Abstract

The utility model relates to an adjustable block-proof nozzle used for liquid cosmetic or medicine atomizer cans, which is composed of a nozzle casing, an air cylinder, a piston, a spring, a liquid feeding valve, a liquid discharging valve and a pressure head whose spout is provided with a spout adjustable device which can be used for adjusting the liquid atomizing quantity. The opening of the spout can be adjusted to be suitable for different viscidity liquid and prevent the clogging of the spout.

Description

Adjustable block-proof nozzle

The utility model relates to the shower nozzle of a kind of liquid make-up or medicine spray affair jar usefulness, particularly a kind of adjustable anti-blocking shower nozzle.

In the prior art, a liquid make-up or a medicine spray affair jar shower nozzle of upward installing, generally be made up of the cylinder in the nozzle housing, piston, spring, feed liquor valve, tapping valve and pressure head, the leakage fluid dram of tapping valve is communicated with the spout on the pressure head, and liquid directly sprays from spout.Because ejection liquid will reach the requirement of atomizing, the nozzle diameter on the pressure head is very little, and spout is very easily blocked in the use.

The shower nozzle that provides a kind of spout adjustable is provided the purpose of this utility model, stops up to prevent spout, can adapt to the use of different viscosities liquid simultaneously.

For achieving the above object, the utility model adopts following technical proposals: this adjustable anti-blocking sprayer is the same with prior art to include the nozzle housing that connects fluid reservoir, be placed in nozzle housing interior cylinder, piston, spring, feed liquor valve, tapping valve and pressure head.Be characterized in: the spout adjusting device that adjustable spouting liquid is housed at the spout place of pressure head.Like this,, adapt to the use of different viscosities liquid, prevent that spout from stopping up with regard to the aperture of eyelid.

Spout adjusting device of the present utility model can be designed to: a shunt head is installed at the spout place at pressure head, and topped a slice swirl plate screws on adjusting nut then on the shunt head.The shunt head intracavity bottom has two through-hole alignments two through holes on the swirl plate, and two grooves are arranged on the swirl plate, and two through holes are linked up with the centre bore on it with tangential, and the centre bore of bellmouth aligning swirl plate is arranged on the adjusting nut.The spout of liquid in the pressure head flows into the inner chamber of shunt head, flows into swirl plate through the shunting of two through hole, tangentially flows into wherein heart hole by two grooves on the swirl plate again, makes liquid stream eddy flow, then the bellmouth ejection from the adjusting nut and atomizing.Can reach the gap that changes between swirl plate and the shunt head by adjusting the elasticity of adjusting nut, thereby change spouting liquid, adapt to the use of different viscosities liquid, and can not stop up.Bellmouth on the adjusting nut can stop up more greatly and not, because the eddy flow of liquid stream, atomizing effect is good.

The utility model has conspicuous advantage compared with prior art: because spout of the present utility model place installed the spout adjusting device, can adapt to the use of different viscosities liquid and not blocked; Because the spout adjusting device makes the liquid eddy flow, atomizing effect is good, and need not make orifice design very little, so also be difficult for stopping up.

The drawing explanation of accompanying drawing:

Fig. 1 is the structural representation of an embodiment of the utility model.

Fig. 2 is that the A of part 16 among Fig. 1 is to view.

Label representative in the accompanying drawing: 1--adjusting nut; The 2--shunt head; The 3--pressure head; The 4--piston; The 5--cylinder; The 6--slotted hole; The 7--steel ball; 8--feed liquor valve; The 9--spring; The 10--pipette; The 11--fluid reservoir; The 12--nozzle housing; The 13--tapping valve; The 14--sealing gasket; The 15--cover cap; The 16--swirl plate; The 17--centre bore; The 18--through hole.

An optimum implementation of the present utility model is: referring to Fig. 1 and Fig. 2, this adjustable anti-blocking sprayer is made up of nozzle housing 12, cylinder 5, piston 4, spring 9, feed liquor valve 8, tapping valve 13 and pressure head 3.The spout adjusting device is installed at the spout place of pressure head 3.The spout adjusting device is at the spout place of pressure head 3 shunt head 2 to be installed, and topped a slice swirl plate 16 screws on adjusting nut 1 then on the shunt head 2.Shunt head 2 intracavity bottoms have two through-hole alignments two through holes 18 on the swirl plate 16, have two grooves that two through holes 18 are linked up with the centre bore 17 on it with tangential on the swirl plate 16, and the centre bore 17 of bellmouth aligning swirl plate 16 is arranged on the adjusting nut 1.Tapping valve 13 is a needle-valve, and feed liquor valve 8 is a non-return valve.The piston rod cavity leakage fluid dram coupling of the needle-valve of tapping valve 13 and piston 4, the leakage fluid dram of piston 4 is communicated with the spout of pressure head 3.The upper end tight fit of the bottom of tapping valve 13 and feed liquor valve 8 connects and composes an inner chamber, and its inner chamber is settled the steel ball 7 of tapping valve 8, and this inner chamber is communicated with piston 4 lower cylinder 5 inner chambers by the slotted hole 6 on the tapping valve 13.The centre bore of feed liquor valve 8 is communicated with fluid reservoir 11 inner chambers by pipette 10.Feed liquor valve 8 lower end mounting spring 9.Nozzle housing 12 is connected with fluid reservoir 11 with screw thread, cushions sealing gasket 14 therebetween.Cover cap 15 is installed on nozzle housing 12 tops.

Its operation principle is: when pressure head 3 pressurizeds, it is descending to drive piston 4 and tapping valve 13 and feed liquor valve 8, spring 9 pressurizeds, the leakage fluid dram of sealing tapping valve 13.When pressure head 3 loosened, under the effect of spring 9, it was up to drive feed liquor valve 8, tapping valve 13 and piston 4, and under the suction function, liquid backs down steel ball 7 by feed liquor valve 8 centre bores in cylinder chamber, flowed in cylinder 5 chambeies by slotted hole 6.Stress on pressure head 3 again, when piston 4 is descending, liquid pressurized in the cylinder 5, the steel ball 7 of feed liquor valve 8 cuts out inlet, hydraulic pressure overcomes the pressure of spring 9 and opens the needle-valve of tapping valve 13, so liquid is from the piston rod centre bore of piston 4 pressure head 3 inner chambers of flowing through, then from the bellmouth ejection of the adjusting nut 1 of spout adjusting device.Above-mentioned action, then intermittent spray circulate.
