Atomizer and Electronic Atomization Device

Abstract

The present invention relates to an atomizer and an electronic atomization device, comprising a shell, a gas-liquid separator and an atomization component. The interior of the shell is divided into an oil storage chamber and an atomization chamber by the gas-liquid separator. The atomization component is arranged in the atomization chamber. The gas-liquid separator is provided with an oil guide hole. The atomization component is connected with a capillary oil locking structure through the oil guide hole. The capillary oil locking structure is arranged in the oil storage chamber near one end of the suction nozzle. When the electronic atomization device is not in use, the atomization component will not be in direct contact with the smoke oil for a long time, so that the smoke oil of the atomization component will not be too saturated due to excessive oil supply, causing a small amount of smoke oil to leak out of the oil storage chamber, affecting the main unit of the electronic atomization device or affecting the suction taste. When the electronic atomization device is used, no matter how much or how little smoke oil there is in the oil storage chamber, the capillary oil locking structure can absorb more smoke oil through its capillary action, thereby ensuring that the atomization component connected with the capillary oil locking structure through the oil guide hole can absorb more smoke oil, and can avoid the situation of untimely oil guide and insufficient oil supply when the atomization component atomizes the smoke oil and causes dry burning.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0027] Please refer to Figure 1 , which is a schematic structural diagram of the atomizer 10 in an embodiment.

[0028] Please refer to Figure 2 、 Figure 3 , the atomizer 10 is a smoke generating device of an electronic atomization device. The atomizer 10 includes a housing 12, a gas-liquid separation member 14, and an atomization assembly 16. The housing 12 includes opposite first and second ends. The gas-liquid separation member 14 is inserted into the housing 12, and the gas-liquid separation member 14 seals the first end and the second end of the housing 12, that is, a closed cavity is formed inside the housing 12. The cavity is divided into an oil storage cavity 122 and an atomization cavity 124 by the gas-liquid separation member 14. The atomization assembly 16 is disposed in the atomization cavity 124. E-liquid is stored in the oil storage cavity 122. The gas-liquid separation member 14 is provided with an oil guiding hole 141, and the atomization assembly 16 is communicated with the oil storage cavity 122 through the oil guiding hole 141 for oil guiding.

[0029] Specifically, please refer to Figure 2 , the gas-liquid separation member 14 includes a mouthpiece 142 extending from the first end of the housing 12 and a capillary oil locking structure 144 disposed in the oil storage cavity 122. The capillary oil locking structure 144 is close to the first end of the housing 12, that is, the capillary oil locking structure 144 is disposed at the upper part of the atomizer 10, and the capillary oil locking structure 144 is communicated with the oil guiding hole 141. When the electronic atomization device is not in use, since the capillary oil locking structure 144 is disposed at the upper part of the atomizer 10, when the e-liquid in the oil storage cavity 122 is not full, the capillary oil locking structure 144 will not be immersed in the e-liquid, so that the atomization assembly 16 will not be in direct contact with the e-liquid through the oil guiding hole 141 for a long time, and thus it will not cause the atomization assembly 16 to be too saturated with e-liquid due to excessive oil supply, resulting in a small amount of e-liquid leaking out of the oil storage cavity 122 and flowing to the main body of the electronic atomization device, thereby corroding the electronic components in the main body of the electronic atomization device, or the e-liquid leaking out during suction being sucked into the user's mouth, affecting the suction taste. When the electronic atomization device is in use, the user will hold the electronic atomization device with a certain inclination. Therefore, regardless of the amount of e-liquid in the oil storage cavity 122, the capillary oil locking structure 144 can adsorb more e-liquid through its capillary action, so as to ensure that the atomization assembly 16 communicated with the capillary oil locking structure 144 through the oil guiding hole 141 can absorb more e-liquid. When the atomization assembly 16 atomizes the e-liquid to form smoke, the e-liquid adsorbed by the capillary oil locking structure 144 can prevent the atomization assembly 16 from running out of oil supply in time and insufficient oil supply, resulting in dry burning.

