CROSS REFERENCE TO RELATED APPLICATIONS

The present application claims the benefits of priorities from the China Patent Application No. 202010019529.3 filed on 8 January 2020, the China Patent Application No. 202020038013.9 filed on 8 January 2020, and the China Patent Application No. 202010537925.5 filed on 12 June 2020.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This application generally relates to an electronic device, and specifically, to a vaporization device for providing an inhalable aerosol.

2. Description of the Related Art

With the increasingly strict regulations and restrictions on tobacco products in various regions and governments around the world, people's demands for tobacco substitutes also continue to grow. An electronic cigarette device may be a tobacco substitute, which uses an electronic aerosol generation device or an electronic vaporization device to vaporize a vaporizable material (for example, e-liquid) to generate an aerosol for inhalation by a user, thereby achieving a sensory experience of simulated smoking. With respect to traditional tobacco products, the electronic cigarette device as the substitute can effectively reduce harmful substances generated by combustion, thereby reducing harmful side effects of smoking.

For an existing electronic cigarette product, a pressure balance of a liquid storage compartment is not considered. In the existing electronic cigarette product, the liquid storage compartment is generally designed to be completely sealed to prevent a vaporizable solution from overflow. During transport, pressure in a liquid storage compartment of a manufactured electronic cigarette product may be increased due to a temperature change or a pressure change. The increase of the pressure in the liquid storage compartment causes a great amount of e-liquid to flow toward an aerosol generation component, and may cause an e-liquid leakage problem to the electronic cigarette product. In addition, with continuous use of the electronic cigarette product by a user, a vaporizable solution in the liquid storage compartment is continuously consumed and decreased, so that the pressure in the liquid storage compartment is decreased to form a negative pressure. The negative pressure causes the vaporizable solution in the liquid storage compartment to be difficult to uniformly flow onto the aerosol generation component, so that the aerosol generation component does not uniformly adsorb the vaporizable solution. In this case, when the temperature increases, there is a high probability for the aerosol generation component to burn out and generate a burnt smell, causing bad user experience.

Therefore, a vaporization device which can resolve the above problem is provided in this disclosure.

A storage compartment 30 is defined among the cartridge housing 1, the tube 1t, and the upper cap sealing member 2. The storage compartment 30 may store e-liquid. A part of the tube 1t extends into the opening 3h1 of the upper cap 3. The tube 1t and the opening 3h1 form a part of the aerosol channel. The storage compartment 30 is isolated from the opening 3h1 by the tube 1t. The storage compartment 30 is in communication with the openings 3h2 and 3h3 of the upper cap 3. The e-liquid stored in the storage compartment 30 may reach the recess 5c of the aerosol generation component 5 through the openings 3h2 and 3h3.

As shown in FIG. 3K, a vaporization chamber 7c is defined between the aerosol generation component 5 and the middle cap 71. Aerosol is generated by heating the e-liquid on the aerosol generation component 5 in the vaporization chamber 7c in advance, and then the aerosol enters the tube 1t through the notch 3pg and the cavity 3c of the upper cap 3 (referring to FIG. 3D) .

As shown in FIG. 3J, the electrically conductive pin 5p1 of the aerosol generation component 5 is in direct contact with the electrically conductive structure 9p1. The electrically conductive pin 5p2 of the aerosol generation component 5 is in direct contact with the electrically conductive structure 9p2. The electrically conductive pin 5p2 is in direct contact with the electrically conductive structure 9p2 through the section 5b1. The electrically conductive pin 5p1 is in direct contact with the electrically conductive structure 9p1 in the same manner.

The support 61 is disposed between the middle cap 71 and the lower cap 9. The support 61 is fixed between the middle cap 71 and the lower cap 9. The support 61 may be in direct contact with the middle cap 71 and the lower cap 9. The support 61 is disposed in the opening 71h1 of the middle cap 71. Through the structural designs of the middle cap 71 and the lower cap 9, the support 61 can be fixed between the middle cap 71 and the lower cap 9 without an additional member. The structural designs of the middle cap 71, the support 61, and the lower cap 9 reduce assembly difficulty of the cartridge 100A. The structural designs of the middle cap 71, the support 61, and the lower cap 9 reduce a quantity of the members inside the cartridge 100A.

