In order to be able to detect the temperature of the food material or the food material processing medium, such as water, during cooking and for ease of use, the present application provides a hand-held temperature probe 10 for food material cooking (hereinafter simply referred to as temperature probe 10). As shown in fig. 2, fig. 2 is a block diagram of a temperature probe 10 provided herein.
The temperature probe 10 includes a probe assembly 11 and a body 12, the probe assembly 11 being coupled to the body 12. Wherein probe assembly 11 may be directly or indirectly attached to body 12, and probe assembly 11 may be fixedly attached to body 12, such as by clamping, bonding, threading, etc. The probe assembly 11 may be movably connected to the main body 12, for example, rotationally connected, or the probe assembly 11 may move in a plane relative to the main body 12, and the connection manner of the probe assembly 11 and the main body 12 may be other connection manners as will occur to those skilled in the art, and is not limited to the above connection manners.
In one embodiment, the body 12 includes a control unit, which may be a circuit board with control circuitry, or other structure or circuitry capable of controlling, or a combination of both. The control unit can be used for controlling the opening and closing of the handheld temperature probe 10, and the control unit is also electrically connected with the probe assembly 11, signals detected by the probe assembly 11 can be transmitted to the control unit, and the control unit processes the signals to obtain a temperature detection result, so that the temperature probe 10 realizes temperature detection.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a probe assembly 11 provided in the present application. In one embodiment, probe assembly 11 includes a tube 111, a thermocouple 112, and a first thermally conductive material 113.
The tube 111 is a metal tube having a receiving cavity 1111 for protecting the thermocouple 112 from damage. The tube 111 may be made of a metal having a high thermal conductivity, such as platinum, aluminum, copper, nickel, iron, stainless steel, or an alloy thereof. In order to make the measured temperature more accurate, the wall thickness of the tube 111 may be reduced, and the tube 111 having a smaller inner diameter may be used, thereby improving the hysteresis of the thermocouple 112. In the embodiment of fig. 3, the wall thickness of the tube 111 is 0.2mm, but in other embodiments, other wall thicknesses are possible.
The thermocouple 112 may include a first thermally conductive wire 1121 and a second thermally conductive wire 1122 joined in a loop at both ends, and the thermocouple 112 has a working end 113a (hot end) and a reference end (cold end). When there is a temperature difference between the working end 113a and the reference end, a thermoelectric voltage is generated in the loop, and the reference end of the thermocouple 112 is electrically connected with the control power supply, so that the control unit can detect a temperature difference signal, and a temperature detection result is obtained by processing the temperature difference signal.
In addition, the thermocouple 112 may further include first and second insulating sleeves 1123 and 1124 respectively sleeved on the first and second heat conductive wires 1121 and 1122, and the working and reference ends 113a and 113 b of the thermocouple 112 are disposed outside the first and second insulating sleeves 1123 and 1124. By providing the first insulating jacket 1123 and the second insulating jacket 1124, the first insulating jacket 1123 and the second insulating jacket 1124 can avoid mutual contact between the first heat conductive wire 1121 and the second heat conductive wire 1122, and can prevent the first heat conductive wire 1121 and the second heat conductive wire 1122 from being damaged, thereby improving the service life of the thermocouple 112.
A part of the thermocouple 112 is disposed in the accommodating chamber 1111, and a working end 113a of the thermocouple 112 is fixedly disposed on the tube 111 so that at least a part of the working end 113a is exposed from the tube 111, so that the working end 113a can be used for detecting temperature.
Specifically, the extension direction of the thermocouple 112 and the extension direction of the accommodation chamber 1111 may be the same or substantially the same. The central axis of the thermocouple 112 may coincide or substantially coincide with the central axis of the receiving chamber 1111, or the central axis of the thermocouple 112 may be offset from the central axis of the receiving chamber 1111.
