In order to be able to detect the temperature of a food material or a food material processing medium (such as water) during cooking, the present application provides a temperature detection device. For convenience of use, the temperature detection device 1 may be of a hand-held type structure, as shown in fig. 1 and 2. Of course, in other embodiments, the temperature detecting device 1 may have a desktop structure or other structures.

Referring to fig. 1-4, in some embodiments, the temperature detection device 1 includes a detection assembly 100 and a device body 200.

The detection assembly 100 is movably connected to the device body 200, and a user can change the positions of the detection assembly 100 and the device body 200 to adapt to different application scenarios. For example, in the embodiment shown in fig. 1 and 2, the detection assembly 100 is rotatably connected to the device body 200, and the user can rotate the detection assembly 100 to change its position relative to the device body 200 to stop the detection assembly 100 at any angle within the range to facilitate different use requirements. Of course, in other embodiments, the detecting component 100 can be connected to the main body 200 in other movable manners, for example, the detecting component 100 can also be moved in a plane relative to the main body 200, and the moving path can be a straight line, a curved line, a broken line, or an irregular path. The plane can be a horizontal plane, a vertical plane, or other non-horizontal or vertical plane. In addition, the movement of the probe assembly 100 relative to the device body 200 may be other than rotational and translational movement.

The detecting assembly 100 has a temperature detecting unit 123 for detecting temperature, for example, the temperature detecting unit 123 may be but is not limited to a thermocouple, and the temperature detecting unit 123 may also adopt other devices that can be used for detecting temperature.

Referring to fig. 4, the main body 200 generally has a control unit 210, and the control unit 210 may be a circuit board having a control circuit, or may be other structures, circuits or a combination thereof capable of performing a control function. The temperature detection unit 123 is in signal connection with the control unit 210, the signal detected by the temperature detection unit 123 is transmitted to the control unit 210, and the control unit 210 processes the signal to obtain a temperature detection result, so that the temperature detection is realized.

For convenience of use, in some embodiments of the present application, the control unit 210 is triggered to be turned on or off by moving the detection assembly 100 while changing the position of the magnetic body. Referring to fig. 3-10, in some embodiments, the probe assembly 100 further includes a first magnetic body 110. The device main body 200 has a magnetic field signal detection unit 201, and the magnetic field signal detection unit 201 is in signal connection with a control unit 210. The magnetic field signal detection unit 201 is disposed at one side of the first magnetic body 110, and in the movement process of the first magnetic body 110, the magnetic field signal detection unit 201 is configured to detect a magnetic field signal of the first magnetic body 110, and the control unit 210 controls the temperature detection device 1 to be turned on or off based on a detection result of the magnetic field signal detection unit 201. The first magnetic body 110 may be a magnet or other structures capable of generating magnetism. In some embodiments, the first magnetic body 110 may be a permanent magnet (e.g., a permanent magnet), or the first magnetic body 110 may be an electromagnet (e.g., an electrified coil) or the like that can generate magnetism when being electrified or in other specific states.

The magnetic field signal detected by the magnetic field signal detecting unit 201 may be a magnetic field direction, a magnetic induction intensity, or other signals related to a magnetic field. In some embodiments, the magnetic field signal detection unit 201 may be a magnetic field direction detection unit 2011, and the magnetic field direction detection unit 2011 may be, but is not limited to, a magnetic tunnel sensor. The magnetic field signal detected by the magnetic field direction detection unit 2011 includes at least a magnetic field direction, and the magnetic field direction detection unit 2011 can also detect parameters related to a magnetic field, such as magnetic induction. The magnetic field direction detection unit 2011 can detect at least the magnetic field direction of the first magnetic body 110.

In other embodiments, the magnetic field signal detecting unit 201 may be a magnetic induction detecting unit 2012. The magnetic induction detecting unit 2012 can employ a hall sensor or other sensors capable of detecting magnetic induction and outputting different signals based on the magnitude of the magnetic induction.

