Abstract: A switch device includes a male assembly, and a female assembly. The male assembly includes a first fixing seat, a first operation socket, a first locking seat, and a retractable rod. The female assembly includes a second fixing seat, a second operation socket, and a second locking seat. Thus, the male assembly can be detached from the female assembly rapidly, thereby facilitating the user operating the switch device to open the door of the refrigerator. In addition, the user only needs to press the door of the refrigerator so as to open the door of the refrigerator easily and conveniently, thereby facilitating the user opening the door of the refrigerator.

Abstract: A timing lock device for a faucet includes a valve seat, a top cover, a locking washer, a relief rod, a locking valve shaft, and a compression spring. In use, the relief rod may be used to release the water pressure in the pressure storage chamber of the top cover. Then, the locking washer may be moved upward by the locking valve shaft, so that the water may flow outward. When not in use, the water may flow through the return through hole of the top cover into the pressure storage chamber. Thus, the water flow may be stopped automatically by the restoring force of the compression spring and the water pressure in the pressure storage chamber, thereby saving the manual work, and thereby achieving an excellent leakproof effect.

Abstract: The present invention relates to an instantaneous multistage and water-saving valve wherein a swinging rod is used to trigger the pushing element and the value, and the number of the sloping teeth on the engaging hook block can provide multiple stage of water flow rate so as to provide a rapid and convenient operation in supplying water. When the swinging rod is triggered so as to turn off water supply, the upper half of the pushing rod is urged and this will urge the pushing element to become slanting, and the end terminal edge will urge the blocking section of the cavity chamber. Thus, the valve is moved forward to achieve the turning on and turning off action in a multiple stage of operation.

Abstract: The present invention discloses an improved structure of a fixation and anti-leakage socket joint, comprising a soft tube, a blocking ring in the inner tube, a fixation ring on the outer tube and two fitting rings around the both ends of the tube; a blocking ring in the inner socket; a soft tube completely wraps the adjustable pipes; the thread on the socket; the elastic grips extended from the socket; two caps on both sides of the socket. When the caps are fastened, the elastic grips are squeezed inwards to compress the soft tube and therefore fix the pipes. Such socket joint provides a fixation and anti-leakage device for the users to handle the adjustable pipes more easily and safely.

Abstract: A water spraying gun includes a gun housing with a hollow handle portion and a spout portion, a spring-loaded valve to control fluid flow between the handle portion and the spout portion, an operating lever coupled to the valve, and a positioning unit that includes a slide member with a vertical guiding face which is formed with a V-shaped first guiding channel, a V-shaped second guiding channel above the first guiding channel, and a V-shaped third guiding channel above the second guiding channel. Each of the guiding channels has a left section which inclines upwardly and leftward, and a right section which inclines upwardly and rightward. The guiding face is further formed with a vertical right guiding groove on a right side of the guiding channels and communicated with upper ends of the right sections of the guiding channels, and a vertical left guiding groove on a left side of the guiding channels and communicated with upper ends of the left sections of the guiding channels.

Abstract: An electrically operated oscillatory toothbrush comprises generally a housing, a motor in the housing, an actuator, an oscillator and a sleeve member sequentially secured to the top of the housing and protected by a cap member, and a toothbrush secured into the upper portion of the cap member. The character of this disclosure is that the sleeve member has a transverse slot in cooperation with a recoil spring connected between the oscillator and the sleeve member so as to limit the oscillator to swing within a certain range of angle in order that the toothbrush oscillates with intermittent elastic vibrations to an extent to perfectly clean a user's teeth.

Abstract: A pneumatic controlled infusion bag comprises a double-layer infusion bag, a space defined between the layers for receiving pneumatic pressure therein to gradually squeeze the medicament inside the bag delivering into the vessel of a patient. A pneumatic fluid control assembly controllably supplies the pneumatic pressure into the infusion bag. The assembly comprises an air inlet connected to a pneumatic source, an outlet connected to the bag via a hose, a first and a second piston disposed inside the assembly for respectively controlling the open/close and the proper amount of the pneumatic pressure. A pressure release valve inside the infusion bag can automatically release the excessive pneumatic pressure out of the bag. This disclosure overcomes the resistance of the blood pressure and needs no longer to form a potential difference between the infusion bag and the human body.

Abstract: A structure of a rehabilitating device for automatically closing a movable object comprises a tubular body having a first and a second chamber therein, a cylinder member having a cock mechanism at the inward end axially disposed into the tubular body, a sleeve member incorporated with a pair of steel balls in opposite peripheries sleeved onto the cylinder member and biased at two end by a pair of recoil springs and an air valve fastened to the open end of the tubular body abutting the first chamber. When the cylinder member is extracted outward, the spring is contracted and the air pressure is induced into the first chamber for a slow rehabilitation of the cylinder member. A further extracting the cylinder member leads the sleeve member entered into the second chamber to perform a random positioning of the cylinder member therein.
