Description

Technical Field

[0001] This invention relates to the field of electronic atomization device technology, specifically to an electronic atomization device and its control method. Background Technology

[0002] Electronic atomizing devices are electronic products that atomize an aerosol-generating liquid to produce an aerosol for users to inhale. The aerosol-generating liquid can be water, flavorings, or medicinal liquids, among other things. They have a wide range of applications, including air conditioning and disease treatment. Existing electronic atomizing devices include a housing containing an atomizing component, a battery, and an airflow sensor. The device uses the airflow sensor to detect the user's inhalation action, controlling the battery power to heat the heating element within the atomizing component, thus atomizing the aerosol-generating liquid to form an aerosol.

[0003] In existing e-cigarette devices, the airflow sensor and battery are typically installed at the end of the atomizing assembly furthest from the user, with the atomizing assembly positioned between the user and the airflow sensor, and the battery and atomizing assembly coaxially arranged. However, when the e-cigarette device is placed vertically or when the user inhales from it, condensate formed by aerosol condensation and leaked aerosol generator liquid can easily flow into the airflow sensor. This condensate and leaked aerosol generator liquid can clog the airflow sensor, causing it to malfunction and preventing the e-cigarette device from starting, resulting in a short lifespan for the device. Summary of the Invention

[0012] Preferably, the cross-sectional area of ​​the thrust plug is equal to the cross-sectional area of ​​the air inlet groove, and the distance between the thrust plug and the top wall of the air inlet groove is greater than the distance between the baffle arm and the opening of the air outlet groove facing away from the first cavity.

[0013] Preferably, the electronic atomizing device further includes a fan located in the first cavity, the fan being electrically connected to the controller and used to drive airflow toward the air inlet when the user's mouth leaves the mouthpiece.

[0014] Preferably, the surface of the elastic top cover facing away from the second cavity is provided with a liquid storage tank, and the liquid storage tank is connected to the mist outlet, the air outlet and the atomizing component.

[0015] Preferably, the air outlet includes a first ventilation section, a second ventilation section, and a ventilation connection section. The first ventilation section is connected to the airflow sensor. The second ventilation section is located at the bottom wall of the liquid storage tank and is connected to the liquid storage tank. The first end of the ventilation connection section is connected to the first ventilation section, and the second end of the ventilation connection section is connected to the second ventilation section. The extension direction of the ventilation connection section is different from the extension directions of the first ventilation section and the second ventilation section.

[0016] Preferably, the air outlet groove is provided with a plurality of spaced liquid-blocking grooves.

[0017] In a second aspect, the present invention provides a control method for an electronic atomizing device as described in any of the first aspects above, comprising the following steps:

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] By arranging a first chamber and a second chamber side-by-side, the first chamber houses the battery, while the second chamber houses the porous liquid intake and atomizing components. An airflow sensor is installed at the position corresponding to the first chamber on the flexible top cover, preventing the aerosol generated in the porous liquid intake from flowing into the airflow sensor. When not in use, i.e., in the first state, the air baffle extends into the air outlet slot to prevent communication between the airflow sensor and the mist outlet, thus preventing condensate and leaking aerosol from flowing into the airflow sensor. The air outlet slot is opened automatically when the user inhales, based on the temperature sensor's automatic detection of the user's usage status. Therefore, it effectively prevents aerosol, condensate, and leaked aerosol generated liquid from flowing into the airflow sensor, thereby improving the lifespan of the electronic atomizing device. Furthermore, its structure is compact and cost-effective. Attached Figure Description

[0036] To address the shortcomings of existing electronic atomizing devices where condensate and leaked aerosol generator liquid easily flow into the airflow sensor 93, leading to a short service life, this invention provides... Figures 1 to 5 The electronic cigarette atomizing device shown is a housing 1, a mouthpiece 2, a flexible top cover 3, an air baffle 4, a temperature sensor 5, and a motor 6. The housing 1 has a first chamber 101 and a second chamber 102 arranged in parallel. The first chamber 101 houses a battery 7 and a controller 8 electrically connected to the battery 7. The second chamber 102 houses a porous liquid suction 91 and an atomizing component 92 electrically connected to the battery 7.

