Description

Technical Field

[0001] The exemplary embodiments of the present disclosure generally relate to the field of atomization devices, and in particular to an atomization device and an atomization apparatus. Background Art

[0002] The atomizer is a key component that converts the atomized matrix into an inhalable aerosol. Some atomizers allow users to add the atomized matrix. The atomized matrix is ​​injected into the liquid storage chamber of the atomizer mainly from the mouthpiece end, and the mouthpiece is assembled after the injection is completed. In this way, the atomized liquid is sealed in the liquid storage tank.

[0003] However, when the atomizing matrix fills the liquid storage tank and the cigarette holder is assembled, as the cigarette holder is inserted, the air pressure in the liquid storage tank increases, which will compress the atomizing liquid, and in severe cases, leakage from the heating module end will occur. Summary of the invention

[0004] In a first aspect of the present disclosure, an atomizing device is provided. The atomizing device comprises: a housing, comprising: a liquid storage tank for accommodating an atomizing matrix, the liquid storage tank having an injection hole, and the atomizing matrix is ​​added to the liquid storage tank via the injection hole; a convex rib portion protruding circumferentially from a first side of a hole wall of the injection hole in a radial direction; and at least one air release groove, each arranged to axially penetrate the convex rib portion; and a support member, arranged to close the injection hole, and comprising: an annular protrusion, arranged to be tightly matched with a second side of the hole wall of the injection hole in a radial direction to at least seal the injection hole; and at least one air release groove, each extending axially from a free end of the support member to the annular protrusion.

[0005] In some embodiments, the first side is an outer side of a hole wall of the injection hole, and the second side is an inner side of the hole wall of the injection hole.

[0006] In some embodiments, the number of the at least one air relief groove or the at least one air exhaust groove is 1-3.

[0007] In some embodiments, the cross-section of the rib portion is arc-shaped.

[0008] In some embodiments, the annular protrusion is arranged to be located near the end of the housing where the injection hole is provided after the support member is installed in place.

[0009] In some embodiments, at least one exhaust slot extends in a direction parallel to the axis of the housing, extends at a non-zero angle to the axis of the housing, or extends in a spiral shape.

[0010] In some embodiments, the atomization device also includes: a central tube extending from the center of the liquid storage tank along the axial direction of the shell, so as to limit the cross-sectional shape of the liquid storage tank to a ring shape together with the shell, the central tube is suitable for allowing the atomized atomized matrix to pass through, and the support member also includes an inner hole, which is sealingly coupled to the central tube.

[0011] In some embodiments, the atomizing device further comprises: a sealing ring arranged in a sealing groove of the inner hole of the support member to sealingly surround the central tube.

[0012] In some embodiments, the atomizing device further comprises: a suction nozzle coupled to the support and comprising a suction channel axially aligned with the central tube.

[0013] In some embodiments, the suction nozzle includes: an inner coupling portion, which at least partially defines the suction channel and is tightly fitted to the inner hole of the support; and an outer coupling portion, which is circumferentially arranged outside the inner coupling portion and coupled to the periphery of the outer side wall of the injection hole.

[0014] In some embodiments, the outer coupling portion includes: an annular groove arranged to be aligned with the rib portion in a radial direction after the support member is installed in place, and having a cross-sectional shape matching the rib portion.

[0015] By providing an air leakage groove on the side wall of the liquid injection hole of the liquid storage bin, and providing an exhaust groove on the support member, when the suction nozzle is coupled to the housing and the support member is coupled to the side wall of the liquid injection hole, the support member squeezes the air inside the liquid storage bin and the atomized matrix, and at this time, the air inside the liquid storage bin is led out of the liquid storage bin through the air leakage groove and the exhaust groove, so that the air pressure inside and outside the liquid storage bin is balanced, thereby reducing the leakage of the atomized matrix from the liquid storage bin due to excessive pressure inside the liquid storage bin when the support member is blocking the liquid injection hole.

[0016] In a second aspect of the present disclosure, an atomization device is provided, which includes: a power source; and an atomization device provided according to the first aspect of the present disclosure, wherein the atomization device is coupled to the power source.

