[0027] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0028] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0029] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0030] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0031] The electronic atomization device in the traditional technology usually includes a cigarette cartridge and a cigarette rod. The capacity of the cigarette cartridge is small, and the cigarette cartridge needs to be replaced as a whole when replenishing the atomization matrix, which is costly. In order to solve the above problems, a liquid storage device for replenishing the atomization matrix has been developed. By connecting the liquid storage device to the electronic atomization device, the atomization matrix can be replenished. In the current electronic atomization device, in order to facilitate the additional liquid storage device to be easily connected to the electronic atomization device, an oil guide tube is usually set in the electronic atomization device. After the oil guide tube is inserted into the liquid storage device, the atomization matrix in the liquid storage device can be introduced into the electronic atomization device, so that the atomization matrix in the liquid storage device can be connected to the overall liquid inlet channel of the electronic atomization device for replenishment. However, the additional liquid storage device is usually arranged with the outlet facing upward, and the oil outlet direction is from bottom to top. Gravity will limit the output of the atomization matrix and affect the oil replenishment efficiency.

[0032] In order to solve the above problems, the present application proposes an electronic atomization device, which includes a shell and a liquid guide tube. The shell is provided with a liquid storage cavity, and the liquid guide tube is used to extend into the liquid storage device to absorb and conduct the atomized matrix. Among them, the liquid guide tube includes two sections with different diameters, and the section with a smaller diameter is used to insert into the liquid storage device to improve the transmission efficiency of the atomized matrix. The section with a larger diameter is used to connect the liquid storage cavity to improve the efficiency of inputting the atomized matrix into the liquid storage cavity. In this way, the oil replenishment efficiency of the electronic atomization device can be comprehensively improved. It should be noted that the Young-Laplace formula: In the formula, P represents the pressure of the concave liquid surface due to capillary action caused by surface tension or wall tension, γ is the surface tension coefficient of the atomized matrix, θ is the angle between the liquid surface and the tube wall, and D is the tube diameter. In other words, according to the Young-Laplace formula, when other conditions are constant, the pressure effect of the liquid guide tube on the atomized matrix is ​​inversely proportional to the inner diameter D of the liquid guide tube. Therefore, the pressure difference is greater when the tube diameter is smaller, which can improve the oil replenishment efficiency. The electronic atomization device and the aerosol generating device including the electronic atomization device are described in detail below in conjunction with the specific implementation methods and the drawings in the specification.

[0033] See also Figure 1 and Figure 2 The aerosol generating device 10 provided in one embodiment of the present application includes an electronic atomization device 100 and a liquid storage device 200. The liquid storage device 200 can be installed in the electronic atomization device 100 to provide an atomization matrix for the electronic atomization device 100. The liquid storage device 200 is generally a hollow container. Compared with the conventional technology in which the liquid storage device and the atomization component are integrated to form a cigarette cartridge, the liquid storage device 200 has a simple structure, is easy to design with a larger capacity, and has a lower replacement cost.

[0034] See also Figure 2 and Figure 4 In one embodiment, the electronic atomization device 100 includes a housing 110 and a liquid conduit 120, and the liquid conduit 120 is disposed in the housing 110. The liquid conduit 120 includes a first pipe section 121 and a second pipe section 122 that are interconnected, the first pipe section 121 is connected to the liquid storage chamber 112, and the inlet end 125 of the second pipe section 122 is configured to be located at the installation position 111 for connecting to the liquid storage device 200. Figure 7 , the inner diameter d2 of the second pipe section is smaller than the inner diameter d1 of the first pipe section.

[0035] In the above-mentioned electronic atomization device 100, the liquid conduit 120 can extend inwardly at the installation position 111 to connect with the liquid storage device 200, and the liquid storage device 200 can be refilled with oil through the liquid conduit 120. In addition, the liquid conduit 120 includes a first pipe section 121 and a second pipe section 122 with different inner diameters. As mentioned above, under the same other conditions, the smaller the inner diameter, the stronger the capillary effect of adsorbing and conducting the atomized matrix. Therefore, providing the first pipe section 121 with a smaller inner diameter to connect with the liquid storage device 200 can improve the conduction efficiency of the atomized matrix in the liquid storage device 200 in the liquid conduit 120.

[0036] Furthermore, a liquid guiding member (not shown) may be provided in the liquid guiding tube 120 and / or the liquid storage chamber 112 to further improve the liquid guiding efficiency of the atomized matrix in the liquid storage device 200 in the liquid tube 120 and improve the stability of the liquid guiding.

