[0045] Please refer to Figures 1 to 7 , an embodiment of the present application provides an electronic atomization device, which can be used to heat and atomize a matrix to generate an aerosol for use; the electronic atomization device includes a housing assembly 100, an electronic control assembly 200, a liquid storage assembly 300, an atomization assembly 400, and other functional components as required, which will be specifically described below.

[0046] Please refer to Figure 1 and Figure 2, the housing assembly 100 can be understood as a collection of related structural components that constitute the basic structural framework and outer contour of the electronic atomization device. For example, the housing assembly 100 can be a hollow structure formed by combining multiple structural components. By installing the electronic control assembly 200, the liquid storage assembly 300, etc. on the housing assembly 100, a complete electronic atomization device can be formed. With the help of the housing assembly 100, the electronic atomization device can be carried, moved, held, operated, and used, etc.

[0047] Please refer to Figure 1 and Figure 2 , the electronic control assembly 200 is disposed on the housing assembly 100 and is electrically connected to the atomization assembly 400. The electronic control assembly 200 is mainly used to support the realization of some or all functions of the electronic atomization device. For example, it controls the start and stop of heating of the atomization assembly 400, adjusts the heating power of the atomization assembly 400, and displays the status information of the electronic atomization device, etc.

[0048] Please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 , the liquid storage assembly 300 is disposed inside the housing assembly 100. The liquid storage assembly 300 has an atomization channel 300a and a plurality of liquid storage chambers 300b for storing the same or different atomization matrices. Among them, the plurality of liquid storage chambers 300b are arranged side by side and do not communicate with each other. For the convenience of distinction and description, the arrangement direction of the plurality of liquid storage chambers 300b is defined as the first direction. The atomization channel 300a is arranged through the liquid storage assembly 300 along the first direction, and each of the plurality of liquid storage chambers 300b is communicated with the atomization channel 300a. Using the communication relationship between the atomization channel 300a and the liquid storage chamber 300b, structural support can be provided for each liquid storage chamber 300b to enter the atomization assembly 400.

[0049] Please refer to Figures 1 to 6 , the atomization assembly 400 is disposed in the atomization channel 300a and is mainly used to heat and atomize the atomization matrix entering the atomization assembly 400 from the liquid storage chamber 300b to generate aerosol in the atomization channel 300a. The atomization assembly 400 includes a first electrode lead 420, a plurality of heating elements 410, and a plurality of second electrode leads 430.

[0050] Among them, the heating element 410 can be a structure made of electrothermal material, such as a heating wire structure, a heating mesh structure, etc. Each heating element 410 has a first electrode pin and a second electrode pin. The plurality of heating elements 410 are arranged side by side and spaced apart along the first direction in the atomization channel 300a, and at least one heating element 410 is arranged at the area position of the atomization channel 300a corresponding to each liquid storage chamber 300b.

[0051] The first electrode pins of multiple heating elements 410 share a first electrode lead 420 and are electrically connected to the electronic control component 200, while the second electrode pins of multiple heating elements 420 are each electrically connected to the electronic control component 200 through a corresponding second electrode lead 430; for example, the first electrode lead 420 and the second electrode lead 430 are connected to the electronic control component 200 after being led out from within the atomization channel 300a.

[0052] On the one hand, by utilizing the correspondence between the heating element 410 and the liquid storage chamber 300b, the heating element 410 is mainly used to heat and atomize the atomization matrix from the corresponding liquid storage chamber 300b, so that a partitioned or segmented heating structure can be formed inside the electronic atomization device, which is beneficial to achieving sufficient heating and atomization of the atomization matrix; at the same time, the liquid storage chamber 300b can provide an abundant atomization matrix for its corresponding heating element 410, which can not only avoid the influence of the heating element 410 on the quality of the aerosol due to phenomena such as dry burning, but also effectively improve the service life of the heating element 410 or the atomization assembly 400.

