Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, in particular to an atomization device and an aerosol generating device. Background Art

[0002] The smoke from burning cigarettes contains harmful substances such as tar, which can cause great harm to the human body if inhaled for a long time. In order to overcome the harmful substances produced by burning cigarettes, low-harm cigarette substitutes such as e-cigarettes with e-liquid and heat-not-burn e-cigarettes have emerged.

[0003] The traditional atomization device is mainly composed of an atomizer and a body component. The atomizer generally includes a liquid storage component and an atomization component. The liquid storage component is used to store the atomizable matrix, and the atomization component is used to heat and atomize the atomizable matrix to form an aerosol that can be consumed by the smoker; the body component is used to provide energy to the atomization component. Since the amount of atomized matrix stored in the liquid storage component is limited and cannot meet the needs of users with large suction volumes, a liquid storage bottle that can add atomized matrix has appeared, and the liquid storage component also needs to have an opening for docking with the liquid storage bottle.

[0004] However, after the liquid storage bottle in the traditional solution injects the atomizing matrix into the atomizing device, there are problems such as uneven distribution of the atomizing matrix in the liquid storage part, and the atomizing matrix easily flows out from the opening and leaks.

[0005] BACKGROUND OF THE PRESENT APPLICATION The above information disclosed is only used to understand the background of the concept of the present application, and does not indicate or imply that it contains information of the prior art. Utility Model Content

[0006] Based on this, it is necessary to provide an atomization device and an aerosol generating equipment to address the above problems.

[0007] An atomizing device, comprising:

[0008] A shell, wherein the shell has a top and a bottom, and the shell is provided with an atomization passage passing through the top and the bottom;

[0009] A liquid storage member, the liquid storage member is arranged in the housing and the atomization channel passes through the liquid storage member, the liquid storage member is used to absorb and store the atomized matrix and transfer the atomized matrix to the atomization channel;

[0010] An atomizing component, which is disposed in the atomizing channel and is used to atomize the atomizing matrix to generate an aerosol;

[0011] A liquid-blocking component is embedded in the bottom of the shell, and is provided with a liquid inlet hole for connecting to a liquid storage bottle. One end of the liquid inlet hole extends into the shell, and the end surface of the end of the liquid-blocking component extending into the shell is a liquid-blocking surface. In the height direction of the shell, the liquid-blocking surface is higher than the bottom surface of the liquid storage component.

[0012] The above-mentioned atomizing device of the present application can at least achieve the following beneficial effects: the liquid-blocking member is embedded in the bottom of the shell, one end of the liquid inlet hole provided thereon extends into the shell, and the liquid inlet hole can be connected to the liquid storage bottle. When the atomizing device is inverted, the atomized matrix in the liquid storage bottle can be injected into the shell from the liquid inlet hole and absorbed by the liquid storage member. The atomizing device is not inverted during normal use, that is, the opening of the liquid inlet hole faces downward. At this time, under the action of gravity, the saturation of the atomized matrix in the lower area of ​​the liquid storage member will be higher than the saturation of the atomized matrix in the upper area of ​​the liquid storage member. It is understandable that if the liquid inlet hole is lower than or flush with the bottom surface of the liquid storage component in the height direction, the atomized matrix at the bottom of the liquid storage component is very easy to seep out directly, resulting in leakage problems; and the liquid-blocking component provided in the present application particularly emphasizes that its liquid-blocking surface is higher than the bottom surface of the liquid storage component in the height direction of the shell. Therefore, even if the atomized matrix at the bottom of the liquid storage component wants to flow out from the liquid inlet hole, it needs to bypass the upper end surface of the liquid-blocking component, that is, bypass the liquid-blocking surface. In other words, the liquid-blocking surface of the liquid-blocking component is higher than the bottom surface of the liquid storage component in the height direction of the shell, which can intercept the atomized matrix at the bottom of the liquid storage component and reduce the risk of leakage.

