As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0030] First embodiment:

[0031] Referring to Figures 1 and 2, a first embodiment of this application discloses a toilet deodorizing device 10, which includes an air intake 11, an air intake mechanism 13, and a ventilation and drainage assembly 15. The air intake 11 includes a mounting portion 111 and an extension portion 113 connected to the mounting portion 111. The mounting portion 111 is disposed on the top edge of the toilet bowl 21. Part or all of the extension portion 113 extends into the interior of the toilet bowl 21, including extending into the recessed toilet bowl 21a of the toilet bowl 21 (refer to Figures 1 and 3) or extending into the center of the upper opening 21a1 of the toilet bowl 21 (refer to Figure 4). The extension portion 113 is a hollow structure and has an air intake 113a. Exemplarily, when a basically horizontal geometric plane is tangent to the top edge of the toilet bowl 21, the air intake 113a of the extension portion 113 can be entirely located below the geometric plane, or it can be partially located below the geometric plane. The mounting section 111 has a hollow structure and an internal ventilation channel 111a that communicates with the air intake 113a for airflow. The air intake mechanism 13 includes a fan assembly 131 that connects to the ventilation channel 111a and the air intake 113a. The ventilation and drainage assembly 15 is located between the toilet drain outlet 21b and the sewage channel 30a. The ventilation and drainage assembly 15 is connected to the fan assembly 131, meaning that air can flow between the ventilation and drainage assembly 15 and the fan assembly 131. The fan assembly 131 may include a motor and an impeller linked to the motor's output shaft, which guides airflow during operation. The fan assembly 131 can draw in air through the air intake 113a and guide the air from the ventilation and drainage assembly 15 into the sewage channel 30a, thereby discharging odors from the toilet bowl 21 into the sewage channel 30a and preventing odors from the toilet 20 from spreading into the bathroom.

[0032] Referring to Figures 1 and 2, in some embodiments, the suction component 11 is in the shape of a hollow plate, and the mounting portion 111 is used to assemble to the top edge of the toilet bowl 21 to facilitate the assembly and fixation of the suction component 11 and the toilet 20. The extension portion 113 and the mounting portion 111 can be integrally formed to improve the forming efficiency of the suction component 11. Of course, in other embodiments, the extension portion 113 can also be assembled and fixed to the mounting portion 111, for example, by means of threaded connection or snap-fit, and to achieve a detachable connection between the extension portion 113 and the mounting portion 111, so as to facilitate the user to remove the extension portion 113 for cleaning or replacement.

[0033] The mounting portion 111 may have mounting holes 111b for fixing the suction component 11 and for fitting the toilet seat mounting hole 21c. The mounting holes 111b may have a relatively large diameter to match toilet seats of different sizes. For example, in the embodiment shown in FIG1, two mounting holes 111b are provided at intervals along the length extension direction of the mounting portion 111, and the two mounting holes 111b correspond one-to-one with the toilet seat mounting holes 21c on the toilet bowl 21, thereby enabling convenient assembly of the suction component 11 with the toilet bowl 21 and the toilet seat.

[0034] Furthermore, the suction component 11 may include an adjusting plate 115 connected to the mounting portion 111, the adjusting plate 115 being movably disposed within the mounting hole 111b. In some embodiments, the mounting hole 111b is circular, rectangular, or racetrack-shaped, thereby adapting to toilet seat mounting holes 21c with different spacing and positions, improving the versatility of the suction component 11. The adjusting plate 115 matches the mounting hole 111b and has a mounting groove 115a with a length greater than the diameter of the toilet seat mounting hole 21c. After the adjusting plate 115 is fitted into the mounting hole 111b, the adjusting plate 115 can rotate relative to the mounting portion 111 within the mounting hole 111b to change the relative position of the mounting groove 115a and the mounting hole 111b, so that the mounting groove 115a and the toilet seat mounting hole 21c can be aligned, thereby using fasteners such as bolts to assemble and fix the toilet seat to the toilet seat mounting hole 21c of the toilet bowl 21.

