[0025] The present invention is further described below through specific implementation methods.

[0026] Reference Figures 1 to 7 As shown, an exhaust gas deodorization device based on cold catalyst includes a shell 1, an induced draft fan 2, a deodorization box 3, a controller, and a base 5.

[0027] The housing 1 has an airflow chamber 11, one end of the airflow chamber 11 is provided with an air suction port 12, and the other end is provided with an air outlet 13. The induced draft fan 2 is arranged in the housing 1, and the induced draft fan 2 provides a driving force for the airflow to be sucked in from the air suction port 12 and discharged from the air outlet 13. In a specific embodiment, the induced draft fan 2 is a turbo fan; the controller is connected to and controls the working state of the turbo fan.

[0028] The deodorizing box 3 is installed at the air outlet 13 of the shell 1. A cold catalyst purification block 4 is provided in the deodorizing box 3. A plurality of purification channels which are arranged through and densely arranged are formed in the cold catalyst purification block 4. In one embodiment, the cold catalyst purification block includes a plurality of straight plates 42 and a plurality of tooth wave plates 43. The tooth wave plates 43 have a tooth-shaped cross-section extension structure. The straight plates 42 and the tooth wave plates 43 are alternately stacked and connected to form the plurality of purification channels between the straight plates 42 and the tooth wave plates 43. The wall of the purification channel is covered with a platinum catalyst layer. The airflow in the shell 1 passes through at least one purification channel and is discharged.

[0029] The shell is installed on the base 5, and the deodorizing box 3 includes a box body 31. The top surface of the box body 31 is open, and a plurality of ventilation holes 32 are provided on the bottom surface. The side wall of the box body 31 is provided with a first buckle 33, and a mounting position 51 is provided at the bottom of the base 5. The inner wall of the mounting position 51 is provided with a second buckle 52. The box body 31 is arranged in the mounting position 51, and the first buckle 33 and the second buckle 52 are engaged with each other to form a detachable connection structure.

[0030] The working principle of this cold catalyst-based exhaust deodorization device is as follows: when the induced draft fan 2 is working, the odor is sucked into the airflow chamber 11 from the air inlet 12 and injected into the deodorization box 3. The odor is dispersed from the air outlet 13 and passes through various purification channels before being discharged. The odor is decomposed under the catalytic action of the platinum catalyst layer to achieve a deodorization effect. The controller can adjust the on / off state and working power of the induced draft fan 2 in real time. By adjusting the appropriate working power of the induced draft fan 2, noise control and deodorization efficiency are balanced to achieve a better smart toilet user experience.

[0031] A smart toilet includes a human body cleaning component, which includes an exhaust and deodorizing device, a base 5, and a flushing component 6. The exhaust and deodorizing device and the flushing component 6 are installed on the same base 5, and the exhaust and deodorizing device and the flushing component 6 are arranged close to each other on the left and right sides.

[0032] The smart toilet adopts the following working modes to achieve dynamic control deodorization:

[0033] After the person sits down, the induced draft fan 2 in the exhaust and deodorization device starts to rotate, and the odor in the toilet bowl is sucked in from the air inlet 12. The odor reaches the purification channel in the cold catalyst purification block 4, and the platinum catalyst on the surface of the purification channel catalytically reacts to remove the odor, and the gas and the remaining odor that has not had time to be catalyzed are discharged.

[0034] Specific description of the dynamic deodorization startup process status:

[0035] 1) In the early stage of seating, the induced draft fan 2 runs at a low duty cycle speed. During this process, the amount of odor is relatively small, so the induced draft fan 2 runs at a low speed to absorb the odor;

[0036] 2) In the middle of the seat, the induced draft fan 2 runs at a high duty cycle speed. Since the amount of odor generated by defecation is large at this time, the induced draft fan 2 runs at a high speed and absorbs the odor;

[0037] 3) Entering the tail section, the induced draft fan 2 runs at a low duty cycle speed. In this process, since the amount of odor at the tail end is relatively small, the induced draft fan 2 runs at a low speed to absorb the odor.

[0038] The above induced draft fans control the speeds at different duty cycles to achieve a good deodorizing effect and ensure comfort in use.

[0039] After the human body has finished defecating, the flushing component 6 starts to start, and performs functions such as buttocks washing / female washing / strong washing, and the deodorizing fan operates as follows:

[0040] 1) After the flushing function is started, the water column sprayed by the flushing contacts the human body and spreads in all directions. Part of the water column will be absorbed into the deodorizing body by the negative pressure generated by the induced draft fan 2. There are electronic devices in the deodorizing body. Therefore, during this operation, the induced draft fan 2 needs to reduce the duty cycle (run at a low speed) to prevent a large amount of water vapor from entering the deodorizing body;

[0041] 2) After the flushing is completed, the induced draft fan 2 is operated at a low duty cycle speed for a period of time, which is also to prevent the water vapor on the toilet bowl surface from entering the deodorizing body.

[0042] The above is only a specific implementation of the present utility model, but the design concept of the present utility model is not limited to this. Any non-substantial changes to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
