Similar elements in different embodiments are given similar reference numerals. In the following embodiments, many details are described in order to make the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different cases, or replaced by other elements, materials or methods.

[0030] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments. At the same time, the steps or actions in the method description can also be sequentially adjusted or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.
[0031] The serial numbers of the components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and have no order or technical meaning. Unless otherwise specified, the "connection" and "coupling" in this application include direct and indirect connections (couplings).
[0032] Please refer to Figure 1 and Figure 2 The present application provides an atomizer, which comprises a housing 1, an atomization assembly 2, a buffer 3 and an atomization seat 4. The housing 1 defines a liquid storage cavity 10 for storing an atomization substrate. The atomization substrate can be a liquid atomization substrate. The atomization assembly 2 is arranged in the housing 1 and is used for heating the atomization substrate to generate an aerosol. The housing 1 encloses a cavity, and the atomization assembly 2, the buffer 3 and the atomization seat 4 can all be arranged in the cavity. The buffer 3 is arranged around the atomization assembly 2 and is used for buffering the atomization substrate. The atomization seat 4 is arranged on one side of the liquid storage cavity 10 and is used for sealing the liquid storage cavity 10. Specifically, as shown in Figure 2 , in the upright state of the atomizer, the atomization seat 4 is located below the liquid storage cavity 10.
[0033] The buffer member 3 is arranged on the path of the atomized substrate flowing from the liquid storage cavity 10 to the atomization assembly 2. For example, the buffer member 3 can be arranged between the liquid storage cavity 10 and the atomization assembly 2. The buffer member 3 can be made of a fiber material, which can include one or more of natural cotton, bamboo fiber, glass fiber, PA (polyamide, commonly known as nylon), PET (polyethylene terephthalate, commonly known as polyester), CA (cellulose acetate) of textiles. The buffer member 3 has a certain liquid storage capacity, can guide the liquid atomized substrate from the liquid storage cavity 10, and slowly guide the liquid atomized substrate to the atomization assembly 2. The atomization assembly 2 generates heat in the energized state, and the atomized substrate guided from the buffer member 3 to the atomization assembly 2 is heated and atomized after contacting the atomization assembly 2 in the heating state, thereby generating aerosol for the user to inhale. Because the buffer member 3 is arranged on the path of the atomized substrate flowing from the liquid storage cavity 10 to the atomization assembly 2, the buffer member 3 can serve as a liquid guiding transition element between the liquid storage cavity 10 and the atomization assembly 2, can slow down the liquid absorption rate of the atomization assembly 2, increase the time required for the atomization assembly 2 to absorb liquid, and reduce the risk of leakage of the atomized substrate.
[0034] Because the liquid absorption rate of the atomization assembly 2 is slowed down, when negative pressure is generated in the liquid storage cavity 10 due to temperature change or suction, in order to reduce the obstruction of the atomization assembly 2 to guide liquid, the atomization seat 4 is provided with an air exchange structure 41 for communicating the liquid storage cavity 10 with the atmosphere. When the pressure in the liquid storage cavity 10 changes, for example, negative pressure is generated in the liquid storage cavity 10 due to temperature change or suction, because the liquid storage cavity 10 and the atmosphere are communicated through the air exchange structure 41, the negative pressure in the liquid storage cavity 10 can be balanced, thereby reducing the risk of obstruction of the atomization assembly 2 to guide liquid. On the other hand, under the influence of temperature change, when the air pressure in the liquid storage cavity 10 is greater than the external atmospheric pressure, the atomized substrate in the liquid storage cavity 10 will be squeezed, and in the state that the atomizer is not working (for example, the state of transportation, shelf storage or user storage), the generation of the squeezing force will increase the risk of liquid leakage at the atomization assembly 2. Because the liquid storage cavity 10 and the atmosphere are communicated through the air exchange structure 41, the positive pressure generated in the liquid storage cavity 10 can also be balanced, thereby reducing the risk of liquid leakage. By connecting the liquid storage cavity 10 and the atmosphere through the air exchange structure 41 on the atomization seat 4, the pressure change generated in the liquid storage cavity 10 can be balanced, thereby reducing the risk of obstruction of the atomization assembly 2 to guide liquid and liquid leakage.
