[0031] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0032] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "inside", "outside", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0033] See also Figure 1 , Figure 2 and Figure 3The electronic atomization device 10 provided in one embodiment of the present invention includes an atomizer 11 and a power supply 12. The power supply 12 provides electrical energy to the atomizer 11. The atomizer 11 contains an aerosol-generating matrix represented by a liquid. The atomizer 11 can convert the electrical energy into heat, so that the liquid absorbs the heat and atomizes to form an aerosol in the form of smoke. The atomizer 11 and the power supply 12 are detachably connected. Figure 4 and Figure 6 The power supply 12 includes a support frame 100, a liquid storage member 200, a mounting frame 300, a sealing member 400, a sealing cover 610, a control circuit board 620, an abutment plate 630, a battery 640 and a housing 650.

[0034] See also Figure 4 and Figure 6 In some embodiments, the housing 650 is made of aluminum material, the sealing cover 610 is located inside the housing 650, and a sensor is sleeved inside the sealing cover 610. The sensor is commonly known as a microphone. The sealing cover 610 includes a sealing portion 611 and a protruding portion 612. The protruding portion 612 is connected to the surface of the sealing portion 611, and the protruding portion 612 protrudes a certain height relative to the surface of the sealing portion 611. A sensing channel 613 is provided on the protruding portion 612. The sensing channel 613 is connected to the air flow channel in the atomizer 11. When the user inhales at the end of the air flow channel, a negative pressure will be generated in the air flow channel. The sensor will sense the existence of the negative pressure through the sensing channel 613 and transmit the negative pressure signal to the control circuit board 620, so that the control circuit board 620 controls the battery 640 to power the atomizer 11, thereby causing the liquid in the atomizer 11 to be atomized to form smoke for the user to inhale. Generally, a small amount of liquid in the atomizer 11 will leak out of the atomizer 11 to form liquid leakage, and the leaked liquid will flow along the atomizer 11. Figure 4 The path indicated by the dotted arrow drops into the sensing channel 613 .

[0035] See also Figure 4 and Fig.12 In some embodiments, the mounting frame 300 is disposed within the housing 650, and a receiving cavity 500 is provided on the mounting frame 300 and the housing 650, so that most of the receiving cavity 500 is located on the mounting frame 300, and a small part of the receiving cavity 500 is located on the housing 650. The mounting frame 300 is also provided with a mounting cavity 310, and the mounting cavity 310 is used to accommodate the battery 640. The abutment plate 630 can be fixed on the mounting frame 300 and located in the receiving cavity 500. Through the separation effect of the abutment plate 630, the receiving cavity 500 is divided into a front cavity 510 and a rear cavity 520. The front cavity 510 is directly connected to the outside, and the rear cavity 520 is directly connected to the sensing channel 613. Of course, the front cavity 510 and the rear cavity 520 are also connected to each other.

[0036] See also Figure 6The raised portion 612 of the sealing cover 610 cooperates with the rear cavity 520, so that the raised portion 612 can make full use of the existing space of the rear cavity 520, and prevent the raised portion 612 from occupying other installation space outside the accommodating cavity 500, so as to ensure the compactness of the structure of the power supply 12. The sealing portion 611 of the sealing cover 610 can be connected to the mounting frame 300, so that the sealing cover 610 can seal the part of the front cavity 510 located on the mounting frame 300 and the entire rear cavity 520, and then the sealing cover 610 forms a sealing effect on the accommodating cavity 500, and the accommodating cavity 500 closed by the sealing cover 610 will not be connected with the mounting cavity 310 and will be isolated from each other.

[0037] See also Figure 3 and Figure 5 In some embodiments, the support frame 100 can be detachably disposed in the accommodating cavity 500, for example, the support frame 100 is connected to the inner wall surface of the accommodating cavity 500 by snap connection, magnetic connection, elastic press connection or push-push connection, as long as the support frame 100 can be detached from the connection between the outer shell 650 and the mounting frame 300 to be removed from the accommodating cavity 500.

[0038] See also Fig.10 and Fig.11 The support frame 100 includes a bottom plate 120, an end plate 130, a side plate 140 and a baffle 150. The number of the bottom plate 120 and the short plate is one, and the number of the side plate 140 and the baffle 150 is two. The short plate is 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 baffles 150 is bent and connected to one end of one of the side plates 140 away from the end plate 130, and the other baffle 150 is bent and connected to one end of the other side plate 140 away from the end plate 130. For example, the baffle 150 and the side plates 140 can be perpendicular to each other. The bottom plate 120, the end plate 130, the side plate 140 and the baffle plate 150 enclose a first cavity 111, and the two baffle plates 150 and the bottom plate 120 together enclose a second cavity 112. The cross-sectional dimension of the first cavity 111 is greater than the cross-sectional dimension of the second cavity 112, and the first cavity 111 and the second cavity 112 together form an open cavity 110. During the processing, the open cavity 110 can be regarded as formed by a portion of the outer surface of the support frame 100 being recessed to a set depth along the thickness direction of the support frame 100.

