Description

Technical Field

[0001] The present application relates to the technical field of atomization, and particularly to a liquid storage component and an atomization device. Background Art

[0002] An aerosol is a colloidal dispersion system formed by solid or liquid small particles dispersed and suspended in a gas medium. Since an aerosol can be absorbed by the human body through the respiratory system, it provides a new alternative absorption method for users. An atomization device refers to a device that forms an aerosol by heating or ultrasonic means on a storable atomizable medium. The atomizable medium includes a liquid, a gel, a paste, or a solid aerosol generation matrix. Atomizing these media can deliver an inhalable aerosol to the user, replacing the conventional product form and absorption method.

[0003] An atomization device with a liquid as the atomization medium usually has a liquid storage cavity for storing the atomization medium. However, due to the volume of the atomization device and other factors, the capacity of the liquid storage cavity is limited, which limits the usage time of the atomization device. Moreover, the greater the liquid injection volume of the atomization device, the higher the risk of liquid leakage and loss of aromatic substances during storage and transportation, thus bringing many inconveniences to users. Summary of the Invention

[0004] Based on this, it is necessary to provide an atomization component and an atomization device for the problem of the limited capacity of the liquid storage cavity of the atomization device.

[0005] A liquid storage component, the liquid storage component includes:

[0006] A housing having a liquid storage cavity;

[0007] A cover body that closes the liquid storage cavity, and the cover body has a liquid outlet hole communicating with the liquid storage cavity. The liquid outlet hole penetrates through the relatively arranged first surface and second surface, and the first surface faces the liquid storage cavity;

[0008] A seal, at least partially abuts against the second surface and closes the liquid outlet hole.

[0009] In one embodiment, the cover body further has a receiving hole communicating with the liquid outlet hole, and at least part of the seal is received in the receiving hole.

[0010] In one embodiment, the housing further has a supporting portion, the supporting portion is connected to the housing and is located at an end of the liquid outlet hole away from the liquid storage cavity, and the seal is supported on the supporting portion.

[0011] In one embodiment, the seal includes a main body and a sealing portion. The main body abuts against the second surface, and the sealing portion closes the liquid outlet hole. Along the direction from the first surface to the second surface, at least a part of the thickness of the connection between the main body and the sealing portion is less than the thickness of the main body.

[0012] In one embodiment, the connection between the main body and the sealing portion includes a thinning portion and a thickening portion. The thinning portion has an annular structure with separated head and tail, and the thickness of the thickening portion is greater than that of the thinning portion and is connected between the head and tail ends of the thinning portion.

[0013] In one embodiment, along the direction from the second surface to the first surface, the projection of the sealing portion is within the liquid outlet hole.

[0014] An atomizing device includes a power supply assembly, an atomizing assembly, and the above-mentioned liquid storage assembly.

[0015] In one embodiment, the atomizing assembly is detachably connected to the liquid storage assembly and the power supply assembly respectively.

[0016] In one embodiment, the atomizing assembly is provided with a piercing member. When the liquid storage assembly is installed on the atomizing assembly, the piercing member pierces the seal.

[0017] In one embodiment, the piercing member is provided with a liquid inlet channel for communicating with the liquid storage cavity.

[0018] When using the above-mentioned liquid storage assembly, it is necessary to pierce the part of the seal that closes the liquid outlet hole so that the liquid outlet hole is opened. Since the seal abuts against the second surface where the liquid outlet hole is located, when piercing the seal, the second surface provides a force opposite to the piercing force outside the piercing position, thereby restricting the deformation amount of the seal when it is pierced and ensuring smooth piercing of the seal.

[0039] Refer to Figure 1 and Figure 2 An embodiment of the present application provides an atomizing device 100 for heating an atomizing medium to generate an aerosol for user use. The atomizing medium includes, but is not limited to, liquid medicines and oils of materials for medical, health preservation, health, and beauty purposes.

[0040] The atomizing device 100 includes a power supply assembly 20, an atomizing assembly 40, and a liquid storage assembly 60. The power supply assembly 20 is detachably electrically connected to the atomizing assembly 40. The atomizing assembly 40 stores the atomizing medium, and the atomizing assembly 40 can heat the atomizing medium under the action of the electric energy of the power supply assembly 20 to generate an aerosol. The liquid storage assembly 60 is detachably connected to the atomizing assembly 40 for replenishing the atomizing medium for the atomizing assembly 40, and after the atomizing medium in the liquid storage assembly 60 is exhausted, a new liquid storage assembly 60 can be replaced to continue replenishing the atomizing assembly 40 with liquid.

