CROSS REFERENCE TO RELATED PATENT APPLICATION [0001] This patent application is based on a U.S. provisional patent application No. 60/549,892 filed Mar. 1, 2004. FIELD OF THE INVENTION [0002] The present invention relates to a deodorizing system, and more particularly to a deodorizing system for ventilating bad odor generated from the odor generating sources in a bathroom. BACKGROUND OF THE INVENTION [0003] The poor air quality of toilets has already been taken for granted, especially for frequently used public toilets. In order to dilute the toilet odor, many ventilation mechanisms were developed. Referring to FIG. 1, a ventilated toilet with an air duct is disclosed in, for example, Taiwanese Patent Publication No. 00205832, entitled "Toilet Exhaust Device", and the contents of which are hereby incorporated for reference. As shown in FIG. 1, the ventilated toilet 1 includes an air duct 10 around the bowl rim thereof for exhausting the toilet odor therethrough. [0004] Referring to FIG. 2, a schematic layout view of a conventional deodorizing system disclosed in Japanese Patent Application No. JP 03-199538 is illustrated. As shown in FIG. 2, the deodorizing system includes several ducts 31, 35, 29 and 33 for exhausting the bad odor generated from several odor generating sources such as a toilet bowl 9 for urine, a deodorizing port 27, a toilet bowl 17 and a washing stand unit 21, respectively. The ducts 31, 29, 33 and 35 are connected to a ventilation duct 37. The negative pressure of the deodorizing system is established by a ventilating fan 39, which is installed in the downstream of the ventilation duct 37. As known, the ventilation volume per unit time is dependent on the length, type or diameter of the duct and the distance between respective odor generating source and the ventilating fan 39. For controlling the ventilation volume per unit time of each odor generating source, adjusting valves 41, 47, 43 and 45 are installed between the ducts 31, 35, 29 and 33 and the odor generating sources 9, 27, 17 and 21, respectively. By using the adjusting valves to control the ventilation volume per unit time within an acceptable value, each odor generating source has sufficient suction and deodorizing capacity. In addition, the bad odor generated from one source will not be exhausted from any other odor generating source. As shown in FIG. 2, the odor generating sources 9, 27 are relatively farther than the odor generating sources 17 and 21 from the ventilating fan 39. Consequently, the openings of the adjusting valves 41 and 47 should be larger than those of the adjusting valves 43 and 45. [0005] Referring to FIG. 3, a schematic layout view of another conventional deodorizing system used in a house having two bathrooms is illustrated. One bathroom includes several odor generating sources such as a toilet bowl 8 for urine, a deodorizing port 26, a toilet bowl 16 and a washing stand unit 20. The ducts connected with these odor generating sources 8, 26, 16 and 20 are connected to a ventilation duct 5. The odor generating sources of the other bathroom includes a toilet bowl 9 for urine, a deodorizing port 27, a toilet bowl 17 and a washing stand unit 21. The ducts connected with these odor generating sources 9, 27, 17 and 21 are connected to another ventilation duct. The negative pressure of the deodorizing system is established by a ventilating fan 39, which is installed in the downstream of the ventilation ducts. Likewise, adjusting valves 40, 46, 42, 44, 41, 47, 43 and 45 are installed to the proximate odor generating sources 8, 26, 16, 20, 9, 27, 17 and 21, respectively, in order to control the ventilation amount of the bad odor. [0006] Unfortunately, it is difficult to adjust the flow rate or the static pressure of the odor in each conduit. For example, the low pressure conduit can withstand a pressure range of from -500 Pa to +500 Pa, the medium pressure conduit can withstand a pressure range of from -1000 Pa to +750 Pa, and the high pressure conduit can withstand a pressure range of from -750 Pa to +2000 Pa. Since the toilet bowl 8 and the deodorizing port 26 is very distant from the ventilating fan 39 and the length of the duct 5 is very long, the static pressures thereof are possibly lower than the operative ranges of the corresponding adjusting valves 40 and 46. In contrast, since the washing stand unit 21 is very close to the ventilating fan 39, the static pressure thereof readily exceeds the operative range of the adjusting valve 45. Therefore, some of the adjusting valves are ineffective for controlling ventilation amount. Due to the above problems, the expansibility of the layout configuration is limited. SUMMARY OF THE INVENTION [0007] The present invention is to provide a deodorizing system for ventilating bad odor generated from the odor generating sources in a bathroom, in which the flow rate or the static pressure of the odor in each conduit are controllable. [0008] In accordance with an aspect of the present invention, there is provided a deodorizing system. The deodorizing system includes a first main conduit, a suction generating device, a first terminal conduit, a first odor generating source, a second terminal conduit, a second odor generating source and a first adjusting damper. The suction generating device is disposed in the downstream of the first main conduit. The first terminal conduit is connected to the first main conduit by a first junction. The first odor generating source is connected to the first terminal conduit. The second terminal conduit is connected to the first main conduit by a second junction. The second odor generating source is connected to the second terminal conduit. The first adjusting damper is positioned in the first main conduit between the first junction and the second junction for regulating the airflow ratio of the first odor generating source to the second odor generating source. [0009] In an embodiment, the deodorizing system further comprises a second adjusting damper and a third adjusting damper. The second adjusting damper is positioned in the first terminal conduit proximate to the first odor generating source. The third adjusting damper is positioned in the second terminal conduit proximate to the second odor generating source. [0010] In an embodiment, the first, second and third adjusting dampers are adjusting valves having adjusting varied opening area for regulating the ventilation amounts in the first main conduit, the first terminal conduit and the second terminal conduit. [0011] In an embodiment, the adjusting valves are ball valves, gate valves or butterfly valves. [0012] In an embodiment, the suction generating device is a ventilating fan or a pump, and a check valve is disposed in the downstream of the suction generating device for preventing backflow. [0013] In an embodiment, the deodorizing system further comprises a second main conduit connected to the first main conduit by a third junction proximate to the suction generating device, a third terminal conduit connected to the second main conduit by a fourth junction, and a third odor generating source connected to the third terminal conduit. [0014] In an embodiment, the deodorizing system further comprises a fourth adjusting damper positioned in the second main conduit for regulating the ventilation amounts in the second main conduit.