In an embodiment, the portions of the thermocouple 112 except the working end 113a are all disposed in the accommodating cavity 1111, specifically, the first insulating sleeve 1123 and the second insulating sleeve 1124 of the thermocouple 112 are all disposed in the accommodating cavity 111, a portion of the first heat conducting wire 1121, a portion of the second heat conducting wire 1122 and the reference end are all disposed in the accommodating cavity 111, the working end 113a is disposed on the pipe body 111 and penetrates through the pipe body 111, so that at least a portion of the working end 113a is exposed from the pipe body 111, and the reference end in the pipe body 111 can be electrically connected with the control unit by providing a lead. In other embodiments, the thermocouple 112 is not limited to the above-mentioned structure and may be other structures.
The fixing manner of the working end 113a of the thermocouple 112 and the tube 111 may specifically be welding, bonding, or the like, preferably, the working end 113a and the tube 111 are fixed by welding, and the working end 113a and the tube 111 are fixed by welding, so that the stability is good and the operation is convenient.
At least part of the working end 113a is exposed from the pipe body 111, i.e., part of the working end 113a may be exposed from the pipe body 111, and the other part may be embedded in the pipe wall of the pipe body 111; or the first part of the working end 113a is exposed from the pipe body 111, the second part is embedded in the pipe wall of the pipe body 111, and the third part is positioned in the accommodating cavity 1111; or all of the working end 113a is exposed from the pipe body 111. Here, exposing may mean that at least a portion of the working end 113a is exposed from the pipe body 111 and does not protrude from the pipe body 111, or that at least a portion of the working end 113a protrudes from the pipe body 111 and is exposed.
Since the working end 221 of the thermocouple 22 and the object to be measured (fig. 1) have at least the thickness of the tube 21 and the distance between the working end 221 of the thermocouple 22 and the object to be measured, even if the tube 21 and the heat conducting material 23 are made of materials with high heat conductivity coefficients, the temperature between the working end 221 and the object to be measured cannot be prevented from having hysteresis, so that the response time of the temperature probe 20 is long.
In use, the working end 113a of the thermocouple 112 exposed from the tube 111 can directly contact with an object to be measured, and compared with the structure that the working end 113a contacts with the object to be measured indirectly, the temperature probe 10 has shorter response time, and effectively solves the problem of temperature hysteresis of the detection of the temperature probe 10.
The first heat conductive material 113 is filled in the accommodating cavity 1111, and the first heat conductive material 113 covers at least the connection portion between the working end 113a and the pipe body 111. When the working end 113a is welded to the pipe body 111, the first heat-conducting material 113 covers at least the welding point between the working end 113a and the pipe body 111.
Because the temperature of the air is relatively slow, and particularly the air which is not easy to flow in the pipe body 111 is a poor conductor of heat, the first heat conduction material 113 covers the joint of the working pipe and the pipe body 111, so that the air near the joint can be replaced by the heat conduction material with good heat conductivity, the response time of the temperature probe 10 reaching the target temperature can be prevented from being prolonged due to heat absorption of the air near the joint, and the response time of the temperature probe 10 can be further reduced.
In some embodiments, referring to fig. 3, the receiving chamber 1111 includes a first chamber 1112 extending rearwardly from a front end (left end as shown) thereof, in this application, the front end is the end proximate to the working end 113a of the thermocouple 112 and the rear end is the end proximate to the reference end of the thermocouple 112.
The thermocouple 112 is disposed through the first cavity 1112, the working end 113a of the thermocouple 112 penetrates through the cavity wall of the first cavity 1112, and the working end 113a of the thermocouple 112 is fixedly disposed on the cavity wall of the first cavity 1112. The radial gap a between the thermocouple 112 and the cavity wall of the first cavity 1112 is < 3mm, preferably a < 2mm, in some embodiments 0.1.ltoreq.a.ltoreq.1 mm, which may be, for example, 0.2mm, 0.375mm, 0.7mm, 1mm, etc. I.e. the position of the first cavity 1112 can be determined by the radial clearance a < 3mm.
For example, in the embodiment of fig. 3, the radial gap a of the receiving chamber 1111 from the front end c to d thereof satisfies a < 3mm, the radial gap a of the receiving chamber 1111 from d to back does not satisfy a < 3mm, and the first chamber 1112 is the space of the receiving chamber 1111 from c to d.
