An embodiment of the present disclosure provides an electronic vaporization device 100. Referring to FIGS. 1-3 , the electronic vaporization device 100 includes a first shell 10, a liquid storage part 20 and a second shell 30. The liquid storage part 20 internally has a liquid storage chamber for storing a liquid substrate and an airflow channel for guiding an air flow. An outer surface of the liquid storage part 20 includes a first part 210 and a second part 220. A protrusion part 211 protrudes from the outer surface 210 of the first part or the outer surface 220 of the second part. The first shell 10 covers the first part 210 of the outer surface of the liquid storage part 20 and is fixedly connected to the liquid storage part 20. The second shell 30 covers the second part 220 of the outer surface of the liquid storage part 20 and is fixedly connected to the liquid storage part 20. Meanwhile, the protrusion part 211 is at least not covered by the first shell 10 and the second shell 30. Since the electronic vaporization device 100 is divided into the first shell 10, the liquid storage part 20 and the second shell 30. During assembly, only the first shell 10 and the second shell 30 need to be fixedly connected to the liquid storage part respectively, thereby facilitating production.
The fixed connection may be detachable connection or non-detachable connection. In a case of non-detachable connection, when the first shell 10 and the second shell 30 are respectively fixedly connected to the liquid storage part 20, the electronic vaporization device 100 can be constructed as an integrated body. When the user needs to fill the liquid substrate into the liquid storage chamber of the liquid storage part 20 by himself, the fixed connection can be detachable connection, so that the user conveniently disassembles the first shell 10 or the second shell 30 from the liquid storage part 20 and then fill the liquid substrate into the liquid storage chamber after the liquid substrate is consumed up.
In some embodiments, the protrusion part 211 is configured to be substantially annular. That is, the protrusion part 211 protrudes along the outer surface 210 of the first part or the outer surface 220 of the second part in a circumferential direction. The protrusion part 211 is configured to be substantially annular, which can make the overall appearance of the electronic vaporization device 100 more harmonious and beautiful.
In some embodiments, the protrusion part 211 is made of a transparent material, so that the airflow channel and the liquid storage chamber in the liquid storage part 20 can be observed through the protrusion part 211 at the same time, which is convenient for the user to observe the remaining liquid volume of the electronic vaporization device 100 and the smoke volume of the aerosol during inhalation.
In the above embodiment, the protruding height of the protrusion part 211 is substantially the same as the shell thicknesses of the first shell 10 and the second shell 30. When the first shell 10 and the second shell 30 cover over the liquid storage part 20, the first shell 10 and the second shell 30 abut against the protrusion part 211 of the liquid storage part 20 respectively. Since the protruding height of the protrusion part 21 is substantially the same as the shell thickness of the first shell 10 and the second shell 30, after the first shell 10 and the second shell 30 cover over the liquid storage part 20, the shell surface of the electronic vaporization device 100 can be made flush, and the flush surface is beneficial to improving the appearance of the electronic vaporization device 100.
Certainly, in some other embodiments, the protruding height of the protrusion part 21 may only be substantially the same as the thickness of any one of the first shell 10 or the second shell 30 and does not need to be the same as the thickness of both the first shell 10 and the second shell 30.
Further referring to FIGS. 5 and again, FIGS. 5 and 6 respectively show a three-dimensional schematic diagram and a schematic cross-sectional diagram of the liquid storage part 20 in a direction. The housing of the liquid storage part 20 has a proximal end 211 and a distal end 212 opposite to each other, and both the proximal end 211 and the distal end 212 are open. An axially extending chamber structure 22 is arranged inside the housing, a liquid storage chamber 221 is arranged inside the chamber structure 22 and configured to store a liquid substrate, such as vaporable medicinal liquid or e-cigarette liquid, and the airflow channel is defined and formed between an outer wall of the chamber structure 22 and an inner wall of the liquid storage part 20. Aerosol released from the electronic vaporization device 100 that vaporizes the liquid substrate can flow to the opening at the proximal end 211 through the airflow channel and escape from the liquid storage part 20 through the opening at the proximal end 211.
