[0002] The electronic atomization device operates the battery through airflow sensing or button pressing, connects to the atomizer, generates heat, evaporates the smoke oil, produces an atomization effect, and achieves an effect similar to smoking. It uses smoke liquid containing nicotine (from high to low), and finally to smoke liquid with a nicotine concentration of 0, to replace ordinary cigarettes to relieve addiction. The electronic atomization device is mainly assembled with an atomization component and a power supply component. The power supply component is used to provide energy to the atomization component. The atomization component heats the liquid matrix and atomizes it to form an aerosol that can be inhaled by the user. It is mainly used for quitting smoking. Since the electronic atomization device does not contain tar, suspended particulate matter and other harmful ingredients in traditional cigarettes, it has gradually become popular in the market. With the improvement of living standards, users have higher and higher requirements for electronic atomization devices and are no longer satisfied with a single flavor. Flavor cartridges came into being, which further promoted the technical development of electronic atomization devices and a structure combining flavor cartridges and atomizers appeared.

Therefore, a detachable electronic atomizing device is needed to solve the above problems. Summary of the invention

[0034] The working principle of the present invention is:

[0035] When it is necessary to separate the atomizer assembly 7, the clamping plates 20 on the left and right sides of the connecting sleeve 3 can be squeezed. The two clamping plates 20 will move towards each other after being pressed. When the clamping plates 20 and the limiting grooves 21 are out of the clamping state, the connecting sleeve 3 can be pulled upward to separate the atomizer assembly 7 from the connecting sleeve 3. Since the atomizer assembly 7 is clamped in the support seat 8, the top and bottom of the clamping block 72 are arc-shaped concave, and the liquid guide seat body 71 can be held and pulled upward to separate the atomizer 10 from the battery rod 1, so that the contact block 18 is separated from the conductive column 17, and the battery rod 1, the connecting sleeve 3 and the atomizer assembly 7 can be separated.

The atomizing assembly 7 and the clamping seat 6 are sleeved through the connecting sleeve 3, so that the magnetic block 15 contacts the groove body set in the connecting sleeve 3, and at the same time, the connecting sleeve 3 is pressed down so that the clamping plate 20 at the bottom of the connecting sleeve 3 is inserted into the limiting groove 21, and the assembly of the atomizing device can be completed.

[0036] In summary:

[0037] By arranging the battery rod 1, the connecting seat body 2, the connecting sleeve 3, the atomizing assembly 7, the liquid guiding seat body 71, the clamping block 72, the clamping groove 9 and the clamping plate 20, when separating the atomizing assembly 7, the clamping plates 20 on the left and right sides of the connecting sleeve 3 can be squeezed, and the two clamping plates 20 will move towards each other by one end after being pressed. When the clamping plates 20 and the limiting grooves 21 are out of the clamping state, the connecting sleeve 3 can be pulled upward to separate the atomizing assembly 7 from the connecting sleeve 3. Since the atomizing assembly 7 is clamped in the supporting seat 8, the top and bottom of the clamping block 72 are arc-shaped concave, and the liquid guiding seat body 71 can be held upward. The atomizer 10 is separated from the battery rod 1 by pulling, so that the contact block 18 is separated from the conductive column 17, and the battery rod 1, the connecting sleeve 3, the atomizer assembly 7 and the atomizer 10 are effectively separated. After the atomized liquid in the oil storage tank 5 is used up, the connecting sleeve 3 can be directly removed and replaced, and the atomizer assembly 7 and the atomizer 10 are retained for continued use until the life span is reached. If the atomizer assembly 7 and the atomizer 10 have reached the life span, they can be removed and replaced, and the connecting sleeve 3 can be retained for continued use, which effectively reduces its use cost and improves the environmental friendliness of the electronic atomization device.
