Description

Technical Field

[0001] This application relates to the field of atomizing device technology, and in particular to a liquid reservoir and an electronic atomizing device including the liquid reservoir. Background Technology

[0002] An atomizing device is an electronic product that atomizes a liquid matrix to produce an aerosol for users to inhale. It generally consists of a reservoir, an atomizer, and a power supply. The reservoir and the atomizer are connected, and the atomizer is connected to the reservoir. The atomizer heats the liquid matrix flowing from the reservoir to the atomizer to atomize it and produce an aerosol. The power supply is electrically connected to the atomizer and is used to provide power to the atomizer.

[0003] Current technology provides an electronic atomizing device comprising a separate liquid reservoir and an atomizer, with the atomizer not pre-filled with a liquid matrix. Before use, the two components need to be connected to allow the liquid matrix from the reservoir to be introduced into the atomizer. The inventors of this application discovered that, after the atomizer is assembled with the liquid reservoir, the liquid matrix flows slowly from the reservoir into the atomizer. This slow flow prevents timely filling of the atomizer after assembly, causing users to be unable to use the atomizing device immediately or experience insufficient liquid supply during initial inhalation, thus affecting the user experience. Utility Model Content

[0004] This application provides a liquid reservoir, which mainly solves the technical problem that when existing liquid reservoirs are assembled onto atomizers, the liquid matrix in the liquid reservoir is introduced into the atomizer at a slow speed, thus preventing users from using the atomizer in a timely manner.

[0005] To address the aforementioned technical problems, this application provides a liquid reservoir, comprising: a housing assembly, a cover assembly, and a liquid outlet. The cover assembly is at least partially disposed within the housing assembly. The cover assembly is movable relative to the housing assembly between a preset first position and a preset second position. At least a portion of the housing assembly and the cover assembly together define a receiving space for containing a liquid matrix capable of being atomized. The liquid outlet provides a liquid outlet for the liquid matrix to be output from the liquid reservoir. When the cover assembly moves to the preset first position, it blocks the liquid outlet to isolate the receiving space from the external environment. When the cover assembly moves to the preset second position, it opens the liquid outlet and compresses the volume of the receiving space to drive the liquid matrix into the liquid outlet.

[0006] Optionally, the cover assembly includes a first cover, a second cover, and a connector. One end of the connector is connected to the first cover, and the other end of the connector is connected to the second cover. The first cover is movably connected to the housing assembly, and the second cover is located within the receiving space. The second cover is used to cover or open the liquid outlet.

[0007] Optionally, the reservoir includes a limiting member for limiting the maximum travel of the cover assembly as it moves from the first position to the second position.

[0008] Optionally, the reservoir further includes an elastic element for driving the cap assembly back from the second position to the first position.

[0010] Optionally, the partition wall extends toward the wall surface of the first portion with a limiting boss, the limiting boss being used to abut against the first cover to limit the maximum travel of the cover assembly when it moves from the first position to the second position.

[0011] Optionally, the first cover is provided with a sliding hole communicating with the outside, and the housing assembly further includes a conduit extending from the partition wall toward the first cover and through the sliding hole, the liquid outlet being defined by the conduit.

[0012] Optionally, the cover assembly includes a first seal, which is fitted onto the conduit, with the outer wall of the first seal abutting against the inner wall of the sliding hole to allow the conduit to slide in a sealed manner within the sliding hole.

[0013] Optionally, the reservoir further includes a compression spring sleeved on the connector, the compression spring being elastically compressed between the first cover and the partition wall.

[0014] Optionally, the cover assembly includes a screw connector, the other end of the connector is provided with a screw hole, the second cover is provided with a first through hole, and the screw connector passes through the first through hole and is screwed into the screw hole.

[0015] Optionally, the partition wall is provided with a sealing groove, the liquid outlet extends to the bottom of the sealing groove, the cover assembly includes a second sealing member, at least a portion of the second sealing member is accommodated in the sealing groove, the second sealing member is provided with a second through hole, the second through hole communicates with the liquid outlet, and the second sealing member is used to seal the gap between the second cover and the partition wall when the second cover covers the liquid outlet.

