Background technology

California energy commission, by a newest water saving bill (California restrict water supply new rule), is hereafter bought to resell for bathhouse article The water faucet equipment sold, it is required for reducing water consumption, it is contemplated that 10,300,000,000 gallons of use water, California energy commission can be saved within the 1st year (California Energy Commission) requires to include peddling for tap, it is necessary to reduces water consumption.Such as： (1), flow velocity of resident family's bathroom taps no more than 1.2 gallons per minute, regulation before this is 2.2 gallons.(2) it is, public Bathroom taps water consumption is then no more than 0.5 gallon per minute.(3), kitchen faucet streamflow is necessarily less than per minute 1.8 gallons, but can have speedup selection, it can increase to 2.2 gallons per minute when toward water receiving in pot.And the one of prior art Kind saves wetting system (Aerator), and as shown in figure 11, its tap 40 is provided with a wave device 50, the wave inception with an outlet pipe 41 lock Device 50 is to be sequentially equiped with a wave inception part 52, a water diversion disk 53 and a flow regulator pieces 54, the wave device 40 and water outlet in a shell 51 Leak-proof gasket 55 is folded between pipe 41, current is sequentially flowed through the throttle orifice 541 of flow regulator pieces 54, water diversion disk 53 and wave inception part 52, and using the reduced bore limitation water-carrying capacity of throttle orifice 541, and then have the water-saving and current wave inception effect of tap 40 concurrently, But above-mentioned prior art construction to be observed in detail to be not difficult to realize that it also has a little weak point, the flow regulator pieces 54 are rigid plate body, Therefore the aperture of its throttle orifice 541 is fixed, to prevent the too small situation about blocking in the aperture of throttle orifice 541, the prior art Throttle orifice 541 all design and restricted water supply the limited water yield of new rule more than California, therefore when current hydraulic pressure is low, the throttle orifice The 541 water column flow velocity deficiencies formed so that rely on flow velocity and attract the suction of air mixing to reduce (making great efforts law in vain), make current It can not effectively be cleaned, cause the extension of scavenging period will waste water all the better, when current increase, due to the flow regulator pieces 54 Throttle orifice 541 aperture it is constant, water yield regulation can not be carried out according to hydraulic pressure size, therefore increased hydraulic pressure will make to flow through Water increase, make the reduction of water-saving effect, and California can not be met and restricted water supply new rule regulation, if in order to meet regulation, will be whole The pipeline of tap is changed, it appears is not met economic benefit, the replacing wish of user can be also greatly reduced so that California New rule of restricting water supply are difficult to implement, and such as United States Patent (USP) case US20130032231, the problem of there is also that can not adjust its water yield, make Its water-saving is ineffective.

On the other hand, the shower head structure of the prior art, as shown in figure 12, the shower nozzle 60 are mainly connected with a body 61 A Water outlet 62 is connect, and forms the leak preventing effect of junction between the body 61 and Water outlet 62 with a packing ring 63, and the water outlet Offered at first 62 multiple water sprayering holes 621 be used for produce watering shape outlet effect, and the shower nozzle 60 of the prior art is designed as There is water-saving effect, it will flow regulator pieces 64 are added in the junction of body 61 and Water outlet 62, due to the rigid flow regulator pieces 64 aperture is constant, water yield regulation can not be carried out according to hydraulic pressure size, therefore the water that increased hydraulic pressure will make to flow through increases Add, make the reduction of water-saving effect, to improve water-saving effect, whole Water outlet 62 must be changed, it appears economic benefit is not met, Also the replacing wish of user can be greatly reduced so that California, which restricts water supply newly to advise, to be difficult to implement, therefore, if packing ring 63 only can be replaced just It can make shower nozzle 60 that there is water-saving effect, can effectively reduce replacement cost.

In view of this, the present inventor is engaged in the manufacturing development and design experiences of Related product for many years, for above-mentioned target, Utility model of the design with after scrupulous assess, finally giving a true tool practicality in detail.
