[0028] This application provides an electronic atomization device 300. Referring to FIG. 1 and FIG. 2, FIG. 1 is a schematic structural diagram of an electronic atomization device according to an embodiment of this application, and FIG. 2 is a schematic structural diagram of an atomizer of the electronic atomization device shown in FIG. 1.

[0029] The electronic atomization device 300 includes a host 200 and an atomizer 100. The host 200 is connected to the atomizer 100 to supply power to the atomizer 100, and the atomizer 100 is configured to store an aerosol substrate and atomize the aerosol substrate to generate an aerosol. The atomizer 100 may be detachably or non-detachably connected to the host 200.

[0030] In this embodiment, the host 200 may be detachably connected to the atomizer 100. The host 200 includes a battery and a control element. The control element is electrically connected to the battery and controls the battery to supply power to the atomizer 100.

[0031] Referring to FIG. 2 to FIG. 4, FIG. 3 is a schematic structural diagram of a cross-section of the atomizer shown in FIG. 2, which is taken along line CC, and FIG. 4 is a schematic structural diagram of a cross-section of the atomizer shown in FIG. 2, which is taken along line DD.

[0032] The atomizer 100 includes a housing 10, an atomization support 20, an atomization assembly 30, a bottom cover 40, and an electrode 50. The housing 10 accommodates the atomization support 20, and the atomization support 20 and an inner wall of the housing 10 cooperate to define a liquid storage cavity 12. The atomization assembly 30 is arranged on the atomization support 20 and cooperates with the atomization support 20 to define an atomization cavity 201. The bottom cover 40 covers an open end of the housing 10 and is connected to the atomization support 20. The electrode 50 is connected to the bottom cover 40 and electrically connected to the atomization assembly 30. The liquid storage cavity 12 is configured to store a liquid substrate and supply the liquid to the atomization assembly 30. The atomization assembly 30 is configured to atomize the liquid substrate to generate the aerosol in the atomization cavity 201. The electrode 50 is configured to electrically connect a control element in the host 200 to supply power to the atomization assembly 30.

[0033] The housing 10 includes a housing body 11 and an air duct tube 13. The air duct tube 13 is arranged in the housing body 11. The atomization support 20 is engaged with an inner wall surface of the housing body 11 to define the liquid storage cavity 12, and the air duct tube 13 is in communication with an air outlet 23 in the atomization support 20 to guide the aerosol in the atomization cavity 201 to a mouth of a user.

[0034] The atomization support 20 is accommodated in the housing 10. The atomization support 20 is provided with the air outlet 23, a mounting groove 24, and a liquid channel 25 that are sequentially arranged in a first direction A and are in communication with each other. The liquid channel 25 extends in a second direction B substantially perpendicular to the first direction A and penetrates to at least one side of the atomization support 20, and an orientation of a notch of the mounting groove 24 is substantially perpendicular to the first direction A.

[0035] In this embodiment, the atomization support 20 is a flexible support. A peripheral surface of the atomization support is engaged with and is in sealing fit with the inner wall surface of the housing body 11. An inner wall surface of the mounting groove 24 is engaged with the atomization assembly 30 to form a sealing fit. The atomization support 20 may also be in sealing fit with the bottom cover 40, to avoid liquid leakage. Relatively, the atomization support 20 is defined as the flexible support, so that at least three sealing members can be omitted, and there are few or even no positions at which the atomizer 100 needs to be sealed, thereby effectively reducing costs and simplifying the structure of the atomizer 100.

[0036] For example, the atomization support 20 is made of an elastic material such as a silica gel, rubber, or a thermoplastic elastomer (TPE).

[0037] Optionally, the atomization support 20 is a rigid support, and is engaged with an inner wall surface of the housing body 11 by a sealing member, to form a sealing structure for preventing liquid leakage.

[0038] As shown in FIG. 8, an inner wall of the mounting groove 24 includes a sealing surface 241, and the sealing surface 241 is configured to be in sealing engagement with an outer wall of the atomization assembly 30, so that the inner wall of the mounting groove 24 cooperates with the atomization assembly 30 to form an atomization cavity 201 isolated from the liquid channel 25.

