Description

Title of the invention: Atomization Device technical field

[0001] This publication relates to the field of atomization devices and, in particular, to an atomization device. Previous technique

[0002] An existing atomizing device comprises a main body and an atomizing core assembly, wherein at least a portion of the atomizing core assembly is located within a housing chamber defined by the main body. The atomizing core assembly defines an airway within it and is configured to generate an aerosol, allowing the aerosol to flow through the airway to the outside for inhalation by a user.

[0003] After prolonged use of the atomizing device, the atomized liquid initially contained in the atomizing core assembly will be gradually consumed. Therefore, it is generally necessary to add more atomized liquid to the atomizing device to prevent the atomizing core assembly from burning out. In the related art, when atomized liquid is added to the atomizing device, the high flow rate of the added atomized liquid can easily cause it to impact the atomizing core assembly, leading to leakage of the atomized liquid. Presentation of the invention

[0004] Embodiments of the invention aim to solve a technical problem whereby, in an atomizing device of the related art, an atomized liquid tends to impact an assembly of atomizing nuclei and cause leakage when the atomized liquid is added.

[0005] To solve the above technical problem, an atomizing device is proposed in the embodiments of the invention. The atomizing device comprises an atomizing core assembly, a sealing element, and a housing. The atomizing core assembly is configured to heat an atomized liquid. The housing defines a first injection hole for injecting the atomized liquid. The atomizing core assembly and the sealing element are connected to each other and are both located inside the housing. The sealing element is at least partially located between the atomizing core assembly and the first injection hole.

[0006] Compared to related art, the embodiments of the invention primarily have the following beneficial effects.

[0007] In the invention, the sealing element is located between the atomizing core assembly and the first injection hole. Therefore, when an atomized liquid is injected by a user into the atomizing device through the first injection hole using an infusion element, the atomized liquid flowing out of the infusion element cannot directly contact or impact the atomizing core assembly. Instead, the atomized liquid will first contact the sealing element and then gradually penetrate and flow into the atomizing core assembly. In summary, the atomizing device in this embodiment can prevent the atomized liquid from impacting the atomizing core assembly and causing leaks. Brief description of the drawings

Detailed description of the implementation methods

[0024] Unless otherwise defined, all technologies and scientific terms used in the invention have common meanings that can be understood by a person skilled in the art. All terms used in the invention are solely intended to illustrate specific embodiments but are not intended to limit the invention. The terms "comprising," "contains," "having," and all variations thereof are intended to cover non-exclusive inclusions. The terms "first," "second," etc., in the description and claims of the invention and in the accompanying drawings above are used to distinguish different objects but are not used to describe a specific order.

[0025] The term "embodyment," as used herein, means that specific features, structures, or characteristics described with reference to the accompanying drawings may be included in at least one embodiment of the invention. The expressions in the invention are not necessary to refer to the same embodiment and do not refer to an independent embodiment and an alternative embodiment that are exclusive of other embodiments. It can be explicitly and implicitly understood by those skilled in the art that the embodiments described in the invention can be combined with other embodiments.

[0026] To solve the problem described, with reference to [Fig. 1] to 3 and FIGS. 7 to 9, an atomization device 10 is provided in the embodiments. The The atomizing device 10 comprises an atomizing core assembly 300, a sealing element 200, and a housing 100. The atomizing core assembly 300 is configured to heat an atomized liquid. The housing 100 defines a first injection hole 120 for injecting the atomized liquid. The atomizing core assembly 300 and the sealing element 200 are connected to each other and are both located inside the housing 100. The sealing element 200 is at least partially located between the atomizing core assembly 300 and the first injection hole 120.

[0027] Since the sealing element 200 is located between the atomizing core assembly 300 and the first injection hole 120, by the process illustrated in [Fig.9], when a user uses an infusion element 20 to inject the atomized liquid into the atomizing device 10 through the first injection hole 120, the atomized liquid exiting the infusion element 20 will not directly come into contact with and impact the atomizing core assembly 300, but first comes into contact with the sealing element 200 and then gradually flows into the atomizing core assembly 300.

[0028] Therefore, the atomizing device 10 in this embodiment can avoid leaks caused by the impact of the atomized liquid on the atomizing core assembly 300.

[0029] Furthermore, if the sealing element 200 is in contact with an external side wall of the atomizing core assembly 300, the atomized liquid may take a long time to come into contact with the atomizing core assembly 300, resulting in a decrease in heating efficiency. In this embodiment, the sealing element 200 is at least partially located between the atomizing core assembly 300 and the first injection hole 120. An injection space 240 is defined between at least a portion of the sealing element 200 and the external side wall of the atomizing core assembly 300. The injection space 240 allows the flow of the atomized liquid. In this case, the injection space 240 can prevent the atomized liquid from impacting the atomized core assembly 300 while improving the speed at which the atomized liquid comes into contact with the atomization core assembly 300.

[0030] Furthermore, with reference to FIGS. 7 to 9, the sealing element 200 comprises a limiting portion 210 and a projecting portion 220 connected to each other. The injection space 240 is defined between the limiting portion 210 and the outer side wall of the atomizing core assembly 300.

[0031] The projecting portion 220 is located at one end of the limiting portion 210 near the first injection hole 120. The projecting portion 220 protrudes towards the external side wall of atomizing core assembly 300 and comes against the external side wall of atomizing core assembly 300.

