[0037] First Embodiment
[0038] refer to Figure 1 The first embodiment of this application discloses a toilet deodorizing device 10, which includes an air intake mechanism 11 and a ventilation and drainage assembly 13. The air intake mechanism 11 can be installed on the toilet bowl 21 of the toilet 20. The air intake mechanism 11 may include a fan assembly 111, which can be connected to the toilet bowl 21 through a hollow pipe or other hollow accessories, allowing air to flow between the toilet bowl 21 and the fan assembly 111. The ventilation and drainage assembly 13 is disposed between the toilet drain outlet 20a and the sewage channel 30a, and is connected to the fan assembly 111, meaning air can flow between the ventilation and drainage assembly 13 and the fan assembly 111. The fan assembly 111 may include a motor, which can guide airflow during operation, drawing air from the toilet bowl 21 and guiding the air from the ventilation and drainage assembly 13 into the sewage channel 30a, thereby discharging odors from the toilet bowl 21 to the sewage channel 30a and preventing odors from the toilet 20 from spreading to the bathroom. It is understood that in some embodiments, the suction mechanism 11 may be integrated into the toilet seat of the toilet 20 or other parts of the toilet 20. In such embodiments, the toilet seat or other parts of the toilet 20 with deodorizing function may be regarded as at least part of the toilet deodorizing device 10.
[0039] refer to Figure 2 and Figure 3 The venting and drainage assembly 13 includes a vent connector 131 and an exhaust flange 133. Simultaneously combined with... Figure 4 and Figure 5The vent connector 131 includes a body 1311 and a connector 1313. The body 1311 is approximately cylindrical and has a first channel 131a, which can communicate with the blower assembly 111. Exemplarily, the first channel 131a extends axially along the body 1311. In some embodiments, the body 1311 has external threads, and the body 1311 can pass through a toilet mounting hole 23a of the toilet base 23 (see reference). Figure 1 The external thread is used to fit external nuts and washers to reliably secure the vent connector 131 to the toilet mounting hole 23a. The end of the vent connector 131 opposite to the body 1311 can be installed inside the toilet flange 31 of the toilet 20 (see reference). Figure 1 This reinforces the toilet 20's fixation to the ground or floor. In other embodiments, the body 1311 may have internal threads.
[0040] Of course, the external or internal thread of the main body 1311 is not necessary and can be omitted. For example, the outer side of the main body 1311 can be a smooth cylindrical surface. The main body 1311 can also have other structures for connecting the vent pipe, such as pagoda joints or quick-connect joints.
[0041] refer to Figure 4 The connector 1313 is approximately hollow and block-shaped, protruding from the side of the main body 1311 and including a base 13131 and a reinforcing body 13133 protruding from the edge of the base 13131. The base 13131 has a second channel 131b communicating with the first channel 131a. The second channel 131b is used to connect to the toilet drain pipe 33 (see reference). Figure 1 In the axial direction of the main body 1311, at least a portion of the thickness of the reinforcing body 13133 is less than the thickness of the base body 13131. Further, in some embodiments, the vent connector 131 may have a first direction and a second direction that are perpendicular to each other, the first direction and the second direction being perpendicular to the axial direction of the main body 1311, with the connecting body 1313 protruding from the main body 1311 along the first direction; in the second direction, reinforcing bodies 13133 are respectively protruding from opposite sides of the base body 13131.
[0042] Furthermore, the base 13131 and the reinforcing body 13133 can be arranged in a mirror-symmetric manner with respect to the central plane of the main body 1311, wherein the central plane of the main body 1311 is a plane coplanar with the axis of the main body 1311 and perpendicular to the second direction. Further, in some embodiments, the base 13131 has a larger width than the main body 1311 in the second direction. The base 13131 used to define the second channel 131b can have a relatively uniform wall thickness, and a reinforcing rib 1315 integrally formed with the base 13131 can be provided within the second channel 131b to improve the structural stability of the base 13131 and prevent deformation of the connector 1313 during assembly and use.
[0043] refer to Figure 6 In some embodiments, the reinforcement 13133 extends along a second direction in the width direction of the base 13131. (See reference...) Figure 7 In some embodiments, the reinforcing body 13133 may extend in a straight line and form an angle with the second direction. Of course, in other embodiments, the reinforcing body 13133 may have more variations.