[0035] Please refer to Figures 3 to 5 In some embodiments, the atomization seat 4 is provided with a receiving groove 42. As shown in Figure 5As shown, the receiving slot 42 includes a first receiving area 421 and a second receiving area 422. The second receiving area 422 is disposed around the first receiving area 421. The atomizing component 2 is at least partially received in the first receiving area 421. The atomizing component 2 may be partially or completely received in the first receiving area 421. The buffer 3 is at least partially received in the second receiving area 422. The buffer 3 may be partially or completely received in the second receiving area 422. Therefore, the buffer 3 is at least partially disposed around the atomizing component 2, that is, the buffer 3 at least partially surrounds the atomizing component 2. Since the second receiving area 422 is disposed around the first receiving area 421, the maximum lateral width of the second receiving area 422 is greater than the maximum lateral width of the first receiving area 421. "lateral" can be referred to as... Figure 5 The CC direction in [the equation / reference]. For example... Figure 5 As shown, the inner wall of the receiving groove 42 has two parts with different transverse dimensions to form a stepped structure on the inner wall of the receiving groove 42. Combined with... Figure 2 and Figure 5 As shown, the buffer 3 can rest against the stepped structure. Therefore, the atomizing base 4 can also be used to install the buffer 3 and the atomizing assembly 2.
[0036] Please see Figure 2 , Figure 6 and Figure 7 In some embodiments, the atomizing component 2 includes an atomizing tube 21 and a heating component 22, with the heating component 22 disposed within the cavity enclosed by the atomizing tube 21. The atomizing tube 21 has a liquid guiding hole 210 penetrating its wall. A buffer 3 is disposed around the atomizing tube 21, corresponding to the liquid guiding hole 210. Specifically, the liquid storage chamber 10, the buffer 3, the liquid guiding hole 210, and the heating component 22 are sequentially fluidly connected, meaning that liquid and gas can flow among the four components. The atomizing matrix in the liquid storage chamber 10 permeates sequentially through the buffer 3 and the liquid guiding hole 210 to the heating component 22. When energized, the heating component 22 generates heat to heat and atomize the atomizing matrix into an aerosol. The aerosol is exited from the atomizer through the atomizing tube 21 and the inner tube 12 of the mouthpiece for the user to inhale. The buffer 3 is fixed between the outer wall of the atomizing tube 21 and the groove wall of the receiving groove 42 corresponding to the second receiving area 422. Thus, the atomizing tube 21 and the atomizing seat 4 together serve to fix the buffer 3.
[0037] Please see Figure 2 , Figure 6 and Figure 7In some embodiments, the housing 1 comprises a shell 11 and a nozzle inner tube 12 connected together. The shell 11 encloses a cavity. The atomization assembly 2, the buffer 3 and the atomization seat 4 are arranged in the cavity. The nozzle inner tube 12 extends into the cavity from an end thereof distal to the shell 11. The atomization seat 4 is sealingly fitted with an inner wall surface of the shell 11. The atomization tube 21 is sleeved on an outer periphery of the nozzle inner tube 12. A lumen of the atomization tube 21 is in communication with a lumen of the nozzle inner tube 12. Surfaces of the shell 11 and the nozzle inner tube 12 facing each other, the buffer 3 and the atomization seat 4 together enclose the liquid storage cavity 10. That is, a surface of the shell 11 facing the nozzle inner tube 12, a surface of the nozzle inner tube 12 facing the shell 11, the buffer 3 and the atomization seat 4 together enclose the liquid storage cavity 10. Specifically, the shell 11 can comprise a shell main body 111 and a bottom cover 112 connected together. The shell main body 111 and the bottom cover 112 together enclose a cavity. The nozzle inner tube 12 is connected to an end of the shell main body 111 distal to the bottom cover 112. The nozzle inner tube 12 extends into the cavity from an end thereof distal to the shell main body 111. The shell main body 111 and the bottom cover 112 can be detachably connected, thereby facilitating installation of the atomization assembly 2, the buffer 3 and the atomization seat 4. The atomization tube 21 and the nozzle inner tube 12 can be in interference fit, so as to ensure sealing between the atomization tube 21 and the nozzle inner tube 12 and prevent leakage of the atomization substrate in the liquid storage cavity 10. Similarly, the atomization seat 4 and the shell main body 111 of the shell 11 can be in interference fit, so as to ensure sealing between the atomization seat 4 and the shell main body 111 and prevent leakage of the atomization substrate in the liquid storage cavity 10.