[0039] When the atomization support 20 is a flexible support, a seal can be formed by causing a flexible inner wall of the mounting groove 24 to abut against the atomization assembly 30, and a surface of the flexible inner wall is a sealing surface 241. When the atomization support 20 is a rigid support, an elastic sealing member is arranged on the atomization assembly 30, and a rigid inner wall of the mounting groove 24 forms a seal with the elastic sealing member. A surface of the rigid inner wall is a sealing surface 241.

[0040] Referring to FIG. 3 to FIG. 8, FIG. 5 is a schematic structural front view of the atomizer shown in FIG. 2 with the housing removed, FIG. 6 is a schematic structural exploded view of the atomizer shown in FIG. 5, FIG. 7 is a schematic structural diagram of an atomization support of the atomizer shown in FIG. 5, and FIG. 8 is a schematic structural diagram of a cross-section of the atomization support shown in FIG. 7, which is taken along line EE.

[0041] The mounting groove 24 is located between the air outlet 23 and the liquid channel 25, and is in communication with the air outlet 23 and the liquid channel 25. The atomization assembly 30 is mounted in the mounting groove 24. A liquid absorbing surface 311 of the atomization assembly 30 faces the liquid channel 25, and an atomizing surface 312 of the atomization assembly 30 faces the air outlet 23. That is, the atomization assembly 30 may suck a liquid from a side in which the liquid channel 25 is located, and generate an aerosol to a side in which the air outlet 23 is located. The atomization cavity 201 is located in a side of the atomization assembly 30 facing the air outlet 23 and is isolated from the liquid channel 25. The air outlet 23 is in communication with the atomization cavity 201, so that the generated aerosol can directly reach the mouth of the user through the air outlet 23 and the air duct tube 13. An air duct through which the aerosol passes can directly lead to the mouth of the user without turning, and the air duct is smoother. This can effectively reduce the loss of the aerosol and increase an aerosol output. Compared with a path generated when the atomization cavity 201 is provided in the side facing away from the air outlet 23, a path generated by the air duct is shorter, the aerosol reaching the mouth has a higher temperature, and the aerosol amount is also larger, thereby improving the taste.

[0042] The first direction A and the second direction B are substantially perpendicular to each other. That is, the first direction A and the second direction B may be in a relationship of perpendicularity or approximately in a relationship of perpendicularity. A deviation between a right angle and an included angle between the first direction A and the second direction B can be allowed. For example, the deviation may be within a range from minus 5° to plus 5°.

[0043] The liquid channel 25 runs through at least one side of the atomization support 20 in the second direction B, and is in communication with the liquid storage cavity 12 through at least the penetrated side. In this embodiment, as shown in FIG. 3 and FIG. 8, the liquid channel 25 traverses the atomization support 20. That is, the liquid channel 25 runs through two sides of the atomization support 20 in the second direction B. Two ends of the liquid channel 25 are in communication with the liquid storage cavity 12, so as to improve an ability of timely liquid supply to the liquid channel 25, and discharge bubbles to the liquid storage cavity 12 through the liquid channel 25.

[0044] As shown in FIG. 3 and FIG. 6, the notch of the mounting groove 24 is configured to assemble the atomization assembly 30 into the mounting groove 24, and an orientation of the notch of the mounting groove 24 may be substantially parallel to the second direction B, or the orientation of the notch of the mounting groove 24 may be substantially perpendicular to the second direction B.

[0045] The orientation of the notch of the mounting groove 24 is substantially parallel to the second direction B, so that the atomization assembly 30 can be mounted into the mounting groove 24 according to the second direction B, and the notch of the mounting groove 24 and an opening of the liquid channel 25 are located in the same side surface of the atomization support 20. "Substantially parallel" may be understood as that the orientation of the notch of the mounting groove 24 and the second direction B may be in a parallel relationship or approximately in a parallel relationship, and a deviation angle can be allowed between the first direction A and the second direction B. For example, the deviation angle may be in the range from minus 5° to plus 5°.

