Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomization devices, in particular to an atomizer and an electronic atomization device. Background Art

[0002] The paste-type atomizer is a type of electronic atomization device. Traditional paste-type atomizers usually consist of three separate parts: a paste box, a paste spoon, and an atomizer. The paste box contains thick paste. The user scoops a little paste with the paste spoon and puts it into the heating chamber of the atomizer. Then, the atomizer is turned on to preheat and heat the paste. The user then inhales the generated aerosol.

[0003] In order to filter and dilute the generated aerosol, some e-cigarette paste atomizers are usually integrated with a filter container to form a filterable electronic atomizer device. The filter container is usually filled with pure water for filtering and diluting the smoke. The smoke generated by the atomizer is guided into the water for filtration and dilution. The aerosol overflowing from the water is then passed through a suction device and inhaled by the user. However, when the existing electronic atomizer device is shaken or turned over (such as in a bag, in a car, or in the hand, etc.), it is easy for water to enter the atomizer, thereby damaging the device.

[0053] The circuit board 141 can control the working state of the atomizer core 30 and the heating element 41 according to the switch state of the switch mechanism. For example, when it is detected that the upper body 10 rotates to the conduction position relative to the lower body 20, the atomizer automatically starts the preheating mode, and the circuit board 141 controls the battery 142 to supply power to the heating element 41, thereby heating and melting the paste in the oil cup 40 to flow into the atomizer core 30; when the user inhales, the switch of the microphone 143 is triggered, and the atomizer core 30 starts to work, thereby heating the atomized e-liquid to generate smoke for inhalation. When the atomizer is not in use, the upper body 10 and the lower body 20 are rotated in the opposite direction. When it is detected that the upper body 10 rotates to the closed position relative to the lower body 20, the circuit of the entire atomizer is disconnected, the conduction between the first air inlet 103a and the second air inlet 103b is closed, and the conduction between the first air inlet 106a and the second air inlet 106b is closed, and the atomizer cannot be started at this time.

The first bracket 171 is provided with a mounting hole 171a for mounting the oil cup 40, the heating element 41, the heat insulation cotton 42 and the atomizer core 30, wherein the oil cup 40, the heating element 41 and the heat insulation cotton 42 are arranged in the middle and upper part of the mounting hole 171a, and the atomizer core 30 is arranged in the lower part of the mounting hole 171a. Among them, the first bracket 171 and the second bracket 172 are both made of silicone material.

[0056] Furthermore, the lower shell 16 is provided with a mounting surface 164, and the circuit board 141 is mounted on the mounting surface 164. The circuit board 141 is installed in the second mounting groove 151 of the upper shell 15 together with the lower shell 16, so that the structure of the atomizer is more compact, thereby reducing the volume of the atomizer and facilitating carrying.

[0057] like Figure 1 As shown, the present application also provides an electronic atomization device, including the atomizer as described above and an external container 200, and the external container 200 is detachably connected to the fixed portion 21 of the atomizer body 100.

[0058] In summary, the working principle of the entire electronic atomization device is as follows:

[0059] 1. The oil cup 40 of the atomizer is pre-stored with a paste medium (smoke paste);

[0060] 2. Fix the atomizer in an external container 200 filled with liquid (such as water), and extend one end of the air guide tube 300 below the liquid surface;

[0061] 3. Rotate the upper body 10 and the lower body 20. When it is detected that the upper body 10 rotates to the conducting position relative to the lower body 20, the circuit switch and the airway (the air inlet 103 and the air intake 106) of the entire electronic atomization device are turned on, and the circuit board 141 controls the battery 142 to supply power to the heating element 41 outside the oil cup 40, thereby heating and melting the solid paste medium inside the oil cup 40;

[0062] 4. After preheating is completed, the user can open the nozzle cover 122 and inhale from the nozzle 11. The microphone 143 detects the negative pressure of suction, and the circuit board 141 controls the atomizer core 30 to start working, so as to heat the liquid medium flowing from the oil cup 40 into the inside of the atomizer core 30, and mix it with the air flowing from the air inlet 101 in the atomizer cavity 102 to form a suckable gas (smoke);

[0063] 5. The extractable gas is sequentially transmitted to the air guide tube 300 at the bottom through the first air inlet 103a, the first interface 103c, the third interface 103d, the second air inlet 103b and the air outlet 104, and is transmitted from the opening at the bottom of the air guide tube 300 to below the liquid surface;

[0064] 6. The gas coming out of the liquid is sucked by the user from the suction nozzle 11 through the return air port 105, the second air inlet 106b, the fourth interface 106d, the second interface 106c, the first air inlet 106a and the air inlet 107 in sequence;

[0065] 7. After the suction is completed, the upper body 10 and the lower body 20 are rotated in the opposite direction. When it is detected that the upper body 10 is rotated to the closed position relative to the lower body 20, the circuit of the entire atomizer is disconnected, the first air inlet 103a and the second air inlet 103b are closed, and the first air inlet 106a and the second air inlet 106b are closed. At this time, the atomizer cannot be started. Since the first air inlet 103a and the second air inlet 103b, and the first air inlet 106a and the second air inlet 106b are completely staggered, even if the entire electronic atomization device is turned upside down, the liquid in the external container 200 will not enter the interior of the atomizer through the airway (air inlet 103, air inlet 106), which can prevent the electronic atomization device from being flooded when it is flipped or shaken, thereby damaging the device.
