Description

Atomizer, battery assembly and electronic cigarette Technical Field

The present invention relates to the technical field of electronic cigarettes, and in particular to an atomizer, a battery assembly and an electronic cigarette.

Background technique

In the prior art, most of the replaceable heating core atomizers are adsorbed by magnets. Two atomizer electrodes are provided on one end face of the electronic cigarette atomizer, and a receiving cavity is provided in the cigarette rod. Two cigarette rod electrodes are provided in the receiving cavity. When the atomizer is inserted into the receiving cavity of the cigarette rod, the atomizer electrode and the cigarette rod electrode are docked with each other to achieve electrical connection. However, this method has high requirements for the accuracy of electrode setting, and requires continuous debugging during the production process.

It should be noted that the specification of this application records a large number of technical features, which are distributed in various technical solutions. If all possible combinations of technical features (i.e. technical solutions) of this application are to be listed, Otherwise, the specification will be too lengthy. In order to avoid this problem, the various technical features invented in the above invention content of this application, the various technical features invented in the various implementation modes and examples below, and the various technical features invented in the drawings can be freely combined with each other to form various new technical solutions (these technical solutions are deemed to have been recorded in this specification), unless such combination of technical features is technically infeasible. For example, in one example, feature A+B+C is invented, and in another example, feature A+B+D+E is invented. Features C and D are equivalent technical means that play the same role. Technically, only one of them can be used, and it is impossible to use them at the same time. Feature E can be technically combined with feature C. Then the solution of A+B+C+D should not be deemed to have been recorded because it is technically infeasible, while the solution of A+B+C+E should be deemed to have been recorded.

Please refer to Figures 1, 2, 3, 4 and 5. The present application provides an electronic cigarette 10, including an atomizer A and a battery assembly B. The atomizer A includes a heating core 20 for heating to generate smoke and a first electrical connection assembly 110 for powering on. The battery assembly B includes a battery 141 and a second electrical connection assembly 120. The second electrical connection assembly 120 is electrically connected to the battery 141 and the first electrical connection assembly 110, respectively.

The first electrical connection component 110 and the second electrical connection component 120 are pluggably connected to each other; the atomizer A and the battery component B are detachably connected via the first electrical connection component 110 and the second electrical connection component 120 .

The inter-pluggable connection specifically means that when the first electrical connection component 110 can be pushed toward the second electrical connection component 120 along the central axis direction of the second electrical connection component 120, the first electrical connection component 110 and the second electrical connection component 120 engage with each other, so that at least when not subjected to external force, the first electrical connection component 110 is mechanically fixed relative to the second electrical connection component 120. It should be understood that the above operation can also be achieved by the reverse movement of the second electrical connection component 120 along the first electrical connection component.

The electronic cigarette further comprises: a connecting assembly, the connecting assembly comprising a first connecting member 51 arranged on the first electrical connecting assembly 110, a second connecting member 52 arranged on the second electrical connecting assembly 120, the connecting assembly being used to connect the atomizer A with the battery assembly B. The detachable connection, the connecting piece includes but is not limited to a magnetic structure or a snap-on structure.

When the first electrical connection component 110 and the second electrical connection component 120 are plug-connected, the first connection member 51 provided on the first electrical connection component 110 and the second connection member 52 provided on the second electrical connection component 120 are detachably connected.

At the same time, the electrodes of the heating core 20 are applied to the first electrical connection component 110, and the electrodes of the battery 141 are applied to the second electrical connection component 120. After the first electrical connection component 110 and the second electrical connection component 120 are plugged in and out of each other, it is ensured that when the first electrical connection component 110 is installed on the second electrical connection component 120, the heating core 20 and the battery component 141 are firmly and reliably electrically connected;

Compared with the traditional end-face butt contact method, it can withstand relatively higher loads during use, such as vibration in plug-in connections. When the end faces are butted, the magnets are misaligned due to vibration, and the magnetic force is reduced, resulting in separation from the relative plug-in connection.

Specifically, after the atomizer A is docked with the battery assembly B, the first electrical connection assembly 110 and the second electrical connection assembly 120 are plugged in and out of each other, so that the battery 141 in the battery assembly B is electrically connected to the heating core 20 in the atomizer A, thereby realizing the heating and atomization effect of the heating core 20 on the e-liquid, so as to facilitate the user to inhale the atomized e-liquid.

Compared with the prior art in which the atomizer A with replaceable heating core 20 is mostly adsorbed by magnets, the atomizer A of the electronic cigarette 10 is provided with two atomizer electrodes on one end face, and a accommodating cavity is provided in the battery assembly, and two battery assembly electrodes are provided in the accommodating cavity. When the atomizer A is inserted into the accommodating cavity of the battery assembly, the end face of the atomizer electrode and the end face of the battery assembly electrode are butted against each other to achieve electrical connection. In comparison, the present application improves the stability of the electrode contact by abutting the side wall surfaces against each other, while reducing the difficulty of debugging, thereby increasing production efficiency and reducing production costs.

Please refer to Figures 3 and 6. The embodiment of the present application provides an atomizer A, which includes: a first electrical connection component 110, a heating core 20, a mouthpiece component 24, an oil storage bin 21, oil storage cotton 22, a smoke guide tube 25 and a fixing tube 26, etc.

