At the same time, since the liquid storage chamber is connected to the liquid storage cotton through the liquid outlet hole of the porous structure, under normal pressure, the liquid will form a certain liquid seal structure at the liquid outlet hole to prevent the liquid in the liquid storage chamber from flowing unimpeded to the liquid storage cotton. In addition, when the liquid storage chamber is filled with liquid, the amount of liquid filled into the liquid storage chamber by the liquid filling device is set according to the volume of the liquid storage chamber and the volume of the liquid storage cotton, so that when the liquid filling operation is completed, the liquid storage cotton is in a semi-wet state, thereby ensuring that the liquid storage cotton maintains sufficient liquid absorption capacity.

It can be seen that this technical solution can effectively improve the existing electronic atomizer, which is prone to leakage in the liquid storage chamber due to vibration, air pressure changes, etc. during transportation, affecting the user's experience.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0037] In one embodiment, Figure 1As shown, the embodiment of the present application also provides a liquid injection method, which may specifically include the following steps:

[0038] Step S110: providing a semi-finished atomizer, wherein the semi-finished atomizer has an air flow channel, liquid storage cotton and a liquid storage cavity built therein, the liquid storage cotton is arranged around the air flow channel, the liquid storage cavity is arranged around the liquid storage cotton and the air flow channel, and the liquid storage cavity is provided with a liquid outlet hole connected to the liquid storage cotton.

[0039] It can be understood that the liquid injection method of the embodiment of the present method is specifically applied to the liquid injection operation in the production process of the electronic atomizer 1, wherein the electronic atomizer 1 is the main component of the electronic atomizer device. The electronic atomizer device generally includes, in addition to the electronic atomizer 1, a power supply body for powering the electronic atomizer 1, so that the electronic atomizer device can store liquid through the electronic atomizer 1, and under the power supply of the power supply body, the stored liquid (specifically, it can be an atomized liquid such as tobacco oil) is converted into an aerosol and sprayed out through the airflow channel 111 for the user to inhale.

[0040] For this reason, Figures 2 to 6 As shown, in order to complete the corresponding liquid injection operation, it is necessary to first provide a semi-finished atomizer (i.e., the part of the electronic atomizer shown in the figure except the bottom cover assembly, the sealing rubber stick and the sealing rubber plug). The semi-finished atomizer is mainly assembled through the assembly process of the electronic atomizer 1 before liquid injection. The assembly process mainly completes the assembly of the shell assembly 100 and the atomization assembly 200 of the electronic atomizer 1 to obtain a semi-finished atomizer with an air flow channel 111, a liquid storage cotton 120 and a liquid storage cavity 112. At the same time, the liquid storage cotton 120 is arranged around the air flow channel 111, and the liquid storage cavity 112 is arranged around the liquid storage cotton 120 and the air flow channel 111. The liquid storage cavity 112 is provided with a liquid outlet 113 connected to the liquid storage cotton 120.

[0041] Generally speaking, the liquid storage cotton 120 mentioned above is generally specially treated organic cotton, which has good liquid absorption and liquid conductivity, and can effectively absorb the liquid in the liquid storage cavity 112 and ensure the atomization effect. In addition, materials such as bamboo charcoal cotton can also be used as a substitute to enhance the suction taste of the electronic atomizer 1 and reduce odors. The liquid storage cavity 112 mentioned above is provided with a liquid outlet 113 connected to the liquid storage cotton 120, which specifically means that the liquid outlet 113 is arranged on the side away from the liquid storage cavity 112, so that the liquid storage cotton 120 completely covers the liquid outlet 113 on the outside of the liquid storage cavity 112.