[0026] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

[0027] It should be noted that the titles of any sections / subsections provided herein are not restrictive. Various embodiments are described throughout this article, and any type of embodiment may be included under any section / subsection. In addition, the embodiments described in any section / subsection may be combined in any manner with any other embodiments described in the same section / subsection and / or different sections / subsections.

[0028] In the description of the embodiments of the present disclosure, the term "including" and similar terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". Other explicit and implicit definitions may be included below. The terms "first", "second", etc. may refer to different or the same objects. Other explicit and implicit definitions may be included below.

[0029] As briefly mentioned above, when the mouthpiece (also called the suction nozzle) is inserted into the end of the liquid storage chamber of the atomizer device to close the liquid storage chamber (for example, after the liquid storage chamber is filled with atomized matrix), as the mouthpiece is continuously inserted, the space formed by the liquid storage chamber and the mouthpiece is continuously reduced and the internal air is compressed, thereby causing the pressure in the liquid storage chamber to rise. In this case, the atomized matrix is ​​easy to overflow from the other end of the liquid storage chamber (for example, one end of the heating module).

[0030] The embodiments of the present disclosure propose an atomization device and an atomization equipment to solve or at least partially solve the above-mentioned problems and other potential problems existing in the traditional solutions. Various embodiments of the present disclosure provide an air leakage groove on the side wall of the injection hole of the liquid storage tank of the shell, and provide an exhaust groove on the support member (which may be a part of the suction nozzle or coupled to the suction nozzle) for blocking the injection hole. In this way, during the period when the support member is coupled to the side wall of the injection hole, the support member squeezes the air inside the liquid storage tank and the atomized matrix. At this time, the air inside the liquid storage tank is guided to the outside of the liquid storage tank through the air leakage groove and the exhaust groove, so that the air pressure inside and outside the liquid storage tank is balanced, thereby reducing the leakage of the atomized matrix from the liquid storage tank due to excessive pressure inside the liquid storage tank during the period when the support member blocks the injection hole.

[0031] Figure 1 The overall structure diagram of the atomizing device of the embodiment of the present disclosure is shown. Figure 1 As shown, the atomization device of the embodiment of the present disclosure includes a power supply and an atomization device. The power supply is used to supply power to at least a heating module (also known as an atomization core or a heating core) in the atomization device. The heating module heats the atomization matrix during operation to convert the atomization matrix into an aerosol. In some embodiments, the power supply can be a rechargeable battery. In some alternative embodiments, the power supply can also be a power supply module connected to the mains, etc.

[0032] Figures 2 to 4 The cross-sectional views of the atomizer in different assembly states are shown respectively. Figures 2 to 4 As shown, the atomizing device generally includes a housing 1 and a support member 2 coupled to the housing 1. The housing 1 includes a liquid storage tank 11 for storing atomized substrates, and a liquid injection hole 12 is provided at one end of the liquid storage tank 11 or at the end of the housing 1. The user can fill the atomized substrate into the liquid storage tank 11 through the liquid injection hole 12. When the atomized substrate in the liquid storage tank 11 is filled, the support member 2 can be coupled to the liquid injection hole 12 along the installation direction I and close the liquid injection hole 12.

[0033] like Figures 2 to 4 As shown, specifically, the support member 2 closes the injection hole 12 including the following process: the support member 2 moves along the installation direction I from an idle position separated from the housing 1 to a pre-tightened position partially coupled with the injection hole 12. Then, the support member 2 continues to move along the installation direction I to an installation position fully coupled with the injection hole 12 and closes the injection hole 12.

