In a preferred embodiment, the flue gas delivery pipe 1011 and the main body 101 are integrally molded by using a moldable material, so that the prepared liquid storage cavity a is open or opened towards the far end.

As will be understood in conjunction with fig. 12, ultrasonic atomization assembly 105 includes an ultrasonic atomization sheet 1051, first electrical connectors (1052, 1053), a second electrical connector 1054, an insulating seal 1055, and a resistive plate 1056.

The liquid guiding member 102 is a layer of organic porous fiber in a sheet or block shape extending in the cross-sectional direction of the body 101. When assembled, fluid conducting element 102 is positioned adjacent to and opposite upper surface of reservoir A and is adapted to draw in liquid matrix and transfer liquid matrix away from the lower surface of reservoir A to contacting fluid conducting element 103, as indicated by arrow R1 in FIG. 7. The liquid guiding element 102 is provided with a plug hole for the flue gas transmission pipe 1011 to penetrate through.

In a preferred embodiment, fluid conducting element 102 is made of an organic porous material having elasticity, and exhibits moderate flexibility and rigidity. In implementation, the fluid-directing element 102 has a modulus of elasticity or stiffness that is less than the material of the body 101 or the material defining the reservoir chamber a and greater than the material of the fluid-directing element 103. In particular to hard artificial cotton with Shore hardness of 20-70A. In alternative implementations, liquid conducting element 102 is a rigid rayon comprising oriented polyester fibers, or a rigid rayon or rayon foam made of filamentary polyurethane, or the like. The above drainage element 102 has hardness or flexibility between that of a common flexible plant cotton/non-woven fabric (shore hardness is less than 20A) and that of a rigid porous ceramic/microporous metal (shore hardness is more than 80A), so that the structure is stable and has extremely low expansion after absorbing and infiltrating a liquid matrix, and after assembly, the drainage element 102 is in contact with the inner wall of the main body 101 or the pipe wall of the smoke output pipe 11 between flexible contact and rigid contact, so that on one hand, the liquid storage cavity A can be independently sealed by utilizing the flexibility of the drainage element, and on the other hand, the drainage element has certain hardness and can be easily fixed and maintained. In particular, as shown in the above figures, the shape of the liquid guiding element 102 is substantially adapted to the opening at the lower end of the reservoir a, which in turn may be used to cover, close and seal the reservoir a. In a more preferred embodiment, the fluid conducting element 102 has a Shore hardness of 50-70A, which is approximately equivalent to a thermoplastic elastomer or silicone.

FIG. 8 shows a topographical view of the surface or cross-section of drainage element 102 with the above hardness; the liquid guiding element 102 is substantially in the shape of an ellipse, and the insertion hole matched with the flue gas transmission pipe 1011 is also in the shape of an ellipse. The fluid conducting member 102 is made of oriented fibers, such as polyethylene and/or polypropylene, which are substantially aligned in the longitudinal direction, and the oriented fibers are arranged in the longitudinal direction of the fluid conducting member 102, so that the fluid conducting member 102 has the characteristic of strong bending resistance and thus rigidity. In addition, the liquid guide element 102 prepared by the organic fibers can keep sufficient gaps among fiber materials in the preparation process, so that the liquid matrix can be transferred, and the liquid guide element 102 has proper flexibility. Liquid conducting element 102 having the above oriented fibers is anisotropic. On one hand, the bending strength at least along the length direction is larger than that along the width direction; or on the other hand, has a drainage rate in the length direction that is greater than the drainage rate in the width direction.

Meanwhile, in fig. 8, the surface or the inside of the liquid guiding element 102 is provided with a texture 1021 extending along the length direction; specifically, the grain 1021 is prepared by the textile technology of roller pressing and the like of the oriented fibers, and the space between partial fibers is enlarged by the roller pressing or the spunlace technology and the like in the preparation process, so that macroscopic dents are formed at the positions with the enlarged space, and the width is less than 1mm and is about 0.1-0.5 mm; texture 1021 is formed on or in fluid conducting element 102 by the indentations, which is beneficial for fluid matrix transfer and retention, and for enhanced stiffness.

In the fluid conducting member 102 shown in FIG. 8 of the above embodiment, the fluid conducting member 102 has a length d4 of 16.4mm, a width d5 of 7.80mm, and a thickness of 2.0 mm.