During the movement of the first magnetic body 110, the magnetic field signal detection unit 201 can emit signals representing different meanings, for example, a first signal and a second signal, respectively, based on the difference of the detected magnetic field signals. For example, one of the first signal and the second signal is at a low level, and the other is at a high level. The control unit 210 controls the temperature detection device 1 to be powered on according to one of the first signal and the second signal, and controls the temperature detection device 1 to be powered off according to the other signal. That is, in some embodiments, the first signal is used to trigger the control unit 210 to control the temperature detecting device 1 to be turned on, and the second signal is used to trigger the control unit 210 to control the temperature detecting device 1 to be turned off. In other embodiments, the first signal is used to trigger the control unit 210 to control the temperature detecting device 1 to power off, and the second signal is used to trigger the control unit 210 to control the temperature detecting device 1 to power on. The specific control manner can be flexibly defined according to the specific structure and requirements of the temperature detection device 1.

This combination of the on/off operation of the device and the movement of the detection assembly 100 simplifies the operation structure for the user without the user having to perform the on/off operation. When the user opens the detection assembly 100, the on-off operation can be completed, and the convenience of the use function is greatly improved.

Meanwhile, in order to better accommodate the temperature detecting device 1 and facilitate taking, referring to fig. 2, in some embodiments, the detecting assembly 100 has a first attaching outer wall 131 for attaching a metal material, the first magnetic body 110 is disposed inside the first attaching outer wall 131, and the magnetic attraction of the first magnetic body 110 can attract the temperature detecting device 1 to an attracted object, such as a metal material or other materials capable of being magnetically attracted. The metallic material may be a metal housing or other metallic component of other devices.

This first magnetic substance 110 has a plurality of functions, and the user both accessible changes the position of first magnetic substance 110, if rotate detection subassembly 100, triggers the device switch on and off, and this first magnetic substance 110 can also be used as the magnetism portion of inhaling of device in addition, does not set up the condition of other magnetic substances, also can adsorb on metal material, can make the device structure compacter, is favorable to the miniaturized design of device.

In general, in order to increase the magnetic attraction of the first magnetic body 110 at the first attached outer wall 131, the magnetic attraction of the output may be increased by increasing parameters of the volume, the magnetic pole area, the magnetic body thickness, the magnetic body volume, and the like of the first magnetic body 110.

Referring to fig. 4 to 10, in some embodiments, the detecting assembly 100 is rotatably connected to the device body 200, and the first magnetic body 110 is disposed around the rotation axis a1 of the detecting assembly 100, so that the first magnetic body 110 can fully utilize the rotation space to enlarge the radial area and the overall volume of the first magnetic body 110, so that the outward magnetic attraction of the whole device is larger, the device can be magnetically adsorbed on other objects, and the temperature detecting device 1 can be more easily stored and taken. Moreover, when the radial area of the first magnetic element 110 is increased, the thickness thereof can be made thinner, so as not to increase the overall thickness (the thickness along the rotation axis a 1) of the detecting assembly 100, thereby being beneficial to the thinning of the whole temperature detecting device 1.

Referring to fig. 5 to 10, in some embodiments, the detecting unit 100 is rotatably connected to the apparatus body 200, and the first magnetic body 110 is arranged in a ring structure around the circumferential direction of the rotation axis a1, and the ring structure can utilize the rotation space as much as possible, so that the radial area of the first magnetic body 110 is made as large as possible.

Referring to fig. 5 and 6, in this embodiment, the first magnetic body 110 may have an escape hole at a middle portion thereof for installing other components, such as a screw for fixing a fixing cover 133 (described in detail below) therethrough.

Referring to fig. 7-10, in these embodiments, the first magnetic body 110 may further have a notch 114 besides having an avoiding hole in the middle, and the notch 114 may be used for a connection cable 122 connected to the temperature detection unit 123 to pass through.

Of course, in some other embodiments, the gap 114 may be replaced by a groove formed on the first magnetic body 110, or the ring structure may be a closed structure without the gap 114. In other embodiments, the annular structure may be replaced with a disk structure, so as to further enlarge the radial area of the first magnetic body 110. When the radial area is larger, the thickness of the first magnetic member 110 can be thinner on the premise of satisfying the magnetic attraction function, so that the space occupied by the first magnetic member 110 in the axial direction (i.e., the direction of the rotation axis a 1) can be saved.

In some embodiments, the detecting assembly 100 is rotatably connected to the device body 200, and the central angle formed by the first magnetic body 110 around the rotation axis a1 is larger than or equal to 270 °, so as to ensure that the first magnetic body 110 can provide an outward magnetic attraction force within the coverage range of the central angle.

