VAPORIZATION DEVICE

CROSS REFERENCE TO RELATED APPLICATIONS

The present application claims the benefit of priority from the China Patent Application No. 201911136490.7, filed on 19 Nov. 2019, the disclosure of which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION
1. Field of the Invention

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

2. Description of the Related Art

An e-cigarette is an electronic product that heats a vaporizable solution and vaporizes the solution to generate aerosol for a user to inhale. In recent years, major manufacturers begin to produce various e-cigarette products. Generally, an e-cigarette product includes a housing, an e-liquid storage chamber, a vaporization chamber, a heating component, an air inlet, an airflow channel, an air outlet, a power supply device, a sensing device, and a control device. The e-liquid storage chamber is configured to store a vaporizable solution, and the heating component is configured to heat the vaporizable solution and vaporize the solution to generate aerosol. The air inlet is in communication with the vaporization chamber, and air is supplied to the heating component when a user inhales. The aerosol generated by the heating component is first generated in the vaporization chamber, then flows through the airflow channel and the air outlet, and is finally inhaled by the user. The power supply device supplies power needed by the heating component, and the control device controls a heating time of the heating component based on an inhalation action of the user detected by the sensing device. The housing wraps each of the foregoing components.

Existing e-cigarette products may use a sensor to detect the inhalation action of the user. To detect the airflow, the sensor has a portion that is in communication with the airflow channel. The vaporizable solution or condensed liquid may infiltrate a portion of which the sensor is in communication with the airflow channel during use, causing the sensor to malfunction or fail.

In addition, pressure balance of the e-liquid storage chamber is not taken into account for the existing e-cigarette product. In the existing e-cigarette product, the e-liquid storage chamber is generally designed to be completely sealed to prevent the vaporizable solution from leaking. As users continue to use e-cigarette products, the vaporizable solution in the e-liquid storage chamber is continuously consumed and reduced, causing a decrease in the pressure and form a negative pressure in the e-liquid storage chamber. The negative pressure causes the vaporizable solution in the e-liquid storage chamber to be difficult to flow uniformly to the heating component, and the heating component does not uniformly adsorb the vaporizable solution. In this case, when the temperature of the heating component rises, there will be a high probability of dry boiling and scorching, thus resulting in a poor user experience.

Therefore, a vaporization device that can resolve the foregoing problem is provided.

FIG. 3D and FIG. 3E are three-dimensional views of a heating component top cap according to some embodiments of the present disclosure.

FIG. 3F is a three-dimensional view of a channel in a heating component top cap according to some embodiments of the present disclosure.

Referring to FIG. 3D to FIG. 3F, a heating component top cap 5 may have a channel 5v. The channel 5v may include a first portion 5v1 and a second portion 5v2. The first portion 5v1 and the second portion 5v2 are in fluid communication with each other. In some embodiments, the channel 5v may include more portions that are in communication with each other. As shown in FIG. 3C, the first portion 5v1 extends in a direction of an axis 5x1, and the second portion 5v2 extends in a direction of an axis 5x2. The axis 5x1 is substantially perpendicular to the surface 5s1. The axis 5x2 is substantially perpendicular to the surface 5s1. The axis 5x1 and the axis 5x2 do not overlap each other. The opening 5h4 and the opening 5h5 do not overlap in a direction perpendicular to the surface 5s1.

The first portion 5v1 extends into the heating component top cap 5 from the opening 5h4 on the surface 5s1. The first portion 5v1 extends toward a surface 5s2 by a distance h2 from the surface 5s1. The distance h2 is less than a distance h1 between the surface 5s1 and the surface 5s2. The first portion 5v1 has a bottom surface 5s3 inside the heating component top cap 5, and the bottom surface 5s3 has a diameter d3.

