Fig. 1 to 5 are a schematic perspective assembly view, a schematic perspective exploded view, and a schematic cross-sectional view of an electronic atomizer 100 according to an embodiment of the present invention. The electronic atomizer 100 may generally include an atomizing core assembly 100A and a housing 100B. The housing 100B defines a reservoir 100C, the reservoir 100C containing an aerosolizable liquid, such as tobacco tar; the atomizing core assembly 100A is used for absorbing an aerosolizable liquid and generating heat to heat and atomize at least a portion of the absorbed liquid when energized. The atomizing core assembly 100A is disposed in the housing 100B and is in communication with the reservoir space 100C, thereby enabling delivery of the nebulizable liquid in the reservoir space 100C to the atomizing core assembly 100A.

Some embodiments of the atomizing core assembly 100A are first described in detail herein below.

Referring to fig. 3 to 5, according to an embodiment, the atomizing core assembly 100A may mainly include a liquid guiding member 10, a heating member 20, and a vibrator 30.

The liquid guiding element 10 comprises an atomizing surface 11 and a liquid absorbing surface 12, the nebulizable liquid at the atomizing surface 11 is used for being heated and atomized, and the liquid absorbing surface 12 is used for contacting with the nebulizable liquid and conveying the nebulizable liquid to the atomizing surface 11 through a capillary path in the liquid guiding element 10. The liquid guiding element 10 can be made of a material having capillary channels or pores, such as a hard or rigid capillary structure of a porous ceramic body, a porous glass ceramic, a porous glass, a porous metal, and the like. The wicking element 10 is in fluid communication with the reservoir 100C to draw fluid from the reservoir 100C. The atomizing surface 11 of the liquid guiding element 10 may be a lower surface thereof, and the lower surface may be a plane extending along a cross section of the electronic atomizer 100. The liquid absorbing surface 12 can be the surface opposite to the atomizing surface 11; the liquid guiding element 10 may include a first wall portion where the atomization surface 11 is located and two second wall portions extending from two sides of the first wall portion away from the atomization surface, respectively, and a surface of the first wall portion between the two second wall portions forms at least a part of the liquid suction surface 12. The two second wall parts can be simply supporting structures; the structure can also be made of the same material as the liquid guiding element 10, so that the liquid guiding element 10 can be supported in the first sealing element 40 and can also play a liquid guiding role; that is, the opposing inner surfaces of the two second wall portions may also be a part of the liquid suction surface 12. It will be readily appreciated that the two second wall portions define therebetween a laterally extending liquid passage.

The heating element 20 is disposed on the atomization surface 11 and is used for heating at least part of the liquid absorbed by the liquid guide element 10 to generate aerosol when being electrified. The generated aerosol escapes from the atomizing surface 11 and is released into the smoke output channel of the electronic atomizer 100. For example, the heating element 20 may be formed on the atomizing surface 11 of the liquid guiding element 10 by mounting, printing, depositing, or the like. The heating element 20 may be made of stainless steel, nichrome, ferrochromium alloy, titanium metal, etc. in some embodiments. As shown in fig. 4, the heating element 20 is a meandering, circuitous, etc. patterned electrically conductive track and may comprise electrically conductive terminals 21 at both ends; the conductive terminals 21 may be in the form of pads, which may have a square, circular, oval, or the like shape. In some embodiments, the heating element 20 may be a metal mesh or a metal sheet with a number of holes, such as a stainless steel sheet formed into a grid; the metal net or the metal sheet is attached to the atomizing surface 11 of the liquid guiding element 10, or is embedded in the liquid guiding element 10 and close to the atomizing surface 11, and the aerosol can escape through the holes on the metal net or the metal sheet.

The vibrator 30 is connected to the liquid guiding member 10, and the vibrator 30 generates vibration and transmits the vibration to the liquid guiding member 10. For example, the vibrator 30 may be connected in direct contact with the liquid guiding member 10 so as to transmit vibration; alternatively, the vibrator 30 may be indirectly connected to the liquid guiding element 10, as long as the vibration generated when the vibrator 30 operates can be transmitted to the liquid guiding element 10.

