DETAILED DESCRIPTION

[0031] In order to have a clearer understanding of the technical features, purposes and effects of the present application, the specific implementation methods of the present application are now described in detail with reference to the accompanying drawings.

[0032] like Figure 1 and Figure 2 As shown, an electronic atomization device according to an embodiment of the present application may include a housing 1 , an atomization unit 10 disposed in the housing 1 , an air inlet channel 20 , and a bracket 30 .

[0033] In the housing 1, the air inlet channel 20 is connected to the atomizing channel 100 of the atomizing unit 10. After the external air enters the housing 1, it enters the atomizing channel of the atomizing unit 10 along the air inlet channel 20. After the atomizing unit 10 is started, the atomizing liquid is heated and atomized to form an aerosol. The bracket 30 is in the housing 1 and can support and position the atomizing unit 10 in the first end of the housing 1.

[0034] In some embodiments, in the height (or length) direction of the housing 1, the housing 1 has a first end and a second end opposite to each other. The atomization unit 10 is disposed in the first end of the housing 1, and an air outlet 101 is disposed on the first end of the housing 1. The atomization channel 100 of the atomization unit 10 is connected to the air outlet 101, and the aerosol formed by heating the atomization unit 10 is output through the air outlet 101 to be inhaled by the user. An air inlet 102 is disposed on the second end of the housing 1, and an air inlet channel 20 is disposed in the second end of the housing 1 and is connected to the air inlet 102, and external air enters the air inlet channel 20 through the air inlet 102.

[0035] It can be understood that the housing 1 as a whole can be, but is not limited to, a cylindrical shell, a flat shell, a polygonal shell, etc.

[0036] One side of the atomization unit 10 facing the second end of the housing 1 is an air inlet side, and the airflow from the air inlet channel 20 enters the atomization channel 100 of the atomization unit 10 from the air inlet side.

[0037] In some embodiments, the atomization unit 10 may further include an atomization housing 11 , an atomization tube 12 , an atomization assembly 13 , a liquid storage member 14 , and a partition 15 .

[0038] The atomizing housing 11 is fitted into the first end of the housing 1, the atomizing tube 12 is vertically arranged in the atomizing housing 11, and the internal channel of the atomizing tube 12 forms an atomizing channel 100. One end of the atomizing tube 12 is relatively connected to the air outlet 101, and the other end faces the second end of the housing 1 to be connected to the air inlet channel 20, so that the air outlet 101, the atomizing channel 100 and the air inlet channel 20 are connected in sequence.

[0039] The atomizing assembly 13 is arranged in the atomizing tube 12, and the liquid storage member 14 is arranged on the periphery of the atomizing tube 12 and contacts the atomizing assembly 13 to conduct liquid. The atomizing assembly 13 may further include a liquid guiding member and a heating member. In a selective embodiment, the liquid guiding member is a columnar liquid guiding member having a central through hole, and the heating member is a heating net embedded in the inner circumference of the liquid guiding member; a protrusion is provided on the columnar liquid guiding member to pass through the atomizing tube and contact the liquid storage member, and the atomized liquid on the liquid storage member can be adsorbed by the columnar liquid guiding member, and heated and atomized by the heating net to form an aerosol. In another selective embodiment, the liquid guiding member is arranged horizontally in the atomizing tube, and at least one end passes through the outside of the atomizing tube to contact the liquid storage member, and the heating member is a spiral heating wire wound on the outer circumference of the liquid guiding member, and the atomized liquid on the liquid storage member can be adsorbed by the liquid guiding member, and heated and atomized by the spiral heating wire to form an aerosol.

[0040] The partition 15 is fitted at the cup opening of the atomizing housing 11 toward the second end of the housing 1, closing the cup opening of the atomizing housing 11, and is also arranged between the first end and the second end of the housing 1; the partition 15 is also located at the air inlet side of the atomizing unit 10. The end of the atomizing tube 12 toward the second end of the housing 1 can be supported on the partition 15 by plugging or other means. Figure 2-Figure 4 As shown, a vent hole 150 is provided on the partition seat 15 at a position corresponding to the atomization tube 12 , and the vent hole 150 is connected to the atomization channel 100 and the air inlet channel 20 .