[0037] The porous liquid absorber 91 can be made of materials such as natural fibers, synthetic fibers, or ceramics. In this embodiment, the atomizing component 92 includes a liquid-guiding cotton 921 and a heating wire 922 in contact with the liquid-guiding cotton 921. The liquid-guiding cotton 921 contacts the porous liquid absorber 91 to absorb the aerosol-generating liquid at the porous liquid absorber 91 and conducts the aerosol-generating liquid to the heating wire 922 for atomization. The controller 8 is electrically connected to the heating wire 922 to control the battery 7 to supply power to the heating wire 922. It is understood that as long as the aerosol-generating liquid can be atomized, the structure of the atomizing component 92 is not specifically limited here.

[0038] In this embodiment, the housing 1 includes a first sleeve 11, a second sleeve 12, and a third sleeve 13. The second sleeve 12 is detachably disposed within the first sleeve 11. A first cavity 101 is formed between the first sleeve 11 and the second sleeve 12, and a second cavity 102 is formed within the second sleeve 12. The first sleeve 11 is located within the third sleeve 13, and a tubular heat-insulating gap 14 is formed between the third sleeve 13 and the first sleeve 11, thus preventing overheating of the outside of the third sleeve 13 during use. One end of the third sleeve 13 is connected to a bottom cover 15.

[0039] The nozzle 2 is connected to the first sleeve 11, the second sleeve 12, and the third sleeve 13. The bottom cover 15 and the nozzle 2 are located at opposite ends of the third sleeve 13. The nozzle 2 is provided with a mist outlet 21 that communicates with the atomizing component 92. The elastic top cover 3 is located inside the nozzle 2 and is sealed to the openings of the first cavity 101 and the second cavity 102. Therefore, the aerosol generating liquid in the second cavity 102 is not easily leaked out and flows into the first cavity 101.

[0040] The elastic top cover 3 has a mounting groove 31 and an air inlet groove 32 at one end corresponding to the position of the first cavity 101, with the mounting groove 31 located above the air inlet groove 32. An airflow sensor 93 is installed at the position corresponding to the first cavity 101 on the elastic top cover 3. Specifically, the airflow sensor 93 is located within the mounting groove 31. The air inlet groove 32 is located on the lower surface of the elastic top cover 3 and communicates with the first cavity 101 and the airflow sensor 93. Figure 2 As shown, the airflow sensor 93 is located to the upper left of the porous liquid absorber 91. Even if the aerosol-generating liquid of the porous liquid absorber 91 leaks in the second chamber 102, it is not easy to flow into the airflow sensor 93, thereby better protecting the airflow sensor 93.

[0041] The elastic top cover 3 has an air outlet groove 33 on its surface facing away from the first cavity 101. Preferably, the air outlet groove 33 extends along the lateral direction of the electronic atomizing device and communicates with the airflow sensor 93 and the mist outlet 21. That is, the extension direction of the air outlet groove 33 is perpendicular to the extension direction of the first cavity 101 and the extension direction of the second cavity 102. Therefore, condensate and leaked aerosol generating liquid are less likely to flow into the airflow sensor 93.

[0042] The bottom wall of the air outlet 33 is provided with an insertion hole 34 that communicates with the first cavity 101. The insertion hole 34 extends along the longitudinal direction of the electronic atomizing device. A liquid storage tank 35 is provided on the surface of the elastic top cover 3 facing away from the second cavity 102. The liquid storage tank 35 is located between the mist outlet 21 and the porous liquid absorbent 91, and is connected to the mist outlet 21, the air outlet 33, and the atomizing component 92. Therefore, the condensate formed by aerosol condensation at the mist outlet 21 can be collected in the liquid storage tank 35, reducing the probability of the user inhaling the condensate. In this embodiment, the bottom wall of the liquid storage tank 35 is provided with a vent hole 351, which communicates with the mist outlet 21 and the atomizing component 92. The liquid storage tank 35 contains absorbent cotton 90, which absorbs the condensate, thus preventing the condensate from spreading.

[0043] Preferably, the venting channel 33 includes a first venting section 331, a second venting section 332, and a venting connection section 333. The first venting section 331 is connected to the airflow sensor 93. The second venting section 332 is located at the bottom wall of the liquid storage tank 35 and is connected to the liquid storage tank 35. The first end of the venting connection section 333 is connected to the first venting section 331, and the second end of the venting connection section 333 is connected to the second venting section 332. The extending direction of the venting connection section 333 is different from the extending directions of the first venting section 331 and the second venting section 332. Therefore, the condensate in the liquid storage tank 35 does not easily flow towards the airflow sensor 93.

