Specifically, at least one of the first end surface 2311 and the second end surface 2312 may be integrally disposed on the housing 231 to better protect the internal structure of the air flow sensor; or, the first end surface 2311 and the second end surface At least one of the end faces of the 2312 may also be detachably disposed on the housing 231 to facilitate replacement, disassembly, and the like of the housing 231 by the user.
电极232设置在壳体231的内部，沿壳体231的中心轴线方向设置，其表面可以设置为金属电极层，也可以设置为非金属电极层。其中，电极232的内部既可以为实心结构，也可以为空心结构。优选地，电极232的内部为空心结构，以便于在电极232和第一高分子薄膜233之间形成气流通道的同时，和/或电极232内部形成气流通道，同时，空心结构的电极232重量更小，从而使气流传感器的整体更加轻便；更优选地，在电极232上进一步设置有内外相通的通孔，以便增加气流通道内的气流大小，提升摩擦效果。第一高分子薄膜233为套设在电极232外部的筒状薄膜，且第一高分子薄膜233的形状和电极232的形状相匹配。第一高分子薄膜233上进一步开设有至少一个振膜，当气流经过上述进气孔时，气流通过上述气流通道带动振膜振动。其中，每个振膜具有与第一高分子薄膜233连接一体的固定端以及能够在气流的带动下与电极232相互摩擦的自由端。其中，每个振膜的固定端设置在靠近进气孔的一侧，每个振膜的自由端设置在靠近出气孔的一侧，这种设置方式用于保证当气流从进气孔吹入时，气流从每个振膜的固定端的方向吹入，从而可以实现较好的摩擦效果(发明人在实验中发现，当气流从振膜固定端的方向吹入时，振膜自由端的起振效果以及摩擦效果都较佳)。并且，电极232作为气流传感器的信号输出端。The electrode 232 is disposed inside the casing 231 and disposed along the central axis of the casing 231. The surface thereof may be provided as a metal electrode layer or as a non-metal electrode layer. The inside of the electrode 232 may be a solid structure or a hollow structure. Preferably, the inside of the electrode 232 is a hollow structure so as to form an air flow passage between the electrode 232 and the first polymer film 233, and/or an air flow passage is formed inside the electrode 232, and at the same time, the electrode 232 of the hollow structure is more weighty. Small, so that the whole of the airflow sensor is more light; more preferably, the electrode 232 is further provided with a through hole communicating with the inside and the outside to increase the airflow in the airflow passage and improve the friction effect. The first polymer film 233 is a tubular film that is sleeved outside the electrode 232, and the shape of the first polymer film 233 matches the shape of the electrode 232. The first polymer film 233 is further provided with at least one diaphragm. When the airflow passes through the air inlet hole, the airflow drives the diaphragm to vibrate through the airflow channel. Each of the diaphragms has a fixed end integrally connected to the first polymer film 233 and a free end that can rub against the electrode 232 under the action of the air flow. Wherein, the fixed end of each diaphragm is disposed on a side close to the air inlet hole, and the free end of each diaphragm is disposed on a side close to the air outlet hole, and the arrangement is used to ensure that when the airflow is blown from the air inlet hole At this time, the airflow is blown in from the direction of the fixed end of each diaphragm, so that a good friction effect can be achieved (the inventors found in the experiment that when the airflow is blown from the direction of the fixed end of the diaphragm, the vibration-starting effect of the free end of the diaphragm And the friction effect is better). Also, the electrode 232 serves as a signal output terminal of the air flow sensor.
具体地，第一高分子薄膜233与电极232之间间隔有预设距离，该预设 距离用于在电极232和第一高分子薄膜233之间形成气流通道，同时，该间距也用于为第一高分子薄膜233上的振膜提供足够的振动空间。具体实施中，上述预设距离控制在0.01-2.0mm之间。在未有气流流入情况下，第一高分子薄膜233上的振膜与电极232的表面未产生摩擦，未有感应电荷产生；当气流从第一端面2311上的进气孔流入时，气流产生的涡流使上述振膜的自由端产生振动，振动的自由端与电极232的表面产生相应频率的接触分离，即振膜与电极232的表面产生摩擦，进而在电极232上产生感应电荷。其中，电极232作为气流传感器的信号输出端，电极232上设置有与该电极相连的导线，则电极232表面的感应电荷被作为感应电信号通过上述导线输出。其中，电极232可以与外电路中的接地点共同形成电流回路，从而以单电极方式实现电信号输出。其中，上述电信号包括电压值、频率值等相关的电信号参数。经发明人测量发现，气流的气流流速越大，振膜的振动频率相应越高，则输出的电压值和频率值也越大。并且，发明人进一步从测量的数值中发现，气流流速与电压值V以及频率f之间为正比关系，即特定的电压值或者频率值对应一定的气流流速值，因此，通过获取输出的电压值以及频率值便可进一步通过计算来获取气流的流速以及流量。Specifically, the first polymer film 233 and the electrode 232 are separated by a preset distance, and the preset The distance is used to form a gas flow path between the electrode 232 and the first polymer film 233, and the space is also used to provide a sufficient vibration space for the diaphragm on the first polymer film 233. In a specific implementation, the preset distance is controlled to be between 0.01 and 2.0 mm. In the case where no airflow flows in, the diaphragm on the first polymer film 233 and the surface of the electrode 232 are not rubbed, and no induced charge is generated; when the airflow flows in from the air inlet hole on the first end face 2311, the airflow is generated. The eddy current causes the free end of the diaphragm to vibrate, and the free end of the vibration generates contact with the surface of the electrode 232 at a corresponding frequency, that is, the diaphragm and the surface of the electrode 232 are rubbed, thereby generating an induced charge on the electrode 232. Wherein, the electrode 232 is used as a signal output end of the air flow sensor, and the electrode 232 is provided with a wire connected to the electrode, and the induced charge on the surface of the electrode 232 is output as an induced electrical signal through the wire. Wherein, the electrode 232 can form a current loop together with the grounding point in the external circuit, thereby realizing the electrical signal output in a single electrode manner. Wherein, the electrical signal includes an electrical signal parameter related to a voltage value, a frequency value and the like. According to the measurement by the inventors, the larger the flow velocity of the airflow, the higher the vibration frequency of the diaphragm, and the larger the output voltage value and the frequency value. Moreover, the inventors further found from the measured values that the flow velocity is proportional to the voltage value V and the frequency f, that is, the specific voltage value or frequency value corresponds to a certain flow velocity value, and therefore, the output voltage value is obtained. And the frequency value can be further calculated to obtain the flow rate and flow rate of the airflow.

That is, there is a certain gap between the casing 241 and the first polymer film 243 and between the first polymer film 243 and the electrode 242.
接下来具体介绍电极242以及第一高分子薄膜243。首先介绍电极242。具体地，电极242沿壳体241的中心轴线方向设置，在形状上，电极242的形状可以为圆柱状、棱柱状、圆台状、以及棱台状等形状；其中，为了增加电极242的摩擦面积，优选电极242的形状为侧表面为平面的棱柱状或者棱台状。例如，如图2h所示，电极242为中空三棱柱形状。在结构上，电极242既可以为实心结构，也可以为空心结构。优选地，电极242的内部为空心结构，以便于在电极242和第一高分子薄膜243之间形成气流通道的同时，和/或电极242内部形成气流通道，同时，空心结构的电极242重量更小，从而使气流传感器的整体更加轻便；更优选地，在电极242上进一步设置有内外相通的通孔，以此来增加气流通道内的气流大小，从而进一步提升摩擦 效果。Next, the electrode 242 and the first polymer film 243 will be specifically described. First, the electrode 242 will be described. Specifically, the electrode 242 is disposed along the central axis direction of the housing 241. In shape, the shape of the electrode 242 may be a cylindrical shape, a prism shape, a truncated cone shape, and a prismatic shape; wherein, in order to increase the friction area of the electrode 242 Preferably, the shape of the electrode 242 is a prismatic shape or a prismatic shape in which the side surface is flat.

Preferably, the inside of the electrode 242 is a hollow structure so as to form an air flow passage between the electrode 242 and the first polymer film 243, and/or an air flow passage is formed inside the electrode 242, and at the same time, the electrode 242 of the hollow structure is more weighty. Small, so that the whole of the air flow sensor is more light; more preferably, the electrode 242 is further provided with a through hole communicating with the inner and outer portions, thereby increasing the airflow in the air flow passage, thereby further improving the friction. effect.

Specifically, in shape, corresponding to the electrode 242, the shape of the first polymer film 243 may be various shapes such as a hollow cylindrical shape, a hollow prism shape, a hollow truncated cone shape, and a hollow prism shape; When the contact area of the polymer film 243 and the electrode 242 is rubbed, it is preferable that the first polymer film 243 has a hollow prism shape or a hollow prism shape having a side surface, and the shapes of the first polymer film 243 and the electrode 242 are maintained. match. In other words, if the shape of the electrode 242 is cylindrical, the first polymer film 243 has a hollow cylindrical shape; and if the shape of the electrode 242 is a triangular prism, the first polymer film 243 corresponds to a hollow triangular prism. Wait. For example, as shown in FIG. 2h, the first polymer film is matched in shape to the electrode. In FIG. 2h, the electrode 242 has a triangular prism shape, and the shape of the first polymer film 243 is also a hollow triangular prism shape.