The radial gap between the thermocouple 112 and the cavity wall of the first cavity 1112 may be a radial gap between the outer wall of the first heat conducting wire 1121 or the second heat conducting wire 1122 and the cavity wall of the first cavity 1112, or may be a radial gap between the outer wall of the insulating sleeve 1123 outside the heat conducting wire and the cavity wall of the first cavity 1112.
The first heat conductive material 113 is filled between the wall of the first cavity 1112 and the thermocouple 112. The first heat conductive material 113 may be filled in a part of the space between the wall of the first cavity 1112 and the thermocouple 112, or the first heat conductive material 113 may be filled in the whole space between the wall of the first cavity 1112 and the thermocouple 112.
By filling the first heat conductive material 113 between the wall of the first cavity 1112 and the thermocouple 112, more air layer of the working end 113a of the thermocouple 112 toward the rear end can be replaced with a material having good heat conductivity, preventing the heat absorption of air at the rear end of the working end 113a from causing the response time of the temperature probe 10 to reach the target temperature to become long, and thus the response time of the temperature probe 10 can be further reduced.
The first heat conductive material 113 may be a material having a high heat conductivity, for example, may be heat conductive silicone grease or copper powder. Preferably, the thermal conductivity of the first thermal conductive material 113 is greater than that of the tube 111, and may be more than 10 times. The larger the thermal conductivity of the first thermal conductive material 113 with respect to the thermal conductivity of the pipe body 111, the smaller the temperature difference inside and outside the pipe body 111, and the shorter the response time.
The shape of the first cavity 1112 may be a regular shape, such as a cylinder, a prism, etc.; the shape of the first cavity 1112 may also be irregular. In one embodiment, as shown in fig. 3, the first cavity 1112 includes a first cavity 1112a and a second cavity 1112b, the first cavity 1112a is located at a front end of the first cavity 1112, the second cavity 1112b is located at a rear end of the first cavity 1112, and the first cavity 1112a is in communication with the second cavity 1112 b. The second cavity 1112b may be a cylinder, for example, a cylinder, a prism, or the like; the first cavity 1112a is shaped as a cone or hemisphere. In the embodiment of fig. 3, the second cavity 1112b is cylindrical in shape and the first cavity 1112a is conical in shape.
The working end 113a of the thermocouple 112 may be disposed through and secured to the cavity wall at the apex of the first cavity 1112a, e.g., in the embodiment of fig. 3, the thermocouple 112 passes through the first cavity 1112a and the second cavity 1112b, and the working end 113a of the thermocouple 112 is disposed through and secured to the cavity wall at the apex of the first cavity 1112a of the cone. Of course, in some embodiments, the working end 113a of the thermocouple 112 may also be disposed through and fixedly on the side wall of the first cavity 1112a, or the working end 113a of the thermocouple 112 may also be disposed through and fixedly on the side wall of the second cavity 1112 b.
In other embodiments, the shape of the first cavity 1112 may be other shapes, not limited to the above-mentioned shapes.
Further, the first heat conducting material 113 may fill the gap between the wall of the first cavity 1112 and the thermocouple 112, for example, in the embodiment of fig. 3, the first heat conducting material 113 fills the gap between the wall of the first cavity 1112a and the thermocouple 112, and the first heat conducting material 113 also fills the gap between the wall of the second cavity 1112b and the thermocouple 112. In some embodiments, please refer to fig. 5, fig. 5 is another schematic structure of the probe assembly 11 provided in the present application. The first heat conductive material 113 may fill only the gap between the cavity wall of the first cavity 1112a and the thermocouple 112. In some embodiments, the first thermally conductive material 113 may fill the gap between the cavity wall of the first cavity 1112a and the thermocouple 112, and the first thermally conductive material 113 may also fill a portion of the gap between the cavity wall of the second cavity 1112b and the thermocouple 112. In some embodiments, the first thermally conductive material 113 covers at least the junction of the working end 113a of the thermocouple 112 and the tube wall of the first cavity 1112.
