[0051] First Embodiment

[0052] refer to Figure 1 and Figure 2 The first embodiment of this application discloses a toilet deodorizing device 10, which includes an air intake 11, an air intake mechanism 13, and an air-venting 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 toilet basin 21a that is recessed downwards from the toilet bowl 21 (see reference). Figure 1 , Figure 3 ) or towards the middle of the upper opening 21a1 of the toilet bowl 21 (see reference) Figure 4) extends. The extension 113 is a hollow structure and has an air suction port 113a. Exemplarily, when a substantially horizontal geometric plane is tangent to the top edge of the toilet bowl 21, the air suction port 113a of the extension 113 can be located entirely below the geometric plane or partially below the geometric plane. The mounting portion 111 is a hollow structure and has an air passage 111a inside for air flow in communication with the air suction port 113a. The air suction mechanism 13 includes a fan assembly 131 in communication with the air passage 111a and the air suction port 113a. The air passage and drainage assembly 15 is arranged between the toilet drain 21b and the sewage passage 30a, and the air passage and drainage assembly 15 is in communication with the fan assembly 131, i.e. air can flow between the air passage and drainage assembly 15 and the fan assembly 131. The fan assembly 131 can include a motor and an impeller linked to the output shaft of the motor, which can guide air flow when in operation. The fan assembly 131 can suck air through the air suction port 113a and guide the air to enter the sewage passage 30a from the air passage and drainage assembly 15, so as to discharge the odor in the toilet bowl 21 to the sewage passage 30a and prevent the odor in the toilet 20 from spreading to the washroom.

[0053] With reference to Figure 1 and Figure 2 In some embodiments, the air suction member 11 is in the form of a hollow plate, and the mounting portion 111 is used to assemble to the top edge of the toilet bowl 21 to facilitate assembly and fixation of the air suction member 11 to the toilet 20. The extension 113 and the mounting portion 111 can be integrally formed to improve the forming efficiency of the air suction member 11. Of course, in other embodiments, the extension 113 can also be assembled and fixed to the mounting portion 111, for example by threaded connection, or by clamping, etc. to achieve assembly and fixation of the extension 113 to the mounting portion 111, and to achieve detachable connection of the extension 113 to the mounting portion 111 to facilitate users to detach the extension 113 for cleaning or replacement.

[0054] The mounting portion 111 can be provided with assembly holes 111b for fixing the air suction member 11 and adapting the toilet seat mounting holes 21c. The assembly holes 111b can have a relatively large hole diameter to match toilet seats of different sizes. For example, in the embodiment shown in Figure 1 The assembly holes 111b are arranged in pairs at intervals in the length extension direction of the mounting portion 111, and the two assembly holes 111b correspond one-to-one to the toilet seat mounting holes 21c on the toilet bowl 21, so as to facilitate assembly of the air suction member 11 to the toilet bowl 21 and the toilet seat.

[0055] 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.

[0056] 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.

[0057] In other embodiments, the intake element 11 may have further variations, such as employing... Figure 3 or Figure 4 The specially designed toilet seat 23 shown is a replacement. Figure 1 , Figure 2 The suction component 11 shown can be considered as integrated with the toilet seat 23, thereby reducing the number of parts and improving the compactness of the structure. These modifications 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.

[0058] The above toilet deodorization device 10 comprises an air suction member 11, an air suction mechanism 13 and a ventilation and drainage assembly 15. The air suction member 11 comprises a mounting portion 111 and an extension portion 113 connected to the mounting portion 111. The mounting portion 111 is arranged 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 suction port 113a. The mounting portion 111 is also hollow and has an air ventilation channel 111a inside, which is in communication with the air suction port 113a for air flow. The air suction mechanism 13 comprises a fan assembly 131, which is in communication with the air ventilation channel 111a and the air suction port 113a. The ventilation and drainage assembly 15 is arranged between the toilet drain 21b and the sewage channel 30a, and is in communication with the fan assembly 131. The fan assembly 131 can suck air through the air suction port 113a and guide the air from the ventilation and drainage 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 washroom.

