Description

Technical Field

[0001] This application belongs to the technical field of atomizers, and particularly relates to an atomizer and an electronic atomization device. Background Art

[0002] An aerosol refers to a colloidal dispersion system composed of solid or liquid particles suspended in a gas medium. Since an aerosol can be absorbed by the human body through the respiratory system, an aerosol can be generated by heating an aerosol matrix with an atomizer. In some existing atomizers, when assembling the nozzle housing, the nozzle housing will pull the sealing ring inside the atomizer during the installation process, resulting in the sealing ring being skewed and affecting the sealing effect of the sealing ring. Utility Model Content

[0003] The purpose of the embodiments of this application is to provide an atomizer and an electronic atomization device to solve the technical problem that the sealing performance of the sealing ring of the nozzle housing of the atomizer is affected during assembly in the prior art.

[0004] To achieve the above purpose, the technical solution adopted in this application is:

[0005] In the first aspect of this application, an atomizer is provided, which includes a nozzle housing, an aerosol chamber, a frame body, and an atomization core. Among them, the nozzle housing includes a nozzle end and a lower cylinder body. The nozzle end is connected to the lower cylinder body. The aerosol chamber and the frame body are respectively arranged in the nozzle end and the lower cylinder body, and the atomization core is installed on the frame body. The atomizer further includes a sealing member arranged between the frame body and the aerosol chamber. One end of the lower cylinder body close to the nozzle end is in sealing cooperation with the sealing member, and an avoidance structure is formed on the inner side surface of the lower cylinder body. The avoidance structure is used to avoid the sealing member when installing the nozzle housing on the frame body.

[0006] In some implementation manners, the circumferential inner side surface of the lower cylinder body includes a first side surface and a second side surface. The first side surface is closer to the nozzle end than the second side surface. The first side surface is in sealing cooperation with the sealing member. In any longitudinal section of the atomizer passing through its central axis, the distance from the outer circumferential side surface of the sealing member to the central axis is less than the distance from the second side surface to the central axis to form an avoidance structure.

[0007] In some implementation manners, the nozzle end includes an inner cylinder body and an outer cylinder body. The inner cylinder body is arranged inside the outer cylinder body. One end of the inner cylinder body far from the frame body is circumferentially connected to one end of the outer cylinder body. The other end of the outer cylinder body is circumferentially connected to the lower cylinder body. An air intake hole is formed in the middle of the inner cylinder body. One end of the inner cylinder body close to the frame body is in sealing cooperation with the sealing member.

[0008] In some implementations, the seal includes a first seal portion and a second seal portion. The first seal portion is connected to the second seal portion. The first seal portion is disposed between the aerosol chamber and the frame body. An opening communicating with the aerosol chamber is provided on the first seal portion. The second seal portion is located between the first side surface and the frame body.

[0009] In some implementations, the atomizer further includes a bottom cover. The bottom cover is disposed at one end of the lower cylinder away from the mouthpiece end. The bottom cover and the lower cylinder are connected by a snap structure.

[0010] In some implementations, an aerosol flow channel adapted to the aerosol chamber is formed in the frame body. The atomization core is installed on the frame body and is located at the outlet end of the aerosol flow channel. An air intake hole is formed on the mouthpiece housing. An air flow channel communicating the atomization core and the air intake hole is formed between the frame body and the mouthpiece housing.

[0011] In some implementations, the frame body includes a top cover, an intermediate frame body, and a bottom frame. The top cover is close to the aerosol chamber and the top cover is supported on the bottom frame through the intermediate frame body. An aerosol flow channel is formed in the top cover.

[0012] In some implementations, the top cover includes an upper section, side sections, and a channel section. There are two side sections and the two side sections are respectively disposed on one side of the upper section away from the aerosol chamber. A seal is disposed between the upper section and the aerosol chamber. A jack and an inlet end of the aerosol flow channel are provided on the upper section. The jack is in sealing cooperation with the air intake hole of the mouthpiece housing through the seal.

[0013] There is a gap between the two side sections and the channel section is located between the two side sections. The channel section is connected to both side sections. An outlet end of the aerosol flow channel is formed on one side of the channel section close to the atomization core.

[0014] In some implementations, a liquid absorption cotton is disposed in the aerosol flow channel.

