[0002] An electronic atomization device is an instrument that can heat an aerosol matrix to form an aerosol. Electronic atomization devices are divided into two types: refillable and non-refillable, depending on whether the aerosol matrix can be refilled. For refillable electronic atomization devices, when filling the liquid storage tank within the electronic atomization device with aerosol matrix, if the aerosol matrix enters too quickly, the pressure in the liquid storage tank will be too high, causing the aerosol matrix to enter the interior of the bracket through the holes in the bracket, thereby leaking. Therefore, how to avoid leakage when filling the aerosol matrix has become an urgent problem that needs to be solved. Utility Model Content

In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary, not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0040] See also Figure 1-10 As shown, the present application provides an electronic atomization device, which includes a housing, a flow guide 20, a liquid storage member 30, a buffer member 40 and an atomization assembly. The flow guide 20, the liquid storage member 30, the buffer member 40 and the atomization assembly are respectively accommodated in the housing.

[0041] Furthermore, the housing structure is formed with a liquid storage tank 11 and a liquid injection channel 12 that are interconnected. The liquid storage tank 11 is used to accommodate aerosol matrix, and the liquid injection channel 12 is used for allowing the aerosol matrix added to the liquid storage tank 11 to pass through.

[0042] The flow guide 20 is disposed in the liquid storage bin 11 and is configured to form a first air flow channel 21. The first air flow channel 21 is used for aerosol flow.

[0043] Furthermore, the first air flow channel 21 has an air outlet 211 , and the air outlet 211 is located in the liquid storage tank 11 . Therefore, the aerosol flowing out through the air outlet 211 will pass through the liquid storage tank 11 .

[0044] Furthermore, the housing is further configured to have a suction nozzle 13 having a second air flow channel 131 communicating with the liquid storage tank 11 and the outside of the device. The second air flow channel 131 is communicated with the first air flow channel 21 via the liquid storage tank 11.

[0045] Furthermore, the atomization assembly includes a bracket 51 and a heating assembly. The bracket 51 is housed within the liquid storage tank 11 and is a hollow structure with both ends open, so that the bracket 51 is configured to form a third airflow channel 511. The heating assembly is housed within the third airflow channel 511 and is used to heat the aerosol substrate entering the bracket 51, causing the heated aerosol substrate to be atomized to form an aerosol.

[0046] Furthermore, the bracket 51 is constructed with a liquid passage 512 connected to the third airflow channel 511. The aerosol matrix in the liquid storage tank 11 enters the bracket 51 through the liquid passage 512 and is heated by the heating component to be atomized to form an aerosol. The aerosol flows from the third airflow channel 511 through the first airflow channel 21, passes through the liquid storage tank 11, enters the second airflow channel 131, and finally flows out of the device through the second airflow channel 131.

[0047] Furthermore, the liquid storage component 30 is accommodated in the liquid storage tank 11, and the liquid storage component 30 covers the liquid hole 512, thereby locking the aerosol matrix in the liquid storage tank 11 to prevent the aerosol matrix in the liquid storage tank 11 from uncontrollably entering the interior of the bracket 51 through the liquid hole 512.

[0048] The buffer member 40 is disposed in the housing and is located on the flow path of the aerosol matrix from the injection channel 12 into the liquid storage tank 11 , so that the aerosol matrix added to the liquid storage tank 11 must pass through the buffer member 40 .

[0049] Furthermore, the buffer member 40 is configured to buffer the aerosol matrix flowing therethrough to reduce the flow velocity, thereby preventing the filled aerosol matrix from directly entering the first airflow channel 21 from the air outlet 211 .

[0050] Furthermore, the injection channel 12 includes an injection end 121. The second air flow channel 131 includes an air outlet end 1311, and the air outlet end 1311 and the injection end 121 are located on the same side of the housing.

[0051] When the aerosol matrix is ​​added to the liquid storage tank 11, the device will add the aerosol matrix with the nozzle 13 facing upward. Therefore, if the added aerosol matrix enters the first airflow channel 21 from the air outlet 211, it will enter the third airflow channel 511 along the first airflow channel 21.

[0052] Since the device is in a non-operating state when the aerosol matrix is ​​being filled, the aerosol matrix passing through the heating element will not be heated. Instead, this portion of the aerosol matrix will flow out of the third airflow channel 511 along the third airflow channel 511 toward the end away from the first airflow channel 21, thereby leaking.

