Description

Atomizing device

Technical field

The present disclosure generally relates to a vaporization device, and in particular, to an electronic device that provides an aerosol.

Background technique

An electronic cigarette is an electronic product that heats and atomizes an atomizable solution and generates an aerosol for users to inhale. In recent years, major manufacturers have begun to produce all kinds of electronic cigarette products. Generally speaking, an electronic cigarette product includes a casing, an oil storage chamber, an atomization chamber, a heating component, 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 vaporizable solution, and the heating component is used for heating and atomizing the atomizable solution and generating aerosol. The air inlet and the atomizing chamber communicate with each other, and provide air to the heating assembly when the user inhales. The aerosol generated by the heating element is first generated in the atomization chamber, and then inhaled by the user through the air flow channel and the air outlet. The power supply device provides the power required by the heating element, and the control device controls the heating time of the heating element according to the user's inhalation action detected by the sensing device. The shell covers the above-mentioned components.

In the manufacturing process of electronic cigarettes, the e-liquid is usually injected first and then sealed. However, the sealed e-liquid container is likely to cause e-liquid leakage in the subsequent assembly process, which will make the quality of the product difficult to control. In addition, the sealed e-liquid container is also prone to leakage due to temperature changes during transportation, which affects the yield of the product.

When the user uses the electronic cigarette, the generated aerosol may condense in each cavity or channel to form a liquid. For example, the aerosol may condense to form liquid in the cavity or passage such as the atomization chamber, the air inlet, the air flow channel, or the air outlet. The liquid in the cavities or channels may leak during the user's use of the electronic cigarette. In addition, the e-liquid may also leak if it is not properly stored. Such leakage will contaminate the user's clothes, pants or other valuables carried with him, thereby causing a bad user experience.

When the user uses the electronic cigarette, the e-liquid is heated by the heating element to generate aerosol. If the current cannot pass through the heating element, the heating element cannot generate aerosol. In addition, if the e-liquid cannot reach the heating element smoothly, the heating element cannot generate aerosol. Failure to generate aerosol will cause a bad user experience.

As the frequency of use continues to increase, how to reduce the assembly cost of e-cigarettes through various improvements and make e-cigarettes better meet the needs of users so as to improve user experience is an indispensable link in the development of e-cigarettes.

Therefore, an atomization device that can solve the above-mentioned problems is proposed.

The fluid passage 11gc has a gradually larger inner diameter at one end close to the bracket 14. The fluid channel 11gc has a uniform outer diameter. When the sealing assembly 13 is combined with the housing 11, the fluid channel 11gc is inserted into the platform 13m at a wall close to the side of the bracket 14. When the sealing assembly 13 is combined with the housing 11, since the platform 13m is inserted by the wall of the fluid channel 11gc, a groove and interference are generated at the corresponding position of the platform 13m to form a liquid or gas seal. When the amount of interference is 0.15mm to 0.25mm, there is a better sealing effect. When the amount of interference is less than 0.1mm, the e-liquid may leak. The ring structure 13r1 is attached to the outer surface of the tube structure 14t. In some embodiments, the shape of the ring structure 13r1 corresponds to the wall of the fluid channel 11gc with a decreasing thickness. In some embodiments, the shape of the ring structure 13r1 corresponds to the opening of the fluid channel 11gc with a gradually larger diameter. The ring structure 13r1 conforms to the wall of the fluid channel 11gc whose thickness decreases. The ring structure 13r1 conforms to the opening of the fluid channel 11gc with a gradually larger diameter.

At a distance from the opening 11g, the thickness of the outer wall 11w becomes smaller. At a distance of 11g, the inner surface of the outer wall 11w is stepped. When the sealing component 13 is combined with the housing 11, the stepped inner surface of the outer wall 11w abuts the inclined surface 13rs of the sealing component 13. When the sealing assembly 13 is combined with the housing 11, because the stepped inner surface of the outer wall 11w abuts the inclined surface 13rs of the sealing assembly 13, the inclined surface 13rs generates grooves and interference to form a liquid or gas seal. When the amount of interference is 0.15mm to 0.25mm, there is a better sealing effect. When the amount of interference is less than 0.1mm, the e-liquid may leak.

