Description

Atomizing device

Technical field

The present application generally relates to an electronic device, and in particular, to an atomization device (vaporization device) that provides inhalable aerosol (aerosol).

Background technique

As the control and restriction of tobacco products by governments in various regions of the world become more and more stringent, people's demand for alternatives to tobacco is also growing. The electronic cigarette device may be a tobacco substitute, which atomizes a vaporizable material (for example, e-liquid) through an electronic aerosol generating device or an electronic atomizing device to generate an aerosol for inhalation by the user, Then achieve the sensory experience of simulating smoking. Compared with traditional tobacco products, e-cigarette devices can effectively reduce harmful substances produced by combustion, thereby reducing the harmful side effects of smoking.

The existing electronic cigarette products do not consider the pressure balance of the oil storage chamber. In existing electronic cigarette products, the oil storage chamber is generally designed to be completely sealed to prevent the vaporizable solution from overflowing. The finished electronic cigarette product may increase the pressure in the oil storage chamber due to changes in temperature or air pressure during the transportation process. The increase in pressure in the oil storage chamber will cause a large amount of e-liquid to flow to the heating component, and may cause the problem of e-liquid leakage of electronic cigarette products. In addition, as users continue to use electronic cigarette products, the vaporizable solution in the oil storage chamber is continuously consumed and reduced, so that the pressure in the oil storage chamber decreases and a negative pressure is formed. The negative pressure makes it difficult for the gasifiable solution in the oil storage chamber to evenly flow to the heating component, so that the heating component does not uniformly adsorb the gasifiable solution. At this time, when the temperature of the heating element rises, there will be a high probability of empty burning and a burnt smell, resulting in a bad user experience.

Therefore, the present disclosure proposes an atomization device that can solve the above-mentioned problems.

Summary of the invention

An atomization device is proposed. The proposed atomization device includes a housing, a heating element upper cover, a heating element, a heating element lower cover and a cartridge base. The first straight wall of the cartridge base includes a first groove, a second groove, and a third groove. The first groove and the second groove extend along a first direction, and the third groove extends along a second direction. The third groove connects the first groove and the second groove.

An atomization device is proposed. The proposed atomization device includes a cartridge and a main body. The main body has an opening configured to receive a portion of the cartridge.

A storage compartment 30 is defined between the cartridge housing 1, the tube 1t, and the upper cover sealing assembly 2. The storage compartment 30 can store e-liquid. A part of the tube 1t extends into the opening 3h1 of the upper cover 3 of the heating assembly. The tube 1t and the opening 3h1 form a part of the aerosol channel. The storage compartment 30 is isolated from the opening 3h1 via a pipe 1t. The storage compartment 30 is in communication with the openings 3h2 and 3h3 of the upper cover 3 of the heating assembly. The e-liquid stored in the storage compartment 30 can reach the groove 5c of the heating assembly 5 through the openings 3h2 and 3h3.

As shown in FIG. 3K, an atomization chamber 7c is defined between the heating assembly 5 and the lower cover 71 of the heating assembly. The aerosol generated by the heating element 5 heating the e-liquid 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 upper cover 3 of the heating element.

As shown in FIG. 3J, the conductive pin 5p1 of the heating element 5 is in direct contact with the conductive structure 9p1. The conductive pin 5p2 of the heating element 5 directly contacts the conductive structure 9p2. The conductive pin 5p2 directly contacts the conductive structure 9p2 via the section 5b1. The conductive pin 5p1 directly contacts the conductive structure 9p1 in the same manner.

The bracket 61 is arranged between the lower cover 71 of the heating assembly and the cartridge base 9. The bracket 61 is fixed between the lower cover 71 of the heating assembly and the cartridge base 9. The bracket 61 can directly contact the lower cover 71 of the heating assembly and the cartridge base 9. The bracket 61 is disposed in the opening 71h1 of the lower cover 71 of the heating assembly. With the structural design of the lower heating element cover 71 and the cartridge base 9, the bracket 61 can be fixed between the lower heating element cover 71 and the cartridge base 9 without additional components. The structural design of the lower cover 71 of the heating assembly, the support 61 and the cartridge base 9 reduces the difficulty of assembling the cartridge 100A. The structural design of the lower cover 71 of the heating assembly, the support 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 9h1 extends along the direction of the axis 9x1. The opening 9h2 extends in the direction of the axis 9x2. The extending direction of the opening 9h1 passes through the bracket 61. The extending direction of the opening 9h2 passes through the bracket 61.