[0015] The second aspect of the present application provides an electronic atomization device, including a handheld rod and the atomizer in any of the above technical solutions. The handheld rod is connected to one end of the atomizer.

[0016] The beneficial effect of the present application is that: for the atomizer provided in this embodiment, by forming an avoidance structure on the inner side surface of the lower cylinder of the mouthpiece housing, during the process of assembling the mouthpiece housing to the frame body, at the beginning, the contact between the lower cylinder of the mouthpiece housing and the seal can be minimized through the avoidance structure. Until it is almost assembled in place, the inner side surface of the lower cylinder close to the mouthpiece end contacts the seal, thereby avoiding the situation of seal failure caused by the seal being pulled and skewed during the assembly of the mouthpiece housing in the related art.

[0047] Please refer to Figures 1 - 11 together, and now the atomizer 100 provided in the embodiment of this application will be described.

[0048] An atomizer 100 includes a mouthpiece housing 1, an aerosol chamber 2, a frame 3, and an atomization core 4.

[0049] Please refer to Figure 1 and Figure 2 , which are schematic diagrams of the appearance of the atomizer 100. Figure 1 and Figure 2 schematically show the mouthpiece housing 1. The mouthpiece housing 1 in this embodiment includes a mouthpiece end 11 and a lower cylinder 12, and the mouthpiece end 11 is connected to the lower cylinder 12. Preferably, the mouthpiece end 11 and the lower cylinder 12 are of an integrally formed structure. Please refer to Figure 4 , which is Figure 3 the cross-sectional view taken along the A-A direction in Figure 4 schematically shows that the aerosol chamber 2 is disposed inside the mouthpiece end 11, and the aerosol chamber 2 is used to accommodate aerosol. By disposing the aerosol chamber 2 inside the mouthpiece end 11, the space of the inner cavity of the mouthpiece end 11 can be fully utilized. Please refer to Figure 4, the frame body 3 is arranged inside the lower cylinder body 12. Among them, the atomization core 4 is installed on the frame body 3. The working principle of the atomization core 4 is to heat the heating wire or heating mesh in the atomization core 4 to the boiling point, and when the air flow passes through the atomization core 4, the aerosol formed by evaporation forms fog under the action of air flow condensation, and the fog flows out with the air flow.

[0050] In this embodiment, the aerosol chamber 2 is arranged at the mouthpiece end 11, and the frame body 3 supporting the atomization core 4 is arranged inside the lower cylinder body 12, which can make the structure of the atomizer 100 compact.

[0051] In this embodiment, the atomizer 100 further includes a sealing member 5 arranged between the frame body 3 and the aerosol chamber 2. Please refer to Figure 4 , which shows the sealing member 5. One end of the lower cylinder body 12 close to the mouthpiece end 11 can be hermetically fitted with the frame body 3 through the sealing member 5. By arranging the sealing member 5, the aerosol in the aerosol chamber 2 can be prevented from leaking.

[0052] Preferably, the sealing member 5 is made of silica gel.

[0053] In this embodiment, an avoidance structure is formed on the inner side surface of the lower cylinder body 12, and the avoidance structure is used to avoid the sealing member 5 when the mouthpiece housing 1 is installed on the frame body 3.

[0054] When assembling the atomizer 100, the aerosol chamber 2 is assembled inside the mouthpiece housing 1, the atomization core 4 is assembled inside the frame body 3, and the sealing member 5 is assembled on the frame body 3, and then the mouthpiece housing 1 is assembled on the frame body 3. If the avoidance structure is not arranged on the inner side surface of the lower cylinder body 12, when the mouthpiece housing 1 is inserted from the end of the frame body 3 where the sealing member 5 is arranged, the inner side wall of the lower cylinder body 12 will squeeze the sealing member 5, and there will be a frictional force between the sealing member 5 and the lower cylinder body 12. At the same time, due to the deep installation height and the inclination and shaking during the assembly process, the frictional force received by the sealing member 5 is large and the force is uneven, and the sealing member 5 is severely pulled, and even the sealing failure and liquid leakage may occur.

