Technical Field

The present application relates generally to electronic devices, and more particularly to a nebulizing device (aerosol) for providing an inhalable 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 reservoir will cause a large amount of tobacco tar to flow towards the heating assembly and may cause problems with the leakage of tobacco tar 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.

The existing electronic cigarette product does not consider the relative position between the heating component and the air inlet channel, and cold air entering the atomizing device from the air inlet channel can directly blow the heating component, so that the heating efficiency of the heating component is reduced, and the power loss is increased. In addition, the condensed liquid in the existing electronic cigarette product often leaks through the air inlet channel, which contaminates the clothes or personal belongings of the user and causes bad user experience.

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

The heating assembly top cover 3 has a notch 3b1 on one side and a notch 3b2 on the other side. The notch 3b1 and the notch 3b2 face in different directions. For example, as shown in fig. 3B, notch 3B1 faces forward and notch 3B2 faces rearward. For example, as shown in fig. 5A, the notch 3b1 faces in the direction of axis z1 and the notch 3b2 faces in the direction of axis z 2. The axis z1 is perpendicular to the axes x and y. The axis z2 is perpendicular to the axes x and y.

Notches 3b1 and 3b2 facing in different directions have advantages. When the user holds the atomization device 100 in a horizontal orientation (i.e., the atomization device 100 is parallel to the ground), at least one of the notch 3b1 and the notch 3b2 faces upward (i.e., faces in the opposite direction of the ground). Therefore, even if the condensed liquid remains in the cartridge 100A, at least one of the notch 3b1 and the notch 3b2 is not clogged with the condensed liquid. The notches 3b1 and 3b2 are part of separate air passages to ensure pressure equalization in the storage compartment of the cartridge 100A. In subsequent paragraphs, the individual airway features will be described in detail in conjunction with other figures of this document.

Notch 3b2 is in fluid communication with grooves 3hr1, 3hr2, 3hr3, 3vr1 and opening 3h 5.

The opening 3h4, the opening 3h5 and the groove formed on the side of the heating element top cover 3 can be used as an air passage for balancing the pressure between the storage chamber (for storing the tobacco tar) and the atomizing chamber. The function of the air passage formed by the opening 3h4 and the opening 3h5 will be described in the following paragraphs with reference to fig. 6A.

The heating element top cover 3 further has a plurality of grooves 3vr2 and 3vr 3. The provision of a plurality of grooves 3vr2 and 3vr3 in the heating element top cover 3 has a number of advantages. When the aerosolization device 100 is continuously used, aerosol in the aerosolization chamber 6c that is not completely ingested by the user may condense into liquid and remain in the cartridge 100A. The condensed liquid within the cartridge 100A may adhere to the grooves 3vr2 and 3vr 3. The grooves 3vr2 and 3vr3 can adsorb condensed liquid. Thus, the grooves 3vr2 and 3vr3 reduce the chance of condensed liquid leaking from within the cartridge 100A.

As shown in fig. 5B, the heating element mount 6 may include grooves 6vr1, 6vr2, and 6vr3 extending in a vertical direction (e.g., along the y-axis direction). Grooves 6vr1, 6vr2 and 6vr3 function similarly to grooves 3vr2 and 3vr 3. The condensed liquid within the cartridge 100A may adhere to the grooves 6vr1, 6vr2, and 6vr 3. The grooves 6vr1, 6vr2 and 6vr3 can adsorb condensed liquid. Thus, the grooves 6vr1, 6vr2, and 6vr3 reduce the chance of condensed liquid within the cartridge 100A leaking.

The heating element base 6 may also include grooves 6hr1, 6hr2, 6hr3, and 6hr4 (not shown) extending in a horizontal direction (e.g., along the x-axis). The recess 6hr1 and the recess 6hr4 may be disposed at the junction of the support structure 6w1 and the heating element base 6. The recess 6hr2 and the recess 6hr3 may be disposed at the junction of the support structure 6w2 and the heating element base 6.