In some embodiments, the diameter d1 is different from the diameter d3. In some embodiments, the diameter d1 is less than the diameter d3. In some embodiments, the diameter d1 may be identical to the diameter d3. In some embodiments, an inner diameter of the first portion 5v1 gradually increases in a direction from the surface 5s1 to the bottom surface 5s3. In some embodiments, an inner diameter of the first portion 5v1 monotonically increases in a direction from the surface 5s1 to the bottom surface 5s3. In some embodiments, an inner wall of the first portion 5v1 includes a smooth surface.

In some embodiments, the second portion 5v2 may have a uniform inner diameter. In some embodiments, the inner diameter of the second portion 5v2 is identical to a diameter of the opening 5h5. In some embodiments, the inner diameter of the second portion 5v2 may be different from the diameter of the opening 5h5.

Referring to FIG. 3F, there is a distance h3 between a joint of the second portion 5v2 and the first portion 5v1 and the bottom surface 5s3. In some embodiments, the distance h3 is not zero. In some embodiments, a ratio of the distance h3 to the distance h2 is in a range of 0.1 to 0.5. In some embodiments, a ratio of the distance h3 to the distance h2 is in a range of 0.5 to 0.9.

The heating component top cap 5 has the opening 5h5 on the surface 5s2. Airflow may reach the opening 5h4 on the surface 5s1 from the opening 5h5 through the second portion 5v2 and the first portion 5v1.

FIG. 4A and FIG. 4B are sectional views of a cartridge according to some embodiments of the present disclosure.

As shown in FIG. 4A, a mouthpiece 1 has an opening 1h. A cartridge housing 3 has a tube 3t extending toward a top cap sealing component 4 from the opening 1h. The tube 3t, the top cap sealing component 4, and the cartridge housing 3 define a liquid storage tank 20. Vaporizable materials may be stored in the liquid storage tank 20.

The tube 3t may have a portion extending into a channel 5c1. The tube 3t may have a non-uniform outer diameter. As shown in FIG. 4A, the portion that is of the tube 3t and that extends into the channel 5c1 has a relatively small outer diameter. The tube 3t may have a non-uniform inner diameter. As shown in FIG. 4A, the portion that is of the tube 3t and that extends into the channel 5c1 has a relatively small inner diameter.

The tube 3t is coupled to the channel 5c1 via an opening 5h1 of a heating component top cap 5. The tube 3t is in fluid communication with the channel 5c1 via the opening 5h1 of the heating component top cap 5. The channel 5c1 is isolated from the liquid storage tank 20 via the tube 3t.

As shown in FIG. 4A, the top cap sealing component 4 may expose openings 5h1, 5h2, and 5h3 of the heating component top cap 5. The top cap sealing component 4 does not cover the openings 5h1, 5h2, and 5h3 of the heating component top cap 5. The top cap sealing component 4 does not block channels 5c1, 5c2, and 5c3.

The channel 5c2 is in fluid communication with a groove 7c of a heating component 7. The channel 5c3 is in fluid communication with the groove 7c of the heating component 7. E-liquid stored in the liquid storage tank 20 may flow into the groove 7c through the channel 5c2. The e-liquid stored in the liquid storage tank 20 may flow into the groove 7c through the channel 5c3. The groove 7c of the heating component 7 is in fluid communication with the liquid storage tank 20. The e-liquid may be in full contact with the heating component 7 in the groove 7c. A heating circuit on a surface of or inside the heating component 7 may heat the e-liquid and generate aerosol.

A vaporization chamber 8C is defined between a heating component base 8 and the heating component 7. The heating component 7 is partially exposed to the vaporization chamber 8C. The aerosol generated through heating by the heating component 7 is formed in the vaporization chamber 8C. The aerosol generated through heating by the heating component 7 is sucked by a user via the tube 3t and the opening 1h. The tube 3t is in fluid communication with the vaporization chamber 8C. A groove 5r1 (refer to FIG. 3A) is in fluid communication with the vaporization chamber 6C.