[0041] The spacer 15 is made of elastic insulating materials such as silicone, and the outer periphery of the spacer 15 is interference-fitted with the cup mouth of the atomizer housing 11 to form a sealed connection to avoid leakage caused by gaps. In addition, the spacer 15 can be a single-piece structure formed integrally, or can be formed by the cooperation of multiple seat bodies, which can be specifically set according to actual needs.

[0042] In some embodiments, the end of the atomizing housing 11 facing the air outlet 101 may be closed, or may be open and closed by a cover 16. Figure 2 The provision of the cover 16 facilitates the opening of the atomizing housing 11 , thereby facilitating the disassembly and assembly of the atomizing tube 12 , the atomizing assembly 13 and the liquid storage member 14 in the atomizing housing 11 .

[0043] In the housing 1 , the air inlet channel 20 is independently located in the second end of the housing 1 , that is, the air inlet channel 20 is isolated from (not connected to) the internal space of the second end. In addition, the air inlet channel 20 extends in the second end and connects and communicates between the air inlet 102 and the atomization channel 100 .

[0044] Combination Figures 2 to 5 In some embodiments, the bracket 30 includes a support portion 31 , in which a passage hole is provided. The passage hole penetrates opposite ends of the support portion 31 to form an air intake passage 20 .

[0045] In some embodiments, the bracket 30 further includes a supporting platform 32; the supporting platform 32 is laterally arranged and connected to one end of the pillar portion 31 facing the atomization unit 10, and is supported on the air inlet side of the atomization unit 10. The supporting platform 32 extends in the horizontal direction and is supported on the air inlet side of the atomization unit 10, specifically supporting a portion of the air inlet side (not the entire air inlet side), and another portion of the air inlet side of the atomization unit 10 is suspended in the housing 1.

[0046] The supporting platform 32 may further include a supporting portion 301 and a vacant portion 302. The supporting portion 301 is connected to one end of the pillar portion 31, and is used to support part of the atomization unit 10, that is, it is also the part that supports the air intake side of the atomization unit 10, and the inlet of the atomization channel 100 corresponds to the supporting portion 301. The vacant portion 302 is formed on one side of the supporting portion 301 so that the other part of the atomization unit 10 is suspended. Thus, since the pillar portion 31 provided with the air intake channel 20 forms part of the supporting platform 32, that is, the supporting portion 301, the atomization unit 10 can be supported; the vacant portion 302 may be formed on the other side of the supporting platform 32 to reduce the occupation of the internal space of the bracket 30, so as to leave more space for installing a battery assembly or a circuit board assembly with a larger capacity.

[0047] by Figure 2 Taking the placement direction shown as an example, the support column 31 and the supporting platform 32 are supported below the atomization unit 10 .

[0048] Specifically, the atomizing unit 10 is oriented and supported on the supporting platform 32 of the bracket 30 with its partition 15. The partition 15 cooperates with the bracket 30 to form a supporting matching assembly together with the bracket 30. In combination with the supporting platform 32 including a supporting portion 301 and a vacant portion 302, one end of the partition 15 is matched on the supporting portion 301, and the other end of the partition 15 is suspended in the vacant portion 302.

[0049] The supporting portion 301 of the supporting platform 32 may further be provided with a groove 320 surrounding the periphery of the air inlet channel 20, and the groove 320 connects the air inlet channel 20 and the atomization channel 100. The groove 320 is arranged to penetrate the bottom surface of one end of the air inlet channel 20, so as to be connected with the air inlet channel 20 and form the outlet of the air inlet channel 20. A slope 321 is arranged in the other end of the groove 320, and the lowest part of the slope 321 extends to one side of the outlet, so that the airflow enters the atomization channel 100 along the slope 321 after being output from the outlet. The setting of the slope 321 has a guiding effect on the airflow entering the atomization channel 100, and also has a buffering effect.

