Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the various embodiments of the present invention belong. The terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning that is consistent with their contextual meaning in the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein in various embodiments of the present invention.

Referring to fig. 1 and 2, the present embodiment provides a portable multifunctional thermometer 10, where the thermometer 10 not only can perform infrared temperature measurement, but also can provide a vein display function, and has the advantages of diverse functions, small volume, portability, and the like. The portable multi-function thermometer 10 will be described in detail below.

Exemplarily, the portable multifunctional thermometer 10 includes an infrared temperature measuring unit 110, a control unit 120, a control switch 130 and a vein visualizing unit 140, and the infrared temperature measuring unit 110, the control switch 130 and the vein visualizing unit 140 are all connected to the control unit 120. The infrared temperature measuring unit 110 is mainly used for measuring the temperature of a target object; the control unit 120 is mainly used to control the red light emitting function of the vein visualization unit 140 to be turned on or off according to the on or off state of the control switch 130. For example, when the control switch 130 is in an open state, the vein-revealing unit 140 will emit infrared light; and when the control switch 130 is in the off state, the vein-revealing unit 140 will not emit infrared light. Wherein, the red light can be used for irradiating the palm center of the target object when the target object holds the thermometer 10, thereby realizing vein vessel visualization.

In this embodiment, the infrared temperature measuring unit 110 mainly includes an infrared temperature sensor 111, as shown in fig. 2, the infrared temperature sensor 111 can be placed on the front side of the casing of the temperature measuring instrument 10, and correspondingly, a through hole corresponding to the infrared temperature sensor 111 is provided on the front side of the casing. When measuring the temperature, the thermometer 10 can be held by hand to enable the front side to face the temperature measuring part of the target object, such as the forehead, the ear cavity and the like, and the infrared temperature sensor 111 detects the infrared energy radiated by the human body, so as to calculate the surface temperature of the human body. It should be understood that the infrared temperature measuring unit 110 further includes a signal processing circuit connected to the infrared sensor, such as a signal amplifying circuit and an analog-to-digital converting circuit, which are described in detail in the related art and will not be described in detail herein.

The vein visualizing unit 140 mainly includes a circuit for emitting red light, that is, visualizing the position of the vein blood vessel of the palm of the observation target using the emitted red light. This is because, when the red light source irradiates on the skin, the contrast between the vein vessel and the surrounding tissue is increased because the hemoglobin in the vein vessel absorbs red light more strongly than the surrounding tissue, and thus, under the irradiation of the red light source, the vein vessel and the surrounding tissue will show different colors, thereby achieving the vein positioning function.

Illustratively, the housing has a vein-appearing area A, which may be generally transparent as shown in FIG. 2, so that red light emitted from the interior of the housing of the thermometer 10 can shine through the vein-appearing area A onto the palm center of the hand. Exemplarily, the vein visualization unit 140 may emit external light using a laser light source emitting red light, a red LED light source, or the like. For example, the red light can be near infrared light with a wavelength of 620-760 nm. It is understood that the housing further includes a driving circuit for driving the laser light source or the LED light source, for example, a driving circuit formed by a transistor, a MOS transistor, or the like may be used.

Considering that the emitted red light will radiate a large amount of heat when reaching a certain intensity, and the housing is usually made of plastic, optionally, the thermometer 10 may be provided with a heat dissipation structure inside the housing, such as a metal heat sink, so as to accelerate heat dissipation, and further improve the service life of the thermometer 10. Further optionally, the vein visualization unit 140 further includes an adjusting circuit for adjusting the intensity of the red light and a corresponding intensity level setting switch, so that when the palm of the target object is thick, the current intensity of the red light can be adjusted through the intensity level setting switch, thereby achieving the effect of enhancing vein visualization.

It can be understood that, because the diameter of the portable thermometer 10 is smaller, the user only needs to hold the thermometer 10 when using the thermometer 10, and the emitted red light is directly irradiated on the palm of the hand, because the palm can form a relatively sealed wrapping state when holding the thermometer 10, the emitted red light can be maximally irradiated on the palm of the hand, compared with the existing vein imaging instrument adopting the spaced irradiation, the thermometer 10 of the embodiment can reduce the intensity requirement on the emission of the red light, further reduce the requirement on hardware design, facilitate the miniaturization of the volume to realize portable design, and the like. In addition, by sharing the housing, the control unit 120, and other hardware devices with the thermometer 10, two functions of infrared temperature measurement and vein imaging can be realized at a low cost, and the utility model has high practicability.

In a preferred embodiment, the thermometer 10 further comprises a raised structure 121 disposed on the housing, as shown in fig. 3, the raised structure 121 can better fit against the palm center of the target subject when the target subject holds the thermometer 10. Exemplarily, the protruding structure 121 is transparent, so that the red light emitted from the vein revealing unit 140 located in the housing can be irradiated on the palm center of the hand through the protruding structure 121. Furthermore, the protruding structure 121 can also adopt an arc-shaped structure with a light-gathering effect, and in addition, the arc-shaped structure is more in accordance with the human body design, and the hand feeling during holding is better, so that the user experience can be improved.

