Description

Atomization device

Technical Field

The present disclosure relates generally to nebulizing devices (nebulizing devices), and more particularly to electronic devices for providing an inhalable aerosol (aerosol).

Background

An electronic cigarette is an electronic product that heats and atomizes an nebulizable solution and generates an aerosol for a user to inhale. In recent years, various electronic cigarette products have been produced by large manufacturers. Generally, an electronic cigarette product includes a housing, an oil chamber, an atomizing chamber, a heating element, an air inlet, an air flow channel, an air outlet, a power supply device, a sensing device and a control device. The oil storage chamber is used for storing an aerosolizable solution, and the heating assembly is used for heating and atomizing the aerosolizable solution and generating an aerosol. The air inlet and the aerosolizing chamber communicate with one another to provide air to the heating assembly when a user inhales. The aerosol generated by the heating element is first generated in the aerosolizing chamber and then inhaled by the user via the air flow passage and the air outlet. The power supply device provides the electric power required by the heating component, and the control device controls the heating time of the heating component according to the user inspiration action detected by the sensing device. The shell covers the above components.

In the manufacturing process of electronic cigarettes, tobacco tar is generally injected and then sealed. However, the sealed tobacco tar container is easy to cause tobacco tar leakage in the subsequent assembly process, and the quality of the product is difficult to control. And the sealed tobacco tar container is easy to leak due to temperature change in the conveying process, so that the yield of products is influenced.

During use of the e-cigarette by a user, the generated aerosol may condense into a liquid in the respective cavity or channel. For example, the aerosol may condense to form a liquid in a cavity or passage such as an aerosolization chamber, an air inlet, an air flow passage, or an air outlet. The liquid in the cavities or channels may leak during use of the e-cigarette by a user. In addition, the oil smoke may leak if not stored properly. Such leakage can contaminate the user's clothing, pants, or other valuables being carried around, thereby creating a poor user experience.

During the use of the electronic cigarette by the user, the tobacco tar is heated by the heating component to generate the aerosol. If the current can not pass through the heating component, the heating component can not generate the aerial fog. In addition, if the tobacco tar can not reach the heating component smoothly, the heating component can not generate aerial fog. Failure to produce aerosol can create a poor user experience.

Along with the continuous improvement of the use frequency, how to reduce the assembly cost of the electronic cigarette and make the electronic cigarette better satisfy the requirements of the user so as to improve the user experience is an indispensable link for the development of the electronic cigarette.

Accordingly, an atomizing device capable of solving the above problems is provided.

When the interference amount is 0.15mm to 0.25mm, the sealing effect is better. When the interference amount is less than 0.1mm, soot may leak.

In fig. 12C and 12D, in the combination of seal assembly 13, carrier 14 and housing 11, air vent 14v2 forms a fluid path between upper portion 14tp of carrier 14 and groove 13gr 2. When the tobacco tar is atomized and inhaled by the user, the pressure of the storage compartment 11ca may become small and the tobacco tar may not easily flow to the recess 16 ca. The air vent 14v2 balances the pressure in the storage compartment 11ca (shown in fig. 12A) for storing the tobacco tar with the pressure outside the housing 11 via the slit between the seal member 13 and the bracket 14 and via the slit between the seal member 13, the bracket 14 and the housing 11.

In fig. 12D, the seal assembly 15 includes a ring structure 15 r. The ring structure 15r is disposed in the hole 15h 1. The annular structure 15r is provided on the stepped inner surface of the hole 15h 1. The ring structure 15r protrudes from the inner surface of the hole 15h 1. The ring structure 15r protrudes downward. The top surface area of the ring structure 15r is smaller than the bottom surface area thereof. The longitudinal section of the ring-shaped structure 15r is in the shape of a trapezoid or a triangle with an upper base smaller than a lower base. When the heating element 16 is combined with the sealing element 13, the bracket 14 and the sealing element 15, the top surface of the heating element 16 abuts against the annular structure 15 r. In some embodiments, when the heating element 16 is combined with the sealing element 13, the bracket 14, and the sealing element 15, the top surface of the heating element 16 compresses and interferes with the annular structure 15r to form a liquid or gas seal. When the interference amount is 0.15mm to 0.25mm, the sealing effect is better. When the interference amount is less than 0.1mm, soot may leak.

