Technical Field

[0001] The utility model relates to the technical field of electronic cigarette components, and more specifically, to an electronic cigarette atomizer. Background Art

[0002] An electronic cigarette generally includes a cigarette rod and a cartridge atomizer. For example, the Chinese patent with the publication number CN202320317437.2 is a common structure of an electronic cigarette. When the cartridge atomizer is not in use, the e-liquid in the oil storage cavity of the atomizer easily penetrates through the oil guiding hole, which is likely to cause e-liquid leakage. Therefore, in view of this situation, the utility model ingeniously proposes an electronic cigarette atomizer to solve the deficiencies in the above technical background. Content of the Utility Model

[0003] The purpose of the utility model is to solve the problem that the existing cartridge atomizer is prone to e-liquid leakage during the idle period.

Detailed implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Such as Figures 1 to 4As shown: An electronic cigarette atomizer includes an upper housing 1. A smoking port 101 is provided in the upper housing 1. A lower housing 2 is fixedly connected below the upper housing 1. A base 7 is fixedly embedded in the lower housing 2. A sealing rubber ring 6 is provided between the upper part of the base 7 and the lower housing 2. The sealing rubber ring 6 is used to seal the connection between the base 7 and the lower housing 2. A atomization core is provided in the base 7. The atomization core includes an outer tube 9. An outer oil guiding port 901 is provided on the side of the outer tube 9. The outer tube 9, the upper housing 1, the lower housing 2 and the sealing rubber ring 6 are combined to form a closed oil storage chamber 102 inside. The oil storage chamber 102 is used to store e-liquid. And the e-liquid in the oil storage chamber 102 enters the atomization core through the outer oil guiding port 901 and is heated and atomized. Arc plates 15 are provided on both sides of the outer tube 9. The arc plates 15 are arranged corresponding to the contour of the outer tube 9. And an elastic block 16 is fixedly connected between the arc plates 15 and the outer tube 9. The arc plates 15 and the outer tube 9 are spaced apart by the elastic block 16. When the arc plates 15 move under the action of an external force, the elastic block 16 will be squeezed and deformed, and the arc plates 15 will contact the wall of the outer tube 9, thereby closing the outer oil guiding port 901 on the outer tube 9, thus avoiding the problem of e-liquid leakage when the electronic cigarette is idle. Two through holes are provided on both sides of the upper housing 1. A first cover 3 and a second cover 4 are respectively inserted into the two through holes to close them. The outer sides of the first cover 3 and the second cover 4 are connected and fixed. When the e-liquid is exhausted, the second cover 4 can be opened to add e-liquid into the oil storage chamber 102. At this time, the first cover 3 is still inserted on the upper housing 1. After the second cover 4 is pulled out from the through hole, it can rotate around the first cover 3, thus avoiding the first cover 3 and the second cover 4 being completely separated from the upper housing 1, and further reducing the risk of loss of the first cover 3 and the second cover 4. The second cover 4 can be made of an elastic material. And a deformation cavity 402 is provided in the second cover 4. A push rod 401 is fixedly connected to the part of the second cover 4 located inside the oil storage chamber 102. The other end of the push rod 401 abuts against the outer side of the corresponding arc plate 15. A plug post 501 is also inserted into the second cover 4. After the plug post 501 is completely inserted into the second cover 4, it drives the deformation cavity 402 to deform, and then drives the push rod 401 on the second cover 4 to move, so that the push rod 401 pushes the arc plate 15 to move, and then the arc plate 15 closes the outer oil guiding port 901, thus avoiding the e-liquid from leaking when the electronic cigarette is idle.

[0020] Preferably, as Figures 3 to 4 shown, a concave limiting port 403 is provided in the second cover 4. A plurality of limiting rings 502 are provided on the side of the plug post 501. The limiting rings 502 are arranged corresponding to the limiting port 403. Through the cooperative arrangement of the limiting rings 502 and the limiting port 403, the insertion depth of the plug post 501 can be limited at different positions. When the plug post 501 is inserted to half of its depth, the deformation cavity 402 does not produce obvious deformation, so that the push rod 401 does not drive the arc plate 15 to move, and thus the e-liquid can normally enter the outer tube 9 from the outer oil guiding port 901.

[0021] Among them, as Figures 1 to 4As shown in the figure, concave openings 103 recessed inward are provided on both sides of the upper housing 1. The first cover 3 and the second cover 4 are both arranged in the concave openings 103. A fixing piece 5 is fixedly connected to the outer side of the insertion post 501. A limiting portion 104 is also provided in the concave opening 103. The limiting portion 104 is only arranged at a position close to the first cover 3. The upper side of the fixing piece 5 can be inserted between the limiting portion 104 and the concave opening 103. Through the extrusion of the limiting portion 104, the fixing piece 5 is driven to extrude the first cover 3, so that the first cover 3 seals the through opening on the housing more tightly, preventing oil leakage. At the same time, when the insertion post 501 is inserted into the second cover 4, it can also cause the second cover 4 to expand and deform, so that the second cover 4 better seals the through opening on the upper housing 1.

[0022] Preferably, the first cover 3 can be made of a transparent material. After the fixing piece 5 is moved out of the position of the limiting portion 104, the amount of e-liquid in the e-liquid tank 102 can be observed through the first cover 3 to facilitate the timely addition of e-liquid.

[0023] Among them, as Figures 1 to 4 shown, the atomizing core further includes an inner tube 14. The inner tube 14 is fixedly connected to the center above the base 7. An outer tube 9 is sleeved outside the inner tube 14. The upper side of the outer tube 9 is inserted into the smoking port 101 and communicated with it. A sealing ring 10 is provided between the smoking port 101 and the outer tube 9 for sealing. An inner oil guiding port 141 is provided on the side of the inner tube 14. An outer oil guiding member 18 is provided between the outer tube 9 and the inner tube 14. A heating core 8 is arranged inside the inner tube 14, and an inner oil guiding member 17 is sleeved outside the heating core 8. Two wires 11 are also fixedly connected below the heating core 8. Two electrodes 12 are fixedly connected to the bottom of the base 7. The two electrodes 12 are arranged corresponding to the two wires 11. The electrodes 12 are used to conduct electricity with the battery in the cigarette rod. A ventilation hole 701 is also provided at the bottom of the base 7. The ventilation hole 701 is used to circulate air flow with the cigarette rod. By providing the inner and outer double-layer oil guiding members, the atomization effect of the e-liquid is better.

[0024] Among them, as Figure 1 shown, clamping openings 201 are provided on both the front and rear sides in the lower housing 2. The clamping openings 201 are used to facilitate the clamping connection with the buckle in the cigarette rod.

[0025] Among them, as Figure 3 shown, a magnet 13 is also fixedly connected to the bottom of the base 7. The magnet 13 is used to adsorb the iron block on the cigarette rod, making the connection between the cigarette rod and the lower housing 2 more stable.
