Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic atomizer, more particularly, the present application relates to an electronic atomizer with a liquid leakage prevention structure. BACKGROUND

[0002] The existing electronic atomization device generally comprises a battery assembly and an electronic atomizer, a battery is installed in the battery assembly, and the battery supplies power to the atomizer. The atomizer comprises an atomization core installed on an atomization seat. The atomization core comprises a liquid guide and a heating body. When the heating body is powered, it can heat and atomize the solution to be atomized, i.e. the atomization liquid, into an aerosol. The atomization liquid is stored in the liquid storage cavity of the atomizer. The electronic atomization device can be used as an electronic cigarette, a herbal atomization device, a medical atomization device, etc.

[0003] The existing atomization core on the market is made of porous ceramic. The porous ceramic body has a plurality of complexly distributed and non-straight-through micropores. These combined micropores have the function of conducting and permeating the atomization liquid. The atomization liquid generally flows from the liquid storage cavity to the inside of the porous ceramic body and then permeates to the heating body on the lower surface of the porous ceramic body. The heating body generates heat when powered and can heat and atomize the atomization liquid permeated from the porous ceramic body. In the working process of the atomizer, when the user sucks the electronic atomizer, the atomization liquid in the liquid storage cavity is continuously consumed, and a certain degree of vacuum is generated in the liquid storage cavity. When the vacuum degree in the liquid storage cavity accumulates to a certain extent, the atomization liquid stored therein is sucked back, so it is difficult to permeate out through the porous ceramic body, resulting in a lack of atomization liquid when the heating body works, so that the atomization amount is continuously reduced and even causes dry burning of the atomization core, leading to its ablation and damage.

[0004] In addition, the existing atomizer is prone to leakage of droplets of atomization liquid and uneven temperature inside the atomizer, which can cause condensation of the atomized electronic cigarette smoke on the inner wall and condense into small droplets. The air inlet channel and smoke discharge channel in the existing atomizer are generally arranged on the same vertical axis, so these small droplets are easily overflowed or leaked back through the airflow channel, thereby contaminating the circuit or being carried out by the user, which can be easily inhaled into the user's mouth, resulting in poor user experience.

[0049] As shown, Figure 4 , Figures 7-8 The sealing cover 21 is made of soft material and covers the upper half of the atomization support 22, and is configured to seal the gap between the atomization support 22 and the inner wall of the shell 1, and to seal the gap between the mist outlet hole 226 and the mist discharge pipe 11, the sealing cover 21 is provided with a liquid inlet through hole 214 corresponding to the liquid inlet port 224, and is provided with a sealing pipe 216 corresponding to the mist outlet hole 226. The sealing cover 21 is made of soft material, for example, silica gel material, which has good sealing performance.

[0050] Specifically, the sealing cover 21 is provided with an outer side wall 210, which seals the gap between the atomization support 22 and the inner wall of the shell 2. The sealing cover 21 is also provided with an air inlet pipe 244, which is arranged in the gap between the mist outlet hole 226 and the mist discharge pipe 11.

[0051] As shown in Figure 4 , Figure 9 , Figure 10 The upper part of the bottom cover 24 is sleeved on the lower part of the atomization support 22. The bottom part of the bottom cover 24 includes a first cavity 241, a second cavity 242, and a third cavity 243, which are arranged transversely and have open upper ends and closed lower ends. The first cavity 241, the second cavity 242, and the third cavity 243 are respectively connected with the air inlet cavity 221, the atomization cavity 222, and the liquid collecting cavity 223. A first gap 246 is arranged between the first cavity 241 and the second cavity 242, and a second gap 247 is arranged between the second cavity 242 and the third cavity 243. The bottom part of the first cavity 241 is provided with the air inlet pipe 244, which communicates with the air inlet cavity 221.

[0052] Specifically, the bottom cover 24 is provided with a bottom plate wall 240 and a surrounding wall 248. The lower part of the atomization support 22 is sleeved on the inner side of the surrounding wall 248. The inner lower part of the surrounding wall 248 and the upper part of the bottom plate wall 240 are provided with a boss 249 corresponding to the lower part of the outer vertical wall 228 and the inner vertical wall 229 of the atomization support. The boss 249 is a protruding table-shaped body or a short surrounding wall. The first cavity 241, the second cavity 242, and the third cavity 243 are respectively formed by the boss 249.

