Description

Technical Field

[0001] This application relates to the field of atomization technology, specifically to an atomization device. Background Technology

[0002] The atomizing device has a liquid storage chamber, an atomizing chamber, an air inlet channel, and an atomizing channel. The liquid storage chamber is used to store atomizing liquid. The atomizing liquid in the liquid storage chamber can enter the atomizing chamber and be heated by the heating element to generate aerosol. External gas can enter the atomizing chamber through the air inlet channel, mix with the aerosol generated in the atomizing chamber, and then be discharged from the atomizing channel.

[0003] Atomizing devices typically include an airflow sensor, which connects to the air intake channel via a sensing air passage. The airflow sensor detects the air pressure within the air intake channel, and the atomizing device's control module uses this sensor's readings to control the heating element to heat up or stop heating. Normally, the air intake channel is located below the liquid storage chamber and the atomizing chamber. This means that leakage from the liquid storage chamber and condensation from aerosol backflow in the atomizing chamber can enter the air intake channel under gravity, coming into contact with the airflow sensor along the sensing air passage. This can cause a short circuit in the airflow sensor, preventing the atomizing device from functioning properly. Utility Model Content

The first airway is located on the side of the second airway facing the outlet of the atomizing channel in the first direction.

[0012] In one alternative embodiment, the storage cavity has a first cavity wall facing the outlet of the atomizing channel in the first direction; the device body includes a connecting tube that encloses at least a portion of the connecting airway, one end of the connecting tube extending into the storage cavity in the first direction, the connecting tube having an outer flange that abuts against the first cavity wall in the first direction.

[0013] In one optional embodiment, the main body of the device includes a power supply component, an atomizing component, and a storage component.

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 provides an atomizing device; please refer to [reference needed]. Figures 1 to 4 The atomizing device includes a device body 100 and an airflow sensor 200. The airflow sensor 200 is installed in the device body 100. The device body 100 has an atomizing channel 122, an atomizing chamber 121 and a sensing air passage 2. The atomizing channel 122 extends in a first direction, which can be understood as the up and down direction of the atomizing device in use. In the use state of the atomizing device, the outlet of the atomizing channel 122 faces upward.

[0027] The atomizing chamber 121 connects the sensing airway 2 and the atomizing channel 122. The sensing airway 2 is also fluidly connected to the airflow sensor 200. The air pressure in the sensing airway 2 can be detected by the airflow sensor 200. The control module 37 in the atomizing device can control the heating element 131 in the atomizing device to heat up according to the detection result of the airflow sensor 200. If the airflow sensor 200 detects that the sensing airway 2 is in a negative pressure state when the user inhales, the control module 37 controls the heating element 131 to heat up according to the detection result of the airflow sensor 200. When the airflow sensor 200 detects that the sensing airway 2 is in a normal pressure state, the control module 37 controls the heating element 131 to stop heating according to the detection result of the airflow sensor 200. In this way, the heating element 131 can be automatically controlled by the control module 37 and the airflow sensor 200 when the atomizing device is in use.

[0028] The improvement of the atomizing device in this application lies in the structure of the sensing airway 2. Please refer to [reference needed]. Figure 2 and Figure 3The sensing airway 2 includes a first airway 143 and a second airway 391 arranged in a first direction. Both the first airway 143 and the second airway 391 have two openings. The two openings of the first airway 143 are located at both ends of the first airway 143 in the first direction, and the two openings of the second airway 391 are located at both ends of the second airway 391 in the first direction. The first airway 143 communicates with the second airway 391. The first airway 143 is located between the second airway 391 and the outlet of the atomizing channel 122 in the first direction. That is, when the atomizing device is in use, the second airway 391 is located within the first airway. The lower end of 143; the side wall of the second air passage 391 extends into the first air passage 143 in the first direction. The side wall of the second air passage 391 is arranged at intervals with the side wall of the first air passage 143. In this way, the leaked and returned condensate in the atomizing device can flow along the side wall of the first air passage 143 to the outside of the side wall of the second air passage 391 under the action of gravity. This can reduce the probability of the leaked and returned condensate entering the second air passage 391 from the first air passage 143, thereby reducing the probability of the leaked and returned condensate contacting the airflow sensor 200. This helps to improve the working stability of the atomizing device and ensure the normal operation of the atomizing device.

