Description

TECHNICAL FIELD

As a substitute for cigarettes, the electronic atomization device is deeply loved by the majority of smokers. The traditional electronic atomization device is composed of an atomization assembly and a power supply assembly. The atomization assembly has an oil storage cavity and an atomization core inside. The atomization medium is stored in the oil storage cavity. The power supply assembly supplies power to the atomization core to heat and atomize the atomization medium in the oil storage cavity to generate aerosol for users to smoke.

[0003] At present, the traditional electronic atomization device generally has an atomization cavity in the atomization assembly. The atomization core is arranged in the atomization cavity. The bottom wall of the atomization cavity is provided with an air hole for air flow to enter the atomization cavity to realize the inflow of external air flow. This structure has the following defects: on the one hand, if the user stops using the electronic atomization device, the aerosol will stay in the atomization cavity and condense into liquid condensate on the cavity wall or the inner wall of the air flow channel. When the condensate deposits too much, it may flow downward along the air hole into the power supply assembly, causing short circuit and other phenomena, resulting in that the electronic atomization device cannot be used normally. On the other hand, when the user uses the electronic atomization device to inhale, the aerosol is also easy to flow reversely through the above-mentioned air hole and then flow reversely from the air inlet, so that the condensate formed after the aerosol is cooled will be attached near the air inlet, thereby dirtying the user's hand or the shell of the electronic atomization device, causing the user a bad use experience.

It can be understood that in other embodiments, the electronic atomization device of the present application is not limited to an electronic cigarette, but can also be any electronic atomization device that can atomize atomization medium into an aerosol, which is not limited here.

[0035] Referring to Figures 1 to 4 , Figure 1 Fig. 1 shows a schematic view of the appearance of an electronic atomization device 10 in an embodiment of the present application, Figure 2 Fig. 2 shows a top view of the electronic atomization device 10, Figure 3 and Figure 4An internal structure cross-sectional view of the electronic atomization device 10 is shown. The electronic atomization device 10 provided by an embodiment of the present application includes a housing 100, a support 200, and a power supply assembly 300, wherein the support 200 is arranged in the housing 100 and forms an oil storage cavity 101 with the inner wall of the housing 100 for storing atomization medium, and the power supply assembly 300 is connected to the support 200. The power supply assembly 300 is used to supply power to the support 200, and the support 200 is used to heat the atomization medium flowing into the support 200 from the oil storage cavity 101 under the action of the electric energy provided by the power supply assembly 300, so that the atomization medium can be atomized to generate aerosol for a user to inhale.

[0036] Specifically, in one embodiment, the housing 100 includes an upper housing 110 and a lower housing 120, one end of the upper housing 110 is open, the lower housing 120 is connected to the lower housing 120 and closes the opening of the upper housing 110, the end of the upper housing 110 away from the opening is provided with a suction nozzle 111, the suction nozzle 111 is provided with a gas outlet 112 communicating with the inner cavity of the housing 100, and the end of the lower housing 120 away from the upper housing 110 is provided with a gas inlet 121 communicating with the inner cavity of the housing 100, so that the gas inlet 121 and the gas outlet 112 are located at opposite ends of the housing 100 and communicate with each other; a ventilation pipe 113 extending from the inner wall of the housing 100 towards the inner cavity of the housing 100 is connected to the inner side of the suction nozzle 111, and the inside of the ventilation pipe 113 is formed with a gas flow channel 113a penetrating through both ends thereof and communicating with the gas inlet 121 and the gas outlet 112. The support 200 is arranged in the upper housing 110 and connected to the end of the ventilation pipe 113 away from the gas outlet 112, so that one side of the support 200 forms the oil storage cavity 101 with the inner wall of the upper housing 110; the side of the support 200 away from the oil storage cavity 101 forms a mounting position 122 with the inner wall of the lower housing 120, and the power supply assembly 300 is arranged in the mounting position 122 and electrically connected to the support 200.