[0041] Please refer to Figure 3 The power supply assembly 20 includes a housing 21, a battery holder 23, a spring pin 25, and a battery 27. The housing 21 is generally in a hollow shell structure. In the following embodiments, the height direction of the housing 21 is defined as the first direction (i.e., Figure 1 the Z direction in Figure 1 ), the length direction of the housing 21 is defined as the second direction (i.e., Figure 1 the X direction in Figure 1 ), and the width direction of the housing 21 is defined as the third direction (i.e., Figure 1 the Y direction in Figure 1 ). It can be understood that the shape of the housing 21 is not limited to this and can be set as needed to meet different requirements.

[0042] Please refer to Figure 3 and Figure 4 As shown, the battery bracket 23 is received in the housing 21 and includes a first bracket 232 and a second bracket 234 that are connected to each other. The first bracket 232 is located at one end of the housing 21 in the first direction. One end of the second bracket 234 is connected to one side of the first bracket 232 in the second direction, and the other end of the second bracket 234 extends along the first direction to the other end of the housing 21 away from the first bracket 232, thereby dividing the housing 21 into a first accommodation cavity and a second accommodation cavity that are adjacent to each other in the second direction. And an opening communicating the first accommodation cavity with the external atmosphere is provided at one end of the housing 21 away from the first bracket 232 in the first direction. The first accommodation cavity is used for installing the atomization component 40 and the liquid storage component 60, and the second accommodation cavity is used for receiving the battery 27. The spring pin 25 is installed on the first bracket 232 and is used for electrically connecting the atomization component 40 and the battery 27.

[0043] Please refer to Figure 3 and Figure 5 as well as Figure 6 . The atomization component 40 is received in the first accommodation cavity and is located on one side of the first bracket 232 in the first direction. The atomization component 40 includes a housing 41, an atomization base 43, a top pin 45, an atomization core 47, and a liquid storage body 49.

[0044] The housing 41 has a hollow housing structure and includes an annular sleeve 412 and a partition plate 414. The central axis of the annular sleeve 412 extends along the first direction. The partition plate 414 is provided inside one end of the annular sleeve 412 away from the first bracket 232. The side of the partition plate 414 facing the first bracket 232 and the annular sleeve 412 together form an accommodation space for accommodating the atomization core 47 and the liquid storage body 49, and the side of the partition plate 414 facing away from the first bracket 232 and the annular sleeve 412 together form an installation groove for installing the liquid storage component 60.

[0045] The atomization base 43 includes a heating base 432, a heating base seal 434, and a liquid absorption cotton 436. The heating base 432 is fitted to one end of the annular sleeve 412 facing the first bracket 232. The heating base seal 434 is fitted to the side of the heating base 432 facing the partition plate 414. The liquid absorption cotton 436 is filled between the heating base 432 and the heating base seal 434 and is used for absorbing condensate. The top pin 45 is installed on the heating base 432, and one end face of the top pin 45 contacts the spring pin 25 of the power supply component 20 to electrically connect with the power supply component 20.

[0046] The atomizing core 47 includes a heating element 476, a liquid guide 474, and an atomizing tube 472. The heating element 476 is in a cylindrical structure formed by winding a metal material such as a heating mesh or a heating wire around a first direction, and the heating element 476 is electrically connected to the thimble 45 through a wire. The liquid guide 474 is circumferentially coated outside the heating element 476, the atomizing tube 472 is sleeved outside the liquid guide 474, one end of the atomizing tube 472 is inserted into the heating seat seal 434 of the atomizing base 43 along the first direction, and the other end of the atomizing tube 472 is inserted into the partition plate 414 of the housing 41 along the first direction. An air flow channel 47a extending along the first direction is formed inside the atomizing core 47, and a main liquid storage cavity surrounding the atomizing core 47 circumferentially is formed between the atomizing core 47 and the housing 41. The liquid storage member 49 is received in the main liquid storage cavity and circumferentially coats outside the atomizing core 47. Thus, the main liquid storage cavity is used to store the atomizing medium and introduce the atomizing medium into the atomizing core 47. The liquid guide 474 of the atomizing core 47 can guide the atomizing medium to the surface of the heating element 476, and the heating element 476 can heat the atomizing medium under the action of the electric energy of the power supply assembly 20 to generate aerosol.