[0038] Referring to Figures 2 to 5 In some embodiments, the atomization seat 4 is substantially cylindrical. The atomization seat 4 has an outer peripheral surface arranged towards an inner wall surface of the housing 1. As Figure 2 shown in the illustrated embodiment, the outer peripheral surface of the atomization seat 4 refers to a surface of the atomization seat 4 facing the shell main body 111. The air exchange structure 41 comprises a plurality of air exchange grooves distributed on the outer peripheral surface of the atomization seat 4.
[0039] Further, as Figures 3 to 4As shown, in some embodiments, the air exchange structure 41 comprises a first air exchange groove 411 and a second air exchange groove 412. The first air exchange groove 411 is formed by partially recessing the outer circumferential surface of the atomization seat 4. The outer circumferential surface of the atomization seat 4 is provided with a plurality of protrusions 413 arranged at intervals, and the intervals between adjacent protrusions 413 form the second air exchange groove 412. Specifically, the first air exchange groove 411 is a ring-like long and narrow groove formed on the outer circumferential surface of the atomization seat 4. The first end 411A of the first air exchange groove 411 along its extension path penetrates the upper end surface of the atomization seat 4 (i.e., the end surface of the atomization seat 4 on the side facing the liquid storage cavity 10), thereby being in communication with the liquid storage cavity 10. The second end 411B of the first air exchange groove 411 along its extension path is in communication with the second air exchange groove 412. The second air exchange groove 412 is in communication with the atmospheric environment. Thus, the liquid storage cavity 10, the first air exchange groove 411, the second air exchange groove 412, and the atmospheric environment are sequentially in communication. The number of first air exchange grooves 411 is not limited and can be one or more. The number of protrusions 413 is at least two. An interval is formed between each adjacent two protrusions 413. The intervals between all protrusions 413 jointly define the second air exchange groove 412. As shown in the embodiment, the first air exchange groove 411 is located above the second air exchange groove 412; that is, the first air exchange groove 411 is closer to the liquid storage cavity 10 relative to the second air exchange groove 412. In other embodiments, the first air exchange groove 411 and the second air exchange groove 412 can be selectively arranged, that is, the air exchange structure 41 can only comprise the first air exchange groove 411 or only comprise the second air exchange groove 412. Figures 2 to 5 As shown in the embodiment, the first air exchange groove 411 is located above the second air exchange groove 412; that is, the first air exchange groove 411 is closer to the liquid storage cavity 10 relative to the second air exchange groove 412. In other embodiments, the first air exchange groove 411 and the second air exchange groove 412 can be selectively arranged, that is, the air exchange structure 41 can only comprise the first air exchange groove 411 or only comprise the second air exchange groove 412.
[0040] The first air exchange groove 411 and / or the second air exchange groove 412 can be a capillary channel. A capillary channel refers to a channel with a diameter small enough to allow the liquid therein to be subjected to capillary force, and the diameter is usually in the order of microns to nanometers. Thus, when the pressure in the liquid storage cavity 10 changes, the first air exchange groove 411 and / or the second air exchange groove 412 can be used to buffer the leaked atomization substrate, so as to avoid the atomization substrate from leaking directly to the outside of the shell 1 or contaminating other electronic components.
