[0033] Referring to FIGS. 1-2, the electronic cigarette atomizer includes a housing body 100, a cigarette holder 300, and a base 200. The cigarette holder 300 and the base 200 are respectively disposed on the housing body 100.

[0034] Furthermore, a battery bin 110 and a cigarette cartridge bin 120 are disposed in the housing body 100. A battery 130 is detachably disposed in the battery bin 110. A first opening 150 is defined in a first end of the housing body 100. The first opening 150 is communicated with the battery bin 110 and the cigarette cartridge bin 120. A
second opening 160 is defined in a second end of the housing body 100. The second opening 160 is communicated with the cigarette cartridge bin 120.

[0035] The embodiment further provides two first openings 150, one of the two first openings 150 is communicated with the battery bin 110, the other one of the two first openings 150 is communicated with the cigarette cartridge bin 120, and sizes and shapes of the two first openings 150 are inconsistent.

[0036] Of course, in some embodiments, one first opening 150 is provided, and the first opening 150 is simultaneously communicated with the cigarette cartridge bin 120 and the battery bin 110.

[0037] The cigarette holder 300 is disposed at one end, close to the second opening 160, of the housing body 100. When the cigarette holder 300 is disposed on the housing body 100, a channel in the cigarette holder 300 is communicated with the second opening 160.

[0038] The cigarette holder 300 and the housing body 100 are connected through buckles.

[0039] A PCB (Printed Circuit Board) 210 is disposed in the base 200. An ejector pin 220 is disposed on the PCB 210. The ejector pin 220 protrudes out of the base 200.
In addition, a mounting hole 230 is defined on the base 200. A cigarette cartridge 140 is detachably mounted in the mounting hole 230. An air inlet hole 240 is further defined on the base 200.
The air inlet hole 240 is communicated with the mounting hole 230.

[0040] The mounting hole 230 is a threaded through hole, and the cigarette cartridge 140 is detachably connected to the mounting hole 230 in a threaded connection mode.

[0041] Specifically, when the cigarette cartridge 140 is disposed in the mounting hole 230, the cigarette cartridge 140 is in contact with the PCB 210, and the PCB 210 controls opening or closing of the cigarette cartridge 140.

[0042] When the base 200 is disposed at one end, close to the first opening 150, of the housing body 100, the ejector pin 220 is just in contact with the battery 130 in the battery bin 110, and the cigarette cartridge 140 is just located in the cigarette cartridge bin 120.

[0043] During actual use, first detaching the base 200 from the housing body 100, and then connecting an air inlet end of the cigarette cartridge 140 to the mounting hole 230, so that the cigarette cartridge 140 is fixed on the base 200 and is in contact with the PCB 210.
The cigarette cartridge 140 is in contact with the PCB 210 through conventional means, such as through positive and negative elastic needles, which is not described in details herein. Then, extending the cigarette cartridge 140 into the cigarette cartridge bin 120 in the housing body 100, and the base 200 is connected to the housing body 100 to complete .. installation or replacement of the cigarette cartridge 140.

[0044] When a user inhales, external airflow sequentially enters the cigarette cartridge 140 through the air inlet hole 240 and the mounting hole 230, and smoke generated in the cigarette cartridge 140 is sucked by the user along with the airflow through the second opening 160 and the cigarette holder 300.

[0045] According to the electronic cigarette atomizer, the base 200 and the housing body 100 are detachably disposed, and the mounting hole 230 is defined on the base 200 to detachably mount the cigarette cartridge 140, so as to fix the cigarette cartridge 140. The cigarette cartridge bin 120 is disposed in the housing body 100 to contain the cigarette cartridge 140, so as to hidden and protect the cigarette cartridge 140.
Therefore, according to above mode, the cigarette cartridge 140 is fixed through the base 200, and the cigarette cartridge 140 is protected through the housing body 100, so that the cigarette cartridge 140 =
is conveniently replaced and is further prevented from falling off.

[0046] Furthermore, a detachable connection between the housing body 100 and the base 200 is specifically achieved by providing a magnet on the housing body 100 and/or the base 200, where the magnet is not shown in the figures. The base 200 is detachably connected to the housing body 100 through the magnet, so that the base 200 is more convenient to disassemble.

[0047] Of course, in other embodiments, the base 200 and the housing body 100 are further detachably connected through threads or buckles.

[0048] Referring to FIG. 2, a cavity is defined in the base 200, and the cavity is respectively communicated with the air inlet hole 240 and the mounting hole 230.

[0049] It can be understood that an interior of the base 200 is made into a cavity structure, on one hand, the PCB 210 is convenient to accommodate, on the other hand, the air inlet hole 240 is convenient to communicate with the mounting hole 230, and an air channel does not need to be additionally disposed. The air inlet hole 240 and the mounting hole 230 are connected only through a structure such as the gap between the PCB 210 and an inner wall of the base 200, which makes structure of the whole base 200 simpler.

[0050] Furthermore, the electronic cigarette atomizer further includes a microphone 250.
The microphone 250 is disposed in the cavity. The microphone 250 is electrically connected to the PCB 210. The microphone 250 is configured to sense airflow entering the air inlet hole 240.

