The terms "coupled" and "connected," as used herein, are intended to encompass both direct and indirect coupling (coupling), unless otherwise indicated.

Example 1

Referring to fig. 1-7, an atomization heating structure includes: heating tube 10, insulating tube 20, first end cap 40, and second end cap 50.

The space within the heat generating tube 10 forms a first chamber for placing the member to be atomized. The heat insulating pipe 20 is sleeved outside the heating pipe 10. The first end cap 40 is disposed at one end of the insulating tube 20, and the second end cap 50 is disposed at the other end of the insulating tube 20.

The heating tube 10, the heat insulating tube 20, the first end cap 40 and the second end cap 50 form a second chamber. The first end cap 40 is provided with an air flow hole 43, and the air flow hole 43 is communicated with the second chamber. The second chamber communicates with the first chamber proximate the second end cap 50.

With the atomizing heating structure in the above embodiment, the first chamber is formed in the heat generating tube 10, and the second chamber is formed between the heat generating tube 10, the heat insulating tube 20, the first end cap 40, and the second end cap 50. The first end cap 40 is provided with an air flow hole 43, the air flow hole 43 is communicated with a second chamber, the second chamber is communicated with the first chamber, and the third chamber is a relatively sealed chamber. Thus, when the user sucks the workpiece to be atomized, on one hand, the heating tube 10 can heat and atomize the workpiece to be atomized, on the other hand, under the action of the user suction, external air flows into the second chamber and the first chamber in sequence through the air flow holes 43, and when the air flows in the second chamber, the air flows can perform heat exchange with heat on the outer wall of the heating tube 10, so that the air flow is heated, part of heat is taken away, the heated air flow continuously flows to the first chamber, and then the workpiece to be atomized is heated in a hot air flow mode. I.e. the atomizing heating structure, not only can heat the to-be-atomized piece through the heating pipe 10, but also can heat the air flow without adding a heat exchange piece. The atomization heating structure designed by the application has the advantages of simple structural design, low cost, high heating efficiency and low power consumption.

The side of the second end cover 50 facing the first end cover 40 is provided with a first limiting part 52, the side of the heat insulation pipe 20 facing the second end cover 50 is provided with a second limiting part 21, and the first limiting part 52 and the second limiting part 21 are connected to limit the position of the heat insulation pipe 20. By providing the first stopper 52 and the second stopper 21, the relative position of the heat insulating tube 20 to the heat generating tube 10 or other components can be effectively restricted. The first limiting portion 52 and the second limiting portion 21 may be in a concave-convex connection structure, for example, any one of the first limiting portion 52 and the second limiting portion 21 is in a groove structure, the other one of the first limiting portion 52 and the second limiting portion 21 is in a convex structure, or the adjacent sides of the first limiting portion 52 and the second limiting portion 21 are respectively provided with a meshed tooth portion. The first limiting portion 52 and the second limiting portion 21 may also be adsorption structures, for example, corresponding magnetic sheets are disposed on one side of the first limiting portion 52 and the second limiting portion 21 close to each other, so as to limit the position of the heat insulation tube 20.

The space width of the second chamber in the radial direction is not too large nor too small. When the space width in the radial direction of the second chamber is excessively large, the heat exchange efficiency is easily deteriorated by the air flow (i.e., air) in the second chamber being too far away from the heat generating pipe 10. When the space width in the radial direction of the second chamber is too small, on one hand, processing difficulty exists, and on the other hand, the space in the second chamber is too small, and the air flow is affected. Based on the foregoing considerations, the space width in the radial direction of the second chamber is set to L,0.1 < L < 2mm.

