[0038] The present application will be further described in detail by specific embodiments in conjunction with the accompanying drawings. In different embodiments, similar elements are associated with similar element reference numbers. 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 can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail according to the description in the specification and general technical knowledge in the art.

[0039] In addition, features described in the specification, operations or characteristics can be combined in any appropriate manner to form various embodiments. Meanwhile, the steps or actions in the method description can also be sequentially changed or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the 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.

[0040] The serial numbers of the components in the specification, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. The "connection" and "coupling" in the present application include direct and indirect connections (couplings) unless otherwise specified.

[0041] When studying the atomization mechanism of the electronic atomization device, the working state of the inside of the atomization core cannot be directly observed from the outside, which increases the difficulty of studying the atomization mechanism. In the present application, an observation port is provided on the liquid storage member, and a notch corresponding to the observation port is provided on the atomization core, so that the working state of the inside of the atomization core can be directly observed, thereby reducing the difficulty of studying the atomization mechanism.

[0042] Please refer to Figures 1 to 8 In an embodiment, an atomization simulation device is provided, which mainly comprises an atomization core 5 and a liquid storage member 1. The liquid storage member 1 is provided with a liquid storage cavity 103 for storing an atomization substrate. The liquid storage member 1 is provided with a mounting portion 101, and the atomization core 5 is fixed to the mounting portion 101. The liquid storage cavity 103 and the atomization core 5 are connected through a liquid path to provide the atomization substrate to the atomization core 5.

[0043] It can be understood that the atomization substrate can not be provided in the liquid storage cavity 103, and the atomization substrate can be added to the liquid storage cavity 103 for atomization during use. In some application scenarios, the atomization substrate can also be directly provided in the liquid storage cavity 103, and the atomization substrate can be directly used without adding the atomization substrate to the liquid storage cavity 103 during use. The atomization substrate in the present embodiment can be a medicinal liquid, tobacco tar or other liquid substrate that can be atomized. The material of the liquid storage member 1 is not limited in the present embodiment, which can be metal, plastic or other materials.

[0044] In the present embodiment, as Figure 1 , Figure 2 At least part of the atomization core 5 is provided with a notch 505 that exposes the inside of the atomization core 5, and the liquid storage member 1 is provided with an observation port 102 corresponding to the notch 505 for observing the working state of the inside of the atomization core 5 during research. When the atomization core 5 is mounted on the mounting portion 101 of the liquid storage member 1, the observation port 102 corresponds to the notch 505, so that the inside of the atomization core 5 can be directly observed through the observation port 102 and the notch 505, the observation of the working state of the atomization core during the research is convenient, and the difficulty of the research is reduced.

[0045] In one embodiment, the atomizing core 5 has an open or semi-open structure, with a notch 505 extending from the outer wall of the atomizing core 5 into its interior, and the notch 505 extending along the length of the atomizing core 5. In this embodiment, at least a portion of the atomizing core 5 is at least a portion along its length, meaning the notch 505 may not penetrate the atomizing core 5 vertically, or it may penetrate the atomizing core 5 vertically. In this embodiment, when the atomizing core 5 has an open structure, the notch 505 penetrates the atomizing core 5 vertically; when the atomizing core 5 has a semi-open structure, the notch 505 does not completely penetrate the atomizing core 5 vertically. In one embodiment, when it does not completely penetrate vertically, the length of the notch 505 extending along the length of the atomizing core 5 is less than the length of the atomizing core 5 but greater than half the length of the atomizing core 5, so that the interior of the atomizing core 5 is fully exposed. When the notch is not completely through the top and bottom, the notch 505 can have a gap between it and the top of the atomizing core 5, or a gap between the notch 505 and the bottom of the atomizing core 5, or a gap between the notch 505 and both the bottom and top of the atomizing core 5, as long as the notch 505 corresponds to the observation port 102. In this embodiment, both open-type and semi-open-type atomizing core 5 can expose the interior of the atomizing core 5, which facilitates research.