[0059] Since the mounting portion 111 is mounted on the top edge of the toilet bowl 21, as an independent toilet 20 accessory, users do not need to purchase special toilet 20 or perform destructive processing on existing toilet 20. The air suction member 11 can be conveniently installed on the existing toilet 20 for modification, thereby improving the convenience of use and reducing the modification cost of the toilet 20 deodorization. The design of the extension portion 113 extending into the toilet bowl 21 makes it easier for the fan assembly 131 to extract air with a higher concentration of odor molecules in the toilet bowl 21a, thereby faster discharging the air with heavier odor in the toilet bowl 21a to the sewage channel 30a, improving the efficiency of deodorization and reducing the overall energy consumption of the toilet deodorization device 10.

[0060] Continuing to refer to Figure 2 , the air suction mechanism 13 comprises a housing 133 fixed relative to the position of the toilet bowl 21, and the fan assembly 131 is arranged in the housing 133. The housing 133 provides rigid support for the fan assembly 131 and protects the fan assembly 131. The housing 133 has an air inlet 133a and an air outlet 133b. The air inlet 133a is in communication with the air suction port 113a through the air suction member 11, and the air outlet is in communication with the ventilation and drainage assembly 15. In this embodiment, the mounting portion 111 of the air suction member 11 can protrude from the side of the toilet bowl 21, and the housing 133 is fixedly connected to the part of the air suction member 11 protruding from the side of the toilet bowl 21, thereby improving the assembly convenience of the air suction member 11 and the housing 133. Of course, the design of the air suction member 11 protruding from the side of the toilet bowl 21 is not necessary, and the housing 133 can be adaptively deformed or reliably connected to the air suction member 11 through an intermediate connecting member.

[0061] In other embodiments, the shell 133 and the air suction member 11 can be jointly configured as part or all of the toilet seat. In other words, in such embodiments, the air suction member 11 and the fan assembly 131 of the air suction mechanism 13 are integrated into the toilet seat 23, which can have all the functions of the air suction member 11 while providing rigid support for and protection of the fan assembly 131. It is relatively easy to configure the air inlet 133a and the air outlet 133b in the toilet seat, thereby simplifying the structure of the toilet deodorization device 10, reducing the number of components, and improving the compactness of the toilet deodorization device 10. In particular, in such embodiments, the air suction member 11 and the fan assembly 131 can be integrated into the toilet seat, i.e., the toilet seat functions as the air suction member 11 and the shell 133, the toilet deodorization device 10 has higher compactness, and the user can install and use it more conveniently.

[0062] The air venting and draining assembly 15 can have various structural forms. Referring to Figure 2 In a first embodiment, the air venting and draining assembly 15 includes an air exhaust flange 151, which is arranged between the toilet drain 21b and the sewage channel 30a, is fixed relative to the position of the toilet drain 21b and is used for discharging the sewage discharged through the toilet 20, in combination with Figure 5 The air exhaust flange 151 has a side interface 151a and an air outlet 151b that are in communication with each other, the air outlet 151b can be located at the bottom side or the inner side of the air exhaust flange 151 and is communicated to the sewage channel 30a, and the side interface 151a is communicated to the fan assembly 131.

[0063] In combination with Figure 6 and Figure 7 The air venting and draining assembly 15 can further include a hollow bolt 153, which includes a hollow main body 1531 and a connecting body 1533 protruding from the side of the hollow main body 1531 and communicated to the hollow main body 1531. The mounting base of the toilet 20 can have at least one toilet mounting hole 21d, the hollow main body 1531 is arranged in the toilet mounting hole 21d and communicated to the fan assembly 131, the connecting body 1533 is matched with the side interface 151a of the air exhaust flange 151 and connected in the side interface 151a, so that the connecting body 1533 is communicated to the sewage channel 30a. During the operation of the toilet deodorization device 10, the fan assembly 131 sucks the air in the toilet bowl 21a through the air suction port 113a, and the air flows through the extension 113, the mounting portion 111, the fan assembly 131, the hollow main body 1531, the connecting body 1533, the air exhaust flange 151 and the sewage channel 30a in sequence, 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 washroom.