[0035] Furthermore, in some embodiments, after the adjusting piece 115 is fitted into the mounting hole 111b, its upper end face does not protrude from the upper end face of the mounting part 111. For example, the upper end face of the adjusting piece 115 can be flush with the upper end face of the mounting part 111, or recessed downward relative to the upper end face of the mounting part 111, so as to improve the structural compactness of the suction member 11 and prevent the thickness of the suction member 11 from increasing too much, causing the height of the toilet seat relative to the top edge of the toilet bowl 21 to increase too much and affecting the comfort of use.

[0036] In other embodiments, the suction component 11 can have further variations. For example, a specially designed toilet seat 23, as shown in Figure 3 or Figure 4, can be used to replace the suction component 11 shown in Figures 1 and 2. In this case, the suction component 11 and the toilet seat 23 can be considered integrated into one piece, thereby reducing the number of parts and improving the compactness of the structure. These variations should be considered as equivalent alternatives to the suction component 11 of this application and should not be excluded from the protection scope of this application. They will not be listed one by one.

[0037] The toilet deodorizing device 10 includes an air intake 11, an air intake mechanism 13, and a ventilation and drainage assembly 15. The air intake 11 includes a mounting portion 111 and an extension portion 113 connected to the mounting portion 111. The mounting portion 111 is located on the top edge of the toilet bowl 21, and the extension portion 113 extends into the toilet bowl 21. The extension portion 113 is hollow and has an air intake port 113a. The mounting portion 111 is hollow and has an internal ventilation channel 111a that communicates with the air intake port 113a to allow airflow. The air intake mechanism 13 includes a fan assembly 131 that communicates with the ventilation channel 111a and the air intake port 113a. The ventilation and drainage assembly 15 is located between the toilet drain outlet 21b and the sewage channel 30a, and is connected to the fan assembly 131. The fan assembly 131 can draw in air through the air intake 113a and guide the air from the venting and draining assembly 15 into the sewage channel 30a, thereby discharging the odor in the toilet bowl 21 to the sewage channel 30a and preventing the odor in the toilet 20 from spreading to the bathroom.

[0038] Since the mounting part 111 is installed on the top edge of the toilet bowl 21 as an independent toilet 20 accessory, users do not need to purchase a specially made toilet 20 or make destructive modifications to the existing toilet 20. They can easily install the suction part 11 on the existing toilet 20 and modify the existing toilet 20, thereby improving the convenience of use and reducing the cost of modifying the toilet 20 for deodorization. The design of the extension part 113 extending into the toilet bowl 21 allows the fan assembly 131 to more easily draw out air with a high concentration of odor molecules in the toilet bowl 21a, thereby faster discharging the air with a strong odor in the toilet bowl 21a to the sewage channel 30a, improving the deodorization efficiency and reducing the overall energy consumption of the toilet deodorization device 10.

[0039] Referring again to Figure 2, the suction mechanism 13 includes a housing 133 fixed relative to the toilet bowl 21. A fan assembly 131 is housed within the housing 133, which provides rigid support and protection for the fan assembly 131. The housing 133 has an air inlet 133a and an air outlet 133b. The air inlet 133a communicates with the suction member 11 through the suction member 11, and the air outlet communicates with the ventilation and drainage assembly 15. In this embodiment, the mounting portion 111 of the suction member 11 can protrude from the side of the toilet bowl 21, and the housing 133 is fixedly connected to the protruding portion of the suction member 11, improving the ease of assembly between the suction member 11 and the housing 133. Of course, the design of the suction member 11 protruding from the side of the toilet bowl 21 is not necessary; the housing 133 can be adapted by deformation or reliably connected to the suction member 11 via an intermediate connector.