[0030] Further, the capillary oil-locking structure 144 is provided with at least two fins 1442, and the at least two fins 1442 are spaced apart, and a capillary groove 1444 is formed between adjacent fins 1442; since both sides of the capillary groove 1444 are respectively communicated with the oil storage cavity 122 and the oil guiding hole 141, it is necessary to set the number of fins 1442 and the spacing between the fins 1442 according to the atomization speed of the atomization component 16 for the e-liquid, the size and shape of the oil guiding hole 141, and the oil absorption capacity of different spacings between the fins 1442 of the capillary oil-locking structure 144, so as to ensure that the capillary oil-locking structure 144 can lock an appropriate amount of e-liquid for the atomization component 16 to absorb, and it will not cause the atomization component 16 to absorb excessive oil due to too much e-liquid locked by the capillary oil-locking structure 144.

[0031] Please refer to Figure 2 、 Figure 3 In this embodiment, the gas-liquid separation member 14 further includes a first sealing end cover 145, a second sealing end cover 146 and a gas-liquid separation tube 148. The two ends of the gas-liquid separation tube 148 are respectively connected to the first sealing end cover 145 and the second sealing end cover 146, that is, this part of the gas-liquid separation member 14 is in an "I" shape. The housing 12 is arranged on the outer periphery of the "I", and the first sealing end cover 145 covers the first end of the housing 12, and the second sealing end cover 146 covers the second end of the housing 12, sealing the two ends of the housing 12, so that a cavity capable of accommodating liquid or gas is formed inside the housing 12. The gas-liquid separation tube 148 can further separate the cavity inside the housing 12. Since the gas-liquid separation tube 148 itself is a hollow pipe structure, the cavity inside the housing 12 can be separated into two parts: the internal space of the gas-liquid separation tube 148 and the external space of the pipe. At the same time, since through holes communicating with the outside are opened at both ends of the gas-liquid separation tube 148, the air required for atomizing the e-liquid can be provided. Therefore, the internal space of the gas-liquid separation tube 148 and the external space of the pipe are respectively the atomizer 10 and the oil storage cavity 122, that is, the inner wall cavity formed after the housing 12 is sealed by the first sealing end cover 145 and the second sealing end cover 146 is separated into the oil storage cavity 122 and the atomization cavity 124 by the gas-liquid separation tube 148, and the oil guiding hole 141 is arranged on the wall surface of the gas-liquid separation tube 148, so that the e-liquid in the oil storage cavity 122 can be led out to the atomization component 16 in the atomizer 10 through the oil guiding hole 141.

[0032] Of course, a smooth arc can also be provided between the first sealing end cover 145 and the mouthpiece 142 to make the appearance smooth and beautiful.

[0033] The suction nozzle 142 of the gas-liquid separation element 14 is arranged at the upper part of the "工" character, forming a structure similar to the "土" character, and the suction nozzle 142 is connected to the gas-liquid separation tube 148. Furthermore, the suction nozzle 142 can be integrally formed with the gas-liquid separation tube 148, with a simple structure, and convenient and simple production and installation. The suction nozzle 142 and the gas-liquid separation tube 148 can also be detachably arranged, which can be convenient for cleaning the suction nozzle 142, or convenient for replacing the suction nozzle 142.

[0034] Of course, the gas-liquid separator 14 can be made of silicone as a whole, and the shell 12 can be made of tempered glass. The gas-liquid separator 14 and the shell 12 are detachable. When the shell 12 is damaged, the damaged shell 12 can be replaced with a new shell 12; when the gas-liquid separator 14 or the atomization component 16 therein is damaged, the shell 12 can be disassembled and replaced with a new gas-liquid separator 14 or atomization component 16; when the oil storage cavity 122 is dirty and needs to be cleaned after long-term use, the shell 12 can be disassembled and cleaned; when the gas-liquid separator 14 and the shell 12 are installed, some glue can be applied at the contact between the silicone component and the tempered glass to ensure that the sealing performance between the gas-liquid separator 14 and the shell 12 is good.

