如下为本发明的优选实施例，其仅用对本发明的解释而并非限制。The following are preferred embodiments of the invention, which are merely illustrative of the invention and are not limiting.
参见图1和图2，本发明提供的呼气阀包括阀口1、遮挡件、阀体板、电磁件和磁铁10，所述遮挡件包括膜片2和膜片挡片3，所述遮挡件和电磁件连接，所述电磁件包括顶芯7和顶针4，顶芯7上设置有线圈8。所述膜片2为硅胶膜片，所述膜片挡片3为金属薄板。Referring to FIG. 1 and FIG. 2, the exhalation valve provided by the present invention comprises a valve port 1, a shielding member, a valve body plate, an electromagnetic member and a
所述呼气阀还包括导向套，所述顶针4的一端和遮挡件连接，另一端伸入导向套9内，所述线圈缠绕于顶芯7上。顶针3和顶芯7固定在一起。顶针4和顶芯7与线圈8可以同时以阀体板5、导向套9做导向在图示左右方向上运动。所述呼气阀还进包括弹簧6，所述弹簧6设置于顶芯和阀体板之间。The exhalation valve further includes a guiding sleeve, one end of the thimble 4 is connected to the shielding member, and the other end extends into the guiding sleeve 9, and the coil is wound around the top core 7. The thimble 3 and the top core 7 are fixed together. The ejector pin 4 and the top core 7 and the coil 8 can be simultaneously guided by the valve body plate 5 and the guide sleeve 9 to move in the left-right direction of the drawing. The exhalation valve also includes a
由洛伦兹力定律，通电线圈在磁场中可以产生力，当在吸气阶段时，呼气阀需关闭，则在线圈8内通上指定方向的电流，而通电线圈在磁铁10的磁场作用下，产生使其向左运动的力，当此力克服弹簧6压缩的作用力后，可使得顶针4顶着膜片挡片3并带动膜片2一起向左，而将阀口1的口端封住，使得呼吸机提供的气体进入病人肺内。而在吸气相结束，病人需要呼气时，断开线圈8的电，同时线圈8产生的安培力消失，弹簧6被压缩的力消失，从而得到舒张，其左端由于被阀体板5挡着，只能其右端推动件顶针、顶芯7、线圈8一起向右运动，主动将呼气阀的阀口打开，不需病人的呼气推动膜片2，没有阻力，顺利排气，减小病人的呼吸功，提高病人舒适度，有助于缓解病情，提高治愈率。According to Lorentz's law, the energized coil can generate a force in the magnetic field. When the exhalation valve needs to be closed during the inhalation phase, the current in the specified direction is passed through the coil 8, and the energized coil acts on the magnetic field of the
显然的，所述线圈通电时，线圈在磁场中运动带动电磁件向呼吸阀口运动，从而使遮挡件闭合阀口，并压缩弹簧6；所述线圈断电时，相应的电磁力消失，弹簧6回复原状，从而打开呼气阀的阀口。当然此处也可以设计为所述线圈通以反方向的电流，使线圈在呼气和吸气时向不同的方向运动，从而不借助弹性件实现阀口的开关。
Obviously, when the coil is energized, the movement of the coil in the magnetic field drives the electromagnetic component to move to the breathing valve port, so that the shielding member closes the valve port and compresses the
对于该装置，也可以将线圈设置在电磁体之外，而在电磁体内设置磁铁，该磁铁在线圈通电时受到磁场力的作用，其也可以实现带动遮挡件从而实现阀口的打开或关闭。For the device, the coil may be disposed outside the electromagnet, and a magnet is disposed in the electromagnet. The magnet is subjected to a magnetic field force when the coil is energized, and it may also be configured to drive the shutter to open or close the valve port.
为了增强线圈的磁场，可以针对性的设置软磁体。而电磁体中也可以不设置单独的磁铁，而设置软磁体，其也可以通过通电与否实现阀口的打开和关闭。In order to enhance the magnetic field of the coil, a soft magnet can be set in a targeted manner. In the electromagnet, a separate magnet can be omitted, and a soft magnet can be provided, which can also open and close the valve port by energizing or not.
