The present invention generally relates to an electronic device, and in particular, to a vaporization device for providing inhalable aerosol.
An electronic cigarette is an electronic product that heats a volatile solution and vaporizes the solution to generate aerosol for a user to inhale. In recent years, major manufacturers begin to produce various electronic cigarette products. Generally, an electronic 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 volatile solution, and the heating component is configured to heat and vaporize the volatile 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 required 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.
The existing electronic cigarette products have different defects. For example, for the electronic cigarette products in the prior art, in order to reduce the number of components, poor component yield may be caused. For the electronic cigarette products in the prior art, in order to reduce the number of components, the costs of manufacturing the component may be increased. In addition, without considering the high temperature problem of the aerosol, the electronic cigarette products in the prior art may cause the potential crisis of user burns.
In addition, an existing electronic cigarette product does not control power output of a heating component. When a user inhales for a long time, a power supply device continuously heats the heating component. The heating component may overheat and generate a scorching smell, which results in bad experience for the user. The overheated heating component may also cause an internal member of the electronic cigarette to be tarnished or even burned. Existing electronic cigarette products without control on power output generally consume power energy quickly.
Therefore, the present disclosure proposes a vaporization device that can resolve the foregoing problem.
A vaporization device is proposed. The vaporization device includes: a heating component; a first conductive component configured to be electrically connected to the heating component; a second conductive component configured to be electrically connected to the heating component; a power supply component configured to output a power to the heating component; an output detecting circuit configured to provide a first detection signal associated with a first resistance value between the first conductive component and the second conductive component; and a controller electrically connected to the output detecting circuit and the power supply component, where when determining that the first detection signal meets a first condition, the controller controls the power supply component to stop outputting the power to the heating component.

The seal member 3 may reduce the difficulty of manufacturing the cartridge housing 2 and the heating component top cap 4. The seal member 3 may prevent the cartridge housing 2 and the heating component top cap 4 from being damaged during the assembling. The seal member 3 may also prevent the e-liquid in the storage compartment 30 from being extracted from the hole 1h.
The tube 4t2 of the heating component top cap 4 may have an inner diameter less than that of the tube 4t1. The tube 4t2 of the heating component top cap 4 may have an outer diameter less than that of the tube 4t1. The tube 4t2 of the heating component top cap 4 extends into the vaporization chamber 40.

Referring to
The airflow 100f generates a temperature change between the heating component 5 and the tube 4t2. Aerosol generated by the heating component 5 generates a temperature change before reaching the tube 4t2.
The non-uniform width of the inner wall of the vaporization chamber 40 may strengthen the temperature change of the airflow 100f. The non-uniform width of the inner wall of the vaporization chamber 40 may accelerate the temperature change of the airflow 100f. The temperature drops when the airflow 100f flows from the width 4L1 to 4L2. Compared with the vaporization chamber with the uniform inner wall width, when the airflow 100f flows from the width 4L1 to 4L2, the temperature decreases more greatly and drops faster. The width of the inner wall of the vaporization chamber 40 is adjusted to control the temperature of the aerosol inhaled by the user from the hole 1h. In some embodiments, the vaporization chamber 40 may also have substantially the same inner wall width.
After entering the vaporization chamber 40 through the hole 7h1, the airflow 100f is heated by the heating component 5 to generate a temperature rise Tr. In some embodiments, the temperature rise Tr may be in a range from 200° C. to 220° C. In some embodiments, the temperature rise Tr may be in a range from 240° C. to 260° C. In some embodiments, the temperature rise Tr may be in a range from 260° C. to 280° C. In some embodiments, the temperature rise Tr may be in a range from 280° C. to 300° C. In some embodiments, the temperature rise Tr may be in a range from 300° C. to 320° C. In some embodiments, the temperature rise Tr may be in a range from 200° C. to 320° C.
The airflow flowing out of the vaporization chamber 40 may generate a temperature drop Tf before reaching the hole 1h. In some embodiments, the temperature drop Tf may be in a range of 145° to 165°. In some embodiments, the temperature drop Tf may be in a range of 165° to 185°. In some embodiments, the temperature drop Tf may be in a range of 205° to 225°. In some embodiments, the temperature drop Tf may be in a range of 225° to 245°. In some embodiments, the temperature drop Tf may be in a range of 245° to 265°. In some embodiments, the temperature drop Tf may be in a range of 145° to 265°.
The airflow channel 100t may have a non-uniform inner diameter. The inner diameter of the airflow channel 100t gradually increases toward the hole 1h from a position close to the heating module 5. A relatively large inner diameter close to the hole 1h may make a volume of the aerosol become larger.
The width of the inner wall of the vaporization chamber 40 and the width of the inner diameter of the airflow channel 100t are adjusted to control the temperature of the aerosol inhaled by the user from the hole 1h. The width of the inner wall of the vaporization chamber 40 and the width of the inner diameter of the airflow channel 100t are adjusted to control the volume of the aerosol inhaled by the user from the hole 1h.