[0046] Similarly, if the orientation of the notch of the mounting groove 24 is substantially perpendicular to the second direction B, the notch of the mounting groove 24 and the opening of the liquid channel 25 may alternatively be located in different side surfaces of the atomization support 20. That is, the notch of the mounting groove and the opening of the liquid channel may be in a relationship of perpendicularity, or may be approximately in a relationship of perpendicularity. Details are not described.

[0047] Distribution of the air outlet 23, the mounting groove 24, and the liquid channel 25 in the atomization support 20, the direction in which the liquid channel 25 extends, and the orientation of the notch of the mounting groove 24 are defined, to improve the structure of the atomization support 20 and reduce the structural complexity of the atomization support, thereby simplifying a process for forming the atomization support, and further simplifying a mold structure for manufacturing the atomization support 20 and reducing mold costs.

[0048] As shown in FIG. 7 and FIG. 8, the orientation of the notch of the mounting groove 24 is substantially parallel to the second direction B. The mounting groove 24 includes a guide inclined plane 240 starting from a side surface of the atomization support 20, and the guide inclined plane 240 is configured to guide the atomization assembly 30 into the mounting groove 24, so as to improve mounting convenience between the atomization assembly 30 and the mounting groove 24 and facilitate automated assembly of the atomizer 100; and / or the mounting groove 24 includes a positioning surface 242 opposite to the notch of the mounting groove, and the positioning surface 242 is configured to position the atomization assembly 30 in the mounting groove 24, so that the atomizing surface 312 of the atomization assembly 30 faces the air outlet 23.

[0049] As shown in FIG. 3 and FIG. 5 to FIG. 8, the atomization support 20 includes a first seat 21 and a second seat 22 that are arranged in the first direction A. The first seat 21 protrudes from the second seat 22, and the first seat 21 is provided with an air outlet 23, a mounting groove 24, and a liquid channel 25. That is, the air outlet 23, the mounting groove 24, and the liquid channel 25 are defined in the first seat 21. The liquid channel 25 runs through at least one side of the first seat 21 in the second direction B, and part of an outer surface of the first seat 21 and an inner wall surface of the housing 10 define a liquid discharging groove 202 in communication with the liquid channel 25. As shown in FIG. 3, the second seat 22 is engaged with the inner wall surface of the housing 10, and at least one side of the first seat 21 that is penetrated by the liquid channel 25 cooperates with the inner wall surface of the housing 10 to form a liquid discharging groove 202. The liquid channel 25 is in communication with the liquid discharging groove 202, and the liquid discharging groove 202 is further in communication with the liquid storage cavity 12.

[0050] Optionally, the liquid channel 25 may run through a side of the first seat 21, the penetrated side of the first seat 21 cooperates with the inner wall surface of the housing 10 to form a liquid discharging groove 202 in communication with the liquid storage cavity 12, and an end of the liquid channel 25 is in communication with the liquid discharging groove 202.

[0051] In this embodiment, as shown in FIG. 3 and FIG. 8, the liquid channel 25 traverses the first seat 21 in the second direction B, and two sides of the first seat 21 in the second direction B cooperate with the inner wall surface of the housing 10 to form two liquid discharging grooves 202. Two ends of the liquid channel 25 are in communication with the two liquid discharging grooves 202 respectively, so as to improve efficiency of supplying the liquid to the liquid channel 25 and the ability to discharge bubbles.

[0052] The liquid discharging groove 202 is formed by cooperation between the outer shape of the atomization support 20 and the inner wall surface of the housing 10. That is, there is no need to directly provide the liquid discharging groove 202 in the atomization support 20. This effectively reduces the structural complexity of the atomization support 20 and makes the atomization support easier to manufacture.

[0053] As shown in FIG. 5, specifically, a width of the first seat 21 in the second direction B is smaller than that of the second seat 22 in the same direction, and recesses 26 are formed in two sides of the first seat 21 in the second direction B relative to the second seat 22. Two ends of the liquid channel 25 are in communication with the two recesses 26 respectively. A sealing part 27 is annularly arranged on a periphery of the second seat 22, and the second seat 22 is in sealing engagement with the inner wall surface of the housing body 11 by the sealing part 27.

