The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] First embodiment

[0022] See also Figure 1 and Figure 2 , Figure 1 It is an overall structural diagram of the three-way catalytic converter of the first embodiment of the present utility model. Figure 2 It is a projection diagram of the three-way catalytic converter of the first embodiment of the present utility model.

[0023] The present invention provides a three-way catalytic converter comprising a treatment body 101, a gas guide assembly, and a mounting assembly. The mounting assembly comprises a mounting inner shell 102, a fixed outer shell 103, an air inlet 104, and an air outlet 105. The treatment body 101 has a plurality of adsorption holes 106. The aforementioned solution solves the problem of unstable carrier installation. It is understood that the aforementioned solution can be used to ensure normal use, and can also be used to solve the problem of gas guidance failure.

[0024] In this embodiment, the processing body 101 performs oxidation-reduction on harmful gases in automobile exhaust.

[0025] Among them, the mounting inner shell 102 is fixedly connected to the processing body 101 and is located on one side of the processing body 101, the fixed outer shell 103 is fixedly connected to the mounting inner shell 102 and is located on a side of the mounting inner shell 102 close to the processing body 101, the air inlet end 104 is fixedly connected to the fixed outer shell 103 and is located on a side of the fixed outer shell 103 close to the processing body 101, and the air outlet end 105 is fixedly connected to the fixed outer shell 103 and is located on a side of the fixed outer shell 103 away from the air inlet end 104. The mounting inner shell 102 is a cylindrical shell, the inner diameter of which is equal to the diameter of the processing body 101, and is fixedly arranged on the outside of the processing body 101 in an annular shape. The fixed outer shell 103 is a cylindrical shell, the inner diameter of which is equal to the outer diameter of the mounting inner shell 102, and the fixed outer shell 103 is fixedly arranged on the outer surface of the mounting inner shell 102. The air inlet end 104 is conical and is fixedly arranged on the fixed outer shell 103. The left end of the gas outlet end 105 is conical and is fixedly arranged on the right side of the fixed outer shell 103. The exhaust gas of the automobile enters the installation inner shell 102 along the air inlet end 104 and is discharged along the gas outlet end 105 after being processed by the processing body 101. The installation inner shell 102 performs preliminary fixation on the processing body 101, and the fixed outer shell 103 performs secondary fixation on the installation inner shell 102, so that the installation of the processing body 101 is more stable, thereby ensuring normal use.

[0026] Secondly, the adsorption holes 106 are located on a side of the processing body 101 near the air inlet end 104 and penetrate the processing body 101. There are multiple adsorption holes 106, which are evenly arranged on the processing body 101 and penetrate the adsorption holes 106. The uniform arrangement of the adsorption holes 106 allows the processing body 101 to more thoroughly adsorb the exhaust gas.

[0027] When using the three-way catalytic converter of the present invention, automobile exhaust enters the installation inner shell 102 along the air inlet end 104. After being processed by the treatment body 101, the treatment body 101 adsorbs the exhaust more thoroughly through the uniform arrangement of the adsorption holes 106, and the treated exhaust is discharged along the air outlet end 105. The installation inner shell 102 performs preliminary fixation on the treatment body 101, and the fixed outer shell 103 performs secondary fixation on the installation inner shell 102, thereby making the installation of the treatment body 101 more stable, thereby ensuring normal use.

[0028] Second embodiment

[0029] See also Figure 3 and Figure 4 , Figure 3 It is an overall structural diagram of a three-way catalytic converter according to the second embodiment of the present utility model. Figure 4 This is a projection diagram of a three-way catalytic converter according to the second embodiment of the present invention. Based on the first embodiment, the air guide assembly includes a first air intake duct 201, a second air intake duct 202, and an air outlet duct 205.

The first intake duct 201 is a cylindrical duct fixedly disposed on the intake end 104, and the second intake duct 202 is a cylindrical duct fixedly disposed on the intake end 104 and close to the first intake duct 201. The arrangement of the first intake duct 201 and the second intake duct 202 allows exhaust gas to enter the processing body 101 along the first intake duct 201 and the second intake duct 202, respectively, thereby ensuring more uniform intake.

[0031] Secondly, the first air intake hole 203 is located on a side of the air intake end 104 near the first air intake duct 201 and passes through the air intake end 104. The second air intake hole 204 is located on a side of the air intake end 104 near the second air intake duct 202 and passes through the air intake end 104. The first air intake hole 203 is a circular through-hole, the size of which matches the size of the first air intake duct 201, and is provided through the air intake end 104. The second air intake hole 204 is a circular through-hole, the size of which matches the size of the second air intake duct 202, and is provided through the air intake end 104. The provision of the first air intake hole 203 and the second air intake hole 204 respectively ensures more accurate installation of the first air intake duct 201 and the second air intake duct 202.

The outlet hole 206 is located on a side of the outlet end 105 close to the outlet conduit 205 and passes through the outlet end 105. The outlet conduit 205 is a cylindrical conduit fixedly disposed on the outlet end 105. The outlet hole 206 is a circular hole, the size of which matches that of the outlet conduit 205 and passes through the outlet end 105. The provision of the outlet conduit 205 allows the treated exhaust gas to be discharged along the outlet conduit 205, thereby making the exhaust gas discharge more convenient. The provision of the outlet hole 206 also allows the outlet conduit 205 to be more accurately installed.

[0033] When using the three-way catalytic converter of the present invention, the exhaust gas can enter the processing body 101 along the first intake duct 201 and the second intake duct 202 respectively, thereby making the intake more uniform. The first intake through-hole 203 and the second intake through-hole 204 can respectively make the installation of the first intake duct 201 and the second intake duct 202 more accurate. The exhaust gas can be discharged along the exhaust duct 205 after treatment through the exhaust duct 205, thereby making the discharge of the exhaust gas more convenient. The exhaust through-hole 206 can be provided to make the installation of the exhaust duct 205 more accurate.
