The pressure differential electric heating core 2 is arranged inside or outside the heating medium 1, and can be installed on the left, right, vertically downward, or in other installation methods, and the pressure differential electric heating core 2 is connected to the heating medium 1;

[0043] This heater is an independent wet heating appliance with good comfort. Different from traditional water heating, it does not require bulky equipment such as wall-mounted boilers or air-energy heat source equipment. It does not require water distributors, multiple sets of valves, complex pipes, and professional construction and installation workers. It does not require the large infrastructure costs of centralized heating. There is no public heat loss, eliminating serious heat waste, no public operating costs, and no longer worries about pipe leaks or floor heating water seepage. It can achieve independent heating, room heating, and heating on demand without the need for water distributor room control. When heating, it can be used independently as a hot melt liquid pump heater, or it can be used in series with multiple terminals such as radiators. In other words, a liquid pump heater can be used as a heat source and pressure source to replace centralized heat sources such as wall-mounted boilers or air-energy, meeting the needs of distributed heating in households.

[0044] The hot melt liquid pump heating machine of the present application adopts a "one tube, multiple heads" structure, which reduces the number of molds and costs, and has high manufacturing efficiency; the whole machine is small in size, saving installation space, and at the same time, because the various pipe sections and the pipe sections and the branch pipes are formed by high-temperature hot melting, there are no welds inside the flow channel, which is not easy to accumulate scale, has high heat utilization efficiency, long service life, and is light in weight. It is an independently used water heating household appliance and engineering equipment. A liquid flow channel is formed between the upper multi-head pipe group 1-6, the branch pipe 1-2 and the lower multi-head pipe group 1-1. The liquid flow channel is used to carry a certain volume of liquid and dissipate the liquid heat energy through convection and conduction. Since the physical specific heat capacity of the liquid is large, the heat carrier also has a heat storage function, the heat medium temperature is stable, and the room temperature fluctuation is small, making the room comfortable and not dry.

[0045] As a preferred embodiment, the upper single multi-head pipe segment 1-5, the lower single multi-head pipe segment 1-4, the upper multi-head pipe segment 1-1-4, the lower multi-head pipe segment 1-1-1, the middle multi-head pipe segment 1-1-2, and the last multi-head pipe segment 1-1-3 are all one tube with N heads, where N is not less than 2; the center height between the upper and lower multi-head pipe groups is variable, and the number of heads of the multi-head pipe segment is also variable, which can be one tube with two heads, one tube with three heads, one tube with four heads, one tube with ten heads, etc. The upper and lower multi-head pipe groups can be composed of multi-head pipe segments with the same number of heads, or they can be composed of multi-head pipe segments with different numbers of heads. The number of columns of the branch pipes 1-2 varies with the total number of heads of the pipe segments of the multi-head pipe group. The number of heads of the upper and lower multi-head pipe groups and the number of columns of the branch pipes 1-2 can be arranged in one row, two rows, or multiple rows to form different appearances, thereby increasing the aesthetics and appearance diversity of the heater.

[0046] The upper manifold tube group 1-6, branch tubes 1-2, and lower manifold tube group 1-1 are all made of a thermally conductive material. The thermally conductive material can be a non-metallic material or a composite material, or a combination of multiple materials through injection molding, bonding, expansion sleeves, extrusion, or other methods. The thermally conductive material improves the thermal conductivity of the heat carrier 1. In this application, the heat carrier can be made into different colors through spraying, electrophoresis, or oxidation, or different pictures can be printed or pasted on it, and different pendants or decorative accessories can be configured to enhance the aesthetics of the cylindrical liquid pump heater.

[0047] As a preferred embodiment, the branch pipes 1-2 are provided with nested fins to increase the heat dissipation area; decorative caps can be added to the upper and lower manifold groups; the cross-section of the branch pipes 1-2 is elliptical, square, D-shaped or other special shapes, and the entire heat carrier can also be covered with different forms of outer shell shapes to form different appearances, increase aesthetics and shape diversity.

[0048] like Figure 7As shown, the pressure differential electric heating core 2 includes a pressure chamber static body component 2-1, a pressure chamber dynamic body component 2-2, a stator component 2-3, a rotor component 2-4, a differential pressure sleeve 2-5, a connecting frame 2-6, a heat converter 2-7, a sensor 2-8, a seal 2-9, a joint 2-10 and a pressure differential electric heating core terminal 2-11; the pressure differential electric heating core terminal 2-11 is connected to the system terminal of the control system 3; more specifically, the control system 3 is connected and installed at the end of the pressure differential electric heating core 2, or installed on the heat carrier 1, and the installation form can be horizontal, vertical wall-mounted or embedded, and a mobile structure can also be adopted to increase the appearance diversity of the columnar liquid pump heater;

