Description

Water spraying mechanism

[technical field]

The utility model is about a kind of water spraying mechanism, especially relates to a kind of water spraying mechanism of unidirectional water outlet of the child's of being used for articles for use.

[background technology]

Child's articles for use and toy series still lack functions such as watering, water spray at present, the lack of diversity interest, and the general structure of more existing water spraying mechanisms is simple and crude, damage easily, and not only delivery port water outlet when pushing water spray, water inlet also have the water ejection simultaneously, cause the undercapacity of spraying water, injection flow rate is not enough, flowing backwards appears in liquid in the water pump, and the structure ten minutes is science not, lacks flexibility, interest, pressing mechanism is impaired easily, is difficult to be applicable to child's articles for use and toy utensil.

Therefore, prior art is improved, a kind of flexible, compact conformation is provided, the water spraying mechanism of unidirectional water outlet is real to be necessary.

[summary of the invention]

The purpose of this utility model is to provide a kind of flexible, compact conformation, the water spraying mechanism of unidirectional water outlet.

To achieve these goals, the utility model adopts following technical scheme:

A kind of water spraying mechanism is provided, it comprises depression bar and water pump body, is provided with spring in this water pump body, can relatively move between this depression bar and the water pump body, this water pump body further comprises flowing water Valve, inlet valve, and place flowing water Valve and inlet valve place go out water piston and the water inlet piston.

This goes out water piston and the water inlet piston can be a T shape plunger, also can be other shape.In water inlet during state, water feeding pressure makes into that the water piston goes out water piston and stops up flowing water Valve away from inlet valve, and this inlet valve is in open mode, and flowing water Valve is in closed state.Press to water pump body at depression bar, be in water state, water outlet hydraulic pressure makes into that the water piston goes out water piston away from flowing water Valve away from inlet valve, and this inlet valve is in closed state, and flowing water Valve is in open mode, there is no aqueous reflux during water spray.

Water pump body further comprises loam cake and the lower cover that is combined into water receptacle, and be positioned at spring one end can be by the piston of pressing spring, this flowing water Valve and inlet valve are arranged at lower cover.This depression bar forces in piston, thereby the water in the water receptacle is pushed away from flowing water Valve.

Be connected with water out adapter and water supply connector at flowing water Valve and inlet valve place.This water out adapter is connected with outlet pipe and the water outlet gland that is socketed on the outlet pipe, and this water outlet pressure covers and is provided with delivery port, and this delivery port is less than the bore of outlet pipe, so that current speed up when delivery port, forms and sprays.This water supply connector is connected with water inlet pipe.

Compared with prior art, button of the present utility model has following beneficial effect:

Water spraying mechanism of the present utility model advancing/and water outlet place is provided with unidirectional through-flow piston, can realize unidirectional water outlet, its flexible function, compact conformation, it is effective to spray water.

[specific embodiment]

As depicted in figs. 1 and 2, a kind of water spraying mechanism, it comprises depression bar 2 and water pump body 3, be provided with spring 33 in this water pump body 3, can relatively move between this depression bar 2 and the water pump body 3, this water pump body 3 further comprises flowing water Valve 321, inlet valve 322, and place flowing water Valve 321 and inlet valve 322 places go out water piston 11 and water inlet piston 12.

This goes out water piston 11 and water inlet piston 12 is T shape piston, in water inlet during state, water feeding pressure makes into that water piston 12 goes out water piston 11 and stops up flowing water Valves 321 away from inlet valve 322, this inlet valve 322 is in open mode, and flowing water Valve 321 is in closed state.Press to water pump body 3 at depression bar 2, be in water state, water outlet hydraulic pressure is used water piston 11 away from flowing water Valve 321, water inlet piston 12 stops up inlet valve 322, this inlet valve 322 is in closed state, and flowing water Valve 321 is in open mode, there is no aqueous reflux during water spray.

Water pump body 3 further comprises loam cake 31 and the lower cover 32 that is combined into water receptacle, and be positioned at spring 33 1 ends can be by the piston 34 of pressing spring 33, this flowing water Valve 321 and inlet valve 322 are arranged at lower cover 32.This depression bar 2 forces in piston 34, thereby the water in the water receptacle is pushed away from flowing water Valve 321.

Be connected with water out adapter 13 and water supply connector 14 at flowing water Valve 321 and inlet valve 322 places.This water out adapter 13 is connected with outlet pipe 15 and the water outlet gland 17 that is socketed on the outlet pipe 15, and this water outlet gland 17 is provided with delivery port 171, and this delivery port 171 is less than the bore of outlet pipe 15, so that current when delivery port 171, speed up, forms and sprays.This water supply connector 14 is connected with water inlet pipe 16.

In conjunction with reference to figure 3-Fig. 6, when pressing moulded rod 2, depression bar 2 promotes the spring 33 in the piston 34 pushing water pump bodies 3, spring 33 savings potential energy, water pump body 3 internal volumes dwindle, water outlet this moment hydraulic pressure is used water piston 11 away from flowing water Valve 321, water inlet piston 12 stops up inlet valve 322, this inlet valve 322 is in closed state, flowing water Valve 321 is in open mode, water in the water pump body 3 is via flowing water Valve 321, water out adapter 13, outlet pipe 15, and the delivery port 171 by water outlet gland 17 sprays again.

When depression bar 2 is depressed into spring 33 the most in short-term, spring 33 potential energy maximums, water pump body 3 internal volume minimums, water amount minimum, water spray is in done state.

When discharging depression bar 2, spring 33 discharges potential energy, promoting depression bar 2 and piston 34 resets, water pump body 3 internal volumes increase, make inlet valve 322 places water pressure pushing water inlet piston 12 away from inlet valve 322, pressure differential promotes out water piston 11 and stops up flowing water Valve 321, and this inlet valve 322 is in open mode, flowing water Valve 321 is in closed state, and water enters in the water pump body 3 via water inlet pipe 16, inlet valve 322.

When spring 33 potential energy discharge fully, depression bar 2 and piston 34 reset fully, water pump body 3 internal volume maximums, and the water amount is maximum, and water inlet is in done state.

So, realize the water spray and the water inlet function of this water spraying mechanism, the time there is no at water spray and the aqueous reflux phenomenon occurs.
