For realizing above-mentioned purpose; The technical scheme of the utility model is: a kind of flexible concealed sprinkler; Comprise nozzle body, said nozzle body comprises the shower nozzle seat of honour, gear opener and the splash box that connects successively, and said gear opener is provided with thalposis memory metal body; Said splash box middle part is provided with through hole; Thalposis memory metal body stretches out the extraneous temperature of splash box induction through through hole, and said shower nozzle seat of honour inner chamber is embedded with first magnet, and said gear opener top is provided with polarity second magnet opposite with first magnet.
Further, the intracavity bottom at the said shower nozzle seat of honour is provided with logical boss in, and the boss periphery is provided with annular groove, and first magnet is enclosed within on the groove, and the boss below is provided with the threaded sleeve that is connected with the gear opener.
Further, said gear opener mainly comprises tooth axle, axle sleeve, gear and driving sleeve, and said tooth axle top is round flap structure, and the bottom is band flute profile axle core, and the flap lower surface is provided with sealing gasket, and second magnet is enclosed within the upper surface of flap; There is screw thread on said axle sleeve top and is fixedly connected with the threaded sleeve at the shower nozzle seat of honour, and the body of axle sleeve cylinder type is provided with the many to little tooth axle of symmetry, correspondingly on the little tooth axle is equipped with manyly to gear, and its profile of tooth is identical with little tooth axle; Said driving sleeve is a cylindrical structure, and cylinder inner wall is provided with the gear teeth, and its profile of tooth is identical with little tooth axle; Said thalposis memory metal body is arranged on the middle part of driving sleeve, and the bottom of driving sleeve is provided with screw thread and is fixedly connected with splash box.
Further, said little tooth axle is 3 pairs, and correspondingly gear is 3 pairs.
Further, said thalposis memory metal body is an elastic construction.
Further, said nozzle body places cylinder cover, and is embedded in the body of wall in the lump.
Compared with prior art, the utlity model has following beneficial effect:
The utility model utilizes the metamorphosis invertibity of attractive interaction and the temperature-sensitive memory metal of two magnets to control the keying of shower nozzle, and when servo condition, shower nozzle is in retracted mode; Be hidden in the body of wall, and when needs work, shower nozzle is in the state of stretching out; And carry out fire extinguishing water, and avoid the mistake of shower nozzle to open, the utility model can be recycled; Avoid the waste of resource, and do not influence indoor attractive in appearance.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is carried out detailed description.
Extremely shown in Figure 4 like Fig. 1; The utility model discloses a kind of flexible concealed sprinkler; It comprises nozzle body, and said nozzle body comprises the shower nozzle seat of honour 1, gear opener 4 and the splash box 6 that connects successively, and gear opener 4 is provided with thalposis memory metal body 5; Splash box 6 middle parts are provided with through hole; Thalposis memory metal body 5 stretches out the extraneous temperature of splash box 6 induction through through hole, and the shower nozzle seat of honour 1 inner chamber is embedded with first magnet 2, and gear opener 4 tops are provided with polarity second magnet 45 opposite with first magnet 2.Gear opener 4 is the counteragent opener.
In the present embodiment, nozzle body places cylinder cover 10, and is embedded in the lump in the body of wall 11; Among the figure, shower nozzle seat of honour 1d intracavity bottom is provided with logical boss 11 in, and boss 11 peripheries are provided with annular groove 12; Be with first magnet 2 on the annular groove 12; Boss 11 belows are provided with the threaded sleeve 13 that is connected with gear opener 4, and like Fig. 4, threaded sleeve 13 is fixing with boss 11 with three reinforcements 14; Gear opener 4 mainly comprises tooth axle 41, axle sleeve 42, gear 43, driving sleeve 44, and the top of tooth axle 41 is round flap structure, and the bottom is band flute profile axle core, and the flap lower surface overlaps with sealing gasket 3, and upper surface overlaps with second magnet 45; The top of axle sleeve 42 is processed with screw thread and is fixedly connected with the threaded sleeve 13 at the shower nozzle seat of honour 1, and the body of its cylinder type is provided with the little tooth axle of 3 couple of symmetry, and 3 pairs of gears 43 are housed on the little tooth axle, and its profile of tooth is identical with little tooth axle; Driving sleeve 44 main bodys are cylindrical structure; Cylinder inner wall is provided with the gear teeth; Its profile of tooth is identical with little tooth axle; Thalposis memory metal body 5 is provided with the middle part of driving sleeve 44, the elastic construction of thalposis memory metal body 5 type of being spring forms, and the bottom of driving sleeve 44 is provided with screw thread and is fixedly connected with splash box 6; Splash box 6 stretches out splash box 6 through the through hole at middle part, thus the extraneous variations in temperature of induction.
The operation principle of the utility model is:
Like Fig. 2; When system is in servo condition; Thalposis memory metal body 5 is in contraction state, and first magnet 2 at the shower nozzle seat of honour 1 is the heteropole device with second magnet 45 on the tooth axle 41, and the magnetic force between them shows as attraction; The sealing gasket 3 that is with on the tooth axle 41 thus receives on the boss 11 that downward absorption affinity is pressed in the shower nozzle seat of honour 1, and this moment, shower nozzle was in closed condition.
Like Fig. 3, when the condition of a fire, and when reaching the temperature-sensitive critical point of thalposis memory metal body 5; Memory metal generation metal phase change and distortion directly change heat energy into mechanical energy and constantly extend, because thalposis memory metal body 5 is mounted between axle sleeve 42 and the driving sleeve 44; And axle sleeve 42 is to be fixed on the shower nozzle seat of honour 1, so the elongation of thalposis memory metal body 5 can only show as downward promotion driving sleeve 44, when metal phase change power during greater than the magnet attraction; Driving sleeve 44 is down pushed with splash box 6 in the lump; Outside body of wall 11, at this moment, the driven gear 43 that moves downward of driving sleeve 44 rotates; The suction that the rotation of left and right tooth wheels all will make the tooth axle overcome magnetic force up moves, and at this moment the system water source is through the through hole edge direction directive splash box 6 straight down of shower nozzle bottom; When temperature drops to room temperature, 5 withdrawals of thalposis memory metal body, downward magnet suction played a leading role and drove driving sleeve 44 through gear 43 and up moves this moment, and tooth axle 41 is closed and is pressed down, and splash box 6 resets, and arrow is the direction at water source among Fig. 3.