When the sealing assembly 13 is combined with the housing 11, the flange 13f1 of the sealing assembly 13 abuts the inner surface of the outer wall 11. . When the sealing assembly 13 is combined with the housing 11, because the flange 13f1 abuts the inner surface of the outer wall 11, the flange 13f1 is squeezed and interfered to form a liquid or gas seal. When the amount of interference is 0.15mm to 0.25mm, there is a better sealing effect. When the amount of interference is less than 0.1mm, the e-liquid may leak.

When the sealing component 15 is combined with the housing 11, the flange 15f3 of the sealing component 15 abuts the inner surface of the outer wall 11 to form a liquid or gas seal. When the sealing component 15 is combined with the housing 11, the flange 15f3 is pressed against the inner surface of the outer wall 11, and the flange 15f3 is squeezed and interfered to form a liquid or gas seal. When the amount of interference is 0.15mm to 0.25mm, there is a better sealing effect. When the amount of interference is less than 0.1mm, the e-liquid may leak.

In FIGS. 12C and 12D, in the combination of the sealing assembly 13, the bracket 14 and the housing 11, the air hole 14v2 forms a fluid passage between the upper portion 14tp of the bracket 14 and the groove 13gr2. When the e-liquid is atomized and inhaled by the user, the pressure of the storage compartment 11ca may become smaller and the e-liquid may not easily flow to the depression 16ca. Through the slits between the sealing assembly 13 and the bracket 14, and through the slits between the sealing assembly 13, the bracket 14 and the housing 11, the air hole 14v2 can balance the storage compartment 11ca for storing smoke oil (as shown in Figure 12A) The pressure in) is the same as the pressure outside the housing 11.

In FIG. 12D, the seal assembly 15 includes a ring structure 15r. The ring structure 15r is provided in the hole 15h1. The ring structure 15r is arranged on the stepped inner surface of the hole 15h1. The ring structure 15r protrudes from the inner surface of the hole 15h1. The ring structure 15r protrudes downward. The area of the top surface of the ring structure 15r is smaller than the area of the bottom surface thereof. The longitudinal section shape of the ring structure 15r is a trapezoid or 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 the ring structure 15r. 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 squeezes the annular structure 15r and generates an interference amount to form a liquid or gas seal. When the amount of interference is 0.15mm to 0.25mm, there is a better sealing effect. When the amount of interference is less than 0.1mm, the e-liquid may leak.

In FIG. 12D, when the heating assembly 16 is combined with the sealing assembly 13, the bracket 14 and the sealing assembly 15, the hole 15h1 surrounds the heating assembly 16. The heating element 16 abuts the inner surface of the hole 15h1. The hole 15h1 surrounds the flange 16f of the heating element 16. The flange 16f of the heating element 16 abuts the inner surface of the hole 15h1. In some embodiments, the flange 16f of the heating element 16 creates a groove and interference at the corresponding position on the inner surface of the hole 15h1 to form a liquid or gas seal. When the amount of interference is 0.15mm to 0.25mm, there is a better sealing effect. When the amount of interference is less than 0.1mm, the e-liquid may leak.

In FIG. 12D, the opening 14g3, the opening 15g1, and the opening 15g2 are not fluidly connected to the storage compartment 11ca, the hole 13h1, the hole 14h1, and the hole 15h2.

In the process of assembling the cartridge 10, the storage compartment 11ca needs to be filled with e-liquid to be atomized. In some embodiments, the e-liquid may be poured into the storage compartment 11ca in the state shown in FIG. 12C or FIG. 12D. In some embodiments, the e-liquid can be poured 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 shown in Fig. 12C or Fig. 12D; the hole 15h2 on the other side The hole 14h1 and the hole 13h1 can balance the internal and external pressures of the storage compartment 11ca during the e-liquid filling.

12E shows the housing 11, the liquid suction assembly 12, the sealing assembly 13, the bracket 14, the sealing assembly 15, the heating assembly 16, and the base 17. Referring to FIG. 12E, the base 17 is combined with the housing 11, the liquid suction assembly 12, the sealing assembly 13, the bracket 14, the sealing assembly 15 and the heating assembly 16 from bottom to top (as shown in FIG. 12C). The flange 17f1 of the base 17 abuts against the inner surface of the outer wall 11w of the housing 11 to form a liquid or gas seal. Except for the spring 17s, the contact 17c1 and the magnetic component 17m, the base 17 is mostly made of hard plastic, such as polypropylene (PP) or polyethylene (PE), but other suitable materials can be selected according to the actual situation, and it is not limited Here. 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 will be inserted into the hole 15h2 and the hole 14h1. The column structure 17c passes through the hole 15h2 of the sealing assembly 15. The hole 15h2 of the sealing assembly 15 surrounds a portion of the column structure 17c. The post 17c of the base 17 will be inserted into the hole 15h2 so that the hole 13h1 is not in fluid communication with the hole 14h1.

