Background
It is well known that cigarettes, whether they are active or passive, can cause serious harm to the health of smokers, mainly because of the tar contained in the cigarettes. Tar contains thousands of components, of which tens belong to carcinogens. Cigarette manufacturers try to use various methods to remove tar or carcinogens from tar, but the results are not satisfactory. Later, an emulated electronic cigarette product was proposed. It not only has the same appearance as a cigarette, but also can produce the same smoke, taste and feeling of a cigarette. Electronic cigarettes typically include an inductive controller, a memory in which the tobacco liquid is stored, and an aerosol generator for atomizing the tobacco liquid. The induction controller can respond to the inhalation action of the smoker to control the atomization generator to work to atomize the tobacco liquid in the storage into fog. The birth of the electronic cigarette meets the requirement that a plurality of smokers avoid inhaling tar in the process of smoking the cigarette. Smokers can select the nicotine-only tobacco liquid and use the electronic cigarette to smoke, the pleasure of smoking real cigarettes can be generated, and the electronic cigarette is gradually a smoking cessation tool and is popularized and applied. Furthermore, tobacco juice with medicinal value can be selected for smoking to treat respiratory diseases, and the electronic cigarette can also be used as a medical tool.
Currently, chinese patent 201080003430.9 discloses an electronic cigarette, which comprises an
Disclosure of Invention
In the electronic cigarette disclosed in chinese patent 201080003430.9, the conductive back plate is electrically connected to the printed circuit board through a conductive ring. The user may shift the electronic cigarette at any angle during the use of the electronic cigarette, and if there is no stable radial positioning structure between the conductive back plate and the conductive ring, the electronic cigarette is very easy to loose, bias and complete the separation, which finally results in poor electrical contact and the function of the electronic cigarette is not effective, and no effective solution is proposed in patent 201080003430.9.
In order to solve the technical problems, the invention provides an internal-stability type integrated sensor and controller, which comprises a cylindrical metal shell, wherein a control circuit board, a capacitor plate positioned below the control circuit board and a capacitor movable diaphragm positioned below the capacitor plate and arranged in parallel are sequentially arranged in the shell from top to bottom; the capacitor is characterized in that an annular conducting ring is arranged between the control circuit board and the capacitor polar plate, the capacitor polar plate and the conducting ring are correspondingly arranged up and down, so that the conducting ring and the outer shell are provided with the insulation space, the conducting ring not only enables an electric signal port of the control circuit board to be electrically connected with the capacitor polar plate, but also enables the control circuit board and the capacitor polar plate to be provided with an up-down interval in the up-down direction; the outer shell is internally provided with an annular insulating ring, and the insulating ring is positioned in the insulating space between the capacitor plate, the conducting ring and the outer shell.
According to the technical scheme, compared with the prior art, the invention has the beneficial technical effects that: firstly, because the insulating ring is located in the insulating space between the capacitor plate, the conducting ring and the outer shell, the insulating ring can not only keep the insulating space between the capacitor plate, the conducting ring and the outer shell constantly, and avoid direct contact between the capacitor plate, the conducting ring and the outer shell, but also limit the capacitor plate and the conducting ring in the inner ring space thereof to limit the space in which the capacitor plate and the conducting ring can move radially relative to each other, and avoid that the capacitor plate and the conducting ring are deviated in the radial direction to be separated from each other and further influence the electric connection stability between the capacitor plate and the conducting ring. In addition, the conducting ring is electrically connected with one electric signal port of the control circuit board and the capacitor plate, and an up-down interval is formed between the control circuit board and the capacitor plate in the up-down direction, so that the conducting ring is utilized to simplify the electric connection structure and installation operation between the electric signal port of the control circuit board and the capacitor plate, the interval can be used as the heat dissipation distance of the control circuit board and the capacitor plate, and the heat dissipation efficiency is favorably improved.
The further technical scheme can also be that the top of the insulating ring is not contacted with the control circuit board. According to the technical scheme, the distance is configured between the top of the insulating ring and the control circuit board in the vertical direction, so that even if the height of the insulating ring has a manufacturing error, the insulating ring cannot be pressed on the control circuit board to influence the electric connection between the control circuit board and the conducting ring.
The capacitive moving diaphragm needs to have the capacity of instantaneously deforming correspondingly with the change of the air pressure and also needs to have the capacity of automatically recovering to the original shape when the air pressure returns to the normal pressure state. In view of this, a further technical solution can be adopted, in which the lower opening portion of the outer casing has an annular lower skirt extending inward, the capacitive movable diaphragm is in a disk shape and includes an annular metal base ring and a thin film sheet arranged on an upper end face of the base ring, a metal film layer is arranged on the thin film sheet, the metal film layer is located on an inner side face of the thin film sheet facing one side of the base ring and electrically connected to the base ring, and a lower end face of the base ring faces the lower skirt and electrically connected to the lower skirt.