The support 61 is disposed between the electrically conductive pins 5p1 and 5p2 of the aerosol generation component 5. The support 61 is disposed above the openings 9h1 and 9h2 of the lower cap 9. The opening 9h1 extends along an axis 9x1. The opening 9h2 extends along an axis 9x2. The extension direction of the opening 9h1 runs through the support 61. The extension direction of the opening 9h2 passes through the support 61.

If the aerosol generated by the aerosol generation component 5 is not completely inhaled by the user, the aerosol may be condensed into liquid in the vaporization chamber 7c. In a case that no support 61 is disposed, the liquid in the vaporization chamber 7c may leak out of the cartridge 100A through the opening 9h1 or 9h2 of the lower cap 9. The leaked liquid may cause damage to electronic members in the body 100B. The leaked liquid may also contaminate other valuables of the user in a process in which the user carries the vaporization device 100, thereby causing bad user experience.

The support 61 can effectively reduce a probability that the condensed liquid in the vaporization chamber 7c leaks from the opening 9h1 or 9h2 of the lower cap 9. The support 61 can effectively prevent the condensed liquid in the vaporization chamber 7c from leaking from the opening 9h1 or 9h2 of the lower cap 9. The support 61 can reduce condensed liquid leakage that causes a failure to the vaporization device 100. The support 61 can prolong the service life of the vaporization device 100.

As shown in FIG. 3J, the lower cap 9 includes a recess 9r2. During long-time use of the vaporization device, if a small amount of liquid still passes through the opening 61h on the support 61, the recess 9r2 can accommodate the liquid, thereby reducing a probability that the liquid leaks out of the cartridge 100A. Although not drawn in the figure, a liquid adsorption member may be disposed inside the recess 9r2. During long-time use of the vaporization device, if a small amount of liquid still passes through the opening 61h on the support 61, the liquid adsorption member disposed inside the recess 9r2 can adsorb the liquid, thereby reducing a probability that the liquid leaks out of the cartridge 100A.

The opening 2h1, the opening 2h2, and the opening 2h3 respectively expose the opening 3h1, the opening 3h2, and the opening 3h3.

As shown in FIG. 4B, the sealing member 4 is provided with an opening 4h, and the aerosol generation component 5 is provided with a recess 5c. When the sealing member 4 and the aerosol generation component 5 are combined with each other, the opening 4h may expose at least a part of the recess 5c.

The first protection plug 1a is detachably disposed, and extends into the opening 1h. The second protection plug 9b is detachably disposed, and extends into the openings 9h1 and 9h2 of the lower cap 9. In this way, the first protection plug 1a and the second protection plug 9b can prevent a foreign matter from entering the opening 1h, and the openings 9h1 and 9h2.

FIG. 4D is a schematic cross-sectional view of a cartridge according to some embodiments of this application. FIG. 4E is a schematic cross-sectional view of a cartridge according to some embodiments of this application.

As shown in FIG. 4D, the vaporization chamber 7c is defined between the aerosol generation component 5 and the middle cap 72. Aerosol generated after the aerosol generation component 5 heats the e-liquid is first generated in the vaporization chamber 7c, and then the aerosol enters the tube 1t through the notch 3pg and the cavity 3c of the upper cap 3 (referring to FIG. 3D) .

The tubular component 62 is disposed between the middle cap 72 and the lower cap 9. The tubular component 62 may be in direct contact with the middle cap 72 and the lower cap 9. The tubular component 62 is disposed in the opening 72h1 of the middle cap 72.

An opening 62h of the tubular component 62 extends along an axis 6x1. The opening 9h1 of the lower cap 9 extends along the axis 9x1. The opening 9h2 extends along an axis 9x2. The axis 6x1 does not overlap with the axis 9x1. The axis 6x1 does not overlap with the axis 9x2. The extension direction of the opening 62h does not overlap with the extension direction of the opening 9h1. The extension direction of the opening 62h does not intersect with the extension direction of the opening 9h1. The extension direction of the opening 62h does not overlap with the extension direction of the opening 9h2. The extension direction of the opening 62h does not intersect with the extension direction of the opening 9h2.

As shown in FIG. 4D, the lower cap 9 may include a recess 9r2. The recess 9r2 is in communication with the tubular component 62. The recess 9r2 is in communication with the opening 62h of the tubular component 62. The recess 9r2 and the opening 9h1 of the lower cap 9 are isolated from each other by the tubular component 62. The recess 9r2 and the opening 9h2 of the lower cap 9 are isolated from each other by the tubular component 62.