[0046] One embodiment, such as Figures 3-5 The mounting part 101 is a mounting groove provided at one end of the liquid storage component 1. The shape of the mounting groove is adapted to the shape of the atomizing core 5. The atomizing core 5 is fixed in the mounting groove. The mounting groove has a liquid outlet hole 105 communicating with the liquid storage chamber 103. The observation port 102 is provided on the side wall of the liquid storage component 1 and corresponds to the position of the mounting groove. The atomizing core 5 can be exposed from the side wall of the liquid storage component 1 through the observation port 102. The mounting part has a groove-shaped structure, which allows the atomizing core 5 to be embedded in the liquid storage component 1, which facilitates the liquid storage component 1 to provide atomizing matrix to the atomizing core 5. In this embodiment, the depth of the mounting groove can be greater than or equal to the height of the atomizing core 5, that is, the atomizing core 5 does not protrude from the end of the liquid storage component 1; in some application scenarios, the depth of the mounting groove can also be less than the height of the atomizing core 5, that is, the atomizing core 5 can also partially protrude from the bottom of the liquid storage component 1.

[0047] The mounting groove in the embodiment can be integrally formed with the liquid storage member 1. For example, when the liquid storage member 1 is made of metal, the mounting groove can be integrally formed when the liquid storage member 1 is cast. Or when the liquid storage member 1 is made of plastic, the mounting groove can be integrally formed when the liquid storage member 1 is injection molded. But it is not limited to this. The liquid storage member 1 and the mounting groove on the liquid storage member 1 can also be made by other ways. In the embodiment, the groove wall profile of the mounting groove is adapted to the outer profile of the atomization core 5. That is, when the outer profile of the atomization core 5 is cylindrical, the groove wall profile of the mounting groove can also be cylindrical. When they are adapted, the positioning is better. In some application scenarios, the groove wall profile of the mounting groove can also not be adapted to the outer profile of the atomization core 5. In the embodiment, the mounting portion 101 can be located at the center of the end of the liquid storage member 1. In some application scenarios, the mounting portion 101 can also be arranged away from the center of the end of the liquid storage member 1. The mounting portion 101 in the embodiment is not limited to the structure described above. It can also be other structures that are convenient for mounting the atomization core 5. For example, a clamping portion is arranged on the liquid storage member 1. The atomization core 5 is clamped and fixed by the clamping portion. The observation port 102 corresponds to the clamping portion or is directly arranged on the clamping portion.

[0048] An embodiment is as follows, Figure 2 The atomization core 5 includes an atomization tube 503, a liquid guide 502 and a heating element 501. The heating element 501 is arranged in the atomization tube 503. The liquid guide 502 is located between the atomization tube 503 and the heating element 501. The outer shape of the atomization tube 503 is adapted to the shape of the mounting groove. The outer side wall of the atomization tube 503 is tightly fitted with the groove wall of the mounting groove, so as to fix the atomization core 5 in the mounting groove.

[0049] It can be understood that the atomization core 5 in the embodiment can atomize the atomization substrate to form an aerosol. The heating element 501 is used for heating the atomization substrate. The gap 505 is arranged to expose the heating element 501 inside the atomization core 5 for observation. In the embodiment, the liquid guide 502 encloses the heating element 501. In some application scenarios, the liquid guide 502 can be liquid storage cotton. The heating element 501 is wrapped by the liquid storage cotton, so as to sufficiently provide the atomization substrate to the heating element 501. In the embodiment, the atomization tube 503 encloses the liquid guide 502 and the heating element 501. The atomization tube 503 can also be provided with a gap. The gap of the atomization tube 503, the gap of the liquid guide 502 and the gap of the heating element 501 correspond to each other, so as to form the gap 505 arranged on the atomization core 5. In the embodiment, the gap 505 can be formed by mechanical cutting. The atomization tube 503 can be provided with a through hole 504. The through hole 504 on the atomization tube 503 corresponds to the liquid outlet hole 105 on the liquid storage member 1, so as to realize the communication of the liquid path between the liquid storage cavity 103 and the atomization core 5. The atomization substrate in the liquid storage member 1 can flow into the liquid guide 502. In the embodiment, the working state of the atomization core 5 can include but is not limited to the atomization state and the boiling state of the substrate.