In atomizing core assembly 100A of this embodiment, since vibration is transmitted to liquid guiding member 10 using vibrator 30, the nebulizable liquid, such as tobacco tar, will accelerate through the microporous capillary tube inside liquid guiding member 10, thereby ensuring the nebulized oil supply to nebulizing face 11 of liquid guiding member 10. Moreover, since the transportation of the nebulizable liquid inside the liquid guiding element 10 can be accelerated by the vibrator 30, the diameter of the pores inside the liquid guiding element 10 can be set smaller than that of a conventional liquid guiding element, for example, the diameter of the pores can be in the micrometer or submicrometer range, so that the oil locking capability of the liquid guiding element 10 is stronger and the oil is less prone to leak. Correspondingly, the diameter of the air bubbles inside the liquid guiding element 10 with smaller micropore diameter is also smaller, so that the gas can enter the liquid storage space 100C of the electronic atomizer 100 through the micropore capillary inside the liquid guiding element 10 more quickly, the negative pressure value inside the liquid storage space 100C is ensured to be in a more stable reasonable range, and the oil supply and atomization balance of the liquid guiding element 10 of the electronic atomizer 100 are ensured.

In a further embodiment, as shown in fig. 3 to 5, the liquid absorbing surface 12 of the liquid guiding element 10 is disposed opposite to the atomizing surface 11, the liquid guiding element 10 further includes a first side surface 13 extending between the liquid absorbing surface 12 and the atomizing surface 11, and the vibrator 30 is attached to the first side surface 13. By bringing the vibrator 30 into contact with the first side surface 13, the vibration generated by the vibrator 30 during operation can be directly transmitted to the liquid guiding member 10, thereby more effectively accelerating the transportation of the nebulizable liquid inside the liquid guiding member 10.

In further embodiments, as shown in fig. 3-5, the atomizing core assembly 100A may further include a first seal 40. The first sealing element 40 is used for being sleeved on the liquid guide element 10, and the first sealing element 40 is provided with a liquid inlet 42 communicated with the liquid suction surface 12. The first seal 40 is provided with a receiving portion 41, and the receiving portion 41 receives a portion of the vibrator 30. For example, the first sealing member 40 can be disposed over the liquid guiding member 10 from a side of the liquid absorbing surface 12, such that the liquid absorbing surface 12 is in fluid communication with the liquid storage space 100C of the electronic atomizer 100 only in the assembled configuration. The first sealing member 40 may be made of a sealing silicone material. The number of the loading ports 42 may be two, and they may be provided at both sides of the top of the first seal 40. By receiving a part of the vibrator 30 in the receiving portion 41, the position of the vibrator 30 can be further stabilized.

In further embodiments, as shown in fig. 3-5, the atomizing core assembly 100A may further include vibration isolators 50. The vibration insulator 50 serves to press the vibrator 30 against the liquid guide member 10 and to prevent vibration generated when the vibrator 30 operates from being transmitted to members other than the liquid guide member 10. For example, the vibration isolation member 50 may be made of a silicone sealant material, so that the vibrator 30 is pressed against the liquid guiding element 10 by using the elasticity of the silicone sealant, and the vibration generated by the vibrator 30 is not easily transmitted to the housing 100B of the electronic atomizer 100 by using the vibration isolation function of the silicone sealant, thereby avoiding or reducing the discomfort caused by the vibration to the user. In addition, the vibration isolators 50 may also be configured in the form of sealing rings to form a seal with the inner surface of the housing 100B of the electronic atomizer 100.

In a further embodiment, the heating element 20 and the vibrator 30 may be arranged to operate simultaneously. That is, when heating element 20 is energized, vibrator 30 is simultaneously energized such that vibrator 30 imparts a vibration to fluid conducting element 10, causing the aerosolizable liquid to accelerate through fluid conducting element 10 to heating element 20.

In addition, the vibrator 30 may also be configured to adjust the respective amplitude and frequency of vibration of the vibrator 30 by adjusting an input voltage or current. By being arranged to be adjustable in amplitude and vibration frequency, the oil supply requirements of the heating element 20 in different power states can be met, and more freedom of pumping experience is brought to customers.