[0051] When the user sucks, the external airflow enters the cavity through the air inlet hole 240, and after the microphone 250 senses the airflow, the PCB 210 controls the cigarette cartridge 140 to work.

[0052] Furthermore, a mounting groove 260 is defined in the cavity of the base 200. The microphone 250 is disposed in the mounting groove 260. An air outlet hole 270 is defined on the base 200. The air outlet hole 270 is communicated with the mounting groove 260.

When the base 200 is disposed on the housing body 100, the air outlet hole 270 is communicated with the first opening 150 with respect to the cigarette cartridge bin 120.

[0053] Specifically, a part of the airflow entering from the air inlet hole 240 is discharged out of the base 200 from the air outlet hole 270 after passing through the microphone 250 and enters the first opening 150, and other airflow enters the cigarette cartridge 140 through the mounting hole 230.

[0054] In addition, when the cigarette cartridge 140 is located in the cavity of the cigarette cartridge 140, a gap 170 is reserved between a side wall of the cigarette cartridge 140 and an inner wall of the cigarette cartridge bin 120. The gap 170 is communicated with the first opening 150 and the second opening 160.

[0055] Specifically, the part of the airflow entering the air inlet hole 240 is discharged out of the base 200 from the air outlet hole 270 after passing through the microphone 250 and enters the gap 170 through the first opening 150, and then the part of the airflow is discharged through the second opening 160. The other airflow enters the cigarette cartridge 140 through the mounting hole 230. Smoke generated in the cigarette cartridge 140 is discharged through the second opening 160. Size and structure of the gap 170 are not limited herein, and the gap 170 only needs to Meet requirements that the airflow can pass through.

[0056] It can be seen that, in the mode, the gap 170 is defined between the cigarette cartridge 140 and the inner wall of the cigarette cartridge bin 120 to enable the airflow to pass through, so that atomizing airflow 400 passing through the cigarette cartridge 140 and switch airflow 500 passing through the microphone 250 respectively flow out from two independent airflow channels. According to the mode, after the air channel in the cigarette cartridge 140 is blocked by the tobacco tar, the switch airflow 500 of the microphone 250 still flows out from the channel of the switch airflow 500 generated by the gap 170, so that the microphone 250 further senses the airflow, and then the PCB 210 still controls the cigarette cartridge 140 to work to atomize the tobacco tar to open the blocked channel. In other words, the mode well ensures that the cigarette cartridge 140 cannot be blocked by the tobacco tar, and the atomizer will not stop working after the air channel in the cigarette cartridge 140 is blocked by the tobacco tar.

[0057] Furthermore, in order to enable the airflow discharged by the air outlet hole 270 to enter the gap 170 and guarantee smoothness of the switch airflow 500. An extending portion opening 180 is further extended to one side of a position, with respect to the cigarette cartridge bin 120, of the first opening 150. The extending portion opening 180 is communicated with the cigarette cartridge bin 120.

[0058] Specifically, when the base 200 is disposed on the housing body 100, the air outlet hole 270 is communicated with the extending portion opening 180, and the airflow exhausted by the air outlet hole 270 enters the gap 170 through the extending portion opening 180.

[0059] Referring to FIG. 2, the housing body 100 includes a support 190a and a housing 190b. The battery bin 110 and the cigarette cartridge bin 120 are respectively disposed on the support 190a. The housing 190b is sleeved on the support 190a, and the housing 190b is configured to surround the support 190a.

[0060] According to the above mode, the housing body 100 is divided into the independent support 190a and the independent housing 190b, on one hand, processing of structures such as the battery bin 110, a cabin of the cigarette cartridge 140, the first opening 150, and the second opening 160 are facilitated, and on the other hand, integrity of the housing body 100 with the cigarette holder 300 and the base 200 after installation is guaranteed.

[0061] Furthermore, the cigarette cartridge bin 120 and/or the battery bin 110 are disposed as semi-surrounding structures. On one hand, the semi-surrounding structures facilitate formation of the gap 170, and on the other hand, the semi-surrounding structures facilitate installation of the battery 130. Meanwhile, the semi-surrounding structures enable the battery bin 110 and the cigarette cartridge bin 120 to be compatible with the batteries 130 or the cigarette cartridges 140 of different sizes and models.

[0062] Referring to FIG. 2, a sealing ring 280 is disposed on an outer wall of the base .. 200. When the base 200 is disposed on the housing body 100, the sealing ring 280 is located between the outer wall of the base 200 and an inner wall of the housing 190b, which plays a role in sealing a joint of the base 200 and the housing body 100, prevents oil leakage and prevents water or other impurities from entering the cavity. And the sealing ring 280 is located between the outer wall of the base 200 and the inner wall of the housing 190b, which plays a role in horizontally extruding the sealing ring 280, and improves sealing effects.

[0063] Referring to FIG. 2, a charging port 290a and/or a key 290b are further disposed on the base 200. The charging port 290a and/or the key 290b are respectively electrically connected to the PCB 210.
