[0022] The preset pressure enables the two-fluid atomizing nozzle to spray the atomized essential oil quickly to the relative position of the target object, and the preset flow rate enables the concentration of the essential oil in the area where the target object is located to always be within a preset range.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Figure 1 Schematic diagram of the structure of an aromatherapy machine according to an embodiment of the present invention.

[0047] The embodiment of the present invention only describes the necessary structure and corresponding improved structure of the aromatherapy machine, and the remaining implementation structures can refer to the prior art.

[0048] Specifically, an embodiment of the present invention provides an aromatherapy machine, which includes a position sensing module, a concentration sensing module, a two-fluid atomizing nozzle, an air pressure boosting module, an essential oil module, a nozzle posture adjustment module and a central control module.

[0049] The position sensing module is used to obtain relative position information of the target object (or target user) relative to the aromatherapy machine, and the relative position information includes relative direction information and relative distance information of the target object relative to the aromatherapy machine.

[0050] Specifically, the aroma diffuser needs to sense external objects through a position sensing module. In actual implementation, the implementation structure of the position sensing module is adjusted according to different external objects that need to be sensed.

[0051] Under the existing technology, based on implementation cost considerations, the position sensing module of an embodiment of the present invention includes: a human presence sensor for identifying the relative distance information between the target object and the aromatherapy machine; and a recording device matrix for identifying the relative direction information between the target object and the aromatherapy machine through the sound phase difference of the target object.

[0052] Specifically, the attached figure Figure 2 The working principle diagram of the position sensing module 20 according to the embodiment of the present invention is shown. Figure 2 The circle in the figure is the boundary line of the human body recognition interval of the human presence sensor, and the radius distance interval mark of the digital interval mark within the human body recognition interval is in meters.

[0053] Specifically, the human presence sensor under the existing technology is mainly implemented based on millimeter wave radar. The millimeter wave radar transmits FMCW and CW radio waves to the sensing area. The radio waves reflected by all moving, micro-moving, and extremely weak micro-moving targets in the sensing area are converted into electrical signals by the millimeter wave MMIC circuit in the sensor system. After the electrical signals are processed, the required human presence information is obtained.

[0054] In a home environment, in order to reduce manufacturing costs, the human presence sensor is only responsible for sensing whether a human body exists (i.e., it only determines whether a human body exists, but not the actual position). In actual implementation, the human presence sensor can adjust the working voltage so that the millimeter-wave radar can perform traversal detection of radius changes within the detection range at an extremely fast speed (limited by the adjustment technology, the minimum step of traversal detection is 0.8 meters in the embodiment of the present invention), thereby judging the distance between the human body and the human presence sensor through the structural difference between the front and rear detections.

[0055] It should be noted that the current mainstream technical solution for the implementation of human presence sensors is to add several shielding areas for the human presence sensors during the software setting stage. The energy fluctuations within the shielding areas will not trigger the triggering of the human presence sensors. The embodiments of the present invention can be understood as an improvement on the existing implementation methods.

[0056] Therefore, the relative distance information between the target user and the aromatherapy machine can be sensed through the human presence sensor; after knowing the relative distance information between the target user and the aromatherapy machine, it is only necessary to confirm the direction of the target relative to the aromatherapy machine to confirm the relatively accurate position between the target user and the aromatherapy machine.

[0057] In an embodiment of the present invention, the relative direction of the target user relative to the aromatherapy machine is obtained through a recording device matrix. Specifically, the implementation principle of the recording device matrix is ​​to obtain the sound information of the target user 21 through multiple recording devices, and determine the direction of the target user 21 relative to the aromatherapy machine through the phase difference of the sound obtained by the recording devices at different positions. In the specific implementation, the voiceprint recognition technology can be combined to screen the sound information that needs to be compared. In addition, the recording device matrix can also serve as a voice command input tool for the target user 21 to voice control the aromatherapy machine, thereby maximizing the reduction of the use cost of the aromatherapy machine.

