Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to an atomizer and atomization device. Background Technology

[0002] As part of an atomizing device, an atomizer typically has a receiving chamber inside. The receiving chamber is used to contain the aerosol forming matrix, and the atomizer is used to heat the aerosol forming matrix inside the receiving chamber.

[0003] Atomizers employ various heating methods, including center heating and circumferential heating. Center heating, specifically, can utilize electromagnetic center heating to heat the aerosol-forming matrix inserted into the atomizer. When an atomizer uses electromagnetic center heating, a heating element is typically located within the housing cavity to insert the aerosol-forming matrix. This presence of a heating element within the housing cavity presents two challenges: firstly, it makes inserting the aerosol-forming matrix into the housing cavity inconvenient; secondly, it increases the difficulty of cleaning the housing cavity. Utility Model Content

[0004] This application provides an atomizer and an atomizing device, the main purpose of which is to reduce the difficulty of cleaning the containment cavity and the difficulty of inserting aerosols into the containment cavity to form a matrix.

[0005] According to a first aspect of this application, an atomizer is provided, comprising:

[0006] An atomizing cup, wherein the atomizing cup is a non-magnetic component, a receiving cavity is formed within the atomizing cup for containing an aerosol forming matrix, and a magnetic component is pre-installed within the aerosol forming matrix; and

[0007] An electromagnetic coil is disposed on the outside of the atomizing cup. The electromagnetic coil is used in conjunction with the magnetic component to heat the aerosol matrix by electromagnetic induction heating.

[0008] In one embodiment, the atomizing cup is provided with an air intake channel communicating with the outside, and the air intake channel is used to separate the inner wall of the atomizing cup from the outer wall of the aerosol forming matrix.

[0009] In one embodiment, the inner sidewall of the atomizing cup is provided with a plurality of first support portions, and an axial air passage is formed between adjacent first support portions. The inner bottom wall of the atomizing cup is provided with a plurality of second support portions, and a radial air passage is formed between adjacent second support portions. The axial air passage and the radial air passage are connected to form the air intake passage.

[0010] In one embodiment, the first support portion is strip-shaped, and a groove-shaped axial air passage is formed between adjacent first support portions; an arc-shaped surface is provided at one end of the first support portion away from the inner wall of the atomizing cup, and the arc-shaped surface is used to contact the outer wall surface of the aerosol forming matrix.

[0011] In one embodiment, the thickness of the first support portion along the radial direction of the atomizing cup is 0.1-1 mm.

[0012] In one embodiment, the electromagnetic coil is sleeved and fixed to the outer wall of the atomizing cup.

[0013] In one embodiment, a limiting part is provided on the outer wall of the atomizing cup, and the limiting part abuts against any end of the electromagnetic coil.

[0014] In one embodiment, the atomizing cup has a guide cavity at its opening that is adjacent to the receiving cavity, and the guide cavity is used to assist the aerosol forming matrix in being inserted into the receiving cavity.

[0015] According to a second aspect of this application, an atomizing device is provided, comprising an aerosol forming matrix and the aforementioned atomizer.

[0016] In one embodiment, the aerosol forming matrix has a liquid-absorbing layer at one end near the bottom of the atomizing cup.

[0017] According to the atomizer in the above embodiments, the atomizer includes an atomizing cup containing an aerosol-forming matrix and an electromagnetic coil disposed outside the atomizing cup.

[0024] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0025] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0026] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0027] One embodiment of this application provides an atomizer, which is part of an atomizing device and is mainly used to heat the aerosol forming matrix 30 to a degree sufficient to emit mist in a heating-non-combustible manner. The mist emitted by the heated aerosol forming matrix 30 is used for inhalation by a user.

[0028] Please see Figures 1-5 The atomizer includes an atomizing cup 10 and an electromagnetic coil 20. The atomizing cup 10 is a non-magnetic component 40, for example, the atomizing cup 10 is made of a high-temperature resistant non-magnetic material. A receiving cavity 10c is formed inside the atomizing cup 10 to receive an aerosol forming matrix 30, and a magnetic component 40 is pre-installed inside the aerosol forming matrix 30. The electromagnetic coil 20 is disposed on the outside of the atomizing cup 10, and the electromagnetic coil 20 is used to cooperate with the magnetic component 40 to heat the aerosol forming matrix 30 by electromagnetic induction heating.