[0053] On the other hand, each heating element 410 can respectively form a power supply circuit with the electronic control component 200 through the first electrode lead 420 and the corresponding second electrode lead 430, so that the electronic control component 200 can selectively supply power to one or more of the multiple heating elements 410. It can also be understood that the electronic control component 200 can independently control the multiple heating elements 410; in this way, it can not only endow the electronic atomization device with multiple heating modes to adjust the generation amount or taste of the aerosol, etc., to meet the actual needs of users, but also further avoid phenomena such as dry burning of the heating element 410.

[0054] Exemplarily, with the help of the electronic control component 200, the heating element 410 corresponding to a certain liquid storage chamber 300b can be selectively enabled to heat and atomize the atomization matrix provided by the liquid storage chamber 300b, so as to generate a single-flavor aerosol; with the help of the electronic control component 200, the heating elements 410 corresponding to some or all of the liquid storage chambers 300b can also be selectively enabled, so that a mixed-flavor aerosol can be generated or the generation amount of the aerosol can be increased. In addition, when the atomization matrix in a certain liquid storage chamber 300b is exhausted, the power supply to the heating element 410 corresponding to the liquid storage chamber 300b can be paused to avoid dry burning of the heating element 410 due to continuous heating.

[0055] In other embodiments, the electrical connection relationship between the multiple heating elements 410 and the electronic control assembly 200 may also adopt other suitable forms. For example, the first electrode pins and the second electrode pins of the multiple heating elements 410 are respectively electrically connected to the electronic control assembly 200 through a corresponding first electrode lead 420 and a second electrode lead 430, thereby equivalent to forming a power supply circuit for the multiple heating elements 410 in parallel with the electronic control assembly 200. Through the functional configuration of the electronic control assembly 200, independent control of the multiple heating elements 410 can also be achieved. For another example, the multiple heating elements 410 can also be electrically connected to the electronic control assembly 200 in series. At this time, with the partition or segmented heating structure formed by the heating elements 410, the atomization matrix provided by the corresponding liquid storage chamber 300b can be fully heated, and the phenomenon of dry burning can be avoided because each heating element 410 can contact sufficient atomization matrix; all these are not elaborated here.

[0056] In one embodiment, please refer to Figure 1 、 Figures 3 to 6 , the atomization assembly 400 further includes an adsorbent 440. The adsorbent 440 is inserted into the atomization channel 300a along the first direction and covers the connection between the atomization channel 300a and each liquid storage chamber 300b, mainly for adsorbing the atomization matrix entering the atomization channel 300a from the liquid storage chamber 300b; the heating element 410 is in contact with the adsorbent 440 so as to generate an aerosol by heating the atomization matrix adsorbed by the adsorbent 440.

[0057] Exemplarily, the adsorbent 440 is an integral tubular structure made of a material with capillary force such as porous ceramic, cotton fiber, metal fiber, non-woven fabric, etc. The adsorbent 440 is inserted into the atomization channel 300a along the first direction, and the connection between the atomization channel 300a and the liquid storage chamber 300b is sealed by the outer peripheral surface of the adsorbent 440; correspondingly, the heating element 410 is generally a mesh structure attached to the inner peripheral surface of the adsorbent 440, and the multiple heating elements 410 are arranged side by side and spaced apart inside the adsorbent 440 along the first direction.

[0058] Thus, due to the capillary force of the adsorbent 440, the atomization matrix entering the atomization channel 300a from the liquid storage chamber 300b can be attracted and adsorbed, so that the heating element 410 can heat the atomization matrix adsorbed by the adsorbent 440; at the same time, by using the adsorbent 440 to seal the connection between the atomization channel 300a and the liquid storage chamber 300b, leakage of the atomization matrix in the liquid storage chamber 300b can be avoided. In addition, by arranging the multiple heating elements 410 on the same adsorbent 440, the assembly efficiency of the atomization assembly 400 can be effectively improved, and the structural integrity and stability of the atomization device 400 can be enhanced.