If the aerosol generated by the heating assembly 5 is not completely ingested by the user, it may condense into a liquid in the atomizing chamber 7c. Without the support 61, the liquid in the atomization chamber 7c may leak to the outside of the cartridge 100A through the opening 9h1 or 9h2 of the cartridge base 9. The leaked liquid may damage the electronic components in the main body 100B. The leaked liquid may also contaminate other valuables of the user while the user is carrying the atomization device 100, resulting in a bad user experience.

The bracket 61 can effectively reduce the probability of the condensed liquid in the atomization 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 can reduce the leakage of the condensed liquid and cause the atomization device 100 to malfunction. The bracket 61 can increase the service life of the atomization device 100.

As shown in FIG. 3J, the cartridge base 9 may include a groove 9r2. During the long-term use of the atomization device, if a small amount of liquid still passes through the opening 61h on the holder 61, the groove 9r2 can contain the liquid, reducing the probability of the liquid leaking to the outside of the cartridge 100A. Although it is not shown in the figure, a liquid suction component can be arranged in the groove 9r2. During the long-term use of the atomizing device, if a small amount of liquid still passes through the opening 61h on the holder 61, the liquid suction component arranged in the groove 9r2 can absorb the liquid, reducing the probability of liquid leaking to the outside of the cartridge 100A.

The bracket 61 is disposed in the opening 71h1 of the lower cover 71 of the heating assembly. The bracket 61 is arranged between the heating assembly 5 and the cartridge base 9. The bracket 61 is arranged between the heating assembly 5 and the opening 9h1 of the cartridge base 9.

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

As shown in FIG. 4B, the sealing component 4 has an opening 4h, and the heating component 5 has a groove 5c. When the sealing assembly 4 and the heating assembly 5 are combined with each other, the opening 4h may expose at least a part of the groove 5c.

The tubular component 62 may be made of a metal material. In certain embodiments, the tubular component 62 may comprise stainless steel.

The lower cover 72 of the heating assembly may include an opening 72h1. The tubular component 62 can be arranged on the lower cover 72 of the heating component. The tubular component 62 can be disposed on the opening 72h1 on the lower cover 72 of the heating component. A portion of the tubular component 62 may extend into the opening 72h1.

As demonstrated in FIGS. 4A to 4C, in some embodiments, the atomizing device 100 may include a first protective plug 1a and a second protective plug 9b. The first protective plug 1a is detachably installed and extends into the opening 1h. The second protective plug 9b is detachably installed and extends into the openings 9h1 and 9h2 of the cartridge base 9. In this way, the first protection plug 1a and the second protection plug 9b can prevent foreign matter from entering the opening 1h and the openings 9h1 and 9h2.

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

As shown in FIG. 4D, an atomization chamber 7c is defined between the heating assembly 5 and the lower cover 72 of the heating assembly. The aerosol generated by the heating element 5 heating the e-liquid 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 upper cover 3 of the heating element.

The tubular component 62 is arranged between the lower cover 72 of the heating component and the cartridge base 9. The tubular component 62 can directly contact the lower cover 72 of the heating component and the cartridge base 9. The tubular component 62 is disposed in the opening 72h1 of the lower cover 72 of the heating component.

The opening 62h of the tubular component 62 extends along the direction of the shaft 6x1. The opening 9h1 of the cartridge base 9 extends along the axis 9x1. The opening 9h2 extends in the direction of the axis 9x2. Axis 6x1 and axis 9x1 do not overlap. Axis 6x1 and axis 9x2 do not overlap. The extending direction of the opening 62h and the extending direction of the opening 9h1 do not overlap. The extending direction of the opening 62h does not intersect the extending direction of the opening 9h1. The extending direction of the opening 62h and the extending direction of the opening 9h2 do not overlap. The extending direction of the opening 62h does not intersect the extending direction of the opening 9h2.

