Description

Title of the invention: ATOMIZATION DEVICE Technical field

[0001] This publication relates to the field of atomizing devices and, in particular, to an atomizing device. Prior art

[0002] An existing atomizing device includes a main body and an atomizing core assembly, where 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 therein and is configured to generate an aerosol and allows 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 atomized liquid to the atomizing device to prevent the atomizing core assembly from dry burning. In the related art, when atomized liquid is added to the atomizing device, the large flow rate of the added atomized liquid can easily cause it to impact the atomizing core assembly, leading to leakage of the atomized liquid.

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

[0005] In order to solve the above technical problem, an atomizing device is provided in the embodiments of the invention. The atomizing device comprises an atomizing core assembly, a sealing member, 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 member are connected to each other and both are located inside the housing. The sealing member is at least partially located between the atomizing core assembly and the first injection hole.

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

[0007] In the invention, the sealing member 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 member, the atomized liquid flowing out of the infusion member cannot directly contact or impact the atomizing core assembly. Instead, the atomized liquid will first contact the sealing member, 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 leakage. Brief description of the drawings

Detailed description of the embodiments

[0024] Unless otherwise defined, all technology and scientific terms used in the invention have common meanings that can be understood by those skilled in the art. All terms used in the invention are intended only to illustrate specific embodiments, but are not intended to limit the invention. The terms "comprising", "contains", "having" and any 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 "embodiment" 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. Expressions in the invention are not required to refer to the same embodiment and do not refer to an independent embodiment and an alternative embodiment which are exclusive to other embodiments. It may be explicitly and implicitly understood by those skilled in the art that the embodiments described in the invention may be combined with other embodiments.

[0026] To solve the described problem, with reference to [Fig.l] to 3 and FIGS. 7 to 9, an atomizing device 10 is provided in the embodiments. The An 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 atomized liquid. The atomizing core assembly 300 and the sealing element 200 are connected to each other and both are located within 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 member 200 is located between the atomizing core assembly 300 and the first injection hole 120, by the method illustrated in [Fig. 9], when a user uses an infusion member 20 to inject the atomized liquid into the atomizing device 10 through the first injection hole 120, the atomized liquid flowing out of the infusion member 20 will not directly contact and impact the atomizing core assembly 300, but first contacts the sealing member 200 and then gradually flows into the atomizing core assembly 300.

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

[0029] Furthermore, if the sealing member 200 is in contact with an outer sidewall of the atomizing core assembly 300, it may take a long time for the atomized liquid to contact the atomizing core assembly 300, resulting in a decrease in heating efficiency. In this embodiment, the sealing member 200 is at least partially located between the atomizing core assembly 300 and the first injection hole 120. An injection gap 240 is defined between at least a portion of the sealing member 200 and the outer sidewall of the atomizing core assembly 300. The injection gap 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 contacts the atomizing core assembly 300.

[0030] Further, referring to FIGS. 7 to 9, the sealing member 200 comprises a limiting portion 210 and a protruding portion 220 connected to each other. The injection space 240 is defined between the limiting portion 210 and the outer sidewall of the atomizing core assembly 300.

[0031] The protruding portion 220 is located at one end of the limiting portion 210 near the first injection hole 120. The protruding portion 220 projects toward the outer side wall of the atomizing core assembly 300 and abuts against the outer side wall of the atomizing core assembly 300.

[0032] When injecting the atomized liquid into the atomizing device 10 in practical use, the atomized liquid may impact the sealing member 200 to cause deformation of the sealing member 200, and thus, it is not possible to achieve the effect of preventing the atomized liquid from impacting the atomizing core assembly 300. In this embodiment, by arranging the protruding portion 220, the protruding portion 220 can prevent the deformation of the limiting portion 210 by contacting the outer side wall of the atomizing core assembly 300 when the atomized liquid impacts the sealing member 200.

