The electronic atomization device can be generally flat, and may include a flat housing 2 and an atomization assembly 1 disposed in the housing 2. A liquid storage cavity 20 for storing the liquid matrix and an air outlet channel 210 for guiding the smoke atomized by the atomization assembly 2 are formed in the housing 2. It can be understood that the electronic atomization device is not limited to being flat, and it can also be in other shapes such as cylindrical, elliptical cylindrical, cuboid-shaped, etc.

[0038] A ventilation pipe 21 can be longitudinally arranged in the housing 2. An annular liquid storage cavity 20 is defined between the outer wall surface of the ventilation pipe 21 and the inner wall surface of the housing 2, and an air outlet channel 210 is defined by the inner wall surface of the ventilation pipe 21. The ventilation pipe 21 can be integrally extended downward longitudinally from the top wall of the housing 2 and can be coaxially arranged with the housing 2. In other embodiments, the ventilation pipe 21 and the housing 2 can also be separately manufactured and then assembled together.

[0039] As Figure 1-4 shown, the atomization assembly 1 can include a base 11, a bracket assembly 15 disposed on the base 11, a heating track 14 wound outside the bracket assembly 15 for heating and atomizing the liquid matrix, a liquid absorbing member 13 sleeved outside the heating track 14 for adsorbing the liquid matrix, and a fixing member 12 sleeved outside the liquid absorbing member 13.

[0040] The base 11 is used to fix the bracket assembly 15 and the fixing member 12 to form a supporting force, and it can be made of insulating materials such as plastic and silica gel. Preferably, the base 11 is made of plastic. Generally, the base 11 will not deform when its working temperature is greater than or equal to 600 degrees. In some embodiments, the base 11 can include a lower seat body 111 at the lower part, an upper seat body 113 at the upper part, and a support arm 112 connecting the lower seat body 111 and the upper seat body 113. The lower seat body 111 can be tightly embedded in the lower end opening of the housing 2. The outer wall surface of the lower seat body 111 is sealingly fitted with the inner wall surface of the housing 2 to avoid liquid leakage. The outer shape of the lower seat body 111 is adapted to the shape of the lower end opening of the housing 2. In this embodiment, the lower seat body 111 is generally elliptical cylindrical. A flange 114 can also be horizontally extended outward from the outer circle of the bottom of the lower seat body 111, and the flange 114 can abut against the lower end surface of the housing 2. An air inlet hole 110 communicating with the outside can be longitudinally opened at the bottom of the lower seat body 111, and the cross-section of the air inlet hole 110 can be a narrow and long rectangle. It can be understood that in other embodiments, the cross-section of the air inlet hole 110 can also be in other regular or irregular shapes such as square, circular, elliptical, etc. In some other embodiments, the air inlet hole 110 can also be opened on the housing 2.

[0041] The support arm 112 can be generally plate-shaped and can extend upward from the top wall of the lower seat body 111. The upper seat body 113 is supported above the support arm 112, and there is a certain interval between the upper seat body 113 and the lower seat body 111. The upper seat body 113, the support arm 112, and the lower seat body 111 jointly define a receiving space for receiving the bracket assembly 15, the heating track 14, and the liquid absorbing member 13. The cross-sectional shape of the upper seat body 113 can be a regular or irregular shape such as a polygon, a trapezoid, a square, an equilateral triangle, a circle, an ellipse, etc. The upper seat body 113 can also be provided with a ventilation hole 1130 that communicates the air inlet hole 110 and the air outlet channel 210.

[0042] On the top wall of the lower seat body 111 corresponding to the air inlet hole 110, a protruding portion 115 can also protrude. The protruding portion 115 can include a lower protruding portion 1151 located at the lower part, an upper protruding portion 1153 located at the upper part, and a connecting portion 1152 connecting the lower protruding portion 1151 and the upper protruding portion 1153. The lower protruding portion 1151 is annular and is arranged around the air inlet hole 110. It can extend upward from the top wall of the lower seat body 111 to prevent the liquid leakage received on the lower seat body 111 from leaking out through the air inlet hole 110. The upper protruding portion 1153 is plate-shaped and is correspondingly arranged above the lower protruding portion 1151 to prevent the liquid matrix located above from falling into the air inlet hole 110 and causing liquid leakage. The connecting portion 1152 can extend upward from the top wall of the lower protruding portion 1151, and a ventilation groove 1150 communicating the air inlet hole 110 and the ventilation hole 1130 can be formed thereon.

