An annular air inlet channel 220 that is in communication with the mounting cavity 2111 is formed between the inner wall surface of the lower shell 21 and the outer wall surface of the battery 22.
In some embodiments, the mounting base 23 may be integrally formed by an elastic material such as silicone, and may include a lower sleeve portion 231 arranged on a lower part and an upper sleeve portion 232 arranged on an upper part. The lower sleeve portion 231 may be closely embedded in the insertion portion 211, where a vent groove 2110 connecting the mounting cavity 2111 with the air inlet channel 220 is provided on the side wall of the insertion portion 211. A bottom part of the lower sleeve portion 231 is open, and the airflow sensor 24 may be inserted into the lower sleeve portion 231 through the open bottom part and in communication with the mounting cavity 2111.

The lower end of the upper shell 11 is embedded in the lower shell 21, and the upper shell 11 and the lower shell 21 are assembled to form a shell of the electronic vaporization device. In the upper shell 11, a liquid storage cavity 110 configured to store a liquid vaporizable substrate and an air outlet channel 1110 configured to export vapor are formed. The heating component 14 is arranged in the upper shell 11 and is in communication with the liquid storage cavity 110 in a liquid guiding manner. A vaporization cavity 150 that is in communication with the air outlet channel 1110 is formed between the heating base 15 and the vaporization base 13, and the heating component 14 is at least partially arranged in the vaporization cavity 150.
An air outlet tube 111 may be arranged in the longitudinal direction in the upper shell 11. The inner wall surface of the upper shell 11 and the outer wall surface of the air outlet tube 111 define the annular liquid storage cavity 110, and the inner wall surface of the air outlet tube 111 defines the air outlet channel 1110. In this embodiment, the air outlet tube 111 may be integrally formed by downward extension of the top wall of the upper shell 11. The air outlet channel 1110 may be a conical chimney structure with the pore sizes gradually decreasing from the bottom to the top. By adopting this kind of chimney structure with a large bottom and a small top, when floating up in a chimney passage, the vapor may speed up due to the decreasing cross-sectional areas of the chimney passage. This is equivalent to an additional inhalation force in the air outlet channel 1110, so that the vapor can be inhaled out more easily. Meanwhile, due to an increasing rising rate of the vapor, vapor temperature may be increased, and a vapor amount increases accordingly, bringing a better user experience.
In some embodiments, the heating component 14 may include an elongated liquid absorbing wick 141, a heating wire 142 wound around the liquid absorbing wick 141, and two electrode lead wires 143 electrically connected with the heating wire 142. Two ends of the liquid absorbing wick 141 are respectively arranged in two opening grooves 1531 of the heating base 15 and are in communication with the liquid storage cavity 110 in a liquid guiding manner respectively. The liquid absorbing wick 141 may be made of a material such as a liquid absorbing cotton, a liquid absorbing cloth, or liquid absorbing fiber. The heating wire 142 is accommodated in the vaporization cavity 150, and is configured to generate heat to heat and vaporize the liquid vaporizable substrate absorbed by the liquid absorbing wick 141 after being powered. Two electrode holes 1502 corresponding to the two electrode lead wires 143 are arranged on the bottom wall of the vaporization cavity 150, where the two electrode lead wires 143 run through the two electrode holes 1502 respectively in a sealing manner to avoid liquid leakage.
In some embodiments, the heating base 15 may include a fixing portion 151 arranged in a lower part, a body portion 152 arranged in a middle part, and a carrying portion 153 arranged in an upper part. The body portion 152 is closely embedded in a bottom opening of the upper shell 11, and may be snapped and fixed onto the upper shell 11 by a snap-fit structure. In this embodiment, two sides of the body portion 152 protrude outward respectively to form a snap-fit 1521, a clamp groove 112 is formed on the upper shell 11 corresponding to the snap-fit 1521, and the snap-fit 1521 and the clamp groove 112 are snapped to each other, so as to snap and fix the heating base 15 onto the upper shell 11. The top surface of the carrying portion 153 recesses to form the vaporization cavity 150, where the two electrode holes 1502 are formed corresponding to the two electrode lead wires 143 of the heating component 14 on the bottom wall of the vaporization cavity 150, and the two electrode lead wires 143 may respectively run through the two electrode holes 1502 in a sealing manner to be connected with the battery 22. At least one vent hole 1501 may be further provided on the bottom wall of the vaporization cavity 150 to communicate the vaporization cavity 150 with the air inlet channel 220. In this embodiment, there are six vent holes 1501 which are provided perpendicular to the axial direction of the liquid absorbing wick 141 and are provided under the liquid absorbing wick 141, bringing a good air intake effect.
