Description

Technical Field

[0001] This utility model relates to the field of heating device technology, specifically to an organic silicone thermally conductive paint electric heating tube with automatic temperature sensing and water shortage protection functions. Background Technology

[0002] Electric heating elements are a common heating device widely used in industrial heating and household appliances. Currently available electric heating elements consist of a heating wire, insulating magnesium oxide, lead-out rods, and a metal tube.

[0003] However, during continuous operation, these heating elements, lacking protection for the heating surface, are prone to accelerated aging and decreased thermal efficiency. The absence of an automatic temperature regulation mechanism means they cannot automatically sense the actual temperature of the liquid being heated, easily causing the surface temperature to exceed the safety threshold. This leads to a short lifespan for the heating element and easy carbonization of the insulating magnesium oxide, resulting in leakage or burnout. Furthermore, existing heating element products lack an effective water shortage detection structure, posing a risk of dry burning in liquid heating applications, causing the heating wire to melt and the element itself to be damaged. Therefore, the shortcomings of existing heating elements—lack of protective materials for the heating surface, inaccurate temperature control, and lack of water shortage protection—urgently need to be addressed. Summary of the Invention

[0004] In view of this, the present invention provides an organic silicone thermally conductive paint electric heating tube with automatic temperature sensing and water shortage protection functions to solve the defects of electric heating tubes, such as short service life, inaccurate temperature control and lack of water shortage protection.

[0005] To solve the above-mentioned technical problems, the present invention provides an organic silicone thermally conductive paint heating element with automatic temperature sensing and water shortage protection functions, which adopts the following technical solution: An organic silicone thermally conductive paint heating element with automatic temperature sensing and water shortage protection functions includes an insulating plastic component. One end of the insulating plastic component is provided with a heating element for heating the liquid. Corresponding sides of the insulating plastic component are respectively provided with water shortage power-off protection probes for detecting whether the heating element is in normal contact with the liquid. When the water shortage power-off protection probes do not contact the liquid, the heating element automatically disconnects the power supply and stops working. A temperature sensing probe is provided on the insulating plastic component between the water shortage power-off protection probes to monitor the liquid temperature at all times. One end of the insulating plastic component is connected to a plug for supplying power to and controlling the organic silicone thermally conductive paint heating element via a power cord.

[0006] The heating assembly includes a heating tube mounted on an insulating plastic part, and a stainless steel cylinder is fitted around the heating tube. One end of the stainless steel cylinder is provided with a bottom splash-proof plastic part, which is a semi-circular sleeve.

[0007] An organosilicon thermally conductive layer is coated on the surface of the heating element.

[0008] The outer circumferential surface of the stainless steel cylinder is provided with evenly spaced circular holes in a ring, centered on the center of the stainless steel cylinder.

[0009] The plug includes an upper shell and a lower shell that snaps into the upper shell. An electronic display screen is provided on the surface of the upper shell, and a push-button switch is provided on the surface of the upper shell below the electronic display screen. The lower shell has pins for inserting the plug into a socket.

[0010] The lower shell contains a circuit board, which includes an adjustable automatic temperature sensing module, a control assembly circuit switch module, a water shortage power failure protection control module, and an alarm buzzer. When the upper shell is fastened onto the lower shell, the push-button switch and the control assembly circuit switch module are aligned vertically to facilitate operation of the control assembly circuit switch module by the push-button switch.

[0011] The temperature sensing probe, the water shortage power failure protection probe, and the insulating plastic parts are integrally molded.

[0012] The above-mentioned technical solution of this utility model has at least the following beneficial effects: 1. By setting up an insulating plastic part, two water shortage power failure protection probes set on the insulating plastic part, a water shortage power failure protection control module, and a control assembly circuit switch module, the water level of the liquid can be monitored when the heating tube heats the liquid. If the liquid decreases too much, the water shortage power failure protection probe will not contact the liquid, and the heating tube will stop working to avoid dry burning, which could cause the heating wire to melt and the tube body to be damaged.

