[0028] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other in any way.

[0029] Example 1

[0030] like Figures 1 to 4 As shown, Figures 1 to 4 The figure shows an air duct assembly 1000 for a toilet in a first embodiment. The air duct assembly 1000 includes an air duct body 1, a first one-way component 2, and a second one-way component 3. The first one-way component 2 and the second one-way component 3 are both connected to the air duct body 1.

[0031] The toilet has a pot surface space for accommodating excrement and a configuration space for configuring functional components of the toilet. The functional components can be an electronic cover.

[0032] The air duct body 1 is a thin shell structure. A main air duct 11 and a branch air duct 12 are provided in the air duct body 1. The main air duct 11 is constructed as a long strip of air duct. The main air duct 11 can be arranged horizontally. A first installation space 119 is provided in the main air duct 11. The first installation space 119 is located in the main air duct 11 and is located in the area between the two ends of the main air duct 11. One end of the branch air duct 12 is connected to one end of the main air duct 11, and the other end of the branch air duct 12 is connected to the configuration space of the toilet. The end of the main air duct 11 facing away from the branch air duct 12 is connected to the pot surface space of the toilet.

[0033] The first one-way component 2 includes a first movable member 21 and a first blocking portion 1a. The first movable member 21 is movably disposed on the main air duct 11. The first blocking portion 1a is disposed on the main air duct 11. The first blocking portion 1a is disposed upstream of the first movable member 21 along a first flow direction of fluid flowing toward the pot surface space. When the first movable member 21 is not subjected to pressure from the fluid flowing toward the pot surface space, the first blocking portion 1a engages and seals the main air duct 11.

[0034] The second one-way component 3 includes a second movable member 31 and a second blocking portion 1b. The second movable member 31 is movably disposed on the branch air duct 12. The second blocking portion 1b is disposed on the branch air duct 12. The second blocking portion 1b is disposed upstream of the second movable member 31 along the second flow direction of the fluid flowing toward the configuration space. The second blocking portion 1b engages with the second blocking portion to seal the branch air duct 12 when the second movable member 31 is not subjected to pressure from the fluid flowing toward the configuration space.

[0035] like Figure 7 As shown, when the air duct assembly 1000 is used, a deodorizing medium 6 is placed in the branch air duct 12 of the air duct assembly 1000, a fan 5 is installed in the first installation space 119, and the air duct assembly 1000 is installed on the toilet so that the main air duct 11 is connected to the pot surface space of the toilet, and the branch air duct 12 is connected to the configuration space of the toilet.

[0036] like Figure 5 As shown, when the buttocks need to be dried, the fan 5 is controlled to rotate forward so that the fan 5 conveys airflow in the first direction flowing toward the pot surface space, the first one-way component 2 opens the main air duct 11 under the action of air pressure, and the second one-way component closes the branch air duct 12 under the action of air pressure, and the air flows into the pot surface space to dry the buttocks.

[0037] like Figure 6 As shown, when it is necessary to dehumidify the configuration space or deodorize the pot surface space, the fan 5 is controlled to reverse so that the fan 5 conveys airflow in the second flow direction toward the configuration space, and the second one-way component opens the branch air duct 12 under the action of air pressure, and the first one-way component closes the main air duct 11 under the action of air pressure, and the airflow flows into the configuration space to dehumidify the configuration space or deodorize the pot surface space.

[0038] This air duct assembly 1000 only needs to be provided with one fan 5, and does not need to be provided with an additional motor for changing the wind direction of the fan 5, so the production cost is low. At the same time, this air duct assembly 1000 has a simple and compact structure and occupies less space.

[0039] In an exemplary embodiment, a first air outlet 111 is provided at one end of the main air duct 11, and a second air outlet 112 and a third air outlet 113 are provided at the other end of the main air duct 11. The first air outlet 111, the second air outlet 112, and the third air outlet 113 all penetrate the wall of the main air duct 11. The relative position of the second air outlet 112 and the third air outlet 113 is not limited. For example, the third air outlet 113 can be provided below the second air outlet 112, above the second air outlet 112, or on one side of the second air outlet 112. A first installation space 119 is provided in the area between the two ends of the main air duct 11. The first installation space 119 is located between the first air outlet 111 and the second air outlet 112, and between the first air outlet 111 and the third air outlet 113. The third air outlet 113 of the main air duct 11 is connected to the branch air duct 12. A fourth air port 114 is provided at one end of the branch air duct 12 facing away from the main air duct 11. The branch air duct 12 is used to accommodate the deodorizing medium 6. The first air port 111, the second air port 112, and the fourth air port 114 are all connected to the space outside the air duct body 1.

[0040] The first one-way component 2 is disposed at one end of the main air duct 11 near the branch air duct 12, and may be disposed at the second air outlet 112. The first one-way component 2 is configured to only allow airflow from outside the air duct body 1 into the main air duct 11, and not allow airflow from the main air duct 11 to outside the air duct body 1.

[0041] The second one-way component 3 is disposed between the branch duct 12 and the duct body 1. The second one-way component 3 can connect the branch duct 12 and the duct body 1. The second one-way component 3 can be disposed at the third air outlet 113. The second one-way component 3 is configured to only allow airflow from the main duct 11 to the branch duct 12 to pass through, and not allow airflow from the branch duct 12 to flow into the main duct 11 to pass through.