As shown in fig. 9, the liquid guiding member 103 is made of a flexible strip or rod-shaped fiber material, such as cotton fiber, nonwoven fiber, sponge, etc.; the liquid guide member 103 is configured in a deformed shape (substantially a left-right symmetrical structure) in assembly, and includes a first portion 1031 extending in the width direction of the main body 101, a second portion 1032 extending from both end sides of the first portion 1031 in the longitudinal direction of the main body 101 toward the liquid storage chamber a, a third portion 1033 extending from one end of the second portion 1032 in the width direction of the main body 101, and a fourth portion 1034 extending from one end of the third portion 1033 in the longitudinal direction of the main body 101 away from the liquid storage chamber a. In use, the third portion 1033 contacts the lower surface of the fluid conducting element 102 to draw the liquid matrix from the fluid conducting element 102 for transfer by capillary wetting to the second portion 1032 and hence to the first portion 1031. In other examples, the liquid guiding member 103 may be formed by a plurality of parts separated from each other.

In the ultrasonic atomizer, the liquid substrate is sucked from the liquid guiding element 102 through the liquid guiding element 103, so that the liquid substrate is prevented from being excessively or quickly transferred to the ultrasonic atomization sheet 1051 to cause frying oil.

A sealing member 104 for sealing at least a part of the reservoir chamber a is further provided in the main body 101 based on the fitting fixation of the liquid guiding member 103 and the liquid guiding member 102.

Specifically, as shown in fig. 10-11, the seal 104 has a first end 1041 and a second end 1042 opposite in the longitudinal direction of the body 101. The first end 1041 is disposed proximate to the reservoir a and the second end 1042 is disposed proximate to the bottom cover 106. After assembly, first end 1041 abuts a lower surface of wicking element 102 to at least partially provide retention to wicking element 102; the second end 1042 is retained on the ultrasonic atomization assembly 105 and the bottom cap 106.

The sealing member 104 has a pair of through holes 1043 symmetrically arranged along the thickness direction of the main body 101, and the through holes 1043 are in fluid communication with the liquid storage chamber a, i.e. the sealing member 104 can also make the liquid matrix of the liquid storage chamber a be transferred to the first portion 1031 of the liquid guiding element 103 only through the through holes 1043 on the basis of sealing part of the liquid storage chamber a. A smoke channel 1044 formed by hollow penetration is also arranged between the through holes 1043. The flue gas channel 1044 has a proximal end proximate reservoir a and an opposite distal end.

After assembly, the first portion 1031 of the wicking element 103 is retained on the atomizing surface of the ultrasonic atomization plate 1051, the second portion 1032 extends within the through-hole 1043, the third portion 1033 is retained on the first end 1041, and the fourth portion 1034 is retained between the peripheral sidewall 1045 of the seal 104 and the inner wall of the body 101. The distal end of the smoke channel 1044 is in contact with the first portion 1031 and abuts the first portion 1031 against the atomization surface of the ultrasonic atomization sheet 1051. Compared with the scheme of the glass fiber tube in the prior art, on the basis of ensuring the elastic contact with the ultrasonic atomization sheet 1051, because the distal end of the flue gas channel 1044 directly abuts the first part 1031 on the atomization surface of the ultrasonic atomization sheet 1051, the inner wall of the flue gas channel 1044 does not need to be provided with steps to keep the glass fiber tube; thus, the inner wall of the flue gas channel 1044 is substantially flat.

In a preferred embodiment, the distal end portion or portion of the smoke channel 1044 is recessed to form a cutaway slot 10441, and the first portion 1031 and/or the second portion 1032 are disposed along the cutaway slot 10441. The notch 10441 is used to facilitate the transfer of the liquid matrix to the ultrasonic atomization sheet 1051 while ensuring that the liquid-directing element 103 is well bonded to the ultrasonic atomization sheet 1051.

In a preferred embodiment, the inner wall of the through hole 1043 has an inclined surface 1043a disposed near the first portion 1031 and inclined toward the outside of the through hole 1043. In some embodiments, the inner wall of the through hole 1043 has a stepped surface disposed near the first portion 1031, or other arrangements that make the space in the through hole near the first portion 1031 larger. By designing the inclined surface 1043a or the stepped surface, a relief space is formed at the end of the through hole 1043 (near the first portion 1031) to avoid that the sealing member 104 is deformed inward when pressed to clamp the liquid guiding member 103 too tightly and cause too slow oil dropping, so that the liquid matrix smoothly flows to the first portion 1031.

