Description
Technical field
The utility model relates to a kind of shower nozzle, particularly relates to a kind of shower nozzle can changed in spraying and direct current two states.
Background technology
At a lot of application scenarios, often need to utilize the mist formed by tiny liquid pearl.Such as utilize water smoke to put out a fire, through checking, the efficiency of this fire-fighting mode is higher, also can save water source simultaneously.In addition, also have much similar application scenarios, such as spraying insecticide to crops, is trees dedusting, and vehicle cleaning etc.
In above-mentioned application scenarios, fine mist spray head is usually utilized to utilize pressure that water or other liquid rotatings are become mist.And existing fine mist spray head defect is: only can regulate spray fog-supplying amount number, can not current be sprayed.This defect often causes puzzlement in above-mentioned application scenarios.Also for fire extinguishing, suddenly run into when needing current (when such as needing to spray a large amount of water to burning things which may cause a fire disaster far away) when utilizing fine mist spray head to put out a fire, just need to change shower nozzle, or call other water pipe and deal with, this can lose valuable time and spray meeting.
For solving the problem, a kind of waterfog head with auto-conversion function as disclosed in the patent No. Chinese utility model patent " a kind of waterfog head with auto-conversion function " that is ZL201420347670.6 (notification number is CN203899782U), it includes shower nozzle shell and nozzle boss, nozzle boss is inserted in rear formation between nozzle boss and shower nozzle shell in this installation cavity and changes chamber, nozzle boss offers concentrated direct current runner spaced apart up and down and diffusion spraying runner, direct current runner is concentrated to be communicated with conversion chamber with the inner of diffusion spraying runner, steel ball is provided with in conversion chamber, under waterfog head forward laying state, it is inner that steel ball is blocked in the runner being positioned at below in concentrated direct current runner and diffusion spraying runner, when under the reverse laying state of upset waterfog head, another runner that steel ball is blocked in concentrated direct current runner and diffusion spraying runner is under gravity inner.After adopting said structure, originally novel have multi-functional automatic conversion, and structure is simple, and good airproof performance, easy for operation, it is convenient to safeguard, can switch the feature of jet mode according to field demand in time fast.But on nozzle boss, offer direct current runner and diffusion spraying runner, and need to be provided with steel ball in conversion chamber, its shortcoming is structure relative complex, and liquid repeatedly changes flow direction in sprayer body, add internal flow loss and energy dissipation, and its difficulty of processing is larger.
Therefore, need to be improved further waterfog head.
Utility model content
Technical problem to be solved in the utility model provides a kind of simple realization to spray the shower nozzle changed between water smoke and the two states of current for above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above adopted technical scheme: this shower nozzle, comprise nozzle and be inserted into the inner core in described nozzle, between the madial wall of described inner core and described nozzle, there is gap, it is characterized in that, also include the nozzle cage that sealing shroud is located at described nozzle-end lateral wall, the end of described nozzle cage is provided with liquid outlet, wherein, the madial wall of described nozzle cage forms the first groove and the second groove that are oppositely arranged, and the opening bore of described first groove and the second groove diminishes gradually, described nozzle-end lateral wall then forms the first convex tendon and the second convex tendon that are tight against mutually with described first groove and the second groove at correspondence position, when described nozzle cage rotates along described nozzle-end lateral wall, described first convex tendon and the second convex tendon move towards synchronization-sliding along the opening bore of described first convex tendon and the second convex tendon respectively, thus make described nozzle cage occur progressively to change at the axial distance of described nozzle-end.
Further, described nozzle-end lateral wall forms the annular groove for sealing ring location.By coordinating of annular groove and sealing ring, the nozzle of shower nozzle can be tightly connected with nozzle cage.
Further, the tail end of described inner core has radial protuberance, and the madial wall of described radial protuberance and described nozzle offsets, and the lateral wall footpath convex of described inner core has first locating piece and the second locating piece that can offset with the madial wall of described nozzle.Closely offseted by the madial wall of inner core and nozzle, can be formed between inner core and the madial wall of nozzle and form narrow and small fluid passage.
As preferably, the length of described first groove and the second groove accounts for 1/4 ~ 1/3 of the madial wall girth of described nozzle cage respectively.When the length of the first groove and the second groove accounts for 1/4 of the madial wall girth of nozzle cage respectively, nozzle cage roughly rotates 100 ° along nozzle-end lateral wall, when the length of the first groove and the second groove accounts for 1/3 of the madial wall girth of nozzle cage respectively, nozzle cage roughly rotates 90 ° along nozzle-end lateral wall.
Further, described nozzle cage occurs progressively to change at the axial distance of described nozzle-end in the scope between 0 ~ 0.3mm.At nozzle cage when the axial distance of nozzle-end is 0, nozzle and nozzle-end fit tightly, what at this moment nozzle cage liquid outlet sprayed is exactly spray water, and nozzle cage is when the axial distance of nozzle-end is greater than 0 and is less than 0.3mm, what at this moment nozzle cage liquid outlet sprayed is exactly linearity water, therefore, rotary nozzle cover is only needed can to realize the conversion of linearity and vaporific two states.
Compared with prior art, the utility model has the advantage of that operation is fairly simple, only need to be rotated along the rotation of nozzle-end lateral wall by nozzle cage to regulate the relative position of nozzle cage liquid outlet and interior core head through hole, utilize the madial wall of nozzle cage to form to be oppositely arranged and the first groove of diminishing gradually of opening bore and the second groove, match with the first convex tendon of nozzle-end lateral wall and the second convex tendon, can shift near and away between change, can change between water jet and atomized water spray two states easily, to tackle different application demands.