[0039] The liquid storage part 200 can be made of cotton material, so that the micropores in the liquid storage part 200 can absorb and store a large amount of liquid. The liquid storage part 200 includes a first liquid storage part 210 and a second liquid storage part 220. The second liquid storage part 220 is connected to the end surface of the first liquid storage part 210. The second liquid storage part 220 protrudes a certain height relative to the end surface, and the cross-sectional size of the first liquid storage part 210 is greater than the cross-sectional size of the second liquid storage part 220. The size of the first liquid storage part 210 is adapted to the first cavity 111, so that the first liquid storage part 210 can be completely accommodated in the first cavity 111; the size of the second liquid storage part 220 is adapted to the second cavity 112, so that a part of the second liquid storage part 220 is accommodated in the second cavity 112, and at the same time, another part of the second liquid storage part 220 is accommodated in the rear cavity 520 of the accommodating cavity 500.

[0040] When the first liquid storage part 210 is installed into the first cavity 111 along the thickness direction of the support frame 100, the two side plates 140 clamp and limit the first liquid storage part 210 along the length direction of the bottom plate 120. At the same time, the end plate 130 and the two baffles 150 clamp and limit the first liquid storage part 210 along the width direction of the bottom plate 120 to prevent the liquid storage part 200 from shifting relative to the support frame 100, thereby improving the stability and reliability of the installation of the entire liquid storage part 200 on the support frame 100.

[0041] The end plate 130 has a mounting surface 131, which defines a part of the boundary of the first cavity 111, so that the mounting surface 131 can abut against the first liquid storage part 210. A perspective hole 131a is formed in a depression on the mounting surface 131. Obviously, the perspective hole 131a is connected to the first cavity 111. The end plate 130 includes a perspective portion 132, which can be a flat plate structure. The perspective portion 132 covers the end of the perspective hole 131a away from the first cavity 111. Through the action of the perspective portion 132, the perspective hole 131a is isolated from the outside world to prevent external dust and liquid from entering the first cavity 111 through the perspective hole 131a and corroding the oil storage part. In the case that the liquid storage part 200 changes color, the user can perceive the color change of the liquid storage part 200 itself through the perspective portion 132 and the perspective hole 131a. The thickness of the perspective portion 132 can be relatively thin, so that the color change of the liquid storage part 200 is more clearly and eye-catchingly presented to the user.

[0042] See also Figure 7 , Figure 8 and Fig. 9When the support frame 100 carrying the liquid storage part 200 is installed in the accommodating cavity 500, that is, after the support frame 100 moves relative to the housing 650 and the mounting frame 300 and is inserted into the accommodating cavity 500, the support frame 100 is completely matched with the front cavity 510 of the accommodating cavity 500, the end of the second liquid storage part 220 is located in the rear cavity 520 of the accommodating cavity 500, and the end of the support frame 100 is in contact with the abutment plate 630, so that the support frame 100 cannot continue to move relative to the accommodating cavity 500. Therefore, through the limiting effect of the abutment plate 630, on the one hand, it can play a prompting role in the installation of the support frame 100 in place, and on the other hand, it will also improve the stability and reliability of the installation of the support frame 100. At the same time, the opening of the open cavity 110 is arranged toward the sealing cover 610. Since the sealing cover 610 seals the portion of the front cavity 510 located on the mounting frame 300 and the entire rear cavity 520, the sealing cover 610 will cover the opening of the open cavity 110, so that the sealing cover 610 forms a sealing effect on the open cavity 110. The control circuit board 620 is connected to the surface of the sealing cover 610 facing away from the accommodating cavity 500, so that the control circuit board 620 is located outside the accommodating cavity 500 and the open cavity 110. That is, through the isolation effect of the sealing cover 610, the control circuit board 620 is prevented from forming a direct contact relationship with the liquid storage member 200.

[0043] When the support frame 100 carrying the liquid storage member 200 is installed in the accommodating chamber 500, when the leaked liquid in the atomizer 11 enters the sensing channel 613 of the sealing cover 610, the leaked liquid in the sensing channel 613 will further drip into the rear cavity 520 of the accommodating chamber 500. Since the end of the second liquid storage part 220 of the liquid storage member 200 is located in the rear cavity 520, the second liquid storage part 220 will absorb the leaked liquid in the rear cavity 520, thereby storing the leaked liquid in the rear cavity 520 in the entire liquid storage member 200, and preventing the leaked liquid from flowing out of the entire accommodating chamber 500.