[0042] The air duct assembly 1000 is installed on the toilet so that the first air port 111 is connected to the pot surface space of the toilet, and the second air port 112 and the fourth air port 114 are connected to the configuration space of the toilet.

[0043] like Figure 5As shown, when the buttocks need to be dried, the fan 5 is controlled to rotate forward so that the fan 5 delivers air to the first air outlet 111. The end of the main air duct 11 near the first air outlet 111 is at positive pressure. The air in the main air duct 11 is output from the air duct body 1 through the first air outlet 111 and blown toward the buttocks to dry the buttocks. Negative pressure is formed at the end of the main air duct 11 near the second air outlet 112. The first one-way component 2 opens under the action of the external atmospheric pressure, and external air is replenished into the main air duct 11 from the second air outlet 112. At the same time, the second one-way component 3 blocks the air in the branch air duct 12 from entering the main air duct 11 through the third air outlet 113, preventing the deodorizing medium 6 in the branch air duct 12 from contaminating the air output from the first air outlet 111 for drying.

[0044] like Figure 6 As shown, when deodorization of the pot surface space is required, the fan 5 is controlled to reverse so that the fan 5 delivers air to the second air port 112 and the third air port 113. The end of the main air duct 11 near the first air port 111 is at negative pressure, and the air in the pot surface space is sucked into the main air duct 11 through the first air port 111. A positive pressure is formed at the end of the main air duct 11 near the second air port 112 and the third air port 113. The second one-way component 3 opens under the action of the air pressure in the main air duct 11, and the air in the main air duct 11 is delivered to the branch air duct 12 through the third air port 113. The deodorizing medium 6 adsorbs odor molecules in the air. The air after deodorization is discharged into the surrounding environment through the fourth air port 114 of the branch air duct 12. At the same time, the first one-way component 2 blocks the air in the main air duct 11 from being discharged into the environment through the second air port 112, preventing direct leakage of odor.

[0045] In an illustrative embodiment, Figure 4As shown, the first one-way component 2 also includes a first support portion 22. The first support portion 22 is connected to the air duct body 1. The first support portion 22 can support the first movable part in a rotatable manner. The first support portion can be a rotating shaft. First mounting holes 1182 are provided on the two opposite side walls of the air duct body 1. The two first mounting holes 1182 are coaxially arranged, and the two ends of the first support portion 22 are respectively inserted into the two first mounting holes 1182. There can be an interference fit between the first support portion 22 and the first mounting holes 1182, so that the first support portion 22 is fixed to the air duct body 1. The orientation of the second air outlet 112 is parallel to the horizontal plane. The first support portion 22 is located at the top of the second air outlet 112. The first support portion 22 extends along the upper edge of the second air outlet 112 and is arranged horizontally. The first movable part 21 is constructed in a plate shape. The shape of the first movable part 21 is the same as that of the second air outlet 112, for example, both are constructed in a rectangular shape. The top end of the first movable member 21 is rotatably connected to the first support portion 22, and the first movable member 21 can freely rotate around the first support portion 22. The width of the first movable member 21 is the same as the width of the second air outlet 112. The first support portion 22 can also support the first movable member 21 in a sliding manner, allowing the first movable member 21 to slide relative to the air duct body 1.

[0046] A first blocking portion 1a is provided at the second air outlet 112. The first blocking portion 1a can be located on the inner side of the lower edge of the second air outlet or a protrusion extending inwardly from the second air outlet 112. A first movable member 21 is provided on the inner side of the second air outlet 112. The first blocking portion 1a limits the first movable member 21 to prevent the first movable member 112 from swinging outwardly from the air duct body 1.

[0047] The length of the first movable member 21 is slightly greater than the height of the second air outlet 112. The first movable member 21 is disposed inside the second air outlet 112. The bottom end of the first movable member 21 can engage the first blocking portion 1a only under the action of gravity, thereby closing the second air outlet 112.

[0048] In this way, when the pressure at one end of the main air duct 11 near the second air outlet 112 is negative, the atmospheric pressure of the surrounding environment can push the first movable member 21 to swing into the main air duct 11, thereby opening the second air outlet 112. When the pressure at one end of the main air duct 11 near the second air outlet 112 is equal to the atmospheric pressure, the air pressure on both sides of the first movable member 21 is equal, and the first movable member 21 closes the second air outlet 112 under the action of gravity. When the pressure at one end of the main air duct 11 near the second air outlet 112 is positive, the first movable member 21 has a tendency to swing outward from the main air duct 11. The first movable member 21 is engaged with the first blocking portion 1a (for example, the inner side of the lower edge of the second air outlet 112), so that the lower edge of the second air outlet 112 limits the first movable member 21, thereby preventing the first movable member 21 from swinging outward and maintaining the state of closing the second air outlet 112. Therefore, the first one-way component 2 can only pass the airflow flowing from the outside of the air duct body 1 to the main air duct 11, and cannot pass the airflow flowing from the main air duct 11 to the outside of the air duct body 1. Moreover, the first one-way component 2 of this structure has a simple structure and low manufacturing cost.