[0013] In one of the embodiments, in the height direction of the shell, the ratio of the minimum distance between the liquid blocking surface and the top surface of the liquid storage component to the minimum distance between the liquid blocking surface and the bottom surface of the liquid storage component is 0.25-4. The consideration for such a setting is that if the relative position of the liquid blocking surface of the liquid blocking part in the shell is too high, it will affect the speed at which the injected atomized matrix is ​​absorbed by the liquid storage component and the uniformity of the distribution of the atomized matrix in the liquid storage component; if the relative position of the liquid blocking surface of the liquid blocking part in the shell is too low, its blocking effect on the atomized matrix at the bottom of the liquid storage component may be very limited. Therefore, the ratio of the minimum distance between the liquid blocking surface and the top surface of the liquid storage component to the minimum distance between the liquid blocking surface and the bottom surface of the liquid storage component selected in this embodiment is obtained after careful consideration, which is a relatively balanced range of the absorption speed of the atomized matrix by the liquid storage component, the uniformity of the distribution of the atomized matrix in the liquid storage component, and the blocking effect of the liquid blocking component on the atomized matrix.

[0014] In one embodiment, the top surface of the liquid storage member is spaced apart from the shell and a liquid flow space is formed. When the atomizing device is to be filled with liquid, the atomizing device is inverted, and the atomized matrix in the liquid storage bottle flows in from the liquid inlet hole. The atomized matrix can flow into the liquid flow space in large quantities under the action of gravity, and then quickly disperse to the end surface of the entire liquid storage member through the liquid flow space, which is conducive to the atomized matrix being quickly and evenly absorbed into the liquid storage member.

[0015] In one embodiment, the atomization device further comprises a support member, and either the housing or the liquid storage member is fixed to the support member, the support member is disposed in the liquid flow space, and the support member is supported between the housing and the top surface of the liquid storage member. The support member can play a supporting role to maintain the existence of the liquid flow space.

[0016] In one embodiment, the liquid storage element further has a liquid passage, and any part of the liquid passage in the height direction of the shell is higher than the liquid blocking surface. When the atomizing device is to be filled with liquid, the liquid passage is hollow, and the flow speed of the atomized matrix in the liquid passage is faster, that is, the liquid passage is conducive to the rapid conduction of the atomized matrix in the liquid storage element, and is conducive to the uniform and rapid absorption of the atomized matrix by the liquid storage element.

[0017] In one embodiment, the number of the liquid passage channels is set to be multiple, and the multiple liquid passage channels are arranged at intervals. By reasonably increasing the number of liquid passage channels, the absorption speed of the liquid storage component can be further improved, and the uniform distribution of the atomized matrix in the liquid storage component can be further improved.

[0018] In one of the embodiments, the length extension direction of the liquid passage is perpendicular to the height direction of the shell.

[0019] In one embodiment, the liquid passage and the atomization passage are isolated from each other.

[0020] In one embodiment, the liquid storage element includes at least one of oil storage cotton, porous ceramics, and porous fiber liquid storage elements.

[0021] In one embodiment, a portion of the liquid blocking member is spaced apart from the liquid storage member and encloses the liquid collecting chamber. The liquid collecting chamber can collect the atomized matrix outside the bottom of the liquid storage member to prevent the atomized matrix from flowing directly out of the liquid inlet hole, and at the same time facilitates the atomized matrix in the liquid collecting chamber to be absorbed by the liquid storage member again.

[0022] In one embodiment, the liquid-blocking member includes a first part and a second part both embedded in the bottom of the shell, the second part is stacked above the first part, the top surface of the second part is a liquid-blocking surface, the top surface of the second part is provided with the liquid inlet hole that runs through the first part and the second part, the first part is in contact with the liquid storage member, and the second part is spaced apart from the liquid storage member and encloses to form a liquid collecting chamber. For example, the first part of the liquid-blocking member is in close contact with the bottom end of the material storage member, and the second part of the liquid-blocking member can be an inclined surface on one side facing the liquid storage member, and the inclined surface is inclined in a direction away from the liquid storage member, so that the inclined surface can be spaced apart from the surface of the liquid storage member to enclose to form a liquid collecting chamber. For another example, the first part of the liquid-blocking member is in close contact with the bottom end of the material storage member, and the second part of the liquid-blocking member can be a curved surface on one side facing the liquid storage member, and the second part will not be in close contact with the surface of the liquid storage member, so that it can be spaced apart from the surface of the liquid storage member to enclose to form a liquid collecting chamber.