[0037] Furthermore, by providing a second pipe section 122 with a larger inner diameter, the contact area between the liquid guide tube 120 and the liquid storage chamber 112 can be increased, and the efficiency of the liquid guide tube 120 in transmitting the atomized matrix to the liquid storage chamber 112 can be increased. From another perspective, when the second pipe section 122 has a larger inner diameter, if the conduction area with the liquid storage chamber 112 is set to be the same as when the inner diameter is smaller, the second pipe section 122 can have more inner walls contacting the atomized matrix in the tube, so the capillary effect can be improved and the oil replenishment efficiency can be improved. Therefore, the present application is so arranged that the efficiency of the liquid guide tube 120 absorbing and transmitting the atomized matrix from the liquid storage device 200 to the liquid storage chamber 112 can be improved, that is, the oil replenishment efficiency is comprehensively improved.

[0038] To facilitate understanding of the aerosol generating device 10 provided in the present application, the following is combined with Figure 2 and Figure 3 The connection relationship and positional relationship of the various components included in the aerosol generating device 10 provided in one embodiment of the present application are briefly described. It should be understood that the following description does not limit the aerosol generating device 10. Several modifications and improvements can be made without departing from the concept of the present application.

[0039] The aerosol generating device 10 further includes an atomizing assembly 130, which is disposed in the housing 110 and communicated with the liquid storage chamber 112. The atomizing assembly 130 is arranged eccentrically with the mounting position 111, for example, the atomizing assembly 130 and the mounting position 111 can be arranged side by side, and the atomizing assembly 130 is in lateral communication with the liquid storage chamber 112 and the liquid conduit 120 and the liquid storage device 200. The housing 110 is provided with a suction nozzle 114, and the atomizing assembly 130 can convert the atomized matrix into an aerosol and output it from the suction nozzle 114. The liquid conduit 120 is disposed in the housing 110, and when the liquid storage device 200 is mounted in the mounting position 111, the liquid conduit 120 is inserted into the liquid storage device 200 to communicate the liquid storage device 200 with the atomizing assembly 130, so that the liquid conduit 120 can obtain the atomized matrix and provide it to the atomizing assembly 130 through the liquid storage chamber 112. Thus, the aerosol generating device 10 can output aerosol to the outside. Figure 3 Winning bid number Q1.

[0040] It should be noted that, although the smaller the inner diameter of the liquid guide tube 120 is, the stronger its effect of adsorbing and conducting the atomized matrix is, the smaller the inner diameter of the liquid guide tube 120 is, the higher the oil replenishment efficiency is. The reason is that the smaller the inner diameter of the liquid guide tube 120 is, the smaller the flow rate of the atomized matrix is. Therefore, please refer to Figure 7In one embodiment, the inner diameter d2 of the second pipe segment can be set to 4.5 mm to 8.5 mm, that is, 4.5 mm≤d2≤8.5 mm. For example, the inner diameter d2 of the second pipe segment can be 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, etc., so as to take into account the effect of the second pipe segment 122 in absorbing the atomized matrix and the flow rate of the atomized matrix that the second pipe segment 122 can conduct.

[0041] It should be further explained that the larger the diameter of the first tube section 121, the better. If the diameter of the first tube section 121 is too large, the adsorption and conduction effect may be weak, and the atomized matrix may be retained in the first tube section 121 and cannot enter the liquid storage chamber 112. Therefore, please continue to refer to Figure 7 In one embodiment, the ratio of the inner diameter d1 of the first tube segment to the inner diameter d2 of the second tube segment can be set to 1.05d2≤d1≤1.25d2, so as to take into account the adsorption and conduction effect of the first tube segment 121 and the contact area between the first tube segment 121 and the liquid storage chamber 112. In other words, the inner diameter d1 of the first tube segment can be between 4.7mm and 10.7mm, that is, 4.7mm≤d1≤10.5mm. For example, the inner diameter d1 of the first tube segment can be 4.7mm, 5.2mm, 5.7mm, 6.2mm, 6.7mm, 7.2mm, 7.7mm, 8.2mm, 8.7mm, 9.2mm, 9.7mm, 10.2mm, 10.7mm, etc.

