Description

Technical Field

[0001] The embodiments of the present application relate to the field of electronic atomization technology, and in particular to an electronic atomization device and a bracket for the electronic atomization device. Background Art

[0002] Smoking articles (eg, cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. People have attempted to replace these tobacco-burning articles by creating products that release compounds without combustion.

[0003] An example of such a product is a heating device that releases compounds by heating rather than burning a material. For example, the material may be tobacco or other non-tobacco products that may or may not contain nicotine. As another example, there are aerosol providing products, such as so-called electronic atomization devices. These devices typically contain a liquid that is heated to vaporize it, thereby producing an inhalable aerosol. Known electronic atomization devices connect the liquid storage chamber to the external atmosphere through a ventilation channel, so as to allow external air to enter the liquid storage chamber when the negative pressure in the liquid storage chamber exceeds a predetermined threshold value, so as to alleviate or reduce the negative pressure in the liquid storage chamber.

[0092] Or in some other variations of the embodiments, the end cap 20 is tightly combined with the second shell 12 by riveting or interference fit, so that the end cap 20 cannot be removed from the distal end 120 of the second shell 12 to replace the battery cell 70 .

[0121] according to Fig.13 and Fig.14 As shown, the first accommodating cavity 610 is open at the first end of the bracket 60; the axial length of the first accommodating cavity 610 is greater than the thickness of the sheet-like first liquid-conducting element 50. Then the first liquid-conducting element 50 is assembled into the first accommodating cavity 610 from the first end; and after assembly, the first liquid-conducting element 50 is not flush with the first end of the bracket 60, for example Fig.13 and Fig.14 There is a distance d1 between them. In some embodiments, the distance d1 is about 5-10 mm.

[0122] according to Figures 3 to 14 As shown, the third support portion 63 has an exposed area that is not surrounded or enclosed by the sealing element 80; a second connection structure 633 such as a slot or a protrusion can be arranged on the exposed area of ​​the third support portion 63 outside the sealing element 80; and after assembly, the second connection structure 633 establishes a mechanical connection with the housing 10 / first shell 11. And according to Fig.11 , Fig.12 and Fig.15 As shown, the third supporting portion 63 is also provided with abutting bosses 634 arranged around the third supporting portion 63 ; during assembly, the first housing 11 is assembled against the abutting bosses 634 .

[0123] according to Fig.15 As shown in the figure, the circumferentially extending abutment boss 634 has a curved positioning structure 6341. The positioning structure 6341 can be curved toward the first end or the second end of the bracket 60. When the cylindrical first shell 11 is assembled and connected with the cylindrical bracket 60, the positioning structure 6341 provides positioning of the assembly angle between them. Fig.15 As shown, the positioning structure 6341 is used to provide positioning of the assembly angle when the wrapping element 16 and the bracket 60 are assembled and connected.

[0124] according to Figures 3 to 14 As shown, a second accommodating cavity 620 is arranged in the second supporting portion 62 of the bracket 60; the diameter of the second accommodating cavity 620 is smaller than the diameter of the first accommodating cavity 610, and an abutment step is defined therebetween; after assembly, the first liquid-conducting element 50 located in the first accommodating cavity 610 is supported and abutted against the abutment step.

[0125] In the embodiment, the second accommodating chamber 620 is used to at least partially accommodate the tubular element 14 and the atomizing assembly. The second accommodating chamber 620 is connected to the first accommodating chamber 610; during assembly, the tubular element 14 passes through the first accommodating chamber 610 and is inserted into the second accommodating chamber 620. In addition, the tubular element 14 and the bracket 60 are sealed by interference fit.

[0126] In an embodiment, the inner surface of the second accommodating cavity 620 is defined by a longitudinally extending groove 6210; on the one hand, during assembly, the exposed portion 310 of the second liquid-conducting element 30 is aligned with the groove 6210 to provide positioning during assembly; on the other hand, the exposed portion 310 of the second liquid-conducting element 30 extends into the groove 6210 to absorb the liquid matrix.

[0127] according to Fig.14 As shown in , the inner surface of the second accommodating chamber 620 may be arranged at an angle; for example, the inner diameter of at least part of the second accommodating chamber 620 may gradually increase in a direction close to the first accommodating chamber 610; then, when the tubular element 14 is inserted into the second accommodating chamber 620, the portion of the second accommodating chamber 620 with the increased inner diameter is opposite to the first perforation 141 of the tubular element 14, thereby forming a gap therebetween, and the gap is in liquid communication with the lower surface of the first liquid-conducting element 50. The gap is used to buffer the liquid matrix flowing out from the lower surface of the first liquid-conducting element 50. In use, after the liquid matrix in the liquid storage chamber 112 is absorbed through the upper surface of the first liquid-conducting element 50, a portion of it flows out into the gap through the lower surface, and finally passes through the first perforation 141 of the tubular element 14 and is absorbed by the second liquid-conducting element 30, as shown in FIG. Fig.14 In addition, the exposed portion 310 of the second liquid-conducting element 30 extending out of the second through hole 142 of the tubular element 14 abuts against the lower surface of the first liquid-conducting element 50 to directly absorb the liquid matrix, as shown in FIG. Fig.14 As shown by the arrow R1.