Further, referring to fig. 3, in some embodiments, the first attached outer wall 131 is perpendicular to the rotation axis a1, so that the magnetic induction lines of the first magnetic body 110 can better act on the outer side of the first attached outer wall 131, and the metal material can be more easily adsorbed.

In some embodiments, as shown in fig. 3, the magnetizing directions of the first magnetic body 110 are all arranged along the axial direction thereof. The axial direction of the first magnetic body 110 is the rotation axis a1 of the detecting assembly 100, and the rotation axis a1 passes through the first attached outer wall 131. All set up along its axial through the direction of magnetizing with first magnetic substance 110, can improve the magnetic attraction that first magnetic substance 110 acted on first attached outer wall 131 department to improve magnetic attraction, make temperature detecting device 1 can more firm magnetism inhale to metal material on.

In some embodiments, the first attached outer wall 131 is perpendicular to the rotation axis a1, and the magnetizing direction of the first magnetic body 110 may be perpendicular to the first attached outer wall 131, so as to further increase the magnetic attraction of the first magnetic body 110 acting on the first attached outer wall 131. Of course, in some embodiments, the first attached outer wall 131 may have other non-perpendicular angles with the rotation axis a1, or may be parallel to the first attached outer wall 131.

Further, in some embodiments, the relative movement between the detecting component 100 and the device main body 200 is not limited, and in this case, the temperature detecting device 1 can achieve the magnetic attraction function of the whole device only through the first magnetic body 110, which of course requires that the first magnetic body 110 has a sufficiently large magnetic attraction force. In other embodiments of the present application, the magnetic attraction force to the outside of the entire device can also be improved by increasing the number of the magnetic bodies. In some embodiments, referring to fig. 11, 13 and 14, at least one of the probe assembly 100 and the device body 200 is further provided with a second magnetic body 261, and the second magnetic body 261 is separately provided from the first magnetic body 110 to adsorb metal materials from different positions of the temperature probe device 1.

The second magnetic member 261 may be provided in the probe unit 100 together with the first magnetic member 110, may be provided in the apparatus main body 200, or may be provided in each of the probe unit 100 and the apparatus main body 200 with the second magnetic member 261. In these embodiments, the magnetic attraction force of the whole device to the outside is increased by increasing the number of the magnetic bodies, and the magnetic attraction force requirement of the first magnetic body 110 can be reduced, so that it can be made smaller to save space.

Referring to fig. 11-14, in some embodiments, the second magnetic member 261 is disposed on the device body 200, and the first magnetic member 110 and the second magnetic member 261 are magnetically attracted to the metal material from different positions of the detecting assembly 100 and the device body 200, respectively, so as to increase the reliability of the magnetic attraction. When the magnetic attraction device is magnetically attracted to other equipment, the detection assembly 100 and the device main body 200 are both fixed in a magnetic attraction manner, so that a certain constraint force is exerted on the relative positions of the detection assembly 100 and the device main body 200, and the situation that the detection assembly 100 moves relative to the device main body 200 due to mistaken collision, and the temperature detection device 1 is mistakenly started can be prevented. Certainly, the restraining force of the magnetic attraction force on the detection assembly 100 and the device main body 200 is not too large, and when the user really wants to start the device, even if the temperature detection device 1 is magnetically attracted to other devices, the user can actively drive the detection assembly 100 to move by applying a certain external force to start the device, and the use of starting and stopping the device is not influenced.

Referring to fig. 11 and 13, in some embodiments, the device body 200 has a body case 230, the body case 230 has a second attached outer wall 234, and the second magnetic body 261 is located inside the second attached outer wall 234, so that the second attached outer wall 234 can be attached to the adsorbed object under the action of the second magnetic body 261.

Further, since the magnetic field signal detection unit 201 triggers the on/off operation based on the detected magnetic field signal, in some embodiments, in order to avoid the influence of the magnetic field of the second magnetic body 261 on the magnetic field signal detection unit 201, the second magnetic body 261 and the first magnetic body 110 may be oppositely disposed on two sides of the magnetic field signal detection unit 201. In order to reduce the influence on the magnetic field signal detection unit 201, a magnetic field shielding structure may be provided between the magnetic field signal detection unit 201 and/or the second magnetic body 261, and in this case, the second magnetic body 261 does not have to be provided apart from the magnetic field signal detection unit 201.

