Detailed Description
The following is further detailed by the specific embodiments:
the first embodiment is as follows:
the embodiment of the invention discloses an intelligent fragrance diffusing device based on internet of things parameter acquisition, as shown in fig. 1: the perfume box comprises perfume, a perfume box for placing the perfume and a heating unit arranged at the bottom of the perfume box and used for radiating heat, wherein the bottom of the perfume box is provided with air holes which are vertically arranged in a penetrating way; further comprising:

and the concentration control unit is used for controlling the working state of the heating unit and/or the blowing unit according to the indoor environment parameters so as to adjust the fragrance concentration emitted by the perfume.
In this embodiment, with reference to fig. 2: the intelligent fragrance dispersing device comprises a shell 1 with an opening at the top, a fragrance box 2 arranged at the top of the shell 1, a heating unit 4 arranged in the shell 1 and positioned below the fragrance box 2 and used for dispersing heat, an air blowing unit 5 arranged in the shell 1 and positioned below the heating unit 4 and used for conveying air to the bottom of the fragrance box 2, and a concentration control unit 6 arranged in the shell 1; a temperature sensor 7 and a humidity sensor 8 are fixedly provided on the outer peripheral side portion of the housing 1. A plurality of air inlets 11 for air to enter the shell 1 are arranged on the peripheral side part of the shell 1; spice 3 is arranged on the spice box 2, and the bottom of the spice box 2 is provided with a vent hole 21 which is vertically arranged in a through way.
In this embodiment, the heating unit 4 is a heating metal sheet capable of emitting heat; the blowing unit 5 is an existing fan assembly; the temperature sensor 7 and the humidity sensor 8 are both existing sensors of the internet of things; the concentration control is a microprocessor which can calculate and process temperature data and humidity data and can control the heating metal sheet and the fan assembly to work; the spice 3 is an existing sachet, incense wood or other solid spice 3.
In the actual working process, the heating unit emits heat at the bottom of the spice box to assist the spice to emit fragrance, meanwhile, the gas conveyed to the bottom of the spice box by the blowing unit can be heated by the heating unit to form hot gas flow, and the hot gas flow can better assist the spice to emit fragrance; the higher the heating temperature of the heating unit is, the higher the fragrance emission concentration of the perfume can be, and the hot air flow has better effect than the direct heating mode. According to the invention, the indoor environment data of the indoor environment in which the internet of things unit is located is collected, and the concentration control unit takes the indoor environment data as the control condition for controlling the working states of the heating unit and the blowing unit, so that the fragrance emitting device can adaptively adjust the fragrance emitting speed and concentration according to the indoor environment parameters (factors), and continuous, stable and balanced fragrance emitting control is realized, and the fragrance emitting effect of the perfume can be improved.
In the specific implementation process, the indoor environment parameters comprise indoor space area values;
the concentration control unit is used for controlling the heating unit and the blowing unit to corresponding working states according to the indoor space area value, and the specific process is as follows: and respectively comparing the indoor space area value with the plurality of area value intervals to obtain the area value interval to which the indoor space area value belongs, then obtaining a concentration control scheme corresponding to the area value interval, and controlling the working states of the heating unit and the blowing unit according to the concentration control scheme.
In the practical process, the applicant finds that the fragrance concentration of the fragrance with the same volume in indoor environments with different space areas is different, namely, the space area of the indoor environment where the fragrance emitting device is located influences the transmission effect of fragrance molecules. Therefore, the present embodiment uses the indoor space area value as the control condition for controlling the fragrance concentration, that is, the present embodiment obtains the preset concentration control scheme according to the indoor space area value to control the heating unit and the blowing unit, so that the fragrance concentration corresponds to the size of the indoor space area, which is beneficial for the fragrance emitting device to emit fragrance with proper concentration. Specifically, the indoor space area value is manually input by a user.
In a specific implementation process, the area value interval comprises: square meter 1, square meter 50, square meter 51, square meter 100, square meter 101, square meter 150, square meter 151 and square meter 200.
In the actual working process, the influence of the size of the space area on the fragrance concentration is not very obvious, namely, the fragrance concentration only needs to be adjusted when the space area is greatly different. Therefore, every 50 square meters in the invention corresponds to a concentration control scheme, namely, the fragrance concentration is adjusted once every difference of indoor space area value by 50 square meters, thus the requirement of space area for fragrance concentration can be better met, and the fragrance emitting device can be assisted to emit fragrance with proper concentration. Of course, the size of the area value interval may be adjusted according to the requirement in actual implementation, or more area value intervals may be set.