Grooves 6hr1, 6hr2, 6hr3 and 6hr4 function similarly to grooves 3vr2 and 3vr 3. The condensed liquid within cartridge 100A may adhere to grooves within 6hr1, 6hr2, 6hr3, and 6hr 4. The grooves 6hr1, 6hr2, 6hr3 and 6hr4 can absorb the condensed liquid. Thus, the grooves 6hr1, 6hr2, 6hr3, and 6hr4 reduce the chance of condensed liquid leaking from within the cartridge 100A.

In some embodiments, the heating assembly base 6 may contain a greater number of grooves. In some embodiments, the heating assembly base 6 may contain a smaller number of grooves.

Reference is now made to fig. 5C and 5D. The air inlet pipe 11a and the air inlet pipe 11b are respectively arranged at two sides of the heating component base 6. The air inlet tube 11a is adjacent to the support structure 6w 1. The air inlet pipe 11b is adjacent to the support structure 6w 2. The air inlet duct 11a is adjacent below the support structure 6w 1. The air inlet pipe 11b is adjacent to and below the support structure 6w 2. The intake pipe 11a is disposed along the axis 9x 1. The intake pipe 11b is disposed along the axis 9x 2. The axis 9x1 does not extend through the heating assembly 5. The axis 9x2 does not extend through the heating assembly 5.

The relative position of the inlet duct 11a and the heating assembly 5 as described above has a number of advantages. The relative position of the inlet duct 11b and the heating assembly 5 as described above has many advantages.

First, when the user inhales the cartridge 100A, the cool air introduced into the atomizing chamber 6c through the air inlet pipe 11a or the air inlet pipe 11b does not directly blow the heating element 5, thereby preventing the heating efficiency of the heating element 5 from being lowered.

Further, since the heating element 5 directly contacts the tobacco tar and adsorbs the tobacco tar, the heating element 5 becomes the element most likely to cause oil leakage in the cartridge 100A. The air inlet pipe 11a is arranged to avoid the heating assembly 5, so that the tobacco tar dropped from the heating assembly 5 can be prevented from entering the air inlet pipe 11 a. The air inlet pipe 11b is arranged to avoid the heating assembly 5, so that the tobacco tar dropped from the heating assembly 5 can be prevented from entering the air inlet pipe 11 b.

Below the support structure 6w1, a wall 6s1 extending substantially in a horizontal direction and a wall 6s2 extending substantially in a vertical direction are included. The wall 6s1 and the wall 6s2 are located around the top end of the intake pipe 11 a.

The wall 6s1 may include a curvature. The wall 6s1 may include a curved surface. Wall 6s1 and wall 6s2 have an interface 6u 1. The aerosol in the nebulization chamber 6c may condense on the wall 6s1 and form a liquid. When the user holds the atomizing device 100 vertically, the wall 6s1 may concentrate condensed liquid adsorbed on the wall 6s1 at the interface 6u 1. Condensed liquid adsorbed on the wall 6s1 may flow down the interface 6u1 to the wall 6s2 (e.g., similar to the arrow 6f2 drawn below the support structure 6w 2).

The position of the boundary 6u1 avoids the top end opening of the intake pipe 11 a. As shown in fig. 5C, the junction 6u1 is disposed along the axis 6x1, and the extending direction of the axis 6x1 does not pass through the intake pipe 11 a. The position of the interface 6u1 described above has advantages. Even if the liquid adsorbed on the wall 6s1 drops from the boundary 6u1 in an excessive amount, the dropped liquid does not enter the intake pipe 11a or 11 b. The chance of condensed liquid leaking from the cartridge 100A is reduced.

