FIG. 1 shows an electronic atomization device 1 in some embodiments of the invention. The electronic atomization device 1 can be used to inhale an aerosol and can include an atomizer 100 and a power supply 200 electrically connected to the atomizer 100 . A power supply 200 is used to supply electricity to the atomizer 100 . Further, the atomizer 100 is used to accommodate a liquid substrate and to atomize the liquid substrate by heating to generate an aerosol after energization. The atomizer 100 is installed vertically above the power supply 200 and is connectable to the power supply 200 in a removable or non-removable manner.

As shown in FIG. 2, the atomizer 100 in the first embodiment of the present invention can include a liquid storage case 10 and a heating module 20 housed in the liquid storage case 10. As shown in FIG. A liquid storage chamber 110 for storing a liquid substrate and an exhaust path 120 for discharging aerosol are formed in the liquid storage case 10 . The exothermic module 20 includes a base module 30 , an atomizing core 40 and an exothermic base module 50 . The atomizing core 40 is housed in the space formed between the base module 30 and the heat-generating base module 50 . The atomization core 40 communicates with the liquid storage chamber 110 to guide the liquid, and communicates with the exhaust path 120 to guide the gas, and atomizes the liquid substrate adsorbed from the liquid storage chamber 110 by heating. Used to generate aerosols. An atomization chamber 420 is formed between the base module 30 and the atomization core 40 to achieve aerosol-air mixing.

Specifically, the liquid storage case 10 may include a housing 11 with an open bottom end and an exhaust pipe 12 installed in the housing 11 in the vertical direction. The housing 11 has a tubular shape, and its cross section can be approximately an elongated elliptical shape, a track shape, or the like. An annular liquid storage chamber 110 is defined between the inner wall surface of the housing 11 and the outer wall surface of the exhaust pipe 12 .

The exhaust pipe 12 is connected to the inside of the ceiling wall of the housing 11 and can be installed coaxially with the housing 11 . An inner wall surface of the exhaust pipe 12 defines an exhaust path 120 . In this embodiment, the exhaust pipe 12 and the housing 11 are integrally molded, for example, by injection molding. Also, in other embodiments, the exhaust pipe 12 and the housing 11 may be assembled after being molded separately.

As shown in FIGS. 2 to 7, the atomization core 40 includes a liquid absorber 41 and a heating element 42 installed on the liquid absorber 41. As shown in FIGS. The liquid absorber 41 communicates with the reservoir chamber 110 in a liquid guiding manner and is used to draw a liquid substrate from the reservoir chamber 110 and transfer the liquid substrate to the heating element 42 . The heating element 42 is electrically connected to the power supply device 200, and is used to generate aerosol by heating and atomizing the liquid substrate adsorbed from the liquid absorbent 41 after being energized to generate heat.

The absorbent 41 can be made of a material having a porous capillary structure, such as porous absorbent ceramics and absorbent cotton. The liquid absorbent 41 has a liquid absorbent surface 411 and a heat generating surface 412 . The heat generating surface 412 is used for mounting the heat generating element 42 . The liquid absorption surface 411 is used to absorb the liquid substrate from the liquid storage chamber 110 and transfer the liquid substrate to the heating surface 412 by the porous capillary structure inside the liquid absorption 41 . Specifically, in this embodiment, the liquid-absorbent 41 is bowl-shaped porous liquid-absorbent ceramics. The liquid absorbing surface 411 is located on the side of the liquid absorbing 41 facing the liquid storage chamber 110 , and the heat generating surface 412 is located on the side of the liquid absorbing 41 opposite to the liquid storage chamber 110 . The heating element 42 is installed on the heating surface 412 . That is, the heating element 42 is installed on the side of the liquid absorbent 41 facing the base module 30 .

The base module 30 may include a base 31 and electrode rods 33 longitudinally inserted into the base 31 . The base 31 is fitted into the opening at the lower end of the housing 11 to hermetically seal the opening at the lower end of the housing 11 . The base 31 has a plate-shaped main body 311, a cylindrical side wall 312 extending upward from the outer periphery of the main body 311, and two spaces extending upward from the upper end surface of the main body 311. A support arm 314 may be included. The two support arms 314 can be located on two opposite longitudinal sides of the main body 311 and can be used to engage the heat generating base 52 . Further, the upper end surface of the main body portion 311 and the inner wall surface of the cylindrical side wall 312 define the liquid storage space 3120 . The reservoir space 3120 may accumulate some condensate, further reducing liquid leakage.

