The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Referring to fig. 1 to 3, an embodiment of the present utility model provides an electronic thermometer, which includes a housing 1, a main board 3, a temperature sensing head 4, and a thermistor 5. The display screen 2 is arranged outside the shell 1, the display screen 2 is used for displaying the measured temperature, the main board 3 is arranged in the shell 1, the display screen 2 is electrically connected with the main board 3, a battery is arranged on the main board 3 and used for supplying power to the thermometer, the battery can be particularly but not exclusively a button battery, the temperature sensing head 4 is arranged at the end part of the shell 1, the inside of the temperature sensing head 4 is of a hollow structure and used for accommodating the head part of the thermistor 5, the temperature sensing head 4 is used for contacting an object to be measured to conduct heat transfer, the head part 51 of the thermistor 5 is accommodated in the temperature sensing head 4, the electrode 52 of the thermistor 5 is electrically connected with the main board 3, the bottom of the temperature sensing head 4 is filled with metal 6, the metal 6 is filled in a liquid state in production, and the metal 6 is wrapped around the head part of the thermistor 5.
During installation, the head 51 of the thermistor 5 is placed in the temperature sensing head 4, then the liquid metal 6 is filled in, or the liquid metal 6 is filled in the temperature sensing head 4, then the head 51 of the thermistor is placed in the temperature sensing head 4, then the electrode 52 of the thermistor 5 is connected with the main board 3, then the shell 1 is installed, and finally the temperature sensing head 4 is connected and fixed with the shell 1.
By filling the metal 6 in the temperature sensing head 4, the metal 6 is filled between the inner wall of the temperature sensing head 4 and the head 51 of the thermistor 5, on one hand, the metal 6 is adopted as a heat conduction medium of the temperature sensing head 4 and the thermistor 5 to realize the omnibearing heat conduction between the head 51 of the thermistor 5 and the temperature sensing head 4, so that the thermistor 5 can reach the temperature consistent with the external contact end in a very short time, on the other hand, the flowing characteristic of the metal 6 can be better contacted and attached with the head 51 of the thermistor 5 during filling, the temperature conduction area is maximized, and the temperature measurement is quick and accurate based on the two aspects.
According to the electronic thermometer provided by the embodiment of the utility model, the metal 6 is used as a heat conduction medium between the temperature sensing head 4 and the thermistor 5, so that heat transfer is extremely rapid, and the measurement result of the electronic thermometer is rapid and accurate.
Specifically, the temperature sensing head 4 is made of a metal material.
Further, referring to fig. 2, the filling height of the metal 6 is greater than the height of the head 51 of the thermistor 5. Thus, the metal can be ensured to completely wrap the head 51 of the thermistor 5, and the contact area between the thermistor head and the metal is increased, so that the heat conduction efficiency is improved.
Further, the metal 6 includes one of a liquid metal, a low-temperature metal, or a low-melting point metal. The liquid metal is the metal with liquid property in a normal state, does not need to be melted in production, and maintains a liquid state after filling, so that the production and the filling are convenient; the low-temperature metal and the low-melting-point metal have the common points of low melting points, and the influence of the temperature of the low-temperature metal and the low-melting-point metal on insulating paint of the thermistor can be avoided when the low-temperature metal and the low-melting-point metal are melted and filled in production and processing, so that the thermistor is damaged in a perception way.
In particular, the liquid metal may be, but is not limited to, gallium-based metalloid alloys or indium-based metalloid alloys.
In particular, the low temperature metal may include, but is not limited to, gallium-based metalloid alloys or indium-based metalloid alloys, and the low melting point metal may include, but is not limited to, metallic tin.
Further, the temperature sensing head 4 is filled with a curing glue 7 above the metal 6. The use of the curable adhesive 7 can seal the filled metal 6 when filling with a liquid metal or a metal of a lower melting point among the low melting point metals used (i.e., a technique that is easily liquefied at a higher temperature). In this embodiment, the curing glue 7 may be filled according to the metal 6 used, for example, when the metal used in higher air temperature is still stable and remains in a solid state, the filling of the curing glue 7 may be omitted.
Referring to fig. 3, further, a clamping portion 11 adapted to the temperature sensing head 4 is provided at one end of the housing 1 connected to the temperature sensing head 4, and the clamping portion 11 is clamped into the temperature sensing head 4 and is connected to the temperature sensing head 4 in a clamping manner. The mode of clamping connection is adopted, so that the temperature sensing head 4 and the shell 1 can be assembled more conveniently and rapidly. Specifically, in order to further strengthen the fixation, glue may be injected between the clamping portion 11 and the temperature sensing head 4 to make the connection between them more stable.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
