Peng further teaches the device wherein the holder comprises a body and has a first end and a second end opposite to the first end; and the first end is provided close to the heating element, and the base body is held on the second end ([0056]-[0057], Figs. 2-5; Annular extension 310b (holder) comprises a body having a first lower end (facing down as shown in Fig. 2) and a second upper end (facing up as shown in Fig. 2) opposite to the first end. The first lower end is close to heating coil 324 as shown in Figs. 4-5. The second upper end holds the heating plate 322). 1 Regarding Claim 13, Peng in view of Yu and Ma teaches the electronic vaporization device according to claim 12. Peng further teaches the device wherein the body is provided with a through hole to enable the heat of the heating element to be transferred to the thermistor through the through hole ([0056]-[0057], Figs. 2-5; Due to its annular shape, annular extension 310b (holder body) is necessarily provided with a through hole as shown in Fig. 2. Heat from heating coil 324 is able to transfer to thermistor 328 through the through hole). Regarding Claim 14, Peng in view of Yu and Ma teaches the electronic vaporization device according to claim 12. Peng further teaches the device wherein the holder further comprises a limiting part provided on the second end; and the limiting part is used for limiting the base body to move to hold the base body on the second end ([0056]-[0057], Figs. 2-5; Annular extension 310b (holder) has a second upper end (facing up as shown in Fig. 2). The horizontal surfaces above of the annular extension 310b can be regarded as a limiting part because they limit the movement of the heating unit 320 upward past the second upper end). Regarding Claim 15, Peng in view of Yu and Ma teaches the electronic vaporization device according to claim 11. Peng further teaches the device further comprising a base used for holding the heating element; and the holder is in contact with the base to enable the heat of the heating element to be transferred to the thermistor through the base and the holder ([0048], Figs. 3-4; Heating element 320 comprises a heating plate 322, a heating coil 324 (reading on the claimed heating element), and thermistor 328. [0052], the heating plate 322 covers the heating coil 324, and the plastic coating part 326 is formed on the heating plate 322 to form the heating unit 320. [0051], [0056]-[0057], Fig. 2; the periphery of the plastic-coated part 326 is welded to the inner wall of the oil cup body 310 at annular extension 310b (holder), so that the periphery of the plastic-coated part 326 is reliably connected to the inner wall of annular extension 310b (holder). Part 326 reads on the base used for holding heating coil 324 (heating element). Annular extension 310b (holder) is in contact with part 326 (base). As heating coil 324 (heating element), heating plate 322 (base body), thermistor 328, part 326 (base), and annular extension 310b (holder) are all in direct or indirect physical contact with each other, heat of heating coil 324 is necessarily capable of being transferred to the thermistor 328 through part 326 (base) and annular extension 310b (holder)). Claims 16-17 are rejected under 35 U.S.C. 103 as being unpatentable over Peng (CN 111802707 A, English Translation) in view of Yu (CN 205355787 U, cited on the IDS dated 7/28/2023, English Translation) and Ma (US 2023/0070240 A1) as applied to Claim 15, and further in view of Thomas (US 2023/0363458 A1). Regarding Claim 16, Peng further teaches the device wherein a face of the holder abuts an end of the base ([0051], [0056]-[0057], Fig. 2; A face of annular extension 310b (holder) directly abuts an end of part 326 (base)), but does not teach the device wherein the base is cylindrical, the first end of the holder is provided with a stepped face, and the stepped face abuts against an end of the base. Thomas, directed to electronic cigarettes ([0002]-[0004]), teaches an electronic vaporization device ([0058], Fig. 1; Aerosol provision device 100), comprising: a heating element ([0075]-[0080], Figs. 3-4; Aerosol provision device 100 comprises heater assembly 105 (heating element). Heater assembly 105 includes a susceptor arrangement 132 a funnel part 140. The susceptor 132 and funnel part 140 may be a one-piece component); a base used for holding the heating element ([0093], Fig. 4 and 6; Device 100 comprises second end support 230 (base) used for holding the funnel part 140 of heater assembly 105 (heating element)), wherein the base is cylindrical ([0083], Figs. 4 and 6; First section 141 of funnel part 140 is cylindrical. If second end support 230 (base) directly abuts first section 141 as shown in Fig. 4, it is reasonably understood that second end support 230 is cylindrical), a first end of the base is provided with a stepped face, and the stepped face abuts against an end of the heating element ([0093]-[0094], Figs. 4 and 6; A first end of second end support 230 (base) is provided with a stepped face which abuts and end of funnel part 140 (heating element). