Description

Technical Field

[0001] The utility model relates to the technical field of aromatherapy devices, in particular to a self-breathing diffusing aromatherapy machine. Background Art

[0002] Most of the aromatherapy machines used in life at present generate high-frequency electronic oscillations through ultrasonic oscillation devices, decompose water molecules and dissolved plant essential oils into nano-scale cold mists with a diameter of 0.1-5 microns, and disperse them into the surrounding air, making the air full of various scents. However, the molecular structure of the molecules formed after ultrasonic high-frequency oscillation treatment will be damaged to a certain extent, resulting in an unstable state, easily reacting with other chemical substances, thus affecting the spread of its original scent. Seriously, qualitative changes may even occur, and it cannot be used continuously for a long time.

[0003] For traditional aromatherapy devices that utilize the principle of natural volatilization and diffusion, due to their extremely slow natural diffusion speed, they simply cannot meet the usage needs of consumers and are often useless. To overcome this defect, some manufacturers will add a blowing device on the basis of natural diffusing aromatherapy devices. However, the aromatherapy devices after adding the blowing device will have defects such as too large product volume and excessive fan noise during use. Although the defect of slow diffusion speed is solved, new defects are also added at the same time. Therefore, most of the aromatherapy devices on the market can meet the usage needs of consumers on the premise of ensuring quality. Content of the Utility Model

Detailed Embodiments

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1-2 , a self-breathing diffusing aromatherapy machine, which includes an aroma storage cavity (1). The aroma storage cavity (1) includes an aroma storage cavity housing (13). A vibrating diaphragm (15) is encapsulated in the opening area at the bottom surface of the aroma storage cavity housing (13). The vibrating diaphragm (15) is drivingly connected to a vibration driving device (16). A diffusion through-hole (131) is provided at the upper end of the aroma storage cavity housing (13). An aroma liquid is loaded above the vibrating diaphragm (15) inside the aroma storage cavity (1). When the vibration driving device (16) drives the vibrating diaphragm (15) to generate an offset vibration, the aroma liquid generates a bouncing motion above the vibrating diaphragm (15), thereby stimulating the diffusion activity of the aroma liquid particles.

[0022] A fragrance storage component (12) is covered above the diffusion through-hole (131). The fragrance storage component (12) includes a perfume cotton tray (122) covered on the diffusion through-hole (131) and a perfume cotton (121) arranged on the perfume cotton tray (122). The perfume cotton tray (122) is a hollow-structured tray. The hollow structure enables the perfume cotton (121) to be communicated with the internal space of the aroma storage cavity (1). When the vibrating diaphragm (15) vibrates, the aroma liquid above the vibrating diaphragm (15) is scattered by the vibrating diaphragm (15) and bounces upward. During the bouncing process of the aroma liquid, some aroma liquid droplets with greater force will be ejected onto the perfume cotton (121) indiscriminately and absorbed and temporarily stored in the perfume cotton (121) by the perfume cotton (121). At the same time, the vibrating diaphragm (15) constantly changes the volume of the aroma storage cavity (1) during the vibration process. During the process of the volume of the aroma storage cavity (1) changing from large to small and then from small to large, a breathing rhythm of blowing air flow will be formed at the diffusion through-hole (131). When the blowing air flow acts on the perfume cotton (121), it can accelerate the vaporization and outward diffusion of the aroma liquid in the perfume cotton (121), thereby playing a role in accelerating diffusion. In addition, in addition to ejecting the aroma liquid onto the perfume cotton (121) by the vibrating diaphragm (15), the perfume storage component (12) can also be stored with the aroma liquid by directly dropping the aroma liquid onto the perfume cotton (121). An air outlet face cover (11) is covered above the perfume storage component (12). A slit-shaped air outlet (17) is formed between the air outlet face cover (11) and the perfume storage component (12). The blowing air flow carries the aroma gas and blows it outwards from the air outlet (17).

[0023] The outer shell (13) of the aroma storage cavity is a transparent housing, through which the bouncing scene of the aromatherapy liquid droplets can be observed.