[0029] The atomizer described in the above embodiment includes an atomizing cup 10 that houses the aerosol forming matrix 30 and an electromagnetic coil 20 disposed outside the atomizing cup 10. The aerosol forming matrix 30 housed in the atomizing cup 10 contains a magnetic element 40. Thus, the electromagnetic coil 20 can cooperate with the magnetic element 40 in the aerosol forming matrix 30 to heat the aerosol forming matrix 30 via electromagnetic induction heating. The atomizing cup 10 housing the aerosol forming matrix 30 is a relatively complete structure, and there is no need to install a heating element for inserting the aerosol forming matrix 30 inside the atomizing cup 10. That is, the receiving cavity 10c inside the atomizing cup 10 is a relatively empty chamber. There is no obstruction when the aerosol forming matrix 30 is inserted into the receiving cavity 10c inside the atomizing cup 10, facilitating rapid insertion of the aerosol forming matrix 30 into the receiving cavity 10c and also facilitating cleaning of the entire receiving cavity 10c. The atomizing cup 10 is made of non-magnetic material, which effectively ensures the cooperation effect between the electromagnetic coil 20 and the magnetic component 40 in the aerosol forming matrix 30, and avoids interference between the electromagnetic coil 20 and the magnetic component 40 due to the magnetic content of the atomizing cup 10.

[0030] The magnetic component 40 embedded in the aerosol forming matrix 30 inserted into the atomizer is a magnetic material with a certain magnetic permeability, such as a ferromagnetic pure metal or alloy conductor, or an inorganic non-metallic conductor such as ceramic or carbon fiber that has undergone ferromagnetization treatment. The electromagnetic coil 20 is electrically connected to the electronic control component, which can provide alternating current to the electromagnetic coil 20. When the current is applied, the electromagnetic coil 20 generates an alternating magnetic field. The magnetic component 40 embedded in the aerosol forming matrix 30 is subjected to the alternating magnetic field, generating eddy currents and heating up, which in turn directly heats the aerosol forming matrix 30.

[0031] For a better option, please refer to Figures 1-5The atomizing cup 10 has an air intake channel that communicates with the outside. The air intake channel is used to separate the inner wall of the atomizing cup 10 from the outer wall of the aerosol forming matrix 30.

[0032] It should be noted that the inner wall of the atomizing cup 10 includes the inner side wall and the inner bottom wall of the atomizing cup 10, and the outer wall of the aerosol forming matrix 30 includes the outer side wall and the outer bottom wall of the aerosol forming matrix 30. It can be understood that the outer bottom wall refers to the end face of the aerosol forming matrix 30 near the bottom 10a of the atomizing cup 10.

[0033] By providing an air intake channel that communicates with the outside world inside the atomizing cup 10, when the user uses the atomizer to inhale the aerosol forming matrix 30, outside air can flow through the cup opening 10b of the atomizing cup 10, sequentially through the side wall space between the inner side wall of the atomizing cup 10 and the outer side wall of the aerosol forming matrix 30, and the bottom wall space between the inner bottom wall of the atomizing cup 10 and the outer bottom wall of the aerosol forming matrix 30. Finally, the air flows into the aerosol forming matrix 30 through the bottom end face of the aerosol forming matrix 30.

[0034] Since the magnetic component 40 and the electromagnetic coil 20 in the aerosol forming matrix 30 can generate heat when combined, the heat generated by the magnetic component 40 can not only directly heat the aerosol forming matrix 30, but also diffuse radially to the side wall space between the side wall of the atomizing cup 10 and the side wall of the aerosol forming matrix 30, and even diffuse to the bottom wall space between the bottom wall of the atomizing cup 10 and the bottom wall of the aerosol forming matrix 30. This allows the outside air to be heated and turned into hot air flow when it flows through the air inlet channel. After the hot air flow flows into the aerosol forming matrix 30, it can also heat the aerosol forming matrix 30.

[0035] During the heating process of aerosol forming matrix 30, outside air is also drawn into aerosol forming matrix 30. The outside air is relatively cold. If the cold air flows directly into aerosol forming matrix 30, a temperature difference will be formed between it and the heated part of aerosol forming matrix 30, which will affect the heating effect and heating speed of aerosol forming matrix 30.