具体地，当壳体241以及电极242的形状为圆柱状或棱柱状，且第一高分子薄膜243的形状为中空圆柱状或中空棱柱状时，第一高分子薄膜243的内径大于电极242的外径，且壳体241的内径大于第一高分子薄膜243的外径，以便于在壳体241与第一高分子薄膜243之间、以及第一高分子薄膜243与电极242之间形成间隙。当壳体241以及电极242的形状为圆台状或棱台状，且第一高分子薄膜243的形状为中空圆台状或中空棱台状时，第一高分子薄膜243的上表面的内径大于电极242的上表面的外径，且壳体241的上表面的内径大于第一高分子薄膜243的上表面的外径；第一高分子薄膜243的下表面的内径大于电极242的下表面的外径，且壳体241的下表面的内径大于第一高分子薄膜243的下表面的外径，以便于在壳体241与第一高分子薄膜243之间、以及第一高分子薄膜243与电极242之间形成间隙。其中，第一高分子薄膜243为中空状，即，第一高分子薄膜243是两端贯穿的中空结构，在上文中，第一高分子薄膜243上下表面是指：由第一高分子薄膜243的两侧分别在壳体241的第一端面2411和第二端面2412上所限定的表面。同理，当电极242为空心时，电极242的上下表面也是类似含义。Specifically, when the shape of the housing 241 and the electrode 242 is cylindrical or prismatic, and the shape of the first polymer film 243 is a hollow cylindrical shape or a hollow prism shape, the inner diameter of the first polymer film 243 is larger than that of the electrode 242. The outer diameter of the housing 241 is larger than the outer diameter of the first polymer film 243 so as to form a gap between the housing 241 and the first polymer film 243 and between the first polymer film 243 and the electrode 242. . When the shape of the casing 241 and the electrode 242 is a truncated cone or a prismatic shape, and the shape of the first polymer film 243 is a hollow truncated cone shape or a hollow prismatic shape, the inner diameter of the upper surface of the first polymer film 243 is larger than the electrode. The outer diameter of the upper surface of the 242, and the inner diameter of the upper surface of the housing 241 is larger than the outer diameter of the upper surface of the first polymer film 243; the inner diameter of the lower surface of the first polymer film 243 is larger than the outer surface of the electrode 242 The inner diameter of the lower surface of the casing 241 is larger than the outer diameter of the lower surface of the first polymer film 243 so as to be between the casing 241 and the first polymer film 243, and the first polymer film 243 and the electrode. A gap is formed between 242. The first polymer film 243 is hollow, that is, the first polymer film 243 is a hollow structure that is penetrated at both ends. In the above, the upper and lower surfaces of the first polymer film 243 means: the first polymer film 243 The two sides are respectively defined on the first end surface 2411 and the second end surface 2412 of the housing 241. Similarly, when the electrode 242 is hollow, the upper and lower surfaces of the electrode 242 have similar meanings.
在结构上，当第一高分子薄膜243具有多个侧表面时，在第一高分子薄膜243的每个侧表面上进一步开设有至少一个振膜2431，如图2g所示，第一高分子薄膜的每个侧表面上都开设有两个振膜2431。当然，可以理解的 是，在具体实施中，第一高分子薄膜的每个侧表面上的振膜2431的数量并不限于两个，可以是一个，也可以为多个，其具体数量由本领域技术人员根据实际情况进行设置，本发明对此不作限制。其中，振膜2431具体用于：在气流通过进气孔之后，气流进入气流通道带动振膜2431振动。其中，上述气流通道的实现方式有多种，例如，既可以形成于电极242和第一高分子薄膜243之间，也可以形成于电极242内部，或者还可以同时在电极242和第一高分子薄膜243之间以及电极242内部形成气流通道。具体地，在第一种实现方式中，上述气流通道形成于电极242与第一高分子薄膜243之间的间隙内；在第二种实现方式中，除了在电极242与第一高分子薄膜243之间的间隙内形成气流通道之外，还可以进一步在电极242的内部也形成气流通道，例如在电极242的内部设置数个内外相通的通孔，或者将电极242的内部设置为空心结构等等，总之，在电极242内部设置气流通道能够更有利于气流的加速流动，从而实现更加理想的摩擦效果。本领域技术人员可以根据需要灵活设置上述的气流通道。Structurally, when the first polymer film 243 has a plurality of side surfaces, at least one diaphragm 2431 is further formed on each side surface of the first polymer film 243, as shown in FIG. 2g, the first polymer Two diaphragms 2431 are formed on each side surface of the film. Of course, understandable In a specific implementation, the number of the diaphragms 2431 on each side surface of the first polymer film is not limited to two, and may be one or plural, and the specific number thereof is determined by a person skilled in the art according to actual conditions. The setting is made, and the present invention does not limit this. The diaphragm 2431 is specifically configured to: after the airflow passes through the air inlet hole, the airflow enters the airflow channel to drive the diaphragm 2431 to vibrate. The air flow channel may be implemented in various manners, for example, may be formed between the electrode 242 and the first polymer film 243, or may be formed inside the electrode 242, or may be simultaneously at the electrode 242 and the first polymer. Airflow channels are formed between the membranes 243 and inside the electrodes 242. Specifically, in the first implementation manner, the air flow channel is formed in a gap between the electrode 242 and the first polymer film 243; in the second implementation, in addition to the electrode 242 and the first polymer film 243 In addition to the formation of the air flow path in the gap, a gas flow path may be further formed inside the electrode 242. For example, a plurality of inner and outer communication through holes may be provided inside the electrode 242, or the inside of the electrode 242 may be a hollow structure or the like. Etc. In summary, the provision of an air flow passage inside the electrode 242 can be more advantageous for the accelerated flow of the air flow, thereby achieving a more desirable friction effect. Those skilled in the art can flexibly set the above air flow passages as needed.
接下来介绍振膜2431的结构。振膜2431的结构具体如下：第一高分子薄膜243上的每个振膜2431具有与第一高分子薄膜2431连接一体的固定端以及能够在气流的带动下与电极相互摩擦的自由端。其中，振膜2431的固定端设置在靠近进气孔的一侧，振膜2431的自由端设置在靠近出气孔的一侧，这种设置方式用于保证当气流从进气孔吹入时，气流从每个振膜的固定端的方向吹入，从而可以实现较好的摩擦效果。其中，优选地，振膜2431可以是从第一高分子薄膜243上预先切割以形成预设形状的振膜，相应地，切割振膜2431后在第一高分子薄膜243上形成的空缺部分能够更好地进出气流，从而提升摩擦效果；而且，振膜2431的自由端能够在气流带动下往复运动，即：振膜2431在气流作用力的带动下在上述空缺部位产生相应频率的振动，该振动能够使振膜2431的自由端与电极242的表面产生摩擦，从而实现振膜2431在气流作用力的带动下产生摩擦的效果。并且，进一步地，本领域技术人员还可以根据实际中的实验情况将振膜2431的结构设计为能够充分利用惯性实现持续起振的结构，例如，设计振膜2431自由端的大小略大于振膜2431固定端的大小，则振膜2431的自由端在受到气流作用力产生振动后，振动中的振膜2431会在惯性作用下持续振动，该惯性作用 与气流作用同时作用于振膜2431，进一步增加了振膜2431的振动效果，从而能够进一步提升摩擦效果。当然，在本发明的其它实施例中，也可以将多个预设形状的振膜固定设置在第一高分子薄膜243上，在这里，本发明对振膜2431的具体设置方式不做限定，只要能够起到接触摩擦效果既可。其中，振膜2431的形状可以为矩形、三角形、多边形以及扇形等形状，并且，振膜2431的长度可以由本领域技术人员根据振膜的形状进行适应性设置，以避免由于振膜过长或者过短导致的振膜振动不稳定或者无法起振的情况。其中，当振膜2431的数量为多个时，上述多个振膜按照阵列化方式设置在第一高分子薄膜243上，并且，为了提升摩擦效果，当第一高分子薄膜243为中空棱柱状时，可以在中空棱柱状的第一高分子薄膜243的每个侧表面上分别设置一个或多个振膜。如图2g所示，第一高分子薄膜为中空三棱柱状，振膜2431为多个分别设置在该第一高分子薄膜的各个侧表面上的矩形振膜，矩形振膜中有一边与第一高分子薄膜相连，从而形成该矩形振膜的固定端；其余三边为分离状，从而形成该矩形振膜的自由端。并且，从图2g中可以看出，振膜的数量可以为多个，图2g中的振膜以阵列化的方式排布在第一高分子薄膜243上。Next, the structure of the diaphragm 2431 will be described. The structure of the diaphragm 2431 is specifically as follows: each diaphragm 2431 on the first polymer film 243 has a fixed end integrally connected to the first polymer film 2431 and a free end which can be rubbed against the electrode by the air flow. Wherein, the fixed end of the diaphragm 2431 is disposed on a side close to the air inlet hole, and the free end of the diaphragm 2431 is disposed on a side close to the air outlet hole, and the arrangement is used to ensure that when the airflow is blown from the air inlet hole, The air flow is blown in from the direction of the fixed end of each diaphragm, so that a good friction effect can be achieved. Preferably, the diaphragm 2431 is a diaphragm that is pre-cut from the first polymer film 243 to form a predetermined shape, and accordingly, the vacant portion formed on the first polymer film 243 after the diaphragm 2431 is cut can be The airflow is improved to improve the friction effect. Moreover, the free end of the diaphragm 2431 can reciprocate under the action of the airflow, that is, the diaphragm 2431 generates a corresponding frequency vibration in the vacant portion under the driving force of the airflow. The vibration can cause the free end of the diaphragm 2431 to rub against the surface of the electrode 242, thereby achieving the effect that the diaphragm 2431 generates friction under the action of the air force. Further, those skilled in the art can also design the structure of the diaphragm 2431 as a structure capable of fully utilizing inertia to achieve continuous vibration according to actual experimental conditions. For example, the design of the diaphragm 2431 has a free end slightly larger than the diaphragm 2431. The size of the fixed end, after the free end of the diaphragm 2431 is vibrated by the force of the airflow, the diaphragm 2431 in the vibration will continuously vibrate under the action of inertia, the inertia Simultaneously acting on the diaphragm 2431 at the same time as the air flow acts, the vibration effect of the diaphragm 2431 is further increased, so that the friction effect can be further improved. Of course, in other embodiments of the present invention, a plurality of diaphragms of a predetermined shape may be fixedly disposed on the first polymer film 243. Here, the specific arrangement of the diaphragm 2431 is not limited in the present invention. As long as it can achieve the contact friction effect. The shape of the diaphragm 2431 may be a rectangle, a triangle, a polygon, a fan, or the like, and the length of the diaphragm 2431 can be adaptively set by a person skilled in the art according to the shape of the diaphragm to avoid the diaphragm being too long or too long. A short diaphragm vibration is unstable or cannot be oscillated. Wherein, when the number of the diaphragms 2431 is plural, the plurality of diaphragms are disposed on the first polymer film 243 in an array manner, and the first polymer film 243 is hollow prismatic in order to enhance the friction effect. At this time, one or a plurality of diaphragms may be respectively disposed on each side surface of the first prismatic polymer film 243. As shown in FIG. 2g, the first polymer film is in the shape of a hollow triangular prism, and the diaphragm 2431 is a plurality of rectangular diaphragms respectively disposed on the respective side surfaces of the first polymer film, and the rectangular diaphragm has one side and the other A polymer film is connected to form a fixed end of the rectangular diaphragm; the remaining three sides are separated to form a free end of the rectangular diaphragm. Further, as can be seen from Fig. 2g, the number of the diaphragms may be plural, and the diaphragms in Fig. 2g are arranged in an array on the first polymer film 243.
