Description

Technical Field

[0001] This utility model relates to the field of temperature measuring device technology, specifically a thermos cup temperature measuring machine. Background Technology

[0002] A thermos is a water container made of ceramic or stainless steel with a vacuum layer. It has a lid that seals tightly. The vacuum insulation layer inside the thermos slows down the heat dissipation of the liquid inside, thus achieving the purpose of keeping it warm. The heat preservation ability of a thermos mainly depends on the degree of temperature isolation between the contents and the external environment. Therefore, its heat preservation performance is verified by blowing hot air into the thermos and keeping it warm for a period of time, and then measuring the temperature change between the thermos and the hot air.

[0003] Among them, the present technology authorized by announcement number CN206945590U discloses a thermos cup temperature measuring machine chassis and a water-cooled platform set in the working cavity of the chassis. The water-cooled platform is evenly distributed with hot air pipes and return air vents corresponding to the hot air pipes. The water-cooled platform has a cooling function. A support tube is installed above the water-cooled platform, and temperature sensors corresponding to the hot air pipes are evenly distributed on the support tube.

[0004] Existing thermos cup temperature measuring machines are not perfect at orienting thermos cups. During the temperature measurement process, the force of the hot air can cause the thermos cup to be misoriented, and it cannot be guaranteed that the hot air blown into each hot air pipe is evenly distributed. The efficiency is not high, which greatly affects the temperature measured by the temperature sensor and cannot effectively measure the temperature. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a thermos cup temperature measuring machine that can effectively orient the thermos cup completely, effectively and evenly distribute the hot air blown into the thermos cup, and is more convenient to use, thus effectively solving the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thermos cup temperature measuring machine, characterized in that it includes a workbench, a two-stage fixing unit, a heating unit, and a thermos cup;

[0007] Workbench: Insulated cups are evenly placed on the workbench. The top inner side of the workbench is provided with a return air chamber. The upper surface of the workbench is provided with return air holes corresponding to the positions of the insulated cups. The return air chamber is connected to the return air holes. The lower side of the return air chamber is connected to the upper end of the air duct. The lower side of the return air duct is fixedly connected to the heating unit. The top of the workbench is provided with a hot air chamber located below the return air chamber. The upper side of the hot air chamber is provided with a hot air duct that extends through the return air holes to the upper side of the workbench. The lower side of the interior of the hot air chamber is connected to the upper side of the air guide pipe. The lower side of the air guide pipe is fixedly connected to the heating unit.

[0008] Secondary fixed unit: includes a handwheel, threaded shaft, nut, fixed frame, movable frame and support column. The support column is fixedly connected to the four corners of the upper side of the worktable. The movable frame is vertically slidably connected to the upper middle part of the support column, and the fixed frame is fixed to the upper part of the support column by the nut. The lower end of the threaded shaft is rotatably connected to the upper middle part of the movable frame. The upper end of the threaded shaft is fixedly connected to the lower side of the handwheel, and the threaded shaft is threadedly connected to the threaded hole in the middle of the fixed frame.

[0009] When using, first loosen the nut to move the fixed frame and movable frame away from the support column. After they are away from the support column, place the thermos cup on the worktable. After the thermos cup is placed, install the fixed frame and movable frame on the support column. After installation, tighten the nut to limit the movement of the fixed frame. After tightening the nut, turn the handwheel to move it closer to the top of the thermos cup until it is pressed against the top of the thermos cup. Pressing it against the top of the thermos cup completes the first stage of fixation.

[0010] Furthermore, the heating unit includes a fan inlet, a blower, a base, a heat-generating box, a heat-generating box outlet duct, a temperature control knob, air filter plates, and finned heating tubes. The lower side of the return air duct is fixedly connected to one side of the fan inlet, and the other side of the fan inlet is fixedly connected to one side of the blower. The blower is fixed on the base, and the blower outlet is fixedly connected to the left side of the heat-generating box. The heat-generating box is equipped with at least three air filter plates, which divide the interior of the heat-generating box into an S-shaped air duct. Finned heating tubes are installed in the S-shaped air duct. The right side of the heat-generating box is fixedly connected to one side of the heat-generating box outlet duct, and the other side of the heat-generating box outlet duct is fixedly connected to the lower side of the air duct.

