Abstract
Description
Technical Field
[0005]
[0001] The present invention relates to an air purification and aroma diffusion device, and particularly to a portable aromatherapy diffuser that is portable and can be easily used at any time.
Background Art
[0002] An aromatherapy diffuser, also called an aroma nebulizer or an aroma diffuser, is a device that diffuses essential oil molecules into the air by techniques such as ultrasonic atomization, anhydrous heat diffusion, or cold spray, and achieves effects such as aromatherapy, stress relief, increased environmental humidity, or removal of unpleasant odors. Common types include humidifying type, anhydrous diffusion type (pure essential oil type), and smart aromatherapy diffusers, which are suitable for spaces such as homes and offices.
Summary of the Invention
Problems to be Solved by the Invention
[0003] Regarding the humidifying type aromatherapy diffuser, since it has advantages such as a slight humidifying function, a relatively affordable price, silent operation, and the addition of an ambient night light, it has become the mainstay of the aromatherapy diffuser market. However, all the currently available humidifying type aromatherapy diffusers on the market are designed considering diffusing the fragrance throughout the installation space. Therefore, it is emphasized that the capacity of the fragrance diluent is large and the output of the ultrasonic vibrator is high. Such products are not small in volume and require connecting a power line to an external power grid to obtain power. For users who want to carry an aromatherapy diffuser out and always have a fragrance around them, there are almost no suitable products to meet such needs.
[0004] Therefore, in order to meet the above-mentioned needs, the present invention has been proposed.
Means for Solving the Problems
[0005] This paragraph provides a partial description of some features of the present invention. Other features will be disclosed in subsequent paragraphs. The purpose of this paragraph is to encompass the various modifications and similar configurations included in the spirit and scope of the attached utility model claims.
[0006] To meet the market demand for portable aroma diffusers, this invention provides an innovative portable aroma diffuser. This portable aroma diffuser comprises a fixed frame, a liquid supply module, an atomizing module, a power module, and a power control circuit. The fixed frame has a first connecting section, a second connecting section, and a main plate section. A liquid storage tank is formed below the second connecting section, and a removable liquid-absorbing wick is attached to the liquid storage tank. The liquid supply module is connected to the first connecting section and supplies the internal fragrance aqueous solution to the liquid storage tank. The atomizing module is attached to the second connecting section and contacts the liquid-absorbing wick, generating high-frequency vibrations by applying electricity to atomize the fragrance aqueous solution from the liquid-absorbing wick and diffuse it into the air. The power module is attached to one side of the main plate section. The power control circuit is attached to the other side of the main plate section and is electrically connected to the atomizing module and the power module. It is activated by switch control and supplies power from the power module to the atomizing module.
[0007] In this invention, the liquid supply module may further comprise a liquid conduit, a sealing ring, and a liquid storage container. The liquid conduit has a hollow structure and has a closed end and an open end, the open end being connected to a first connecting portion, and a plurality of liquid passage holes are formed between the closed end and the open end. The sealing ring surrounds a part of the outer circumference of the liquid conduit and is connected to the first connecting portion. The liquid storage container is detachably and sealedly connected to the sealing ring and is used to store and supply an aqueous fragrance solution, the aqueous fragrance solution flowing into the storage tank through these liquid passage holes.
[0008] In this invention, the power control circuit may further comprise a USB-C socket, two power supply pieces, a switch, and a power management module. The USB-C socket is partially exposed from the protective housing and is used to electrically connect to a USB-C plug at the power supply end or load end. The two power supply pieces are mounted within the second connecting section. The power management module is electrically connected to the power module, the USB-C socket, the switch, and these power supply pieces, and performs the following operations. A) A process that transmits power from the power module through these power supply pieces when the switch is on, and stops transmitting power from the power module through these power supply pieces when the switch is off. B) If the voltage of the USB-C plug electrically connected to the USB-C socket is determined to be greater than the voltage of the power module, the power from the USB-C socket is stored in the power module. The power management module may also perform the following actions: C) If the voltage of the USB-C plug electrically connected to the USB-C socket is determined to be lower than the voltage of the power module, the power module transmits power to the USB-C socket and supplies power to the load end in the reverse direction.