In the specific implementation process, the heating unit has a high-temperature state, a constant-temperature state and a heating stop state;
the concentration control scheme of an area value interval [1 square meter, 50 square meters ] is as follows: controlling the heating unit to be in a constant temperature state, and controlling the blowing unit to stop working; the concentration control scheme of an area value interval [51 square meters and 100 square meters ] is as follows: controlling the heating unit to be in a constant temperature state, and controlling the blowing unit to work; the concentration control scheme of an area value interval [101 square meters and 150 square meters ] is as follows: controlling the heating unit to be in a high-temperature state, and controlling the blowing unit to stop working; the concentration control scheme of an area value interval [151 square meters and 200 square meters ] is as follows: and controlling the heating unit to be in a high-temperature state and controlling the blowing unit to work.
In the actual working process, the higher the heating temperature of the heating unit is, the higher the fragrance emission concentration of the perfume can be, and the hot air flow has better effect than a direct heating mode. Therefore, the heating temperature of the heating unit and the working state of the air blowing unit are correspondingly controlled according to the indoor space area value, so that the fragrance concentration can be better adapted to the indoor space area value.
In the specific implementation process, the indoor environment parameters further comprise indoor temperature values; the heating unit has a high-temperature state, a constant-temperature state and a heating stop state;
the concentration control unit is used for adjusting the working state of the heating unit according to the indoor temperature value, and the specific process is as follows: comparing the indoor temperature value with a set minimum temperature threshold and a set maximum temperature threshold, and if the indoor temperature value is less than or equal to the minimum temperature threshold, controlling the heating unit to be in a high-temperature state; if the indoor temperature value is greater than or equal to the highest temperature threshold value, controlling the heating unit to a heating stop state; and if the indoor temperature value is greater than the lowest temperature threshold and less than the highest temperature threshold, controlling the heating unit to be in a constant temperature state.
In the actual working process, the applicant finds that under the condition of the same fragrance concentration, the higher the indoor temperature is, the more the fragrance molecules move, and the more the fragrance molecules are sensed by people; also, the indoor temperature has a greater effect on the activity and transmission of fragrance molecules than the area of the indoor space. Therefore, on the basis of obtaining the indoor space area value, the indoor temperature value is further obtained, and the working state of the heating unit is adjusted based on the indoor temperature value, so that on one hand, the fragrance concentration can be better adapted to indoor environmental factors, namely, the fragrance emission effect of the fragrance is favorably improved; on the other hand, after the heating temperature of heating element is adjusted, heating element itself can change the ambient temperature of indoor environment to a certain extent, and heating element can assist the ambient temperature who improves the environment promptly, promotes the temperature comfort level of the environment of locating.
In the specific implementation process, the lowest temperature threshold is 18 ℃, and the highest temperature threshold is 24 ℃; the high temperature state of the heating unit means that the heating temperature is higher than 35 ℃, and the constant temperature state of the heating unit means that the heating temperature is between 25 ℃ and 35 ℃.
Applicants have found that 18 ℃ to 24 ℃ is the most comfortable ambient temperature. Therefore, the lowest temperature threshold is set to be 18 ℃, the highest temperature threshold is set to be 24 ℃, and when the indoor temperature value is 18-24 ℃, the heating unit (when the auxiliary spice emits the fragrance) can avoid influencing the indoor environment temperature to a certain extent, so that the most comfortable environment temperature can be kept in the auxiliary indoor environment; when the indoor environment temperature is too high or too low, the heating unit can assist the indoor environment to adjust and improve the environment temperature. In addition, the heating temperature in the high-temperature state and the heating temperature in the constant-temperature state are both favorable for assisting the perfume to emit fragrance. Of course, in actual implementation, the values of the minimum temperature threshold and the maximum temperature threshold may be adjusted according to requirements, or the heating temperatures of the heating unit in the high-temperature state and the constant-temperature state may be adjusted.
In the specific implementation process, the indoor environment parameters also comprise an indoor humidity value; the intelligent fragrance diffusing device also comprises a steam generating unit arranged above the blowing unit, and the steam generating unit is used for generating steam;
the concentration control unit is used for adjusting or controlling the working states of the blowing unit and the steam generating unit according to the indoor humidity value, and the specific process is as follows: comparing the indoor humidity value with a set minimum humidity threshold value and a set maximum humidity threshold value, and controlling the blowing unit and the steam generating unit to work if the indoor humidity value is less than or equal to the minimum humidity threshold value; if the indoor humidity value is greater than or equal to the maximum humidity threshold value, controlling the blowing unit and the steam generating unit to stop working; and if the indoor humidity value is greater than the minimum humidity threshold and less than the maximum humidity threshold, controlling the blowing unit to work and controlling the steam generating unit to stop working.
