Description

[0001] The present application relates to the technical field of electronic atomization equipment, and more specifically, to an aerosol generating device. Background Art

[0002] With the advent of atomizer products, there are more and more styles of atomizers on the market. In the existing technology, an atomizer usually includes a liquid cup and an atomizing assembly. The atomizing assembly is assembled in the liquid cup, and the aerosol matrix is ​​heated at high temperature to form high-temperature steam. The atomizing assembly usually includes components such as a liquid guide, a liquid tank, a heating wire, and an electrode. The liquid guide contacts the aerosol matrix and the heating wire in the liquid tank respectively. The heating wire is connected to the electrode. When the electrode is energized, a high-temperature atomized aerosol matrix is ​​generated to form an aerosol. However, during atomization, the pressure in the liquid cup continues to decrease as the atomization process proceeds. When the atomizing assembly is in a negative pressure state, the aerosol matrix in the atomizing assembly does not flow smoothly, resulting in insufficient liquid supply to the atomizing core, or even an inability to supply liquid to the atomizing core, which easily produces a burnt smell, making the quality of the atomizer unreliable and greatly affecting the user experience. Therefore, the existing technology cannot meet our needs. Utility Model Content

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0028] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0030] Please see the attached Figure 1 To the attached Figure 9As shown, the embodiment of the present application provides a dust cover structure, an aerosol generating device, comprising: a liquid cup 1, an atomizer core assembly 100 arranged in the liquid cup 1, the atomizer core assembly 100 including an atomizer tube 2, a liquid guide member 3 arranged in the atomizer tube 2, and an air guide passage 200 provided between the atomizer tube 2 and the liquid guide member 3. When negative pressure is generated in the atomizer core assembly 100, air can enter the atomizer core assembly 100 through the air guide passage 200 to adjust the internal air pressure of the atomizer core assembly 100, so that the air pressure in the atomizer core assembly 100 is balanced with the air pressure of the liquid cup 1, thereby improving the liquid supply capacity of the liquid guide member 3, thereby avoiding the problem of poor liquid supply caused by the imbalance of air pressure in the atomizer core assembly 100, preventing the atomizer core assembly 100 from dry burning, improving the performance of the aerosol generating device, and enhancing the user experience.

[0031] As attached Figure 1 To the attached Figure 5 As shown, further, the air guide passage 200 is configured as an air guide groove, which is provided on the liquid guide member 3 and located on the circumferential surface of the outer side of the liquid guide member 3. The air guide passage 200 is directly provided on the outer circumferential surface of the liquid guide member 3. The structure is simple and the processing is convenient. The air guide passage 200 can timely adjust the internal air pressure of the atomizer core assembly 100 so that the air pressure in the liquid guide member 3 is balanced with the air pressure in the liquid cup 1, thereby avoiding the problem of poor liquid supply caused by the imbalance of the air pressure in the liquid guide member 3, preventing the atomizer core assembly 100 from dry burning, and avoiding the generation of burnt smell.

[0032] It can be understood that the depth of the air guiding path 200 refers to the distance extending from the outer peripheral surface of the liquid guiding part 3 to the axial direction of the liquid guiding part 3, that is, the distance extending inward, and the width of the air guiding path 200 refers to the size of the opening of the air guiding path 200 on the outer peripheral surface of the liquid guiding part 3 perpendicular to the extension direction of the depth of the air guiding path 200, that is, the distance between the two side walls of the air guiding path 200.

[0033] As attached Figure 1 To the attached Figure 5As shown, further, the atomizer tube 2 is provided with a receiving cavity 22 for accommodating the liquid guide member, and the air guide passage 200 is configured as an air guide groove, which is provided on the atomizer tube 2 and is located on the inner wall of the receiving cavity 22 on the inner side of the atomizer tube 2. The air guide passage 200 can timely adjust the internal air pressure of the atomizer core assembly 100 so that the air pressure in the liquid guide member 3 is balanced with the air pressure in the liquid cup 1, thereby avoiding the problem of poor liquid supply caused by the imbalance of the air pressure in the liquid guide member 3, preventing the atomizer core assembly 100 from dry burning, and avoiding the generation of a burnt smell. At the same time, the air guide passage 200 can be provided on either the liquid guide member 3 or the atomizer tube 2, which is flexible in design, improves the performance of the aerosol generating device, and enhances the user experience.

