Typically, a small portion of the liquid inside the atomizer 11 will leak out of the atomizer 11 to form a leakage, which will drip into the sensing channel 613 along the path indicated by the dashed arrow in fig. 4.

Referring to fig. 4 and 12, in some embodiments, the mounting frame 300 is disposed inside the housing 650, and the mounting frame 300 and the housing 650 are opened with the accommodating chamber 500, such that a majority of the accommodating chamber 500 is located on the mounting frame 300 and a minority of the accommodating chamber 500 is located on the housing 650. The mounting bracket 300 further has a mounting cavity 310, and the mounting cavity 310 is used for accommodating the battery 640.

Referring to fig. 3 and 5, in some embodiments, the supporting frame 100 may be detachably disposed in the accommodating cavity 500, for example, the supporting frame 100 may be connected to the inner wall surface of the accommodating cavity 500 by a snap connection, a magnetic connection, an elastic press connection, or a push-push connection, as long as the supporting frame 100 can be taken out of the accommodating cavity 500 from the connection between the housing 650 and the mounting bracket 300.

Referring to fig. 10 and 11, the supporting bracket 100 includes a bottom plate 120, an end plate 130, side plates 140, and a baffle plate 150, where the number of the bottom plate 120 and the number of the short plates are both one, the number of the side plates 140 and the number of the baffle plate 150 are both two, the short plates are connected to one end of the bottom plate 120 in the width direction, one of the side plates 140 is connected to one end of the bottom plate 120 in the length direction, and the other side plate 140 is connected to the other end of the bottom plate 120 in the length direction. One of the side plates 140 is connected to one end of the end plate 130, and the other side plate 140 is connected to the other end of the end plate 130. One of the blocking plates 150 is connected to one end of one of the side plates 140 away from the end plate 130 in a bending manner, and the other blocking plate 150 is connected to one end of the other side plate 140 away from the end plate 130 in a bending manner, for example, the blocking plates 150 and the side plates 140 may be perpendicular to each other. The bottom plate 120, the end plate 130, the side plate 140 and the baffle 150 enclose a first cavity 111, the two baffles 150 and the bottom plate 120 enclose a second cavity 112, the cross-sectional dimension of the first cavity 111 is larger than that of the second cavity 112, and the first cavity 111 and the second cavity 112 form an open cavity 110. The open cavity 110 may be considered to be formed by a portion of the outer surface of the support frame 100 being recessed by a set depth in the thickness direction of the support frame 100 during the manufacturing process.

The reservoir 200 may be made of a cotton material so that the pores in the reservoir 200 can absorb and store a large amount of liquid. The reservoir member 200 includes a first reservoir portion 210 and a second reservoir portion 220, the second reservoir portion 220 being connected to an end surface of the first reservoir portion 210, the second reservoir portion 220 protruding a certain height relative to the end surface, the first reservoir portion 210 having a cross-sectional dimension larger than the second reservoir portion 220. The first reservoir 210 is sized to fit the first cavity 111 such that the first reservoir 210 can be fully received in the first cavity 111; the second reservoir 220 is sized to fit the second cavity 112 such that a portion of the second reservoir 220 is received in the second cavity 112 and another portion of the second reservoir 220 is received in the rear cavity 520 of the receiving cavity 500.

After the first liquid storage part 210 is installed in the first cavity 111 along the thickness direction of the support frame 100, the two side plates 140 form a clamping and limiting effect on the first liquid storage part 210 along the length direction of the bottom plate 120, and meanwhile, the end plate 130 and the two baffle plates 150 form a clamping and limiting effect on the first liquid storage part 210 along the width direction of the bottom plate 120, so that the liquid storage part 200 is prevented from shifting relative to the support frame 100, and the stability and reliability of the installation of the whole liquid storage part 200 on the support frame 100 are improved.

