Description

Technical Field

[0001] The present invention relates to a thermometer and a placement device thereof, in particular to a temperature detection device containing liquid metal gallium indium tin alloy. Background Art

[0002] Gallium indium tin alloy is an alloy composed of three elements: gallium (Ga), indium (In) and tin (Sn). Due to the common mercury thermometers, they will gradually be banned in my country due to their high toxicity and fragility. Gallium indium tin alloy is safe and non-toxic, so gallium indium tin alloy thermometers will gradually replace traditional mercury thermometers.

[0003] Since gallium-indium-tin alloy has a high melting point, if the ambient temperature is lower than the melting point of the alloy (about 12°C), the liquid alloy will solidify and need to be preheated to restore function, otherwise it cannot be used normally. In most areas, the room temperature is low in winter, which will cause the alloy inside the gallium-indium-tin alloy thermometer to solidify. Secondly, similar to traditional thermometers, gallium-indium-tin alloy thermometers use a glass shell, which can easily break if dropped or collided, requiring the fragments to be handled and may cause safety hazards. Summary of the Invention

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figure 1-6 As shown, the present invention has the following specific embodiments.

[0032] Example 1

[0033] A temperature detection device containing liquid metal gallium indium tin alloy comprises a constant temperature storage box 1 and a mercury-free thermometer 5 placed therein. The temperature sensing end of the mercury-free thermometer 5 is fixedly connected to a liquid storage bubble, and the liquid storage bubble encapsulates gallium indium tin alloy as a temperature measuring medium.

[0034] The constant temperature storage box 1 is composed of a heat-conducting inner liner 101 and a heat-insulating outer shell 102 covering the outer liner to form a composite cavity;

[0035] A vertical mounting slot 2 is provided inside the heat-conducting inner liner 101, and a loading box 4 is slidably mounted in the mounting slot 2;

[0036] Constant temperature heating rods 106 are fixed symmetrically in the heat-conducting inner container 101 and located on both sides of the mounting groove 2;

[0037] A storage slot 404 matching the shape of the mercury-free thermometer 5 is defined on the front of the loading box 4 . The mercury-free thermometer 5 is detachably accommodated in the storage slot 404 .

[0038] In this embodiment, the mercury in the existing traditional mercury thermometer is replaced with liquid metal gallium indium tin alloy. The non-toxic gallium indium tin alloy replaces the toxic mercury, which can prevent the mercury from entering the human body after the thermometer is broken and causing damage to the human body. When not in use, the mercury-free thermometer 5 is placed in the storage slot 404, and the loading box 4 is inserted completely into the installation slot 2. The thermal insulation shell 102 can isolate a certain amount of heat dissipation, and the thermal conductive inner liner 101 can conduct a certain amount of heat. Starting the constant temperature heating rod 106 can generate a certain amount of heat, which is conducted to the inside of the thermal conductive inner liner 101, thereby keeping the inside of the device in a constant temperature environment of 20 to 30 degrees Celsius, avoiding the problem of the gallium indium tin alloy inside the mercury-free thermometer 5 being overcooled and solidified, and ensuring that the mercury-free thermometer 5 can still be taken out and used directly in a cold environment.

[0039] Example 2

[0040] A fixed ear 103 is fixed on the thermal insulation shell 102, and its four corners are covered with rubber anti-collision corners 104. An observation port is coaxially provided on the front of the thermal insulation shell 102 and the heat-conducting liner 101. A transparent observation window 105 is embedded in the observation port, and the periphery of the transparent observation window 105 is sealed with the inner wall of the observation port. A limiting hole 3 is provided in the constant temperature storage box 1, and a limiting pin 301 is slidably installed in the limiting hole 3.

[0041] In this embodiment, the constant temperature storage box 1 can be fixed on the wall and hung by fixing the hanging ears 103 in combination with pins, etc. The rubber corners 104 can provide a certain buffering capacity after the device falls, and try to avoid the internal mercury-free thermometer 5 from being damaged by impact. The mercury-free thermometer 5 can be observed through the transparent observation window 105, and the storage status of the internal mercury-free thermometer 5 can be directly observed from the outside.

[0042] Example 3

[0043] A spring pad 302 is fixed on the limit pin 301, a return spring 303 is sleeved on the limit pin 301, a displacement pull handle 304 is fixed to the end of the limit pin 301, a limit hole 401 is provided on one side of the loading box 4, the limit hole 401 cooperates with the limit pin 301, a pull-down handle 403 is fixed on the bottom of the loading box 4, a plurality of rubber blocks 405 are fixed on the front of the loading box 4 and on both sides of the storage slot 404, the rubber blocks 405 cooperate with the mercury-free thermometer 5, and the loading box A rubber pad 406 is fixedly connected to the front and the lower end of the storage slot 404. A limit slider 402 is fixedly connected to the rear of the loading box 4. A limit slide 201 is provided in the installation slot 2. The limit slide 201 cooperates with the limit slider 402. The rubber pad 406 is made entirely of rubber material and has a concave hole below it. The heat-conducting inner liner 101 is made of heat-conducting material for conducting heat from the constant-temperature heating rod 106. The heat-insulating outer shell 102 is made of heat-insulating material for reducing heat dissipation.

[0044] In this embodiment, the return spring 303 can provide a certain thrust for the spring pad 302. The spring pad 302 will drive the limit pin 301 to be inserted into the limit hole 401 under the thrust, and then fix the loading box 4 in the installation slot 2. The displacement pull handle 304 can drive the limit pin 301 to move. The rubber block 405 is made of elastic rubber. The mercury-free thermometer 5 can be buckled in the storage slot 404 using the rubber block 405. After applying a certain external force, the rubber block 405 will be deformed, and then the mercury-free thermometer 5 can be pulled out. The thermal insulation shell 102 is made of insulation material, which can minimize heat loss in the device. The limit slide 201 and the limit slider 402 cooperate with each other to limit the stroke of the loading box 4 and prevent the loading box 4 from being completely pulled out from the installation slot 2.

[0045] The working principle and usage process of the present invention are as follows: when in use, the device needs to be powered by a cable on one side. The constant temperature heating rod 106 is started to heat up to 20-30 degrees Celsius, and the heat is conducted to the inside through the heat-conducting liner 101, so that the inside of the constant temperature storage box 1 is in a warm environment, avoiding the solidification of the gallium indium tin alloy inside the mercury-free thermometer 5. The displacement pull handle 304 is used to drive the limit pin 301 to move out of the limit socket 401, and the restriction on the loading box 4 can be contacted. At this time, the loading box 4 can be driven downward by pulling down the handle 403, and then the loading box 4 can be pulled out from the inside of the constant temperature storage box 1, so that the mercury-free thermometer 5 is completely exposed. At this time, the mercury-free thermometer 5 can be manually pulled out for use.

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