[0029] In some embodiments, please refer to Figure 2 In the first air passage 143, the opening away from the second air passage 391 in the two openings at both ends in the first direction is the first opening 1431. In the second air passage 391, the opening facing the outlet of the atomizing channel 122 in the two openings at both ends in the first direction is the second opening 3911. The second opening 3911 of the second air passage 391 is located inside the first air passage 143 and is connected to the first air passage 143. The first opening 1431 and the second opening 3911 are staggered in a plane perpendicular to the first direction, which can further reduce the probability of leakage and backflow condensate entering the second air passage 391 from the first air passage 143.

[0030] In some embodiments, the first air passage 143 extends entirely in a first direction, and airflow can flow within the first air passage 143 in the first direction. The first air passage 143 has two openings at both ends in the first direction, and the size of the first opening 1431 is smaller than the size of the end opening near the second air passage 391 in the first direction. The size of the second opening 3911 of the second air passage 391 is much smaller than the size of the end opening of the second air passage 391. The second opening 3911 is located inside the end opening of the first air passage 143 and faces the sidewall of the first air passage 143 whose extension direction is perpendicular to the first direction in the first direction.

[0031] In some embodiments, the first airway 143 can also be a bent airway, with the openings at both ends of the first airway 143 facing the first direction, and the second opening 3911 of the second airway 391 facing the first direction. Alternatively, the second opening 3911 can be positioned directly opposite the first opening 1431 in the first direction, as long as the leakage and return condensate in the first airway 143 flow along the through sidewall of the first airway 143 to the outside of the sidewall of the second airway 391 under the action of gravity.

[0032] In some embodiments, please continue to refer to Figure 2 The sensing airway 2 also includes a first cavity 141, which is located at the end of the first airway 143 facing the outlet of the atomizing channel 122 in a first direction. The first cavity 141 is connected to the atomizing cavity 121, and the arrangement direction of the first cavity 141 and the atomizing cavity 121 is perpendicular to the first direction. The sidewall of the first airway 143 extends into the first cavity 141 in the first direction and surrounds the cavity wall of the first cavity 141 to form a first receiving groove 1411. The opening of the first receiving groove 1411 faces the outlet of the atomizing channel 122 in the first direction. The cavity wall of the first cavity 141 includes a cavity sidewall extending in a first direction. The sidewall of the first air passage 143 can be arranged at intervals with the sidewall of the first cavity 141, so that the first receiving groove 1411 can form an annular groove surrounding the first air passage 143. The sidewall of the first air passage 143 can also be connected to the sidewall of the first cavity 141, so that part of the cavity wall of the first cavity 141 forms the sidewall of the first air passage 143. The arrangement direction of the first receiving groove 1411 and the first air passage 143 is perpendicular to the first direction. In this way, the first receiving groove 1411 can collect part of the leakage and backflow condensate that enters the first cavity 141 from the atomizing cavity 121, thereby reducing the probability of leakage and backflow condensate entering the first air passage 143 from the atomizing cavity 121 through the first cavity 141. It also helps to reduce the probability of leakage and backflow condensate contacting the airflow sensor 200, thereby improving the working stability of the atomizing device and ensuring the normal operation of the atomizing device.

[0033] In some embodiments, please continue to refer to Figure 2 The first cavity 141 has a third opening 1412 on its cavity wall that communicates with the atomizing cavity 121. The orientation of the third opening 1412 can be perpendicular to the first direction. In the plane perpendicular to the first direction, the third opening 1412 is located on the side of the first cavity 141 facing the atomizing cavity 121. The first air passage 143 is located at the end of the first cavity 141 away from the atomizing cavity 121 in the plane perpendicular to the first direction. In this way, the first air passage 143 and the third opening 1412 are arranged at both ends of the first cavity 141 in the vertical first direction, which can increase the distance between the third opening 1412 and the first air passage 143, thereby reducing the probability of leakage and backflow condensate entering the first air passage 143 from the third opening 1412.