[0042] In addition, the above-mentioned airflow channel 111 is also provided with an atomizer assembly 200, which can be specifically installed at one end of the airflow channel 111 adjacent to the liquid outlet hole 113 and be in liquid communication with the liquid storage cotton 120, so as to heat and atomize the liquid transported by the liquid storage cotton 120 to form an aerosol. The above-mentioned atomizer assembly 200 can be specifically installed at one end of the airflow channel 111 adjacent to the liquid outlet hole 113, which specifically means that the atomizer assembly 200 is installed in the airflow channel 111 and is arranged adjacent to the liquid outlet hole 113, so that the liquid in the liquid storage cavity 112 is guided to the liquid storage cotton 120 through the liquid outlet hole 113, and then can quickly flow into the atomizer assembly 200 through the diversion of the liquid storage cotton 120. The above-mentioned liquid connection between the atomizer component 200 and the liquid storage cotton 120 specifically refers to that the air flow channel 111 can be provided with a corresponding liquid guide port 114, so that the atomizer component 200 can contact the liquid storage cotton 120 through the liquid guide port 114, so that the liquid in the liquid storage cotton 120 can flow into the atomizer component 200, so that the atomizer component 200 remains in a moist or semi-moist state. In this way, since the atomizer component 200 always maintains liquid connection with the liquid storage cotton 120, there will be no delay in the outflow of liquid of part of the product when the product is first used, resulting in dry burning and other phenomena that affect the atomization effect of the atomizer component 200.

[0043] Step S120: providing a liquid injection device, performing a liquid injection operation on the liquid storage chamber through the liquid injection device, and setting the liquid injection amount of the liquid storage chamber according to the volume of the liquid storage chamber and the volume of the liquid storage cotton, so that when the liquid injection operation is completed, the liquid storage cotton is in a semi-wet state.

[0044] It is understandable that if Figures 2 to 6 As shown, after the semi-finished atomizer is obtained through the above method steps, a liquid injection device (not shown) can be further provided to perform liquid injection operation on the liquid storage chamber 112, and the liquid injection amount of the liquid storage chamber 112 by the liquid injection device is set according to the volume of the liquid storage chamber 112 and the volume of the liquid storage cotton 120, so that when the liquid injection operation is completed, the liquid storage cotton 120 is in a semi-wet state.

[0045] Generally speaking, the injection device mentioned above can be an automated injection device or a manual injection syringe, and the injection volume can be set in advance before the injection, so that during the injection process, the corresponding injection operation can be performed according to the corresponding injection volume.

[0046] In this way, through the above method steps, since the liquid storage cotton 120 is arranged between the liquid storage chamber 112 and the air flow channel 111, the liquid coming out of the liquid storage chamber 112 through the liquid outlet hole 113 will first pass through the liquid storage cotton 120 and then reach the atomization component 200 of the air flow channel 111. At the same time, since the liquid storage chamber 112 is connected to the liquid storage cotton 120 through the liquid outlet hole 113 of the porous structure, under normal pressure, the liquid will form a certain liquid seal structure at the liquid outlet hole 113 to prevent the liquid in the liquid storage chamber 112 from flowing unimpeded to the liquid storage cotton 120. In addition, when the liquid storage chamber 112 is injected, the injection amount of the liquid storage chamber 112 by the injection device is set according to the volume of the liquid storage chamber 112 and the volume of the liquid storage cotton 120, so that when the injection operation is completed, the liquid storage cotton 120 is in a semi-wet state, thereby ensuring that the liquid storage cotton 120 maintains sufficient liquid absorption capacity. In this way, during the transportation of the electronic atomizer 1, even if the liquid storage chamber 112 leaks due to vibration, air pressure changes, etc., the semi-wet liquid storage cotton 120 can absorb the leaked liquid in time to avoid the impact of the leakage on the user's experience, which can greatly improve the user's experience.

[0047] In some examples, such as Figures 2 to 6 As shown, the liquid storage cotton 120 is in a semi-wet state, specifically, the end of the liquid storage cotton 120 away from the liquid outlet 113 has a dry part of a preset length, so that it can be ensured that the end of the liquid storage cotton 120 away from the liquid outlet 113 is not completely wetted by the liquid, so as to ensure that the liquid storage cotton 120 can maintain sufficient liquid absorption capacity to promptly absorb the liquid leakage caused by vibration, air pressure change, etc. during the transportation of the liquid storage cavity 112. Further, the preset length is 1 to 2 mm, so that the liquid storage cotton 120 can maintain sufficient liquid absorption capacity through this parameter design, and the atomization component 200 can better maintain the above-mentioned wet or semi-wet state.

[0048] In some examples, such as Figures 2 to 6 As shown, the specific process of executing the above method step "setting the injection amount of the liquid storage chamber by the injection device according to the volume of the liquid storage chamber and the volume of the liquid storage cotton" is as follows: the injection amount of the liquid storage chamber 112 by the injection device is set to the sum of the volume of the liquid storage chamber 112 and the preset volume, and the preset volume is 0.4 to 0.7 times the volume of the liquid storage cotton 120. In this way, by setting the above injection amount, it can be ensured that after the injection is completed, the liquid storage cotton 120 can be set in a preset semi-wet state, so that the liquid storage cotton 120 can maintain sufficient liquid absorption capacity while allowing the atomization component 200 to better maintain the above-mentioned wet or semi-wet state.