[0016] This application provides an electronic atomizing device, including: an atomizer and the aforementioned liquid reservoir, wherein the liquid reservoir can be assembled to the atomizer, and when the liquid reservoir is assembled to the atomizer, the atomizer can drive the cover assembly to move to a second position, thereby promoting the flow of a portion of the liquid matrix in the receiving space into the atomizer through the liquid outlet.

[0017] The beneficial effects of this application are as follows: Unlike existing technologies, this application provides a liquid reservoir and an electronic atomizing device, including a housing assembly, a cover assembly, and a liquid outlet. The cover assembly is at least partially disposed within the housing assembly. The cover assembly is movable relative to the housing assembly between a first position and a second position. At least a portion of the housing assembly and the cover assembly together enclose a receiving space for containing a liquid matrix capable of being atomized. The liquid outlet provides a liquid outlet for the liquid matrix to overflow from the reservoir. When the cover assembly moves to the first position, it blocks the liquid outlet, isolating the receiving space from the external environment. When the cover assembly moves to the second position, it opens the liquid outlet and compresses the volume of the receiving space, driving the liquid matrix into the liquid outlet. With the above structure, in this embodiment of the application, the cover assembly can be moved from a preset first position to a preset second position by the atomizer during the assembly of the liquid reservoir and the atomizer. While compressing the volume of the receiving space, the liquid matrix built into the receiving space is squeezed into the atomizer from the liquid outlet. This allows the atomizer and the liquid reservoir to be directly inhaled after assembly, without the user having to wait, thus improving the user experience. Attached Figure Description

[0037] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0038] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0039] In existing electronic atomizing devices, after the liquid reservoir is assembled with the atomizer, the user needs to wait for the liquid matrix in the reservoir to flow into the atomizer and then be absorbed by the liquid guiding component in the atomizer, or manually assist the liquid matrix to flow into the atomizer. The operation is cumbersome and the waiting time is long, making it impossible to achieve the immediate use of the electronic atomizing device after the liquid reservoir and atomizer are assembled.

[0040] To address the aforementioned problems, this application provides a liquid reservoir 100. Please refer to [link to relevant documentation]. Figures 1 to 4 The liquid reservoir 100 includes a cover assembly 1 and a housing assembly 2, wherein the cover assembly 1 is at least partially disposed within the housing assembly 2, the cover assembly 1 is movable relative to the housing assembly 2 between a preset first position L1 and a preset second position L2, and the housing assembly 2 and the cover assembly 1 together define a receiving space S, thereby the volume of the receiving space S is variable by the movement of the cover assembly 1 between the preset first position L1 and the preset second position L2. Specifically, the volume of the receiving space S changes linearly when the cover assembly 1 moves from the preset first position L1 to the preset second position L2, and the receiving space S is used to contain a liquid matrix that can be atomized.

[0041] It should be noted that the liquid matrix may contain a liquid containing tobacco-containing substances with volatile tobacco aroma components, or it may contain a liquid containing non-tobacco substances. The liquid matrix may contain water, pharmaceutical solutions, solvents, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures, etc. Fragrances may include areca nut extract, menthol, peppermint, spearmint oil, various fruit flavorings, etc., but are not limited to these. Flavorings may contain ingredients that can provide the user with various fragrances or flavors. Vitamin mixtures may be mixtures containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited to these. Based on the different properties of the liquid matrix, the reservoir 100 can be used in different fields, such as medical applications and electronic aerosol nebulization.

[0042] The fitting relationship between the cover assembly 1 and the housing assembly 2 described above is briefly explained here. Please refer to [link / reference]. Figure 3 and Figure 4 When the housing assembly 2 moves to the preset first position L1, the cover assembly 1 seals the liquid outlet 3, isolating the containment space S from the external environment, thus forming a relatively closed space. When the cover assembly 1 moves to the second position L2, the cover assembly 1 opens the liquid outlet 3 and compresses the volume of the containment space S to drive the liquid matrix into the liquid outlet 3. It can be understood that when the cover assembly 1 moves from the preset first position L1 to the preset second position L2, the volume of the containment space S changes. When the liquid matrix stored in the containment space S is squeezed out of the containment space S, it forms a high-speed jet of liquid at the liquid outlet 3. This jet of liquid enters the atomizer, thereby wetting the liquid guide of the atomizer connected to the liquid reservoir 100. The user can start inhaling while assembling the atomizer and the liquid reservoir 100, improving the user experience.