If the aerosol generated by the aerosol generation component 5 is not completely inhaled by the user, the aerosol may be condensed into liquid in the vaporization chamber 7c. The condensed liquid in the vaporization chamber 7c may reach the recess 9r2 through the tubular component 62, to be stored in the recess 9r2.

The layout of the tubular component 62 and the recess 9r2 avoids a possibility that the condensed liquid in the vaporization chamber 7c leaks from the opening 9h1 or 9h2 of the lower cap 9. The layout of the tubular component 62 and the recess 9r2 can reduce the probability that the liquid leaks out of the cartridge 100A. Although not drawn in the figure, a liquid adsorption member may be disposed in the recess 9r2, to further reduce the probability that the liquid leaks out of the cartridge 100A.

As shown in FIG. 4G, the tubular component 62 may include a first portion 62a and a second portion 62b. The first portion 62a has a wider outer diameter than that of the second portion 62b. The second portion 62b may run through the opening 72h1 of the middle cap 72. The outer diameter of the first portion 62a is greater than the inner diameter of the opening 72h1. The tubular component 62 may be fixed on the middle cap 72 by the first portion 62a, and will not fall out of the middle cap 72 due to vibration in use.

In some embodiments, the outer diameter of the second portion 62b is slightly greater than the inner diameter of the opening 72h1. When running through the opening 72h1, the second portion 62b of the tubular component 62 is in interference fit with the inner diameter of the opening 72h1. Therefore, the tubular component 62 and the middle cap 72 can be fixed with each other without a binder therebetween.

FIG. 5A is a schematic assembly view of a front surface of an upper cap and a lower cap according to some embodiments of this application. FIG. 5B is a schematic assembly view of a right side surface of an upper cap and a lower cap according to some embodiments of this application.

As shown in FIG. 5A, the right side of the upper cap 3 relative to the opening 3h1 is provided with a plurality of grooves, and the left side of the upper cap 3 relative to the opening 3h1 is provided with a plurality of grooves. The plurality of grooves at the right side on the upper cap 3 are in communication with each other to form a channel. The plurality of grooves at the left side on the upper cap 3 are in communication with each other to form a channel. The vaporization chamber 7c may be in fluid communication with the grooves 3hr1, 3hr2, 3hr3, and 3hr4. The vaporization chamber 7c may be in fluid communication with the grooves 3vr1, 3vr2, 3vr3, and 3vr4.

Fluid in the storage compartment 30 may enter the vaporization chamber 7c along a path 3f1 through the plurality of grooves on the upper cap 3. The fluid in the vaporization chamber 7c may enter the storage compartment 30 along the path 3f1 through the plurality of grooves on the upper cap 3. The fluid herein may be liquid or gas.

After the cartridge 100A is assembled, the pressure in the storage compartment 30 may vary due to the temperature or the external environment. If the pressure in the storage compartment 30 is excessively high, an excessively large amount of e-liquid may be caused to reach the aerosol generation component 5 through the openings 3h2 and 3h3 of the upper cap 3. When a volume of the e-liquid reaching the aerosol generation component 5 exceeds an upper limit of e-liquid that the aerosol generation component 5 can adsorb, the e-liquid in the storage compartment 30 is easy to drop into the vaporization chamber 7c through the aerosol generation component 5. An excessively large amount of liquid in the vaporization chamber 7c will increase the probability of e-liquid leakage of the cartridge 100A.

In addition, during continuous use of the vaporization device 100, the e-liquid in the storage compartment 30 is reduced continuously, so that a negative pressure may be produced in the storage compartment 30. The negative pressure in the storage compartment 30 may cause the e-liquid to be not easy to reach the aerosol generation component 5 from the openings 3h2 and 3h3 of the upper cap 3. In a case that the e-liquid adsorbed by the aerosol generation component 5 is insufficient, the aerosol generation component 5 at a high temperature may generate a burnt smell, causing bad user experience and shortening the service life of the aerosol generation component 5.

The foregoing problem can be resolved by providing a plurality of grooves on the upper cap 3. When the pressure in the storage compartment 30 is excessively high, the gas in the storage compartment 30 may reach the vaporization chamber 7c through the plurality of grooves provided on the upper cap 3, thereby decreasing the pressure in the storage compartment 30. When the pressure in the storage compartment 30 is excessively low, the gas in the vaporization chamber 7c may reach the storage compartment 30 through the plurality of grooves provided on the upper cap 3, thereby increasing the pressure in the storage compartment 30.

