Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an electronic product with a pressure relief structure. Background Technology
[0002] Electronic cigarettes are electronic products that use electronic heating to atomize e-liquid for users to inhale. They are a new type of tobacco alternative product in the category of daily necessities. Their core function is to convert electrical energy into heat energy to create an aerosol that can be inhaled, simulating the smoking experience of traditional cigarettes, but they usually do not contain the combustion products of traditional cigarettes.
[0003] Current e-cigarette products simply use sealing silicone to seal the microphone area, allowing it to function properly. However, this sealing silicone lacks pressure relief holes. During transportation, external environmental factors such as bumps and pressure, or accidental pressing of the USB charging port by the user when not in use, can easily disrupt the air pressure balance between the front and back of the microphone, creating an abnormal pressure difference. This unexpected pressure difference can directly trigger the microphone's activation mechanism, causing the e-cigarette to malfunction when not in use. This results in abnormal device operation, posing both safety hazards and potential unnecessary energy consumption. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides an electronic product with a pressure relief structure.
[0005] This utility model is achieved using the following technical solution: an electronic product with a pressure relief structure, characterized in that it includes an oil tank shell, a battery cell is fixedly connected to the inner wall of the oil tank shell, a button is provided inside the oil tank shell, a microphone silicone is fixedly connected to the bottom of the inner wall of the oil tank shell, an air adjustment knob is fixedly connected to the bottom of the microphone silicone, a microphone is fixedly connected to the inner wall of the microphone silicone, and a pressure relief hole is provided inside the microphone.
[0006] The above technical solution involves installing buttons, a battery cell, and silicone microphone housing inside the oil tank casing. When a user presses the button, the device starts, and airflow enters the device along a preset path via an air adjustment knob. The silicone microphone housing seals the gaps between itself and surrounding components. The microphone is installed on the inner wall of the silicone microphone housing, with a pressure relief hole inside. During equipment transportation or under abnormal conditions, unexpected pressure fluctuations may occur inside the device, creating an abnormal pressure difference between the front and back of the microphone. The pressure relief hole quickly connects the spaces on both sides of the microphone, allowing the pressure to rapidly balance through the tiny aperture, preventing abnormal pressure differences from triggering the microphone's start signal. This effectively prevents abnormal equipment operation, reduces safety hazards, and minimizes unnecessary energy consumption.
[0007] As a further improvement to the above solution, a sealing silicone is fixedly connected to the inner wall of the microphone silicone, and an oil tank base is fixedly connected to the bottom of the inner wall of the microphone silicone.
[0008] As a further improvement to the above solution, an oil-absorbing cotton base is fixedly connected to the top of the oil tank base, an oil tank bracket is fixedly connected to the top of the oil-absorbing cotton base, and a lower seal of the oil tank is fixedly connected to the top of the oil tank bracket.
[0009] As a further improvement to the above solution, an oil tank is fixedly connected to the top of the lower seal of the oil tank, the oil tank is fixedly connected to the inner wall of the outer shell of the oil tank, a heating wire seat is fixedly connected to the inner wall of the lower seal of the oil tank, and a heating core is fixedly connected to the top of the heating wire seat.
[0010] As a further improvement to the above solution, a heating wire sleeve is fixedly connected to the outer wall of the heating core, and an oil-blocking silicone is fixedly connected to the end of the heating wire sleeve away from the heating core.
[0011] As a further improvement to the above solution, an oil-absorbing cotton is fixedly connected to the end of the oil-separating silicone away from the heating wire sleeve, and an oil-absorbing cotton is fixedly connected to the heating wire sleeve at the end of the oil-separating silicone away from the oil-separating silicone.
[0012] As a further improvement to the above solution, the heating wire is fixedly connected to the top of the inner wall of the oil tank, the top of the oil tank is fixedly connected to the oil tank, and a suction nozzle is snapped onto the top of the oil tank.
[0013] Through the above technical solution, the sealing silicone seals the gap between the microphone silicone and the surrounding components, while the oil tank base and oil tank bracket provide stable support for the oil tank. The oil-absorbing cotton on the base can prevent e-liquid from leaking from the bottom. At the same time, the sealing of the oil tank is ensured by the bottom sealing and the sealing of the heating wire, which prevents e-liquid leakage and reduces energy consumption.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This invention incorporates a button, battery cell, and microphone silicone inside the oil tank casing. When a user presses the button, the device operates, and airflow enters the device along a preset path via an air adjustment knob. The microphone silicone seals the gaps between itself and surrounding components. The microphone is housed within the silicone casing, and a pressure relief hole is located inside. During transport or under abnormal conditions, unexpected pressure fluctuations may occur inside the device, creating an abnormal pressure difference between the front and back of the microphone. The pressure relief hole quickly connects the spaces on both sides of the microphone, allowing the pressure to rapidly balance through the tiny aperture. This prevents the abnormal pressure difference from triggering the microphone's start signal, effectively preventing abnormal equipment operation, reducing safety hazards, and minimizing unnecessary energy consumption.
