Description

Oil-proof structure, trigger module and electronic atomization device Technical Field

[0001] The present application relates to the field of electronic atomization devices, and in particular to an oil-proof structure, a trigger module, and an electronic atomization device. Background Art

[0002] As electronic atomizer technology advances, the oil storage capacity of electronic atomizers gradually increases, and the number of puffs also increases accordingly. During use, internal condensation will accumulate over time and flow back to the microphone head on the PCB board.

[0003] The microphone has a thin film inside that is slightly deformed by air pressure during use, generating an electrical signal to activate the microphone. During use, smoke generated by the aerosol matrix enters the microphone through the airway. Smoke adhering to the film may corrode it, causing the microphone to automatically activate, delay operation, or even stop working.

[0004] Conventional technology typically adds an oil-proof film to the top of the microphone to block aerosol matrix leaking into the microphone before atomization and condensate flowing back after atomization. However, this protection is incomplete and adverse effects may still occur. Currently, silicon-marked microphones are being used to replace traditional microphones. Silicon-marked microphones use a silicon crystal sensor instead of a thin film. Silicon crystal has properties similar to glass and is resistant to corrosion and high temperatures. Even a small amount of aerosol matrix adhering to the interior will not affect the activation function.

[0005] However, after long-term use, as the mass of the adhering aerosol base increases, it will still have a certain adverse effect on the normal operation of the silicone microphone head, resulting in adverse phenomena during the use of the electronic atomization device. Utility Model Content

[0006] Based on this, it is necessary to provide an oil-proof structure, a trigger module and an electronic atomization device to address the problem that the aerosol matrix adheres to the silicone microphone head and affects the normal operation of the silicone microphone head.

[0007] In a first aspect, the present application provides an oil-proof structure, which adopts the following technical solution:

[0008] An oil-proof structure includes a base plate and a protective cover. The base plate is used for mounting a silicon-marked microphone. The protective cover is mounted on the base plate and is used to cover the periphery of the silicon-marked microphone. An installation space for accommodating the silicon-marked microphone is enclosed between the protective cover and the base plate, and the installation space is isolated from the outside world.

[0009] In one embodiment, the protective cover includes a cover body, which is mounted on the substrate and used to cover the periphery of the silicon mark microphone. The installation space is enclosed between the cover body and the substrate. The cover body includes a detection hole, which passes through a side wall of the cover body.

[0010] In one embodiment, the protective cover further includes a first oil-proof component, which is mounted on the cover body and can block the detection hole.

[0011] In one embodiment, the first oil-proof component is made of a flexible material and is configured into a membrane-like structure.

[0012] In one embodiment, the oil-proof structure further includes a second oil-proof component, which is disposed in the installation space and is used to cover the periphery of the silicone microphone head.

[0013] In one embodiment, the second oil-proof component is made of a flexible material and is configured into a membrane-like structure.

[0014] In a second aspect, the present application provides a trigger module, which adopts the following technical solution:

[0015] A trigger module is used to trigger the control module of an electronic atomization device, including a silicon mark microphone and the above-mentioned oil-proof structure. The silicon mark microphone is used to detect airflow changes in the electronic atomization device; the oil-proof structure is arranged around the periphery of the silicon mark microphone.

[0016] In a third aspect, the present application provides an electronic atomization device, which adopts the following technical solution:

[0017] An electronic atomization device includes a shell, a control module and the above-mentioned trigger module, wherein the shell has a built-in accommodating cavity; the control module is used to control the operating state of the electronic atomization device; the trigger module is installed in the accommodating cavity, and a signal connection is established between the trigger module and the control module.

[0018] In one embodiment, the electronic atomization device further includes an atomization module disposed in the accommodating cavity, the atomization module is used to excite smoke, and a signal connection is established between the atomization module and the control module.

[0019] In one embodiment, the electronic atomization device further includes a power supply module disposed in the accommodating cavity, and the power supply module is electrically connected to the trigger module, the control module and the atomization module respectively for power supply.

[0020] The above-mentioned oil-proof structure sets the silicon mark microphone head in the installation space, and the protective cover is arranged on the outside of the silicon mark microphone head to isolate the condensate, so that the aerosol matrix leaked to the silicon mark microphone head before the electronic atomization device is atomized and the condensate generated after a period of use is not easy to enter the space where the silicon mark microphone head is located, thereby reducing the situation where the silicon mark microphone head is adhered to the aerosol matrix or condensate and malfunctions, thereby reducing the failure rate of the electronic atomization device and improving the user experience.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features.