[0040] In other embodiments, the housing 133 and the suction component 11 can be constructed as part or all of the toilet seat. In other words, in this embodiment, the suction component 11 and the fan assembly 131 of the suction mechanism 13 are integrated into the toilet seat 23. The toilet seat 23 can have all the functions of the suction component 11, while also providing rigid support and protection for the fan assembly 131. It is also relatively easy to configure the air inlet 133a and air outlet 133b in the toilet seat, thereby simplifying the structure of the toilet deodorizing device 10, reducing the number of parts, and improving the structural compactness of the toilet deodorizing device 10. In particular, in this embodiment, the suction component 11 and the fan assembly 131 can both be integrated into the toilet seat, that is, the toilet seat functions as both the suction component 11 and the housing 133. The toilet deodorizing device 10 has a higher structural compactness, and installation and use are more convenient for users.

[0041] The venting and drainage assembly 15 can have various structural forms. Referring to Figure 2, in a first embodiment, the venting and drainage assembly 15 includes an exhaust flange 151, which is disposed between the toilet drain outlet 21b and the sewage channel 30a. The position of the exhaust flange 151 is relatively fixed relative to the toilet drain outlet 21b and can be used to discharge sewage through the toilet 20. Referring to Figure 5, the exhaust flange 151 has a side interface 151a and an exhaust port 151b that are interconnected. The exhaust port 151b can be located on the bottom side or the inner side of the exhaust flange 151 and is connected to the sewage channel 30a. The side interface 151a is connected to the blower assembly 131.

[0042] Referring to Figures 6 and 7, the venting and drainage assembly 15 may further include a hollow bolt 153, which includes a hollow body 1531 and a connecting body 1533 protruding from the side of the hollow body 1531 and communicating with it. The mounting base of the toilet 20 may have at least one toilet mounting hole 21d, the hollow body 1531 passing through the toilet mounting hole 21d and communicating with the blower assembly 131, and the connecting body 1533 matching and connecting to the side interface 151a of the exhaust flange 151, thereby enabling the connecting body 1533 to communicate with the sewage channel 30a. During the operation of the toilet deodorizing device 10, the blower assembly 131 draws in air from the toilet bowl 21a through the air intake 113a. The air flows sequentially through the extension 113, the mounting part 111, the blower assembly 131, the hollow body 1531, the connector 1533, the exhaust flange 151, and the sewage channel 30a, thereby discharging the odor from the toilet bowl 21 to the sewage channel 30a and preventing the odor from the toilet 20 from spreading to the bathroom.

[0043] The hollow body 1531 of the hollow bolt 153 may have external threads, which are used to fit external nuts and washers, etc., to reliably fix the hollow bolt 153 to the toilet mounting hole 21d. The end 1534 of the hollow bolt 153 opposite to the hollow body 1531 can be installed in the toilet flange of the toilet 20, thereby reinforcing the fixation of the toilet 20 to the ground or floor.

[0044] As is well known, in some regions, a toilet mounting flange 31 can be installed between the toilet drain outlet 21b and the sewage channel 30a. The toilet mounting flange 31 and the sewage channel 30a are fixedly connected and fixed to the installation ground. In addition, the toilet 20 is also firmly connected to the toilet mounting flange 31 by toilet mounting bolts and nuts to provide the final effect of fixing the toilet 20 to the installation ground. In this case, an exhaust flange 151 can be installed on the toilet mounting flange 31, between the toilet drain outlet 21b and the toilet mounting flange 31. A sealing ring can also be provided between the exhaust flange 151 and the toilet mounting flange 31 for sealing, and the exhaust flange 151 and the toilet mounting flange 31 are connected by the end 1534 of the hollow bolt 153. Of course, in some embodiments, the toilet mounting flange 31 can be omitted, and the exhaust flange 151 can be directly set to correspond to the toilet drain outlet 21b and the sewage channel 30a.

