Description

[Detailed description of the invention] [Technical field of the invention] The invention has a structure in which a module, in which a sensor part, a calculation circuit part, a body temperature display part, and a power supply battery are integrally attached, is inserted into an exterior casing. Regarding an improved electronic thermometer.

[Technical background of the invention and its problems]

Conventionally, electronic thermometers have a cylindrical part integrally formed in a housing housing a body temperature calculation circuit part, a body temperature display part, and a power supply battery, and a sensor part fixed to the tip of this cylindrical part is used as a calculation circuit part. The structure is connected to the When temperature calibration is performed during the manufacturing process of an electronic thermometer configured in this way, after the arithmetic circuit section is housed in the casing, holes are made in the casing corresponding to the positions of the variable resistors for temperature calibration of the arithmetic circuit section. Calibration is performed through a small hole provided in the sensor, or calibration is performed with the arithmetic circuit section connected to the sensor section connected to the sensor section through a relatively long lead wire taken out to the outside of the casing, and then the calibration is carried out before being stored in the casing. ing. According to this method, the temperature calibration work of the electronic thermometer is performed with the sensor section, arithmetic circuit section, etc. housed or attached to the housing, so there is a risk of damaging or staining the housing during the work.
Moreover, the workability is also significantly inferior. In order to improve this, a module is formed by integrally attaching a sensor section that detects body temperature, an arithmetic circuit section that calculates body temperature based on the signal from the sensor section, a body temperature display section, and a battery for power supply to a predetermined base. However, an electronic thermometer has been proposed in which this module is fitted into an exterior casing. There is also an electronic thermometer in which the module is fitted into a casing via a sealing material such as an O-ring to form a liquid-tight structure inside the casing.

Electronic thermometers that use this module can perform temperature calibration with the module alone.
This has the advantage that the casing is not damaged and the inside of the casing can be easily made into a liquid-tight structure after the module is inserted. However, the module inserted through the opening in the housing may easily fall off from the housing unless it is handled with care until it is secured to the housing by screwing in the final assembly process. .

[Purpose of invention]

This invention was made in consideration of the above circumstances,
An object of the present invention is to provide an electronic thermometer in which a module in which a sensor section, an arithmetic circuit section, a body temperature display section, and a power supply battery are integrally attached is fixed to the casing at the same time as it is inserted into the casing. .

[Summary of the idea]

In order to achieve the above object, the present invention includes a protrusion in which one end of a transparent member that covers the body temperature display window formed in the housing protrudes inward, and a notch in the module opposite to the protrusion. The protrusion and the notch fit together when the module is inserted into the housing.

[Example of idea]

The details of the invention will be explained with reference to the illustrated embodiments.

In FIG. 1, a transparent member 3 that covers the body temperature display window 2 of the exterior housing 1 of the electronic thermometer is adhered, and one end of the transparent member 3 is slightly bent inward to form a protrusion 4. is formed. A notch 6 is provided at a position opposite to the protrusion 4 in a module 5 to which a sensor section, an arithmetic circuit section, a body temperature display section, and a power supply battery are integrally attached. In the electronic thermometer configured as described above, when the module 5 is inserted into the housing 1 through the opening 8 with the sensor section 7 first, the protrusion 4 presses the top surface of the module 5 with a slight pressing force. It slides and finally fits into the notch 6. In this state, the module 5 is properly fixed to the housing 1 and there is no risk of it falling off.
In addition, the body temperature display window 2 has a liquid-tight structure by bonding a transparent member 3, and by liquid-tightly closing the sensor part protrusion and opening 8 of the housing 1, a waterproof electronic thermometer can be easily formed. can do.

As shown in FIG. 2, after the module 5 is inserted into the housing 1, a transparent member 3' having a protrusion 4' is covered and adhered to the body temperature display window 2 from the outside of the housing 1, and the protrusion 4 is attached to the body temperature display window 2. ′ is fitted into the notch 6 of the module 5,
The same effects as in the embodiment described above can be obtained.

[Effect of idea]

As described above, the present invention is an electronic thermometer in which a module, in which a sensor part, arithmetic circuit part, a body temperature display part, and a power supply battery are integrally attached, is fitted into an exterior casing, and the module is fitted into an exterior casing. The module has a protrusion in which one end of the transparent member that covers the body temperature display window protrudes inward, and a notch provided in the module, and when the module is inserted into the housing, the protrusion and the notch are The structure is such that the module is fixed to the housing by mating with the parts, so the module does not fall off the housing during the assembly process of the electronic thermometer, making the work easier and more efficient. be. Further, since the transparent member covering the body temperature display window is bonded in a liquid-tight manner, this electronic thermometer has excellent effects such as being able to easily have a waterproof structure.
