Fig. 5 is Fig. 1, Fig. 2, Fig. 3 and water spray view embodiment illustrated in fig. 4;

Fig. 6 is Fig. 1, Fig. 2, Fig. 3 and paper delivery view embodiment illustrated in fig. 4;

The C--C partial sectional view of Fig. 7 Fig. 1;

Fig. 8 is the electrical schematic diagram of delay switch.

Embodiment:

Referring to Fig. 1 and Fig. 3, shell is made up of casing 1 and case lid 2; The centre of casing 1 is provided with diaphragm plate 3, with two spaces about being separated in the casing 1; The left side of diaphragm plate 3 is provided with a L shaped mobile paper support 4, forms one between this L shaped mobile paper support 4 and the diaphragm plate 3 and holds paper space; Be provided with spring 5 between the behind of L shaped mobile paper support 4 and the casing 1, spring 5 promotes L shaped mobile paper support 4 and moves to diaphragm plate 3, and the feasible paper handkerchief that is placed on the L shaped mobile paper support 4 is close to down the drag head of palpus paper delivery rake 17; The riser of L shaped mobile paper support 4 is provided with a slotted hole, wears folder one L shaped supporting plate 16 by bolt 20 in the hole and constitutes described lifting platform.A kind of form that provides in being connected of described lifting platform version and L shaped mobile paper support 4 and spring 5, non-example of drive form, this all is that those of ordinary skills are easy to expect, key is the lifting of lifting platform energy, and L shaped mobile paper support 4 can be moved to the left and get final product.

Referring to Fig. 1, Fig. 4 and Fig. 7, paper feeding and squirt the left side that mechanism all is located at diaphragm plate 3.Loam cake 2 extends a groove downwards, and delay switch circuit 7, battery 8, gear reduction motor 9 and hypodontia multiple mounted cam 10 are established within it; Delay switch sensing chip 6 is located at the surface of loam cake 2.Described hypodontia multiple mounted cam 10 is composited by the cam and the fan-shaped hypodontia gear of disjunctor.Wherein, pinion 11 engagements of fan-shaped hypodontia gear parts and gear reduction motor 9 spindle noses; Cam portion is against the top of the plunger push rod 13 of plunger pumping device 12.When gear reduction motor 9 drive hypodontia multiple mounted cams 10 rotated counterclockwise, the cam portion actuation plunger pumping device 12 of hypodontia multiple mounted cam 10 will be taken out the water in the accumulator 14 outward, through shower nozzle 15 atomizing ejections.The atomized water of shower nozzle 15 ejections sees through diaphragm plate 3 and is sprayed at (referring to Fig. 5) on the paper handkerchief 18 equably.

Referring to Fig. 1 and Fig. 4, the side of the plunger push rod 13 of plunger pumping device 14 is extended one fall must paper delivery rake 17 to holding the paper frame, fall must paper delivery rake 17 drag head pass diaphragm plate 3 and put in and hold in the paper frame; Described fall must paper delivery rake 17 drag head be provided with down must 17A, must be towards the paper delivery direction.When the gear reduction motor passes through hypodontia multiple mounted cam 10 actuation plunger pumping devices 12 when shower nozzle 15 is outwards sprayed water through 9, fall must paper delivery rake 17 drag head pasting paper handkerchief 18 and moving down, this moment drag head moving direction along fall must direction, can not be with paper handkerchief 18 to move down; When the gear reduction motor after 9 delay workings finish, in plunger pumping device 12 under the effect of back-moving spring, the plunger push rod 13 of plug pumping device 12 returns, fall and to move on the paper rake 17, paper handkerchief 18 hooks must with moving on the drag head on the drag head, the paper handkerchief 18 after squirting stretches out exit slot set on the loam cake 2 19 (referring to Fig. 6).

Implement that the utility model will pay special attention to be back-moving springs in the plunger pumping device 12 elastic force as far as possible choosing can move down by actuation plunger push rods 13 with gear reduction motor 9 more greatly, can overcome resistance during 9 outages of gear reduction motor and slowly be returned as suitable.
