TECHNICAL FIELD
[0001] The disclosure relates to the technical field of electronic cigarette vaporizers, and more particularly, the disclosure relates to an electronic cigarette vaporizer for using solid e-cigarette oil.
BACKGROUND
[0002] An electronic cigarette generally includes a battery part and a vaporizer which are connected with each other. The battery part is mounted with a battery for supplying power to the vaporizer. Usually, the vaporizer of the electronic cigarette comprises a heating element for atomizing the e-cigarette oil in the liquid state into e-cigarette vapor or aerosol for users to vape during operation. As the e-cigarette oil in the liquid state is prone to leakage during transportation, storage, and use, e-cigarettes which can use paste-like solid e-cigarette oil have gradually emerged in the market.
[0003] The structure of an electronic cigarette vaporizer for using solid e-cigarette oil in the market usually employs a heating element in a type of a heating plate, wherein the vaporizing chamber and the oil storage chamber of the heating element are the same one. In other words, the vapor produced by heating the solid e-cigarette oil is discharged through the oil storage chamber. In such a case, excess e-cigarette oil melted during high-temperature vaporization is prone to leakage from the vapor exhaust port. Another method is known in the market, which uses heating wires to directly heat the solid e-cigarette oil. However, according to this method, the heating wires heat and melt the solid e-cigarette oil into liquid e-cigarette oil which is prone to leakage too. Besides, after a period of use of the solid e-cigarette oil within the oil storage chamber, the side of the solid e-cigarette oil in contact with the heating wires will be consumed and thus the solid e-cigarette oil will gradually lose contact with the heating wires in the absence of external force. Consequently, poor vaporization and dry burning may occur.

The oil-absorbing ring 78 is made of oil-absorbing material such as cotton material, to collect and absorb the dripped e-cigarette oil that is un-vaporized during the vaporization of the porous vaporizing core 6, thereby preventing the un-vaporized e-cigarette oil droplets from being inhaled by the user.
[0025] Referring to FIG.9, the outer wall of the lower portion of the mouthpiece base 2 is fitted on the inner wall of the upper portion of the inner tube 5. A third sealing sleeve 25 is provided between the mouthpiece base 2 and the inner tube 5, to seal the gap therebetween and prevent air or oil leakage. The push rod head 33 of the spring-force push rod mechanism 3 protrudes into the inner tube 5. An oil storage chamber 50 for accommodation of the solid e-cigarette oil is located between the push rod head 33 extending in the inner tube 5, and the porous vaporizing core 6. Under the elastic force of the spring 31, the push rod 32 pushes the solid e-cigarette oil to abut against the porous vaporizing core 6. All sealing sleeves mentioned in the disclosure can be made of silicone material. The sealing sleeves made of silicone material possess excellent sealing performance including high temperature resistance and wear resistance.
[0026] Referring to FIGs.9-10, the upper end of the porous vaporizing core 6 is further connected with an oil guiding ring 9. The inner wall of the oil guiding ring 9 is designed to define an inclined surface 91 extending downwards and inwards. The oil guiding ring 9 can facilitate an accumulation of the solid e-cigarette oil near the tube wall of the inner tube 5 into the oil guiding groove 60 of the porous vaporizing core 6 along the inclined surface 91 under the pressure of the push rod head 33. The oil guiding ring 9 can be made of dense ceramic.
[0027] Referring to FIGs.11-12, the porous vaporizing core 6 consists of a porous body 61, a heating resistor 62, and electrode leads 63. The upper portion of the porous body 61 is provided with an oil guiding groove 60, the bottom portion is arranged with the heating resistor 62, and two ends of the heating resistor 62 are respectively connected with an electrode lead 63. The porous body 61 can be made of porous ceramic.
[0028] Referring to FIGs.13-14, the connecting member 7 comprises a negative base 71, an insulating ring 72, and a positive pole 73. The upper portion of the negative base 71 has a cavity structure for accommodation of an oil-absorbing ring 78. The outer wall of the upper portion of the negative base 71 is fitted on the inner wall of the bottom end of the outer tube 4. The outer diameter of the outer wall of the lower portion of the negative base 71 tapers to form a step together with the outer wall of the upper portion. The lower portion of the negative base 71 is centrally provided with a base through-hole 710, in which the positive pole 73 is disposed. The insulating ring 72 is fitted between the base through-hole 710 and the positive pole 73. The outer wall of the lower portion of the negative base 71 is provided with a first air inlet hole 711 in communication with the base through-hole 710. The outer wall of the lower portion of the negative base 71 is provided with external threads 712 for connection with the connecting threads of the battery part. The positive pole 73 has a hollow structure which is axially provided with a second air inlet hole 730.
[0029] Referring to FIG.9, during operation of the electronic cigarette vaporizer for using solid e-cigarette oil in the embodiment, a negative pressure, indicated by a series of upward arrows as shown in FIG.9, may be generated in the electronic cigarette vaporizer due to the suction force when a user takes a puff through the mouthpiece opening 10. Thus, external air may enter the vaporizing chamber 82 upwards from the bottom through the first air inlet hole 711 and the second air inlet hole 730. At the moment, the heating resistor 62 disposed at the bottom portion of the porous body 61 may be powered on to generate heat. The solid e-cigarette oil stored in the oil storage chamber 50 may be pressed downwards into the oil guiding groove 60 of the porous vaporizing core 6 by the push rod head 33. The heat energy may be conducted upwards from the bottom portion of the porous body 61 to the bottom portion of the oil guiding groove 60, to melt the solid e-cigarette oil in contact with the bottom portion of the oil guiding groove 60. Then, the melted e-cigarette oil in the porous body 61 may be permeated downwards to the bottom portion of the porous body 61. The heating resistor 62 may heat the e-cigarette oil permeated to the surface of the bottom portion of the porous body 61. The e-cigarette oil may be vaporized at high temperatures, into e-cigarette vapor. Then, the e-cigarette vapor may be distributed downwards into the vaporizing chamber 82, carried by the flow of incoming external air and flow out through the first vapor outlet hole 80 into the vapor discharge passage 45. After that, the vapor may continue to flow upwards, passing through the second vapor outlet hole 22 into the vapor cavity 23 at the upper portion of the mouthpiece base 2, and finally flow through the mouthpiece opening 10 into the user's mouth.
