Description

[Technical Field]

[0001] The present invention relates to the technical field of toilet accessories, and more particularly to a toilet deodorizing device. [Background technology]

[0002] In related art, in order to mitigate odors generated when using a toilet, ventilation devices such as exhaust fans are usually installed on the window or ceiling of the toilet to exhaust the odors from the toilet.

[0012] 1 and 2, a first embodiment of the present application discloses a toilet deodorizing device 10 including an air intake section 11, an air intake mechanism 13, and an air vent and drain assembly 15. The air intake section 11 includes a mounting section 111 and an extension section 113 connected to the mounting section 111. The mounting section 111 is provided on the upper edge of the toilet bowl 21, and a part or all of the extension section 113 extends toward the interior of the toilet bowl 21, such as toward the downwardly recessed water reservoir section 21a of the toilet bowl 21 (see FIGS. 1 and 3) or the center of the upper opening 21a1 of the toilet bowl 21 (see FIG. 4). The extension section 113 has a hollow structure and is provided with an air intake port 113a. For example, when a substantially horizontal geometric plane is in contact with the upper edge of the toilet bowl 21, the air intake port 113a of the extension section 113 may be located completely or partially below the geometric plane. The mounting portion 111 has a hollow structure and includes an air passage 111a communicating with the air intake 113a through which air flows. The air intake mechanism 13 includes a fan unit 131 communicating with the air passage 111a and the air intake 113a. The air ventilation and drainage assembly 15 is disposed between the toilet bowl drain 21b and the sewer 30a and communicates with the fan unit 131, allowing air to flow between the air ventilation and drainage assembly 15 and the fan unit 131. The fan unit 131 may include a motor and an impeller connected to the motor's output shaft, and can induce airflow during operation. The fan unit 131 draws air through the air intake 113a and directs the air from the air ventilation and drainage assembly 15 to the sewer 30a, thereby discharging odors from the toilet bowl 21 into the sewer 30a and preventing odors from the toilet bowl 20 from spreading throughout the toilet.

[0013] 1 and 2, in some embodiments, the intake portion 11 is a hollow plate, and the mounting portion 111 is assembled to the upper edge of the toilet bowl 21 to easily fix the intake portion 11 to the toilet bowl 20. The extension portion 113 and the mounting portion 111 may be integrally molded to improve molding efficiency of the intake portion 11. Of course, in another embodiment, the extension portion 113 may be assembled and fixed to the mounting portion 111. For example, the extension portion 113 may be assembled and fixed to the mounting portion 111 by a method such as a screw connection or a clamp connection. Furthermore, by detachably connecting the extension portion 113 to the mounting portion 111, a user can remove the extension portion 113 for easy cleaning or replacement.

[0014] The mounting portion 111 may be provided with mounting holes 111b, which are used to secure the air intake portion 11 and fit into the toilet seat mounting holes 21c. The mounting holes 111b may have a relatively large diameter to accommodate toilet seats of different sizes. For example, in the embodiment shown in FIG. 1, two mounting holes 111b are provided spaced apart along the longitudinal direction of the mounting portion 111, and these two mounting holes 111b correspond one-to-one to the toilet seat mounting holes 21c of the toilet bowl 21. This allows the air intake portion 11 to be easily assembled to the toilet bowl 21 and the toilet seat.

[0015] Furthermore, the air intake unit 11 can include an adjustment piece 115 connected to the mounting unit 111, which may be movably positioned within the mounting hole 111b. In some embodiments, the mounting hole 111b has a shape such as a circle, a rectangle, or a rounded rectangle to accommodate toilet seat mounting holes 21c with different spacing and positions, thereby improving the versatility of the air intake unit 11. The adjustment piece 115 fits into the mounting hole 111b and has a mounting through-slot 115a that is longer than the diameter of the toilet seat mounting hole 21c. After the adjustment piece 115 is inserted into the mounting hole 111b, the adjustment piece 115 can rotate within the mounting hole 111b relative to the mounting unit 111 to change the relative position of the mounting through-slot 115a and the mounting hole 111b. As a result, the mounting through-slot 115a can be aligned with the toilet seat mounting hole 21c, and the toilet seat can be assembled and fixed to the toilet seat mounting hole 21c of the toilet bowl 21 using fasteners such as bolts.

