Description

Technical Field

[0001] The utility model belongs to the technical field of fragrance, and particularly relates to a fragrance machine. Background Art

[0002] Aroma diffusers are a common appliance that transforms essential oils into tiny particles through atomization technology. These particles are then evenly dispersed into the air, creating a pleasant aroma and enhancing the comfort and ambiance of living or working spaces. Aroma diffusers not only improve air quality but also regulate mood through different aroma formulas, promoting relaxation or refreshing the mind.

[0003] Traditional aroma diffusers still face many challenges when dealing with complex environmental conditions. Specifically, most rely on manual operation to turn them on and off, which can be inconvenient and inefficient in certain situations.

[0004] For example, when an aroma diffuser is placed in an environment lacking natural air flow—that is, in windless or light conditions—the mist formed by the atomized essential oil often struggles to effectively diffuse throughout the space. This limitation leads to a significant problem: the fragrance is overly concentrated and highly concentrated in the area surrounding the diffuser, while areas further away from the diffuser have a weak or even no fragrance at all. This uneven fragrance distribution not only reduces the effectiveness of the aroma diffuser but also significantly impacts the overall user experience, significantly diminishing its practical value.

[0005] Furthermore, because the mist cannot fully diffuse, some of it will condense into essential oils in the air. This condensed oil may clog the diffuser's mist outlet. Once the mist outlet is blocked, the diffuser will not be able to release fragrance properly, thus affecting its ability to continue working. This not only increases maintenance costs for users but may also adversely affect the lifespan of the diffuser.

[0006] Furthermore, existing fragrance diffusers lack sufficient intelligence and automation to respond to changes in wind conditions. If the fragrance diffuser is turned off in calm conditions and then wind picks up, the user must manually restart the machine to resume fragrance diffusion. This frequent on-and-off operation not only increases the user's workload but can also prevent the machine from starting up when needed, further reducing the user experience.

[0007] In summary, with the rapid development of smart home and IoT technologies, users are placing higher demands on the intelligence and automation of fragrance machines. However, existing fragrance machines still have significant shortcomings in intelligent management, environmental perception, and adaptive adjustment, making it difficult to meet users' demands for an efficient, convenient, and intelligent fragrance experience. Utility Model Content

[0008] The primary purpose of the present invention is to solve at least one of the above problems and provide a fragrance machine.

[0009] In order to meet one of the purposes of the present invention, a fragrance machine is provided, including a main body and a wind sensor. The main body includes a shell and an essential oil bottle, an atomizer component and a first control unit arranged in the shell. The atomizer component is used to atomize the liquid contained in the essential oil bottle. The first control unit is electrically connected to the atomizer component and the wind sensor respectively. The wind sensor is arranged outside the main body and is used to detect the wind speed of the external environment and generate an electrical signal. The first control unit is used to control the operation of the atomizer component based on the electrical signal.

[0010] Furthermore, the wind sensor includes a first probe, and the first probe includes a PTC element.

[0011] Furthermore, the wind sensor includes a second probe, and the second probe includes an NTC element.

[0012] In one embodiment, a differential circuit is further provided in the housing, and the differential circuit includes a differential amplifier, wherein two input ends of the differential amplifier respectively receive electrical signals output by the first probe and the second probe, and the output end of the differential amplifier is electrically connected to the first control unit.

[0013] In one embodiment, the wind sensor is further provided with a second control unit and a differential circuit, the differential circuit includes a differential amplifier, the two input ends of the differential amplifier respectively receive the electrical signals output by the first probe and the second probe, and the output end of the differential amplifier is electrically connected to the second control unit.

[0014] In one embodiment, the wind sensor further includes a mounting platform, the first probe and the second probe are arranged on the mounting platform, the PTC element is arranged at the end of the first probe, and the NTC element is arranged at the end of the second probe, and relative to the mounting platform, the height of the first probe is greater than the height of the second probe.

[0015] Furthermore, the distance between the PTC element and the NTC element is ≥10 mm.

[0016] In one embodiment, a separator is further inserted into the first probe, and the separator is disposed between the PTC element of the first probe and the NTC element of the second probe to separate the PTC element from the NTC element.

[0017] In one embodiment, the wind sensor is connected to the first control unit via a cable.

[0018] In one embodiment, a first communication unit is further provided in the shell, the first control unit is electrically connected to the first communication unit, the wind sensor also includes a second communication unit, and wireless signal transmission is realized between the main body and the wind sensor based on the first communication unit and the second communication unit.

