[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0031] like Figure 1 As shown, the present invention provides a fresh air delivery method based on smart toilet odor monitoring, comprising:

[0032] S101, obtaining the odor signal value around the smart toilet;

[0033] S102, determining whether the odor signal value is greater than a first preset signal value,

[0034] S103, when the judgment is yes, a driving voltage signal is generated according to the odor signal value and the driving voltage signal is sent to the ventilation mechanism to drive the ventilation mechanism to perform ventilation, wherein the operation rate of the ventilation mechanism decreases as the odor signal value decreases;

[0035] S104: When the judgment is no, the ventilation mechanism is not driven.

[0036] The present invention controls the operating rate of the ventilation mechanism according to the odor signal value around the smart toilet, wherein the operating rate of the ventilation mechanism decreases as the odor signal value decreases. The larger the odor signal value, the more odorous gases there are in the air, and the faster the operating rate of the ventilation mechanism is, so that the odorous gases are discharged at a faster speed; as the odorous gases are continuously discharged, the monitored odor signal value becomes smaller and smaller, which means that there are fewer odorous gases in the air, and the operating rate of the ventilation mechanism is smaller at this time, so that the operating noise of the ventilation mechanism is slowly and automatically reduced, and there is no need to manually adjust the ventilation mechanism, thereby improving the convenience of use of the ventilation mechanism.

[0037] Preferably, the operating rate of the ventilation mechanism satisfies: ν = S 气 *K, where ν is the operating speed of the ventilation mechanism, S 气 is the odor signal value, and K is the ventilation constant.

[0038] It should be noted that the operating rate of the ventilation mechanism is proportional to the odor signal value, and the ventilation constant is related to the structure of the ventilation mechanism. By adopting this embodiment, the ventilation mechanism can operate at a continuous rate, avoiding noise and system instability caused by excessive rate changes.

[0039] like Figure 2 As shown, further, the fresh air delivery method based on smart toilet odor monitoring also includes:

[0040] S201, determining whether the odor signal value is greater than a second preset signal value, and whether the second preset signal value is greater than the first preset signal value,

[0041] S202: When the judgment is yes, the operation rate of the ventilation mechanism satisfies: ν = S 气 *(S 气 / S2)*K, where ν is the operating speed of the ventilation mechanism, S 气 is the odor signal value, S2 is the second preset signal value, K is the ventilation constant,

[0042] S203: When the judgment is no, the operation rate of the ventilation mechanism satisfies: ν = S 气 *K, where ν is the operating speed of the ventilation mechanism, S气 is the odor signal value, and K is the ventilation constant.

[0043] It should be noted that the calculation formula for the operation rate of the ventilation mechanism is selected by judging whether the odor signal value is greater than the second preset signal value, that is, when the odor signal value is greater than the second preset signal value, the operation rate of the ventilation mechanism satisfies: ν = S 气 *(S 气 / S2)*K, where ν is the operating speed of the ventilation mechanism, S 气 is the odor signal value, S2 is the second preset signal value, and K is the ventilation constant; otherwise, the operating rate of the ventilation mechanism satisfies: ν=S 气 *K, where ν is the operating speed of the ventilation mechanism, S 气 is the odor signal value, and K is the ventilation constant. According to this embodiment, when the odor signal value is relatively large, the operation rate change rate of the ventilation mechanism is larger, and becomes smaller as the odor signal value becomes smaller, thereby exhausting the odorous air in the bathroom at a faster speed.

[0044] like Figure 3 As shown, preferably, the fresh air delivery method based on smart toilet odor monitoring also includes:

[0045] S301, determining whether the odor signal value is greater than a third preset signal value, wherein the third preset signal value is greater than the second preset signal value;

[0046] S302, when the judgment is yes, an audible and visual warning is issued to remind the user to stay away;

[0047] S303: If the judgment is no, it is not issued.