The metal base ring becomes a framework of the capacitance movable diaphragm, and can support, fix and tighten the diaphragm and the metal film layer arranged on the diaphragm. And the metal film layer can be conveniently installed on the integrated sensing and control device by utilizing the metal base ring, so that the damage to the metal film layer caused by direct contact during the installation process is reduced. Secondly, the space inside the ring of the metal base ring can also be an avoidance space during deformation and extension of the metal film layer. In addition, the metal base ring can conduct the electric signal of the metal film layer.
The thin film sheet becomes a carrier for bearing the metal film layer, and the metal film layer can optimize the deformation performance and the recovery performance of the metal film layer by utilizing the physical characteristics of the thin film sheet through a layout structure arranged on the thin film sheet.
The metal film layer is positioned on the inner side surface of the thin film sheet facing to one side of the base ring, so that short circuit among the base ring, the metal film layer and the capacitor plate is prevented by utilizing the insulation characteristic of the thin film sheet, and the capacitor characteristic can be ensured to be kept among the metal film layer and the capacitor plate.
The lower end face of the base ring faces the lower skirt edge, and the above features define the layout direction of the lower end face of the base ring and indirectly define the installation direction of the thin film piece. Accordingly, the thin film sheet and the metal film layer do not directly contact the lower skirt but contact the lower skirt through the base ring.
According to the technical scheme, the capacitive movable diaphragm comprises the metal base ring, the thin film sheet and the metal film layer arranged on the thin film sheet, the capacitive movable diaphragm has proper structural strength through the metal base ring, the metal film layer is arranged on the thin film sheet, so that the metal film layer can have chargeable characteristics by utilizing the metal characteristics of the metal film layer, and the deformation performance and the recovery performance of the metal film layer are optimized by utilizing the physical characteristics of the thin film sheet. The capacitor moving diaphragm has the characteristic of soft and hard, and the installation convenience is also met on the basis of meeting the elasticity requirement.
The technical scheme can be further that the upper opening part of the outer shell is provided with an annular upper skirt edge extending inwards, another electric signal port of the control circuit board is electrically connected with the upper skirt edge so that the capacitor pole plate and the capacitor movable diaphragm are respectively connected with the control circuit in the control circuit board through electric signals as two poles of a capacitor unit, the control circuit board is positioned below the upper skirt edge, and the upper skirt edge and the lower skirt edge are matched and tightly pressed in the upper direction and the lower direction in the outer shell and are sequentially arranged on the control circuit board, the conducting ring, the capacitor pole plate and the capacitor movable diaphragm. According to the technical scheme, the movable gaps of the control circuit board, the conducting ring, the capacitor plate and the capacitor movable diaphragm in the axial direction are reduced through the pressing effect of the upper skirt edge and the lower skirt edge, so that the axial shaking of the control circuit board, the conducting ring, the capacitor plate and the capacitor movable diaphragm is reduced, the positioning stability of the control circuit board, the conducting ring, the capacitor plate and the capacitor movable diaphragm in the axial direction is improved, the control circuit board and the upper skirt edge are favorably strengthened, the conducting ring is respectively connected with the control circuit board, the capacitor plate and the capacitor movable diaphragm with the electric connection stability between the lower skirt edges, and the assembly structure and the assembly operation of the integrated sensor and controller are simplified.
The further technical scheme can also be that a control IC is arranged on the control circuit board, and the control IC is positioned below the control circuit board and extends into the upper and lower spacing intervals defined by the conductive ring. This is advantageous for protecting the control IC from damage due to collision with foreign objects, and also for reducing the overall volume of the integrated sensor and controller.
The further technical scheme can also be that the control circuit board and the capacitor plate are respectively provided with a plate through hole. Thus, the polar distance space between the capacitor polar plate and the capacitor moving diaphragm is communicated with the external space outside the outer shell through the plate through hole, the plate through hole is used for transmitting the changed air pressure caused by the air suction action to the capacitor moving diaphragm, and the capacitor moving diaphragm deforms in response to the air pressure change at the upper side and the lower side of the capacitor moving diaphragm.
If the dirt enters into the polar distance space between the capacitor plate and the capacitor movable diaphragm and reduces the insulativity of an intermediate medium between the capacitor plate and the capacitor movable diaphragm, the function failure of the integrated sensing and controller can be caused very possibly.
