The liquid storage chamber is connected to the atomizing cavity through the liquid flow channel. The atomizing core is usually located inside the atomizing cavity. The atomizing core is used to heat the atomizing liquid entering the atomizing cavity to generate an aerosol. The airflow entering the atomizing cavity through the airflow channel mixes with the aerosol and is then discharged from the atomizing channel.

[0003] Atomizing devices are typically equipped with a pressure sensor. The control module in the atomizing device can control the heating or stopping of the atomizing core based on the pressure detection result of the pressure sensor in the airflow channel.

Detailed Implementation

[0023] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0024] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0025] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0026] This application discloses an atomizing device; please refer to the embodiments therein. Figures 1 to 3 The atomizing device includes a main body 100 and a pressure sensor 7 installed on the main body 100. The main body 100 has a liquid storage chamber 38, an air inlet channel 361, a connecting channel 352, an atomizing chamber 39, an atomizing channel 311, and a sensing air channel 362. The main body 100 includes an atomizing core 33 installed in the atomizing chamber 39. The liquid storage chamber 38 is connected to the atomizing chamber 39 through a liquid flow channel. The atomizing core 33 can heat the atomizing liquid in the atomizing chamber 39 to generate aerosol. The atomizing channel 311 is connected to the atomizing chamber 39 and is used to discharge the aerosol generated in the atomizing chamber 39.

[0027] The air intake channel 361 is connected to the atomizing chamber 39 via the connecting channel 352, and air can be supplied to the atomizing chamber 39 through the air intake channel 361 and the connecting channel 352. For some embodiments, please refer to... Figure 2 The connecting channel 352 and the atomizing channel 311 are arranged on both sides of the atomizing chamber 39 in a first direction. This first direction can be the up and down direction when the atomizing device is in use. Both the connecting channel 352 and the atomizing channel 311 can be extended in the first direction to shorten the airflow path.

[0028] The air pressure sensor 7 is connected to the sensing airway 362, which has an opening 3621 that connects to the air intake channel 361. During the atomization process, the air pressure sensor 7 can detect the air pressure inside the air intake channel 361. The atomization device also includes a control module 6, which can control the operation of the atomizing core 33 based on the detection results of the air pressure sensor 7. For example, when there is a negative pressure in the air intake channel 361, the control module 6 can control the atomizing core 33 to heat up to generate aerosol for the user. Alternatively, when the air pressure inside the air intake channel 361 is equal to the external atmospheric pressure, the control module 6 can control the atomizing core 33 not to heat up, thereby achieving automatic control of the atomizing core 33, avoiding long-term dry burning of the atomizing core 33, and helping to extend the service life of the atomizing core 33.

[0029] Please refer to Figure 2 and Figure 3 The connecting channel 352 is located between the air intake channel 361 and the atomizing chamber 39 in the first direction. The channel wall of the connecting channel 352 includes a first channel wall 353 protruding into the air intake channel 361 in the first direction. The first channel wall 353 is staggered from the opening 3621 of the sensing air passage 362 in the plane perpendicular to the first direction. The first channel wall 353 can collect droplets of atomized liquid or condensate that enter the air intake channel 361 from the atomizing chamber 39 under the action of gravity, and allow the droplets to drip directly into the air intake channel 361 under the action of gravity. This can reduce the probability of atomized liquid or condensate entering the sensing air passage 362 along the channel wall of the air intake channel 361, thereby reducing the probability of atomized liquid or condensate seeping into the air pressure sensor 7 and improving the safety performance of the atomizing device.

