Description

Thermometer with improved buzzer structure

Technical Field

The present invention relates to a thermometer for medical aids, and more particularly to a thermometer with an improved buzzer structure.

Background

Generally, clinical practice, hospital or home use is mostly equipped with a thermometer for measuring the body temperature of a patient, and the method for measuring the body temperature mainly comprises clamping the thermometer to the armpit, the thigh or the tongue of the patient, and balancing the temperature with the thermal contact surface of the thermometer, and further using the mercury or electronic equipment in the thermometer to judge the body temperature.

When the electronic thermometer is used for measuring different positions of a human body, the time for reaching temperature balance is different, so that the electronic thermometer on the market is added with a timing and buzzing function.

As shown in fig. 1, the general structure of the buzzer 10 includes a resonance space (not shown) surrounded by a surrounding wall, and a buzzer 11 is disposed in the resonance space (not shown), when the buzzer 11 vibrates, the sound generated by the buzzer 10 is increased by the sound box effect of the resonance space (not shown).

However, since the thermometer is small in volume, the buzzer 10 mounted in the thermometer is also of a small type, and the smaller the volume of the buzzer 10, the smaller the resonance space (not shown) is, the limited effect of generating resonance and increasing sound is, and thus, the electronic thermometer tends to have a defect of insufficient buzzer sound.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve the not enough defect of the buzzer of electrothermometer, and then improve the sound of buzzer.

To achieve the above object, the present invention provides a clinical thermometer with an improved buzzer structure, comprising:

the shell is provided with an outer wall which surrounds and defines an accommodating space;

the central processing unit is arranged in the accommodating space;

the buzzer is arranged in the accommodating space and electrically connected with the central processing unit, and the buzzer is connected with the shell.

In a preferred embodiment, one end of the housing has a thermal contact.

In a preferred embodiment, the other end of the housing, where the thermal contact portion is installed, has an opening communicating with the accommodating space, and a cover is provided to close the opening.

In a preferred embodiment, the buzzer has a resonant wall, the resonant wall surrounds to define a resonant space, a buzzer is disposed in the resonant space, and the buzzer is electrically connected to the cpu.

In a preferred embodiment, the buzzer is protruded with a contact portion, and the contact portion is in contact with the shell.

In a preferred embodiment, the buzzer has a resonant wall surrounding to define a resonant space, and the contact portion protrudes from the resonant wall toward a side of the resonant space.

In a preferred embodiment, the buzzer has a resonant wall, the resonant wall surrounds to define a resonant space, and the resonant wall of the buzzer is directly contacted with the shell.

When the vibrations of buzzing piece are transmitted to the resonance wall, make the resonance space produces the sympathetic response, and then produce sound, simultaneously, the vibration that buzzing piece produced passes through the contact site transmits to the casing makes also produce the sympathetic response in the accommodation space, because the accommodation space is far more than the resonance space, and then let the buzzing sound that its produced bigger.

More preferably, because the utility model discloses by buzzer with the casing contact makes the sound that whole can produce bigger, omits to install the amplifier additional on central processing unit and goes to amplify its sound, because does not install the amplifier additional, and need not supply with extra electric power and give the amplifier, makes the utility model discloses the sound of bee sound is amplified, but electric power maintains former demand can.

Detailed Description

The technical solution of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 2 to 4, the utility model relates to a clinical thermometer with improved buzzer structure, which comprises:

a housing 20 having an outer wall 21 surrounding and defining a receiving space 22; in the present embodiment, one end of the housing 20 has a thermal contact portion 23, the thermal contact portion 23 is mainly made of metal or material easy to conduct heat, and is used to be clamped at the position of the patient for measuring the body temperature, and the other end of the housing 20, which is provided with the thermal contact portion 23, has an opening 24 communicating with the accommodating space 22.

A central processing unit 30 installed in the accommodating space 22; in the present embodiment, the cpu 30 is configured to receive the signal from the temperature sensor 31 and display the temperature, and the temperature sensor 31 is a temperature sensitive resistor, which belongs to the prior art and is not described herein again.

A buzzer 40 installed in the accommodating space 22 and electrically connected to the cpu 30, wherein the buzzer 40 is connected to the housing 20; in this embodiment, the buzzer 40 has a resonance wall 41, the resonance wall 41 surrounds and defines a resonance space 42, a buzzer 43 is disposed in the resonance space 42, the buzzer 43 is electrically connected to the cpu 30, and when the cpu 30 transmits power to the buzzer 43, the buzzer 43 vibrates in the resonance space 42 to generate a buzzer sound.

Particularly, the buzzer 40 is provided with a contact portion 44 in a protruding manner, the contact portion 44 protrudes from one side surface of the resonant wall 41 opposite to the resonant space 42 and contacts with the housing 20, the contact portion 44 contacts with the housing 20, when the buzzer 43 vibrates, the vibration is transmitted to the outer wall 21 through the contact portion 44, so that the outer wall 21 resonates around the formed accommodating space 22, and further the sound is louder.

Preferably, a cover 50 is further provided to close the opening 24 to prevent the cpu 30 and the buzzer 40 from being separated from the accommodating space 22.

In view of the above, the present invention provides a structure configuration and connection relationship thereof in a preferred embodiment, the structure of the present invention can achieve the following effects:

as shown in fig. 4, when the timer in the cpu 30 reaches a predetermined time, the cpu 30 transmits power to the buzzer 43 to vibrate the buzzer 43, and the vibration of the buzzer 43 is transmitted to the resonance wall 41 to resonate the resonance space 42, thereby generating sound, and meanwhile, the vibration generated by the buzzer 43 is transmitted to the housing 20 through the contact portion 44 to resonate the accommodating space 22, and the accommodating space 22 is much larger than the resonance space 42, thereby generating a larger buzzer.

More preferably, because the utility model discloses by the contact site 44 and the casing 20 contact of bee calling organ 40, make the sound that wholly can produce bigger, omit to install the amplifier additional on central processing unit and go to amplify its sound, because do not install the amplifier additional, and need not supply with extra electric power and give the amplifier, make the utility model discloses the buzzing sound has been amplified, but electric power maintains former demand can.

As shown in fig. 5, in another embodiment of the present invention, the resonance wall 41 of the buzzer 40 directly contacts with the housing 20, so that when the buzzer 43 generates vibration, the vibration can be directly transmitted to the housing 20 through the resonance wall 41, and the generated buzzer is larger.
