The present application claims the benefit of priority from the China Patent Application No. 201910697664.0, filed on 30 Jul. 2019, the disclosure of which is hereby incorporated by reference in its entirety.
The present application generally relates to a vaporization device, and more particularly to an electronic device for providing an inhalable aerosol.
An electronic cigarette is an electronic product that heats and vaporizes a vaporizable solution to produce an aerosol for a user to inhale. In recent years, major manufacturers begin to produce various electronic cigarette products. Existing electronic cigarette products have different defects, which may be generated by improper design of relative positions between different members. For example, in a common electronic cigarette product, a heating component, an airflow channel, and an air outlet are designed to be aligned with each other in a vertical direction. Because the airflow channel has a certain length, the aerosol passing through the airflow channel may be cooled to form a condensate attached to the wall of the airflow channel. For this design, when the residual condensate reaches a particular volume, the condensate easily falls down from the airflow channel to contact with the heating component. The fallen condensate may contaminate the heating component and change the flavor of the aerosol. In addition, when the condensate directly falls onto the heating component with high temperature, the liquid may be splashed, and the splashed liquid may even burn the user.
Therefore, a vaporization device which can resolve the above problem is provided.
A vaporization device is provided. The vaporization device includes a housing, a heating component cap having a first surface and a second surface, and a first sealing member disposed on the heating component cap. The first surface has an edge, a length extending along a first axis, and a width extending along a second axis. The heating component cap includes a first groove, and the first groove and the first sealing member define a first channel. The first sealing member covers the first groove on the first surface, and exposes the first groove on the second surface.
A vaporization device is provided. The vaporization device includes a housing, a heating component cap, a heating component base, a first sealing member disposed on the heating component cap, and a heating component disposed between the heating component cap and the heating component base. The heating component and the heating component base define an atomization chamber. The heating component cap includes a first opening on a first surface and a first groove at an edge, and the first sealing member covers the first opening and exposes the first opening.

The tube 1t is coupled to the channel 3c3 through the opening 3h3 of the cap heating component 3. The tube 1t is in fluid communication with the channel 3c3 through the opening 3h3 of the cap heating component 3. The channel 3c3 is isolated from the liquid storage compartment 20 through the tube 1t.
As shown in
The channel 3c1 is in fluid communication with the groove 5c of the heating component 5. The channel 3c2 is in fluid communication with the groove 5c of the heating component 5. The e-liquid stored in the liquid storage compartment 20 may flow into the groove 5c through the channel 3c1.

During the process of using the vaporization device, when the residual condensate in the tube 1t reaches a particular volume, the condensate may fall from the tube 1t. The blocking element 3p can prevent the condensate falling from the tube 1t from coming into contact with the heating component 5. The blocking element 3p can prevent the fallen condensate from contaminating the heating component 5. The blocking element 3p can prevent the fallen condensate from changing the flavor of the aerosol. The blocking element 3p can prevent the condensate from falling onto the heating component with high temperature to cause splashing of the liquid. The blocking element 3p can prevent the splashed liquid from burning the user.
The existing electronic cigarette products fail to take the pressure balance of the e-liquid storage chamber into consideration. In the existing electronic cigarette products, the e-liquid storage chamber is generally designed to be completely sealed to prevent spilling of the vaporizable solution. As the user continuously uses the electronic cigarette product, the amount of the vaporizable solution in the e-liquid storage chamber continuously decreases, so that the pressure in the e-liquid storage chamber decreases to form a negative pressure. The negative pressure makes it difficult for the vaporizable solution in the e-liquid storage chamber to evenly flow to the heating component, and the heating component cannot evenly absorb the vaporizable solution. In this case, when the temperature of the heating component rises, there will be a high probability that no vaporizable solution exists on portion of the heating component during heating and a burning smell may be generated, resulting in poor user experience.
When the atomizing device is placed still and not used by the user, the opening 3h4 is tightly combined with the cap sealing member 2, and the e-liquid in the liquid storage compartment 20 does not leak out from the channel 3c4. When the vaporization device is placed still and not used by the user, the top of the channel 3c5 is tightly combined with the cap sealing member 2, and the e-liquid in the liquid storage compartment 20 does not leak out from the channel 3c5.
As the user continuously uses the vaporization device, the amount of the vaporizable solution in the liquid storage compartment 20 continuously decreases, so that the pressure in the liquid storage compartment 20 gradually decreases. The decrease in the pressure in the liquid storage compartment 20 may lead to the formation of a negative pressure. The decrease in the pressure in the liquid storage compartment 20 makes it difficult for the vaporizable solution to flow to the groove 5c of the heating component 5 through the channels 3c1 and 3c2. When the groove 5c does not completely absorb the vaporizable solution, no vaporizable solution exists on portion of the heating component during heating and a burning smell may be generated.
