[0002] With the continuous development of the automotive industry and increasing environmental protection requirements, combustion efficiency and emission control in automotive engines have become crucial for improving vehicle performance and reducing environmental pollution. During the combustion process, traditional automotive engines often experience incomplete combustion due to uneven mixing of fuel and air, resulting in significant exhaust emissions, particularly harmful substances such as hydrocarbons, nitrogen oxides, and carbon monoxide. Furthermore, carbon deposits within the combustion chamber and intake manifold are a common cause of reduced engine performance and excessive emissions.

[0003] To address these issues, a growing number of technical solutions are focusing on improving engine performance and emissions by optimizing the air-fuel mixture, enhancing combustion efficiency, and reducing carbon deposits. Negative ion technology has attracted attention for its ability to effectively improve gas flow, promote uniform mixing of gas and fuel, and enhance combustion efficiency.

[0004] Existing negative ion generator technology lacks effective solutions for use in automobile cabins. Although negative ions can be generated, there are common problems such as insufficient negative ion release, short duration, and insufficient mixing with cabin air, making it difficult to achieve a significant improvement in engine performance.

[0019] 2. By providing a stirring shaft and stirring blades, the incoming air drives the impeller and stirring shaft, allowing the negative ion generator to continuously stir the negative ion-releasing filler in the storage tank, ensuring that the activity of the negative ion-releasing filler does not decrease with time or frequency of use. The design of the stirring blades allows the negative ion-releasing filler to be more evenly distributed in the storage tank, thereby increasing the amount of negative ions released and improving the negative ion release effect.

[0020] 3. Through a rationally designed power transmission system, air flow effectively drives the impeller during vehicle movement, thereby driving the agitator shaft and paddles. The paddles agitate the negative ion-releasing filler in the storage tank, releasing the negative ions more evenly and allowing them to mix thoroughly with the cabin air. The negative ions efficiently blend with the cabin air and enter the engine with the airflow. This not only improves air quality but also effectively enhances the mixing efficiency of fuel and air, promoting greater combustion efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] See also Figure 1-6 A negative ion generator for a car engine compartment includes a storage barrel 1 and an inner assembly cover 2 and an outer assembly cover 3 assembled at the barrel mouth 11 of the storage barrel 1. The storage barrel 1 is filled with negative ion releasing filler, and the space between the outer assembly cover 3 and the inner assembly cover 2 is set as a power chamber 12.

[0030] It also includes a rotating seat 4, a stirring shaft 51 and a stirring blade 52 fixed to the stirring shaft 51. The rotating seat 4 is rotatably installed at the axis center of the inner assembly cover 2. The top end of the stirring shaft 51 is nested and plugged into the rotating seat 4, and the bottom end of the stirring shaft 51 is rotatably installed at the bottom of the storage barrel 1. The stirring blade 52 is arranged in the storage barrel 1.

[0031] It also includes a drive assembly assembled in the power chamber 12, the drive assembly includes a drive shaft 61 and a wind impeller 62 fixedly mounted on the drive shaft 61, the top end of the drive shaft 61 is rotatably mounted at the axis of the outer assembly cover 3, and the bottom end of the drive shaft 61 is nested and plugged with the rotating seat 4.

[0032] When the car is moving, the air entering the cabin can blow the impeller 62 to operate, thereby driving the drive shaft 61 to operate. The drive shaft 61 transmits power to the stirring shaft 51 through the rotating seat 4, thereby driving the stirring shaft 51 and the stirring blades 52 thereon to operate. The stirring blades 52 can stir the negative ion releasing filler filled in the storage barrel 1 to increase the amount of negative ions released. After the negative ions are released, they mix with the air entering the cabin and enter the engine together, thereby improving the engine's working efficiency.

[0033] The negative ion releasing filler is one or more of minerals, ceramic materials, and special metal oxides. For example, tourmaline and negative ion powder (such as titanium dioxide, aluminum oxide, etc.) can generate and release negative ions.

[0034] When negative ions enter the engine, they help mix fuel and air more evenly, improving fuel atomization and boosting combustion efficiency while reducing incomplete combustion. They also help reduce carbon deposits in the combustion chamber and intake duct, which improves combustion efficiency and reduces engine wear. By altering the chemical reaction kinetics during combustion, negative ions promote complete combustion and improve efficiency. By increasing combustion efficiency and reducing incomplete combustion, negative ions can also reduce harmful emissions.

[0035] On the basis of the above technical solution, in order to ensure that the negative ions released by the negative ion releasing filler can diffuse to the outside of the storage barrel 1 and enter the engine together with the air entering the car cabin, the following technical solution is provided.

[0036] Diffusion holes 13 are formed on the side walls and the bottom wall of the storage barrel 1 , inner through holes 21 are evenly formed on the inner assembly cover 2 , and outer through holes 31 are evenly formed on the outer assembly cover 3 .

[0037] The setting of the outer through hole 31 and the inner through hole 21 can ensure that the air entering the car cabin can be stably transported to the storage barrel 1 along the axial direction of the outer assembly cover 3 and the inner assembly cover 2, and blow the impeller 62 in the power chamber 12 to operate, so as to achieve stable operation of the drive shaft 61 and the stirring shaft 51. When the air enters the storage barrel 1, it can carry the released negative ions to diffuse outward along the diffusion through hole 13 and enter the engine together with the air.

The combination of the external thread A14 and the internal thread A32 can ensure that the external assembly cover 3 is assembled on the storage barrel 1, while the combination of the internal thread B15 and the external thread B22 can ensure that the internal assembly cover 2 is stably assembled on the inside of the barrel mouth 11.

[0041] On the basis of the above technical solutions, in order to ensure that the stirring shaft 51 and the driving shaft 61 can be stably installed in a relatively rotating manner and realize the power connection with the rotating seat 4, the following technical solutions are provided.

[0043] The setting of the assembly circular groove 16 can be plugged into and combined with the bottom end of the stirring shaft 51, and ensure the stable rotation of the stirring shaft 51. The rotating seat 4 can realize power connection with the drive shaft 61 and the stirring shaft 51 through the upper spline groove 41 and the lower spline groove 42 opened thereon, thereby ensuring that the power of the drive shaft 61 can be stably transmitted to the stirring shaft 51 through the rotating seat 4.

[0044] At the same time, the structural characteristics of the rotating seat 4 also facilitate quick plug-in combination with the stirring shaft 51 and the driving shaft 61.
