Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology, and in particular to an atomizer and an electronic atomization device. Background Technology

[0002] An atomizer is a device that atomizes a matrix into an aerosol. The core component of an atomizer is the atomizing coil. The atomizing coil receives the matrix from the reservoir and heats it to atomize it into an aerosol. Some atomizers in related technologies mount a ceramic atomizing coil on a soft silicone element, theoretically utilizing the deformability of the silicone element to facilitate a sealed installation of the atomizing coil. However, the soft silicone element lacks rigid support, making it prone to displacement and seal collapse, leading to seal failure. Utility Model Content

Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] Please see Figure 1 The illustration shows an electronic atomizing device according to some embodiments of the present invention, which includes a battery assembly and an atomizer. The battery assembly and the atomizer are connected to provide power to the atomizer. When powered on, the atomizer heats an atomizing matrix (e.g., a liquid atomizing matrix) to generate an aerosol for the user to inhale.

[0038] Please see Figures 2 to 5 This illustration shows an atomizer according to some embodiments of the present invention, comprising an atomizing core 3, a first atomizing base 1, and a second atomizing base 2. The atomizing core 3 is connected to a battery assembly 4 and is used to heat an atomizing matrix (e.g., a liquid atomizing matrix) to generate an aerosol for the user to inhale. The atomizing core 3 is mounted on the first atomizing base 1. That is, the first atomizing base 1 serves as the mounting base for the atomizing core 3. The first atomizing base 1 includes a first side surface 11 and at least one first fastening portion 12, the first fastening portion 12 being disposed on the first side surface 11. The second atomizing base 2 includes a second side surface 21 and at least one second fastening portion 22, the second fastening portion 22 being disposed on the second side surface 21. Please refer to [reference needed]. Figures 2 to 10 The XX direction is indicated by the first side 11, which refers to the surface of the first atomizing seat 1 extending along the XX direction; similarly, the second side 21 refers to the surface of the second atomizing seat 2 extending along the XX direction.

[0039] The first fastening part 12 and the second fastening part 22 are adapted to each other, and the first atomizing seat 1 and the second atomizing seat 2 are fastened together through the first fastening part 12 and the second fastening part 22. Furthermore, the first atomizing seat 1 and the second atomizing seat 2 are detachably connected through this fastening connection. During the assembly of the atomizer, the atomizing coil 3 can be installed onto the first atomizing seat 1 first, and then the second atomizing seat 2 can be fastened together with the first atomizing seat 1, facilitating the assembly and disassembly of the first atomizing seat 1 and the second atomizing seat 2. Simultaneously, the second atomizing seat 2 also serves to support the first atomizing seat 1.

[0040] In summary, the atomizing core 3 of the atomizer of this utility model is installed on the first atomizing seat 1, and the first atomizing seat 1 and the second atomizing seat 2 are fastened together by the first fastening part 12 and the second fastening part 22. On the one hand, the second atomizing seat 2 provides support for the first atomizing seat 1, preventing the first atomizing seat 1 from shifting or the sealing boundary from collapsing. On the other hand, it facilitates quick assembly and disassembly between the first atomizing seat 1 and the second atomizing seat 2, which is beneficial to improving the efficiency of parts assembly.

[0041] Specifically, in some embodiments, the stiffness of the first atomizing seat 1 is less than the stiffness of the second atomizing seat 2. Exemplarily, the first atomizing seat 1 can be an elastic or flexible element, such as silicone, rubber, or silicone rubber; the second atomizing seat 2 can be made of a rigid material, such as plastic. Because the first atomizing seat 1 is elastic or flexible, a seal can be achieved between the atomizing core 3 and the first atomizing seat 1 through mutual compression and deformation. The hardness range of the first atomizing seat 1 can be set between 50HA and 80HA (Shore hardness). Preferably, in some embodiments, the hardness of the first atomizing seat 1 can be 60HA (Shore hardness).

[0042] In some embodiments, the first atomizing base 1 can also be used to construct a sealed first liquid storage chamber 5. The first liquid storage chamber 5 is used to store the liquid atomizing matrix. The atomizing core 3 is directly mounted on the first atomizing base 1, thereby eliminating the need for a separate silicone part for mounting the atomizing core 3 while achieving a sealed first liquid storage chamber 5. Specifically, as Figure 4 and Figure 5 As shown, the atomizer also includes a housing 6, which is fitted onto the first atomizing seat 1. The first atomizing seat 1 and the housing 6 are sealed together, and together they define the first liquid storage chamber 5. Specifically, in some embodiments, the outer periphery of the first atomizing seat 1 is provided with at least one raised first sealing rib 13, which contacts the inner wall surface of the housing 6 to achieve a seal between the first atomizing seat 1 and the housing 6. The interference fit between the first sealing rib 13 and the housing 6 can be in the range of 0.2 to 0.3 mm, and the sealing performance must reach 101 kPa in the air pressure test.