The fixing portion 151 may be formed by downward extension of a bottom part of the body portion 152, and the upper end surface of the fixing portion 151 may abut against the lower end surface of the upper shell 11. The upper end of the battery 22 may be closely embedded in the fixing portion 151 for fixing, and the upper end surface of the battery 22 may abut against the lower end surface of the body portion 152. In this embodiment, the battery 22 is fixed by using the fixing portion 151 of the heating base 15 and the upper sleeve portion 232 of the mounting base 23, so that there is no need to introduce an additional fixing element to fix the battery, thereby the cost is reduced. Moreover, the upper, lower, left, and right parts of the battery 22 are all fixed, bringing a good fixing effect. The fixing portion 151 may be in a discontinuous annular shape, and at least one (four in this embodiment) air guide groove 1510 is formed on the side wall thereof, so as to communicate the air inlet channel 220 with the vent holes 1501. Moreover, the fixing portion 151 is in a discontinuous annular shape, and can also elastically clamp the battery 22 to avoid damage to the battery 22 caused by rigid clamping. In this embodiment, the fixing portion 151 includes four clamping walls 1511 that are arranged symmetrically, where the four clamping walls 1511 correspondingly clamp four corners of the battery 22 respectively, and a gap between every two adjacent clamping walls 1511 form one air guide groove 1510. In some embodiments, the upper end surface of the battery 22 may recess inward to form a mounting groove 251. The power supply apparatus 2 may further include a liquid storage cotton 25 arranged in the mounting groove 251, where the liquid storage cotton 25 is arranged directly below the vaporization cavity 150 and may absorb and store leaked liquid leaking from the vaporization cavity 150. The carrying portion 153 may be formed by upward extension of a top part of the body portion 152, and an opening groove 1531 and a liquid flowing channel 1532 are respectively formed on each of two sides in the longitudinal direction of the carrying portion 153. Two ends of the liquid absorbing wick 141 are respectively arranged in the two opening grooves 1531 and extend into the liquid flowing channels 1532 to be in communication with the liquid storage cavity 110 in a liquid guiding manner.
In some embodiments, the vaporization base 13 may be integrally formed by an elastic material such as silicone, and may include a sleeve part 131 arranged on a lower part and a body portion 132 arranged on an upper part. The sleeve part 131 is annular and sleeved in a sealing manner between the upper shell 11 and the carrying portion 153, so as to achieve a sealing effect and avoid liquid leakage. The vaporization base 13 may further include two pressing portions 133 formed by downward extension of the two opening grooves 1531 corresponding to two sides of a bottom part of the body portion 132 respectively. The two pressing portions 133 respectively press the two ends of the liquid absorbing wick 141 and may form a seal structure to avoid a case that the liquid vaporizable substrate in the liquid storage cavity 110 enters the vaporization cavity 150 and causes liquid leakage. The present invention uses cooperation of the silicone vaporization base 13 and the heating base 15 to implement a vaporization structure, reducing elements required to fix the heating component 14, so that the electronic vaporization device has fewer parts, fewer mounting steps, and costs thereof are reduced. Moreover, few parts indicate a small cumulative tolerance, so that assembling and sealing are reliable.
Two liquid guide holes 1310 are formed between the inner wall surface of the sleeve part 131 and the outer wall surface of the pressing portion 133, where the two liquid guide holes 1310 are provided corresponding to and in communication with the two liquid flowing channels 1532 respectively, so as to communicate the liquid storage cavity 110 with the two liquid flowing channels 1532. An air guide channel 1311 may be further formed on the outer peripheral wall of the sleeve part 131, where the air guide channel 1311 may communicate the liquid storage cavity 110 with outside to supply air to the liquid storage cavity 110, so as to realize air-liquid equilibrium and smoother liquid flowing from the liquid storage cavity.