[0034] Specifically, the outer peripheral surfaces of the atomizing tube 2 and the air guide passage 200 are flat; and / or,

[0035] The outer peripheral surface of the atomizing tube 2 corresponding to the air guide passage 200 is convex.

[0036] As attached Figure 6 As shown in FIG. 1 , the outer peripheral surface of the atomizing tube 2 is flat, which is beneficial to improving the appearance of the atomizing tube 2 and making it beautiful. Figure 7 As shown, the outer peripheral surface of the atomizer tube 2 is arranged in a convex shape, so the position of the air guide passage 200 located in the accommodating cavity 22 can be accurately understood from the appearance of the atomizer tube 2, which facilitates the rotation of the air guide passage 200 to the required position during installation without reducing the thickness of the atomizer tube 2, thereby avoiding deformation and breakage of the atomizer tube 2.

[0037] It is understandable that Figure 6 As shown, the depth H of the air guiding passage 200 refers to the distance extending from the inner wall of the accommodating cavity 22 of the atomizer tube 2 in the direction away from the axial center of the atomizer tube 2, that is, the distance extending outward. The width D of the air guiding passage 200 refers to the size of the opening of the air guiding passage 200 on the inner wall of the accommodating cavity 22 perpendicular to the extension direction of the depth of the air guiding passage 200, that is, the distance between the two side walls of the air guiding passage 200.

[0038] As attached Figure 1 To the attached Figure 5 As shown, the air guide passage 200 has a depth of 0.05-2 mm and a width of 0.05-0.07 mm. The appropriate size can maintain the liquid-absorbing capacity of the liquid-guiding member 3 while also regulating the internal air pressure of the atomizer core assembly 100, thereby avoiding the problem of poor liquid supply caused by the imbalance of air pressure in the liquid-guiding member 3, which may result in the aerosol matrix inhaled into the user's mouth not being fully atomized, thereby causing problems such as "bubble stuck".

[0039] Specifically, the length of the air guide passage 200 may be 10-12 mm, and may be of equal length to the liquid guide member 3. It is understood that the depth of the air guide passage 200 is any one of 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2 mm, or a range formed by any two of the values. 0.1mm, 10.2mm, 10.3mm, 10.4mm, 10.5mm, 10.6mm, 10.7mm, 10.8mm, 10.9mm, 11mm, 11.1mm, 11.2mm, 11.3mm, 11.4mm, 11.5mm, 11.6mm, 11.7mm, 11.8mm, 11.9mm, 12mm, or a range formed by any two of the values; the width of the air guide passage 200 is 0.05mm, 0.06mm, 0.07mm, or a range formed by any two of the values.

[0040] Specifically, the air guiding passage 200 has a depth of 1 mm, a length of 11 mm, and a width of 0.06 mm, thereby improving the air guiding effect of the liquid guiding member 3 .

[0041] As attached Figure 1 To the attached Figure 5 As shown, the atomizer tube 2 is further provided with a liquid inlet hole 21, which is provided on the side or bottom of the atomizer tube 2. The liquid inlet hole 21 is provided corresponding to the air guide passage 200. The corresponding provision of the liquid inlet hole 21 and the air guide passage 200 allows the atomizer core assembly 100 to share a single passage for liquid inlet and air supply, further improving air supply efficiency and preventing problems such as "bubble stuck".