具体地，为了便于摩擦，第一高分子薄膜243与电极242之间间隔预设距离，该预设距离用于为第一高分子薄膜243上的振膜提供足够的振动空间。具体实施中，该预设距离可以控制在0.01-2.0mm之间。具体地，上述预设距离可通过下述两种方式实现：在第一种实现方式中，将电极242的两端分别固定在壳体241的第一端面2411以及第二端面2412的内壁上，同时，将第一高分子薄膜243的两端也分别固定在壳体241的第一端面2411以及第二端面2412的内壁上，使固定之后的壳体241与第一高分子薄膜243之间保持分离，并使固定之后的电极242与第一高分子薄膜243之间存在上述预设距离，该种方式尤其适用于第一高分子薄膜243材质较硬的场景中。在第二种实现方式中，为了防止第一高分子薄膜243的中部与电极242相互接触从而无法有效分离，在电极242与第一高分子薄膜243之间进一步设置有：至少一个支撑结构244，支撑结构244用于在电极242和第一高分子薄膜243之间形成间隙，使第一高分子薄膜243上的振膜的自由端和电极242接触分离。具体实施中，在设置支撑结构244时，可以将支撑结构244一体化设置 在电极242和第一高分子薄膜243相对的侧表面上或者设置在第一高分子薄膜243和电极242相对的侧表面上，以防止支撑结构244由于脱落等原因导致第一高分子薄膜243的一面持续接触在电极242上，进而无法实现较为理想的摩擦效果；或者，也可以将支撑结构244设置为可拆卸的结构，以便于用户对支撑结构244进行拆卸和更换。其中，支撑结构244的厚度优选在0.01-2.0mm之间，则本领域技术人员还可以设置多组不同厚度的支撑结构244，以供用户可以根据实际中的不同情况选择不同厚度的支撑结构244进行拆卸更换。其中，支撑结构244的数量可以为一个，也可以为多个。当支撑结构244的数量为多个时，每相邻的两个支撑结构244之间互相间隔预设距离。其中，上述预设的距离能够保证各个振膜分别设置在每相邻的两个支撑结构244之间。即：在第一高分子薄膜243与支撑结构244未接触的部分设置对应的振膜，该振膜能够在气流带动的作用下产生振动，并且其振动过程不会受到支撑结构244的影响。总之，通过支撑结构244能够确保第一高分子薄膜243与电极242之间的有效分离，防止两个摩擦界面在接触后无法有效分离的情况发生，进而提升摩擦效果。上述的两种实现方式既可以单独使用也可以结合使用。Specifically, in order to facilitate friction, the first polymer film 243 and the electrode 242 are spaced apart by a predetermined distance, which is used to provide sufficient vibration space for the diaphragm on the first polymer film 243. In a specific implementation, the preset distance can be controlled between 0.01-2.0 mm. Specifically, the preset distance may be implemented in the following two manners: in the first implementation, the two ends of the electrode 242 are respectively fixed on the first end surface 2411 of the housing 241 and the inner wall of the second end surface 2412. At the same time, the two ends of the first polymer film 243 are also respectively fixed on the inner walls of the first end surface 2411 and the second end surface 2412 of the housing 241 to maintain the space between the fixed housing 241 and the first polymer film 243. The separation is performed, and the predetermined distance between the electrode 242 after the fixation and the first polymer film 243 is present. This method is particularly suitable for a scene in which the first polymer film 243 is hard. In the second implementation manner, in order to prevent the middle portion of the first polymer film 243 from contacting the electrode 242 and being unable to be effectively separated, at least one support structure 244 is further disposed between the electrode 242 and the first polymer film 243. The support structure 244 is for forming a gap between the electrode 242 and the first polymer film 243 such that the free end of the diaphragm on the first polymer film 243 is in contact with the electrode 242. In a specific implementation, when the support structure 244 is disposed, the support structure 244 can be integrated On the side surface of the electrode 242 opposite to the first polymer film 243 or on the side surface opposite to the first polymer film 243 and the electrode 242, the first polymer film 243 is prevented from being caused by the support structure 244 due to dropping or the like. The surface is continuously contacted on the electrode 242, so that the desired friction effect cannot be achieved. Alternatively, the support structure 244 can be configured as a detachable structure to facilitate the user to disassemble and replace the support structure 244. Wherein, the thickness of the support structure 244 is preferably between 0.01 and 2.0 mm, and those skilled in the art may also provide a plurality of sets of support structures 244 of different thicknesses, so that the user can select support structures 244 of different thickness according to different actual conditions. Disassemble and replace. The number of the support structures 244 may be one or plural. When the number of the support structures 244 is plural, each adjacent two support structures 244 are spaced apart from each other by a predetermined distance. Wherein, the preset distance can ensure that the respective diaphragms are respectively disposed between each adjacent two support structures 244. That is, a corresponding diaphragm is disposed in a portion of the first polymer film 243 that is not in contact with the support structure 244, and the diaphragm can generate vibration under the action of the airflow, and the vibration process is not affected by the support structure 244. In short, the support structure 244 can ensure effective separation between the first polymer film 243 and the electrode 242, preventing the two friction interfaces from being effectively separated after contact, thereby improving the friction effect. The above two implementations can be used alone or in combination.
介绍完气流传感器的结构之后，接下来，介绍上述气流传感器的工作原理：After introducing the structure of the airflow sensor, the following describes the working principle of the above airflow sensor:
在没有气流流入时，电极242与第一高分子薄膜243之间未产生摩擦，因此没有感应电荷产生；其中，电极242与第一高分子薄膜243通常采用极性相反的材质制作(例如电极一般通过易失电子的材质制作，而第一高分子薄膜则一般采用易得电子的材质制作)，此时，由于电极242与第一高分子薄膜243之间的预设距离较小，因此第一高分子薄膜243上的振膜会吸附在电极242的表面。当气流从壳体241第一端面上的进气孔流入时，气流产生的涡流使上述振膜的自由端产生振动，振动的自由端与电极242的表面产生相应频率的接触分离，即第一高分子薄膜243上的振膜与电极242的表面产生摩擦，则振膜与电极242上产生出相应的感应电荷。具体实施中，如图2h所示，第一高分子薄膜上的振膜与电极之间的摩擦示意图。其中，图2h中的电极242设置在第一高分子薄膜243的内部，与第一高分子薄膜243之 间存在一定的预设距离，当气流流入时，振膜2431在气流的带动下上下振动，与电极242之间产生快速的接触分离，即振膜2431与电极242的表面产生摩擦，生成感应电荷，感应电荷从电极242流出从而输出对应的电信号。其中，电极242与外电路中的接地点共同形成电流回路，从而以单电极方式实现电信号输出。When no airflow flows in, no friction occurs between the electrode 242 and the first polymer film 243, so no induced charge is generated; wherein the electrode 242 and the first polymer film 243 are usually made of a material having opposite polarity (for example, an electrode) It is made of a material that is easy to lose electrons, and the first polymer film is generally made of a material that is easy to obtain electrons. At this time, since the preset distance between the electrode 242 and the first polymer film 243 is small, the first The diaphragm on the polymer film 243 is adsorbed on the surface of the electrode 242. When the airflow flows in from the air inlet hole on the first end surface of the casing 241, the eddy current generated by the airflow causes the free end of the diaphragm to vibrate, and the free end of the vibration and the surface of the electrode 242 are in contact with each other at a corresponding frequency, that is, the first When the diaphragm on the polymer film 243 is rubbed against the surface of the electrode 242, a corresponding induced charge is generated on the diaphragm and the electrode 242. In a specific implementation, as shown in FIG. 2h, a friction diagram between the diaphragm and the electrode on the first polymer film is shown. The electrode 242 in FIG. 2h is disposed inside the first polymer film 243 and is adjacent to the first polymer film 243. There is a certain preset distance. When the airflow flows in, the diaphragm 2431 vibrates up and down under the action of the airflow, and a rapid contact separation occurs between the diaphragm 242 and the electrode 242, that is, the diaphragm 2431 rubs against the surface of the electrode 242 to generate an induced charge. The induced charge flows out of the electrode 242 to output a corresponding electrical signal. Wherein, the electrode 242 forms a current loop together with the grounding point in the external circuit, thereby realizing the electrical signal output in a single electrode manner.
