side oil circuit includes a check valve cavity, and a check valve, a metering orifice and a filter screen are arranged in the check valve cavity.
[0013] Preferably, the adjusting bolt comprises a bolt body, on which a spring is sleeved. One end of the spring abuts against the surface of the carburetor body, and the other end abuts against the nut of the bolt body.
[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0015] The engine oil sequentially enters the adjusting cavity through the oil inlet pipe, the side oil passage and the bottom oil passage, and then enters the middle cavity from the adjusting cavity through the oil outlet hole. By rotating the adjusting bolt to adjust its screwing-in length, the oil flow in the adjusting cavity is controlled, and the amount of engine oil supply can be adjusted according to different temperature environments, so that the gasoline engine oil can better adapt to high-temperature and low-temperature environments.

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to Figures 1-3 , the present utility model provides a technical solution: a new type of carburetor, comprising: a carburetor body 1, an oil inlet pipe 4 is connected to the upper end of the carburetor body 1, a middle cavity 3 is opened in the middle of the carburetor body 1, and a door piece 2 is arranged in the middle cavity 3.
[0022] A side oil passage 12 and a bottom oil passage 13 are opened in the carburetor body 1, the side oil passage 12 and the bottom oil passage 13 are communicated, and the upper end of the side oil passage 12 is communicated with the oil inlet pipe 4;
[0023] The side oil passage 12 includes a check valve cavity 11, and a check valve and an orifice are arranged in the check valve cavity 11.
[0024] An adjusting bolt 5 is installed on the side of the bottom of the carburetor body 1 by threading. An adjusting chamber 14 is provided between the middle chamber 3 and the bottom oil passage 13 of the carburetor body 1. The end of the adjusting bolt 5 is inserted into the adjusting chamber 14 to control the flow rate of the adjusting chamber 14.
[0025] An oil outlet hole 6 is opened at the bottom of the middle chamber 3 of the carburetor body 1. The oil outlet hole 6 communicates the adjusting chamber 14 and the middle chamber 3.