[0036] Correspondingly, this application provides an air intake channel within the atomizing cup 10. Outside air passes through this channel, and the magnetic component 40 diffuses heat to the air intake channel, heating the outside air into a hot airflow. This hot airflow flows into the aerosol forming matrix 30, further heating the aerosol forming matrix 30 and thus increasing the heating rate and improving the heating effect. As a relatively closed container, the atomizing cup 10, with its air intake channel, reduces heat loss, allowing heat to accumulate within the atomizing cup 10 for full utilization and improved heat efficiency.

[0037] For details, please refer to Figure 3 The inner sidewall of the atomizing cup 10 is provided with multiple first support portions 11, which are used to contact the outer sidewall of the aerosol forming matrix 30. An axial airway 11a (i.e., the sidewall space mentioned above) is formed between adjacent first support portions 11. The inner bottom wall of the atomizing cup 10 is provided with multiple second support portions 12, which are used to contact the outer bottom wall of the aerosol forming matrix 30. A radial airway 12a (i.e., the bottom wall space mentioned above) is formed between adjacent second support portions 12. The axial airway 11a and the radial airway 12a are connected to form an air intake airway.

[0038] More specifically, the first support portion 11 is strip-shaped, and a groove-shaped axial air passage 11a is formed between adjacent first support portions 11. One end of the first support portion 11 away from the inner wall of the atomizing cup 10 has an arc-shaped surface, which is used to contact the outer wall surface of the aerosol forming matrix 30. The arc-shaped surface on the first support portion 11 ensures a certain contact area between the atomizing cup 10 and the aerosol forming matrix 30, facilitating the clamping and fixing of the aerosol forming matrix 30, or ensuring the stability of the aerosol forming matrix 30 within the atomizing cup 10.

[0039] For example, Figure 3 As shown, the inner wall of the atomizing cup 10 is provided with multiple equally spaced strip-shaped first support portions 11. The length direction of the first support portions 11 can be set to be parallel to the axial direction of the atomizing cup 10. A curved surface can be used to transition between the same first support portion 11 and the axial air passages 11a on both sides of the circumference, thus forming a petal-like structure with the multiple first support portions 11 and multiple axial air passages 11a on the inner wall of the atomizing cup 10. For example... Figure 4 As shown, the inner wall of the atomizing cup 10 is provided with four circumferentially equally spaced first support portions 11, and four axial air channels 11a are formed between the four first support portions 11. The four first support portions 11 and the four axial air channels 11a form a plum blossom-shaped receiving cavity 10c. The plum blossom-shaped receiving cavity 10c can clamp and fix the aerosol forming matrix 30 through the arc-shaped surface provided on the first support portions 11. The axial channels formed can ensure a certain air intake (i.e., the amount of outside air flowing into the atomizing cup 10). Furthermore, the plum blossom-shaped receiving cavity 10c can fix the aerosol forming matrix 30 in the center inside the atomizing cup 10, which is convenient for uniform heating of the aerosol forming matrix 30 as a whole.

[0040] Please see Figure 4In the diagram, the large dashed circle corresponds to the inner wall of the atomizing cup 10, and the small dashed circle corresponds to the radial end face of the first support portion 11 on the inner wall of the atomizing cup 10. The thickness D of the first support portion 11 along the radial direction of the atomizing cup 10 is 0.1-1mm, that is, the thickness D of the first support portion 11 protruding inward along the radial direction of the atomizing cup 10 is 0.1-1mm. For example, the thickness D of the first support portion 11 along the radial direction of the atomizing cup 10 is 0.5mm. By designing the thickness range of the first support portion 11 along the radial direction of the atomizing cup 10, the air intake space of the axial air passage 11a can be guaranteed, thereby ensuring the air intake volume within the atomizing cup 10.

[0041] Please see Figures 3-4 The second support 12 is, for example, a protrusion structure, and multiple second support 12 are fixed at intervals to the bottom 10a of the atomizing cup 10.

[0042] In other embodiments, the first support portion 11 and the second support portion 12 can be other forms of structures besides those listed, such as the first support portion 11 being a block structure and the second support portion 12 being a strip structure. The number of the first support portion 11 and the second support portion 12 can be multiple, or each can be one. This application does not impose specific limitations on the structure and number of the first support portion 11 and the second support portion 12, as long as the functions of the first support portion 11 and the second support portion 12 can be achieved.

