[0025] 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.

[0026] like Figure 1 、 4 As shown, Figure 1 、 4 A drying device 100 in an embodiment of the present application is shown, which includes an air duct assembly 10, a deodorizing medium, a heating module 7, a fan module 5, and a control module 8. The deodorizing medium 6, the heating module 7, and the fan module 5 are all mounted on the air duct assembly 10.

[0027] like Figure 2 、 3 As shown in Figures 4 and 5, the air duct assembly 10 includes a housing 1 and a first one-way valve 2. The first one-way valve 2 is connected to the housing 1.

[0028] The housing 1 has a thin shell structure. It includes an upper shell 117 and a lower shell 118. The lower shell 118 is located below the upper shell 117. One of the upper shell 117 and the lower shell 118 is provided with a mounting opening 101, and the other of the upper shell 117 and the lower shell 118 covers the mounting opening 101. The lower shell 118 is connected to the upper shell 117. The upper shell 117 and the lower shell 118 can be connected by a snap-fit ​​connection. For example, a plurality of female snaps 1171 are provided on the side of the upper shell 117 near the lower shell 118, and a plurality of male snaps 1181 are provided on the side of the lower shell 118 near the upper shell 117. The plurality of female snaps 1171 are respectively coupled with the plurality of male snaps 1181, thereby securing 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 first air outlet 111, and the second air outlet 112. The main air duct 11 is constructed as an elongated air duct. The main air duct 11 can be arranged horizontally. The first air outlet 111 is arranged at the end of one end of the main air duct 11, and the second air outlet 112 and the third air outlet 113 are both arranged at the end of the other end of the main air duct 11. The installation opening 101 is connected to the main air duct 11. The installation opening 101 can be arranged at the top of the main air duct 11. The installation opening 101 is used to allow the fan module 5, the heating module 7 and the first one-way valve 2 to pass through so that the fan module 5, the heating module 7 and the first one-way valve 2 can be installed in the main air duct 11.

[0029] The fan module 5, heating module 7, and first one-way valve 2 are all disposed within the main air duct 11. The fan module 5 may be an axial flow fan module. The heating module 7 is used to heat air. The first one-way valve 2 is used to limit the flow direction of the fluid within the main air duct.

[0030] In this way, before the upper shell 117 and the lower shell 118 are assembled together, the first one-way valve 2, the fan module 5 and the heating module 7 can be installed into the main air duct from the installation opening 101, and then the upper shell 117 and the lower shell 118 can be assembled together, which makes it easier to install the first one-way valve 2, the heating module 7 and the fan module 5 on the shell 1.

[0031] In an exemplary embodiment, the installation opening 101 is provided at the top of the lower shell 118, and the upper shell 117 covers the installation opening 101. The lower shell 118 is provided with a deodorizing chamber 12, a third air port 113, and a fourth air port 114.

[0032] The first air vent 111 and the second air vent 112 all extend through the wall of the main air duct 11. The relative position of the second air vent 112 and the third air vent 113 is not limited. For example, the third air vent 113 can be located below, above, or to the side of the second air vent 112. A first installation space 119 and a second installation space 120 are provided within the main air duct 11. The first installation space 119 is located in the area between the two ends of the main air duct 11. The first installation space 119 is used to install the fan module 5. Thus, the first installation space 119 is located between the first air vent 111 and the second air vent 112, and between the first air vent 111 and the third air vent 113. The second installation space 120 is located between the first installation space 119 and the first air outlet 111. The second installation space 120 is used to install the heating module 7. The third air vent 113 of the main air duct 11 is connected to the deodorizing chamber 12. A fourth air port 114 is provided on the wall of the deodorizing chamber 12. The deodorizing chamber 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 housing 1.

[0033] The air duct assembly also includes a second one-way valve 3. Both the first one-way valve 2 and the second one-way valve 3 are mounted on the lower housing 118. The first one-way valve 2 is positioned on the lower housing 118 near the second air port 112. The first one-way valve 2 is configured to allow only airflow from outside the housing 1 into the main air duct 11, and not from the main air duct 11 out of the housing 1.