[0023] In one embodiment, the liquid-blocking component includes a first part and a second part both embedded in the bottom of the shell, the second part is stacked above the first part, the top surface of the second part is a liquid-blocking surface, the top surface of the second part is provided with the liquid inlet hole that passes through the first part and the second part, the first part and the second part are formed with a stepped groove on one side close to the liquid storage component, and the groove wall of the stepped groove is spaced apart from the liquid storage component and encloses to form a liquid collecting cavity.

[0024] In one embodiment, the top surface of the liquid storage member is concave to form a notch, and the bottom surface of the notch is lower than the liquid blocking surface in the height direction.

[0025] In one embodiment, the liquid storage component includes a liquid storage body and an abutment portion connected to the liquid storage body, the abutment portion protrudes from the side of the liquid storage body, the abutment portion abuts against the liquid blocking component, and the upper end surface of the abutment portion is higher than the liquid blocking surface in the height direction.

[0026] In one embodiment, the atomizing device further comprises a bottom plate, the bottom plate is connected to the liquid blocking member, the bottom plate cover is arranged at the bottom of the housing, and an air inlet connected to the atomizing channel is opened on the bottom plate. The bottom plate and the liquid blocking member can be arranged in one piece.

[0027] In one embodiment, the atomization device further includes a spacer, which is embedded in the bottom of the shell and located between the liquid blocking member and the liquid storage member. The liquid storage member, the spacer and the liquid blocking member together enclose the liquid collecting chamber.

[0028] The present application also provides an aerosol generating device, which includes a liquid storage bottle, a power supply device and an atomization device as described in any of the above embodiments, wherein the atomization device is detachably connected to the liquid storage bottle, and the liquid outlet end of the liquid storage bottle is inserted into the liquid inlet hole.

[0029] The above-mentioned aerosol generating device, because it includes the atomizing device described in any of the above-mentioned embodiments, the aerosol generating device also includes at least the following beneficial effects: when the atomizing matrix in the liquid storage bottle is used up, another liquid storage bottle with the atomizing matrix can be replaced and inserted into the liquid inlet hole of the atomizing device. The liquid blocking member of the atomizing device is embedded in the bottom of the housing, and one end of the liquid inlet hole provided thereon extends into the housing, and the liquid inlet hole can be connected to the liquid storage bottle. When the atomizing device is inverted, the atomizing matrix in the liquid storage bottle can be injected into the housing from the liquid inlet hole and absorbed by the liquid storage member. The atomizing device is not inverted during normal use, that is, the opening of the liquid inlet hole faces downward. At this time, under the action of gravity, the saturation of the atomizing matrix in the area below the liquid storage member will be higher than the saturation of the atomizing matrix in the area above the liquid storage member. It is understandable that if the liquid inlet hole is lower than or flush with the bottom surface of the liquid storage component in the height direction, the atomized matrix at the bottom of the liquid storage component is very easy to seep out directly, resulting in leakage problems; and the liquid-blocking component provided in the present application particularly emphasizes that its liquid-blocking surface is higher than the bottom surface of the liquid storage component in the height direction of the shell. Therefore, even if the atomized matrix at the bottom of the liquid storage component wants to flow out from the liquid inlet hole, it needs to bypass the upper end surface of the liquid-blocking component, that is, bypass the liquid-blocking surface. In other words, the liquid-blocking surface of the liquid-blocking component is higher than the bottom surface of the liquid storage component in the height direction of the shell, which can intercept the atomized matrix at the bottom of the liquid storage component and reduce the risk of leakage.

