Description

Technical Field

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

[0002] An atomizer is a common electronic product used to heat and atomize an aerosol-forming matrix to form an aerosol. Among them, the airway serves as a channel for discharging the aerosol and supplying it to the user.

[0003] In the related art of the aerosol flowing in the airway, due to the Coanda effect (also known as the wall attachment effect), most of the aerosol in the airway has the phenomenon of transmitting along the airway wall surface. The airway wall has an impact on the aerosol in terms of frictional resistance and low temperature, which will cause a large number of aerosol particles to condense and adhere to the airway wall surface. This not only affects the performance and lifespan of the atomizer, but also is easily sucked into the mouth by the user, bringing a bad experience to the user. Utility Model Content

[0052] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0053] In the atomizer in the related art, the applicant found that during the process of the air flow passing through the atomization core 6 to form an aerosol, since the air flow necessarily needs to pass through a certain distance, this causes the air flow to be rectified in this section of the air duct, and an aerosol that tends to flow along the surface of the flow channel is formed. This further causes the aerosol to easily flow along the wall surface in the last section of the exhaust air duct.

[0054] As Figures 1 - 5 shown, an embodiment of the present application provides an atomizer, including a main body and an atomization core 6; a liquid storage chamber 101, an atomization air duct 102, a shunt air duct 103 and an exhaust air duct 104 are provided inside the main body. The liquid storage chamber 101 is used to store the aerosol formation matrix, and an air inlet 106 is provided on the main body. The atomization air duct 102 and the shunt air duct 103 are connected in parallel between the air inlet 106 and the exhaust air duct 104, that is, the atomization air duct 102 is connected between the air inlet 106 and the exhaust air duct 104, and at the same time the shunt air duct 103 is also connected between the air inlet 106 and the exhaust air duct 104; the atomization core 6 is arranged in the main body and has an atomization surface 601 exposed in the atomization air duct 102. The atomization core 6 can absorb the aerosol formation matrix and heat and atomize it on the atomization surface 601 to form an aerosol; wherein, the air flow from the shunt air duct 103 flows into the confluence of the atomization air duct 102, the shunt air duct 103 and the exhaust air duct 104 at least partially in a first direction parallel to the atomization surface, and the first direction intersects with the extending direction of the exhaust air duct 104.

[0055] The applicant has found that an air flow stagnation area is likely to form at the intersection of the atomization airway 102 and the exhaust airway 104. Coupled with the factor that the aerosol tends to adhere to the wall for transmission, the aerosol is likely to remain here to form eddies and condensate, especially the corner eddies formed at both sides of the atomization surface 601. In this application, through the suction action of the user, the air flow entering the atomizer not only passes through the atomization airway 102 to form an aerosol, but the air flow is split into two parts. One part of the air flow passes through the atomization airway 102 and passes through the atomization core to form an aerosol, and the other part of the air flow passes through the shunt airway 103. And the air flow from the shunt airway 103 at least partially flows into the intersection of the atomization airway 102, the shunt airway 103 and the exhaust airway 104 in the first direction, and the first direction is parallel to the atomization surface 601 and intersects with the extending direction of the exhaust airway 104. In this way, the air flow from the shunt airway 103 can carry out the aerosol in the air flow stagnation area at the intersection, and make this part of the aerosol flow into the exhaust airway 104 together with the aerosol in the atomization airway 102, preventing aerosol condensation at the intersection. At the same time, the air flow from the shunt airway 103 also disturbs the aerosol from the atomization airway 102, breaking the original flow state of the aerosol tending to adhere to the wall for transmission at the intersection, thereby preventing the aerosol from adhering to the wall for transmission in the exhaust airway 104, and further avoiding the phenomenon of aerosol condensation in the exhaust airway 104, solving the problem that aerosol condensation is likely to occur in the airway of the atomizer in the related art, realizing the improvement of the performance and life of the atomizer, and at the same time improving the user experience.

[0056] It should be noted that regarding the intersection of the atomization airway 102, the shunt airway 103 and the exhaust airway 104, due to the diffusivity of the air flow, the intersection may specifically refer to the entrance of the exhaust airway 104, or the area outside the exhaust airway 104 close to the entrance of the exhaust airway 104, or the position in the exhaust airway 104 close to the entrance of the exhaust airway 104. This application does not make specific limitations.

