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

One end of the trench 11t1 of the sensor package 11 includes grooves 11c1 and 11c2. The other end of the trench 11t1 of the sensor package 11 includes grooves 11c3 and 11c4. One end of the air intake passage 11a3 of the sensor package 11 is located in the trench 11t1 and adjacent to the groove 11c3. A section of the air intake passage 11a4 of the sensor package 11 is located in the trench 11t1 and adjacent to the groove 11c4. The trench 11t1 of the sensor package 11 includes a groove 11c5. One end of the air intake passage 11a1 is located in the groove 11c5. One end of the air intake passage 11a2 is located in the groove 11c5.

The deviation of the air inlet passage 11a1 from the center line L of the trench 11t1 can avoid interference with the gas flow of the air inlet passage 11a5 (defined by the trench 11t1 and the bottom cover 12 of the power supply assembly). One end of the intake passage 11a2 deviates from the center line L of the trench 11t1 to avoid interference with the gas flow in the intake passage 11a5. The deviation of the air inlet passage 11a3 from the center line L of the trench 11t1 allows the airflow entering from the groove 11c3 to be more efficiently guided into the air inlet passage 11a3. The deviation of the air inlet passage 11a4 from the center line L of the trench 11t1 allows the airflow entering from the groove 11c4 to be more efficiently guided into the air inlet passage 11a4.

The recess 11s3 of the sensor package 11 is connected to one end of the air intake passage 11a3. The recess 11s1 of the sensor package 11 is connected to one end of the air intake passage 11a4. The shape of the intake passage 11a3 may be the same as that of the intake passage 11a4. The shape of the intake passage 11a3 may be different from that of the intake passage 11a4. The intake passage 11a3 or the intake passage 11a4 may have a straight cylindrical shape. The intake passage 11a3 or the intake passage 11a4 may have a tapered 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 (for example, 2, 3...) may be arranged. The recess 11s3 of the sensor package 11 allows a relatively large space between the sensor package 11 and the power supply assembly 9 to prevent the battery assembly 9 from expanding during use and causing gas blockage. The intake passage 11a3 may be substantially parallel to the intake passage 11a4.

The recess 11s1 of the sensor package 11 is connected to one end of the air intake passage 11a1. The recess 11s1 of the sensor package 11 is connected to one end of the air intake passage 11a2. The shape of the intake passage 11a1 may be the same as that of the intake passage 11a2. The shape of the intake passage 11a1 may be different from that of the intake passage 11a2. The intake passage 11a1 or the intake passage 11a2 may have a straight cylindrical shape. The intake passage 11a1 or the intake passage 11a2 may have a tapered 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 (for example, 2, 3...) may be arranged. The intake passage 11a1 may be substantially parallel to the intake passage 11a2.

As shown in FIG. 6A, the solid line represents the sensor package 11, and the dashed line represents the bottom cover 12 of the power supply assembly.

In some embodiments, the air intake passage 11a3 of the sensor package 11 deviates from the center line L of the trench 11t1 so that the gas entering from the hole 12h3 of the power assembly base 12 flows into the air intake passage 11a3 more efficiently. The air intake passage 11a4 of the sensor package 11 deviates from the center line L of the trench 11t1 so that the gas entering from the hole 12h4 of the power assembly base 12 flows into the air intake passage 11a4 more efficiently.

In some embodiments, the projected area of the trench 11t1 of the sensor package 11 partially overlaps with the projected area of the hole 12h5 of the base 12 of the power supply assembly. The projected area of the trench 11t1 of the sensor package 11 encloses the projected area of the hole 12h5 of the power assembly base 12.

In some embodiments, the projected area (projected area) of the air intake channel 11a1 of the sensor package 11 and the projected area of the hole 12h5 of the power assembly base 12 do not overlap (overlap). 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 assembly base 12. The projected area of the air intake channel 11a2 of the sensor package 11 and the projected area of the hole 12h5 of the power supply assembly base 12 do not overlap. 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 assembly base 12.

There is a spatial offset between the projected area of the air intake passage 11a1 and the projected area of the hole 12h5, so that relatively little gas can flow into the air intake passage 11a1 of the sensor package 11 to reach the recess 11s1. The air intake passage 11a2 and the hole 12h5 are spatially offset so that relatively little gas can flow through the air intake passage 11a2 of the sensor package 11 to reach the recess 11s1. The intake passage 11a1 deviates from the center line L of the trench 11t1 so that relatively little gas can flow through the intake passage 11a2 of the sensor package 11 to reach the recess 11s1. The intake passage 11a2 deviates from the center line L of the trench 11t1 so that relatively little gas can flow through the intake passage 11a4 of the sensor package 11 and reach the recess 11s1.

