Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and in particular to an atomizer and an electronic atomization device. Background Technology

[0002] An electronic atomizing device is a device that uses an atomizing component to heat an aerosol generating matrix, thereby atomizing the heated aerosol generating matrix to generate an aerosol for the user to inhale.

[0003] Electronic atomization devices typically include an atomizer and a main unit. The main unit is connected to the atomizer so that the atomizer can be powered and controlled by the main unit. In existing technologies, the liquid guiding structure usually connects a liquid guiding component connected to the heating element to a liquid storage component within the liquid storage chamber. This guides the aerosol-generating matrix in the liquid storage component to the heating element. Additionally, liquid guiding holes are provided on the atomizer support to allow the aerosol-generating matrix in the liquid storage component to enter the guiding component and flow to the heating element. In areas without guiding holes or a guiding component, the aerosol-generating matrix in the liquid storage component cannot flow smoothly to the guiding component, resulting in a high residual rate of the aerosol-generating matrix in the liquid storage component.

The heating element is disposed inside the first liquid guiding component. The second liquid guiding element is disposed between the outside of the fixed tube and the liquid storage element, and the liquid guiding rate of the second liquid guiding element is greater than the liquid guiding rate of the liquid storage element, so as to guide the aerosol generating matrix contained in the liquid storage element to the first liquid guiding element.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0029] Please see Figure 1-3As shown, in a first aspect, this application provides an atomizer 100, the atomizer 100 having a receiving space 10, and the atomizer 100 including a liquid storage component 20, an atomizing component 30 and a second liquid guiding component 40, the liquid storage component 20 being disposed within the receiving space 10 and used to contain an aerosol generating matrix; the atomizing component 30 including a fixing tube 31, a first liquid guiding component 32 and a heating element 33. The fixed tube 31 passes through the liquid storage component 20 and has a liquid inlet 311. The aerosol generating matrix contained in the liquid storage component 20 can enter the first liquid guiding component 32 through the liquid inlet 311. The first liquid guiding component 32 is at least partially disposed inside the fixed tube 31 and covers the liquid inlet 311. The heating element 33 is disposed inside the first liquid guiding component 32. The first liquid guiding component 32 is used to guide the aerosol generating matrix contained in the liquid storage component 20 to flow to the heating element 33, so that the heating element 33 can heat the contacted aerosol generating matrix when energized, so that the heated aerosol generating matrix is ​​atomized to generate aerosol. The second liquid guiding component 40 is disposed outside the fixed tube 31 and between the liquid storage component 20, and the liquid guiding rate of the second liquid guiding component 40 is greater than the liquid guiding rate of the liquid storage component 20, so as to guide the aerosol generating matrix contained in the liquid storage component 20 to the first liquid guiding component 32.

[0030] By at least partially placing the first liquid guiding member 32 inside the fixed tube 31 and placing the second liquid guiding member 40 between the outside of the fixed tube 31 and the liquid storage member 20, and setting the liquid guiding rate of the second liquid guiding member 40 to be greater than the liquid guiding rate of the liquid storage member 20, the aerosol generating matrix contained in the liquid storage member 20 can be quickly replenished to the first liquid guiding member 32 through the second liquid guiding member 40. This ensures that the first liquid guiding member 32 contains sufficient aerosol generating matrix, thereby preventing the heating element 33 from dry burning and fully utilizing the aerosol generating matrix contained in the liquid storage member 20, reducing the residual rate of the aerosol generating matrix in the liquid storage member 20.

[0031] Please see Figure 4-6As shown in the embodiment of this application, the second liquid guiding member 40 has an opening 41, the fixed tube 31 has a groove 312, and the first liquid guiding member 32 includes a first part 321 and a second part 322. The first part 321 is disposed in the fixed tube 31 and covers the liquid inlet hole 311. The second part 322 is connected to the first part 321. The second part 322 extends out of the fixed tube 31 from the groove 312 and is at least partially located in the opening 41, so that the second liquid guiding member 40 and the second part 322 of the first liquid guiding member 32 are close to or in contact with each other. This allows the second liquid guiding member 40 and the first liquid guiding member 32 to guide the aerosol generation matrix from the liquid inlet hole or from the opening 41, thereby increasing the liquid guiding area between the first liquid guiding member 32 and the second liquid guiding member 40 and improving the liquid guiding efficiency between the second liquid guiding member 40 and the first liquid guiding member 32.

