Description
Technical field
The present invention relates to a kind of by the ejection of M/C with high viscosity liquids such as realization shampoos, the perhaps ejection of low viscosity liquid such as toner and the liquid discharge device as the pump formula of spraying, particularly, relate to a kind of can be definitely from open circuited valve seal body of valve seat and the initial sealing body that this device remained on unused state.
Background technology
Based on the liquid discharge device of pumping have under before use the situations such as carrying, for preventing that liquid in the container is from several measures of shower nozzle mistake ejection.
Prevailing in these measures is that shower nozzle is maintained static.This fixing means is divided into substantially and shower nozzle is forced down nethermost lower dead point position working fastening and these 2 kinds of the first dead center that does not force down (first dead center) position working fastenings.
Wherein, a kind of means in back in the upper dead center position working fastening, owing to will not remain on compressive state by built-in spring body (spring) in liquid discharge device, spring body can remain effectively, compare with preceding a kind of means in the lower dead point position working fastening, its effect more is subject to people's attention.
For this reason, developed method that shower nozzle is temporarily fixed at upper dead center position etc., this method is, the proof liquid discharge device is in the initial sealing of so-called unused state, be and be arranged at the piston periphery that is combined in the shower nozzle bottom (below, the initial sealing that will have function like this is called the initial sealing body) with surrounding shape.
As the 2nd measure that prevents that liquid from discharging, further developed a kind of the extension in recent years the valve seat that is positioned at internal piston has been set, form the valve seal body to interrupt the method that liquid is discharged at its peristome.
Be under the so-called unused state at liquid discharge device, the valve seal body is the state of closed valve seat peristome.
And, initially use when this device, as press down shower nozzle, by the decline of the piston of combination with it, the leading section that is arranged on the housing internal valve will push away on the valve seal body, the peristome of valve seal body dialysis valve seat, thus the liquid in the container can rise.
This situation is described with reference to the accompanying drawings.
Figure 11 illustrates the cutaway view that shower nozzle is moved down into the liquid discharge device in the past (being pumping in this example) under the lower dead point position state.
1 for filling the container of liquid L, and 2 for being installed in the lid of container 1 oral area, and 3 is the shower nozzle that can be installed with the mode of piston while up-and-down movement with relative this lid 2.
By up-and-down movement shower nozzle 3, the liquid L in the container 1 can be discharged.
4 for being installed in and covering on the 2 all-in-one-piece ring portions 9, and falling in sleeve in the container 1 down, 5 is with the lower junction integrator of shower nozzle 3 and with the piston of shower nozzle 3 up-and-down movements, 6 for applying the upwards spring of elastic force to piston 5,7 for being contained in the valve body in the piston 5, and 8 for being contained in the valve body in the sleeve 4.
Above valve body 8, be integrally formed into it from the upwardly extending leading section 8A of the front end of valve body 8.
In addition, in the extension of the inside of piston 5 valve seat 51 is being set.
Figure 12 is the enlarged drawing that the valve seal body of device under unused state, under the peristome state of closed valve seat is shown, and wherein, (A) is cutaway view, (B) is birds-eye view.
When Figure 13 brings into use for device is shown, piston 5 descends, push away under the effect on the leading section 8A of valve body 8, the enlarged drawing of the valve seal body under the peristome state of other part dialysis valve seats except that articulated section (ヒ Application ジ portion), wherein, (A) being cutaway view, (B) is birds-eye view.
So, valve seal body 51A becomes the state of the peristome 51B of closed valve seat 51 under device is in unused state.

In addition, the part of thinner wall section 51A1 forms heavy wall (articulated section 51A2), because this part 51A2 place intensity height, can dialysis, and valve seal body 51A is connected with valve seat 51.
Therefore, even for example, above-mentioned initial sealing body as long as the valve seal body is sealing the peristome of valve seat, can stop the liquid in the container to misprint out because of careless dialysis, when how many shower nozzles moves up and down.
But when pressing down shower nozzle 3 to lower dead point position, valve seal body 51A is pushed up from the below brute force by the leading section 8A of valve, and top power disconnects thinner wall section 51A1 on this, by articulated section 51A2, and upwards bending.
So, as Once you begin using this liquid discharge device, valve seal body 51A just can take off from valve seat 51.
In addition, because the flow direction of liquid L makes progress all the time, the valve seal body 51A of bending can not return to its original state (state of closed valve seat peristome).
, in liquid discharge device in the past, push the articulated section side of valve seal body on the leading section of valve to, thus, the valve seal body is the dialysis valve seat definitely, the phenomenon that exists liquid fully not discharge.