Further, a partition wall 2212 extends radially inside the chamber structure 22. The partition wall 2212 divides the interior of the chamber structure 22 into a liquid storage chamber 221 and a first accommodating chamber 223. The first accommodating chamber 223 accommodates a vaporization element 80 of the electronic vaporization device 100. The vaporization element 80 is in fluid communication with the liquid storage chamber 221, so that the liquid substrate in the liquid storage chamber 221 can flow onto the vaporization element 80 in the first accommodating chamber 223 for vaporization. Specifically, a liquid guide opening 2213 is formed in the partition wall 2212, and the liquid substrate in the liquid storage chamber 221 can flow to the vaporization element 80 through the liquid guide opening 2213. The liquid storage chamber 221 and the first accommodating chamber 223 are distributed on two sides of the liquid guide opening 2213.
In some embodiments, in the case where the chamber structure 22 axially extends inside the housing 21, the chamber structure 22 divides the interior of the housing 21 into a liquid storage chamber 221, a first chamber 2221 and a second chamber 2222 that are isolated from each other. The first chamber 2221 and the second chamber 2222 are distributed on two sides of the liquid storage chamber 221 and aerosol can flow through the first chamber 2221 and the second chamber 2222 respectively. That is, the airflow channel is divided into a first airflow channel 2221 and a second airflow channel 2222. Preferably, the dimensions of the first airflow channel 2221 and the second airflow channel 2222 are substantially the same in the same cross section, so that aerosol can escape from the liquid storage part 20 more smoothly.
Specifically, one set of opposite side walls 222 of the chamber structure 22 is respectively connected between the opposite inner walls of the liquid storage part 20, while other side walls of the chamber structure 22 are directly formed by the inner walls of the liquid storage part 20, so the interior of the housing 21 is divided into the liquid storage chamber 221, the first chamber 2221 and the second chamber 2222 by the side walls 222. In other embodiments of the present disclosure, there may be a gap between the outer wall of the chamber structure 22 and the inner wall of the housing 21 in the circumferential direction, and the gap may be used to form an airflow channel.
The electronic vaporization device 100 further includes a first seal member 40 for sealing the liquid storage chamber 221. Further referring to FIGS. 7 and 8 , FIGS. 7 and 8 respectively show three-dimensional schematic diagrams of the first seal member 40 in two directions. The first seal member 40 is made of a flexible soft rubber material, such as silicone or rubber. The first seal member 40 includes an end surface 41 and a side wall 42 extending from the end surface 41 in a direction away from the liquid storage chamber 221. The end surface 41 and the side wall 42 define and form a second accommodating chamber 43, and the second accommodating chamber 43 is configured to hold the vaporization element 80 of the electronic vaporization device. A liquid guide hole 411 is formed in the end surface 41 and the first seal member 40 is interference-fitted in the first accommodating chamber 223, so that the first seal member 40 elastically abuts against the inner wall of the first accommodating chamber 223 and moreover the liquid guide hole 411 of the first seal member 40 communicates with the liquid guide opening 2213. The liquid substrate in the liquid storage chamber 221 cannot leak through an assembly gap between the vaporization element 80 and the inner wall of the second accommodating chamber 223. The first seal member 40 provides a seal between the vaporization element 80 and the inner wall of the first accommodating chamber 223, and the liquid substrate can only flow to the vaporization element 80 in the second accommodating chamber 43 through the liquid guide opening 2213 and the liquid guide hole 411.