[0048] It should be noted that whether to remind the user to stay away is determined by judging whether the odor signal value is greater than the third preset signal value, that is, when the odor signal value is greater than the second preset signal value, an audible and visual warning is issued to remind the user to stay away; otherwise, no audible and visual warning is issued. With this embodiment, when the odor signal value is very large, it indicates that it is not suitable for the human body to stay for a long time, so it is necessary to issue an audible and visual warning to remind the user to stay away to avoid safety hazards.

[0049] like Figure 4 As shown, preferably, the fresh air delivery method based on smart toilet odor monitoring also includes:

[0050] S401, while obtaining the odor signal value around the smart toilet, obtaining the environmental monitoring temperature value of the temperature monitoring mechanism;

[0051] S402, controlling the switch of the heating mechanism according to the environmental monitoring temperature value.

[0052] like Figure 5 As shown, preferably, the step of controlling the switch of the heating mechanism according to the environmental monitoring temperature value includes:

[0053] S501, obtaining an initial monitoring temperature value of the temperature monitoring mechanism;

[0054] S502, determining whether the initial monitoring temperature value is greater than a first preset temperature value, if it is determined to be yes, turning on the heating mechanism for heating, if it is determined to be no, not turning on the heating mechanism;

[0055] S503, during the heating process, obtaining a real-time heating monitoring temperature value of the temperature detection mechanism;

[0056] S504, determining whether the real-time heating monitoring temperature value is greater than a second preset temperature value, and if so, turning off the heating mechanism, and if not, keeping the heating mechanism turned on;

[0057] S505, during the closing process, obtaining a real-time monitoring temperature value of the temperature detection mechanism;

[0058] S506, determining whether the real-time monitored temperature value is less than a third preset temperature value, wherein the third preset temperature value is greater than the first preset temperature value and less than the second preset temperature value, if the determination is yes, then re-enabling the heating mechanism, and if the determination is no, then keeping the heating mechanism in an off state;

[0059] S507, when the ventilation mechanism is turned off, the heating mechanism is also turned off.

[0060] It should be noted that in this embodiment, when the fresh air delivery is turned on, the system will collect the current ambient temperature as the initial monitoring temperature value to determine whether to turn on the heating mechanism. When the initial monitoring temperature is less than T1 °C, the heating mechanism will be automatically turned on, so that the user will not feel cold when using the toilet; after the heating mechanism is turned on, there is a temperature difference between the temperature detection area of the temperature monitoring mechanism and the area where the human body is located (because the temperature monitoring mechanism is arranged on the heating mechanism. Relatively speaking, when the heating mechanism is turned on, due to insufficient air flow, the temperature monitored by the temperature monitoring mechanism is higher than the temperature of the area where the human body is located; in addition, at the beginning, since the heating mechanism was kept closed before, the air flow was sufficient, so the temperature monitored by the temperature monitoring mechanism was basically the same as the temperature of the human body area). Therefore, during the heating process, when the temperature monitored by the temperature monitoring mechanism is greater than T2 °C, the heating mechanism will be automatically turned off, and during the closing process, when the temperature monitored by the temperature monitoring mechanism gradually drops to T3 °C (where T1 < T3 < T2), the warm air will be automatically turned on again, and so on in a cycle until the fresh air delivery is turned off. By adopting this embodiment, the on / off of the heating mechanism can be controlled according to the real-time temperature monitoring signal value, solving the discomfort during toilet use in cold weather.

[0061] As Figure 6 shown, preferably, the fresh air delivery method based on intelligent toilet odor monitoring further includes:

[0062] S601, obtaining and identifying the user's identity information;

[0063] S602, judging whether the user has set the first preset signal value, the second preset signal value, the third preset signal value, the first preset temperature value, the second preset temperature value, and the third preset temperature value according to the identity information,

[0064] S603, if the judgment is yes, driving the ventilation mechanism according to the corresponding first preset signal value, second preset signal value, and third preset signal value, and driving the heating mechanism according to the corresponding first preset temperature value, second preset temperature value, and third preset temperature value,

[0065] S604, if the judgment is no, reminding the user to make custom settings or default settings.