Further, the base 31 further includes an intake boss 313 extending upward from the top surface of the main body 311 . The intake boss 313 is installed in the cylindrical side wall 312 , and the outer wall surfaces on both sides in the width direction can be integrally connected to the inner wall surfaces on both sides in the width direction of the cylindrical side wall 312 . Further, in order to allow outside air to enter the atomization chamber 420, a plurality of small air intake holes 3130 are formed by recessing the ceiling surface of the air intake boss 313 downward. The plurality of air intake small holes 3130 may be distributed in an array. As a result, a sufficient amount of air intake is guaranteed, and the surface tension film formed in the plurality of air intake small holes 3130 can further reduce liquid leakage. In addition, by forming the air intake small hole 3130 in the air intake boss 313, the end surface of the upper end of the air intake small hole 3130 is higher than the bottom surface of the liquid storage space 3120, so the risk of liquid leakage from the air intake small hole 313 is further reduced. Let me.

Further, the plurality of air intake pores 3130 may include a number of first air intake pores 3131 and a number of second air intake pores 3132 surrounding the outside of the first air intake pores 3131 . Some of the first air intake small holes 3131 and some of the second air intake small holes 3132 are arranged in an array to form a ring (for example, an annular ring, an elliptical ring, a square ring, or a polygonal ring). It should be distributed at intervals. Also, the number of the first small air intake holes 3131 should be less than the number of the second small air intake holes 3132 . In some embodiments, the number of first air inlet holes 3131 may be 3-6 and the number of second air inlet holes 3132 may be 6-15. In this embodiment, there are four first intake small holes 3131 . Moreover, the four first air intake small holes 3131 are uniformly and symmetrically distributed along the center of the air intake boss 313 . It also has ten second air intake small holes 3132 . Moreover, the ten second air intake small holes 3132 are uniformly and symmetrically distributed along the center of the air intake boss 313 .

The first air intake small hole 3131 and the second air intake small hole 3132 have different air intake cross-sectional areas. The unequal cross-section configuration of the plurality of inlet apertures 3130 reduces aerodynamic noise. Furthermore, in this embodiment, the intake cross-sectional area of the first intake small hole 3131 is smaller than the intake cross-sectional area of the second intake small hole 3132 . In addition, the first small air intake holes 3131 and the small second air intake holes 3132 are distributed in an annular array. That is, in this embodiment, the structural form of the air intake small hole 3130 is a form of "a large hole in the outer periphery and a small hole in the center". Some of the first air intake holes 3131 located on the inner periphery have a small air intake cross-sectional area, which can effectively reduce the leakage of condensate. In addition, since the intake cross-sectional area of some of the second intake small holes 3132 located on the outer periphery is large, it is possible to ensure sufficient intake area and appropriate intake resistance by balancing the intake resistance and noise.

An intake hole 3110 may be formed in the lower end surface of the main body portion 311 by further recessing upward. Air intake holes 3110 extend longitudinally. Further, the upper end of the air intake hole 3110 communicates with the lower ends of the plurality of small air intake holes 3130 so as to form an air intake path 315 that allows outside air to enter the atomization chamber 420 . Furthermore, the intake cross-sectional area of the intake hole 3110 is greater than the sum of the intake cross-sectional areas of the plurality of intake small holes 3130 .

The main body portion 311 is further provided with an electrode through hole 3111 for inserting the electrode rod 33 . Two electrode rods 33 are normally provided, and the two electrode rods 33 are electrically connected to the two poles of the heating element 42 respectively. The end surface of the upper end of the electrode rod 33 is in contact with the heating element 42 and conducts. In addition, the electrode rod 33 also plays a role of supporting the atomization core 40 . Also, two electrode through holes 3111 are provided correspondingly. The two electrode rods 33 are vertically inserted into the two electrode through holes 3111 respectively. In the present embodiment, the two electrode through-holes 3111 are positioned inside the cylindrical side wall 312 and can be positioned on both sides of the intake boss 313 in the longitudinal direction. Furthermore, the end surface of the upper end of each electrode through-hole 3111 should be higher than the bottom surface of the liquid storage space 3120 so as to reduce the risk of liquid leakage from the electrode through-hole 3111 .