[0044] Continue to refer to Figure 3 and combined Figure 5 The exhaust flange 133 has a drain channel 133a and an exhaust channel 133b. The drain channel 133a is used to connect to the toilet drain outlet 20a, and the exhaust channel 133b is used to guide gas to be discharged into the toilet drain pipe 33. The exhaust channel 133b is used to insert the connector 1313 of the vent connector 131, and the exhaust channel 133b includes a first mounting groove 133b1 and a second mounting groove 133b3 that are interconnected. The second mounting groove 133b3 is located at the edge of the first mounting groove 133b1 in the width direction. In the axial direction of the exhaust flange 133, at least a portion of the flange wall thickness of the exhaust flange 133 at the second mounting groove 133b3 is greater than the flange wall thickness at the first mounting groove 133b1, and the shape of the first mounting groove 133b1 matches the base 13131 of the vent connector 131, while the shape of the second mounting groove 133b3 matches the reinforcement 13133 of the vent connector 131.
[0045] Furthermore, in accordance with the structure in which reinforcing bodies 13133 are respectively protruding on opposite sides of the base 13131, the two sides of the width direction of the first mounting groove 133b1 each have a second mounting groove 133b3. For example, after the vent connector 131 is inserted into the exhaust flange 133, the axis of the body 1311 can be substantially parallel to the axis of the exhaust flange 133, and the second mounting grooves 133b3 are distributed along a second direction on the opposite two edges of the first mounting groove 133b1.
[0046] In the above-mentioned venting and drainage assembly 13, since at least a portion of the flange wall thickness of the exhaust flange 133 at the second mounting groove 133b3 is greater than the flange wall thickness at the first mounting groove 133b1 in the axial direction of the exhaust flange 133, the shape of the first mounting groove 133b1 matches the base 13131 of the venting connector 131, and the shape of the second mounting groove 133b3 matches the reinforcement 13133 of the venting connector 131, the cooperation between the second mounting groove 133b3 and the reinforcement 13133 can better distribute the stress at the connection between the venting connector 131 and the exhaust flange 133, and improve the structural strength of the connection between the two.
[0047] In some embodiments, the base 13131 and the first mounting groove 133b1, and the reinforcing body 13133 and the second mounting groove 133b3, can be fitted with a transition fit to achieve a tight fit between the connecting body 1313 and the exhaust flange 133, preventing air leakage at the connection between the connecting body 1313 and the exhaust flange 133 during the operation of the toilet deodorizing device 10 and preventing the spread of odors. Of course, in other embodiments, the base 13131 and the first mounting groove 133b1, and the reinforcing body 13133 and the second mounting groove 133b3, can be fitted with a clearance fit. This can be achieved by applying a sealing ring or sealing strip to the connecting body 1313, or by coating the connecting body 1313 with sealant, thus preventing air leakage at the connection between the connecting body 1313 and the exhaust flange 133 during the operation of the toilet deodorizing device 10 and preventing the spread of odors.
[0048] refer to Figure 8 and combined Figure 5 The exhaust flange 133 may include a disc body 1331 and an extension 1333 protruding from one side of the disc body 1331, or in other words, the extension 1333 protrudes from one axial side of the disc body 1331. The disc body 1331 is approximately annular, while the extension 1333 may be cylindrical and coaxially arranged with the disc body 1331. The disc body 1331 and the extension 1333 may be integrally formed, for example, by injection molding. In the axial direction of the exhaust flange 133, a drain channel 133a extends from the disc body 1331 to the extension 1333. The disc body 1331 can be used to connect to the toilet drain outlet 20a, and the extension 1333 can be connected to the toilet drain pipe 33, so that sewage can be smoothly discharged from the toilet drain outlet 20a through the drain channel 133a to the toilet drain pipe 33. Of course, in other embodiments, the shapes of the disc body 1331 and the extension 1333 can be adaptively adjusted according to installation requirements.