The foregoing problem can be resolved by the configuration of the channel 3c4 in the heating component cap 3. The foregoing problem can be resolved by the configuration of the channel 3c5 in the heating component cap 3. The configuration of the channel 3c4 in the heating component cap 3 can balance the pressure in the liquid storage compartment 20. The configuration of the channel 3c5 in the heating component cap 3 can balance the pressure in the liquid storage compartment 20. In some embodiments, the heating component cap 3 only has one of the channel 3c4 or the channel 3c5. In some embodiments, the heating component cap 3 may have both the channel 3c4 and the channel 3c5.
Because the atomization chamber 6C is in fluid communication with the tube 1t, the pressure in the atomization chamber 6C is approximately equal to one atmospheric pressure. As the vaporizable solution in the liquid storage compartment 20 continuously decreases, the pressure in the liquid storage compartment 20 gradually decreases to less than one atmospheric pressure.
The pressure difference between the atomization chamber 6C and the liquid storage compartment 20 causes the airflow 6f1 from the atomization chamber 6C to reach a junction of the opening 3h4 and the cap sealing member 2 through the channel 3c4. The airflow 6f1 may partially push open the cap sealing member 2. The airflow 6f1 may partially deform the cap sealing member 2. The airflow 6f1 may enter the liquid storage compartment 20 through a gap generated by the deformation of the cap sealing member 2.
The pressure difference between the atomization chamber 6C and the liquid storage compartment 20 causes the airflow 6f2 from the atomization chamber 6C to reach a junction of the groove 3r2 and the cap sealing member 2 through the channel 3c5. The airflow 6f2 may partially push open the cap sealing member 2. The airflow 6f2 may partially deform the cap sealing member 2. The airflow 6f2 may enter the liquid storage compartment 20 through a gap generated by the deformation of the cap sealing member 2.
The airflow 6f1 entering the liquid storage compartment 20 can increase the pressure in the liquid storage compartment 20. The airflow 6f1 entering the liquid storage compartment 20 can balance the pressure between the liquid storage compartment 20 and the atomization chamber 6C. The airflow 6f2 entering the liquid storage compartment 20 can increase the pressure in the liquid storage compartment 20. The airflow 6f2 entering the liquid storage compartment 20 can balance the pressure between the liquid storage compartment 20 and the atomization chamber 6C.
The groove 3r1 is formed between pillar portions 3w1 and 3w2. The groove 3r1 is formed between the heating component cap 3 and the housing 1. The groove 3r1 creates a space between the heating component cap 3 and the housing 1. The groove 3r1 enables the channel 3c3 of the heating component cap 3 to be in fluid communication with the atomization chamber 6C. The blocking element 3p is disposed between the channels 3c2 and 3c3. The blocking element 3p may prevent the condensate falling from the tube 1t from coming into contact with the heating component 5.
As used herein, spatially relative 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 element or feature and another element or feature as shown in the figures. In addition to orientation shown in the figures, spatially relative 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 spatially relative 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 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. As used herein with respect to a given value or range, the term “about” generally means in the range of ±10%, ±5%, ±1%, or ±0.5% of the given value or range. The range may be indicated herein as from one endpoint to another endpoint or between two endpoints. Unless otherwise specified, all ranges disclosed herein include endpoints. The term “substantially coplanar” may refer to two surfaces within a few micrometers (m) positioned along the same plane, for example, within 10 μm, within 5 μm, within 1 μm, or within 0.5 μm located along the same plane. When reference is made to “substantially” the same numerical value or characteristic, the term may refer to a value within ±10%, ±5%, ±1%, or ±0.5% of the average of the values.
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 104 S/m, such as at least 105 S/m or at least 106 S/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, assemblies provided “on” or “above” another assembly may encompass a case in which a former assembly is directly on a latter assembly (for example, in physical contact with the latter assembly), and a case in which one or more intermediate assemblies are located between the former assembly and the latter assembly.
Unless otherwise specified, space descriptions such as “above”, “below”, “up”, “left”, “right”, “down”, “top portion”, “bottom portion”, “vertical”, “horizontal”, “side face”, “higher than”, “lower than”, “upper portion”, “on”, “under”, “downward”, etc. are indicated relative to the orientation 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 invention are not deviated due to such arrangement.