For example, as shown in FIG. 3, when the thermometer 10 is elongated, the infrared temperature sensor 111 will be disposed at the front end of the housing, which may also be referred to as a front probe, and the raised structure 121 may be disposed at the rear main body portion of the housing. As to which region of the rear body the protrusion structure 121 is located, the design may be based on the length and the overall structural layout of the thermometer 10, for example, considering that the thermometer 10 usually adopts a rechargeable battery structure, the protrusion structure 121 and the battery structure may be reasonably distributed at different positions of the body.

The control switch 130 is used primarily to control the opening or closing of the vein-revealing function. In an alternative embodiment, as shown in fig. 2, the control switch 130 is a mechanical switch disposed on the housing of the thermometer 10, such as a push-button type mechanical switch or a push-type mechanical switch. The specific location may be determined according to the actual design, for example, the specific location may be located beside the housing relative to the front side of the housing.

In another alternative embodiment, the control switch 130 is a touch switch, which may also be referred to as a touch sensitive switch. When the target object touches the switch, the control unit 120 will detect that the switch is in an on state and turn on the red light emitting function. Exemplarily, the touch switch may employ a touch electrode switch composed of two electrodes, wherein a first electrode and a second electrode are respectively located at different positions of the housing, fig. 3 shows only the first electrode, and the second electrode is not shown. When the palm of the target object holds the thermometer 10 and touches the first electrode and the second electrode at the same time, the first electrode and the second electrode will be in a connection and conduction state because the human body is a conductor, and the control unit 120 will detect that the control switch 130 is in an open state. It can be understood that, normally, when the thermometer 10 performs infrared temperature measurement, it is not necessary to completely hold the thermometer 10 with a palm, so the first electrode and the second electrode are not connected and conducted, that is, the touch switch is normally in an off state when performing infrared temperature measurement.

As another embodiment, the control unit 120 may further be configured to control the infrared thermometry unit 110 to turn off and turn on the vein visualization unit 140 when detecting that the control switch 130 is turned on, i.e., the infrared thermometry function is stopped when the vein visualization function is used. It will be appreciated that these two functions can be switched by the control switch 130.

In a preferred embodiment, as shown in fig. 4, the portable thermometer 10 may further include: the distance measuring unit 150 is located on the same side as the infrared temperature measuring unit 110, the distance measuring unit 150 is connected to the control unit 120, and the distance measuring unit 150 is mainly used for measuring the distance between the target object and the temperature measuring instrument 10. Considering that the overall volume and the front space are often small, the distance measuring unit 150 may exemplarily use a laser distance measuring module with a small volume, so that a smaller opening may be designed at the front side of the housing, as shown in fig. 5.

The distance measuring unit 150 can well judge whether the temperature measuring distance between the measured object and the temperature measuring instrument 10 is reasonable, especially when the distance is too far, a user may worry that the measuring result may be inaccurate, and the like.

Further, the control unit 120 is further configured to determine whether the current target object is located within a preset temperature measurement range according to the distance measured by the distance measurement unit 150, and only when the target object is located within the preset temperature measurement range, the control unit controls to start the infrared temperature measurement unit 110 to perform temperature measurement. Optionally, in the process of gradually approaching the target object, continuous temperature measurement is further performed to obtain a plurality of temperature values, and at this time, the highest temperature value may be used as the displayed temperature value.

It can be understood that the preset temperature measuring range can be set or adjusted according to actual requirements, and is not limited herein. In this way, when the target object does not enter the temperature measurement range, the infrared temperature measurement unit 110 may be in a sleep state or a low power consumption state, and only when it is detected that the target object is located in the preset temperature measurement range, the infrared temperature measurement unit 110 is controlled to be started to measure the temperature of the target object, so that the power consumption of the system may be reduced.

In one embodiment, as shown in fig. 4, the portable thermometer 10 may further include a light indicating unit 160 disposed on the housing, and the light indicating unit 160 is connected to the control unit 120, and is mainly used for indicating the current status of the thermometer 10, which may include, but is not limited to, a function use indication, a power indication, and the like. For example, the infrared temperature measurement function and the vein display can be indicated by different lights of the same indicator light, or can be indicated by different indicator lights respectively. The indicator light for indicating the electric quantity may be one or more, and may be specifically designed according to actual requirements, and is not limited herein.

Exemplarily, the control unit 120 may be implemented by an MCU having signal triggering and logic operation functions, such as a single chip microcomputer of STM32 series and AVR series, which may be specifically selected according to actual requirements, and is not limited herein. It is understood that the thermometer 10 further includes a power supply unit for providing working power, and exemplarily, the power supply unit may include a rechargeable battery, a power management chip, a charging interface, and the like, wherein the charging interface is used for an external power supply to charge the rechargeable battery, and the power management chip is mainly used for monitoring the power state of the rechargeable battery and transmitting the power state to the control unit 120.

As an alternative embodiment, as shown in FIG. 2, the thermometer 10 may be elongated, in which case the average diameter of the housing will be less than the length of the housing. For example, the diameters of the different regions may be the same or different for an elongated housing, and the diameters of the regions may be adjusted appropriately for a hand-held region, so as to facilitate a user to hold the thermometer 10 completely. Of course, the thermometer 10 may also have other shapes, which are not limited herein, but should satisfy the vein appearing effect when the palm center of the user is placed in the vein appearing area a of the thermometer 10.