In some embodiments, the atomizer 100 may further include a stationary cover 60 . The fixed cover 60 covers the outside of the base 31 and covers the lower end of the housing 11 to fix the base 31 . Furthermore, the fixed cover 60 can be hook-connected to the housing 11 . Thereby, the fixed cover 60 and the housing 11 are fixed. A metal material may be used for the fixed cover 60 . Since the metal material undergoes little thermal expansion and contraction deformation when the temperature changes, the fixation between the parts of the atomizer 100 is more stable and reliable, and the sealing performance is improved. In addition, the fixed cover 60 made of metal can also be used for magnetic attraction connection with the power supply device 200 . As can be appreciated, in other embodiments, the fixed cover 60 may not be provided, and the base 31 and the housing 11 may be fixed together by means of hook connection, screw connection, interference fit connection, or the like.

Furthermore, as shown in FIGS. 3-6 and 9, the base module 30 further includes a sealing member 32 overlying the outside of the base 31 . The sealing member 32 is hermetically installed between the inner wall surface of the housing 11 and the outer wall surface of the base 31 . The sealing member 32 can be integrally molded of a resilient material such as silicone. The sealing member 32 is installed between the body portion 321, two fitting portions 322 respectively extending upward from two opposite sides of the body portion 321, and another two opposite sides of the body portion 321. A boss portion 323 may be included. The body portion 321 has an annular shape and is disposed between the outer wall surface of the cylindrical side wall 312 and the inner wall surface of the housing 11 in a sealed manner. Since the outer peripheral surface of the body portion 321 can be tightly fitted to the inner peripheral surface of the bottom end of the housing 11, the sealing performance is further improved.

The two fitting portions 322 are formed by extending upward from outer edges on both sides in the longitudinal direction (longitudinal direction) of the main body portion 321 . The two fitting portions 322 are respectively covered on both sides of the heat-generating base 52 and are capable of restricting the position of the sealing member 32 in the longitudinal direction. This prevents mounting distortion in the longitudinal direction of the sealing member 32 . The two fitting portions 322 occupy only the space in the housing 11 along the longitudinal direction and do not occupy the space in the housing 11 in the lateral direction. Therefore, this structure is advantageous for realizing a lightweight and thin design of the atomizer 100 .

The outer wall surfaces on both sides of the boss portion 323 are integrally joined to the inner wall surfaces on both sides of the body portion 321 in the short direction (width direction). The boss portion 323 is fitted into the bottom portion of the heat-generating base 52 and can restrict the position of the sealing member 32 in the lateral direction. This prevents the sealing member 32 from being distorted in the transverse direction.

The boss portion 323 is formed with at least one air intake through-hole 3230 that communicates with a plurality of small air intake holes 3130 and the atomization chamber 420 along the vertical direction. In this embodiment, one intake through-hole 3230 is provided. In addition, the one intake through-hole 3230, the boss portion 323, and the body portion 321 are coaxially installed. As can be appreciated, in other embodiments, the number of air intake through-holes 3230 is not limited to one and may not be coaxial with the boss portion 323 and/or body portion 321 . The boss portion 323 is positioned above the plurality of air intake small holes 3130 . When liquid splashes occur on the heat generating surface 412 of the liquid absorber 41, the boss portion 323 can block part of the splashed liquid droplets from directly splashing onto the surface of the air intake small holes 3130, thereby reducing liquid leakage. do. Also, when the inhalation is stopped, the vapor flows back due to the action of the negative pressure. However, most of the backflowing vapor does not come into direct contact with the air intake small holes 3130 due to the action of the boss portion 323 . This reduces the formation of condensate in the inlet ostium 3130, thereby reducing the risk of leakage.

The intake through hole 3230 may include an intake section 3231 communicating with the plurality of intake pores 3130 and an exhaust section 3232 communicating with the atomizing chamber 420 . In this embodiment, the intake through hole 3230 has a contracted shape. That is, the cross-sectional area of the intake section 3231 is larger than the cross-sectional area of the exhaust section 3232 . The intake through-hole 3230, which has a contracted shape, allows the airflow to be focused during inspiration. As a result, the flow velocity increases, so the aerosol in the atomization chamber 420 is rapidly discharged along with the airflow. When inhalation is stopped, the negative pressure causes the vapor to flow backwards. However, since the flow velocity of the vapor decreases when heading from the exhaust section 3232 to the intake section 3231, the backflow of the vapor can be reduced. In addition, since the cross-sectional area of the upper exhaust section 3232 is small, the condensate is less likely to leak, thereby reducing liquid leakage. Furthermore, the cross-sectional area of the exhaust port portion at the upper end of the exhaust section 3232 (one end spaced apart from the intake section 3231 ) may be smaller than the cross-sectional area of the intake boss 313 .