Further referring to FIG. 9 , the vaporization element 80 includes a porous body 81 and a heating element 82 combined on the porous body 81. The porous body 81 can be made of a hard capillary structure, such as porous ceramics, porous glass ceramics, and porous glass. In the embodiments, the porous body 81 may be generally but not limited to a block-shaped structure. According to the usage situation, the porous body 81 includes a liquid absorbing surface 811 and a vaporization surface 812 oppositely arranged along the axial direction of the electronic vaporization device 100, i.e., upper and lower surfaces of the block-shaped porous body 81 shown in FIG. 8 . The liquid absorbing surface 811 is configured to absorb the liquid substrate, and the heating element 82 is combined with the vaporization surface 812 to heat the vaporized liquid substrate. The porous body 81 is at least partially accommodated in the second accommodating chamber 43. Since the first seal member 40 is made of a flexible material, the porous body 80 can be tightly fitted in the second accommodating chamber 43 through an interference fit. In this case, the liquid absorbing surface 811 of the porous body 81 is accommodated in the second accommodating chamber 43 and faces the liquid guide hole 411 of the first seal member 40, so that the liquid substrate can flow to the liquid absorbing surface 811 through the liquid guide hole 411 and further flow to the vaporization surface 812 through the internal microporous structure of the porous body 81.
The heating element 82 is preferably formed on the vaporization surface 812 by mixing conductive raw material powder with a printing assistant to form a slurry and then sintering after printing according to a proper pattern, so that an entire surface or most of the surface of the heating element is closely attached to the vaporization surface 812, and the heating element has effects such as high vaporization efficiency, less heat loss, and dry-burn prevention or dry-burn reduction. In some embodiments, the heating element 82 may be in a variety of structural forms. The heating element 82 may be a sheet-shaped heating body, or in other forms such as a heating mesh, a disc-shaped heating body formed by a spiral heating wire, or a heating film, that is combined with the vaporization surface 812 and has a specific pattern. For example. the specific pattern may be a serpentine shape. In some embodiments, the heating element 82 may be made from a material such as stainless steel, nickel chromium alloy, iron chromium aluminum alloy, or metal titanium. Therefore, when the liquid substrate flows onto the vaporization surface 812, the heating element 82 on the vaporization surface 812 can heat and vaporize the liquid substrate, and release the aerosol generated after vaporization from the vaporization surface 812.
Further, the chamber structure 22 is further provided with a liquid filling opening end 2211 for filling liquid. Before the first shell 10 and the liquid storage part 30 are connected, the liquid substrate can be filled into the liquid storage chamber 221 through the liquid filling opening end 2211 in advance. After the liquid substrate is filled, the first shell 10 is fixedly connected to the liquid storage part 30.
Further, in order to prevent the liquid substrate from leaking from the above-mentioned liquid filling opening end 2211 when the electronic vaporization device 100 is turned upside down, the electronic vaporization device 100 further includes a second seal member 50. FIGS. and 11 respectively show three-dimensional schematic diagrams of the second seal member 50 in two directions. The second seal member 50 is also made of a flexible soft rubber material such as silicone or rubber. The second seal member 50 has an upper surface 51 and a lower surface 52 opposite to each other, as well as a side wall extending between the upper surface 51 and the lower surface 52. A plurality of protrusions 511 axially extend from the upper surface 51 toward the first shell 10, and the plurality of protrusions 511 form a clamping space 512. A first insertion part 521 axially extends from the lower surface 52 toward the liquid storage part 20, and a rib 5211 is arranged around the outer wall of the first insertion part 521. The first insertion part 521 is inserted into the liquid storage chamber 221 through the opening end 2211 of the liquid storage chamber 251. Moreover, the cross-sectional shape of the first insertion part 521 is adapted to the opening shape of the opening end 2211 of the liquid storage chamber 221, so the first insertion part 521 can be tightly fitted to the end wall of the opening end 2211 through an interference fit, thereby blocking the opening end 2211 of the liquid storage chamber 221 and preventing the liquid substrate from flowing out of the opening end 2211 of the liquid storage chamber 221 when the vaporizer 100 is turned upside down. Moreover, in order to prevent the first seal member from falling into the liquid storage chamber 221 due to the bumping of the electronic vaporization device 100 during transportation, the cross-sectional area of the first insertion part 521 is smaller than the area of the lower surface 52, so that a part of the lower surface 52 abuts against the end surface of the opening end 2211 of the liquid storage chamber 221, thereby preventing the first seal member 40 from falling into the liquid storage chamber 221.
