Description

The nozzle arrangements of air pressure watering can

Technical field:

The utility model relates to a kind of nozzle structure-improved of portable air pressure watering can.

Background technology:

The kind of existing watering can is a lot, and roughly being divided into is pressure type and pressure storage type two classes, and the former air pump and nozzle connect to one, can spray certain amount of fluid by compression pump at every turn, are used in the packings of product such as perfume bottle, shower lotion more; And the latter promptly mostly is special-purpose watering can product, and its bottle has hermetically-sealed construction, can bear certain air pressure, during operation, can produce continuous water spray or spray effect.The structure of watering can comprises kettle body, pot lid, be installed in the inflator assembly on the pot lid and the nozzle assembly of band valve, nozzle assembly is installed in the end of valve pocket, be placed with a spool in the valve pocket, this spool is conflicted on the water inlet bell of nozzle assembly, forms the effect of switch; Described spool is connected with a valve rod, and valve rod passes the valve pocket bottom, and is connected by one handle, pushes and moves after handle can spur valve rod, and High-Pressure Water can spray on nozzle smoothly by the water inlet bell; Be arranged with a spring on the valve rod, be pivoted with a seal ring between spring and the valve pocket bottom, reach the anti-purpose of leaking and leaking gas with this.There is certain defective in the design of this spool, causes watering can usually to leak outward from valve rod, especially is non-operating condition.How to design a kind of more rational nozzle assembly, promptly become the object of the utility model research.

Summary of the invention:

The purpose of this utility model is that a kind of spool different parts of design is blocked in valve inleting water mouth place, formation is opened and the nozzle arrangements of the air pressure watering can of pass effect.

Technical solutions of the utility model are achieved in that a kind of nozzle arrangements of air pressure watering can, comprise pot lid, be installed in the nozzle assembly of pot lid beak portion and the valve member in the pot lid chamber, it is characterized in that described valve member comprises valve body, slide pivot is located at spring, spring bearer plate, spool and the button back-up ring in the valve pocket and is positioned at button on the pot lid successively; Valve body is fixed in the pot lid chamber, the through hole that it has a valve pocket and radially connects valve pocket, and the outer corresponding through hole disjunctor of valve body has into water interface and water outlet interface, and the water inlet interface can be pegged graft with the sucking tube that inserts in the kettle body, and the water outlet interface can be communicated with nozzle assembly; Spool becomes column structure, and the one end had aquaporin, remains on valve pocket through hole place and slide under action of the spring.During operation, in case button pressed, spool overcomes spring force and moves inward, makes spool cross aquaporin and is communicated with valve open with through hole; Shed the external force of button, spool resets and blocks through hole under the effect of spring, and valve is in closed condition; And the effect of spring bearer plate and button back-up ring promptly is to keep spool when action, the indeformable and generation gap that leaks.

Described pot lid chamber internal fixation has a locating rack, and valve body and button are located on the locating rack preformed hole by the folding climbers of abduction, forms the structure that fixes with pot lid; The preformed hole that button is established button folding pin is a long slot bore, and the actuation of keys stroke is provided, and mat locating rack fixed valve body and button offer convenience to assembling.

The cylinder of described spool has three road ring stiffeners, wherein is evenly equipped with shaft orientation reinforcing rib between twice adjacent annular reinforced rib, and the cylinder between twice adjacent annular reinforced rib has annular groove in addition, constitutes aquaporin.By the design of three road ring stiffeners, both considered sealing property, the contact surface of minimizing and valve pocket reduces the friction between fitting surface again, slides more along sliding lightly.

Described spool cylinder is filled with lubricating oil in the zone by twice adjacent annular reinforced rib and shaft orientation reinforcing rib separation.The water effect of isolating had both been played in the zone that this shaft orientation reinforcing rib is separated, and the placement place of lubricating oil is provided again, at one stroke both.

Described nozzle assembly comprises successively-L type pipe, big spiral shell head, ozzle and small screw head; Water outlet interface in L type Guan Yiduan and the valve body is pegged graft, and the other end is plugged on the big spiral shell nose cone shape porthole; Ozzle is placed between small screw head and the big spiral shell head, and small screw head is screwed on the big spiral shell head, and big spiral shell head is screwed in pot lid beak portion.Change the position of nozzle by L type pipe, moreover can be by the elasticity of rotation adjusting small screw head, the gap length that the mat ozzle is conflicted is with it regulated spray pattern.

Valve body in the utility model nozzle arrangements, its valve pocket and Inlet and outlet water through hole adopt and are arranged vertically, and the mat cylindrical spool slides in valve pocket, produces the state of opening and closing, and avoids the gap of operating portion formation such as button, causes the gas leakage defective of leaking; Cooperated by spring bearer plate and button back-up ring, when making the two-way slip of spool, two ends are all indeformable, do not produce the gap that leaks, and durable in use, prolong the service life of product again.