[0049] The first mounting groove 133b1 and the second mounting groove 133b3 are formed on the circumferential side of the disk body 1331, and the exhaust channel 133b includes an exhaust groove 133b5 communicating with the first mounting groove 133b1 and the second mounting groove 133b3. The exhaust groove 133b5 extends to the side of the extension 1333 opposite to the disk body 1331. Alternatively, the exhaust groove 133b5 extends to the axial side of the extension 1333. Taking the disc body 1331 as an example, the first mounting groove 133b1 and the second mounting groove 133b3 are opened on the outer cylindrical surface of the disc body 1331 and extend towards the drain channel 133a or in other words, along the radial direction of the disc body 1331. The exhaust groove 133b5 extends to the side of the extension 1333 away from the disc body 1331. Alternatively, it can be understood that when the exhaust flange 133 is installed on the toilet drain pipe 33, the exhaust groove 133b5 is located on the side of the disc body 1331 away from the toilet drain outlet 20a.
[0050] Furthermore, in some embodiments, the venting groove 133b5 and the sewage discharge channel 133a are spaced apart to prevent sewage flowing from the toilet drain outlet 20a from easily entering the first mounting groove 133b1 and the second mounting groove 133b3. Combined with Figure 9 The central angle corresponding to the exhaust groove 133b5 is not less than the central angle corresponding to the first mounting groove 133b1, such as... Figure 9 The central angle of the exhaust groove 133b5 shown is 360 degrees, that is, it is arranged around the axis of the sewage channel 133a. In other embodiments, the central angle corresponding to the exhaust groove 133b5 can be 90 degrees, 120 degrees, or 180 degrees, etc.
[0051] by Figure 8 , Figure 9 Taking the illustrated embodiment as an example, the extension 1333 may include an inner ring 13331 and an outer ring 13333 connected to the disk body 1331. The outer ring 13333 surrounds the inner ring 13331 and together with the inner ring 13331 forms an exhaust groove 133b5. The outer ring 13333 and the inner ring 13331 may each be approximately annular and together form an annular exhaust groove 133b5, that is, the central angle of the exhaust groove 133b5 is 360 degrees.
[0052] In embodiments where the central angle of the exhaust groove 133b5 is less than 360 degrees, a recessed groove structure is formed at the position corresponding to the exhaust groove 133b5 to achieve communication with the first mounting groove 133b1 and the second mounting groove 133b3. Other positions can maintain an integrated structure, and there is no need for a clear distinction between the inner ring 13331 and the outer ring 13333.
[0053] exist Figure 8 and Figure 9In the illustrated embodiment, the inner ring 13331 slightly protrudes beyond the outer ring 13333 along the axial direction of the exhaust flange 133. In other embodiments, the inner ring 13331 and the outer ring 13333 may also be flush at their ends away from the disc body 1331. Figure 1 A toilet mounting flange 31 is provided on the toilet drain pipe 33. An exhaust flange 133 can be connected to the toilet mounting flange 31. The toilet mounting flange 31 is fixedly connected to the installation ground. A sealing gasket can be provided between the exhaust flange 133 and the toilet mounting flange 31. A part of the vent connector 13 connected to the exhaust flange 133 can be placed into and snapped into the slot on the toilet mounting flange 31.
[0054] It is understood that the structure of the vent 133b5 is not limited to the structure described above. The extension 1333 on the side opposite to the disc 1331, or the vent flange 133 on the side opposite to the toilet drain outlet 20a, forms a vent 133b5 that communicates with the first mounting groove 133b1 and the second mounting groove 133b3, and the vent 133b5 is isolated from the drain channel 133a. After the vent connector 131 and the vent flange 133 are assembled, the air in the toilet bowl 21 can be guided through the first channel 131a and the second channel 131b of the vent connector 131 and the vent 133b5 of the vent flange 133 into the toilet drain pipe 33, thereby achieving the discharge of odors.
[0055] Of course, the exhaust channel 133b5 can also have other modified structures. (See reference) Figure 10 For example, the vent flange 133 has a sidewall 1335 for defining the drain channel 133a, and the vent flange 133 has a stop portion 1336 connected to the sidewall 1335. The stop portion 1336 is used to prevent sewage from entering the vent channel 133b. Specifically, the vent channel 133b can extend and penetrate the disc body 1331. The vent channel 133b has a stop portion 1336 at a position corresponding to the outlet inside the disc body 1331. The stop portion 1336 can protrude from the sidewall 1335 of the drain channel 133a to prevent sewage from the toilet drain outlet 20a from easily entering the vent channel 133b. Of course, in some modified embodiments, the exhaust channel 133b can extend from the side of the disc body 1331 and penetrate through the extension 1333. The exhaust channel 133b is provided with a stop 1336 at the position corresponding to the outlet inside the extension 1333 to prevent sewage from the toilet drain outlet 20a from easily entering the exhaust channel 133b.
