Description

Technical Field

[0001] The present application relates to the technical field of electronic atomization devices, and in particular to an atomizer and an electronic atomization device. Background Art

[0002] One of the core components of the electronic atomization device is the heating atomization module. Commonly used heating atomization modules are divided into ceramic heating atomization modules and cotton core heating atomization modules.

[0003] Compared with ceramic heating atomization modules and cotton core heating atomization modules, in the MEMS (Micro-Electro-Mechanical system) heating atomization module solution, the MEMS atomization core is a sheet structure with the advantages of small size, light weight, low power consumption, high reliability, high sensitivity, etc. It has high manufacturing precision and high product quality stability, which is conducive to the modular design of electronic atomization devices.

[0004] However, the MEMS atomizer core is generally in sheet form because its material is brittle and cannot be bent. In order to fully mix the air with the aerosol generated by the MEMS atomizer core, the MEMS atomizer core needs to be arranged horizontally in the airway. The air enters perpendicular to the MEMS atomizer core, and then mixes with the aerosol and bends around the MEMS atomizer core before being sucked out upward. Due to the many bends in the airway, the taste is distorted and the amount of aerosol is lost. For electronic atomizer devices using other sheet-shaped atomizer cores, there is also a similar problem of many bends in the airway affecting the taste.

[0005] In view of this, it is urgent to optimize the airway of the atomizer with a sheet-shaped atomization core to improve the taste of the electronic atomization device. Summary of the invention

[0006] The purpose of the present application is to provide an atomizer and an electronic atomization device. The airway layout of the atomizer is suitable for a sheet-like atomization core, such as a MEMS atomization chip.

The first airway section of the atomizer is the airway section where the inhaled air circulates. The airflow can rush to the vertically placed atomizer chip through the inclined terminal airway segment, and can take away the aerosol generated by the atomizer chip heating the e-liquid. The aerosol then mixed with the air can flow along the straight second airway section to the cigarette holder. The aerosol flows in the atomizer without turning, and the heat is more concentrated, which can maintain a better taste.

[0036] In order to enable those skilled in the art to better understand the solution of this application, the following further detailed description of this application will be given in conjunction with the drawings and specific embodiments.

[0037] The orientation words such as up, down, top, and bottom involved in this article are based on Figures 1 to 6 the position relationship of the components in the figure or between the components, and the inner in the orientation words refers to the side relatively close to the axial center of the atomizer, and the outer refers to the side relatively far from the axial center of the atomizer; the upstream and downstream in this article are defined based on the gas flow direction; the foregoing limitations are only for the convenience of understanding and describing the technical solution and do not constitute a limitation to the protection scope.

[0038] Please refer to Figure 1 and Figure 2 , Figure 1 It is a schematic cross-sectional view of the atomizer provided by the embodiment of this application at an angle; Figure 2 is Figure 1 a simple schematic diagram of the first airway section and the second airway section in Figure 2 In

[0039] Figure 1 and Figure 2The hollow arrows in the figure indicate the flow direction of the gas (including air and aerosol) in the atomizer, and the solid arrows indicate the oil suction path of the atomizer.

[0040] The atomizer provided in this embodiment can be used for an electronic atomization device, the atomizer has an airway, and the airway includes a first airway segment 1a and a second airway segment 1b that are interconnected. The first airway segment 1a is located below the second airway segment 1b, the first airway segment 1a has an air inlet, and the second airway segment 1b has an air outlet, that is, the gas enters from the first airway segment 1a, flows into the second airway segment 1b along the first airway segment 1a, and then flows out from the second airway segment 1b. The end where the air outlet of the second airway segment 1b is located is the mouthpiece end. When in use, the user inhales at the mouthpiece end.

[0041] The extension direction of the second airway section 1b is consistent with the axis of the atomizer. In other words, the second airway section 1b is a straight-through form, or the second airway section 1b is a linear structure without a bend. Figure 1 For the orientation shown, the axial direction of the atomizer is the up-and-down direction in the figure, which can be understood as the length direction of the atomizer as a whole.

[0042] The first airway segment 1 a includes a terminal airway segment 13 a adjacent to the second airway segment 1 b , and the terminal airway segment 13 a is arranged obliquely relative to the second airway segment 1 b .