Referring to fig. 4 to 11, in some embodiments, the magnetic field signal detecting unit 201 is disposed on the control unit 210, and the first magnetic element 110 and the second magnetic element 261 are disposed on two sides of the control unit 210 respectively and oppositely. Of course, in other embodiments, the first magnetic body 110 and the second magnetic body 261 may be distributed in other forms, for example, distributed on the same side or adjacent sides of the control unit 210.

Referring to fig. 11, in some embodiments, the temperature detecting device 1 is a strip structure, and the first magnetic body 110 and the second magnetic body 261 are respectively located at two ends of the temperature detecting device 1 in the length direction, so as to fully utilize the length space of the temperature detecting device 1, and lengthen the distance between the second magnetic body 261 and the magnetic field signal detecting unit 201 relative to the first magnetic body 110, thereby reducing the influence of the second magnetic body 261 on the magnetic field signal detecting unit 201.

Further, in order to make the influence of the second magnetic body 261 on the magnetic field signal detection unit 201 smaller than the influence of the first magnetic body 110 on the magnetic field signal detection unit 201 as much as possible, in some embodiments, the distance between the second magnetic body 261 and the magnetic field signal detection unit 201 is larger than the distance between the first magnetic body 110 and the magnetic field signal detection unit 201.

From another perspective, in order to make the influence of the second magnetic body 261 on the magnetic field signal detection unit 201 smaller than the influence of the first magnetic body 110 on the magnetic field signal detection unit 201 as much as possible, in some embodiments, the magnetic field signal applied to the magnetic field signal detection unit 201 by the second magnetic body 261 is smaller than the magnetic field signal applied to the magnetic field signal detection unit 201 by the first magnetic body 110.

In order to ensure that the second magnetic body 261 does not affect the on/off operation of the magnetic field signal detection unit 201, in some embodiments, the magnetic field signal applied to the magnetic field signal detection unit 201 by the second magnetic body 261 is smaller than the magnetic field signal for triggering the control unit 210 to turn on and/or turn off, so that even if the magnetic field signal detection unit 201 can detect the magnetic field signal of the second magnetic body 261, the magnetic field signal does not trigger the magnetic field signal detection unit 201 to send out the on and/or off signal.

In terms of quantization, in some embodiments, the distance between the first magnetic body 110 and the second magnetic body 261 is not less than 35mm, for example, the distance between the first magnetic body 110 and the second magnetic body 261 is not less than 65mm, such as 70mm.

In some embodiments, the control unit 210 has an inductance element thereon, and therefore, an orthogonal projection of the first magnetic element 110 on the plane where the control unit 210 is located may be partially overlapped with or separated from the control unit 210, and/or an orthogonal projection of the second magnetic element 261 on the plane where the control unit 210 is located may be partially overlapped with or separated from the control unit 210, which aims to reduce an influence of the first magnetic element 110 and the second magnetic element 261 on the inductance element.

Of course, in some embodiments, the orthographic projection of the first magnetic element 110 and/or the second magnetic element 261 on the plane where the control unit 210 is located may also be completely overlapped with the control unit 210, and the influence on the inductance element is reduced by additionally providing a magnetic field shielding structure.

Further, referring to fig. 11 and 13, in some embodiments, the device body 200 has a power supply module 270, the power supply module 270 is located at one side of the control unit 210, and the second magnetic body 261 is located between the power supply module 270 and the second attached outer wall 234, so as to fully utilize the aperture between the power supply module 270 and the second attached outer wall 234, and reduce the thickness of the device body 200 as much as possible. The thickness of the device body 200 is the dimension in the vertical direction in the posture shown in fig. 11.

The power supply module 270 may be at least one of a rechargeable battery module, an external power supply module for wired connection with an external power supply, and a battery compartment module for mounting a disposable battery. Referring to fig. 11 and 13, in some embodiments, the power supply module 270 is a battery compartment module, which includes a battery compartment and a battery docking circuit, and the battery docking circuit is electrically connected to the control unit 210 to supply power to the electric components. The main body case 230 has a detachable battery cover 235, the battery cover 235 may cover the battery compartment, the battery cover 235 has an accommodation cavity toward the inside of the battery compartment, and the second magnetic substance 261 is installed in the accommodation cavity, so that the second magnetic substance 261 is accommodated by the accommodation cavity without providing an installation space for the second magnetic substance 261. At this time, at least a portion of the second attached outer wall 234 is formed by an outer wall of the battery cover 235, that is, the outer wall of the battery cover 235 may serve as the entire second attached outer wall 234, or may form the second attached outer wall 234 together with other components (e.g., other portions of the main body case 230).