[0032] In addition, by providing the opening 41 at the second part 322 corresponding to the second liquid guiding component 40, it is also convenient to connect the second liquid guiding component 40 to the outside of the fixed tube 31, reducing the installation difficulty of the second liquid guiding component 40 and improving the installation efficiency of the second liquid guiding component 40.

[0033] In the embodiments of this application, the first liquid guiding member 32, the second liquid guiding member 40, and the liquid storage member 20 can all be made of cotton material or porous material.

[0034] Please see Figure 3 as well as Figure 7 As shown in the embodiment of this application, the second portion 322 passes through the opening 41 and extends into the liquid storage component 20, so that the aerosol generating matrix contained in the liquid storage component 20 can flow directly through the second portion 322 to the first portion 321, and be heated and atomized by the heating element 33 in the energized state to generate aerosol, and further improve the efficiency of the aerosol generating matrix contained in the liquid storage component 20 flowing to the first portion 321.

[0035] The liquid storage component 20 has a slit 21, which is positioned opposite the slot 312, so that the second part 322 can directly extend into the slit 21 after passing through the opening 41.

[0036] In embodiments of this application, the second part 322 may simply extend into the opening 41 and may or may not contact the liquid storage component 20.

[0037] Please see Figure 3As shown in the embodiment of this application, the opening 41 has a larger opening than the slot 312, so that the second liquid guide 40 can be adapted to the second part 322 of different lengths. That is to say, the second part 322 can extend out of the mounting tube or not extend out of the mounting tube, and the second liquid guide 40 can be connected between the outside of the mounting tube and the liquid storage component 20.

[0038] Wherein, when the second part 322 extends only into the opening 41, or when the second part 322 passes through the opening 41 and extends into the slit 21, the second liquid guide 40 approaches or contacts the second part 322 at the opening 41, so that the second liquid guide 40 can guide the aerosol generating matrix of the liquid storage 20 that is not directly facing the area of ​​the liquid inlet 311 to the opening 41, and then guide it through the second part 322 to the first part 321.

[0039] In the embodiments of this application, the first liquid guiding member 32 includes a first portion 321 and at least one second portion 322, each second portion 322 being connected to the first portion 321; the fixing tube 31 is provided with a slot 312 corresponding to each second portion 322, and the second liquid guiding member 40 is provided with an opening 41 corresponding to each second portion 322. When the liquid guiding member includes only one second portion 322, only one slot 312 is provided on the fixing tube 31; when the liquid guiding member includes multiple second portions 322, a slot 312 is provided on the fixing tube 31 corresponding to each second portion 322, and each second portion 322 extends out of the fixing tube 31 from a corresponding slot 312. By providing multiple second portions 322, the first liquid guiding member 32, with the cooperation of the second liquid guiding member 40, can more quickly guide the aerosol generating matrix contained in the liquid storage member 20 to the heating member 33.

[0040] Please see Figure 2-3 as well as Figure 6 As shown in the embodiment of this application, the first liquid guiding member 32 includes a first portion 321 and a second portion 322. The second portion 322 extends out of the fixing tube 31 from the slot 312 and extends into the liquid storage member 20 through the opening 41. The cross-section of the second liquid guiding member 40 along the extension direction of the fixing tube 31 is C-shaped, so that the second liquid guiding member 40 can be directly attached to the outside of the mounting tube from the opening 41, thereby improving the assembly efficiency of the second liquid guiding member 40.