[0053] Therefore, in this embodiment, the buffer member 40 can be provided to buffer and decelerate the aerosol matrix being filled, thereby preventing the aerosol matrix from entering the first airflow channel 21 through the air outlet 211 and leaking along the third airflow channel 511. Furthermore, the buffer member 40 can effectively filter the aerosol matrix being filled, thereby preventing particulate impurities from entering the liquid storage tank 11 during the filling process.

[0054] Further, see Figure 7-8 Combined with Figure 3 As shown, the bracket 51 is formed with a plurality of liquid holes 512 corresponding to the heating component structure. The heating component includes a heating element 521 and a liquid guide 522. The liquid guide 522 is provided between the bracket 51 and the heating element 521 and corresponds to the liquid holes 512.

[0055] Preferably, the liquid guiding member 522 also partially extends out of the bracket 51 and into the liquid storage member 30 , thereby increasing the efficiency of the aerosol matrix in the liquid storage tank 11 entering the interior of the bracket 51 .

[0056] Furthermore, the heating element 521 may be a resistive heating element and / or an electromagnetic induction heating element to heat the aerosol matrix on the liquid guiding element 522. The liquid guiding element 522 is made of cotton material.

[0057] Furthermore, by connecting the liquid storage tank 11 between the first air flow channel 21 and the second air flow channel 131, when the aerosol matrix is ​​added to the liquid storage tank 11, the gas in the liquid storage tank 11 will flow to the outside of the device through the second air flow channel 131 as the aerosol matrix is ​​gradually added.

[0058] Therefore, in this embodiment, it is possible to avoid providing an exhaust hole specifically used for filling the aerosol matrix, thereby simplifying the structure of the device and improving the anti-leakage effect of the liquid storage tank 11 for accommodating the aerosol matrix.

[0059] Furthermore, in the first embodiment, the buffer member 40 is made of a porous material such as cotton or ceramic. Therefore, the porous structure of the cotton or ceramic can be used to buffer and decelerate the aerosol matrix flowing through the cotton or ceramic.

[0060] Furthermore, in a second embodiment, the buffer member 40 is made of a porous material such as a metal mesh or a plastic mesh. When the aerosol substrate passes through the metal mesh or the plastic mesh, the surface tension of the porous structure of the metal mesh or the plastic mesh can be used to buffer and slow down the aerosol substrate. Both the metal mesh and the plastic mesh are food grade.

[0061] Further, see Figure 9 Combined with Figure 3 As shown, in the first embodiment, the device includes a connecting member 60 , which is disposed in the injection channel 12 and is configured to form a connecting hole 61 .

[0062] The buffer member 40 is received in the connecting hole 61 and is used to buffer the aerosol matrix flowing therethrough so as to reduce its flow velocity into the liquid storage tank 11 .

[0063] Furthermore, when the aerosol matrix is ​​added to the liquid storage tank 11 , the connecting hole 61 is used to connect the liquid injection device 200 , so that the aerosol matrix contained in the liquid injection device 200 enters the liquid storage tank 11 after the flow rate is reduced by the buffer 40 .

[0064] When the liquid storage tank 11 is not filled with the aerosol matrix, a sealing member 70 is connected to the connection hole 61. The sealing member 70 is used to seal the connection hole 61. This prevents the aerosol matrix in the liquid storage tank 11 from flowing out of the device through the connection hole 61.

[0065] In the second embodiment, the housing is formed with a first limit portion 14 corresponding to the injection channel 12 . The device includes a connector 60 , which is disposed in the injection channel 12 and forms a first installation space 15 with the first limit portion 14 .

[0066] The buffer member 40 is received within the first installation space 15, and the connector 60 is formed with a connection hole 61. When the aerosol matrix is ​​added to the liquid storage tank 11, the connection hole 61 is used to connect to the liquid injection device 200, so that the aerosol matrix contained in the liquid injection device 200 enters the liquid storage tank 11 after the flow rate is reduced by the buffer member 40.

[0067] When the liquid storage tank 11 is not filled with the aerosol matrix, a sealing member 70 is connected to the connection hole 61. The sealing member 70 is used to seal the connection hole 61. This prevents the aerosol matrix in the liquid storage tank 11 from flowing out of the device through the connection hole 61.

[0068] By limiting the installation of the buffer component 40 in the first installation space 15, the connecting component 60 and the injection channel 12 are cleverly utilized to achieve the limited installation of the buffer component 40, avoiding the need to set up a structure dedicated to installing the buffer component 40, thereby simplifying the assembly of the buffer component 40 and allowing the buffer component 40 to be quickly replaced as needed.