[0033] Further, a thickness of the protruding portion 220 is less than a thickness of the limiting portion 210 to define a communication opening (not marked in 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 some embodiments, when the sealing member 200 surrounds the side wall of the atomizing core assembly 300, or when a part of the side wall of the atomizing core assembly 300 not covered by the sealing member 200 is covered by other components, the atomized liquid can only enter the injection space 240 through the communication opening, and then enter the interior of the atomizing core assembly 300. In this case, it is further possible to prevent the atomized liquid from impacting the atomizing core assembly 300. When the atomized liquid is added, the infusion member 20 can be aligned with the communication opening to allow the atomized liquid to enter the injection space 240 through the communication opening, thereby improving the injection efficiency of the liquid. atomized.

[0035] Further, referring to [Fig.7] and [Fig.8], a width of the injection space 240 varies from 0.5 mm to 1 mm; and / or the thickness of the protruding portion 220 varies from 1.1 mm to 1.5 mm, and the thickness of the limiting portion 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 portion 220; and / or a height of the first injection hole 120 is equal to a height of the injection space 240.

[0036] In [Fig.7], a height direction is the Z direction, and a width direction is the Y direction.

[0037] When the width of the injection gap 240 is between 0.5 mm and 1 mm, the atomized liquid can form a liquid flow gap phenomenon in the injection gap 240. The liquid flow rate is caused by a pure pressure difference, i.e., the pressure difference flow rate. This can avoid ineffective obstruction of the atomized liquid impact on the core assembly. atomizing core assembly 300 due to an injection gap 240 that is too wide and also allows the atomized liquid to rise along the injection gap 240, facilitating the entry of the atomized liquid into the interior of the atomizing core assembly 300, along the injection gap 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 should be greater than the thickness of the limiting portion 210, so that when the protruding portion 220 abuts against 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 portion 220 and the thickness of the limiting portion 210 in the invention, the atomized liquid can easily enter the injection space 240, and liquid leakage can be avoided, the liquid leakage being caused by excessive impact applied to the atomizing core assembly 300 due to injecting too much atomized liquid at one time.

[0039] It can be understood that the width of the injection gap 240 may be any one of 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm and 1 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. The thickness of the protruding portion may be any one of 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm and 1.5 mm, or in 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 may 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 may 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 portion 220 is 1.3 mm, the thickness of the limiting portion 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 the liquid leakage, caused by excessive impact applied to the atomizing core assembly 300 due to injecting too much atomized liquid at one time, can be avoided.

[0040] Furthermore, in the case where the injection space 240 gradually increases in width in the direction away from the protruding portion 220, when the user inhales the atomizing device 10, 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, thereby improving the tension of the atomized liquid and the adhesion of the atomized liquid to the limiting portion 210 and the atomizing core assembly 300, thereby avoiding that the atomized liquid cannot be sucked and transported.

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

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

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

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

[0045] In this case, the height direction is a 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 member body is greater than the height of the second sealing member 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 atomized, the atomized liquid can still flow naturally to the atomizing 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 height difference between the first sealing element body and the second sealing element body, and in this case, the first sealing element body and the second sealing element body form a stepped shape, and the atomized liquid may still tend to flow toward the atomizing core assembly 300 due to the viscosity and fluidity of the atomized liquid.

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

[0048] In this case, the limiting portion 210 and the protruding portion 220 can clamp the atomizing core assembly 300. Due to the symmetrical distribution of the multiple limiting portions 210 and the multiple protruding portions 220, the atomizing core assembly 300 is uniformly stressed, so that the stability of the atomizing core assembly 300 can be improved.

[0049] Further, referring to FIGS. 7-9, a first elastic protrusion 250 is disposed on an inner side wall of the fixing hole. The first elastic protrusion 250 abuts the outer side wall of the atomizing core assembly 300 to enable the atomizing core assembly 300 to be in a tight fit with the fixing hole.