另外，上述结构的气流传感器主要是依靠第一高分子薄膜与电极之间的接触摩擦进行发电，在具体实施时，本领域技术人员还可以对上述气流传感器的内部结构进行各种改动和变形：In addition, the airflow sensor of the above structure mainly relies on the contact friction between the first polymer film and the electrode to generate electricity. In the specific implementation, those skilled in the art can also make various modifications and deformations to the internal structure of the airflow sensor:
例如，其中的电极242又可以进一步通过下述的两种方案实现：For example, the electrode 242 therein can be further realized by the following two schemes:
方案一：电极242仅包括单一的金属电极层，相应地，第一高分子薄膜243上每个振膜的自由端能够在气流的带动下与电极242中的金属电极层相互摩擦。其中，因为金属与高分子聚合物摩擦，金属更易失去电子，因此将电极242的表面设置为金属电极层，采用金属电极与高分子聚合物(即第一高分子薄膜243)摩擦，能够有效增强感应电荷的产生并增加输出的电信号的灵敏度。在这里，电极242与第一高分子薄膜243的极性相反，电极242极易失电子，第一高分子薄膜243易得电子。即：上述金属电极层极易失电子，上述第一高分子薄膜极易得电子。Solution 1: The electrode 242 includes only a single metal electrode layer. Accordingly, the free end of each diaphragm on the first polymer film 243 can be rubbed against the metal electrode layer in the electrode 242 by the air flow. Wherein, since the metal is more likely to lose electrons due to friction with the polymer, the surface of the electrode 242 is set as a metal electrode layer, and the metal electrode and the high molecular polymer (ie, the first polymer film 243) are rubbed, which can effectively enhance Inductive charge generation and increased sensitivity of the output electrical signal. Here, the polarity of the electrode 242 is opposite to that of the first polymer film 243, the electrode 242 is extremely susceptible to electrons, and the first polymer film 243 is easily electron-accepting. That is, the metal electrode layer is extremely susceptible to electrons, and the first polymer film is extremely easy to obtain electrons.
方案二：不同于方案一中的单层结构，方案二中的电极为复合结构，具体地，电极242进一步包括：金属电极层以及设置在金属电极层外侧的第二高分子薄膜，则每个振膜的自由端能够在气流的带动下与电极242中的第二高分子薄膜相互摩擦。具体地，在本方案中，进一步在电极242的金属电极层之上设置一层第二高分子薄膜，例如，可以在电极242的金属电极层之上再涂刷一层第二高分子薄膜，则第一高分子薄膜243上的每个振膜的自由端在气流带动的作用下与电极242中的第二高分子薄膜之间相互摩擦产生感应电荷，即通过聚合物(第一高分子薄膜)与聚合物(第二高分子薄膜)之间的摩擦来产生感应电荷，并通过第二高分子薄膜内部的金属电极层输出电信号，从而实现了与上述方案一类似的摩擦效果。The second embodiment is different from the single layer structure in the first embodiment. The electrode in the second embodiment is a composite structure. Specifically, the electrode 242 further includes: a metal electrode layer and a second polymer film disposed outside the metal electrode layer. The free end of the diaphragm can be rubbed against the second polymer film in the electrode 242 by the air flow. Specifically, in the present solution, a second polymer film is further disposed on the metal electrode layer of the electrode 242. For example, a second polymer film may be further coated on the metal electrode layer of the electrode 242. Then, the free end of each diaphragm on the first polymer film 243 is rubbed by the air current and the second polymer film in the electrode 242 to generate an induced charge, that is, through the polymer (the first polymer film). The friction between the polymer and the polymer (second polymer film) generates an induced charge and outputs an electric signal through the metal electrode layer inside the second polymer film, thereby achieving a friction effect similar to that of the above-described first embodiment.
具体地，在方案一或方案二中，金属电极层的材质具体可以为金属或合金，其中金属可以是金、银、铂、钯、铝、镍、铜、钛、铬、锡、铁、锰、 钼、钨或钒；合金可以是铝合金、钛合金、镁合金、铍合金、铜合金、锌合金、锰合金、镍合金、铅合金、锡合金、镉合金、铋合金、铟合金、镓合金、钨合金、钼合金、铌合金或钽合金。除此之外，金属电极层的材质还可以进一步选自铟锡氧化物、石墨烯、银纳米线膜等非金属导电材料。第一高分子薄膜与第二高分子薄膜的材料选自聚酰亚胺薄膜、苯胺甲醛树脂薄膜、聚甲醛薄膜、乙基纤维素薄膜、聚酰胺薄膜、三聚氰胺甲醛薄膜、聚乙二醇丁二酸酯薄膜、纤维素薄膜、纤维素乙酸酯薄膜、聚己二酸乙二醇酯薄膜、聚邻苯二甲酸二烯丙酯薄膜、纤维(再生)海绵薄膜、聚氨酯弹性体薄膜、苯乙烯丙烯共聚物薄膜、苯乙烯丁二烯共聚物薄膜、人造纤维薄膜、聚甲基薄膜，甲基丙烯酸酯薄膜、聚乙烯醇薄膜、聚酯薄膜、聚异丁烯薄膜、聚氨酯柔性海绵薄膜、聚对苯二甲酸乙二醇酯薄膜、聚乙烯醇缩丁醛薄膜、甲醛苯酚薄膜、氯丁橡胶薄膜、丁二烯丙烯共聚物薄膜、天然橡胶薄膜、聚丙烯腈薄膜、丙烯腈氯乙烯薄膜和聚乙烯丙二酚碳酸盐薄膜中的一种。其中，原则上第一高分子薄膜和第二高分子薄膜的材质可以相同，也可以不同。但是，如果两层高分子薄膜的材质都相同，会导致摩擦起电的电荷量很小。因此优选地，第一高分子薄膜与第二高分子薄膜的材质不同。Specifically, in the first or second embodiment, the material of the metal electrode layer may specifically be a metal or an alloy, wherein the metal may be gold, silver, platinum, palladium, aluminum, nickel, copper, titanium, chromium, tin, iron, manganese. , Molybdenum, tungsten or vanadium; alloys may be aluminum alloys, titanium alloys, magnesium alloys, niobium alloys, copper alloys, zinc alloys, manganese alloys, nickel alloys, lead alloys, tin alloys, cadmium alloys, niobium alloys, indium alloys, gallium alloys , tungsten alloy, molybdenum alloy, niobium alloy or niobium alloy. In addition, the material of the metal electrode layer may be further selected from non-metallic conductive materials such as indium tin oxide, graphene, and silver nanowire film. The material of the first polymer film and the second polymer film is selected from the group consisting of polyimide film, aniline formaldehyde resin film, polyoxymethylene film, ethyl cellulose film, polyamide film, melamine formaldehyde film, polyethylene glycol butyl Acid ester film, cellulose film, cellulose acetate film, polyethylene adipate film, poly( diallyl phthalate film), fiber (recycled) sponge film, polyurethane elastomer film, styrene Propylene copolymer film, styrene butadiene copolymer film, rayon film, polymethyl film, methacrylate film, polyvinyl alcohol film, polyester film, polyisobutylene film, polyurethane flexible sponge film, polyparaphenylene Ethylene glycol dicarboxylate film, polyvinyl butyral film, formaldehyde phenol film, neoprene film, butadiene propylene copolymer film, natural rubber film, polyacrylonitrile film, acrylonitrile vinyl chloride film and polyethylene One of the propylene glycol carbonate films. In principle, the materials of the first polymer film and the second polymer film may be the same or different. However, if the two layers of polymer film are made of the same material, the amount of charge that causes triboelectric charging is small. Therefore, it is preferable that the material of the first polymer film and the second polymer film are different.
相应地，针对于上文提到的支撑结构244的设置，其相应方案如下：若电极242采用方案一中的结构，即：电极242的外层仅包括单一的金属电极层，则上文提到的支撑结构244对应设置在电极242金属电极层的外侧；若电极242采用方案二中的结构，即：电极242的外层的金属电极层上还进一步设置了第二高分子薄膜层，则上文提到的支撑结构244对应设置在电极242中的第二高分子薄膜层的外侧。Correspondingly, for the arrangement of the support structure 244 mentioned above, the corresponding scheme is as follows: If the electrode 242 adopts the structure in the first scheme, that is, the outer layer of the electrode 242 includes only a single metal electrode layer, The support structure 244 is correspondingly disposed on the outer side of the metal electrode layer of the electrode 242; if the electrode 242 adopts the structure in the second embodiment, that is, the second polymer film layer is further disposed on the metal electrode layer of the outer layer of the electrode 242, The support structure 244 mentioned above corresponds to the outer side of the second polymer film layer disposed in the electrode 242.
