Description
Technical field
Hand-held compression sprayer is the utility model is related to, more particularly to the anti-error pressure of hand-held compression sprayer switch
Self-locking device.
Background technology
Hand-held compression sprayer is a kind of common family expenses, gardening sprayer, is made up of, passes through inflating pump and liquid bottle
Inflating pump forces the liquid in liquid bottle to be sprayed from shower nozzle toward pressurization is inflated in liquid bottle.Conventional hand-held compression sprayer, generally
It is convenient and practical using the opening and closing of pressing switch press plate control valve, but this structure works as hand there is potential safety hazard
Or other external force will produce switch when unexpectedly acting on switch press plate and open by mistake.Therefore the applicant has once applied for China
Patent of invention 201610705058.5, patent name are the foolproof apparatus of switch " hand-held compression sprayer ", the patent
Self-locking spring slice is mainly set on handle, and the bottom of self-locking spring slice is connected with handle, and self-locking spring slice top sets crotch, switch
Through hole is formed with pressing plate, self-locking spring slice blocks switch press plate through through hole by crotch, prevents from opening by mistake, but it has the drawback that：
Due to self-locking spring slice in order to make it have certain elasticity, therefore wall thickness is relatively thin, when people are pressed onto switch press plate by mistake, if firmly slightly
A little louder, the support force of self-locking spring slice is not enough to support switch press plate, then self-locking spring slice can be caused to deform, and causes liquid
Still it is ejected, therefore the structure still has certain potential safety hazard.
The content of the invention
The shortcomings that the purpose of this utility model is to overcome prior art to exist, there is provided one kind can press switch when using
Plate maintains a normally open state, carries out limited support to switch press plate when not in use, and support force is strong, prevents the hand-held pressure of pressure by mistake
The anti-error pressure self-locking device of contracting sprayer switch.
The technical scheme of anti-error pressure self-locking device of the utility model hand-held compression sprayer switch is：Including liquid bottle and
Bottle cap, sets inflating pump under bottle cap, and in inflating pump insertion liquid bottle, the front side connection spray gun of bottle cap, the head of spray gun sets shower nozzle,
The rear side of bottle cap connects handle, and switch press plate is set on handle, it is characterised in that：Chute is provided with described switch press plate, it is sliding
Groove is formed with baffle plate on side, and lock is set on switch press plate, draw runner and catch is formed with lock, is formed between draw runner and catch
Spring groove, spring is set in spring groove, back-off is formed with draw runner, sliding-tongue is set under switch press plate, jack is provided with sliding-tongue, fallen
The back side phase clamping through chute and jack and sliding-tongue is detained, hook is formed with sliding-tongue, is formed with limiting plate on handle, in limiting plate
Hook hole is provided with, hook is engaged with the upper end of limiting plate or hook hole.
The utility model discloses a kind of anti-error pressure self-locking device of hand-held compression sprayer switch, when being sprayed
When, stir lock backward with finger, the catch of lock extrusion spring backward, latch and drive sliding-tongue to be moved rearwards through back-off, make cunning
Hook on tongue is moved rearwards, and now limiting plate can not block hook, can be pressed downward switch press plate with finger, be made the spray of sprayer
Head is opened, and can be sprayed；And after finger unclamps lock, promote lock to move forward in the presence of spring-return power, lock
Back-off drive sliding-tongue forward, the hook of sliding-tongue is caught in the hook hole of limiting plate forward, hook blocked by hook hole, even if
Finger is unclamped, also switch press plate can be enable to be always maintained at pressed status, now the shower nozzle of sprayer is in normally open；If do not spray
During mist, lock is stirred backward again with finger, latches and drives the hook of sliding-tongue to deviate from hook hole backward through back-off, make switch press plate
Reset upwards, then unclamp finger, spring promotes forward lock under restoring force effect, latch through back-off drive the hook of sliding-tongue to
Preceding movement, now top of the hook in limiting plate, is pressed even if occurring to miss, and position-limiting action is played in the upper end of limiting plate to hook,
Hook and sliding-tongue is set not to push, and the switch press plate being connected with sliding-tongue can not also push, and play anti-error pressure effect.This programme hand
The anti-error pressure self-locking device of formula compression sprayer switch is held, is latched by being set in the top of switch press plate, under switch press plate
Side sets sliding-tongue, latches and is connected through back-off through switch press plate with sliding-tongue, drives hook movable by finger, then profit
Coordinated with the upper end of hook and limiting plate, play the effect spacing to switch press plate, and linked up with and coordinate with the hook hole of limiting plate,
The normally opened effect of mister head is played, function is more, easy to operate, and limiting plate and hook are all hard plastic injection molding shapings,
Wall is thicker, and support force is strong, therefore will not deform easily, safe to use so as to ensure.
The anti-error pressure self-locking device of the utility model hand-held compression sprayer switch, is formed with retaining on described hook
Muscle.There is retaining muscle, when hook is caught in hook hole, the retaining muscle of protrusion hooks limiting plate, prevents hook abjection hook hole.