[0032] The microphone in an electronic atomizer is a miniature electroacoustic device used in electronic atomizers. Its primary function is to receive the user's inhalation signal to control the device's start and stop. It uses an airflow sensor (i.e., the microphone) to control the on / off state. When the "puff" action is detected, the microphone responds accordingly (generating a trigger signal) and triggers the control circuit, starting the atomizer, thereby heating the aerosol matrix to form an aerosol.

[0033] The microphone of an electronic atomization device usually includes a microphone body and a corresponding control chip. These control chips can integrate multiple functional circuits, such as airflow sensor circuit, output power management circuit, charging management circuit, status indication circuit and protection circuit, etc. The application and development of the microphone of the electronic atomization device in the market has also brought new applications and developments to the microphone chips that were originally common in microphones.

[0034] With the improvement and upgrading of electronic atomizer devices, traditional disposable electronic atomizer devices are gradually being eliminated from the market. New electronic atomizer devices are also designed with increasingly larger oil contents and more puffs. After repeated puffs from an electronic atomizer device, a large amount of condensation will accumulate inside. However, traditional microphones have a thin membrane inside. During use, changes in air pressure cause the membrane to slightly deform, generating an electrical signal to activate the microphone. During the use of electronic atomizer devices, the mist generated by the atomization of the aerosol matrix enters the microphone through the airway. The smoke adheres to the membrane and may corrode it, causing traditional microphones to start automatically, delay operation, or even stop working.

[0035] To reduce the risk of aerosol substrates corroding the microphone film, which could affect normal operation, silicon-marked microphones have been adopted to replace traditional microphones. Unlike traditional microphones, silicon-marked microphones use a silicon crystal sensor, replacing the thin film in traditional microphones. Silicon crystals have physical properties similar to glass, making them resistant to aerosol substrate corrosion and high temperatures. Even a small amount of aerosol substrate adhering to the surface during use is unlikely to affect normal operation.

[0036] However, the silicon-labeled microphone heads commonly used in electronic atomization devices are typically single silicon-labeled microphone heads, without effective oil-proofing measures. Electronic atomization devices heat up to produce aerosol and condensate. The aerosol matrix produced before atomization and the small amount of condensate produced after atomization can still drip or adhere to the silicon crystals of the silicon-labeled microphone head, affecting the normal function of the silicon-labeled microphone head, which in turn increases the failure rate of the electronic atomization device and affects the user experience.

[0037] Therefore, there is an urgent need to design a protective structure for silicon-marked microphone heads to solve the problem that after repeated use of the electronic atomizing device, a large amount of aerosol matrix or condensate adheres to the silicon-marked microphone head, resulting in an increased failure rate of the electronic atomizing device and affecting the user experience.

[0038] The embodiments of the present application are further described in detail below with reference to Figures 1-3.

[0039] Referring to Figures 1 to 3, one embodiment of the present application provides an oil-proof structure 12 for isolating a silicon label microphone 11 from aerosol substrates and condensate to reduce erosion and impact of the aerosol substrates or condensate on the silicon label microphone 11. Specifically, the oil-proof structure 12 includes a base plate 121 and a protective cover 122. The base plate 121 is used to mount the silicon label microphone 11. The protective cover 122 is mounted on the base plate 121 and covers the periphery of the silicon label microphone 11. The protective cover 122 is fixedly connected to the base plate 121.

[0040] In the embodiment of the present application, the substrate 121 is specifically a PCB board, and the silicon label microphone 11 can be mounted on the substrate 121 by patch welding, thereby achieving a stable connection between the silicon label microphone 11 and the substrate 121. The protective cover 122 can also be connected to the substrate 121 by welding, and an installation space for accommodating the silicon label microphone 11 is formed between the protective cover 122 and the substrate 121. The installation space is isolated from the outside world, which can effectively reduce the aerosol matrix and condensation generated during the placement or use of the electronic atomization device from entering the installation space and causing corrosion to the silicon label microphone 11.

[0041] Referring to Figure 1, Figure 1 shows a schematic diagram of the three-dimensional structure of the oil-proof structure 12 in an embodiment of the present application. The protective cover 122 includes a cover body 1221. In the embodiment of the present application, the cover body 1221 is constructed as a cylindrical structure with one end open and the other end closed. The structural design of the cover body 1221 is consistent with the shape of a traditional microphone, which helps to switch with the traditional microphone while ensuring that the original product structure remains unchanged, effectively reducing the corresponding replacement cost.

