After the element or device is fixed or restricted to the specific position or place, it can be disassembled or cannot be disassembled, which is not limited in the embodiments of the present application.

[0038] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0039] An embodiment of the present application provides an atomizer 100 for atomizing a liquid matrix to generate an aerosol, such as Figure 1 As shown, the atomizer 100 includes a main housing 10 and a base 20. The main housing 10 has a first end 11 and a second end 12 that are oppositely arranged along the length direction of the atomizer 100. An air outlet 111 for the aerosol to escape from the atomizer 100 is provided at the first end 11, and the second end 12 is open. The base 20 extends into the main housing 10 from the open end of the second end 12 to provide support for other components in the main housing 10.

[0040] As Figure 2 shown, a liquid storage cavity 13 is provided in the main housing 10. The liquid storage cavity 13 is used to store the atomizable liquid matrix. When the liquid stored in the liquid storage cavity 13 is a medicinal liquid, the atomizer 100 can be used as a medical atomizer for treating respiratory diseases; when the liquid stored in the liquid storage cavity 13 is an e-cigarette atomization liquid, the atomizer 100 can be used as an e-cigarette.

[0041] Please continue to refer to Figure 2 , a bracket 30 is provided in the main housing 10. The bracket 30 is fixedly connected to the base 20. A holding chamber 31 is defined in the bracket 30. A longitudinally extending tubular body 40 is provided in the holding chamber 31, and an atomization assembly 50 is provided in the tubular body 40. The bracket 30 is provided with a plurality of liquid guiding grooves 31 that communicate with the liquid storage cavity 13 and extend along the longitudinal direction of the bracket 30. At the same time, liquid guiding holes (not shown in the figure) are provided on the tube wall of the tubular body 40. The liquid matrix in the liquid storage cavity 13 can flow to the atomization assembly 50 through the liquid guiding grooves 31 and the liquid guiding holes, and the atomization assembly 50 then atomizes the liquid matrix to generate an aerosol.

[0042] As Figure 3As shown, the atomization component 50 includes a first liquid guiding element 51 and a heating element 52 coupled to the first liquid guiding element 51. The first liquid guiding element 51 is formed with a through hole 511 longitudinally penetrating the first liquid guiding element 51, such that the first liquid guiding element 51 has an outer surface 512 and an inner surface 513, and the heating element 52 is coupled to the inner surface 513. The liquid matrix flows through the liquid guiding groove 31 and the liquid guiding hole to the outer surface 512 of the first liquid guiding element 51. The first liquid guiding element 51 then absorbs the liquid matrix and transfers the liquid matrix to the heating element 52 on the inner surface 513. The heating element 52 can then heat and atomize the liquid matrix to generate an aerosol, and release the aerosol into the through hole 511. That is to say, the through hole 511 is the atomization chamber of the atomizer 100.

[0043] And, as Figure 2 shown, to reduce the leakage probability of the liquid matrix on the first liquid guiding element 51, the atomizer 100 further includes a second liquid guiding element 60 surrounding the first liquid guiding element 51. The first liquid guiding element 51 and the second liquid guiding element 60 are in contact. The liquid guiding groove 31 communicates with the liquid storage chamber 13 and the second liquid guiding element 60. The liquid matrix in the liquid storage chamber 13 first flows through the liquid guiding groove 31 to the second liquid guiding element 60. The second liquid guiding element 60 absorbs the liquid matrix and then transfers it to the first liquid guiding element 51, and then is transferred by the first liquid guiding element 51 to the heating element 52, as shown in the flow path R1 of the liquid matrix shown in Figure 2 shown.

[0044] The first liquid guiding element 51 and the second liquid guiding element 60 are made of capillary core materials, such as any one of cotton fiber, non-woven fabric, glass fiber rope, etc., or a porous ceramic body with a microporous structure. After the first liquid guiding element 51 and the second liquid guiding element 60 absorb the liquid matrix, they can transfer the liquid matrix through the internal voids or microporous structures. The heating element 52 is preferably configured in a mesh shape to improve the heating efficiency, and can then be adapted to the shape of the through hole 511 for coupling to the inner surface 513 of the first liquid guiding element 51. For example Figure 3 in some examples shown, the first liquid guiding element 51 is formed by laminating multiple layers of fiber sheets and wound around the periphery of the heating element 52.

