Description

Technical Field

[0001] The present application relates to the field of atomization technology, and in particular to an electronic atomization device. Background Art

[0002] An electronic atomization device generally includes an atomizer portion and a power supply main body portion. The atomizer portion mainly stores liquid through a liquid storage chamber, and under the power supply control of the power supply main body portion, the stored liquid is converted into an aerosol through the atomization component, and then sprayed outward through the air flow channel for the user to inhale. As is well known, electronic atomization devices will produce a lot of condensation during use, and it will flow to the power supply main body portion along the inlet of the air flow channel. In order to prevent these condensation liquids from contaminating the power supply components in the power supply main body portion, the existing electronic atomization components will be provided with absorbent cotton at the inlet of the power supply main body portion facing the air flow channel to absorb these condensation liquids. However, in actual use, it was found that due to the limited space here, and at the same time, in order to prevent the setting of the absorbent cotton from affecting the air intake of the inlet of the air flow channel, only a very small piece of absorbent cotton can be provided here, resulting in a limited absorption area and poor absorption effect. There is still a risk of condensation liquid contaminating the power supply components, affecting the service life of the electronic atomization device. Utility Model Content

The preset direction is perpendicular to the extension direction of the air flow channel.

[0014] The liquid storage cavity is provided with a liquid outlet with a movable seal on a side surface facing the liquid storage cavity mounting groove, so that after the movable cover is removed from the liquid inlet, when the liquid storage cavity is plugged and installed in the liquid storage cavity mounting groove along the preset direction, the liquid inlet channel is inserted into the liquid outlet, and the liquid storage cavity is in liquid communication with the liquid storage cotton;

At the same time, since the absorbent cotton is arranged on the peripheral side of the second chamber which has sufficient space and does not affect the air intake of the inlet of the air flow channel, rather than being directly arranged on the bottom wall of the first chamber as is currently the case, it can be provided with absorbent cotton of sufficient size according to the actual liquid absorption effect requirements to ensure its liquid absorption area and liquid absorption effect, so as to reduce the risk of condensate contaminating the power supply component and improve the service life of the electronic atomization device.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features.

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.

[0032] In one embodiment, Figures 1 to 3As shown, the embodiment of the present application also provides an electronic atomization device 1, which may specifically include an atomizer part 100 and a power supply main body 200. Among them, the atomizer part 100 may specifically be equipped with a liquid storage chamber 120, an air flow channel 1121 and an atomization component 130, and is mainly used to heat the liquid in the liquid storage chamber 120 through the atomization component 130 in the air flow channel 1121 to form an aerosol. The power supply main body 200 may be specifically connected to the end of the atomizer part 100 having the inlet of the air flow channel 1121, and the power supply main body 200 is equipped with a first chamber 211, a second chamber 212 and a placement groove body 213. The first chamber 211 and the second chamber 212 are adjacent to each other in the inlet direction of the air flow channel 1121. The placement groove body 213 is located on the peripheral side of the second chamber 212. The top wall of the first chamber 211 is provided with the inlet of the air flow channel 1121. The first chamber 211 The bottom wall is provided with a notch and an air hole 214, the notch is provided corresponding to the placement groove body 213 (that is, the opening of the placement groove body 213), the air hole 214 is connected to the second chamber 212, the air hole 214 and the inlet of the air flow channel 1121 are staggered in the extension direction of the air flow channel 1121, and a liquid-absorbing cotton is provided in the placement groove body 213, and the second chamber 212 is respectively provided with a power supply component 230 electrically connected to the atomization component 130 and an air inlet channel connected to the air hole 214.

[0033] It can be understood that the above-mentioned atomizer part 100 is the main component of the electronic atomization device 1 of the embodiment of the present application, which is mainly used to store liquid through the liquid storage chamber 120, and under the power supply control of the power supply main body 200, the stored specific liquid (specifically, it can be an atomized liquid such as tobacco oil) is converted into an aerosol through the atomization component 130, and then sprayed outward through the air flow channel 1121 for the user to inhale. The top wall of the first chamber 211 mentioned above specifically refers to the inner wall on one side of the first chamber 211 close to the atomizer part 100. The bottom wall of the first chamber 211 mentioned above specifically refers to the inner wall on one side of the first chamber 211 close to the second chamber 212. The above-mentioned absorbent cotton is generally made of organic cotton or polyester fiber. The good liquid absorption capacity of organic cotton or polyester fiber itself can absorb the condensate flowing out of the inlet of the air flow channel 1121 in time. The power supply assembly 230 mentioned above may specifically include a battery and a charging interface, wherein the battery is installed in the second chamber 212 and the charging interface is exposed on the surface of the power supply body 200 to facilitate corresponding charging operations.

