Existing heating mechanisms mostly use metal titanium heating rods or stainless steel heating rod coatings as heating elements. Among them, metal titanium is widely used in the manufacture of heating rods due to its excellent corrosion resistance and high temperature performance, while stainless steel heating rods are selected for their good heat resistance and cost-effectiveness.

[0061] like Figure 1 As shown, this embodiment provides a liquid heating mechanism 1, including: an inner tank 10, an electric heating film 11 and an outer shell 12.

[0062] Among them, the inner pot 10 is arranged in the outer shell 12; the electric heating film 11 is coated on the inner wall of the inner pot 10; a gap is set between the outer shell 12 and the inner pot 10; the lower end of the outer shell 12 is provided with a water inlet 120, and the upper end is provided with a water outlet 121; and sealing components 13 are provided on the water inlet and the water outlet.

[0063] Specifically, in this embodiment, the inner liner 10 is set as a nano-quartz inner liner; the outer shell 12 is set as a nano-quartz outer shell; nano-quartz has the characteristics of fast heating, small thermal inertia, and can quickly reach the required temperature and good stability, which further avoids pollution to industrial pure water. In actual use, any material that can reduce pure water pollution and heat up quickly is suitable for the inner liner and outer shell of the utility model, and will not be described one by one here.

[0064] More specifically, in this embodiment, the electric heating film has a variety of superior characteristics compared to traditional electric heating elements. For example, with the same power and the same temperature rise, the electric heating film 11 saves about 30% energy compared to traditional electric heating elements. Moreover, the electric heating film is heated by radiating far-infrared waves, and its length is mainly concentrated between 5-13μm. It also does not contain heavy metal elements such as lead, mercury, cadmium, and hexavalent chromium, which is environmentally friendly and energy-saving. During operation, the electric heating film 11 has the advantages of no inductance, no electromagnetic waves, no light, stable performance, stable starting current, no impact on the circuit, voltage shock resistance, safety and reliability, etc. The applicable voltage range is: 6V-380V (AC / DC). Under reasonable temperature use, its service life is more than 10 times that of resistance wire. The electric heating film 11 used for water circulation can increase the pH value of water, increase the conductivity, and form ionized water, which cannot be achieved by other forms of heating elements. The thickness of the electric heating film 11 is set to 15nm to 50nm, such as 19nm, 25nm, 30nm, 40nm, and 45nm, so that the electric heating film 11 itself does not consume heat, has a small thermal inertia, and a fast thermal response speed (fast heating when powered on, and fast cooling when powered off). In actual use, the thickness of the electric heating film can be set arbitrarily according to needs, and will not be described in detail here. By setting the electric heating film 11 to fit tightly against the inner wall of the inner tank 10, that is, the electric heating film 11 is set to be annular and tightly attached to the annular inner wall of the inner tank 10 and sintered into one body, the electric heating film 11 and the inner tank 10 are very firm, and it is not easy to fall off when cut with tools such as knives, and it is not easy to oxidize, ensuring that there is no air gap between the electric heating film 11 and the inner tank 10, so that the liquid heating mechanism 1 has no convection loss during the heating process, can directly conduct heat, has a fast thermal response speed, high heating efficiency and uniform heating. It is also beneficial to realize the expansion of heat conduction area, greatly improve the heat transfer speed, and the electric heat conversion efficiency reaches more than 96%. In actual use, the electric heating film can be sintered into any shape as needed, which will not be described in detail here.

[0065] More specifically, in this embodiment, a water inlet 120 is provided at the lower end of the housing 12, and a water outlet 121 is provided at the upper end. As an example, the water outlet 121 is located on a surface away from the surface where the water inlet 120 is located; so that the liquid enters from the water inlet 120 at the lower end, is heated by the inner pot 10 heated by the electric heating film 11, and then flows out from the water outlet 121 at the upper end of the housing 12. In actual use, the relative positions of the water outlet and the water inlet of the liquid heating mechanism can be arbitrarily set as needed, and are not limited to this embodiment.