[0049] In another exemplary embodiment, the first one-way component further includes a first force-applying component. The first force-applying component is connected to the first movable member 21 and the air duct body. The first force-applying component can be a spring, a torsion spring, a leaf spring, etc. The first force-applying component is configured to apply a torque to the first movable member 21, causing the first movable member 21 to engage the first blocking portion 1a, thereby closing the second air outlet 112.

[0050] Thus, when the pressure at one end of the main air duct 11 close to the second air outlet 112 is equal to atmospheric pressure, the air pressure on both sides of the first movable member 21 is equal, and the first movable member 21 closes the second air outlet 112 under the action of the first force-applying component.

[0051] In an exemplary embodiment, when the bottom end of the first movable member 21 rests on the inner side of the lower edge of the second air outlet 112 , the angle X between the first movable member 21 and the vertical direction is 0-20°.

[0052] In this way, when the first movable part 21 closes the second air outlet 112, the angle between the first movable part 21 and the vertical direction is small, the pressure difference required to open the first movable part 21 is small, and after the first movable part 21 is opened, the resistance to the airflow passing through the second air outlet 112 is small, thereby increasing the drying air volume.

[0053] In an illustrative embodiment, the second one-way component 3 further includes a second support portion 32. The second support portion 32 is connected to the air duct body 1. The second support portion 32 can support the second movable member 31 in a rotatable manner. The second support portion can be a rotating shaft. Second mounting holes 1183 are provided on two opposite side walls of the air duct body 1. The two second mounting holes 1183 are coaxially arranged, and the two ends of the second support portion 32 are respectively inserted into the two second mounting holes 1183. The second support portion 32 and the second mounting holes 1183 can be an interference fit, thereby fixing the second support portion 32 on the air duct body 1. The orientation of the third air outlet 113 is parallel to the horizontal plane. The second support portion 32 is located at the top of the third air outlet 113. The second support portion 32 extends along the upper edge of the third air outlet 113 and is arranged horizontally. The second movable member 31 is constructed in a plate-like shape. The shape of the second movable member 31 is the same as that of the third air outlet 113, for example, both are constructed in a rectangular shape. The top end of the second movable member 31 is rotatably connected to the second support portion 32, and the second movable member 31 can rotate freely around the second support portion 32. The width of the second movable member 31 is the same as the width of the third air outlet 113. A second blocking portion 1b is provided at the third air outlet 113. The second blocking portion 1b can be the side of the lower edge of the third air outlet 113 facing the branch air duct 12, or the second blocking portion 1b can be a protrusion protruding into the third air outlet 113. The second movable member 31 is provided on the side of the third air outlet 113 facing the branch air duct 12. The second blocking portion 1b limits the second movable member 31 to prevent the second movable member 112 from swinging into the main air duct 11.

[0054] The length of the second movable member 31 is slightly greater than the height of the third air outlet 113. The second movable member 31 is disposed outside the third air outlet 113. Only under the action of gravity can the bottom end of the second movable member 31 engage with the second blocking portion 1b, thereby closing the third air outlet 113.

[0055] In this way, when the pressure at one end of the main air duct 11 near the third air outlet 113 is positive, the air pressure within the main air duct 11 can push the second movable member 31 to swing outward from the main air duct 11, thereby opening the third air outlet 113. When the pressure at one end of the main air duct 11 near the third air outlet 113 is equal to atmospheric pressure, the air pressure on both sides of the second movable member 31 is equal, and the second movable member 31 closes the third air outlet 113 under the action of gravity. When the pressure at one end of the main air duct 11 near the third air outlet 113 is negative, the second movable member 31 has a tendency to swing inward from the main air duct 11, and the second movable member 31 is engaged with the second blocking portion 1b (for example, the lower edge of the third air outlet faces the side of the branch air duct 12), so that the lower edge of the third air outlet 113 limits the second movable member 31, thereby preventing the second movable member 31 from swinging outward and maintaining the state of closing the third air outlet 113. Thus, the second one-way component 3 can only pass airflow from the main air duct 11 to the branch air duct 12, and cannot pass airflow from the branch air duct 12 to the main air duct 11. Moreover, the second one-way component 3 of this structure is simple and has low manufacturing cost. The second support portion 32 can also support the second movable member 31 in a sliding manner, so that the second movable member 31 can slide relative to the air duct body 1.

[0056] In an exemplary embodiment, when the bottom end of the second movable member 31 is placed on the outer side of the lower edge of the third air outlet 113 , the angle Y between the second movable member 31 and the vertical direction is 0-20°.

[0057] In this way, when the second movable part 31 closes the third air outlet 113, the angle between the second movable part 31 and the vertical direction is small, the pressure difference required to open the second movable part 31 is small, and after the second movable part 31 is opened, the resistance to the airflow passing through the third air outlet 113 is small, thereby increasing the deodorizing air volume.

[0058] In another exemplary embodiment, the second one-way component 3 further includes a second force-applying component. The second force-applying component is connected to the second movable member and the air duct body 1. The second force-applying component can be a spring, a torsion spring, a leaf spring, etc. The second force-applying component is used to apply torque to the second movable member, causing the second movable member to tend to approach the second blocking portion 1b, thereby tending to close the third air port 113.