In order to further reduce liquid leakage, the upper end face of the exhaust section 3232 (one end face facing the atomization chamber 420) should be higher than the upper end face of the boss portion 323 around it. Further, the intake section 3231 and the exhaust section 3232 may be connected by a curved surface so as to make a smooth transition. As a result, it is possible to reduce the resistance force of the airflow at the connection point between the intake section 3231 and the exhaust section 3232, avoiding the generation of eddy currents at the connection point, thereby effectively reducing airflow noise.

The cross-sectional shapes of the intake section 3231 and the exhaust section 3232 may be the same or different. In this embodiment, the cross-sectional shape of the intake section 3231 is circular. In addition, the hole diameter of the intake section 3231 gradually decreases from bottom to top (from one end away from the exhaust section 3232 to one end close to the exhaust section 3232). The exhaust section 3232 is a straight through hole with a track-shaped cross section. That is, both the length of the major axis and the length of the minor axis of the exhaust section 3232 are constant in the vertical direction. The intake section 3231 and the exhaust section 3232 are connected via a connection section 3233 so as to have a smooth transition. The connection section 3233 has a first end communicating with the intake section 3231 and a second end communicating with the exhaust section 3232 . The cross-sectional shape and size of the first end match the cross-sectional shape and size of the upper end of intake section 3231 . Also, the cross-sectional shape and size of the second end match the cross-sectional shape and size of the lower end of the exhaust section 3232 . The cross-sectional shape of the connecting section 3233 gradually changes from circular at the first end to track-shaped at the second end. As can be appreciated, in other embodiments, the cross-sectional shape of intake section 3231 and exhaust section 3232 may be circular, elliptical, square, or other shapes.

The boss portion 323 is further provided with two electrode holes 3236 for inserting the two electrode rods 33 respectively. The two electrode holes 3236 can be positioned on both longitudinal sides of the intake through-hole 3230 . The sealing member 32 is further formed with two retraction holes 3210 corresponding to the two support arms 314 respectively. The two support arms 314 can be respectively inserted into the two retraction holes 3210 and engaged with the heat generating base 52 . Specifically, the extension length in the length direction of the boss portion 323 is smaller than the extension length in the length direction of the main body portion 321 . The two evacuation holes 3210 are respectively formed between the outer wall surfaces on both sides in the length direction of the boss portion 323 and the inner wall surfaces on both sides in the length direction of the main body portion 321 .

In addition, the ceiling surface of the boss portion 323 is recessed downward and/or the bottom surface of the boss portion 323 is recessed upward to form several guiding grooves 3234 . The several guide grooves 3234 communicate the intake through hole 3230 and the two electrode holes 3236 with the evacuation hole 3210 . The guiding groove 3234 has a fine groove structure and can have a strong capillary force with respect to a liquid substrate. Therefore, under the action of capillary force, the leaked liquid from the intake through hole 3230 and the two electrode holes 3236 is adsorbed, and by guiding the leaked liquid to the evacuation hole 3210, the liquid is stored via the evacuation hole 3210. Being dropped into space 3120 further reduces liquid leakage.

As shown in FIGS. 3-6 and 10-11, heat generating base module 50 includes heat generating base 52 . A heat generating base 52 is engaged and connected to the base 31 to secure the atomizing core 40 . In this embodiment, both the heating base 52 and the base 31 are made of plastic material, and the heating base 52 and the base 31 are hooked on each other.

At least one liquid supply hole 520 is formed in the heat generating base 52 to communicate the liquid absorption 41 with the liquid storage chamber 110 . The liquid substrate in the liquid storage chamber 110 can be supplied to the liquid absorption surface 411 of the liquid absorption 41 through the at least one liquid supply hole 520 . Atomization core 40 can be housed in heating base 52 . The side wall of the heating base 52 is further formed with at least one opening 527 that exposes at least a part of the side surface of the liquid absorbent 41 . This embodiment has two liquid supply holes 520 . The two liquid supply holes 520 are located on both sides of the heating base 52 in the length direction. It also has two openings 527 . The two openings 527 are located on both sides of the heat generating base 52 in the width direction.

