With reference to fig. 6 and fig. 2, in order to conduct the liquid matrix to the ultrasonic atomization assembly 70 for atomization, the ultrasonic atomization module 100 further includes the first liquid guiding element 40 and the second liquid guiding element 60, the first liquid guiding element 40 and the second liquid guiding element 60 are both disposed in the first receiving chamber 81, and the first liquid guiding element 40 and the second liquid guiding element 60 together deliver the liquid matrix to the ultrasonic atomization assembly 70. In this embodiment, the first liquid guiding element 40 and the second liquid guiding element 60 may be flexible fibers, such as cotton fibers, non-woven fabrics, glass fiber ropes, etc., or include porous materials with microporous structures, such as porous ceramics, etc., specifically, in this embodiment, the first liquid guiding element 40 is configured as a block-shaped porous body supported between the ultrasonic atomizing assembly 70 and the support 20, and an end of the porous body facing the support 20 is provided with a sinking groove 41. The second liquid guiding element 60 is made of a fiber material with hygroscopicity, for example, liquid absorbing cotton made of cotton fiber in the embodiment, and is attached to the ultrasonic atomization component 70, the porous body is at least partially supported on the liquid absorbing cotton 60, the liquid matrix flows to the sinking groove 41 through the first liquid guiding hole 25 of the bracket 20, and then flows to the liquid absorbing cotton 60 through the micropore structure inside the porous body, and the liquid absorbing cotton 60 conducts the liquid matrix to the core atomization area of the ultrasonic atomization component 70 for atomization. The sealing member 30 is a soft plastic member, and is interference-fitted between the porous body 40 and the holder 20 to seal an assembly gap between the porous body 40 and the holder 20.

It should be noted that, in other embodiments of the present invention, the second liquid guiding element 60 may not be provided, and the porous body 40 may be directly supported on the ultrasonic atomizing assembly 70, and the liquid matrix may be directly transmitted to the ultrasonic atomizing assembly 70 through the porous body 40 for atomization. In the embodiment, the second liquid guiding element 60 is attached to the ultrasonic atomization assembly 70, and splashed liquid drops generated during atomization of the ultrasonic atomization assembly 70 can be adsorbed by the second liquid guiding element 60.

Continuing to refer to fig. 7, fig. 7 shows an exploded view of ultrasonic atomization assembly 70 from one perspective. Ultrasonic atomization assembly 70 includes a first end cap 71, a second end cap 72, an atomization sheet 73, a second silicone seat 74, a resistor plate 75, and a conductive spring 76. The first end cap 71 has a first accommodating chamber 711, the second end cap 72 has a second accommodating chamber 721, the first end cap 71 and the second end cap 72 are disposed opposite to each other to form a third accommodating chamber 77 between the first end cap 71 and the second end cap 72, and the atomizing sheet 73, the second silicone seat 74, the resistor plate 75 and the conductive spring 76 are all located in the third accommodating chamber 77.

Since the liquid absorbent cotton 60 is attached to the atomizing sheet 73, the atomizing sheet 73 is generally made of a weak material, and in order to prevent the atomizing sheet 73 from being broken by rigid pressing, the second liquid guiding element 60 is preferably made of a soft material, for example, in this embodiment, the liquid absorbent cotton is used as the second liquid guiding element 60, and the porous body 40 is supported on the liquid absorbent cotton 60 to relieve the rigid pressing of the porous body 40 on the atomizing sheet 73. While the core atomization area of the atomization sheet 73 is generally located in the center area of the atomization sheet 73, the absorbent cotton 60 needs to cover the core atomization area of the atomization sheet 73.