[0032] During the injection of the atomized liquid into the atomizing device 10 in practical use, the atomized liquid can impact the sealing element 200, causing deformation of the sealing element 200, and thus, it is not possible to prevent the atomized liquid from impacting the atomizing core assembly 300. In this embodiment, by arranging the protruding part 220, the protruding part 220 can prevent deformation of the limiting part 210 by contacting the outer side wall of the atomizing core assembly 300 when the atomized liquid impacts the sealing element 200.

[0033] In addition, a thickness of the protruding part 220 is less than a thickness of the limiting part 210 to define a communication opening (not marked on the figure) in communication with the injection space 240. The communication opening allows the atomized liquid to flow into the injection space 240.

[0034] It can be understood that, in certain embodiments, when the sealing element 200 surrounds the side wall of the atomizing core assembly 300, or when a portion of the side wall of the atomizing core assembly 300 not covered by the sealing element 200 is covered by other components, the atomized liquid can only enter the injection space 240 through the communication opening and then enter the atomizing core assembly 300. In this case, it is also possible to prevent the atomized liquid from impacting the atomizing core assembly 300. When the atomized liquid is added, the infusion element 20 can be aligned with the communication opening to allow the atomized liquid to enter the injection space 240 through the communication opening, thus improving the injection efficiency of the atomized liquid.

[0035] Furthermore, with reference to [Fig.7] and [Fig.8], the width of the injection space 240 varies from 0.5 mm to 1 mm; and / or the thickness of the protruding part 220 varies from 1.1 mm to 1.5 mm, and the thickness of the limiting part 210 varies from 0.5 mm to 1 mm; and / or the injection space 240 gradually increases in width in a direction away from the protruding part 220; and / or the height of the first injection hole 120 is equal to the height of the injection space 240.

[0036] In [Fig.7], a vertical direction is the Z direction, and a horizontal direction is the Y direction.

[0037] When the width of the injection space 240 is between 0.5 mm and 1 mm, the atomized liquid can create a liquid flow gap phenomenon within the injection space 240. The liquid flow is caused by a pure pressure difference, i.e., pressure differential flow. This prevents ineffective obstruction from the impact of the atomized liquid on the core assembly. atomizing 300 due to an injection space 240 that is too large and also allows the atomized liquid to rise along the injection space 240, facilitating the entry of the atomized liquid inside the atomizing core assembly 300, along the injection space 240, through the second injection hole 311 on the outer side wall of the atomizing core assembly 300.

[0038] The thickness of the protruding portion 220 must be greater than the thickness of the limiting portion 210, so that when the protruding portion 220 abuts the outer side wall of the atomizing core assembly 300, the injection space 240 can be defined between the limiting portion 210 and the outer side wall of the atomizing core assembly 300. The difference between the thickness of the protruding portion 220 and the thickness of the limiting portion 210 determines the size of the communication opening, i.e., determines the speed at which the atomized liquid enters the injection space 240.Therefore, within the range of the thickness of the protruding part 220 and the thickness of the limiting part 210 in the invention, the atomized liquid can easily enter the injection space 240, and a liquid leakage can be avoided, the liquid leakage being caused by excessive impact applied to the atomizing core assembly 300 due to the injection of too large a quantity of atomized liquid at one time.

[0039] It can be understood that the width of the injection space 240 can be any one of 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm and 1 mm, or within a range formed by any two of 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm and 1 mm. The thickness of the protruding part can be any one of 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm and 1.5 mm, or within a range formed by any two of 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm and 1.5 mm. The thickness of the limiting portion can be any one of 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, and 1 mm, or within a range formed by any two of 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, and 1 mm. Regarding the injection space 240, the width and volume of the injection space can be increased by defining a groove on a surface of the limiting portion 210 facing the atomizing core body 300.Preferably, when the thickness of the protruding part 220 is 1.3 mm, the thickness of the limiting part 210 is 0.8 mm and the width of the injection space 240 is 0.85 mm, the atomizing device 10 has the desired performance, where the atomized liquid can easily enter the injection space 240, and liquid leakage, caused by excessive impact applied to the atomizing core assembly 300 due to injecting too much atomized liquid at once, can be avoided.

[0040] Furthermore, in the case where the injection space 240 gradually increases in width in the direction away from the protruding part 220, when the user When the atomizing device 10 is inhaled, the atomized liquid can be moved from bottom to top in the atomizing core assembly 300. In this case, the shape of the injection space 240 can ensure that the space for the movement of the atomized liquid gradually decreases, thus improving the tension of the atomized liquid and the adhesion of the atomized liquid to the limiting part 210 and to the atomizing core assembly 300, thus preventing the atomized liquid from being aspirated and transported.

[0041] Furthermore, if the height of the first injection hole 120 is equal to the height of the injection space 240, after the user has inserted the infusion element 20 into the first injection hole 120, a liquid outlet (not marked in the figure) of the infusion element 20 will be located just above the injection space 240, thus facilitating the entry of the atomized liquid into the injection space 240 through the communication opening.

