The utility model is characterized in that plug adopts a hollow structure and connected with the hollow plug rod, a converse-pumping rod is arranged inside the hollow plug rod, the converse-pumping rod is closely matched with the hollow plug rod, and the lower end of the converse-pumping rod is contacted with the round valve body.
Description
Technical field
The utility model relates to a kind of solution distribution arrangement, especially relates to a kind of distributor that moves back and forth guiding valve that has.
Background technology
At present, commonly used solution distribution arrangement is made of distributor body, pump chamber, the valve body that is enclosed within piston, the spring on the plunger rod and is positioned at the plunger below on the market, but owing to can not form negative pressure in the plunger rod inner space, distributor of the prior art can only make solution quantitatively pump, and can not draw back distributor to the solution that is arranged in the nozzle exit outside, and therefore very easily form dropping liquid in use at the nozzle exit end, cause the pollution of solution, or distributor, or the pollution of container.
The utility model content
It is a kind of simple in structure that the utility model provides, and the solution dispenser that has down picking device reasonable in design has solved the technical problem that forms dropping liquid in the prior art in the distributor use easily at the port of export.
The utility model has down the technical scheme that the solution dispenser of picking device is achieved: it comprises the nozzle exit button that distributes from top to bottom, the closing cap that has internal thread, in closing cap, be provided with the hollow plunger rod that communicates with nozzle exit, be positioned at hollow plunger rod and be provided with plunger, between described hollow plunger rod and plunger, be provided with annular piston, the below of described plunger is provided with spherical valve body, form pump chamber between described plunger and the spherical valve body, described plunger is a hollow structure, and communicate with hollow plunger rod, in described hollow plunger, be provided with and take out bar, describedly take out bar and described hollow plunger closely cooperates, described lower end of taking out bar contacts with described spherical valve body.
The utlity model has down the solution dispenser of picking device, wherein, describedly take out the shape of bar rear surface and the surface configuration of spherical valve body matches.Describedly take out bar and the contacted outer end diameter of spherical valve body axially goes up the external diameter at other positions greater than taking out bar.
Compared with prior art, the beneficial effects of the utility model are: take out bar owing to be provided with between plunger and valve body, and take out bar and closely cooperate with plunger all the time, therefore, in the plunger rod reseting procedure, in plunger, form negative pressure, thereby a little solution that remains in the nozzle exit outside after solution can being pumped is drawn back in the distributor, avoid the pollution of solution effectively, reached the pollution that dropping liquid causes for distributor or container.
Description of drawings
Fig. 1 is the cutaway view that the utlity model has down the solution dispenser of picking device;
Fig. 2 is the STRUCTURE DECOMPOSITION schematic diagram of solution dispenser as shown in Figure 1.
Be the explanation of Reference numeral in the Figure of description below:
1---button 2---long spring 3---closing cap
4---plunger rod 5---short spring 6---annular pistons
7---plunger 8---is taken out bar 9---spherical valve bodies

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
By Fig. 1 and Fig. 2 as can be seen, the utlity model has down the nozzle exit button 1 that the solution dispenser of picking device distributes from top to bottom, the closing cap 3 that has internal thread, be used for distributor is installed in the container of needs, in closing cap 3, be provided with the hollow plunger rod 4 that communicates with nozzle exit, be positioned at hollow plunger rod 4, and the plunger 7 that communicates with hollow plunger rod 4, between described hollow plunger rod 4 and plunger 7, be provided with annular piston 6, the below of described plunger 7 is provided with spherical valve body 9, form pump chamber between described plunger 7 and the spherical valve body 9, described plunger 7 is a hollow structure, in described hollow plunger 7, be provided with and take out bar 8, the described bar 8 of taking out closely cooperates with described hollow plunger 7, described lower end of taking out bar 8 contacts with described spherical valve body 9, and the shape of the described rear surface of taking out bar 8 and the surface configuration of spherical valve body 9 match.Described hollow plunger 7 slides up and down along the described bar 8 of taking out, taking out the rear surface shape of bar 8 and the surface configuration of spherical valve body 9 matches, for contacting of bar 8 and spherical valve body 9 taken out in further assurance, described take out bar 8 and spherical valve body 9 contacted outer end diameter can greater than take out bar 8 axially on the external diameters at other positions.
The operation principle that the utlity model has down the solution dispenser of picking device is: annular piston 6 is installed between hollow posts stick harness 4 and the hollow plunger 7, when pushing or during release-push 1, described plunger rod 4, annular piston 6 and plunger 7 pump along the pumping cylinder that is formed by body 1 inner chamber together, thereby limit the volume of pump chamber together.Long spring 2 is arranged between closing cap 3 and the button 1, and therefore, when manually pushing nozzle exit button 1, long spring 2 is compressed into position of rest.
During operation, be applied to the downward Manual pressure on the button 1, the initial period is that plunger rod 4 relative annular pistons 6 are moved down, and is compressed to extreme position up to short spring 5, thereby the valve open that piston 6 is cooperated with plunger 7 forms discharge-channel between plunger 7 and button 1; And make and take out bar 8 and move down and push down spherical valve body 9, make spherical valve body 9 and body 10 sealings.Continue to be applied to the downward pressure on the button 1, annular piston 6 is moved downward in the pumping cylinder that is formed by body 10 inner chambers, by the space that further reduces pump chamber that moves downward of plunger 7, thereby the solution in the pump chamber is compressed, solution is pumped from nozzle exit by above-mentioned discharge-channel.During release-push 1, produce in the moving up of plunger 7 by the restoring force of long spring 2, the valve closes that piston 6 cooperates with plunger 7, and the process that pump chamber enlarges generation negative pressure causes moving on the spherical valve body 9, solution passes through in the access road suction pump chamber.Owing between plunger 7 and spherical valve body 9, be provided with in the distributor of the present utility model and take out bar 8, therefore, after pumping solution, in plunger 7 reseting procedures, taking out bar 8 closely cooperates all the time with plunger 7, and a circle button line is arranged in the body 10, make and take out bar 8 and can not move up simultaneously with plunger, thereby make hollow plunger rod 4 and hollow plunger 7 and take out the space enlargement that bar 8 terminations form and form negative pressure state, make and be positioned near the nozzle exit, and even the small volume of solution of nozzle exit outside is drawn back in the distributor, prevent to form dropping liquid and pollute dispenser container at the nozzle exit end, has also avoided solution using or contaminated during storage simultaneously.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection of the present utility model.