The top cap sealing component 4 may cover an opening 5h4 of the heating component top cap 5. The top cap sealing component 4 may block a channel 5v.

As shown in FIG. 4A, the heating component top cap 5 has a blocking member 5p. The blocking member 5p isolates the tube 3t from the groove 7c of the heating component 7. The blocking member 5p isolates the channel 5c1 from the groove 7c of the heating component 7.

During use of a vaporization device, when a condensed liquid remaining in the tube 3t reaches a specific volume, the condensed liquid may slip from the tube 3t. The blocking member 5p may prevent the condensed liquid slipping from the tube 3t from being in contact with the heating component 7. The blocking member 5p may prevent the heating component 7 from being contaminated by the slipped condensed liquid. The blocking member 5p may prevent the slipped condensed liquid from changing a taste of the aerosol. The blocking member 5p may prevent liquid from splashing due to the condensed liquid slipping to a high-temperature heating component. The blocking member 5p may prevent the splashed liquid from scalding the user.

FIG. 4A shows airflow 8f from the vaporization chamber 8C to the liquid storage tank 20.

When the vaporization device is idle and not sucked by the user, the opening 5h4 is closely engaged with the top cap sealing component 4, and the e-liquid in the liquid storage tank 20 does not leak from the channel 5v.

As the user continues to use the vaporization device, a vaporizable solution in the liquid storage tank 20 is continuously consumed and reduced, so that a pressure in the liquid storage tank 20 gradually decreases. A decrease in the pressure in the liquid storage tank 20 may generate a negative pressure. The decrease in the pressure in the liquid storage tank 20 may make it difficult for a volatile solution to flow through the channels 5c1 and 5c2 to the groove 7c of the heating component 7. When the groove 7c does not completely adsorb the volatile solution, the high-temperature heating component 7 may boil dry and generate scorched flavor.

The foregoing problem may be alleviated through the channel 5v disposed in the heating component top cap 5. The channel 5v disposed in the heating component top cap 5 is in fluid communication with the vaporization chamber 8C, which may balance the pressure in the liquid storage tank 20.

Because the vaporization chamber 8C is in fluid communication with the tube 3t, a pressure in the vaporization chamber 8C is approximately equal to an atmospheric pressure. When the vaporizable solution in the liquid storage tank 20 is continuously reduced, the pressure in the liquid storage tank 20 is gradually less than the atmospheric pressure. A pressure difference between the vaporization chamber 8C and the liquid storage tank 20 causes the airflow 8f to reach a junction of the opening 5h4 and the top cap sealing component 4 through the channel 5v from the vaporization chamber 8C. The airflow 8f may partially push away the top cap sealing component 4. The airflow 8f may cause partial deformation of the top cap sealing component 4. The airflow 8f may enter the liquid storage tank 20 through a gap generated by the deformation of the top cap sealing component 4. The airflow 8f entering the liquid storage tank 20 may increase the pressure in the liquid storage tank 20. The airflow 8f entering the liquid storage tank 20 may balance a pressure between the liquid storage tank 20 and the vaporization chamber 8C.

In some embodiments, the heating component top cap 5 may be additionally provided with a channel having a same function as the channel 5v. For example, the heating component top cap 5 may also be provided with a ventilation channel close to the opening 5h3.

As shown in FIG. 3A, the channel 5v has an exterior with a narrow top and a wide bottom. The exterior of the channel 5v has many advantages. The channel 5v with a narrow top and a wide bottom may accelerate an airflow change. A speed at which the airflow 8f leaves a narrow opening (5h4) of the channel 5v is faster than a speed at which the airflow enters a wide opening (5h5) of the channel 5v. The accelerated airflow 8f may better push open the top cap sealing component 4 and increase efficiency of balancing the pressure between the liquid storage tank 20 and the vaporization chamber 8C.

FIG. 4B is a sectional view of a cartridge according to another embodiment of the present disclosure.