[0042] Furthermore, with reference to FIGS. 7 to 9, the sealing element 200 further comprises a sealing element body 230. The sealing element body 230 defines a mounting hole (not shown in the figure). The atomizing core assembly 300 is located in the mounting hole and is fixedly connected to the sealing element body 230. The limiting portion 210 is disposed at an outer periphery of the mounting hole.

[0043] In this case, the sealing element 200 can be closely connected to the atomizing core assembly 300 to prevent the atomizing core assembly 300 and the sealing element 200 from sliding relative to each other, thus preventing the sealing element 200 from being unable to continuously mitigate the impact of the atomized liquid.

[0044] Furthermore, with reference to [Fig. 8] and [Fig. 9], the sealing element body 230 comprises a first sealing element body (not marked in the figure) and a second sealing element body (not marked in the figure) which are connected to each other. The first sealing element body is close to the inner side wall of the housing 100, and the second sealing element body is close to the atomizing core assembly 300 and is connected to the protruding portion 220. The height of the first sealing element body is greater than the height of the second sealing element body.

[0045] In this case, the height direction is the direction of a connecting line between the center of the base 600 and the center of the atomizing core assembly 300. Since the height of the first sealing element body is greater than the height of the second sealing element body, the atomized liquid can flow from the inner side wall of the housing 100 to the atomizing core assembly 300, so that when the atomizing device 10 contains less liquid Once atomized, the atomized liquid can still flow naturally towards the atomization core assembly 300.

[0046] It is understood that, as illustrated in [Fig. 8] and [Fig. 9], the second sealing element body may have an inclined surface, and in this case, the atomized liquid may flow smoothly along the inclined surface. Alternatively, there may be a difference in height between the first and second sealing element bodies, and in this case, the first and second sealing element bodies form a stepped shape, and the atomized liquid may still tend to flow towards the atomizing core assembly 300 due to the viscosity and fluidity of the atomized liquid.

[0047] Furthermore, with reference to FIGS. 7 to 9, there are multiple limiting parts 210 and multiple protruding parts 220, and the multiple limiting parts 210 are in one-to-one correspondence with the multiple protruding parts 220. The multiple limiting parts 210 are distributed symmetrically and circumferentially along the outer periphery of the fixing hole.

[0048] In this case, the limiting part 210 and the protruding part 220 can clamp the atomizing core assembly 300. Due to the symmetrical distribution of the multiple limiting parts 210 and the multiple protruding parts 220, the atomizing core assembly 300 is subjected to a uniform stress, so that the stability of the atomizing core assembly 300 can be improved.

[0049] Furthermore, with reference to FIGS. 7 to 9, a first elastic projection 250 is disposed on an internal side wall of the mounting hole. The first elastic projection 250 butts against the external side wall of the atomizing core assembly 300 to allow the atomizing core assembly 300 to fit tightly with the mounting hole.

[0050] In this case, the tight fit between the atomizing core assembly 300 and the fixing hole can further prevent relative slippage between the atomizing core assembly 300 and the sealing element 200.

[0051] In addition, the first elastic projection 250 is an annular projection; and / or there are multiple first elastic projections 250, and the multiple first elastic projections 250 are distributed in an axial direction of the fixing hole; and / or a second elastic projection 260 is further disposed on an external side wall of the sealing element body 230, and the second elastic projection 260 butts up against the internal side wall of the housing 100 to allow the sealing element body 230 to be in tight fit with the housing 100.

[0052] When the first elastic protrusion 250 is an annular protrusion and / or there are multiple first electrical protrusions, the outer side wall of the atomizing core assembly 300 is subjected to uniform forces at various positions, and the stability of the entire 300 atomizing core assembly is stronger. Similarly, the second elastic protrusion 260 can reinforce the structural strength between the sealing element 200 and the housing 100, and further prevent the sealing element 200 from slipping.

[0053] Furthermore, with reference to [Fig. 3] and Figs. 7 to 9, the outer side wall of the atomizing core assembly 300 defines a second injection hole 311. The second injection hole 311 allows the atomized liquid to flow into the interior of the atomizing core assembly 300 from the injection space 240. An orthographic projection of the limiting portion 210 onto the outer side wall of the atomizing core assembly 300 covers at least a portion of the second injection hole 311.

[0054] Generally, the second injection hole 311 allows the atomized liquid to enter the atomization core assembly 300 from the injection space 240. Therefore, to prevent the atomized liquid from entering the atomization core assembly 300 directly from the injection space 240, in embodiments, the limiting portion 210 covers the second injection hole 311. In this case, if the atomized liquid intends to impact the atomization core assembly 300 and enter it directly, the atomized liquid is necessarily buffered by the limiting portion 210. Furthermore, a material of the limiting portion 210 corresponds to the portion of the outer side wall of the atomization core assembly 300 that does not defining not the second injection hole 311 can be saved, thus reducing the production cost of the atomization device 10.

[0055] Furthermore, with reference to FIGS. 1 to 3, [Fig. 8], and [Fig. 9], the width direction of the housing 100 is the Y direction in [Fig. 1]. The width of the housing 100 is greater than its thickness. Two symmetrically distributed first receiving cavities (not marked in the figure) and two symmetrically distributed second receiving cavities (not marked in the figure) are defined between the atomizing core and the inner side wall of the housing 100. The first receiving cavity is larger than the second receiving cavity. The first injection hole 120 and the limiting portion 210 are both located in the first receiving cavity.

