Description

Technical Field

[0001] The utility model relates to the field of thermometers, in particular to a digital display thermometer. Background Art

[0002] Bimetallic thermometers are commonly used in industrial environments. They can directly measure the temperature of liquid, vapor, and gaseous media within a range of -80°C to +500°C in various production processes. These industrial bimetallic thermometers primarily consist of a multilayered metal sheet composed of two or more metal sheets laminated together. They operate by utilizing the principle that two different metals expand at different temperatures. These bimetallic thermometers are wound into a circular, curved shape. When one end expands due to heat, it rotates the pointer, and the instrument displays the temperature corresponding to the thermoelectric potential.

[0003] Currently, bimetallic thermometers use a bimetallic element to sense temperature and drive a pointer to indicate temperature. This pointer is prone to falling off and becoming damaged, and in vibrating environments, the pointer is prone to shaking, making accurate readings difficult. Furthermore, in some special circumstances, the measurement operator cannot be present for on-site observation (for example, when the ambient temperature is too high for long-term observation or when the measurement location is not suitable for long-term observation). This can make temperature measurement difficult. Therefore, a thermometer with more accurate readings and greater safety is needed. Utility Model Content

[0004] The purpose of the present invention is to provide a digital thermometer to solve the problems raised in the above background technology.

[0005] The utility model solves the technical problem by adopting the following technical solutions:

[0006] A digital thermometer comprises a measuring tube, a connecting nut fixedly provided at the top end of the measuring tube, the lower side of the connecting nut being located on the wall of the measuring tube and fixing the thread, a thermal resistor being provided at the bottom of the inner cavity of the measuring tube, the output end of the thermal resistor being connected to one end of a wire, the wire passing through the top end of the measuring tube and extending to the outside, the other end of the wire being connected to a meter head, a digital display being provided on the meter head, the top end of the measuring tube and the meter head being crimped and connected by a bellows, and the wire being arranged inside the bellows.

[0007] Preferably, thermal conductive silicone grease is filled between the thermal resistor and the inner wall of the measuring tube.

[0008] Preferably, a platform piece is provided on the meter head, and the platform piece can fix the meter head at any place by means of bolts.

[0009] The advantages and positive effects of the utility model are:

[0010] 1. The utility model adopts the form of separating the meter head and the temperature measuring part, so the observer does not need to stand at the measurement point to view and record the data, avoiding the impact of high temperature environment on the human body and the measurement point being at a high place or in a place where long-term observation conditions are not available. At the same time, it prevents the instrument from being in a high temperature environment for a long time, thereby increasing its service life.

[0011] 2. The utility model uses an electronic digital display screen, which can accurately display the temperature to 1 decimal place, and obtain the temperature value more accurately and quickly. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0017] The following combination Figure 1-2 The utility model is described in detail. For the convenience of description, the directions mentioned below are defined as follows: the up, down, left, right, front and back directions mentioned below are the same as Figure 1 The front, back, left, right, up and down directions of the view are consistent. Figure 1 This is a front view of the device of the utility model. Figure 1 The directions shown are consistent with the front, back, left, right, up and down directions of the device of the present invention when viewed from the front.

[0018] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings:

[0019] See also Figure 1-2The utility model provides an embodiment: a digital thermometer, including a measuring tube 10, a connecting nut 12 is fixed on the top of the measuring tube 10, the lower side of the connecting nut 12 is located on the wall of the measuring tube 10 and fixed with the thread 11, a thermal resistor 16 is provided at the bottom of the inner cavity of the measuring tube 10, the output end of the thermal resistor 16 is connected to one end of a wire 18, the wire 18 passes through the top of the measuring tube 10 and extends to the outside, the other end of the wire 18 is connected to a header 14, a digital display screen 17 is provided on the header 14, the top of the measuring tube 10 and the header 14 are crimped and connected by a bellows 13, and the wire 18 is arranged inside the bellows 13.

[0020] In addition, in one embodiment, thermal grease is filled between the thermal resistor 16 and the inner wall of the measuring tube 10 .

[0021] In addition, in one embodiment, a platform piece 15 is provided on the meter head 14 , and the platform piece 15 can fix the meter head 14 at any place by means of bolts.

[0022] During specific implementation; by rotating the connecting nut 12, the thread 11 is connected to the equipment connection port, and then the measuring tube 10 is placed in the area to be measured. The heat generated by the equipment to be tested enters the interior of the measuring tube 10 through the wall of the measuring tube 10 through heat conduction, and is better in contact with the thermal resistor 16 under the action of the thermal conductive silica gel, so as to better measure the temperature, and then transmit the data to the header 14. The header 14 displays the temperature and other information through the digital display screen 17, so that the observer can read the value more conveniently and accurately. The present invention can accurately read 1 decimal place. At the same time, the pointer type is currently used. The user must be near the equipment to be tested and read the value at close range on the spot, which may cause high temperature burns or fall from a height, which is very dangerous. The present invention adopts an electronic reading type, which can accurately read data from a distance and on the ground. At the same time, it also prevents the instrument from being in a high temperature environment for a long time, thereby increasing its service life.

[0023] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation methods. Any other implementation methods derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
