Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of liquid heating equipment, and particularly relates to a device for heating liquid by PTC ceramic heating rod. BACKGROUND

[0002] The PTC thermistor is a typical temperature-sensitive semiconductor resistor, and its resistance value increases step by step with the increase of temperature when the temperature exceeds a certain value. The PTC heating refers to the technology of heating by using the PTC heating body. The working voltage is 12V, the PTC heating body is composed of a PTC ceramic heating element and an aluminum pipe, has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant-temperature and power-saving electric heater. The outstanding feature is safety performance, and the surface of the electric heater will not be red as the electric heating tube type heater, so that the safety hazards such as scalding and fire are avoided. The PTC heating body is composed of a galvanized outer pressing plate, a stainless steel corrugated spring sheet, a galvanized inner pressing plate, a single-layer aluminum heat dissipation piece, a PTC heating sheet, a double-layer aluminum heat dissipation piece, a nickel-plated copper electrode terminal and a pps high-temperature plastic electrode sheath. The working principle is that the U-shaped corrugated heat dissipation sheet is adopted to improve the heat dissipation rate, and the advantages of glue and mechanical type are combined, so that the heat conduction and heat dissipation performance are excellent, the efficiency is high, and the safety is reliable.

[0003] In the field of liquid heating, the traditional heating method has many disadvantages. The traditional hot bath heating liquid method will cause obvious temperature loss after the liquid passes through the instrument, which leads to extremely low heating efficiency and is difficult to meet the demand for rapid and stable temperature rise of the liquid in actual application.

[0004] The traditional heating tube heating liquid method usually adopts a spiral electric heating wire placed in a metal pipe and filled with MgO powder to form an electric heating tube as an electric heating element. This electric heating tube has serious safety hazards when working, and the working voltage is often 220V. Once an electric shock accident occurs, it may cause electric shock injury to the operator. In the case of no water or poor heat dissipation, the surface temperature of the electric heating tube will rise sharply and even become red, which can easily cause scalding and increase the risk of fire.

[0005] With the increasing requirements of safety and efficiency of liquid heating in various industries, such as precise heating of liquid for treatment or experiment in the medical industry, control of reaction temperature of specific liquid in the chemical industry, etc., a new liquid heating device is urgently needed to overcome the defects of the traditional heating method. Under this background, the device for heating liquid by PTC ceramic heating rod is born, which is committed to solving the problems in the prior art and providing a safer and more efficient solution for liquid heating. CONTENT OF THE UTILITY MODEL

[0006] Therefore, the PTC ceramic heating rod liquid heating device provided by the utility model can realize efficient liquid heating under the premise of ensuring safety, and can effectively solve the safety problems of traditional 220V heating tube liquid heating, and can ensure that the heating efficiency meets the actual application requirements, avoid temperature loss and low efficiency of the traditional hot bath heating mode, accurately and stably heat the liquid, meet the strict requirements of the medical and chemical industries on liquid heating, and provide a reliable and practical liquid heating solution for the related field.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a kind of PTC ceramic heating rod liquid heating device, comprising: PTC ceramic heating pipe, for heating liquid;

[0008] Temperature sensor is arranged near PTC ceramic heating pipe, for detecting the temperature of heating space and transmitting signal;

[0009] Liquid-electric separation platform, PTC ceramic heating pipe and temperature sensor pass through the liquid-electric separation platform, and sealing gasket is arranged between it and relevant components;

[0010] Bottom cover is located at the bottom of device and is sealingly connected with the bottom of liquid-electric separation platform;

[0013] Heating pipe lock nut is used to lock and fix PTC ceramic heating pipe and temperature sensor on liquid-electric separation platform;

[0014] Upper sealing gasket of separation platform is arranged on the upper portion of liquid-electric separation platform to realize sealing;

[0015] Heating pipe circuit conversion connector is connected with PTC ceramic heating pipe circuit to realize circuit conversion or connect external power supply, so that the device operates under 12V working voltage, when liquid enters heating space and contacts PTC ceramic heating pipe to make circuit conductive, temperature sensor can transmit detected temperature signal to micro processing chip on main circuit board, micro processing chip instructs PTC ceramic heating pipe to work according to signal, so that the temperature in heating space is kept between 43±0.5℃.