[0037] It can be understood that the upper housing 110 and the lower housing 120 can be detachable from each other, or can be integrally connected, and it can also be understood that an oil storage assembly can be additionally arranged in the housing 100, and the oil storage cavity 101 is arranged in the oil storage assembly, which is not particularly limited above. When the upper housing 110 and the lower housing 120 are detachable structures, the upper housing 110 and the support 200 form a cartridge, and the lower housing 120 and the power supply assembly 300 form a rod detachably connected to the cartridge.

[0038] More specifically, in terms of the specific structure of the support 200 and the power supply assembly 300, the power supply assembly 300 includes a battery, a PCB board connected to the battery, and a gas flow sensor connected to the PCB board, and the like, which can be specifically referred to the prior art, and will not be described here. The structure of the support 200 will be described in detail below.

[0039] Referring to Figure 3 and Figure 4In one embodiment, the support 200 is provided with an atomization cavity 201 communicating with the airflow passage 113a, the top wall of the atomization cavity 201 is provided with a mounting groove 202 communicating with the oil storage cavity 101, the mounting groove 202 is provided with an atomization core 400 electrically connected to the power supply assembly 300, and the bottom wall of the atomization cavity 201 is provided with an air vent hole 203 penetrating through the atomization cavity 201 from the inside to the outside, the air vent hole 203 communicating with the air inlet 121.

[0040] When the user performs a suction action to make the atomization core 400 electrically conductive with the power supply assembly 300, the atomization core 400 works to heat the atomization medium flowing from the oil storage cavity 101 to the atomization core 400, so that the atomization medium generates aerosol in the atomization cavity 201, the external air enters the mounting position 122 from the air inlet 121, and also enters the atomization cavity 201 through the air vent hole 203, and then directly enters the airflow passage 113a after mixing with the aerosol, and then is inhaled by the user from the air outlet 112.

[0041] However, as described in the background: on the one hand, if the user stops using the electronic atomization device 10, the aerosol will remain in the atomization cavity 201 and condense into liquid condensate on the cavity wall of the atomization cavity 201 or the inner wall of the airflow passage 113a, when the condensate deposits too much, it is likely to flow down along the air hole into the power supply assembly 300, thereby causing a short circuit and other phenomena, resulting in the electronic atomization device 10 cannot be used normally. On the other hand, when the user inhales while using the electronic atomization device 10, the aerosol is also easy to flow reversely through the above-mentioned air hole, and then flow reversely from the air inlet 121, so that the condensate formed after the aerosol is cooled will be attached near the air inlet 121, thereby polluting the shell of the electronic atomization device 10, causing the user to have a bad use experience.

[0042] Therefore, in order to solve the above problems, as Figure 3 and Figure 4The applicant of the present application conceives to set a isolation cover 500 in the atomization cavity 201, the isolation cover 500 divides the atomization cavity 201 into an atomization area 201a and an isolation area 201b, the air hole 203 is covered in the isolation area 201b, and the isolation cover 500 is provided with a gas passing hole 501 communicating the atomization area 201a and the isolation area 201b, so that the air hole 203 communicates with the air outlet 112. And the air hole 203, the gas passing hole 501 and the airflow channel 113a are not located on the same straight line along the vertical direction (X direction shown in the figure), the condensate formed in the airflow channel 113a or the atomization area 201a can only flow to the isolation cover 500 and cannot enter the isolation area 201b; and due to the blocking of the isolation cover 500, the aerosol cannot directly flow out of the air inlet 121 of the shell 100 along the vertical direction, thereby solving the problem that the condensate deposited in the atomization cavity 201 or the airflow channel 113a and the aerosol in the atomization cavity 201 or the airflow channel 113a easily flow out in the opposite direction along the air hole of the support 200, causing liquid leakage.