[0016] Furthermore, in some embodiments, after the adjustment piece 115 is embedded in the assembly hole 111b, its upper end surface does not protrude from the upper end surface of the mounting part 111; for example, the upper end surface of the adjustment piece 115 is made flush with the upper end surface of the mounting part 111, or is recessed downward relative to the upper end surface of the mounting part 111, thereby increasing the compactness of the air intake part 11 and preventing an increase in the thickness of the air intake part 11 from excessively increasing the height of the toilet seat relative to the upper edge of the toilet bowl 21, which would affect the comfort of use.

[0017] In another embodiment, the air intake section 11 can be modified in various ways. For example, the air intake section 11 shown in Figures 1 and 2 can be replaced with a specially designed toilet seat 23 shown in Figures 3 or 4. In this case, the air intake section 11 and the toilet seat 23 are integrated, which is considered to reduce the number of parts and increase the compactness of the structure. These modifications should be considered as equivalent alternatives to the air intake section 11 of the present application and should not be excluded from the scope of protection of the present application. No further examples will be given.

[0018] The toilet deodorizing device 10 includes an air intake section 11, an air intake mechanism 13, and an air vent / drain assembly 15. The air intake section 11 includes a mounting section 111 and an extension section 113 connected to the mounting section 111. The mounting section 111 is provided on the upper edge of the toilet bowl 21, and the extension section 113 extends toward the interior of the toilet bowl 21. The extension section 113 has a hollow structure and is provided with an air intake port 113a. The mounting section 111 also has a hollow structure and is provided with an air passage 111a therein that communicates with the air intake port 113a and allows air to flow. The air intake mechanism 13 includes a fan unit 131 that communicates with the air passage 111a and the air intake port 113a. The air vent / drain assembly 15 is provided between the toilet drain port 21b and the sewer 30a, and is connected to the fan unit 131. The fan unit 131 can draw air through the air intake 113a and direct the air from the ventilation and drainage assembly 15 to the sewer 30a, thereby discharging odors in the toilet bowl 21 into the sewer 30a and preventing odors in the toilet bowl 20 from spreading throughout the toilet.

[0019] Furthermore, because the mounting part 111 is attached to the upper edge of the toilet bowl 21 as an accessory separate from the toilet bowl 20, the user does not need to purchase a dedicated toilet 20 or perform destructive processing on the existing toilet bowl 20. The air intake part 11 can be easily attached to the existing toilet bowl 20 to improve the existing toilet 20, thereby improving usability and reducing the cost of improving the deodorization of the toilet 20. The structure in which the extension part 113 extends into the toilet bowl 21 allows the fan unit 131 to easily suck in air containing high concentrations of odorous molecules within the toilet bowl 21a, quickly discharging the air with high odor concentrations within the toilet bowl 21a to the sewer 30a, improving deodorizing efficiency and reducing the energy consumption of the toilet deodorizing device 10.

[0020] 2, the air intake mechanism 13 includes an outer shell 133 that is fixed relative to the position of the toilet bowl 21, the fan unit 131 is disposed within the outer shell 133, and the outer shell 133 ensures the support rigidity of the fan unit 131 and protects it. The outer shell 133 is provided with an air intake port 133a and an exhaust port 133b, the air intake port 133a communicating with the air intake port 113a via the air intake section 11, and the exhaust port communicating with the ventilation and drainage assembly 15. In this embodiment, the mounting section 111 of the air intake section 11 may protrude from the side surface of the toilet bowl 21, and the outer shell 133 is fixedly connected to the portion of the air intake section 11 that protrudes from the side surface of the toilet bowl 21, improving the ease of assembly of the air intake section 11 and the outer shell 133. Of course, it is not essential that the air intake portion 11 protrude from the side of the toilet bowl 21; it is sufficient if the outer shell 133 is appropriately deformed or securely attached to the air intake portion 11 by an intermediate connector.

