DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS



[0017] The vaporizer of the disclosure may be connected with a battery part to constitute an electronic cigarette. For convenience of description, the terms, such as "upper", "lower", "upper portion", "lower portion", "upper end", "lower end", "upper surface", "lower surface", "upwards", "downwards", "transverse", and "vertical" as used herein for illustrating various components, refer to position and orientation relationships when the base of the vaporizer is vertically disposed to face upwards, as shown in FIG.2.

Embodiments of the disclosure



[0018] The disclosure will be further explained in detail with reference to particular embodiments.

Embodiments



[0019] Referring to FIG. 1, the vaporizer of the disclosure is provided with a housing 1, and a vaporizing support 2, a vaporizing core 3, a vaporizing base 4, a vaporizer base 5, and a bottom cover 6 are disposed in the housing 1. Herein, the vaporizing core 3 comprises a porous liquid guiding element and a heating element (not shown in the drawings) disposed on the surface of the porous liquid guiding element. A chamber defined in an upper portion of the housing 1 serves as a liquid storage chamber for storing the vaporizing liquid. The porous liquid guiding element can absorb the vaporizing liquid from the liquid storage chamber. When the vaporizer operates, the heating element is energized to generate heat, such that the vaporizing liquid on the surface of the porous liquid guiding element can be heated and atomized to produce aerosol.

[0020] Referring to FIGs.2-8, the vaporizer base 5 is provided with a base body 51, a circuit board 52, a chip 53, signal electrodes 54, and two electrode columns 55. Herein, the chip 53, the signal electrodes 54, and the electrode columns 55 are mounted on the circuit board 52. The circuit board 52 and the chip 53 are embedded within the base body 51. The bottom portions of the signal electrodes 54 and the electrode columns 55 are flat and exposed at the bottom portion of the base body 51. Thus, when the vaporizer is connected with the power supply part, the power electrodes and signal electrodes in the power supply part are allowed to abut against and connect with the electrode columns 55 and the signal electrodes 54, respectively, to provide power supply and control signal sources. The upper portions of the electrode columns 55 respectively extend upwards above the base body 51 and are used to make contact and electrical connection with the positive and negative terminals of the heating element. The two electrode columns include a positive electrode column and a negative electrode column, which have unfixed and interchangeable positive and negative polarities such that either of the two electrode columns can be connected with the positive or negative terminal of the power supply part. In such a case, during connection of the vaporizer and the power supply part, the vaporizer can be connected to the power supply part regardless of its front and rear orientations. Thus, it is easy to use. The chip according to the embodiment of the disclosure may be an encrypted chip which can be used for anti-counterfeit of the vaporizer.

[0021] In other embodiments, the vaporizer base 5 may not include the signal electrodes 54. Instead, the signal electrodes 54 may be integrated into one of the electrode columns 55. Furthermore, the chip 53 may not be an encrypted chip, but instead it may be a control chip for other purposes. In other embodiments, the chip 53 may also be an unpackaged wafer.

[0022] In the embodiment of the disclosure, the chip 53 may be fixed to the circuit board 52 through a bonding process, and a layer of bonding glue 531 may be coated on the chip 53 to facilitate fixing of the chip 53 to the circuit board 52.

[0023] Herein, the vaporizer base 5 may be integrally formed by fixing the chip 53, the signal electrodes 54, and the electrode columns 55 onto the circuit board 52, and then placing the circuit board 52 into a mold to be injection-molded together with the base body 51.

[0024] An air inlet through hole 56 may be provided at the bottom portion of the base body 51. The air inlet through hole 56 may extend through both the base body 51 and the circuit board 52, to allow outside air to enter the vaporizer.

[0025] On both sides of the base body 51, the plungers 57 may be provided to block the liquid filling holes provided inside the vaporizer. The liquid filling holes can facilitate the injection of the vaporizing liquid into the vaporizer of the disclosure during manufacturing and production, and allow the liquid storage chamber of the vaporizer to be filled up with the vaporizing liquid. After the filling of the vaporizing liquid into the liquid storage chamber of the vaporizer, the plungers 57 may plug the liquid filling holes to prevent liquid leakage during mounting of the vaporizer base 5.

[0026] The roots of the electrode columns 55 may extend through the circuit board 52. On the bottom side of the circuit board 52, each of the electrode columns 55 may be provided with a thrust flange 551, which function to retain the position when the bottom end of respective one of the electrode columns 52 is subjected to an upward push force. On the upper side of the circuit board 52, each of the electrode columns 55 may be provided with an annular groove 552. The annular grooves 552 can be embedded into the material of the base body during integral injection molding of the circuit board 52 and the base body 51, thereby enabling the roots of the electrode columns 55 to tightly engage and connect with the base body 51 and thus preventing the electrode columns 55 from loosening during use.

[0027] Referring to FIGs.7 and 9, the chip 53, namely the chip U in the drawings, may be provided with three leads. Herein, the first lead u1 may be electrically connected with the signal electrodes 54, i.e. the signal terminals RSD; the second lead u2 may be electrically connected with one terminal of the capacitor C1; the other terminal of the capacitor C1 may be connected with one of the electrode columns 55, i.e., the negative power terminal - as shown in the drawings, and the other terminal of the capacitor C1 may be connected with the third lead u3 of the chip U as well. In the drawings, the positive power terminal + may be connected with the other one of the electrode columns 55. The two electrode columns 55 are interchangeable in connecting either the positive or negative power supply. The chip 53 of the disclosure can get power through the signal electrodes 54.

[0028] According to the vaporizer base 5 with a built-in chip of the disclosure, the vaporizer base 5 is formed by fixedly mounting the chip 53 onto the circuit board 52 and then integral injection molding them with the base body 51, such that the chip 53 and the circuit board 52 which are embedded within the interior of vaporizer base 5 are not exposed. In such a case, the appearance of the vaporizer base 5 can be improved. In the meantime, it prevents long periods of exposure of the chip 53 or the circuit board 52 with the vaporizing liquid or condensed liquid dropped in the vaporizer and the aerosol produced by vaporization, prevents the chip 53, the circuit board 52, and other circuit elements disposed on the circuit board 52 from malfunction due to contamination or corrosion by the vaporizing liquid or condensed liquid, and prevents functional damage of the chip 53, the circuit board 52, or other circuit elements disposed on the circuit board 52. In the meantime, it prevents users from inhaling harmful substances contained in the chip 53 and circuit board 52 and volatilized in the aerosol after long periods of exposure with the aerosol produced by vaporization, to protect health.