[0053] The second cavity 242 of the bottom cover is covered with an air flow baffle 25, which separates the atomization cavity 222 and the second cavity 242. The air flow baffle 25 is provided with an inclined bottom groove 250 in the middle, and the bottom low point of the inclined bottom groove 250 is provided with a baffle through hole 251 downward. The lower part of the air flow baffle 25 is provided with a liquid suction port 253 at the second gap 247, so that the condensed liquid or small droplets falling to the lower part of the air flow baffle 25 can flow to the liquid suction block 27 through the liquid suction port 253. The outer edge 252 of the air flow baffle 25 is arranged on the boss 249 which constitutes the second cavity, and can be downwardly buckled and pressed by the inner vertical wall 229 of the atomization support, so that the bottom edge of the atomization cavity 222 is sealed to prevent air leakage or liquid leakage. The air flow baffle 25 is provided with an inclined bottom groove 250, which can be used to collect the condensed liquid or small droplets falling from the aerosol condensed on the wall of the atomization cavity 222 and the smoke outlet pipe 11 after being cooled. The condensed liquid flows to the low-lying side on the inclined bottom surface of the inclined bottom groove 250 and flows into the baffle through hole 251, and then further falls and flows to the liquid suction block 27 arranged in the first cavity 241 and the third cavity 243, and is adsorbed or collected by the liquid suction block 27, so as to avoid the condensed liquid being sucked into the air flow and being sucked into the mouth. When the suction air flow enters the atomization cavity 222 from the air inlet cavity 221, it will be blocked by the air flow baffle 25 and only pass through the baffle through hole 251, so that even if there is condensed liquid or small droplets below the air flow baffle 25, it is difficult to be disturbed and carried back to the atomization cavity 222, so as to avoid the condensed liquid being sucked into the air flow and being sucked into the mouth.

[0054] The first cavity 241 and the third cavity 243 of the bottom cover are filled with liquid suction blocks 27, and the liquid suction block 27 of the first cavity 241 is provided with an air vent 270 at the first gap 246 to communicate the air inlet cavity 221 and the first gap 246, and further communicate the air inlet cavity 221 and the atomization cavity 222.

[0055] The bottom of the second cavity 242 of the bottom cover is provided with two columnar electrodes 26, which abut against the atomization core 23 upwardly. The columnar electrodes 26 are respectively connected to the two end electrodes of the following heating body 233, so that the heating body 233 can be electrified and heated.

[0056] As Figure 11As shown, the atomizing core 23 comprises a soft liquid guide 231, a porous ceramic body 232 and a heating body 233 which are connected and arranged in sequence, and the soft liquid guide 231 is arranged upwardly and communicates with the liquid storage cavity 13. The soft liquid guide 231 is made of soft and good adsorption material, for example, organic cotton, inorganic cotton, glass fiber, non-woven fabric and the like. The porous ceramic body 232 is made of porous ceramic material and has many small pores for permeating and adsorbing the atomizing liquid. The gaps or pores in the soft liquid guide 231 are more and larger than those in the porous ceramic body 232, so that the liquid guiding capacity or speed of the soft liquid guide 231 is better and faster than that of the porous ceramic body 232. In this way, the soft liquid guide can be used as a buffer material between the liquid storage cavity and the porous ceramic body, so that the atomizing liquid can be fully supplied to the porous ceramic body, and the atomizing liquid can be prevented from flowing to the porous ceramic body too much and too fast, and the atomizing liquid can be prevented from leaking.

[0057] As shown in Figure 4 The working principle of the electronic atomizer with the liquid leakage prevention structure is as follows: when a user inhales from the suction port, a negative pressure is generated in the electronic atomizer, the cylindrical electrode 26 is electrified to heat the atomizing core 23, at the same time, external air enters the air inlet cavity 221 from the air inlet pipe 244 upwardly, then turns downwardly through the air passage 270 of the liquid suction block 27 and the first gap 246, enters the lower part of the airflow baffle 25, then turns upwardly through the baffle through hole 251, and then enters the atomizing cavity 222. At this time, the atomizing liquid in the liquid storage cavity 13 penetrates downwardly through the liquid inlet through hole 214 in the sealing cover and the liquid inlet 224 of the atomizing support, enters the soft liquid guide 231 and the porous ceramic body 232 of the atomizing core, and penetrates out from the lower surface of the porous ceramic body 232. The heating body 233 is electrified and heated at this time, so that the atomizing liquid is heated and evaporated, and aerosol, i.e. electronic cigarette smoke, is generated from the lower surface of the porous ceramic body 232, and then diffuses to the atomizing cavity 222. At this time, the external air has been inhaled into the atomizing cavity 222 and forms an inhalation airflow. The electronic cigarette smoke is further inhaled into the mist discharging pipe 11 under the driving of the inhalation airflow, and finally inhaled into the user's mouth through the suction port 10. Figure 4 The continuous hollow arrow in the figure indicates the route and direction, i.e. the route and direction of the airflow entering the electronic atomizer and the smoke flowing out of the electronic atomizer. Figure 4 The continuous solid arrow in the figure indicates the route and direction, i.e. the route and direction of the atomizing liquid flowing or penetrating.

[0058] As shown in Figure 4As shown, the electronic atomizer of the present application has a transversely separated air inlet cavity 221 and atomization cavity 222, external air enters from the air inlet pipe 244 at the bottom, air inlet cavity 221, air vent 270, first gap 246, baffle through hole 251, and then enters the atomization cavity 222, and passes through multiple meandering airflow paths, so even if the atomization core, the atomization cavity has leaked atomization liquid or condensed liquid droplets in the mist discharge pipe 11, it is not easy to flow out from the air inlet pipe 244 in the reverse direction through the above-mentioned meandering airflow path, avoiding the leakage of liquid droplets, even if the leakage flows into the battery assembly connected with the atomizer to further pollute and corrode the internal circuit and cause failure.