[0034] In this way, the electronic atomization device 1 provided in the embodiment of the present application has a top wall of the first chamber 211 of its power supply main body 200 provided with an inlet of the air flow channel 1121, and the bottom wall of the first chamber 211 is respectively provided with slots corresponding to the placement groove body 213 and air holes 214 connected to the second chamber 212, and the air holes 214 and the inlet of the air flow channel 1121 are staggered in the extension direction of the air flow channel 1121, so that after the condensate flows out from the inlet of the air flow channel 1121, it will not directly drip through the air holes 214, but will flow through the bottom wall of the first chamber 211 to the slot of the placement groove body 213, so as to ensure that the absorbent cotton in the placement groove body 213 can absorb the condensate in time. At the same time, since the absorbent cotton is arranged on the surrounding side of the second chamber 212 where there is sufficient space and will not affect the air intake of the inlet of the air flow channel 1121, rather than being directly arranged on the bottom wall of the first chamber 211 as is currently the case, it is possible to set absorbent cotton of sufficient size according to the actual absorption effect requirements to ensure its absorption area and absorption effect, thereby reducing the risk of condensation liquid contaminating the power supply component 230 and improving the service life of the electronic atomization device 1.

[0035] In some examples, such as Figure 2 and Figure 3 As shown, the power supply body 200 is internally provided with two receiving grooves 213. These grooves 213 are located around the second chamber 212 and are arranged opposite each other to surround the second chamber 212. Each receiving groove 213 houses a liquid-absorbing sponge. This structure further utilizes the space around the second chamber 212, creating a dual-absorbing sponge structure within the power supply body 200. This further increases the absorbent sponge's surface area and enhances its absorbent efficiency.

[0036] In some examples, such as Figure 2 and Figure 3 As shown, the air hole 214 is located on one side of the first chamber 211 and is provided with an annular boss along its periphery. This structure ensures that condensate flowing out of the inlet of the airflow channel 1121 and dripping onto the bottom wall of the first chamber 211 will not drip into the second chamber 212 through the air hole 214, thereby further reducing the risk of condensate contaminating the power supply assembly 230 and extending the service life of the electronic atomization device 1. Furthermore, the length of the absorbent cotton in the direction of the airflow channel 1121 is greater than the depth of the groove 213 in the direction of the airflow channel 1121. In this way, through the above-mentioned structural setting, when the absorbent cotton is set in the corresponding placement groove body 213, it will enter the first chamber 211 from a portion of the notch protruding from the placement groove body 213. This not only further increases the liquid absorption area of ​​the absorbent cotton, but also allows the condensed liquid flowing into the notch of the placement groove body 213 to be promptly absorbed by the corresponding absorbent cotton, thereby further improving the liquid absorption effect of the absorbent cotton.

[0037] In some examples, such as Figure 2 and Figure 3 As shown, the bottom wall of the first chamber 211 is also provided with a liquid guiding slope (not shown) inclined toward the notch of the placement tank body 213, which is used to guide the condensate flowing out of the inlet of the air flow channel 1121 to the notch of the placement tank body 213 when the condensate flowing out of the inlet of the air flow channel 1121 drips onto the bottom wall of the first chamber 211. In this way, through the above-mentioned structural arrangement, it can be further ensured that the condensate will only flow into the notch of the placement tank body 213, so as to further improve the liquid absorption effect of the absorbent cotton and reduce the risk of the condensate contaminating the power supply component 230, so as to improve the service life of the electronic atomization device 1. Furthermore, the surface of the power supply component 230 is covered with a liquid absorbent material layer. In this way, through the above-mentioned structural arrangement, when the condensate enters the second chamber 212 through the air hole 214, the liquid absorbent material layer can absorb the condensate in time to improve the service life of the electronic atomization device 1.

