Abstract

A solar water heater with an overflowing-prevention device comprises a water tank and a heat-collection pipe, wherein the water tank is communicated with an upper water pipe and a lower water pipe in a sealed mode, a vertical barrel is fixedly connected inside the water tank, a wall of the vertical barrel is provided with a water-passing hole, the upper end of the vertical barrel is connected with an upper cover, the upper cover is located outside the water tank, a plugging device is fixedly connected inside the vertical barrel, a hollow cavity with a tapered part is arranged in the middle of the plugging device, a wall of the hollow cavity is provided with a water inlet which is communicated with the upper water pipe in a sealed mode, a tapered sealing plug is arranged in the hollow cavity of the plugging device, the upper end of the tapered sealing plug is fixedly connected with a pull rod which penetrates out of the upper end of the hollow cavity of the plugging device, the pull rod is movably connected with the plugging device, and the upper end of the pull rod is fixedly connected with a floater. When the water tank of the solar water heater is filled with water, the floater drives the tapered sealing plug to rise and to automatically plug the water inlet, so that overflowing is effectively prevented. The solar water heater with the overflowing-prevention device effectively achieves the overflowing-prevention function by utilizing a mechanical structure, thereby not only saving water resources, but also saving electricity.

Description

Solar water heater with anti-overflow device of water

Technical field

The utility model relates to a kind of solar water heater, relates in particular to a kind of solar water heater with anti-overflow device of water.

Background technology

At present the solar water heater that uses of people have with overflow pipe, what have has installed the magnetic valve of anti-overflow for using water wisely, but complex structure must consume electric energy.

The utility model content

The utility model provides a kind of solar water heater with anti-overflow device of water of energy savings for deficiency.

The technical scheme that the utility model solves the problems of the technologies described above is as follows:

A kind of solar water heater with anti-overflow device of water, comprise water tank and thermal-collecting tube, airtight upper hose and the downcomer of being communicated with on the water tank, it is characterized in that, be fixedly connected with vertical bucket in the water tank, have the limbers on the wall of vertical bucket, vertical bucket upper end is connected with loam cake, loam cake is positioned at outside the water tank, be fixedly connected with blanking plug in the vertical bucket, with the cavity of taper, have water inlet on the wall of this cavity in the middle of the blanking plug, water inlet communicates with upper hose is airtight, be provided with the taper blocking in the cavity of blanking plug, taper blocking upper end is fixedly connected with pull bar, and pull bar passes from the cavity upper end of blanking plug, pull bar and blanking plug are for being flexibly connected, and the pull bar upper end is fixedly connected with float.

After the water in the water tank in the utility model was filled, float drove the rising of taper blocking and automatically water inlet is blocked, and prevents that effectively spilling water, the utility model from utilizing frame for movement effectively to realize the anti-overflow function, has both saved water resource, has saved again electric energy.