Referring to fig. 13 and 14, in some embodiments, in order to fix the second magnetic body 261 to the battery cover 235, a buckle 2351 may be disposed on an inner side of the battery cover 235, and the second magnetic body 261 may be fixed between the buckle cover 262 and the battery cover 235 by the buckle 2351 via the buckle cover 262. Of course, in other embodiments, the snap-fit cover 262 can be fixed to the battery cover 235 by other means, such as welding, screwing, bonding, etc.

In addition, in some embodiments, the second magnetic body 261 can also be directly fixed to the battery cover 235 or other parts of the device body 200 by means of a snap 2351, welding, adhesion, screw fixation, or the like.

Further, in order to improve the magnetic attraction of the second magnetic body 261 acting on the second attached outer wall 234, in some embodiments, the magnetizing direction of the second magnetic body 261 is perpendicular to the second attached outer wall 234, that is, the N pole or S pole of the second magnetic body 261 is perpendicular to the plane of the second attached outer wall 234. When the second attached outer wall 234 is a non-planar structure, as shown in fig. 13, the plane of the second attached outer wall 234 is a section of the second attached outer wall 234.

From another perspective, in an embodiment, the ratio a of the total volume of the magnetic bodies (e.g. the volume of the first magnetic body 110, or the volume of the first magnetic body 110 plus the second magnetic body 261) on the detection assembly 100 to the weight of the temperature detection device 1 is: 4.0mm ³ /g≤a≤23.0mm ³ The ratio can ensure that the temperature detection device 1 can be stably adsorbed on a metal material, and the temperature detection device 1 is prevented from falling off from an adsorbed object due to overlarge weight. In some embodiments, the total magnetic force of the first magnetic element 110 or the total magnetic force of the first magnetic element 110 and the second magnetic element 261 can be 6000Gs or less, and the total volume of the first magnetic element 110 or the total volume of the first magnetic element 110 and the second magnetic element 261 can be 500-1950mm3. The total weight of the temperature detection device may be 87-120g. In some embodiments, the magnetic force of the first magnetic body 110 may be less than or equal to 3000Gs, and the volume thereof may be 500-1500mm3. In some embodiments, the magnetic force of the second magnetic body 261 may be 1000-3000Gs, and the volume thereof may be 150-450mm3.

On the other hand, besides the above-mentioned increase of the magnetic attraction force by adding the second magnetic body 261, so as to ensure that the temperature detection device 1 can be more stably adsorbed to other devices, in some embodiments, the stability of adsorption can be further improved by increasing the friction force between the temperature detection device 1 and the adsorbed object.

Referring to fig. 15, in some embodiments, at least one of the probe assembly 100 and the device body 200 has an anti-slip portion 280 for increasing friction with a metal material. The slip prevention part 280 has a rough or rugged contact surface 281, and the contact surface 281 is used to contact with an object to be adsorbed. The slip prevention part 280 may be implemented using a material or structure generally used for increasing friction, for example, by silicon or other materials having a rough surface.

Referring to fig. 15, in some embodiments, the device body 200 has anti-slip parts 280, and the anti-slip parts 280 and the first magnetic body 110 are located at two ends of the temperature detecting device 1. When the first magnetic substance 110 is adsorbed to the object to be adsorbed, the anti-slip part 280 may be attached to the object to be adsorbed, thereby increasing a frictional force with the object to be adsorbed. In addition, the anti-slip part 280 may be disposed on the probe assembly 100.

In the embodiment shown in fig. 15, the anti-slip part 280 is protruded on the battery cover 235. In other embodiments, the anti-slip part 280 may be installed at other positions of the main body case 230.