[0043] The atomizer includes a sheet-shaped atomizer chip 20, which is roughly parallel to the axial direction of the second airway segment 1b. When the atomizer is in use, the plane of the atomizer chip 20 is parallel to the vertical direction, which can be understood as the atomizer chip 20 being placed vertically; the atomizer chip 20 is located at one end of the second airway segment 1b adjacent to the terminal airway segment 13a, and is configured so that the airflow flowing out of the terminal airway segment 13a can flow to the atomizer chip 20. In other words, the inclined setting of the terminal airway segment 13a is to guide the airflow flowing in from the air inlet to flow toward the atomizer chip 20, and the inclined setting of the terminal airway segment 13a relative to the second airway segment 1b plays a role in diverting the airflow.

[0044] After adopting the above scheme, the first airway section 1a of the atomizer is the airway section for the inhaled air to circulate. The airflow can rush to the vertically placed atomizer chip 20 through the inclined terminal airway segment 13a, and can take away the aerosol generated by the atomizer chip 20 heating the e-liquid. The aerosol is then formed and can flow along the straight second airway section 1b to the cigarette holder. The aerosol flows in the atomizer without turning, and the heat is more concentrated, which can maintain a better taste. At the same time, the aerosol flows in the straight second airway section 1b, with less loss, which is also conducive to improving the taste.

[0045] In one achievable manner, the atomizer chip 20 is disposed in the second airway segment 1b on the extension line of the terminal airway segment 13a along the gas flow direction, so that the airflow flowing out of the terminal airway segment 13a can directly rush to the atomizer chip 20, which is more conducive to improving the taste. In a specific implementation, the angle between the axis of the terminal airway segment 13a of the first airway segment 1a and the axis of the second airway segment 1b is α, such as Figure 2 It is indicated that the size of the angle α affects the amount of gas flowing out of the terminal airway segment 13a and rushing toward the atomization chip 20, and accordingly affects the amount of aerosol that can be carried away by the airflow, and has an impact on the aerosol concentration. When actually setting, the angle α can be set in combination with the specific structural parameters of the first airway segment 1a and the second airway segment 1b and needs.

[0046] Exemplarily, the angle α between the axis of the terminal airway segment 13a and the axis of the second airway segment 1b may be in the range of 20° to 70°, specifically 40°, 45°, 50°, etc.

[0047] In this embodiment, the first airway segment 1a further includes a head airway segment 11a and an intermediate airway segment 12a, the head airway segment 11a has an air inlet, the head airway segment 11a is connected to the terminal airway segment 13a through the intermediate airway segment 12a, and the intermediate airway segment 12a has at least one bend. The air flowing in from the air inlet flows into the terminal airway segment 13a after passing through the head airway segment 11a and the intermediate airway segment 12a, and the intermediate airway segment 12a has at least one bend, so that the smoke oil or condensate at the atomizer chip 20 can be prevented from dripping directly into the air inlet and leaking out.

[0048] In a specific implementation, the extension direction of the first airway segment 11a can be consistent with the extension direction of the second airway segment 1b. For example, the axis of the first airway segment 11a can be parallel to or colinear with the axis of the second airway segment 1b. In this way, based on the inclination of the terminal airway segment 13a relative to the second airway segment 1b, the middle airway segment 12a has at least two bending portions, that is, the middle airway segment 12a is arranged around a bend.

[0049] In one achievable manner, the atomizer further comprises a liquid guiding member, and the liquid guiding member is arranged on a side of the atomization chip facing away from the second airway segment 1 b.

[0050] The liquid guide member may include a first liquid guide member 30 and a second liquid guide member 40, which are sequentially arranged on a side of the atomizer chip 20 facing away from the second airway segment 1b. Specifically, the first liquid guide member 30 is in close contact with the atomizer chip 20, and the second liquid guide member 40 is in contact with the first liquid guide member 30; Figure 1 In the shown orientation, the atomization chip 20, the first liquid guiding member 30 and the second liquid guiding member 40 are arranged in the radial direction of the atomizer.

[0051] The first liquid guiding member 30 and the second liquid guiding member 40 may be made of porous media or cotton.

