[0026] The present invention will be further described below through specific embodiments.

[0027] Reference Figures 1 to 6 As shown, a high-efficiency exhaust deodorization device includes an air inlet channel 1, a fan 2, an air outlet channel 3, and a catalyst module 4.

[0028] The air intake channel 1 has an air inlet 11 at its first end and is connected to the air intake 21 of the fan 2 at its last end. The air intake channel 1 has a structure in which the cross-section gradually expands from the first end to the last end, and the cross-section at the last end of the air intake channel 1 covers the area of ​​the air intake 21 of the fan 2. Specifically, the air intake channel 1 includes a bottom plate 12 and a top plate 13. The top plate 13 is arranged at an inclination relative to the bottom plate 12, and the bottom plate 12 and the top plate 13 form a structure in which the cross-section of the air intake channel 1 gradually expands from the first end to the last end.

[0029] The first end of the air outlet channel 3 is connected to the exhaust port 22 of the fan 2, and the last end is connected to the catalyst module 4. The air outlet channel 3 has a gradually expanding cross-section from the first end to the last end, and the last cross-section of the air outlet channel 3 covers the end area of ​​the catalyst module 4. The cross-sectional area of ​​the exhaust port 22 of the fan 2 is smaller than the cross-sectional area of ​​the intake port 21 of the fan 2, and the cross-sectional area of ​​the first end of the air outlet channel 3 is not smaller than the cross-sectional area of ​​the exhaust port of the fan 2. The distance between the first and last ends of the air outlet channel 3 is 13mm-19mm, preferably 16mm. At least one side wall of the air outlet channel 3 has an inclined side wall structure. The inner wall of the inclined side wall structure is inclined towards the catalyst module 4. When the airflow cannot directly flow back through the catalyst module, it can flow back towards the catalyst module again after impacting the inclined side wall structure. This duct structure reduces the airflow velocity while ensuring the efficiency of airflow.

[0030] The catalyst module 4 includes a housing 41 and a platinum catalyst 42. The housing 41 is detachably installed below the air outlet channel 3. The top of the housing 41 has a top opening. The platinum catalyst 42 is replaceably installed inside the housing 41. There is a gap between the top surface of the platinum catalyst 42 and the top opening of the housing 41. The bottom of the housing 41 has several air holes 411. The platinum catalyst 42 has densely arranged vertical through holes 421. One end of the vertical through holes 421 faces the air outlet channel 3, and the other end faces the air holes 411.

[0031] Fan 2 is an axial flow fan.

[0032] A toilet includes a toilet body and a toilet seat main unit, wherein a high-efficiency exhaust deodorization device is disposed inside the toilet seat main unit.

[0033] The working principle of this application will be further explained below.

[0034] The air intake channel 1 of this application has a gradually expanding cross-section from the first end to the last end. Therefore, the cross-section at the air inlet 11 is small, resulting in a high airflow velocity, which is beneficial for quickly drawing in external odors. After the odors enter the air intake channel 1, due to the gradually expanding cross-section, the air resistance is low, which is conducive to the rapid transport of odors. The end cross-section of the air intake channel 1 covers the area of ​​the suction port 21 of the fan 2, reducing the suction resistance of the suction port 21 of the fan 2 and effectively ensuring the utilization rate of the suction power generated by the fan 2. The air outlet channel 3 of this application has a gradually expanding cross-section from the first end to the last end. The odors are dispersed during the process of passing through the air outlet channel 3, and the odors can pass evenly through the platinum catalyst 42, improving the decomposition efficiency of the platinum catalyst 42. The catalyst module 4 adopts a detachable and replaceable structure, which is easy to maintain.

[0035] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be considered as an infringement of the protection scope of the present utility model.
