Cigarette bullet and electron cigarette device

Cross Reference to Related Applications

This application is based on the application number: 202010019529.3 and 202020038013.9, filed on and claiming priority from the chinese patent application having a filing date of 2020, 01/08, which is hereby incorporated by reference in its entirety

Technical Field

The present application relates generally to electronic devices, and more particularly to a vaporization device for providing an inhalable aerosol (aerosol).

Background

With the stricter and stricter regulations and restrictions of tobacco products in various regions and governments around the world, the demand of people for tobacco substitutes is continuously growing. The e-vapor device may be a tobacco substitute that atomizes a nebulizable material (e.g., tobacco tar) by an e-aerosol generating device or an e-atomizing device to generate an aerosol for inhalation by a user to achieve a sensory experience that simulates smoking. Compared with the traditional tobacco products, the electronic cigarette device can effectively reduce harmful substances generated by combustion as a substitute thereof, and further reduce harmful side effects of smoking.

Existing electronic cigarette products do not take into account the pressure balance of the oil reservoir. In existing electronic cigarette products, the oil reservoir is typically designed to be completely sealed to prevent the escape of the vaporizable solution. In the transportation process of the manufactured electronic cigarette product, the pressure in the oil storage chamber may rise due to temperature change or air pressure change. The pressure rise in the oil reservoir will cause a large amount of smoke to flow towards the heating assembly and may cause problems with leakage of smoke from the electronic cigarette product. In addition, as the user continues to use the electronic cigarette product, the vaporizable solution in the oil storage chamber is continuously consumed and reduced, so that the pressure in the oil storage chamber is reduced to form negative pressure. The negative pressure makes the gasifiable solution in the oil storage chamber difficult to uniformly flow onto the heating assembly, so that the heating assembly does not uniformly adsorb the gasifiable solution. At this time, when the temperature of the heating element rises, there is a high probability that the heating element will burn empty to generate scorched smell, which results in poor user experience.

Accordingly, the present disclosure provides an atomizing device that can solve the above-mentioned problems.

Section 5b2 is connected between section 5b1 and section 5b 3. The direction of extension of section 5b2 is substantially perpendicular to the direction of extension of sections 5b1 and 5b 3.

The shape of the conductive pins 5p1 and 5p2 has many advantages. During the assembly of the cartridge 100A, the conductive pins 5p1 and 5p2 are designed such that the conductive pins 5p1 and 5p2 and the conductive structures 9p1 and 9p2 can easily contact each other. The shape design of the conductive leads 5p1 and 5p2 reduces the chance of poor contact between the conductive leads 5p1 and 5p2 and the conductive structures 9p1 and 9p 2. The configuration of the conductive pins 5p1 and 5p2 further reduces the number of assembly steps of the cartridge 100A.

Although not depicted in fig. 3F, the heating element 5 may include a heating circuit disposed on the bottom surface 5s 1. The heating circuit disposed on the bottom surface 5s1 is electrically connected to the conductive pins 5p1 and 5p 2. The atomizing device 100 may raise the temperature of the heating element 5 by providing power to the heating circuit on the bottom surface 5s 1.

A portion of the pipe 1t extends into the opening 3h1 of the heating assembly upper cover 3. Tube 1t and opening 3h1 form part of the aerosol passage. The storage compartment 30 is isolated from the opening 3h1 via the tube 1 t. The storage compartment 30 communicates with the openings 3h2 and 3h3 of the heating unit upper cover 3. The tobacco tar stored in the storage compartment 30 can reach the groove 5c of the heating element 5 through the openings 3h2 and 3h 3.

As shown in fig. 3K, the heating element 5 and the heating element lower cover 71 define an atomization chamber 7c therebetween. The aerosol generated by the heating element 5 after heating the tobacco tar is first generated in the atomizing chamber 7c and then enters the tube 1t through the groove 3pg and the cavity 3c (see fig. 3D) of the heating element upper cover 3.

As shown in fig. 3J, the conductive pin 5p1 of the heating element 5 is in direct contact with the conductive structure 9p 1. The conductive pin 5p2 of the heating element 5 is in direct contact with the conductive structure 9p 2. The conductive pin 5p2 directly contacts the conductive structure 9p2 via the segment 5b 1.