[0043] Please see Figures 1-2 In some embodiments of this application, the electromagnetic coil 20 is sleeved and fixed to the outer wall of the atomizing cup 10. The aerosol forming matrix 30 is typically cylindrical, and the corresponding atomizing cup 10 and the sleeved electromagnetic coil 20 are also cylindrical. An electromagnetic element, such as a needle-shaped, rod-shaped, or columnar electromagnetic element, is provided at the center of the aerosol forming matrix 30. The electromagnetic coil 20, sleeved on the outside of the atomizing cup 10, can generate a centrally located magnetic field, so that the electromagnetic element at the center of the aerosol forming matrix 30 can be sufficiently heated.

[0044] Please see Figure 1 The aerosol forming matrix 30 used in conjunction with the atomizer includes a matrix section 31, a cooling section 32, and a filter section 33 connected axially in sequence. The matrix section 31 and at least a portion of the cooling section 32 are inserted into the atomizing cup 10. A magnetic element 40 is pre-installed within the matrix section 31. To clearly show the columnar magnetic element 40, the magnetic element 40 is... Figure 1 The magnetic component 40 is shown in bold black. The length of the magnetic component 40 along the axial direction of the atomizing cup 10 can be greater than or equal to the length of the electromagnetic coil 20 along the axial direction of the atomizing cup 10.

[0045] In other embodiments, the aerosol forming matrix 30 can also be of other shapes, and correspondingly, the shapes of the atomizing cup 10 and the electromagnetic coil 20 can also be other suitable shapes, as long as the magnetic field generated by the electromagnetic coil 20 is centrally distributed within the atomizing cup 10.

[0046] In other embodiments, in addition to being sleeved on the outside of the atomizing cup 10, the electromagnetic coil 20 can also be fixed to the bottom 10a of the atomizing cup 10. In this case, the electromagnetic coil is, for example, a spiral disc structure.

[0047] Please see Figures 1-3 In some embodiments of this application, a limiting part 13 is provided on the outer wall of the atomizing cup 10, and the limiting part 13 abuts against any end of the electromagnetic coil 20. For example, the limiting part 13 is provided on the side of the outer wall of the atomizing cup 10 near the cup opening 10b of the atomizing cup 10, and the top of the electromagnetic coil 20 abuts against the limiting part 13.

[0048] The limiting part 13 can be a block-shaped or ring-shaped structure. For example, the outer wall of the atomizing cup 10 is provided with four equally spaced block-shaped limiting parts 13. This application does not limit the specific form of the limiting part 13, as long as the limiting part 13 can perform the function of limiting the electromagnetic coil 20.

[0049] The atomizer also includes a sleeve (not shown), within which an atomizing cup 10 is fitted. An assembly portion 14 is provided on the outer wall of the atomizing cup 10, located on the side of the limiting portion 13 near the cup opening 10b of the atomizing cup 10. The atomizing cup 10 is fitted into the sleeve via the assembly portion 14, and the assembly portion 14 radially and upwardly separates the atomizing cup 10 and the sleeve. The assembly portion 14 is, for example, as shown... Figure 2 As shown, it is a ring-shaped plate.

[0050] Please see Figure 1 The atomizing cup 10 has a guide cavity 10d at the cup mouth 10b adjacent to the receiving cavity 10c. The guide cavity 10d is a chamber formed by an annular conical surface. From the side away from the receiving cavity 10c to the side closer to the receiving cavity 10c, the radial dimension of the guide cavity 10d continuously decreases. The guide cavity 10d is used to assist the aerosol forming matrix 30 in being inserted into the receiving cavity 10c.

[0051] Preferably, the atomizing cup 10 also includes a transition cavity 10e, with its two ends adjacent to the cup opening 10b and the guide cavity 10d of the atomizing cup 10, respectively. The transition cavity 10e is an annular cylindrical chamber, and the transition cavity 10e, the guide cavity 10d, and the receiving cavity 10c are interconnected and coaxially distributed. The transition cavity 10e and the guide cavity 10d cooperate to facilitate the rapid insertion of the aerosol forming matrix 30 into the receiving cavity 10c.