[0043] Please see Figures 7 to 11In some embodiments, the first atomizing seat 1 is provided with a mounting hole 14, and the atomizing core 3 is fitted into the mounting hole 14. Specifically, the atomizing core 3 and the mounting hole 14 are interference-fitted to achieve a seal at their assembly boundary. Further, the first atomizing seat 1 also provides a liquid inlet channel 16. The first atomizing seat 1 further includes a top surface 17 facing away from the second atomizing seat 2, through which the liquid inlet channel 16 at least extends. The liquid inlet channel 16 and the mounting hole 14 are in fluid communication. The liquid inlet channel 16 is used to deliver the atomizing matrix to the atomizing core 3, and the liquid in the liquid inlet channel 16 can permeate into the atomizing core 3.

[0044] Specifically, the atomizing core 3 includes a liquid guide 30 and a heating element 31. The liquid guide 30 has an atomizing surface and a liquid inlet surface arranged opposite to each other. The heating element 31 is attached to the atomizing surface and can be partially embedded in the liquid guide 30. The mounting hole 14 can be flexibly designed with reference to the shape and size of the liquid guide 30, but it must meet the sealing interference requirements of the contact boundary between the liquid guide 30 and the mounting hole 14. The sealing interference between the liquid inlet surface of the liquid guide 30 and the mounting hole 14 can be 0.2 to 0.4 mm, and the sealing interference between the side surface of the liquid guide 30 and the mounting hole 14 can be 0 to 0.2 mm. The heating element 31 is connected to the battery assembly 4 through electrode leads. The liquid inlet surface faces the liquid inlet channel 16. The liquid inlet channel 16 is in fluid communication with the first liquid storage chamber 5 and is used to deliver the atomizing matrix to the liquid guide 30. The atomizing matrix in the first liquid storage chamber 5 flows into the liquid 30 through the liquid inlet channel 16. The atomizing matrix gradually permeates from the liquid inlet surface to the atomizing surface and is heated after contacting the heating element 31, thereby generating an aerosol at the atomizing surface.

[0045] like Figure 11 As shown, in some embodiments, the first side surface 11 includes a first outer side surface 111 and a first inner side surface 112. The liquid inlet channel 16 extends along its length direction away from the mounting hole 14, penetrating both the top surface 17 and the first outer side surface 111, forming a notch on the first atomizing seat 1. Alternatively, as... Figure 12 As shown, in some embodiments, the end of the liquid inlet channel 16 away from the mounting hole 14 along its extension length direction only penetrates the top surface 17 and does not penetrate the first outer surface 111. The minimum side length of the liquid inlet channel 16 should not be less than 2.5 mm. Specifically, the first atomizing seat 1 includes a connected top wall and a side wall, which can be integrally formed or separately formed and then connected as one piece. The side wall is annular or arc-shaped, and the two opposite sides of the side wall along its thickness direction are the first outer surface 111 and the first inner surface 112, respectively. The surface of the top wall facing away from the side wall forms the top surface 17. Please refer to... Figures 7 to 10In some embodiments, the atomizer further includes a liquid reservoir 8 disposed within the liquid inlet channel 16. The liquid reservoir 8 may be made of the same material as the liquid guide 30 and is used for temporarily storing and transferring liquid. For example, either the liquid reservoir 8 or the liquid guide 30 may be made of cotton material.

[0046] Please see Figure 11 and Figure 12 In some embodiments, the liquid inlet channel 16 includes a first channel 161 and a second channel 162 that are bent and connected. The first channel 161 is connected to the first liquid storage chamber 5, and the second channel 162 is connected to the mounting hole 14. The liquid storage component 8 is at least partially fitted and fixed with the second channel 162. The extending direction of the first channel 161 and the extending direction of the second channel 162 can form a 90-degree angle, such as... Figure 11 and Figure 12 As shown by the dashed line in the image. Figure 11 and Figure 12 The dashed line with an arrow indicates the bend in the path connecting the first channel 161 and the second channel 162, which is also the path of liquid flow. Alternatively, in some embodiments, the extending directions of the first channel 161 and the second channel 162 may form other angles. Please refer to [further details needed]. Figure 7 The liquid reservoir 8 is at least partially fitted and fixed within the second channel 162, thereby fixing at least a portion of the liquid reservoir 8 within the second channel 162. This prevents the liquid reservoir 8 from easily shifting, provides good positional stability, and creates a good liquid-conducting function. Specifically, as... Figure 7 In the illustrated embodiment, a portion of the liquid storage component 8 is embedded within the second channel 162 for fixation, while another portion is exposed to the first channel 161, allowing the first channel 161 to serve as a liquid inlet space. Alternatively, in other embodiments, the liquid storage component 8 may be entirely embedded within the second channel 162.

