The battery holder 11 is provided with a first connecting member 111 on the side surface outer wall of one end of the power supply shell opening 100 and a plunger 112 on the end face thereof.

[0048] The battery holder 11 is also provided with a first positive electrode and a first negative electrode 113 on one end of the power supply shell opening 100.

In this way, when the fixing pin 102 is inserted into the fixing hole 110, the beveled structure at the front end of the flange 1022 can be guided forward and inward, so that the clamping leg 1021 continues to be inserted forward into the fixing hole 110, and after being inserted in place, the flange 1022 can be clamped to the inner edge of the fixing hole 110, so that the fixing pin 102 is fixed in the fixing hole 110 and cannot be pulled out, and at the same time, the tail end of the fixing pin 102 is clamped in the pin hole 101. Therefore, the fixing pin 102 can firmly connect and fix the battery support 11 and the power supply shell 10. In the embodiment of the application, the fixing pin 102 is composed of a light-transmitting material, and the battery support 11 is provided with an LED indicator lamp at the fixing hole 110.

[0050] As shown in Figure 2 , Figure 7 , Figures 11-15 As shown, the atomization assembly 2 is composed of an atomization shell 20 and a suction nozzle shell 29, and the atomization shell 20 is provided with a liquid storage cavity 21, an atomization channel 22 and an atomization seat 23. The upper end of the atomization shell 20 is provided with an atomization shell opening 200, the inner wall of the atomization shell opening 200 is provided with a second connecting member 201, the atomization seat 23 is sealed to the inner wall of the atomization shell 20 below the second connecting member 201 in the atomization shell opening 200, the atomization seat 23 is provided with an air inlet hole 2310 which is in communication with the atomization channel 22, and the atomization seat 23 is further provided with a liquid injection hole 2320 which is in communication with the liquid storage cavity 21. The end surface of the atomization seat 23 is provided with a second positive electrode 241 and a second negative electrode 241.

[0051] The bottom of the atomization shell 20 is provided with an air outlet hole 25, and the bottom of the atomization seat 23 is provided with an upwardly recessed atomization cavity 2311 which is in communication with an air inlet hole 2310. The atomization cavity 2311 is transversely provided with an atomization unit 24, and the atomization cavity 2311 and the air outlet hole 25 are connected by an atomization pipe 26. The atomization channel 22 is formed by the air inlet hole 2310, the atomization cavity 2311, the atomization pipe 26 and the air outlet hole 25. The atomization pipe 26 and the air outlet hole 25 are further provided with a second sealing member 28 for sealing.

[0052] The atomization unit 24 includes a liquid guide strip and a heating resistor (not shown in the figure) mounted on the liquid guide strip. The liquid guide strip can absorb the atomization liquid in the liquid storage cavity, and the heating resistor can heat and evaporate the atomization liquid into steam, vapor mist or aerosol.

[0053] As shown in Figure 14 , Figure 15 , the atomization seat 23 includes a first atomization seat 231 and a second atomization seat 232 which are formed integrally by different materials. The first atomization seat 231 is made of a hard material resistant to corrosion and high temperature, such as PPS, PPS+glass fiber, glass fiber, nylon, nylon+glass fiber, etc., considering that the first atomization seat 231 is in contact with the atomization liquid for a long time. Such a hard material resistant to corrosion and high temperature makes the first atomization seat 231 suitable for long-term immersion in the atomization liquid without being damaged, and also avoids decomposition or degradation of the material to dissolve harmful components into the solution to be atomized in the liquid storage cavity. The second atomization seat 232 is made of a soft sealing material, such as silica gel or rubber, considering that the second atomization seat 232 is mainly used for sealing. The atomization unit 24, the atomization cavity 2311, the liquid guide groove 2312 and the air inlet hole 2310 are provided on the first atomization seat 231, and the liquid injection hole 2320 is provided on the second atomization seat 232.

[0054] As shown in Figure 1 , Figures 7-9 , the outer wall of the atomization shell 20 is provided with an observation window 202 made of a see-through material for observing the atomization liquid in the liquid storage cavity 21.

[0055] As shown in Figure 1 , Figure 16 , Figure 17 , the upper end of the suction shell 29 is provided with a suction shell opening 30, and the lower end of the suction shell 29 is provided with a suction port 31 for sucking the aerosol. The suction shell 29 is upwardly sleeved on the lower outer wall of the atomization shell 20 from the opening 30 thereof, and the suction port 31 is in communication with the atomization channel 22.