[0042] Please continue reading Figure 5 In one embodiment, the tube wall of the first tube section 121 is provided with a liquid hole 124, that is, the liquid hole 124 is provided on the circumference of the first tube section 121, and the liquid hole 124 is connected to the liquid storage chamber 112. Since the atomizing assembly 130 is eccentrically arranged with the mounting position 111, the liquid hole 124 provided on the tube wall of the first tube section 121 can conveniently transfer the atomized substrate to the side. Moreover, compared with the bent liquid guide tube 120, directly providing the liquid hole 124 on the circumferential wall of the liquid guide tube 120 can simplify the structure and facilitate the delivery of the atomized substrate.

[0043] The eccentric arrangement of the atomizing assembly 130 does not mean that the cross section of the liquid storage chamber 112 is circular. In one embodiment, Figure 1 and Figure 2 The cross-sectional profile of the liquid storage chamber 112 is a composite figure composed of a rectangular profile and a semicircular profile, and the atomization assembly 130 is not located at the center of the composite figure.

[0044] It is understood that if the specific position of the center of the graphic cannot be determined, the atomizing assembly 130 may be disposed in a position not located in the liquid storage chamber 112. Figure 2 The center of the horizontal direction (i.e. width direction) shown.

[0045] See also Figure 8 In one embodiment, the liquid passage hole 124 includes an arc wall 126, which is located on a side of the liquid passage hole 124 close to the second pipe segment 122 and is concave toward the side close to the second pipe segment 122. Therefore, in the process of transporting the atomized matrix from the second pipe segment 122 to the first pipe segment 121, the atomized matrix will first contact the concave portion of the arc wall 126, and gradually flow into the liquid passage hole 124 under the guidance of the arc wall 126, and flow out of the liquid passage hole 124. As a result, the arc wall 126 can guide the atomized matrix to flow out of the liquid passage hole 124, thereby improving the oil passing efficiency of the atomized matrix. In addition, the arc wall 126 does not have a sharp corner, thereby reducing the problem of atomized matrix waste caused by the atomized matrix residing at the sharp corner based on capillary action.

[0046] See also Figures 5 to 7 In one embodiment, the liquid passage hole 124 includes a first hole portion 124a, a second hole portion 124b, and a third hole portion 124c that are interconnected. Along the axial direction of the liquid guide tube 120, the first hole portion 124a and the third hole portion 124c are respectively located on opposite sides of the second hole portion 124b. Further, the first hole portion 124a and the third hole portion 124c can be symmetrically arranged on opposite sides of the second hole portion 124b. Therefore, the first hole portion 124a is described below. If there is no contradiction, the third hole portion 124c is similar, so it will not be repeated.

[0047] The first hole portion 124a is located on the side of the second hole portion 124b close to the second tube segment 122, and the first hole portion 124a is in a half-moon shape that is concave along the axis O of the liquid guiding tube 120 toward the side where the second tube segment 122 is located. In this way, in the direction from the second tube segment 122 to the first tube segment 121 along the axis O of the liquid guiding tube 120 (such as Figure 5 and Figure 7 The concave portion of the first hole portion 124a can gradually guide the atomized matrix from the liquid guide tube 120 into the liquid hole 124, so as to improve the smoothness of the atomized matrix from the liquid hole 124 into the liquid storage chamber 112, thereby improving the oil replenishment efficiency. Figure 5 and Figure 8 Winning bid number Q2.

[0048] See also Figure 8 Combined with Figure 5 In one embodiment, the arc wall 126 is a concave structure of the first hole portion 124a.

[0049] The second hole portion 124b includes side hole walls 127 disposed opposite to each other, and the side hole walls 127 are connected to the two ends of the arc wall 126 respectively. Figure 5In the direction perpendicular to the axis O of the liquid guiding tube 120, the vertical distance L1 between the two side hole walls 127 is between 2.0 mm and 3.5 mm. For example, the vertical distance L1 between the two side hole walls 127 can be 2.0 mm, 2.5 mm, 3.0 mm, 3.5 mm, etc. Along the axis O of the liquid guiding tube 120, the size L2 of the liquid passage hole 124 is between 2 mm and 8 mm. For example, the size L2 of the liquid passage hole 124 can be 2.0 mm, 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm, 4.5 mm, 5.0 mm, 5.5 mm, 6.0 mm, 6.5 mm, 7.0 mm, 7.5 mm, 8.0 mm, etc. In this way, the physical wall size of the first tube section 121 and the conduction area between the first tube section 121 and the liquid storage chamber 112 can be taken into consideration.