[0050] To improve the buffering effect of the airflow, in some embodiments, the bracket 30 further includes a concave-convex structure 322 for buffering the airflow, and the concave-convex structure 322 is disposed on the supporting platform 32. The concave-convex structure 322 is located in the flow direction of the airflow and on one side of the slope 321. Figure 4 and Figure 5 In the illustrated embodiment, the concave-convex structure 322 includes at least one raised portion and at least one recessed portion, and the raised portions and the recessed portions are arranged alternately. The airflow output from the air inlet channel 20 reaches the concave-convex structure 322 along the slope 321, and then enters the atomization channel 100 along the alternately arranged raised portions and recessed portions.

[0051] The arrangement of the above-mentioned slope 321 and the concave-convex structure 322 enables the airflow output from the air inlet channel 20 to turn along the slope 321, then move forward along the curve of the concave-convex structure 322, and enter the atomization channel 100 through the vent 150 on the partition 15. In this way, the direction of the airflow is effectively buffered compared to entering the atomization channel 100 in a straight line after being output from the air inlet channel 20, thereby ensuring the uniformity of the airflow and thereby improving the uniformity of the atomization effect.

[0052] In some embodiments, Figure 4-Figure 5 As shown, the bracket 30 also includes a first buckle portion 35, which is arranged at the vacant portion 302 and also corresponds to one side of the supporting portion 301, and is used to cooperate with the atomization unit 10 so that the atomization unit 10 is positioned on the supporting platform 32. In this regard, the atomization unit 10 suspended at one end of the vacant portion 302 may be provided with a second buckle portion 17 adapted to the first buckle portion 35, and is used to cooperate with the first buckle portion 35 in a snap-fit ​​manner. In combination with the atomization unit 10 being mainly supported on the supporting platform 32 by the spacer 15, the second buckle portion 17 is arranged on the bottom surface or side surface of the spacer 15 facing the first buckle portion 35.

[0053] Alternatively, the first buckle part 35 may include a protruding buckle, and the second buckle part 17 may include a buckle ring or a buckle groove. Alternatively, the first buckle part 35 may include a buckle ring, and the second buckle part 17 may include a protruding buckle. Alternatively, the first buckle part 35 may be a combination of a buckle and a buckle ring, and the second buckle part 17 may also be a combination of a buckle ring and a buckle.

[0054] The bracket 30 may further include a support frame 34 and at least one support plate 33 connected in a vertical direction. The support column 31 is formed on one side of the support frame 34, at least one side edge of the supporting platform 32 is connected to the connection between the support plate 33 and the support frame 34, and the first buckle portion 35 is connected to the connection between the support plate 33 and the support frame 34.

[0055] In the housing 1, the support frame 34 is supported and positioned in the second end of the housing 1, the support plate 33 is connected to the support frame 34 and can extend to fit in the first end of the housing 1, and the pillar portion 31 and the supporting platform 32 are connected between the support plate 33 and the support frame 34. In the second end of the housing 1, the support frame 24 is formed by connecting at least one strip and is mainly arranged near the inner wall surface of the housing 1 in the second end of the housing 1, so as to make room in the second end of the housing 1 to accommodate the power supply unit, etc., and also play a positioning role for the power supply unit to prevent the power supply unit from moving or shaking in the housing 1.

[0056] To achieve adjustable air flow into the air inlet channel 20 , in some embodiments, the electronic atomization device further includes an air inlet regulating component 40 for regulating the air inlet volume; the air inlet regulating component 40 is disposed in the second end of the housing 1 and is fitted between the air inlet 102 and the air inlet channel 20 .

[0057] Combination Figure 2 and Figures 7 and 8 In some embodiments, the air intake adjustment assembly 40 includes an adjustment member 41 and a docking member 42. The adjustment member 41 is matched at the air intake port 102, and the docking member 42 is arranged between the air intake passage 20 and the adjustment member 41. The adjustment member 41 is provided with a plurality of air intake holes 410, which are arranged at intervals and have different apertures; the air intake holes 410 have different apertures, and the amount of gas passing through is also different.

[0058] The docking member 42 is matched with the adjusting member 41, and a docking hole 420 communicating with the air inlet passage 20 is provided on the docking member 42. The adjusting member 41 can move back and forth relative to the docking member 42 in the arrangement direction of the air inlet holes 410, so that any air inlet hole 410 is relatively communicated with the docking hole 420, and then the air inlet 102 is connected with the air inlet passage 20 through any air inlet hole 410 and the docking hole 420.

