## Abstract

A gas treatment system for a vehicle contains: a gas charging unit, a gas exhausting unit, and a tail gas treating unit. The gas charging unit includes a plurality of air inlets arranged on a roof and a peripheral side of the vehicle and communicating with a body of the vehicle, the plurality of air inlets also connect with an air inlet channel for charging fresh air. The gas exhausting unit includes a gas discharge channel for discharging waste gas, and the gas discharge channel has an outlet segment arranged on an upper side thereof and extending out of a top surface of a tail end of the vehicle. The tail gas treating unit includes an electrode absorber disposed on a lower end of the outlet segment of the gas discharge channel to treat the waste gas from the gas discharge channel.

## Claims

### Claim 1

A gas treatment system for a vehicle comprising: a gas charging unit, a gas exhausting unit, and a tail gas treating unit:
wherein the gas charging unit includes a plurality of air inlets arranged on a roof and a peripheral side of the vehicle and communicating with a body of the vehicle, the plurality of air inlets also connect with an air inlet channel for charging fresh air;
wherein the gas exhausting unit includes a gas discharge channel for discharging waste gas, and the gas discharge channel has an outlet segment arranged on an upper side thereof and extending out of a top surface of a tail end of the vehicle;
wherein the tail gas treating unit includes a negative oxygen ion generator disposed on a lower end of the outlet segment of the gas discharge channel to treat the waste gas from the gas discharge channel;
wherein the roof includes a water isolation plate formed in an inverted V shape so as to stop rainwater flowing into the vehicle and to facilitate heat dissipation;
wherein the outlet segment of the gas discharge channel has a rainwater shield rotatably connected thereon; and
wherein the negative oxygen ion generator of the tail gas treating unit has a collection tray disposed on the tail end of the vehicle by using a support mount and located below the outlet segment of the gas discharge channel, such that the negative oxygen ion generator sprays negative oxygen ion to neutralize the waste gas.

### Claim 2 (depends on 1)

The gas treatment system for the vehicle as claimed in claim 1, wherein the gas discharge channel also has a silencer fixed on an intermediate section thereof and has at least one curved portion, and a bending angle of each curved portion of the gas discharge channel is 45 to 90 degrees, wherein a number of the at least one curved portion is 2.

### Claim 3 (depends on 1)

The gas treatment system for the vehicle as claimed in claim 1, wherein the gas charging unit further includes an air inflow segment formed on a bottom surface of the tail end of the vehicle in front of an engine, and the air inflow segment has an arcuate wind deflector.

### Claim 4 (depends on 1)

The gas treatment system for the vehicle as claimed in claim 1, wherein the gas exhausting unit further includes two air guiding portions arranged in a middle section of the tail end of the vehicle, and each air guiding portion has at least one wind wire, and a cross section of the least one wind wire is in any one of an L shape, a T shape, a square shape, a triangle shape, a circle shape, and a semicircle shape.

### Claim 5 (depends on 1)

The gas treatment system for the vehicle as claimed in claim 1, wherein the collection tray is integrally molded from flame retardant plastic or stainless steel and has a locking slot defined on a bottom thereof to retain with the support mount, and the collection tray has water and a sponge accommodated therein.

### Claim 6 (depends on 1)

The gas treatment system for the vehicle as claimed in claim 1, wherein the gas charging unit includes a rectangular waterproof cover supported on the roof of the vehicle above the plurality of air inlets by plural holding stands, and the gas charging unit also includes a stop plate fixed between the waterproof cover and the roof of the vehicle so as to stop rainwater flowing into the plurality of air inlets.

### Claim 7 (depends on 6)

The gas treatment system for the vehicle as claimed in claim 6, wherein the air inlet channel is rigid.

### Claim 8 (depends on 7)

The gas treatment system for the vehicle as claimed in claim 7, wherein the waterproof cover includes a support rack and a cap, wherein the support rack is a square tube or is in an L shape, and the support rack is made of stainless steel; the cap has a first watertight line formed in a U shape and arranged on each of two sides thereof, and the air inlet channel also has a second watertight line formed in an L shape and disposed on an upper end thereof, each air inlet has a flat bottom or a tilted bottom.
