[0026] In view of the problem that the liquid storage bottle 2 of the electronic atomization device 100 in the related art is inverted, causing the whole liquid guide 6 to be easily in a supersaturated state, please refer to Figure 1 、 Figure 2The electronic atomization device 100 provided in the present application comprises an atomization module 101, which mainly comprises a liquid storage bottle 2, a heating core 3, a liquid outlet 5, a liquid guide 6 and a flow limiting piece 7. The liquid storage bottle 2 is provided with a liquid storage cavity 21 for storing an atomization substrate, and the liquid in the liquid storage cavity 21 can flow out of the liquid storage cavity 21 by gravity. The heating core 3 is used for heating and atomizing the atomization substrate. The liquid outlet 5 is detachably connected with the liquid storage bottle 2. When the liquid storage bottle 2 is connected with the liquid outlet 5, the liquid outlet 5 is in communication with the liquid storage cavity 21, and the atomization substrate can flow out of the liquid outlet 5 under the action of gravity. The liquid guide 6 is arranged between the liquid outlet 5 and the heating core 3, and is used for transmitting the atomization substrate flowing out of the liquid outlet 5 to the heating core 3. The flow limiting piece 7 is arranged between the liquid guide 6 and the liquid outlet 5, and the liquid guiding efficiency of the flow limiting piece 7 is less than that of the liquid guide 6, and is used for inhibiting the transmission of the atomization substrate.
[0027] It can be understood that the flow limiting piece 7 has a certain atomization substrate transmission capacity. On the atomization substrate transmission path between the liquid outlet 5 and the heating core 3, the flow limiting piece 7 is located at an upstream position of the liquid guide 6, and the atomization substrate flowing out of the liquid outlet 5 passes through the flow limiting piece 7 and the liquid guide 6 in sequence. On the one hand, the liquid guide 6 will not be directly soaked by the atomization substrate in the liquid storage cavity 21, and on the other hand, the transmission speed of the atomization substrate after passing through the flow limiting piece 7 will be weakened due to the fact that the liquid guiding efficiency of the flow limiting piece 7 is less than that of the liquid guide 6. Therefore, compared with the related art, the liquid guide 6 of the present application is not prone to over-saturation.
[0028] Moreover, the present application solves the problem of over-saturation of the liquid guide 6 by utilizing the characteristics of the material, without relying on external energy, such as without additional power supply, so it will not cause the draw number of the electronic atomization device 100 to become smaller.
[0029] Of course, the flow limiting piece 7 is not necessarily limited to being arranged between the liquid guide 6 and the liquid outlet 5, and the flow limiting piece 7 can also be arranged on the liquid guide 6, which can be applied to the embodiment in which there is no additional space for accommodating the flow limiting piece 7 between the liquid guide 6 and the liquid outlet 5. In this way, the over-saturation of the liquid guide 6 in the direction of transmission of the atomization substrate, which is located at a downstream position of the flow limiting piece 7, can be limited, thereby effectively preventing the electronic atomization device 100 from leaking liquid.
[0030] Continuing to see the structure of the electronic atomization device 100, the electronic atomization device has a proximal end 102 and a distal end 103 arranged opposite to the proximal end 102. The proximal end 102 is provided with an air outlet 4 in communication with the outside, and the air outlet 4 is in communication with the outside to output the atomized aerosol to the outside.
[0031] For the convenience of description, the proximal end 102 is taken as the top and the distal end 103 is taken as the bottom; for the structure in the electronic atomization device 100, the side close to the proximal end 102 is taken as the top / end / proximal end, and the side close to the distal end 103 is taken as the bottom / end / distal end.
[0032] As shown in Figure 2 , the liquid storage bottle 2 is replaceably arranged in the electronic atomization device 100 to facilitate the replenishment of the atomization substrate. In an embodiment, the bottle mouth of the liquid storage bottle 2 can be detachably mounted at the liquid outlet 5 by means of threaded connection, snap connection or interference fit, etc. Preferably, to avoid liquid leakage between the liquid storage bottle 2 and the liquid outlet 5, a sealing member can also be arranged between the bottle mouth of the liquid storage bottle 2 and the liquid outlet 5.
[0033] Of course, the atomization module 101 can also directly define the liquid storage cavity 21 with the inner wall of the shell 1, which is not limited here; the shell 1 here can be understood as the shell 1 that accommodates the heating core 3, the liquid guide 6 and the flow limiting member 7, etc. Secondly, the liquid outlet 5 can also be directly the bottle mouth of the liquid storage bottle 2, which is not limited here.