[0034] The second one-way valve 3 is disposed on the lower housing 118 near the third air port 113. The second one-way valve 3 is configured to only allow airflow from the main air duct 11 to the deodorizing chamber 12 to pass through, but not from the deodorizing chamber 12 to the main air duct 11.

[0035] The deodorizing medium 6 can be constructed as a block-shaped porous structure and disposed within the deodorizing chamber 12 of the air duct assembly 10. The deodorizing medium 6 is used to filter out odor molecules from the air. The deodorizing medium 6 can include at least one of activated carbon, NaOH, NaOCl, a natural plant extract deodorant, and a bio-enzyme deodorant. The activated carbon is provided with micropores that adsorb odor molecules. Without destroying its original structure, the activated carbon can be heated to remove odor molecules adsorbed within the micropores, thereby restoring its adsorption properties. NaOH and NaOCl can adsorb H2S molecules in the air, achieving the purpose of deodorization. Natural plant extract deodorants have antibacterial, bactericidal, and deodorizing properties, and are effective in decomposing and removing odors such as ammonia and hydrogen sulfide. Bio-enzyme deodorants are primarily formulated with plant enzymes, enzyme-rich ingredients, and antibacterial factors. They can quickly eliminate environmental odors and effectively inhibit the growth of pathogens.

[0036] The fan module 5 is installed in the first installation space 119. The fan module 5 can be a fan that can selectively deliver air toward one of the two ends of the main air duct. The fan blades of the fan can rotate forward and reverse, allowing the fan module 5 to deliver air in two different directions. Forward rotation of the fan module can cause the fan module 5 to deliver air to the first air outlet 111, while reverse rotation of the fan module can cause the fan module 5 to deliver air to the second air outlet 112 and the third air outlet 113.

[0037] The heating module 7 can convert electrical energy into heat and transfer the heat to the air. The heating module 7 is disposed in the second installation space 120.

[0038] The control module 8 serves as the logic control unit for the drying device 100. The control module 8 can be a single-chip microcomputer or a microcomputer. The control module 8 is located outside the air duct assembly 10. The fan module 5 is provided with a first wire 51, which can be connected to the control module 8 through a wire hole in the housing. The heating module 7 is provided with a second wire 71, which can be connected to the control module 8 through a wire hole in the housing.

[0039] like Figure 7 As shown, the drying device 100 is installed on the toilet so that the first air outlet 111 is connected to the pot surface space of the toilet, and the second air outlet 112 and the fourth air outlet 114 are both connected to the configuration space of the functional components configured in the toilet.

[0040] like Figure 5As shown, when the buttocks need to be dried, the control module 8 controls the heating module 7 to heat the air and controls the fan module 5 to deliver airflow to the first air outlet 111. The end of the main air duct 11 near the first air outlet 111 is positive pressure, and the airflow is heated into hot air flow when flowing through the heating module 7. The hot air flow in the main air duct 11 is then output from the housing 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 valve 2 opens under the action of atmospheric pressure, and the air in the configuration space is replenished into the main air duct 11 from the second air outlet 112. At the same time, the second one-way valve 3 blocks the air in the deodorization chamber 12 from entering the main air duct 11 through the third air outlet 113, preventing the deodorization medium 6 in the deodorization chamber 12 from contaminating the air output from the first air outlet 111 for drying.

[0041] like Figure 6 As shown, when deodorization of the pot surface space is required, the control module 8 controls the heating module 7 to not heat the air and controls the fan module 5 to deliver 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. The air in the pot surface space is sucked into the main air duct 11 through the first air port 111, forming a positive pressure 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 valve 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 deodorization chamber 12 through the third air port 113. The deodorizing medium 6 absorbs odor molecules in the air. The deodorized air is then discharged into the configuration space through the fourth air port 114 of the deodorization chamber 12. At the same time, the first one-way valve 2 prevents the air in the main air duct 11 from being discharged into the configuration space through the second air port 112, preventing direct leakage of odor.