[0055] In this embodiment, by forming an avoidance structure on the inner side surface of the lower cylinder body 12, during the process of assembling the mouthpiece housing 1 onto the frame body 3, at the beginning, the contact between the lower cylinder body 12 of the mouthpiece housing 1 and the sealing member 5 can be minimized through the avoidance structure until it is almost assembled in place, and then the inner side surface of the lower cylinder body 12 close to the mouthpiece end 11 contacts the sealing member 5, avoiding the situation of sealing failure caused by the pulling and skewing of the sealing member 5 during the assembly of the mouthpiece housing 1 in the existing related technologies. In addition, when reducing the inclination and shaking amplitude of the mouthpiece housing 1 during the assembly process, by forming an avoidance structure on the inner side surface of the lower cylinder body 12, it can be realized that the sealing member 5 is in a state of no contact interference during the first stage of the assembly of the mouthpiece housing 1, and the sealing member 5 will only contact in the area where the mouthpiece housing 1 needs to be sealed.

[0056] Regarding the avoidance structure on the inner side surface of the lower cylinder body 12, in one embodiment, please refer to Figures 4 - 7 , the circumferential inner side surface of the lower cylinder body 12 includes a first side surface 121 and a second side surface 122. The first side surface 121 is closer to the nozzle end 11 than the second side surface 122, and the first side surface 121 is in sealing cooperation with the seal 5. Among them, in any longitudinal section of the atomizer 100 passing through its central axis, the distance from the outer circumferential side surface of the seal 5 to the central axis is less than the distance from the second side surface 122 to the central axis, so as to form an avoidance structure.

[0057] Please refer to Figure 4 , which shows the central axis L of the atomizer 100. The first side surface 121 is in sealing cooperation with the seal 5, that is, in any longitudinal section of the atomizer 100 passing through its central axis, the distance from the outer circumferential side surface of the seal 5 to the central axis L is greater than the distance from the first side surface 121 to the central axis L. When the seal 5 contacts the first side surface 121, the seal 5 undergoes elastic deformation under the extrusion of the first side surface 121 to achieve the sealing between the first side surface 121 and the seal 5.

[0058] In this embodiment, the distance from the outer circumferential side surface of the seal 5 to the central axis L is less than the distance from the second side surface 122 to the central axis L, that is, there is a gap between the outer circumferential side surface of the seal 5 and the second side surface 122. When assembling the nozzle housing 1 to the frame body 3, without contacting the second side surface 122 until the first side surface 121 contacts the seal 5, it is possible to reduce the tilting and shaking amplitude of the nozzle housing 1, avoiding the situation of seal failure caused by the pulling and skew of the seal 5 during the assembly of the nozzle housing 1 in the existing related technologies.

[0059] Please refer to Figure 4 and Figure 5 , in the longitudinal section of the atomizer 100 passing through its central axis, the distance from the second side surface 122 to the central axis L is greater than the distance from the first side surface 121 to the central axis L. In one example, the circumferential inner side surface of the lower cylinder body 12 further includes a third side surface 123, and the third side surface 123 is disposed between the first side surface 121 and the second side surface 122, and the third side surface 123 connects the first side surface 121 and the second side surface 122. Please refer to Figure 5 , along the direction from the second side surface 122 to the first side surface 121, the distance from the third side surface 123 to the central axis L gradually decreases, so as to facilitate the assembly of the nozzle housing 1 to the frame body 3. Please refer to Figure 6 and Figure 7 , Figure 6 is Figure 3 the schematic cross-sectional view taken along the line B-B in Figure 7 is Figure 6 the partial enlarged view at B in Figure 7The first side surface 121, the second side surface 122, and the third side surface 123 are also shown, and it is shown that the third side surface 123 connects the first side surface 121 and the second side surface 122.

[0060] Regarding the length of the third side surface 123 along the central axis L direction, since the third side surface 123 serves as a transition to connect the first side surface 121 and the second side surface 122, the length of the third side surface 123 along the central axis L direction can be set to be much smaller than the length of the second side surface 122 along the central axis L direction.

[0061] Regarding the first side surface 121, the first side surface 121 is preferably a straight cylinder, that is, on the same longitudinal section of the atomizer 100, the distance from the first side surface 121 to the central axis L is equal.

[0062] In the example where the circumferential inner side surface of the lower cylinder 12 further includes the third side surface 123, the second side surface 122 can be a straight cylinder, that is, on the same longitudinal section of the atomizer 100, the distance from the second side surface 122 to the central axis L is equal. Or, the second side surface 122 can also be set to be non-straight cylinder, for example, along the direction from the second side surface 122 to the first side surface 121, the distance from the second side surface 122 to the central axis L gradually decreases.

