Disclosed is an outlet device with hollow water curtain function, comprising a hollow housing (20) and a deflecting column (40) inserted in the housing (20), an annular passage (22) is formed between the housing (20) and the deflecting column (40), wherein the housing (20) further comprises a plurality of arc-shaped inlet slots (26), the arc inlet slots (26) are annularly arranged about the center of the annular passage (22), the internal port of the arc inlet slots is connected to the annular passage, water flows to the annular passage through the arc inlet slots (26) to from a hollow annular water curtain with centrifugal force. When the tangential centrifugal force of the water curtain orienting the opening angle of the housing is larger than the surface tension thereof, the water curtain breaks open to make the water flowing break open and diffuse as particles after keeping itself in a certain length, the diffused water forms a water type continuous in a certain range, the shower area is large, and the water particle feels good.

A rotating handle switching shower head, comprising a head part(100), a water diverter (200), a mandrel (300), and a handle (400); the head part (100) is provided with at least two water outlet functions and at least two water inlets (110); the water diverter (200) is fixedly connected to the head part (100), and has at least two groups of water diverting holes (230, 240) and at least two water diverting cavities (210), each group of water diverting holes (230, 240) corresponding to one water diverting cavity (210), and the water diverting cavities (210) extending into the head part (100), and one water diverting cavity (210) communicating with one water inlet (110); the mandrel (300) is pivotally connected to the water diverter (200) and provided with a water inlet channel (310), and rotates to drive the water inlet channel (310) to switch and lead to the water diverting holes (230, 240); the handle (400) rotates relative to the water diverter (200), and is fixed relative to the mandrel (300). Rotation of the handle (400) drives the mandrel (300) to rotate relative to the water diverter (200), thus realizing function switching, that is, a switching device is disposed on the handle (400). Therefore, the head part (100) of a shower head can be very thin; and the switching device consisting of the handle (400), the mandrel (300) and the water diverter (200) can fit with head parts (100) having different appearances, thus having good universality.

Disclosed is a showerhead with a detachable top cover. The showerhead comprises a main body unit (100) with a water outlet channel (700) able to communicate with the water supply, a rotatable water divider (200) installed and connected inside the main body unit (100), and a top cover (300). The water divider (200) is provided with an outer ring (210) and the outer ring (210) has an inner rotating face (213). The inner rotating face (213) is provided with an assembling/disassembling groove (214). The assembling/disassembling groove (214) comprises an in/out groove (211) running through to the outer end face of the outer ring (210) and a transverse groove (212) extending transversely from the inner port of the in/out groove (211). From an outer rotating face (301) of the top cover (300) protrude protruding seats (310). The protruding seats (310) and the assembling/disassembling groove (214) are adapted to one another such that the protruding seats (310) can enter the transverse groove (212) via the in/out groove (211) and such that the protruding seats (310) can enter the in/out groove (211) from the transverse groove (212) to disengage the assembling/disassembling groove (214). A snap-fitting structure (500) is provided between the outer ring (210) of the water divider (200) and the top cover (300) and is able to limit the relative rotation and is able to be assembled and disassembled. The water divider (200) and the top cover (300) are mounted together in a sealed manner and form multiple water outlet chambers (600) corresponding to multiple water outlet functions. The relative rotation of the water divider (200) and the main body unit (100) switches which of the multiple water outlet chambers (600) are in communication with the water inlet channel.

Le dispositif est notamment applicable à l'injection multipoint sur moteurs d'automobile. Il comporte au moins un injecteur (34) et un circuit électronique de commande (46) relié à des capteurs de paramètres de fonctionnement du moteur, notamment de la vitesse de ce dernier, et fournissant à l'injecteur des signaux périodiques de rapport cyclique fonction desdits paramètres, en synchronisme avec les mouvements du moteur lors du fonctionnement normal de ce dernier. Le circuit électronique de commande (46) est constitué de façon à appliquer à l'injecteur ou à chaque injecteur (34) des signaux asynchrones, de fréquence très supérieure à celle que donnerait la loi de fonctionnement normal, aussi longtemps que la vitesse du moteur n'atteint pas un seuil déterminé à partir du début du lancement.
摘要:
The invention relates to a method for manufacturing titanium oxide. In the method of the invention a sulfuric acid solution containing predominantly titanium ion together with one or more kinds of metal ions is brought into contact with an organic solvent. That solvent is one containing one or more species selected from oxygen-containing organic solvents, alkyl amines, and alkyl aryl amines and is used to extract the titanium ions in the form of a sulfuric acid complex from the sulfuric acid solution. Thereafter, the organic solvent containing the extracted titanium is brought into contact with water or a dilute aqueous sulfuric acid solution inversely to extract the titanium from the organic solvent into the water or the dilute sulfuric acid solution and to regenerate the organic solvent.