[0059] In this way, when the pressure at one end of the main air duct 11 close to the third air outlet 113 is equal to the atmospheric pressure, the air pressure on both sides of the second movable member is equal, and the second movable member closes the third air outlet under the action of the second force-applying component.

[0060] In one exemplary embodiment, the branch air duct 12 includes a deodorizing chamber 116 and a drainage channel 115. The deodorizing chamber 116 is located below one end of the main air duct 11 near the third air outlet 113. The deodorizing chamber 116 is configured as a rectangular cavity. The deodorizing chamber 116 is separated from the main air duct 11 by a wall. The deodorizing chamber 116 is used to accommodate a deodorizing medium.

[0061] The drainage channel 115 is located on the side of the third air outlet 113 facing away from the main air duct 11 and above the deodorizing chamber 116. The drainage channel 115 extends vertically. Its side connects to the third air outlet 113, and its bottom connects to the top of the deodorizing chamber 116. The third air outlet 113 is connected to the top of the deodorizing chamber 116 through the drainage channel 115. A fourth air outlet 114 is located at the bottom of the deodorizing chamber 116.

[0062] Thus, when the second movable member 31 is opened, it swings into the drainage channel 115. The drainage channel 115 serves as a space for the second movable member 31 to make way for the second movable member 31. At this time, the second movable member 31 is in an inclined state, and the second movable member 31 can guide the airflow output from the third air outlet 113 downward into the deodorizing chamber 116 located below the drainage channel 115, thereby reducing the resistance to the airflow. At the same time, the airflow enters the deodorizing chamber 116 from the top and exits from the bottom of the deodorizing chamber 116. The air can evenly and fully contact the deodorizing medium 6 in the deodorizing chamber 116, and the deodorizing medium 6 has a better deodorizing effect.

[0063] In an illustrative embodiment, the air duct assembly 1000 further includes a rear cover 4. The rear cover 4 can be configured as a flat plate. The shape of the rear cover 4 is the same as that of the fourth air outlet 114, for example, both are rectangular. The rear cover 4 covers the fourth air outlet 114. The rear cover 4 and the main body can be detachably connected. The rear cover 4 and the main body can be detachably connected by a snap-fit ​​connection. The rear cover 4 is provided with a plurality of mesh holes 41, which are through holes extending through the rear cover 4. The plurality of mesh holes 41 can be distributed in a matrix pattern on the rear cover 4.

[0064] Thus, the back cover 4 covering the fourth air vent 114 prevents the deodorizing medium 6 from escaping from the branch air duct 12 through the fourth air vent 114. Furthermore, the plurality of mesh holes 41 provided on the back cover 4 ensure that air can pass through the fourth air vent 114. The back cover 4 is detachably connected to the main body, making it easy to open the back cover 4 to replace the deodorizing medium 6.

[0065] In an exemplary embodiment, the main air duct 11 is in a straight strip shape. The main air duct 11 is configured as a straight strip channel so that the airflow does not need to change direction when flowing along the main air duct 11, thereby reducing airflow resistance and increasing air volume.

[0066] In an exemplary embodiment, the cross-sectional area of ​​the main air duct 11 gradually decreases from the first installation space 119 to the first air outlet 111 .

[0067] In the drying mode, the air flow flows from the fan 5 to the first air outlet 111. The closer to the first air outlet 111, the smaller the cross-sectional area of ​​the main air duct 11 and the greater the air pressure, thereby increasing the wind speed of the air flow output from the first air outlet 111, improving the air supply distance and drying speed.

[0068] In an illustrative embodiment, the air duct body 1 includes an upper shell 117 and a lower shell 118. The lower shell 118 is located below the upper shell 117. The lower shell 118 is connected to the upper shell 117. The upper shell 117 and the lower shell 118 are connected by a snap-fit ​​connection. For example, a plurality of female buckles 1171 are provided on the side of the upper shell 117 close to the lower shell 118, and a plurality of male buckles 1181 are provided on the side of the lower shell 118 close to the upper shell 117. The plurality of female buckles 1171 are respectively coupled with the plurality of male buckles 1181, thereby fixing the upper shell 117 and the lower shell 118 together. The upper shell 117 and the lower shell 118 enclose the main air duct 11. The branch air duct 12 is located on the lower shell 118. The first one-way component 2 and the second one-way component 3 are both mounted on the lower shell 118.

[0069] In this way, before the upper shell 117 and the lower shell 118 are assembled together, the first one-way component 2, the second one-way component 3 and the fan 5 can be installed on the lower shell 118 first, and then the upper shell 117 and the lower shell 118 are assembled together, which makes it easier to install the first one-way component 2, the second one-way component 3 and the fan 5 on the air duct body 1.

[0070] like Figure 7 As shown, this embodiment further proposes a deodorizing and drying device, which includes the above-mentioned air duct assembly 1000, the above-mentioned fan 5 and the above-mentioned deodorizing medium 6.

