Description

Technical Field

[0001] This utility model relates to the field of atomization technology, and in particular to an atomization device. Background Technology

[0002] Atomizing devices are typically equipped with a microphone. The microphone is connected to the atomizing chamber and the outside of the atomizing device through different air passages on both sides. The microphone is also electrically connected to the circuit board. When the user inhales from the atomizing device, a negative pressure is generated in the atomizing chamber, causing the conductive film in the microphone to deform. This causes a change in the microphone's capacitance, which in turn causes the circuit board to control the battery to supply power to the atomizing core in the atomizing chamber. This causes the liquid adsorbed on the atomizing core to be converted into a mist for the user to inhale.

[0003] However, the installation method of the microphone and circuit board in existing atomizing devices is not reasonable, which makes the internal space occupied by the microphone and circuit board large, resulting in a less compact internal structure of the atomizing device and hindering the miniaturization of the atomizing device.

[0038] The following will mainly describe the specific structure of the atomizing device.

[0039] Reference Figures 1 to 9 In this embodiment of the utility model, the atomizing device includes:

[0040] The outer casing 100 has an open lower end;

[0041] The bottom cover 200 is installed at the lower end of the outer shell 100 to form a receiving cavity with the outer shell 100. The bottom cover 200 has a microphone air inlet 210 and an atomizing air inlet 220.

[0042] The mounting bracket 300 is installed in the receiving cavity, with the battery 310 installed on its upper part and the mounting cavity 330 formed on its lower part. An air intake channel 320 communicating with the atomizing cavity of the atomizing device is formed between the mounting bracket 300, the battery 310 and the outer shell 100.

[0043] A sealing element 400 is installed in the mounting cavity 330 and its bottom abuts against the bottom cover 200. The sealing element 400 forms a first air passage 410 that communicates with the microphone air inlet 210. The sealing element 400 and the mounting bracket 300 also form a second air passage 420 that communicates with the atomizing air inlet 220 and the air inlet channel 320 respectively.

[0044] The circuit board 500 and the microphone 610 are both installed in the mounting cavity 330. The circuit board 500 abuts against the upper end of the sealing member 400. The circuit board 500 is provided with an air passage 510 that passes through its upper and lower sides to communicate with the first air passage 410. The microphone 610 is installed on the upper side of the circuit board 500. An air passage gap 511 is formed between the lower end of the microphone 610 and the circuit board 500, which communicates with the air passage 510. The upper end communicates with the air inlet channel 320.

[0045] Specifically, in this embodiment, the upper side of the microphone 610 is connected to the air intake channel 320 inside the mounting bracket 300, and the air intake channel 320 is connected to the atomizing chamber of the atomizing device, so that the upper side of the microphone 610 can ultimately connect to the atomizing chamber, while the lower side of the microphone 610 is connected to the outside of the atomizing device through the air gap 511, the first air passage 410, and the microphone air inlet 210. Regarding the air intake path of the atomizing chamber, external gas can flow into the atomizing chamber in sequence through the atomizing air inlet 220, the second air passage 420, and the air intake channel 320. When the user inhales the atomizing device, the atomizing chamber generates a negative pressure, causing the conductive film of the microphone 610 to deform, thereby causing a change in the capacitance of the microphone 610. This causes the circuit board 500 to control the battery 310 to supply power to the atomizing core of the atomizing chamber, so that the liquid adsorbed on the atomizing core is converted into aerosol for the user to inhale.

[0046] Since both the circuit board 500 and the microphone 610 are installed within the mounting cavity 330 of the mounting bracket 300, and the microphone 610 and the seal 400 are located on the upper and lower sides of the circuit board 500 respectively, the mounting bracket 300 is utilized for both installation and space, resulting in a neat and compact internal structure for the atomizing device. Furthermore, because the seal 400 is also installed within the mounting cavity 330, it ensures the sealing effect of the first airway 410 and the second airway 420 without taking up additional space, thus making the atomizing device more compact.

[0047] In some embodiments, the outer wall of the mounting cavity 330 forms a recessed platform 303, which faces the battery 310. The air inlet of the second air passage 420, located away from the atomizing air inlet 220, is situated at the bottom of the recessed platform 303. This increases the distance between the air inlet of the second air passage 420 and the battery 310, allowing for greater flow space after the gas exits the second air passage 420. This effectively avoids obstruction of airflow by the battery 310, improves the smoothness of airflow, and ensures that the gas can quickly and smoothly flow into the atomizing chamber of the atomizing device.