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

[0051] Furthermore, the first elastic protrusion 250 is an annular protrusion; and / or there are multiple first elastic protrusions 250, and the multiple first elastic protrusions 250 are distributed in an axial direction of the fixing hole; and / or a second elastic protrusion 260 is further provided on an outer side wall of the sealing member body 230, and the second elastic protrusion 260 abuts against the inner side wall of the housing 100 to enable the sealing member body 230 to be in an interference 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 atomizing core assembly 300 is stronger. Similarly, the second elastic protrusion 260 can strengthen the structural strength between the sealing member 200 and the housing 100, and further prevent the sealing member 200 from sliding.

[0053] Further, referring 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 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 on 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 interior of the atomizing core assembly 300 from the injection space 240, so that, in order to prevent the atomized liquid from entering the interior of the atomizing core assembly 300 directly from the injection space 240, in the embodiments, the limiting portion 210 covers the second injection hole 311. In this case, if the atomized liquid intends to impact the atomizing core assembly 300 and directly enter the interior of the atomizing core assembly 300, the atomized liquid is necessarily buffered by the limiting portion 210. In addition, a material of the limiting portion 210 corresponding to the portion of the outer side wall of the atomizing core assembly 300 which does not define the second injection hole 311 can be saved, thereby reducing the production cost of the atomizing device 10.

[0055] Further, referring 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 the thickness of the housing 100. 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 remote 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 gap between the atomizing core assembly 300 and the housing 100 is relatively small. Even if the core assembly atomizing core assembly 300 defines the second injection hole 311 on a side wall of the second receiving cavity, it is difficult for the atomized liquid to impact a part of the atomizing core assembly 300 in the second receiving cavity after the atomized liquid is injected by the infusion member 20. Therefore, there is no need to arrange the protruding portion 220 in the second receiving cavity, thereby reducing the production cost of the atomizing device 10.

[0058] Furthermore, referring to [Fig.l], [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 folding portion 113. The fixing portion 112 is fixedly connected to the housing 100. The folding portion 113 is connected to the fixing portion 112 and is removably connected to the first injection hole 120 and is folding to block the first injection hole 120 or communicate the first injection hole with the infusion member 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 communicate the first injection hole 120 with the infusion member 20. Thus, the injection efficiency of the atomized liquid into 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 the condensate often cause liquid to leak 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 may 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 described technical problem, reference may be made to FIGS. 1 to 5 and FIGS. 8 to 10. An atomizing device 10 is provided in one embodiment of the invention. The atomizing device 10 comprises an atomizing core assembly 300, a holder 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 holder 400 comprises a holder body 410 and a guide portion 430. The guide portion 430 protrudes from the holder body 410 and is connected to the bottom of the atomizing core assembly 300. A wall The outer side of the guide portion 430 has a guide surface 431. The guide surface 431 is an inclined surface or an arc surface. 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 in 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 respectively in communication with the flow channel 312 and the liquid reservoir 610.

[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 from the figures that the atomized liquid and the condensate flow from top to bottom inside the atomizing core assembly 300 on the guide surface 431, and since the guide surface 431 is an inclined surface or an arc surface, the perimeter of the guide portion 430 gradually decreases in the direction in which the guide portion 430 protrudes, thus the guide surface 431 can guide the atomized liquid and the condensate to flow smoothly from the guide portion 430 to a side edge of the support body 410.Since a part of the support body 410 is located in the liquid reservoir 610, the thermal material to be heated and the condensate can smoothly flow to the side edge of the support body 410, and then flow from the side edge of the support body 410 into the liquid reservoir 610. Therefore, in this embodiment, the purpose of gathering the atomized liquid and the condensate in the liquid reservoir 610 is realized, thereby successfully preventing the atomized liquid and the condensate from accumulating and flowing randomly in the atomizing device 10.

[0064] Further, referring to [Fig.3], [Fig.8], and [Fig.9], the liquid absorbing fiber 500 is disposed 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 the condensate. In this case, the liquid-absorbing fiber 500 can prevent the atomized liquid and the condensate from overflowing when the atomizing device 10 shakes, thereby preventing leakage of the atomized liquid and the condensate.

[0066] Further, referring to [Fig.3], [Fig.8], and [Fig.9], a fixing 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 fixing groove. The first liquid absorbing fiber 510 is snapped between the second liquid absorbing fiber 520 and a top wall of the liquid reservoir 610.

