Wherein: 1. a body; 2. a reservoir; 3. a magnetic pump; 4. a transfusion pipeline; 5. a liquid outlet end; 6. a connecting end; 7. a flood protection pipeline; 8. an air inlet; 9. a one-way valve; 10. a connecting pipe; 11. a left side tube; 12. a right side tube; 13. an interface.
Detailed Description
The invention will be further described with reference to the following drawings and examples:
the first embodiment is as follows: referring to fig. 1, a liquid conveying device includes a machine body 1, a reservoir 2, a magnetic pump 3 and a liquid conveying pipeline 4, wherein the magnetic pump is installed on the machine body, a liquid inlet of the magnetic pump is connected with the machine body, a connecting end of the liquid conveying pipeline is connected with a liquid outlet of the magnetic pump, a liquid outlet end 5 of the liquid conveying pipeline 4 is inserted into the reservoir 2, a bottom of the reservoir is arranged below a bottom surface of the machine body, the magnetic pump 3 is installed at the top of the machine body, a vertical space is arranged between a connecting end 6 of the liquid conveying pipeline 4 and a liquid outlet end of the liquid conveying pipeline, and the liquid outlet end of the liquid conveying pipeline is arranged below a side of the connecting end of the liquid conveying pipeline; the device is also provided with a flood control pipeline 7, the top of the flood control pipeline is connected with the middle part of the infusion pipeline, the bottom of the flood control pipeline is arranged right below the infusion pipeline, the bottom of the flood control pipeline is provided with an air inlet 8, the air inlet is communicated with the infusion pipeline through the flood control pipeline, the bottom of the flood control pipeline is provided with a one-way valve 9, and the one-way valve is arranged close to the air inlet; the air inlet is arranged between the bottom surface of the connecting end of the infusion pipeline and the bottom surface of the liquid outlet end.
Referring to fig. 1, the infusion pipeline includes a connecting pipe 10, a left pipe 11 and a right pipe 12 which are communicated with each other, the left side of the connecting pipe is connected with the top of the left tank, the right side of the connecting pipe is connected with the top of the right pipe, the left pipe and the right pipe are arranged in parallel, the connecting pipe is perpendicular to the left pipe and the right pipe, the bottom of the left pipe is a connecting end, and the bottom of the right pipe is a liquid outlet end.
The length of the left side pipe is less than the length of the right side pipe.
The flood control pipeline is parallel to left side pipe and right side pipe setting, the length of flood control pipeline is greater than the length of left side pipe, the length of flood control pipeline is less than the length of right side pipe, be equipped with a interface 13 on the bottom outer fringe face of connecting pipe, the top of flood control pipeline with the interface links to each other.