Further referring to FIG. 12 , FIG. 12 shows a schematic cross-sectional diagram of the first shell 10 in a direction. One end of the first shell 10 is provided with an air outlet hole 12, through which the aerosol generated by vaporization can escape from the vaporizer 100, and the user can inhale the aerosol at the air outlet hole 12. The other end opposite to the air outlet hole 12 is configured as an open end 13, and the proximal end 211 of the liquid storage part 20 extends into the first shell 10 through the open end 13. The first shell 10 is hollow so that the aerosol generated by the vaporization element 80 can flow to the proximal end 211 of the liquid storage part 20 through the first airflow channel 2221 and the second airflow channel 2222, and further enter the interior of the first shell 10 through the opening of the proximal end 211, and then be discharged from the air outlet hole 12 of the first shell 10.
The first shell 10 is internally provided with a clamping part 14 that can be partially clamped in the clamping space 512. The clamping part 14 is formed by extending the inner wall of the first shell 10. The clamping part 14 has a second insertion part 141 extending axially toward the open end 13 of the first shell 10. A second through hole 53 axially penetrating through the body of the second seal member 50 is also formed in the second seal member 50. When the first shell 10 is engaged with the liquid storage part 20, the clamping part 14 is clamped in the clamping space 512 and the second insertion part 141 is inserted into the second through hole 53 at the same time. It is easy to understand that the cross-sectional shape of the second insertion part 141 is adapted to the shape of the second through hole 53 so that the second insertion part 141 and the second through hole 53 achieve an interference fit, and the second insertion part 141 can be tightly fitted to the hole wall of the second through hole 53 in a circumferential direction, thereby sealing the second through hole 53 and preventing the liquid substrate in the liquid storage chamber 221 from leaking through the second through hole 53 when the electronic vaporization device 100 is turned upside down.
In this embodiment, forming the second through hole 53 in the second seal member 50 is to discharge part of the air out of the liquid storage chamber 221 through the second through hole 53 when the second seal member 50 is inserted into the liquid storage chamber 221. Specifically, in actual production and assembly, the liquid substrate is filled into the liquid storage chamber 221 in advance, and then the second seal member 50 is installed at the opening end 2211 of the liquid storage chamber 221. In this case, with the insertion of the second seal member 50, the air in the liquid storage chamber 221 is compressed, and part of the air is discharged from the second through hole 53. Then, the first shell 10 is assembled on the liquid storage part 20, and at the same time, the second insertion part 141 of the first shell 10 is inserted into the second through hole 53. In this case, although the air in the liquid storage chamber 251 will also be compressed with the insertion of the second insertion part 141, part of the air is already discharged from the second through hole 53, and only a small amount of air in the liquid storage chamber 221 compresses the liquid substrate. The liquid substrate will not flow too much to the vaporization element 80 under the action of a small amount of air pressure to cause leakage. However, if the second through hole 53 is not formed in the second seal member 50 and the second seal member 50 is a completely closed seal member, as the second seal member 50 is inserted into the liquid storage chamber 221, the air in the liquid storage chamber 221 is compressed and cannot be discharged, the compressed air will squeeze the liquid substrate, and too much liquid substrate will flow to the vaporization element 80 under the action of the relatively large gas pressure, thus easily causing leakage.
Further, When the second insertion part 141 is inserted into the second through hole 53, the second seal member 50 may sag under the extrusion force of the second insertion part 141, thereby causing a gap between the second seal member 50 and the inner wall of the liquid storage chamber 221 and affecting the sealing performance of the second seal member 50. In order to avoid this problem, the second seal member 50 is provided with the above-mentioned protrusions 511. When the first shell 10 is engaged with the liquid storage part 20, the clamping part 14 of the first shell 10 is located in the clamping space 512 of the second seal member 50, the protrusions 511 clamp the clamping part 14 to reduce the extrusion force exerted by the second insertion part 141 on the second seal member 50, thereby effectively preventing the second seal member 50 from sagging under the extrusion force.
In some embodiments, the first airflow channel 2221 and the second airflow channel 2222 have a first air outlet port 22211 and a second air outlet port 22221 through which aerosol escapes from the liquid storage part 20, as shown in FIG. 5 . The heights of the first air outlet port 22211 and the second air outlet port 22221 are both less than the height of the liquid filling opening end 2211, so that the volume of the liquid storage chamber 221 can be increased, thereby increasing the liquid volume of the liquid substrate that can be stored.
