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.
Advantage with the disc pump of elastic reset bar of the present utility model is: the isolation with two release link compositions is entered
Liquid mouth and the isolation structure of liquid outlet, the pressure reduction of each release link both sides is less, and sealing effectiveness is preferable, and capacity usage ratio is higher,
Pressure is relatively big, and lift is the biggest.
As it is shown in figure 1, a kind of disc pump with elastic reset bar, including the pump housing 1, driving dish 2 and a drive shaft
3, this pump housing 1 is the disc-shaped structure of hollow, side is provided with a feed tube 11, opposite side is provided with a drain pipe 12, and this drives
Moving axis 3 passes the center of this pump housing 1 and is rotationally connected with this pump housing 1, and this driving dish 2 is mutually perpendicular to this drive shaft 3 and fixing
Connecting, this driving dish 2 is circular configuration, and this drive shaft 3 deviates the center of circle of this driving dish 2 and arranges, should be with elastic reset bar
Disc pump also includes two release links 4, in this release link 4 is arranged in this pump housing 1 and one end is hinged with the edge of this pump housing 1, this
Release link 4 is connected also by reed with this pump housing 1, and the other end of this release link 4 is provided with a sealing block 41, this sealing block 41
Being fitted on the side of this driving dish 2 and be slidably connected with it, these two release links 4 are arranged in the left and right of this driving dish 2
Both sides.This reed can drive this release link 4 to swing the side enabling its end to be close to this driving dish 2 all the time, thus plays
Sealing function；Owing to this disc pump with elastic reset bar being isolated the isolating device of this feed tube 11 and this drain pipe 12 it is
The two-stage isolation structure being made up of two release links 4, the pressure reduction of the most each release link 4 both sides is less, feed tube 11 with go out liquid
The most farther out, therefore sealing effectiveness is preferable for distance between pipe 12, is conducive to improving capacity usage ratio and pressure, makes this band flexible
The disk pump lift of release link is bigger.
As shown in Figure 1 and Figure 2, this release link 4 is hinged with this sealing block 41.It is provided with a circular arc on this sealing block 41 to seal
Face 411, the radius of this circular arc sealing surface 411 is equal to the radius of this driving dish 2, and this circular arc sealing surface 411 is fitted in this driving dish 2
Side on and be slidably connected with it.This structure makes this circular arc sealing surface 411 can be close to the side of this driving dish all the time, because of
And sealing effectiveness is preferable.
As in figure 2 it is shown, one end of this release link 4 is provided with circular projection 42, as it is shown in figure 1, be provided with inside this pump housing 1
Two circular grooves 13, in this circle projection 42 is arranged in this circular groove 13 and with this coaxial cloth of circular groove 13
Putting, this circle projection 42 is slidably connected with the inner surface of this circular groove 13.It is multiple from this that this structure desirably prevents fluid
The tail end of position bar 4 is revealed, and improves the sealing effectiveness of this release link 4 further.
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.