[0054] The first seat 21 and the second seat 22 are arranged in the first direction A, and the second seat 22 forms a sealing fit with the housing body 11. The sealing part 27 may be a sealing surface, a sealing rib, or the like. The inner wall surface of the housing body 11 surrounds a side of each recess 26 to define a liquid discharging groove 202, and the liquid channel 25 traverses the first seat 21 in the second direction B and is in communication with the recess 26. That is, the two ends of the liquid channel 25 are in communication with the two liquid discharging grooves 202 respectively.

[0055] The width of the first seat 21 in the second direction B is defined as being smaller than that of the second seat 22 in the same direction, to form the recesses 26 in the two sides of the first seat 21 in the second direction B relative to the second seat 22. The recesses 26 can form the liquid discharging grooves 202 through cooperation with the inner wall surface of the housing body 11, so that it is not necessary to directly provide a liquid discharging groove 202, a liquid discharging hole, or the like in the atomization support 20. The structure of the recess 26 is simple, which further reduces the complexity of the atomization support 20, further simplifies the mold structure for manufacturing the atomization support 20, and reduces mold costs.

[0056] Referring to FIG. 6 and FIG. 7, in this embodiment, the atomization support 20 is a flexible support. An end portion of the atomization support 20 provided with the air outlet 23 is provided with a groove 230. That is, the end portion of the first seat 21 that faces away from the second seat 22 is provided with the groove 230, and the groove 230 is provided around the air outlet 23. The atomizer 100 further includes a pressure plate 60, and the pressure plate 60 is accommodated in the groove 230. The pressure plate 60 is configured to improve a supporting strength of the end portion of the atomization support 20. In this embodiment, the pressure plate 60 supports the air duct tube 13 that abuts against the air outlet 23 and that is in the housing 10.

[0057] The pressure plate 60 is a hard and rigid plate. The pressure plate 60 is supported by the air duct tube 13, so that the supporting strength of the atomization support 20 can be increased, and the atomization support 20 can be prevented from being deformed due to an upward pushing force of the electrode 50 on the atomization assembly 30.

[0058] Further, an end of the second seat 22 that faces away from the air outlet 23 is sleeved on the bottom cover 40, and is hermetically combined with the bottom cover 40. The bottom cover 40 is provided with a liquid accumulation groove, and the second seat 22 covers the liquid accumulation groove. The liquid accumulation groove is configured to receive a leaked liquid to prevent the leaked liquid from leaking to the host 200, and the bottom cover 40 further covers the open end of the housing 10.

[0059] Referring to FIG. 3, FIG. 6, and FIG. 8, the second seat 22 is provided with an electrode hole 220, and the electrode hole 220 runs through the second seat 22 in the first direction A and is in communication with the liquid channel 25. The electrode 50 is connected to the bottom cover 40, and the electrode 50 is in interference fit with the electrode hole 220. The electrode 50 penetrates into the electrode hole 220, and at least a portion of the electrode 50 passes through the liquid channel 25 to be electrically connected to the atomization assembly 30.

[0060] Referring to FIG. 4, FIG. 8, and FIG. 9, an end of the atomization support 20 that faces away from the air outlet 23 is provided with at least one air inlet 28. That is, an end of the second seat 22 that faces away from the first seat 21 is provided with the at least one air inlet 28. An airflow channel 29 extending between the air inlet 28 and the mounting groove 24 is defined in the atomization support 20. That is, the airflow channel 29 is defined in the first seat 21. The airflow channel 29 avoids the liquid channel 25 and is in communication with the atomization cavity 201 to supply air into the atomization cavity 201.

[0061] In this embodiment, the second seat 22 is provided with two air inlets 28, which correspondingly bypass two sides of the liquid channel 25 to the mounting groove 24 through two airflow channels 29, to implement bilateral air supply to the atomization cavity 201. This provides better vaping experience for the user.

[0062] Optionally, an inner wall of a side of the liquid channel 25 is provided with an airflow channel 29 to implement unilateral air supply to the atomization cavity 201.

[0063] Referring to FIG. 3 and FIG. 10, in this embodiment, the atomization assembly 30 includes a heating member 32 and a capillary liquid guide member 31 for delivering the liquid substrate.