[0034] A part of the liquid guide 6 can be located at a position opposite to the liquid outlet 5, and the liquid guide 6 can be provided with a slot 611 at the position opposite to the liquid outlet 5; the flow limiting member 7 can be mounted in the slot 611, and the atomization substrate flowing out of the liquid outlet 5 can pass through the flow limiting member 7 and then be transmitted to the liquid guide 6. Understandably, since the flow limiting member 7 is arranged at the position opposite to the liquid outlet 5, the flow limiting member 7 can withstand the pressure of the atomization substrate flowing out of the liquid outlet 5, and the liquid pressure received by the liquid guide 6 downstream of the flow limiting member 7 can be greatly reduced, so that the probability of over-saturation of the liquid guide 6 can be reduced.
[0035] For example, referring to Figure 2 , the plane where the liquid outlet 5 is located is arranged perpendicular to the length direction L of the electronic atomization device 100, at this time, the liquid outlet 5 and the flow limiting member 7 are arranged opposite to each other in the length direction L of the electronic atomization device 100. Understandably, the liquid storage cavity 21 is located above the liquid outlet 5; when the plane where the liquid outlet 5 is located is arranged perpendicular to the length direction L of the electronic atomization device 100, the liquid pressure at the liquid outlet 5 will be relatively large due to the action of gravity.
[0036] Of course, the plane where the liquid outlet 5 is located can also be arranged parallel to the length direction L of the electronic atomization device 100, at this time, the liquid outlet 5 and the flow limiting member 7 are arranged opposite to each other in the width direction W of the electronic atomization device 100. Understandably, the change of the direction of the liquid outlet 5 makes the atomization substrate in the liquid storage cavity 21 not directly flow out of the liquid outlet 5 from top to bottom, and the wall at the upstream position of the liquid outlet 5 in the liquid flow direction will bear part of the liquid pressure, thereby weakening the liquid pressure at the liquid outlet 5.
[0037] Please continue to refer to Figure 3 and Figure 4 , the atomization module 101 can further include a first mounting frame 71 which is inserted into the insertion slot 611 of the liquid guide 6, and the flow limiting piece 7 is arranged in the first mounting frame 71 and in fluid communication with the liquid storage cavity 21 through the liquid outlet 5, and the first mounting frame 71 is further provided with a communication port 711, and the flow limiting piece 7 is in fluid communication with the liquid guide 6 through the communication port 711.
[0038] It can be understood that fluid communication means that the atomized substrate belonging to the fluid can be transmitted between different two components.
[0039] The first mounting frame 71 is used to provide a mounting basis for the flow limiting piece 7, and at the same time, it can also play a role in protecting the flow limiting piece 7. The first mounting frame 71 can be in a cylindrical shape, such as a circular cylindrical shape. The port of the first mounting frame 71 can be arranged opposite to the liquid outlet 5, and the atomized substrate flowing out of the liquid outlet 5 can flow into the flow limiting piece 7 through the port of the first mounting frame 71. Secondly, a plurality of communication ports 711 can be formed on the circumferential side wall of the first mounting frame 71, and the atomized substrate can pass through the communication ports 711 to reach the liquid guide 6. Optionally, the communication ports 711 are arranged along the circumference of the first mounting frame 71 to facilitate the flow of the atomized substrate to the liquid guide 6.
[0040] In addition, as shown in Figure 3 or Figure 4 , a protection structure 72 can be arranged between the first mounting frame 71 and the flow limiting piece 7, which is used to avoid direct contact between the flow limiting piece 7 and the first mounting frame 71, and reduce the probability of damage to the flow limiting piece 7. For example, a plurality of layers of non-woven fabric can be wound around the outer periphery of the flow limiting piece 7. On the one hand, the plurality of layers of non-woven fabric can serve as the protection structure 72, and on the other hand, the non-woven fabric will not hinder the transmission of the atomized substrate between the flow limiting piece 7 and the liquid guide 6.
[0041] A sealing ring 73 can be arranged between the first mounting frame 71 and the liquid outlet 5 to avoid leakage of the atomized substrate from between the first mounting frame 71 and the liquid outlet 5.
[0042] As shown in Figure 3 , the flow limiting piece 7 can be in a cylindrical shape. For reference Figure 2 , the inner diameter of the flow limiting piece 7 can be smaller than the hole diameter of the liquid outlet 5, and the outer diameter of the flow limiting piece 7 is greater than the hole diameter of the liquid outlet 5, so that the end face of the flow limiting piece 7 can abut against the edge position of the liquid outlet 5; secondly, the midpoint of the liquid outlet 5 can be located on the central axis of the flow limiting piece 7.