[0009] In this invention, the atomizing module may further comprise a base, a high-frequency transducer, a top cover, and a fixing ring piece. The base has two power receiving pins at its bottom, each power receiving pin being electrically connected to a corresponding power supply piece to obtain power. The bottom of the high-frequency transducer is electrically connected to the two power receiving pins, and its interior is in contact with the liquid-absorbing wick, generating high-frequency vibrations to atomize the fragrance aqueous solution inside the liquid-absorbing wick by vibration. The top cover is connected to the base and is used to guide the atomized fragrance aqueous solution to diffuse outwards. The fixing ring piece is mounted inside the top cover and is used to position and hold the high-frequency transducer, thereby preventing the high-frequency transducer from swinging between the top cover and the base.
[0010] Preferably, the material of the liquid-absorbing wick is cotton, sponge, foam, or filter paper, and the power module is a secondary battery module.
[0011] In one embodiment, curved surfaces with a small curvature are formed on both sides of the protective housing. Here, "curved surfaces with a small curvature" means a curvature (generally a radius of 50 mm or more) such that when the portable aroma diffuser is placed on a flat surface, the curved surface contacts the surface and can be placed stably without shaking. The first connecting portion may further include a plurality of fitting protrusions, and a plurality of fitting grooves may further be formed inside the protective lid. Each fitting protrusion is detachably fitted into a corresponding fitting groove, thereby allowing the protective lid to be indirectly connected to the protective housing. [Effects of the Invention]
[0012] The portable aroma diffuser of this invention can be made smaller in volume by using a dedicated liquid supply module and atomization module, and can be made into a structure and appearance that can be carried by hand. The fragrance solution diffused from the portable aroma diffuser is insufficient to widely diffuse throughout a relatively large space, but it can sufficiently cover the area in which the user can perceive the scent (generally within 1 meter around the user). The liquid storage container in the liquid supply module can be screwed into a sealing ring, and the liquid conduit is easy to clean. Therefore, different fragrance solutions can be stored in different liquid storage containers, allowing for easy switching between different scents, and minimizing the problem of scents mixing. This invention has low noise levels during operation and is easy to use when placed on any surface. Furthermore, the portable aroma diffuser can also be used as an emergency mobile battery, and can be powered in reverse to an external load terminal via a USB-C socket.

[0014] The present invention will be described more specifically by referring to the following embodiments.
[0015] Please refer to Figures 1 and 2. Figure 1 is a perspective view of a portable aroma diffuser 1 according to an embodiment of the present invention, and Figure 2 is an exploded perspective view of the portable aroma diffuser 1. The portable aroma diffuser 1 comprises a fixed frame 10, a liquid supply module 20, an atomizing module 30, a power module 40, a power control circuit 50, a protective housing 60, and a protective cover 70. The form, function, and interaction mechanism of the above-mentioned technical elements with other technical elements will be described below with reference to the relevant drawings.
[0016] Please refer to Figures 3 and 4. Figure 3 is a perspective view showing the power module 40 and power control circuit 50 combined with the fixed frame 10, and Figure 4 is a perspective view of the fixed frame 10. The fixed frame 10 is the main body that supports and fixes the other components of the portable aroma diffuser 1, and in form it has a first connecting part 11, a second connecting part 12, and a main plate part 13. The first connecting part 11 is located at one end of the fixed frame 10 and is used to connect the liquid supply module 20. The first connecting part 11 externally includes a connecting platform 111 and a circular groove 112 with a recess in the center. The connecting platform 111 has a plurality (two in this embodiment) fitting projections 113 formed thereon for fitting with the protective cover 70, and a through hole 114 is provided at the bottom of the circular groove 112. The second connecting part 12 is located next to the first connecting part 11 and has a double ring structure, including an outer ring 122 and an inner ring 123. The outer ring 122 is used to mount the atomizing module 30, and a removable liquid-absorbing wick 124 is inserted into the inner ring 123. Two power supply pieces 52 of the power control circuit 50 are mounted between the inner ring 123 and the outer ring 122. Below the second connecting section 12, a storage tank 121 is formed for temporarily storing the fragrance aqueous solution from the liquid supply module 20. The inner ring 123 is connected to the storage tank 121, meaning the liquid-absorbing wick 124 is attached to the storage tank 121. The liquid-absorbing wick 124 can guide the fragrance aqueous solution in the liquid supply module 20 to the atomizing module 30 for atomization. In practice, the material of the liquid-absorbing wick 124 may be cotton, sponge, foam, or filter paper, and it is formed in a cylindrical shape that can be inserted into the inner ring 123. The main plate section 13 extends from one side of the second connecting section 12 and is used to mount the power module 40 and the power control circuit 50.
