Description

Technical Field

[0001] The present invention relates to the field of throttle valve technology, and more particularly to a self-cleaning and air supply adjustment device for throttle valve connector. Background Technology

[0002] Throttle body impurities are a common automotive malfunction. The main causes of throttle body carbon buildup are engine oil vapor, gasoline evaporation in the cylinders, and exhaust gas recirculation. When oil and gas mix with cold air entering through the throttle body, the oil and gas condense into a gel-like substance that adheres to the throttle body butterfly valve. As this gel accumulates, impurities eventually form near the butterfly valve, directly leading to adverse consequences such as difficulty starting the engine in cold weather, unstable idling, reduced power, increased emissions, and increased fuel consumption. Furthermore, the position of the throttle body connector prevents the adjustment of air supply to the internal combustion engine. If this oil, gas, and moisture can be cleaned promptly, reducing their ability to adsorb carbon deposits, the rate of carbon buildup in the throttle body will be significantly reduced. Additionally, to achieve optimal air supply within the internal combustion engine, multiple intake passages are interconnected.

[0003] In summary, to achieve self-cleaning and air supply adjustment within the throttle body connector, a simple and effective throttle body device needs to be designed. Therefore, we propose a self-cleaning and air supply adjustment device within the throttle body connector to solve the problems mentioned above. Summary of the Invention

The top of the air pipe 108 is provided with a fitting circular groove 109 for fixing the fitting valve body 201. The bottom surface inside the air pipe 108 is provided with an impurity sensing plate 104 for sensing impurities inside the air pipe 108.

[0037] The throttle valve assembly 2 includes a valve body 201 and a valve core 202. The valve core 202 is rotatably mounted inside the valve body 201, and the valve body 201 is fixedly mounted on the top of the valve seat 103. The valve core 202 includes a connecting rod 203, valve core blades 204, and an adjusting ring 205. The connecting rod 203 is rotatably mounted inside the valve body 201, and the valve core blades 204 and the adjusting ring 205 are fitted onto the connecting rod 203. The valve core blades 204 are rotatably mounted on the connecting rod 203, and the adjusting ring 205 is located between the valve core blades 204 to control the included angle of the valve core blades 204. The valve body 201 has a connecting boss 207 at the bottom, which is fixedly installed in the circular groove 109. The valve body 201 has a cylinder 210 on the side, and a connecting rod 203 is rotatably installed in the inner hole of the cylinder 206. The valve body 201 has a main air inlet 208 and a secondary air inlet 209, which are interconnected. The valve body 201 has an air groove 210, which is located inside the valve body 401. The air grooves 210 are cross-connected with the inner hole of the cylinder 206 as the center, and the air grooves 210 are interconnected with the secondary air inlet 209.

[0038] The cleaning component 3 is equipped with a cleaning cage 301, which is fixedly installed inside the valve seat 103. The cleaning cage 301 is equipped with a cleaning fan 302, which is driven by a motor 303. The motor 303 is fixedly installed on the ground inside the valve seat 103 and is controlled by an impurity sensing plate 104 fixedly installed on the ground inside the valve seat 103.

[0039] The cleaning cage 301 is provided with a large fixed circle 304 and a small fixed circle 305. The large fixed circle 304 and the small fixed circle 305 are fixed to a frustum 307 via a connecting arm 306. The frustum 307 is fixedly installed on a fixing ring 110. The cleaning fan 302 is provided with cleaning fan blades 308, which are evenly distributed on the outside of the cleaning fan 302.

The motor 303 drives the cleaning fan 302 to rotate inside the cleaning cage 301.

[0040] During use, the self-cleaning and air supply adjustment device inside the throttle body works by setting the amount of sediment through the impurity sensing plate 104. When the amount of sediment at the bottom exceeds the set value, the impurity sensing plate 104 transmits a rotation signal to the motor 303. Upon receiving the signal, the motor 303 drives the cleaning fan 302 to rotate and clean. When the impurity sensing plate 104 senses that the impurities have decreased to the set minimum value, it retracts the rotation signal. Gas is simultaneously supplied to the air pipe 108 through the main air intake 208 and the auxiliary air intake 209. This greatly increases the air supply. At the same time, according to the usage, the adjustment ring 205 on the valve core 202 sends an adjustment signal to the valve core blade 204, so that the valve core blade 204 rotates around the connecting rod 203 as the rotation center. When the two valve core blades 204 are 180° apart, the air supply is at its maximum and the air supply frequency decreases when rotating at low speed. However, after cooperating with the air groove 210, the air supply frequency is greatly increased. When the two valve core blades 204 are 90° apart, the air supply is at its minimum and the air supply frequency is at its highest when rotating. However, after cooperating with the air groove 210, the air supply is greatly increased.

[0041] The wiring diagram in this invention is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to the actual situation and the usage environment. Therefore, the control method and wiring layout of the impurity sensing board 104, throttle valve assembly 2, and cleaning assembly 3 will not be explained in detail.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