[0056] refer to Figure 11In other embodiments, the exhaust flange 133 has a sidewall 1335 for defining the drain passage 133a. A first mounting groove 133b1 and a second mounting groove 133b3 are formed on the circumferential side of the exhaust flange 133. The exhaust passage 133b extends from the circumferential side of the exhaust flange 133 to the sidewall 1335 and communicates with the drain passage 133a. In other words, in this embodiment, the exhaust passage 133b does not need to be separated from the drain passage 133a of the exhaust flange 133, nor does it need to have a structure similar to a stop 1336. Air in the toilet bowl 21 can flow directly into the drain passage 133a through the first passage 131a, the second passage 131b, and the exhaust passage 133b of the vent connector 131. This structure simplifies the structure of the exhaust passage 133b of the exhaust flange 133, facilitates the processing and forming of the exhaust flange 133, and is one of the applicable solutions.
[0057] Second Embodiment
[0058] refer to Figure 12 The second embodiment of this application discloses a toilet deodorizing device 40, which includes an air intake mechanism 41 and a ventilation and drainage assembly 43. The air intake mechanism 41 can be installed on the toilet bowl 51 of the toilet 50. The air intake mechanism 41 includes a fan assembly 411, which can be connected to the toilet bowl 51 through a hollow pipe or other hollow accessories, allowing air to flow between the toilet bowl 51 and the fan assembly 411. The ventilation and drainage assembly 43 is disposed between the toilet drain outlet 50a and the sewage channel 60a, and is connected to the fan assembly 411, meaning air can flow between the ventilation and drainage assembly 43 and the fan assembly 411. The fan assembly 411 may include a motor, which can guide airflow during operation, drawing air from the toilet bowl 51 and guiding the air from the ventilation and drainage assembly 43 into the sewage channel 60a, thereby discharging odors from the toilet bowl 51 to the sewage channel 60a and preventing odors from the toilet 50 from spreading to the bathroom. It is understood that in some embodiments, the suction mechanism 41 may be integrated into the toilet seat of the toilet 50 or other parts of the toilet 50. In such embodiments, the toilet seat or other parts of the toilet 50 with deodorizing function may be regarded as at least part of the toilet deodorizing device 40.
[0059] The venting and drainage assembly 43 of the second embodiment may also include an exhaust flange 433 and an exhaust connector 435 connected to the exhaust flange 433. Figure 13 and Figure 14 The structure of the exhaust flange 433 can be referred to the description of the first embodiment, which has a drain passage 433a for connecting to the toilet drain outlet 50a and an exhaust passage 433b for exhausting air.
[0060] The exhaust flange 433 may have a structure similar to the first mounting groove 433b1 and the second mounting groove 433b3 in the first embodiment, for inserting the vent connector 435. Combined with... Figure 15 The vent connector 435 has an air passage 435a. One end of the vent pipe 437 is fixedly connected to the vent connector 435 and communicates with the exhaust passage 433b through the air passage 435a. The vent connector 435 includes a main body 4351 and a connecting body 4353 protruding from the main body 4351. The connecting body 4353 includes a base 43531 and a reinforcing body 43533 protruding from the outside of the base 43531. The cross-section of the base 43531 can be approximately racetrack-shaped, and the base 43531 and the reinforcing body 43533 are respectively fixed to the exhaust flange 433. Furthermore, two or more reinforcing bodies 43533 can be provided on opposite sides of the base 43531, or in other words, circumferentially around the base 43531, to improve the structural strength of the connection between the vent connector 435 and the exhaust flange 433.
[0061] Simultaneously combined Figure 16 The first mounting groove 433b1 and the second mounting groove 433b3 are shaped to match the reinforcing body 43533 of the vent connector 435. The flange wall thickness of the exhaust flange 433 corresponding to the reinforcing body 43533 is greater than the flange wall thickness of the exhaust flange 433 corresponding to the base body 43531. This allows the reinforcing body 43533 and the exhaust flange 433 to better distribute the stress at the connection between the vent connector 435 and the exhaust flange 433, thereby improving the structural strength of the connection.