The first electrical connection assembly 110 includes a first annular wall 111 and a second annular wall 112. The second annular wall 112 is sleeved on the outer periphery of the first annular wall 111, and the side walls of the first annular wall 111 and the second annular wall 112 are respectively provided with a first electrode and a second electrode, and the first electrode and the second electrode are respectively electrically connected to the heating core 20. (The first electrode and the second electrode are not marked in the figure due to their various forms)

In some embodiments, the first electrode and the second electrode are respectively linear, sheet-shaped or film-shaped conductors and are respectively disposed on the sidewalls of the first annular wall 111 and the second annular wall 112;

The linear, sheet or film-shaped conductor is correspondingly arranged on the side wall surfaces of the first annular wall 111 and the second annular wall 112. Specifically, the conductor is led out from the atomizer core and arranged on the side wall surfaces of the first annular wall 111 and the second annular wall 112 and is abutted and electrically connected to the battery assembly B;

In some embodiments, the first electrode and the second electrode may be disposed on the inner side and/or the outer side of the first annular wall 111 and the second annular wall 112:

For example, the first electrode is arranged on the inner side of the first annular wall 111, and the second electrode is arranged on the inner side of the second annular wall 112; for example, the first electrode is arranged on the inner side of the first annular wall 111, and the second electrode is arranged on the outer side of the second annular wall 112; for example, the first electrode is arranged on the outer side of the first annular wall 111, and the second electrode is arranged on the inner side of the second annular wall 112; for example, the first electrode is arranged on the outer side of the first annular wall 111, and the second electrode is arranged on the outer side of the second annular wall 112.

Preferably, the first electrode is arranged on the inner side of the first annular wall 111 , and the second electrode is arranged on the outer side of the second annular wall 112 .

It only needs to satisfy the correspondence with the electrodes in battery component B.

The shapes of the first annular wall and the second annular wall are not limited to the circular ring shape shown in the figure, but may also be a square ring shape, a diamond ring shape, an elliptical ring shape, etc.

Please refer to FIG. 7 and FIG. 8. In some embodiments, the first electrical connection component 110 further includes a main body 113. The heating core 20 is located at one end of the main body 113. The other end of the main body 113 protrudes to form the first annular wall 111 and the second annular wall 112. A first wire hole 1131 and a second wire hole 1132 are provided on the top, the first electrode and the second electrode are respectively made of a first conductive wire and a second conductive wire, one end of the first conductive wire and the second conductive wire are respectively electrically connected to the heating core 20, and the other end of the first conductive wire and the second conductive wire pass through the first wire hole 1131 and the second wire hole 1132 respectively.

The widths of the first wire hole 1131 and the second wire hole 1132 are respectively adapted to the diameters of the first conductive wire and the second conductive wire to reduce the leakage of residual smoke oil in the atomizer core to the battery assembly B, thereby avoiding oil leakage.

In the prior art, the wires of the heating core 20 are mostly fixed on an adapter by riveting. Compared with riveting the electrodes on the adapter and then connecting them, the solution disclosed in the present application refers to opening a first wire hole 1131 and a second wire hole 1132 on the main body 113, and the two electrodes of the heating core 20 are respectively passed through the connecting parts and abutted through the exposed electrodes, which not only realizes functionality, but also reduces the welding stage and improves production efficiency.

In some embodiments, a first mounting groove 1133 for positioning the first conductive wire is provided on the side wall surface of the first annular wall 111 and/or a second mounting groove 1134 for positioning the second conductive wire is provided on the side wall surface of the second annular wall 112.

The first mounting groove 1133 and the second mounting groove 1134 are used to guide the positions of the first conductive wire and the second conductive wire to prevent the first conductive wire and the second conductive wire from deviating and avoid the problem of poor contact.

Compared with direct wiring, the installation groove is provided to effectively control the displacement of the wires during the plugging and unplugging process, reducing the risk of poor contact.

In some embodiments, the first conductive line extends from one side of the first annular wall 111 through the end edge of the first annular wall 111 to the other side of the first annular wall 111, and/or the second conductive line extends from one side of the second annular wall 112 through the end edge of the second annular wall 112 to the other side of the second connecting wall.

The first conductive wire and the second conductive wire are bent and arranged to utilize the rigidity of the metal material itself, so that the first conductive wire and the second conductive wire can be connected without setting an additional fixing member. Fixing the two conductive wires to the appropriate position not only reduces the risk of poor contact, but also reduces the number of processes and improves efficiency.

The first conductive wire and the second conductive wire are exposed, which enlarges the contact area. The second electrode assembly only needs to contact any exposed part to achieve electricity.

In some embodiments, the wire diameters of the first conductive wire and the second conductive wire are respectively larger than the groove depths of the first mounting groove 1133 and the second mounting groove 1134, so that when the first electrical connection component 110 and the second electrical connection component 120 are assembled, the wires are submerged in the bottom of the mounting grooves, thereby eliminating the problem of poor contact. Because the conductive wires themselves have a certain elasticity, when the first electrical connection component 110 and the second electrical connection component 120 are clearance-matched, the wires are still stably in contact with the second electrical connection component 120, thereby improving the reliability of the product.

In some other embodiments, either the first annular wall 111 and the second annular wall 112 are made of a conductor;

The first annular wall 111 and the second annular wall 112 are configured as conductors, which are electrically connected to the corresponding first annular wall 111 and the second annular wall 112 by abutting contact, and then transferred to the third annular wall 121 and the fourth annular wall 122 on the battery assembly B through the first annular wall 111 and the second annular wall 112.

In some embodiments, a separation space is formed between the first annular wall 111 and the second annular wall 112 .

In some embodiments, the first annular connecting wall 111 and the second annular connecting wall 112 are coaxially arranged. The coaxial arrangement can be understood as the first annular connecting wall 111 and the second annular connecting wall 112 are arranged around the same central axis.

Similarly, for the convenience of production, they are preferably of the same shape, so that the first annular wall 111 and the second annular wall 112 are coaxially arranged.
