Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electronic cigarettes, and particularly relates to a detachable oil guiding device and an electronic cigarette using the same. BACKGROUND

[0002] The existing sound surface wave electronic cigarette atomization area oil guiding hole or oil guiding piece is not detachable, and a thick liquid film is formed. For example, a sound surface wave electronic cigarette atomization sound surface wave chip is disclosed in Chinese Patent No. CN201810167785.X, which is provided with an oil guiding hole on a piezoelectric substrate sheet. The oil guiding hole contains tobacco liquid drops. The oil guiding hole is not detachable, and a thick liquid film is formed, which causes the oil guiding hole to easily accumulate residues. When atomized again, harmful substances may be produced. In addition, the pump supplies oil from the bottom to the top, and the liquid film thickness cannot be stably maintained.

[0003] In addition, when the traditional oil guiding piece is a wicking material or a porous ceramic, the oil guiding piece is arranged above the atomization area or directly placed on the surface of the sound surface wave chip. When the liquid drops fall on the atomization area, if the liquid drops do not spread on the surface in time to form a liquid film, the sound surface wave will drive the liquid drops to flow, delaying the atomization rate of the sound surface wave and the liquid film, thereby affecting the atomization effect. At the same time, the sound surface wave chip generates a lot of heat during operation, which causes the sound surface wave chip to easily crack. SUMMARY

The top surface of the oil guiding piece is continuous with the top surface of the sound surface wave chip. The metal plate is attached to the bottom surface of the sound surface wave chip.

[0007] Further, the top surface of the oil guiding piece is planar.

[0008] Further, the top surface of the oil guiding piece is a meniscus shape concave to the bottom of the oil guiding cylinder.

[0011] Further, the oil guiding piece comprises a plurality of second metal columns perpendicular to the bottom surface of the oil guiding cylinder, and a wicking material in the form of a wire is wound around the second metal columns.

[0012] Further, the oil guide is a plurality of oil guiding microchannels.

[0013] Further, the oil guide is a porous ceramic.

Detailed Implementation

[0030] The present invention will be further described below with reference to specific embodiments, but the scope of protection of the present invention is not limited thereto.

[0031] Example 1

[0032] like Figures 1-3 As shown, this embodiment of the detachable oil guiding device includes an oil guiding component and a metal support component. The metal support component includes an oil guiding cylinder 1 and a metal plate 2 located around the circumference of the oil guiding cylinder 1. The top of the oil guiding cylinder 1 is embedded in the through hole of the surface acoustic wave (SAW) chip 11. The oil guiding component is detachably installed in the oil guiding cylinder 1 of the metal support component. The top surface of the oil guiding component is continuous with the top surface of the SAW chip 11, and the metal plate 2 is in contact with the bottom surface of the SAW chip 11. The SAW chip 11 has a through hole for the oil guiding cylinder 1 to be embedded. After the oil guiding cylinder 1 is embedded, the metal plate 2 is completely in contact with the bottom surface of the SAW chip 11. The SAW chip 11 is provided with interdigitated transducers, which are multiple pairs of strips arranged in the shape of interlaced fingers of two hands, used to generate surface acoustic waves to achieve e-liquid atomization.

[0033] In use, the oil guide is inserted into the oil guide cylinder 1, and the oil guide cylinder 1 is inserted into the surface acoustic wave chip 11 until the metal plate 2 is attached to the bottom surface of the surface acoustic wave chip 11. Then, the interdigital transducer is turned on, and the surface acoustic wave generated by the interdigital transducer atomizes the tobacco tar in the oil guide and provides the user with a smoke for smoking. In this embodiment, the metal support is detachable from the surface acoustic wave chip 11, and the oil guide can be inserted into the atomization area of the surface acoustic wave chip 11 through the metal support. The surface acoustic wave chip 11 does not need to be provided with an oil storage space, thereby reducing the weight of the surface acoustic wave chip 11. In the atomization process, the top surface of the oil guide is continuous with the upper surface of the surface acoustic wave chip 11, and the top surface of the oil guide can continuously maintain a thin liquid film, thereby increasing the contact rate of the surface acoustic wave and the liquid film and increasing the atomization amount. The metal plate 2 outside the oil guide cylinder 1 absorbs the heat of the surface acoustic wave chip 11 and transfers the heat to the oil guide, thereby dissipating the heat of the surface acoustic wave chip 11 and supplying heat to the tobacco tar, improving the atomization effect, and avoiding dry burning.

[0034] The top surface of the oil guide in the oil guide cylinder 1 is flat or concave to the bottom of the oil guide cylinder 1. The liquid surface formed by the tobacco tar on the top surface of the oil guide is flat or concave to the bottom of the oil guide cylinder 1, thereby improving the surface tension of the liquid film on the top surface of the oil guide. Figure 9 As shown in FIG. 1, the overall shape of the oil guide can be square or circular, and the shape of the oil guide cylinder 1 is adapted to the overall shape of the oil guide. The shape of the through hole of the surface acoustic wave chip 11 is adapted to the shape of the oil guide cylinder 1. In this embodiment, the oil guide is preferably circular, and the surface acoustic wave chip 11 is also circular. The plurality of interdigital transducers are uniformly distributed along the circumference of the surface acoustic wave chip 11.

[0035] In this embodiment, the oil guide is a porous wick 5 similar to cotton, the porous wick 5 is soaked with tobacco tar, and the top surface of the porous wick 5 is flat or concave to the bottom of the oil guide cylinder 1. The liquid surface formed by the tobacco tar on the top surface of the porous wick 5 is flat or concave to the bottom of the oil guide cylinder 1. The top surface of the porous wick 5 can also be a flat surface with a certain roughness.

In this embodiment, the wicking component includes a porous wick 5 and several first metal pillars 3. The first metal pillars 3 are located within the porous wick 5, and the angle between each of the first metal pillars 3 and the bottom surface of the wicking cylinder 1 is less than 90 degrees, meaning each first metal pillar 3 is placed at an angle to maintain the surface tension of the e-liquid at the top of the porous wick 5. The top surfaces of the first metal pillars 3 are on the same plane, and the overall shape of the e-liquid surface formed on the top surfaces of the first metal pillars 3 is planar. Alternatively, the top surfaces of the first metal pillars 3 can be connected to form a crescent shape that leads to a concave bottom of the wicking cylinder 1, and the overall shape of the e-liquid surface formed on the top surfaces of the first metal pillars 3 is crescent-shaped.

[0038] Example 3

[0039] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 lies in the structure of the wicking component. In this embodiment, the wicking component includes several second metal pillars 4 and a linear wicking element 6. All the second metal pillars 4 are perpendicular to the bottom surface of the wicking cylinder 1. The linear wicking element 6 is wrapped around the second metal pillars 4. The top surfaces of the several second metal pillars 4 are on the same plane, and the overall shape of the liquid surface formed by the e-liquid on the top surfaces of the several second metal pillars 4 is planar. Alternatively, the top surfaces of the several second metal pillars 4 can be connected to form a crescent shape that leads to a concave bottom of the wicking cylinder 1, and the overall shape of the liquid surface formed by the e-liquid on the top surfaces of the several second metal pillars 4 is crescent-shaped.

[0040] Example 4

[0041] like Figure 6 As shown, the difference between this embodiment and Embodiment 1 lies in the structure of the oil guiding component.