[0047] As Figure 4 and Figure 5 shown, in some embodiments, the first bracket 232 of the battery bracket 23 is further provided with a first magnetic member 29, and the heating seat 432 of the atomizing assembly 40 is provided with a second magnetic member 438. The first magnetic member 29 and the second magnetic member 438 can be mutually adsorbed to fixedly connect the battery bracket 23 and the atomizing assembly 40. It can be understood that the fixing manner of the battery bracket 23 and the atomizing assembly 40 is not limited to this, and can be set as needed to meet different requirements.

[0048] Please refer to Figure 6 and Figure 7 , in some embodiments, an exhaust hole 414a communicating with the air flow channel 47a of the atomizing core 47 is opened at the central position of the partition plate 414 of the housing 41, and the aerosol in the air flow channel 47a can flow out through the exhaust hole 414a. Two piercing members 416 protrude from the side of the partition plate 414 facing away from the main liquid storage cavity. The two piercing members 416 are respectively located on opposite sides of the exhaust hole 414a in a second direction. Each piercing member 416 is provided with a liquid inlet channel 416a communicating with the main liquid storage cavity through a first direction. The piercing member 416 is used to pierce the liquid storage assembly 60 and introduce the atomizing medium in the liquid storage assembly 60 into the main liquid storage cavity.

[0049] As a preferred embodiment, the end face of each piercing member 416 away from the partition plate 414 extends obliquely, and the height of the piercing member 416 gradually decreases from the side away from the exhaust hole 414a to the side close to the exhaust hole 414a, so as to facilitate piercing the liquid storage assembly 60. It can be understood that the number and position of the piercing members 416 are not limited to this, and the piercing members 416 can be one or more.

[0050] It can be understood that the piercing of the liquid storage component 60 includes the way of piercing, and also includes other ways of separating the local structure from the main structure. In the following embodiments, the piercing member 416 conducts the main liquid storage cavity by piercing the liquid storage component 60.

[0051] As Figure 6 , Figure 7 , Figure 9 , Figure 10 and Figure 11 shown, one end of the liquid storage component 60 is received in the first accommodation cavity of the power supply component 20, and the other end of the liquid storage component 60 passes through the communication port of the housing 21 and extends out of the first accommodation cavity. The liquid storage component 60 includes a housing 61, a cover 62 and a seal 63. The housing 61 has a liquid storage cavity 61a with one end open. The cover 62 is connected to the housing 61 and closes the open end of the liquid storage cavity 61a. The cover 62 has a liquid discharge hole 62a communicating with the liquid storage cavity 61a. The liquid discharge hole 62a penetrates through the first surface 621 and the second surface 623 of the cover 62 arranged oppositely in the first direction. The seal 63 at least partially abuts against the second surface and closes the liquid discharge hole 62a.

[0052] Thus, when using the above-mentioned liquid storage component 60, the part of the seal 63 that closes the liquid discharge hole 62a needs to be pierced so that the liquid discharge hole 62a is opened. Since the seal 63 abuts against the second surface 623 where the liquid discharge hole 62a is located, when piercing the seal 63, the second surface 623 provides a force opposite to the piercing force outside the piercing position, thereby restricting the deformation amount of the seal 63 when being pierced and ensuring the smooth piercing of the seal 63.

[0053] Specifically, the housing 61 includes an outer ring housing 612 and a central tube 616. The outer ring housing 612 has a hollow structure with one end open. The open end of the outer ring housing 612 is connected to the atomization component 40. The central axis of the outer ring housing 612 extends in the first direction. The cover 62 is installed at the open end of the outer ring housing 612. One end of the central tube 616 is connected to the closed end of the outer ring housing 612, and the other end extends along the first direction to the open end of the outer ring housing 612 and passes through the cover 62 and is inserted into the exhaust hole 414a of the partition plate 414 of the housing 41. An air outlet channel 616a extending in the first direction is formed in the central tube 616. One end of the air outlet channel 616a penetrates through the closed end of the outer ring housing 612 to communicate with the external atmosphere, and the other end of the air outlet channel 616a communicates with the exhaust hole 414a of the partition plate 414. A liquid storage cavity 61a surrounding the air outlet channel 616a in the circumferential direction is formed between the housing 21, the central tube 616 and the cover 62.