[0062] The cross-section of the reinforcing body 43533 can be referenced in Embodiment 1. Figure 6 and Figure 7 It can protrude from opposite sides of the base 43531 along the width direction of the base 43531, or more than four can be arranged at intervals along the circumference of the base 43531. Of course, in other embodiments, the reinforcing body 43533 can also have more deformations.
[0063] Continue to refer to Figure 15In some embodiments, the connector 4353 has a notch 4353a. The notch 4353a may extend around the outer periphery of the connector 4353 in a complete circle or a portion thereof, or it may extend discontinuously to facilitate cutting and adjustment of the length of the connector 4353. In other words, in this embodiment, the connector 4353 of the vent joint 435 may have a relatively large length at the time of manufacture, but the size of the vent flange 433 can be adapted to different sizes and structural configurations of the toilet 50 and the toilet drain pipe 63, so the length of the vent channel 433b may also vary. By providing the notch 4353a on the connector 4353, the user can be easily guided to adjust the length of the connector 4353, facilitating the assembly 43 of the vent and drain assembly. Of course, in other embodiments, the notch 4353a may only be provided on the reinforcing bodies 43533 on opposite sides of the connector 4353.
[0064] In some embodiments, at least one of the body 4351 and the connector 4353 of the vent 435 is deformable and is used to extend from the bottom of the toilet 50 for connection. For example, see reference... Figure 17 The vent connector 435 has a deformable section 4355, the length of which is not limited. There is space between the bottom of the toilet 50 and the mounting floor 61 for the vent connector 435 to extend. The deformable section 4355 of the deformable vent connector 435 can be stretched, compressed, bent, or otherwise deformed so that the vent connector 435 can extend out from the bottom of the toilet 50. There is no need to cut the toilet 50 itself, which can easily modify the existing toilet 50, improve the convenience of use, and reduce the cost of modifying the toilet 50 for deodorization.
[0065] In particular, in some embodiments, such as the first embodiment Figure 1 The toilet mounting hole 23a shown may have an uncertain position on the toilet base 23. For example, the position of the toilet mounting hole 23a relative to the sewage channel 30a may differ for some toilets. In such cases, the length of the deformable section 4355 can be appropriately lengthened or shortened to match the position of the toilet mounting hole 23a, thereby improving assembly convenience. Of course, for toilets without a toilet mounting hole 23a, the deformable section 4355 can also be lengthened until the air passage 435a is exposed outside the toilet base 23, thus facilitating the installation of the vent pipe 437 and the vent connector 435. A corrugated pipe is one form of this extendable and deformable vent pipe 437.
[0066] Similar to the first embodiment, refer to Figure 14In the second embodiment, the exhaust flange 433 may also include a disc body 4331 and an extension 4333 protruding from one side of the disc body 4331. In the axial direction of the exhaust flange 433, a drain channel 433a extends from the disc body 4331 to the extension 4333. A base 43531 and a reinforcing body 43533 are fixedly connected to the circumferential side of the disc body 4331. The extension 4333 has an exhaust groove 433b5 extending to the side opposite to the disc body 4331, or in other words, the exhaust groove 433b5 extends to the axial side of the extension 4333. The exhaust groove 433b5 communicates with the air passage 435a, and the exhaust groove 433b5 constitutes at least a part of the exhaust passage 433b. The structure of the disc body 4331, the extension 4333, and the exhaust groove 433b5 can be referred to in the first embodiment, and will not be repeated here.
[0067] Similar to the first embodiment, the exhaust groove 433b5 in the second embodiment can also be spaced apart from the drain channel 433a, and the central angle corresponding to the exhaust groove 433b5 is not less than the central angle corresponding to the air passage 435a. Furthermore, the extension 4333 can include an inner ring 43331 and an outer ring 43333 connected to the disc body 4331. The outer ring 43333 surrounds the inner ring 43331 and together with the inner ring 43331 forms the exhaust groove 433b5. In other embodiments, the exhaust channel 433b can extend along the interior of the disc body 4331 to the side wall 4335 of the drain channel 433a, and the drain channel 433a is directly connected (see reference). Figure 11 Alternatively, the side wall 4335 of the sewage channel 433a may be provided with a stop portion 1336 similar to that in the first embodiment (see reference). Figure 10 The details of the exhaust flange 433 will not be repeated here. Other structural details of the exhaust flange 433 can be found in the first embodiment, and will not be repeated here.