The third portion 1033 is held at a portion of the first end portion 1041, and the portion of the first end portion 1041 constitutes a holding portion. In a preferred implementation, the retaining portion has a surface that matches the shape of the third portion 1033 and faces the reservoir chamber a to retain the third portion 1033. In a further preferred embodiment, the holding portion has an inclined surface 1041a inclined toward a direction away from the third portion 1033 or toward the through hole 1043, i.e., inclined toward the bottom cover 106; the inclined surface 1041a prevents the third portion 1033 from being clamped too tightly by the liquid guiding element 102 and the sealing member 104, which results in too slow down flow of the liquid matrix to the second portion 1032 or the through hole 1043.

In some embodiments, the liquid-absorbing section of the liquid-directing member is supported by the angled face of the seal 104 to maintain intimate contact between the liquid-absorbing section and the outlet of the reservoir or other liquid-directing member. Firstly, the liquid absorbing section is prevented from deviating from the oil outlet under the conditions of high-frequency oscillation of the ultrasonic atomizer 10 or movement of the atomizer and the like, so that the liquid matrix cannot be transmitted to the atomizing surface through the liquid guide element; secondly, the problem that the liquid matrix leaks due to the fact that an overlarge gap exists between the oil outlet of the liquid storage cavity and the liquid guide element is solved; in some embodiments, the wicking section of the wicking element can be the third portion 1033 as described above, or can be a portion of the wicking element that functions as a wicking element; in some embodiments, the angled face of the seal 104 may be the angled face 1041a as described above.

The seal 104 is preferably made of a flexible material such as silicone, thermoplastic elastomer. In an embodiment, the peripheral side wall 1045 of the seal 104 is provided with a rib extending in the circumferential direction, and the rib is used for sealing a gap between the seal 104 and the inner wall of the main body 101.

In a preferred implementation, a liquid buffer space may be provided on the seal 104 for storing the liquid matrix to adjust the efficiency of delivery of the liquid matrix to the ultrasonic atomization sheet 1051. For example, a capillary groove 1043b may be provided on a portion of the inner wall of the through hole 1043 near the reservoir a (it should be noted that the capillary groove may simultaneously replenish air to the reservoir a, relieving the negative pressure of the reservoir a caused by the consumption of the liquid substrate); alternatively, a window or hollow portion surrounding the second portion 1032 is disposed on the peripheral sidewall 1045 of the sealing member 104, so that at least a portion of the second portion 1032 is exposed to the sealing member 104, thereby forming a blocking space to prevent the liquid matrix from flowing or transferring to the first portion 1031 more quickly.

In the design of the gas path for releasing and outputting the aerosol, the inner wall of the smoke channel 1044 and the atomizing surface of the ultrasonic atomizing sheet 1051 jointly define an atomizing chamber; the cross section of the flue gas channel 1044 is smaller than that of the flue gas output pipe 1011, and the other end of the flue gas transmission pipe 1011 is sleeved on the near end of the flue gas channel 1044; thus, the aerosol after ultrasonic atomization is output through the smoke channel 1044 and the smoke output pipe 1011.

In a preferred embodiment, the seal 104 is further provided with an airflow guide 1046 disposed obliquely with respect to the atomization surface, and the distal end portion or partial depression of the smoke channel 1044 forms an airflow slot 10442 to form an airflow outlet of the airflow guide 1046. During suction, external air flows into the ultrasonic atomizer 10 through the air inlets 1063 on the bottom cover 106, flows in through the air inlets of the air flow guide portion 1046, and flows out from the air flow groove 10442 in a direction-changing manner into the smoke channel 1044 or toward the atomizing surface (shown as R2 in the figure), and then the air and the ultrasonically atomized aerosol are output along the smoke channel 1044 and the smoke transmission pipe 1011.

In a further preferred embodiment, the airflow guide portion 1046 includes an airflow guide surface 1046a extending from the flow slot 10442 in a direction obliquely toward the outside of the main body 101 or away from the flow slot 10442, so that the backward airflow can flow out of the flow slot 10442 into the smoke channel 1044 at a preset angle. Like this, through the airflow guide portion 1046 that has this airflow guide face 1046a, the atomizing face blowout that the air can be towards ultrasonic atomization piece 1051 is favorable to the mixture of air and atomizing granule, has promoted the experience of suction and has felt.