[0058] The concentration sensing module is used to obtain the basic concentration information of the aromatherapy essential oil in the environment where the aromatherapy machine is located. Specifically, when the aromatherapy machine is working externally, part of the aromatherapy macromolecules are dissolved in the carrier solvent, and part of the aromatherapy macromolecules are freely diffused in the air in the form of macromolecules. The freely diffused aromatherapy macromolecules are the main source of the aromatherapy smell that the human body can feel, and the aromatherapy macromolecules dissolved in the carrier solvent will also be converted into freely diffused aromatherapy macromolecules within a certain period of time as the carrier solvent evaporates.

[0059] Therefore, measuring the basic concentration information of aromatherapy essential oils in the environment where the aromatherapy machine is located is actually detecting the concentration of aromatherapy macromolecules in the air. The detection object is actually gas, and a gas sensor is generally used to detect the concentration of aromatherapy macromolecules in the air.

[0060] Based on cost and volume considerations, the concentration sensing module generally uses a semiconductor gas sensor or a solid electrolyte gas sensor. Limited by the manufacturing cost, the gas sensor used in the concentration sensing module of the embodiment of the present invention is only developed for a single aromatherapy essential oil category, and is developed specifically for the different types of selected aromatherapy essential oils (special groups in macromolecules, such as carboxyl structure, hydroxyl structure, etc.). Generally, unlike conventional gas molecules such as oxygen and nitrogen in the air, aromatherapy macromolecules provide air sensors with relatively easy detection features due to the special nature of the groups; for example, a semiconductor gas sensor uses a detection element made of metal oxide or metal semiconductor oxide material, on which an adsorption circuit is arranged; the adsorption circuit uses a manufacturing material corresponding to the aromatherapy macromolecule, and when the adsorption circuit contacts the air, the aromatherapy macromolecule in the air will be adsorbed on the surface, which will cause the movement of carriers (electrons or holes) in the semiconductor, thereby causing changes in the semiconductor conductivity, volt-ampere characteristics or surface potential; by measuring these changes and finding the corresponding gas content information based on the calibration of components, the required aromatherapy essential oil basic concentration information is obtained.

[0061] The two-fluid atomizing nozzle is used to atomize the essential oil through airflow and output the atomized aromatherapy essential oil in the form of a jet. Figure 3The schematic diagram of the two-fluid atomizing nozzle structure is shown. The actual function of the two-fluid atomizing nozzle 10 is to introduce a first fluid with a high flow rate (generally a gas, and air in the embodiment of the present invention) and a second fluid with a low flow rate (generally a liquid, and aromatherapy essential oil in the embodiment of the present invention) from the corresponding first guide holes 11 and the second guide holes 12 into the atomizing cavity 13 inside the two-fluid atomizing nozzle, respectively. The first fluid and the second fluid generate pressure waves at different flow rates, so that the two are mixed and atomized in the atomizing cavity 13 (the liquid fluid is atomized into a droplet state), and the atomized mixed fluid can be ejected from the two-fluid atomizing nozzle 10 driven by the high-flow rate first fluid. Therefore, different jet structures can be achieved by designing the outlet structure of the two-fluid atomizing nozzle.

[0062] In the embodiment of the present invention, the function of the two-fluid atomizing nozzle is to quickly deliver the aromatherapy essential oil droplets to the appropriate area through the mixed fluid. The droplets evaporate rapidly as the jet impacts the surrounding air, and the aromatherapy essential oil macromolecules in the droplets diffuse from the droplets, thereby rapidly increasing the concentration of the aromatherapy macromolecules in a specific area.

[0063] The air pressure boosting module is used to provide the two-fluid atomizing nozzle with a preset pressure of airflow. It should be noted that the normal operation of the two-fluid atomizing nozzle requires a high-speed airflow, which can also be understood as the instantaneous release of high-pressure airflow according to actual applications.

[0064] Accordingly, there are two main implementation methods to obtain high-speed airflow: on the one hand, directly using electric components to provide high-speed airflow, and on the other hand, compressing the gas before releasing it.

