The inventor of this application discovers through long-term research, current electronic atomization device is when being used, and atomizing device is in the course of the work and carries out atomizing work constantly, because the tobacco juice is constantly consumed, lead to the continuous grow of cavity negative pressure of the interior storage tobacco juice of atomizing device, because the existence of negative pressure leads to the lower liquid of tobacco juice not smooth, and because the tobacco juice does not obtain timely replacement, still can produce burnt flavor, so not only can damage the product, still can bring not good use experience for the user. In order to solve the above problems, the present application provides some embodiments as follows based on many efforts and hard works made by the inventors.

Referring to fig. 1 to 2, the first embodiment of the atomizer of the present invention mainly includes a cartridge tube 11, a heat generating component 12, and a first sealing member 13.

Wherein the cartridge tube 11 is formed with a reservoir 1101 for storing a liquid smoke. The heating component 12 is used for heating and atomizing the smoke liquid from the liquid storage cavity 1101 to form smoke. For example, the reservoir 1101 and the heating element 12 may be in fluid communication, the liquid from the reservoir 1101 may flow onto the heating element 12, and the heating element 12 may generate heat to atomize the liquid under operation of an electric current. The first sealing member 13 is disposed between the smoke tube 11 and the heating element 12 to achieve sealing, and mainly prevents the smoke liquid flowing from the liquid storage chamber 1101 to the heating element 12 from leaking. In this embodiment, an air guide passage 10 is formed between the first sealing member 13 and the cartridge tube 11, and air can be guided into the liquid storage chamber 1101 while the first sealing member 13 seals.

This embodiment is through forming the air guide passageway between first sealing member 13 and cartridge tube 11, can be smoothly with air guide entering stock solution chamber 1101 in, the pressure in balanced stock solution chamber 1101 improves the tobacco juice that leads to because the tobacco juice of stock solution chamber 1101 is constantly consumed the negative pressure that produces and the not smooth scheduling problem of liquid under the tobacco juice, promotes and uses experience, can simplify the structure simultaneously.

with continued reference to fig. 1-3, in the present embodiment, the cartridge tube 11 includes a first tube wall 111 enclosing a reservoir 1101, and the liquid is stored in the reservoir 1101 enclosed by the first tube wall 111.

Optionally, the cartridge tube 11 may be, for example, a tubular arrangement, and the specific shape may be set according to actual requirements. The cartridge tube 11 is provided with the reservoir 1101, the smoke passage 1102, and the air intake passage 1103 along the axial direction thereof. The reservoir 1101, the smoke channel 1102 and the air inlet channel 1103 are arranged at intervals, for example, the reservoir 1101, the smoke channel 1102 and the air inlet channel 1103 are not communicated with each other in the cartridge tube 11.

For example, the cartridge tube 11 may include a first tube wall 111 and a second tube wall 113. The first tube wall 111 encloses a reservoir 1101. The number of the second pipe walls 113 is, for example, 2, and the second pipe walls 113 are respectively connected to the outer surface of the first pipe wall 111 in a bent manner so as to respectively enclose the inlet passage 1103 and the flue gas passage 1102 with the first pipe wall 111. In this embodiment, the air inlet channel 1103 is used for guiding the air outside the atomizing device 1 to the position of the heat generating component 12, and the air flow formed by the air brings the smoke formed by the heat generating component 12 into the smoke channel 1102, so as to be guided to the suction position, such as a cigarette holder, by the smoke channel 1102.

for example, the atomization device 1 is further provided with an air inlet hole 100, which is communicated with the air inlet channel 1103, and air outside the atomization device 1 can enter the air inlet channel 1103 through the air inlet hole 100.

Specifically, the second pipe walls 113 are located on two sides of the first pipe wall 111, the flue gas channel 1102 and the reservoir 1101 are separated by the first pipe wall 111, and the inlet channel 1103 and the reservoir 1101 are also separated by the first pipe wall 111. Optionally, the cartridge tube 11 is integrally formed, i.e. the first tube wall 111 and the second tube wall 113 are integrally formed. In the present embodiment, the extension length of the second tube wall 113 may be greater than the extension length of the first tube wall 111 on the side adjacent to the heat generating component 12.

In this embodiment, the heat generating component 12 may be at least partially disposed within the first tube wall 111, such as embedded within the first tube wall 111 from an end of the reservoir 1101. The first sealing member 13 abuts between the inner surface of the first tube wall 111 and the outer surface of the heat generating component 12 to seal, wherein the air guide passage 10 is formed between the first sealing member 13 and the inner surface of the first tube wall 111. For example, when the inner surface of the first tube wall 111 facing the heat generating component 12 is provided with a protrusion structure or a groove structure, and the first sealing member 13 abuts against the inner surface of the first tube wall 111, the protrusion structure or the groove structure can enable a gap to exist between the first sealing member 13 and the first tube wall 111, so as to form the air guide channel 10.

