Claims 1-4 are rejected under 35 U.S.C. 102(a)(1) and 102(a)(b) as being anticipated by Lin et al. (US 2022/0354164 A1, English translation for CN 110403253 A). Regarding claim 1, Lin discloses an electronic cigarette vaporizer – (construed as a vaporizer) to include hollow tube 3, see at least FIG. 4 – (construed as a vaporization core), the hollow tube by its hollowness has an inner bottom, see at least FIG. 4 – (construed as a vaporization cavity at an inner bottom of a vaporization core). The vaporizer further having a housing 1 including a mouthpiece end 10 and an insertion portion 14 – (construed as a connecting end). The mouthpiece opening/end is provided with a mouthpiece extending downwards and integrally formed with a mouthpiece housing 11 – (construed as a mouthpiece tube), the insertion portion/connecting end is provided with an opening closed by a base member 6 – (construed as a bottom cap), the insertion portion/connecting end is capable of being connected with a battery part to form an electronic vaporizing device, see at least [0005]. Components of a vaporizing base 5 and hollow tube 3, see at least FIG. 6 – (construed as a vaporizing assembly) is provided inside the housing and is connected between the mouthpiece housing/tube and the base member/bottom cap. A liquid storage chamber 13 is defined between the vaporizing assembly and an inner wall of the housing 1, see at least FIG. 3. The vaporizing assembly includes a hollow tube/vaporization core and a vaporizing base 5, a bottom portion of the vaporizing base is disposed on the base member/bottom cap, a lower portion of the hollow tube/vaporization core is inserted in a concave cavity 52 – (construed as a central accommodation cavity) of the vaporizing base, an upper end of the hollow tube/vaporization core is sleeved on a lower end of the mouthpiece housing/tube, see at least FIGS 4, 6, 7. The vaporization cavity is provided at the inner bottom of the hollow tube/vaporization core, the hollow tube/vaporization core is provided with a central through-hole extending vertically, the base member/bottom cap is centrally provided with an air intake pipe 66 – (construed as a bottom cap air inlet), see at least FIG. 11. The vaporizing base is centrally provided with a first air inlet 53 – (construed as a vaporizing base inlet hole), the first air inlet/vaporizing base inlet hole is in communication with the hollowness of the hollow tube/vaporization cavity, and the hollowness of the hollow tube/vaporization cavity is in communication with the central through-hole, the mouthpiece housing/tube, and the mouthpiece in an upward direction, see at least FIGS. 3, 4. Regarding claim 2, Lin further discloses the vaporizing assembly further comprises a support plate 7 – (construed as an isolation plate placed on an upper surface of the vaporizing base), wherein as best depicted in FIG. 2, the plate has is provided with a plate central hole, a wall of the lower portion of the hollow tube/vaporization core is integrally engaged into the isolation plate central hole, and the isolation plate is provided on two sides with isolation plate filling through-holes. Regarding claim 3, Lin further discloses the vaporizing base is provided on two sides with holes 56 – (construed as vaporizing base filling through-holes), and the base member/bottom cap is provided with plungers 63 – (construed as plugs) for respectively plugging the holes/vaporizing base filling through-holes at positions corresponding to respective vaporizing base filling through-holes, see at least [0042], FIGS. 5, 7, 10. Regarding claim 4, Lin further discloses a seal plate 661 – (construed as a cover plate) is disposed above the air intake pipe/bottom cap air inlet, and a second air inlet 61 – (construed as an outlet opening) for the bottom cap air inlet is provided on a side wall of the lower portion of the seal/cover plate, at a position above an inner bottom plate of the bottom cap, see at least FIGS. 10, 11. Allowable Subject Matter Claims 5-12 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: The closest prior art of record Lin does not teach or reasonably suggest forming the hollow tube/vaporization core such that it includes: a sleeve, a liquid guiding member, a heating sheet, and electrode leads, wherein the liquid guiding member is disposed inside the sleeve, the sleeve is provided with side wall through-holes above the vaporizing base, the side wall through-holes are covered by an outer wall of the liquid guiding member, the liquid guiding member is provided with the central through-hole, the heating sheet is disposed at bottom of the liquid guiding member, the electrode leads are disposed on two sides of the heating sheet, a portion of the sleeve below the heating sheet is provided with a bottom cavity which defines the vaporization cavity, and a portion of the sleeve above the liquid guiding member is provided with an empty chamber which defines the vapor chamber.