[0030] In some embodiments, please refer to Figure 2 and Figure 3 The atomizing device also includes an atomizing component 3, which is arranged with the control module 6 in a first direction. The atomizing component 3 has a liquid storage chamber 38 and an atomizing chamber 39 arranged in the first direction. The atomizing component 3 includes an atomizing housing 31, an atomizing bracket 32, and a support frame 35. The atomizing bracket 32 ​​is sealed and installed inside the atomizing housing 31 and forms the liquid storage chamber 38 with the atomizing housing 31. The atomizing channel 311 is located on the atomizing housing 31, and the liquid storage chamber 38 is arranged around the atomizing channel 311. The atomizing housing 31 has an opening facing the control module 6. The support frame 35 is sealed and installed at the opening of the atomizing housing 31. The support frame 35 can be connected to the atomizing bracket 32 ​​through a snap-fit ​​structure. The support frame 35 can also be connected to the atomizing housing 31 through a snap-fit ​​structure, so as to achieve relative fixation of the atomizing housing 31, the atomizing bracket 32 ​​and the support frame 35. The atomizing housing 31, the support frame 35 and the atomizing bracket 32 ​​enclose and form the atomizing chamber 39. The liquid flow channel connecting the liquid storage chamber 38 and the atomizing chamber 39 is located on the atomizing bracket 32.

[0031] The support frame 35 has a mounting groove 351, the opening of which is positioned away from the atomizing chamber 39 in a first direction. The atomizing assembly 3 also includes a sealing element 36, which is located within the mounting groove 351 and seals against the side wall of the groove. The control module 6 includes a circuit board 61 and electronic components mounted on the circuit board 61. The surface of the circuit board 61 is perpendicular to the first direction. A pressure sensor 7 is mounted on the side of the circuit board 61 facing the atomizing chamber 39. The sealing element 36 is fitted onto the pressure sensor 7 and seals against it. The air intake channel 361 and the sensing air channel 362 are both located on the sealing element 36. The connecting channel 352 is located on the support frame 35. The circuit board 61 has an air intake hole that communicates with the air intake channel 361. External air entering the atomizing device can enter the air intake channel 361 through the air intake hole and then enter the atomizing chamber 39 along the connecting channel 352.

[0032] In some embodiments, please continue to refer to Figure 2 The intake channel 361 is connected to the connecting channel 352 in the first direction. The sensing channel 362 and the intake channel 361 are arranged in a plane perpendicular to the first direction. Both the intake channel 361 and the sensing channel 362 can be extended in the first direction to shorten the intake path and improve the sensitivity of the air pressure sensor 7.

[0033] In some embodiments, please continue to refer to Figure 2 For the first channel wall 353 protruding into the air intake channel 361 in the first direction, the first channel wall 353 has a first end face 3531. The first end face 3531 is located at the end of the first channel wall 353 away from the atomizing chamber 39 in the first direction. The first end face 3531 is arranged towards the air intake channel 361 in the first direction, and the first end face 3531 can be perpendicular to the first direction or can also form an angle of less than 90° with the first direction. The first end face 3531 is connected to the inner wall surface 3 of the channel wall of the connecting channel 352. The surfaces 533 can be smoothly connected by an outwardly convex curved surface 3532 to avoid forming sharp edges or corners between the first end face 3531 and the inner wall surface 3533. The outwardly convex curved surface 3532 can be an arc surface, which can guide the condensate or atomized liquid on the inner wall surface 3533 of the connecting channel 352 to the first end face 3531, so as to realize the accumulation of droplets on the first end face 3531. In addition, it can also prevent the airflow from forming a large-angle bending path between the first end face 3531 and the inner wall surface 3533, which helps to reduce airflow noise.

[0034] In some embodiments, please continue to refer to Figure 2Alternatively, the first end face 3531 and the inner wall surface 3533 of the connecting channel 352 can be connected by a chamfered surface. The chamfered surface can also guide the condensate or atomized liquid to flow to the first end face 3531, and the chamfered surface can help reduce the airflow noise at the location of the connecting channel 352.