[0034] In some embodiments, please refer to Figure 3 The sidewall of the first air passage 143 has a first end face 1432 located in the first cavity 141 in the first direction. The first end face 1432 faces the first direction and is located on the side of the third opening 1412 facing the outlet of the atomizing channel 122 in the first direction. By setting the first end face 1432 higher than the third opening 1412 and by increasing the distance between the first end face 1432 and the third opening 1412, the probability of droplets entering the first air passage 143 from the third opening 1412 against gravity can be reduced, thereby further reducing the probability of leakage and backflow condensate entering the first air passage 143.

[0035] Of course, in other embodiments, the first cavity 141 is located between the atomizing cavity 121 and the first air passage 143 in the first direction, and the third opening 1412 faces the first direction. The third opening 1412 and the first opening 1431 of the first air passage 143 are staggered in a plane perpendicular to the first direction. In this way, some of the leaked liquid and reflux condensate can be collected and stored through the first receiving tank 1411, reducing the probability of leaked liquid and reflux condensate entering the first air passage 143.

[0036] In some embodiments, please refer to Figures 2 to 4 The sensing airway 2 also includes a storage cavity 394 and a connecting airway 52. ​​The storage cavity 394 is located between the second airway 391 and the connecting airway 52 in a first direction. The storage cavity 394 is located on the side of the second airway 391 away from the outlet of the atomizing channel 122 in the first direction. The connecting airway 52 is located on the side of the storage cavity 394 away from the second airway 391 in the first direction. The storage cavity 394 connects the second airway 391 and the connecting airway 52. ​​The atomizing device has a mounting cavity. The airflow sensor 200 is located in the mounting cavity. The connecting airway 52 extends in a first direction. One end of the connecting airway 52 is open and connected to the storage cavity 394 in the first direction, and the other end is open and connected to the mounting cavity. In this way, fluid communication between the storage cavity 394 and the airflow sensor 200 in the mounting cavity can be achieved through the connecting airway 52, which can meet the requirement that the airflow sensor 200 can detect the air pressure in the sensing airway 2 when the atomizing device is working.

[0037] Furthermore, the second air passage 391 also extends in the first direction, and the connecting air passage 52 and the second air passage 391 are staggered in a plane perpendicular to the first direction. In this way, the liquid droplets flowing from the side wall of the second air passage 391 to the storage cavity 394 under the action of gravity can be collected and stored through the storage cavity 394. This can reduce the probability of leakage and backflow condensate entering the connecting air passage 52 from the second air passage 391 through the storage cavity 394, thereby reducing the probability of liquid contacting the airflow sensor 200 and helping to ensure the normal operation of the atomizing device.

[0038] In some embodiments, please refer to Figure 4The sidewall of the connecting airway 52 extends into the storage cavity 394 in the first direction. The storage cavity 394 has a side wall extending in the first direction. The sidewall of the connecting airway 52 and the side wall of the storage cavity 394 can be staggered in a plane perpendicular to the first direction, or the sidewall of the connecting airway 52 can also contact or connect with the side wall of the storage cavity 394. The sidewall of the connecting airway 52 and the wall of the storage cavity 394 enclose each other in the storage cavity 394 to form a second receiving groove 331. The opening of the second receiving groove 331 faces the outlet of the atomizing channel 122 in the first direction. In this way, the amount of liquid stored in the storage cavity 394 can be increased by the second receiving groove 331, further reducing the probability of leakage and backflow condensate entering the connecting airway 52 from the storage cavity 394, further reducing the probability of liquid contacting the airflow sensor 200, and ensuring the normal operation of the atomizing device.

[0039] In some embodiments, the connecting airway 52 may not extend into the storage cavity 394. Alternatively, the volume of the storage cavity 394 may be increased to increase the wall area of ​​the storage cavity 394 to which liquid can adhere, thereby reducing the probability of liquid entering the connecting airway 52.

[0040] In some embodiments, please continue to refer to Figure 4 The storage cavity 394 has a first cavity wall 332, which is connected to the side cavity wall of the storage cavity 394. The first cavity wall 332 faces the outlet of the atomizing channel 122 in a first direction. The first cavity wall 332 forms the bottom side wall of the storage cavity 394. The side wall of the air passage 52 protrudes from the first cavity wall 332 of the storage cavity 394 in a first direction. The device body 100 includes a connecting tube 5 extending in a first direction. The connecting tube 5 can be embedded in other components in the device body 100. The connecting tube 5 has a central channel that forms at least part of the connecting air passage 52. One end of the connecting tube 5 in the first direction extends into the storage cavity 394. The connecting tube 5 has an outer flange 51 extending perpendicularly to the first direction. The outer flange 51 is located in the storage cavity 394 and can abut against the first cavity wall 332 of the storage cavity 394 in the first direction to determine the position of the connecting tube 5 in the device body 100 and ensure that the side wall of the connecting air passage 52 extends into the storage cavity 394.