As shown in FIG. 4D, the cartridge base 9 may include a groove 9r2. The groove 9r2 communicates with the tubular component 62. The groove 9r2 communicates with the opening 62h of the tubular component 62. The groove 9r2 and the opening 9h1 of the cartridge base 9 are separated from each other by the tubular component 62. The groove 9r2 and the opening 9h2 of the cartridge base 9 are separated from each other by the tubular component 62.

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

The configuration of the tubular component 62 and the groove 9r2 avoids the possibility of the condensed liquid in the atomizing chamber 7c leaking from the opening 9h1 or 9h2 of the cartridge base 9. The configuration of the tubular component 62 and the groove 9r2 can reduce the probability of liquid leaking to the outside of the cartridge 100A. Although not shown in the figure, a liquid suction component can be arranged in the groove 9r2 to further reduce the probability of liquid leakage to the outside 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 part 62a has a wider outer diameter than the second part 62b. The second portion 62b may pass through the opening 72h1 of the lower cover 72 of the heating assembly. The outer diameter of the first portion 62a is larger than the inner diameter of the opening 72h1. The tubular component 62 can be fixed to the lower heating component cover 72 via the first portion 62a, and will not fall off from the lower heating component cover 72 due to vibration during use.

In some embodiments, the outer diameter of the second portion 62b is slightly larger than the inner diameter of the opening 72h1. When the second portion 62b of the tubular component 62 passes through the opening 72h1, it is in interference fit with the inner diameter of the opening 72h1. Therefore, the tubular component 62 and the lower cover 72 of the heating component can be fixed to each other without an adhesive.

FIG. 5A illustrates a schematic view of the front combination of the upper cover of the heating assembly and the cartridge base according to some embodiments of the present application. FIG. 5B illustrates a schematic diagram of the right side combination of the upper cover of the heating assembly and the 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 has a plurality of grooves on the left side with respect to the opening 3h1. The plurality of grooves on the right side of the upper cover 3 of the heating assembly communicate with each other to form a channel. The plurality of grooves on the left side of the upper cover 3 of the heating assembly communicate with each other to form a channel. The atomization chamber 7c can be in fluid communication with the tanks 3hr1, 3hr2, 3hr3, and 3hr4. The atomization chamber 7c may be in fluid communication with the grooves 3vr1, 3vr2, 3vr3, and 3vr4.

The fluid in the storage compartment 30 can enter the atomization chamber 7c through a plurality of grooves on the upper cover 3 of the heating assembly along the path 3f1. The fluid in the atomization chamber 7c can enter the storage compartment 30 through a plurality of slots on the upper cover 3 of the heating assembly along the path 3f1. The fluid referred to here can be liquid or gas.

After the cartridge 100A is assembled, the pressure in the storage compartment 30 may change due to temperature or the external environment. If the pressure in the storage compartment 30 is too large, too much e-liquid may reach the heating assembly 5 through the openings 3h2 and 3h3 of the upper cover 3 of the heating assembly. When the volume of the e-liquid reaching the heating assembly 5 exceeds the upper limit that the heating assembly 5 can absorb, the e-liquid in the storage compartment 30 will easily drip through the heating assembly 5 into the atomization chamber 7c. Excessive liquid in the atomizing chamber 7c will increase the probability of e-liquid leakage from the cartridge 100A.

In addition, during the continuous use of the atomization device 100, the e-liquid in the storage compartment 30 continues to decrease, which may generate negative pressure in the storage compartment 30. The negative pressure in the storage compartment 30 may make it difficult for e-liquid to reach the heating assembly 5 from the openings 3h2 and 3h3 of the upper cover 3 of the heating assembly. In the case that the amount of e-liquid adsorbed by the heating assembly 5 is insufficient, the high-temperature heating assembly 5 may produce a burnt smell, resulting in a bad user experience and reducing the service life of the heating assembly 5.