进一步地，在上述两个方案中，为了增加摩擦效果，还可以进一步对电极242的表面进行进一步设置，使电极242的表面形成平面状或者粗糙点状。其中，平面状电极为表面为光滑平面的电极，由于平面状电极摩擦产生的感应电荷的静电吸附力较小，即产生的静电吸附振膜的吸附力较小，因此在气流的作用下，当第一高分子薄膜243上的振膜与表面设置为平面状的电极242进行摩擦时，可以克服由于摩擦产生的静电力较大而带来的振膜振动不稳定的问题；粗糙点状电极为表面具有一定粗糙度的电极，由于其具有的较 大粗糙度表面在摩擦时会产生较多的感应电荷，因此当第一高分子薄膜243上的振膜与表面设置为粗糙点状的电极242进行摩擦时，粗糙点状电极的表面能够增加摩擦阻力，从而增加摩擦生成的感应电荷并增大输出电信号，提高电信号输出的灵敏度。其中，上述粗糙点状电极可以通过在电极242的表面进行打磨或者设置凹凸结构的方式实现，其中，上述凹凸结构可以是半圆形、条纹状、立方体型、四棱锥型、或圆柱形等规则形状或者其他不规则形状的凹凸结构。Further, in the above two aspects, in order to increase the friction effect, the surface of the electrode 242 may be further disposed such that the surface of the electrode 242 is formed into a planar shape or a rough spot shape. Wherein, the planar electrode is an electrode whose surface is a smooth plane, and the electrostatic adsorption force of the induced charge generated by the friction of the planar electrode is small, that is, the adsorption force of the generated electrostatic adsorption diaphragm is small, so under the action of the airflow, when When the diaphragm on the first polymer film 243 is rubbed against the electrode 242 whose surface is provided in a planar shape, the problem that the vibration of the diaphragm is unstable due to the large electrostatic force generated by the friction can be overcome; the rough spot electrode is An electrode with a certain roughness on the surface, due to its The large roughness surface generates a large amount of induced charges when rubbed, so that when the diaphragm on the first polymer film 243 is rubbed against the electrode 242 having a rough surface, the surface of the rough spot electrode can increase friction. Resistance, thereby increasing the induced charge generated by friction and increasing the output electrical signal, improving the sensitivity of the electrical signal output. Wherein, the rough dot electrode can be realized by grinding the surface of the electrode 242 or providing a concave-convex structure, wherein the concave-convex structure can be a semi-circular, stripe-shaped, cubic-shaped, quadrangular pyramid, or cylindrical rule. Concave structure of shape or other irregular shape.
另外，上述两种方案中的每一种方案，又可以进一步划分为两种实现方式：在第一种实现方式中，可以仅由电极242作为信号输出端；在第二种实现方式中，可以由电极242与另外的一个输出电极共同构成信号输出端，例如，可以将壳体241设置为金属壳体，从而使壳体241作为气流传感器的另一个信号输出端。也就是说，当壳体241为金属壳体时，可以设置壳体241作为另一个输出电极。具体地，壳体241构成气流传感器中的一个输出电极，在设置壳体241与第一高分子薄膜243之间的距离时，将上述两者的距离设置在预设距离的范围之内，例如可以将上述两者之间的距离设置在0.01-2.0mm之间，则当第一高分子薄膜243上的振膜在气流的带动下产生上下振动时，上述振膜不仅与电极242的电极表面产生摩擦，还可以进一步与壳体241的内表面产生摩擦，从而在壳体241的内表面上产生相应的感应电荷，则此时的壳体241可作为除电极242之外的另一个信号输出端。在这里，要说明的是，壳体241的材质可以设置为金属，也可以设置为除金属以外的其它具有导电性的材料；或者，壳体241还可以进一步设置为两层结构，即：可以将壳体241内部一层结构设置为金属，然后在上述金属之外再设置一层高分子薄膜材料等等。在这里，只要能够实现将壳体241作为另一个信号输出端，本发明对壳体241的材质以及结构不作限制。In addition, each of the foregoing two solutions may be further divided into two implementation manners: in the first implementation manner, only the electrode 242 may be used as the signal output end; in the second implementation manner, The signal output is formed by the electrode 242 and the other output electrode. For example, the housing 241 can be provided as a metal housing such that the housing 241 serves as another signal output of the air flow sensor. That is, when the housing 241 is a metal housing, the housing 241 may be provided as another output electrode. Specifically, the housing 241 constitutes one of the output electrodes of the air flow sensor. When the distance between the housing 241 and the first polymer film 243 is set, the distance between the two is set within a preset distance, for example. When the distance between the two is set to be between 0.01 and 2.0 mm, when the diaphragm on the first polymer film 243 is vibrated up and down by the air current, the diaphragm is not only the electrode surface of the electrode 242. The friction is generated, and further friction may be generated with the inner surface of the housing 241 to generate a corresponding induced charge on the inner surface of the housing 241, and the housing 241 at this time may serve as another signal output other than the electrode 242. end. Here, it is to be noted that the material of the housing 241 may be set as a metal, or may be provided as a material other than metal; or the housing 241 may be further configured as a two-layer structure, that is, The inner structure of the casing 241 is set to a metal, and then a polymer film material or the like is disposed in addition to the above metal. Here, as long as the housing 241 can be realized as another signal output end, the present invention does not limit the material and structure of the housing 241.
其中，在方案一和方案二的第一种实现方式中，仅设置有一个信号输出端，即电极242作为唯一的信号输出端；而在方案一和方案二的第二种实现方式中，设置有两个信号输出端，分别为电极242以及壳体241。其中，当仅设置一个信号输出端时，即选择电极242作为唯一的信号输出端，电极242与外电路中的接地点共同形成电流回路；当设置两个信号输出端时，即 选择电极242以及壳体241作为信号输出端时，由于电极242以及壳体241这两个电极层之间具有电势差而形成电流回路。In the first implementation manners of the first scheme and the second scheme, only one signal output terminal is disposed, that is, the electrode 242 is the only signal output terminal; and in the second implementation manner of the first scheme and the second scheme, There are two signal outputs, namely an electrode 242 and a housing 241. Wherein, when only one signal output terminal is provided, that is, the electrode 242 is selected as the only signal output terminal, the electrode 242 and the grounding point in the external circuit form a current loop; when two signal output terminals are set, When the electrode 242 and the casing 241 are selected as the signal output ends, a current loop is formed due to a potential difference between the electrode layers 242 and the casing 241.
另外，在方案二的任一实现方式的基础上，本领域技术人员还可以进一步在第二高分子薄膜和第一高分子薄膜之间增设居间薄膜层或居间电极层，从而进一步增加摩擦界面的数量，提升摩擦效果。总之，本发明对摩擦界面的具体数量和实现方式不做限定，本领域技术人员可以灵活设置摩擦界面的形式，只要能够实现摩擦发电的效果即可。In addition, on the basis of any implementation of the second solution, those skilled in the art may further add an intervening film layer or an intervening electrode layer between the second polymer film and the first polymer film, thereby further increasing the friction interface. Quantity, improve friction. In summary, the present invention does not limit the specific number and implementation manner of the friction interface, and those skilled in the art can flexibly set the form of the friction interface as long as the effect of friction power generation can be achieved.
最后，介绍一下气流传感器输出的电信号与其内部的气流的流量和流速之间的换算关系：Finally, introduce the conversion relationship between the electrical signal output by the airflow sensor and the flow and flow rate of the internal airflow:
在获取信号输出端输出的电信号之后，通过对上述电信号中包含的相应数值进行处理来获取气流的流速以及流量。其中，上述电信号包括电压值、频率值等相关的电信号参数。经发明人测量发现，气流的气流流速越大，振膜的振动频率相应越高，则输出的电压值和频率也越大。并且，发明人进一步从测量的数值中发现，气流流速与电压值V以及频率f之间为正比关系，即气流流速与电压值V、气流流速与频率f之间的关系为线性关系，因此，通过获取输出的电压值、频率值以及测量的时间长度便可进一步计算出气流的流速以及流量，从而实现测量气流的流速与流量的目的。其中，上述测量的具体实验数据如表1所示，表1为不同气流流速下测量到的样品输出电信号参数表，项目1和项目2中的具体样品参数不同，因此，在相同气流流速下的测量值也有所不同。由表1可以看出，表1中不同的气流流速与电压值V、气流流速与频率f之间的关系近似呈线性关系。其中，由于测量结果受多个参数的影响，另外，由于实验误差的存在，表1中的数据并没有呈现出严格的线性关系，但是，可以明显看出，无论是在项目1中还是在项目2中，随着气流流速的增大，电压值以及频率值都随之相应地增大。其中，测量样品的一种可选的参数信息如下：样品外壳为金属外壳，直径为6.0mm，振膜与电极的间距(即电极三脚架台阶高度)为1.0mm，振膜厚度为4～6um，振膜为长方形，长度为3.50mm，宽度为1.0mm。 After acquiring the electrical signal outputted from the signal output, the flow rate and flow rate of the airflow are obtained by processing the corresponding values contained in the electrical signal. Wherein, the electrical signal includes an electrical signal parameter related to a voltage value, a frequency value and the like. According to the measurement by the inventors, the larger the flow velocity of the airflow, the higher the vibration frequency of the diaphragm, and the greater the voltage value and frequency of the output. Further, the inventors further found from the measured values that the flow velocity is proportional to the voltage value V and the frequency f, that is, the relationship between the flow velocity and the voltage value V, the flow velocity and the frequency f is linear, therefore, The flow rate and flow rate of the airflow can be further calculated by obtaining the output voltage value, the frequency value, and the measured time length, thereby achieving the purpose of measuring the flow rate and flow rate of the airflow. The specific experimental data of the above measurement are shown in Table 1. Table 1 shows the sample output electric signal parameter table measured under different air flow rates, and the specific sample parameters in items 1 and 2 are different, so at the same air flow rate The measured values are also different. It can be seen from Table 1 that the relationship between the different gas flow rates in Table 1 and the voltage value V, the gas flow rate and the frequency f is approximately linear. Among them, because the measurement results are affected by multiple parameters, in addition, due to the existence of experimental errors, the data in Table 1 does not show a strict linear relationship, but it can be clearly seen that whether in project 1 or in the project In 2, as the flow velocity increases, the voltage value and the frequency value increase accordingly. Among them, an optional parameter information of the measurement sample is as follows: the sample casing is a metal casing, the diameter is 6.0 mm, the distance between the diaphragm and the electrode (ie, the step height of the electrode tripod) is 1.0 mm, and the diaphragm thickness is 4-6 um. The diaphragm is rectangular, with a length of 3.50 mm and a width of 1.0 mm.