[0042] like Figure 6 As shown, when it is necessary to dehumidify the electrical components around the third air outlet 113, the control module 8 controls the heating module 7 to heat the air and controls the fan module 5 to transport air to the second air outlet 112 and the third air outlet 113. The end of the main air duct 11 close to the first air outlet 111 is at negative pressure, and the air in the pot surface space is sucked into the main air duct 11 from the first air outlet 111. The air is heated into hot air flow by the heating module 7 when flowing through the heating module 7. At the same time, positive pressure is formed at one end of the main air duct 11 close to the second air outlet 112 and the third air outlet 113. The second one-way valve 3 opens under the action of the air pressure of the main air duct 11, and the hot air flow in the main air duct 11 is transported to the deodorization chamber 12 through the third air outlet 113 and the deodorization medium 6 adsorbs odor molecules in the air. The hot air flow after removing the odor is discharged from the fourth air outlet 114 of the deodorization chamber 12 into the configuration space, thereby dehumidifying the electrical components around the third air outlet 113. At the same time, the first one-way valve 2 blocks the air in the main air duct 11 from being discharged into the configuration space through the second air port 112 , thereby preventing direct leakage of odor.

[0043] This drying device 100 only requires one fan module 5, and the fan of this fan module 5 can deliver air in two directions. No additional motor is required to change the airflow direction of the fan module 5, resulting in low production costs. Furthermore, this drying device 100 has a simple and compact structure, occupying a small space. The fan module 5 can switch the airflow direction between drying and deodorizing by simply changing the direction of its fan blades. The switching time between the drying and deodorizing functions of the drying device 100 is very short.

[0044] Before the upper shell 117 and the lower shell 118 are assembled together, the first one-way valve 2, the second one-way valve 3, the fan module 5 and the heating module 7 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 valve 2, the second one-way valve 3, the heating module 7 and the fan module 5 on the shell 1.

[0045] In an illustrative embodiment, a mounting bracket 1184 is provided in the main air duct 11 of the housing 1. The mounting bracket 1184 can be constructed in a frame shape. A ventilation hole 1185 is provided in the middle of the mounting bracket 1184, and the ventilation hole 1185 is a circular through hole. The fan module 5 includes a fan, which includes a housing 52 and a fan blade 53. The housing 52 is provided with a first air duct 521, and the extension direction of the first air duct 521 is the same as the extension direction of the main air duct 11. One end of the first air duct 521 of the housing 52 is connected to the ventilation hole 1185 of the mounting bracket 1184. The fan blade 53 is provided in the first air duct 521 of the housing 52, and the rotating shaft of the fan blade 53 is coaxially arranged with the first air duct 521. The housing 52 of the fan module 5 and the mounting bracket 1184 can be connected by screws 9.

[0046] In this way, the fan module 5 can be firmly fixed on the housing 1 by screw connection with the mounting bracket 1184.

[0047] In an illustrative embodiment, four through holes 522 are provided on the casing 52, and the four through holes 522 are evenly distributed around the first air duct 521 of the casing 52. Four screw holes 1186 are provided on the mounting frame 1184. The four through holes 522 on the casing 52 are coaxially arranged with the four screw holes 1186 on the mounting frame 1184, and four screws 9 are provided. The four screws 9 respectively pass through the four through holes 522 on the casing 52 and are screwed into the four screw holes 1186 on the mounting frame 1184.

[0048] The fan module 5 is connected to the mounting bracket 1184 using four screws 9 so that the fan module 5 can be mounted more securely.