The projected area of the present invention refers to any component (for example, the air inlet passage 11a1 or the hole 12h5) on a plane perpendicular to the longitudinal axis of the atomization device (that is, the virtual axis extending from the through hole 1h1 to the hole 12h5) ( For example, the area projected parallel to the straight line on the surface 12s of the base 12 of the power supply unit. The linear parallel projection in the present invention refers to a linear projection parallel to the longitudinal axis of the atomization device.

The intake passage 11a1 of the sensor package 11 extends along the axis y1. The center of the intake passage 11a1 of the sensor package 11 is located on the axis y1. The hole 12h5 of the power supply unit base 12 extends along the axis y2. The center of the hole 12h5 of the power supply assembly base 12 is located on the axis y2. The axis y1 and the axis y2 may be spaced apart from each other. The axis y1 and the axis y2 may not intersect. There is a distance d1 between the axis y1 and the axis y2, where the distance d1 is greater than zero. The air intake passage 11a1 of the sensor package 11 and the hole 12h5 of the power supply assembly base 12 are non-coaxial.

The intake passage 11a2 of the sensor package 11 extends along the axis y3. The center of the intake passage 11a2 of the sensor package 11 is located on the axis y3. The axis y3 and the axis y2 may be spaced apart from each other. The axis y3 and the axis y2 may not intersect. There is a distance d2 between the axis y3 and the axis y2, where the distance d2 is greater than zero. The air intake passage 11a2 of the sensor package 11 and the hole 12h5 of the power supply assembly base 12 are non-coaxial.

Fig. 6C illustrates a cross-sectional view of the atomizing device along the secant line 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 11a5. The intake passage 11a1 (or 11a2) of the sensor package 11 is arranged in a direction perpendicular to the intake passage 11a5. 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 11a5. The intake passage 11a3 (or 11a4) and the intake passage 11a5 may be substantially perpendicular.

The arrow in Fig. 6C indicates the gas flow direction. The airflow enters the air inlet passage 11a5 from the holes 12h1, 12h2, 12h3, 12h4 or 12h5 of the bottom cover 12 of the power supply assembly.

Referring to FIG. 6C, in some embodiments, a relatively small amount of airflow P2 enters the chamber 50 from the intake passage 11a1 (or the intake passage 11a2).

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

In some embodiments, the airflow P3 and the airflow P2 may be isolated from each other. In some embodiments, the airflow P2 may be mixed with the airflow P3. The gas flow P3 has a relatively large gas flow rate to provide enough gas to heat and atomize the smoke oil. 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, and the recess 11 s3 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 cavity 50.

Referring to FIG. 6D, the sensor 10 can sense different parameters of the reference chamber 40 and the chamber 50, such as air flow, air pressure difference, or sound 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 can detect a relatively small air pressure S2. The sensor 10 can obtain the air pressure difference between the air pressure S1 and the air pressure S2. When the parameter value reaches or exceeds a certain threshold, the atomization device 100 can switch on the circuit between the battery assembly 9 and the heating assembly 6 according to the 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, 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 to stop the battery assembly 9 from supplying power to the heating assembly 6.

The relatively small amount of gas entering the chamber 50 can increase the sensitivity of the sensor 10. The relatively small amount of gas entering the chamber 50 allows the sensor 10 to use low flow measurement to improve the accuracy of the measurement range. The relatively small amount of gas entering the chamber 50 can prevent the user from accidentally touching and generating unintended aerosol.

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 smaller than the width w2 of the intake passage 11a3. The intake passage 11a1 has a relatively small width w1 (that is, represents a small cross-sectional area). Since the width w1 of the intake passage 11a1 is smaller than the width w2 of the intake passage 11a3, the airflow P2 generated by the user's inhalation has a relatively faster flow rate than the airflow P3. The airflow P2 with a faster flow rate can enter the recess 11s1 before the airflow P3 reaches the heating assembly 6 so that the sensor 10 can determine the parameter value of the airflow P2 earlier and connect the circuit between the battery assembly 9 and the heating assembly 6 earlier. The airflow P2 with a faster flow rate can prevent the generation of aerosol from being delayed. The intake passage 11a1 with a smaller width can prevent the generation of aerosol from being delayed. The difference in width between the intake passage 11a1 and the intake passage 11a3 can prevent the generation of aerosol from being delayed. The difference in width between the intake passage 11a1 and the intake passage 11a3 can improve user experience.