[0052] The atomizer has an oil tank 1c for storing tobacco oil. The oil outlet of the oil tank 1c corresponds to at least a portion of the position of the liquid guide member. The tobacco oil in the oil tank 1c can be guided to the atomizer chip 20 through the liquid guide member.

[0053] On the basis that the liquid guiding member is provided with the first liquid guiding member 30 and the second liquid guiding member 40, the oil outlet of the oil tank 1c can correspond to the position of the second liquid guiding member 40, the tobacco oil in the oil tank 1c can penetrate into the second liquid guiding member 40, and then be guided to the atomization chip 20 through the first liquid guiding member 30. The atomization chip 20 can turn on the heating circuit through control instructions to heat the tobacco oil to generate aerosol, which is mixed with the inflowing air and then sucked out.

[0054] On the basis of the above, the middle airway segment 12a of the first airway segment 1a can be provided with a bending structure as follows: along the gas flow direction, the upstream of the middle airway segment 12a bends in a direction away from the liquid guide member, and the downstream of the middle airway segment 12a bends in a direction close to the atomizer chip 20. In this way, the gas flow in the first airway segment 1a is relatively far away from the side where the liquid guide member is located, which can effectively prevent the smoke oil from leaking to the first airway segment 1a; at the same time, the bent first airway segment 1a can also prevent the condensed oil from falling directly to the position of the air inlet of the atomizer, avoiding affecting the air intake.

[0055] by Figure 1 and Figure 2 In the orientation shown, the first liquid guiding member 30 and the second liquid guiding member 40 are located on the right side of the atomizer chip 20. The gas of the head end airway segment 11a of the first airway segment 1a flows out and enters the middle airway segment 12a. In the middle airway segment 12a, the gas first turns to the left, then flows upward, and then turns to the right (i.e., the direction close to the atomizer chip 20) and enters the terminal airway segment 13a. After being inclinedly guided by the terminal airway segment 13a, the gas flows toward the atomizer chip 20 to take away the aerosol generated by the atomizer chip 20 heating the e-liquid.

[0056] Figure 2 In the example shown, the middle airway segment 12a is roughly a U-shaped structure with its opening facing the right side. In other implementations, the middle airway segment 12a of the first airway segment 1a can be other curved structures, not limited to the scheme shown in the figure, for example, it can be a serpentine curve or a spiral curve.

[0057] It should be pointed out here that, since the first airway segment 1a is the flow airway of air, the winding setting of the first airway segment 1a will not cause aerosol loss and will not affect the taste.

[0058] Please refer to Figures 3 to 6 , Figure 3 An exploded view of an atomizer provided in an embodiment of the present application; Figure 4 A schematic cross-sectional view of the atomizer provided in an embodiment of the present application at another angle; Figure 5 It is a structural schematic diagram of a bracket assembly in a specific embodiment; Figure 6 It is a structural schematic diagram of a base assembly in a specific embodiment.

[0059] In this embodiment, the atomizer includes a smoke pipe 10 , a support assembly 50 and a base assembly 60 .

[0060] The smoke tube 10 comprises an outer tube 101 and an inner tube 102, the outer tube 101 is sleeved on the outer side of the inner tube 102, the upper end of the inner tube 102 forms an air outlet of the second airway segment 1b, and the tube cavity of the inner tube 102 forms at least a part of the second airway segment 1b; the smoke tube 10 can be an integrally formed structure, the upper end of the smoke tube 10 is a flat structure, the upper end of the outer tube 101 and the upper end of the inner tube 102 are closed, and only have an air outlet, and the upper end of the smoke tube 10 forms a mouthpiece, and the user can inhale through the mouthpiece.

[0061] The bracket assembly 50 includes a bracket 51 , which is installed in the outer tube 101 and encloses the outer tube 101 and the inner tube 102 to form the aforementioned oil tank 1 c ; the atomization chip 20 can be installed in the bracket 51 .

[0062] The bracket assembly 50 may also include a first seal 52 and a second seal 53. The lower end of the inner tube 102 is specifically inserted into the bracket 51. The bracket 51 and the inner tube 102 are sealed by the first seal 52, and the bracket 51 and the outer tube 101 are sealed by the second seal 53. Specifically, the outer peripheral wall of the bracket 51 and the inner peripheral wall of the outer tube 101 are sealed by the second seal 53.