[0049] In an illustrative embodiment, the heating module 7 includes a shell 72 and an electric heating element 73. The shell 72 can be constructed in a cylindrical shape. A second air duct 721 is provided in the shell 72. The extension direction of the second air duct 721 is the same as the extension direction of the main air duct 11. The two ends of the second air duct 721 are respectively connected to the first air outlet 111 and the fan module 5. There can be multiple second air ducts 721, and multiple second air ducts 721 are arranged in parallel. The electric heating element 73 is arranged in the second air duct 721. The electric heating element 73 can be an electric heating wire, a silicon-molybdenum rod, a silicon-carbon rod or a ceramic heating element. The electric heating element 73 can convert electrical energy into thermal energy. There can be multiple electric heating elements 73, and the multiple electric heating elements 73 are arranged in sequence along the extension direction of the second air duct 721.

[0050] In this way, the plurality of electric heating elements 73 can heat the airflow flowing through the second air duct 721 of the shell 72 at the same time, so that the airflow is heated up quickly and no cold air is output to the human body to make the human body feel uncomfortable.

[0051] In an illustrative embodiment, the first one-way valve 2 includes a first movable member 21 and a first blocking portion 1a. The first movable member 21 is movably disposed on the lower shell 118. The first movable member 21 can be slidably or rotatably connected to the lower shell. The first blocking portion 1a is disposed on the main air duct 11. The first blocking portion 1a is fixedly connected to the lower shell 118. The first movable member 21 is disposed upstream of the first movable member 21 along the first flow direction of the fluid flowing from the second air port 112 to the first air port 111, so as to engage the first blocking portion 1a to close the second air port 112 when the first movable member 21 is not subjected to the pressure of the fluid flowing to the first air port 111.

[0052] The second one-way valve 3 includes a second movable member 31 and a second blocking portion 1b. The second movable member 31 is movably disposed on the lower housing 118. The first movable member 21 can be slidably or rotatably connected to the lower housing 118. The second blocking portion 1b is fixedly connected to the lower housing 118. The second blocking portion 1b is disposed upstream of the second movable member 31 along the second flow direction of the fluid flowing from the first air port 111 to the fourth air port 114, so as to engage the second blocking portion 1b to close the third air port 113 when the second movable member 31 is not subjected to pressure from the fluid flowing toward the fourth air port 114.

[0053] In an illustrative embodiment, Figure 4As shown, the first one-way valve 2 also includes a first rotating shaft 22. The first rotating shaft 22 is connected to the housing 1. First mounting holes 1182 are provided on two opposing side walls of the housing 1. The two first mounting holes 1182 are coaxially arranged, and the ends of the first rotating shaft 22 are respectively inserted into the two first mounting holes 1182. The first rotating shaft 22 and the first mounting holes 1182 can be an interference fit, thereby fixing the first rotating shaft 22 to the housing 1. The second air outlet 112 is oriented parallel to the horizontal plane. The first rotating shaft 22 is located at the top of the second air outlet 112. The first rotating shaft 22 extends along the upper edge of the second air outlet 112 and is arranged horizontally. The first movable member 21 is plate-shaped. The shape of the first movable member 21 is the same as that of the second air outlet 112, for example, both are rectangular. The top end of the first movable member 21 is rotatably connected to the first rotating shaft 22, and the first movable member 21 can rotate freely about the first rotating shaft 22. The width of the first movable member 21 is the same as that of the second air outlet 112. 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. Only under the action of gravity can the bottom end of the first movable member 21 rest on the inside of the lower edge of the second air outlet 112 (i.e., the first blocking portion 1a), thereby closing the second air outlet 112.

[0054] 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, and the first movable member 21 abuts against 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 valve 2 can only pass the airflow flowing from outside the shell 1 to the main air duct 11, and cannot pass the airflow flowing from the main air duct 11 to outside the shell 1. Moreover, the first one-way valve 2 of this structure has a simple structure and low manufacturing cost.

[0055] 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°.

[0056] 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.

