Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of electronic cigarette microphone, concretely relates to an electronic cigarette microphone with protection structure. BACKGROUND

[0002] In recent years, electronic cigarettes as a substitute for traditional tobacco have gained wide attention and rapid development worldwide. With consumers increasingly valuing health and quality of life, electronic cigarettes have attracted a large number of traditional smokers and consumer groups pursuing fashion and convenience due to their relatively low tar content and adjustable nicotine content. In the structure of electronic cigarettes, the electronic cigarette microphone plays a crucial role as the "breathing switch" of the electronic cigarette. When a user inhales the electronic cigarette, the microphone can sensitively detect changes in airflow, thereby triggering the atomizer to work and converting the oil into smoke for inhalation. The performance of the microphone directly affects the user experience of the electronic cigarette. However, many electronic cigarette microphones on the market have relatively weak protection measures, thereby shortening the service life of the electronic cigarette.

[0003] A patent with publication number CN219845037U discloses a microphone head protection structure and an electronic cigarette microphone. The device protects the microphone through multiple protection structures, preventing aerosol particles from eroding the circuit board and preventing too much oil from being sucked into the microphone body. This greatly improves the service life of the microphone body. However, the device accumulates the dust screen, coating, and filtering structure in the second protection structure at the position of the microphone air inlet hole, which increases the resistance when the microphone inhales, affecting the overall use.

[0004] Therefore, the utility model is proposed. UTILITY MODEL CONTENT

The partition plate is fixedly connected with an adsorption layer. The end of the microphone body away from the air inlet hole is fixedly connected with a breathable film. The outer wall of the microphone body is sprayed with a protective coating.

[0008] Optionally, a flow guide hopper is fixedly connected in the microphone body between the baffle and the air permeable membrane, and the flow guide hopper is a hollow structure with openings at two ends.

[0009] Optionally, the flow guide hopper is a funnel-shaped structure with a cross-sectional area gradually decreasing from the baffle to the air permeable membrane.

[0010] Optionally, the air permeable membrane is an air permeable membrane made of PP material.

[0011] Optionally, the adsorption layer is an electrostatic adsorption layer.

[0030] The utility model will now be described in further detail in conjunction with the drawings.

[0031] Please refer to Figures 1-5 It is shown that in the present embodiment, an electronic cigarette microphone with a protective structure is provided, which comprises a microphone body 1 and a filter screen 2 arranged at the air inlet hole of the microphone body 1, a partition 8 fixedly connected inside the microphone body 1 adjacent to the filter screen 2, the partition 8 forming a spiral channel 7 inside the microphone body 1, the partition 8 being fixedly connected with an adsorption layer 11, the microphone body 1 being fixedly connected with a breathable film 6 at one end away from the air inlet hole, and the outer wall of the microphone body 1 being sprayed with a protective coating 4.

[0032] Specifically, when the user smokes the electronic cigarette, air first enters through the air inlet hole, the filter screen 2 at the air inlet hole intercepts larger particles of dust, impurities and the like in the air, and preliminarily filters the entering air. The preliminarily filtered air enters the spiral-shaped channel 7 formed by the partition plate 8, which prolongs the flow path of the air, so that the air has more sufficient contact time and area with the adsorption layer 11. The adsorption layer 11 can adsorb the residual small particles and impurities in the air, further purifying the air. The air treated by the adsorption layer 11 can better contact the diaphragm in the microphone body 1. At the same time, the gas permeable membrane 6 allows gas to pass through and can block possible liquid or other contaminants, ensuring the cleanliness and dryness of the internal circuit board and other structures of the microphone. The protective coating 4 on the outer wall of the microphone body 1 protects the microphone body 1 from moisture, oil stains and other environmental factors that may cause erosion or damage to the microphone body 1. The double filtration of the filter screen 2 and the adsorption layer 11 can significantly reduce impurities and pollutants entering the interior of the microphone, protect sensitive components inside the microphone, improve the reliability and stability of the microphone, and prolong its service life. At the same time, the design of the spiral-shaped channel 7 makes full use of the space, improves the efficiency of air purification, enhances the filtering and adsorption capacity of impurities of different sizes, and provides more comprehensive protection for the microphone by the gas permeable membrane 6 and the protective coating 4, avoiding the entry of moisture and preventing internal circuit board short circuit and corrosion, thereby improving the environmental adaptability of the microphone.