Fig. 12F is a partial enlarged view of Fig. 12E. When the base 17 is combined with the housing 11, the liquid suction assembly 12, the sealing assembly 13, the bracket 14, the sealing assembly 15 and the heating assembly 16 shown in FIG. 12C, the top of the column 17c is approximately at the hole 14h1. The post 17c of the base 17 will be inserted into the hole 15h2 and the hole 14h1. The column structure 17c passes through the hole 15h2 of the sealing assembly 15. The hole 15h2 of the sealing assembly 15 surrounds a portion of the column structure 17c. The post 17c of the base 17 will be inserted into the hole 15h2 so that the hole 13h1 is not in fluid communication with the hole 14h1. Because the post 17c of the base 17 will be inserted into the hole 15h2 and the hole 14h1, the storage compartment 11ca is not in fluid communication with the hole 15h1. The storage compartment 11ca is in fluid communication with the hole 13h2, the hole 14h2, the hole 15h1, and the recess 16ca of the heating assembly 16. The opening 14g2 and the opening 14g1 are not in fluid communication with the storage compartment 11ca.

Fig. 12G is a partial enlarged view of Fig. 12E. The opening 17g2, the fluid channel 17gc and the opening 17g1 are in fluid communication. Through the opening 15g1, the opening 14g3, and the fluid channel 14gc (not shown in FIG. 12G), the opening 14g2 can be in fluid communication with the opening 17g2, the fluid channel 17gc, and the opening 17g1. The magnetic component 17m can be magnetically attached to the corresponding magnetic component (not shown) of the cigarette rod. When the magnetic component 17m is magnetically attached to the corresponding magnetic component of the cigarette rod, the cartridge 10 can be correctly positioned to the cigarette rod. The contact 17c1 can be in contact with a conductive component (not shown) of the cigarette rod. The energy from the battery of the cigarette rod is transferred to the contact 17c1, the spring sheet 17s and the heating assembly 16 through the conductive component contacting the contact 17c1. The contact 17c1 can be formed by the portion 17s1 of the spring leaf 17s.

12G, when the base 17 is combined with the housing 11, the liquid suction assembly 12, the sealing assembly 13, the bracket 14, the sealing assembly 15 and the heating assembly 16 shown in FIG. 12C, the post 17c will create the hole 15h2 of the sealing assembly 15 The inner surface is squeezed and interference is generated to form a liquid or gas seal. When the amount of interference is 0.15mm to 0.25mm, there is a better sealing effect. When the amount of interference is less than 0.1mm, the e-liquid may leak.

After pouring the e-liquid into the storage compartment 11ca in the state of FIG. 12C, the base 17 will be combined with the housing 11, the liquid suction assembly 12, the sealing assembly 13, the bracket 14, the sealing assembly 15 and the heating assembly 16 shown in FIG. 12C. In the state of FIG. 12E, the e-liquid stored in the storage compartment 11ca can no longer flow out through the hole 13h1, the hole 14h1, and the hole 15h2. In the state of FIG. 12E, the e-liquid stored in the storage compartment 11ca can only flow 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 can absorb the e-liquid 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 16ca.

In some embodiments, if the sealing component 25 shown in FIG. 7A is used instead of the sealing component 15 shown in FIG. 12E, the combined cartridge may not include the flange 15f3 shown in FIG. 12G. However, because of the flange 17f1, the flange 13f1, and other flanges, even if there is no flange 15f3, the cartridge 10 still has sealing properties for the stored e-liquid and the inhaled gas.

13A and 13B are cross-sectional views of the cartridge 10 according to some embodiments of the application. The housing 11 can be similar to a flat and long cylindrical body. 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 mouth shape of the user, so that the user can easily hold the nozzle cover 11m. 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 assembly 16 via the hole 13h2, the hole 14h2, and the hole 15h1. The e-liquid stored in the storage compartment 11ca flows to the recess 16ca of the heating element 16 through the holes 13h2, 14h2, and 15h1, so that the heating element 16 absorbs the e-liquid for heating and atomization.