[0056] In the practical production of the atomizing device 10, the housing 100 of the atomizing device 10 may have an elliptical shape. In this case, the first injection hole 120 may be defined on a side of the housing 100 far from a central point of the housing 100, i.e., a side where the first receiving cavity is located.

[0057] In this case, the atomizing core assembly 300 is covered by the housing 100 on both sides of the second housing cavity, and the space between the atomizing core assembly 300 and the housing 100 is relatively small. Even if the core assembly The atomizing element 300 defines the second injection hole 311 on a side wall of the second receiving cavity, making it difficult for the atomized liquid to impact any part of the atomizing core assembly 300 in the second receiving cavity after the atomized liquid is injected by the infusion element 20. Therefore, it is not necessary to dispose of the protruding part 220 in the second receiving cavity, thus reducing the production cost of the atomizing device 10.

[0058] Furthermore, with reference to [Fig. 1], [Fig. 8], and [Fig. 9], the housing 100 is further provided with an elastic injection plug 111 corresponding to the first injection hole 120. The elastic injection plug 111 comprises a fixing portion 112 and a hinged portion 113. The fixing portion 112 is fixedly connected to the housing 100. The hinged portion 113 is connected to the fixing portion 112 and is removably connected to the first injection hole 120 and is hinged to block the first injection hole 120 or to connect the first injection hole with the infusion element 20.

[0059] In this case, in the atomizing device 10 of this embodiment, the elastic injection plug 111 can be hinged, so that the elastic injection plug 111 is deformed to block the first injection hole 120 or to make the first injection hole 120 communicate with the infusion element 20. Thus, the injection efficiency of the atomized liquid in the atomizing device 10 is improved.

[0060] When the atomizing device 10 is used, the atomized liquid is heated to form an aerosol, and the condensate formed by condensation of the atomized liquid and the aerosol in the atomizing device 10 will generally accumulate at the bottom of the atomizing device 10. In the related art, the random accumulation and flow of the atomized liquid and condensate often results in liquid leakage from the atomizing device 10, which affects the user experience and also reduces the service life of the atomizing device 10.

[0061] A liquid reservoir 610 can be a cavity or groove defined separately by the base 600, or a cavity defined by the liquid reservoir 610 and other components of the atomizing device 10 together.

[0062] To solve the technical problem described, reference may be made to FIGS. 1 to 5 and FIGS. 8 to 10. An atomizing device 10 is proposed in one embodiment of the invention. The atomizing device 10 comprises an atomizing core assembly 300, a support 400, and a base 600. A flow channel 312 is defined in the atomizing core assembly 300. The flow channel 312 allows the liquid to flow. The support 400 comprises a support body 410 and a guide portion 430. The guide portion 430 projects from the support body 410 and is connected to the bottom of the atomizing core assembly 300. A wall The outer lateral of the guide portion 430 has a guide surface 431. The guide surface 431 is either inclined or arc-shaped. A perimeter of the guide portion 430 gradually decreases in a direction in which the guide portion 430 protrudes. The base 600 defines a liquid reservoir 610. A portion of the support body 410 is located within the liquid reservoir 610. The guide surface 431 and a surface of the support body 410 facing the atomizing core assembly 300 define a guide channel 440. Two ends of the guide channel 440 are connected to the flow channel 312 and the liquid reservoir 610, respectively.

[0063] The directions indicated by the arrows in [Fig. 4], [Fig. 8], and [Fig. 10] are the flow directions of the atomized liquid and the condensate. It can be seen in the figures that the atomized liquid and the condensate flow from top to bottom inside the atomizing core assembly 300 onto the guiding surface 431. Since the guiding surface 431 is an inclined or arc-shaped surface, the perimeter of the guiding portion 430 gradually decreases in the direction in which the guiding portion 430 protrudes. Thus, the guiding surface 431 can guide the atomized liquid and the condensate to flow smoothly from the guiding portion 430 to a lateral edge of the support body 410.Since part of the support body 410 is located in the liquid reservoir 610, the thermal material to be heated and the condensate can flow smoothly towards the lateral edge of the support body 410, and then flow from the lateral edge of the support body 410 into the liquid reservoir 610. Therefore, in this embodiment, the objective of collecting the atomized liquid and the condensate in the liquid reservoir 610 is achieved, thus successfully preventing the atomized liquid and the condensate from accumulating and flowing randomly into the atomizing device 10.

[0064] Furthermore, referring to [Fig.3], [Fig.8], and [Fig.9], the liquid-absorbing fiber 500 is arranged in the liquid reservoir 610. The guide channel 440 is in communication with the liquid-absorbing fiber 500.

[0065] The liquid-absorbing fiber 500 comprises components such as liquid-absorbing cotton and can absorb the atomized liquid and condensate. In this case, the liquid-absorbing fiber 500 can prevent the atomized liquid and condensate from overflowing when the atomizing device 10 vibrates, thus preventing leakage of the atomized liquid and condensate.