Further, the electronic vaporization device 100 further includes a ventilation channel for communicating with the external air and the liquid storage chamber 221 to guide the external air into the liquid storage chamber 221, thereby preventing the generation of negative pressure in the liquid storage chamber 221 with the consumption of the liquid substrate and further preventing the vaporization element 80 from dry burning which occurs if the liquid substrate cannot flow smoothly to the vaporization element 80 under the action of negative pressure. The ventilation channel has an air inlet and an air outlet, and external air enters into the ventilation channel through the air inlet and escapes from the air outlet in the form of air bubbles. The first seal member 40 has an air bubble guide part 412 extending toward the liquid storage chamber 221. The air bubble guide part 412 is arranged opposite to the air outlet of the ventilation channel. The air bubble guide part 412 is configured to guide into the liquid storage chamber 221 the air bubbles escaping from the air outlet of the ventilation channel when the electronic vaporization device 100 conducts ventilation, that is, to guide the air bubbles away from the liquid absorbing surface 811 of the vaporization element 80. In this way, the air bubbles escaping from the air outlet of the ventilation channel can be prevented from accumulating on the liquid absorbing surface 811 and blocking the liquid guide opening 2213 and thus the vaporization element 80 can be prevented from dry burning which occurs if the liquid substrate in the liquid storage chamber 221 fails to flow smoothly to the vaporization element 80.
In some embodiments, as shown in FIG. 13 , FIG. 13 shows a schematic cross-sectional diagram of the liquid storage part 20 in a direction. A groove 2231 is formed in the inner wall of the first accommodating chamber 223. The groove 2231 includes a first part 22311 and a second part 22312 communicating with the first part 22311. The first part 22311 is formed on the side wall of the first accommodating chamber 223. The second part 22312 is formed on the partition wall 2212, passes through the hole wall of the liquid guide opening 2213 of the partition wall 2212, and then communicates with the liquid storage chamber 221. The second part 22312 extends non-linearly, thereby increasing the length of the airflow path, which is beneficial for alleviating or preventing the liquid substrate in the liquid storage chamber 221 from leaking from the groove 2231. For example, in some examples, the second part 22312 extends in an L shape, a zigzag shape or an S shape. When the first seal member 40 is installed in the first accommodating chamber 223, the surface of the first seal member 40 elastically abuts against the inner wall of the first accommodating chamber 223, and then the first seal member 40 and the groove 2231 define and form a ventilation channel, and external air enters the ventilation channel through the first part 22311 and escapes from the second part 22312 in the form of air bubbles.
The first seal member 40 is provided with the above-mentioned air bubble guide part 412. Specifically, the air bubble guide part 412 is configured as a flat plate and has a blocking plane 4121 for blocking air bubbles from flowing along the liquid absorbing surface 811. The blocking plane 4121 extends toward the liquid storage chamber 221 in an axial direction and is arranged opposite to an air bubble air outlet 22313. Since the blocking plane 4121 is wider than the air outlet 22313 of the ventilation channel, after the air bubbles escape from the air outlet 22313, under the blocking action of the blocking plane 4121, the air bubbles can only move along the axial direction of the blocking plane 4121 and the air bubbles are guided into the liquid storage chamber 221. That is, the air bubbles are guided away from the liquid absorbing surface 811, thereby preventing the air bubbles from accumulating on the liquid absorbing surface 811 (see the schematic partial enlarged diagram shown in FIG. 14 ). It is easy to understand that in other embodiments of the present disclosure, the air bubble guide part 412 may not be configured as a flat plate as long as the air bubble guide part 412 has the blocking plane 4121 for blocking air bubbles.