[0063] Specifically, the top wall surface of the bracket 51, the inner tube wall of the outer tube 101 and the outer tube wall of the inner tube 102 enclose the aforementioned oil tank 1c, so that the oil tank 1c is arranged around the second airway section 1b.

[0064] The first seal 52 can prevent the smoke oil in the oil tank 1c from leaking into the airway through the inner tube 102 and the bracket 51 , and the second seal 53 can prevent the smoke oil in the oil tank 1c from leaking through the bracket 51 and the outer tube 101 .

[0065] In the specific configuration, the bracket 51 is formed with an oil inlet connected to the oil tank 1c on one side close to the second liquid guide 40, so that the smoke oil in the oil tank 1c can penetrate into the second liquid guide 40. Figure 1 shown.

[0066] The base assembly 60 includes a base 61, which is encapsulated at the bottom of the smoke pipe 10, at least a portion of the base 61 is inserted into the bottom end of the outer tube 101, and at least a portion of the base 61 is also inserted into the bracket 51, and a first airway segment 1a and a portion of the second airway segment 1b are formed between the bracket 51 and the base 61. That is, a portion of the wall portion forming the first airway segment 1a is arranged on the base 61, and the other portion is arranged on the bracket 51, and the wall portion of the portion of the second airway segment 1b is also composed of a partial structure of the base 61 and a partial structure of the bracket 51. Obviously, the portion of the second airway segment 1b formed between the bracket 51 and the base 61 is connected to the tube cavity of the inner tube 102.

[0067] In a specific configuration, the head end airway segment 11 a and the middle airway segment 12 a of the first airway segment 1 a may be formed on the base 61 , and the terminal airway segment 13 a may be formed on the bracket 51 .

[0068] In the specific configuration, an installation space for installing the atomization chip 20 and the liquid guide member (including the first liquid guide member 30 and the second liquid guide member 40) is formed between the bracket 51 and the base 61, and the aforementioned installation space can also be formed only on the bracket 51, such as Figure 1 As shown, part of the wall surface of the first liquid guide member 30 also forms part of the wall portion of the second airway segment 1 b , and the atomizer chip 20 is arranged on this part of the wall surface of the first liquid guide member 30 to facilitate the atomizer chip 20 to heat the e-liquid carried on the first liquid guide member 30 .

[0069] In order to prevent the smoke oil from leaking into the first air duct segment 1a or the second air duct segment 1b without heating, the bracket assembly 50 also includes a third sealing member 54, and the outer periphery of the first liquid guiding member 30 and / or the second liquid guiding member 40 is sealed with the bracket 51 and / or the base 61 through the third sealing member 54. In other words, when the installation space is formed on the bracket 51, the outer periphery of the first liquid guiding member 30 and / or the second liquid guiding member 40 is sealed with 51 through the third sealing member 54, and when the installation space is formed between the bracket 51 and the base 61, the outer periphery of the first liquid guiding member 30 and / or the second liquid guiding member 40 is sealed with the bracket 51 and the base 61 through the third sealing member 54.

[0070] In one practicable manner, at least one of the first seal 52 , the second seal 53 and the third seal 54 may be integrally formed with the bracket 51 , which can simplify the number of parts, facilitate assembly, and help improve assembly efficiency.

[0071] In the illustrated example, the first seal 52 , the second seal 53 , and the third seal 54 are all integrally formed with the bracket 51 to form one component.

[0072] In other embodiments, only part of the first seal 52, the second seal 53 and the third seal 54 may be integrally formed with the bracket 51; the first seal 52 and the second seal 53 may also be integrally formed, and the third seal 54 and the second seal 53 may also be integrally formed without interference in assembly.

[0073] In the specific setting, a fourth seal 55 is provided between the base 61 and the outer tube 101 to prevent the smoke oil or condensate from leaking from between the base 61 and the outer tube 101 to the outside of the atomizer and affecting the control device of the electronic atomization device. It can be understood that the fourth seal 55 is closer to the bottom of the atomizer relative to the second seal 53.

