Abstract
Disclosed is an anti-return air-blast atomizer which is characterized in that, firstly, a spring 27 installed inside a spring sleeve 9 is a stainless steel spring, and the two ends of the spring respectively contact with a glass ball 12, secondly, a valve seat 14 is provided with air discharging holes 23, and a water sealing ring 21 is arranged between an inflator 15 and a small cover 22. The utility model guarantees the no returning of the liquid medicine and the air compression and prolongs the time of automatic atomization. The utility model has the advantages of perfect seal effect, easy control of opening and closing, convenient operation and safe utilization.
Description
One, technical field:
The utility model relates to a kind of sprayer unit, especially a kind of anti-return air-blast atomizer.
Two, background technology:
At present, the sprayer that everybody was familiar with is mainly by the spray lid, shower nozzle, bent sub, outlet pipe, storage cylinder of water, leather cup, valve seat, inflator, steam vent, piston tube, handle, flexible pipe, back-water valve (BWV), spring, counterweight, filtering head, compositions such as sebific duct, this sprayer is to crops, when nursery and fruit tree are sprayed agricultural chemicals, liquid medicine and air pressure easily return in the inflator, jeting effect is bad, switch is wayward, and after entering gas in the inflator, its auto spraying time shortens, and in implementing spray process, needs repeatedly to absorb water in storage cylinder of water, can not guarantee to spray and carry out continuously, the sprayer soup of this structure easily leaks the operator on hand after entering in the inflator, and sealing is poor, use dangerous, after the storage cylinder of water internal gas pressure descended, soup can flow backward in the storage explosive barrel, can not guarantee need not absorb water with air-breathing.
Three, summary of the invention:
The purpose of this utility model provides a kind of anti-return air-blast atomizer, by changing the structure of existing sprayer, solves liquid medicine and air pressure and easily flows backwards, and switch is wayward, and the auto spraying time is short, and liquid medicine easily leaks, and uses unsafe problem.
Concrete scheme of the present utility model is: comprise spray lid, shower nozzle, bent sub, outlet pipe, nut, rubber hose coupling, " O " type circle, storage cylinder of water, spring housing, apopore, glass marble, leather cup, valve seat, inflator, piston tube, handle, plastic mattress, flexible pipe, back-water valve (BWV), water shutoff circle, tegillum, steam vent, piston valve, pin, spring, counterweight, filtering head, sebific duct, nut seat, it is characterized in that: the spring that A. is installed in the spring housing is a stainless steel spring, and its two contacts with glass marble respectively; B. valve seat is provided with steam vent, is provided with the water shutoff circle between inflator and the tegillum.
Adopt such scheme, guaranteed that liquid medicine and air pressure do not flow backwards, prolonged the auto spraying time, its good airproof performance, switch is easy to control, and is easy to operate, safe in utilization.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model.
Five, the specific embodiment:
Please see Figure 1, the utility model mainly by spray cover 1, shower nozzle 2, bent sub 3, outlet pipe 4, nut 5, rubber hose coupling 6, " O " type circle 7, storage cylinder of water 8, spring housing 9, apopore 10, glass marble 12, leather cup 13, valve seat 14, inflator 15, piston tube 16, handle 17, plastic mattress 18, flexible pipe 19, back-water valve (BWV) 20, water shutoff circle 21, tegillum 22, steam vent 23, piston valve 24, pin 25, spring 27, counterweight 28, filtering head 29 sebific ducts 30, nut seat 31 etc. form.It is characterized in that: the spring 27 that A. is installed in the spring housing 9 is stainless steel springs, and its two contacts with glass marble 12 respectively; B. valve seat 14 is provided with steam vent 23, is provided with water shutoff circle 21 between inflator 15 and the tegillum 22.
As can be seen from Figure 1, the water inlet end of handle 17 is provided with back-water valve (BWV) 20, is provided with plastic mattress 18 and glass marble 12 in the back-water valve (BWV) 20.The inflator 15 that stretches in the storage cylinder of water is threaded with storage cylinder of water 8.
Operation principle of the present utility model is, filtering head 29 is connected on the liquid medicine bucket or directly puts into the liquid medicine bucket, pulling handle 17, liquid medicine sucks in the inflator 15 through handle 17 and piston tube 16 by flexible pipe 19, the pressure of liquid medicine promotes glass marble 12, glass marble 12 compresses stainless steel springs 27 after the apopore 10 on the spring housing 9 enters in the storage cylinder of water 8, when the pressure in the storage cylinder of water 8 reaches certain value, stainless steel spring 27 promotes glass marble 12, makes glass marble 12 block inflator 15 water inlets, prevents the gentle stream that overwhelms of liquid medicine, liquid medicine in the storage cylinder of water 8 is through sebific duct 30, outlet pipe 4, bent sub 3, shower nozzle 2, the aperture from nozzle cap 1 sprays, and implements spraying operation.After the pressure in the storage cylinder of water 8 descends, the apopore 10 of liquid medicine on spring housing 9, piston valve 24, valve seat 14 piston tube 16 enter in the handle 17, are blocked by the back-water valve (BWV) 20 of handle 17 belows, liquid medicine can not be flowed backward in the liquid medicine bucket, guarantee normal suction and air-breathing.