In some embodiments, the aerosol inhaled by the user via the through hole 1h may have a temperature below 65° C. In some embodiments, the aerosol inhaled by the user via the through hole 1h may have a temperature below 55° C. In some embodiments, the aerosol inhaled by the user via the through hole 1h may have a temperature below 50° C.

In some embodiments, that the load impedance of the load system exceeds the normal operating impedance range may be a short circuit in the load system.
When the impedance of the load system (such as the heating component 5) is abnormal, the load system may be abnormally heated, and therefore the load system may overheat, causing harm to a user. Alternatively, the load system may fail to be heated normally to increase the temperature, and therefore e-liquid fails to generate aerosol in the vaporization chamber 40, resulting in incomplete combustion and endangering the user. Enabling the load abnormality protection mode can prevent the power supply component from outputting a power to a load system that exceeds a normal impedance range, thereby effectively reducing a probability of causing harm to a user.

In some embodiments, the light-emitting warning signal is a pulse signal. In some embodiments, the light-emitting warning signal may be a pulse signal with a frequency of 2 Hz. In some embodiments, the red-light-emitting diode 155-D3 of the light-emitting component 155 emits red light. In some embodiments, the red-light-emitting diode 155-D3 emits red blinking light.
In some embodiments, the threshold TN10 may be in a range of 2.0V to 3.0V. In some embodiments, the threshold TN10 may be 2.5V.
Overvoltage Protection and Undervoltage Protection During Charging
The vaporization device may detect an external signal VIN. If the external signal exceeds a normal range, an overvoltage protection mode or an undervoltage protection mode is enabled to prevent the power supply component 20 from being damaged as a result of an excessively high or low external signal VIN.
In some embodiments, the overvoltage protection mode and the undervoltage protection mode may be performed by a combination of the controller 151, the charge detecting circuit 154, and the light-emitting component 155.
In some embodiments, the charging component 18 receives the external signal VIN, and supplies the VIN to the pin 154-1 of the charge detecting circuit 154 through the flat cable 16. The charge detecting circuit 154 supplies a charge detection signal CHARG-DET to the pin 151-2 of the controller 151 through the pin 154-2. The controller 151 determines, based on the charge detection signal CHARG-DET, whether the external signal VIN exceeds a threshold TN11. If the external signal VIN exceeds the threshold TN11, the controller 151 does not supply the charging enable signal CHG_EN to the charge protecting circuit 156 to skip charging the power supply component 20.
In some embodiments, the charging component 18 receives the external signal VIN. The charge detecting circuit 154 receives the external signal VIN to provide a charge detection signal CHARG-DET to the controller 151. If the external signal VIN exceeds the threshold TN11, the pin 151-13 of the controller 151 supplies a light emitting signal L6 to the light-emitting component 155, and light emitted by the light-emitting component 155 is visible through the light-transmissive component 221. In some embodiments, the light emitting signal L6 has intensity changing over time, so that the light-emitting component 155 emits light with intensity changing over time. In some embodiments, the light-emitting warning signal is a pulse signal. In some embodiments, the light emitting signal L6 may be a pulse signal with a frequency of 2 Hz. In some embodiments, the light-emitting diode 155-D4 of the light-emitting component 155 emits white light. In some embodiments, the light-emitting diode 155-D4 emits white blinking light. In some embodiments, the light-emitting diode 155-D4 emits white blinking light six times.
In some embodiments, the threshold TN11 may be in a range of 5.5 V to 6.5 V. In some embodiments, the threshold TN11 may be 5.7 V.
In some embodiments, the charging component 18 receives the external signal VIN. The charge detecting circuit 154 receives the external signal VIN to provide a charge detection signal CHARG-DET to the controller 151. The controller 151 determines, based on the charge detection signal CHARG-DET, whether the external signal VIN is lower than a threshold TN12. If the external signal VIN is lower than the threshold TN12, the controller 151 does not supply the charging enable signal CHG_EN to the charge protecting circuit 156 to skip charging the power supply component 20.
In some embodiments, the charging component 18 receives the external signal VIN. The charge detecting circuit 154 receives the external signal VIN to provide a charge detection signal CHARG-DET to the controller 151. If the external signal VIN exceeds the threshold TN12, the pin 151-13 of the controller 151 supplies a light emitting signal L6 to the light-emitting component 155, and light emitted by the light-emitting component 155 is visible through the light-transmissive component 221. In some embodiments, the light emitting signal L6 has intensity changing over time, so that the light-emitting component 155 emits light with intensity changing over time. In some embodiments, the light-emitting warning signal is a pulse signal. In some embodiments, the light emitting signal L6 may be a pulse signal with a frequency of 2 Hz. In some embodiments, the light-emitting diode 155-D4 of the light-emitting component 155 emits white light. In some embodiments, the light-emitting diode 155-D4 emits white blinking light. In some embodiments, the light-emitting diode 155-D4 emits white blinking light three times.
In some embodiments, the threshold TN12 may be in a range of 3.5 V to 5 V. In some embodiments, the threshold TN12 may be 4.2 V.