[0035] In some embodiments, please continue to refer to Figure 2 To further reduce the probability of condensate or atomized liquid entering the sensing airway 362, the opening 3621 on the sensing airway 362, which communicates with the air inlet channel 361, is located on the side of the first end face 3531 facing the atomizing chamber 39 in the first direction. This reduces the probability of liquid accumulated on the first end face 3531 entering the sensing airway 362 through the opening 3621 during the shaking of the atomizing device. Of course, in some embodiments, the longer the distance between the first end face 3531 and the opening 3621 of the sensing airway 362 in the first direction, the lower the probability of liquid accumulated on the first end face 3531 entering the sensing airway 362, which means a higher safety level and safety performance of the atomizing device.

[0036] Alternatively, in other embodiments, it is also possible to provide the first end face 3531 to correspond to the opening 3621 on the sensing airway 362 in the first direction, or to provide the first end face 3531 between the opening 3621 of the sensing airway 362 and the atomizing chamber 39. As long as the droplets that enter the air intake channel 361 from the atomizing chamber 39 under the action of gravity can be gathered by the first channel wall 353, and the droplets can be directly dripped into the air intake channel 361.

[0037] In some embodiments, to avoid the first channel wall 353 being too large in the first direction and affecting the processing difficulty of the support frame 35, the opening 3621 of the sensing air channel 362 is provided at the end of the air intake channel 361 facing the atomizing chamber 39 in the first direction. For example, the opening 3621 of the sensing air channel 362 can be formed by the sealing member 36 and the bottom wall of the groove of the support frame 35. The length of the first channel wall 353 can also be shortened by reducing the size of the opening 3621 in the first direction, which facilitates the manufacturing of the support frame 35.

[0038] Of course, in other embodiments, the opening 3621 of the sensing airway 362 may be located on the seal 36 and spaced apart from the bottom wall of the mounting groove 351 on the support frame 35 in the first direction.

[0039] In some embodiments, please continue to refer to Figure 2The intake channel 361 is provided with an intake chamber 3612 and an intake duct 3611. The cross-sectional area of ​​the intake chamber 3612 perpendicular to the first direction is larger than the cross-sectional area of ​​the intake duct 3611 perpendicular to the first direction. In the first direction, the intake chamber 3612 is located between the intake duct 3611 and the connecting channel 352. The intake duct 3611 is connected to the connecting channel 352 through the intake chamber 3612. The opening 3621 of the sensing duct 362 is provided on the cavity wall of the intake chamber 3612. The intake chamber 3612 is directly opposite the connecting channel 352 in the first direction. The atomized liquid or condensate entering the intake chamber 3612 from the atomizing chamber 39 can adhere to the cavity wall of the intake chamber 3612, which can reduce the probability of the atomized liquid or condensate clogging the intake channel 361.

[0040] Of course, in other embodiments, if the cross-sectional area of ​​the air intake channel 361 is large enough to ensure that the atomizing liquid or condensate will not block the air intake channel 361, the air intake chamber 3612 can be omitted, and the air intake channel 361 as a whole can be a channel with equal cross-sectional dimensions everywhere.

[0041] In some embodiments, please refer to Figure 2 In a plane perpendicular to the first direction, the intake airway 3611 and the sensing airway 362 are arranged on both sides of the connecting channel 352. This increases the distance between the opening 3621 of the sensing airway 362 and the intake airway 3611, reducing the probability of liquid entering the sensing airway 362. Of course, in other embodiments, the intake airway 3611 and the sensing airway 362 can be arranged on the same side of the connecting channel 352, as long as the protruding first channel wall 353 can reduce the probability of liquid entering the sensing airway 362 from the opening 3621.