[0059] In another embodiment, the adsorbent 440 may also be a plurality of tubular structures made of a material with capillary force or strong liquid adsorption ability. The plurality of tubular structures are arranged side by side in the atomization channel 300a in the first direction (for example, arranged at intervals or in continuous contact), and the plurality of tubular structures correspond to the plurality of liquid storage chambers 300b one by one. The tubular structure covers the connection between its corresponding liquid storage chamber 300b and the atomization channel 300a, and at least one heating element 410 is in contact with each tubular structure. By setting the adsorbent 440 as a multi-segment tubular structure, the adsorbent 440 can adsorb the atomization matrix from the corresponding liquid storage chamber 300b, avoiding the mixing of different atomization matrices in the adsorbent 440 or the atomization channel 300a. In this way, by selectively activating the corresponding heating element 410, the purity of the aerosol flavor can be effectively guaranteed.

[0060] In other embodiments, according to the structural form of the adsorbent 440 or the functional configuration requirements of the electronic atomization device, etc., the heating element 410 may adopt other suitable structures. For example, the heating element 410 may be a heating wire structure wound around the adsorbent 440, or a heating mesh structure in contact with the surface of the adsorbent 440, or a columnar, sheet-like or other heating structures embedded in the adsorbent 440; all these are not elaborated here.

[0061] In one embodiment, please refer to Figure 1 、 Figure 3 、 Figure 5 and Figure 6 ,the atomization assembly 400 further includes a fixing member 450, which is inserted into the air inlet end of the atomization channel 300a, mainly used to limit and fix the adsorbent 440 (together with the heating element 410) in the atomization channel 300a. On the one hand, it prevents the atomization assembly 400 from coming out of the atomization channel 300a, and on the other hand, it limits and positions the heating element 410 in the area corresponding to the liquid storage chamber 300b.

[0062] Exemplarily, the fixing member 450 may be a sleeve structure made of a soft material such as silica gel or rubber. The fixing member 450 is inserted into the atomization channel 300a in an interference fit manner and abuts against the adsorbent 440 in the first direction; the fixing member 450 may also be a convex structure formed on the channel wall at the air inlet end of the atomization channel 300a, which forms a structural limitation on the adsorbent 440 and the heating element 410 by abutting against the adsorbent 440. In some embodiments, the fixing member 450 may also be provided alone or simultaneously at the air outlet end of the atomization channel 300a, which is not elaborated here.

[0063] In one embodiment, please refer to Figure 1 and Figure 5, the liquid storage assembly 300 includes a sleeve member 310, a sealing member 320, a partition member 330, and a shaft pipe member 340; wherein, the sleeve member 310 extends along a first direction and is arranged inside the housing assembly 100; the sealing member 320 is arranged at opposite ends of the sleeve member 310 in the first direction to seal the pipe orifices of the sleeve member 310; the partition member 330 is arranged inside the sleeve member 310, and the partition member 330 and the sealing member 320 are spaced opposite to each other in the first direction; the shaft pipe member 340 is arranged inside the sleeve member 310, and the shaft pipe member 340 penetrates through the partition member 330 and the sealing member 320 along the first direction.

[0064] Exemplarily, the sealing member 320 can be a columnar structure made of soft materials such as silica gel and rubber. At least part of the sealing member 320 is inserted into the port of the sleeve member 310 in an interference fit manner, so as to seal and close the pipe orifices of the sleeve member 310; and the shaft pipe member 340 is arranged to penetrate through the sealing member 320 in an interference fit manner to eliminate the structural gap between the shaft pipe member 340 and the sealing member 320.

[0065] Exemplarily, the partition member 330 can be a columnar or plate-like structure made of soft materials such as silica gel and rubber. The partition member 330 is inserted into the sleeve member 310 in an interference fit manner, and the shaft pipe member 340 penetrates through the partition member 330 in an interference fit manner; or the partition member 330 is an annular plate structure protruding from the inner peripheral surface of the sleeve member 310 and surrounding the shaft pipe member 340, and the shaft pipe member 340 penetrates through the partition member 330.