The plurality of grooves provided on the upper cap 3 also have many other advantages. For example, because of the path formed by the grooves is winding, the e-liquid entering the grooves from the storage compartment 30 may be accommodated in the grooves, and do not directly enter the vaporization chamber 7c. The plurality of grooves provided on the upper cap 3 can reduce the volume of the e-liquid entering the vaporization chamber 7c, and decrease the probability that the e-liquid leaks out of the cartridge 100A.

The right side of the lower cap 9 relative to the vaporization chamber 7c includes a plurality of grooves. The left side of the lower cap 9 relative to the vaporization chamber 7c includes a plurality of grooves. The plurality of grooves provided on the upright walls 9w1 and 9w2 of the lower cap 9 may become fluid channels. The plurality of grooves provided on the upright wall 9w1 are in communication with each other. The plurality of grooves provided on the upright wall 9w2 are in communication with each other.

As shown in FIG. 5A, fluid may reach the groove 3vr4 on the upper cap 3 through the grooves on the upright wall 9w2 along a path 9f1 from the vaporization chamber 7c. The fluid may reach the vaporization chamber 7c through the grooves on the upright wall 9w2 along the path 9f1 from the groove 3vr4 on the upper cap 3.

As shown in FIG. 5B, the fluid in the storage compartment 30 may enter the vaporization chamber 7c through the plurality of grooves on the upper cap 3 along a path 3f2. The fluid in the vaporization chamber 7c may enter the storage compartment 30 through the plurality of grooves on the upper cap 3 along the path 3f2. The fluid may reach the groove 3vr4 on the upper cap 3 through the grooves on the upright wall 9w2 along a path 9f2 from the vaporization chamber 7c. The fluid may reach the vaporization chamber 7c through the grooves on the upright wall 9w2 along the path 9f2 from the groove 3vr4 on the upper cap 3.

The plurality of grooves provided on the upright walls 9w1 and 9w2 of the lower cap 9 also have many other advantages. For example, because of the path formed by the grooves is winding, the e-liquid entering the grooves from the storage compartment 30 may be accommodated in the grooves, and do not directly enter the vaporization chamber 7c. The plurality of grooves provided on the upright walls 9w1 and 9w2 of the lower cap 9 can reduce the volume of the e-liquid entering the vaporization chamber 7c, and decrease the probability that the e-liquid leaks out of the cartridge 100A.

Referring to FIG. 5A and FIG. 4D, after the cartridge 100A is assembled, the upper cap sealing member 2 covers the upper cap 3. The gas in the vaporization chamber 7c may reach a junction between the opening 3h3 of the upper cap 3 and the opening 2h3 of the upper cap sealing member 2 along the path 3f2. The gas reaching the opening 2h3 of the upper cap sealing member 2 along the path 3f2 may cause a part of the upper cap sealing member 2 to deform. The gas reaching the opening 2h3 of the upper cap sealing member 2 along the path 3f2 may cause the upper cap sealing member 2 and the upper cap 3 to generate a gap, letting the gas enter the storage compartment 30 through the opening 2h3.

FIG. 5C is a schematic assembly view of a back surface of an upper cap and a lower cap according to some embodiments of this application. FIG. 5D is a schematic assembly view of a left side surface of an upper cap and a lower cap according to some embodiments of this application.

The back surface of the upper cap 3 is provided with grooves 3vr6 and 3vr7 extending in a vertical direction. The groove 3vr6 connects the groove 3hr2 and the groove 3hr3. The groove 3vr7 is in communication with the groove 3hr4. By comparing FIG. 5A with FIG. 5C, it can be learned that the front surface and the back surface of the upper cap 3 may be provided with different quantities of vertical grooves. In some embodiments, there is a relatively large quantity of vertical grooves provided on the front surface of the upper cap 3.

In some embodiments, the body 100B may supply power to the cartridge 100A. The body 100B may include an electrically conductive assembly 11, magnetic members 12, a sensor 13, a sealing kit 13a, a light guide holder 14, a main circuit board 15, a vibrator 17, magnetically

conductive members

18a and 18b, a charging conductive member 19, a power supply assembly 20, a power supply assembly support 21, a body housing 22, a charging circuit board 23, an adjustment circuit 24 and a port 25.

