AI Technical Summary
It is difficult for drivers to accurately determine whether the three-way catalyst has crashed and damaged during daily inspections, resulting in the impact of the exhaust purification function.
A purification device is designed, including a three-way catalyst, an outer protective shell and a glass shell. The outer protective shell is installed in the lower half of the three-way catalyst, and the glass shell is filled with red liquid. When the three-way catalyst collides, the glass shell breaks, the red liquid flows out and is absorbed by the non-woven fabric, causing the non-woven extension strip to dye, making it easier for the driver to judge whether the three-way catalyst collides by observing the color of the non-woven extension strip.
Convenient three-way catalytic collision detection is realized to ensure the normal operation of the exhaust gas purification device and avoid emission deterioration caused by failure to detect in time.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile exhaust purification, and in particular to a purification device. Background Art
[0002] For the exhaust treatment of motor vehicles, a three-way catalytic converter is usually installed in the exhaust system of the motor vehicle, so that the exhaust gas of the vehicle is converted into harmless carbon dioxide, water and nitrogen through oxidation and reduction through the three-way catalytic converter, so that the exhaust gas of the vehicle can be purified. Therefore, the three-way catalytic converter is an important component of the exhaust treatment of motor vehicles. Since the three-way catalytic converter is installed at the bottom of the vehicle, it is easy to be contacted and collided by foreign objects when the vehicle is driving. Once the three-way catalytic converter is damaged by collision, it may not be able to purify the exhaust gas, resulting in worsening emissions. Therefore, it needs to be repaired or replaced in time. However, due to its installation position, it cannot be effectively observed by the driver during daily inspection, so it is impossible to accurately determine whether the three-way catalytic converter has collided, which has defects.

The two limiting slots 203 are respectively slidably plugged with the two limiting plug-ins 101; the outer protective shell 2 is opened inside There is a storage cavity 209 with an arc-shaped cavity structure, and seven groups of glass shells 208 with arc-shaped block structures are evenly distributed inside the storage cavity 209. The glass shells 208 adopt an inner hollow structure, and the hollow cavity of the glass shells 208 is filled with red liquid 2010; a non-woven fabric 207 is fitted and installed on the outer peripheral surface of the storage cavity 209; the inner peripheral surface of the glass shell 208 is in contact with the inner peripheral surface of the storage cavity 209, and the outer peripheral surface of the glass shell 208 is in contact with the non-woven fabric 207. Therefore, when the glass shell 208 is broken, the red liquid 2010 flowing out of the cavity will be absorbed and conducted by the non-woven fabric 207, thereby dyeing the non-woven fabric 207 red.
[0025] In this embodiment, two strip-shaped extension shells 202 are fixedly installed on the right side of the outer protective shell 2. The strip-shaped extension shells 202 are made of flexible transparent material. The inner end surface of the storage cavity 209 relative to the two strip-shaped extension shells 202 is provided with a display connecting groove 2011; two types of non-woven fabric extension strips 206 are fixedly connected to the non-woven fabric 207, and the two non-woven fabric extension strips 206 are respectively inserted into the two display connecting grooves 2011, so the non-woven fabric extension strips 206 can be clearly observed through the strip-shaped extension shell 202.
[0026] In this embodiment, a square-shaped mounting plate 204 is fixedly mounted on the rear end of each of the two strip-shaped extension shells 202. Each of the two mounting plates 204 is provided with a mounting hole 205.

[0027] The working principle of this embodiment:
[0028] The three-way catalytic converter 1 of the present application is installed in the exhaust system of an automobile, and the automobile exhaust gas is converted into harmless carbon dioxide, water and nitrogen through oxidation and reduction by the three-way catalytic converter 1, so that the automobile exhaust gas can be purified;
[0029] The mounting block 201 is mounted and connected to the three-way catalytic converter 1 through the plug-in cooperation of the limiting slot 203 and the limiting plug block 101, so that the outer protective shell 2 is sleeved on the lower half area of the three-way catalytic converter 1, and the strip-shaped extension shell 202 extends outward along the chassis of the car, so that the tail end of the strip-shaped extension shell 202 fits the lower part of the outer surface of the car, and the fastener can be inserted through the mounting hole 205 on the mounting plate 204 and fixedly connected to the outer surface of the car, so as to achieve fixed installation of the tail end of the strip-shaped extension shell 202;
[0030] When a foreign object collides with the lower half area of the three-way catalytic converter 1, the glass shell 208 located inside the storage cavity 209 will also be shattered by the collision, so that the red liquid 2010 in the hollow cavity of the glass shell 208 flows into the storage cavity 209, and is absorbed and conducted by the non-woven fabric 207 located inside the storage cavity 209, thereby dyeing the non-woven fabric 207 and the non-woven fabric extension strip 206; therefore, when the driver checks the vehicle on a daily basis, he can observe whether the non-woven fabric extension strip 206 located in the display connecting groove 2011 is dyed through the strip-shaped extension shell 202, so as to determine whether the three-way catalytic converter 1 has a collision. When the non-woven fabric extension strip 206 is observed to be dyed, it is necessary to check the three-way catalytic converter 1 in time to determine whether it is damaged by the collision, so as to ensure that it can play the exhaust gas purification function.
