[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1 , Figure 1 A schematic structural diagram of an electronic device 1000 in the first embodiment of the present application is shown.

[0042] The electronic device 1000 includes an atomizer assembly 200 and a housing 100, wherein the atomizer assembly 200 is fixed in the housing 100. The atomizer assembly 200 is used to atomize liquid, wherein the liquid includes but is not limited to smoke liquid, liquid medicine, fragrance, etc., and the electronic device 1000 can be an electronic cigarette, a liquid medicine atomization device, a fragrance atomizer, etc. The embodiment of the present application is described by taking the liquid as smoke liquid and the electronic device 1000 as an electronic cigarette as an example.

[0043] The atomizer assembly 200 includes an atomizing core 10 and a light source 20. The atomizing core 10 includes a porous carrier 11, a first photoreversible affinity layer 12 and a heating element 13. The porous carrier 11 has a liquid guiding surface 101, an atomizing surface 102 and a side surface 103 connected between the liquid guiding surface 101 and the atomizing surface 102. The liquid guiding surface 101 and the atomizing surface 102 are arranged opposite to each other, and the liquid guiding surface 101, the atomizing surface 102 and the side surface 103 are enclosed together to form the outer surface of the porous carrier 11. The porous carrier 11 is provided with a liquid guiding channel (not shown), which runs through the liquid guiding channel and the atomizing surface 102, and the smoke liquid flows from the liquid guiding surface 101 to the atomizing surface 102 through the liquid guiding channel. In this embodiment, the porous carrier 11 is a porous ceramic, and the liquid guiding channel is a pore in the porous ceramic.

[0044] The first photoreversible affinity layer 12 covers the atomization surface 102. The smoke liquid flows through the liquid guide channel to the atomization surface 102 and contacts the first photoreversible affinity layer 12. In this embodiment, the thickness of the first photoreversible affinity layer 12 is 400nm-2μm.

[0045] The heating element 13 is installed on the atomizing surface 102, and is used to atomize the smoke liquid flowing onto the atomizing surface 102. The heating element 13 can be arranged on the area of ​​the atomizing surface 102 covered with the first photoreversible affinity layer 12, and can also be arranged on the area of ​​the atomizing surface 102 not covered with the first photoreversible affinity layer 12. In this embodiment, the first photoreversible affinity layer 12 is arranged on the atomizing surface 102, and the heating element 13 is arranged on the first photoreversible affinity layer 12. The light source 20 is located on the side of the porous carrier 11 having the atomizing surface 102, and is used to illuminate the first photoreversible affinity layer 12. In this embodiment, the light source 20 is an ultraviolet lamp. Under illumination conditions, the contact angle of the smoke liquid on the first photoreversible affinity layer 12 changes. Specifically, the light source 20 has an on state and an off state. In the off state, the contact angle of the smoke liquid on the first photoreversible affinity layer 12 is θ1. In the on state, the contact angle of the smoke liquid on the first photoreversible affinity layer 12 is θ2, which is less than the contact angle θ1 and less than 90°; that is, under light conditions, the contact angle θ2 of the smoke liquid on the first photoreversible affinity layer 12 becomes smaller, and the first photoreversible affinity layer 12 is lipophilic to the smoke liquid. In this embodiment, the contact angle θ1 of the smoke liquid on the first photoreversible affinity layer 12 is greater than or equal to 60°, and the contact angle θ2 is less than 60°. When the contact angle of the smoke liquid on the first photoreversible affinity layer 12 is greater than or equal to 60°, it is difficult for small drops of smoke liquid to gather to form a large liquid of smoke liquid, which can prevent leakage and provide a good user experience.

[0046] In the atomizer assembly 200 of the electronic device 1000 provided in this embodiment, the smoke liquid flows from the liquid guide surface 101 through the liquid guide channel to the atomization surface 102, contacts the first photoreversible affinity layer 12 covering the atomization surface 102, and is heated and atomized by the heating element installed on the atomization surface 102. When the light source 20 is in the off state, that is, when the first photoreversible affinity layer 12 is in the dark room state, the contact angle of the smoke liquid on the first photoreversible affinity layer 12 is large, and small drops of smoke liquid are difficult to gather to form large drops of smoke liquid, which can prevent the leakage of smoke liquid, and at the same time, it can avoid the problem of small drops of smoke liquid gathering into large drops of smoke liquid after the electronic device 1000 times of use to cause the channel to be blocked, and the user experience is good.

[0047] When the light source 20 is in an on state, that is, the first photoreversible affinity-repellent layer 12 is in an illuminated state, the contact angle of the smoke liquid on the first photoreversible affinity-repellent layer 12 becomes smaller, the first photoreversible affinity-repellent layer 12 is lyophilic to the smoke liquid, and has a good wetting property for the smoke liquid. The smoke liquid can quickly spread on the first photoreversible affinity-repellent layer 12 and be heated and atomized by the heating element 13, thereby achieving an efficient and rapid atomization effect.

