The negative pressure fresh air ion deodorization system as claimed in claim 1, wherein the control unit comprises a PLC, the PLC adjusts the rotation speed of the fan according to the difference between the detected odor concentration and the set threshold, when the difference is large, the rotation speed is maximum, and when the difference is close to the set value, the rotation speed is reduced.
4. The negative pressure fresh air ion deodorization system as recited in claim 1, wherein the control unit comprises a touch display screen for displaying odor concentration.
5. The negative-pressure fresh air ion deodorization system as claimed in any one of claims 1 to 4, wherein the purification unit comprises a filtering unit, an ion deodorization unit and a photo-oxidation unit, and the purification unit is configured as a drawer type structure for sterilization and decomposition of odor polluting molecules such as ammonia gas and hydrogen sulfide.
6. The negative pressure fresh air ion deodorizing system as claimed in claim 5, wherein said blower includes a housing having a cavity, said cavity having a fan blade and a corresponding power device for driving air flow, said cavity having an air outlet and at least one air inlet, said air outlet communicating with said air outlet of said passageway, said air inlet being disposed on a wall of said housing facing said sidewall of said passageway.
7. The negative pressure fresh air ion deodorizing system according to claim 6 wherein said control unit further comprises a remote module, said remote module being connected to a mobile terminal.
8. A negative pressure fresh air ion deodorization method comprises the following steps:
fresh air treatment: fresh air is sucked in through a first fan and then sent into a room through a first purification treatment unit;
a spray deodorization step: the agent is changed into fine mist through a fragrance system and then is sent into a room through a first fan;
and (3) dirty air treatment: the indoor odor is sucked in through a second fan, and odor molecules are decomposed to reach the emission standard through a second purification treatment unit and then are discharged;
odor monitoring step: the control unit controls the operation parameters of the fan and the purification treatment unit according to the detected odor concentration change.
9. The negative pressure fresh air ion deodorization method as claimed in claim 8, wherein the PLC controls the fan to be turned on and operated at a high rotation speed when the odor concentration is equal to or higher than a predetermined threshold value, and controls the fan to be turned off at a low rotation speed or temporarily when the odor concentration is lower than the predetermined threshold value.
10. The negative pressure fresh air ion deodorization method according to claim 9, wherein the set threshold can be changed.