[0041] In some embodiments, the device body 100 does not have a connecting pipe 5, and the component forming the connecting air passage 52 in the device body 100 has a protrusion extending into the storage cavity 394, with the end opening of the connecting air passage 52 located on the protrusion.

[0042] In some embodiments, please continue to refer to Figures 2 to 4The main body 100 of the device includes a power supply component 3 and an atomizing component 1. The atomizing component 1 has a liquid storage chamber 111 arranged around the atomizing channel 122 and the atomizing chamber 121. The liquid storage chamber 111 is used to store atomizing liquid. The liquid in the liquid storage chamber 111 can enter the atomizing chamber 121 to heat the atomizing liquid through the heating element 131 in the atomizing chamber 121 to generate aerosol. The aerosol generated in the atomizing chamber 121 can be discharged from the atomizing channel 122. The atomizing assembly 1 includes an atomizing shell 11, an atomizing base 14, and an atomizing bracket 12. The atomizing shell 11 has openings at both ends in a first direction, with one end forming the outlet of the atomizing channel 122. The atomizing base 14 is sealed and installed at the other end opening of the atomizing shell 11. The atomizing bracket 12 is located inside the atomizing shell 11 and extends in the first direction. One end of the atomizing bracket 12 is sealed to the atomizing shell 11, and the other end is sealed to the atomizing base 14. The atomizing chamber 121 is located inside the atomizing bracket 12. The atomizing core 13 in the atomizing assembly 1 is installed in the atomizing chamber 121 and is fixed relative to the atomizing bracket 12. The atomizing channel 122 is formed by the atomizing bracket 12 and the atomizing shell 11. The first cavity 141 and the first air passage 143 in the device body 100 are both located in the atomizing assembly 1 and are disposed on the atomizing base 14.

[0043] The power supply assembly 3 includes a power supply housing 32, a power supply bracket 33, a battery cell 36, and a control module 37. The control module 37 includes a circuit board 371 and electronic components mounted on the circuit board 371. The power supply bracket 33 is installed inside the power supply housing 32. The control module 37 and the battery cell 36 are both located inside the power supply housing 32 and are mounted on the power supply bracket 33, or fixed relative to the power supply bracket 33. The power supply assembly 3 also includes a rubber component 38, which is fixed relative to the power supply bracket 33. The rubber component 38 has a mounting groove, and the rubber component 38 and the circuit board 371 enclose each other at the mounting groove to form a mounting cavity. The airflow sensor 200 is electrically connected to the circuit board 371 and is installed in the mounting cavity.

[0044] The power supply component 3 has a slot 31, the opening of which faces the atomizing component 1 in a first direction. The atomizing component 1 is located inside the slot 31 and is electrically connected to the power supply component 3. The rubber part 38 has an installation channel communicating with the mounting slot. A portion of the connecting tube 5 is located within the installation channel. The connecting tube 5 is embedded in the rubber part 38. The central channel of the connecting tube 5 and the installation channel enclose a connecting air passage 52 communicating with the mounting cavity. The connecting tube 5 passes through the power supply bracket 33 in a first direction. The outer flange 51 abuts against the first cavity wall 332 of the power supply bracket 33 in a first direction. Thus, the rubber part 38 and the power supply bracket 33 are relatively fixed through the connecting tube 5.

[0045] In some embodiments, after the atomizing component 1 and the power supply component 3 are inserted into place, the atomizing component 1 and the power supply component 3 form a storage cavity within the slot 31, and the second air passage in the sensing air passage 2 can be located on the atomizing base 14 of the atomizing component 1.