[0048] In the embodiment of the present application, the first photoreversible affinity-repellent layer 12 is arranged on the atomized surface 102, and the first photoreversible affinity-repellent layer 12 is illuminated or not illuminated by the light source 20 to control the change of the contact angle of the smoke liquid on the first photoreversible affinity-repellent layer 12, thereby controlling the reversible change between the oleophilic and oleophobic properties of the atomized surface 102 to the smoke liquid, and realizing the effect of "interface switch". In this embodiment, when the light source 20 is in the off state, the electronic device 1000 has the effect of preventing oil leakage, and when the light source 20 is in the on state, the electronic device 1000 has the effect of efficient and rapid atomization, and will not block the channel, thereby improving the user experience.

[0049] In one embodiment, the side 103 of the porous carrier 11 is coated with a second photoreversible affinity layer (not shown). When the smoke liquid flows through the liquid-conducting channel to the second photoreversible affinity layer of the side 103, the second photoreversible affinity layer has oleophobicity to the smoke liquid, thereby squeezing the smoke liquid to flow along the liquid-conducting channel toward the atomization surface 102, thereby improving the efficiency of the smoke liquid being transported to the atomization surface 102, and further facilitating the improvement of the atomization efficiency of the smoke liquid. It is understandable that in other embodiments, the side 103 may not be coated with the second photoreversible affinity layer, or may be coated with a lyophobic layer.

[0050] Among them, the material of the second photoreversible affinity-repellent layer has the same material properties as the first photoreversible affinity-repellent layer, and both are photoreversible affinity-repellent layer materials. Photoreversible affinity-repellent layer materials include but are not limited to arrays of metal oxide nanorods and high molecular polymer materials. Arrays of metal oxide nanorods include but are not limited to zinc oxide nanorods, and high molecular polymer materials include but are not limited to high molecular polyisopropylacrylamide. The above-mentioned photoreversible affinity-repellent layer materials have different contact angles with smoke liquid in different environments, showing lyophobicity in a darkroom environment and lyophilicity under ultraviolet light irradiation, showing that they can achieve reversible changes between oleophobicity and lipophilicity under light conditions.

[0051] In this embodiment, the materials of the first photoreversible affinity-repellent layer 12 and the second photoreversible affinity-repellent layer are both high molecular weight polyisopropylacrylamide, and in other embodiments, they can also be other photoreversible affinity-repellent layer materials that can achieve reversible changes in oleophilicity and oleophobicity under light conditions. The first photoreversible affinity-repellent layer 12 and the second photoreversible affinity-repellent layer can be prepared by vacuum coating, coating or hydrothermal method.

[0052] It can be understood that, in other embodiments, the material of the first photoreversible affinity-phobic layer can be adjusted according to the type of liquid to be atomized, so that when the light source is not irradiating the first photoreversible affinity-phobic layer, the liquid is difficult to condense on the first photoreversible affinity-phobic layer, and when the light source is irradiating the first photoreversible affinity-phobic layer, the first photoreversible affinity-phobic layer becomes lyophilic to the liquid, and the liquid spreads rapidly on the first photoreversible affinity-phobic layer.

[0053] See also Figure 2 , Figure 2 The schematic diagram of the structure of the electronic cigarette 2000 in the second embodiment of the present application is shown. The atomizer assembly 200 in the electronic cigarette 2000 in this embodiment is the same as the atomizer assembly 200 in the electronic device 1000 in the first embodiment.

[0054] The electronic cigarette 2000 includes a housing 100, an atomizer assembly 200, a power connector 300 and a first seal 400.

[0057] In this embodiment, the housing 100 includes a first housing 110, a second housing 120, and a second sealing member 130. The second housing 120 is sleeved in the first housing 110.

The second end 112 has a second opening, and the second shell 120 is installed in the second part of the chamber and is plugged and fixed in the second opening to encapsulate the chamber of the first shell 110.

An air inlet channel 530 is provided on the bottom plate 122, and the air inlet channel 530 passes through the bottom plate 122 and is connected to the atomizing chamber 520.

Specifically, the air enters the atomizing chamber 520 from the air inlet channel 530, passes through the atomizing core 10 in the atomizer assembly 200, and finally flows out through the air outlet channel 510.

[0060] See also Figure 4 , Figure 4 Shows Figure 2 The schematic diagram of the structure of the atomizer assembly 200 and the power connector 300 in the electronic cigarette 2000 is shown. The atomizer assembly 200 in the electronic cigarette 2000 of this embodiment is the same as the atomizer assembly 200 in the electronic device 1000 of the first embodiment, including an atomizer core 10 and a light source 20, the atomizer core 10 and the light source 20 are installed in the second housing 120, and the power connector 300 is electrically connected to the heating element in the atomizer core 10.