The opening 11g is in fluid communication with the fluid channel 11gc, the liquid suction assembly 12, and the opening 14g1. The opening 17g2 is in fluid communication with the opening 17g1. The opening 17g1 is in fluid communication with the opening 14g1 via the opening 15g2, the opening 15g1, the opening 14g3, the fluid channel 14gc, and the opening 14g2 (not shown in FIG. 13A). When the user inhales from the opening 11g, external air flows from the fluid channel 17gc (not shown in FIG. 13A) and the opening 17g2 to the opening 17g1. After the external air is mixed with the atomized e-liquid at the opening 15g2 (not shown in FIG. 13A), it flows to the opening 15g1, the opening 14g3, the fluid channel 14gc and the opening 14g2 (not shown in FIG. 13A), and then flows to the opening 14g1 and The fluid channel 11gc is finally inhaled by the user at the opening 11g.

Referring to FIG. 13B, the opening 17g1 is in fluid communication with the opening 15g2, the opening 15g1, and the opening 14g3. In some embodiments, the space below the heating element 16 and the opening 17g1 and the opening 15g2 may be referred to as an atomization chamber. In some embodiments, the space below the contact 16c of the heating element 16 and the heating circuit 16hc, and the space between the opening 17g1 and the opening 15g2 can be referred to as an atomization chamber. The gas inhaled from the outside and the atomized e-liquid are mixed in the atomizing chamber. When the user inhales from the opening 11g (not shown in FIG. 13B), external air flows from the fluid channel 17gc (not shown in FIG. 13B) and the opening 17g2 (not shown in FIG. 13B) to the opening 17g1. After the external air is mixed with the atomized e-liquid at the opening 15g2 (or atomization chamber), it flows to the opening 15g1, the opening 14g3, the fluid channel 14gc (not shown in Figure 13B) and the opening 14g2 (not shown in Figure 13B) ), then flows to the opening 14g1 (not shown in FIG. 13B) and the fluid channel 11gc (not shown in FIG. 13B), and finally is inhaled by the user at the opening 11g (not shown in FIG. 13B).

Referring to FIG. 13B, the spring sheet 17s is used to conduct current to the contact point 16c of the heating element 16 to increase the temperature of the heating element 16. The spring piece 17s is formed of a conductive material. The contact 17c1 is in electrical communication with the spring piece 17s. In some embodiments, the contact 17c1 and the spring leaf 17s are formed by a single conductive component. In some embodiments, the contact 17c1 is formed by a part of the spring leaf 17s. The area of the contact 17c1 is defined by the aperture of the hole 17h1. The contact 17c1 can be in contact with a conductive component (not shown) of the cigarette rod. The energy from the battery of the cigarette rod is transferred to the contact 17c1, the spring sheet 17s and the heating assembly 16 through the conductive component contacting the contact 17c1. The energy of the battery is transferred to the contact 16c of the heating assembly 16 and the heating circuit 16hc via the contact 17c1 and the spring sheet 17s, so as to heat and atomize the smoke oil absorbed by the heating assembly 16.

In some embodiments, when the base 17 is combined with the housing 11, the liquid suction assembly 12, the sealing assembly 13, the bracket 14, the sealing assembly 15, and the heating assembly 16 to form the cartridge 10, the height of the spring sheet 17s is compressed. Because the height of the spring sheet 17s is compressed, the spring sheet 17s generates a force applied to the heating element 16 so that the spring sheet 17s closely abuts the contact point 16c of the heating element 16. The spring sheet 17s closely abuts the contact point 16c of the heating element 16 to reduce the chance of poor contact or disconnection between the spring sheet 17s and the heating element 16.

Referring to FIG. 5A, the bracket 14 includes an air hole 14v1 and a fluid channel 14vp. The fluid channel 14vp is in fluid communication with the air hole 14v1 and the fluid channel 14gc. When the e-liquid is atomized and inhaled by the user, the pressure of the storage compartment 11ca may become smaller and the e-liquid may not easily flow to the depression 16ca. Referring to Figure 13B, when the external air flows from the fluid channel 17gc (not shown in Figure 13B) and the opening 17g2 (not shown in Figure 13B) to the opening 17g1, and the external air interacts with the mist at the opening 15g2 (or atomization chamber). When the mixed e-liquid flows to the opening 15g1, the opening 14g3, and the fluid channel 14gc (not shown in Figure 13B), the pressure of the storage compartment 11ca can be connected to the outside via the fluid channel 14vp and the air hole 14v1 in fluid communication with the fluid channel 14gc. Pressure balance.