Referring to fig. 7, a first supporting body 51 is protruding from a side of the second end cover 50 facing the first end cover 40, and the heat generating tube 10 abuts against the first supporting body 51, so that a bottom wall of the second end cover 50 facing the side of the first end cover 40 and the heat generating tube 10 are spaced apart to form a connecting portion 60 for communicating the first chamber and the second chamber. Specifically, the first supporting body 51 has a bar-like, columnar, block-like or grid-like structure. When the first supporting body 51 is a strip structure, for example, a strip structure disposed along a radial direction of the heat generating tube 10, a portion of the surface thereof is used to contact the heat generating tube 10 and the heat insulating tube 20, and the connection portion 60 is a communication groove formed between the first supporting body 51 and a surrounding structure (for example, the second end cap 50), and the communication groove spans the heat generating tube 10 along the radial direction of the second end cap 50 to communicate the second chamber with the first chamber. When the first supporting body 51 is a columnar structure, it may be provided in a plurality of independent spaced-apart columnar structures, part of which is used to contact the heating tube 10 and the other part is used to contact the heat insulation tube 20, and the plurality of columnar structures divide the space between the heating tube 10 (or the heat insulation tube 20) and the second end cap 50 into a plurality of small spaces (i.e., the connection parts 60) communicating with each other so that the first chamber and the second chamber communicate with each other. When the first support 51 is a grid-like structure, the hollow grid in the grid-like structure may be utilized to serve as the connection 60 to connect the first chamber and the second chamber, for example, the second support 22 is designed in a grid shape of 2×2. When the first supporting body 51 has a block structure, referring to fig. 7, the first supporting body 51 may have a block structure including a central body and a peripheral strip structure, and the space between the heating tube and the first end cover is divided into a plurality of small spaces (i.e. the connecting portions 60) by the peripheral strip structure so as to communicate the first chamber with the second chamber.

The first supporting body 51 is disposed at a side relatively close to the bottom of the heating tube 10, so that when the external air flows from the air flow hole 43 to the second chamber, the external air needs to move along the axial direction of the heating tube 10 from the top of the heating tube 10 to the bottom of the heating tube 10, and finally enters the first chamber through the connection portion 60 between the second chamber and the first chamber at the bottom of the heating tube 10, that is, enters from the bottom of the to-be-atomized piece in the heating tube 10. The communication structure can effectively prolong the time or path of the air flow to be heated, thereby enhancing heat exchange, reducing power consumption and increasing the heating efficiency of the to-be-atomized piece in the heating tube 10.

Specifically, when the first supporting body 51 is of the structure shown in fig. 7, referring to fig. 1 and 7, the first limiting portion 52 is a structure protruding toward one side of the heating tube 10 on the first supporting body 51, the second limiting portion 21 is a notch or a groove formed on one end of the heat insulating tube 20 near the second end cap 50, and the second limiting portion 21 is in concave-convex fit with the strip-shaped first supporting body 51 at the first limiting portion 52, so as to prevent the heat insulating tube 20 from rotating or moving in the protective tube 30. The end of the heating tube 10 is sleeved on the inner side of the first limiting part 52, the end of the heat insulation tube 20 is sleeved on the outer side of the first limiting part 52, and the heating tube 10 and the heat insulation tube 20 can be effectively spaced apart through the first limiting part 52 so as to guarantee the space in the second cavity. The first limiting portion 52 and the first supporting body 51 are integrally formed or independently formed. When the first limiting portion 52 and the first supporting body 51 are independent structures, the first limiting portion 52 may be fixed on the first supporting body 51 by welding, bonding, screwing, or the like.

The atomizing heating structure further comprises a protective tube 30, the protective tube 30 is sleeved on the outer side of the heat insulation tube 20, and the heat insulation tube 20, the protective tube 30, the first end cover 40 and the second end cover 50 are enclosed to form a third chamber. Wherein the inner wall of the protective tube 30 is provided with a reflective insulation layer and/or a thermal insulation member is provided in the third chamber.

The inner wall of the heat insulating pipe 20 is provided with a second supporting body 22, and the second supporting body 22 is used for providing radial support for the heat insulating pipe 20, and/or the second supporting body 22 is used for assisting the air flow in the second chamber to exchange heat. If the heat-insulating tube 20 is made of soft silica gel, the second supporting body 22 is provided to provide radial support for the heat-insulating tube 20, so as to prevent the heat-insulating tube 20 from shrinking and deforming to the side of the heat-insulating tube 10, in order to avoid the heat-insulating tube 20 from being adsorbed or extruded to the side close to the heat-insulating tube 10 when the user sucks the to-be-atomized piece. If the heat insulating pipe 20 is made of a plastic-like, relatively rigid material, the radial support function can be achieved without providing the second support 22. Wherein the second support 22 may be in contact with the outer wall of the heat generating tube 10 or spaced apart by a small distance, for example, a distance of 1 mm.

