Description

Technical Field

[0001] The present invention relates to a toilet assembly, and more particularly to a toilet deodorizing device, which includes an exhaust assembly capable of guiding the odor around the toilet area to be discharged through an existing sewage channel. Background Art

[0002] Odors from using a traditional toilet are often combated by releasing fragrance into the restroom. Restrooms may also be equipped with some type of ventilation designed to provide ventilation to the restroom space. A ventilation fan may be installed in the restroom ceiling or window to draw air out of the restroom.

[0003] These traditional methods of eliminating restroom odors often fail to provide satisfactory results. For example, the undesirable odor may have spread throughout the restroom space before being discharged. Users using the restroom will still experience the bad odor when using the toilet.

[0004] Additionally, ventilation equipment designed to remove odors from toilets may not have a suitable location to remove the odors. For example, in a restroom without windows, the odors can only be vented to the attic. However, the odors in the attic can enter other spaces in the same building, and the odors may affect not only the restroom, but also other parts of the building.

[0005] Therefore, it is necessary to develop a toilet deodorizing device that can effectively discharge odor from the toilet without allowing the odor to spread into the restroom or other parts of the building. Summary of the invention

[0006] Certain variations of the present invention provide a toilet deodorizing device including an exhaust assembly that is capable of directing odorous gases around the toilet area to be discharged through an existing sewage channel.

[0007] Certain variations of the present invention provide a toilet deodorizing device including an exhaust assembly that is capable of effectively drawing odors from the toilet and exhausting them without allowing the odors to spread into the restroom or other parts of the building.

[0008] In one aspect of the present invention, there is provided a toilet deodorizing device for a toilet assembly, the toilet assembly comprising a toilet having an upper rim portion and a lower connecting portion, a toilet mounting flange connected to a sewage channel, the toilet deodorizing device comprising:

[0009] a main body shell having an air inlet and an air outlet;

[0010] A gas suction assembly includes a gas suction port device and a gas suction pipe. A gas suction port device is supported on the toilet, and the gas suction port device is communicated with the air inlet of the main body shell through the gas suction pipe;

[0011] an air intake fan mounted in the main housing; and

[0012] An air discharge assembly defines an air discharge passage extending from the exhaust port of the main body housing to the sewage passage below the toilet. The air discharge assembly includes an exhaust pipe forming part of the air discharge passage and extending from the exhaust port to the sewage passage through the lower connecting portion of the toilet. When the suction fan is turned on, air is sucked from the upper edge of the toilet and discharged into the sewage passage through the air discharge assembly, thereby minimizing the odor spreading from the toilet.

[0013] The above summary is intended only to introduce certain concepts and is not intended to identify any key or essential features of the claimed subject matter. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] refer to Figures 1 to 8 A preferred embodiment of the present invention shows a toilet deodorizing device. Broadly speaking, the toilet deodorizing device may include a main body shell 10 having an air inlet 11 and an air outlet 12, an air suction port device 40, an air suction fan 20, and an air discharge assembly 30. The toilet deodorizing device may be used for a toilet assembly 100 including a toilet 101 having an upper edge portion 102 and a lower connecting portion 103, and a toilet mounting flange 104 connected to a sewage channel 300. The toilet deodorizing device of the present invention can guide the odor from the toilet 101 to be discharged to the sewage channel 300 so that the odor does not spread to other parts of the bathroom or other parts of the building.

[0028] The air intake fan 20 may be installed in the main body housing 10 to inhale air from the air intake port device 40 .

[0029] The air discharge assembly 30 may be defined as an air discharge passage 31 extending from the air outlet 12 to the sewage passage 300. The air discharge assembly 30 may include an exhaust pipe 32 forming part of the air discharge passage 31 and connected from the air outlet 12 to the sewage passage 300 through the lower connection portion 103 of the toilet 101, so that when the suction fan 20 is turned on, air is sucked from the upper edge portion 102 of the toilet 101 and discharged into the sewage passage 300 through the air discharge assembly 30, thereby minimizing the odor diffused from the toilet 101.