Of course, the contact surface 281 of the slip prevention part 280 may be used as the first attached outer wall 131 and/or the second attached outer wall 234, that is, the contact surface 281 of the slip prevention part 280 may be located outside the first magnetic body 110 and/or the second magnetic body 261, and may be more closely attached to the object to be adsorbed by the magnetic attraction force of the first magnetic body 110 and/or the second magnetic body 261.

Further, the triggering of the magnetic field signal detection unit 201 by the first magnetic body 110 may be implemented in various ways.

Referring to fig. 5 to 8, in some embodiments, the first magnetic body 110 has a first magnetic part 111 and a second magnetic part 112 with opposite magnetic poles. The magnetic field signal detecting unit 201 is a magnetic field direction detecting unit 2011, and the magnetic field direction detecting unit 2011 is disposed at one side of the first magnetic body 110 and configured to detect magnetic field signals of the first magnetic part 111 and the second magnetic part 112, where the magnetic field signals at least include a magnetic field direction.

The magnetic field direction detection unit 2011 issues a first signal and a second signal based on the detection result of the magnetic field signals of the first magnetic part 111 and the second magnetic part 112 during the movement of the first magnetic part 111 and the second magnetic part 112; the control unit 210 controls the temperature detection device 1 to be powered on according to one of the first signal and the second signal, and controls the temperature detection device 1 to be powered off according to the other signal. When the magnetic field direction detecting unit 2011 sends the first signal and the second signal, the magnetic field direction detecting unit is added to detect the magnetic field directions of the first magnetic part 111 and the second magnetic part 112, so that the situation of false triggering is reduced, and the on/off of the device is more reliable. In some embodiments, even if the first magnetic substance 110 with other magnetic conductive material or other position is detected by the magnetic field direction detection unit 2011, the magnetic field direction detection unit 2011 can obtain a more accurate on/off signal through detection of the magnetic field direction.

The first magnetic part 111 and the second magnetic part 112 may be different regions of the same magnetic member, and in some embodiments, two regions are divided from one integrated first magnetic body 110 for magnetizing in different directions, so as to form the first magnetic part 111 and the second magnetic part 112 with different magnetic poles. Alternatively, the first magnetic part 111 and the second magnetic part 112 are two independent magnetic members, i.e. the first magnetic part 111 and the second magnetic part 112 are two magnetic members separately manufactured, such as two separate magnets, and in this case, the two magnetic members are collectively referred to as the first magnetic body 110.

The first and second

magnetic parts

111 and 112 have different magnetizing directions, that is, so that when the first and second

magnetic parts

111 and 112 are mounted in the probe assembly 100, the N-pole and S-pole directions thereof are different, so that the magnetic field direction detection unit 2011 can distinguish the first and second

magnetic parts

111 and 112 according to the magnetic field direction.

Of course, in order to form a difference of the obvious magnetic field directions, in some embodiments, the magnetic pole directions of the first magnetic part 111 and the second magnetic part 112 may be completely opposite, that is, the magnetizing directions of the first magnetic part 111 and the second magnetic part 112 are opposite, and the N pole and the S pole thereof are just completely opposite, so that the magnetic field direction detecting unit 2011 can distinguish the first magnetic part 111 and the second magnetic part 112 according to the magnetic field directions more accurately.

When the magnetic field directions of the first magnetic part 111 and the second magnetic part 112 are different, the magnetic field direction detecting unit 2011 sends out a first signal when the magnetic field direction detecting unit 2011 detects the magnetic field signal of the first magnetic part 111 and the magnetic induction intensity of the first magnetic part 111 meets a first set range. When the magnetic field direction detection unit 2011 detects the magnetic field signal of the second magnetic part 112 and the magnetic induction intensity detected by the second magnetic part 112 satisfies a second set range, the magnetic field direction detection unit 2011 sends out a second signal.