[0019] Compared with the prior art, the present invention has many advantages, including but not limited to:

[0020] First, the aroma diffuser of this utility model uses a wind sensor to detect the wind speed of the external environment in real time and controls the operating state of the atomizer component accordingly, achieving intelligent management of the aroma diffuser. In low or no wind conditions, air flow in the indoor space is slow, and the fragrance diffusion effect is poor. In this case, the aroma diffuser can control the atomizer component to stop working based on the wind speed detected by the wind sensor, thereby avoiding unnecessary energy consumption and waste of essential oils. Conversely, when the wind speed is higher, the atomizer component is driven to work, helping the fragrance to diffuse faster and wider, improving the user experience. This intelligent adjustment mechanism not only improves energy efficiency but also extends the service life of the aroma diffuser.

[0021] Secondly, traditional fragrance machines can only be turned on or off manually by the user and cannot be adjusted according to environmental changes. The fragrance machine of the present invention realizes real-time perception and response to the external environment by integrating a wind sensor, thereby enhancing its ability to adapt to different usage environments. Whether it is a home, office or commercial place, the working mode can be flexibly adjusted according to the specific environment to meet diverse needs. With the increasing popularity of smart home and Internet of Things technologies, products with intelligent perception and self-adaptation capabilities are more popular in the market. The fragrance machine of the present invention has achieved intelligent upgrades by introducing wind sensors, which not only improves the technical content and added value of the product, but also enhances its competitiveness in the market.

[0022] Furthermore, the introduction of a wind sensor allows the diffuser to automatically adjust the power of the atomizer based on the ambient wind speed, ensuring optimal fragrance diffusion in all environments. In open spaces with high wind speeds, increasing the atomization volume prevents rapid dilution of the fragrance; whereas in relatively enclosed spaces or those with lower wind speeds, reducing the atomization volume prevents the fragrance from becoming overpowering and causing discomfort. This dynamic adjustment strategy significantly enhances the user's fragrance experience. BRIEF DESCRIPTION OF THE DRAWINGS

It should also be understood that terms such as those defined in common dictionaries should be understood to have meanings consistent with their meanings in the context of the prior art, and will not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0034] The utility model provides a fragrance machine, which is provided with a main body and a wind sensor. The wind sensor is arranged outside the main body. The wind sensor can detect the wind speed (air flow rate) of the external environment, and control the opening and closing of the atomization component of the main body by monitoring the wind speed, that is, control whether the main body discharges mist to the outside, so that the fragrance machine works intelligently.

[0035] In a typical embodiment of the present invention, Figure 1 The fragrance machine 100 includes a main body 110 and a wind sensor 120. The wind sensor 120 and the main body 110 are independently arranged. The wind sensor 120 is arranged outside the main body 110 so that the wind sensor 120 can well detect the wind speed of the external environment.

[0036] Specifically, combined Figure 2 and Figure 3 The main body 110 includes a housing 111, an essential oil bottle 112, an atomizing assembly 113, and a control unit (referred to as a first control unit 114). The essential oil bottle 112, the atomizing assembly 113, and the first control unit 114 are disposed within the housing 111. The essential oil bottle 112 is used to hold liquid, such as essential oil. In this embodiment, the present invention is described using the essential oil bottle 112 as an example of holding essential oil, but this should not be construed as limiting the present invention.

[0037] The atomizing assembly 113 is arranged at the bottle mouth of the essential oil bottle 112, and the atomizing assembly 113 is used to atomize the essential oil in the essential oil bottle 112, so that the essential oil is atomized into tiny particles to form mist. Figure 1 The housing 111 is provided with a mist outlet 115 corresponding to the atomizing assembly 113, so that the mist can be discharged into the external environment through the atomizing assembly 113 and the mist outlet 115 to improve the external air. In this embodiment, it is recommended that the atomizing assembly 113 be a two-fluid atomizing assembly or an ultrasonic atomizing assembly, but this should not be construed as a limitation of the present invention.

[0038] Combine Figure 2 and Figure 3The first control unit 114 is electrically connected to the wind sensor 120 and the atomizer assembly 113. The first control unit 114 controls the atomizer assembly 113 to operate so that the atomizer assembly 113 atomizes the essential oil in the essential oil bottle 112 to form mist. Alternatively, the first control unit 114 controls the atomizer assembly 113 to stop operating so that the main body 110 no longer discharges mist. In this embodiment, it is recommended that the first control unit 114 be a single-chip microcomputer, but this should not be construed as a limitation of the present invention.

[0039] In a typical embodiment of the present utility model, the wind sensor 120 is arranged outside the main body 110, and is used to detect the external wind speed and generate an electrical signal. The wind sensor 120 is connected to the first control unit 114 of the main body 110 by wire or radio, so that the wind sensor 120 outputs an electrical signal to the first control unit 114, and the first control unit 114 controls the atomization component 113 to work or stop working based on the electrical signal.

