Description

Technical Field

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

[0002] The microphone in the electronic atomizer device determines whether it is in the smoking state by detecting the movement of the airflow, and then controls the working state of the electronic atomizer device. The sealing structure of the microphone part in the existing electronic atomizer device is usually achieved by the sealing rib on the silicone side of the microphone and the interference fit of the microphone. Although this sealing structure is effective for the structural sealing of a single microphone, it is invalid for the microphone integrated on the circuit board, because there is a gap between the microphone integrated on the circuit board and the circuit board, and the gap between the microphone and the circuit board cannot be sealed only by the sealing rib on the silicone side of the microphone and the interference fit of the microphone. Therefore, part of the airflow will enter from the gap, affecting the detection of the airflow by the microphone, thereby affecting the smoking experience of the electronic atomizer device.

[0035] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] like Figure 1-Figure 2 As shown, the electronic atomization device 100 includes a housing 2, a circuit board 3, a battery 4, an atomization core 5 and a liquid storage assembly 6. The battery 4, the circuit board 3 and the atomization core 5 are installed on the housing 2, and the battery 4, the circuit board 3 and the atomization core 5 are electrically connected.

[0037] It is understandable that the liquid storage component 6 can be installed in the housing 2 before use, or installed in the housing 2 during use, and this is not limited here. The liquid storage component 6 stores a liquid matrix, and the atomizing core 5 is used to heat the liquid matrix to generate an aerosol. The battery 4 supplies power to the atomizing core 5, so that the atomizing core 5 heats the liquid matrix in the liquid storage component 6 to form an aerosol.

[0038] The atomizing core 5 can be arranged in the housing 2 or in the liquid storage assembly 6. Figure 2 As shown, the atomizer core 5 is disposed in the housing 2. The atomizer core 5 can receive the electric power of the battery 4 to heat the liquid matrix in the liquid storage component 6 to form an aerosol.

[0039] In other optional embodiments, the atomizer core 5 can also be integrated in the liquid storage assembly 6, and an atomizer core 5 is arranged in each liquid storage assembly 6. When the liquid storage assembly 6 is installed in the housing 2, the atomizer core 5 can be electrically connected to the battery 4, so that the battery 4 can power the atomizer core 5.

[0040] like Figure 8As shown, the atomizer core 5 of the embodiment of the present application includes a heating element 51, a liquid guide element 52, an electrode lead 53, a tubular element 54 and a fixing element 55. The tubular element 54 is fixedly installed in the housing 2, and the tubular element 54 is arranged in the longitudinal direction. A liquid inlet hole 541 is arranged on the side wall of the tubular element 54, and the liquid matrix in the liquid storage assembly 6 enters the tubular element 54 through the liquid inlet hole 541. The liquid guide element 52 is arranged in the tubular element 54, and the outer surface of the liquid guide element 52 covers the liquid inlet hole 541, so as to receive the liquid matrix entering the tubular element 54 through the liquid inlet hole 541. The heating element 51 is attached to the inner side of the liquid guide element 52, and the heating element 51 is used to heat the liquid matrix to generate an aerosol. One end of the electrode lead 53 is connected to the heating element 51, and the other end is connected to the battery 4; the number of electrode leads 53 is at least two. The fixing element 55 is at least partially accommodated in the tubular element 54, and is used to cooperate with the inner wall of the tubular element 54 to fix the electrode lead 53.

[0041] like Figure 7 As shown, the liquid storage component 6 includes a shell 61, a first seal 62, a second seal 63 and a liquid storage cotton 64. The shell 61 is cylindrical, and the liquid storage cotton 64 is arranged in the shell 61, and the liquid storage cotton 64 carries a liquid matrix. The first seal 62 and the second seal 63 are respectively covered at both ends of the shell 61 in the longitudinal direction, so that the liquid storage cotton 64 is fixed in the shell 61. The first seal 62, the second seal 63 and the liquid storage cotton 64 are correspondingly provided with holes, thereby forming an air flow channel 65 of the liquid storage component 6. The tubular element 54 is assembled into the air flow channel 65 of the liquid storage component 6, so that the liquid matrix in the liquid storage cotton 64 can enter the liquid guide element 52 through the liquid inlet hole 541 on the tubular element 54, so as to be heated and atomized by the heating element 51. The above-mentioned structural design of the liquid storage component 6 is convenient for cooperation with the atomization core 5, so as to realize convenient and quick disassembly and assembly.

