Description

TECHNICAL FIELD

[0001] The utility model relates to gas vibration technical field, especially relate to a atomizer microphone device and atomizer. BACKGROUND

[0002] In the atomizer microphone of prior art, as the detection method of smoking action, a capacitive airflow sensor is usually used as the detection device, and the diaphragm plays a key role in the capacitive airflow sensor. The diaphragm is an easily deformable carrier such as PPS film or inorganic film, which is fixed in the structural member by adhesion. The diaphragm needs to be tightly fixed with a certain tension. When the diaphragm is wrinkled or damaged, which affects the cleanliness or surface tension of the diaphragm, the stress and deformation effect of the diaphragm changing with airflow are no longer stable. In a non-working state, the electronic chip may be misjudged as a working state, causing the atomizer to start automatically, for example:

[0003] Patent No. CN116671667, patent name: a rear back electrode type atomizer microphone detection method, detects the microphone capacitor of the rear back electrode type atomizer microphone; the rear back electrode type atomizer microphone includes a back electrode plate and a copper ring film, the copper ring film is located outside the back electrode plate, and forms a parallel plate capacitor opposite to the back electrode plate; when the user's mouth suction action occurs, the parallel plate capacitor decreases with the increasing distance between the copper ring film and the back electrode plate, to generate a microphone capacitor with reduced capacitance; according to the capacitance reduction state of the microphone capacitor with reduced capacitance, the atomizer is controlled to work.

[0004] However, through actual use and market research, it is found that the working conditions of the atomizer in the prior art are complex. The atomizer is used to heat the tobacco tar to produce smoke atomization. In order to realize various flavors and levels of smoke, various chemical additives need to be used for adjustment. After various substances are heated and atomized, they will be back-penetrated into the atomizer in the form of mist. When the mist contacts the diaphragm, it will accelerate the aging of the surface tension of the diaphragm. This kind of aging cannot be avoided, and the surface tension of the aged diaphragm becomes loose, which may cause the atomizer to start automatically, causing serious safety hazards. SUMMARY

[0005] In view of the above technical problems in the prior art, the utility model provides an atomizer microphone device, which comprises components, a flexible member and a shell arranged in sequence; the components are provided with a sensor; the flexible member is provided with an outer wall, an arc surface and a sensor, the outer wall supports the arc surface, the sensor is arranged close to the arc surface, and the sensor is arranged correspondingly to the sensor; the shell internally accommodates the components and the flexible member.

[0006] Specifically, the sensor is a Hall sensor, and the inductor is a magnetic bead arranged in a concentric shaft with the Hall sensor.

[0007] Specifically, the flexible member is a tubular structure with two open ends, and the arc surface is formed by thinning the wall surface at the center of the flexible member.

[0008] Specifically, the thickness of the outer wall is greater than the thickness of the arc surface, and the outer wall and the arc surface are integrally formed.

[0009] Specifically, the shell is a tubular structure with one open end, and the upper end of the shell is provided with an air inlet.

[0010] Specifically, the shell encapsulates the flexible member and the component into the microphone, the middle part of the microphone is supported by the outer wall of the flexible member, and the outer wall abuts against the shell and the component.

[0012] Specifically, the component includes a circuit board, and the circuit board is electrically connected with the sensor.

[0013] Specifically, it further comprises a dust screen, and the dust screen is arranged on the shell.

[0014] The utility model provides two aspects of a kind of atomizer, comprising:

[0015] Microphone module, the microphone module includes component, flexible member and shell sequentially arranged;The component is provided with sensor;The flexible member is provided with outer wall, arc surface and inductor, the outer wall supports the arc surface, the inductor is arranged closely to the arc surface, and the inductor is arranged correspondingly with the sensor;The shell internally accommodates the component and the flexible member;

[0016] Control module, for detecting the distance of the inductor away from the component according to the sensor, output airflow action signal, control the atomizer output smoke.