[0056] As shown in Figures 11-17As shown, the suction port 31 of the suction shell extends upward and is connected with a suction tube 311, the suction tube 311 is connected with the air outlet hole 25 of the atomization shell, and a first sealing element 310 is further arranged between the suction tube 311 and the air outlet hole 25. The suction port 31 of the suction shell further extends upward and is connected with a trumpet-shaped blocking ring 312, the blocking ring 312 is arranged in the suction tube 311, and the blocking ring 312 and the suction tube 311 together form a liquid blocking groove 313. The blocking ring 312 can block the condensed liquid or small droplets in the atomized mist and collect them in the liquid blocking groove 313, so as to avoid the condensed liquid or small droplets from being sucked into the user's mouth and causing the user to have a bad user experience. The lower two side outer walls of the atomization shell 20 are provided with second buckles 27, and the upper two side inner walls of the suction shell 29 are provided with second clamping grooves 314 which are connected with the second buckles 27. In other embodiments, the second buckles 27 can also be designed as clamping grooves, and the second clamping grooves 314 can also be designed as buckles.

[0057] As shown in Figures 1-3 , Figures 6-9 The first connecting member 111 is specifically designed as a first buckle 111, and the second connecting member 201 is specifically designed as a first clamping groove 201, and the first buckle 111 is connected with the first clamping groove 201. When the first buckle 111 approaches the first clamping groove 201, the first buckle 111 has an inclined surface structure in the approaching direction, so that the first buckle 111 can enter the first clamping groove 201, but in the opposite direction, the first buckle 111 is a right angle structure, which is clamped in the first clamping groove 201 and cannot be taken out, so that the atomization assembly 2 and the power supply assembly 1 cannot be disassembled. In the present application, the connection and fixation of the atomization assembly 2 and the power supply assembly 1 is achieved by the mutual clamping connection of the first clamping groove 201 arranged on the atomization shell 20 and the first buckle 111 arranged on the battery support 11, which is more firm than the clamping connection between the atomization shell 20 and the power supply shell 10. When the clamping connection is arranged between the atomization shell 20 and the power supply shell 10, the clamping is relatively shallow due to the thinness of the power supply shell 10, and the power supply shell 10 is easy to deform and cause the clamping to slip off.

[0058] As shown in Figure 18As shown, the electronic atomization device of the present application (here the mouthpiece of the electronic atomization device is placed vertically with the mouthpiece upward), the working principle is as follows: when the user inhales, negative pressure is generated at the mouthpiece 31, ambient gas is sucked into the lower part of the atomization seat 23 from the gap between the atomization assembly 2 and the power assembly 1, and then flows upward through the air inlet hole 2310 of the atomization seat, and then in the atomization cavity 2311, the atomization unit 24 heats and atomizes the atomization liquid from the liquid storage cavity into vapor mist or aerosol, which continues to flow upward through the mist outlet channel 22 to the mouthpiece 31, and the direction of gas flow is shown by the continuous arrow a in the figure. When the user inhales, negative pressure is generated in the lower part of the atomization seat 23, the airflow sensing channel (not shown in the figure) of the power assembly 1 has upward flowing gas, and because the airflow sensing channel is connected to the start switch 115, the start switch 115 is triggered by sensing the airflow at this time, and the heating resistor of the atomization unit 24 is started to work, and the atomization liquid is heated and atomized into vapor mist or aerosol.

[0059] As shown in the figure, Figures 1-17 The electronic atomization device of the present application is produced by assembling the power assembly 1 and the atomization assembly 2 respectively, then injecting liquid into the atomization assembly 2, and finally installing the power assembly 1 on the atomization assembly 2. In order to avoid leakage of the atomization liquid during long-distance transportation, the electronic atomization device of the present application is not injected with liquid at the production site, but the power assembly 1, the atomization assembly 2 and the atomization liquid are packaged and transported separately, and the last step of assembly is performed after the liquid is injected at the sales destination.

[0060] As shown in the figure, Figure 1 , Figure 12 After arriving at the sales destination, the atomization assembly 2 is inverted, that is, it is placed vertically with the mouthpiece 31 downward and the liquid injection hole 2320 upward, and after injecting the atomization liquid into the liquid storage cavity 21 through the liquid injection hole 2320, the power assembly 1 is downwardly sleeved on the upper outer wall of the atomization shell 20 from the opening 100 of the power shell, when the sleeve is in place, the end outer wall of the battery support 11 is inserted into the inner wall at the opening 200 of the atomization shell, the first protruding buckle 111 is non-detachably connected with the first clamping groove 201, so that the power assembly 1 is connected and fixed with the atomization assembly 2, and at the same time the plunger 112 is blocked in the liquid injection hole 2320, the liquid storage cavity 21 is conveniently completed with liquid injection and blocked by the plunger to avoid liquid leakage, and the first positive electrode and the first negative electrode 113 are respectively in contact with the second positive electrode and the second negative electrode 241 to ensure that the atomization unit 24 can be powered to heat and atomize.

[0061] The above description is only the preferred embodiment of the present application, and the above specific embodiment is not a limitation of the present application. Various modifications and changes can occur within the scope of the technical idea of the present application, and any modification, change or equivalent replacement made by those skilled in the art based on the above description shall fall within the scope of the present application.