[0069] Furthermore, the connecting hole 61 is a through hole, and the connecting member 60 is formed with a connecting portion 611 and a second limiting portion 612 corresponding to the connecting hole 61. The connecting portion 611 is away from the buffer member 40, and the second limiting portion 612 is close to the buffer member 40.

[0070] When the aerosol matrix is ​​added to the liquid storage chamber 11, the connecting portion 611 is used to connect to the liquid injection device 200, and the second limiting portion 612 is used to limit the open end 210 of the liquid injection device 200. This prevents the liquid injection device 200 from excessively entering the connecting hole 61, causing the open end 210 to squeeze the buffer member 40 and affect the buffering effect of the buffer member 40 on the aerosol matrix.

[0071] Furthermore, when the aerosol matrix is ​​not added to the liquid storage tank 11 , the connecting portion 611 is connected to the hole sealing member 70 , and the second limiting portion 612 is used to limit the end of the hole sealing member 70 , thereby preventing the sealing member from excessively entering the connecting hole 61 .

[0072] In one embodiment, the connecting portion 611 is an internal thread, and the sealing member 70 and the liquid injection device 200 are respectively provided with external threads that match the internal thread.

[0073] When the aerosol matrix is ​​added to the liquid storage tank 11 , the external thread of the liquid injection device 200 is connected to the internal thread.

[0074] During the period when the aerosol matrix is ​​not added to the liquid storage tank 11 , the external thread of the sealing member 70 is connected to the internal thread.

[0075] Furthermore, in one embodiment, the liquid injection device 200 may be a container such as a bottle or a can that can accommodate the aerosol matrix.

[0076] Further, see Figure 5 as well as Figure 10 As shown, the buffer member 40 includes a first surface 41 and a second surface 42 opposite to each other. The first surface 41 abuts against the connecting member 60 , and the second surface 42 abuts against the first limiting portion 14 and at least partially contacts the liquid storage member 30 .

[0077] In one embodiment, the connector 60 has an abutting end 62 corresponding to the first surface 41. The first limiting portion 14 serves as a supporting surface. The connector 60 is sealed to the housing, and the abutting end 62 abuts against the first surface 41, and cooperates with the supporting surface to limit the position of the buffer 40.

[0078] Furthermore, a guide channel 19 is formed between the liquid storage tank 11 and the liquid storage member 30. The end of the guide channel 19 near the liquid injection channel 12 is covered by the second surface 42. This allows the aerosol substrate that flows out of the buffer member 40 and corresponds to the guide channel 19 to quickly move to the bottom of the liquid storage tank 11, thereby improving the efficiency of aerosol substrate injection.

[0079] Furthermore, the buffer member 40 includes a side surface. The side surface is connected between the edge of the first surface 41 and the edge of the second surface 42. The side surface is at least partially exposed within the liquid storage tank 11, so that the portion of the aerosol substrate that enters the buffer member 40 can also enter the liquid storage tank 11 through the side surface corresponding to the exposed portion of the liquid storage tank 11.

[0080] In some embodiments, the buffer component 40 and the liquid storage component 30 may be an integrated structure, wherein the buffer component 40 and the liquid storage component 30 are both made of cotton material; or the buffer component 40 and the liquid storage component 30 are both made of non-woven material.

[0081] Furthermore, the housing includes an inner shell 16 and an outer shell 17. The inner shell 16 is disposed inside the outer shell 17, and the inner shell 16 is configured to form the liquid storage tank 11 and the liquid injection channel 12.

[0082] The side surface includes a first side portion 431 and a second side portion, wherein the first side portion 431 is exposed to the liquid storage tank 11. The inner shell 16 is provided with a matching limiting side wall 161 corresponding to the second side portion, and the second portion can be in contact with the limiting side wall 161.

[0083] Furthermore, in one embodiment, the buffer member 40 is cylindrical, wherein, along the radial direction of the buffer member 40, the arc length of the second side portion is greater than the arc length of the first side portion 431. Therefore, when the buffer member 40 is installed in the first installation space 15, the limiting sidewall 161 can limit the buffer member 40 to prevent the buffer member 40 from moving toward the liquid storage tank 11.

[0084] For further information, please refer to Figure 3As shown, a second installation space 18 is formed between the inner shell 16 and the outer shell 17. The second installation space 18 is used to accommodate the power supply component 80 and the control component 90. The control component 90 is electrically connected to the power supply component 80 and the heating component.

[0085] Furthermore, the control component 90 is used to control the power supply component 80 to supply power to the heating component and control the heating component to work.

[0086] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0087] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0088] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