[0017] Compared with the prior art, the sensor adopts a Hall type as the detection mode of air flow. When the Hall type air flow sensor is applied in the atomizer, when the consumer inhales, the middle film of the arc surface is deformed away from the component, the magnetic beads of the sensor are driven away from the bottom component and the sensor by the deformation of the arc film. When it is away to a certain distance, that is, out of the detection range of the sensor, it is determined as a smoking action. The Hall type is adopted as the detection mode of air flow, which has high reliability, mature detection mode and long service life. The arc surface uses a silica gel film to replace the diaphragm, which is not easily affected by external environmental factors. Directly touching, soaking in tobacco oil and other operations will not affect the working state of the arc surface. BRIEF DESCRIPTION OF DRAWINGS

[0043] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the structure of the prior art pre-back electrode type atomizer microphone;

[0044] Figure 2 is a schematic diagram of the copper ring film deformation close to the back electrode plate in the prior art pre-back electrode type atomizer microphone; Figure 1 and Figure 2It is to be noted that in the prior art, the atomizer all adopts a front-mounted back electrode type microphone, and the structure of the front-mounted back electrode type atomizer microphone comprises, from outside to inside, a protective net 1, a shell 2, a back electrode plate 3, a gasket 4, a plastic ring 5, a copper ring film 6, and a PCB. Since the back electrode plate 3 is arranged outside the copper ring film 6, when a user performs a puffing action, the copper ring film 6 deforms along the airflow and moves close to the back electrode plate 3, and the parallel-plate capacitor formed between the copper ring film 6 and the back electrode plate 3 has a large capacitance value due to the small distance between the two. At this time, the electronic chip collects the signal of the large capacitance, judges the puffing action of the user according to the signal of the large capacitance, and opens the output control, so as to control the heating and atomization of the tobacco oil of the atomizer and output the smoke. However, when the cartridge leaks liquid to the surface of the microphone or the microphone is touched by hand, the capacitance value of the parallel-plate capacitor of the atomizer microphone will become large, and at this time, the electronic chip is difficult to determine which signal is the real and effective puffing signal, and the electronic chip may respond to the abnormal signal and start the output, causing self-starting.

[0045] Please refer to Figure 3 and Figure 4 , Figure 3 is a schematic diagram of the structure of a back-mounted back electrode type atomizer microphone in the prior art;

[0046] Figure 4 is a schematic diagram of the deformation of the copper ring film away from the back electrode plate in the back-mounted back electrode type atomizer microphone in the prior art; in this embodiment, unlike the front-mounted back electrode type atomizer microphone, the back-mounted back electrode type atomizer microphone also comprises a back electrode plate 3 and a copper ring film 6, but the copper ring film 6 is arranged outside the back electrode plate 3 and forms a parallel-plate capacitor opposite the back electrode plate 3; when the user performs a puffing action, the parallel-plate capacitor decreases with the increase of the distance between the copper ring film 6 and the back electrode plate 3, so as to generate a microphone capacitor with a reduced capacitance value, and the atomizer is controlled to work according to the state of the reduced capacitance value of the microphone capacitor. However, when the copper ring film 6 is wrinkled or damaged, which affects the surface cleanliness or surface tension, the change stress and deformation effect of the copper ring film 6 along with the airflow are no longer stable, and seriously, the electronic chip may be misjudged as being in a working state in a non-working state, resulting in self-starting of the atomizer.

[0048] To address the problems existing in the prior art, the present invention provides a nebulizer 100 microphone device 100, including a flexible member 10. The material of the flexible member 10 is not specifically limited in this invention; it can be silicone, polyurethane, thermoplastic elastomer, fluororubber, or polyimide film, all of which are protected by this invention. In this embodiment, silicone is preferred.

[0049] The shape of the flexible component 10 is not specifically limited in this invention. Its external shape can be cylindrical, cubic or polygonal, all of which are protected by this invention.

[0050] In this embodiment, the flexible component 10 is a circular silicone component. The flexible component 10 includes an outer wall 103 and an arc surface 101. The outer wall 103 serves as a fixed support. The silicone wall at the center of the flexible component 10 is thinned to form the arc surface 101. The thickness of the outer wall 103 is greater than the thickness of the arc surface 101. It is understood that the thickness of the arc surface 101 can be adjusted according to actual conditions to achieve deformation following airflow changes; no specific limitation is imposed.

