Description

Technical Field

[0001] This utility model relates to the field of temperature measurement technology, specifically to a portable temperature measurement device. Background Technology

[0002] A mercury thermometer is an instrument that measures temperature using the principle of thermal expansion and contraction of mercury. It features high accuracy and stability. Its outer shell is typically made of glass, and it contains mercury. Through a thin tube design between the glass bulb and a straight tube, the mercury expands or contracts under the influence of body temperature, thus displaying temperature changes.

[0003] However, most mercury thermometers on the market are made of glass in the shape of a rod. They are prone to breaking when they are bumped during transport, which can cause mercury leakage and contamination of the surrounding area. In addition, the broken pieces can easily cut fingers and pose a certain danger. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a portable temperature measuring device, in which the mercury thermometer is bent and deformed and filled into a disc-shaped outer shell for use, thereby making it easy to carry, and if damaged, it will remain inside the outer shell.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A portable temperature measuring device includes a mercury thermometer with a thin tube inside, containing mercury. The measuring end is located at one end of the mercury thermometer and connected to the thin tube. The device also includes:

[0007] The temperature measuring disk has a mercury thermometer bent and deformed into a spiral shape and fixed on the top surface of the temperature measuring disk, with the measuring end arranged on the outside and connected to the top surface of the temperature measuring disk.

[0008] The outer casing is fitted and fixed above the temperature measuring disc, and the mercury thermometer is arranged inside the outer casing.

[0009] When the centrifugal structure is rotated, the temperature measuring disk and the outer shell rotate, and the mercury inside the mercury thermometer flows along the thin tube to the measuring end under the action of centrifugal force.

[0010] As an improvement, the rotating centrifugal structure includes a grip, a rotating shaft, and a bearing; the temperature measuring disc is an annular structure, the rotating shaft is arranged vertically and is rotatably set inside the temperature measuring disc through the bearing, and the top is set through the outer shell, the grip is set horizontally and is connected and fixed together with the upper and lower ends of the rotating shaft respectively, and the lower grip is movably sleeved inside the temperature measuring disc, and the bottom surface is arranged above the bottom surface of the temperature measuring disc.

[0011] As an improvement, the outer shell is made of heat-insulating material, and a reading window is embedded in the top wall, with the mercury thermometer scale facing upwards, and the reading window is set to correspond to the mercury thermometer.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] 1. The mercury thermometer of this utility model is bent and deformed and filled into a disc-shaped shell for use. In the event of a collision and the mercury thermometer breaks, the fragments and mercury will remain inside the shell, which will not cause pollution to the surrounding environment and is safer to use.

[0014] 2. The present invention is disc-shaped, which requires less length for storage and is more convenient to carry compared to a strip shape.

[0015] 3. This utility model is equipped with a rotating centrifugal structure, which allows the mercury inside the mercury thermometer to flow along the thin tube to the measuring end under centrifugal force through rotation, making it more convenient to use and adding a certain degree of fun.

[0016] 4. The measuring end of this invention has a larger area and is easier to fit on the skin, resulting in faster temperature measurement and simpler and more convenient use. Attached Figure Description

Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] A portable temperature measuring device, such as Figure 1 , Figure 2 As shown, it specifically includes:

[0025] The temperature measuring disk 2 and the outer shell 1 are: a temperature measuring disk 2, a ring-shaped structure made of metal with excellent thermal conductivity; and an outer shell 1, a circular cover structure made of heat-insulating material with an open bottom and a pre-drilled circular hole at the center of the top, positioned above the temperature measuring disk 2 and fixed to the temperature measuring disk 2 at the bottom. A transparent reading window 3 is embedded in the top wall of the outer shell 1, and the reading window 3 is as follows: Figure 1 As shown, it is arranged in a spiral shape.

[0026] Mercury thermometer 7, such as Figure 3 As shown, it is arranged inside the outer shell 1, and the corresponding reading window 3 is bent and deformed into a spiral shape and fixed on the top surface of the temperature measuring disk 2. A thin tube 8 is set inside it, and mercury is placed inside the thin tube 8. The measuring end 9 is arranged at one end on the outside and connected to the thin tube 8. It is bent downward and connected to the top surface of the temperature measuring disk 2. A scale is set on the top surface of the mercury thermometer 7 for temperature reading.

[0027] Rotate the centrifugal structure, as... Figure 4As shown, the structure includes a grip plate 4, a rotating shaft 5, and a bearing 6. The temperature measuring disk 2 is an annular structure. The rotating shaft 5 is vertically arranged and rotatably mounted inside the temperature measuring disk 2 via the bearing 6. Its top passes through a circular hole in the outer shell 1 (rotationally sealing the rotating shaft 5 and the outer shell 1). The grip plate 4 is horizontally arranged and connected and fixed to the upper and lower ends of the rotating shaft 5. The lower grip plate 4 is movably fitted inside the temperature measuring disk 2, with its bottom surface positioned above the bottom surface of the temperature measuring disk 2. Simultaneously, the bottom surface of the upper grip plate 4 is in contact with the top surface of the outer shell 1. After the temperature measuring disk 2 and the outer shell 1 are rotated by a centrifugal structure, the mercury in the mercury thermometer 7 flows along the thin tube 8 to the measuring end 9 under the action of centrifugal force.

[0028] In the specific implementation of this embodiment:

[0029] Before measurement, hold the upper and lower handles 4 with your fingers and rotate the outer casing 1 to make the temperature measuring disc 2 and the outer casing 1 rotate, which in turn rotates the internal mercury thermometer 7. Under the action of centrifugal force, the mercury in the mercury thermometer 7 flows along the thin tube 8 to the outer measuring end 9. Place this device inside your clothing with the temperature measuring disc 2 against your skin, so that heat is transferred to the mercury in the thin tube 8 through the temperature measuring disc 2 and the measuring end 9. The mercury expands and contracts with temperature changes. After a period of time, the mercury temperature stabilizes at body temperature and stops expanding. Take out the device and read your body temperature through the reading window 3 and scale on the top. After use, rotate the device again to make the mercury flow along the thin tube 8 to the outer measuring end 9 for the next use.

[0030] When carrying it, place it in the matching bag, or store it directly in your pocket or utility bag.

[0031] The present invention and its embodiments have been described above.
