Description

Technical Field

[0001] This application relates to the field of terminal equipment, and more particularly to a fragrance dispersing device and a fragrance dispersing control method. Background Technology

[0002] With advancements in scientific extraction techniques, the application of fragrances has become more widespread, as fragrances can relax both the body and mind. Fragrance-emitting devices can be located in cars, indoors, or any portable device, such as wearable devices, mobile phones, home robots, home aromatherapy lamps, or standalone devices integrated into car air vents.

[0003] In existing implementations, fragrance diffusers achieve fragrance diffusion by heating the fragrance substance using a heating device. However, the fragrance substance (such as perfume) is a consumable material, and the existing fragrance diffusers consume the fragrance substance too quickly, requiring users to replace it frequently. Summary of the Invention

[0004] This application provides a fragrance emission device and a fragrance emission control method, which makes fragrance emission control more precise and reduces the consumption of fragrance substances.

[0005] In a first aspect, this application provides a fragrance dispersing device, the device comprising: a first array assembly, a second array assembly, and a housing; wherein the first array assembly and the second array assembly are fixed inside the housing; the first array assembly includes a plurality of slots for containing fragrance dispersing substances; the second array includes a plurality of heating points, each heating point facing a corresponding slot among the plurality of slots, and each heating point is used to heat the corresponding slot.

[0006] In this embodiment, the fragrance-dispersing substance is arranged in an array of slots, and a corresponding heating point is set for each slot. The fragrance can be dispersed by controlling the heating of the slots through the heating points. Compared with the existing whole-piece control, the array arrangement and array-based fragrance dispersion control in this embodiment make the fragrance dispersion control more precise and reduce the consumption of fragrance-dispersing substance.

[0007] In one possible implementation, the first array assembly comprises only one integrally formed plate having multiple slots; or, the first array assembly comprises multiple integrally formed plates, each having at least one slot.

[0008] In one possible implementation, there are gaps between different plates in multiple integrally molded plates.

[0009] This application embodiment disperses fragrance by heating the fragrance material. If the tanks for different types of fragrance materials are too close together, it will cause mutual interference during heating (for example, when heating tank A, heat will also be transferred to tank B). If the heating point only wants to heat type A fragrance material, and the tanks for type A and type B fragrance materials are too close together, it will cause heat to be transferred to the tanks for type B fragrance material while heating the tank for type A fragrance material, making it impossible to accurately control the fragrance type. In this application embodiment, the different plates are separated so that when heating the tanks for different types of fragrance materials, the fragrance dispersion of different scent areas will not interfere with each other.

[0010] Optionally, the first array components can be distributed on a 2D plane, such as, but not limited to, a circular or irregularly shaped plane. Optionally, the first array components can be distributed on a 3D spatial surface, such as, but not limited to, a tetrahedron or an octahedron.

[0011] In one possible implementation, a vent is provided on the side of the housing facing the first array assembly.

[0012] In one possible implementation, the device further includes a heating controller; the heating controller is used to control multiple heating points to heat the corresponding tank.

[0013] In one possible implementation, the heating controller is specifically used to: obtain the fragrance concentration; and, based on the fragrance concentration, control N heating points out of a plurality of heating points to heat the corresponding tank, where N is positively correlated with the fragrance concentration and N is an integer.

[0014] In one possible implementation, the heating controller can control N heating points out of a plurality of heating points to heat the corresponding tanks based on the fragrance concentration, where N is positively correlated with the fragrance concentration. That is, when the fragrance concentration is high, more tanks need to be heated, thereby increasing the amount of fragrance released per unit time and thus increasing the fragrance concentration more quickly.

[0015] In one possible implementation, the heating controller is also used for:

[0016] Based on the priority coefficient of each heating point among multiple heating points, N heating points are selected from the multiple heating points. The priority coefficient of each of the N heating points is higher than the priority coefficient of other heating points among the multiple heating points excluding the N heating points. The priority coefficient is inversely proportional to the number of slots adjacent to the heating points and equipped with fragrance-dispersing substances.

[0017] When there are many adjacent heating points with a large number of slots containing fragrance substances, the heat will be transferred to other heating points around the heating point due to heat diffusion during heating, thereby reducing the accuracy of fragrance concentration control. In this embodiment, a slot with a smaller number of adjacent slots containing fragrance substances can be selected for heating, thereby improving the accuracy of fragrance concentration control.