[0038] In some examples, such as Figures 1 to 4As shown, the atomizer part 100 includes a shell assembly 110, a liquid storage chamber 120 and an atomization assembly 130, wherein the shell assembly 110 has built-in liquid storage cotton 1122 and an air flow channel 1121, the liquid storage cotton 1122 is arranged around the air flow channel 1121, and the peripheral surface of the shell assembly 110 is recessed with a liquid storage chamber mounting groove 1123, and the groove wall of the liquid storage chamber mounting groove 1123 is convexly provided with a liquid inlet channel 1124 extending along a preset direction, the inner side of the liquid inlet channel 1124 abuts the liquid storage cotton 1122, and the outer side of the liquid inlet channel 1124 is provided with a liquid inlet with a movable cover body 1125, and the preset direction is perpendicular to the extension direction of the air flow channel 1121. A liquid outlet with a movable seal 121 is provided on the side of the liquid storage chamber 120 facing the liquid storage chamber mounting slot 1123. After removing the movable cover 1125 from the liquid inlet, when the liquid storage chamber 120 is inserted and installed in the liquid storage chamber mounting slot 1123 along a predetermined direction, the liquid inlet channel 1124 is inserted into the liquid outlet, thereby placing the liquid storage chamber 120 in liquid communication with the liquid storage sponge 1122. An atomizer assembly 130 is mounted at one end of the airflow channel 1121, away from the outlet of the airflow channel 1121, and is in liquid communication with the liquid storage sponge 1122, for heating and atomizing the liquid within the liquid storage sponge 1122 to form an aerosol. In this way, through the above-mentioned structural setting, the liquid storage chamber 120 can be separated from the shell assembly 110 for independent transportation and storage. During transportation, the liquid outlet of the liquid storage chamber 120 is sealed by the movable seal 121 to ensure that the liquid storage chamber 120 does not leak during transportation, and the liquid inlet of the liquid inlet channel 1124 is sealed by the movable cover 1125 to ensure that the liquid storage cotton 1122 is not exposed during transportation, causing the liquid storage cotton 1122 to be contaminated. At the same time, when the user needs to use the electronic atomization device 1, he only needs to remove the movable cover 1125 at the liquid inlet, and plug the liquid storage chamber 120 into the liquid storage chamber mounting groove 1123 along the preset direction, and insert the liquid inlet channel 1124 into the liquid outlet, so that the liquid connection between the liquid storage chamber 120 and the liquid storage cotton 1122 can be quickly realized, ensuring that the user can quickly and normally inhale the electronic atomization device 1 to enhance the user experience.

[0039] It is understandable that the liquid storage cotton 1122 in this example 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 120 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 and reduce odors. The liquid storage cotton 1122 in this example is arranged around the air flow channel 1121, which specifically means that the liquid storage cotton 1122 is arranged on the side of the air flow channel 1121. The preset direction in this example is specifically perpendicular to the extension direction of the air flow channel 1121, so that the liquid storage cavity 120 can be installed in the corresponding liquid storage cavity mounting groove 1123 by side plugging. In this example, the liquid storage chamber 120 is in liquid communication with the liquid storage cotton 1122, specifically referring to that when the liquid inlet channel 1124 is inserted into the liquid outlet so that the liquid inlet of the liquid inlet channel 1124 is in communication with the liquid outlet of the liquid storage chamber 120, the liquid in the liquid storage chamber 120 can flow into the liquid storage cotton 1122 through the liquid inlet channel 1124. The atomizer assembly 130 in this example can be specifically arranged at one end of the air flow channel 1121 away from the outlet of the air flow channel 1121, and the liquid communication with the liquid storage cotton 1122 specifically refers to that the end of the air flow channel 1121 away from the outlet of the air flow channel 1121 is provided with a liquid guide port, and the liquid storage cotton 1122 on the side of the air flow channel 1121 can abut against the atomizer assembly 130 through the liquid guide port, so that when there is liquid in the liquid storage cotton 1122, the liquid can flow from the liquid storage cotton 1122 to the atomizer assembly 130 through the liquid guide port.

[0040] In some examples, such as Figure 1 、 Figure 2 and Figure 3 As shown, the atomizer part 100 includes two liquid storage chambers 120, and the groove wall of the liquid storage chamber mounting groove 1123 is convexly provided with two liquid inlet channels 1124, and the two liquid storage chambers 120 are respectively inserted into the liquid storage chamber mounting groove 1123, and each liquid inlet channel 1124 is correspondingly inserted into the liquid outlet of a liquid storage chamber 120. In this way, through the above-mentioned structural setting, the atomizer part 100 can form a structural setting of two liquid storage chambers 120, and the two liquid storage chambers 120 can be separated from the shell assembly 110 for independent transportation and storage. In this way, the use mode of the atomizer part 100 can be enriched to meet the needs of users in more usage scenarios. Furthermore, the opening direction of the liquid inlet of one liquid inlet channel 1124 is opposite to the opening direction of the liquid inlet of the other liquid inlet channel 1124. Thus, through the above-mentioned structural arrangement, the dual liquid storage chambers 120 of the atomizer portion 100 can be arranged bilaterally symmetrically, thereby reducing the difficulty and cost of mold making of the liquid storage chambers 120 .