[0057] Moreover, in some types of atomizers, due to factors such as the limitation of the internal structure, the air flow path design will have a situation where the air flow passing surface of the airway changes suddenly. For example, at the connection between the atomization airway 102 and the exhaust airway 104, when the air flow encounters a sudden change in the air flow passing surface from small to large, an obvious reverse eddy will be generated near the entrance of the exhaust airway 104, as Figure 8 shown, causing part of the aerosol to be trapped in the eddy and unable to be transmitted to the outlet of the atomizer, which will not only reduce the aerosol concentration, but also increase the condensate on the airway wall. And for the atomizer provided in this application, since an additional air flow from the shunt airway 103 is introduced at the connection between the atomization airway 102 and the exhaust airway 104, the air flow of the shunt airway 103 impacts the aerosol at the intersection of the atomization airway 102, the shunt airway 103 and the exhaust airway 104, which can significantly reduce the reverse eddy area. In this regard, the problem of reduced aerosol concentration and increased condensate on the airway wall is also solved.

[0058] In addition, in order to ensure a smooth suction feeling for the user, the atomization airway 102 and the exhaust airway 104 are generally arranged opposite or substantially opposite in the air flow direction, or in other words, the extending directions of the atomization airway 102 and the exhaust airway 104 are almost the same. The atomization core 6 in this application can specifically be in the form of a planar atomization core, a columnar atomization core, etc. The figure shows an exemplary illustration where the atomization core 6 is a planar atomization core.

[0059] Regarding the relationship between the first direction and the extending direction of the exhaust airway 104, in some alternative embodiments, as Figures 4 - 5 shown, the first direction can be perpendicular to the extending direction of the exhaust airway 104, that is, the air flow of at least part of the shunt airway 103 is injected perpendicular to the flow direction of the aerosol; of course, it is also feasible that there is a small included angle between the first direction and the extending direction of the exhaust airway 104.

[0060] Regarding the relationship between the extending direction of the exhaust airway 104 and the atomization surface 601, the atomization surface 601 is inclined relative to the exhaust airway 104, as Figure 5 shown; in some other feasible embodiments, the atomization surface 601 can be parallel to the exhaust airway 104.

[0061] In some embodiments, the effective flow-through area of the outlet of the shunt airway 103 is smaller than the effective flow-through area of the inlet of the shunt airway 103. Specifically, it can be set that from the inlet of the shunt airway 103 to the outlet of the shunt airway 103, the effective flow-through area of the shunt airway 103 decreases step by step or tapers, or the effective flow-through area of the part of the shunt airway 103 close to the outlet decreases. The effective flow-through area in this application refers to the area actually participating in the flow when the air flow passes through the cross-sections of the inlet and the outlet.

[0062] With such a setting, a pressurized design can be formed at the outlet of the shunt airway 103, and the air flow is ejected at a high flow rate at the outlet of the shunt airway 103. In this way, a small amount of air flow in the shunt airway 103 can effectively impact the aerosol from the atomization airway 102, effectively affect and change the flow direction of the aerosol from the atomization airway 102, so as to achieve the purpose of using a small flow of air to affect the flow direction of the aerosol from the atomization airway 102.

[0063] In some embodiments, the effective flow-through volume of the shunt airway 103 is less than or equal to 30% of the effective flow-through volume of the air inlet 106. The effective flow-through volume in this application refers to the volume of the air flow passing through a certain cross-section within a certain period of time. The ratio of the effective flow-through volume of the shunt airway 103 to the effective flow-through volume of the air inlet 106 is used to reflect the proportion of the air flow passing through the air inlet 106 that enters the shunt airway 103 and the atomization airway 102 respectively.

[0064] With such a setting, most of the air flow entering the air inlet 106 enters the atomization airway 102, which can ensure sufficient air flow in the atomization airway 102, so as to ensure that the generation amount of aerosol in the atomization airway 102 can reach the expected level and obtain a better taste.

