BACKGROUNDThe electronic cigarettes usually heat the e-cigarette liquid by means of a vaporizer, to produce vapor for the user. Existing electronic cigarettes usually each comprise a vaporizer and a battery rod, and the electronic cigarette vaporizer generally comprise a mouthpiece, a liquid storage chamber, a vaporizing member, etc. The cigarette liquid stored in the liquid storage chamber of existing electronic cigarette vaporizer usually has low viscosity. The waxy solid formed by solidification of tobacco tar has high viscosity and can hardly flow at room temperature, and can hardly be vaporized by existing electronic cigarette vaporizers.
In addition, existing electronic cigarettes usually are prefilled with cigarette liquid before delivery. During long-distance transport, leakage of cigarette liquid may occur due to jolt, vibration, and the like, resulting in poor user experience during use.
SUMMARY Technical ProblemAn object of the disclosure is to provide an electronic cigarette vaporizer which overcomes the above shortcomings.
Technical SolutionsThe disclosure provides a technical solution as follow. An electronic cigarette vaporizer comprises an outer tube, a mouthpiece member arranged at one end of the outer tube, a connecting member arranged at the other end of the outer tube, and a vaporizing member arranged inside the outer tube. The mouthpiece member comprises a mouthpiece housing having a mouthpiece end and a connecting end. A vapor passage extending through the mouthpiece end and the connecting end is formed in the center of the mouthpiece housing. The vaporizing member comprises a two-part tube body which is integrally-formed. The two-part tube body consists of a vapor tube located at the upper position and having a smaller diameter, and a vaporizing tube located at the lower position and having a greater diameter. The vapor tube and the vaporizing tube are connected with each other. A storage chamber for storing vapor substrate is formed between an outer wall of the two-part tube body and an inner wall of the outer tube. A tube-shaped vaporizing core for heating and vaporizing the vapor substrate is sleeved inside the vaporizing tube. A wall portion of the vaporizing tube is provided with a substrate through-hole. An upper end of a wall portion of the vapor tube is provided with a vent aperture. During assembly of the mouthpiece member, the connecting end fits tightly between the outer tube and the vapor tube, such that the air is compressed. The compressed air may be evacuated through the vent aperture. In this way, the leakage of the vapor substrate due to the compressed air can be avoided.
Preferably, the two-part tube body may be integrally-formed and made of a material which is stainless and corrosion resistant and readily conducts heat. When the vapor substrate is heated by the tube-shaped vaporizing core, the excessive heat energy can be quickly transferred to the vapor substrate disposed in the storage chamber by the two-part tube body, such that the vapor substrate may be preheated to improve fluidity.
Preferably, the vapor substrate may be cigarette liquid, tobacco tar having high viscosity, or waxy solid formed by solidification of tobacco tar, which produce vapor when being heated.
Preferably, the tube-shaped vaporizing core may comprise a porous ceramic tube, a porous quartz tube, or a porous carbon fiber tube, with a heating element being embedded inside.
Preferably, between the inner wall of the vaporizing tube and the tube-shaped vaporizing core, a liquid-permeable layer may be further provided.
Preferably, the liquid-permeable layer may be made of non-woven fabric, carbon fiber, quartz fiber, or organic cotton.
Preferably, the mouthpiece member may further comprise a mouthpiece sealing ring, a wall portion of the connecting end of the mouthpiece housing may be provided with a groove which extends axially and has an annular shape, and the mouthpiece sealing ring may be disposed in the groove and tightly abuts against an outer wall of the vapor tube.
Preferably, a metallic ring may be further disposed between an outer wall of the mouthpiece sealing ring and the mouthpiece housing.
Preferably, the connecting member may comprise a base provided with a through-hole extending axially, an upper portion of the base is located between the outer tube and the vaporizing tube, a lower portion of the base has an outer wall having a reduced outer diameter, and the outer wall is provided with connecting threads for connecting a battery rod to form an electronic cigarette by the electronic cigarette vaporizer and the battery rod, and a positive electrode is disposed in the through-hole of the base.