由此可见，示例四提供的气流传感器利用摩擦发电原理实现，不仅具有轻便易携的优势，而且制作成本低廉、制作工艺简单，具有实施性强、易组装的特点。同时，在本发明提供的气流传感器的工作过程中，通过在第一高分子薄膜上进一步设置振膜，充分利用振膜自由端在气流作用下产生振动进而产生摩擦效果，以及振膜在振动过程中产生的惯性作用增加摩擦发电过程中的摩擦效果，并通过设置多种方式的摩擦发电方案来获取更加准确和有效的感应信号，提升了信号灵敏度，同时也提高了气流传感器工作的准确性。It can be seen that the airflow sensor provided in the example 4 is realized by the principle of friction power generation, which not only has the advantages of being light and easy to carry, but also has the advantages of low production cost, simple manufacturing process, strong implementation and easy assembly. Meanwhile, in the working process of the airflow sensor provided by the present invention, by further providing a diaphragm on the first polymer film, the free end of the diaphragm is utilized to generate vibration under the action of the airflow, thereby generating a friction effect, and the diaphragm is in the vibration process. The inertia generated in the friction increases the friction effect in the friction generation process, and obtains more accurate and effective induction signals by setting various modes of friction generation schemes, which improves the signal sensitivity and improves the accuracy of the operation of the airflow sensor.

下面对本发明提供的具有吸药量监测功能的雾化器实施例一和实施例二的具体工作原理进行详细说明。为了便于说明，下面以监测用户吸药时间、用户吸药次数和用户吸入药量三种用户吸药信息为例进行说明。The specific working principles of the first embodiment and the second embodiment of the atomizer with the drug absorption monitoring function provided by the present invention are described in detail below. For convenience of explanation, the following three examples of user drug absorption information, such as monitoring user drug taking time, user inhaling frequency, and user inhaling drug volume, are taken as an example.
第一种情况：喷嘴气流监测部件中的喷嘴本体的内部设置有一个气流传感器，雾化器主体中设置有一个与该气流传感器电连接的信号预处理模块。In the first case, an air flow sensor is disposed inside the nozzle body in the nozzle airflow monitoring component, and a signal pre-processing module electrically connected to the airflow sensor is disposed in the atomizer body.
在实施例二中，用户可通过交互功能模块控制电源供给模块与中央控制模块进行连通，从而使中央控制模块开始工作；并且用户还可通过交互功能模块设置所需要监测的用户吸药信息。若雾化器主体中没有设置交互功能模块(如实施例一所示)，则按照预设的用户吸药信息开始工作。In the second embodiment, the user can control the power supply module to communicate with the central control module through the interactive function module, so that the central control module starts working; and the user can also set the user drug absorption information to be monitored through the interactive function module. If the interactive function module is not disposed in the main body of the atomizer (as shown in the first embodiment), the work starts according to the preset user drug absorption information.
当用户吸气时，喷嘴气流监测部件中的喷嘴本体的内部设置的一个气流传感器感应到用户吸气产生的气流作用在其上的压力，并将作用在其上的压力转换为对应的吸气气流压力电信号输出至与该气流传感器对应电连接的信号预处理模块，由该信号预处理模块对该气流传感器输出的吸气气流压力 电信号进行预处理。中央控制模块在接收到该信号预处理模块预处理后的吸气气流压力电信号时，启动中央控制模块内部设置的计时器计时，同时，中央控制模块会分析计算出该吸气气流压力电信号的峰值，从而根据得到的该吸气气流压力电信号的峰值分析计算出用户吸气所产生的气流的流速和流量，进而分析计算出用户第一次吸气时单位时间内用户吸入药量Y1。When the user inhales, an air flow sensor disposed inside the nozzle body in the nozzle airflow monitoring component senses the pressure exerted on the airflow generated by the user's inhalation, and converts the pressure acting thereon into the corresponding inhalation. The airflow pressure electrical signal is output to a signal pre-processing module electrically connected to the airflow sensor, and the signal pre-processing module outputs the inspiratory flow pressure of the airflow sensor The electrical signal is preconditioned. The central control module starts the timer set in the central control module when receiving the inspiratory airflow pressure electric signal preprocessed by the signal preprocessing module, and the central control module analyzes and calculates the inspiratory flow pressure electrical signal. The peak value is obtained, and the flow rate and flow rate of the airflow generated by the user's inhalation are calculated according to the obtained peak value analysis of the inspiratory airflow pressure electric signal, and then the user inhaled dose Y1 per unit time during the first inhalation of the user is calculated and calculated. .
当用户呼气时，喷嘴气流监测部件中的喷嘴本体的内部设置的一个气流传感器感应到用户呼气产生的气流作用在其上的压力，并将作用在其上的压力转换为对应的呼气气流压力电信号输出至与该气流传感器对应电连接的信号预处理模块，由该信号预处理模块对该气流传感器输出的呼气气流压力电信号进行预处理。中央控制模块在接收到该信号预处理模块预处理后的呼气气流压力电信号时，停止中央控制模块内部设置的计时器计时，得到第一计时时间X1(即为用户第一次吸气的时间)，之后将中央控制模块内部设置的计时器清零；同时，启动中央控制模块内部设置的计数器进行计数，得到第一吸药次数C1。另外，若用户没有呼气过程，即也没有用户吸气或呼气产生的气流作用在喷嘴气流监测部件中的喷嘴本体的内部设置的一个气流传感器上，喷嘴气流监测部件中的喷嘴本体的内部设置的一个气流传感器为了恢复到起始状态，也会输出一个与用户呼气时该气流传感器输出的呼气气流压力电信号相类似的起始状态电信号，即用户呼气时该气流传感器输出的呼气气流压力电信号与起始状态电信号方向相同，因此，其工作原理与上述有用户呼气产生的气流作用在喷嘴气流监测部件中的喷嘴本体的内部设置的一个气流传感器上的工作原理相同，此处不再赘述。When the user exhales, an air flow sensor disposed inside the nozzle body in the nozzle airflow monitoring component senses the pressure exerted on the airflow generated by the user's exhalation, and converts the pressure acting thereon to the corresponding exhalation. The airflow pressure electrical signal is output to a signal pre-processing module electrically connected to the airflow sensor, and the signal pre-processing module pre-processes the expiratory airflow pressure electrical signal output by the airflow sensor. When receiving the exhalation airflow pressure electric signal preprocessed by the signal preprocessing module, the central control module stops the timer set in the central control module to obtain the first timing time X1 (ie, the first inhalation of the user) Time), then clear the timer set in the central control module; at the same time, start the counter set in the central control module to count, get the first dose C1. In addition, if the user does not have an exhalation process, that is, no air flow generated by the user inhaling or exhaling acts on an air flow sensor disposed inside the nozzle body in the nozzle airflow monitoring member, the inside of the nozzle body in the nozzle airflow monitoring member In order to restore the initial state, an airflow sensor is also provided with an initial state electrical signal similar to the expiratory flow pressure electrical signal output by the airflow sensor when the user exhales, that is, the airflow sensor output when the user exhales. The expiratory flow pressure electrical signal has the same direction as the initial state electrical signal, and therefore, the working principle and the above-mentioned airflow generated by the user's exhalation act on an airflow sensor disposed inside the nozzle body in the nozzle airflow monitoring component. The principle is the same and will not be described here.