Referring to fig. 5D, the inner diameter of the intake pipe 11a is 11w1, and the inner diameter of the intake pipe 11b is 11w 2. In certain embodiments, the inner diameter 11w1 of the inlet tube 11a is the same as the inner diameter 11w2 of the inlet tube 11 b. In certain embodiments, the inner diameter 11w1 of the inlet tube 11a is different than the inner diameter 11w2 of the inlet tube 11 b. In some embodiments, the gas flow into the atomizing chamber 6c can be adjusted by adjusting the inner diameter 11w1 and the inner diameter 11w 2.

The type of tar may affect the amount of aerosol that the heating assembly 5 can generate. The amount of aerosol generated by the heating element 5 may also be related to the volume of air entering the atomization chamber 6c from the air inlet tube 11a and the air inlet tube 11 b. In some embodiments, the inner diameters 11w1 and 11w2 may be adjusted according to the type of tobacco tar in the cartridge 100A. In some embodiments, one of the intake pipe 11a or the intake pipe 11b may be omitted. In some embodiments, only a single air inlet tube may be provided on the heating assembly base 6.

In some embodiments, the inner diameter 11w1 and the inner diameter 11w2 can be adjusted to achieve a predetermined "draw resistance". The "draw resistance" referred to herein represents the amount of resistance felt by the user when inhaling the cartridge 100A. When the "draw resistance" is large, the user will feel that it is harder to inhale. When the "draw resistance" is small, the user will feel less effort to inhale.

In certain embodiments, the inner diameter 11w1 and/or the inner diameter 11w2 may be 0.6 mm. In certain embodiments, the inner diameter 11w1 and/or the inner diameter 11w2 may be 0.8 mm. In certain embodiments, the inner diameter 11w1 and/or the inner diameter 11w2 may be 0.9 mm. In certain embodiments, the inner diameter 11w1 and/or the inner diameter 11w2 may be 1.0 mm. In certain embodiments, the inner diameter 11w1 and/or the inner diameter 11w2 may be 1.2 mm. In certain embodiments, the inner diameter 11w1 and/or the inner diameter 11w2 may be in the range of 0.6mm to 1.2 mm.

In some embodiments, the cross-sectional surfaces of the inlet pipes 11a and 11b may be circular. In some embodiments, the cross sections of the inlet pipes 11a and 11b may be rectangular. In some embodiments, the cross sections of the inlet pipes 11a and 11b may be triangular. In some embodiments, the cross-sectional surfaces of the inlet pipes 11a and 11b may be other suitable shapes.

Figure 6A illustrates a cross-sectional view of a cartridge according to some embodiments of the present application. Figure 6B illustrates a cross-sectional view of a cartridge according to some embodiments of the present application.

The mouthpiece cover 1a comprises a tubular structure 1a1 extending towards the heating assembly 5. The cartridge housing 1b contains a tube 1t extending from the opening 1h1 in the direction of the heating assembly 5. The junction of the tube 1t and the cartridge housing 1b has an inclined wall 1b 1. The tubular structure 1a1 of the mouthpiece cover 1a is in direct contact with the inclined wall 1b1 of the cartridge housing 1 b. The tubular structure 1a1 of the mouthpiece cover 1a engages with the inclined wall 1b1 of the cartridge housing 1b and has a sealing effect.

The cartridge 100A further includes a seal assembly 1 d. The sealing assembly 1d is arranged between the tubular structure 1a1 and the inclined wall 1b 1. A gap exists between the mouthpiece cover 1a and the cartridge housing 1b, and the sealing assembly 1d prevents the user from drawing in cool air from the gap during smoking. Furthermore, the sealing element 1d also prevents saliva or condensate from flowing from the gap between the mouthpiece cover 1a and the cartridge housing 1b to the cartridge housing 1b surface.

The cartridge housing 1b, tube 1t and sealing assembly 2 together define a storage compartment 50. The storage compartment 50 is used to hold tobacco tar. As shown in fig. 6A, the tobacco tar in the storage compartment 50 can flow to the heating element 5 through the openings 3h2 and 3h3 of the heating element top cover 3.