[0064] The hollow body 1531 of the hollow bolt 153 can have external threads for fitting accessories such as external nuts and washers to securely 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 mounted in the toilet flange of the toilet 20 to reinforce the fixing of the toilet 20 to the ground or floor.

[0065] As is well known, in some areas, a toilet mounting flange 31 can be provided between the toilet drain 21b and the sewage channel 30a, the toilet mounting flange 31 being fixedly connected to the sewage channel 30a and fixed to the installation ground, and the toilet 20 being stably 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, the exhaust flange 151 can be arranged on the toilet mounting flange 31 between the toilet drain 21b and the toilet mounting flange 31, a sealing ring can 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 can be 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 arranged corresponding to the toilet drain 21b and the sewage channel 30a.

[0066] Reference Figure 8, the hollow bolt 153 can be omitted, in the second embodiment, the air-ventilation and drainage assembly 15 can further comprise a fixed or deformable hollow connecting pipe 154, in the state that the mounting base of the toilet bowl 21 lacks the toilet mounting hole 21d, one end of the connecting pipe 154 is communicated to the fan assembly 131, the other end of the connecting pipe 154 can be communicated with the side interface 151a, thereby realizing that the connecting pipe 154 is communicated to the sewage channel 30a through the exhaust flange 151. In this embodiment, part or all of the connecting pipe 154 can be assembled and fixed with the side interface 151a of the exhaust flange 151, for example, inserted or buckled fixed, etc.; the connecting pipe 154 can also be integrally connected to the exhaust flange 151, for example, part of the connecting pipe 154 is adhesively fixed or fusion-welded to the exhaust flange 151, or directly injection-molded to form an integrally connected connecting pipe 154 and exhaust flange 151. In the working process of the toilet deodorization device 10, the fan assembly 131 sucks the air in the toilet pool 21a through the air suction port 113a, and the air flows through the extension 113, the mounting portion 111, the fan assembly 131, the connecting pipe 154, the exhaust flange 151 and the sewage channel 30a in turn, thereby discharging the odor in the toilet bowl 21 to the sewage channel 30a, preventing the odor in the toilet 20 from spreading to the washroom. Generally speaking, the connecting pipe 154 can extend into the toilet 20 through the opening at the rear of the toilet 20 and be connected through the open channel and the side interface 151a of the exhaust flange 151. It can be understood that some toilets 20 can not have a suitable opening or channel to accommodate the extension of the connecting pipe 154, and it is necessary to manually process a suitable channel at the rear or bottom of the toilet 20 for the connecting pipe 154 to extend and be connected with the side interface 151a of the exhaust flange 151, including but not limited to drilling, reaming, cutting or grinding processing methods.

[0067] Reference Figure 9In the third embodiment, the air venting and draining assembly 15 comprises a drain pipe 1551 extending in a first direction, and a branch pipe 1553 extending in a second direction and protruding from the outer wall of the drain pipe 1551, the drain pipe 1551 being in communication with the toilet drain 21b and the sewage channel 30a for sewage discharge, and the branch pipe 1553 being in communication with the fan assembly 131 for air flow, the first direction being arranged at an angle with the second direction. For example, the first direction is perpendicular to the second direction or is at an acute angle, so that the branch pipe 1553 is kept in a vertical upward state or an inclined upward state during use, providing a relatively large operation space for the assembly of the branch pipe 1553 and the exhaust pipe, improving the convenience of the assembly of the exhaust pipe and the branch pipe 1553 and minimizing the backflow of sewage in the sewage channel 30a into the branch pipe 1553. During the operation of the toilet deodorizing device 10, the fan assembly 131 sucks the air in the toilet bowl 21a through the air inlet 113a, and the air flows sequentially through the extension 113, the mounting portion 111, the fan assembly 131, the branch pipe 1553, the drain pipe 1551 and 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 washroom. Generally, the toilet drain 21b is directed to the rear of the toilet, and the corresponding sewage channel 30a is arranged on the rear wall, so this drain pipe 1551 is used.

