The air supplying end <NUM> is provided with an air supplying port matched with the air collecting chamber. The sensing end <NUM> is provided with a sensing diaphragm and an air outlet port communicated with the gas collecting chamber. That is, the air supplying port, the gas collecting chamber and the air outlet port are sequentially connected to form an internal air passage of the pneumatic switch <NUM>. Ambient air enters the air collecting chamber through the air supplying port, then flow out through the air outlet port, driving the sensing diaphragm to deform during the outflow process, thus generating an electrical signal and transmitting the electrical signal to the power supplying main body <NUM>. In practice, the pneumatic switch <NUM> could be an integrated pressure sensor, in which a micro control circuit is integrated, so that the power supplying main body <NUM> does not need to be configured with control elements, and investment cost on equipment can be reduced. Of course, the pneumatic switch <NUM> can adopt a non-integrated pressure sensor. By setting a control element in the power supplying main body <NUM>, the pneumatic switch <NUM> is electrically connected to the control element to transmit electrical signals.

In some embodiments, as shown in <FIG>, <FIG> and <FIG>, the shape of the seal seat <NUM> matches the shape of the mounting chamber <NUM>. When the seal seat <NUM> is accommodated in the mounting chamber <NUM>, the peripheral part of the seal seat <NUM> is elastically abutted against the wall of the mounting chamber <NUM> to fill the gap between the seal seat <NUM> and the mounting chamber <NUM>, and prevent ambient air from flowing through the mounting chamber <NUM> and entering the power supplying main body <NUM> through the gap. The seal seat <NUM> is provided with a through-hole for mounting <NUM> for mounting the pneumatic switch <NUM>. The through-hole for mounting <NUM> comprise a first end <NUM> and a second end <NUM>. Correspondingly, one end of the wall of the mounting chamber <NUM> is provided with an inlet hole <NUM> which communicate the first end <NUM> with ambient air, and the other end is provided with the vent hole <NUM> which communicate the second end <NUM> with ambient air. The pneumatic switch <NUM> is accommodated in the through-hole for mounting <NUM>, and the air supplying end <NUM> communicates with the first end <NUM>, and the sensing end <NUM> communicates with the second end <NUM>. In this way, ambient air, the air inlet hole <NUM>, the first end <NUM>, the air supplying end <NUM>, the air collecting chamber of the pneumatic switch <NUM>, the sensing end <NUM>, the second end <NUM>, the vent hole <NUM> and the mounting part (ambient air) communicate in turn, thus forming the triggering channel of the pneumatic switch <NUM>. In practice, the sensing end <NUM> can be completely exposed to the second end <NUM>; or partly exposed to the second end <NUM>.

In some embodiments, as shown in <FIG>, <FIG> and <FIG>, the adjusting element <NUM> comprises a stop block <NUM> and a rotating shaft <NUM>. The stop block <NUM> is accommodated in the mounting chamber <NUM> and is attached to one side of the second end <NUM> of the seal seat <NUM> with the through-hole for mounting <NUM>. Correspondingly, there is a gap between the side of the seal seat <NUM> with the second end <NUM> and the wall of the mounting chamber <NUM>. The stop block <NUM> is accommodated in the gap. The thickness of the stop block <NUM> is less than or equal to the width of the gap. Preferably, the thickness of the stop block <NUM> is equal to the width of the gap, that is, one side of the stop block <NUM> is attached to the seal seat <NUM>, and the other side is attached to the wall of the mounting chamber <NUM>. The stop block <NUM> is limited by the gap to prevent displacement of the stop block <NUM> along the axial direction of the rotating shaft <NUM>. In practice, a limit boss can also be arranged on the stop block <NUM>, and a matching limit groove can be arranged on the chamber wall forming the gap. The displacement of the stop block <NUM> along the direction of vertical rotating shaft can be limited by clamping the limit boss into the limit groove.

In some embodiments, the rotating shaft <NUM> rotatably pass through the power supplying main body <NUM>, and one end of the rotating shaft <NUM> is fixedly connected to the side of the stop block <NUM> away from the seal seat <NUM>, and the other end extends out of the power supplying main body <NUM> for user operation. Correspondingly, the power supplying main body <NUM> is provided with a rotation hole <NUM> matched with the rotating shaft <NUM>. The rotating shaft <NUM> passes through the rotation hole <NUM> and can rotate with respect to the rotation hole <NUM>. Furthermore, the peripheral part of the rotating shaft <NUM> is convexly provided with a limit bump <NUM>, and the inner wall of the rotation hole <NUM> is provided with an annular clearance groove <NUM> along the circumferential direction. The limit bump <NUM> is accommodated in the clearance groove <NUM> and can rotate along the circumferential direction of the clearance groove <NUM>. The matching between the limiting bump <NUM> and the clearance groove <NUM> not only limit the rotating shaft <NUM> and prevent the displacement of the rotating shaft <NUM> along the axial direction, but also guide the rotation of the rotating shaft <NUM>.