In a further preferred embodiment, the thickness (or wall thickness) of the distal end of the smoke channel 1044 is between 0.5mm and 1 mm; preferably, between 0.5mm and 0.8 mm; more preferably, it is between 0.6mm and 0.8 mm. Through the setting of this thickness, guarantee the intensity of flue gas passageway 1044 distal end, when avoiding ultrasonic atomization piece 1051 high frequency vibration, cause the problem that the position that flue gas passageway 1044 distal end and first part 1031 kept in contact turned up the deformation.

The thickness (or wall thickness) of the flue gas channel 1044 may or may not be uniform in the direction extending from the distal end of the flue gas channel 1044 toward the proximal end. In a further preferred embodiment, the thickness of the smoke channel 1044 is gradually increased in the direction extending from the distal end to the proximal end of the smoke channel 1044, while the inner diameter of the smoke channel remains substantially uniform. Therefore, on one hand, the transmission of atomized aerosol is facilitated, on the other hand, the strength of the smoke channel 1044 is further ensured, and the problem that the part of the far-end of the smoke channel 1044, which is kept in contact with the first part 1031, is turned outwards and deformed when the ultrasonic atomization sheet 1051 vibrates in high frequency is avoided. It will be appreciated that the thickness of the flue gas channel 1044 may be progressively greater throughout its extension; or the thickness in the direction of partial extension may be stepwise increasing, for example: the thickness of the lower portion of the flue gas channel 1044 is gradually increased, while the thickness of the upper portion can be maintained uniform.

In a further preferred embodiment, the ultrasonic atomizer 10 further comprises an air passage for allowing air to enter the reservoir a, so as to supply air to the reservoir a and relieve the reservoir a from negative pressure caused by consumption of the liquid medium.

In particular, in an implementation, a portion of the first end 1041 of the seal 104 near the lower surface of the liquid guiding element 102 is recessed to form a recess 1047, the seal 104 is further provided with a gas flow hole 1048 in fluid communication with the recess 1047, and the first end 1041 is further provided with a notch 10411 in fluid communication with the recess 1047.

A gap is provided between the peripheral side wall extending between the upper and lower surfaces of the liquid guide member 102 and the inner wall of the main body 101, the gap forming a first passage portion of the air passage. The first channel portion extends substantially in the longitudinal direction of the body 101. In a preferred embodiment, ribs 1012 are provided on the inner wall of body 101 and abut against liquid conducting element 102 with ribs 1012, so that a gap is maintained between liquid conducting element 102 and the inner wall of body 101 to form a first passage portion. Further, the peripheral side wall extending between the upper and lower surfaces of liquid guiding member 102 has a straight portion 1022 close to rib 1012, and a gap is maintained between liquid guiding member 102 and the inner wall of main body 101 by abutment of straight portion 1022 and rib 1012.

The recess 1047 forms a second channel portion of the air channel and the airflow hole 1048 forms a third channel portion of the air channel. The upper end surfaces of the airflow holes 1048 are higher than the bottom surface of the recess 1047. Through the groove 1047 arranged on the sealing element, on the basis of relieving the negative pressure in the liquid storage cavity A, the air permeability between the upper surface and the lower surface of the liquid guide element 102 is ensured, and the transfer of liquid matrix is facilitated; further, the groove 1047 can buffer the liquid substrate, which is beneficial to preventing liquid leakage.

The gap between the seal 104 and the inner wall of the main body 101 is sealed by the rib provided on the peripheral side wall 1045 of the seal 104. Thus, in use, as the liquid matrix is consumed, when the negative pressure in the liquid storage chamber Aa is gradually increased, the air flowing into the ultrasonic atomizer 10 from the air inlet 1063 can only flow into the groove 1047 through the air flow hole 1048, and then flow to the liquid storage chamber a (shown by R3 in the figure) through the notch groove 10411 and the gap between the liquid guide element 102 and the inner wall of the main body 101. Thereby slowing down the negative pressure in the liquid storage cavity A and ensuring the smooth transfer of the liquid matrix.