Furthermore, at least one liquid storage ventilation structure 521 is further formed on the outer surface of the heating base 52 . The at least one reservoir ventilation structure 521 communicates with the reservoir chamber 110 and can be used to balance the air pressure within the reservoir chamber 110 . If the air pressure in reservoir 110 drops too low, ambient air can enter reservoir 110 through reservoir ventilation structure 521 . This avoids a situation in which the supply of liquid is delayed due to an excessive decrease in the pressure in the liquid storage chamber 110, thereby preventing the occurrence of dry heating.

Specifically, this embodiment has two liquid storage ventilation structures 521 . Two liquid storage and ventilation structures 521 are respectively formed on both longitudinal sides of the heating base 52 . Moreover, the two liquid storage and ventilation structures 521 can be installed so as to be rotationally symmetrical with respect to the central axis of the heating base 52 .

Each of the liquid storage and ventilation structures 521 has a ventilation path 522 formed at one end of the heating base 52 close to the liquid storage chamber 110 and a liquid storage path 522 formed at one end of the heat generation base 52 away from the liquid storage chamber 110. It includes a groove 524 and a tension blocking groove 526, a liquid suction groove port 523 that communicates the ventilation path 522 and the liquid storage groove 524, and a ventilation inlet 525 that communicates the ventilation path 522 and the tension blocking groove 526. One end of the ventilation path 522 communicates with the liquid storage chamber 110, and the other end communicates with the liquid storage groove 524 and the tension blocking groove 526 via the liquid suction groove port 523 and the ventilation inlet 525, respectively. Ventilation inlet 525 is used to bring outside air into ventilation path 522 . In addition, the liquid absorption groove 523 can absorb a liquid substrate (e.g., condensate or leak in the ventilation path 522, condensate or leak formed on the atomization core 40, or at other sites) by capillary force. formed condensate or leak) into the reservoir groove 524. This prevents blockage of the ventilation path 522 by liquid substrates by separating ventilation and storage. In addition, the width of the ventilation inlet 525 is larger than the width of the liquid absorption groove 523 so that a greater capillary force is formed in the liquid absorption groove 523 . As a result, the liquid substrate in the ventilation path 522 is sucked into the liquid storage groove 524 via the liquid absorption groove port 523, thereby realizing gas-liquid separation.

Specifically, the ventilation path 522 includes several ventilation grooves 5221 extending in the circumferential direction of the heating base 52, an air guide groove 5222 communicating with the several ventilation grooves 5221 and extending in the longitudinal direction, and an air guide groove. It includes a laterally extending return air groove 5223 in communication with 5222 . The plurality of ventilation grooves 5221 can be formed by recessing the outer peripheral surface of one end of the heating base 52 close to the liquid storage chamber 110 inward. And the several ventilation grooves 5221 can be arranged in parallel and spaced apart. Further, the air guide groove 5222 is formed by recessing the side surface of the heat generating base 52 inward. One end of the air guide groove 5222 communicates with the uppermost ventilation groove 5221 , and the other end extends upward to the ceiling surface of the heating base 52 . The return air groove 5223 is formed by recessing the ceiling surface of the heating base 52 downward. One end of the return air groove 5223 communicates with the air guide groove 5222, and the other end communicates with the liquid supply hole 520 on the corresponding side.

The ventilation grooves 5221, the air-conducting grooves 5222, and the air-returning grooves 5223 all have a minute fine groove structure, which does not impede the flow of gas, but can impede the flow of the liquid substrate. This ensures that the ventilation path 522 has the function of ventilation and liquid isolation, thus reducing the risk of the liquid substrate in the reservoir 110 leaking through the ventilation path 522 . In some embodiments, the ventilation groove 5221, the air introduction groove 5222, and the return air groove 5223 may have a width of 0.3-0.6 mm and a depth of 0.3-0.6 mm.