[0043] Understandably, since the liquid matrix needs to be exported from the containment space S to the atomizer assembled therewith for atomization, a liquid outlet 3 needs to be opened on the reservoir 100. The liquid outlet 3 is connected to the containment space S and is used to provide a liquid outlet for the liquid matrix to be output from the reservoir 100.

[0044] In this embodiment, the shell assembly 2 and the cover assembly 1 together form a receiving space S. Therefore, the liquid outlet 3 can be optionally opened on the shell assembly 2 or on the cover assembly 1, thereby realizing the function of exporting the liquid matrix through the liquid outlet 3.

[0045] For example, in this embodiment, the liquid outlet 3 is provided on the housing assembly 2.

[0046] For the cover assembly 1 mentioned above, please refer to... Figure 5The cover assembly 1 includes a first cover 11, a second cover 12, and a connector 13. One end of the connector 13 is connected to the first cover 11, and the other end of the connector 13 is connected to the second cover 12. The first cover 11 is movably connected to the housing assembly 2. The housing assembly 2 and the first cover 11 together define a receiving space S. The second cover 12 and the connector 13 are located within the receiving space S. The second cover 12 is used to cover or open the liquid outlet 3.

[0047] It is understandable that the first cover 11, the second cover 12 and the connector 13 are either detachable or integrally molded.

[0048] For example, in this embodiment, the first cover 11, the second cover 12, and the connector 13 are detachably connected. Please refer to [link to relevant documentation]. Figure 5 The cover assembly 1 includes a screw connector 14, and the other end of the connector 13 is provided with a screw hole 131. The second cover 12 is provided with a first through hole 121. The screw connector 14 passes through the first through hole 121 and is screwed into the screw hole 131. This method makes the later maintenance and replacement of the cover assembly 1 more convenient, especially for the replacement and maintenance of vulnerable parts such as the second cover 12 used to seal the liquid outlet hole 3.

[0049] Understandably, the first cover 11 and the connector 13 can also be connected in a detachable manner. The specific structure is analogous to the connection structure of the connector 13 and the second cover 12. No further examples will be given here. The detachable connection between the first cover 11 and the connector 13 makes it easier to replace such a vulnerable part as the connector 13.

[0050] In some embodiments, the reservoir 100 includes a limiting member 4, which restricts the movement of the cover assembly 1, thereby controlling the volume of the liquid matrix discharged from the reservoir 100. Specifically, the presence of the limiting member 4 limits the maximum distance the cover assembly 1 can move from a preset first position L1 to a preset second position L2. As is well known, the formula for calculating volume is: V = s * l (V represents the volume of the liquid matrix, s represents the cross-sectional area of ​​the receiving space, and l represents the movement distance of the cover assembly). Therefore, in this embodiment, the presence of the limiting member 4 constrains the maximum value that l can be selected, thereby limiting the maximum total volume V of the liquid matrix that can be discharged from the receiving space.

[0051] Understandably, the limiting member 4 can be disposed on the housing assembly 2 or the cover assembly 1. Depending on the placement of the limiting member 4, the constraint distance selection standard for the movement distance l of the cover assembly 1 also differs, while the cross-sectional area of ​​the designated receiving space S remains constant. For example, when the limiting member is disposed on the cover assembly 1, one end of the limiting member is fixed to the cover assembly 1, and the other end extends towards the receiving space S. When the cover assembly 1 moves to the preset second position L2, the other end of the limiting member 4 abuts against the inner wall of the receiving space S. Therefore, when the cover assembly 1 is in the preset first position L1, the distance l between the top of the other end of the limiting member and the top wall of the receiving space S is... max1 This represents the maximum distance that the cover assembly can move, based on which l max1 The calculated V max1 This refers to the maximum total amount of liquid matrix that needs to be discharged from the containment space S; when the limiting member 4 is disposed on the housing assembly 2, the cover assembly 1 abuts against the limiting member 4 when it moves to the preset second position L2, thereby the farthest distance l between the limiting member 4 and the cover assembly when the cover assembly 1 is in the preset first position L1 is... max2 This represents the maximum distance that the cover assembly can move, based on which l max2 The calculated V max2 This refers to the reservoir containing the maximum amount of liquid matrix that needs to be discharged from the containment space S.