[0065] Since the two-fluid atomizing nozzle has a high requirement for the air flow pressure (the air flow with lower pressure cannot be introduced into the first guide hole), and is limited by noise and volume, the implementation principle of the air pressure boosting module used in the embodiment of the present invention is to compress the gas first and then release it.

[0066] Specifically, the implementation principle of the air pressure boosting module in the embodiment of the present invention is similar to that of an air compressor. The working principle of an air compressor is that an electric device presses gas into a cylinder through an electric element. As the compressed gas increases, the air pressure in the cylinder increases accordingly. However, the conventional air compressor structure cannot be used well in the embodiment of the present invention: on the one hand, because the gas release process and the gas compression process of a conventional air compressor are at different speeds and are not synchronized, this means that a conventional air compressor cannot work in a smaller constant pressure range; on the other hand, because the gas release process and the gas compression process of a conventional air compressor are at different speeds and are not synchronized, in order to increase the speed of the gas compression process, the scale of the electric element has to be increased, which results in more volume and noise.

[0067] Therefore, the present invention provides an air pressure boosting module structure for implementation reference according to actual usage requirements. Figure 4 This is a schematic diagram of the structure of an air pressure boosting module according to an embodiment of the present invention. Specifically, the air pressure boosting module according to the embodiment of the present invention includes a plurality of pump units and a plurality of cylinder units, each of which includes a pump body and corresponding supporting components, and the pump body is used to pressurize gas into the cylinder; the cylinder unit includes an inlet switch, a cylinder, an outlet switch, an air pressure sensor and related supporting components, specifically, the inlet switch is connected to the gas input port of the cylinder, the outlet switch is connected to the gas output port of the cylinder, the air pressure sensor is used to monitor the air pressure inside the cylinder, and control the opening and closing of the inlet switch and the outlet switch according to the air pressure inside the cylinder, and the air pressure opening and closing thresholds of the inlet switch and the outlet switch can be controlled by a central control module to be described later.

[0068] Specifically, the specific number of pump units and cylinder units can be set according to actual needs. In order to achieve the design effect, the number of cylinder units needs to be greater than or equal to two groups. In the embodiment of the present invention, the combination of two groups of pump units and three groups of cylinder units is used as an example for explanation, and in order to distinguish different body units and cylinder units, the first, second, and third prefixes are added to the relevant structures for explanation.

[0069] Reference Figure 4Before the aromatherapy device is officially working, the first pump body and the second pump body jointly increase the pressure of the first cylinder body, the second cylinder body and the third cylinder body. At this time, the outlet switch of each cylinder unit remains closed, and the inlet switch of each cylinder unit remains open; after the aromatherapy machine is started, the central control module will send out the pressure interval instruction corresponding to the working pressure interval [a, b] to each pressure sensor in sequence. According to the issued pressure interval instruction, the cylinder unit starts to switch to the preparation state. After the first pressure sensor receives the working pressure interval [a, b], it determines whether the current pressure of the first cylinder is within the range. If the current air pressure of the first cylinder is not within the working air pressure range, the first gate switch is first closed, and then the outlet switch is opened for pressure relief. At this time, the first cylinder unit is in the pressure relief condition. When the pressure relief is completed and the real-time air pressure of the first cylinder is within the working air pressure range, the first cylinder unit starts to switch to the working condition, keeping the first gate switch closed and the outlet switch open until the air pressure value obtained by the first air pressure sensor is less than the lower limit of the working air pressure range [a, b]. At this time, the first cylinder unit starts to switch to the pressure maintaining condition, the first outlet switch is closed, and the first inlet switch is opened. Specifically, the three cylinder units can be switched to the preparation condition and the pressure relief condition at the same time. After the preparation condition and the pressure relief condition are completed, the three cylinder units are switched to the working condition in sequence, that is, after the first cylinder unit is switched from the working condition to the pressure-maintaining condition, the second cylinder unit starts to switch to the working condition again. After the second cylinder unit is switched from the working condition to the pressure-maintaining condition, the third cylinder unit starts to switch to the working condition again. After the third cylinder unit is switched from the working condition to the pressure-maintaining condition, the first cylinder unit needs to switch from the pressure-maintaining condition to the working condition, and this is carried out in sequence until the central control module issues a new instruction. Specifically, during the entire working process of the cylinder unit, each pump unit remains in a working state. Generally, based on the design purpose, that is, in order to reduce the need for noise, multiple pumps are When the body unit is in working state, it cannot fully replenish the pressure of each cylinder body. Therefore, in actual operation, when the first cylinder body is in working condition for the first time, the change value of its internal pressure is theoretically from b to a, and when the first cylinder body is in working condition for the second time, the change value of its internal pressure may only be from 70%b to a, and when the first cylinder body is in working condition for the second time, the change value of its internal pressure may only be from 50%b to a. However, in the actual application of the embodiment of the present invention, since what is needed is short-term relatively accurate pressure airflow control, therefore, through the circulation cooperation of multiple cylinder body units, in a short time, it is possible to ensure that the airflow output meets the air pressure requirements, and due to the use of multiple pump bodies, better control can be achieved in terms of noise.

