Description

Technical Field

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

[0002] There are dozens of carcinogens in tobacco smoke, such as tar, which is very harmful to human health. The smoke fills the air and forms secondhand smoke, which can also cause harm to the body when inhaled by people around. Therefore, smoking is prohibited in most public places. Electronic atomizers have a similar appearance and taste to ordinary cigarettes, but usually do not contain tar, suspended particles and other harmful ingredients in cigarettes. Therefore, electronic atomizers are widely used as substitutes for cigarettes.

[0003] An electronic atomization device usually includes an atomizer and a power supply. When the electronic atomization device stops being used, the oil or condensate stored in the atomizer will leak from the bottom of the atomizer to the power supply. The leaked oil or condensate will corrode the power supply, thereby affecting the service life of the power supply. Summary of the invention

[0004] A technical problem solved by the present invention is how to prevent the atomizer from leaking liquid.

[0006] In one embodiment, the bottom cover is also provided with an air guide cavity, the bottom cover has a mounting surface defining a portion of the air guide cavity and disposed toward the input port, the bottom cover also includes a boss located in the air guide cavity, one end of the boss is connected to the mounting surface, the other end of the boss protrudes relative to the mounting surface and has a free end surface, the free end surface is spaced apart from the mounting surface, the air inlet channel is provided in the boss, the output port is located at the free end surface, and external gas enters the input port through the output port and the air guide cavity in sequence. In this way, the output port on the free end surface can be higher than the mounting surface by a certain distance, thereby preventing the liquid level of the leaked liquid from being flush with the free end surface, preventing the leaked liquid from entering the air inlet channel through the output port and flowing out of the entire atomizer, thereby preventing the atomizer from leaking.

[0007] In one embodiment, the bottom cover further includes a convex strip, the convex strip is connected to the mounting surface and protrudes relative to the mounting surface, and a liquid storage tank capable of storing liquid is formed between the convex strips; and / or, the mounting surface is recessed to form a liquid storage tank capable of storing liquid. By providing the liquid storage tank, the space of the bottom cover for storing leaked liquid can be increased.

[0008] In one embodiment, the input port is closer to the mounting surface than the output port, which can effectively prevent the leakage liquid that deviates from the straight dripping trajectory and forms a drifting flow into the input hole, thereby preventing leakage.

[0009] In one embodiment, a sealing member is further included, the sealing member covers the air guide cavity, the air inlet channel includes a first air channel opened on the sealing member, the input port is located in the first air channel, the sealing member has an upper surface arranged toward the atomizer core, and the upper surface is provided with a sink capable of storing liquid.

The guide port on the upper end surface can be made higher than the upper surface by a certain distance, thereby preventing the liquid level of the leaked liquid from being flush with the upper end surface, and preventing the leaked liquid from dripping from the first gas channel to the liquid storage tank of the bottom cover through the guide port.

[0011] In one embodiment, the seal has a lower surface disposed toward the bottom cover, the seal includes a lower boss, one end of the lower boss is connected to the lower surface, the other end of the lower boss protrudes relative to the lower surface, a portion of the first air passage is located in the lower boss, the number of the bosses is two, and the lower boss is sandwiched between the two bosses.

[0012] In one embodiment, the other end of the lower boss has a lower end surface, the lower end surface is spaced apart from the lower surface, and the input port is located on the lower end surface.

[0013] In one embodiment, along the direction from the atomizer core to the bottom cover, the distance between the two bosses and the cross-sectional size of the lower boss gradually decrease. The guiding effect of the wedge-shaped lower boss can improve the installation efficiency and stability of the seal.

[0016] An electronic atomization device comprises a power source and any one of the above-mentioned atomizers, wherein the atomizer is detachably connected to the power source. When the liquid in the atomizer is consumed, a new atomizer can be replaced to cooperate with the power source, so that the power source can be recycled.

[0017] A technical effect of an embodiment of the present invention is that: for the leakage liquid formed by the leaked liquid on the atomizer core and the condensed liquid in the entire air intake channel, when the leakage liquid flows out from the input port of the air intake channel, since the orthographic projection of the input port on the bottom cover is completely outside the outline of the output port, the leakage liquid can be effectively prevented from entering the air intake channel from the input port through the output port, and finally the leakage liquid is prevented from flowing out of the entire atomizer from the air intake channel, thereby preventing the atomizer from leaking.

