Description

Atomization device

Technical Field

The present invention relates generally to electronic devices, and more particularly to a nebulizing device (aerosol) for providing an inhalable 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 the nebulizable solution, and the heating component is used for heating and nebulizing the nebulizable solution and generating 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.

The existing electronic cigarette products have different defects. For example, the prior art electronic cigarette products may have poor assembly yield due to the reduced number of components. Prior art electronic cigarette products may instead increase component manufacturing costs in order to reduce the number of components. Furthermore, prior art electronic cigarette products may not account for the high temperature of the aerosol, creating a potential risk of user burns.

Furthermore, electronic vapor devices often have some limitations on their repeated use including: the need to replace or fill their soot, complex handling, soot spillage, charring, battery life shortages, and high price, among others, inevitably results in a poor user experience.

Accordingly, the present disclosure provides an atomizing device that can solve the above-mentioned problems.

The gas enters the inlet passage 11a3 (or inlet passage 11a4) (not shown) and flows through the space between the battery pack 9 and the power module housing 13 into the hole 8h1 in the base 8 of the oil storage module. The airflow P1 enters the cavity 4v2 of the heating assembly top cover 4 to contact with the heating assembly 6, and the tobacco tar adsorbed on the heating assembly 6 is heated by the heating circuit 61 to generate aerosol P1' in the cavity 4v 2. As shown in FIG. 3B, aerosol P1' is shown flowing from cavity 4v2 of heating assembly lid 4, around oil guide assembly 5 and center plate 4B1, to cavity 4v1 of heating assembly lid 4. Aerosol P1' flows from cavity 4v1 through cannula 1t1 to aperture 1h1 for inhalation by the user. In some embodiments, cavity 4v1 is in gaseous communication with cavity 4v 2.

After the air flow P1 enters the cavity 4v2 from the hole 8h1, it is heated by the heating element 6 to generate a temperature rise Tr.

In certain embodiments, the temperature drop Tf may be in the range of 165 ℃ to 185 ℃. In certain embodiments, the temperature drop Tf may be in the range of 205 ℃ to 225 ℃. In certain embodiments, the temperature drop Tf may be in the range of 225 ℃ to 245 ℃. In certain embodiments, the temperature drop Tf may be in the range of 245 ℃ to 265 ℃. In certain embodiments, the temperature drop Tf may be in the range of 145 ℃ to 265 ℃.

The cannula 1t1 may have a non-uniform inner diameter. The inner diameter of the pipe 1t1 becomes gradually larger from the position near the heating block 6 toward the hole 1h 1. The larger inner diameter near the hole 1h1 makes the aerosol larger in volume.

By adjusting the width of the cavity 4v1, the inner wall of the cavity 4v2 and the inner diameter of the cannula 1t1, the temperature of the aerosol drawn from the hole 1h1 by the user can be controlled. By adjusting the width of the cavity 4v1, the inner wall of the cavity 4v2 and the inner diameter of the cannula 1t1, the volume of aerosol drawn from the hole 1h1 by the user can be controlled.

The temperature of the aerosol can be controlled to avoid the user from being scalded by the aerosol. Controlling the aerosol volume can enhance the inhalation experience for the user.

In certain embodiments, the aerosol inhaled by the user via the through-hole 1h1 may have a temperature below 65 ℃. In certain embodiments, the aerosol inhaled by the user via the through-hole 1h1 may have a temperature below 55 ℃.

FIG. 4 illustrates a bottom view of a sensor package 11 according to some embodiments of the invention.

One end of the trench 11t1 of the sensor package 11 includes grooves 11c1 and 11c 2. The other end of the trench 11t1 of the sensor package 11 includes grooves 11c3 and 11c 4. One end of the intake passage 11a3 of the sensor package 11 is located in the trench 11t1 and adjacent to the groove 11c 3. A section of the intake passage 11a4 of the sensor package 11 is located in the trench 11t1 and adjacent to the groove 11c 4. The trench 11t1 of the sensor package 11 includes a groove 11c 5. One end of the intake passage 11a1 is located in the groove 11c 5. One end of the intake passage 11a2 is located in the groove 11c 5.

The offset of inlet passage 11a1 from the centerline L of channel 11t1 avoids interference with the flow of air through inlet passage 11a5 (defined by channel 11t1 and power module bottom cover 12). The deviation of one end of the inlet passage 11a2 from the center line L of the trench 11t1 prevents the interference with the gas flow of the inlet passage 11a 5. The offset of the inlet passage 11a3 from the centerline L of the trench 11t1 allows the gas flow entering from the groove 11c3 to be more efficiently directed into the inlet passage 11a 3. The offset of the inlet passage 11a4 from the centerline L of the trench 11t1 allows the gas flow entering from the groove 11c4 to be more efficiently directed into the inlet passage 11a 4.