[0070] The essential oil module is used to provide a preset flow of aromatherapy essential oil to the two-fluid atomizing nozzle. Specifically, the flow rate of the aromatherapy essential oil affects the number of droplets in the mixed airflow finally sprayed by the two-fluid atomizing nozzle, and indirectly affects the concentration of aromatherapy macromolecules in the action area of ​​the two-fluid atomizing nozzle. The specific structure of the essential oil module can adopt a combination structure of a frequency conversion pump, a flow meter and an essential oil tank. The essential oil tank is used to store essential oils. The coordinated use of the frequency conversion pump and the flow meter can accurately control the flow rate of the aromatherapy essential oil output to the two-fluid atomizing nozzle. Specifically, the frequency conversion pump and the flow meter can be respectively connected to the central control module for control.

[0071] The nozzle attitude adjustment module is used to adjust the attitude of the two-fluid atomizing nozzle to adjust the output direction of the nozzle. Specifically, regarding the implementation structure of the nozzle attitude adjustment module, a posture adjustment structure directly targeting the two-fluid atomizing nozzle can be adopted, or the two-fluid atomizing nozzle can be fixed on the aromatherapy machine body to control the attitude of the two-fluid atomizing nozzle by directly adjusting the attitude of the aromatherapy machine body.

[0072] The central control module is used to receive the relative position information and the basic concentration information of the aromatherapy essential oil, and control the nozzle posture adjustment module to adjust the output direction of the two-fluid atomizing nozzle according to the relative direction information, adjust the preset pressure of the air pressure boosting module according to the relative distance information so that the two-fluid atomizing nozzle sprays the atomized aromatherapy essential oil and quickly delivers it to the relative position where the target object is located, and adjust the preset flow rate of the essential oil module according to the basic concentration information of the aromatherapy essential oil so that the concentration of the aromatherapy essential oil in the area where the target object is located is always within a preset range that makes the target user feel comfortable.

[0073] The concentration of the aromatherapy essential oil in the area where the target object is located can be determined by converting the basic concentration information of the aromatherapy essential oil obtained by the concentration sensing module and the relative distance information of the target object through a predetermined conversion coefficient, and the conversion coefficient is between 0 and 1.

[0074] The conversion coefficient can be determined by multiple measurements in advance or by empirical values. The concentration of the aromatherapy essential oil in the environment of the area where the target object is located is roughly inversely proportional to the base concentration of the aromatherapy essential oil with the relative distance between the target object and the aromatherapy machine. When the relative distance between the target object and the aromatherapy machine is large, the concentration of the aromatherapy essential oil in the target object environment is relatively low, and the conversion coefficient is small at this time, that is, the base concentration of the aromatherapy essential oil at this time is multiplied by a smaller conversion coefficient to estimate the concentration of the aromatherapy essential oil in the environment of the area where the target object is located. On the contrary, if the target object is close to the aromatherapy machine, that is, the relative distance is small, the concentration of the aromatherapy essential oil in the target object environment is relatively close, and the conversion coefficient is large or even close to 1.