[0043] The bracket assembly 15 is clamped and fixed between the upper seat body 113 and the lower seat body 111. The outer shape of the bracket assembly 15 can be adapted to the outer shape of the upper seat body 113, and a atomization cavity 10 communicating with the ventilation groove 1150 and the ventilation hole 1130 respectively is formed therein. The upper and lower ends of the bracket assembly 15 can be connected to the upper seat body 113 and the lower seat body 111 respectively by means of riveting, plugging, or hot pressing, etc., to enhance the supporting force and strength of the bracket assembly 15. Spiral limiting rail grooves 150 arranged at equal or unequal intervals can be formed on the outer side of the bracket assembly 15, and the heating track 14 is spirally wound in the limiting rail grooves 150. By using the limiting rail grooves 150 to fully and evenly layout the heating track 14 on the bracket assembly 15, the limiting and fixing of the heating track 14 can be enhanced, so that the heating track 14 will not be deformed and will not be in poor contact with the liquid matrix adsorbed on the liquid absorbing member 13 due to warping caused by high temperature or other reasons. The heating track has good consistency and good atomization effect. In addition, the spiral pitch of the heating track 14 can be adjusted by adjusting the spiral pitch of the limiting rail grooves 150. In some embodiments, the spiral pitch between the heating tracks 14 can be 0.1 - 3 mm.

[0044] The bracket assembly 15 can generally withstand temperatures of 200 to 800 degrees, and its material can be a metal conductive material or an insulating material. When the bracket assembly 15 is a metal conductive material, it can also be electrically connected to the heating track 14. The heating track 14 is wound around the bracket assembly 15 and can atomize the liquid matrix adsorbed on the atomizing liquid member 13 after being energized and heated through the bracket assembly 15. The heating track 14 generally can use a conductive material with a relatively large resistivity and more heat generation, such as metal materials with conductive properties and more heat generation after being energized, such as iron-chromium-aluminum, nickel-chromium, stainless steel, pure nickel, pure titanium, nickel-iron, etc. The heating track 14 can be in the form of a filament or a strip, and its cross-sectional shape can be a regular or irregular shape such as a circle, an ellipse, a square, a trapezoid, a triangle, a polygon, etc.

[0045] In some embodiments, the bracket assembly 15 may include a plurality of limiting posts 151 and a plurality of support posts 152. The plurality of limiting posts 151 are used to form a limiting rail groove 150 for the heating track 14 to be spirally wound. Specifically, a plurality of limiting grooves 1510 distributed at equal or unequal intervals can be formed longitudinally on the limiting posts 151. The limiting rail groove 150 may include a plurality of continuous limiting grooves 1510 on the limiting posts 151 and / or a plurality of limiting grooves 1510 spaced apart by several limiting grooves 1510. The plurality of limiting posts 151 and the plurality of support posts 152 can be arranged at a certain interval into different shapes, so as to form a heating track 14 with different shapes. In addition, the limiting posts 151 and / or the support posts 152 can also be used as the positive and negative electrode posts of the heating track 14 to connect to the power supply.

[0046] In this embodiment, the bracket assembly 15 includes four sheet-like limiting posts 151 and two cylindrical support posts 152. The outer side surface of the limiting post 151 is in the shape of triangular serrations distributed at equal intervals, and a triangular limiting groove 1510 is formed between every two adjacent serrations. Two of the limiting posts 151 can be respectively attached and installed on two opposite sides of the support arm 112 in the width direction and can be respectively used as the positive and negative electrode posts of the heating track 14 to connect to the power supply. The heating track 14 can be formed by winding a heating track wire or a flat belt around the support arm 112 and the outer sides of the four limiting posts 151 and the two support posts 152 according to set parameters. After winding is completed, it can be along Figure 5The cutting line A shown cuts the heating trace wire or flat belt to form the heating trace 14. The cutting line A can be located between two positive and negative electrode posts and can be parallel to the axial direction of the heating trace 14. In this embodiment, the heating trace 14 is wound around the limiting post 151 at equal intervals and continuously. In other embodiments, the heating trace 14 can also be wound around the limiting post 151 at equal intervals with several limiting grooves 1510 spaced therebetween, or wound around the limiting post 151 at unequal intervals with several limiting grooves 1510 spaced therebetween. In still other embodiments, the bracket assembly 15 can also be composed only of the limiting post 151; the limiting post 151 can also be in other shapes such as cylindrical, elliptical cylindrical, trapezoidal columnar, annular with an opening or closed annular, and the support post 152 can also be in other shapes such as sheet-shaped, elliptical cylindrical, trapezoidal columnar, annular with an opening or closed annular.

[0047] The liquid absorption member 13 is coated on the outer side of the heating trace 14 and is in liquid guiding communication with the liquid storage cavity 20. It can usually be absorbent cotton. The cross-section of the liquid absorption member 13 can be in the shape of an annular with an opening, which is convenient for being clamped to the outer side of the heating trace 14. The opening direction of the liquid absorption member 13 can face the support arm 112. In other embodiments, the liquid absorption member 13 can also be in the shape of a closed ring.

[0048] The fixing member 12 is sleeved outside the liquid absorption member 13 and is used for fixing and locking the liquid absorption member 13 and controlling the magnitude of the liquid flow rate to prevent dry burning or liquid explosion caused by excessive liquid. At least one (three in this embodiment) liquid inlet 120 for guiding liquid communication between the liquid storage cavity 20 and the liquid absorption member 13 is formed on the fixing member 12. The liquid matrix stored in the liquid storage cavity 20 can flow into the liquid absorption member 13 through the at least one liquid inlet 120 and be adsorbed by the liquid absorption member 13. The shape of the fixing member 12 corresponds to that of the liquid absorption member 13, and its cross-section is also in the shape of an annular with an opening, which is convenient for being clamped to the outer side of the liquid absorption member 13.