[0059] The air inlet hole 410 may be, but is not limited to, a circular hole, a polygonal hole, or a combination of a circular hole and a polygonal hole. The number of the air inlet holes 410 is preferably two or more, and the two or more air inlet holes 410 are arranged on the adjusting member 41 according to a certain rule, for example, arranged from large to small according to the aperture, or arranged from large to small according to the aperture area, etc. When a larger flow of gas is required to enter the air inlet channel 20, the adjusting member 41 is moved so that the air inlet hole 410 with the largest (or larger) aperture on it reaches the position of the docking hole 420 on the docking member 42, and is directly connected with the docking hole 420. At this time, the air inlet 102 is connected with the air inlet channel 20 through the connected air inlet hole 410 and the docking hole 420. When a smaller flow of gas is required to enter the air inlet channel 20, similarly to the above operation, the air inlet hole 410 with the smallest (or smaller) aperture is driven to be directly connected with the docking hole 420.

[0060] The adjusting member 41 covers the air inlet 102 . By setting the sizes of the two, the adjusting member 41 always covers the air inlet 102 when it moves back and forth in the arrangement direction of the air inlet holes 410 . The air inlet 102 can only be connected to the air inlet channel 20 through the air inlet holes 410 .

[0061] In addition, the air intake volume is adjusted mainly by the user manually moving the adjusting member 41. For the convenience of operation, a protruding operating portion 43 is provided on the adjusting member 41. The operating portion 43 is located on the surface of the adjusting member 41 facing the air inlet 102, so that it can be exposed in the air inlet 102, which is convenient for the user to operate manually. The operating portion 43 can be a protruding structure of any shape, and an anti-slip structure, such as a concave-convex texture, etc., can also be provided thereon.

[0062] In some embodiments, Figure 1 and Figure 2 As shown, the electronic atomization device further includes a nozzle assembly 50; the nozzle assembly 50 is fitted on the first end of the housing 1 and is connected to the air outlet 101. The nozzle assembly 50 can be filled with a liquid absorbent, such as liquid absorbent cotton, to absorb droplets such as condensed liquid to prevent the user from sucking it out and leaking it.

[0063] In some embodiments, Figure 1 and Figure 2 As shown, the electronic atomization device further includes a power supply unit 60 and a control unit 70 disposed in the housing 1. The power supply unit 60 is used to supply power to the atomization unit 10; the control unit 70 is connected to the power supply unit 60 and the atomization unit 10 respectively, and can control the power supply unit 60 to supply power to the atomization unit 10. Figure 2 In the illustrated embodiment, the power supply unit 60 and the control unit 70 are both accommodated in the second end of the housing 1 .

[0064] The power supply unit 60 includes a battery assembly and the like.

[0065] The control unit 70 may include a control panel assembly and a switch. Alternatively, the switch may be a pneumatic switch, which is disposed in the housing 1 and in the airflow, for example, in the partition 15, between the atomization channel 100 and the air inlet channel 20. The pneumatic switch can be automatically started and stopped according to the airflow. For example, when the user performs a puffing action, the airflow enters from the air inlet and triggers the pneumatic switch, and then the control unit 70 controls the power supply unit 60 to supply power to the atomization unit 10, etc. Alternatively, the switch is a key switch, which is turned on and off by manual pressing.

[0066] Of course, the switch may also include push-button switches and pneumatic switches, with multiple options for opening and closing.

[0067] When the electronic atomization device of the present application is used, the user draws air through the nozzle assembly 50, and the airflow enters the air inlet channel 20 from the air inlet 102, and enters the atomization channel 100 along the air inlet channel 20. The airflow direction is as follows: Figure 2 As shown by the arrow in the middle, the atomizing unit 10 works after being powered on, and heats the atomized liquid adsorbed on the liquid guide member to form an aerosol, which is then output from the air outlet 101 along the atomizing channel 100 and inhaled by the user.

[0068] The above descriptions are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