In fig. 12D, when the heating element 16 is combined with the sealing element 13, the bracket 14, and the sealing element 15, the hole 15h1 surrounds the heating element 16. The heating element 16 abuts the inner surface of the hole 15h 1. The hole 15h1 surrounds the flange 16f of the heating element 16. The flange 16f of the heating element 16 abuts against the inner surface of the hole 15h 1. In some embodiments, the flange 16f of the heating element 16 creates a groove and an amount of interference at the corresponding location of the inner surface of the aperture 15h1 to form a liquid or gas seal. When the interference amount is 0.15mm to 0.25mm, the sealing effect is better. When the interference amount is less than 0.1mm, soot may leak.

In fig. 12D, storage compartment 11ca, aperture 13h2, aperture 14h2, aperture 15h1, and recess 16ca are in fluid communication. In fig. 12D, storage compartment 11ca, port 13h1, port 14h1, and port 15h2 are in fluid communication. In fig. 12D, opening 14g3, opening 15g1, and opening 15g2 are in fluid communication. In fig. 12D, opening 14g3, opening 15g1, opening 15g2 are not fluidly connected to storage compartment 11ca, hole 13h2, hole 14h2, hole 15h1, and recess 16 ca. In fig. 12D, opening 14g3, opening 15g1, opening 15g2 are not fluidly connected to storage compartment 11ca, hole 13h1, hole 14h1, and hole 15h 2.

During the assembly process of the cartridge 10, the storage compartment 11ca is filled with the tobacco tar to be atomized. In some embodiments, the tobacco tar may be poured into the storage compartment 11ca in the state of fig. 12C or fig. 12D. In some embodiments, the tobacco tar may be filled into the storage compartment 11ca from the hole 15h2 on one side through the hole 14h1 and the hole 13h1 on the same side in the state of fig. 12C or fig. 12D; the holes 15h2, 14h1, and 13h1 on the other side can balance the internal and external pressure of the storage chamber 11ca during the period of tobacco tar filling. In some embodiments, in the state of fig. 12C or 12D, a fluid passage through which the tobacco tar is filled into the storage compartment 11ca includes the hole 15h2, the hole 14h1, and the hole 13h1 on the same side; the other fluid passage includes the hole 15h2, the hole 14h1 and the hole 13h1 on the other side, and the other fluid passage can balance the internal and external pressures of the storage chamber 11ca during the period of the tobacco tar filling.

Fig. 12E shows housing 11, wicking assembly 12, sealing assembly 13, carrier 14, sealing assembly 15, heater assembly 16, and base 17. Referring to fig. 12E, base 17 is assembled from below and up with housing 11, wicking assembly 12, sealing assembly 13, carrier 14, sealing assembly 15, and heater assembly 16 (as shown in fig. 12C). The flange 17f1 of the base 17 abuts the inner surface of the outer wall 11w of the housing 11 to form a liquid or gas seal. The material of the base 17, except for the spring plate 17s, the contact 17c1 and the magnetic member 17m, is mostly hard plastic, such as polypropylene (PP) or Polyethylene (PE), but other suitable materials may be selected according to the actual situation, and the material is not limited thereto. The flange 17f2 of the base 17 abuts against the lower edge of the outer wall 11w of the housing 11. The post 17c of the base 17 is inserted into the hole 15h2 and the hole 14h 1. Post structure 17c passes through aperture 15h2 of seal assembly 15. The aperture 15h2 of the seal assembly 15 surrounds a portion of the post structure 17 c. Post 17c of base 17 will be inserted into aperture 15h2 such that aperture 13h1 is not in fluid communication with aperture 14h 1.

Fig. 12F is a partial enlarged view of fig. 12E. When base 17 is combined with housing 11, wicking assembly 12, sealing assembly 13, carrier 14, sealing assembly 15, and heating assembly 16 as shown in FIG. 12C, the top of post 17C is approximately at aperture 14h 1. The post 17c of the base 17 is inserted into the hole 15h2 and the hole 14h 1. Post structure 17c passes through aperture 15h2 of seal assembly 15. The aperture 15h2 of the seal assembly 15 surrounds a portion of the post structure 17 c. Post 17c of base 17 will be inserted into aperture 15h2 such that aperture 13h1 is not in fluid communication with aperture 14h 1. Since the post 17c of the base 17 is to be inserted into the hole 15h2 and the hole 14h1, the storage chamber 11ca is not in fluid communication with the hole 15h 1. The storage compartment 11ca is in fluid communication with the aperture 13h2, the aperture 14h2, the aperture 15h1, and the recess 16ca of the heating assembly 16. Opening 14g2 and opening 14g1 are not in fluid communication with storage compartment 11 ca.

