[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0016] like Figure 1-8 As shown, this utility model proposes a self-priming automotive three-way catalytic converter cleaning device, which mainly consists of a main housing 1 and a fixing component 2, a leak-sealing component 3, a switching component 4, a flushing component 5, and a drying component 6 integrated thereon. The components work together through mechanical connections and pipeline arrangements. The specific implementation method is as follows: The main housing 1 is a rectangular frame structure with support legs 15 welded vertically at the four corners of the bottom. Sliding sleeve 10 is vertically fixed at the center of the bottom plate of the main housing. Sliding sleeve 21 is symmetrically arranged in the middle of the two side walls and sliding sleeve 312 is arranged at the top. Sliding sleeve 312 has symmetrical through slots 14 on both sides for hoses to pass through. The lower wastewater slide plate 13 is installed at an angle on the front and rear sides of the main housing by bolts. Its lower end extends to the outside to facilitate the rapid diversion of cleaning wastewater. The fixing components 2 are symmetrically arranged on both sides of the main housing. Each fixing component 2 includes a telescopic cylinder 20, which is set on the outer wall of the main housing. The telescopic rod of the telescopic cylinder 20 extends into the main housing through the guide hole of the sliding sleeve 11. The top of the rod is fastened with an arc-shaped clamping plate 21. The inner wall of the arc-shaped clamping plate 21 is pasted with an anti-slip pad 22 to ensure that the three-way catalytic converter is clamped and provided with anti-slip buffer to avoid surface damage. The leak-sealing component 3 is located below the bottom plate of the main housing. The cylinder body of the telescopic cylinder 2 30 is fixed to the bottom plate. The telescopic rod passes vertically upward through the sliding sleeve 10, and its top end is connected to the plug 31. The edge of the plug 31 port is embedded with an annular sealing ring 32. The switching component 4 is installed on the top of the main housing. The cylinder body of the telescopic cylinder 3 40 is fixed to the top plate of the main housing. The telescopic rod extends vertically downward through the sliding sleeve 3 12. The top of the rod is connected to the mounting bracket 41. The mounting bracket 41 is equipped with a motor 42. The transmission end of the motor 42 passes through the center hole at the bottom of the mounting bracket 41. A fixing plate 43 is provided. Mounting positions are reserved on both sides for fixing the corresponding parts of the rinsing component 5 and the drying component 6. In the flushing assembly 5, the water pump 51 and the water tank 50 are fixed on the top side of the main housing. The bottom of the water tank 50 is connected to the water inlet of the water pump 51 through a rigid pipe. The water outlet of the water pump 51 is connected to the first hose 52. The first hose 52 passes through the through groove 14 on one side of the sliding sleeve 12. Its top end is connected to the water outlet cover 53. The water outlet cover 53 is welded to the bottom side of the fixed plate 43. In the drying assembly 6, the blower 60 is fixed to the other side of the top of the main housing, the air outlet is connected to the processing pipe 61, the heating wire 62 is horizontally installed inside the processing pipe 61, the other end of the processing pipe 61 is connected to the second hose 63, the second hose 63 passes through the through groove 14 on the other side of the sliding sleeve 12, and its top end is fixed to the air outlet hood 64, which is welded to the other side of the bottom of the fixing plate 43.

[0017] When using it, the user first places the three-way catalytic converter to be cleaned horizontally between the two fixed components 2 of the cleaning device. The user then starts the two synchronously operating telescopic cylinders 20 through the operation controller. The telescopic cylinders 20 drive the telescopic rod to extend horizontally, which moves the arc-shaped clamping plate 21 towards the center. The arc-shaped clamping plate 21 and the outer surface of the catalytic converter are designed to fit together to form a ring-shaped clamping, which achieves stable fixation. At the same time, the anti-slip rubber pads 22 on the surface of the arc-shaped clamping plate 21 can prevent damage to the outer shell of the catalytic converter. After fixing, the telescopic cylinder 30 is activated by the controller. Its telescopic rod extends vertically downward, pushing the plug 31 to press against the bottom port of the three-way catalytic converter. The sealing ring 32 tightly fits the catalytic converter port to prevent subsequent cleaning fluid leakage. Operators slowly pour oxalic acid solution into the top port of the three-way catalytic converter through a funnel or a special filling port, ensuring that the cleaning solution completely submerges the internal honeycomb carrier and catalyst coating. A timer is set to control the soaking time to 30-60 minutes, so that the oxalic acid can fully dissolve stubborn impurities such as carbon deposits and sulfur and phosphorus compounds attached to the surface of the carrier. After soaking, the telescopic cylinder 2 30 retracts to discharge the residual oxalic acid solution. Then, the motor 42 starts and drives the fixed plate 43 to rotate 90 degrees, so that the top water outlet 53 is aligned with the top port of the three-way catalytic converter. Then, the telescopic cylinder 3 40 is activated, pushing the telescopic rod down to tightly fit the water outlet cover 53 at the port. The water pump 51 draws clean water from the water tank 50 and injects it into the water outlet cover 53 through the hose 1 52 to rinse the inside of the catalyst. The loose dirt is peeled off and slides down the dirt slide plates 13 on both sides into the dirt collection tank. After rinsing, telescopic cylinder 3 40 retracts, motor 42 rotates 90 degrees in the opposite direction, aligning the air outlet 64 with the top port of the three-way catalytic converter. Telescopic cylinder 3 40 then moves again, fixing the air outlet 64 to form a sealed channel. Heating wire 62 and blower 60 are activated. Blower 60 sends ambient air into treatment pipe 61, which is heated by heating wire 62 and then delivered to air outlet 64 through hose 2 63. The hot air penetrates the inside of the catalytic converter at a constant flow rate, carrying away residual moisture.