[0021] In other embodiments, the outer shell 133 and the air intake unit 11 may together form part or all of the toilet seat. That is, in this embodiment, the air intake unit 11 and the fan unit 131 of the air intake mechanism 13 are integrated into the toilet seat 23, so that the toilet seat 23 can perform all of the functions of the air intake unit 11 while also ensuring the support rigidity of and protecting the fan unit 131. Furthermore, since it is relatively easy to provide the air intake port 133a and the air exhaust port 133b in the toilet seat, the structure of the toilet deodorizing device 10 is simplified, the number of parts is reduced, and the toilet deodorizing device 10 is made more compact. In particular, in this embodiment, the air intake unit 11 and the fan unit 131 can both be integrated into the toilet seat, meaning that the toilet seat can perform the functions of the air intake unit 11 and the outer shell 133, making the toilet deodorizing device 10 more compact and easier for users to install and use.

[0022] The ventilation and drainage assembly 15 can take various structural forms. Referring to Fig. 2, in a first embodiment, the ventilation and drainage assembly 15 includes an exhaust flange 151, which is provided between the toilet drain outlet 21b and the sewer 30a and is fixed in position relative to the toilet drain outlet 21b, allowing drainage from the toilet 20 to flow therethrough. Referring to Fig. 5, the exhaust flange 151 is provided with a side connection port 151a and an exhaust port 151b that communicate with each other, the exhaust port 151b is located at the bottom or inside of the exhaust flange 151 and communicates with the sewer 30a, and the side connection port 151a communicates with the fan unit 131.

[0023] 6 and 7, the ventilation and drainage assembly 15 may further include a hollow bolt 153, which includes a hollow body 1531 and a connector 1533 protruding from a side surface of the hollow body 1531 and communicating with the hollow body 1531. The mounting base of the toilet 20 is provided with at least one toilet mounting hole 21d, and the hollow body 1531 is disposed through the toilet mounting hole 21d and communicates with the fan unit 131. The connector 1533 fits into and connects to the side connection port 151a of the exhaust flange 151, thereby communicating with the sewer 30a. When the toilet deodorizing device 10 is in operation, the fan unit 131 draws in air from within the toilet bowl 21a through the air intake 113a, and the air flows through the extension 113, the mounting portion 111, the fan unit 131, the hollow body 1531, the connector 1533, the exhaust flange 151, and the sewer 30a in that order. This allows odors from within the toilet bowl 21 to be discharged into the sewer 30a, preventing odors from within the toilet 20 from spreading throughout the restroom.

[0024] The hollow body 1531 of the hollow bolt 153 may be externally threaded to accommodate accessories such as external nuts and washers that are used to securely fasten the hollow bolt 153 to the toilet mounting hole 21d. The end 1534 of the hollow bolt 153 opposite the hollow body 1531 can be attached within the toilet flange of the toilet 20, thereby strengthening the fixation of the toilet 20 to the ground or floor.

[0025] As is well known, in some regions, a toilet mounting flange 31 is installed between the toilet drain 21b and the sewer 30a. The toilet mounting flange 31 is fixedly connected to the sewer 30a and fixed to the mounting floor, and the toilet 20 is also securely connected to the toilet mounting flange 31 with toilet mounting bolts and nuts, resulting in the net effect of the toilet 20 being fixedly attached to the mounting floor. In this case, an exhaust flange 151 can be disposed above the toilet mounting flange 31, between the toilet drain 21b and the toilet mounting flange 31, and a sealing ring can be provided between the exhaust flange 151 and the toilet mounting flange 31, and the exhaust flange 151 and the toilet mounting flange 31 can be connected via the ends 1534 of hollow bolts 153. Of course, in some embodiments, the toilet mounting flange 31 can be omitted, and the exhaust flange 151 can be directly installed corresponding to the toilet drain 21b and the sewer 30a.