[0045] Referring to Figure 8, the hollow bolt 153 can be omitted. In the second embodiment, the venting and drainage assembly 15 may also include a fixed or deformable hollow connecting pipe 154. When the toilet bowl 21 mounting base lacks the toilet mounting hole 21d, one end of the connecting pipe 154 is connected to the blower assembly 131, and the other end of the connecting pipe 154 can be connected to the side interface 151a, thereby enabling the connecting pipe 154 to be connected to the sewage channel 30a through the exhaust flange 15. In this embodiment, some or all of the connecting pipe 154 can be assembled and fixed to the side interface 151a of the exhaust flange 151, such as by insertion or snap-fit ​​fixing; the connecting pipe 154 can also be integrally connected to the exhaust flange 151, for example, by bonding or welding a portion of the connecting pipe 154 to the exhaust flange 151, or by directly injection molding to form an integrally connected connecting pipe 154 and exhaust flange 151. During the operation of the toilet deodorizing device 10, the blower assembly 131 draws in air from the toilet bowl 21a through the air intake 113a. The air flows sequentially through the extension 113, the mounting part 111, the blower assembly 131, the connecting pipe 154, the exhaust flange 151, and the sewage channel 30a, thereby discharging the odor from the toilet bowl 21a to the sewage channel 30a and preventing the odor from the toilet 20 from spreading to the bathroom. Generally, the connecting pipe 154 can extend into the toilet 20 through the opening at the rear of the toilet 20 and connect to the side interface 151a of the exhaust flange 151 through the open channel. Understandably, some toilets 20 may not have a suitable opening or channel to accommodate the extension of the connecting pipe 154, requiring manual processing of a suitable channel at the rear or bottom of the toilet 20 for the extension of the connecting pipe 154 and connection to the side interface 151a of the exhaust flange 151, including but not limited to drilling, enlarging, cutting, or grinding.

[0046] Referring to Figure 9, in the third embodiment, the venting and drainage assembly 15 includes a drain pipe 1551 extending along a first direction and a branch pipe 1553 protruding from the outer wall of the drain pipe 1551 and extending along a second direction. The drain pipe 1551 is connected to the toilet drain outlet 21b and the sewage channel 30a for sewage discharge, and the branch pipe 1553 is connected to the blower assembly 131 for gas flow. The first direction and the second direction are arranged at an angle. For example, the first direction is perpendicular to the second direction or is an acute angle, so that the branch pipe 1553 remains vertically upward or obliquely upward during use, providing a relatively large operating space for the assembly of the branch pipe 1553 and the vent pipe, improving the convenience of assembling the vent pipe and the branch pipe 1553, and minimizing the backflow of sewage from the sewage channel 30a into the branch pipe 1553. During the operation of the toilet deodorizing device 10, the blower assembly 131 draws in air from the toilet bowl 21a through the air intake 113a. The air flows sequentially through the extension 113, the mounting part 111, the blower assembly 131, the branch pipe 1553, the drain pipe fitting 1551, and the sewage channel 30a, thereby discharging the odor from the toilet bowl 21 to the sewage channel 30a and preventing the odor from the toilet 20 from spreading to the bathroom. Generally, this type of drain pipe fitting 1551 is used when the toilet drain outlet 21b points to the back of the toilet and the corresponding sewage channel 30a is installed on the back wall.

[0047] Referring to Figure 10, in the fourth embodiment, the ventilated drainage assembly 15 includes a first pipe portion 1561 extending along a first direction, a second pipe portion 1563 extending along a second direction, and a third pipe portion 1565 connecting the first pipe portion 1561 and the second pipe portion 1563. The first direction and the second direction are arranged at an angle, for example, the first direction is perpendicular to the second direction. The third pipe portion 1565 is curved and convex. A branch pipe 1553 communicating with the blower assembly 131 is provided on the convex surface of the third pipe portion 1565. The first pipe portion 1561, the second pipe portion 1563 and the third pipe portion 1565 are interconnected and connected between the toilet drain outlet 21b and the sewage channel 30a for sewage discharge. The branch pipe 1553 is connected to the blower assembly 131 for gas flow. In this implementation, the branch pipe 1553 is kept vertically or obliquely upward relative to the ground during use. This provides a relatively large operating space for assembling the branch pipe 1553 and the exhaust pipe, improving the convenience of assembling the exhaust pipe and the branch pipe 1553 and minimizing the backflow of sewage from the sewage channel 30a into the branch pipe 1553. During the operation of the toilet deodorization device 10, the blower assembly 131 draws in air from the toilet bowl 21a through the air intake 113a. The air flows sequentially through the extension 113, the mounting part 111, the blower assembly 131, the branch pipe 1553, the third pipe 1565, and the sewage channel 30a, thereby discharging the odor from the toilet bowl 21 to the sewage channel 30a and preventing the odor from the toilet 20 from spreading to the bathroom. Generally, this drainage method is used when the toilet drain outlet 21b points to the back of the toilet and the corresponding sewage channel 30a is located on the ground.