[0071] Example 2

[0072] like Figure 8 As shown, Figure 8 A deodorizing and drying device 100a in Example 2 is shown. The deodorizing and drying device 100a in Example 2 differs from the deodorizing and drying device 100 in Example 1 primarily in the fan. To avoid redundancy, only the differences between the two are described below.

[0073] The deodorizing and drying device 100a includes an air duct assembly 1000, a deodorizing medium 6, a heating module 7, a first fan 21b, and a second fan 22b. The air duct assembly 1000 includes an air duct body 1, a first one-way component 2, and a second one-way component 3.

The first installation space 119 is located in the main air duct 11 and is located in the area between the two ends of the main air duct 11. One end of the branch air duct 12 is connected to one end of the main air duct 11, and the other end of the branch air duct 12 is connected to the configuration space of the toilet. The end of the main air duct 11 facing away from the branch air duct 12 is connected to the pot surface space of the toilet.

[0075] A first air outlet 111 is provided at one end of the main air duct 11, and a second air outlet 112 and a third air outlet 113 are provided at the other end of the main air duct 11. The first air outlet 111, the second air outlet 112, and the third air outlet 113 all penetrate the wall of the main air duct 11. The relative position between the second air outlet 112 and the third air outlet 113 is not limited. For example, the third air outlet 113 can be provided below the second air outlet 112, above the second air outlet 112, or on one side of the second air outlet 112. A first installation space 119 is provided in the area between the two ends of the main air duct 11. The first installation space 119 is located between the first air outlet 111 and the second air outlet 112 and between the first air outlet 111 and the third air outlet 113. The third air outlet 113 of the main air duct 11 is connected to the branch air duct 12. A fourth air port 114 is provided at one end of the branch air duct 12 facing away from the main air duct 11. The branch air duct 12 accommodates the deodorizing medium 6. The first air port 111, the second air port 112, and the fourth air port 114 are all connected to the space outside the air duct body 1.

[0076] The first one-way component 2 includes a first movable member 21 and a first blocking portion 1a. The first movable member 21 is movably disposed on the main air duct 11. The first blocking portion 1a is disposed on the main air duct 11. The first blocking portion 1a is disposed upstream of the first movable member 21 along a first flow direction of fluid flowing toward the pot surface space. When the first movable member 21 is not subjected to pressure from the fluid flowing toward the pot surface space, the first blocking portion 1a engages and seals the main air duct 11.

[0077] The second one-way component 3 includes a second movable member 31 and a second blocking portion 1b. The second movable member 31 is movably disposed on the branch air duct 12. The second blocking portion 1b is disposed on the branch air duct 12. The second blocking portion 1b is disposed upstream of the second movable member 31 along the second flow direction of the fluid flowing toward the configuration space. The second blocking portion 1b engages with the second blocking portion to seal the branch air duct 12 when the second movable member 31 is not subjected to pressure from the fluid flowing toward the configuration space.

[0078] The first fan 21b and the second fan 22b are both disposed within the first installation space 119 of the main air duct 11. The first fan 21b and the second fan 22b are arranged sequentially along the main air duct 11. The first fan 21b delivers air to one end of the main air duct 11, and the second fan 22b delivers air to the other end of the main air duct 11. In this embodiment, the first fan 21b can deliver air to the first air outlet 111. The second fan 22b can deliver air to the second air outlet 112 and the fourth air outlet 113. The first fan 21b and the second fan 22b do not operate simultaneously.

[0079] like Figure 9 As shown, when the buttocks need to be dried, the first fan 21b is controlled to deliver airflow in the first direction toward the pot surface space, the first one-way component 2 opens the main air duct 11 under the action of air pressure, and the second one-way component closes the branch air duct 12 under the action of air pressure, and the airflow flows into the pot surface space to dry the buttocks.

[0080] like Figure 10 As shown, when it is necessary to dehumidify the configuration space or deodorize the pot surface space, the second fan 22b is controlled to deliver airflow to the second flow direction of the configuration space, the second one-way component opens the branch air duct 12 under the action of air pressure, and the first one-way component closes the main air duct 11 under the action of air pressure, and the airflow flows into the configuration space to dehumidify the configuration space or deodorize the pot surface space.

[0081] The air duct assembly does not need to be equipped with an additional motor for changing the wind direction, and thus has a low production cost. Furthermore, the air duct assembly has a simple and compact structure and occupies a small space.

[0082] Example 3

[0083] like Figure 11 As shown, the third embodiment proposes a deodorizing and drying device 100b. The difference between the deodorizing and drying device 100 in the third embodiment and the deodorizing and drying device 100 in the first embodiment lies in the structure of the one-way component. To avoid redundancy, the following mainly introduces the difference between the two.

[0084] The deodorizing and drying device 100b includes an air duct assembly, a fan 5, a heating module 7, and a deodorizing medium 6. The air duct assembly includes an air duct body 1 and a third one-way component.

[0085] The air duct body 1 is a thin shell structure. A main air duct 11 and a branch air duct 12 are provided in the air duct body 1. The main air duct 11 is constructed as a long strip of air duct. The main air duct 11 can be arranged horizontally. A first installation space 119 is provided in the main air duct 11. The first installation space 119 is located in the main air duct 11 and is located in the area between the two ends of the main air duct 11. One end of the branch air duct 12 is connected to one end of the main air duct 11, and the other end of the branch air duct 12 is connected to the configuration space of the toilet. The end of the main air duct 11 facing away from the branch air duct 12 is connected to the pot surface space of the toilet.