The second support 22 has a bar-like or block-like structure. When the second support 22 is in a strip structure, for example, referring to fig. 1, the second support 22 is in a plurality of strip structures circumferentially arranged on the inner wall of the heat insulation pipe 20 at intervals, and the length direction of the second support 22 is along the axial direction of the heat insulation pipe 20. Alternatively, referring to fig. 6, the second supporting bodies 22 are a plurality of strip-shaped structures disposed at intervals along the axial direction of the inner wall of the heat insulation pipe 20, but the length direction of the second supporting bodies 22 is along the circumferential direction of the heat insulation pipe 20. Still alternatively, the second support 22 may have a spiral strip-like structure provided on the inner wall of the heat insulating pipe 20. The second support 22 can effectively provide radial support to the insulating tube 20 when the length direction of the second support is along the axial direction of the insulating tube 20. When the second support body 22 is in a spiral strip structure along the length direction of the Zhou Xianghuo second support body 22 of the heat insulation pipe 20, not only a radial supporting effect can be provided for the heat insulation pipe 20, but also the space in the second cavity can be divided into a plurality of flow channels, so that the time of air flow in the second cavity can be effectively increased, and the air flow can obtain a sufficient heat exchange effect. When the second support 22 is in a block structure, for example, a plurality of curved protrusions are disposed on the inner wall of the heat insulation tube 20, so as to not only provide radial support for the heat insulation tube 20, but also scatter the airflow flowing into the second chamber, thereby enabling the airflow in the second chamber to flow in a disordered manner to enhance the heat exchange efficiency.

Referring to fig. 4-5, the first end cap 40 includes a cap 41 and a pre-tightening ring 42, an insertion opening is formed in the cap 41, the insertion opening is used for inserting a to-be-atomized member into the first chamber, the pre-tightening ring 42 is disposed in the insertion opening, and the pre-tightening ring 42 is used for being attached to an outer wall of the to-be-atomized member. An air flow hole 43 is provided in the first end cap 40 between the cap body 41 and the pre-tightening ring 42. A plurality of third supporting bodies 44 which are distributed at intervals are arranged on the inner wall of the cover body 41 along the circumferential direction, and two sides of the third supporting bodies 44 are respectively connected with the cover body 41 and the pre-tightening ring 42. The inner wall of the cover 41, the outer wall of the pre-tightening ring 42 and the adjacent two third supports 44 may form one air flow hole 43. More preferably, the third support 44 has a plate-like structure, and the third support 44 and the inner wall surface of the cover 41 are substantially perpendicular to each other. The axial dimension of the third support body 44 along the heating tube 10 is greater than the axial dimension of the pre-tightening ring 42 along the heating tube 10, so that the third support body 44 can have more contact surfaces with the to-be-atomized piece in the heating tube 10, and the supporting and fixing effects of the to-be-atomized piece can be enhanced.

The pre-tightening ring 42 is made of elastic material, such as silica gel, and the pre-tightening ring 42 made of elastic material not only can provide a certain pre-tightening force for a piece to be atomized (such as a cigarette to be atomized and burnt), but also can ensure tightness of a joint between the pre-tightening ring and the piece to be atomized. The heating element on the heating tube 10 may be a heating wire spirally wound on the wall of the heating tube 10, or a heating sheet printed on the wall of the heating tube 10. The heat insulating tube 20 is made of a low heat conductive material, such as plastic, silica gel, aerogel, etc. The third chamber outside the heat insulating pipe 20 is a relatively sealed chamber, which can perform a heat insulating function to avoid low energy utilization or large energy loss caused by heat dissipation.

Referring to fig. 3, the inserted part to be atomized of the heating tube 10 is not shown. When the user sucks the workpiece to be atomized, the external air flows to the second chamber through the air flow hole 43, and after the air flows in the second chamber, a certain amount of heat is obtained, namely the air is heated by the heat on the outer wall of the heating tube 10, and flows into the first chamber through the communication part of the second chamber and the first chamber at the bottom of the heating tube 10, so as to heat the workpiece to be atomized in the first chamber by hot air flow.