[0018] In one possible implementation, obtaining the fragrance concentration includes: obtaining the fragrance concentration input by the user; or, obtaining the fragrance concentration in the air surrounding the fragrance dispersing device, and determining the fragrance concentration based on the fragrance concentration, wherein the fragrance concentration is negatively correlated with the fragrance concentration.

[0028] The heating controller selects N heating points from the multiple heating points based on the priority coefficient of each heating point. The priority coefficient of each of the N heating points is higher than the priority coefficient of other heating points besides the N heating points.

[0065] With advancements in scientific extraction techniques, the application of fragrances has become more widespread, as fragrances can relax both the body and mind. Fragrance-emitting devices can be located in cars, indoors, or any portable device, such as wearable devices, mobile phones, home robots, home aromatherapy lamps, or standalone devices integrated into car air vents.

[0066] In existing implementations, fragrance diffusers achieve fragrance diffusion by heating the fragrance substance using a heating device. However, the fragrance substance (such as perfume) is a consumable material, and existing fragrance diffusers consume the substance too quickly, requiring frequent replacement by the user. This application provides a fragrance diffusion device that enables precise control of fragrance diffusion and reduces the consumption rate of the fragrance substance.

[0067] The application architecture of this application embodiment will be introduced next:

[0068] The fragrance-emitting device in this embodiment can be applied to mobile terminal devices such as mobile phones, wearable devices, Internet of Things (IoT) ecosystem devices, and robots. Optionally, the device can communicate with the end-side device via hardware circuitry to achieve on-demand fragrance emission. Furthermore, the fragrance-emitting device can be applied to jewelry such as necklaces and personal accessories.

[0069] Reference Figure 1 , Figure 1 This is a schematic diagram of a system architecture according to an embodiment of this application. Figure 1 The fragrance emitting device 100 is shown installed on a vehicle-mounted device. Figure 1 The fragrance emitting device 100 is shown to be installed near the steering wheel and gear shift area. In addition, the fragrance emitting device 100 can also be installed in other areas of the cockpit, which is not limited here.

[0070] Optionally, the fragrance emitting device 100 can communicate with in-vehicle equipment in the driver's cabin, allowing the user to control the fragrance emission of the fragrance emitting device 100 via the in-vehicle equipment. Alternatively, the user can also operate the fragrance emitting device 100 directly to control its fragrance emission.

[0071] Reference Figure 2 The fragrance emitting device 100 can be installed on the necklace.

[0072] The following describes a fragrance dispersing device provided in an embodiment of this application, referring to... Figure 3 , Figure 3 A schematic diagram of the structure of the fragrance emitting device 100 provided in the embodiments of this application is shown below. Figure 3 As shown, the device 100 includes: a first array group 101, a second array assembly 102, and a housing; wherein,

[0073] The first array component 101 and the second array component 102 can be fixed inside the housing.

[0074] In one possible implementation, the first array component 101 and the second array component 102 are arranged in parallel within the housing.

[0075] In one possible implementation, the first array component 101 includes a plurality of slots for containing fragrance substances.

[0076] Among them, the fragrance substance can also be called the aromatic substance. For example, the fragrance substance can be liquid perfume, solid fragrance, etc., and there is no limitation here.

[0077] The groove can be a region on the first array component 101 used to contain the fragrance substance, such as a recessed region or a region of other shapes, which is not limited in this application.

[0078] Multiple slots for containing fragrance substances can be arranged in an array on the first array component 101, with intervals between different slots.

[0079] Optionally, the size of each slot in the first array component can be different, and the slots can be arranged uniformly, in a row-column pattern, or randomly. This application does not limit this.

[0080] In one possible implementation, the first array assembly 101 may consist of only a single integral plate having a plurality of slots.

[0081] Optionally, the plate can be prepared using PDMS material through a demolding process, or it can be prepared by coating a colloid onto a substrate and then etching it.

[0082] Optionally, the aforementioned one-piece molded plate can be provided with multiple regions, each region having a groove for holding a fragrance substance of one scent, and different regions having grooves for holding fragrance substances of different scents.

[0083] In one possible implementation, the first array assembly 101 includes a plurality of integrally formed plates, each plate having at least one of the slots (e.g., see reference to...). Figure 4 (As shown).

[0084] Optionally, a slot in one plate is used to hold a fragrance substance of one scent, and slots in different plates are used to hold fragrance substances of different scents.

[0085] In one possible implementation, there are gaps between different plates in the plurality of integrally formed plates.

