And the heating component heats the oil adsorbed from the oil storage cavity 12 under the driving action of the electric energy of the power supply device to generate smoke, and the generated smoke flows out of the outside through an airflow channel arranged in the atomizing device 1000 for a user to suck.

Referring to fig. 1 or 9, in the embodiment of the present invention, the atomizing device 1000 includes a base 100 and an atomizing core 200, the base 100 includes a housing 10 with an opening 11 and a sealing seat 30 made of a flexible material, the sealing seat 30 is used to seal the opening 11 and is enclosed with an inner wall of the housing 10 to form an oil storage chamber 12. The seal seat 30 is provided with a mounting cavity 31 for mounting the atomizing core 200, the atomizing core 200 includes a first portion 210 and a second portion 220, and an oil guide hole 230 communicating with an atomizing cavity 240 inside the atomizing core 200 is formed in an outer wall of the atomizing core 200 between the first portion 210 and the second portion 220. When the atomizing core member 200 is preassembled in the first position of the base body 100, the first portion 210 is inserted into the mounting cavity 31, the second portion 220 protrudes out of the base body 100, and the oil guide hole 230 between the first portion 210 and the second portion 220 is covered by the seal seat 30 of the base body 100 and is elastically blocked. At this time, the oil storage chamber 12 is a closed chamber, and the smoke stored inside cannot flow into the atomizing core 200 through the oil guide hole 230, so that the smoke cannot leak into the oil storage chamber 12 through the oil guide hole 230 and then leak out to the outside through the air flow passage during transportation.

Further, as shown in fig. 3, 10 or 11, when the second portion 220 is pressed by an external force so that the atomizing core 200 moves toward the inside of the base 100 to a second position of the base 100, the oil guide hole 230 is communicated with the oil storage chamber 12, so that the oil stored in the oil storage chamber 12 permeates into the atomizing core 200 through the oil guide hole 230, and the final assembly is completed, so that the atomizing core can be normally used.

It should be understood that, in practical applications, the base body 100 is not limited to the above-mentioned manner of installing the elastic sealing seat 30 on the housing 10, so that the oil guide hole 230 is elastically covered and sealed by the sealing seat 30 when the atomizing core 200 is pre-installed at the first position. For example, in other embodiments of the present invention, the sealing seat 30 and the housing 10 are both made of hard material, and a sheath made of flexible material is sleeved on the atomizing core 200 at the position where the oil guide hole 230 is provided, so that when the atomizing core 200 is inserted to the first position, the sheath elastically abuts against the inner cavity wall of the mounting cavity 31; or, when atomizing core 200 inserted to the first position, atomizing core 200 surface and the installation cavity 31 inner chamber wall interference butt that seal receptacle 30 was equipped with realized hiding inclosed mode and all belong to within the scope of protection of the utility model.

For example, the inner wall space on the left side of the housing 10 is a reservoir 12, the space on the right side of the housing 10 and the space opened on the seal holder 30 form a mounting chamber 31 as a whole, and when the seal holder 30 is mounted on the housing 10, the opening 11 is closed, and the reservoir 12 and a part of the mounting chamber 31 are two independent chambers in the housing 10. Further, the partition 17 is opened with an oil passing hole 171. When the atomizing core 200 is preassembled in the first position, a part of the first portion 210 of the atomizing core 200 passes through the seal seat 30 and is accommodated in the mounting cavity 31 of the housing 10, and is tightly attached to the partition 17, so as to prevent oil in the oil storage chamber 12 from leaking out through the oil passing hole 171 during transportation. After the user purchases the oil storage cavity, the user only needs to apply pressure to the second portion 220 of the atomizing core 200 to press the atomizing core 200 into the mounting cavity 31, so that the oil guide hole 230 and the oil passing hole 171 formed in the atomizing core 200 are in direct contact with each other, and the oil stored in the oil storage cavity 12 can flow into the atomizing core 200 through the oil passing hole 171.

