Embodiment 1

(10) An inclined ultrasonic atomizing sheet structure, as shown in FIG. 3, includes atomization cotton 14, a piezoelectric ceramic 16, and tobacco tar guide cotton 17. The lower end of the tobacco tar guide cotton 17 is immersed in a tobacco tar cavity, and two ends of the atomization cotton 14 are in contact with the tobacco tar guide cotton 17, so that the tobacco tar is transferred to the atomization cotton 14 through the tobacco tar guide cotton 17, and then the piezoelectric ceramic 16 can atomize the tobacco tar in the atomization cotton 14 to produce smoke, thus well controlling the flow rate of the tobacco tar to affect the atomization rate.

(11) The atomization cotton 14 of the present invention is pressed on an atomization surface of the piezoelectric ceramic 16 through a pressing spring 13, thus avoiding poor contact between the atomization cotton 14 and the piezoelectric ceramic 16 due to vibration of the piezoelectric ceramic 16 in operation of the atomizer, thus the atomization effect or life of the piezoelectric ceramic 16 cannot be affected.

(12) The piezoelectric ceramic 16 of the present invention is a solid piezoelectric ceramic, which is driven by an electric conductor to form an ultrasonic atomizing sheet. The piezoelectric ceramic 16 of the present invention is obliquely arranged at an inclination angle of A, preferably, 0°<A<90°, and more preferably, 50°≤A≤75°.

(13) Within this angle range, two ends of the atomization cotton are in contact with the tobacco tar guide cotton to realize a tobacco tar guide function. When the atomizer is in operation, sufficient tobacco tar supply is ensured. When the atomizer is not in operation, excess tobacco tar on the piezoelectric ceramic is returned to the tobacco tar guide cotton through the atomization cotton at the lower end of the inclined portion, so that the surface of the piezoelectric ceramic is not soaked in the tobacco tar, and a sufficient amount of tobacco tar is supplied for atomization.

(14) A piezoelectric ceramic mounting cavity 34 for placing the piezoelectric ceramic 16 in a housing 18 is also arranged obliquely. A penetration groove 35 is formed all around the bottom of the piezoelectric ceramic mounting cavity 34, and the atomization cotton 14 penetrates through the penetration groove 35 and is in contact with the tobacco tar guide cotton 17 to supply enough tobacco tar for the ultrasonic atomizing sheet.

(15) The atomization cotton of the present invention is in contact with a part of the surface of the piezoelectric ceramic to improve the operating rate of the piezoelectric ceramic, thereby improving the user experience.

(16) The internal thread of the housing 18 is connected with a locking ring 12, and the external thread of the housing 18 is connected with the suction nozzle 11. The suction nozzle 11 of the present invention can be removed for cleaning.

(17) An air tube 31 communicated with a suction passage is arranged in the center of the locking ring 12, an air passing slot 32 is formed in a side wall of the locking ring 12, an air inlet slot 30 is formed between the suction nozzle 11 and the housing 18, and the air inlet slot 30 is communicated with the air passing slot 32.

(18) The air tube 31 of the present invention is not in contact with the surface of the atomization cotton 14, and the distance between the air tube 31 and the atomization cotton 14 is preferably 0.2 to 5 mm, ensuring that most of airflow passes through the surface of the atomization cotton 14 and carries the ultrasonically atomized smoke away.

(19) The lower end of the tobacco tar guide cotton 17 of the present invention is in contact with the tobacco tar in the tobacco tar cavity, so that the tobacco tar can be absorbed by the tobacco tar guide cotton 17.

(20) In the present invention, the piezoelectric ceramic 16 is obliquely arranged, preferably at an inclination angle of more than or equal to 50° and less than or equal to 75° relative to the horizontal plane. Within this angle range, the two ends of the atomization cotton 14 are in contact with the tobacco tar guide cotton 17 to realize a tobacco tar guide function. When the atomizer 1 is in operation, sufficient tobacco tar supply is ensured. When the atomizer 1 is not in operation, excess tobacco tar on the piezoelectric ceramic 16 is returned to the tobacco tar guide cotton 17 through the atomization cotton 14 at the lower end of the inclined portion, thus preventing the piezoelectric ceramic 16 from being soaked in the tobacco tar.

