Continuing to refer to fig. 6, fig. 6 shows a perspective view of the base 12 in one direction. The base 12 includes a bottom wall 121, and a first sidewall 122 and a second sidewall 123 extending axially from the bottom wall 121 toward the nozzle 15, the first sidewall 122 and the second sidewall 123 defining an annular gap 124. The second sidewall 123 and the bottom wall 121 define a mounting chamber 1231 for mounting the ultrasonic atomizing assembly 13, and the sealing seat 14 is disposed on the base 12, and at least a portion of the sealing seat is elastically abutted against the upper end cap of the atomizing plate 131. A first extending portion 125 and a second extending portion 126 axially extend from the bottom portion 121 along the first sidewall 122, the first extending portion 125 is provided with a second through hole 1251 axially penetrating through the body thereof, the second extending portion 126 is provided with a third through hole 1261 axially penetrating through the body thereof, a conductive element 127 is inserted in the second through hole 1251, the conductive element 127 penetrates through the second through hole 1251, a first air inlet pipe 128 is inserted in the third through hole 1261, and a second air inlet pipe 129 is sleeved on the first air inlet pipe 128.

Continuing to refer to fig. 7, fig. 7 shows a perspective view of the conductive element 127 in one direction. Conductive element 127 is formed entirely of a conductive metal material and has a spherical upper end 1271 and an opposite lower end 1272, with the cross-sectional area of lower end 1272 being greater than the cross-sectional area of upper end 1271. When the conductive element 1271 is inserted into the second through hole 1251, the spherical upper end 1271 protrudes from the second through hole 1251 and is exposed to the liquid storage chamber 17. The lower end 1272 is protruded from the second through hole 1251, and the cross-sectional area of the lower end 1272 is larger than that of the second through hole 1251, so that the lower end 1272 is reversely buckled at the opening of the second through hole 1251.

With continued reference to fig. 8, fig. 8 shows a perspective view of the seal retainer 14 in one direction. The end face 141 of the sealing seat 14 is configured as a concave slope, i.e. the base 14 has an open end in the shape of a bell, which opens towards the mouthpiece 15. And the end surface 141 is formed with a fourth through hole 1411 by retraction, and the hole edge of the fourth through hole 1411 is elastically abutted with the upper end cap of the atomizing sheet 131, so that the atomizing sheet 131 can be exposed through the fourth through hole 1411. Thereby allowing a portion of the liquid matrix of the reservoir 17 to be stored in the seal 14, the reservoir 17 being divided into a first portion 171 and a second portion 172, the cross-sectional area of the first portion 171 being greater than the cross-sectional area of the second portion 172, and the atomization sheet 131 being immersed in the liquid matrix of the second portion 172.

It should be noted that the liquid storage cavity 17 is divided into the first portion 171 and the second portion 172, so that when the liquid substrate in the atomizer 10 is excessively consumed, the remaining liquid substrate can flow back into the second portion 172 through the slope of the open end, and since the cross-sectional area of the second portion 172 is smaller than that of the first portion 171, a certain liquid level can be maintained when the remaining liquid substrate flows back into the second portion 172, and when the atomizing plate 131 ultrasonically atomizes the liquid substrate, a certain liquid level needs to be maintained, and the liquid level is too low, which may affect the atomizing effect.

The seal holder 14 is provided with a first avoiding hole 142 for exposing the upper end 1271 of the conductive element 127, and a second avoiding hole 143 for passing the first air inlet pipe 128. The upper end 1271 of the conductive element 127 is exposed to the second portion 172 of the reservoir 17 through the first relief hole 142, and since the first conductive electrode of the ultrasonic atomization assembly 13 is also in contact with the liquid substrate, when the liquid substrate is conductive liquid, current flows through the first conductive electrode after the electronic atomization device 100 is powered, and an electrical signal on the first conductive electrode is transmitted to the conductive element 127 through the conductive liquid substrate, and the conductive element 127 can receive the electrical signal.

Further, the power supply mechanism 20 generally includes a battery cell 21, a connection terminal 22, and a controller (not shown), wherein the battery cell 21 and the connection terminal 22 are electrically connected to the controller, and the conductive element 127 is also electrically connected to the controller. Therefore, based on the above description, when the electronic atomization device 100 is powered on, a current flows through the first conductive electrode in the atomizer 10, and at this time, if the liquid level is higher than the exposed portion of the conductive element 127, an electrical signal of the first conductive electrode can be transmitted to the conductive element 127 through the conductive liquid substrate, the conductive element 127 sends the received electrical signal to the controller, and the controller can judge that the liquid level is suitable at present, the controller controls the electrical core 21 to provide electrical energy to the atomization sheet 131 through the connection terminal 22, and the atomization sheet 131 can perform ultrasonic atomization on the liquid substrate to generate aerosol.

