As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Fig. 1 is a schematic view of an ultrasonic atomization apparatus provided in an embodiment of the present application.

As shown in fig. 1, the ultrasonic atomizing device 100 includes an ultrasonic atomizer 10 and a power supply assembly 20, and the ultrasonic atomizer 10 and the power supply assembly 20 are not detachable.

The ultrasonic atomizer 10 includes a reservoir (not shown), an atomizing assembly 11, and a power supply 20 for supplying electric power to the atomizing assembly 11 to generate high frequency oscillation to atomize the liquid substrate into a liquid mist.

The power supply assembly 20 includes a battery cell 21 and a circuit 22.

The battery cell 21 provides power for operating the ultrasonic atomization device 100. The cell 21 may be a rechargeable cell or a disposable cell.

The circuit 22 may control the overall operation of the ultrasonic atomization device 100. The circuit 22 controls not only the operation of the electrical core 21 and the atomizing assembly 11, but also the operation of other elements in the ultrasonic atomizing device 100.

Fig. 2 is a schematic view of another ultrasonic atomizer provided in the present embodiment, which is different from the example of fig. 1 in that the ultrasonic atomizer 10 is detachably connected to the power supply assembly 20.

As shown in fig. 3-5, embodiments of the present application provide a nebulizing assembly 11 comprising an ultrasonic nebulizing patch 111, a first electrical connector (112, 115), a resilient conductive element 113, and a second electrical connector 114.

In this example, the ultrasonic atomization sheet 111 includes a substantially circular piezoelectric ceramic base, on the upper surface of which a first electrode 111a is formed and the lower surface of which a second electrode 111b is formed.

The first electrical connection (112, 115) comprises a conductive sleeve 112 and a coupling 115. The ultrasonic atomization plate 111, the elastic conductive element 113 and the second electrical connector 114 are all disposed within the conductive sleeve 112. Specifically, the ultrasonic atomization plate 111 is horizontally disposed near an upper end (first end) of the conductive sleeve 112, the elastic conductive element 113 and the second electric connection piece 114 are disposed between the ultrasonic atomization plate 111 and a lower end (second end) of the conductive sleeve 112, and the conductive sleeve 112 is disposed apart from the second electric connection piece 114 by the elastic conductive element 113.

One region of the elastic conductive element 113 is directly or indirectly electrically connected to the first electrode 111a of the ultrasonic atomization sheet 111, and the other region of the elastic conductive element 113 is directly or indirectly electrically connected to the second electrode 111b, so that a loop is formed among the first electrode 111a, the elastic conductive element 113 and the second electrode 111 b. It should be noted that, one region and the other region of the elastic conductive element 113 may be any two regions or portions of the elastic conductive element 113, as long as the first electrode 111a and the second electrode 111b are prevented from being directly contacted to cause a short circuit.

In a preferred implementation, as shown in fig. 5 and 8, the elastic conductive element 113 is configured as a cylindrical structure, i.e., includes a cylindrical body, an upper end 113a (proximal end) of the cylindrical body has a plurality of projections 113b, the projections 113b are annular, and the plurality of annular projections 113b are arranged along the radial direction. The lower end 113d (distal end) of the cylindrical body has a portion extending axially downward to form a boss 113 e. The hollow part of the cylindrical body forms a housing chamber 113c, and the housing chamber 113c extends from the upper end 113a to the lower end 113 d; the receiving chamber 113c has a shape matching the shape of the second electrical connector 114 for receiving the second electrical connector 114 to fix the second electrical connector 114. The projection 113b abuts against the lower surface of the ultrasonic atomization sheet 111 to support the ultrasonic atomization sheet 111. The side walls of the resilient conductive element 113 abut at least partially against the inner wall of the conductive sleeve 112 to form an electrical connection.

The elastic conductive element 113 is formed by molding a mixture of an elastic material and metal particles, and the elastic material may be silicon gel, soft gel, or the like. Thus, the elastic conductive element 113 itself has a certain resistance, and the resistance value thereof is greater than 500K Ω; alternatively, greater than 800K Ω; alternatively, greater than 1 Μ Ω; or more than 1M Ω and less than 2M Ω; the elastic conductive member 113 reduces the transmission of vibration of the ultrasonic atomization sheet 111 on the one hand by its own elasticity; on the other hand, the ultrasonic atomization sheet 111 is in contact with the first electric connecting piece and the second electric connecting piece 114 to form electric connection, so that a loop is formed to consume energy stored by the ultrasonic atomization sheet 111 after the ultrasonic atomization sheet 111 is electrified and disconnected, the ultrasonic atomization sheet 111 is guaranteed to work normally after being electrified again, and the phenomenon that other electronic components are burnt due to release of instantaneous high voltage after the ultrasonic atomization sheet 111 is electrified again is avoided. Since the resistance of the elastic conductive member 113 itself is large, and the resistance of the ultrasonic atomization sheet 111 is small; therefore, the elastic conductive member 113 consumes very little energy when the ultrasonic atomization device 111 is operated. It will be appreciated that the resilient conductive element 113 also has a sealing effect, and by virtue of being in contact with the lower surface of the ultrasonic atomization sheet 111 and the inner wall of the conductive sleeve 112, leakage or flow of the liquid matrix within the cylindrical body towards the lower end 113d is avoided.

