Abstract

The utility model relates to the field of a water-saving multi-purpose water tap, particularly the invention of a water-tap nozzle. A water outlet pipe of an existing water tap is divided into a transverse pipe and a stand pipe, wherein, the combining place of the transverse pipe and the stand pipe is provided with two side flow openings, the upper part of the stand pipe is a mixed flow pipe, the middle part of the stand pipe is a spiral pipe, and the inner part of the stand pipe is provided with two symmetrical spiral grooves which spirally descend along the stand pipe wall; in addition, the spiral surfaces of the spiral grooves decrease gradually, and the lower part of the stand pipe is a guiding pipe. The utility model can generate water stream which is similar to sprinkling or a column shape and is difficult to splash, and has the functions of one water-tap nozzle with two kinds of water stream. The utility model has the advantages of water saving positive effect, few parts, small volume, and economical and practical effects, and is suitable for the popularization and application of tap water users.

Description

The multipurpose water-saving water faucet mouth

The utility model relates to multipurpose water-saving water tap field, particularly about the invention of water faucet mouth.

Existing various water tap by retrieval, most of all is empty at valve chamber to nearly this section of water outlet is general, the water of outflow is column, what have splashes at hydraulic pressure Gao Shiyi, wastes bigger; What have has installed screens additional at the water outlet place, splashproof intubator, shunting core etc., and the water of outflow is the spray shape, and current are mellow and full soft, but should not use in some occasion, and above-mentioned two kinds of current can only be selected a kind of use.Chinese patent 92234597.X discloses the water conserving tap of a kind of column, the combination of spray shape current, though can choose at random current, complex structure, part is many, and volume is big, and high being not suitable for of cost promoted the use of.

The purpose of this utility model is in order to solve the deficiencies in the prior art, provide a kind of economical and practical, volume is little, cost is low, and can provide two kinds of different current, the multipurpose water-saving water faucet mouth.

The utility model is achieved in that water tap valve chamber to this section of water outlet outlet pipe is divided into two sections of transverse tube and vertical tubes, transverse tube is a deltiod, vertical tube is round, vertical tube is vertical with horizontal plane, vertical tube is divided into mixed flow tube again, volute, three sections of guide pipes, two effluent mouths are arranged in both sides on the vertical tube wall of transverse tube and vertical tube junction, two effluent mouths are at the sectional area of the switch-side sectional area greater than the mixed flow tube side, respectively there is a certain angle the bottom surface of each effluent mouth with leaning on median surface, its angle is at 20 °-40 °, with 30 ° of angles is the best, and two long-pending summations in effluent mouth mixed flow tube lateral section equal the sectional area of switch water outlet.The 1-2 that the interior sectional area of mixed flow tube is a sectional area in the transverse tube is the best with 1.5 times doubly.At the top of vertical tube one screw lid is arranged, on the top of vertical tube is mixed flow tube, the middle part is a volute, 180 ° of angles and symmetrical along vertical tube wall spiral spiral chute (spiral chute in the volute can be one or more) that descend, that helicoid reduces gradually each other, two tops are arranged in volute, there is a chimb outside of helicoid on the spiral chute, all on a horizontal plane, the bottom of vertical tube is a guide pipe for two spiral fluted top and terminal.Tap water is at ground core gravitation and the centrifugal force that descends and to be produced by the spiral chute spiral when middle small water flow, just produce rotary water current along the vertical tube wall, under the effect of guide pipe, make tap water,, produced the effect of spray along the cascade of mouth of pipe generation waterfall shape by water outlet, when big water quantity, if hydraulic pressure is higher, tap water by switch, effluent mouth continuous decompression and vertical tube in gradually stretch structure, just produce column current rotation, that be difficult for splashing.

Owing to adopted such scheme, the utility model has obtained two kinds of different current, and has taked the step-down measure, also can not produce when making hydraulic pressure high and splash, reached the purpose of water saving, it has economical and practical, not fragile, characteristics such as volume is little, stable performance.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a plan view of the present utility model.

Fig. 2 is left view of the present utility model (a C-C section).

Fig. 3 is plan view of the present utility model (an A-A section).

Fig. 4 is a transverse tube bending upwards type structural drawing of the present utility model

Among the figure: chimb 5 effluent mouths 6 screw lids 7 sealing gaskets 8 mixed flow tubes 9 volutes 10 guide pipes on 1 transverse tube, 2 vertical tubes, 3 spiral chutes, 4 helicoids

On the vertical tube wall of transverse tube (1) and vertical tube (2) junction, two effluent mouths (5) are arranged among the figure, at the bottom surface of two effluent mouths (5) and the angle that respectively has by median surface about 30 °, the effluent mouth is at the sectional area of switch-side sectional area such as Fig. 2, Fig. 3 greater than the mixed flow tube side, and it has two effects: 1. it has guiding and improves the effect of lift that 2. it has hypotensive effect again when hydraulic pressure is high.One screw lid (6) and sealing gasket (7) are arranged on the top of vertical tube (2), the top of vertical tube is mixed flow tube (8), the middle part is volute (9), two tops are arranged in the inside of volute (9), and 180 ° and symmetry descend along vertical tube wall spiral each other, the spiral chute (3) that its helicoid width reduces gradually is as Fig. 1, Fig. 3, the top of spiral chute (3) and terminal (no matter several groove) are all on a plane, there is a chimb (4) the helicoid outer end of spiral chute (3) as Fig. 1, Fig. 3, in the bottom of volute is guide pipe (10), by above measure, in, make the water yield equilibrium during the little water yield by each spiral chute (3), the loss of current when having reduced the little water yield, also can around water outlet, form waterfall shape cascade preferably even the water yield is little like this, can give the big sensation of the water yield so intuitively, can play certain good effect to using water wisely, when big water quantity, continuous decompression by running water switch and effluent mouth (5), and volute (9), guide pipe (10) is gradually stretched the structure of shape, can play a positive role to slowing down column current and splashproof.Inside and outside footpath, each position of vertical tube is identical as Fig. 1, and it can be installed on the water tap of (being suitable for this water faucet mouth) different size, and the transverse tube of this model utility (1) can adopt bending upwards type structure such as Fig. 4 of flat-square-shaped.