[0043] It can be understood that, since the flow limiting member 7 is in a cylindrical shape and coaxially arranged with the liquid outlet 5, when the atomization substrate flows into the first mounting frame 71, the atomization substrate can flow into the inner periphery of the flow limiting member 7 by inertia, and then flow from the inner periphery of the flow limiting member 7 to the liquid guide 6 through the flow passage. In this way, the contact area between the atomization substrate and the flow limiting member 7 can be increased, and the overall atomization substrate transmission efficiency of the atomization module 101 during operation can be properly adjusted, that is, the balance between liquid supply, liquid guide and liquid consumption (atomization substrate consumption) can be controlled, so that the overall atomization substrate transmission efficiency is not too low due to the arrangement of the flow limiting member 7, and the dry burning and paste core of the heating core 3 are avoided. Secondly, since the end face of the flow limiting member 7 can abut the edge position of the liquid outlet 5, on the one hand, the atomization substrate can flow from the end face of the flow limiting member 7, which is beneficial to increase the contact area between the atomization substrate and the flow limiting member 7, and on the other hand, the smaller the aperture of the flow limiting member 7, the larger the volume, and the better the liquid pressure resistance of the flow limiting member 7.
[0044] The liquid guide 6 can be a fiber structure, and the flow limiting member 7 can be a ceramic structure. In an embodiment, the liquid guide 6 can be a cotton structure.
[0045] It can be understood that, in the related art, the liquid guide 6 generally adopts a fiber structure, but due to the cavity and swelling of the fiber structure, the physical barrier property of the fiber structure is easily affected by time / temperature / air pressure. In the case of long-term soaking of the liquid guide 6, high-temperature environment or certain altitude environment, the physical barrier property of the fiber structure is easily lost, and without the barrier effect of the fiber structure, the atomization substrate in the liquid storage cavity 21 will flow out as much as possible, resulting in liquid leakage of the electronic atomization device 100.
[0046] However, the design of the flow limiting member 7 in the present application can avoid the failure of the fiber structure due to environmental / time factors. At the same time, since the ceramic has a certain liquid guiding ability, when the flow limiting member 7 is made of ceramic material, it will not excessively affect the overall atomization substrate transmission efficiency of the atomization module 101 during operation, so the dry burning and paste core of the heating core 3 due to the arrangement of the flow limiting member 7 will not occur. Moreover, compared with the fiber, the ceramic material also has good pressure stability, and can withstand the liquid pressure.
[0047] Continuing to refer to Figure 5 , the liquid guide 6 can include a first liquid guide part 61 and a second liquid guide part 62 connected with the first liquid guide part 61; the liquid outlet 5 and the second liquid guide part 62 are arranged at intervals in the width direction W of the electronic atomization device 100, and at least part of the structure of the first liquid guide part 61 is located between the liquid outlet 5 and the second liquid guide part 62; the heating core 3 is arranged in the second liquid guide part 62. The first mounting frame 71 is inserted into the first liquid guide.
[0048] Understandably, the second liquid guide part 62 is located downstream of the first liquid guide part 61 in the transmission direction of the atomized substrate along the atomized substrate, and the atomized substrate coming out of the liquid outlet 5 needs to pass through the transmission of the first liquid guide part 61 to reach the second liquid guide part 62.
[0049] The first liquid guide part 61 and the second liquid guide part 62 can be integrally connected, or connected by snap connection, interference fit, etc., which is not limited here.
[0050] As shown in Figure 5 The second liquid guide part 62 can be a strip-shaped structure, and its length direction is parallel to the length direction L of the electronic atomization device 100; in the length direction L of the electronic atomization device 100, the heating core 3 can be located between the liquid outlet 5 and the gas outlet 4.
[0051] Understandably, under the multiple actions of the suction pressure, the liquid pressure and the capillary force, the atomized substrate is transmitted to the heating core 3 at a relatively fast speed, and if the consumption of the heating core 3 cannot keep up with the transmission amount of the atomized substrate, the atomized substrate will seep from the heating core 3, thereby causing the problem of liquid leakage. By arranging the heating core 3 between the liquid outlet 5 and the gas outlet 4 in the length direction L of the electronic atomization device 100, when the atomized substrate is transmitted to the second liquid guide part 62, it needs to overcome the gravity to be transmitted to the heating core 3. By such arrangement, the transmission speed of the atomized substrate to the heating core 3 can be prevented from being too fast, thereby preventing the problem of the atomized substrate seeping from the heating core 3.
[0052] The second liquid guide part 62 is provided with a hollow channel 621; one end of the hollow channel 621 is in communication with the gas outlet 4, and the other end is in communication with the outside.
