BACKGROUND
TECHNICAL FIELD
[0001] The disclosure relates to the field of electronic cigarettes, more particularly to an electronic cigarette vaporizer.
BACKGROUND
[0002] The 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.
[0003] 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.

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.
[0006] 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.
[0007] 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.
[0008] 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.
[0009] Preferably, between the inner wall of the vaporizing tube and the tube-shaped vaporizing core, a liquid-permeable layer may be further provided.

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.

DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS
DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS
[0027] 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.
[0028] 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.
[0029] Embodiments
[0030] Referring to FIGs.1-3, an electronic cigarette vaporizer according to an embodiment of the disclosure comprises an outer tube 2, a mouthpiece member 1 arranged at one end of the outer tube 2, a connecting member 4 arranged at the other end of the outer tube 2, and a vaporizing member 3 arranged inside the outer tube 2.
[0031] Referring to FIGs.4 and 5, the vaporizing member 3 comprises a two-part tube body 30 which is integrally-formed. The two-part tube Date Recue/Date Received 2021-09-20 Our Ref: 43970-9 CA National Phase of PCT/CN2020/093155 (CA2101253H-PCT) body 30 consists of a vapor tube 301 disposed at the upper position and having a smaller diameter, and a vaporizing tube 302 disposed at the lower position and having a greater diameter. The vapor tube 301 and the vaporizing tube 302 are connected with each other. The two-part tube body 30 is integrally-formed and is made of a material which is stainless and corrosion resistant and readily conducts heat, such as stainless steel. A
storage chamber for storing vapor substrate is formed between an outer wall of the two-part tube body 30 and an inner wall of the outer tube 2. A
tube-shaped vaporizing core 31 for vaporizing the vapor substrate to produce vapor is sleeved inside the vaporizing tube 302. A wall portion of the vaporizing tube 302 is provided with a substrate through-hole 303. An upper end of a wall portion of the vapor tube 301 is provided with a vent aperture 304.

A wall portion of the vaporizing tube 302 is provided with a substrate through-hole 303. An upper end of a wall portion of the vapor tube 301 is provided with a vent aperture 304.
[0032] 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.
[0033]
Referring to FIGs.5-7, the mouthpiece member 1 comprises a mouthpiece housing 10 having a mouthpiece end 101 and a connecting end 102. A vapor passage 103 extending through the mouthpiece end and the connecting end is formed in the center of the mouthpiece housing 10.
During assembly of the mouthpiece member 1, the connecting end 102 Date Recue/Date Received 2021-09-20 Our Ref: 43970-9 CA National Phase of PCT/CN2020/093155 (CA2101253H-PCT) fits tightly between the outer tube 2 and the vapor tube 301, such that the air between the outer tube 2 and the vapor tube 301, i.e., the air inside the storage chamber 5, is compressed. The compressed air may be evacuated through the vent aperture 304, such that the pressure in the storage chamber 5 may be reduced, preventing the vapor substrate from being squeezed out through the substrate through-hole 303 under the pressure of the compressed air to cause leakage. In this way, the leakage of the vapor substrate during assembly can be avoided.
Referring to FIGs.5-7, the mouthpiece member 1 comprises a mouthpiece housing 10 having a mouthpiece end 101 and a connecting end 102. A vapor passage 103 extending through the mouthpiece end and the connecting end is formed in the center of the mouthpiece housing 10.
During assembly of the mouthpiece member 1, the connecting end 102 Date Recue/Date Received 2021-09-20 Our Ref: 43970-9 CA National Phase of PCT/CN2020/093155 (CA2101253H-PCT) fits tightly between the outer tube 2 and the vapor tube 301, such that the air between the outer tube 2 and the vapor tube 301, i.e., the air inside the storage chamber 5, is compressed. The compressed air may be evacuated through the vent aperture 304, such that the pressure in the storage chamber 5 may be reduced, preventing the vapor substrate from being squeezed out through the substrate through-hole 303 under the pressure of the compressed air to cause leakage. In this way, the leakage of the vapor substrate during assembly can be avoided.
[0034] 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.
[0035] The integrally-formed two-part tube body 30 is made of a Date Recue/Date Received 2021-09-20 Our Ref: 43970-9 CA National Phase of PCT/CN2020/093155 (CA2101253H-PCT) 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.
[0036] 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.
[0037]
Referring to FIG.4, between the inner wall of the vaporizing tube 302 and the tube-shaped vaporizing core 31, a liquid-permeable layer 32 is provided in the embodiment, which is made of a material such as non-woven fabric, carbon fiber, quartz fiber, organic cotton.
Referring to FIG.4, between the inner wall of the vaporizing tube 302 and the tube-shaped vaporizing core 31, a liquid-permeable layer 32 is provided in the embodiment, which is made of a material such as non-woven fabric, carbon fiber, quartz fiber, organic cotton.
[0038]
Referring to FIGs.6-8, the mouthpiece member 1 further comprises a mouthpiece sealing ring 11. The wall portion of the connecting end 102 of the mouthpiece housing 10 is provided with a Date Recue/Date Received 2021-09-20 Our Ref: 43970-9 CA National Phase of PCT/CN2020/093155 (CA2101253H-PCT) groove 104 which extends axially and has an annular shape. The mouthpiece sealing ring 11 is disposed in the groove 104 and tightly abuts against an outer wall of the vapor tube 301. A metallic ring 12 is further disposed between an outer wall of the mouthpiece sealing ring 11 and the mouthpiece housing 10. Due to the metallic ring 12, the rigidity of the connecting end 102 can be improved, thereby preventing the mouthpiece housing 10 (made of plastic material) from being deformed under pressure, to cause loose connection which may lead to falling off of the mouthpiece housing, leakage of the vapor substrate, etc.

Referring to FIG.7, a series of arrows as shown in the drawing show a direction in which the vapor substrate flows. That is, the vapor substrate is preheated by the outer wall of the two-part tube body 30, and then flows downward from the storage chamber 5. It permeates through the substrate through-hole 303 of the vaporizing tube 302 into the tube-shaped vaporizing core 31. Then, by means of the heating element which is disposed in the tube-shaped vaporizing core 31 and is energized to generate heat, the vapor substrate is heated and vaporized to produce vapor. The vapor of the electronic cigarette may flow upward through a central passage of the tube-shaped vaporizing core 31 and then may be inhaled.