[0042] like Figure 2-Figure 6 As shown, in some embodiments, the electronic atomization device 100 also includes a microphone 31 and a microphone seal 7, the microphone 31 is arranged on the circuit board 3; the microphone seal 7 is provided with a first accommodating cavity 71, and the microphone 31 is at least partially accommodated in the first accommodating cavity 71; wherein, the end of the microphone seal 7 facing the circuit board 3 has a protruding first sealing rib 72, and the first sealing rib 72 abuts against the circuit board 3 to prevent external air from flowing in through the gap between one end of the microphone seal 7 and the circuit board 3; the end of the microphone seal 7 facing away from the circuit board 3 is provided with a first opening 73, so that the microphone 31 can sense changes in external air through the first opening 73.

[0043] The microphone seal 7 is provided with a first sealing rib 72, which is elastically deformed when the first sealing rib 72 abuts against the circuit board 3, so that the gap between the microphone 31 and the circuit board 3 is sealed, so that the airflow can no longer enter from the gap, and further can not affect the detection of the airflow by the microphone 31 through the first opening, thereby ensuring the suction experience of the electronic atomization device 100.

[0044] Specifically, when the user inhales, air will enter the housing 2 from the outside to form an airflow. Since the microphone 31 is at least partially contained in the microphone seal 7, and the microphone seal 7 is in contact with the circuit board 3 through the first sealing rib 72 to form a seal, the air in the first accommodating chamber 71 can only flow out of the first accommodating chamber 71 through the first opening 73 under the drive of the airflow, so that the microphone 31 at least partially contained in the first accommodating chamber 71 can detect the movement of the airflow through the first opening 73. Since the air in the first accommodating chamber 71 flows out during inhalation, the first accommodating chamber 71 is in a negative pressure state. Therefore, after the user stops inhaling, the air outside the first accommodating chamber 71 will be replenished into the first accommodating chamber 71 to balance the air pressure of the first accommodating chamber 71. At this time, the microphone 31 can detect the movement of the airflow.

[0045] The microphone 31 is integrated in the circuit board 3 and electrically connected to the controller integrated in the circuit board 3. The controller collects and judges the detection signal fed back by the microphone 31, so as to control the start and stop of the heating element 51 according to the judgment result.

[0046] The first sealing rib 72 is in contact with the circuit board 3 to elastically deform to seal the first accommodating cavity 71. The cross-sectional shape of the first sealing rib 72 can be square, rectangular, triangular, rhombus, circular or elliptical. In one example, the first sealing rib 72 is an annular structure arranged around the microphone 31, and one end of the first sealing rib 72 close to the circuit board 3 is inclined toward the center, which is conducive to contacting the circuit board 3 to elastically deform to complete the sealing of the first accommodating cavity 71.

[0047] Specifically, Figure 2-Figure 6 As shown, a second accommodating cavity 621 is defined between the first sealing member 62 and the circuit board 3 , the microphone sealing member 7 is at least partially accommodated in the second accommodating cavity 621 , the first sealing member 62 is provided with a second opening 622 in the second accommodating cavity 621 , and the second opening 622 is communicated with the first opening 73 .

[0048] Since the microphone seal 7 is accommodated in the second accommodating chamber 621 defined between the first seal 62 and the circuit board 3, in order to enable the microphone 31 accommodated in the microphone seal 7 to receive the airflow outside the second accommodating chamber 621, the first seal 62 is provided with a second opening 622 in the second accommodating chamber 621 that is connected with the first opening 73, so that the airflow can flow to the first opening 73 through the second opening 622 and finally enter the first accommodating chamber 71 for detection by the microphone 31.

[0049] like Figure 2-Figure 6 As shown, in some embodiments, a third accommodating cavity 623 is further defined between the first sealing member 62 and the circuit board 3 , the first sealing member 62 is provided with a partition portion 624 , the partition portion 624 separates the second accommodating cavity 621 and the third accommodating cavity 623 , and the second opening 622 is provided in the partition portion 624 .