[0033] It should be noted that in the present embodiment, the electronic cigarette microphone is usually a capacitive sensor, which has a diaphragm and a fixed plate, and a capacitor is formed between the two. In the static state, the diaphragm and the fixed plate maintain a certain distance, and the capacitance is fixed. When the user inhales, the airflow enters through the air inlet hole of the microphone, and the airflow causes the diaphragm to deform slightly, changing the distance between the diaphragm and the fixed plate. According to the calculation formula of the capacitor, it can be known that the change of the distance will cause the change of the capacitor. The working principle of the electronic cigarette microphone and the connection relationship with other accessories can also be referred to the disclosure documents with patent publication numbers CN219845037U, CN217906325 and CN216088838U, which will not be described here.

[0035] In the embodiment, as shown in Figure 2 , Figure 3 and Figure 4 , the air permeable film 6 is a PP material air permeable film, specifically, the PP material air permeable film 6 has relatively low cost, good chemical stability and certain mechanical strength, can effectively prevent liquid from penetrating into the microphone, ensure the dryness and cleanliness of the microphone, and ensure the safety of the circuit board.

[0036] In the embodiment, as shown in Figure 5 , the adsorption layer 11 is preferably an electrostatic adsorption layer, specifically, the electrostatic adsorption layer can effectively capture fine impurities such as fine dust and part of aerosol that may escape the filter screen 2, further improve the purification effect of the entering air, and protect the sensitive components in the microphone from the influence of fine impurities, compared with simple physical filtration, electrostatic adsorption has better removal effect on some fine impurities that are difficult to pass through physical barriers, improves the overall performance of the microphone, and needs to be explained that the material of the electrostatic adsorption layer can be PET, PTFE, PP, etc.

[0037] In the embodiment, as shown in Figure 2 , Figure 3 and Figure 4 , the protective coating 4 is preferably a fluorocarbon polymer protective coating, specifically, this coating can make water droplets form water beads on the surface and roll off, prevent moisture from penetrating into the microphone, and effectively prevent water vapor from adhering and penetrating on the surface of the microphone.

[0038] In the embodiment, as shown in Figure 1 , Figure 3 , Figure 4 and Figure 5 , the microphone body 1 is provided with a drain groove 12 communicating with the channel 7 at the bottom, and the microphone body 1 is detachably connected with a sealing plug 5 sealing the drain groove 12, specifically, after the microphone is used for a period of time, part of the impurities may accumulate in the spiral channel 7, the adsorption layer 11 and other parts, when the sealing plug 5 is opened, these impurities can be discharged through the drain groove 12 communicating with the channel 7, ensuring the long-term stable operation of the microphone and reducing the performance degradation caused by impurity accumulation.

[0039] In the embodiment, as shown in Figure 1、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown in the figure, the microphone body 1 is externally sleeved with a sealing ring 3, and the microphone body 1 is internally embedded with a mounting groove 10 for mounting the sealing ring 3, specifically, the sealing ring 3 can effectively prevent external pollutants from entering the microphone from the gap, improve the overall sealing performance, further enhance the protection effect, and ensure the reliability of the microphone in different use environments.

[0041] When the user smokes the electronic cigarette, the air first enters through the air inlet hole, and the filter screen 2 at the air inlet hole can intercept the larger particles of dust, impurities and the like in the air, and preliminarily filter the entering air. The air after preliminary filtration enters the spiral channel 7 formed by the partition plate 8, which prolongs the flow path of the air, so that the air has more sufficient contact time and area with the adsorption layer 11. The adsorption layer 11 can adsorb the residual small particles and impurities in the air, further purify the air, and the air treated by the adsorption layer 11 can better contact the diaphragm in the microphone body 1. At the same time, the gas permeable film 6 allows gas to pass through, can block possible liquid or other pollutants, ensures the cleanliness and dryness of the internal circuit board and other structures of the microphone, the protective coating 4 on the outer wall of the microphone body 1 plays a role in protecting the microphone body 1, preventing water vapor, oil stains and the like in the external environment from eroding or damaging the microphone body 1. The double filtration of the filter screen 2 and the adsorption layer 11 can significantly reduce the impurities and pollutants entering the interior of the microphone, protect the sensitive components in the interior of the microphone, improve the reliability and stability of the microphone, and prolong the service life thereof. At the same time, the design of the spiral channel 7 fully utilizes the space, improves the air purification efficiency, enhances the filtration and adsorption capacity of impurities of different sizes, and the gas permeable film 6 and the protective coating 4 provide more comprehensive protection for the microphone, avoid water vapor and the like from entering, prevent internal circuit board short circuit and corrosion, and improve the environmental adaptability of the microphone.