[0128] according to Figures 3 to 14 As shown, after assembly, a portion of the tubular element 14 extends into the bracket 60, and another portion extends from the first end of the bracket 60; for example, after assembly, the tubular element 14 has an exposed section extending outside the bracket 60 and / or the first liquid-conducting element 50, and forms a tight-fitting connection with the aerosol output tube 111 through the exposed section.

[0129] according to Figures 3 to 14 As shown, the third supporting portion 63 of the bracket 60 has a third accommodating cavity 631 opened toward the second end; the third accommodating cavity 631 is used to at least partially accommodate or install the wrapping element 16. A portion of the wrapping element 16 extends into the third accommodating cavity 631 through the opening of the third accommodating cavity 631 toward the second end. After assembly, a portion of the wrapping element 16 does not extend into the third accommodating cavity 631, and thus a portion of the wrapping element 16 is located outside the third supporting portion 63 and is clamped between the third supporting portion 63 of the bracket 60 and the control circuit board 18. An assembly groove 164 is also arranged on the outer surface of the wrapping element 16 for the extension arm 64 to pass through; after assembly, the extension arm 64 is at least partially accommodated in the assembly groove 164.

[0130] according to Fig.14 As shown, a sensing channel 162 is also arranged in the wrapping element 16; the sensing channel 162 provides a channel for connecting the first sensing surface of the airflow sensor 15 with the third accommodating cavity 631, thereby establishing a connection between the first sensing surface of the airflow sensor 15 and the airflow channel passing through the electronic atomization device 100.

[0131] In the embodiment, the third support portion 63 of the bracket 60 further has a wire fixing portion 633 extending toward the second end; the wrapping element 16 has an assembly hole 163 opposite to the wire fixing portion 633; ​​after assembly, the wire fixing portion 633 is inserted into the assembly hole 163. Furthermore, the wire fixing portion 633 is used to surround and limit the conductive pin 41 of the heating element 40; the conductive pin 41 of the heating element 40 at least partially passes through the wire fixing portion 633 from the second accommodating cavity 620 and is connected to the electrical contact 183 to form conduction.

[0132] according to Figures 3 to 14 As shown, the second supporting portion 62 of the bracket 60 is further provided with a plurality of flanges 621 circumferentially surrounding the second supporting portion 62 , and grooves 622 located between adjacent flanges 621 .

[0133] according to Figures 3 to 14 As shown, an air inlet channel is arranged on the bracket 60 to provide a channel path for the air from the air inlet 21 to enter the second accommodating cavity 620. The complete air inlet channel includes:

[0134] The first channel portion 624 extends from the third accommodating cavity 631 along the longitudinal direction of the bracket 60 or penetrates into the air inlet connecting groove 627 on the surface of the second supporting portion 62; the first channel portion 624 defines a first communication port 625 on the surface of the second supporting portion 62;

[0135] A second channel portion 628 extends from the second communication opening 626 on the surface of the second support portion 62 to or penetrates the second accommodation cavity 620;

[0136] The air intake communication groove 627 is used to connect the airflow of the first communication port 625 and the second communication port 626 .

[0137] In the embodiment, the air intake communication groove 627 is a groove arranged on the outer surface of the second support portion 62. Also, the air intake communication groove 627 circumferentially surrounds the second support portion 62. Also, the air intake communication groove 627 is close to or adjacent to the third support portion 63; specifically, the air intake communication groove 627 is formed or defined between the flange 621 closest to the third support portion 63 and the third support portion 63.

[0138] The airflow path through the electronic atomization device 100 during the puff is shown in Figures 3 to 14 As shown by the middle arrow R2, the external air entering from the air inlet 21 passes through the gap between the battery cell 70 and the outer shell 10, the first air hole 181 on the control circuit board 18 and the second air hole 161 on the wrapping element 16 in turn, and then enters the third accommodating chamber 631; then flows into the air inlet connecting groove 627 on the surface of the second support part 62 through the first channel part 624, and then flows to the second channel part 628 through the second connecting port 626; finally, it enters the tubular element 14 from the second channel part 628, and carries the aerosol generated by the atomization component to be delivered from the aerosol output tube 111 to the air outlet 113.

[0139] according to Fig.13 As shown in FIG, a tubular support element 162 is arranged in the second air hole 161 on the wrapping element 16 to provide support in the second air hole 161 to prevent the flexible wrapping element 16 from being squeezed during assembly, causing the second air hole 161 to be compressed and closed. The tubular support element 162 is rigid, such as a stainless steel tube or a ceramic tube.

[0140] according to Fig. 9 As shown, along the radial direction of the bracket 60, the first communication port 625 and the second communication port 626 are arranged opposite to each other; along the longitudinal direction of the bracket 60, the first communication port 625 and the second communication port 626 are at different longitudinal heights. Fig.10 In the embodiment, the first communication port 625 and the second communication port 626 are further away from the third supporting portion 63 .