In another embodiment, the heat generating component 12 may be located completely below the first tube wall 111, and the first sealing member 13 with different shapes may be used to communicate the reservoir 1101 with the heat generating component 12. In this embodiment, the first sealing member 13 may abut between the first tube wall 111 and the heat generating component 12 for sealing, and the air guide channel 10 may be formed between the first sealing member 13 and the first tube wall 111 by a protrusion structure or a groove structure.

Referring to fig. 3 to 5, in the present embodiment, a plurality of first ribs 1110 are disposed at intervals on an inner surface of one end of the first tube wall 111 adjacent to the heating element 12, and the first ribs 1110 protrude from the inner surface of the first tube wall 111. When the first seal 13 abuts against the first rib 1110, the air guide passage 10 is formed by the gap between the inner surface of the first tube wall 111 and the first seal 13. Specifically, when the first seal 13 abuts against the inner surface of the first tube wall 111, since the first rib 1110 protrudes from the inner surface of the first tube wall 111, a gap is provided at a position adjacent to the first rib 1110, and thus the presence of the gap forms the air guide channel 10.

Optionally, as shown in fig. 2 and 4, the inner surface of the first tube wall 111 adjacent to one end of the heat generating component 12 is provided with a flange 112 in the circumferential direction. The flange 112 may be used, for example, to stop the heat-generating component 12 and facilitate sealing between the flange 112 and the heat-generating component 12. The first sealing member 13 is clamped between the flange 112 and the heating element 12 to simultaneously contact the flange 112 and the heating element 12 for sealing, and further prevent the smoke liquid in the liquid storage chamber 1101 from leaking when flowing onto the heating element 12. In the present embodiment, the flange 112 is integrally formed on the inner surface of the first tube wall 111. Of course, in other embodiments, the cartridge tube 11 may not be integrally formed, and the flange 112 may be removably disposed on the inner surface of the first tube wall 111, for example. The outer edge of the flange 112 defines a hole, i.e., the middle portion of the flange 112 is a hollow hole, so that the smoke liquid flows through the hole to the heat generating component 12 in the liquid storage chamber 1101. In this embodiment, the air guide passage 10 is formed between the first seal member 13 and the inner surface of the first duct wall 111 and the flange 112. In this embodiment, air can enter the liquid storage chamber 1101 through the air guide channel 10, and the pressure difference between the inside and the outside of the liquid storage chamber 1101 can be balanced to some extent.

The atomizing device 1 of this embodiment is in the course of the work, for example, the user is when the suction, because the effect of suction pressure, make the air enter into atomizing device 1 from inlet port 100 and form mobile air current, the tobacco juice flows and generates heat the atomizing and become smog on heating element 12, smog enters into flue gas channel 1102 along with the flow of air current, it supplies the user to absorb to flow to the absorption position at last, because air guide channel 10 can lead the air to in stock solution chamber 1101, can balance the pressure differential inside and outside stock solution chamber 1101 to a certain extent, can improve because the tobacco juice consumes the problem of the continuous grow of the inside negative pressure of stock solution chamber 1101, thereby it is smooth and easy to have guaranteed that the lower liquid of tobacco juice is smooth, can effectively improve the problem that current electronic atomization equipment produced burnt flavor, promote and use experience.

Referring to fig. 2, the protruding direction of the flange 112 may be perpendicular to the inner surface of the first tube wall 111 adjacent to the heat generating component 12 or perpendicular to the axial direction of the cartridge tube 11.

Referring to fig. 4 and 5, the surface of the flange 112 facing the first sealing member 13 is optionally provided with second ribs 1120 at intervals. The second rib 1120 is formed to protrude from the surface of the flange 112, and when the first sealing member 13 abuts against the second rib 1120, a gap may exist between the flange 112 and the first sealing member 13 due to the height of the second rib 1120, and at least a gap may be formed near the first rib 1110. When the first sealing member 13 abuts between the flange 112, the inner surface of the first tube wall 111 and the heat generating component 12, gaps are formed between the first rib 1110 and the second rib 1120, which are communicated with each other, so that the air guide channel 10 can be formed, and thus air can smoothly enter the liquid storage cavity 1101 through the air guide channel 10.

In this embodiment, the first rib 1110 and the second rib 1120 may be integrally formed by the cartridge tube 11. Meanwhile, the inner surface of the protruding first tube wall 111 and the flange 112 of the first rib 1110 and the second rib 1120 are adopted, so that the smoke bomb tube 11 can be more easily demoulded during injection molding.