[0075] Combined with the above description of the composition structure of the aromatherapy machine, the most basic operating principle of the aromatherapy machine in the embodiment of the present invention is:

[0076] 1. The central control module is started after receiving a user's demand signal for the aromatherapy machine through a preset path. The central control module obtains the relative position information of the target object relative to the aromatherapy machine through the position sensing module. The relative position information includes the relative direction information and relative distance information of the target object relative to the aromatherapy machine.

[0077] 2. Synchronously, the central control module obtains the basic concentration information of the aromatherapy essential oil in the environment where the aromatherapy machine is located through the concentration sensing module, and uses the relative direction information, relative distance information and the basic concentration information of the aromatherapy essential oil; the central control module finds the corresponding control parameters through a preset program (the control parameters include a first parameter for controlling the air pressure boosting module, a second parameter for controlling the essential oil module and a third parameter for controlling the nozzle posture adjustment module); the central control module starts to send the first parameter to the air pressure boosting module, the second parameter to the essential oil module, and the third parameter to the nozzle posture adjustment module; after receiving the third parameter, the nozzle posture adjustment module adjusts the posture of the two-fluid atomizing nozzle according to the third parameter.

[0078] 3. The air pressure boosting module works according to the second parameter and outputs the airflow of preset pressure to the two-fluid atomizing nozzle; after receiving the second parameter, the essential oil module provides the two-fluid atomizing nozzle with a preset flow of aromatherapy essential oil; the two-fluid atomizing nozzle is a structural component, and when the air pressure boosting module and the essential oil module work together, the output port of the two-fluid atomizing nozzle outputs a mixed airflow (jet), and the final arrival area of ​​the mixed airflow is the area where the target user is located.

[0079] After the mixed airflow reaches the target user's area, the droplets in the mixed airflow are also broken and volatilized by the ambient air, and the aromatherapy macromolecules are fully and freely diffused, thereby rapidly increasing the concentration of aromatherapy macromolecules in the target user's area, and the user can enjoy the effect of the aromatherapy machine in time.

[0080] While performing the above operations, the aromatherapy machine senses the position of the target object (or target user) in real time through the position sensing module, and then dynamically adjusts the posture of the two-fluid atomizing nozzle so that the two-fluid atomizing nozzle can spray airflow toward the target user. At the same time, the preset pressure of the air pressure boosting module is dynamically adjusted according to the relative distance information so that the two-fluid atomizing nozzle sprays the atomized aromatherapy essential oil quickly to the relative position of the target object. Then, the preset flow rate of the essential oil module is dynamically adjusted according to the basic concentration information of the aromatherapy essential oil so that the basic concentration of the aromatherapy essential oil is always within the preset range. Therefore, the aromatherapy machine can track the target object in real time and accurately spray atomized aromatherapy essential oil droplets towards the environment where the target object is located. The waiting time is short, so that the target object can quickly feel the pleasure brought by the aromatherapy essential oil; and, by dynamically and automatically adjusting the preset flow rate of the essential oil module, the concentration of the aromatherapy essential oil in the environment can always be maintained within a preset range that makes the user feel comfortable, which can avoid the potential adverse effects of excessively high concentrations of the aromatherapy essential oil on the user, and can also avoid the adverse effects of poor user experience when the concentration of the aromatherapy essential oil is too low, thereby dynamically adjusting the aromatherapy concentration to enable the target user to obtain better comfort.

[0081] Among them, for the two-fluid atomizing nozzle, after the specific selection of the two-fluid atomizing nozzle is completed, the two-fluid atomizing nozzle can be basically tested to obtain the actual control parameters of the air pressure boosting module and the essential oil module.

[0082] Specifically, in the application of the embodiment of the present invention, the area that can be radiated by the jet generated by the two-fluid atomizing nozzle is mainly affected by the high-pressure airflow generated by the air pressure boosting module. The change in the flow rate of the aromatherapy essential oil output by the essential oil module has a very small influence on the area that can be radiated by the jet. The change in the flow rate of the aromatherapy essential oil of the essential oil module mainly has a greater influence on the concentration of aromatherapy macromolecules in the area that can be radiated by the jet.

