Description

Technical Field

[0001] This utility model relates to a water pump specifically designed for use in a water-heated blanket main unit. Background Technology

[0002] Water-heated blankets heat water to a set temperature via an external water-heated blanket unit. The hot water is then pumped to the inlet of a plastic water pipe inside the blanket. The water from the outlet of the plastic water pipe flows back to the water-heated blanket unit and is heated again. This cycle is repeated to continuously heat the blanket. Heat is continuously conducted in a closed-loop system. The blanket itself does not contain any electric heating elements, which allows for water and electricity separation during the heating process, resulting in high safety. Existing water-heated blanket units typically include a casing, a heating water tank, and a water pump. The presence of the heating water tank leads to the following problems: (1) More water pipes are needed to connect the various components, resulting in more connection interfaces, higher material costs, and a greater probability of leakage; (2) The assembly of the pipes and components is more complex, leading to longer assembly times and higher requirements.

[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0004] The existing technology of water-heated blankets typically features a separate design for the main unit, heating water tank, and water pump, requiring more water pipes to connect the various components. This results in more connection interfaces, higher material costs, and a greater risk of leakage. Furthermore, the assembly of the pipes and components is more complex, leading to longer assembly times and higher requirements. The technical solution adopted by this utility model to solve these problems is: a water pump specifically designed for water-heated blanket main units. The water pump includes: a pump casing, a rotor assembly, and a heating element. The pump casing has a heating chamber and an inlet communicating with the heating chamber. The heating element is connected to the pump casing to heat the water in the heating chamber. The pump casing also has a working chamber communicating with the heating chamber and an outlet communicating with the working chamber. The rotor assembly is connected to the working chamber and has an impeller for pumping the hot water from the heating chamber through the working chamber and out through the outlet. The pump casing also has a coil winding for driving the rotor assembly to rotate.

[0005] As described above, a water pump specifically designed for a water-heated blanket main unit includes a pump casing comprising: a lower housing and a water impeller cover, the water impeller cover being sealed and connected to the lower housing, the working chamber being disposed at the connection between the lower housing and the water impeller cover, the heating chamber being disposed on the water impeller cover, the water impeller cover having a connecting hole for communicating with the working chamber and the heating chamber, the water inlet being disposed on the water impeller cover, and the water outlet being disposed on the lower housing and / or the water impeller cover.

[0006] As described above, a water pump specifically designed for a water-heated blanket main unit has an opening on the water leaf cover that communicates with the heating chamber, and the heating element is flat and sealed to the opening.

[0007] As described above, a water pump specifically designed for a water-heated blanket main unit includes a rotor assembly comprising a ceramic shaft, a permanent magnet, and two bushings. The two bushings are respectively fitted onto both ends of the ceramic shaft, and the permanent magnet and impeller are connected to the ceramic shaft.

[0008] As described above, a water pump specifically designed for a water-heated blanket main unit has a first positioning groove on the water blade cover for positioning one end of the ceramic shaft, and a second positioning groove on the lower housing for positioning the other end of the ceramic shaft.

[0009] As described above, a water pump specifically designed for a water-heated blanket main unit has a clearance housing on its lower housing for avoiding a permanent magnet. The clearance housing is cylindrical, and its inner cavity communicates with the working cavity. The coil winding is located outside the clearance housing, so that the permanent magnet is located inside the coil winding.

[0010] As described above, a water pump specifically designed for a water-heated blanket main unit has a detection port on the water leaf cover that communicates with the heating chamber, and a temperature sensor for detecting the temperature of the water in the heating chamber is installed inside the detection port.

[0011] The beneficial effects of this utility model are: 1. This utility model discloses a water pump specifically designed for a water-heated blanket main unit. By setting a heating chamber and a working chamber connected to the heating chamber on the pump casing, the coil winding drives the rotor assembly and impeller to rotate, thereby pumping hot water in the heating chamber through the working chamber and out of the outlet. Cold water can be continuously replenished into the heating chamber through the inlet, realizing both water heating and water transportation. This overcomes the problems of existing water-heated blanket main units, which require a dedicated heating water tank and corresponding water circuits to connect various components, resulting in higher leakage risk and higher material and assembly costs. When used in a water-heated blanket main unit, it has the advantages of simple structure, reduced cost, and simplified assembly. Attached Figure Description