[0049] The fixing member 12 can also be fixed to the base 11 by mutual buckling. In this embodiment, a clamping groove 121 can be respectively formed by concave inward on the two side top walls of the fixing member 12, and a clamping hook 1131 can be respectively formed by extending downward on the two sides of the upper seat body 113. The clamping groove 121 and the clamping hook 1131 are mutually buckled to buckle and fix the fixing member 12 on the base 11. A chamfer or arc surface beneficial for guiding can also be provided on the clamping hook 1131 to facilitate assembly.

[0050] In some embodiments, the atomization component 1 may further include a pressing member 16 for pressing and fixing the heating track 14 onto the support arm 112 and riveting the heating track 14, so that the heating track 14 is in good contact with the support arm 112. The pressing member 16 may be generally sheet-shaped, and may be pressed onto the support arm 112 by means of riveting, hot pressing, stamping, etc., or may also be welded to the support arm 112 by means of ultrasonic welding, etc. At least one pressing post 161 extending longitudinally may protrude from the side of the pressing member 16 facing the support arm 112, and at least one pressing groove 1121 may be recessed on the side of the support arm 112 facing the pressing member 16 corresponding to the at least one pressing post 161. The heating track 14 is pressed onto the support arm 112 by the combination of the at least one pressing post 161 and the at least one pressing groove 1121, and the heating track 14 is tightened, so that the heating track 14 is in close contact with the liquid absorbing member 13 without generating gaps, avoiding dry burning. Moreover, the heating track 14 can be in good contact with the limiting post 151, so that the contact resistance generated is the lowest. In this embodiment, there are two pressing posts 161 and two pressing grooves 1121 respectively, and the cross-sections of the pressing posts 161 and the pressing grooves 1121 are both semi-circular arcs. In other embodiments, the number of the pressing posts 161 and the pressing grooves 1121 may also be one or more than two, and the cross-sections of the pressing posts 161 and the pressing grooves 1121 may also be other shapes such as triangles, squares, trapezoids, etc. A limiting hook 1122 may also protrude from the top of the side of the support arm 112 facing the pressing member 16 to clamp and limit the top of the pressing member 16 within the limiting hook 1122. The limiting hook 1122 may also be provided with an inclined surface or an arc surface conducive to guiding for easy assembly.

[0051] In some embodiments, the electronic atomization device may further include a sealing sleeve 3 sleeved outside the upper seat body 113. A through hole 30 is formed longitudinally on the sealing sleeve 3, and the lower end of the air vent pipe 21 may be closely embedded in the through hole 30 and may communicate with the air vent hole 1130 via the through hole 30. The sealing sleeve 3 may be made of an elastic material such as silica gel, and may include a lower sleeved portion 31 located at the lower part and sleeved outside the upper seat body 113 and an upper sleeved portion 32 located at the upper part and sleeved outside the air vent pipe 21.

[0052] Herein, the air intake hole 110, the air vent groove 1150, the atomization chamber 10, the air vent hole 1130, the through hole 30, and the air outlet channel 210 are sequentially connected to form a complete mist delivery channel. When the electronic atomization device is working, the liquid matrix stored in the liquid storage chamber 20 enters through at least one liquid inlet 120 and is adsorbed by the liquid absorbing member 13. When the heating track 14 is powered on and heated, the liquid matrix on the liquid absorbing member 13 in contact with the heating track 14 is atomized and evaporated into atomized steam. At the same time, external air enters the atomization chamber 10 through the air intake hole 110 of the mist delivery channel to be mixed with the atomized steam, and the smoke after the mixture of the atomized steam and the air flows out through the air outlet channel 210 of the mist delivery channel for inhalation.

[0056] S3: After the heating trace wire or flat belt is arranged according to the set parameters, then use an automatic cutting machine to cut off the heating trace wire or flat belt between the two electrode posts used as positive and negative electrode posts to form the heating trace 14. For example, it can be cut according to the cutting line A shown; Figure 5 shown in the cutting line A;

[0057] S4: After cutting, use a riveting press to press and fit the place where the pressing part 16 is combined with the support arm 112 of the base 11, so that the pressing part 16 is fully in contact with the electrode post and tightens the heating trace 14;

[0058] S5: Horizontally clamp the liquid absorption part 13 outside the heating trace 14 according to the parameter shape, so that the liquid absorption part 13 is fully in contact with the heating trace 14;

[0059] S6: Horizontally clamp the fixing part 12 outside the liquid absorption part 13 and fasten it with the base 11, further making the liquid absorption part 13 fully in contact with the heating trace 14, so as to prevent dry burning and inconsistent taste.