[0083] The pressure of the high-flow airflow generated by the air pressure boost module not only affects the atomization effect of the aromatherapy essential oil in the two-fluid atomizer nozzle, but also determines the distance of the area that the aromatherapy droplets can reach. Specifically, the greater the pressure of the airflow, the greater its flow rate, the greater the flow rate difference between the two-fluid atomizer nozzle and the low-flow aromatherapy essential oil droplets, and the better the mixed atomization effect of the two; at the same time, the greater airflow pressure determines that the atomized aromatherapy essential oil can also be sprayed out from the two-fluid atomizer nozzle at a greater flow rate, so that the atomized aromatherapy essential oil can also be quickly delivered to a farther area, so that the atomized aromatherapy essential oil can quickly reach the target user area, thereby reducing waiting time and improving the user experience of the target user.

[0084] The aromatherapy essential oil flow rate output by the essential oil module mainly determines the density / concentration of the aromatherapy essential oil droplets in the high-pressure airflow. Therefore, by adjusting the aromatherapy essential oil flow rate output by the essential oil module, the aromatherapy essential oil concentration in the area where the target user is located can be adjusted accordingly, so that the aromatherapy essential oil concentration in the area environment is kept within a range that the user feels comfortable.

[0085] When testing the two-fluid atomizing nozzle, the jet radiation range of the two-fluid atomizing nozzle is mainly determined by adjusting the output pressure of the air pressure boosting module. Specifically, since the gas itself is not directly observable, and considering that the aromatherapy essential oil will have a small impact on the jet radiation area, during the test, the two-fluid atomizing nozzle can input a colored pigment as a liquid fluid, and observe the jet radiation range of the two-fluid atomizing nozzle under different gas pressures by direct observation. In addition, a color indicator can be used as a liquid fluid to input into the two-fluid atomizing nozzle, and the jet radiation range of the two-fluid atomizing nozzle under different gas pressures can be observed by arranging a test paper probe corresponding to the color indicator in space. Therefore, when the aromatherapy machine is working, the distance of the target user sensed by the position sensing module is associated with the corresponding data in the test structure, thereby generating the required first parameter.

[0086] As for the second parameter, the second parameter is mainly used for the essential oil module to adjust the supply speed of the aromatherapy essential oil to the two-fluid atomizer nozzle. The supply speed of the aromatherapy essential oil mainly affects the concentration increase speed of the aromatherapy macromolecules in the jet target area of ​​the two-fluid atomizer nozzle. In actual implementation, the basic concentration information of the aromatherapy essential oil obtained by the concentration sensing module can be understood as the basic aromatherapy macromolecule concentration information in the space. By comparing with the most suitable aromatherapy macromolecule concentration in the space, the number of aromatherapy macromolecules that need to be supplemented in the target user's area can be obtained, which is also the generation principle of the second parameter.

[0087] For the third parameter, the third parameter is mainly generated according to the posture control method of the two-fluid atomizing nozzle. According to the different actual implementation structures of the nozzle posture adjustment module, the third parameter also needs to be changed accordingly so that the two-fluid atomizing nozzle can point to the direction of the target user relative to the aromatherapy machine obtained by the position sensing module.

[0088] Figure 5 Flow chart of the dynamic adjustment control method of the aromatherapy machine according to the embodiment of the present invention. Accordingly, for the aromatherapy machine according to the embodiment of the present invention, the present invention provides a dynamic adjustment control method of the aromatherapy machine, including steps S101-S105.

[0089] S101: The central control module obtains the relative position information of the target object relative to the aromatherapy machine in real time based on the position sensing module, and obtains the basic concentration information of the aromatherapy essential oil in the environment where the aromatherapy machine is located based on the concentration sensing module.

[0090] Specifically, the relative position information includes relative direction information and relative distance information of the target object relative to the aromatherapy machine. In an embodiment of the present invention, the relative direction information of the aromatherapy machine is obtained based on a human presence sensor, and the relative direction information is obtained based on a recording device matrix.

