This application provides a water purifier, including a water circuit board, a faucet, an indicator light, and a detection element disposed within a water flow channel. The detection element includes a movable component; when the movable component is in a first state, it is stationary within the water flow channel, or it is in a first position; when the movable component is in a second state, it rotates within the water flow channel, or it is in a second position; and a sensing element disposed on the board. When water flows within the water flow channel, the movable component switches from the first state to the second state, and the sensing element transmits a sensing signal to activate the indicator light; when water stops flowing within the water flow channel, the movable component switches from the second state to the first state, and the indicator light turns off. This application detects the water flow within the water circuit board through the movement state and position of the movable component, and the indicator light on the faucet displays the water purifier's usage status to the user.

The utility model provides a manual point gum machine for display screen production relates to display screen production equipment technical field, include: point gum subassembly, point gum subassembly constitutes by point gum pipe, threaded rod and pump head, the pump head sliding connection is in the point gum pipe, threaded rod sets up at the top of pump head, the embedded installation of point gum pipe is equipped with visual glass, drive assembly constitutes by inside, outside drive disc, the layout is exquisite, the effect is remarkable, the first tooth groove of inside drive disc outside and the inside ring of outside drive disc mesh, realizes the collaborative operation of inside and outside disc, power transmission is efficient and stable, the second tooth groove of outside drive disc outside and the drive gear on fixed link mesh, supports through fixed link, drive gear can accurate drive outside drive disc rotation, this structure makes the drive flexible controllable of point gum pipe, can accurate regulation rotating speed and torque according to the operation demand, guarantees the smooth, accurate of point gum operation, has greatly promoted the working performance and product quality of point gum equipment.

This invention relates to a novel switch, comprising: a switch mechanism assembly including a switch base and a moving contact, a stationary contact, and a pressure assembly disposed within the switch base, wherein the pressure assembly can cause the moving contact to contact or separate from the stationary contact under external force; characterized in that it includes: a knob rotatably disposed above the switch base; a dial, the upper surface of which has a rotating shaft fixedly connected to the knob, and the lower surface of which has a pressure block that abuts against the pressure assembly; during the rotation of the knob, the knob can drive the dial to rotate around the axis of the rotating shaft, thereby causing the pressure block on the dial to abut against the pressure assembly, thus causing the moving contact to contact or separate from the stationary contact. This rocker switch can be turned on and off simply by rotating the knob, and the rotation of the knob allows for precise force application to accurately control the switch's on / off state, thereby improving the switch's lifespan.

The present application relates to a kind of precision guiding nest-preventing device and nest-preventing method integrated in sewing machine needle plate, the device is provided with fixed knife and movable knife on the lower surface of sewing machine large needle plate, the movable knife includes hooking part, dividing part, wire container groove and wire hole, cooperates with presser foot, blowing and suction pipe and connecting rod type driving mechanism, through the timing design of "stitching thread - guiding presser - stabilizing thread loop - cutting cleaning - resetting", realizes the precise guidance of thread end, cutting and cleaning.The device can reuse the built-in power of sewing machine, has compact structure and strong adaptability, can completely avoid the winding of starting thread, improve the quality and operation continuity of sewing product, and is suitable for all kinds of sewing machines such as lockstitch machine and pattern machine.

The utility model relates to the technical field of rehabilitation instruments, and discloses a limb rehabilitation training device with a variable stiffness function, which comprises a casing, a support frame is fixedly mounted in the casing, two pairs of bearing seats are fixedly mounted in the support frame, and rotating shafts are rotatably mounted in the bearing seats; a guide shaft support is rotationally mounted in the center of the supporting frame through a rotating seat, one end of a guide shaft is fixedly mounted in the guide shaft support, and the guide shaft is sleeved with a sliding block; the ends, away from each other, of the two rotating shafts on the upper side are each rotationally provided with one end of a swing rod, the other ends of the swing rods are fixedly provided with the same cross rod, the sliding blocks are provided with elastic pieces, and the supporting frame is provided with an adjusting assembly used for lifting the sliding blocks. The limb training rigidity of a patient can be changed, the structure is simple, work is stable, and therefore on the premise that man-machine interaction safety is guaranteed, the control accuracy of the training device can be kept accurate for a long time, and the device is more reliable in overall operation, longer in service life and better in durability.