[0046] In some embodiments, please continue to refer to Figure 2 and Figure 3 The main body 100 of the device also includes a storage component 39, which is located in the slot 31 of the power supply component 3. The storage component 39 and the slot wall of the slot 31 form a storage cavity 394. The second air channel 391 can be located on the storage component 39. There is no connection between the side wall of the second air channel 391 and the side wall of the first air channel 143. During the assembly of the atomizing component 1 and the power supply component 3, it is sufficient to ensure that the side wall of the second air channel 391 on the storage component 39 is inserted into the first air channel 143 of the atomizing base 14.

[0047] In some embodiments, the storage component 39 may be enclosed with the power supply housing 32 and the power supply bracket 33 to form a storage cavity 394; or the storage component 39 may be enclosed only with the power supply bracket 33 to form a storage cavity 394. The power supply bracket 33 is equipped with a power supply electrode 35 that is electrically connected to the atomizing component 1. The storage cavity 394 is arranged around the power supply electrode 35. The power supply bracket 33 forms the bottom wall of the storage cavity 394 on the side facing the atomizing component 1 in the first direction. The outer flange 51 of the connecting tube 5 abuts against the side of the bottom wall formed on the power supply bracket 33, that is, the side of the first cavity wall 332 facing the outlet of the atomizing channel 122 in the first direction.

[0048] In some embodiments, please continue to refer to Figure 2 and Figure 3 In the power supply assembly 3, a recessed groove 34 is provided on the bottom wall of the slot 31. This recessed groove 34 can be formed by the power supply housing 32 and the power supply bracket 33. The recessed groove 34 surrounds the power supply electrode 35. The storage component 39 is located inside the recessed groove 34. The storage component 39 has a groove 392. The opening of the groove 392 faces the bottom wall of the recessed groove 34 in a first direction. A second air passage 391 is provided on the bottom wall of the groove 392. The side wall of the groove 392 and the side wall of the recessed groove 34 are sealed together to form a storage cavity 394, which helps to improve the sealing performance of the storage cavity 394 and reduce the probability of liquid leakage from the storage cavity 394. To facilitate the installation of the storage component 39, the storage component 39 can be made of rubber material or deformable plastic material.

[0049] In some embodiments, the groove 392 is omitted from the storage component 39, and the storage component 39 is a sheet structure. After the atomizing component 1 and the power supply component 3 are inserted into place, the storage component 39 is sealed and pressed between the atomizing component 1 and the power supply bracket 33. The storage component 39 and the recess 34 in the power supply component 3 enclose the storage cavity 394.

[0050] In some embodiments, please continue to refer to Figure 2 and Figure 3 The atomizing device has an air inlet 321, which is located on the power supply component 3. For example, the air inlet 321 can be located on the power supply housing 32. The power supply bracket 33 has a cavity that communicates with the air inlet 321. The storage component 39 is provided with a clearance channel 393, or the storage component 39 and the power supply bracket 33 enclose each other to form a clearance channel 393. The atomizing component 1 has an air inlet chamber 142 that communicates with the atomizing chamber 121. The air inlet chamber 142 is located on the atomizing base 14. The air inlet chamber 142 and the first chamber 141 are arranged on both sides of the atomizing chamber 121, and the air inlet chamber 142 and the first chamber 141 are symmetrically arranged about the atomizing chamber 121 to facilitate the processing of the atomizing bracket 12.

[0051] After the atomizing component 1 and the power supply component 3 are inserted into place, the air inlet 321 can be connected to the air inlet chamber 142 through the cavity and the clearance channel 393 in sequence. External gas can enter the atomizing chamber 121 from the air inlet 321 along the clearance channel 393 and the air inlet chamber 142 to supply gas to the atomizing chamber 121.

[0052] The clearance channel 393 on the storage component 39 is not connected to the storage cavity 394. The storage component 39 is provided with a groove 392. The groove sidewall of the groove 392 and the groove sidewall of the sink 34 are sealed together to effectively prevent the clearance channel 393 from being connected to the storage cavity 394. This avoids the need to provide a separate structure on the storage component 39 to separate the storage cavity 394 from the clearance channel 393.

[0053] In other embodiments, the air inlet 321 is located on the side wall of the slot 31. After the atomizing component 1 and the power supply component 3 are inserted into place, the air inlet 321 can be directly connected to the atomizing chamber 121 through the air inlet chamber 142 on the atomizing component 1. This avoids the need to set an additional clearance channel 393 on the storage component 39.

[0054] 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.