[0086] A first air outlet 111 is provided at one end of the main air duct 11, and a second air outlet 112 and a third air outlet 113 are provided at the other end of the main air duct 11. The first air outlet 111, the second air outlet 112, and the third air outlet 113 all penetrate the wall of the main air duct 11. The relative position between the second air outlet 112 and the third air outlet 113 is not limited. For example, the third air outlet 113 can be provided below the second air outlet 112, above the second air outlet 112, or on one side of the second air outlet 112. A first installation space 119 is provided in the area between the two ends of the main air duct 11. The first installation space 119 is located between the first air outlet 111 and the second air outlet 112 and between the first air outlet 111 and the third air outlet 113. The third air outlet 113 of the main air duct 11 is connected to the branch air duct 12. A fourth air port 114 is provided at one end of the branch air duct 12 facing away from the main air duct 11. The branch air duct 12 contains the deodorizing medium 6. The first air port 111 is connected to the pot surface space of the toilet, and the second air port 112 and the fourth air port 114 are both connected to the configuration space of the toilet.

[0087] The third one-way component 3a is connected to the air duct body 1. The third one-way component 3a includes a third movable member 31a, a first blocking portion 32a, a second blocking portion 33a, and a third rotating shaft 34a. The third movable member 31a is movably disposed relative to the air duct body 1. The third movable member 31a includes a first movable portion 311a and a second movable portion 312a. The first movable portion 311a and the second movable portion 312a can both be flat plates. One end of the first movable portion 311a is connected to one end of the second movable portion 312a. The first movable portion 311a and the second movable portion 312a can form an angle between them. The intersection of the first movable portion 311a and the second movable portion 312a is connected to the air duct body 1 via the third rotating shaft 34a, forming a rotational connection between the third movable member 31a and the air duct body 1. The third rotating shaft 34a is disposed between the second air outlet 112 and the third air outlet 113, with both ends of the third rotating shaft 34a connected to opposite side walls of the air duct body 1. The first movable portion 311a is positioned upstream of the second air port 112, along the direction of air flowing from the second air port 112 into the main air duct. The second movable portion 312a is positioned upstream of the third air port 113, along the direction of air flowing from the third air port 113 into the main air duct. The area of ​​the first movable portion 311a is larger than the cross-sectional area of ​​the second air port 112. The first movable portion 311a can rotate to cover the second air port 112, thereby closing the second air port 112. The area of ​​the second movable portion 312a is larger than the cross-sectional area of ​​the third air port 113. The second movable portion 312a can rotate to cover the third air port 113, thereby closing the third air port 113. The area of ​​the second movable portion 312a is larger than the cross-sectional area of ​​the third air port 113.

[0088] The first blocking portion 32a is disposed downstream of the first movable portion 311a along the direction of air flowing from the second air outlet 112 into the main air duct. The second blocking portion 33a is disposed upstream of the second movable portion 312a along the direction of air flowing from the first air outlet 111 into the main air duct. The first blocking portion 32a and the second blocking portion 33a may be configured as protrusions, and the first blocking portion 32a and the second blocking portion 33a may be disposed at the top of the second air outlet 112 and the bottom of the third air outlet 113, respectively.

[0089] The third movable part 31a is configured so that when the fan 5 is not working and the fan 5 is delivering air flow toward the first air outlet 111, the second movable part is not subjected to the pressure of the fluid flowing toward the configuration space, and the third movable part 31a rotates to the second movable part 312a to engage with the second blocking part 33a to block the wind from flowing into the main air duct 11 from the fourth air outlet 114 and the third air outlet 113 in sequence. At the same time, the first movable part 311a is separated from the first blocking part 32a to open the first air outlet 111 so that the wind can flow into the main air duct 11 through the second air outlet 112, flow toward the first air outlet 111, and finally flow out from the first air outlet 111.

[0090] The third movable part 31a is configured so that when the fan 5 transports air flow in the direction of the second air outlet 112 and the third air outlet 113, the second movable part is subjected to the pressure of the fluid flowing into the configuration space, and the third movable part 31a rotates to the first movable part 311a to engage the first blocking part 32a to block the wind from flowing from the second air outlet 112 into the main air duct 11, and the second movable part 312a is separated from the second blocking part 33a to open the third air outlet 113 so that the wind can flow from the first air outlet 111 to the fourth air outlet 114.

[0091] In this way, when the fan 5 delivers air toward the first air port 111, the second movable portion 312a is not affected by the pressure of the fluid flowing into the configuration space, the third air port 113 is covered and closed by the second movable portion 312a, the first movable portion 311a moves away from the second air port 112, opening the second air port 112, and the air flows through the second air port 112 toward the first air port 111. The fan 5 delivers air toward the second air port 112 and the fourth air port 114. The second movable portion 312a is affected by the pressure of the fluid flowing into the configuration space, the second air port 112 is covered and closed by the first movable portion 311a, the second movable portion 312a moves away from the third air port 113, opening the third air port 113, and the air flows sequentially through the first air port 111 and the third air port 113 to the fourth air port 114.