[0011] When the temperature measuring machine is running, first adjust the temperature control knob to a suitable temperature. Then, the finned heating tubes start heating to generate hot air. Then, the blower is controlled by the external switch group. The air generated by the blower is input into the heat generation box through the blower's air outlet. The air blows the hot air generated by the finned heating tubes in the heat generation box. As the hot air passes through the S-shaped air duct formed by the air filter plate inside the heat generation box and the mesh on the air filter plate, the hot air is blown into the connecting air duct. The airflow passing through the S-shaped air duct and the mesh on the air filter plate can make the heat of the airflow more even.

[0012] Furthermore, it also includes a primary fixing unit, which comprises a fixing block, a spring, an arc-shaped clamp, a semi-circular arc-shaped fixing plate, and a groove. The upper side of the workbench is provided with a groove corresponding to the bottom of the thermos cup. The top left side of the groove is fixedly connected to the semi-circular arc-shaped fixing plate. The right side of the top of the groove is provided with an arc-shaped clamp that does not contact the groove. The right side of the arc-shaped clamp is fixedly connected to the left side of the fixing block by a horizontal telescopic rod. A spring is sleeved on the telescopic rod. The lower side of the fixing block is fixedly connected to the upper side of the workbench.

[0013] The spring design allows the curved clamp to automatically adjust the distance according to the diameter of the thermos cup. When the diameter of the thermos cup is small, the spring automatically extends, causing the curved clamp to clamp the thermos cup against the inner wall of the semi-circular fixed plate. When the diameter of the thermos cup is large, the spring is compressed to adapt to the size of the thermos cup and clamp it, so as to meet the needs of detection and fixation of thermos cups of different diameters.

[0014] Furthermore, it also includes a warning light and an infrared thermometer, with the infrared thermometer located on the lower side of the movable frame and the warning light installed on the left side of the semi-circular fixed plate.

[0015] After the inner cavity of the thermos is heated, the infrared thermometer measures the temperature of the thermos. The infrared thermometer can quickly read the result. After the infrared thermometer reads the result, the warning light on the left side of the thermos with a high temperature will flash, so that the user can identify the unqualified thermos by the position of the flashing warning light and remove it.

[0016] Furthermore, it also includes a semi-circular bushing and an insulation pipe, wherein the insulation pipe is fixedly sleeved to the outer periphery of the air inlet pipe by bolts of the semi-circular bushing.

[0017] The insulation pipe installed on the outer periphery of the air inlet further maintains the temperature of the hot air, so that the inside of the thermos can be quickly filled with hot air.

[0018] Furthermore, it also includes a workbench cover, which is located above the secondary fixing unit. The workbench cover is used to ensure that the temperature measuring machine is in good working condition when it is working, eliminating interference from indoor and outdoor temperatures.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This thermos cup temperature measuring machine has the following advantages:

[0020] 1. This thermos cup temperature measuring machine can be driven by a handwheel to rotate the threaded shaft. The rotation of the threaded shaft drives the movable frame to move. After the movable frame moves, it contacts the upper side of the thermos cup to achieve the first-level fixation. Then, through the cooperation of the fixing block, spring and arc-shaped clamp, the thermos cup is further fixed to achieve the second-level fixation effect, making the thermos cup more stable.

[0021] 2. When the hot air is delivered, the adjustment knob is first adjusted to a suitable temperature. Then the finned heating tube starts to heat and generate hot air. As the hot air is blown into the air duct through the S-shaped air duct formed by the baffle plate inside the heat generation box, the air force can make the heat of the air force more uniform through the S-shaped air duct, which can effectively heat the gas and achieve a higher heating effect.

[0022] 3. This thermos cup temperature measuring machine can perfectly orient the thermos cup in both longitudinal and lateral movements. During the temperature measurement process, the hot air force can make the thermos cup completely oriented, and can ensure that the hot air blown into each hot air pipe is evenly distributed. It has high efficiency and can effectively measure temperature. Attached Figure Description

[0031] Secondary fixed unit 2: includes handwheel 21, threaded shaft 22, nut 23, fixed frame 24, movable frame 25 and support column 26. The support column 26 is fixedly connected to the four corners of the upper side of the workbench 1. The movable frame 25 is vertically slidably connected to the upper middle part of the support column 26, and the fixed frame 24 is fixed to the upper part of the support column 26 by the nut 23.

