Of course, the first conductive member 3 and/or the second conductive member 4 may also be a metal conductive sheet or the like.

The embodiment of the utility model provides a basic work principle of atomizer: when being full of atomized liquid 6 in stock solution chamber 21, each electrically conductive piece 4 all contacts with atomized liquid 6 in the stock solution chamber 21, because atomized liquid 6 in the stock solution chamber 21 has electric conductivity, only need carry out electrically conductive connection with atomized liquid 6 in the stock solution chamber 21 with power supply unit's second wiring utmost point, then atomized liquid 6 in the stock solution chamber 21 can act as each electrically conductive piece 4 and power supply unit's second wiring utmost point and carry out electric connection's conductor. In this way, each first conductive member 3 electrically connects the corresponding heating unit 111 to the first connection terminal of the power supply device, so that each heating unit 111 can be connected to the conductive circuit, the power supply device can supply power to each heating unit 111, each heating unit 111 generates heat after being electrified so as to heat and atomize the atomized liquid 6 transmitted to the corresponding heating unit 111, and the aerosol formed by atomizing the atomized liquid 6 is led out of the atomizer through the air outlet channel 22. As the atomized liquid 6 in the liquid storage cavity 21 is continuously consumed, the liquid level of the atomized liquid 6 also drops, the second conductive members 4 sequentially separate from the atomized liquid 6 according to the sequence of positions, and after the second conductive members 4 separate from the atomized liquid 6, the corresponding heating units 111 are disconnected from the circuit loop without generating heat. In addition, as the atomized liquid 6 in the liquid storage chamber 21 is continuously consumed, the liquid level of the atomized liquid 6 is also reduced, and the liquid guiding rate of the porous liquid absorbing member 12 is correspondingly reduced. In this way, the number of the heating units 111 connected in the circuit loop in parallel is gradually reduced, so that the resistance of the connected circuit loop is gradually increased, and under the condition that the power supply device outputs electric energy at constant voltage, as can be known from the electric heating calculation formula, as the atomization liquid 6 in the liquid storage cavity 21 is continuously consumed, the total resistance of the heating element 11 is increased, and the total heating power of the heating element 11 is reduced accordingly. Thus, the total heat generation power is reduced to be adapted to the reduction of the liquid guiding speed of the porous liquid absorbing member 12, and the phenomenon of dry burning of the porous liquid absorbing member 12 can not be caused. Until the atomized liquid 6 in the liquid storage cavity 21 is exhausted, all the second conductive members 4 are separated from the atomized liquid 6, that is, the heating unit 111 at the lowest position is electrically disconnected from the circuit loop, and the heating unit 111 at the lowest position does not generate heat after being powered off, and at this time, the whole heating member 11 is electrically disconnected from the circuit loop without generating heat. Therefore, after the atomized liquid 6 in the liquid storage cavity 21 is consumed, the whole heating element 11 formed by connecting the heating units 111 in parallel is powered off and does not generate heat, so that the porous liquid absorbing element 12 is not burnt.

The embodiment of the utility model provides an atomizer compares with prior art, and the piece 11 that generates heat is by at least two monomer 111 parallel connection components that generate heat, respectively generates heat and all is equipped with the electrically conductive piece of first 3 and the electrically conductive piece of second 4 on the monomer 111. When the liquid atomizing device is used, the corresponding heating monomers 111 are electrically connected with the first wiring electrode of the power supply device only through the first conductive pieces 3, the second conductive pieces 4 extend into the atomized liquid 6 in the liquid storage cavity 21, and the second conductive pieces 4 are arranged at intervals in the vertical direction, so that when the second conductive pieces 4 contact the atomized liquid 6 in the liquid storage cavity 21, the atomized liquid 6 with conductivity can serve as a conductor between the second conductive pieces 4 and the second wiring electrode of the power supply device, the power supply device can supply power to the heating monomers 111 at the same time, and the heating monomers 111 generate heat after being electrified to heat and atomize the atomized liquid 6. As the atomized liquid 6 in the liquid storage chamber 21 is consumed continuously, the second conductive members 4 are sequentially separated from the atomized liquid 6 according to the order of the positions, so that the corresponding heating units 111 are sequentially powered off and do not generate heat. And, as the atomized liquid 6 in the liquid storage cavity 21 is consumed continuously, the number of the heating monomers 111 connected in parallel to the circuit loop is reduced gradually, so that the total heating power of the heating element 11 is ensured to be adapted to the liquid guiding rate of the porous liquid absorbing element 12, and the porous liquid absorbing element 12 is prevented from being burnt. In addition, after the atomized liquid 6 in the liquid storage cavity 21 is completely consumed, all the second conductive members 4 are separated from the contact with the atomized liquid 6, and the whole heating member 11 formed by connecting the heating units 111 in parallel is powered off and does not heat, so that dry burning of the porous liquid absorbing member 12 is effectively prevented.