[0057] In an illustrative embodiment, the second one-way valve 3 includes a second rotating shaft 32 and a second movable member 31. The second rotating shaft 32 is connected to the housing 1. Second mounting holes 1183 are provided on two opposing side walls of the housing 1. The two second mounting holes 1183 are coaxially arranged, and the ends of the second rotating shaft 32 are respectively inserted into the two second mounting holes 1183. The second rotating shaft 32 and the second mounting holes 1183 may be an interference fit, thereby securing the second rotating shaft 32 to the housing 1. The third air outlet 113 is oriented parallel to a horizontal plane. The second rotating shaft 32 is located at the top of the third air outlet 113. The second rotating shaft 32 extends along the upper edge of the third air outlet 113 and is arranged horizontally. The second movable member 31 is plate-shaped. The shape of the second movable member 31 is the same as that of the third air outlet 113, for example, both are rectangular. The top end of the second movable member 31 is rotatably connected to the second rotating shaft 32, and the second movable member 31 can rotate freely about the second rotating shaft 32. The width of the second movable member 31 is the same as that of the third air outlet 113. 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 rest on the outside of the lower edge of the third air outlet 113 (i.e., the second blocking portion 1b), thereby closing the third air outlet 113.

[0058] In this way, when the pressure at the 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 the 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 the end of the main air duct 11 near the third air outlet 113 is negative, the second movable member 31 tends to swing inward from the main air duct 11. The second movable member 31 abuts against the outer side of the lower edge of the third air outlet 113, 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. Therefore, the second one-way valve 3 can only pass the airflow flowing from the main air duct 11 to the deodorization chamber 12, and cannot pass the airflow flowing from the deodorization chamber 12 to the main air duct 11. Moreover, the second one-way valve 3 of this structure has a simple structure and low manufacturing cost.

[0059] In an exemplary embodiment, when the bottom end of the second movable member 31 rests 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°.

[0060] 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.

[0061] In an exemplary embodiment, the deodorizing chamber 12 is disposed below one end of the main air duct 11 near the third air outlet 113. The deodorizing chamber 12 is configured as a rectangular cavity and is separated from the main air duct 11 by a wall.

[0062] The housing 1 is also provided with a drainage channel 115. The drainage channel 115 is arranged on the side of the third air outlet 113 facing away from the main air duct 11 and is located above the deodorizing chamber 12. The drainage channel 115 extends vertically. The side of the drainage channel 115 is connected to the third air outlet 113, and the bottom of the drainage channel 115 is connected to the top of the deodorizing chamber 12. The third air outlet 113 is connected to the top of the deodorizing chamber 12 through the drainage channel 115. The fourth air outlet 114 is arranged at the bottom of the deodorizing chamber 12.

[0063] 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 12 located below the drainage channel 115, thereby reducing the resistance to the airflow. At the same time, the airflow enters the deodorizing chamber 12 from the top and exits from the bottom of the deodorizing chamber 12. The air can evenly and fully contact the deodorizing medium 6 in the deodorizing chamber 12, and the deodorizing medium 6 has a better deodorizing effect.

[0064] In an illustrative embodiment, the housing 1 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 housing can be detachably connected. The rear cover 4 and the housing 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.

[0065] Thus, the back cover 4 covering the fourth air vent 114 prevents the deodorizing medium 6 from escaping from the deodorizing chamber 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.

[0066] 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.

[0067] 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 .

[0068] In the drying mode, the air flows from the fan module 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.

[0069] Example 2

[0070] like Figure 8 As shown, Figure 8 A drying device 100a in Example 2 is shown. The drying device 100a in Example 2 differs from the drying device 100 in Example 1 only in the fan module, while the other parts have the same structure. To avoid redundancy, only the differences between the two are described below.

[0071] The drying device 100a includes a fan module 2b. The fan module 2b of the drying device 100a includes a first fan 21b and a second fan 22b. 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 fan module 2b can be installed in the first installation space 119 through the installation opening 101. The first fan 21b and the second fan 22b are arranged sequentially along the main air duct 11. The first fan 21b supplies air to one end of the main air duct 11, and the second fan 22b supplies 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.