The lower end of the threaded shaft 22 is fixedly connected to the lower side of the handwheel 21, and the threaded shaft 22 is threadedly connected to the threaded hole in the middle of the fixed frame 24.

[0032] When using, first loosen nut 23 to move the fixed frame 24 and movable frame 25 away from the support column 26. After moving away from the support column 26, place the thermos cup 7 on the workbench 1. After the thermos cup 7 is placed, install the fixed frame 24 and movable frame 25 on the support column 26. After installation, tighten nut 23 to limit the movement of the fixed frame 24. After tightening nut 23, turn handwheel 21 to move it towards the top of the thermos cup 7 until it is pressed against the top of the thermos cup 7. Pressing it against the top of the thermos cup 7 completes the first stage of fixation.

[0033] The heating unit 3 includes a fan inlet 32, a blower 33, a base 34, a heat-generating box 35, a heat-generating box outlet duct 36, a temperature control knob 37, an air filter plate 310, and a finned heating tube 311. The lower side of the return air duct 10 is fixedly connected to one side of the fan inlet 32, and the other side of the fan inlet 32 ​​is fixedly connected to one side of the blower 33. The blower 33 is fixed on the base 34, and the outlet of the blower 33 is fixedly connected to the left side of the heat-generating box 35. The heat-generating box 35 is provided with at least three air filter plates 310, which divide the interior of the heat-generating box 35 into an S-shaped air duct.

The right side of the heat-generating box 35 is fixedly connected to one side of the heat-generating box outlet duct 36, and the other side of the heat-generating box outlet duct 36 is fixedly connected to the lower side of the air duct 18.

[0034] When the temperature measuring machine is running, first adjust the temperature control knob 37 to a suitable temperature. Then, the finned heating tube 311 starts to heat and generate hot air. Then, the blower 33 is controlled by the external switch group. The air generated by the blower 33 is input into the heat generation box 35 through the air outlet of the blower 33. The air blows the hot air generated by the finned heating tube 311 in the heat generation box 35. As the hot air passes through the S-shaped air duct formed by the air filter plate 310 inside the heat generation box 35 and the mesh on the air filter plate 310, the hot air is blown into the connecting air duct 18. The air passing through the S-shaped air duct and the mesh on the air filter plate 310 can make the heat of the air more uniform.

[0035] It also includes a primary fixing unit 4, which includes a fixing block 41, a spring 42, an arc-shaped clamp 43, a semi-circular arc-shaped fixing plate 44, and a groove 45. The upper side of the workbench 1 is provided with a groove 45 corresponding to the bottom of the thermos cup 7. The semi-circular arc-shaped fixing plate 44 is fixedly connected to the top left side of the groove 45. The right side of the top of the groove 45 is provided with an arc-shaped clamp 43 that does not contact the groove 45. The right side of the arc-shaped clamp 43 is fixedly connected to the left side of the fixing block 41 through a horizontal telescopic rod. The spring 42 is sleeved on the telescopic rod. The lower side of the fixing block 41 is fixedly connected to the upper side of the workbench 1.

[0036] The spring 42 allows the arc-shaped clamp 43 to automatically adjust the distance according to the different diameters of the thermos cups 7. When the diameter of the thermos cup 7 is small, the spring 42 automatically extends, causing the arc-shaped clamp 43 to clamp the thermos cup 7 against the inner wall of the semi-circular arc-shaped fixing plate 44. When the diameter of the thermos cup 7 is large, the spring 42 is compressed to adapt to the size of the thermos cup 7 and clamp it, so as to meet the needs of detection and fixation of thermos cups 7 with different diameters.

[0037] It also includes a warning light 6 and an infrared thermometer 9. The infrared thermometer 9 is located on the lower side of the movable frame 25, and the warning light 6 is installed on the left side of the semi-circular fixed plate 44.

