Description

Technical Field

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

[0002] An electronic atomizing device is a device that heats an aerosol matrix through an atomizing unit, causing the heated aerosol matrix to be atomized into an aerosol for the user to inhale.

[0003] Electronic atomizing devices typically include an atomizing airway and a detection airway. The atomizing airway allows external airflow to pass through and mix with the generated aerosol, while the detection airway detects whether the electronic atomizing device is currently being drawn in. When the airflow sensor in the detection airway senses airflow movement, it sends a drawing signal back to the control unit. The control unit then controls the atomizing unit to heat the aerosol matrix based on the received drawing signal, causing the heated aerosol matrix to atomize and generate an aerosol that diffuses into the atomizing airway.

[0004] In existing electronic atomizing devices, the atomizing airway and the detection airway are partially shared, meaning they converge and connect within the device. However, not all the aerosol produced is expelled from the device; some remains in the atomizing airway and diffuses into the detection airway. Over time, this aerosol cools and condenses. As this condensate flows into the detection airway and towards the airflow sensor, it can cause the sensor to automatically activate or even be damaged. Therefore, the detection airway structure of existing electronic atomizing devices needs improvement. Utility Model Content

[0005] The main objective of this application is to provide an electronic atomization device to solve the problem of airflow sensors automatically starting due to the influence of condensate in the prior art.

[0006] This application provides an electronic atomizing device, the electronic atomizing device comprising:

[0007] The housing is configured to form an independent atomizing air channel and a detection air channel, and the first air outlet of the atomizing air channel and the second air outlet of the detection air channel are independently connected to the outside.

[0008] An airflow sensor, disposed within the detection airway, is used to detect changes in airflow within the detection airway; and

[0009] The atomizing unit is disposed within the atomizing air passage, and the control unit is disposed within the housing and is electrically connected to the airflow sensor and the atomizing unit, respectively. The control unit is used to control the atomizing unit to heat the aerosol matrix according to the signal fed back by the airflow sensor.

[0010] Furthermore, the airflow sensor is located in the middle of the detection airway.

[0011] Furthermore, the housing is configured to have a mounting hole, and the airflow sensor is disposed within the mounting hole;

[0012] The detection airway includes a detection hole and a main airway. The main airway connects the second air outlet end and the detection hole, and the detection hole connects the main airway and the mounting hole.

[0013] The main air passage has a blind end opposite to the second air outlet end, and the detection hole is connected to the side wall of the main air passage and is spaced a certain distance from the blind end.

[0014] Furthermore, the diameter of the detection hole is smaller than the diameter of the mounting hole.

[0015] Furthermore, the detection surface of the airflow sensor faces the detection hole.

[0016] Furthermore, a liquid-locking component is provided in the main air passage, which is used to lock in the liquid entering the detection air passage from the second air outlet.

[0017] And / or, the main airway is provided with an adsorption structure, which is used to absorb the liquid entering the detection airway from the second air outlet.

[0018] Furthermore, the atomizing airway includes a mouthpiece section and an atomizing section that are interconnected, the end of the mouthpiece section away from the atomizing section is the first air outlet end, and the atomizing unit is disposed in the atomizing section;

[0019] The housing is configured to have a suction nozzle portion, which is configured to include a suction nozzle section, a main air passage, a detection hole, and a second air outlet end, with the main air passage surrounding the outer periphery of the suction nozzle section.

[0020] Furthermore, the detection hole and the second air outlet are located on the same side of the nozzle section.

[0021] Furthermore, the atomizing unit is located in the atomizing section and away from the mouthpiece section;

[0022] The control unit includes a first control board and a second control board that are electrically connected. The first control board is disposed inside the housing and located at the air inlet end of the atomizing air channel. The second control board is disposed outside the atomizing air channel and extends along the air inlet end toward the first air outlet end.

[0023] The atomizing unit is electrically connected to the first control board, and the airflow sensor is electrically connected to the second control board.