[0049] In some examples, such as Figure 3 and Figure 4As shown, the aperture of the liquid outlet hole 113 is 0.7mm to 1.0mm. In this way, by setting the aperture size, the liquid can better form a corresponding liquid seal structure at the liquid outlet hole 113 under normal pressure to prevent the liquid in the liquid storage chamber 112 from flowing to the liquid storage cotton 120 without obstacles, which can further ensure the sealing effect of the liquid storage chamber 112 under certain conditions. Further, the liquid storage chamber 112 is provided with a plurality of liquid outlet holes 113, and the plurality of liquid outlet holes 113 are arranged around the liquid storage cotton 120. In this way, through the above-mentioned structural setting, when the user inhales the electronic atomizer 1, the liquid storage chamber 112 can flow the liquid in the cavity into the liquid storage cotton 120 evenly through the plurality of liquid outlet holes 113, so that the liquid storage cotton 120 has the same amount of liquid absorption in the circumferential direction of the air flow channel 111, thereby making the liquid flow of the liquid storage cotton 120 guiding the atomization assembly 200 always remain stable, and finally, ensure that the electronic atomizer 1 has a consistent suction taste to enhance the user experience.

[0050] It can be understood that the shape of the liquid outlet hole 113 in this example includes but is not limited to a circular hole structure or a square hole structure. Generally, a circular hole structure is preferably used because, compared with liquid outlet holes 113 of other shapes, the liquid outlet hole 113 of a circular hole structure can not only ensure the stable and uniform liquid discharge of the liquid outlet hole 113, but also can better form a corresponding liquid sealing structure under normal pressure to ensure the sealing effect of the liquid storage chamber 112 under certain conditions. Generally speaking, when the liquid outlet hole 113 is a circular hole structure, the aperture of the liquid outlet hole 113 can be specifically the diameter of the circular hole structure, and when the liquid outlet hole 113 is a square hole structure, the aperture of the liquid outlet hole 113 can be specifically the diameter of the circumscribed circle of the square hole structure.

[0051] In some examples, such as Figure 3 and Figure 4As shown, at least one liquid guide port 114 is provided on the peripheral side wall of one end of the air flow channel 111 adjacent to the liquid outlet 113, and each liquid guide port 114 is connected to the liquid storage cotton 120, and the atomizer assembly 200 blocks all the liquid guide ports 114, so that the atomizer assembly 200 is in liquid communication with the liquid storage cotton 120. In this way, through the above-mentioned structural setting, the atomizer assembly 200 can contact the liquid storage cotton 120 through the liquid guide hole, so that the liquid in the liquid storage cotton 120 can flow into the atomizer assembly 200, so that the atomizer assembly 200 remains in a wet or semi-wet state. In this way, since the atomizer assembly 200 always maintains liquid communication with the liquid storage cotton 120, there will be no lag in the outflow of liquid of some products when the product is first used, resulting in dry burning and other phenomena that affect the atomization effect of the atomizer assembly 200. Furthermore, the atomization assembly 200 includes a liquid-conducting cotton and a heating element, the liquid-conducting cotton covers all the liquid-conducting ports 114, and the heating element is mounted on the liquid-conducting cotton. Thus, through the above-mentioned structural arrangement, it is ensured that the liquid-conducting cotton can be better connected to the liquid storage cotton 120 for liquid, while the heating element can better heat and atomize the liquid in the liquid-conducting cotton as a whole, so as to enhance the atomization effect of the atomization assembly 200. Furthermore, a plurality of liquid-conducting ports 114 are evenly spaced on the peripheral side wall of one end of the air flow channel 111 adjacent to the liquid outlet 113. Thus, through the above-mentioned structural arrangement, it can be ensured that the liquid in the liquid storage cotton 120 penetrates more evenly into the liquid-conducting cotton of the entire atomization assembly 200, so as to further enhance the atomization effect of the atomization assembly 200.