[0052] The atomizer in the above embodiments of this application has a first support portion 11 on the inner wall of the atomizing cup 10, which can clamp and fix the aerosol forming matrix 30 in the receiving cavity 10c. A second support portion 12 is provided on the inner bottom wall of the atomizing cup 10. The first support portion 11 forms an axial airway 11a in the atomizing cup 10, and the second support portion 12 forms a radial airway 12a in the atomizing cup 10. The axial airway 11a and the radial airway 12a are connected to form an air intake channel in the atomizing cup 10. External air can flow to the bottom 10a of the atomizing cup 10 through the air intake channel and flow into the aerosol forming matrix 30 through the outer bottom wall of the aerosol forming matrix 30. After the magnetic component 40 and the electromagnetic coil 20 cooperate to generate heat, they can not only directly heat the contacting aerosol forming matrix 30, but also diffuse the generated heat to the axial airway 11a and the radial airway 12a, heating the airflow there to obtain a hot airflow, which can further heat the aerosol forming matrix 30. The designed atomizer uses electromagnetic central heating combined with hot airflow heating on the inner wall of the atomizing cup 10, which can fully and quickly heat the aerosol forming matrix 30, improve thermal energy utilization, and reduce heat loss.

[0053] Another embodiment of this application provides an atomizing device, including an aerosol forming matrix 30, an electronic control component, a housing, and the atomizer described in the above embodiment. Neither the electronic control component nor the housing is shown in the figure. Both the electronic control component and the atomizer are fixed within the housing. The electronic control component and the electromagnetic coil 20 in the atomizer are electrically connected. The electronic control component is used to control the electromagnetic coil 20, for example, to control the on / off switching of the alternating current in the electromagnetic coil 20.

[0054] The aerosol forming matrix 30 has a pre-installed magnetic component 40 that works in conjunction with the electromagnetic coil 20. The heating element in the atomizing device is provided by the magnetic component 40 pre-installed in the aerosol forming matrix 30, eliminating the need for a dedicated heating element in the atomizing cup 10. This simplifies the structure of the atomizing cup 10, allows for unobstructed insertion of the aerosol forming matrix 30, and facilitates quick and easy connection. When cleaning the space inside the atomizing cup 10, the absence of a heating element makes cleaning easier and more efficient. Furthermore, since the magnetic component 40, which acts as the heating element, is entirely pre-installed within the aerosol forming matrix 30, almost all the heat generated by the magnetic component 40 through the eddy current effect can be used to heat the aerosol forming matrix 30, improving thermal energy utilization and reducing heat loss.

[0055] For a better option, please refer to Figure 1The aerosol forming matrix 30 has a liquid-absorbing layer 34 at one end near the bottom 10a (i.e., the outer bottom wall) of the atomizing cup 10. The liquid-absorbing layer 34 is, for example, absorbent cotton. When the aerosol forming matrix 30 is heated, the mist generated will produce condensate when it cools. If the mist or condensate flows to the bottom of the aerosol forming matrix 30, it can be absorbed in time by the liquid-absorbing layer 34, avoiding the accumulation of condensate on the inner wall of the atomizing cup 10. This ensures the cleanliness of the atomizing cup 10 and reduces the frequency of cleaning the atomizing cup 10.

[0056] If the magnetic component 40 is not pre-installed within the aerosol forming matrix 30, but is instead located on the inner bottom wall of the atomizing cup 10, the liquid absorption layer 34 will be additionally heated after the magnetic component 40 heats up. Furthermore, the heat generated by the magnetic component 40, which is located between the inner bottom wall of the atomizing cup 10 and the outer bottom wall of the aerosol forming matrix 30, cannot be effectively utilized.

[0057] The atomizer or atomizing device containing an atomizer designed in this application has the magnetic component 40 pre-embedded within the aerosol forming matrix 30, and the liquid absorption layer 34 is spaced apart from the magnetic component 40. This avoids the phenomenon of ineffective heating caused by the magnetic component 40 heating and baking the liquid absorption layer 34. The heat generated by the magnetic component 40 is used as much as possible to heat the aerosol forming matrix 30, thereby improving the heating effect on the aerosol forming matrix 30.

[0058] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
