Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As depicted in figs. 1 and 2, one embodiment of the invention, a kind of folding plays ink-filling bottle, and it comprises bottle 1, needle stand 2 and liquid injection pipe 3; Described bottle 1 has the bottleneck 4 of upper end open; Be provided with between described bottle 1 and described bottleneck 4 and roll over bullet portion 5, described bottle 1 bottom surface is indent elastic surface; Described needle stand 2 is installed on described bottleneck 4, and described needle stand 2 comprises the portion of being located thereon and for the supporting seat 21 of pen 7 handwriting grafting and can be positioned at its underpart and the casing seat 22 fixedly sleeved with described liquid injection pipe 3; The upper end of described liquid injection pipe 3 is exposed to described supporting seat 21 outside and is in communication with the outside, and the lower end of described liquid injection pipe 3 is resisted against described bottle 1 bottom surface, and described liquid injection pipe 3 is provided with the flexible pipe 6 be communicated with described bottle 1 inside; Described supporting seat 21 is installed with the first seal 8 be tightly connected with pen 7 handwriting; Described supporting seat 21 is provided with the passage 9 that described bottle 1 inside can be made to be in communication with the outside.
Introduce operation principle of the present invention below: the present invention mainly utilizes to be provided with between bottle 1 and bottleneck 4 and rolls over bullet portion 5 descending and resilience resets to the pressurized realizing needle stand 2, simultaneously utilize the liquid injection pipe 3 be fixed on needle stand 2 push up the indent elasticity bottom surface of pressure bottle body 1 to realize the air pressure change in bottle, thus reach formerly Hui Moyu in the object of rear refilling.
When the bottle cap 10 of ink-filling bottle of the present invention is opened, the bottom surface of described bottle 1 is reset mode, namely in concave configuration, described needle stand 2 and bottleneck 4 are in upper, described bottle 1 volume is in minimum state, described bottle 1 is in communication with the outside by the passage 9 on described supporting seat 21, makes the air pressure everywhere in whole ink-filling bottle be equal to ambient pressure value.
When described needle stand 2 and bottleneck 4 are subject to pressing from pen 7 and in the process dynamic to bottom offset, because described first seal 8 is tightly connected with pen 7 handwriting, whole bottle 1 inside is made to be in sealing state, meanwhile, the indent elasticity bottom surface that described liquid injection pipe 3 lower end heads on described bottle 1 presses down and expands outwardly, described bottle 1 volume becomes large gradually, causes the air pressure of bottle 1 inside to decline gradually, and then makes the air pressure of described bottle 1 inside be less than air pressure in pen 7 barrel; Again because the inside of described bottle 1 is communicated with the barrel of pen 7 by liquid injection pipe 3, like this, in barrel, air and excess ink all can flow into described bottle 1 along described liquid injection pipe 3, thus realize back black action.
After completing above-mentioned time black action, pen 7 barrel should be kept to be communicated with certain hour with described liquid injection pipe 3, described needle stand 2 and bottleneck 4 is made to rise until become upper gradually from bottom under the acting in conjunction in the indent elasticity bottom surface of described bottle 1 and folding bullet portion 5, in this process, described bottle 1 volume diminishes gradually, the air pressure of bottle 1 inside is caused to rise gradually, and then make the air pressure of described bottle 1 inside be greater than air pressure in pen 7 barrel, like this, ink (or solution) in bottle 1 flows to barrel through liquid injection pipe 3, thus realizes refilling action.
When bottle 1 air pressure inside is recovered equal with ambient pressure (being also the air pressure in pen 7 barrel), remove pressure and extract a tail, complete refilling action.
It should be noted that, the Volume Changes size of bottle 1 should slightly larger than or equal the Volume Changes size of pen 7 barrel, to guarantee equivalent volumes refilling.
As the above analysis, folding provided by the invention plays two kinds of functions that ink-filling bottle has Hui Mo and refilling, feature easy to use, simple to operate.Again because first completing back black action before refilling action, there is not the problem that refilling process ink inside is excessive.
Folding provided by the invention plays ink-filling bottle and also comprises bottle cap 10, and described bottle cap 10 is covered on described bottleneck 4, and described bottle cap 10 is provided with the second seal 11 be tightly connected with the upper end of described liquid injection pipe 3.Described second seal 11 preferably adopts flexible rubber or silica gel to be made, its center is provided with a blind hole 12, when ink-filling bottle leaves unused, the upper end of described liquid injection pipe 3 is inserted in described blind hole 12, be interference fit between this blind hole 12 and upper end of described liquid injection pipe 3, so can ensure when ink-filling bottle leaves unused, even if overturn, also can ensure that the ink in bottle can not be excessive along liquid injection pipe 3.Further, described bottle cap 10 is provided with the 3rd seal 13 that described passage 9 can be sealed.Described 3rd seal 13 preferably adopts flexible rubber or silica gel to be made.When described bottle cap 10 covers tightly described bottleneck 4, described passage 9 is just in time adjacent to sealing by described 3rd seal 13, described bottle 1 inside is made to form the separate space of a sealing, prevent in transportation because ink-filling bottle placement location is incorrect, during as being inverted, ink in bottle flows into by described passage 9 in the connection crack between described bottle cap 10 and bottleneck 4, has ink and adheres to the phenomenon of even dripping, affect the normal use of ink-filling bottle when opening bottle cap 10.
In the present embodiment, owing to considering that described liquid injection pipe 3 upper end is for connecting pen 7 barrel, its caliber is unsuitable excessive, to guarantee in bottle that ink enters barrel with flow velocity slowly, again owing to considering that described liquid injection pipe 3 lower end is for pushing up pressure bottle body 1 bottom surface, its caliber is unsuitable too small, prevents stress from concentrating and causes bottle 1 bottom surface fatigue wear.Therefore, when designing described liquid injection pipe 3, it comprises needle tubing 31 and push pipe 32; Described push pipe 32 is fixedly sleeved in described casing seat 22, be communicated with described bottle 1 inside by described flexible pipe 6 in the tube chamber that described needle tubing 31 lower end is plugged in described push pipe 32 upper end, the upper end of described needle tubing 31 is exposed to described supporting seat 21 outside and is in communication with the outside; Described push pipe 32 lower end is resisted against described bottle 1 bottom surface.
More preferably, described flexible pipe 6 lower end extends described bottle 1 bottom periphery, during to guarantee that bottle 1 bottom surface indent resets, and normal refilling when quantity of ink is less in bottle.
More preferably, described bottle 1 adopts elastoplast blow molding, and its structure is simple, low cost of manufacture.
Above disclosedly be only preferred embodiment of the present invention, certainly can not limit the interest field of the present invention with this, therefore according to the equivalent variations that the present patent application the scope of the claims is done, still belong to the scope that the present invention is contained.