The first setting range and the second setting range are generally determined by the setting of the magnetic-field direction detection unit 2011 itself, and the first setting range and the second setting range are different between the magnetic-field direction detection units 2011 of different principles or specifications. In some embodiments, the magnetic field direction detection unit 2011 is a magnetic tunnel sensor, and the reference value of the first setting range of the magnetic field direction detection unit 202 is B _OP The B is _OP Is positive, its Gaussian value is 5Gs or 17Gs, i.e. B _OP And +5Gs or +17Gs, when the detected magnetic induction of the first magnetic body 111 is greater than or equal to +5Gs or +17Gs, such as the detected magnetic induction of the first magnetic body 111 is +6Gs or +18Gs, which means that the first setting range is satisfied, the magnetic field direction detecting unit 202 sends out the first signal. The reference value of the second setting range is B _RP With Gauss values of either 5Gs or 17Gs, i.e. B _RP And-5 Gs or-17 Gs, when the detected magnetic induction of the second magnetic body 261 is less than or equal to-5 Gs or-17 Gs, for example, the detected magnetic induction of the second magnetic body 261 is-6 Gs or-18 Gs, which means that the second set range is satisfied, the magnetic field direction detecting unit 202 sends out the second signal. When the magnetic induction intensity to be detected is greater than B _OP Or less than B _RP Then, the magnetic induction intensity change does not affect the triggering condition of the magnetic field direction detection unit 202 until the next time the magnetic field direction detection unit is triggered again. Wherein the "+" and "-" represent B _OP And B _RP The corresponding magnetic field directions are different.

Wherein, except for the directionIn contrast, B _OP And B _RP The values of (c) may be equal or different. The B is _OP And B _RP The smaller the gaussian value of (a), the higher the sensitivity. Generally, when the magnetic induction to be detected is greater than B _OP Then, a low level is outputted, and the temperature detection device 1 is started and is smaller than B _RP At that time, a high level is output and the temperature detection device 1 is turned off. Of course, it is understood that, by changing the control logic, in some embodiments, when the high level is output, the temperature detection device 1 is powered on, and when the low level is output, the temperature detection device 1 is powered off.

Compared with the scheme of controlling the startup and shutdown by separately comparing and detecting the magnitude of the magnetic induction intensity, when the judgment of the magnetic field direction is added, the B _OP And B _RP The gaussian value of (c) is preferably smaller, making the magnetic field direction detection unit 2011 more sensitive. B is _OP And B _RP The smaller the gauss value of the first magnetic part 111 and the second magnetic part 112, the smaller the difference between the motions of the first magnetic part 111 and the second magnetic part 112 triggering the power-on and the power-off, and in some embodiments, in the embodiment where the detection assembly 100 is rotatably connected to the apparatus body 200, when B is _OP Is +5 and B _RP At-5, the probe assembly 100 may be turned on by more than 20 degrees from the initial position, providing a greater effective use angle for the probe assembly 100. Moreover, after the determination of the magnetic field direction is added, the on/off triggering is more accurate and reliable, and the on/off can be accurately and reliably controlled even under the condition that the surrounding magnetic conductive material and other first magnetic bodies 110 are applied to the magnetic field intensity or the magnetic induction intensity.

In some embodiments, the detecting assembly 100 is rotatably connected to the apparatus body 200, and the first magnetic part 111 and the second magnetic part 112 are disposed around the rotation axis a1 of the detecting assembly 100. In these embodiments, the first and second

magnetic parts

111 and 112 move around the rotation axis a1 with the rotation of the detection assembly 100. The magnetic field direction detecting unit 2011 is disposed at one side of the rotation tracks of the first magnetic part 111 and the second magnetic part 112, and is used for detecting the magnetic field signals of the first magnetic part 111 and the second magnetic part 112.

Of course, in other embodiments, the first magnetic part 111 and the second magnetic part 112 may also move in other manners relative to the apparatus main body 200, such as the aforementioned translation manner, and the magnetic field direction detection unit 2011 is disposed at one side of the translation path of the first magnetic part 111 and the second magnetic part 112.

When the first magnetic part 111 and the second magnetic part 112 are adopted, the device is provided with the first magnetic part 111 and the second magnetic part 112 at least, the area and the whole volume of the first magnetic body 110 are enlarged, the outward magnetic attraction of the whole device is larger, the device can be magnetically adsorbed on other articles, and the temperature detection device 1 is easier to store and take.

In particular, when the first and second

magnetic parts

111 and 112 are disposed around the rotation axis a1, the entire first magnetic body 110 increases in radial area and overall volume. Although the magnetic field directions are different from each other, the first magnetic part 111 and the second magnetic part 112 can both attract metal materials in the outward direction along the rotation axis a1, so that the device can be attracted to other articles magnetically, and the temperature detection device 1 can be stored and taken out more easily.