For example, in the assembly process, the first sealing element 13 is firstly sleeved on the periphery of the heating element 12, and then the heating element 12 sleeved with the first sealing element 13 is embedded into the space surrounded by the first tube wall 111 through the end of the first tube wall 111 adjacent to the heating element 12, so that the first sealing element 13 can simultaneously contact the inner surface of the first tube wall 111 and the flange 112, and thus, the sealing can be performed more effectively. Due to the height of the first ribs 1110, there is also a gap between the first seal 13 and the inner surface of the first tube wall 111, at least in the vicinity of the first ribs 1110. By the cooperation of the first ribs 1110 and the second ribs 1120, the air guide channel 10 is formed by the gap existing between the inner surface of the first sealing member 13 and the end of the first tube wall 111 adjacent to the heat generating component 12 and the flange 112, and air can smoothly enter the liquid storage chamber 1101 through the air guide channel 10. In this embodiment, by providing the first rib 1110 and the second rib 1120, the air guide channel 10 can be effectively formed, so that air can smoothly enter the liquid storage cavity 1101, and the pressure in the liquid storage cavity 1101 is balanced to avoid the problems of unsmooth liquid discharge caused by negative pressure.

With continued reference to fig. 4 and 5, optionally, one end of the second rib 1120 extends to the outer edge of the flange 112, and the other end of the second rib 1120 extends to the connection point of the flange 112 and the first tube wall 111, for example, the second rib 1120 may extend in a substantially straight line. One end of the first rib 1110 is connected to the second rib 1120, the other end of the first rib 1110 extends to the edge of the end of the first tube wall 111 close to the heating element 12, and the first rib 1110 may also extend substantially linearly. In this embodiment, the second rib 1120 and the first rib 1110 are connected together, so that the air guide channel 10 can be formed to guide air more smoothly. Of course, in other embodiments, the line type of the second rib 1120 and the first rib 1110 is not limited, and may be, for example, a curve, an arc, etc. In other embodiments, the second rib 1120 and the first rib 1110 may be spaced apart, for example, the position of the second rib 1120 at the joint of the flange 112 and the first tube wall 111 is offset from the position of the first rib 1110 at the joint of the flange 112 and the first tube wall 111.

The distance between two adjacent first ribs 1110 on the same side, for example, 1-3mm, can be designed according to actual requirements.

with continued reference to fig. 4, the number of the second ribs 1120 is optionally 2-8, and the second ribs are correspondingly disposed on two opposite sides of the surface of the flange 112 facing the heat generating component 12. One part of the second ribs 1120 may be disposed on one side, and the other part of the second ribs 1120 may be disposed on the other side opposite to the one side, for example, when the number of the second ribs 1120 is 4, 2 ribs are disposed on one side, and the other 2 ribs are disposed on the other side. The second ribs 1120 on each side are spaced apart from each other, or arranged in a spaced-apart manner. The distance between two adjacent second ribs 1120 on the same side, for example, 1-3mm, can be designed according to actual requirements. The number of the first ribs 1110 and the number of the second ribs 1120 may be the same or different, for example, the number of the first ribs 1110 is the same as that of the second ribs 1120, and the 4 first ribs 1110 are respectively connected to the 4 second ribs 1120.

In other embodiments, the second rib 1120 may also be disposed on the surface of the flange 112 facing the first seal 13 along the circumferential direction, which is the circumferential direction formed by the second rib 1120, and the extending length of the second rib 1120 is smaller than the circumference of the outer edge of the flange 112, so that the situation that the air cannot be guided due to the closed loop formed by the second rib 1120 on the surface of the flange 112 can be avoided. That is, in the present embodiment, the line type and the extending direction of the second rib 1120 and the first rib 1110 are not limited, but when the second rib 1120 is circumferentially disposed on the surface of the flange 112, the extending length of the second rib 1120 is smaller than the circumference of the outer edge of the flange 112. Similarly, when the first rib 1110 is circumferentially disposed on the inner surface of the first tube wall 111, the extension length of the first rib 1110 is less than the perimeter of the cross section of the inner surface of the first tube wall 111 in the direction perpendicular to the axis thereof.

Optionally, in this embodiment, the height of the first rib 1110 protruding from the inner surface of the first tube wall 111 facing the heat generating component 12 is 0.05mm to 0.2mm, optionally 0.07mm to 0.15mm, and optionally 1mm to 0.12 mm. Optionally, the width of the first rib 1110 in a direction perpendicular to the height direction thereof is 0.07mm to 0.2mm, optionally 0.09mm to 0.12 mm. In the present embodiment, when the first rib 1110 extends substantially linearly, the width direction of the first rib 1110 is substantially perpendicular to the extending direction and the height direction thereof. Optionally, the height of the second rib 1120 protruding from the surface of the flange 112 facing the heat generating component 12 is 0.05mm to 0.2mm, optionally 0.07mm to 0.15mm, and optionally 0.1mm to 0.12 mm. Optionally, the width of the second rib 1120 in the direction perpendicular to the height direction thereof is 0.07mm to 0.2mm, optionally 0.09mm to 0.12 mm. In the present embodiment, when the second rib 1120 extends substantially linearly, the width direction of the second rib 1120 is substantially perpendicular to the extending direction and the height direction. After long-time tests, the inventor finds that when the height of the first ribs 1110 and the height of the second ribs 1120 are both 0.05mm-0.2mm and the width is 0.05mm-0.2mm, the formed air guide channel 10 can well guide air, and meanwhile, smoke liquid can be prevented from leaking from the air guide channel 10.
