The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

Fig. 1 and 2 illustrate an electronic atomizing device according to some embodiments of the present utility model, which may have a hand-held rod-like structure for a user to inhale aerosol. As shown, the electronic atomizer device may include an atomizer 1 and a power supply device 2 coupled to the atomizer 1. The atomizer 1 may be used for storing and heating an aerosol-generating substrate in a liquid state, such as a medical liquid, and for delivering the aerosol. The power supply device 2 may be used to supply power to the atomizer 1. In some embodiments, the atomizer 1 and the power supply 2 may each have a substantially elliptical cylindrical shape and are mechanically and electrically connected together in an axial direction. In some embodiments, the atomizer 1 and the power supply device 2 may be detachably connected together by magnetic attraction. It will be appreciated that the atomizer 1 and the power supply means 2 are not limited to being in the shape of an elliptic cylinder, but may be in the shape of a cylinder having a circular, racetrack or irregular cross section, or in the shape of a non-cylinder.

As shown in fig. 3-7, the atomizer 1 may in some embodiments comprise an atomizer body 100 and a housing 20 that is sleeved on the atomizer body 100 along a longitudinal axis X, with a liquid storage space 70 formed between the atomizer body 100 and the housing 20. The liquid storage space 70 is used for containing a liquid aerosol-generating substrate, the atomizing body 100 is used for heating the liquid aerosol-generating substrate in the liquid storage space 70 to generate aerosol and mixing the aerosol with ambient air, and the shell 20 is used for guiding out the mixture of aerosol and air and protecting the atomizing body 100.

Housing 20 may include an elongated flat housing 21 and an airway tube 22 in some embodiments. The elongated flat housing 21 has an opening 212 at one end (lower end) and an air outlet 210 at the other end (upper end). One end of the air guide pipe 22 is communicated with the air outlet hole 210, and the other end extends towards the opening 212 of the casing 21. The air duct 22 may be integrally formed with the housing 21 in some embodiments, and its distal end is inserted into the atomizing body 100 to conduct out mist generated during operation of the atomizing body 100. It is to be understood that the shape of the housing 21 is not limited to the illustrated shape, and other shapes such as a square cylinder shape and a cylindrical shape may be applied.

The end of the housing 21 where the air outlet holes 210 are provided may be flattened in some embodiments to form a suction nozzle. The atomizing body 100 is plugged into the housing 20 through the opening 212 in the longitudinal direction, and the opening 212 is blocked, so that the liquid storage space 70 is sealed. The inner sides of the two ends of the perforated end of the housing 21 are respectively provided with a clamping groove 216 to be buckled with the atomization main body 100 plugged into the housing 21, so as to prevent the atomization main body 100 from falling off from the housing 20.

As further shown in fig. 3-7, the housing 21 may in some embodiments include a first sidewall 211, a second sidewall 213, a third sidewall 215, and a fourth sidewall 217 that are connected in series in the circumferential direction.

The second sidewall 213 and the fourth sidewall 217 may be curved in some embodiments and are located at opposite ends of the long axis of the cross section of the housing 21, respectively, and have a larger curvature.

Referring to fig. 8 together, the atomizing body 100 may include a cylindrical atomizing base 10, an atomizing assembly 30 disposed on one side of the atomizing base 10, a fastening member 40 for fastening the atomizing assembly 30 to the atomizing base 10, a first sealing member 50 disposed on an upper portion of the atomizing base 10, and a second sealing member 60 disposed on the other side of the atomizing base 10 in some embodiments. The atomizing base 10 serves to form a skeleton of the atomizing body 100, and to form an air flow channel Q extending along the longitudinal axis X of the atomizer 1, and a conductive channel. The atomizing assembly 30 is used for heating and atomizing the liquid in the liquid storage space 70 and releasing the mist into the atomizing base 10. The first seal 50 serves to seal a gap between the upper portion of the atomizing base 10 and the gas guide pipe 22, and also serves to form a ventilation passage together with the atomizing base 10. The second seal 60 is used to seal the relief aperture 1250 in the sidewall of the atomizing base 10.