The body housing 22 has an opening 22h and a cavity 22c. The power supply assembly support 21 is disposed in the cavity 22c of the body housing 22 through the opening 22h of the body housing 22. The surface of the body housing 22 has light transmitting members 221. A plurality of light transmitting members 221 may surround and form a particular shape or image, for example, a circle. The light transmitting member 221 may be a through hole. The material of the body housing 22 may be metal, to improve the entire strength of the vaporization device 100. For example, the material of the body housing 22 may be aluminum, to reduce the entire weight.

The power supply assembly support 21 has a first end 211 and a second end 212 opposite to each other. In the first end 211 (or may be referred to as the top) , the power supply assembly support 21 has electrically-conducting grooves 21c1 and 21c2, and a recess portion 21g. The recess portion 21g is formed between the electrically-conducting grooves 21c1 and 21c2, and faces the openings 9h1 and 9h2 of the lower cap 9. The electrically-conducting grooves 21c1 and 21c2 correspond to the electrically conductive structures 9p1 and 9p2 disposed on the lower cap 9.

As shown in FIG. 7, the vaporization device 100 may be accommodated in an accommodation device 200. For example, the accommodation device 200 may include an accommodation groove 210, and the accommodation groove 210 may be configured to accommodate the vaporization device 100. On the other hand, in some embodiments, the accommodation device 200 may have a charging function, to charge the vaporization device 100. In some embodiments, the accommodation device 200 may include a magnetically-attracting member 220. The magnetically-attracting member 220 is disposed under one end of the accommodation groove 210.

In some embodiments, a central axis normal L3 extended from a top surface 222 of the magnetically-attracting member 220 does not run through the magnetically

conductive members

18a and 18b of the vaporization device 100, while a tangent L4 of a side edge 224 adjacent to the vaporization device 100 near the top surface 222 of the magnetically-attracting member 220 runs through the magnetically

conductive members

18a and 18b corresponding to the body 100B of the vaporization device 100. That is, the magnetically

conductive members

18a and 18b are closer to a central area of the accommodation device 200 than the magnetically-attracting member 220 is. For example, when the top surface 222 of the magnetically-attracting member 220 is the N-pole, an end surface 18c, which is outward the vaporization device 100 (a direction away from the cartridge 100A) , of the magnetically conductive member 18a is the S-pole, and an end surface 18d, which is outward the vaporization device 100 (a direction away from the cartridge 100A) of the magnetically conductive member 18b is the N-pole. Because the top surface 222 of the magnetically-attracting member 220 and the relatively close magnetically conductive member 18a of the magnetically

conductive members

18a and 18b attract each other, the vaporization device 100 may be correctly disposed in a specified position of the accommodation device 200. Because the top surface 222 of the magnetically-attracting member 220 and the relatively far magnetically conductive member 18b of the magnetically

conductive members

18a and 18b repel each other, it can be prevented that the magnetically conductive member 18a causes, because of too strong magnetic forces, an opposite side surface (that is, the end edge of the mouthpiece 1b of the cartridge 100A) of the vaporization device 100 to be warped or bounced. Therefore, the magnetically conductive member 18b has an effect of stably disposing the vaporization device 100 in the accommodation device 200.

In some embodiments, if a charging box or a charging base corresponding to the vaporization device 100 does not have a corresponding polarity (electric polarity) , the adjustment circuit 24 (referring to FIG. 6) on the charging circuit board 23 may be configured to adjust a current from the charging conductive member 19, to complete charging. Therefore, regardless of whether the vaporization device 100 is inserted in the charging box or the charging base in a forward direction or a backward direction, the adjustment circuit 24 may be configured to adjust a charging current, to complete charging of the vaporization device 100. For example, it is assumed that power is supplied to a first power input point P1 (not shown in the figure) and a second power input point P2 (not shown in the figure) of the charging circuit board 23 through the charging conductive member 19, a first circuit output point T1 of the charging circuit board 23 is a positive pole (+) output, and a second circuit output point T2 is a negative pole (-) output. In a first condition, when the power input point P1 receives a power input of positive pole power, and the second power input point P2 receives a power input of negative pole power, by adjusting a configuration of a switch circuit module of the adjustment circuit 24, the first circuit output point T1 (not shown in the figure) can be made to be a positive pole, and the second circuit output point T2 (not shown in the figure) can be made to be a negative pole. In a second condition, when the power input point P1 receives a power input of negative pole power, and the second power input point P2 receives a power input of positive pole power, by adjusting the configuration of a switch circuit module of the adjustment circuit 24, the first circuit output point T1 can be adjusted to be a positive pole, and the second circuit output point T2 can be adjusted to be a negative pole. Therefore, regardless of how the polarities of the first power input point P1 and the second power input point P2 change, the first circuit output point T1 and the second circuit output point T2 always maintain fixed output polarities by adjusting the adjustment circuit 24, and supply power to a next-level circuit, for example, the power supply assembly 20 and/or the main circuit board 15.

