Description

Technical Field

[0001] The utility model relates to the technical field of automobile maintenance, in particular to an automobile tailpipe cleaning structure. Background Art

[0002] Automobile exhaust is the waste gas generated when the car is in use. It contains hundreds of different compounds, among which the pollutants include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides. These substances are discharged from the car through the exhaust pipe. Long-term emission of these substances will cause the inner wall of the exhaust pipe to be covered with dust stains that are difficult to clean. Long-term accumulation of dust stains will easily reduce exhaust emissions. The exhaust gas is blocked in the exhaust pipe, which will cause damage to the vehicle's power equipment.

[0023] Example:

[0024] Reference Figure 1-Figure 4A car exhaust pipe cleaning structure includes a main pipe 1 and a flexible sleeve 2. The flexible sleeve 2 is made of plastic, rubber or nylon, preferably plastic. A metal wire mesh layer is fixedly arranged in the flexible sleeve 2, so that the flexible sleeve 2 has a certain flexibility and a certain strength to ensure reliable operation. One end of the flexible sleeve 2 is fixedly connected to the main tube 1, a flexible shaft 3 is rotatably arranged in the flexible sleeve 2, a motor for driving the flexible shaft 3 to rotate is arranged in the main tube 1, and a power supply and a charging port are fixedly arranged in the main tube 1 to facilitate power supply to the motor, and a button is arranged on the outer wall of the main tube 1 to facilitate control of the rotation of the motor; a connecting seat 4 is rotatably arranged at the other end of the flexible sleeve 2, a cleaning brush 5 is arranged on the connecting seat 4, and the end of the flexible shaft 3 away from the motor is fixedly connected to the connecting seat 4. When in use, the flexible sleeve 2 is fixedly arranged in the main tube 1, and the flexible shaft 3 is rotatably arranged in the flexible sleeve 2. Then, when the flexible shaft 3 drives the connecting seat 4 and the cleaning brush 5 to rotate, on the one hand, the connecting seat 4 and the cleaning brush 5 can be extended into the curved exhaust pipe to reduce the influence of the shape of the exhaust pipe and improve the scope of use. On the other hand, the rotating cleaning brush 5 can improve the cleaning quality of the inner wall of the exhaust pipe.

[0025] Reference Figure 2 A mounting groove 401 is provided on the outer wall of the connecting seat 4, and the mounting groove 401 is in a T-shaped structure. A cleaning plate 501 is slidably arranged in the mounting groove 401. The cleaning brush 5 is extended into the mounting groove 401 and fixedly connected to the cleaning plate 501, and an end cover 7 for limiting the sliding of the cleaning plate 501 is provided on one end of the connecting seat 4. When in use, the cleaning brush 5 is fixed on the cleaning plate 501, and then the cleaning plate 501 is slid into the mounting groove 401, and the end cover 7 for limiting the sliding of the cleaning plate 501 is threadedly connected to the connecting seat 4. On the one hand, it is convenient to replace the cleaning brush 5 and improve the cleaning quality. On the other hand, during use, the cleaning plate 501 can be prevented from sliding to ensure normal operation.

[0026] Reference Figure 2 A screw rod 701 is fixedly provided on the end cover 7, the screw rod 701 is threadedly connected to the connecting seat 4, and one end of the cleaning plate 501 is abutted against the end cover 7. When in use, the end cover 7 is threadedly connected to the connecting seat 4 through the screw rod 701, which makes assembly and disassembly more convenient, facilitates the replacement of the cleaning brush 5, and improves the use effect.

[0027] Reference Figure 2 and Figure 3A rotation groove is provided at the other end of the flexible sleeve 2, and a plurality of groups of sliding blocks 402 are fixedly provided on the other end of the connecting seat 4. The sliding blocks 402 are provided in two to six groups. Here, we prefer three groups, and the three groups are evenly distributed. The three groups of sliding blocks 402 are all slidably provided in the rotation groove. When in use, by providing a rotation groove on the flexible sleeve 2 and fixing the sliding blocks 402 on the connecting seat 4, the reliable rotation of the connecting seat 4 can be ensured, thereby improving the use effect.

[0028] Reference Figure 2-Figure 4 A sliding seat 6 is sleeved on the outer wall of the flexible sleeve 2, a guide groove 601 is opened in the sliding seat 6, a limit plate 801 is slidably set in the guide groove 601, and a pressing rod 8 is fixedly set on the limit plate 801, one end of the pressing rod 8 is pressed against the outer wall of the flexible sleeve 2, and a pressing plate 803 is fixedly set at the other end of the pressing rod 8. When in use, after the connecting seat 4 and the cleaning brush 5 are inserted into the exhaust pipe, the sliding seat 6 is held and the pressing plate 803 is pressed, so that the pressing rod 8 is pressed against the outer wall of the flexible sleeve 2. At this time, the flexible sleeve 2 can be controlled to swing or move through the sliding seat 6 to improve the cleaning effect. Since a metal wire mesh layer is fixedly set in the flexible sleeve 2, when the pressing rod 8 is pressed to press the flexible sleeve 2, the flexible sleeve 2 will not be significantly deformed, avoiding affecting the rotation of the flexible shaft 3.

[0029] Reference Figure 4 A spring 802 is sleeved on the pressing rod 8, and the two ends of the spring 802 are respectively pressed against the guide groove 601 and the limit plate 801. When in use, when the sliding seat 6 is used up, the pressing of the pressing plate 803 is released. Under the elastic force of the spring 802, the pressing plate 803 and the pressing rod 8 return to their original positions, that is, one end of the pressing rod 8 is away from the state of pressing against the outer wall of the flexible sleeve 2. At this time, it is easy to drive the sliding seat 6 to slide on the flexible sleeve 2, and it can also avoid scratches on the outer wall of the flexible sleeve 2, thereby improving the use effect.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