[0048] Referring to Figure 11, in the fifth embodiment, the venting and drainage assembly 15 includes a first connecting pipe 1571, a second connecting pipe 1573, and a retractable corrugated pipe 1575 connecting the first connecting pipe 1571 and the second connecting pipe 1573. The first connecting pipe 1571 has a branch pipe 1553 protruding from it, which is connected to the blower assembly 131. The first connecting pipe 1571, the second connecting pipe 1573, and the corrugated pipe 1575 are all connected to the toilet drain outlet 21b and the sewage channel 30a for sewage discharge. The branch pipe 1553 is connected to the blower assembly 131 for gas flow. In this embodiment, the branch pipe 1553 is kept vertically upward or obliquely upward relative to the ground during use, which provides a relatively large operating space for assembling the branch pipe 1553 and the exhaust pipe, improving the convenience of assembling the exhaust pipe and the branch pipe 1553 and minimizing the backflow of sewage from the sewage channel 30a into the branch pipe 1553. During the operation of the toilet deodorizing device 10, the blower assembly 131 draws in air from the toilet bowl 21a through the air intake 113a. The air flows sequentially through the extension 113, the mounting part 111, the blower assembly 131, the branch pipe 1553, the first connecting pipe 1571, the corrugated pipe 1575, the second connecting pipe 1573, and the sewage channel 30a, or sequentially through the extension 113, the mounting part 111, the blower assembly 131, the branch pipe 1553, the first connecting pipe 1571, and the sewage channel 30a, thereby discharging the odor from the toilet bowl 21 to the sewage channel 30a and preventing the odor from the toilet 20 from spreading to the bathroom. Generally, this drainage method is used when the toilet drain outlet 21b points to the back of the toilet and the corresponding sewage channel 30a is installed on the floor or wall.

[0049] Referring to Figures 12, 13, 14, 15 and 16, in the sixth embodiment, the venting and drainage assembly 15 is constructed as part or all of a displacement device, which includes a mounting cover 1581 and a connecting pipe 1583 connecting the mounting cover 1581 and the toilet drain outlet 21b. The mounting cover 1581 is used to fix the displacement device to the ground or other supporting surface, for example, by bolting the displacement device to the ground or other supporting surface. The mounting cover 1581 has a first channel 1581a, and the connecting pipe 1583 has a second channel 1583a. The second channel 1583a may include a vertical portion, a curved portion, and a horizontal portion. One of the connecting pipe 1583 and the mounting cover 1581 is provided with a branch pipe 1553 that connects to the blower assembly 131. Both the first channel 1581a and the second channel 1583a are connected to the sewage channel 30a for sewage discharge, and the branch pipe 1553 is connected to the blower assembly 131 for gas flow. During the operation of the toilet deodorizing device 10, the blower assembly 131 draws in air from the toilet bowl 21a through the air intake 113a. The air flows sequentially through the extension 113, the mounting portion 111, the blower assembly 131, the branch pipe 1553, the first channel 1581a, and the sewage channel 30a, thereby discharging the odor from the toilet bowl 21 to the sewage channel 30a and preventing the odor from the toilet 20 from spreading to the bathroom. Generally speaking, this drainage method is used when the sewage channel 30a is set on the ground and a displacement device is used.