In some embodiments, further referring to FIGS. 18 and 19 , the inner wall of the second accommodating chamber 43 a of the first seal member 40 a is provided with a groove 431 a. The groove 431 a includes a first part 4311 a and a second part 4312 a communicating with the first part 4311 a. The first part 4311 a is formed on the side wall of the second accommodating chamber 43 a, and the second part 4312 a is formed on the bottom wall of the second accommodating chamber 43 a. When the porous body 81 of the vaporization element 80 is tightly fitted in the second accommodating chamber 43 a, the above-mentioned ventilation channel can be defined and formed between the porous body 81 and the groove 431 a. External air enters the ventilation channel through an air inlet 43111 of the first part 4311 a and escapes from the ventilation channel through an air outlet 43121 a of the second part 4312 a. In this case, the second part 4312 a is spaced a certain distance from the hole wall of a liquid guide hole 411 a, that is, the second part 4312 a does not communicate with the liquid guide hole 411 a of the first seal member 40 a.
The air bubble guide part 412 a is configured in a cylindrical shape, which extends toward the liquid storage chamber in an axial direction. The air bubble guide part 412 a is provided with an air guide channel 4121 a axially penetrating through the body of the air bubble guide part. Functioning as an air channel, the air guide channel 4121 a communicates with the air outlet port 43121 a of the ventilation channel. In this way, when the electronic vaporization device 100 conducts ventilation, the air can enter the air guide channel 4121 a after escaping from the air outlet port 43121 a of the ventilation channel, and then flow along the air guide channel 4121 a to the liquid storage chamber. The air that escaping from the air guide channel 4121 a is finally released into the liquid storage chamber in the form of air bubbles, thereby achieving the effect of guiding the air bubbles away from the liquid absorbing surface 811.
In some embodiments, further referring to FIGS. 20 and 21 , the groove 431 b is also formed on the inner wall of the second accommodating chamber 43 b of the first seal member 40 b. The groove 431 b also includes a first part 4311 b and a second part 4312 b communicating with the first part 4311 b, the first part 4311 b is formed on the side wall of the second accommodating chamber 43 a, and the second part 4312 b is formed on the bottom wall of the second accommodating chamber 43 b. Unlike the above embodiment, the second part 4312 b communicates with the liquid guide hole 411 b of the first seal member 40 b. That is, the second part 4312 b extends to the hole wall of the liquid guide hole 411 b. The air bubble guide part 412 b extends toward the liquid storage chamber in an axial direction. An air guide groove 4121 b, functioning as an air guide channel, is formed in the surface of the air bubble guide part 412 b. The air guide groove 4121 b communicates with the air outlet port 43121 b of the ventilation channel. Air bubbles can enter the air guide groove 4121 b after escaping from the air outlet port 43121 b of the ventilation channel, and enter the liquid storage chamber along the air guide groove 4121 b, thereby guiding the air bubbles away from the liquid absorbing surface 811. In order to improve the rigidity of the air bubble guide part 412, the air bubble guide part 412 in the all above embodiments can be combined with the hole wall of the liquid guide hole 411.
In other embodiments of the present disclosure, the air bubble guide part 412 may not be arranged on the first seal member 40. For example, as shown in FIG. 15 , the bubble guide part 412 may be formed from the chamber structure 22. Specifically, the chamber structure 22 is provided with a partition plate 224 longitudinally penetrating through the liquid guide opening 2213 and the liquid guide hole 411 and extending to the liquid absorbing surface 811, and two ends of the partition plate are connected to the walls of the liquid guide opening 2213. In this way, the liquid guide opening 2213 is divided into a first part and a second part which are isolated from each other, i.e., two liquid outlets which are isolated from each other. After air bubbles escape from the air outlet port of the ventilation channel, the partition plate 224 can block the flow of the air bubbles along the extending direction of the liquid absorbing surface 811 and guide the air bubbles to flow toward the liquid storage chamber 221 along the longitudinal extending direction of the partition plate 224, thereby guiding the air bubbles away from the liquid absorbing surface 811.