Overcharge Protection
The vaporization device may detect the voltage and the charging time of the power supply component 20 during the charging, so as to prevent the power supply component 20 from being damaged due to overcharging of the power supply component 20.
In some embodiments, the controller 151, the charge protecting circuit 156, the charge management circuit 157, and the light-emitting component 155 may be used in combination.
In some embodiments, when the charge management circuit 157 is charging the power supply component 20, the charge management circuit 157 supplies a charging status signal CHG-S TAT to the controller 151, and the controller 151 determines, based on the charging status signal CHG-STAT, whether the voltage of the power supply component 20 exceeds a threshold TN13. In some embodiments, if the voltage of the power supply component 20 exceeds the threshold value TN13, the controller stops providing the charging enable signal CHG_EN to the charge protecting circuit 156. The charge protecting circuit 15 stops providing the charging signal VCC_CHG to the charge management circuit 157. The charge management circuit 157 stops charging the power supply component 20.
In some embodiments, if the voltage of the power supply component 20 exceeds the threshold value TN13, the controller 151 does not supply the charging enable signal CHG_EN to the charge protecting circuit 156 to skip charging the power supply component 20.
In some embodiments, if the voltage of the power supply component 20 exceeds the threshold TN13, the controller 151 stops providing the light emitting signal L5 to the light-emitting component 155 in the previous embodiment so that the light-emitting component 155 stops emitting light.
In some embodiments, the threshold TN13 may be in a range of 4.3 V to 4.4 V. In some embodiments, the threshold TN13 may be 4.35V.
In some embodiments, when the charge management circuit 157 is charging the power supply component 20, the controller enables a timer to count a charging time. When the charging time exceeds a threshold TN14, the controller stops providing the charging enable signal CHG_EN to the charge protecting circuit 156. The charge protecting circuit 15 stops providing the charging signal VCC_CHG to the charge management circuit 157. The charge management circuit 157 stops charging the power supply component 20.
In some embodiments, when the charging time exceeds the threshold TN14, the controller 151 does not supply the charging enable signal CHG_EN to the charge protecting circuit 156 to skip charging the power supply component 20.
In some embodiments, if the voltage of the power supply component 20 exceeds the threshold TN12, the controller 151 stops providing the light emitting signal L5 to the light-emitting component 155 in the previous embodiment so that the light-emitting component 155 stops emitting light.
In some embodiments, the threshold TN14 may be in a range of 2.5 hours to 3.5 hours. In some embodiments, the threshold TN14 may be 3 hours.
As used herein, the terms “approximately,” “substantially,” “substantial” and “about” are used to describe and account for small variations. When used in conjunction with an event or circumstance, the terms can refer to instances in which the event or circumstance occurs precisely as well as instances in which the event or circumstance occurs to a close approximation. 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 expressed herein as being 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 (μm) positioned along a same plane, for example, within 10 μm, 5 μm, 1 μm, or 0.5 μm positioned along a 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,” “substantially,” “substantial,” and “about” are used to describe and explain small variations. When used in conjunction with an event or circumstance, the terms can refer to instances in which the event or circumstance occurs precisely as well as instances in which the event or circumstance occurs to a close approximation. For example, when used in conjunction with a numerical value, the terms can refer to a range of variation less than or equal to ±10% of that numerical value, such as 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 of the values (for example, less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than 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%), the two values may be considered to be “substantially” or “about” 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, if a displacement between two surfaces is equal to or less than 5 μm, equal to or less than 2 μm, equal to or less than 1 μm, or equal to or less than 0.5 μm, the two surfaces may be considered to be coplanar or substantially coplanar. If a displacement between any two points on a surface relative to a plane is equal to or less than 5 μm, equal to or less than 2 μm, equal to or less than 1 μm, or equal to or less than 0.5 μm, the surface may be considered to be flat or substantially flat.
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, components provided “on” or “above” another component may encompass a case in which a previous 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 previous component and the latter component.
As used herein, for ease of description, 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 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 in the present application, terms “approximately”, “basically”, “substantially”, and “about” are used for describing and explaining a small variation. When being used in combination with an event or circumstance, the term may refer to a case in which the event or circumstance occurs precisely, and a case in which the event or circumstance 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 (μm) 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.