[0086] Optionally, the size of each heating point in the second array component can be different, and the arrangement of the heating points can be uniform, row-column, or random. This application does not limit this.

[0087] The different plates mentioned above can be referred to as different fragrance-dispersing material zones. Optionally, the different fragrance-dispersing material zones and their corresponding heating arrays can be spaced apart, with fragrance-dispersing airflow outlets above each zone. Alternatively, the different fragrance-dispersing material zones can be separated by an outer shell, with fragrance-dispersing airflow outlets above each zone, while the heating arrays remain connected, and the droplets and heating cores correspond one-to-one in space.

[0088] This application embodiment disperses fragrance by heating the fragrance material. If the tanks for different types of fragrance materials are too close together, it will cause mutual interference during heating (for example, when heating tank A, heat will also be transferred to tank B). If the heating point only wants to heat type A fragrance material, and the tanks for type A and type B fragrance materials are too close together, it will cause heat to be transferred to the tanks for type B fragrance material while heating the tank for type A fragrance material, making it impossible to accurately control the fragrance type. In this application embodiment, the different plates are separated so that when heating the tanks for different types of fragrance materials, the fragrance dispersion of different scent areas will not interfere with each other.

[0089] Optionally, the first array component 101 can be distributed on a 2D plane, such as, but not limited to, a circular or irregularly shaped plane. Optionally, the first array component 101 can be distributed on a 3D spatial surface, such as, but not limited to, a tetrahedron or an octahedron.

[0090] In one possible implementation, the second array of the fragrance emitting device 100 may include a plurality of heating points, each heating point facing a corresponding slot in the plurality of slots, each heating point being used to heat the corresponding slot.

[0091] Each slot in the first array component 101 can be aligned vertically with a heating point in the second array component 102, forming a physical structure in which slots and heating points correspond one-to-one (or one-to-many, many-to-one) in space. For example, one heating point corresponds to two slots, or two heating points correspond to one slot, or one heating point corresponds to one slot. This application embodiment is not limited to this.

[0092] In one possible implementation, the second array component 102 can be a heating electrode array, for example, it can be a high-resistivity metal material such as copper or silver.

[0093] In one possible implementation, a vent may be provided on the side of the housing facing the first array assembly 101. Optionally, the vent may guide the fragrance to diffuse.

[0094] In one possible implementation, an encapsulation film may also be provided on the first array component 101, wherein the encapsulation film is breathable but waterproof, and is placed on the surface of the first array component 101 to prevent the loss of fragrance substances due to the movement, flipping or falling of the fragrance dispersing device 100.

[0095] In one possible implementation, the encapsulation film can be one or more layers of breathable but waterproof film, such as a single or multiple layers of Teflon film.

[0096] Optionally, the outer surface of the fragrance emitting device 100 may also be covered with heat-insulating materials, such as heat-insulating film or air gap.

[0097] In one possible implementation, the fragrance emitting device 100 further includes a heating controller 103; the heating controller 103 is used to control the plurality of heating points to heat the corresponding slots.

[0098] In one possible implementation, the fragrance emitting device 100 also includes an ambient temperature module that senses the ambient temperature and transmits the ambient temperature value to the heating controller 103.

[0099] The heating controller 103 can adjust the heating strategy according to the ambient temperature, trigger the ambient temperature module to sense the temperature, and trigger the heating point to heat the perfume droplets; and select the heating point for heating according to the relative position relationship and fragrance relationship between the heating points.

[0100] The heating controller 103 can control the fragrance type, fragrance concentration, or fragrance dissipation time, which will be explained in detail below:

[0101] 1. Regarding the control of fragrance type:

[0102] In one possible implementation, the user can operate the fragrance dispersing device 100 through a terminal device or directly to generate a fragrance dispersing command. The fragrance dispersing command may include the type of perfume for this fragrance dispersal (optionally, a perfume ID may be used to represent the fragrance type).

[0103] Optionally, it can be triggered by the user through the application (APP) interface; or it can be triggered based on the monitoring results of the fragrance concentration in the air by gas sensors built in or distributed in other spaces.

[0104] 2. Control of aroma concentration:

[0105] In one possible implementation, the heating controller 103 is specifically used to: obtain the fragrance concentration; and control N heating points among the plurality of heating points to heat the corresponding tank according to the fragrance concentration, wherein N is positively correlated with the fragrance concentration and N is an integer.

[0106] Among them, the fragrance concentration can be understood as the target fragrance concentration for this fragrance release, which is the amount of fragrance that needs to be emitted per unit time.