[0024] The lower end of the fragrance storage cavity (1) is connected to an electrical appliance cavity (2). The electrical appliance cavity (2) includes an electrical appliance cavity outer shell (24). The electrical appliance cavity outer shell (24) includes an upper electrical appliance cavity shell (241) and a lower electrical appliance cavity shell (242) that are hermetically connected to each other. A cavity is formed between the upper electrical appliance cavity shell (241) and the lower electrical appliance cavity shell (242). An anti-slip gasket (25) is provided on the bottom surface of the lower electrical appliance cavity shell (242). The vibration driving device (16) is arranged on the side of the vibration membrane (15) facing the electrical appliance cavity (2) and is located inside the electrical appliance cavity (2). The vibration driving device (16) includes a magnetic field coil assembly (161) fixedly connected to the vibration membrane (15) and a magnetic attraction assembly fixedly connected to the electrical appliance cavity outer shell (24). The magnetic attraction assembly includes a magnetic conductive lower shell (164), a permanent magnet (163) installed on the magnetic conductive lower shell (164), and a magnetic conductive upper shell (162) covering the side of the permanent magnet (163) away from the magnetic conductive lower shell (164). The magnetic conductive lower shell (164) is fixedly connected to the electrical appliance cavity outer shell (24). A circuit board assembly (22) and a storage battery (23) are arranged inside the electrical appliance cavity (2). The storage battery (23) is electrically connected to the circuit board assembly (22). The vibration driving device (16) is electrically connected to the circuit board assembly (22). A control button (221) and a USB interface (222) are electrically connected to the circuit board assembly (22). The control button (221) and the USB interface (222) are both arranged in preset through holes of the electrical appliance cavity outer shell (24) and protrude outwards from the through holes. A storage chip (223) and a voice microphone (224) are encapsulated on the circuit board assembly (22). The storage chip (223) is used to store audio files, which can store specified audio files during factory settings or copy the audio files selected by the user to the storage chip (223) through the USB interface (222). The voice microphone (224) is used to receive external audio signals, such as the voices of people speaking and singing. The circuit board assembly (22) is internally provided with an audio conversion circuit, which can convert the audio files on the storage chip (223) or the audio signals received by the voice microphone (224) into current signals, and then use the current signals to change the magnetic field of the magnetic field coil assembly (161), so as to cooperate with the magnetic attraction assembly to drive the vibration membrane (15), so that the vibration membrane (15) can generate different amplitude vibrations according to different audio frequencies. The control button (221) is a composite button. By pressing or rolling methods set during factory settings, it can control the audio acquisition path, the working mode of the vibration driving device (16), and the working mode of the LED light-emitting beads (225). The USB interface (222) can be connected to an external power supply through a data cable to charge the storage battery (23), or connected to a data interface to realize data exchange of the storage chip (223).

[0025] The circuit board assembly (22) is arranged circumferentially around the diaphragm (15). An LED light-emitting bead (225) is encapsulated on the circuit board assembly (22). The LED light-emitting beads (225) are evenly arranged in the circumferential direction of the diaphragm (15), and the light-emitting direction is set towards the side of the fragrance storage cavity (1). A packaging ring (21) is clamped at the joint between the diaphragm (15) and the circuit board assembly (22). The packaging ring (21) serves to seal the joint seam between the diaphragm (15) and the circuit board assembly (22), preventing the perfume liquid in the fragrance storage cavity (1) from leaking out of the fragrance storage cavity (1). A light guide member (14) is disposed above the LED light-emitting bead (225). When the LED light-emitting bead (225) emits light, the light passes through the light guide member (14) and shines towards the fragrance storage cavity (1), serving to create a light atmosphere.

[0026] To sum up: In the present utility model, a diaphragm (15) capable of generating vertical amplitude vibration is provided at the bottom of the fragrance storage cavity 1. The vibration of the diaphragm (15) drives the perfume liquid in the fragrance storage cavity 1 to generate a bouncing motion, thereby stimulating the diffusion activity of the perfume liquid particles. At the same time, the bouncing perfume liquid droplets can splash onto the fragrance storage assembly 12 located at the diffusion through-hole 131. During the vibration of the diaphragm (15), the internal volume of the fragrance storage cavity 1 can be changed, thereby forming a breathing air flow at the diffusion through-hole 131. The existence of the breathing air flow can not only rhythmically blow the fragrance storage assembly 12 to promote the fragrance dispersion of the fragrance storage assembly 12, but also realize the ventilation of the internal space of the fragrance storage cavity 1, so as to accelerate the outward diffusion of the fragrance inside the fragrance storage cavity 1, thereby achieving rapid fragrance diffusion on the premise of ensuring the fragrance quality. Moreover, through the transparent fragrance storage cavity housing 13, the bouncing scene of the perfume liquid can be observed, and with the rendering of the ambient light, the product becomes more interesting and ornamental, effectively improving the cost performance of the product.
