Description

Technical Field

[0001] The utility model relates to the technical field of motor vehicle accessories, in particular to an electronic regulating and purifying device for motor vehicle exhaust. Background Art

[0002] Motor vehicles usually emit motor vehicle exhaust gas during driving. Motor vehicle exhaust gas is the exhaust gas emitted by vehicles with internal combustion engines as power units during operation. During the driving of motor vehicles, the exhaust gas emitted by motor vehicles needs to be purified. The degree of purification needs to be adjusted according to the concentration of the exhaust gas. This requires the use of a motor vehicle exhaust electronic adjustment and purification device.

[0003] In the prior art, there are the following problems:

[0004] Usually, when purifying the exhaust gas of motor vehicles, most of them adopt three-way catalysis to purify the exhaust gas. However, after the three-way catalysis purifies the exhaust gas, some harmful gases still remain in the exhaust gas, and the purification method is relatively simple. The existing solution is to add another purification device to the exhaust pipe of the motor vehicle, so as to perform double purification on the exhaust gas emitted by the motor vehicle and improve the degree of purification of the motor vehicle exhaust gas. However, the existing motor vehicle exhaust purification device is not convenient to adjust the degree of filtration according to the concentration of the exhaust gas, and cannot automatically adjust the low-precision filter material to filter the exhaust gas when the exhaust gas concentration is low. At the same time, the installation and fixation are relatively troublesome. Utility Model Content

[0005] The purpose of the utility model is to provide an electronic regulating and purifying device for motor vehicle exhaust to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electronic regulating and purifying device for motor vehicle exhaust, comprising a tube body, a butt joint tube and a fixed plate, one side of the tube body is connected to the butt joint tube, the inner wall of the butt joint tube is provided with a fixing groove, a rotating rod is rotatably installed inside the tube body, a movable plate is fixedly connected to the rear end of the rotating rod, a fixing plate is fixedly installed inside the tube body on one side of the rotating rod, a first filter is fixedly connected to the front end of the fixing plate, and a second filter is fixedly installed to the rear end of the fixing plate.

[0007] By docking the docking pipe with the exhaust pipe of the motor vehicle and inserting the exhaust pipe of the motor vehicle into the fixed groove, the docking pipe and the exhaust pipe of the motor vehicle can be quickly docked, and the installation and fixing are relatively convenient. When the motor vehicle is emitting exhaust gas, when the exhaust gas concentration is low, the rotating rod is driven to rotate, and the movable plate can be synchronously flipped backward to seal the space at the rear end of the fixed plate, so that the exhaust gas can flow to the first filter for filtration. When the exhaust gas concentration is high, the rotating rod is driven to rotate, and the movable plate can be synchronously driven to flip forward, so that the space at the front end of the fixed plate can be sealed, so that the exhaust gas can flow to the second filter for filtration. The filtration accuracy of the first filter is less than that of the second filter, and the filtration purification channel can be electronically adjusted according to the exhaust gas concentration.

[0008] Preferably, mounting seats are fixedly mounted on both sides of the tube body, and mounting holes are provided on the tops of the mounting seats. By passing bolts through the mounting holes, the mounting seats can be fixed to a suitable position of the motor vehicle, and the tube body can be installed and fixed at the same time.

[0009] Preferably, a motor that cooperates with the rotating rod is fixedly installed at the bottom of the tube body, and an air outlet pipe is connected to one side of the tube body. When the motor is started, the rotating rod is driven to rotate, and the filtered and purified exhaust gas can be discharged through the air outlet pipe.

[0010] Preferably, a guide groove is provided on the inner wall of the butt joint pipe on one side of the fixing groove, and a fixing bolt extending into the fixing groove is installed on the inner thread of the butt joint pipe. The guide groove is used to guide the exhaust pipe of the motor vehicle so that the exhaust pipe of the motor vehicle is inserted into the fixing groove, and the butt joint pipe and the exhaust pipe of the motor vehicle can be quickly connected by rotating the fixing bolt.

[0011] Preferably, the front and rear ends of the inner wall of the tube body are fixedly installed with limit blocks corresponding to the movable plate, and the inner side of the butt joint tube on one side of the fixed groove is fixedly connected with a detector. The limit blocks can be used to limit the movable plate to avoid the situation where the movable plate cannot be blocked due to excessive rotation angle, and the detector is used to detect the concentration of the exhaust gas.

[0012] Preferably, the first filter screen is fixedly mounted to the fixing plate via a first fixing frame, and the second filter screen is fixedly connected to the fixing plate via a second fixing frame. The first filter screen can be fixedly mounted via the first fixing frame, and the second filter screen can be fixedly mounted via the second fixing frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By setting up the mutual cooperation among the tube body, the movable plate, the fixed plate, the first filter and the second filter, when the motor vehicle discharges the exhaust gas, the concentration of the exhaust gas is detected by the detector. When the concentration is low, the movable plate is flipped backward to block the space at the rear end of the fixed plate, so that the exhaust gas flows to the first filter for filtration. When the exhaust gas concentration is high, the movable plate is flipped forward to block the space at the front end of the fixed plate, so that the exhaust gas flows to the second filter for filtration, thereby reducing the use frequency of the second filter. The filtering accuracy of the first filter is less than that of the second filter, and the filtering purification channel can be electronically adjusted according to the exhaust gas concentration.

[0015] 2. By providing the butt-joint pipe, the fixing groove and the guide groove to cooperate with each other, the butt-joint pipe is butted against the exhaust pipe of the motor vehicle, the exhaust pipe of the motor vehicle is guided by the guide groove, and the exhaust pipe of the motor vehicle is inserted into the fixing groove. By rotating the fixing bolt, the butt-joint pipe and the exhaust pipe of the motor vehicle can be quickly butted against each other, and installation and fixing are more convenient.

DETAILED DESCRIPTION

[0024] A motor 101 cooperating with the rotating rod 3 is fixedly installed at the bottom of the tube body 1, and an air outlet pipe 102 is connected to one side of the tube body 1. A guide groove 203 is opened on the inner wall of the docking tube 2 on one side of the fixed groove 202, and a fixing bolt 204 extending into the fixed groove 202 is installed on the inner side of the docking tube 2. Limit blocks 105 corresponding to the movable plate 301 are fixedly installed at the front and rear ends of the inner wall of the tube body 1, and a detector 201 is fixedly connected to the inner side of the docking tube 2 on one side of the fixed groove 202.

[0025] The working principle of the motor vehicle exhaust electronic regulating and purifying device based on Example 1 is as follows: by docking the docking pipe 2 with the motor vehicle exhaust pipe, the motor vehicle exhaust pipe is guided by the guide groove 203, so that the motor vehicle exhaust pipe is inserted into the fixing groove 202, and the docking pipe 2 and the motor vehicle exhaust pipe are quickly docked by rotating the fixing bolt 204, so that the installation and fixing are relatively convenient;

[0026] When the motor vehicle discharges exhaust gas, the concentration of the exhaust gas is detected by the detector 201.
