Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

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.

2. Description of the Prior Art

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.

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

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.

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

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.

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.

The toilet deodorizing apparatus of the present invention comprises the following elements:

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.

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.

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.

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.

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.

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.

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.
