Description

Water bath automatic drainage structure

technical field

The invention relates to an automatic water inlet and drain structure for a water bath, in particular to an automatic water inlet and drain structure for a tumor heat perfusion therapy instrument.

Background technique

Existing water baths generally add water to the water bath manually, and stop adding water when the water in the water bath reaches a sufficient water level; when draining water, the water in the tank is manually discharged or the water in the tank is discharged by using a pumping tool. Time-consuming, labor-intensive, and can spill the water bath if you're not careful.

Contents of the invention

The technical problem to be solved by the present invention is to provide an automatic water inlet and drain structure for a water bath for a tumor heat perfusion therapy instrument.

In order to solve the above technical problems, the present invention provides an automatic water inlet and drain structure of a water bath, which includes a water bath tank body, a liquid level sensor in the tank body, a first pipeline connected to the bottom of the tank body, and the first pipeline runs from top to bottom The first solenoid valve, one-way valve and self-priming pump are installed in sequence, the second pipeline is connected to the first pipeline through a tee, and the upper nozzle of the second pipeline is located between the first solenoid valve and the one-way valve. The lower nozzle of the second pipeline is located at the lower end of the self-priming pump, and a second electromagnetic valve is installed on the second pipeline, and the liquid level sensor, the first electromagnetic valve, the self-priming pump and the second electromagnetic valve are connected with the computer.

When the amount of water in the water bath is appropriate and there is no need for water intake or drainage, the first solenoid valve, self-priming pump and second solenoid valve are all closed; when the water level in the water bath is too low, the liquid level sensor sends a signal to Computer, the computer controls to open the first solenoid valve and the self-priming pump, so that the water enters the water bath through the first pipeline; when the water level in the water bath is too high and needs to be drained, the liquid level sensor also sends a signal to the computer, and the computer controls the opening The first solenoid valve and the second solenoid valve make the water in the water bath be discharged by gravity.

The beneficial effects of the present invention are that no matter water intake or drainage can be automated, no manual operation is required, labor is saved, and the phenomenon of too much or too little water in the water bath is avoided, which is convenient and fast.