[0054] Corresponding to the number and position of the piercing member 416 of the atomizing assembly 40, the cover body 62 is provided with two lower liquid holes 62a, and the two lower liquid holes 62a are arranged at intervals in the first direction. It can be understood that the number and the arrangement position of the lower liquid holes 62a are not limited thereto, and the cover body 62 may have only one lower liquid hole 62a, or may have multiple lower liquid holes 62a, and the number of the lower liquid holes 62a is the same as the number of the piercing member 416 of the atomizing assembly 40.

[0055] In some embodiments, the second surface 623 of the cover 62 abuts against more than 70% of the edge area of ​​one side surface of the seal 63 to provide a good support effect. As a preferred embodiment, the second surface 623 of the cover 62 abuts against the entire edge area of ​​one side surface of the seal 63, thereby providing a better support effect. It can be understood that in some other embodiments, the second surface 623 can abut against different areas of the seal 63 to meet different support requirements.

[0056] In some embodiments, the cover body 62 further has a receiving hole 62b that is connected to and coaxially arranged with the lower liquid hole 62a, the receiving hole 62b is connected to the second surface 623 and the aperture of the receiving hole 62b is larger than the aperture of the lower liquid hole 62a, and at least part of the sealing member 63 is received in the receiving hole 62b. In some other embodiments, the receiving hole 62b may not be provided, and the sealing member 63 is attached to the second surface 623 and partially extends into the lower liquid hole 62a.

[0057] In some embodiments, the housing 61 is further provided with a resisting portion 67b, which is matched with the housing 61 and located at one end of the lower liquid hole 62a away from the liquid storage chamber 61a, and the sealing member 63 is supported on the resisting portion 67. In this way, when the liquid storage assembly 60 is separated from the atomizing assembly 40, the sealing member 63 is resisted by the resisting portion 67b, thereby effectively preventing the sealing member 63 from following the piercing member 416 of the atomizing assembly 40 and detaching from the lower liquid hole 62a.

[0058] Specifically in some embodiments, the liquid storage component 60 also includes a wrapping member 67, which is formed of a material with relatively high strength such as ordinary grade cold-rolled steel plate. The wrapping member 67 is a cylindrical structure with one end open, including a bottom plate 672 and a side plate 674 extending from the edge of the bottom plate 672 in the same direction. The bottom plate 672 is connected to an end surface of the shell 61 where a lower liquid hole 62a is opened, and the side plate 674 is mounted on the outside of the shell 61, and a supporting portion 67b is formed on the bottom plate 672.

[0059] More specifically, an avoidance hole 67a communicating with the lower liquid hole 62a is formed in the bottom plate 672 of the package 67. At least a part of the edge of the avoidance hole 67a protrudes from the hole wall of the lower liquid hole 62a, and a holding portion 67b for holding the seal 63 is constructed. Further, the holding portion 67b holds more than 70% of the edge area of one side surface of the seal 63, so as to achieve a good blocking effect. As a preferred embodiment, the aperture of the avoidance hole 67a is larger than that of the lower liquid hole 62a, the entire edge of the avoidance hole 67a protrudes from the hole wall of the lower liquid hole 62a, and the holding portion 67b holds the entire edge area of the seal 63. In some other embodiments, the shape of the holding portion 67b is not limited to this, and can be set as needed to meet different blocking requirements.

[0060] The liquid storage assembly 60 includes two seals 63, including a main body 632 and a sealing portion 634. The sealing portion 634 has a disc-shaped structure, and in the direction from the second surface 623 to the first surface 621 of the cover body 62 (i.e., the first direction), the projection of the sealing portion 634 is within the lower liquid hole 62a. The main body 632 is a hollow cylindrical structure surrounding the sealing portion 634 in the circumferential direction. The main body 632 abuts against the second surface 623 of the cover body 62, the sealing portion 634 closes the lower liquid hole 62a, and in the direction from the first surface 621 to the second surface 623, the thickness of at least a part of the connection between the main body 632 and the sealing portion 634 is smaller than the thickness of the main body 632. Therefore, the connection strength at the connection between the main body 632 and the sealing portion 634 is relatively small, and the sealing portion 634 can be separated from the main body 632 under the abutment of the piercing member 416. The atomizing medium in the liquid storage cavity 61a can enter the liquid inlet channel 416a of the piercing member 416 and then flow into the liquid storage body 49 in the main liquid storage cavity.