[0067] In this case, the absorption amount of the atomized liquid and the condensate can be improved by means of the double-layer liquid-absorbing fiber 500. In addition, the first liquid-absorbing fiber 510 is snapped between the second liquid-absorbing fiber 520 and the upper wall of the liquid tank 610, so that it is not necessary to additionally provide a structure for fixing the first liquid-absorbing fiber 510. Therefore, the interior 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] Further, referring to [Fig.8] and [Fig.9], the guide channel 440 is in communication with the first liquid-absorbing fiber 510; and / or an outer 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 to the interior of the atomizing core assembly 300 under the inhalation of 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 in the atomizing core assembly 300.

[0070] In the 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 side edge of the support body 410, the atomized liquid and condensate flow toward the first liquid-absorbing fiber 510 first. After 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 liquid while the second liquid-absorbing fiber 520 stores liquid can be avoided.

[0071] Further, referring 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 marked in the figure). Storage of the atomized liquid and condensate may be accelerated by the guide hole.

[0073] Further, referring to FIGS. 4-10, the support 400 further has a first side wall 450 and a second side wall 460. The guide portion 430, the first side wall 450, the second side wall 460, and an upper 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 the condensate from flowing from the atomizing core assembly 300 to a portion where the guide channel 440 is not defined. In other words, the atomized liquid and the condensate are limited to flowing in a certain shape and path, thereby preventing leakage of the atomized liquid and the condensate.

[0075] Further, referring to FIGS. 8-12, the atomizing device 10 further comprises a liquid absorbing member. The liquid absorbing member 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 needs to inhale the atomized liquid and condensate in the liquid reservoir 610 or the guide channel 440 into the atomizing core assembly 300, and the liquid flow needs to depend on the solids. Therefore, in this embodiment, the liquid absorbing member is additionally arranged, one end of the liquid absorbing member is located in the guide channel 440, and the other end of the liquid absorbing member is located in the flow channel 312. In this case, the liquid can flow up along the liquid absorbing member, thereby entering the flow channel 312 from the guide channel 440.

[0077] Further, referring 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 in 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 cooperatively defined by the sealing element 200 and the base 600. The size of the liquid reservoir may vary with the distance between the sealing element 200 and the base 600.

[0079] Referring to [Fig. 11] and 12, FIGS. 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 atomizing element 300, and the sealing element 200 comprises a blocking portion 270 and a bypass portion 280.

[0080] The blocking portion 270 is closer to the atomizing core assembly 300 than the bypass portion 280 and surrounds at least a portion 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 toward the first injection hole.

[0081] More specifically, since the sealing member 200 is located between the atomizing core assembly 300 and the first injection hole, the atomized liquid flows through the sealing member 200 and then gradually flows toward 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 member 20, the atomized liquid exiting the infusion member 20 will not directly impact the atomizing core assembly 300 but will first contact the branch portion 280, which divides it into at least two atomized liquid streams. This reduces the impact force of the atomized liquid flowing out of the infusion element 20, makes it evenly distributed, and then the two atomized liquid streams contact the blocking portion 270, flow through the blocking portion 270, and finally contact the atomizing core assembly 300. In addition, since the blocking portion 270 and the bypass portion 280 block the flow of the atomized liquid in the Y direction and the X direction shown in [Fig.l 1], the atomizing device 10 in this embodiment can also prevent the atomized liquid from shaking inside, thereby improving the structural stability of the atomizing device 10. In summary, the atomizing device 10 in this embodiment can prevent leakage and improve the structural stability.

[0083] It should be understood that the bypass portion 280 and the locking portion 270 may be integrally formed, removably connected, or exist independently. When the bypass portion 280 is connected to the locking portion 270 or integrally formed with the locking portion 270, the bypass portion 280 may improve the strength of the locking portion 270.

