Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings. It is only noted that the invention is intended to be limited to the specific forms set forth herein, including any reference to the drawings, as well as any other specific forms of embodiments of the invention.

As shown in fig. 1, the invention provides a fresh air conveying method based on intelligent toilet odor monitoring, which comprises the following steps:

s101, acquiring odor signal values around the intelligent closestool;

s102, judging whether the odor signal value is larger than a first preset signal value or not,

s103, if yes, generating a driving voltage signal according to the odor signal value and sending the driving voltage signal to a ventilation mechanism to drive the ventilation mechanism to ventilate, wherein the operation rate of the ventilation mechanism is reduced along with the reduction of the odor signal value;

and S104, if the judgment result is no, the ventilation mechanism is not driven.

According to the invention, the operation rate of the ventilation mechanism is controlled according to the odor signal value around the intelligent closestool, wherein the operation rate of the ventilation mechanism is reduced as the odor signal value becomes smaller. The larger the odor signal value is, the more the odor gas in the air is, and the higher the operation speed of the ventilation mechanism is, so that the odor gas can be exhausted at a higher speed; along with the continuous discharge of the odor, the monitored odor signal value is smaller and smaller, which indicates that the odor in the air is less, and the operation speed of the air exchange mechanism is smaller, so that the operation noise of the air exchange mechanism is slowly and automatically reduced, the air exchange mechanism does not need to be adjusted in a manual mode, and the use convenience of the air exchange mechanism is improved.

Preferably, the operating rate of the ventilation mechanism satisfies: v ═ S_{Qi (Qi)}K, where v is the operating rate of the ventilation mechanism, S_{Qi (Qi)}K is the ventilation constant for the odor signal value.

It should be noted that the operation 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 the embodiment, the air exchange mechanism can work at a continuous speed, and the noise and the instability of the system caused by overlarge speed change are avoided.

s203, when the judgment result is no, the operation speed of the ventilation mechanism satisfies the following conditions: v ═ S_{Qi (Qi)}K, where v is the operating rate of the ventilation mechanism, S_{Qi (Qi)}K is the ventilation constant for the odor signal value.

It should be noted that, by determining whether the odor signal value is greater than a second preset signal value, a calculation formula of the operation rate of the ventilation mechanism is selected, that is: when the odor signal value is larger than a second preset signal value, the operation speed of the air exchange mechanism meets the following conditions: v ═ S_{Qi (Qi)}*(S_{Qi (Qi)}/S₂) K, where v is the operating rate of the ventilation mechanism, S_{Qi (Qi)}For said odor signal value, S₂The value is the second preset signal value, and K is a ventilation constant; otherwise, the operation speed of the air exchange mechanism meets the following conditions: v ═ S_{Qi (Qi)}K, where v is the operating rate of the ventilation mechanism, S_{Qi (Qi)}K is the ventilation constant for the odor signal value. With the present embodiment, when the odor signal value is larger, the operating rate change rate of the ventilation mechanism is larger, and is smaller as the odor signal value is smaller, so that the odor air in the toilet can be discharged at a faster speed.

As shown in fig. 3, preferably, the fresh air delivery method based on intelligent toilet odor monitoring further includes:

s301, judging whether the odor signal value is larger than a third preset signal value, wherein the third preset signal value is larger than the second preset signal value;

s302, when the judgment result is yes, an audible and visual alarm is sent to remind the user of going away;

and S303, if the judgment result is no, the data is not sent out.

It should be noted that whether the user is reminded to get away is selected by judging whether the odor signal value is larger than a third preset signal value, that is: when the odor signal value is larger than a second preset signal value, emitting an acousto-optic alarm to remind a user of going away; otherwise it is not issued. Adopt this embodiment, when smell signal value is very big, show that it is not suitable for the human body to stay for a long time, consequently need avoid taking place the potential safety hazard through sending acousto-optic warning in order to remind the user to keep away from.

s503, acquiring a real-time heating monitoring temperature value of the temperature detection mechanism in the heating process;

s504, judging whether the real-time heating monitoring temperature value is larger than a second preset temperature value, if so, closing the heating mechanism, and if not, keeping the heating mechanism in an opening state;

s505, in the closing process, acquiring a real-time monitoring temperature value of the temperature detection mechanism;

s506, judging whether the real-time monitoring temperature value is smaller than a third preset temperature value, wherein the third preset temperature value is larger than the first preset temperature value and smaller than a second preset temperature value, restarting the heating mechanism if the third preset temperature value is judged to be larger than the first preset temperature value, and keeping the closing state of the heating mechanism if the third preset temperature value is judged to be not larger than the second preset temperature value;

and S507, when the ventilation mechanism is closed, the heating mechanism is also closed.

It should be noted that, in this embodiment, when the fresh air transportation is started, the system collects the current ambient temperature as an initial monitoring temperature value to determine whether to start the heating mechanism, and when the initial monitoring temperature is lower than T1 ℃, the heating mechanism is automatically started, so that a user does not feel cold when using the toilet; after the heating mechanism is started, because the temperature difference exists 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 started, the temperature monitored by the temperature monitoring mechanism needs to be higher than the temperature of the area where the human body is located because the air flow is insufficient, and in addition, at the beginning, because the heating mechanism is kept in a closed state before the heating mechanism is in a sufficient state, the temperature monitored by the temperature monitoring mechanism is basically consistent with the temperature of the area where the human body is located, in the heating process, when the temperature monitored by the temperature monitoring mechanism is higher than T2 ℃, the heating mechanism is automatically closed, and in the closing process, when the temperature monitored by the temperature monitoring mechanism is gradually reduced to T3 ℃ (T1 < T3< T2), the warm air is automatically opened again, and the circulation is carried out, until the fresh air supply is closed. By adopting the embodiment, the switch of the heating mechanism can be controlled according to the real-time temperature monitoring signal value, and the problem of uncomfortable feeling of using the toilet in cold weather is solved.