[0033] See also Figure 1 , Figure 2 and Figure 3An atomizer 10 provided by an embodiment of the present invention is used to atomize an aerosol-generating matrix such as a liquid to form smoke that can be inhaled by a user. The atomizer 10 includes an atomizer core 100, a bottom cover 200, a seal 300 and a shell assembly 400. The bottom cover 200 is arranged at the end of the shell assembly 400, and the seal 300 and the atomizer core 100 are both arranged inside the shell assembly 400. The atomizer core 100 is located above the bottom cover 200, and the seal 300 is located between the bottom cover 200 and the atomizer core 100. An inhalation channel 600 is provided on the shell assembly 400 and the seal 300, and the inhalation channel 600 has an input port 611. When the atomizer 10 is working, the gas first flows into the entire inhalation channel 600 from the input port 611. The bottom cover 200 is provided with an air inlet channel 500 , which connects the air inlet channel 600 and the outside. The air inlet channel 500 has an output port 510 corresponding to the input port 611 . When the atomizer 10 is working, the gas in the air inlet channel 500 finally flows out from the output port 510 .

[0034] The air inhalation channel 600 includes a first air channel 610 and a second air channel 620. The first air channel 610 is provided on the sealing member 300, and the second air channel 620 is provided on the housing assembly 400. The second air channel 620 runs through the outer surface of the housing assembly 400, thereby forming a suction nozzle 621 on the outer surface. The suction nozzle 621 is located at one end of the housing assembly 400 away from the bottom cover 200, and the second air channel 620 is connected to the outside through the suction nozzle 621. The user can inhale the smoke generated by the atomizer 10 by contacting the suction nozzle 621. A liquid storage cavity is also provided in the housing assembly 400, and the liquid storage cavity is used to store liquid.

[0035] In some embodiments, at least a portion of the atomizer core 100 is located in the second air channel 620, and the liquid storage chamber can supply liquid to the atomizer core 100. The atomizer core 100 includes a heat-generating component and a liquid-permeable component, wherein the heat-generating component can be a metal wire, a resistor material, etc., and the liquid-permeable component can be a ceramic material, various fiber materials, cotton or non-woven fabric materials, etc. The atomizer core 100 can atomize the liquid provided by the liquid storage chamber to form smoke, and the smoke can be inhaled by the user through the second air channel 620.

[0036] See also Figure 4 , Figure 6 and Figure 8In some embodiments, an air guide cavity 230 is provided on the bottom cover 200, and the air guide cavity 230 is actually an open cavity. The bottom cover 200 has a mounting surface 210, and the mounting surface 210 is arranged toward the atomizer core 100. In layman's terms, the mounting surface 210 is actually the bottom wall surface of the air guide cavity 230. The bottom cover 200 also includes a boss 220, which is accommodated in the air guide cavity 230. The boss 220 is vertically arranged relative to the mounting surface 210, one end of the boss 220 (hereinafter collectively referred to as the lower end of the boss 220) is fixedly connected to the mounting surface 210, and the other end of the boss 220 (hereinafter collectively referred to as the upper end of the boss 220) protrudes a certain height relative to the mounting surface 210. The upper end of the boss 220 has a free end surface 223, and the free end surface 223 is spaced apart from the mounting surface 210 in the vertical direction of the boss 220, so that the free end surface 223 is located above the mounting surface 210. The air inlet channel 500 is arranged in the boss 220, and the lower end of the air inlet channel 500 passes through the outer surface of the bottom cover 200 and is directly connected to the outside, and the upper end of the air inlet channel 500 passes through the free end surface 223, so that the above-mentioned output port 510 is formed on the free end surface 223. Obviously, the output port 510 of the air inlet channel 500 is arranged above the mounting surface 210 and higher than the mounting surface 210. After the external gas enters the air inlet channel 500, the external gas will enter the input port 611 of the air suction channel 600 through the output port 510 and the air guide cavity 230 in sequence.

