Specific embodiment
It is to reach the technological means and effect that predetermined purpose of utility model taken for the utility model is expanded on further, with
Lower combination attached drawing and preferred embodiment, to according to the utility model proposes cleaning pump specific embodiment and operation principle into
Row is described in detail.
As shown in Figure 1, Figure 3, the cleaning pump that the utility model embodiment is provided, including：It is mounting base 1, diaphragm 2, unidirectional
Valve seat 3, check valve 5, check valve pressing plate 4.Check valve pressing plate 4, one-way valve seat 3, diaphragm 2,1 four sequence of mounting base closely connect
It connects, is closely connected using removable mode in the present embodiment, between this.
The lower part of mounting base 1 is provided with power plant connector 8, is provided between power plant and power plant connector
Solenoid valve.The power plant selected in the present embodiment includes vacuum generator and main ink road, and power plant connector 8 is sent out with vacuum
Solenoid valve is both provided between raw device, between power plant connector and main ink road.
The top of mounting base 1 offers the groove of bowl structure, is set between the slot bottom of groove and power plant connector 8
There is through-hole 9.
In the present embodiment, on 5 valve outer wall of check valve there is boss-shaped structure 13, first seal is provided on spool 10
11。
First through hole, the second through-hole of through diaphragm 2, one-way valve seat 3 are offered on check valve pressing plate 4 to one-way valve seat 3
With at the first through hole at 4 connecting position of check valve pressing plate, the second through hole, be both provided with to convex on check valve valve outer wall
The check valve valve body position limiting structure that mesa-shaped structure 13 is limited.
It is both provided with check valve 5 in first through hole and the second through-hole, the boss-shaped structure 13 on the valve outer wall of check valve 5
Be set in check valve valve body position limiting structure by second seal 12 setting up and down, the check valve 5 in first through hole it is close
It is towards 2 direction of diaphragm to seal the sealing direction that direction is the check valve 5 in 2 direction of diaphragm, the second through-hole.
The first pipeline connecting with the export pipeline of detergent container is provided on check valve pressing plate 4 at first through hole to connect
First 6, the second pipe joint 7 being connect with the ink road of nozzle to be cleaned is provided on check valve pressing plate in the second through hole, is treated clear
It washes between the ink road of nozzle and the second pipe joint 7 and is provided with second solenoid valve.
During work, as shown in Fig. 2, the present apparatus is laterallyd secure, make the horizontal position of first through hole compared with the water of the second through-hole
Prosposition puts height, more cleaning agents can be used when the purpose set in this way is cleaning, cleaning is more thorough, and effect is more preferable.
When taking out cleaning agent, the solenoid valve between power plant connector 8 and vacuum generator is opened, under suction function, unidirectionally
The spring of valve 5 is compressed, and spool 10 is moved to 2 direction of diaphragm, and the sealing ring 11 on spool 10 leaves check valve valve body, cleaning agent