[0066] Furthermore, with reference to [Fig. 3], [Fig. 8], and [Fig. 9], a mounting groove is defined at the bottom of the liquid reservoir 610. The liquid-absorbing fiber 500 comprises a first liquid-absorbing fiber 510 and a second liquid-absorbing fiber 520 stacked with the first liquid-absorbing fiber 510. The second liquid-absorbing fiber 520 is snapped into the mounting groove. The first liquid absorbing fiber 510 is clipped between the second liquid absorbing fiber 520 and an upper wall of the liquid reservoir 610.

[0067] In this case, the absorption capacity of the atomized liquid and condensate can be improved by means of the double-layer liquid-absorbing fiber 500. Furthermore, the first liquid-absorbing fiber 510 is clipped between the second liquid-absorbing fiber 520 and the upper wall of the liquid reservoir 610, so that it is not necessary to have an additional structure to fix the first liquid-absorbing fiber 510. Consequently, the internal space of the atomizing device 10 is fully utilized, the space utilization rate of the atomizing device 10 is further improved, and the production cost of the atomizing device 10 is reduced.

[0068] Furthermore, with reference to [Fig.8] and [Fig.9], the guide channel 440 is in communication with the first liquid-absorbing fiber 510; and / or an external side wall of the support body 410 and the side walls of the first liquid-absorbing fiber 510 and the second liquid-absorbing fiber 520 define a liquid-absorbing space.

[0069] The atomized liquid and condensate stored in the liquid reservoir 610 can rise into the atomizing core assembly 300 upon inhalation by the user and are heated a second time to form an aerosol. If the liquid to be heated is stored in the second liquid-absorbing fiber 520 but not in the first liquid-absorbing fiber 510, it is difficult for the atomized liquid and condensate to continuously rise into the atomizing core assembly 300.

[0070] In embodiments, since the guide channel 440 is in communication with the first liquid-absorbing fiber 510, after the atomized liquid and condensate flow through the lateral edge of the support body 410, the atomized liquid and condensate flow toward the first liquid-absorbing fiber 510 first. Once the first liquid-absorbing fiber 510 is fully stored, the atomized liquid and condensate gradually flow toward the second liquid-absorbing fiber 520. Therefore, a situation in which the first liquid-absorbing fiber 510 does not store any liquid while the second liquid-absorbing fiber 520 stores the liquid can be avoided.

[0071] Furthermore, with reference to [Fig. 8] and [Fig. 9], the second liquid-absorbing fiber 520 is located between the support body 410 and the base 600. The support body 410 defines a guide hole. The guide hole extends through the support body 410 and has one end in communication with an upper surface of the second liquid-absorbing fiber 520.

[0072] In some embodiments, the support body 410 may define a guide hole (not shown in the figure). The storage of the atomized liquid and condensate can be accelerated by means of the guide hole.

[0073] Furthermore, referring to FIGS. 4 to 10, the support 400 further has a first side wall 450 and a second side wall 460. The guide part 430, the first side wall 450, the second side wall 460 and a top surface of the support body 410 cooperatively define the guide channel 440.

[0074] In this case, the guide channel 440 has the shape of a sliding groove and can prevent the atomized liquid and condensate from flowing from the atomizing core assembly 300 to a part where the guide channel 440 is not defined. In other words, the atomized liquid and condensate are restricted to flow along a certain shape and path, thus preventing leakage of the atomized liquid and condensate.

[0075] Furthermore, with reference to FIGS. 8 to 12, the atomizing device 10 further comprises a liquid-absorbing element. The liquid-absorbing element has one end located in the guide channel 440 and the other end located in the flow channel 312.

[0076] In some cases, the user must inhale the atomized liquid and condensate from the liquid reservoir 610 or the guide channel 440 into the atomizing core assembly 300, and the flow of the liquid must be dependent on the solids. Therefore, in this embodiment, the liquid-absorbing element is further arranged, with one end of the liquid-absorbing element located in the guide channel 440 and the other end of the liquid-absorbing element located in the flow channel 312. In this case, the liquid can flow up the liquid-absorbing element, thus entering the flow channel 312 from the guide channel 440.

[0077] Furthermore, with reference to [Fig. 8] and [Fig. 9], the atomizing device 10 further comprises a housing 100 and a sealing element 200. The base 600 is connected to the bottom of the housing 100. The sealing element 200 is located within the housing 100 and is connected to an upper surface of the base 600. The sealing element 200 and the upper surface of the base 600 define a liquid reservoir 610.

[0078] In this case, the liquid reservoir 610 is defined cooperatively by the sealing element 200 and the base 600. The size of the liquid reservoir can vary with the distance between the sealing element 200 and the base 600.

[0079] With reference to Figures 11 and 12, Figures 11 and 12 illustrate the sealing element 200 provided in another embodiment of the invention. The sealing element 200 is located between the first injection hole and the core assembly atomization 300, and the sealing element 200 includes a blocking part 270 and a bypass part 280.

[0080] The blocking portion 270 is closer to the atomizing core assembly 300 than the bypass portion 280 and surrounds at least part of the side wall of the atomizing core assembly 300. The bypass portion 280 is located on one side of the blocking portion 270 near the first injection hole and protrudes towards the first injection hole.

[0081] More specifically, since the sealing element 200 is located between the atomizing core assembly 300 and the first injection hole, the atomized liquid flows through the sealing element 200 and then gradually flows towards the atomizing core assembly 300. Thus, the atomizing core assembly 300 can avoid being impacted by the atomized liquid, thereby preventing the atomizing device 10 from leaking oil.