The liquid storage groove 524 includes a plurality of sub-storage grooves 5241 extending in the circumferential direction of the heating base 52 . The plurality of sub-liquid storage grooves 5241 can be formed by recessing inward the outer peripheral surface of one end of the heating base 52 that is spaced apart from the liquid storage chamber 110 . In addition, the plurality of sub-liquid storage grooves 5241 can be arranged in parallel and spaced apart. Furthermore, both ends of each sub-storing groove 5241 in the circumferential direction extend to two openings 527 and can communicate with the two openings 527 respectively. Thereby, the sub-liquid storage groove 5241 and the liquid absorption 41 are made to communicate with each other. After the condensate has accumulated in the liquid storage groove 524 (or the liquid substrate has leaked from the ventilation path 522 to the liquid storage groove 524), the capillary force of the gap between the liquid absorption 41 and the liquid storage groove 524 causes the condensation to occur. Liquid (or liquid substrate) is sucked into the liquid absorber 41 . Thus, the risk of condensate backflowing from ventilation path 522 into reservoir chamber 110 and leaking into power supply 200 is reduced.

Since the sub-liquid storage groove 5241 has a fine narrow groove structure and has a strong capillary force with respect to a liquid substrate, the condensed liquid in the ventilation groove 5221 can be adsorbed by the action of the capillary force. In some embodiments, the sub-storage groove 5241 may have a width of 0.3-0.6 mm and a depth of 0.3-0.6 mm.

The strain relief groove 526 has a wider width than the ventilation channel 522 and the reservoir groove 524 so that the condensate in the reservoir groove 524 flows back into the reservoir chamber 110 causing the pressure in the reservoir chamber 110 to fluctuate. It is used to further stabilize the ventilating pressure, preventing situations in which this would affect the fluid supply. The tension blocking groove 526 may be extended in the longitudinal direction, and the lower end can communicate with the lowest sub-storage groove 5241, and the upper end communicates with the uppermost sub-storage groove 5241. communicate. As a result, the plurality of sub-liquid storage grooves 5241 are communicated with each other through the tension blocking grooves 526 . The width of the tension relief grooves 526 may be greater than the width of the ventilation inlets 525 . In some embodiments, the tension relief grooves 526 may have a width of 1-3 mm and a depth of 0.5-1.2 mm.

The liquid suction groove 523 and the ventilation inlet 525 can communicate with both circumferential sides of one end of the ventilation path 522 that is separated from the liquid storage chamber 110 . In some embodiments, the ventilation inlet 525 can communicate with one of the number of ventilation grooves 5221 and the liquid inlet 523 can communicate with another of the number of ventilation grooves 5221. be. Specifically, in this embodiment, the plurality of ventilation grooves 5221 includes a first ventilation groove 5224 located at the bottom and a first ventilation groove 5224 located above the first ventilation groove 5224 and adjacent to the first ventilation groove 5224. may include a second ventilation groove 5225 for The upper end of the liquid absorption groove 523 can communicate with one side of the first ventilation groove 5224 in the circumferential direction, and the lower end of the liquid absorption groove 523 extends downward to the uppermost one of the liquid storage grooves 5241 in the longitudinal direction. can be communicated with the sub-liquid storage groove 5241. The ventilation inlet 525 has an upper end that can communicate with the other circumferential side of the second ventilation groove 5225 and a lower end that extends downward in the longitudinal direction until it communicates with the upper end of the tension blocking groove 526 . As shown by the arrows in FIG. 11, after entering the second ventilation groove 5225 from the ventilation inlet 525, the air passes through several ventilation grooves 5221 located above the second ventilation groove 5225 in order. By flowing to the groove 5222 and finally entering the liquid storage chamber 110 via the return air groove 5223, the air pressure in the liquid storage chamber 110 is balanced. In some embodiments, the width of the liquid absorption groove 523 may be 0.3-0.6 mm, and the depth may be 0.3-0.6 mm. Also, the width of the ventilation inlet 525 may be 0.6 to 1.5 mm, and the depth may be 0.3 to 0.6 mm.

As can be appreciated, in other embodiments, the ventilation inlet 525 and the wicking groove 523 may communicate with the same ventilation groove 5221 . Also, the ventilation inlet 525 and the liquid suction groove 523 may communicate with both circumferential ends of the one ventilation groove 5221 (for example, the first ventilation groove 5224).