The bracket 61 is disposed between the heating assembly lower cover 71 and the cartridge base 9. The bracket 61 is fixed between the heating assembly lower cover 71 and the cartridge base 9. The bracket 61 may be in direct contact with the heating assembly lower cover 71 and the cartridge base 9. The bracket 61 is disposed in the opening 71h1 of the heating unit lower cover 71. By virtue of the structural design of the heating element lower cover 71 and the cartridge base 9, the bracket 61 can be fixed between the heating element lower cover 71 and the cartridge base 9 without additional components. The structural design of the heating assembly lower cover 71, the bracket 61 and the cartridge base 9 reduces the difficulty of assembly of the cartridge 100A. The structural design of the heating assembly lower cover 71, the bracket 61, and the cartridge base 9 reduces the number of components in the cartridge 100A.

The bracket 61 is disposed between the conductive pins 5p1 and 5p2 of the heating element 5. The bracket 61 is disposed above the openings 9h1 and 9h2 of the cartridge base 9.

The opening 9h2 extends in the direction passing through the bracket 61.

If the aerosol generated by the heating element 5 is not completely inhaled by the user, it may condense to a liquid in the nebulizing chamber 7 c. Without the provision of the bracket 61, liquid within the nebulizing chamber 7c may leak outside the cartridge 100A via the opening 9h1 or 9h2 of the cartridge base 9. The leaked liquid may cause damage to electronic components within the main body 100B. The leaked liquid may also contaminate other valuables of the user during the process of carrying the aerosolization device 100, resulting in a poor user experience.

The bracket 61 effectively reduces the probability of condensed liquid in the atomizing chamber 7c leaking from the opening 9h1 or 9h2 of the cartridge base 9. The bracket 61 can effectively prevent the condensed liquid in the atomization chamber 7c from leaking from the opening 9h1 or 9h2 of the cartridge base 9. The bracket 61 reduces leakage of condensed liquid that could cause malfunction of the atomizing apparatus 100. The bracket 61 may increase the service life of the atomizing device 100.

As shown in fig. 3J, the cartridge base 9 may include a recess 9r 2. In the long-term use of the atomizer, if a small amount of liquid still passes through the opening 61h of the holder 61, the groove 9r2 can contain the liquid, thereby reducing the possibility of the liquid leaking to the outside of the cartridge 100A. Although not shown, a wicking assembly can be disposed within recess 9r 2. If a small amount of liquid still passes through the opening 61h of the holder 61 during the long-term use of the atomizing device, the liquid absorbing component arranged in the groove 9r2 can absorb the liquid, thereby reducing the probability of the liquid leaking to the outside of the cartridge 100A.

Figure 4D illustrates a cartridge cross-sectional schematic view according to some embodiments of the present application. Figure 4E illustrates a schematic cartridge cross-section in accordance with some embodiments of the present application.

As shown in fig. 4D, the heating element 5 and the heating element lower cover 72 define an atomization chamber 7c therebetween. The aerosol generated by the heating element 5 heating the tobacco tar is first generated in the atomizing chamber 7c, and then enters the tube 1t through the groove 3pg and the cavity 3c (see fig. 3D) of the heating element upper cover 3.

The tubular assembly 62 is disposed between the heating assembly lower cover 72 and the cartridge base 9. The tubular assembly 62 may be in direct contact with the heating assembly lower cover 72 and the cartridge base 9. The tubular member 62 is disposed in the opening 72h1 of the heating member lower cover 72.

The opening 62h of the tubular assembly 62 extends in the direction of the axis 6x 1. The opening 9h1 of the cartridge base 9 extends in the direction of the axis 9x 1. The opening 9h2 extends in the direction of the axis 9x 2. The axis 6x1 does not overlap the axis 9x 1. The axis 6x1 does not overlap the axis 9x 2.

The extending direction of the opening 62h does not overlap with the extending direction of the opening 9h 2. The extending direction of the opening 62h does not intersect with the extending direction of the opening 9h 2.

