Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Fig. 1 shows the structural representation of automatic regulation and control device of liquid level according to the preferred embodiment of the invention, and Fig. 2 shows a kind of structural representation of the employed conduit of automatic regulation and control device of liquid level according to the present invention.In conjunction with seeing figures.1.and.2, in this preferred embodiment, automatic regulation and control device of liquid level 100 comprises: fluid infusion container 10, be used for the splendid attire working fluid, and it has plug 13 sealed opening 11; Conduit 30 has the insertion end 31 of the plug 13 that is suitable for puncturing, and this insertion end 31 is formed with liquid guide flow hole 35; Work container 40, its inner splendid attire working fluid; And support 20, being used for conduit 30 is supported on Work container 40 straight up, this support is at the seat 25 that forms support fluid infusion container 10 on every side of the insertion end 31 of conduit 30.
Wherein, have guide pin bushing 21 that is sheathed on outside the conduit 30 and the adjustment bolt 23 that is used for fastening conduit 30 that is arranged on the guide pin bushing 21 on the support 20.This design is very helpful, by adjusting the height of conduit 30, the height of liquid level in the adjustable full employment container 40.
It is liquid-consumed that the working fluid of above-mentioned fluid infusion container 10 splendid attires is used for automatic compensation work container 40, after the liquid in the fluid infusion container 10 uses, fluid infusion container 10 is pulled up from conduit 30, fluid infusion container 10 with the splendid attire working fluid is pressed into conduit 30 again, make the insertion end 31 of conduit 30 pierce through plug 13, and fluid infusion container 10 supported or be positioned in the seat 25 on the support 20.
By above description as can be seen, automatic regulation and control device of liquid level of the present invention has simple in structure simultaneously and changes fluid infusion container advantage easily, when changing, be not easy leakage during the fluid infusion container, the application number that being adapted at the applicant provides is to use in 200910098952.0 the automatic soaking type humidifying device, and its full content is incorporated into that this is for reference.Work container among the present invention correspondingly is the lower house of automatic soaking type humidifying device, and wherein, support of the present invention can be by last hood-shaped one-tenth, also can constitute separately, it is inboard that the fluid infusion container can be arranged on cover, also can be arranged on the cover outside, can come to determine layout as required.
Fig. 3 shows the A-A sectional view of conduit shown in Figure 2.As shown in the figure, conduit 30 is an improved plastics structural shape, can make by injection molding process, and the conical wall of its insertion end 31 is provided with thin-wall regions 33, this thin-wall regions 33 is used to form liquid guide flow hole 35, for example can be by piercing through or mode such as through welding forms liquid guide flow hole 35.This liquid guide flow hole 35 can be extended on the whole zone of thin-wall regions, also can extend on the subregion, so, the pore size in liquid guide flow hole 35 scene is as required offered, liquid guide flow hole 35 its flow differences in different apertures so play the adjustable effect of flow.
The inside diameter D of conduit 30 is preferably 8～25mm, to avoid causing capillarity can not replenish working fluid because of internal diameter is too small, avoids the excessive damage that causes plug of inside diameter D of conduit 30 simultaneously.The inside diameter D of conduit 30 more preferably is 12～15mm.
It is conical that above-mentioned insertion end 31 is, and also can be oblate taper unlikely damage conveniently to pierce through plug 13.
Fig. 4 shows the synoptic diagram of the another kind of structure of the employed conduit of automatic regulation and control device of liquid level according to the present invention.As shown in Figure 4, the conical wall of conduit 30 is provided with two thin- wall regions 33,37, offers liquid guide flow hole 35 on the thin-wall regions 33 wherein.By two or more thin-wall regions are set, conveniently optionally offer liquid guide flow hole 35 according to flow.Liquid guide flow hole 35 can form by the form of removing whole thin-wall regions at this moment.
In addition, for making things convenient for the length of fit between restricted conduit 30 and the fluid infusion container, be provided with limited step 39 on conduit 30, this limited step 39 can be one-body molded with conduit, also can divide the assembling of body formed back to form, and this limited step 39 can also be supported on the guide pin bushing 21.
Fig. 5 shows another structural representation of the employed conduit of automatic regulation and control device of liquid level according to the present invention.As shown in the figure, conduit 30 is 90 degree bend pipes, so, the adjustable opening of reorganizing and bringing up liquid container 10 to full strength direction is set, arrange down and be not limited to opening, so can make the shaped design variation of fluid infusion container, satisfy the space layout requirement of fluid infusion container.
Fig. 6 shows the vertical view of the plug that matches with conduit.As shown in Figure 6, plug 13 has center weakness zone 133 and is the radial weak area 131 that extends radially outwardly, and the outside diameter d of wherein radial weak area 131 is slightly smaller than the external diameter of conduit.So, when conduit 30 inserts plug, pierce through center weakness zone 133 at first, during insertion, radial weak area 131 is torn to root, because the outside diameter d of radial weak area can encase conduit tightly less than the external diameter of conduit 30, and unlikely leakage, it is less relatively to make that simultaneously conduit inserts resistance.
By above description as can be seen,, have the purpose of easy replacing fluid infusion container, avoid simultaneously because of operating former thereby leakage according to automatic regulation and control device of liquid level of the present invention.
Be the preferred embodiments of the present invention only below, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