The heating component top cap 5 includes the channel 5v composed of a first portion 5v1 and a second portion 5v2 (refer to FIG. 3F). Because a joint between the second portion 5v2 and the first portion 5v1 and a bottom surface 5s3 are spaced apart by a distance h3, a groove for storing liquid is formed at a bottom of the first portion 5v1. In the process of pushing open the top cap sealing component 4 by the airflow 8f, if a small amount of e-liquid leaks into the channel 5v along a gap 201 from the opening 5h4, the groove at the bottom of the first portion 5v1 may store the leaked e-liquid, thereby reducing a probability that an electronic component is damaged due to the e-liquid flowing into a body 100B.

Similarly, the first portion 5v1 of the channel 5v also has an exterior with a narrow top and a wide bottom. The exterior of the first portion 5v1 may increase efficiency of balancing the pressure between the liquid storage tank 20 and the vaporization chamber 8C.

FIG. 5A and FIG. 5B are exploded views of a body of a vaporization device according to some embodiments of the present disclosure.

A body 100B includes a sensor bracket 9, a connecting member 10, a sensor 11, a circuit board 12, a flat cable 13, a vibrator 14, a charging component 15, a circuit board bracket 16, a buffer component 17, a power supply component 18, a sealing component 19, a frame component 20, a conductive pin 21, a magnetic component 22, a power supply component bracket 23, and a body housing 24.

The sensor bracket 9 may be disposed in a groove 23r3 of the power supply component bracket 23. A groove 9r is disposed on one side of the sensor bracket 9. The sensor 11 may be disposed in the groove 9r. An opening 9h is disposed on the other side of the sensor bracket 9. The opening 9h is in fluid communication with an opening 10h1 of the connecting member 10 (refer to FIG. 7B). The opening 9h is in fluid communication with an opening 23h1 of the power supply component bracket 23 (refer to FIG. 6 and FIG. 7B).

FIG. 6 is a three-dimensional view of a sensor top cap and a power supply component bracket according to some embodiments of the present disclosure.

As shown in FIG. 6, an opening 10h1 of a connecting member 10 penetrates through the connecting member 10 in a direction of an axis 10x. The connecting member 10 has an extending portion 10p and an annular portion 10b.

The extending portion 10p has flexibility. The annular portion 10b has flexibility. When the connecting member 10 is assembled to a power supply component bracket 23, the extending portion 10p and the annular portion 10b pass through an opening 23h2 on the power supply component bracket 23. The annular portion 10b has a larger diameter than the opening 23h2. When the annular portion 10b passes through the opening 23h2, the connecting member 10 and the power supply component bracket 23 may be fixed to each other. The connecting member 10 may be fixed onto the power supply component bracket 23 via the annular portion 10b.

The power supply component bracket 23 includes an opening 23h1 and a groove 23r2. The opening 23h1 is adjacent to the groove 23r2. The opening 23h1 penetrates through the power supply component bracket 23 along a direction of an axis 23x.

When the connecting member 10 is assembled to the power supply component bracket 23, the opening 23h1 and the opening 10h1 do not overlap in a vertical direction. When the connecting member 10 is assembled to the power supply component bracket 23, the axis 10x and the axis 23x do not overlap. When the connecting member 10 is assembled to the power supply component bracket 23, the axis 10x extends through the groove 23r2. When the connecting member 10 is assembled to the power supply component bracket 23, the opening 10h1 extends through the groove 23r2.

The groove 23r2 may temporarily store e-liquid leaking from a cartridge 100A, and the groove 23r2 may temporarily store condensed liquid leaking from the cartridge 100A. The groove 23r2 may reduce contact of the e-liquid or the condensed liquid with an electronic component in a body 100B. The groove 23r2 may reduce a failure of the electronic component in the body 100B due to the e-liquid or the condensed liquid.

FIG. 7A is a sectional view of a body of a vaporization device according to some embodiments of the present disclosure.

