[0039] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0040] Figure 1-6The atomizer in the first embodiment of the present invention is shown. The atomizer can form a roughly flat electronic atomization device together with a power supply device (not shown), which is used for heating and atomizing liquid substrates such as cigarette liquid and liquid medicine. The atomizer is used to accommodate the liquid substrate, heat and atomize the liquid substrate, and transport the mist. The power supply device is used to power the atomizer and control the opening or closing of the entire electronic atomization device. It can be understood that the electronic atomization device is not limited to being flat, and it can also be cylindrical, elliptical, rectangular, and other shapes.

[0041] like Figure 2-6 As shown, the atomizer may include a shell 1 having a liquid storage chamber 10 for storing a liquid matrix and an air outlet channel 110 for conducting mist, an atomization assembly 2 arranged in the shell 1, and a fixing member 3 sleeved on the bottom of the shell 1.

[0042] The housing 1 may be generally flat, and a vent pipe 11 may be longitudinally arranged inside the housing 1, the outer wall surface of the vent pipe 11 and the inner wall surface of the housing 1 define a liquid storage chamber 10, and the inner wall surface of the vent pipe 11 defines an air outlet channel 110. The vent pipe 11 may be formed by the top wall of the housing 1 extending downward in the longitudinal direction, and may be coaxially arranged with the housing 1. In other embodiments, the vent pipe 11 and the housing 1 may also be manufactured separately and then assembled together.

[0043] The atomizing assembly 2 may include a base 24 embedded in the bottom of the housing 1, two electrode columns 25 disposed on the base 24, a liquid-conducting body 22 disposed on the base 24, a heating body 23 disposed on the liquid-conducting body 22 and electrically connected to the two electrode columns 25, and a sealing member 21 sleeved on the liquid-conducting body 22 and the base 24. The liquid-conducting body 22 has a liquid-absorbing surface 221 in liquid-conducting communication with the liquid storage chamber 10 and an atomizing surface 222 for mounting the heating body 23. The direction of the airflow flowing through the atomizing surface 222 is parallel to the atomizing surface 222, and the atomizing effect is more sufficient.

[0044] In some embodiments, the liquid-conducting body 22 may be a porous ceramic liquid-conducting body, which may include a horizontally arranged liquid-absorbing portion 225 in the shape of a rectangular plate, a rectangular plate-shaped body portion 223 extending downward from one side of the long side of the liquid-absorbing portion 225, and an extension portion 224 extending downward from the middle of the bottom surface of the body portion 223. The liquid-absorbing surface 221 is located on the top surface of the liquid-absorbing portion 225, the atomizing surface 222 is located on one side of the body portion 223 along the thickness direction, and the liquid-absorbing surface 221 is perpendicular to the atomizing surface 222. The liquid-absorbing portion 225 may also be provided with an air outlet hole 2250 connected to the air outlet channel 110 in the longitudinal direction. Two electrode pins 231 respectively connected to the two ends of the heating element 23 are arranged on the bottom surface of the body portion 223 and are respectively located on both sides of the extension portion 224. The two electrode columns 25 are respectively in contact with the two electrode pins 231 for easy assembly.

[0045] In some embodiments, the seal 21 may be made of a flexible material such as silicone, and may include a main body 211 located at the bottom and a sleeve portion 212 located at the top. A liquid inlet hole 2110 for connecting the liquid-conducting liquid 22 with the liquid storage chamber 10 is longitudinally opened on both sides of the top surface of the main body 211 along the length direction. The liquid inlet hole 2110 may be a narrow and long rectangular hole. In other embodiments, it may also be in other shapes such as round, oval, square, etc. The main body 211 is sealed and embedded in the housing 1. The upper outer ring of the main body 211 may protrude to form at least one circle of annular protrusions 2111. The annular protrusions 2111 are interference fit with the inner wall surface of the housing 1, which is conducive to improving the effectiveness and reliability of the seal. The bottom of the main body 211 is connected to form a first cavity 2113 and a second cavity 2112 from bottom to top. The cross-sectional dimensions of the first cavity 2113 are larger than those of the second cavity 2112. The upper part of the base 24 can be tightly embedded in the first cavity 2113, and the liquid suction part 225 of the liquid guide 22 can be tightly embedded in the second cavity 2112. The sleeve part 212 is formed by extending upward from the top surface of the main body 211. A through hole 2120 is formed in the longitudinal direction of the sleeve part 212. The first cavity 2113, the second cavity 2112, and the through hole 2120 are connected in sequence from bottom to top. The lower end of the vent pipe 11 can be tightly embedded in the sleeve part 212 and connected to the through hole 2120. The inner circle of the sleeve part 212 can also extend inward to form a flange 2121, and the lower end face of the vent pipe 11 can abut against the flange 2121.