[0024] Furthermore, the atomizing airway also includes an air intake section, which is connected to the end of the atomizing section away from the mouthpiece section, and the air intake section is configured to form the air intake end;

[0025] The electronic atomizing device further includes a control switch and an adjusting component. The control switch is located on the side of the first control plate away from the atomizing section. The adjusting component includes an operating part, an air regulating plate part, and a trigger part. The air regulating plate part is located on the side of the first control plate away from the atomizing section. The trigger part is located on the side of the air regulating plate part facing the first control plate and is connected to the control switch. The operating part is located on the air regulating plate part and, under the drive of an external force, drives the air regulating plate part and the trigger part to move synchronously, so that the adjusting component has a first position and a second position relative to the housing.

[0026] When the adjusting member is in the first position, the control switch is in the closed state, and the air regulating plate blocks the air intake end; when the adjusting member is in the second position, the control switch is in the open state, and the air regulating plate opens the air intake section.

[0027] In this application, by constructing independent atomizing air channels and detection air channels on the housing, and by setting the first outlet end of the atomizing air channel and the second outlet end of the detection air channel to be independently connected to the outside, the atomizing air channel and the detection air channel are completely independent and do not converge and connect on the housing. This prevents aerosols remaining in the atomizing air channel from entering the detection air channel during or after use, and also prevents the condensate formed by the cooling of the residual aerosols from flowing to the airflow sensor located in the detection air channel. This ensures that the airflow sensor will not self-start due to the influence of condensate and trigger the atomizing unit to work, resulting in aerosol loss and power loss, or even the phenomenon of condensate accumulating on the airflow sensor and damaging the airflow sensor.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. 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.

[0039] Please see Figure 1-2 As shown, this application provides an electronic atomizing device 100, which includes a housing 10, an airflow sensor 20, an atomizing unit 30, and a control unit 40. The airflow sensor 20, the atomizing unit 30, and the control unit 40 are respectively disposed within the housing 10. The airflow sensor 20 is used to detect changes in airflow within the detection airway 12; the control unit 40 is electrically connected to both the airflow sensor 20 and the atomizing unit 30, and is used to control the atomizing unit 30 to heat the aerosol matrix based on the signal fed back by the airflow sensor 20.

[0040] Furthermore, the housing 10 is configured to form an independent atomizing airway 11 and a detection airway 12, and the first air outlet 111 of the atomizing airway 11 and the second air outlet 121 of the detection airway 12 are independently connected to the outside; wherein, the airflow sensor 20 is disposed in the detection airway 12; and the atomizing unit 30 is disposed in the atomizing airway 11.

[0041] By constructing independent atomizing air channels 11 and detection air channels 12 on the housing 10, and setting the first air outlet 111 of the atomizing air channel 11 and the second air outlet 121 of the detection air channel 12 to be independently connected to the outside, the atomizing air channel 11 and the detection air channel 12 are completely independent and do not converge and connect on the housing 10. This avoids aerosols remaining in the atomizing air channel 11 from entering the detection air channel 12 during or after use, and also prevents the condensate formed by the cooling of the residual aerosols from flowing to the airflow sensor 20 located in the detection air channel 12. This ensures that the airflow sensor 20 will not automatically start due to the influence of condensate and trigger the atomizing unit 30 to work, resulting in aerosol loss and power loss, or even the phenomenon of condensate accumulating on the airflow sensor 20 and damaging the airflow sensor 20.

[0042] Furthermore, the airflow sensor 20 is located in the middle of the detection airway 12. That is, the airflow sensor 20 is not near the bottom of the detection airway 12, thus placing it closer to the second air outlet 121. This shortens the response distance of the airflow sensor 20 and improves its response speed. In addition, by placing the airflow sensor 20 in the middle of the detection airway 12, even if liquid enters the detection airway 12 from the second air inlet 114, it can be effectively prevented from flowing directly to the airflow sensor 20, thereby reducing the risk of the airflow sensor 20 automatically activating or even being damaged.