[0066] Thus, by using the partition member 330 to separate the structural space between the inner peripheral surface of the sleeve member 310 and the outer peripheral surface of the shaft pipe member 340 along the first direction, and by virtue of the structural arrangement form in which the partition member 330 and the sealing member 310 are spaced opposite to each other in the first direction, the inner space of the sleeve member 310 can be separated into a plurality of liquid storage chambers 300b that are not communicated with each other and are arranged side by side in the first direction, that is: in the first direction, the liquid storage chambers 300b are formed between adjacent partition members 330 and sealing members 320.

[0067] The pipe body space of the shaft pipe member 340 can be used as an atomization channel 300a for accommodating and placing the atomization assembly 400. At the same time, one or more drainage ports 300c for communicating the liquid storage chamber 300b with the atomization channel 300a are provided on the pipe wall of the shaft pipe member 340 (for example, at the regional positions corresponding to each liquid storage chamber 300b), so that the atomization matrix in the liquid storage chamber 300b can enter the atomization assembly 400 (specifically such as the adsorption member 440) through the corresponding drainage port 300c.

[0068] In specific implementation, the number of the partition members 330 can be one or more. For example, one partition member 330 is arranged inside the sleeve member 310, so that two non-communication and side-by-side arranged liquid storage chambers 300b can be formed inside the liquid storage assembly 300. Another example is that two partition members 330 spaced relatively to each other in the first direction are arranged inside the sleeve member 310, so that three liquid storage chambers 300b can be formed inside the liquid storage assembly 300, that is, liquid storage chambers 300b are formed between the adjacent partition members 330 and the closing member 320 and between the adjacent two partition members 330.

[0069] Based on this, the overall structural framework of the liquid storage assembly 300 is built by combining the sleeve member 310, the closing member 320, the shaft pipe member 340, etc., which is convenient for adjusting the structure of the liquid storage assembly 300, such as adjusting the size of the liquid storage assembly 300 in the first direction, adjusting the number of the liquid storage chambers 300b, etc. At the same time, it is also convenient for assembling and forming and disassembling and maintaining the liquid storage assembly 300, creating favorable conditions for reducing the manufacturing and use costs of the electronic atomization device.

[0070] In one embodiment, please refer to Figure 1 and Figure 5 , the partition member 330 and the sleeve member 310 adopt an integral structure; wherein, the partition member 330 is generally an annular plate structure protruding from the inner peripheral wall of the sleeve member 310 around the shaft pipe member 340, and the number of the partition members 330 can be one, or two, three or other more numbers.

[0071] In this way, the internal space of the sleeve member 310 can be separated by the partition member 330, so that liquid storage chambers 300b can be formed on both sides of each partition member 330 facing away from each other in the first direction; and the number of components of the liquid storage assembly 300 can be reduced, which is beneficial to improving the stability and compactness of the overall structure of the liquid storage assembly 300.

[0072] In one embodiment, please refer to Figure 6 , the sleeve member 310 adopts a split combination structure, which includes a plurality of pipe body parts 310a, such as two, three or other more numbers of pipe body parts 310a; the plurality of pipe body parts 310a are coaxially arranged side by side in the first direction, and the partition member 330 is fixed between the adjacent two pipe body parts 310a in the form of blocking the pipe orifices of the pipe body parts 310a.

[0073] Exemplarily, the partition member 330 is a plate-shaped structure made of a soft material such as silica gel or rubber, and the partition member 330 has a partition part 330a and a flange part 330b; wherein, the flange part 330b protrudes from the outer peripheral surface of the partition part 330a around the partition part 330a, and the thickness dimension of the flange part 330b in the first direction is smaller than the thickness dimension of the partition part 330a in the first direction.