[0068] Other detailed structures of the second embodiment can be found in the first embodiment, and will not be repeated here.
[0069] exist Figure 12 In this design, the toilet drain pipe 63 does not have a toilet mounting flange. The vent flange 433 can be directly connected to the toilet drain pipe 63, including but not limited to tight-fitting plug connections, glue connections, or rubber ring sealing connections. For example, combined with... Figure 13 and Figure 14 When the vent flange 433 is directly glued to the toilet drain pipe 63, the outer ring 43333 can protrude from the inner ring 43331 along the axial direction of the vent flange 433. In this connection method, when the inner diameter of the toilet drain pipe 63 is relatively large, the outer ring 43333 can be inserted into the toilet drain pipe 63 and fixedly connected to the mounting floor 61 through the disc body 4331; when the outer diameter of the toilet drain pipe 63 is relatively small, the outer ring 43333 can be sleeved on the outside of the toilet drain pipe 63.
[0070] It is understood that the above-mentioned connection methods can be applied to different application situations in each embodiment. That is, the above-mentioned connection methods are also applicable to the first embodiment and the subsequent third embodiment. In other words, the assembly method of the exhaust flange and the toilet mounting flange in the first embodiment and the third embodiment can be replaced by the assembly method of the exhaust flange 433 and the toilet drain pipe 63 in the second embodiment.
[0071] Third Embodiment
[0072] refer to Figure 18 and Figure 19 This application discloses a toilet deodorizing device 70 in its third embodiment, which includes an air intake mechanism 71 and an exhaust flange 73. The air intake mechanism 71 can be installed on the toilet bowl 81 of the toilet 80. The air intake mechanism 71 includes a fan assembly 711, which can be connected to the toilet bowl 81 through a hollow pipe or other hollow accessories, allowing air to flow between the toilet bowl 81 and the fan assembly 711. The exhaust flange 73 is located between the toilet drain outlet 80a and the sewage channel 90a, and the exhaust flange 73 is connected to the fan assembly 711, meaning air can flow between the exhaust flange 73 and the fan assembly 711. The fan assembly 711 may include a motor, which can guide airflow during operation, drawing air from the toilet bowl 81 and guiding the air from the exhaust flange 73 into the sewage channel 90a, thereby discharging odors from the toilet bowl 81 to the sewage channel 90a and preventing odors from the toilet 80 from spreading to the bathroom. It is understood that in some embodiments, the suction mechanism 71 may be integrated into the toilet seat or other parts of the toilet 80. In such embodiments, the toilet seat or other parts with deodorizing function may be regarded as at least part of the toilet deodorizing device 70.
[0073] The difference from the second embodiment is that the exhaust flange 73 of the third embodiment includes an integrally formed body 731 and a pipe connector 733. The body 731 has a drain channel 73a for connecting to the toilet drain outlet 80a. The exhaust flange 73 also has an exhaust channel 73b, which extends from the pipe connector 733 to the body 731 and is used to guide gas to be discharged into the toilet drain pipe 90. The fan assembly 711 of the toilet deodorizing device 70 and the pipe connector 733 of the exhaust flange 73 can be connected through a vent pipe 75 to guide air from the toilet bowl 81 into the sewage channel 90a from the exhaust flange 73. The arrangement of the exhaust channel 73b in the body 731 can refer to the first and second embodiments, and will not be repeated here.
[0074] In this embodiment, since the pipe connector 733 is integrally formed with the body 731, the connection between the body 731 and the pipe connector 733 not only simplifies the connection structure compared to the assembly and fixing methods of the first and second embodiments, but also ensures the structural strength of the connection. For example, it is easier to add reinforcing ribs to the connection between the body 731 and the pipe connector 733, thus making it easier to improve the structural strength of the connection. Moreover, since the pipe connector 733 is integrally formed with the body 731, the exhaust channel 73b can have a larger internal dimension at the connection position between the pipe connector 733 and the body 731, and its interior is also easier to be formed into a smooth transition surface to reduce air resistance, thereby facilitating the entry of air from the toilet bowl 81 into the sewage channel 90a through the exhaust flange 73.