[0082] When the atomized liquid is injected into the atomizing device 10 through the first injection hole using the infusion element 20, the atomized liquid exiting the infusion element 20 will not directly impact the atomizing core assembly 300 but will first come into contact with the bypass portion 280, which divides it into at least two streams of atomized liquid. This reduces the impact force of the atomized liquid exiting the infusion element 20, makes it uniformly distributed, then the two streams of atomized liquid come into contact with the blocking part 270, flow through the blocking part 270 and finally come into contact with the atomizing core assembly 300. In addition, since the blocking part 270 and the bypass part 280 block the flow of the atomized liquid in the Y direction and the X direction illustrated in [Fig.[l 1], the atomizing device 10 in this embodiment can also prevent the atomized liquid from shaking inside, thus improving the structural stability of the atomizing device 10. In summary, the atomizing device 10 in this embodiment can prevent leakage and improve structural stability.

[0083] It should be understood that the bypass portion 280 and the blocking portion 270 can be formed as a single unit, be removably connected, or exist independently. When the bypass portion 280 is connected to the blocking portion 270 or formed as a single unit with the blocking portion 270, the bypass portion 280 can improve the strength of the blocking portion 270.

[0084] Furthermore, the bypass portion 280 can be located in the middle of the blocking portion 270 to divide the blocking portion 270 into two symmetrical blocking sub-portions (not marked in the figure). In this case, since the two blocking sub-portions are symmetrical, the atomized liquid is divided into two streams flowing along the blocking portion towards the atomizing core assembly 300, with flow rates similar to both atomized liquid streams. This ensures equal contact areas between the 300 atomizing core assembly and the atomized liquid at different points, improving heating efficiency and the uniformity of the aerosol generated by the heating, thus improving the user's inhalation experience.

[0085] Furthermore, with reference to FIGS. 11 and 12, the thickness of the bypass portion 280 is less than the diameter of the first injection hole. An orthographic projection of at least a portion of the bypass portion 280 onto the blocking portion 270 lies within an orthographic projection of the first injection hole onto the blocking portion 270.

[0086] More specifically, a thickness direction of the bypass portion 280 is the X direction on [Fig. 1 1]. The orthographic projection should be understood as a projection range of the first injection hole along its central axis onto the blocking portion 270. Since the thickness of the bypass portion 280 is less than the diameter of the first injection hole, and since the orthographic projection of at least a portion of the bypass portion 280 onto the blocking portion 270 lies within the orthographic projection of the first injection hole onto the blocking portion 270, a liquid outlet diameter of the infusion element 20 (not marked in the figure) is also larger than that of the bypass portion 280.When the infusion element 20 is inserted into the first injection hole and the liquid outlet comes against the bypass part 280, the atomized liquid can still flow from the liquid outlet and will not be blocked by the bypass part 280.

[0087] In summary, the bypass portion 280 in this embodiment can prevent the infusion element 20 from directly butting against the blocking portion 270, which would otherwise completely seal the liquid outlet through the blocking portion 270. Compared to the related art without the sealing element 200, this embodiment can also prevent the liquid outlet from being sealed by the side wall of the atomizing core assembly 300.

[0088] Furthermore, with reference to FIGS. 11 and 12, at least a portion of the sealing element 200 and the outer side wall of the atomizing core assembly 300 cooperatively define the injection space 240. The injection space 240 allows the flow of the atomized liquid.

[0089] More specifically, if the sealing element 200 is in contact with the outer side wall of the atomizing core assembly 300, it can take a long time for the atomized liquid to come into contact with the atomizing core assembly 300, reducing the atomizing liquid generation efficiency of the atomizing device 10. In this embodiment, the sealing element 200 is at least partially located between the atomizing core assembly 300 and the first hole Injection space 240 is defined between at least a portion of the sealing element 200 and the outer side wall of the atomizing core assembly 300. Injection space 240 allows the flow of the atomized liquid. In this case, injection space 240 can prevent the atomized liquid from impacting the atomizing core assembly 300 while improving the speed at which the atomized liquid comes into contact with the atomizing core assembly 300.

[0090] Furthermore, with reference to FIGS. 11 and 12, one direction of the width of the injection space 240 is the Y direction on [Fig. 11]. The width of the injection space 240 varies from 0.5 mm to 1.2 mm.

[0091] More specifically, the side wall of the atomizing core assembly 300 defines the second injection hole 311. The atomized liquid must flow through the second injection hole 311 into the atomizing core assembly 300. In other words, when the user inhales from the atomizing device 10, the atomized liquid moves from bottom to top to the second injection hole 311, then enters the atomizing core assembly 300 to be heated to generate an aerosol. When the width of the injection space 240 is between 0.5 mm and 1.2 mm, the atomized liquid can create a liquid flow gap phenomenon within the injection space 240. The liquid flow is caused by a pure pressure difference, i.e., pressure differential flow.This avoids inefficient obstruction of the atomized liquid's impact on the atomizing core assembly 300 due to an overly large injection space 240 and also allows the atomized liquid to rise along the injection space 240, facilitating the entry of the atomized liquid into the atomizing core assembly 300, along the injection space 240, through the second injection hole 311 on the outer side wall of the atomizing core assembly 300.