[0050] Specifically, the housing 2 is provided with a fourth accommodating chamber 21 and an air inlet 22. The circuit board 3, the first sealing member 62, the battery 4 and the atomizer core 5 are accommodated in the fourth accommodating chamber 21. The air inlet 22 connects the fourth accommodating chamber 21 with the outside.

[0051] The circuit board 3 is provided with a first vent hole 33 along the thickness direction, and the first vent hole 33 communicates with the third accommodating cavity 623 and the air inlet 22 .

[0052] More specifically, the housing 2 is provided with an air outlet 23 ; the first sealing member 62 is provided with a second air vent 625 along the thickness direction, and the second air vent 625 is connected to the third accommodating cavity 623 ; the air flow channel 65 provided in the liquid storage assembly 6 is connected to the second air vent 625 and the air outlet 23 .

[0053] The air inlet 22 , the first air hole 33 , the second air hole 625 , the air flow channel 65 and the air outlet 23 are interconnected to form an air path structure for air flow to flow through.

[0054] When the user inhales, when the airflow passes through the third accommodating chamber 623 and enters the second vent hole 625, the air in the second accommodating chamber 621 is driven by the airflow, so that the first opening 73 and the second opening 622 flow out to join the airflow, so that the second accommodating chamber 621 is under negative pressure. The microphone 31 detects the movement of the airflow and feeds back to the controller, and the controller controls the atomizer core 5 to heat. Since the temperature of the atomizer core 5 is relatively high during operation, the airflow flows into the third accommodating chamber 623 from the air inlet 22 and the first vent hole 33 and enters the airflow channel 65 to mix with the aerosol, and condensed water may be formed on the inner wall of the airflow channel 65 above the atomizer core 5. The condensed water then slides down the inner wall of the air flow channel 65 and finally falls on the circuit board 3 through the second vent hole 625. Therefore, a partition portion 624 is provided on the first sealing member 62. The partition portion 624 separates the second accommodating chamber 621 and the third accommodating chamber 623, so that the condensed water stays in the third accommodating chamber 623 and does not flow to the microphone 31 accommodated in the second accommodating chamber 621.

[0055] like Figure 2As shown, in some embodiments, the electronic atomization device 100 further includes an adsorbent 8, which is accommodated in the third accommodation cavity 623 and is used to absorb liquid. After the liquid slides down, it will be absorbed by the adsorbent 8 and will not drip onto the circuit board 3, thereby preventing the electronic components on the circuit board 3 from contacting the liquid, thereby ensuring the reliability of the electronic atomization device 100.

[0056] Because in some embodiments, the opening area of ​​the second opening 622 is larger than the opening area of ​​the first opening 73, when the first opening 73 is connected to the second opening 622, part of the airflow will flow into or out of the gap between the first sealing member 62 and the microphone seal 7 from the second opening 622, thereby affecting the detection of the airflow by the microphone 31. Figure 2-Figure 6 As shown, the microphone seal 7 of the present application is provided with a blocking portion 74 , which blocks a portion of the second opening 622 , so that the blocking portion 74 seals the portion of the second opening 622 whose area is larger than that of the first opening 73 .

[0057] Specifically, Figure 6 As shown, in some embodiments, the second opening 622 includes a trapezoidal area 6221 and a square area 6222, the shape of the blocking portion 74 is correspondingly a trapezoid, the trapezoidal blocking portion 74 is adapted to the size of the trapezoidal area 6221 of the second opening 622, and the square area 6222 of the second opening 622 corresponds to the first opening 73. The shape of the second opening 622 is set to be a combination of a trapezoid and a square, and when the first seal 62 and the microphone seal 7 are assembled, the trapezoidal area 6221 of the second opening 622 can guide the trapezoidal blocking portion 74 to complete the assembly of the microphone seal 7 and the first seal 62.

[0058] Since the microphone seal 7 is accommodated in the second accommodating chamber 621, when the microphone seal 7 and the first seal 62 are assembled, in order to ensure that the microphone seal 7 can be installed in the preset position of the second accommodating chamber 621, Figure 4-Figure 6 As shown, in some embodiments, a limiting portion 75 is provided on the circumferential side of the microphone seal 7, and a limiting groove 626 is provided on the first seal 62. The limiting portion 75 cooperates with the limiting groove 626 to limit the longitudinal movement of the microphone seal 7 in the first seal 62. At the same time, since the microphone seal 7 is clamped by the first seal 62 and the circuit board 3, the first sealing rib 72 undergoes elastic deformation. Therefore, the cooperation between the limiting portion 75 and the limiting groove 626 can also provide a force for the elastic deformation of the first sealing rib 72 under the clamping of the first seal 62 and the circuit board 3, thereby preventing the microphone 31 accommodated in the first accommodating cavity 71 from being squeezed.