[0026] Referring to FIG. 8 , the hollow bolt 153 may be omitted, and in a second embodiment, the ventilation and drainage assembly 15 may include a fixed or variable hollow toilet connection portion 154. When the mounting base of the toilet bowl 21 does not have a toilet mounting hole 21d, one end of the toilet connection portion 154 communicates with the fan unit 131 and the other end of the toilet connection portion 154 communicates with the side connection port 151a, thereby allowing the toilet connection portion 154 to communicate with the sewer system 30a via the exhaust flange 15. In this embodiment, a part or all of the toilet connection portion 154 may be assembled and fixed to the side connection port 151a of the exhaust flange 151 by a method such as insertion or snap lock. Furthermore, for example, a part of the toilet connection portion 154 may be glued or welded to the exhaust flange 151 to integrally connect the toilet connection portion 154 to the exhaust flange 151, or the toilet connection portion 154 and the exhaust flange 151 may be directly connected to each other by injection molding. During operation of the toilet deodorizing device 10, the fan unit 131 draws air from the toilet bowl 21a through the air intake 113a, and the air flows sequentially through the extension 113, the mounting portion 111, the fan unit 131, the connector 154, the exhaust flange 151, and the sewer 30a. This allows odors from within the toilet bowl 21 to be discharged into the sewer 30a, preventing odors from spreading throughout the toilet. Generally, the toilet connection 154 extends into the interior of the toilet 20 through an opening at the rear of the toilet 20 and can be connected to the side connection port 151a of the exhaust flange 151 via an open passage. It should be understood that some toilets 20 may not have an appropriate opening or passage for the toilet connection 154 to extend through. A suitable passage must be manually formed at the rear or bottom of the toilet 20 so that the toilet connection 154 can extend and connect to the side connection port 151a of the exhaust flange 151. This includes, but is not limited to, processes such as drilling, reaming, cutting, or polishing.

[0027] 9 , in the third embodiment, the ventilation and drainage assembly 15 includes a drain pipe portion 1551 extending in a first direction and a branch pipe 1553 protruding from the outer wall of the drain pipe portion 1551 and extending in a second direction. The drain pipe portion 1551 communicates with the toilet drain outlet 21b and the sewer 30a to discharge wastewater, and the branch pipe 1553 communicates with the fan unit 131 to circulate air. The first and second directions are disposed at an angle. For example, by having the first direction perpendicular or at an acute angle to the second direction, the branch pipe 1553 can be maintained facing vertically upward or diagonally upward during use, thereby ensuring a relatively large working space for assembling the branch pipe 1553 and the exhaust pipe. This facilitates the assembly of the exhaust pipe and the branch pipe 1553 and minimizes backflow of wastewater from the sewer 30a to the branch pipe 1553. When the toilet deodorizing device 10 is in operation, the fan unit 131 draws in air from within the toilet bowl 21a through the air intake 113a, and the air flows through the extension 113, the mounting portion 111, the fan unit 131, the branch pipe 1553, the drain pipe 1551, and the sewer 30a in that order. This allows odors from within the toilet bowl 21 to be discharged into the sewer 30a, preventing odors from within the toilet 20 from spreading throughout the restroom. Typically, this type of drain pipe 1551 is used when the toilet drain outlet 21b faces the rear of the toilet and the corresponding sewer 30a is installed on the rear wall.

[0028] 10 , in the fourth embodiment, the ventilation and drainage assembly 15 includes a first pipe 1561 extending in a first direction, a second pipe 1563 extending in a second direction, and a third pipe 1565 connected between the first pipe 1561 and the second pipe 1563, the first and second directions being disposed at an angle. For example, the first direction is perpendicular to the second direction, and the third pipe 1565 has a curved convex shape. A branch pipe 1553 connected to the fan unit 131 protrudes from the outer convex surface of the third pipe 1565. The first pipe 1561, the second pipe 1563, and the third pipe 1565 are connected to one another and communicate with the toilet drain 21b and the sewer 30a to discharge wastewater, and the branch pipe 1553 communicates with the fan unit 131 to circulate air. In this embodiment, the branch pipe 1553 is maintained facing vertically upward or diagonally upward relative to the floor during use, ensuring a relatively large working space for assembling the branch pipe 1553 and the exhaust pipe. This facilitates the assembly of the exhaust pipe and branch pipe 1553 and minimizes backflow of sewage from the sewer 30a into the branch pipe 1553. During operation of the toilet deodorizing device 10, the fan unit 131 draws air from within the toilet basin 21a through the air intake 113a, and the air flows sequentially through the extension 113, the mounting portion 111, the fan unit 131, the branch pipe 1553, the third pipe 1565, and the sewer 30a. This allows odors within the toilet bowl 21 to be exhausted into the sewer 30a, preventing odors within the toilet 20 from spreading throughout the toilet. Typically, this type of drainage method is used when the toilet drain outlet 21b faces the rear of the toilet and the corresponding sewer 30a is installed on the floor.