[0013] 2. By setting a temperature sensing probe and an adjustable automatic temperature sensing module, the liquid temperature can be monitored in real time and displayed on an electronic display screen. Once the liquid temperature reaches the set temperature, heating stops, thus achieving automatic temperature regulation and enabling the heating element to precisely control the liquid temperature.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0018] Example 1 of the silicone thermally conductive paint heating element with automatic temperature sensing and water shortage protection provided by this utility model: like Figure 1-6 As shown: An organic silicone thermally conductive paint heating tube with automatic temperature sensing and water shortage protection functions includes an insulating plastic part. One end of the insulating plastic part is provided with a heating component for heating liquid. To achieve the heating of liquid, the heating component includes a heating tube 12 disposed on the insulating plastic part. A stainless steel cylinder 1 is sleeved on the outside of the heating tube 12. By setting the stainless steel cylinder 1, the heating tube 12 can be prevented from directly contacting the container containing liquid. Circular holes 10 are evenly distributed in a ring around the center of the stainless steel cylinder 1 on the outer circumference of the stainless steel cylinder 1. The circular holes 10 allow water to flow normally between the inside and outside of the stainless steel cylinder 1, which facilitates the heating tube 12 to heat it.

[0019] After the silicone thermal conductive paint heating element has finished heating the liquid, it is necessary to remove the silicone thermal conductive paint heating element from the liquid. In order to avoid large water splashes when removing it due to the high temperature of the heating element 12, a bottom anti-splash plastic part 11 is provided at one end of the stainless steel cylinder 1. The bottom anti-splash plastic part 11 is a semi-circular sleeve.

[0020] Furthermore, an organosilicon thermal conductive layer 13 is coated on the surface of the heating tube 12. The organosilicon thermal conductive layer 13 is an organosilicon thermal conductive paint, which is uniformly sprayed onto the outer surface of the heating tube 12 by coating. The organosilicon thermal conductive paint has excellent thermal conductivity, insulation and environmental stability. The heating tube 12 coated with organosilicon thermal conductive paint can efficiently conduct heat to heat the liquid.

[0021] To avoid the risk of dry burning during liquid heating, the corresponding sides of the insulating plastic parts are equipped with two water shortage power-off protection probes 33 for detecting whether the heating element is in normal contact with the liquid. When the water shortage power-off protection probe 3 is not in contact with the liquid, the heating tube 12 automatically disconnects the power and stops working.

[0022] Meanwhile, in order to enable the silicone thermally conductive paint heating element to automatically sense the actual temperature of the liquid to be heated in real time, a temperature sensing probe 4 is provided on the insulating plastic part between the water shortage power failure protection probe 3 to monitor the liquid temperature at all times. By setting the temperature sensing probe 4 and the adjustable automatic temperature sensing module 14, the silicone thermally conductive paint heating element can automatically adjust the water temperature. One end of the insulating plastic part is connected to a plug for powering and controlling the silicone thermally conductive paint heating element through a power cord 5.

[0023] Specifically, the plug includes an upper shell 6 and a lower shell 7 that snaps into the upper shell 6. An electronic display screen 8 is provided on the surface of the upper shell 6, and a push-button switch 9 is provided on the surface of the upper shell 6 below the electronic display screen 8. The lower shell 7 is provided with pins 18 for inserting the plug into the socket.

[0024] More specifically, the lower shell 7 is equipped with a circuit board, which includes an adjustable automatic temperature sensing module 14, a control assembly circuit switch module 15, a water shortage power failure protection control module 16, and an alarm buzzer 17. When the upper shell 6 is fastened onto the lower shell 7, the push-button switch 9 corresponds vertically to the control assembly circuit switch module 15, so that the push-button switch 9 can operate the control assembly circuit switch module 15.

[0025] In this embodiment, the temperature sensing probe 4, the water shortage power failure protection probe 3, and the insulating plastic part are integrally formed.

[0026] When using the silicone thermally conductive paint heating element, first place one end of the heating element 12 into the liquid to be heated. Then, insert the plug 18 into the socket to power on the heating element. Press the button switch 9, and the heating element 12 will heat the liquid. The heating temperature will be displayed on the electronic display screen 8 in real time for the user to observe. During the heating process, the water shortage power-off protection probe 3 and the temperature sensing probe 4 are located in the liquid. Only then can the heating element heat normally. If the water shortage power-off protection probe 3 is not in contact with the liquid, the water shortage power-off protection control module 16 receives the signal and feeds it back to the control assembly circuit switch module 15. At this time, the control assembly circuit switch module 15 issues a command to cut off the power to the heating element, thereby preventing the heating element from burning dry and avoiding the risk of use.

[0027] During the heating process of the electric heating tube, under the action of the temperature sensing probe 4 and the adjustable automatic temperature sensing module 14, the electric heating tube can always monitor the temperature of the liquid in real time and display the monitored temperature on the electronic display screen 8.

[0028] Based on the above description in this specification, those skilled in the art will also understand that the following terms used, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," are terms indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0029] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