[0030] According to a preferred embodiment of the present invention, the toilet deodorizing device of the present invention can be used in an existing toilet 101, which can be securely mounted on the sewage channel 300 through a toilet mounting flange 104 having an opening 1041. Those skilled in the art will appreciate that the toilet 101, the sewage channel 300 and the toilet mounting flange 104 do not constitute a part of the present invention.

[0031] refer to Figure 1 , the main body housing 10 can be installed near the water tank 105 of the toilet 101. The water tank 105 can be located on the top of the toilet 101, wherein the main body housing 10 can be installed on the side of the water tank 105. As an alternative, the main body housing 10 can be installed on any side of the water tank 105, and can even be installed on the wall or floor of the bathroom instead of being installed near the water tank 105.

[0032] The suction fan 20 may be installed in the main body housing 10 for sucking gas from the gas suction port device 40 and through the air inlet 11. The gas suction port device 40 may be supported on the upper edge portion 102 of the toilet 101, or built into the toilet seat 105. In this preferred embodiment, the toilet deodorizing device may further include a gas suction pipe 41 extending between the air inlet 11 and the gas suction port device 40, wherein the air near the upper edge portion 102 of the toilet 101 may be sucked into the main body housing 10 through the gas suction pipe 41.

[0033] The gas suction port device 40 may provide an opening 401 for communicating with the gas suction pipe 41. Figure 1 As shown, the gas suction port device 40 can be installed on the upper edge portion 102 of the toilet 101. In this preferred embodiment, the gas suction port device 40 can include a gas suction pipe 41 supported on the upper edge portion 102 of the toilet 101, wherein the opening 401 can be set in the gas suction port device 40.

[0034] The toilet deodorizing device may further include a control circuit 50 and a power supply 51, which are mounted in the main body housing 10 and are electrically connected to the suction fan 20 for controlling the operation thereof.

[0035] It should be noted that the air discharge channel 31 of the air discharge component 30 mentioned above can be composed of several sections of channels formed by different components. When these components are connected together in the manner described below, the air discharge channel 31 can be fully defined. This configuration can be Figure 6 Shown in.

[0036] Therefore, the exhaust duct 32 may be connected to the exhaust port 12 of the main body housing 10 , and a first passage 311 may be defined in the exhaust duct 32 to allow air to pass therethrough. The first passage 311 may constitute at least a portion of the air discharge passage 31 .

[0037] The connector 34 may define a second channel 312, which may be configured as a through channel formed within the connector 34. Figure 5 As shown, the longitudinal portion 341 and the transverse portion 342 may be hollow structures, wherein the second channel 312 may pass through the longitudinal portion 341 and the transverse portion 342. One end of the second channel 312 may communicate with the first channel 311, and the other end of the second channel 312 may communicate with the third channel 313.

[0038] In addition, the air discharge assembly 30 may further include an air guide 33 mounted at the lower portion of the toilet 101 for connecting with the exhaust pipe 32. The air guide 33 may be mounted on the toilet mounting flange 104 of the toilet assembly 100 so as to be firmly supported at the lower portion of the toilet 101. According to a preferred embodiment, the air guide 33 may be configured to have an annular structure, such as Figure 3 and Figure 4 As shown. Therefore, the air guide 33 may have an upper annular portion 331 and a lower annular portion 332, wherein the outer diameter of the upper annular portion 331 is greater than the outer diameter of the lower annular portion 332. The air guide 33 may also define a third channel 313, which may be configured as a through hole formed on the upper annular portion 331 of the air guide 33. More specifically, the third channel 313 may be a channel extending from an opening of the outer side surface 3311 of the air guide to an opening of the bottom surface 3312 of the air guide. The air guide 33 may be configured such that the third channel 313 may be directly connected to the flange through hole 1041 of the toilet mounting flange 104. In this case, air may pass from the second channel 312 through the third channel 313 and the opening 1041, and finally be discharged to the sewage channel 300.

[0039] In addition, the air guide 33 may further define a fourth channel 314, which may be configured as an open channel formed in the air guide 33 and extending through the annular center thereof. The fourth channel 314 may be directly connected to the sewage channel 300, or may be connected to the sewage channel 300 through the flange through hole 1041 of the toilet mounting flange 104. The third channel 313 may be connected to the fourth channel 314. Depending on the situation in which the present invention is applied, only the third channel 313 or the third channel 313 and the fourth channel 314 together may constitute the air discharge channel 31. In this preferred embodiment, the air discharge channel 31 may be composed of the first to third channels 311, 312, 313.