[0074] In the illustrated example, the fourth sealing member 55 is integrally formed with the bracket 51 to further simplify the number of parts and facilitate assembly; in other embodiments, the fourth sealing member 55 may be integrally formed with the base 61 .

[0075] The above-mentioned sealing components can be made of sealing silicone or the like, and can be integrally formed with the bracket 51 or the base 61 by injection molding.

[0076] In this embodiment, the base assembly 60 further includes a spring 62, which is electrically connected to the atomizer chip 20. One end of the spring 62 can be fixed to the base 61, and the other end is elastically in contact with the atomizer chip 20 and electrically connected. In specific settings, the spring 62 and the base 61 can be integrally formed to simplify the number of parts and facilitate assembly. The spring 62 and the base 61 can also be integrally formed by injection molding.

[0077] In this embodiment, the outer peripheral wall of the base 61 has an airway groove 611, and the airway groove 611 is used to connect the oil tank 1c and the outside world. The outside world here is relative to the oil tank 1c. Specifically, the airway groove 611 has a first slot 611a and a second slot 611b. The airway groove 611 is connected to the outside world through the first slot 611a, and is connected to the oil tank 1c through the second slot 611b. In this way, the airway groove 611 forms a ventilation channel to balance the air pressure in the oil tank 1c, which is beneficial to the smoothness of the oil supply.

[0078] In a specific configuration, the first notch 611a of the airway groove 611 may be communicated with the air inlet of the first airway segment 1a.

[0079] When setting specific Figure 6 As shown, the airway groove 611 can be arranged along the outer peripheral wall of the base 61, and the specific structural form of the airway groove 611 is not limited, as long as it can connect the outside and the oil tank 1c to ensure the reliability of the atomizer.

[0080] In a specific implementation, in order to prevent the oil in the oil tank 1c from leaking out through the airway groove 611 during ventilation, a ventilation check valve 511 is provided on the bracket 51. The ventilation check valve 511 is provided between the airway groove 611 and the oil tank 1c and is used to unidirectionally guide the passage from the airway groove 611 to the oil tank 1c. The ventilation check valve 511 can be integrally formed with the bracket 51 to facilitate assembly.

[0081] The peripheral wall of the base 61 forming the airway groove 611 is inserted into the bracket 51, and a ventilation channel is formed between the airway groove 611 and the inner peripheral wall of the bracket 51, and the second notch 611b of the airway groove 611 is close to the top wall of the bracket 51. The top wall of the bracket 51 is provided with a valve plate of a cantilever structure, one end of which is connected to the bracket 51 and the other end is suspended, and the top wall of the bracket 51 has a hole or a groove structure connected to the second notch 611b of the airway groove 611, and the valve plate can cover the hole or groove structure, and the valve plate and the corresponding hole or groove structure form a ventilation check valve 511, and the valve plate can be deformed in one direction to guide the passage from the airway groove 611 to the oil tank 1c in one direction.

[0082] Combination Figure 4 and Figure 5 The valve plate of the ventilation check valve 511 is subjected to the downward force of the air pressure in the oil tank 1c and the upward force of the air pressure in the airway groove 611. When the pressure difference force applied to the valve plate is downward, that is, the air pressure in the oil tank 1c is greater than the air pressure in the airway groove 611, the valve plate closes the second slot 611b under the action of the pressure difference force, so that the passage between the airway groove 611 and the oil tank 1c is cut off. When the pressure difference force applied to the valve plate is upward, that is, the air pressure in the oil tank 1c is less than the air pressure in the airway groove 611, the valve plate tilts upward under the action of the pressure difference force, and can connect the oil tank 1c and the airway groove 611 to achieve ventilation.

[0083] In the illustrated example, the airway groove 611 has two second notches 611b connected to the oil tank 1c. Accordingly, two ventilation check valves 511 are provided on the bracket 51, respectively cooperating with the two second notches 611b. In other embodiments, the second notches 611b connecting the airway groove 611 and the oil tank 1c can be provided as needed, and can be only one or three, etc., and the number is not limited here.

[0084] In this embodiment, the atomizer chip 20 of the atomizer may specifically be a MEMS atomizer chip to improve the manufacturing accuracy and quality stability of the product.