[0061] Specifically, in this embodiment, the atomizer core 10 is carried on the second shell 120. The atomizer core 10 includes a porous carrier, a first photoreversible affinity layer and a heating element, a porous carrier liquid guide surface 101, an atomization surface 102 and a side surface 103, the liquid guide surface 101 and the atomization surface 102 are arranged opposite to each other, and the side surface 103 is connected between the liquid guide surface 101 and the atomization surface 102. The liquid guide surface 101 faces the liquid storage tank 114, and the atomization surface 102 and the second shell 120 are enclosed to form an atomization chamber 520. The porous carrier is provided with a liquid guide channel, which is connected to the liquid storage tank 114, and the smoke liquid can flow from the liquid storage tank 114 to the atomization surface 102 of the porous carrier through the liquid guide channel.

[0062] The atomizing surface 102 is covered with a first photoreversible affinity layer, and the side surface 103 is covered with a second photoreversible affinity layer. In this embodiment, the first photoreversible affinity layer and the second photoreversible affinity layer are made of the same material. The second photoreversible affinity layer on the side surface 103 is oleophobic to the smoke liquid, and can repel and squeeze the smoke liquid so that the smoke liquid quickly reaches the atomizing surface 102 along the liquid guide channel and is heated and atomized by the heating element. The heating element is installed on the atomizing surface 102, and the heating element atomizes the smoke liquid flowing to the atomizing surface 102 to form smoke in the atomizing cavity 520.

[0063] In this embodiment, an atomizing channel 540 is provided on the porous carrier in the atomizing core 10. The atomizing channel 540 runs through the liquid guide surface 101 and the atomizing surface 102 of the porous carrier, and is connected to the air outlet channel 510 and the atomizing chamber 520. On the one hand, the smoke formed in the atomizing chamber 520 can be inhaled by the user along the atomizing channel 540, the air outlet channel 510 and the first opening 113 in sequence. On the other hand, after the air enters the atomizing chamber 520 from the air inlet channel 530, it can drive the smoke in the atomizing chamber 520 to be inhaled by the user through the air outlet channel 510. By providing the atomizing channel 540 on the porous carrier, the atomizing chamber 520 is directly connected to the air outlet channel 510, shortening the path for the smoke in the atomizing chamber 520 to enter the air outlet channel 510, thereby improving the efficiency of smoke inhalation.

[0064] The light source 20 is installed on the side of the bottom plate 122 of the second shell 120 facing the atomization chamber 520. Specifically, the light source 20 is installed on the fixing plate 125 on the bottom plate 122, and is used to illuminate the first photoreversible affinity layer. In this embodiment, the light source 20 is an ultraviolet lamp, which has two, located on both sides of the fixing plate 125. The ultraviolet lamp and the heating element 13 share a negative electrode, and then a positive electrode is separately connected. When the light source 20 is turned off, the atomization chamber 520 is in a darkroom state, and no light is irradiated on the first photoreversible affinity layer on the atomization surface 102. The first photoreversible affinity layer is oleophobic to the smoke liquid.

[0065] When the light source 20 is turned on, the light emitted by the light source 20 penetrates the atomizing chamber 520 and reaches the surface of the first photoreversible affinity-repellent layer on the atomizing surface 102. The first photoreversible affinity-repellent layer on the atomizing surface 102 reversibly changes from oleophobic to oleophilic to the smoke liquid, so as to facilitate the rapid spreading of the smoke liquid on the first photoreversible affinity-repellent layer on the atomizing surface 102, thereby achieving an efficient and rapid atomization effect. By controlling the on and off of the light source 20, the contact angle change of the smoke liquid on the first photoreversible affinity-repellent layer is controlled, thereby controlling the reversible change between the oleophilic and oleophobic properties of the atomizing surface 102 to the smoke liquid, thereby controlling the atomization effect of the smoke liquid, and achieving the effect of an "interface switch".

[0066] The power connector 300 includes an electrical connector 310 and a conductive nail 320. The electrical connector 310 is connected to the heating element in the atomizer core 10, and the conductive nail 320 is connected to the electrical connector 310. The electrical connector 310 forms an electrical connection relationship between the heating element and the conductive nail 320 so that the power supply device supplies power to the heating element. Specifically, the conductive nail 320 passes through the through hole 124 and extends to connect with the electrical connector 310. In this embodiment, the electrical connector 310 includes a first section 311 and a second section 312. A portion of the first section 311 is buried in the porous carrier in the atomizer core 10 and connected to the heating element, and the second section 312 is connected to the conductive nail 320. The power supply device can be connected to the conductive nail 320 to supply power to the heating element in the atomizer core 10, and the atomizer core 10 and the light source 20 are connected to the power supply device in parallel.