[0052] It should be noted that different models of atomizers have different internal storage or absorption capacities for liquid matrix. The liquid reservoir 100 of this application achieves precise adaptation through the variable stroke design of the cover assembly 1. That is, when the liquid reservoir and the atomizer are assembled, the docking structure of the atomizer will push the cover assembly 1 to move to a termination position that matches its own capacity. This termination position is not fixed at the preset second position L2, but can be dynamically adjusted within the range of the preset first position L1 to the preset second position L2 according to the specifications of different atomizers. Specifically, atomizers with larger capacities will push the cover assembly 1 to move a longer stroke (towards or at position L2), thereby discharging more liquid matrix; while devices with smaller capacities can complete the liquid conduction by moving the cover assembly 1 to a shorter stroke, and the total volume of liquid matrix discharged to the atomizer is less than or equal to V. max2 This intelligent stroke adjustment mechanism is achieved through the structural cooperation between the limiting component 4 and the atomizer interface, which not only ensures the precise quantitative delivery of the liquid matrix, but also enables a single liquid reservoir 100 to be compatible with various models of atomizers, significantly improving the product's compatibility and ease of use.

[0053] For example, in this embodiment, the limiting member 4 is disposed on the housing assembly 2. For details, please refer to [link to relevant documentation]. Figure 3 and Figure 4The housing assembly 2 includes a partition wall 4a extending laterally into the receiving space S. The partition wall 4a divides the receiving space S into a first part S1 and a second part S2 that are longitudinally distributed and interconnected. The first part S1 and the second part S2 together constitute the aforementioned receiving space S. A first cover 11 is movably disposed in the first part S1, and a second cover 12 is located in the second part S2. The liquid outlet 3 is exposed in the second part S2, that is, the liquid outlet 3 is disposed on the wall surface of the partition wall 4a facing the second part S2. The total amount of liquid matrix contained in the first part S1 is the total amount of liquid matrix that the reservoir 100 needs to discharge when the cover assembly 1 moves from the preset first position L1 to the preset second position L2.

[0054] Understandably, the partition wall 4a is provided with a connecting hole 4a1, through which the first part S1 and the second part S2 are connected. When the cover assembly 1 moves from the preset first position L1 to the preset second position L2, the liquid matrix in the first part S1 enters the second part S2 through the connecting hole 4a1. The liquid matrix in the second part S2 is squeezed out from the liquid outlet 3, thereby realizing the flow of the liquid matrix in the receiving space S.

[0055] It should be noted that the shape of the connecting hole 4a1 is adapted to the actual shape of the shell assembly 2, as long as it can enable the liquid matrix to connect from the first part S1 to the second part S2.

[0056] In some embodiments, please refer to Figure 3 and Figure 6 The partition wall 4a is provided with a movable hole 4a2, and the connector 13 passes through the movable hole 4a2. The connector 13 can slide within the movable hole 4a2 to form a sliding support structure for the cover assembly 1 to move between a preset first position L1 and a preset second position L2.