[0042] As attached Figure 1 To the attached Figure 4 and attached Figure 8 To the attached Figure 9 As shown, the liquid cup 1 is further provided with a sealing member 4, which is provided with a first air supply groove 41, which is in communication with the air guide passage 200. This further increases the air supply channel, prevents bubble jamming, facilitates rapid liquid guide, plays a role in moisturizing the atomizer core assembly 100, improves the liquid supply capacity of the liquid guide member 3, prevents the atomizer core assembly 100 from dry burning, improves the performance of the aerosol generating device, and enhances the user experience.

[0043] As attached Figure 1 To the attached Figure 4 and attached Figure 8 To the attached Figure 9 As shown, further, the first air supply groove 41 is provided with an air intake section 411 and a plurality of diverging sections 412 communicating with the air intake section 411. The air intake section 411 and the diverging section 412 are arranged in a direction away from the middle of the sealing member 4, and air diffuses from the air intake section 411 to the diverging section 412. External air enters the liquid cup 1 from the atomizer core assembly 100 to replenish the liquid cup 1 and prevent the generation of negative pressure. The plurality of diverging sections 412 facilitate the entry of gas from multiple channels, which is conducive to pressure relief, prevents the generation of negative pressure, improves the air supply efficiency, facilitates rapid liquid conduction, prevents bubble jamming, and plays a role in moisturizing the atomizer core assembly 100, preventing the atomizer core assembly 100 from dry burning, improving the performance of the aerosol generating device, and enhancing the user experience.

[0044] Specifically, the air inlet section 411 and the diverging section 412 are arranged in a direction away from the center of the seal 4. Specifically, the air inlet section 411 is close to the center of the seal 4, while the diverging section 412 is relatively far from the center of the seal 4. The air inlet section 411 is located between the diverging section 412 and the center of the seal 4. The first air supply groove 41 is cup-shaped. The diverging section 412 extends away from the center of the seal 4, enhancing the pressure relief function of the first air supply groove 41, preventing the generation of negative pressure and improving the user experience.

[0045] Furthermore, the projection of the liquid-guiding member 3 in the axial direction is located on the air inlet section 411 and the diverging section 412, so that the first air supply groove 41 is arranged corresponding to the liquid-guiding member 3, which facilitates the direct entry of gas into the liquid-guiding member 3, is beneficial to pressure relief, prevents the generation of negative pressure, improves the air supply efficiency, facilitates rapid liquid guidance, prevents bubble jamming, plays a role in moisturizing the atomizer core assembly 100, prevents the atomizer core assembly 100 from dry burning, improves the performance of the aerosol generating device, and enhances the user experience.

[0046] As attached Figure 1 To the attached Figure 4 and attached Figure 6 To the attached Figure 7As shown, the number of the diverging sections 412 is greater than the number of the air inlet sections 411, and the multiple diverging sections 412 intersect at a position close to the air inlet section 411. The seal 4 is provided with the diverging sections 412 with pressure relief function in multiple directions, thereby ensuring the stability of the atomizer during use, avoiding poor air release at certain angles, and preventing the negative pressure generated by liquid loss in the atomizer core assembly 100 from preventing the liquid from being transported to the heating element of the atomizer core assembly 100 through the liquid guide 3.

[0047] As attached Figure 1 To the attached Figure 4 and attached Figure 8 To the attached Figure 9 As shown, further, the width of the air intake section 411 is greater than the width of the diverging section 412. This is beneficial for the air intake section 411 to merge the gases of several diverging sections 412, thereby enhancing the pressure relief function of the first air replenishing groove 41, preventing the generation of negative pressure, and improving the user experience.

[0048] As attached Figure 1 To the attached Figure 4 and attached Figure 8 To the attached Figure 9 As shown, further, the sealing member 4 is provided with a second air supply groove 42. This further increases the pressure relief function of the sealing member 4, prevents the generation of negative pressure, and avoids problems such as bubble jamming.

[0049] Furthermore, the second air replenishing groove 42 is in an elongated strip structure, which enhances the air replenishing effect of the air replenishing channel, prevents bubble jamming, and facilitates rapid liquid conduction.