[0037] A liquid reservoir 241 is formed on the bottom cover 200, and there are many ways to form the liquid reservoir 241. For example, the bottom cover 200 may also include a convex strip 240, the convex strip 240 is connected to the mounting surface 210, the convex strip 240 protrudes a certain height relative to the mounting surface 210, the height of the convex strip 240 protruding relative to the mounting surface 210 is less than the height of the protruding column 220 protruding relative to the mounting surface 210, and the liquid reservoir 241 is formed between two adjacent convex strips 240. For another example, a part of the mounting surface 210 may be recessed downward to a certain depth to form the liquid reservoir 241. For another example, the liquid reservoir 241 may be formed by both providing the convex strip 240 and recessing the mounting surface 210.

[0038] See also Figure 7, the number of the bosses 220 can be two, the sizes of the two bosses 220 can be roughly the same, and each boss 220 is provided with an air inlet channel 500, so the number of the air inlet channel 500 is two, and the air inlet channel 500 can be a circular hole. The two bosses 220 are respectively recorded as the first boss and the second boss, and the first boss is provided with a first inclined surface 221, and the first inclined surface 221 is connected with the free end surface 223 on the first boss to form an obtuse angle. Therefore, in the direction of the atomizer core 100 pointing to the bottom cover 200, that is, in the direction from top to bottom, the distance from the first inclined surface 221 to the central axis of the air inlet channel 500 in the first boss gradually increases. Similarly, the second boss is provided with a second inclined surface 222, and the second inclined surface 222 is connected with the free end surface 223 on the second boss to form an obtuse angle, and the distance from the second inclined surface 222 to the central axis of the air inlet channel 500 in the second boss gradually increases in the direction from top to bottom. The first inclined surface 221 and the second inclined surface 222 are arranged at intervals in the horizontal direction, and the distance between the first inclined surface 221 and the second inclined surface 222 is the distance between the first convex column and the second convex column. From top to bottom, the distance H between the first inclined surface 221 and the second inclined surface 222 gradually decreases, so the distance between the first convex column and the second convex column gradually decreases. According to the actual needs, the number of convex columns 220 can be appropriately increased or decreased, for example, the number of convex columns 220 can be one, three or four.

[0039] See also Figure 3 and Figure 5 In some embodiments, the seal 300 includes a silicone seal, that is, the seal 300 is made of silicone material, which can make the seal 300 have a certain degree of flexibility. The seal 300 can be sleeved on the bottom cover 200, and the seal 300 is squeezed between the bottom cover 200 and the housing assembly 400 at the same time, so that the seal 300 plays a sealing role on the air guide cavity 230.

[0040] See also Figure 7 and Fig. 9The sealing member 300 has an upper surface 310 and a lower surface 320, and the upper surface 310 and the lower surface 320 are oriented in opposite directions, the upper surface 310 is disposed toward the atomizer core 100, and the lower surface 320 is disposed toward the bottom cover 200. The sealing member 300 includes an upper boss 330 and a lower boss 340, the upper boss 330 is connected to the upper surface 310, and the upper boss 330 protrudes upward by a certain height relative to the upper surface 310. For example, the lower end of the upper boss 330 is fixedly connected to the upper surface 310, the upper end of the upper boss 330 protrudes by a certain height relative to the upper surface 310, and the upper end of the upper boss 330 has an upper end surface 331, and the upper end surface 331 is also disposed toward the atomizer core 100, so that the upper end surface 331 and the upper surface 310 are spaced apart in the vertical direction, and the upper end surface 331 is located above the upper surface 310. From top to bottom, the cross-sectional dimension of the upper boss 330 can gradually increase to be in the shape of a platform. Of course, the cross-sectional dimension of the upper boss 330 can remain unchanged to be in the shape of a column. A portion of the first gas channel 610 is located inside the upper boss 330. The first gas channel 610 penetrates the upper end surface 331 to form a guide outlet 612, that is, the guide outlet 612 is located on the upper end surface 331. The first gas channel 610 is connected to the second gas channel 620 through the guide outlet 612. The gas entering the first gas channel 610 finally flows out from the guide outlet 612, so that the gas in the first gas channel 610 flows into the second gas channel 620 through the guide outlet 612.