[0035] Specifically, the housing 12 may be a hollow columnar structure, the fin 1442 is arranged in parallel with the first sealing end cover 145, and a capillary groove 1444 is formed between the fin 1442 and the first sealing end cover 145. When the electronic atomization device is used, the electronic atomization device is tilted, so that the smoke oil is close to the first sealing end cover 145, and the capillary groove 1444 is formed between the fin 1442 and the first sealing end cover 145, so that more smoke oil can be sucked into the capillary groove 1444, so that the oil supply is more sufficient.

[0036] To ensure good capillary phenomenon and good conduction of smoke oil, the width of the capillary groove 1444 formed by the gap between the fins 1442 is preferably 0.5 mm to 1.5 mm.

[0037] To prevent the fin 1442 from being too thick and taking up too much space, resulting in insufficient oil absorption due to the capillary phenomenon and blocking more oil inlet positions of the oil guide hole 141; and to prevent the fin 1442 from being too thin and deforming after the capillary groove 1444 absorbs the smoke oil, thereby affecting the capillary phenomenon, the thickness of the fin 1442 is preferably 0.6 mm to 1.2 mm.

[0038] The fin 1442 is set at an angle to the housing 12, one end of the fin 1442 is fixed to the gas-liquid separation tube 148, and the distance between the other end of the fin 1442 and the housing 12 is 0.5mm to 2mm. That is, a gap of 0.5mm to 2mm is set between the wing tip of the fin 1442 and the housing 12 to ensure that the smoke oil can flow to the end where the first sealing end cover 145 is located when the atomizer 10 is tilted, so that each capillary groove 1444 can absorb the smoke oil. Here, the fin 1442 is set at an angle to the housing 12, preferably, the fin 1442 is set at 90 degrees to the housing 12.

[0039] See also Figure 3 In this embodiment, the suction nozzle 142, the first sealing end cover 145, the second sealing end cover 146 and the gas-liquid separation tube 148 are all made of silicone. On the one hand, the silicone material has a good feel and taste. On the other hand, the silicone material has a certain degree of softness, which is convenient to operate when assembling and disassembling with the shell 12. The silicone itself can act as a seal, which can reduce the number of parts of the atomizer 10. The second sealing end cover 146 is provided with an oil injection cutout 1462, which is connected to the oil storage chamber 122 and can be opened and closed. Since the second sealing end cover 146 needs to have a certain thickness so as not to be deformed when the oil storage chamber 122 is filled with tobacco oil, and the silicone material of the second sealing end cover 146 itself has a certain deformation ability, on the one hand, tobacco oil can be filled into the oil storage chamber 122 through the oil injection cutout 1462, and on the other hand, when the injection component for filling tobacco oil is pulled out of the oil injection cutout 1462, the oil injection cutout 1462 is quickly restored due to the deformation ability of the silicone itself, and since the second sealing end cover 146 has a certain thickness, the extrusion pressure of the oil injection cutout 1462 is relatively large, and the tobacco oil cannot leak out from the oil injection cutout 1462, and there is no need to install other anti-oil leakage components, the structure is simple, and it is conducive to saving space.

[0040] See also Figure 2 In this embodiment, the atomization assembly 16 includes an oil guide element 162 and a heating element 164. The heating element 164 is a hollow tubular structure. The oil guide element 162 is wrapped around the outside of the heating element 164, and the oil guide element 162 fits the oil guide hole 141; that is, the oil guide element 162 absorbs the smoke oil in the oil storage cavity 122 for heating and atomization by the heating element 164, and the smoke oil is evenly attached to all parts of the heating element 164 through the hollow part, so as to avoid the situation where a certain part of the heating element 164 does not contact the smoke oil or the oil supply is insufficient, resulting in dry burning; and the hollow tubular shape of the heating element 164 can provide airflow circulation, provide the air required for atomizing the smoke oil, and bring the smoke formed after atomization and the air out to the suction nozzle 142 for use. Preferably, the oil guide element 162 can be an oil guide cotton, and the heating element 164 can be a heating net, a heating wire, etc.

