DETAILED DESCRIPTION

[0030] 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.

[0031] like Figure 1 and Figure 2As 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 , and an air inlet passage 20 .

[0032] In the housing 1, the air inlet channel 20 is connected to the atomization channel 100 of the atomization unit 10. After the external air enters the housing 1, it enters the atomization channel of the atomization unit 10 along the air inlet channel 20; after the atomization unit 10 is started, the atomization liquid is heated and atomized to form an aerosol.

[0033] In some embodiments, the housing 1 has a first end and a second end opposite to each other in the height (or length) direction of the housing 1. The atomizing 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 atomizing channel 100 of the atomizing unit 10 is connected to the air outlet 101, and the aerosol formed by heating the atomizing 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.

[0034] 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.

[0035] In some embodiments, the atomization unit 10 may further include an atomization housing 11 , a ventilation tube 12 , an atomization assembly 13 , a liquid storage member 14 , and a partition 15 .

[0036] The atomizing housing 11 is fitted in the first end of the housing 1, the vent pipe 12 is vertically arranged in the atomizing housing 11, and the internal channel of the vent pipe 12 forms an atomizing channel 100. One end of the vent pipe 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.

[0037] The atomizing component 13 is arranged in the vent pipe 12, and the liquid storage component 14 is arranged on the periphery of the vent pipe 12 and contacts with the atomizing component 13 to conduct liquid. The atomizing component 13 may further include a liquid guiding component and a heating component. In a selective embodiment, the liquid guiding component is a columnar liquid guiding component with a central through hole, and the heating component is a heating net embedded in the inner circumference of the liquid guiding component; a protrusion is provided on the columnar liquid guiding component to pass through the vent pipe and contact the liquid storage component, and the atomized liquid on the liquid storage component can be adsorbed by the columnar liquid guiding component, and heated and atomized by the heating net to form an aerosol. In another selective embodiment, the liquid guiding component is horizontally arranged in the vent pipe, and at least one end passes through the outside of the vent pipe to contact the liquid storage component. The heating component is a spiral heating wire wound on the outer circumference of the liquid guiding component, and the atomized liquid on the liquid storage component can be adsorbed by the liquid guiding component, and heated and atomized by the spiral heating wire to form an aerosol.

[0038] The partition 15 is fitted at the opening of the atomizing housing 11 toward the second end of the housing 1 to close the opening of the atomizing housing 11 and is also arranged between the first end and the second end of the housing 1. The end of the vent pipe 12 toward the second end of the housing 1 can be supported on the partition 15 by plugging or the like. Figure 2-Figure 4 As shown, a vent hole 150 is provided on the partition seat 15 at a position corresponding to the vent pipe 12 , and the vent hole 150 is connected to the atomization channel 100 and the air inlet channel 20 .

[0039] 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 opening of the atomizing 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.

[0040] 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 vent pipe 12 , the atomizing assembly 13 and the liquid storage member 14 in the atomizing housing 11 .

[0041] 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, connecting and communicating between the air inlet 102 and the atomization channel 100. The independent setting of the air inlet channel 20 in the housing 1 can make all or most of the airflow entering the air inlet channel 20 flow to the atomization channel 100, avoiding or maximizing the loss of small airflow, thereby avoiding the loss of airflow that does not correspond to the power of the atomization unit 10, resulting in the problem of burnt taste or excessive atomization.

[0042] Combination Figures 2 to 5 In some embodiments, the electronic atomization device further includes a bracket 30. The bracket 30 includes a support portion 31, and the support portion 31 extends toward the first end along the air inlet 102 at the second end of the shell 1, so that the height direction (length extension direction) of the support portion 31 is consistent with the height direction (length extension direction) of the second end of the shell 1. A central through hole is provided on the support portion 31, and the central through hole runs through the entire support portion 31 to form an air inlet channel 20. The end surfaces of the opposite ends of the support portion 31 respectively form a first air vent and a second air vent, and the air inlet channel 20 connects the first air vent and the second air vent.

[0043] 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 support portion 31 facing the atomization unit 10 , and is supported below the atomization unit 10 .

[0044] Specifically, the atomizing unit 10 is oriented with its partition 15 toward and supported on the supporting platform 32 of the bracket 30. The supporting platform 32 may further be provided with a groove 320 surrounding the outer periphery of the air inlet channel 20; the groove 320 is directly opposite to the air inlet channel 20, and the bottom surface of the groove has a through portion, which is connected to the first vent to form the outlet of the air inlet channel 20. The second vent serves as the inlet of the air inlet channel 20, and the airflow enters the air inlet channel 20 from the inlet and then exits from the outlet.