In some embodiments, the electronic vaporization device 100 further includes a bracket Further referring to FIGS. 16 and 17 , FIGS. 16 and 17 show three-dimensional schematic diagrams of the bracket 60 in two directions. The bracket 60 extends in the second shell 30 along an axial direction and has opposite proximal and distal ends. The proximal end extends into the liquid storage part 20 through the distal opening of the liquid storage part 20 and is fixedly connected with the liquid storage part 20. The bracket 60 is provided with a first installation chamber 611 and a second installation chamber 612, the first installation chamber 611 is configured to install the battery cell 61, and the second installation chamber 612 is configured to install an air pressure sensor 62. The electronic vaporization device 100 further includes a main board (not shown) arranged in the second shell 30, the air pressure sensor 62 and the battery cell 61 are both electrically connected to the main board. In order to save manufacturing costs, a plurality of notches 613 are formed in the shell of the bracket 60.
The proximal end of the bracket 60 is provided with a first vent hole 65, a second vent hole 66 and a first electrode hole 67. The distal end of the bracket 60 is provided with an air inlet hole 68 for external air to enter the electronic vaporization device 100. After entering the electronic vaporization device through the air inlet hole 68, the external air enters the liquid storage part 20 through the first vent hole 65. The second vent hole 66 communicates with the second installation chamber 612 for triggering the air pressure sensor 62 in the second installation chamber 612. A trigger air channel 6121 communicating with the second vent hole 66 is formed in the second installation chamber 612. In order to reduce the noise during inhalation, two first vent holes 65 are provided, and the two first vent holes 65 are distributed on two sides of the second vent hole 66, and the two first through holes 65 both have a diameter of 0.6-0.8 mm. In other embodiments of the present disclosure, there may also be one first vent hole 65. Compared with the arrangement of two first vent holes 65, the arrangement of one first vent hole can provide a large diameter and it is easy to make noise during inhalation. If two or more vent holes are provided, the diameter of the first vent holes may be made smaller, thereby alleviating the noise generated during inhalation.
The electronic vaporization device 100 further includes a conductive terminal 64 electrically connected to the battery cell 61. The conductive terminal 64 extends into the first electrode hole 67. The conductive terminal 64 is electrically connected to a conductive electrode 83 of the vaporization element 80, so that the battery cell 61 provides electric energy to the heating element 821 of the vaporization element 80. The air pressure sensor 62 is configured to sense the air pressure change during the inhalation of the user and send a sensing signal to the main board, and the main board controls the battery cell to provide electric energy to the vaporization element 80 according to the air pressure change.
Further, the electronic vaporization device 100 further includes a third seal member 90 which is made of flexible silicone or rubber. The third seal member 90 is fitted over the proximal end of the bracket 60 and in interference fit with the inner wall of the liquid storage part 20, thereby sealing the assembly gap between the bracket 60 and the liquid storage part 20. There is a gap between the first seal member 90 and the vaporization surface 82 of the vaporization element 80, and the gap is configured to form the vaporization chamber 84 of the electronic vaporization device 100. The aerosol generated by heating the liquid substrate by the vaporization element 80 is released here in this gap and escapes from the liquid storage part 20 through the above-mentioned first airflow channel 2221 and second airflow channel 2222, then enters the first shell 10, and finally escapes from the electronic vaporization device 100 through the air outlet hole 12 of the first shell 10. It is easy to understand that the first seal member 90 is provided with a second electrode hole (not shown) and a third vent hole 91. The conductive electrode 83 of the vaporization element 80 extends into the first electrode hole 67 through the second electrode hole, so as to be electrically connected with the conductive terminal 64. The first vent hole 65 communicates with the third vent hole 91. After escaping from the first vent hole 65, the external air enters the vaporization chamber 84 through the third vent hole 91, and then flows to the air outlet hole 12 through the first airflow channel 2221 and the second airflow channel 2222, see the air flow path shown by the arrow route R1 in FIG. 3 . The third vent hole 91 is opposite to the second vent hole 66, so that the air pressure sensor can be triggered better. When the user inhales, the second installation chamber 612 generates a negative pressure, and the air pressure sensor 62 can sense the air pressure change in the second installation chamber 612, and then generate an induction signal, and send the induction signal to the main board. The main board then controls the electronic vaporization device 100 to work.