The end plate 130 has a mounting face 131, the mounting face 131 bounding a portion of the first cavity 111 such that the mounting face 131 is abuttable with the first reservoir 210. The mounting surface 131 is recessed to form a see-through hole 131a, and obviously, the see-through hole 131a communicates with the first cavity 111. The end plate 130 includes a see-through portion 132, the see-through portion 132 may be a flat plate structure, the see-through portion 132 covers one end of the see-through hole 131a away from the first cavity 111, and the see-through hole 131a is isolated from the outside by the effect of the see-through portion 132, so as to prevent external dust and liquid from entering the first cavity 111 through the see-through hole 131a and corroding the oil storage member. When the color of the liquid storage member 200 changes, the user can perceive the color change of the liquid storage member 200 itself through the see-through portion 132 and the see-through hole 131 a. The see-through portion 132 may be relatively thin in thickness so that the color change of the reservoir 200 is more clearly and prominently presented to the user.

Referring to fig. 7, 8 and 9, after the supporting frame 100 carrying the liquid storage device 200 is installed in the accommodating cavity 500, that is, after the supporting frame 100 moves relative to the housing 650 and the mounting frame 300 and is inserted into the accommodating cavity 500, the supporting frame 100 is completely matched with the front cavity 510 of the accommodating cavity 500, the end of the second liquid storage portion 220 is located in the rear cavity 520 of the accommodating cavity 500, and the end of the supporting frame 100 abuts against the abutting plate 630, so that the supporting frame 100 cannot move relative to the accommodating cavity 500. Therefore, the limiting function of the abutting plate 630 can play a role in prompting that the support frame 100 is installed in place on the one hand, and the stability and reliability of the installation of the support frame 100 can be improved on the other hand. While the opening of the open cavity 110 is disposed toward the sealing cover 610, the sealing cover 610 covers the opening of the open cavity 110 in view of the sealing cover 610 closing the portion of the front cavity 510 on the mounting frame 300 and the entire rear cavity 520, so that the sealing cover 610 forms a closing effect on the open cavity 110. The control circuit board 620 is connected to a surface of the sealing cover 610 facing away from the accommodating chamber 500, such that the control circuit board 620 is located outside the accommodating chamber 500 and the open chamber 110. That is, the control circuit board 620 is prevented from being in direct contact with the liquid storage member 200 by the isolation of the sealing cover 610.

When the leaked liquid in the atomizer 11 enters the sensing channel 613 of the sealing cover 610 under the condition that the support frame 100 carrying the liquid storage member 200 is installed in the accommodating cavity 500, the leaked liquid in the sensing channel 613 further drops into the rear cavity 520 of the accommodating cavity 500. Because the tip of the second stock solution portion 220 of the stock solution piece 200 is located in this back cavity 520, this second stock solution portion 220 will play the absorption to the weeping of back cavity 520 to store the weeping of back cavity 520 in whole stock solution piece 200, avoid the weeping to flow out whole holding chamber 500.

When the liquid storage member 200 does not absorb the leakage liquid, the color of the liquid storage member 200 is a first color, and the first color may be white or black, etc. When the liquid storage member 200 is saturated when absorbing the leakage liquid, the color of the liquid storage member 200 is a second color, for example, the second color is a bright and striking red or blue, and the second color is perceived by the user through the see-through hole 131a and the see-through portion 132. Therefore, when the color of the liquid storage member 200 presented by the perspective part 132 is the second color, the user can make a judgment that the liquid storage member 200 has saturated the stored leakage according to the second color. At this time, the connection between the supporting frame 100 and the outer shell 650 and the mounting frame 300 can be released, the supporting frame 100 can be pulled out from the accommodating cavity 500, then the liquid storage member 200 with saturated leakage liquid storage can be unloaded from the supporting frame 100 and discarded, then a new liquid storage member 200 which does not absorb any liquid can be installed in the open cavity 110 of the supporting frame 100, and finally the supporting frame 100 carrying the new liquid storage member 200 can be accommodated in the accommodating cavity 500 again.

If the liquid storage part 200 with saturated leaking liquid cannot be replaced, or if the liquid storage part 200 cannot be replaced in time due to the fact that the saturated leaking liquid cannot be accurately judged, the whole accommodating cavity 500 is filled with the subsequent leaking liquid which cannot be continuously absorbed by the liquid storage part 200 until the leaking liquid flows into the induction channel 613, and then the leaking liquid blocks the induction channel 613, so that the electronic atomization device 10 cannot be normally started due to the fact that the negative pressure in the atomizer 11 cannot be sensed. Moreover, the leaked liquid may overflow from the accommodating cavity 500 and flow into the battery 640, the control circuit board 620, the sensor and other components, so as to corrode the components, and ultimately affect the service life of the electronic atomization device 10.