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide the device of Peng in view of Yu and Ma wherein the base is cylindrical as taught by Thomas because Peng, Yu, Ma, and Thomas are directed to electronic cigarettes, and changing the cross section of the base to cylindrical constitutes a change in form of shape to another known shape in the art. The change in form or shape, without any new or unexpected results, is an obvious engineering design. See MPEP § 2144.04 IV B. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide the device of Peng in view of Yu, Ma, and Thomas wherein the first end of the holder is provided with a stepped face, and the stepped face abuts against an end of the base similarly taught by Thomas because Peng, Yu, Ma, and Thomas are directed to electronic cigarettes, Peng discloses a face of the holder abuts an end of the base ([0051], [0056]-[0057], Fig. 2; A face of annular extension 310b (holder) directly abuts an end of part 326 (base)), and Thomas demonstrates that a stepped face can ensure that two elements do not detach from each other, and that the stepped face can provide a suitable location for a sealing element to prevent leakage (Thomas, [0093]-[0094], [0104], Figs. 4 and 6), and this involves combining prior art elements according to known methods to yield predictable results. Regarding Claim 17, Peng in view of Yu, Ma, and Thomas teaches the electronic vaporization device according to claim 16, but does not teach the device further comprising a leakproof piece used for preventing the liquid from flowing to the holder; and both the leakproof piece and the heating element are provided in the base, and the leakproof piece is provided between the heating element and the holder. Thomas, directed to electronic cigarettes ([0002]-[0004]), teaches an electronic vaporization device ([0058], Fig. 1; Aerosol provision device 100), comprising: a heating element ([0075]-[0080], Figs. 3-4; Aerosol provision device 100 comprises heater assembly 105 (heating element). Heater assembly 105 includes a susceptor arrangement 132 a funnel part 140. The susceptor 132 and funnel part 140 may be a one-piece component); a base used for holding the heating element ([0093], Fig. 4 and 6; Device 100 comprises second end support 230 (base) used for holding the funnel part 140 of heater assembly 105 (heating element)) a leakproof piece used for preventing the liquid from flowing out of the base, wherein both the leakproof piece and the heating element are provided in the base, and the leakproof piece is provided between the heating element and the base ([0104], Figs. 4 and 6; A second sealing member 245 (leakproof piece) forms a fluid seal between the heating assembly 105 and the second end support 230. Second sealing member 245 (leakproof piece) and funnel part 140 (heating element) are provided within support 230 (base). Member 245 is provided between funnel part 140 and support 230). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide the device of Peng in view of Yu, Ma, and Thomas further comprising a leakproof piece used for preventing the liquid from flowing out of the base, wherein both the leakproof piece and the heating element are provided in the base, and the leakproof piece is provided between the heating element and the base as taught by Thomas because Peng, Yu, Ma, and Thomas are directed to electronic cigarettes, Thomas demonstrates that the leakproof piece forms a fluid tight seal to prevent the flow of fluid into or out of the base (Thomas, [0104]), and this involves combining prior art elements according to known methods to yield predictable results. Further, if the leakproof piece is provided between the heating element and the base as taught by Thomas, the leakproof piece would be necessarily capable of preventing the liquid from flowing to the holder, and would necessarily be provided between the heating element and the holder because the holder abuts an external surface of the base ([0051], [0056]-[0057], Fig. 2; Annular extension 310b (holder) directly abuts an external surface of part 326 (base)).