[0074] In this way, by clamping and fixing the flange portion 330b between the end faces of the pipe orifices of two adjacent pipe body portions 310a, the partition portion 330a can cover the pipe orifice of the pipe body portion 310a, so that a corresponding liquid storage chamber 300b is formed inside each pipe body portion 310a by means of two adjacent partition portions 330a in the first direction or the partition portion 330a and the adjacent sealing member 320.

[0075] Exemplarily, the partition member 330 is a columnar structure made of a soft material such as silica gel or rubber. The opposite ends of the partition member 330 in the first direction are inserted into the corresponding pipe body portion 310a in an interference fit manner. Thus, the partition member 330 can not only structurally fix two adjacent pipe body portions 310a, but also cooperate with the sealing member 320 or cooperate with two adjacent partition members 330 to form a corresponding liquid storage chamber 300b inside each pipe body portion 310a.

[0076] Exemplarily, the partition member 330 can also be a cover plate-shaped or columnar structure made of other materials (such as hard materials). The partition member 330 structurally fixes two adjacent pipe body portions 310a by means of bonding, welding, clamping, plugging, etc., and then forms a corresponding liquid storage chamber 300b inside each pipe body portion 310a. During specific implementation, structural gaps between the partition member 330 and the pipe body portion 310a can be eliminated by accessories such as sealing rings and gaskets to ensure the sealing performance of the liquid storage chamber 300b.

[0077] In summary, by setting the sleeve member 310 into a split structure and fixing the partition member 330 between adjacent pipe body portions 310a in a detachable manner, the overall structural dimensions of the liquid storage assembly 330 can be flexibly adjusted to form a liquid storage assembly 300 with different numbers of liquid storage chambers 300b. At the same time, the structures of the components are simple and convenient to process and manufacture, which is beneficial to the disassembly, maintenance and assembly of the liquid storage assembly 300, and can also reduce the manufacturing and use costs of the liquid storage assembly 300 or the electronic atomization device.

[0078] In some embodiments, the liquid storage assembly 300 can also be assembled in other structural forms. For example, the sealing member 320 is omitted and the sleeve member 310 adopts a cup-shaped structure. Specifically, please refer to Figure 7, the liquid storage assembly 300 includes two cup members 350. For the convenience of distinction and description, the relatively closed end of the cup member 350 is defined as the bottom end of the cup member 350, and the open end of the cup member 350 is defined as the cup mouth end of the cup member 350; wherein, the cup mouth ends of the two cup members 350 face each other in the first direction, the partition member 330 is arranged between the two cup members 350, and the partition member 330 covers the cup mouth ends of the two cup members 350; and the shaft pipe member 340 is arranged inside the cup member 350, and the shaft pipe member 340 penetrates through the bottom ends of the two cup members 350 and the partition member 330 along the first direction.

[0079] Exemplarily, the contour edge of the partition member 330 is clamped and fixed between the end faces of the cup mouth ends of the two cup members 350; Exemplarily, the partition member 330 can be inserted into the two cup members 350 through the cup mouth end in an interference fit manner.

[0080] Thus, by closing the cup mouth ends of the two cup members 350 with the partition member 330, a corresponding liquid storage chamber 300b can be formed inside each cup member 350. It can also be understood that the two liquid storage chambers 300b of the liquid storage assembly 300 are located on the two sides of the partition member 330 facing away from each other in the first direction. By combining the cup member 350 and the partition member 330 to form the basic structural framework of the liquid storage assembly 300, the number of components of the liquid storage assembly 300 can be further reduced (for example, saving the closing member 320), which is beneficial to improving the integrity and stability of the structure of the liquid storage assembly 300.

[0081] In some embodiments, based on the consideration of the number of the liquid storage chambers 300b, a ring plate structure spaced relative to the partition member 330 can also be arranged inside the cup member 350, or the number of the partition members 330 can be increased, so that a part of the partition members 330 are inserted into the cup member 350 in an interference manner; in this way, more liquid storage chambers 300b can be formed inside the cup member 350.