[0050] Please continue reading Figure 8 In one embodiment, the catheter 120 further includes a transition section 123, which is connected between the first section 121 and the second section 122. The inner diameter of the transition section 123 gradually increases along the axis O of the catheter 120 from the second section 122 to the first section 121. Figure 7 That is to say, viewed along the direction O1, the transition pipe section 123 is in the shape of an outwardly expanding trumpet. Since the liquid passage hole 124 is provided on the tube wall of the first pipe section 121, that is, for the atomized matrix in the liquid guide tube 120, the connecting portion between the liquid guide tube 120 and the liquid storage chamber 112 is located in the peripheral area. Therefore, the atomized matrix can be guided to flow radially outward through the outwardly expanding transition pipe section 123 so as to smoothly flow out of the liquid passage hole 124 and improve the oil replenishment efficiency. At the same time, similar to the above, relative to the sudden change in the inner diameter between the first pipe section 121 and the second pipe section 122, a transition pipe section 123 for transition is provided between the first pipe section 121 and the second pipe section 122, which can reduce the probability of sharp corners in the liquid guide tube 120, and reduce the problem of waste of atomized matrix caused by the atomized matrix residing at the sharp corner due to capillary action.

[0051] See also Figure 8 In one embodiment, along the axis O of the liquid guide tube 120, the shortest distance S between the transition tube section 123 and the liquid passage hole 124 is less than or equal to 15% of the inner diameter d2 of the second tube section, that is, S≤0.15d2, so as to improve the smoothness of the atomized substrate flowing out of the liquid passage hole 124. Figure 8It is easy to understand that the atomized matrix in the transition pipe section 123 will have a flow direction (or at least a tendency) along the radially outer side under the guidance of the transition pipe section 123. Therefore, if the distance between the liquid hole 124 and the transition pipe section 123 is set small enough, the atomized matrix flowing along the eversion direction in the transition pipe section 123 can directly flow out of the liquid hole 124, reducing the collision with the pipe wall of the second pipe section 122, thereby improving the smoothness of the outflow of the atomized matrix and improving the oil replenishment efficiency. Furthermore, the shortest distance S between the transition pipe section 123 and the liquid hole 124 can be set to 0.65mm, 0.7mm, 0.75mm, 0.8mm, 1.0mm, 1.1mm, 1.2mm and 1.3mm, etc.

[0052] It should be further explained that the above description of the outflow of the atomized matrix is ​​only to describe the general movement trend and tendency of the atomized matrix, so as to facilitate understanding of the role of the transition pipe section 123 and the above-mentioned shortest distance S setting, and does not limit whether the atomized matrix will collide or will not collide with the tube wall of the liquid guide tube 120.

[0053] In one embodiment, the liquid storage chamber 112 may be filled with a porous member (not shown in the figure, the same below), which can store and conduct the atomized matrix. By adding a porous member in the liquid storage chamber 112, the conduction efficiency of the atomized medium in the liquid storage chamber 112 can be improved, thereby improving the oil replenishment efficiency.

[0054] In one embodiment, the liquid storage device 200 is filled with a guiding liquid (not shown, the same below), which is used to store and conduct the atomized matrix. When the guiding tube 120 extends into the liquid storage device 200, it contacts the guiding liquid and conducts fluid. The guiding liquid can improve the efficiency of conducting the atomized matrix into the guiding tube 120, thereby improving the oil replenishment efficiency on the one hand, and improving the utilization efficiency of the atomized matrix in the liquid storage device 200 on the other hand, thereby avoiding waste. Similar to the above, the guiding liquid can also be configured as a porous component. The porous component can be made of cotton material or ceramic material, etc.

[0055] The liquid storage device 200 can be installed in the electronic atomization device 100. The liquid storage device 200 is usually packaged, transported and sold as an independent product. Therefore, the opening of the liquid storage device 200 for the liquid guide tube 120 to be plugged in is usually provided with a sealing film (not shown) to seal the opening to prevent leakage during packaging and transportation. Therefore, it is usually necessary to remove the sealing film before installing the liquid storage device 200, which is complicated to operate. Based on this, in one embodiment, the liquid guide tube 120 can also be configured to be able to switch between a position extending inwardly in the mounting position 111 and a position spaced from the mounting position 111. In this way, the liquid storage device 200 can be installed in the mounting position 111 first, and then the liquid guide tube 120 can be controlled to move to puncture the sealing film and insert it into the liquid storage device 200. Furthermore, part of the structure of the liquid guide tube 120 can be exposed to the housing 110 to facilitate the control of the movement of the liquid guide tube 120 between the two positions.

