In one embodiment, the conductive terminals 1501 are metal terminals; in another embodiment, the conductive terminals 1501 are non-metallic terminals with a conductive coating applied to the surface.
Host 200 also includes an electrical connector (not shown) that is electrically connected to host 200, wherein upon assembly of nebulizer 100 and host 200, the electrical connector is electrically connected to sensing electrode 1502 and thus electrically connected to conductive terminal 1501. Wherein the electric connecting piece can be a conductive rod or a conductive blind pipe and the like.
In this embodiment, the detection element 150 is integrally hollow and tubular, the liquid matrix in the buffer cavity 1201 is further filled in the detection element 150, and the electrical connection member of the host 200 is inserted into the detection electrode 1502 and electrically connected to the detection electrode 1502 through the liquid matrix.
As can be understood, the detection element 150 and the heat generating member 1301 form a detection circuit through the liquid matrix, and are used for detecting the amount of the liquid matrix in the buffer cavity 1201; the controller 220 controls the one-way valve 140 to be closed or opened according to the connection or disconnection of the detection circuit, so that the liquid storage cavity 1101 is not connected or communicated with the cache cavity 1201.
Alternatively, the conductive terminals 1501 of the detecting element 150 may be conductive strips, conductive rods, or the like, which is not particularly limited in this application.
In one embodiment, the conductive terminals 1501 are conductive sheets, and any one of the conductive terminals 1501 and the heat generating member 1301 can form a detection circuit through a liquid matrix, wherein the conductive terminal 1501 and the heat generating member 1301 are respectively used as one of a positive electrode and a negative electrode of the detection circuit. When the liquid level of the liquid matrix in the buffer cavity 1201 is lower than the height of the heating member 1301, the detection circuit is broken, the controller 220 controls the one-way valve 140 to be opened, the liquid storage bin 110 is communicated with the buffer cavity 1201, so that the liquid matrix in the liquid storage cavity 1101 enters the buffer cavity 1201 through the lower liquid hole 1102 and the liquid inlet hole 1202 to replenish the liquid matrix in the buffer cavity 1201; when the liquid level of the liquid matrix in the buffer cavity 1201 is gradually higher than the height of the heating member 1301, the liquid matrix simultaneously contacts the heating member 1301 and the conductive terminal 1501, namely the heating member 1301 and the conductive terminal 1501 are electrically connected, the detection circuit is conducted, and since the buffer cavity 1201 needs to be filled with enough liquid matrix to heat and atomize, after the controller 220 responds to the conduction of the detection circuit for a certain time, the one-way valve 140 is controlled to be closed, so that the liquid guide channel of the lower liquid hole 1102 communicated with the liquid inlet hole 1202 is cut off, namely the liquid storage cavity 1101 is not communicated with the buffer cavity 1201, and liquid leakage caused by excess liquid matrix of the buffer cavity 1201 is avoided.

For example, the number of the conductive terminals 1501 is multiple, and the conductive terminals 1501 are distributed around the atomizing assembly 130, so that tilt detection can be performed, and it is avoided that when the electronic atomizing device 300 tilts relatively, a detection circuit on one side is broken, and further when more liquid matrixes exist in the buffer cavity 1201, more liquid is injected into the buffer cavity 1201 again, so that the liquid in the buffer cavity 1201 is overloaded, and a liquid leakage condition is likely to occur.
Optionally, the number of the conductive terminals 1501 may be 2, 3, or 4, and the like, and the conductive terminals are arranged around the atomizing assembly 130, and when at least one detection circuit formed by the conductive terminals 1501 and the heating member 1301 is a passage, the one-way valve 140 continues to be kept in a closed state, that is, the electronic atomizing device is prevented from blindly injecting liquid into the buffer cavity 1201 in an inclined state; when all the detection circuits formed by the conductive terminals 1501 and the heating member 1301 are open-circuited, the controller 220 controls the one-way valve 140 to open so as to inject liquid into the buffer cavity 1201.
Optionally, in another embodiment, the number of the conductive terminals 1501 is two, the two conductive terminals 1501 and the heating member 1301 constitute two detection circuits respectively through a liquid matrix, wherein one conductive terminal 1501 and the heating member 1301 constitute a first branch, the other conductive terminal 1501 and the heating member 1301 constitute a second branch, the first branch and the second branch may correspond to a first preset value and a second preset value for detecting a liquid level in the buffer cavity 1201, respectively, wherein the first preset value is smaller than the second preset value, and the first preset value and the second preset value may be set according to requirements in actual production, which is not limited in this embodiment.