The recess 11s3 of the sensor package 11 is connected to one end of the intake passage 11a 3. The recess 11s1 of the sensor package 11 is connected to one end of the intake passage 11a 4. The shape of the intake passage 11a3 may be the same as that of the intake passage 11a 4. The shape of the intake passage 11a3 may be different from that of the intake passage 11a 4. The intake passage 11a3 or the intake passage 11a4 may be a straight cylinder. The intake passage 11a3 or the intake passage 11a4 may be tapered in shape. In some embodiments, only one intake passage 11a3 may be provided. In some embodiments, only one intake passage 11a4 may be provided. In some embodiments, multiple intake passages (e.g., 2, 3 …) may be provided. The recess 11s3 of the sensor package 11 allows a relatively large space between the sensor package 11 and the power module 9 to avoid the battery module 9 from expanding during use to cause gas blockage. The intake channel 11a3 may be substantially parallel with the intake channel 11a 4.

The recess 11s1 of the sensor package 11 is connected to one end of the intake passage 11a 1. The recess 11s1 of the sensor package 11 is connected to one end of the intake passage 11a 2. The shape of the intake passage 11a1 may be the same as that of the intake passage 11a 2. The shape of the intake passage 11a1 may be different from that of the intake passage 11a 2. The intake passage 11a1 or the intake passage 11a2 may be a straight cylinder. The intake passage 11a1 or the intake passage 11a2 may be tapered in shape. In some embodiments, only one intake passage 11a1 may be provided. In some embodiments, only one intake passage 11a2 may be provided. In some embodiments, multiple intake passages (e.g., 2, 3 …) may be provided. The intake channel 11a1 may be substantially parallel with the intake channel 11a 2.

As shown in fig. 6A, the solid line indicates the sensor package 11, and the broken line indicates the power supply component bottom cover 12.

In some embodiments, the offset of inlet channel 11a3 of sensor package 11 from the centerline L of channel 11t1 allows gas entering through aperture 12h3 of power supply base 12 to flow more efficiently into inlet channel 11a 3. The offset of the inlet channel 11a4 of the sensor package 11 from the center line L of the channel 11t1 allows the gas entering from the hole 12h4 of the power supply assembly base 12 to flow into the inlet channel 11a4 more efficiently.

In some embodiments, the projected area of the trench 11t1 of the sensor package 11 partially coincides with the projected area of the aperture 12h5 of the power module base 12. The projected area of the trench 11t1 of the sensor package 11 surrounds the projected area of the hole 12h5 of the power module base 12.

In some embodiments, the projected area (projected area) of the intake passage 11a1 of the sensor package 11 is not coincident (overlap) with the projected area of the aperture 12h5 of the power module base 12. The projected area of the air intake passage 11a1 of the sensor package 11 is offset from the projected area of the hole 12h5 of the power supply unit base 12. The projected area of the intake passage 11a2 of the sensor package 11 does not coincide with the projected area of the hole 12h5 of the power module base 12. The projected area of the air intake passage 11a2 of the sensor package 11 is offset from the projected area of the hole 12h5 of the power supply unit base 12.

The offset in space between the projected area of the inlet passage 11a1 and the projected area of the hole 12h5 allows relatively less gas to flow into the inlet passage 11a1 of the sensor package 11 to reach the recess 11s 1. The offset in space of the inlet passage 11a2 from the hole 12h5 allows relatively little gas to flow through the inlet passage 11a2 of the sensor package 11 to the recess 11s 1. The offset of the inlet passage 11a1 from the centerline L of the trench 11t1 allows relatively little gas to flow through the inlet passage 11a2 of the sensor package 11 to the recess 11s 1. The offset of the inlet passage 11a2 from the centerline L of the trench 11t1 allows relatively little gas to flow through the inlet passage 11a4 of the sensor package 11 to the recess 11s 1.

The projected area of the present invention refers to the area projected straight in parallel on a plane (e.g., the surface 12s of the power module base 12) perpendicular to the longitudinal axis of the atomizer (i.e., the virtual axis extending from the through hole 1h1 to the hole 12h5) of any module (e.g., the intake passage 11a1 or the hole 12h 5). The straight-line parallel projection of the present invention refers to a straight-line projection parallel to the longitudinal axis of the atomizing device.

The intake passage 11a1 of the sensor package 11 extends along the axis y 1. The center of the intake passage 11a1 of the sensor package 11 is located on the axis y 1. The hole 12h5 of the power module base 12 extends along the axis y 2. The hole 12h5 of the power module base 12 is centered on the axis y 2. The axis y1 and the axis y2 may be spaced apart (spaced apart from each other). Axis y1 and axis y2 may not intersect. There is a distance d1 between axis y1 and axis y2, wherein distance d1 is greater than zero. The intake passage 11a1 of the sensor package 11 is not coaxial with the hole 12h5 of the power module base 12.

The intake passage 11a2 of the sensor package 11 extends along the axis y 3. The center of the intake passage 11a2 of the sensor package 11 is located on the axis y 3. The axis y3 and the axis y2 may be spaced apart (spaced apart from each other). Axis y3 and axis y2 may not intersect. There is a distance d2 between axis y3 and axis y2, wherein distance d2 is greater than zero. The intake passage 11a2 of the sensor package 11 is not coaxial with the hole 12h5 of the power module base 12.