Fig. 12G is a partially enlarged view of fig. 12E. Opening 17g2, fluid passage 17gc are in fluid communication with opening 17g 1. Via opening 15G1, opening 14G3, and fluid passage 14gc (not shown in fig. 12G), opening 14G2 may be in fluid communication with opening 17G2, fluid passage 17gc, and opening 17G 1. The magnetic elements 17m may be magnetically attached to corresponding magnetic elements (not shown) of the tobacco rod. When the magnetic element 17m is magnetically attached to a corresponding magnetic element of the tobacco rod, the cartridge 10 can be correctly positioned to the tobacco rod. The contact 17c1 may be in contact with a conductive element (not shown) of the tobacco rod. The energy from the battery of the tobacco rod is transferred to the contact 17c1, the spring plate 17s and the heating element 16 via the conductive element in contact with the contact 17c 1. The contact 17c1 may be formed by a portion 17s1 of the spring plate 17 s.

Referring to FIG. 12G, when base 17 is combined with housing 11, wicking assembly 12, sealing assembly 13, carrier 14, sealing assembly 15, and heater assembly 16 as shown in FIG. 12C, posts 17C will cause the inner surfaces of apertures 15h2 of sealing assembly 15 to be squeezed and generate an interference amount to form a liquid or gas seal. When the interference amount is 0.15mm to 0.25mm, the sealing effect is better. When the interference amount is less than 0.1mm, soot may leak.

After the tobacco tar is filled in the storage compartment 11ca in the state of fig. 12C, the base 17 is combined with the housing 11, the liquid suction unit 12, the sealing unit 13, the bracket 14, the sealing unit 15, and the heating unit 16 shown in fig. 12C. In the state of fig. 12E, the tobacco tar stored in the storage compartment 11ca cannot flow out through the hole 13h1, the hole 14h1 and the hole 15h2 any more. In the state of fig. 12E, the tobacco tar stored in the storage compartment 11ca can flow only to the recess 16ca of the heating element 16 through the hole 13h2, the hole 14h2, and the hole 15h1, and the heating element 16 adsorbs the tobacco tar for heating and atomization. In the state of fig. 12E, the storage compartment 11ca is in fluid communication with the hole 13h2, the hole 14h2, the hole 15h1, and the recess 16 ca.

In some embodiments, if the seal assembly 25 shown in figure 7A is substituted for the seal assembly 15 shown in figure 12E, the assembled cartridge may not include the flange 15f3 shown in figure 12G. However, because of the flange 17f1, flange 13f1, and other flanges, the cartridge 10 is sealed against stored tobacco smoke and inhaled gases even without the flange 15f 3.

Fig. 13A and 13B are cross-sectional views of cartridges 10 according to some embodiments of the present application. The housing 11 may be similar to a flat and long column. The mouthpiece cover 11m is in contact with the mouth of the user of the electronic cigarette. The flat housing 11 or the nozzle cover 11m can correspond to the shape of the user's mouth so that the user can easily hold the nozzle cover 11 m. The hole 11h of the housing 11 is engaged with the protrusion 17p of the base 17. The flange 17f2 of the base 17 abuts against the lower edge of the housing 11. The flange 17f2 of the base 17 abuts against the lower edge of the outer wall 11w of the housing 11.

The storage compartment 11ca is in fluid communication with the recess 16ca of the heating element 16 via the hole 13h2, the hole 14h2, and the hole 15h 1. The tobacco tar stored in the storage compartment 11ca flows to the recess 16ca of the heating element 16 through the hole 13h2, the hole 14h2, and the hole 15h1, so that the heating element 16 adsorbs the tobacco tar for heating and atomization.

Opening 11g is in fluid communication with fluid passage 11gc, wicking assembly 12, and opening 14g 1. Opening 17g2 is in fluid communication with opening 17g 1. Opening 17g1 is in fluid communication with opening 14g1 via opening 15g2, opening 15g1, opening 14g3, fluid passage 14gc and opening 14g2 (not shown in fig. 13A). When a user inhales from the opening 11g, external air flows from the fluid passage 17gc (not shown in fig. 13A) and the opening 17g2 to the opening 17g 1. The external air mixes with the atomized tobacco tar at the opening 15g2 (not shown in fig. 13A), flows to the opening 15g1, the opening 14g3, the fluid passage 14gc and the opening 14g2 (not shown in fig. 13A), flows to the opening 14g1 and the fluid passage 11gc, and is inhaled by the user at the opening 11 g.

