【Specific implementation mode】
It elaborates below in conjunction with the accompanying drawings to embodiments of the present invention.
As shown in Fig. 1-63, a kind of adjustable quantitative liquid-spraying cover of the present invention, includes the lid for being connect with container finish
Connecting seat 1 and stretch into the suction pipe 2 in container, 1 upper opening of lid connecting seat and it is interior be equipped with liquid storage cylinder 11, on the suction pipe 2
The feed liquor valve module 3 for controlling suction pipe 2 with liquid storage cylinder 11 conducting or be closed is equipped between end and 1 bottom of lid connecting seat, it is described
1 upper opening of lid connecting seat is movable to be connected with pump head 4, and the hydrojet runner that can be connected to liquid storage cylinder 11 is equipped in the pump head 4
41,4 lower end of the pump head, which is connected with, is placed in the interior liquid made for 11 space of compression liquid storage cylinder in liquid storage cylinder 11 of liquid storage cylinder 11
The piston 6 that body is sprayed by hydrojet runner 41, the piston 6 are equipped with the piston flow that can be connected to hydrojet runner 41 and liquid storage cylinder 11
Road 61, the quantitative liquid-spraying cover further include making the elastic component 5 of 6 elastic reset of pump head 4 and piston and when pump head 4 is with respect to lid connecting seat
After 1 rotation, quantitative regulating mechanism 7 of the changeable piston 6 in 11 movement travel of liquid storage cylinder so that pump head 4 quantitatively sprays liquid
Body.By adjustment quantitative regulating mechanism 7,6 up and down motion stroke of piston then changes, so that empty in piston compression container
Between or liquid storage cavity space quantitative variation occurs, for this purpose, can be allowed to accurately spray quantitative material.
The present invention can be arranged on pump head 4 or be not provided with valve nozzle 43, can spray to accurate quantitative analysis corresponding aerosol, glue
Body, foam or fluid column facilitate the encapsulation of different product to select, certain daily personal care classes, such as liquid detergent, shampoo, shower cream,
Go out what liquid need not spray, then can be not provided with valve nozzle 43 on pump head 4.
As the first specific embodiment of the present invention, as shown in Fig. 1-15, Figure 23-41 and Figure 46-49：
The quantitative regulating mechanism 7 includes that the dynamic adjusting thread 74 being located on pump head 4 saves spiral shell with setting the tone on piston 6 is located at
Tooth 75, the dynamic adjusting thread 74 is the internal thread and external screw thread connecting that can mutually be rotatably assorted with section thread 75 of setting the tone, described
Liquid storage cylinder 11 is equipped with 6 head of piston prevents the spline structure that piston 6 is rotated relative to liquid storage cylinder 11, the spline structure can be by work
The cross section that plug 6 and liquid storage cylinder 11 coordinate is designed as non-circular structure, such as ellipsoidal structure, can also be in piston 6 and liquid storage cylinder
It is vertically equipped with mutually matched guiding fin between 11 and is oriented to groove, therefore when rotating pump head 4,6 turns of 4 opposing pistons of pump head
It is dynamic, and as pump head 4 rotates, piston 6 is moved up and down with respect to liquid storage cylinder 11, piston 6 in liquid storage cylinder 11 corresponding up and down adjustment its
Movement travel in liquid storage cylinder 11.When the movement travel of piston 6 change is small, the substance that pump head 4 sprays then accordingly tails off, on the contrary
It is as the same.
In the first embodiment of the invention, as shown in Fig. 1-15 and Figure 23-30,1 upper opening of lid connecting seat can live
It is dynamic to be connected with lid shell 71, mutual cooperation spline structure is equipped between the pump head 4 and lid shell 71 so that lid shell 71 is with pump head 4
Rotation, and when pump head 4 and lid shell 71 are rotated relative to lid connecting seat 1, piston 6 accordingly along 11 up and down adjustment of liquid storage cylinder its in liquid storage cylinder
11 movement travel.The spline structure can be the elliptical aperture being arranged on lid shell 71 and the cross section being located on pump head 4 in ellipse
Circular central siphon, or positioning recess and positioning protrusion to be located between 71 endoporus of lid shell and pump head 4.
In the first embodiment of the invention, as shown in Fig. 8-15 and Figure 27-30, the invention also includes for pushing tow pump head 4
It is allowed to the compression bar 711 that opposite lid connecting seat 1 and lid shell 71 move upwards and then piston 6 driven to compress 11 space of liquid storage cylinder, it is described
It is outward extended with strut 712 on 71 side wall of lid shell and on the downside of 4 mouth spray of pump head, the middle part of the compression bar 711 is articulated with branch
712 end of bar between 711 upper end of the compression bar extends on the downside of 4 mouth spray of lid shell 71 and pump head, and is worked as by moulded rod 711 certainly
When by holding, compression bar 711 is then rotated around 712 end of strut, and then pushing tow pump head 4 moves upwards 711 upper end of compression bar.In use, using hand
Finger withholds 711 free end of compression bar, and compression bar 711 is then around the articulated shaft rotation that it connect with strut 712 so that pushes up 711 upper end of compression bar
It pushes away pump head 4 to move upwards, piston 4 then moves upwards and compress the space of liquid storage cylinder 11 with pump head 4, and the substance in liquid storage cylinder 11 is then
It is sprayed from 4 accurate quantitative analysis of pump head through hydrojet runner 41.
In the first embodiment of the invention, as shown in Fig. 8-10, Figure 15, Figure 23-41, Figure 46-47, the hydrojet runner
41 oral areas are equipped with valve nozzle 42 can with accurate quantitative analysis spray the fluid column or aerosol of respective substance, institute using the design scheme
Feed liquor valve module 3 is stated to include lower valve port 31 for being connected to suction pipe 3 and piston runner 61 and liquid storage cylinder 11 and movably block
In the bottom spool 32 of lower valve port 31, bottom spool 32 can be the valve core structure of globe valve pearl or other structures.As seen in figs. 8-10,
5 upper and lower ends of the elastic component are connected to respectively between lid shell 71 and piston 6, as shown in Figure 15, Figure 28-29, the elastic component 5
