[0037] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. DETAILED DESCRIPTION

[0038] The present invention is further described below through specific implementation modes.

[0039] See also Figures 1 to 7A deodorizing device includes a housing 10, a fan 20 and a deodorizing assembly 30. The housing 10 is a hollow structure, in which an air duct 11 is arranged, and the air duct 11 has an air inlet 12 and an air outlet 13. The fan 20 is located in the air duct 11 and at one end in the length direction of the housing 10. It inhales air through the air inlet 12 and then discharges the gas from the air outlet 13 to complete the air flow. The air duct 11 is divided into an air inlet duct 11a and an air outlet duct 11b. The air inlet duct 11a is connected to the air suction end of the fan 20 and extends along the length direction of the housing 10. The air inlet 12 is arranged at the other end of the air inlet duct 11a in the length direction of the housing 10. The air outlet duct 11b is connected to the air outlet side of the fan 20 and extends along the height direction of the housing 10. The air outlet 13 is close to one end in the height direction of the housing 10. The air inlet duct 11a and the air outlet duct 11b are also arranged adjacent to each other in the width direction of the housing.

[0040] The deodorizing assembly 30 is detachably mounted at the air outlet 13 of the air duct 11, and is located at the end of the air outlet duct 11b in the height direction, that is, at the end of the housing 10 in the height direction, and is used to deodorize the gas discharged from the air outlet 13. The deodorizing assembly 30 is designed to be detachably mounted at the air outlet 13 of the air duct 11, and this design makes the installation and maintenance of the deodorizing assembly 30 more convenient, ensuring that it maintains efficient deodorizing performance for a long time.

[0041] The deodorizing assembly 30 includes a deodorizing medium 31 and a box body 32. The deodorizing medium 31 is placed in the box body 32. An opening is provided on one side of the box body 32 relative to the air outlet 13 for the deodorizing medium 31 to be placed therein. The other side of the box body 32 is provided with a grid structure for the convenience of gas discharge. The box body 32 is detachably connected to the air inlet 12, such as threaded fit or snap fit. The deodorizing medium 31 is activated carbon, photocatalyst, diatom mud or biological deodorant, etc., which can be selected according to actual conditions. In this embodiment, a photocatalyst is used as an example, specifically a platinum catalyst. When the gas passes through the air duct 11 and is discharged from the air outlet 13, the platinum catalyst of the deodorizing assembly 30 decomposes the odor molecules (such as hydrogen sulfide, ammonia, methyl mercaptan, etc.) in the air into harmless substances through the catalytic action of platinum, thereby achieving the deodorizing effect. The platinum catalyst can also inhibit the growth of bacteria and viruses and reduce the odor caused by the growth of microorganisms.

[0042] This embodiment also achieves a highly compact design of the device by optimizing the structure of the housing 10: along the length direction of the housing 10, the air outlet 13 is arranged between the fan 20 and the air inlet 12, and the air outlet 13 and the air inlet 12 are also close to the two ends of the housing 10 in the height direction. In the width direction of the housing 10, the air inlet duct 11a and the air outlet duct 11b are separated by only one side wall. This three-dimensional layout effectively integrates the horizontal and vertical spaces, so that the fan 20, the air duct 11 and the air inlet and outlet 13 form a three-dimensional staggered structure, which reduces the horizontal extension space compared with the traditional housing 10 layout and significantly compresses the overall volume of the housing 10. The air inlet 12 and the air outlet 13 are also adjusted, and the partial or full direction of the air inlet 12 is set to be the same as the direction of the air outlet 13. The same-side opening design is adopted to avoid structural redundancy caused by multi-directional openings and optimize the outer dimensions of the housing 10.

[0043] The air inlet duct 11a is divided into a first section 14 and a second section 15. An air inlet 12 is provided at one end of the first section 14. The other end of the first section 14 is connected to one end of the second section 15. The other end of the second section 15 is connected to the air suction port of the fan 20. The volume of the second section 15 is greater than that of the first section 14. The air inlet 12 and the first section 14 are used to quickly absorb the odor. When the odor reaches the second section 15 with a larger volume, the flow rate of the odor is reduced, which facilitates the fan 20 to absorb the odor more efficiently. The air inlet duct 11a is also provided with a blocking surface 14a. The blocking surface 14a is located between the first section 14 and the second section 15. The blocking surface 14a is a corresponding side wall extending from the side wall of the first section 14 along the width direction of the housing 10 to one end of the second section 15. The blocking portion with an extension direction almost perpendicular to the flow direction of the odor can reduce the kinetic energy of the odor entering the second section 15 and further slow down its flow rate.