[0056] Among them, Figure 2 As shown, the dotted box indicates the specific location of the installation position 111. Figure 2 In the example shown, the upper edge of the mounting position 111 is the top surface of the bottle mouth of the liquid storage device 200. In some other embodiments, a sealing film may be further provided at the bottle mouth of the liquid storage device 200, and the sealing film may be pierced by the inlet end 125 when the inlet end 125 is located at the mounting position 111. Furthermore, the upper edge of the mounting position 111 may also be configured as the position where the sealing film 22 is located, that is, when the sealing film is provided at the top surface of the bottle mouth of the liquid storage device 200, the upper edge of the mounting position 111 is also located at the top surface of the bottle mouth of the liquid storage device 200, and when the sealing film is provided at the middle of the liquid storage device 200, the upper edge of the mounting position 111 is also located at the middle of the bottle mouth of the liquid storage device 200. Other situations will not be described in detail.

[0057] Alternatively, please refer to Figure 2 In one embodiment, the electronic atomization device 100 further includes an activation button 140, which includes an operating portion 141 and a connecting tube 142, and the connecting tube 142 is disposed on the side of the operating portion 141 facing the liquid guide tube 120. The operating portion 141 is slidably matched with the housing 110 and partially exposed to the housing 110. The liquid guide tube 120 is fixedly plugged with the connecting tube 142 to move with the activation button 140. The activation button 140 is connected to the liquid guide tube 120, and the liquid guide tube 120 is configured to switch between a position extending inwardly in the mounting position 111 and a position spaced from the mounting position 111 under the drive of the activation button 140. In this way, the liquid guide tube 120 can be driven to move by interacting with the activation button 140. In addition, since the operating portion 141 is exposed to the housing 110, the operating portion 141 and the liquid guide tube 120 can be conveniently driven to move from outside the housing 110.

[0058] Furthermore, the electronic atomization device 100 may also include a sealing body 150, which may be filled at the connection between the liquid guide tube 120 and the connecting tube 142, and at the sliding fit between the operating part 141 and the shell 110 to reduce the probability of leakage of the atomized matrix.

[0059] Of course, in other embodiments, the liquid guide tube 120 may be fixedly arranged on the shell 110. In this case, when the liquid storage device 200 is installed, the opening is aligned with the liquid guide tube 120. By pressing the liquid storage device 200 toward the liquid guide tube 120, the liquid guide tube 120 can pierce the sealing film and extend into the liquid storage device 200.

[0060] Furthermore, if Fig. 9 , it is also possible to set the side of the liquid guide tube 120 close to the installation position 111 to be inclined at a preset angle α relative to the axis O of the liquid guide tube 120 to form a sharp end, so as to facilitate puncturing and penetrating the sealing film. The liquid guide tube 120 is provided with a lumen 128 and an inlet end 125 for absorbing the atomized matrix, the lumen 128 connects the inlet end 125 with the liquid hole 124, and the inlet end 125 is opened at the above-mentioned sharp end. It is easy to understand that the liquid guide tube 120 is a hollow tubular structure. When the end of the liquid guide tube 120 with the inlet end 125 is inclined as described above, a sharp angle is formed between the end wall of the liquid guide tube 120 and the circumferential wall, so that the sealing film can be punctured to extend into the liquid storage device 200. In addition, the side where the inlet end 125 is located is inclined, which is convenient for guiding the atomized matrix to flow into the liquid guide tube 120.

[0061] In one embodiment, the preset angle α may be between 30° and 60°, that is, 30°≤α≤60°. The specific value of the preset angle α may be selected according to actual design requirements and is not limited here.

[0062] See also Fig. 9 In one embodiment, there may be a plurality of liquid-passing holes 124, which are evenly spaced along the circumferential direction of the second pipe section 122 to improve the oil-passing efficiency of the atomized substrate. For example, there may be two liquid-passing holes 124, which are disposed in opposite directions in the second pipe section 122.

[0063] In addition, the distribution and connection relationship of the internal components of the aerosol generating device 10 can refer to another application filed by the applicant on the same day as the present application, entitled "Electronic atomization device and aerosol generating device".