A body 100B has a receiving portion 24r that may be used to receive a portion of a cartridge 100A. When the cartridge 100A and the body 100B are engaged with each other, a conductive pin 21 may be in contact with metal pads 8m1 and 8m2 at the bottom of the cartridge 100A, thereby supplying power to a heating component 7.

When the cartridge 100A is engaged with the body 100B, airflow 11f is generated in the body 100B when a user inhales via an opening 1h. The airflow 11f leaves a connecting member 10 through an opening 10h1 of the connecting member 10. The airflow 11f enters the receiving portion 24r of the body 100B through the opening 10h1 of the connecting member 10. The airflow 11f may be detected by a sensor 11, and then a controller 121 is enabled to supply a current to the heating component 7.

FIG. 7B is a sectional view of a body of a vaporization device according to some embodiments of the present disclosure.

As shown in FIG. 7B, a power supply component bracket 23 has a groove 23r2 close to a connecting member 10. If e-liquid or condensed liquid in a cartridge 100A leaks into a body 100B along an opening 10h1, the groove 23r2 may temporarily receive the liquid to prevent the liquid from being in direct contact with a sensor 11 or other electronic components.

A sensor bracket 9 has a groove 9r1. An extending direction of an opening of the groove 9r1 is the same as an extending direction of the opening 10h1. The extending direction of the opening of the groove 9r1 is the same as an extending direction of an opening 23h1. The opening 23h1 of the power supply component bracket 23 extends through the groove 9r1.

If the e-liquid or the condensed liquid in the cartridge 100A leaks into the body 100B along the opening 10h1, the groove 9r1 may temporarily receive the liquid to prevent the liquid from being in contact with the sensor 11 via an opening 9h of the sensor bracket 9. If the e-liquid or the condensed liquid in the cartridge 100A leaks into the body 100B along the opening 10h1, the groove 9r1 may temporarily receive the liquid to prevent the liquid from being in contact with other electronic components in the body 100B.

The sensor bracket 9 and the power supply component bracket 23 together define a trench 9r2. An opening of the trench 9r2 faces a direction of the opening 10h1. The trench 9r2 extends along a direction of an axis 9x. The axis 9x and an axis 23x (refer to FIG. 6) do not overlap. The axis 9x and an axis 10x (refer to FIG. 6) do not overlap.

If the e-liquid or the condensed liquid in the cartridge 100A leaks into the body 100B along the opening 10h1, the trench 9r2 may temporarily receive the liquid to prevent the liquid from being in contact with the sensor 11 via the opening 9h of the sensor bracket 9. If the e-liquid or the condensed liquid in the cartridge 100A leaks into the body 100B along the opening 10h1, the trench 9r2 may temporarily receive the liquid to prevent the liquid from being in contact with other electronic components in the body 100B.

In some embodiments, a bottom surface of the groove 23r2 and a bottom surface of the groove 9r1 may be on a same plane. In some embodiments, the bottom surface of the groove 23r2 and the bottom surface of the groove 9r1 are not on the same plane. In some embodiments, the bottom surface of the groove 23r2 and the bottom surface of the groove 9r1 are spaced apart by a distance 9d1.

In some embodiments, the bottom surface of the groove 9r1 and a bottom surface of the trench 9r2 may be on a same plane. In some embodiments, the bottom surface of the groove 9r1 and the bottom surface of the trench 9r2 are not on the same plane. In some embodiments, the bottom surface of the groove 9r1 and the bottom surface of the trench 9r2 are spaced apart by a distance 9d2.

The bottom surface of the groove 23r2 and the bottom surface of the trench 9r2 are spaced apart by a distance (9d1+9d2).

The non-coplanarity of the bottom surface of the groove 23r2 and the bottom surface of the groove 9r1 may bring many advantages. The non-coplanarity of the bottom surface of the groove 9r1 and the bottom surface of the trench 9r2 may bring many advantages.

