Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to an atomizer and an electronic cigarette using the atomizer. Background Art

[0002] An electronic cigarette is an electronic product that simulates a cigarette. It mainly includes an electronic cigarette body and an atomizer. The atomizer can atomize the tobacco material so that the user can inhale a flavor similar to that of a cigarette. A heating element is provided in the atomizer to heat the cigarette pot. Dry tobacco or tobacco paste and other tobacco materials are placed in the cigarette pot. Generally, the heating element is directly in contact with the bottom surface of the cigarette pot, and the heating element is in an exposed state. During the heating process, the fluid overflowing from the cigarette pot will drip onto the surface of the heating element and cause the heating element to cool suddenly, causing the heating element to rupture or rapidly age; or, the steam generated from the cigarette pot will adhere to the surface of the heating element after condensation to form residues. These residues will affect the heating rate and heat transfer capacity of the heating element, and the residues will stick the heating element to the cigarette pot. If the residues are not cleaned up in time, it is easy to make it difficult to separate the heating element from the cigarette pot, and it is easy to cause damage to the heating element when replacing the cigarette pot. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art, that is, to provide an atomizer that can avoid the attachment of residues on the heating element and prolong the service life of the heating element; a second purpose is to provide an electronic cigarette using the above-mentioned atomizer, which has stable performance and a long service life.

[0006] Beneficial effects: The atomizer of the above structure utilizes a heat transfer cover to cover the heating element therein, thereby preventing the fluid overflowing from the cigarette pot from dripping onto the surface of the heating element and causing the heating element to rupture or rapidly age; or preventing the steam generated in the cigarette pot from adhering to the surface of the heating element after condensation and forming residues that affect the heating rate and heat transfer capacity of the heating element, and will not cause sticking between the cigarette pot and the heating element, thus avoiding damage to the heating element when disassembling the cigarette pot, thereby improving the working stability of the atomizer and extending the service life of the heating element.

[0007] In the above technical solution, further, a graphene sheet is provided between the heating element and the heat transfer cover, and the graphene sheet can quickly and evenly transfer the heat generated by the heating element to the heat transfer cover, and then transfer the heat from the heat transfer cover to the cigarette pot.

[0008] In the above technical solution, further, the heating element is a heating sheet, the lower part of the heating sheet is connected to a terminal assembly extending downward, the terminal assembly is electrically connected to an atomizing core electrode, and the graphene sheet is respectively against the upper surface of the heating sheet and the inner surface of the heat transfer cover facing the heating sheet, that is, the graphene sheet is clamped between the heating sheet and the heat transfer cover, and the heating sheet, the graphene sheet and the heat transfer cover are in planar contact with each other, which can increase the contact area and improve the heat conduction efficiency.

[0009] In the above technical solution, further, the shell assembly includes a base, an outer cover, a vent pipe joint and a rotating nut. The vent pipe joint is installed on the upper part of the outer cover and abuts against the surface of the cigarette pot. The vent pipe joint is used to fix the cigarette pot. The rotating nut is installed on the upper part of the outer cover and is fixed on the outside of the vent pipe joint. Preferably, the vent pipe joint and the rotating nut are riveted and fixed, the rotating nut is screwed on the upper part of the outer cover, the base is installed on the lower part of the outer cover, the atomizer core electrode is located in the base, and the base and the atomizer core electrode are tightly fixed by an insulating member. The base and the atomizer core electrode are both provided with a smoke channel connected to the cavity.

[0010] In the above technical solution, further, in order to ensure the effect of heat conduction, a supporting portion for supporting the heating plate is provided on the upper part of the base. The supporting portion presses the heating plate upward so that the graphene sheet fits onto the inner surface of the heat transfer cover. The base is provided with a number of through holes for the terminal assembly to pass downward.

[0011] In some technical solutions of the present invention, the heat transfer cover is buckled and connected to the base, so as to facilitate the disassembly and assembly of the heat transfer cover and further facilitate the replacement of the heating element.

[0012] In the above technical solution, further, a buckle portion is provided on one of the inner wall surface of the heat transfer cover and the base, and a clamping groove matched with the buckle portion is provided on the other.

[0013] Of course, in some other technical solutions, the heat transfer cover can also be fixed to the base by riveting to ensure the stability of the connection between the two.

[0014] In any of the above technical solutions, the outer bottom surface of the cigarette pot is provided with a receiving groove matching the heat transfer cover, and the receiving groove can prevent the heat transfer cover from being displaced greatly relative to the cigarette pot, thereby affecting the heat conduction efficiency between the two.

[0015] In some technical solutions of the present invention, a sink is provided on the bottom surface of the base, a first limiter located in the sink is provided on the insulating member, and a second limiter abutting against the bottom surface of the insulating member is provided on the atomizer core electrode. When it is necessary to detach the terminal assembly on the heating sheet from the atomizer core electrode, the first limiter can prevent the relative displacement between the insulating member and the base, and the second limiter can prevent the relative displacement between the atomizer core electrode and the insulating member, thereby avoiding poor electrical contact when the terminal assembly is combined with the atomizer core electrode again.

The heat transfer performance of the heating element of the electronic cigarette is stable and the service life is long. BRIEF DESCRIPTION OF THE DRAWINGS