[0043] Further, the support 200 is also provided with an oil absorption cavity 204, and the isolation cover 500 and the support 200 form a gap communicating the atomization area 201a and the oil absorption cavity 204, which is configured to pass the condensate formed in the atomization area 201a or the airflow channel 113a, so that the condensate can flow into the oil absorption cavity 204.

[0044] In this way, by setting the isolation cover 500, the flow direction of the condensate can be changed, so that the condensate flows into the oil absorption cavity 204, thereby effectively preventing the condensate from being deposited in the atomization cavity 201, and further effectively preventing the condensate from entering the inside of the tobacco rod, increasing the service life of the tobacco rod, and reducing the risk of self-activation of the PCB board in the power supply assembly 300 due to short circuit.

[0045] Further, the oil absorption cavity 204 is provided with a first oil absorption cotton 600, which is used to absorb the condensate flowing from the atomization area 201a to the oil absorption cavity 204, preventing the condensate from flowing randomly in the oil absorption cavity 204. On this basis, the atomization assembly is also provided with a second oil absorption cotton 700, part of which is located in the atomization cavity 201 and the other part extends into the oil absorption cavity 204, and the isolation cover 500 is arranged on the second oil absorption cotton 700, and the first oil absorption cotton 600 is placed on the second oil absorption cotton 700, thereby further fully absorbing the condensate and further reducing the risk of the condensate flowing into the inside of the tobacco rod.

[0046] In order to better drain the condensate dripping on the isolation cover 500, in an improved embodiment, as shown in Figure 5As shown, the isolation cover 500 is provided with a flow guide surface 502 inclined towards the oil absorption cavity 204. Specifically, the plane on which the flow guide surface 502 is located forms an angle with the horizontal direction (Y direction shown in the figure) perpendicular to the vertical direction, so that the height of the isolation cover 500 in the vertical direction perpendicular to the horizontal direction gradually decreases from the direction in which the central axis of the airflow channel 113a points to the oil absorption cavity 204.

[0047] In this way, when the condensed liquid drops on the isolation cover 500, the condensed liquid can flow along the inclined flow guide surface 502 under the action of gravity, and then flow into the oil absorption cavity 204 through the gap formed by the isolation cover 500 and the support 200.

[0048] Further, in order to avoid the condensed liquid from gathering in the atomization cavity 201 and to ensure that the condensed liquid can be completely guided to the oil absorption cavity 204, the oil absorption cavity 204 and the flow guide surface 502 are provided with two respectively, and the two oil absorption cavities 204 and the two flow guide surfaces 502 are symmetrically arranged with respect to the central axis of the airflow channel 113a.

[0049] As can be seen, the condensed liquid that drops on the isolation cover 500 can flow to both sides towards the oil absorption cavity 204 under the action of gravity, so that the condensed liquid on the isolation cover 500 can quickly flow into the oil absorption cavity 204, thereby keeping the isolation cover 500 clean and reducing the broken sound caused by the accumulation of condensed liquid during suction, and improving the user's suction experience.

[0050] Further, as shown, Figure 6 each flow guide surface 502 is further provided with a plurality of flow guide strips 503, each of which is arranged to extend in the direction in which the central axis of the airflow points to the oil absorption cavity 204, so that the plurality of flow guide strips 503 form a plurality of flow guide grooves 504; preferably, the plurality of flow guide strips 503 are arranged in parallel with each other, so that the plurality of flow guide grooves 504 are also arranged in parallel with each other. In this way, the condensed liquid can flow into the oil absorption cavity 204 along the plurality of flow guide grooves 504 arranged in parallel with each other, so that the condensed liquid can only flow into the oil absorption cavity 204, avoiding the condensed liquid from flowing to other positions in the atomization cavity 201.