[0050] An embodiment is as follows, Figure 1The atomizing core 5 is arranged in the mounting groove along the axial direction of the liquid storage member 1. The side wall of the liquid storage member 1 is provided with a groove which penetrates through the opposite ends of the liquid storage member 1 along the axial direction of the liquid storage member 1 to form an observation port 102, and the groove is communicated with the mounting groove. The groove is simple to process and has a lower manufacturing cost. The groove can be integrally formed with the liquid storage member 1. For example, when the liquid storage member 1 is made of metal, the groove and the mounting groove can be integrally formed when the liquid storage member 1 is cast. Or when the liquid storage member 1 is made of plastic, the groove and the mounting groove can be integrally formed when the liquid storage member 1 is injection molded. However, the groove can also be formed by other methods. In some application scenarios, the observation port 102 can also be a transparent part provided on the side wall of the liquid storage member 1. The transparent part can be made of glass or transparent plastic. However, the observation port 102 can also be other structures which can expose the atomizing core 5. In one embodiment, when the groove penetrates through the bottom of the liquid storage member 1 to the top of the liquid storage member 1, that is, the height of the groove is equal to the height of the liquid storage member 1, the dead angle of the liquid storage member 1 is small, and the cleaning of the liquid storage member 1 is facilitated. In some embodiments, the height of the groove can also be greater than or equal to the height of the mounting groove and less than the height of the liquid storage member 1. The specific height can be selected according to actual needs.

[0051] In one embodiment, Figure 6 When the height of the groove is equal to the height of the liquid storage member 1, the liquid storage member 1 can include a top shell wall 106, a bottom shell wall, a side shell wall, and a groove-shaped shell wall 108 forming the mounting groove. The top end of the side shell wall is connected to the top shell wall 106, and the bottom end of the side shell wall is connected to the bottom shell wall. The side shell wall includes an arc-shaped shell wall 109 and two plane shell walls 107. The two plane shell walls 107 are respectively connected to the two ends of the arc-shaped shell wall 109, and the two plane shell walls 107 are connected on the axis of the liquid storage member 1 to form the groove. The two plane shell walls 107 are connected to the bottom shell wall at the position of the communication port 110. The edge of the groove-shaped shell wall 108 is connected to the edge of the communication port 110 to form the mounting groove communicated with the groove. It can be understood that the two plane shell walls 107 are connected on the axis of the liquid storage member 1, that is, the intersection line of the two plane shell walls 107 coincides with the axis of the liquid storage member 1 to form a groove with a fan-shaped cross section. The arc-shaped shell wall 109 in this embodiment is in the shape of a circular arc and can be an arc greater than a semicircle. The communication port 110 in this embodiment cuts the two plane shell walls 107 and the bottom shell wall. The edge of the groove-shaped shell wall 108 is connected to the edge of the communication port 110, that is, the edge of the groove-shaped shell wall 108 is respectively sutured to the edges of the two plane shell walls 107 and the bottom shell wall cut by the communication port 110. After suturing, the mounting groove communicated with the groove is formed. In some embodiments, the liquid storage member 1 can also have other structures. For example, the side shell wall can be surrounded by a plurality of plane shell walls connected in sequence, in which the intersection line of two plane shell walls coincides with the axis of the liquid storage member 1 to form the groove. The groove in this embodiment can also have other structures other than the above structures. For example, the groove can also be a slot with a rectangular or trapezoidal cross section.

[0052] An embodiment, as Figure 4 The liquid storage member 1 is also provided with at least one liquid injection hole at one end thereof away from the mounting portion 101, which is in communication with the liquid storage cavity 103. The liquid storage member 1 further comprises a liquid injection plug 9, which seals the liquid injection hole. The liquid injection hole facilitates the addition of the atomization substrate in the liquid storage member 1. The shape of the liquid injection hole is not specifically limited in the present embodiment, and can be circular or square, for example. In the present embodiment, one or two liquid injection holes can be provided. When two liquid injection holes are provided, the sealing liquid injection plug 9 can be provided in an integral structure. The integral liquid injection plug 9 has two sealing portions corresponding to the two liquid injection holes, respectively. The integral liquid injection plug 9 facilitates the opening of the liquid injection hole during liquid injection, and is less likely to be lost.