14A and 14B are schematic diagrams of gas channels in some embodiments of the application. Arrows 14a1, 14a2, 14a3, and 14a4 shown in FIGS. 14A and 14B indicate the path of fluid (such as air) flowing from the outside of the cartridge 10 into the cartridge 10 when the user inhales gas from the opening 11g. 14A, when the user inhales air from the opening 11g, the arrow 14a1 indicates that the outside air flows from the fluid channel 17gc, the opening 17g2, and the opening 17g1 into the underside of the heating element 16 and in the space between the opening 17g1 and the opening 15g2 (ie, the atomization chamber) middle. In the atomization chamber, the heated and atomized e-liquid is mixed with air. The arrow 14a1 indicates that the mixed gas flows through the opening 15g2 to the opening 15g1 and the opening 14g3.

Referring to Fig. 14B, arrow 14a2 indicates that the mixed gas flows from opening 15g1 to opening 14g3. The arrow 14a3 indicates that the mixed gas flows from the opening 14g3 to the opening 14g2 via the fluid channel 14gc. 14A, the arrow 14a4 indicates that the mixed gas flows from the opening 14g2 to the opening 14g1, the fluid channel 11gc, and the opening 11g, and is inhaled by the user through the opening 11g. The liquid suction assembly 12 is arranged in the fluid channel 11gc to prevent the mixed gas from being condensed by the e-liquid in the storage compartment 11ca and leaking when the mixed gas flows through the fluid channel 11gc.

15A, 15B, and 15C are schematic diagrams of gas channels in some embodiments of the application. Referring to FIG. 15A, the arrow 15a1 indicates the path of the external air entering the cartridge 10. The arrow 15a1 indicates that external air enters the cartridge from the fluid channel 17gc and the opening 17g2, and flows from the opening 17g1 to the opening 15g2, the opening 15g1, and the opening 14g3. Referring to FIG. 15C, the arrow 15a2 indicates that part of the gas flows from the opening 14g3 to the fluid channel 14vp and to the air hole 14v1. The fluid channel 14vp can be serrated to prevent the e-liquid from leaking out. In some embodiments, the fluid channel 14vp may also be a straight line. Referring to FIG. 15A, the arrow 15a3 indicates that part of the gas flows from the opening 14g3 to the fluid channel 14vp, to the air hole 14v1, and to the storage compartment 11ca. When the e-liquid is atomized and inhaled by the user, the pressure of the storage compartment 11ca may become smaller and the e-liquid may not easily flow to the depression 16ca. The gas paths indicated by arrows 15a1, 15a2, and 15a3 in FIGS. 15A and 15C can balance the pressure of the storage compartment 11ca and the outside, so that the e-liquid can flow smoothly to the recess 16ca.

Referring to FIG. 15B, the arrow 15a4 indicates the path of the external air entering the cartridge 10. The arrow 15a4 indicates that external air enters the cartridge from the fluid channel 17gc and the opening 17g2, and flows from the opening 17g1 to the opening 15g2, the opening 15g1, and the opening 14g3. Referring to FIG. 15C, the arrow 15a5 indicates that part of the gas flows from the opening 14g3 along the slit between the bracket 14 and the housing 11 (not shown in FIG. 15C), and flows to the air hole 14v2. 15B, the arrow 15a6 indicates that part of the gas flows from the opening 14g3 along the slit between the bracket 14 and the housing 11 (not shown in FIG. 15C), flows to the air hole 14v2, and passes through the slit between the sealing assembly 13 and the bracket 14. Flow to the storage compartment 11ca.

As the user continues to use the atomization device, the e-liquid in the storage compartment 11ca is continuously consumed and reduced, so that the pressure in the storage compartment 11ca gradually decreases. When the pressure in the storage compartment 11ca decreases, negative pressure may be generated. The decrease of the pressure in the storage compartment 11ca may make it difficult for the e-liquid to flow to the recess 16ca of the heating assembly 16. When the heating element 16 does not completely absorb the e-liquid, the high-temperature heating element 16 may burn dry and produce a burnt smell. The gas paths indicated by arrows 15a4, 15a5, and 15a6 in FIGS. 15B and 15C can balance the pressure of the storage compartment 11ca and the outside, so that the e-liquid can flow smoothly to the recess 16ca.