FIG. 8A is a schematic three-dimensional view of an upper cap according to some embodiments of this application. FIG. 8A shows an upper cap 31. The upper cap 31 and the upper cap 3 shown in FIG. 3A to FIG. 3E may be members compatible with each other. The upper cap 31 or the upper cap 3 may be selected as a member of the cartridge 100A without affecting the functional integrity of the cartridge 100A.

The upper cap 31 includes a surface 31s1 and a surface 31s2 opposite to the surface 31s1. In some embodiments, the surface 31s1 and the surface 31s2 may be parallel to each other. The upper cap 31 includes an opening 31h1. The opening 31h1 may be used as an aerosol channel. Aerosol generated by the aerosol generation component 5 may enter the tube 1t of the cartridge housing 1 through the opening 31h1, and then be inhaled by the user through the opening 1h of the cartridge housing 1.

The upper cap 31 includes a groove 31r1 communicating the surface 31s1 with the surface 31s2. The groove 31r1 may be perpendicular to the surface 31s1. The groove 31r1 may be perpendicular to the surface 31s2. The groove 31r1 may include a portion 31a, a portion 31b, and a portion 31c. The portion 31a, the portion 31b, and the portion 31c may be in communication with each other. The portion 31a, the portion 31b, and the portion 31c may extend in the same direction.

The surface 31s1 and the surface 31s2 of the upper cap 31 may be in communication with each other through a vertical groove (that is, the groove 31r1) .

The upper cap 31 includes a groove 31r2 located on one side of the opening 31h1. The groove 31r2 may include a portion 31d, a portion 31e, and a portion 31f. The portion 31d, the portion 31e, and the portion 31f may be in communication with each other. The portion 31d may extend parallelly to the portion 31f. The portion 31e may include an arched shape. The portion 31e may include a circular shape. The portion 31e may include an elliptic shape. The portion 31e may alternatively be referred to as a patterned portion in this disclosure.

The groove 31r2 may be connected to the surface 31s1 through the portion 31a of the groove 31r1. The groove 31r2 may be connected to the surface 31s2 through the portion 31c of the groove 31r1. The surface 31s1 and the surface 31s2 of the upper cap 31 may be in communication with each other through a non-vertical notch (formed by the groove 31r2, the portion 31a of the groove 31r1, and the portion 31c of the groove 31r1) .

The groove 31r1 provided on the upper cap 31 can balance the pressure between the storage compartment 30 and the outside environment. During continuous use of the vaporization device 100, the e-liquid in the storage compartment 30 is reduced continuously, so that a negative pressure may be produced in the storage compartment 30. The foregoing problem can be resolved by providing the groove 31r1 on the upper cap 31. When the pressure in the storage compartment 30 is excessively high, the gas in the storage compartment 30 may reach the vaporization chamber 7c through the groove 31r1 provided on the upper cap 31, thereby decreasing the pressure in the storage compartment 30. When the pressure in the storage compartment 30 is excessively low, the gas in the vaporization chamber 7c may reach the storage compartment 30 through the groove 31r1 provided on the upper cap 31, thereby increasing the pressure in the storage compartment 30.

The groove 31r2 provided on the upper cap 31 also has many advantages. For example, because paths between the portions of the groove 31r2 are winding, the e-liquid entering the groove 31r2 from the storage compartment 30 may be accommodated in the groove 31r2, and does not directly enter the vaporization chamber 7c. The groove 31r2 provided on the upper cap 31 may reduce a volume of the e-liquid entering the vaporization chamber 7c, and decrease a probability that the e-liquid leaks out of the cartridge 100A. In addition, the groove 31r2 may also be configured to store condensed liquid generated during use of the cartridge 100A, to decrease a probability that the condensed liquid leaks out of the cartridge 100A.

