Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent materials, in particular to a temperature-sensitive film coupled intelligent temperature regulating device and its feedback control method. BACKGROUND

[0002] In the field of intelligent materials, temperature-sensitive films, as a functional material that can adjust physical properties such as electrical conductivity and light transmittance with temperature changes, are widely used in electronic device temperature control, medical constant temperature devices, industrial sensing, etc. The performance of temperature-sensitive films highly depends on precise temperature control, which requires a dedicated regulating device to achieve dynamic stability of temperature. However, traditional temperature-sensitive film coupled temperature regulating devices have many technical shortcomings: poor connector connection stability, affected temperature control precision, and the connector and shell of traditional devices are usually fixed by bolts or simply plugged in. Although bolt fixation is firm, it requires the use of tools (such as screwdrivers) during assembly, which is tedious (5-10 minutes per assembly), and the bolts may rust after long-term use, making disassembly and maintenance difficult. Simple plugging method has no locking structure, and slight vibration (such as device movement, environmental resonance) during device operation can easily cause the connector to fall off, causing signal transmission interruption between the temperature-sensitive film and the device, and a sudden increase in temperature control error (deviation up to 1-2°C). In particular, in precise electronics, medical and other scenarios with high temperature precision requirements (such as temperature control precision of ±0.5°C), the traditional connection method is difficult to adapt. Therefore, we propose a temperature-sensitive film coupled intelligent temperature regulating device and its feedback control method. SUMMARY

[0003] The present application aims to provide a temperature-sensitive film coupled intelligent temperature regulating device and its feedback control method.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical solution: a temperature-sensitive film coupled intelligent temperature regulating device, comprising a shell, a connecting port is formed on the side of the shell, a connector is plugged into the inside of the connecting port, and an installation block is fixedly installed on the surface of the connector, a clamping groove is formed on the side of the installation block, a rectangular groove is formed on the left and right sides of the connecting port, and a fixed rod is fixedly installed in the inside of the rectangular groove, a clamping block is movably installed on the surface of the fixed rod, one end of the clamping block is clamped in the inside of the clamping groove, a spring is wound between the rectangular groove and the clamping block, and the spring surrounds the surface of the fixed rod.

[0005] As a further solution of the present application: a back-shaped groove is formed on the side of the shell, and a back-shaped block is fixedly installed on the side of the installation block.

[0006] As a further solution of the present application: a switch button and a temperature control knob are sequentially arranged on the side of the shell.

[0007] As a further scheme of the present application: the surface of the temperature control knob is provided with several anti-skid strips.

[0008] As a further scheme of the present application: one end of the clamping block is provided with a reverse rectangular design.

[0010] As a further scheme of the present application: a feedback control method applied to the intelligent temperature regulating device coupled with the temperature-sensitive film, comprising the following steps: S1, device preparation and inspection: confirm that the connector is inserted into the connection port of the shell, the reverse block on the side of the installation block is completely embedded into the reverse groove, and the clamping block is clamped into the clamping groove under the action of the spring; check that the switch button press rebound is normal, the temperature control knob rotation is not jammed, and the anti-skid strip is not worn; S2, device start: press the switch button to power the device and the coupled temperature-sensitive film, and the device enters standby state; S3, target temperature setting: rotate the temperature control knob, increase the hand friction force through the anti-skid strip, and accurately adjust to the preset target temperature; the temperature control knob corresponds to 1℃ of target temperature adjustment every 15° of rotation; after setting, the device records the target temperature parameter; S4, real-time temperature feedback: the temperature-sensitive film collects real-time temperature data, which is transmitted to the internal controller of the device through the connector; due to the clamping of the clamping block and the limiting of the reverse block, the connector has no deviation, the signal transmission has no interruption, and the feedback delay is less than or equal to 0.5s; S5, dynamic temperature regulation: the device controller compares the real-time temperature with the target temperature; if the real-time temperature is lower than the target temperature, the power of the heating element is automatically increased, and the power adjustment range matches the current gear of the temperature control knob (for example, the power is increased by 8% at a time when the knob is in the "middle gear"); if the real-time temperature is higher than the target temperature, the heating power is reduced or the refrigeration element is started until the deviation between them is less than or equal to 0.3℃, and the temperature of the temperature-sensitive film is maintained stable; S6, device shutdown: after completing the temperature control requirement, press the switch button to cut off the power supply, and when pulling out the connector, squeeze the clamping block to compress the spring, so that the clamping block is separated from the clamping groove, and the cooperation of the reverse block and the reverse groove is taken out at the same time.

[0011] As a further scheme of the present application: in step S4, the temperature collection frequency of the temperature-sensitive film is set to 2Hz, and the collection accuracy is ±0.1℃; when the real-time temperature data is transmitted through the connector, the clamping block only slides along the rectangular groove due to the limitation of the fixed rod, the spring is always in a tight state, the clamping gap between the clamping block and the clamping groove is less than or equal to 0.1mm, the signal transmission is avoided from fluctuating due to poor contact, and the temperature data error is less than or equal to 0.2℃.

[0012] As a further scheme of the present application: in step S5, the adjustment response time of the device controller is ≤0.3s; when the deviation between the real-time temperature and the target temperature exceeds 0.5℃, the current gear of the temperature control knob automatically triggers the "fast adjustment mode", for example, when the knob is in "high gear", the power adjustment range is increased to 10% / time, until the deviation is reduced to ≤0.3℃, and then the "stable adjustment mode" is switched back to maintain stable power output.

[0013] As a further scheme of the present application: between steps S4-S5, an abnormal feedback processing step is further included: if the device controller detects that the temperature signal interruption exceeds 1s, it is determined that the connector has a jamming abnormality, at this time, the fitting of the back-shaped block and the back-shaped groove limits the connector offset to ≤0.2mm, and the inverted rectangular structure of the clamping block prevents it from completely separating from the clamping groove; the device automatically reduces the heating / cooling element power to the minimum gear (power ≤10% of the rated value), while maintaining the on state of the switch button, and the staff checks the abnormality and re-fixes the connector by observing whether the back-shaped block is completely embedded in the back-shaped groove and whether the clamping block is clamped into the clamping groove, to restore the temperature feedback and adjustment functions.
