[0020] The embodiments of the utility model will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

[0021] As shown in the accompanying Figure 1 to the accompanying Figure 4 As shown:

[0022] Example one: the utility model provides a kind of based on toilet ventilating system of health, including toilet body 1, and be equipped with air inlet 2 in toilet body 1 and be located below toilet ring, the back of toilet body 1 bottom is equipped with containing cavity 3, the innermost part of containing cavity 3 is equipped with air outlet 4 with air inlet 2 intercommunication, containing cavity 3 is equipped with micro centrifugal fan 5 of external power supply, the air outlet of micro centrifugal fan 5 is equipped with gas pipeline 6, the other end of gas pipeline 6 is connected with ventilation pipe 7;

[0023] It further includes detection component, and detection component is vertically installed on gas pipeline 6 and with each other intercommunication.

[0024] It needs to be explained that, by being equipped with air inlet 2 and air outlet 4 on toilet body 1, air outlet 4 is installed in containing chamber and with air inlet 2 intercommunication, micro centrifugal fan 5 is arranged in containing chamber, when person defecates, by starting micro centrifugal fan 5 to exhaust containing chamber, to form negative pressure, the peculiar smell in toilet is transported to air outlet 4 in air inlet 2, and finally is transported to ventilation pipe 7 in gas pipeline 6, to realize the absorption of peculiar smell in toilet body 1, effectively avoid the situation that excrement peculiar smell spreads in bathroom.

[0025] In the embodiment, containing cavity 3 is equipped with support block 8, micro centrifugal fan 5 is installed on support block 8, and the side of support block 8 close to gas pipeline 6 is equipped with control module 9 of external power supply.

[0026] It needs to be explained that, by being equipped with control module 9, control module 9 can control the power of micro centrifugal fan 5, so that when user sits down, micro centrifugal fan 5 runs at low speed, after use, micro centrifugal fan 5 runs at high speed, and the flexibility of discharging peculiar smell is improved.

[0027] In the embodiment, infrared sensor 10 is arranged on the cover plate of toilet body 1, and infrared sensor 10 is directed to the side of human body when the cover plate on toilet body 1 is vertically placed, and infrared sensor 10 and micro centrifugal fan 5 are electrically connected with control module 9, and the external power supply of micro centrifugal fan 5 is 220V alternating current.

[0028] It should be noted that the infrared sensor 10 is composed of an infrared emitting tube and an infrared receiving tube (phototransistor or photodiode). The emitting end continuously emits infrared light of a specific wavelength (such as 940nm); the receiving end detects the intensity of the reflected infrared light and converts it through photoelectric conversion.

[0029] When a user sits down, the human body reflects some infrared light, which amplifies the signal at the receiver. The infrared receiver converts the light signal into an electrical signal, which is then processed by an amplifier and filter circuit before being transmitted to the control module 9 to read the voltage value. Finally, the signal is transmitted to the micro centrifugal fan 5 to control its start.

[0030] To further improve accuracy, a pressure sensor connected to the controller can be installed at the bottom of the toilet seat. The pressure sensor operates as follows: the user sits down → the infrared sensor detects the enhanced reflected signal and the pressure sensor detects pressure >5kg → the fan starts in low-speed mode (40% power) → the pressure returns to zero after the user gets up → the fan switches to high-speed mode (100% power) and runs for 30 seconds → then turns off.

[0031] In this embodiment, the detection component includes a branch pipe 11 and a gas detector 12. The probe of the gas detector 12 extends into the branch pipe 11. The branch pipe 11 is vertically installed on the gas transmission pipe 6 and is interconnected with it. The gas detector 12 has a built-in wireless connection module.

[0032] It should be noted that, through the set detection components, the gas detector 12 is installed on the branch pipe 11. When a person urinates, most of the odor will enter the ventilation pipe 7 through the gas supply pipe 6, but a small part of the odor will enter the branch pipe 11. The gas detector 12 is electrically connected to the control module 9. When the micro centrifugal fan 5 is started, the gas detector 12 will also be started, thereby detecting other components in the odor. The gas detector 12 uses a nanomaterial electrochemical sensor and is connected to the data analysis unit of the control module 9 (with a built-in gas concentration-health index conversion algorithm). Through gas component analysis, it reflects the health status of the user's digestive system. The analyzed data is sent to the person's mobile phone via Bluetooth / WiFi, so that the person can judge whether there is a risk of gastrointestinal diseases.

[0033] In this embodiment, the top of the branch pipe 11 is provided with a movable mounting frame 13. The cross-section of the mounting frame 13 is "U" shaped and is vertically inserted into the branch pipe 11. The inside of the branch pipe 11 is provided with a fixedly connected grid plate 14. On the top of the grid plate 14, there are multiple layers of activated carbon 15.

[0034] It should be noted that by arranging the grid plate 14 inside the mounting frame 13, the activated carbon layer 15 is placed on the grid plate 14, when the gas flows upward after being detected in the branch pipe 11, the activated carbon layer 15 can be adsorbed to the odor, so that the gas from the mounting frame 13 can avoid the odor.

[0035] In the embodiment, the bottom of the mounting frame 13 is provided with a sealing ring 16, and the inner wall of the sealing ring 16 is movably attached to the outer wall of the branch pipe 11.

[0036] It should be noted that the mounting frame 13 and the branch pipe 11 are movably inserted, so that the activated carbon layer 15 can be conveniently replaced, and the convenience is improved, and the sealing ring 16 is arranged at the bottom of the mounting frame 13, and the inner wall of the sealing ring 16 is movably attached to the outer wall of the branch pipe 11, so that the sealing property between the mounting frame 13 and the branch pipe 11 after being inserted into the branch pipe 11 can be improved, and the odor from the gap between the two can be avoided.

[0037] The use method of the above embodiment is that when a person sits on the toilet body 1 to defecate, the infrared sensor 10 detects that the person is defecating, and transmits a signal to the control module 9, the control module 9 drives the micro centrifugal fan 5 to start, and the containing chamber is sucked to form a negative pressure, so that the odor in the toilet body 1 enters the air inlet 2, and then enters the micro centrifugal fan 5 from the air outlet 4, and then is transported to the conveying pipe from the air outlet of the micro centrifugal fan 5, and finally enters the ventilation pipe 7;

[0038] A part of the odor flows in the gas conveying pipe 6 and enters the branch pipe 11, the branch pipe 11 is provided with a gas detector 12, which detects the gas component in the odor, and the health status of the user is understood in real time, and the concept of "defecating and checking" is highlighted, and after the result is analyzed, the result is sent to the mobile phone of the user, and the odor in the branch pipe 11 is adsorbed by the activated carbon layer 15 in the mounting frame 13 when flowing upward, so that the odor of the gas from the branch pipe 11 is avoided.

[0039] When the person finishes defecating, the infrared sensor 10 detects that the user gets off, and the control module 9 closes the micro centrifugal fan 5 and the gas detector 12, so that the odor is removed, and the odor during defecation is avoided.