[0041] Please refer to Figure 2 , Figure 6 and Figure 7In some embodiments, the atomizer further comprises a sealing ring 5 arranged in the housing 1. The sealing ring 5 is sleeved on the outer circumferential surface of the atomizing seat 4 at the end close to the liquid storage cavity 10, and the outer ring 51 of the sealing ring 5 is in sealing cooperation with the inner wall surface of the housing 1. The outer ring 51 of the sealing ring 5 is the outer circumferential surface of the sealing ring 5. The sealing ring 5 seals the gap between the end of the atomizing seat 4 close to the liquid storage cavity 10 and the housing 1, so that the gas and liquid in the liquid storage cavity 10 can only flow into the air exchange groove and the buffer 3, preventing the liquid from leaking from the gap between the atomizing seat 4 and the housing 1, thereby causing the air exchange groove to lose the effect of buffering the liquid. Further, since the first air exchange groove 411 is a groove recessed with respect to the outer circumferential surface of the atomizing seat 4, the sealing ring 5 can be sleeved on the outer circumferential surface of the atomizing seat 4 at the position of the first air exchange groove 411, and the maximum transverse dimension of the sealing ring 5 can be approximately equal to the maximum transverse dimension of the protrusion 413, thereby facilitating the combination of the atomizing seat 4 and the sealing ring 5 to form a structure with uniform outer circumferential width. The sealing ring 5 can cover the opening of the first air exchange groove 411 towards the inner wall surface of the housing 1, and the first air exchange groove 411 is only connected to the liquid storage cavity 10 through one end of its extension path (i.e., the first end 411A penetrating the upper end surface of the atomizing seat 4), thereby ensuring that the liquid in the liquid storage cavity 10 can only enter the first air exchange groove 411 through the end of the extension path of the first air exchange groove 411. Specifically, the outer circumferential surface of the atomizing seat 4 can include a first region 431 and a second region 432 distributed along the vertical direction. The "vertical direction" can refer to the V-V direction in Figure 5 . The first region 431 is closer to the liquid storage cavity 10 than the second region 432. The first region 431 is located above the second region 432. The first air exchange groove 411 is located in the first region 431, and the protrusion 413 is arranged in the second region 432. The sealing ring 5 is sleeved on the first region 431 to cover the first air exchange groove 411.
[0042] Please refer to Figure 2 , Figure 6 and Figure 7 In some embodiments, the atomizer further comprises a liquid absorbing member 6 arranged in the housing 1, and the liquid absorbing member 6 is located on the side of the atomizing seat 4 away from the liquid storage cavity 10. The liquid absorbing member 6 can be used to absorb the liquid atomized substrate that drips from the atomizing assembly 2 and the liquid atomized substrate that flows out from the air exchange structure 41, preventing the atomized substrate from leaking to the outside of the housing 1 or contaminating other electronic components. The liquid absorbing member 6 can be made of a fiber material, which can include one or more combinations of natural cotton, bamboo fiber, glass fiber, PA (polyamide, commonly known as nylon), PET (polyethylene terephthalate, commonly known as polyester), and CA (cellulose acetate). Figure 2 , Figure 6 and Figure 7In the illustrated embodiment, the liquid absorbing member 6 can be mounted on the surface of the bottom cover 112 facing the shell main body 111.
[0043] The atomization assembly 2 comprises a heating assembly 22, which comprises a liquid guide 221 and a heating body 222 arranged on the liquid guide 221, and the liquid guide 221 is in fluid communication with the buffer 3. In some embodiments, the liquid guide 221 can be in a cylindrical shape with both ends penetrating through, the outer circumferential surface of which is in contact with the atomization tube 21, and the heating body 222 is fixed on the inner circumferential surface of the liquid guide 221 by means of bonding, embedding, printing or the like. The liquid guide 221 can be made of a fiber material, which can include one or more combinations of natural cotton, bamboo fiber, glass fiber, PA (polyamide, commonly known as nylon), PET (polyethylene terephthalate, commonly known as polyester), CA (cellulose acetate) of textile. Compared with hard porous materials such as ceramics, the liquid guide 221 of the fiber material belongs to soft materials, and the liquid atomization substrate in the storage cavity 10 gradually penetrates to the liquid guide 221 through the buffer 3 and the liquid guide hole 210, and then penetrates to the position of the heating body 222 through the liquid guide 221. The heating body 222 generates heat in the energized state, heats and atomizes the atomization substrate to generate aerosol, and the aerosol is sequentially guided out through the atomization tube 21 and the inner tube 12 of the mouthpiece for the user to inhale.
[0044] In some embodiments, the present application also provides an electronic atomization device, which comprises the atomizer of any one of the above embodiments, and a power supply unit (not shown) connected to the atomizer. The power supply unit provides power for the atomizer and can be used to control the operation of the atomizer. Specifically, the power supply unit can comprise an electric core capable of storing and releasing electric energy, and the electric core is electrically connected to the heating body 222 of the heating assembly 22 of the atomization assembly 2 of the atomizer, thereby providing power for the heating body 222.
[0045] The above application of specific examples to the present application is only used to help understand the present application and does not limit the present application. For those skilled in the art to which the present application belongs, according to the idea of the present application, a number of simple deductions, deformations or substitutions can be made.