[0052] It is understandable that the liquid-conducting cotton in this example can be made of the same material as the liquid-storing cotton 120 to ensure that it can effectively absorb the liquid in the liquid-storing cotton 120 and ensure the atomization effect. The shape of the liquid-conducting port 114 in this example includes but is not limited to a round port structure or a square port structure.

[0053] In some examples, such as Figure 3 and Figure 4 As shown, the housing assembly 100 includes a housing 110 having an air flow channel 111 and a base 130. The housing 110 is further provided with a first annular groove body (not shown in the figure) and a second annular groove body (not shown in the figure). The first annular groove body is arranged around the air flow channel 111 for arranging the liquid storage cotton 120. The second annular groove body is arranged around the first annular groove body and the air flow channel 111, so that when the base 130 is arranged at the first end of the housing 110, the base 130 is surrounded to form a liquid storage cavity 112. In this way, through the above-mentioned structural arrangement, it can better arrange and fix the liquid storage cotton 120 while ensuring that the liquid storage cotton 120 is arranged around the air flow channel 111, and the liquid storage cavity 112 is arranged around the liquid storage cotton 120 and the air flow channel 111.

[0054] It can be understood that the first annular groove body and the air flow channel 111 in this example have a common first side wall, and the above-mentioned liquid guide port 114 can be specifically opened on the first side wall. The first annular groove body and the second annular groove body in this example have a common second side wall, and the above-mentioned liquid outlet 113 can be specifically opened on the first side wall.

[0055] In some examples, such as Figures 2 to 6 As shown, a liquid injection blind hole 131 is provided at one end of the liquid storage chamber 112 away from the outlet 115 of the air flow channel 111 (specifically, the base 130), and the liquid outlet hole 113 is provided adjacent to the liquid injection blind hole 131. At this time, the process of performing the above method step of "injecting liquid into the liquid storage chamber by the liquid injection device" is as follows: after the liquid injection blind hole 131 is arranged upward, the liquid injection needle of the liquid injection device is inserted into the liquid storage chamber 112 through the liquid injection blind hole 131 to perform the liquid injection operation. In this way, through the above-mentioned structural setting, when the liquid storage chamber 112 of the electronic atomizer 1 needs to be filled with liquid, the injection needle of the injection device can be extended from top to bottom into the liquid storage chamber 112 through the injection blind hole 131, so as to better complete the injection operation of the liquid storage chamber 112. At the same time, after the liquid storage chamber 112 is basically filled with liquid, the liquid in the liquid storage chamber 112 will overflow and flow to the liquid storage cotton 120, so that the liquid storage cotton 120 maintains the above-mentioned semi-wet state. In this way, the above-mentioned injection amount setting can be used to more accurately ensure that after the injection is completed, the liquid storage cotton 120 can be set in a preset semi-wet state, so that the liquid storage cotton 120 can maintain sufficient liquid absorption capacity while allowing the atomization component 200 to better maintain the above-mentioned wet or semi-wet state.

[0056] In one embodiment, Figure 7 As shown, the embodiment of the present application also provides an assembly method of an electronic atomizer, and the assembly method may specifically include the following steps:

[0057] Step S210: providing a semi-finished atomizer product, and performing the liquid injection method in the above embodiment on the semi-finished atomizer product to obtain a preliminary finished atomizer product.

[0058] Step S220: providing a bottom cover assembly and a sealing rubber plug, and installing the bottom cover assembly and the sealing rubber plug on the preliminary finished atomizer product, respectively, to obtain a target electronic atomizer.

[0059] It can be understood that based on the above embodiments, Figures 2 to 6 As shown, when the liquid injection operation of the semi-finished atomizer is completed by executing the liquid injection method in the above embodiment on the semi-finished atomizer and the preliminary finished atomizer is obtained, a bottom cover assembly 300 and a sealing plug 500 can be further provided, and the bottom cover assembly 300 and the sealing plug 500 are respectively installed on the preliminary finished atomizer to obtain the target electronic atomizer 1.