[0045] As Figure 2As shown, the main housing 10 further includes an air duct 14 extending in the liquid storage cavity 13. One end of the air duct 14 communicates with the air outlet 111, and the other end extends into the tubular body 40. Thus, the aerosol in the through hole 511 can enter the air duct 14 along the tubular body 40, and further the air duct 14 transports the aerosol to the air outlet 111. Meanwhile, an air inlet 24 for external air to enter the atomizer 100 is provided on the base 20. When the user sucks at the air outlet 111, a negative pressure is generated inside the atomizer 100, prompting the external air to enter the atomizer 100 through the air inlet 24, enter the atomization chamber (through hole 511) along the internal air inlet passage, then flow into the air duct 14, and finally be transported to the air outlet 111 by the air duct 14. The user can inhale the aerosol by sucking at the air outlet 111, as shown in Figure 2 the transmission path R2 of the aerosol in

[0046] Please continue to refer to Figure 2 . An electrode hole is provided on the base 20, and a conductive electrode 21 is provided in the electrode hole. The conductive electrode 21 is used to electrically connect an external power supply component and the heating element 52. The conductive electrode 21 conducts the electric energy of the external power supply component to the heating element 52, and the heating element 52 can then heat and atomize the liquid matrix.

[0047] As Figure 2 , Figure 4 and Figure 5 shown, the bracket 30 includes a first part 32 and a second part 33 distributed in the longitudinal direction. The outer diameter of the first part 32 is larger than that of the second part 33. The first part 32 is close to the liquid storage cavity 13, while the second part 33 is far from the liquid storage cavity 13, that is, the first part 32 is located above the second part 33. The base 20 includes a bottom wall 22 and a side wall 23 extending from the bottom wall 22 towards the liquid storage cavity 13. The side wall 23 is fixedly connected to the first part 32, so that a receiving cavity 331 is defined between the side wall 23 and the second part 33.

[0048] Specifically, as Figure 4 and Figure 5 shown, a buckle 323 is provided on the first part 32 of the bracket 30, and a slot 231 adapted to the buckle 323 is provided on the side wall 23 of the base 20. The buckle 323 and the slot 231 are snap-connected to fixedly connect the base 20 and the bracket 30. It is easy to understand that in some embodiments, a slot can also be provided on the first part 32 and a corresponding buckle can be provided on the side wall 23 to realize the fixed connection between the base 20 and the bracket 30.

[0049] Further, an air passage is provided on the first portion 32. The air passage is used to guide external air into the liquid storage chamber 13 to supplement air to the liquid storage chamber 13. When the atomizer 100 operates, as the liquid matrix in the liquid storage chamber 13 is consumed, the volume in the liquid storage chamber 13 increases, which in turn causes the air pressure in the liquid storage chamber 13 to decrease and generate a negative pressure. Under the action of the negative pressure, the liquid matrix in the liquid storage chamber 13 cannot flow smoothly to the atomizing assembly 50, easily causing the atomizing assembly 50 to dry burn due to insufficient liquid supply. By providing the air passage, air can be supplemented to the liquid storage chamber 13, thereby maintaining the air pressure balance in the liquid storage chamber 13 and enabling the liquid matrix to continue to flow smoothly into the atomizing assembly 50.

[0050] The accommodation chamber 331 communicates with the air passage. Since the side wall 23 of the base 20 is connected to the first portion 32 of the bracket 30, the accommodation chamber 331 defined by the side wall 23 and the second portion 32 will have a relatively large storage space, and the accommodation chamber 331 can collect more liquid matrix leaking from the liquid storage chamber 13 through the air passage.

[0051] In this embodiment, by arranging the atomizing assembly 50 in the bracket 30, the contact area between the atomizing assembly 50 and the liquid matrix can be reduced. At the same time, a relatively large accommodation chamber 331 is defined by the side wall 23 of the base 20 and the second portion 32 to collect the liquid matrix leaking from the air passage, thereby reducing the overall probability of liquid matrix leakage.

[0052] Moreover, at least a part of the second liquid guiding element 60 is located in the second portion 32. Since the second portion 32 has a relatively small outer diameter, at least a part of the second portion 32 can be appropriately compressed between the inner wall of the second portion 32 and the atomizing assembly 50, which is beneficial for controlling the penetration speed of the liquid matrix and reducing the leakage of the liquid matrix.

[0053] In some embodiments, as Figure 6 shown, the inner wall of the liquid guiding groove 31 includes a first section 311 extending longitudinally and a second section 312 extending obliquely from the first section 311. The liquid matrix in the liquid storage chamber 13 flows through the first section 311 and the second section 312 in sequence to the second liquid guiding element 60. By providing the inclined second section 312, when the remaining liquid matrix in the liquid storage chamber 13 is less, the remaining liquid matrix can be completely guided to the second liquid guiding element 60, and then transmitted by the second liquid guiding element 60 to the atomizing assembly 50 for atomization, improving the utilization rate of the liquid matrix.

[0054] In some embodiments, as Figure 2 and Figure 6As shown, the atomizer 100 further includes a first seal 70 for sealing the liquid storage chamber 13. The first seal 70 is provided with an annular groove 71, and a part of the tubular body 40 is inserted into the annular groove 71. A liquid guiding hole (not shown in the figure) for the liquid matrix to flow through is formed on the first seal 70, and the liquid matrix flows into the liquid guiding groove 31 through the liquid guiding hole. The first seal 70 is sleeved on the first part 32 of the bracket 30, and the first seal 70 elastically abuts against the inner wall of the main housing 10 to seal the liquid storage chamber 13, so that the liquid matrix flows along a preset path and avoids leakage of the liquid matrix through the assembly gap between the bracket 30 and the inner wall of the main housing 10.