[0046] In some embodiments, the base 24 may be made of plastic material, and may include a lower base body 241 located at the bottom, which is approximately in the shape of an elliptical plate, a middle base body 242 located in the middle, which is approximately in the shape of an elliptical ring, and an upper base body 243 located at the top, which is approximately in the shape of an elliptical ring. The outer dimensions of the lower base body 241, the middle base body 242, and the upper base body 243 decrease in sequence. The outer dimensions of the lower base body 241 are larger than the inner dimensions of the shell 1, and the upper end surface of the lower base body 241 is tightly against the lower end surface of the shell 1. The middle base body 242 is tightly embedded in the shell 1, and the upper base body 243 is tightly embedded in the first cavity 2113 of the main body 211. An atomizing cavity 220 connected to the air outlet 2250 is formed between the atomizing surface 222 of the liquid-conducting liquid 22 and the inner wall surface of the upper base body 243.

[0047] The top of the lower seat body 241 extends upward to form two clamping arms 245 to tightly clamp the main body 223 of the liquid guide 22 between the two clamping arms 245. The lower seat body 241 may also be provided with an air inlet 240 in the longitudinal direction to allow external air to enter the atomization chamber 220. The top of the lower seat body 241 extends upward to form a boss 244, and the boss 244 is provided with at least one vent 2440 connected to the air inlet 240, which can prevent the condensate received on the lower seat body 241 from leaking through the air inlet 240. The top surface of the lower seat body 241 may also be concave to form a receiving groove 2411, and the extension 224 of the liquid guide 22 may extend into the receiving groove 2411. The receiving groove 2411 can be used to receive the condensate generated during the long-term atomization process, and the condensate received in the receiving groove 2411 can flow to the main body 223 through the extension 224 for secondary atomization. It can be understood that the shapes and numbers of the extension portions 224 and receiving grooves 2411 are not limited.

[0048] Thus, the air inlet 240, the air vent 2440, the atomizing chamber 220, the air outlet 2250, the through hole 2120, and the air outlet channel 110 are connected in sequence from bottom to top to form a complete mist delivery channel.

[0049] The fixing member 3 is sleeved outside the shell 1 and the lower seat 241. It can be formed by stamping and stretching of metal materials, which plays a fixing and decorative role, and can also reduce the influence of thermal expansion and contraction on the assembly structure. A mutually matching snap-in structure can also be provided between the fixing member 3 and the shell 1. In this embodiment, the outer wall surface of the shell 1 protrudes outward to form a card platform 12, and the fixing member 3 is formed with a card slot 31 corresponding to the card platform 12. The card platform 12 is buckled with the card slot 31, and the fixing member 3 and the shell 1 are buckled and fixed. It can be understood that in other embodiments, the fixing member 3 may not be provided, and the atomizer assembly 2 is directly fixed in the shell 1 by the base 24 and the shell 1 through a matching structure such as a tight fit or a snap fit.

[0050] Figure 7-11 The atomizer in the second embodiment of the present invention is shown. The atomizer can form a roughly flat electronic atomization device together with a power supply device (not shown), which is used for heating and atomizing liquid substrates such as cigarette liquid and liquid medicine. The atomizer is used to accommodate the liquid substrate, heat and atomize the liquid substrate, and transport the mist. The power supply device is used to power the atomizer and control the opening or closing of the entire electronic atomization device. It can be understood that the electronic atomization device is not limited to being flat, and it can also be cylindrical, elliptical, rectangular, and other shapes.

[0051] The atomizer may include a housing 1 having a liquid storage chamber 10 for storing a liquid matrix and an air outlet channel 110 for guiding out mist, an atomizing assembly 2 disposed in the housing 1 , and a fixing member 3 sleeved on the bottom of the housing 1 .

The vent pipe 11 may be formed by the top wall of the housing 1 extending downward in the longitudinal direction, and may be coaxially arranged with the housing 1. In other embodiments, the vent pipe 11 and the housing 1 may also be manufactured separately and then assembled together.

[0053] The atomizing assembly 2 may include a base 24 embedded in the bottom of the housing 1, two electrode columns 25 disposed on the base 24, a liquid-conducting body 22 disposed on the base 24, a heating body 23 disposed on the liquid-conducting body 22 and electrically connected to the two electrode columns 25, and a sealing member 21 sleeved on the liquid-conducting body 22 and the base 24. The liquid-conducting body 22 has a liquid-absorbing surface 221 in liquid-conducting communication with the liquid storage chamber 10 and an atomizing surface 222 for mounting the heating body 23. The direction of the airflow flowing through the atomizing surface 222 is parallel to the atomizing surface 222, and the atomizing effect is more sufficient.