[0040] Specifically, combined Figure 2 、 Figure 5 and Figure 6 The wind sensor 120 includes a first probe 121, a second probe 122 and a control unit (the control unit is referred to as a second control unit 123), and the second control unit 123 is electrically connected to the first probe 121 and the second probe 122 respectively.

[0041] The first probe 121 includes a PTC (Positive Temperature Coefficient) element. The PTC element 1211 is a positive temperature coefficient thermistor whose resistance increases with increasing temperature. The PTC element 1211 generates heat, raising its own temperature. Air flow (wind speed) removes some of the heat from the PTC element 1211, causing the temperature of the PTC element 1211 to decrease. Because the resistance of the PTC element 1211 increases with temperature, when wind speed is low, the temperature and resistance of the PTC element 1211 are higher. As wind speed increases, heat is removed from the PTC element 1211, causing the temperature and resistance of the PTC element 1211 to decrease. This change in resistance of the PTC element 1211 can be converted into an electrical signal (referred to as the first electrical signal) that represents wind speed. The higher the wind speed, the lower the temperature of the PTC element 1211 and the greater the decrease in its resistance, which affects the magnitude of the first electrical signal and enables accurate wind speed measurement.

[0042] The second probe 122 includes an NTC (Negative Temperature Coefficient) element. The NTC element 1221 is a negative temperature coefficient thermistor whose resistance decreases as temperature increases. The resistance of the NTC element 1221 changes with the ambient temperature. This change in resistance is converted into an electrical signal (referred to as the second electrical signal) that represents the ambient temperature, enabling the NTC element 1221 to monitor the ambient temperature in real time. Furthermore, the NTC element 1221 is separated from the PTC element 1211 to prevent heat from the PTC element 1211 from affecting the operation of the NTC element 1221, enabling the NTC element 1221 to accurately detect the ambient temperature.

[0043] During operation of wind sensor 120, PTC element 1211 continuously detects the external wind speed and generates a first electrical signal. Second control unit 123 obtains the external wind speed based on the first electrical signal. Furthermore, NTC element 1221 continuously monitors the ambient temperature and generates a second electrical signal. This allows second control unit 123 to dynamically compensate the measurement result of PTC element 1211 based on the second electrical signal. This ensures that wind sensor 120 can accurately measure wind speed under varying ambient temperature conditions.

[0044] Specifically, because the measurement results of PTC element 1211 are affected by ambient temperature, these effects need to be compensated. NTC element 1221 can use the ambient temperature information represented by the second electrical signal to calculate a compensation coefficient to correct the measurement results of PTC element 1211 so that it reflects the actual wind speed rather than the error caused by external temperature changes.

[0045] After obtaining the external wind speed based on the first electrical signal and the second electrical signal, the second control unit 123 encapsulates the wind speed information in an electrical signal (the electrical signal is called the third electrical signal). The second control unit 123 sends the third electrical signal to the first control unit 114. The first control unit 114 parses the third electrical signal to obtain the wind speed information, and the first control unit 114 controls the atomization component 113 to work or not based on the wind speed information.

[0046] Specifically, the first control unit 114 presets a wind speed threshold. When the wind speed information is greater than or equal to the wind speed threshold, the first control unit 114 controls the atomizer assembly 113 to operate to atomize the essential oil in the essential oil bottle 112. When the wind speed information is less than the wind speed threshold, the first control unit 114 controls the atomizer assembly 113 to stop operating, so that the aroma diffuser 100 no longer emits mist. For example, the wind speed threshold is set to 0.3 m / s to indicate that wind reaching this wind speed threshold can blow small particles in the mist, causing them to diffuse outward.

[0047] In one embodiment, the first control unit 114 can also control the working power of the atomization component 113 based on the size of the wind speed information. For example, when the wind speed is large, the atomization component 113 can be controlled to increase the working power; when the wind speed is small, the atomization component 113 can be controlled to reduce the working power, so that the fragrance machine 100 is more intelligent.

[0048] In one embodiment, the second control unit 123 can directly send the first and second electrical signals to the first control unit 114, which processes the first and second electrical signals to generate a third electrical signal. The first control unit 114 then controls the operation of the atomizing assembly 113 based on the wind speed information represented by the third electrical signal.