In order to achieve that the sealing layer does not interfere with the electrical connection between the base ring and the outer housing, various solutions may be adopted, for example, the sealing layer may be made of a conductive material, so that the sealing layer not only enhances the sealing property between the base ring and the lower skirt, but also conducts an electrical signal between the base ring and the lower skirt by utilizing its own conductivity, so as to form an axial contact type (i.e., up and down direction) electrical signal connection structure between the base ring and the outer housing. Compared with the radial contact type electric signal connection structure formed by radially contacting the base ring with the outer shell, the radial contact type electric signal connection structure can reduce the bad phenomena of unstable and even failure of electric signal connection caused by bad contact due to manufacturing errors and assembly errors. According to the technical scheme, the integrated sensing and control device does not enable sensing airflow to pass through the outer shell but flows around the outside of the outer shell, and the air pressure variation caused by airflow flowing is utilized instead of flow and power of fluid impacting the capacitive movable diaphragm, namely the capacitive movable diaphragm or the electrode plate cannot be a windward device in the airflow, so that the pollution probability is greatly reduced; secondly, because the annular lower skirt edge and the side edge (also called as the lower edge) of the outer shell where the capacitive movable diaphragm is located are always windward, a sealing layer is arranged between the capacitive movable diaphragm and the lower skirt edge and used for preventing dirt from permeating into a polar distance space between the capacitive movable diaphragm and the capacitive polar plate, so that even if dirt possibly enters the outer shell from the lower edge of the outer shell, the sealing layer can also prevent the dirt from permeating into the polar distance space, the capacitive movable diaphragm and the capacitive polar plate can be maintained in a capacitance characteristic, and the service life of the integrated sensor and controller can be effectively prolonged.
The sealing layer can be an annular sealing rubber ring or an adhesive layer.
The technical scheme is that the novel garbage can comprises a garbage can body and a garbage can body, wherein the garbage can body is provided with a lower skirt edge and a lower opening part; the dirt blocking sheet is used for blocking external dirt from entering the outer shell from the lower opening part of the outer shell, and can transmit air pressure on two sides of the outer shell through the micropores of the dirt blocking sheet. According to the technical scheme, the dirt blocking sheet can be used for blocking external dirt outside the outer shell, so that the pollution to internal components of the outer shell, particularly the capacitance movable diaphragm and the capacitance polar plate is reduced, and the sensitivity and the service life of the integrated sensor and controller are favorably maintained.
In addition, the invention also provides an electronic cigarette applying the integrated sensing and controller, which is characterized by comprising a cigarette rod shell, wherein the integrated sensing and controller, a control unit and an atomization unit are arranged in the cigarette rod shell; the atomization unit is used for carrying out atomization treatment on an atomization object, and the atomization object comprises liquid or a carrier containing the liquid; the integrated sensing and controller is used for responding to an inhalation action, generating inhalation electric signals with different heights corresponding to the air pressure change caused by the inhalation action and providing the inhalation electric signals with different heights to the control unit, and the control unit is used for correspondingly controlling the atomization amount or the atomization power of the atomization unit according to the heights of the inhalation electric signals.
The technical solution may further be that the upper and lower spaces of the capacitive moving diaphragm are configured to generate different air pressure changes in response to different inhalation actions, and the capacitive moving diaphragm is configured to deform correspondingly in response to the different air pressure changes, so that corresponding different capacitance variations occur between the capacitive plate and the capacitive moving diaphragm; and the control circuit in the control circuit board is used for picking up the capacitance variation with different sizes to generate corresponding electric signals with different heights and providing the electric signals with different heights to the control unit.
According to the technical scheme, when airflow flows outside the outer shell, for example, the airflow flows from top to bottom outside the lower opening portion of the outer shell, the air pressure in the space below the capacitive moving diaphragm is reduced, and at the moment, the air pressures on the upper side and the lower side of the capacitive moving diaphragm are out of balance to drive the capacitive moving diaphragm to extend and deform downwards, so that the distance between the capacitive moving diaphragm and the capacitive pole plate is increased. On the contrary, when the air current flows from bottom to top outside the lower opening of the outer shell, the air pressure in the lower space is increased, and at the moment, the capacitor moving diaphragm extends upwards to deform, so that the distance between the capacitor moving diaphragm and the capacitor polar plate is reduced.
The further technical scheme can also be that the air conditioner further comprises a filtering circuit, wherein the filtering circuit is used for filtering noise signals caused by non-air suction actions and only providing the air suction electric signals with different heights to the control unit.
Further, the different levels of the inspiration electric signal can be a voltage signal, a current signal or a frequency signal.
The invention has the characteristics and advantages, so the invention can be applied to internal stable integrated sensing and control devices and electronic cigarette products.
