Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a toilet deodorizing apparatus, and more particularly to a main body controlled by a switch of a control unit to guide smell gases to the inside from a gas inlet and then guided to the outside through a gas outlet. 
         [0003]    2. Description of the Prior Art 
         [0004]    At present, most toilet deodorizing apparatuses available in the market adopt a design of putting chemicals into the toilet or a design of diluting the concentration of smell odors. However, these conventional apparatuses fail to meet the healthy, safety and environmental protection requirements or take the practicality and commercial cost-effectiveness into consideration. 
         [0005]    The aforementioned conventional toilet deodorizing apparatus has the following drawbacks:
   1. Solid, liquid and gas chemicals are harmful to our health.   2. Chemical deodorants may damage our water resources and environments.   3. The installation of an additional small bubble generator incurs a higher cost and a more complicated structure.   4. The smell small air bubble has a low solubility, and thus the bad smell may still disperse into the air.   
 
       SUMMARY OF THE INVENTION 
       [0010]    Therefore, it is a primary objective of the present invention to provide a toilet deodorizing apparatus to overcome the problems of the conventional toilet deodorizing apparatus with components that can only eliminate or reduce the smell without any practical added-on value of improving the health safety, environmental protection and deodorizing functions. 
         [0011]    To achieve the aforementioned objective and function, the present invention provides a toilet deodorizing apparatus having a main body controlled by a sensor switch of a control unit for discharging gases. Smell gases are guided to the inside from a gas inlet of the main body and then guided to the outside through a gas outlet to achieve the deodorizing effect.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0017]    The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention. 
         [0018]    With reference to  FIGS. 1 and 2 , a preferred embodiment of the present invention is applied between a toilet  1  and a water tank  2 . The toilet  1  includes an internal sink space  11 , a water outlet pipe  12 , a plurality of water outlet holes  13 , a first channel  14 , a second channel  15  and a sewer pipe  16 , wherein the water outlet pipe  12  is interconnected to the plurality of water outlet holes  13  and the first channel  14 , and the internal sink space  11  is interconnected to the sewer pipe  16 , and the second channel  15  is interconnected to the sewer pipe  16 . The water tank  2  is disposed above the toilet  1  and interconnected to the water outlet pipe  12  of toilet  1 . 
         [0019]    The toilet deodorizing apparatus of the present invention comprises the following elements: 
         [0020]    A main body  3  is disposed below the water tank  2  and has a gas inlet  31  and a gas outlet  32 , wherein the gas outlet  32  is coupled to the second channel  15 , and the gas outlet  32  of the main body  3  is pivotally coupled to a one-way gate  321  as shown in  FIG. 4 , and an exhaust pipe  322  is installed between the gas outlet  32  and the second channel  15 . 
         [0021]    A control unit  40  is installed at a predetermined position inside the main body and includes a motor  41 , a blower  42  and a sensor  43 , wherein the sensor  43  is provided for controlling switches of turning on or off the motor  41  and the blower  42 , and the motor  41  and the blower  42  are installed at opposite positions of the main body  3 . 
         [0022]    A valve  141  is pivotally installed between the water outlet pipe  12  of the water tank  2  and the first channel  14  of the toilet  1 , and the second channel  15  of the toilet  1  has a insect screen  151 , and the main body  3  is covered by a housing  21  extended from the bottom of the water tank  2 , and the first channel  14  is interconnected to the housing  21 . The sensor  43  of the control unit  40  is an infrared sensor for sensing a human body, wherein the motor  41  and the blower  42  are turned on when the infrared sensor  43  senses a human body. The sensor  43  of the control unit  40  also can be a body weight sensor, wherein the motor  41  and the blower  42  are turned on when a body weight presses onto a toilet seat, or the motor  41  and the blower  42  are turned off when the body weight is released from the toilet seat. 
         [0023]    With reference to  FIG. 2  for a schematic view of eliminating a bad smell by suction in accordance with a preferred embodiment of the present invention, while water in the water tank  2  is not being used for flushing the toilet, the water outlet pipe  12  and the plurality of water outlet holes  13  are interconnected to the internal sink space  11  of toilet  1 , and the water outlet pipe  12  is an empty pipe. When airflow is sucked into the gas inlet  31  of the main body  3  inside the housing  21 , the pressure is changed to draw the smell gas from the internal sink space  11  of the toilet  1  through the first channel  14 . Now, the valve  141  droops automatically into an open status and blocks the water outlet pipe  12  and draws the smell gas into the housing  21 , The smell gas is then guided to the inside from the gas inlet  31  of the main body  3 , and guided to the outside from the gas outlet  32  and one-way gate  321  (as shown in  FIG. 5 ) and finally the smell gas is discharged from the exhaust pipe  322  into the second channel  15  through the insect screen  151  and entered into the sewer pipe  16 . 
         [0024]    Since the channels are sealed by the static water between the internal sink space  11  of the toilet  1  and the sewer pipe  16 , therefore the water discharged into the sewer pipe  16  is blocked by the static water without producing smell gas or overflowing to the outside of the internal sink space  11 , so as to improve the deodorizing effect significantly, and the insect screen  151  installed between the second channel  15  and the exhaust pipe  322  can prevent unknown living organisms inside the sewer pipe  16  from entering into the indoor space through the exhaust pipe  322 , so as to provide a pest control effect. 
         [0025]    With reference to  FIG. 3  for a schematic view of a suction and flushing status of a preferred embodiment of the present invention after the suction stops, when the toilet  1  is flushed, water flows from the water outlet pipe  12  to open the originally closed valve  141  by the flushing force. Now, the valve  141  is in a horizontal status to block the first channel  14  and prevent water to enter, and water flows through the plurality of water outlet holes  13  into the internal sink space  11 , and now the water outlet pipe  12  is filled up with water, and the main body  3  stops operating. After the flushing ends, the suction and deodorizing operation takes place again as shown in  FIG. 2 . 
         [0026]    While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