Example 2

The atomization heating structure in this embodiment is the same as that of the connection portion 60 in embodiment 1 except for the connection portion 60, so only the connection portion will be described in this embodiment, and the same portions as those of embodiment 1 will not be described again.

In the embodiment of the present application, the connection portion 60 is an air guide hole 11 formed on the wall of the heating tube 10. The second chamber is communicated with the first chamber in the heating tube 10 through the air guide holes 11 on the wall of the heating tube 10. In this way, when the user sucks the to-be-atomized member, the heated air flow in the second chamber can be guided into the first chamber by the generated suction force so as to perform air flow heating on the to-be-atomized member in the first chamber.

Specifically, a plurality of air guide holes 11 are formed in the wall of the heating tube 10, and the plurality of air guide holes 11 are distributed at intervals along the axial direction of the heating tube 10, so that heated air flows at different axial positions along the heating tube 10 can flow into the first cavity nearby and heat to-be-atomized pieces at different axial positions.

More preferably, referring to fig. 6, the heat generating tube 10 has a first end 12 (top end) and a second end 13 (bottom end) opposite to each other, the first end 12 being disposed adjacent to the first end cap 40, and the second end 13 being disposed adjacent to the second end cap 50. The spacing between the air holes 11 near the first end 12 and the first end 12 of the heating tube 10 is larger than the spacing between the air holes 11 near the second end 13 and the second end 13 of the heating tube 10, and/or the air holes 11 on the heating tube 10 become larger from the side of the first end 12 to the side of the second end 13.

If the air guide hole 11 is formed at a position close to the first end 12, the residence time of the air flow in the second chamber is reduced, the sufficient heat exchange effect is affected, and the air flow may be guided into the first chamber before the heat exchange is performed, so that ineffective or inefficient heating is generated. Therefore, the distance between the air hole 11 near the first end 12 and the first end 12 on the heating tube 10 is larger than the distance between the air hole 11 near the second end 13 and the second end 13 on the heating tube 10, so that after the air flow enters the second chamber, sufficient heat exchange can be obtained.

The closer the air vent 11 is to the first end 12, the lower the degree of heating of the air flow in the second chamber, and the closer the air vent 11 is to the second end 13, the higher the degree of heating of the air flow in the second chamber. Therefore, the air-guide hole 11 on the heat pipe 10 becomes larger from the side of the first end 12 to the side of the second end 13 to limit the air flow quantity of the air-guide hole 11 near the side of the first end 12 and secure the heat exchanging effect and the air-flow heating effect of the air flow near the side of the second end 13. The air vent 11 may be a circular hole, a square hole, a bar-shaped hole, or the like, and the larger the air vent 11 is, the larger the airflow flux it can obtain. Taking the gas vent 11 in the shape of a bar as an example, the gas vent 11 is large, for example, the size along the circumferential direction of the heat insulating pipe 20 is large, or the size along the axial direction of the heat insulating pipe 20 is large.

Referring to fig. 6, when a user uses the atomization heating mechanism to heat the to-be-atomized member, after the user sucks the to-be-atomized member, the airflow in the second chamber can heat the to-be-atomized member at different positions through the plurality of air guide holes 11 on the heating tube 10. In the embodiment of the present application, the air flow can enter the first chamber through the air guide hole 11 on the heating tube 10 without providing the first supporting body 51 on the second end cover 50.

The above-mentioned atomizing heating structure that this application designed is divided into three cavity from inside to outside, and first cavity is used for placing and waits to atomize the piece, and the second cavity is used for heating the air current and retrieving energy, and the third cavity is used for thermal-insulated in order to reduce energy loss. The atomization heating structure can utilize the energy of the circumferential heating tube 10 to heat the air flow, when a user sucks, the air flow reaches the bottom of the first chamber along the outer wall of the heating tube 10 (or passes through the air guide hole 11) and then enters the first chamber to heat the to-be-atomized piece, meanwhile, the heating tube 10 heats the to-be-atomized piece through heat transfer, so that the heating tube 10 can generate hot air flow to heat the to-be-atomized piece while circumferentially heating the to-be-atomized piece. The atomizer comprises the above-mentioned atomizing heating structure and thus also has the advantages of the above-mentioned atomizing heating structure, and will not be described.