In this example, since the elastic conductive element 113 is used without providing a separate resistor plate, the distance d1 between the upper end and the lower end of the conductive sleeve 112 is much smaller than that of the conventional case, and the general d1 is 5mm to 6 mm; or, between 5.2mm and 6 mm; or, between 5.4mm and 6 mm; alternatively, between 5.5mm and 6 mm.

The lower surface of the ultrasonic atomization sheet 111 is faced to the second electric connection member 114 such that one end of the second electric connection member 114 abuts against the second electrode 111b formed on the lower surface of the ultrasonic atomization sheet 111 to be held in contact to form an electric connection, and the other end of the second electric connection member 114 extends toward the lower end of the conductive sleeve 112. The upper end of the conductive sleeve 112 has a radially extending extension (not shown in the drawings) that abuts against the first electrode 111a formed on the upper surface of the ultrasonic atomization sheet 111 to be held in contact and thus electrically connected.

It should be noted that the first electrode 111a and the second electrode 111b on the ultrasonic atomization sheet 111 are not limited to the case of the drawings. In other examples, the first electrode 111a and the second electrode 111b may be disposed on both sides of the ultrasonic atomization sheet 111, may be disposed on one side, and may be disposed on the same surface of the ultrasonic atomization sheet 111 (e.g., both disposed on the lower surface of the ultrasonic atomization sheet 111). With the position change of the first electrode 111a and the second electrode 111b, the structures of the elastic conductive element 113, the first electrical connectors (112, 115) and the second electrical connector 114 can be changed correspondingly; for example: the elastic conductive member 113 may be electrically connected to the first electrode 111a and the second electrode 111b at one side of the ultrasonic atomization sheet 111; the elastic conductive element 113 may be wrapped around the ultrasonic atomization sheet 111, and electrically connected to the first electrode 111a on one side and the second electrode 111b on the other side.

The coupling member 115 is disposed near the lower end of the conductive sleeve 112 and held on the boss 113 e. The coupling member 115 is in the shape of a ring and is fitted over the boss 113e, and the coupling member 115 is held in contact with the conductive sleeve 112 to form an electrical connection. In this way, when the atomization assembly 11 is coupled with the battery core 21, the lead wire can be advantageously welded to the other end of the coupling member 115 and the second electrical connection member 114.

In the example of fig. 3-8, the first electrical connector (112, 115) comprises a conductive sleeve 112 and a coupling 115, i.e. the first electrical connector is formed of 2 or more separate parts. In other examples, it is also possible, in contrast to the examples of fig. 3-8, that the first electrical connection is realized by one or integrally formed structural parts.

In the example of fig. 3-8, the elastic conductive element 113 is in contact with the first electrical connector to form an electrical connection and the elastic conductive element 113 is in contact with the second electrical connector 114 to form an electrical connection, i.e. indirectly electrically connected to the first electrode 111a via the first electrical connector and indirectly electrically connected to the second electrode 111b via the second electrical connector 114. In contrast to the examples of fig. 3-8, it is also possible in other examples that the elastic conductive element 113 is not held in contact with the first electrical connector, and that the elastic conductive element 113 is not held in contact with the second electrical connector 114; specifically, the elastic conductive element 113 is directly in contact with the first electrode 111a to form an electrical connection, and the elastic conductive element 113 is directly in contact with the second electrode 111b to form an electrical connection. Further, it is also possible that the elastic conductive element 113 is in contact with and electrically connected to the first electrode 111a and the first electrical connector, and the elastic conductive element 113 is in contact with and electrically connected to the second electrode 111b and the second electrical connector 114.

In the example of fig. 3-8, the atomizing assembly 11, which is comprised of the ultrasonic atomization plate 111, the first electrical connector (112, 115), the resilient conductive element 113, and the second electrical connector 114, is disposed in the ultrasonic atomizer 10 (either removable or non-removable from the power module 20). In contrast to the examples of fig. 3-8, in other examples, the atomizing assembly 11, which is comprised of the ultrasonic atomizing plate 111 and the resilient conductive member 113, may be disposed within the ultrasonic atomizer 10 (either removable or non-removable from the power supply assembly 20); it is also possible that the first electrical connector (112, 115) and the second electrical connector 114 are provided in the power module 20; at this point, first electrical connections (112, 115) and second electrical connections 114 may be electrically connected to the electrodes in the ultrasonic atomization sheet, either directly or indirectly.

step S13, installing a second electric connecting piece and an elastic conductive element in the conductive sleeve, wherein the second electric connecting piece is abutted against the second electrode of the ultrasonic atomization sheet, and the elastic conductive element is abutted against the ultrasonic atomization sheet.