[0041] In the embodiments of this application, a plurality of liquid inlet holes 311 are provided on the periphery of the fixed tube 31, and the second liquid guiding member 40 covers all the liquid inlet holes 311 on the outside of the fixed tube 31. The plurality of liquid inlet holes 311 are evenly distributed so that there is a larger liquid guiding area between the second liquid guiding member 40 and the first liquid guiding member 32, and the second liquid guiding member 40 can evenly guide the aerosol generating matrix contained in the liquid storage member 20 to the first liquid guiding member 32, thereby enabling the first liquid guiding member 32 to uniformly and stably supply the aerosol generating matrix to the heating member 33.

[0042] In the embodiments of this application, the atomizing component 30 further includes a fixing member 34 and a limiting tube 35. The fixing member 34 and the limiting tube 35 are respectively inserted into opposite ends of the fixing tube 31, and a plurality of fixing holes 36 are formed between the outer wall of the fixing member 34 and the inner wall of the fixing tube 31. Each pin 331 of the heating element 33 passes through one of the fixing holes 36 to extend out of the fixing tube 31. The end of the limiting tube 35 away from the fixing member 34 extends out of the liquid storage component 20 to allow the generated aerosol to flow and to prevent the aerosol generating matrix contained in the liquid storage component 20 from flowing directly from the limiting tube 35 to the heating element 33.

[0043] Please see Figure 1-3 As shown in the embodiment of this application, the atomizer 100 includes a first shell 50 and a sealing connector 60. The sealing connector 60 is sealed to the opening 41 end of the first shell 50 and forms the receiving space 10 with the first shell 50. The liquid storage component 20 is disposed in the receiving space 10. The end of the fixing tube 31 near the sealing connector 60 is sealed and inserted into the sealing connector 60. The sealing connector 60 has a through hole 61 communicating with the fixing tube 31. The through hole 61 is used to allow external airflow to enter the atomizing assembly 30, so that the airflow entering the fixing tube 31 can mix with the generated aerosol in the fixing tube 31 and flow out of the atomizer 100 under the action of suction.

[0044] In an embodiment of this application, the atomizer 100 further includes a second shell 70, in which the first shell 50 and the sealing connector 60 are both disposed. The second shell 70 has a mouthpiece 71, which is connected to the end of the fixed tube 31 away from the sealing connector 60, so that the airflow mixed with aerosol in the fixed tube 31 can flow out of the atomizer 100 from the mouthpiece 71.

[0045] Please refer to 8-9 and the combination Figure 1-7As shown, in a second aspect, this application also provides an electronic atomizing device 1000, which includes the atomizer 100 described in any of the above claims. Therefore, the electronic atomizing device 1000 has all the above-mentioned beneficial effects, which will not be repeated here.

[0046] In the embodiments of this application, the second shell 70 further forms a power supply compartment 72 and an installation space 73. The electronic atomizing device 1000 also includes a control circuit board 200 and a power supply 300. The power supply 300 is disposed in the power supply compartment 72, and the control circuit board 200 is disposed in the installation space 73. The control circuit board 200 is electrically connected to the power supply 300 and the atomizer 100, respectively.

[0047] Please see Figure 9 As shown in the embodiments of this application, the electronic atomizing device 1000 further includes an air regulating component 400, which regulates the airflow entering the atomizer 100. The air regulating component 400 includes an air regulating element 410, a sealing element 420, and a mounting element 430. The mounting element 430 and the sealing element 420 are respectively disposed within the mounting space 73. The control circuit board 200 is disposed between the sealing element 420 and the mounting element 430. The sealing element 420 passes through the control circuit board 200 and the mounting element 430 respectively and is connected to the air regulating element 410. The air regulating element 410 has at least one air inlet 4101, and the sealing element 420 has an air passage that communicates with the through hole 61. The air passage can communicate with the air inlet 4101. The air regulating component 410 moves relative to the mounting component 430 to block the air inlet 4101 or open at least part of the air inlet 4101, thereby controlling the airflow entering the electronic atomizing device 1000.

[0048] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0049] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0050] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