[0066] It should be noted that, in the present embodiment, the identity information of the user is identified by the identity identification mechanism (the identity identification mechanism pre-stores the user's identity information and the first preset signal value, the second preset signal value, the third preset signal value, the first preset temperature value, the second preset temperature value and the third preset temperature value corresponding to the identity information, that is, each user has different requirements for the heating temperature and the air exchange speed), and the corresponding first preset signal value, the second preset signal value, the third preset signal value, the first preset temperature value, the second preset temperature value and the third preset temperature value are selected according to the corresponding identity information to realize personalized automatic control and improve the convenience of use.

[0067] like Figure 7 As shown, the present invention also provides a fresh air delivery device based on smart toilet odor monitoring, which is used to implement the above-mentioned fresh air delivery method based on smart toilet odor monitoring, including a ventilation mechanism 1 and an odor monitoring mechanism 2 arranged on the smart toilet; the odor monitoring mechanism 2 is used to obtain the odor signal value around the smart toilet, and is used to determine whether the odor signal value is greater than a first preset signal value. When it is determined to be yes, a driving voltage signal is generated according to the odor signal value and the driving voltage signal is sent to the ventilation mechanism 1. When it is determined to be no, the ventilation mechanism 1 is not driven; the ventilation mechanism 1 is used to ventilate according to the driving voltage signal, wherein the operating rate of the ventilation mechanism 1 decreases as the odor signal value becomes smaller.

[0068] The present invention controls the operating rate of the ventilation mechanism according to the odor signal value around the smart toilet, wherein the operating rate of the ventilation mechanism decreases as the odor signal value decreases. The larger the odor signal value, the more odorous gases there are in the air, and the faster the operating rate of the ventilation mechanism is, so that the odorous gases are discharged at a faster speed; as the odorous gases are continuously discharged, the monitored odor signal value becomes smaller and smaller, which means that there are fewer odorous gases in the air, and the operating rate of the ventilation mechanism is smaller at this time, so that the operating noise of the ventilation mechanism is slowly and automatically reduced, and there is no need to manually adjust the ventilation mechanism, thereby improving the convenience of use of the ventilation mechanism.

[0069] Specifically, the operating rate of the ventilation mechanism satisfies: ν = S 气 *K, where ν is the operating speed of the ventilation mechanism, S 气 is the odor signal value, K is the ventilation constant. It is determined whether the odor signal value is greater than the second preset signal value, and the second preset signal value is greater than the first preset signal value. If it is determined to be yes, the operation rate of the ventilation mechanism satisfies: ν = S 气 *(S 气 / S2)*K, where ν is the operating speed of the ventilation mechanism, S 气is the odor signal value, S2 is the second preset signal value, K is the ventilation constant, and when the judgment is no, the operation rate of the ventilation mechanism satisfies: ν = S 气 *K, where ν is the operating speed of the ventilation mechanism, S 气 is the odor signal value, and K is the ventilation constant.

[0070] It should be noted that the operating rate of the ventilation mechanism is proportional to the odor signal value, and the ventilation constant is related to the structure of the ventilation mechanism. The ventilation mechanism can be operated at a continuous rate to avoid noise and system instability caused by excessive rate changes.

[0071] In addition, by judging whether the odor signal value is greater than the second preset signal value, the calculation formula for the operation rate of the ventilation mechanism is selected, that is, when the odor signal value is greater than the second preset signal value, the operation rate of the ventilation mechanism satisfies: ν = S 气 *(S 气 / S2)*K, where ν is the operating speed of the ventilation mechanism, S 气 is the odor signal value, S2 is the second preset signal value, and K is the ventilation constant; otherwise, the operating rate of the ventilation mechanism satisfies: ν=S 气 *K, where ν is the operating speed of the ventilation mechanism, S 气 is the odor signal value, and K is the ventilation constant. When the odor signal value is large, the operation rate change rate of the ventilation mechanism is larger, and becomes smaller as the odor signal value becomes smaller, thereby exhausting the odorous air in the bathroom at a faster speed.