[0043] Further, please refer to Figure 2-4 As shown, the housing 10 is configured to have a mounting hole 13, and the airflow sensor 20 is disposed in the mounting hole 13. The periphery of the airflow sensor 20 is sealed to the hole wall of the mounting hole 13 to prevent airflow from flowing through the gap between the outside of the airflow sensor 20 and the hole wall, thus affecting the detection accuracy of the airflow sensor 20.

[0044] The detection airway 12 includes a detection hole 122 and a main airway 123. The main airway 123 connects the second air outlet 121 and the detection hole 122. The detection hole 122 connects the main airway 123 and the mounting hole 13. When the user is in a suction state, the airflow in the detection airway 12 will flow from the detection hole 122 through the main airway 123 and then out of the second air outlet 121. The airflow sensor 20 located in the mounting hole 13 sends a feedback signal to the control unit 40 when it detects that the airflow has passed through or that the negative pressure generated by suction has been generated.

[0045] Furthermore, the main air passage 123 has a blind end 124 opposite to the second air outlet 121. In use, the blind end 124 is located below the second air outlet 121, thus the blind end 124 is the bottom of the detection air passage 12. The detection hole 122 communicates with the side wall of the main air passage 123 and is spaced a certain distance from the blind end 124, so that the detection hole 122 is located between the blind end 124 and the second air outlet 121. Therefore, even if liquid enters the detection air passage 12 through the second air outlet 121, it will not flow directly from the detection hole 122 to the airflow sensor 20, thereby reducing the risk of the airflow sensor 20 automatically activating.

[0046] Furthermore, the aperture of the detection hole 122 is smaller than that of the mounting hole 13, which further reduces the risk of liquid flowing through the detection hole 122 to the airflow sensor 20, thereby effectively improving the protection of the airflow sensor 20 and reducing the possibility of the airflow sensor 20 being self-activated or even damaged.

[0047] Furthermore, the detection surface 21 of the airflow sensor 20 faces the detection hole 122, so that in the use state, and when the electronic atomizing device 100 is placed vertically (i.e., both the first air outlet 111 and the second air outlet 121 are facing upwards), the detection surface 21 does not face the second air outlet 121, thereby preventing liquid from covering the detection surface 21 and affecting the use of the airflow sensor 20.

[0048] Furthermore, in one embodiment, a liquid-locking element may be provided within the main air passage 123. This element is used to lock in liquid entering the detection air passage 12 from the second air outlet 121, thereby preventing the liquid from flowing into the airflow sensor 20. The liquid-locking element may be made of cotton material, which can both lock in the liquid and allow airflow to pass through, thus not affecting the detection of the airflow sensor 20. Preferably, the liquid-locking element is located within the main air passage 123.

[0049] In another embodiment, the main air passage 123 may also be provided with an adsorption structure. This adsorption structure is used to absorb liquid entering the detection air passage 12 from the second air outlet 121, thereby preventing the liquid entering the detection air passage 12 from flowing towards the airflow sensor 20. The adsorption structure may be an adsorption column protruding from the inner wall of the detection air passage 12, with a small spacing between adjacent adsorption columns. This makes it difficult for liquid on the inner wall of the detection air passage 12 to flow, thus adsorbing it onto the adsorption columns and the inner wall of the detection air passage 12, thereby intercepting the liquid and preventing it from impacting the airflow sensor 20.

[0050] Further, please refer to Figure 3-4 As shown, the atomizing airway 11 includes a mouthpiece section 112 and an atomizing section 113 that are interconnected. The end of the mouthpiece section 112 away from the atomizing section 113 is the first air outlet 111, and the atomizing unit 30 is disposed in the atomizing section 113. The housing 10 is also configured to form a liquid storage chamber 14, which is disposed on the outside or periphery of the atomizing airway 11, and the aerosol matrix contained in the liquid storage chamber 14 can flow to the atomizing unit 30 and be heated to generate aerosol.