[0016] Further, the liquid-electric separation table is made of insulating and corrosion-resistant material, the internal channel size of which is matched with the PTC ceramic heating pipe and temperature sensor, so as to ensure close installation and effective liquid-electric separation.

[0017] Further, the heating pipe insulating gasket is made of high-temperature-resistant and good insulating material, so as to ensure good insulating effect during device operation and prevent circuit short circuit.

[0018] Further, the lower sealing gasket and the upper sealing gasket of the separation table are both made of elastic sealing material, which can effectively fill the gap when being pressed, so as to prevent leakage of the liquid medicine and entry of external liquid or impurities into the device.

[0019] Further, the heating pipe lock nut has good fastening performance and corrosion resistance, so as to ensure stable position of the PTC ceramic heating pipe and temperature sensor during device use, and prevent loosening or displacement.

[0020] The above technical scheme has at least the following beneficial effects:

[0021] 1. The working voltage is set to 12V, which greatly reduces the risk of electric leakage compared with the traditional 220V heating pipe, and fundamentally reduces the possibility of electric shock injury to the operator due to electric leakage. At the same time, the PTC ceramic heating rod will not produce the surface "red" phenomenon like the electric heating tube type heater in any application, effectively avoiding the occurrence of scalding accidents, providing a safe and reliable operating environment for the user. Whether it is in the medical industry for fine heating treatment of liquid medicine, or in the field of chemical liquid heating application, the personal safety of the operator can be ensured.

[0022] 2. Through the cooperative work of the temperature sensor and the micro-processing chip on the main circuit board, the temperature of the liquid medicine in the heating space can be accurately monitored and controlled. The temperature of the liquid medicine is always kept stable at 43±0.5℃. This high-precision temperature control capability is crucial for some temperature-sensitive liquid medicine processing. In the medical field, for example, the heating infusion of some specific medicines, precise temperature control can ensure the activity and efficacy of the medicine are not affected; in chemical experiments, it can also ensure that the chemical reaction proceeds stably under the predetermined temperature condition, improving the accuracy and reliability of the experimental results.

[0023] 3. Using PTC ceramic heating tubes as the heating element offers advantages such as low thermal resistance and high heat exchange efficiency. Compared to traditional hot bath heating methods, this significantly improves heating efficiency and reduces heating time. This not only increases production efficiency but also rapidly meets the needs of scenarios requiring quick heating of pharmaceutical solutions, such as emergency medical treatment. Furthermore, it reduces energy consumption, aligning with the development concept of energy conservation and environmental protection, thereby lowering production costs and improving economic benefits for enterprises.

[0024] 4. The design of the liquid-electric separation platform and the coordination of various sealing gaskets and lock nuts ensure the sealing and stability of the device. The liquid-electric separation platform effectively avoids short circuits caused by liquid contact with the circuit, ensuring the safe operation of the device; the sealing gaskets on the lower and upper parts of the separation platform prevent leakage of the liquid and the entry of external impurities, maintaining the cleanliness and stability of the internal environment of the device; the lock nuts on the heating tubes ensure the secure installation of the PTC ceramic heating tubes and temperature sensors, reducing the risk of failure due to loose components, extending the service life of the device, and reducing equipment maintenance costs.

[0035] A heating tube lock nut (7) is used to lock and fix the PTC ceramic heating tube (1) and the temperature sensor (2) on the liquid-electric separation table (3);

[0036] An upper separation table sealing gasket (8) is arranged on the upper part of the liquid-electric separation table (3) to achieve sealing;

[0037] A heating tube circuit conversion connector (9) is connected to the circuit of the PTC ceramic heating tube (1) to realize circuit conversion or connect an external power supply, so that the device operates under a working voltage of 12V. When the liquid medicine enters the heating space and contacts the PTC ceramic heating tube (1), the circuit is turned on, and the temperature sensor (2) can transmit the detected temperature signal to the micro-processing chip on the main circuit board. The micro-processing chip instructs the PTC ceramic heating tube (1) to work according to the signal, so that the temperature in the heating space is maintained at 43±0.5℃.

