Description

Technical Field

[0001] The utility model relates to the technical field of atomization equipment, in particular to atomization equipment. Background Art

[0002] As a consumer electronic product, there are more and more types of atomizer devices, and their applications are becoming more and more extensive. Capacitive microphones are the mainstream components used by most atomizer devices to control the start and stop of atomizer devices. The principle is that when a user uses an atomizer device, the atomizer gas path of the atomizer device will generate negative pressure due to the airflow passing through, causing the conductive film of the microphone to deform, thereby causing the microphone to produce a capacitance change. When the capacitance change reaches a certain threshold, the circuit board controls the battery to power the atomizer core, causing the aerosol matrix adsorbed in the atomizer device to be atomized.

[0003] However, there are at least the following shortcomings when only relying on the microphone to start the atomization device:

[0004] First, the pneumatic induction switch of the microphone is easily affected by the environment. For example, factors such as humidity and temperature may affect the measurement accuracy of capacitance. When the liquid in the atomization gas path or the liquid generated by the circuit board during the production process flows into the microphone, or the liquid solidifies and blocks the atomization airway, the microphone may not be able to sense the pressure change of the atomization gas path, and thus no capacitance change will occur, affecting the startup control of the atomization equipment.

[0005] Secondly, a capacitive microphone can be regarded as a capacitive sensor. Limited by the geometric dimensions of the electrode plate, the capacitance of the capacitive sensor is very small, generally tens to hundreds of picofarads, and has poor load capacity. At the same time, the parasitic capacitance such as the connecting lead cable capacitance, the stray capacitance of the electronic circuit, and the capacitance formed by the capacitor plate and the surrounding conductor is relatively large. Since the parasitic capacitance changes randomly, the microphone is in an unstable working state, which reduces its sensitivity and affects its sensing accuracy. In severe cases, it may even fail to work.

[0006] Third, the microphone may be triggered by mistake, causing the atomization device to be turned on when not in use, posing safety hazards such as spontaneous combustion.

[0007] In summary, the use of capacitive microphones has problems such as unstable triggering and insufficient accuracy, which affects the user experience of the atomization device. Utility Model Content

The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0035] Figure 1 This is a schematic diagram of the structure of an atomization device provided by an embodiment of the present application. Figure 1As shown, the atomization device provided in the embodiment of the present application includes a housing 100 , a first sensor 110 and a control module 120 , wherein the first sensor 110 is encapsulated on the outer surface or the inner surface of the housing 100 .

[0036] In this embodiment, the first sensor 110 includes a sensitive element, and the sensitive element is electrically connected to the control module 120 .

[0037] In some embodiments, the sensitive element has a first electrode and a second electrode, the first electrode is connected to the housing 100, and the second electrode is electrically connected to the control module 120. A conductive element is disposed in the housing 100, the first electrode of the sensitive element is connected to the housing 100 through the conductive element, a control circuit or a control chip is disposed in the control module 120, and the second electrode of the sensitive element is electrically connected to a pin of the control circuit or the control chip.

[0038] When the sensitive element in the first sensor 110 senses a pressure change at a corresponding position of the shell 100 where the first sensor 110 is encapsulated, the sensitive element generates an electrical signal corresponding to the pressure change based on the amount of pressure change, and transmits the electrical signal to the control module 120 through its second electrode. The control module 120 responds to the electrical signal to generate a control signal for controlling the atomization device to be turned on or off, so as to realize the start and stop control of the atomization device.

[0039] In some embodiments, the first sensor 110 is disposed at the mouthpiece of the atomizing device housing 100 .