(21) An electronic cigarette, as shown in FIG. 1 and FIG. 4, includes the above atomizer 1 and a battery assembly 2, wherein the atomizer 1 is magnetically connected with the battery assembly 2 to facilitate disassembly.

(22) The battery assembly of the present invention includes a battery cover 26, a large bracket 25, and a battery 27.

(24) A charging assembly 28 for charging the battery 27 is mounted at the bottom of the battery cover 26.

Embodiment 2

(25) An inclined ultrasonic atomizing sheet structure, as shown in FIG. 7, includes atomization cotton 14 and a piezoelectric ceramic 16. Two ends of the atomization cotton 14 are directly immersed in the tobacco tar cavity, the tobacco tar is transferred to the piezoelectric ceramic 16 by the atomization cotton 14, and the tobacco tar in the atomization cotton 14 is atomized to produce smoke, thus well controlling the flow rate of the tobacco tar to affect the atomization rate.

(26) The atomization cotton 14 of the present invention is pressed on an atomization surface of the piezoelectric ceramic 16 through a silica gel seat 13, thus avoiding poor contact between the atomization cotton 14 and the piezoelectric ceramic 16 due to vibration of the piezoelectric ceramic 16 in operation of the atomizer 1.

(27) The piezoelectric ceramic 16 of the present embodiment is similar to the ultrasonic atomizing sheet in Embodiment 1, and is driven by an electric conductor to form an ultrasonic atomizing sheet to atomize the tobacco tar. The piezoelectric ceramic 16 of the present invention is obliquely arranged at an inclination angle of A. Preferably, 0<A<90°, and more preferably, 50°≤A≤75°. Within this angle range, two ends of the atomization cotton are directly immersed in a tobacco tar cavity to realize a tar guide function. When the atomizer is in operation, sufficient tar supply is ensured. When the atomizer is not in operation, excess tobacco tar on the piezoelectric ceramic is returned to the tobacco tar cavity through the atomization cotton at the lower end of the inclined portion, so that the tobacco tar on the atomization cotton is saturated, the surface of the piezoelectric ceramic does not accumulate the tobacco tar or is not soaked in the tobacco tar, and a sufficient amount of tobacco tar is supplied for atomization.

(28) An air outlet 39 communicated with a suction passage and an air inlet 40 communicated with the atomization surface of the atomization cotton 14 are formed in the center of the silica gel seat 13 of the present embodiment, and the air inlet 40 is communicated with the air outlet 39 through a ventilation groove 42. Thus, the silica gel seat 13 is provided with an air inlet 40, and the airflow enters the atomization surface of the piezoelectric ceramic 16 through the air inlet 40, and then the smoke is discharged from the air outlet of the silica gel seat 40.

(29) An atomizing seat 37 is mounted in the housing 18. The atomizing seat 37 is provided with a piezoelectric ceramic mounting cavity 34 for placing the piezoelectric ceramic 16. The atomization cotton 14 passes through the gap between the atomizing seat 37 and the silica gel seat 13, and the two ends of the atomization cotton 14 are in contact with the tobacco tar in the tobacco tar cavity, so that a sufficient amount of tobacco tar can be supplied to the ultrasonic atomizing sheet. The atomizing seat 37 is provided with an inclined cavity for placing the piezoelectric ceramic 16 at an inclination angle of A, 0°<A<90°, preferably 50°≤A≤75°. Within this angle range, the two ends of the atomization cotton are directly immersed in the tobacco tar cavity to realize a tobacco tar guide function. When the atomizer is in operation, sufficient tobacco tar supply is ensured. When the atomizer is not in operation, excess tobacco tar on the piezoelectric ceramic is returned to the tobacco tar cavity through the atomization cotton at the lower end of the inclined portion, thus preventing the piezoelectric ceramic from being soaked in the tobacco tar.

(30) The atomization cotton 14 of the present invention is in contact with a part of the surface of the piezoelectric ceramic to improve the operating rate of the piezoelectric ceramic, thereby improving the user experience. The top of the atomization cotton 14 is pressed by a support pillar 41 arranged at the lower part of the silica gel seat 13, thereby preventing the atomization cotton 14 from being separated from the piezoelectric ceramic 16 to affect the atomization effect. The support pillar 41 abuts against the atomization cotton 14. When the piezoelectric ceramic 16 is in operation, the atomization cotton 14 is kept in contact with the piezoelectric ceramic 16, thereby increasing the atomization effect, and preventing the atomization cotton from being sucked up by smoking force to separate from the piezoelectric ceramic.