[0051] In this embodiment, the arc surface 101 is made of silicone material to replace the copper ring film in the prior art, which has a longer service life and is preferably in the form of a thin film. The arc surface 101 can be divided into a first arc surface 1011, a second arc surface 1012, and a third arc surface 1013. The sensor 102 is fixed on the second arc surface 1012. The first arc surface 1011, the second arc surface 1012, and the third arc surface 1013 are connected in sequence, forming an inclined semi-arc shape when stationary. The inclined semi-arc design allows the airflow to be naturally guided to the lowest point (close to the second arc surface 1012), ensuring that the sensor 201 can efficiently detect changes in airflow. The lowest point of the arc surface 101 is close to the second arc surface 1012, which is the lowest point and exactly where the airflow converges. This arrangement can amplify the effect of airflow deformation on the sensor 102, increase the sensitivity of the sensor 201, and ensure higher detection accuracy. The first arc surface 1011 and the third arc surface 1013 are symmetrically arranged so that the stress of the entire arc surface 101 can be evenly distributed under the action of airflow or external force, avoiding uneven deformation or damage caused by excessive force on one side.

[0052] It can be understood that the inductor 102 is not limited in particular, and in the embodiment, the inductor 102 is a magnetic bead, which has a small volume and is arranged at the second arc surface 1012 and can conform to the second arc surface 1012. In other embodiments, as long as the inductor 102 can form a matched working relationship with the Hall sensor 201 and effectively sense the airflow change, the following inductors 102 can also be adapted: a permanent magnet, a magnetic composite material, a soft magnetic material, a conductive metal piece, a magnetic liquid, and a multi-pole magnet.

[0053] The atomizer 1000 microphone device 100 includes a component 20, and the shape of the component 20 is not limited in particular in the application. In the embodiment, the component 20 is a circular PCB board, which includes a sensor 201 and a circuit board. The sensor 201 is centrally attached to the circuit board, and the sensor 201 and the inductor 102 are coaxially arranged. The coaxial design ensures that the sensor 201 is always located at the center of the magnetic field or other signals generated by the inductor 102, so that the displacement change is directly reflected as a change in the detection signal, thereby improving the detection accuracy.

[0054] It can be understood that the type of the sensor 201 is not limited, as long as it can achieve the function of sensing the airflow change. In the embodiment, the sensor 201 is a Hall sensor 201, which has high reliability, a mature detection method, and a long service life. In other embodiments, the sensor 201 can be a magnetoresistive sensor 201, a linear Hall sensor 201, a switching Hall sensor 201, a bipolar Hall sensor 201, and a magnetic induction coil, and the type is not limited in particular.

[0055] The atomizer 1000 microphone device 100 includes a housing 30, and the shape of the housing 30 is not limited in particular in the application. The external shape can be cylindrical, square, or polygonal, which are all within the protection scope of the application.

[0056] The housing 30 has a design structure with an accommodation space inside. The housing 30 includes an air hole 301. In the embodiment, the housing 30 is a cylindrical structure, the middle part of the housing 30 is supported by the outer wall 103 of the flexible piece 10, the outer wall 103 abuts against the outer shell, and the outer wall 103 abuts against the circuit board to limit displacement of the circuit board. The housing 30 encapsulates the flexible piece 10 and the component 20 to form a microphone. The microphone structure is simple and easy to produce. Compared with a capacitive airflow sensor 201, the microphone is simpler, more reliable, and lower in cost in terms of component materials and manufacturing methods, and is suitable for mass production.

[0057] The atomizer 1000 microphone device 100 includes a dustproof screen arranged on the shell 30.

[0058] Please refer to Figure 12a , Figure 12a is a schematic diagram of the atomizer 1000 microphone in a static state, when the user does not release gas to the atomizer 1000, the second arc surface 1012 is close to the sensor 201, and the arc surface 101 is semicircular.

[0059] Please refer to Figure 12b , Figure 12b is a schematic diagram of the atomizer 1000 microphone in an inhaling state, when the user releases gas to the atomizer 1000, the gas is inhaled from the inhaling surface, the gas drives the second arc surface 1012 to deform away from the sensor 201, the magnetic beads are driven away from the bottom sensor 201 by the deformation of the second arc surface 1012, and when the distance away from the sensor 201 exceeds the detection range of the sensor 201, the atomizer 1000 controls the atomization assembly to atomize the tobacco tar in the oil tank to generate smoke.