Referring to fig. 13B, opening 17g1 is in fluid communication with opening 15g2, opening 15g1, and opening 14g 3. In some embodiments, the space below the heating element 16 and between the openings 17g1 and 15g2 may be referred to as an atomizing chamber. In some embodiments, the space below the contact 16c of the heating element 16 and the heating circuit 16hc and between the openings 17g1 and 15g2 may be referred to as an atomization chamber. The gas inhaled from the outside is mixed with the atomized tobacco tar in the atomization chamber. When a user inhales from the opening 11g (not shown in fig. 13B), external air flows from the fluid passage 17gc (not shown in fig. 13B) and the opening 17g2 (not shown in fig. 13B) to the opening 17g 1. The external air is mixed with the atomized tobacco tar at the opening 15g2 (or the atomizing chamber), flows to the opening 15g1, the opening 14g3, the fluid passage 14gc (not shown in fig. 13B) and the opening 14g2 (not shown in fig. 13B), flows to the opening 14g1 (not shown in fig. 13B) and the fluid passage 11gc (not shown in fig. 13B), and is finally inhaled by the user at the opening 11g (not shown in fig. 13B).

Referring to FIG. 13B, the spring plate 17s is used to conduct current to the contact 16c of the heating element 16 to raise the temperature of the heating element 16. The spring pieces 17s are formed of a conductive material. The contact 17c1 is in electrical communication with the spring plate 17 s. In some embodiments, the contact 17c1 and the spring plate 17s are formed from a single conductive element. In some embodiments, the contact 17c1 is formed by a portion of the spring plate 17 s. The area of contact 17c1 is defined by the diameter of hole 17h 1. The contact 17c1 may be in contact with a conductive element (not shown) of the tobacco rod. The energy from the battery of the tobacco rod is transferred to the contact 17c1, the spring plate 17s and the heating element 16 via the conductive element in contact with the contact 17c 1. The energy of the battery is transmitted to the contact 16c of the heating element 16 and the heating circuit 16hc via the contact 17c1 and the spring plate 17s to heat and atomize the tobacco tar adsorbed by the heating element 16.

In some embodiments, the height of the spring plate 17s is compressed when the base 17 is combined with the housing 11, wicking assembly 12, sealing assembly 13, carriage 14, sealing assembly 15, and heating assembly 16 into the cartridge 10. Since the height of the spring piece 17s is pressed, the spring piece 17s generates a force applied to the heating element 16 so that the spring piece 17s closely abuts against the contact 16c of the heating element 16. The spring piece 17s closely contacts the contact 16c of the heating element 16, so that the chance of poor contact or disconnection between the spring piece 17s and the heating element 16 can be reduced.

Referring to fig. 5A, the carriage 14 includes an air vent 14v1 and a fluid passage 14 vp. The fluid passage 14vp is in fluid communication with the air vent 14v1 and the fluid passage 14 gc. When the tobacco tar is atomized and inhaled by the user, the pressure of the storage compartment 11ca may become small and the tobacco tar may not easily flow to the recess 16 ca. Referring to fig. 13B, when the external air flows from the fluid passage 17gc (not shown in fig. 13B) and the opening 17g2 (not shown in fig. 13B) to the opening 17g1, and the external air flows to the opening 15g1, the opening 14g3, the fluid passage 14gc (not shown in fig. 13B) after being mixed with the atomized soot at the opening 15g2 (or the atomizing chamber), the pressure of the storage compartment 11ca can be equalized with the external pressure through the fluid passage 14vp and the air hole 14v1 which are in fluid communication with the fluid passage 14 gc.

Fig. 14A and 14B are schematic views of gas channels according to some embodiments of the present application. Arrows 14A1, 14A2, 14A3, and 14A4 shown in fig. 14A and 14B indicate the path of fluid (e.g., air) flowing into the cartridge 10 from the exterior of the cartridge 10 when the user inhales gas from the opening 11 g. Referring to fig. 14A, when a user inhales gas from the opening 11g, arrows 14A1 indicate that external air flows from the fluid passage 17gc, the opening 17g2, and the opening 17g1 into the space below the heating element 16 and between the opening 17g1 and the opening 15g2 (i.e., the atomizing chamber). In the atomizing chamber, the heated and atomized tobacco tar is mixed with air. Arrows 14a1 indicate the flow of mixed gas through opening 15g2 to opening 15g1 and opening 14g 3.