[0053] An embodiment, as Figure 7 , Figure 8 In order to make the working parameters of the atomization core 5 more consistent with the actual situation, the atomization simulation device further comprises a pressure control assembly, which is in communication with the liquid storage cavity 103 and is used to adjust the pressure inside the liquid storage cavity 103. In the actual working environment of the atomization core 5, there are various pressure environments. The pressure control assembly is used to adjust and control the pressure inside the liquid storage cavity 103, so as to simulate the working state of the atomization core 5 under various pressure environments. As a result, the simulated working parameters are more close to the actual working parameters of the atomization core 5, and the effectiveness and reliability of the research results are improved. In some application scenarios, only the working state of the atomization core 5 in the atmospheric environment needs to be simulated. In this case, the pressure control assembly can also be omitted.

[0054] An embodiment, the pressure control assembly comprises a pressure regulating tube 3, a first pressure control portion 7 and a second pressure control portion 8. The pressure regulating tube 3 is provided in a U shape, and is provided with a pressure control liquid 6. The first pressure control portion 7 and the second pressure control portion 8 are respectively provided at two ends of the pressure regulating tube 3. The first pressure control portion 7 is provided with a first pressure regulating cavity 701, and the second pressure control portion 8 is provided with a second pressure regulating cavity 801. One end of the first pressure regulating cavity 701 is in communication with the liquid storage cavity 103, and the other end of the first pressure regulating cavity 701 is in communication with one end of the pressure regulating tube 3. One end of the second pressure regulating cavity 801 is in communication with the other end of the pressure regulating tube 3, and the other end of the second pressure regulating cavity 801 is in communication with an external air pump. The second pressure regulating cavity 801 adjusts the internal pressure through the air pump, so as to change the liquid level of the pressure control liquid 6 to control the pressure in the first pressure regulating cavity 701, so that the first pressure regulating cavity 701 is used to adjust the pressure in the liquid storage cavity 103.

[0055] It can be understood that the pressure regulating tube in the embodiment is arranged in a U shape, so that the control pressure liquid 6 has two liquid levels respectively at two ends of the pressure regulating tube 3. The first control pressure part 7 and the second control pressure part 8 in the embodiment are respectively located at two ends of the pressure regulating tube 3. The first control pressure part 7 and the second control pressure part 8 can also be tubular structures, and the first control pressure part 7 and the second control pressure part 8 can be connected at two ends of the pressure regulating tube 3 by a connecting mode, or can be integrally arranged with the pressure regulating tube 3. The first control pressure part 7 and the second control pressure part 8 in the embodiment are hollow to form a first pressure regulating cavity 701 and a second pressure regulating cavity 801. The second pressure regulating cavity 801 communicates with an external air pump. The air pump performs air extraction or air charging on the second pressure regulating cavity 801 to control the liquid level change at two ends of the control pressure liquid 6. When the second pressure regulating cavity 801 is subjected to air extraction, the liquid level of the control pressure liquid 6 at one side of the first pressure regulating cavity 701 moves downward, so that the pressure in the first pressure regulating cavity 701 can be reduced. When the second pressure regulating cavity 801 is subjected to air charging, the liquid level of the control pressure liquid 6 at one side of the first pressure regulating cavity 701 moves upward, so that the pressure in the first pressure regulating cavity 701 can be increased. When the liquid level of the control pressure liquid 6 at one side of the first pressure regulating cavity 701 remains unchanged, the pressure in the first pressure regulating cavity 701 remains constant. The first pressure regulating cavity 701 in the embodiment communicates with the liquid storage cavity 103, so that the working parameters of the atomizing core 5 in different pressure environments can be obtained. The mode of adjusting the pressure in the first pressure regulating cavity 701 by the liquid level change of the control pressure liquid 6 is simple, the manufacturing cost is low, and the pressure in the first pressure regulating cavity 701 can be stably maintained.