If the liquid level is lower than the exposed portion of the conductive element 127, at this time, the electrical signal of the first conductive electrode cannot be transmitted to the exposed portion 1271 of the conductive element 127, the conductive element 127 does not receive the electrical signal, the controller cannot receive the electrical signal sent by the conductive element 127, at this time, the controller can determine that the liquid level is too low, the atomizing plate 131 is easily burned, and the controller controls to cut off the electrical connection path between the electrical core 21 and the atomizing plate 131.

In addition, since the upper end 1271 of the conductive element 127 is exposed to the second portion 172 of the reservoir 17 and the atomizing plate 131 is also exposed to the second portion 172, the liquid medium in the first portion 171 can be sufficiently utilized.

Further, with continued reference to fig. 7, the conductive element 127 is inserted into a portion of the second through hole 1251, the outer surface of which is provided with a plurality of protruding ribs 1273 protruding in the radial direction, and the protruding ribs 1273 are in interference fit with the inner wall of the second through hole 1251, so as to seal the assembly gap between the conductive element 127 and the second through hole 1251 and prevent the liquid matrix from leaking through the assembly gap between the conductive element 127 and the second through hole 1251. Of course, in other embodiments of the present invention, only one rib 1273 may be disposed on the conductive element 127, and only the assembly gap between the conductive element 127 and the second through hole 1251 needs to be sealed.

In addition, the conductive element 127 is made of conductive metal which is easy to be magnetized, a magnetic member capable of generating a magnetic field is arranged in the power supply mechanism 20, and since the lower end 1272 of the conductive element 127 protrudes out of the second through hole 1251 and is exposed outside the atomizer 10, the atomizer 10 and the power supply mechanism 20 can be connected in a magnetic attraction manner through the conductive element 127, so that the detachable connection is realized. At this time, the conductive element 127 not only realizes the function of magnetic attraction connection, but also realizes the function of liquid level detection. It is easy to understand that in other embodiments of the present invention, the conductive element 127 can be made of a metal material capable of generating a magnetic field and conducting electricity, for example, any one of a neodymium-iron-boron strong magnet, a samarium-cobalt magnet, an alnico magnet, or an iron-chromium-cobalt magnet, and a metal that can be easily magnetized is provided in the power mechanism 20, so that the conductive element 127 can achieve both the magnetic connection and the liquid level detection function.

In this embodiment, the conductive elements 127 include two conductive elements 127, two conductive elements 127 are symmetrically arranged along the axis of the atomizer 10 with respect to the atomizing plate 131, and the heights of the two conductive elements 127 exposed to the reservoir 17 are also consistent, as shown in fig. 9. When a user uses the electronic atomization device 100 to perform suction in an inclined state, the liquid matrix in the atomizer 10 is concentrated on one side, the liquid level of the liquid matrix on the other side is correspondingly reduced, at this time, the liquid level of the side is lower than the exposed part of the corresponding conductive element 127, at this time, the conductive element 127 on the side cannot receive the electric signal sent by the first conductive electrode, the controller determines that the liquid level of the side is too low, and the controller controls to cut off the electric connection path between the electric core 21 and the atomization sheet 131, so as to prevent the power supply mechanism 20 from supplying electric energy to the atomization sheet 131. Therefore, by means of the symmetrical arrangement of the two conductive elements 127, when a user slantly sucks, the situation that the liquid level is too low before the atomizing sheet 131 is exposed out of the liquid level can be effectively detected, and therefore the atomizing sheet 131 is effectively prevented from being easily exposed out of the liquid level in a tilted state and being burnt. It will be readily appreciated that in other embodiments of the present invention, only one conductive element 127 may be disposed in the atomizer 10, for example, when a user holds the electronic atomization device 100 vertically for suction, only one conductive element 127 may be required for detection.

Further, when the two conductive elements 127 are symmetrically arranged about the atomizing plate 131 along the axis of the atomizer 10, the suction nozzle 15 can be configured to be flat, and the flat suction nozzle can enable a user to perform suction in a fixed manner, and the long axis direction of the suction nozzle 15, i.e. the flat extending direction of the suction nozzle 15 is perpendicular to the central connecting line of the two conductive elements 127, which is shown as the long axis direction of the suction nozzle 15 in R1 in fig. 9. Furthermore, when a user sucks in an inclined state, the two conductive elements 127 are opposite to the atomizing sheet 131, one is positioned above the atomizing sheet 131, and the other is positioned below the atomizing sheet 131, so that the situation that the liquid level is too low before the atomizing sheet 131 is exposed out of the liquid level can be further ensured during the inclined state of sucking, and the atomizing sheet 131 is effectively prevented from being burnt due to the exposure of the liquid level during the inclined state of sucking.