[0051] The housing 10 is configured to have a suction nozzle 15, which comprises a suction nozzle section 112, a first air outlet 111, a main air passage 123, a detection hole 122, and a second air outlet 121. The main air passage 123 is arranged around the outer periphery of the suction nozzle section 112, thereby effectively increasing the space of the main air passage 123. This increases the surface area and volume of the detection air passage 12 on the corresponding inner wall portion of the main air passage 123, further reducing the risk of liquid flowing into the detection hole 122.

[0052] Furthermore, the detection hole 122 and the second air outlet 121 are located on the same side of the suction section 112, thereby further shortening the distance between the airflow sensor 20 and the second air outlet 121, which can further improve the efficiency of the airflow sensor 20.

[0053] Furthermore, the atomizing unit 30 is located within the atomizing section 113 and away from the nozzle section 112, so that in the suction state the atomizing unit 30 is close to the bottom of the liquid storage tank 14, so that the aerosol matrix in the liquid storage tank 14 can easily flow to the atomizing unit 30.

[0054] Please see Figure 3 As shown, the control unit 40 includes a first control board 41 and a second control board 42 electrically connected. The first control board 41 is disposed inside the housing 10 and located at the air inlet 114 of the atomizing airway 11. The air inlet 114 is opposite to the air outlet, and the atomizing unit 30 is electrically connected to the first control board 41, thereby shortening the electrical connection length between the atomizing unit 30 and the first control board 41. The second control board 42 is disposed outside the atomizing airway 11 and extends along the air inlet 114 toward the first air outlet 111, that is, the second control board 42 is closer to the detection airway 12 than the first control board 41. The airflow sensor 20 is electrically connected to the second control board 42, thereby shortening the length of the electrical connection line between the airflow sensor 20 and the second control board 42.

[0055] Further, please refer to Figure 2 As shown, the atomizing unit 30 includes an atomizing tube 31, a liquid-guiding cotton 32, and a heating element 33. The atomizing tube 31 defines the atomizing section 113. The liquid-guiding cotton 32 is disposed on the inner wall of the atomizing tube 31 and covers the liquid-guiding hole 311 of the atomizing tube 31 that connects to the liquid storage chamber 14. The heating element 33 is disposed on the inner wall of the liquid-guiding cotton 32. The aerosol matrix in the liquid storage chamber 14 moves through the liquid-guiding hole 311 to the liquid-guiding cotton 32 and is heated and atomized to generate aerosol when the heating element 33 is energized, and then released into the atomizing section 113.

[0056] Furthermore, the atomizing airway 11 further includes an air inlet section 115, which connects to the end of the atomizing section 113 away from the mouthpiece section 112, so that the atomizing section 113 connects between the air inlet section 115 and the mouthpiece section 112. The air inlet section 115 is configured to form the air inlet end 114.

[0057] Please see Figure 3-4 As shown, the electronic atomizing device 100 further includes a control switch 50 and an adjusting member 60. The control switch 50 is located on the side of the first control plate 41 away from the atomizing section 113. The adjusting member 60 includes an operating part 61, an air regulating plate part 62, and a trigger part 63. The air regulating plate part 62 is located on the side of the first control plate 41 away from the atomizing section 113. The trigger part 63 is located on the side of the air regulating plate part 62 facing the first control plate 41 and is connected to the control switch 50. The operating part 61 is located on the air regulating plate part 62 and, under the drive of an external force, drives the air regulating plate part 62 and the trigger part 63 to move synchronously, so that the adjusting member 60 has a first position and a second position relative to the housing 10.

[0058] When the adjusting member 60 is in the first position, the control switch 50 is in the closed state, and the air regulating plate 62 blocks the air inlet end 114; when the adjusting member 60 is in the second position, the control switch 50 is in the open state, and the air regulating plate 62 opens the air inlet section 115.