In the above-mentioned scheme of the temperature probe 10, after the welding of the thermocouple 112 and the tube 111 is completed, the space in which the narrow-mouth tube 111 can operate is small due to the existence of the thermocouple 112, and it is difficult to directly inject the first heat conductive material 113 into the first cavity 1112 through the syringe. And, it is difficult to extrude the thick heat conductive material using a small-diameter syringe. Also, in the welding process, the first cavity 1112 cannot be pre-filled with the first heat conductive material 113 before welding. This is because the first heat conductive material 113 is pre-buried in the pipe body 111, which may affect the effect of the welding process, resulting in welding failure.
In view of the above problem, the present application further provides an embodiment, as shown in fig. 3, where the accommodating cavity 1111 further includes a second cavity 1113 in addition to the first cavity 1112, the first cavity 1112 is communicated with the second cavity 1113, and a front end of the second cavity 1113 is connected to a rear end of the first cavity 1112.
Referring to fig. 3 and 4, the arrow of fig. 4 indicates the direction of movement of the first thermally conductive material 113 in reverse. After the thermocouple 112 and the first cavity 1112 are fixed, the first heat-conducting material 113 can be injected into the second cavity 1113 through the injector, and as the radial clearance between the cavity wall of the second cavity 1113 and the thermocouple 112 is larger, the injector with larger pipe diameter can be selected, and the radial clearance is larger, the space in which the injector can operate is larger, the operation difficulty of injecting the first heat-conducting material 113 into the second cavity 1113 through the injector is smaller, and the influence on the thermocouple 112 in the operation process is smaller. After the first heat conducting material 113 is injected into the second cavity 1113, the first heat conducting material 113 in the second cavity 1113 is moved into the first cavity 1112 by external force, so that the first heat conducting material 113 at least covers the connection part between the working end 113a of the thermocouple 112 and the pipe wall of the first cavity 1112. The external force can be moved in a swinging, shaking, impacting, centrifuging and other modes.
In some embodiments, when the viscosity of the first thermally conductive material 113 is relatively high, for example, when the first thermally conductive material 113 is a thermally conductive silicone grease, a portion of the first thermally conductive material 113 in the second cavity 1113 moves into the first cavity 1112, and another portion of the first thermally conductive material 113 in the second cavity 1113 remains on the cavity wall of the second cavity 1113.
In some embodiments, please refer to fig. 6, fig. 6 is a schematic diagram of another structure provided in the present application. The probe assembly 11 further includes a second thermally conductive material 114, the second thermally conductive material 114 filling a gap between a cavity wall of the second cavity 1113 and the thermocouple 112, the second thermally conductive material 114 being configured to seal the first thermally conductive material 113. The second thermally conductive material 114 may fill the gap between the cavity wall of the second cavity 1113 and the thermocouple 112; for cost saving, the second heat conductive material 114 may fill only the gap at the inlet where the second cavity 1113 is connected to the first cavity 1112, so long as the first heat conductive material 113 can be sealed. In the embodiment of fig. 6, the first thermally conductive material 113 is copper powder and the second thermally conductive material 114 is thermally conductive silicone grease.
By providing the second thermally conductive material 114, the second thermally conductive material 114 can also displace air within the second cavity 1113, thereby shortening the response time of the temperature probe 10, and the second thermally conductive material 114 can seal the first thermally conductive material 113 within the first cavity 1112.
In some embodiments, probe assembly 11 may further include a seal disposed in second cavity 1113 for sealing first thermally conductive material 113, i.e., in this embodiment, the seal may seal first thermally conductive material 113 in place of second thermally conductive material 114. Specifically, the sealing member may be sleeved on the insulating sleeve 1123 of the thermocouple 112, and disposed at an inlet where the second cavity 1113 is connected to the first cavity 1112.
The foregoing description of the utility model has been presented for purposes of illustration and description, and is not intended to be limiting. Several simple deductions, modifications or substitutions may also be made by a person skilled in the art to which the utility model pertains, based on the idea of the utility model.
