The following embodiments are used to illustrate this utility model.
[0028] like Figure 1 As shown, a car wax spraying exhaust gas treatment device includes: a wax spraying chamber 20, which is a hollow rectangular cavity. A blower is fixedly connected to the bottom of one side of the wax spraying chamber 20, and the blower can communicate with the bottom of the cavity inside the wax spraying chamber 20. An exhaust fan 23 is fixedly connected to the bottom of the other side of the wax spraying chamber 20. A gas collection pipe 21 is fixedly connected to the rear wall of the wax spraying chamber 20.

The car is waxed inside the wax spraying chamber 20. Both the exhaust fan 23 and the blower are electrically connected to a power source. This is existing technology and will not be described in detail here.
[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the treatment structure is installed on the side wall of the wax spraying chamber 20 for filtering the exhaust gas inside the wax spraying chamber 20. The treatment structure includes: a treatment chamber 30, an upper pipe 31, a booster pipe 32, a nozzle 33, a rear pipe 36, and an activated carbon plate 41. The treatment chamber 30 is fixedly connected to the wall of the support 22. The upper pipe 31 is fixedly connected to the side wall of the gas collection pipe 21. The booster pipe 32 is fixedly connected to the top of the treatment chamber 30. The nozzle 33 is installed inside the cavity of the treatment chamber 30. The rear pipe 36 is fixedly connected to the exhaust port of the exhaust fan 23. The activated carbon plate 41 is installed on the wall of the rear pipe 36. The upper pipe 31 and the rear pipe 36 can communicate with the cavity of the treatment chamber 30.
[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the processing chamber 30 is a hollow rectangular box with an open bottom. An upper pipe 31 connects to the top of the processing chamber 30, and the other end of the upper pipe 31 connects to the gas collection pipe 21. A pressurization pipe 32 connects to the nozzle 33, and a rear pipe 36 connects to the rear wall of the processing chamber 30. The nozzle 33 is located behind the top of the processing chamber 30. The processing structure also includes a partition 34, a drain pipe 35, and a bottom box 37. The partition 34 is fixedly connected to the inner wall of the processing chamber 30, the drain pipe 35 is fixedly connected to the front wall of the processing chamber 30, and the bottom box 37 is installed at the bottom of the processing chamber 30. The partition 34 is a rectangular plate with multiple circular holes extending through its upper half. The partition 34 is placed obliquely within the processing chamber 30. Inside, the front wall slope of the partition 34 can be aligned with the rear end of the drain pipe 35. The bottom box 37 is a hollow rectangular box with an open top. The top opening of the bottom box 37 can be adapted to the bottom size of the treatment chamber 30. A threaded groove is opened on the rear wall of the bottom box 37. A bolt is installed in the threaded groove on the wall of the bottom box 37. The bolt on the wall of the bottom box 37 can abut against the rear wall of the treatment chamber 30. A sealing strip is installed inside the cavity of the bottom box 37. The wall of the rear pipe 36 is provided with a disassembly structure. The disassembly structure includes a frame 42, a slot 43 and a rear frame 40. The frame 42 is fixedly connected to the wall of the rear pipe 36. The slot 43 is opened at the bottom of the frame 42. The rear frame 40 is fixedly connected to the top of the rear wall of the bottom box 37. The activated carbon plate 41 can be fixedly connected to the top of the rear frame 40.