[0042] In other embodiments, the outer shape of the cover 1221 may also be modified to reflect changes in the original product structure. For example, if the original product's traditional microphone is square, the cover 1221 used to replace it may also be configured in a corresponding square shape. It is understood that in other embodiments, as the shape of the traditional microphone changes, the outer shape of the cover 1221 may also be modified to reflect changes in the shape of the traditional microphone, allowing it to be configured in any other shape.

[0043] Specifically, the open end of the cover body 1221 is welded to the above-mentioned substrate 121, and the closed end is upward, so as to receive the aerosol matrix and condensate dripping on the cover body 1221, so as to reduce the situation where the condensate drips directly onto the silicon mark microphone 11 and affects the normal operation of the silicon mark microphone 11.

[0044] Furthermore, in some embodiments, the cover body 1221 also includes a guide surface, which is located on the side of the cover body 1221 close to the closed end. The guide surface is arranged along the circumference of the cover body 1221 and smoothly transitions the top surface and side surface of the cover body 1221, so that the aerosol matrix and condensate dripping on the cover body 1221 can flow around the cover body 1221 under the guiding action of the guide surface, thereby reducing the accumulation of condensate on the top surface of the cover body 1221 and affecting the silicon mark microphone 11 to detect the internal air pressure fluctuations of the electronic atomization device, which helps to improve the accuracy of the detection results of the silicon mark microphone 11, thereby reducing the failure rate of the electronic atomization device.

[0045] As shown in Figure 2, Figure 2 shows an exploded view of the oil-proof structure 12 in an embodiment of the present application. In the embodiment of the present application, the cover body 1221 is made of metal with a certain structural strength, which helps to maintain the stability of the external structure of the cover body 1221 and reduce the situation where the internal air pressure of the installation space changes after the cover body 1221 receives a certain amount of condensate, thereby affecting the detection accuracy of the silicon mark microphone 11.

[0046] Therefore, in order to enable the silicon mark microphone 11 to still detect the changes in air pressure inside the electronic atomization device in the cover body 1221 of fixed shape, in an embodiment of the present application, a detection hole 3 is provided on the cover body 1221. The detection hole 3 passes through any side wall of the cover body 1221 to connect to the outside world, so as to reduce the impact of the setting of the cover body 1221 on the accuracy and timeliness of the detection results of the silicon mark microphone 11.

[0047] In the embodiment of the present application, only the detection hole 3 passing through the top wall of the cover body 1221 is illustrated as an example. In some other embodiments, the detection hole 3 can also be set on the side wall of the cover body 1221. As long as a slight synchronization of airflow and air pressure between the installation space of the cover body 1221 and the external environment can be achieved, the specific setting position is not limited.

[0048] Furthermore, in order to reduce the impact of setting the detection hole 3 on the overall airtightness of the installation space, in some embodiments, the protective cover 122 also includes a first oil-proof component 1222 installed on the cover body 1221, and the first oil-proof component 1222 can block the above-mentioned detection hole 3 to achieve isolation of the condensate.

[0049] In the embodiment of the present application, the first oil-repellent member 1222 can be detachably connected to the housing 1221 by bonding, so that the first oil-repellent member 1222 can be removed and replaced during subsequent maintenance, thereby helping to maintain a clean environment within the electronic atomizer device. Liquid glue or double-sided tape can be used for bonding, with mesh tape, which is less likely to leave marks, being preferred.

[0050] Continuing to refer to Figure 2, in some other embodiments, the oil-proof structure 12 further includes a second oil-proof component 123. The second oil-proof component 123 is arranged in the installation space and is attached to the detection hole 111 of the silicon label microphone 11 to block the detection hole 111 of the silicon label microphone 11 to further reduce the possibility of aerosol matrix and condensate entering the silicon label microphone 11.

[0051] In this embodiment of the present application, the first and second oil-repellent members 1222 and 123 can be made of the same material or different materials, as long as they are both made of flexible materials. Furthermore, to minimize the impact of the first and second oil-repellent members 1222 and 123 on the detection sensitivity of the silicon marking microphone 11, the first and second oil-repellent members 1222 and 123 in this embodiment of the present application are both constructed as membranes with minimal thickness.

[0052] It is worth noting that in any of the above embodiments, the selected silicone microphone head 11 can still perform normal air pressure detection work even without the protective cover 122 and the second oil-proof part 123. However, after long-term use, it may be affected by the aerosol matrix and condensate and may cause slight detection deviation.

[0053] In combination with FIG. 1 and FIG. 2 , in some embodiments, the present application further provides a trigger module 1 , which is used to trigger a control module of the electronic atomization device, thereby controlling the electronic atomization device to switch between an on state and an off state.