In further embodiments, the vibrator 30 may include an eccentric vibration motor, a magnetostrictive vibrator, or a piezoceramic vibrator, among other vibration devices.

As previously described, the atomizing core assembly 100A is configured to be disposed within an electronic atomizer 100, and thus, some embodiments of the electronic atomizer 100 are described in detail below.

In one embodiment, as shown in fig. 1-5, the housing 100B of the electronic atomizer 100 includes a housing 60 and a bracket 70.

For example, the upper end of the bracket 70 can be sleeved with the second sealing member 80, so that the nebulizable liquid in the liquid storage space 100C can be communicated only to the liquid absorption surface 12 of the liquid guiding member 10, and can not leak through the joint between the housing 60 and the bracket 70. The second sealing element 80 may be made of a sealing silicone material. The number of the liquid inlet channels 71 can be two, and two liquid inlet channels 71 can be arranged on two sides of the top of the bracket 70; one of the liquid inlet channels 71 is communicated with one of the liquid inlet ports 42, and the other liquid inlet channel 71 is communicated with the other liquid inlet port 42.

In one embodiment, as shown in fig. 3 and 5, the housing 60 has a mouthpiece portion 61, the support 70 defines a first air flow channel 72, and the atomizing surface 11 of the liquid guide member 10 is in air flow communication with the first air flow channel 72 and the mouthpiece portion 61. For example, the mouthpiece section 61 may define the second air flow passage 62, and the lower end conduit 63 of the mouthpiece section 61 may be inserted into the connecting conduit 81 of the second seal 80 so as to communicate with the first air flow passage 72. The first air flow channel 72 may be an L-shaped structure extending downward from the center of the bracket 70 for a distance and turning to one side of the bracket 70. Thus, the mist generated by the atomizing surface 11 can be conveyed upwards to the first air flow channel 72 through the side surface of the liquid guiding element 10, and then is output through the second air flow channel 62.

In addition, as shown in fig. 3 to 5, the electronic atomizer 100 may further include an oil baffle 91, an electrode 92, a base 93, and the like. The base 93 can be inserted into the lower opening of the housing 60 and is in snap fit with the housing 60; the oil baffle 91 is mounted on the base 93 and located below the atomizing surface 11 so as to receive and contain the tobacco tar which may drip through the atomizing surface 11, thereby preventing the tobacco tar from leaking out through the air inlet 94 of the base 93. The vibration isolators 50 may also be mounted to the base 93 by mating structures. The number of the electrodes 92 may be two, i.e., positive and negative electrodes, respectively. The electrode 92 may be inserted from the base 93, through the oil stop 91 and into electrically conductive contact with the conductive terminal 21 of the heating element 20. The oil blocking member 91 may be made of a silica gel material.

In addition, as shown in fig. 1 to 5, the present invention further provides an electronic atomizer 100 according to another embodiment. The electronic atomizer 100 may include: a housing 100B, the housing 100B defining a reservoir space 100C for storing a liquid; a heating element 20 for heating at least part of the liquid generating aerosol when energised; a drainage element 10 for delivering liquid in the reservoir space 100C to the heating element 20; a vibrator 30, said vibrator 30 being connected to said drainage element 10 for generating and transmitting vibrations to said drainage element 10 to increase the efficiency of said delivery. These housing 100B, heating element 20, liquid conducting element 10 and vibrator 30 may be the same as the features in the previous embodiments and will not be described here. In this embodiment, the electronic atomizer 100 may further comprise a power source and a controller for controlling the power source to provide power to the heating element 20 and the vibrator 30, thereby causing the heating element 20 to heat at least a portion of the liquid-generating aerosol and causing the vibrator 30 to vibrate.

Further, the heating element 20 and the vibrator 30 are arranged to operate simultaneously. For example, the power source may be controlled by the controller to simultaneously provide power to the heating element 20 and the vibrator 30.

Further, the vibrator 30 is arranged to adjust the respective amplitude and vibration frequency of the vibrator 30 by adjusting the input voltage or current. For example, the input voltage or current of the power supplied from the power source to the vibrator 30 may be controlled by the controller, thereby adjusting the corresponding amplitude and vibration frequency of the vibrator 30.