[0066] like Figure 2 and Figure 3 As shown, the utility model further provides a liquid heating system 2, which includes: M liquid heating mechanisms 1, and each liquid heating mechanism 1 is connected in series and / or in parallel through a connecting pipe 200, and M is a natural number greater than 1.

[0067] As an example, Figure 2 As shown, the number of liquid heating mechanisms 1 is set to three. In actual use, the number of liquid heating mechanisms can be arbitrarily set according to needs, and will not be described in detail here. The connecting pipe 200 is set to a Z-shaped connecting pipe, and the number of connecting pipes 200 is set to two. In actual use, the shape and number of connecting pipes can be arbitrarily set according to needs, and will not be described in detail here. The three liquid heating mechanisms 1 are connected in series through a Z-shaped connecting pipe. That is, the water outlet of the first liquid heating mechanism is connected to the water inlet of the second liquid heating mechanism through the first connecting pipe; the water outlet of the second liquid heating mechanism is connected to the water inlet of the third liquid heating mechanism through the second connecting pipe.

[0068] As example 2, Figure 3 As shown, the number of liquid heating mechanisms 1 is set to twelve, and each liquid heating mechanism 1 is connected in parallel. That is, the water inlet of each liquid heating mechanism 1 is connected to the water inlet confluence pipe, and the water outlet is connected to the water outlet confluence pipe; the water inlet and water outlet of each liquid heating mechanism 1 are not connected to each other. In actual use, the connection method between each liquid heating mechanism can be set arbitrarily according to needs, and will not be repeated here.

[0070] like Figure 4 As shown, the liquid heating device 3 further comprises a base plate 32. The water inlet mechanism 30, the water outlet mechanism 31 and the liquid heating system 2 are all fixed on the base plate 32 vertically.

[0071] Specifically, in this embodiment, each liquid heating mechanism 1 in the liquid heating system 2 is vertically arranged on the substrate 32, so that when the water inlet mechanism 30 provides liquid to the liquid heating system 2, the pressure range required to be provided is 0.5 to 5 pounds of force to make the liquid flow from bottom to top to the liquid heating system 2; for example, 0.8 pounds of force, 1.5 pounds of force, 3.5 pounds of force, 4.5 pounds of force. In actual use, any pressure value that can ensure that the liquid flows from bottom to top to each liquid heating mechanism is applicable to the utility model, and will not be described one by one here. At the same time, a leakage protection sensor 33 with strong anti-interference ability, high stability, high sensitivity and fast response speed is arranged on the edge of the substrate 32, so as to achieve the purpose of being able to quickly and accurately monitor liquid leakage, and provide important safety protection for the entire liquid heating device 3.

[0072] like Figure 4As shown, the water inlet mechanism 30 includes a water inlet confluence pipe 300, a water inlet pipeline 301, a filter 302, a voltage stabilizing component 303 and a flow sensor 304. The water inlet confluence pipe 300 is parallel to the substrate 32. The water inlet end of the water inlet confluence pipe 300 is connected to the water outlet of the water inlet pipeline 301, and the water outlet end is connected to the water inlet of the liquid heating system 2.

When each liquid heating mechanism 1 is connected in parallel, A first perforations are arranged on the side surface of the circumference of the water inlet confluence pipe 300 as water outlet ends, and A is a natural number greater than 1. Each first perforation is connected to the corresponding water inlet of each liquid heating mechanism 1, and the water inlet end is arranged at any one end of the two ends of the water inlet merging pipe 300 and connected to the water outlet of the water inlet pipe 301. In actual use, the position of the water outlet end of the water inlet merging pipe is determined based on the connection method between the liquid heating mechanisms, which will not be described one by one here.