[0041] The seal 300 may be formed with a sink 311, which is used to store liquid. The sink 311 may be formed in a variety of ways. For example, a portion of the upper surface 310 may be recessed downward to a certain depth to form the sink 311. For another example, the seal 300 may also include a protrusion, which is connected to the upper surface 310, and the protrusion protrudes a certain height relative to the upper surface 310. The height of the protrusion relative to the upper surface 310 is less than the height of the upper boss 330 relative to the upper surface 310, and the sink 311 is formed between two adjacent protrusions. For another example, the sink 311 may be formed by both providing a protrusion and recessing the upper surface 310.

[0042] The lower boss 340 is connected to the lower surface 320, and the lower boss 340 protrudes downward by a certain height relative to the lower surface 320. For example, the upper end of the lower boss 340 is fixedly connected to the lower surface 320, and the lower end of the lower boss 340 protrudes by a certain height relative to the lower surface 320. The lower end of the lower boss 340 has a lower end surface 341, and the lower end surface 341 is arranged toward the bottom cover 200, so that the lower end surface 341 and the lower surface 320 are arranged at intervals in the vertical direction, and the lower end surface 341 is located below the lower surface 320. Along the direction from top to bottom, the cross-sectional dimension h of the lower boss 340 can be gradually reduced to be in the shape of a table, and of course, the cross-sectional dimension of the lower boss 340 can remain unchanged to be in the shape of a column. Another portion of the first air channel 610 is located in the lower boss 340 . The first air channel 610 penetrates the lower end surface 341 to form the input port 611 . The first air channel 610 is connected to the air guide cavity 230 of the bottom cover 200 through the input port 611 .

[0043] The number of the upper boss 330 and the lower boss 340 can be one. During the installation process of the seal 300 and the bottom cover 200, the lower boss 340 is sandwiched in the gap between the two bosses 220, so that the lower boss 340 is in contact with the first inclined surface 221 and the second inclined surface 222 at the same time. Therefore, the two bosses 220 play a good positioning role in the installation of the seal 300, and also improve the stability and reliability of the installation of the seal 300. At the same time, along the direction from top to bottom, the cross-sectional size of the lower boss 340 gradually decreases, and the spacing between the first inclined surface 221 and the second inclined surface 222 decreases. During the installation process, the lower boss 340 can be smoothly inserted into the gap between the first inclined surface 221 and the second inclined surface 222, ensuring that the two bosses 220 smoothly form a sandwiching effect on the lower boss 340. When the seal 300 is installed, the input port 611 is closer to the installation surface 210 relative to the output port 510. In other words, the input port 611 is located below the output port 510. At the same time, the orthographic projection of the input port 611 on the bottom cover 200 is located outside the outline of the output port 510, so that the input port 611 and the output port 510 are completely misaligned in the horizontal direction. Fig.12 , the distance R between the orthographic projection 611a of the input port 611 on the bottom cover 200 and the orthographic projection 510a of the output port 510 on the bottom cover 200 is greater than zero. At this time, the orthographic projection 611a of the input port 611 and the orthographic projection 510a of the output port 510 are in a "separated" state. Fig.13, the distance R between the orthographic projection 611a of the input port 611 on the bottom cover 200 and the orthographic projection 510a of the output port 510 on the bottom cover 200 is equal to zero. At this time, the orthographic projection 611a of the input port 611 and the orthographic projection 510a of the output port 510 are in a "tangent" state. The above-mentioned "separated" and "tangent" states can also make the input port 611 and the output port 510 in a misaligned state in the horizontal direction. In other embodiments, the input port 611 and the output port 510 can be at the same height relative to the mounting surface 210, and the input port 611 can also be above the output port 510.