Specifically, in this embodiment, a plurality of horizontal annular protrusions 1313 and a plurality of horizontal annular grooves 1312 are formed on the outer peripheral wall of the sleeve part 131. One annular groove 1312 is formed between every two adjacent annular protrusions 1313, and an air inlet opening 1314 is provided on a side of each annular protrusion 1313 so as to communicate every two adjacent annular grooves 1312 in an up-down direction thereof. The plurality of air inlet openings 1314 and the plurality of annular grooves 1312 are in communication to form the air guide channel 1311. The air inlet openings 1314 of the plurality of annular protrusions 1313 may be provided on the same or different sides of the sleeve part 131. In this embodiment, the air inlet openings 1314 of every two adjacent annular protrusions 1313 are respectively provided on two opposite sides of the sleeve part 131 in the longitudinal direction. In addition, the annular protrusions 1313 are interference-fitted in the upper shell 11, bringing a better sealing effect. The annular grooves 1312 may also absorb and store a certain amount of leaked liquid by a capillary force, so as to further reduce liquid leakage. When the air pressure in the liquid storage cavity 110 decreases (for example, when the electronic vaporization device is transported by an airplane), volumes of air bubbles in the liquid storage cavity 110 increase, and the liquid vaporizable substrate overflowing through the air guide channel 1311 will be accommodated in the annular grooves 1312, thereby reducing liquid leakage. When the air pressure in the liquid storage cavity 110 returns to normal, the liquid vaporizable substrate stored in the annular grooves 1312 may reflux to the liquid storage cavity 110 through the air guide channel 1311, thereby improving reducing negative pressure liquid leakage. A width of each of the annular grooves 1312 may range from 0.1 mm to 0.5 mm, and preferably range from 0.2 mm to 0.4 mm.
A bottom surface of the body portion 132 may abut against the top surface of the carrying portion 153, and a through hole 130 is provided through the body portion 132 in the longitudinal direction. The through hole 130 may include a first hole section 1301 and a second hole section 1302 that are in communication sequentially from the bottom to the top, and the pore size of the second hole section 1302 is larger than that of the first hole section 1301. The lower end of the air outlet tube 111 is closely embedded in the second hole section 1302 and is in communication with the first hole section 1301, and the lower end surface of the air outlet tube 111 may abut against a step surface 1304 formed between the first hole section 1301 and the second hole section 1302. The inner wall surface of the second hole section 1302 may further protrude radially inward to form at least one annular seal portion 1305, where the annular seal portion 1305 is in interference fit with the air outlet tube 111 to improve sealing performance. The first hole section 1301 is provided corresponding to and in communication with the vaporization cavity 150, and the pore size of the first hole section 1301 is the same as the inner diameter of the lower end of the air outlet tube 111, so that the vapor may flow out more smoothly. A chamfer 1303 may be arranged at the bottom part of the first hole section 1301, where the chamfer 1303 may reduce a vortex flow, and the vapor in the vaporization cavity 150 flows out along the chamfer 1303, so that the vapor may flow out more smoothly.
Therefore, the air inlet hole 210, the mounting cavity 2111, the vent groove 2110, the air inlet channel 220, the air guide groove 1510, the vent hole 1501, the vaporization cavity 150, the first hole section 1301, and the air outlet channel 1110 are in communication sequentially to form a complete vapor conveying channel.
As shown in FIG. 2 and FIG. 7, in some embodiments, the vaporizer 1 may further include a mouthpiece sleeve 12. The mouthpiece sleeve 12 may be integrally formed by a silicone material, and may include an outer sleeve 121 sleeved outside the upper end of the upper shell 11, a sealing plug 122 extending downward from a top part of the outer sleeve 121, and an edge dismounting groove 123 surrounding the sealing plug 122. The sealing plug 122 is plugged in a sealing manner in the upper end of the air outlet channel 1110, and the edge dismounting groove 123 is annular and may be formed by the inner wall surface of the outer sleeve 121 recessing inward. The shape and the size of the edge dismounting groove 123 match the shape and the size of an exit of the air outlet channel 1110. For example, the size of the edge dismounting groove 123 may be the same as or slightly larger than the size of the exit of the air outlet channel 1110. The mouthpiece sleeve 12 may not only block and close the vaporizer, but also separate the sealing plug 122 by tearing an edge dismounting groove structure. After the sealing plug 122 is disassembled, the outer sleeve 121 may be used as a protective sleeve when a plurality of people share and use the product (that is, other people may use the electronic vaporization device through the outer sleeve 121).
