Description

Technical Field

[0001] This utility model relates to a dual-temperature-controlled water pump heating tube, belonging to the field of heater technology. Background Technology

[0002] Currently, in order to control the water temperature and perform self-protection during the heating process, a temperature controller and a fuse device or a one-time temperature controller are added to the circuit connecting the heating element and the power supply. The temperature controller is used to control the water temperature. When the water temperature reaches the set temperature, the temperature controller will automatically disconnect. If the temperature drops below the set temperature, the temperature controller will automatically reset. The fuse device or one-time temperature controller is used when there is no water in the cavity or shell of the heating element during use, and the heating element is in a dry-burning state. When the temperature reaches the melting temperature, the fuse device will disconnect, and the heating element cannot be repaired and can only be scrapped.

[0003] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a dual-temperature-controlled water pump heating tube, which would have greater industrial application value. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a dual-temperature-controlled water pump heating tube.

[0005] This utility model provides a dual-temperature-controlled water pump heating tube, including a flange, wherein multiple sealing teeth are evenly provided at the lower edge of the flange.

[0006] It also includes stainless steel heating elements;

[0007] The flange's upper outer edge is equipped with through holes and both an automatic reset thermostat and a manual reset thermostat. This effectively monitors the temperature of the working medium and the heating element. When the automatic reset thermostat detects the temperature of the working medium and the heating element, it cuts off power once the temperature reaches the controlled temperature. When the temperature drops to the automatic reset thermostat's reset temperature, the thermostat automatically resets, and the heating element resumes normal operation, repeating this cycle. If an abnormality occurs during heating, and the temperature rises sharply, exceeding the control temperature of the manual reset thermostat, the thermostat disconnects, and the heating element stops working. Pressing the manual reset thermostat's control button allows the heating element to continue operating, ensuring its continued operation, preventing it from becoming unusable, and improving its cyclical use. The flange's upper outer edge has two through holes through which the first and second cold ends of the stainless steel heating element pass. The first cold end is electrically connected to the automatic temperature control first terminal of the automatic reset thermostat via a first conductive wire; the second cold end is electrically connected to the manual temperature control first terminal of the manual reset thermostat via a second conductive wire.

[0008] Furthermore, the sealing teeth are rolled at the edges to secure them inwardly to the heater tank, thus improving the sealing performance.

[0009] Furthermore, the automatic reset thermostat and the manual reset thermostat are tightly fixed to the corresponding outer surface of the local brazing part of the heating tube by screws and nuts.

[0010] Furthermore, the stainless steel heating tube is arranged in a ring inside the flange, and the middle part of the stainless steel heating tube is fixedly attached to the lower surface of the flange by brazing.

[0011] Furthermore, the first conductive wire, the first cold end, and the automatic reset temperature controller are connected by spot welding.

[0012] Furthermore, the second conductive wire, the second cold end, and the manual reset temperature controller are connected by spot welding.

[0013] Furthermore, the automatic reset thermostat is also equipped with a second automatic temperature control connector for connecting an external power supply.

[0014] Furthermore, the manual reset thermostat is also equipped with a second manual temperature control connector for connecting an external power supply.

[0015] By means of the above-described solution, the present invention has at least the following advantages:

[0016] This invention connects the heating element to an external power supply and employs a dual-temperature controller design with both automatic and manual temperature control. When an abnormal environment occurs, if the manual temperature control is disconnected due to reasons other than the heating element itself, the temperature controller can be manually reset, ensuring that the heating element can continue to work, preventing it from becoming unusable, and improving the efficiency of its repeated use.

[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] See Figure 1 and Figure 2 The preferred embodiment of the present invention provides a dual-temperature-controlled water pump heating tube, including a flange 1. A plurality of sealing teeth 7 are evenly provided at the lower edge of the flange 1. The sealing teeth 7 are rolled on the edge to inwardly snap and fix them to the heater tank, thereby improving the snap-fit ​​sealing performance.

[0027] It also includes a stainless steel heating tube 2, a through hole and an automatic reset thermostat 3 and a manual reset thermostat 4 on the outer edge of the upper end face of the flange 1.

[0028] The automatic reset thermostat 3 and the manual reset thermostat 4 are tightly fixed to the corresponding outer surface of the local brazed part of the heating tube by screws 5 and nuts 6. They effectively monitor the temperature of the working medium and the heating tube. When the automatic reset thermostat 3 detects the temperature of the working medium and the heating tube, it cuts off the power after the temperature reaches the controlled temperature. When the temperature drops to the reset temperature of the automatic reset thermostat 3, it automatically resets and the heating tube resumes normal operation, thus completing the cycle. If an abnormality occurs during heating and the temperature rises sharply, exceeding the control temperature of the manual reset thermostat 4, the manual reset thermostat 4 disconnects, and the heating tube stops working. Pressing the control button of the manual reset thermostat 4 will allow the heating tube to work normally, ensuring continued operation, preventing the heating tube from being scrapped, and improving the efficiency of its cyclical use.

[0029] The flange 1 has two through holes on the outer edge of the upper end face, and the first cold end 21 and the second cold end 22 of the stainless steel heating tube 2 pass through the two through holes respectively.

[0030] The first cold end 21 is electrically connected to the first automatic temperature control terminal 31 of the automatic reset temperature controller 3 via the first conductive wire 23;

[0031] The second cold end 22 is electrically connected to the manual temperature control first terminal block 41 of the manual reset temperature controller 4 via the second conductive wire 24;

[0032] The stainless steel heating tube 2 is arranged in a ring inside the flange 1, and the middle part of the stainless steel heating tube 2 is fixedly attached to the lower surface of the flange 1 by brazing.

[0033] The first conductive wire 23, the first cold end 21, and the automatic reset temperature controller 3 are connected by spot welding.

[0034] The second conductive wire 24, the second cold end 22, and the manual reset temperature controller 4 are connected by spot welding.

[0035] The automatic reset temperature controller 3 is also provided with an automatic temperature control second terminal block 32 for connecting an external power supply line;

[0036] The manual reset temperature controller 4 is also provided with a manual temperature control second terminal block 42 for connecting an external power supply.

[0037] The working principle of this utility model is as follows:

[0038] In practical use, the dual-temperature-controlled water pump heating element of this invention first secures the sealing teeth 7 to the heater tank by rolling the edges, improving the sealing performance. Then, power is supplied to the entire device via the automatic temperature control second connector 32 and the manual temperature control second connector 42. When the automatic reset temperature controller 3 detects the temperature of the working medium and the heating element, it cuts off the power once the controlled temperature is reached. When the temperature drops to the reset temperature of the automatic reset temperature controller 3, it automatically resets, and the heating element resumes normal operation, thus completing the cycle. If an abnormality occurs during heating and the temperature rises sharply, exceeding the control temperature of the manual reset temperature controller 4, the manual reset temperature controller 4 disconnects, and the heating element stops working. Pressing the control button of the manual reset temperature controller 4 resumes normal operation of the heating element, ensuring continued operation, preventing the heating element from becoming unusable, and improving the efficiency of its cyclical use.