Of course, it is understood that, in the embodiment of the present invention, the installation cavity 31 and the oil storage cavity 12 are not limited to the left and right separation setting in the above embodiment, for example, the installation cavity is simply replaced by the right and left separation setting or the up and down separation setting, the up and down separation or the dislocation separation, etc., all belong to the protection scope of the present invention.

Further, in order to ensure that the atomizing core 200 is mounted on the second position of the base body 100, the oil guide hole 230 and the oil passing hole 171 are aligned. In the first embodiment of the present invention, the cross-section of the first portion 210 of the atomizing core 200 is polygonal. The oil guide holes 230 are formed in the surfaces of the atomizing core 200, so that the oil guide holes 230 are formed in the surfaces facing the partition 17 when the atomizing core 200 is pre-installed at the first position.

It is understood that, in practical applications, the above-mentioned way of using the polygonal cross section of the first portion 210 of the atomizing core 200 is not limited, and for example, a positioning member may be provided to pre-mount the atomizing core 200 on the base 100 only in a specific direction, so as to ensure that the oil guide hole 230 and the oil passing hole 171 are aligned with each other when the atomizing core 200 is mounted on the base 100 at the second position.

Further, as shown in fig. 10, in this embodiment, in order to prevent the oil in the oil storage chamber 12 from remaining in other positions of the base 100, when the oil guide hole 230 is communicated with the oil passing hole 171, the oil in the oil storage chamber 12 flows to the oil guide hole 230 only through the oil passing hole 171. The utility model discloses an embodiment, the area of oil guide hole 230 opening 11 is greater than the area of oil passing hole 171 opening 11, so that oil guide hole 230 with when oil passing hole 171 is just to the intercommunication, atomizing core 200 is equipped with the surface shroud of oil guide hole 230 the outer fringe of oil passing hole 171, and then effectively ensure oil guide hole 230 with when oil passing hole 171 communicates, the fluid of oil storage chamber 12 only passes through oil passing hole 171 flows to oil guide hole 230.

Further, it is understood that, in practical application, the mounting chamber 31 and the oil storage chamber 12 are not limited to the above embodiments, but may be two separate chambers. For example, as shown in fig. 1 or fig. 3, in the second embodiment of the present invention:

seal receptacle 30 just has seted up storage oil chamber 12 installation cavity 31, just installation cavity 31 with storage oil chamber 12 direct intercommunication. The shell 10 is further provided with a hollow air duct 15, one end of the air duct 15 is inserted into the oil storage cavity 12, and the other end of the air duct is communicated with the outside. The first part 210 of the atomizing core piece 200 is convexly provided with a hollow connecting pipe 2101, when the atomizing core piece 200 is pre-installed at a first position, the first part 210 of the atomizing core piece 200 is inserted along the installation cavity 31 arranged on the sealing seat 30, and one end of the connecting pipe 2101 far away from the first part 210 is pre-inserted into the air duct 15, so that the atomizing cavity 240 inside the atomizing core piece 200 is communicated with the air duct 15. At this time, the oil guide hole 230 provided in the atomizing core 200 is covered and sealed by the seal holder 30. When a user applies a pressing force to the second portion 220 of the atomizing core 200 to push the atomizing core 200 to be further inserted into the base body 100 to a second position, the oil guide hole 230 formed in the surface of the atomizing core 200 is exposed to the inside of the oil storage chamber 12. Further, the oil in the oil chamber 12 can flow into the atomizing chamber 240 in the atomizing core 200 through the oil guiding hole 230 for atomizing the heat generating component to generate smoke. And the atomizing core 200 is inserted into the oil storage chamber 12, so that the oil guide holes 230 are directly exposed in the oil storage chamber 12, thereby facilitating the penetration of oil, and a plurality of oil guide holes 230 can be formed on the surface of the atomizing core 200, further improving the penetration rate, and ensuring the supply of oil during atomization.