[0141] Specifically according to Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, the flange 621 closest to the air intake communication groove 627 is an incomplete ring or circle in the circumferential direction, and the flange 621 closest to the air intake communication groove 627 has a side opening 6211 on one side of the first communication port 625. The air entering the first communication port 625 can enter the air intake communication groove 627 via the side opening 6211. And, the air entering the first communication port 625 can enter the groove 622 via the side opening 6211.

[0142] according to Figures 3 to 14 As shown, the support 60 further defines a ventilation channel 67 for providing a flow path for air to enter the liquid storage chamber 112, so that when the liquid matrix in the liquid storage chamber 112 is gradually consumed so that the negative pressure in the liquid storage chamber 112 exceeds a preset threshold, air can enter the liquid storage chamber 112 through the ventilation channel 67 to relieve or eliminate the negative pressure in the liquid storage chamber 112. Specifically, the ventilation channel 67 includes:

[0143] The vent hole 671 extends from the inner bottom wall of the first accommodating chamber 610 to the ventilation inlet 623;

[0144] The vent groove 672 extends from the inner bottom wall of the first accommodating cavity 610 through the inner side surface of the first accommodating cavity 610 to the first end of the bracket 60. Fig. 9 As shown, the vent hole 671 is arranged close to the inner surface of the first accommodating cavity 610 .

[0145] according to Fig. 9 and Fig.12 As shown by the middle arrow R3, when the negative pressure in the liquid storage chamber 112 exceeds a preset threshold, the air in the ventilation inlet 623 passes through the vent holes 671 and the vent grooves 672 in sequence and then enters the liquid storage chamber 112 to relieve the negative pressure in the liquid storage chamber 112.

[0146] In an embodiment, the vent hole 671 has a diameter of approximately 0.3-2.0 mm; and the vent groove 672 has a width and / or depth of approximately 0.3-2.0 mm.

[0147] In an embodiment, the area or size of the ventilation inlet 623 is larger than the area or size of the ventilation channel 67. Fig.12 As shown in , the ventilation inlet 623 has a width of about 4 to 8 mm and a height of 2 to 5 mm. Furthermore, in use, the cross-sectional area of ​​the ventilation inlet 623 is significantly enlarged compared to the ventilation channel 67, so that when the pressure in the liquid storage chamber 112 is greater than the external pressure, the ventilation inlet 623 can buffer or contain the liquid matrix that seeps out through the ventilation channel 67; when the pressure in the liquid storage chamber 112 is less than the external pressure, the liquid matrix buffered in the ventilation inlet 623 flows back into the liquid storage chamber 112 through the ventilation channel 67.

[0148] according to Fig. 9 , Fig.11 and Fig.12 As shown, the ventilation inlet 623 is surrounded and defined by the baffle walls 624 located on both sides of the ventilation inlet 623. Alternatively, the ventilation inlet 623 is surrounded and defined by two baffle walls 624 arranged opposite to each other. Figures 9 to 12 As shown in FIG. 6 , the retaining wall 624 is arranged obliquely.

[0149] according to Fig. 9 , Fig.11 and Fig.12 As shown, the ventilation inlet 623 is connected to the intake passage / first communication port 625 / second communication port 626 through a plurality of grooves 622 arranged on the outer surface of the second support portion 62, so that the air in the first communication port 625 / second communication port 626 / intake passage enters the ventilation passage.

[0150] In some embodiments, the ventilation inlet 623 is blocked and covered by the second sealing portion 82 of the sealing element 80 ; and the plurality of grooves 622 arranged on the outer surface of the second support portion 62 are also blocked and covered by the second sealing portion 82 of the sealing element 80 .

[0151] according to Fig. 9 , Fig.11 and Fig.12 As shown, a notch 629 is arranged on the flange 621; the adjacent grooves 622 are connected by airflow through the notch 629 of the flange 621 therebetween. Fig.11 and Fig.12 As shown by the arrow R4, the notches 629 on the adjacent flanges 621 are staggered in the longitudinal direction of the bracket 60, so that the air from the first connecting port 625 / the second connecting port 626 / the air intake passage flows through the plurality of grooves 622 in sequence along the circuitous path shown by the arrow R4 and then enters the ventilation inlet 623. Fig. 9 , Fig.11 and Fig.12 In the embodiment, the ventilation inlet 623 is connected to the groove 622 through the notch 629 on the closest flange 621. When the liquid matrix seeps out from the ventilation inlet 623, the liquid matrix will flow into and be retained in the groove 622, thereby preventing the liquid matrix seeping out from the ventilation channel 67 from leaking in the electronic atomization device 100.

[0152] Or in some more preferred embodiments, the notches 629 on adjacent flanges 621 are arranged opposite to each other in the radial direction of the bracket 60. Alternatively, the air path connecting the ventilation inlet 623 and the first communication port 625 extends in a circuitous manner in the groove 622 defined between the plurality of flanges 621; and the air path connecting the ventilation inlet 623 and the first communication port 625 extends in an arc of π in at least one groove 622.