[0092] It can be understood that the width of the injection space 240 can be any one of 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm and 1.2 mm, or in a range formed by any two of 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm and 1 mm.

[0093] Furthermore, referring to FIGS. 11 and 12, the injection space 240 gradually increases in width in a direction from the bottom of the atomization core assembly 300 to the top of the atomization core assembly 300.

[0094] More specifically, in the case where the injection space 240 gradually increases in width from the bottom to the top of the atomizing core assembly 300, when the user inhales the atomizing device 10, the shape of the injection space 240 can ensure that the space allowing the atomized liquid to move gradually decreases, thus improving the tension of the atomized liquid. and the adhesion of the atomized liquid to the sealing element 200 and to the atomizing core assembly 300, preventing the atomized liquid from being aspirated and transported.

[0095] Furthermore, with reference to FIGS. 11 and 12, the sealing element 200 is implemented in the form of multiple sealing elements which are distributed symmetrically and circumferentially along an external periphery of the atomizing core assembly 300.

[0096] More specifically, in this case, the multiple sealing elements 200 can clamp the atomizing core assembly 300. The symmetrical distribution of the multiple sealing elements 200 can ensure that the atomizing core assembly 300 is subjected to uniform stress, so that the stability of the atomizing core assembly 300 can be improved.

[0097] Furthermore, with reference to FIGS. 11 and 12, the sealing element 200 is elastic.

[0098] More specifically, in this case, when the infusion element 20 is pressed against the sealing element 200 with a certain force, the sealing element 200 can deform and adapt to the side wall of the atomizing core assembly 300, thus protecting the side wall of the atomizing core assembly 300 from deformation and further preventing the atomized liquid from impacting the atomizing core assembly 300.

[0099] Furthermore, with reference to FIGS. 11 and 12, the sealing element 200 further comprises the sealing element body 230. The sealing element body 230 defines a fixing hole (not marked in the figure), the atomizing core assembly 300 is located in the fixing hole and fixedly connected to the sealing element body 230. The blocking part 270 is disposed at the external periphery of the fixing hole.

[0100] In this case, the sealing element 200 can be closely connected to the atomizing core assembly 300 to prevent the atomizing core assembly 300 and the sealing element 200 from sliding relative to each other, thus preventing the sealing element 200 from being unable to continuously mitigate the impact of the atomized liquid.

[0101] Furthermore, the sealing element body 230 comprises a first sealing element body 230 and a second sealing element body 230 connected to each other. The first sealing element body 230 is close to the inner side wall of the housing 100, and the second sealing element body 230 is close to the atomizing core assembly 300 and is connected to the blocking portion 270. The height of the first sealing element body 230 is greater than the height of the second sealing element body 230.

[0102] Furthermore, with reference to [Fig. 11] and [Fig. 12], the sealing element body 230 comprises a first sealing element body (not marked in the figure) and a second sealing element body (not marked in the figure) which are connected to each other. the other. The first sealing element body is close to the inner side wall of the housing 100, and the second sealing element body is close to the atomizing core assembly 300 and is connected to the blocking part 270. The height of the first sealing element body is greater than the height of the second sealing element body.

[0103] In this case, the height direction is the Z direction on [Fig. 1 1]. Since the height of the first sealing element body is greater than the height of the second sealing element body, the atomized liquid can flow from the inner side wall of the housing 100 to the atomizing core assembly 300, so that when the atomizing device 10 contains less atomized liquid, the atomized liquid can still flow naturally to the atomizing core assembly 300 under the action of gravity.

[0104] It is understood that, as illustrated in [Fig. 11] and [Fig. 12], the second sealing element body may have an inclined surface, and in this case, the atomized liquid may flow smoothly along the inclined surface. Alternatively, there may be a difference in height between the first and second sealing element bodies, and in this case, the first and second sealing element bodies form a stepped shape, and the atomized liquid may still tend to flow towards the atomizing core assembly 300 due to the viscosity and fluidity of the atomized liquid.

[0105] Furthermore, with reference to FIGS. 4 to 6 and FIGS. 8 to 10, a first mounting hole 420 is located in the middle of the guide portion 430. The bottom of the atomizing core assembly 300 covers the first mounting hole 420. The atomizing core assembly 300 further includes a thread 320. The thread 320 passes through the first mounting hole 420.

[0106] In this case, the atomizing core assembly 300 covers the first mounting hole 420, so that the wire 320 can be prevented from being hit, and that the atomized liquid and condensate can be prevented from flowing into the first mounting hole 420.

[0107] Furthermore, an inhalation channel 313 is defined at the top of the atomizing core assembly 300 and allows the aerosol to pass through. The inhalation channel 313 communicates with the flow channel 312 and the external environment. A flow zone of the inhalation channel 313 gradually decreases in a direction from the flow channel 312 towards the external environment.

[0108] When the atomizing core assembly 300 in the atomizing device 10 heats the atomized liquid to produce an aerosol, the aerosol flows into the external environment through the inhalation channel 313. Part of the aerosol will condense to form condensate due to contact with the side wall of the inhalation channel 313 or the decrease in temperature. In this embodiment of the invention, the flow surface of the inhalation channel 313 gradually decreases, so that the volume of the aerosol is reduced and compressed in the outward flow process, and the aerosol flow rate in contact with the side wall increases, so that the condensate forms more easily, thus achieving the repeated use of the atomizing device 10.

