The specific embodiment

Be to reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, to according to its specific embodiment of liquid injection apparatus, structure, feature and the effect thereof that the utility model proposes, be described in detail as follows.

The 1st, encapsulating the liquid container of picture shampoo etc., its upper end has cap body 2 to cover.

The 3rd, the nozzle assembly of the upper horizontal of liquid container 1 installing, the one end has the jet 4 of the liquid of atomizing of liquids container 1, and the other end has been installed and has been connected to the upper part that aforementioned cap body 2 can be supported the vertical piston office 5 that moves up and down.

Therefore, these piston office 5 terminal connections fluid path pipe 22 described later.Again, in the drawings, the 6th, plate machine pull bar, form little " L " font of a pair of positive accumbency, hold nozzle assembly 3 under the arm, be designed to its top and be connected at the upper surface place of nozzle assembly 3, rear end part then engages from the upper end of the outstanding support and control device 7 of cap body 2 with pivot.

But, the liquid injection apparatus of this plate type formula is well known general office, omit its detailed structure explanation, emphasis is: by the operation of repeatedly implementing " hold then and decontrol " plate machine pull bar, ball valve described later (ball valve) action in the piston office 5 is got up, the liquid of liquid container 1 is drunk up, take nozzle assembly 3 as medium, be ejected into the outside from jet 4.

Only at this embodiment, piston office 5 is vertical, and its upper end is major diameter the part 8 and lower end becomes small diameter portion 9, forms section poor (step) part 10 in each coupling part.

Again, particularly in Fig. 2 and Fig. 3, the 12nd, the limit, upper end has the horizontal slide that 10 flat 13 is divided in the segment difference section that butts up against aforementioned piston office 5; And its two side portions by the support and control device 7 free horizontal slips of aforementioned cap body 2 supporting.

The length of this horizontal slide 12 is more than 2 times of diameter of the major diameter part 8 of aforementioned piston office 5, at one side place, when with major diameter part 8 in line the time, have the moon at the first quarter shape first quarter moon shape recess 14 that piston office 5 is moved up and down, its two ends are designed with rib (brim) 15.

Yet, present the utility model liquid injection apparatus body, with storage or carrying or show or when the state of storing obsolete, aforementioned levels slide assemblies 12 is breakked away, arrival does not have the flat 13 state parts of recess 14, and the major diameter part 8 of piston office 5 and small diameter portion 9 are divided 10 local mutually collocation in the formation segment difference section.

Its result, under the not uses such as carrying or storage or displaying state, even touch because of carelessness aforementioned panels machine pull bar 6, since the segment difference section divide 10 and the pairing of horizontal slide 12 engage, the action of this plate machine pull bar 6 is obstructed, therefore the liquid in the liquid container 1 can't rise, and does not just have the anxiety that liquid gushes out from the jet of nozzle assembly 3.

When the utility model liquid injection apparatus body uses, aforementioned levels slide assemblies 12 is breakked away recess 14 is placed on the vertical straight line with the major diameter part 8 of piston office 5 again.

Its result can freely move up and down owing to plate machine pull bar 6 makes piston office 5, thereby the liquid in the liquid container 1 is risen, and relevant liquid just can be from the jet ejection of nozzle assembly 3.

Moreover in the utility model, even use at upright or handstand state, the liquid in the container does not have the embodiment of the injector device of the anxiety that escapes to the outside yet, is shown in the amplification key diagram of Fig. 5 and Fig. 6.That is, in the drawings, the 17th, the upright dual-purpose operating assembly that stands upside down has vertical paired the first path 18 and alternate path 19.

In Fig. 5, the upper end of the first path 18 connects the end of aforementioned piston office 5, and then the lower end of this operating assembly 17 connects vertical connecting path 21 take horizontal passageway 20 as being situated between, and its end is connected to the upper end that is configured in the interior fluid path pipe 22 of liquid container 1.

Then, at first ball valve (23) of aforementioned connecting path 21 interior intercalation diameters less than these path 21 internal diameters.Again, the upper part of this connecting path 21 is provided with recess 24, and when the first ball valve 23 was positioned at the top, the liquid flow in the liquid container 1 can not cause trouble; And the end portion of connecting path 21 is then from the upper part of inboard intercalation aforementioned liquids path pipe 22, and the first ball valve 23 can form closely pairing and engages with the upper part of this fluid path pipe 22.

The end of aforementioned alternate path 19 connects the mid portion of aforementioned the first path 18, and the upper end then is opened in the top in the liquid container 1; Again, in this alternate path 19, the intercalation diameter is less than the second ball valve 25 of alternate path 19 internal diameters.

Moreover in the upper part of aforementioned alternate path 19, the second ball valve 25 can be installed in the places such as the first ledge 26 in the liquid container 1 that can not fly out; Again, with the first path 18 coupling parts, can install not second ledge 27 that can fly out to the first path 18 directions, these designs all are necessary.

Again, the upper part of aforementioned alternate path 19 makes clathrate 28, when the second ball valve 25 is positioned at the upper part of alternate path 19, must be designed in liquid container 1, and liquid can enter alternate path 19, and this is very important.

Again, in now general erectility use, use plate machine pull bar 6 that piston office 5 is moved, then the liquid in the liquid container 1 raises up the first ball valve 23 in the connecting path 21 from fluid path pipe 22, around it, take horizontal passageway 20 as being situated between, enter piston office 5 by the first path 18, be subject to back pressure (back-pressure), process nozzle assembly 3, eject from jet 4.

Moreover the liquid in the liquid container of this situation 1 is on the one hand because the suction of piston office 5, by forcibly towards the direction of piston office 5; On the other hand, in this simultaneously, the second ball valve 25 of alternate path 19 is positioned at the lower end of alternate path 19, has stopped and being communicated with of this first path 18, and therefore, relevant liquid can be towards the direction of alternate path 19.

Next, such as the liquid container 1 of Fig. 6 in the upper end, that is ejector body 16, when the situation that the handstand state of upper (upside-down) uses is got a foothold with so-called head in the lower end, liquid in the liquid container 1 can not stayed the bottom of liquid container 1 but become the state that accumulates towards the direction of ejector body 16, is dipped in the alternate path 19 from the clathrate 28 of alternate path 19 yet stream simultaneously.

Herein, with plate machine pull bar piston office 5 is moved, then the liquid of this alternate path 19 enters piston office 5 by the first path 18, is subject to back pressure (back-pressure), process nozzle assembly 3, ejects from jet 4.