The atomizing base 10 may in some embodiments comprise a base 11, a cylindrical atomizing chamber 12 disposed longitudinally on top of the base 11, and a cylindrical connecting chamber 13 disposed on top of the atomizing chamber 12. The base 11 may be used in some embodiments to block the opening 212 of the housing 20, provide electrical connection for the atomizing assembly 30, and to direct ambient air into the atomizing chamber 12. The atomizing chamber 12 may, in some embodiments, form an atomizing chamber 120 and may have an atomizing assembly 30 mounted thereon in communication with the atomizing chamber 120. The connecting chamber 13 may be used in some embodiments to communicate the nebulizing chamber 120 with the airway tube 22 of the housing 20, to partition the reservoir space 70, and to ventilate the reservoir space 70.

Referring to fig. 9 together, the base 11 may in some embodiments include a base body 111 having a substantially elliptical cross-section, a sealing ring 112 sleeved on the base body 111, and a pair of electrodes 113 integrally formed in the base body 111. The base body 111 and the sealing ring 112 are used for sealing the opening 212 of the housing 20, and the pair of electrodes 113 are used for electrically connecting the atomizing assembly 30 with the positive and negative electrodes of the power supply device 2 respectively. In some embodiments, the base body 111 is integrally injection molded.

Referring to fig. 11 together, the electrode 113 may be made of an elastic conductive material such as a metal sheet, and may include a U-shaped first conductive end 1131 fixed in the base body 111 and having a middle portion exposed to the bottom surface of the base body 111, and a second conductive end 1132 connected to the first conductive end 1131 and protruding from the top surface of the base body 111 and inclined to one side, where the first conductive end 1131 is electrically connected to the power device 2, and the second conductive end 1132 is elastically pressed against the atomizing assembly 30.

As further shown in fig. 9, the base 11 may further include an air inlet channel 114 penetrating the base body 111, a flow guiding structure 115 disposed on the top surface of the base body 111 and near the air outlet of the air inlet channel 114, and a pair of latch arms 116 disposed at two opposite ends of the top surface of the base body 111. The air inlet channel 114 is configured to provide ambient air into the atomizing chamber 120 and the flow directing structure 115 is configured to direct the air flow to the atomizing assembly 30. The pair of latching arms 116 are configured to engage with two latching grooves 216 of the housing 21, respectively. The direction of extension of the air inlet channel 114 may in some embodiments be parallel to the longitudinal axis X of the atomizer 1.

The intake passage 114 may be rectangular in cross-section in some embodiments, forming an elongated slot. The air intake passage 114 may, in some embodiments, include an air intake section 1141 located at a lower portion and extending longitudinally, an air outlet section 1143 located at an upper portion and extending longitudinally, and a transition section 1142 connecting the air intake section 1141 and the air outlet section 1143. Preferably, the two walls of the air inlet section 1141, the transition section 1142 and the air outlet section 1143 in the width direction and one wall in the thickness direction are flush to facilitate demolding in the integral injection molding process.

In some embodiments, the inlet section 1141 and the outlet section 1143 may each have a rectangular parallelepiped shape, and the transition section 1142 may have a wedge shape. The thickness of the air inlet section 1141 is greater than that of the air outlet section 1143, so that the cross-sectional area of the air inlet section 1141 is greater than that of the air outlet section 1143, so that the sucked air is accelerated when flowing out from the air outlet section 1143, and can be better blown to the atomizing assembly 30.

In some embodiments, the air inlet 114 is configured in a stepped shape as described above, and the length of the air outlet segment 1143 is preferably one fifth to one third of the entire length of the air inlet 114, which may also facilitate the formation of the air inlet 114. Because the thickness of the entire air inlet channel 114 is as thin as the air outlet section 1143 during the integral molding of the base body 111, the mold for molding the air inlet channel 114 will be thin and long. In the molding process such as integral injection molding, the mold is easily deformed or broken after being pressed, and thus the qualified intake passage 114 cannot be formed. The mold for forming the air inlet channel 114 has a smaller thickness than the portion corresponding to the air outlet section 1143, and the length of the portion is one fifth to one third of the length of the entire mold, and the other portions are relatively thicker, so that the deformation resistance of the entire mold can be greatly improved, and the reliability of the mold is ensured while the narrow air passage is ensured.