[0072] like Figure 8As shown, preferably, the fresh air delivery device based on the odor monitoring of the intelligent toilet further includes: a heating mechanism 3 electrically connected to the ventilation mechanism 1 for heating the indoor air according to the ambient monitoring temperature value. A temperature monitoring mechanism 4 provided on and electrically connected to the heating mechanism 3 for obtaining the ambient monitoring temperature value. Specifically, while obtaining the odor signal value around the intelligent toilet, the ambient monitoring temperature value of the temperature monitoring mechanism is obtained, and the switch of the heating mechanism is controlled according to the ambient monitoring temperature value. The step of controlling the switch of the heating mechanism according to the ambient monitoring temperature value includes: obtaining the initial monitoring temperature value of the temperature monitoring mechanism; determining whether the initial monitoring temperature value is greater than the first preset temperature value. If it is determined to be yes, the heating mechanism is turned on for heating. If it is determined to be no, the heating mechanism is not turned on; during the heating process, obtaining the real-time heating monitoring temperature value of the temperature detection mechanism; determining whether the real-time heating monitoring temperature value is greater than the second preset temperature value. If it is determined to be yes, the heating mechanism is turned off. If it is determined to be no, the heating mechanism is kept turned on; during the closing process, obtaining the real-time monitoring temperature value of the temperature detection mechanism; determining whether the real-time monitoring temperature value is less than the third preset temperature value, where the third preset temperature value is greater than the first preset temperature value and less than the second preset temperature value. If it is determined to be yes, the heating mechanism is restarted. If it is determined to be no, the heating mechanism is kept turned off; when the ventilation mechanism is turned off, the heating mechanism is also turned off.

[0073] It should be noted that in this embodiment, when the fresh air delivery is turned on, the system will collect the current ambient temperature as the initial monitoring temperature value to determine whether to turn on the heating mechanism. When the initial monitoring temperature is less than T1 °C, the heating mechanism will be automatically turned on, so that the user will not feel cold when using the toilet; after the heating mechanism is turned on, there is a temperature difference between the temperature detection area of the temperature monitoring mechanism and the area where the human body is located (because the temperature monitoring mechanism is provided on the heating mechanism. Relatively speaking, when the heating mechanism is turned on, due to insufficient air flow, the temperature monitored by the temperature monitoring mechanism is higher than the temperature of the area where the human body is located; in addition, at the beginning, since the heating mechanism was kept turned off before, the air flow was sufficient, so the temperature monitored by the temperature monitoring mechanism was basically the same as the temperature of the human body area). Therefore, during the heating process, when the temperature monitored by the temperature monitoring mechanism is greater than T2 °C, the heating mechanism will be automatically turned off, and during the closing process, when the temperature monitored by the temperature monitoring mechanism gradually decreases to T3 °C (where T1 < T3 < T2), the warm air will be automatically turned on again, and so on until the fresh air delivery is turned off. By adopting this embodiment, the switch of the heating mechanism can be controlled according to the real-time temperature monitoring signal value, solving the discomfort during toilet use in cold weather.

[0074] Furthermore, the fresh air delivery device based on the smart toilet odor monitoring also includes: a reminder mechanism 5, which is used to issue an audible and visual warning to remind the user to stay away and is electrically connected to the odor monitoring mechanism 2; an identity recognition mechanism 6, which is used to obtain and identify the user's identity information and is electrically connected to the heating mechanism 3 and the odor monitoring mechanism 2. Specifically, when the odor signal value is greater than the third preset signal value, wherein the third preset signal value is greater than the second preset signal value; if it is judged to be yes, the reminder mechanism is used to issue an audible and visual warning to remind the user to stay away; if it is judged to be no, it is not issued. The identity recognition mechanism is used to obtain and identify the user's identity information, and judge whether the user has set the first preset signal value, the second preset signal value, the third preset signal value, the first preset temperature value, the second preset temperature value and the third preset temperature value according to the identity information. If it is judged to be yes, the ventilation mechanism is driven according to the corresponding first preset signal value, the second preset signal value and the third preset signal value, and the heating mechanism is driven according to the corresponding first preset temperature value, the second preset temperature value and the third preset temperature value. If it is judged to be no, the user is reminded to make custom settings or default settings.