[0072] 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 valve 2 opens the main air duct 11 under the action of air pressure, and the second one-way valve closes the deodorization chamber 12 under the action of air pressure, and the airflow flows into the pot surface space to dry the buttocks.

[0073] 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 in the second direction of the configuration space, the second one-way valve opens the deodorization chamber 12 under the action of air pressure, and the first one-way valve 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.

[0074] Example 3

[0075] like Figure 11 As shown, the third embodiment proposes a drying device 100b. The difference between the drying device 100b of the third embodiment and the drying device 100 of the first embodiment lies in the one-way valve. The structures of other parts are the same. To avoid redundancy, the following mainly introduces the differences between the two.

[0076] Drying device 100b includes an air duct assembly 10b. Air duct assembly 10b includes a housing 1 and a first one-way valve 3a. The structure of housing 1 of air duct assembly 10b is identical to that of housing 1 in Example 1. First one-way valve 3a is mounted on lower housing 118 of housing 1. First one-way valve 3a can be installed through mounting opening 101 in lower housing 118 into one end of main air duct 11, which is enclosed by lower housing 118 and upper housing 117.

[0077] The first one-way valve 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 arranged relative to the lower shell 118. 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 constructed as flat plates. One end of the first movable portion 311a is connected to one end of the second movable portion 312a. An angle can be formed between the first movable portion 311a and the second movable portion 312a. The intersection of the first movable portion 311a and the second movable portion 312a is connected to the lower shell 118 of the housing 1 via the third rotating shaft 34a, so that the third movable member 31a is rotatably connected to the lower shell 118 of the housing 1. The third rotating shaft 34a is arranged between the second air outlet 112 and the third air outlet 113, and the two ends of the third rotating shaft 34a are respectively connected to the opposite side walls of the lower shell 118 of the housing 1. The first movable portion 311a is positioned upstream of the second air port 112, along the direction of air flow from the second air port 112 into the main air duct 11. The second movable portion 312a is positioned upstream of the third air port 113, along the direction of air flow from the third air port 113 into the main air duct 11. 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.

[0078] The first blocking portion 32a is disposed downstream of the first movable portion 311a along the direction of flow from the second air port 112 into the main air duct 11. The second blocking portion 33a is disposed upstream of the second movable portion 312a along the direction of flow from the first air port 111 into the main air duct 11. 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 port 112 and the bottom of the third air port 113, respectively.

[0079] The third movable part 31a is configured so that when the fan module 5 is not working and the fan module 5 is transporting air 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.

[0080] The third movable part 31a is configured so that when the fan module 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.

[0081] In this way, when the fan module 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, and the first movable portion 311a moves away from the second air port 112, opening the second air port 112. Air flows through the second air port 112 toward the first air port 111. The fan module 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, and the second movable portion 312a moves away from the third air port 113, opening the third air port 113. Air flows sequentially through the first air port 111 and the third air port 113 toward the fourth air port 114.

[0082] This drying device 100b only needs to be provided with one fan module 5, and does not need to be provided with an additional motor for changing the wind direction of the fan module 5, so the production cost is low. At the same time, this drying device 100b has a simple and compact structure and occupies less space.

[0083] 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 module 5 is not operating and the fan module 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.

[0084] In this way, when the fan module 5 is not working and the fan module 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 .

[0085] 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 .

[0086] In this way, the fan module 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 the first air outlet 111 to take in air and the fourth air outlet 114 to discharge air.

[0087] Example 4

[0088] like Figure 14 As shown, the fourth embodiment proposes a drying device 100d. The difference between the drying device 100d of the fourth embodiment and the drying device 100 of the first embodiment lies mainly in the different structure of the housing and the position of the fan module in the housing. To avoid redundancy, the following mainly introduces the differences between the two.

[0089] The drying device 100d includes an air duct assembly 10d, a fan module 5, a heating module 7, and a deodorizing medium 6. The air duct assembly 10d includes a housing 1c, a first one-way valve 9a, and a second one-way valve 9b.