[0049] In a further embodiment, in combination Figure 7 A differential circuit 130 is also provided within the housing 111. The differential circuit 130 is electrically connected to the first control unit 114. The differential circuit 130 can obtain the first electrical signal and the second electrical signal output by the wind sensor 120 via the first control unit 114, or the differential circuit 130 can directly obtain the first electrical signal and the second electrical signal. The differential circuit 130 processes the first electrical signal and the second electrical signal to further eliminate the influence of the ambient temperature on the wind speed measurement, so that the third electrical signal can more accurately reflect the change in the actual wind speed and eliminate errors. In this embodiment, it is recommended that the differential circuit 130 and the first control unit 114 be integrated on the same circuit board to facilitate circuit layout.

[0050] In this embodiment, the differential circuit 130 includes a differential amplifier 131. The differential amplifier 131 has two input terminals and one output terminal. The two input terminals receive the first electrical signal and the second electrical signal, respectively. The output terminal of the differential amplifier 131 is electrically connected to the first control unit 114. The differential amplifier 131 amplifies the difference between the first and second electrical signals, so that the output signal of the differential amplifier 131 primarily reflects the difference in resistance change between the PTC element 1211 and the NTC element 1221. As will be appreciated, by outputting the difference in resistance change between the NTC element 1221 and the PTC element 1211, the differential amplifier 131 effectively eliminates the effect of ambient temperature on wind speed measurement. Because the effects of ambient temperature changes on the NTC element 1221 and the PTC element 1211 are identical or similar, they are canceled out in the differential amplifier 131, resulting in a third electrical signal reflecting only wind speed.

[0051] Afterwards, the first control unit 114 controls the atomizing assembly 113 to operate or not operate by determining the wind speed based on the third electrical signal output by the differential amplifier 131 .

[0052] In one embodiment, the differential circuit 130 may be disposed in the wind sensor 120 and electrically connected to the second control unit 123, the first probe 121, and the second probe 122, respectively. In other words, the differential circuit 130 generates the third electrical signal in the wind sensor 120. The two input terminals of the differential amplifier 131 are electrically connected to the first probe 121 and the second probe 122, respectively, and the output terminal of the differential amplifier 131 is electrically connected to the second control unit 123.

[0053] In one embodiment, combined Figure 6 The wind sensor 120 is further provided with a mounting platform 124, with the first probe 121 and the second probe 122 disposed on the surface of the mounting platform 124. The PTC element 1211 is disposed at the end of the first probe 121, and the NTC element 1221 is disposed at the end of the second probe 122. The height of the first probe 121 relative to the surface is greater than the height of the second probe 122 relative to the surface, so that the PTC element 1211 and the NTC element 1221 are separated from each other to prevent heat generated by the PTC element 1211 from affecting the NTC element 1221's detection of the ambient temperature. In this embodiment, a distance of 10 mm or greater is recommended between the PTC element and the NTC element to prevent heat generated by the PTC element 1211 from affecting the operation of the NTC element 1221 and to maintain the detection accuracy of the NTC element 1221.

[0054] In one embodiment, combined Figure 3 and Figure 4 The wind sensor 120 is further provided with a separator 125, which is inserted into the first probe 121. The separator 125 is arranged above the NTC element 1221 of the second probe 122 and below the PTC element 1211 of the first probe 121, so that the PTC element 1211 and the NTC element 1221 are separated by the separator 125, so that the heat emitted by the PTC element 1211 will not be conducted to the NTC element 1221, so that the NTC element 1221 can well detect the external ambient temperature.

[0055] In a typical embodiment of the present invention, Figure 1 The wind sensor 120 is connected to the main body 110 by a cable 141. The wind sensor 120 can be installed in the air outlet area of ​​the indoor environment to effectively detect the flow of external air. For example, the wind sensor 120 can be installed in the air outlet of an air conditioner, in the air conditioner duct, in the exhaust area of ​​a fan, or in the vents of a house.

[0056] In one embodiment, the wind sensor 120 is wirelessly connected to the main body 110. A first communication unit (not shown) is provided in the housing 111 of the main body 110. The wind sensor 120 is also provided with a second communication unit (not shown). The first communication unit and the second communication unit are wirelessly connected to facilitate data transmission between the main body 110 and the wind sensor 120.

[0057] In this embodiment, the wind sensor 120 utilizes wireless communication with the main body 110. Compared to wired connections, the wind sensor 120 of this embodiment can be more flexibly arranged, thereby simplifying its arrangement. Furthermore, the cable 141 between the main body 110 and the wind sensor 120 is eliminated, thereby enhancing the aesthetics of the device. In this embodiment, it is recommended that both the first communication unit and the second communication unit be Bluetooth or Wi-Fi components, but this should not be construed as a limitation of this embodiment.

[0058] In summary, the fragrance machine of the present invention detects the wind speed of the external environment through the wind sensor to control whether the atomization component works or not, thereby improving the intelligence of the fragrance machine and enhancing the user experience.