Airflow 6f3 and airflow 6f4 are shown in FIG. 6A. The gas flows 6f3 and 6f4 indicate that the gas in the atomization chamber 6c can enter the storage compartment 50 under certain circumstances.

When the atomizer 100 is not being sucked by the user while it is standing, the openings 3h4 and 3h5 are tightly coupled to the sealing member 2, and the tobacco tar in the storage chamber 50 does not leak out of the openings 3h4 and 3h 5.

As the user continues to use the atomizer, the tobacco tar in the storage compartment 50 is continuously consumed and reduced, causing the pressure in the storage compartment 50 to gradually decrease. A negative pressure may be generated when the pressure in the storage compartment 50 becomes lower. The reduced pressure in the storage compartment 50 may prevent the smoke from flowing to the heating element 5 through the openings 3h2 and 3h 3. When the heating element 5 does not completely adsorb the soot, the heating element 5 having a high temperature may dry burn and generate a scorched smell.

This problem is ameliorated by providing openings 3h4 and 3h5 in the heating element top cover 3 (and grooves in the sides of the heating element top cover 3). The openings 3h4 and 3h5 provided in the heating module top cover 3 (and the grooves on the sides of the heating module top cover 3) can equalize the pressure within the storage compartment 50. The opening 3h4 and the opening 3h5 provided in the heating assembly top cover 3 are in fluid communication with the atomizing chamber 6 c.

Since the atomization chamber 6c is in fluid communication with the inlet tubes 11a and 11b, the pressure in the atomization chamber 6c is approximately equal to one atmosphere. As the amount of soot in the reservoir 50 decreases, the pressure in the reservoir 50 gradually decreases to less than one atmosphere. The pressure difference between the atomization chamber 6c and the storage compartment 50 causes the airflow 6f3/6f4 to pass from the atomization chamber 6c through the recess in the side of the heating assembly lid 3 to the interface of the opening 3h 4/opening 3h5 and the sealing assembly 2.

Air flows 6f3 and 6f4 may partially push seal assembly 2 apart. The gas flows 6f3 and 6f4 may partially deform the seal assembly 2. The air flows 6f3 and 6f4 can enter the storage compartment 50 through the gap created by the deformation of the sealing assembly 2. The streams 6f3 and 6f4 entering storage compartment 50 can cause the pressure in storage compartment 50 to rise. The air flows 6f3 and 6f4 entering the reservoir 50 can equalize the pressure between the reservoir 50 and the atomization chamber 6 c.

The tapered inner walls of opening 3h4 may make it easier for air flow 6f3 to push seal assembly 2 away. The tapered inner walls of opening 3h5 may make it easier for air flow 6f4 to push seal assembly 2 away.

Reference is now made to fig. 6B. The airflow 6f1 is shown in fig. 6B. The aerosol generated by the heating element 5 can enter the tube 1t inside the cartridge housing 1b via the channel 3t1 and the channel 3t2 of the heating element top cover 3. The aerosol generated by the heating element 5 can reach the opening 1h1 via the tube 1t and be inhaled by the user.

Fig. 7A illustrates an exploded view of a heating assembly base according to some embodiments of the present application. Fig. 7B and 7C illustrate cross-sectional views of a heating element base according to some embodiments of the present application.

The heating assembly base 28 has some similar features to the heating assembly base 6. The heating assembly base 28 has several different features from the heating assembly base 6. The heating assembly base 28 may be used in place of the heating assembly base 6 in the cartridge 100A. When the heating assembly base 28 is used in the cartridge 100A, the air inlet duct 11a and the air inlet duct 11b in the cartridge 100A may be omitted.

The heating element base 28 may be configured with other elements. As shown in fig. 7A, the heating element base 28 includes a support structure 28w1 and a support structure 28w 2. A wicking assembly 29a may be disposed in a recess 28r1 below the support structure 28w 1. A wicking assembly 29b may be disposed in recess 28r2 below support structure 28w 2.