[0065] Regarding how the atomization airway 102 and the shunt airway 103 are separated and formed, in some embodiments, an air flow separator 5 is provided in the main body and is assembled and connected to the main body, such as Figure 6 As shown, the air flow separator 5 cooperates with the atomization core 6 to construct the atomization airway 102, and the air flow separator 5 cooperates with the main body to construct the shunt airway 103. That is, a part of the space between the air inlet 106 and the exhaust duct 104 is separated into the atomization airway 102 and the shunt airway 103 by the air flow separator 5. The air flow separator 5 can be a silica gel product.

[0066] With such a setting, by designing a structurally independent air flow separator 5 that can be assembled with the main body to form the atomization airway 102 and the shunt airway 103, this is beneficial to simplifying the structural design of the main body itself and facilitating the overall assembly of the atomizer.

[0067] Of course, in addition to the above-mentioned method of assembling the air flow separator 5 in the main body, it is also feasible to provide an integrally formed airway structure inside the main body as the atomization airway 102 and the shunt airway 103.

[0068] In a specific embodiment, such as Figure 6 As shown, the shunt airway 103 includes a first channel 1031 and a second channel; the first channel 1031 is opened on the air flow separator 5, the first channel 1031 is communicated with the air inlet 106 and extends in a direction away from the air inlet 106. The extending direction of the first channel 1031 can specifically be the same as the extending direction of the exhaust duct 104. The entrance of the first channel 1031 is the entrance of the shunt airway 103; the second channel is opened on the air flow separator 5, the second channel is communicated with the first channel 1031 and extends in a direction close to the exhaust duct 104. The exit of the second channel is the exit of the shunt airway 103. The first channel 1031 and the second channel can be grooves opened on the surface of the air flow separator 5 or hollow channels opened inside the air flow separator 5. For the convenience of understanding, when the atomizer is placed upright along the length direction, the first channel 1031 can be regarded as the vertical channel part, and the second channel can be regarded as the horizontal channel part.

[0069] With such a setting, by performing a special-shaped design on the air flow separator 5, a shunt airway 103 with a reversible air flow direction is formed, making full use of the limited space inside the main body to divert part of the air flow from the air inlet 106 to the connection between the exhaust duct 104 and the atomization airway 102.

[0070] In a preferred embodiment, the second channel is arranged to extend perpendicular to the extending direction of the exhaust passage 104 or in a plane satisfying the perpendicular condition.

[0071] With such an arrangement, when the airflow exits from the second channel of the shunt airway 103, its flowing direction is perpendicular to the flowing direction of the aerosol from the atomization airway 102. Under the same air flow rate, the airflow ejected in this way has a strong disturbing ability to the aerosol from the atomization airway 102 and will not affect the smooth feeling of the user's suction.

[0072] In another preferred embodiment, the second channel includes a main channel section 1032 and a branch channel section 1033; the main channel section 1032 is communicated with the first channel 1031; the branch channel section 1033 is communicated with the main channel section 1032 and is provided with a plurality of outlets communicated with the atomization airway 102, so that the shunt airway 103 forms a plurality of outlets.

[0073] With such an arrangement, the airflow of the shunt airway 103 is ejected in multiple directions to form impacts on the aerosol from the atomization channel at multiple angles, so that the aerosol is more fully disturbed before entering the exhaust passage 104, further enhancing the effect of preventing aerosol condensation in the exhaust passage 104.

[0074] On this basis, by arranging the branch channel section 1033 to be narrower than the main channel section 1032, the shunt airway 103 can form a pressurized airway.

[0075] Combined with the above embodiments, in order to make the pressurization effect of the shunt airway 103 obvious, the effective flow-through area of the first channel 1031 can be set to be larger than the effective flow-through area of the main channel section 1032 of the second channel, and the effective flow-through area of the main channel section 1032 of the second channel is larger than the effective flow-through area of the branch channel section 1033 of the second channel.

[0076] Furthermore, the outlets of at least two branch channel sections 1033 can be symmetrically arranged about the main channel section 1032 in the first direction, or the outlets of at least two shunt airways 103 are arranged opposite to the outlet of the atomization airway 102. In this way, while taking into account enhancing the disturbing effect on the aerosol, the feasibility of the design and manufacture of the airflow separator 5 is ensured to be strong.