[0049] The stator assembly 2-3 wraps the rotor assembly 2-4, and the rotor assembly 2-4 is connected to the pressure chamber dynamic body assembly 2-2 and drives the pressure chamber dynamic body assembly 2-2 to move. The stator assembly 2-3 and the rotor assembly 2-4 form a driving motor for driving the pressure chamber dynamic body assembly 2-2 to move at high speed; the pressure chamber static body assembly 2-1 is arranged outside the pressure chamber dynamic body assembly 2-2 and the rotor assembly 2-4, and the pressure chamber static body assembly 2-1 and the pressure chamber dynamic body assembly 2-2 adopt a blade type structural assembly to form a blade type liquid pump or adopt a volumetric structural assembly to form a volumetric liquid pump, that is, the pressure chamber dynamic body assembly 2-2 cooperates with the pressure chamber static body assembly 2-1 to form a liquid flow pressure difference; the differential pressure sleeve 2-5 is connected to the outside of the pressure chamber static body assembly 2-1, more specifically, the differential pressure sleeve adopts different materials and different forms of structures such as rubber rings, and is connected to the pressure chamber static body assembly and the heat carrier flow The heat converter 2-7 is connected to the pressure chamber static body assembly 2-1 or the stator assembly 2-3 through the connecting frame 2-6. The connecting frame 2-6 is a transition connection between the pressure chamber static body assembly 2-1 or the stator assembly 2-3 and the heat converter 2-7. The connecting frame 2-6 can adjust the axial distance between the pressure chamber static body assembly 2-1 or the stator assembly 2-3 and the heat converter 2-7; the sensor 2-8 is arranged on the heat converter 2-7, and the terminal of the heat converter 2-7, the sensor 2-8 and the power line of the stator assembly 2-3 are connected to the joint body 2-10 through the sealing member 2-9. More specifically, the heat converter, sensor, stator assembly wiring and joint body of the pressure differential electric heating core are sealed by a sealing ring, or a special-shaped silicone sleeve, or epoxy resin potting, or a single sealing method or a plurality of combined sealing methods in other sealing forms.

[0050] A liquid pump is formed between the static and dynamic components of the pressure chamber of the pressure differential electric heating core, which creates a pressure difference in the liquid flow inside the heater. This in turn causes the internal liquid flow to circulate actively, resulting in uniform liquid heating and consistent surface temperature. This reduces energy consumption, increases heat utilization efficiency, reduces scaling, and prolongs the lifespan. Furthermore, due to the low internal liquid pressure, there are no potential safety hazards such as pipe bursts and burns, greatly improving the safety of the heater.

[0051] Since the differential pressure sleeve adopts different materials and different forms of structures such as rubber rings, the differential pressure sleeve is connected between the static body component of the pressure chamber and the heat carrier flow channel, preventing the high-temperature liquid in the high-pressure area from directly flowing back to the low-pressure area, so that the internal liquid flow of the heater is actively circulated and the liquid inside the heater is evenly heated.

[0052] The pressure differential electric heating core terminal 2-11 includes a power connection terminal, a heat converter terminal, a stator assembly terminal and a sensor terminal; the sensor can collect parameters such as temperature and use them to control the start and stop and operating status of the equipment in real time.

[0053] The heat converter 2-7 is an electric heating monomer or assembly, and the heat converter is made of carbon fiber, rare earth thick film, graphene, ceramic, polymer composite material, nano coating or metal resistance wire, and the metal resistance wire includes stainless steel, nickel-chromium alloy, titanium alloy or tungsten-manganese alloy.

[0054] The structure of the connector 2-10 can be square or oval, and the connector can be connected to the heat conversion body by using threads, bolts, sleeves or other connection forms.

[0055] As a preferred embodiment, the sensors 2-8 in this application are single sensors or combined sensors, which collect parameters such as temperature, set programs, and control the start and stop and operating status of the pressure differential electric heating core in real time. If needed, the power of the pressure differential electric heating core and the speed of the liquid pump rotor can also be collected, and timed switching, intelligent control, and remote control can be performed. The vane-type liquid pump includes a centrifugal, mixed flow, or axial flow type, and the volumetric liquid pump includes a diaphragm, plunger, or screw type.

[0056] The control system 3 includes a controller 3-1 and a display 3-2. The controller 3-1 and display 3-2 can be integrated or split. Whether split or integrated, the controller 3-1 and display 3-2 can be in various shapes, such as circular, elongated, or other shapes. The installation method can be customized based on the overall structure of the device and user operation requirements.

[0057] The hot melt liquid pump heater of the present application may be vertical, horizontal or other structural forms; it may be fixed wall-mounted or embedded installation form, or it may be equipped with movable legs and adopt a mobile structure.