It should be noted that, in this embodiment, the identity information of the user is recognized by the identity recognition mechanism (the identity recognition mechanism prestores the identity information of the user and a first preset signal value, a second preset signal value, a third preset signal value, a first preset temperature value, a second preset temperature value, and a 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 corresponding second preset signal value, the corresponding third preset signal value, the corresponding first preset temperature value, the corresponding second preset temperature value, and the corresponding third preset temperature value are selected according to the corresponding identity information, so that personalized automatic control is realized, and convenience in use is improved.

As shown in fig. 7, the invention further provides a fresh air conveying device based on intelligent toilet odor monitoring, which is used for implementing the fresh air conveying method based on intelligent toilet odor monitoring, and comprises a ventilation mechanism 1 and an odor monitoring mechanism 2 arranged on the intelligent toilet; the odor monitoring mechanism 2 is used for acquiring an odor signal value around the intelligent closestool and judging whether the odor signal value is larger than a first preset signal value, if so, generating a driving voltage signal according to the odor signal value and sending the driving voltage signal to the ventilation mechanism 1, and if not, not driving the ventilation mechanism 1; the ventilation mechanism 1 is used for ventilation according to the driving voltage signal, wherein the operation speed of the ventilation mechanism 1 is reduced as the odor signal value becomes smaller.

According to the invention, the operation rate of the ventilation mechanism is controlled according to the odor signal value around the intelligent closestool, wherein the operation rate of the ventilation mechanism is reduced as the odor signal value becomes smaller. The larger the odor signal value is, the more the odor gas in the air is, and the higher the operation speed of the ventilation mechanism is, so that the odor gas can be exhausted at a higher speed; along with the continuous discharge of the odor, the monitored odor signal value is smaller and smaller, which indicates that the odor in the air is less, and the operation speed of the air exchange mechanism is smaller, so that the operation noise of the air exchange mechanism is slowly and automatically reduced, the air exchange mechanism does not need to be adjusted in a manual mode, and the use convenience of the air exchange mechanism is improved.

Specifically, the operation rate of the air exchange mechanism satisfies the following conditions: v ═ S_{Qi (Qi)}K, where v is the operating rate of the ventilation mechanism, S_{Qi (Qi)}K is the ventilation constant for the odor signal value. Judging whether the odor signal value is larger than a second preset signal value or not, wherein the second preset signal value is largeWhen the first preset signal value is judged to be yes, the operation speed of the air exchange mechanism meets the following requirements: v ═ S_{Qi (Qi)}*(S_{Qi (Qi)}/S₂) K, where v is the operating rate of the ventilation mechanism, S_{Qi (Qi)}For said odor signal value, S₂And if the second preset signal value is positive, K is a ventilation constant, and if the judgment result is negative, the operation speed of the ventilation mechanism meets the following requirements: v ═ S_{Qi (Qi)}K, where v is the operating rate of the ventilation mechanism, S_{Qi (Qi)}K is the ventilation constant for the odor signal value.

It should be noted that the operation 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 air exchange mechanism can work at a continuous speed, and noise and system instability caused by excessive speed change are avoided.

In addition, a calculation formula of the operation speed of the ventilation mechanism is selected by judging whether the odor signal value is larger than a second preset signal value, namely: when the odor signal value is larger than a second preset signal value, the operation speed of the air exchange mechanism meets the following conditions: v ═ S_{Qi (Qi)}*(S_{Qi (Qi)}/S₂) K, where v is the operating rate of the ventilation mechanism, S_{Qi (Qi)}For said odor signal value, S₂The value is the second preset signal value, and K is a ventilation constant; otherwise, the operation speed of the air exchange mechanism meets the following conditions: v ═ S_{Qi (Qi)}K, where v is the operating rate of the ventilation mechanism, S_{Qi (Qi)}K is the ventilation constant for the odor signal value. When the odor signal value is larger, the change rate of the operation speed of the air exchange mechanism is larger, and is smaller along with the smaller odor signal value, so that the odor air in the toilet is discharged at a faster speed.

It should be noted that, in this embodiment, when the fresh air transportation is started, the system collects the current ambient temperature as an initial monitoring temperature value to determine whether to start the heating mechanism, and when the initial monitoring temperature is lower than T1 ℃, the heating mechanism is automatically started, so that a user does not feel cold when using the toilet; after the heating mechanism is started, because the temperature difference exists 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 started, the temperature monitored by the temperature monitoring mechanism needs to be higher than the temperature of the area where the human body is located because the air flow is insufficient, and in addition, at the beginning, because the heating mechanism is kept in a closed state before the heating mechanism is in a sufficient state, the temperature monitored by the temperature monitoring mechanism is basically consistent with the temperature of the area where the human body is located, in the heating process, when the temperature monitored by the temperature monitoring mechanism is higher than T2 ℃, the heating mechanism is automatically closed, and in the closing process, when the temperature monitored by the temperature monitoring mechanism is gradually reduced to T3 ℃ (T1 < T3< T2), the warm air is automatically opened again, and the circulation is carried out, until the fresh air supply is closed.