[0060] In this way, through the above method steps, the assembled electronic atomizer 1, since its liquid storage cotton 120 is arranged between the liquid storage chamber 112 and the air flow channel 111, the liquid coming out of the liquid storage chamber 112 through the liquid outlet hole 113 will first pass through the liquid storage cotton 120 and then reach the atomization component 200 of the air flow channel 111. At the same time, since the liquid storage chamber 112 is connected to the liquid storage cotton 120 through the liquid outlet hole 113 of the porous structure, under normal pressure, the liquid will form a certain liquid seal structure at the liquid outlet hole 113 to prevent the liquid in the liquid storage chamber 112 from flowing unimpeded to the liquid storage cotton 120. In addition, when the liquid storage chamber 112 is injected, the amount of liquid injected into the liquid storage chamber 112 by the injection device is set according to the volume of the liquid storage chamber 112 and the volume of the liquid storage cotton 120, so that when the injection operation is completed, the liquid storage cotton 120 is in a semi-wet state, thereby ensuring that the liquid storage cotton 120 maintains sufficient liquid absorption capacity. In this way, during the transportation of the electronic atomizer 1, even if the liquid storage chamber 112 leaks due to vibration, air pressure changes, etc., the semi-wet liquid storage cotton 120 can absorb the leaked liquid in time to avoid the leakage affecting the user's experience, which can greatly improve the user's experience.

[0061] In some examples, such as Figures 2 to 6 As shown, the liquid storage cavity 112 is provided with a liquid injection blind hole 131, and a column 311 is convexly provided on one side of the bottom cover assembly 300. At this time, the specific process of installing the bottom cover assembly 300 on the preliminary finished product of the atomizer is as follows: the side of the bottom cover assembly 300 provided with the column 311 is installed on the preliminary finished product of the atomizer, and the column 311 is plugged and matched with the liquid injection blind hole 131 to seal the liquid injection blind hole 131. In this way, through the above-mentioned structural setting, when the liquid storage cavity 112 of the electronic atomizer 1 needs to be injected, the injection needle of the injection device can be extended into the liquid storage cavity 112 through the injection blind hole 131 to complete the corresponding injection operation. At the same time, when the liquid injection is completed, the electronic atomizer 1 can be assembled through the bottom cover assembly 300 so that the column 311 on the bottom cover assembly 300 is plugged into and matched with the liquid injection blind hole 131 to seal the liquid injection blind hole 131, thereby ensuring that during the transportation, storage or use of the electronic atomizer 1, the liquid in the liquid storage chamber 112 will no longer flow out through the liquid injection blind hole 131.

[0062] In some examples, such as Figure 5 and Figure 6As shown, the bottom cover assembly 300 includes a bottom cover body 310 and an electrode module 320, a column 311 is convexly arranged on one side of the bottom cover body 310, and the electrode module 320 is arranged through the bottom cover body 310 and is electrically connected to the atomization assembly 200. It can be understood that the electrode module 320 may specifically include two electrodes, and the two electrodes are respectively embedded and assembled on the bottom cover body 310, and have a portion exposed on the outer surface of the bottom cover body 310, so as to facilitate its electrical connection with the power supply body. In this way, through the above-mentioned structural arrangement, when the electronic atomizer 1 is assembled on the corresponding power supply body, it can be electrically connected to the power supply body through the electrode assembly, so that under the operation of the power supply body, the heating element of the atomization assembly 200 heats the liquid-conducting cotton to convert the liquid in the liquid-conducting cotton into an aerosol spray for the user to inhale.

[0063] In some examples, such as Figures 2 to 6 As shown, the electronic atomizer 1 also includes a sealing glue stick 400, and a detachable sealing portion 410 is provided at one end of the sealing glue stick 400. The base 130 is provided with an inlet 116 of the airflow channel 111, and the bottom cover body 310 is provided with a sealing glue stick through hole 312, and the sealing glue stick through hole 312 is arranged opposite to the inlet 116 of the airflow channel 111 in the extension direction of the airflow channel 111. After one end of the sealing glue stick 400 having the sealing portion 410 passes through the sealing glue stick through hole 312, the inlet 116 of the airflow channel 111 is sealed by the sealing portion 410. In this way, through the above-mentioned structural arrangement, when the electronic atomizer 1 is in a transportation or storage state, it can seal the inlet 116 of the airflow channel 111 through the sealing portion 410 of the sealing glue stick 400 to ensure that the liquid in the airflow channel 111 will not flow out through the inlet 116 of the airflow channel 111, so as to avoid leakage here. When the electronic atomizer 1 is used for suction, the sealing glue stick 400 can be pulled to make it in a Figure 4 In the state shown, the sealing portion 410 is no longer located at the inlet 116 of the airflow channel 111, but is located at the sealing rod perforation 312, sealing the sealing rod perforation 312, so that the inlet 116 of the airflow channel 111 can be connected to the outside through other air inlet holes 313 opened on the bottom cover body 310. At this time, since the sealing rod perforation 312 directly opposite to the inlet 116 of the airflow channel 111 is sealed by the sealing portion 410, during the suction process of the electronic atomizer 1, condensate formed in the airflow channel 111 will not directly leak out through the sealing rod perforation 312.