[0077] In addition, the branch channel section 1033 can be arranged in a shape such as an arc or a straight line. When the branch channel section 1033 is designed as an arc and there are two symmetric branch channel sections 1033, the inner area surrounded by the branch channel section 1033 can be provided with the outlet of the atomization airway 102, which is beneficial to the compact and small structure of the airflow separator 5 and brings high feasibility to the structural design of the airflow separator 5.

[0078] In some alternative embodiments, the atomization surface 601 is arranged obliquely with respect to the exhaust passage 104; the outlet of at least one branch passage segment 1033 is an impact air port 1034, and the impact air port 1034 is directly opposite to the middle position on the side of the atomization surface 601 close to the exhaust passage 104, and the impact air port 1034 has a gradually expanding diversion surface 1035 provided on the side wall or an inclined diversion surface 1036 provided on the bottom wall, or both the gradually expanding diversion surface 1035 and the inclined diversion surface 1036 are provided, as Figure 7 shown, the gradually expanding diversion surface 1035 makes the impact air port 1034 in a flared shape.

[0079] With such a setting, the impact air port 1034 has an inclined diversion surface 1036 with respect to the exhaust passage 104, which is used to guide part of the air flow in the branch passage segment 1033 to impact the aerosol through the impact air port 1034, so as to reduce the horizontal component of the aerosol, reduce the contact between the aerosol in the atomization airway 102 and the inner wall of the exhaust passage 104 when entering the exhaust passage 104, and reduce the occurrence of the situation where the aerosol releases heat to form condensate; the gradually expanding diversion surface 1035 can increase the contact area between the air flow passing through the impact air port 1034 and the aerosol, and enhance the anti-wall-attaching flow effect of the air flow on the outermost aerosol.

[0080] In some other embodiments, the atomization airway 102 includes an atomization groove opened on the air flow partition 5, the atomization core 6 includes a heating part and crimping parts located on both sides of the heating part, that is to say, the atomization core 6 is a planar atomization core, the heating part is opposite to the atomization groove, and the crimping parts are attached to and connected with the air flow partition 5.

[0081] With such a setting, the atomization airway 102 is in the form of a groove on the air flow partition 5, so that the air flow partition 5 is easy to be adapted to the planar atomization core to construct the atomization airway 102; moreover, it also makes the assembly feasibility between the air flow partition 5 and the planar atomization core high.

[0082] In some alternative embodiments, a buffer space 105 is provided between the air inlet 106 and the air flow partition 5, and both the atomization airway 102 and the shunt airway 103 communicate with the buffer space 105, that is, there is a certain interval between the inlet of the atomization airway 102 and the inlet of the shunt airway 103 and the air inlet 106.

[0083] With such a setting, after the air flow enters the main body through the air inlet 106, the air flow passes through the buffer space 105 and then flows into the atomization airway 102 and the shunt airway 103 respectively. On the one hand, it can reduce the resistance of the air flow entering the atomization airway 102 and the shunt airway 103; on the other hand, the buffer space 105 provides a larger communication area, provides more feasible design positions for the inlet of the atomization airway 102 and the inlet of the shunt airway 103, and is beneficial to simplifying the structural design of the air flow partition 5.

[0084] In some embodiments, the main body has an assembled component structure, and the main body includes a housing 1, a hollow tube 2, a bracket 3, and a sealing plug 4; the housing 1 is in the shape of a hollow rod, and an assembly port is provided at the bottom of the housing 1; the hollow tube 2 is inserted into the housing 1, one end of the hollow tube 2 is located in the housing 1 and the other end communicates with the outside, so as to form an exhaust passage 104 in the hollow tube 2; the bracket 3 is assembled and connected to the housing 1 and the hollow tube 2 to construct a liquid storage chamber 101 between the hollow tube 2 and the housing 1; the sealing plug 4 is connected in the assembly port, and an air inlet 106 is provided in the sealing plug 4; wherein, an air flow separator 5 is connected between the bracket 3 and the sealing plug 4, a diversion air passage 103 is formed between the air flow separator 5 and the bracket 3, and the bracket 3 presses the atomization core 6 on the air flow separator 5 to form an atomization air passage 102 between the atomization core 6 and the air flow separator 5. With such a setting, the main body is assembled through the assembly connection between multiple components, which facilitates the assembly of the air flow separator 5 in the main body and is also beneficial to improving the feasibility of the atomizer provided in the present application in production and assembly.