[0082] In one embodiment, please refer to Figure 1 , a first accommodation cavity 100a, a second accommodation cavity 100b and an air outlet channel 100c are formed inside the housing assembly 100. The first accommodation cavity 100a and the second accommodation cavity 100b are arranged side by side and communicated in the first direction. The air outlet channel 100c is communicated and arranged on the side of the first accommodation cavity 100a away from the second accommodation cavity 100b in the first direction; wherein, the liquid storage assembly 300 is arranged in the first accommodation cavity 100a, the electronic control assembly 200 is arranged in the second accommodation cavity 100b, and the air outlet end of the atomization channel 300a is hermetically communicated with the air outlet channel 100c, while the air inlet end of the atomization channel 300a is communicated with the second accommodation cavity 100b or the outside of the housing assembly 100.

[0083] By accommodating the liquid storage component 300 and the electronic control component 200 in the first direction and placing them inside the housing component 100, the electronic control component 200 can be used to press the liquid storage component 300 to firmly restrict the liquid storage component 300 in the housing component 100, and keep the atomization channel 300a and the air outlet channel 100c sealed and connected; in this way, after the airflow enters the atomization channel 300a, it can carry the generated aerosol and discharge it from the electronic atomization device through the air outlet channel 100c. for use; for example, by pressing the closing piece 320 or the cup bottom end of the cup body 350 located on the air inlet end side of the atomizing channel 300a along the first direction toward the side where the air outlet channel 100c is located through the electronic control component 200, the closing piece 320 or the cup bottom end of the cup body 350 located on the air outlet end side of the atomizing channel 300a can be tightly fitted to the inner wall of the shell component 100, thereby ensuring that the atomizing channel 300a is sealed and connected with the air outlet channel 100c.

[0084] It should be noted that Figure 1 The bold dashed line in the figure merely indicates the approximate boundary between the first accommodating cavity 100 a and the second accommodating cavity 100 b , and does not indicate the structural configuration of the first accommodating cavity 100 a , the second accommodating cavity 100 b or the housing assembly 100 .

[0085] In other embodiments, based on the design requirements of the overall structural architecture of the electronic atomization device, the structural structure of the shell component 100 can also be adaptively adjusted, so that the liquid storage component 300 and the electronic control component 200 are arranged in the shell component 100 in other forms; for example, the liquid storage component 300 and the electronic control component 200 are arranged side by side in a direction perpendicular to the first direction; for example, the liquid storage component 300 and the electronic control component 200 are arranged in different shell components 100, and a complete electronic atomization device is formed by combining and connecting the two shell components 100, and an electrical connection relationship is established between the electronic control component 200 and the atomization component 400; all these will not be elaborated here.

[0086] In one embodiment, see Figure 1 , Figure 5 and Figure 6 The liquid storage component 300 also includes a liquid absorbent member 360, which can be a structure made of cotton material or other materials with strong adsorption capacity for liquid, such as a ring-shaped or tubular structure with a through-hole structure; the liquid absorbent member 360 is arranged at the connection between the air outlet channel 100c and the atomization channel 300a, for example, a receiving groove (not marked in the figure) is arranged on the closing member 320 located on the air outlet end side of the atomization channel 300a, and the receiving groove is located on the side of the closing member 320 away from the sleeve member 310 in the first direction, and the liquid absorbent member 360 is arranged in the receiving groove.

[0087] Therefore, the liquid formed in the air outlet channel 100c (for example, liquid formed by aerosol condensation) can be absorbed by the liquid absorbent 360, thereby preventing the liquid from leaking to the outside of the electronic atomization device through the air outlet channel 100c, thereby improving the user experience of the electronic atomization device.

[0088] In some embodiments, a liquid absorption component 360 may also be provided on the air inlet end side of the atomization channel 300a. For example, a liquid absorption component 360 may be provided on the sealing component 320 located on the air inlet end side of the atomization channel 300a. The liquid absorption component 360 may be used to prevent liquid (such as liquid formed by condensation of the atomization matrix or aerosol) from leaking from the atomization channel 300a to the interior of the shell assembly 100 or the electronic control assembly 200.