[0107] In one possible implementation, obtaining the fragrance concentration may specifically include: obtaining the fragrance concentration input by the user. Optionally, this can be triggered by the user through the application (APP) interface. For example, the fragrance concentration can be represented by a light fragrance, a strong fragrance, or by the number of heating points that are simultaneously activated.

[0108] In one possible implementation, obtaining the fragrance concentration may specifically include: obtaining the fragrance concentration in the air surrounding the fragrance emitting device 100, determining the fragrance concentration based on the fragrance concentration, wherein the fragrance concentration is negatively correlated with the fragrance concentration.

[0109] The concentration of fragrance in the air can be monitored by a gas sensor built into the fragrance emitting device 100 or by gas sensors distributed in other spaces, and the fragrance concentration can be determined based on the monitoring results. For example, if the fragrance concentration in the air around the fragrance emitting device 100 is low, the fragrance concentration is high.

[0110] In one possible implementation, the heating controller 103 can control N heating points out of the plurality of heating points to heat the corresponding tanks according to the fragrance concentration, where N is positively correlated with the fragrance concentration. That is, when the fragrance concentration is high, more tanks need to be heated, thereby increasing the amount of fragrance released per unit time and thus increasing the fragrance concentration more quickly.

[0111] Next, we will explain how to select the N tanks that need to be heated from a pool of multiple tanks.

[0112] In one possible implementation, the heating controller 103 is further configured to: select N heating points from the plurality of heating points according to the priority coefficient of each heating point among the plurality of heating points, wherein the priority coefficient of each heating point among the N heating points is higher than the priority coefficient of other heating points among the plurality of heating points besides the N heating points, and the priority coefficient is inversely proportional to the number of slots adjacent to the heating points and provided with fragrance-dispersing substances.

[0113] When there are many adjacent heating points with a large number of slots containing fragrance substances, the heat will be transferred to other heating points around the heating point due to heat diffusion during heating, thereby reducing the accuracy of fragrance concentration control. In this embodiment, a slot with a smaller number of adjacent slots containing fragrance substances can be selected for heating, thereby improving the accuracy of fragrance concentration control.

[0114] For example, within the area of ​​a heating point, one or more optimal heating points can be selected for heating based on the remaining amount of perfume, allowing the fragrance to diffuse. When the area of ​​the heating array is small, considering that the heating points are prone to heat conduction during heating, causing the surrounding perfume droplets to evaporate more quickly and reducing the fragrance diffusion accuracy, it is necessary to optimize the heating point selection strategy. The heating point selection algorithm mainly considers the number of perfume droplets with the same fragrance around the heating electrode and the number of perfume droplets with different fragrances.

[0115] For example, based on the perfume array reserve table, we can look up the number of neighbors of droplets with the same fragrance around the heating point as N1, and the number of neighbors of droplets with different fragrances as N2. Droplets with a reserve of 0 do not belong to the two categories described above.

[0116] Next, the priority coefficient for each heating point is calculated (for example, S = 9 - N1 - N2 * 2). The reason for setting the coefficient of N2 to be relatively large is that if adjacent slots contain different types of fragrances, it will have a greater impact on the precision control of fragrance emission (in addition to the influence of concentration, there is also the influence of fragrance type). The heating points are sorted according to their scores, and the heating points with higher rankings are selected for heating first. When multiple heating points have the same priority score, one or more can be randomly selected for heating.

[0117] For example, you can refer to Figure 5 , Figure 5 This diagram illustrates the calculation of priority coefficients, where darker colors indicate higher priority coefficients. (The text then repeats itself, seemingly from a different source.) Figure 5 Start by selecting the darkest heating point, and then randomly select from heating points of the same color.

[0118] 3. Regarding the control of fragrance dissipation time:

[0119] In one possible implementation, the fragrance dispersal time can be either the duration of fragrance dispersal or the time interval between fragrance dispersals.

[0120] In one possible implementation, the heating controller 103 is specifically used to: obtain the fragrance dissipation time; and control the plurality of heating points to heat the corresponding slots according to the fragrance dissipation time.

[0121] Optionally, the fragrance dispersal time can be triggered by the user through the APP interface; or it can be triggered based on the monitoring results of the fragrance concentration in the air by built-in or distributed gas sensors in other spaces.