The aerosol formed by the atomization of the atomized liquid 6 is first released intensively to the atomization channel 121 and then led out of the atomizer via the air outlet channel 22. Along with the atomizing liquid 6 in the liquid storage cavity 21 is continuously consumed, the liquid level of the atomizing liquid 6 can also be lowered, each second conductive piece 4 is sequentially separated from the atomizing liquid 6 according to the height sequence of the position, after the second conductive pieces 4 are separated from the atomizing liquid 6, the corresponding heating monomer 111 can be disconnected with the circuit loop without generating heat, and the part, corresponding to the heating monomer 111 which does not generate heat when the power is off, on the porous liquid absorbing piece 12 can also be separated from the atomizing liquid 6 without absorbing liquid, so that the part, separated from the contact with the atomizing liquid 6, on the porous liquid absorbing piece 12 cannot be burned dry, and the situation that the upper part of the porous liquid absorbing piece 12 is insufficient in liquid absorption due to the fact that the upper part of the porous liquid absorbing piece 12 is not heated continuously by the heating piece 11 under the situation that the liquid absorption is insufficient in liquid absorption does not occur due to the contact with the atomizing liquid 6 is effectively avoided.

When the liquid storage device is used, the corresponding heating monomers 111 are electrically connected with the first wiring poles of the power supply device only through the first conductive pieces 3, the second conductive pieces 4 extend into the atomized liquid 6 in the liquid storage cavity 21, and the height positions of the second conductive pieces 4 are consistent with the height positions of the corresponding heating monomers 111, so that when the second conductive pieces 4 are in contact with the atomized liquid 6 in the liquid storage cavity 21, the atomized liquid 6 with conductivity can serve as a conductor between the second conductive pieces 4 and the second wiring poles of the power supply device, the power supply device can simultaneously supply power to the heating monomers 111, and the heating monomers 111 generate heat after being electrified to heat and atomize the atomized liquid 6. Along with the atomized liquid 6 in the liquid storage cavity 21 is continuously consumed, each second conductive component 4 can be sequentially separated from the atomized liquid 6 according to the height sequence of the positions, so that the corresponding heating monomer 111 is sequentially powered off and does not generate heat, and the part of the porous liquid absorbing component 12 separated from the contact with the atomized liquid 6 cannot be dried. And, as the atomized liquid 6 in the liquid storage cavity 21 is consumed continuously, the number of the heating monomers 111 connected in parallel to the circuit loop is reduced gradually, so that the total heating power of the heating element 11 is ensured to be adapted to the liquid guiding rate of the porous liquid absorbing element 12, and the porous liquid absorbing element 12 is prevented from being burnt. In addition, after the atomized liquid 6 in the liquid storage chamber 21 is completely consumed, all the second conductive members 4 are separated from the atomized liquid 6, and the whole heating member 11 formed by connecting the heating units 111 in parallel is powered off and does not generate heat, so that dry burning of the porous liquid absorbing member 12 is effectively prevented.

And, the second conductive members 4 are arranged at intervals in the vertical direction. Because the atomized liquid 6 in the liquid storage cavity 21 has electrical conductivity, when the second conductive member 4 contacts the atomized liquid 6 in the liquid storage cavity 21, the atomized liquid 6 in the liquid storage cavity 21 can electrically connect the second conductive member 4 with the second connection electrode of the power supply device.

In some embodiments, the atomizer further includes an electrode assembly, which includes a first electrode and a second electrode, the first electrode can electrically connect each first conductive member 3 with a first terminal of the power supply device, the second electrode can electrically connect the atomized liquid 6 in the liquid storage chamber 21 with a second terminal of the power supply device, and after the second conductive member 4 contacts the atomized liquid 6 with conductivity, the heat generating unit 111 corresponding to the second conductive member 4 can be connected to the conducting circuit loop.

When the atomized liquid 6 fills the gap between the conductive body 5 and the corresponding second conductive member 4, the atomized liquid 6 with conductivity can serve as a conductor for electrically conducting the conductive body 5 and the corresponding second conductive member 4, and the heating element 111 corresponding to the second conductive member 4 can be connected to the conducting circuit. The conductor 5 is made of a metal material having good electrical conductivity. In addition, when the number of the electric conductors 5 is set to one, the atomized liquid 6 can have better electric conductivity. When the number of the electric conductors 5 is more than two, the problem of poor electric conduction of the atomized liquid 6 with low electric conductivity can be further avoided.

Referring to fig. 1 and 2, in some embodiments, the conductive body 5 is disposed in the liquid storage cavity 21 adjacent to the second conductive member 4, and the conductive body 5 is integrally formed with the second electrode.

When the atomized liquid 6 fills the gap between the conductive body 5 and the corresponding conductive connection terminal 41, the atomized liquid 6 with conductivity can serve as a conductor for electrically conducting the conductive body 5 and the corresponding conductive connection terminal 41, and the heat generating unit 111 corresponding to the conductive connection terminal 41 can be connected to the conducting circuit. It should be noted that the conductive connection end 41 is made of a metal material having good conductivity.