[0044] In practical applications, the first section 14 and the second section 15 extend along the length direction of the housing 10, and the cross-sections of the two sections may be different. The length and width of the first section 14 and the length and width of the second section 15 may be set according to actual conditions. The air outlet 11b and the air inlet 11a have an angle, for example, the two are arranged perpendicular to each other, and the size of the air outlet 13 can be adapted to the size of the deodorizing component 30, so that the odor is evenly dispersed to the surface of the deodorizing medium 31, such as the surface of the platinum catalyst, to improve the decomposition efficiency of the platinum catalyst.

[0045] Furthermore, the present invention also configures the air inlet 12 to include at least one air inlet hole group, each of which is provided with a plurality of long holes 12a spaced apart along the length direction or width direction of the housing 10. Compared with a single large through hole, the multiple long holes 12a can reduce the local resistance at the air inlet 12, more effectively guide the airflow into the air duct 11, and avoid the rapid change of the airflow at the air inlet 12. In the figure, at least one group of air inlet holes is provided on one side of the end of the housing 10 where the air inlet 12 is located, and a group of air inlet holes can also be provided on both sides of the end where the air inlet 12 is located.

[0046] In this embodiment, the end of the housing 10 where the air inlet 12 is located is provided with an inclined surface 19, and the inclined surface 19 extends obliquely from a position of the air inlet duct 11a close to the air outlet duct 11b to a position away from the air outlet duct 11b. The inclined surface 19 reduces the volume of the end of the housing 10 where the air inlet 12 is located, which is conducive to the installation of the housing 10 on other components.

[0047] Furthermore, the air outlet direction of the fan 20 is parallel to the air inlet duct 11a, and a guide portion 16a is provided on the side of the air outlet duct 11b opposite to the fan 20 to change the wind direction. The guide portion 16 extends along the height direction of the shell 10 so that the airflow blown out from the fan 20 is directed toward the deodorization component 30.

[0048] The housing 10 of the present invention can be configured as Figure 1 and Figure 2 An integrally formed structure, or configured as Figure 5 and Figure 6 Split structure. For the split structure, the housing 10 includes a first shell 16, a second shell 17 and a base 18, etc. The base 18 is provided with an air inlet 12 and an air outlet 13, and a slope 19 is formed at the air inlet 12 of the base 18. The air outlet 13 can be provided with a grid, and the deodorizing component 30 is detachably and fixedly connected to the outer periphery of the air outlet 13 of the base 18. The first shell 16 and the second shell 17 are detachably and fixedly connected and form a receiving chamber 17a, and the receiving chamber 17a has an opening on the side opposite to the air inlet 12 and the air outlet 13. The first shell 16 and the second shell 17 can be snap-fitted, and the fan 20 can be located in the receiving chamber 17a. The first shell 16 and the second shell 17 are also detachably and fixedly connected to the base 18 so that the above-mentioned air duct 11 is formed between the receiving chamber 17a and the base 18, and the first shell 16 and the second shell 17 are also respectively locked with the base 18 by screws. The guide portion 16 is formed on the first shell 16 or on the base 18 .

[0049] Based on this, the present invention also proposes a deodorizing base 18, see Figures 8 to 11, including a seat body 40 and the above-mentioned deodorizing device, the housing 10 is installed on the seat body 40, and the air inlet 12 and the air outlet 13 are located on the bottom surface of the base 18. The base 18 is the base 18 of the toilet, and other functional components, such as a cleaning component, a drying component, etc., can also be installed on the base 18. The housing 10 can be installed at a suitable position on the base 18, located on the left side, right side, or middle part of the base 18, etc., and is located on the left side of the base 18 in the figure, which does not affect the installation of relevant functional modules in the middle and right parts of the base 18.

[0050] The present invention also provides a deodorizing toilet, see Fig.12 and Fig.13 , comprising a barrel body 50 and the above-mentioned deodorizing base 18. The barrel body 50 is a ceramic barrel body, which is provided with a toilet bowl 51, and the base body 40 is installed in the installation cavity 52 at the rear side of the top of the barrel body 50. The shell 10 is located on the left or right side of the top of the toilet bowl 51, the air inlet 12 on the shell 10 faces the toilet bowl 51, the deodorizing component 30 is located outside the toilet bowl 51, and the air outlet 13 and the deodorizing component 30 are located in the installation cavity 52.

[0051] The deodorizing toilet of the present invention may also include other necessary parts of a toilet, such as a cover assembly, a flushing assembly, a flushing assembly, etc. When the deodorizing function of the toilet of the present invention is turned on, the fan 20 is controlled to start running, and the operation of the fan 20 causes a negative pressure to be generated in the air inlet duct 11a, absorbing the odor in the toilet bowl 51 of the toilet. The odor enters the air inlet duct 11a through the air inlet 12, is absorbed by the fan 20, and is transported to the air outlet duct 11b, and is evenly transported to the deodorizing assembly 30 through the air outlet 13 for deodorization and then discharged, for example, the odor is evenly dispersed on the surface of the platinum catalyst to improve the decomposition efficiency of the platinum catalyst.