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

The multiple grooves provided on the upper cover 3 of the heating assembly also have many other advantages. For example, due to the tortuous path between the grooves, the e-liquid entering the grooves from the storage compartment 30 will be contained in the grooves and will not directly enter the atomization chamber 7c. The multiple grooves provided on the upper cover 3 of the heating assembly can reduce the volume of e-liquid entering the atomization chamber 7c, and reduce the probability of the e-liquid leaking to the outside of the cartridge 100A.

The cartridge base 9 includes a plurality of grooves on the right side relative to the atomization chamber 7c. The cartridge base 9 includes a plurality of grooves on the left side relative to the atomization chamber 7c. The plurality of grooves provided on the upright walls 9w1 and 9w2 of the cartridge base 9 can become fluid channels. 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, the fluid can follow the path 9f1 from the atomization chamber 7c to the groove 3vr4 on the upper cover 3 of the heating assembly via the groove on the upright wall 9w2. The fluid can follow the path 9f1 from the groove 3vr4 on the upper cover 3 of the heating assembly to the atomization chamber 7c via the groove on the upright wall 9w2.

As shown in FIG. 5B, the fluid in the storage compartment 30 can enter the atomization chamber 7c through a plurality of grooves on the upper cover 3 of the heating assembly along the path 3f2. The fluid in the atomization chamber 7c can enter the storage compartment 30 through a plurality of grooves on the upper cover 3 of the heating assembly along the path 3f2. The fluid can follow the path 9f2 from the atomization chamber 7c to the groove 3vr4 on the upper cover 3 of the heating assembly via the groove on the upright wall 9w2. The fluid can follow the path 9f2 from the groove 3vr4 on the upper cover 3 of the heating assembly to the atomization chamber 7c via the groove on the upright wall 9w2.

The multiple slots provided on the upright walls 9w1 and 9w2 of the cartridge base 9 also have many other advantages. For example, due to the tortuous path between the grooves, the e-liquid entering the grooves from the storage compartment 30 will be contained in the grooves and will not directly enter the atomization chamber 7c. The multiple grooves provided on the upright walls 9w1 and 9w2 of the cartridge base 9 can reduce the volume of e-liquid entering the atomization chamber 7c and reduce the probability of the e-liquid leaking to the outside of the cartridge 100A.

Referring to FIGS. 5A and 4D, the upper cover sealing assembly 2 covers the upper cover 3 of the heating assembly after the cartridge 100A is assembled. The gas in the atomization chamber 7c can reach the junction of the opening 3h3 of the upper cover 3 of the heating assembly and the opening 2h3 of the upper cover sealing assembly 2 along the path 3f2. The gas that reaches the opening 2h3 of the upper cover sealing assembly 2 along the 3f2 path can cause the upper cover sealing assembly 2 to locally deform. The gas that reaches the opening 2h3 of the upper cover sealing assembly 2 along the path 3f2 can create a gap between the upper cover sealing assembly 2 and the upper cover 3 of the heating assembly, allowing the gas to enter the storage compartment 30 through the opening 2h3.

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

The back surface of the upper cover 3 of the heating assembly has grooves 3vr6 and 3vr7 extending along the vertical direction. Slot 3vr6 connects slot 3hr2 and slot 3hr3. Tank 3vr7 communicates with tank 3hr4. Comparing FIGS. 5A and 5C, it can be seen that different numbers of vertical grooves can be provided on the front and back of the upper cover 3 of the heating element. In some embodiments, the number of vertical grooves provided on the front surface of the upper cover 3 of the heating element is relatively large.

In some embodiments, the main body 100B can supply power to the cartridge 100A. The main body 100B may include a conductive component 11, a magnetic component 12, a sensor 13, a sealing kit 13a, a light guide frame 14, a main circuit board 15, a vibrator 17, a

magnetic guide

18a, 18b, a charging guide 19, a power supply component 20, and a power supply. The component bracket 21, the main body housing 22, the charging circuit board 23, the adjusting circuit 24, and the port 25.