As shown in fig. 4D, the cartridge base 9 may include a recess 9r 2. The groove 9r2 communicates with the tubular assembly 62. The groove 9r2 communicates with the opening 62h of the tubular member 62. The groove 9r2 and the opening 9h1 of the cartridge base 9 are isolated from each other by the tubular member 62. The groove 9r2 and the opening 9h2 of the cartridge base 9 are isolated from each other by the tubular member 62.

If the aerosol generated by the heating element 5 is not completely ingested by the user, it may condense into a liquid in the nebulizing chamber 7 c. The condensed liquid in the atomizing chamber 7c can reach the groove 9r2 through the tubular member 62 and be stored in the groove 9r 2.

The arrangement of the tubular member 62 and the recess 9r2 avoids the possibility of condensed liquid within the atomising chamber 7c leaking out of the opening 9h1 or 9h2 of the cartridge base 9. The arrangement of the tubular member 62 and the recess 9r2 reduces the chance of liquid leaking out of the cartridge 100A.

Figure 5A illustrates a front assembly schematic of a heating assembly cover and cartridge base according to some embodiments of the present application. Figure 5B illustrates a right side combination schematic of a heating assembly upper cover and cartridge base according to some embodiments of the present application.

As shown in fig. 5A, the heating element upper cover 3 has a plurality of grooves on the right side with respect to the opening 3h1 and a plurality of grooves on the left side with respect to the opening 3h 1. The grooves on the right side of the heating component upper cover 3 are communicated with each other to form a channel. The plurality of grooves on the left side of the heating element upper cover 3 are communicated with each other to form a channel. Atomization chamber 7c may be in fluid communication with slots 3hr1, 3hr2, 3hr3, and 3hr 4. The nebulization chamber 7c can be in fluid communication with the grooves 3vr1, 3vr2, 3vr3 and 3vr 4.

Fluid in reservoir 30 may travel along path 3f1 through a plurality of slots in heating element cover 3 into atomization chamber 7 c. Fluid in the atomization chamber 7c may travel along path 3f1 through a plurality of slots in the heating element lid 3 into the reservoir 30. The fluid referred to herein may be a liquid or a gas.

When the cartridge 100A is assembled, the pressure within the storage compartment 30 may change due to temperature or the external environment. If the pressure in the storage compartment 30 is too high, it may cause excessive amounts of soot to reach the heating element 5 through the openings 3h2 and 3h3 of the heating element cover 3. When the volume of the soot reaching the heating element 5 exceeds the upper limit that the heating element 5 can adsorb, the soot in the storage compartment 30 easily drops through the heating element 5 into the atomization chamber 7 c. Excessive liquid in the aerosolizing chamber 7c will increase the chance of soot leakage from the cartridge 100A.

In addition, during continued use of the atomization device 100, the amount of tobacco smoke in the storage compartment 30 continues to decrease, possibly creating a negative pressure in the storage compartment 30. The negative pressure in the storage compartment 30 may cause the tobacco tar to be difficult to reach the heating element 5 from the openings 3h2 and 3h3 of the heating element upper cover 3. In the case where the amount of the smoke oil adsorbed by the heating element 5 is insufficient, the heating element 5 of high temperature may generate scorched smell, produce bad user experience, and reduce the service life of the heating element 5.

The above problem can be solved by providing a plurality of grooves on the heating element upper cover 3. When the pressure in the storage chamber 30 is too high, the gas in the storage chamber 30 can reach the atomizing chamber 7c through the plurality of grooves formed on the heating element upper cover 3, thereby reducing the pressure in the storage chamber 30. When the pressure in the storage chamber 30 is too low, the gas in the atomization chamber 7c can reach the storage chamber 30 through a plurality of grooves formed on the heating element cover 3, thereby increasing the pressure in the storage chamber 30.

The provision of a plurality of slots in the heating element cover 3 also has a number of other advantages. For example, due to the tortuous path between the slots, tobacco tar entering the slots from the storage compartment 30 will be received in the grooves and will not enter the atomization chamber 7c directly. The plurality of grooves formed in the heating element cover 3 reduces the volume of the tobacco tar entering the atomization chamber 7c and reduces the probability of the tobacco tar leaking to the outside of the cartridge 100A.