[0044] See also Figure 3 , Figure 6 and Figure 7 When the user draws air at the mouthpiece 621, the external gas first enters the air inlet channel 500, then enters the first airway 610 through the outlet 510, the air guide cavity 230 and the input port 611 in sequence, and then enters the second airway 620 from the outlet 612 to carry the smoke out of the mouthpiece 621. Therefore, the flow trajectory of the gas is roughly a "maze-like" trajectory. For the leaked liquid formed by the liquid leaking from the atomizer core 100 and the condensed liquid in the entire air inlet channel 600, when the leaked liquid flows out from the input port 611 of the first airway 610, since the positive projection of the input port 611 on the bottom cover 200 is completely outside the outline of the output port 510, it can effectively prevent the leaked liquid from entering the air inlet channel 500 from the input port 611 through the output port 510, and finally prevent the leaked liquid from flowing out of the entire atomizer 10 from the air inlet channel 500, thereby preventing the atomizer 10 from leaking. Of course, when the orthographic projection 611a of the input port 611 and the orthographic projection 510a of the output port 510 are in the above-mentioned "separated" state or "tangent" state, the atomizer 10 can also be prevented from leaking.

[0045] Since a liquid storage tank 241 is formed on the bottom cover 200, the leaked liquid dripping from the input port 611 will be stored in the liquid storage tank 241. When the leaked liquid in the liquid storage tank 241 reaches saturation, the leaked liquid can overflow into the air guide cavity 230, so both the liquid storage tank 241 and the air guide cavity 230 can store the leaked liquid. In addition, the free end surface 223 of the protruding column 220 is located above the mounting surface 210, so that the output port 510 on the free end surface 223 is higher than the mounting surface 210 by a certain distance, thereby preventing the liquid level of the leaked liquid in the liquid storage tank 241 and the air guide cavity 230 from being flush with the free end surface 223, and preventing the leaked liquid from entering the air inlet channel 500 through the output port 510 and flowing out of the entire atomizer 10, thereby preventing the atomizer 10 from leaking.

[0046] For the leaked liquid dripping from the input port 611, when the dripping trajectory of the leaked liquid is a straight line extending in the vertical direction, since the input port 611 and the output port 510 are completely misaligned, it is obvious that the leaked liquid will directly fall into the liquid storage tank 241. When the leaked liquid deviates from the straight dripping trajectory and forms drifting, since the lower boss 340 is sandwiched between the two convex columns 220, and the input port 611 is located below the output port 510, the convex columns 220 will form a blocking effect on the leaked liquid, so that the drifting leaked liquid cannot enter the output port 510 and flows into the liquid storage tank 241 along the outer surface of the convex column 220, and finally prevents the drifting leaked liquid from entering the air intake channel 500 from the output port 510 and causing leakage.

[0047] Therefore, a part of the leaked liquid drips from the first air channel 610 through the outlet 510 to the liquid storage tank 241, and the liquid storage tank 241 stores the leaked liquid to prevent leakage. At the same time, since the upper surface 310 of the seal 300 is recessed to form a sink 311, another part of the leaked liquid will not be able to drip into the first air channel 610, and the leaked liquid will directly drip into the sink 311, so that the sink 311 stores the leaked liquid. In addition, the upper end surface 331 of the upper boss 330 is located above the upper surface 310, so that the outlet 612 on the upper end surface 331 is higher than the upper surface 310 by a certain distance, thereby preventing the liquid level of the leaked liquid in the sink 311 from being flush with the upper end surface 331, and preventing the leaked liquid from dripping from the first air channel 610 to the liquid storage tank 241 through the outlet 612. In this way, the amount of leaked liquid stored in the liquid storage tank 241 and the air guide cavity 230 will not be too much, and the liquid level of the leaked liquid will not be flush with the free end surface 223 due to the excessive amount of leaked liquid, and finally the leaked liquid will be prevented from entering the air inlet channel 500 from the output port 510 and causing leakage. Therefore, a part of the leaked liquid is stored by the sink 311 on the sealing member 300, and the liquid storage tank 241 will not store all the leaked liquid, thereby greatly reducing the storage pressure of the liquid storage tank 241 on the leaked liquid, and further improving the anti-leakage capability of the atomizer 10.

[0048] See also Fig.10 and Fig.11 The present invention also provides an electronic atomization device 20, which includes a power supply 30 and the above-mentioned atomizer 10, and the atomizer 10 is detachably connected to the power supply 30. Since the atomizer 10 has a good anti-leakage ability, on the one hand, it can avoid the waste of liquid caused by leakage. On the other hand, it can prevent the leaked liquid from invading the inside of the power supply 30 and corroding the battery and electronic components, thereby improving the service life of the electronic atomization device 20.

[0049] 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.

[0050] 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.