In other embodiments that the first magnetic body 110 is used to trigger the magnetic field signal detection unit 201, the magnetic field signal detection unit 201 is a magnetic induction detection unit 2012. The magnetic induction detecting unit 2012 can employ a hall sensor or other sensors capable of detecting magnetic induction and outputting different signals based on the magnitude of the magnetic induction.

Referring to fig. 9 and 10, in some embodiments, the first magnetic body 110 has a notch 114 (the notch 114 may be replaced by a groove recessed along the axial direction of the first magnetic body 110). The gap 114 or the groove has a magnetic induction different from that of the other parts of the first magnetic body 110, and can be detected by the magnetic induction detection unit 2012. The magnetic induction detecting unit 2012 is disposed at one side of the moving track of the first magnetic body 110 for detecting the magnetic field signal of the first magnetic body 110. When the magnetic induction intensity detection unit 2012 detects that the magnetic induction intensity of the first magnetic body 110 satisfies the first set range, a first signal is sent out; when the magnetic induction detection unit 2012 detects that the magnetic induction of the first magnetic body 110 satisfies the second setting range, a second signal is sent out. The reference value of the first set range is usually larger than the reference value of the second set range. . The control unit 210 controls the temperature detection device 1 to be powered on according to one of the first signal and the second signal, and controls the temperature detection device 1 to be powered off according to the other signal. The first and second signals are the same as before.

In the embodiment of detecting by using the magnetic induction detecting unit 2012, the first setting range and the second setting range generally depend on the setting of the magnetic induction detecting unit 2012 itself, and the first setting range and the second setting range are different between the magnetic induction detecting units 2012 of different principles or specifications. In one embodiment, the magnetic induction detection unit 2012 is a hall sensor, and the reference value of the first setting range of the magnetic induction detection unit 203 is B _OP B of the _OP The gauss value of (d) is about 30Gs, in some embodiments, 32Gs, and when the detected magnetic induction of the third magnetic body 113 is equal to or greater than 32Gs, which means that the first setting range is satisfied, the magnetic induction detection unit 203 sends out the first signal. The reference value of the second setting range is B _RP The gauss value is about 20Gs, in some embodiments 24Gs, and when the detected magnetic induction of the third magnetic body 113 is less than or equal to 24Gs, which means that the second setting range is satisfied, the magnetic induction detection unit 203 sends out the second signal. When the magnetic induction intensity to be detected is greater than B _OP Or less than B _RP Then, the magnetic induction change does not affect the triggering condition of the magnetic induction detection unit 203 until the next time the magnetic induction detection unit is triggered again.

In some embodiments, during the opening of the detection assembly 100, when the magnetic induction detection unit 2012 detects a magnetic field strength greater than B _OP When the temperature detection device is started, outputting a low level, and starting the temperature detection device 1; otherwise, a high level is output and the temperature detection device 1 is turned off. In the process of folding the detecting assembly 100, when the magnetic induction detecting unit 2012 detects that the magnetic field strength is less than B _RP When the temperature is detected, outputting a high level, and shutting down the temperature detection device 1; otherwise, a low level is output and the temperature detection device 1 is turned on. Of course, it will be appreciated that the control logic may be varied, at some pointIn the embodiment, when the high level is output, the temperature detection device 1 is turned on, and when the low level is output, the temperature detection device 1 is turned off.

In these embodiments of performing magnetic field detection by the magnetic induction detection unit 2012, the detection of the magnetic field direction may be omitted, the first magnetic part 111 and the second magnetic part 112 having different magnetic pole directions need not to be provided, and the triggering of the on/off operation can be completed only by detecting the magnetic induction of the first magnetic body 110. Moreover, the first magnetic body 110 is distributed around the rotation axis a1, so that when the first magnetic body 110 rotates, the range of the first magnetic body detected by the magnetic induction detection unit 2012 is longer, the detected area is larger, the first magnetic body is more easily detected by the magnetic induction detection unit 2012, and the reliability of the startup and shutdown is improved. Moreover, the first magnetic body 110 is arranged around the rotation axis a1, so that the area and the whole volume of the first magnetic body 110 in the radial plane are enlarged, the outward magnetic attraction force of the whole device is larger, the device can be magnetically adsorbed on other articles, and the temperature detection device 1 is easier to store and take.
