[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0023] like Figure 1As shown, the dual-chamber exhaust gas processor includes an intake pipe 1, a fixing mechanism 3 and two purification mechanisms 2.

[0024] The two purification mechanisms 2 are symmetrically arranged, and the purification mechanism 2 includes a cavity 21, a filter screen 22 and a catalytic component 23. The cavity 21 is provided with an air inlet 211, a filter outlet 212 and an air outlet 213. The air inlet 211 is located at the top of the cavity 21, the filter outlet 212 is located in the middle of the cavity 21, and the air outlet 213 is located at the bottom of the cavity 21. The air inlet 211 is connected to the intake pipe 1.

[0025] The filter screen 22 is slidably disposed on the cavity 21 , and the filter screen 22 is tilted. The end of the filter screen 22 away from the filter outlet 212 is higher than the end close to the filter outlet 212 , and the end of the filter screen 22 close to the filter outlet 212 extends out of the filter outlet 212 . A protrusion 221 is disposed at the bottom of the filter screen 22 .

[0026] The fixing mechanism 3 is used to fix the filter screen 22 on the cavity 21. Figure 2 As shown, the fixing mechanism 3 includes a fixing box 31, a fixing block 32, a shift rod 33, and a spring 34. The fixing box 31 is fixedly arranged on the outer wall of the cavity 21, and the fixing box 31 is located below the filter outlet 212. A through hole is arranged on the top of the fixing box 31, and a slide groove is arranged on the side wall of the fixing box 31. The fixing block 32 is arranged on the fixing box 31, and is vertically slidable along the through hole. A slope is arranged on the top of the fixing block 32 away from the cavity 21, and the fixing block 32 is correspondingly engaged with the protrusion 221. The shift rod 33 is fixedly arranged on the fixing block 32, and the shift rod 33 is horizontally arranged. One end of the shift rod 33 extends out of the slide groove, and is vertically slidable along the slide groove. The spring 34 is located in the fixing box 31, and the two ends of the spring 34 are respectively in contact with the shift rod 33 and the fixing box 31, giving the shift rod 33 an upward elastic force. As shown Figure 3 As shown, in other embodiments, the number of fixing mechanisms 3 can be multiple. When there are multiple fixing mechanisms 3, a connecting rod 4 can be further provided. The connecting rod 4 is used to connect the shift rods 33 on multiple fixing mechanisms 3. The multiple fixing mechanisms 3 can be controlled simultaneously by moving the connecting rod 4.

[0027] The catalytic assembly 23 includes a plurality of baffles 231, which are arranged crosswise at the rear of the cavity 21, i.e., near the gas outlet 213, and a serpentine channel is formed between the baffles 231. In actual use, two filter plates 232 may be arranged, one of which is used to connect the baffle 231 at the top and the side wall of the cavity 21, and the other filter plate 232 is used to connect the baffle 231 at the bottom and the side wall of the cavity 21. The two filter plates 232 are used to isolate the catalyst in the serpentine channel without affecting the discharge of the gas. In other embodiments, in order to facilitate the replacement of the catalyst, one of the side walls of the cavity 21 may be arranged to be detachable, and when the catalyst needs to be replaced, the side wall is removed; in normal use, all the side walls of the cavity 21 and the baffles 231 form a serpentine channel, which increases the contact time between the catalyst and the exhaust gas, and is beneficial to the treatment of the exhaust gas.

[0028] When the utility model is in use, automobile exhaust gas enters the two cavities 21 through the air intake pipe 1, and firstly filters out impurities through the filter screen 22, and the impurities are discharged from the filter outlet 212 along the filter screen 22. After passing through the filter screen 22, the automobile exhaust gas enters the catalytic component and moves along the serpentine channel to the outlet 213, and the purified exhaust gas is discharged from the outlet 213. When the filter 22 needs to be replaced, the lever 33 is moved downward, and the lever 33 drives the fixing block 32 to move downward to make way for the protrusion 221. At the same time, the filter 22 can be pulled outward to complete the disassembly. During installation, the filter 22 is made to slide along the slide rail into the cavity 21. Due to the setting of the inclined surface on the fixing block 32, when the protrusion 221 contacts the fixing block 32, the fixing block 32 slides downward. When the protrusion 221 is located on the other side of the fixing block 32, the elastic force of the spring 34 drives the lever 33 to move upward, and the lever 33 drives the fixing block 32 to move upward, that is, the fixing block 32 clamps the protrusion 221, completing the process of fixing the filter 22 by the fixing mechanism 3.

[0029] In the present invention, the setting of the fixing mechanism 3 facilitates the disassembly and assembly of the filter screen 22. Compared with other methods of fixing by bolts, not only does the disassembly and assembly process not require the use of other tools, but it can also avoid the problem of unstable fixing caused by bolt thread slippage. The operation is simple and convenient, and the use of the fixing mechanism 3 of the present invention to fix the filter screen 22 is more stable. The setting of the partition 231 can increase the reaction time between the exhaust gas and the catalyst, and play a better role in purifying the exhaust gas.

[0030] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