The atomizing device 100 may topple over during use/carrying, and the wicking assembly 29a may absorb liquid flowing through the recess 28hr1 toward the recess 28r 1. The atomizing device 100 may topple over during use/carrying, and the wicking assembly 29b may absorb liquid flowing through the recess 28hr2 toward the recess 28r 2. The liquid referred to herein may be soot that leaks from the heating element 5 or may be a condensate that is generated after condensation of the aerosol.

The wicking assembly 29a can reduce the chance of smoke or condensate leaking from the cartridge 100A. The wicking assembly 29b can reduce the chance of smoke or condensate leaking from the cartridge 100A.

In certain embodiments, wicking assembly 29a and wicking assembly 29b can comprise cotton. In certain embodiments, absorbent assembly 29a and absorbent assembly 29b may comprise nonwoven fabrics. In some embodiments, absorbent assembly 29a and absorbent assembly 29b may comprise polymeric materials that are capable of absorbing liquids. In certain embodiments, absorbent assembly 29a and absorbent assembly 29b may comprise at least two of cotton, nonwoven, or high molecular weight polymeric materials.

The bottom of the heating assembly base 28, between the support structure 28w1 and the support structure 28w2, may include an air intake structure 28 c. The air intake structure 28c may include a plurality of openings 28 h. A plurality of openings 28h extend through the air inlet structure 28c to form air flow passages.

The air intake structure 28c has an upper surface 28 s. The upper surface 28s is not a flat surface. The upper surface 28s has a curvature. The curvature of the upper surface 28s is convex in the direction of the heating element 5. Liquid on the inlet structure 28c will flow downwardly along the curvature of the upper surface 28 s. The curvature of the upper surface 28s may reduce the chance of liquid remaining in the air intake structure 28 c. The curvature of the upper surface 28s can reduce the chance of liquid leaking from the opening 28 h.

As shown in fig. 7A, the heating element base 28 may further include a cover 30 disposed over the air intake structure 28 c. The cover 30 has a plurality of openings 30 h. The opening 30h allows airflow to pass through.

The bottom of the heating assembly base 28 has a recess 28t, which 28t may accumulate smoke or condensation as the user continues to use the cartridge 100A. The cover 30 is higher than the air intake structure 28c, and the cover 30 may further reduce the chance of liquid leaking from the air intake structure 28 c. As shown in fig. 7B, the upper surface 30s of the cover 30 is spaced from the upper surface 28s of the air intake structure 28c by a distance d 1. The cover 30, which is higher than the air inlet structure 28c, prevents liquid accumulated in the recess 28t from entering the opening 28h of the air inlet structure 28 c.

In some embodiments, the cover 30 may comprise a metal material. In some embodiments, the cover 30 may be made of a metal material. In some embodiments, the cover 30 may comprise a plastic material. In some embodiments, the cover 30 may be made of a plastic material.

Figure 8 shows a cross-sectional view of the cartridge 100A'. The cartridge 100A' has some of the same features as the cartridge 100A. The cartridge 100A' has many different features than the cartridge 100A.

Comparing the cartridge 100A shown in fig. 6A with the cartridge 100A 'shown in fig. 8, the cartridge 100A uses the heating assembly base 6 and the cartridge 100A' uses the heating assembly base 28.

Fig. 8 shows the airflows 28f1 and 28f2 for the cartridge 100A'. The airflow 28f1 enters the cartridge 100A' from the opening 1c1, the opening 28h and the opening 30h of the cartridge bottom lid 1 c. The airflow 28f2 enters the cartridge 100A' from the opening 1c1, the opening 28h and the opening 30h of the cartridge bottom lid 1 c. In the cartridge 100A shown in fig. 6A, cool air enters the cartridge 100A through the intake duct 11a and the intake duct 11 b. The cartridge 100A 'shown in fig. 8, cool air enters the cartridge 100A' via the air intake structure 28 c.