In order to provide a space for releasing the aerosol generated by the ultrasonic atomization assembly 70 after atomization, the porous body 40 and the atomization sheet 73 define an atomization chamber 78. Specifically, the porous body 40 has a first support portion 42 and a second support portion 43 facing each other, which extend toward the end surface of the atomizing plate 73, as shown in fig. 8 and 2. The first support 42 and the second support 43 are at least partially supported on the absorbent cotton 60 to cooperatively define an atomization chamber 78. The first supporting portion 42 and the second supporting portion 43 span the core area of the atomizing plate 73, that is, the first supporting portion 42 and the second supporting portion 43 are distributed on two sides of the core area of the atomizing plate 73, so as to prevent the first supporting portion 42 and the second supporting portion 43 from shielding the core atomizing area of the atomizing plate 73, thereby affecting the ultrasonic atomizing effect. Since the absorbent cotton 60 covers the core atomization zone of the atomization sheet 73, the liquid matrix flowing onto the absorbent cotton 60 can be conducted to the core atomization zone of the atomization sheet 73 through the absorbent cotton 60.

It is worth to say that the atomizing chamber 78 needs to meet a certain height requirement, and when the height is lower, the liquid matrix with stronger fluidity on the absorbent cotton 60 is easily taken away, and the user can easily absorb the liquid matrix; and when the height is higher, part of the air current can pass through the place without aerosol above the atomizing chamber 78, the aerosol can not be fully taken out during suction, the aerosol absorbed by a user has thinner concentration, and the satisfaction is poorer. Therefore, the height of the atomizing chamber 78 is set in the range of 1 to 3mm. In addition, the extension length of the first support part 42 and the second support part 43 is set to 0.5 to 1.5mm, and if the extension length is too long, the liquid matrix in the porous body 40 is liable to be unable to be timely supplemented to the liquid absorbing cotton 60, thereby affecting the atomizing function of the atomizing sheet 73 and liable to damage the atomizing sheet 73.

It should be noted that, in order to prevent the pressure applied by the porous body 40 to the atomizing sheet 73 from being too high, the part of the porous body 40 supported on the liquid-absorbing cotton 60 is flat, and the flat supporting manner can effectively increase the supporting area between the porous body 40 and the liquid-absorbing cotton 60, so as to reduce the pressure applied to the liquid-absorbing cotton 60, further reduce the pressure applied to the atomizing sheet 73, and prevent the atomizing sheet 73 from being broken. Simultaneously, first supporting part 42 and second supporting part 43 adopt the mode that flat dress supported with imbibition cotton 60, can also make more inseparabler of imbibition cotton 60 and the laminating of atomizing piece 73, improve atomization effect.

It should be understood that in other embodiments of the present invention, the porous body 40 may not be supported on the liquid-absorbing cotton 60 in the form of the first supporting portion 42 and the second supporting portion 43 which are oppositely arranged, for example, a circular supporting portion may be provided, the atomizing plate 73 is located in the circle of the circular supporting portion, and the circular supporting portion may provide pressure to the liquid-absorbing cotton 60 in the circumferential direction, and also make the liquid-absorbing cotton 60 and the atomizing plate 73 closely contact.

With continued reference to fig. 9, fig. 9 shows a perspective view of the base 80 in one direction. The base 80 is provided with an installation chamber 82, the installation chamber 82 is a part of the first accommodation chamber 81, the ultrasonic atomization assembly 70 is at least partially installed in the installation chamber 82, the base 80 is provided with a first electrode hole 83 and a second electrode hole 84, and a conductive electrode of the ultrasonic atomization assembly 70 can be electrically connected with a power supply mechanism through the first electrode hole 83 and the second electrode hole 84. A seal 85 is disposed between the ultrasonic atomization assembly 70 and the inner wall of the mounting chamber 82 to seal the assembly gap between the ultrasonic atomization assembly 70 and the mounting chamber 82 and prevent the liquid substrate from flowing through the assembly gap between the ultrasonic atomization assembly 70 and the mounting chamber 82 to the first electrode hole 83 or the second electrode hole 84 and leaking out of the ultrasonic atomization module 100. In this embodiment, the first end cap 71 and the second end cap 72 are made of conductive materials, and the first end cap 71 and the second end cap 72 are disposed opposite to each other and contact each other, so as to form the third accommodating chamber 77 on the one hand, and enable the first end cap 71 and the second end cap 72 to serve as one of the conductive electrodes of the ultrasonic atomization assembly 70 and to be electrically connected to the atomization sheet 73 on the other hand.