[0044] More preferably, when placed vertically, the height of the bottom wall of the first ventilation section 331 is higher than the height of the bottom wall of the second ventilation section 332, so even when the electronic atomizing device is shaken horizontally, the condensate is less likely to flow into the airflow sensor 93. To better prevent the condensate from flowing towards the airflow sensor 93, a plurality of spaced-apart liquid-blocking grooves 334 are provided in the air outlet groove 33. In one embodiment, the liquid-blocking grooves 334 are capillary grooves, thus enabling good adsorption of the condensate. It is understood that the elastic top cover 3 can be a silicone cover or a polyurethane cover, etc., as long as it is elastic, and its material is not specifically limited here.

[0045] The air-blocking block 4 is movably inserted into the insertion hole 34 and connected to the motor 6. In the first state, the air-blocking block 4 extends into the air outlet groove 33 to prevent the airflow sensor 93 from communicating with the mist outlet 21. In the second state, the air-blocking block 4 is spaced at a preset distance from the air outlet groove 33. The preset distance can be set as needed and is not specifically limited here. The temperature sensor 5 is located on the outer surface of the mouthpiece 2 and is electrically connected to the controller 8. The temperature sensor 5 may include a resistance temperature detector (RTD) or a thermocouple. In this embodiment, the temperature sensor 5 is arranged around the mouthpiece 2, so it is in contact with the user's mouth whenever the user inhales.

[0046] The controller 8 is electrically connected to the battery 7 and the atomizing assembly 92, and is used to control the motor 6 to turn on or off according to the temperature signal sent by the temperature sensor 5. The motor 6 is electrically connected to the controller 8, and is used to drive the air baffle 4 to move along the guide direction of the socket 34 according to the control signal of the controller 8.

[0047] The electronic atomizing device also includes a sealing sheet 94, which is located on the side of the elastic top cover 3 facing away from the first cavity 101 and covers the opening of the air outlet groove 33 to seal the opening on the side facing away from the first cavity 101. Therefore, when the user inhales at the mouthpiece 2, the airflow in the mounting groove 31 area can quickly flow towards the mist outlet 21, thereby quickly triggering the airflow sensor 93, thus improving the sensitivity of the airflow sensor 93 and enhancing the user experience. Furthermore, this structure is easy to manufacture, reduces manufacturing processes, and improves production efficiency. It is understood that in the first state, the air-blocking block 4 abuts against the sealing sheet 94.

[0048] To ensure a more reliable fixation of the sealing sheet 94 and reduce its susceptibility to airflow, the sealing sheet 94 abuts against the suction nozzle 2, and the suction nozzle 2 and the elastic top cover 3 together clamp the sealing sheet 94. Preferably, the elastic top cover 3 is also provided with a receiving groove 36, in which the sealing sheet 94 is located. Therefore, it is easier to assemble during production, resulting in higher production efficiency, better positioning of the sealing sheet 94, and better reliability during use.

[0049] More preferably, the surface of the sealing sheet 94 facing away from the first cavity 101 and the surface of the elastic top cover 3 facing away from the first cavity 101 are located in the same plane. Therefore, the sealing sheet 94 can better seal the vent groove 33, preventing air leakage. In one embodiment, an adhesive layer is provided between the sealing sheet 94 and the elastic top cover 3, and the sealing sheet 94 is tightly connected to the elastic top cover 3 through the adhesive layer, thereby improving sealing performance and reliability. It is understood that the adhesive layer can be formed by curing adhesive glue. It is understood that in one embodiment, the sealing sheet 94 may not be necessary, and the opening of the vent groove 33 facing away from the first cavity 101 elastically abuts against the suction nozzle 2. In the first state, the air-blocking block 4 abuts against the suction nozzle.