[0084] Furthermore, the branch portion 280 may 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 to the atomizing core assembly 300, with flow rates similar of the two atomized liquid streams. This ensures equal contact areas between the atomizing core assembly 300 and the atomized liquid at different points, improving the heating efficiency and the uniformity of the aerosol generated by the heating, thereby improving the user's inhalation experience.

[0085] Further, referring 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 is located within an orthographic projection of the first injection hole onto the blocking portion 270.

[0086] More specifically, a thickness direction of the branch portion 280 is the X direction in [Fig.l 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 branch portion 280 is less than the diameter of the first injection hole, and the orthographic projection of at least a portion of the branch portion 280 onto the blocking portion 270 is located 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 the branch portion 280.When the infusion member 20 is inserted into the first injection hole and the liquid outlet abuts against the bypass portion 280, the atomized liquid can still flow out from the liquid outlet and will not be blocked by the bypass portion 280.

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

[0088] Further, referring to FIGS. 11 and 12, at least a portion of the sealing member 200 and the outer sidewall 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 member 200 is in contact with the outer side wall of the atomizing core assembly 300, it may take a long time for the atomized liquid to contact the atomizing core assembly 300, reducing the atomized liquid generation efficiency of the atomizing device 10. In this embodiment, the sealing member 200 is at least partially located between the atomizing core assembly 300 and the first hole injection. The injection space 240 is defined between at least a portion of the sealing member 200 and the outer sidewall 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 contacts the atomizing core assembly 300.

[0090] Further, referring to FIGS. 11 and 12, a width direction of the injection gap 240 is the Y direction in [Fig.l 1]. The width of the injection gap 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 is to flow through the second injection hole 311 to the inside of the atomizing core assembly 300. That is, when the user inhales the atomizing device 10, the atomized liquid moves from bottom to top to the second injection hole 311, and then enters the atomizing core assembly 300 to be heated to generate an aerosol. When the width of the injection gap 240 is between 0.5 mm and 1.2 mm, the atomized liquid can form a liquid flow gap phenomenon in the injection gap 240. The liquid flow rate is caused by a pure pressure difference, i.e., the pressure difference flow rate.This avoids ineffective obstruction of the impact of the atomized liquid on the atomizing core assembly 300 due to an overly wide injection gap 240 and also allows the atomized liquid to rise along the injection gap 240, facilitating the entry of the atomized liquid into the interior of the atomizing core assembly 300, along the injection gap 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 gap 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] Further, referring to FIGS. 11 and 12, the injection space 240 gradually increases in width in a direction from the bottom of the atomizing core assembly 300 toward the top of the atomizing core assembly 300.

[0094] More specifically, in the case where the injection space 240 gradually increases in width in the direction 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 for the atomized liquid to move gradually decreases, thereby improving the tension of the atomized liquid. and adhering the atomized liquid to the sealing member 200 and the atomizing core assembly 300, preventing the atomized liquid from not being sucked and transported.

[0095] Further, referring to FIGS. 11 and 12, the sealing element 200 is implemented as multiple sealing elements that are symmetrically and circumferentially distributed along an outer periphery of the atomizing core assembly 300.

[0096] More specifically, in this case, the multiple sealing members 200 can clamp the atomizing core assembly 300. The symmetrical distribution of the multiple sealing members 200 can ensure that the atomizing core assembly 300 is uniformly stressed, so that the stability of the atomizing core assembly 300 can be improved.

[0097] Further, referring to FIGS. 11 and 12, the sealing element 200 is elastic.

[0098] More specifically, in this case, when the infusion member 20 is pressed against the sealing member 200 with a certain force, the sealing member 200 can deform and fit the side wall of the atomizing core assembly 300, thereby 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] Further, referring to FIGS. 11 and 12, the sealing member 200 further comprises the sealing member body 230. The sealing member 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 member body 230. The locking portion 270 is disposed at the outer periphery of the fixing hole.

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

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

[0102] Further, referring 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 portion 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 in [Fig.l 1]. Since the height of the first sealing member body is greater than the height of the second sealing member 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 height difference between the first sealing element body and the second sealing element body, and in this case, the first sealing element body and the second sealing element body form a stepped shape, and the atomized liquid may still tend to flow toward the atomizing core assembly 300 due to the viscosity and fluidity of the atomized liquid.