[0040] It is understandable that the first sensor 110 can be set at any position on the outer surface or inner surface of the housing 100. When the user is ready to use the atomizer device, the user takes out the atomizer device and prepares to smoke, the position of the first sensor 110 can sense the external pressure from the user, so that it generates an electrical signal and transmits it to the control module 120. However, in practice, if the first sensor 110 is located at the fuselage corresponding to the position of the housing 100, it may be untouched, which reduces the accuracy of the atomizer device to judge whether to start or stop. Based on the fact that the user needs to suck on the cigarette holder when the atomizer device is used, the pressure change at the cigarette holder can determine that the user is determined to use the atomizer device. Therefore, the first sensor 110 is set at the cigarette holder of the housing 100 of the atomizer device. When the stress at the cigarette holder changes, the sensitive element of the first sensor 110 will also be deformed together. At this time, the resistance value of the first sensor 110 changes, and then an electrical signal is generated according to the change of the voltage on the resistor, which is transmitted to the control module 120 to realize the start and stop control of the atomizer device. Exemplarily, when the force at the cigarette holder increases, the deformation of the sensitive element of the first sensor 110 increases, and the electrical signal at this time indicates that the atomization device is turned on, and the control module 120 sends a control signal to control the atomization device to be turned on; correspondingly, when the force at the cigarette holder decreases, the deformation of the sensitive element of the first sensor 110 decreases, and the electrical signal at this time indicates that the atomization device is turned off, and the control module 120 sends a control signal to control the atomization device to be turned off.

[0041] In some embodiments, the first sensor 110 can be tightly bonded to the mouthpiece of the electronic cigarette by a special adhesive.

[0042] In some embodiments, the first sensor 110 is a resistive sensor, which may be a resistive strain sensor or a piezoresistive sensor.

[0043] In the atomization device provided in the embodiment of the present application, a resistive first sensor 110 is used to replace the common microphone switch in the prior art to realize the control of opening or closing the atomization device, which can effectively prevent the atomization device from being unable to start or automatically starting due to environmental conditions, liquid in the atomization gas path or liquid generated by the circuit board during the production process flowing into the microphone air hole, and liquid solidification blocking the atomization gas path. At the same time, the resistive sensor will not be affected by the components or lines on the peripheral circuit to generate parasitic capacitance, thereby affecting its sensing accuracy.

[0044] The materials and structures used in resistive sensors have good durability and stability, and can maintain a long service life even in harsh working environments. The design and manufacturing are very flexible and can be customized and optimized according to different application requirements, making it possible to achieve miniaturization, integration and variety to meet various specific measurement requirements, making it very suitable for use in atomization equipment.

[0045] For example, the structure of the resistance strain sensor is relatively simple, generally composed of elastic sensitive elements, resistance strain gauges, compensation resistors and housings. This simple structure makes the sensor easy to manufacture and maintain. For the resistance strain sensor, it has many significant advantages, specifically: the resistance strain sensor can accurately measure various physical quantities, such as force, pressure, torque, displacement, acceleration and temperature, etc., can adapt to different measurement needs, and can accurately measure from small changes to large changes, providing high measurement accuracy. It has good frequency response characteristics and can quickly respond to various dynamic measurement needs. In the long-term use process, its performance is stable and reliable, and is not easily affected by the external environment.

[0046] In some embodiments, the sensitive element of the resistance strain sensor is a resistance strain gauge, which may be a metal resistance strain gauge or a semiconductor resistance strain gauge.

[0047] Among them, metal resistance strain gauges are generally made of metal foil or wire materials, common ones are steel, copper-nickel, chromium-nickel, platinum-iridium, etc. Metal resistance strain gauges have the advantages of high sensitivity, good stability, and fast response speed. They are widely used in strength testing, displacement measurement and other fields.

[0048] Semiconductor resistance strain gauges use the strain effect of semiconductor materials to make sensors. Common ones include silicon, germanium, silicon nitride, silicon carbide, etc. Since semiconductor materials have the characteristics of high nonlinear coefficient and strong temperature compensation ability, semiconductor resistance strain gauges are widely used in pressure measurement, weighing, flow meter and other fields.

[0049] For another example, piezoresistive sensors also have the same advantages as resistive sensors, such as high sensitivity, high precision, fast response, dynamic performance and stability. Piezoresistive sensors usually have lower power consumption, which helps to reduce the energy consumption of equipment and extend battery life. The electrical signals output by piezoresistive sensors are easy to digitally process and analyze, which facilitates automatic control and remote monitoring. They are usually manufactured using integrated processes, so they are small in size and light in weight, which makes them easy to install and integrate into various devices, especially suitable for occasions with limited space, such as atomization equipment.

