[0007] Furthermore, a plurality of connecting seats 1 connected to the interior of the inner liquid outlet pipe are provided on the circumferential side surface of the inner liquid inlet pipe, a plurality of connecting seats 2 connected to the interior of the inner liquid inlet pipe are provided on the circumferential side surface of the inner liquid outlet pipe, one port of the connecting tube 2 is mounted on the connecting seat 1, and the other port of the connecting tube 2 is mounted in the connecting seat 2, an inner spiral blade is provided on the inner side of the connecting tube 2, and an outer spiral blade is provided on the outer side of the connecting tube 2.

[0008] Furthermore, the end face of the connecting seat 1 is a corrugated surface, the corrugated surface contacts the end of the outer spiral blade, and one end of the connecting pipe 2 close to the connecting seat 2 is sleeved with a limiting ring, and a spring is provided between the limiting ring and the connecting seat 2.

[0009] Furthermore, both ends of the outgoing liquid pipe are provided with a dirt storage box, the dirt storage box is located at the bottom of the outgoing liquid pipe, a cleaning port communicating with the interior is opened on the outer surface of the dirt storage box, and a valve is sealed on the cleaning port.

[0010] Furthermore, a swinging part is sleeved on the outer side of the inner liquid inlet pipe, and the flowing water drives the swinging part to swing.

[0011] Furthermore, the swinging part includes a clamping ring and a corrugated plate, and a plurality of clamping rings are clamped on a plurality of the inner liquid inlet pipes. An installation groove is opened on the same side of the clamping rings, and a plurality of connecting rods extend from the corrugated plate. The connecting rods correspond to the installation grooves one by one, and the corrugated plate is connected to the installation grooves through the connecting rods and is installed on the clamping rings.

[0012] A method for controlling a heating system comprises the following steps:

[0013] Step 1: After opening the control valve, the hot water in the heater enters the inner liquid inlet pipe through the pump body installed on the connecting pipe, and the water flows into the inner liquid outlet pipe through the connecting pipe 2 under the action of pressure;

[0014] Step 2: The hot water is returned to the heater for further heating. The returned hot water has residual temperature, which effectively reduces the temperature that the heater needs to increase and reduces energy loss.

[0015] Step 2: When the hot water passes through the inner liquid outlet pipe, the inner liquid inlet pipe and the connecting pipe 2, the cold water in the heat dissipation pipe passes through the outer liquid inlet pipe, the outer liquid outlet pipe and the connecting pipe 1 under the action of the pump body, thereby completing the heat exchange, and the heat is diffused into the room through the fins installed on the outer side of the heat dissipation pipe or the connecting pipe 1, thereby achieving heating.

[0016] The present invention has the following beneficial effects:

[0017] 1. The hot water in the heater of the present invention enters the inner liquid inlet pipe through the pump body installed on the connecting pipe. Under the action of pressure, the water flows into the inner liquid outlet pipe through the connecting pipe 2 and flows back to the heater for further heating. The refluxed hot water has residual temperature, which effectively reduces the temperature that the heater needs to increase and reduces energy loss.

[0018] 2. When the hot water of the present invention passes through the inner liquid outlet pipe, the inner liquid inlet pipe and the connecting pipe 2, the cold water in the heat dissipation pipe passes through the outer liquid inlet pipe, the outer liquid outlet pipe and the connecting pipe 1 under the action of the pump body, thereby completing the heat exchange, and the heat is diffused into the room through the fins installed on the outside of the heat dissipation pipe or the connecting pipe 1, thereby realizing heating.

[0019] 3. In the present invention, inner and outer sides of the connecting pipe 2 are respectively provided with inner and outer spiral blades. Hot water passing through the inner spiral blades or cold water passing through the outer spiral blades both drive the connecting pipe 2 to rotate. The inner and outer spiral blades have opposite rotation directions, thereby pushing the hot water inside the connecting pipe 2 or the cold water outside the connecting pipe 2, which can reduce the installation of power components.

[0020] 4. The end of the outer spiral blade of the present invention moves along the corrugated surface of the connecting seat 1, so that the rotating connecting pipe 2 can vibrate up and down under the push of the spring, which is convenient for scraping off the attachments on the inside of the connecting pipe 1 and making the attachments fall into the outgoing liquid pipe. At the same time, the flowing water electric swing part swings, which is convenient for pushing the sediment inside the outgoing liquid pipe to the dirt storage boxes provided on both sides for collection.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