[0059] Preferably, the limiting portion 75 is arranged on a peripheral area of ​​the microphone seal 7 close to the circuit board 3 , and the limiting groove 626 is arranged on a side of the first seal 62 facing the circuit board 3 .

[0060] like Figure 5 As shown, in an optional embodiment, an annular sealing portion 76 is provided at one end of the microphone seal 7 facing the first seal 62, the first opening 73 is provided at the annular sealing portion 76, one end of the annular sealing portion 76 abuts the first seal 62, and the other end of the annular sealing portion 76 partially abuts the microphone 31.

[0061] Since one end of the annular sealing portion 76 abuts against the first sealing member 62 and the other end partially abuts against the microphone 31, a seal is formed, and airflow flowing in or out of the first opening 73 provided in the annular sealing portion 76 can directly act on the microphone 31, so that the controller of the circuit board 3 can well control the start and stop of the electronic atomization device 100 by detecting the movement of the airflow through the microphone 31.

[0062] like Figure 4-Figure 6 As shown, in an optional embodiment, a second sealing rib 77 is provided on the circumferential side of the microphone seal 7 , and the second sealing rib 77 is interference fit with the first sealing 62 .

[0063] The interference fit between the second sealing rib 77 and the first sealing member 62 can enhance the sealing performance between the microphone seal 7 and the first sealing rib 72 .

[0064] It should be noted that a plurality of second sealing ribs 77 may be provided, and the cross-sectional shape of the second sealing rib 77 may be square, rectangular, triangular, diamond, circular, elliptical, or the like.

[0065] like Figure 2-Figure 6 As shown, in an electronic atomization device, the end of the first sealing member 62 facing the circuit board 3 has a protruding third sealing rib 627, and the third sealing rib 627 abuts against the circuit board 3 to prevent the air in the second accommodating cavity 621 from flowing out through the gap between one end of the first sealing member 62 and the circuit board 3.

[0066] The third sealing rib 627 elastically deforms when it abuts against the circuit board 3, thereby ensuring the sealing of the second accommodating chamber 621 and the third accommodating chamber 623, thereby maintaining the sealing of the air path structure, avoiding air leakage of the electronic atomization device 100, and ensuring that the suction resistance meets the design requirements, thereby improving the user's suction experience.

[0067] It should be noted that the third sealing rib 627 is in contact with the circuit board 3 to elastically deform to complete the sealing of the second accommodating cavity 621 and the third accommodating cavity 623, so the cross-sectional shape of the third sealing rib 627 can be square, rectangular, triangular, diamond, circular or elliptical. Similar to the first sealing rib 72, the third sealing rib 627 is configured as an annular structure, and the end of the third sealing rib 627 close to the circuit board 3 is inclined toward the center.

[0068] like Figure 2 As shown, in some embodiments, a charging interface 32 is further provided on the circuit board 3, and the charging interface 32 is exposed on the housing 2. At the same time, except for the microphone 31, no electronic components are welded on the surface of the circuit board 3 facing the second vent hole 625, and the remaining electronic components are welded on the surface of the circuit board 3 facing away from the second vent hole 625. The above arrangement ensures that even if the adsorbent 8 fails to completely adsorb the condensate, the condensate will not directly contact the electronic components on the circuit board 3 when it drips, thereby avoiding damage to the electronic components.

[0069] like Fig. 9 As shown, in some embodiments, a sound announcer 91 and a display screen 92 are also provided on the circuit board 3. When in use, the sound announcer 91 cooperates with the display screen 92 to provide a power on / off animation and sound interaction design, and voice broadcasts some UIs (such as low oil, low electricity, power switching, related alarms, etc.) to give users a more intuitive experience.

[0070] It should be noted that the sound announcer 91 may be a speaker, and the display screen 92 may be a TFT screen or a digital screen.

[0071] The above are only preferred embodiments of the present invention and do not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