[0050] The electronic atomizing device also includes an air-pushing plug 95 located in the first chamber 101, which is connected to the air-blocking block 4. In the first state, the air-pushing plug 95 is at least partially inserted into the air inlet groove 32. In the second state, the air-pushing plug 95 is spaced apart from the opening of the air inlet groove 32. That is, after the user finishes each puff, the motor 6 drives the air-blocking block 4 to move along the guide direction of the insertion hole 34, while the air-blocking block 4 drives the air-pushing plug 95 towards the air inlet groove 32. Therefore, after the user finishes each puff, the airflow in the air outlet groove 33 continues to move towards the smoke outlet through the drive of the air-pushing plug 95, preventing the aerosol remaining in the mouthpiece 2 from flowing into the airflow sensor 93. In addition, when the air-blocking block 4 moves to a preset position, it can isolate the airflow sensor 93 from the smoke outlet. This structure is ingenious, low in cost, easy to use, easy to implement, and effective.

[0051] Specifically, the air baffle 4 includes a connecting arm 41 extending horizontally and an air baffle arm 42 extending vertically. The connecting arm 41 is connected to the air baffle arm 42 and the motor 6, and the air pusher 95 is fixed at the connecting arm 41. The air baffle arm 42 extends into the insertion hole 34. In the first state, the air baffle arm 42 extends into the air outlet groove 33 and abuts against the sealing sheet 94. In the second state, the air baffle arm 42 and the air outlet groove 33 are spaced apart by a preset distance. This structure has the advantages of simple structure and high reliability.

[0052] Preferably, the cross-sectional area of ​​the push plug 95 is equal to the cross-sectional area of ​​the air inlet groove 32, and the distance between the push plug 95 and the top wall of the air inlet groove 32 is greater than the distance between the baffle arm 42 and the opening of the air outlet groove 33 facing away from the first cavity 101. In this embodiment, the distance between the push plug 95 and the top wall of the air inlet groove 32 is L1, and the distance between the baffle arm 42 and the opening of the air outlet groove 33 facing away from the first cavity 101 is L2, where L1 > L2. That is, during use, after the baffle arm 42 completely blocks the air outlet groove 33, the motor 6 continues to push the connecting arm 41 to move for a preset time, thereby making the air pressure at the airflow sensor 93 greater than the air pressure at the mist outlet 21. Therefore, even if too much condensate leaks from the air outlet groove 33 into the airflow sensor 93, it is not easy for it to leak into the airflow sensor 93. This structure effectively avoids the problem that if the air pressure at the airflow sensor 93 is lower than the air pressure at the mist outlet 21 during use, condensate can easily leak from the air outlet groove 33 into the airflow sensor 93.

[0053] It is understood that, in one embodiment, the cross-sectional area of ​​the upper opening of the insertion hole 34 is smaller than the cross-sectional area of ​​the baffle arm 42. Therefore, when the baffle arm 42 moves upward, the upper end of the wall of the insertion hole 34 bulges upward under the action of the baffle arm 42, thus pushing the condensate at the bottom wall of the air outlet groove 33 towards the liquid storage tank 35, thereby better protecting the airflow sensor 93. It is understood that the area of ​​the air outlet groove 33 located between the insertion hole 34 and the airflow sensor 93 is far from the mist outlet 21, thus making it less likely for a large amount of condensate to accumulate.

[0054] The electronic atomizing device also includes a fan 96 located in the first cavity 101 and a support plate 97 for fixing the fan 96 and the motor 6. The fan 96 is electrically connected to the controller 8 and is used to drive the airflow towards the air inlet 32 ​​when the user's mouth leaves the mouthpiece 2. By fanning the air inlet 32 ​​with the fan 96, not only can the aerosol remaining in the mouthpiece 2 area be blown out, making it less likely to produce a lot of condensate, but the condensate in the air outlet 33 can also be easily blown into the liquid storage tank 35.

[0055] Please see Figure 6 The present invention also discloses a control method for the electronic atomizing device as described above, comprising the following steps:

[0056] S1. Obtain the temperature signal transmitted by the temperature sensor 5;

[0057] The temperature sensor 5 collects the temperature at the nozzle 2 in real time, and the controller 8 acquires the temperature signal transmitted by the temperature sensor 5 and analyzes the signal. It is understood that the temperature signal can be an analog signal or a digital signal, and the choice can be made as needed; no specific limitation is made here.

[0058] S2. Based on the temperature signal, determine whether the user is about to inhale;

[0059] Since the temperature of the human oral cavity is between 36.3 and 37.2°C, when the temperature signal received by the controller 8 falls within this range, it indicates that the user is about to inhale. Of course, to accommodate people with various health conditions, the temperature range can be expanded, for example, to between 35 and 43°C.