[0063] In one example, the circumferential inner side surface of the lower cylinder 12 may only include the first side surface 121 and the second side surface 122. At this time, the second side surface 122 can be set to be non-straight cylinder, that is, along the direction from the second side surface 122 to the first side surface 121, the distance from the second side surface 122 to the central axis L gradually decreases.

[0064] In this embodiment, by setting the distance from the outer circumferential side surface of the seal 5 to the central axis L to be less than the distance from the second side surface 122 to the central axis L to form an avoidance structure, during the process of assembling the nozzle housing 1 onto the frame body 3, it can be realized that at the beginning, the contact between the lower cylinder 12 of the nozzle housing 1 and the seal 5 can be minimized as much as possible. At the same time, the structure of the avoidance structure provided in this embodiment is simple and convenient for processing.

[0065] In order to avoid the second side surface 122 contacting the seal 5 as much as possible during the process of assembling the nozzle housing 1 onto the frame body 3, in the longitudinal cross-section of the atomizer 100, it is preferably that the difference between the distance from the outer circumferential side surface of the seal 5 to the central axis L and the distance from the second side surface 122 to the central axis L is as large as possible. However, considering that the outer circumferential side surface of the lower cylinder 12 is usually also set to be a straight cylinder for aesthetic reasons, therefore, the difference between the distance from the outer circumferential side surface of the seal 5 to the central axis L and the distance from the second side surface 122 to the central axis L should also be reasonably set to avoid the lower cylinder 12 affecting the strength of the atomizer 100 due to too small a thickness. Of course, in one example, it can be set as follows: a step is formed between the outer circumferential side surface of the nozzle end 11 and the outer circumferential side surface of the lower cylinder 12, that is, the distance from the outer circumferential side surface of the lower cylinder 12 to the central axis L is increased, so that when the difference between the distance from the outer circumferential side surface of the seal 5 to the central axis L and the distance from the second side surface 122 to the central axis L can be increased, the thickness of the lower cylinder 12 is not reduced, and the lower cylinder 12 is prevented from affecting the strength of the atomizer 100 due to too small a thickness.

[0066] Regarding the specific structure of the seal 5, in one embodiment, please refer to Figure 4 and Figure 8 , the seal 5 includes a first seal portion 51 and a second seal portion 52. The first seal portion 51 is connected to the second seal portion 52. Preferably, the first seal portion 51 and the second seal portion 52 are integrally formed. The first seal portion 51 is disposed between the aerosol chamber 2 and the frame body 3. An opening 511 communicating with the aerosol chamber 2 is provided on the first seal portion 51. The second seal portion 52 is located between the first side surface 121 and the frame body 3.

[0067] The sealing between the first side surface 121 and the frame body 3 can be achieved through the second seal portion 52, that is, the sealing between the nozzle housing 1 and the frame body 3 is achieved. The sealing between the frame body 3 and the aerosol chamber 2 is achieved through the first seal portion 51, so that the aerosol in the aerosol chamber 2 flows through the opening 511 into the atomization core 4 in the frame body 3.

[0068] The structure of the seal 5 provided in this embodiment can well achieve the sealing function to achieve the effect of preventing liquid leakage.

[0069] Regarding the specific structure of the nozzle end 11, in one embodiment, please refer to Figure 4 , the nozzle end 11 includes an inner cylinder 111 and an outer cylinder 112. The inner cylinder 111 is disposed inside the outer cylinder 112. One end of the inner cylinder 111 away from the frame body 3 is circumferentially connected to one end of the outer cylinder 112. The other end of the outer cylinder 112 is circumferentially connected to the lower cylinder 12. An air inlet hole 113 is formed in the middle of the inner cylinder 111. One end of the inner cylinder 111 close to the frame body 3 is in sealing cooperation with the seal 5.

[0070] Please refer to Figure 9 , which shows the aerosol chamber 2. The shape of the aerosol chamber 2 matches the shape of the cavity between the inner cylinder 111 and the outer cylinder 112. By arranging the aerosol chamber 2 inside the nozzle end 11, the space inside the nozzle end 11 can be fully utilized to reduce the volume of the atomizer 100.