The second silicone seat 74, the resistance plate 75 and the conductive spring 76 are disposed in the third receiving chamber 77, the second silicone seat 74 has a through hole 741 penetrating through the upper end and the lower end of the second silicone seat 74, the resistance plate 75 has a through hole 751 penetrating through the upper surface and the lower surface of the second silicone seat 75, the conductive spring 76 serves as another conductive electrode of the ultrasonic atomization assembly 70, one end of the conductive spring is electrically connected to the atomization plate 271, and the other end of the conductive spring extends into the second electrode hole 84 through the through hole 741 of the second silicone seat 74 and the through hole 751 of the resistance plate 75, so that an electrical connection terminal of a power supply mechanism used in cooperation with the atomizer 100 can be electrically connected to the conductive spring 76 through the second electrode hole 72, and similarly, an electrical connection terminal of the power supply mechanism can also be electrically connected to the second end cap 72 through the first electrode hole 83, and then electrically connected to the atomization plate 73 through the first end cap 71, so that the electrical connection terminal of the power supply mechanism can be electrically connected to the ultrasonic atomization assembly 70 through the first electrode hole 83 and the second electrode hole 84, and the ultrasonic atomization assembly 70 can provide electric energy required for ultrasonic atomization.

In this embodiment, in order to make the electrical connection terminal of the power supply mechanism and the conductive spring 76 have good contact when electrically connected, the conductive spring 76 is designed to be spiral, a channel 761 for inserting the electrical connection terminal of the power supply mechanism is formed inside the conductive spring 76, one end of the conductive spring 76 is electrically connected to the atomizing sheet 73, and the other end extends into the second electrode hole 84. Further, in order to prevent the electrical connection terminal of the power supply mechanism from being in a suspended state and having poor contact with the conductive spring 76 when the electrical connection terminal of the power supply mechanism is inserted into the channel 761 of the conductive spring 76, the end of the conductive spring 76 extending to the second electrode hole 84 is configured to be bent toward the central region of the second electrode hole 84, so that the electrical connection terminal of the power supply mechanism can be in good contact with the conductive spring 76, as shown in fig. 10.

It should be noted that, by the arrangement of the first end cap 71 and the second end cap 72, when the assembly is generated, the atomizing sheet 73 can be installed in the first accommodating chamber 712 through the first open end 711 by the atomizing sheet 73, the second silicone seat 74, the resistance plate 75 and the conductive spring 76 can be installed in the second accommodating chamber 722 through the second open end 721, so that the atomizing sheet 73, the second silicone seat 74, the resistance plate 75 and the conductive spring 76 are all installed in the third accommodating chamber 77, and finally, the first end cap 71 and the second end cap 72 are fixedly connected to form the ultrasonic atomizing assembly 70 as an individual module, and the first end cap 71 and the second end cap 72 can be used as a housing portion of the ultrasonic atomizing assembly 70.

The conventional ultrasonic atomization assembly 70 is generally assembled by a structure including an atomization sleeve (not shown) and a top ring (not shown), or an atomization sleeve (not shown) and a bottom ring (not shown). When the atomizing sleeve and the top ring structure are adopted, the atomizing sheet 73, the second silica gel seat 74, the resistance plate 75 and the conductive spring 76 are sequentially loaded into the atomizing sleeve from top to bottom during assembly, and finally the top ring is riveted on the top of the atomizing sleeve, so that all parts are fixed in the atomizing sleeve to form the ultrasonic atomizing assembly 70. However, at this time, since the atomization plate 73 is finally installed from the top, the atomization plate 73 is jacked up by the conductive spring 76 and is in a suspended state, the circumference of the atomization plate 73 is easily separated from the limit groove and is in an unlimited state, and thus the atomization plate 73 is easily crushed when being installed.

When the atomizing sleeve and the bottom ring structure are adopted, all parts are sequentially arranged in the atomizing sleeve from bottom to top during assembly, and finally the bottom ring is riveted at the bottom of the atomizing sleeve, so that all the parts are fixed in the atomizing sleeve to form the ultrasonic atomizing assembly 70.