[0034] In some embodiments, the cross-section of the support member 2 may be annular, and the outer diameter of the support member 2 may be equal to or slightly larger than the inner diameter of the injection hole 12, so that the support member 2 may be inserted into the injection hole 12, and the injection hole 12 may be closed and sealed by a tight fit between the outer wall of the support member 2 and the inner side surface of the hole wall of the injection hole 12 (that is, the radial inner side of the end of the shell 1 where the injection hole 12 is provided). In other embodiments, the inner diameter of the support member 2 may also be equal to or slightly smaller than the outer diameter of the injection hole 12, so that the support member 2 may be sleeved on the outside of the injection hole 12, that is, sleeved on the outside of the end of the shell 1 where the injection hole 12 is provided, so that the injection hole 12 may be closed by a tight fit between the inner wall of the support member 2 and the outer side surface of the hole wall of the injection hole 12.

[0035] It should be understood that according to the embodiment of the present disclosure, whether the support member 2 is inserted into the injection hole 12 or sleeved outside the injection hole 12, the support member 2 can be coupled with the injection hole 12, and these two connection methods are similar in principle and effect of blocking the injection hole 12. The following description will be mainly based on the example structure in which the support member 2 is inserted into the injection hole 12 shown in the figure, but the form in which the support member 2 is sleeved outside the injection hole 12 is also applicable.

[0036] like Figures 2 to 4 As shown, in some embodiments, the atomizing device further includes a nozzle 5 coupled to the support member 2. The nozzle 5 includes a suction portion, an inner coupling portion 52 coupled to the support member 2, and an outer coupling portion 51 coupled to the outer side of the hole wall of the injection hole 12 (that is, the radial outer side of the end of the shell 1 where the injection hole 12 is set). The suction portion is suitable for coupling with the user's mouth for the user to inhale, and has a shape and structure suitable for coupling with the user's mouth. For example, the cross-sectional shape of the suction portion can be any appropriate shape such as an ellipse, a circle, etc., and the embodiments of the present disclosure are not limited to this. A through suction channel is formed in the nozzle 5, and the suction channel can be connected to the aerosol airflow generated by the heating module, so that when the user inhales at the suction portion, the aerosol can flow into the user's body through the suction channel.

[0037] The inner coupling part 52 and the outer coupling part 51 are arranged at an end of the nozzle 5 opposite to the suction part in the axial direction. The inner coupling part 52 is arranged radially inside the outer coupling part 51 and is cylindrical, and at least partially forms a suction passage.

[0038] In some embodiments, the inner coupling portion 52 of the suction nozzle 5 is coupled to the support member 2. For example, the support member 2 further includes an inner hole 23. The inner hole 23 is arranged through the support member 2 along the axial direction of the support member 2. The suction nozzle 5 and the support member 2 may be formed separately, and the inner coupling portion 52 of the suction nozzle 5 is tightly fitted in the inner hole 23 of the support member 2 to thereby couple the suction nozzle 5 and the support member 2 together. In some alternative embodiments, the suction nozzle 5 may also be integrally formed with the support member 2.

[0039] When the support member 2 is coupled to the injection hole 12, the outer coupling portion 51 of the suction nozzle 5 is sleeved on the outer side surface (hereinafter referred to as the first side) of the hole wall of the injection hole 12. On the first side of the hole wall of the injection hole, a convex rib portion 13 is provided. The convex rib portion 13 protrudes from the first side (i.e., the outer side) of the hole wall in the circumferential direction. In some embodiments, correspondingly, an annular groove 511 is also provided on the outer coupling portion 51. The annular groove 511 is recessedly arranged on the surface of the outer coupling portion 51 in the radial direction. When the support member 2 is inserted into the injection hole 12 and reaches the installation position relative to the injection hole 12, the outer coupling portion 51 of the suction nozzle 5 is sleeved on the outer side wall of the injection hole 12 (i.e., the suction nozzle 5 is installed in place), the annular groove 511 is aligned with the convex rib portion 13 in the radial direction, and the convex rib portion 13 is embedded in the annular groove 511, thereby realizing reliable positioning and limiting of the suction nozzle 5 and the support member 2 on the housing 1.