The main body shell 22 has an opening 22h and a cavity 22c. The power supply bracket 21 is disposed in the cavity 22c of the main body housing 22 through the opening 22h of the main body housing 22. The surface of the main body housing 22 has a light-transmitting component 221. The plurality of light-transmitting components 221 can be surrounded to form a specific shape or pattern, such as a circle. The light-transmitting component 221 may be a through hole. The material of the main body shell 22 may be metal to improve the overall strength of the atomization device 100. For example, the material of the main body shell 22 may be aluminum to reduce the overall weight.

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

As demonstrated in FIG. 7, the atomization device 100 can be accommodated in a accommodating device 200. For example, the accommodating device 200 may have a accommodating groove 210, and the accommodating groove 210 may be used for accommodating the atomization device 100. On the other hand, in some embodiments, the accommodating device 200 can be used for a charging function to charge the atomizing device 100. In some embodiments, the accommodating device 200 may include a magnetic attraction component 220, and the magnetic attraction component 220 is disposed under one end of the accommodating groove 210.

In some embodiments, the central axis normal line L3 extending from the top surface 222 of the magnetic attraction assembly 220 does not penetrate the

magnetic guides

18a, 18b of the atomization device 100, and the top surface 222 of the magnetic attraction assembly 220 is adjacent to The tangent line L4 of the side 224 of the atomization device 100 penetrates through the

magnetic guides

18a and 18b corresponding to the main body 100B of the atomization device 100. In other words, the

magnetic guide members

18a and 18b are closer to the middle area of the receiving device 200 than the magnetic attraction component 220 is. For example, when the top surface 222 of the magnetic attraction component 220 is N pole, the end surface 18c of the magnetic guide 18a facing the atomization device 100 (opposite to the direction of the cartridge 100A) is the S pole, and the magnetic guide 18b faces the fog. The end surface 18d outside the chemical device 100 (in the direction opposite to the cartridge 100A) is an N pole. Since the top surface 222 of the magnetic attraction assembly 220 and the magnetic guide member 18a closer to each other of the

magnetic guide members

18a and 18b are attracted to each other, the atomization device 100 can be correctly set in the designated position of the accommodating device 200. Since the top surface 222 of the magnetic attraction assembly 220 and the farther magnetic guide 18b of the

magnetic guides

18a and 18b mutually repel each other, it can prevent the magnetic guide 18a from causing the opposite side of the atomization device 100 (ie The end edge of the cigarette holder cover 1 of the cigarette cartridge 100A is cocked or popped open. Therefore, the magnetic guide 18b has the effect of stably setting the atomization device 100 in the accommodating device 200.

In some embodiments, if the charging box or the charging stand corresponding to the atomizing device 100 does not have opposite polarity (electrode polarity), the adjustment circuit 24 (see FIG. 6) on the charging circuit board 23 can be configured to The current from the charging guide 19 is adjusted to complete the charging. Therefore, regardless of whether the atomizing device 100 is inserted into the charging box or the charging dock in the forward or reverse direction, the adjustment circuit 24 can be configured to adjust the charging current to complete the charging of the atomizing device 100. For example, assuming that power is provided to the first power input point P1 (not shown in the figure) and the second power input point P2 (not shown in the figure) of the charging circuit board 23 through the charging guide 19, the second power input point P2 (not shown in the figure) of the charging circuit board 23 is One circuit output T1 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 the positive power supply and the second power input point P2 receives the power input as the negative power supply, by adjusting the configuration of the switch circuit module of the circuit 24, the output of the first circuit can be made The point T1 (not shown in the figure) is the positive pole, and the second circuit output point T2 (not shown in the figure) is the negative pole. In the second case, when the power input received by the power input point P1 is the negative power supply, and the power input received by the second power input point P2 is the positive power supply, the configuration of the switch circuit module of the circuit 24 can be adjusted The output point T1 of the first circuit is adjusted to be positive, and the output point T2 of the second circuit is adjusted to be negative. Therefore, no matter how the polarity of the first power input point P1 and the second power input point P2 changes, the first circuit output point T1 and the second circuit output point T2 always maintain a fixed output polarity through the adjustment circuit 24, and power is supplied to the lower level Circuits, such as the power supply assembly 20 and/or the main circuit board 15.