During the inhalation process, liquid substrate is drawn from reservoir 110 into ventilation channel 522 , and the liquid substrate must resist surface tension as it is drawn to ventilation inlet 525 . At this time, the ventilation inlet 525 plays the role of preventing the liquid substrate from being sucked out from the ventilation channel 522, and one first ventilation groove 5224 located at the bottom absorbs part of the liquid substrate. FIG. 12 shows a gas-liquid two-phase distribution map within the liquid storage ventilation structure 521 at the time of stopping inhalation. The test conditions were 3 seconds of inhalation and 27 seconds of stopping. As is clear from the gas-liquid two-phase distribution diagram, when the inhalation is stopped, the liquid phase (mainly what leaked from the liquid storage chamber 110 in the inhalation process) is mainly distributed in the ventilation path 522, and the liquid is stored. The liquid phase distribution in the grooves 524 was slight, or almost no liquid phase distribution was observed. As a result, the outflow of the liquid substrate from the ventilation path 522 could be well prevented.

Further, as shown in FIGS. 4 to 6 again, the heat generating base module 50 further includes a sealing cover 53 that covers the upper portion of the heat generating base 52, a heat generating base 52 that is housed in the heat generating base 52, and a liquid absorbent. It includes a gasket 51 placed between 41 . Both the sealing cover 53 and gasket 51 can be made of a resilient material such as silicone. Gasket 51 may be in the form of an annular sheet. The gasket 51 is tightly abutted between the heat-generating base 52 and the liquid absorbing member 41 in a hermetically sealed manner, and can play a role of buffering, ensuring sealing performance, and preventing liquid leakage. The sealing cover 53 is placed on the upper portion of the heating base 52 to seal the lower end of the liquid storage chamber 110 and to hermetically separate the atomization chamber 420 and the liquid storage chamber 110 . Since the outer peripheral surface of the sealing cover 53 can be tightly fitted to the inner peripheral surface of the housing 11, the sealing performance is further improved. A ventilation hole 530 may be formed in the ceiling surface of the sealing cover 53 by further recessing downward. The lower end of the exhaust pipe 12 can be fitted in the ventilation hole 530 . By sealingly engaging the outer peripheral surface of the lower end of the exhaust pipe 12 with the hole wall of the vent hole 530, the exhaust path 120 and the liquid storage chamber 110 are separated in a sealing manner.

FIG. 14 shows a heat generating module in some implementations of the prior art. The exothermic module includes an atomizing top base 115 , an atomizing core 12 and an atomizing bottom base 116 . A ventilation groove 112 is installed on the outer surface of the atomizing top base 115 . The ventilation groove 112 includes a first sub-ventilation groove 1121 and a second sub-ventilation groove 1122 . A discharge groove 114 and a liquid storage groove 113 are installed on the outer surface of the atomization bottom base 116 . One end of the discharge groove 114 communicates with the ventilation groove 112 , and the other end of the discharge groove 114 communicates with the liquid storage groove 113 . Reservoir groove 113 includes a plurality of sub-reservoir grooves 1131 .

Figures 13 and 15 show graphs of the ventilation pressure for the heat generating modules shown in Figures 3 and 14, respectively. The horizontal axis in the figure is the suction time, and the vertical axis is the pressure in the liquid storage chamber. In the test experiment, the test conditions were inhalation 3s, stop 27s, and power 6W. The heat generating module shown in FIG. 3 had four ventilation grooves 5221, and each ventilation groove 5221 had a width of 0.35 mm and a depth of 0.4 mm. The width of the ventilation inlet 525 was 1 mm and the depth was 0.4 mm, and the width of the tension blocking groove 526 was 2 mm and the depth was 0.8 mm. The heat generating module shown in FIG. 14 had four second sub-ventilation grooves 1122, and each second sub-ventilation groove 1122 had a width of 0.35 mm and a depth of 0.4 mm. The width of the inlet of one end of the discharge groove 114 that communicates with the second sub-ventilation groove 1122 was 0.6 mm, and the depth was 0.4 mm. As is clear from FIGS. 13 and 15, the heat-generating module shown in FIG. , the ventilation rate was high). On the other hand, the exothermic module shown in FIG. 14 had a wider range of ventilation pressure fluctuations, and most ventilated once per two openings (that is, the ventilation time was long and the ventilation rate was slow). By comparison, the exothermic module shown in FIG. 3 had higher ventilation stability. Also, during ventilation, it had a short ventilation path without passing through the first ventilation groove 5224 located at the bottom, so it had a small ventilation pressure and a high ventilation speed. As a result, it was possible to effectively avoid situations such as the occurrence of a burning smell and a decrease in the amount of vapor due to poor ventilation.