[0047] Please see Figure 9 and Figure 10 In some embodiments, the housing 6 includes a housing body 61 and a first support portion 62 connected to the housing body 61. The housing body 61 is fitted onto the first atomizing seat 1, and the first atomizing seat 1 and the housing body 61 are sealed together, defining a first liquid storage cavity 5. A first sealing rib 13 on the outer periphery of the first atomizing seat 1 contacts the inner wall surface of the housing body 61, achieving a seal between the first atomizing seat 1 and the housing body 61. The top surface 17 of the first atomizing seat 1 faces the first liquid storage cavity 5. The first support portion 62 extends into the liquid inlet channel 16 and abuts against the first atomizing seat 1. Specifically, the first support portion 62 abuts against the bottom surface of the liquid inlet channel 16. Thus, the first support portion 62 provides support force to the first atomizing seat 1 in the XX direction. Specifically, as Figures 7 to 9As shown, the liquid storage component 8 is provided with a clearance groove 81. The shape and size of the clearance groove 81 are adapted to the shape and size of the portion of the first support part 62 that extends into the liquid inlet channel 16, and are used to provide clearance for the first support part 62, so that the first support part 62 extends into the clearance groove 81 and abuts against the first atomizing seat 1. The first support part 62 can be a T-shaped plate as shown in the figure, or it can be in other states.

[0048] Please see Figures 9 to 11 In some embodiments, the first side surface 11 is provided with a notch 18. Specifically, the notch 18 extends through both the first outer side surface 111 and the first inner side surface 112. The notch 18 and the liquid inlet channel 16 are located on opposite radial sides of the first atomizing seat 1. The notch 18 and the mounting hole 14 are in fluid communication. The second atomizing seat 2 includes a second support portion 23, which extends along the XX direction. Specifically, the second support portion 23 protrudes along the XX direction relative to other locations on the first atomizing seat 1. The second support portion 23 extends into the notch 18 and abuts against the first atomizing seat 1. Thus, the second support portion 23 provides support force to the first atomizing seat 1 along the XX direction.

[0049] In summary, the first support portion 62 and the second support portion 23 provide support forces along the XX direction to the first atomizing seat 1 on opposite sides of the first atomizing seat 1, so that the first atomizing seat 1 can be effectively and stably supported, ensuring the effective sealing of the assembly boundary between the atomizing core 3 and the mounting hole 14; the displacement of the first atomizing seat 1 along the XX direction is restricted, which also prevents the first atomizing seat 1 from sliding relative to the housing 6 along the XX direction, ensuring the effective sealing of the first liquid storage chamber 5.

[0050] like Figures 7 to 12 As shown, in some embodiments, the first atomizing base 1 is further provided with an air outlet 15. The air outlet 15 penetrates the top surface 17. When the atomizing core 3 is not installed in the mounting hole 14, the air outlet 15 and the liquid inlet channel 16 are in fluid communication with the mounting hole 14, respectively. When the atomizing core 3 is installed in the mounting hole 14, the air outlet 15 and the liquid inlet channel 16 are in fluid communication with the atomizing core 3, respectively. The air outlet 15 is used to output aerosol, and the aerosol generated at the atomizing core 3 is output outward through the air outlet 15. The airflow direction through the air outlet 15 is parallel to the atomizing surface. The generated aerosol is transported from the air outlet 15 to the outside of the atomizer for the user to inhale. Further, in some embodiments, the notch 18 is also connected to the air outlet 15. The notch 18 can serve as an atomizing chamber, where the aerosol generated at the atomizing core 3 can accumulate. This allows the aerosol and air to mix evenly and then flow out through the air outlet 15, thus reducing the temperature of the aerosol.