Specifically, as shown in fig. 3, in this embodiment, the distance from the oil guide hole 230 to the second portion 220 is slightly larger than the thickness of the seal in the installation cavity 31, and the installation cavity 31 is formed in the bottom of the oil storage cavity 12. Therefore, when the atomizing core 200 is inserted into the oil storage chamber 12 along the mounting chamber 31 and is inserted to the first position, the oil guide hole 230 is covered and sealed by the seal holder 30, and when the atomizing core is further inserted to the second position, the oil guide hole 230 is just completely exposed from the seal holder 30 to the oil storage chamber 12 and is located at the bottom of the oil storage chamber 12. Therefore, the oil penetrates into the atomization chamber 240 through the oil guide hole 230 by gravity. And the oil guide hole 230 is located at the bottom of the oil storage chamber 12, which effectively prevents the oil guide hole 230 from being arranged at a higher position and prevents the oil at the bottom of the oil storage chamber 12 from remaining in the oil storage chamber 12.

Further, as shown in fig. 1, fig. 3 or fig. 4, in this embodiment, a sealing ring 250 made of a flexible material, such as a sealing ring 250 made of elastic silica gel, elastic plastic or elastic resin, is further disposed between the connecting tube 2101 and the air guide tube 15, an inner annular surface of the sealing ring 250 is sleeved on an outer surface of the mouthpiece, and an outer annular surface of the sealing ring 250 elastically abuts against an inner wall of the air guide tube 15, so that the air guide tube 15 and the connecting tube 2101 are hermetically connected to prevent oil from leaking therebetween.

Further, as shown in fig. 4, in this embodiment, the sealing ring 250 is pre-installed in the air guiding tube 15, and the opening 11 of the sealing ring 250 facing one end of the installation cavity 31 is gradually enlarged to form an inclined surface with guiding function, or the outer edge of the end of the connecting tube 2101 is provided with a wedge-shaped guiding surface to prevent the connecting tube 2101 from being misaligned and abutted when inserted.

It will be appreciated that in practice, the sealing ring 250 is not limited to being pre-assembled to the airway tube 15, and one end of the sealing ring is tapered. For example, in other embodiments of the present invention, the sealing ring 250 may be pre-sleeved on the outer peripheral surface of the connecting pipe 2101, and the gas guiding tube 15 is disposed in a diverging manner toward the end of the installation cavity 31, so that the insertion manner is also within the protection scope of the present invention.

Further, as shown in fig. 3 or fig. 4, in this embodiment, a support ring 151 is further protruded from the inner wall of the airway tube 15, so that when the user pre-installs the sealing ring 250 in the airway tube 15, the support ring 151 supports an end of the sealing ring 250 away from the installation cavity 31. Meanwhile, the phenomenon that the sealing ring 250 is excessively inserted into the air duct 15 due to large stress is prevented.

Further, as shown in fig. 1, 3 and 4, in this embodiment, a cross-sectional area surrounded by the inner annular surface of the sealing ring 250 is larger than a cross-sectional area surrounded by the inner annular surface of the supporting ring 151, so that the phenomenon that the inner annular surface of the supporting ring 151 is covered by the offset of the sealing ring 250, which causes a small airflow, is effectively prevented.

Further, as shown in fig. 4, in this embodiment, at least one sealing rib 2501 is further protruded from an inner circumferential surface of the sealing ring 250, and when the connection pipe 2101 is inserted into the sealing ring 250, a surface of the sealing rib 2501 is held on an outer circumferential surface of the connection pipe 2101.

Further, as shown in fig. 1, fig. 3, or fig. 4, in this embodiment, a limiting member 2102 is further protruded from an outer periphery of the connecting tube 2101, when the atomizing core 200 is located at the first position, a certain distance is provided between the limiting member 2102 and the end surface of the air duct 15, and when the atomizing core 200 is forced to move to the second position, the limiting member 2102 and the end surface of the air duct 15 are spaced or in contact and abutted, so as to effectively prevent the user from exerting too much force to press and deform the seal seat 30, which results in a gap between the seal seat 30 and the housing 10, and oil leakage.