[0090] The shell 1c is a thin shell structure. The shell 1c includes an upper shell 117c and a lower shell 118c. The lower shell 118c is located below the upper shell 117c. One of the lower shell 118c and the upper shell 117c is provided with a mounting opening 101c, and the other of the lower shell 118c and the upper shell 117c covers the mounting opening 101c. The mounting opening 101c is provided on the lower shell 118c. The lower shell 118c is connected to the upper shell 117c. The upper shell 117c and the lower shell 118c can be connected by a snap. The upper shell 117c and the lower shell 118c enclose the main air duct 10c, the first air outlet 111c and the second air outlet 112c. The main air duct 10c is constructed as a long strip of air duct. The main air duct 10c can be arranged horizontally. The first air port 111c is disposed at one end of the main air duct 10c, and the second air port 112c is disposed at the other end of the main air duct 10c. The installation opening 101c is connected to the main air duct 10c. The installation opening 101c may be disposed at the top of the main air duct 10c. The installation opening 101c is used to allow the fan module 5, heating module 7, deodorizing medium 6, first one-way valve 9a, and second one-way valve 9b to pass through, allowing the fan module 5, heating module 7, deodorizing medium 6, first one-way valve 9a, and second one-way valve 9b to be installed in the main air duct 10c.

[0091] Before the upper shell 117c and the lower shell 118c are assembled together, the fan module 5, the heating module 7, the deodorizing medium 6, the first one-way valve 9a, and the second one-way valve 9b can be installed on the lower shell 118c first, and then the upper shell 117c and the lower shell 118c are assembled together, which makes it easier to install the fan module 5, the heating module 7, the deodorizing medium 6, the first one-way valve 9a, and the second one-way valve 9b on the shell 1.

[0092] The first air vent 111c is connected to the toilet pot surface space, and the second air vent 112c is connected to the toilet configuration space. The main air duct 10c is connected to the pot surface space 301 of the seat body through the first air vent 111c, and is connected to the configuration space 302 of the seat body through the second air vent 112c.

[0093] A partition 11c and a branch channel 12c are provided on the lower shell 118c. The partition 11c and the branch channel 12c are both provided in the main air duct 10c. The partition 11c is located between the first air outlet 111c and the second 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 third air outlet 113c and a fourth air outlet 114c are provided on the partition 11c. The third air outlet 113c and the fourth air outlet 114c both pass through the partition 11c, and the relative positions of the third air outlet 113c and the fourth air outlet 114c are not limited. The third air outlet 113c can be provided above the fourth 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 second air outlet 112c. One end of the branch channel 12c is connected to the fourth air outlet 114c. The fan module is arranged between the partition 11c and the second air port 112c. The branch channel 12c extends from the fourth air port 114c to the fan module 5, and the end of the branch channel 12c facing away from the fourth air port 114c faces the fan module 5. The heating module 7 is arranged between the partition 11c and the first air port 111c.

[0094] The drying device 100d further includes a deodorizing medium 6. The deodorizing medium 6 is disposed in the branch flow channel 12c.

[0095] The first one-way valve 9a is arranged at the third air port 113c. The first one-way valve 9a includes a first movable part 91a and a first blocking portion 93a. The first blocking portion 93a is arranged upstream of the first movable part 91a along the direction of fluid flowing from the third air port 113c to the first air port 111c. The first blocking portion 93a can be a protrusion arranged at the lower edge of the third air port 113c. The first movable part 91a is movably arranged relative to the lower shell 118c of the shell 1c, and the first movable part 91a can, for example, be rotatable or slidable relative to the lower shell 118c of the shell 1c. In this embodiment, the first one-way valve 9a also includes a first rotating shaft, and the two ends of the first rotating shaft 92a are connected to the opposite side walls of the lower shell 118c of the shell 1c, and are located above the third air port 113c. The first movable member 91a is configured as a flat plate-like structure parallel to the first rotating shaft 92a. The top end of the first movable member 91a is connected to the first rotating shaft 92a. The first movable member 91a is rotatably connected to the lower shell 118c of the housing 1c via the first rotating shaft 92a. When the fan module 5 delivers air toward the second air outlet, the first movable member 91a is subjected to pressure from the fluid flowing into the configuration space and engages the first blocking portion 93a, thereby closing the third air outlet 113c. When the fan module 5 delivers air toward the first air outlet 111c, the first movable member 91a is subjected to pressure from the fluid flowing into the pot surface space and opens the third air outlet 113c, allowing air to flow through the second and third air outlets 112c, 113c, and toward the first air outlet 111c.

