[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1-Figure 4 The utility model provides an anti-clogging atomizing nozzle structure for an engine, comprising:

[0024] The spoiler tube 1 is used to be fixedly connected to the side wall of the engine combustion chamber 2, with one end of the spoiler tube 1 extending into the engine combustion chamber 2 and the other end extending outside the side wall of the engine combustion chamber 2;

[0025] The nozzle 3 is located in the spoiler tube 1, with the spray end of the nozzle 3 facing the engine combustion chamber 2, and a distance is provided between the spray end of the nozzle 3 and the end of the spoiler tube 1 located in the engine combustion chamber 2;

[0026] Support member 4, which is used to fix the nozzle 3 in the spoiler tube 1;

[0027] The spoiler tube 1 is installed on the side wall of the engine combustion chamber 2 and extends into its inner cavity. The nozzle 3 is fixed in the spoiler tube 1 by the support member 4, so that the oil mist sprayed by the nozzle 3 enters the engine combustion chamber 2 through the spoiler tube 1 for combustion; at the same time, a distance is provided between the injection end of the nozzle 3 set in the present application and the front end of the spoiler tube 1, so the front end of the spoiler tube 1 forms a protection for the nozzle 3. When the engine is running, the front end of the spoiler tube 1 will block the airflow inside the combustion chamber and will not let the gas in this part flow to the inside of the nozzle 3, thereby greatly reducing the blockage of the nozzle 3.

[0028] According to a further optimized solution, the support member 4 includes a connecting plate 5 , on which a plurality of claws 6 are fixed. The claws 6 are arranged around the nozzle 3 , and the claws 6 extend into the spoiler tube 1 . The connecting plate 5 is located outside the spoiler tube 1 .

[0029] According to a further optimized solution, when the nozzle 3 is located in the spoiler tube 1 , the claws 6 are clamped between the nozzle 3 and the inner wall of the spoiler tube 1 , and a gap 7 is left between the nozzle 3 and the inner wall of the spoiler tube 1 .

[0030] When the nozzle 3 is located inside the spoiler tube 1, the oil pipe on the nozzle 3 is located outside the spoiler tube 1, and the oil pipe passes through the gap between two adjacent claws 6 and is connected to the oil filter element 8;

[0031] When installing the nozzle 3, multiple claws 6 are wrapped around the outside of the nozzle 3, and then the claws 6 are inserted into the spoiler tube 1, so that the nozzle 3 is stuck in the spoiler tube 1 through the claws 6, thereby fixing the nozzle 3. This fixing method is simple and easy to operate; and after the nozzle 3 is fixed, due to the presence of the claws 6, there is a gap 7 between the nozzle 3 and the inner wall of the spoiler tube 1. During ignition and combustion, fresh air from the outside can pass through the gap 7 between the nozzle 3 and the inner wall of the spoiler tube 1 to achieve outward-inward flow, thereby further reducing the flow of air from the engine combustion chamber 2 into the nozzle 3, thereby further reducing the retention of carbon deposits at the nozzle 3 position.

[0032] Further optimized, the point where the axis of the spoiler tube 1 intersects with the outer wall of the engine combustion chamber 2 is the intersection point, the line connecting the intersection point to the center of the engine combustion chamber 2 is the intersection line, and the angle between the intersection line and the axis of the spoiler tube 1 is an acute angle;

[0033] Through the above arrangement, the spoiler tube 1 is installed obliquely, and the inclination direction of the spoiler tube 1 is kept in the same direction as the rotational flow direction of the spiral air in the engine combustion chamber 2, thereby further reducing the retention of carbon deposits in the air inside the engine combustion chamber 2 at the nozzle 3.

[0034] According to a further optimized solution, the claw 6 is a metal claw with slight elasticity.

[0035] A further optimized solution is that two spoiler pipes 1 are provided on the outer wall of the engine combustion chamber 2, and the two spoiler pipes 1 are symmetrically arranged along the axis of the engine combustion chamber 2; the nozzles 3 in the spoiler pipes 1 are respectively connected to the same oil filter element 8 through oil pipes.

[0036] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0037] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