[0048] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0049] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, the present application provides an atomization device 11 , which includes a housing 100 , a liquid storage component 200 , an atomization assembly 300 and a liquid blocking component 400 . The shell 100 has a top and a bottom, and the shell 100 is provided with an atomization channel 110 that runs through the top and the bottom; the liquid storage component 200 is arranged in the shell 100 and the atomization channel 110 runs through the liquid storage component 200, and the liquid storage component 200 is used to absorb and store the atomization matrix and transmit the atomization matrix to the atomization channel 110; the atomization assembly 300 is arranged in the atomization channel 110 and is used to atomize the atomization matrix to generate an aerosol; the liquid blocking component 400 is embedded in the bottom of the shell 100, and the liquid blocking component 400 is provided with a liquid inlet hole 430 for connecting with the liquid storage bottle 13, one end of the liquid inlet hole 430 extends into the shell 100, and the end surface of the end of the liquid blocking component 400 extending into the shell 100 is a liquid blocking surface 431, and in the height direction of the shell 100, the liquid blocking surface 431 is higher than the bottom surface of the liquid storage component 200. The atomized matrix may refer to a material that can be delivered and provide volatile components through the liquid storage member 200, such as e-liquid, which can be atomized to form an aerosol that can be inhaled by the user. The liquid storage member 200 may include but is not limited to at least one of oil storage cotton, porous ceramics, and porous fiber liquid storage members 200. For example, the liquid storage member 200 may be made of a porous material with a certain porosity, such as porous ceramics or porous glass, which presents a "porous" morphology at the microscopic level and transmits the atomized matrix internally through capillary action.

[0050] The above-mentioned atomizing device 11 of the present application can at least achieve the following beneficial effects: the liquid blocking member 400 is embedded in the bottom of the housing 100, one end of the liquid inlet hole 430 opened thereon extends into the housing 100, and the liquid inlet hole 430 can be connected to the liquid storage bottle 13. When the atomizing device 11 is inverted, the atomized matrix in the liquid storage bottle 13 can be injected into the housing 100 from the liquid inlet hole 430 and absorbed by the liquid storage member 200. The atomizing device 11 is not inverted during normal use, that is, the opening of the liquid inlet hole 430 faces downward. At this time, under the action of gravity, the saturation of the atomized matrix in the lower area of ​​the liquid storage member 200 will be higher than the saturation of the atomized matrix in the upper area of ​​the liquid storage member 200. It is understandable that if the liquid inlet hole 430 is lower than or flush with the bottom surface of the liquid storage component 200 in the height direction, the atomized matrix at the bottom of the liquid storage component 200 is very easy to directly seep out, resulting in leakage problems; and the liquid blocking component 400 provided in the present application particularly emphasizes that its liquid blocking surface 431 is higher than the bottom surface of the liquid storage component 200 in the height direction of the shell 100. Therefore, even if the atomized matrix at the bottom of the liquid storage component 200 wants to flow out from the liquid inlet hole 430, it needs to bypass the upper end surface of the liquid blocking component 400, that is, bypass the liquid blocking surface 431. In other words, the liquid blocking surface 431 of the liquid blocking component 400 is higher than the bottom surface of the liquid storage component 200 in the height direction of the shell 100, which can intercept the atomized matrix at the bottom of the liquid storage component 200 and reduce the risk of leakage.

[0051] Specifically, Figure 4 As shown, in some embodiments, in the height direction of the housing 100, the ratio of the minimum distance H1 between the liquid blocking surface 431 and the top surface of the liquid storage part 200 to the minimum distance H2 between the liquid blocking surface 431 and the bottom surface of the liquid storage part 200 is 0.25-4. The consideration for such a setting is that if the relative position of the liquid blocking surface 431 of the liquid blocking part in the housing 100 is too high, it will affect the speed at which the injected atomized matrix is ​​absorbed by the liquid storage part 200 and the uniformity of the distribution of the atomized matrix in the liquid storage part 200; if the relative position of the liquid blocking surface 431 of the liquid blocking part in the housing 100 is too low, its blocking effect on the atomized matrix at the bottom of the liquid storage part 200 may be very limited. Therefore, the ratio of the minimum distance H1 between the liquid blocking surface 431 and the top surface of the liquid storage component 200 to the minimum distance H2 between the liquid blocking surface 431 and the bottom surface of the liquid storage component 200 selected in this embodiment is obtained after careful consideration, and is a relatively balanced range for the absorption rate of the atomized matrix by the liquid storage component 200, the uniformity of the distribution of the atomized matrix in the liquid storage component 200, and the blocking effect of the liquid blocking component 400 on the atomized matrix.