[0042] In some embodiments, the opening of the air intake chamber 3612 is arranged with the bottom wall of the chamber in a first direction. The opening of the air intake chamber 3612 faces the connecting channel 352. The opening 3621 of the sensing air passage 362 is located on the side wall of the air intake chamber 3612. The air intake channel 361 is located on the bottom wall of the air intake chamber 3612. The bottom wall of the air intake chamber 3612 has a guiding surface 3613. The guiding surface 3613 can be an inclined surface or a curved surface. The distance between the guiding surface 3613 and the atomizing chamber 39 in the first direction gradually decreases in the direction from the air intake channel 3611 to the sensing air passage 362. In this way, the guiding surface 3613 can guide the atomized liquid or condensate adhering to the bottom wall of the air intake chamber 3612 to flow to the air intake channel 3611, avoiding the accumulation of condensate or atomized liquid in the air intake chamber 3612, and further reducing the probability of liquid entering the sensing air passage 362.

[0043] Alternatively, the opening 3621 of the sensing airway 362 and the bottom wall of the air inlet chamber 3612 can be arranged at an interval. In this way, even if the bottom wall of the air inlet chamber 3612 is perpendicular to the first direction and there is residual atomized liquid or condensate in the air inlet chamber 3612, the probability of residual condensate or atomized liquid entering the sensing airway 362 through the opening 3621 can be reduced.

[0044] In some embodiments, please continue to refer to Figure 2 Alternatively, the sensing airway 362 can be configured as a bent airway to reduce the probability of liquid seeping into the pressure sensor 7 through contact with it from the opening 3621 along the sensing airway 362. For example, if the opening 3621 of the sensing airway 362 is oriented perpendicular to the first direction, and the sensing airway 362 extends entirely in the first direction, the liquid entering the sensing airway 362 from the opening 3621 needs to pass through a bent path. This bent path provides some degree of resistance to the liquid, thus reducing the probability of liquid seeping into the pressure sensor 7.

[0045] In other embodiments, the number of bends in the sensing airway 362 between the opening 3621 of the sensing airway 362 and the pressure sensor 7 can be increased to further reduce the probability of liquid seeping into the pressure sensor 7.

[0046] In some embodiments, please continue to refer to Figure 2 The connecting channel 352 is directly opposite the atomizing surface of the atomizing core 33 in the atomizing chamber 39 in the first direction. The atomizing core 33 includes a heating element disposed on the atomizing surface, that is, the connecting channel 352 is arranged directly opposite the heating element. The channel wall of the connecting channel 352 has a second channel wall 354 protruding into the atomizing chamber 39. The arrangement of the second channel wall 354 can reduce the distance between the air outlet of the connecting channel 352 and the atomizing surface, which can increase the rate at which the airflow blows toward the atomizing surface, which helps to fully mix the airflow with the aerosol at the atomizing surface. In addition, the higher airflow rate can also cool the heating element on the atomizing surface, avoid the heating element temperature from being too high, and help to extend the service life of the atomizing core 33 and the heating element.

[0047] In addition, the second channel wall 354 can form a recess in the atomizing chamber 39 to collect the atomized liquid or condensate in the atomizing chamber 39, reducing the probability that the atomized liquid or condensate will enter the air intake channel 361 from the atomizing chamber 39. On the other hand, since there is a liquid suction member 37 in the atomizing chamber 39, the position of the liquid suction member 37 can be restricted by the second channel wall 354 to prevent the liquid suction member 37 from blocking the connecting channel 352.

[0048] In some embodiments, please refer to Figure 2 and Figure 3The main body 100 of the atomizing device also includes a shell 1, a mouthpiece 2, a power supply shell 4, and a battery 5. The shell 1 is a cylindrical structure extending in the first direction. During the assembly of the atomizing device, the control module 6 and the battery 5 need to be electrically connected and then sequentially filled into the power supply shell 4. Then, the power supply shell 4 and the atomizing component 3 are sequentially assembled in the shell 1, so that the control module 6 and the atomizing core 33 are electrically connected through the connecting electrode 34, and the atomizing component 3 is sealed with the power supply shell 4 through the support frame 35. Finally, the mouthpiece 2 is assembled on the shell 1, thus realizing the assembly of the entire atomizing device.

[0049] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