It will be appreciated that, in practice, the retaining member 2102 is not limited to the above-described embodiment, and is limited by abutting against the end face of the airway tube 15 to prevent the user from exerting too much force. For example, as shown in fig. 4, in other embodiments of the present invention, the thickness of the sealing ring 250 may be set to be thicker, so that when the sealing ring is preassembled in the air duct 15, one end of the sealing ring is elastically abutted against the supporting ring 151, and the other end of the sealing ring protrudes out of the air duct 15 and is accommodated in the oil storage cavity 12, when the limiting member 2102 moves along with the atomizing core 200 to contact with the sealing ring 250, the manner of limiting the abutment or the manner of limiting the abutment when the limiting member 2102 moves along with the atomizing core 200 to contact with the supporting bone is provided in the oil storage cavity 12, and the manner of limiting the abutment when the limiting member 2102 moves along with the atomizing core 200 to contact with.

Specifically, as shown in fig. 8, in the embodiment of the present invention, the limiting member 2102 may be selected from a plurality of protruding blocks 33 protruding on the outer circumferential surface of the connecting pipe 2101, or a shoulder-shaped flange extending along the circumferential direction thereof. In this embodiment, it is preferable that a shoulder-shaped flange is integrally formed on the outer peripheral surface of the connection pipe 2101, so that the connection pipe is subjected to a relatively uniform force when being in limit abutment with another member, and the connection pipe is convenient to process.

It will be appreciated that in practice, the air duct 15 is not limited to the above embodiment, but is inserted into the oil storage chamber 12. For example, as shown in fig. 11, in the third embodiment of the present invention:

the air duct 15 can also be accommodated outside the oil storage cavity 12, and an avoiding hole 121 communicated with the air duct 15 is formed at a hollow position of the inner cavity wall of the oil storage cavity 12, which is opposite to the air duct 15. The other parts are substantially the same as the second embodiment of the present invention, and are not described herein.

When the atomizing core member 200 is pre-assembled to the first position of the base member 100, the connecting tube 2101 of the first portion 210 is inserted into the air guide tube 15 after passing through the mounting chamber 31, the oil storage chamber 12 and the relief hole 121 in sequence. When the atomizing core 200 moves from the first position to the second position, the oil guiding hole 230 is located in the oil storage cavity 12 to prevent the oil leakage phenomenon during transportation, which also belongs to the protection scope of the present invention.

Further, as shown in fig. 11, to prevent oil from leaking out from a gap between the connection pipe 2101 and the relief hole 121. The utility model discloses in the third embodiment, the connecting pipe 2101 with it still is equipped with the seal cover 122 to dodge between the hole 121, the internal surface of seal cover 122 cup joint in the periphery of connecting pipe 2101, the peripheral surface of seal cover 122 with it is grease-proofing in order to seal up to dodge the interior pore wall elasticity butt of hole 121.

Specifically, as shown in fig. 11, the sealing sleeve 122 is further provided with a sealing groove 1221 along a circumferential direction thereof, so that the sealing sleeve 122 has an approximately i-shaped cross section, and two groove walls of the sealing groove 1221 form elastic clamping arms. When the sealing sleeve 122 is preassembled in the avoiding hole 121, the two elastic clamping arms respectively cover the end edges at the two ends of the avoiding hole 121, so that the inner hole wall of the avoiding hole 121 is covered, and the two elastic clamping arms clamp the end edges at the two ends of the avoiding hole 121 in the sealing groove 1221 for fixation. The sealing sleeve 122 is effectively prevented from being separated from the avoiding hole 121.

It can be understood that, in the practical application process, the sealing sleeve 122 is not limited to the above-mentioned manner of forming the sealing groove 1221 to be pre-installed in the avoiding hole 121. For example, the length of the sealing sleeve 122 may be set to be greater than the depth of the relief hole 121. Cup joint seal cover 122 again in the part periphery of first part 210, so that atomizing core 200 is located during base member 100 primary importance and second place, seal cover 122's peripheral surface all the time with the airtight butt of the interior pore wall of dodging hole 121, and then effectively prevent that fluid from following seal cover 122 with the mode of the production of the gap spills phenomenon between the hole 121 of dodging also belongs to within the scope of protection of the utility model.