[0091] S102: The central control module adjusts the output direction of the two-fluid atomizing nozzle through the nozzle posture adjustment module based on the relative position information.

[0092] Specifically, since the aromatherapy machine is generally in a fixed position, the central control module mainly controls the nozzle attitude adjustment module based on the relative direction information in the relative position information; the central control module generates the relevant third parameter according to the relative direction information and the control logic of the nozzle attitude adjustment module, and the central control module sends the third parameter to the nozzle attitude adjustment module. After receiving the third parameter, the nozzle attitude adjustment module performs a corresponding action to adjust the jet output direction of the two-fluid atomizing nozzle to point to the direction of the target object.

[0093] S103: The central control module controls the air flow pressure output to the two-fluid atomizing nozzle by adjusting the air pressure boosting module based on the relative position information.

[0094] Specifically, the airflow pressure of the air pressure boosting module mainly affects the maximum radiation radius of the output jet of the two-fluid atomizing nozzle. Therefore, the airflow pressure finally output by the air pressure boosting module is mainly based on the relative distance information in the relative position information. Through the calibrated corresponding relationship data of the relative position information and the airflow pressure, the central control module generates a first parameter according to the relative distance information and sends the first parameter to the air pressure boosting module. The air pressure boosting module adjusts the airflow pressure output to the two-fluid atomizing nozzle according to the first parameter, so that the output jet of the two-fluid atomizing nozzle can radiate to the area where the target object is located.

[0095] S104: The central control module controls the flow rate of the aromatherapy essential oil output to the two-fluid atomizing nozzle by adjusting the essential oil module based on the basic concentration information of the aromatherapy essential oil.

[0096] Specifically, the essential oil module mainly affects the increasing speed of the aromatherapy macromolecule concentration in the radiation area of ​​the output jet of the two-fluid atomizing nozzle. Therefore, the central control module calculates the difference information based on the basic concentration information of the aromatherapy essential oil and the most suitable aromatherapy essential oil concentration, and through the calibrated correspondence data between the difference information and the aromatherapy essential oil flow rate, the central control module generates a second parameter based on the difference information and sends the second parameter to the essential oil module.

[0097] The essential oil module adjusts the flow rate of the aromatherapy essential oil output to the two-fluid atomizing nozzle according to the second parameter, thereby changing the aromatherapy essential oil content in the output jet of the two-fluid atomizing nozzle and changing the total amount of aromatherapy essential oil that ultimately reaches the area where the target object is located. The total amount of aromatherapy essential oil affects the concentration of aromatherapy macromolecules at that location.

[0098] S105: The two-fluid atomizing nozzle receives the airflow provided by the air pressure boosting module and the aromatherapy essential oil provided by the essential oil module, and emits a mixed jet of the airflow and the aromatherapy essential oil to the spatial position where the target object is located.

[0099] In summary, the embodiment of the present invention provides an aromatherapy machine and a dynamic adjustment control method of the aromatherapy machine, which improves the implementation structure and implementation method of the aromatherapy machine in accordance with the indoor use scene, and can dynamically adjust and control the concentration of the aromatherapy macromolecules in the space where the target object is located, reduce the waiting time of the target object, and improve the user's comfort. Specifically, in terms of structure, the position of the target object is obtained by adding a position sensing module, and the nozzle attitude adjustment module is used to adjust the direction of the nozzle based on this, and the two-fluid atomizing nozzle is used as the atomizing element to ensure the radiation distance of the aromatherapy device, so that the directional and fixed-distance injection of the aromatherapy essential oil can be achieved; the two-fluid atomizing nozzle is used as the atomizing element for the first time on the aromatherapy device in the home environment, and the air pressure boosting module is improved according to the limitations of the home environment, so as to ensure that the airflow that meets the pressure requirements is provided under low noise conditions, and has good practicality; in terms of method, the combination of multiple modules enables the aromatherapy machine to control the concentration of the aromatherapy macromolecules according to the position of the target object, and ensures the comfort of the target object using the aromatherapy machine.