The flow directing structure 115 may in some embodiments include a flow directing surface 1151 directly above the air outlet of the air outlet section 1143, the flow directing surface 1151 may be a plane inclined toward the atomizing assembly 30. It is understood that the cross section of the air intake passage 114 is not limited to rectangle, but may be a longitudinal slit such as a longitudinal racetrack, a longitudinal ellipse, or a cylindrical slit such as a circle or a square.

As further shown in fig. 3 and 4, the atomizing chamber 12 may be cylindrical in some embodiments, and may be integrally formed on the top surface of the base body 111 in the longitudinal direction. The atomizing chamber 12 in some embodiments may include a first sidewall 121, a second sidewall 123, a third sidewall 125, and a fourth sidewall 127 that are sequentially connected in a circumferential direction, which together define a substantially rectangular parallelepiped atomizing chamber 120. The first, second and fourth side walls 121, 123, 127 of the nebulization chamber 12 are opposite the first, second and fourth side walls 211, 213, 217, respectively, of the housing 21 and are each formed with gaps, which in some embodiments communicate with each other. The first, second, and fourth sidewalls 121, 123, 127 may each include a flat outer surface in some embodiments.

The outer wall surface of the third side wall 125 of the atomizing chamber 12 may be closely attached to the inner wall surface of the third side wall 215 of the housing 21 of the housing 20, and a relief hole 1250 (as shown in fig. 10) penetrating in the thickness direction is formed therein. The relief hole 1250 is used to facilitate the formation of the atomizing base 10, and the second seal 60 is sealed in the relief hole 1250 to prevent leakage of the liquid into the atomizing chamber 120. In some embodiments, the outer wall surface of the third sidewall 125 may be curved to better fit against the inner wall surface of the third sidewall 215 of the housing 21.

As shown in fig. 8 and 9, the first side wall 121 of the atomizing chamber 12 may, in some embodiments, include a mounting portion 1210 for receiving the atomizing assembly 30 and a bore 1212 for communicating the mounting portion 1210 with the atomizing chamber 120, and the mounting portion 1210 may, in some embodiments, be a recess for receiving the atomizing assembly 30. The mounting portion 1210 may be recessed from an outer surface of the first sidewall 121 in a direction away from the first sidewall 211 of the housing 21 in some embodiments. The perforation 1212 may be formed in the middle of the groove bottom of the mounting portion 1210 in some embodiments such that the groove bottom of the mounting portion 1210 is annular. The shape and size of the perforations 1212 may be adapted to the shape and size of the atomizing face 313 of the atomizing assembly 30 so that the atomizing face 313 of the atomizing assembly 30 is fully exposed to the atomizing chamber 120. The second conductive end 1132 of the electrode 113 of the base 11 extends into the through hole 1212 to resiliently abut the atomizing assembly 30. The outer surfaces of the second side wall 123 and the fourth side wall 127 may be provided with a clamping platform 122 in some embodiments, so as to be buckled with the buckling member 40. The outer surface of the first sidewall 121 may be planar in some embodiments.

The plane of the groove bottom of the mounting portion 1210 may in some embodiments be parallel to the longitudinal axis X of the atomizer 1, so that the atomizing assembly 30 is mounted in the mounting portion 1210 with its atomizing face 313 also parallel to the longitudinal axis X of the atomizer 1. It will be appreciated that the plane in which the groove bottom of the mounting portion 1210 is located is not limited to being parallel to the longitudinal axis X of the atomizer 1, but may be slightly inclined to the longitudinal axis X, and the inclined angle is preferably an inclined angle of less than 30 degrees.

As further shown in fig. 8, the connection cavity 13 may include a first sidewall 131, a second sidewall 133, a third sidewall 135, and a fourth sidewall 137 connected in sequence in a circumferential direction in some embodiments. The first, second, third and fourth sidewalls 131, 133, 135 and 137 together define a cylindrical cavity 130 in which the first seal 50 is embedded. The connecting chamber 13 may be integrally formed with the top of the atomizing chamber 12 in the longitudinal direction in some embodiments, and the third side wall 135 thereof is in a vertical plane with the third side wall 125 of the atomizing chamber 12. The distance connecting the first side wall 131 to the third side wall 135 of the chamber 13 is greater than the distance connecting the first side wall 121 to the third side wall 125 of the nebulizing chamber 12.