When the rotating shaft <NUM> rotates under force, the stop block <NUM> is driven by the rotating shaft <NUM> to rotate with respect to the seal seat <NUM>. When the stop block <NUM> rotates to the position where the first end <NUM> of the through-hole for mounting <NUM> is blocked, the sensing end <NUM> is blocked, thus separate with the vent hole <NUM>, so that the air at the sensing end <NUM> cannot enter into ambient air, and the sensing end <NUM> cannot be driven to produce deformation. At this time, the pneumatic switch <NUM> cannot be triggered and is under locked state. In this way, when the user does not need to use the equipment, he only needs to turn the adjusting element <NUM> to the locked state, and the pneumatic switch <NUM> cannot be triggered, which greatly reduces the risk of the pneumatic switch <NUM> being triggered by mistake. When the stop block <NUM> rotates to the position where the first end <NUM> is not blocked, the sensing end <NUM> communicates with ambient air through the vent hole <NUM>, so that the air at the sensing end <NUM> can flow out smoothly, and drive the sensing end <NUM> to deform. At this time, the pneumatic switch <NUM> can be triggered, that is, it is under unlocked state. Through rotating the adjusting element <NUM>, the sensing end <NUM> and the vent hole <NUM> can be separated or communicated, so as to lock and unlock the pneumatic switch <NUM>, which is easy to operate.

In some embodiments, as shown in <FIG> and <FIG>, the rotating shaft <NUM> is misaligned with the sensing end <NUM>, and is eccentrically arranged with the stop block <NUM>. That is, the projection area of the rotating shaft <NUM> on the seal seat <NUM> does not overlap with the sensing end <NUM>, and the rotating shaft <NUM> does not pass through the center of the stop block <NUM>. In this way, the sensing end <NUM> and the stop block <NUM> are both eccentrically arranged relative to the rotating shaft <NUM>, so that the projection area of the stop block <NUM> completely cover the sensing end <NUM> to block the sensing end <NUM> when the rotating shaft <NUM> drives the stop block <NUM> to rotate. Correspondingly, the peripheral dimension of the stop block <NUM> is larger than that of the sensing end <NUM>. In practice, the stop block <NUM> may be in the shape of a sector, rectangle, square, ellipse or other structure.

Of course, the rotating shaft <NUM> can also be misaligned with the first end <NUM>, that is, the first end <NUM> and the stop block <NUM> are both eccentrically arranged relative to the rotating shaft <NUM>, and the first end <NUM> can be completely blocked by the stop block <NUM> to achieve the purpose of enclosing the sensing end <NUM>. Correspondingly, the peripheral dimension of the stop block <NUM> is larger than that of the first end <NUM>. Furthermore, the second end <NUM> is provided with a convex ring <NUM> protruding to the surface of the seal seat <NUM>. When the rotating shaft <NUM> drives the stop block <NUM> to block the first end <NUM>, the stop block <NUM> is elastically abutted against the convex ring <NUM> to increase the force between the stop block <NUM> and the first end <NUM>, improve the result of sealing, and thus improve the reliability of locking.

In some embodiments, the rotating shaft <NUM> comprises a rotating shaft body <NUM>, a knob <NUM> and a seal <NUM>. The rotating shaft body <NUM> passes through the rotation hole <NUM>, and one end is connected to the stop block <NUM>, and the other end is coaxially connected to the knob <NUM>. The rotating shaft body <NUM> is in a columnar structure. When the knob <NUM> rotates under force, the rotating shaft body <NUM> is driven to rotate around the central axis of the rotating shaft body <NUM>. The knob <NUM> is located outside the power supplying main body <NUM> and is attached to the periphery of the power supplying main body <NUM>. The seal <NUM> is fastened to one side of the knob <NUM> where the power supplying main body <NUM> is attached to, and is clamped among the power supplying main body <NUM>, the rotating shaft <NUM> and the knob <NUM> to seal the gap between the power supplying main body <NUM> and the rotating shaft <NUM>, realize the sealing of the mounting chamber <NUM>, and prevent the air in the mounting chamber <NUM> from flowing out of the gap, causing the pneumatic switch <NUM> to be triggered by mistake. In practice, the seal <NUM> can be a seal ring. A groove around the rotating shaft <NUM> is arranged on one side of the knob <NUM> which is connected to the rotating shaft body <NUM>, and the groove and the rotating shaft <NUM> enclose to form an annular groove matching the seal ring. The sealing ring is accommodated in the annular groove, and is elastically abutted against the knob <NUM>, the power supplying main body <NUM> and the rotating shaft body <NUM> respectively.