[0092] This air duct assembly only needs to be provided with one fan 5, and does not need to be provided with an additional motor for changing the wind direction of the fan 5, so the production cost is low. At the same time, this air duct assembly has a simple and compact structure and occupies less space.

[0093] In an exemplary embodiment, the third air outlet 113 is disposed below the second air outlet 112. The third movable member 31a is configured such that, under the action of gravity, the second movable portion 312a tends to rotate toward the second blocking portion 33a, so that when the fan 5 is not operating and the fan 5 is delivering airflow toward the first air outlet 111, that is, when the second movable portion 312a is not subjected to the pressure of the fluid flowing into the configuration space, the second movable portion 312a closes the third air outlet 113, and the first movable portion 311a opens the second air outlet 112. When the second blocking portion 33a blocks the second movable portion 312a, the first movable portion 311a tilts upward in a direction away from the second air outlet 112. The center of gravity of the third movable member 31a and the second blocking portion 33a are located on opposite sides of the third rotating shaft 34a, so that the gravity applied to the third movable member 31a can be converted into power to drive the third movable member 31a to rotate toward the second blocking portion 33a.

[0094] In this way, when the fan 5 is not working and the fan 5 is delivering airflow toward the first air port 111 , the second movable portion 312 a of the third movable member 31 a can maintain a state of closing the third air port 113 .

[0095] In an exemplary embodiment, the cross-sectional area of ​​the third air port 113 is set to be larger than the cross-sectional area of ​​the second air port 112 , and the area of ​​the second movable portion 312 a is larger than the area of ​​the first movable portion 311 a .

[0096] In this way, the fan 5 supplies air to the second air outlet 112 and the third air outlet 113. Since the second movable part 312a has a larger area than the first movable part 311a, the second movable part 312a is subjected to a greater wind pressure. The second movable part 312a can open the third air outlet 113 under the action of the wind pressure, and make the first movable part 311a close the second air outlet 112, thereby realizing air intake through the first air outlet 111 and air discharge through the fourth air outlet 114.

[0097] Example 4

[0098] like Figure 14 As shown, the fourth embodiment proposes a deodorizing and drying device 100d. The difference between the deodorizing and drying device 100d of the fourth embodiment and the deodorizing and drying device 100 of the first embodiment lies mainly in the different structure of the air duct body and the different position of the fan within the air duct body. To avoid redundant description, the following mainly introduces the differences between the two.

[0099] The deodorizing and drying device 100d includes an air duct assembly 1000a, a fan 5, a heating module 7 and a deodorizing medium 6.

[0100] The air duct assembly 1000a includes an air duct body 1c, a fourth one-way component 9a, and a fifth one-way component 9b.

[0101] The air duct body 1c is a thin shell structure. A main air duct 10c is disposed within the air duct body 1c. The main air duct 10c may be in the form of a straight strip. A fifth air port 111c and a sixth air port 112c are disposed on the wall of the main air duct 10c. The fifth air port 111c and the sixth air port 112c may be disposed at opposite ends of the main air duct 10c. The fifth air port 111c is connected to the pot surface space of the toilet, and the sixth air port 112c is connected to the configuration space of the toilet. The main air duct 10c is connected to the pot surface space 301 of the seat body through the fifth air port 111c, and is connected to the configuration space 302 of the seat body through the sixth air port 112c.

[0102] A partition 11c and a branch channel 12c are provided in the main air duct 10c. The partition 11c is located between the fifth air outlet 111c and the sixth air outlet 112c, and the partition 11c divides the main air duct 10c into two sections. The partition 11c can be constructed as a plate-like structure. A seventh air outlet 113c and an eighth air outlet 114c are provided on the partition 11c. The seventh air outlet 113c and the eighth air outlet 114c both pass through the partition 11c, and the relative positions of the seventh air outlet 113c and the eighth air outlet 114c are not limited. The seventh air outlet 113c can be provided above the eighth air outlet 114c. The branch channel 12c is provided in the main air duct 10c and is located on the side of the partition 11c close to the sixth air outlet 112c. One end of the branch channel 12c is connected to the eighth air outlet 114c. The fan is provided between the partition 11c and the sixth air outlet 112c. The branch channel 12c extends from the eighth air port 114c to the fan 5 and the sixth air port 112c, and one end of the branch channel 12c facing away from the eighth air port 114c faces the fan 5. The heating module 7 is disposed between the partition 11c and the fifth air port 111c.

[0103] The air treatment device 100d further includes a deodorizing medium 6. The deodorizing medium 6 is disposed in the branch flow passage 12c.