In the actual working process, the applicant finds that under the condition of the same fragrance concentration, the higher the indoor humidity is, the more the fragrance molecules move, and the more the fragrance molecules are perceived by people; also, the indoor humidity has a greater effect on the activity and transmission of fragrance molecules than the area of the indoor space. Therefore, on the basis of obtaining the indoor space area value, the indoor humidity value is further obtained, and the working states of the blowing unit and the steam generating unit are adjusted based on the indoor humidity value, so that on one hand, the fragrance concentration can be better adapted to indoor environmental factors, namely, the fragrance emission effect of the perfume is favorably improved; on the other hand, when the indoor humidity of the indoor environment is too low, the blowing unit and the steam generating unit can generate 'water steam carrying with fragrance molecules' so as to improve the indoor humidity while adjusting the fragrance concentration, and therefore, the humidity comfort degree of the indoor environment is improved.
In the specific implementation process, the lowest humidity threshold is 40% RH, and the highest humidity threshold is 70% RH.
Applicants have found that 40% RH to 70% RH is the most comfortable humidity environment.

Since both the indoor temperature and the indoor humidity have a great influence on the activity and the transmission effect of fragrance molecules, and the indoor temperature and the indoor humidity are themselves correlated with each other, the indoor temperature and the indoor humidity should be combined as a control condition to control the fragrance concentration. In addition, the applicant found in experiments that, under the same fragrance concentration condition, the activity and the transmission effect of fragrance molecules in an environment with higher humidity (suitable temperature) are higher than those in an environment with higher temperature (suitable humidity), that is, the influence of indoor humidity on the activity and the transmission effect of fragrance molecules is higher than that of indoor temperature.
Based on the above findings, the applicant proposes the following solutions:
specifically, the indoor environment parameters further include an indoor temperature value and an indoor humidity value; the heating unit has a high-temperature state, a constant-temperature state and a heating stop state;
the concentration control unit is also used for adjusting the working state of the heating unit according to the indoor temperature value and the indoor humidity value, and the specific process is as follows: comparing the indoor temperature value with a set lowest temperature threshold value and a set highest temperature threshold value, and comparing the indoor humidity value with a set lowest humidity threshold value and a set highest humidity threshold value; if the indoor temperature value is less than or equal to the lowest temperature threshold value and the indoor humidity value is less than or equal to the lowest humidity threshold value, controlling the heating unit to be in a high-temperature state; if the indoor temperature value is greater than or equal to the maximum temperature threshold value and the indoor humidity value is greater than or equal to the maximum humidity threshold value, controlling the heating unit to be in a heating stop state; if the indoor humidity value is larger than the lowest humidity threshold value and smaller than the highest humidity threshold value, controlling the heating unit to be in a constant temperature state;
if the indoor humidity value is less than or equal to the lowest humidity threshold value and the indoor temperature value is greater than the lowest temperature threshold value, according to a formula I:
Figure BDA0003067144240000081
calculating to obtain a low humidity comprehensive value z1And making the following judgment: if z is1If the temperature is less than or equal to 1, controlling the heating unit to be in a high temperature state; if 1 < z1Controlling the heating unit to be in a constant temperature state when the temperature is less than or equal to 1.5 ℃; if z is1If the temperature is more than 1.5, controlling the heating unit to be in a heating stop state;
if the indoor humidity value is greater than or equal to the maximum humidity threshold value and the indoor temperature value is less than the maximum temperature threshold value, according to a second formula:
Figure BDA0003067144240000091
calculating to obtain a high humidity comprehensive value z2And making the following judgment: if z is2If the temperature is more than or equal to 1, controlling the heating unit to be in a heating stop state; if z is 0.8 or less2If the temperature is less than 1, controlling the heating unit to be in a constant temperature state; if z is2If the temperature is less than 0.8, controlling the heating unit to be in a high-temperature state;

According to the invention, the indoor temperature value and the indoor humidity value are simultaneously obtained, and the indoor temperature value and the indoor humidity value are combined to be used as a control condition, so that the fragrance emission effect of the perfume can be better improved. Meanwhile, when the influence of the indoor temperature value and the indoor humidity value on the fragrance concentration is inconsistent, the low humidity comprehensive value and the high humidity comprehensive value are respectively obtained by calculation according to the first formula and the second formula, and the corresponding concentration control scheme is obtained by a comparison and judgment mode, and in the first formula and the second formula, the weight occupied by the indoor humidity value is obviously greater than the indoor temperature value (the coefficient of the indoor humidity value is greater), namely, the problem that the influence of the indoor humidity on the activity and the propagation effect of fragrance molecules is greater than the indoor temperature is considered in the invention, so that the fragrance concentration control effect of the fragrance dispersing device is better when the indoor temperature value and the indoor humidity value are combined as the control condition.