[0054] Specifically, the trigger module 1 includes a silicon mark microphone 11 and the oil-proof structure 12 shown in any of the above embodiments. The silicon mark microphone 11 is used to detect changes in the air flow pressure inside the electronic atomization device, and then generate a corresponding trigger signal to drive the control module to control the electronic atomization device to switch between the start state and the shutdown state.

[0055] The oil-proof structure 12 is positioned around the outer periphery of the silicon-marked microphone 11. Its protective cover 122 and second oil-proof member 123 respectively protect the entire structure of the silicon-marked microphone 11 and the detection hole 111 from oil. This dual-layer oil-proofing effect significantly improves the reliability of the trigger module 1 and reduces the risk of malfunctions caused by aerosol matrix or condensate accumulation during use of the electronic atomizer.

[0056] In conjunction with Figures 1 to 3, in some embodiments, the present application further provides an electronic atomization device, which includes a housing 6, a control module (not shown), and the aforementioned trigger module 1. The housing 6 has a built-in accommodating chamber 61, and the control module and trigger module 1 are both installed in the accommodating chamber 61. The trigger module 1 and the control module are signal-connected, so that the control module can control the opening and closing of the electronic atomization device after the trigger module 1 generates a corresponding trigger signal.

[0057] Referring to FIG. 3 , in some embodiments, the electronic atomization device further includes an atomization module 4 disposed within a housing chamber 61 . The atomization module 4 is signal-connected to a control module to stimulate the aerosol matrix to produce harmless smoke for inhalation by the user. Specifically, the atomization module 4 includes an atomization core unit 41 and an oil storage unit 42 . The oil storage unit 42 is configured to supply oil to the atomization core unit 41 . The oil storage unit 42 is sheathed around the outer circumference of the atomization core unit 41 , i.e., the atomization core unit 41 is located within the inner cavity of the oil storage unit 42 . The atomization core unit 41 and the oil storage unit 42 are integrated and combined to facilitate unified assembly.

[0058] In this embodiment, the oil storage unit 42 is sleeved around the outer circumference of the atomizer core unit 41. This not only ensures sufficient oil supply to the atomizer core unit 41, but also creates a relatively compact integrated structure that takes up little space. During actual assembly, the atomizer core unit 41 and the oil storage unit 42 can also assist in positioning each other, making the sleeve installation more convenient.

[0059] Continuing to refer to FIG3 , in some embodiments, the oil storage unit 42 includes an oil tank 421, which is used to place the atomizer core unit 41, that is, the atomizer core unit 41 is arranged in the inner cavity of the oil tank 421. In some other embodiments, the oil storage unit 42 also includes oil storage cotton 422, which is sleeved on the atomizer core unit 41 and filled in the oil tank 421. The oil storage cotton 422 can make the oil in the oil tank 421 penetrate more evenly, and can lock the oil and reduce oil leakage. In some other embodiments, the oil storage unit 42 also includes oil-absorbing cotton 423, which is arranged at the top of the shell 6, and the oil-absorbing cotton 423 can absorb the condensate generated when the atomizer core unit 41 is atomized.

[0060] In some embodiments, the electronic atomization device further includes a power module 5, which is electrically connected to the trigger module 1, control module, and atomization module 4, respectively, to supply power to the trigger module 1, control module, and atomization module 4. After the user draws on the electronic atomization device, the trigger module 1 can promptly sense the changes in the airflow and pressure within the accommodating chamber 61 and issue a corresponding trigger signal. After receiving the corresponding trigger signal, the control module controls the electronic atomization device to switch to an activated state, thereby controlling the atomization module 4 to activate and stimulate the aerosol matrix to generate smoke for inhalation.

[0061] In some other embodiments, the electronic atomization device further includes a nozzle 7 mounted on the housing 6. The nozzle 7 is connected to the housing 6 in a detachable manner, including but not limited to a snap-on connection, a threaded connection, or a magnetic connection, to facilitate the user to replace the nozzle 7 at any time, thereby extending the service life of the electronic atomization device. In the embodiment of the present application, the housing 6 is constructed as a tubular structure, and the nozzle 7 is connected to one end of the housing 6 and communicates with the accommodating cavity 61.

[0062] Furthermore, in some other embodiments, the electronic atomization device further includes a blocking member 8 disposed on the suction nozzle 7. The blocking member 8 is detachably connected to the suction nozzle 7. When the electronic atomization device is not in use, the blocking member 8 blocks the suction nozzle 7 to reduce the entry of foreign matter into the atomizer core unit 41 through the suction nozzle 7. When the electronic atomization device is in use, the blocking member 8 can be removed.

[0063] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