It should be noted that, in other embodiments of the present invention, the suction nozzle 15 may also be designed to be circular, and at this time, since the suction nozzle 15 is circular, the user can suck through the suction nozzle 15 in any manner, and the inclination direction of the electronic atomization device 100 is unpredictable. In order to prevent the atomizing plate 131 from exposing the liquid surface when the user tilts for sucking, thereby causing dry burning, at least 4 conductive elements 127 may be provided in the atomizer 10, and at least 4 conductive elements 127 may be uniformly arranged around the atomizing plate 131, for example, when 4 conductive elements 127 are provided, any two conductive elements 127 are separated by 90 degrees. When a user sucks in any inclined direction, at least one conductive element 127 exposes the liquid surface before the atomizing plate 131 exposes the liquid surface, and the controller controls the electric core 21 to supply electric energy to the atomizing plate 131 only when electric signals of all the conductive elements 127 are detected. Therefore, when the upper end 1271 of at least one conductive element 127 is exposed out of the liquid surface, the first conductive electrode cannot transmit an electric signal to the conductive element 127 through the conductive liquid matrix, and the controller cannot receive signals from all the conductive elements 127, and the controller will cut off the electric connection path between the electric core 21 and the atomizing plate 131, so as to prevent the atomizing plate 131 from being exposed out of the liquid surface in a certain inclined direction and causing dry burning.

Further, in other embodiments of the present invention, a plurality of conductive elements 127 are disposed in the atomizer 10, and the portions of the plurality of conductive elements 127 exposed in the reservoir 17 have different exposure heights, that is, the portions of the plurality of conductive elements 127 exposed in the reservoir 17 and the atomizing plate 131 have different heights. The controller of the power supply mechanism 20 can judge the current liquid level of the liquid matrix by identifying the electric signals sent by the conductive elements 127, so as to judge the current residual capacity of the liquid, and then set different atomization powers according to different liquid capacities, thereby improving the efficiency and achieving the optimal atomization effect.

It should be further noted that the upper end 1271 of the conductive element 127 is exposed to the liquid storage chamber 17 at a proper height, if the exposed position is too high, the liquid level of the liquid matrix may reach the upper end 1271 of the conductive element 127 too early along with the consumption of the liquid matrix, at this time, if the liquid matrix is further consumed, the upper end 1271 of the conductive element 127 may be exposed to the liquid level, and then the controller may cut off the electrical connection between the electric core 21 and the atomizing plate 131, and the atomizer 10 may still have a lot of liquid matrix which is unusable, so that the utilization rate of the liquid matrix in the atomizer 10 is low. However, if the exposed position of end 1271 on conductive element 127 is too low, it may result in less sensitive detection. Therefore, it is preferable that the vertical distance between the upper end 1271 of the conductive element 127 and the atomization plate 131 is not more than one third of the vertical distance between the liquid surface of the liquid medium and the atomization plate 131, and the height range is suitable.

Continuing to refer to fig. 10, fig. 10 shows a perspective view of the smoke tube 16 in one direction. The smoke tube 16 includes a first cylinder 161 and a second cylinder 162 that are arranged opposite to each other in the axial direction, the first cylinder 161 and the second cylinder 162 are both hollow, and the first cylinder 161 and the second cylinder 162 are isolated by an isolation portion 163. The first cylinder 161 is partially inserted into the suction nozzle 15, the first cylinder 161 has an open end, the open end extends into the suction nozzle 15, and the sidewall of the first cylinder 161 is opened with a venting hole 1611 communicating with the inside of the first cylinder 161. The second cylinder 162 also has an open end 1621, the second air inlet pipe 129 extends to the inside of the second cylinder 162 through the open end 1621, most of the aerosol generated by the ultrasonic atomization of the atomization sheet 131 is released to the inside of the second cylinder 162, and the inside of the second cylinder 162 can be used as the atomization chamber 164 of the electronic atomization device 100.

The power supply mechanism 20 is provided with an air inlet hole (not shown) for allowing outside air to enter the electronic atomization device 100, then the outside air flows to the third through hole 1261 of the atomizer 10, then enters the first air inlet pipe 128 through the third through hole 1261, enters the second air inlet pipe 129, and enters the atomization chamber through the second air inlet pipe 129 to form an air inlet channel. Then the aerosol is carried, flows to the air vent 1611 of the first cylinder 161 through the gap between the smoke tube 16 and the housing 11, enters the suction nozzle 15 through the open end of the first cylinder 161, and is finally discharged from the suction nozzle 15 for the user to suck.