[0038] After the inner cavity of the thermos cup 7 is heated, the infrared thermometer 9 measures the temperature of the thermos cup 7. The infrared thermometer 9 can quickly read the result. After the infrared thermometer 9 reads the result, the warning light 6 on the left side of the thermos cup with a high temperature will flash, so that the user can identify the unqualified thermos cup 7 according to the flashing position of the warning light 6 and remove it.

[0039] It also includes a semi-circular bushing 16 and an insulation pipe 17, which are fixedly sleeved on the outer periphery of the air inlet pipe 18 by bolts of the semi-circular bushing 16.

[0040] The heat insulation pipe 17 installed on the outer periphery of the air inlet pipe 18 further maintains the temperature of the hot air so that the inside of the thermos cup 7 can be quickly filled with hot air.

[0041] It also includes a workbench cover 8, which is located above the secondary fixing unit 2. The workbench cover 8 is used to ensure that the temperature measuring machine is in good working condition and to eliminate the interference of indoor and outdoor temperatures.

[0042] The working principle of the thermos cup temperature measuring machine provided by this utility model is as follows: In use, first unscrew the nut 23 to move the fixed frame 24 and movable frame 25 away from the support column 26. After moving away from the support column 26, place the thermos cup 7 in the groove 45 on the workbench 1. The spring 42 allows the arc-shaped clamping plate 43 to automatically adjust the distance according to the different diameters of the thermos cup 7. When the diameter of the thermos cup 7 is small, the spring 42 automatically extends, causing the arc-shaped clamping plate 43 to clamp the thermos cup 7 against the inner wall of the semi-circular arc-shaped fixed plate 44. When the diameter of the thermos cup 7 is large, the spring 42 is compressed to adapt to the size of the thermos cup 7 and clamp it, so as to meet the needs of testing and fixing thermos cups 7 of different diameters. After the thermos cup 7 is placed, the fixing bracket 24 and the movable bracket 25 are installed on the support column 26. After installation, the nut 23 is tightened to limit the movement of the fixing bracket 24. After the nut 23 is tightened, the handwheel 21 is turned to move it towards the upper part of the thermos cup 7 until it is pressed against the upper side of the thermos cup 7. Pressing it against the upper side of the thermos cup 7 completes the secondary fixation. After the thermos cup 7 is fixed, the workbench cover 8 is placed over the workbench 1. The workbench cover 8 is used to ensure good working condition when the temperature measuring machine is working, eliminating interference from indoor and outdoor temperatures. Then, the temperature control knob 37 is adjusted to a suitable temperature. Subsequently, the finned heating tube 311 begins to heat and generate hot air. Then, the blower 33 is controlled by the external switch group to work. The air force generated by the blower 33 is input into the heat generation box 35 through the air outlet of the blower 33. The air force blows the hot air generated by the finned heating tube 311 in the heat generation box 35. As the hot air passes through the S-shaped air duct formed by the air filter plate 310 inside the heat generation box 35 and the mesh on the air filter plate 310, the hot air is blown into the heat generation box 35. The airflow through the connecting duct 18, passing through the S-shaped air duct and the mesh on the filter plate 310, makes the heat from the airflow more even. The heat insulation pipe 17 set on the outer periphery of the connecting duct 18 further maintains the temperature of the hot air, so that the inside of the thermos cup 7 can be quickly filled with hot air. After the inner cavity of the thermos cup 7 is heated, the infrared thermometer 9 measures the temperature of the thermos cup 7. The infrared thermometer 9 can quickly read the result. After the infrared thermometer 9 reads the result, the warning light 6 on the left side of the thermos cup with a high temperature will flash, so that the user can identify the unqualified thermos cup 7 according to the flashing position of the warning light 6 and remove it, thus completing the temperature measurement of the thermos cup.

[0043] It is worth noting that the external control switch group disclosed in the above embodiments is equipped with control buttons corresponding to the blower 33 and the heat generation box 35. It is recommended that the blower 33 be a CFA series multi-blade centrifugal fan, and the heat generation box 35 be a HAM-G3A-11 heat generation box. The external control switch group controls the operation of the blower 33 using methods commonly used in the prior art.

[0044] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
