[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] See Figures 1-8 This heating pump includes a pump body 1, a pump housing 2 mounted on the pump body 1, and a heating element 3. An installation cavity 4 is provided on the outer side of the pump housing 2. An installation part is provided between the heating element 3 and the pump housing 2. The heating element 3 is mounted on the installation cavity 4 through the installation part.

[0026] The mounting section includes several mounting buckles 5 arranged in a ring on the heating tube 3 and several clips 6 arranged in a ring on the pump housing 2. The mounting buckles 5 are rotated and pressed onto the clips 6 so that the heating tube 3 is mounted on the mounting cavity 4.

[0027] A flange ring 7 is provided at the bottom of the mounting cavity 4, and several protective ribs 8 are arranged in a ring on the heating tube 3. The protective ribs 8 are locked on the outside of the flange ring 7 to prevent the heating tube 3 from tilting and causing poor sealing.

[0028] The mounting buckle 5 and the protective rib 8 are spaced apart from each other, and the buckle 6 extends to the outside of the flange ring 7.

[0029] A sealing groove 9 is provided on the inner side of the flange ring 7, and a sealing ring 10 is provided in the sealing groove 9. A pressing edge 11 is provided on one end of the heating tube 3. The sealing ring 10 is pressed between the pressing edge 11 and the flange ring 7. The sealing ring 10 is used to seal the gap between the pump housing 2 and the heating tube 3.

[0030] A protective cover 12 extends from the outer side of the pump housing 2, and the protective cover 12 surrounds the outer periphery of the heating tube 3. The mounting cavity 4 is located inside the protective cover 12. The protective cover 12 isolates the heating tube 3 from the surrounding objects of the pump housing 2 to prevent the surrounding objects from touching the heating tube 3.

[0031] The heating element 3 includes a shell 16, a flow pipe 13 for water to pass through, and a heating wire 14 for heating the water. The shell 16 is sleeved on the outside of the flow pipe 13, and the heating wire 14 is integrally set on the shell 16. The heating wire 14 and the shell 16 are die-cast together. The die-casting process is used to fuse the heating wire 14 and the shell 16 into one seamless unit with a compact structure and high heat utilization rate.

[0032] A thermostat 15 is provided on the outside of the flow pipe 13 for detecting water flow temperature and providing overheat disconnection protection. The thermostat 15 is connected to the heating wire 14. When the thermostat 15 detects that the water temperature in the flow pipe 13 is higher than the set value, the thermostat 15 disconnects, thereby stopping the heating wire 14 from working. Two thermostats 15 are provided.

[0033] An impeller 17 is mounted on the pump body 1, and an inner cavity 18 extends from the inner side of the pump casing 2. The impeller 17 is located within the inner cavity 18, and an outlet 19 is provided on the side of the pump casing 2. The flow pipe 13, the inner cavity 18, and the outlet 19 are connected in sequence. Figure 3 As shown by the arrow, water enters through the flow pipe 13, the heating wire 14 operates, the water is heated, and the heated water enters the inner cavity 18, is driven by the impeller 17, and is discharged from the outlet 19 after being pressurized.

[0034] The flow tube 13 is made of stainless steel, and the tube shell 16 is made of cast aluminum. The stainless steel material of the flow tube 13 isolates water from the cast aluminum (tube shell 16) and prevents hot water from corroding the cast aluminum.

[0035] When installing this heat pump, first install the sealing ring 10 in the sealing groove 9 of the pump housing 2, then clip the protective rib 8 of the heating tube 3 onto the outside of the flange ring 7 of the pump housing 2, and then press and rotate the heating tube 3 so that the mounting buckle 5 on the heating tube 3 is pressed onto the buckle 6 of the pump housing 2, and the installation is completed.