[0017] FIG. 5 is an exploded perspective view of the liquid supply module 20. The liquid supply module 20 is connected to the first connecting portion 11, and its function is to allow the internal aqueous perfume solution to flow into the liquid storage tank 121 through the through hole 114. To achieve the above-described object, the liquid supply module 20 includes a liquid guiding pipe 21, a sealing ring 22, and a liquid storage container 23. The liquid guiding pipe 21 has a hollow structure and has a closed tip 211 and an open end 212. The open end 212 is connected to the first connecting portion 11, and a plurality of liquid through holes 213 are formed between the closed tip 211 and the open end 212. In the present embodiment, there are three liquid through holes 213, which are evenly formed on the wall of the liquid guiding pipe 21. The sealing ring 22 surrounds a part of the outer periphery of the liquid guiding pipe 21 and is connected to the first connecting portion 11. The purpose of the sealing ring 22 is to closely adhere to the liquid storage container 23 to prevent the aqueous perfume solution in the liquid storage container 23 from flowing out. The liquid storage container 23 is detachably and sealingly connected to the sealing ring 22 and is used to store and supply the aqueous perfume solution. The aqueous perfume solution flows into the liquid storage tank 121 through these liquid through holes 213. In fact, an external thread is formed on the outside of the sealing ring 22, and a corresponding internal thread is formed inside the liquid storage container 23. Therefore, the two are connected in a rotational manner and can maintain a sealed state. Since the liquid guiding pipe 21 deeply penetrates into the liquid storage container 23, the aqueous perfume solution can easily flow into the liquid through holes 213, and there will be no problem that the aqueous perfume solution is difficult to flow into the liquid guiding pipe 21. When the aqueous perfume solution in the liquid storage container 23 is completely consumed, the liquid storage container 23 can be removed from the sealing ring 22 for replenishment. When the user wants to replace it with a different aqueous perfume solution, the liquid storage container 23 can be removed and washed, and the liquid guiding pipe 21 can also be washed. Thereby, no previous aqueous perfume solution remains in the liquid supply module 20 after washing. On the other hand, some previous aqueous perfume solution may remain in the second connecting portion 12. The user can wash the liquid storage tank 121 with clean water through the first connecting portion 11. In addition, since the previous aqueous perfume solution remains in the old liquid absorption core 124, if the liquid absorption core 124 is replaced, a new liquid absorption core 124 can continuously absorb a new aqueous perfume solution. In this way, the portable aroma diffuser 1 can atomize and diffuse a new aqueous perfume solution into the air.
[0018] Please refer to FIGS. 6 and 7. FIG. 6 is a view showing the state where the atomization module 30 is attached to the fixed frame, and FIG. 7 is an exploded perspective view of the atomization module 30. The atomization module 30 is attached to the second connecting portion 12 and contacts the liquid absorption core 124. After being energized, the atomization module 30 can generate high-frequency vibrations, atomize the perfume aqueous solution from the liquid absorption core 124, and diffuse it into the air. As shown in FIG. 7, the atomization module 30 further includes a base 31, a high-frequency oscillator 32, an upper cover 33, and a fixed ring piece 34. Below the base 31, two power receiving pins 311 are provided. Each power receiving pin 311 is electrically connected to a corresponding one of the power supply pieces 52 to obtain power. The bottom of the high-frequency oscillator 32 is electrically connected to the two power receiving pins 311, and the inside contacts the liquid absorption core 124. The high-frequency oscillator 32 generates high-frequency vibrations after being energized, thereby atomizing the perfume aqueous solution in the liquid absorption core 124 by vibration. The upper cover 33 is connected to the base 31 and is used to guide the atomized perfume aqueous solution to diffuse to the outside. The fixed ring piece 34 is attached inside the upper cover 33 and is used to position and hold the high-frequency oscillator 32, thereby preventing the high-frequency oscillator 32 from swinging between the upper cover 33 and the base 31.