[0056] In some embodiments, the second pressure regulating chamber 801 can also be an open chamber, and the first pressure regulating chamber 701 is in a sealed state, so that the pressure regulating liquid 6 can be supplemented or sucked through the second pressure regulating chamber 801 into the pressure regulating tube 3 to control the change of the liquid level of the pressure regulating liquid 6. For example, when the pressure regulating liquid 6 is supplemented into the pressure regulating tube 3 through the opening of the second pressure regulating chamber 801, the liquid level of the pressure regulating liquid 6 on one side of the first pressure regulating chamber 701 moves upward, increasing the pressure in the first pressure regulating chamber 701; when part of the pressure regulating liquid 6 in the pressure regulating tube 3 is sucked through the opening of the second pressure regulating chamber 801, the liquid level of the pressure regulating liquid 6 on one side of the first pressure regulating chamber 701 moves downward, reducing the pressure in the first pressure regulating chamber 701. The specific way of regulating the change of the liquid level of the pressure regulating liquid 6 by the second pressure regulating chamber 801 in this embodiment is not limited to the above-mentioned embodiments, and any way that can regulate the change of the liquid level of the pressure regulating liquid 6 is acceptable. The pressure regulating assembly in this embodiment is not limited to including the above-mentioned structures or components, and can also include other structures or components that facilitate pressure regulation and control, such as a pressure sensor that is connected to the first pressure regulating chamber 701 and used to detect the pressure in the first pressure regulating chamber 701, so that the pressure in the first pressure regulating chamber 701 can be visualized, which is more conducive to research. Alternatively, a sealing ring that increases the sealing performance can also be included. When the pressure sensor is provided, the pressure sensor can be connected to one side of the first pressure regulating chamber 701 through a hole provided in the side wall of the first pressure regulating part 7, or the pressure sensor can be directly provided at the port of the first pressure regulating chamber 701 that is sealed by the sealing ring on the upper end of the first pressure regulating chamber 701, as long as the pressure sensor can detect the pressure in the first pressure regulating chamber 701.

[0057] In one embodiment, the atomization simulation device further comprises a liquid supply member 2, one end of the liquid supply member 2 is in communication with the liquid storage member 1, and the other end of the liquid supply member 2 is in communication with the first pressure regulating chamber 701, the liquid supply member 2 is used to supplement the atomization substrate into the liquid storage chamber 103, and is used to measure the consumption of the atomization substrate when the atomization core 5 is working. In use, a certain amount of atomization substrate can be injected into the liquid supply member 2, and when part of the atomization substrate is atomized by the atomization core 5, the atomization substrate in the liquid supply member 2 will be supplemented into the liquid storage chamber 103 accordingly, and the liquid level of the liquid supply member 2 will move to one side of the liquid storage member 1, and the consumption of the atomization substrate can be measured and calculated through the change of the liquid level. In this embodiment, in order to ensure that the atomization substrate can be well supplemented into the liquid storage chamber 103 by the liquid supply member 2, the liquid storage chamber 103 can be filled with atomization substrate in use, and when part of the atomization substrate is atomized by the atomization core 5, the atomization substrate in the liquid supply member 2 will be supplemented into the liquid storage chamber 103 accordingly. The pressure environment in the supplementing process is controlled by the pressure regulating assembly, and the pressure in the liquid supply member 2 is more easily controlled, and the effect of pressure control is better.

[0058] In one embodiment, the liquid supply 2 is a capillary tube, the side wall of the liquid storage 1 is provided with a first connecting hole 104, the first pressure control part 7 is provided with a second connecting hole, one end of the capillary tube is inserted into the first connecting hole 104, and the other end of the capillary tube away from the liquid storage 1 is inserted into the second connecting hole. The outer wall of the capillary tube is provided with a scale for reading the consumption of the atomized substrate when the atomizing core 5 is working. In this embodiment, the capillary tube is a very thin tube with a certain capillary effect.

In one embodiment, the capillary tube can be a thin tube with an inner diameter of 1 mm or less. In some application scenarios, the inner diameter of the capillary tube can also be greater than 1 mm, but the inner diameter should not be too large.

In this embodiment, one end of the capillary tube is inserted into the first connecting hole 104 to connect the capillary tube with the liquid storage cavity 103, and the other end of the capillary tube away from the liquid storage 1 is inserted into the second connecting hole to connect the capillary tube with the first pressure regulating cavity 701.

In this embodiment, the position of the second connecting hole should always be higher than the liquid level of the pressure control liquid 6 to prevent the pressure control liquid 6 from entering the capillary tube through the second connecting hole and affecting normal use.

When the liquid supply member 2 is arranged, the consumption of the atomization matrix can also be read and calculated through the change of the liquid level in the liquid supply member 2, so that the research data is more comprehensive.
