Background

All objects with a temperature above absolute zero continuously emit infrared radiant energy into the surrounding space. The magnitude of the infrared radiation energy of an object and its distribution by wavelength are very closely related to its surface temperature. Therefore, by measuring the infrared energy radiated by the object itself, the surface temperature can be accurately measured, which is the objective basis on which infrared radiation temperature measurement is based.

Detailed Description

In order to make the aforementioned and other objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below.

Please refer to fig. 1 to fig. 2. The embodiment provides a temperature regulating probe which is used in a thermometer and comprises a sensor 6 and a temperature regulating element. The sensor has an outer wall 61, the end of the outer wall 61 being provided with a radiation opening 21; and the temperature regulating element is provided on a portion of the sensor near the end and outside the sensor 6. The outer wall 61 and the sensor in this application are both part of one and the same, so that the assembly is easier, and, if a housing is provided between the sensor and the temperature-regulating element, a gap inevitably exists between the sensor and the housing, which affects the heat transfer efficiency.

Simultaneously, the probe that adjusts the temperature in this application does not include the great constant temperature piece of volume, directly sets up the temperature regulating element on the shell, thereby heat conduction efficiency provides effectual heating efficiency that has increased greatly, can be very fast with whole probe rapid heating, reduces the time that the user waited for the heating.

The outer wall 61 is made of materials with good heat conductivity and large heat capacity, such as brass, and further, in order to improve the heating efficiency, heat-conducting glue can be coated between the outer wall 61 and the temperature adjusting element.

In the embodiment, the temperature adjusting element is added in the temperature probe, and the probe can be heated or cooled to the temperature close to the measured part according to the use environment, so that the temperature difference between the probe and the measured part is reduced, the heat exchange between the probe and the measured part is reduced, and the temperature fluctuation of the measured part is reduced.

The temperature probe can be electrically connected with the instruction unit, and a user can input the specified temperature to the instruction structure so as to control the temperature adjusting element to heat or cool, so that the probe reaches the required specified temperature. The temperature probe can also be electrically connected with the detection unit, and the temperature value detected by the detection unit for the first time is used for controlling the temperature regulating element to heat or cool, so that the probe reaches the detected temperature value. If some thermometers are used fixedly, such as thermometers, because the temperature of a human body is higher than that of the thermometers, only the heating element can be arranged and a fixed value can be set, and after the thermometers are turned on, the fixed value set by the heating value of the temperature adjusting element can be automatically controlled.

More specifically, the heating element in this embodiment is a heating wire 11, and two ends of the heating wire extend downwards to form two legs, wherein one leg 13 is formed on the heating wire at the end of the probe, the other 14 is formed on the heating wire at the tail of the probe, and the leg 13 is longer than the leg 14. In order to make the contact area between the heating wire and the outer wall larger, the outer wall is provided with an indentation matched with the heating wire, and the arrangement of the indentation is also beneficial to the processing, winding and assembling of the heating wire. In other embodiments, the heating element may be any one or more of a resistor, a heating block, and a heating ring 12. The material of the heating element can be a ceramic heater, a power resistor, a metal heating wire or the like.

The temperature-regulating element in this embodiment has one end extending from said end of said outer wall. In the actual manufacturing process, the temperature adjusting element and the end part of the sensor are a short distance, because the distance between the end part of the outer wall and a user is the minimum of the whole temperature adjusting probe when the temperature adjusting probe is used, the most important is to ensure that the end part of the temperature adjusting probe is fully adjusted during temperature adjustment, therefore, the temperature adjusting element extends from the end part of the outer wall, the temperature difference between the probe and the measured part can be effectively reduced, the heat exchange between the probe and the measured part is reduced, and the temperature floating of the measured part is reduced. However, the temperature control element in the present application is not arranged beyond the end of the outer wall, i.e. the temperature control element in the present application has one end at most flush with the end.

In this embodiment, the sensor is an infrared sensor, the outer wall has a boss, and the other end of the infrared sensor extends to the boss at most. The infrared rays incident through the radiation port 21 are transmitted to the infrared sensor 6, and then the signals are further transmitted to a control system or a detection system for analysis and calculation.

In this embodiment, the temperature adjusting element is one, and extends along the longitudinal direction of the temperature adjusting probe, and the axial length of the temperature adjusting element is greater than that of the temperature adjusting element, so as to ensure the volume of the temperature adjusting element and increase the heating efficiency. In other embodiments, there may be a plurality of temperature control elements, which are distributed uniformly in the longitudinal direction.

In other embodiments, the temperature adjusting element may include a heating element and a cooling element, and the heating element and the cooling element are spaced apart from each other. When the measuring range of the thermometer is larger, the applicability range is also larger, sometimes the temperature of the thermometer is higher than the measured part, sometimes the temperature of the thermometer is lower than the measured part, therefore, when the temperature adjusting element comprises the heating element and the cooling element, the temperature of the probe can be adjusted at any time according to the requirement. Furthermore, the tempering element can comprise only a cooling element.

Please refer to fig. 3 to fig. 6. The utility model also provides a thermometer, including thermometer main part 5 and any as above the probe adjusts the temperature, the probe that adjusts the temperature and thermometer main part 5 are connected. The thermometer main body 5 is internally provided with an instruction structure or a detection structure, the temperature probe can be electrically connected with the instruction unit, and a user can input the specified temperature for the instruction structure, so that the temperature adjusting element is controlled to heat or cool, and the probe can reach the required specified temperature. The temperature probe can also be electrically connected with the detection unit, and the temperature value detected by the detection unit for the first time is used for controlling the temperature regulating element to heat or cool, so that the probe reaches the detected temperature value. If some thermometers are used fixedly, such as thermometers, because the temperature of a human body is higher than that of the thermometers, only the heating element can be arranged and a fixed value can be set, and after the thermometers are turned on, the fixed value set by the heating value of the temperature adjusting element can be automatically controlled.

The thermometer also comprises an upper cover 4, and fig. 5 and 6 respectively show schematic views of the upper cover 4 at different angles. The upper cover 4 is provided with an upper cover hole 41, and the radiation port 21 of the temperature adjusting probe corresponds to the position of the upper cover hole 41.