[0029] 11, in the fifth embodiment, the ventilation and drainage assembly 15 includes a first toilet connection portion 1571, a second toilet connection portion 1573, and an expandable and contractible corrugated pipe 1575 connected between the first toilet connection portion 1571 and the second toilet connection portion 1573, a branch pipe 1553 communicating with the fan unit 131 protruding from the first toilet connection portion 1571, the first toilet connection portion 1571, the second toilet connection portion 1573, and the corrugated pipe 1575 all communicating with the toilet drain outlet 21b and the sewer 30a to discharge wastewater, and the branch pipe 1553 communicating with the fan unit 131 to circulate air. In this embodiment, the branch pipe 1553 is kept facing vertically upward or diagonally upward relative to the floor during use, ensuring a relatively large working space for assembling the branch pipe 1553 and the exhaust pipe. This simplifies the assembly of the exhaust pipe and branch pipe 1553 and minimizes backflow of sewage from the sewer 30a to the branch pipe 1553. During operation of the toilet deodorizing device 10, the fan unit 131 draws air into the toilet bowl 21a through the air intake 113a, and the air flows sequentially through the extension 113, mounting portion 111, fan unit 131, branch pipe 1553, first toilet connection portion 1571, corrugated pipe 1575, second toilet connection portion 1573, and sewer 30a, or through the extension 113, mounting portion 111, fan unit 131, branch pipe 1553, first toilet connection portion 1571, and sewer 30a. This allows odors within the toilet bowl 21 to be exhausted into the sewer 30a, preventing odors within the toilet 20 from spreading throughout the toilet. Typically, this type of drainage method is used when the toilet drain outlet 21b faces the rear of the toilet and the corresponding sewer 30a is installed in the floor or wall.

[0030] 12, 13, 14, 15, and 16, in the sixth embodiment, the air vent drain assembly 15 is configured as part or all of a drain adjuster, the drain adjuster including a flange connection portion 1581 and a toilet connection portion 1583 connected between the flange connection portion 1581 and the toilet drain opening 21b, the flange connection portion 1581 being used to secure the drain adjuster to a floor or other supporting surface, for example, by bolts. A first passage 1581a is provided in the flange connection part 1581, and a second passage 1583a is provided in the toilet connection part 1583, with the second passage 1583a having a vertical section, a curved section, and a horizontal section, and a branch pipe 1553 communicating with the fan unit 131 is provided protruding from one of the toilet connection part 1583 and the flange connection part 1581, and both the first passage 1581a and the second passage 1583a communicate with the sewer 30a to discharge sewage, and the branch pipe 1553 communicates with the fan unit 131 to circulate air. During operation of the toilet deodorizing device 10, the fan unit 131 sucks air within the toilet basin 21a through the air intake 113a, and the air flows sequentially through the extension part 113, the mounting part 111, the fan unit 131, the branch pipe 1553, the first passage 1581a, and the sewer 30a. This allows odors in the toilet bowl 21 to be discharged into the sewer 30a, preventing odors in the toilet 20 from spreading throughout the toilet. This type of drainage method is usually used when the sewer 30a is installed on the floor and a drain adjuster is used.