[0038] Further, the liquid-electric separation table (3) is made of an insulating and corrosion-resistant material, and the size of the internal passage is matched with the PTC ceramic heating tube (1) and the temperature sensor (2), so as to ensure tight installation and effective liquid-electric separation.

[0039] Further, the heating tube insulation gasket (5) is made of a material with good high-temperature resistance and insulation performance, which can ensure good insulation effect during the operation of the device and prevent circuit short circuit.

[0040] Further, the lower separation pad gasket (6) and the upper separation pad gasket (8) are both made of elastic sealing material, which can effectively fill the gap when being pressed, preventing the leakage of the liquid medicine and the entry of external liquid or impurities into the device.

[0041] Further, the heating tube lock nut (7) has good fastening performance and corrosion resistance, ensuring the stability of the positions of the PTC ceramic heating tube (1) and the temperature sensor (2) during the use of the device, and preventing loosening or displacement.

[0042] The liquid medicine enters the heating space, thereby making the circuit conductive, so that the PTC ceramic heating tube 1 can work normally. When the medicine enters the heating space and contacts the PTC ceramic heating tube 1, the medicine is heated. The temperature sensor 2 detects the temperature of the heating space and transmits a signal to the micro-processing chip on the main circuit board, and the micro-processing chip transmits an instruction to the PTC ceramic heating tube 1, so that the temperature in the heating space is always maintained at 43±0.5℃.

[0043] The PTC ceramic heating tube 1 and the temperature sensor 2 are assembled with a heating tube insulating gasket 5, and then locked by a heating tube lock nut 7 after passing through the liquid-electric separation platform 3. The liquid-electric separation platform 3 and the bottom cover 4 are provided with a separation platform lower sealing gasket 6, and the upper part of the liquid-electric separation platform 3 is provided with a separation platform upper sealing gasket 8.

[0044] In this embodiment, the liquid medicine heating operation is as follows:

[0045] When the liquid medicine enters the heating space, the liquid medicine contacts the PTC ceramic heating tube (1), at which time the circuit is conductive and the device starts to work. The temperature sensor (2) detects the temperature of the liquid medicine in the heating space in real time and transmits a temperature signal to the micro-processing chip on the main circuit board. The micro-processing chip judges according to the received temperature signal, and if the temperature is lower than the set 43℃-0.5℃, an instruction is sent to the PTC ceramic heating tube (1) to increase the heating power; if the temperature is higher than the set 43℃+0.5℃, the heating power is reduced, so that the temperature of the liquid medicine in the heating space is always maintained at 43±0.5℃.

[0046] The device for heating liquid medicine by the PTC ceramic heating rod provided in this embodiment realizes the liquid medicine heating function based on the characteristics of the PTC ceramic heating rod and the circuit control principle. Under the working voltage of 12V, the PTC ceramic heating tube (1) utilizes its own PTC effect to heat the liquid medicine when the temperature is low, the resistance is small, and the current is large. As the temperature rises, the resistance gradually increases, the current decreases, and the heating power automatically decreases, achieving a certain degree of automatic constant temperature control.

[0047] The temperature sensor (2) continuously monitors the temperature of the liquid medicine in the heating space as a feedback element, and converts the temperature data into an electrical signal and transmits it to the micro-processing chip on the main circuit board. The micro-processing chip accurately regulates the working state of the PTC ceramic heating tube (1) according to the preset temperature range (43±0.5℃). When the temperature deviates from the set range, the micro-processing chip changes the heating power by adjusting the voltage or current of the heating tube, so that the temperature of the liquid medicine quickly returns to the set range, ensuring that the liquid medicine is always in a stable heating state, meeting the requirements of various application scenarios for the heating precision of the liquid medicine.

[0048] Although the embodiments of the utility model have been shown and described above, it can be understood that the above-mentioned embodiments are exemplary and cannot be understood as limiting the utility model, and those skilled in the art can change, modify, replace and modify the above-mentioned embodiments within the scope of the utility model.