[0048] It is understandable that the cross-sectional area of ​​the microphone 610 is smaller than the cross-sectional area of ​​the circuit board 500. To improve the compactness of the internal structure of the mounting cavity 330, in some embodiments, the lower part of the mounting bracket 300 includes a connected first part 301 and a second part 302. The cross-section of the second part 302 is larger than the cross-section of the first part 301, so that the recessed platform 303 is formed between the first part 301 and the second part 302. The first part 301 forms a first cavity segment, and the second part 302 forms a second cavity segment connected to the first cavity segment. The cross-sectional area of ​​the second cavity segment is larger than the cross-sectional area of ​​the first cavity segment. The circuit board 500 and the seal 400 are located in the second cavity segment, and the microphone 610 is partially located in the first cavity segment. That is, the mounting cavity 330 is narrower at the top and wider at the bottom, which accommodates the dimensions of the microphone 610, the circuit board 500, and the seal 400. In this way, while forming the recessed platform 303 on the outer wall of the mounting cavity 330 to facilitate airflow, it also improves the compactness of the internal structure of the mounting cavity 330.

[0049] In some embodiments, the lower end of the seal 400 is provided with a insertion hole 421 communicating with the atomizing air inlet 220, the circuit board 500 is provided with through holes 540 penetrating its upper and lower sides, and the cavity wall of the mounting cavity 330 forms an air intake column 331. The air intake column 331 passes through the through hole 540, and its lower end is inserted into the insertion hole 421. The air intake column 331 is provided with air intake chambers penetrating its two ends. Since the air intake column 331 of the mounting bracket 300 passes through the through hole 540 of the circuit board 500, the circuit board 500 is confined within the mounting bracket 300, improving the stability of the circuit board 500 installation. Similarly, the air intake column 331 is inserted into the insertion hole 421 of the seal 400, confining the seal 400 within the mounting bracket 300, improving the stability of the seal 400 installation. Furthermore, the sealing function of the seal 400 is utilized effectively to improve the sealing performance of the second air passage 420 and ensure the air intake effect.

[0050] In some embodiments, the bottom cover 200 also has an opening 230, and the sealing member 400 forms an insertion cavity 430 that extends through its upper and lower ends and communicates with the opening 230. A charging connector 520 is provided on the lower side of the circuit board 500, and the charging connector 520 is inserted into the insertion cavity 430. That is, the charging connector 520 is also located inside the mounting cavity 330, and does not occupy additional space, further improving the compactness of the internal structure of the atomizing device and making the atomizing device smaller.

[0051] Regarding the mounting method of the circuit board 500, in some embodiments, the circuit board 500 has protruding locking protrusions 530 on opposite sides, and the mounting cavity 330 has locking holes 334 on both sides, with the locking protrusions 530 engaging with the locking holes 334. This allows for easy assembly and disassembly without the need for additional tools. Specifically, the mounting cavity 330 has a notch 332 in its cavity wall, and an elastic arm 333 protrudes from the inner wall of the notch 332. The elastic arm 333 has the locking holes 334. This facilitates the deformation of the elastic arm 333, allowing the locking protrusions 530 to extend into or retract from the locking holes 334, thus facilitating the assembly and disassembly of the circuit board 500.

[0052] In some embodiments, the atomizing device further includes a sealing silicone 620 sleeved on the microphone 610. The sealing silicone 620 has two connected ends, and its outer wall abuts against the inner wall of the mounting cavity 330. The outer wall of the sealing silicone 620 has a circumferentially extending limiting recess. The cavity wall of the mounting cavity 330 has a circumferentially extending limiting protrusion 335 protruding from it, and the limiting protrusion 335 is inserted into the limiting recess. The sealing silicone 620 is used to seal the microphone 610, ensuring that the airflow on the upper and lower sides of the microphone 610 is not interconnected, thereby improving the sensitivity of the microphone 610 in sensing airflow.

[0053] In some embodiments, the mounting bracket 300 is provided with a first limiting block 341 and a second limiting block 342 at the upper and lower ends corresponding to the battery 310, respectively, and the battery 310 is sandwiched between the first limiting block 341 and the second limiting block 342. This improves the installation stability of the battery 310, ensuring its normal use, while also ensuring the stability of the air intake channel 320 formed between the battery 310, the mounting bracket 300, and the outer casing 100, thereby guaranteeing the air intake effect.

[0054] In some embodiments, the upper end wall of the seal 400 is provided with a receiving hole 440, which is used to receive components on the circuit board 500. That is, the receiving hole 440 of the seal 400 can avoid the components, so that the seal 400 will not affect the components on the circuit board 500.

[0055] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