[0057] In some embodiments, please refer to Figure 4 and Figure 7 The first cover 11 is provided with a sliding hole 111 communicating with the outside. The housing assembly 2 also includes a conduit 4a3 extending from the partition wall 4a toward the first cover 11 and passing through the sliding hole 111. The liquid outlet 3 is defined by the conduit 4a3. Specifically, the liquid outlet is formed by the channel inside the conduit 4a3, which communicates with the second part S2. A portion of the conduit 4a3 protrudes from the first cover 11 so that when the atomizer and the liquid reservoir 100 are assembled, the portion of the conduit 4a3 protruding from the first cover 11 extends into the atomizer, thereby guiding the assembly of the atomizer and the liquid reservoir 100 and improving the accuracy of liquid matrix introduction into the atomizer. Furthermore, in some embodiments, please refer to Figure 3 and Figure 7A limiting boss 4a4 extends from the wall surface of the partition wall 4a toward the first part S1. The limiting boss 4a4 is circumferentially disposed at the connection position between the conduit 4a3 and the partition wall 4a. The limiting boss 4a4 is annular in shape. The limiting boss 4a4 is used to abut against the first cover 11 when the cover assembly 1 moves to the preset second position L2, so as to limit the maximum stroke of the cover assembly 1 when it moves from the preset first position L1 to the preset second position L2. Specifically, the limiting boss 4a4 limits the stroke of the first cover 11 by abutting against it. The presence of the limiting boss 4a4 improves the structural strength of the partition wall 4a, so as to reduce the degree of deformation of the partition wall 4a when the first cover 11 moves to the preset second position L2.

[0058] It is understood that the shape of the limiting boss 4a4 includes, but is not limited to, a protruding structure spaced apart around the connection position between the conduit 4a3 and the partition wall 4a, or an annular shape around the connection position between the conduit 4a3 and the partition wall 4a. For example, in this embodiment, the limiting boss 4a4 is annular.

[0059] In some embodiments, please refer to Figure 1 The cover assembly 1 includes a first sealing element 15, which is sleeved on the conduit 4a3. The outer wall of the first sealing element 15 abuts against the inner wall of the sliding hole 111, so that the conduit 4a3 slides in a sealed manner within the sliding hole 111. This ensures that the conduit 4a3 and the first cover 11 maintain a sealed connection during the reciprocating motion of the cover assembly 1 from the preset first position L1 to the second preset position L2, reducing the risk of liquid matrix in the containment space S leaking out from the gap between the conduit 4a3 and the sliding hole 111.

[0060] In some embodiments, please refer to Figure 1 and Figure 7 The partition wall 4a is provided with a sealing groove 4a5, and the liquid outlet 3 extends to the bottom of the sealing groove 4a5, that is, one end of the conduit 4a3 is connected to the bottom of the sealing groove 4a5; the cover assembly 1 includes a second sealing member 16, at least a portion of the second sealing member 16 is accommodated in the sealing groove 4a5, the second sealing member 16 is provided with a second through hole 161, the second through hole 161 is connected to the liquid outlet 3, the second sealing member 16 is used to seal the gap between the second cover 12 and the partition wall 4a when the second cover 12 covers the liquid outlet 3, so that when the cover assembly 1 is in the preset first position L1, that is, when the second cover 12 is in the preset first position L1, the second cover 12 presses the second sealing member 16, thereby blocking the second through hole 161 and the liquid outlet 3, reducing the risk of liquid matrix leakage when the liquid reservoir 100 is not assembled with the atomizer.

[0061] Since the cover assembly 1 is movable relative to the housing assembly 2 between the first position L1 and the second position L2, in order to reduce leakage of the liquid matrix from the gap between the cover assembly 1 and the inner wall of the housing assembly 2 due to the compression of the cover assembly 1 and the gravity of the liquid matrix during the movement, a third seal 17 is provided between the cover assembly 1 and the inner wall of the housing assembly 2 in some embodiments.

[0062] Specifically, the side wall of the first cover 11 is provided with a second sealing groove 112, the third sealing member 17 is received in the second sealing groove 112, and a portion of the third sealing member 17 protrudes from the second sealing groove 112. The portion of the third sealing member 17 protruding from the second sealing groove 112 abuts against the inner peripheral wall of the second part S2, so that when the first cover 11 slides in the first part S1, a sealing connection is formed between the inner peripheral walls of the first cover 11 and the second part S2, thereby realizing the sealed sliding of the first cover 11.