[0052] See also Figure 5In some embodiments, the top surface of the liquid storage member 200 is spaced apart from the housing 100 and a liquid overflow space 210 is formed. When the atomizing device 11 is to be filled with liquid, the atomizing device 11 is inverted, and the atomized matrix in the liquid storage bottle 13 flows in from the liquid inlet hole 430. The atomized matrix can flow into the liquid overflow space 210 in large quantities under the action of gravity, and then quickly disperse to the end surface of the entire liquid storage member 200 through the liquid overflow space 210, which is conducive to the atomized matrix being quickly and evenly absorbed into the liquid storage member 200.

[0053] Specifically, in some embodiments, the atomization device 11 further includes a support member, and either the housing 100 or the liquid storage member 200 is fixed to the support member, and the support member is disposed in the liquid flow space 210, and the support member is supported between the housing 100 and the top surface of the liquid storage member 200. The support member can play a supporting effect and maintain the existence of the liquid flow space 210.

[0054] See also Figure 6 In some embodiments, a liquid passage 220 is further provided in the liquid storage member 200, and any part of the liquid passage 220 in the height direction of the housing 100 is higher than the liquid blocking surface 431. When the atomizing device 11 is to be filled with liquid, the liquid passage 220 is hollow, and the flow speed of the atomized matrix in the liquid passage 220 is faster, that is, the liquid passage 220 is conducive to the rapid conduction of the atomized matrix in the liquid storage member 200, and is conducive to the uniform and rapid absorption of the atomized matrix by the liquid storage member 200.

[0055] Furthermore, if Figure 6 As shown, in some embodiments, the number of the liquid passage channels 220 is set to be multiple, and the multiple liquid passage channels 220 are arranged at intervals. By reasonably increasing the number of liquid passage channels 220, the absorption speed of the liquid storage member 200 can be further improved, and the uniform distribution of the atomized matrix in the liquid storage member 200 can be further improved.

[0056] Furthermore, if Figure 6 As shown, in some embodiments, the length extension direction of the liquid passage 220 is perpendicular to the height direction of the housing 100 .

[0057] Furthermore, in some embodiments, the liquid passage 220 is isolated from the atomization channel 110, that is, the liquid passage 220 is not directly connected to the atomization channel 110. While the liquid passage 220 is used to improve the conduction effect of the atomized matrix, the atomized matrix in the liquid passage 220 can be prevented from directly entering the atomization channel 110.

[0058] See also Figure 7 , Figure 8 , Fig. 9and Fig.10 In some embodiments, a portion of the liquid blocking member 400 is spaced apart from the liquid storage member 200 and encloses the liquid collecting chamber 120. The arrangement of the liquid collecting chamber 120 can collect the atomized matrix outside the bottom of the liquid storage member 200, prevent the atomized matrix from directly flowing out of the liquid inlet hole 430, and at the same time facilitate the atomized matrix in the liquid collecting chamber 120 to be absorbed by the liquid storage member 200 again.

[0059] Furthermore, in some embodiments, the liquid-blocking member 400 includes a first part 410 and a second part 420 both embedded in the bottom of the shell 100, the second part 420 is stacked above the first part 410, the top surface of the second part 420 is a liquid-blocking surface 431, the top surface of the second part 420 is provided with the liquid inlet hole 430 that passes through the first part 410 and the second part 420, the first part 410 is in contact with the liquid storage member 200, and the second part 420 is spaced apart from the liquid storage member 200 and encloses to form a liquid collecting chamber 120.

[0060] For example, Figure 7 and Fig.11 As shown, the first part 410 of the liquid-blocking member 400 is in close contact with the bottom end of the material storage member, and the second part 420 of the liquid-blocking member 400 can be a slope facing the liquid storage member 200, and the slope is inclined in a direction away from the liquid storage member 200. The slope can be spaced apart from the surface of the liquid storage member 200 to enclose the liquid collecting chamber 120.