Referring to fig. 14B, arrow 14a2 indicates the mixed gas flowing from opening 15g1 to opening 14g 3. Arrow 14a3 indicates that the mixed gas flows from opening 14g3 to opening 14g2 via fluid passage 14 gc. Referring to fig. 14A, arrow 14A4 indicates that the mixed gas flows from opening 14g2 to opening 14g1, fluid passage 11gc and opening 11g, and is inhaled by the user through opening 11 g. The wicking assembly 12 is disposed in the fluid passage 11gc to prevent the mixed gas from being condensed and leaked by the soot in the storage compartment 11ca while flowing through the fluid passage 11 gc.

Fig. 15A, 15B, 15C are schematic views of gas channels according to some embodiments of the present application. Referring to fig. 15A, the arrow 15A1 indicates the path of outside air entering the cartridge 10. Arrows 15a1 indicate that outside air enters the cartridge from fluid passage 17gc and opening 17g2 and flows from opening 17g1 to opening 15g2, opening 15g1 and opening 14g 3. Referring to fig. 15C, arrows 15a2 indicate that a portion of the gas flows from opening 14g3 to fluid passageway 14vp and to gas vent 14v 1. The fluid passage 14vp may be serrated to prevent oil from leaking out. In some embodiments, the fluid channel 14vp may also be a straight line. Referring to fig. 15A, arrows 15A3 indicate that a portion of the gas flows from opening 14g3 to fluid passageway 14vp, to gas vent 14v1 and to storage compartment 11 ca. When the tobacco tar is atomized and inhaled by the user, the pressure of the storage compartment 11ca may become small and the tobacco tar may not easily flow to the recess 16 ca. The gas paths indicated by the arrows 15A1, 15A2, and 15A3 in fig. 15A and 15C balance the pressure in the storage compartment 11ca and the outside so that the tobacco tar can smoothly flow to the recess 16 ca.

Referring to fig. 15B, the arrow 15a4 indicates the path of outside air entering the cartridge 10. Arrows 15a4 indicate that outside air enters the cartridge from fluid passage 17gc and opening 17g2 and flows from opening 17g1 to opening 15g2, opening 15g1 and opening 14g 3. Referring to fig. 15C, arrows 15a5 indicate that a portion of the gas flows from opening 14g3 along the slit between carrier 14 and housing 11 (not shown in fig. 15C) and toward gas vent 14v 2. Referring to fig. 15B, arrows 15a6 indicate that a portion of the gas flows from opening 14g3 along the slit between carrier 14 and housing 11 (not shown in fig. 15C), to gas vent 14v2 and to storage compartment 11ca via the slit between seal assembly 13 and carrier 14.

As the user continues to use the atomizing device, the tobacco tar in the storage compartment 11ca is continuously consumed and reduced, so that the pressure in the storage compartment 11ca gradually decreases. A negative pressure may be generated when the pressure in the storage compartment 11ca becomes small. The reduced pressure in the storage compartment 11ca may make it difficult for the soot to flow into the recess 16ca of the heating element 16. When the heating element 16 does not completely adsorb the tobacco tar, the heating element 16 at a high temperature may dry out and develop a scorched smell. The gas paths indicated by the arrows 15a4, 15a5, and 15a6 in fig. 15B and 15C balance the pressure in the storage chamber 11ca and the outside so that the tobacco tar can smoothly flow to the recess 16 ca.

seal members

13, 331, 332, 351, 352, 353 and 354 and any one of the

brackets

14 and 34 is 0.1N/cm²(Newton/mm square) to 20N/cm²Within the range of (1). Since any one of the

seal members

13, 331, 332, 351, 352, 353 and 354 and any one of the

brackets

14 and 34 can be integrally formed by injection molding, there are no assembly deviation and tolerance problems, and the risk of liquid leakage (e.g., soot leakage) can be improved.

The seal assembly 451 or the seal assembly 454 and the bracket 14 may be formed by integral injection molding. The bonding force between the seal assembly 451 or the seal assembly 454 and the bracket 14 is 0.1N/cm²(Newton/mm square) to 20N/cm²Within the range of (1). Because the seal assembly 451 or the seal assembly 454 and the bracket 14 can be formed by integral injection molding, assembly deviation and part tolerance problems do not exist, and the risk of liquid leakage (such as smoke oil leakage) can be improved.

Any one of the seal member 452, the seal member 453, and the seal member 455 and the bracket 34 may be formed by integral injection molding. The bonding force between any one of the sealing

members

452, 453 and 455 and the bracket 34 is 0.1N/cm²(Newton/mm square) to 20N/cm²Within the range of (1). Because any one of the

seal members

452, 453, and 455 and the bracket 34 can be integrally formed by injection molding, assembly misalignment and part tolerance problems are eliminated, and the risk of liquid leakage (e.g., soot leakage) is reduced.