[0051] As an improvement of the above-mentioned embodiments, please continue to refer to Figure 5 and Figure 6, the bottom wall of the atomization cavity 201 is provided with a first air guide column 205, and the air passage 203 penetrates through the first air guide column 205. Optionally, the top wall of the isolation cover 500 is provided with a second air guide column 505, and the air passage 501 penetrates through the second air guide column 505. The above design can make the opening of the air passage 203 higher than the bottom wall of the atomization cavity 201, and make the opening of the air passage 501 higher than the top wall of the isolation cover 500. Therefore, the condensed liquid that drips onto the top wall of the isolation cover 500 can be prevented from flowing into the isolation area 201b along the air passage 501. Even if there is condensed liquid in the isolation area 201b, the condensed liquid will not flow into the cartridge along the air passage 203 (i.e., into the mounting position 122).

[0052] More preferably, in one embodiment, as Figure 5 and Figure 6 The cavity wall (for example, the top wall) of the atomization cavity 201 is provided with two mounting grooves 202, the groove wall of each mounting groove 202 is provided with an oil guide hole 206 that communicates with the oil storage cavity 101, the oil storage cavity 101 communicates with the mounting groove 202 through the oil guide hole 206, and one atomization core 400 is respectively arranged in each mounting groove 202.

[0053] In this way, compared with the structure of the conventional atomization assembly that has only one atomization core 400, the atomization assembly of the above embodiment is provided with two atomization cores 400, so that the heat generation can be increased, and therefore more atomization medium can be heated in unit time. Of course, the number of atomization cores 400 is not limited, and can be more, which is not limited herein.

[0054] In addition, the air passage 501 provided on the isolation cover 500 is also provided with two, and the two air passages 501 are symmetrically arranged with respect to the center axis of the airflow channel 113a. The isolation cover 500 is provided with an isolation plate 800 at a position close to the airflow channel 113a and opposite to the center axis of the airflow channel 113a, and the isolation plate 800 is used to divide the atomization area 201a into two sub-atomization areas 201a. By such arrangement, the airflow entering the atomization area 201a from the isolation area 201b through the two air passages 501 is isolated by the isolation plate 800 and does not interfere with each other in the atomization area 201a. Therefore, the condensation sound caused by suction can be reduced during suction, and the user's experience can be improved to some extent.

[0055] It should be noted that the number of air passages 501 provided on the isolation cover 500 is not limited, and can be one or more.

[0056] Please refer to Figure 6In the electric connection mode between the atomization core 400 and the power supply assembly 300, in an embodiment, the support 200 is provided with the pogo pins 900, and the power supply assembly 300 is electrically connected to the atomization core 400 through the pogo pins 900. Specifically, in the embodiment shown in the figure, the pogo pins 900 are four, and the four pogo pins 900 are divided into two groups of pogo pins 900, and each atomization core 400 is electrically connected to the power supply assembly 300 through a group of pogo pins 900; each group of pogo pins 900 includes two pogo pins 900, and the two pogo pins 900 represent the positive and negative electrodes respectively, one end of each pogo pin 900 extends into the atomization cavity 201 and abuts against the heating body of the atomization core 400, and the other end is electrically connected to the power supply assembly 300, thereby realizing the electric connection between the two atomization cores 400 and the power supply assembly 300. It is not difficult to understand that the number of the group of pogo pins 900 is the same as the number of the atomization core 400, which can be determined according to the number of the atomization core 400, and it can be understood that the atomization core 400 can also be electrically connected to the power supply assembly 300 through a wire, which is not limited here.

[0057] Therefore, it can be seen that the electronic atomization device 10 provided by the present application can make the condensate generated in the atomization cavity 201 flow quickly to the oil absorption cavity 204 by arranging the isolation cover 500 in the atomization cavity 201, which not only can prevent the condensate from flowing into the power supply assembly 300 or flowing out from the air inlet 121, but also can avoid the atomization medium from flowing out from the bottom air inlet 121 in an extreme case, thereby reducing the safety hazard; and also can prevent the aerosol from flowing out reversely from the air inlet 121, reducing the suction of the condensate, and greatly improving the user experience.

[0058] The technical features of the above-described embodiments can be combined arbitrarily, and to make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.

[0059] The above-described embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