Referring to fig. 3, the outer wall surfaces of the first side wall 131 and the third side wall 135 are respectively abutted against the inner surfaces of the first side wall 211 and the third side wall 215 of the housing 21, so as to separate the liquid storage space 70 into a collecting portion 71 below the connecting cavity 13 and a liquid storage bin 72 above the connecting cavity 13. The pooling portion 71 is formed by gaps between the atomizing chamber 12 and the first, second, and fourth side walls 211, 213, 217 of the housing 21, and surrounds the atomizing chamber 12 in a C-shape.

Referring to fig. 4 together, the second side wall 133 and the fourth side wall 137 of the connecting chamber 13 are opposite to the second side wall 213 and the fourth side wall 217 of the housing 21, respectively, and form two gaps that communicate the pooling part 71 and the liquid storage part 72, respectively, to form the first liquid drain port 73 and the second liquid drain port 74 through which the liquid enters the pooling part 71 from the liquid storage part 72.

In some embodiments, the lower corners of the connection between the first side wall 131 and the second side wall 133 and the connection between the first side wall 131 and the fourth side wall 137 of the connecting cavity 13 are all rounded, so that the liquid can more smoothly enter the collecting portion 71 from the liquid storage bin 72, and the adhesion and residence of the air bubbles in the collecting portion 71 during the liquid discharging process are reduced, so as to prevent or reduce the dry burning problem caused by the adhesion of the air bubbles on the heating element 31.

The junction of the connecting chamber 13 with the atomizing chamber 12 may in some embodiments be provided with a step 132, the top surface of which is formed with a first air guide slot 1320 with capillary force that communicates with the atomizing chamber 120 and extends horizontally. The third sidewall 135 of the connection chamber 13 may include a longitudinally extending second air guide groove 1351 having a capillary force formed at an inner surface, in some embodiments, a lower end of the second air guide groove 1351 being in communication with the first air guide groove 1320. The third sidewall 135 can in some embodiments further include a longitudinally extending third air guide channel 1353 formed in the outer surface and having a capillary force and an air guide hole 1352 extending through the third sidewall 135 to communicate the third air guide channel 1353 with the second air guide channel 1351. The upper end of the third air guide groove 1353 is communicated with the liquid storage bin 72 of the liquid storage space 70. The first air guide groove 1320, the second air guide groove 1351, the air guide holes 1352 and the third air guide groove 1353 together form an air exchanging channel of the atomizer 1 so as to realize air-liquid balance in the liquid storage space 70.

In some embodiments, the atomization seat body of the atomization seat 10, which is composed of the base body 111, the atomization cavity 12, and the connection cavity 13, may be integrally injection molded. In this way, the formation of the atomization cavity 120 and the separation of the liquid storage part of the liquid storage space 70 can be mainly realized by a single part (atomization seat main body), so that the number of parts of the atomization main body 100 is greatly reduced, the assembly efficiency of the atomization main body 100 is improved, and the manufacturing cost of the whole atomization main body 100 is reduced. After the atomization seat main body is integrally formed, the joint gap between parts is reduced, and the leakage risk is also reduced.

As further shown in fig. 9, the first seal 50 may be made of a soft material such as silicone in some embodiments, and may include a cylindrical body 51 and a flange 53 formed at an upper side edge of the cylindrical body 51. The outer diameter of the cylindrical body 51 is adapted to the inner diameter of the receiving chamber 130 of the connecting chamber 13 so that the cylindrical body 51 can be tightly plugged into the receiving chamber 130 in the axial direction. The lower end surface of the cylindrical body 51 abuts against the top surface of the step 132. The cylindrical body 51 includes a central through hole 510 therethrough for communicating with the atomizing chamber 120 after the air conduit 22 of the housing 20 is inserted. The first seal 60 is also made of a soft material such as silicone in some embodiments and is in the form of a block.

As shown in fig. 12, the atomizing assembly 30 may in some embodiments include a sheet heating element 31 and a box-type soft seal 32 bonded to the periphery of the sheet heating element 31. The sheet heating element 31 may be in a square sheet shape in some embodiments, and may include a sheet-like substrate 311 and a heating layer 312 formed on an atomizing face 313 of the substrate 311.
