The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Fig. 1 is a schematic view of an overall structure of a fixed-point high-precision temperature measuring device in an embodiment of the present invention, fig. 2 is a schematic view of an internal structure of the fixed-point high-precision temperature measuring device in the embodiment of the present invention, and fig. 3 is a schematic view of a partially enlarged structure of a sensing portion in the embodiment of the present invention. It should be noted that, for clarity and illustration, only the outline structure of the sensing portion is shown in fig. 1 and fig. 2, and the specific structure of the sensing portion is not shown, and the structure of the sensing portion is understood with reference to fig. 3.

Specifically, the embodiment of the invention provides a fixed-point high-precision temperature measuring device which comprises an operating handle 1, a main body part 2 and an induction part 3; the operating handle 1 is used for operating the bending action of the sensing part 3, the main body part 2 is used for processing data and displaying the data, and the sensing part 3 is used for adjusting the bending direction and the bending degree according to the requirements of a user, so that the temperature measuring device can accurately contact the heating plate under remote control.

Specifically, referring to fig. 3 of the drawings, the sensing part 3 includes a main spring 101, a temperature measuring device 33 and a twisting device 103, wherein the temperature measuring device 33 is disposed at the end of the main spring 101; each of said twisting means comprises at least three controllable coils 103, said twisting means being arranged on at least two turns of said body spring 101. Specifically, in a default state of the main body spring 101, a little gap is formed between two adjacent turns of coils for movement; the controllable coils 103 on two adjacent twisting devices can generate interaction force under control, so that the coils where the two twisting devices are located can move relatively (due to the limitation of the springs, the relative movement is generally relative twisting), and the main body spring 101 can be bent to change the position of the temperature measuring device 33, so that the temperature measuring device 33 can well contact with a measured object according to the actual environment, and the purpose of accurately measuring the temperature of the measured object is achieved.

According to the principle of spatial motion, in order to ensure that the acting force generated between the two sets of temperature measuring devices 33 can maximize the freedom of motion between the two sets of temperature measuring devices, each set of temperature measuring device 33 at least needs three sets of three controllable coils which are not arranged on the same straight line, and the controllable coils are arranged on the main body spring 101, so that the three sets of controllable coils can be ensured to be not arranged on the same straight line.

Furthermore, in order to facilitate adjustment, the controllable coil in each twisting device is uniformly arranged on the corresponding one-turn spring, so that the effective movement position of the coil on which the twisting device is arranged can be adjusted.

Further, since the interaction force generated between the controllable coils of the twisting device is limited, generally, the modulus of the spring is generally small, and in order to maintain the structure of the sensing part, the sensing part optionally further comprises a soft holding rod 102; the soft holding rod 102 is disposed inside the main body spring 101. The advantage of keeping the soft rod 102 is that the strength of the deformation ability of the main spring 101 can be not considered during processing, the material with smaller modulus can be processed more easily during processing, the structure of the sensing part 3 is kept mainly depending on the completion of keeping the soft rod 102, the soft rod 102 is kept to have certain bending ability, and the strength of the bending ability can be well controlled through the component change of the material, compared with the main spring 101, the manufacturing difficulty is greatly reduced, and the complexity of the processing procedure is facilitated to be simplified.

Furthermore, the controllable coil 103 and the temperature measuring device 33 need to be electrically connected with the central control module to transmit signals, so that the main body spring can be formed by winding a hollow pipe, and the pipe can realize the function of the main body spring; further, a connecting wire 104 is arranged inside the pipe, and the temperature measuring device 33 and the controllable coil 103 are electrically connected to the central control module based on the connecting wire 104.

Specifically, the main body part 2 includes a protective shell 23, a digital display module 21, a switch button 22, a mode button 24 and a central control module, the digital display module 21, the switch button 22, the mode button 24 and the central control module are disposed on the protective shell 23, and in addition, the main body part 2 should further include a power supply module 212 for supplying power.