[0041] See also Figure 3, the atomization component 16 can directly contact the oil guiding of the gas-liquid separation tube 148. Preferably, an auxiliary tube 18 can be provided between the atomization component 16 and the gas-liquid separation tube 148. The auxiliary tube 18 is provided with the same through holes corresponding to the positions where the oil guiding holes 141 or other through holes are provided in the gas-liquid separation tube 148, and the auxiliary tube 18 is a rigid pipe fitting. When assembling the atomizer 10, the atomization component 16 can be first installed at a preset position, and then the atomization component 16 and the auxiliary tube 18 are inserted and installed together in the atomization cavity 124, so that the inner wall surface and the outer wall surface of the auxiliary tube 18 are respectively attached to the inner wall of the atomization component 16 and the gas-liquid separation tube 148, and the oil storage cavity 122 can communicate with the atomization component 16 through the oil guiding hole 141.

[0042] An atomization seat is provided at one end of the atomization cavity 124 where the second sealing end cover 146 is located. On the one hand, it can position electrodes, heating elements 164, etc. On the other hand, air inlet holes of appropriate sizes can be provided on the atomization seat according to the airtightness requirements of the atomizer 10 to ensure sufficient air for atomizing the e-liquid, and at the same time, it will not cause dry hits due to too much air intake or poor suction due to too little air intake.

[0043] Further, please refer to Figure 2 , a liquid storage tank 1242 is further provided in the atomization cavity 124. The liquid storage tank 1242 is provided between the atomization component 16 and the second sealing end cover 146, and the liquid storage tank 1242 is arranged along the inner wall of the gas-liquid separation tube 148. That is, a hollow tubular body is provided in the atomizer 10 between the atomization component 16 and the atomization seat. The hollow tubular body includes a first end close to the atomization seat and a second end far from the atomization seat. A shoulder is provided on the outer wall of the first end, and there is a certain distance between the outer wall of the second end and the inner wall of the gas-liquid separation tube 148. The shoulder and the distance cooperate to form the bottom and wall of the liquid storage tank 1242, so that the condensate that may be formed during the use of the atomizer 10 is stored in the liquid storage tank 1242. On the one hand, the condensate can be absorbed by the oil guiding element 162, so that it will not be inhaled into the mouth by the user when using the electronic atomization device, affecting the suction taste and experience. On the other hand, the condensate absorbed by the oil guiding element 162 can be atomized again when the atomization component 16 works, reducing the condensate in the atomizer 10.

The main body 20 is provided with a first magnetic attraction element, and the atomizer 10 is provided with a second magnetic attraction element. The main body 20 and the atomizer 10 are magnetically connected through the first magnetic attraction element and the second magnetic attraction element. The specific structure of the atomizer 10 refers to the above embodiments. Since this electronic atomization device adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0045] Of course, the atomizer 10 and the main unit 20 can also be connected by plugging and unplugging through a buckle or the like.

[0046] Specifically, please refer to Figure 5 and Figure 6 , the main unit 20 is the control center of the electronic atomization device, including a housing, a battery and a control main board. The battery and the control main board are electrically connected and are both arranged inside the housing. The control main board is provided with a pneumatic switch, and the pneumatic switch controls the on-off power between the main unit 20 and the atomizer 10. When the electronic atomization device needs to be used, inhaling at the mouthpiece 142 activates the pneumatic switch, so that the control main board, the battery and the atomization assembly 16 are powered on, so that the heating element 164 is powered on to heat the e-liquid on the oil guiding element 162, generating smoke for the user to inhale. The housing is also provided with a through hole communicating with the outside for the atomizer 10 to intake air.

[0047] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.