[0050] In this embodiment, the branch pipe 1553 can protrude from the highest point of the mounting cover 1581 above the toilet 20 mounting surface and be perpendicular to the toilet 20 mounting surface, as shown in Figures 12, 13, and 14. During use, the branch pipe 1553 remains vertically upward relative to the ground, providing relatively large operating space for assembling the branch pipe 1553 and the exhaust pipe, improving the ease of assembly between the exhaust pipe and the branch pipe 1553, and minimizing the backflow of sewage from the sewage channel 30a into the branch pipe 1553. Of course, the branch pipe 1553 can also protrude from the vertical part of the connecting pipe 1583 and be set at an angle to the installation ground of the toilet 20, as shown in Figure 15. For example, the axis of the branch pipe 1553 extends obliquely upward relative to the vertical part of the connecting pipe 1583 and is set at an acute angle. During use, the branch pipe 1553 remains obliquely upward relative to the ground, providing a relatively large operating space for the assembly of the branch pipe 1553 and the exhaust pipe, improving the convenience of assembling the exhaust pipe and the branch pipe 1553, and minimizing the backflow of sewage from the sewage channel 30a into the branch pipe 1553.

[0051] Second embodiment:

[0052] The second embodiment of this application discloses a toilet deodorizing device 10 applied to a water closet carrier system, which includes an air intake 11, an air intake mechanism 13, and an air venting assembly 15'. The air intake 11 includes a mounting portion 111 and an extension portion 113 connected to the mounting portion 111. The mounting portion 111 is disposed on the top edge of the toilet bowl 21. Part or all of the extension portion 113 extends into the interior of the toilet bowl 21, including extending into the recessed toilet basin 21a of the toilet bowl 21 (Figures 1 and 3), or extending into the center of the upper opening 21a1 of the toilet bowl 21 (Figure 4). The extension portion 113 has a hollow structure and has an air intake 113a. Exemplarily, when a basically horizontal geometric plane is made tangent to the top edge of the toilet bowl 21, the air intake 113a of the extension portion 113 can be entirely located below the geometric plane, or it can be partially located below the geometric plane. The mounting section 111 has a hollow structure and an internal ventilation channel 111a that communicates with the air intake 113a to allow airflow. The air intake mechanism 13 includes a fan assembly 131 that connects to the ventilation channel 111a and the air intake 113a. The fan assembly 131 may include a motor and an impeller linked to the output shaft of the motor, which can guide airflow during operation. The fan assembly 131 can draw in air through the air intake 113a and guide the air directly from the ventilation assembly 15' into the exhaust duct 20e (FIG. 17) of the bracket 20, thereby discharging odors from the toilet bowl 21 to the exhaust duct 20e and preventing odors from the toilet 20 from spreading to the bathroom.

[0053] The difference from the first embodiment is that, in the second embodiment of this application, the ventilation component 15' is connected to the exhaust duct 20e of the bracket 25 of the bracket-type toilet system. The bracket 25 is generally fixedly installed on the ground, and the toilet 20 is generally fixedly installed on the bracket 25 in a wall-mounted manner. The exhaust duct 20e of the bracket 25 is correspondingly located above the drain pipe 20f behind the wall where the toilet 20 is installed. The ventilation component 15' may include a fixed or deformable hollow connecting pipe 154 and a ventilation element 156. The connecting pipe 154 is connected to the air intake mechanism 13, and the ventilation element 156 is connected to the exhaust duct 20e. The ventilation element 156 may adopt a three-way or side-connecting structure, and it may be connected to the exhaust duct 20e by a flexible connection or a rigid connection, so that the fan assembly 131 can draw in air through the air intake 113a and guide the air from the ventilation component 15' into the exhaust duct 20e. This implementation method eliminates the need for air to pass through sewage pipes, reducing mutual interference and allowing odors to be expelled more quickly and easily. Other structures and working principles of the toilet deodorizing device 10 can be found in the first embodiment of this application, and will not be repeated here.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