[0073] Specifically, in the present embodiment, the filter 302, the voltage stabilizing component 303 and the flow sensor 304 are sequentially arranged on the water inlet pipe 301 from top to bottom. Among them, the filter 302 adopts a Y-type filter with simple structure, easy installation and high efficiency filtration, and the Y-type filter can evenly distribute the fluid, which helps to control the liquid flow rate and pressure well. In actual use, any device that can filter the liquid is applicable to the utility model, which will not be repeated here. The voltage stabilizing component 303 includes a pressure reducing valve 303a, a pressure gauge 303b, and a pressure switch 303c to ensure that the pressure during water inlet is sufficiently stable to ensure that the liquid heated by the liquid heating mechanism 1 flows out stably from bottom to top. In actual use, any voltage stabilizing component that can ensure that the liquid flows out stably from bottom to top is applicable to the utility model, which will not be repeated here. The flow sensor 304 is set as an ultrasonic flowmeter to achieve the purpose of non-contact measurement of liquid flow. In actual use, any flow sensor that can perform non-contact measurement of liquid flow is applicable to the utility model, which will not be repeated here. When the flow sensor 304 is provided, a liquid level meter (not shown in the figure) is also provided to prevent the liquid heating device 3 from being damaged due to the liquid level being too low during the heating process. The liquid level meter is provided as a capacitive liquid level meter or an ultrasonic liquid level meter to achieve non-contact measurement of the liquid level. In actual use, any liquid level meter that can perform non-contact measurement of the liquid level is applicable to the present utility model, and will not be described in detail here.

The water inlet end of the water outlet confluence pipe 310 is connected to the water outlet of the liquid heating system 2; the water outlet end of the water outlet confluence pipe 310 is connected to the water inlet of the water outlet pipeline 311. When each liquid heating mechanism 1 is connected in series, the water inlet end and the water outlet end of the water outlet confluence pipe 310 are respectively arranged at both ends of the water outlet confluence pipe 310. That is, the water inlet end of the water outlet confluence pipe 310 is connected to the water outlet of the last liquid heating mechanism 1 in the liquid heating system 2; the water outlet end is connected to the water inlet of the water outlet pipeline 311. When the liquid heating mechanisms 1 are connected in parallel, A second perforations are provided on the side of the circumference of the water outlet confluence pipe 310 as water inlet ends, and each second perforation is connected to the corresponding water outlet of each liquid heating mechanism 1, and the water outlet end is provided at any one end of the two ends of the water outlet confluence pipe 310 and connected to the water inlet of the water outlet pipe 311. In actual use, the position of the water inlet end of the water outlet confluence pipe is determined based on the connection method between the liquid heating mechanisms, which will not be described one by one here.

[0075] Specifically, in the present embodiment, the first temperature sensor 312 and the one-way valve 313 are sequentially arranged on the water outlet pipe 311 from bottom to top. The first temperature sensor 312 is arranged to monitor the temperature of the liquid on the water outlet pipe 311, thereby adjusting the working condition of the liquid heating mechanism 1, and realizing the control of heating or cooling the water, so as to make it approach the required temperature. The one-way valve 313 is arranged to prevent the liquid from flowing back on the water outlet pipe 311, ensuring that the liquid can only flow out from bottom to top, and is also used to maintain the positive pressure of the device, preventing the device from malfunctioning and being damaged due to negative pressure, thereby reducing costs. In actual use, the positions of the first temperature sensor and the one-way valve can be arbitrarily set as needed, and will not be described one by one here.

[0076] like Figure 4As shown, the liquid heating system 2 also includes N subunits 20, each subunit 20 is connected in parallel.

Wherein N=A. The liquid heating mechanism 1 is first connected in series through the connecting pipe 200 to form the subunit 20, and then the subunits 20 are connected in parallel to form the liquid heating system 2, which can flexibly change the connection relationship of the liquid heating mechanism to meet the production of a large amount of pure water required. In actual use, the connection method of the liquid heating structure in the subunit can be arbitrarily set according to needs, which will not be repeated here. The liquid heating device 3 also includes N second temperature sensors 34, each of which is arranged between the water outlet of each subunit 20 and the water inlet end of the water outlet confluence pipe 310; by setting a plurality of second temperature sensors 34, the outlet water temperature of each subunit 20 can be monitored in real time. Combined with the first temperature sensor 312, the heated liquid flowing out of the liquid heating device 3 can more accurately approach the required temperature without causing waste of liquid flowing out but the temperature not reaching the required temperature.
