Abstract
The utility model relates to a vacuum flask switch. A valve body is arranged in the vacuum flask switch; a switching mechanism for controlling the valve body is arranged in a shell. The valve body and a sealed ring thereof can seal a water inlet end of the shell; a switching button of the switching mechanism can oppress a valve rod and the valve body to move from top to bottom. An opening for an inserted end of a sliding key to be inserted is arranged in the switching button; the upper part of the sliding key is higher than an upper cover body; a sliding key spring is arranged between the sliding key and the upper cover body. A water outlet part of the vacuum flask switch is provided with a mouth cover for sealing the water outlet; the mouth cover can rotate around a rotating shaft thereof. A gap for the other end of the mouth cover to be inserted is arranged in the switching button; a restoring spring of the switching button is arranged between the switching button and the shell. After water is poured, the sliding key is pushed, and the switching button is ejected under the action of the restoring spring; the valve body closes a water outlet passage, and simultaneously drives the mouth cover to close; thus, the water outlet passage is free from the pollution of dust.
Description
Technical field:
The utility model relates to a kind of vacuum flask switch.
Background technology:
At present, various vacuum flask constructions of switch are numerous, just disclose a kind of " vacuum flask switch " for No. 00218491.5 as Chinese patent.In this technical scheme, exhalant canal opens and closes by changing the cock body height and realizes, is finished by the angle core mechanism and change the cock body height.It has the following disadvantages:
1, do not seal owing to exhalant canal, easily by contamination by dust.
2, because the angle core can block in use, cause vacuum flask switch cisco unity malfunction; And the angle core is wearing and tearing easily in use, cause the vacuum flask switch undesirable service life.
Summary of the invention:
At above deficiency, the inventor has proposed a kind of reliable operation, long vacuum flask switch of easy to use, life-span.The utility model is achieved through the following technical solutions:
A kind of vacuum flask switch is provided with valve body in the vacuum flask switch, is provided with the switching mechanism of application valve body in the housing.Valve body and sealing ring thereof can be with the water inlet end sealings of housing, the shift knob of switching mechanism can oppress valve rod and valve body moves up and down, be provided with in the shift knob and can hold the opening that the feather key insertion end is inserted, feather key top exceeds upper cover body, is provided with the feather key spring between feather key and upper cover body; The delivery port place of vacuum flask switch is provided with the mouth lid that is used to seal delivery port, and the mouth lid can rotate around its rotating shaft, is provided with in the shift knob to hold the breach that the mouth lid other end inserts, and is provided with the shift knob back-moving spring between shift knob and housing.
The course of work of the present utility model is as follows: press down shift knob, button compressing valve rod moves down, button drives mouth lid insertion end simultaneously and moves, the mouth lid is rotated around its rotating shaft, the mouth lid is opened automatically, and when button put in place, feather key was under the effect of its spring, opening on the button that the insertion end of feather key is inserted is realized the button location.At this moment, the valve body of housing water inlet end is opened, and just can carry out the pouring operation.After pouring is finished, promote feather key, shift knob ejects under its action of reset spring, makes valve body sealing exhalant canal, and drives mouth simultaneously and cover, and makes exhalant canal exempt from contamination by dust.
Because the utility model saved angle core mechanism of the prior art, make the utility model reliable operation, long service life.
In the utility model, be provided with the retaining plug in the described shift knob, the retaining plug can be oppressed the valve rod top moves valve rod and valve body, and the shift knob below is provided with collar, and the shift knob back-moving spring is located between housing and collar.Adopt said structure, make the utility model rational in infrastructure, be convenient to make.
In the utility model, described valve rod is provided with sealing ring.It can prevent that sealing drains in the housing inner chamber.
In the utility model, described vacuum flask switch external is provided with outer cover, and the outer cover inner face is provided with the inclined-plane that matches with feather key.Press down outer cover, feather key can be oppressed in the inclined-plane of outer cover inner face, makes push-button reset, guarantees that water can not leak outside.
Description of drawings:
Generalized section when Fig. 1 is the sealing of the utility model embodiment 1 exhalant canal.
Fig. 2 is the utility model embodiment 1 exhalant canal structural representation when opening.
Fig. 3 is that the utility model is installed on back generalized section on the thermos cup.
The specific embodiment:
In conjunction with Fig. 1, shown in Figure 2: be provided with valve body 1 in the vacuum flask switch of present embodiment, be provided with the switching mechanism of application valve body in the housing 3.Valve body and sealing ring 2 thereof can be with the water inlet end sealings of housing 3, and the shift knob 4 of switching mechanism can be oppressed valve rod 5 and valve body 1 upper and lower moving, and valve rod is provided with sealing ring 6.Be provided with in the shift knob 4 and can hold the opening 8 that feather key 7 insertion ends are inserted, feather key top exceeds upper cover body 9, is provided with feather key spring 10 between feather key 7 and upper cover body.The delivery port place 11 of vacuum flask switch is provided with the mouth lid 12 that is used to seal delivery port, and the mouth lid can rotate around its rotating shaft 13, is provided with in the shift knob and can holds the breach 15 that the mouth lid other end 14 inserts, and is provided with shift knob back-moving spring 16 between shift knob and housing.
Be provided with retaining plug 17 in the shift knob, the retaining plug can be oppressed the valve rod top moves valve rod 5 and valve body 1, and the shift knob below is provided with collar 18, and shift knob back-moving spring 16 is located at 18 of housing 3 and collars.
As shown in Figure 3: vacuum flask switch external of the present utility model is provided with outer cover 19, and the outer cover inner face is provided with the inclined-plane 20 that matches with feather key.Press down outer cover, feather key can be oppressed in the inclined-plane of outer cover inner face, makes push-button reset, guarantees that water can not leak outside.
The utility model vacuum flask switch is after pouring is finished, and the mouth lid can seal exhalant canal automatically, makes exhalant canal exempt from contamination by dust.Saved angle core mechanism of the prior art, more reliable, the longer service life of vacuum flask switch work.Simultaneously, the inclined-plane of outer cover inner face makes the vacuum flask switch have auto-lock function, guarantees that water can not leak outside.