[0064] It is understood that the sealant stick 400 in this example further includes a gripping portion 420, and the gripping portion 420 is detachably connected to the sealing portion 410, that is, the gripping portion 420 and the sealing portion 410 are connected by a breakable connecting piece. Figure 3In the state shown, the connecting piece can be broken to separate the holding portion 420 from the sealing portion 410. The sealing portion 410 remains in the electronic atomizer 1 to seal the sealing rod perforation 312. The holding portion 420 can be discarded to avoid the protrusion of the holding portion 420 affecting the normal assembly of the electronic atomizer 1.

[0065] In some examples, such as Figure 6 As shown, the sealing rubber plug 500 mentioned above is a T-shaped structure. At this time, the specific process of installing the sealing rubber plug 500 on the preliminary finished product of the atomizer is as follows: insert one end of the sealing rubber plug 500 extending along the extension direction of the airflow channel 111 into the airflow channel 111, so as to install the sealing rubber plug 500 on the preliminary finished product of the atomizer, and make the sealing rubber plug 500 seal the outlet 115 of the airflow channel 111. In this way, through the above-mentioned structural setting, the sealing performance at the outlet 115 of the airflow channel 111 can be ensured by the sealing rubber plug 500 tightly sealing the outlet 115 of the airflow channel 111, so as to avoid leakage at this place during product transportation.

[0066] It can be understood that the outlet 115 of the airflow channel 111 mentioned in this example is generally arranged in a funnel-shaped structure, that is, the outlet 115 may specifically include an arcuate groove body portion and an air pipe portion, the arcuate groove body portion is recessed in the end surface of the second end of the housing 110, and one end of the air pipe portion is connected to the groove bottom of the arcuate groove body portion and is connected to form the outlet 115. At this time, the other end of the air pipe portion can be connected through the airflow channel 111. In this way, the flow mode of the aerosol near the outlet 115 can be effectively optimized through the above-mentioned structural arrangement to provide the user with a softer and more comfortable suction taste. Accordingly, since the sealing rubber plug 500 in this example is specifically arranged in a T-shaped structure, it can better fit the outlet 115 of the funnel-shaped airflow channel 111 to further ensure the sealing performance at the outlet 115 of the airflow channel 111, so as to further avoid leakage here during product transportation.

[0067] In one embodiment, Figures 2 to 6 As shown, an embodiment of the present application further provides an electronic atomizer, which is assembled by the assembly method in the above embodiment.

[0068] In this way, the electronic atomizer provided in the embodiment of the present application, through the above-mentioned structural arrangement, has a liquid storage cotton 120 arranged between the liquid storage chamber 112 and the air flow channel 111, so that the liquid coming out of the liquid storage chamber 112 through the liquid outlet hole 113 will first pass through the liquid storage cotton 120 and then reach the atomization component 200 of the air flow channel 111. At the same time, since the liquid storage chamber 112 is connected to the liquid storage cotton 120 through the liquid outlet hole 113 of the porous structure, under normal pressure, the liquid will form a certain liquid seal structure at the liquid outlet hole 113 to prevent the liquid in the liquid storage chamber 112 from flowing unimpeded to the liquid storage cotton 120. In addition, when the liquid storage chamber 112 is filled with liquid, the amount of liquid filled into the liquid storage chamber 112 by the filling device is set according to the volume of the liquid storage chamber 112 and the volume of the liquid storage cotton 120, so that when the filling operation is completed, the liquid storage cotton 120 is in a semi-wet state, thereby ensuring that the liquid storage cotton 120 maintains sufficient liquid absorption capacity. In this way, during the transportation of the electronic atomizer 1, even if the liquid storage chamber 112 leaks due to vibration, air pressure changes, etc., the semi-wet liquid storage cotton 120 can absorb the leaked liquid in time to avoid the leakage affecting the user's experience, which can greatly improve the user's experience.

[0069] It is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present application.