[0051] Please see Figures 9 to 11In some embodiments, the housing 6 includes a housing body 61 and an air guiding channel 63 formed on the housing body 61. The housing body 61 is fitted onto the first atomizing seat 1, and the first atomizing seat 1 and the housing body 61 together define a first liquid storage chamber 5. The air guiding channel 63 and the air outlet 15 are in fluid communication. Figures 7 to 10 As shown, the shell body 61 is generally cylindrical and is fitted around the first atomizing seat 1 and the second atomizing seat 2. The shell body 61 and the second atomizing seat 2 are fastened together. The shell body 61 includes an outer shell portion 611 and a tube portion 612. The cross-sectional dimension of the outer shell portion 611 is larger than that of the tube portion 612, wherein the transverse direction of the cross-section can be referenced to a direction perpendicular to the XX direction. A first support portion 62 is connected to the inner wall surface of the outer shell portion 611. The outer shell portion 611 is fitted around the first atomizing seat 1 and the second atomizing seat 2, and the first atomizing seat 1 and the outer shell portion 611 are sealed together. A first sealing rib 13 on the outer periphery of the first atomizing seat 1 contacts the inner wall surface of the outer shell portion 611, achieving a seal between the first atomizing seat 1 and the outer shell portion 611. The air guiding channel 63 is formed in the tube 612 and extends along the length direction of the tube 612, which is aligned with the XX direction. One end of the tube 612 along its length direction is embedded in the air outlet 15. The tube 612 and the air outlet 15 can be an interference fit. A raised second sealing rib can be provided on the inner wall of the air outlet 15. The second sealing rib contacts the tube 612 to achieve a seal between the tube 612 and the air outlet 15. The first sealing rib 13 contacts the inner wall surface of the outer shell 611. The interference fit between the tube 612 and the air outlet 15 can be 0.15 to 0.2 mm, and the sealing performance must reach 101 kPa in the air pressure test. The outer shell 611 and the first atomizing seat 1 are spaced apart along the XX direction. Thus, the outer peripheral surfaces of the outer shell 611, the tube 612, and the first atomizing seat 1 together define a closed first liquid storage chamber 5.

[0052] Please see Figures 8 to 11 In some embodiments, at least two first engaging portions 12 are located on opposite sides of the notch 18; specifically, at least two first engaging portions 12 are located on opposite sides of the notch 18 along the circumference of the first atomizing seat 1. At least two second engaging portions 22 are located on the second support portion 23. The two sides of the second support portion 23 along its thickness direction constitute at least a portion of the second side surface 21.

[0053] Please see Figures 8 to 11 In some embodiments, at least one first engaging portion 12 is a protrusion or through hole formed on the first side surface 11. At least one second engaging portion 22 is a protrusion or through hole formed on the second side surface 21, and the protrusion and the through hole are fitted together. Specifically, the first engaging portion 12 as a protrusion and the second engaging portion 22 as a through hole are fitted together; the first engaging portion 12 as a through hole and the second engaging portion 22 as a protrusion are fitted together.

[0054] like Figures 8 to 11 In the illustrated embodiment, there are four first fastening portions 12, each of which is a protrusion formed on the first inner side surface 112. The second side surface 21 includes opposing second outer side surface 211 and second inner side surface 212. The second outer side surface 211 and the second inner side surface 212 are located on opposite sides of the second support portion 23 along its thickness direction. There are four second fastening portions 22, each of which is a through hole penetrating the second outer side surface 211 and the second inner side surface 212. Of course, in some other embodiments, the first fastening portion 12, as a protrusion, may also be formed on the first outer side surface 111. The second fastening portion 22, as a protrusion, may be formed on the second outer side surface 211 or the second inner side surface 212. The number and shape of the first fastening portions 12 and the second fastening portions 22 can be flexibly adjusted.

[0055] Please see Figures 2 to 5 , Figure 13 In some embodiments, the present invention also provides a liquid storage unit 7, which includes a second liquid storage chamber 71, at least one first liquid guiding hole 72, and at least one liquid blocking element 74. The second liquid storage chamber 71 is used to store the atomizing matrix. Each first liquid guiding hole 72 connects the interior and exterior of the second liquid storage chamber 71. Each liquid blocking element 74 is disposed in one of the first liquid guiding holes 72 and is used to seal the first liquid guiding hole 72. That is, the liquid blocking element 74 and the first liquid guiding hole 72 are in a one-to-one correspondence, and each first liquid guiding hole 72 is sealed with one liquid blocking element 74. Furthermore, the liquid blocking element 74 is movably engaged with its corresponding first liquid guiding hole 72. When the liquid blocking element 74 is removed from the first liquid guiding hole 72 or pushed into the second liquid storage chamber 71, the first liquid guiding hole 72 is exposed, allowing the atomizer to be replenished with the atomizing matrix; when the liquid blocking element 74 is inserted into the first liquid guiding hole 72 and seals with it, it seals the second liquid storage chamber 71.