The cartridge base 9 comprises a plurality of slots on the right side relative to the aerosolizing chamber 7 c. The cartridge base 9 comprises a plurality of slots on the left side relative to the aerosolizing chamber 7 c. The plurality of grooves provided in the upright walls 9w1 and 9w2 of the cartridge base 9 may be channels for fluid. The plurality of grooves provided on the upright wall 9w1 communicate with each other. The plurality of grooves provided on the upright wall 9w2 communicate with each other.

As shown in fig. 5A, fluid may follow the path 9f1 from the atomizer chamber 7c via the grooves in the upstanding wall 9w2 to the grooves 3vr4 on the heating assembly upper cover 3. Fluid may follow the path 9f1 from the recess 3vr4 in the heating assembly cover 3 to the atomization chamber 7c via the recess in the upstanding wall 9w 2.

As shown in fig. 5B, the fluid in the storage chamber 30 can enter the atomization chamber 7c along the path 3f2 through a plurality of slots on the heating element cover 3. Fluid in the atomization chamber 7c can enter the storage chamber 30 along the path 3f2 through a plurality of slots in the heating element cover 3. The fluid can follow the path 9f2 from the atomising chamber 7c via the grooves in the upstanding wall 9w2 to the grooves 3vr4 on the heating assembly upper cover 3. Fluid may follow the path 9f2 from the recess 3vr4 in the heating assembly cover 3 to the atomization chamber 7c via the recess in the upstanding wall 9w 2.

The provision of a plurality of slots in the upstanding walls 9w1 and 9w2 of the cartridge base 9 also provides a number of other advantages. For example, due to the tortuous path between the slots, tobacco tar entering the slots from the storage compartment 30 will be received in the grooves and will not enter the atomization chamber 7c directly. The plurality of slots provided in the upstanding walls 9w1 and 9w2 of the cartridge base 9 reduce the volume of tobacco tar that enters the atomizing chamber 7c and reduces the chance of the tobacco tar leaking outside of the cartridge 100A.

Referring to fig. 5A and 4D, the upper lid sealing element 2 overlies the heating element upper lid 3 after the cartridge 100A is assembled. The gas in the atomizing chamber 7c can reach the interface of the opening 3h3 of the heating element upper cover 3 and the opening 2h3 of the upper cover sealing element 2 along the path 3f 2. The gas arriving at opening 2h3 of the lid seal assembly 2 along path 3f2 may locally deform the lid seal assembly 2. The gas that reaches opening 2h3 of lid seal assembly 2 along path 3f2 may cause lid seal assembly 2 and heating assembly lid 3 to slit, allowing the gas to enter storage compartment 30 through opening 2h 3.

Figure 5C illustrates a rear assembly view of a heating assembly cover and cartridge base according to some embodiments of the present application. Figure 5D illustrates a left side combination schematic of a heating assembly upper cover and cartridge base according to some embodiments of the present application.

The rear surface of the heating element upper cover 3 has grooves 3vr6 and 3vr7 extending in the vertical direction. Slot 3vr6 connects slots 3hr2 and slots 3hr 3. Tank 3vr7 communicates with tank 3hr 4. As can be seen from a comparison of FIGS. 5A and 5C, the heating element top cover 3 may have a different number of vertical slots on the front and back sides thereof. In some embodiments, the number of vertical slots provided in the front surface of the heating element cover 3 is large.

In some embodiments, the body 100B may supply power to the cartridge 100A. The body 100B may include a conductive element 11, a magnetic element 12, a sensor 13, a seal assembly 13a, a light guide frame 14, a main circuit board 15, a vibrator 17, magnetic conductive elements 18a, 18B, a charging guide 19, a power supply element 20, a power supply element support 21, a body housing 22, a charging circuit board 23, an adjustment circuit 24, and a port 25.

The main body case 22 has an opening 22h and a cavity 22 c. The power module holder 21 is disposed in the cavity 22c of the main body case 22 through the opening 22h of the main body case 22. The surface of the main body case 22 has a light transmitting member 221. The plurality of light-transmitting elements 221 may be surrounded to form a specific shape or pattern, such as a circle. The light transmissive member 221 may be a through hole. The material of the main body housing 22 may be metal to enhance the strength of the entire atomizer 100. For example, the material of the main body case 22 may be aluminum to reduce the overall weight.

