With continuing reference to fig. 1 and 2, the toilet bowl 10 of the present invention has the following working principle:

1. the gas detection device 130 acquires the concentration of odor in the area where the odor includes ammonia gas and hydrogen sulfide.

In this embodiment, the odor includes ammonia gas and hydrogen sulfide, wherein the ammonia gas in the odor is mainly from urine, while the excrement and the exhaust gas discharged from the anus mainly contain hydrogen sulfide, and the ammonia gas and the hydrogen sulfide in high concentration are harmful to human body and need to be treated.

In the present embodiment, the odor can be detected by the gas detection device 130 by diffusion. In other embodiments, the odor may be sent to the gas detection device 130 by some air extraction device 150 such as a fan to increase the detection speed of the odor concentration.

2. The processing unit 140 acquires the odor concentration, and the processing unit 140 determines whether the odor concentration is greater than or equal to a preset threshold value;

wherein obtaining the odor concentration can be placing the treatment unit 140 in the odor or, alternatively, using a device such as an exhaust fan to carry the odor to the processor unit.

In this embodiment, the processing unit 140 may obtain the ammonia gas concentration and the hydrogen sulfide concentration respectively, and when at least one of the ammonia gas concentration and the hydrogen sulfide concentration is greater than or equal to a preset threshold, the processing unit 140 determines that the odor gas concentration is greater than or equal to the preset threshold.

As an example, the threshold concentrations of ammonia gas and hydrogen sulfide gas determined by experiments to be 0.1ppm (parts per million concentration) and 0.0005ppm, respectively, in the area where the human body does not feel noticeable, may be stored by the gas detection device 130 as the preset threshold values. When the human body performs defecation, the processing unit 140 determines that the odor concentration is greater than or equal to the preset threshold when the gas detection device 130 detects that the ammonia concentration is greater than or equal to 0.1ppm or the hydrogen sulfide concentration is greater than or equal to 0.0005ppm or the ammonia concentration is greater than or equal to 0.1ppm and the hydrogen sulfide concentration is greater than or equal to 0.0005 ppm.

In other embodiments, the odor concentration may be the total concentration of ammonia gas and hydrogen sulfide, that is, the processing unit 140 determines that the odor concentration is greater than or equal to the preset threshold value only when the total concentration of ammonia gas and hydrogen sulfide is greater than or equal to the preset threshold value.

As an example, the preset threshold concentration is 0.1ppm +0.005 ppm-0.1005 ppm, and the processing unit 140 determines that the concentration of the malodor is greater than or equal to the preset threshold value when the total concentration of the malodor is greater than or equal to 0.1005 mmp.

The processing unit 140 may determine whether the concentration of the odor is greater than or equal to a preset threshold by comparing the concentration of the odor with the preset threshold.

3. When the odor concentration is greater than or equal to the preset threshold, the processing unit 140 sends a control instruction for instructing the air extractor 150 to extract air according to the preset air pressure.

In one embodiment, when the ammonia gas concentration is greater than or equal to the preset threshold, the processing unit 140 sends a control instruction for instructing the air exhaust device 150 to exhaust air at a predetermined air pressure.

In one embodiment, when the concentration of hydrogen sulfide is greater than or equal to the preset threshold, the processing unit 140 sends a control instruction for instructing the air exhaust device 150 to exhaust air with a predetermined air pressure.

In one embodiment, when the total concentration of ammonia and hydrogen sulfide is greater than or equal to the preset threshold, the processing unit 140 sends a control instruction for instructing the air exhaust device 150 to exhaust air at a predetermined air pressure.

In one embodiment, when the ammonia gas concentration is greater than or equal to the preset threshold and the hydrogen sulfide concentration is also greater than or equal to the preset threshold, the processing unit 140 sends a control instruction for instructing the air exhaust device 150 to exhaust air at a predetermined air pressure.