Specifically, the digital display module 21 is composed of a data conversion module installed in the protective shell 23, an a/D conversion module, and a liquid crystal display screen installed on the front panel surface of the protective shell 23.

Specifically, the operating handle includes a grip 400 and a direction control button 401, and the direction control button 401 is disposed on the grip.

Specifically, the starting end of the main spring 101 and one end of the handle 400 are connected to the protective case 23.

Fig. 4 is a schematic diagram showing a circuit connection structure of the fixed-point high-precision temperature measuring device according to the embodiment of the invention. Specifically, the temperature measuring device 33, the controllable coil 103, the direction control button, the switch button, the mode button, and the digital display module are electrically connected to the central control module, and additionally, the power supply module is responsible for supplying power to each electric component.

Specifically, when the fixed-point high-precision temperature measuring device provided by the embodiment of the invention is used, the operation principle is as follows: the switch button is used for controlling the device to be started and closed, specifically, the control mode of controlling the device by the switch button can be that the switch button is used for controlling the power supply condition of the power supply module to other components (namely the switch button is connected between the power supply module and each component and is used for controlling the power supply of each component), or the switch button is used for sending a corresponding instruction to the central control module and triggering the central control module to be started, and the control can be implemented according to the actual condition in specific implementation; after the device is started, the central control module drives the digital display module to display the current setting conditions of the equipment, such as the current mode of the equipment, the unit of temperature display and the like, and the specific setting conditions can be adjusted by using a mode button; the direction control button is used for sending a corresponding trigger command to the central control module according to the trigger condition of the user; specifically, for convenience of use, the direction control button is generally an eight-direction or four-direction dial, and according to the operation condition of a user, the trigger signals of the dial are different, and the trigger signals which can be received by the central control module are also different; through the comparison relationship between the preset dial signal and the triggering condition of the controllable coils, the central control module controls the electrifying condition (current magnitude and/or current direction) of each controllable coil, so that corresponding interaction force is generated among different controllable coils, a main body spring is controlled to generate specific deformation, the appearance structure of the induction part can adapt to the field environment, and an obstacle is bypassed to a certain extent, so that the temperature measuring device can be in direct contact with a measured object.

Specifically, the control of the controllable coil by the central control module can be performed in the following manner: each controllable coil is provided with two power supply ends, each power supply end is connected with two electrodes of the power supply module through two electronic switches, the electronic switches are controlled through the central control module, the electrode access direction of the controllable coil can be controlled, and therefore the magnetic field generation direction of the controllable coil is controlled.

In particular, with regard to the regulation of the current, a digital potentiometer may be connected in the line.

Specifically, as the temperature measuring device is positioned at the tail end of the main body spring, in order to prevent the temperature measuring device from being damaged by collision during movement, a silica gel sleeve for protection is sleeved at the position of the temperature measuring device; specifically, the thickness of the silica gel sleeve is thin, so that the temperature measurement result is not influenced.

Optionally, the handle is made of an insulating material, and the insulating material can ensure the use safety of a user.

Further, for the central control module, the direction of the power control of the controllable coil is relatively corresponding to the direction control button, and the operation of the direction control button by the user is also corresponding to the visible twisting direction of the main body spring, in order to ensure the consistency of the three, the relative positions of the starting ends of the handle and the main body spring are kept fixed, and the handle and the main body spring can be kept connected and fixed inside the main body part 2 based on the connecting piece; accordingly, the main body portion 2 (including the protective case) can be rotated in the axial direction of the start ends of the handle and the main body spring. Through the setting direction, the actual operation direction of a user, the visual bending direction of the main body spring required by the user and the bending direction of the main body spring controlled by the central control module after receiving an instruction triggered by the direction control button are kept consistent, so that disorder of the directions is avoided; in addition, the relatively rotatable design of the main body part 2 can facilitate the user to conveniently operate and observe data according to different holding modes, and the use convenience is improved.