[0056] Please see Figures 2 to 5 , Figure 13In some embodiments, the present invention also provides an atomizer assembly according to a first embodiment, which includes an atomizer according to any of the above embodiments and a liquid storage unit 7 used in conjunction with the atomizer. The liquid storage unit 7 and the atomizer are detachably connected. The liquid storage unit 7 has a second liquid storage chamber 71. The second liquid storage chamber 71 is also used to store liquid atomizing matrix. When the atomizer and the liquid storage unit 7 are installed together, the second liquid storage chamber 71 is connected to the first liquid storage chamber 5, supplying the atomizing matrix to the first liquid storage chamber 5. The atomizing matrix is ​​temporarily stored in the first liquid storage chamber 5, and the atomizing matrix in the first liquid storage chamber 5 flows directly to the atomizing core 3 and is consumed. The liquid storage unit 7 and the housing 6 are detachably connected. The liquid storage unit 7 can be transported separately. Furthermore, the user can remove the liquid storage unit 7 at any time to replenish the atomizing matrix in the second liquid storage chamber 71.

[0057] like Figure 6 and Figure 13 As shown, in some embodiments, the housing 6 is provided with at least one liquid guiding column 64. The number of liquid guiding columns 64 is the same as the number of first liquid guiding holes 72. Each liquid guiding column 64 has a hollow interior forming a second liquid guiding hole 60. When the atomizer and the liquid storage unit 7 are installed together, the liquid guiding column 64 pushes the liquid blocking member 74 into the third liquid storage chamber 70, and the liquid guiding column 64 extends into the first liquid guiding hole 72, so that the first liquid guiding hole 72 and the second liquid guiding hole 60 are connected, thereby realizing the fluid communication between the third liquid storage chamber 70 and the second liquid storage chamber 5. In some embodiments, when the atomizing matrix in the second liquid storage chamber 71 is almost exhausted, the user can remove the liquid storage unit 7 from the housing 6 and replenish the atomizing matrix into the second liquid storage chamber 71 through the first liquid guiding hole 72.

[0058] like Figure 13 As shown, this utility model also provides another atomizer assembly according to a second embodiment, which is similar to the atomizer assembly of the first embodiment described above in that the atomizer assembly of the second embodiment includes an atomizer and a liquid storage unit 7, which are used in conjunction with the atomizer. The liquid storage unit 7 includes a second liquid storage chamber 71, at least one first liquid guiding hole 72, and at least one liquid blocking member 74. The second liquid storage chamber 71 is used to store the atomizing matrix. The at least one first liquid guiding hole 72 communicates the interior and exterior of the second liquid storage chamber 71. The at least one liquid blocking member 74 is disposed in the first liquid guiding hole 72 for sealing the first liquid guiding hole 72.

[0059] This atomizer assembly differs from the aforementioned atomizer assembly in that it does not include a first atomizing seat 1 and a second atomizing seat 2. The atomizer includes a housing 6, a first liquid storage chamber 5, and an atomizing core 3. The housing 6 has at least one liquid guiding column 64, each liquid guiding column 64 forming a second liquid guiding hole 60. The first liquid storage chamber 5 is in fluid communication with the second liquid guiding hole 60 and is used to store the atomizing matrix. The atomizing core 3 is disposed within the space enclosed by the housing 6 and is used to heat and atomize the atomizing matrix to generate an aerosol. The liquid guiding column 64 is used to push the liquid blocking member 74 into the interior of the second liquid storage chamber 71, thereby enabling fluid communication between the second liquid guiding hole 60 and the first liquid guiding hole 72.

[0060] like Figure 4 , Figure 7 and Figure 13 As shown, in some embodiments, the liquid storage unit 7 further includes a second air outlet channel 73, which is isolated from the second liquid storage chamber 71. When the liquid storage unit 7 is installed on the housing 6, the second air outlet channel 73, the air guide channel 63, and the air outlet 15 are in sequential fluid communication. The mixture of aerosol and air generated at the atomizing core 3 flows out sequentially from the air outlet 15, the air guide channel 63, and the second air outlet channel 73 for the user to inhale.

[0061] This utility model also provides an electronic atomizing device according to another embodiment, which includes a battery assembly 4 and an atomizer assembly of any of the above embodiments, wherein the battery assembly 4 and the atomizer assembly are connected to the atomizer.

[0062] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
