DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The present utility model will be further described below with reference to the accompanying drawings.

[0023] A rapid heat pump pump head, which is a rapid hot water pump accessory used for circulating water in a household hot water pipeline. An inlet 1, an outlet 2 and a return port 3 are connected to the pump head. Among them, the inlet is connected to the cold water pipe 11 in the household water pipeline, the outlet 2 is connected to the water heater 12 through a pipeline, and the return port 3 is connected to the return water pipeline 13 in the household water pipeline. Cold water flows into the pump head through the inlet 1, and the pump body on the pump head transports the cold water into the water heater 12. After the cold water is heated by the water heater, it is transported into the hot water pipeline 14. Both ends of the return water pipeline 13 are connected to the return port 3 and the hot water pipeline 14 respectively, so as to return the cold water in the hot water pipe to the circulation pump, facilitating the recycling of the cold water in the hot water pipe and reducing water resource waste; A water pump main body 16 is installed at the end of the pump head to drive the liquid flow in the pump head.

[0024] A strip-shaped connecting part 15 is provided in the middle of the pump head. The strip-shaped connecting part is of a hollow structure, and both ends of the strip-shaped connecting part 15 extend to both sides of the pump head. An inlet channel 4 is formed in the strip-shaped connecting part 15. The inlet 1 and the return port 3 are respectively communicated with the inlet channel 4, facilitating the inflow of cold water or return water into the pump head.

[0025] As a preferred implementation manner, the return port 3 is L-shaped, so that the return port 3 is connected to the side of the strip-shaped connecting part 15. The inlet 1 is a straight pipe and is connected to the bottom of the strip-shaped connecting part 15. The outlet 2 is arranged on the side wall of the pump head. The inlets 1, outlets 2 and return ports 3 are in the same orientation, effectively saving the installation space of the water pump and reducing the installation difficulty.

[0026] A return water check valve 5 is provided in the return port 3, so that the liquid flow direction in the return port 3 is from the return water pipeline 13 to the pump head, preventing cold water from directly flowing into the return port 3 and ensuring the water flow enters the household water pipeline.

[0027] An electromagnetic valve 6 is provided on the return port 3. The electromagnetic valve 6 is located between the return water check valve 5 and the pump head. The on-off of the return port 3 is controlled by the electromagnetic valve 6 to cut off the return port 3, so that after the water pump pressurizes the indoor pipeline, the circulation flow path is cut off to ensure that the water pressure does not leak.

[0028] An inlet check valve 7 is provided in the inlet 1, so that the liquid in the inlet 1 flows from the cold water pipe 11 to the pump head. A Hall sensor 8 is provided in the inlet 1. The Hall sensor 8 is arranged inside the inlet check valve 7, that is, the Hall sensor is located between the inlet channel 4 and the inlet check valve 7. After the pump body works, the water pressure in the household water pipeline increases. When the water pressure in the household water pipeline is greater than the water pressure in the public pipeline, causing the phenomenon of water flow back, the inlet check valve 7 is used to prevent the water flow back and avoid the Hall sensor 8 being triggered by the water flow back and misstarting.

[0029] A connecting plate 9 is also provided on the pump head. The connecting plate 9 is respectively connected to the water inlet 1, the water outlet 2, and the water return port 3. An installation through hole 10 is provided on the connecting plate 9, and the connecting plate 9 is installed at the position to be installed through the installation through hole 10, so as to fix the pump head and improve the installation convenience of the circulation pump.

[0030] There is a temperature sensor 16 on the water outlet 2. The temperature sensor 16 is used to detect the water temperature change in the water outlet 2.

[0031] In this embodiment, in order to facilitate the production of the speed heat pump pump head, the water outlet 2 is arranged in the middle of the speed heat pump pump head, and the water inlet 1 and the water return port 3 are respectively arranged on both sides of the speed heat pump pump head, so that the strip-shaped connecting portion 15 is arranged along the width direction of the speed heat pump pump head, thereby facilitating the parting of the speed heat pump pump head during casting and improving the casting convenience.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0033] Although more terms corresponding to the reference numerals in the drawings are used herein, the possibility of using other terms is not excluded; these terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