中央控制模块会判断在预设时间间隔内是否再次接收到该信号预处理模块预处理后的吸气气流压力电信号。其中，本领域技术人员可根据实际需要设置预设时间间隔，此处不作限定。例如，预设时间间隔可为1s。如果判断得到在预设时间间隔内再次接收到了该信号预处理模块预处理后的吸气气流压力电信号，说明用户第二次吸气，此时，中央控制模块启动其内部设置的计时器计时，同时，中央控制模块会分析计算出该吸气气流压力电信号的峰值，从而根据得到的该吸气气流压力电信号的峰值分析计算出用户此次吸气所产生的气流的流速和流量，进而分析计算出用户第二次吸气时单位时 间内用户吸入药量Y2。在中央控制模块接收到该信号预处理模块预处理后的呼气气流压力电信号时，中央控制模块停止其内部设置的计时器计时，得到第二计时时间X2(即为用户第二次吸气的时间)，之后将中央控制模块内部设置的计时器清零；同时，中央控制模块启动其内部设置的计数器累加计数，得到第二吸药次数C2。The central control module determines whether the inspiratory flow pressure electrical signal preprocessed by the signal preprocessing module is received again within the preset time interval. The preset time interval may be set by a person skilled in the art according to actual needs, which is not limited herein. For example, the preset time interval can be 1 s. If it is determined that the inspiratory airflow pressure electric signal preprocessed by the signal preprocessing module is received again within the preset time interval, the user inhales for the second time, and at this time, the central control module starts the timer setting of its internal setting. At the same time, the central control module analyzes and calculates the peak value of the inspiratory flow pressure electrical signal, and calculates the flow rate and flow rate of the airflow generated by the user's inhalation according to the obtained peak analysis of the inspiratory flow pressure electrical signal. Then analyze and calculate the unit time when the user inhales for the second time. The user inhaled the dose Y2. When the central control module receives the expiratory airflow pressure electrical signal preprocessed by the signal preprocessing module, the central control module stops the timer set by its internal timer, and obtains the second timing time X2 (ie, the user inhales for the second time) After the time), the timer set inside the central control module is cleared. At the same time, the central control module starts the counter of its internal setting and counts up to obtain the second number of times of suction C2.
中央控制模块会判断在预设时间间隔内是否还能够接收到该信号预处理模块预处理后的吸气气流压力电信号。若是，则中央控制模块再次启动其内部设置的计时器计时，重复上述过程；若否，则中央控制模块分析计算得到总的用户吸药时间X，总的用户吸药次数C为C2(即2次)，总的用户吸入药量S，从而得到用户吸药时间信息、用户吸药次数信息和用户吸入药量信息。其中，X＝X1+X2，S＝X1×Y1+X2×Y2。The central control module determines whether the inspiratory flow pressure electrical signal preprocessed by the signal pre-processing module can also be received within the preset time interval. If yes, the central control module starts the timer set by its internal setting again, and repeats the above process; if not, the central control module analyzes and calculates the total user drug taking time X, and the total user drug intake number C is C2 (ie 2 The total user inhales the dose S, thereby obtaining the user's drug taking time information, the user's drug taking times information, and the user's inhaled drug amount information. Where X = X1 + X2, S = X1 × Y1 + X2 × Y2.
应当注意的是，用户吸气时喷嘴气流监测部件中的喷嘴本体的内部设置的一个气流传感器输出的吸气气流压力电信号的峰值与用户吸气所产生的气流的流速和流量以及单位时间内用户吸入药量Y都是一一对应的。其中，用户吸气时喷嘴气流监测部件中的喷嘴本体的内部设置的一个气流传感器输出的吸气气流压力电信号的峰值与用户吸气所产生的气流的流速和流量之间的对应关系以及用户吸气所产生的气流的流速和流量与单位时间内用户吸入药量Y之间的对应关系可由生产具有吸药量监测功能的雾化器的生产厂家预先设定。It should be noted that the peak value of the inspiratory flow pressure electric signal output by an air flow sensor disposed inside the nozzle body in the nozzle airflow monitoring part when inhaling by the user and the flow rate and flow rate of the airflow generated by the user inhaling and the unit time The user inhaled dose Y is one-to-one correspondence. Wherein, when the user inhales, the correspondence between the peak value of the inspiratory flow pressure electric signal output by an air flow sensor disposed inside the nozzle body in the nozzle airflow monitoring component and the flow rate and flow rate of the airflow generated by the user inhaling and the user The correspondence between the flow rate and flow rate of the airflow generated by the inhalation and the user's inhaled dose Y per unit time can be preset by the manufacturer who produces the atomizer having the drug absorption monitoring function.
第二种情况：喷嘴气流监测部件中的喷嘴本体的内部设置有多个气流传感器，雾化器主体中设置有多个信号预处理模块，该多个信号预处理模块与喷嘴气流监测部件中的喷嘴本体的内部设置的多个气流传感器数量相同，且该多个信号预处理模块与该多个气流传感器一一对应电连接，同时，该多个信号预处理模块还分别与雾化器主体中的中央控制模块电连接。In the second case, the inside of the nozzle body in the nozzle airflow monitoring component is provided with a plurality of airflow sensors, and the atomizer body is provided with a plurality of signal preprocessing modules, and the plurality of signal preprocessing modules and the nozzle airflow monitoring component The number of the plurality of airflow sensors disposed in the nozzle body is the same, and the plurality of signal pre-processing modules are electrically connected to the plurality of airflow sensors in one-to-one correspondence, and the plurality of signal pre-processing modules are also respectively associated with the atomizer body The central control module is electrically connected.
在实施例二中，用户可通过交互功能模块控制电源供给模块与中央控制模块进行连通，从而使中央控制模块开始工作；并且用户还可通过交互功能模块设置所需要监测的用户吸药信息。若雾化器主体中没有设置交互功能模块(如实施例一所示)，则按照预设的用户吸药信息开始工作。In the second embodiment, the user can control the power supply module to communicate with the central control module through the interactive function module, so that the central control module starts working; and the user can also set the user drug absorption information to be monitored through the interactive function module. If the interactive function module is not disposed in the main body of the atomizer (as shown in the first embodiment), the work starts according to the preset user drug absorption information.
当用户吸气时，喷嘴气流监测部件中的喷嘴本体的内部设置的多个气流 传感器感应到用户吸气产生的气流作用在其上的压力，并将作用在其上的压力转换为对应的吸气气流压力电信号输出至与该多个气流传感器一一对应电连接的该多个信号预处理模块，由该多个信号预处理模块对该多个气流传感器输出的吸气气流压力电信号进行预处理。中央控制模块在接收到该多个吸气气流压力电信号时，中央控制模块会根据该多个吸气气流压力电信号中接收到的第一个吸气气流压力电信号启动其内部设置的计时器计时，同时，中央控制模块会分别分析计算出该多个吸气气流压力电信号的峰值，将该多个吸气气流压力电信号的峰值相加求出平均值，得到最终的吸气气流压力电信号的峰值，从而根据得到的最终的吸气气流压力电信号的峰值分析计算出用户吸气所产生的气流的流速和流量，进而分析计算出用户第一次吸气时单位时间内用户吸入药量Y1。其中，为了便于在下文中进行描述，将上述输出第一个吸气气流压力电信号的气流传感器称为气流传感器A。When the user inhales, the plurality of airflows disposed inside the nozzle body in the nozzle airflow monitoring component The sensor senses the pressure exerted by the airflow generated by the user's inhalation, and converts the pressure acting thereon into a corresponding inspiratory flow pressure electrical signal output to the one that is electrically connected to the plurality of airflow sensors in one-to-one correspondence The signal pre-processing module preprocesses the inspiratory flow pressure electrical signals output by the plurality of airflow sensors by the plurality of signal pre-processing modules. When the central control module receives the plurality of inspiratory flow pressure electrical signals, the central control module initiates the internal setting timing according to the first inspiratory flow pressure electrical signal received in the plurality of inspiratory flow pressure electrical signals. At the same time, the central control module separately analyzes and calculates the peak value of the plurality of inspiratory flow pressure electrical signals, adds the peaks of the plurality of inspiratory flow pressure electrical signals to obtain an average value, and obtains the final inspiratory flow. The peak value of the pressure electric signal, thereby calculating the flow rate and flow rate of the airflow generated by the user's inhalation according to the peak analysis of the obtained final inspiratory flow pressure electrical signal, and then analyzing and calculating the user's first inhalation time per unit time Inhaled dose Y1. Here, for convenience of description below, the above-described air flow sensor that outputs the first inspiratory flow pressure electric signal is referred to as the air flow sensor A.
当用户呼气时，喷嘴气流监测部件中的喷嘴本体的内部设置的多个气流传感器感应到用户呼气产生的气流作用在其上的压力，并将作用在其上的压力转换为对应的呼气气流压力电信号输出至与该多个气流传感器一一对应电连接的该多个信号预处理模块，由该多个信号预处理模块对该多个气流传感器输出的呼气气流压力电信号进行预处理。此时，中央控制模块依然会根据气流传感器A输出的呼气气流压力电信号停止其内部设置的计时器计时，得到第一计时时间X1(即为用户第一次吸气的时间)，之后将中央控制模块内部设置的计时器清零；同时，启动中央控制模块内部设置的计数器计数，得到第一吸药次数C1。另外，若用户没有呼气过程，也即没有用户吸气或呼气产生的气流作用在气流传感器A上，气流传感器A为了恢复到起始状态，也会输出一个与用户呼气时气流传感器A输出的呼气气流压力电信号相类似的起始状态电信号，即用户呼气时气流传感器A输出的呼气气流压力电信号与起始状态电信号方向相同，因此，其工作原理与上述有用户呼气产生的气流作用在气流传感器A上的工作原理相同，此处不再赘述。When the user exhales, the plurality of airflow sensors disposed inside the nozzle body in the nozzle airflow monitoring component sense the pressure exerted on the airflow generated by the user's exhalation, and convert the pressure acting thereon into a corresponding call. The gas flow pressure electric signal is output to the plurality of signal pre-processing modules electrically connected to the plurality of air flow sensors in one-to-one correspondence, and the plurality of signal pre-processing modules perform the expiratory flow pressure electric signals output by the plurality of air flow sensors Pretreatment. At this time, the central control module will stop the timer set by its internal airflow pressure electric signal according to the airflow sensor A, and obtain the first timing time X1 (that is, the time for the user to inhale for the first time), and then The timer set in the central control module is cleared. At the same time, the counter set in the central control module is started to count, and the first dose C1 is obtained. In addition, if the user does not have an exhalation process, that is, no airflow generated by the user inhaling or exhaling acts on the airflow sensor A, the airflow sensor A also outputs an airflow sensor A when exhaling with the user in order to return to the initial state. The output expiratory airflow pressure electrical signal is similar to the initial state electrical signal, that is, the expiratory airflow pressure electrical signal output by the airflow sensor A when the user exhales is in the same direction as the initial state electrical signal, therefore, the working principle and the above are The airflow generated by the user's exhalation works the same on the airflow sensor A, and will not be described here.
