[0024] The present invention will be further described below through specific embodiments.

[0025] Reference Figures 1 to 5 As shown, a low-resistance deodorization device includes a duct body 11, a deodorization fan 2, and a deodorization module 3.

[0026] The duct body 11 is mounted on the base 12. One end of the duct body 11 is an air intake 13, and the other end is an air outlet 14. The air outlet 14 is equipped with a deodorizing fan 2, which is an axial flow fan. The deodorizing fan 2 provides suction from the air intake 13 to the air outlet 14. The duct body 11 includes an air inlet section a, a first diffusion section b, and a second diffusion section c connected in sequence. The first diffusion section b expands in cross-section from the air inlet section a to the second diffusion section c. The second diffusion section c expands in cross-section from the first diffusion section b to the deodorizing fan 2. The cross-sectional area of ​​the end of the second diffusion section c covers the air intake range of the deodorizing fan 2.

[0027] Specifically, the two sides of the air duct body 11 are a straight side 15 and a multi-fold side 16, respectively. The multi-fold side 16 includes a first straight section 16a, a second straight section 16b, and a third straight section 16c. The first straight section 16a is arranged parallel to the straight side 15, and an air inlet section a is formed between the first straight section 16a and the straight side 15. The second straight section 16b is inclined relative to the straight side 15, and a first diffuser section b is formed between the second straight section 16b and the straight side 15. The third straight section 16c is inclined relative to the straight side 15, and a second diffuser section c is formed between the third straight section 16c and the straight side 15. The angle between the second straight section 16b and the flat side 15 is X, and the value of X ranges from 10° to 25°; the angle between the third straight section 16c and the flat side 15 is Y, and the value of Y ranges from 45° to 65°; there is a circular arc transition structure between the first straight section 16a and the second straight section 16b, and there is a circular arc transition structure between the second straight section 16b and the third straight section 16c.

[0028] The deodorization module 3 is installed on the base 12 and located outside the air outlet 14, with the exhaust direction of the deodorization fan 2 facing the deodorization module 3. The deodorization module 3 contains a deodorization medium, which includes one or more of platinum catalyst, activated carbon, and photocatalytic devices.

[0029] A toilet includes the aforementioned low-resistance deodorizing device.

[0030] The working principle of this application will be further explained below.

[0031] The low-resistance deodorization device of this application adopts a design where the cross-section from the air inlet 13 to the air outlet 14 gradually widens. The cross-section at the air inlet 13 is small, resulting in a fast airflow, which is conducive to the rapid intake of external odors. Subsequently, the odors enter the first diffusion section b and the second diffusion section c. The first diffusion section b and the second diffusion section c form a structure with gradually expanding cross-sections, which reduces the air resistance as the odors pass through, thus facilitating the rapid transport of odors. The cross-sectional area at the end of the second diffusion section c covers the air intake range of the deodorizing fan 2, reducing the intake resistance at the inlet of the deodorizing fan 2 and ensuring the utilization efficiency of the suction force generated by the deodorizing fan 2.

[0032] The two sides of the air duct body 11 of this application are a flat side 15 and a multi-fold side 16, and the multi-fold side 16 is composed of a first straight section 16a, a second straight section 16b, and a third straight section 16c. The cross-section enlargement structure is formed by combining multiple straight sections 16c. The straight section structure with an inclined angle is convenient for the design of the flare angle adjustment, and it is more convenient to carry out structural fine-tuning design for products of different sizes and models.

[0033] 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.