[0045] Preferably, the outlet on the air inlet channel 20 is set to have an air flow rate that is consistent with the air flow rate of the inlet on the air inlet channel 20, so as to avoid or reduce air flow loss.

[0046] The bottom surface of the groove 320 also has an unpenetrated portion, in which a slope 321 is provided, and the lowest point 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.

[0047] In some embodiments, the supporting platform 32 and the pillar portion 31 may be formed integrally, or may be assembled as two independent components, so that the penetrating portion of the bottom surface of the groove 320 of the supporting platform 32 is connected to the first vent of the pillar portion 31 .

[0048] In order to improve the buffering effect of the airflow, in some embodiments, the supporting platform 32 is further provided with a concave-convex structure 322 for buffering the airflow; 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.

[0049] 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.

[0050] It is understandable that the support portion 31 and the supporting platform 32 thereon can be positioned at the second end of the housing 1 by cooperating with the inner wall of the housing 1. Figure 4In the illustrated embodiment, the bracket 30 may also include at least one support plate 33 and a support frame 34. The support frame 34 can be supported and positioned in the second end of the shell 1. The support plate 33 is connected to the support frame 34 and can extend to fit in the first end of the shell 1. The support column portion 31 and the supporting platform 32 are connected between the support plate 33 and the support frame 34.

[0051] In the second end of the shell 1, the support frame 24 is connected by at least one strip-shaped member and is arranged in the second end of the shell 1 mainly close to the inner wall surface of the shell 1 to make room in the second end of the shell 1 to accommodate the power supply unit 60, etc., and also plays a positioning role for the power supply unit 60 to prevent the power supply unit 60 from moving or shaking in the shell 1.

[0052] In some embodiments, reference Figure 2 , the air inlet channel 20 can also be formed by an air inlet pipe (not shown). In one embodiment, the air inlet pipe is independently arranged in the second end of the shell 1 relative to the shell 1, and the air inlet pipe is a tube body with both ends open, and its internal channel forms the air inlet channel 20; one end of the air inlet pipe serves as an outlet and is connected to the atomization channel 100, and the other end of the air inlet pipe serves as an inlet and is connected to the air inlet 102 on the shell 1. In another embodiment, the air inlet pipe is formed integrally on the inner wall of the shell 1, and can be formed by integral injection molding with the shell 1, or extended from the inner wall of the shell 1.

[0053] 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 .

[0054] Combined with the independent setting of the air intake channel 20 in the housing 1, the air intake regulating component 40 adjusts the air flow entering the air intake channel 20, so that the air flow entering the atomizing channel 100 from the air intake channel 20 is consistent with the air flow corresponding to the power of the atomizing unit 10, thereby meeting the required atomization effect. Figure 2 and Figure 6-Figure 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.

[0055] 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.

[0056] The air inlet through 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 through holes 410 is preferably two or more, and the two or more air inlet through 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 passage 20, the adjusting member 41 is moved so that the air inlet through 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 passage 20 through the connected air inlet through hole 410 and the docking hole 420. When a smaller flow of gas is required to enter the air inlet passage 20, similarly to the above operation, the air inlet through hole 410 with the smallest (or smaller) aperture is driven to be directly connected with the docking hole 420.

[0057] Alternatively, the adjusting member 41 may specifically include a movable plate 411 covering the air inlet 102, and two side plates 412 connected to opposite sides of the movable plate 411. The air inlet holes 410 are mainly provided on the movable plate 411, the outer circumference of the movable plate 411 is larger than the inner circumference of the air inlet 102, and when the adjusting member 41 moves back and forth in the arrangement direction of the air inlet holes 410, the movable plate 411 always covers the air inlet 102, and the air inlet 102 can only communicate with the air inlet passage 20 through the air inlet holes 410. The two side plates 412 define a guide rail 400 on the movable plate 411, and the docking member 42 can be movably fitted in the guide rail 400.

[0058] According to the moving position of the docking member 42 on the movable plate 411, a plurality of air intake holes 410 are arranged on one end of the movable plate 411, and a limiting portion 413 is provided at the other end of the movable plate 411 for limiting the moving stroke of the docking member 42 to prevent the docking member 42 from moving too much and causing the docking holes 420 to be out of the arrangement range of the air intake holes 410.

[0059] 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.

[0060] 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.

[0061] 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 .

[0062] The control unit 70 may include a control panel 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 automatically start and stop according to the airflow. For example, when the user performs a suction 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.

[0063] Of course, the switch may also include push-button switches and pneumatic switches, with multiple options for opening and closing.

[0064] 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.

[0065] 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.
