Description

Go out sprinkler head

Technical field the utility model relates to the sprinkler head that goes out that is connected use with water tap or valve body outlet terminal.

Background technology is present, the water of various different structure forms, gas mixed foam spray water outlet shower nozzle all is to utilize negative-pressure siphon to make water, gas mixes formation foam spray, the structural member that produces negative-pressure siphon is cellular plate class or shell class part and inside and outside shell and the seal thereof that has the orifice plate characteristic with, filter screen is formed a negative pressure hybrid chamber, on the shell of hybrid chamber and the circumference between the inner casing, have for the gas passage that forms negative pressure, with be distributed on the shell side wall circumference three to four strip through holes communicate, gas enters from the water periphery, air flue is a straight, and water takes place directly to mix with gas; A plurality of holes on the part of orifice plate characteristic produce each self-forming negative pressure of action of turbulent flow respectively, and three to four the strip through holes of air on sidewall that inner casing is outer directly suck hybrid chamber, and its mixing also is disposable; Another kind of is that gas enters the form of circumference siphon to the periphery from the water outlet center, is to establish ring-type ventilation part at the center of hybrid chamber, utilizes three to four strips in its top or dentation groove that the gas branch is mixed with water to circumference; These two kinds of water, gas mixed form and negative-pressure gas passage all are single-stage and directly effect, because it is heterogeneous that this three to four strip through holes or dentation groove crack have determined negative-pressure gas to distribute on whole circumference, thereby cause when low pressure and high pressure turbulent flow siphon variation and water to overflow to gas circuit, the product adaptation range hydraulic pressure is restricted, for this class form that gas enters from the water periphery, water and housing contacts also shadow arrive water quality.

Utility model content the technical problems to be solved in the utility model is to avoid above-mentioned the deficiencies in the prior art part and proposes that a kind of siphonage power is evenly distributed and effective go out sprinkler head, and it is good to go out the foam water floral shape that sprinkler head comes out through this.

The utility model solve the technical problem can be by realizing by the following technical solutions:

Design, use a kind of sprinkler head that goes out, be installed in the water side of water tap, comprise shell, in this shell inner casing is housed, inner shell bottom is fixed with the filter screen group, has a plurality of air vents on the inner wall; Circular orifice is equipped with in the top of inner casing, has a plurality of holes on this orifice plate; In the described inner casing, and between described orifice plate and filter screen group, be provided with two-layer at least tubular inner bag, also have a plurality of air vents or backlash shape air channel crack on the wall of this two inner bag, all leave the gap between each adjacent both perpendicular wall of described two inner bags and inner casing and form multistage siphon chamber with compound wall structure, air vent on air vent on described two inner bags or air channel crack and the described inner casing staggers mutually at relative axial position and distance, and the air vent on the inner bag outside being positioned at is in the below of the air vent on the inner casing.

Described each tubular inner bag split setting or fuse.

Described each tubular inner bag is straight-through up and down ring-type, or the up big and down small tapering that has.

Described air vent or air channel crack are circular, square, oval or bar shaped, and each air vent on the same inner bag or edge, air channel crack inner bag circumferential wall separately evenly distribute.

Described orifice plate has at least two-layer, and each orifice plate is fixing in the enclosure in circumferential edge and black box combination back; Each orifice plate surrounds multistage hybrid chamber with black box.

Described each orifice plate is plane or lenticular, and the hole on the orifice plate is circular, square, oval or bar shaped.

Hole on described each orifice plate is evenly distributed or non-uniform Distribution, the hole on each orifice plate stagger mutually certain position and angle.

Described black box is the integral annular seal, has section on its inwall and is horizontal " U " type cannelure, and the periphery of described each orifice plate embeds in the described cannelure.

The black box that described black box is made up of at least two flat oil sealings or " 0 " RunddichtringO, the periphery of described each orifice plate are sandwiched in respectively between adjacent two flat oil sealings or " 0 " RunddichtringO.

Compare with prior art, the technique effect that the utility model goes out sprinkler head is: 1. adopt two-layer at least inner bag to form multistage siphon chamber with inner casing, the air vent that makes the siphon gas circuit simultaneously evenly distributes along the circumference of device separately, strengthen siphon effect, guarantee that siphonage power is evenly distributed, thereby make the spray form of water outlet good; 2. the air vent that is positioned at outmost inner bag is positioned at the air vent below of inner casing, and anti-effectively sealing between inner casing and the shell, has been avoided contacting of water and casing part through the air vent overflow, and assurance is to the water quality protection of the current of flowing through; 3. adopt multilayer orifice plate and black box to constitute multistage hybrid chamber, realize fully remedying and, make product function in big pressure limit reliable and stable the low pressure undermixing to the High-Pressure Water buffering of repeatedly damming; 4. because multistage mixing and multistage siphon, the ratio of sneaking into gas in the water significantly increases, and when reducing the water actual flow, allows the user feel that water yield is still bigger, conserve water resource significantly, and water-saving function is good.