[0063] Understandably, the cover assembly 1 moves from the preset first position L1 to the preset second position L2 by pushing the cover assembly 1 when the external atomizer is installed in the liquid reservoir 100. When it is necessary to replenish the liquid matrix, the cover assembly 1 needs to be moved from the preset second position L2 to the preset first position L1. The methods to achieve this include, but are not limited to: relying on the liquid pressure during liquid injection to push the cover assembly 1 to move, manually pushing it, or setting an elastic element to rely on the elastic potential energy accumulated by the elastic element when the cover assembly 1 moves from the preset first position L1 to the preset second position L2 to continue pushing it.

[0064] For example, in this embodiment, the movement of the cover assembly 1 from a preset second position L2 to a preset first position L1 is achieved by setting an elastic element. The reservoir 100 also includes an elastic element 5, which is used to drive the cover assembly 1 from the preset second position L2 back to the preset first position L1.

[0065] For details, please refer to Figure 3 The elastic element 5 is preferably a compression spring 5a, which is compressed between the first cover 11 and the partition wall 4a. Specifically, the compression spring 5a is sleeved on the connector 13 to improve the space utilization rate in the first part S1 and enhance the integration of the reservoir 100. One end of the compression spring 5a abuts against the wall of the first cover 11 facing the first part S1, and the other end of the compression spring 5a abuts against the wall of the partition wall 4a facing the first part S1. The compression spring 5a is in a pre-compressed state when assembled between the first cover 11 and the partition wall 4a, so that the compression spring 5a can generate an elastic abutment force to push the first cover 11 away from the partition wall 4a, thereby keeping the first cover 11 in a preset first position L1 without being subjected to external force.

[0066] Furthermore, in some embodiments, please refer to Figure 3 The first cover 11 has an abutment groove 113 on the wall facing the first part S1. One end of the compression spring 5a is received in the abutment groove 113 and abuts against the bottom of the groove 113, reducing the shaking of the compression spring 5a when it undergoes elastic deformation under force, and improving the stability of the cover assembly 1 when it moves between the preset first position L1 and the preset second position L2.

[0067] Understandably, in some embodiments, the wall surface of the partition wall 4a surrounding the first part S1 may also be provided with a second abutment groove 113, and the other end of the compression spring 5a is received in the second abutment groove 113 and abuts against the bottom of the second abutment groove 113, so as to further improve the stability of the compression spring 5a when elastic deformation occurs and reduce the shaking of the compression spring 5a.

[0068] For housing component 2 mentioned above, please refer to... Figure 6 and Figure 7 The housing assembly 2 includes an upper shell 21 and a bottom shell 22. A partition wall 4a is disposed on the bottom shell 22. The cover assembly 1 is assembled on the bottom shell 22. The upper shell 21 and the partition wall 4a define a second part S2. The bottom shell 22 and the cover assembly 1 define a second part S2. The upper shell 21 and the bottom shell 22 are detachably assembled together and are sealed together to prevent liquid matrix from flowing out from the gap at the connection position of the upper shell 21 and the bottom shell 22.

[0069] Specifically, the bottom shell 22 includes a base 221 and a connector 222. The base 221 is fixed to the wall surface of the partition wall 4a facing the first part S1, and the connector 222 is fixed to the wall surface of the partition wall 4a facing the second part S2. The peripheral extension of the connector 222 at the connection point with the partition wall 4a forms an abutment portion 223. When the upper shell 21 and the bottom shell 22 are assembled, the end of the upper shell 21 abuts against the abutment portion 223, the connector 222 is accommodated in the second part S2, and the connector 222 abuts against the inner peripheral wall of the upper shell 21. The detachable arrangement of the upper shell 21 and the lower shell facilitates the assembly of the liquid reservoir 100, improves the processing efficiency of the liquid reservoir 100, and is beneficial for mass production.

[0070] Furthermore, the housing assembly 2 includes a fourth seal 18, which is fitted onto the end of the insertion portion 222 away from the partition wall 4a, and is held by the insertion portion 222 and the inner peripheral wall of the upper shell 21 to seal the gap between the insertion portion 222 and the inner peripheral wall of the upper shell 21.