[0044] When the liquid storage member 200 does not absorb the leaked liquid, the color presented by the liquid storage member 200 is the first color, which may be white or black, etc. When the liquid storage member 200 absorbs the leaked liquid to saturation, the color presented by the liquid storage member 200 is the second color, for example, the second color is a brighter and more eye-catching red or blue, etc., and the second color is perceived by the user through the above-mentioned perspective hole 131a and the perspective portion 132. Therefore, when the color presented by the liquid storage member 200 through the perspective portion 132 is the second color, the user can make a judgment that the storage member 200 has reached saturation in storing the leaked liquid based on the second color. At this time, the connection between the support frame 100 and the outer shell 650 and the mounting frame 300 can be released, the support frame 100 can be pulled out from the accommodating cavity 500, and then the liquid storage component 200 that has been saturated with the leaked liquid storage is unloaded from the support frame 100 and discarded, and then a new liquid storage component 200 that has not absorbed any liquid is installed in the open cavity 110 of the support frame 100, and finally the support frame 100 carrying the new liquid storage component 200 is re-accommodated in the accommodating cavity 500.

[0045] If the liquid storage part 200 that is saturated with the leaked liquid cannot be replaced, or if the liquid storage part 200 cannot be replaced in time because it cannot be accurately determined that the leaked liquid is saturated, the leaked liquid that cannot be absorbed by the liquid storage part 200 will fill the entire accommodating cavity 500 until it flows into the sensing channel 613, and then the leaked liquid will block the sensing channel 613, causing the electronic atomization device 10 to be unable to start normally because it cannot sense the negative pressure in the atomizer 11. In addition, the leaked liquid can also overflow from the accommodating cavity 500 and flow into components such as the battery 640, the control circuit board 620 and the sensor, thereby corroding the above components and ultimately affecting the service life of the electronic atomization device 10.

[0046] As for the electronic atomization device 10 of the above embodiment, first, the user can judge whether the leakage liquid stored in the liquid storage part 200 is saturated according to the color presented by the perspective part 132, and then the user can take the support frame 100 out of the accommodating chamber 500, and discard the liquid storage part 200 that is saturated with leakage liquid storage, and replace the liquid storage part 200 that is saturated with leakage liquid storage with a new liquid storage part 200 and accommodate it in the accommodating chamber 500 with the support frame 100, so that the new liquid storage part 200 can continue to absorb the leakage liquid. Therefore, by perceiving the second color and installing and removing the support frame 100, the liquid storage part 200 that is saturated with leakage liquid storage can be periodically replaced with a new liquid storage part 200. It prevents the liquid storage part 200 from filling the entire accommodating chamber 500 due to the inability of the liquid storage part 200 to continue to absorb the leaked liquid, and further prevents the leaked liquid from blocking the sensing channel 613 and affecting the normal startup of the electronic atomization device 10. It can also effectively prevent the leaked liquid from overflowing from the accommodating chamber 500 and the sensing channel 613 and corroding the battery 640, the control circuit board 620, the sensor and other components, thereby improving the service life of the power supply 12 and the electronic atomization device 10. It can also reduce the risk of explosion of the battery 640 due to the erosion of the leaked liquid, and improve the safety of the electronic atomization device 10 during use. In addition, the liquid storage part 200 that is saturated with the leaked liquid storage can be periodically replaced by simply removing the support frame 100 from the accommodating chamber 500, thereby improving the convenience of cleaning the leaked liquid.

[0047] In other embodiments, the support frame 100 can be replaced by using a switch door. For example, the switch door is rotatably arranged on the housing 650 so that the switch door can open or close the accommodating chamber 500. When the liquid storage member 200 is sensed to be in the second color through the switch door, the switch door can be opened, the liquid storage member 200 that is saturated with the leaking liquid storage is taken out from the accommodating chamber 500, and then a new liquid storage member 200 is accommodated in the accommodating chamber 500, and finally the switch door is closed. Therefore, by opening and closing the switch door, a new liquid storage member 200 can also be installed in the accommodating chamber 500 to replace the liquid storage member 200 that is saturated with the leaking liquid storage.

[0048] See also Figure 5 , Figure 6 and Fig. 9The sealing cover 610 can be made of silicone material. 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 sealing and isolating effect of the sealing cover 610 can prevent the control circuit board 620 from directly contacting the liquid storage part 200, so that the leaked liquid on the liquid storage part 200 cannot corrode the control circuit board 620, thereby improving the service life of the power supply 12. At the same time, the sealing effect of the sealing cover 610 can isolate the accommodating cavity 500 and the installation cavity 310 from each other, preventing the leaked liquid stored in the liquid storage part 200 from dripping from the accommodating cavity 500 to the installation cavity 310 and corroding the battery 640, which can also improve the service life of the power supply 12.

[0049] See also Figure 5 and Fig.11 In some embodiments, the seal 400 may be an O-ring, and the support frame 100 is provided with an annular limiting groove 160, and the seal 400 cooperates with the limiting groove 160, so that a part of the seal 400 is completely contained in the limiting groove 160, and another part of the seal 400 is located outside the limiting groove 160. After the support frame 100 is installed in the accommodating cavity 500, the entire seal 400 will be pressed between the inner wall surface of the accommodating cavity 500 and the support frame 100, so that the seal 400 seals the entire accommodating cavity 500, and prevents the liquid in the liquid storage part 200 and the accommodating cavity 500 from leaking out of the housing 650.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