[0059] As shown, Figure 4 As shown, the electronic atomizer of the present application, in the atomization cavity 222, the atomization core 23 and the mist outlet hole 226 are arranged transversely on the airflow passage, instead of being arranged linearly on the axis of the airflow passage, so that the atomization liquid is first dispersed in the atomization cavity 222 after being heated and evaporated into aerosol at the bottom of the atomization core 23, and can be fully disturbed by the forward collision of the upward airflow entering through the baffle through hole 251, so that the temperature of the aerosol or electronic cigarette smoke can be reduced, and then inhaled into the user's mouth through the mist discharge pipe 11, which can prevent the high temperature of the inhaled smoke or suction port 10 from scalding the mouth and avoid causing harm to the user.

[0060] As shown, Figure 13 As shown, when the user smokes, electronic cigarette smoke is generated in the atomization cavity 222 and further flows out through the mist discharge pipe 11. Since the electronic cigarette smoke is a heated and evaporated steam mist, some of the steam mist will inevitably condense into small droplets on the inner walls of the atomization cavity 222 and the mist discharge pipe 11. When the small droplets accumulate, they will drip down along the inner walls of the atomization cavity 222 and the mist discharge pipe 11. At this time, the inclined bottom groove 250 of the airflow baffle 25 will collect these small droplets, which will then flow to the bottom of the second cavity 242 through the baffle through hole 251 at the bottom low point of the inclined bottom groove 250, and then further flow to the liquid suction block 27 through the first gap 246 and the second gap 247 on both sides, and finally be absorbed by the liquid suction block 27. In this way, the small droplets condensed in the electronic atomizer of the present application will not be inhaled into the mouth when the user smokes, resulting in poor user experience. Figure 13 The continuous solid arrow in the middle indicates the route and direction of the flow of small droplets condensed in the electronic atomizer of the present application and absorbed by the liquid suction block.

[0061] As shown, Figure 14 , Figure 15As shown, when the user smokes for a long time, the atomized liquid in the liquid storage cavity 13 is continuously consumed, and when the liquid storage cavity 13 has good sealing performance, the volume of the consumed atomized liquid is emptied, and if the incoming air is not filled, a vacuum state is easily formed. When the liquid storage cavity generates a vacuum state, due to the reverse negative pressure, the atomized liquid is difficult to penetrate into the atomizing core, and when the heating body 233 of the atomizing core works, the amount of smoke generated is continuously reduced due to the lack of atomized liquid, and even the atomizing core is dry-burned due to the cut-off of the atomized liquid, and is damaged by burning and ablation. The electronic atomizer of the present application is provided with a transversely winding strip-shaped groove 227 on the upper outer wall of the atomizing support 22, the strip-shaped groove is communicated with the liquid inlet 224, the lower end of the strip-shaped groove 227 is communicated with the air inlet cavity 221, the strip-shaped groove 227 and the side wall of the sealing cover form a gas return channel, the gas return channel can guide the air in the air inlet cavity 221 to the liquid storage cavity 13, and the bottom inlet of the gas return channel is formed in the air inlet cavity to form a gas return port 2270. Therefore, when a vacuum is generated in the liquid storage cavity 13, the air in the air inlet cavity 221 can enter the gas return channel through the gas return port 2270, and finally enter the liquid storage cavity 13 through the liquid inlet 224, and the slowly entering air can gradually eliminate the vacuum state in the liquid storage cavity 13. In this way, the atomized liquid is easily exuded from the porous liquid guide to the heating body, the atomized liquid supply is rapid and timely, and the phenomenon that the amount of smoke is continuously reduced due to the lack of atomized liquid when the heating body works, and even the dry-burning of the atomizing core due to the cut-off of the atomized liquid and the damage of the atomizing core by burning and ablation are avoided, and the normal and stable work of the atomizer is ensured. Figure 14 、 Figure 15 The continuous hollow arrow shown in the middle indicates the route and direction of the air in the electronic atomizer of the present application entering the liquid storage cavity through the gas return channel to eliminate the vacuum state.

[0062] As shown in the middle, Figure 16 、 Figure 17 As shown in the middle, when the pressure in the liquid storage cavity 13 is greater than the pressure in the air inlet cavity 221, although the gas return channel is very small, the atomized liquid in the liquid storage cavity 13 cannot be completely prevented from flowing back to the air inlet cavity through the gas return channel. That is, the atomized liquid can flow back from the liquid storage cavity 13 to the gas return port 2270 through the strip-shaped groove 227, and drop into the air inlet cavity 221, and at this time, since the liquid suction block 27 has been installed on the lower surface of the air inlet cavity 221 to absorb and store the liquid drops of the dropped atomized liquid, the atomized liquid dropped out can be prevented from being sucked into the mouth through the suction air flow when the user smokes, and the bad use experience is avoided.

[0063] The above description is only the preferred embodiment of the present application, and the above specific embodiment is not a limitation on the present application.