[0109] In certain embodiments, with reference to FIGS. From steps 1 to 3, assembling the atomizing device 10 first involves installing the atomizing core assembly 300 onto the support 400. Next, place an oil-absorbing fiber 500 onto the base 600, mount the support 400 onto the base 600, and pass the electrode 700 through the base 600, the oil-absorbing fiber 500, and the support 400 to connect it to the atomizing core assembly 300. Then, insert the elastic injection plug 111 into the housing 100 (which can serve as a nozzle) and sleeve the sealing element 200 onto the atomizing core assembly 300. Finally, connect the housing 100 and the base 600, encapsulating the remaining components and completing the assembly of the atomizing device 10.

[0110] Furthermore, in another embodiment of the invention, the elastic injection plug 111 corresponding to the first injection hole on the housing 100 is illustrated in FIGS. 13 to 15. The elastic injection plug 111 comprises the fastening portion 112 and the hinged portion 113. The fastening portion 112 is connected to the housing 100. The hinged portion 113 is connected to the fastening portion 112. The portion is removably connected to the first injection hole and is hinged to block the first injection hole or to connect the first injection hole with the infusion element 20.

[0111] More specifically, in the atomizing device 10 of this embodiment, the elastic injection plug 111 can be hinged, so that the elastic injection plug 111 is deformed to block the first injection hole 120 or to make the first injection hole 120 communicate with the infusion element 20. Thus, the injection efficiency of the atomized liquid in the atomizing device 10 is improved.

[0112] Furthermore, with reference to FIGS. 13 to 15, the housing 100 defines a mounting groove 110 and a limiting portion 140. The fixing portion 112 and the hinged portion 113 are located in the mounting groove 110. The hinged portion 113 has a pressure portion 114 at one end of the hinged portion 113 opposite the fixing portion 112. The limiting portion 140 is located at one end of an outer periphery of the mounting groove 110 near the pressure portion 114. When the pressure portion 114 abuts against the side wall of the limiting portion 140, the pressure portion 114 and a lower wall The mounting groove 110 cooperatively defines a deformation chamber 130. A side wall of the limiting part 140 and the side wall of the mounting groove 110 cooperatively define a limiting chamber (not marked in the figure), and a side wall of the elastic injection plug 111 is located inside the limiting chamber.

[0113] More specifically, to prevent accidental release of the elastic injection plug 111 leading to the opening of the first injection hole, the atomizing device 10 requires further improvement. In this embodiment, when the limiting portion 140 abuts against the pressure portion 114, the side wall of the elastic injection plug 111 is located inside the limiting chamber defined by the side wall of the limiting portion 140 and the side wall of the mounting groove 110. This means that the elastic injection plug 111 is positioned inside the housing 100, making it impossible for the user to grasp or lift the elastic injection plug 111, thus preventing accidental release and opening of the elastic injection plug 111.

[0114] The specific steps for opening the elastic injection plug 111 in this embodiment are as follows.

[0115] First, press the pressure portion 114 towards the deformation chamber 130. At this point, the pressure portion 114 bends inside the deformation chamber 130 and tilts in a direction opposite to the housing 100, allowing the user to grasp the pressure portion 114. Then, by grasping the pressure portion 114, the reversing portion 113 can move out of the first injection hole, allowing the first injection hole to be opened. Subsequently, insert the infusion element 20 into the first injection hole and infuse the atomized liquid.

[0116] Furthermore, with reference to [Fig. 11] and [Fig. 12], the width direction of the housing 100 is the Y direction in [Fig. 11], and the thickness direction of the housing 100 is the X direction in [Fig. 11]. The width of the housing 100 is greater than the thickness of the housing 100; the atomizing core assembly 300 and the inner side wall of the housing 100 cooperatively define the first two symmetrically distributed housing chambers (not marked in the figure) and the second two symmetrically distributed housing chambers (not marked in the figure).

[0117] The first receiving chamber is larger than the second receiving chamber, and the first injection hole and the sealing element are located in the first receiving chamber.

[0118] During the actual production of the atomizing device 10, the housing 100 of the atomizing device 10 may have an elliptical shape. In this case, the first injection hole may be defined on a side of the housing 100 far from the center point of the housing 100, i.e., a side where the first receiving chamber is located.

[0119] In this case, the atomizing core assembly 300 is covered by the housing 100 on both sides of the second housing chamber, and the space between the atomizing core assembly 300 and the housing 100 is relatively small. Even though the atomizing core assembly 300 defines the second injection hole 310 on the side wall of the second receiving chamber, it is difficult for the atomized liquid to impact any part of the atomizing core assembly 300 in the second receiving chamber after the atomized liquid is injected by the perfusion device 20. Therefore, it is not necessary to place the sealing element in the second receiving chamber, thus reducing the production cost of the atomizing device 10.

[0120] It may be understood that the atomization device in the above embodiments includes, but is not limited to, devices such as an aerosol generating device, an aromatherapy machine, a drug atomizer, a sprinkler fire protection system, a cleaning device, an irrigation device, a cosmetic device and a laboratory solute extraction device.
