The parts can be reduced, the production efficiency can be improved, and the cost can be lowered.

Description

Anti-leak flat device of sprayer

The utility model relates to a kind of sprayer, particularly a kind of leakage prevention sheet device with leakage prevention sheet and metal shell.

Sprayer is common article commonly used, and its range of application is rather extensive, and is divided into antomobile sprayer with the spray of pushing away (as: spray paint can, desinsection flow container, spray glue jar, or the like) again and manually pushes the sprayer (as: scent flask) of ejection; No matter and be antomobile sprayer or hand sprayer, often have the seepage situation to take place, reason must possess bigger pressure earlier before nothing more than the liquid ejection, can be effectively sprays with the state of atomizing; Because hydraulic pressure increases, liquid very easily goes out from the place, binding site slit of container and sprayer seepage flow, causes user's hand to be infected with and big sense puzzlement.

Probing into the seepage place must set about being inquired into from structure, is illustrated in figure 1 as one of known spray structure example, and its combination system comprises:

Bottle mouth position on the container H of a splendid attire liquid material, combine with bottle by a crown cap D, crown cap is again in conjunction with a capouch B and leak-stopping sheet C simultaneously, in the cage in conjunction with a retaining pump E and stretch in the bottle, termination connects a suction pipe J under the retaining pump E, stretch into the bottom of liquid tank H downwards, retaining pump E goes up a sheathed diversion piston tube A, the downward again sheathed piston valve F of piston tube A is in the retaining pump, piston valve F is resisted against in the retaining pump by spring G, then push shower nozzle I, promptly finish a press-type spray device on diversion piston tube A top sheathed.

Its start system does the spraying of phase I and the retaining of second stage, all in once pushing, finish, sectional structure as shown in Figure 2, push shower nozzle I and make it descending when forcing in, descend together with driving diversion piston tube A, the diversion piston tube then presses piston valve F to descending, closing and seal separation retaining pump by pipe box in piston valve F decline back and the retaining pump E is the first half and Lower Half, then be present in the interior liquid material of the retaining pump first half promptly because of sealing and be subjected to continuations of diversion piston tube A and piston valve F to oppress that the space dwindles and pressure heightens, and then from the joint of piston valve F top and diversion piston tube A, compressing piston valve and spring be to descending and must produce a space and make pressure fluid climb sharply to diversion piston tube A, and by pushing shower nozzle I ejection; When shower nozzle I is pushed in relieving, spring G pushes up back piston valve F, order was that the retaining pump first half of enclosed area recovers to be communicated with Lower Half originally, then rise to the vacuum that the first half caused at piston valve F, can make the liquid of liquid material container H, along suction pipe J, Lower Half and be supplemented in the first half rapidly, so, be filled the liquid material in the first half again, be the ejection state (as Fig. 1) of preparing, so only need depress again and push shower nozzle I, the liquid of this first half promptly because of pressurized from diversion piston tube A to the upper punch liter, and then be vaporific ejection pushing shower nozzle I.

By above-mentioned structure as can be known, liquid compression when ejection phase I of known configurations since hydraulic pressure increase, before ejection not, promptly may be by the outside seepage of the leakage of K, because K is the movement joint place of plastics capouch B and diversion piston tube A, its very easily seepage be no doubt.

In addition, above-mentioned known construction is in producing very inconvenience of fit on, in other words, it is the thing (because of both all are rigid plastics) of very requiring great effort that desire is clamp-oned pump E in the capouch B, and is equipped with leak-stopping sheet C, metal enclosing cover D etc. again, numerous parts make assembler's duration, and are not inconsistent economic benefit.

The sprayer leakage prevention sheet device that provides a kind of leak preventing effect good, the puzzlement that sprayer person hand capable of reducing using is infected with the liquid material are provided main purpose of the present utility model.

Another purpose of the present utility model is to provide a kind of sprayer leakage prevention sheet device that reduces production costs, and uses and increases economic efficiency.

Now for of the present utility model one preferable embodiment, and conjunction with figs. is described as follows, and believes that feature of the utility model and effect can obtain clear understanding by following explanation.

Fig. 1 is the cutaway view of the inactive state of known sprayer;

Fig. 2 is the cutaway view of the actuator state of known sprayer;

Fig. 3 is the three-dimensional exploded view of the utility model sprayer leakage prevention sheet device;

Fig. 4 is the utility model sprayer assembled sectional view.

See also shown in Figure 3ly, sprayer leakage prevention sheet device of the present utility model consists essentially of a leakage prevention sheet 1 and a metal shell 2.Leakage prevention sheet is to be made by the material with leakproof effect (as rubber), it makes the capful shape, edge clipping 13 in the annular of have the prominent ring portion 11 of ring portion 10 on the similar marginal ridge, similar crown, inwardly being stretched out by the leak-stopping circle edge 12 of the inside drawdown in crown center and by last ring portion 10.Metal shell 2 then by foil make, appearance electrodepositable or lacquer handle, it is according to the shape of leakage prevention sheet 1, make edge 21 on the plane ring-type according to sample, the bead 22 of projection such as crown, and the top of bead 22 is one than annular distance 23 on big, and only staying in a narrow margin a button side ring 24, upper limb 21 is Zhe down again, forms a circle lateral margin 20.

As shown in Figure 4, the combination of the utility model is to make edge hook edge clipping 13 within leak-stopping sheet 1 on the retaining pump 3, and leak-stopping circle edge 12 then is for the therebetween up and down person of piston tube A; Edge 21 is close to corner edge on the ring portion 10 on the metal shell 2, its lateral margin 20 then be in order to the container H person of combination.

This wherein, but the leak-stopping circle edge 12 with leakage prevention sheet 1 of elasticity is that closed loop is affixed on piston tube A, and does not hinder its person of moving up and down, end is then overlayed in the bottleneck of container H by upper limb 21 under the last ring portion 10, and reaches the purpose of leak-stopping.

In addition because leakage prevention sheet 1 has the elasticity of softness, can buckle in the interior edge clipping 13 so retaining pump E is very light, metal shell 2 then has been the effect of the housing of packing leakage prevention sheet and reinforcing leakage prevention sheet, make leakage prevention sheet 1 and metal shell 2 be issued to leakproof, assemble easy effect, and reach the purpose that has the sprayer of improvement seepage and reduce its manufacturing cost in one gentle one cooperation just.

Comprehensive the above as can be known, the utility model structure is simplified, combined and instant and effect are distinguished, really can promote special efficacy and economic benefit that common structure does not have.