The power supply mechanism 20 includes a power supply unit (cell) 21; the MCU (microprocessor) is used as a controller for controlling the power supply unit 21 to supply power to the atomizing plate 131 and is electrically connected with the power supply unit 21; a booster circuit connected to the power supply unit 21, and a high-frequency oscillator circuit electrically connected to the MCU. The MCU is configured to generate a high-frequency PWM oscillation signal, and the MCU can control the atomization plate 131 to vibrate through the PWM signal; the high-frequency oscillation circuit comprises an amplifying circuit for amplifying the PWM signal and a resonance circuit for resonating with the atomizing plate 131; the booster circuit is used to boost the voltage of the power supply unit 21 to a voltage required by the high-frequency oscillation circuit. The high-frequency oscillation circuit is connected with the first conductive electrode and the second conductive electrode of the atomization plate 131, so that a high-frequency oscillation signal is provided for the atomization plate 131, and the first conductive electrode is in direct contact with the liquid matrix, so that the high-frequency oscillation signal can be transmitted to the conductive element 127 through the liquid matrix, and the conductive element 127 can receive the high-frequency oscillation signal. The conductive element 127 is electrically connected with the MCU, so that the conductive element 127 can transmit the high-frequency oscillation signal to the MCU after receiving the signal, and the MCU can determine that the first conductive electrode of the atomizing plate 131 is connected to the conductive element 127 through the liquid matrix according to the oscillation signal. If the MCU does not receive the oscillation signal, it is determined that the first conductive electrode of the atomizing plate 131 is not connected to the conductive element 127.

High frequency PWM oscillating signal that MCU produced produces behind the high frequency oscillation circuit produces the resonance with atomizing piece 131, and atomizing piece 131 can produce the vibration under the effect of resonance, thereby atomizing piece 131 shakes liquid matrix through high frequency vibration's mode (the sound wave that this high frequency vibration produced exceeds people's hearing scope, and is harmless to the human body) produces smog, realizes ultrasonic atomization.

The MCU is configured to output 2 paths of PWM signals, the 2 paths of PWM signals are combined to form a complete PWM signal, one path of PWM signal is sent to the first conducting electrode of the atomizing plate 131 in one half period of the complete PWM signal, the other path of PWM signal is sent to the second conducting electrode of the atomizing plate 131 in the other half period of the complete PWM signal, and the 2 paths of PWM signals have opposite directions, so that the amplitude of the atomizing plate 131 can be controlled by the controller MCU through the PWM signal, half-wave detection can be further realized on the conducting element 127, namely, detection is carried out when only one path of PWM signal is sent to the atomizing plate 131, and the conducting element 127 can accurately detect the liquid level height of the liquid matrix.

Specifically, when the MCU controls only one of the PWM signals to be transmitted to the atomizing plate 131, the atomizing plate 131 vibrates only in a single direction, and the amplitude is small, and at this time, the fluctuation of the liquid level of the liquid substrate is small, and the liquid level is stable; when the MCU controls 2 PWM signals to be transmitted to the atomizing plate 131, the atomizing plate 131 vibrates in two directions, and the amplitude is large, and the fluctuation of the liquid level of the liquid matrix is large. Therefore, in order to facilitate the conductive element 127 to accurately detect the liquid level height, after the atomizer 100 is started, the MCU can first control one of the two paths of PWM signals to be transmitted to the first conductive electrode of the atomizing plate 131, and simultaneously control to close the other of the two paths of PWM signals output to the second conductive electrode of the atomizing plate 131, so that the atomizing plate 131 vibrates only in one direction, the amplitude of the vibration in one direction is small, the fluctuation of the liquid level of the liquid substrate is not large when the atomizing plate 131 vibrates in one direction, the liquid level is stable, the conductive element 127 can accurately detect the current liquid level height, after the MCU detects the liquid level height, the MCU can control the other path of PWM signal to be transmitted to the second conductive electrode of the atomizing plate 131, so that the atomizing plate 131 vibrates in two directions, the amplitude of the atomizing plate 131 is increased, and ultrasonic atomization of the liquid substrate is started to generate smoke.

Further, a signal attenuation circuit is further provided in the power supply mechanism 20, and the conductive element 127 is electrically connected to the MCU through the signal attenuation circuit. The I/O port of the MCU can only accept electrical signals with a relatively low voltage, and the voltage of the oscillation signal is relatively high, so that the voltage of the oscillation signal needs to be attenuated to a range that the MCU can accept by the signal attenuation circuit, and if the oscillation signal is directly input to the MCU, the MCU is easily damaged.