The power module holder 21 has a first end 211 and a second end 212 opposite to each other. At the first end 212 (or top), the power module holder 21 has conductive slots 21c1, 21c2 and a slot 21 g. The groove portion 21g is formed between the conductive grooves 21c1, 21c2 and faces the openings 9h1, 9h2 of the cartridge base 9. The conductive slots 21c1, 21c2 correspond to the conductive structures 9p1, 9p2 provided to the cartridge base 9.

As illustrated in fig. 7, the atomizing device 100 may be housed in a housing 200. For example, the accommodating device 200 may have an accommodating groove 210, and the accommodating groove 210 may be used to accommodate the atomizing device 100. On the other hand, in some embodiments, the accommodating device 200 may be used for a charging function to charge the atomizing device 100. In some embodiments, the accommodating device 200 may include a magnetic component 220, and the magnetic component 220 is disposed below one end of the accommodating groove 210.

In some embodiments, the central axis normal L3 extending from the top surface 222 of the magnetic attraction element 220 does not extend through the magnetic conductive members 18a and 18B of the atomization device 100, and a tangent L4 near the top surface 222 of the magnetic attraction element 220 and adjacent to the side edge 224 of the atomization device 100 extends through the magnetic conductive members 18a and 18B of the main body 100B of the atomization device 100. That is, the

magnetic guide members

18a, 18b are located adjacent to the middle region of the receiving device 200 than the magnetic attraction member 220. For example, when the top surface 222 of the magnetic element 220 is N-polar, the end surface 18c of the magnetic guide 18a facing the outside of the atomizing device 100 (opposite to the direction of the cartridge 100A) is S-polar, and the end surface 18d of the magnetic guide 18b facing the outside of the atomizing device 100 (opposite to the direction of the cartridge 100A) is N-polar. Since the top surface 222 of the magnetic attraction component 220 and the magnetic conductive member 18a closer to the magnetic

conductive members

18a and 18b attract each other, the atomization device 100 can be correctly disposed at the designated position of the accommodating device 200. Since the top surface 222 of the magnetic attraction component 220 and the magnetic guide 18b farther from the

magnetic guide

18a, 18b are mutually exclusive, the opposite side surface of the atomizing device 100 (i.e. the end edge of the mouthpiece cover 1 of the cartridge 100A) from the magnetic guide 18a is prevented from tilting or bouncing off due to the excessive magnetic attraction. The magnetic guide 18b has the effect of stably mounting the atomizing device 100 in the housing 200.

In some embodiments, if the charging cartridge or the charging seat corresponding to the atomization device 100 does not have opposite polarity (electric polarity), the adjusting circuit 24 (see fig. 6) on the charging circuit board 23 is configured to adjust the current from the charging guide 19 to complete charging. Therefore, the adjusting circuit 24 is configured to adjust the charging current to complete the charging of the atomization device 100 when the atomization device 100 is inserted into the charging box or the charging stand in the forward or reverse direction. For example, assume that the charging circuit board 23 is powered by the charging guide 19 at a first power input point P1 (not shown) and a second power input point P2 (not shown), the first circuit output T1 of the charging circuit board 23 is a positive (+) output, and the second circuit output point T2 is a negative (-) output. In the first case, when the power input point P1 receives the power input as positive power and the second power input point P2 receives the power input as negative power, the configuration of the switch circuit module of the adjusting circuit 24 is adjusted such that the first circuit output point T1 (not shown) is positive and the second circuit output point T2 (not shown) is negative. In the second case, when the power input received by the power input point P1 is negative, and the power input received by the second power input point P2 is positive, the configuration of the switch circuit module of the adjusting circuit 24 can make the first circuit output point T1 positive, and the second circuit output point T2 negative. Therefore, regardless of the polarity change of the first power input point P1 and the second power input point P2, the first circuit output point T1 and the second circuit output point T2 always maintain a fixed output polarity through the adjusting circuit 24, and supply power to the lower-stage circuit, such as the power module 20 and/or the main circuit board 15.