The notch 98r provided on the upright wall 98w1 of the lower cap 98 may reduce a volume of the e-liquid entering the vaporization chamber 7c, and decrease a probability that the e-liquid leaks out of the cartridge 100A. In addition, the notch 98r may also be configured to store condensed liquid generated during use of the cartridge 100A, to decrease a probability that the condensed liquid leaks out of the cartridge 100A.

As used herein, the terms "approximately" , "basically" , "substantially" , and "about" are used to describe and consider small variations. When used in combination with an event or a situation, the terms may refer to an example in which an event or a situation occurs accurately and an example in which the event or situation occurs approximately. As used herein with respect to a given value or range, the term "about" generally means in the range of ±10%, ±5%, ±1%, or ±0.5%of the given value or range. The range may be indicated herein as from one endpoint to another endpoint or between two endpoints. Unless otherwise specified, all ranges disclosed herein include endpoints. The term "substantially coplanar" may refer to two surfaces within a few micrometers (μm) positioned along the same plane, for example, within 10 μm, within 5 μm, within 1 μm, or within 0.5 μm positioned along the same plane. When reference is made to "substantially" the same numerical value or characteristic, the term may refer to a value within ±10%, ±5%, ±1%, or ±0.5%of the average of the values.

As used herein, the terms "approximately" , "basically" , "substantially" , and "about" are used to describe and explain small variations. When used in combination with an event or a situation, the terms may refer to an example in which an event or a situation occurs accurately and an example in which the event or situation occurs approximately. For example, when being used in combination with a value, the term may refer to a variation range of less than or equal to ±10%of the value, for example, less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. For example, if a difference between two values is less than or equal to ±10%of an average value of the value (for example, less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%) , it could be considered that the two values are "substantially" or "approximately" the same. For example, being "substantially" parallel may refer to an angular variation range of less than or equal to ±10° with respect to 0°, for example, less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°. For example, being "substantially" perpendicular may refer to an angular variation range of less than or equal to ±10° with respect to 90°, for example, less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°.

For example, two surfaces can be deemed to be coplanar or substantially coplanar if a displacement between the two surfaces is no greater than 5 μm, no greater than 2 μm, no greater than 1 μm, or no greater than 0.5 μm. A surface can be deemed to be planar or substantially planar if a displacement between any two points on the surface with respect to a plane is no greater than 5 μm, no greater than 2 μm, no greater than 1 μm, or no greater than 0.5 μm.

As used herein, the terms "conductive" , "electrically conductive" and "electrical conductivity" refer to an ability to transport an electric current. Electrically conductive materials typically indicate those materials that exhibit little or no opposition to the flow of an electric current. One measure of electrical conductivity is Siemens per meter (S/m) . Typically, an electrically conductive material is a material having an electrical conductivity greater than approximately 10 ⁴ S/m (such as at least 10 ⁵ S/m or at least 10 ⁶ S/m) . The electrical conductivity of a material can sometimes vary with temperature. Unless otherwise specified, the electrical conductivity of a material is measured at room temperature.

As used herein, singular terms "a" , "an" , and "the" may include plural referents unless the context clearly dictates otherwise. In the description of some embodiments, assemblies provided "on" or "above" another assembly may encompass a case in which a previous assembly is directly on a latter assembly (for example, in physical contact with the latter assembly) , and a case in which one or more intermediate assemblies are located between the previous assembly and the latter assembly.

As used herein, for ease of description, space-related terms such as "under" , "below" , "lower portion" , "above" , "upper portion" , "lower portion" , "left side" , "right side" , and the like may be used herein to describe a relationship between one member or feature and another member or feature as shown in the figures. In addition to orientation shown in the figures, space-related terms are intended to encompass different orientations of the device in use or operation. A device may be oriented in other ways (rotated 90 degrees or at other orientations) , and the space-related descriptors used herein may also be used for explanation accordingly. It should be understood that when a member is "connected" or "coupled" to another member, the member may be directly connected to or coupled to another member, or an intermediate member may exist.

Several embodiments of this disclosure and features of details are briefly described above. The embodiments described in this disclosure may be easily used as a basis for designing or modifying other processes and structures for realizing the same or similar objectives and/or obtaining the same or similar advantages introduced in the embodiments in the specification.