[0031] In this embodiment, as shown in Figures 12, 13, and 14, the branch pipe 1553 may be provided at the flange connection portion 1581 to protrude to the highest position from the floor on which the toilet 20 is installed, and may be perpendicular to the floor on which the toilet 20 is installed. Since the branch pipe 1553 is kept facing vertically upward relative to the floor during use, a relatively large working space can be secured for assembling the branch pipe 1553 and the exhaust pipe. This facilitates the assembling work of the exhaust pipe and the branch pipe 1553, and minimizes the backflow of sewage from the sewer 30a into the branch pipe 1553. Of course, the branch pipe 1553 may also be provided to protrude from the vertical portion of the toilet connection portion 1583, and may be arranged at an angle to the floor on which the toilet 20 is installed. 15, for example, if the axis of branch pipe 1553 extends diagonally upward to form an acute angle with the vertical part of toilet connection part 1583, branch pipe 1553 will be kept facing diagonally upward with respect to the floor during use, ensuring a relatively large working space for assembling branch pipe 1553 and exhaust pipe. This makes it easier to assemble the exhaust pipe and branch pipe 1553, and minimizes the backflow of sewage from sewer 30a into branch pipe 1553. [Example]

[0032] A second embodiment of the present application discloses a toilet deodorizing device 10 for use in a water closet carrier system, which includes an air intake section 11, an air intake mechanism 13, and a ventilation assembly 15'. The air intake section 11 includes a mounting section 111 and an extension section 113 connected to the mounting section 111. The mounting section 111 is provided on the upper edge of the toilet bowl 21, and a part or all of the extension section 113 extends toward the interior of the toilet bowl 21, such as toward the downwardly recessed water reservoir section 21a of the toilet bowl 21 (FIGS. 1 and 3) or the center of the upper opening 21a1 of the toilet bowl 21 (FIG. 4). The extension section 113 has a hollow structure and is provided with an air intake port 113a. For example, when a substantially horizontal geometric plane is in contact with the upper edge of the toilet bowl 21, the air intake port 113a of the extension section 113 may be located completely or partially below the geometric plane. The mounting portion 111 has a hollow structure and includes an air passage 111a communicating with the air intake port 113a through which air flows. The air intake mechanism 13 includes a fan unit 131 communicating with the air passage 111a and the air intake port 113a. The fan unit 131 may include a motor and an impeller connected to the motor's output shaft, and can induce airflow during operation. The fan unit 131 draws air through the air intake port 113a and directs the air from the ventilation assembly 15' directly to the exhaust duct 20e (FIG. 17) of the bracket 25, thereby discharging odors within the toilet bowl 21 into the exhaust duct 20e and preventing odors within the toilet bowl 20 from spreading throughout the toilet.

[0033] The difference from the first embodiment is that the ventilation assembly 15' of the second embodiment of the present application is connected to the exhaust duct 20e of the bracket 25 of a bracket-type toilet system. The bracket 25 is usually fixedly installed on the floor, and the corresponding toilet 20 is usually fixedly attached to the bracket 25 in a wall-mounted manner, with the exhaust duct 20e of the bracket 25 correspondingly attached above the drain pipe 20f at the rear of the mounting wall of the toilet 20. The ventilation assembly 15' includes a fixed or variable hollow toilet connection part 154 and an air vent part 156. The toilet connection part 154 is connected to the air intake mechanism 13, and the air vent part 156 is connected to the exhaust duct 20e. The air vent part 156 may have a Y-shaped or side pipe structure and can be connected to the exhaust duct 20e by a flexible joint or a rigid connection. This allows the fan unit 131 to draw air through the air intake port 113a and direct the air from the ventilation assembly 15' to the exhaust duct 20e. This embodiment eliminates the need to pass air through the sewer, reducing interference and allowing odors to be discharged more quickly and easily. For other structures and operating principles of the toilet deodorizing device 10, please refer to the first embodiment of this application and a detailed description will be omitted here.

[0034] While the present invention has been shown and described in terms of a preferred embodiment and several alternatives, it is not intended to be limited to the specific descriptions contained herein, and other alternatives or equivalent parts may be used to practice the present invention.