[0041] It can be understood that when the opening direction of the liquid inlet of one liquid inlet channel 1124 in this example is opposite to the opening direction of the liquid inlet of another liquid inlet channel 1124, the plug-in installation directions of the two liquid storage chambers 120 in the liquid storage chamber mounting groove 1123 should be opposite.

[0042] In some examples, such as Figure 1 and Figure 2 As shown, the movable seal 121 is a sealing film provided to cover the liquid outlet. The structural arrangement of the sealing film effectively seals the liquid outlet of the liquid storage chamber 120 during transportation and storage of the liquid storage chamber 120, preventing leakage from the liquid storage chamber 120. During use, the liquid inlet channel 1124, after breaking the sealing film through penetration, is inserted into the liquid outlet, thereby establishing communication between the liquid inlet of the liquid inlet channel 1124 and the liquid outlet of the liquid storage chamber 120.

[0043] In some examples, such as Figure 1 and Figure 2 As shown, the movable seal 121 is a sealing rubber gasket provided to cover the liquid outlet, and is provided toward the inside of the liquid outlet. The structural arrangement of the sealing rubber gasket effectively seals the liquid outlet of the liquid storage chamber 120 during transportation and storage of the liquid storage chamber 120, ensuring that no leakage occurs from the liquid storage chamber 120. The liquid inlet channel 1124 pushes the sealing rubber gasket into the liquid storage chamber 120 through the penetration force, and then inserts it into the liquid outlet, thereby completing the communication between the liquid inlet of the liquid inlet channel 1124 and the liquid outlet of the liquid storage chamber 120.

[0044] In some examples, such as Figure 1 and Figure 2 As shown, when the liquid storage chamber 120 is inserted and installed in the liquid storage chamber mounting groove 1123 along a preset direction, the outer wall of the liquid storage chamber 120 is also fastened to the groove wall of the liquid storage chamber mounting groove 1123 via a snap-fit ​​structure. In this way, the above-mentioned structural arrangement can further improve the stability of the connection between the liquid storage chamber 120 and the liquid storage chamber mounting groove 1123, and when the liquid in the liquid storage chamber 120 is used up and needs to be replaced, it is convenient to quickly remove and replace it.

[0045] In some examples, such as Figures 1 to 3As shown, the shell assembly 110 includes a base 113, a nozzle shell 111 with an air flow outlet 1111, and a first shell 112 with an air flow channel 1121 and a liquid storage cotton 1122 built in. The peripheral surface of the first shell 112 is recessed with a liquid storage cavity mounting groove 1123, the nozzle shell 111 is arranged at the first end of the first shell 112, and the air flow outlet 1111 is connected to the outlet of the air flow channel 1121, and the base 113 is arranged at the second end of the first shell 112. In this way, through the above-mentioned structural setting, a reasonable layout of the air flow channel 1121 and the liquid storage chamber 120 on the shell assembly 110 can be achieved. At the same time, since the liquid storage chamber mounting groove 1123 is recessed in the peripheral surface of the first shell 112 with the air flow channel 1121 and the liquid storage cotton 1122 built in, the liquid storage chamber mounting groove 1123 is specifically located on the peripheral side of the air flow channel 1121 and the liquid storage cotton 1122, so that when the liquid storage chamber 120 is installed in the corresponding liquid storage chamber mounting groove 1123, the liquid storage chamber 120 is also located on the peripheral side of the air flow channel 1121 and the liquid storage cotton 1122, so that the liquid storage chamber 120, the liquid storage cotton 1122 and the atomization assembly 130 in the air flow channel 1121 are liquid-connected in sequence.