[0061] For another example, the first portion 410 of the liquid-blocking member 400 is in close contact with the bottom end of the material storage member, and the second portion 420 of the liquid-blocking member 400 may be a curved surface facing the liquid storage member 200. The second portion 420 will not be in close contact with the surface of the liquid storage member 200, and can be spaced apart from the surface of the liquid storage member 200 to form a liquid collecting chamber 120.

[0063] See also Fig.10 , Fig.11 and Fig.12 In some embodiments, the atomizing device 11 further includes a bottom plate 600, the bottom plate 600 is connected to the liquid blocking member 400, the bottom plate 600 is covered on the bottom of the housing 100, and an air inlet 610 connected to the atomizing channel 110 is opened on the bottom plate 600. The bottom plate 600 and the liquid blocking member 400 may be integrally arranged.

[0064] See also Fig. 9 and Fig.13 In some embodiments, the atomization device 11 further includes a spacer 500, which is embedded in the bottom of the shell 100 and located between the liquid blocking member 400 and the liquid storage member 200. The liquid storage member 200, the spacer 500 and the liquid blocking member 400 together enclose the liquid collecting chamber 120.

[0065] See also Fig.14 In some embodiments, the top surface of the liquid storage member 200 is concave to form a notch 230, and the bottom surface of the notch 230 is lower than the liquid blocking surface 431 in the height direction.

[0066] See also Fig.15 In some embodiments, the liquid storage member 200 includes a liquid storage body 201 and an abutment portion 202 connected to the liquid storage body 201, the abutment portion 202 protrudes from the side of the liquid storage body 201, the abutment portion 202 abuts against the liquid blocking member 400, and the upper end surface of the abutment portion 202 is higher than the liquid blocking surface 431 in the height direction.

[0067] In addition, if Figure 1 , Figure 2 and Figure 3 As shown, the present application also provides an aerosol generating device 10, which includes a liquid storage bottle 13, a power supply device 12 and an atomization device 11 as described in any of the above embodiments, wherein the atomization device 11 is detachably connected to the liquid storage bottle 13, and the liquid outlet end of the liquid storage bottle 13 is inserted into the liquid inlet hole 430.

[0068] The above-mentioned aerosol generating device 10, because it includes the atomizing device 11 described in any of the above-mentioned embodiments, the aerosol generating device 10 also includes at least the following beneficial effects: when the atomizing matrix in the liquid storage bottle 13 is used up, another liquid storage bottle 13 with the atomizing matrix can be replaced and inserted into the liquid inlet hole 430 of the atomizing device 11.

When the atomizing device 11 is inverted, the atomizing matrix in the liquid storage bottle 13 can be injected into the housing 100 from the liquid inlet hole 430 and absorbed by the liquid storage member 200. The atomizing device 11 is not inverted during normal use, that is, the opening of the liquid inlet hole 430 faces downward. At this time, under the action of gravity, the saturation of the atomizing matrix in the lower area of ​​the liquid storage member 200 will be higher than the saturation of the atomizing matrix in the upper area of ​​the liquid storage member 200. It is understandable that if the liquid inlet hole 430 is lower than or flush with the bottom surface of the liquid storage component 200 in the height direction, the atomized matrix at the bottom of the liquid storage component 200 is very easy to directly seep out, resulting in leakage problems; and the liquid blocking component 400 provided in the present application particularly emphasizes that its liquid blocking surface 431 is higher than the bottom surface of the liquid storage component 200 in the height direction of the shell 100. Therefore, even if the atomized matrix at the bottom of the liquid storage component 200 wants to flow out from the liquid inlet hole 430, it needs to bypass the upper end surface of the liquid blocking component 400, that is, bypass the liquid blocking surface 431. In other words, the liquid blocking surface 431 of the liquid blocking component 400 is higher than the bottom surface of the liquid storage component 200 in the height direction of the shell 100, which can intercept the atomized matrix at the bottom of the liquid storage component 200 and reduce the risk of leakage.