The bottom surface of the groove 23r2 and the bottom surface of the groove 9r1 are not coplanar, so that the e-liquid or the condensed liquid entering the body 100B via the opening 10h1 needs to change a direction several times to reach the opening 9h. The bottom surface of the groove 23r2 and the bottom surface of the groove 9r1 are not coplanar, so that a failure probability of the sensor 11 can be reduced.

The bottom surface of the groove 9r1 and the bottom surface of the trench 9r2 are not coplanar, so that the e-liquid or the condensed liquid entering the body 100B via the opening 10h1 needs to change a direction several times to reach the opening 9h. The bottom surface of the groove 9r1 and the bottom surface of the trench 9r2 are not coplanar, so that a failure probability of the sensor 11 can be reduced.

As used herein, space-related terms such as “under”, “below”, “lower portion”, “above”, “upper portion”, “lower portion”, “left side”, “right side”, and the like may be used herein to simply describe a relationship between one component or feature and another component or feature as shown in the figures. In addition to orientation shown in the figures, space-related terms are intended to encompass different orientations of the device in use or operation. An apparatus may be oriented in other ways (rotated 90 degrees or at other orientations), and the space-related descriptors used herein may also be used for explanation accordingly. It should be understood that when a component is “connected” or “coupled” to another component, the component may be directly connected to or coupled to another component, or an intermediate component may exist.

As used herein, the terms “approximately”, “basically”, “substantially”, and “about” are used to describe and explain small variations. When used in combination with an event or a situation, the terms may refer to an example in which an event or a situation occurs accurately and an example in which the event or situation occurs approximately. For example, when being used in combination with a value, the term may refer to a variation range of less than or equal to ±10% of the value, for example, less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. For example, if a difference between two values is less than or equal to ±10% of an average value of the value (for example, less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%), it could be considered that the two values are “substantially” the same. For example, being “substantially” parallel may refer to an angular variation range of less than or equal to ±10° with respect to 0°, for example, less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°. For example, being “substantially” perpendicular may refer to an angular variation range of less than or equal to ±10° with respect to 90°, for example, less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°. less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°.

For example, two surfaces can be deemed to be coplanar or substantially coplanar if a displacement between the two surfaces is no greater than 5 μm, no greater than 2 μm, no greater than 1 μm, or no greater than 0.5 μm. A surface can be deemed to be planar or substantially planar if a difference between any two points on the surface is no greater than 5 μm, no greater than 2 μm, no greater than 1 μm, or no greater than 0.5 μm.

As used herein, the terms “conductive”, “electrically conductive”, and “electrical conductivity” refer to an ability to transport an electric current. Electrically conductive materials typically indicate those materials that exhibit little or no opposition to the flow of an electric current. One measure of electrical conductivity is Siemens per meter (S/m). Typically, an electrically conductive material is one having a conductivity greater than approximately 10⁴S/m, such as at least 10⁵S/m or at least 10⁶S/m. The electrical conductivity of a material can sometimes vary with temperature. Unless otherwise specified, the electrical conductivity of a material is measured at room temperature.

As used herein, the singular terms “a/an” and “the” may include plural referents unless the context clearly dictates otherwise. In the description of some embodiments, components provided “on” or “above” another component may encompass a case in which a former component is directly on a latter component (for example, in physical contact with the latter component), and a case in which one or more intermediate components are located between the former component and the latter component.

Unless otherwise specified, spatial descriptions such as “above”, “below”, “upper”, “left”, “right”, “lower”, “top”, “bottom”, “vertical”, “horizontal”, “side”, “higher”, “lower”, “upper portion”, “on”, “under”, and “downward” are indicated relative to the orientations shown in the figures. It should be understood that the space descriptions used herein are merely for illustrative purposes, and actual implementations of the structures described herein may be spatially arranged in any orientation or manner, provided that the advantages of embodiments of the present disclosure are not deviated due to such arrangement.