[0059] Furthermore, the air regulating plate 62 has a first air inlet 621 and a second air inlet 622, and the diameters of the first air inlet 621 and the second air inlet 622 are different.

[0060] Please see Figure 5As shown, the adjusting member 60 also has a third position, which is different from the first and second positions. When the adjusting member 60 is in the first position, the control switch 50 is in the closed state, and the air regulating plate 62 blocks the air inlet end 114; when the adjusting member 60 is in the second position, the control switch 50 is in the open state, and the air regulating plate 62 connects the air inlet section 115 to the outside through the first air inlet hole 621; when the adjusting member 60 is in the third position, the control switch 50 is in the open state, and the adjusting plate connects the air inlet section 115 to the outside through the second air inlet hole 622.

[0061] Furthermore, the housing 10 includes an outer shell 16 and a mounting base 17. The outer shell 16 and the mounting base 17 are sealed together to define the liquid storage chamber 14 and the buffer chamber 18. The buffer chamber 18 is connected to the liquid guiding hole 311. The mounting base 17 is also configured to have a liquid passage hole 171, which is connected between the liquid storage chamber 14 and the buffer chamber 18, so that the aerosol matrix in the liquid storage chamber 14 flows sequentially through the liquid passage hole 171, the buffer chamber 18 and the liquid guiding hole 311 to the liquid guiding cotton 32.

[0062] Further, please refer to Figure 2-5 As shown, the electronic atomizing device 100 also includes a control component 70, which is movably disposed at the liquid passage 171 and has a blocked position and a connected position. When the control component 70 is in the blocked position, the liquid passage 171 is blocked, thereby isolating the liquid storage chamber 14 from the buffer chamber 18, and the aerosol matrix in the liquid storage chamber 14 cannot move to the buffer chamber 18. When the control component 70 is in the connected position, the liquid passage 171 connects the liquid storage chamber 14 and the buffer chamber 18, and the aerosol matrix in the liquid storage chamber 14 can move to the buffer chamber 18 through the liquid passage 171.

[0063] Furthermore, the control component 70 includes a blocking member 71, a pushing member 72, and an elastic member 73. The blocking member 71 is connected to the pushing member 72, and the elastic member 73 is used to drive the pushing member 72 to move the blocking member 71 synchronously, so that the control component 70 is kept in the conducting position.

[0064] When the adjusting member 60 is in the first position, the electronic atomizing device 100 is in the off state, and the external airflow cannot enter the atomizing air passage 11 through the air inlet 114. At the same time, the air regulating plate 62 also supports the pushing member 72 to overcome the force of the elastic member 73 and drive the sealing member 71 to block the liquid passage 171, so that the aerosol matrix in the liquid storage chamber 14 cannot move to the buffer chamber 18.

[0065] When the adjusting member 60 is in the second position or the third position, the electronic atomizing device 100 is in the powered-on state, and the external airflow can pass through the first air inlet 621 or the second air inlet 622 to reach the air inlet end 114 and enter the atomizing air passage 11. At the same time, the air regulating plate 62 releases the pushing member 72 so that the pushing member 72, driven by the elastic member 73, opens the liquid passage 171, thereby allowing the aerosol matrix in the liquid storage chamber 14 to move towards the buffer chamber 18.

[0066] Furthermore, the outer shell 16 is also provided with a liquid injection hole 161, which is connected to the liquid storage chamber 14 and is used to replenish the liquid storage chamber 14 with aerosol matrix. The electronic atomizing device 100 also includes a liquid injection plug 80, which is used to block the liquid injection hole 161.

[0067] Furthermore, the control unit 40 also includes a battery 43, which is disposed inside the housing 16 and electrically connected to the first control board 41. The battery 43 is used to supply power to electrical components such as the first control board 41, the second control board 42, the control switch 50, and the heating element 33.

[0068] 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.

[0069] 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.

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.