In use, the branch pipe 1553 remains obliquely upward relative to the ground, providing a relatively large operation space for assembly of the branch pipe 1553 and the exhaust pipe, improving the convenience of assembly of the exhaust pipe and the branch pipe 1553, and minimizing the backflow of sewage in the sewage passage 30a to the branch pipe 1553.

[0072] Second Embodiment

[0073] The second embodiment of the present application discloses a toilet deodorization device 10 applied to a water closet carrier system, which comprises an air suction member 11, an air suction mechanism 13 and an air outlet assembly 15'. The air suction member 11 comprises a mounting portion 111 and an extension portion 113 connected to the mounting portion 111. The mounting portion 111 is arranged on the top edge of a toilet bowl 21. Part or all of the extension portion 113 extends into the toilet bowl 21, including extending into a toilet pool 21a which is concave downwardly to the toilet bowl 21, Figure 1 , Figure 3 ), or extending into the middle of an upper opening 21a1 of the toilet bowl 21 Figure 4 . The extension portion 113 is a hollow structure and has an air suction port 113a. Exemplarily, when a basic horizontal geometric plane is tangent to the top edge of the toilet bowl 21, the air suction port 113a of the extension portion 113 can be located below the geometric plane or partially below the geometric plane. The mounting portion 111 is a hollow structure and has an air outlet channel 111a inside which is in communication with the air suction port 113a for air flow. The air suction mechanism 13 comprises a fan assembly 131 which is in communication with the air outlet channel 111a and the air suction port 113a. The fan assembly 131 can comprise a motor and an impeller which is linked with the output shaft of the motor and can guide air flow in operation. The fan assembly 131 can suck air through the air suction port 113a and guide the air to directly enter an exhaust duct 20e of a carrier 20 from the air outlet assembly 15' Figure 17 , so as to discharge the odor in the toilet bowl 21 to the exhaust duct 20e and prevent the odor in the toilet 20 from spreading to a washroom.

[0074] The difference between the first embodiment and the second embodiment of the present application is that the air outlet assembly 15' of the second embodiment is connected to the exhaust duct 20e of a carrier 25 of the water closet carrier system. The carrier 25 is generally fixedly installed on the ground, and the corresponding toilet 20 is generally fixedly installed on the carrier 25 in a wall-hanging manner. The exhaust duct 20e of the carrier 25 is arranged above a drain pipe 20f which is behind the wall on which the toilet 20 is installed. The air outlet assembly 15' can comprise a fixed or deformable hollow connecting pipe 154 and an air outlet member 156. The connecting pipe 154 is connected to the air suction mechanism 13, and the air outlet member 156 is connected to the exhaust duct 20e. The air outlet member 156 can adopt a tee joint or a side joint pipe structure, and the air outlet member 156 and the exhaust duct 20e can adopt a flexible connection or a rigid connection. In this way, the fan assembly 131 can suck air through the air suction port 113a and guide the air to enter the exhaust duct 20e from the air outlet assembly 15'. In this embodiment, the air does not need to pass through the sewage pipe, which reduces mutual interference and makes it easier and faster to discharge the odor. The other structures and working principles of the toilet deodorization device 10 can refer to the first embodiment of the present application, and will not be described here.

[0075] While the present utility model has been described and illustrated with reference to preferred embodiments and several alternatives, it is not limited to the specific descriptions contained in this specification. Other alternative or equivalent components can also be used to practice the present utility model.