[0046] In some examples, such as Figures 1 to 3 As shown, the circumferential side wall of the air flow channel 1121 at one end away from the outlet of the air flow channel 1121 is provided with at least one liquid guide port (not shown), and the atomizing assembly 130 blocks all liquid guide ports so that the atomizing assembly 130 is in liquid communication with the liquid storage cotton 1122. In this way, through the above-mentioned structural arrangement, it can be ensured that the atomizing assembly 130 is better in liquid communication with the liquid storage cotton 1122. Furthermore, two liquid guide ports are provided on the circumferential side wall of the air flow channel 1121 at one end away from the outlet of the air flow channel 1121, and the two liquid guide ports are arranged radially opposite to each other along the air flow channel 1121. In this way, through the above-mentioned structural arrangement, it can be ensured that the liquid in the liquid storage cotton 1122 penetrates more evenly into the entire atomizing assembly 130 to enhance the atomization effect of the atomizing assembly 130. Furthermore, the atomizing assembly 130 includes a liquid guide cotton and a heating element, the liquid guide cotton blocks all liquid guide ports, and the heating element is arranged on the liquid guide cotton. Thus, through the above-mentioned structural setting, the liquid in the liquid-conducting cotton can be converted into aerosol and sprayed out by the heating element through the heating work of the liquid-conducting cotton for the user to inhale.

[0047] It is understandable that the liquid-conducting cotton in this example can be made of the same material as the liquid-storing cotton 1122 to ensure that it can effectively absorb the liquid in the liquid-storing cotton 1122 and ensure the atomization effect. The number of liquid-conducting ports in this example can be arbitrarily increased or decreased according to actual needs, including but not limited to the two mentioned above. The shape of the liquid-conducting port in this example can be rectangular, circular or other shapes. The heating element in this example can be a heating sheet or a heating wire.

[0048] In some examples, such as Figures 1 to 4 As shown, the power supply body 200 includes a second housing 210 with a built-in slot 213, a bottom cover 220, and a power supply assembly 230. One end of the second housing 210 is connected to one end of the first housing 112, thereby enclosing a first chamber 211 within the first end of the second housing 210. The other end of the second housing 210 is mounted with the bottom cover 220, thereby enclosing a second chamber 212 within the second end of the second housing 210. The bottom cover 220 is also provided with an air inlet for the air inlet channel. Thus, through the above-mentioned structural arrangement, the first chamber 211 and the second chamber 212 in the above-mentioned example can be better combined and formed, and the placement of the slot 213 and the air inlet channel can be rationally arranged within the housing assembly 110.

[0049] In some examples, such as Figure 1 and Figure 5 As shown, the electronic atomization device 1 also includes a sealing rubber cap 310, which is covered on the airflow outlet 1111 to seal the airflow outlet 1111. In this way, through the above-mentioned structural arrangement, the airflow outlet 1111 can be tightly sealed by the sealing rubber cap 310 to ensure the sealing performance at the airflow outlet 1111, so as to avoid leakage here during storage after the product is used. Furthermore, the electronic atomization device 1 also includes an annular rubber ring 320, which is connected to the sealing rubber cap 310 and is arranged around the liquid storage chamber 120, so as to further tighten the connection between the liquid storage chamber 120 and the liquid storage chamber mounting groove 1123 when the liquid storage chamber 120 is plugged and installed in the liquid storage chamber mounting groove 1123 along a preset direction. In this way, the annular rubber ring 320 can be arranged around the liquid storage chamber 120 to tightly fix the liquid storage chamber 120 in the liquid storage chamber mounting groove 1123, further ensuring the secure connection between the liquid storage chamber 120 and the liquid storage chamber mounting groove 1123. At the same time, because the sealing rubber cap 310 is connected to the annular rubber ring 320, the sealing rubber cap 310 remains on the electronic atomization device 1 after being removed from the air flow outlet 1111, thereby providing a certain degree of protection against loss of the sealing rubber cap 310.

[0050] It is understood that the sealing rubber cap 310 in this example can be specifically configured as a cap-shaped structure, which can completely wrap around the end of the nozzle housing 111 having the airflow outlet 1111 to effectively seal the airflow outlet 1111. Furthermore, the inner surface of the sealing rubber cap 310 facing the airflow outlet 1111 is provided with a protrusion that is interference-fitted with the inner wall of the airflow outlet 1111 to further ensure its sealing performance against the airflow outlet 1111. The inner diameter of the annular rubber ring 320 in this example should be slightly smaller than the outer diameter of the housing assembly 110 to ensure that it can be tightly fitted around the circumference of the housing assembly 110 to further ensure the secure connection between the liquid storage chamber 120 and the liquid storage chamber mounting groove 1123.

[0051] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application description and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