[0096] The second one-way valve 9b is arranged at the fourth air port 114c. The second one-way valve 9b includes a second movable member 91b and a second blocking portion 93b. The second blocking portion 93b is arranged upstream of the second movable member 91b along the direction of fluid flowing from the fourth air port 114c to the second air port 112c. The second blocking portion 93b can be a protrusion arranged at the lower edge of the fourth air port 114c. The second movable member 91b is movably arranged relative to the lower shell 118c of the shell 1c, and the second movable member 91b can, for example, be rotatable or slidable relative to the lower shell 118c of the shell 1c. In this embodiment, the second one-way valve 9b also includes a second rotating shaft 92b, and both ends of the second rotating shaft 92b are connected to the opposite side walls of the lower shell 118c of the shell 1c, and are located above the fourth air port 114c. The second movable member 91b is configured as a flat plate structure parallel to the second rotating shaft 92b. The top end of the second movable member 91b is connected to the second rotating shaft 92b. The second movable member 91b is rotatably connected to the lower shell 118c of the housing 1c via the second rotating shaft 92b. The second movable member 91b is configured such that when the fan module 5 supplies air to the first air port 111c, the pressure of the fluid flowing into the pot surface space causes the second movable member 91b to engage the second blocking portion 93b to close the fourth air port 114c. When the fan module 5 supplies air to the second air port, the pressure of the fluid flowing into the configuration space causes the second movable member 91b to open the fourth air port 114c, allowing air to flow through the first air port 111c, the fourth air port 114c, and the deodorizing medium 6 to the second air port 112c.

[0097] like Figure 15 As shown, in drying mode, heating module 7 heats air, while fan module 5 delivers air to first air port 111c. Driven by air pressure, first one-way valve 9a opens third air port 113c, while second one-way valve 9b closes fourth air port 114c. Air then flows sequentially through second air port 112c, fan module 5, third air port 113c, and heating module 7 before exiting first air port 111c. The air exiting first air port 111c can dry the buttocks. Furthermore, since second one-way valve 9b closes fourth air port 114c, it prevents the deodorizing medium 6 in branch channel 12c from contaminating the drying air exiting first air port 111c.

[0098] like Figure 16 As shown, in the deodorization working mode, the heating module 7 does not heat the air, and the fan module 5 delivers airflow to the second air port 112c. Driven by the air pressure, the first one-way valve 9a closes the third air port 113c, and the second one-way valve 9b opens the fourth air port 114c. The airflow flows through the first air port 111c, the fourth air port 114c, the branch channel 12c, and the fan module 5 in sequence, and is finally output from the second air port 112c. When the air flows through the branch channel 12c, the deodorization medium 6 absorbs odor molecules in the air, and the air after deodorization is discharged from the second air port 112c.

[0099] like Figure 16 As shown, in the dehumidification working mode, the heating module 7 heats the air, and the fan module 5 delivers air flow to the second air outlet 112c. Driven by the air pressure, the first one-way valve 9a closes the third air outlet 113c, and the second one-way valve 9b opens the fourth air outlet 114c. The air flows through the first air outlet 111c, the heating module 7, the fourth air outlet 114c, the branch channel 12c, and the fan module 5 in sequence, and is finally output from the second 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 second air outlet 112c can dehumidify the electrical components on the functional components 200 in the configuration space 302.