[0075] refer to Figure 20 Similar to the first embodiment, the body 731 may include a disc 7311 and an extension 7313 protruding from one axial side of the disc 7311. In the axial direction of the body 731, a drain channel 73a extends from the disc 7311 to the extension 7313, and a pipe connector 733 protrudes from the circumferential side of the disc 7311. The pipe connector 733 has a first channel 73b1, and the body 731 has an exhaust groove 73b2. The first channel 73b1 communicates with the exhaust groove 73b2, and the first channel 73b1 and the exhaust groove 73b2 together constitute at least a portion of the exhaust channel 73b.
[0076] Similar to the first embodiment, the exhaust groove 73b2 can extend along the interior of the disc body 7311 to one axial side of the extension portion 7313, or in other words, the exhaust groove 73b2 extends along the interior of the disc body 7311 to the side opposite to the disc body 7311, which will not be described in detail here. The first channel 73b1 extends along the interior of the pipe connector 733. The axial direction of the pipe connector 733 can be substantially parallel to the axial direction of the body 731, or it can be set at an angle to the axial direction of the body 731. The pipe connector 733 is used to connect the vent pipe 75 so that the first channel 73b1 is connected to the fan assembly 711, and the exhaust groove 73b2 is then connected to the fan assembly 711 through the first channel 73b1, which will not be described in detail here.
[0077] Continue to refer to Figure 20 Similar to the first embodiment, the venting channel 73b2 and the sewage discharge channel 73a are spaced apart to prevent sewage flowing from the toilet drain outlet 80a from easily entering the venting channel 73b. (Reference) Figure 21In other embodiments, the body 731 has a sidewall 7315 for defining the drain channel 73a, and the body 731 has a stop portion 7316 connected to the sidewall 7315, the stop portion 7316 for preventing sewage from entering the vent channel 73b. Specifically, the vent channel 73b can extend and penetrate the disc body 7311, and the vent channel 73b has a stop portion 7316 at a position corresponding to the outlet inside the disc body 7311. The stop portion 7316 can protrude from the sidewall 7315 of the drain channel 73a, thus preventing sewage from the toilet drain outlet 80a from easily entering the vent channel 73b. Of course, in some modified embodiments, the vent channel 73b can extend laterally or radially from the disc body 7311 and penetrate the extension portion 7313, and the vent channel 73b has a stop portion 7316 at a position corresponding to the outlet inside the extension portion 7313, thus preventing sewage from the toilet from easily entering the vent channel 73b.
[0078] refer to Figure 22 In other embodiments, the body 731 has a sidewall 7315 for defining the drain passage 73a, and the exhaust passage 73b extends laterally or radially from the disc body 7311 to the sidewall 7315 and communicates with the drain passage 73a. In other words, in this embodiment, the exhaust passage 73b does not need to be separated from the drain passage 73a of the exhaust flange 73, nor does it need to have a structure similar to a stop 7316. Air in the toilet bowl 81 can flow directly into the drain passage 73a through the first passage 73b1 of the pipe connector 733 and the exhaust groove 73b2 of the body 731. This structure simplifies the structure of the exhaust passage 73b of the exhaust flange and facilitates the processing and forming of the exhaust flange.
[0079] refer to Figure 23 In the third embodiment, the pipe connector 733 may also have a deformable section 7331 for extending from the bottom of the toilet 80 for connection. The length of the deformable section 7331 is not limited. There is space between the bottom of the toilet 80 and the mounting floor 91 for the pipe connector 733 to extend. The deformable section 7331 of the deformable pipe connector 733 can be stretched, compressed, bent, or otherwise deformed so that the pipe connector 733 can extend from the bottom of the toilet 80. This eliminates the need for cutting the toilet 80 itself, allowing for convenient modification of existing toilets 80, improving usability, and reducing the cost of modifying the toilet 80 for deodorization. The detailed structure of the deformable section 7331 can be found in the second embodiment and will not be repeated here.
[0080] Although the present invention has been described and illustrated with reference to preferred embodiments and several alternatives, it is not limited to the specific descriptions contained herein. Other alternative or equivalent components may also be used to practice the present invention.
