Description
- The present invention relates to electronic cigarettes, in particular to an ultrasonic atomizer and an electronic cigarette.
- The existing electronic cigarette generally realizes ultrasonic atomization of e-liquid by means of contact between an ultrasonic atomization sheet and liquid guiding cotton. However, unstable liquid guiding rate of the liquid guiding cotton can easily lead to over-loaded or insufficient e-liquid on the atomization surface of the ultrasonic atomization sheet, which will cause insufficient atomization, so that users may inhale e-liquid particles or smell the burnt taste.
- In addition, the liquid guiding cotton is arranged in an atomization region on the surface of the ultrasonic atomization sheet. When the ultrasonic atomization sheet is working continuously, the liquid guiding cotton may be scorched. Meanwhile, after the liquid guiding cotton is placed for a long time, the e-liquid soaks the atomization region, so that deposits cover the surface of the atomization region. Therefore, when the ultrasonic atomization sheet is activated, atomization of the e-liquid is slow, and the generated smoke is little.
- The technical problem to be solved by the present invention is, in view of the deficiencies in the prior art that liquid guiding cotton must be arranged in an atomization region, to provide an ultrasonic atomizer which can ensure normal operation of ultrasonic atomization without placing liquid guiding cotton in an atomization region of an ultrasonic atomization sheet, and an electronic cigarette.

- When the ultrasonic atomization sheet oscillates at a high frequency, the ceramic liquid guiding member will also oscillate, making e-liquid in the liquid bin to flow to the ultrasonic atomization sheet. Because the e-liquid in the atomization region of the ultrasonic atomization sheet has the best atomization effect, thus making the heat generated in the atomization region is the most, so that the temperature of the atomization region of the ultrasonic atomization sheet is relatively high, which accelerates the atomization process of e-liquid. In addition, due to the high viscosity of e-liquid, when the ultrasonic atomization sheet is working, the e-liquid in the atomization region will produce a traction force on the e-liquid on the ceramic liquid guiding member, so that the e-liquid on the ceramic liquid guiding member is continuously and automatically drawn to the atomization region of the ultrasonic atomization sheet. Therefore, normal ultrasonic atomization of the e-liquid can be ensured without covering the atomization region by a liquid storage member that stores e-liquid (a flexible medium such as atomization cotton), which can reduce the phenomenon that the liquid storage member is scorched to affect the taste of vapor. Meanwhile, the ultrasonic atomization sheet of the present invention is placed vertically, so that the e-liquid will not be deposited on the atomization surface of the ultrasonic atomization sheet, the ultrasonic atomization of the ultrasonic atomization sheet is activated faster, and vapor can flow out of the atomization cavity faster, thereby improving user experience.

Theplug 12 is preferably an elastic silica gel plug. Twoslots 121 penetrating theplug 12 are vertically provided in theplug 12, the twoslots 121 are arranged in parallel, andprotrusions 123 are respectively provided in the twoslots 121. Arib 122 is provided between upper parts of the twoslots 121, and the lower parts of the twoslots 121 are communicated to form a yielding space, which facilitates the assembly of anultrasonic atomization sheet 33. - The
liquid guiding assembly 2 includes two ceramicliquid guiding members 21 arranged oppositely. When the ceramicliquid guiding members 21 are inserted into theslots 121, the lower sections of the two ceramicliquid guiding members 21 are opposite to form acontact portion 22. Thecontact portion 22 is used to place theultrasonic atomization sheet 33 of theatomization assembly 3, so that the ceramicliquid guiding members 21 guide e-liquid to theultrasonic atomization sheet 33 for ultrasonic atomization. Aliquid storage cavity 211 is provided inside each ceramicliquid guiding member 21, so that the contact area between the e-liquid and the ceramicliquid guiding member 21 is larger, thereby improving the liquid guiding effect of the ceramicliquid guiding member 21. - The two ceramic
liquid guiding members 21 are correspondingly inserted into the twoslots 121, and each of the two ceramicliquid guiding members 21 is clamped by theprotrusion 123 in thecorresponding slot 121 and therib 122, so that the ceramicliquid guiding members 21 are fixed in theslots 121. - The
atomization assembly 3 includes abase 31, a sealingseat 32 arranged on thebase 31, and anultrasonic atomization sheet 33 inserted in the sealingseat 32 and thebase 31.

Because theultrasonic atomization sheet 33 is in a high-frequency oscillation state, the e-liquid in theatomization region 331 draws the e-liquid on the ceramicliquid guiding members 21 to theatomization region 331 by means of the traction force of the e-liquid to participate in ultrasonic atomization. When theultrasonic atomization sheet 33 is working, the atomization effect in theatomization region 331 is the best, and more heat is generated in theatomization region 331, so the temperature of theatomization region 331 is relatively high, which accelerates the atomization process of e-liquid. In addition, the e-liquid is automatically supplied by means of the traction force of the e-liquid when theultrasonic atomization sheet 33 oscillates at the high frequency. Therefore, no liquid storage member is required to be placed in theatomization region 331, so as to reduce the phenomenon that the e-liquid storage member is scorched. - An