[0019] The power module 40 is used to store power and supply power to the power control circuit 50. The power module 40 is attached to one side of the main board portion 13, and its specific form may be a secondary battery module.
[0020] The power control circuit 50 is mounted on the other side of the main plate 13 and is electrically connected to the atomizing module 30 and the power module 40. The power control circuit 50 is activated by control of the switch 53 and supplies power from the power module 40 to the atomizing module 30, and further atomizes and diffuses the fragrance aqueous solution. Refer to Figure 8. This figure is a block diagram of the power control circuit 50. The power control circuit 50 is shown by a dashed frame and comprises a USB-C socket 51, the two power supply pieces 52 mentioned above, a switch 53, and a power management module 54. As shown in Figure 1, the USB-C socket 51 is partially exposed from the protective housing 60 and is used to electrically connect to a USB-C plug (not shown) at the power supply end or load end. As mentioned above, the two power supply pieces 52 are mounted in the second connecting section 12 and connected to two power receiving pins 311. As shown in Figure 1, a portion of the switch 53 is exposed from the protective housing 60, and the user can control the starting and stopping of the power control circuit 50 by operating the switch 53.
[0021] The power management module 54 is electrically connected to the power module 40, the USB-C socket 51, the switch 53, and their power supply pieces 52, and may include at least one controller and a corresponding passive element. The power management module 54 primarily performs the following processes. In the first process, when the switch 53 is on, it transmits power from the power module 40 via the power supply pieces 52, and when the switch 53 is off, it stops transmitting power from the power module 40 via the power supply pieces 52. The direct recipient of the power is the power receiving pin 311, and this power is consumed by the high-frequency oscillator 32. In the second process, if it is determined that the voltage of the USB-C plug electrically connected to the USB-C socket 51 is greater than the voltage of the power module 40, it stores power from the USB-C socket 51 (power from the power supply terminal) in the power module 40. This process is for charging the power module 40. In the third process, if it is determined that the voltage of the USB-C plug electrically connected to the USB-C socket 51 is lower than the voltage of the power module 40, power from the power module 40 is transmitted to the USB-C socket 51 and supplied to the load end in the reverse direction via the USB-C plug. As a result, the portable aroma diffuser 1 can also be considered as a mobile battery.
[0022] The protective housing 60 covers the fixed frame 10, the fluid supply module 20, the power module 40, and the power control circuit 50, leaving parts of the fixed frame 10 and the fluid supply module 20 exposed. The protective cover 70 is detachably connected to the fixed frame 10 to protect part of the fluid supply module 20. As shown in Figure 2, the first connecting portion 11 has a plurality of fitting protrusions 113, and correspondingly, a plurality of fitting grooves 71 are formed inside the protective cover 70. Each fitting protrusion 113 is detachably fitted into a corresponding fitting groove 71, thereby allowing the protective cover 70 to be indirectly connected to the protective housing 60.
[0023] One of the technical features of this invention lies in the design of the protective housing 60. Please refer to Figure 9. This figure shows the portable aroma diffuser 1 in a state where it is placed on a mounting surface G. Small curved surfaces (generally with a radius of 50 mm or more) are formed on both sides of the protective housing 60. As a result, when the portable aroma diffuser 1 comes into contact with the mounting surface G (for example, the surface of a desk) on these curved surfaces, the portable aroma diffuser 1 is placed stably without shaking. In this way, the user can place the portable aroma diffuser 1 on any flat surface, turn on the switch 53, and then diffuse the atomized fragrance aqueous solution into the surrounding space.