[0067] See also Figure 5 , Figure 5 Shows Figure 2 A schematic structural diagram of the first sealing component 400 in the electronic cigarette 2000 is shown.

[0068] The first seal 400 is installed between the porous carrier and the first shell 110. Specifically, the first seal 400 is sleeved on the outer surface of the porous carrier in the atomizer core 10, and the first seal 400 is clamped between the porous carrier and the first shell 110, so as to seal the porous carrier of the atomizer core 10 and the first shell 110 tightly.

[0069] In this embodiment, the first seal 400 has a first portion 410 and a second portion 420 extending from the first portion 410 to the inner wall of the atomization channel 540 of the porous carrier. The first portion 410 covers the outer surface of the porous carrier, and the second portion 420 covers the inner wall of the atomization channel 540.

[0070] The first part 410 is provided with a through hole 411, which penetrates the first part 410 to expose the liquid guide surface 101 of the porous carrier. The through hole 411 is respectively connected with the liquid storage tank 114 and the liquid guide channel of the porous carrier, so that the smoke liquid in the liquid storage tank 114 passes through the through hole 411 and flows along the liquid guide channel of the porous carrier to the heating element on the atomization surface 102 for atomization.

[0071] The second part 420 has a step 421, and the end of the tubular part 511 in the first shell 110 facing the second end 112 has a plug-in part, and the plug-in part is in the shape of a boss. The plug-in part of the tubular part 511 is inserted into the atomization channel 540 and abuts against the second part 420, so that the first shell 110 and the first sealing member 400 are firmly fixed. Specifically, the plug-in part of the tubular part 511 abuts against the step 421, and the boss-shaped plug-in part cooperates with the step 421 to improve the reliability of the tubular part 511 fixing and positioning the first sealing member 400.

[0072] In this embodiment, the first seal 400 is interference-fitted with the inner wall of the first shell 100, and the first seal 400 is interference-fitted with the porous carrier. The first seal 400 is sleeved on the porous carrier of the atomizer core 10 to form an integral structure, and the integral structure is mounted on the second shell 120. Specifically, the first seal 400 is carried on the second shell 120, and the porous carrier of the atomizer core 10 is loaded in the first seal 400.

[0073] The electronic cigarette 2000 provided in this embodiment has a first photoreversible affinity-repellent layer disposed on the atomizing surface 102 of the porous carrier in the atomizing core 10. When the light source 20 is in the off state, the first photoreversible affinity-repellent layer on the atomizing surface 102 is in a darkroom state and has oleophobicity to the smoke liquid. The contact angle of the smoke liquid on the first photoreversible affinity-repellent layer on the atomizing surface 102 is large, which can prevent the smoke liquid from leaking. At the same time, it is difficult for the smoke liquid droplets to accumulate on the surface of the atomizing cavity 520 for a long time, thereby avoiding the blockage of the channel 500 by the smoke liquid, thereby avoiding the problem of the smoke liquid on the channel 500 being inhaled into the mouth of the user.

[0074] When the light source 20 is in the on state, the first photoreversible affinity-repellent layer on the atomizing surface 102 is in the illuminated state, and the first photoreversible affinity-repellent layer reversibly changes from oleophobic to oleophilic to the smoke liquid. The smoke liquid can quickly flow to the atomizing surface 102 and quickly spread on the first photoreversible affinity-repellent layer on the atomizing surface 102. The heating element on the atomizing surface 102 can quickly atomize the smoke liquid, thereby achieving an efficient and rapid atomization effect.

[0075] In the electronic cigarette 2000 provided in this embodiment, a second photoreversible affinity-repellent layer is provided on the side 103 of the porous carrier in the atomization core 10. When the smoke liquid reaches the side 103 through the liquid-conducting channel of the porous carrier, the second photoreversible affinity-repellent layer on the side 103 has oleophobicity to the smoke liquid, and can repel and squeeze the smoke liquid, so that the smoke liquid quickly reaches the atomization surface 102 along the liquid-conducting channel to be heated and atomized by the heating element. It can be understood that in other embodiments, the side 103 may not be coated with the second photoreversible affinity-repellent layer, or may be coated with a lyophobic layer.

[0076] The embodiment of the present application can accelerate the arrival of the smoke liquid along the liquid guide channel to the atomization surface 102 for atomization by setting a second photoreversible affinity layer on the side 103 of the atomization core 10, and can control the reversible change of the oleophobicity and oleophilicity of the smoke liquid on the surface of the atomization surface 102 by controlling the closing and opening of the light source 20, thus playing the role of an "interface switch". In this embodiment, when the light source 20 is in the closed state, the electronic cigarette 2000 has the effect of preventing oil leakage, and when the light source 20 is in the open state, the electronic cigarette 2000 has the effect of efficient and rapid atomization, and will not block the channel 500, thereby improving the user experience.

[0077] What is disclosed above is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