中央控制模块会判断在预设时间间隔内是否再次接收到预处理后的用户吸气时气流传感器A输出的吸气气流压力电信号。其中，本领域技术人员可根据实际需要设置预设时间间隔，此处不作限定。例如，预设时间间隔 可为1s。如果判断得到在预设时间间隔内再次接收到了用户吸气时气流传感器A输出的吸气气流压力电信号，说明用户第二次吸气，此时，中央控制模块启动其内部设置的计时器计时，同时，中央控制模块也会接收到经过预处理后的其它气流传感器对应输出的吸气气流压力电信号，此时，中央控制模块分别分析计算出所有的气流传感器对应输出的多个吸气气流压力电信号的峰值，将接收到的所有吸气气流压力电信号的峰值相加求出平均值，得到最终的吸气气流压力电信号的峰值，从而根据得到的最终的吸气气流压力电信号的峰值分析计算出用户吸气所产生的气流的流速和流量，进而分析计算出用户第二次吸气时单位时间内用户吸入药量Y2。在中央控制模块接收到经过预处理后的用户呼气时气流传感器A输出的呼气气流压力电信号时，中央控制模块停止其内部设置的计时器计时，得到第二计时时间X2(即为用户第二次吸气的时间)，之后将中央控制模块内部设置的计时器清零；同时，中央控制模块启动其内部设置的计数器累加计数，得到第二吸药次数C2。The central control module determines whether the inspiratory flow pressure electrical signal output by the airflow sensor A when the pre-processed user inhales is received again in the preset time interval. The preset time interval may be set by a person skilled in the art according to actual needs, which is not limited herein. For example, preset time interval Can be 1s. If it is judged that the inspiratory airflow pressure electric signal output by the airflow sensor A is received again during the preset time interval, the user inhales for the second time, at this time, the central control module starts the timer setting of its internal setting. At the same time, the central control module also receives the inspiratory flow pressure electrical signals corresponding to the output of the other airflow sensors after the pre-processing, and at this time, the central control module separately analyzes and calculates the plurality of inspiratory airflows corresponding to the output of all the airflow sensors. The peak value of the pressure electric signal is added to obtain the average value of the pressure signals of all the inspiratory gas flow signals, and the average value of the final inspiratory gas flow pressure electric signal is obtained, thereby obtaining the electric signal according to the obtained final inspiratory gas flow pressure. The peak analysis calculates the flow rate and flow rate of the airflow generated by the user's inhalation, and then analyzes and calculates the user's inhaled dose Y2 per unit time when the user inhales for the second time. When the central control module receives the expiratory airflow pressure electric signal output by the airflow sensor A when the pre-processed user exhales, the central control module stops the timer set by its internal setting, and obtains the second timing time X2 (ie, the user After the second inhalation time, the timer set inside the central control module is cleared. At the same time, the central control module starts the counter counting of its internal setting to obtain the second sampling frequency C2.
中央控制模块会判断在预设时间间隔内是否还能够接收到经过预处理后的用户吸气时气流传感器A输出的吸气气流压力电信号。若是，则中央控制模块再次启动其内部设置的计时器进行计时，重复上述过程；若否，则中央控制模块分析计算得到总的用户吸药时间X，总的用户吸药次数C为C2(即2次)，总的用户吸入药量S，从而得到用户吸药时间信息、用户吸药次数信息和用户吸入药量信息。其中，X＝X1+X2，S＝X1×Y1+X2×Y2。The central control module determines whether the inspiratory flow pressure electrical signal output by the airflow sensor A when the pre-processed user inhales is still received in the preset time interval. If yes, the central control module starts its internal setting timer again to repeat the above process; if not, the central control module analyzes and calculates the total user drug intake time X, and the total user drug intake number C is C2 (ie 2 times), the total user inhales the dose S, thereby obtaining the user's drug taking time information, the user's drug taking times information, and the user's inhaled drug amount information. Where X = X1 + X2, S = X1 × Y1 + X2 × Y2.
应当注意的是，将用户吸气时喷嘴气流监测部件中的喷嘴本体的内部设置的多个气流传感器输出的吸气气流压力电信号的峰值相加求出的平均值与用户吸气所产生的气流的流速和流量以及单位时间内用户吸入药量Y都是一一对应的。其中，将用户吸气时喷嘴气流监测部件中的喷嘴本体的内部设置的多个气流传感器输出的吸气气流压力电信号的峰值相加求出的平均值与用户吸气所产生的气流的流速和流量之间的对应关系以及用户吸气所产生的气流的流速和流量与单位时间内用户吸入药量Y之间的对应关系可由生产具有吸药量监测功能的雾化器的生产厂家预先设定。It should be noted that the average value obtained by adding the peaks of the inspiratory flow pressure electric signals outputted by the plurality of airflow sensors provided inside the nozzle body in the nozzle airflow monitoring member when inhaling by the user is generated by the user's inhalation. The flow rate and flow rate of the airflow and the user's inhaled dose Y per unit time are one-to-one correspondence. Wherein, the average value obtained by adding the peaks of the inspiratory flow pressure electrical signals outputted by the plurality of airflow sensors provided inside the nozzle body in the nozzle airflow monitoring component when inhaling by the user and the flow velocity of the airflow generated by the user inhaling The correspondence between the flow rate and the flow rate and the flow rate of the airflow generated by the user's inhalation and the user's inhaled dose Y per unit time can be pre-set by the manufacturer who produces the atomizer with the drug absorption monitoring function. set.
此外，更应当注意的是，在上述两种情况中，当用户吸气产生的气流作 用在一个摩擦发电式气流传感器上时，随着施加在其上的气流压力的逐渐增大，该摩擦发电式气流传感器输出的吸气气流压力电信号也会逐渐增大，但是，当施加在该摩擦发电式气流传感器上的吸气气流压力达到稳定状态(如施加在该摩擦发电式气流传感器上的吸气气流压力恒定不变)时，该摩擦发电式气流传感器输出的吸气气流压力电信号会逐渐减小，直到恢复到原始状态(如吸气气流压力电信号恢复为0)，并持续保持在该原始状态；当用户呼气产生的气流施加在该摩擦发电式气流传感器上的呼气气流压力或施加在该摩擦发电式气流传感器上的气流压力为零时，上述原始状态将被改变，此时，该摩擦发电式气流传感器会输出一个与吸气气流压力电信号(如正向脉冲电信号)相反的呼气气流压力电信号(如负向脉冲电信号)或起始状态电信号(如负向脉冲电信号)，因此，为了准确地监测用户吸气的时间，从而准确地监测用户吸入药量，这就需要对用户呼气产生的气流作用在该摩擦发电式气流传感器上的呼气气流压力电信号或该摩擦发电式气流传感器为了恢复到起始状态而输出的起始状态电信号进行监测，从而确定用户完成一次吸气的终止时间。In addition, it should be noted that in the above two cases, when the user inhales the airflow generated When used on a friction-generating airflow sensor, as the pressure of the airflow applied thereto is gradually increased, the electric signal of the inspiratory flow output from the frictional-generation airflow sensor is gradually increased, but when applied to When the pressure of the intake airflow on the frictional power flow sensor reaches a steady state (for example, the pressure of the intake airflow applied to the frictional power flow sensor is constant), the intake airflow pressure of the frictional power flow sensor is The signal will gradually decrease until it returns to the original state (such as the inspiratory airflow pressure electrical signal returns to 0) and continues to remain in the original state; when the airflow generated by the user's exhalation is applied to the frictional generating airflow sensor When the gas flow pressure or the gas flow pressure applied to the frictional power generation air flow sensor is zero, the original state will be changed. At this time, the frictional power flow sensor outputs a pressure electric signal with the intake air flow (eg, positive Pulse electrical signal) the opposite of the expiratory flow pressure electrical signal (such as the negative impulse electrical signal) or the initial state electrical signal (such as the negative impulse telecommunications No.) Therefore, in order to accurately monitor the user's inhalation time, thereby accurately monitoring the user's inhaled dose, this requires an expiratory flow pressure electrical signal that acts on the frictional-generation airflow sensor by the airflow generated by the user's exhalation. Or the frictional power type airflow sensor monitors the initial state electrical signal outputted in order to return to the initial state, thereby determining the end time of the user to complete an inhalation.
