Detailed description of the invention

Below preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature energy It is easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.

As shown in Figure 1 and Figure 2, a kind of disc pump, including the pump housing 1, drive shaft 2 and an annulus 3, this pump housing 1 is hollow Disc-shaped structure, this drive shaft 2 is connected with the center rotating of this pump housing 1,

As it is shown on figure 3, the side of this pump housing 1 is provided with feed tube 11 and a drain pipe 12, this feed tube 11 goes out with this Liquid pipe 12 is arranged parallel to and is arranged in the same side of this pump housing 1, is provided with a dividing plate 13 in this pump housing 1, this dividing plate 13 edge The radial arrangement of this pump housing 1, this dividing plate 13 is arranged between this feed tube 11 and drain pipe 12；

As shown in Figure 4, this annulus 3 is provided with a breach 31, inner side is provided with one " n " shape connecting rod 32, is somebody's turn to do " n " shape even The middle part of extension bar 32 is disposed with a shaft hole 33, and the two ends being somebody's turn to do " n " shape connecting rod 32 are connected with this annulus 3, should " n " shape connect The two ends of bar 32 are arranged in the both sides of this breach 31；

As it is shown in figure 5, the end of this drive shaft 2 is provided with a clutch disk 21, the center of this clutch disk 21 is driven with this Moving axis 2 is mutually connected vertically, and this connecting shaft 22 is mutually connected vertically with the edge of this clutch disk 21；

As in figure 2 it is shown, this connecting shaft 22 is rotationally connected with this shaft hole 33, it is somebody's turn to do " n " shape connecting rod 32 across this dividing plate 13 On, this breach 31 is stuck on this dividing plate 13 and bonded to each other with the surface of this dividing plate 13.

Along with the rotation of this drive shaft 2, this connecting shaft 22 is non-coaxial layout with this drive shaft, driving of this connecting shaft 22 Under Dong, the different parts being fitted in this pump housing 1 of the surface periodic of this annulus 3, this breach 31 slide on this dividing plate 13, should This liquid entered from feed tube 11 periodically can be pushed into this drain pipe 12 by annulus 3, reaches the effect of pump.Although dividing plate The pressure differential of 13 both sides liquid is relatively big, but owing to dividing plate 13 is stationary components, is therefore easier to fully seal, thus efficiency is relatively High.

As shown in Fig. 2, Fig. 5, Fig. 6, the both sides of this breach 31 are respectively disposed with a swing link 34, this swing link 34 and this circle Ring 3 is connected and is arranged in the inner side of this " n " shape connecting rod 32, this swing link 34 opening towards disposed inboard, this swing link 34 Inside being disposed with an arch sealing block 4, the cross section of this arch sealing block 4 is arch, includes that a circular arc sealing surface 41 and is flat close Front cover 42, this circular arc sealing surface 41 is slidably connected with this swing link 34, and this smooth seal face 42 is slidably connected with this dividing plate 13, this arch Two end faces of shape sealing block 4 are slidably connected with the inner surface of this pump housing 1.This structure can increase this breach 31 and this dividing plate Sealing area between 13, improves sealing effectiveness, improves the reliability of this disc pump；And can after this this arch sealing block 4 is set To avoid the annulus 3 that replacement cost is higher, after arch sealing block 4 is worn, replacement cost is relatively low.

It is only more than the mentality of designing of some embodiments of the present utility model, in the case of system allows, this reality The most external more functional module can be expanded to novel, thus extend its function to greatest extent.

The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit to In this, any change expected without creative work or replacement, all should contain within protection domain of the present utility model. Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims are limited.