[0054] In some embodiments, the liquid conductor 22 may be a porous ceramic liquid conductor in a roughly T-shaped sheet shape, which may include a square sheet-shaped main body portion 223 located at the upper portion and an extension portion 224 extending downward from the middle of the bottom surface of the main body portion 223. The liquid absorption surface 221 and the atomization surface 222 are respectively located at two opposite sides of the main body portion 223 along the thickness direction. Two electrode pins 231 respectively connected to the two ends of the heating element 23 are arranged on the bottom surface of the main body portion 223 and are respectively located on both sides of the extension portion 224. The two electrode columns 25 are respectively in contact with the two electrode pins 231 for easy assembly.

[0055] In some embodiments, the seal 21 may be made of a flexible material such as silicone, and may include a main body 211 located at the bottom and a sleeve portion 212 located at the top. A liquid inlet hole 2110 is formed on the main body 211 to connect the liquid-conducting liquid 22 with the liquid storage chamber 10, and the liquid inlet hole 2110 may extend inward from one side of the main body 211 along the width direction. The main body 211 is sealed and embedded in the housing 1, and the lower outer ring of the main body 211 may protrude to form at least one circle of annular protrusions 2111, and the annular protrusions 2111 are interference fit with the inner wall surface of the housing 1, which is conducive to improving the effectiveness and reliability of the seal. The top of the main body 211 extends downward to form two L-shaped clamping portions 213, and the main body 223 of the liquid-conducting liquid 22 is clamped between the two clamping portions 213. The sleeve portion 212 is formed by extending upward from the top surface of the main body 211. A through hole 2120 is formed in the longitudinal direction of the sleeve portion 212. The lower end of the vent pipe 11 can be tightly embedded in the sleeve portion 212 and communicate with the through hole 2120. The inner circle of the sleeve portion 212 can also extend inward to form a flange 2121, and the lower end surface of the vent pipe 11 can abut against the flange 2121.

The outer dimensions of the lower base body 241, the middle base body 242, and the upper base body 243 are reduced in sequence. The outer dimensions of the lower base body 241 are larger than the inner dimensions of the shell 1, and the upper end surface of the lower base body 241 is tightly against the lower end surface of the shell 1. The middle base body 242 is tightly embedded in the shell 1, and the upper base body 243 is tightly embedded in the main body 211. An atomizing chamber 220 connected to the through hole 2120 is formed between the atomizing surface 222 of the liquid-conducting body 22 and the inner wall surface of the upper base body 243.

[0057] The top of the lower seat body 241 extends upward to form two clamping arms 245 to tightly clamp the two clamping portions 213 of the seal 21 between the two clamping arms 245. The lower seat body 241 may also be provided with an air inlet 240 in the longitudinal direction to allow outside air to enter the atomization chamber 220. The top of the lower seat body 241 extends upward to form a boss 244, and the boss 244 is provided with at least one vent 2440 connected to the air inlet 240, which can prevent the condensate received on the lower seat body 241 from leaking through the air inlet 240. The top surface of the lower seat body 241 may also be concave to form a receiving groove 2411, and the extension portion 224 of the liquid guide 22 may extend into the receiving groove 2411. The receiving groove 2411 can be used to receive the condensate generated during the long-term atomization process, and the condensate received in the receiving groove 2411 can flow to the main body 223 through the extension portion 224 for secondary atomization. It can be understood that the shapes and numbers of the extension portions 224 and receiving grooves 2411 are not limited.

[0058] Thus, the air inlet 240, the air vent 2440, the atomizing chamber 220, the through hole 2120, and the air outlet channel 110 are sequentially connected from bottom to top to form a complete mist delivery channel.

[0059] The fixing member 3 is sleeved outside the shell 1 and the lower seat 241.

A mutually matching snap-in structure can also be provided between the fixing member 3 and the shell 1. In this embodiment, the outer wall surface of the shell 1 protrudes outward to form a card platform 12, and the fixing member 3 is formed with a card slot 31 corresponding to the card platform 12. The card platform 12 is buckled with the card slot 31, and the fixing member 3 and the shell 1 are buckled and fixed. It can be understood that in other embodiments, the fixing member 3 may not be provided, and the atomizer assembly 2 is directly fixed in the shell 1 by the base 24 and the shell 1 through a matching structure such as a tight fit or a snap fit.

In addition, a positioning platform 13 may be formed on the inner wall surface of the housing 1, and the top surface of the main body 211 may be against the positioning platform 13 to achieve positioning of the atomizer assembly 2 during installation.