[0071] It is understood that the optional materials for the first seal 15, the second seal 16, the third seal 17, and the fourth seal 18 described above include, but are not limited to, silicone, rubber, and plastic. For example, in this embodiment, the first seal 15, the second seal 16, the third seal 17, and the fourth seal 18 are all preferably made of silicone.

[0072] In this embodiment, relying on the cover assembly 1 movably disposed on the housing assembly 2, when the cover assembly 1 moves between the preset first position L1 and the preset second position L2, the cover assembly 1 compresses the volume of the receiving space S, and squeezes out the liquid matrix stored in the receiving space S through the liquid outlet 3. This allows the atomizing component assembled with the liquid reservoir 100 to store a certain amount of liquid matrix, so that the user can immediately start inhaling after completing the assembly of the liquid reservoir 100 and the atomizing component, without having to wait for the liquid matrix to slowly flow into the atomizer, thus improving the user experience.

[0073] This application provides embodiments of electronic atomization devices; please refer to [link / reference]. Figure 8 The electronic atomizing device includes an atomizer 200 and the aforementioned liquid reservoir 100. The liquid reservoir 100 can be assembled with the atomizer 200. For the structure and function of the liquid reservoir 100, please refer to the above embodiments, which will not be repeated here.

[0074] The atomizer 200 is provided with a receiving chamber (not shown) for housing the liquid reservoir 100. When the liquid reservoir 100 is housed in the receiving chamber, the atomizer 200 and the liquid reservoir 100 are connected to each other. The connection can be either detachable or non-detachable. When it is detachable, the liquid reservoir 100 can be replaced so that a new liquid reservoir 100 can be replaced after the liquid matrix in the liquid reservoir 100 is consumed. When it is non-detachable, the entire electronic atomizing device needs to be discarded after the liquid matrix in the liquid reservoir 100 is consumed.

[0075] The atomizer 200 also includes a liquid guiding channel (not shown) and an atomizing component (not shown). The liquid guiding channel connects the liquid outlet 3 of the reservoir 100 and the atomizing component. When the reservoir 100 and the atomizer 200 are connected, the pushing part in the atomizer 200 pushes the cover assembly 1 from a first position to a second position, thereby squeezing out the liquid matrix in the reservoir 100. The squeezed-out liquid matrix further enters the liquid guiding channel and is then transferred to the atomizing component. The atomizing component atomizes the liquid matrix to generate an aerosol that can be inhaled by the user. The atomizer 200 also includes a mouthpiece (not shown), which has an air outlet for the aerosol to escape. The air outlet is fluidly connected to the atomizing component, so that the user can inhale the aerosol when inhaling through the mouthpiece.

[0076] In some embodiments, the atomizing component may include a heating element, which heats the liquid matrix to atomize it and generate an aerosol; or, in some embodiments, the atomizing component may also include an atomizing plate, which vibrates the liquid matrix at high frequency to atomize it and generate an aerosol. This application does not limit the type of atomizing component, as long as the atomizing component can atomize the liquid matrix into an aerosol.

[0077] When the reservoir 100 is assembled with the atomizer 200, the atomizer 200 can drive the cover assembly 1 to move to the second position L2, thereby promoting the flow of a portion of the liquid matrix in the receiving space S into the atomizer 200 through the liquid outlet 3.

[0078] It should be noted that the atomizer 200 of the electronic atomizing device can have different specifications, which results in different positions of the atomizer 200 pushing the cap assembly 1. Specifically, as shown below... Figure 8 As shown, attached Figure 8 The diagram shows the positions of the cover assembly 1 after two different sizes of atomizers 200 are assembled with the liquid reservoir. The different positions of the cover assembly 1 indicate that the preset second position of the cover assembly 1 is not fixed and will be adaptively adjusted according to different atomizers 200.

[0079] It should be noted that while preferred embodiments of this application are provided in the specification and accompanying drawings, this application can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are not intended to impose additional limitations on the content of this application; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this application. Furthermore, the above-described technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this application's specification. Moreover, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