[0050] Figure 2 This is a schematic diagram of the structure of an atomization device provided in another embodiment of the present application. Figure 2 As shown, the atomization device provided in the embodiment of the present application further includes a heating component 130 on the basis of any of the above embodiments, and the heating component 130 is electrically connected to the control module 120.

[0051] In this embodiment, the control module 120 can generate a control signal for controlling the opening or closing of the atomization device in response to the electrical signal output by the first sensor 110 to control the opening or closing of the atomization device. At the same time, when the control module 120 receives the electrical signal output by the first sensor 110, it also generates a heating control signal and transmits it to the heating component 130 to control the heating component 130 to start or stop heating according to a preset heating temperature curve.

[0052] The control module 120 can also directly generate a control signal for controlling the heating component 130 to start or stop heating in response to the electrical signal output by the first sensor 110, and control the atomization device to be turned on or off by controlling whether the heating component 130 is heated.

[0053] Figure 3 This is a circuit connection diagram of an atomization device provided in one embodiment of the present application. Figure 3 As shown, the control module 120 in the atomization device includes a small control chip U1, a power pin of the control chip U1 is connected to an external input power supply, and power filtering is performed through a capacitor C1, an output pin of the control chip U1 is connected to a heating wire R1 in a heating component 130, and a switch pin of the control chip U1 is connected to one end of a first sensor P1.

[0054] When the first sensor P1 senses pressure, the resistance value of the first sensor P1 changes, causing the voltage across the resistor to change, and an electrical signal is generated according to the voltage change, which is transmitted to the control chip U1; at this time, the control chip U1 generates a heating control signal according to the received electrical signal, and transmits it to the heating wire R1, controlling the heating wire R1 to start heating.

[0055] Figure 4 This is a schematic diagram of the structure of an atomization device provided in another embodiment of the present application. Figure 4 As shown, the atomization device provided in the embodiment of the present application further includes a second sensor 140 on the basis of any of the above embodiments.

[0056] An atomizing airway is provided in the shell 100 of the atomizing device, and a second sensor is provided at the air inlet end of the atomizing airway. When the second sensor senses the air pressure change caused by the control flow in the atomizing airway due to the user's suction action, an electrical signal is generated according to the sensed change and transmitted to the control module 120 as a second control signal, which is used to generate a control signal for controlling the atomizing device to be turned on or off, so as to avoid the atomizing device from being accidentally started when the first sensor 110 fails, or to provide a backup option.

[0057] In some embodiments, the second sensor may also be a resistive film flow sensor. The resistive film flow sensor is disposed in the atomizing airway, and the film flow sensor has a sensing film, which may present different resistance values ​​when subjected to airflows of different intensities, and transmits electrical signals representing different resistance values ​​to the control module 120, and controls the opening or closing of the atomizing device through the control module 120, so that different atomizing effects may be produced for different airflow intensities, thereby improving the user experience of the atomizing device.

[0058] In some embodiments, the second sensor may be a microphone used in a conventional atomization device. When airflow passes through, the microphone responds and triggers the control module 120, controls the atomizer to start working, and the aerosol matrix in the atomization device is atomized after being heated; when the inhalation stops, the airflow in the microphone sensor disappears, the microphone switch is turned off, the control module 120 of the control circuit stops working, and the atomizer stops working.

[0059] It should be noted that, based on certain limitations of the aforementioned microphone sensor in the atomization device, it is still retained in the atomization device of this embodiment as a backup option. When the first sensor 110 fails, it can still be used as a component to control the start and stop of the atomization device.

[0060] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the inspiration of the present application, ordinary technicians in the field can make some simple deductions, deformations or substitutions based on the idea of ​​the present application without departing from the scope of protection of the purpose of the present application and the claims. All of these are within the protection of the present application.