[0105] Further, referring to FIGS. 4-6 and FIGS. 8-10, a first mounting hole 420 is disposed 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 comprises a wire 320. The wire 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 struck, and the atomized liquid and condensate can be prevented from flowing into the first mounting hole 420.

[0107] Further, an inhalation channel 313 is defined at the top of the atomizing core assembly 300 and allows the aerosol to pass therethrough. The inhalation channel 313 is in communication with the flow channel 312 and the external environment. A flow area of the inhalation channel 313 gradually decreases in a direction from the flow channel 312 toward 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 to the external environment through the inhalation channel 313. A portion of the aerosol will condense to form condensate due to contact with the sidewall of the inhalation channel 313 or the temperature decrease. In this embodiment of the invention, the flow area of the inhalation channel 313 gradually decreases, so that the volume of the aerosol is reduced and compressed in the process of flowing outward, and the aerosol flow rate in contact with the side wall increases, so that condensate is formed more easily, thereby realizing the repeated use of the atomizing device 10.

[0109] In certain embodiments, with reference to FIGS. 1 to 3, the assembly of the atomizing device 10 involves first installing the atomizing core assembly 300 on the holder 400. Then, place an oil-absorbing fiber 500 on the base 600, mount the holder 400 on the base 600, and pass the electrode 700 through the base 600, the oil-absorbing fiber 500, and the holder 400 to connect it to the atomizing core assembly 300. Next, insert the elastic injection plug 111 into the housing 100 (which can serve as a tip) and sleeve the sealing member 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] Further, 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 fixing portion 112 and the folding portion 113. The fixing portion 112 is connected to the housing 100. The folding portion 113 is connected to the fixing portion 112. The portion is removably connected to the first injection hole and is folding to block the first injection hole or communicate 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 make the first injection hole 120 communicate with the infusion element 20. Thus, the injection efficiency of the atomized liquid into the atomizing device 10 is improved.

[0112] Further, referring to FIGS. 13 to 15, the housing 100 defines a mounting groove 110 and a limiting portion 140. The fixing portion 112 and the folding portion 113 are located in the mounting groove 110. The folding portion 113 has a pressing portion 114 at one end of the folding portion 113 away from the fixing portion 112. The limiting portion 140 is located at one end of an outer periphery of the mounting groove 110 near the pressing portion 114. When the pressing portion 114 abuts against the side wall of the limiting portion 140, the pressing portion 114 and a bottom wall of the mounting groove 110 cooperatively define a deformation chamber 130. A side wall of the limiting portion 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 triggering of the elastic injection plug 111 leading to the opening of the first injection hole, the atomizing device 10 still requires improvement. In this embodiment, when the limiting portion 140 abuts against the pressing 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, thereby preventing accidental triggering 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 pressing portion 114 toward the deformation chamber 130. At this time, the pressing portion 114 bends inside the deformation chamber 130 and tilts in a direction opposite to the housing 100, allowing the user to grasp the pressing portion 114. Then, by grasping the pressing portion 114, the turning portion 113 can leave the first injection hole, allowing the first injection hole to be opened. Thereafter, insert the infusion member 20 into the first injection hole and infuse the atomized liquid.

[0116] Further, referring to [Fig.l 1] 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.l 1]. 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 two symmetrically distributed first housing chambers (not marked in the figure) and the two symmetrically distributed second 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] In 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 away 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 gap between the atomizing core assembly 300 and the housing 100 is relatively small. Even if 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 a part of the atomizing core assembly 300 in the second receiving chamber after the atomized liquid is injected by the perfusion member 20. Therefore, it is not necessary to arrange the sealing member in the second receiving chamber, thereby reducing the production cost of the atomizing device 10.

[0120] It can 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 medicine atomizer, a sprinkler fire protection system, a cleaning device, an irrigation device, a cosmetic device, and a laboratory solute extraction device.