Figure 16 shows the base 31 in a first alternative of the invention. The main differences between this scheme and the first embodiment are as follows. In this embodiment, the intake cross-sectional area of the first intake small hole 3131 is larger than the intake cross-sectional area of the second intake small hole 3132 . That is, the structural form of the intake small hole 3130 is a form of "a small hole in the outer periphery and a large hole in the center".

FIG. 18 shows the base 31 in some prior art embodiments. In the base 31 , the intake cross-sectional area of the first intake small hole 3131 is equal to the intake cross-sectional area of the second intake small hole 3132 .

Figures 8, 17 and 19 show the distribution diagrams of the noise simulations based on Figures 7, 16 and 18, respectively. In test experiments, the bases shown in FIGS. 7, 16, and 18 all contained four primary air inlet holes 3131 and ten secondary air inlet holes 3132. As shown in FIG. In FIG. 7, the hole diameter of the first air intake small hole 3131 was 3.5 mm, the hole diameter of the second air intake small hole 3132 was 4.5 mm, and the maximum aerodynamic noise was 61.37 dB. In FIG. 16, the hole diameter of the first air intake small hole 3131 was 4.5 mm, the hole diameter of the second air intake small hole 3132 was 3.5 mm, and the maximum aerodynamic noise was 66.52 dB. In FIG. 18, the hole diameters of the first air intake small hole 3131 and the second air intake small hole 3132 were both 3.5 mm, and the maximum aerodynamic noise was 70.83 dB. As is clear from FIGS. 8, 17, and 19, the air intake small hole structure in which large and small holes are alternately installed as shown in FIGS. 7 and 16 clearly reduces the aerodynamic noise during intake. was made. On the other hand, the intake small hole structure shown in FIG. 18 produced a large amount of aerodynamic noise. In addition, in the case of the air intake small hole structure having a large hole in the outer periphery and a small hole in the center shown in FIG. . Therefore, when designing, the intake cross-sectional area of the first small intake hole 3131 should be made smaller than the intake cross-sectional area of the second small intake hole 3132 . By selecting an appropriate number and size (e.g., hole diameter, intake cross-sectional area, etc.) of the first intake small holes 3131 and the second intake small holes 3132, the aerodynamic noise during operation of the atomizer 100 is less than 61.4 dB. Become.

Figures 20-21 show the base 31 in a second alternative of the invention. The main differences between this scheme and the first embodiment are as follows. In this embodiment, the upper surface 3133 of the intake boss 313 has a projecting shape. Specifically, the upper surface 3133 may form a spherical surface. A plurality of air intake holes 3130 on the air intake boss 313 extend downward from the upper surface 3133 . Also, in other embodiments, the top surface 3133 may have other shapes, such as frusto-conical. Also, the second air intake small holes 3132 located on the outer circumference can be installed so as to be close to the outer edge of the upper surface 3133 .

As shown in FIG. 22, by designing the air intake boss 313 in an overhanging shape with a small hole on the inside and a large hole on the outside, the film boundary 35 of the condensate formed at the second air intake small hole 3132 portion on the outer circumference is , has a substantially spherical shape and can communicate with the condensate accumulated in the liquid storage space 3120 . This causes the condensate to tend to flow outside of the inlet ostium 3130 . The direction of flow of the condensate is as indicated by the arrows in FIG. When the air intake small holes 3130 are covered with condensate, the central first air intake small holes 3131 have a small hole diameter, so the condensate is less likely to flow out. On the other hand, the condensate in the second air intake small holes 3132 on the outer circumference communicates with the condensate accumulated in the base 31, and is easily discharged by the condensate accumulated in the base 31, so that the liquid storage space of the base 31 3120 can spread quickly. As described above, the intake small hole 3130 is not easily blocked.

Figure 23 shows the sealing member 32 in a third alternative of the invention. The main differences between this scheme and the first embodiment are as follows. In this embodiment, the boss portion 323 is not provided with the electrode hole 3236 . In addition, a retraction groove 3235 that communicates with the retraction hole 3210 is formed by recessing both sides of the boss portion 323 in the longitudinal direction. This structure reduces the impact on the shape and size of the intake through-hole 3230 design.

Figure 24 shows the sealing member 32 in a fourth alternative of the invention. The main differences between this scheme and the first embodiment are as follows. In this embodiment, the boss portion 323 is not provided with the electrode hole 3236 . This structure reduces the impact on the shape and size of the intake through-hole 3230 design.