[0071] The seal 5 further includes a third seal portion 53. Please refer to Figure 4 , which shows the third seal portion 53. The third seal portion 53 is cylindrical and is connected to the first seal portion 51. One end of the inner cylinder 111 is inserted into the third seal portion 53 to achieve a sealed fit between the inner cylinder 111 and the third seal portion 53.

[0072] Please refer to Figure 1 and Figure 2 , in one embodiment, the atomizer further includes a bottom cover 6. The bottom cover 6 is arranged at one end of the lower cylinder 12 away from the nozzle end 11, and the bottom cover 6 is connected to the snap structure 9 of the lower cylinder 12.

[0073] The connection between the bottom cover 6 and the lower cylinder 12 forms a cavity for installing components such as the mounting frame 3 inside the nozzle housing 1. In addition, in this embodiment, the snap connection between the bottom cover 6 and the lower cylinder 12 facilitates the assembly and disassembly of the bottom cover 6 and the lower cylinder 12.

[0074] Specifically, the bottom cover 6 includes a bottom plate and a circumferential side plate. The bottom plate is connected to the circumferential side plate in the circumferential direction. The bottom plate is arranged at one end of the lower cylinder 12, and the circumferential side plate is sleeved on the lower cylinder 12. The circumferential side plate is connected to the lower cylinder 12 through the snap structure 9.

[0075] Regarding the snap structure 9, in one example, elastic snaps are provided on the lower cylinder 12, and snap holes are provided on the circumferential side plate of the bottom cover 6. The bottom cover 6 is snap-connected to the lower cylinder 12 by inserting the elastic snaps into the snap holes.

[0076] Regarding the specific structure of the frame 3, in one embodiment, an aerosol flow channel 34 that cooperates with the aerosol chamber 2 is formed inside the frame 3. The atomization core 4 is installed on the frame 3 and is located at the outlet end of the aerosol flow channel 34; an air inlet hole 113 is formed on the nozzle housing 1, and an air flow channel that communicates the atomization core 4 and the air inlet hole 113 is formed between the frame 3 and the nozzle housing 1.

[0077] The aerosol in the aerosol chamber 2 flows to the atomization core 4 through the aerosol flow channel 34. When the heating wire or heating mesh of the atomization core 4 is in a heated state, the liquid aerosol matrix can be heated to the boiling point. When the air flow passes through the atomization core 4, the aerosol formed by evaporation forms a mist under the action of air flow condensation. The mist follows the air flow to the air flow channel and is finally discharged through the air inlet hole 113.

[0078] Please refer to Figure 2 and Figure 4 , an electrode 8 is inserted into the bottom cover 6, the electrode 8 is connected to the atomization core 4, the electrode 8 is limited in the frame body 3, and the power supply is connected through the electrode 8 to supply power to the atomization core 4, so that the heating wire or heating mesh of the atomization core 4 can be in a heating state.

[0080] Please refer to Figure 4 , the top cover 31 is in sealing cooperation with the aerosol chamber 2 through a seal 5, the bottom frame 33 is supported on the bottom cover 6, and the top cover 31 is supported on the bottom frame 33 through the intermediate frame body 32. In this embodiment, the frame body 3 is provided to include a top cover 31, an intermediate frame body 32 and a bottom frame 33, which is convenient for the assembly between the frame body 3, the atomization core 4 and the electrode 8.

[0081] In this embodiment, preferably, the bottom frame 33 is detachably connected to the top cover 31.

Specifically, elastic snaps are provided on the top cover 31, snap holes are provided on the bottom frame 33, and the elastic snaps on the top cover 31 are inserted into the snap holes on the bottom frame 33 to achieve the snap connection between the bottom frame 33 and the top cover 31.

[0082] In one example, the electrode 8 is limited between the intermediate frame body 32 and the bottom frame 33.

[0083] Regarding the specific structure of the top cover 31, please refer to Figure 10 and Figure 11 , in one embodiment, the top cover 31 includes an upper section 311, side sections 312 and a channel section 313. There are two side sections 312, and the two side sections 312 are respectively arranged on one side of the upper section 311 away from the aerosol chamber 2. A seal 5 is arranged between the upper section 311 and the aerosol chamber 2. A jack 3111 and an inlet end 341 of the aerosol flow channel 34 are arranged on the upper section 311.