[0040] The housing 1 also includes at least one air relief groove 14. The air relief groove 14 is provided on the rib portion 13, and the air relief groove 14 is arranged to penetrate the rib portion 13 along the axis. With the aid of the exhaust groove to be mentioned later, when the support member 2 moves from the idle position to the pre-tightened position along the installation direction I, the gas in the liquid storage tank 11 can be discharged to the outside of the liquid storage tank 11 through the exhaust groove 22 and the air relief groove 14 in sequence, thereby achieving pressure balance of the liquid storage tank 11 and effectively preventing leakage of the atomized matrix in the liquid storage tank 11 due to excessive pressure. In some embodiments, when a plurality of air relief grooves 14 can be arranged on the rib portion 13 (for example, two or three air relief grooves 14 are arranged on the rib portion 13), the plurality of air relief grooves 14 can be arranged continuously or at intervals on the rib portion 13 along the circumferential direction.

[0041] Figure 5 FIG. 2 shows an exploded view of the support member and the housing of the embodiment of the present disclosure. Figure 5As shown, in some embodiments, the support member 2 includes an annular protrusion 21. The annular protrusion 21 is protrudingly disposed on the outer peripheral surface of the support member 2 along the radial direction of the support member 2, and the annular protrusion 21 is coaxial with the support member 2. When the support member 2 moves from the idle position to the pre-tightening position along the installation direction I, the annular protrusion 21 gradually approaches the radial inner side surface (hereinafter referred to as the second side) of the hole wall of the injection hole 12. After the support member 2 continues to move from the pre-tightening position to the installation position along the installation direction I, the annular protrusion 21 is pressed against the second side of the hole wall of the injection hole 12, thereby achieving sealing between the support member 2 and the injection hole 12.

[0042] In some embodiments, the outer diameter of the annular protrusion 21 can be slightly larger than the inner diameter of the hole wall of the injection hole 12, while the outer diameter of other parts of the support member 2 can be equal to or slightly smaller than the inner diameter of the hole wall of the injection hole 12, thereby facilitating the movement of the support member 2 from the pre-tightening position to the installation position.

[0043] In addition, the annular protrusion 21 can be arranged to be located near the end of the housing 1 where the injection hole 12 is set, that is, near the orifice of the injection hole 12 when the support member 2 is in the installation position. In other words, the annular protrusion 21 just contacts and abuts against the inner side of the hole wall of the injection hole 12, and the assembly between the two is completed. In this way, it is beneficial to effectively release the pressure of the air in the liquid storage tank 11. In some embodiments, the cross-sectional shape of the annular protrusion 21 can be arranged as an arc, so as to facilitate the tight fit with the hole wall of the injection hole 12.

[0044] As mentioned above, the support member 2 further includes at least one exhaust groove 22 arranged on the annular protrusion 21 and located on one side of the injection hole 12 in the axial direction. In some embodiments, the extension direction of the exhaust groove 22 can be parallel to the axial direction of the support member 2, and the exhaust groove 22 can extend from the free end of the support member 2 to the annular protrusion 21, that is, the end of the exhaust groove 22 facing the annular protrusion 21 is close to the annular protrusion 21 or flush with the annular protrusion 21.

[0045] Of course, it should be understood that the structure of the exhaust groove 22 is not limited to this, and it may also have other structures or extension directions. For example, in some alternative embodiments, the exhaust groove 22 may also extend obliquely (that is, at a non-zero angle with the axis of the housing 2) or extend in a spiral shape. The following will mainly take the exhaust groove 22 extending in a direction parallel to the axis of the housing 2 as an example to describe the concept according to the present disclosure. It should be understood that the situation where the exhaust groove 22 has other structures or extension directions is also similar, and will not be described separately in the following.

[0046] When the support member 2 moves from the idle position to the installation position via the pre-tightening position along the installation direction I, as the support member 2 moves, the air inside the liquid storage tank 11 is discharged to the outside of the liquid storage tank 11 through the pores formed by the exhaust groove 22 and the second side (i.e., the inner side) of the hole wall of the liquid injection hole 12, and through the gap between the air discharge groove 14 and the external coupling part 51, thereby balancing the air pressure inside and outside the liquid storage tank 11 and reducing the problem of leakage of the atomized matrix due to excessive pressure inside the liquid storage tank 11.