[0031] In practical use, the booster pipe 32 is connected to the water supply pipe, and then the drain pipe 35 is connected to the sewage pipe. The power is then turned on. When the power is on, the blower supplies air into the wax spraying chamber 20, while the exhaust fan 23 draws air out. The exhaust fan 23, through the cooperation of the rear pipe 36, the treatment chamber 30, the upper pipe 31, and the air collection pipe 21, draws the exhaust gas from the wax spraying chamber 20 towards itself. The exhaust gas, after passing through the air collection pipe 21 and the upper pipe 31, enters the treatment chamber 30. At this time, the booster pump installed in the booster pipe 32 sprays water from the water supply pipe into the treatment chamber 30 through the nozzle 33. When exhaust gas is introduced into the treatment chamber 30, the water mist sprayed by the nozzle 33 comes into contact with the exhaust gas. When the exhaust gas comes into contact with the water mist, large particles in the exhaust gas fall and accumulate on the top of the bottom box 37 at the bottom of the treatment chamber 30. The collected water will leak down from the round holes on the wall of the partition 34 and be discharged into the sewage pipe through the drain pipe 35. The filtered waste gas will be drawn into the cavity of the rear pipe 36 by the suction of the rear pipe 36. When the waste gas passes through the cavity of the rear pipe 36, it will come into contact with the activated carbon plate 41. At this time, the activated carbon plate 41 will adsorb and filter the waste gas. Then the purified gas after adsorption and filtration will be discharged by the exhaust fan 23. When it is necessary to clean the cavity of the treatment chamber 30, the bolts on the wall of the bottom box 37 will be unscrewed. At this time, the bottom box 37 can be removed from the bottom of the treatment chamber 30. At this time, large particles filtered out will accumulate in the cavity of the bottom box 37. As the bottom box 37 is removed, the rear frame 40 and the activated carbon plate 41 will be separated from the bottom of the frame 42. At this time, the activated carbon plate 41 can also be cleaned or replaced. Then the bottom box 37 can be reinstalled at the bottom of the treatment chamber 30 through the bolts on its wall.
[0032] In summary, by setting up a treatment structure, the wax spraying exhaust gas can be purified through water spraying combined with adsorption and filtration by activated carbon plate 41. Compared with the existing technology, this solution not only has a better treatment effect, but also eliminates the need for frequent replacement of activated carbon plate 41 by sharing the workload of activated carbon plate 41.
[0033] like Figure 5 As shown, the middle section of the rear tube 36 has an opening, the frame 42 is located in the opening on the wall of the rear tube 36, the frame 42 is semi-circular, the slot 43 is opened on the bottom inner arc surface of the frame 42, the rear frame 40 is a T-shaped plate, the top size of the rear frame 40 can fit with the bottom of the frame 42, the upper part of the activated carbon plate 41 can be snapped into the slot 43, and the top of the rear frame 40 can fill the opening of the rear tube 36 below the frame 42.
[0034] In actual use, as the bottom box 37 is removed, the rear frame 40 and the activated carbon plate 41 will be simultaneously separated from below the card frame 42.
[0035] In summary, by setting up a disassembly structure to bind the activated carbon plate 41 and the bottom box 37, the activated carbon plate 41 can be easily cleaned or replaced when cleaning the bottom box 37, thus effectively improving the convenience of using this device.
[0036] Working principle: When the power is turned on, the blower supplies air into the wax spraying chamber 20, while the exhaust fan 23 draws in air. The exhaust fan 23, through the cooperation of the rear pipe 36, the treatment chamber 30, the upper pipe 31, and the air collection pipe 21, draws the exhaust gas from the wax spraying chamber 20 towards itself. The exhaust gas, after passing through the air collection pipe 21 and the upper pipe 31, enters the treatment chamber 30. At this time, a booster pump installed in the booster pipe 32 sprays water from the water supply pipe into the treatment chamber 30 through the nozzles 33. When exhaust gas is introduced into the treatment chamber 30, the nozzles 33... The sprayed water mist comes into contact with the exhaust gas. When the exhaust gas comes into contact with the water mist, the large particles in the exhaust gas fall and accumulate on the top of the bottom box 37 at the bottom of the treatment chamber 30. The water collected in the treatment chamber 30 will leak down from the round hole on the wall of the partition 34 and be discharged into the sewage pipe through the drain pipe 35. The filtered exhaust gas will enter the rear passage pipe 36 through the suction of the rear passage pipe 36. When the exhaust gas passes through the rear passage pipe 36, it will come into contact with the activated carbon plate 41. At this time, the activated carbon plate 41 will adsorb and filter the exhaust gas. Then the purified gas after adsorption and filtration will be discharged by the exhaust fan 23.