[0089] It is understandable that in some embodiments, the absorbent member 360 can be arranged at one end or two opposite ends of the sleeve member 310 in the first direction, and the absorbent member 360 is located on a side of the closure member 320 away from the sleeve member 310 in the first direction.

[0090] In one embodiment, see Figure 1 and Figure 2 The shell assembly 100 includes a first shell 110 and a second shell 120, which are connected along a first direction to form a first accommodating cavity 100a and a second accommodating cavity 100b between the first shell 110 and the second shell 120; illustratively, the first shell 110 and the second shell 120 can be connected and fixed by means of interference fit, snap-fit, bonding, welding, etc.; at the same time, the air outlet channel 100c is arranged at one end of the first shell 110 away from the second shell 120 in the first direction.

[0091] The electric control component 200 can be fixedly arranged in the second housing 120, so that in the process of assembling the electronic atomization device, the liquid storage component 300 (together with the atomization component 400) can be first arranged in the first housing 110, and then when the second housing 120 is installed in the first housing 110, the electric control component 200 can be used to press the liquid storage component 300, so that the atomization channel 300a and the air outlet channel 100c are sealed and connected. At the same time, by arranging the electric control component 200 and the liquid storage component 300 on different housings, it is convenient to disassemble and maintain the electric control component 200 and even the entire electronic atomization device.

[0092] In one embodiment, see Figure 1, the electronic control component 200 includes a circuit board 210, a microphone component 220, and a power supply cell 230; wherein, the circuit board 210 can be fixedly locked in the second housing 120 by screws or the like, and the heating element 410 is electrically connected to the circuit board 210; the microphone component 220 is disposed on a side of the circuit board 210 away from the air outlet channel 100c in the first direction, and the microphone component 220 is electrically connected to the circuit board 210; the power supply cell 230 is fixedly disposed on a side of the circuit board 210 facing away from the microphone component 220 in the first direction (for example, the power supply cell 230 is adhered to the circuit board 210), and the power supply cell 230 is electrically connected to the circuit board 210.

[0093] Thus, the characteristics such as the relatively large volume size of the power supply cell 230 can be utilized as a structural member for the electronic control component 200 to press against the liquid storage component 300, so as to firmly limit the liquid storage component 300 in the first housing 110 through a pressing closure 320 or the like, and to connect the atomization channel 300a to the air outlet channel 300b; meanwhile, the microphone component 220 can be used as a functional element to trigger the heating of the heating element 410. By sensing the air pressure change information inside the housing assembly 100 or the corresponding structural space through the microphone component 220, information support is provided for the circuit board 210 to control the start and stop of heating of the heating element 410; it can be understood that the circuit board 210 can control the heating element 410 in response to the sensing information of the microphone component 220.

[0094] It should be noted that the atomization matrix can be a liquid medium such as physiological saline, liquid medicine, liquid extract, e-liquid, etc.; exemplarily, the component composition of a typical atomization matrix is propylene glycol, glycerol, nicotine, flavor substances, etc. The atomization matrix can be directly filled and stored in the liquid storage chamber 300b, or adsorbed and stored in a liquid storage material body made of cotton material or porous material. By placing the liquid storage material body in the liquid storage chamber 300b, the storage of the atomization matrix is realized. It can be understood that the atomization matrix or the liquid storage material body storing the atomization matrix can be a component of the electronic atomization device or a consumable used in cooperation with the electronic atomization device; that is to say, the atomization matrix does not constitute a limitation to the electronic atomization device of this embodiment.

[0095] The above uses specific examples to elaborate on the present application, which is only for helping to understand the present application and is not intended to limit the present application. For those skilled in the technical field to which the present application pertains, based on the idea of the present application, several simple deductions, deformations or substitutions can also be made.
