In one possible embodiment, the bottom of the lower valve body 3 is screwed with a bottle 5.

In one possible embodiment, as shown in fig. 3, the upper valve body 2 is provided with an air outlet pipe iron core 1 and a driving coil 12, and an air outlet through hole 21 is formed on the surface of the inner cavity of the upper valve body, so that when the valve core is opened, the inner air flow flows out through the through hole. The upper valve body 2 and the lower valve body 3 are clamped by a mode of installing a buckle 31, and a sealing ring 6 is arranged on the clamping surface of the upper valve body and the lower valve body for ensuring sealing. The elastic valve core 7 and the air outlet valve port piece 9 are installed and blocked in the upper valve body 2 and the lower valve body 3 in the process of mutual matching. A fixed ring magnet 10 and a ring magnet fixing member 11 are mounted on the inner tube of the lower valve body 3.
In one possible embodiment, as shown in fig. 4 (a) and fig. 4 (b), the valve consists of an elastic valve core 7 and a movable cylindrical magnet 8, wherein the cylindrical magnet is embedded in an elastic valve core inner cavity 74 of the elastic valve core 7, and the elastic valve core 7 is made of silica gel or a flexible material similar to the silica gel. The elastic valve core 7 has a complex structure, and needs to be injection molded by a mold, and the fixing edge 71 of the elastic valve core is used for installing and fixing the whole valve core assembly; the sealing umbrella edge 72 is of an umbrella-shaped structure and is used for closing and opening the outlet valve; the vibration film 73 imparts a movable property to the elastic valve body 7, and when the columnar magnet is forced inside, the vibration film 73 can vibrate in a bending manner up and down in the thickness direction.
In one possible embodiment, as shown in fig. 5 (a) and 5 (b), the elastic valve element 7 cooperates with the air outlet valve port member 9 to function as an outlet switching valve. The collar 91 of the outlet valve port member 9 secures the resilient valve element 7 to the lower valve body 3 by cooperating with the securing rim 71 of the resilient valve element 7. When the elastic valve core 7 is acted by downward force, the sealing umbrella edge 72 blocks the air outlet valve port 92, and the air outlet valve is closed. When the elastic valve core 7 is acted by upward force, the sealing umbrella edge 72 releases the air outlet valve port 92, and the air outlet valve is opened.
Firstly, the invention adopts a single moving part and a single driving coil 12 to realize the opening and closing control functions of two valve ports, and the core of the invention is an elastic valve core 7 embedded with a cylindrical magnet, the head part of the elastic valve core 7 is umbrella-shaped, and the tail part of the elastic valve core is an annular plane. The umbrella-shaped head part is matched with the air outlet valve core part to realize the function of an air outlet valve, and the annular surface at the tail part is matched with the air inlet valve silica gel sealing part and the valve core part in the bottle to realize the function of an air inlet valve. The originality of the valve is that the two valves are opened and closed by the same moving piece. A single coil 12 drives a single moving member to achieve simultaneous opening or closing of two valve ports.
Secondly, the movable valve core member adopts a structure of a vibrating membrane 73, when the valve core is switched to a steady state, the membrane is bent to act like a spring, and a reverse force is applied to the movable member, so that the movable assembly is decelerated, and collision noise is effectively reduced. In addition, the air inlet pipeline and the air outlet pipeline are isolated, the air inlet pipeline is arranged at the lower part of the film, and the air outlet pipeline is arranged at the upper part of the film.
Thirdly, the invention realizes the maintenance of the switching on/off of the two valve ports by only using one bistable structure. The electromagnetic driving portion includes: a fixed coil 12 and its internal iron core, a ring magnet fixed in the bottle and an umbrella-shaped elastic valve core 7 with embedded magnet. Wherein the core in the coil 12 is used to attract the moving magnet to form a steady state in the valve open condition, and the stationary ring magnet 10 in the jar is used to attract the moving assembly to form a steady state in the valve closed condition, the structure is thus a bistable structure. In the working process, the coil 12 is electrified and the direction of the current flowing into the coil 12 is controlled, so that attractive force and repulsive force on the moving assembly can be respectively generated. Attractive force is used to open the valve and repulsive force is used to close the valve. Due to the bistable structure, the moving assembly does not require the driving force of the coil 12 to maintain its state once it has moved to a steady state position. Thus, the present invention can realize long-time opening and closing of the valve without requiring long-time power supply.
Fourth, the invention realizes the noise reduction effect of the bistable valve. Bistable valves are very prone to large impact noise due to the relatively sharp energy transitions during state switching. The invention structurally has three noise reduction designs: firstly, the rigid moving magnet is wholly embedded in a flexible structure, so that the flexible structure can effectively buffer during collision, and the thickness of the flexible structure can be adjusted to reduce noise efficiently; when the valve is closed, the umbrella part of the moving assembly is contacted with the air outlet valve core piece before the tail part of the moving assembly impacts the valve core in the bottle, and the closing impact force of the moving assembly is effectively slowed down in the gradual closing process of the umbrella valve, so that the noise reduction effect is realized; and thirdly, the movable valve core piece adopts a structure of a vibrating membrane 73, when the valve core is switched to a steady state, the membrane is bent to act like a spring, and a reverse force is applied to the movable piece, so that a movable assembly is decelerated, and collision noise is effectively reduced.
Aiming at the problems of complex structure, high assembly cost, large working noise and the like of the traditional electromagnetic bottle valve, the invention realizes the control function of two valves by utilizing the single bistable structure formed by the single coil 12 and the single moving part, not only maintains the low power consumption characteristic of the traditional bottle valve, but also has more exquisite structure and reliable performance. The invention greatly reduces the material and assembly cost and realizes the mute function, and has great application potential in the field of comfortable pneumatic systems.
Working principle: as shown in fig. 6, fig. 6 (a) is in a closed state, fig. 6 (b) is in an open state, the direction of the arrow in the drawing is in the direction of gas flow, the elastic valve core 7 is in an initial state and is tightly attached to the lower valve body 3 downwards under the suction force of the fixed ring magnet 10, at this time, the channel of the gas flow from the gas inlet pipe 4 into the bottle is closed, and the channel of the gas flow from the bottle to the outside through the gas outlet valve port 92 is also closed by the sealing umbrella rim 72, at this time, the valve is in a closed state. The driving coil 12 is electrified with a certain forward current, the valve core component moves upwards under the action of a magnetic field and is sucked by the iron core of the air outlet valve, then the current is removed, the elastic valve core 7 is sucked on the iron core and still keeps an open state, at the moment, air flow is pumped in from the air inlet pipe 4, enters the bottle through the air inlet valve port and the inner pipe of the lower valve body 3, essence gas in the bottle passes through the air outlet valve port piece 9 and the overflow hole of the upper valve body, and finally is blown out of the bottle from the inner hole of the iron core 1 of the air outlet pipe; when the cylinder valve needs to be closed again, current in the opposite direction to the previous direction is conducted to the coil 12, at this time, the coil 12 applies repulsive force to the elastic valve core 7, so that the elastic valve core 7 moves downwards until the elastic valve core 7 is attracted by the fixed annular magnet 10 to reach the closed steady-state position, at this time, both the air inlet valve port of the lower valve body 3 and the air outlet valve port 92 of the air outlet valve port member 9 are blocked, the valve is closed again, and the valve can still maintain the closed state after the coil 12 is powered off.
The foregoing is a further detailed description of the invention in connection with the preferred embodiments, and it is not intended that the invention be limited to the specific embodiments described. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the invention, and these should be considered to be within the scope of the invention.
