Field of Invention

[0001] The present invention belongs to an atomizer and an electronic cigarette.Background of Invention

[0002] CN 203 662 023 U discloses an ultrasonic atomizing device. CN 205 432 145 U discloses an ultrasonic atomizer and electronic cigarette. CN 104 382 238 A discloses an electromagnetic induction smoke generating device and an electronic cigarette with the device. CN 105 795 527 A discloses an electronic cigarette atomizer and an electronic cigarette. CN 105 795 526 A discloses an electronic cigarette atomizer.

[0003] In an existing ultrasonic high-frequency atomizing electronic cigarette, the surface of an ultrasonic high-frequency atomizing piece is covered with a piece of tobacco tar guide cotton, and the contact between the tobacco tar guide cotton and the atomizing piece is surface contact.

[0004] For the atomizing piece made by piezoelectric ceramic, after the piezoelectric ceramic piece is energized, it does not immediately oscillate to atomize the tobacco tar guide cotton. Instead, it is energized at first to generate heat, and when the heat reaches a certain level, the piezoelectric ceramic piece oscillates to atomize the tobacco tar guide cotton. After the tobacco tar guide cotton is covered on the surface of the piezoelectric ceramic piece and the piezoelectric ceramic piece is energized, the piezoelectric ceramic piece generates heat, but since the tobacco tar guide cotton itself absorbs the heat and the contact surface between the tobacco tar guide cotton and the piezoelectric ceramic piece is large, a part of the heat is transferred to the tobacco tar guide cotton, such that the piezoelectric ceramic piece takes a long time to produce the heat needed to achieve its oscillation. In this way, the duration from the time when piezoelectric ceramic piece starts working to the start of oscillation atomization is too long, and the waiting time of a user to inhale the first mouth of smoke is long, so that the experience is poor.

[0005] Moreover, since the contact between the tobacco tar guide cotton and the atomizing piece is surface contact the phenomenon that the tobacco tar guide cotton is difficult to atomize after being supersaturated due to too much tobacco tar absorption is often generated.Summary of Invention

[0006] In view of the above problems, the present disclosure aims at providing an atomizer with a high smoke production speed and a good atomizing effect, and an electronic cigarette.

[0007] According to the present invention, an atomizer with the features of claim 1 is provided.

[0008] According to the present teaching, there is provided an atomizer, including an atomizer body, and an atomizing core and a tobacco tar cavity both arranged in the atomizer body, wherein the atomizing core includes an atomizing piece and a strip-shaped tobacco tar guide body which guides tobacco tar in the tobacco tar cavity to an atomizing surface of the atomizing piece; and the strip-shaped tobacco tar guide body spreads across the atomizing piece and props against the atomizing surface of the atomizing piece, and the area of a contact surface of the strip-shaped tobacco tar guide body and the atomizing piece is less than the area of the atomizing surface of the atomizing piece.

[0009] Accordingly, the area of the contact surface of the strip-shaped tobacco tar guide body and the atomizing piece is less than the area of the atomizing surface of the atomizing piece, which is similar to the situation of line contact, so that the strip-shaped tobacco tar guide body scarcely absorbs the heat generated by the atomizing piece, the atomizing piece can quickly generate heat and start oscillating, and thus the first mouth of smoke is quickly atomized. In the solution, the time from the start of working of the atomizing piece to the start of oscillation atomization is shortened, such that smoke is released quicker.

[0010] Specifically, the atomizer body includes a shell, an air inlet, a suction nozzle installed at the top of the shell, and a connecting electrode installed at the bottom of the shell, and the tobacco tar cavity and the atomizing core are arranged in the shell; an air inlet passage communicated with the air inlet is arranged in the shell, and the air inlet passage leads to the atomizing surface of the atomizing piece; and an air outlet passage communicated with the suction nozzle is arranged in the shell; and the atomizing piece is electrically connected with the connecting electrode.

[0011] Further, the atomizing core further includes a fixing sleeve arranged to lean against the inner wall of the shell and located below the tobacco tar cavity, and a first hollow cavity is arranged in the fixing sleeve; and an atomizing piece fixing seat is arranged at the lower part of the first hollow cavity, and the atomizing piece is installed on the atomizing piece fixing seat; and the atomizing surface of the atomizing piece props against the strip-shaped tobacco tar guide body, and a non-atomizing surface of the atomizing piece is electrically connected with the connecting electrode.