[0122] The following is a complete flowchart illustrating the process of heating the heating points controlled by the heating controller 103:

[0123] Step 1: Receive the fragrance dispersal instruction, which includes the fragrance type (which can be identified by the fragrance ID), concentration (light or strong fragrance, including the number of heating points that are turned on at the same time), and dispersal time (e.g., dispersal duration or dispersal interval).

[0124] Optionally, the timing for sending the fragrance dispersal command can be triggered by the user through the APP's operation interface, or it can be triggered based on the monitoring results of the fragrance concentration in the air by built-in or distributed gas sensors in other spaces.

[0125] For example, when the fragrance concentration in the air reaches a user-defined threshold or a system-defined threshold, the fragrance dissemination stops; when the fragrance concentration is below the threshold, the fragrance dissemination begins.

[0126] Step 2: According to the fragrance dispersal instruction, determine the amount of liquid (default liquid volume is 0.5uL) required for this fragrance dispersal, the fragrance number, and the corresponding heating point area.

[0127] Step 3: Sensing ambient temperature and adjusting the heating strategy. Assuming the electric heating power remains constant, the heating time required for the heating core to reach the expected temperature (default 50℃) varies under different ambient temperatures. For example, at low temperatures, the heating time needs to be extended; at high temperatures, the heating time can be shortened to reach the expected heating temperature, reducing heating power consumption. The heating strategy includes heating time and heating interval time, and the adjustment method is as follows:

[0128] 1. Based on the analysis of electrothermal and heat dissipation (heat conduction) at the heating electrode, after reaching thermal equilibrium, electric heating continues, but the temperature at the heating electrode no longer rises; that is, the heat flux density reaches its maximum after thermal equilibrium. Therefore, to maximize electrothermal efficiency, heating is stopped after reaching thermal equilibrium. The heating time at this point is t1 = (2*c*m*ΔT) / UI, where U and I are the constant voltage and constant current during heating, respectively, c is the specific heat capacity of the heating core, m is the mass of the heating core, and ΔT is the expected temperature minus the ambient temperature.

[0129] Optionally, c and m can be obtained by looking up a table or by measurement. For example, assume t1 = a*ΔT + b. Under different environmental conditions, measure the time required for the heating core to heat to the expected temperature and calculate the values ​​of a and b. For example, the least squares method can be used for fitting and solving.

[0130] 2. After reaching thermal equilibrium, the temperature at the heating electrode reaches the expected value, and after heating stops, it returns to ambient temperature after a time interval t1. Therefore, the heating interval is t1 plus the user-set fragrance dissipation time interval.

[0131] Optionally, the electric heating power can also be varied. In this case, a temperature sensing module needs to be installed at each heating electrode to adjust the electric heating power. For example, in a low-temperature environment, the electric heating power can be increased in fixed steps (increasing the current, increasing the voltage, or increasing both current and voltage simultaneously). In a high-temperature environment, the electric heating power can be decreased in fixed steps (decreasing the current, decreasing the voltage, or decreasing both current and voltage simultaneously) until the heating electrode reaches the expected temperature, at which point heating can be stopped.

[0132] Step 4: Within the area of ​​the heating point, select one or more optimal heating points based on the remaining space in the perfume array to heat the area, allowing the fragrance to diffuse. When the area of ​​the heating array is small, considering that the heating point is prone to heat conduction during heating, causing the surrounding perfume droplets to evaporate faster and reducing the fragrance diffusion accuracy, it is necessary to optimize the heating point selection strategy. The heating point selection algorithm mainly considers the number of perfume droplets with the same fragrance around the heating electrode and the number of perfume droplets with different fragrances, specifically as follows:

[0133] First, according to the perfume array reserve table, the number of neighbors of the heating point with the same fragrance droplet is N1, and the number of neighbors of the different fragrance droplets is N2. Droplets with a reserve of 0 do not belong to the two categories described above.

[0134] Then, calculate the optimal score S = 9 - N1 - N2 * 2 for each heating point, with a score range of [9, -4]. Based on the heating point scores, prioritize heating the highest-ranked heating point. When multiple heating points have the same optimal score, randomly select one or more for heating.

[0135] Step 5: After heating stops, update the remaining volume of the perfume array based on the heating duration. Assuming the fragrance dissipates at a uniform rate, the fragrance reduction function can be simply modeled as a linear reduction function, and the remaining volume of each perfume droplet is calculated separately. The working principle is as follows: Initially, the volume of a single perfume droplet is g_(i,j) = 0.5uL. After each heating stops, update the remaining volume of the perfume array g_(i,j) = g_(i,j) - t*v.
