Description

TECHNICAL FIELD

[0001] The utility model relates to a fragrance equipment technical field, concretely relates to a fragrance machine. BACKGROUND

[0002] As an electrical product that can effectively improve the environment atmosphere and air quality, the fragrance equipment has been widely used in various places in recent years. Its core function is to atomize liquid freshener such as perfume and essential oil, and then release these tiny mist droplets into the air, so that the fresh fragrance can quickly spread, creating a more comfortable environment for users. From home to hotel rooms, from the lobby to the corridor, to the interior of private cars, fragrance equipment has become an important tool to improve the quality of life with its unique charm.

[0003] In the atomization technology of the fragrance equipment, there are currently two ways of ultrasonic atomization and pneumatic atomization. Among them, the ultrasonic atomization method has become the mainstream choice in the market due to its simple structure, convenient operation, and easy automatic control. This method quickly disperses liquid fragrance (such as essential oil) into tiny particles through the high-frequency vibration of the ultrasonic atomization sheet, achieving atomization effect, and then these mist droplets escape from the micro-holes of the atomization sheet and disperse into the surrounding environment.

[0004] In the practical application of ultrasonic atomization technology, some problems have also been exposed. In particular, the inverted ultrasonic atomization fragrance device that has appeared in recent years, although it has optimized the structure design and improved the atomization efficiency to some extent, still has the risk of liquid fragrance leakage. Since this device needs to invert the bottle containing liquid fragrance, the liquid can flow by gravity, and then be atomized. However, in actual use, the outflow port often shows obvious liquid leakage, which not only causes the surface of the fragrance device to be contaminated with oil and dirt, making it easy to get dirty and increasing the user's cleaning burden, but also causes waste of liquid fragrance, reducing the efficiency and economy of the equipment.

Since the concentration of the liquid fragrance conveyed to the atomizing sheet 7 is relatively low, the liquid fragrance is less likely to leak from the atomizing sheet 7.

[0041] The connecting area of the intermediate piece 50 and the liquid guiding core rod 6 is smaller than the connecting area of the intermediate piece 50 and the atomizing sheet 7; the intermediate piece 50 is a liquid guiding cotton sheet, and the cross section of the liquid guiding cotton sheet is larger than the cross section of the liquid guiding core rod 6.