[0040] In addition, the air discharge assembly 30 may further include a connecting member 34 that connects the exhaust pipe 32 and the air guide 33. Figure 3 As shown, the connector 34 may have a longitudinal portion 341 and a transverse portion 342 extending transversely from the longitudinal portion 341. Each of the longitudinal portion 341 and the transverse portion 342 may be configured to have a tubular hollow structure. The outer surface of the longitudinal portion 341 may be threaded to allow easy fixing to the toilet assembly 100 by a simple thread mechanism.

[0041] Therefore, the longitudinal portion 341 of the connecting member 34 can be connected to the exhaust pipe 32, and the transverse portion 342 of the connecting member 34 can be connected to the upper annular portion 331 of the air guide 33. In summary, the first to third passages 311, 312, 313 can be combined to form an air discharge passage 31 for discharging the sucked odor-containing air into the sewage passage 300. This air discharge passage 31 can form a path to guide and discharge the odor-containing air around the toilet 101 into the sewage passage 300 without returning to the bathroom or other parts of the building. This configuration can be used in Figure 6 Graphical display in.

[0042] From the foregoing description, those skilled in the art will appreciate that due to different configurations of the existing toilet assembly 100, such as a wall-mounted toilet or a toilet without a toilet mounting flange, there may be the following alternative embodiments.

[0043] For example, Figure 3 As shown, when the lower connection part 103 of the toilet 101 has a mounting hole 1031, the longitudinal portion 341 of the connection member 34 can pass through and be connected to the mounting hole 1031 of the lower connection part 103, and the transverse portion 342 can be connected to the upper annular portion 331 of the air guide 33. In this case, the exhaust pipe 32 can be connected to the upper end 3411 of the longitudinal portion 341 of the connection member 34. Then, the air in the exhaust pipe 32 can be guided through the second channel 312 to reach the third channel 313.

[0044] In another example, Figure 7 As shown, when the lower connection part 103 of the toilet 101 does not have the mounting hole 1031, the connection member 34 can be omitted, and the exhaust pipe 32 can pass through the opening of the lower connection part 103 or the wall behind the wall-mounted toilet and be directly connected to the upper annular part 331 of the air guide 33. In this case, the first channel 311 can be directly connected to the third channel 313, so that the air discharge channel 31 is composed of the first channel 311 and the third channel 313.

[0045] In another alternative embodiment, Fig. 9 As shown, the air guide 33 may be configured to be connected by a third channel 313 and a fourth channel 314. In this case, the air may pass through the third channel 313 and the fourth channel 314 from the second channel 312, and finally be discharged into the sewage channel 300. Therefore, the air discharge channel 31 may be composed of the first channel 311, the second channel 312, the third channel 313 and the fourth channel 314. In particular, the third channel 313 may be formed by extending from an opening of the outer side surface 3311 of the air guide 33 to another opening of the inner side surface 3313 of the air guide 33, and finally communicate with the fourth channel 314 that runs through the annular center of the air guide 31.

[0046] The operation of the present invention is as follows: when the suction fan 20 is turned on, the gas containing odor around the upper edge portion 102 of the toilet 101 can be sucked into the main body housing 10 through the gas suction pipe 41. Then, the air can be guided into the exhaust pipe 32 and finally reach the sewage channel 300 through the air discharge channel 31. Therefore, the odor around the upper edge portion 102 of the toilet 101 can be finally discharged through the sewage channel 300, and the odor can be prevented from spreading to the bathroom or other parts of the building.

[0047] It is worth mentioning that, according to the situation in which the present invention is used, the air discharge channel 31 can be composed of different components. Some variations have been mentioned above. Therefore, the toilet deodorizing device of the present invention can be adapted to toilet components 100 of different structures.

[0048] Although the present invention has been illustrated and described in the form of a preferred embodiment and several alternatives, it is not limited to the specific description contained in this specification. The present invention can also be practiced using other alternative or equivalent components.