[0060] S3. When it is determined that the user is about to inhale, control the motor 6 to drive the air baffle 4 to move so that the airflow sensor 93 is connected to the mist outlet 21.

[0061] When the electronic atomizing device is not in use, the air-blocking block 4 extends into the air outlet groove 33 to obstruct the airflow sensor 93 from communicating with the mist outlet 21. When the controller 8 determines that the user is about to inhale based on the temperature signal, the controller 8 controls the motor 6 to drive the air-blocking block 4 downwards so that the air outlet groove 33 communicates with the mist outlet 21.

[0062] S4. Obtain the inhalation start signal transmitted by the airflow sensor 93;

[0063] When the user inhales, the airflow sensor 93 is triggered, thereby sending an inhalation start signal to the controller 8.

[0064] S5. Based on the inhalation start signal, control the battery 7 to supply power to the atomizing component 92;

[0065] When the controller 8 receives the inhalation start signal, it controls the battery 7 to supply power to the atomizing component 92, which then atomizes the aerosol generating liquid to form an aerosol. The aerosol generating liquid can be water, fragrance, or medicinal liquid, as long as it can be atomized to form an aerosol; its material is not specifically limited here.

[0066] S6. Based on the temperature signal, determine whether the user has finished inhaling;

[0067] The controller 8 collects the temperature signal transmitted by the temperature sensor 5 in real time. When the user's mouth leaves the mouthpiece 2, the collected temperature is no longer between 36.3-37.2℃, indicating that the user has finished inhaling.

[0068] S7. When it is determined that the user has finished inhaling, the motor 6 is controlled to drive the air blocking block 4 to move toward the air outlet groove 33 to prevent the airflow sensor 93 from communicating with the mist outlet 21.

[0069] After inhalation, because the airflow sensor 93 is blocked from communicating with the mist outlet 21 by the air baffle 4, the airflow sensor 93 can be located in a relatively sealed space, and the aerosol and condensate remaining in the mouthpiece 2 are not easy to flow into the airflow sensor 93.

[0070] Preferably, the following steps are included before step S7:

[0071] When it is determined that the user has finished inhaling, the fan 96 is controlled to drive the airflow toward the air intake slot 32.

[0072] By fanning the air inlet 32 ​​with the fan 96, not only can the aerosol remaining in the area of ​​the suction nozzle 2 be blown out, making it less likely to produce a lot of condensate, but the condensate in the outlet 33 can also be easily blown into the storage tank 35.

[0073] Preferably, step S7 specifically includes:

[0074] When it is determined that the user has finished inhaling, the motor 6 is controlled to drive the air baffle 4 to move toward the air outlet 33. When the air baffle 4 comes into contact with the sealing sheet 94, the motor 6 continues to drive the air baffle 4 to move upward a preset distance to prevent the airflow sensor 93 from communicating with the mist outlet 21.

[0075] This method ensures that the air pressure at the airflow sensor 93 is greater than the air pressure at the smoke outlet, thus preventing excessive condensate from leaking into the airflow sensor 93 from the exhaust channel 33. Furthermore, the airflow sensor 93 is less likely to be falsely triggered.

[0076] In summary, firstly, since the first chamber 101 and the second chamber 102 are arranged side by side, with the battery 7 housed in the first chamber 101 and the porous liquid-absorbing 91 and atomizing component 92 housed in the second chamber 102, and an airflow sensor 93 installed at the position corresponding to the first chamber 101 on the elastic top cover 3, the aerosol-generating liquid in the porous liquid-absorbing 91 is unlikely to flow into the airflow sensor 93. Secondly, when not in use, i.e., in the first state, the air-blocking block 4 extends into the air outlet groove 33 to prevent the airflow sensor 93 from communicating with the mist outlet 21, thus preventing condensate and flowing aerosol from flowing into the airflow sensor 93. The air outlet groove 33 is opened automatically by the temperature sensor 5 when the user inhales. Therefore, aerosol, condensate, and leaked aerosol-generating liquid are effectively prevented from flowing into the airflow sensor 93, thereby improving the service life of the electronic atomizing device, which is also compact and low in cost.

[0077] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.

[0078] The present invention has been described above with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other situations without modification, are all within the protection scope of the present invention.