(31) An atomizer, as shown in FIGS. 6 and 7, includes a suction nozzle 11 and a housing 18. A tobacco tar cavity is formed in the housing 18. The tobacco tar in the tobacco tar cavity enters the atomization cotton 14, the atomization cotton 14 delivers the tobacco tar to the atomization surface of the piezoelectric ceramic being as an ultrasonic atomizing sheet for atomization, and the atomized smoke is sucked by a smoker through the air outflow passage of the suction nozzle.

(32) The external thread of the housing 18 is connected with the suction nozzle 11. The suction nozzle 11 of the present invention can be removed for cleaning.

(33) A side wall of the housing 18 is provided with an air inlet slot 30 which communicates with an air inlet of the silica gel seat 13.

(34) Since the piezoelectric ceramic 14 of the present invention is placed obliquely, the smoke ejected when the piezoelectric ceramic 14 atomizes the tobacco tar is jetted onto the inner wall of the air outlet 39, so that the smoke droplets formed by the large-particle smoke drop onto the atomization cotton 14 along the inner wall and are recovered for re-atomization, and the smoke jetted from the piezoelectric ceramic 14 is prevented from directly impacting the user's mouth to produce bad experience such as tongue spiciness.

(35) In addition, the two ends of the atomization cotton 14 of the present invention directly stretch into the tobacco tar cavity to directly contact the tobacco tar, so that the tobacco tar guide speed is higher when atomizing, and the atomization effect is better. At the same time, the piezoelectric ceramic 16 is placed obliquely, so the tobacco tar is not accumulated, and the atomization starting rate is improved.

(36) An electronic cigarette, as shown in FIG. 5, includes the above atomizer 1 and a battery assembly 2, wherein the atomizer 1 is magnetically connected with the battery assembly 2 to facilitate disassembly.

(37) The battery assembly of the present invention includes a battery cover 26, a large bracket 25, and a battery 27. A heat insulation space 29 is formed in the large bracket 25 to prevent the heat generated by the battery assembly 2 from being transferred to the battery cover 26 to scald hands when the electronic cigarette is in operation.

(38) An upper fixing cover 19 is arranged at the bottom of the housing 18, a lower fixing cover 21 is arranged at the top of the battery cover 26, an upper electrode 20 is mounted on the upper fixing cover 19, a lower electrode 22 is mounted on the lower fixing cover 21, and the upper electrode 20 is electrically connected with the lower electrode 22. A key 23 is mounted on a side face of the battery cover 26, a PCB 24 is arranged inside the key 23, the battery 27 is electrically connected with the PCB 24, and the PCB 24 is in contact with the lower electrode 22 when the PCB 24 is pressed by the key 23, so that the battery 27 supplies power to the piezoelectric ceramic being as an ultrasonic atomizing sheet for ultrasonic atomization.

(39) The present embodiment differs from Embodiment 1 in that:

(40) 1. The atomization cotton 14 is in direct contact with the tobacco tar, so that when the atomizer 1 is in operation, the tobacco tar guide rate is higher and the atomization effect is better.

(41) 2. The piezoelectric ceramic 16 is arranged in the tobacco tar cavity, and the piezoelectric ceramic 16 is placed obliquely. When the piezoelectric ceramic 16 is in operation, the smoke formed by atomization of the tobacco tar is jetted to the inner wall of the air outlet 39, the inner wall collects and condenses large-particle smoke into smoke droplets, and the smoke droplets drop onto the atomization cotton 14 along the inner wall and are re-atomized. During this process, small-particle smoke is sucked by the user, thus prevent the large-particle smoke from being sucked to affect the taste of the smoke.

(42) 3. The support pillar 41 is arranged on the atomizing seat 37, and abuts against the atomization cotton 14 to prevent the atomization cotton 14 from being separated from the piezoelectric ceramic 16 to affect the atomization effect.

(43) The contents illustrated by the above embodiments should be understood as these embodiments are merely used for illustrating the present invention more clearly, rather than limiting the scope of the present invention. Various equivalent modifications made to the present invention by those skilled in the art after reading the present invention all fall within the scope defined by the appended claims of the present application.