[0055] The first part 32 includes an extension portion 321 extending towards the liquid storage chamber 13. The extension portion 321 passes through the first seal 70 and extends into the liquid storage chamber 13. The air passage as described above is defined between the extension portion 321 and the first seal 70 to guide external air into the liquid storage chamber 13.

[0056] Specifically, as Figure 6 and Figure 8 shown, a longitudinally extending first groove 3211 is formed on the outer surface of the extension portion 321. When the extension portion 321 passes through the first seal 70, the first seal 70 and the first groove 3211 can define the air passage as described above. It is easy to understand that in some embodiments, the first groove 3211 can also be provided on the first seal 70, and then the air passage as described above is defined by the surface of the extension portion 321 and the first groove 3211.

[0057] In some embodiments, as Figure 2 shown, the atomizer 100 further includes a second seal 80 for sealing the receiving chamber 331. The atomization assembly 50 is supported on the second seal 80, and the second seal 80 elastically abuts against the inner wall of the main housing 10 to seal the receiving chamber 331. The first seal 70 and the second seal 80 can be any one of silica gel, rubber, latex, etc., and sealing can be achieved by elastically abutting against the inner wall of the main housing 10.

[0058] Further in some embodiments, as Figure 2 and Figure 7 shown, the second seal 80 has a second groove 81, and a part of the second part 33 is press-fitted and inserted into the second groove 81 to provide support for the bracket 30, so that the bracket 30 is more firmly fixed in the main housing 10.

[0059] And, in some embodiments, as Figure 2 and Figure 7As shown, a longitudinally extending third groove 82 is formed on the outer surface of the second seal 80. The third groove 82 and the side wall 23 of the base 20 define an air flow channel, which communicates with the accommodation chamber 331 to guide external air into the accommodation chamber 331. Since the accommodation chamber 331 communicates with the above-mentioned air channel, the external air can further flow into the liquid storage chamber 13 through the accommodation chamber 331 and the above-mentioned air channel to replenish air to the liquid storage chamber 13.

[0060] In some embodiments, as Figure 2 and Figure 4 shown, a flange 322 is formed on the side surface of the first part 32. When the first seal 70 is sleeved on the first part 32, the flange 322 provides support for the first seal 70, thereby improving the sealing effect of the first seal 70.

[0061] An embodiment of the present application further provides an electronic atomization device, which can be seen in Figure 9 shown, including an atomizer 100 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply component 200 that powers the atomizer 100.

[0062] In an alternative embodiment, such as Figure 9 shown, the power supply component 200 includes a receiving cavity 270 provided at one end along the length direction for receiving and accommodating at least a part of the atomizer 100, and electrical contacts 230 at least partially exposed on the surface of the receiving cavity 270 for forming an electrical connection with the atomizer 100 and powering the atomizer 100 when at least a part of the atomizer 100 is received and accommodated within the power supply component 200.

[0063] According to Figure 9 the preferred embodiment shown, a conductive electrode 21 is provided at the end of the atomizer 100 opposite to the power supply component 200 along the length direction. When at least a part of the atomizer 100 is received in the receiving cavity 270, the conductive electrode 21 forms conduction by contacting and abutting against the electrical contact 230.

[0064] A seal 260 is provided inside the power supply component 200, and at least a part of the internal space of the power supply component 200 is separated by the seal 260 to form the above-mentioned receiving cavity 270. In Figure 9 the preferred embodiment shown, the seal 260 is configured to extend along the cross-sectional direction of the power supply component 200, and is preferably made of a flexible material such as silica gel, thereby preventing the liquid matrix that seeps from the atomizer 100 into the receiving cavity 270 from flowing to components such as the controller 220 and the sensor 250 inside the power supply component 200.

[0065] In Figure 9In the preferred embodiment shown, the power supply assembly 200 also includes a battery cell 210 for power supply at the other end away from the receiving cavity 270 along the length direction; and a controller 220 arranged between the battery cell 210 and the receiving cavity 270, which can be operated to guide current between the battery cell 210 and the electrical contact 230.

[0066] During use, the power supply assembly 200 includes a sensor 250 for sensing the suction airflow generated when suction is performed through the atomizer 100 , and then the controller 220 controls the battery cell 210 to output current to the atomizer 100 / 100a according to the detection signal of the sensor 250 .

[0067] Further in Figure 9 In the preferred embodiment shown, the power source assembly 200 is provided with a charging interface 240 at the other end away from the receiving cavity 270 for charging the battery cell 210 .

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Under the concept of the present application, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes in different aspects of the present application as described above, which are not provided in detail for the sake of simplicity. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