For the electronic atomizing device 10 of the above embodiment, firstly, the user can determine whether the leaked liquid stored in the liquid storage member 200 is saturated according to the color presented by the perspective portion 132, and then the user can take the support frame 100 out of the accommodating cavity 500, discard the liquid storage member 200 with the saturated leaked liquid storage, replace the liquid storage member 200 with a new liquid storage member 200 with the saturated leaked liquid storage member and accommodate the new liquid storage member 200 in the accommodating cavity 500 along with the support frame 100, so that the new liquid storage member 200 can continuously absorb the leaked liquid. Therefore, through the perception of the second color and the installation and the removal of the support frame 100, the new liquid storage part 200 can be periodically replaced for the liquid storage part 200 with saturated leaked liquid storage. The leakage liquid is prevented from filling the whole accommodating cavity 500 because the liquid storage part 200 cannot continuously absorb the leakage liquid, the leakage liquid is further prevented from blocking the induction channel 613 to influence the normal starting of the electronic atomization device 10, and the leakage liquid can be effectively prevented from overflowing from the accommodating cavity 500 and the induction channel 613 to corrode parts such as the battery 640, the control circuit board 620 and the sensor, so that the service lives of the power supply 12 and the electronic atomization device 10 are prolonged. The risk of explosion of the battery 640 due to liquid leakage corrosion can be reduced, and the safety of the electronic atomization device 10 in the use process is improved. Moreover, the storage part 200 with saturated leakage storage can be periodically replaced by taking the support frame 100 out of the containing cavity 500, so that convenience in leakage cleaning is improved.

In other embodiments, the support stand 100 may be replaced with an opening and closing door, for example, the opening and closing door is rotatably disposed on the housing 650, so that the opening and closing door can open or close the accommodating chamber 500. When the liquid storage part 200 is perceived to be in the second color through the switch door, the switch door can be opened, the liquid storage part 200 with saturated leaked liquid storage is taken out of the accommodating cavity 500, then a new liquid storage part 200 is accommodated in the accommodating cavity 500, and finally the switch door is closed. Therefore, by opening and closing the opening and closing door, the new liquid storage member 200 can be installed in the accommodation chamber 500 in place of the liquid storage member 200 whose leaking liquid has been saturated.

Referring to fig. 5, 6 and 9, the sealing cover 610 may be made of a silicone material, and when the sealing cover 610 seals the accommodating cavity 500 and the opening, since the control circuit board 620 is located outside the accommodating cavity 500, the control circuit board 620 may be prevented from directly contacting the liquid storage element 200 by the sealing and isolating effects of the sealing cover 610, so that the leakage on the liquid storage element 200 may not corrode the control circuit board 620, thereby prolonging the service life of the power supply 12. Meanwhile, the accommodating cavity 500 and the mounting cavity 310 can be isolated from each other by the sealing effect of the sealing cover 610, so that leakage liquid stored in the liquid storage part 200 is prevented from dripping from the accommodating cavity 500 to the mounting cavity 310 to corrode the battery 640, and the service life of the power supply 12 can be prolonged.

Referring to fig. 5 and 11, in some embodiments, the sealing element 400 may be an O-ring, the supporting frame 100 is provided with an annular limiting groove 160, and the sealing element 400 is engaged with the limiting groove 160, such that a portion of the sealing element 400 is completely received in the limiting groove 160, and another portion of the sealing element 400 is located outside the limiting groove 160. After the supporting frame 100 is installed in the accommodating cavity 500, the whole sealing element 400 is pressed between the inner wall surface of the accommodating cavity 500 and the supporting frame 100, so that the sealing element 400 has a sealing effect on the whole accommodating cavity 500, and leakage of liquid in the liquid storage element 200 and the accommodating cavity 500 to the outside of the housing 650 is avoided.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