In some embodiments, when the odor concentration is greater than or equal to the preset threshold, the processing unit 140 determines the suction negative pressure according to the current odor concentration, and sends a control instruction according to the suction negative pressure for instructing the suction device 150 to open suction at a predetermined suction negative pressure. As an example, when the gas detection device 130 detects that the ammonia gas concentration is 0.5ppm or the hydrogen sulfide concentration is 0.001ppm, the processing unit 140 determines that the extraction negative pressure is-100 pa, and the processor instructs the extraction device 150 to start extraction at an extraction negative pressure of-100 pa. As another example, when the gas detection device 130 detects an ammonia gas concentration of 1ppm or a hydrogen sulfide concentration of 0.002ppm, the processing unit 140 determines that the pumping negative pressure is-200 pa, and the processor instructs the pumping device 150 to start pumping at a pumping negative pressure of-200 pa.

In some embodiments, the processing unit 140 prestores a mapping table, where the mapping table includes a mapping relationship between the odor concentration value and the suction negative pressure. The processing unit 140 queries the mapping table according to the current odor concentration, obtains the corresponding pumping negative pressure, and sends a control instruction according to the obtained pumping negative pressure. The mapping relationship table can record the mapping relationship between the concentration value of the odor and the pumping negative pressure, that is, the concentration value of one hydrogen sulfide corresponds to one pumping negative pressure, and the concentration value of one ammonia gas also corresponds to one pumping negative pressure, and the processing unit 140 can obtain the corresponding pumping negative pressure according to the current odor concentration, and send a control instruction according to the obtained odor negative pressure to control the rotation speed of the pumping device 150. The processing unit 140 can accurately obtain the negative pressure of air exhaust according to the current odor concentration by pre-storing the mapping relationship table, so that the air exhaust efficiency of the air exhaust device 150 is improved.

As an example, when the odor concentration in the toilet bowl is greater than the threshold value and continuously increases or proportionally increases, the processor may adjust the pumping negative pressure according to the current actual odor concentration, and the PID regulator may re-modulate the pulse signal having the pulse width corresponding to the adjusted pumping negative pressure according to the adjusted pumping negative pressure and send the pulse signal to the air extractor 150 as a control instruction to increase the rotation speed of the air extractor 150, thereby achieving fast and effective deodorization.

As another example, when the odor concentration gradually decreases to approach the threshold value, for example, the ammonia concentration is 0.101ppm or the hydrogen sulfide concentration is 0.00051ppm, the processor may adjust the extraction negative pressure according to the current actual odor concentration, and the PID controller may re-modulate the pulse signal having the pulse width corresponding to the adjusted extraction negative pressure according to the adjusted extraction negative pressure and send the pulse signal as a control instruction to the air extractor 150 to decrease the rotation speed of the air extractor 150. Because the toilet bowl can automatically adjust the rotating speed of the air exhaust device 150 according to the odor concentration without long-time full-power work, the energy consumption of the toilet bowl is reduced to a certain extent, and the energy conservation is realized.

The PID regulator can remodulate a pulse signal having a pulse width corresponding to the adjusted pumping negative pressure according to the adjusted pumping negative pressure, and send the pulse signal to the pumping device 150 as a control instruction, thereby realizing control of the rotational speed of the pumping device 150. Namely, the toilet bowl 10 can automatically adjust the air extractor 150 by frequency conversion according to the odor concentration, thereby effectively removing the odor, realizing energy saving and reducing the energy consumption of the toilet bowl 10.

In one embodiment, when the odor concentration is less than the preset threshold, a stop control instruction is sent, and the stop control instruction is used for instructing the air exhaust device 150 to stop the air exhaust.

In this embodiment, when the ammonia gas concentration is less than the first preset threshold and the hydrogen sulfide concentration is less than the second preset threshold, the processor sends a stop control command to instruct the air exhaust device 150 to stop exhausting air. The air extractor 150 can also stop working when the ammonia gas concentration is less than the first preset threshold and the hydrogen sulfide concentration is less than the second preset threshold, so that continuous working is not needed, the energy consumption of the toilet is reduced to a certain extent, and energy conservation is realized.

To sum up, the utility model provides a toilet bowl 10 acquires the foul smell concentration in the place region through gas detection device 130, and whether processing unit 140 confirms foul smell concentration and is greater than or equal to the predetermined threshold value, and when foul smell concentration is greater than or equal to the predetermined threshold value, processing unit 140 sends control command for instruct air exhaust device 150 to bleed according to predetermined wind pressure, the foul smell that produces when can in time detach user's stool and urine keeps the air fresh.