[0061] As a preferred embodiment, when the piercing member 416 passes through the seal 63 and extends into the cover body 62, the main body 632 is in interference fit with the piercing member 416 and the cover body 62 respectively, so as to prevent the atomizing medium from flowing out through the gap between the three. Specifically, in one embodiment, a circumferentially extending rib is convexly provided on the outer side wall of the main body 632, so as to achieve a good sealing effect.

[0062] Please refer to Figure 6 、 Figure 7 and Figure 12 As shown, in some embodiments, the connection between the main body 632 and the sealing portion 634 includes a thinning portion 6341 and a thickening portion 6343. The thinning portion 6341 has an annular structure separated at the head and tail, and the thickness of the thickening portion 6343 is greater than that of the thinning portion 6341 and is connected between the head and tail ends of the thinning portion 6341.

[0063] Thus, when the liquid storage assembly 60 is installed on the atomization assembly 40, only the thinning portion 6341 of the sealing portion 634 ruptures, causing the sealing portion 634 to be partially separated from the main body 632, while the thickening portion 6343 remains connected to the main body 632. Therefore, the sealing portion 634 has a certain reset ability when the liquid storage assembly 60 is separated from the atomization assembly 40. When the piercing member 416 disengages from the liquid outlet hole 62a, the sealing portion 634 can re-seal the main body 632 under the gravity of the atomization medium in the liquid storage chamber 61a, thereby preventing the occurrence of catastrophic liquid leakage.

[0064] In some embodiments, the liquid storage assembly 60 further includes a liquid outlet connecting member 65. The liquid outlet connecting member 65 is located between the cover 62 and the wrapping member 67. Two sealing members 63 protrude from one side surface of the liquid outlet connecting member 65 and are integrally formed with the liquid outlet connecting member 65. In this way, the two sealing members 63 are integrated into a whole through the liquid outlet connecting member 65, thereby reducing the number of parts of the liquid storage assembly 60 and improving the assembly efficiency of the liquid storage assembly 60.

[0065] Please refer back to Figure 6 、 Figure 7 and Figure 11 In some embodiments, the liquid storage assembly 60 further includes a cover seal 69. The cover seal 69 is fitted to the cover 62 and is used to seal the gaps between the cover 62 and the outer ring housing 612, and between the cover 62 and the central tube 616, thereby maintaining the negative pressure state in the liquid storage chamber 61a and preventing the atomization medium from entering the central tube 616.

[0066] Specifically, the cover seal 69 covers the side facing the liquid storage chamber 61a. An airway sealing portion 692 protrudes from the central position of the cover seal 69. The airway sealing portion 692 is inserted around the central tube 616 along the circumferential direction at one end of the cover 62. One end of the airway sealing portion 692 is located inside the cover 62, and the other end of the airway sealing portion 692 is located in the exhaust hole 414a and is in interference fit with the hole wall of the exhaust hole 414a. In this way, the gap between one end of the central tube 616 connecting the exhaust hole 414a and the hole wall of the exhaust hole 414a is sealed by the airway sealing portion 692, thereby preventing the atomization medium from leaking through the central tube 616. As a preferred embodiment, at least one circumferentially extending annular rib protrudes from one end of the airway sealing portion 692 located in the exhaust hole 414a, so as to have a good sealing effect.

[0067] In some embodiments, a first buckle 622 protrudes from one end of the cover 62 facing away from the liquid storage chamber 61a, and a second buckle 4142 is provided on the partition plate 414 of the housing 41. The first buckle 622 and the second buckle 4142 can be engaged with each other, thereby realizing the fixed connection between the liquid storage assembly 60 and the atomization assembly 40.

[0068] The above-mentioned liquid storage component 60 and atomization device 100 can replenish the atomization component 40 by replacing the liquid storage component 60, thereby extending the service life of the atomization device 100. At the same time, since the liquid storage component 60 does not have an atomization core 47 for heating, the purchase cost of the liquid storage component 60 is significantly reduced. Moreover, by supporting the sealing part 634 through the cover body 62 and the abutting part 67b, the atomization component 40 can smoothly pierce the liquid storage component 60, ensuring the piercing effect. In addition, since the punctured sealing part 634 has a certain reset ability, it effectively prevents the liquid storage component 60 from leaking when separated from the atomization component 40.

[0069] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0070] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