[0012] The air inlet is located at the bottom of the connecting electrode, the air inlet passage is a second hollow cavity arranged in the connecting electrode, and the second hollow cavity is communicated with the first hollow cavity; and the air outlet passage includes an air pipe, the top of the air pipe is communicated with the suction nozzle, a hollow sealing cover is arranged at the lower end of the air pipe, and the sealing cover is connected with the top of the first hollow cavity and seals the top of the first hollow cavity.

[0013] After the sealing cover is connected with the first hollow cavity of the fixing sleeve, an isolation surface is formed by the seal, and the tobacco tar cavity is located above an upper surface of the sealing cover.

[0014] According to the present invention, fixing grooves are symmetrically formed in the outer wall of the fixing sleeve, via holes are laterally formed in the lower ends of the fixing grooves in the outer wall of the fixing sleeve, the strip-shaped tobacco tar guide body penetrates through the via holes, the middle segment of the strip-shaped tobacco tar guide body props against the atomizing surface of the atomizing piece, and the remaining segments of both ends of the strip-shaped tobacco tar guide body are clamped in the fixing grooves; and the both ends of the strip-shaped tobacco tar guide body stretch from the fixing grooves and are inserted into the tobacco tar cavity.

[0015] Accordingly, the tobacco tar in the tobacco tar cavity is directly guided by the strip-shaped tobacco tar guide body into the atomizing piece.

[0016] In another specific embodiment, not forming part of the claimed invention, a tobacco tar inlet groove is formed in the edge of the sealing cover, annular tobacco tar guide cotton is arranged to lean against the inner wall of the fixing sleeve, and the tobacco tar guide cotton props against the tobacco tar inlet groove; and a plurality of strip-shaped tobacco tar guide bodies arranged at intervals spread across the atomizing piece, and both ends of each strip-shaped tobacco tar guide body prop against the tobacco tar guide cotton.

[0017] Accordingly, the strip-shaped tobacco tar guide body is not directly in contact with the tobacco tar cavity, but the tobacco tar is indirectly transferred to the strip-shaped tobacco tar guide body through the tobacco tar guide cotton and then enters the atomizing piece, and the process effectively slows the tobacco tar leakage phenomenon resulting from that the tobacco tar is directly absorbed by the strip-shaped tobacco tar guide body.

[0018] In order to facilitate the fixing of the strip-shaped tobacco tar guide body, a fixing bayonet is formed in the atomizing piece fixing seat, and the corner of the strip-shaped tobacco tar guide body is clamped and fixed in the fixing bayonet.

[0019] Preferably, the strip-shaped tobacco tar guide body is a glass fiber thread having a diameter of 0.3 mm to 5 mm. Since the diameter of the glass fiber thread is relatively small, the glass fiber thread absorbs less tobacco tar when the atomizing piece is not working, therefore the phenomenon can be avoided that little smoke is generated or the smoke is produced slowly because the surface of the atomizing piece is immersed by too much tobacco tar.

[0020] Preferably, the area of the contact surface of the strip-shaped tobacco tar guide body and the atomizing piece accounts for 5% to 25% of the area of the atomizing surface of the atomizing piece.

[0021] Preferably, the atomizing piece is a solid piezoelectric ceramic piece.

[0022] Correspondingly, the present teachings further provide an electronic cigarette, including an external power source, wherein the electronic cigarette further includes the atomizer in the above solution, and the external power source is connected with the connecting electrode of the atomizer.

[0023] The present teachings have the following significant effects: 1. The area of the contact surface of the strip-shaped tobacco tar guide body and the atomizing piece is less than the area of the atomizing surface of the atomizing piece, which is similar to the structural form of line contact, so that the strip-shaped tobacco tar guide body scarcely absorbs the heat generated by the atomizing piece, and the atomizing piece can quickly generate heat and start oscillating, and thus the first mouth of smoke is produced by quick atomization. In the solution, the time from the start of working of the atomizing piece to the start of oscillation atomization is shortened, such that smoke is released quicker, and the user experience is better. 2. Due to the small contact area, the tobacco tar transferred by the strip-shaped tobacco tar guide body is not excessive, so that the phenomenon that the tobacco tar guide body is difficult to atomize after being supersaturated due to too much tobacco tar absorption is not generated.