Preferably, two ends of the outer tube may be respectively connected with a metal sleeve.
AdvantagesBefore insertion of the mouthpiece member, the space between the outer wall of the two-part tube body and the inner wall of the outer tube is opened. Such structure facilitates filling of the vapor substrate. The connection mode, in which the mouthpiece member is inserted in the outer tube by an external force, facilitates machine/manual operation and further facilitates filling procedure at the sales area. During assembly of the mouthpiece member, the connecting end fits tightly between the outer tube and the vapor tube. The air between the outer tube and the vapor tube may be compressed and evacuated through the vent aperture, such that the pressure in the storage chamber may be reduced, preventing the vapor substrate from being squeezed out through the substrate through-hole 303 under the pressure to cause leakage. The integrally-formed two-part tube body is made of a material which readily conducts heat. When the tube-shaped vaporizing core is energized to work, excessive heat energy may be generated and absorbed and transferred to the vapor substrate by the two-part tube body, such that the tobacco tar having high viscosity, the waxy solid formed by solidification of tobacco tar, or the like, may be preheated to reduce viscosity and improve fluidity. It facilitates the vapor substrate to permeate through the substrate through-hole to the tube-shaped vaporizing core. In this way, more vapor substrate may be feed during vaporization, and more vapor may be produced in unit time, thereby providing good user experience.
In order to make purposes, technical solutions and advantages of the disclosure clearer, the disclosure will be further explained in detail with reference to drawings and embodiments described hereinafter.
For convenience of description, an electronic cigarette vaporizer of the disclosure is illustrated when it is vertically disposed, with a mouthpiece end being located in the upper position, as shown in the drawings. The terms, such as “upper”, “lower”, “upper portion”, “lower portion”, “upper end”, “lower end”, “upper surface”, “lower surface” as used in the disclosure, refer to position and orientation relationships when the electronic cigarette vaporizer is vertically disposed, with the mouthpiece end being located in the upper position.
EmbodimentsReferring to
Referring to
In the embodiment, the vapor substrate may comprise cigarette liquid, tobacco tar having high viscosity, waxy solid formed by solidification of tobacco tar, or the like, which produce vapor when being heated.
Referring to
In the embodiment of the disclosure, the mouthpiece member 1 is inserted in the outer tube 2 by an external force and is fastened by the tight fit connection. Before insertion of the mouthpiece member, the space between the outer wall of the two-part tube body 30 and the inner wall of the outer tube 2 is opened. Such structure facilitates filling of the vapor substrate, such as the cigarette liquid, tobacco tar having high viscosity, and waxy solid formed by solidification of tobacco tar. Hence, if the electronic cigarette vaporizer is going to be sold abroad, it is not necessary to prefill the vapor substrate before delivery. Instead, the vapor substrate may be filled after delivery to the sales area. Further, the connection mode, in which the mouthpiece member 1 is inserted in the outer tube 2 by an external force, facilitates machine/manual operation and further facilitates filling procedure at the sales area.
The integrally-formed two-part tube body 30 is made of a material which is stainless, corrosion resistant, and readily conducts heat, such as stainless steel. When the tube-shaped vaporizing core 31 is energized to work, excessive heat energy may be generated. As the two-part tube body 30 is made of a material which readily conducts heat, the excessive heat energy can be absorbed and transferred to the vapor substrate by the two-part tube body 30, such that the tobacco tar having high viscosity, the waxy solid formed by solidification of tobacco tar, or the like, may be preheated to reduce viscosity and improve fluidity. Then, the vapor substrate may permeate through the substrate through-hole 303 to the tube-shaped vaporizing core 31. In this way, more vapor substrate may be feed during vaporization, and more vapor may be produced in unit time, thereby providing good user experience.
In the embodiment, the tube-shaped vaporizing core 31 may be a porous ceramic tube, a porous quartz tube, or a porous carbon fiber tube, with a heating element being embedded inside.