Fig. 6C illustrates a cross-sectional view of the atomizing device along secant E-E of fig. 6A.

In some embodiments, the intake passage 11a1 (or the intake passage 11a2) of the sensor package 11 communicates with the intake passage 11a 5. The intake passage 11a1 (or 11a2) of the sensor package 11 is disposed in a perpendicular direction with respect to the intake passage 11a 5. The intake passage 11a1 (or 11a2) and the intake passage 11a5 may be substantially perpendicular. In some embodiments, the intake passage 11a3 (or 11a4) of the sensor package 11 communicates with the intake passage 11a 5. The intake passage 11a3 (or 11a4) and the intake passage 11a5 may be substantially perpendicular.

The arrows in fig. 6C indicate the gas flow direction. The air flows from the holes 12h1, 12h2, 12h3, 12h4 or 12h5 of the power supply bottom cover 12 into the air intake passage 11a 5.

Referring to FIG. 6C, in some embodiments, relatively little air flow P2 enters chamber 50 from intake passage 11a1 (or intake passage 11a 2).

In some embodiments, the air flow P3 enters the hole 8h1 of the oil storage pack base 8 from the air inlet passage 11a3 (or air inlet passage 11a4) through the gap between the battery pack 9 and the power pack housing 13. The space between the battery pack 9 and the power pack housing 13 is in fluid communication with the oil reservoir assembly 100A. The space between the battery pack 9 and the power pack housing 13 is in fluid communication with the hole 8h1 of the oil reservoir pack base 8. The airflow P3 contacts with the heating element 6, and the tobacco tar adsorbed on the heating element 6 is heated to generate aerosol. The aerosol flows through the cannula 1t1 to the hole 1h1 for the user to inhale.

In certain embodiments, the airflow P3 may be isolated from the airflow P2. In certain embodiments, the airflow P2 may mix with the airflow P3. The gas flow P3 has a relatively large gas flow rate to provide enough gas to heat and atomize the tobacco tar. The gas flow P2 has a relatively small gas flow rate, which increases the sensitivity of the sensor 10.

The bottom of the battery assembly 9, the top of the sensor 10, the recess 11s3 of the sensor package 11 define a reference chamber 40. The bottom 10 of the sensor and the bottom of the sensor package 11 define a chamber 50.

Referring to fig. 6D, sensor 10 may sense various parameters of reference chamber 40 and chamber 50, such as gas flow, air pressure differential, or acoustic waves. The chamber 40 has a relatively large volume. When the airflow P2 enters the chamber 40, the bottom of the sensor 10 can detect a relatively large air pressure S1. The chamber 50 has a relatively small volume. When the airflow P2 enters the chamber 50, the top of the sensor 10 detects a relatively small air pressure S2. The sensor 10 may obtain a pressure differential between the air pressure S1 and the air pressure S2. When the parameter value reaches or exceeds a certain threshold value, the atomization device 100 can switch on a circuit between the battery assembly 9 and the heating assembly 6 according to a signal provided by the sensor 10, so that the battery assembly 9 supplies power to the heating assembly 6. When the pressure difference is lower than or reaches a certain threshold value, the atomization device 100 can disconnect the circuit between the battery assembly 9 and the heating assembly 6 according to the signal provided by the sensor 10, so as to stop the power supply of the battery assembly 9 to the heating assembly 6.

Relatively less gas entering the chamber 50 may increase the sensitivity of the sensor 10. Relatively less gas entering the chamber 50 may allow the sensor 10 to employ low flow measurements to improve the accuracy of the measurement range. Relatively less gas enters the chamber 50 to prevent accidental contact by the user and the generation of an unintended aerosol.

Referring to fig. 6D, the intake passage 11a1 has a width w1, the intake passage 11a3 has a width w2, and the width w1 of the intake passage 11a1 may be less than the width w2 of the intake passage 11a 3. The intake passage 11a1 has a relatively small width w1 (i.e., representing a small cross-sectional area). Since the width w1 of the air inlet passage 11a1 is smaller than the width w2 of the air inlet passage 11a3, the air flow P2 generated by the inhalation of the user has a relatively fast flow rate compared with the air flow P3. The faster flow rate of the air P2 may enter the recess 11s1 before the air P3 reaches the heater module 6, allowing the sensor 10 to determine the value of the parameter of the air P2 earlier and to make an early electrical connection between the battery module 9 and the heater module 6. The faster flow rate of the air stream P2 prevents delay in the generation of the aerosol. The small width of the intake passage 11a1 prevents delay in generation of the aerosol. The difference in width between the intake passage 11a1 and the intake passage 11a3 prevents the generation of mist from being delayed. The difference in the width of the intake passage 11a1 and the intake passage 11a3 may enhance the user experience.