[0053] The heating core 3 is arranged in the hollow channel 621, and the distance H between the heating core 3 and the bottom end of the hollow channel 621 is between 13.5mm-18.5mm.
[0054] Understandably, by limiting the distance between the heating core 3 and the bottom end of the hollow channel 621, on the one hand, it can ensure that the atomized substrate needs to overcome a certain gravity to reach the heating core 3, thereby preventing the atomized substrate from being transmitted to the heating core 3 at too fast a speed, and on the other hand, it can also ensure that the transmission amount of the atomized substrate can keep up with the consumption amount of the heating core 3, thereby preventing the heating core 3 from being dry-burned.
[0055] The hollow passage 621 of the second liquid guiding part 62 can also be inserted with a second mounting rack 622 in a cylindrical shape, and the circumferential sidewall of the second mounting rack 622 is provided with an opening 623; the heating core 3 is arranged at the position of the opening 623. The second mounting rack 622 can play a role in protecting the second liquid guiding part 62, and can also avoid the atomized substrate flowing out from the positions other than the position of the opening 623 of the second liquid guiding part 62.
[0056] The first liquid guiding part 61 can be in a strip-shaped structure, and the end of the first liquid guiding part 61 away from the liquid outlet 5 is closer to the distal end 103 than the other end.
[0057] It can be understood that, in order to control the balance among liquid supply, liquid guiding and liquid consumption, the first liquid guiding part 61 can be inclined from the upstream end to the downstream end, which is beneficial to improve the transmission efficiency of the first liquid guiding part 61 and prevent the overall atomized substrate transmission efficiency from being excessively slowed down due to the arrangement of the flow limiting part 7. At the same time, it can also avoid excessive accumulation of atomized substrate at the first liquid guiding part 61, thereby reducing the probability of over-saturation of the first liquid guiding part 61.
[0058] In an embodiment, the first liquid guiding part 61 can be arranged in a way that the end of the first liquid guiding part 61 away from the liquid outlet 5 is closer to the distal end 103 than the other end. Figure 3 The bracket 8 arranged on the side of the first liquid guiding part 61 close to the distal end 103 of the atomization module 101 is provided with a supporting surface 81 for supporting the first liquid guiding part 61. The supporting surface 81 is at least partially in the form of an inclined surface at an angle θ with the width direction W of the electronic atomization device, so that the end of the first liquid guiding part 61 away from the liquid outlet 5 is closer to the distal end 103 than the other end. In addition, the thickness of the end of the first liquid guiding part 61 close to the liquid outlet 5 can be smaller than the thickness of the other end, and the thickness direction refers to the length of the first liquid guiding part 61 in the length direction L of the electronic atomization device 100, so that the bottom surface of the first liquid guiding part 61 is at least partially in a complementary inclined surface relationship with the supporting surface 81, so that the top of the first liquid guiding part 61 can remain horizontal, which is beneficial to the flatness of other structures in the electronic atomization device 100.
[0059] Of course, in addition to the inclined surface arrangement, two spaced-apart clamping positions can also be arranged on the inner wall surface of the shell 1. The two clamping positions are high and low, and the two ends of the first liquid guiding part 61 can be respectively inserted into the corresponding clamping positions to be relatively fixedly mounted in the shell 1. After installation, the end of the first liquid guiding part 61 away from the liquid outlet 5 can be closer to the distal end 103 than the other end.
[0060] Continuing to refer to the first liquid guiding part 61, Figure 2 The bracket 8 can also have a through hole 82 that is in communication with the hollow passage 621 of the second liquid guiding part 62. The through hole 82 is in communication with the outside, and air from the outside can pass through the through hole 82 to enter the hollow passage 621 and carry the atomized atomized substrate to the air outlet 4.
[0061] The liquid suction structure 9 can be a liquid suction cotton made of cotton material.
[0062] In addition, the electronic atomization device 100 further comprises a power module 104, which is configured to generate working power and provide the working power for the atomization module 101 through electrical connection.
[0063] For example, the heating core 3 of the atomization module 101 generates heat based on the principle of resistance heating, and the power module 104 can be electrically connected with the heating core 3 and provide power for the heating core 3.
[0064] It can be understood that the above embodiments only express the preferred embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present application; it should be pointed out that for ordinary skilled in the art, the above technical features can be freely combined without departing from the concept of the present application, and some deformations and improvements can be made, which belong to the protection scope of the present application; therefore, any equivalent transformation and modification within the scope of the claims of the present application shall belong to the scope of the claims of the present application.