[0016] This invention uses sealing silicone to seal the gap between the microphone silicone and surrounding components. The oil tank base and oil tank bracket provide stable support for the oil tank. The oil-absorbing cotton on the base can prevent e-liquid from leaking from the bottom. At the same time, the bottom seal of the oil tank and the top seal of the heating wire ensure the airtightness of the oil tank, prevent e-liquid leakage, and reduce energy consumption.

[0030] The inner wall of the microphone silicone 4 is fixedly connected with a sealing silicone 8, and the bottom of the inner wall of the microphone silicone 4 is fixedly connected with an oil tank base 9.
[0031] The top of the oil tank base 9 is fixedly connected to the base oil absorbent cotton 10, the top of the base oil absorbent cotton 10 is fixedly connected to the oil tank bracket 11, and the top of the oil tank bracket 11 is fixedly connected to the oil tank lower seal 12.
[0032] An oil tank 13 is fixedly connected to the top of the lower seal 12 of the oil tank. The oil tank 13 is fixedly connected to the inner wall of the outer shell 1 of the oil tank. A heating wire seat 14 is fixedly connected to the inner wall of the lower seal 12 of the oil tank. A heating core 15 is fixedly connected to the top of the heating wire seat 14.
[0033] A heating wire sheath 16 is fixedly connected to the outer wall of the heating core 15, and an oil-proof silicone 17 is fixedly connected to the end of the heating wire sheath 16 away from the heating core 15.
[0034] An oil-absorbing cotton 18 is fixedly connected to the end of the oil-separating silicone 17 away from the heating wire sleeve 16, and an oil-absorbing cotton 19 is fixedly connected to the end of the oil-absorbing cotton 18 away from the oil-separating silicone 17.
[0035] The heating wire upper filament 19 is fixedly connected to the top of the inner wall of the oil tank 13. The top of the oil tank 13 is fixedly connected to the oil tank upper filament 20, and the top of the oil tank upper filament 20 is snapped with a suction nozzle 21.
[0036] The implementation principle of an electronic product with a pressure relief structure in this application embodiment is as follows: A button 3, a battery cell 2, and a microphone silicone 4 are installed inside the oil tank casing 1. When a person presses the button 3, the device operates, and airflow enters the device along a preset path via the air adjustment knob 5. The gaps between the microphone silicone 4 and surrounding components are sealed. A microphone 6 is installed on the inner wall of the microphone silicone 4, and a pressure relief hole 7 is opened inside the microphone 6. During device transportation or under abnormal conditions, unexpected air pressure fluctuations may occur inside the device, causing an abnormal air pressure difference between the front and back of the microphone 6. At this time, the pressure relief hole 7 will quickly connect the spaces on both sides of the microphone 6, allowing airflow to pass through. The pressure is quickly balanced through a tiny aperture, preventing abnormal pressure differences from triggering the start signal of microphone 6, thus effectively preventing abnormal equipment operation, reducing safety hazards, and minimizing unnecessary energy consumption. When the user inhales through nozzle 21, the airflow enters the equipment through the air adjustment knob 5 along a preset path. It first passes through the air passage structure of the oil tank 20 and enters the air passage space inside the oil tank 13. This airflow process breaks the air pressure balance around microphone 7, creating a stable and effective air pressure difference on both sides of microphone 7. Since microphone 7 is the core control component for equipment startup, it can accurately sense this pressure difference signal, thereby triggering the starter motor. The sealing silicone 8 seals the gap between the microphone silicone 4 and the surrounding components. The oil tank base 9 and oil tank bracket 11 provide stable support for the oil tank 13. The base absorbent cotton 10 prevents e-liquid leakage. At this time, the battery cell 2, as the power supply core, immediately outputs electrical energy to the heating core 15. The heating wire holder 14 is fixed at the bottom of the heating core 15 and is also fixed to the inner wall of the lower seal 12 of the oil tank. When the heating core 15 is powered on, it heats up rapidly, and its heat is transferred to the e-liquid in the oil tank 13. At this time, the e-liquid in the oil tank 13 is conducted upward through the capillary action of the absorbent cotton 18 and further transported to the heating core 13 through the heating wire sleeve cotton 16. In the heating zone 5, the e-liquid is atomized under the high temperature of the heating core 15, forming an inhalable aerosol. The aerosol continues to flow upward along the airway, passing through the airway channel of the heating wire upper seal 19 and the flow guiding structure of the oil tank upper seal 20, and is finally inhaled by the user from the mouthpiece 21. During this process, the oil-separating silicone 17 can effectively prevent the e-liquid from leaking into the non-atomized area. The oil tank lower seal 12 and the heating wire upper seal 19 ensure the sealing of the bottom of the oil tank 13, preventing e-liquid leakage and ensuring that the e-liquid is efficiently conducted along the designed path. Since the mouthpiece 21 and the oil tank upper seal 20 are in a snap-fit connection, the mouthpiece 21 can be replaced.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