[0075] It should be noted that whether to remind the user to stay away is determined by judging whether the odor signal value is greater than the third preset signal value, that is, when the odor signal value is greater than the second preset signal value, an audible and visual warning is issued to remind the user to stay away; otherwise, no audible and visual warning is issued. With this embodiment, when the odor signal value is very large, it indicates that it is not suitable for the human body to stay for a long time, so it is necessary to issue an audible and visual warning to remind the user to stay away to avoid safety hazards.

[0076] In addition, the identity information of the user is identified by the identity identification mechanism (the identity identification mechanism pre-stores the user's identity information and the first preset signal value, the second preset signal value, the third preset signal value, the first preset temperature value, the second preset temperature value and the third preset temperature value corresponding to the identity information, that is, each user has different requirements for the heating temperature and the air exchange speed), and the corresponding first preset signal value, the second preset signal value, the third preset signal value, the first preset temperature value, the second preset temperature value and the third preset temperature value are selected according to the corresponding identity information to realize personalized automatic control and improve the convenience of use.

[0077] like Fig. 9As shown, the ventilation mechanism 1 includes a ventilation module 11, a driving module 12, a first control module 13, a first communication module 14 and a first power supply module 15, the first power supply module 15, the driving module 12 and the first communication module 14 are all electrically connected to the first control module 13, the first communication module 14 is electrically connected to the first power supply module 15, and the driving module 12 is used to drive the ventilation module 11 to perform ventilation action; the odor monitoring mechanism 2 includes an odor monitoring module 21, a second control module 22, a second communication module 23 and a second power supply module 24, the odor monitoring module 21, the second control module 22 and the second communication module 23 are all electrically connected to the second power supply module 24, the odor monitoring module 21 and the second communication module 23 are both electrically connected to the second control module 22, the second communication module 23 communicates with the first communication module 14, and the odor monitoring module 21 is used to monitor air odor signals.

[0078] It should be noted that the ventilation and fresh air system linked to the smart toilet includes but is not limited to heaters, adjustable speed exhaust fans, bathroom heaters and other devices with fresh air. The first control module and the second control module are both single-chip microcomputers, and the first power supply module and the second power supply module are both lithium batteries or power adapters, but are not limited to this. The single-chip microcomputer integrates many components such as an arithmetic unit, a controller, a memory, and an input and output device to realize many functions such as signal processing and data storage. For example, the arithmetic unit contains a large number of comparison circuits, which can perform logical operations on the received signal instructions. Preferably, the models that can be used for the above-mentioned single-chip microcomputer include but are not limited to PIC12F615.

[0079] In the present invention, when a user uses the smart toilet to go to the toilet, the odor monitoring mechanism 2 arranged on the smart toilet collects the air odor signal around the smart toilet in real time and transmits it to the second control module. When the air odor signal is greater than the preset threshold, the second control module calculates the driving voltage of the driving module according to the air odor signal (calculated by the built-in operator of the single-chip microcomputer, and the calculation formula is preset), and transmits the driving voltage to the first control module through the second communication module and the first communication module. The first control module drives the driving module according to the driving voltage to drive the ventilation module to run at a certain rate to achieve the purpose of ventilation; accordingly, the larger the air odor signal, the larger the driving voltage, and the faster the fresh air adjustment is performed. When the air odor signal slowly decreases, the ventilation speed will also slowly decrease, thereby achieving the effect of intelligent adjustment. Therefore, the user does not need to manually turn on the ventilation function during the toilet process, and can reduce the noise interference of the exhaust fan running at full speed, and also discharge the odor to the greatest extent, so that the user has a quiet and comfortable environment in the bathroom, and the experience is better.