[0104] The fourth one-way component 9a is disposed at the seventh air outlet 113c. The fourth one-way component 9a includes a fourth movable member 91a and a fourth blocking portion 93a. The fourth blocking portion 93a is disposed upstream of the fourth movable member 91a along the direction of fluid flow from the seventh air outlet 113c to the fifth air outlet 111c. The fourth blocking portion 93a may be a protrusion disposed at the lower edge of the seventh air outlet 113c. The fourth movable member 91a is movably disposed relative to the air duct body 1c. For example, the fourth movable member 91a may be rotatable or slidable relative to the air duct body 1c. In this embodiment, the fourth one-way component 9a further includes a fourth rotating shaft. The ends of the fourth rotating shaft 92a are connected to opposite side walls of the air duct body 1c and are located above the seventh air outlet 113c. The fourth movable member 91a is configured as a flat plate structure parallel to the fourth rotating shaft 92a. The top end of the fourth movable member 91a is connected to the fourth rotating shaft 92a. The fourth movable member 91a is rotatably connected to the air duct body 1c via the fourth rotating shaft 92a. The fourth movable member 91a is configured so that when the fan 5 blows air toward the sixth air port, it is pressurized by the fluid flowing into the arrangement space and engages the fourth blocking portion 93a, thereby closing the seventh air port 113c. When the fan 5 blows air toward the fifth air port 111c, the fourth movable member 91a is pressurized by the fluid flowing into the pot surface space and opens the seventh air port 113c, allowing air to flow through the sixth and seventh air ports 112c and 113c toward the fifth air port 111c.

[0105] The fifth one-way component 9b is arranged at the eighth air outlet 114c. The fifth one-way component 9b includes a fifth movable component 91b and a fifth blocking portion 93b. The fifth blocking portion 93b is arranged upstream of the fifth movable component 91b along the direction of fluid flowing from the eighth air outlet 114c to the sixth air outlet 112c. The fifth blocking portion 93b can be a protrusion arranged at the lower edge of the eighth air outlet 114c. The fifth movable component 91b is movably arranged relative to the air duct body 1c, and the fifth movable component 91b can, for example, be rotatable or slidable relative to the air duct body 1c. In this embodiment, the fifth one-way component 9b also includes a fifth rotating shaft 92b, and both ends of the fifth rotating shaft 92b are connected to the opposite side walls of the air duct body 1c, and are located above the eighth air outlet 114c. The fifth movable member 91b is configured as a flat plate structure parallel to the fifth rotating shaft 92b. The top end of the fifth movable member 91b is connected to the fifth rotating shaft 92b. The fifth movable member 91b is rotatably connected to the air duct body 1c via the fifth rotating shaft 92b. The fifth movable member 91b is configured such that when the fan 5 delivers air to the fifth air port 111c, the pressure of the fluid flowing into the pot surface space causes the fifth movable member 91b to engage the fifth blocking portion 93b to close the eighth air port 114c. When the fan 5 delivers air to the sixth air port, the pressure of the fluid flowing into the configuration space causes the fifth movable member 91b to open the eighth air port 114c, allowing air to flow through the fifth air port 111c, the eighth air port 114c, and the deodorizing medium 6 to the sixth air port 112c.

[0106] like Figure 15 As shown, in drying mode, heating module 7 heats air, and fan 5 delivers air to fifth air port 111c. Driven by air pressure, fourth one-way component 9a opens seventh air port 113c, while fifth one-way component 9b closes eighth air port 114c. Air then flows sequentially through sixth air port 112c, fan 5, seventh air port 113c, and heating module 7 before exiting fifth air port 111c. The air exiting fifth air port 111c can dry the buttocks. Furthermore, since fifth one-way component 9b closes eighth air port 114c, it prevents the deodorizing medium 66 in branch channel 12c from contaminating the drying air exiting fifth air port 111c.

[0107] like Figure 16 As shown, in the deodorization working mode, the heating module 7 does not heat the air, and the fan 5 delivers airflow to the sixth air outlet 112c. Driven by the air pressure, the fourth one-way component 9a closes the seventh air outlet 113c, and the fifth one-way component 9b opens the eighth air outlet 114c. The airflow flows through the fifth air outlet 111c, the eighth air outlet 114c, the branch channel 12c, the fan 5 in sequence, and is finally output from the sixth air outlet 112c. When the air flows through the branch channel 12c, the deodorization medium 66 absorbs odor molecules in the air, and the air after deodorization is discharged from the sixth air outlet 112c.

[0108] like Figure 16As shown, in the dehumidification working mode, the heating module 7 heats the air, and the fan 5 delivers air flow to the sixth air outlet 112c. Driven by the air pressure, the fourth one-way component 9a closes the seventh air outlet 113c, and the fifth one-way component 9b opens the eighth air outlet 114c. The air flows through the fifth air outlet 111c, the heating module 7, the eighth air outlet 114c, the branch channel 12c, and the fan 5 in sequence, and is finally output from the sixth air outlet 112c. The air is heated when flowing through the heating module 7 and deodorized when flowing through the branch channel 12c. The hot air discharged from the sixth air outlet 112c can dehumidify the electrical components on the functional components 200 in the configuration space 302.

[0109] The air duct assembly 1000a does not need to be equipped with an additional motor for changing the wind direction, and thus has a low production cost. Furthermore, the air duct assembly 1000a has a simple and compact structure and occupies a small space.

[0110] In the description of the present invention, it should be noted that the terms "upper", "lower", "one side", "the other side", "one end", "the other end", "side", "relative", "four corners", "periphery", "'mouth'-shaped structure", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing "this" utility model and simplifying the description, and do not indicate or imply that the structure referred to has a specific orientation, is constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.