[0047] During the movement of the support member 2 from the pre-tightening position to the installation position, the rib portion 13 of the shell 1 moves into the annular groove 511 of the external coupling portion 51, and at the same time the annular protrusion 21 presses against the second side of the hole wall of the injection hole 12 (i.e., forming a tight fit), so that the support member 2 is sealed with the inner wall of the injection hole 12, and the atomized matrix is ​​enclosed in the liquid storage tank 11.

[0048] Figure 6 and Figure 7 Some embodiments of the present disclosure are respectively shown in Figure 1 A cross-sectional view along line BB from the perspective of Figure 6 In the example shown, the number of the exhaust groove 22 and the exhaust groove 14 is one. Figure 7 In the example shown, the number of the exhaust grooves and the air relief grooves 14 is two. Of course, it should be understood that the embodiments of the present disclosure are not limited thereto, and like the air relief grooves 14 mentioned above, the exhaust grooves 22 may also have other numbers (e.g., three), and a plurality of exhaust grooves 22 may be distributed on the support member 2 along the circumference of the support member 2.

[0049] In some embodiments, the number of the exhaust slots 22 may be equal to or unequal to the number of the air relief slots 14. In addition, the positions of the exhaust slots 22 may be aligned with the positions of the air relief slots 14 in the radial direction, or may not be aligned, which is not limited in the embodiments of the present disclosure.

[0050] In addition, for the support member 2 mentioned above, which is sleeved on the outside of the injection hole 12, the annular protrusion 21 and the exhaust groove 22 can be arranged on the inner wall of the support member 2. Accordingly, when the support member 2 moves from the idle position to the pre-tightening position along the installation direction I, the air in the liquid storage tank 11 can be discharged to the outside of the liquid storage tank 11 through the gap between the exhaust groove 22 and the outer side surface of the hole wall of the injection hole 12 (hereinafter referred to as the first side) and through the gap between the exhaust groove 14 and the external coupling part 51. As the support member 2 moves from the pre-tightening position to the installation position along the installation direction I, the annular protrusion 21 gradually abuts against the outer side of the hole wall of the injection hole 12, that is, abuts against the outer side of the end of the shell 1 where the injection hole 12 is set, so that the support member 2 closes and seals the injection hole 12.

[0051] In some embodiments, the atomizing device further comprises a central tube 3, which is arranged in the housing 1 and the axis of the central tube 3 coincides with the axis of the housing 1. Of course, it should be understood that the embodiments of the present disclosure are not limited thereto. For example, in some alternative embodiments, the axis of the central tube 3 may also deviate from the axis of the housing 1. One end of the central tube 3 is connected to the airflow of the heating module of the atomizing device, and the other end is coupled to at least one of the nozzle 5 and the support 2, and the suction channel on the nozzle 5 is aligned with the central tube 3 on the axis. When the nozzle 5 is coupled to the end of the injection hole 12, the central tube 3 is connected to the suction channel, so that under the action of the user's suction, the aerosol formed after the atomized matrix is ​​heated by the heating module can be circulated to the nozzle 5 through the central tube 3 and discharged from the other end of the nozzle 5. The central tube 3 at least partially passes through the liquid storage tank 11, so that the cross-sectional shape of the space for storing the atomized matrix in the liquid storage tank 11 is further limited to a ring.

[0052] In some embodiments, the inner hole 23 of the support member 2 is sealed with the side wall of the central tube 3. Specifically, the support member 2 includes a sealing groove 24 provided on the circumference of the inner hole 23, and a sealing ring 4 is embedded in the sealing groove 24. When the support member 2 is coupled to the injection hole 12, the sealing ring 4 abuts against the circumference of the central tube 3, thereby achieving sealing at the connection between the support member 2 and the central tube 3.

[0053] The above descriptions of various implementations of the present disclosure are exemplary, non-exhaustive, and not limited to the disclosed implementations. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described implementations. The selection of terms used herein is intended to best explain the principles of the implementations, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the various implementations disclosed herein.
